    Full Text Available After two decades of microbicide clinical trials it remains uncertain if vaginally- delivered products will be clearly shown to reduce the risk of HIV infection in women and girls. Furthermore, a microbicide product with demonstrated clinical efficacy must be used correctly and consistently if it is to prevent infection. Information on adherence that can be gleaned from microbicide trials is relevant for future microbicide safety and efficacy trials, pre-licensure implementation trials, Phase IV post-marketing research, and microbicide introduction and delivery. Drawing primarily from data and experience that has emerged from the large-scale microbicide efficacy trials completed to-date, the paper identifies six broad areas of adherence lessons learned: (1 Adherence measurement in clinical trials, (2 Comprehension of use instructions/Instructions for use, (3 Unknown efficacy and its effect on adherence/Messages regarding effectiveness, (4 Partner influence on use, (5 Retention and continuation and (6 Generalizability of trial participants' adherence behavior. Each is discussed, with examples provided from microbicide trials. For each of these adherence topics, recommendations are provided for using trial findings to prepare for future microbicide safety and efficacy trials, Phase IV post-marketing research, and microbicide introduction and delivery programs.

    Many people newly diagnosed with HIV are lost to follow-up before timely initiation of antiretroviral therapy (ART). A randomised controlled trial (RCT), WelTel Kenya1, demonstrated the effectiveness of the WelTel text messaging intervention to improve clinical outcomes among patients initiating ART. In preparation for WelTel Retain, an RCT that will evaluate the effect of the intervention to retain patients in care immediately following HIV diagnosis, we conducted an informative qualitative study with people living with HIV (n = 15) and healthcare providers (HCP) (n = 5) in October 2012. Study objectives included exploring the experiences of people living with HIV who have attempted to engage in HIV care, the use of cell phones in everyday life, and perceptions of communicating via text message with HCP. Participants were recruited through convenience sampling. Semi-structured, qualitative interviews were conducted and recorded, transcribed verbatim and analysed using NVivo software. Analysis was guided by the Theory of Reasoned Action and the Technology Acceptance Model. Results indicate that while individuals have many motivators for engaging in care after diagnosis, structural and individual barriers including poverty, depression and fear of stigma prevent them from doing so. All participants had access to a mobile phone, and most were comfortable communicating through text messages, or were willing to learn. Both people living with HIV and HCP felt that increased communication via the text messaging intervention has the potential to enable early identification of problems, leading to timely problem solving that may improve retention and engagement in care during the first year after diagnosis.

    Objective Psychopharmacology remains the foundation of treatment for bipolar disorder, but medication adherence in this population is low (Range = 20% to 64%). We examined medication adherence in a multi-site, comparative effectiveness study of lithium. Method The Lithium Moderate Dose Use Study (LiTMUS) was a six-month, six-site, randomized effectiveness trial of adjunctive moderate dose lithium therapy compared to optimized treatment in adult outpatients with bipolar I or II disorder (N=283). Medication adherence was measured at each study visit with the Tablet Routine Questionnaire. Results We found that 4.50% of participants reported missing at least 30% of their medications in the past week at baseline and non-adherence remained low throughout the trial (< 7%). Poor medication adherence was associated with more manic symptoms and side effects as well as lower lithium serum levels at mid- and post-treatment, but not with poor quality of life, overall severity of illness, or depressive symptoms. Conclusion Participants in LiTMUS were highly adherent with taking their medications. The lack of association with possible predictors of adherence, such as depression and quality of life, could be explained by the limited variance or other factors as well as by not using an objective measure of adherence.

  4. Methods for measuring, enhancing, and accounting for medication adherence in clinical trials.

    Vrijens, B; Urquhart, J

    2014-06-01

    Adherence to rationally prescribed medications is essential for effective pharmacotherapy. However, widely variable adherence to protocol-specified dosing regimens is prevalent among participants in ambulatory drug trials, mostly manifested in the form of underdosing. Drug actions are inherently dose and time dependent, and as a result, variable underdosing diminishes the actions of trial medications by various degrees. The ensuing combination of increased variability and decreased magnitude of trial drug actions reduces statistical power to discern between-group differences in drug actions. Variable underdosing has many adverse consequences, some of which can be mitigated by the combination of reliable measurements of ambulatory patients' adherence to trial and nontrial medications, measurement-guided management of adherence, statistically and pharmacometrically sound analyses, and modifications in trial design. Although nonadherence is prevalent across all therapeutic areas in which the patients are responsible for treatment administration, the significance of the adverse consequences depends on the characteristics of both the disease and the medications.

    Full Text Available Abstract Background To determine factors that predict adherence to a mind-body intervention in a randomized trial. Design We analyzed adherence data from a 3-arm trial involving 135 generally healthy seniors 65–85 years of age randomized to a 6-month intervention consisting of: an Iyengar yoga class with home practice, an exercise class with home practice, or a wait-list control group. Outcome measures included cognitive function, mood, fatigue, anxiety, health-related quality of life, and physical measures. Adherence to the intervention was obtained by class attendance and biweekly home practice logs. Results The drop-out rate was 13%. Among the completers of the two active interventions, average yoga class attendance was 77% and home practice occurred 64% of all days. Average exercise class attendance was 69% and home exercise occurred 54% of all days. There were no clear effects of adherence on the significant study outcomes (quality of life and physical measures. Class attendance was significantly correlated with baseline measures of depression, fatigue, and physical components of health-related quality of life. Significant differences in baseline measures were also found between study completers and drop-outs in the active interventions. Adherence was not related to age, gender, or education level. Conclusion Healthy seniors have good attendance at classes with a physically active intervention. Home practice takes place over half of the time. Decreased adherence to a potentially beneficial intervention has the potential to decrease the effect of the intervention in a clinical trial because subjects who might sustain the greatest benefit will receive a lower dose of the intervention and subjects with higher adherence rates may be functioning closer to maximum ability before the intervention. Strategies to maximize adherence among subjects at greater risk for low adherence will be important for future trials, especially complementary

    Adherence of participants in a long-term clinical trial is necessary to assure validity of findings. This article examines adherence differences between single-parent and two-parent families in the Childhood Asthma Management Program (CAMP). Adherence was defined as the percentage of completed daily diary cards and scheduled study visits during the course of the trial. Logistic regression and ordinal logistic regression analyses were used. Children from single-parent families had a lower percentage of completed diary cards (72% vs. 84%) than two-parent families. Single-parent families were also more likely to reschedule visits (62% vs. 45%) and miss more clinic visits (23% vs. 17%) than two-parent families. Suggestions are given for study coordinators to assist participants in completing a long-term clinical trial. Many suggestions may be adapted for nurses in inpatient or outpatient settings for assisting parents of patients with chronic diseases.

  7. Financial incentives to improve adherence to anti-psychotic maintenance medication in non-adherent patients - a cluster randomised controlled trial (FIAT

    2009-09-01

    Full Text Available Abstract Background Various interventions have been tested to achieve adherence to anti-psychotic maintenance medication in non-adherent patients with psychotic disorders, and there is no consistent evidence for the effectiveness of any established intervention. The effectiveness of financial incentives in improving adherence to a range of treatments has been demonstrated; no randomised controlled trial however has tested the use of financial incentives to achieve medication adherence for patients with psychotic disorders living in the community. Methods/Design In a cluster randomised controlled trial, 34 mental health teams caring for difficult to engage patients in the community will be randomly allocated to either the intervention group, where patients will be offered a financial incentive for each anti-psychotic depot medication they receive over a 12 month period, or the control group, where all patients will receive treatment as usual. We will recruit 136 patients with psychotic disorders who use these services and who have problems adhering to antipsychotic depot medication, although all conventional methods to achieve adherence have been tried. The primary outcome will be adherence levels, and secondary outcomes are global clinical improvement, number of voluntary and involuntary hospital admissions, number of attempted and completed suicides, incidents of physical violence, number of police arrests, number of days spent in work/training/education, subjective quality of life and satisfaction with medication. We will also establish the cost effectiveness of offering financial incentives. Discussion The study aims to provide new evidence on the effectiveness and cost effectiveness of offering financial incentives to patients with psychotic disorders to adhere to antipsychotic maintenance medication. If financial incentives improve adherence and lead to better health and social outcomes, they may be recommended as one option to improve the

  9. An interdisciplinary framework for measuring and supporting adherence in HIV prevention trials of ARV-based vaginal rings

    Kathleen M MacQueen

    2014-09-01

    Full Text Available Introduction: Product adherence and its measurement have emerged as a critical challenge in the evaluation of new HIV prevention technologies. Long-acting ARV-based vaginal rings may simplify use instructions and require less user behaviour, thereby facilitating adherence. One ARV-based ring is in efficacy trials and others, including multipurpose rings, are in the pipeline. Participant motivations, counselling support and measurement challenges during ring trials must still be addressed. In previous HIV prevention trials, this has been done largely using descriptive and post-hoc methods that are highly variable and minimally evaluated. We outline an interdisciplinary framework for systematically investigating promising strategies to support product uptake and adherence, and to measure adherence in the context of randomized, blinded clinical trials. Discussion: The interdisciplinary framework highlights the dual use of adherence measurement (i.e. to provide feedback during trial implementation and to inform interpretation of trial findings and underscores the complex pathways that connect measurement, adherence support and enacted adherence behaviour. Three inter-related approaches are highlighted: 1 adherence support – sequential efforts to define motivators of study product adherence and to develop, test, refine and evaluate adherence support messages; 2 self-reported psychometric measures – creation of valid and generalizable measures based in easily administered scales that capture vaginal ring use with improved predictive ability at screening, baseline and follow-up that better engage participants in reporting adherence; and 3 more objective measurement of adherence – real-time adherence monitoring and cumulative measurement to correlate adherence with overall product effectiveness through innovative designs, models and prototypes using electronic and biometric technologies to detect ring insertion and/or removal or expulsion

  10. Efficacy of a brief multifactorial adherence-based intervention on reducing the blood pressure of patients with poor adherence: protocol for a randomized clinical trial

    Llobera Joan

    2010-09-01

    Full Text Available Abstract Background Lowering of blood pressure by antihypertensive drugs reduces the risks of cardiovascular events, stroke, and total mortality. However, poor adherence to antihypertensive medications reduces their effectiveness and increases the risk of adverse events. In terms of relative risk reduction, an improvement in medication adherence could be as effective as the development of a new drug. Methods/Design The proposed randomized controlled trial will include patients with a low adherence to medication and uncontrolled blood pressure. The intervention group will receive a multifactorial intervention during the first, third, and ninth months, to improve adherence. This intervention will include motivational interviews, pill reminders, family support, blood pressure self-recording, and simplification of the dosing regimen. Measurement The primary outcome is systolic blood pressure. The secondary outcomes are diastolic blood pressure, proportion of patients with adequately controlled blood pressure, and total cost. Discussion The trial will evaluate the impact of a multifactorial adherence intervention in routine clinical practice.

  11. Adherence to antiretroviral prophylaxis for HIV prevention: a substudy cohort within a clinical trial of serodiscordant couples in East Africa.

    Jessica E Haberer

    Full Text Available Randomized clinical trials of oral antiretroviral pre-exposure prophylaxis (PrEP for HIV prevention have widely divergent efficacy estimates, ranging from 0% to 75%. These discrepancies are likely due to differences in adherence. To our knowledge, no studies to date have examined the impact of improving adherence through monitoring and/or intervention, which may increase PrEP efficacy, or reported on objective behavioral measures of adherence, which can inform PrEP effectiveness and implementation.Within the Partners PrEP Study (a randomized placebo-controlled trial of oral tenofovir and emtricitabine/tenofovir among HIV-uninfected members of serodiscordant couples in Kenya and Uganda, we collected objective measures of PrEP adherence using unannounced home-based pill counts and electronic pill bottle monitoring. Participants received individual and couples-based adherence counseling at PrEP initiation and throughout the study; counseling was intensified if unannounced pill count adherence fell to 80% adherence. Study limitations include potential shortcomings of the adherence measures and use of a convenience sample within the substudy cohort.The high PrEP adherence achieved in the setting of active adherence monitoring and counseling support was associated with a high degree of protection from HIV acquisition by the HIV-uninfected partner in heterosexual serodiscordant couples. Low PrEP adherence was associated with sexual behavior, alcohol use, younger age, and length of PrEP use. Please see later in the article for the Editors' Summary.

  13. Randomized controlled trial of a mobile phone intervention for improving adherence to naltrexone for alcohol use disorders.

    Susan A Stoner

    Full Text Available Naltrexone is a front-line treatment for alcohol use disorders, but its efficacy is limited by poor medication adherence. This randomized controlled trial evaluated whether a mobile health intervention could improve naltrexone adherence.Treatment-seeking participants with an alcohol use disorder (N = 76 were randomized to intervention and control conditions. All participants received naltrexone (50 mg/day with a medication event monitoring system (MEMS and a prepaid smartphone, and received a daily text message querying medication side effects, alcohol use, and craving. Those in the intervention arm received additional medication reminders and adherence assessment via text message.The primary outcome, proportion of participants with adequate adherence (defined as ≥80% of prescribed doses taken through Week 8, did not differ between groups in intent-to-treat analyses (p = .34. Mean adherence at study midpoint (Week 4 was 83% in the intervention condition and 77% in the control condition (p = .35. Survival analysis found that the intervention group sustained adequate adherence significantly longer (M = 19 days [95% CI = 0.0-44.0] than those in the control group (M = 3 days [95% CI = 0.0-8.1] during the first month of treatment (p = .04. Medication adherence did not predict drinking outcomes.These results suggest that in the context of daily monitoring and assessment via cell phone, additional text message reminders do not further improve medication adherence. Although this initial trial does not provide support for the efficacy of text messaging to improve adherence to pharmacotherapy for alcohol use disorders, additional trials with larger samples and alternate designs are warranted.ClinicalTrials.gov: NCT01349985.

    Full Text Available Mobile text messaging and medication monitors (medication monitor boxes have the potential to improve adherence to tuberculosis (TB treatment and reduce the need for directly observed treatment (DOT, but to our knowledge they have not been properly evaluated in TB patients. We assessed the effectiveness of text messaging and medication monitors to improve medication adherence in TB patients.In a pragmatic cluster-randomised trial, 36 districts/counties (each with at least 300 active pulmonary TB patients registered in 2009 within the provinces of Heilongjiang, Jiangsu, Hunan, and Chongqing, China, were randomised using stratification and restriction to one of four case-management approaches in which patients received reminders via text messages, a medication monitor, combined, or neither (control. Patients in the intervention arms received reminders to take their drugs and reminders for monthly follow-up visits, and the managing doctor was recommended to switch patients with adherence problems to more intensive management or DOT. In all arms, patients took medications out of a medication monitor box, which recorded when the box was opened, but the box gave reminders only in the medication monitor and combined arms. Patients were followed up for 6 mo. The primary endpoint was the percentage of patient-months on TB treatment where at least 20% of doses were missed as measured by pill count and failure to open the medication monitor box. Secondary endpoints included additional adherence and standard treatment outcome measures. Interventions were not masked to study staff and patients. From 1 June 2011 to 7 March 2012, 4,292 new pulmonary TB patients were enrolled across the 36 clusters. A total of 119 patients (by arm: 33 control, 33 text messaging, 23 medication monitor, 30 combined withdrew from the study in the first month because they were reassessed as not having TB by their managing doctor (61 patients or were switched to a different

    2011-12-01

    Full Text Available Abstract Background Efficacious strategies for the primary prevention of coronary heart disease (CHD are underused, and, when used, have low adherence. Existing efforts to improve use and adherence to these efficacious strategies have been so intensive that they are impractical for clinical practice. Methods We conducted a randomized trial of a CHD prevention intervention (including a computerized decision aid and automated tailored adherence messages at one university general internal medicine practice. After obtaining informed consent and collecting baseline data, we randomized patients (men and women age 40-79 with no prior history of cardiovascular disease to either the intervention or usual care. We then saw them for two additional study visits over 3 months. For intervention participants, we administered the decision aid at the primary study visit (1 week after baseline visit and then mailed 3 tailored adherence reminders at 2, 4, and 6 weeks. We assessed our outcomes (including the predicted likelihood of angina, myocardial infarction, and CHD death over 10 years (CHD risk and self-reported adherence between groups at 3 month follow-up. Data collection occurred from June 2007 through December 2009. All study procedures were IRB approved. Results We randomized 160 eligible patients (81 intervention; 79 control and followed 96% to study conclusion. Mean predicted CHD risk at baseline was 11.3%. The intervention increased self-reported adherence to chosen risk reducing strategies by 25 percentage points (95% CI 8% to 42%, with the biggest effect for aspirin. It also changed predicted CHD risk by -1.1% (95% CI -0.16% to -2%, with a larger effect in a pre-specified subgroup of high risk patients. Conclusion A computerized intervention that involves patients in CHD decision making and supports adherence to effective prevention strategies can improve adherence and reduce predicted CHD risk.

    Full Text Available Introduction: Medication nonadherence is highly prevalent in patients with bipolar disorders and often results in worsening disease prognosis. The purpose of this study was to investigate the effect of group psychoeducation on medication adherence in female patients with bipolar mood disorder type I. Methods: This randomized controlled trial was conducted on 76 patients with bipolar mood disorder admitted in female psychiatric wards of Razi teaching hospital, Tabriz, Iran. The participants were selected by convenience sampling method and were randomly assigned to experimental and control groups. Patients in experimental group received 10 continuous 90 minutes sessions of psychoeducation, two times a week. Medication adherence was measured using the medicine check list and medication adherence rating scale (MARS before and after intervention. Data analysis was performed with SPSS ver.13. Results: There was no significant difference between two groups regarding medication adherence before the intervention. After the study intervention, the mean scores of medication adherence check list and medication adherence rating scale in the experimental group were significantly higher than the control group. Conclusion: Since group psychoeducation was effective in improving patients' medication adherence, it could be recommended for psychiatric nurses to apply this intervention in the clinical setting.

    This study determined whether motivational interviewing-based cognitive behavioral therapy (MI-CBT) adherence counseling combined with modified directly observed therapy (MI-CBT/mDOT) is more effective than MI-CBT counseling alone or standard care (SC) in increasing adherence over time. A three-armed randomized controlled 48-week trial with continuous electronic drug monitored adherence was conducted by randomly assigning 204 HIV-positive participants to either 10 sessions of MI-CBT counseling with mDOT for 24 weeks, 10 sessions of MI-CBT counseling alone, or SC. Poisson mixed effects regression models revealed significant interaction effects of intervention over time on non-adherence defined as percent of doses not-taken (IRR = 1.011, CI = 1.000-1.018) and percent of doses not-taken on time (IRR = 1.006, CI = 1.001-1.011) in the 30 days preceding each assessment. There were no significant differences between groups, but trends were observed for the MI-CBT/mDOT group to have greater 12 week on-time and worse 48 week adherence than the SC group. Findings of modest to null impact on adherence despite intensive interventions highlights the need for more effective interventions to maintain high adherence over time.

  20. The impact of supervision on stock management and adherence to treatment guidelines: a randomized controlled trial.

    2001-09-01

    Ensuring the availability of essential drugs and using them appropriately are crucial if limited resources for health care are to be used optimally. While training of health workers throughout Zimbabwe in drug management (including stock management and rational drug use) resulted in significant improvements in a variety of drug use indicators, these achievements could not be sustained, and a new strategy was introduced based on the supervision of primary health care providers. This was launched in 1995 with a training course in supervisory skills for district pharmacy staff. In order to evaluate the impact of the supervision and the effectiveness of the training programme, adherence to standard treatment guidelines (STG) and stock management protocols was evaluated in a randomized controlled trial. The study compared three different groups of health facilities: those that received supervision for either use of STG (n = 23) or stock management (n = 21) - each facility acting as control for the other area of supervision - and a comparison group of facilities which received no supervision (n = 18). On-the-spot supervision by a specially trained pharmacy staff, based around identified deficiencies, took place at the start of the study and 3 months later. The evaluation compared performance on a variety of drug management indicators at baseline and 6-8 months after the second supervisory visit. The results of the study showed that, following supervision, overall stock management improved significantly when compared with the control and comparison groups. Similar improvements were demonstrated for adherence to STG, although the effect was confounded by other interventions. The study also showed that supervision has a positive effect on improving performance in areas other than those supervised, and demonstrated that pharmacy technicians with limited clinical skills can be trained to influence primary health care workers to positively improve prescribing practices

  1. Discontinuing financial incentives for adherence to antipsychotic depot medication: long-term outcomes of a cluster randomised controlled trial

    2016-01-01

    Objectives In a cluster randomised controlled trial, offering financial incentives improved adherence to antipsychotic depot medication over a 1-year period. Yet, it is unknown whether this positive effect is sustained once the incentives stop. Methods and analyses Patients in the intervention and control group were followed up for 2 years after the intervention. Primary and secondary outcomes were assessed at 6 months and 24 months post intervention. Assessments were conducted between September 2011 and November 2014. Results After the intervention period, intervention and control groups did not show any statistically significant differences in adherence, neither in the first 6 months (71% and 77%, respectively) nor in the following 18 months (68%, 74%). There were no statistically significant differences in secondary outcomes, that is, adherence ≥95% and untoward incidents either. Conclusions It may be concluded that incentives to improve adherence to antipsychotic maintenance medication are effective only for as long as they are provided. Once they are stopped, adherence returns to approximately baseline level with no sustained benefit. Trial registration number ISRCTN77769281; Results. PMID:27655261

    Objective: India is home to the third-largest number of people living with HIV in the world, and no-cost antiretroviral therapy (ART) has been available across the country since 2004. However, rates of adherence to ART are often subpar in India, and interventions to increase adherence are warranted. Cognitive impairment and depression have been associated with ART non-adherence, and may also limit the impact of behavioral interventions designed to improve adherence. Studies have not evaluated...

  3. The impact of text message reminders on adherence to antimalarial treatment in northern Ghana: a randomized trial.

    Julia R G Raifman

    Full Text Available BACKGROUND: Low rates of adherence to artemisinin-based combination therapy (ACT regimens increase the risk of treatment failure and may lead to drug resistance, threatening the sustainability of current anti-malarial efforts. We assessed the impact of text message reminders on adherence to ACT regimens. METHODS: Health workers at hospitals, clinics, pharmacies, and other stationary ACT distributors in Tamale, Ghana provided flyers advertising free mobile health information to individuals receiving malaria treatment. The messaging system automatically randomized self-enrolled individuals to the control group or the treatment group with equal probability; those in the treatment group were further randomly assigned to receive a simple text message reminder or the simple reminder plus an additional statement about adherence in 12-hour intervals. The main outcome was self-reported adherence based on follow-up interviews occurring three days after treatment initiation. We estimated the impact of the messages on treatment completion using logistic regression. RESULTS: 1140 individuals enrolled in both the study and the text reminder system. Among individuals in the control group, 61.5% took the full course of treatment. The simple text message reminders increased the odds of adherence (adjusted OR 1.45, 95% CI [1.03 to 2.04], p-value 0.028. Receiving an additional message did not result in a significant change in adherence (adjusted OR 0.77, 95% CI [0.50 to 1.20], p-value 0.252. CONCLUSION: The results of this study suggest that a simple text message reminder can increase adherence to antimalarial treatment and that additional information included in messages does not have a significant impact on completion of ACT treatment. Further research is needed to develop the most effective text message content and frequency. TRIAL REGISTRATION: ClinicalTrials.gov NCT01722734.

    Full Text Available The favorable outcome of the treatment of a disease is influenced by the adherence to therapy. Our objective was to assess factors associated with adherence to treatment of patients included in a clinical trial of equivalence between the standard and alternative treatment schemes with meglumine antimoniate (MA in the treatment of cutaneous leishmaniasis (CL, in the state of Rio de Janeiro. Between 2008 and 2011, 57 patients with CL were interviewed using a questionnaire to collect socioeconomic data. The following methods were used for adherence monitoring: counting of vial surplus, monitoring card, Morisky test and modified Morisky test (without the question regarding the schedule; we observed 82.1% (vial return, 86.0% (monitoring card, 66.7% (Morisky test and 86.0% (modified Morisky test adherence. There was a strong correlation between the method of vial counting and the monitoring card and modified Morisky test. A significant association was observed between greater adherence to treatment and low dose of MA, as well as with a lower number of people sleeping in the same room. We recommend the use of the modified Morisky test to assess adherence to treatment of CL with MA, because it is a simple method and with a good performance, when compared to other methods.

    The impact of pill organizers on pill taking was determined in the Trial of Antioxidant Vitamins C and E (TRACE) Study, a factorial trial of vitamin C and vitamin E supplementation in 184 individuals. Participants were recruited in 1996-1997 and randomized to one of two groups (pill organizer or no organizer) and to one of four supplement groups for 2 months. The pill count (observed/expected X 100%) distribution was similar in the organizer and no organizer group for both vitamins. Mean differences in changes in serum vitamin levels between active and placebo groups did not differ by pill organizer use. The impact of pill organizers and blister packs was compared in another trial, the Vitamins, Teachers, and Longevity (VITAL) Study, in 297 individuals randomized in 1993-1994 to receive study pills either in blister packs or in pill organizers and to take one of two supplements. Among those with lower adherence, the pill count distribution in the blister-pack group exceeded that in the organizer group. Mean differences in serum vitamin E levels between active and placebo groups did not differ by types of pill packaging. In summary, use of blister packs, but not pill organizers, improved adherence as measured by pill counts among those with lower adherence. Neither pill delivery system improved adherence as measured by serum vitamin levels.

This feasibility study evaluated the measures to be used for a future randomized controlled trial assessing the effects of group-based education on adherence with eye drops. Methods: People diagnosed with glaucoma within the previous 12 months attending a regional ophthalmology clinic in the North West of England were recruited. A two-session education program delivered one week apart had been devised as part of a previous project. A combined adult learning and health needs approach to education was taken. Outcomes measured were knowledge of glaucoma, self-report of adherence, illness perception, beliefs about medicines, patient enablement, and general health (Short Form-12. Adherence was also measured objectively using a Medical Events Monitoring System device. Results: Twenty-six participants consented to undertake the educational program and 19 produced analyzable data. Knowledge of glaucoma, illness perception, beliefs about medicine, and patient enablement all showed statistically significant improvements after education. Mean adherence with eye drops was maintained above 85% before and for 3 months after attendance at the educational program. Self-report exaggerated adherence by at least 10% when compared with the objective Medical Events Monitoring System data, and in fact the kappa agreement was zero. Conclusion: All questionnaires other than the Short Form-12 were considered to be valuable measures and use of a Medical Events Monitoring System device was

    Full Text Available INTRODUCTION: The MAINTAIN study is an on-going RCT comparing high-dose micronutrient and anti-oxidant supplementation versus recommended daily allowance (RDA vitamins in slowing HIV immune deficiency progression in ART-naïve people with HIV infection. OBJECTIVE: We planned analysis of the first 127 participants to determine the baseline prevalence of serum micronutrient deficiencies and correlates, as well as tolerance and adherence to study interventions. METHODS: Participants receive eight capsules twice daily of 1 high-dose or 2 RDA supplements for two years and are followed-up quarterly for measures of immune deficiency progression, safety and tolerability. Regression analysis was used to identify correlates of micronutrient levels at baseline. Adherence was measured by residual pill count, self-report using the General Treatment Scale (GTS and short-term recall HIV Adherence Treatment Scale (HATS. RESULTS: Prior micronutrient supplementation (within 30 days was 27% at screening and 10% of study population, and was not correlated with baseline micronutrient levels. Low levels were frequent for carotene (24%80% in 75% of participants. CONCLUSION: Micronutrient levels in asymptomatic HIV+ persons are in keeping with population norms, but micronutrient deficiencies are frequent. Adherence levels are high, and will permit a valid evaluation of treatment effects. TRIAL REGISTRATION: ClinicalTrials.gov NCT00798772.

    2014-12-01

    Full Text Available Background: Effective interventions to improve medication adherence are usually complex and expensive. Objective: To assess the impact of a low-cost intervention designed to improve medication adherence and clinical outcomes in post-discharge patients with CVD. Method: A pilot RCT was conducted at a teaching hospital. Intervention was based on the four-item Morisky Medication Adherence Scale (MMAS-4. The primary outcome measure was medication adherence assessed using the eight-item MMAS at baseline, at 1 month post hospital discharge and re-assessed 1 year after hospital discharge. Other outcomes included readmission and mortality rates. Results: 61 patients were randomized to intervention (n = 30 and control (n = 31 groups. The mean age of the patients was 61 years (SD 12.73, 52.5% were males, and 57.4% were married or living with a partner. Mean number of prescribed medications per patient was 4.5 (SD 3.3. Medication adherence was correlated to intervention (p = 0.04 and after 1 month, 48.4% of patients in the control group and 83.3% in the intervention group were considered adherent. However, this difference decreased after 1 year, when adherence was 34.8% and 60.9%, respectively. Readmission and mortality rates were related to low adherence in both groups. Conclusion: The intervention based on a validated patient self-report instrument for assessing adherence is a potentially effective method to improve adherent behavior and can be successfully used as a tool to guide adherence counseling in the clinical visit. However, a larger study is required to assess the real impact of intervention on these outcomes.

  10. A Multifaceted Prospective Memory Intervention to Improve Medication Adherence: Design of a Randomized Control Trial

    Adherence to prescribed antihypertensive agents is critical because control of elevated blood pressure is the single most important way to prevent stroke and other end organ damage. Unfortunately, nonadherence remains a significant problem. Previous interventions designed to improve adherence have demonstrated only small benefits of strategies that target single facets such as understanding medication directions. The intervention described here is informed by prospective memory theory and performance of older adults in laboratory-based paradigms and uses a comprehensive, multifaceted approach to improve adherence. It incorporates multiple strategies designed to support key components of prospective remembering involved in taking medication. The intervention is delivered by nurses in the home with an education control group for comparison. Differences between groups in overall adherence following the intervention and 6 months later will be tested. Systolic and diastolic blood pressure levels also will be examined between groups and as it relates to adherence. Intra-individual regression is planned to examine change in adherence over time and its predictors. Finally, we will examine the association between executive function/working memory and adherence, predicting that adherence will be related to executive/working memory in the control group but not in the intervention group.

    ABSTRACT OBJECTIVE To assess the effect of educational dietary intervention offered in the child’s first year of life, as well as teenage mothers and grandmothers in carrying out the dietary recommendations at four to seven years. METHODS Randomized clinical trial initiated in 2006, in Porto Alegre, RS, involving 323 teenage mothers and grandmothers who cohabited. The intervention consisted of six counseling sessions on breastfeeding and healthy complementary feeding. The first session occurred in the maternity ward and the other ones in the households of mothers at seven, 15, 30, 60, and 120 days of the child’s life. The information about the child’s diet were obtained on a monthly basis in the first six months, every two months in the second half-year, and at four to seven years, using a food frequency questionnaire. To assess the adequacy of food consumption to the recommendations from the Ministry of Health, we elaborated a score system that would reflect the compliance with the Ten Steps for Healthy Toddlers from 2 to 10 Years. The average scores of intervention and control groups were compared using the t-test. RESULTS Low adherence to recommendations on child nutrition was found in the study population, with no difference in implementation the steps between the groups. The score on the compliance with the steps was similar in both groups (9.6 [SD = 1.63] and 9.3 [SD = 1.60] in the intervention and control groups, respectively) and no influence of the cohabitation with the grandmother was found. CONCLUSIONS Educational dietary intervention in the first four months of the child’s life for teenage mothers and grandmothers had no effect on the compliance with the recommendations at four to seven years of the child’s life.

    Full Text Available BACKGROUND: Behavioral interventions that promote adherence to antiretroviral medications may decrease HIV treatment failure. Antiretroviral treatment programs in sub-Saharan Africa confront increasing financial constraints to provide comprehensive HIV care, which include adherence interventions. This study compared the impact of counseling and use of an alarm device on adherence and biological outcomes in a resource-limited setting. METHODS AND FINDINGS: A randomized controlled, factorial designed trial was conducted in Nairobi, Kenya. Antiretroviral-naïve individuals initiating free highly active antiretroviral therapy (HAART in the form of fixed-dose combination pills (d4T, 3TC, and nevirapine were randomized to one of four arms: counseling (three counseling sessions around HAART initiation, alarm (pocket electronic pill reminder carried for 6 months, counseling plus alarm, and neither counseling nor alarm. Participants were followed for 18 months after HAART initiation. Primary study endpoints included plasma HIV-1 RNA and CD4 count every 6 months, mortality, and adherence measured by monthly pill count. Between May 2006 and September 2008, 400 individuals were enrolled, 362 initiated HAART, and 310 completed follow-up. Participants who received counseling were 29% less likely to have monthly adherence <80% (hazard ratio [HR] = 0.71; 95% confidence interval [CI] 0.49-1.01; p = 0.055 and 59% less likely to experience viral failure (HIV-1 RNA ≥5,000 copies/ml (HR 0.41; 95% CI 0.21-0.81; p = 0.01 compared to those who received no counseling. There was no significant impact of using an alarm on poor adherence (HR 0.93; 95% CI 0.65-1.32; p = 0.7 or viral failure (HR 0.99; 95% CI 0.53-1.84; p = 1.0 compared to those who did not use an alarm. Neither counseling nor alarm was significantly associated with mortality or rate of immune reconstitution. CONCLUSIONS: Intensive early adherence counseling at HAART initiation resulted

    The primary aim was to examine the preliminary efficacy of a family tailored problem-solving intervention to improve antiepileptic drug (AED) adherence in families of children with new-onset epilepsy. Secondary aims were to assess changes in targeted mechanisms and treatment feasibility and acceptability. Fifty families (M(age) = 7.6 ± 3.0; 80% Caucasian; 42% idiopathic localization related) completed baseline questionnaires and were given an electronic monitor to observe daily AED adherence. If adherence was ≤ 95% in the first 7 months of the study, families were randomized (Supporting Treatment Adherence Regimens (STAR): n = 11; Treatment as Usual (TAU): n = 12). Twenty-one families were not randomized due to adherence being ≥95%. The STAR intervention included four face-to-face and two telephone problem-solving sessions over 8 weeks. Significant group differences in adherence were found during active intervention (weeks 4-6; TAU = -12.0 vs. STAR = 18.1, p < 0.01; and weeks session 6-8: TAU = -9.7 vs. STAR = 15.3, p < 0.05). Children who received the STAR intervention exhibited improved adherence compared to children in the TAU group during active treatment. Significant changes in epilepsy knowledge and management were noted for the STAR group. Families expressed benefitting from the STAR intervention. Future studies should include a larger sample size and booster intervention sessions to maintain treatment effects over time.

    2016-11-01

    We conducted two studies to test the validity, reliability, feasibility and acceptability of using video chat technology to quantify dietary and pill-taking (i.e. supplement and medication) adherence. In study 1, we investigated whether video chat technology can accurately quantify adherence to dietary and pill-taking interventions. Mock study participants ate food items and swallowed pills, while performing randomised scripted 'cheating' behaviours to mimic non-adherence. Monitoring was conducted in a cross-over design, with two monitors watching in-person and two watching remotely by Skype on a smartphone. For study 2, a twenty-two-item online survey was sent to a listserv with more than 20 000 unique email addresses of past and present study participants to assess the feasibility and acceptability of the technology. For the dietary adherence tests, monitors detected 86 % of non-adherent events (sensitivity) in-person v. 78 % of events via video chat monitoring (P=0·12), with comparable inter-rater agreement (0·88 v. 0·85; P=0·62). However, for pill-taking, non-adherence trended towards being more easily detected in-person than by video chat (77 v. 60 %; P=0·08), with non-significantly higher inter-rater agreement (0·85 v. 0·69; P=0·21). Survey results from study 2 (n 1076 respondents; ≥5 % response rate) indicated that 86·4 % of study participants had video chatting hardware, 73·3 % were comfortable using the technology and 79·8 % were willing to use it for clinical research. Given the capability of video chat technology to reduce participant burden and outperform other adherence monitoring methods such as dietary self-report and pill counts, video chatting is a novel and promising platform to quantify dietary and pill-taking adherence.

    2010-11-01

    Full Text Available Abstract Background The behavioural impact of pharmacogenomics is untested; informing smokers of genetic test results for responsiveness to smoking cessation medication may increase adherence to this medication. The objective of this trial is to estimate the impact upon adherence to nicotine replacement therapy (NRT of informing smokers that their oral dose of NRT has been tailored to a DNA analysis. Hypotheses to be tested are as follows: IAdherence to NRT is greater among smokers informed that their oral dose of NRT is tailored to an analysis of DNA (genotype, compared to one tailored to nicotine dependence questionnaire score (phenotype. II Amongst smokers who fail to quit at six months, motivation to make another quit attempt is lower when informed that their oral dose of NRT was tailored to genotype rather than phenotype. Methods/Design An open label, parallel groups randomised trial in which 630 adult smokers (smoking 10 or more cigarettes daily using National Health Service (NHS stop smoking services in primary care are randomly allocated to one of two groups: i. NRT oral dose tailored by DNA analysis (OPRM1 gene (genotype, or ii. NRT oral dose tailored by nicotine dependence questionnaire score (phenotype The primary outcome is proportion of prescribed NRT consumed in the first 28 days following an initial quit attempt, with the secondary outcome being motivation to make another quit attempt, amongst smokers not abstinent at six months. Other outcomes include adherence to NRT in the first seven days and biochemically validated smoking abstinence at six months. The primary outcome will be collected on 630 smokers allowing sufficient power to detect a 7.5% difference in mean proportion of NRT consumed using a two-tailed test at the 5% level of significance between groups. The proportion of all NRT consumed in the first four weeks of quitting will be compared between arms using an independent samples t-test and by estimating the 95

    Saran, Indrani; Yavuz, Elif; Kasozi, Howard; Cohen, Jessica

    2016-04-01

    Most patients with suspected malaria do not receive diagnostic confirmation before beginning antimalarial treatment. We investigated the extent to which uncertainty about malaria diagnosis contributes to patient nonadherence to artemether-lumefantrine (AL) treatment through a randomized controlled trial in central Uganda. Among 1,525 patients purchasing a course of AL at private drug shops, we randomly offered 37.6% a free malaria rapid diagnostic test (RDT) and then assessed adherence through home visits 3 days later. Of these subjects, 68.4% tested positive for malaria and 65.8% adhered overall. Patients who tested positive did not have significantly higher odds of adherence than those who were not offered the test (adjusted odds ratio [OR]: 1.07, 95% confidence interval [CI]: 0.734-1.57,P= 0.719). Patients who received a positive malaria test had 0.488 fewer pills remaining than those not offered the test (95% CI: -1.02 to 0.043,P= 0.072). We found that patients who felt relatively healthy by the second day of treatment had lower odds of completing treatment (adjusted OR: 0.532, 95% CI: 0.394-0.719,Psymptoms have resolved.

    2012-11-01

    Full Text Available Abstract Background Adherences to treatments that require a behavioral action often rely on self-reported recall, yet it is vital to determine whether real time self reporting of adherence using a simple logbook accurately captures adherence. The purpose of this study was to determine whether real time self-reported adherence is an accurate measurement of device usage during a clinical trial by comparing it to electronic recording. Methods Using data collected from older adult men and women (N=135, mean age 82.3 yrs; range 66 to 98 yrs participating in a clinical trial evaluating a vibrating platform for the treatment of osteoporosis, daily adherence to platform treatment was monitored using both self-reported written logs and electronically recorded radio-frequency identification card usage, enabling a direct comparison of the two methods over one year. Agreement between methods was also evaluated after stratification by age, gender, time in study, and cognition status. Results The two methods were in high agreement (overall intraclass correlation coefficient = 0.96. The agreement between the two methods did not differ between age groups, sex, time in study and cognitive function. Conclusions Using a log book to report adherence to a daily intervention requiring a behavioral action in older adults is an accurate and simple approach to use in clinical trials, as evidenced by the high degree of concordance with an electronic monitor.

  4. Design of a randomized trial to evaluate the influence of mobile phone reminders on adherence to first line antiretroviral treatment in South India - the HIVIND study protocol

    Kumarasamy Nagalingeswaran

    2010-03-01

    Full Text Available Abstract Background Poor adherence to antiretroviral treatment has been a public health challenge associated with the treatment of HIV. Although different adherence-supporting interventions have been reported, their long term feasibility in low income settings remains uncertain. Thus, there is a need to explore sustainable contextual adherence aids in such settings, and to test these using rigorous scientific designs. The current ubiquity of mobile phones in many resource-constrained settings, make it a contextually appropriate and relatively low cost means of supporting adherence. In India, mobile phones have wide usage and acceptability and are potentially feasible tools for enhancing adherence to medications. This paper presents the study protocol for a trial, to evaluate the influence of mobile phone reminders on adherence to first-line antiretroviral treatment in South India. Methods/Design 600 treatment naïve patients eligible for first-line treatment as per the national antiretroviral treatment guidelines will be recruited into the trial at two clinics in South India. Patients will be randomized into control and intervention arms. The control arm will receive the standard of care; the intervention arm will receive the standard of care plus mobile phone reminders. Each reminder will take the form of an automated call and a picture message. Reminders will be delivered once a week, at a time chosen by the patient. Patients will be followed up for 24 months or till the primary outcome i.e. virological failure, is reached, whichever is earlier. Self-reported adherence is a secondary outcome. Analysis is by intention-to-treat. A cost-effectiveness study of the intervention will also be carried out. Discussion Stepping up telecommunications technology in resource-limited healthcare settings is a priority of the World Health Organization. The trial will evaluate if the use of mobile phone reminders can influence adherence to first

    2012-07-01

    Full Text Available Abstract Background Low adherence to chronic kidney disease (CKD guidelines may be due to unrecognized CKD and lack of guideline awareness on the part of providers. The goal of this study was to evaluate the impact of provider education and access to a CKD registry on guideline adherence. Methods We conducted a cluster randomized controlled trial at the Louis Stokes Cleveland VAMC. One of two primary care clinics was randomized to intervention. Providers from both clinics received a lecture on CKD guidelines at study initiation. Providers in the intervention clinic were given access to and shown how to use a CKD registry, which identifies patients with CKD and is automatically updated daily. Eligible patients had at least one primary care visit in the last year, had CKD based on eGFR, and had not received renal replacement therapy. The primary outcome was parathyroid hormone (PTH adherence, defined by at least one PTH measurement during the 12 month study. Secondary outcomes were measurement of phosphorus, hemoglobin, proteinuria, achievement of goal blood pressure, and treatment with a diuretic or renin-angiotensin system blocker. Results There were 418 and 363 eligible patients seen during the study in the control and intervention clinics, respectively. Compared to pre-intervention, measurement of PTH increased in both clinics (control clinic: 16% to 23%; intervention clinic: 13% to 28%. Patients in the intervention clinic were more likely to have a PTH measured during the study (adjusted odds ratio = 1.53; 95% CI (1.01, 2.30; P = 0.04. However, the intervention was not associated with a consistent improvement in secondary outcomes. Only 5 of the 37 providers in the intervention clinic accessed the registry. Conclusions An intervention that included education on CKD guidelines and access to a CKD patient registry marginally improved guideline adherence over education alone. Adherence to the primary process measure improved in both

    Consistent over-reporting of product use limits researchers' ability to accurately measure adherence and estimate product efficacy in HIV prevention trials. While lying is a universal characteristic of the human condition, growing evidence of a stark discrepancy between self-reported product use and biologic or pharmacokinetic evidence demands examination of the reasons research participants frequently misrepresent product use in order to mitigate this challenge in future research. This study (VOICE-D) was an ancillary post-trial study of the vaginal and oral interventions to control the epidemic (VOICE) phase IIb trial (MTN 003). It was conducted in three African countries to elicit candid accounts from former VOICE trial participants about why actual product use was lower than reported. In total 171 participants were enrolled between December 2012 and March 2014 in South Africa (n = 47), Uganda (n = 59) and Zimbabwe (n = 65). Data suggested that participants understood the importance of daily product use and honest reporting, yet acknowledged that research participants typically lie. Participants cited multiple reasons for misreporting adherence, including human nature, self-presentation with study staff, fear of repercussions (study termination resulting in loss of benefits and experience of HIV-related stigma), a permissive environment in which it was easy to get away with misreporting, and avoiding inconvenient additional counseling. Some participants also reported mistrust of the staff and reciprocal dishonesty about the study products. Many suggested real-time blood-monitoring during trials would encourage greater fidelity to product use and honesty in reporting. Participants at all sites understood the importance of daily product use and honesty, while also acknowledging widespread misreporting of product use. Narratives of dishonesty may suggest a wider social context of hiding products from partners and distrust about research, influenced by rumors

Regarding the importance of preventing dialysis adverse effects, which are in close connection with lack of knowledge and report on how to train the patients? This study aims at comparing the impact of two methods of face to face training and training pamphlet on complying and informing of hemodialysis treatments. Methods: This clinical trial study was conducted on 58 hemodialysis patients who visited Shahid Rahnemun Teaching hospital, Yazd, Iran, and had required conditions of the research. Data were collected through a questionnaire including personal-social information, several questions to assess the level of compliance and to inform the treatment method. The quantitative analysis of this study used the Statistical Package for Social Sciences SPSS version 13 and descriptive (frequency, mean, standard deviation and inferential (Chi-square, paired t-test, ANOVA, ANCOVA statistics were employed. Results: The mean scores for informing both groups (face to face and training pamphlet were significantly increased. The mean score for adherence to treatments was also significant.Conclusion: In this research, face to face training was found to be more effective than training pamphlet. It seemed to have more strong effect on increasing the level of information and adherence to treatment. To train these people, face to face training should be, thus, preferred.

  9. Risk factors for non-adherence and loss to follow-up in a three-year clinical trial in Botswana.

    Deborah A Gust

    Full Text Available BACKGROUND: Participant non-adherence and loss to follow-up can compromise the validity of clinical trial results. An assessment of these issues was made in a 3-year tuberculosis prevention trial among HIV-infected adults in Botswana. METHODS AND FINDINGS: Between 11/2004-07/2006, 1995 participants were enrolled at eight public health clinics. They returned monthly to receive bottles of medication and were expected to take daily tablets of isoniazid or placebo for three years. Non-adherence was defined as refusing tablet ingestion but agreeing to quarterly physical examinations. Loss to follow-up was defined as not having returned for appointments in ≥60 days. Between 10/2008-04/2009, survey interviews were conducted with 83 participants identified as lost to follow-up and 127 identified as non-adherent. As a comparison, 252 randomly selected adherent participants were also surveyed. Multivariate logistic regression analysis was used to identify associations with selected risk factors. Men had higher odds of being non-adherent (adjusted odds ratio (AOR, 2.24; 95% confidence interval [95%CI] 1.24-4.04 and lost to follow-up (AOR 3.08; 95%CI 1.50-6.33. Non-adherent participants had higher odds of reporting difficulties taking the regimen or not knowing if they had difficulties (AOR 3.40; 95%CI 1.75-6.60 and lower odds associated with each year of age (AOR 0.95; 95%CI 0.91-0.98, but other variables such as employment, distance from clinic, alcohol use, and understanding study requirements were not significantly different than controls. Among participants who were non-adherent or lost to follow-up, 40/210 (19.0% reported that they stopped the medication because of work commitments and 33/210 (15.7% said they thought they had completed the study. CONCLUSIONS: Men had higher odds of non-adherence and loss to follow-up than women. Potential interventions that might improve adherence in trial participants may include:targeting health education for men

    Full Text Available John M Mayer,1 James L Nuzzo,1 Simon Dagenais2 1School of Physical Therapy and Rehabilitation Sciences, College of Medicine, University of South Florida, Tampa, FL, 2Palladian Health, West Seneca, NY, USA Background: Firefighters are at increased risk for back injuries, which may be mitigated through exercise therapy to increase trunk muscle endurance. However, long-term adherence to exercise therapy is generally poor, limiting its potential benefits. Focus groups can be used to identify key barriers and facilitators to exercise adherence among study participants. Objective: To explore barriers and facilitators to worksite exercise therapy adherence among firefighters to inform future randomized controlled trials (RCTs. Methods: Participants enrolled in a previous RCT requiring twice-weekly worksite exercise therapy for 24 weeks were asked to take part in moderated focus group discussions centered on eight open-ended questions related to exercise adherence. Responses were analyzed qualitatively using a social ecological framework to identify key intrapersonal, interpersonal, and institutional barriers and potential facilitators to exercise adherence. Results: A total of 27 participants were included in the four focus group discussions, representing 50% of those assigned to a worksite exercise therapy group in the previous RCT, in which only 67% of scheduled exercise therapy sessions were completed. Lack of self-motivation was cited as the key intrapersonal barrier to adherence, while lack of peer support was the key interpersonal barrier reported, and lack of time to exercise during work shifts was the key institutional barrier identified. Conclusion: Focus group discussions identified both key barriers and potential facilitators to increase worksite exercise therapy adherence among firefighters. Future studies should consider educating and reminding participants about the benefits of exercise, providing individual and group incentives based on

    2008-04-01

    Full Text Available Abstract Background Although some interventions have been shown to improve adherence to medication for diabetes, results are not consistent. We have developed a theory-based intervention which we will evaluate in a well characterised population to test efficacy and guide future intervention development and trial design. Methods and Design The SAMS (Supported Adherence to Medication Study trial is a primary care based multi-centre randomised controlled trial among 200 patients with type 2 diabetes and an HbA1c of 7.5% or above. It is designed to evaluate the efficacy of a two-component motivational intervention based on the Theory of Planned Behaviour and volitional action planning to support medication adherence compared with standard care. The intervention is delivered by practice nurses. Nurses were trained using a workshop approach with role play and supervised using assessment of tape-recorded consultations. The trial has a two parallel groups design with an unbalanced three-to-two individual randomisation eight weeks after recruitment with twelve week follow-up. The primary outcome is medication adherence measured using an electronic medication monitor over 12 weeks and expressed as the difference between intervention and control in mean percentage of days on which the correct number of medication doses is taken. Subgroup analyses will explore impact of number of medications taken, age, HbA1c, and self-reported adherence at baseline on outcomes. The study also measures the effect of dispensing medication to trial participants packaged in the electronic medication-monitoring device compared with conventional medication packaging. This will be achieved through one-to-one randomisation at recruitment to these conditions with assessment of the difference between groups in self-report of medication adherence and change in mean HbA1c from baseline to eight weeks. Anonymised demographic data are collected on non-respondents. Central randomisation

    Full Text Available Treatment non-adherence results in treatment failure, prolonged transmission of disease and emergence of drug resistance. Although the problem widely investigated, there remains an information gap on the effectiveness of different methods to improve treatment adherence and the predictors of non-adherence in resource limited countries based on theoretical models. This study aimed to evaluate the impact of psychological counseling and educational intervention on tuberculosis (TB treatment adherence based on Health Belief Model (HBM.A cluster randomized control trial was conducted in Addis Ababa from May to December, 2014. Patients were enrolled into study consecutively from 30 randomly selected Health Centers (HCs (14 HCs intervention and 16 HCs control groups. A total of 698 TB patients, who were on treatment for one month to two months were enrolled. A structured questionnaire was administered to both groups of patients at baseline and endpoint of study. Control participants received routine directly-observed anti-TB therapy and the intervention group additionally received combined psychological counseling and adherence education. Treatment non-adherence level was the main outcome of the study, and multilevel logistic regression was employed to assess the impact of intervention on treatment adherence.At enrollment, the level of non-adherence among intervention (19.4% and control (19.6% groups was almost the same. However, after intervention, non-adherence level decreased among intervention group from 19.4 (at baseline to 9.5% (at endpoint, while it increased among control group from 19.4% (baseline to 25.4% (endpoint.

    Full Text Available PEARLS, a large scale trial of antiretroviral therapy (ART for HIV (n = 1,571, 9 countries, 4 continents, found that a once-daily protease inhibitor (PI based regimen (ATV+DDI+FTC, but not a once-daily non-nucleoside reverse transcriptase inhibitor/nucleoside reverse transcriptase inhibitor (NNRTI/NRTI regimen (EFV+FTC/TDF, had inferior efficacy compared to a standard of care twice-daily NNRTI/NRTI regimen (EFV+3TC/ZDV. The present study examined non-adherence in PEARLS.Outcomes: non-adherence assessed by pill count and by self-report, and time to treatment failure. Longitudinal predictors: regimen, quality of life (general health perceptions  =  QOL-health, mental health  =  QOL-mental health, social support, substance use, binge drinking, and sexual behaviors. "Life-Steps" adherence counseling was provided.In both pill-count and self-report multivariable models, both once-a-day regimens had lower levels of non-adherence than the twice-a-day standard of care regimen; although these associations attenuated with time in the self-report model. In both multivariable models, hard-drug use was associated with non-adherence, living in Africa and better QOL-health were associated with less non-adherence. According to pill-count, unprotected sex was associated with non-adherence. According to self-report, soft-drug use was associated with non-adherence and living in Asia was associated with less non-adherence. Both pill-count (HR = 1.55, 95% CI: 1.15, 2.09, p<.01 and self-report (HR = 1.13, 95% CI: 1.08, 1.13, p<.01 non-adherence were significant predictors of treatment failure over 72 weeks.

    Research has identified several communication strategies that could increase adherence to colorectal cancer screening recommendations. Two promising strategies are tailoring and narrative-based approaches. Tailoring is the personalization of information based on individual characteristics. Narrative-based approaches use stories about similar others to counter perceived barriers and cultivate self-efficacy. To compare these two approaches, a randomized controlled trial was carried out at 8 worksites in Indiana. Adults 50-75 (N = 209) received one of four messages about colorectal cancer screening: stock, narrative, tailored, tailored narrative. The primary outcome was whether participants filed a colonoscopy claim in the 18 months following the intervention. Individuals receiving narrative messages were 4 times more likely to screen than those not receiving narrative messages. Tailoring did not increase screening behavior overall. However, individuals with higher cancer information overload were 8 times more likely to screen if they received tailored messages. The results suggest that narrative-based approaches are more effective than tailoring at increasing colorectal cancer screening in worksite interventions. Tailoring may be valuable as a strategy for reaching individuals with high overload, perhaps as a follow-up effort to a larger communication campaign.

Adherence to clinical trial products and procedures is dependent on the motivations that drive participants. Data are presented to document reasons for trial participation and adherence to daily aciclovir for HSV-2 and HIV-1 genital shedding suppression among 300 HIV-1/HSV-2 seropositive women in South Africa. In-depth interviews after exit from the trial with 31 randomly selected women stratified by age and time since HIV diagnosis confirmed high levels of adherence measured during the trial. Main reasons for trial participation were related to seeking high-quality health care, which explains high levels of adherence in both study arms. Concerns that women would abuse reimbursements, fabricate data, and share or dump pills were not corroborated. Altruism is not a primary motivator in these settings where access to quality services is an issue. This study provides further evidence that good adherence of daily medication is possible in developing countries, particularly where study activities resonate with participants or fill an unmet need.Keywords: adherence, trial, HIV prevention, South Africa

    Full Text Available Abstract Background Failure to take medication reduces the effectiveness of treatment leading to increased morbidity and mortality. We evaluated the efficacy of a consultation-based intervention to support objectively-assessed adherence to oral glucose lowering medication (OGLM compared to usual care among people with type 2 diabetes. Methods This was a parallel group randomised trial in adult patients with type 2 diabetes and HbA1c≥7.5% (58 mmol/mol, prescribed at least one OGLM. Participants were allocated to a clinic nurse delivered, innovative consultation-based intervention to strengthen patient motivation to take OGLM regularly and support medicine taking through action-plans, or to usual care. The primary outcome was the percentage of days on which the prescribed dose of medication was taken, measured objectively over 12 weeks with an electronic medication-monitoring device (TrackCap, Aardex, Switzerland. The primary analysis was intention-to-treat. Results 211 patients were randomised between July 1, 2006 and November 30, 2008 in 13 British general practices (primary care clinics. Primary outcome data were available for 194 participants (91.9%. Mean (sd percentage of adherent days was 77.4% (26.3 in the intervention group and 69.0% (30.8 in standard care (mean difference between groups 8.4%, 95% confidence interval 0.2% to 16.7%, p = 0.044. There was no significant adverse impact on functional status or treatment satisfaction. Conclusions This well-specified, theory based intervention delivered in a single session of 30 min in primary care increased objectively measured medication adherence, with no adverse effect on treatment satisfaction. These findings justify a definitive trial of this approach to improving medication adherence over a longer period of time, with clinical and cost-effectiveness outcomes to inform clinical practice.

    Objective To develop a psychotherapy rating scale to measure therapist adherence in the Strong Without Anorexia Nervosa (SWAN) study, a multi-center randomized controlled trial comparing three different psychological treatments for adults with anorexia nervosa. The three treatments under investigation were Enhanced Cognitive Behavioural Therapy (CBT-E), the Maudsley Anorexia Nervosa Treatment for Adults (MANTRA), and Specialist Supportive Clinical Management (SSCM). Method The SWAN Psychotherapy Rating Scale (SWAN-PRS) was developed, after consultation with the developers of the treatments, and refined. Using the SWAN-PRS, two independent raters initially rated 48 audiotapes of treatment sessions to yield inter-rater reliability data. One rater proceeded to rate a total of 98 audiotapes from 64 trial participants. Results The SWAN-PRS demonstrated sound psychometric properties, and was considered a reliable measure of therapist adherence. The three treatments were highly distinguishable by independent raters, with therapists demonstrating significantly more behaviors consistent with the actual allocated treatment compared to the other two treatment modalities. There were no significant site differences in therapist adherence observed. Discussion The findings provide support for the internal validity of the SWAN study. The SWAN-PRS was deemed suitable for use in other trials involving CBT-E, MANTRA, or SSCM. © 2015 The Authors. International Journal of Eating Disorders Published by Wiley Periodicals, Inc.

    2017-01-01

    Background Physical activity (PA) can be assessed by accelerometer monitors. However, a high adherence to wearing this device is essential to obtain valid data. In this study, the influence of different wearing schemes and additional supportive phone calls (SPCs) on adherence was examined. Methods A randomized study with four groups was conducted in the context of a health examination program among participants aged 40–75 years without a history of cardiovascular diseases. Participants were recruited in different settings (general medical practices, job center, and health insurance). The participants were asked to wear an accelerometer for 7 consecutive days according to the wearing scheme “day and night” or “day only” and received or did not receive SPCs. Full adherence was defined as a total wearing time of 98 hours (between 8 am and 10 pm during 7 days). A generalized linear model was used to calculate the difference between the maximum possible and the observed adherence. Results Adherence could be assessed for 249 participants (mean age: 56.40 years; standard deviation [SD] 9.83, 40% males). The mean wearing time was 84.04 hours (SD 20.75). Participants with the wearing scheme day and night were significantly more adherent than participants with the wearing scheme day only (incidence rate ratio [IRR] 0.63; P=0.005). SPCs had no additional effect on adherence (IRR 0.80; P=0.168). Conclusion To assess PA, the wearing scheme day and night provides the best possible adherence in this group of participants. Further studies are necessary to examine adherence and the effects of additional SPCs in other samples or settings.

  20. The impact of monitoring on adherence and persistence with antiresorptive treatment for postmenopausal osteoporosis: a randomized controlled trial.

    Clowes, Jackie A; Peel, Nicola F A; Eastell, Richard

    2004-03-01

    Long-term adherence and persistence with any therapy are very poor ( approximately 50%). Adherence to therapy is defined as the percentage of prescribed medication taken, and persistence is defined as continuing to take prescribed medication. We examined whether monitoring by nursing staff could enhance adherence and persistence with antiresorptive therapy and whether presenting information on response to therapy provided additional benefit. In addition we evaluated the impact of monitoring on treatment efficacy. Seventy-five postmenopausal women with osteopenia were randomized to 1) no monitoring, 2) nurse-monitoring, or 3) marker-monitoring. All subjects were prescribed raloxifene. At 12, 24, and 36 wk, the nursing staff reviewed subjects in the monitored (nurse-monitoring or marker-monitoring) groups using a predefined protocol. The marker-monitored group were also presented a graph of response to therapy using percentage change in urinary N-telopeptide of type I collagen (uNTX), a bone resorption marker, at each visit. Biological response to therapy at 1 yr was determined using the percent change in bone mineral density (BMD) and uNTX. Treatment adherence and persistence were assessed using electronic monitoring devices. Survival analysis showed that the monitored group increased cumulative adherence to therapy by 57% compared with no monitoring (P = 0.04). There was a trend for the monitored group to persist with therapy for 25% longer compared with no monitoring (P = 0.07). Marker measurements did not improve adherence or persistence to therapy compared with nurse-monitoring alone. Adherence at 1 yr was correlated with percent change in hip (BMD) (r = 0.28; P = 0.01) and percent change in uNTX (r = -0.36; P = 0.002). In conclusion, monitoring of patients increased adherence to therapy by 57% at 1 yr. Increased adherence to therapy increased the effectiveness of raloxifene therapy determined using surrogate end points.

  1. Exercise and Motor Training in People with Parkinson's Disease: A Systematic Review of Participant Characteristics, Intervention Delivery, Retention Rates, Adherence, and Adverse Events in Clinical Trials

    2012-01-01

    Full Text Available There is research evidence that exercise and motor training are beneficial for people with Parkinson's disease (PD, and clinicians seek to implement optimal programs. This paper summarizes important factors about the nature and reporting of randomized controlled trials of exercise and/or motor training for people with PD which are likely to influence the translation of research into clinical practice. Searches identified 53 relevant trials with 90 interventions conducted for an average duration of 8.3 (SD 4.2 weeks. Most interventions were fully supervised (74% and conducted at a facility (79%. Retention rates were high with 69% of interventions retaining ≥85% of their participants; however adherence was infrequently reported, and 72% of trials did not report adverse events. Overall, the labor-intensive nature of most interventions tested in these trials and the sparse reporting of adherence and adverse events are likely to pose difficulties for therapists attempting to balance benefits and costs when selecting protocols that translate to sustainable clinical practice for people with PD.

This study tested the hypothesis that blacks exhibiting EDS would have poorer self-reported adherence to hypertensive medication using cross-sectional data from the Counseling African-Americans to Control Hypertension (CAATCH trial. Methods: A total of 1,058 hypertensive blacks (average age 57±12 years participated in CAATCH, a randomized controlled trial evaluating the effectiveness of a multilevel intervention for participants who receive care from community health centers in New York City. Data analyzed in this study included baseline sociodemographics, medical history, EDS, and medication adherence. We used the Epworth Sleepiness Scale, with a cutoff score of ≥10, to define EDS. Medication adherence was measured using an abbreviated Morisky Medication Adherence scale, with a score >0 indicating nonadherence. Results: Of the sample, 71% were female, 72% received at least a high school education, 51% reported a history of smoking, and 33% had a history of alcohol consumption. Overall, 27% of the participants exhibited EDS, and 44% of those who exhibited EDS were classified as adherent to prescribed antihypertensive medications. Multivariable logistic regression analysis, adjusting for effects of age, body mass index, sex, education, and smoking and drinking history indicated that participants who exhibited EDS were more than twice as likely to be nonadherent (odds ratio 2.28, 95

  3. Strong relationship between oral dose and tenofovir hair levels in a randomized trial: hair as a potential adherence measure for pre-exposure prophylaxis (PrEP.

    Albert Y Liu

    Full Text Available Pre-exposure prophylaxis (PrEP trials using tenofovir-based regimens have demonstrated that high levels of adherence are required to evaluate efficacy; the incorporation of objective biomarkers of adherence in trial design has been essential to interpretation, given the inaccuracy of self-report. Antiretroviral measurements in scalp hair have been useful as a marker of long-term exposure in the HIV treatment setting, and hair samples are relatively easy and inexpensive to collect, transport, and store for analysis. To evaluate the relationship between dose and tenofovir concentrations in hair, we examined the dose proportionality of tenofovir in hair in healthy, HIV-uninfected adults.A phase I, crossover pharmacokinetic study was performed in 24 HIV-negative adults receiving directly-observed oral tenofovir tablets administered 2, 4, and 7 doses/week for 6 weeks, with a ≥3-week break between periods. Small samples of hair were collected after each six-week period and analyzed for tenofovir concentrations. Geometric-mean-ratios compared levels between each pair of dosing conditions. Intensive plasma pharmacokinetic studies were performed during the daily-dosing period to calculate areas-under-the-time-concentration curves (AUCs.Over 90% of doses were observed per protocol. Median tenofovir concentrations in hair increased monotonically with dose. A log-linear relationship was seen between dose and hair levels, with an estimated 76% (95% CI 60-93% increase in hair level per 2-fold dose increase. Tenofovir plasma AUCs modestly predicted drug concentrations in hair.This study found a strong linear relationship between frequency of dosing and tenofovir levels in scalp hair. The analysis of quantitative drug levels in hair has the potential to improve adherence measurement in the PrEP field and may be helpful in determining exposure thresholds for protection and explaining failures in PrEP trials. Hair measures for adherence monitoring may also

    Antoine, Sunya-Lee; Pieper, Dawid; Mathes, Tim; Eikermann, Michaela

    2014-01-01

    Background Oral medication for patients with type 2 diabetes mellitus plays an important role in diabetes care and is associated with a high level self-care behavior and self-management. However, poor adherence to diabetes treatment is common which causes severe health complications and increased mortality. Barriers to adherence may consist of complex treatment regimens often along with long-term multi-therapies, side effects due to the medication as well as insufficient, incomprehensible or ...

Motivational interviewing (MI is a client-centered communication style that focuses on enhancing intrinsic motivation to engage in appropriate self-management behaviors. MI has been shown to improve a variety of health behaviors including medication adherence in other disorders, but its efficacy for the improvement of ICS adherence in asthmatics has yet to be examined. This pilot “proof of concept” trial assessed the feasibility of MI to improve daily ICS adherence and asthma control levels in adult asthmatics.Methods: Fifty-four poorly controlled (Asthma Control Questionnaire [ACQ] score ≥1.5, highly nonadherent (filled <50% of ICS medication in the last year adult asthmatics were recruited from the outpatient asthma clinic of a university-affiliated hospital.

    Adolescents with acute lymphoblastic leukemia (ALL) develop osteopenia early in therapy, potentially exacerbated by high rates of concurrent Vitamin D deficiency. We conducted a randomized clinical trial testing a Vitamin D-based intervention to improve Vitamin D status and reduce bone density decline. Poor adherence to home supplementation necessitated a change to directly observed therapy (DOT) with intermittent, high-dose Vitamin D3 randomized versus standard of care (SOC). Compared to SOC, DOT Vitamin D3 successfully increased trough Vitamin 25(OH)D levels (p = .026) with no residual Vitamin D deficiency, 100% adherence to DOT Vitamin D3, and without associated toxicity. However, neither Vitamin D status nor supplementation impacted bone density. Thus, this adherence-optimized intervention is feasible and effective to correct Vitamin D deficiency in adolescents during ALL therapy. Repletion of Vitamin D and calcium alone did not mitigate osteopenia, however, and new, comprehensive approaches are needed to address treatment-associated osteopenia during ALL therapy.

    We evaluated the feasibility and acceptability of a novel, 12-week, adjunctive, smartphone-assisted intervention to improve treatment adherence in bipolar disorder. Eight participants completed 4 in-person individual therapy sessions over the course of a month, followed by 60 days of twice-daily ecological momentary intervention (EMI) sessions, with a fifth in-person session after 30 days and a sixth in-person session after 60 days. Perceived credibility of the intervention and expectancy for change were adequate at baseline, and satisfaction on completion of the intervention was very high. Participants demonstrated good adherence to the intervention overall, including excellent adherence to the in-person component and fair adherence to the smartphone-facilitated component. Qualitative feedback revealed very high satisfaction with the in-person sessions and suggested a broad range of ways in which the EMI sessions were helpful. Participants also provided suggestions for improving the intervention, which primarily related to the structure and administration of the EMI (smartphone-administered) sessions. Although this study was not designed to evaluate treatment efficacy, most key outcome variables changed in the expected directions from pretreatment to posttreatment, and several variables changed significantly over the course of the in-person sessions or during the EMI phase. These findings add to the small but growing body of literature suggesting that EMIs are feasible and acceptable for use in populations with bipolar disorder.

    2016-01-01

    Background We assessed the effect of automated treatment adherence support delivered via mobile-phone short message system (SMS) text-messages on blood pressure. Methods and Results In this pragmatic single-blind, three-arm randomized trial (StAR), undertaken in South Africa, patients treated for high blood pressure were randomly allocated in a 1:1:1 ratio to information-only or interactive SMS text-messaging, or usual care. The primary outcome was change in systolic blood pressure at 12-months from baseline measured with a validated oscillometric device. All trial staff were masked to treatment allocation. Analyses were intention to treat. Between June 26, 2012 and November 23, 2012, 1372 participants were randomized to receive information-only SMS text-messages (n=457), interactive SMS text-messages (n=458), or usual care (n=457). Primary outcome data were available for 1256 (92%) participants. At 12-months, the mean adjusted change (95% CI) in systolic blood pressure compared to usual care was −2.2 mm Hg (−4.4 to −0.04) with information-only SMS and −1.6 mm Hg (−3.7 to 0.6) with interactive SMS. Odds ratios (95% CI) for the proportion of participants with a blood pressure <140/90mm Hg were for information-only messaging 1.42 (1.03 to 1.95) and for interactive messaging 1.41 (1.02 to 1.95) compared to usual care. Conclusions In this randomized trial of an automated adherence support program delivered by SMS text-message in a general outpatient population of adults with high blood pressure, we found a small, reduction in systolic blood pressure control compared to usual care at 12-months. There was no evidence that an interactive intervention increased this effect. Clinical Trial Registration Information ClinicalTrials.gov.

    2016-01-01

    Objective: To evaluate the safety and pharmacokinetics of MIV-150 and zinc acetate in a carrageenan gel (PC-1005). Acceptability, adherence, and pharmacodynamics were also explored. Design: A 3-day open-label safety run-in (n = 5) preceded a placebo-controlled, double-blind trial in healthy, HIV-negative, abstinent women randomized (4:1) to vaginally apply 4 mL of PC-1005 or placebo once daily for 14 days. Methods: Assessments included physical examinations, safety labs, colposcopy, biopsies, cervicovaginal lavages (CVLs), and behavioral questionnaires. MIV-150 (plasma, CVL, tissue), zinc (plasma, CVL), and carrageenan (CVL) concentrations were determined with LC-MS/MS, ICP-MS, and ELISA, respectively. CVL antiviral activity was measured using cell-based assays. Safety, acceptability, and adherence were analyzed descriptively. Pharmacokinetic parameters were calculated using noncompartmental techniques and actual sampling times. CVL antiviral EC50 values were calculated using a dose–response inhibition analysis. Results: Participants (n = 20) ranged from 19–44 years old; 52% were black or African American. Among those completing the trial (13/17, PC-1005; 3/3, placebo), 11/17 reported liking the gel overall; 7 recommended reducing the volume. Adverse events, which were primarily mild and/or unrelated, were comparable between groups. Low systemic MIV-150 levels were observed, without accumulation. Plasma zinc levels were unchanged from baseline. Seven of seven CVLs collected 4-hour postdose demonstrated antiviral (HIV, human papillomavirus) activity. High baseline CVL anti–herpes-simplex virus type-2 (HSV-2) activity precluded assessment of postdose activity. Conclusions: PC-1005 used vaginally for 14 days was well tolerated. Low systemic levels of MIV-150 were observed. Plasma zinc levels were unchanged. Postdose CVLs had anti-HIV and anti–human papillomavirus activity. These data warrant further development of PC-1005 for HIV and sexually transmitted

  16. A Systematic Review of Ebola Treatment Trials to Assess the Extent to Which They Adhere to Ethical Guidelines

    2017-01-01

    Background Objective: To determine to what extent each trial met criteria specified in three research frameworks for ethical trial conduct. Design: Systematic review and narrative analysis Methods and findings Data sources: MEDBASE and EMBASE databases were searched using a specific search strategy. The Cochrane database for systematic reviews, the PROSPERO database and trial registries were examined. A grey literature search and citation search were also carried out. Eligibility criteria for selecting studies: Studies were included where the intervention was being used to treat Ebola in human subjects regardless of study design, comparator or outcome measured. Studies were eligible if they had taken place after the 21st March 2014. Unpublished as well as published studies were included. Included studies: Sixteen studies were included in the data synthesis. Data was extracted on study characteristics as well as any information relating to ten ethical areas of interest specified in the three research frameworks for ethical trial conduct and an additional criterion of whether the study received ethics approval from a research ethics committee. Synthesis of results: Eight studies were judged to fully comply with all eleven criteria. The other eight studies all had at least one criteria where there was not enough information available to draw any conclusions. In two studies there were ethical concerns regarding the information provided in relation to at least one ethical criteria. Description of the effect: One study did not receive ethical approval as the authors argued that treating approximately one hundred patients consecutively for compassionate reasons did not constitute a clinical trial. Furthermore, after the patients were treated, physicians in Sierra Leone did not release reports of treatment results and so study conclusions had to be made based on unpublished observations. In another study the risk-benefit ratio of the trial drug does not appear to be

  17. A randomized clinical trial of a peri-operative behavioral intervention to improve physical activity adherence and functional outcomes following total knee replacement

    Zheng Hua

    2011-10-01

    Full Text Available Abstract Background Total knee replacement (TKR is a common and effective surgical procedure to relieve advanced knee arthritis that persists despite comprehensive medical treatment. Although TKR has excellent technical outcomes, significant variation in patient-reported functional improvement post-TKR exists. Evidence suggests that consistent post-TKR exercise and physical activity is associated with functional gain, and that this relationship is influenced by emotional health. The increasing use of TKR in the aging US population makes it critical to find strategies that maximize functional outcomes. Methods/Design This randomized clinical trial (RCT will test the efficacy of a theory-based telephone-delivered Patient Self-Management Support intervention that seeks to enhance adherence to independent exercise and activity among post- TKR patients. The intervention consists of 12 sessions, which begin prior to surgery and continue for approximately 9 weeks post-TKR. The intervention condition will be compared to a usual care control condition using a randomized design and a probabilistic sample of men and women. Assessments are conducted at baseline, eight weeks, and six- and twelve- months. The project is being conducted at a large healthcare system in Massachusetts. The study was designed to provide greater than 80% power for detecting a difference of 4 points in physical function (SF36/Physical Component Score between conditions (standard deviation of 10 at six months with secondary outcomes collected at one year, assuming a loss to follow up rate of no more than 15%. Discussion As TKR use expands, it is important to develop methods to identify patients at risk for sub-optimal functional outcome and to effectively intervene with the goal of optimizing functional outcomes. If shown efficacious, this peri-TKR intervention has the potential to change the paradigm for successful post-TKR care. We hypothesize that Patient Self-Management Support

    Matos Margarida G

    2008-07-01

    Full Text Available Abstract Background Research on the motivational model proposed by Self-Determination Theory (SDT provides theoretically sound insights into reasons why people adopt and maintain exercise and other health behaviors, and allows for a meaningful analysis of the motivational processes involved in behavioral self-regulation. Although obesity is notoriously difficult to reverse and its recidivism is high, adopting and maintaining a physically active lifestyle is arguably the most effective strategy to counteract it in the long-term. The purposes of this study are twofold: i to describe a 3-year randomized controlled trial (RCT aimed at testing a novel obesity treatment program based on SDT, and ii to present the rationale behind SDT's utility in facilitating and explaining health behavior change, especially physical activity/exercise, during obesity treatment. Methods Study design, recruitment, inclusion criteria, measurements, and a detailed description of the intervention (general format, goals for the participants, intervention curriculum, and main SDT strategies are presented. The intervention consists of a 1-year group behavioral program for overweight and moderately obese women, aged 25 to 50 (and pre-menopausal, recruited from the community at large through media advertisement. Participants in the intervention group meet weekly or bi-weekly with a multidisciplinary intervention team (30 2 h sessions in total, and go through a program covering most topics considered critical for successful weight control. These topics and especially their delivery were adapted to comply with SDT and Motivational Interviewing guidelines. Comparison group receive a general health education curriculum. After the program, all subjects are follow-up for a period of 2 years. Discussion Results from this RCT will contribute to a better understanding of how motivational characteristics, particularly those related to physical activity/exercise behavioral self

  19. Protocol for a Randomized Controlled Trial Evaluating Mobile Text Messaging to Promote Retention and Adherence to Antiretroviral Therapy for People Living With HIV in Burkina Faso

    Ouedraogo, Denis; Artavia-Mora, Luis; Bedi, Arjun; Thiombiano, Boundia Alexandre

    2016-01-01

    Background Retention in care and adherence to antiretroviral therapy (ART) among people living with human immunodeficiency virus (PLHIV) is a critical challenge in many African countries including Burkina Faso. Delivering text messaging (short message service, SMS) interventions through mobile phones may help facilitate health service delivery and improve patient health. Despite this potential, no evaluations have been delivered for national scale settings to demonstrate the impact of mobile health (mHealth) for PLHIV. Objectives This study aims to test the impact of SMS text messaging reminders for PLHIV in Burkina Faso, who are under ART. The evaluation identifies whether patients who receive SMS text messages are more likely to (1) retain in care (measured as a dichotomous variable), (2) adhere to antiretroviral regimens (measured as the number of doses missed in the past 7 days), and (3) experience slower disease progression (measured with T-lymphocytes cells). The second objective is to assess its effects on the frequency of health center visits, physical and psychosocial health, nutrition and whether the type of message (text vs image) and frequency (weekly vs semiweekly) have differential impacts including the possibility of message fatigue over time. Methods This 24-month, wide-scale intervention implements a randomized controlled trial (RCT) to evaluate the impact of four variants of a mHealth intervention versus a control group. Our sample comprises adult patients (>15 years of age) undergoing antiretroviral therapy with access to mobile phone services. Multivariate regression analysis will be used to analyze the effect of the intervention on the study population. Data collection is done at baseline and three follow-up waves 6, 12, and 24 months after the intervention starts. Results The targeted 3800 patients were recruited between February 2015 and May 2015. But political uncertainty delayed the launch of the intervention until October 2015. Data

  20. Adherence as a language game.

    Kolberg, Espen Skarstein

    2017-03-02

    Non-adherence, i.e. medication intake behavior not corresponding with agreed recommendations, is associated with increased morbidity and death, and it has been estimated that as many as 50% of patients in developed countries are not taking their medications as prescribed. But even as efforts in improving medication adherence over the years have increased, results are inconsistent, with only a minority of clinical trials showing any improvement in both adherence and clinical outcome. Since patient education is central to promoting good medication adherence, and language is integral to education, perhaps an exploration of the meaning and use of language, using the philosophy of Ludwig Wittgenstein, is in order.

  1. A MULTI-CENTER CLUSTER-RANDOMIZED TRIAL OF A MULTI-FACTORIAL INTERVENTION TO IMPROVE ANTIHYPERTENSIVE MEDICATION ADHERENCE AND BLOOD PRESSURE CONTROL AMONG PATIENTS AT HIGH CARDIOVASCULAR RISK (The COM99 study)*

    Pladevall, Manel; Brotons, Carlos; Gabriel, Rafael; Arnau, Anna; Suarez, Carmen; de la Figuera, Mariano; Marquez, Emilio; Coca, Antonio; Sobrino, Javier; Divine, George; Heisler, Michele; Williams, L Keoki

    2010-01-01

    Background Medication non-adherence is common and results in preventable disease complications. This study assesses the effectiveness of a multifactorial intervention to improve both medication adherence and blood pressure control and to reduce cardiovascular events. Methods and Results In this multi-center, cluster-randomized trial, physicians from hospital-based hypertension clinics and primary care centers across Spain were randomized to receive and provide the intervention to their high-risk patients. Eligible patients were ≥50 years of age, had uncontrolled hypertension, and had an estimated 10-year cardiovascular risk greater than 30%. Physicians randomized to the intervention group counted patients’ pills, designated a family member to support adherence behavior, and provided educational information to patients. The primary outcome was blood pressure control at 6 months. Secondary outcomes included both medication adherence and a composite end-point of all cause mortality and cardiovascular-related hospitalizations. Seventy-nine physicians and 877 patients participated in the trial. The mean duration of follow-up was 39 months. Intervention patients were less likely to have an uncontrolled systolic blood pressure (odds ratio 0.62; 95% confidence interval [CI] 0.50–0.78) and were more likely to be adherent (OR 1.91; 95% CI 1.19–3.05) when compared with control group patients at 6 months. After five years 16% of the patients in the intervention group and 19% in the control group met the composite end-point (hazard ratio 0.97; 95% CI 0.67–1.39). Conclusions A multifactorial intervention to improve adherence to antihypertensive medication was effective in improving both adherence and blood pressure control, but it did not appear to improve long-term cardiovascular events.

  3. Improving medication adherence in diabetes type 2 patients through Real Time Medication Monitoring: a Randomised Controlled Trial to evaluate the effect of monitoring patients' medication use combined with short message service (SMS reminders

    Bouvy Marcel L

    2011-01-01

    Full Text Available Abstract Background Innovative approaches are needed to support patients' adherence to drug therapy. The Real Time Medication Monitoring (RTMM system offers real time monitoring of patients' medication use combined with short message service (SMS reminders if patients forget to take their medication. This combination of monitoring and tailored reminders provides opportunities to improve adherence. This article describes the design of an intervention study aimed at evaluating the effect of RTMM on adherence to oral antidiabetics. Methods/Design Randomised Controlled Trial (RCT with two intervention arms and one control arm involving diabetes type 2 patients with suboptimal levels of adherence to oral antidiabetics (less than 80% based on pharmacy refill data. Patients in the first intervention arm use RTMM including SMS reminders and a personal webpage where they can monitor their medication use. Patients in the second intervention arm use RTMM without SMS reminders or webpage access. Patients in the control arm are not exposed to any intervention. Patients are randomly assigned to one of the three arms. The intervention lasts for six months. Pharmacy refill data of all patients are available from 11 months before, until 11 months after the start of the intervention. Primary outcome measure is adherence to oral antidiabetics calculated from: 1 data collected with RTMM, as a percentage of medication taken as prescribed, and as percentage of medication taken within the correct time interval, 2 refill data, taking the number of days for which oral antidiabetics are dispensed during the study period divided by the total number of days of the study period. Differences in adherence between the intervention groups and control group are studied using refill data. Differences in adherence between the two intervention groups are studied using RTMM data. Discussion The intervention described in this article consists of providing RTMM to patients with

    2008-10-01

    Full Text Available Abstract Background Most quality improvement programs in diabetes care incorporate aspects of clinician education, performance feedback, patient education, care management, and diabetes care teams to support primary care physicians. Few studies have applied all of these dimensions to address clinical inertia. Aim To evaluate interventions to improve adherence to evidence-based guidelines for diabetes and reduce clinical inertia in primary care physicians. Design Two-arm cluster randomized controlled trial. Participants Primary care physicians in Belgium. Interventions Primary care physicians will be randomly allocated to 'Usual' (UQIP or 'Advanced' (AQIP Quality Improvement Programs. Physicians in the UQIP will receive interventions addressing the main physician, patient, and office system factors that contribute to clinical inertia. Physicians in the AQIP will receive additional interventions that focus on sustainable behavior changes in patients and providers. Outcomes Primary endpoints are the proportions of patients within targets for three clinical outcomes: 1 glycosylated hemoglobin Primary and secondary analysis Statistical analyses will be performed using an intent-to-treat approach with a multilevel model. Linear and generalized linear mixed models will be used to account for the clustered nature of the data, i.e., patients clustered withinimary care physicians, and repeated assessments clustered within patients. To compare patient characteristics at baseline and between the intervention arms, the generalized estimating equations (GEE approach will be used, taking the clustered nature of the data within physicians into account. We will also use the GEE approach to test for differences in evolution of the primary and secondary endpoints for all patients, and for patients in the two interventions arms, accounting for within-patient clustering. Trial Registration number: NTR 1369.

  5. Adherence to a Mediterranean-style diet and effects on cognition in adults: A qualitative evaluation of the systematic review of longitudinal and prospective trials

    Roy J Hardman

    2016-07-01

    Full Text Available The Mediterranean-style diet (MedDiet involves substantial intake of fruits, vegetables, and fish, and a lower consumption of dairy, red meat, and sugars. Over the past 15 years much empirical evidence supports the suggestion that a MedDiet may be beneficial with respect to reducing the incidence of cardiovascular disease, cancer, metabolic syndrome, and dementia. A number of cross-sectional studies that have examined the impact of MedDiet on cognition have yielded largely positive results. The objective of this review is to evaluate longitudinal and prospective trials to gain an understanding of how a MedDiet may impact cognitive processes over time. The included studies were aimed at improving cognition or minimizing of cognitive decline. Studies reviewed included assessments of dietary status using either a food frequency questionnaire or a food diary assessment. Eighteen articles meeting our inclusion criteria were subjected to systematic review. These revealed that higher adherence to a MedDiet is associated with slower rates of cognitive decline, reduced conversion to Alzheimer’s disease (AD and improvements in cognitive function. The specific cognitive domains that were found to benefit with improved Mediterranean Diet Score (MedDietS were memory (delayed recognition, long-term and working memory executive function, and visual constructs. The current review has also considered a number of methodological issues in making recommendations for future research. The utilisation of a dietary pattern such as the Mediterranean style diet will be essential as part of the armamentarium to maintain quality of life and reduce the potential social and economic burden of dementia.

  6. A pilot controlled trial to determine the feasibility, acceptability and effectiveness of a PAPA-based online intervention to address practical and perceptual barriers to medication adherence in Inflammatory Bowel Disease.

    Sarah Chapman

    2015-11-01

    The intervention was effective in addressing perceptual barriers to adherence, as well as having a positive impact on IBD-related illness perceptions: increasing treatment control beliefs, and reducing concerns and emotional response. Fewer episodes of non-adherence were reported in the Intervention Group compared to the Control Group. Satisfaction with information about IBD medication improved following the intervention. However, the number of reported practical barriers was similar between the Intervention and Control groups, suggesting that other support might need to be incorporated into the intervention. Limitations of this study include potential bias due to drop-out, potential lack of generalisability to patient populations not recruited online and a reliance on self-report rather than objective outcome measures. However, this controlled trial suggests that the IBD-Helper intervention may be an effective, feasible and acceptable method of addressing perceptual barriers to adherence.

    Novel ideas are needed to increase adherence to antihypertensive medication. The current study used data from the Counseling African Americans to Control Hypertension (CAATCH) study, a sample of 442 hypertensive African Americans, to investigate the mediating effects of expectation of hypertension care, social support, hypertension knowledge, and medication adherence, adjusting for age, sex, number of medications, diabetes, education, income, employment, insurance status, and intervention. Sixty-six percent of patients had an income of $20,000 or less and 56% had a high school education or less, with a mean age of 57 years. Greater expectation of care was associated with greater medication adherence (P=.007), and greater social support was also associated with greater medication adherence (P=.046). Analysis also showed that expectation of care mediated the relationship between hypertension knowledge and medication adherence (P<.05). Expectation of care and social support are important factors for developing interventions to increase medication adherence among blacks. PMID:26593105

    2012-06-01

    Full Text Available Abstract Background Physical activity and exercise therapy are among the accepted clinical rehabilitation guidelines and are recommended self-management strategies for chronic low back pain. However, many back pain sufferers do not adhere to their physiotherapist’s recommendations. Poor patient adherence may decrease the effectiveness of advice and home-based rehabilitation exercises. According to self-determination theory, support from health care practitioners can promote patients’ autonomous motivation and greater long-term behavioral persistence (e.g., adherence to physiotherapists’ recommendations. The aim of this trial is to assess the effect of an intervention designed to increase physiotherapists’ autonomy-supportive communication on low back pain patients’ adherence to physical activity and exercise therapy recommendations. Methods/Design This study will be a single-blinded cluster randomized controlled trial. Outpatient physiotherapy centers (N =12 in Dublin, Ireland (population = 1.25 million will be randomly assigned using a computer-generated algorithm to either the experimental or control arm. Physiotherapists in the experimental arm (two hospitals and four primary care clinics will attend eight hours of communication skills training. Training will include handouts, workbooks, video examples, role-play, and discussion designed to teach physiotherapists how to communicate in a manner that promotes autonomous patient motivation. Physiotherapists in the waitlist control arm (two hospitals and four primary care clinics will not receive this training. Participants (N = 292 with chronic low back pain will complete assessments at baseline, as well as 1 week, 4 weeks, 12 weeks, and 24 weeks after their first physiotherapy appointment. Primary outcomes will include adherence to physiotherapy recommendations, as well as low back pain, function, and well-being. Participants will be blinded to treatment allocation, as

    2010-08-01

    Full Text Available Abstract Background The Kanyini Guidelines Adherence with the Polypill (Kanyini-GAP Study aims to examine whether a polypill-based strategy (using a single capsule containing aspirin, a statin and two blood pressure-lowering agents amongst Indigenous and non-Indigenous people at high risk of experiencing a cardiovascular event will improve adherence to guideline-indicated therapies, and lower blood pressure and cholesterol levels. Methods/Design The study is an open, randomised, controlled, multi-centre trial involving 1000 participants at high risk of cardiovascular events recruited from mainstream general practices and Aboriginal Medical Services, followed for an average of 18 months. The participants will be randomised to one of two versions of the polypill, the version chosen by the treating health professional according to clinical features of the patient, or to usual care. The primary study outcomes will be changes, from baseline measures, in serum cholesterol and systolic blood pressure and self-reported current use of aspirin, a statin and at least two blood pressure lowering agents. Secondary study outcomes include cardiovascular events, renal outcomes, self-reported barriers to indicated therapy, prescription of indicated therapy, occurrence of serious adverse events and changes in quality-of-life. The trial will be supplemented by formal economic and process evaluations. Discussion The Kanyini-GAP trial will provide new evidence as to whether or not a polypill-based strategy improves adherence to effective cardiovascular medications amongst individuals in whom these treatments are indicated. Trial Registration This trial is registered with the Australian New Zealand Clinical Trial Registry ACTRN126080005833347.

    Concerns that standard didactic adherence counselling may be inadequate to maximise antiretroviral therapy (ART) adherence led us to evaluate more intensive individualised motivational adherence counselling. We randomised 297 HIV-positive ART-naïve patients in Durban, South Africa, to receive either didactic counselling, prior to ART initiation (n = 150), or an intensive motivational adherence intervention after initiating ART (n = 147). Study arms were similar for age (mean 35.8 years), sex (43.1 % male), CD4+ cell count (median 121.5 cells/μl) and viral load (median 119,000 copies/ml). Virologic suppression at 9 months was achieved in 89.8 % of didactic and 87.9 % of motivational counselling participants (risk ratio [RR] 0.98, 95 % confidence interval [CI] 0.90-1.07, p = 0.62). 82.9 % of didactic and 79.5 % of motivational counselling participants achieved >95 % adherence by pill count at 6 months (RR 0.96, 95 % CI 0.85-1.09, p = 0.51). Participants receiving intensive motivational counselling did not achieve higher treatment adherence or virological suppression than those receiving routinely provided didactic adherence counselling. These data are reassuring that less resource intensive didactic counselling was adequate for excellent treatment outcomes in this setting.

    Little research has investigated interventions to improve the delivery of counselling in health care settings. We determined the impact of training and supervision delivered as part of the Options: Western Cape project on lay antiretroviral adherence counsellors' practice. Four NGOs employing 39 adherence counsellors in the Western Cape were randomly allocated to receive 53 h of training and supervision in Options for Health, an intervention based on the approach of Motivational Interviewing. Five NGOs employing 52 adherence counsellors were randomly allocated to the standard care control condition. Counselling observations were analysed for 23 intervention and 32 control counsellors. Intervention counsellors' practice was more consistent with a client-centred approach than control counsellors', and significantly more intervention counsellors engaged in problem-solving barriers to adherence (91 vs. 41 %). The Options: Western Cape training and supervision package enabled lay counsellors to deliver counselling for behaviour change in a manner consistent with evidence-based approaches.

  15. Adherence as a predictor of sexual behaviors in people living with HIV/AIDS during the first year of antiretroviral therapy in rural Cameroon: data from Stratall ANRS 12110/ESTHER trial.

    Gilbert Ndziessi

    Full Text Available OBJECTIVE: This study aims to investigate the time pattern of inconsistence condom use (ICU during the first year of antiretroviral therapy (ART and its relationship with treatment adherence in naïve HIV-infected adult patients. METHODS: Data collection was nested within a longitudinal trial on HIV treatment. ICU was defined as reporting to have "never", "sometimes" or "nearly always" used condoms with one's main or casual partner(s--either HIV-negative or of unknown HIV status in the three previous months. Adherence was defined as taking 100% of their ART prescribed doses in the 4 days before the visit and "not having interrupted treatment", even once, for more than two consecutive days during the 4 previous weeks. Mixed logistic regression was used to study the relationship between adherence and ICU. RESULTS: Among the 459 patients enrolled, 212 (46% during 334 visits reported to have had sexual intercourse at least once with their partner(s--either HIV-negative or of unknown HIV status--during the first 12 months of ART. The proportion of ICU was 76%, 50% and 59% at month 0 (M0, month 6 (M6 and month 12 (M12, while 60% and 66% of patients were ART-adherent at M6 and M12, respectively. After adjustment for the frequency of sexual activity, type of sexual partner(s, perceived social class and desire for a child, patients adherent to ART were less likely to report ICU when compared with baseline (AOR [95% CI]: 0.38 [0.19-0.76]; P = 0.006. CONCLUSIONS: Adherence to ART is associated with a lower risk of ICU but this result needs to be interpreted carefully. As adherence behaviors are not only determined by problems with the healthcare systems but also by social barriers encountered by patients in their daily life, counseling should not only be ART adherence-centered but also patient-centered, including sexual risk minimization and psychosocial support.

  16. A randomized-controlled trial with a Canadian electronic pill dispenser used to measure and improve medication adherence in patients with schizophrenia

    Emmanuel eStip

    2013-08-01

    Full Text Available Objective: Medication adherence is extremely important in preventing relapse and lowering symptoms in schizophrenic patients. However, estimates show that nearly half of these patients have poor adherence. The Brief Adherence Rating Scale (BARS seems to be the most reliable tool assessing adherence in schizophrenia and shows that the antipsychotic adherence ratio (AAR is about 49.5 % in schizophrenia. The aim of the study was to test if an electronic pill dispenser named DoPill® improved AAR of schizophrenic patients. Furthermore, we compared AAR obtained by the DoPill® and the BARS, in order to verify whether the DoPill® provides reliable assessment of medication adherence. Methods: The DoPill® is a smart pill dispenser that beeps and flashes at the appropriate time of the day. Each of its 28 compartments is covered by a plastic lamina that, when taken off, sends a signal to the pharmacist. Patients were randomized to the DoPill® or Treatment As Usual group (TAU for six weeks. The BARS was used as a reference measure. Results: Forty-six percent of patients were deemed to be non-adherent with antipsychotic medication. The mean AAR was 67 % after six weeks. DoPill® recorded better AAR than some of those found in the literature and were lower than the BARS estimate we found. Conclusion: These results suggest that DoPill® is a valid tool that provides more reliable and objective data for the clinician about their patient’s adherence, than existing assessment tools like the BARS. Furthermore, the device may help patients successfully manage their medication regimen.

    2009-01-01

    Full Text Available Introduction. To enhance effective treatment, african nations including Ghana changed its malaria treatment policy from monotherapy to combination treatment with artesunate-amodiaquine (AS+AQ. The major challenge to its use in loose form is adherence. Objective. The objectives of this study were to investigate adherence and treatment outcome among patients treated with AS+AQ combination therapy for acute uncomplicated malaria. Methodology. The study was conducted in two rural districts located in the middle belt of Ghana using quantitative methods. Patients diagnosed with acute uncomplicated malaria as per the Ghana Ministry of Health malaria case definitions were randomly allocated to one of two groups. All patients in both groups were educated about the dose regimen of AS+AQ therapy and the need for adherence. Treatment with AS+AQ was supervised in one group while the other group was not supervised. Adherence was assessed by direct observation of the blister package of AS+AQ left on day 2. Results. 401 participants were randomized into the supervised (211 and unsupervised (190 groups. Compliance in both supervised (95.7% and unsupervised (92.6% groups were similar (P=.18. The commonest side-effects reported on day 2 among both groups were headaches, and body weakness. Parasite clearance by day 28 was >95% in both groups. Discussion/Conclusions. Administration of AS-AQ in both groups resulted in high levels of adherence to treatment regimen among adolescent and adult population in central Ghana. It appears that high level of adherence to AS-AQ is achievable through a rigorous education programme during routine clinic visits.

    2012-05-01

    Full Text Available Abstract Background In the US, Hispanic women have a higher incidence of, and mortality from, cervical cancer than non-Hispanic white women. The reason for this disparity may be attributable to both low rates of screening and poor adherence to recommended diagnostic follow-up after an abnormal Pap test. The 'Cervical Cancer Screening and Adherence to Follow-up Among Hispanic Women' study is a collaboration between a research institution and community partners made up of members from community based organizations, the Yakima Valley Farm Workers Clinic and the Breast, Cervical, and Colon Health Program of the Yakima District . The study will assess the efficacy of two culturally-appropriate, tailored educational programs designed to increase cervical cancer screening among Hispanic women, based in the Yakima Valley, Washington, US. Methods/design A parallel randomized-controlled trial of 600 Hispanic women aged 21–64, who are non-compliant with Papanicolau (Pap test screening guidelines. Participants will be randomized using block randomization to (1 a control arm (usual care; (2 a low-intensity information program, consisting of a Spanish-language video that educates women on the importance of cervical cancer screening; or (3 a high-intensity program consisting of the video plus a ‘promotora’ or lay-community health educator-led, home based intervention to encourage cervical cancer screening. Participants who attend cervical cancer screening, and receive a diagnosis of an abnormal Pap test will be assigned to a patient navigator who will provide support and information to promote adherence to follow-up tests, and any necessary surgery or treatment. Primary endpoint: Participants will be tracked via medical record review at community-based clinics, to identify women who have had a Pap test within 7 months of baseline assessment. Medical record reviewers will be blinded to randomization arm. Secondary endpoint: An evaluation of the patient

    Full Text Available Abstract Background Although the percentage of women who initiate breast cancer screening is rising, the rate of continued adherence is poor. The purpose of this study was to examine the effectiveness and cost-effectiveness of a tailored print intervention compared with a non-tailored print intervention for increasing the breast cancer screening rate among a non-adherent population. Methods In total, 1859 participants aged 51–59 years (except those aged 55 years were recruited from a Japanese urban community setting. Participants were randomly assigned to receive either a tailored print reminder (tailored intervention group or non-tailored print reminder (non-tailored intervention group. The primary outcome was improvement in the breast cancer screening rate. The screening rates and cost-effectiveness were examined for each treatment group (tailored vs. non-tailored and each intervention subgroup during a follow-up period of five months. All analyses followed the intention-to-treat principle. Results The number of women who underwent a screening mammogram following the reminder was 277 (19.9% in the tailored reminder group and 27 (5.8% in the non-tailored reminder group. A logistic regression model revealed that the odds of a woman who received a tailored print reminder undergoing mammography was 4.02 times those of a women who had received a non-tailored print reminder (95% confidence interval, 2.67–6.06. The cost of one mammography screening increase was 2,544 JPY or 30 USD in the tailored intervention group and 4,366 JPY or 52 USD in the non-tailored intervention group. Conclusions Providing a tailored print reminder was an effective and cost-effective strategy for improving breast cancer screening rates among non-adherent women.

  7. Improving patient adherence to lifestyle advice (IMPALA: a cluster-randomised controlled trial on the implementation of a nurse-led intervention for cardiovascular risk management in primary care (protocol

    Grol Richard

    2008-01-01

    Full Text Available Abstract Background Many patients at high risk of cardiovascular diseases are managed and monitored in general practice. Recommendations for cardiovascular risk management, including lifestyle change, are clearly described in the Dutch national guideline. Although lifestyle interventions, such as advice on diet, physical exercise, smoking and alcohol, have moderate, but potentially relevant effects in these patients, adherence to lifestyle advice in general practice is not optimal. The IMPALA study intends to improve adherence to lifestyle advice by involving patients in decision making on cardiovascular prevention by nurse-led clinics. The aim of this paper is to describe the design and methods of a study to evaluate an intervention aimed at involving patients in cardiovascular risk management. Methods A cluster-randomised controlled trial in 20 general practices, 10 practices in the intervention arm and 10 in the control arm, starting on October 2005. A total of 720 patients without existing cardiovascular diseases but eligible for cardiovascular risk assessment will be recruited. In both arms, the general practitioners and nurses will be trained to apply the national guideline for cardiovascular risk management. Nurses in the intervention arm will receive an extended training in risk assessment, risk communication, the use of a decision aid and adapted motivational interviewing. This communication technique will be used to support the shared decision-making process about risk reduction. The intervention comprises 2 consultations and 1 follow-up telephone call. The nurses in the control arm will give usual care after the risk estimation, according to the national guideline. Primary outcome measures are self-reported adherence to lifestyle advice and drug treatment. Secondary outcome measures are the patients' perception of risk and their motivation to change their behaviour. The measurements will take place at baseline and after 12 and 52

    Background The use of mobile phone apps for improving lifestyles has become generalized in the population, although little is still known about their effectiveness in improving health. Objective We evaluate the effect of adding an app to standard counseling on increased physical activity (PA) and adherence to the Mediterranean diet, 3 months after implementation. Methods A randomized, multicenter clinical trial was carried out. A total of 833 participants were recruited in six primary care centers in Spain through random sampling: 415 in the app+counseling group and 418 in the counseling only group. Counseling on PA and the Mediterranean diet was given to both groups. The app+counseling participants additionally received training in the use of an app designed to promote PA and the Mediterranean diet over a 3-month period. PA was measured with the 7-day Physical Activity Recall (PAR) questionnaire and an accelerometer; adherence to the Mediterranean diet was assessed using the Mediterranean Diet Adherence Screener questionnaire. Results Participants were predominantly female in both the app+counseling (249/415, 60.0%) and counseling only (268/418, 64.1%) groups, with a mean age of 51.4 (SD 12.1) and 52.3 (SD 12.0) years, respectively. Leisure-time moderate-to-vigorous physical activity (MVPA) by 7-day PAR increased in the app+counseling (mean 29, 95% CI 5-53 min/week; P=.02) but not in the counseling only group (mean 17.4, 95% CI –18 to 53 min/week; P=.38). No differences in increase of activity were found between the two groups. The accelerometer recorded a decrease in PA after 3 months in both groups: MVPA mean –55.3 (95% CI –75.8 to –34.9) min/week in app+counseling group and mean –30.1 (95% CI –51.8 to –8.4) min/week in counseling only group. Adherence to the Mediterranean diet increased in both groups (8.4% in app+counseling and 10.4% in counseling only group), with an increase in score of 0.42 and 0.53 points, respectively (P<.001), but no

METHOD: A randomized controlled trial with a 6-month follow-up period was performed in 70 adults, aged 45 years or older, with type 2 diabetes who were taking insulin and who had an HbA1c level ≥8%. Patients in the control group (CG (n = 36 received standard care, patients in the intervention group (IG (n = 34 received an individualized pharmacotherapeutic care plan and diabetes education. The primary outcome measure was change in HbA1c. Secondary outcomes included diabetes and medication knowledge, adherence to medication, insulin injection and home blood glucose monitoring techniques and diabetes-related quality of life. Outcomes were evaluated at baseline and 6 months using questionnaires. RESULTS: Diabetes knowledge, medication knowledge, adherence to medication and correct insulin injection and home blood glucose monitoring techniques significantly improved in the intervention group but remained unchanged in the control group. At the end of the study, mean HbA1c values in the control group remained unchanged but were significantly reduced in the intervention group. Diabetes-related quality of life significantly improved in the intervention group but worsened significantly in the control group. CONCLUSION: The program improved health outcomes and resulted in better glycemic control in patients with type 2 diabetes undergoing insulin therapy.

    Transition from child to adult-oriented care is widely regarded a challenging period for young people with kidney transplants and is associated with a high risk of graft failure. We analyzed the existing transition structures in Germany and Austria using a questionnaire and retrospective data of 119 patients transferred in 2011 to 2012. Most centers (73%) confirmed agreements on the transition procedure. Patients' age at transfer was subject to regulation in 73% (18 years). Median age at transition was 18.3 years (16.5-36.7). Median serum creatinine increased from 123 to 132 μmol/L over the 12 month observation period before transfer (P = 0.002). A total of 25/119 patients showed increased creatinine ≥ 20% just before transfer. Biopsy proven rejection was found in 10/119 patients. Three patients lost their graft due to chronic graft nephropathy.Mean coefficient of variation (CoV%) of immunosuppression levels was 0.20 ± 0.1. Increased creatinine levels ≥ 20% just before transfer were less frequently seen in patients with CoV < 0.20 (P = 0.007). The majority of pediatric nephrology centers have internal agreements on transitional care. More than half of the patients had CoV of immunosuppression trough levels consistent with good adherence. Although, 20% of the patients showed increase in serum creatinine close to transfer.

    Full Text Available Objectives: To evaluate the efficacy of a healthcare education program for patients with hypertension. Methods: A multicenter, prospective, cluster-randomized trial was conducted. Randomization was by primary care center; 18 of 36 urban primary care centers in Barcelona and its metropolitan area were randomized to the intervention group (IG and 18 to the control group (CG. The study sample consisted of patients with hypertension (n=996; 515 in the IG and 481 in the CG receiving outpatient treatment with antihypertensive drugs. The intervention consisted of personalized information by a trained nurse and written leaflets. Questionnaires on knowledge and awareness of hypertension and its medication, treatment adherence, healthy lifestyle habits, systolic and diastolic blood pressure, and body mass index were assessed at each visit, with a 12-month follow-up. An intention-to-treat analysis was applied. Results: Knowledge of hypertension increased by 27.8% in the IG and by 18.5% in the CG, while that of medication increased by 10.1% in the IG and 5.5% in the CG. Treatment adherence measured by the Morisky-Green test increased by 9.6% (95% CI: 5.5-13.6 in the IG and 8.8% (95% CI: 4.9-12.6 in the CG. There were no differences in adherence on the other tests used. No differences were observed between the IG and CG in clinical variables such as blood pressure or BMI at the end of the trial. Conclusions: The educational intervention had no significant impact on patients´ adherence to the medication.Objetivos: Evaluar la eficacia de un programa de educación sanitaria en pacientes con hipertensión.

    Full Text Available Mental Retardation (MR is a developmental disability characterized by impairments in adaptive daily life skills and difficulties in social and interpersonal functioning. Since multiple causes may contribute to MR, associated clinical pictures may vary accordingly. Nevertheless, when psychiatric disorders as Treatment Resistant Depression (TRD and/or alcohol abuse co-exist, their proper detection and management is often troublesome, essentially due to a limited vocabulary MR people could use to describe their symptoms, feelings and concerns, and the lack of reliable screening tools. Furthermore, MR people are among the most medicated subjects, with (over prescription of antidepressants and/or typical antipsychotics being the rule rather than exception. Thus, treatment resistance or even worsening of depression, constitute frequent occurrences. This report describes the case of a person with MR who failed to respond to repetitive trials of antidepressant monotherapies, finally recovering using aripiprazole to fluvoxamine augmentation upon consideration of a putative bipolar diathesis for “agitated” TRD. Although further controlled investigations are needed to assess a putative bipolar diathesis in some cases of MR associated to TRD, prudence is advised in the long-term prescription of antidepressant monotherapies in such conditions.

  16. Cluster-randomized non-inferiority trial to compare supplement consumption and adherence to different dosing regimens for antenatal calcium and iron-folic acid supplementation to prevent preeclampsia and anaemia: rationale and design of the Micronutrient Initiative study

    2015-11-01

    Full Text Available Background: To prevent pre-eclampsia in populations with insufficient dietary calcium (Ca intake, the World Health Organisation (WHO recommends routine Ca supplementation during antenatal care (ANC. WHO guidelines suggest a complex dosing regimen, requiring as many as 5 pill-taking events per day when combined with iron and folic acid (IFA supplements. Poor adherence may undermine public health effectiveness, so simpler regimens may be preferable. This trial will compare the effect of the WHO-recommended (higher-dose regimen vs. a simpler, lower-dose regimen on supplement consumption and pill-taking behaviours in Kenyan ANC clients. Design and methods: This is a parallel, non-inferiority, cluster-randomized trial; we examined 16 primary care health facilities in Kenya, 1047 pregnant women between 16-30 weeks gestational age. Higher-dose regimen: 1.5 g elemental calcium in 3 separate doses (500 mg Ca/pill and IFA (60 mg Fe + 400 μg folic acid taken with evening dose. Lower-dose regimen: 1.0 g calcium in 2 separate doses (500 mg Ca/pill with IFA taken as above. Measurements: Primary outcome is Ca pills consumed per day, measured by pill counts. Secondary outcomes include IFA pills consumed per day, client knowledge, motivation, social support, and satisfaction, measured at 4 to 10 weeks post-enrolment. Statistical analyses: Unit of randomization is the health-care facility; unit of analysis is individual client. Intent-to-treat analysis will be implemented with multi-level models to account for clustering. Expected public health impact: If pregnant women prescribed lower doses of Ca ingest as many pills as women prescribed the WHO-recommended regimen, developing a lower-dose recommendation for antenatal Ca and IFA supplementation programs could save resources.

  17. Adherence to antidepressants

    Full Text Available While major depression is considered a frequent mental illness there are ongoing reports of high non-adherence to antidepressant medications which places suffers at high risk for relapse, recurrence, or greater impairment,. The World Health Organization (WHO defines adherence as the extent to which a person′s behavior (e.g. taking medications can align with the agreed recommendations of a health care provider. Unfortunately while patient may recognize the importance of adherence to antidepressant medications the majority of patients do not adhere to their prescribed antidepressants. Some of the factors that may contribute to or lead to non-adherence include knowingly or unknowingly missing doses, taking extra doses, delaying administration times, or taking drug holidays. Pharmacists have the unique ability to deter non-adherence through the performance of continuous assessment and monitoring of adherence in this population given these accessibility. Additionally, pharmacists are able to develop therapeutic alliances with patients that can help to increase the likelihood of achieving positive patient outcomes. Antidepressant non-adherence can be viewed as a significant public health concern so it is important for patients to be educated about the importance of adherence, and health care professionals should be aware of factors or patient characteristics that can serve as barriers to non-adherence.

    Medication adherence rates strongly depend on favorable disease outcomes. It is known that medication adherence rates are lower for topical treatment than for systemic treatment. However, to date no validated instrument for the assessment of adherence factors in topical treatment is available. The aim of this study was to develop a new questionnaire to assess adherence risk factors in topical treatment. The development of the Topical Therapy Adherence Questionnaire (TTAQ) and Patient Preference Questionnaire (PPQ) was based on a systematic literature review, and qualitative patient focus interviews and expert focus groups' input. The psychometric properties and comprehensibility of the TTAQ and PPQ were assessed in a feasibility study with 59 psoriasis patients. Our first preliminary results indicate that the TTAQ and PPQ are psychometrically sound and reliable measures for the assessment of factors influencing topical treatment adherence. The questionnaires are currently being further developed and various parameters (e.g., time point of assessment) are currently being tested in an exploratory pilot study with ca. 2,000 psoriasis patients receiving topical treatment in a European clinical trial. The use of the final versions of TTAQ and PPQ in clinical practice may facilitate the early identification of specific non-adherence factors in patients under topical treatment, which could enable designing and applying adherence-enhancing interventions according to the patient's individual needs.

    Background To be consistent with the United Nations' sustainable development goals on gender equality, mobile health (mHealth) programmes should aim to use communications technology to promote the empowerment of women. We conducted a pre-trial analysis of data from the WelTel Retain study on retention in HIV care to assess gender-based differences in phone access, phone sharing and concerns about receiving text messages from a healthcare provider. Methods Between April 2013-June 2015, HIV-positive adults were screened for trial participation at two clinics in urban slums in Nairobi, Kenya. Proportions of men and women excluded from the trial due to phone-related criteria were compared using a chi-square test. Gender-based differences in phone sharing patterns and concerns among trial participants were similarly compared. Results Of 1068 individuals screened, there was no difference in the proportion of men ( n = 39/378, 10.3%) and women ( n = 71/690, 10.3%) excluded because of phone-related criteria ( p-value = 0.989). Among those who shared their phone, women ( n = 52/108, 48.1%) were more likely than men ( n = 6/60, 10.0%) to share with other non-household and household members ( p < 0.001). Few participants had concerns about receiving text messages from their healthcare provider; those with concerns were all women ( n = 6/700). Discussion In this study, men and women were equally able to participate in a trial of an mHealth intervention. Equitable access in these urban slums may indicate the 'gender digital divide' is narrowing in some settings; however, gender-specific phone sharing patterns and concerns regarding privacy must be fully considered in the development and scale-up of mHealth programmes.

An understanding of patient adherence and its modulating factors is necessary to correctly interpret treatment efficacy and barriers to therapeutic success.Purpose: This meta-analysis aims to systematically review published randomized controlled trials of reminder interventions to assist patient adherence to prescribed medications.Methods: A Medline search was performed for randomized controlled trials published between 1968 and June 2011, which studied the effect of reminder-based interventions on adherence to self-administered daily medications.Results: Eleven published randomized controlled trials were found between 1999 and 2009 which measured adherence to a daily medication in a group receiving reminder interventions compared to controls receiving no reminders. Medication adherence was measured as the number of doses taken compared to the number prescribed within a set period of time. Meta-analysis showed a statistically significant increase in adherence in groups receiving a reminder intervention compared to controls (66.61% versus 54.71%, 95% CI for mean: 0.8% to 22.4%. Self-reported and electronically monitored adherence rates did not significantly differ (68.04% versus 63.67%, P = 1.0. Eight of eleven studies showed a statistically significant increase in adherence for at least one of the reminder group arms compared to the control groups receiving no reminder intervention.Limitations: The data are limited by imperfect measures of adherence due to variability in data collection methods.

An accurate adherence index should therefore reflect treatment effectiveness, but the standard method of reporting adherence, that is, as a percentage of the agreed regimen between clinicians and people with cystic fibrosis, does not account for the appropriateness of the treatment regimen. We describe two different indices of inhaled therapy adherence for adults with cystic fibrosis which take into account effectiveness, that is, “simple” and “sophisticated” normative adherence. Methods to calculate normative adherence: Denominator adjustment involves fixing a minimum appropriate value based on the recommended therapy given a person’s characteristics. For simple normative adherence, the denominator is determined by the person’s Pseudomonas status. For sophisticated normative adherence, the denominator is determined by the person’s Pseudomonas status and history of pulmonary exacerbations over the previous year. Numerator adjustment involves capping the daily maximum inhaled therapy use at 100% so that medication overuse does not artificially inflate the adherence level. Three illustrative cases: Case A is an example of inhaled therapy under prescription based on Pseudomonas status resulting in lower simple normative adherence compared to unadjusted adherence. Case B is an example of inhaled therapy under-prescription based on previous exacerbation history resulting in lower sophisticated normative adherence compared to unadjusted adherence and simple normative adherence

    The primary objective of this review was to identify and examine the literature on the association between medication adherence self-reported questionnaires (SRQs) and medication monitoring devices. The primary literature search was performed for 1980-2009 using PubMed, PubMed In Process and Non-Indexed, Ovid MEDLINE, Ovid MEDLINE In-Process, PsycINFO (EBSCO), CINAHL (EBSCO), Ovid HealthStar, EMBASE (Elsevier) and Cochrane Databases and using the following search terms: 'patient compliance', 'medication adherence', 'treatment compliance', 'drug monitoring', 'drug therapy', 'electronic', 'digital', 'computer', 'monitor', 'monitoring', 'drug', 'drugs', 'pharmaceutical preparations', 'compliance' and 'medications'. We identified studies that included SRQs and electronic monitoring devices to measure adherence and focused on the SRQs that were found to be moderately to highly correlated with the monitoring devices. Of the 1679 citations found via the primary search, 41 full-text articles were reviewed for correlation between monitoring devices and SRQs. A majority (68%) of articles reported high (27%), moderate (29%) or significant (12%) correlation between monitoring devices (37 using Medication Event Monitoring System [MEMS®] and four using other devices) and SRQs (11 identified and numerous other unnamed SRQs). The most commonly used SRQs were the Adult/Pediatric AIDS Clinical Trial Group (AACTG/PACTG; 24.4%, 10/41) followed by the 4-item Morisky (9.8%, 4/41), Brief Medication Questionnaire (9.8%, 4/41) and visual analogue scale (VAS; 7.3%, 3/41). Although study designs differed across the articles, SRQs appeared to report a higher rate of medication adherence (+14.9%) than monitoring devices. In conclusion, several medication adherence SRQs were validated using electronic monitoring devices. A majority of them showed high or moderate correlation with medication adherence measured using monitoring devices, and could be considered for measuring patient

  13. Interventions to Increase Treatment Adherence in Pediatric Atopic Dermatitis: A Systematic Review

    Alexandria M. Bass

    2015-01-01

    Full Text Available Poor adherence to treatment is a major factor limiting treatment outcomes in patients with atopic dermatitis. The purpose of our systematic review is to identify techniques that have been tested to increase treatment adherence in atopic dermatitis. A MEDLINE search was performed for clinical trials focusing on interventions used to increase adherence in atopic dermatitis. Four articles were retrieved. References of these studies were analyzed yielding three more trials. The seven results were evaluated by comparing the intervention used to improve adherence, how adherence was assessed, and the outcome of the intervention tested. Different approaches to increase adherence such as written eczema action plans, educational workshops, extra office visits, and use of an atopic dermatitis educator were evaluated. All interventions increased adherence rates or decreased severity in patients, except for two. The MEDLINE search yielded limited results due to a lack of studies conducted specifically for atopic dermatitis and adherence was measured using different methods making the studies difficult to compare. Interventions including patient education, eczema action plans, and a quick return for a follow-up visit improve adherence, but based on the lack of clinical trials, developing new techniques to improve adherence could be as valuable as developing new treatments.

    Effective psychopharmacological medication with good tolerability represents the cornerstone of treatment for severe mental illness; however, the 1-year adherence rates are only approximately 50%. The term adherence emphasizes the collaborative responsibility of the clinician and the patient for a positive treatment outcome. Reasons for non-adherence are manifold and include patient-specific factors, such as self-stigmatization, lack of social and familial support, cognitive impairment and substance use besides insufficient effectiveness and the occurrence of side effects of the psychotropic drugs. To enhance adherence, both clinician and patient have to fully understand all the reasons for and against adherence to medication before a collaborative decision is made on future long-term treatment. A positive attitude towards medication critically depends on whether patients feel that the medication supports the attainment of the individual goals.

    Background Clinical trials are the gold standard of evidence-based practice. Still many papers inadequately report methodology in randomized controlled trials (RCTs), particularly for mHealth interventions for people with serious mental health problems. To ensure robust enough evidence, it is important to understand which study phases are the most vulnerable in the field of mental health care. Objective We mapped the recruitment and the trial follow-up periods of participants to provide a picture of the dropout predictors from a mHealth-based trial. As an example, we used a mHealth-based multicenter RCT, titled “Mobile.Net,” targeted at people with serious mental health problems. Methods Recruitment and follow-up processes of the Mobile.Net trial were monitored and analyzed. Recruitment outcomes were recorded as screened, eligible, consent not asked, refused, and enrolled. Patient engagement was recorded as follow-up outcomes: (1) attrition during short message service (SMS) text message intervention and (2) attrition during the 12-month follow-up period. Multiple regression analysis was used to identify which demographic factors were related to recruitment and retention. Results We recruited 1139 patients during a 15-month period. Of 11,530 people screened, 36.31% (n=4186) were eligible. This eligible group tended to be significantly younger (mean 39.2, SD 13.2 years, P<.001) and more often women (2103/4181, 50.30%) than those who were not eligible (age: mean 43.7, SD 14.6 years; women: 3633/6514, 55.78%). At the point when potential participants were asked to give consent, a further 2278 refused. Those who refused were a little older (mean 40.2, SD 13.9 years) than those who agreed to participate (mean 38.3, SD 12.5 years; t1842=3.2, P<.001). We measured the outcomes after 12 months of the SMS text message intervention. Attrition from the SMS text message intervention was 4.8% (27/563). The patient dropout rate after 12 months was 0.36% (4/1123), as

    Behavioral interventions for insomnia are effective in improving sleep, yet adherence is variable, and predictors of adherence have not been consistently replicated. The relationships between daily variations in state factors at the initiation of treatment and adherence have not been investigated. Using 2-week, self-report online logs, this study determined, among 53 college students with probable insomnia, the associations of pretreatment factors and daily factors during treatment on daily variations in adherence to one session of behavioral treatments for insomnia. These treatments included stimulus control therapy (SCT), sleep restriction therapy (SRT), and sleep hygiene (SH). Low self-efficacy was associated with poorer SCT and SH adherence. Participants with a "bed partner or pet" at least some of the time had better SCT adherence. Greater total sleep time and poorer sleep quality were associated with poor SCT and SRT adherence the following night. Greater sleep efficiency was related to greater next night SCT and SRT adherence. Alcohol consumption was related to poorer SRT and SH adherence the following night. Future studies should test the replicability of these findings. Adherence trials may want to test whether discouraging alcohol intake, enhancing treatment-related self-efficacy, and monitoring and providing feedback on sleep, early in treatment, affects adherence.

  1. Assessing Medication Adherence as a Standard of Care in Pediatric Oncology.

    Pai, Ahna L H; McGrady, Meghan E

    2015-12-01

    Poor adherence to pediatric cancer treatment protocols may prevent children and adolescents from realizing the potential benefits of therapy. This paper presents the evidence for a standard of care for supporting medication adherence. Databases were reviewed for articles examining adherence and including children and/or adolescents with cancer. Fourteen articles (i.e., qualitative, quantitative, review, and randomized clinical trials) were evaluated for rigor. There is moderate-quality evidence to support a strong recommendation for adherence to be assessed routinely and monitored throughout the treatment. Integrating the proposed clinical procedures into standard clinical care may improve outcomes for children and adolescents with cancer.

    Introduction It is unclear whether using peers can improve adherence to antiretroviral therapy (ART). To construct the World Health Organization's global guidance on adherence interventions, we conducted a systematic review and network meta-analysis to determine the effectiveness of using peers for achieving adequate adherence and viral suppression. Methods We searched for randomized clinical trials of peer-based interventions to promote adherence to ART in HIV populations. We searched six electronic databases from inception to July 2015 and major conference abstracts within the last three years. We examined the outcomes of adherence and viral suppression among trials done worldwide and those specific to low- and middle-income countries (LMIC) using pairwise and network meta-analyses. Results and discussion Twenty-two trials met the inclusion criteria. We found similar results between pairwise and network meta-analyses, and between the global and LMIC settings. Peer supporter+Telephone was superior in improving adherence than standard-of-care in both the global network (odds-ratio [OR]=4.79, 95% credible intervals [CrI]: 1.02, 23.57) and the LMIC settings (OR=4.83, 95% CrI: 1.88, 13.55). Peer support alone, however, did not lead to improvement in ART adherence in both settings. For viral suppression, we found no difference of effects among interventions due to limited trials. Conclusions Our analysis showed that peer support leads to modest improvement in adherence. These modest effects may be due to the fact that in many settings, particularly in LMICs, programmes already include peer supporters, adherence clubs and family disclosures for treatment support. Rather than introducing new interventions, a focus on improving the quality in the delivery of existing services may be a more practical and effective way to improve adherence to ART. PMID:27914185

    Full Text Available Abstract Background Successful antiretroviral treatment is dependent on sustaining high rates of adherence. In the southern African context, only a handful of studies (both quantitative and qualitative have looked at the determinants including a health behaviour theory of adherence to antiretroviral therapy. The aim of this study is to assess factors including the information, motivation and behavioural skills model (IMB contributing to antiretroviral (ARV adherence six months after commencing ARVs at three public hospitals in KwaZulu-Natal, South Africa. Methods Using systematic sampling, 735 HIV-positive patients were selected prior to commencing on ART from outpatient departments from three hospitals and followed-up at six months and interviewed with a questionnaire. Results A good proportion of patients were found to be adherent using both adherence instruments (visual analog scale = VAS 82.9%; Adult AIDS Clinical Trials Group = AATCG 70.8%. After adjusting for significant socio-economic variables, both the VAS and the dose, schedule and food adherence indicator found levels of adherence amongst urban residents to be almost 3 times greater than that of rural residents. After adjusting for health-related variables, for both indicators better adherence was associated with low depression and poorer adherence was associated with poor environmental factors. Adjusted odds ratios for adherence when taking into account different behavioural variables were for both adherence indicators, discrimination experiences were associated with lower adherence, and higher scores in adherence information and behavioural skills were associated with higher adherence. For the VAS adherence indicator, higher social support scores were associated with higher adherence. For the dose, schedule and food adherence indicator, using herbal medicines for HIV was associated with lower adherence. Conclusion For the patients in this study, particularly those not living in

  4. Attributes Associated with Adherence to Glaucoma Medical Therapy and its Effects on Glaucoma Outcomes: An Evidence-Based Review and Potential Strategies to Improve Adherence.

    Joseph, Arun; Pasquale, Louis R

    2017-01-01

    The treatment paradigm in glaucoma classically starts with exhausting all medical therapy prior to proceeding with laser or incisional surgery, although laser-first and surgery-first strategies have been explored in randomized clinical trials. Although glaucoma drops are proven to work well to lower intraocular pressure, slow the conversion from ocular hypertension, and slow the progression of disease in early open angle glaucoma, adherence to treatment is likely optimum in the randomized clinical trials that support these claims. In real-world scenarios, medical therapy often fails and practitioners are forced to proceed with more invasive treatment modalities to slow the progression of this blinding disease. This review aims to take an evidence-based approach to study the risk factors for poor adherence in glaucoma patients, to determine whether poor adherence is, in fact, associated with worse outcomes, and to seek potential strategies to improve adherence in these patients.

The sample comprised 304 male and female ART recipients at two President's Emergency Plan For AIDS Relief-supported HIV clinics. Using an interview schedule, we assessed patients' alcohol use (Alcohol Use Disorders Identification Test, other drug use, level of adherence to ART, and reasons for missing ART doses (AIDS Clinical Trials Group adherence instrument. Additionally, patients’ views were solicited on: the likely effectiveness of potential facilitators; the preferred quantity, duration, format, and setting of the sessions; the usefulness of having family members/friends attend sessions along with the patient; and potential skill sets to be imparted.Results: About half of the male drinkers’ and three quarters of the female drinkers’ Alcohol Use Disorders Identification Test scores were suggestive of hazardous or harmful drinking. Average self-reported ART adherence was 89.7%. There was a significant association between level of alcohol use and degree of ART adherence. Overall, participants perceived two clinic-based sessions, each of one hour’s duration, in a group format, and facilitated by a peer or adherence counselor, as most appropriate and acceptable. Participants also had a favorable attitude towards family and friends accompanying them to the sessions. They also favored an

  7. Modeling the impact of increased adherence to asthma therapy.

    Amory Schlender

    Full Text Available BACKGROUND: Nonadherence to medications occurs in up to 70% of patients with asthma. The effect of improving adherence is not well quantified. We developed a mathematical model with which to assess the population-level effects of improving medication prescribing and adherence for asthma. METHODS: A mathematical model, calibrated to clinical trial data from the U.S. NHLBI-funded SOCS trial and validated using data from the NHLBI SLIC trial, was used to model the effects of increased prescribing and adherence to asthma controllers. The simulated population consisted of 4,930 individuals with asthma, derived from a sample the National Asthma Survey. Main outcomes were controller use, reliever use, unscheduled doctor visits, emergency department (ED visits, and hospitalizations. RESULTS: For the calibration, simulated outcomes agreed closely with SOCS trial outcomes, with treatment failure hazard ratios [95% confidence interval] of 0.92 [0.58-1.26], 0.97 [0.49-1.45], and 1.01 [0-1.87] for simulation vs. trial in the in placebo, salmeterol, and triamcinolone arms, respectively. For validation, simulated outcomes predicted mid- and end-point treatment failure rates, hazard ratios 1.21 [0.08-2.34] and 0.83 [0.60-1.07], respectively, for patients treated with salmeterol/triamcinolone during the first half of the SLIC study and salmeterol monotherapy during the second half. The model performed less well for patients treated with salmeterol/triamcinolone during the entire study duration, with mid- and end-point hazard ratios 0.83 [0.00-2.12] and 0.37 [0.10-0.65], respectively. Simulation of optimal adherence and prescribing indicated that closing adherence and prescription gaps could prevent as many as nine million unscheduled doctor visits, four million emergency department visits, and one million asthma-related hospitalizations each year in the U.S. CONCLUSIONS: Improvements in medication adherence and prescribing could have a substantial impact on

    Full Text Available Abstract Background The aims of this study were to describe outcome with respect to persistent psychotic symptoms, relapse of positive symptoms, hospital admissions, and application of treatment by coercion among patients with recent onset schizophrenia being adherent and non-adherent to anti-psychotic medication. Materials and methods The study included 50 patients with recent onset schizophrenia, schizoaffective or schizophreniform disorders. The patients were clinically stable at study entry and had less than 2 years duration of psychotic symptoms. Good adherence to antipsychotic medication was defined as less than one month without medication. Outcomes for poor and good adherence were compared over a 24-month follow-up period. Results The Odds Ratio (OR of having a psychotic relapse was 10.27 and the OR of being admitted to hospital was 4.00 among non-adherent patients. Use of depot-antipsychotics were associated with relapses (OR = 6.44. Conclusion Non-adherence was associated with relapse, hospital admission and having persistent psychotic symptoms. Interventions to increase adherence are needed. Trial registration Current Controlled Trials NCT00184509. Key words: Adherence, schizophrenia, antipsychotic medication, admittances, relapse.

    Full Text Available Introduction: Phenylketonuria (PKU is caused by the deficient activity of phenylalanine hydroxylase. Aim: To identify the factors associated with treatment adherence among patients with PKU seen at a southern Brazil reference center. Methodology: A cross-sectional, outpatient-based study including 56 patients with PKU (median age, 12 years for whom a Phe-restrict diet plus specific metabolic formula have been prescribed. Patients were considered adherent or nonadherent depending on the median phenylalanine concentration for the 12 months prior to study and target levels of phenylalanine for each age range (<13 years = ≤360 µmol/L; ≥13 years = ≤900 µmol/L. Data were collected through a review of patient’s medical records and a set of interviews with patients and their relatives. Results: Eighteen patients (32.1%; ≥13 years, 11 were classified as treatment adherent. Among all factors analyzed, only mental retardation, living with parents, and level of maternal education were associated with adherence to treatment. Conclusion: Our findings reinforce the importance of the family as promoting factor for treatment adherence.

    Full Text Available BACKGROUND: There is a high demand for stroke rehabilitation in the Brazilian public health system which should make undertaking clinical trials straightforward. OBJECTIVES: The aims of this study were to 1 determine the rate of recruitment of community-dwelling stroke survivors into a randomized trial of the effects of strength training in addition to task-specific gait training, 2 compare the effectiveness of various recruitment strategies on accrual rates, and 3 determine the attendance at training sessions and adherence to the intervention protocol. METHODS: Participants within six months of a stroke were screened for eligibility and invited to participate. Recruitment strategies were classified as advertisement or referral. The number of people who were screened, eligible and recruited for each strategy was recorded. Attendance at training sessions and adherence to the intervention protocol were recorded. RESULTS: Over the first 14 months, 150 stroke survivors were screened, 10 were recruited, and 35 (23% were eligible. Twenty-five of these patients (71% were unable to participate with lack of transport given as the most common reason. The most successful strategy was referral via hospital-based physical therapists (50%. Overall attendance was 72% with lack of transport being the most common reason for non-attendance. Overall adherence to the protocol was 97% with feeling unwell being the most common reason for non-adherence. CONCLUSIONS: Recruitment of stroke survivors was inefficient. Lack of transport was the most common barrier to participate in and attend training sessions. Funding for transport is essential to make carrying out trials in Brazil feasible.

  12. The influence of cognition, anxiety and psychiatric disorders over treatment adherence in uncontrolled hypertensive patients.

    Úrsula Jacobs

    Full Text Available BACKGROUND: Poor adherence is estimated to cause 125 thousand deaths per year and is linked to 10% of all hospital stays in the U.S. Up to one third of elderly hypertensive patients don't have adherence, which is responsible for high proportion of hospitalizations. Hypertension is also related to poor performance in tests that assess cognitive functions. On the other hand, poor cognitive performance is associated with low adherence to treatment. OBJECTIVE: To assess the association between cognitive function, anxiety and psychiatric disorders with adherence to drug treatment in patients with hypertension. METHODOLOGY AND PRINCIPAL FINDINGS: This a cohort studies with 56 adult patients with uncontrolled hypertension who participated of all meetings of a pharmaceutical intervention in a randomized clinical trial of pharmaceutical care. Cognitive function was measured by the Mini Mental State Examination (Mini-mental. The memory was measured by digit and word spans, tower and church shadow test, short story test and metamemory. Anxiety and psychiatric disorders were evaluated by the State Trace Anxiety Inventory and the Self-Report Questionnaire, respectively. The participants were classified as adherent or non-adherent to the drug treatment, according to the identification of plasma levels of hydrochlorothiazide. All non-adherent patients (n = 12 and 35 out 44 (79.5% patients with adherence to treatment had at least one memory test with an altered score (P = 0.180. Participants with an unsatisfactory score in the Mini-mental had six-fold higher risk of non-adherence to treatment when compared to those with a normal score (RR = 5.8; CI 95%: 1.6-20.8; P = 0.007. The scores of anxiety and psychiatric disorders were not associated with adherence to the pharmacological treatment. CONCLUSION: Cognitive deficit impairs adherence to drug therapy and should be screened as part of a program of pharmaceutical care to improve adherence to

    2013-01-01

    Although evidence-based pharmacotherapies are a principal component of patient care, 30-50% of patients do not take their medications as prescribed. We conducted a randomized trial of two clinical decision support (CDS) interventions in 2219 patients: patient adherence reports to providers (n=744), patient adherence reports to providers + email notices to care managers (n=736), and controls (739). At 18-month follow-up, there were no treatment-related differences in patient medication adherence (overall, by medication class, and by medical condition). There also were no treatment-related differences in patient clinical and economic outcomes. Thus, while this study's CDS information interventions were successfully delivered to providers and care managers, and were effective in identifying medication adherence deficits and in increasing care manager responses to medication adherences issues, these interventions were not able to alter patient medication behavior.

  14. Adherence with Preventive Medication in Childhood Asthma

    Scott Burgess

    2011-01-01

    Full Text Available Suboptimal adherence with preventive medication is common and often unrecognised as a cause of poor asthma control. A number of risk factors for nonadherence have emerged from well-conducted studies. Unfortunately, patient report a physician's estimation of adherence and knowledge of these risk factors may not assist in determining whether non-adherence is a significant factor. Electronic monitoring devices are likely to be more frequently used to remind patients to take medication, as a strategy to motivate patients to maintain adherence, and a tool to evaluate adherence in subjects with poor disease control. The aim of this paper is to review non-adherence with preventive medication in childhood asthma, its impact on asthma control, methods of evaluating non-adherence, risk factors for suboptimal adherence, and strategies to enhance adherence.

    Oral biofilms such as dental plaque cause dental caries and periodontitis, as well as aspiration pneumonia and infectious endocarditis by translocation. Hence, the suppression of oral biofilm formation is an issue of considerable importance. Mechanical removal, disinfectants, inhibition of polysaccharide formation, and artificial sugar have been used for the reduction of oral biofilm. From the viewpoint of the inhibition of bacterial adherence, we investigated whether aqueous biocompatible 2-methacryloyloxyethyl phosphorylcholine (MPC)-polymer can reduce streptococcal colonization and biofilm formation. We examined the effects of MPC-polymer on streptococcal adherence to saliva-coated hydroxyapatite and oral epithelial cells, and the adherence of Fusobacterium nucleatum to streptococcal biofilm. MPC-polymer application markedly inhibited both the adherence and biofilm formation of Streptococcus mutans on saliva-coated hydroxyapatite and streptococcal adherence to oral epithelial cells, and reduced the adherence of F. nucleatum to streptococcal biofilms. A small-scale clinical trial revealed that mouthrinsing with MPC-polymer inhibited the increase of oral bacterial numbers, especially of S. mutans. These findings suggest that MPC-polymer is a potent inhibitor of bacterial adherence and biofilm development, and may be useful to prevent dental-plaque-related diseases.

  16. Preliminary Evidence for Feasibility, Use, and Acceptability of Individualized Texting for Adherence Building for Antiretroviral Adherence and Substance Use Assessment among HIV-Infected Methamphetamine Users

    David J. Moore

    2013-01-01

    Full Text Available The feasibility, use, and acceptability of text messages to track methamphetamine use and promote antiretroviral treatment (ART adherence among HIV-infected methamphetamine users was examined. From an ongoing randomized controlled trial, 30-day text response rates of participants assigned to the intervention (individualized texting for adherence building (iTAB, n = 20 were compared to those in the active comparison condition (n = 9. Both groups received daily texts assessing methamphetamine use, and the iTAB group additionally received personalized daily ART adherence reminder texts. Response rate for methamphetamine use texts was 72.9% with methamphetamine use endorsed 14.7% of the time. Text-derived methamphetamine use data was correlated with data from a structured substance use interview covering the same time period (P<0.05. The iTAB group responded to 69.0% of adherence reminder texts; among those responses, 81.8% endorsed taking ART medication. Standardized feedback questionnaire responses indicated little difficulty with the texts, satisfaction with the study, and beliefs that future text-based interventions would be helpful. Moreover, most participants believed the intervention reduced methamphetamine use and improved adherence. Qualitative feedback regarding the intervention was positive. Future studies will refine and improve iTAB for optimal acceptability and efficacy. This trial is registered with ClinicalTrials.gov NCT01317277.

  17. Biomarkers and biometric measures of adherence to use of ARV-based vaginal rings

    Randy M Stalter

    2016-05-01

    Full Text Available Introduction: Poor adherence to product use has been observed in recent trials of antiretroviral (ARV-based oral and vaginal gel HIV prevention products, resulting in an inability to determine product efficacy. The delivery of microbicides through vaginal rings is widely perceived as a way to achieve better adherence but vaginal rings do not eliminate the adherence challenges exhibited in clinical trials. Improved objective measures of adherence are needed as new ARV-based vaginal ring products enter the clinical trial stage. Methods: To identify technologies that have potential future application for vaginal ring adherence measurement, a comprehensive literature search was conducted that covered a number of biomedical and public health databases, including PubMed, Embase, POPLINE and the Web of Science. Published patents and patent applications were also searched. Technical experts were also consulted to gather more information and help evaluate identified technologies. Approaches were evaluated as to feasibility of development and clinical trial implementation, cost and technical strength. Results: Numerous approaches were identified through our landscape analysis and classified as either point measures or cumulative measures of vaginal ring adherence. Point measurements are those that give a measure of adherence at a particular point in time. Cumulative measures attempt to measure ring adherence over a period of time. Discussion: Approaches that require modifications to an existing ring product are at a significant disadvantage, as this will likely introduce additional regulatory barriers to the development process and increase manufacturing costs. From the point of view of clinical trial implementation, desirable attributes would be high acceptance by trial participants, and little or no additional time or training requirements on the part of participants or clinic staff. We have identified four promising approaches as being high priority

    2010-01-01

    Full Text Available Abstract Background Induction-maintenance therapy is a treatment regime where patients are prescribed an intense course of treatment for a short period of time (the induction phase, followed by a simplified long-term regimen (maintenance. Since induction therapy has a significantly higher chance of pill fatigue than maintenance therapy, patients might take drug holidays during this period. Without guidance, patients who choose to stop therapy will each be making individual decisions, with no scientific basis. Methods We use mathematical modelling to investigate the effect of imperfect adherence during the inductive phase. We address the following research questions: 1. Can we theoretically determine the maximal length of a possible drug holiday and the minimal number of doses that must subsequently be taken while still avoiding resistance? 2. How many drug holidays can be taken during the induction phase? Results For a 180 day therapeutic program, a patient can take several drug holidays, but then has to follow each drug holiday with a strict, but fairly straightforward, drug-taking regimen. Since the results are dependent upon the drug regimen, we calculated the length and number of drug holidays for all fifteen protease-sparing triple-drug cocktails that have been approved by the US Food and Drug Administration. Conclusions Induction therapy with partial adherence is tolerable, but the outcome depends on the drug cocktail. Our theoretical predictions are in line with recent results from pilot studies of short-cycle treatment interruption strategies and may be useful in guiding the design of future clinical trials.

  19. Sticker charts: a method for improving adherence to treatment of chronic diseases in children.

    Poor adherence is a common problem and may be an underlying cause of poor clinical outcomes. In pediatric populations, positive reinforcement techniques such as sticker charts may increase motivation to adhere to treatment regimens. To review the use of sticker charts to improve adherence in children with chronic disease, Medline and PsycINFO searches were conducted using the key words "positive reinforcement OR behavior therapy" and "adherence OR patient compliance" and "child." Randomized controlled retrospective cohort or single-subject-design studies were selected. Studies reporting adherence to the medical treatment of chronic disease in children using positive reinforcement techniques were included in the analysis. The systematic search was supplemented by identifying additional studies identified through the reference lists and authors of the initial articles found. Positive reinforcement techniques such as sticker charts increase adherence to medical treatment regimens. In several studies, this effect was maintained for months after the initial intervention. Better adherence correlated with better clinical outcomes in some, but not all, studies. Few studies examining the use of sticker charts were identified. Although single-subject-design studies are useful in establishing the effect of a behavioral intervention, larger randomized controlled trials would help determine the precise efficacy of sticker chart interventions. Adherence to medical treatments in children can be increased using sticker charts or other positive reinforcement techniques. This may be an effective means to encourage children with atopic dermatitis to apply their medications and improve clinical outcomes.

    Objectives Adherence is critical for maximizing the effectiveness of preexposure prophylaxis (PrEP) in preventing HIV infection. Strategies for promoting adherence to HIV treatment, and their potential application to PrEP adherence, have received considerable attention. However, adherence promotion strategies for prevention medications have not been well characterized and may be more applicable to PrEP. We aimed to identify adherence support interventions that have been effective in other prevention fields and could be applied in the HIV prevention context to support pill taking among PrEP users. Methods To identify adherence support interventions that could be evaluated and applied in the PrEP context, we conducted a systematic review across the following prevention fields: hypertension, latent tuberculosis infection, hyperlipidemia, oral contraceptives, osteoporosis, malaria prophylaxis, and post-exposure prophylaxis for HIV infection. We included randomized controlled trials that evaluated the efficacy of interventions to improve adherence to daily oral medications prescribed for primary prevention in healthy individuals or for secondary prevention in asymptomatic individuals. Results Our searches identified 585 studies, of which 48 studies met the eligibility criteria and were included in the review; nine evaluated multiple strategies, yielding 64 separately tested interventions. Interventions with the strongest evidence for improving adherence included complex, resource-intensive interventions, which combined multiple adherence support approaches, and low-cost, low-intensity interventions that provided education or telephone calls for adherence support. Conclusions Our review identified adherence interventions with strong evidence of efficacy across prevention fields and provides recommendations for evaluating these interventions in upcoming PrEP studies.

    Conclusion: Although medical treatments and drug industry develop day by day, there have been no changes in the treatment adherence ratios in the past years. To generate possible solutions, treatment adherence should be assessed in all clinical interviews and if patient is non-adherent this issue should be handled seriously.

This review considers the most recent developments in adherence research with a focus on the impact of medication adherence on health care costs in the US health system. We describe the magnitude of the nonadherence problem and related costs, with an extensive discussion of the mechanisms underlying the impact of nonadherence on costs. Specifically, we summarize the impact of nonadherence on health care costs in several chronic diseases, such as diabetes and asthma. A brief analysis of existing research study designs, along with suggestions for future research focus, is provided. Finally, given the ongoing changes in the US health care system, we also address some of the most relevant and current trends in health care, including pharmacist-led medication therapy management and electronic (e-prescribing.

    Neuronal networks have been widely used for neurophysiology, drug discovery and toxicity testing. An essential prerequisite for future widespread application of neuronal networks is the development of efficient cryopreservation protocols to facilitate their storage and transportation. Here is the first report on cryopreservation of mammalian adherent neuronal networks. Dissociated spinal cord cells were attached to a poly-d-lysine/laminin surface and allowed to form neuronal networks. Adherent neuronal networks were embedded in a thin film of collagen gel and loaded with trehalose prior to transfer to a freezing medium containing DMSO, FBS and culture medium. This was followed by a slow rate of cooling to -80 degrees C for 24 h and then storage for up to 2 months in liquid nitrogen at -196 degrees C. The three components: DMSO, collagen gel entrapment and trehalose loading combined provided the highest post-thaw viability, relative to individual or two component protocols. The post-thaw cells with this protocol demonstrated similar neuronal and astrocytic markers and morphological structure as those detected in unfrozen cells. Fluorescent dye FM1-43 staining revealed active recycling of synaptic vesicles upon depolarizing stimulation in the post-thaw neuronal networks. These results suggest that a combination of DMSO, collagen gel entrapment and trehalose loading can significantly improve conventional slow-cooling methods in cryopreservation of adherent neuronal networks.

    Optimal adherence to antiretroviral therapy (ART) is key to viral suppression, but may be impeded by psychosocial consequences of HIV-infection such as stigma and depression. Measures of adherence in India have been examined in clinic populations, but little is known about the performance of these measures outside clinical settings. We conducted a cross-sectional study of 151 Tamil-speaking people living with HIV/AIDS (PLHA) in India recruited through HIV support networks and compared single item measures from the Adult AIDS Clinical Trial Group (AACTG) scale, a visual analog scale (VAS), and a question on timing of last missed dose. Depression was measured using the Major Depression Inventory (MDI) and HIV-related stigma was measured using an adaptation of the Berger Stigma Scale. Mean age was 35.6 years (SD±5.9); 55.6% were male; mean MDI score was 11.9 (SD±9.1); and mean stigma score was 67.3 (SD±12.0). Self-reported perfect adherence (no missed doses) was 93.3% using the AACTG item, 87.1% using last missed dose, and 83.8% using the VAS. The measures had moderate agreement with each other (kappa 0.45 - 0.57). Depression was associated with lower adherence irrespective of adherence measure used, and remained significantly associated in multivariable analyses adjusting for age and marital status. Stigma was not associated with adherence irrespective of the measure used. The VAS captured the greatest number of potentially non-adherent individuals and may be useful for identifying PLHA in need of adherence support. Given the consistent and strong association between poorer adherence and depression, programs that jointly address adherence and mental health for PLHA in India may be more effective than programs targeting only one.

    Full Text Available Introduction: There is little information on adherence to antiretroviral therapy (ART in the Eastern European region. This prospective study evaluated multiple measures of adherence and their association with viral suppression among HIV patients in Georgia. Methods: A prospective cohort study enrolled 100 consecutive antiretroviral-naïve adult (age ≥18 years patients, who were followed for three months. Adherence was assessed by medication refill and three self-report measures (an AIDS Clinical Trial Group [ACTG] tool for four-day adherence, a visual analogue scale [VAS] and a rating task for 30-day adherence. The VAS represented a line anchored by 0 and 100% corresponding to the percentage of prescribed doses taken. The rating task asked patients to rate their ability to take all medications as prescribed, with responses categorized into six levels of adherence: very poor (0%, poor (20%, fair (40%, good (60%, very good (80% and excellent (100%. Patients with adherence of ≥95% by medication refill, ACTG and VAS, and ≥80% by rating task, were defined as adherent. Results: Of 100 patients enrolled, eight had missing data and were excluded from analysis. Among the remaining 92 patients, the median age was 39 years, and 70% were men. Major modes of HIV acquisition were injection drug use (IDU; 47.3% and heterosexual contact (44.1%. The proportions of adherent patients were as follows: 68% by medication refill, 90% by ACTG questionnaire, 38% by VAS and 42% by rating task. On average, four months after commencing ART, 52 (56.5% patients had a viral load <400 copies/ml and 26 (28.3% patients had a viral load <50 copies/ml. Of 43 persons with a history of IDU, 22 (51.2% reached a viral load of <400 copies/ml. In multivariate analysis, only refill adherence was a statistically significant predictor of viral suppression of <400 copies/ml: the risk ratio was 1.7 (95% CI: 1.1–2.8.

  9. Experiences of non-adherence to Internet-delivered cognitive behavior therapy: A qualitative study

    Olof Johansson

    2015-05-01

    Full Text Available Many trials on Internet-delivered psychological treatments have had problems with nonadherence, but not much is known about the subjective reasons for non-adhering. The aim of this study was to explore participants' experiences of non-adherence to Internet-delivered psychological treatment. Grounded theory was used to analyze data from seven in-depth interviews with persons who had non-adhered to a study on Internet-delivered cognitive behavioral therapy for generalized anxiety disorder. The process of non-adherence is described as an interaction between patient factors and treatment factors. A working model theory was generated to illustrate the experience of nonadherence. The model describes a process where treatment features such as workload, text-content complexity and treatment process don't match personal prerequisites regarding daily routines, perceived language skills and treatment expectations respectively, resulting in the decision to nonadhere. Negative effects were also stated as a reason for non-adherence. Several common strategies used for increasing adherence to Internet-delivered therapy in general are by these non-completers regarded as factors directly related to their reason for non-adherence.

  10. Psychosocial Syndemics are Additively Associated with Worse ART Adherence in HIV-Infected Individuals.

    Blashill, Aaron J; Bedoya, C Andres; Mayer, Kenneth H; O'Cleirigh, Conall; Pinkston, Megan M; Remmert, Jocelyn E; Mimiaga, Matthew J; Safren, Steven A

    2015-06-01

    Adherence to antiretroviral therapy (ART) among HIV-infected individuals is necessary to both individual and public health, and psychosocial problems have independently been associated with poor adherence. To date, studies have not systematically examined the effect of multiple, co-occurring psychosocial problems (i.e., "syndemics") on ART adherence. Participants included 333 HIV-infected individuals who completed a comprehensive baseline evaluation, as part of a clinical trial to evaluate an intervention to treat depression and optimize medication adherence. Participants completed self-report questionnaires, and trained clinicians completed semi-structured diagnostic interviews. ART non-adherence was objectively measured via an electronic pill cap (i.e., MEMS). As individuals reported a greater number of syndemic indicators, their odds of non-adherence increased. Co-occurring psychosocial problems have an additive effect on the risk for poor ART adherence. Future behavioral medicine interventions are needed that address these problems comprehensively, and/or the core mechanisms that they share.

  11. A systematic review of antiretroviral adherence interventions for HIV-infected people who use drugs.

    Binford, Meredith Camp; Kahana, Shoshana Y; Altice, Frederick L

    2012-12-01

    HIV-infected persons who use drugs (PWUDs) are particularly vulnerable for suboptimal combination antiretroviral therapy (cART) adherence. A systematic review of interventions to improve cART adherence and virologic outcomes among HIV-infected PWUDs was conducted. Among the 45 eligible studies, randomized controlled trials suggested directly administered antiretroviral therapy, medication-assisted therapy (MAT), contingency management, and multi-component, nurse-delivered interventions provided significant improved short-term adherence and virologic outcomes, but these effects were not sustained after intervention cessation. Cohort and prospective studies suggested short-term increased cART adherence with MAT. More conclusive data regarding the efficacy on cART adherence and HIV treatment outcomes using cognitive behavioral therapy, motivational interviewing, peer-driven interventions and the integration of MAT into HIV clinical care are warranted. Of great concern was the virtual lack of interventions with sustained post-intervention adherence and virologic benefits. Future research directions, including the development of interventions that promote long-term improvements in adherence and virologic outcomes, are discussed.

  12. Matching adherence interventions to patient determinants using the Theoretical Domains Framework

    Samuel Sebastian Allemann

    2016-11-01

    Full Text Available IntroductionDespite much research, interventions to improve medication adherence report disappointing and inconsistent results. Tailored approaches that match interventions and patient determinants of non-adherence were seldom used in clinical trials. The presence of a multitude of theoretical frameworks and models to categorize interventions and patient determinants complicated the development of common categories shared by interventions and determinants. We retrieved potential interventions and patient determinants from published literature on medication adherence, matched them like locks and keys, and categorized them according to the Theoretical Domains Framework (TDF.MethodsWe identified the most relevant literature reviews on interventions and determinants in a pragmatic literature search, extracted all interventions and determinants, grouped similar concepts to umbrella terms and assigned them to TDF categories. All steps were finalized in consensus discussion between the authors.ResultsSixteen articles (5 with determinants, 11 with interventions were included for analysis. We extracted 103 interventions and 42 determinants that we divided in 26 modifiable and 16 unmodifiable determinants. All interventions and modifiable determinants were matched within 11 categories (Knowledge; Skills; Social/professional role and identity; Beliefs about capabilities; Beliefs about consequences; Intentions; Memory, Attention and decision processes; Environmental context and resources; Social influences; Emotion; and Behavioral regulation.ConclusionIn published trials on medication adherence, the congruence between interventions and determinants can be assessed with matching interventions to determinants. To be successful, interventions in medication adherence should target current modifiable determinants and be tailored to the unmodifiable determinants. Modifiable and unmodifiable determinants need to be assessed at inclusion of intervention studies to

    Adherence is a major factor in the effectiveness of preexposure prophylaxis (PrEP) for HIV prevention. Modeling patterns of adherence helps to identify influential covariates of different types of adherence as well as to enable clinical trial simulation so that appropriate interventions can be developed. We developed a Markov mixed-effects model to understand the covariates influencing adherence patterns to daily oral PrEP. Electronic adherence records (date and time of medication bottle cap opening) from the Partners PrEP ancillary adherence study with a total of 1147 subjects were used. This study included once-daily dosing regimens of placebo, oral tenofovir disoproxil fumarate (TDF), and TDF in combination with emtricitabine (FTC), administered to HIV-uninfected members of serodiscordant couples. One-coin and first- to third-order Markov models were fit to the data using NONMEM(®) 7.2. Model selection criteria included objective function value (OFV), Akaike information criterion (AIC), visual predictive checks, and posterior predictive checks. Covariates were included based on forward addition (α = 0.05) and backward elimination (α = 0.001). Markov models better described the data than 1-coin models. A third-order Markov model gave the lowest OFV and AIC, but the simpler first-order model was used for covariate model building because no additional benefit on prediction of target measures was observed for higher-order models. Female sex and older age had a positive impact on adherence, whereas Sundays, sexual abstinence, and sex with a partner other than the study partner had a negative impact on adherence. Our findings suggest adherence interventions should consider the role of these factors.

  17. Moving from theory to research to practice. Implementing an effective dyadic intervention to improve antiretroviral adherence for clinic patients.

    Remien, Robert H; Stirratt, Michael J; Dognin, Joanna; Day, Emily; El-Bassel, Nabila; Warne, Patricia

    2006-12-01

    There is a dearth of evidence on the relative efficacy of intervention modalities to improve and maintain patient adherence to antiretroviral medications. Although empiric findings from research on HIV/AIDS, other diseases, and chronic medical conditions consistently demonstrate that social support plays an important role in facilitating adherence, few HIV/AIDS interventions have directly targeted this factor. Ewart's social action theory emphasizes the role of social relationships in behavior change and provides a comprehensive and useful guide to the development of interventions for adherence. We describe the development, content, and testing of SMART Couples, an effective antiretroviral adherence intervention that is grounded in social action theory and designed to enhance social support for ART adherence. Finally, we discuss some of the challenges of translating findings from the randomized clinical trial of this intervention into clinical practice and offer recommendations for integration of lessons learned into ongoing clinical care.

    Background Lack of adherence to pharmacological treatment is one of the main causes of low control rates in hypertension. Objective To verify treatment adherence and associated factors, as well as blood pressure (BP) control in participants of the Resistant Hypertension Optimal Treatment (ReHOT) clinical trial. Method Cross-sectional study including all 109 patients who had completed the ReHOT for at least 6 months. We excluded those participants who failed to respond to the new recruitment after three phone contact attempts. We evaluated the BP control by ambulatory BP monitoring (ABPM; controlled levels: 24-hour systolic and diastolic BP < 130 x 80 mmHg) and analyzed the patients' treatment adherence using the Morisky Medication Adherence Scale (MMAS) questionnaire validated by Bloch, Melo, and Nogueira (2008). The statistical analysis was performed with the software IBM SPSS statistics 21.0. We tested the normality of the data distribution with kurtosis and skewness. The variables tested in the study are presented with descriptive statistics. Comparisons between treatment adherence and other variables were performed with Student's t test for independent variables and Pearson's chi-square or Fisher's exact test. To conduct analyses among patients considering adherence to treatment and BP control, we created four groups: G0, G1, G2, and G3. We considered a 5% significance level in all tests. Results During the ReHOT, 80% of the patients had good BP control and treatment adherence. Of 96 patients reevaluated in the present study, only 52.1% had controlled hypertension when assessed by ABPM, while 31.3% were considered adherent by the MMAS. Regarding other ABPM measures, we observed an absence of a nocturnal dip in 64.6% of the patients and a white-coat effect and false BP control in 23% and 12.5%, respectively. Patients' education level showed a trend towards being a determinant factor associated with lack of adherence (p = 0.05). Resistant hypertension and number

    Adherence to StudentBodies™ proved to be high across a number of trials, settings and countries. These findings are promising, but it is likely that adherence will be distinctly lower in the general public than in research settings, and intervention effects will turn out smaller. However, the intervention is readily available at minimal cost per participant, and the public health impact may still be notable.

    Malaria infects 30,000 travelers annually worldwide. At greatest risk are those who travel for long duration. Prevention of malaria includes chemoprophylaxis. This prospective study on 121 travelers who visited two travel clinics shows that adherence to prophylactic treatment was low, especially in long duration trips, and that adherence rate could be predicted by the much more available intent-to-adhere rate.

    Full Text Available Patrick P Kneeland, Margaret C FangThe University of California, San Francisco Division of Hospital Medicine, San Francisco, CA, USAAbstract: Warfarin therapy reduces morbidity and mortality related to thromboembolism. Yet adherence to long-term warfarin therapy remains challenging due to the risks of anticoagulantassociated complications and the burden of monitoring. The aim of this paper is to review determinants of adherence and persistence on long-term anticoagulant therapy for atrial fibrillation and venous thromboembolism. We evaluate what the current literature reveals about the impact of warfarin on quality of life, examine warfarin trial data for patterns of adherence, and summarize known risk factors for warfarin discontinuation. Studies suggest only modest adverse effects of warfarin on quality of life, but highlight the variability of individual lifestyle experiences of patients on warfarin. Interestingly, clinical trials comparing anticoagulant adherence to alternatives (such as aspirin show that discontinuation rates on warfarin are not consistently higher than in control arms. Observational studies link a number of risk factors to warfarin non-adherence including younger age, male sex, lower stroke risk, poor cognitive function, poverty, and higher educational attainment. In addition to differentiating the relative impact of warfarin-associated complications (such as bleeding versus the lifestyle burdens of warfarin monitoring on adherence, future investigation should focus on optimizing patient education and enhancing models of physician–patient shared-decision making around anticoagulation.Keywords: anticoagulation, warfarin, adherence, persistence, thromboembolism

  3. Measurement of oxide adherence to PFM alloys.

    Mackert, J R; Parry, E E; Hashinger, D T; Fairhurst, C W

    1984-11-01

    A method has been reported for evaluating adherence of an oxide to its substrate metal to a maximum value of about 40 MPa. Oxidized alloy plates were cemented between two aluminum cylinders with a high-strength cyanoacrylate cement and loaded in tension until failure occurred either at the oxide/metal interface, within the oxide layer, or in the cement itself. Significant differences were found among the oxide adherence values obtained from different PFM alloys. The oxides formed on five of the alloys exhibited adherence strengths in excess of the published value for cohesive strength of dental opaque porcelain, indicating that they possess sufficient adherence to act as the transition zone between the porcelain and the alloy. In addition, a correspondence was found between the quality of porcelain bond for a given alloy and its oxide adherence strength. These results remove the principal objection to the oxide-layer theory of porcelain bonding in dental alloy systems and emphasize the importance of oxide adherence in the establishment of a bond. It is therefore suggested that future work devoted to porcelain-metal bonding should seek to elucidate the mechanism of oxide adherence to PFM alloys and explore the development of new alloys which form adherent oxides.

    Full Text Available Lindsay P Bodell, Pamela K KeelDepartment of Psychology, Florida State University, Tallahassee, FL, USAAbstract: Anorexia nervosa (AN is a serious psychiatric illness associated with significant medical and psychiatric morbidity, psychosocial impairment, increased risk of death, and chronicity. Given the severity of the disorder, the establishment of safe and effective treatments is necessary. Several treatments have been tried in AN, but few favorable results have emerged. This paper reviews randomized controlled trials in AN, and provides a synthesis of existing data regarding the efficacy, safety, and adherence associated with pharmacologic and psychological interventions. Randomized controlled trials for the treatment of AN published in peer-reviewed journals were identified by electronic and manual searches. Overall, pharmacotherapy has limited benefits in the treatment of AN, with some promising preliminary findings associated with olanzapine, an antipsychotic agent. No single psychological intervention has demonstrated clear superiority in treating adults with AN. In adolescents with AN, the evidence base is strongest for the use of family therapy over alternative individual psychotherapies. Results highlight challenges in both treating individuals with AN and in studying the effects of those treatments, and further emphasize the importance of continued efforts to develop novel interventions. Treatment trials currently underway and areas for future research are discussed.Keywords: anorexia nervosa, treatment, pharmacotherapy, psychotherapy, randomized controlled trials

    Clinical trial data have shown that oral pre-exposure prophylaxis (PrEP) is efficacious when taken as prescribed; however, PrEP adherence is complex and must be understood within the context of variable risk for HIV infection and use of other HIV prevention methods. Different levels of adherence may be needed in different populations to achieve HIV prevention, and the optimal methods for achieving the necessary adherence for both individual and public health benefits are unknown. Guidance for PrEP use must consider these questions to determine the success of PrEP-based HIV prevention programs. In this article, we propose a new paradigm for understanding and measuring PrEP adherence, termed prevention-effective adherence, which incorporates dynamic HIV acquisition risk behaviors and the use of HIV alternative prevention strategies. We discuss the need for daily PrEP use only during periods of risk for HIV exposure, describe key issues for measuring and understanding relevant behaviors, review lessons from another health prevention field (i.e., family planning), and provide guidance for prevention-effective PrEP use. Moreover, we challenge emerging calls for sustained, near perfect PrEP adherence regardless of risk exposure and offer a more practical and public health-focused vision for this prevention intervention.

    2015-03-01

    Full Text Available Background: The assessment of therapeutic adherence and competence is often neglected in psychotherapy research, particularly in children and adolescents; however, both variables are crucial for the interpretation of treatment effects. Objective: Our aim was to develop, adapt, and pilot two scales to assess therapeutic adherence and competence in a recent innovative program, Developmentally Adapted Cognitive Processing Therapy (D-CPT, for adolescents suffering from posttraumatic stress disorder (PTSD after childhood abuse. Method: Two independent raters assessed 30 randomly selected sessions involving 12 D-CPT patients (age 13–20 years, M age=16.75, 91.67% female treated by 11 therapists within the pilot phase of a multicenter study. Results: Three experts confirmed the relevance and appropriateness of each item. All items and total scores for adherence (intraclass correlation coefficients [ICC]=0.76–1.00 and competence (ICC=0.78–0.98 yielded good to excellent inter-rater reliability. Cronbach's alpha was 0.59 for the adherence scale and 0.96 for the competence scale. Conclusions: The scales reliably assess adherence and competence in D-CPT for adolescent PTSD patients. The ratings can be helpful in the interpretation of treatment effects, the assessment of mediator variables, and the identification and training of therapeutic skills that are central to achieving good treatment outcomes. Both adherence and competence will be assessed as possible predictor variables for treatment success in future D-CPT trials.

  9. Painfully reassuring? The effects of validation on emotions and adherence in a pain test.

    Linton, S J; Boersma, K; Vangronsveld, K; Fruzzetti, A

    2012-04-01

    Communicating reassurance to patients with musculoskeletal pain complaints, but no red flags, presents a dilemma of dampening worry while refraining from reinforcing undue pain behaviors. Previous research shows that reassurance does not decrease negative affect and may be perceived as not taking the symptoms seriously. Validation offers an alternative where the patient's experiences and feelings are acknowledged and has demonstrated, for other problems, a decrease in arousal which may set the stage for behavioral change. The purpose of this study was to investigate experimentally whether validation, as compared to invalidation, impacts on emotions and adherence during repeated pain tests. To this end, 50 participants were randomized to either a validation or invalidation condition. Each participant was told they would undergo four pain trials involving holding a bucket at arm's length to tolerance. During the inter-trial interval, the experimenter provided validating or invalidating responses according to the randomization. As a proxy measure of adherence subjects were asked to engage in an additional pain test. Results indicated that validation relative to invalidation resulted in significantly more positive affect and significantly less worry. Both groups had reductions in negative affect over the trials, but there were no difference between the groups on negative affect or pain. However, adherence was more than twice as high in the validation group as compared to invalidation. These results show that a relatively simple validation procedure had significant and positive effects on emotion and increased adherence. Further research should extend these findings and explore their clinical application.

There is limited representative information on ART drug adherence and its associated factors from Southern Ethiopia. We aimed at estimating the level of adherence to ART among people living with HIV and factors associated with it in 20 randomly selected ART clinics of Southern Ethiopia.Methods: In this cross-sectional study, we interviewed consecutive HIV patients on first-line antiretroviral regimen attending the clinics in June 2014 using a pretested and structured questionnaire. For measuring adherence, we used 4-day recall method based on “The AIDS Clinical Trial Group adherence assessment tool”. Patients were classified as “Incomplete adherence” if they missed any of the doses in the last 4 days. Data were singly entered using EpiData and descriptive analysis, and unadjusted odds ratios were calculated using EpiDataStat software. Multivariate logistic regression analysis was performed using Stata v12.0.Results: Of 974 patients interviewed, 539 (56% were females, and mean age was 35 years. The proportion of patients with incomplete adherence was 13% (95% confidence interval: 11%–15

    2010-03-01

    Full Text Available Objective: To describe the education, research, practice, and policy related to pharmacist interventions to improve medication adherence in community settings in the United States.Methods: Authors used MEDLINE and International Pharmaceutical Abstracts (since 1990 to identify community and ambulatory pharmacy intervention studies which aimed to improve medication adherence. The authors also searched the primary literature using Ovid to identify studies related to the pharmacy teaching of medication adherence. The bibliographies of relevant studies were reviewed in order to identify additional literature. We searched the tables of content of three US pharmacy education journals and reviewed the American Association of Colleges of Pharmacy website for materials on teaching adherence principles. Policies related to medication adherence were identified based on what was commonly known to the authors from professional experience, attendance at professional meetings, and pharmacy journals.Results: Research and Practice: 29 studies were identified: 18 randomized controlled trials; 3 prospective cohort studies; 2 retrospective cohort studies; 5 case-controlled studies; and one other study. There was considerable variability in types of interventions and use of adherence measures. Many of the interventions were completed by pharmacists with advanced clinical backgrounds and not typical of pharmacists in community settings. The positive intervention effects had either decreased or not been sustained after interventions were removed. Although not formally assessed, in general, the average community pharmacy did not routinely assess and/or intervene on medication adherence. Education: National pharmacy education groups support the need for pharmacists to learn and use adherence-related skills. Educational efforts involving adherence have focused on students’ awareness of adherence barriers and communication skills needed to engage patients in behavioral

    Poor adherence to medication is a major public health challenge. Here, we aimed to determine the adherence to oral and topical medications and to analyze underlying associated factors using the translated Japanese version of Morisky Medication Adherence Scale-8 regarding urticaria treatment. Web-based questionnaires were performed for 3096 registered dermatological patients, along with a subanalysis of 751 registered urticaria patients in this study. The adherence to oral medication was significantly associated with the frequency of hospital visits. Variables that affected the adherence to topical medication included age and experience of drug effectiveness. The rate of responses that "It felt like the symptoms had improved" varied significantly among the dermatological diseases treated with oral medications. Dermatologists should be aware that adherence to the treatment of urticaria is quite low. Regular visits and active education for patients with urticaria are mandatory in order to achieve a good therapeutic outcome by increasing the adherence.

  13. Assessing antiretroviral adherence via electronic drug monitoring and self-report: an examination of key methodological issues.

    Pearson, Cynthia R; Simoni, Jane M; Hoff, Peter; Kurth, Ann E; Martin, Diane P

    2007-03-01

    We explored methodological issues related to antiretroviral adherence assessment, using 6 months of data collected in a completed intervention trial involving 136 low-income HIV-positive outpatients in the Bronx, NY. Findings suggest that operationalizing adherence as a continuous (versus dichotomous) variable and averaging adherence estimates over multiple assessment points (versus using only one) explains greater variance in HIV-1 RNA viral load (VL). Self-reported estimates provided during a phone interview accounted for similar variance in VL as EDM estimates (R (2) = .17 phone versus .18 EDM). Self-reported adherence was not associated with a standard social desirability measure, and no difference in the accuracy of self-report adherence was observed for assessment periods of 1-3 days. Self-reported poor adherence was more closely associated with EDM adherence estimates than self-reported moderate and high adherence. On average across assessment points, fewer than 4% of participants who reported taking a dose of an incorrect amount of medication.

    Full Text Available Michael L Scanlon,1,2 Rachel C Vreeman1,21Department of Pediatrics, Indiana University School of Medicine, Indianapolis, IN, USA; 2USAID, Academic Model Providing Access to Healthcare (AMPATH Partnership, Eldoret, KenyaAbstract: The rollout of antiretroviral therapy (ART significantly reduced human immunodeficiency virus (HIV-related morbidity and mortality, but good clinical outcomes depend on access and adherence to treatment. In resource-limited settings, where over 90% of the world’s HIV-infected population resides, data on barriers to treatment are emerging that contribute to low rates of uptake in HIV testing, linkage to and retention in HIV care systems, and suboptimal adherence rates to therapy. A review of the literature reveals limited evidence to inform strategies to improve access and adherence with the majority of studies from sub-Saharan Africa. Data from observational studies and randomized controlled trials support home-based, mobile and antenatal care HIV testing, task-shifting from doctor-based to nurse-based and lower level provider care, and adherence support through education, counseling and mobile phone messaging services. Strategies with more limited evidence include targeted HIV testing for couples and family members of ART patients, decentralization of HIV care, including through home- and community-based ART programs, and adherence promotion through peer health workers, treatment supporters, and directly observed therapy. There is little evidence for improving access and adherence among vulnerable groups such as women, children and adolescents, and other high-risk populations and for addressing major barriers. Overall, studies are few in number and suffer from methodological issues. Recommendations for further research include health information technology, social-level factors like HIV stigma, and new research directions in cost-effectiveness, operations, and implementation.

    Full Text Available Suzanne C Lareau1, Barbara P Yawn21College of Nursing, University of Colorado Denver, Aurora, Colorado; 2Department of Research, Olmsted Medical Center, Rochester, Minnesota, USAAbstract: Chronic obstructive pulmonary disease (COPD is a major public health problem, associated with considerable morbidity and health care costs. The global burden of COPD morbidity is predicted to rise substantially in the coming decade, but could be moderated by better use of existing management strategies. Smoking cessation, medication therapy, and pulmonary rehabilitation have all been shown to diminish morbidity and improve patient outcomes. But each of these strategies requires adherence. Adherence is crucial for optimizing clinical outcomes in COPD, with nonadherence resulting in a significant health and economic burden. Suboptimal medication adherence is common among COPD patients, due to a number of factors that involve the medication, the delivery device, the patient, and the health professionals caring for the patient. Lack of medication adherence needs to be identified and addressed by using simplified treatment regimens, increasing patient knowledge about self-management, and enhancing provider skills in patient education, communication, and adherence counseling. This article reports some of the challenges of medication nonadherence faced by the clinician in the management of COPD, and suggests ways to evaluate and improve adherence effectively in primary care.Keywords: chronic obstructive pulmonary disease, adherence, clinician

    Full Text Available Introduction. Appropriate adherence to medication is still a challenging issue for hypertensive patients. We determined adherence to antihypertensive(s and its associated factors among 280 Iranian patients. Methods. They were recruited consecutively from private and university health centers and pharmacies in four cities. The validated Persian version of the 8-item Morisky Medication Adherence Scale (MMAS-8 was administered to measure adherence. Results. Mean (±SD overall MMAS-8 score was 5.75 (±1.88. About half of the sample (139 cases, 49.6% showed low adherence (MMAS-8 score < 6. There was a negative linear association between the MMAS-8 score and systolic BP (r=-0.231, P<0.001 as well as diastolic BP (r=-0.280, P<0.001. In linear regression model, overweight/obesity (B=-0.52, P=0.02, previous history of admission to emergency services due to hypertensive crisis (B=-0.79, P=0.001, and getting medication directly from drugstore without refill prescription in hand (B=-0.51, P=0.04 were factors recognized to have statistically significant association with the MMAS-8 score. Conclusion. Antihypertensive adherence was unsatisfactory. We suggest that health care providers pay special attention and make use of the aforementioned findings in their routine visits of hypertensive patients to recognize those who are vulnerable to poor adherence.

  18. Efficacy and safety of a multifactor intervention to improve therapeutic adherence in patients with chronic obstructive pulmonary disease (COPD: protocol for the ICEPOC study

    2011-02-01

    Full Text Available Abstract Background Low therapeutic adherence to medication is very common. Clinical effectiveness is related to dose rate and route of administration and so poor therapeutic adherence can reduce the clinical benefit of treatment. The therapeutic adherence of patients with chronic obstructive pulmonary disease (COPD is extremely poor according to most studies. The research about COPD adherence has mainly focussed on quantifying its effect, and few studies have researched factors that affect non-adherence. Our study will evaluate the effectiveness of a multifactor intervention to improve the therapeutic adherence of COPD patients. Methods/Design A randomized controlled clinical trial with 140 COPD diagnosed patients selected by a non-probabilistic method of sampling. Subjects will be randomly allocated into two groups, using the block randomization technique. Every patient in each group will be visited four times during the year of the study. Intervention: Motivational aspects related to adherence (beliefs and behaviour: group and individual interviews; cognitive aspects: information about illness; skills: inhaled technique training. Reinforcement of the cognitive-emotional aspects and inhaled technique training will be carried out in all visits of the intervention group. Discussion Adherence to a prescribed treatment involves a behavioural change. Cognitive, emotional and motivational aspects influence this change and so we consider the best intervention procedure to improve adherence would be a cognitive and emotional strategy which could be applied in daily clinical practice. Our hypothesis is that the application of a multifactor intervention (COPD information, dose reminders and reinforcing audiovisual material, motivational aspects and inhalation technique training to COPD patients taking inhaled treatment will give a 25% increase in the number of patients showing therapeutic adherence in this group compared to the control group. We will

    AIM: To evaluate the impact of therapeutic education on adherence to antiviral treatment and sustained virological response (SVR) in a real-life setting in genotype 2/3 hepatitis C, as there are few adherence data in genotype 2/3 infection, even from randomized trials. METHODS: This prospective survey included genotype 2/3 patients who received peg-interferon alfa-2b and ribavirin. There was no intervention. Adherence was self-reported over the past 4 wk (peg-interferon) or 7 d (ribavirin). Adherence to bitherapy was defined as adherence to the two drugs for≥20 wk. SVR was defined as undetectable RNA≥12 wk after the end of treatment. RESULTS: 370/674 patients received education during the first 3 mo of treatment. After 6 mo, adherence to bitherapy was higher in educated patients (61% vs 47%, P=0.01). Adherence to peg-interferon was 78% vs 69% (P=0.06). Adherence to ribavirin was 70% vs 56% (P=0.006). The SVR (77% vs 70%, P = 0.05) and relapse (10% w 16%, P = 0.09) rates tended to be improved. After adjustment for baseline differences, education improved adherence [Odds ratio (OR) 1.58, P=0.04] but not the SVR (OR 1.54, P=0.06). CONCLUSION: In genotype 2/3 patients, therapeutic education helped maintain real-life adherence to bitherapy.

    Engagement with care for those living with HIV is aimed at establishing a strong relationship between patients and their health care provider and is often associated with greater adherence to therapy and treatment (Flickinger, Saha, Moore, and Beach, 2013). Substance use behaviors are linked with lower rates of engagement with care and medication adherence (Horvath, Carrico, Simoni, Boyer, Amico, and Petroli, 2013). This study is a secondary data analysis using a cross-sectional design from a larger randomized controlled trial (n = 775) that investigated the efficacy of a self-care symptom management manual for participants living with HIV. Participants were recruited from countries of Africa and the US. This study provides evidence that substance use is linked with lower self-reported engagement with care and adherence to therapy. Data on substance use and engagement are presented. Clinical implications of the study address the importance of utilizing health care system and policy factors to improve engagement with care.

    Background and Introduction: Mobile applications are useful tools to improve medication adherence. As developers continue to improve the features of existing mobile applications, pharmacists should be aware of the current features that are available to patients. There are limited studies available that discuss which applications have the most desirable features. The aim of this study was to compare available mobile applications and identify ideal application features used to improve medication adherence.

    2014-06-01

    Full Text Available OBJECTIVE To estimate rates of non-adherence to telemedicine strategies aimed at treating drug addiction. METHODS A systematic review was conducted of randomized controlled trials investigating different telemedicine treatment methods for drug addiction. The following databases were consulted between May 18, 2012 and June 21, 2012: PubMed, PsycINFO, SciELO, Wiley (The Cochrane Library, Embase, Clinical trials and Google Scholar. The Grading of Recommendations Assessment, Development and Evaluation was used to evaluate the quality of the studies. The criteria evaluated were: appropriate sequence of data generation, allocation concealment, blinding, description of losses and exclusions and analysis by intention to treat. There were 274 studies selected, of which 20 were analyzed. RESULTS Non-adherence rates varied between 15.0% and 70.0%. The interventions evaluated were of at least three months duration and, although they all used telemedicine as support, treatment methods differed. Regarding the quality of the studies, the values also varied from very poor to high quality. High quality studies showed better adherence rates, as did those using more than one technique of intervention and a limited treatment time. Mono-user studies showed better adherence rates than poly-user studies. CONCLUSIONS Rates of non-adherence to treatment involving telemedicine on the part of users of psycho-active substances differed considerably, depending on the country, the intervention method, follow-up time and substances used. Using more than one technique of intervention, short duration of treatment and the type of substance used by patients appear to facilitate adherence.

The CAPER-capecitabine trial is closely related to the CAPER-erlotinib trial.Discussion: The aim of the present study is to get more insight into patient experiences with the use of capecitabine in daily practice and the various aspects that govern adherence. We hypothesize that patient attitudes towards medication and the side effects experienced play an important role in the way patients use capecitabine. We expect that our findings will be useful for health care professionals in developing interventions to support patients in improving adherence and persistence with the use of capecitabine.Keywords: capecitabine, medication adherence, patients' experiences, medical oncology, oral antineoplastic agents

  7. Effect of a Multi-Dimensional and Inter-Sectoral Intervention on the Adherence of Psychiatric Patients.

    Anne Pauly

    Full Text Available In psychiatry, hospital stays and transitions to the ambulatory sector are susceptible to major changes in drug therapy that lead to complex medication regimens and common non-adherence among psychiatric patients. A multi-dimensional and inter-sectoral intervention is hypothesized to improve the adherence of psychiatric patients to their pharmacotherapy.269 patients from a German university hospital were included in a prospective, open, clinical trial with consecutive control and intervention groups. Control patients (09/2012-03/2013 received usual care, whereas intervention patients (05/2013-12/2013 underwent a program to enhance adherence during their stay and up to three months after discharge. The program consisted of therapy simplification and individualized patient education (multi-dimensional component during the stay and at discharge, as well as subsequent phone calls after discharge (inter-sectoral component. Adherence was measured by the "Medication Adherence Report Scale" (MARS and the "Drug Attitude Inventory" (DAI.The improvement in the MARS score between admission and three months after discharge was 1.33 points (95% CI: 0.73-1.93 higher in the intervention group compared to controls. In addition, the DAI score improved 1.93 points (95% CI: 1.15-2.72 more for intervention patients.These two findings indicate significantly higher medication adherence following the investigated multi-dimensional and inter-sectoral program.German Clinical Trials Register DRKS00006358.

    SMS is a widely used technology globally and may also improve ART adherence, yet SMS notifications to social supporters following real-time detection of missed doses showed no clear benefit in a recent pilot trial. We examine the demographic and social-cultural dynamics that may explain this finding. In the trial, 63 HIV-positive individuals initiating ART received a real-time adherence monitor and were randomized to two types of SMS reminder interventions versus a control (no SMS). SMS notifications were also sent to 45 patient-identified social supporters for sustained adherence lapses. Like participants, social supporters were interviewed at enrollment, following their matched participant's adherence lapse and at exit. Social supporters with regular income (RR = 0.27, P = 0.001) were significantly associated with fewer adherence lapses. Instrumental support was associated with fewer adherence lapses only among social supporters who were food secure (RR = 0.58, P = 0.003). Qualitative interview data revealed diverse and complex economic and relationship dynamics, affecting social support. Resource availability in emotionally positive relationships seemingly facilitated helpful support, while limited resources prevented active provision of support for many. Effective social support appeared subject to social supporters' food security, economic stability and a well-functioning social network dependent on trust and supportive disclosure.

    2015-08-01

    The Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) obtained a sample of 1493 chronic schizophrenia patients. The European First Episode Schizophrenia Trial (EUFEST) studied a sample of 498 patients. We have combined these two samples to study the predictors and correlates of adherence to treatment. Here we report on adherence to pharmacological treatment at the six and twelve month assessments of these trials with a combined subsample of 1154 schizophrenia patients. Individual patients׳ data were used for analyses. We used logistic regression to examine the effects of substance use, akathisia, parkinsonism, dyskinesia, hostility, and insight on pharmacological adherence. The results showed that reduced adherence to pharmacological treatment was associated with substance use (p=0.0003), higher levels of hostility (p=0.0002), and impaired insight (p<0.0001). Furthermore, poor adherence to study medication was associated with earlier discontinuation in the combined data. The clinical implications of the results point to the importance of routine assessments and interventions to address patients׳ insight and comorbid substance use and the establishment of therapeutic alliance.

    2015-09-01

    Researchers have instituted a range of methodologies to increase access to HIV adherence interventions. This article reviews studies published through January 2014 utilizing computer-based delivery of such interventions to persons living with HIV. A systematic review of five databases identified ten studies (three RCTs, three pilot studies, three feasibility studies, and one single-group trial) that met the inclusion criteria. Descriptions of the interventions' content and characteristics are included. Interventions varied widely in terms of program structure, theoretical framework, and content. Only six studies reported medication adherence outcomes. Of these, four (five RCTS and one single group pre-post test) reported significant improvement in adherence using various measures, and two approached significance. Results suggest that computer-delivered adherence interventions are feasible and acceptable among both HIV-positive adolescents and adults. Definitive conclusions regarding clinical impact cannot be drawn due to the small number of adequately powered randomized trials in this review. Additional randomized controlled research is needed to draw inferences regarding intervention efficacy.

    Food insecurity and malnutrition negatively affect adherence to antiretroviral therapy (ART) and are associated with poor HIV clinical outcomes. We examined the effect of providing household food assistance and nutrition education on ART adherence. A 12-month prospective clinical trial compared the effect of a monthly household food basket (FB) plus nutrition education (NE) versus NE alone on ART adherence on 400 HIV patients at four clinics in Honduras. Participants had been receiving ART for an average of 3.7 years and were selected because they had suboptimal adherence. Primary outcome measures were missed clinic appointments, delayed prescription refills, and self-reported missed doses of ART. These three adherence measures improved for both groups over 12 months (p < 0.01), mostly within 6 months. On-time prescription refills improved for the FB plus NE group by 19.6 % more than the group receiving NE alone after 6 months (p < 0.01), with no further change at 12 months. Change in missed appointments and self-reported missed ART doses did not significantly differ by intervention group.

    2015-12-01

    Full Text Available Background: Donepezil is indicated for the management of mild to moderate dementia, particularly in Alzheimer's disease. Several studies have described low adherence rates with donepezil. Aim: To examine and measure donepezil adherence, persistence and time to first discontinuation in older New Zealanders. Methods: An inception cohort of 1,999 new users of donepezil, aged 65 years or older, were identified from the Pharmaceutical Collections and National Minimum Dataset from 1 November 2010 to 31 December 2013. Kaplan-Meier curves and Cox regression analysis were used to estimate the cumulative probability and risk of time to first discontinuation of donepezil therapy. Results: The mean age of the cohort was 79.5 ± 6.4 years and included 42.7% females. Adherence was high (89.0%, while the proportion of donepezil dispensings (81.0-32.5% declined between 6 and 36 months. Persistence between the 1st and 6th dispensing visit decreased by 19.0%, and 11.0% of the total cohort had a gap of 31 days or more. The adjusted risk of time to first discontinuation in the non-adherent group was 2.2 times (95% CI 1.9-2.6 that of the adherent group. Conclusions: The non-adherent new donepezil users, on average, discontinued faster than the adherent group. Time to first discontinuation in this study was higher compared to discontinuation rates observed in clinical trials.

    Background Secondary prevention is cost-effective for cardiovascular disease (CVD), but uptake is suboptimal. Understanding barriers and facilitators to adherence to secondary prevention for CVD at multiple health system levels may inform policy. Objectives To conduct a systematic review of barriers and facilitators to adherence/persistence to secondary CVD prevention medications at health system level. Methods Included studies reported effects of health system level factors on adherence/persistence to secondary prevention medications for CVD (coronary artery or cerebrovascular disease). Studies considered at least one of β blockers, statins, angiotensin–renin system blockers and aspirin. Relevant databases were searched from 1 January 1966 until 1 October 2015. Full texts were screened for inclusion by 2 independent reviewers. Results Of 2246 screened articles, 25 studies were included (12 trials, 11 cohort studies, 1 cross-sectional study and 1 case–control study) with 132 140 individuals overall (smallest n=30, largest n=63 301). 3 studies included upper middle-income countries, 1 included a low middle-income country and 21 (84%) included high-income countries (9 in the USA). Studies concerned established CVD (n=4), cerebrovascular disease (n=7) and coronary heart disease (n=14). Three studies considered persistence and adherence. Quantity and quality of evidence was limited for adherence, persistence and across drug classes. Studies were concerned with governance and delivery (n=19, including 4 trials of fixed-dose combination therapy, FDC), intellectual resources (n=1), human resources (n=1) and health system financing (n=4). Full prescription coverage, reduced copayments, FDC and counselling were facilitators associated with higher adherence. Conclusions High-quality evidence on health system barriers and facilitators to adherence to secondary prevention medications for CVD is lacking, especially for low-income settings.

    Full Text Available Objetive: The primary objective of this study was to evaluate the adherence level in chronic conditions patients during “The Adherence Day” celebrated on November 15, 2013. Methods: We performed a transversal, observational and multicenter study at 43 Spanish hospitals, in order to estimate adherence in chronic treatments. We used the validated questionnaires Haynes- Sackett and Morisky- Green to measure medication adherence; but also a visual analogue scale and questions related with treatment complexity and selective adherence were applied. We performed a descriptive analysis and the closeness of agreement between questionnaires results. Results: A total of 723 surveys were collected especially among outpatients. 43% of the participants were women, with a median age of 51 and taking 3 drugs per day. 10.8% of the patients reported to have difficulty taking their pills according to Haynes- Sackett test. However, depending on Morisky- Green questionnaire, 56.4% of the participants were totally compliant; but considering only the question about forgetfulness, more were adherents (77%. 71% of the patients considered their compliance level as good (more than 8 according to visual analogue scale. And 11% presented a selective adherence, no taking equally well all the medications. The closeness of agreement between questionnaires and Morisky- Green test, as gold standard, was poor for Haynes- Sackett and weak for visual analogue scale. Conclusions: In our study only 56% of the patients with chronic treatment had a perfect adherence

The aim of this study was to examine the FHL among older adults and identify influencing factors that can predict medication adherence. Methods: This was a cross-sectional survey. Participants (n=160 aged 65 years and older were selected from outpatient clinics of 3 tertiary care hospitals, 6 community pharmacies, and 2 senior centers between November 1 and 30, 2014. The participants’ FHL was measured using the Korean Functional Health Literacy Test, which consists of 15 items including 8 numeracy and 7 reading comprehension items. Medication adherence was measured by the Adherence to Refills and Medication Scale. Descriptive statistics, chi-square or Fisher’s exact test, and multiple regression analyses were used to analyze the data. Results: The mean score of the total FHL was 7.72±3.51 (range 0–15. The percentage of the total number of correct answers for the reading comprehension subtest and numeracy subtest were 48.1% and 54.4%, respectively. Among 160 participants, 52.5% showed low adherence to medication. The factors affecting medication adherence included the patient’s degree of satisfaction with the service (β=-0.215, P=0.022, sufficient explanation of medication counseling (β=-0.335, P=0.000, education level (β=-0.153, P=0.045, health-related problems (β=-0.239, P=0.004, and dosing frequency (β=0.189, P=0.018. Conclusion: In this study, we found medication adherence of elderly patients was associated with education level, health-related problems, dosing frequency, satisfaction with patient counseling, and explanation of medication, but no association was found with FHL.

    Ellenberg, Susan S; Culbertson, Richard; Gillen, Daniel L; Goodman, Steven; Schrandt, Suzanne; Zirkle, Maryan

    2015-10-01

    In any clinical trial, it is essential to monitor the accumulating data to be sure that the trial continues to be safe for participants and that the trial is being conducted properly. Data monitoring committees, independent expert panels who undertake regular reviews of the data as the trial progresses, serve an important role in safeguarding the interests of research participants and ensuring trial integrity in many trials. Many pragmatic clinical trials, which aim to inform healthcare decisions by comparing alternate interventions in heterogeneous healthcare delivery settings, will warrant review by an independent data monitoring committee due to their potential impact on clinical practice. However, the very features that make a trial "pragmatic" may pose challenges in terms of which aspects of a trial to monitor and when it is appropriate for a data monitoring committee to intervene. Using the Pragmatic-Explanatory Continuum Indicator Summary tool that draws distinctions between pragmatic and explanatory clinical trials, we review characteristics of pragmatic clinical trials that may have implications for data monitoring committees and interim monitoring plans. These include broad eligibility criteria, a focus on subjective patient-centered outcomes, and in some cases a lack of standardized follow-up procedures across study sites. Additionally, protocol adherence is often purposefully not addressed in pragmatic trials in order to accurately represent the clinical practice setting and maintain practicability of implementation; there are differing viewpoints as to whether adherence should be assessed and acted upon by data monitoring committees in these trials. Some other issues not specifically related to the Pragmatic-Explanatory Continuum Indicator Summary criteria may also merit special consideration in pragmatic trials. Thresholds for early termination of a pragmatic clinical trial might be controversial. The distinguishing features of pragmatic clinical

    2016-01-01

    Background Adherence to effective Web-based interventions for common mental disorders (CMDs) and well-being remains a critical issue, with clear potential to increase effectiveness. Continued identification and examination of “active” technological components within Web-based interventions has been called for. Gamification is the use of game design elements and features in nongame contexts. Health and lifestyle interventions have implemented a variety of game features in their design in an effort to encourage engagement and increase program adherence. The potential influence of gamification on program adherence has not been examined in the context of Web-based interventions designed to manage CMDs and well-being. Objective This study seeks to review the literature to examine whether gaming features predict or influence reported rates of program adherence in Web-based interventions designed to manage CMDs and well-being. Methods A systematic review was conducted of peer-reviewed randomized controlled trials (RCTs) designed to manage CMDs or well-being and incorporated gamification features. Seven electronic databases were searched. Results A total of 61 RCTs met the inclusion criteria and 47 different intervention programs were identified. The majority were designed to manage depression using cognitive behavioral therapy. Eight of 10 popular gamification features reviewed were in use. The majority of studies utilized only one gamification feature (n=58) with a maximum of three features. The most commonly used feature was story/theme. Levels and game leaders were not used in this context. No studies explicitly examined the role of gamification features on program adherence. Usage data were not commonly reported. Interventions intended to be 10 weeks in duration had higher mean adherence than those intended to be 6 or 8 weeks in duration. Conclusions Gamification features have been incorporated into the design of interventions designed to treat CMD and well

  5. Parent Adherence in Two Behavioral Treatment Strategies for the Predominantly Inattentive Presentation of ADHD.

    2016-11-03

    We examined the effects of parent adherence on child outcomes in two treatment strategies for the Predominantly Inattentive Presentation of attention deficit/hyperactivity disorder (ADHD-I): behavioral parent training adapted for ADHD-I (Parent-Focused Therapy [PFT]) and a multicomponent intervention that combined PFT, a child life skills group, and a classroom intervention (Child Life and Attention Skills Program [CLAS]). In a 2-site randomized controlled trial, 199 children (7-11 years of age) were randomized to PFT (n = 74), CLAS (n = 74), or treatment as usual (n = 51). Parent adherence was rated separately by parents and clinicians. Child outcomes included ADHD-I symptoms and parent- and teacher- rated impairment social, organizational, and home impairment. Results from multiple regression analyses utilizing a composite of parent and clinician ratings showed that parent adherence predicted improvement in all 3 parent-rated child impairment outcomes and no teacher-rated outcomes in the PFT treatment group. Adherence ratings did not predict any parent- or teacher-rated outcomes in the CLAS treatment group and did not predict ADHD symptom change in either treatment condition. These findings suggest that when parents are solely responsible for teaching and reinforcing new child skills and behaviors (as in PFT), their adherence to the assigned intervention may be especially important for improvement at home. It may be less critical in multicomponent interventions, like CLAS, where the responsibility for teaching new child skills is shared among parents, teachers, and child group clinicians. Parent adherence does not appear to impact child improvement in the school setting.

    Full Text Available Adherence to treatment of diabetes mellitus (DM can support successful therapy due to drug consumption over longtime periods. The objectives of this study are to evaluate the treatment adherence in DM as related to the quality of life and to evaluate factors associated with adherence and quality of life. This study used the Brief Medication Questionnaire (BMQ to measure patients’ adherence. The Diabetes Quality of Life Clinical Trial Questionnaire (DQLCTQ was used to measure patients’ quality of life. Subjects of this cross-sectional study were DM patients attending two private hospitals in Yogyakarta and who had been taking DM medications for more than 6 months. Statistical analyses used in this study were student’s t test and regression linear test. We recruited 65 DM patients who met the inclusion criteria. There were no significant differences of BMQ screens and DQLCTQ functions between monotherapy and combination therapy groups (p> .05. The BMQ screens’ score of combination therapy were higher than monotherapy groups. The physical function, health distress, and mental health of combination therapy groups were higher than monotherapy group. The male patients had significantly higher score of regimen domain of BMQ than female patients (0.35 and 0.17, respectively. The older age has the lower score of treatment effect of DQLCTQ (p< .05. The belief, recall, and belief about adverse drug reaction of BMQ have positive correlation with physical function (r = .542, .424, and .640, respectively. Our study concluded that the quality of care, sex, and age may predict patients’ adherence and quality of life. There were positive correlation between patients’ adherence and quality of life.

    Full Text Available ABSTRACT: BACKGROUND: In spite of any number of medicines will not be of use unless patient takes’ them. After diagnosing the disease, the next most i mportant step is to follow the instructions of physician in terms of treatment. The doctor’s respons ibility does not end with writing prescription, assuming patient will adhere to it. He/ she should cross check the behavior of patient for drug compliance and see that patient follo ws it and get the benefit. Non compliance is the main barrier for the effective delivery of the medical care. This will have greater implications on the economic burde n on the country in terms of frequent hospitalization, use of expensive medicines in case o f relapse due to non adherence.Though the terms compliance and adherence are used synonymously , they differ in the delivery of quality of the medicare as the former implicates the passive fol lowing of the physician instruction, while in the later, patient actively participates in the dev elopment of the treatment plan, which will improves outcome of the treatment. Adherence is the preferred term over compliance by WHO.

  11. Non-adherence in difficult asthma and advances in detection.

    Lindsay, John T; Heaney, Liam G

    2013-12-01

    Non-adherence to anti-inflammatory therapies is common in patients referred for specialist assessment at difficult-to-treat asthma services. In the difficult asthma setting, non-adherence to treatment is associated with poor baseline asthma control, increased frequency of exacerbations and asthma-related hospitalizations, as well as increased risk of death. Here, we present a review of the current literature surrounding the prevalence and risks of non-adherence in difficult asthma and we report on current methods of measuring treatment adherence and advances in the detection of non-adherence. We will also explore methods by which non-adherence in difficult asthma can be addressed.

    The aim of this study was to evaluate Staphylococcus sp adhesion to modified surfaces of anodized titanium alloy (Ti-6Al-4V). Surface modification involved generation of fluoride-containing titanium oxide nanotube films. Specimens of Ti-6Al-4V alloy 6-4 ELI-grade 23- meets the requirements of ASTM F136 2002A (AMS 2631B class A1) were anodized in a mixture of sulphuric/hydrofluoric acid at 20 V for 5 and 60 min to form a 100 nm-thick porous film of 20 nm pore diameter and 230 nm-thick nanotube films of 100 nm in diameter. The amount of fluorine in the oxide films was of 6% and of 4%, respectively. Collection strains and six clinical strains each of Staphylococcus aureus and Staphylococcus epidermidis were studied. The adherence study was performed using a previously published protocol by Kinnari et al. The experiments were performed in triplicates. As a result, lower adherence was detected for collection strains in modified materials than in unmodified controls. Differences between clinical strains were detected for both species (p<0.0001, Kruskal-Wallis test), although global data showed similar results to that of collection strains (p<0.0001, Kruskal-Wallis test). Adherence of bacteria to modified surfaces was decreased for both species. The results also reflect a difference in the adherence between S. aureus and S. epidermidis to the modified material. As a conclusion, not only we were able to confirm the decrease of adherence in the modified surface, but also the need to test multiple clinical strains to obtain more realistic microbiological results due to intraspecies differences.

  13. Experiencing antiretroviral adherence: helping healthcare staff better understand adherence to paediatric antiretrovirals

    Phelps Benjamin R

    2010-12-01

    Full Text Available Abstract Background Lack of adherence to antiretroviral medications is one of the key challenges for paediatric HIV care and treatment programmes. There are few hands-on opportunities for healthcare workers to gain awareness of the psychosocial and logistic challenges that caregivers face when administering daily antiretroviral therapy to children. This article describes an educational activity that allows healthcare workers to simulate this caregiver role. Methods Paediatric formulations of several antiretroviral medications were dispensed to a convenience sample of staff at the Baylor College of Medicine-Bristol-Myers Squibb Children's Clinical Center of Excellence in Mbabane, Swaziland. The amounts of the medications remaining were collected and measured one week later. Adherence rates were calculated. Following the exercise, a brief questionnaire was administered to all staff participants. Results The 27 clinic staff involved in the exercise had varying and low adherence rates over the week during which the exercise was conducted. Leading perceived barriers to adherence included: "family friends don't help me remember/tell me I shouldn't take it" and "forgot". Participants reported that the exercise was useful as it allowed them to better address the challenges faced by paediatric patients and caregivers. Conclusions Promoting good adherence practices among caregivers of children on antiretrovirals is challenging but essential in the treatment of paediatric HIV. Participants in this exercise achieved poor adherence rates, but identified with many of the barriers commonly reported by caregivers. Simulations such as this have the potential to promote awareness of paediatric ARV adherence issues among healthcare staff and ultimately improve adherence support and patient outcomes.

  14. Ensuring medication adherence with direct oral anticoagulant drugs: lessons from adherence with vitamin K antagonists (VKAs).

    Di Minno, Alessandro; Spadarella, Gaia; Tufano, Antonella; Prisco, Domenico; Di Minno, Giovanni

    2014-05-01

    Medication adherence (taking drugs properly) is uncommon among patients on warfarin. Poor adherence to warfarin leads to an increase in adverse medical events, including stroke in atrial fibrillation (AF). Factors related to patients, physicians and the health system account for poor adherence. Direct oral anticoagulants (DOACs) are easier to use than warfarin, with fewer drug and food interactions and no need for routine blood monitoring. A proper use of DOACs may reduce the risk of stroke in AF. However, in clinical settings where no laboratory monitoring is needed, a poor medication adherence is common and may impact clinical outcomes. In the management of chronic disorders, careful knowledge of the individual patient's attitudes and behaviors is a pre-requisite for a successful doctor-patient communication. To increase patient's awareness of the risks and benefits of DOACs and, in turn, increase medication adherence, at each follow-up visit physicians should screen for priorities and motivational problems; check for the lack of understanding and/or knowledge; assess any health system or personal barriers to medication adherence; identify appropriate interventions and provide tailored support to patient needs. Dissemination of guidelines to the health care chain (prescribing physician, general practitioners, caregivers, nurses, pharmacists) further encourages medication adherence. However, the long-term effect of some of these strategies is unknown; one tool may not fit all patients, and the prescribing physician should consider individualization of these aids to ensure medication adherence and persistence (continuing to take drugs properly in long-term treatments) for DOACs in every day practice.

    2012-01-01

    Full Text Available Background. Evidence suggests adherence to clinical guidelines for pelvic inflammatory disease (PID diagnosis and management is suboptimal. We systematically reviewed the literature for studies describing strategies to improve the adherence to PID clinical guidelines. Methods. The databases MEDLINE and EMBASE, and reference lists of review articles were searched from January 2000 to April 2012. Only studies with a control group were included. Results. An interrupted time-series study and two randomised controlled trials (RCTs were included. The interrupted time-series found that following a multifaceted patient and practitioner intervention (practice protocol, provision of antibiotics on-site, written instructions for patients, and active followup, more patients received the recommended antibiotics and attended for followup. One RCT found a patient video on PID self-care did not improve medication compliance and followup. Another RCT found an abbreviated PID treatment guideline for health-practitioners improved their management of PID in hypothetical case scenarios but not their diagnosis of PID. Conclusion. There is limited research on what strategies can improve practitioner and patient adherence to PID diagnosis and management guidelines. Interventions that make managing PID more convenient, such as summary guidelines and provision of treatment on-site, appear to lead to better adherence but further empirical evidence is necessary.

  17. Paying for antiretroviral adherence: is it unethical when the patient is an adolescent?

    Healy, Justin; Hope, Rebecca; Bhabha, Jacqueline; Eyal, Nir

    2017-03-01

    With the expansion of antiretroviral treatment programmes, many children and adolescents with HIV in sub-Saharan Africa could expect to live healthy lives. Yet adolescents have the highest levels of poor antiretroviral adherence and of loss to follow-up compared with other age groups. This can lead to increased morbidity and mortality, to the development of drug-resistant strains, and to high societal costs. While financial incentives have been extensively used to promote medication adherence among adults, their use among adolescents remains rare. And while there is a large body of ethical literature exploring financial incentives among adults, little philosophical thought has gone into their use among adolescents. This paper explores three oft-mentioned ethical worries about financial incentives for health behaviours and it asks whether these concerns are more serious in the context of incentives for improving adolescent adherence. The three worries are that such incentives would unduly coerce adolescents' decision-making, would compromise distributive justice and would crowd out intrinsic motivations and non-monetary values. Our tentative conclusion is that more empirical investigation of these concerns is necessary, and that at this point they are not compelling enough to rule out trials in which adolescents are incentivised for antiretroviral adherence.

  18. Adherence of Moraxella bovis to cell cultures of bovine origin.

    Annuar, B O; Wilcox, G E

    1985-09-01

    The adherence of five strains of Moraxella bovis to cell cultures was investigated. M bovis adhered to cultures of bovine corneal epithelial and Madin-Darby bovine kidney cells but not to cell types of non-bovine origin. Both piliated and unpiliated strains adhered but piliated strains adhered to a greater extent than unpiliated strains. Antiserum against pili of one strain inhibited adherence of piliated strains but caused only slight inhibition of adherence to the unpiliated strains. Treatment of bacteria with magnesium chloride caused detachment of pili from the bacterial cell and markedly inhibited adherence of piliated strains but caused only slight inhibition of adherence by the unpiliated strains. The results suggested that adhesion of piliated strains to cell cultures was mediated via pili but that adhesins other than pili may be involved in the attachment of unpiliated strains of M bovis to cells.

    Full Text Available Administering drugs as fixed-dose combinations (FDCs versus the same active drugs administered as separate pills is assumed to enhance treatment adherence. We synthesized evidence from randomized controlled trials (RCTs about the effect of FDCs versus separate pills on adherence. We searched PubMed for RCTs comparing a FDC with the same active drugs administered as separate pills, including a quantitative estimate of treatment adherence, without restriction to medical condition. The odds ratio (OR of optimal adherence with FDCs versus separate pills was used as common effect size and aggregated into a pooled effect estimate using a random effect model with inverse variance weights. Out of 1258 articles screened, only six studies fulfilled inclusion criteria. Across medical conditions, administering drugs as FDC significantly increased the likelihood of optimal adherence (OR 1.33 (95% CI, 1.03–1.71. Within subgroups of specific medical conditions, the favourable effect of FDCs on adherence was of borderline statistical significance for HIV infection only (OR 1.46 (95% CI, 1.00–2.13. We observed a remarkable paucity of RCTs comparing the effect on adherence of administering drugs as FDC versus as separate pills. Administering drugs as FDC improved medication adherence. However, this conclusion is based on a limited number of RCTs only.

Despite this, non-adherence with medication is prevalent in PD. Treatments for improving adherence with medication have been investigated in many chronic conditions, including PD. However, few researchers have evaluated their interventions qualitatively. We investigated the acceptability and potential mechanism of action of adherence therapy (AT in PD patients and their spouse/carers who received the intervention as part of a randomized controlled trial. Methods: Sixteen participants (ten patients and six spouses/carers who had recently completed the trial were purposely selected in order to cover a range of ages and disease severity. Semi-structured interviews were conducted in the participants’ homes. Data were transcribed and analyzed using a thematic approach. A second researcher, naïve to PD and AT, analyzed the data independently to limit bias. Results: The trial showed that AT significantly improved both medication adherence and quality of life in people with PD. Specifically, patients who received AT reported improvements in mobility, activities of daily living, emotional wellbeing, cognition, communication, and body discomfort. General beliefs about medication also significantly improved in those who received AT compared with controls. In the current qualitative evaluation, a

Patients’ satisfaction with their treatment is an important consideration for physicians. Strategies like using longer acting efficacious agents with less frequent dosing may help adherence. Objective: To explore the mode of administration of dulaglutide and its implications for treatment adherence in T2DM. Methods: PubMed search using the term “Dulaglutide” through October 31, 2015 was conducted. Published articles, press releases, and abstracts presented at national/international meetings were considered. Results/conclusion: Dulaglutide is a once-weekly glucagon like peptide-1 analog with a low intraindividual variability. Phase III trials demonstrated significant improvements in glycemia and weight, with a low hypoglycemia risk similar to liraglutide/exenatide, but with substantially fewer injections. A significant improvement was observed in the total Diabetes Treatment Satisfaction Questionnaire score, Impact of Weight on Self-Perception, and perceived frequency of hyperglycemia with dulaglutide when compared with placebo, exenatide, liraglutide, or metformin. Treatment satisfaction scores showed an improvement with dulaglutide (34%–39% when compared with exenatide (31%. A positive experience with a high initial (97.2% and final (99.1% injection success rate along with a significant reduction in patients’ fear of self-injecting, as measured by the modified self-injecting subscale of the Diabetes Fear of Injecting and Self-Testing Questionnaire and Medication Delivery Device Assessment Battery, was found.

  6. Understanding how adherence goals promote adherence behaviours: a repeated measure observational study with HIV seropositive patients

    Jones Gareth

    2012-08-01

    Full Text Available Abstract Background The extent to which patients follow treatments as prescribed is pivotal to treatment success. An exceptionally high level (> 95% of HIV medication adherence is required to suppress viral replication and protect the immune system and a similarly high level (> 80% of adherence has also been suggested in order to benefit from prescribed exercise programmes. However, in clinical practice, adherence to both often falls below the desirable level. This project aims to investigate a wide range of psychological and personality factors that may lead to adherence/non-adherence to medical treatment and exercise programmes. Methods HIV positive patients who are referred to the physiotherapist-led 10-week exercise programme as part of the standard care are continuously recruited. Data on social cognitive variables (attitude, intention, subjective norms, self-efficacy, and outcome beliefs about the goal and specific behaviours, selected personality factors, perceived quality of life, physical activity, self-reported adherence and physical assessment are collected at baseline, at the end of the exercise programme and again 3 months later. The project incorporates objective measures of both exercise (attendance log and improvement in physical measures such as improved fitness level, weight loss, improved circumferential anthropometric measures and medication adherence (verified by non-invasive hair analysis. Discussion The novelty of this project comes from two key aspects, complemented with objective information on exercise and medication adherence. The project assesses beliefs about both the underlying goal such as following prescribed treatment; and about the specific behaviours such as undertaking the exercise or taking the medication, using both implicit and explicit assessments of patients’ beliefs and attitudes. We predict that i the way people think about the underlying goal of their treatments explains medication and exercise

  12. Medication adherence among older adults with schizophrenia.

    Leutwyler, Heather C; Fox, Patrick J; Wallhagen, Margaret

    2013-02-01

    Older adults with schizophrenia are a growing segment of the population, yet their physical and mental health status is extremely poor. This article presents findings from a qualitative study that explored the understanding older adults with schizophrenia have of their physical health status. The study was conducted among 28 older adults with schizophrenia from a variety of settings using semi-structured interviews and participant observation. Self-management of psychiatric and non-psychiatric medications and its effect on participants' health status was one of the central themes that emerged from the study. Different styles of medication adherence were identified and factors associated with each style are presented. The findings provide insights into the design of clinical interventions aimed at promoting medication adherence among older adults with schizophrenia.

  18. Adherence to asthma guidelines in general practices.

    Roghmann, M C; Sexton, M

    1999-06-01

    Adherence to asthma practice guidelines is low. Improved compliance could potentially improve care of patients with asthma. The purpose of this study was to determine if patients managed in a general practice with an associated asthma clinic are more likely to use asthma medications according to clinical practice guidelines than patients managed in the general surgery of the practice. A cross-sectional study of adult asthmatics, aged 18-55 years, was conducted in six British general practices. Prescription data on all asthma medication was collected for a 6-month period. Information on asthma clinic attendance, age, sex, employment status, other medical illness, and how patients used their inhaled beta2-agonist was collected through questionnaire. The prescription data for asthma medication and patient use of inhaled beta2-agonist were compared to the British Thoracic Society's (BTS) Guidelines for Management of Asthma in Adults to determine if the patient's asthma medication regimen was appropriate. There was no significant association found between appropriate asthma medication and asthma clinic attendance or other patient characteristics. Adherence to the BTS guidelines was low. Fifty-eight percent of the asthma patients used asthma medication regimens that were not consistent with the BTS guidelines published 1 year earlier. Adherence to the BTS guidelines was low regardless of patient characteristics, including asthma clinic attendance, age, sex, employment status, other medical illness, or individual practice. These findings underscore the need to document the utility of clinical practice guidelines which may improve physician compliance.

    2006-07-01

    This article focuses on the magnitude of the challenge of heart failure, with particular reference to the disease burden in Spain. The text also deals with the difficulty of estimating the size of the problem, which stems from the fact that heart failure is a common end-point of numerous conditions. The second part of the article presents some reflections on the value of clinical practice guidelines and on the difficulty of incorporating interventions that have proven their efficacy under the controlled conditions of a clinical trial into everyday clinical practice, thereby maximizing their potential benefits. Finally, some suggestions are made on improving both professionals' adherence to clinical practice guidelines and patients' adherence to recommended treatment.

    Marguerite Clyne

    1997-01-01

    Full Text Available Bacterial adhesion to the intestinal epithelium is a critical initial step in the pathogenesis of many enteric diseases. Helicobacter pylori is a duodenal pathogen that adheres to the gastric epithelium and causes gastritis and peptic ulceration. The mechanism by which H pylori causes disease has not yet been elucidated but adherence to the gastric mucosa is thought to be an important virulence determinant of the organism. What is known about adherence of H pylori to the gastric mucosa is summarized. Topics discussed are the mechanism of H pylori adherence; in vitro and in vivo models of H pylori infection; and adherence and potential adhesins and receptors for H pylori.

  2. Adherence Characteristics of Cement Clinker on Basic Bricks

    GUO Zongqi; Michel Rigaud

    2002-01-01

    Based on the sandwich test, adherence mechanisms of cement clinker on various basic bricks were tackled by microstructural observations with help of cathodoluminescence technique. Doloma based bricks offer sufficient lime to react with clinker, forming C3 S rich layer and initializing superior adherence. However, clinker with low silica ratio leads to MgO agglomeration at the interface of doloma bricks, which reduces adherence strength. On magnesia spinel bricks, fine, crystalline spinel easily reacts with lime containing phases from clinker to form lowmelting phases and belite zone, which shows high adherence performance. Lack of fine spinel in magnesia spinel bricks results in poor adherence.

    Full Text Available A random survey of 100 representative mosques in the U.S. was conducted to measure the correlation between Sharia adherence and dogma calling for violence against non-believers.  Of the 100 mosques surveyed, 51% had texts on site rated as severely advocating violence; 30% had texts rated as moderately advocating violence; and 19% had no violent texts at all.  Mosques that presented as Sharia adherent were more likely to feature violence-positive texts on site than were their non-Sharia-adherent counterparts.  In 84.5% of the mosques, the imam recommended studying violence-positive texts.  The leadership at Sharia-adherent mosques was more likely to recommend that a worshipper study violence-positive texts than leadership at non-Sharia-adherent mosques.  Fifty-eight percent of the mosques invited guest imams known to promote violent jihad.  The leadership of mosques that featured violence-positive literature was more likely to invite guest imams who were known to promote violent jihad than was the leadership of mosques that did not feature violence-positive literature on mosque premises.

    The Thalassemia Clinical Research Network collected adherence information from 79 patients on deferoxamine and 186 on deferasirox from 2007 to 2009. Chelation adherence was defined as percent of doses administered in the last 4 weeks (patient report) out of those prescribed (chart review). Chelation history since 2002 was available for 97 patients currently on deferoxamine and 217 on deferasirox, with crude estimates of adherence from chart review. Self-reported adherence to both deferoxamine and deferasirox were quite high, with slightly higher adherence to the oral chelator (97 vs. 92%). Ninety percent of patients on deferasirox reported at least 90% adherence, compared with 75% of patients on deferoxamine. Adherence to both chelators was highest in children, followed by adolescents and older adults. Predictors of lower deferoxamine adherence were smoking in the past year, problems sticking themselves (adults only), problems wearing their pump, and fewer transfusions in the past year. Predictors of lower deferasirox adherence were bodily pain and depression. Switching chelators resulted in increased adherence, regardless of the direction of the switch, although switching from deferoxamine to deferasirox was far more common. As adherence to deferoxamine is higher than previously reported, it appears beneficial for patients to have a choice in chelators. PMID:21523808

Patient perceptions about the necessity of the prescribed medication to treat osteoporosis and the concerns about the potential adverse effects are important and potentially modifiable determinants of adherence, in addition to other factors, such as difficult dosing regimens and high dosing frequency. Denosumab (Dmab is a fully human monoclonal antibody against the receptor activator of nuclear factor-κB ligand (RANKL, which, through the prevention of the RANKL/RANK interaction, inhibits osteoclast-mediated bone resorption and significantly reduces the risk of vertebral, nonvertebral, and hip fractures. It is administered subcutaneously every 6 months for the treatment of postmenopausal osteoporosis. Preference and adherence to Dmab treatment were assessed in various clinical trials. Although with some limitations, available data suggest that Dmab is preferred to bisphosphonates, produces greater satisfaction than bisphosphonates, and would be preferentially chosen for long-term treatment. Moreover, patient perceptions about the necessity of Dmab treatment clearly outweigh the concerns about the injections, and positive beliefs about treatment positively influence medication-taking behavior. According to these data, Dmab may represent a reasonable alternative to bisphosphonates, particularly for osteoporotic women in whom a suboptimal or even poor adherence to oral treatments is expected.

  9. A fully automated system for adherent cells microinjection.

    Becattini, Gabriele; Mattos, Leonardo S; Caldwell, Darwin G

    2014-01-01

    This paper proposes an automated robotic system to perform cell microinjections to relieve human operators from this highly difficult and tedious manual procedure. The system, which uses commercial equipment currently found on most biomanipulation laboratories, consists of a multitask software framework combining computer vision and robotic control elements. The vision part features an injection pipette tracker and an automatic cell targeting system that is responsible for defining injection points within the contours of adherent cells in culture. The main challenge is the use of bright-field microscopy only, without the need for chemical markers normally employed to highlight the cells. Here, cells are identified and segmented using a threshold-based image processing technique working on defocused images. Fast and precise microinjection pipette positioning over the automatically defined targets is performed by a two-stage robotic system which achieves an average injection rate of 7.6 cells/min with a pipette positioning precision of 0.23 μm. The consistency of these microinjections and the performance of the visual targeting framework were experimentally evaluated using two cell lines (CHO-K1 and HEK) and over 500 cells. In these trials, the cells were automatically targeted and injected with a fluorescent marker, resulting in a correct cell detection rate of 87% and a successful marker delivery rate of 67.5%. These results demonstrate that the new system is capable of better performances than expert operators, highlighting its benefits and potential for large-scale application.

  10. Pharmacy adherence measures to assess adherence to antiretroviral therapy: review of the literature and implications for treatment monitoring.

    Prescription or pill-based methods for estimating adherence to antiretroviral therapy (ART), pharmacy adherence measures (PAMs), are objective estimates calculated from routinely collected pharmacy data. We conducted a literature review to evaluate PAMs, including their association with virological and other clinical outcomes, their efficacy compared with other adherence measures, and factors to consider when selecting a PAM to monitor adherence. PAMs were classified into 3 categories: medication possession ratio (MPR), pill count (PC), and pill pick-up (PPU). Data exist to recommend PAMs over self-reported adherence. PAMs consistently predicted patient outcomes, but additional studies are needed to determine the most predictive PAM parameters. Current evidence suggests that shorter duration of adherence assessment (≤ 6 months) and use of PAMs to predict future outcomes may be less accurate. PAMs which incorporate the number of days for which ART was prescribed without the counting of remnant pills, are reasonable minimum-resource methods to assess adherence to ART.

  11. A counselor in your pocket: feasibility of mobile health tailored messages to support HIV medication adherence

    Full Text Available Paul F Cook,1 Jane M Carrington,2 Sarah J Schmiege,1 Whitney Starr,3 Blaine Reeder11University of Colorado College of Nursing, Aurora, CO, USA; 2University of Arizona College of Nursing, Tucson, AZ, USA; 3University of Colorado School of Medicine, Aurora, CO, USAPurpose: Medication adherence is a major challenge in HIV treatment. New mobile technologies such as smartphones facilitate the delivery of brief tailored messages to promote adherence. However, the best approach for tailoring messages is unknown. Persons living with HIV (PLWH might be more receptive to some messages than others based on their current psychological state.Methods: We recruited 37 PLWH from a parent study of motivational states and adherence. Participants completed smartphone-based surveys at a random time every day for 2 weeks, then immediately received intervention or control tailored messages, depending on random assignment. After 2 weeks in the initial condition, participants received the other condition in a crossover design. Intervention messages were tailored to match PLWH’s current psychological state based on five variables – control beliefs, mood, stress, coping, and social support. Control messages were tailored to create a mismatch between message framing and participants’ current psychological state. We evaluated intervention feasibility based on acceptance, ease of use, and usefulness measures. We also used pilot randomized controlled trial methods to test the intervention’s effect on adherence, which was measured using electronic caps that recorded pill-bottle openings.Results: Acceptance was high based on 76% enrollment and 85% satisfaction. Participants found the hardware and software easy to use. However, attrition was high at 59%, and usefulness ratings were slightly lower. The most common complaint was boredom. Unexpectedly, there was no difference between mismatched and matched messages’ effects, but each group showed a 10%–15% improvement

  12. Adherence to Mediterranean diet and bone health

    Antonio Romero Pérez

    2014-05-01

    Full Text Available Introduction: Several studies have concluded that incidences of osteoporosis and osteoporosis-related fractures vary across the European Union, the lowest incidence being reported in the Mediterranean area. The beneficial effect is mainly attributed to a specific eating pattern. The Mediterranean diet contain a complex array of naturally occurring bioactive molecules with antioxidant, anti-inflammatory and alkalinising properties that may contribute to the bone-sparing effect of the Mediterranean diet. Objective: The purpose of this review is to examine the evidence to date on the effects of Mediterranean diet on bone health. Methods: The search for articles came from extensive research in the following databases: PubMed, Scopus and Web of Science. We used the search terms "Mediterranean diet", "adherence", "fruit and vegetable", "olive oil", "fish" "legume", "cereal" "alcohol", "bone", "osteoporosis", "fracture", and combinations, such as "Mediterranean diet and bone" or "Mediterranean diet and fracture". Results: A limited number of studies have examined the relationship between Mediterranean Diet and bone health, and they have reported conflicting results. On the one hand, adherence to a traditional MeDi has been associated with higher bone mineral density and lower fracture risk. The results of these studies could be attributed to the combined beneficial effects of individual components of the Mediterranean diet. On the contrary, several studies failed to show any association between adherence to the MeDi and indices of bone mass. Conclusions: Further large-scale studies are required to clarify the effect of Mediterranean diet on bone health, in order to establish the role of this diet in the prevention of osteoporosis.

  13. On World Religion Adherence Distribution Evolution

    Ausloos, Marcel; Petroni, Filippo

    Religious adherence can be considered as a degree of freedom, in a statistical physics sense, for a human agent belonging to a population. The distribution, performance and life time of religions can thus be studied having in mind heterogeneous interacting agent modeling. We present a comprehensive analysis of 58 so-called religions (to be better defined in the main text) as measured through their number of adherents evolutions, between 1900 and 2000, - data taken from the World Christian Trends (Barrett and Johnson, "World Christian Trends AD 30 - AD 2200: Interpreting the Annual Christian Megacensus", William Carey Library, 2001): 40 are considered to be "presently growing" cases, including 11 turn overs in the twentieth century; 18 are "presently decaying", among which 12 are found to have had a recent maximum, in the nineteenth or the twentieth century. The Avrami-Kolmogorov differential equation which usually describes solid state transformations, like crystal growth, is used in each case in order to obtain the preferential attachment parameter introduced previously (Europhys Lett 77:38002, 2007). It is not often found close to unity, though often corresponding to a smooth evolution. However large values suggest the occurrence of extreme cases which we conjecture are controlled by so-called external fields. A few cases indicate the likeliness of a detachment process. We discuss a few growing and decaying religions, and illustrate various fits. Some cases seem to indicate the lack of reliability of the data, but others some marked departure from Avrami law. Whence the Avrami evolution equation might be surely improved, in particular, and somewhat obviously, for the decaying religion cases. We point out two major difficulties in such an analysis: (1) the "precise" original time of apparition of a religion, (2) the time at which there is a maximum number of adherents, both information being necessary for integrating reliably any evolution equation.

    2013-01-01

    Full Text Available Background: Acquired immune deficiency syndrome (AIDS is now considered as a manageable chronic illness. There has been a dramatic reduction in human immunodeficiency virus (HIV related morbidity and mortality due to antiretroviral therapy. A high level of adherence (>95% is required for antiretroviral therapy to be effective. There are many barriers to adherence in both developed and developing countries. Aim: The aim of our study was to determine adherence levels and factors influencing adherence to antiretroviral therapy among people living with HIV. Materials and Methods: Using a cross-sectional study design, 116 HIV positive patients receiving antiretroviral therapy for at least 1 year were interviewed using a semi structured questionnaire. The collected data was analyzed using Statistical Product and Service Solutions (SPSS version 11.5. Chi-square test was done. A P value of < 0.05 was considered statistically significant. Results: Of 116 participants, 63.7% reported adherence ≥ 95%. Mean adherence index was 91.25%. Financial constraints, forgetting to take medication, lack of family care, depression, alcohol use, social stigma and side effects to antiretroviral therapy were barriers for adherence in our study. Conclusion: Adherence to antiretroviral therapy in south India is suboptimal. Intensive adherence counseling should be provided to all patients before initiation ofantiretroviral therapy. Health care providers must identify possible barriers to adherence at the earliest and provide appropriate solutions.

  16. Patient adherence to medical treatment: a review of reviews

    Heerdink Rob

    2007-04-01

    Full Text Available Abstract Background Patients' non-adherence to medical treatment remains a persistent problem. Many interventions to improve patient adherence are unsuccessful and sound theoretical foundations are lacking. Innovations in theory and practice are badly needed. A new and promising way could be to review the existing reviews of adherence to interventions and identify the underlying theories for effective interventions. That is the aim of our study. Methods The study is a review of 38 systematic reviews of the effectiveness of adherence interventions published between 1990 and 2005. Electronic literature searches were conducted in Medline, Psychinfo, Embase and the Cochrane Library. Explicit inclusion and exclusion criteria were applied. The scope of the study is patient adherence to medical treatment in the cure and care sector. Results Significant differences in the effectiveness of adherence interventions were found in 23 of the 38 systematic reviews. Effective interventions were found in each of four theoretical approaches to adherence interventions: technical, behavioural, educational and multi-faceted or complex interventions. Technical solutions, such as a simplification of the regimen, were often found to be effective, although that does not count for every therapeutic regimen. Overall, our results show that, firstly, there are effective adherence interventions without an explicit theoretical explanation of the operating mechanisms, for example technical solutions. Secondly, there are effective adherence interventions, which clearly stem from the behavioural theories, for example incentives and reminders. Thirdly, there are other theoretical models that seem plausible for explaining non-adherence, but not very effective in improving adherence behaviour. Fourthly, effective components within promising theories could not be identified because of the complexity of many adherence interventions and the lack of studies that explicitly compare

  1. Statistical Dynamics of Religions and Adherents

    Ausloos, M; Ausloos, Marcel; Petroni, Filippo

    2006-01-01

    Religiosity is one of the most important sociological aspects of populations. All religions may evolve in their beliefs and adapt to the society developments. A religion is a social variable, like a language or wealth, to be studied like any other organizational parameter. Several questions can be raised, as considered in this study: e.g. (i) from a ``macroscopic'' point of view : How many religions exist at a given time? (ii) from a ``microscopic'' view point: How many adherents belong to one religion? Does the number of adherents increase or not, and how? No need to say that if quantitative answers and mathematical laws are found, agent based models can be imagined to describe such non-equilibrium processes. It is found that empirical laws can be deduced and related to preferential attachment processes, like on evolving network; we propose two different algorithmic models reproducing as well the data. Moreover, a population growth-death equation is shown to be a plausible modeling of evolution dynamics in a...

  2. Automated microinjection system for adherent cells

    Youoku, Sachihiro; Suto, Yoshinori; Ando, Moritoshi; Ito, Akio

    2007-07-01

    We have developed an automated microinjection system that can handle more than 500 cells an hour. Microinjection injects foreign agents directly into cells using a micro-capillary. It can randomly introduce agents such as DNA, proteins and drugs into various types of cells. However, conventional methods require a skilled operator and suffer from low throughput. The new automated microinjection techniques we have developed consist of a Petri dish height measuring method and a capillary apex position measuring method. The dish surface height is measured by analyzing the images of cells that adhere to the dish surface. The contrast between the cell images is minimized when the focus plane of an object lens coincides with the dish surface. We have developed an optimized focus searching method with a height accuracy of +/-0.2 um. The capillary apex position detection method consists of three steps: rough, middle, and precise. These steps are employed sequentially to cover capillary displacements of up to +/-2 mm, and to ultimately accomplish an alignment accuracy of less than one micron. Experimental results using this system we developed show that it can introduce fluorescent material (Alexa488) into adherent cells, HEK293, with a success rate of 88.5%.

  4. Side effects, adherence self-efficacy, and adherence to antiretroviral treatment: a mediation analysis in a Chinese sample.

    Zhang, Liying; Li, Xiaoming; Lin, Zhenping; Jacques-Tiura, Angela J; Xu, Jinping; Zhou, Yuejiao; Qiao, Shan; Shen, Zhiyong; Stanton, Bonita

    Antiretroviral therapy (ART) is a lifelong treatment. To date, ART adherence is suboptimal for most patients in resource-poor settings. Previous research indicates that medication side effects are perceived to be a significant barrier of high ART adherence. Data regarding the role of adherence self-efficacy in mediating the relationship between side effects from ART and adherence to ART are limited; thus, this study examines this potential mediational role of self-efficacy. A cross-sectional survey of 2987 people living with HIV aged ≥18 years was conducted in 2012-2013 in Guangxi Autonomous Region (Guangxi) which has one of the fastest-growing HIV rates in China. Of the total sample, 2146 (72.1%) participants had initiated ART. Participants reported the number of days of completing the daily dose of ART in the past month; adherence was defined as completing the daily dose at least 28 days in the last month (≥90%). Side effects were significantly negatively related to adherence to ART. Mediation analyses indicated that adherence self-efficacy significantly mediated the side effects-adherence relationship. Future interventions to increase adherence self-efficacy and effective coping with side effects among HIV patients are needed in order to improve their ART adherence.

  5. Stability of adherence to highly active antiretroviral therapy over time among clients enrolled in the treatment adherence demonstration project.

    2003-08-01

    Adherence to antiretroviral medications is essential to therapeutic success. Many published studies have investigated the degree of adherence or nonadherence, but sample sizes have generally been small, and adherence has seldom been viewed as a longitudinal process. This paper investigates the stability of adherence over time among HIV-infected individuals attending adherence support programs in New York State. The study cohort consists of 435 clients who were on HAART at baseline and who completed at least 2 follow-up interviews. Although cross-sectional nonadherence did not exceed 35%, nonadherence reached 54% when considered across all 3 interviews. Analysis of transition matricies revealed moderate stability in adherence over time (e.g., first follow-up adherence was 81.0% for clients adherent at baseline, compared with 58.3% for clients nonadherent at baseline). Second-order transition matricies offered additional predictive utility. Multivariate results indicated that, for some, it was the transition from a desirable to an undesirable state (e.g., from no illicit drug use to illicit drug use) that increased the likelihood of nonadherence, rather than the presence of these characteristics over time. Findings illustrate the importance of multiple, periodic assessments of adherence and the need to consider strategies to increase stability in the factors affecting adherence to HAART.

    Poor adherence to medication is one of the most important determinants in the treatment of patients with chronic disorders. e-Health-based interventions may be able to improve treatment adherence. This article gives an overview of the available e-Health interventions and the extent to which they can improve adherence. We searched in the PubMed, Cinahl, PsycInfo, and Embase databases for e-Health interventions that aimed at improving adherence to treatment. Of the 16 included studies, 15 used a website and one used an app. Ten studies showed a significant improvement in treatment adherence by using the intervention. e-Health interventions were generally complex. Simple interventions were the most successful in improving treatment adherence.

  7. Measuring insulin adherence among adults with type 2 diabetes.

    Osborn, Chandra Y; Gonzalez, Jeffery S

    2016-08-01

    Non-adherence to insulin is common and associated with suboptimal health. We adapted the Morisky Medication Adherence Scale to specify insulin adherence (MIAS) and compared it to the Adherence to Refills and Medication Scale for Diabetes (ARMS-D) and the Summary of Diabetes Self-Care Activities medications subscale (SDSCA-MS) and an insulin-specific (SDSCA-IS) version. A sample of 144 insulin-treated adults (58 % African American/Black, 34 % Caucasian/White, 8 % Other/Mixed race; 6.9 % Hispanic) completed these measures along with a HbA1C test. The internal consistency and factor structure of the MIAS were adequate; 59 % of participants forgot to take insulin and 46 % reported non-adherence. The MIAS was associated with the ARMS-D, SDSCA-MS, and SDSCA-IS (p insulin adherence assessment tool for practice and research applications.

    Kawakami, Aki; Tanaka, Makoto; Naganuma, Makoto; Maeda, Shin; Kunisaki, Reiko; Yamamoto-Mitani, Noriko

    2017-01-01

    Background Overall, 30%–45% of patients with ulcerative colitis (UC) are non-adherent and have difficulties taking their medications; this non-adherence increases the risk of clinical relapse 1.4- to 5.5-fold. This study aimed to clarify the strategies patients employ to facilitate adherence and determine whether the strategies had an impact on good adherence. Methods This was a cross-sectional survey using a self-administered questionnaire and review of medical records. Patients diagnosed as having UC and attending one of the outpatient clinics of four urban hospitals from June 2009 to December 2012 were enrolled. A questionnaire was developed to identify the strategies patients employ to facilitate adherence and then administered to patients with UC. Adherence to 5-aminosalicylic acid was calculated, and univariate and multiple logistic regression analyses were performed to determine the strategies that were associated with good adherence. Results The final analyses included 671 participants (mean age 40.2 years; 54.3% males). The valid response rate was 96.9%; 186 (27.7%) participants were classified as non-adherent, the mean adherence rate being 86.1% (standard deviation [SD] 17.9). Seven strategies that patients employ to facilitate adherence were identified, the following two being significantly associated with good adherence: “I keep my medicines where I eat meals” and “I keep each day’s medicine in a pill case or something similar to make sure I have taken them”. Conclusion The identified strategies might be used to develop a program to improve medication adherence in patients with UC. PMID:28203059

    HIV-positive women are at elevated risk for developing cervical cancer. While emerging research suggests that gynecologic health care is underutilized by HIV-positive women, factors associated with adherence to Pap testing, especially among HIV-positive female smokers are not well known. We utilized baseline data from a smoking cessation trial and electronic medical records to assess Pap smear screening prevalence and the associated characteristics among the HIV-positive female participants (n = 138). 46 % of the women had at least 1 Pap test in the year following study enrollment. Multiple logistic regression analysis indicated that younger age, African American race, hazardous drinking, increased number of cigarettes smoked per day, and smoking risk perception were associated with non-adherence to Pap smear screening. Cervical cancer screening was severely underutilized by women in this study. Findings underscore the importance of identifying predictors of non-adherence and addressing multiple risk factors and behavioral patterns among HIV-positive women who smoke.

  11. The role of family caregivers in HIV medication adherence.

    Beals, K P; Wight, R G; Aneshensel, C S; Murphy, D A; Miller-Martinez, D

    2006-08-01

    This study examines the role that mid-life and older wives and mothers play in promoting medication adherence among their HIV-infected husbands or adult sons who require daily living assistance. Interviews were conducted with 112 caregiving dyads, with caregivers reporting on their own behaviours and attitudes towards medications, and care-recipients (persons living with HIV [PLH]) providing information about their own adherence practices. By examining how caregiver characteristics, behaviours, and attitudes may influence PLH adherence it is explicitly recognized that caregivers and PLH are linked within a caregiving dyad. Findings indicate that caregivers often remind PLH to take medications, but these reminders are not significantly associated with adherence. Caregivers also report strong attitudes about medication hassles, concerns over treatment failure and general concerns about adherence. Controlling for background characteristics, high perceived adherence hassles on the part of the caregiver were associated with low PLH adherence, providing evidence of shared influence within the caregiving dyad. Adherence interventions may maximize their effectiveness if they consider the role of the family caregiver because these data suggest that caregiver attitudes are linked with PLH adherence behaviours.

    This study aims to identify potential factors that could affect adherence and influence the implementation of an evidence-based structured walking program, among older adults diagnosed with knee osteoarthritis. A total of 69 participants with mild to moderate osteoarthritis of the knee fulfilled an online survey on potential factors that could affect their adherence to an evidence-based structured walking program. Adherence with regard to the influencing factors was explored using a logistic regression model. Results tend to show higher odds of adhering to the evidence-based walking program if the participants were supervised (more than 2.9 times as high), supported by family/friends (more than 3.7 times as high), and not influenced by emotional involvement (more than 11 times as high). The odds of adhering were 3.6 times lower for participants who indicated a change in their medication intake and 3.1 times lower for individuals who considered themselves as less physically active (95 % confidence interval (CI)). Our exploratory findings identified and defined potential adherence factors that could guide health professionals in their practice to better identify positive influences and obstacles to treatment adherence, which would lead to the adoption of a more patient-centered approach. A large-scale study is required to clearly delineate the key factors that would influence adherence. We addressed a new knowledge gap by identifying the main strategies to promote the long-term adherence of community-based walking program.

  13. Impact of prescription size on statin adherence and cholesterol levels

    Mehler Phillip S

    2007-10-01

    Full Text Available Abstract Background Therapy with 3-Hydroxy-3-methylglutaryl Co-enzyme A reductase inhibitors (statins improve outcomes in a broad spectrum of patients with hyperlipidemia. However, effective therapy requires ongoing medication adherence; restrictive pharmacy policies may represent a barrier to successful adherence, particularly among vulnerable patients. In this study we sought to assess the relationship between the quantity of statin dispensed by the pharmacy with patient adherence and total cholesterol. Methods We analyzed a cohort of 3,386 patients receiving more than one fill of statin medications through an integrated, inner-city health care system between January 1, 2000 and December 31, 2002. Our measure of adherence was days of drug acquisition divided by days in the study for each patient, with adequate adherence defined as ≥ 80%. Log-binomial regression was used to determine the relative risk of various factors, including prescription size, on adherence. We also assessed the relationship between adherence and total cholesterol using multiple linear regression. Results After controlling for age, gender, race, co-payment, comorbidities, and insurance status, patients who obtained a majority of fills as 60-day supply compared with 30-day supply were more likely to be adherent to their statin medications (RR 1.41, 95% CI 1.28–1.55, P Conclusion In a healthcare system serving predominantly indigent patients, the provision of a greater quantity of statin medication at each prescription fill contributes to improved adherence and greater drug effectiveness.

    2007-01-01

    Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.

  18. Adherence to Pre-Exposure Prophylaxis for HIV Prevention in a Clinical Setting.

    Madeline C Montgomery

    Full Text Available The HIV epidemic in the United States (US disproportionately affects gay, bisexual, and other men who have sex with men (MSM. Pre-exposure prophylaxis (PrEP using co-formulated tenofovir disoproxil fumarate (TDF and emtricitabine (FTC has demonstrated high efficacy in reducing HIV incidence among MSM. However, low adherence was reported in major efficacy trials and may present a substantial barrier to successful PrEP implementation. Rates of adherence to PrEP in "real-world" clinical settings in the US remain largely unknown.We reviewed demographic and clinical data for the first 50 patients to enroll in a clinical PrEP program in Providence, Rhode Island. We analyzed self-reported drug adherence as well as drug concentrations in dried blood spots (DBS from patients who attended either a three- or six-month follow-up appointment. We further assessed drug concentrations and the resistance profile of a single patient who seroconverted while taking PrEP.Of the first 50 patients to be prescribed PrEP, 62% attended a follow-up appointment at three months and 38% at six months. Of those who attended an appointment at either time point (70%, n = 35, 92% and 95% reported taking ±4 doses/week at three and six months, respectively. Drug concentrations were performed on a random sample of 20 of the 35 patients who attended a follow-up appointment. TDF levels consistent with ±4 doses/week were found in 90% of these patients. There was a significant correlation between self-reported adherence and drug concentrations (r = 0.49, p = 0.02. One patient who had been prescribed PrEP seroconverted at his three-month follow-up visit. The patient's drug concentrations were consistent with daily dosing. Population sequencing and ultrasensitive allele-specific PCR detected the M184V mutation, but no other TDF- or FTC-associated mutations, including those present as minor variants.In this clinical PrEP program, adherence was high, and self-reported drug adherence

    Full Text Available Chuanwei Xin, Zhongni Xia, Cheng Jiang, Mengmeng Lin, Gonghua Li Department of Pharmacy, Tongde Hospital of Zhejiang Province, Zhejiang Academy of Traditional Chinese Medicine, Hangzhou, People’s Republic of China Background: Poor adherence to insulin medications leads to a high rate of hospital admissions and poor health-related quality of life in the patients with diabetes mellitus. However, few strategies are effective and acceptable in improving medication adherence. The objectives of this study are to evaluate the effectiveness of pharmaceutical care by clinical pharmacists on medication adherence of patients newly prescribed insulin therapy.Patients and methods: A single-center, prospective randomized controlled study (pharmaceutical care group and control group was performed from January 1, 2014 to December 30, 2014. Medication adherence was measured at the baseline and up to 12 months with Morisky–Green test and computerized dispensed medication history. The absolute change in A1c vs baseline, the change of hospitalization between two groups, and the number of patients to achieve Chinese Diabetes Society (CDS goals at the baseline were the main outcome measures.Results: A total of 322 patients were included in the study. After the 12-month interventions, significant improvements in the medication adherence were verified for the pharmaceutical care group according to the Morisky–Green test (50.8% of adherent patients at baseline vs 80.7% of adherent patients after 12-month interventions; P<0.01 and the computerized dispensed medication history (55.2% at baseline vs 83.3% after interventions; P<0.01, while no significant changes were verified in the control group. After follow-up, the pharmaceutical care group showed a greater percent change in A1c (2.2±0.4 vs 0.8±0.2, P<0.05.Conclusion: This study provides new evidence from a randomized controlled trial on the beneficial effect of pharmaceutical care to enhance adherence in

    Full Text Available Danny Decoo,1 Mathieu Vokaer2 1Department of Neurology and Neurorehab, AZ Alma, Sijsele, Belgium; 2Multiple Sclerosis Clinic, Edith Cavell Hospital, CHIREC group, Brussels, Belgium Background: Poor treatment adherence is common among patients with multiple sclerosis (MS. This survey evaluated neurologists’ perception of treatment adherence among MS patients.Materials and methods: This questionnaire-based survey of Belgian neurologists treating MS patients was conducted between June and July 2014. Face-to-face interviews with the neurologists were based on a semistructured questionnaire containing questions regarding the perception of the treatment-adherence level.Results: A total of 41 neurologists participated in the survey. Of these, 88% indicated frequent discussions about treatment adherence as beneficial for treatment efficacy. The mean time spent on the treatment-adherence discussion during the initial consultation was 11 minutes, with 24% of doctors spending 5 minutes and 24% of doctors spending 10 minutes discussing this issue. The majority of neurologists (56% perceived the adherence level in MS as good, and 12% perceived it as excellent. The majority of neurologists (64% indicated intolerance as a main cause of poor adherence, and all neurologists reported insufficient efficacy as a consequence of nonadherence. The importance of adherence in the neurologists’ practice was evaluated on a scale of 1–10, with 1= “not very important” and 10= “very important”: 44% of doctors indicated a score of 10, and the mean score was 9.0.Conclusion: Belgian neurologists consider treatment adherence in MS as essential for the benefits of therapies. However, although neurologists are aware of the consequences of nonadherence, they generally spend limited time discussing the importance of treatment adherence with their patients.

  2. Non-adherence to topical treatments for actinic keratosis

    Shergill, Bav; Zokaie, Simon; Carr, Alison J

    2014-01-01

    Background There is limited information on the patterns of use, adherence rates, and factors that impact adherence with topical treatments for actinic keratosis (AK). Objectives To establish patterns of use and adherence with topical treatments for AK and to identify treatment-related factors that impact on adherence. Methods A community-based, cross-sectional study was performed using a standardized questionnaire completed online or via telephone interview. Patients were stratified according to the presence of AK lesions on the scalp and/or other extremities; and presence of scarring resulting from treatment. Results This study included 305 patients with AK who were currently using a patient-applied topical therapy for AK or had used one within the previous 12 months. In total, 88% (n = 268/305) of patients were either non-adherent, non-persistent or both non-adherent and non-persistent to topical therapy. Duration of treatment was associated with increasing rates of non-adherence (adjusted odds ratio [OR]; for treatment durations greater than 4 weeks, 2.2, P < 0.01): 52% of patients were non-adherent with 3–4 week treatment duration; 69% of patients with 4–8 week treatment duration; and 71% of patients with 6–12 week treatment duration. There were similar increases in non-persistence with increasing treatment duration (adjusted OR; for treatment durations greater than 4 weeks, 2.1, P < 0.05). Conclusion This study found high rates of non-adherence and non-persistence in patients with AK. Duration of treatment was a significant factor contributing to non-adherence and non-persistence to topical treatments. Patient-applied topical therapies that require less frequent application and have shorter treatment duration may be associated with improved adherence rates. PMID:24379656

    Abstract Background: A surge in mobile phone availability has fueled low cost short messaging service (SMS) adherence interventions. Multiple systematic reviews have concluded that some SMS-based interventions are effective at improving antiretroviral therapy (ART) adherence, and they are hypothesized to improve retention in care. The objective of this study was to evaluate the cost-effectiveness of SMS-based adherence interventions and explore the added value of retention benefits. Methods: We evaluated the cost-effectiveness of weekly SMS interventions compared to standard care among HIV+ individuals initiating ART for the first time in Kenya. We used an individual level micro-simulation model populated with data from two SMS-intervention trials, an East-African HIV+ cohort and published literature. We estimated average quality adjusted life years (QALY) and lifetime HIV-related costs from a healthcare perspective. We explored a wide range of scenarios and assumptions in one-way and multivariate sensitivity analyses. Results: We found that SMS-based adherence interventions were cost-effective by WHO standards, with an incremental cost-effectiveness ratio (ICER) of $1,037/QALY. In the secondary analysis, potential retention benefits improved the cost-effectiveness of SMS intervention (ICER = $864/QALY). In multivariate sensitivity analyses, the interventions remained cost-effective in most analyses, but the ICER was highly sensitive to intervention costs, effectiveness and average cohort CD4 count at ART initiation. SMS interventions remained cost-effective in a test and treat scenario where individuals were assumed to initiate ART upon HIV detection. Conclusions: Effective SMS interventions would likely increase the efficiency of ART programs by improving HIV treatment outcomes at relatively low costs, and they could facilitate achievement of the UNAIDS goal of 90% viral suppression among those on ART by 2020.

    We sought to (a) replicate and (b) extend (via the addition of alcohol use) Cha et al.'s cross-sectional multi-component model of ART adherence on the relationship between social support, depression, self-efficacy beliefs, and antiretroviral therapy (ART) adherence, among HIV patients in Tshwane, South Africa. Using purposive sampling, 304 male and female ART recipients were recruited. ART adherence was assessed using three manifest indicators: total adherence ratio, the CASE adherence index and 1-month adherence measure. Data were analysed using structural equation modeling. In our replicated model, social support had both direct and indirect relationships with ART adherence, and inclusion of alcohol use improved prediction of ART adherence. Direct and indirect effects of alcohol use on ART adherence emerged: adherence self-efficacy beliefs partially mediated the latter path. Findings highlight the importance of integrating into ART promotion interventions, the reduction of alcohol use, provision of social support, and enhancement of adherence self-efficacy beliefs.

    2010-01-01

    Platinum compounds are used in the treatment of cancer. We demonstrate that cisplatin-induced (10 µM) apoptosis (caspase-3 activity) is pronounced within 18 hours in non-adherent Ehrlich ascites tumour cells (EATC), whereas there is no increase in caspase-3 activity in the adherent Ehrlich Lettré...... ascites tumour cells (ELA). Loss of KCl and cell shrinkage are hallmarks in apoptosis and has been shown in EATC. However, we find no reduction in cell volume and only a minor loss of K(+) which is accompanied by net uptake of Na(+) following 18 hours cisplatin exposure in ELA. Glutathione and taurine...... have previously been demonstrated to protect cells from apoptosis. We find, however, that increase or decrease in the cellular content of glutathione and taurine has no effect on cisplatin-induced cell death in EATC and ELA. Nevertheless, knock-down of the taurine transporter TauT leads...

    2014-01-01

    Young people represent the largest number of new HIV infections, thus youth living with HIV (YLH) are likely to be the largest group to initiate antiretroviral treatment (ART). Adherence patterns for behaviorally infected YLH are not adequate to effectively manage the disease; therefore, novel interventions are needed to improve medication adherence. The purpose of the current study, which will precede a randomized controlled trial, was to assess the initial feasibility of an individually tailored computer-based two-session interactive motivational interviewing (MI) intervention for YLH newly recommended to start ART. Intervention development occurred in collaboration with three youth advisory groups. Ten youth (ages 18-24) were recruited to participate in this study. Participants completed the intervention online. Intervention components focused on medication adherence (rating perceived importance and confidence, and goal setting). Retention was 100% for both intervention sessions. All participants (n=10) felt medication adherence was important, but 80% felt confident they could manage their adherence to HIV medications. Ninety percent of participants set the goal of taking their HIV medications exactly as prescribed and reported success achieving this goal at follow-up. Additionally, participants were satisfied with the quality of the sessions and the amount of assistance they received for managing their adherence to HIV medications (90% participants for Session 1; 89% for Session 2). Per exit interview responses, participants felt that the intervention made them think more about their health and was a motivator for them to take better care of their health. In conclusion, the intervention was feasible for YLH enrolled in the study.

    Full Text Available Objective: To explore the effect of patient characteristics and health beliefs on their medication adherence. Methods: Patients (n=167 with chronic conditions (mean age 58.9; SD=13.54, 53% males were recruited from March 2009- to March 2010 using a cross sectional study design. Data collected included patients’ demographics, medical conditions, medications therapeutic regimen, frequency of physician visits and health beliefs. Patient self-reported adherence to medications was assessed by the researcher using a validated and published scale. Treatment related problems (TRPs were evaluated for each patient by competent clinical pharmacists. Associations between patient characteristics/health beliefs with adherence were explored. Results: About half of the patients (46.1% were non-adherent. A significant association was found between lower adherence and higher number of disease states (p<0.001, higher number of medications (p=0.001, and higher number of identified TRPs (p = 0.003. Patient adherence was positively affected by older age, higher educational level, and higher number of physician visits per month, while it was negatively affected by reporting difficulties with getting prescription refills on time. Conclusion: This study identified different factors that may negatively affect adherence, including higher number of medications and disease states, higher number of identified TRPs and inability to getting prescription refills on time. Hence, more care needs to be provided to patients with complex therapeutic regimens in order to enhance adherence.

  18. Genetic factors in exercise adoption, adherence and obesity.

    Herring, M P; Sailors, M H; Bray, M S

    2014-01-01

    Physical activity and exercise play critical roles in energy balance. While many interventions targeted at increasing physical activity have demonstrated efficacy in promoting weight loss or maintenance in the short term, long term adherence to such programmes is not frequently observed. Numerous factors have been examined for their ability to predict and/or influence physical activity and exercise adherence. Although physical activity has been demonstrated to have a strong genetic component in both animals and humans, few studies have examined the association between genetic variation and exercise adherence. In this review, we provide a detailed overview of the non-genetic and genetic predictors of physical activity and adherence to exercise. In addition, we report the results of analysis of 26 single nucleotide polymorphisms in six candidate genes examined for association to exercise adherence, duration, intensity and total exercise dose in young adults from the Training Interventions and Genetics of Exercise Response (TIGER) Study. Based on both animal and human research, neural signalling and pleasure/reward systems in the brain may drive in large part the propensity to be physically active and to adhere to an exercise programme. Adherence/compliance research in other fields may inform future investigation of the genetics of exercise adherence.

    2006-08-01

    A social ecological model provides a promising framework for understanding the individual, family, and societal factors contributing to non-adherence to treatment of paediatric HIV. This study explored which factors relevant to this model are associated with caregivers' adherence and child health outcomes. A cross-sectional design was utilized to assess relationships among current individual, familial, extra-familial factors, caregiver adherence, and viral load. Data were collected from 43 caregivers, and viral load data were obtained from the medical records of their HIV+ children. Caregiver drug and alcohol use and HIV+ status were associated with non-adherence and elevated viral load. Negative outcome expectancy was associated with lower adherence but was not significant in the multivariate analyses. Family factors were not significant, but these measures had low reliability in this sample. Extra-familial factors such as dissatisfaction with medical specialty care and more stressful life events were not directly associated with adherence but were related to increased caregiver substance use. Results of this first study to explore multiple predictors of adherence and health outcomes in paediatric HIV require replication with larger samples, but findings suggest caregiver characteristics that place children at risk for disease progression due to poor adherence to treatment.

    2014-06-01

    Full Text Available This study aimed to seek the evidence available in the literature regarding the factors related to adherence to treatment for systemic hypertension. It used the method of integrative review in the databases MEDLINE, CINAHL, and LILACS, using the keywords: hypertension, compliance, non-compliance, adherence, non-adherence, patient compliance, in the period 2004 – 2008, and articles in Portuguese, English and Spanish, with the use of a validated instrument and content analysis. 28 studies were selected, 64.3% of which had level of evidence VI. The following were identified as factors related to adherence to treatment: treatment costs, educational activities, sex, physician-patient relationship, physiological and behavioral aspects, drug therapy, attending checkups and lifestyle. The use of combined strategies is suggested in order to increase the individuals’ adherence to the treatment. Gaps point to the valorization of dialogic relationships for integrated and more efficacious health practices.

    Medication adherence and persistence is recognized as a worldwide public health problem, particularly important in the management of chronic diseases. Nonadherence to medical plans affects every level of the population, but particularly older adults due to the high number of coexisting diseases they are affected by and the consequent polypharmacy. Chronic disease management requires a continuous psychological adaptation and behavioral reorganization. In literature, many interventions to improve medication adherence have been described for different clinical conditions, however, most interventions seem to fail in their aims. Moreover, most interventions associated with adherence improvements are not associated with improvements in other outcomes. Indeed, in the last decades, the degree of nonadherence remained unchanged. In this work, we review the most frequent interventions employed to increase the degree of medication adherence, the measured outcomes, and the improvements achieved, as well as the main limitations of the available studies on adherence, with a particular focus on older persons.

  8. Quantification of the Forgiveness of Drugs to Imperfect Adherence.

    Assawasuwannakit, P; Braund, R; Duffull, S B

    2015-03-01

    The circumstance of how sensitive therapeutic success is under imperfect adherence is driven by the property known as forgiveness. To date, no studies have considered variability in the pharmacokinetic-pharmacodynamic process in conjunction with imperfect adherence patterns in order to develop a comparative criterion to determine the forgiveness of a drug. In this study, we have proposed a criterion to quantify forgiveness; illustrated the criterion for a theoretical example and evaluated the forgiveness of a motivating example, namely warfarin. A forgiveness criterion, relative forgiveness, is defined as the number of times more likely that a target is successfully attained under perfect adherence compared to imperfect adherence; or when comparing two drugs under a standard setting of imperfect adherence. The relative forgiveness criterion may have important implications for both drug development and clinical practice since the choice of drug can account for the likely influence of its forgiveness.

  9. Forgiveness of non-adherence to HIV-1 antiretroviral therapy.

    Shuter, Jonathan

    2008-04-01

    Superior adherence to HIV-1 antiretroviral therapy is a mainstay of successful HIV management. Studies performed in the early era of highly active antiretroviral therapy demonstrated the need for > or =95% adherence in order to achieve and sustain viral suppression. High rates of viral suppression have been observed at more moderate levels of adherence with newer antiretroviral regimens. The term 'forgiveness' is being used to describe the ability of a regimen to achieve and sustain viral suppression, despite suboptimal adherence. A variety of pharmacological, viral and host properties determine the level of forgiveness of any specific regimen. As the choice of treatment options continues to expand, forgiveness of non-adherence is likely to emerge as an increasingly important factor in therapeutic decision-making.

    It is widely recognized that adherence to antiretroviral therapy is critical to long-term treatment success, yet rates of adherence to antiretroviral medications are frequently subtherapeutic. Beliefs about antiretroviral therapy and psychosocial characteristics of HIV-positive persons naive to therapy may influence early experience with antiretroviral medication adherence and therefore could be important when designing programs to improve adherence to antiretroviral therapy. As part of a multicenter AIDS Clinical Trial Group (ACTG 384) study, 980 antiretroviral-naive subjects (82% male, 47% White, median age 36 years, and median CD4 cell count 278 cells/mm3) completed a self-administered questionnaire prior to random treatment assignment of initial antiretroviral medications. Measures of symptom distress, general health and well-being, and personal and situational factors including demographic characteristics, social support, self-efficacy, depression, stress, and current adherence to (nonantiretroviral) medications were recorded. Associations among variables were explored using correlation and regression analyses. Beliefs about the importance of antiretroviral adherence and ability to take antiretroviral medications as directed (adherence self-efficacy) were generally positive. Fifty-six percent of the participants were "extremely sure" of their ability to take all medications as directed and 48% were "extremely sure" that antiretroviral nonadherence would cause resistance, but only 37% were as sure that antiretroviral therapy would benefit their health. Less-positive beliefs about antiretroviral therapy adherence were associated with greater stress, depression, and symptom distress. More-positive beliefs about antiretroviral therapy adherence were associated with better scores on health perception, functional health, social-emotional-cognitive function, social support, role function, younger age, and higher education (r values = 0.09-0.24, all p < .001).

  15. Depression longitudinally mediates the association of appearance concerns to ART non-adherence in HIV-infected individuals with a history of injection drug use.

    Blashill, Aaron J; Gordon, Janna R; Safren, Steven A

    2014-02-01

    Appearance concerns are common among HIV-infected individuals, and previous cross-sectional and longitudinal data indicate that these concerns are associated with antiretroviral therapy (ART) non-adherence. However, to date, no known prospective data have explored the mechanism behind this relationship. Thus, the aim of the current study was to test depression severity as a prospective mediator of the relationship between appearance concerns and ART non-adherence in HIV-infected individuals with a history of injection drug use (IDU). Participants were 89 HIV-infected individuals with a history of IDU who participated in a prospective, randomized controlled trial of cognitive behavioral therapy for depression and medication adherence. Clinician-administered measures of depression severity and appearance concerns, along with electronic monitoring of ART non-adherence were included. Data were analyzed using longitudinal linear mixed-level modeling, and mediation was tested via the Monte Carlo Method of Assessing Mediation. Appearance concerns were predictive of depression severity, γ = .31, SE = .076, 95 % CI [.16, .46], t = 4.1, p = .0001, and depression severity was predictive of ART non-adherence, γ = 3.3, SE = 1.3, 95 % CI [.8, 5.8], t = 2.6, p = .01. The effect of appearance concerns on ART non-adherence, however, was significantly mediated by depression severity, γ = 1.02, 95 % CI [.21, 2.1]. Appearance concerns are associated with depression severity, which in turn is associated with ART non-adherence. Integrative interventions addressing appearance concerns, depression and ART adherence are needed, as this is one potential pathway towards worse health outcomes in HIV-infected individuals.

  16. Unravelling adherence to prophylaxis in haemophilia: a patients' perspective.

    Schrijvers, L H; Kars, M C; Beijlevelt-van der Zande, M; Peters, M; Schuurmans, M J; Fischer, K

    2015-09-01

    Given the lifelong therapy in haemophilia patients, insight in non-adherence behaviour from a patient perspective is important to understand patients' difficulties with the following treatment recommendations. The aim of this study was to clarify the process underlying adherence (behaviour) to prophylactic treatment, from a patients' perspective. To develop a grounded theory, a qualitative study using individual in-depth interviews was performed to understand experiences, perceptions and beliefs concerning adherence to prophylaxis. From two Dutch treatment centres, 21 adults with haemophilia using prophylaxis were interviewed. Patients were asked how they experience their task to administer prophylaxis and how they adhere to this. The interviews were transcribed, coded and analysed in an iterative process, leading to the development of the grounded theory. Adherence was determined by the position of prophylaxis in life. The position of prophylaxis was determined by the perception of prophylaxis and the ability to exert prophylaxis. Patients' perception was influenced by two main factors: acceptance of haemophilia and feeling/fearing symptoms. The ability to exert prophylaxis was influenced by understanding haemophilia and prophylaxis and planning/infusion skills. The combination of different perceptions and skills led to four main positions of prophylaxis in life: (i) prophylaxis integrated in life, (ii) prophylaxis according to doctors' advice, struggling with irregular situations, (iii) prophylaxis is too much to handle, (iv) prophylaxis is a confrontation with illness. The adherence level gradually decreased from position 1 to 4. This information can be used to design tailored interventions to promote adherence.

  17. Factors affecting adherence to a raw vegan diet.

    Link, Lilli B; Jacobson, Judith S

    2008-02-01

    The purpose of this study was to evaluate adherence and identify predictors of adherence to a raw vegan diet (i.e., uncooked plant foods) following a stay at a raw vegan institute. In this cohort study of guests at a raw vegan institute, subjects completed written questionnaires upon arrival and 12 weeks later. Of 107 eligible guests, 84 participated. Mean age was 54 years, 23 were male, and 73 white. Fifty-one completed the 12-week follow-up. Eight (16%) reported their diet to be 80% raw vegan at baseline and 14 (28%) at follow-up. Based on a raw vegan dietary adherence score (range 0-42) created for this study, mean adherence (SD) increased from 15.1 (5.4) to 17.0 (5.8) over 12 weeks (p=0.03). Baseline predictors of adherence included: education (beta=0.95), severity of disease (beta=0.98), and self-efficacy to adhere (beta=0.72). Future interventions that evaluate this diet should address self-efficacy, an important, potentially remediable predictor of adherence.

Adherence was measured as the medication possession ratio (MPR. Multivariate logistic regression compared treatment groups based on the likelihood of achieving ≥95% adherence, with sensitivity analyses using alternative thresholds. MPR was assessed as a continuous variable using multivariate linear regression. Covariates included age, gender, insurance payer type, year of study drug initiation, presence of mental health and substance abuse disorders, and third agent class. The study sample consisted of 650 FDC and 1947 NRTI Combo patients. Unadjusted mean adherence to the third agent was higher in the FDC group than the NRTI Combo group (0.92 vs 0.85; P < 0.0001. In regression analyses, FDC patients were 48% and 39% more likely to achieve 95% and 90% third agent adherence, respectively (P ≤ 0.03. None of the other MPR specifications achieved comparable results. Among managed care patients, use of an FDC appears to substantially improve adherence to a third regimen component and thus the likelihood of achieving the accepted standard for adherence to HIV therapy of 95%.Keywords

  19. Adherence to diabetes regimens: empirical status and clinical applications.

    Kurtz, S M

    1990-01-01

    Adherence to diabetes treatment regimens has proved to be a conceptual and empirical enigma. Consequently, reliable and valid applications to the clinical practice of diabetes care and education have been wanting. Rates of nonadherence are staggeringly high, regardless of the methodology employed, and verification of self-reports is complicated by social desirability to appear compliant. Low intertask correlations further complicate our understanding of adherence-metabolic control relationships. Studies relating to the Health Belief Model, social learning theory, and the psychology of interpersonal relationships that have sought to identify determinants of adherence behaviors have specific relevance to the clinical practice of diabetes education.

  1. Fewer Bacteria Adhere to Softer Hydrogels.

    Kolewe, Kristopher W; Peyton, Shelly R; Schiffman, Jessica D

    2015-09-01

    Clinically, biofilm-associated infections commonly form on intravascular catheters and other hydrogel surfaces. The overuse of antibiotics to treat these infections has led to the spread of antibiotic resistance and underscores the importance of developing alternative strategies that delay the onset of biofilm formation. Previously, it has been reported that during surface contact, bacteria can detect surfaces through subtle changes in the function of their motors. However, how the stiffness of a polymer hydrogel influences the initial attachment of bacteria is unknown. Systematically, we investigated poly(ethylene glycol) dimethacrylate (PEGDMA) and agar hydrogels that were 20 times thicker than the cumulative size of bacterial cell appendages, as a function of Young's moduli. Soft (44.05-308.5 kPa), intermediate (1495-2877 kPa), and stiff (5152-6489 kPa) hydrogels were synthesized. Escherichia coli and Staphylococcus aureus attachment onto the hydrogels was analyzed using confocal microscopy after 2 and 24 h incubation periods. Independent of hydrogel chemistry and incubation time, E. coli and S. aureus attachment correlated positively to increasing hydrogel stiffness. For example, after a 24 h incubation period, there were 52 and 82% fewer E. coli adhered to soft PEGDMA hydrogels than to the intermediate and stiff PEGDMA hydrogels, respectively. A 62 and 79% reduction in the area coverage by the Gram-positive microbe S. aureus occurred after 24 h incubation on the soft versus intermediate and stiff PEGDMA hydrogels. We suggest that hydrogel stiffness is an easily tunable variable that could potentially be used synergistically with traditional antimicrobial strategies to reduce early bacterial adhesion and therefore the occurrence of biofilm-associated infections.

  3. Dynamic logistic regression model and population attributable fraction to investigate the association between adherence, missed visits and mortality: a study of HIV-infected adults surviving the first year of ART

    2013-01-01

    Background Adherence is one of the most important determinants of viral suppression and drug resistance in HIV-infected people receiving antiretroviral therapy (ART). Methods We examined the association between long-term mortality and poor adherence to ART in DART trial participants in Uganda and Zimbabwe randomly assigned to receive laboratory and clinical monitoring (LCM), or clinically driven monitoring (CDM). Since over 50% of all deaths in the DART trial occurred during the first year on ART, we focussed on participants continuing ART for 12 months to investigate the implications of longer-term adherence to treatment on mortality. Participants’ ART adherence was assessed by pill counts and structured questionnaires at 4-weekly clinic visits. We studied the effect of recent adherence history on the risk of death at the individual level (odds ratios from dynamic logistic regression model), and on mortality at the population level (population attributable fraction based on this model). Analyses were conducted separately for both randomization groups, adjusted for relevant confounding factors. Adherence behaviour was also confounded by a partial factorial randomization comparing structured treatment interruptions (STI) with continuous ART (CT). Results In the CDM arm a significant association was found between poor adherence to ART in the previous 3-9 months with increased mortality risk. In the LCM arm the association was not significant. The odds ratios for mortality in participants with poor adherence against those with optimal adherence was 1.30 (95% CI 0.78,2.10) in the LCM arm and 2.18 (1.47,3.22) in the CDM arm. The estimated proportions of deaths that could have been avoided with optimal adherence (population attributable fraction) in the LCM and CDM groups during the 5 years follow-up period were 16.0% (95% CI 0.7%,31.6%) and 33.1% (20.5%,44.8%), correspondingly. Conclusions Recurrent poor adherence determined even through simple measures is associated

  4. Older Adults' Uptake and Adherence to Exercise Classes: Instructors' Perspectives.

    2016-01-01

    Exercise classes provide a range of benefits for older adults, but adherence levels are poor. We know little of instructors' experiences of delivering exercise classes to older adults. Semistructured interviews, informed by the Theory of Planned Behavior (TPB), were conducted with instructors (n = 19) delivering multicomponent exercise classes to establish their perspectives on older adults' uptake and adherence to exercise classes. Analysis revealed 'barriers' to uptake related to identity, choice/control, cost, and venue, and 'solutions' included providing choice/control, relating exercise to identity, a personal touch, and social support. Barriers to adherence included unrealistic expectations and social influences, and solutions identified were encouraging commitment, creating social cohesion, and an emphasis on achieving outcomes. Older adults' attitudes were an underlying theme, which related to all barriers and solutions. The instructor plays an important, but not isolated, role in older adults' uptake and adherence to classes. Instructors' perspectives help us to further understand how we can design successful exercise classes.

  5. Method of detaching adherent cells for flow cytometry

    Kaur, Mandeep

    2015-12-24

    In one aspect, a method for detaching adherent cells can include adding a cell lifting solution to the media including a sample of adherent cells and incubating the sample of adherent cells with the cell lifting solution. No scraping or pipetting is needed to facilitate cell detachment. The method do not require inactivation of cell lifting solution and no washing of detaching cells is required to remove cell lifting solution. Detached cells can be stained with dye in the presence of cell lifting solution and are further analyzed using flow cytometer. The method has been tested using 6 different cell lines, 4 different assays, two different plate formats (96 and 384 well plates) and two different flow cytometry instruments. The method is simple to perform, less time consuming, with no cell loss and makes high throughput flow cytometry on adherent cells a reality.

  6. In vitro adherence of Moraxella bovis to intact corneal epithelium.

    1984-09-01

    An in vitro assay is described using radiolabeled Moraxella bovis for studying adherence to intact bovine corneal epithelial surfaces. The assay was optimized for time (45 min) and for the ratio of epithelial cells to bacteria (1:1000) that demonstrated a significant difference in adherence between M. bovis strain 118F, a piliated organism and a nonpiliated variant, strain 118F/4-2. Adherence of these organisms correlated with previous pathogenicity studies involving experimental infection of calves. Scanning electron microscopy of tissues treated in the assay revealed a predilection of M. bovis for dark epithelial cells and for association with depressions in the tissue surface. This assay technique is discussed in comparison with other in vitro adherence assay methods.

  11. Engineering adherent bacteria by creating a single synthetic curli operon.

    Drogue, Benoît; Thomas, Philippe; Balvay, Laurent; Prigent-Combaret, Claire; Dorel, Corinne

    2012-11-16

    The method described here consists in redesigning E. coli adherence properties by assembling the minimum number of curli genes under the control of a strong and metal-overinducible promoter, and in visualizing and quantifying the resulting gain of bacterial adherence. This method applies appropriate engineering principles of abstraction and standardization of synthetic biology, and results in the BBa_K540000 Biobrick (Best new Biobrick device, engineered, iGEM 2011). The first step consists in the design of the synthetic operon devoted to curli overproduction in response to metal, and therefore in increasing the adherence abilities of the wild type strain. The original curli operon was modified in silico in order to optimize transcriptional and translational signals and escape the "natural" regulation of curli. This approach allowed to test with success our current understanding of curli production. Moreover, simplifying the curli regulation by switching the endogenous complex promoter (more than 10 transcriptional regulators identified) to a simple metal-regulated promoter makes adherence much easier to control. The second step includes qualitative and quantitative assessment of adherence abilities by implementation of simple methods. These methods are applicable to a large range of adherent bacteria regardless of biological structures involved in biofilm formation. Adherence test in 24-well polystyrene plates provides a quick preliminary visualization of the bacterial biofilm after crystal violet staining. This qualitative test can be sharpened by the quantification of the percentage of adherence. Such a method is very simple but more accurate than only crystal violet staining as described previously with both a good repeatability and reproducibility. Visualization of GFP-tagged bacteria on glass slides by fluorescence or laser confocal microscopy allows to strengthen the results obtained with the 24-well plate test by direct observation of the phenomenon.

  12. Medication adherence: the critical step towards better patient outcome

    Anish Desai

    2014-10-01

    Full Text Available Medication adherence is defined as patient's adherence to take their medications as prescribed and continue to take the prescribed medication for stipulated time frame. Medication non-adherence is a growing concern to physicians, healthcare systems, and other stakeholders (e.g., payers and there is an increasing evidence of its prevalence and is associated with adverse clinical outcomes eventually resulting into higher costs of care. The cost of non-adherence has been estimated at $100 billion to $300 billion annually, including costs from avoidable hospitalizations, nursing home admissions, and premature deaths. Improving adherence to medication is critical to improve the quality of health care, to encourage better chronic care management, and promote better health outcomes. Reasons for non-adherence are multiple and complex. Studies have reported that poor adherence to drug dosage is due to patient perception that the disease is non-significant, adverse drug effects, lack of treatment effectiveness, and the patient's poor or incomplete knowledge of the disease and (cost. A multifactorial approach is required to tackle this complex problem as a single approach will be ineffective for all patients. The most effective intervention is to use a combination of approaches and address literacy, behavior, and organizational issues. There are challenges as well as opportunities in addressing the public health issue of medication adherence. Changing healthcare reforms, advances in digital health media, social media and modern technologies can now provide alternatives to tackle this issue.

This review addresses current knowledge on medication-taking behavior in people with epilepsy, as well as the importance of tailoring interventions to the individual patterns of non-adherence. Non-adherence can be categorized as non-initiation, poor execution (accidental or intentional) or non-persistence and are related to clinical characteristics and health care barriers. All available methods to assess adherence are hampered by shortcomings. Self-reports are indirect and subjective. Pill-counts, electronic bottle-tops and pharmacy records are objective, but indirect measures of drug ingestion. Therapeutic drug monitoring is both direct and objective, but pharmacokinetic and diurnal variability must be taken into account. Young adults with generalized epilepsy may be particularly vulnerable to non-adherence. The drug burden in the form of polytherapy, multiple dosing and side effects are obvious obstacles. Poor understanding of the principles of prophylactic treatment as well as drug costs may be important in people with low socioeconomic status. Depression is also associated with low adherence. In people with multihandicaps, failed oral intake may be due to behavioral or physical problems, as well as insufficient education of the caregivers. Non-adherence often results in seizure breakthrough and hospital admissions, but the consequences may be more dramatic. It is the leading cause of status epilepticus in people with epilepsy, and the association with sudden death (SUDEP) is clear. The management of poor drug-taking behavior should be based on the identification of the specific causes in each individual and corresponding multiprofessional interventions. Non-adherence to antiepileptic drugs needs more clinical and scientific attention.

    Full Text Available This paper explores the monetary expectations induced to the managers of Romanian firms by adheration. It is based on an investigation among twenty Romanian executives regarding the impact on adheration over monetary aspects: inflation, exchange rates and adoption of euro. We conclude that the results of the monetary policy in the last years made the executives confident that the Romanian authorities could maintain the monetary stability after theadheration.

    The aim of the present study was to evaluate the psychometric properties of the Competence and Adherence Scale for Cognitive Behavioral Therapy (CAS-CBT). The CAS-CBT is an 11-item scale developed to measure adherence and competence in cognitive-behavioral therapy (CBT) for anxiety disorders in youth. A total of 181 videotapes from the treatment sessions in a randomized controlled effectiveness trial (Wergeland et al., 2014) comprising youth (N = 182, M age = 11.5 years, SD = 2.1, range 8-15 years, 53% girls, 90.7% Caucasian) with mixed anxiety disorders were assessed with the CAS-CBT to investigate interitem correlations, internal consistency, and factor structure. Internal consistency was good (Cronbach's alpha = .87). Factor analysis suggested a 2-factor solution with Factor 1 representing CBT structure and session goals (explaining 46.9% of the variance) and Factor 2 representing process and relational skills (explaining 19.7% of the variance). The sum-score for adherence and competence was strongly intercorrelated, r = .79, p .40, n = 10 videotapes) and also good to excellent interrater reliability when compared to expert raters (ICC = .83 for adherence and .64 for competence, n = 26 videotapes). High rater stability was also found (n = 15 videotapes). The findings suggest that the CAS-CBT is a reliable measure of adherence and competence in manualized CBT for anxiety disorders in youth. Further research is needed to investigate the validity of the scale and psychometric properties when used with other treatment programs, disorders and treatment formats. (PsycINFO Database Record

  17. Common mental health problems and antiretroviral therapy adherence.

    Nel, Adriaan; Kagee, Ashraf

    2011-11-01

    This paper reviews the literature on various mental health problems and their impact on adherence to antiretroviral therapy (ART). Depression, anxiety disorders, and disorders related to substance abuse were identified as key role-players influencing adherence. The severity of symptoms related to these disorders was found to be inversely related to ART adherence, with the possible exception of post-traumatic stress disorder (PTSD). PTSD was found to have both positive and negative implications for adherence, with severity of symptoms ranging from health-protective concern to disabling distress. Possible solutions aimed at addressing the adverse effects of mental health problems on adherence are discussed. Routine screening in ART settings is suggested in settings where follow-up of positive screen scores are possible, along with the necessary interventions to resolve the disorder of concern. Suggested interventions include utilising psychotherapeutic treatment, both in isolation and in conjunction with medication, to address mental health problems. Furthermore, finding effective ways of marshalling social support is recommended for ensuring optimal adherence, and possibly mitigating the adverse effects of mental health problems. Further research is needed to find feasible ways of identifying, assessing and treating patients with mental health problems in resource-constrained settings where HIV prevalence is highest.

    Using a pilot trial design in an HIV care clinic in Zimbabwe, we randomised 32 adults with poor adherence to antiretroviral therapy and at least mild depression to either six sessions of Problem-Solving Therapy for adherence and depression (PST-AD) delivered by an adherence counsellor, or to Enhanced Usual Care (Control). Acceptability of PST-AD was high, as indicated by frequency of session attendance and through qualitative analyses of exit interviews. Fidelity was >80% for the first two sessions of PST-AD but fidelity to the adherence component of PST-AD dropped by session 4. Contamination occurred, in that seven patients in the control arm received one or two PST-AD sessions before follow-up assessment. Routine health records proved unreliable for measuring HIV viral load at follow-up. Barriers to measuring adherence electronically included device failure and participant perception of being helped by the research device. The study was not powered to detect clinical differences, however, promising change at 6-months follow-up was seen in electronic adherence, viral load suppression (PST-AD arm 9/12 suppressed; control arm 4/8 suppressed) and depression (Patient Health Questionnaire-4.7 points in PST-AD arm vs. control, adjusted p value = 0.01). Results inform and justify a future randomised controlled trial of task-shifted PST-AD.

  19. Adherence to Internet-based and face-to-face cognitive behavioural therapy for depression: a meta-analysis.

    Wouter van Ballegooijen

    Full Text Available BACKGROUND: Internet-based cognitive behavioural therapy (iCBT is an effective and acceptable treatment for depression, especially when it includes guidance, but its treatment adherence has not yet been systematically studied. We conducted a meta-analysis, comparing the adherence to guided iCBT with the adherence to individual face-to-face CBT. METHODS: Studies were selected from a database of trials that investigate treatment for adult depression (see www.evidencebasedpsychotherapies.org, updated to January 2013. We identified 24 studies describing 26 treatment conditions (14 face-to-face CBT, 12 guided iCBT, by means of these inclusion criteria: targeting depressed adults, no comorbid somatic disorder or substance abuse, community recruitment, published in the year 2000 or later. The main outcome measure was the percentage of completed sessions. We also coded the percentage of treatment completers (separately coding for 100% or at least 80% of treatment completed. RESULTS: We did not find studies that compared guided iCBT and face-to-face CBT in a single trial that met our inclusion criteria. Face-to-face CBT treatments ranged from 12 to 28 sessions, guided iCBT interventions consisted of 5 to 9 sessions. Participants in face-to-face CBT completed on average 83.9% of their treatment, which did not differ significantly from participants in guided iCBT (80.8%, P  =  .59. The percentage of completers (total intervention was significantly higher in face-to-face CBT (84.7% than in guided iCBT (65.1%, P < .001, as was the percentage of completers of 80% or more of the intervention (face-to-face CBT: 85.2%, guided iCBT: 67.5%, P  =  .003. Non-completers of face-to-face CBT completed on average 24.5% of their treatment, while non-completers of guided iCBT completed on average 42.1% of their treatment. CONCLUSION: We did not find studies that compared guided iCBT and face-to-face CBT in a single trial. Adherence to guided iCBT appears to be

    Full Text Available Andrea Tumminia,1 Laura Sciacca,1 Lucia Frittitta,1 Sebastiano Squatrito,1 Riccardo Vigneri,2 Rosario Le Moli,1 Letizia Tomaselli2 1Endocrinology, Department of Clinical and Experimental Medicine, University of Catania, Garibaldi-Nesima Hospital, Catania, Italy; 2Endocrinology, Garibaldi-Nesima Hospital, Catania, Italy Abstract: Insulin pump therapy combined with real-time continuous glucose monitoring, known as sensor-augmented pump (SAP therapy, has been shown to improve metabolic control and to reduce the rate of hypoglycemia in adults with type 1 diabetes compared to multiple daily injections or standard continuous subcutaneous insulin infusion. Glycemic variability is also reduced in patients on SAP therapy. This approach allows patients to monitor their glucose levels being informed of glycemic concentration and trend. Trained diabetic patients, therefore, can appropriately modify insulin infusion and/or carbohydrate intake in order to prevent hypo- or hyperglycemia. For these reasons, SAP therapy is now considered the gold standard for type 1 diabetes treatment. To be clinically effective, however, devices and techniques using advanced technology should not only have the potential to theoretically ameliorate metabolic control, but also be well accepted by patients in terms of satisfaction and health-related quality of life, because these factors will improve treatment adherence and consequently overall outcome. SAP therapy is generally well tolerated by patients; however, many clinical trials have identified significant noncompliance in the use of this device, most notably in the pediatric and adolescent populations. In this review we aim to analyze the main reasons for good or poor adherence to SAP therapy and to provide useful tips in order to fully benefit from this kind of novel therapeutic approach.

The objectives of this study were to assess the adherence level to antihypertensive treatment and to identify its associated factors in a sample of hypertensive patients in Lebanon and Jordan. Methods: We conducted an observational study between May 2011 and September 2012. A total of 1,470 eligible hypertensive patients were enrolled in our study and followed up for a period of 6 months. Data were collected regarding sociodemographic, health behavior, and hypertension-related characteristics. The adherence to treatment and the quality of life were self-reported using the Morisky, Green & Levine Scale and the Hypertension Quality of Life Questionnaire. Results: Our results revealed that 55.9 % of the patients were adherent to their antihypertensive medication. Older age was associated with better adherence, whereas being divorced or widowed, having a poorer quality of life, and being classified as having stage 1 or 2 hypertension at the end of the study were all associated with poorer adherence. Conclusion: Efforts should be exerted on all levels in order to increase the adherence to antihypertensive treatment through the implementation of educational campaigns.

  5. [Atrial fibrillation and adherence to guidelines in the real world: myth or reality?].

    Meiltz, A; Zimmermann, M

    2009-03-04

    Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia with a prevalence increasing with the aging of the population. AF has become a public health problem in general clinical practice. Despite the conclusive evidence of numerous randomized trials and publication of unified guidelines, their application in the real-world is often sub-optimal, in particular concerning the anticoagulation prescription. Most of these reports have focused on hospitalized patients or were performed by generalists, whereas in the real-world AF is managed in an out-of-hospital setting with growing implication of cardiologists. The purpose of this presentation is to demonstrate that a strict adherence to international guidelines can be obtained in the real-world of AF management. However, some improvements are needed to get an optimal use of anticoagulation.

  6. A Comparison of the impact of family-centered and patient-centered education methods on attitude toward and adherence to diet and fluid restriction in hemodialysis patients

    Full Text Available Background and Objective: One of the major issues in hemodialysis patients is adherence to diet and fluid restriction. In order to reduce the adverse consequences of the disease and improve quality of life, educating these patients is of great importance. Therefore, the present study was conducted in order to compare the impact of two methods of education (patient-centered and family–centered on attitude toward and adherence to diet and fluid restriction in hemodialysis patients. Materials and Method: This clinical trial was performed on patients referred to the hemodialysis ward of hospitals affiliated with Tehran University of Medical Sciences, Iran, during May to October 2012. Through purposive sampling method, 60 patients were selected and randomly assigned to two groups patient-centered (n = 30 and family-centered (n = 30. Patients’ attitude toward and adherence to diet regime and fluid restriction were assessed using a researcher-made self-report questionnaire in 3 stages (before the intervention, and 2 and 4 weeks after the intervention. The reliability and validity of the questionnaire were approved. Data analysis was performed using SPSS software version 16 and independent t-test, chi-square, Fisher’s exact test, and repeated measures ANOVA. Results: Before the intervention, the findings showed no significant difference between the 2 groups in terms of adherence to diet and fluid restriction. In the second week after the intervention, mean adherence to diet in the family-centered group was significantly higher than the patient-centered group (P = 0.010. Moreover, at the end of the second (P = 0.001 and fourth weeks (P = 0.002, the attitude toward adherence to diet and fluid restriction was more positive in the family-centered group, in comparison to the patient-centered group. Conclusion: Family-centered education is more effective on patient adherence to the treatment regimen. Thus, it is recommended that family

    Objectives The effectiveness of community level interventions depends to a great extent on adherence. Currently, information on factors related to adherence in older adults from developing countries is scarce. Our aim was to identify factors associated to adherence to a physical activity intervention in older adults from a post-transitional middle income country. Design, setting and participants Using a combination of quantitative and qualitative methods we studied 996 older Chilean subjects (65-67.9 years at baseline) with low to medium socioeconomic status from 10 health centers randomized to receive a physical activity intervention as part of the CENEX cluster trial (ISRCTN48153354). Measurements Using a multilevel regression model, the relationship between adherence (defined a priori as attendance at a minimum of 24 physical activity classes spread over at least 12 months) and individual, intervention-related and contextual factors was evaluated. We also conducted 40 semi-structured interviews with older adults (n=36) and instructors (n=4). Transcripts of the interviews were analyzed using content analysis to identify barriers and facilitators to adherence. Results Adherence to physical activity intervention was 42.6% (CI 95% 39.5 to 45.6). Depression, diabetes mellitus, percentage of impoverished households and rate of arrests for violent crimes in the neighborhood predicted less adherence (pbenefits attributed to the intervention and the opportunity the classes provided for social interaction with others. Conclusion In order to enhance effectiveness of community exercise interventions, strategies to improve participation should be targeted to older adults from deprived areas and those with psychological and medical conditions.

    2015-08-01

    It is believed that patients' expectancies about the effectiveness of treatment influence their treatment outcomes, but the working mechanism is rarely studied in patients with low back pain. Theoretical models suggest that adherence to treatment may be an important pathway. The aim of this study was to assess the mediating role of adherence to treatment in the relationship between expectancies and the outcomes of recovery and pain intensity in patients with acute low back pain. This study used data from a randomized placebo-controlled trial of paracetamol for acute low back pain. Expectancies were measured with the Credibility Expectancy Questionnaire. Adherence was measured with a medication diary. Pain intensity was recorded daily in a diary on a 0 to 10 pain scale, and recovery was defined as the first of 7 consecutive days scoring 0 or 1 on a 6-point pain scale. Cox regression (dependent variable: recovery) and linear mixed-model analyses (dependent variable: daily pain intensity scores) were performed. The "difference in coefficients" approach was used to establish mediation. A total of 1573 participants were included in current analyses. There was a small but highly significant relationship between expectancies and outcomes; 3.3% of the relationship between expectancies and recovery and 14.2% of the relationship between expectancies and pain intensity were mediated by adherence to treatment. This study does not convincingly support the theory that adherence is a key pathway in the relationship between treatment outcome expectancies and recovery and pain intensity in this acute low back pain population.

    The purpose of this study was to test an intervention to increase mammography screening in women 51-75 years of age who had not received a mammogram in the last 15 months. A total of 1681 women were randomized to (1) a mailed tailored interactive DVD, (2) a computer-tailored telephone counseling, or (3) usual care. Women with income below US$75,000 who were in the interactive DVD group had significantly more mammograms than women in usual care. Women with income above US$75,000 had significantly fewer mammograms than women with income less than US$75,000 regardless of group. Further investigation is needed to understand why women with income above US$75,000 did not show the same benefit of the intervention.

  16. Impact of an exercise program on adherence and fitness indicators.

    Carpenter, Roger; Gilleland, Diana

    2016-05-01

    Adherence to exercise is one of the most problematic health behaviors. This pilot study describes the impact of an exercise program on adherence to exercise and fitness indicators for overweight and obese adults enrolled in an insurance reimbursed exercise plan. Chart reviews were conducted retrospectively in a convenience sample of 77 subjects from a human performance lab (HPL) at a large southern university. Charts from 2004 to 2009 were reviewed for health history, fitness indicators (fitness level, weight, BMI, hip/waist ratio, % body fat, BP, HR, cholesterol), and adherence (number of exercise sessions/month). Exercise supervision was operationalized in two phases over 12 months: Phase I (3 months supervised exercise) and Phase II (9 months unsupervised exercise). Fifty-eight participants completed Phase I, and 8 completed Phase II. Six-nine percent of those completing Phase I visited the gym at least 8 times/month with significant (α=.05) improvement in all fitness indicators. Those visiting body fat. Twenty-four subjects continued into Phase II, with only eight completing Phase II. Of those eight, only one subject visited the HPL at least 8 times/month. Health history data including co-morbidities, symptoms, habits, perceived tension, job stress, and fitness level were not associated with adherence. Symptoms of swollen, stiff, painful joints, and swollen ankles and legs were associated with decreased adherence to exercise. Supervised exercise was positively related to adherence and improved fitness indicators. Adults with joint symptoms may require more support. Based on these pilot data, designing a study with a larger sample and the inclusion of barriers and facilitators for adherence to self-directed exercise would allow additional analysis. Innovative interventions are needed that mimic the supervised environment, shifting responsibility for the exercise plan from the supervisor to those exercising.

  17. Perceived barriers to guideline adherence: A survey among general practitioners

    Besters Casper F

    2011-09-01

    Full Text Available Abstract Background Despite considerable efforts to promote and support guideline use, adherence is often suboptimal. Barriers to adherence vary not only across guidelines but also across recommendations within guidelines. The aim of this study was to assess the perceived barriers to guideline adherence among GPs by focusing on key recommendations within guidelines. Methods We conducted a cross-sectional electronic survey among 703 GPs in the Netherlands. Sixteen key recommendations were derived from four national guidelines. Six statements were included to address the attitudes towards guidelines in general. In addition, GPs were asked to rate their perceived adherence (one statement and the perceived barriers (fourteen statements for each of the key recommendations, based on an existing framework. Results 264 GPs (38% completed the questionnaire. Although 35% of the GPs reported difficulties in changing routines and habits to follow guidelines, 89% believed that following guidelines leads to improved patient care. Perceived adherence varied between 52 and 95% across recommendations (mean: 77%. The most perceived barriers were related to external factors, in particular patient ability and behaviour (mean: 30% and patient preferences (mean: 23%. Lack of applicability of recommendations in general (mean: 22% and more specifically to individual patients (mean: 25% were also frequently perceived as barriers. The scores on perceived barriers differed largely between recommendations [minimum range 14%; maximum range 67%]. Conclusions Dutch GPs have a positive attitude towards the NHG guidelines, report high adherence rates and low levels of perceived barriers. However, the perceived adherence and perceived barriers varied largely across recommendations. The most perceived barriers across recommendations are patient related, suggesting that current guidelines do not always adequately incorporate patient preferences, needs and abilities. It may be

    2010-06-01

    The aim of the present work was to assess the prevalence of the Mediterranean dietary pattern (MDP) in Balearic Islands adolescents, and socio-demographic and lifestyle factors that might determine adherence to the MDP. A cross-sectional nutritional survey was carried out in the Balearic Islands between 2007 and 2008. A random sample (n 1231) of the adolescent population (12-17 years old) was interviewed. Dietary questionnaires and a general questionnaire incorporating questions related to socio-economic status, parental education level and lifestyle factors were used. Dietary habits were assessed by means of two 24 h recalls and a quantitative FFQ. Adherence to the MDP was defined according to a score constructed considering the consumption of nine MDP characteristic components: high MUFA:SFA ratio, moderate ethanol consumption, high legumes, cereals and roots, fruits, vegetables and fish consumption, and low consumption of meat and milk. Then, socio-demographic, lifestyle and health status variables that could determine a higher or ower adherence were assessed. The mean adherence was 57.9 (sd 8.9) % and the median adherence was 57.3 %. Half of the Balearic Islands adolescents (50.5 %) showed an adherence to the MDP comprised between 52.7 and 62.8 %. By multivariate analyses, a high maternal level of education, increased physical activity, reduced alcohol intake and abstinence from smoking were independent associations of better adherence to the MDP. The promotion of not only the MDP but also the Mediterranean lifestyle, including greater physical activity, should be reinforced among the Balearic younger generations.

A central issue is the need to protect patient privacy and adhere to Good Clinical and Statistical Practices, while ensuring access to patient-level data from clinical trials to the wider research community. This paper offers options to navigate this dilemma and balance competing priorities, with emphasis on the role of good clinical and statistical practices as proven safeguards for scientific integrity, the importance of adopting best practices for reporting of data from secondary analyses, and the need for optimal collaboration among stakeholders to facilitate data sharing.

    Full Text Available Introduction: Adherence to antiretroviral therapy (ART plays an important role in treatment outcomes. It is crucial to identify factors influencing adherence in order to optimize treatment responses. The aim of this study was to assess the rates of, and factors associated with, suboptimal adherence (SubAdh in the first 24 months of ART in an Asian HIV cohort. Methods: As part of a prospective resistance monitoring study, the TREAT Asia Studies to Evaluate Resistance Monitoring Study (TASER-M collected patients’ adherence based on the World Health Organization-validated Adherence Visual Analogue Scale. SubAdh was defined in two ways: (i 14 days. Time was divided into four intervals: 0–6, 6–12, 12–18 and 18–24 months. Factors associated with SubAdh were analysed using generalized estimating equations. Results: Out of 1316 patients, 32% ever reported 2 assessments per patient per year had an odds ratio (OR=0.7 (95% confidence interval (CI (0.55 to 0.90, p=0.006, compared to sites with ≤2 assessments per patient per year. Compared to heterosexual exposure, SubAdh was higher in injecting drug users (IDUs (OR=1.92, 95% CI (1.23 to 3.00, p=0.004 and lower in homosexual exposure (OR=0.52, 95% CI (0.38 to 0.71, p<0.001. Patients taking a nucleoside transcriptase inhibitor and protease inhibitor (NRTI+PI combination were less likely to report adherence <100% (OR=0.36, 95% CI (0.20 to 0.67, p=0.001 compared to patients taking an NRTI and non-nucleoside transcriptase inhibitor (NRTI+NNRTI combination. SubAdh decreased with increasing time on ART (all p<0.001. Similar associations were found with adherence <95% as the outcome. Conclusions: We found that SubAdh, defined as either <100% and <95%, was associated with mode of HIV exposure, ART regimen, time on ART and frequency of adherence measurement. The more frequently sites assessed patients, the lower the SubAdh, possibly reflecting site resourcing for patient counselling. Although social

    Full Text Available Kimberly M Shuler Shuler Counseling and Consulting, Fayetteville, AR, USA Purpose: In patients with schizophrenia, nonadherence to prescribed medications increases the risk of patient relapse and hospitalization, key contributors to the costs associated with treatment. The objectives of this review were to evaluate the impact of nonadherence to pharmacotherapy in patients with schizophrenia as it relates to health care professionals, particularly social workers, and to identify effective team approaches to supporting patients based on studies assessing implementation of assertive community treatment teams. Materials and methods: A systematic review of the medical literature was conducted by searching the Scopus database to identify articles associated with treatment adherence in patients with schizophrenia. Articles included were published from January 1, 2003, through July 15, 2013, were written in English, and reported findings concerning any and all aspects of nonadherence to prescribed treatment in patients with schizophrenia. Results: Of 92 unique articles identified and formally screened, 47 met the inclusion criteria for the systematic review. The burden of nonadherence in schizophrenia is significant. Factors with the potential to affect adherence include antipsychotic drug class and formulation, patient-specific factors, and family/social support system. There is inconclusive evidence suggesting superior adherence with an atypical versus typical antipsychotic or with a long-acting injectable versus an oral formulation. Patient-specific factors that contribute to adherence include awareness/denial of illness, cognitive issues, stigma associated with taking medication, substance abuse, access to health care, employment/poverty, and insurance status. Lack of social or family support may adversely affect adherence, necessitating the assistance of health care professionals, such as social workers. Evidence supports the concept that an

    Adherence to antiretroviral therapy (ART) is an important determinant of clinical success assessed in many HIV studies. Harmonizing adherence data from studies that use different measures is difficult without a co-calibration equation to convert between validated instruments. Our purpose was to co-calibrate two commonly used adherence measures: the AIDS Clinical Trials Group (ACTG) questionnaire and the Visual Analog Scale (VAS). We used robust linear regression to develop a co-calibration equation in a clinical care cohort. The outcome was the 30-day VAS percentage of ART taken and the predictors were ACTG questions. We evaluated the equation's goodness of fit in five STTR (Seek, Test, Treat, Retain) consortium studies where individuals completed both measures: 2 criminal justice; 2 international; and 1 other high-risk vulnerable population. We developed a three-phase decision rule to convert ACTG to VAS in 1045 participants. First, when the last missed dose on the ACTG was reported as >30 days ago, the VAS was set to 100% (N = 582). Second, if "doses missed" was zero for all items, VAS was 100% (N = 104). Third, among remaining participants (N = 359), VAS was estimated as 96.8% minus 2.9% times the number of missed doses ("doses per day" was non-significant). Correlation between predicted and reported VAS was r = 0.80 in the criminal justice group (N = 446), r = 0.46 in the international group (N = 311), r = 0.32 in the other vulnerable population (N = 63), and r = 0.66 overall. When outliers due to inversion of the VAS scale were excluded (n = 25), these correlations were 0.88, 0.78, 0.80, and 0.86, respectively. We concluded that a simple decision rule and equation allowed us to co-calibrate between two widely used adherence measures thus combining data from studies with different instruments. This study highlighted issues with VAS inversions and its limitations as a single item. Combining studies using different

    Full Text Available BACKGROUND: Combination antiretroviral treatment (cART has been very successful, especially among selected patients in clinical trials. The aim of this study was to describe outcomes of cART on the population level in a large national cohort. METHODS: Characteristics of participants of the Swiss HIV Cohort Study on stable cART at two semiannual visits in 2007 were analyzed with respect to era of treatment initiation, number of previous virologically failed regimens and self reported adherence. Starting ART in the mono/dual era before HIV-1 RNA assays became available was counted as one failed regimen. Logistic regression was used to identify risk factors for virological failure between the two consecutive visits. RESULTS: Of 4541 patients 31.2% and 68.8% had initiated therapy in the mono/dual and cART era, respectively, and been on treatment for a median of 11.7 vs. 5.7 years. At visit 1 in 2007, the mean number of previous failed regimens was 3.2 vs. 0.5 and the viral load was undetectable (4 previous failures compared to 1 were 0.9 (95% CI 0.4-1.7, 0.8 (0.4-1.6, 1.6 (0.8-3.2, 3.3 (1.7-6.6 respectively, and 2.3 (1.1-4.8 for >2 missed cART doses during the last month, compared to perfect adherence. From the cART era, odds ratios with a history of 1, 2 and >2 previous failures compared to none were 1.8 (95% CI 1.3-2.5, 2.8 (1.7-4.5 and 7.8 (4.5-13.5, respectively, and 2.8 (1.6-4.8 for >2 missed cART doses during the last month, compared to perfect adherence. CONCLUSIONS: A higher number of previous virologically failed regimens, and imperfect adherence to therapy were independent predictors of imminent virological failure.

    Full Text Available Abstract Background Trial-based thought record (TBTR is a technique used in trial-based cognitive therapy (TBCT, and simulates a court trial. It was designed to restructure unhelpful core beliefs (CBs during psychotherapy. Objective To confirm previous findings on the efficacy of TBTR in decreasing patients’ adherence to self-critical and unhelpful CBs and corresponding emotions, as well as assessing the differential efficacy of the empty-chair approach relative to the static format of TBTR. Methods Thirty-nine outpatients were submitted to a 50-minute, one-session, application of the TBTR technique in the empty-chair (n = 18 or conventional (n = 21 formats. Patients’ adherence to unhelpful CBs and the intensity of corresponding emotions were assessed after each step of TBTR, and the results obtained in each format were compared. Results Significant reductions in percent values both in the credit given to CBs and in the intensity of corresponding emotions were observed at the end of the session (p < .001, relative to baseline values. ANCOVA also showed a significant difference in favor of the empty-chair format for both belief credit and emotion intensity (p = .04. Discussion TBTR may help patients reduce adherence to unhelpful CBs and corresponding emotions and the empty-chair format seems to be more efficacious than the conventional format.

    Full Text Available Abstract Background Adherence with tobramycin inhalation solution (TIS during routine cystic fibrosis (CF care may differ from recommended guidelines and affect health care utilization. Methods We analyzed 2001-2006 healthcare claims data from 45 large employers. Study subjects had diagnoses of CF and at least 1 prescription for TIS. We measured adherence as the number of TIS therapy cycles completed during the year and categorized overall adherence as: low ≤ 2 cycles, medium >2 to Results Among 804 individuals identified with CF and a prescription for TIS, only 7% (n = 54 received ≥ 4 cycles of TIS per year. High adherence with TIS was associated with a decreased risk of hospitalization when compared to individuals receiving ≤ 2 cycles (adjusted odds ratio 0.40; 95% confidence interval 0.19-0.84. High adherence with TIS was also associated with lower outpatient service costs (IQR: $2,159-$8444 vs. $2,410-$14,423 and higher outpatient prescription drug costs (IQR: $35,125-$60,969 vs. $10,353-$46,768. Conclusions Use of TIS did not reflect recommended guidelines and may impact other health care utilization.

    Full Text Available Purpose. We hypothesized that socioeconomic factors and a language barrier would impact adherence with continuous positive airway pressure (CPAP among Hispanics with obstructive sleep apnea (OSA. Methods. Patients with OSA who were prescribed CPAP for at least 1 year and completed a questionnaire evaluating demographic data, socioeconomic status, and CPAP knowledge and adherence participated in the study. Results. Seventy-nine patients (26 males; 53±11 yrs; body mass index (BMI=45±9 kg/m2 with apnea-hypopnea index (AHI 33±30 events/hr completed the study. Included were 25 Hispanics, 39 African Americans, and 15 Caucasians, with no difference in age, AHI, CPAP use, or BMI between the groups. While there was a difference in educational level (P=0.006, income level (P<0.001, and employment status (P=0.03 between the groups, these did not influence CPAP adherence. Instead, overall improvement in quality of life and health status and perceived benefit from CPAP influenced adherence, both for the group as a whole (P=0.03, P=0.004, and P=0.001, resp., as well as in Hispanics (P=0.02, P=0.02, P=0.03, resp.. Conclusion. In Hispanic patients with OSA, perceived benefit with therapy, rather than socioeconomic status or a language barrier, appears to be the most important factor in determining CPAP adherence.

    The bacterial adherence onto different multifunctional silica-based bioceramics has been evaluated. Staphylococcus aureus and Staphylococcus epidermidis were chosen, as they cause the majority of the implant-related infections in this field. Two SiO2 mesoporous materials (MCM-41, SBA-15), an ordered SiO2-CaO-P2O5 mesoporous glass (OMG), and a biphasic magnetic bioceramic (BMB), were incubated with S. aureus and S. epidermidis for 90 min, and subsequently sonicated to quantify the number of adhered bacteria on each material. It was found that S. aureus and S. epidermidis (10(8) CFU/mL) adhered significantly less to BMB samples when compared to MCM-41, SBA-15, or OMG. However, when the material pores accessible for bacteria in each material were taken into account, the lowest bacterial adherence was found in MCM-41, and the highest in SBA-15. The results show that bacterial adherence is higher on mesoporous bioceramics, although this higher microbial attachment is mainly due to the intergranular porosity and grain size morphology rather than to the mesoporous structure.

  9. Improving patient outcomes in psoriasis: strategies to ensure treatment adherence

    Full Text Available Oriol Yélamos, Sandra Ros, Lluís Puig Department of Dermatology, Hospital de la Santa Creu i Sant Pau – Universitat Autònoma de Barcelona, Barcelona, Catalonia, Spain Abstract: Psoriasis is a frequent inflammatory disease with a chronic and relapsing course. Therefore, patients with psoriasis are likely to undergo different treatments for long periods of time. Traditionally, therapies used in psoriasis have been associated with poor levels of adherence due to the complexity of the regimens and the poor results obtained with the topical therapies. These poor outcomes are associated with high levels of frustration and anxiety, which decrease adherence and worsen the disease. With the recent introduction of highly efficacious biologic therapies, patients can achieve very good and prolonged responses. However, most patients with psoriasis have mild disease and may be treated with skin-directed therapies. Therefore, it is important to develop strategies to improve adherence in order to achieve better outcomes, and to improve the overall quality of life. Hence, acknowledging the causes of nonadherence is crucial for implementing these strategies. In this summary, we review the causes of nonadherence, and we provide behavioral strategies in order to improve adherence and, ultimately, the outcome of patients with psoriasis.

  10. The therapeutic relationship and adherence to antipsychotic medication in schizophrenia.

    Rosemarie McCabe

    Full Text Available OBJECTIVE: Previous research has shown that a better therapeutic relationship (TR predicts more positive attitudes towards antipsychotic medication, but did not address whether it is also linked with actual adherence. This study investigated whether the TR is associated with adherence to antipsychotics in patients with schizophrenia. METHODS: 134 clinicians and 507 of their patients with schizophrenia or a related psychotic disorder participated in a European multi-centre study. A logistic regression model examined how the TR as rated by patients and by clinicians is associated with medication adherence, adjusting for clinician clustering and symptom severity. RESULTS: Patient and clinician ratings of the TR were weakly inter-correlated (r(s = 0.13, p = 0.004, but each was independently linked with better adherence. After adjusting for patient rated TR and symptom severity, each unit increase in clinician rated TR was associated with an increase of the odds ratio of good compliance by 65.9% (95% CI: 34.6% to 104.5%. After adjusting for clinician rated TR and symptom severity, for each unit increase in patient rated TR the odds ratio of good compliance was increased by 20.8% (95% CI: 4.4% to 39.8%. CONCLUSIONS: A better TR is associated with better adherence to medication among patients with schizophrenia. Patients' and clinicians' perspectives of the TR are both important, but may reflect distinct aspects.

    Full Text Available Aim. To investigate predictors of adherence to group-based exercise and physical activity participation among stroke survivors. Methods. 76 stroke survivors participated (mean age 66.7 years. Adherence was the percentage of classes attended over one year. Physical activity was the average pedometer steps/day measured over seven days at the end of the trial. Possible predictors included baseline measures of demographics, health, quality of life, falls, fear of falling, cognition, and physical functioning. Results. Mean class attendance was 60% (SD 29%. Only one variable (slow choice stepping reaction time was an independent predictor of higher class attendance, explaining 5% of the variance. Participants completed an average of 4,365 steps/day (SD 3350. Those with better physical functioning (choice stepping reaction time, postural sway, maximal balance range, 10-m walk, or 6-min walk or better quality of life (SF-12 score took more steps. A model including SF-12, maximal balance range, and 6-min walk accounted for 33% of the variance in average steps/day. Conclusions. The results suggest that better physical functioning and health status are predictors of average steps taken per day in stroke survivors and that predicting adherence to group exercise in this group is difficult.

    2014-01-01

    AIMS: The optimal duration of a public heart failure (HF) clinic programme is unknown. This substudy of the NT-proBNP stratified follow-up in outpatient heart failure clinics (NorthStar) trial was designed to evaluate the effect of extended follow-up in an outpatient HF clinic on long......-term adherence to guideline-based therapy. METHODS AND RESULTS: Patients with HF with reduced EF on optimal medical therapy (n = 921) were randomized to either extended follow-up in the HF clinic (n = 461) or discharge to primary care (n = 460) and followed for a median of 4.1 years (range: 13 months to 6.......30, 95% CI 0.85-2.00, P = 0.238). CONCLUSIONS: Extended follow-up in an outpatient HF clinic did not improve long-term adherence to guideline-based therapy, and adherence did not deteriorate when follow-up was shifted from the HF clinic to primary care....

  13. Sonoporation of adherent cells under regulated ultrasound cavitation conditions.

    Muleki Seya, Pauline; Fouqueray, Manuela; Ngo, Jacqueline; Poizat, Adrien; Inserra, Claude; Béra, Jean-Christophe

    2015-04-01

    A sonoporation device dedicated to the adherent cell monolayer has been implemented with a regulation process allowing the real-time monitoring and control of inertial cavitation activity. Use of the cavitation-regulated device revealed first that adherent cell sonoporation efficiency is related to inertial cavitation activity, without inducing additional cell mortality. Reproducibility is enhanced for the highest sonoporation rates (up to 17%); sonoporation efficiency can reach 26% when advantage is taken of the standing wave acoustic configuration by applying a frequency sweep with ultrasound frequency tuned to the modal acoustic modes of the cavity. This device allows sonoporation of adherent and suspended cells, and the use of regulation allows some environmental parameters such as the temperature of the medium to be overcome, resulting in the possibility of cell sonoporation even at ambient temperature.

    2015-01-01

    This exploratory study examined the degree to which decisional capacity (DC) is associated with measures of self-reported medication adherence. We hypothesized that youth with higher levels of DC would report greater levels of antiretroviral medication adherence. Seventy-two (72) youth with HIV aged 13-24 participated in this study. Data collection included administration of the MacArthur Competence Tool for Treatment and measures of adherence (i.e., seven-day self-report interview, visual analog scale, and biological indicators). Data were analyzed using descriptive statistics, intercorrelations, and multiple and Poisson regression analyses. Youth with HIV who exhibited greater understanding of their disease were more likely to report fewer missed doses in the last seven days. Findings build upon literature in the areas of DC and health literacy and highlight the potential utility of enhancing HIV disease understanding among youth with HIV.

    Campero, Lourdes; Herrera, Cristina; Kendall, Tamil; Caballero, Marta

    2007-05-01

    The goal in this article is to examine social problems associated with highly active antiretroviral therapy (HAART) adherence in Mexico and the related challenges for Mexican persons living with HIV/AIDS (PLWHAs). The study was conducted from the perspective of infected and affected individuals. The authors completed 64 in-depth interviews with heterosexual male and female PLWHAs, as well as with some key individuals from their social network. Following the principles of grounded theory, they carried out inductive analysis to create codes and organize central themes. The authors identified problems related to accessing HAART and found that conditions for implementing recommendations made in the international literature to improve adherence are poor. The findings highlight the importance of social factors, such as health care system irregularities, ineffective physician-patient communication, and availability of family and other sources of social support such as self-help groups for PLWHAs' access and adherence to antiretroviral therapy in Mexico.

  16. Stick to your gums: mechanisms of oral microbial adherence.

    Nobbs, A H; Jenkinson, H F; Jakubovics, N S

    2011-11-01

    Studies on the adherence properties of oral bacteria have been a major focus in microbiology research for several decades. The ability of bacteria to adhere to the variety of surfaces present in the oral cavity, and to become integrated within the resident microbial communities, confers growth and survival properties. Molecular analyses have revealed several families of Gram-positive bacterial surface proteins, including serine-rich repeat, antigen I/II, and pilus families, that mediate adherence to a variety of salivary and oral bacterial receptors. In Gram-negative bacteria, pili, auto-transporters, and extracellular matrix-binding proteins provide components for host tissue recognition and building of complex microbial communities. Future studies will reveal in greater detail the binding pockets for these adhesin families and their receptors. This information will be crucial for the development of new inhibitors or vaccines that target the functional regions of bacterial proteins that are involved in colonization and pathogenesis.

  17. Interventions for enhancing medication compliance/adherence with benefits in treatment outcomes

    Hagen, Anja

    2007-01-01

    Full Text Available Scientific background: Poor compliance or adherence in drug therapy can cause increased morbidity, mortality and enormous costs in the healthcare system (in Germany annually approximately 10 billion euros. Different methods are used for enhancing the compliance or adherence. Research questions: The evaluation addresses the questions about existence, efficacy, cost-benefit relation as well as ethical-social and juridical implications of strategies for enhancing compliance or adherence in drug therapy with concomitant improvements in treatment outcomes. Methods: A systematic literature search was conducted in the medical, also health economic relevant, literature databases in January 2007, beginning from 2002. Systematic reviews on the basis of (randomised controlled trials (RCT concerning interventions to enhance compliance or adherence with regard to treatment outcomes as well as systematic reviews of health economic analyses were included in the evaluation. Additionally, it was also searched for publications which primarily considered ethical-social and juridical aspects of these interventions for the German context. Results: One systematic review with data for 57 RCT was included in the medical evaluation and one systematic review with data for six studies into the health economic evaluation. No publication primary concerning ethical-social or juridical implications could be identified. A significant positive effect on the treatment outcome was reported for 22 evaluated interventions. For many interventions the results can be classified as reliable: counseling with providing an information leaflet and compliance diary chart followed by phone consultation for helicobacter pylori positive patients, repeated counseling for patients with acute asthma symptoms, telephone calls to establish the level of compliance and to make recommendations based on that for the therapy of cardiovascular diseases, calls of an automated telephone system with phone

  18. Association of Continuity of Primary Care and Statin Adherence.

    James R Warren

    Full Text Available Deficiencies in medication adherence are a major barrier to effectiveness of chronic condition management. Continuity of primary care may promote adherence. We assessed the association of continuity of primary care with adherence to long-term medication as exemplified by statins.We linked data from a prospective study of 267,091 Australians aged 45 years and over to national data sets on prescription reimbursements, general practice claims, hospitalisations and deaths. For participants having a statin dispense within 90 days of study entry, we computed medication possession ratio (MPR and usual provider continuity index (UPI for the subsequent two years. We used multivariate Poisson regression to calculate the relative risk (RR and 95% confidence interval (CI for the association between tertiles of UPI and MPR adjusted for socio-demographic and health-related patient factors, including age, gender, remoteness of residence, smoking, alcohol intake, fruit and vegetable intake, physical activity, prior heart disease and speaking a language other than English at home. We performed a comparison approach using propensity score matching on a subset of the sample.36,144 participants were eligible and included in the analysis among whom 58% had UPI greater than 75%. UPI was significantly associated with 5% increased MPR for statin adherence (95% CI 1.04-1.06 for highest versus lowest tertile. Dichotomised analysis using a cut-off of UPI at 75% showed a similar effect size. The association between UPI and statin adherence was independent of socio-demographic and health-related factors. Stratification analyses further showed a stronger association among those who were new to statins (RR 1.33, 95% CI 1.15-1.54.Greater continuity of care has a positive association with medication adherence for statins which is independent of socio-demographic and health-related factors.

  19. Characteristics of HIV antiretroviral regimen and treatment adherence

    Vera Lúcia da Silveira

    2003-06-01

    Full Text Available The relationship between characteristics of HIV antiretroviral regimens and treatment adherence was studied in adolescent and adult patients who underwent antiretroviral therapy from January 1998 to September 2000, at the Service for Specialized Assistance in Pelotas. The patients were interviewed on two occasions, and the use of antiretrovirals during the previous 48 hours was investigated by a self-report. Adherence was defined as use of 95% or more of the prescribed medication. Social-demographic variables were collected through direct questionnaires. The antiretroviral regimen and clinical data were copied from the patients' records. Associations between the independent variables and adherence were analyzed by means of logistic regression. The multivariate analysis included characteristics of the antiretroviral regimens, social-demographic variables, as well as perception of negative effects, negative physiological states, and adverse effects of the treatment. Among the 224 selected patients, 194 participated in our study. Their ages varied from 17 to 67 years; most patients were men, with few years of schooling and a low family income. Only 49% adhered to the treatment. Adherence to treatment regimens was reduced when more daily doses were indicated: three to four doses (odds ratio of adherence to treatment (OR=0.47, 95% confidence interval (CI 0.22-1.01 and five to six (OR=0.24, 95% CI 0.09-0.62; two or more doses taken in a fasting state (OR=0.59, 95% CI 0.11-0.68, and for patients who reported adverse effects to the treatment (OR=0.39, 95% CI 0.19-0.77. Most of the regimens with more than two daily doses of medication included at least one dose apart from mealtimes. The results suggest that, if possible, regimens with a reduced number of doses should be chosen, with no compulsory fasting, and with few adverse effects. Strategies to minimize these effects should be discussed with the patients.

    Background Hypertension (HTN) is an important problem in the United States, with an estimated 78 million Americans aged 20 years and older suffering from this condition. Health disparities related to HTN are common in the United States, with African Americans suffering from greater prevalence of the condition than whites, as well as greater severity, earlier onset, and more complications. Medication adherence is an important component of HTN management, but adherence is often poor, and simply forgetting to take medications is often cited as a reason. Mobile health (mHealth) strategies have the potential to be a low-cost and effective method for improving medication adherence that also has broad reach. Objective Our goal was to determine the feasibility, acceptability, and preliminary clinical effectiveness of BPMED, an intervention designed to improve medication adherence among African Americans with uncontrolled HTN, through fully automated text messaging support. Methods We conducted two parallel, unblinded randomized controlled pilot trials with African-American patients who had uncontrolled HTN, recruited from primary care and emergency department (ED) settings. In each trial, participants were randomized to receive either usual care or the BPMED intervention for one month. Data were collected in-person at baseline and one-month follow-up, assessing the effect on medication adherence, systolic and diastolic blood pressure (SBP and DBP), medication adherence self-efficacy, and participant satisfaction. Data for both randomized controlled pilot trials were analyzed separately and combined. Results A total of 58 primary care and 65 ED participants were recruited with retention rates of 91% (53/58) and 88% (57/65), respectively. BPMED participants consistently showed numerically greater, yet nonsignificant, improvements in measures of medication adherence (mean change 0.9, SD 2.0 vs mean change 0.5, SD 1.5, P=.26), SBP (mean change –12.6, SD 24.0 vs mean change

    Full Text Available Background: Adherence is critical for the effectiveness of antiretroviral HIV therapy (ART, accordingly decreasing the opportunistic diseases and increasing the quality of life. Neurocognitive disorders (NCD are still frequent in ART era and could impair the adherence, but how ethical is to refer ART in patients with NCD? Objective: To assess the relation between NCD and adherence in HIV Romanian patients. Material and methods: Cross-sectional screening study on 151 patients under ART, no drug users, from HIV Clinic - Galati, assessed by HIV-Associated Dementia Scale (HDS, Hospital Anxiety and Depression Scale (HADS [1], ART CNS-effectiveness Letendre scores [2] and adherence assessment questionnaire CNLAS- Romania. Normal values: HDS >10; anxiety/ depression <8. Statistical analysis performed: Chi-square test and Mann-Whitney test, with 5% significance level. Results: Characteristics of the patients: median age 22 [20; 56] years old; sex ratio F/M 1.17; median educational level 8 [0; >12] years; HBV co-infection 27.8%; AIDS stage 85.3%; current median CD4 526/mm3 [8; 1605] and 65% undetectable HIV-RNA levels. 49.6% (75/151 patients attain HDS scores <10 and imply probable NCD. Scores below 8 for anxiety are more frequent than for depression: 24% vs 13%. The median ART CNS penetration score is 8 [5; 12]. Adherence is considered for 66% patients and is correlating with CD4 number (p=0.001, educational level >4 years (p=0.001; OR=4.2, HDS >10 (p=0.01; OR=2.4 and ART-CNS penetration score >7 (p=0.023; OR=2.4. Low HDS are influenced by old age (p=0.003, depression (p=0.02 and ART-CNS penetration scores <7 (p=0.01. Anxiety is related neither with adherence nor with NCD by HDS, but females are obvious anxious than males (p<0.001. Conclusions: Basic educational level is sufficient for developing ART adherence. High scores of HDS screening should be predictors for ART adherence. Referring ART as well to patients with low HDS scores is rational and

  8. A peer adherence support intervention to improve the antiretroviral treatment outcomes of HIV patients in South Africa: the moderating role of family dynamics.

    Wouters, Edwin; Masquillier, Caroline; Ponnet, Koen; le Roux Booysen, Frederik

    2014-07-01

    Given the severe shortage of human resources in the healthcare sector in many countries with high HIV prevalence, community-based peer adherence support is being increasingly cited as an integral part of a sustainable antiretroviral treatment (ART) strategy. However, the available scientific evidence on this topic reports discrepant findings on the effectiveness of peer adherence support programmes. These conflicting findings to some extent can be attributed to the lack of attention to the social contexts in which peer adherence support programmes are implemented. This study explores the potential moderating role of family dynamics by assessing the differential impact of peer adherence support in different types of families, based on the theoretical underpinnings of the family functioning framework. These relationships were explored with the aid of multivariate statistical analysis of cross-sectional, post-trial data for a sample of 340 patients interviewed as part of the Effectiveness of Aids Treatment and Support in the Free State (FEATS) study conducted in the public-sector ART programme of the Free State Province of South Africa. The analysis reveals no significant overall differences in CD4 cell count between the intervention group accessing additional peer adherence support and the control group receiving standard care. When controlling for the potential moderating role of family dynamics, however, the outcomes clearly reveal a significant interaction effect between the adherence intervention and the level of family functioning with regard to treatment outcomes. Multi-group analysis demonstrates that peer adherence support has a positive effect on immunological restoration in well-functioning families, while having a negative effect in dysfunctional families. The study outcomes stress the need for peer adherence interventions that are sensitive to the suboptimal contexts in which they are often implemented. Generic, broad-based interventions do not

We aimed to produce motivational posters to support nebulizer adherence by using social marketing involving people with CF in the development of those posters. Methods: The Sheffield CF multidisciplinary team produced preliminary ideas that were elaborated upon with semi-structured interviews among people with CF to explore barriers and facilitators to the use of nebulized therapy. Initial themes and poster designs were refined using an online focus group to finalize the poster designs. Results: People with CF preferred aspirational posters describing what could be achieved through adherence in contrast to posters that highlighted the adverse consequences of nonadherence. A total of 14 posters were produced through this process. Conclusion: People with CF can be engaged to develop promotional material to support adherence, providing a unique perspective differing from that of the CF multidisciplinary team. Further research is needed to evaluate the effectiveness of these posters to support nebulizer adherence.

  10. Preexposure prophylaxis-related stigma: strategies to improve uptake and adherence – a narrative review

    Haire BG

    2015-10-01

    Full Text Available Bridget G Haire Kirby Institute for Infection and Immunity in Society, University of New South Wales, Sydney, NSW, Australia Abstract: Despite high levels of efficacy, the implementation of preexposure prophylaxis (PrEP as a strategy to prevent new HIV infection has been slow. Studies show that PrEP works so long as it is taken, making adherence one of the great challenges of effective PrEP implementation alongside issues of access and uptake. Given that effective PrEP use requires ongoing self-administration of pills by people at high risk of HIV acquisition, it is a strategy best understood not as simply biomedical, but as biobehavioral or biopsychosocial, meaning that that social, psychological, cultural, and structural factors all contribute to the success or failure of the intervention. The willingness of people at risk of HIV to take up and adhere to PrEP depends greatly upon social understandings – whether it is seen as effective, as a healthy option, and a socially acceptable strategy for preventing HIV. Stigma – unfavorable associations – can negatively influence the implementation of PrEP. Because it is associated with high-risk sexual activity, PrEP risks multiple stigmas that can differ according to specific cultural conditions. This includes the stigma of being related to HIV (which may also relate to other stigmas, such as homosexuality, sex work, and/or drug use and the stigma of PrEP being an alternative to condoms (as condom use is associated with responsible sexual activity. PrEP-related stigma has emerged as a significant social harm that can arise from PrEP research participation, reported by trial participants from a range of different trial sites, different trial populations, and spanning different continents. Social marketing needs to redress PrEP-related stigmas through health promotion campaigns aimed at clinicians, HIV-affected communities, and people at high risk of HIV who might benefit from PrEP access.

    2017-01-01

    Background Adherence to medication is vital for disease management while simultaneously reducing healthcare expenditure. Older persons with cognitive impairment (CI) are at risk for non-adherence as cognitive processes are needed to manage medications. This systematic review focuses on the relationship between medication non-adherence and specific cognitive domains in persons with CI, and explores determinants of medication non-adherence. When available, relationships and factors are compared with cognitively intact populations. Methods A seven database systematic search of studies published between 1 January 1949–31 December 2015 examining medication non-adherence in community dwelling persons with CI or dementia was conducted. Articles reporting medication non-adherence in people with CI or dementia in the community, with or without caregiver supports were eligible for inclusion. Papers reporting adherence to treatments in cognitively intact populations, populations from hospital or institutional settings, for non-prescribed medication or those describing dementia as a factor predicting medication non-adherence were excluded. Data on study and population characteristics, research design, data sources and analysis, specific cognitive domains, non-adherence prevalence, measurement of adherence, salient findings, factors associated with adherence and strategies to improve medication adherence were extracted. Study limitations included inconsistencies between data sources and definitions, resulting in a loss of fidelity in the value and comprehensiveness of data, as well as exclusion of non-pharmacological treatments and regimens. Findings Fifteen studies met inclusion criteria. Adherence among CI subjects ranged from 10.7%-38% with better rates of adherence in non-CI individuals. Medication non-adherence definitions varied considerably. New-learning, memory and executive functioning were associated with improved adherence and formed the focus of most studies

    Highlights: Black-Right-Pointing-Pointer Chitosan silica magnetite adsorbs antineoplastic drug. Black-Right-Pointing-Pointer Silica coating improve the drug adherence. - Abstract: Cancer treatment is a big challenge in medicine where chemotherapies and radiotherapies are aggressive and poorly effective having side effects as delirium, fatigue, insomnia, nausea and vomiting which are common problems for cancer patients. For this reason, during the last two decades, many researchers have developed several techniques to improve the current therapies; one of them is the functionalization of magnetic nanoparticles for drug delivery. In this work, magnetic nanoparticles with an average crystallite size 21.8 nm were covered in a core/shell type; magnetite/silica, magnetite/chitosan, and a double shell magnetite/silica/chitosan were developed for attaching an antineoplastic drug. The mechanism for the functionalization of the nanoparticles with a single and double shell was studied with Fourier transformed infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). The adherence of an antineoplastic drug, paclitaxel, onto functionalized nanoparticles was analyzed with a UV-Visible spectroscopy at a wavelength of 253 nm. It was found that the adherence of the drug is improved up to 18% when magnetite nanoparticles are coated with a single chitosan shell, and when the nanoparticles are coated with a silica/chitosan shell the adherence increases up to 29%.

    ABSTRACT Objective: to test the effects of behavioral and educational intervention by telephone on adherence of women with inappropriate periodicity to colpocytological examination. Method: quasi-experimental study with a sample of 524 women, selected with the following inclusion criteria: be aged between 25 and 64 years, have initiated sexual activity, have inappropriate periodicity of examination and have mobile or landline phone. The women were divided into two groups for application of behavioral and educational intervention by telephone. It was used an intervention script according to the principles of Motivational Interviewing. Results: on comparing the results before and after the behavioral and educational interventions, it was found that there was a statistically significant change (p = 0.0283) with increase of knowledge of women who participated in the educational intervention. There was no change in the attitude of women of any of the groups and there was an increase of adherence to colpocytological examination in both groups (p < 0.0001), with greater adherence of women participating in the behavioral group (66.8%). Conclusion: the behavioral and educational interventions by phone were effective in the adherence of women to colpocytological examination, representing important strategies for permanent health education and promotion of care for the prevention of cervical cancer.

Significant progress has been made in the treatment of noninfectious uveitis in recent years, particularly with regard to the effective use of corticosteroids and non-corticosteroid immunosuppressive drugs, including biologic agents. All of these therapeutic approaches are limited, however, by any given patient’s ability to comply with and adhere to their prescribed treatment. In fact, compliance and adherence are among the most important patient-related determinants of treatment success. We discuss strategies to optimize compliance and adherence.

    Deighton, M A; Balkau, B

    1990-11-01

    Staphylococcus epidermidis strains isolated from clinical sources showed a wide range of abilities to adhere to glass and plastic materials. The degree of adherence depended on a number of factors, most notably, the composition of the growth medium. Adherence was enhanced by the addition of glucose or oleic acid to the growth medium and inhibited by serum. We have demonstrated a statistically significant association between the quantitative assessment of adherence to polystyrene tissue culture plates and clinical relevance. No such association was found when adherence was assessed by the qualitative adherence assay. Possible new approaches for assessing the clinical relevance of coagulase-negative staphylococcal isolates are discussed.

The study is the first to show high adherence rates to infliximab in a pediatric cohort.

  9. Use of a Novel Artificial Intelligence Platform on Mobile Devices to Assess Dosing Compliance in a Phase 2 Clinical Trial in Subjects With Schizophrenia

    2017-01-01

    Background Accurately monitoring and collecting drug adherence data can allow for better understanding and interpretation of the outcomes of clinical trials. Most clinical trials use a combination of pill counts and self-reported data to measure drug adherence, despite the drawbacks of relying on these types of indirect measures. It is assumed that doses are taken, but the exact timing of these events is often incomplete and imprecise. Objective The objective of this pilot study was to evaluate the use of a novel artificial intelligence (AI) platform (AiCure) on mobile devices for measuring medication adherence, compared with modified directly observed therapy (mDOT) in a substudy of a Phase 2 trial of the α7 nicotinic receptor agonist (ABT-126) in subjects with schizophrenia. Methods AI platform generated adherence measures were compared with adherence inferred from drug concentration measurements. Results The mean cumulative pharmacokinetic adherence over 24 weeks was 89.7% (standard deviation [SD] 24.92) for subjects receiving ABT-126 who were monitored using the AI platform, compared with 71.9% (SD 39.81) for subjects receiving ABT-126 who were monitored by mDOT. The difference was 17.9% (95% CI -2 to 37.7; P=.08). Conclusions Using drug levels, this substudy demonstrates the potential of AI platforms to increase adherence, rapidly detect nonadherence, and predict future nonadherence. Subjects monitored using the AI platform demonstrated a percentage change in adherence of 25% over the mDOT group. Subjects were able to use the technology successfully for up to 6 months in an ambulatory setting with early termination rates that are comparable to subjects outside of the substudy.

    Low adherence to antihypertensive medication has been hypothesized to increase visit-to-visit variability (VVV) of blood pressure (BP). We assessed the association between antihypertensive medication adherence and VVV of BP in the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT). VVV of BP was calculated using SD independent of mean, SD, and average real variability across study visits conducted 6 to 28 months after randomization. Participants who reported taking heart disease or nonfatal myocardial infarction, stroke, heart failure, or mortality risk. In conclusion, improving medication adherence may lower VVV of BP. However, VVV of BP is associated with cardiovascular outcomes independent of medication adherence.

    Full Text Available Objective: The scope of this article is to describe the background for and content of an adherence counselling programme with a specific focus on an individualised, multi-dimensional adherence model for patients with a potential adherence problem (a so-called ‘individualised systems model’.Methods: An intervention programme based on WHO’s systems model for adherence was developed for implementation in primary health care and tested in a development project in Danish pharmacies in 2004-2005 in three pharmacies and 4 GP practices by 27 patients. Data were collected from the participants by registration forms, questionnaires, and focus groups. Since the programme was to support patients in the self-management process regarding choice and implementation of medication treatment, various strategies were used and different theoretical assumptions and choices made prior to setting up the study. These strategies include distinguishing between different types of non-adherence, a model for stages of change, self-efficacy, narratives, motivating interviewing strategies and coaching techniques. These strategic and theoretical choices are described in the article. Results: The strategies and theoretical reflections formed the platform for the creation of a counselling programme, which was tested in two forms, a basic and an extended version - provided by either a pharmaconomist or a pharmacist. The result section also describes a toolbox of instruments to enable pharmacy staff and GPs to tailor a counselling programme for patients individually called ‘Safe and effective use of medicines’. Besides, the results include a description of how the WHO-model is transformed into an individualised counselling model.

The intervention consisted of a single, 50-minute problem-solving cognitive-behavioural intervention session with four skill-based booster sessions, delivered by four lay adherence counsellors in the context of HIV care. Adaptation followed a theoretically driven approach to intervention adaptation, Assessment-Decision-Administration-Production-Topical Experts-Integration-Training-Testing (ADAPT-ITT), and included modifications to language, session length, tailoring content for delivery by lay counsellors and inclusion of culturally competent probes. The feasibility of the intervention was evaluated using a mixed-methods assessment, including ratings of provider fidelity of intervention delivery, and qualitative assessments of feasibility using individual semi-structured interviews with counsellors (n = 4) and patients (n = 15). The intervention was feasible and acceptable when administered to 42 patients and resulted in improved self-reported adherence in a subset of 15 patients who were followed up after 6 months. Next steps from this study include conducting a randomised control trial to evaluate the adapted intervention compared to standard of care in a larger sample over a long-term follow-up.

  14. ART adherence changes among patients in community substance use treatment: a preliminary analysis from MACH14

    Rosen Marc I

    2012-10-01

    Full Text Available Abstract Background Opiate substitution treatment has been associated with better adherence to lifesaving antiretroviral medications, but the impact of other substance abuse treatment on adherence is unknown. Findings In this study, 215 patients who had been in adherence-focused research studies provided electronically-measured adherence data and a measure of whether the patient had recently been in substance abuse treatment. Recent engagement in substance abuse treatment was independently associated with significantly higher adherence, after covarying for recent substance use and other factors potentially affecting adherence. Conclusions The findings suggest that substance abuse treatment is associated with better adherence. Potential mechanisms by which substance abuse treatment improves adherence, such as more stability or more future-orientation, require further study.

  16. Can the common-sense model predict adherence in chronically ill patients? A meta-analysis.

    Brandes, Kim; Mullan, Barbara

    2014-01-01

    The aim of this meta-analysis was to explore whether mental representations, derived from the common-sense model of illness representations (CSM), were able to predict adherence in chronically ill patients. Electronic databases were searched for studies that used the CSM and measured adherence behaviour in chronically ill patients. Correlations from the included articles were meta-analysed using a random-size effect model. A moderation analysis was conducted for the type of adherence behaviour. The effect sizes for the different mental representations and adherence constructs ranged from -0.02 to 0.12. Further analyses showed that the relationship between the mental representations and adherence did not differ by the type of adherence behaviour. The low-effect sizes indicate that the relationships between the different mental representations of the CSM and adherence are very weak. Therefore, the CSM may not be the most appropriate model to use in predictive studies of adherence.

  17. Adherence of Pseudomonas aeruginosa to tracheal cells injured by influenza infection or by endotracheal intubation.

    Ramphal, R; Small, P M; Shands, J W; Fischlschweiger, W; Small, P A

    1980-02-01

    Adherence of Pseudomonas aeruginosa to normal, injured, and regenerating tracheal mucosa was examined by scanning electron microscopy. Uninfected and influenza-infected murine tracheas were exposed to six strains of P. aeruginosa isolated from human sources and one strain of platn origin. All of the strains tested adhered to desquamating cells of the infected tracheas, but not to normal mucosa, the basal cell layer, or the regenerating epithelium. Adherence increased when the incubation time of the bacteria with the trachea was prolonged. Strains isolated from human tracheas appeared to adhere better than strains derived from the urinary tract. After endotracheal intubation of ferrets, P. aeruginosa adhered only to the injured cells and to areas of exposed basement membrane. We call this phenomenon "opportunistic adherence" and propose that alteration of the cell surfaces or cell injury facilitates the adherence of this bacterium and that adherence to injured cells may be a key to the pathogenesis of opportunistic Pseudomonas infections.

  19. Adherence to a Yoga Program in Older Women with Knee Osteoarthritis.

    Cheung, Corjena; Wyman, Jean F; Savik, Kay

    2016-04-01

    Yoga is beneficial for osteoarthritis (OA) management in older adults; however, adherence to yoga practice is unknown. The purposes of this secondary analysis were to examine: (1) yoga adherence during the intervention and follow-up periods; (2) the relationship between social cognitive theory (SCT) constructs and adherence; and (3) the impact of adherence on OA-related symptoms in 36 community-dwelling older women with knee OA. SCT was used as a framework to promote adherence to a yoga intervention program that included both group/homebased practices. Adherence to yoga was high during the intervention period but decreased over time. Although SCT was a useful framework for reducing attrition during the intervention, self-efficacy was the only construct that correlated with class attendance. Higher yoga adherence was correlated with improved symptoms, physical function, sleep quality, and quality of life. Yoga adherers were likely to be older, less educated, and had a lower body mass index than nonadherers.

  20. Mobile phone text messaging for promoting adherence to anti-tuberculosis treatment: a systematic review protocol

    2013-01-01

    Full Text Available Abstract Background In 2010, there were approximately 8.8 million incident cases of tuberculosis (TB worldwide. The treatment of TB is at least six months long and may be complicated by a high pill burden. In addition, TB patients often do not take their medication on schedule simply because they forget. Mobile phone text messaging has the potential to help promote TB treatment adherence. We, therefore, propose to conduct a review of current best evidence for the use of mobile phone text messaging to promote patient adherence to TB treatment. Methods This is a systematic review of the literature. We will preferably include randomized controlled trials (RCTs. However, non-randomized studies (NRS will be considered if there is an inadequate number of RCTs. We will search PubMed, EMBASE, CINAHL, CENTRAL, Science Citation Index, Africa-Wide Information, and WHOLIS electronic databases for eligible studies available by 30 November 2012 regardless of language or publication status. We will also check reference lists for additional studies, identify abstracts from conference proceedings and communicate with authors for any relevant material. At least two authors will independently screen search outputs, select studies, extract data and assess the risk of bias (using separate criteria for RCTs and NRS; resolving discrepancies by discussion and consensus. We will assess clinical heterogeneity by examining the types of participants, interventions and outcomes in each study and pool studies judged to be clinically homogenous. We will also assess statistical heterogeneity using the chi-square test of homogeneity and quantify it using the I-square statistic. If study results are found to be statistically homogeneous (that is heterogeneity P > 0.1, we will pool them using the fixed-effect meta-analysis. Otherwise, we will use random-effects meta-analysis. We will calculate risk ratios and their corresponding 95% confidence intervals for dichotomous outcomes

    Full Text Available The aim of this study was to determine adherence and attrition rates in a lifestyle intervention for people with metabolic syndrome.Adherence and attrition data from a randomized controlled trial were collected. Participants were classified as adherence group if they completed assessments at 3 and 6 months follow-up and as attrition group if they did not. Physical activity and quality of life was measured using the International Physical Activity Questionnaire (IPAQ and the Short Form Health Survey (SF-36. Generalized Estimating Equations (GEE was used to explore predictors of attrition.The mean age of participants (n=160 was 44.1 years. Attrition rate in the intervention and control groups at first follow-up were the same (20%. However, the control group had significantly higher attrition rate (%33.7 compared to the intervention group (%20 at 6 months follow up. Results showed that low educated participants were more likely to not stay in the study than better educated participants (OR=2.95,CI:1.39-6.33,P=0.05. According with length of the study, attrition was decreased at six month (OR=0.66,CI:0.52-0.83,P<0.001. Also, some aspects of health-related quality of life contributed to the attrition rate. Those who had higher scores on general health (OR=0.66,CI:0.54-0.97,P=0.023, social functioning (OR=0.44,CI:0.40-0.76,P=0.032, role emotional (OR=0.74,CI:0.54-0.98,P=0.18, vitality (OR=0.55,CI:0.38-0.90,P=0.015 and mental health (OR=0.63,CI:0.45-0.85,P=0.033 were more likely to stay in the study.It remains a concern that Web-based lifestyle programs may fail to reach those who need it most. Participant in the study generally had better quality of life than those who were lost to follow up.

Nonadherence to medical plans affects every level of the population, but particularly older adults due to the high number of coexisting diseases they are affected by and the consequent polypharmacy. Chronic disease management requires a continuous psychological adaptation and behavioral reorganization. In literature, many interventions to improve medication adherence have been described for different clinical conditions, however, most interventions seem to fail in their aims. Moreover, most interventions associated with adherence improvements are not associated with improvements in other outcomes. Indeed, in the last decades, the degree of nonadherence remained unchanged.

  8. Adherence to a flexible extended regimen for oral hormonal contraception provided in blister packaging compared with an adherence-supporting digital tablet dispenser: historical comparison of data from two clinical studies

    Elliesen, Jörg; Trummer, Dietmar

    2016-01-01

    Background The Clyk™ digital pill dispenser helps ensure correct and consistent administration of a flexible extended regimen of the combined oral contraceptive, ethinylestradiol (EE) 20 μg/drospirenone 3 mg (EE/drospirenone ; YAZ® Flex Flex), guiding users through the intake cycle and 4-day pill break and providing visible and acoustic daily reminders when pill intake is due. A study showed that the audible alarm function of the dispenser could help reduce the number of missed pills, but it lacked an appropriate “non-dispenser” group for a meaningful assessment of the impact of the dispenser on adherence. This study indirectly assessed the overall effect of the digital dispenser on adherence by comparing data from a treatment with standard blister packaging. Materials and methods One-year adherence data were compared from two similarly designed, Phase III, open-label, randomized trials of EE/drospirenoneFlex. In study 1, women used diary cards to record adherence with EE/drospirenoneFlex dispensed in blister packs (n=640), and in study 2 the dispenser was used with the alarm activated (n=250) or deactivated (n=248) in addition to using diary cards. Results A mean (±SD) of 4.3 (±4.24) missed pills over 1 year were recorded in diary cards among women who dispensed their pills from the blister packages (study 1) compared with 1.0 (±2.4) recorded by the alarm-activated dispenser (study 2). In study 2, a mean of 1.9 (±4.2) missed pills were reported in the diaries over 1 year compared with 4.4 (±9.1) from automatic recording by the dispenser (both arms of study 2), indicating underreporting of missed pills in diary cards vs the digital dispenser. Adjusting for this rate of underreporting, an estimated mean of ten pills were missed over 1 year by women using EE/drospirenoneFlex in blister packs, or ten times more than with the digital dispenser with activated acoustic alarm. Conclusion The digital dispenser helps reduce the number of missed pills and

    Phillips, L. Alison; Leventhal, Elaine A.; Leventhal, Howard

    2011-01-01

    Objective Physicians are inaccurate in predicting non-adherence in patients, a problem that interferes with physicians’: 1) appropriate prescribing decisions and 2) effective prevention/intervention of non-adherence. The purpose of the current study is to investigate potential reasons for the poor accuracy of physicians’ adherence-predictions and conditions under which their predictions may be more accurate. Methods After the medical encounter, predictions of patient-adherence and other ratings from primary-care physicians (n=24) regarding patient-factors that may have influenced their predictions were collected. Patients (n=288) rated their agreement regarding the prescribed treatment after the encounter and reported adherence one month later. Results Several factors were related to physicians’ adherence-predictions, including physicians’ perceptions of patient-agreement regarding treatment. However, some factors were not related to adherence and agreement-perceptions were inaccurate overall, potentially contributing to the poor accuracy of adherence-predictions. The degree to which physicians discussed treatment-specifics with the patient moderated agreement-perception accuracy but not adherence-prediction accuracy. Conclusions Training providers to discuss certain treatment-specifics with patients may improve their ability to perceive patient-agreement regarding treatment and may directly improve patient-adherence. Practice Implications Discussing treatment-specifics with patients may directly improve adherence, but providers should not rely on these discussions to give them accurate estimates of the patients’ likely adherence.

  15. Identifying solutions to medication adherence in the visually impaired elderly.

    Smith, Miranda; Bailey, Trista

    2014-02-01

    Adults older than 65 years of age with vision impairment are more likely to have difficulty managing medications compared with people having normal vision. This patient population has difficulty reading medication information and may take the wrong medication or incorrect doses of medication, resulting in serious consequences, including overdose or inadequate treatment of health problems. Visually impaired patients report increased anxiety related to medication management and must rely on others to obtain necessary drug information. Pharmacists have a unique opportunity to pursue accurate medication adherence in this special population. This article reviews literature illustrating how severe medication mismanagement can occur in the visually impaired elderly and presents resources and solutions for pharmacists to take a larger role in adherence management in this population.

  17. Optimal shapes and stresses of adherent cells on patterned substrates

    Banerjee, Shiladitya; Marchetti, M Cristina

    2013-01-01

    We investigate a continuum mechanical model for an adherent cell on two dimensional adhesive micropatterned substrates. The cell is modeled as an isotropic and homogeneous elastic material subject to uniform internal contractile stresses. The build-up of tension from cortical actin bundles at the cell periphery is incorporated by introducing an energy cost for bending of the cell boundary, resulting to a resistance to changes in local curvature. Integrin-based adhesions are modeled as harmonic springs, that pin the cell to adhesive patches of a predefined geometry. Using Monte Carlo simulations and analytical techniques we investigate the competing effects of bulk contractility and cortical bending rigidity in regulating cell shapes on non-adherent regions. We show that the crossover from convex to concave cell edges is controlled by the interplay between contractile stresses and boundary bending rigidity. In particular, the cell boundary becomes concave beyond a critical value of the contractile stress that ...

  18. Metacognition and medication adherence: how do older adults remember?

    Gould, O N; McDonald-Miszczak, L; King, B

    1997-01-01

    Fifty-one older adults (M age = 75.9 years, SD = 6.9) reported their use of memory strategies for taking of medication using the Prospective Memory for Medication Questionnaire. Older adults used internal strategies more often when the domain was restricted to medication taking but used external strategies more often when queried across a variety of everyday situations. Surprisingly, the hypothesis that medical factors would be the primary determinants of older adults' reports of memory strategy use and perceived adherence was not supported. Metamemorial variables of non-domain-specific memory self-efficacy and memory anxiety in everyday life were significant predictors of strategy use and perceived adherence over and above variables related to the domain of health.

  19. Asthma Education, Action Plans, Psychosocial Issues and Adherence

    John Kolbe

    1999-01-01

    Full Text Available This article deals with four separate but not disparate topics. The first section discusses asthma education, reviews the current literature and attempts to challenge some of the dogma that is associated with this area. Knowledge alone does not guarantee appropriate behaviour, due to a variety of adverse socioeconomic and psychological factors that need to be considered for each patient. Action plans and peak flow monitoring have both been disappointing in terms of reducing asthma morbidity; the former needs to be individualized, and the latter may be useful in specific situations. Space precludes an in-depth discussion of psychological issues and adherence, but an attempt has been made to address salient issues, particularly related to the first two topics. Psychological factors, especially anxiety, play an important role in asthma outcome. Adherence to medication prescriptions and other management strategies need to be taken into account when an individual’s treatment program is planned.

    de Souza, Bianca Fresche; Pires, Flavia Helena; Dewulf, Nathalie de Lourdes Souza; Inocenti, Aline; Silva, Ana Elisa Bauer de Camargo; Miasso, Adriana Inocenti

    2013-02-01

    This analytical, cross-sectional study applied a quantitative approach to verify the presence of depression and the adherence to a chemotherapy treatment in patients with cancer at the central chemotherapy pharmacy of a university hospital. The sample consisted of 102 patients, and data were collected from October 2010 to May 2011. A structured interview was used to obtain sociodemographic, clinical and therapeutic data; the Morisky Test and Beck Depression Inventory were also applied. The results revealed that 10.8% and 1.9% of participants had moderate and severe depression, respectively. The presence of depression was significantly associated with variables such as income per capita, the number of surgeries, and disease duration. A lack of treatment adherence was identified in 48% of participants. These results indicate the need for health staff training to detect depressive disorders and chemotherapy treatment attrition among patients with cancer.

  1. Control and adherence: living with diabetes in Bangkok, Thailand.

    Naemiratch, Bhensri; Manderson, Lenore

    2006-09-01

    Diabetes is managed via a regimen of control. Physicians advise adults living with type 2 diabetes to control blood sugar levels by controlling diet, maintaining regular exercise, and complying with medication. The extent to which individuals are able to adhere to such recommendations varies. In this article, we explore lay perceptions of diabetes and its control, drawing on data from an ethnographic study conducted in Bangkok, Thailand. Between August 2001 and February 2003 the first author spent time with twelve man and women living with type 2 diabetes, their spouses, children and health providers. An additional 21 people were interviewed to extend the data and test for generalisibility. It was found that individual explanations of control, and adherence or resistance to medical advice, are interpreted and adapted in ways consistent with Buddhist philosophy and Thai norms that govern everyday life. Notions of moderation and cultural values of being and behaving, and ideals of interaction, provide a philosophical basis and practical guidelines for control.

  2. Is adherence a relevant issue in the self-management education of diabetes? A mixed narrative review

    Debussche X

    2014-07-01

    Full Text Available Xavier Debussche Endocrinology, Diabetology and Nutrition, CHU Félix Guyon, Saint-Denis, Réunion, France Abstract: While therapeutic patient education is now recognized as essential for optimizing the control of chronic diseases and patient well-being, adherence to treatment and medical recommendations is still a matter of debate. In type 2 diabetes, the nonadherence to therapy, estimated at more than 40%, is perceived as a barrier for improving the prognosis despite recent therapeutic advances. Interventional studies have barely begun to demonstrate the effectiveness of technical and behavioral actions. The aim of this review is to question the concept of adherence in terms of therapeutic education based on quantitative and qualitative data. The research on therapeutic education has shown the effectiveness of structured actions in type 2 diabetes, but adherence is rarely an end point in randomized trials. A positive but inconsistent or moderate effect of education actions on adherence has been shown in heterogeneous studies of varying quality. Program types, outlines, theoretical bases, and curricula to set up for action effectiveness are still being discussed. Qualitative studies, including sociological studies, provide a useful and constructive focus on this perspective. Adherence is a soft and flexible tool available to the patient in his/her singular chronic disease trajectory, and as such, integrates into individual therapeutic strategies, including socio-cultural interactions, beyond the medical explanation of the disease and the patient. Four key elements for the development of structured therapeutic education are discussed: 1 the access to health literacy, 2 the contextualization of education activities, 3 the long-term chronic dimension of self-management, and 4 the organizational aspects of health and care. Rather than focusing the objective on behavioral changes, structured therapeutic education actions should attempt to provide

    Nuñez, Matías; Prado, Miguel Oscar

    The adherence of "model molecules" methylene blue and eosine Y ("positive" and "negatively" charged respectively) to crystal SiO2 surfaces is studied from first principle calculations at the DFT level. Adsorption energies are calculated which follow the experimental threads obtained elsewhere (Rivera et al., 2013). We study the quantum nature of the electronic charge transfer between the surface and the molecules, showing the localized and delocalized patterns associated to the repulsive and attractive case respectively.

    In this study we report the underlying reasons to why bacteria are present on banknotes and coins. Despite the use of credit cards, mobile phone apps, near-field-communication systems, and cryptocurrencies such as bitcoins which are replacing the use of hard currencies, cash exchanges still make up a significant means of exchange for a wide range of purchases. The literature is awash with data that highlights that both coins and banknotes are frequently identified as fomites for a wide range of microorganisms. However, most of these publications fail to provide any insight into the extent to which bacteria adhere and persist on money. We treated the various currencies used in this study as microcosms, and the bacterial loading from human hands as the corresponding microbiome. We show that the substrate from which banknotes are produced have a significant influence on both the survival and adherence of bacteria to banknotes. Smooth, polymer surfaces provide a poor means of adherence and survival, while coarser and more fibrous surfaces provide strong bacterial adherence and an environment to survive on. Coins were found to be strongly inhibitory to bacteria with a relatively rapid decline in survival on almost all coin surfaces tested. The inhibitory influence of coins was demonstrated through the use of antimicrobial disks made from coins. Despite the toxic effects of coins on many bacteria, bacteria do have the ability to adapt to the presence of coins in their environment which goes some way to explain the persistent presence of low levels of bacteria on coins in circulation.

  8. The adherence in the union stone-mortar

    Rodríguez García, María Reyes

    1994-06-01

    Full Text Available Stones placates present a wide of problems that result in the fall of plates. One of the causes is the lack of adherence stone-mortar. We considered a study to determine the adherence between several cement mortars (1:3, 1:5, 1:7, 1:9 and a especial mortar prepared with latex and stones (white granite, pink granites, black granites, white marble and cream limestones. The results obtained suggest that only adequate adherence rates (higher than 3 kgf/cm2 achieved with cement mortar 1:3 and especial mortar. Besides it is observed that in the stones studied there is no relation between adherence and the absorption values.

    Los aplacados de piedra presentan una extensa patología que se traduce en la caída de las placas colocadas. Una de las causas es la falta de adherencia mortero-piedra. El estudio se realiza para determinar la tensión de adherencia entre diversos morteros de cemento (1:3, 1:5, 1:7, 1:9 y otro compuesto por mortero y látex y piedras (granito blanco, granitos rosa, granitos negros, mármol blanco y calizas crema. De los resultados obtenidos se deduce que los únicos morteros que permiten valores de adherencia aceptables (superiores a 3 kp/cm2 son el mortero de cemento 1:3 y el especial. Igualmente se comprueba que, en las piedras estudiadas, no existe relación alguna entre la adherencia y la absorción de agua.

    Conflicting medication information has been defined as contradictory information about a medication topic from two or more sources. The objective of this study was to determine whether arthritis patients are exposed to conflicting medication information, to document sources of conflicting information, and to explore whether conflicting information is associated with sociodemographic factors, clinical characteristics, and medication adherence. Using an online survey, arthritis patients (N = 328) reported how often they received conflicting information about 12 medication topics as well as sources of conflicting information, demographic/clinical characteristics, and medication adherence. A linear regression model, which controlled for various demographic/clinical factors, determined whether conflicting information was associated with medication adherence. The majority of patients (80.1%) received conflicting information and were most likely to receive conflicting information about medication risks. Physicians, media sources, and the Internet were the most common sources of conflicting information. Less conflicting information (B =-0.13, p information source use (B = 0.22, p information is pervasive, comes from a variety of sources, and may negatively affect patient health outcomes. To potentially decrease exposure to conflicting information, providers should direct patients to high-quality medication information sources.

    Stainless steel is one of the most common metallic biomedical materials. For medical applications, its resistance to the adherence of biofilms is of importance to the elimination or minimization of bacterial infections. In this study, we demonstrate the effectiveness of a process combining surface nanocrystallization and thermal oxidation (or a recovery heat treatment in air) for reducing the biofilm's adherence to stainless steel. During this treatment, a target surface was sandblasted and the resultant dislocation cells in the surface layer were turned into nanosized grains by a subsequent recovery treatment in air. This process generated a more protective oxide film that blocked the electron exchange or reduced the surface activity more effectively. As a result, the biofilm's adherence to the treated surface was markedly minimized. A synthetic peptide was utilized as a substitute of biofilms to evaluate the adhesion between a treated steel surface and biofilms using an atomic force microscope (AFM) through measuring the adhesive force between the target surface and a peptide-coated AFM tip. It was shown that the adhesive force decreased with a decrease in the grain size of the steel. The corresponding surface electron work function (EWF) of the steel was also measured, which showed a trend of variation in EWF with the grain size, consistent with corresponding changes in the adhesive force.

  11. Adherence to Informed Consent Standards in Shiraz Hospitals: Matrons Perspective

    Alireza Mohsenian Sisakht

    2015-01-01

    Full Text Available Background Informed consent is an important part of the patients’ rights and hospitals are assigned to obtain informed consent before any diagnostic or therapeutic procedures. Obtaining an informed consent enables patients to accept or reject their care or treatments and prevent future contentions among patients and medical staff. Methods This survey was carried out during 2011-2. We assessed adherence of 33 Shiraz hospitals (governmental and non-governmental to informed consent standards defined by Joint Commission International (JCI Accreditation, USA. The questionnaire was designed using the Delphi method and then filled out by hospital matrons. We calculated valid percent frequency for each part of the questionnaire and compared these frequencies in governmental and nongovernmental hospitals using analytical statistics. Results Considering 63% of the hospitals that filled out the questionnaire, no statistically significant difference was observed between the governmental and non-governmental hospitals in adherence to informed consent standards. Conclusion This study shows a relatively acceptable adherence to standards about informed consent in Shiraz hospitals but the implementation seems not to be as satisfactory.

    2012-11-01

    An investigation into the effect of clinical ultrasound exposure on adherent microbubbles is described. A flow phantom was constructed in which targeted microbubbles were attached using biotin-streptavidin linkages. Microbubbles were insonated by broadband imaging pulses (centred at 2.25 MHz) over a range of pressures (peak negative pressure (PNP) = 60-375 kPa). Individual adherent bubbles were observed optically and classified as either being isolated or with a single neighbouring bubble. It is found that bubble detachment and deflation are two significant effects, even during low amplitude ultrasound exposure. Specifically, while at very low acoustic pressure (PNP bubbles were not affected, at medium pressure (151 kPa bubbles detached and at higher pressures (301 kPa bubbles detached. In addition, more than 50% of the bubbles underwent deflation at pressures between 301 and 375 kPa. At pressures between 226 and 300 kPa, more adherent bubbles detached when there was a neighbouring bubble, suggesting the role of multiple scattering and secondary Bjerknes force on bubble detachment. The flow shear, primary and secondary Bjerknes forces exerted on each bubble were calculated and compared to the estimated forces acting on the bubble due to oscillations. The oscillation force is shown to be much higher than other forces. The mechanisms of bubble detachment are discussed.

    Full Text Available L Bellamy1, N Rosencher1, BI Eriksson21Anaesthesiology Department, Hôpital Cochin (AP-HP, René Descartes University, Paris 75014 France; 2Orthopaedic Department, University Hospital Sahlgrenska/Ostra, Gothenburg, SwedenAbstract: The recent development of new oral anticoagulants, of which dabigatran etexilate is currently at the most advanced stage of development, is the greatest advance in the provision of convenient anticoagulation therapy for many years. A new oral anticoagulation treatment, dabigatran etexilate, is already on the market in Europe. The main interest probably will be to improve the prescription and the adherence to an effective thromboprophylaxis in medical conditions such as atrial fibrillation without bleeding side effects, without the need for monitoring coagulation, and without drug and food interactions such as vitamin K anticoagulant (VKA treatment. Dabigatran is particularly interesting for extended thromboprophylaxis after major orthopedic surgery in order to avoid daily injection for a month. However, oral long-term treatments such as VKA are not systematically associated with a higher compliance level than injected treatments such as low-molecular-weight heparins. Indeed, adherence to an oral treatment, instead of the usual daily injection in major orthopedic surgery, is complex, and based not only on the frequency of dosing but also on patient motivation, understanding, and socio-economic status. New oral anticoagulants may be useful in this way but education and detection of risk factors of nonadherence to treatment are still essential.Keywords: oral anticoagulant, adherence, compliance, education, dabigatran

  14. Understanding noninferiority trials

    Seokyung Hahn

    2012-11-01

    Full Text Available Noninferiority trials test whether a new experimental treatment is not unacceptably less efficacious than an active control treatment already in use. With continuous improvements in health technologies, standard care, and clinical outcomes, the incremental benefits of newly developed treatments may be only marginal over existing treatments. Sometimes assigning patients to a placebo is unethical. In such circumstances, there has been increasing emphasis on the use of noninferiority trial designs. Noninferiority trials are more complex to design, conduct, and interpret than typical superiority trials. This paper reviews the concept of noninferiority trials and discusses some important issues related to them.

    Objectives: to analyze treatment adherence in heart failure (HF) patients followed up by the nursing staff at specialized clinics and its association with patients' characteristics such as number of previous appointments, family structure, and comorbidities. Methods: a cross-sectional study was conducted at two reference clinics for the treatment of HF patients (center 1 and center 2). Data were obtained using a 10-item questionnaire with scores ranging from 0 to 26 points; adherence was considered adequate if the score was ≥ 18 points, or 70% of adherence. Results: a total of 340 patients were included. Mean adherence score was 16 (±4) points. Additionally, 124 (36.5%) patients showed an adherence rate ≥ 70%. It was demonstrated that patients who lived with their family had higher adherence scores, that three or more previous nursing appointments was significantly associated with higher adherence (p<0.001), and that hypertension was associated with low adherence (p=0.023). Conclusions: treatment adherence was considered satisfactory in less than a half of the patients followed up at the two clinics specialized in HF. Living with the family and attending to a great number of nursing appointments improved adherence, while the presence of hypertension led to worse adherence. PMID:26487139

    2016-05-01

    Full Text Available Abstract Background The aim of this study was to analyze whether Cochrane plain language summaries (PLSs adhere to the Standards for the reporting of Plain Language Summaries in new Cochrane Intervention Reviews (PLEACS. Methods A systematic analysis of adherence to the measurable PLEACS items was performed for Cochrane PLSs published from March 2013 to the end of January 2015. Duplicate independent data extraction was performed. An adherence score was calculated for each PLS and for the Cochrane Review Groups (CRGs that published them. Results Of the 1738 analyzed PLSs, not a single one adhered fully to the measured PLEACS items. The highest adherence was found for absence of details of the search strategy (99 % adherence, and the lowest adherence for an item mandating to address quality according to the GRADE system (0.7 % adherence. Overall adherence percentage of PLSs reporting reviews with included studies was 57 %. Different CRGs had a wide range of adherence scores. Conclusions Cochrane plain language summaries are highly heterogeneous with a low adherence to the PLEACS standards. Therefore, there is much room for improving the content and consistency of the PLS. A standardization of PLSs is necessary to ensure delivery of proper and consistent information for consumers.

  19. The development of the ProMAS: a Probabilistic Medication Adherence Scale

    Full Text Available Mieke Kleppe,1,2 Joyca Lacroix,2 Jaap Ham,1 Cees Midden1 1Human Technology Interaction, Eindhoven University of Technology, Eindhoven, the Netherlands; 2Behavior, Cognition and Perception, Philips Research, Eindhoven, the Netherlands Abstract: Current self-report medication adherence measures often provide heavily skewed results with limited variance, suggesting that most participants are highly adherent. This contrasts with findings from objective adherence measures. We argue that one of the main limitations of these self-report measures is the limited range covered by the behaviors assessed. That is, the items do not match the adherence behaviors that people perform, resulting in a ceiling effect. In this paper, we present a new self-reported medication adherence scale based on the Rasch model approach (the ProMAS, which covers a wide range of adherence behaviors. The ProMAS was tested with 370 elderly receiving medication for chronic conditions. The results indicated that the ProMAS provided adherence scores with sufficient fit to the Rasch model. Furthermore, the ProMAS covered a wider range of adherence behaviors compared to the widely used Medication Adherence Report Scale (MARS instrument, resulting in more variance and less skewness in adherence scores. We conclude that the ProMAS is more capable of discriminating between people with different adherence rates than the MARS. Keywords: questionnaire design, probabilistic models, methodology

  20. A systematic review of interventions addressing adherence to anti-diabetic medications in patients with type 2 diabetes--impact on adherence.

    Sujata Sapkota

    Full Text Available The global prevalence of diabetes is increasing. Medications are a recommended strategy to control hyperglycaemia. However, patient adherence can be variable, impacting health outcomes. A range of interventions for patients with type 2 diabetes have focused on improving treatment adherence. This review evaluates the impact of these interventions on adherence to anti-diabetic medications and focuses on the methods and tools used to measure adherence.Medline, Embase, CINAHL, IPA, PUBmed, and PsychINFO were searched for relevant articles published in 2000-2013, using appropriate search terms.Fifty two studies addressing adherence to anti-diabetic medications in patients with type 2 diabetes met the inclusion criteria and were reviewed. Each study was assessed for research design, method(s used for measuring medication adherence, and impact of intervention on medication adherence and glycaemic control. Fourteen studies were published in 2000-2009 and 38 in 2010-2013. Twenty two interventions led to improvements in adherence to anti-diabetic medications, while only nine improved both medication adherence and glycaemic control. A single strategy could not be identified which would be guaranteed to improve anti-diabetic medication adherence consistently. Nonetheless, most interventions were successful in influencing one or more of the outcomes assessed, indicating the usefulness of these interventions under certain circumstances. Self-report, particularly the Summary of Diabetes Self-Care Activities questionnaire was the most commonly used tool to assess medication adherence, although other self-report tools were used in more recent studies. Overall, there was a slight increase in the number of studies that employed multiple methods to assess medication adherence in studies conducted after 2008.The diversity of interventions and adherence measurements prevented a meta-analysis of the impact of interventions on adherence to therapy, highlighting the

    The contribution of bipolar disorder (BD), a prevalent serious mental illness characterized by impulsivity and mood instability, to antiretroviral (ART) and psychiatric medication adherence among HIV-infected (HIV+) individuals is unknown. We examined medication adherence among 44 HIV+/BD+ persons as compared to 33 demographically- and medically-comparable HIV+/BD- persons. Classification of adherent (≥ 90%) or non-adherent (ART adherent (47.7%) as compared to HIV+/BD- (90.9%) persons. Within the HIV+/BD+ group, mean psychiatric medication adherence was significantly worse than ART medication adherence, although there was a significant correlation between ART and psychiatric adherence levels. Importantly, 30-day ART adherence was associated with plasma virologic response among HIV+/BD+ individuals. Given the high overlap of HIV and BD, and the observed medication adherence difficulties for these persons, specialized adherence improvement interventions are needed.

  3. Adherence to antiretroviral therapy of Brazilian HIV-infected children and their caregivers

    Gabriela Ricci

    Full Text Available Abstract Background Successful treatment of HIV-positive children requires a high level of adherence (at least 95% to highly active antiretroviral therapy. Adherence is influenced by factors related to the child and caregivers. Objectives To evaluate children and caregivers characteristics associated to children's adherence. Methods Cross-sectional study, from September 2013 to June 2015, comprising a sample of caregivers of perinatally HIV-infected children, in the age group of 1–12 years, under antiretroviral therapy for at least 6 months and on follow-up in two AIDS reference centers in Salvador, Bahia. Caregiver self-reports were the sole source of 4 days adherence and sociodemographic information. Study participants who reported an intake >95% of prescribed medication were considered adherents. A variable, (“Composed Adherence”, was created to better evaluate adherence. Results We included 77 children and their caregivers. 88.3% of the caregivers were female, the median age was 38.0 years (IQR 33.5–47.5, 48.1% were white or mixed, 72.7% lived in Salvador and 53.2% had no fixed income. The 4 days child's adherence was associated only to caregivers that received less than a minimum salary (p < 0.05, 70.1% of the caregivers had less than four years of formal education, 81.8% were children's relative and 53.2% of the caregivers were HIV positive. The caregiver's pharmacy refill, long-term adherence and 4 days adherence, were significantly associated with composed adherence (p < 0.05. Child's long-term adherence was strongly associated to the 4 days child's adherence referred by caregiver (p < 0.001. Conclusions Our results suggest the need of improvement in HIV-infected children adherence, through reinforcement of the caregivers own adherence.

    Full Text Available Abstract Background Antiretroviral therapy (ART requires high-level (> 95% adherence. Kenya is rolling out ART access programmes and, issue of adherence to therapy is therefore imperative. However, published data on adherence to ART in Kenya is limited. This study assessed adherence to ART and identified factors responsible for non adherence in Nairobi. Methods This is a multiple facility-based cross-sectional study, where 416 patients aged over 18 years were systematically selected and interviewed using a structured questionnaire about their experience taking ART. Additional data was extracted from hospital records. Patients were grouped into adherent and non-adherent based on a composite score derived from a three questions adherence tool developed by Center for Adherence Support Evaluation (CASE. Multivariate regression model was used to determine predictors of non-adherence. Results Overall, 403 patients responded; 35% males and 65% females, 18% were non-adherent, and main (38% reason for missing therapy were being busy and forgetting. Accessing ART in a clinic within walking distance from home (OR = 2.387, CI.95 = 1.155-4.931; p = 0.019 and difficulty with dosing schedule (OR = 2.310, CI.95 = 1.211-4.408, p = 0.011 predicted non-adherence. Conclusions The study found better adherence to HAART in Nairobi compared to previous studies in Kenya. However, this can be improved further by employing fitting strategies to improve patients' ability to fit therapy in own lifestyle and cue-dose training to impact forgetfulness. Further work to determine why patients accessing therapy from ARV clinics within walking distance from their residence did not adhere is recommended.

    Full Text Available Objective: To evaluate adherence to medication and study factors associated with non-adherence in chronic kidney disease (CKD patients. Methods: A prospective, cross-sectional, questionnaire based study was conducted in Nephrology department of a super specialty hospital. Patients above 18 years of age, suffering from CKD from six months or more were interviewed using self-designed, semi-structured questionnaire to get information about adherence to medication, diet restriction and lifestyle modification (n = 150. Morisky medication adherence questionnaire was used to calculate overall adherence. In this higher score indicates poor adherence. Main outcome measures included prevalence of non-adherence and factors associated with the same. Results: Average number of medicines taken by each patient was 8.0+1.612 (mean+SD per day. Non-adherence to medication schedule was reported in 34% patients. Common causes of non-adherence were high cost (21.3%, complex dosing schedule (20%, fear of adverse effects (16%. Sixty-eight% patients were not aware about importance of taking each medicine. Sixteen% stopped taking medicines due to high cost. Forty-two% suggested that government should adopt measures to provide free medicines to poor patients. In Morisky medication adherence questionnaire high, medium and low adherence was reported in 7.3%, 55.3% and 37.3% of patients, respectively. Moderately positive correlation was observed between poor adherence and number of concurrent illnesses and number of medicines taken. Conclusion: Since majority of patients were not aware about importance of taking each medicine, creating awareness about the same is essential for improving adherence to therapy. Measures to provide free medicines to non-affording patients need to be implemented since high cost was other major cause of non-adherence.

Group-based trajectory model (GBTM is an alternative method that overcomes this limitation.Methods: The statistical principles of GBTM and PDC were applied to assess adherence during a 12-month follow-up in psoriasis patients starting treatment with a biologic. The optimal GBTM model was determined on the basis of the balance between each model's Bayesian information criterion and the percentage of patients in the smallest group in each model. Variables potentially predictive of adherence were evaluated.Results: In all, 3,249 patients were included in the analysis. Four GBTM adherence groups were suggested by the optimal model, and patients were categorized as demonstrating continuously high adherence, high-then-low adherence, moderate-then-low adherence, or consistently moderate adherence during follow-up. For comparison, four PDC groups were constructed: PDC Group 4 (PDC ≥75%, PDC Group 3 (25%≤ PDC <50%, PDC Group 2 (PDC <25%, and PDC Group 1 (50%≤ PDC <75%. Our findings suggest that the majority of patients (97.9% from PDC Group 2 demonstrated moderate-then-low adherence, whereas 96.4% of patients from PDC Group 4 showed continuously high adherence. The remaining PDC-based categorizations did not capture patients with uniform adherence behavior based on GBTM. In PDC Group 3, 25.3%, 17.2%, and 57.5% of patients exhibited GBTM-defined consistently moderate adherence, moderate-then-low adherence, or high-then-low adherence, respectively. In PDC Group 1, 70.8%, 23.6%, and 5.7% of patients had consistently moderate adherence, high-then-low adherence, and

  7. Effect of Dietary Exogenous Enzyme Supplementation on Enteric Mucosal Morphological Development and Adherent Mucin Thickness in Turkeys

    2015-10-01

    Full Text Available Anti-nutritional factors in feed ingredients (ANF can challenge gut health and reduce nutrient utilization. Birds typically activate their innate immune system as a protective response against the adverse effects of ANF, which often involves the secretion of mucin. Although dietary supplementation of exogenous enzymes are commonly used to alleviate the adverse effects of ANF on apparent nutrient digestibility, little is known about how they affect gut health, particularly in relation to the morphological development and mucin secretion of enteric mucosa. We carried out two trials to examine the effect of dietary supplementation of different types of exogenous enzymes on gut health of by accessing the effect of jejunum morphological development and ileal enteric adherent mucin thickness layer in turkeys. Dietary β-mannanase supplementation reduced ileal adherent mucin thickness layer (804 µg/g vs 823 µg/g; p<0.05, while a commercial blend of Xylanase, Amylase and Protease (XAP reduced ileal adherent mucin layer thickness (589 µg/g vs 740 µg/g; p<0.05; thus reducing the apparent endogenous loss of nutrients. Both enzyme supplements also affected gut morphological characteristics. In comparison to the control treatment, dietary β-mannanase supplementation improved the jejunum tip width (219 vs 161; p<0.05, base width (367 vs 300; p<0.05, surface area (509,870 vs 380, 157; p<0.05 and villi height/crypt depth ratio (7.49 vs 5.70; p<0.05, and XAP improved the crypt depth (p<0.05. In conclusion dietary supplementation of exogenous enzymes may help alleviate the adverse effects of ANF on nutrient utilization by directly or indirectly removing the mucosal irritation that stimulates enteric mucin secretion.

  8. Adherence to Mediterranean diet is associated with methylation changes in inflammation-related genes in peripheral blood cells.

    Arpón, A; Riezu-Boj, J I; Milagro, F I; Razquin, C; Martínez-González, M A; Corella, D; Estruch, R; Casas, R; Fitó, M; Ros, E; Salas-Salvadó, J; Martínez, J A

    Epigenetic processes, including DNA methylation, might be modulated by environmental factors such as the diet, which in turn have been associated with the onset of several diseases such as obesity or cardiovascular events. Meanwhile, Mediterranean diet (MedDiet) has demonstrated favourable effects on cardiovascular risk, blood pressure, inflammation and other complications related to excessive adiposity. Some of these effects could be mediated by epigenetic modifications. Therefore, the objective of this study was to investigate whether the adherence to MedDiet is associated with changes in the methylation status from peripheral blood cells. A subset of 36 individuals was selected within the Prevención con Dieta Mediterránea (PREDIMED)-Navarra study, a randomised, controlled, parallel trial with three groups of intervention in high cardiovascular risk volunteers, two with a MedDiet and one low-fat control group. Changes in methylation between baseline and 5 years were studied. DNA methylation arrays were analysed by several robust statistical tests and functional classifications. Eight genes related to inflammation and immunocompetence (EEF2, COL18A1, IL4I1, LEPR, PLAGL1, IFRD1, MAPKAPK2, PPARGC1B) were finally selected as changes in their methylation levels correlated with adherence to MedDiet and because they presented sensitivity related to a high variability in methylation changes. Additionally, EEF2 methylation levels positively correlated with concentrations of TNF-α and CRP. This report is apparently the first showing that adherence to MedDiet is associated with the methylation of the reported genes related to inflammation with a potential regulatory impact.

  9. Adherence to treatment after coronary bypass surgery: Psychological aspects

    Maria V. Iakovleva

    2016-01-01

    Full Text Available Poor adherence to treatment is a problem of great importance and striking magnitude. Its consequences are increased health care costs and poor health outcomes. It defined the objective of this research, which is the study of psychological characteristics of patients with different degrees of adherence to rehabilitation treatment after coronary bypass surgery. Ninety male and female patients with CHD, aged 46---71, were examined. The study was carried out using the questionnaire of ways of coping and the technique for diagnosing the types of attitude toward the disease, and the study of medical history. The analysis of the types of attitude toward the disease revealed that adherent patients show higher values on the harmonious type; patients with poor adherence show higher values on the apathetic, as well as the melancholic type of attitude toward illness. This study shows that wide range of psychological characteristics is significant for the definition of adherence to treatment. It is essential to consider the patient’s personality and his characteristics, such as attitude toward the disease, because they influence the adherence and, therefore, the effectiveness of therapy in the postoperative period. La escasa adherencia a la terapia es un problema de gran importancia ampliamente extendido. Sus consecuencias son el aumento de costes del tratamiento y su baja eficacia. El objetivo de la investigación fue el estudio de las características psicológicas de pacientes con diferentes grados de adherencia al tratamiento de rehabilitación después de la cirugía de derivación coronaria. Se recogieron datos clínicos de 90 pacientes de ambos sexos con cardiopatía coronaria, sometidos a cirugía de derivación coronaria, con edades comprendidas entre 46-71 a˜nos. Los cuestionarios administrados fueron el cuestionario de estilos de afrontamiento y la técnica de diagnóstico de tipos de actitud hacia la enfermedad. Además se realizó un estudio

    Full Text Available OBJECTIVE: Aim of this study was the evaluation of the adherence level to GOLD guidelines for the COPD patients’ treatment in the Italian GPs setting, observing the time trend on ICS therapies’ pharmacoutilization, specifically in mild and moderate COPD patients, which is considered inappropriate by GOLD guidelines. Moreover, a pharmacoeconomic analysis has been implemented in order to evaluate the economical burden of the improper management of COPD.METHODS: The retrospective GPs database study has analyzed patients with at least one diagnosis of COPD during the periods January 2005 – December 2008 (Cohort 1 and January 2009 – December 2011 (Cohort 2, who had a reported value of VEMS, at least one prescription of a drug from ATC R03 class within two months from the date of spirometric exam and aged 40 or more. Disease severity has been defined according to 2008 GOLD guidelines. Comparison between the cohorts has been implemented to verify possible variations in guideline adherence. Furthermore, an economical analysis has been developed in order to highlight saves obtained by following GOLD guidelines and the total inappropriate therapies’ costs.RESULTS: The first cohort involved 2,103 COPD patients, while the second cohort included 1,647 subjects. Reduction of ICS therapies has been shown between the two cohorts, with a decrease of 8.4% for mild patient and 1.6% for moderate patients; considering all the disease severities, the reduction was about 4%. Pharmacoeconomic analysis on mild and moderate patients has pointed out that about 50% of the total ICS treatments (814,692 € on 1,658,164 € is related to the ICS element, and so considered inappropriate costs.CONCLUSION: Economic differences between the two periods have highlighted a minor mean costs for Cohort 2, underlining an improvement in the adherence to the GOLD guidelines in the last period.http://dx.doi.org/10.7175/fe.v15i1.887

    Osteoimmunology is the crosstalk between cells from the immune and skeletal systems, suggesting a role of pro-inflammatory cytokines in the stimulation of osteoclast activity. Endotoxin or bacterial challenges to inflammatory cells are directly relevant to dental implant pathologies involving bone resorption, such as osseointegration failure and peri-implantitis. While the endotoxin amount on implant devices is regulated by standards, it is unknown whether commercially available dental implants elicit different levels of adherent-endotoxin stimulated cytokines. The objective of this work is to develop a model system and evaluate endotoxin-induced expression of pro-inflammatory cytokine genes relevant to osteoclast activation on commercially available dental implants. Murine J774-A1 macrophages were cultured on Ti disks with different level of lipopolysaccharide (LPS) contamination to define the time-course of the inflammatory response to endotoxin, as evaluated by reverse transcription polymerase chain reaction analysis. The developed protocol was then used to measure adherent endotoxin on commercially available packaged and sterile dental implants in the "as-implanted" condition. Results show that tested dental implants induce variable expression of endotoxin-stimulated genes, sometimes above the level expected to promote bone resorption in vivo. Results are unaffected by the specific surface treatment; rather, they likely reflect care in cleaning and packaging protocols. In conclusion, expression of genes that enhance osteoclast activity through endotoxin stimulation of inflammatory cells is widely different on commercially available dental implants. A reappraisal of the clinical impact of adherent endotoxins on dental (and bone) implant devices is required in light of increasing knowledge on crosstalk between cells from the immune and skeletal systems.

    Background and objectives Poor growth is a consequence of CKD, but can often be partially or fully prevented or corrected with the use of a number of medications. The extent of nonadherence with medications used to treat or mitigate growth failure in CKD has not been examined prospectively in children with CKD. Design, setting, participants, & measurements The prevalence of both prescription of and nonadherence to recombinant human growth hormone (rhGH), phosphate binders, alkali, active vitamin D, nutritional vitamin D, iron, and erythrocyte-stimulating agents was summarized over the first seven visits of the Chronic Kidney Disease in Children cohort study. The association between self-reported nonadherence to each medication group and the mean annual change in age- and sex-specific height z score was quantified using seven separate linear regression models with generalized estimating equations. Results Of 834 participants, 597 reported use of at least one of these medication groups and had adherence data available. Nonadherence ranged from 4% over all visits for erythrocyte-stimulating agents to 22% over all visits for nutritional vitamin D. Of the study participants, 451 contributed data to at least one of the analyses of adherence and changes in height z score. Children nonadherent to rhGH had no change in height z score, whereas those adherent to rhGH had a significant improvement of 0.16 SDs (95% confidence interval, 0.05 to 0.27); the effect size was slightly larger and remained significant after adjustment. Among participants with height≤3rd percentile and after adjustment, adherence to rhGH was associated with a 0.33 SD (95% confidence interval, 0.10 to 0.56) greater change in height z score. Nonadherence with other medication groups was not significantly associated with a change in height z score. Conclusions Self-reported nonadherence to rhGH was associated with poorer growth velocity in children with CKD, suggesting an opportunity for intervention and

    Full Text Available Abstract Background Sub-optimal adherence to warfarin places millions of patients at risk for stroke and bleeding complications each year. Novel methods are needed to improve adherence for warfarin. We conducted two pilot studies to determine whether a lottery-based daily financial incentive is feasible and improves warfarin adherence and anticoagulation control. Methods Volunteers from the University of Pennsylvania Anticoagulation Management Center who had taken warfarin for at least 3 months participated in either a pilot study with a lottery with a daily expected value of $5 (N = 10 or a daily expected value of $3 (N = 10. All subjects received use of an Informedix Med-eMonitor™ System with a daily reminder feature. If subjects opened up their pill compartments appropriately, they were entered into a daily lottery with a 1 in 5 chance of winning $10 and a 1 in 100 chance of winning $100 (pilot 1 or a 1 in 10 chance of winning $10 and a 1 in 100 chance of winning $100 (pilot 2. The primary study outcome was proportion of incorrect warfarin doses. The secondary outcome was proportion of INR measurements not within therapeutic range. Within-subject pre-post comparisons were done of INR measurements with comparisons with either historic means or within-subject comparisons of incorrect warfarin doses. Results In the first pilot, the percent of out-of-range INRs decreased from 35.0% to 12.2% during the intervention, before increasing to 42% post-intervention. The mean proportion of incorrect pills taken during the intervention was 2.3% incorrect pills, compared with a historic mean of 22% incorrect pill taking in this clinic population. Among the five subjects who also had MEMS cap adherence data from warfarin use in our prior study, mean incorrect pill taking decreased from 26% pre-pilot to 2.8% in the pilot. In the second pilot, the time out of INR range decreased from 65.0% to 40.4%, with the proportion of mean incorrect pill taking dropping

  15. Fetal hemoglobin accumulation in vitro. Effect of adherent mononuclear cells.

    Javid, J; Pettis, P K

    1983-01-01

    In clonal cultures of erythroid burst-forming units (BFU-E) obtained from blood, the accumulation of fetal and adult hemoglobins (Hb F and Hb A) was measured by radioligand immunoassay. Inclusion of adherent mononuclear cells in the culture promoted a striking increase in the relative amount of Hb F in each of 44 experiments with 14 donors. In two-thirds of the instances, this was accounted for by a selective increase in the absolute amount of Hb F. The differential effect on Hb F and Hb A ac...

  17. Which psychosocial factors are related to chelation adherence in thalassemia? A systematic review.

    Evangeli, Michael; Mughal, Kulsoom; Porter, John B

    2010-06-01

    Good adherence to iron chelation therapy in thalassemia is crucial. Although there is evidence that adherence is related to regimen factors, there has been less emphasis on the relationship between psychosocial (psychological, demographic and social) factors and adherence. We present a systematic review of psychosocial correlates of chelation adherence in thalassemia. Nine studies met the inclusion criteria. Information was extracted regarding the study characteristics and the relationship between psychosocial factors and chelation adherence. Methodological quality was rated. The studies took place in a range of countries, were mostly cross sectional in design, and examined adherence to deferoxamine (DFO) only. Sample sizes ranged from 15 to 1573. A variety of psychosocial variables were examined. Definitions of adherence varied between studies and non adherence rates were also variable (9 to 66%). Older age was consistently associated with lower levels of chelation adherence. There were few other consistent findings. The methodological quality of studies was variable. There is a need for more methodologically sophisticated and theoretically informed studies on psychosocial correlates of chelation adherence. We offer specific suggestions.

    Full Text Available Background. The need for a high level of adherence to antiretroviral drugs has remained a major hurdle to achieving maximal benefit from its use in pregnancy. This study was designed to determine the level of adherence and identify factors that influence adherence during pregnancy. Method. This is a cross-sectional study utilizing a semistructured questionnaire. Bivariate and multiple logistic regression models were used to determine factors independently associated with good drug adherence during pregnancy. Result. 137 (80.6% of the interviewed 170 women achieved adherence level of ≥95% using 3 day recall. The desire to protect the unborn child was the greatest motivation (51.8% for good adherence. Fear of being identified as HIV positive (63.6% was the most common reason for nonadherence. Marital status, disclosure of HIV status, good knowledge of ART, and having a treatment supporter were found to be significantly associated with good adherence at bivariate analysis. However, after controlling for confounders, only HIV status disclosure and having a treatment partner retained their association with good adherence. Conclusion. Disclosure of HIV status and having treatment support are associated with good adherence. Maternal desire to protect the child was the greatest motivator for adherence.

    Aim: Treatment non-adherence is a common problem in patients suffering from schizophrenia and depression. This study investigated the possible relationships between symptom severity, quality of sleep, and treatment adherence.Methods: Thirty outpatients with schizophrenia and 58 outpatients with depression were enroled in this study. The beck depression Inventory-II, the positive and negative syndrome scale, and the pittsburgh sleep quality index were used to assess symptom severity and quality of sleep, and sleep log data were used to measure treatment adherence.Results: The preliminary results showed no signiifcant relationship between symptom severity and treatment adherence or between quality of sleep and treatment adherence in patients with depression. However, a signiifcant positive relationship was found between negative symptoms and treatment adherence and a signiifcant negative relationship between quality of sleep and treatment adherence in patients with schizophrenia.Conclusion: The present exploratory study revealed a positive relationship between symptom severity and treatment adherence and a negative relationship between quality of sleep and treatment adherence in patients with schizophrenia, but no signiifcant relationships in patients with depression were found. Future studies are needed in order to gain a better understanding of possible risk factors related to treatment non-adherence.

  20. Adherence to interferon β-1b treatment in patients with multiple sclerosis in Spain.

    Oscar Fernández

    Full Text Available BACKGROUND: Adherence to interferon β-1b (INFβ-1b therapy is essential to maximize the beneficial effects of treatment in multiple sclerosis (MS. For that reason, the main objectives of this study are to assess adherence to INFβ-1b in patients suffering from MS in Spain, and to identify the factors responsible for adherence in routine clinical practice. METHODOLOGY/PRINCIPAL FINDINGS: This was an observational, retrospective, cross-sectional study including 120 Spanish patients with MS under INFβ-1b treatment. Therapeutic adherence was assessed with Morisky-Green test and with the percentage of doses received. The proportion of adherent patients assessed by Morisky-Green test was 68.3%, being indicative of poor adherence. Nevertheless, the percentage of doses received, which was based on the number of injected medication, was 94.3%. The main reason for missing INFβ-1b injections was forgetting some of the administrations (64%. Therefore, interventions that diminish forgetfulness might have a positive effect in the proportion of adherent patients and in the percentage of doses received. In addition, age and comorbidities had a significant effect in the number of doses injected per month, and should be considered in the management of adherence in MS patients. CONCLUSION/SIGNIFICANCE: Among all the available methods for assessing adherence, the overall consumption of the intended dose has to be considered when addressing adherence.
