Antipsychotic prescribing is prevalent in nursing homes for the management of behavioral and psychological symptoms of dementia (BPSD), despite the known risks and limited effectiveness. Many studies have attempted to understand this continuing phenomenon, using qualitative research methods, and have generated varied and sometimes conflicting findings. To date, the totality of this qualitative evidence has not been systematically collated and synthesized. To synthesize the findings from individual qualitative studies on decision-making and prescribing behaviors for antipsychotics in nursing home residents with dementia, with a view to informing intervention development and quality improvement in this field. A systematic review and synthesis of qualitative evidence was conducted (PROSPERO protocol registration CRD42015029141). Six electronic databases were searched systematically from inception through July 2016 and supplemented by citation, reference, and gray literature searching. Studies were included if they used qualitative methods for both data collection and analysis, and explored antipsychotic prescribing in nursing homes for the purpose of managing BPSD. The Critical Appraisal Skills Program assessment tool was used for quality appraisal. A meta-ethnography was conducted to synthesize included studies. The Confidence in the Evidence from Reviews of Qualitative research approach was used to assess the confidence in individual review findings. All stages were conducted by at least 2 independent reviewers. Of 1534 unique records identified, 18 met the inclusion criteria. Five key concepts emerged as influencing decision-making: organizational capacity; individual professional capability; communication and collaboration; attitudes; regulations and guidelines. A "line of argument" was synthesized and a conceptual model constructed, comparing this decision-making process to a dysfunctional negative feedback loop. Our synthesis indicates that when all stakeholders

To evaluate the effectiveness of efforts to translate and disseminate evidence-based guidelines about atypical antipsychotic use to nursing homes (NHs). Three-arm, cluster randomized trial. NHs. NHs in the state of Connecticut. Evidence-based guidelines for atypical antipsychotic prescribing were translated into a toolkit targeting NH stakeholders, and 42 NHs were recruited and randomized to one of three toolkit dissemination strategies: mailed toolkit delivery (minimal intensity); mailed toolkit delivery with quarterly audit and feedback reports about facility-level antipsychotic prescribing (moderate intensity); and in-person toolkit delivery with academic detailing, on-site behavioral management training, and quarterly audit and feedback reports (high intensity). Outcomes were evaluated using the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework. Toolkit awareness of 30% (7/23) of leadership of low-intensity NHs, 54% (19/35) of moderate-intensity NHs, and 82% (18/22) of high-intensity NHs reflected adoption and implementation of the intervention. Highest levels of use and knowledge among direct care staff were reported in high-intensity NHs. Antipsychotic prescribing levels declined during the study period, but there were no statistically significant differences between study arms or from secular trends. RE-AIM indicators suggest some success in disseminating the toolkit and differences in reach, adoption, and implementation according to dissemination strategy but no measurable effect on antipsychotic prescribing trends. Further dissemination to external stakeholders such as psychiatry consultants and hospitals may be needed to influence antipsychotic prescribing for NH residents. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

Physicians face the choice of multiple ingredients when prescribing drugs in many therapeutic categories. For conditions with considerable patient heterogeneity in treatment response, customizing treatment to individual patient needs and preferences may improve outcomes. To assess variation in the diversity of antipsychotic prescribing for mental health conditions, a necessary although not sufficient condition for personalizing treatment. To identify patient caseload, physician, and organizational factors associated with the diversity of antipsychotic prescribing. Using 2011 data from Pennsylvania's Medicaid program, IMS Health's HCOSTM database, and the AMA Masterfile, we identified 764 psychiatrists who prescribed antipsychotics to 10 patients. We constructed three physician-level measures of diversity/concentration of antipsychotic prescribing: number of ingredients prescribed, share of prescriptions for most preferred ingredient, and Herfindahl-Hirschman index (HHI). We used multiple membership linear mixed models to examine patient caseload, physician, and healthcare organizational predictors of physician concentration of antipsychotic prescribing. There was substantial variability in antipsychotic prescribing concentration among psychiatrists, with number of ingredients ranging from 2-17, share for most preferred ingredient from 16%-85%, and HHI from 1,088-7,270. On average, psychiatrist prescribing behavior was relatively diversified; however, 11% of psychiatrists wrote an average of 55% of their prescriptions for their most preferred ingredient. Female prescribers and those with smaller shares of disabled or serious mental illness patients had more concentrated prescribing behavior on average. Antipsychotic prescribing by individual psychiatrists in a large state Medicaid program varied substantially across psychiatrists. Our findings illustrate the importance of understanding physicians' prescribing behavior and indicate that even among specialties

In mental healthcare, one area of major concern identified by health information systems is variability in antipsychotic prescribing. While most studies have investigated patient- and prescriber-related factors as possible reasons for such variability, no studies have investigated facility-level characteristics. The present study ascertained whether staffing level is associated with antipsychotic prescribing in community mental healthcare. A cross-sectional analysis of data extracted from the Italian national mental health information system was carried out. For each Italian region, it collects data on the availability and use of mental health facilities. The rate of individuals exposed to antipsychotic drugs was tested for evidence of association with the rate of mental health staff availability by means of univariate and multivariate analyses. In Italy there were on average nearly 60 mental health professionals per 100,000 inhabitants, with wide regional variations (range 21 to 100). The average rate of individuals prescribed antipsychotic drugs was 2.33%, with wide regional variations (1.04% to 4.01%). Univariate analysis showed that the rate of individuals prescribed antipsychotic drugs was inversely associated with the rate of mental health professionals available in Italian regions (Kendall's tau -0.438, p = 0.006), with lower rates of antipsychotic prescriptions in regions with higher rates of mental health professionals. After adjustment for possible confounders, the total availability of mental health professionals was still inversely associated with the rate of individuals exposed to antipsychotic drugs. The evidence that staffing level was inversely associated with antipsychotic prescribing indicates that any actions aimed at decreasing variability in antipsychotic prescribing need to take into account aspects related to the organization of the mental health system.

The shift from first-generation antipsychotic medications to second-generation antipsychotic medications initially caused a wave of excitement about the potential for improved and broader efficacy of these medications concurrent with an improved side-effect profile. Recent data from high-quality research analyses have subsequently raised significant questions about these claims. This research evidence has, however, not altered prescribing behavior in a way that would be expected from fully rational evaluation of the evidence. Prescribing decisions represent poorly understood, complex behaviors influenced by a number of external and internal forces, some of which may be elucidated by advances in social and cognitive psychology. In this article, the decision to prescribe first- versus second-generation antipsychotic medications is examined, and specific social psychological biases and individual cognitive biases are hypothesized to be significant influences on clinicians. These biases may perpetuate disparity between research evidence and clinical practice.

Dementia can result in cognitive, noncognitive and behavioural symptoms which are difficult to manage. Formal guidelines for the care and management of dementia in the UK state that antipsychotics should only be prescribed where fully justified. This is because inappropriate use, particularly problematic in care-home settings, can produce severe side effects including death. The aim of this study was to explore the use of fallacious arguments in professionals' deliberations about antipsychotic prescribing in dementia in care-home settings. Fallacious arguments have the potential to become unremarkable discourses that construct and validate practices which are counter to guidelines. This qualitative study involved interviews with 28 care-home managers and health professionals involved in caring for patients with dementia. Potentially fallacious arguments were identified using qualitative content analysis and a coding framework constructed from existing explanatory models of fallacious reasoning. Fallacious arguments were identified in a range of explanations and reasons that participants gave for in answer to questions about initiating, reducing doses of and stopping antipsychotics in dementia. The dominant fallacy was false dichotomy. Appeal to popularity, tradition, consequence, emotion, or fear, and the slippery slope argument was also identified. Fallacious arguments were often formulated to present convincing cases whereby prescribing antipsychotics or maintaining existing doses (versus not starting medication or reducing the dose, for example) appeared as the only acceptable decision but this is not always the case. The findings could help health professionals to recognise and mitigate the effect of logic-based errors in decisions about the prescribing of antipsychotics in dementia. © 2016 Royal Pharmaceutical Society.

Methods: It is a prospective cross-sectional study which was carried out for three months from August to November 2015 in the outpatient department of psychiatry. All patients irrespective of their ages and sexes were included in this study. Inpatients, referred patients, patients not willing to give consent, patients of epilepsy as well as those cases where diagnoses were not certain were excluded from the study. The prescription patterns of antipsychotic drugs and the occurrences of various psychiatric diseases on both the sexes were studied after taking permission from the Institutional Ethical Committee (SMCH. Results: A total of 112 prescriptions were analysed. The most common disease was found to be schizophrenia. Total drugs prescribed were 265 and average number of drugs per prescription was 2.36. It was seen that out of the 112 prescriptions, monotherapy was practiced in 19.64% (22 compared to polytherapy in 80.35% (90. Out of 265 prescribed drugs atypical antipsychotics were 112 (42.26%, typical antipsychotics 12 (4.52%, antiepileptics 57 (21.50%, antidepressants 29 (10.94%, antiparkinsonian 29 (10.94%, and others 26 (9.81%.

To examine associations between baseline frailty measures, antipsychotic use, and hospitalization over 1 year and whether hospitalization risk associated with antipsychotic use varies by frailty level. In this prospective cohort study of 1,066 residents (mean age: 85 years; 77% women) from the Alberta Continuing Care Epidemiological Studies, trained research nurses conducted comprehensive resident assessments at baseline (2006-2007) for sociodemographic characteristics, health conditions, frailty status, behavioral problems, and all medications consumed during the past 3 days. Two separate measures of frailty were assessed, the Cardiovascular Health Study (CHS) phenotype and an 86-item Frailty Index (FI). Time to first hospitalization during follow-up was determined via linkage with the Alberta Inpatient Discharge Abstract Database. Baseline frailty status (both measures), but not antipsychotic use, was significantly associated with hospitalization over 1 year. When stratified by frailty, FI-defined frail residents using antipsychotics showed a significantly increased risk for hospitalization (adjusted HR: 1.54; 95% CI: 1.01-2.36) compared with frail nonusers. CHS-defined frail antipsychotic users versus frail nonusers also showed an elevated risk (adjusted HR: 1.67; 95% CI: 0.96-2.88). Nonfrail residents using antipsychotics were significantly less likely to be hospitalized compared with nonfrail nonusers whether defined by the FI (adjusted HR: 0.62; 95% CI: 0.39-0.99) or CHS criteria (adjusted HR: 0.62; 95% CI: 0.40-0.96). Frailty measures may be helpful in identifying those who are particularly vulnerable to adverse effects and those who may experience benefit with treatment.

Regulatory risk communications are an important method for disseminating drug safety information, but their impact varies. Two significant UK risk communications about antipsychotic use in older people with dementia were issued in 2004 and 2009. These varied considerably in their content and dissemination, allowing examination of their differential impact. Segmented regression time-series analysis 2001-2011 for people aged ≥65 years with dementia in 87 Scottish general practices, examining the impact of two pre-specified risk communications in 2004 and 2009 on antipsychotic and other psychotropic prescribing. The percentage of people with dementia prescribed an antipsychotic was 15.9% in quarter 1 2001 and was rising by an estimated 0.6%/quarter before the 2004 risk communication. The 2004 risk communication was sent directly to all prescribers, and specifically recommended review of all patients prescribed relevant drugs. It was associated with an immediate absolute reduction in antipsychotic prescribing of 5.9% (95% CI -6.6 to -5.2) and a change to a stable level of prescribing subsequently. The 2009 risk communication was disseminated in a limited circulation bulletin, and only specifically recommended avoiding initiation if possible. There was no immediate associated impact, but it was associated with a significant decline in prescribing subsequently which appeared driven by a decline in initiation, with the percentage prescribed an antipsychotic falling from 18.4% in Q1 2009 to 13.5% in Q1 2011. There was no widespread substitution of antipsychotics with other psychotropic drugs. The two risk communications were associated with reductions in antipsychotic use, in ways which were compatible with marked differences in their content and dissemination. Further research is needed to ensure that the content and dissemination of regulatory risk communications is optimal, and to track their impact on intended and unintended outcomes.

Capturing service users' perspectives can highlight additional and different concerns to those of clinicians, but there are no up to date, self-report psychometrically sound measures of side effects of antipsychotic medications. Aim To develop a psychometrically sound measure to identify antipsychotic side effects important to service users, the Maudsley Side Effects (MSE) measure. An initial item bank was subjected to a Delphi exercise (n = 9) with psychiatrists and pharmacists, followed by service user focus groups and expert panels (n = 15) to determine item relevance and language. Feasibility and comprehensive psychometric properties were established in two samples (N43 and N50). We investigated whether we could predict the three most important side effects for individuals from their frequency, severity and life impact. MSE is a 53-item measure with good reliability and validity. Poorer mental and physical health, but not psychotic symptoms, was related to side-effect burden. Seventy-nine percent of items were chosen as one of the three most important effects. Severity, impact and distress only predicted 'putting on weight' which was more distressing, more severe and had more life impact in those for whom it was most important. MSE is a self-report questionnaire that identifies reliably the side-effect burden as experienced by patients. Identifying key side effects important to patients can act as a starting point for joint decision making on the type and the dose of medication.

To describe self-reported patterns of prescribing atypical antipsychotics (ATAs) and monitoring practices of child psychiatrists and developmental pediatricians in Canada. We surveyed members of the Canadian Academy of Child and Adolescent Psychiatry and members of the Developmental Paediatrics Section of the Canadian Paediatric Society regarding the types and frequencies of ATAs they prescribed, the ages and diagnoses of patients for whom they prescribed these medications, and the types and frequencies of monitoring used. Ninety-four percent of the child psychiatrists (95% CI, 90% to 97%) and 89% of the developmental pediatricians (95% CI, 75% to 96%) prescribed ATAs, most commonly risperidone (69%). Diagnoses included psychotic, mood, anxiety, externalizing, and pervasive developmental disorders. Prescribing for symptoms such as aggression, low frustration tolerance, and affect dysregulation was also common. Twelve percent of all prescriptions were for children under age 9 years. Most clinicians monitored patients, but there were wide variations in the type and frequency of tests performed. Despite the lack of formal indications, ATAs were prescribed by this group of clinicians for many off-label indications in youth under age 18 years, including very young children. Neither evidence-based guidelines nor a consensus on monitoring exist for this age group.

To determine whether elderly veterans with posttraumatic stress disorder (PTSD) and dementia are more likely to be prescribed second-generation antipsychotics (SGAs) than those with PTSD alone. National serial cross-sectional study. Veterans Health Affairs inpatient and outpatient settings. Veterans aged 65 and older with PTSD (excluding schizophrenia or bipolar disorder) with or without concomitant dementia who received care from the Veterans Health Administration between 2003 and 2010 were identified using International Classification of Diseases, Ninth Revision, codes (N = 93,068; 11.1% with dementia). Trends in SGA prescribing and odds of being prescribed an SGA were determined using a multivariable logistic regression model adjusted for clinical, sociodemographic, and geographic covariates. Between 2004 and 2009, SGA prescribing declined annually from 7.0% to 5.1% of elderly veterans with PTSD without dementia and 13.2% to 8.9% in those with dementia; findings over time consistently indicated that veterans with PTSD and dementia had at least twice the odds of being prescribed an SGA as those without PTSD (odds ratios 2.03 (95% confidence interval (CI) = 1.82-2.26) to 2.33 (95% CI = 2.10-2.58). Although the prescribing of SGAs to elderly veterans with PTSD has decreased, prescribing an SGA to those with dementia remained consistently higher than for those with PTSD alone and is problematic given the high prevalence of medical comorbidities in this aging population coupled with the lack of compelling evidence for effectiveness of SGAs in individuals with dementia. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

To evaluate residents' skills in performing basic mathematical calculations used for prescribing medications to pediatric patients. In 2001, a test of ten questions on basic calculations was given to first-, second-, and third-year residents at Miami Children's Hospital in Florida. Four additional questions were included to obtain the residents' levels of training, specific pediatrics intensive care unit (PICU) experience, and whether or not they routinely double-checked doses and adjusted them for each patient's weight. The test was anonymous and calculators were permitted. The overall score and the score for each resident class were calculated. Twenty-one residents participated. The overall average test score and the mean test score of each resident class was less than 70%. Second-year residents had the highest mean test scores, although there was no significant difference between the classes of residents (p =.745) or relationship between the residents' PICU experiences and their exam scores (p =.766). There was no significant difference between residents' levels of training and whether they double-checked their calculations (p =.633) or considered each patient's weight relative to the dose prescribed (p =.869). Seven residents committed tenfold dosing errors, and one resident committed a 1,000-fold dosing error. Pediatrics residents need to receive additional education in performing the calculations needed to prescribe medications. In addition, residents should be required to demonstrate these necessary mathematical skills before they are allowed to prescribe medications.

The aim was to determine distribution and trends in the outpatient utilization of antipsychotics to evaluate the rationality of antipsychotic drug prescribing during the ten year period. The epidemiological method of descriptive and analytical observation was used. Data on drug utilization from Zagreb Municipal Pharmacy were used to calculate the number of defined daily doses (DDD) and DDD per 1000 inhabitants per day (DDD/TID) using the World Health Organization Anatomical-Therapeutic-Chemical methodology. The ratio of typical versus atypical antipsychotics served as an indicator on assessing the rationality of the utilization. Data on the use of anticholinergics in the treatment of neuroleptic side effects were also included. Outpatient utilization of antipsychotics showed a declining pattern from 14.17 in 2001 to 8.42 DDD/TID in 2010. The utilization of atypical antipsychotics increased by 60% (from 3.68 to 5.89 DDD/TID), while the utilization of typical antipsychotics decreased by 76% (from 10.49 to 2.53 DDD/TID). The drugs showing the largest increase were olanzapine (from 1.21 to 2.78 DDD/TID) and quetiapine (from 0 to 0.68 DDD/TID). The typical/atypical antipsychotic ratio changed from 1:0.4 in 2001 to 1:2.3 in 2010. A 2.3-fold decrease was recorded in the utilization of anticholinergics (from 2.05 to 0.91 DDD/TID). Total consumption of neuroleptics significantly decreased. A decrease was also recorded in the utilization of anticholinergics. Study results pointed to two favorable features, i.e. low use of typical antipsychotics and the ratio of typical and atypical antipsychotics. Implementation of the new clinical guidelines for nervous system disorders and updating of the list of reimbursable drugs with the addition of new ones contributed to the observed improvement in the prescribing patterns during the study period. Using the WHO ATC/DDD methodology and rationality indicators in the assessment of trends in the outpatient utilization of

Several national initiatives aim to teach high-value care to residents. While there is a growing body of literature on cost impact of physicians' therapeutic decisions, few studies have assessed factors that influence residents' prescribing practices. We studied factors associated with intensive health care utilization among internal medicine residents, using brand name statin prescribing as a proxy for higher-cost care. We conducted a retrospective, cross-sectional analysis of statin prescriptions by residents at an urban academic internal medicine program, using electronic health record data between July 1, 2010, and June 30, 2011. For 319 encounters by 90 residents, patients were given a brand name statin in 50% of cases. When categorized into quintiles, the bottom quintile of residents prescribed brand name statins in 2% of encounters, while the top quintile prescribed brand name statins in 98% of encounters. After adjusting for potential confounders, including patient characteristics and supervising attending, being in the primary care track was associated with lower odds (odds ratio [OR], 0.38; P = .02; 95% confidence interval [CI], 0.16-0.86), and graduating from a medical school with an above-average hospital care intensity index was associated with higher odds of prescribing brand name statins (OR, 1.70; P = .049; 95% CI, 1.003-2.88). We found considerable variation in brand name statin prescribing by residents. Medical school attended and residency program type were associated with resident prescribing behavior. Future interventions should raise awareness of these patterns in an effort to teach high-value, cost-conscious care to all residents.

Due to the high rates of inappropriate antibiotic prescribing for presumed urinary tract infections (UTIs) in nursing home (NH) residents, we sought to examine the antibiotic prescribing pathway and the extent to which it agrees with the Loeb criteria; findings can suggest strategies for antibiotic stewardship. Chart review of 260 randomly-selected cases from 247 NH residents treated with an antibiotic for a presumed UTI in 31 NHs in North Carolina. We examined the prescribing pathway from presenting illness, to the prescribing event, illness work-up and subsequent clinical events including emergency department use, hospitalization, and death. Analyses described the decision-making processes and outcomes and compared decisions made with Loeb criteria for initiation of antibiotics. Of 260 cases, 60% had documented signs/symptoms of the presenting illness and 15% met the Loeb criteria. Acute mental status change was the most commonly documented sign/symptom (24%). NH providers (81%) were the most common prescribers and ciprofloxacin (32%) was the most commonly prescribed antibiotic. Fourteen percent of presumed UTI cases included a white blood cell count, 71% included a urinalysis, and 72% had a urine culture. Seventy-five percent of cultures grew at least one organism with ≥100,000 colony-forming units/milliliter and 12% grew multi-drug resistant organisms; 28% of antibiotics were prescribed for more than 7 days, and 7% of cases had a subsequent death, emergency department visit, or hospitalization within 7 days. Non-specific signs/symptoms appeared to influence prescribing more often than urinary tract-specific signs/symptoms. Prescribers rarely stopped antibiotics, and a minority prescribed for overly long periods. Providers may need additional support to guide the decision-making process to reduce antibiotic overuse and antibiotic resistance. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

Investigation of the clinical presentation and treatment of first-episode psychosis is important in order to exclude effects of age, chronic illness, long-term treatment and institutionalization. The aim of this descriptive study was to investigate the management practices of first-episode schizophrenia in a cohort of patients in Israel and to document use of the various "typical" or "atypical" antipsychotic agents. Fifty-one consecutive patients (26 M, 25 F) with first-episode psychosis were recruited for study participation and were administered either typical or atypical antipsychotic medications in a naturalistic manner. While an approximately equal number of subjects received typical and atypical medications at illness onset, a prominent shift to atypical antipsychotic treatment occurred over the study course; 18 subjects had medication class shifts: 17 from typical to atypical, and one from atypical to typical. Negative symptoms did not affect length of hospitalization, but were associated with aggression. Higher depression rates were noted in patients with long hospitalizations who received typical antipsychotic medications. Immigrants were admitted at an age approximately four years older than native-born Israelis. The prominent shift from "typical" to "atypical" antipsychotic medications may indicate sensitivity of first-episode psychotic patients to side-effects of "typical" medications and prominence of use of atypical medications in this patient subpopulation be it due to improved efficacy over time or successful marketing. Unique cultural and population characteristics may contribute to the manifestation of first-episode psychosis and suggest the importance of more effective outreach to the immigrant population in order to manage an apparent treatment delay.

We quantified transdermal fentanyl prescribing in elderly nursing home residents without prior opioid use or persistent pain, and the association of individual and facility traits with opioid-naïve prescribing. Cross-sectional study. Linked Minimum Data Set (MDS) assessments; Online Survey, Certification and Reporting (OSCAR) records; and Medicare Part D claims. From a cross-section of all long-stay US nursing home residents in 2008 with an MDS assessment and Medicare Part D enrollment, we identified individuals (≥65 years old) who initiated transdermal fentanyl, excluding those with Alzheimer disease, severe cognitive impairment, cancer, or receipt of hospice care. We used Medicare Part D to select beneficiaries initiating transdermal fentanyl in 2008 and determined whether they were "opioid-naïve," defined as no opioid dispensing during the previous 60 days. We obtained resident and facility characteristics from MDS and OSCAR records and defined persistent pain as moderate-to-severe, daily pain on consecutive MDS assessments at least 90 days apart. We estimated associations of patient and facility attributes and opioid-naïve fentanyl initiation using multilevel mixed effects logistic regression modeling. Among 17,052 residents initiating transdermal fentanyl, 6190 (36.3%) were opioid-naïve and 15,659 (91.8%) did not have persistent pain. In the regression analysis with adjustments, residents who were older (ages ≥95 odds ratio [OR] 1.69, 95% confidence interval [CI] 1.46-1.95) or more cognitively impaired (moderate-to-severe cognitive impairment, OR 1.99, 95% CI 1.73-2.29) were more likely to initiate transdermal fentanyl without prior opioid use. Most nursing home residents initiating transdermal fentanyl did not have persistent pain and many were opioid-naïve. Changes in prescribing practices may be necessary to ensure Food and Drug Administration warnings are followed, particularly for vulnerable subgroups, such as the cognitively impaired

To assess efficacy and safety of citalopram compared to quetiapine and olanzapine for the treatment of agitation in patients with Alzheimer disease (AD). Longitudinal, 6-month study. Nursing home (NH). 75 NH residents with AD and agitation, randomized to citalopram (n = 25), quetiapine (n = 25), or olanzapine (n = 25). Changes in Neuropsychiatric Inventory (NPI) agitation subscale score and the modified Alzheimer Disease Cooperative Study-Clinical Global Impression of Change (mADCS-CGIC) were used to assess treatment efficacy. Participants were surveilled for adverse health outcomes. Citalopram treatment (30±5.8 mg/d) resulted in similar 6-month efficacy compared to both quetiapine (94.0±40.4 mg/d) and olanzapine (5.2±1.6 mg/d), lower occurrence of falls than olanzapine [odds ratio (OR) = 0.81, 95% confidence interval (CI) = 0.68-0.97, P = .012], lower incidence of orthostatic hypotension than both quetiapine (OR = 0.80, 95% CI = 0.66-0.95, P = .032) and olanzapine (OR = 0.75, 95% CI = 0.69-0.91, P = .02), and less all-cause hospitalizations than both quetiapine (OR = 0.92, 95% CI = 0.88-0.95, P = .016) and olanzapine (OR = 0.78, 95% CI = 0.64-0.92, P = .004), after multiple adjustment for potentially confounding variables. No differences were observed for cognitive and functional decline, QTc prolongation, and infections. Citalopram resulted in similar efficacy and less adverse outcomes when compared to 2 atypical antipsychotics for treatment of agitation in NH residents with AD. Replication of these findings and assessment of long-term efficacy and safety of citalopram for treatment of neuropsychiatric symptoms in dementia are needed.

Community treatment orders (CTOs) are increasingly being used, despite a weak evidence base, and problems continue regarding Second Opinion Appointed Doctor (SOAD) certification of medication. The aim of the current study was to describe current CTO usage regarding patient characteristics, prescribed medication and CTO conditions. A 1-year prospective cohort study with consecutive sampling was conducted for all patients whose CTO was registered in a large mental health trust. Only the first CTO for each patient was included. Measures included sociodemographic variables, psychiatric diagnosis, CTO date of initiation and conditions, psychotropic medication and date of SOAD certification for medication. This study was conducted in the first year of CTO legislation in England and Wales. A total of195 patients were sampled (mean age 40.6 years, 65% male, 52% black ethnic origin). There was significant geographical variability in rates of CTO use (χ(2) = 11.3, p = 0.012). A total of 53% had their place of residence specified as a condition and 29% were required to allow access into their homes. Of those with schizophrenia, 64% were prescribed an antipsychotic long-acting injection (LAI). Of the total group, 7% received high-dose antipsychotics, 10% were prescribed two antipsychotics and only 15% received SOAD certification in time. There was geographical and ethnic variation in CTO use but higher rates of hospital detention in minority ethnic groups may be contributory. Most patients were prescribed antipsychotic LAIs and CTO conditions may not follow the least restrictive principle.
Objective: The newer atypical antipsychotics are prescribed because of their enhanced safety profiles and their larger pharmacological profile in comparison to the conventional antipsychotics. This has led to broad off-label utilisation. The aim of the present survey was to study the prescribing practice of hospital psychiatrists ...

Although it is known that many antipsychotic drugs, at the doses prescribed for schizophrenia, are sedative and cause daytime drowsiness, the effect of potentially diminished vigilance on parenting parameters has not been studied. The aim of this paper is to advise clinicians about sedative load in mothers who are prescribed antipsychotic medication. A Medline search was conducted into the sedative effects of antipsychotics, with the following search terms: sleep; sedation; somnolence; wakefulness; antipsychotics; schizophrenia, parenting, maternal behavior, and custody. The results showed that antipsychotic drugs differ in their propensity to induce sedation and do so via their effects on a variety of neurotransmitter systems. It is important to note that mothers with schizophrenia risk losing custody of their infants if they are perceived as potentially neglectful because of excessive daytime sleepiness. Clinicians must choose antipsychotic medications carefully and monitor for sedative effects whenever the patient has important responsibilities that require the maintenance of vigilance.

Guidelines, policies, and warnings have been applied to reduce the use of medications for behavioral and psychological symptoms of dementia (BPSD). Because of rare dangerous side effects, antipsychotics have been singled out in these efforts. However, antipsychotics are still prescribed "off label" to hundreds of thousands of seniors residing in nursing homes and communities. Our objective was to evaluate how and why primary-care physicians (PCPs) employ nonpharmacologic strategies and drugs for BPSD. Semi-structured interviews analyzed via template, immersion and crystallization, and thematic development of 26 PCPs (16 family practice, 10 general internal medicine) in full time primary-care practice for at least 3 years in Northwestern Virginia. PCPs described 4 major themes regarding BPSD management: (1) nonpharmacologic methods have substantial barriers; (2) medication use is not constrained by those barriers and is perceived as easy, efficacious, reasonably safe, and appropriate; (3) pharmacologic policies decrease the use of targeted medications, including antipsychotics, but also have unintended consequences such as increased use of alternative risky medications; and (4) PCPs need practical evidence-based guidelines for all aspects of BPSD management. PCPs continue to prescribe medications because they meet patient-oriented goals and because PCPs perceive drugs, including antipsychotics and their alternatives, to be more effective and less dangerous than evidence suggests. To optimally treat BPSD, PCPs need supportive verified prescribing guidelines and access to nonpharmacologic modalities that are as affordable, available, and efficacious as drugs; these require and deserve significant additional research and payer support. Community PCPs should be included in BPSD policy and guideline development. © Copyright 2018 by the American Board of Family Medicine.
Comparison of Unlicensed and Off-Label Use of Antipsychotics Prescribed to Child and Adolescent Psychiatric Outpatients for Treatment of Mental and Behavioral Disorders with Different Guidelines: The China Food and Drug Administration Versus the FDA.

This study aims to compare the prevalence of unlicensed and off-label use of antipsychotics among child and adolescent psychiatric outpatients with guidelines proposed by the China Food and Drug Administration (CFDA) and the U.S. Food and Drug Administration (FDA), and to identify factors associated with inconsistencies between the two regulations. A retrospective analysis of 29,326 drug prescriptions for child and adolescent outpatients from the Affiliated Brain Hospital of Guangzhou Medical University was conducted. Antipsychotics were classified as "unlicensed" or "off-label use" according to the latest pediatric license information registered by the CFDA and the FDA or the package inserts of antipsychotics authorized by the CFDA or the FDA for the treatment of pediatric mental and behavioral disorders, respectively. Binary logistic regression analysis was performed to assess factors associated with inconsistencies between the two regulations. The total unlicensed use, according to the CFDA analysis, was higher than that found in the FDA analysis (74.14% vs. 22.04%, p according to the FDA analysis, was higher than that found in the CFDA analysis (46.53% vs. 15.77%, p gender, diagnosis of schizophrenia and schizotypal and delusional disorders, diagnosis of mood [affective] disorders, diagnosis of mental retardation, and diagnosis of psychological development disorders were associated with inconsistent off-label use. The difference in prevalence of total unlicensed and off-label use of antipsychotics between the two regulations was statistically significant. This inconsistency could be partly attributed to differences in pediatric license information and package inserts of antipsychotics. The results indicate a need for further clinical pediatric studies and better harmonization between agencies regarding antipsychotic used in pediatrics.
Full Text Available Background. Classical antipsychotics – neuroleptics are one of the most frequently prescribed psychotropic drugs in child psychiatry. Atypical antipsychotics are used for the same indications – psychotic (schizophrenia as well as unpsychotic disorders (pervasive developmental disorders, mood disorders, conduct disorders and tics disorders. It is surprising that the studies on their use with regard to this age group are rather rare. They are carried out on a small number of samples and only exceptionally double blind. This article summarizes published clinical experience with atypical antipsychotics in children and adolescents. A short overview of pharmacodynamics, pharmacokinetics and side effects is given. Schizophrenia and pervasive developmental disorders are major indications for use of atypical antipsychotics in children and adolescents, but they have also been successfully used for other disorders such as aggressive behaviour, tics and anorexia nervosa.Conclusions. With better side-effect profile, some of the atypical antipsychotics are expected to be doctrinally recognised as the first-line treatment for childhood schizophrenia and pervasive developmental disorders. However, more long-term studies carried out on a larger sample are needed. Atypical antipsychotics are already used in everyday practice as first-line treatment of childhood and adolescents schizophrenia.
Association of the Centers for Medicare & Medicaid Services' National Partnership to Improve Dementia Care With the Use of Antipsychotics and Other Psychotropics in Long-term Care in the United States From 2009 to 2014.

The Centers for Medicare & Medicaid Services' National Partnership to Improve Dementia Care in Nursing Homes (hereafter referred to as the partnership) was established to improve the quality of care for patients with dementia, measured by the rate of antipsychotic prescribing. To determine the association of the partnership with trends in prescribing of antipsychotic and other psychotropic medication among older adults in long-term care. This interrupted time-series analysis of a 20% Medicare sample from January 1, 2009, to December 31, 2014, was conducted among 637 426 fee-for-service Medicare beneficiaries in long-term care with Part D coverage. Data analysis was conducted from May 1, 2017, to January 9, 2018. Quarterly prevalence of use of antipsychotic and nonantipsychotic psychotropic medications (antidepressants, mood stabilizers [eg, valproic acid and carbamazepine], benzodiazepines, and other anxiolytics or sedative-hypnotics). Among the 637 426 individuals in the study (446 538 women and 190 888 men; mean [SD] age at entering nursing home, 79.3 [12.1] years), psychotropic use was declining before initiation of the partnership with the exception of mood stabilizers. In the first quarter of 2009, a total of 31 056 of 145 841 patients (21.3%) were prescribed antipsychotics, which declined at a quarterly rate of -0.53% (95% CI, -0.63% to -0.44%; P care has declined, although the partnership did not accelerate this decrease. However, the use of mood stabilizers, possibly as a substitute for antipsychotics, increased and accelerated after initiation of the partnership in both long-term care residents overall and in those with dementia. Measuring use of antipsychotics alone may be an inadequate proxy for quality of care and may have contributed to a shift in prescribing to alternative medications with a poorer risk-benefit balance.

Previous studies have shown significant ethnic differences in prescribing patterns of two or more antipsychotics. This study examined changes in atypical and typical antipsychotic prescriptions among Asian Americans and Pacific Islanders. Five hundred consecutive charts were reviewed for antipsychotics at the time of admission and discharge from each of two inpatient psychiatric facilities in Hawai'i. Multiple antipsychotic prescription rates were 9% at intake and 6% at discharge. For the ethnic groups studied, there were no statistically significant differences by patient ethnicity regarding antipsychotics at intake (χ(2) = 29.2, df = 21, P = .110) or discharge (χ(2) = 20.5, df = 24, P = .667). There were no significant differences in prescription and polypharmacy patterns among Asian Americans and Pacific Islanders ethnic groups in this study.

Antipsychotic drugs are thought to produce secondary negative symptoms, which can also exacerbate primary negative symptoms. In the present study, we examined whether motivational deficits in particular were related to antipsychotic treatment in patients with schizophrenia in a dose-dependent manner. Five hundred and twenty individuals with schizophrenia who were receiving antipsychotic monotherapy for at least 6 months and followed prospectively were included in the present study. Participants were receiving one of five antipsychotic medications (olanzapine, perphenazine, quetiapine, risperidone, or ziprasidone), and analyses were conducted for patients receiving each drug separately. Analysis of covariance models were constructed to examine the effect of antipsychotic dose on level of motivational impairment, controlling for selected demographic and clinical variables (eg, positive symptoms). Level of motivation, or deficits therein, were evaluated using a derived measure from the Quality of Life Scale, and in addition with scores derived from the Positive and Negative Syndrome Scale. Antipsychotic dose was not related to the level of amotivation for any of the medications examined. Moreover, severity of sedation was not significantly related to the degree of amotivation. One hundred and twenty-one individuals were identified as antipsychotic-free at baseline, and after 6 months of antipsychotic treatment, no change in motivation was found. Chronic treatment with antipsychotics does not necessarily impede or enhance goal-directed motivation in patients with schizophrenia. It is possible that the negative impact of antipsychotics in this regard is overstated; conversely, the present results also indicate that we must look beyond antipsychotics in our efforts to improve motivation.

Prescribing of drugs inhibiting the RAS is common in German nursing homes. Though the prevalence of dual RAS blockade declined, our study showed an increased risk of AKI in patients with diabetes and/or chronic kidney disease. Therefore, cautious use is warranted in these vulnerable patients.

Anecdotal evidence suggests that second-generation antipsychotic agents are increasingly used to treat sleep problems. This study sought to quantify the proportion of new prescriptions for second-generation antipsychotic agents started for sleep/sedation and the correlates of such use. A cross-sectional survey of provider decision making at the time second-generation antipsychotic agents were prescribed, documenting the reasons for the medication, patient demographics, psychiatric and medical diagnoses, patient health characteristics, and provider background. A single Veterans Affairs Medical Center over a 20-month period. Prescribers of second-generation antipsychotic agents. N/A. Seven hundred seven (32.2%) of 2,613 surveys indicated sleep/sedation was at least one reason for using a second-generation anti-psychotic agent, whereas for 266 (12.1%) it was the only reason. Quetiapine was most frequently prescribed overall as well as for sleep/sedation (47.0% and 73.6% respectively). Second-generation antipsychotic agent use for sleep/sedation was unrelated to sociodemographic characteristics, least likely in patients with schizophrenia or bipolar disorder, and most likely as a newly started second-generation antipsychotic agent. Sleep/sedation is a common reason given for new prescriptions of second-generation antipsychotic agents. Quetiapine is most frequently used for this purpose. A greater understanding of why providers use second-generation antipsychotic agents rather than safer and less costly alternatives for sleep problems may advance the development of interventions to reduce adverse effects.

Full Text Available Prolactin provides the growth of the mammary gland during pregnancy and synthesis and preparation of breast milk for lactation. Antipsychotics and antidepressants that are frequently used in psychiatry, cause hyperprolactinemia. The prevalent opinion is that especially typical antipsychotics increase prolactin levels primarily by blocking D2 receptors in the anterior pituitary. The effects of atypical antipsychotics on hyperprolactinemia vary. Hyperprolactinemia causes galactorrhea, gynecomastia, sexual dysfunction, infertility, acne, hirsutism in women, weight gain, obesity and mood changes in addition to menstrual irregularities such as oligomenorrhea, polymenorrhea and amenorrhea. In the long term, hyperprolactinemia may cause reduction in bone density and osteoporosis. Hyperprolactinemia as a side effect of antipsychotics drugs and its treatment will be reviewed in this article. [Psikiyatride Guncel Yaklasimlar - Current Approaches in Psychiatry 2015; 7(2: 109-124

Full Text Available Despite concerns over the potential for severe adverse events, antipsychotic medications remain the mainstay of treatment of behaviour disorders and psychosis in elderly patients. Second-generation antipsychotic agents (SGAs; e.g., risperidone, olanzapine, quetiapine have generally shown a better safety profile compared to the first-generation agents (FGAs; e.g., haloperidol and phenothiazines, particularly in terms of a lower potential for involuntary movement disorders. Risperidone, the only SGA with an official indication for the management of inappropriate behaviour in dementia, has emerged as the antipsychotic most commonly prescribed to older patients. Most clinical trials evaluating the risk of movement disorders in elderly patients receiving antipsychotic therapy have been of limited sample size and/or of relatively short duration. A few observational studies have produced inconsistent results.A population-based retrospective cohort study of all residents of the Canadian province of Manitoba aged 65 and over, who were dispensed antipsychotic medications for the first time during the time period from April 1, 2000 to March 31, 2007, was conducted using Manitoba's Department of Health's administrative databases. Cox proportional hazards models were used to determine the risk of extrapyramidal symptoms (EPS in new users of risperidone compared to new users of FGAs.After controlling for potential confounders (demographics, comorbidity and medication use, risperidone use was associated with a lower risk of EPS compared to FGAs at 30, 60, 90 and 180 days (adjusted hazard ratios [HR] 0.38, 95% CI: 0.22-0.67; 0.45, 95% CI: 0.28-0.73; 0.50, 95% CI: 0.33-0.77; 0.65, 95% CI: 0.45-0.94, respectively. At 360 days, the strength of the association weakened with an adjusted HR of 0.75, 95% CI: 0.54-1.05.In a large population of elderly patients the use of risperidone was associated with a lower risk of EPS compared to FGAs.

Antipsychotic medications are the gold-standard treatment for schizophrenia, and are often prescribed for other mental conditions. However, the efficacy and side-effect profiles of these drugs are heterogeneous, with large interindividual variability. As a result, treatment selection remains a largely trial-and-error process, with many failed treatment regimens endured before finding a tolerable balance between symptom management and side effects. Much of the interindividual variability in response and side effects is due to genetic factors (heritability, h(2)~ 0.60-0.80). Pharmacogenetics is an emerging field that holds the potential to facilitate the selection of the best medication for a particular patient, based on his or her genetic information. In this review we discuss the most promising genetic markers of antipsychotic treatment outcomes, and present current translational research efforts that aim to bring these pharmacogenetic findings to the clinic in the near future.

The purpose of this study was to explore the use of multiple antipsychotic medications in patients with autism spectrum disorder (ASD) by reviewing the longitudinal medication management of 1100 patients consecutively treated for behavioral symptoms associated with ASD at a tertiary care specialty clinic. We identified all patients with ASD treated with daily doses of two or more antipsychotics for at least two visits at our clinic. For each patient meeting inclusion criteria, diagnostic and demographic data were collected. To evaluate clinical need and effectiveness of antipsychotic medications in this sample, we reviewed symptoms targeted with each antipsychotic medication and concomitant medications prescribed. Clinical Global Impressions-Severity (CGI-S) and Clinical Global Impressions-Improvement (CGI-I) scale ratings had been completed at the time of each visit, and the duration of treatment with antipsychotic medications was determined. To evaluate the safety and tolerability of antipsychotic medication use in ASD, we reviewed reported adverse effects and calculated body mass index (BMI) change with treatment. Seventy patients met the inclusion criteria (6.4% of our sample). The majority of patients were moderately to severely ill Caucasian males, as determined by baseline mean CGI-S of 4.7 (SD = 0.8), and were diagnosed with autistic disorder and comorbid intellectual disability. The mean age was 15.1 years (SD = 10.9), the primary targeted symptoms were agitation/irritability, physical aggression, and self-injury. The majority of patients remained on two or more antipsychotics for >1 year. In this population, patients demonstrated greater symptomatic improvement and generally tolerated treatment without significant adverse effects. The use of two or more antipsychotic medications may be increasingly common in patients with ASD. This retrospective study demonstrates that this treatment approach may be of some clinical benefit, and is generally well

Most patients with schizophrenia first start with a single antipsychotic, and yet most finally end up 'switching' or using 'polypharmacy'. The objective of this study was to examine the evolution of antipsychotic switch and polypharmacy in the real-world from a longitudinal perspective. A systematic review of longitudinal antipsychotic prescriptions in 300 patients with schizophrenia (ICD-10) for up to 2 years after their first visit to one of the 4 participating psychiatric clinics in Tokyo, Japan between January, 2007 and June, 2008, was conducted. Reasons for prescription change were also examined. The evolution of switching and polypharmacy was studied, and prescribed doses were compared to suggested dose ranges by the Texas Medication Algorithm Project (TMAP). 208 patients started their antipsychotic treatment with monotherapy. 34.1% of the patients gave up monotherapy with an initial antipsychotic to move to antipsychotic switch (27.4%) and/or polypharmacy (17.8%) within 2 years. The main reason for antipsychotic switch was 'ineffectiveness'; interestingly, this happened despite the fact that the monotherapy dose was below the recommended range in 47.4% of the antipsychotic switch. In a subgroup of 100 patients who started as antipsychotic-free, 2-year prevalence rates of switching and antipsychotic polypharmacy were 27.0% and 18.0%, respectively, and polypharmacy was resorted to after a median of 1 antipsychotic had been tried for 84 days (median). These findings raise a concern that physicians may perform an antipsychotic switch without exploring the entire dose range and resort to antipsychotic polypharmacy without trying an adequate number of antipsychotics.

Atypical antipsychotics are increasingly popular and increasingly prescribed. In some countries, they can even be obtained over-the-counter, without a prescription, making their abuse quite easy. Although atypical antipsychotics are thought to be safer than typical antipsychotics, they still have severe side effects. Intoxications are not rare and some of them have a fatal outcome. Drug interactions involving atypical antipsychotics complicate patient management in clinical settings and the determination of the cause of death in fatalities. In view of the above, analytical strategies that can efficiently isolate atypical antipsychotics from a variety of biological samples and quantify them accurately, sensitively and reliably, are of utmost importance both for the clinical, as well as for the forensic toxicologist. In this review, we will present and discuss novel analytical strategies that have been developed from 2004 to the present day for the determination of atypical antipsychotics in various biological samples.

To assess the long-term effectiveness of antipsychotic medications in facilitating work functioning in patients with schizophrenia we conducted longitudinal multifollowup research on 139 initially psychotic patients. The 70 patients with schizophrenia and 69 initially psychotic mood disordered control patients were followed up 6 times over 20 years. We compared the influence on work functioning of patients with schizophrenia continuously prescribed antipsychotics with patients with schizophrenia not prescribed antipsychotics, using statistical controls for inter-subject differences. While antipsychotics reduce or eliminate flagrant psychosis for most patients with schizophrenia at acute hospitalizations, four years later and continually until the 20 year followups, patients with schizophrenia not prescribed antipsychotics had significantly better work functioning. The work performance of the patients who were continuously prescribed antipsychotics was at a low rate and did not improve over time. Multiple other factors also interfere with work functioning. The data suggest that some patients with schizophrenia not prescribed antipsychotics for prolonged periods can function relatively well. Multiple other factors are associated with poor post-hospital work performance. The longitudinal data raise questions about prolonged treatment of schizophrenia with antipsychotic medications.

As such, elderly patients are commonly prescribed antipsychotic medications for the treatment of psychosis in both acute and chronic conditions. Those conditions include schizophrenia, bipolar disorder, depression and dementia. Elderly patients are at an increased risk of adverse events from antipsychotic medications because of age-related pharmacodynamic and pharmacokinetic changes as well as polypharmacy. Drug selection should be individualized to the patient’s previous history of antipsychotic use, current medical conditions, potential drug interactions, and potential side effects of the antipsychotic. Specifically, metabolic side effects should be closely monitored in this population. This paper provides a review of aripiprazole, a newer second generation antipsychotic agent, for its use in a variety of psychiatric disorders in the elderly including schizophrenia, bipolar disorder, dementia, Parkinson’s disease and depression. We will review the pharmacokinetics and pharmacodynamics of aripiprazole as well as dosing, diagnostic indications, efficacy studies, and tolerability including its metabolic profile. We will also detail patient focused perspectives including quality of life, patient satisfaction and adherence.Keywords: aripiprazole, antipsychotics, elderly, adverse drug reaction

Antipsychotics are effective in treating the symptoms of schizophrenia, but they may induce adverse effects, some of which-those that impact negatively on physical appearance-have not been sufficiently discussed in the psychiatric literature. Through a narrative review, to catalog antipsychotic side effects that interfere with physical attractiveness and to suggest ways of addressing them. PubMed databases were searched for information on the association between "antipsychotic side effects" and "attractiveness" using those two search phrases plus the following terms: "weight," "teeth," "skin," "hair," "eyes," "gait," "voice," "odor." Data from relevant qualitative and quantitative articles were considered, contextualized, and summarized. Antipsychotics, as a group, increase weight and may lead to dry mouth and bad breath, cataracts, hirsutism, acne, and voice changes; they may disturb symmetry of gait and heighten the risk for tics and spasms and incontinence, potentially undermining a person's attractiveness. Clinicians need to be aware of the impact of therapeutic drugs on appearance and how important this issue is to patients. Early in treatment, they need to plan preventive and therapeutic strategies.

To describe the current extent and type of pharmaceutical marketing in nursing homes (NHs) in one state and to provide preliminary evidence for the potential influence of pharmaceutical marketing on the use of atypical antipsychotics in NHs. Nested mixed-methods, cross-sectional study of NHs in a cluster randomized trial. Forty-one NHs in Connecticut. NH administrators, directors of nursing, and medical directors (n = 93, response rate 75.6%). Quantitative data, including prescription drug dispensing data (September 2009-August 2010) linked with Nursing Home Compare data (April 2011), were used to determine facility-level prevalence of atypical antipsychotic use, facility-level characteristics, NH staffing, and NH quality. Qualitative data, including semistructured interviews and surveys of NH leaders conducted in the first quarter of 2011, were used to determine encounters with pharmaceutical marketing. Leadership at 46.3% of NHs (n = 19) reported pharmaceutical marketing encounters, consisting of educational training, written and Internet-based materials, and sponsored training. No association was detected between level of atypical antipsychotic prescribing and reports of any pharmaceutical marketing by at least one NH leader. NH leaders frequently encounter pharmaceutical marketing through a variety of ways, although the impact on atypical antipsychotic prescribing is unclear. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.
Full Text Available Abstract Introduction People with schizophrenia are at increased risk of developing metabolic disturbances. This risk may be further exacerbated by the use of antipsychotic agents. Research is still ongoing to determine the metabolic impact of antipsychotics on glucose regulation. In this case report we review some of the possible mechanisms of action of antipsychotic medication on glucose regulation. Case presentation We present the case of a 50-year-old man diagnosed with paranoid schizophrenia who developed type 2 diabetes mellitus whilst on treatment with second generation antipsychotics (SGA. His diabetes was controlled by a combination of antidiabetic drugs that were associated with his psychotropic treatment. Due to deterioration in his mental state, the patient was admitted on two occasions to a psychiatric unit during which his prescribed medication (olanzapine and risperidone was discontinued and changed to aripiprazole. On both occasions, the patient suffered hypoglycaemic episodes and his antidiabetic treatment had to be adjusted accordingly. The patient did not require any antidiabetic treatment whilst on aripiprazole during the follow up period. Conclusion Clinicians face regular dilemmas in trying to find the right balance between achieving control over a patient's mental illness and reducing any adverse effects associated with the prescribed medication. In patients receiving concomitant antidiabetic therapy, caution should be exercised when changing from one SGA to another. Whilst more longitudinal data are required, a trial of alternative SGAs, including aripiprazole in those developing type 2 diabetes and impaired glucose tolerance may be a worthwhile therapeutic option.

Educational workbooks have been used in psychiatry to influence patient but not clinician behaviour. Targeted education interventions to change prescribing practice in other areas of medicine have only looked at changes in prescribing and not attitudes or beliefs related to the prescribing. We aimed to examine whether clinicians' beliefs about a common prescribing issue in psychiatry (antipsychotic polypharmacy prescription) changed alongside behaviour as a result of a complex intervention. Medical and nursing staff were recruited from 19 general adult psychiatry units in the south-west of the UK as part of a cluster randomized controlled trial. A questionnaire was used to assess beliefs on the prescribing of antipsychotic polypharmacy as a secondary outcome before and after completion of a cognitive behavioural 'self-help' style workbook (one part of a complex intervention). A factor analysis suggested three dimensions of the questionnaire that corresponded to predetermined themes. The data were analysed using a random-effects regression model (adjusting for clustering) controlling for possible confounders. There was a significant change in beliefs on both of the factors: antipsychotic polypharmacy (coefficient = -0.89, P change in antipsychotic polypharmacy prescribing (odds ratio 0.43, 95% confidence intervals 0.21-0.90). The workbook appeared to change staff beliefs about antipsychotic polypharmacy, but achieving substantial changes in clinician behaviour may require further exploration of other factors important in complex prescribing issues.

This study evaluated changes in cardiometabolic monitoring for children and adolescents who were prescribed an antipsychotic medication in a state mental health system before and after a quality improvement intervention. The intervention included education for prescribers, auditing on metabolic monitoring, and feedback to mental health center leaders regarding their monitoring. Research staff extracted yearly data on cardiometabolic monitoring from randomly selected community mental health center records before and after the intervention. Pre- and postintervention changes in monitoring were assessed with chi-squared tests. Evidence of past year monitoring increased: for glucose 18.9%-42.1% (χ 2 = 6.75, p monitoring for blood pressure and waist circumference increased but not significantly. In both years studied, weight was obtained most frequently and waist circumference was obtained least frequently. Monitoring rates significantly improved for four out of six parameters evaluated, but overall monitoring rates remained low at the end of the study period. Prescriber education with audit and feedback may improve cardiometabolic monitoring rates, but research is needed to evaluate barriers to monitoring in children.

Although the Medication Event Monitoring System (MEMS®) device offers accurate information on treatment dosing profile, such profile has never been studied in patients with schizophrenia. Enhancing our knowledge on this issue would help in developing intervention strategies to improve adherence to antipsychotic treatment in these patients. 74 outpatients with schizophrenia were monitored with the MEMS device for a 3-month period, for evaluation of antipsychotic treatment dosing profile, possible influence of medication schedule-related variables, adherence to treatment--considering dose intake within prescribed timeframes--and possible Hawthorne's effect of using the MEMS device. Dose-omission gaps occurred in 18.7% of monitoring days, most frequently during weekends, almost significantly. Almost one-third of prescribed doses were taken out of prescribed time. Neither the prescribed number of daily doses nor the indicated time of the day for dose intake (breakfast, dinner), were associated with correct antipsychotic dosing. Excess-dose was rare in general, and more frequent out of prescribed dose timeframe. No Hawthorne's effect was found for the MEMS device. Adherence reached only 35% according to a definition that included dose intake within prescribed timeframes. Antipsychotic treatment dosing was considerably irregular among patients with schizophrenia. Strategies to reduce dose-omission gaps and increase dosing within prescribed timeframes seem to be necessary. Gaining knowledge on precise oral antipsychotic dosing profiles or the influence of schedule-related variables may be useful to design strategies towards enhancing adherence. There appears to be no Hawthorne's effect associated with the use of MEMS devices in outpatients with schizophrenia. Copyright © 2013 Elsevier B.V. All rights reserved.

Full Text Available The purpose of this study was to identify clinician characteristics associated with higher prescription rates of long-acting injectable (LAI antipsychotics, as well as the sources that influence medical decision-making regarding the treatment of schizophrenia. We surveyed 202 psychiatrists during six regional French conferences (Bordeaux, Lyon, Marseille, Nice, Paris, and Strasbourg. Data on the characteristics of practice, prescription rates of antipsychotic, and information sources about their clinical decisions were collected. Most psychiatrists used second-generation antipsychotics (SGAs, and preferentially an oral formulation, in the treatment of schizophrenia. LAI SGAs were prescribed to 30.4% of schizophrenic patients. The duration and type of practice did not influence the class or formulation of antipsychotics used. The clinicians following the higher percentage of schizophrenic patients were associated with a higher use of LAI antipsychotics and a lower use of oral SGAs. Personal experience, government regulatory approval, and guidelines for the treatment of schizophrenia were the three main contributing factors guiding clinicians’ decision-making regarding the treatment of schizophrenia. The more clinicians follow schizophrenic patients, the more they use LAI antipsychotics. The development of specialized programs with top specialists should lead to better use of LAI antipsychotics in the treatment of schizophrenia.

The medical professions will lose an indispensable tool in clinical practice if even simple infections cannot be cured because antibiotics have lost effectiveness. This article presents results from an exploratory enquiry into “good doctoring” in the case of antibiotic prescribing at a time when...... the knowledge base in the healthcare field is shifting. Drawing on in-depth interviews about diagnosing and prescribing, the article demonstrates how the problem of antimicrobial resistance is understood and engaged with by Danish general practitioners. When general practitioners speak of managing “non......-medical issues,” they refer to routines, clinical expertise, experiences with their patients, and decision-making based more on contextual circumstances than molecular conditions—and on the fact that such conditions can be hard to assess. This article’s contribution to knowledge about how new and global health...

Second-generation antipsychotics vary in their propensity to cause serious cardiometabolic side effects. In addition, use of two or more antipsychotics (polypharmacy) may lead to additive side effects and has not been shown to be consistently more effective than monotherapy. This study examined the use of academic detailing with audit and feedback to improve antipsychotic prescribing practices, including antipsychotic polypharmacy and utilization of medication with high or low risk of cardiometabolic side effects ("high risk" or "low risk," respectively). Four intervention sessions were provided over two years to psychiatric care providers at community mental health centers. Segmented regression within the general estimating equation model framework used Medicaid pharmacy claims to examine prescribing patterns before and after the intervention among all beneficiaries (67,721 person-months) over a five-year period. After the intervention, 10.9% of beneficiaries with antipsychotic claims were on polypharmacy, compared with 13.1% before the invention. Use of high-risk and low-risk antipsychotics did not change. The final adjusted polypharmacy model showed that antipsychotic polypharmacy decreased among young adults and adults ages 40 or older compared with beneficiaries ages 30-39 (β=-.02, p=.04, and β=-.02, p=.007, respectively). The raw proportion of beneficiaries on high- and low-risk agents did not change, although final adjusted models demonstrated changes in use of high- and low-risk agents by diagnosis and risk group. Polypharmacy decreased among young and older adults after academic detailing with audit and feedback. Although further research is needed, this low-intensity intervention may help mental health systems reduce antipsychotic polypharmacy.

Objective: During the past decades, increasing efforts have been invested in studies to unravel the influence of genetic factors on antipsychotic (AP) dosage, treatment response, and occurrence of adverse effects. These studies aimed to improve clinical care by predicting outcome of treatment with APs and thus allowing for individualized treatment strategies. We highlight most important findings obtained through both candidate gene and genome-wide association studies, including pharmacokinetic and pharmacodynamic factors. Methods: We reviewed studies on pharmacogenetics of AP response and adverse effects published on PubMed until early 2012. Owing to the high number of published studies, we focused our review on findings that have been replicated in independent studies or are supported by meta-analyses. Results: Most robust findings were reported for associations between polymorphisms of the cytochrome P450 system, the dopamine and the serotonin transmitter systems, and dosage, treatment response, and adverse effects, such as AP-induced weight gain or tardive dyskinesia. These associations were either detected for specific medications or for classes of APs. Conclusion: First promising and robust results show that pharmacogenetics bear promise for a widespread use in future clinical practice. This will likely be achieved by developing algorithms that will include many genetic variants. However, further investigation is warranted to replicate and validate previous findings, as well as to identify new genetic variants involved in AP response and for replication of existing findings.

Despite sparse documentation of their long-term therapeutic effects and side effects, antipsychotic drugs have come to be prescribed more frequently for children and adolescents in recent years, both in the USA and in Europe. No current data are available about antipsychotic prescriptions for this age group in Germany. Data from the largest statutory health insurance fund in Germany (BARMER GEK) were studied to identify antipsychotic prescriptions for children and adolescents (age 0-19 years) from 2005 to 2012 and analyze them with respect to age, sex, drug prescribed, prescribing medical specialty, and any observable secular trends. The percentage of children and adolescents receiving a prescription for an antipsychotic drug rose from 0.23% in 2005 to 0.32% in 2012. In particular, atypical antipsychotic drugs were prescribed more frequently over time (from 0.10% in 2005 to 0.24% in 2012). The rise in antipsychotic prescriptions was particularly marked among 10- to 14-year-olds (from 0.24% to 0.43%) and among 15- to 19-year-olds (from 0.34% to 0.54%). The prescribing physicians were mostly either child and adolescent psychiatrists or pediatricians; the most commonly prescribed drugs were risperidone and pipamperone. Risperidone was most commonly prescribed for patients with hyperkinetic disorders and conduct disorders. In Germany as in other industrialized countries, antipsychotic drugs have come to be prescribed more frequently for children and adolescents in ecent years. The German figures, while still lower than those from North America, are in the middle range of figures from European countries. The causes of the increase should be critically examined; if appropriate, the introduction of prescribing guidelines of a more restrictive nature could be considered.

Persistent reports have linked atypical antipsychotics with diabetes, yet causative mechanisms responsible for this linkage are unclear. Goals of this review are to outline the pathogenesis of nonimmune diabetes and to survey the available literature related to why antipsychotics may lead to this disease. We accessed the literature regarding atypical antipsychotics and glucose homeostasis using PubMed. The search included English-language publications from 1990 through October 2004. Keywords used included atypical antipsychotics plus one of the following: glucose, insulin, glucose tolerance, obesity, or diabetes. In addition, we culled information from published abstracts from several national and international scientific meetings for the years 2001 through 2004, including the American Diabetes Association, the International Congress on Schizophrenia Research, and the American College of Neuropsychopharmacology. The latter search was necessary because of the paucity of well-controlled prospective studies. We examined publications with significant new data or publications that contributed to the overall comprehension of the impact of atypical antipsychotics on glucose metabolism. We favored original peer-reviewed articles and were less likely to cite single case studies and/or anecdotal information. Approximately 75% of the fewer than 150 identified articles were examined and included in this review. Validity of data was evaluated using the existence of peer-review status as well as our own experience with methodology described in the specific articles. The metabolic profile caused by atypical antipsychotic treatment resembles type 2 diabetes. These agents cause weight gain in treated subjects and may induce obesity in both visceral and subcutaneous depots, as occurs in diabetes. Insulin resistance, usually associated with obesity, occurs to varying degrees with different antipsychotics, although more comparative studies with direct assessment of resistance are

We investigated the association between antipsychotic medications and the risk of dental caries in patients with schizophrenia. We enroled a nationwide cohort of patients with newly diagnosed schizophrenia within 1 year of dental caries development. Exposure to antipsychotics and other medications was categorised according to their type and duration, and the association between exposure and dental caries was assessed through logistic regressions. Of the 3610 patients with newly diagnosed schizophrenia, 2149 (59.5%) exhibited an incidence of treated dental caries. Logistic regression analysis identified a younger age, female sex, high income, a 2-year history of dental caries, and exposure to first-generation antipsychotics, and antihypertensives as independent risk factors for treated dental caries in patients with schizophrenia. Hyposalivation, the adverse effect of first-generation antipsychotics and antihypertensives, was associated with an increased risk of treated dental caries. However, hypersalivation from first-generation antipsychotics for dental caries was associated with a protective factor. These findings suggest that clinicians should pay attention to the aforementioned risk factors for dental caries in patients with schizophrenia, particularly while prescribing first-generation antipsychotics and antihypertensives to such patients.

A substantial proportion of people with mental health conditions do not adhere to prescribed pharmacological treatments. Poor adherence is probably one of the most critical elements contributing to relapse in people with schizophrenia and other severe mental disorders. In order to tackle this global issue, in November 2017 the Food and Drug Administration approved a tablet formulation of the atypical antipsychotic aripiprazole embedded with a novel digital adherence-assessment device. In this commentary, we critically appraised the potential beneficial and harmful consequences of this new digital formulation of aripiprazole, and we highlighted expected implications for clinical practice.

Full Text Available Clinical outcome of patients with severe mental disorders treated with antipsychotics depends on individual response to therapy, adverse events, physical health, maintaining of physical health and of the patient’s, interpersonal (patient - therapist, health and environmental features. Replacement of antipsychotics is a common therapeutic measure. The response depends on mostly unknown genetic factors, physiological particularities of the patient and its variations. This article summarizes the most important and the most recent pharmacological properties and consequences of cross-action of antipsychotics. It specifies the basic rules and ways of replacing antipsychotic drugs in different clinical situations, and summarizes alerts, recommendations and suggestions when changing antipsychotics.

To analyze antipsychotic prescribing patterns in a UK high security hospital (HSH) that treats seriously violent men with either schizophrenia or personality disorder and examine how different groups consented to treatment and prescribing for metabolic conditions. We hypothesized that there would be high prevalence of antipsychotic polypharmacy, and high-dose antipsychotic and clozapine prescribing. HSHs treat seriously violent, mentally disordered offenders, and the extant literature on prescribing patterns in forensic settings is sparse. Prescribing and clinical data on all 189 patients in a UK HSH were collected from the hospital's databases. Data were analyzed using SPSS. The population was split into the following groups: schizophrenia spectrum disorder (SSD-only), personality disorder (PD-only), and comorbid schizophrenia spectrum disorder and PD. The majority (93.7%) of all patients were prescribed at least one antipsychotic, and (27.5%) were on clozapine. Polypharmacy was prevalent in 22.2% and high-dose antipsychotic in 27.5%. Patients on clozapine were more likely to be prescribed antidiabetic, statins, or antihypertensive medication. Patients in the PD-only group were more likely to be deemed to have the capacity to consent to treatment and be prescribed clozapine in contrast to the SSD-only group. Rates of clozapine and high-dose antipsychotic prescribing were higher than in other psychiatric settings, while polypharmacy prescribing rates were lower. Higher clozapine prescribing rates may be a function of a treatment-resistant and aggressive population. A higher proportion of PD-only patients consented to treatment and received clozapine compared with in-house SSD-only as well as other psychiatric settings. Implications of the findings are discussed.

Psychiatric medications such as antidepressants, antipsychotics, and anticonvulsants are commonly prescribed by physicians for the off-label use of improving sleep. Reasons for preferential prescription of these medications over FDA-approved insomnia drugs may include a desire to treat concurrent sleep problems and psychiatric illness with a single medication, and/or an attempt to avoid hypnotic drugs due to their publicized side effects. However, there have been few large studies demonstrating the efficacy and safety of most off-label medications prescribed to treat insomnia. In addition, many of these medications have significant known side effect profiles themselves. Here we review the pertinent research studies published in recent years on antidepressant, antipsychotic, and anticonvulsant medications frequently prescribed for sleep difficulties. Although there have been few large-scale studies for most of these medications, some may be appropriate in the treatment of sleep issues in specific well-defined populations.

In this study, we investigated changes in the expression levels of critical regulatory genes of adipogenesis, lipid metabolism and proinflammatory genes during the differentiation of primary human adipose-derived stem cells (ADSCs). These cells were isolated from patients with body mass indices <25 and treated with the second-generation antipsychotics olanzapine, ziprasidone, clozapine, quetiapine, aripiprazole and risperidone and the first-generation antipsychotic haloperidol. We found that antipsychotics exhibited a marked effect on key genes involved in the regulation of cell cycle, signal transduction, transcription factors, nuclear receptors, differentiation markers and metabolic enzymes. In particular, we observed an induction of the transcription factor NF-KB1 and NF-KB1 target genes in adipocytes in response to these drugs, including the proinflammatory cytokines TNF-α, IL-1β, IL-8 and MCP-1. In addition, enhanced secretion of both IL8 and MCP-1 was observed in the supernatant of these cell cultures. In addition to their remarkable stimulatory effects on proinflammatory gene transcription, three of the most frequently prescribed antipsychotic drugs, clozapine, quetiapine and aripiprazole, also induced the expression of essential adipocyte differentiation genes and the adipocyte hormones leptin

Understanding attitudes toward these medications may help identify barriers and inform personalized therapy. This literature review evaluated patient and clinician attitudes toward the use of antipsychotics for treating bipolar disorder. Materials and methods: A systematic search of the Cochrane Library, Ovid MEDLINE, Embase, and BIOSIS Previews identified English language articles published between January 1, 2000, and June 15, 2016, that reported attitudinal data from patients, health care professionals, or caregivers; treatment decision-making; or patient characteristics that predicted antipsychotic use for bipolar disorder. Results were analyzed descriptively. Results: Of the 209 references identified, 11 met the inclusion criteria and were evaluated. These articles provided attitudinal information from 1,418 patients with bipolar disorder and 1,282 treating clinicians. Patients’ attitudes toward antipsychotics were generally positive. Longer duration of clinical stability was associated with positive attitudes. Implementation of psychoeducational and adherence enhancement strategies could improve patient attitudes. Limited data suggest clinicians’ perceptions of antipsychotic efficacy and tolerability may have the greatest impact on their prescribing patterns. Because the current real-world evidence base is inadequate, clinician attitudes

Full Text Available Abstract Background Since the introduction of antipsychotics, especially the so called atypicals, the treatment of schizophrenia has shown important improvements. At the present time, it is preferred to label clozapine and other antipsychotics sharing similar profiles as second-generation antipsychotics (SGAs. These medications have been proposed by some experts as a first line treatment for schizophrenia. It is critical to have reliable data about antipsychotic prescription in Mexico and to create management guidelines based on expert meetings and not only on studies carried out by the pharmaceutical industry. Only this approach will help to make the right decisions for the treatment of schizophrenia. Methods A translated version of Rabinowitz's survey was used to evaluate antipsychotic prescription preferences and patterns in Mexican psychiatrists. The survey questionnaire was sent by mail to 200 psychiatrists from public institutions and private practice in Mexico City and Guadalajara, Mexico. Results Recommendations for antipsychotics daily doses at different stages of the treatment of schizophrenia varied widely. Haloperidol was considered as the first choice for the treatment of positive symptoms. On the contrary, risperidone was the first option for negative symptoms. For a patient with a high susceptibility for developing extrapyramidal symptoms (EPS, risperidone was the first choice. It was also considered that SGAs had advantages over typical antipsychotics in the management of negative symptoms, cognitive impairment and fewer EPS. Besides, there was a clear tendency for prescribing typical antipsychotics at higher doses than recommended and inadequate doses for the atypical ones. Conclusions Some of the obstacles for the prescription of SGAs include their high cost, deficient knowledge about their indications and dosage, the perception of their being less efficient for the treatment of positive symptoms and the resistance of some

The objective of this study was to analyze the initial treatment with antipsychotics (APs) and its changes during the first year of treatment in patients visited in specialized child and adolescent psychiatry departments. Participants were 265 patients, aged 4 to 17 years, who attended consecutively at 4 different centers and were naive of AP or quasi-naive (less than 30 days since the beginning of AP treatment). Type of AP, dosage, and concomitant medication were registered at baseline, 1, 3, 6, and 12 months after beginning the treatment with AP. At baseline, the patients' mean age was 14.4 (2.9) years, and 145 (54.7%) patients were males. Antipsychotics were more prescribed in the following: schizophrenia spectrum disorders (30.2%), disruptive behavior disorders (DBDs) (18.9%), bipolar disorders (14.3%), depressive disorders (12.8%), and eating disorders (11.7%). A total of 93.2% of the patients were on an off-label indication of AP. Risperidone was the AP most prescribed in all the assessments, but differences were observed in the type of AP according to diagnosis. Thus, risperidone was significantly most prescribed in patients with DBD and olanzapine was most prescribed in patients with eating disorders. Olanzapine and quetiapine were the second-generation APs (SGAs) most prescribed after risperidone, and haloperidol was the most prescribed first-generation AP. Up to 8.3% of patients during the follow-up were on AP polypharmacy. Almost 16% patients had a change in its AP treatment during the follow-up, and the main switch was from one SGA to another. Second-generation APs were the APs most prescribed in our sample and approximately 93% of the patients used AP off-label. Risperidone was the most common AP used above all in patients with DBD, whereas olanzapine was most prescribed in patients with eating disorders. Antipsychotic polypharmacy and switch rates were low during the follow-up.

Medicaid quality indicators track diabetes mellitus and cardiovascular disease screening in adults receiving antipsychotics and/or those with serious mental illness. To inform performance improvement interventions by evaluating the relative importance of patient, prescriber, and practice factors affecting metabolic testing. A retrospective cohort study was conducted using Missouri Medicaid administrative claims data (January 1, 2010, to December 31, 2012) linked with prescriber market data. The analysis included 9316 adults (age, 18-64 years) who were starting antipsychotic medication. Secondary analysis included the subset of adults (n = 1813) for whom prescriber knowledge, attitudes, and behavior survey data were available. Generalized estimating equations were performed to identify factors associated with failure to receive annual testing during antipsychotic treatment (adjusted odds ratio [OR], 6 encounters vs none; 0.33 [0.28-0.39]). Analysis incorporating prescriber practice information found lower failure to receive glucose testing if the patient received care at a CMHC (0.74 [0.64-0.85]) or if the initiating prescriber was a primary care practitioner (0.81 [0.66-1.00]). However, the initiating prescriber specialty-setting was not associated with lipid testing. Compared with prior reports, progress has been made to improve diabetes screening, but lipid screening remains particularly underutilized. Medicaid performance improvement initiatives should target all prescriber settings and not just behavioral health.

Novel antipsychotic agents differ from conventional ones in several key characteristics, including effectiveness, adverse reactions, and receptor-binding profile. Most of the newer agents have an affinity for the serotonin 5HT2 receptor that is at least 10 times greater than that for the dopamine D2 receptor. This increased affinity for the serotonin receptor may be responsible for another distinguishing characteristic of novel antipsychotic agents--decreased frequency of extrapyramidal side effects. These side effects, which include pseudoparkinsonism, acute dystonias, and akathisia, frequently are the reason for noncompliance with conventional drug therapy. The newer drugs are often effective in patients resistant to treatment with conventional agents. They also appear to reduce the negative symptoms of schizophrenia in many patients.

Antipsychotics have long been the mainstay of treatment for agitation and psychosis in Alzheimer's disease. Despite their current use successive studies have shown that they only confer a modest benefit which must be balanced against their well-established serious side effects (extrapyramidal symptoms, stroke, accelerated cognitive decline and mortality). Areas covered: This review outlines the current guidance on antipsychotic usage and the evidence of their continued usage against a backdrop of emerging pharmacological treatments and an increasing emphasis on the importance of non-pharmacological interventions. Expert commentary: The current justification for antipsychotic use in the context of the changing landscape of prescribing and provide a view on the most promising alternative candidates to this class of drug are appraised.

This survey aimed to understand the attitude of psychiatrists and their use of commonly prescribed second-generation antipsychotics (SGAs) for the treatment of schizophrenia in Taiwan. It also attempted to identify the factors that might influence their preference for selecting SGAs. Psychiatrists were interviewed face-to-face using a structured questionnaire. The questionnaire addressed various issues involved in the treatment of patients with schizophrenia, including the reasons for selecting SGAs, psychiatrists' level of satisfaction with commonly prescribed SGAs, and their current use of SGAs in clinical practice. Gender and age of the psychiatrists, and practice setting were not related to SGA selection. The selection of a SGA might be influenced by characteristics of the psychiatrist, properties of the drugs, and the healthcare insurance system. Most psychiatrists agreed that the performance of brand-name drugs was superior to that of generic drugs. Better symptom control, improvement in cognition, and higher tolerability were among the major factors considered by psychiatrists in Taiwan when prescribing antipsychotics. Selection of a SGA in Taiwan is potentially influenced by the characteristics of the psychiatrist, properties of the drug, and the healthcare insurance system. Efficacy and tolerability were among the major determining factors when prescribing antipsychotics for the treatment of patients with schizophrenia.

Antipsychotic drugs are used increasingly by children and adolescents and there is concern about off-label use. We aimed to study which substances, and for which mental disorder diagnoses, antipsychotic drugs were prescribed to 0-18-year-old boys and girls in Norway. Linked data from the national health registry for prescription drugs in 2010 and mental disorder diagnoses in 2008-2012 were used to study the prevalence of antipsychotic drug use, the type of antipsychotic drug substances used, mental disorder diagnoses in users and distribution of drugs per diagnostic category across gender. In total, 0.18% of Norwegian children and adolescents were prescribed antipsychotic drugs during 2010, of which there were more boys (0.23%) than girls (0.13%). Risperidone was the most frequently used substance among boys (57.4%) and girls (32.3%), followed by aripiprazole (19.4%) in boys and quetiapine (27.4%) in girls. The most common mental disorder diagnoses among male users were hyperkinetic (49.9%) and autism spectrum disorder (27.1%), while anxiety disorders (41.5%) and depressive illness (33.6%) were most common among female users. A schizophrenia-like psychosis diagnosis was given to 11.1% of the male and 18.2% of the female users. A hyperkinetic disorder was diagnosed among 56.9% and 52.4% of the male risperidone and aripiprazole users, respectively. Among female quetiapine users, 57.1% were diagnosed with anxiety disorders and 52.4% with depressive illness. These results demonstrate that children and adolescents who use antipsychotic drugs are predominantly diagnosed with non-psychotic mental disorders such as hyperkinetic disorder among boys and anxiety disorder or depressive illness among girls.

Full Text Available Madhubhashinee Dayabandara, Raveen Hanwella, Suhashini Ratnatunga, Sudarshi Seneviratne, Chathurie Suraweera, Varuni A de Silva Department of Psychiatry, Faculty of Medicine, University of Colombo, Colombo, Sri Lanka Abstract: Antipsychotic-induced weight gain is a major management problem for clinicians. It has been shown that weight gain and obesity lead to increased cardiovascular and cerebrovascular morbidity and mortality, reduced quality of life and poor drug compliance. This narrative review discusses the propensity of various antipsychotics to cause weight gain, the pharmacologic and nonpharmacologic interventions available to counteract this effect and its impact on adherence. Most antipsychotics cause weight gain. The risk appears to be highest with olanzapine and clozapine. Weight increases rapidly in the initial period after starting antipsychotics. Patients continue to gain weight in the long term. Children appear to be particularly vulnerable to antipsychotic-induced weight gain. Tailoring antipsychotics according to the needs of the individual and close monitoring of weight and other metabolic parameters are the best preventive strategies at the outset. Switching to an agent with lesser tendency to cause weight gain is an option, but carries the risk of relapse of the illness. Nonpharmacologic interventions of dietary counseling, exercise programs and cognitive and behavioral strategies appear to be equally effective in individual and group therapy formats. Both nonpharmacologic prevention and intervention strategies have shown modest effects on weight. Multiple compounds have been investigated as add-on medications to cause weight loss. Metformin has the best evidence in this respect. Burden of side effects needs to be considered when prescribing weight loss medications. There is no strong evidence to recommend routine prescription of add-on medication for weight reduction. Heterogeneity of study methodologies and other
Full Text Available Abstract Background Several clinical studies suggested that antipsychotic-based medications could ameliorate cognitive functions impaired in certain schizophrenic patients. Accordingly, we investigated the effects of various dopaminergic receptor antagonists – including atypical antipsychotics that are prescribed for the treatment of schizophrenia – in a model of toxicity using cultured hippocampal neurons, the hippocampus being a region of particular relevance to cognition. Results Hippocampal cell death induced by deprivation of growth medium constituents was strongly blocked by drugs including antipsychotics (10-10-10-6 M that display nM affinities for D2 and/or D4 receptors (clozapine, haloperidol, (±-sulpiride, domperidone, clozapine, risperidone, chlorpromazine, (+-butaclamol and L-741,742. These effects were shared by some caspases inhibitors and were not accompanied by inhibition of reactive oxygen species. In contrast, (--raclopride and remoxipride, two drugs that preferentially bind D2 over D4 receptors were ineffective, as well as the selective D3 receptor antagonist U 99194. Interestingly, (--raclopride (10-6 M was able to block the neuroprotective effect of the atypical antipsychotic clozapine (10-6 M. Conclusion Taken together, these data suggest that D2-like receptors, particularly the D4 subtype, mediate the neuroprotective effects of antipsychotic drugs possibly through a ROS-independent, caspase-dependent mechanism.

The aim of this study was to use routinely collected electronic medicines administration (eMAR) data in residential aged care (RAC) to investigate the quality use of medicines. A cross-sectional analysis of eMAR data. 71 RAC facilities in New South Wales and the Australian Capital Territory, Australia. Permanent residents living in a participating facility on 1 October 2015. None. Variation in polypharmacy (≥5 medications), hyper-polypharmacy (≥10 medications) and antipsychotic use across facilities was examined using funnel plot analysis. The study dataset included 4775 long-term residents. The mean resident age was 85.3 years and 70.6% of residents were female. The median facility size was 60 residents and 74.3% were in metropolitan locations. 84.3% of residents had polypharmacy, 41.2% hyper-polypharmacy and 21.0% were using an antipsychotic. The extent of polypharmacy (69.75-100% of residents), hyper-polypharmacy (38.81-76.19%) and use of antipsychotic medicines (0-75.6%) varied considerably across the 71 facilities. Using eMAR data we found substantial variation in polypharmacy, hyper-polypharmacy and antipsychotic medicine use across 71 RAC facilities. Further investigation into the policies and practices of facilities performing above or below expected levels is warranted to understand variation and drive quality improvement.

To measure the incidence of movement side effects of antipsychotic drugs in adults with intellectual disability and compare rates with adults without intellectual disability. Cohort study using data from The Health Improvement Network. UK primary care. Adults with intellectual disability prescribed antipsychotic drugs matched to a control group of adults without intellectual disability prescribed antipsychotic drugs. New records of movement side effect including acute dystonias, akathisia, parkinsonism, tardive dyskinaesia and neuroleptic malignant syndrome. 9013 adults with intellectual disability and a control cohort of 34 242 adults without intellectual disability together contributed 148 709 person-years data. The overall incidence of recorded movement side effects was 275 per 10 000 person-years (95% CI 256 to 296) in the intellectual disability group and 248 per 10 000 person-years (95% CI 237 to 260) in the control group. The incidence of any recorded movement side effect was significantly greater in people with intellectual disability compared with those without (incidence rate ratio 1.30, 95% CI 1.18 to 1.42, pmovement side effects between the groups were not due to differences in the proportions prescribed first and second-generation antipsychotic drugs. This study provides evidence to substantiate the long-held assumption that people with intellectual disability are more susceptible to movement side effects of antipsychotic drugs. Assessment for movement side effects should be integral to antipsychotic drug monitoring in people with intellectual disability. Regular medication review is essential to ensure optimal prescribing in this group. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

BACKGROUND AND OBJECTIVE: Drug therapy is necessary to treat acute illness, maintain current health and prevent further decline. However, optimizing drug therapy for older patients is challenging and sometimes, drug therapy can do more harm than good. Drug utilization review tools can highlight instances of potentially inappropriate prescribing to those involved in elderly pharmacotherapy, i.e. doctors, nurses and pharmacists. We aim to provide a review of the literature on potentially inappropriate prescribing in the elderly and also to review the explicit criteria that have been designed to detect potentially inappropriate prescribing in the elderly. METHODS: We performed an electronic search of the PUBMED database for articles published between 1991 and 2006 and a manual search through major journals for articles referenced in those located through PUBMED. Search terms were elderly, inappropriate prescribing, prescriptions, prevalence, Beers criteria, health outcomes and Europe. RESULTS AND DISCUSSION: Prescription of potentially inappropriate medications to older people is highly prevalent in the United States and Europe, ranging from 12% in community-dwelling elderly to 40% in nursing home residents. Inappropriate prescribing is associated with adverse drug events. Limited data exists on health outcomes from use of inappropriate medications. There are no prospective randomized controlled studies that test the tangible clinical benefit to patients of using drug utilization review tools. Existing drug utilization review tools have been designed on the basis of North American and Canadian drug formularies and may not be appropriate for use in European countries because of the differences in national drug formularies and prescribing attitudes. CONCLUSION: Given the high prevalence of inappropriate prescribing despite the widespread use of drug-utilization review tools, prospective randomized controlled trials are necessary to identify useful interventions.

Despite national concerns over high rates of antipsychotic medication use among youth in foster care, concomitant antipsychotic use has not been examined. In this study, concomitant antipsychotic use among Medicaid-enrolled youth in foster care was compared with disabled or low-income Medicaid-enrolled youth. The sample included 16 969 youths younger than 20 years who were continuously enrolled in a Mid-Atlantic state Medicaid program and had ≥1 claim with a psychiatric diagnosis and ≥1 antipsychotic claim in 2003. Antipsychotic treatment was characterized by days of any use and concomitant use with ≥2 overlapping antipsychotics for >30 days. Medicaid program categories were foster care, disabled (Supplemental Security Income), and Temporary Assistance for Needy Families (TANF). Multicategory involvement for youths in foster care was classified as foster care/Supplemental Security Income, foster care/TANF, and foster care/adoption. We used multivariate analyses, adjusting for demographics, psychiatric comorbidities, and other psychotropic use, to assess associations between Medicaid program category and concomitant antipsychotic use. Average antipsychotic use ranged from 222 ± 110 days in foster care to only 135 ± 101 days in TANF (P foster care only and 24% in foster care/adoption compared with youths in the foster care system.
Full Text Available Schizophrenia is a severe psychiatric disorder often associated with cognitive impairment and affective, mainly depressive, symptoms. Antipsychotic medication is the primary intervention for stabilization of acute psychotic episodes and prevention of recurrences and relapses in patients with schizophrenia. Typical antipsychotics, the older class of antipsychotic agents, are currently used much less frequently than newer atypical antipsychotics. Therapeutic drug monitoring (TDM of antipsychotic drugs is the specific method of clinical pharmacology, which involves measurement of drug serum concentrations followed by interpretation and good cooperation with the clinician. TDM is a powerful tool that allows tailor-made treatment for the specific needs of individual patients. It can help in monitoring adherence, dose adjustment, minimizing the risk of toxicity and in cost-effectiveness in the treatment of psychiatric disorders. The review provides complex knowledge indispensable to clinical pharmacologists, pharmacists and clinicians for interpretation of TDM results.

in the range of 1.3- to 2-fold greater. Preliminary data also indicate that the highest risk of stroke is related to the first weeks of treatment, and a risk profile for stroke is emerging, such as older age, cognitive impairment and vascular illness. Different pathophysiological pathways may be involved, ranging from the facilitation of thrombosis, pre-existing cardiovascular factors, sedation and a common diathesis for stroke of dementia, schizophrenia and affective illness. Before prescribing an antipsychotic, clinicians should weigh all the risk factors for a given patient and consider not only the indications as provided by the regulatory agencies, but also the overall effectiveness of typical and atypical antipsychotics.

This study compares inter- and intra-country differences in the prevalence of physical restraints and antipsychotic medications in nursing homes, and examines aggregated resident conditions and organizational characteristics correlated with these treatments. Population-based, cross-sectional data were collected using a standardized Resident Assessment Instrument (RAI) from 14,504 long-term care facilities providing nursing home level services in five countries participating in the interRAI consortium, including Canada, Finland, Hong Kong (Special Administrative Region, China), Switzerland, and the United States. Facility-level prevalence rates of physical restraints and antipsychotic use were examined both between and within the study countries. The prevalence of physical restraint use varied more than five-fold across the study countries, from an average 6% in Switzerland, 9% in the US, 20% in Hong Kong, 28% in Finland, and over 31% in Canada. The prevalence of antipsychotic use ranged from 11% in Hong Kong, between 26-27% in Canada and the US, 34% in Switzerland, and nearly 38% in Finland. Within each country, substantial variations existed across facilities in both physical restraint and antipsychotic use rates. In all countries, neither facility case mix nor organizational characteristics were particularly predictive of the prevalence of either treatment. There exists large, unexplained variability in the prevalence of physical restraint and antipsychotic use in nursing home facilities both between and within countries. Since restraints and antipsychotics are associated with adverse outcomes, it is important to understand the idiosyncratic factors specific to each country that contribute to variation in use rates.

Licensed indications for medicines were designed to regulate the claims that can be made about a medicine by a pharmaceutical company. Off-label prescribing (i.e. prescribing a drug for an indication outside of that for which it is licensed) is legal and an integral part of medical practice. In psychiatry, off-label prescribing is common and gives clinicians scope to treat patients who are refractory to standard therapy or where there is no licensed medication for an indication. However, efficacy or safety of such off-label use may not be established. There is a growing list of licensed indications for atypical antipsychotics (AAP) beyond schizophrenia and bipolar affective disorder, and also more evidence for other indications where pharmaceutical companies have not obtained a license. Pharmaceutical companies have promoted AAPs for off-label indications to increase sales and consequently have been fined by the US FDA for this. Since the 1990s, AAP use has expanded considerably, for example, the off-label use of quetiapine alone accounted for an estimated 17% of the AAP spend in New Zealand in 2010. There are a number of potential problems with the expanded use of AAPs outside of schizophrenia and related psychoses. A larger population will be exposed to their adverse effects, which include weight gain, type 2 diabetes mellitus, sudden cardiac death and increased mortality rates in the elderly with dementia. There are also concerns with the abuse of these agents, in particular quetiapine. Given that an increasing percentage of the population is being treated with these agents, off-label prescribing of AAPs is a cause for concern; they have a propensity to cause significant side effects and their efficacy and long-term safety for most off-label indications remains largely unknown, and therefore the risks and benefits of their use should be carefully weighed up prior to prescribing these agents off-label.

Schizophrenia requires lifelong treatment, potentially causing systemic changes in metabolic homeostasis. In the clinical setting, antipsychotic treatment may differentially lead to weight gain among individual patients, although the molecular determinants of such adverse effects are currently unknown. In this study, we investigated changes in the expression levels of critical regulatory genes of adipogenesis, lipid metabolism and proinflammatory genes during the differentiation of primary human adipose-derived stem cells (ADSCs). These cells were isolated from patients with body mass indices <25 and treated with the second-generation antipsychotics olanzapine, ziprasidone, clozapine, quetiapine, aripiprazole and risperidone and the first-generation antipsychotic haloperidol. We found that antipsychotics exhibited a marked effect on key genes involved in the regulation of cell cycle, signal transduction, transcription factors, nuclear receptors, differentiation markers and metabolic enzymes. In particular, we observed an induction of the transcription factor NF-KB1 and NF-KB1 target genes in adipocytes in response to these drugs, including the proinflammatory cytokines TNF-α, IL-1β, IL-8 and MCP-1. In addition, enhanced secretion of both IL8 and MCP-1 was observed in the supernatant of these cell cultures. In addition to their remarkable stimulatory effects on proinflammatory gene transcription, three of the most frequently prescribed antipsychotic drugs, clozapine, quetiapine and aripiprazole, also induced the expression of essential adipocyte differentiation genes and the adipocyte hormones leptin and adiponectin, suggesting that both glucose and fat metabolism may be affected by these drugs. These data further suggest that antipsychotic treatments in patients alter the gene expression patterns in adipocytes in a coordinated fashion and priming them for a low-level inflammatory state.

Full Text Available The purpose of this study is to examine the use of prescribed psychoactive medications in a prospective cohort of children shortly after they entered foster homes; and to identify demographics, maltreatment history, psychiatric diagnoses including ADHD comorbidity, and level of aggression that contribute to prescribed use of stimulant and atypical antipsychotic medication over time.The sample included N = 252 children (nested in 95 sibling groups followed for three years up to 4 yearly waves.Nearly all (89% met criteria for at least one of eight psychiatric diagnoses and 31% (75/252 used one or more prescribed psychoactive medications. Over half (55% were diagnosed with Attention Deficit Hyperactivity Disorder (ADHD; of these 38% used stimulants and 36% used atypical antipsychotics.

The emergence of electronic prescribing devices with clinical decision support systems (CDSS) is able to significantly improve management pharmacological treatments. We developed a web application available on smartphones in order to help clinicians monitor prescription and further propose CDSS. A web application (www.MEmind.net) was developed to assess patients and collect data regarding gender, age, diagnosis and treatment. We analyzed antipsychotic prescriptions in 4345 patients attended in five Psychiatric Community Mental Health Centers from June 2014 to October 2014. The web-application reported average daily dose prescribed for antipsychotics, prescribed daily dose (PDD), and the PDD to defined daily dose (DDD) ratio. The MEmind web-application reported that antipsychotics were used in 1116 patients out of the total sample, mostly in 486 (44%) patients with schizophrenia related disorders but also in other diagnoses. Second generation antipsychotics (quetiapine, aripiprazole and long-acting paliperidone) were preferably employed. Low doses were more frequently used than high doses. Long acting paliperidone and ziprasidone however, were the only two antipsychotics used at excessive dosing. Antipsychotic polypharmacy was used in 287 (26%) patients with classic depot drugs, clotiapine, amisulpride and clozapine. In this study we describe the first step of the development of a web application that is able to make polypharmacy, high dose usage and off label usage of antipsychotics visible to clinicians. Current development of the MEmind web application may help to improve prescription security via momentary feedback of prescription and clinical decision support system.

Nursing home quality measures include the proportion of residents who receive antipsychotics. Residents with bipolar disorder are included even though antipsychotics are FDA-approved for this indication. We evaluated how including residents with bipolar disorder impacted the antipsychotic use quality measure for long-stay residents. We evaluated the agreement of minimum data set (MDS) bipolar disorder diagnoses with Medicare data, whether dementia was diagnosed before bipolar disorder, and how less-specific bipolar disorder diagnoses impacted findings. Cross-sectional study. Nursing homes in Iowa. 21,955 long-stay nursing home residents in the first quarter of 2014. We identified antipsychotic use and bipolar disorder using MDS data. We compared MDS bipolar disorder diagnoses with Chronic Conditions Warehouse (CCW) "ever" bipolar disorder indicators, and prior year claims. We compared CCW condition onset dates to identify bipolar disorder diagnosed after dementia. The mean (SD) proportion receiving antipsychotics was 19.6% (11.1%) with bipolar disorder and 18.3% (10.8%) without. The positive predictive value (PPV) of MDS bipolar disorder diagnoses was 80.2% versus CCW lifetime indicators, and 74.6% versus claims. PPV decreased by 27.1% when "bipolar disorder, unspecified" and "other bipolar disorders" diagnoses were excluded. Nearly three-quarters of residents with bipolar disorder had dementia. Over half of those with dementia had dementia first per CCW records. This proportion was lower among those with more specific bipolar disorder diagnoses or MDS bipolar disorder indicators. Bipolar disorder in nursing home residents is often first diagnosed after dementia using nonspecific diagnoses. This practice deserves further evaluation.

The importance of learning from medical error has recently received increasing emphasis. This paper focuses on prescribing errors and argues that, while learning from prescribing errors is a laudable goal, there are currently barriers that can prevent this occurring. Learning from errors can take place on an individual level, at a team level, and across an organisation. Barriers to learning from prescribing errors include the non-discovery of many prescribing errors, lack of feedback to th...

To investigate the relationship between nurse staffing and quality of care in nursing homes in Korea. This study used a cross-sectional design to describe the relationship between nurse staffing and 15 quality-of-care outcomes. Independent variables were hours per resident day (HPRD), skill mix, and turnover of each nursing staff, developed with the definitions of the Centers for Medicare & Medicaid Services and the American Health Care Association. Dependent variables were prevalence of residents who experienced more than one fall in the recent 3 months, aggressive behaviors, depression, cognitive decline, pressure sores, incontinence, prescribed antibiotics because of urinary tract infection, weight loss, dehydration, tube feeding, bed rest, increased activities of daily living, decreased range of motion, use of antidepressants, and use of restraints. Outcome variables were quality indicators from the U.S. Centers for Medicare & Medicaid and 2013 nursing home evaluation manual by the Korean National Health Insurance Service. The effects of registered nurse (RN) HPRD was supported in fall prevention, decreased tube feeding, decreased numbers of residents with deteriorated range of motion, and decreased aggressive behavior. Higher turnover of RNs related to more residents with dehydration, bed rest, and use of antipsychotic medication. Study results supported RNs' unique contribution to resident outcomes in comparison to alternative nurse staffing in fall prevention, decreased use of tube feeding, better range of motion for residents, and decreased aggressive behaviors in nursing homes in Korea. More research is required to confirm the effects of nurse staffing on residents' outcomes in Korea. We found consistency in the effects of RN staffing on resident outcomes acceptable. By assessing nurse staffing levels and compositions of nursing staffs, this study contributes to more effective long-term care insurance by reflecting on appropriate policies, and ultimately

Earlier it has been found that female Seventh-day Adventists (SDA) and Baptists have an increased incidence of psychiatric affective disorders, in contrast to findings that religious practice is associated with better health. In this study, we examined whether the increase in incidence is due to less use of prescribed antidepressants, sedatives and antipsychotics by members of these religious societies than by the general population. In a cohort study, we examined records of all drugs redeemed by 3121 SDA and 2888 Baptists and 29,817 age- and gender-matched members of the general population between 1995 and 2010 in the Danish Prescription Register and compared the prevalence and incidence of use of antidepressants, sedatives and antipsychotics. The prevalence of antidepressant use by women was lower in 1998 but no different from that in controls in 2003 and 2008; the prevalence of antidepressant use by men was higher in both 1998 and 2008 than in the Danish population. The incidence of antidepressant use was lower for female members in 1996-2000, but no difference was observed in the other periods. The prevalence and incidence of use of sedatives and antipsychotics did not consistently differ from those of the general population. The prevalence and incidence of use of antidepressants, sedatives and antipsychotics by female SDA and Baptists were not consistently lower than in the general Danish population. Our findings hence do not explain the increased incidence of psychiatric disorders among female members of these Danish religious societies.

In recent years, psychopharmacological intervention in prodromal psychosis, also known as the ultra-high risk (UHR) mental state for psychosis, has attracted much attention. Whilst it has been shown that antipsychotic use in UHR individuals may be effective in potentially delaying or even averting progression to frank psychosis, their use in subjects that do not necessarily convert to psychosis has raised considerable ethical concerns because of their adverse effects. Recent treatment guidelines for patients at UHR for psychosis recommend the use of antipsychotics only in exceptional conditions and with great precautions. To date only a few studies have investigated the use of antipsychotic medications in UHR patients and the potential benefits and risks related to their use in prodromal psychosis remain unclear. We review here all published studies that included UHR patients treated with antipsychotics, regardless of study design. These studies were all of second-generation antipsychotics, given that first-generation antipsychotics cannot be recommended because of their adverse drug reactions. We specifically examine the available descriptions of adverse reactions of the individual antipsychotic medication in each study and discuss the potential effects of various demographic and clinical factors that may impact on safety issues of pharmacological interventions in UHR patients. Clinical trials to date investigating potential benefits of antipsychotic treatments in preventing transition to psychosis were of relatively short duration and have involved a small number of patients. Whilst it appears that pharmacological intervention at this stage may be effective in both reducing the psychopathology and decreasing transition rates, and is potentially safe, in the absence of sufficient evidence-based knowledge to guide treatment, definitive clinical recommendations and guidelines cannot be derived. Certain adverse events take time to develop, such as metabolic syndrome

This review is one of a series on drugs used to treat fibromyalgia. Fibromyalgia is a clinically well-defined chronic condition of unknown aetiology characterised by chronic widespread pain that often co-exists with sleep problems and fatigue. It affects approximately 2% of the general population. Up to 70% of patients with fibromyalgia meet the criteria for a depressive or anxiety disorder. People often report high disability levels and poor health-related quality of life. Drug therapy focuses on reducing key symptoms and disability, and improving health-related quality of life. Antipsychotics might reduce fibromyalgia and associated mental health symptoms. To assess the efficacy, tolerability and safety of antipsychotics in fibromyalgia in adults. We searched CENTRAL (2016, Issue 4), MEDLINE and EMBASE to 20 May 2016, together with reference lists of retrieved papers and reviews and two clinical trial registries. We also contacted trial authors. We selected controlled trials of at least four weeks duration of any formulation of antipsychotics used for the treatment of fibromyalgia in adults. We extracted the data from all included studies and two review authors independently assessed study risks of bias. We resolved discrepancies by discussion. We performed analysis using three tiers of evidence. We derived first tier evidence from data meeting current best standards and subject to minimal risk of bias (outcome equivalent to substantial pain intensity reduction, intention-to-treat analysis without imputation for drop-outs, at least 200 participants in the comparison, eight to 12 weeks duration, parallel design), second tier evidence from data that failed to meet one or more of these criteria and that we considered at some risk of bias but with adequate numbers in the comparison, and third tier evidence from data involving small numbers of participants that we considered very likely to be biased or used outcomes of limited clinical utility, or both.

Patients are frequently prescribed multiple antipsychotic medications, leading to higher healthcare costs and increased risk for side effects. The efficacy of multiple versus single antipsychotics to prevent acute relapse, measured by incidence of inpatient readmission, is investigated in Arizona, USA. A retrospective chart review compared socio-demographic and clinical data from 1,010 patients discharged on a single and 377 discharged on multiple antipsychotic medications. Case management records were reviewed for readmission within one year of discharge. Younger age, diagnosis of Schizophrenia or Schizoaffective Disorder, prescription of mood stabilizer, shorter length of stay, and discharge to residential treatment or crisis recovery unit were associated with multiple antipsychotics at discharge. Readmission rates of the single (13.7%) versus multiple (15.9%) antipsychotic groups were not statistically different (p=0.286). Logistic regression analysis established that only age (younger) and the prescription of a mood stabilizer at discharge were significant predictors for increased risk for readmission (p=0.010 and p=0.049, respectively). A Cox survival analysis supported these findings. Concomitant antipsychotic polypharmacy at discharge did not reduce readmission risk over a one-year period. Given the increased risk of side effects and financial costs of polypharmacy, this study did not provide evidence to support this practice. Strikingly, only two variables predicted readmission risk, younger age and prescription of mood stabilizer. Although practitioners should follow practice guidelines more closely to prevent unnecessary exposure to potentially lethal side effects of antipsychotic polypharmacy, further studies are needed to better identify patients at high risk for readmission.

Full Text Available Abstract Background Antipsychotic monotherapy is recognized as the treatment of choice for patients with schizophrenia. Simultaneous treatment with multiple antipsychotics (polypharmacy is suggested by some expert consensus guidelines as the last resort after exhausting monotherapy alternatives. This study assessed the annual rate and duration of antipsychotic monotherapy and its inverse, antipsychotic polypharmacy, among schizophrenia patients initiated on commonly used atypical antipsychotic medications. Methods Data were drawn from a large prospective naturalistic study of patients treated for schizophrenia-spectrum disorders, conducted 7/1997–9/2003. Analyses focused on patients (N = 796 who were initiated during the study on olanzapine (N = 405, quetiapine (N = 115, or risperidone (N = 276. The percentage of patients with monotherapy on the index antipsychotic over the 1-year post initiation, and the cumulative number of days on monotherapy were calculated for all patients and for each of the 3 atypical antipsychotic treatment groups. Analyses employed repeated measures generalized linear models and non-parametric bootstrap re-sampling, controlling for patient characteristics. Results During the 1-year period, only a third (35.7% of the patients were treated predominately with monotherapy (>300 days. Most patients (57.7% had at least one prolonged period of antipsychotic polypharmacy (>60 consecutive days. Patients averaged 195.5 days on monotherapy, 155.7 days on polypharmacy, and 13.9 days without antipsychotic therapy. Olanzapine-initiated patients were significantly more likely to be on monotherapy with the initiating antipsychotic during the 1-year post initiation compared to risperidone (p = .043 or quetiapine (p = .002. The number of monotherapy days was significantly greater for olanzapine than quetiapine (p Conclusion Despite guidelines recommending the use of polypharmacy only as a last resort, the use of antipsychotic

A retrospective naturalistic case note study to determine the frequency, co-morbidity and treatment-response of body dysmorphic disorder (BDD). Records from 280 patients attending a highly specialised obsessive-compulsive disorder (OCD)/BDD service were analysed. The clinical outcome was measured either through scoring of the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) for OCD/BDD, or textual analysis of case notes for evidence of symptomatic improvement, treatment tolerability, and premature disengagement. A total of 32 patients (11.43%) were diagnosed with BDD. Of these, 28 (87.5%) had at least one co-morbidity. All patients were offered cognitive behavioural therapy (CBT) and selective serotonin reuptake inhibitor (SSRI). Adjunctive low-dose antipsychotic was prescribed for 21 (66%) patients. Overall, 18/32 (56%) responded, and 7/32 (22%) disengaged prematurely. Patients offered antipsychotic, SSRI and CBT (n = 21) were compared with those offered SSRI and CBT only (n = 11). The treatment was well-tolerated. Whereas there was no significant inter-group difference in the clinical response rate, premature disengagement occurred less frequently in the antipsychotic-treated patients (9.5% versus 45%; Fisher's Exact Test P = 0.0318). BDD frequently presents with co-morbidity, treatment-resistance and premature disengagement. Adjunctive antipsychotic was associated with significantly better treatment adherence, but responder rates did not differ significantly, possibly related to the small sample-size. A well-powered randomised controlled study is warranted, to determine clinical outcomes with adjunctive antipsychotic in BDD.

The purpose of this paper was to compare outpatient consumption and quality of psychotropic drug prescribing between Croatia and Bosnia & Herzegovina 2006-2010. Data on drug utilization from Zagreb Municipal Pharmacy and Sarajevo Public Pharmacy were used to calculate the number of defined daily doses (DDD) and DDD per 1000 inhabitants per day (DDD/TID) using the WHO Anatomical-Therapeutic-Chemical methodology. Total utilization of psychopharmaceuticals increased in both cities; however, it was higher in Zagreb than in Sarajevo throughout the study period. The utilization of psycholeptics increased in Zagreb by 2.4% (from 74.5 to 76.3 DDD/TID) and in Sarajevo by 3.8% (from 62.4 to 64.8 DDD/TID). The utilization of anxiolytics decreased in Zagreb by 2.1% and in Sarajevo by even 18.7%. The utilization of antidepressants increased in both cities with predominance of SSRI over TCA utilization, greater in Sarajevo (96.6%) than in Zagreb (10.2%). The anxiolytic/antidepressant ratio decreased by 11.1% in Zagreb (from 2.87 to 2.55) and by 58.7% in Sarajevo (from 5.66 to 2.34). Outpatient utilization of antipsychotics increased significantly in Sarajevo, predominated by typical ones, whereas in Zagreb the utilization of antipsychotics was stable, predominated by atypical ones. In Croatia and Bosnia & Herzegovina, there was an obvious tendency to follow western trends in drug prescribing, as demonstrated by the increased use of antidepressants and reduced use of anxiolytics. Despite some improvement observed in the prescribing quality, high use of antipsychotics with dominance of typical antipsychotics in Sarajevo points to the need of prescribing guidelines for antipsychotics.

The first generation antipsychotics could establish the possibility of managing many psychotic subjects in an outpatient setting. With the advent of the second (SGA and third generation antipsychotics (TGA, other psychiatric disorders such as bipolar depression, bipolar mania, autism, and major depressive disorder have now been approved for the use of these drugs for their treatment. Also, the administration of more specific assessment tools has allowed for better delineation of the repercussions of these drugs on symptoms and the quality of life of patients who use antipsychotic agents. In general, the SGA share similar mechanisms of action to achieve these results: dopamine-2 receptor antagonism plus serotonin-2A receptor antagonism. The TGA (eg, aripiprazole have partial agonist activity at the dopamine-2 receptor site, and are also called dopaminergic stabilizers. The pharmacological profile of SGA and TGA may provide better efficacy against negative symptoms, and are less likely to produce extrapyramidal symptoms; however, the SGA and TGA are associated with many other adverse events. The clinician has to balance the risks and benefits of these medications when choosing an antipsychotic for an individual patient.Keywords: antipsychotic agents, schizophrenia, pharmacology, safety

The purpose of this nationwide population-based study is to compare the long-term effectiveness of brand-name antipsychotics with generic antipsychotics for treating schizophrenia. We identified patients with schizophrenia who were prescribed antipsychotics from a random sample of one million records from Taiwan's National Health Insurance database, observed between January 1, 2000 and December 31, 2012. Only those with no prior use of antipsychotics for at least 180days were included. We selected patients who were prescribed brand-name risperidone (N=404), generic risperidone (N=145), brand-name sulpiride (N=334), or generic sulpiride (N=991). The effectiveness of the treatments researched in this study consisted of average daily doses, rates of treatment discontinuation, augmentation therapy, and psychiatric hospitalization. We found that compared to patients treated with generic risperidone, those treated with brand-name risperidone required lower daily doses (2.14mg vs. 2.61mg). However, the two groups demonstrated similar rates of treatment discontinuation, augmentation, and psychiatric hospitalization. On the other hand, in comparison with patients prescribed generic sulpiride, those treated with brand-name sulpiride not only required lower daily doses (302.72mg vs. 340.71mg) but also had lower psychiatric admission rates (adjusted hazard ratio: 0.24, 95% confidence interval: 0.10-0.56). In conclusion, for both risperidone and sulpiride, higher daily doses of the respective generic drugs were prescribed than with brand-name drugs in clinical settings. Furthermore, the brand-name sulpiride is more effective at preventing patients from hospitalization than generic sulpiride. These findings can serve as an important reference for clinical practices and healthcare economics for treating schizophrenic patients. Copyright © 2017 Elsevier B.V. All rights reserved.

To evaluate the monitoring of metabolic parameters among outpatients maintained on antipsychotic medications in a general hospital setting in Malaysia and to assess the impact of a local monitoring protocol. By performing a baseline audit of files from a random sample of 300 patients prescribed antipsychotic medications for at least 1 year; we determined the frequency of metabolic monitoring. The findings informed the design of a new local protocol, on which clinical staff was briefed. We re-evaluated metabolic monitoring immediately after implementation, in a small sample of new referrals and current patients. We explored staff perceptions of the initiative with a follow-up focus group, 6 months post-implementation. The baseline audit revealed a sub-optimal frequency of metabolic parameter recording. Re-audit, following implementation of the new protocol, revealed improved monitoring but persisting deficits. Dialogue with the clinical staff led to further protocol modification, clearer definition of staff roles and use of a standard recording template. Focus group findings revealed positive perceptions of the initiative, but persisting implementation barriers, including cultural issues surrounding waist circumference measurement. Responding to challenges in achieving improved routine metabolic monitoring of patients maintained on antipsychotics required on-going dialogue with the clinical staff, in order to address both service pressures and cultural concerns. © The Royal Australian and New Zealand College of Psychiatrists 2015.

To examine the incidence of prescribing errors in a main public hospital in Pakistan and to assess the impact of introducing electronic prescribing system on the reduction of their incidence. Medication errors are persistent in today's healthcare system. The impact of electronic prescribing on reducing errors has not been tested in developing world. Prospective review of medication and discharge medication charts before and after the introduction of an electronic inpatient record and prescribing system. Inpatient records (n = 3300) and 1100 discharge medication sheets were reviewed for prescribing errors before and after the installation of electronic prescribing system in 11 wards. Medications (13,328 and 14,064) were prescribed for inpatients, among which 3008 and 1147 prescribing errors were identified, giving an overall error rate of 22·6% and 8·2% throughout paper-based and electronic prescribing, respectively. Medications (2480 and 2790) were prescribed for discharge patients, among which 418 and 123 errors were detected, giving an overall error rate of 16·9% and 4·4% during paper-based and electronic prescribing, respectively. Electronic prescribing has a significant effect on the reduction of prescribing errors. Prescribing errors are commonplace in Pakistan public hospitals.

Background Long-term treatment with antipsychotic medications in early episode schizophrenia spectrum disorders is common, but both short and long-term effects on the illness are unclear. There have been numerous suggestions that people with early episodes of schizophrenia appear to respond differently than those with multiple prior episodes. The number of episodes may moderate response to drug treatment. Objectives To assess the effects of antipsychotic medication treatment on people with early episode schizophrenia spectrum disorders. Search methods We searched the Cochrane Schizophrenia Group register (July 2007) as well as references of included studies. We contacted authors of studies for further data. Selection criteria Studies with a majority of first and second episode schizophrenia spectrum disorders comparing initial antipsychotic medication treatment with placebo, milieu, or psychosocial treatment. Data collection and analysis Working independently, we critically appraised records from 681 studies, of which five studies met inclusion criteria. We calculated risk ratios (RR) and their 95% confidence intervals (CI) where possible. For continuous data, we calculated mean difference (MD). We calculated numbers needed to treat/harm (NNT/NNH) where appropriate. Main results Five studies (combined total n=998) met inclusion criteria. Four studies (n=724) provided leaving the study early data and results suggested that individuals treated with a typical antipsychotic medication are less likely to leave the study early than those treated with placebo (Chlorpromazine: 3 RCTs n=353, RR 0.4 CI 0.3 to 0.5, NNT 3.2, Fluphenaxine: 1 RCT n=240, RR 0.5 CI 0.3 to 0.8, NNT 5; Thioridazine: 1 RCT n=236, RR 0.44 CI 0.3 to 0.7, NNT 4.3, Trifulperazine: 1 RCT n=94, RR 0.96 CI 0.3 to 3.6). Two studies contributed data to assessment of adverse effects and present a general pattern of more frequent side effects among individuals treated with typical antipsychotic medications
Full Text Available Abstract Background Little is known about the factors influencing treatment choice in psychosis, the majority of this work being conducted with specialists (consultant in psychiatry. We sought to examine trainees' choices of treatment for psychosis if they had to prescribe it for themselves, their patients, and factors influencing decision-making. Methods Cross-sectional, semi-structured questionnaire-based study. Results Of the 726 respondents (response rate = 66%, the majority chose second-generation antipsychotics (SGAs if they had to prescribe it for themselves (n = 530, 93% or for their patients (n = 546, 94%. The main factor influencing choice was perceived efficacy, 84.8% (n = 475 of trainees stating this was the most important factor for the patient, and 77.8% (n = 404 stating this was the most important factor for their own treatment. Trainees with knowledge of trials questioning use of SGAs (CATIE, CUtLASS, TEOSS were more likely to choose second-generation antipsychotics than those without knowledge of these trials (χ2 = 3.943; p = 0.047; O.R. = 2.11; 95% C.I. = 1.0-4.48. Regarding psychotherapy, cognitive behavioural therapy (CBT was the most popular choice for self (33.1%; n = 240 and patient (30.9%; n = 224. Trainees were significantly more likely to prefer some form of psychotherapy for themselves rather than patients (χ2 = 9.98; p Conclusions Trainees are more likely to choose second-generation antipsychotic medication for patients and themselves. Despite being aware of evidence that suggests otherwise, they predominantly base these choices on perceived efficacy.

Product monographs (also known by terms such as Summary of Product Characteristics and Highlights of Prescribing Information, depending on the jurisdiction) provide essential information to ensure the safe and effective use of a drug. Medical practitioners often rely on these monographs for guidance on matters related to pharmacokinetics as well as indications, contraindications, clinical pharmacology, and adverse reactions. The clinical and scientific information found within these documents, forming the basis for decision making, are presumed to be derived from well-designed studies. The objective of this review is to examine the source and validity of the pharmacokinetic data used in establishing the half-lives and times to steady-state reported in the product monographs of second-generation long-acting injectable antipsychotics. Thus, we have critically evaluated the clinical trials from which the pharmacokinetic parameters listed in the product monographs were determined. In many cases, the pharmacokinetic information presented in product monographs is of limited use to clinicians wishing to optimize the effectiveness and tolerability of second-generation long-acting injectable antipsychotics. Under such circumstances, off-label prescribing practices may actually produce better clinical outcomes than if decisions were made based on the product monographs alone.

Objectives The purpose of this study is to examine the use of prescribed psychoactive medications in a prospective cohort of children shortly after they entered foster homes; and to identify demographics, maltreatment history, psychiatric diagnoses including ADHD comorbidity, and level of aggression that contribute to prescribed use of stimulant and atypical antipsychotic medication over time. Methods The sample included N = 252 children (nested in 95 sibling groups) followed for three years up to 4 yearly waves. Results Nearly all (89%) met criteria for at least one of eight psychiatric diagnoses and 31% (75/252) used one or more prescribed psychoactive medications. Over half (55%) were diagnosed with Attention Deficit Hyperactivity Disorder (ADHD); of these 38% used stimulants and 36% used atypical antipsychotics. Of the 75 medicated children, 19% received ≥3 different classes of drugs over the course of the study. Stimulants (69%) and atypical antipsychotics (65%) were the most frequently used drugs among medicated children. Adjusted odds ratios (AOR) showed that male gender (AOR = 3.2; 95% CI = 1.5–9.3), African American vs Latino ethnicity (AOR = 5.4; 95% CI = 2.1–14.2), ADHD regardless of Oppositional Defiant (ODD) or Conduct (CD) comorbidity (AOR = 6.0, 95% CI = 1.3–27.5), ODD or CD (AOR = 11.1, 95% CI = 2.1–58.6), and Separation Anxiety (AOR = 2.0, 95% CI = 1.0–4.0) psychiatric disorders were associated with the use of prescribed stimulants; while male gender (AOR = 3.8, 95% CI = 1.5–9.3), African American vs Latino (AOR = 5.1, 95% CI = 1.2–9.2) or Mixed/Other ethnicity (AOR = 3.3, 95% CI = 1.9–13.7), ADHD regardless of ODD or CD comorbidity (AOR = 5.8, 95% CI = 1.2–28.7), ODD or CD (AOR = 13.9, 95% CI = 3.3–58.5), Major Depression/Dysthymia (AOR = 2.8, 95% CI = 1.1–6.7) psychiatric disorders, and history of sexual abuse (AOR = 4.6, 95

Background In many countries of the industrialised world second generation (atypical) antipsychotics have become first line drug treatments for people with schizophrenia. The question as to whether, and if so how much, the effects of the various second generation antipsychotics differ is a matter of debate. In this review we examine how the efficacy and tolerability of aripiprazole differs from that of other second generation antipsychotics. Objectives To evaluate the effects of aripiprazole compared with other atypical antipsychotics for people with schizophrenia and schizophrenia-like psychoses. Search methods We searched the Cochrane Schizophrenia Group Trials Register (March 2007) which is based on regular searches of BIOSIS, CENTRAL, CINAHL, EMBASE, MEDLINE and PsycINFO. Selection criteria We included all randomised trials comparing oral aripiprazole with oral forms of amisulpride, clozapine, olanzapine, quetiapine, risperidone, sertindole, ziprasidone or zotepine in people with schizophrenia or schizophrenia-like psychoses. Data collection and analysis We extracted data independently. For dichotomous data we calculated relative risks (RR) and their 95% confidence intervals (CI) on an intention-to-treat basis based on a random-effects model. We calculated numbers needed to treat/harm (NNT/NNH) where appropriate. For continuous data, we calculated weighted mean differences (MD) again based on a random-effects model. Main results The review currently includes four trials with 1404 participants on two out of eight possible comparisons - aripiprazole versus olanzapine and aripiprazole versus risperidone. The overall number of participants leaving the studies early was considerable (38.5%), limiting the validity of the findings, but with no significant differences between groups. Aripiprazole was less efficacious than olanzapine in terms of the general mental state (PANSS total score: n=794, 2 RCTs, MD 4.96 CI 1.85 to 8.06), but it was associated with fewer side

Full Text Available Satisfying sexual experience is an essential part of a healthy and enjoyable life for most people. Antipsychotic drugs are among the various factors that affect optimal sexual functioning. Both conventional and novel antipsychotics are associated with significant sexual side effects. This review has presented various studies comparing different antipsychotic drugs. Dopamine antagonism, increased serum prolactin, serotonergic, adrenergic and cholinergic mechanisms are all proposed to be the mechanisms for sexual dysfunction. Drug treatment for this has not given satisfactory long-term results. Knowledge of the receptor pharmacology of an individual antipsychotic will help to determine whether it is more or less likely to cause sexual side effects and its management.

The aim of this study is to evaluate the impact of the Canterbury earthquakes on the mental health of the local population by examining prescribing patterns of psychotropic medication. Dispensing data from community pharmacies for antidepressants, antipsychotics, anxiolytics and sedatives/hypnotics are routinely recorded in a national database. The close relationship between prescribing and dispensing provides the opportunity to assess prescribing trends for Canterbury compared to national data and therefore examines the longitudinal impact of the earthquakes on prescribing patterns. Short-term increases in the use of anxiolytics and sedatives/hypnotics were observed after the most devastating February 2011 earthquake, but this effect was not sustained. There were no observable effects of the earthquakes on antidepressant or antipsychotic dispensing. Short-term increases in dispensing were only observed for the classes of anxiolytics and sedatives/hypnotics. No sustained changes in dispensing occurred. These findings suggest that long-term detrimental effects on the mental health of the Canterbury population were either not present or have not resulted in increased prescribing of psychotropic medication. © The Royal Australian and New Zealand College of Psychiatrists 2015.

Non-adherence was more frequent in male than in female psychiatric patients. This multi-center study in China examined the gender difference with regard to attitude towards antipsychotic medications and its associations with socio-demographic variables, insight, and psychopathology. Patients' basic socio-demographic and clinical data were collected. Psychopathology and insight were measured with the Symptom Checklist-90 (SCL-90) and the Insight and Treatment Attitudes Questionnaire (ITAQ), respectively. Their attitudes towards antipsychotic medications were assessed by two standardized questions. Nearly 39.6% (109/275) males and 31.1% (70/225) females reported negative attitudes towards antipsychotic medications. Binary logistic regression revealed that in males single marital status (OR=2.9, 95% CI=1.3-6.4), rural residence (OR=0.4, 95% CI=0.2-0.7), longer duration of schizophrenia (OR=1.0, 95% CI=1.0-1.1), knowledge of medication (OR=1.5, 95% CI=1.3-1.6) and the SCL-90 hostility subscale (OR=0.9, 95% CI=0.9-1.0) were contributors to negative attitudes. In female patients, knowledge about medications (OR=1.4, 95% CI=1.3-1.6), the SCL-90 somatization (OR=0.8, 95% CI=0.8-0.9) and anxiety (OR=1.1, 95% CI=1.0-1.2) subscales were contributors to negative attitudes. The study suggested that different psychosocial and clinical factors accounted for the negative attitude towards antipsychotic treatment in male and female patients.

of potential negative consequences (ie increased risk of osteoporosis or neoplasia, worsening of psychopathology) (34). When hyperprolactinemia is symptomatic, lowering of the dose of the antipsychotic, or switching to a prolactin-sparing agent (olanzapine, quetiapine, aripiprazole and clozapine) is recommended. Before this, women with amenorrhea secondary to antipsychotic-induced hyperprolactinemia should be advised that menses may resume. Especially after long-standing amenorrhea they may assume being menopaused, hence may believe birth control measures are no longer required. The prevalence of antipsychotic-induced sexual and reproductive function side-effects is high. Clinicians should be aware of them, because they are often badly tolerated, are associated with a low satisfaction and may therefore result in low adherence with treatment. This implies for the clinician to overtly discuss with the patient of his sexuality and the potential negative impact of antipsychotic treatment on it. The recognition of these problems allows the searching together for a solution. The described cases indicate that solving the problem is often possible, provided that individual preferences and subjective impact are taken in account. Antipsychotic treatment is often prescribed for very long periods. A better knowledge of - and attention to - the associated side effects, particularly on the sexual and reproductive functions, is necessary in order to reduce some potentially negative long-term effects and to improve the adherence to treatment of our patients.

Background In many countries of the industrialised world second generation (atypical) antipsychotics have become the first line drug treatment for people with schizophrenia. The question as to whether and, if so, how much the effects of the various second generation antipsychotics differ is a matter of debate. Objectives To evaluate the effects of sertindole compared with other second generation antipsychotics for people with schizophrenia and schizophrenia-like psychosis. Search methods We searched the Cochrane Schizophrenia Group Trials Register (April 2007) and ClinicalTrials.gov (February 2009). Selection criteria We included all randomised trials comparing oral sertindole with oral forms of amisulpride, aripiprazole, clozapine, olanzapine, quetiapine, risperidone, ziprasidone or zotepine for people with schizophrenia or schizophrenia-like psychosis. Data collection and analysis We extracted data independently. For dichotomous data we calculated relative risks (RR) and their 95% confidence intervals (CI) on an intention-to-treat basis based on a random-effects model. For continuous data, we calculated weighted mean differences (WMD) again based on a random-effects model. Main results The review currently includes two short-term low-quality randomised trials (total n=508) both comparing sertindole with risperidone. One third of participants left the studies early (2 RCTs, n=504, RR 1.23 CI 0.94 to 1.60). There was no difference in efficacy (2 RCTs, n=493, WMD PANSS total change from baseline 1.98 CI −8.24 to 12.20). Compared with relatively high doses of risperidone (between 4 and 12 mg/day), sertindole produced significantly less akathisia and parkinsonism (1 RCT, n=321, RR 0.24 CI 0.09 to 0.69, NNT 14, CI 8 to 100). Sertindole produced more cardiac effects (2 RCTs, n=508, RR QTc prolongation 4.86 CI 1.94 to 12.18), weight change (2 RCTs, n=328, WMD 0.99 CI 0.12 to 1.86) and male sexual dysfunction (2 RCTs, n=437, RR 2.90 CI 1.32 to 6.35, NNH 13 CI 8 to 33

There is a long history of using antipsychotic medications in the treatment of depressive disorders. Atypical antipsychotics, which have fewer side effects than traditional antipsychotics, have been used as monotherapy or adjunctively with antidepressants to treat depressive disorders with or without psychotic symptoms. The antidepressant effect of atypical antipsychotics involves regulation of monoamine, glutamate, gamma-aminobutyric acid (GABA), cortisol, and neurotrophic factors. To date, the United States Food and Drug Administration (USFDA) has approved aripiprazole and quetiapine slow-release tablets as adjunctive treatment for depressive disorders, and the combination of olanzapine and fluoxetine for the treatment of treatment-resistant depression. When using atypical antipsychotics in the treatment of depressed patients, clinicians need to monitor patients for the emergence of adverse effects including extrapyramidal symptoms (EPS), weight gain, and hyperglycemia.
Full Text Available Antipsychotic drugs (APDs are widely prescribed to control various mental disorders. As mental disorders are chronic diseases, these drugs are often used over a life-time. However, APDs can cause serious glucometabolic side-effects including type 2 diabetes and hyperglycaemic emergency, leading to medication non-compliance. At present, there is no effective approach to overcome these side-effects. Understanding the mechanisms for APD-induced diabetes should be helpful in prevention and treatment of these side-effects of APDs and thus improve the clinical outcomes of APDs. In this review, the potential mechanisms for APD-induced diabetes are summarized so that novel approaches can be considered to relieve APD-induced diabetes. APD-induced diabetes could be mediated by multiple mechanisms: (1 APDs can inhibit the insulin signaling pathway in the target cells such as muscle cells, hepatocytes and adipocytes to cause insulin resistance; (2 APD-induced obesity can result in high levels of free fatty acids (FFA and inflammation, which can also cause insulin resistance. (3 APDs can cause direct damage to β-cells, leading to dysfunction and apoptosis of β-cells. A recent theory considers that both β-cell damage and insulin resistance are necessary factors for the development of diabetes. In high-fat diet-induced diabetes, the compensatory ability of β-cells is gradually damaged, while APDs cause direct β-cell damage, accounting for the severe form of APD-induced diabetes. Based on these mechanisms, effective prevention of APD-induced diabetes may need an integrated approach to combat various effects of APDs on multiple pathways.

The question as to whether, and if so how much, the effects of the various second generation antipsychotics differ is a matter of debate. In this review we examine how the efficacy and tolerability of amisulpride differs from that of other second generation antipsychotics. Objectives To evaluate the effects of amisulpride compared with other atypical antipsychotics for people with schizophrenia and schizophrenia-like psychoses. Search methods We searched the Cochrane Schizophrenia Group Trials Register (April 2007) which is based on regular searches of BIOSIS, CINAHL, EMBASE, MEDLINE and PsycINFO. We updated this search in July 2012 and added 47 new trials to the awaiting classification section. Selection criteria We included randomised, at least single-blind, trials comparing oral amisulpride with oral forms of aripiprazole, clozapine, olanzapine, quetiapine, risperidone, sertindole, ziprasidone or zotepine in people with schizophrenia or schizophrenia-like psychoses. Data collection and analysis We extracted data independently.

Main results The review currently includes ten short to medium term trials with 1549 participants on three comparisons: amisulpride versus olanzapine, risperidone and ziprasidone. The overall attrition rate was considerable (34.7%) with no significant difference between groups. Amisulpride was similarly effective as olanzapine and risperidone and more effective than ziprasidone (leaving the study early due to inefficacy: n=123, 1 RCT, RR 0.21 CI 0.05 to 0.94, NNT 8 CI 5 to 50

The Child and Adolescent First-Episode Psychosis Study (CAFEPS) is a naturalistic longitudinal study of early-onset first psychotic episodes. This report describes the antipsychotic treatment during the first year and compares the most frequently used agents after 6 months. Participants were 110 patients, aged 9-17 years, with a first psychotic episode attended consecutively at six different centers. The Positive and Negative Symptom Scale (PANSS), Clinical Global Impressions (CGI), Disability Assessment Schedule (DAS), and Global Assessment of Function (GAF) scales were administered at baseline and at 6 months and the Udvalg for Kliniske Undersøgelser (UKU) Side Effects Rating Scale only at 6 months. Diagnoses at baseline were 38.2% psychotic disorder not otherwise specified, 39.1% schizophrenia-type disorder, 11.8% depressive disorder with psychotic symptoms, and 10.9% bipolar disorder, manic episode with psychotic symptoms. The most frequently used antipsychotic agents were risperidone (n = 50), quetiapine (n = 18), and olanzapine (n = 16). Patients who were prescribed olanzapine or quetiapine had more negative and general symptoms. Using the baseline score as covariate, no significant differences were found in the reductions on any scale in patients treated with risperidone, quetiapine, or olanzapine for 6 months. Weight increase was greater with olanzapine than with risperidone (p = 0.020) or quetiapine (p = 0.040). More neurological side effects appeared with risperidone than with olanzapine (p = 0.022). All side effects were mild or moderate. Second-generation antipsychotics, especially risperidone, quetiapine, and olanzapine, are the most used in our context in first psychotic episodes in children and adolescents. These three obtain similar clinical improvement, but differ in their side effects.

In 2010, the American Diabetes Association (ADA) proposed that individuals with fasting glucose level of 100-125 mg/dL (5.6-6.9 mmol/L) or glucose level of 140-199 mg/dL (7.8-11.0 mmol/L) 2 hours after a 75-g oral glucose tolerance test or hemoglobin A(1c) 5.7%-6.4% be classified as prediabetic, indicating increased risk for the emergence of diabetes mellitus. At the same time, the ADA formulated guidelines for the use of metformin for the treatment of prediabetes. To determine the prevalence of prediabetes in a cohort of psychiatrically ill adults receiving antipsychotics and to compare the clinical and metabolic features of prediabetic patients with those of patients with normal glucose tolerance and those with diabetes mellitus. The 2010 ADA criteria were applied to a large, consecutive, single-site European cohort of 783 adult psychiatric inpatients (mean age: 37.6 years) without a history of diabetes who were receiving antipsychotics. All patients in this cross-sectional study underwent measurement of body mass index (BMI), waist circumference, oral glucose tolerance test, and fasting insulin and lipids from November 2003 through July 2007. 413 patients (52.8%) had normal glucose tolerance, 290 (37.0%) had prediabetes, and 80 (10.2%) had diabetes mellitus. The fasting glucose and/or hemoglobin A(1c) criteria were met by 89.7% of prediabetic patients. A statistically significant intergroup gradient from normal glucose tolerance to prediabetes and from prediabetes to diabetes mellitus was observed for waist circumference, triglycerides, fasting insulin levels, and frequency of metabolic syndrome (P = .02 to P prediabetic patients (6.6%) met the 2010 ADA criteria for treatment with metformin. Prediabetes is highly prevalent in adults treated with antipsychotic drugs and correlates with markers of increased intraabdominal adiposity, enhanced lipolysis, and insulin resistance. Criteria for using metformin to prevent the emergence of diabetes mellitus may need to be

Schizoaffective disorder (SAD) is an incapacitating illness that presents clinicians with challenges in terms of both its diagnosis and its psychopharmacological management. Most studies conducted on the psychopharmacological treatment of SAD also include patients with schizophrenia or other psychotic illnesses, thereby providing an unspecific view to the clinician as to the best way of treating patients with SAD. The objective of this article is to review studies on evidence-based treatment of patients with SAD. We conducted a systematic literature search in MEDLINE/PubMed for full-text studies in the English language using the terms 'Schizoaffective and treatment' or 'antipsychotic schizoaffective'. Our review found relatively few studies with either an active comparator or placebo that examined the efficacy of antipsychotics for patients with SAD without an admixture of patients with schizophrenia. Only oral paliperidone extended release (ER), paliperidone long-acting injection (LAI), and risperidone have been shown to be effective and safe in reducing psychotic as well as affective components in acutely ill SAD patients in controlled studies. Paliperidone ER and LAI have also been shown to be efficacious in the maintenance treatment phase of SAD patients. While no supportive data exist, it is possible that other atypical antipsychotics may have similar efficacy to the two mentioned above. We conclude with a number of research recommendations for the study of treatment options for patients with SAD. First, there is a need for studies with patients specifically diagnosed with SAD for both the acute and the maintenance phase. The sample size needs to be adequate to allow a primary analysis of efficacy and to allow for analysis of the SAD subtypes: depressed and bipolar. Another recommendation is the need for studies of patients with SAD stratified into patients with and without mood stabilizers or antidepressants to allow the examination of the adjunctive role of
Full Text Available Abstract Background The aim of the present study was to describe the use of prescribed and non prescribed medicines in a non-institutionalised population older than 15 years of an urban area during the year 2000, in terms of age and gender, social class, employment status and type of Primary Health Care. Methods Cross-sectional study. Information came from the 2000 Barcelona Health Interview Survey. The indicators used were the prevalence of use of prescribed and non-prescribed medicines in the two weeks prior to the interview. Descriptive analyses, bivariate and multivariate logistic regression analyses were carried out. Results More women than men took medicines (75.8% vs. 60% respectively. The prevalence of use of prescribed medicines increased with age while the prevalence of non-prescribed use decreased. These age differences are smaller among those with poor perceived health. In terms of social class, a higher percentage of men with good health in the more advantaged classes took non-prescribed medicines compared with disadvantaged classes (38.7% vs 31.8%. In contrast, among the group with poor health, more people from the more advantaged classes took prescribed medicines, compared with disadvantaged classes (51.4% vs 33.3%. A higher proportion of people who were either retired, unemployed or students, with good health, used prescribed medicines. Conclusion This study shows that beside health needs, there are social determinants affecting medicine consumption in the city of Barcelona.

Full Text Available There is increasing use of antipsychotic drugs in pediatric and psychiatry practice for a wide range of behavioral and affective disorders. These drugs have prominent side effects of interest to pediatric endocrinologists, including weight gain and associated metabolic risk factors and hyperprolactinemia. The drugs block dopamine action, thus disinhibiting prolactin secretion. Hyperprolactinemia is especially prominent with first-generation antipsychotics such as haloperidol and the second-generation drugs, most commonly risperidone, with some patients developing gynecomastia or galactorrhea or, as a result of prolactin inhibition of gonadotropin releasing hormone from the hypothalamus, amenorrhea. With concern about the long-term effects of antipsychotics on bone mass and pituitary tumor formation, it is prudent to monitor serum prolactin levels in antipsychotic drug-treated pediatric patients and consider treatment with an agent less likely to induce hyperprolactinemia.

CONTEXT Schizophrenic symptoms are linked to a dysfunction of dopamine neurotransmission and the brain reward system. However, it remains unclear whether antipsychotic treatment, which blocks dopamine transmission, improves, alters, or even worsens the reward-related abnormalities. OBJECTIVE....... Antipsychotic treatment tends to normalize the response of the reward system; this was especially seen in the patients with the most pronounced treatment effect on the positive symptoms. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT01154829....... To investigate changes in reward-related brain activations in schizophrenia before and after antipsychotic monotherapy with a dopamine D2/D3 antagonist. DESIGN Longitudinal cohort study.

Full Text Available Abstract Background Atypical antipsychotics are increasingly used for treatment of mental illnesses like schizophrenia and bipolar disorder, and considered to have fewer extrapyramidal effects than older antipsychotics. Methods We examined efficacy in randomised trials of bipolar disorder where the presenting episode was either depression, or manic/mixed, comparing atypical antipsychotic with placebo or active comparator, examined withdrawals for any cause, or due to lack of efficacy or adverse events, and combined all phases for adverse event analysis. Studies were found through systematic search (PubMed, EMBASE, Cochrane Library, and data combined for analysis where there was clinical homogeneity, with especial reference to trial duration. Results In five trials (2,206 patients participants presented with a depressive episode, and in 25 trials (6,174 patients the presenting episode was manic or mixed. In 8-week studies presenting with depression, quetiapine and olanzapine produced significantly better rates of response and symptomatic remission than placebo, with NNTs of 5–6, but more adverse event withdrawals (NNH 12. With mania or mixed presentation atypical antipsychotics produced significantly better rates of response and symptomatic remission than placebo, with NNTs of about 5 up to six weeks, and 4 at 6–12 weeks, but more adverse event withdrawals (NNH of about 22 in studies of 6–12 weeks. In comparisons with established treatments, atypical antipsychotics had similar efficacy, but significantly fewer adverse event withdrawals (NNT to prevent one withdrawal about 10. In maintenance trials atypical antipsychotics had significantly fewer relapses to depression or mania than placebo or active comparator. In placebo-controlled trials, atypical antipsychotics were associated with higher rates of weight gain of ≥7% (mainly olanzapine trials, somnolence, and extrapyramidal symptoms.

• Metabolic disturbances represent a well-known side effect of second generation antipsychotics. However, studies comparing second generation antipsychotic drugs (SGAPs) and first generation antipsychotic drugs (FGAPs) through administrative databases have shown contrasting findings, which may be attributable to methodological differences. • The definition of antipsychotic exposure impacts on the association between antipsychotics and metabolic risk in studies carried out through administrative databases. • Considering cumulative exposure to antipsychotics or including patients exposed to an antipsychotic drug for months or years is likely to over-represent patients who tolerate the drug well with a depletion of susceptible effects. • Antipsychotic drug exposure is a time-varying determinant and episodes of no use, past use and current use should be distinguished over the study period to avoid any misclassification bias that might lead to misleading findings. To assess the influence of three definitions of antipsychotic exposure on the comparison between first generation (FGAP) and second generation (SGAP) antipsychotic drugs and 'conventional' mood stabilizers towards the risk of metabolic events using (i) a dichotomous measure (exposed/non-exposed over the follow-up), (ii) a categorical measure taking into account the chronology of exposure at the time of the metabolic event (current, recent and no use) and (iii) a continuous measure (cumulative duration). A historical fixed cohort was identified from the 2004-2006 claims database of the French health insurance programme for self-employed workers, including 3172 patients aged 18 years and over who used conventional mood stabilizers over a 3 month period. A metabolic event was defined as an incident dispensing of an anti-diabetic or lipid-lowering drug. A metabolic event occurred in 367 patients (11.6%). At least one FGAP had been prescribed in 29% of patients who did not develop a metabolic event and in

In this article, we explore the penetration of generic atypical antipsychotics in the United States market before and after the availability of generic risperidone in July 2008. Analysis suggests that, overall, generic penetration into the atypical antipsychotic market has grown from approximately three percent in January 2008 to more than 25 percent in December 2009. Similar trends are uncovered when branded and generic prescriptions are analyzed by specialty.

Risperidone is one of the 'new generation' antipsychotics. As well as its reputed tendency to cause fewer movement disorders than the older drugs such as chlorpromazine and haloperidol, it is claimed that risperidone may improve negative symptoms. To evaluate the effects of risperidone for schizophrenia in comparison to 'conventional' neuroleptic drugs. The original electronic searches of Biological Abstracts (1980-1997), Cochrane Schizophrenia Group's Register (1997), The Cochrane Library (1997, Issue 1), EMBASE (1980-1997), MEDLINE (1966-1997), PsycLIT (1974-1997), and SCISEARCH (1997) were updated with a new electronic search of the same databases in 2002. The search term used in the update was identical to that used in 1997. Any new studies or relevant references were added to the review. In addition, references of all identified studies were searched for further trial citations. Pharmaceutical companies and authors of trials were also contacted. All randomised trials comparing risperidone to any 'conventional' neuroleptic treatment for people with schizophrenia or other similar serious mental illnesses. Citations and, where possible, abstracts were independently inspected by reviewers, papers ordered, re-inspected and quality assessed. Data were also independently extracted. Where possible, sensitivity analyses on dose of risperidone, haloperidol and duration of illness were undertaken for the primary outcomes of clinical improvement, side effects (movement disorders) and acceptability of treatment. For homogeneous dichotomous data the Relative Risk (RR), 95% confidence interval (CI) and, where appropriate, the number needed to treat/harm (NNT/H) were calculated on an intention-to-treat basis. In the short-term, risperidone was more likely to produce an improvement in the Positive and Negative Syndrome Scale (PANSS) when compared with haloperidol (n=2368, 9 RCTs, RR not 20% improved 0.72 CI 0.59 to 0.88 NNT 8). A similar, favourable outcome for risperidone was
Full Text Available A high dose of delta9-tetrahydrocannabinol, the main Cannabis sativa (cannabis component, induces anxiety and psychotic-like symptoms in healthy volunteers. These effects of delta9-tetrahydrocannabinol are significantly reduced by cannabidiol (CBD, a cannabis constituent which is devoid of the typical effects of the plant. This observation led us to suspect that CBD could have anxiolytic and/or antipsychotic actions. Studies in animal models and in healthy volunteers clearly suggest an anxiolytic-like effect of CBD. The antipsychotic-like properties of CBD have been investigated in animal models using behavioral and neurochemical techniques which suggested that CBD has a pharmacological profile similar to that of atypical antipsychotic drugs. The results of two studies on healthy volunteers using perception of binocular depth inversion and ketamine-induced psychotic symptoms supported the proposal of the antipsychotic-like properties of CBD. In addition, open case reports of schizophrenic patients treated with CBD and a preliminary report of a controlled clinical trial comparing CBD with an atypical antipsychotic drug have confirmed that this cannabinoid can be a safe and well-tolerated alternative treatment for schizophrenia. Future studies of CBD in other psychotic conditions such as bipolar disorder and comparative studies of its antipsychotic effects with those produced by clozapine in schizophrenic patients are clearly indicated.

Full Text Available The use of antipsychotics in very young children is of concern given the lack of empirical evidence in their efficacy and long-term impact on children’s health. This study examined the prescription of antipsychotics among children aged ≤5 years enrolled in a state Medicaid program. Secondary data analysis was conducted using the Medicaid administrative data of a southeastern state. Using SAS 9.3, descriptive statistics were performed to examine socio-demographic characteristics, psychiatric diagnoses, off-label use, receipt of medications from multiple psychotropic drug classes, and receipt of non-pharmacologic psychiatric services among children aged ≤5 years who received antipsychotic prescriptions in calendar year (CY 2011. A total of 112 children in the target age group received antipsychotics in CY 2011, the most common prescription being risperidone. The most common listed psychiatric diagnosis was attention deficit hyperactivity disorder. Two in five children received antipsychotics for off-label use. Three in four children also received medications from at least one other psychotropic drug class. More than half did not receive adjunct psychiatric services. State-level policies offering specific guidance and recommendations for antipsychotic use among very young children are urgently needed. Future research is warranted to examine long-term impact of such practices on children’s growth and development.

Full Text Available Channeling occurs when a medication and its potential comparators are selectively prescribed based on differences in underlying patient characteristics. Drug safety advisories can provide new information regarding the relative safety or effectiveness of a drug product which might increase selective prescribing. In particular, when reported adverse effects vary among drugs within a therapeutic class, clinicians may channel patients toward or away from a drug based on the patient's underlying risk for an adverse outcome. If channeling is not identified and appropriately managed it might lead to confounding in observational comparative effectiveness studies.To demonstrate channeling among new users of second generation antipsychotics following a Food and Drug Administration safety advisory and to evaluate the impact of channeling on cardiovascular risk estimates over time.Florida Medicaid data from 2001-2006.Retrospective cohort of adults initiating second generation antipsychotics. We used propensity scores to match olanzapine initiators with other second generation antipsychotic initiators. To evaluate channeling away from olanzapine following an FDA safety advisory, we estimated calendar time-specific propensity scores. We compare the performance of these calendar time-specific propensity scores with conventionally-estimated propensity scores on estimates of cardiovascular risk.Increased channeling away from olanzapine was evident for some, but not all, cardiovascular risk factors and corresponded with the timing of the FDA advisory. Covariate balance was optimized within period and across all periods when using the calendar time-specific propensity score. Hazard ratio estimates for cardiovascular outcomes did not differ across models (Conventional PS: 0.97, 95%CI: 0.81-3.18 versus calendar time-specific PS: 0.93, 95%CI: 0.77-3.04.Changes in channeling over time was evident for several covariates but had limited impact on cardiovascular risk

Background In many countries of the industrialised world second generation (’atypical’) antipsychotic drugs have become the first line drug treatment for people with schizophrenia. It is not clear how the effects of the various second generation antipsychotic drugs differ. Objectives To evaluate the effects of quetiapine compared with other second generation antipsychotic drugs for people with schizophrenia and schizophrenia-like psychosis. Search methods We searched the Cochrane Schizophrenia Group Trials Register (April 2007), inspected references of all identified studies, and contacted relevant pharmaceutical companies, drug approval agencies and authors of trials for additional information. Selection criteria We included all randomised control trials comparing oral quetiapine with oral forms of amisulpride, aripiprazole, clozapine, olanzapine, risperidone, sertindole, ziprasidone or zotepine in people with schizophrenia or schizophrenia-like psychosis. Data collection and analysis We extracted data independently. For dichotomous data we calculated relative risks (RR) and their 95% confidence intervals (CI) on an intention-to-treat basis based on a random-effects model. We calculated numbers needed to treat/harm (NNT/NNH) where appropriate. For continuous data, we calculated weighted mean differences (WMD) again based on a random-effects model. Main results The review currently includes 21 randomised control trials (RCTs) with 4101 participants. These trials provided data on four comparisons - quetiapine versus clozapine, olanzapine, risperidone or ziprasidone. A major limitation to all findings is the high number of participants leaving studies prematurely (57.6%) and the substantial risk of biases in studies. Efficacy data favoured olanzapine and risperidone compared with quetiapine (PANSS total score versus olanzapine:10 RCTs, n=1449, WMD 3.66 CI 1.93 to 5.39; versus risperidone: 9 RCTs, n=1953, WMD 3.09 CI 1.01 to 5.16), but clinical meaning is unclear

Background In many parts of the world, particularly in industrialised countries, second generation (atypical) antipsychotic drugs have become first line treatment for people suffering from schizophrenia. The question as to whether the effects of various second generation antipsychotic drugs differ is a matter of debate. Objectives To evaluate the effects of zotepine compared with other second generation antipsychotic drugs for people suffering from schizophrenia and schizophrenia-like psychoses. Search methods We searched the Cochrane Schizophrenia Group Trials Register (November 2009), inspected references of all identified studies for further trials and contacted authors of trials for additional information. Selection criteria We included only randomised clinical controlled trials that compared zotepine with any forms of amisulpride, aripiprazole, clozapine, olanzapine, risperidone, sertindole or ziprasidone in people suffering from only schizophrenia or schizophrenia-like psychoses. Data collection and analysis SS and KK extracted data independently. For dichotomous data we calculated relative risks (RR) and their 95% confidence intervals (CI) on an intention-to-treat basis based on a random-effects model. For continuous data, we calculated weighted mean differences (MD) again based on a random-effects model. Main results We included three studies (total n=289; 2 RCTs zotepine vs clozapine; 1 RCT zotepine vs clozapine vs risperidone (at 4 mg, 8 mg doses) vs remoxipride. All studies were of limited methodological quality. When zotepine was compared with clozapine, it was clozapine that was found to be more effective in terms of global state (n=59, 1 RCT, RR No clinically significant response 8.23 CI 1.14 to 59.17). Mental state scores also favoured clozapine (n=59, 1 RCT, MD average score (BPRS total, high = poor) 6.00 CI 2.17 to 9.83) and there was less use of antiparkinson medication in the clozapine group (n=116, 2 RCTs, RR 20.96 CI 2.89 to 151.90).

Neuroleptic malignant syndrome (NMS) is a rare but potentially fatal adverse event associated with the use of antipsychotics. Although atypical antipsychotics were initially considered to carry no risk of NMS, reports have accumulated over time implicating them in NMS causation. Almost all atypical antipsychotics have been reported to be associated with NMS. The clinical profile of NMS caused by certain atypical antipsychotics such as clozapine has been reported to be considerably different from the NMS produced by typical antipsychotics, with diaphoresis encountered more commonly, and rigidity and tremor encountered less frequently. This article briefly discusses the evidence relating to the occurrence, presentation and management of NMS induced by atypical antipsychotics.

The aim of this study was to evaluate demographic, clinical, and treatment factors that may impact on neurological adverse effects in naive and quasi-naive children and adolescents treated with antipsychotics. This was a 1-year, multicenter, observational study of a naive and quasi-naive pediatric population receiving antipsychotic treatment. Two subanalyses were run using the subsample of subjects taking the 3 most used antipsychotics and the subsample of antipsychotic-naive subjects. Total dyskinesia score (DyskinesiaS) and total Parkinson score (ParkinsonS) were calculated from the Maryland Psychiatric Research Center Involuntary Movement Scale, total UKU-Cognition score was calculated from the UKU Side Effect Rating Scale. Risk factors for tardive dyskinesias (TDs) defined after Schooler-Kaine criteria were studied using a logistic regression. Two hundred sixty-five subjects (mean age, 14.4 [SD, 2.9] years) with different Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Axis I disorders were recruited. DyskinesiaS (P < 0.001) and ParkinsonS (P < 0.001) increased at 1-year follow-up. Risperidone was associated with higher increases in DyskinesiaS compared with quetiapine (P < 0.001). Higher increases in ParkinsonS were found with risperidone (P < 0.001) and olanzapine (P = 0.02) compared with quetiapine. Total UKU-Cognition Score decreased at follow-up. Findings were also significant when analyzing antipsychotic-naive subjects. Fifteen subjects (5.8%) fulfilled Schooler-Kane criteria for TD at follow-up. Younger age, history of psychotic symptoms, and higher cumulative exposure time were associated with TD at follow-up. Antipsychotics increased neurological adverse effects in a naive and quasi-naive pediatric population and should be carefully monitored. Risperidone presented higher scores in symptoms of dyskinesia and parkinsonism. Quetiapine was the antipsychotic with less neurological adverse effects. Younger subjects, psychosis, and

Full Text Available Atypical antipsychotics (AAP are the prevailing form of schizophrenia treatment today due to their low side effects and superior efficacy. Nevertheless, some issues still need to be addressed. First, there are still a large number of patients with treatment-resistant schizophrenia (TRS, which has led to a growing trend to resort to AAP polypharmacy with few side effects. Most clinical treatment guidelines recommend clozapine monotherapy in TRS, but around one third of schizophrenic patients fail to respond to clozapine. For these patients, with clozapine-resistant schizophrenia AAP polypharmacy is a common strategy with a continually growing evidence base. Second, AAP generally have great risks for developing metabolic syndrome, such as weight gain, abnormality in glucose, and lipid metabolism. These metabolic side effects have become huge stumbling blocks in today’s schizophrenia treatment that aims to improve patients’ quality of life as well as symptoms. The exact reasons why this particular syndrome occurs in patients treated with AAP is as yet unclear though factors such as interaction of AAP with neurotransmitter receptors, genetic pholymorphisms, type of AAPs, length of AAP use, and life style of schizophrenic patients that may contribute to its development. The present article aimed to review the evidence underlying these key issues and provide the most reasonable interpretations to expand the overall scope of antipsychotics usage.

Full Text Available The training of physicians in the past century was based primarily on responsibility and the chain-of-command. Those with the bulk of that responsibility in the fields of pediatrics and internal medicine were residents. Residents trained the medical students and supervised them carefully in caring for patients. Most attending physicians supervised their teams at arm's length, primarily serving as teachers of the finer points of diagnosis and treatment during set periods of the day or week with a perfunctory signature on write-ups or progress notes. Residents endeavored to protect the attending physician from being heavily involved unless they were unsure about a clinical problem. Before contacting the attending physician, a more senior resident would be called. Responsibility was the ultimate teacher. The introduction of diagnosis-related groups by the federal government dramatically changed the health care delivery system, placing greater emphasis on attending physician visibility in the medical record, ultimately resulting in more attending physician involvement in day-to-day care of patients in academic institutions. Without specified content in attending notes, hospital revenues would decline. Although always in charge technically, attending physicians increasingly have assumed the role once dominated by the resident. Using biographical experiences of more than 40 years, the author acknowledges and praises the educational role of responsibility in his own training and laments its declining role in today's students and house staff.

The research (study is epidemiological-clinical prospective, descriptive and analytical and it was conducted at University hospitals in Sarajevo, Tuzla and Mostar. Criteria for inclusion, non-inclusion and exclusion from the study were precisely defined as a mean for formation of sample. Based on this hypothesis were established, zero and alterative. According to zero hypothesis in the treatment of schizophrenia at University hospitals in FBiH new antipsychotic drugs are in use, small doses are proscribed (up to 20 mg, not more then one antipsychotic drug is used simultaneously, antipsychotics are administrated once a day and alongside with antipsychotics other medicaments are not co-administrated, especially antiparkinsons. The results of our study are showing that majority of patients are treated with classical antipsychotics. Minority of patients is treated with atypical neuroleptics like olanzapine, which is proscribed only in Sarajevo. Use of risperidone and ziprasidone is registered also only in Sarajevo, but only small number of patients is treated with these drugs. Most frequent antipsychotics were promazine and haloperidol. The range between minimal and maximal daily dose of promazine was from 50 to 450 mg/daily, and for haloperidol from 1 to 75 mg/daily. Above-mentioned drugs were administrated in an average from two to three times a day. Alongside with antipsychotics, other drugs were used. Most frequent was the use of biperidine in oral and parenteral formulation, as

In 2004, a consensus statement outlining recommended metabolic monitoring for patients prescribed second-generation antipsychotics (SGAs) was published. More than a decade later, suboptimal adherence rates to these recommendations continue to be reported, which could lead to long-term and costly complications. To define the prevalence of appropriately monitored Medicaid patients receiving care at federally qualified health centers (FQHCs) prescribed SGAs. This was a retrospective study examining electronic health record and Medicaid claims data to assess the rates of glucose and lipid monitoring for patients prescribed SGAs from January 2014 to August 2016 in a FQHC. Prescription and laboratory claims for patients receiving care at 4 FQHCs were reviewed. Descriptive statistics were used to evaluate the primary outcome. A total of 235 patients were included in the analysis. Patients initiated on SGA therapy (n = 92) had baseline glucose and lipid monitoring rates of 50% and 23%, respectively. The 3-month monitoring rates were 37% for glucose and 26% for lipids, whereas annual rates were 71% and 40%, respectively. Patients continuing SGA therapy (n = 143) had annual glucose and lipid monitoring rates of 67% and 44%. Medicaid patients at FQHCs initially prescribed SGAs have low baseline and 3-month metabolic monitoring, whereas annual monitoring was comparable to previously published studies. Adults receiving chronic care at a FQHC were more likely to receive glucose monitoring. Those with type 2 diabetes mellitus and/or hyperlipidemia were more likely to receive glucose and lipid monitoring.

Antipsychotic augmentation treatment with aripiprazole and quetiapine is approved for MDD patients and can achieve a high remission rate. This study aimed to examine how psychiatrists in Taiwan choose medications and how that choice is influenced by health insurance payments and administrative policy.Design: Descriptive study.Outcome measures: Eight questions about the choice of treatment strategy and atypical antipsychotics, and the reason to choose aripiprazole.Intervention: We designed an augmentation strategy questionnaire for psychiatrists whose patients had a poor response to antidepressants, and handed it out during the annual meeting of the Taiwanese Society of Psychiatry in October 2012. It included eight questions addressing the choice of treatment strategy and atypical antipsychotics, and the reason whether or not to choose aripiprazole as the augmentation antipsychotic.Results: Choosing antipsychotic augmentation therapy or switching to other antidepressant strategies for MDD patients with an inadequate response to antidepressants was common with a similar probability (76.1% vs 76.4%. The most frequently used antipsychotics were aripiprazole and quetiapine, however a substantial number of psychiatrists chose olanzapine, risperidone, and sulpiride.

Full Text Available BACKGROUND: Herb-drug interactions are an important issue in drug safety and clinical practice. The aim of this epidemiological study was to characterize associations of clinical outcomes with concomitant herbal and antipsychotic use in patients with schizophrenia. METHODS AND FINDINGS: In this retrospective, cross-sectional study, 1795 patients with schizophrenia who were randomly selected from 17 psychiatric hospitals in China were interviewed face-to-face using a structured questionnaire. Association analyses were conducted to examine correlates between Chinese medicine (CM use and demographic, clinical variables, antipsychotic medication mode, and clinical outcomes. The prevalence of concomitant CM and antipsychotic treatment was 36.4% [95% confidence interval (95% CI 34.2%-38.6%]. Patients using concomitant CM had a significantly greater chance of improved outcomes than non-CM use (61.1% vs. 34.3%, OR = 3.44, 95% CI 2.80-4.24. However, a small but significant number of patients treated concomitantly with CM had a greater risk of developing worse outcomes (7.2% vs. 4.4%, OR = 2.06, 95% CI 2.06-4.83. Significant predictors for concomitant CM treatment-associated outcomes were residence in urban areas, paranoid psychosis, and exceeding 3 months of CM use. Herbal medicine regimens containing Radix Bupleuri, Fructus Gardenia, Fructus Schisandrae, Radix Rehmanniae, Akebia Caulis, and Semen Plantaginis in concomitant use with quetiapine, clozapine, and olanzepine were associated with nearly 60% of the risk of adverse outcomes. CONCLUSIONS: Concomitant herbal and antipsychotic treatment could produce either beneficial or adverse clinical effects in schizophrenic population. Potential herb-drug pharmacokinetic interactions need to be further evaluated.

The challenge to achieve safe prescribing merits the adjective 'titanic'. The organisational and human errors leading to poor prescribing (e.g. underprescribing, overprescribing, misprescribing or medication errors) have parallels in the organisational and human errors that led to the loss of the Titanic 100 years ago this year. Prescribing can be adversely affected by communication failures, critical conditions, complacency, corner cutting, callowness and a lack of courage of conviction, all of which were also factors leading to the Titanic tragedy. These issues need to be addressed by a commitment to excellence, the final component of the 'Seven C's'. Optimal prescribing is dependent upon close communication and collaborative working between highly trained health professionals, whose role is to ensure maximum clinical effectiveness, whilst also protecting their patients from avoidable harm. Since humans are prone to error, and the environments in which they work are imperfect, it is not surprising that medication errors are common, occurring more often during the prescribing stage than during dispensing or administration. A commitment to excellence in prescribing includes a continued focus on lifelong learning (including interprofessional learning) in pharmacology and therapeutics. This should be accompanied by improvements in the clinical working environment of prescribers, and the encouragement of a strong safety culture (including reporting of adverse incidents as well as suspected adverse drug reactions whenever appropriate). Finally, members of the clinical team must be prepared to challenge each other, when necessary, to ensure that prescribing combines the highest likelihood of benefit with the lowest potential for harm. © 2012 The Author.

Finally, members of the clinical team must be prepared to challenge each other, when necessary, to ensure that prescribing combines the highest likelihood of benefit with the lowest potential for harm.

To quantify maternal use of atypical antipsychotics, typical antipsychotics, anticonvulsants, and lithium during pregnancy. Tennessee birth and death records were linked to Tennessee Medicaid data to conduct a retrospective cohort study of 296,817 women enrolled in Tennessee Medicaid throughout pregnancy who had a live birth or fetal death from 1985 to 2005. During the study time period, the adjusted rate of use of any study medication during pregnancy increased from nearly 14 to 31 per 1000 pregnancies (β = 0.08, 95% CI = 0.07, 0.09). Significant increases were reported in use of anticonvulsants alone among mothers with pain and other psychiatric disorders, atypical antipsychotics alone among mothers with bipolar disorders, schizophrenia, unipolar depressive disorders, and other psychiatric disorders, and more than one studied medication for mothers with epilepsy, pain disorders, bipolar disorders, unipolar depressive disorders, and other psychiatric disorders. Significant decreases were reported in use of lithium alone and typical antipsychotics alone for all clinically meaningful diagnosis groups. There was a substantial increase in use of atypical antipsychotics alone, anticonvulsants alone, and medications from multiple studied categories among Tennessee Medicaid-insured pregnant women during the study period. Further examination of the maternal and fetal consequences of exposure to these medications during pregnancy is warranted. Copyright © 2012 John Wiley & Sons, Ltd.

Data suggest that approximately 50,000 adults with learning disabilities (LDs) in England and Wales are currently prescribed antipsychotic medication. Illness in this population is common, including significant rates of challenging behaviour and mental illness, but there is particular concern over the use of antipsychotics prescribed for reasons other than the treatment of psychosis. Control of challenging behaviour is the primary reason why such medications are prescribed despite the absence of good evidence for any therapeutic effect for this purpose. To assess the feasibility of recruitment and retention and to explore non-efficacy-based barriers to a blinded antipsychotic medication withdrawal programme for adults with LDs without psychosis compared with treatment as usual. A secondary objective was to compare trial arms regarding clinical outcomes. A two-arm individually randomised double-blind placebo-controlled drug reduction trial. Recruitment was through community learning disability teams (CLDTs) in south Wales and south-west England. Adults with LDs who are prescribed risperidone for treatment of challenging behaviour with no known current psychosis or previous recurrence of psychosis following prior drug reduction. A double-blind drug reduction programme leading to full withdrawal within 6 months. Treatment in the intervention group was gradually reduced over a 6-month period and then maintained at the same level for a further 3 months, still under blind conditions. In the control group, the baseline level of medication was maintained throughout the 9-month period. The blind was broken at 9 months, following final data collection. Feasibility outcomes were (1) the number and proportion of general practices/CLDTs that progressed from initial approach to recruitment of participants and (2) the number and proportion of recruited participants who progressed through the various stages of the study. Trial arms were also compared regarding clinical outcomes

Background In many countries of the industrialised world second-generation (“atypical”) antipsychotics (SGAs) have become the first line drug treatment for people with schizophrenia. The question as to whether and if so how much the effects of the various SGAs differ is a matter of debate. In this review we examined how the efficacy and tolerability of risperidone differs from that of other SGAs. Objectives To evaluate the effects of risperidone compared with other atypical antipsychotics for people with schizophrenia and schizophrenia-like psychosis. Search methods 1. Electronic searching We searched the Cochrane Schizophrenia Group Trials Register (April 2007) which is based on regular searches of BIOSIS, CENTRAL, CINAHL, EMBASE, MEDLINE and PsycINFO. 2. Reference searching We inspected the references of all identified studies for more trials. 3. Personal contact We contacted the first author of each included study for missing information. 4. Drug companies We contacted the manufacturers of all atypical antipsychotics included for additional data. Selection criteria We included all randomised, blinded trials comparing oral risperidone with oral forms of amisulpride, aripiprazole, clozapine, olanzapine, quetiapine, sertindole, ziprasidone or zotepine in people with schizophrenia or schizophrenia-like psychosis. Data collection and analysis We extracted data independently. For dichotomous data we calculated risk ratio (RR) and their 95% confidence intervals (CI) on an intention-to-treat basis based on a random-effects model. We calculated numbers needed to treat/harm (NNT/NNH) where appropriate. For continuous data, we calculated mean differences (MD), again based on a random-effects model. Main results The review currently includes 45 blinded RCTs with 7760 participants. The number of RCTs available for each comparison varied: four studies compared risperidone with amisulpride, two with aripiprazole, 11 with clozapine, 23 with olanzapine, eleven with

To examine the effect of attending a medical school with an active policy on restricting gifts from representatives of pharmaceutical and device industries on subsequent prescribing behavior. Difference-in-differences approach. 14 US medical schools with an active gift restriction policy in place by 2004. Prescribing patterns in 2008 and 2009 of physicians attending one of the schools compared with physicians graduating from the same schools before the implementation of the policy, as well as a set of contemporary matched controls. Probability that a physician would prescribe a newly marketed medication over existing alternatives of three psychotropic classes: lisdexamfetamine among stimulants, paliperidone among antipsychotics, and desvenlafaxine among antidepressants. None of these medications represented radical breakthroughs in their respective classes. For two of the three medications examined, attending a medical school with an active gift restriction policy was associated with reduced prescribing of the newly marketed drug. Physicians who attended a medical school with an active conflict of interest policy were less likely to prescribe lisdexamfetamine over older stimulants (adjusted odds ratio 0.44, 95% confidence interval 0.22 to 0.88; P=0.02) and paliperidone over older antipsychotics (0.25, 0.07 to 0.85; P=0.03). A significant effect was not observed for desvenlafaxine (1.54, 0.79 to 3.03; P=0.20). Among cohorts of students who had a longer exposure to the policy or were exposed to more stringent policies, prescribing rates were further reduced. Exposure to a gift restriction policy during medical school was associated with reduced prescribing of two out of three newly introduced psychotropic medications.

While the prevalence of mental illness is higher in prisons than in the community, less is known about comparative rates of psychotropic medicine prescribing. This is the first study in a decade to determine the prevalence and patterns of psychotropic medication prescribing in prisons. It is also the first study to comprehensively adjust for age when making comparisons with the general population. Four East of England prisons, housing a total of 2222 men and 341 women were recruited to the study. On census days, clinical records were used to identify and collect data on all prisoners with current, valid prescriptions for hypnotic, anxiolytic, antipsychotic, antimanic, antidepressant and/or stimulant medication, as listed in chapters 4.1 to 4.4 of the British National Formulary. Data on 280,168 patients were obtained for comparison purposes from the Clinical Practice Research Datalink. After adjusting for age, rates of psychotropic prescribing in prison were 5.5 and 5.9 times higher than in community-based men and women, respectively. We also found marked differences in the individual psychotropic drugs prescribed in prison and community settings. Further work is necessary to determine whether psychotropic prescribing patterns in prison reflect an appropriate balance between managing mental illness, physical health risks and medication misuse.

Antipsychotic therapy can reduce severe symptoms of psychiatric disorders, however, data on school performance among children on such treatment are lacking. The objective was to explore school performance among children using antipsychotic drugs at the end of primary education. A cross-sectional study was conducted using the University Groningen pharmacy database linked to academic achievement scores at the end of primary school (Dutch Cito-test) obtained from Statistics Netherlands. Mean Cito-test scores and standard deviations were obtained for children on antipsychotic therapy and reference children, and statistically compared using analyses of covariance. In addition, differences in subgroups as boys versus girls, ethnicity, household income, and late starters (start date within 12 months of the Cito-test) versus early starters (start date > 12 months before the Cito-test) were tested. In all, data from 7994 children could be linked to Cito-test scores. At the time of the Cito-test, 45 (0.6 %) were on treatment with antipsychotics. Children using antipsychotics scored on average 3.6 points lower than the reference peer group (534.5 ± 9.5). Scores were different across gender and levels of household income (p starters were significantly higher than starters within 12 months (533.7 ± 1.7 vs. 524.1 ± 2.6). This first exploration showed that children on antipsychotic treatment have lower school performance compared to the reference peer group at the end of primary school. This was most noticeable for girls, but early starters were less affected than later starters. Due to the observational cross-sectional nature of this study, no causality can be inferred, but the results indicate that school performance should be closely monitored and causes of underperformance despite treatment warrants more research.

Iatrogenic hyperprolactinaemia (IHPRL) has been more frequently related to some antipsychotic drugs that provoke an intense blockade of dopamine D2 receptors. There is a wide variation in clinical practice, and perhaps some more awareness between clinicians is needed. Due to the high frequency of chronic treatment in severe mental patients, careful attention is recommended on the physical risk. IHPRL symptoms could be underestimated without routine examination. An intense scientific literature search was performed in order to draw up a multidisciplinary consensus, including different specialists of psychiatry, endocrinology, oncology and internal medicine, and looking for a consensus about clinical risk and detection of IHPRL following evidence-based medicine criteria levels (EBM I- IV). Short-term symptoms include amenorrhea, galactorrhoea, and sexual dysfunction with decrease of libido and erectile difficulties related to hypogonadism. Medium and long-term symptoms related to oestrogens are observed, including a decrease bone mass density, hypogonadism, early menopause, some types of cancer risk increase (breast and endometrial), cardiovascular risk increase, immune system disorders, lipids, and cognitive dysfunction. Prolactin level, gonadal hormones and vitamin D should be checked in all patients receiving antipsychotics at baseline although early symptoms (amenorrhea-galactorrhoea) may not be observed due to the risk of underestimating other delayed symptoms that may appear in the medium term. Routine examination of sexual dysfunction is recommended due to possible poor patient tolerance and low compliance. Special care is required in children and adolescents, as well as patients with PRL levels >50ng/ml (moderate hyperprolactinaemia). A possible prolactinoma should be investigated in patients with PRL levels >150ng/ml, with special attention to patients with breast/endometrial cancer history. Densitometry should be prescribed for males >50 years old

Full Text Available Schizophrenia is a psychiatry disorder accompanying by alteration of mind-set, perception, thought, and behavior. Symptom of schizophrenia can be positive symptom and negative symptom. The positive symptom often became a fear for the others, that is aggresiveness as violance, suicide, ang homicide. Aggresiveness divided in five category, that is impulsivity, affective instability, anxiety/hyperarousal, cognitive disorganization, predatory/planned aggression. Pharmacology theraphy is a choice in decreasing aggresiveness in schizophrenia. Atypical antipsychotic theraphy indicate higher effectivity and fewer side effect than conventional antipsychotic.

drug with more risk of abandoning due to adverse effects, followed by clozapine. Amisulpride, haloperidol and ziprasidone had favourable results as regards weight increase in several comparisons. Aripiprazole and paliperidone obtained a higher number of favourable results as regards sedation, and all the atypical drugs (except paliperidone) had a lower risk than the use of anti-parkinsonian drugs. Of the evidence from observational studies, it was found that, in subjects with risk factors for diabetes, such as age, hypertension, and dyslipidaemia, the initial treatment and current treatment with olanzapine, as well as current treatment with clozapine, may promote the development of this disease. Although it is imperative to prescribe an antipsychotic for treatment of the acute phase, the selection of the drug depends on the particular clinical condition of each patient and their collateral effects profile.

We identified four main thematic categories: patients' faith in antibiotics as medication for upper respiratory tract infections......; patient potential to influence a GP's decision to prescribe antibiotics for upper respiratory tract infections; impediments perceived by GPs in advocating clinically grounded antibiotic prescribing with their patients, and strategies applied in physician-patient negotiation about antibiotic prescribing...
Full Text Available The decision to vote and choosing among the candidates is an extremely important one with repercussions on everyday life by determining, in global mode, its quality for the whole society. Therefore the whole process by which the voter decides becomes a central concern. Prescribers, supposed to have a big influence on the electoral market, are a component of the microenvironment political organizations. These are people who occupy important positions that can influence the behavior of others. In the political environment, prescribers are known under the name of "opinion formers", "opinion leaders", "mediators" (Beciu, 2009 or "influencers" (Keller and Berry, 2003 Weimann, 1994. This paper aims to review the central opinions on what is the influence prescribers, opinion makers on voting behavior, voting and decisions on whether and how they act?

A recently published study in Pediatrics by Kaiser et al. (2014; Epub April 21, DOI: 10.1542/peds.2013-3171) reported that on average, over the past decade, children aged 3 to 17 were prescribed approximately 700,000 prescriptions for codeine-containing products each year in association with emergency department (ED) visits. Although, guidelines from the American Academy of Pediatrics issued warnings in 1997 and reaffirmed their concerns regarding the safety and effectiveness of codeine in 2006, it is still often prescribed for pain and cough associated with upper respiratory infection. With the impending rescheduling of hydrocodone combination products to Schedule II, physicians and mid-level prescribers may be compelled to prescribe codeine-containing products (e.g., with acetaminophen) due to reduced administrative burden and limits on Schedule II prescriptive authority for nurse practitioners and physician assistants in some states. This commentary expounds on the safety and effectiveness concerns of codeine, with a primary focus on patients in the ED setting.

Since the discovery of chlorpromazine (CPZ) in 1952, first-generation antipsychotics (FGAs) have revolutionized psychiatric care in terms of facilitating discharge from hospital and enabling large numbers of patients with severe mental illness (SMI) to be treated in the community. Second-generation antipsychotics (SGAs) ushered in a progressive shift from the paternalistic management of SMI symptoms to a patient-centered approach, which emphasized targets important to patients – psychosocial functioning, quality of life, and recovery. These drugs are no longer limited to specific Diagnostic and Statistical Manual of Mental Disorders (DSM) categories. Evidence indicates that SGAs show an improved safety and tolerability profile compared with FGAs. The incidence of treatment-emergent extrapyramidal side effects is lower, and there is less impairment of cognitive function and treatment-related negative symptoms. However, treatment with SGAs has been associated with a wide range of untoward effects, among which treatment-emergent weight gain and metabolic abnormalities are of notable concern. The present clinical review aims to summarize the safety and tolerability profile of selected FGAs and SGAs and to link treatment-related adverse effects to the pharmacodynamic profile of each drug. Evidence, predominantly derived from systematic reviews, meta-analyses, and clinical trials of the drugs amisulpride, aripiprazole, asenapine, brexpiprazole, cariprazine, clozapine, iloperidone, lurasidone, olanzapine, paliperidone, quetiapine, risperidone, sertindole, ziprasidone, CPZ, haloperidol, loxapine, and perphenazine, is summarized. In addition, the safety and tolerability profiles of antipsychotics are discussed in the context of the “behavioral toxicity” conceptual framework, which considers the longitudinal course and the clinical and therapeutic consequences of treatment-emergent side effects. In SMI, SGAs with safer metabolic profiles should ideally be prescribed
Full Text Available Marek J Just Department of General and Endocrine Surgery, Piekary Medical Centre, Piekary Slaskie, Poland Abstract: Human sexuality is contingent upon many biological and psychological factors. Such factors include sexual drive (libido, physiological arousal (lubrication/erection, orgasm, and ejaculation, as well as maintaining normal menstrual cycle. The assessment of sexual dysfunction can be difficult due to the intimate nature of the problem and patients’ unwillingness to discuss it. Also, the problem of dysfunction is often overlooked by doctors. Atypical antipsychotic treatment is a key component of mental disorders’ treatment algorithms recommended by the National Institute of Health and Clinical Excellence, the American Psychiatric Association, and the British Society for Psychopharmacology. The relationship between atypical antipsychotic drugs and sexual dysfunction is mediated in part by antipsychotic blockade of pituitary dopamine D2 receptors increasing prolactin secretion, although direct correlations have not been established between raised prolactin levels and clinical symptoms. Variety of mechanisms are likely to contribute to antipsychotic-related sexual dysfunction, including hyperprolactinemia, sedation, and antagonism of a number of neurotransmitter receptors (α-adrenergic, dopaminergic, histaminic, and muscarinic. Maintaining normal sexual function in people treated for mental disorders can affect their quality of life, mood, self-esteem, attitude toward taking medication, and compliance during therapy.

Full Text Available Cognitive enhancement has become an important target for drug therapies in schizophrenia. Treatment development in this area requires assessment approaches that are sensitive to procognitive effects of antipsychotic and adjunctive treatments. Ideally, new treatments will have translational characteristics for parallel human and animal research. Previous studies of antipsychotic effects on cognition have relied primarily on paper-and-pencil neuropsychological testing. No study has directly compared neurophysiological biomarkers and neuropsychological testing as strategies for assessing cognitive effects of antipsychotic treatment early in the course of schizophrenia. Anti psychotic-naive patients with schizophrenia were tested before treatment with risperidone and again 6 weeks later. Matched healthy participants were tested over a similar time period. Test-retest reliability, effect sizes of within-subject change, and multivariate/univariate analysis of variance were used to compare 3 neurophysiological tests (visually guided saccade, memory-guided saccade, and antisaccade with neuropsychological tests covering 4 cognitive domains (executive function, attention, memory, and manual motor function. While both measurement approaches showed robust neurocognitive impairments in patients prior to risperidone treatment, oculomotor biomarkers were more sensitive to treatment-related effects on neurocognitive function than traditional neuropsychological measures. Further, unlike the pattern of modest generalized cognitive improvement suggested by neuropsychological measures, the oculomotor findings revealed a mixed pattern of beneficial and adverse treatment related effects. These findings warrant further investigation regarding the utility of neurophysiological biomarkers for assessing cognitive outcomes of antipsychotic treatment in clinical trials and in early-phase drug development.

Generic atypical antipsychotic drugs offer health authorities opportunities for considerable savings. However, schizophrenia and bipolar disorders are complex diseases that require tailored treatments. Consequently, generally there have been limited demand-side measures by health authorities to encourage the preferential prescribing of generics. This is unlike the situation with hypertension, hypercholaesterolaemia or acid-related stomach disorders.The objectives of this study were to compare the effect of the limited demand-side measures in Western European countries and regions on the subsequent prescribing of risperidone following generics; to utilise the findings to provide future guidance to health authorities; and where possible, to investigate the utilisation of generic versus originator risperidone and the prices for generic risperidone. Principally, this was a segmented regression analysis of retrospective time-series data of the effect of the various initiatives in Belgium, Ireland, Scotland and Sweden following the introduction of generic risperidone. The study included patients prescribed at least one atypical antipsychotic drug up to 20 months before and up to 20 months after generic risperidone. In addition, retrospective observational studies were carried out in Austria and Spain (Catalonia) from 2005 to 2011 as well as one English primary care organisation (Bury Primary Care Trust (PCT)). There was a consistent steady reduction in risperidone as a percentage of total selected atypical antipsychotic utilisation following generics. A similar pattern was seen in Austria and Spain, with stable utilisation in one English PCT. However, there was considerable variation in the utilisation of generic risperidone, ranging from 98% of total risperidone in Scotland to only 14% in Ireland. Similarly, the price of generic risperidone varied considerably. In Scotland, generic risperidone was only 16% of pre-patent loss prices versus 72% in Ireland. Consistent

Clinical decision support (CDS) in e-prescribing can improve safety by alerting potential errors, but introduces new sources of risk. Automation bias (AB) occurs when users over-rely on CDS, reducing vigilance in information seeking and processing. Evidence of AB has been found in other clinical tasks, but has not yet been tested with e-prescribing. This study tests for the presence of AB in e-prescribing and the impact of task complexity and interruptions on AB. One hundred and twenty students in the final two years of a medical degree prescribed medicines for nine clinical scenarios using a simulated e-prescribing system. Quality of CDS (correct, incorrect and no CDS) and task complexity (low, low + interruption and high) were varied between conditions. Omission errors (failure to detect prescribing errors) and commission errors (acceptance of false positive alerts) were measured. Compared to scenarios with no CDS, correct CDS reduced omission errors by 38.3% (p < .0001, n = 120), 46.6% (p < .0001, n = 70), and 39.2% (p < .0001, n = 120) for low, low + interrupt and high complexity scenarios respectively. Incorrect CDS increased omission errors by 33.3% (p < .0001, n = 120), 24.5% (p < .009, n = 82), and 26.7% (p < .0001, n = 120). Participants made commission errors, 65.8% (p < .0001, n = 120), 53.5% (p < .0001, n = 82), and 51.7% (p < .0001, n = 120). Task complexity and interruptions had no impact on AB. This study found evidence of AB omission and commission errors in e-prescribing. Verification of CDS alerts is key to avoiding AB errors. However, interventions focused on this have had limited success to date. Clinicians should remain vigilant to the risks of CDS failures and verify CDS.
The neurotransmission mediated by the excitatory amino acids (EAA) glutamate (GLU) and aspartate is of interest to the pharmacotherapy of psychosis due to its role in neurodevelopment and neurotoxicity, its complex interactions with dopaminergic and other neurotransmitter systems and its pivotal importance in recent models of schizophrenia. Accumulating evidence indicates that modulation of glutamatergic neurotransmission may play an important role in the mechanisms of action of atypical antipsychotic drugs. The principles of the phencyclidine (PCP) model of schizophrenia suggest that conventional neuroleptics cannot counteract all aspects of schizophrenia symptomatology, while a more favorable outcome, including anti-negative and cognitive symptoms effects, would be expected with the use of treatment modalities targeting glutamatergic neurotransmission. Clozapine and other presently used atypical antipsychotics differ from conventional neuroleptics in the way they affect various aspects of glutamatergic receptors function. In this context, a specific hypothesis suggesting an agonistic role of clozapine at the N-methyl-D-aspartate (NMDA) subtype of GLU receptors has been postulated. Furthermore, the results of the first generation of clinical trials with glycine (GLY) site agonists of the NMDA receptor in schizophrenia suggest that this type of compounds (1) have efficacy and side effects profiles different than those of conventional neuroleptics and (2) differ in their synergic effects when used in addition to conventional neuroleptics versus clozapine and possibly additional atypical antipsychotics. These findings (1) bring further support to the hypothesis that glutamatergic effects may play an important role in the mechanism of action of atypical antipsychotics, (2) help explain the unique clinical profile of clozapine, and (3) suggest that GLY site agonists of the NMDA receptor may represent a new class of atypical antipsychotic medication.

To determine the indications of long-acting antipsychotic injection and what its effectiveness and safety in adult patients with schizophrenia during the treatment maintenance phase. A clinical practice guideline was elaborated under the parameters of the Methodological Guide of the Ministerio de Salud y Protección Social to identify, synthesize and evaluate the evidence and make recommendations about the treatment and follow-up of adult patients with schizophrenia. The evidence of NICE guide 82 was adopted and updated. The evidence was presented to the Guideline Developing Group and recommendations, employing the GRADE system, were produced. The literature review shows that the evidence has moderate to low quality. 8 articles were used. The risk of relapse was lower with depot risperidone and paliperidone palmitate when compared with placebo. For the risk of hospitalizations comparing depot antipsychotics (APD) versus oral AP, the result is inconclusive. Globally the second-generation APD had a lower risk of discontinuation when compared with placebo. The second generation AP had higher risk of extrapyramidal syndromes than placebo, as in the use of antiparkinsonian. The comparison of second-generation AP injections versus placebo showed an increased risk of early weight gain. The use of depot antipsychotics in the maintenance phase of adult patients diagnosed with schizophrenia is recommended if there is no adherence to oral antipsychotics as the patient's preference. It is not recommended depot antipsychotics in the acute phase of schizophrenia in adults. Copyright © 2014 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España. All rights reserved.

Despite known metabolic effects of second-generation antipsychotics (SGAs) on children and adolescents, comparative effects in youth with different diagnoses remain underreported. We compared differences in metabolic changes three months after starting treatment with SGAs in youth with bipolar disorder and with other psychotic and nonpsychotic disorders. Weight and metabolic differences among diagnostic groups before and three months after starting treatment with SGAs were compared in a naturalistic cohort of children and adolescents (14.9 +/- 3.0 years) diagnosed with bipolar disorder (n = 31), other psychotic disorders (n = 29), and other nonpsychotic disorders (n = 30), with no (35.6%) or very little (6.6 +/- 9.0 days) previous exposure to antipsychotics. Composite measurements of significant weight gain [weight increase > or = 5% at three months or increase > or = 0.5 in body mass index (BMI) z-score] and 'risk for adverse health outcome' (> or = 95(th) BMI percentile, or > or = 85(th) BMI percentile plus presence of one other obesity-related complication) were included. SGAs (risperidone, olanzapine, and quetiapine) were prescribed in comparable proportion among groups. Baseline weight and metabolic indices were not significantly different among diagnoses. Three months after starting treatment with SGAs, more than 70% patients had significant weight gain, BMI z-score increased in all diagnostic groups (p or = 1 obesity-related complication at follow-up. There are early weight gain and metabolic changes across diagnoses in youth treated with SGAs.

Although antipsychotics are widely prescribed, their effect of on improving poor illness insight in schizophrenia has seldom been investigated and therefore remains uncertain. This paper examines the effects of low dose haloperidol, amisulpride, olanzapine, quetiapine, and ziprasidone on insight in first-episode schizophrenia, schizoaffective disorder, or schizophreniform disorder. The effects of five antipsychotic drugs in first episode psychosis on insight were compared in a large scale open randomized controlled trial conducted in 14 European countries: the European First-Episode Schizophrenia Trial (EUFEST). Patients with at least minimal impairments in insight were included in the present study (n=455). Insight was assessed with item G12 of the Positive and Negative Syndrome Scale (PANSS), administered at baseline and at 1, 3, 6, 9, and 12 months after randomization. The use of antipsychotics was associated with clear improvements in insight over and above improvements in other symptoms. This effect was most pronounced in the first three months of treatment, with quetiapine being significantly less effective than other drugs. Effects of spontaneous improvement cannot be ruled out due to the lack of a placebo control group, although such a large spontaneous improvement of insight would seem unlikely.

Full Text Available Introduction: Depressive symptoms may occur in all stages of schizophrenia disorder. Clozapine is the only antipsychotic that has been demonstrated superior efficacy in schizophrenia and suicidal ideation. The aim of this study is to evaluate depressive symptoms in patients with schizophrenia treated with clozapine and to compare with treated with other atypical antipsychotics.Methods: A cross-sectional descriptive study was carried out on patients with schizophrenia according to DSM-IV-TR between December 2012 and May 2013. All participants were evaluated for demographic characteristics and points of Brief Psychiatric Rating Scale, Positive, Negative Syndrome Scale, and Calgary Depression Scale for Schizophrenia.Results: A total 23.6% (n = 13 patients treated with clozapine, while 76.4% (n = 42 patients were treated with other antipsychotic drugs. 23.1% (n = 3 of patients taking clozapine were women, 76.9% (n = 10 were male. The mean age of patients treated with clozapine was 43.0 ± 11.2. The level of depression of patients treated with clozapine was 15.4% (n = 2. No statistically significant difference was found between patients between treated with clozapine and other antipsychotics regarding age, sex, marital status, education years, work history, age at onset of disease, depression and history of suicide attemptConclusion: As a result of this study it is found that clozapine did not effect on the level of depression in patients with schizophrenia, and depression level of patients with schizophrenia treated with clozapine had no difference from patients treated with other antipsychotics.

Despite being a common admitting diagnosis, there is very little published literature on medication management in hospice patients admitted with a diagnosis of failure to thrive or debility. The purpose of this study was to describe medication prescribing practices in hospice patients with either of these primary diagnoses by characterizing prescribed medications by name and by pharmaceutical class, and determining whether the patient or the hospice organization provided each medication. A retrospective review of a patient information database compiled by a national hospice organization was conducted. Patients were included in this retrospective study if they were admitted to hospice care with a primary diagnosis of failure to thrive or debility, and if they were admitted on or after 1 January 2010, and discharged by death on or before 31 December 2010. Overall 293 patients and 6181 medication entries were evaluated. The most commonly prescribed drugs were acetaminophen, lorazepam, morphine, atropine, prochlorperazine, haloperidol, docusate, aspirin, and bisacodyl. The most commonly prescribed pharmacological classes were opioid and non-opioid analgesics, anxiolytics, anticholinergics, antihypertensives, laxatives, antidepressants, and supplements. The hospice organization provided over 90% of prescriptions for analgesics, antipsychotics, anticholinergics, and anxiolytics, and these medications were discontinued before death in less than 5% of patients. Recognized clinical components of failure to thrive syndrome include cognitive impairment, malnutrition, and depression. The hospice organization provided 80% of antidepressants, but infrequently provided appetite stimulants and drugs treating dementia. The most commonly provided drugs were those used for symptoms associated with most end-stage diseases.
Full Text Available There is a considerable disparity between clinical practice and recommendations based on meta-analyses of antipsychotic polypharmacy in clozapine resistant schizophrenia. For this reason, we investigated the clinical response to reducing the use olanzapine that had been previously added on clozapine treatment among seriously ill hospitalized patients. In a randomized controlled trial with crossover design, we studied volunteer patients (N = 15 who had olanzapine added on to clozapine in a state mental hospital. Clozapine monotherapy was just as effective as clozapine-olanzapine therapy, according to results from Clinical Global Impression Scale and Global Assessment of Functioning as primary outcome measures. Polypharmacy is widely used in treating schizophrenia, and usually, add-on medications are started because of worsening of the clinical state. A major confounding feature of these add-ons is whether observed improvements are caused by the medication or explained by the natural fluctuating course of the disorder. The present study, in spite of its small size, indicates the necessity of reconsidering the value of polypharmacy in treating schizophrenia.

Poor medication adherence contributes to negative treatment response, symptom relapse, and hospitalizations in schizophrenia. Many health plans use claims-based measures like medication possession ratios or proportion of days covered (PDC) to measure patient adherence to antipsychotics. Classifying patients solely on the basis of a single average PDC measure, however, may mask clinically meaningful variations over time in how patients arrive at an average PDC level. To model patterns of medication adherence evolving over time for patients with schizophrenia who initiated treatment with an oral atypical antipsychotic and, based on these patterns, to identify groups of patients with different adherence behaviors. We analyzed health insurance claims for patients aged ≥ 18 years with schizophrenia and newly prescribed oral atypical antipsychotics in 2007-2013 from 3 U.S. insurance claims databases: Truven MarketScan (Medicaid and commercial) and Humana (Medicare). Group-based trajectory modeling (GBTM) was used to stratify patients into groups with distinct trends in adherence and to estimate trends for each group. The response variable was the probability of adherence (defined as PDC ≥ 80%) in each 30-day period after the patient initiated antipsychotic therapy. GBTM proceeds from the premise that there are multiple distinct adherence groups. Patient demographics, health status characteristics, and health care resource use metrics were used to identify differences in patient populations across adherence trajectory groups. Among the 29,607 patients who met the inclusion criteria, 6 distinct adherence trajectory groups emerged from the data: adherent (33%); gradual discontinuation after 3 months (15%), 6 months (7%), and 9 months (5%); stop-start after 6 months (15%); and immediate discontinuation (25%). Compared to patients 18-24 years of age in the adherent group, patients displaying a stop-start pattern after 6 months had greater odds of having a history of drug

Advancing age entails specific treatment modalities for patients with schizophrenia. The choice of appropriate antipsychotic therapy (AP) and the monitoring of treatment is a major challenge. However, little is known about the real-world prescribing practices of psychiatrists for elderly schizophrenia patients. The aim of this study was to assess prescribing practices and treatment monitoring in elderly schizophrenia patients and whether socio-professional psychiatrists' characteristics are related to their practices. We contacted by mail 190 psychiatrists to take part in an observational survey of their AP prescribing practices for elderly (aged over 65) schizophrenia patients. The response rate was 44.2%, and of the psychiatrists who replied 75% were treating elderly schizophrenia patients. A second-generation AP (SGAP) was prescribed as first-line of treatment by 87.7% of the psychiatrists. The most frequently used SGAPs were risperidone and olanzapine (respectively preferred by 54.4% and 19.3% of the psychiatrists taking part). At the beginning of treatment, 91.1% of the psychiatrists prescribed a lower dose than for middle-aged patients. Of the psychiatrists taking part, 64.9% prescribed monotherapy; and among these psychiatrists, 65% cited insufficient control of the disease as the reason for their choice, while 48.7% of those who elected not to prescribe combined AP did so in order to limit the side-effects. Of the psychiatrists taking part, 54.4% prescribed long-acting injectable AP (LAAP); better therapeutic compliance and alliance was the main argument in the choice of LAAP given by the psychiatrists taking part who prescribed the drug, whereas the absence of indications and problems of tolerance were arguments against for those who did not. "Personal experience" emerged as the governing factor in the choice of AP. The AP side-effect profile was the main criterion of choice of the AP agent for 3.5% of the psychiatrists taking part, and the most frequently
Full Text Available Prevalence of generalised anxiety disorders is widespread in Great Britain. Previous small-scale research has shown variations in minor tranquiliser prescribing, identifying several potential predictors of prescribing volume. Objective: This study aimed to investigate the relationship between general practice minor tranquiliser prescribing rates and practice population and general practice characteristics for all general practices in England.Methods: Multiple regression analysis of minor tranquiliser prescribing volumes during 2004/2005 for 8,291 English general practices with general practice and population variables obtained from the General Medical Services (GMS statistics, Quality and Outcomes Framework (QOF, 2001 Census and 2004 Index of Multiple Deprivation (IMD. Results: The highest rates of minor tranquiliser prescribing were in areas with the greatest local deprivation while general practices situated in areas with larger proportions of residents of black ethnic origin had lower rates of prescribing. Other predictors of increased prescribing were general practices with older general practitioners and general practices with older registered practice populations.Conclusion: Our findings show that there is wide variation of minor tranquilisers prescribing across England which has implications regarding access to treatment and inequity of service provision. Future research should determine the barriers to equitable prescribing amongst general practices serving larger populations of black ethnic origin.

A variety of programming techniques and methods of training have been employed to change physician behavior. Didactic continuing medical education lectures and clinical guidelines have had minimal impact, although endorsement of national professional guidelines by local opinion leaders appears to have a positive influence on the impact of professional guidelines. Interactive, hands-on workshops, performance reporting, and peer/patient feedback are also effective. Changing prescribing habits has been equally difficult. Drug utilization letters involving both pharmacist and physician have more impact than do letters sent only to the physician. Academic detailing, when properly executed, has been consistently effective. When combined with these strategies, closed formularies become a powerful tool in changing prescribing behavior.

In this review, we conclude that cognitive impairments are as important as positive and negative symptoms in the clinical assessment and management of patients with schizophrenia. This is not a comprehensive review, considering that the new Measurement And Treatment Research to Improve Cognition in Schizophrenia (MATRICS) model will soon provide valuable data. It is however a product of the collective efforts of a French Canadian clinical research team that proposes a synthesis of data of pragmatic interest to clinicians. Medication with improved safety and cognition profile, gene-rally lead to better outcomes by facilitating compliance with drug regimens and rehabilitation programs. In addition, measures of attention and executive function (EF) appear to improve with novel antipsychotics when compared to traditional neuroleptics. Nevertheless, evaluating cognitive performance is not a routine procedure outside the domain of research. For example, procedural learning (PL) -- an important measure of cognitive function -- refers to cognitive and motor learning processes in which execution strategies cannot be explicitly described (ie learning by doing). These actions or procedures are then progressively learned through trial and error until automation of optimal performance is established. Procedural learning is rarely assessed in clinical practice. Inconsistent findings regarding the effects of neuroleptic drugs on PL have been reported. Trials using acute administration of chlorpromazine in normal subjects induced PL deficits, suggesting the direct effect of neuroleptics, presumably via a D(2) dopamine blockade in the striatum. In a recent study by our group, schizophrenia patients, divided into three groups according to their pharmacological treatment (haloperidol, clozapine and risperidone) were compared to normal controls on two PL tasks; a visuomotor learning task (mirror drawing) and a problem solving learning task (Tower of Toronto). No deficits were detected

Introduction: \\ud Clinicians typically use findings from cohort studies to objectively inform judgements regarding the potential (dis)advantages of prescribing a new prosthetic device. However, before finalising prescription a clinician will typically ask a patient to 'try out' a change of prosthetic device while the patient is at the clinic. Observed differences in gait when using the new device should be the result of the device’s mechanical function, but could also conceivably be due to pa...

Full Text Available Abstract Background Over 300 therapies have been proposed for premenstrual syndrome. To date there has been only one survey conducted in the UK of PMS treatments prescribed by GPs, a questionnaire-based study by the National Association of Premenstrual Syndrome in 1989. Since then, selective serotonin re-uptake inhibitors have been licensed for severe PMS/PMDD, and governmental recommendations to reduce the dosage of vitamin B6 (the first choice over-the-counter treatment for many women with PMS have been made. This study investigates the annual rates of diagnoses and prescribing patterns for premenstrual syndrome (1993–1998 within a computerised general practitioner database. Methods Retrospective survey of prescribing data for premenstrual syndrome between 1993–1998 using the General Practice Research Database for the West Midlands Region which contains information on 282,600 female patients Results Overall the proportion of women with a prescription-linked diagnosis of premenstrual syndrome has halved over the five years. Progestogens including progesterone were the most commonly recorded treatment for premenstrual syndrome during the whole study period accounting for over 40% of all prescriptions. Selective serotonin-reuptake inhibitors accounted for only 2% of the prescriptions in 1993 but rose to over 16% by 1998, becoming the second most commonly recorded treatment. Vitamin B6 accounted for 22% of the prescriptions in 1993 but dropped markedly between 1997 and 1998 to 11%. Conclusions This study shows a yearly decrease in the number of prescriptions linked to diagnoses for premenstrual syndrome. Progestogens including progesterone, is the most widely prescribed treatment for premenstrual syndrome despite the lack of evidence demonstrating their efficacy.

Psychotropic drug prescribing for children and adolescents is frequently off-label and has increased over time and can be controversial. Psychotropic prescribing in two large UK medium secure units for young people has been studied. A total of 89 patients were included, 64% being aged less than 18 years. A total of 137 of 202 (67.8%) of prescriptions were off-label. The most common reasons for a prescription being off-label were the indication (N = 103) and the patient's age (N = 41). The main classes of drugs involved were antipsychotics (N = 59), antiepileptics as mood stabilisers (N = 22), anticholinergics and hyoscine (N = 15) and antidepressants (N = 11). Aggression (N = 48) and post-traumatic stress disorder (N = 30) were the most common off-label indications. Some antidepressant prescriptions were contrary to advice of the Committee on Safety of Medicines (CSM). Meta-analyses or randomised controlled trials supported 27% of off-label prescriptions, with lesser quality studies supporting a further 29.2% and expert opinion 38.7%, whereas for 5.1% no evidence could be found. Prescribers tended to over-estimate the level of evidence from clinical trials or extrapolated from findings in adults. They often quoted their own experience rather than expert sources to justify their prescribing practice. It is important that prescribers are fully aware of the quality of experimental data and the risk-benefit ratio when prescribing off-label for young persons. If the evidence base is limited, it is particularly important to provide information about the risks and benefits of the treatment to the patient/relatives. A second opinion may be helpful. Both target symptoms and side effects should be monitored and regularly reviewed.

Excessive opioid prescribing is common after curative-intent surgery, but little is known about what factors influence prescribing behaviors among surgeons. To identify targets for intervention, we performed a qualitative study of opioid prescribing after curative-intent surgery using the Theoretical Domains Framework, a well-established implementation science method for identifying factors influencing healthcare provider behavior. Prior to data collection, we constructed a semi-structured interview guide to explore decision making for opioid prescribing. We then conducted interviews with surgical oncology providers at a single comprehensive cancer center. Interviews were recorded, transcribed verbatim, then independently coded by two investigators using the Theoretical Domains Framework to identify theoretical domains relevant to opioid prescribing. Relevant domains were then linked to behavior models to select targeted interventions likely to improve opioid prescribing. Twenty-one subjects were interviewed from November 2016 to May 2017, including attending surgeons, resident surgeons, physician assistants, and nurses. Five theoretical domains emerged as relevant to opioid prescribing: environmental context and resources; social influences; beliefs about consequences; social/professional role and identity; and goals. Using these domains, three interventions were identified as likely to change opioid prescribing behavior: (1) enablement (deploy nurses during preoperative visits to counsel patients on opioid use); (2) environmental restructuring (provide on-screen prompts with normative data on the quantity of opioid prescribed); and (3) education (provide prescribing guidelines). Key determinants of opioid prescribing behavior after curative-intent surgery include environmental and social factors. Interventions targeting these factors are likely to improve opioid prescribing in surgical oncology.

Background: Akathisia continues to be a significant challenge in current neurological and psychiatric practice. Prompt and accurate detection is often difficult and there is a lack of consensus concerning the neurobiological basis of akathisia. No definitive treatment has been established for akathisia despite numerous preclinical and clinical studies. Method: We reviewed antipsychotic-induced akathisia including its clinical presentation, proposed underlying pathophysiology, current and under investigation therapeutic strategies. Conclusion: Despite the initial promise that second generation antipsychotics would be devoid of akathisia effects, this has not been confirmed. Currently, there are limited therapeutic options for the clinical practice and the evidence supporting the most widely used treatments (beta blockers, anticholinergic drugs) is still absent or inconsistent.

To determine the effectiveness and security of the antipsychotics available for the management of adult patients with schizophrenia in the maintenance phase. To develop recommendations of treatment for the maintenance phase of the disease. A clinical practice guideline was elaborated under the parameters of the Methodological Guide of the Ministerio de Salud y Protección Social to identify, synthesize and evaluate the evidence and make recommendations about the treatment and follow-up of adult patients with schizophrenia. The evidence of NICE guide 82 was adopted and updated. The evidence was presented to the Guideline Developing Group and recommendations, employing the GRADE system, were produced. 18 studies were included to evaluate the effectiveness and / or safety of different antipsychotic drugs first and second generation. Overall, antipsychotics (AP) showed superiority over placebo in relapse rate over 12 months (RR 0.59 95% CI 0.42, 0.82) and hospitalization rate over 24 months of follow-up (RR 0.38 95% 0.27, 0.55); its use is associated with increased risk of treatment dropout (RR 0.53 95% CI 0.46, 0.61) and adverse events such as weight gain, dystonia, extrapyramidal symptoms and sedation. There was no difference in the outcome of re hospitalizations, comparisons on quality of life, negative symptoms or weight gain between AP first and second generation. Continuous or standard dose regimens appear to be superior to intermittent or low doses in reducing the risk of abandonment of treatment regimes. Adult patients diagnosed with schizophrenia should receive maintenance treatment with antipsychotics. The medication of choice will depend on the management of the acute phase, the patient's tolerance to it and the presentation of adverse events. Copyright © 2014 Asociación Colombiana de Psiquiatría.

The present study analyzes the role of neurocognitive assessment instruments in the detection of the contribution of antipsychotic treatment to cognitive functioning. Recently, a panel of experts suggested six main domains (working memory; attention/vigilance; verbal/visual learning and memory; reasoning and problem solving; speed of processing) implicated in schizophrenia-related cognitive deficits, which serve as a theoretical base for creation of real-time computerized neurocognitive batteries. The high sensitivity of computerized neuropsychological testing is based on their ability to adopt the reaction time (RT) paradigm for the assessment of brain function in a real-time regime. This testing is highly relevant for the monitoring of the cognitive effects of antipsychotics. Computerized assessment assists in the identification of state- and trait-related cognitive impairments. The optimal real-time computerized neurocognitive battery should composite balance between broad and narrow coverage of cognitive domains relevant to the beneficial effects of antipsychotics and will enable better planning of treatment and rehabilitation programs.

Assess the cost-effectiveness of the antipsychotics for treatment of schizophrenia. A five-year Markov model was built form patients with schizophrenia on the stage of maintenance. Costs were taken from the perspective of the Colombian health care system (Sistema General de Seguridad Social en Salud). The effectiveness was measured in years of life under the same maintenance plan. The Markov model indicated clozapine as the as the most cost-effective alternative between the first line antipsychotics and haloperidol is it when comparing other antipsychotics. Clozapine it's the cost-effectiveness strategy among the first line of antipsychotics and haloperidol is it among the other antipsychotics. Strategies prioritizing the use of cost-effective antipsychotics could improve the resources allocation in the Colombian health care system. Copyright © 2014 Asociación Colombiana de Psiquiatría.

Inappropriate prescribing is highly prevalent in older people and is a major healthcare concern because of its association with negative healthcare outcomes including adverse drug events, related morbidity and hospitalization. With changing population demographics resulting in increasing proportions of older people worldwide, improving the quality and safety of prescribing in older people poses a global challenge. To date a number of different strategies have been used to identify potentially inappropriate prescribing in older people. Over the last two decades, a number of criteria have been published to assist prescribers in detecting inappropriate prescribing, the majority of which have been explicit sets of criteria, though some are implicit. The majority of these prescribing indicators pertain to overprescribing and misprescribing, with only a minority focussing on the underprescribing of indicated medicines. Additional interventions to optimize prescribing in older people include comprehensive geriatric assessment, clinical pharmacist review, and education of prescribers as well as computerized prescribing with clinical decision support systems. In this review, we describe the inappropriate prescribing detection tools or criteria most frequently cited in the literature and examine their role in preventing inappropriate prescribing and other related healthcare outcomes. We also discuss other measures commonly used in the detection and prevention of inappropriate prescribing in older people and the evidence supporting their use and their application in everyday clinical practice.

Guidelines for the treatment of psychoses recommend antipsychotic monotherapy. However, the rate of antipsychotic polytherapy has increased over the last decade, reaching up to 60% in some settings. Studies evaluating the costs and impact of antipsychotic polytherapy in the health system are scarce. To estimate the costs of antipsychotic polytherapy and its impact on public health costs in a sample of subjects with psychotic disorders living in residential facilities in the city of Sao Paulo, Brazil. A cross-sectional study that used a bottom-up approach for collecting costs data in a public health provider's perspective. Subjects with psychosis living in 20 fully-staffed residential facilities in the city of Sao Paulo were assessed for clinical and psychosocial profile, severity of symptoms, quality of life, use of health services and pharmacological treatment. The impact of polytherapy on total direct costs was evaluated. 147 subjects were included, 134 used antipsychotics regularly and 38% were in use of antipsychotic polytherapy. There were no significant differences in clinical and psychosocial characteristics between polytherapy and monotherapy groups. Four variables explained 30% of direct costs: the number of antipsychotics, location of the residential facility, time living in the facility and use of olanzapine. The costs of antipsychotics corresponded to 94.4% of the total psychotropic costs and to 49.5% of all health services use when excluding accommodation costs. Olanzapine costs corresponded to 51% of all psychotropic costs. Antipsychotic polytherapy is a huge economic burden to public health service, despite the lack of evidence supporting this practice. Great variations on antipsychotic costs explicit the need of establishing protocols for rational antipsychotic prescriptions and consequently optimising resource allocation. Cost-effectiveness studies are necessary to estimate the best value for money among antipsychotics, especially in low and middle

Early recognition and treatment of agitated patients is essential to avoid violence in the psychiatric emergency department (ED). Antipsychotics have established efficacy in managing agitation, yet little is known about how the choice of initial antipsychotic impacts time to repeat use and length of stay (LOS) in the psychiatric ED. To describe the impact of initial antipsychotic selection on time to repeat use and LOS in the psychiatric ED. A chart review identified 388 cases in which patients were administered an antipsychotic for agitation in the psychiatric ED between July 1 and August 31, 2014. Time to repeat use and LOS were compared for intramuscular (IM) haloperidol, other IM antipsychotics, and oral second-generation antipsychotics (SGAs) using the Kruskal-Wallis or Wilcoxon-Mann-Whitney test. Of the 388 cases, 31% (n=122) required repeat medications. Mean time to repeat use for IM haloperidol was 20.1±18.4 hours, which was not significantly different from mean time to repeat use in the groups receiving other IM antipsychotics or oral SGAs (P=0.35). The mean LOS was 29.7±28.7 hours for IM haloperidol, 30.3±36.9 hours for other IM antipsychotics, and 22.6±28.0 hours for oral SGAs. Significant differences in LOS between repeat and nonrepeat users of IM haloperidol and other IM antipsychotics were observed, but not among those who received oral SGAs. Mean time to repeat use ranged from 14 to 20 hours with IM haloperidol, other IM antipsychotics, and oral SGAs without significant differences in time to repeat use in the 3 different groups. Repeat users of IM antipsychotics had a significantly longer LOS in the ED compared with nonrepeat users of IM antipsychotics. However, patients who were initially administered oral SGAs did not have longer LOS in the ED even if a repeat dose was given.

Antipsychotic drug therapy is a fundamental tool in the treatment of schizophrenia and other psychoses. Recent years have seen the development of new antipsychotic compounds with an improved acute adverse effect profile; however these are often associated with weight gain and increased risk of metabolic disturbances. Olanzapine, despite its considerable adverse impact on weight gain and associated pathologies, has been recognized as the most efficacious antipsychotic drug in the treatment of ...

Antipsychotic drugs have been associated with sudden cardiac death, but differences in the risk of out-of-hospital cardiac arrest (OHCA) associated with different antipsychotic drug classes are not clear. We identified all OHCAs in Denmark (2001-2010). The risk of OHCA associated with antipsychotic drug use was evaluated by conditional logistic regression analysis in case-time-control models. In total, 2,205 (7.6%) of 28,947 OHCA patients received treatment with an antipsychotic drug at the time of the event. Overall, treatment with any antipsychotic drug was associated with OHCA (odds ratio (OR) = 1.53, 95% confidence interval (CI): 1.23-1.89), as was use with typical antipsychotics (OR = 1.66, CI: 1.27-2.17). By contrast, overall, atypical antipsychotic drug use was not (OR = 1.29, CI: 0.90-1.85). Two individual typical antipsychotic drugs, haloperidol (OR = 2.43, CI: 1.20-4.93) and levomepromazine (OR = 2.05, CI: 1.18-3.56), were associated with OHCA, as was one atypical antipsychotic drug, quetiapine (OR = 3.64, CI: 1.59-8.30).

A higher own-group ethnic density in the area of residence is often associated with a lower risk for psychotic disorder. For common mental disorders the evidence is less convincing. This study explores whether these findings are mirrored in data on dispensing of antipsychotics and antidepressants. Health insurance data on dispensed medication among all adults living in the four largest Dutch cities were linked to demographic data from Statistics Netherlands. Dispensing of antipsychotics and antidepressants in 2013 was analyzed in relation to the proportion of the own ethnic group in the neighborhood. Higher own-group ethnic density was associated with lower dispensing of antipsychotics among the Moroccan-Dutch (N = 115,455), after adjusting for age, gender, and SES of the neighborhood (OR adj for the highest vs. the lowest density quintile = 0.72 [0.66-0.79]). However, this association vanished after adjustment for household composition (OR adj = 0.93 [0.85-1.03]). Similar results were found for the Turkish-Dutch (N = 105,460) (OR adj = 0.86 [0.76-0.96] and 1.05 [0.94-1.18]). For those of Surinamese (N = 147,123) and Antillean origin (N = 41,430), in contrast, the association between ethnic density and lower risk remained after each adjustment (P density was consistently found for those of Antillean origin (OR adj = 0.62 [0.52-0.74]) only. These data on dispensing of psychomedication confirm the ethnic density hypothesis for psychosis alongside earlier equivocal findings for other mental disorders. The negative association between own-group ethnic density and dispensing of antipsychotics among the Moroccan- and Turkish-Dutch may be explained, at least in part, by a favourable household composition (i.e., living in a family) in high-density neighborhoods.

In the past decade, the federal government has frequently investigated and prosecuted pharmaceutical manufacturers for illegal promotion of drugs for indications not approved by the Food and Drug Administration (FDA) ("off-label" uses). State governments can choose to coordinate with the federal investigation, or pursue their own independent state investigations. One of the largest-ever off-label prosecutions relates to the atypical antipsychotic drug olanzapine (Zyprexa). In a series of settlements between 2008 and 2010, Eli Lilly paid $1.4 billion to the federal government and over $290 million to state governments. We examined the effect of these settlements on off-label prescribing of this medication, taking advantage of geographical differences in states' involvement in the investigations and the timing of the settlements. However, we did not find a reduction in off-label prescribing; rather, there were no prescribing changes among states that joined the federal investigation, those that pursued independent state investigations, and states that pursued no investigations at all. Since the settlements of state investigations of off-label prescribing do not appear to significantly impact prescribing rates, policymakers should consider alternate ways of reducing the prevalence of non-evidence-based off-label use to complement their ongoing investigations.

Inappropriate prescribing in older people is a common condition associated with significant morbidity, mortality, and financial costs. Medication use increases with age, and this, in conjunction with an increasing disease burden, is associated with adverse drug reactions. This review outlines why older people are more likely to develop adverse drug reactions and how common the problem is. The use of different tools to identify and measure the problem is reviewed. Common syndromes seen in older adults (eg, falling, cognitive impairment, sleep disturbance) are considered, and recent evidence in relation to medication use for these conditions is reviewed. Finally, we present a brief summary of significant developments in the recent literature for those caring for older people.

Antipsychotic drugs are broadly classified into typical and atypical compounds; they vary in their pharmacological profile however a common component is their antagonist effects at the D2 dopamine receptors (DRD2). Unfortunately, diminished DRD2 activation is generally thought to be associated with the severity of neuroleptic-induced anhedonia. The purpose of this study was to determine the effect of the atypical antipsychotic olanzapine and typical antipsychotic haloperidol in a paradigm that reflects the learned transfer of incentive motivational properties to previously neutral stimuli, namely autoshaping. In order to provide a dosing comparison to a therapeutically relevant endpoint, both drugs were tested against amphetamine-induced disruption of prepulse inhibition as well. In the autoshaping task, rats were exposed to repeated pairings of stimuli that were differentially predictive of reward delivery. Conditioned approach to the reward predictive cue (sign-tracking) and to the reward (goal-tracking) increased during repeated pairings in the vehicle treated rats. Haloperidol and olanzapine completely abolished this behavior at relatively low doses (100 μg/kg). This same dose was the threshold dose for each drug to antagonize the sensorimotor gating deficits produced by amphetamine. At lower doses (3–30 μg/kg) both drugs produced a dose-dependent decrease in conditioned approach to the reward predictive cue. There was no difference between drugs at this dose range which indicates that olanzapine disrupts autoshaping at a significantly lower proposed DRD2 receptor occupancy. Interestingly, neither drug disrupted conditioned approach to the reward at the same dose range that disrupted conditioned approach to the reward predictive cue. Thus, haloperidol and olanzapine, at doses well below what is considered therapeutically relevant, disrupts the attribution of incentive motivational value to previously neutral cues. Drug effects on this dimension of reward

Antipsychotic (AP) drugs are becoming accumulated in terrestrial and aqueous resources due to their actual consumption. Thus, the search of methods for assessing the contamination load of these drugs is mandatory. The COD is a key parameter used for monitoring water quality upon the assessment of the effect of polluting agents on the oxygen level. Thus, the present work aims to assess the chemical oxygen demand (COD) levels of several typical and atypical antipsychotic drugs in order to obtain structure-activity relationships. It was implemented the titrimetric method with potassium dichromate as oxidant and a digestion step of 2h, followed by the measurement of remained unreduced dichromate by titration. After that, an automated sequential injection analysis (SIA) method was, also, used aiming to overcome some drawbacks of the titrimetric method. The results obtained showed a relationship between the chemical structures of antipsychotic drugs and their COD values, where the presence of aromatic rings and oxidable groups give higher COD values. It was obtained a good compliance between the results of the reference batch procedure and the SIA system, and the APs were clustered in two groups, with the values ratio between the methodologies, of 2 or 4, in the case of lower or higher COD values, respectively. The SIA methodology is capable of operating as a screening method, in any stage of a synthetic process, being also more environmentally friendly, and cost-effective. Besides, the studies presented open promising perspectives for the improvement of the effectiveness of pharmaceutical removal from the waste effluents, by assessing COD values.

To identify predictors influencing outcomes, we retrospectively examined the characteristics of inpatients with delirium who required psychiatric medication during hospitalization.Methods: We extracted all new inpatients (n=523 consulted for psychiatric symptoms at Fukushima Medical University Hospital between October 2011 and September 2013. We selected 203 inpatients with delirium diagnosed by psychiatrists. We analyzed data from 177 inpatients with delirium who received psychiatric medication. We defined an “early improvement group” in which delirium resolved in ≤3 days after starting psychiatric medication, and a “prolonged group” with delirium lasting for >3 days. Among the 83 inpatients with renal dysfunction (estimated glomerular filtration rate <60 mL/min/1.73 m2, we defined an “early improvement group with renal dysfunction” in which delirium resolved in ≤3 days after starting psychiatric medication and a “prolonged group with renal dysfunction” with delirium lasting for >3 days. We then examined differences between groups for different categorical variables.Results: Dose of antipsychotic medication at end point was significantly lower in the prolonged group with renal dysfunction than in the early improvement group with renal dysfunction.Conclusion: The results suggest that maintaining a sufficient dose of antipsychotics from an early stage may prevent prolongation of delirium even in inpatients with renal dysfunction.

This paper is a report of a study conducted to explore doctor and non-prescribing nurse views about nurse prescribing in the light of their experience in dermatology. The cooperation of healthcare professionals and peers is of key importance in enabling and supporting nurse prescribing. Lack of understanding of and opposition to nurse prescribing are known barriers to its implementation. Given the important role they play, it is necessary to consider how the recent expansion of nurse prescribing rights in England impacts on the views of healthcare professionals. Interviews with 12 doctors and six non-prescribing nurses were conducted in 10 case study sites across England between 2006 and 2007. Participants all worked with nurses who prescribed for patients with dermatological conditions in secondary or primary care. Thematic analysis was conducted on the interview data. Participants were positive about their experiences of nurse prescribing having witnessed benefits from it, but had reservations about nurse prescribing in general. Acceptance was conditional upon the nurses' level of experience, awareness of their own limitations and the context in which they prescribed. Fears that nurses would prescribe beyond their level of competence were expected to reduce as understanding and experience of nurse prescribing increased. Indications are that nurse prescribing can be acceptable to doctors and nurses so long as it operates within recommended parameters. Greater promotion and assessment of standards and criteria are recommended to improve understanding and acceptance of nurse prescribing.

Neuropsychiatric disorders represent a substantial social and health care issue. The National Institutes of Health estimates that greater than 2 million adults suffer from neuropsychiatric disorders in the USA. These individuals experience symptoms that can include auditory hallucinations, delusions, unrealistic beliefs and cognitive dysfunction. Although antipsychotic medications are available, suboptimal therapeutic responses are observed for approximately one-third of patients. Therefore, there is still a need to explore new pharmacotherapeutic strategies for the treatment of neuropsychiatric disorders. Many of the medications that are used clinically to treat neuropsychiatric disorders have a pharmacological profile that includes being an antagonist at D2-like (D2, D3 and D4) dopamine receptor subtypes. However, dopamine receptor subtypes are involved in a variety of neuronal circuits that include movement coordination, cognition, emotion, affect, memory and the regulation of prolactin. Consequently, antagonism at D2-like receptors can also contribute to some of the adverse side effects associated with the long-term use of antipsychotics including the a) adverse extrapyramidal symptoms associated with the use of typical antipsychotics and b) metabolic side effects (weight gain, hyperglycemia, increased risk of diabetes mellitus, dyslipidemia and gynecomastia) associated with atypical antipsychotic use. Preclinical studies suggest that D3 versus D2 dopamine receptor selective compounds might represent an alternative strategy for the treatment of the symptoms of schizophrenia. In this review we discuss a) how bitropic Nphenylpiperazine D3 dopamine receptor selective compounds have been developed by modification of the primary (orthosteric) and secondary (allosteric or modulatory) pharmacophores to optimize D3 receptor affinity and D2/D3 binding selectivity ratios and b) the functional selectivity of these compounds. Examples of how these compounds might be

French clinical recommendations suggest prescribing long-acting injectable (LAI) antipsychotics to patients with a maintenance treatment indication in schizophrenia. Despite this, and due to their relatively high acquisition and administration costs, LAIs are still underused in clinical practice in France, thus highlighting the need for pharmacoeconomic evaluations. Our objective was to estimate the cost effectiveness of paliperidone LAI (or paliperidone palmitate), a once-monthly second-generation LAI antipsychotic, compared with the most common antipsychotic medications for the maintenance treatment of schizophrenia in France. A Markov model was developed to simulate the progression of a cohort of schizophrenic patients through four health states (stable treated, stable non-treated, relapse and death) and to consider up to three lines of treatment to account for changes in treatment management. Paliperidone LAI was compared with risperidone LAI, aripiprazole LAI, olanzapine LAI, haloperidol LAI (or haloperidol decanoate) and oral olanzapine. Costs, quality-adjusted life-years (QALYs) and number of relapses were assessed over 5 years based on 3-month cycles with a discount rate of 4% and from a French health insurance perspective. Patients were considered to be stabilised after a schizophrenic episode and would enter the model at an initiation phase, followed by a prevention of relapse phase if successful. Data (e.g. relapse or discontinuation rates) for the initiation phase came from randomised clinical trials, whereas relapse rates in the prevention phase were derived from hospitalisation risks based on real-life French data to capture adherence effects. Safety and utility data were derived from international publications. Additionally, costs were retrieved from French health insurance databases and publications. Finally, expert opinion was used for validation purposes or in case of gaps in data. The robustness of results was assessed through deterministic and

Transcranial direct current stimulation (tDCS) has generated interest as a treatment modality for schizophrenia. Dopamine, a critical pathogenetic link in schizophrenia, is also known to influence tDCS effects. We evaluated the influence of antipsychotic drug type (as defined by dopamine D2 receptor affinity) on the impact of tDCS in schizophrenia. DSM-IV-TR-diagnosed schizophrenia patients [N=36] with persistent auditory hallucinations despite adequate antipsychotic treatment were administered add-on tDCS. Patients were divided into three groups based on the antipsychotic's affinity to D2 receptors. An auditory hallucinations score (AHS) was measured using the auditory hallucinations subscale of the Psychotic Symptom Rating Scales (PSYRATS). Add-on tDCS resulted in a significant reduction inAHS. Antipsychotic drug type had a significant effect on AHS reduction. Patients treated with high affinity antipsychotics showed significantly lesser improvement compared to patients on low affinity antipsychotics or a mixture of the two. Furthermore, a significant sex-by-group interaction occurred; type of medication had an impact on tDCS effects only in women. Improvement differences could be due to the larger availability of the dopamine receptor system in patients taking antipsychotics with low D2 affinity. Sex-specific differences suggest potential estrogen-mediated effects. This study reports a first-time observation on the clinical utility of antipsychotic drug type in predicting tDCS effects in schizophrenia. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Full Text Available omorbid psychiatric disorders, frequent hospitalization, multiple outpatient treatment, prior history of hypertension, obesity and lipid dysregulation are associated with higher risk of metabolic syndrome in children. Side effects of antipsychotic drugs and their management have recently become a major subject of research due to enhanced antipsychotic drug usage in child and adolescents. Prevention strategies are usually preferred to secondary or tertiary strategies in the management of metabolic syndrome associated with antipsychotic drugs. Clinicians should present multidisciplinary approach to endocrine and metabolic side effects due to antipsychotic use in pediatric patient groups and avoid multiple drug use in such patients. In this paper, we briefly reviewed metabolic side effects of second generation antipsychotic drugs in child and adolescent population, possible mechanisms of susceptibility to metabolic syndrome and pharmacological and non pharmacological treatment approach to prevention of weight gain.

Abstract This study assessed real-world treatment patterns and antipsychotic (AP) medication adherence among commercially insured US patients with schizoaffective disorder (SCA). Continuously insured adults aged 18 years or older with a diagnosis of SCA from January 1, 2009, to December 31, 2012, were identified from the Clinformatics Data Mart database. Patients were categorized into 2 cohorts: incident or prevalent SCA. Demographics and clinical characteristics were evaluated during the baseline period. Use of psychiatric medications and adherence to AP medications were evaluated during a 12-month follow-up period after index diagnosis of SCA. Of the overall study population (N = 2713; mean age, 40.2 y; 52.7% female), 1961 patients (72.3%) (mean age, 38.7 y; 51.3% female) had incident SCA, and 752 patients (27.7%) (mean age, 43.9 y; 56.5% female) had prevalent SCA. Antipsychotics were used by 74.8% of patients in the overall study population during the follow-up period. The most commonly prescribed oral AP was risperidone (23.9%), followed by quetiapine (21.4%) and aripiprazole (20.4%). Use of any long-acting injectable APs in the overall study population during the follow-up period was less than 3%. A total of 49.0% and 38.0% of the overall study population had medication possession ratios and proportion of days covered for APs of 80% or greater, respectively. Overall use of long-acting injectable APs for the treatment of SCA is low, and adherence to AP medications, measured by both medication possession ratio and proportion of days covered, is suboptimal among patients with SCA in the real-world setting.

Repeated administration of haloperidol and olanzapine causes a progressively enhanced disruption of conditioned avoidance response (CAR) and a progressively enhanced inhibition of phencyclidine (PCP)-induced hyperlocomotion in rats (termed antipsychotic sensitization). Both actions are thought to reflect intrinsic antipsychotic activity. The present study examined to the extent to which antipsychotic-induced sensitization in one model (e.g. CAR) can be transferred or maintained in another (e.g. PCP hyperlocomotion) as a means of investigating the contextual and behavioral controls of antipsychotic sensitization. Well-trained male Sprague-Dawley rats were first repeatedly tested in the CAR or PCP (3.2 mg/kg, sc) hyperlocomotion model under haloperidol or olanzapine for five consecutive days. Then they were switched to the other model and tested for the expression of sensitization. Finally, all rats were switched back to the original model and retested for the expression of sensitization. Repeated haloperidol or olanzapine treatment progressively disrupted avoidance responding and decreased PCP-induced hyperlocomotion, indicating a robust sensitization. When tested in a different model, rats previously treated with haloperidol or olanzapine did not show a stronger inhibition of CAR or PCP-induced hyperlocomotion than those treated with these drugs for the first time; however, they did show such an effect when tested in the original model in which they received repeated antipsychotic treatment. These findings suggest that the expression of antipsychotic sensitization is strongly influenced by the testing environment and/or selected behavioral response under certain experimental conditions. Distinct contextual cues and behavioral responses may enter an association with unconditional drug effects via a Pavlovian conditioning process. They may also serve as occasion-setters to modulate the expression of sensitized responses. Because antipsychotic sensitization mimics
Full Text Available Abstract Background There is an ongoing debate over whether atypical antipsychotics are more effective than typical antipsychotics in the treatment of schizophrenia. This naturalistic study compares atypical and typical antipsychotics on time to all-cause medication discontinuation, a recognized index of medication effectiveness in the treatment of schizophrenia. Methods We used data from a large, 3-year, observational, non-randomized, multisite study of schizophrenia, conducted in the U.S. between 7/1997 and 9/2003. Patients who were initiated on oral atypical antipsychotics (clozapine, olanzapine, risperidone, quetiapine, or ziprasidone or oral typical antipsychotics (low, medium, or high potency were compared on time to all-cause medication discontinuation for 1 year following initiation. Treatment group comparisons were based on treatment episodes using 3 statistical approaches (Kaplan-Meier survival analysis, Cox Proportional Hazards regression model, and propensity score-adjusted bootstrap resampling methods. To further assess the robustness of the findings, sensitivity analyses were performed, including the use of (a only 1 medication episode for each patient, the one with which the patient was treated first, and (b all medication episodes, including those simultaneously initiated on more than 1 antipsychotic. Results Mean time to all-cause medication discontinuation was longer on atypical (N = 1132, 256.3 days compared to typical antipsychotics (N = 534, 197.2 days; p Conclusion In the usual care of schizophrenia patients, time to medication discontinuation for any cause appears significantly longer for atypical than typical antipsychotics regardless of the typical antipsychotic potency level. Findings were primarily driven by clozapine and olanzapine, and to a lesser extent by risperidone. Furthermore, only clozapine and olanzapine therapy showed consistently and significantly longer treatment duration compared to perphenazine, a medium

Repeated administration of haloperidol (HAL) and olanzapine (OLZ) causes a progressively enhanced disruption of the conditioned avoidance response (CAR) and a progressively enhanced inhibition of phencyclidine (PCP)-induced hyperlocomotion in rats (termed antipsychotic sensitization). Both actions are thought to reflect intrinsic antipsychotic activity. The present study examined the extent to which antipsychotic-induced sensitization in one model (e.g. CAR) can be transferred or maintained in another (e.g. PCP hyperlocomotion) as a means of investigating the contextual and behavioral controls of antipsychotic sensitization. Well-trained male Sprague-Dawley rats were first repeatedly tested in the CAR or the PCP (3.2 mg/kg, subcutaneously) hyperlocomotion model under HAL or OLZ for 5 consecutive days. Then they were switched to the other model and tested for the expression of sensitization. Finally, all rats were switched back to the original model and retested for the expression of sensitization. Repeated HAL or OLZ treatment progressively disrupted avoidance responding and decreased PCP-induced hyperlocomotion, indicating a robust sensitization. When tested in a different model, rats previously treated with HAL or OLZ did not show a stronger inhibition of CAR-induced or PCP-induced hyperlocomotion than those treated with these drugs for the first time; however, they did show such an effect when tested in the original model in which they received repeated antipsychotic treatment. These findings suggest that the expression of antipsychotic sensitization is strongly influenced by the testing environment and/or selected behavioral response under certain experimental conditions. Distinct contextual cues and behavioral responses may develop an association with unconditional drug effects through a Pavlovian conditioning process. They may also serve as occasion setters to modulate the expression of sensitized responses. As antipsychotic sensitization mimics the clinical
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.

The treatment of fibromyalgia requires pharmacological and nonpharmacological therapies. The pharmacological treatment of fibromyalgia is limited to a few drugs that have been demonstrated to be moderately effective in some but not all dimensions of the disease. Therefore, the search for new drugs to treat this condition is warranted. Atypical antipsychotics offered an attractive alternative because they had been shown to be active against several key symptoms of fibromyalgia. The results of open-label studies, however, appear to indicate that atypical antipsychotics are poorly tolerated in patients with fibromyalgia, and only quetiapine XR has been studied in randomized controlled trials. Quetiapine XR has demonstrated effectiveness in treating comorbid major depression, anxiety and sleep disturbance. However, in two randomized controlled trials, quetiapine XR was not differentiated from placebo and failed to demonstrate noninferiority to amitriptyline in terms of improving overall symptomatology. The effect of quetiapine XR on pain and its usefulness as part of a combination pharmacological regimen should be further evaluated. Overall, the use of quetiapine (initiated at a low dose and slowly titrated) in fibromyalgia should be limited to patients with comorbid major depression or patients who are currently receiving other treatments and have unresolved and disabling depressive and/or anxiety symptoms.

Schizophrenia and other psychotic disorders are associated with high morbidity and mortality, due to inherent health factors, genetic factors, and factors related to psychopharmacological treatment. Antipsychotics, like other drugs, have side-effects that can substantially affect the physical health of patients, with substantive differences in the side-effect profile and in the patients in which these side-effects occur. To understand and identify these risk groups could help to prevent the occurrence of the undesired effects. A prospective study, with 24 months follow-up, was conducted in order to analyse the physical health of severe mental patients under maintenance treatment with atypical antipsychotics, as well as to determine any predictive parameters at anthropometric and/or analytical level for good/bad outcome of metabolic syndrome in these patients. There were no significant changes in the physical and biochemical parameters individually analysed throughout the different visits. The baseline abdominal circumference (lambda Wilks P=.013) and baseline HDL-cholesterol levels (lambda Wilks P=.000) were the parameters that seem to be more relevant above the rest of the metabolic syndrome constituents diagnosis criteria as predictors in the long-term. In the search for predictive factors of metabolic syndrome, HDL-cholesterol and abdominal circumference at the time of inclusion were selected, as such that the worst the baseline results were, the higher probability of long-term improvement.

to study the efficacy of the GABA-ergic drug pantogam active (D-, L-gopantenic acid) in patients with schizophrenia treated with typical neuroleptics and to assess the rate of treatment response and tolerability of the drug. A sample consisted of 70 patients with schizophrenia stratified into main (n=35) and control (n=35) groups. All patients received one of typical antipsychotics (haloperidol, zuclopenthixol, promazine or perphenazine). Patients of the main group received in addition pantogam active in dose of 1200-1800 mg daily. The maximum allowed dose of 1800 mg daily was used in 62.9% of the patients. The long-term combined therapy with the addition of D-, L-gopantenic acid (pantogam activ) allowed to achieve clinical improvement earlier (on 8th week in the main group versus 16th week in the control group). The frequency and severity of secondary negative symptoms associated with antipsychotic therapy were decreased as well. The high efficacy and tolerability of the combined therapy allow to improve quality of life in patients with schizophrenia and their compliance to treatment as well as to reduce costs of medical care.

This review summarizes the randomized, double-blind, controlled studies of AAPs in EOS, including clozapine, risperidone, olanzapine, aripiprazole, paliperidone, quetiapine, and ziprasidone. No significant differences in efficacy between AAPs were found, with the exception of clozapine and ziprasidone. Clozapine demonstrated superior efficacy in treatment-resistant patients with EOS, whereas ziprasidone failed to demonstrate efficacy in the treatment of EOS. Our review also focuses on the onset of action and weight gain associated with AAPs. The data on onset of action of AAPs in pediatric psychiatry are scanty and inconsistent. Olanzapine appears to cause the most significant weight gain in patients with EOS, while ziprasidone and aripiprazole seem to cause the least.

A recent cluster-randomized controlled trial found that offering financial incentives improves adherence to long-acting injectable antipsychotics (LAIs). The present study investigates whether the impact of incentives diminishes over time and whether the improvement in adherence is linked to the amount of incentives offered. Seventy-three teams with 141 patients with psychotic disorders (using ICD-10) were randomized to the intervention or control group. Over 1 year, patients in the intervention group received £15 (US $23) for each LAI, while control patients received treatment as usual. Adherence levels, ie, the percentage of prescribed LAIs that were received, were calculated for quarterly intervals. The amount of incentives offered was calculated from the treatment cycle at baseline. Multilevel models were used to examine the time course of the effect of incentives and the effect of the amount of incentives offered on adherence. Adherence increased in both the intervention and the control group over time by an average of 4.2% per quarterly interval (95% CI, 2.8%-5.6%; P time and treatment group. Further, a higher total amount of incentives was associated with poorer adherence (βbootstrapped = -0.11; 95% CIbootstrapped, -0.20 to -0.01; P = .023). A substantial effect of financial incentives on adherence to LAIs occurs within the first 3 months of the intervention and is sustained over 1 year. A higher total amount of incentives does not increase the effect. ISRCTN.com identifier: ISRCTN77769281 and UKCRN.org identifier: 7033. © Copyright 2015 Physicians Postgraduate Press, Inc.

Antipsychotic (neuroleptic) medication is used extensively to treat people with chronic mental illnesses. Its use, however, is associated with adverse effects, including movement disorders such as tardive dyskinesia (TD) - a problem often seen as repetitive involuntary movements around the mouth and face. Vitamin E has been proposed as a treatment to prevent or decrease TD. The primary objective was to determine the clinical effects of vitamin E in people with schizophrenia or other chronic mental illness who had developed antipsychotic-induced TD.The secondary objectives were:1. to examine whether the effect of vitamin E was maintained as duration of follow-up increased;2. to test the hypothesis that the use of vitamin E is most effective for those with early onset TD (less than five years) SEARCH METHODS: We searched the Cochrane Schizophrenia Group Trials Register (July 2015 and April 2017), inspected references of all identified studies for further trials and contacted authors of trials for additional information. We included reports if they were controlled trials dealing with people with antipsychotic-induced TD and schizophrenia who remained on their antipsychotic medication and had been randomly allocated to either vitamin E or to a placebo, no intervention, or any other intervention. We independently extracted data from these trials and we estimated risk ratios (RR) or mean differences (MD), with 95% confidence intervals (CI). We assumed that people who left early had no improvement. We assessed risk of bias and created a 'Summary of findings' table using GRADE. The review now includes 13 poorly reported randomised trials (total 478 people), all participants were adults with chronic psychiatric disorders, mostly schizophrenia, and antipsychotic-induced TD. There was no clear difference between vitamin E and placebo for the outcome of TD: not improved to a clinically important extent (6 RCTs, N = 264, RR 0.95, 95% CI 0.89 to 1.01, low-quality evidence
Full Text Available Abstract Background Nonadherence with antipsychotic medication is an important clinical and economic problem in the treatment of schizophrenia. This study identified treatment patterns and clinical characteristics that immediately precede the initiation of depot typical antipsychotics in the usual treatment of schizophrenia patients with a recent history of nonadherence with oral antipsychotic regimens. Methods Data were drawn from a large, multisite, 3-year prospective noninterventional observational study of persons treated for schizophrenia in the United States, which was conducted between 7/1997 and 9/2003. The analytical sample included patients who, in the 6 months prior to enrollment, were considered nonadherent with oral antipsychotics and were not treated with depot antipsychotics (N = 314. Patients who were subsequently initiated on typical depots during the 3-year follow-up were compared with patients who continued therapy with only oral antipsychotic agents. Group comparisons were made on patient baseline characteristics and precedent variables that were assessed 1 to 6 months prior to depot initiation. Patient assessments were made at predetermined intervals throughout the 3-year study using standard psychiatric measures, a patient-reported questionnaire, and medical record information. Results A small proportion of patients (12.4% who were recently nonadherent with oral antipsychotics were subsequently initiated on depot therapy during the 3-year study. Compared to patients treated with only oral antipsychotics, those subsequently initiated on a depot were significantly more likely to be hospitalized at depot initiation or the previous 30 days, to have recent involvement with the criminal justice system (arrests, recent illicit drug use, recent switching or augmentation of oral antipsychotics, and recent treatment with oral typical antipsychotics. Conclusion Despite prior nonadherence with oral antipsychotic medication, only a

1. Medication errors are common in general practice and in hospitals. Both errors in the act of writing (prescription errors) and prescribing faults due to erroneous medical decisions can result in harm to patients. 2. Any step in the prescribing process can generate errors. Slips, lapses, or mistakes are sources of errors, as in unintended omissions in the transcription of drugs. Faults in dose selection, omitted transcription, and poor handwriting are common. 3. Inadequate knowledge or competence and incomplete information about clinical characteristics and previous treatment of individual patients can result in prescribing faults, including the use of potentially inappropriate medications. 4. An unsafe working environment, complex or undefined procedures, and inadequate communication among health-care personnel, particularly between doctors and nurses, have been identified as important underlying factors that contribute to prescription errors and prescribing faults. 5. Active interventions aimed at reducing prescription errors and prescribing faults are strongly recommended. These should be focused on the education and training of prescribers and the use of on-line aids. The complexity of the prescribing procedure should be reduced by introducing automated systems or uniform prescribing charts, in order to avoid transcription and omission errors. Feedback control systems and immediate review of prescriptions, which can be performed with the assistance of a hospital pharmacist, are also helpful. Audits should be performed periodically.

Doctor shopping is a primary method of prescription medication diversion. After opioids, benzodiazepines and stimulants are the next most common prescription medications used nonmedically. Studies have shown that patients who engage in doctor shopping find it fun, exciting, and easy to do. There is a lack of research on the prescriber's perspective on the phenomenon of doctor shopping. This study investigates the experiences of prescribers in psychiatry with patients who engage in doctor shopping. Fifteen prescribers including psychiatrists and psychiatric nurse practitioners working in outpatient psychiatry were interviewed to elicit detailed information about their experiences with patients who engage in doctor shopping. Themes found throughout the interview were that psychiatric prescribers' experience with patients who engage in doctor shopping includes (a) detecting red flags, (b) negative emotional responding, (c) addressing the patient and the problem, and (d) inconsistently implementing precautions. When red flags were detected when prescribing controlled drugs, prescribers in psychiatry experienced both their own negative emotional responses such as disappointment and resentment as well as the negative emotions of the patients such as anger and other extreme emotional responses. Psychiatric prescribers responded to patient's doctor shopping in a variety of ways such as changing their practice, discharging the patients or taking steps to not accept certain patients identified as being at risk for doctor shopping, as well as by talking to the patient and trying to offer them help. Despite experiencing doctor shopping, the prescribers inconsistently implemented precautionary measures such as checking prescription drug monitoring programs. © The Author(s) 2015.

The patients were evaluated using 1H magnetic resonance spectroscopy in the dorsolateral prefrontal cortex and Positive and Negative Syndrome Scale, Clinical Global Impression Scale of Severity, Tower of London – Drexel University, Letter–Number Span Test, Trail Making Test A, and Personal and Social Performance Scale. They were administered atypical antipsychotics, starting with quetiapine. In the absence of a therapeutic response, another antipsychotic was introduced.Results: After 12 study months, the N-acetylaspartate/creatine (NAA/Cr level did not significantly change at the whole-group level. Additional analysis revealed a significant rise in the NAA/Cr level in the study group that stayed on the same antipsychotic throughout the study course (P=0.008 and a significant drop in NAA/Cr in the study group that switched antipsychotics (P=0.005. On the whole-group level, no significant correlations between NAA/Cr values and other scores were found at either baseline or after 12 study months.Conclusion: One-year treatment with atypical antipsychotics administered to antipsychotic-naïve patients didn’t result

Risperidone, aripiprazole, and pipamperone are antipsychotic drugs frequently prescribed for the treatment of comorbid behavioral problems in children with autism spectrum disorders. Therapeutic drug monitoring (TDM) could be useful to decrease side effects and to improve patient outcome. Dried blood spot (DBS) sample collection seems to be an attractive technique to develop TDM of these drugs in a pediatric population. The aim of this work was to develop and validate a DBS assay suitable for TDM and home sampling. Risperidone, 9-OH risperidone, aripiprazole, dehydroaripiprazole, and pipamperone were extracted from DBS and analyzed by ultra-high-performance liquid chromatography-tandem mass spectrometry using a C18 reversed-phase column with a mobile phase consisting of ammonium acetate/formic acid in water or methanol. The suitability of DBS for TDM was assessed by studying the influence of specific parameters: extraction solution, EDTA carryover, hematocrit, punching location, spot volume, and hemolysis. The assay was validated with respect to conventional guidelines for bioanalytical methods. The method was linear, specific without any critical matrix effect, and with a mean recovery around 90%. Accuracy and imprecision were within the acceptance criteria in samples with hematocrit values from 30% to 45%. EDTA or hemolysis did not skew the results, and no punching carryover was observed. No significant influence of the spot volume or the punch location was observed. The antipsychotics were all stable in DBS stored 10 days at room temperature and 1 month at 4 or -80°C. The method was successfully applied to quantify the 3 antipsychotics and their metabolites in patient samples. A UHPLC-MS/MS method has been successfully validated for the simultaneous quantification of risperidone, 9-OH risperidone, aripiprazole, dehydroaripiprazole, and pipamperone in DBS. The assay provided good analytical performances for TDM and clinical research applications.

The aim of this study was to identify the factors that influence prescribing of new drugs among general practitioners, endocrinologists and psychiatrists. Four focus groups were conducted with GPs, endocrinologists and psychiatrists on sources of awareness and influences on prescribing of new drugs. Pharmaceutical companies were the most important source for becoming aware of new drugs. There were many influences on the decision to prescribe a new drug, the most important being efficacy, safety, cost and advantage over existing therapies. Endocrinologists placed greater emphasis on evidence from clinical trials and scientific conferences, and psychiatrists and GPs placed more weight on pharmaceutical representatives, colleagues and specialists. New drug prescribing occurs in a complex environment with many influences. Effective interventions to promote rational, safe and effective prescribing of new drugs will need to be cognisant of these factors.

In Slovenia, there has been no evidence about the prescribing patterns for inpatients with psychotic disorders. The research aims to analyze drug utilization patterns for inpatients with psychotic disorder that are coded as F20-F29 according to International Classification of Diseases (ICD) 10 th revision (schizophrenia spectrum disorders). Prospective research was conducted at the Psychiatric Hospital Idrija. The medical records of the inpatients admitted over a 12-month period were collected from the beginning to the end of their hospitalization. A total of 311 inpatients with 446 hospitalizations were included, producing a total of 3954 medication prescriptions. Medications prescribed pro re nata (the use of as needed) were also taken into account. Antipsychotics (N=1149, 43% of prescriptions) were the most often prescribed medications, followed by anxiolytics, antiparkinsonians, antidepressants, mood stabilizers and cardiovascular drugs. A total of 256 (82%) inpatients received at least one pro re nata medication. It was observed that the studied population was treated with one antipsychotic on 27 percent of prescriptions. Inpatients with schizophrenia spectrum disorders were exposed to a large number of different drugs. They were not received only psychotropic drugs but also other medications. With the knowledge about medications the implementation of clinical pharmacy services to the psychiatrists would significantly improve medication of inpatients with psychotic disorders and polypharmacotherapy.

Full Text Available There is urgent need for the development of mechanistically different and less side-effect prone antipsychotic compounds. The endocannabinoid system has been suggested to represent a potential new target in this indication. While the chronic use of cannabis itself has been considered a risk factor contributing to the development of schizophrenia, triggered by the phytocannabinoid delta-9-tetrahydrocannabinol (Δ9 THC, cannabidiol, the second most important phytocannabinoid, appears to have no psychotomimetic potential. Although results from animal studies are inconsistent to a certain extent and seem to depend on behavioral paradigms, treatment duration and experimental conditions applied, cannabidiol has shown antipsychotic properties in rodents and rhesus monkeys. After some individual treatment attempts, the first randomized, double-blind controlled clinical trial had been conducted and demonstrated that cannabidiol exerts antipsychotic properties in acute schizophrenia comparable to the antipsychotic drug amisulpride accompanied by a superior, placebo-like side effect profile. As the clinical improvement by cannabidiol was significantly associated with elevated anandamide levels, it appears likely that its antipsychotic action is based on mechanisms associated with increased anandamide concentrations. However, a plethora of mechanisms of action has been suggested, but their potential relevance for the antipsychotic effects of cannabidiol needs still to be investigated. The clarification of these mechanisms as well as the establishment of cannabidiol’s antipsychotic efficacy and its hopefully benign side-effect profile remains the subject of a number of previously started clinical trials.

In spite of the significant impact that the serendipitous discovery of drugs with antipsychotic properties had on the care of patients with psychotic disorders, there are significant challenges when aiming at therapeutic goals such as remission, recovery, improved health-related quality of life and functioning. The efficacy and effectiveness of existing antipsychotic drugs fail to address the full spectrum of symptoms and functional deficits that currently prevent patients with psychotic disorders from achieving fulfilling lives. The study of the pharmacological mechanism of action has increased our knowledge on molecular targets and brain circuits related to the antipsychotic properties of this drug class. However, our understanding of how these molecular targets and brain circuits relate to other aspects of disease pathophysiology like cognitive impairment and negative symptoms is incomplete although these are significant clinical unmet needs. Currently, there is still an important knowledge gap between psychopathology and pathophysiology in schizophrenia research. This may have contributed to some recent costly failures of large clinical development programs for drugs targeted at glutamatergic function and nicotinic receptors. The lack of success of these pharmacological approaches to achieve clinical validation raises important questions concerning the underlying hypothesis that guided the choice of molecular targets, and about the predictive validity of translational models that supported the rationale for testing these drugs in clinical studies. From a clinical perspective there is a need to more strongly consider the disease heterogeneity linked to the use of the current diagnostic classification of subjects and to the validity of the psychopathological constructs and assessments that are used to assess clinical outcomes. A paradigm shift in the development of drugs for schizophrenia is needed. This will require among other addressing: the shortcomings of a

It is a particular challenge in schizophrenia due to the illness's association with social isolation, stigma, and comorbid substance misuse, plus the effect of symptom domains on adherence, including positive and negative symptoms, lack of insight, depression, and cognitive impairment. Nonadherence lies on a spectrum, is often covert, and is underestimated by clinicians, but affects more than one third of patients with schizophrenia per annum. It increases the risk of relapse, rehospitalization, and self-harm, increases inpatient costs, and lowers quality of life. It results from multiple patient, clinician, illness, medication, and service factors, but a useful distinction is between intentional and unintentional nonadherence. There is no gold standard approach to the measurement of adherence as all methods have pros and cons. Interventions to improve adherence include psychoeducation and other psychosocial interventions, antipsychotic long-acting injections, electronic reminders, service-based interventions, and financial incentives. These overlap, all have some evidence of effectiveness, and the intervention adopted should be tailored to the individual. Psychosocial interventions that utilize combined approaches seem more effective than unidimensional approaches. There is increasing interest in electronic reminders
Full Text Available The association between antipsychotic use and the risk of stroke in schizophrenic patients is controversial. We sought to study the association in a nationwide cohort with schizophrenia.Using a retrospective cohort of patients with schizophrenia (N = 31,976 derived from the Taiwan National Health Insurance Research Database, 802 new-onset cases of stroke were identified within 10 years of follow-up (from 2000 through 2010. We designed a case-crossover study using 14-day windows to explore the risk factors of stroke and the association between antipsychotic drugs and the risk of stroke. We analyzed the risks of individual antipsychotics on various subgroups of stroke including ischemic, hemorrhagic, and other strokes, and the risks based on the antipsychotic receptor-binding profile of each drug.Use of any second-generation antipsychotic was associated with an increased risk of stroke (adjusted risk ratio = 1.45, P = .009 within 14 days while the use of any first-generation antipsychotic was not. Intriguingly, the use of any second-generation antipsychotic was associated with ischemic stroke but not hemorrhagic stroke. The antipsychotic receptor-binding profile analysis showed that the antihistamine 1 receptor was significantly associated with ischemic stroke (adjusted risk ratio = 1.72, P = .037, and the sensitivity analysis based on the 7-day window of exposure validated the association (adjusted risk ratio = 1.87, P = .015.Use of second-generation antipsychotic drugs appeared to be associated with an increased risk of ischemic stroke in the patients studied, possibly mediated by high affinity for histamine-1 receptor blockade. Further research regarding the underlying biological mechanism and drug safety is suggested.

To outline the development and content of a 'top-up' neuropharmacology module for mental health nurse prescribers and consider how much pharmacology training is required to ensure effective mental health prescribing practice. Debate about the content of prescribing training courses has persisted within the United Kingdom since the mid-1980s. In early 2003 supplementary prescribing was introduced and gave mental health nurses the opportunity to become prescribers. The challenge of the nurse prescribing curriculum for universities is that they have only a short time to provide nurses from a range of backgrounds with enough knowledge to ensure that they meet agreed levels of competency for safe prescribing. There is growing concern within mental health care that the prescribing of medication in mental health services falls short of what would be deemed good practice. Over the past two decades, nurse training has increasingly adopted a psychosocial approach to nursing care raising concerns that, although nurses attending prescribing training may be able to communicate effectively with service users, they may lack the basic knowledge of biology and pharmacology to make effective decisions about medication. Following the completion of a general nurse prescribing course, mental health nurses who attended were asked to identify their specific needs during the evaluation phase. Although they had covered basic pharmacological principles in their training, they stated that they needed more specific information about drugs used in mental health; particularly how to select appropriate drug treatments for mental health conditions. This paper describes how the nurses were involved in the design of a specific module which would enable them to transfer their theoretical leaning to practice and in so doing increase their confidence in their new roles. The findings of this study suggest that the understanding and confidence of mental health nurse prescribers about the drugs they

Conventional and atypical antipsychotic medications are approved by the FDA for treatment of schizophrenia and bipolar disorder. Over many decades, the widespread use of conventional antipsychotics produced various side effects requiring additional medications, such as the atypical antipsychotics. Beginning in 2006, 9 atypical antipsychotic drugs have been approved by the FDA for indications that were previously off-label uses: aripiprazole (as augmentation for major depressive disorder [MDD] and for autism spectrum disorders), asenapine, clozapine, iloperidone, olanzapine (in combination with fluoxetine for MDD and bipolar depression), paliperidone, quetiapine (quetiapine and quetiapine XR [extended release] as monotherapy in bipolar depression and quetiapine XR as augmentation for MDD), risperidone (for autism spectrum disorders), and ziprasidone. In 2006, the Agency for Healthcare Research and Quality (AHRQ) published a systematic review on the comparative effectiveness of off-label uses of atypical antipsychotics. Since that time, numerous studies have been published evaluating these therapies in various new off-label uses; new or increased adverse effects have been observed with off-label uses; new atypical antipsychotics have been approved; and previously off-label uses have been approved for some atypical antipsychotics. Hence, AHRQ published an updated review in September 2011 that summarized the benefits and harms of atypical antipsychotics in the treatment of attention-deficit hyperactivity disorder/attention deficit disorder (ADHD), anxiety, behavioral disturbances of dementia and severe geriatric agitation, depression, eating disorders, insomnia, obsessive-compulsive disorder (OCD), personality disorder, post-traumatic stress disorder (PTSD), substance use and dependence disorders, and Tourette's syndrome. The new report also investigated topics for which data in the previous report were found to be insufficient to make conclusions, including

To assess the types and frequency of antibiotic prescriptions by Belgian dentists, the indications for antibiotic prescription, and dentists' knowledge about recommended practice in antibiotic use. In this cross-sectional survey, dental practitioners were asked to record information about all antibiotics prescribed to their patients during a 2-week period. The dental practitioners were also asked to complete a self-administered questionnaire regarding demographic data, prescribing practices, and knowledge about antibiotic use. A random sample of 268 Belgian dentists participated in the survey. During the 2-week period, 24 421 patient encounters were recorded; 1033 patients were prescribed an antibiotic (4.2%). The median number of prescriptions per dentist for the 2 weeks was 3. Broad spectrum antibiotics were most commonly prescribed: 82% of all prescriptions were for amoxycillin, amoxycillin-clavulanic acid and clindamycin. Antibiotics were often prescribed in the absence of fever (92.2%) and without any local treatment (54.2%). The most frequent diagnosis for which antibiotics were prescribed was periapical abscess (51.9%). Antibiotics were prescribed to 63.3% of patients with periapical abscess and 4.3% of patients with pulpitis. Patterns of prescriptions were confirmed by the data from the self-reported practice. Discrepancies between observed and recommended practice support the need for educational initiatives to promote rational use of antibiotics in dentistry in Belgium.

To evaluate the effectiveness of feedback on safety of prescribing compared with moderately enhanced usual care. Three arm, highly pragmatic cluster randomised trial. 262/278 (94%) primary care practices in three Scottish health boards. Practices were randomised to: "usual care," consisting of emailed educational material with support for searching to identify patients (88 practices at baseline, 86 analysed); usual care plus feedback on practice's high risk prescribing sent quarterly on five occasions (87 practices, 86 analysed); or usual care plus the same feedback incorporating a behavioural change component (87 practices, 86 analysed). The primary outcome was a patient level composite of six prescribing measures relating to high risk use of antipsychotics, non-steroidal anti-inflammatories, and antiplatelets. Secondary outcomes were the six individual measures. The primary analysis compared high risk prescribing in the two feedback arms against usual care at 15 months. Secondary analyses examined immediate change and change in trend of high risk prescribing associated with implementation of the intervention within each arm. In the primary analysis, high risk prescribing as measured by the primary outcome fell from 6.0% (3332/55 896) to 5.1% (2845/55 872) in the usual care arm, compared with 5.9% (3341/56 194) to 4.6% (2587/56 478) in the feedback only arm (odds ratio 0.88 (95% confidence interval 0.80 to 0.96) compared with usual care; P=0.007) and 6.2% (3634/58 569) to 4.6% (2686/58 582) in the feedback plus behavioural change component arm (0.86 (0.78 to 0.95); P=0.002). In the pre-specified secondary analysis of change in trend within each arm, the usual care educational intervention had no effect on the existing declining trend in high risk prescribing. Both types of feedback were associated with significantly more rapid decline in high risk prescribing after the intervention compared with before. Feedback of prescribing safety data
Clinical expectations are high toward atypical, second generation antipsychotics (SGAs). Controlled clinical trials supporting the superiority of SGAs over traditional agents are scarce. Meta-analysis of existing data may come for the rescue but that kind of method has its limitations. One of the most meticulous approaches (Davis et al. 2003) reached the conclusion that some, but not all, SGAs are more efficacious than traditional ones. Within the group of distinguished drugs, clozapine and amisulpride have the highest efficacy. The present paper critically overviews the study of the Davis group. Based on in vivo D2 receptor binding data of the new SGAs and the usual post marketing changes of clinical dosing, it is expected that some of the currently and most recently marketed SGAs may show similar superiority.

People with severe mental illness have a 20-year life-expectancy shortfall. The majority of antipsychotic medications are associated with obesity and heightened diabetes risk. People with severe mental illness less frequently achieve benchmarked diabetes care, often attributed to poor adherence, lower clinical attendance and documented medical biases in treatment. This case is presented to highlight the profound effect medication change can have on diabetes control. A 56-year-old man with a 42-year history of schizophrenia had required clozapine treatment for the preceding 14 years. Type 2 diabetes and obesity occurred within 4 years of clozapine instigation. Glycaemic control had been continuously poor, despite frequent contact with diabetes services and multiple medications, including insulin at a dose exceeding 200 IU daily. Request for consideration of antipsychotic review and close interaction with the psychiatry team was initiated at the diabetes outpatient clinic. A gradual medication switch from clozapine to aripiprazole was associated with a reduction in HbA(1c) from 80 to 50 mmol/mol (9.5 to 6.7%) over 4 months, associated with a weight loss of 10 kg. Over the ensuing 2 years, the improvement in HbA(1c) has endured, with total weight loss of 13 kg and halving of insulin requirements. This case illustrates the benefits of engagement between endocrinologists and psychiatrists to achieve the shared goal of improved physical health in severe mental illness. Greater interdisciplinary collaboration will help bridge the life-expectancy gap in severe mental illness and may assist in preventing disabling diabetes complications in this vulnerable patient group. © 2013 The Authors.

Nonadherence with medication occurs in all chronic medical disorders. It is a particular challenge in schizophrenia due to the illness's association with social isolation, stigma, and comorbid substance misuse, plus the effect of symptom domains on adherence, including positive and negative symptoms, lack of insight, depression, and cognitive impairment. Nonadherence lies on a spectrum, is often covert, and is underestimated by clinicians, but affects more than one third of patients with schizophrenia per annum. It increases the risk of relapse, rehospitalization, and self-harm, increases inpatient costs, and lowers quality of life. It results from multiple patient, clinician, illness, medication, and service factors, but a useful distinction is between intentional and unintentional nonadherence. There is no gold standard approach to the measurement of adherence as all methods have pros and cons. Interventions to improve adherence include psychoeducation and other psychosocial interventions, antipsychotic long-acting injections, electronic reminders, service-based interventions, and financial incentives. These overlap, all have some evidence of effectiveness, and the intervention adopted should be tailored to the individual. Psychosocial interventions that utilize combined approaches seem more effective than unidimensional approaches. There is increasing interest in electronic reminders and monitoring systems to enhance adherence, eg, Short Message Service text messaging and real-time medication monitoring linked to smart pill containers or an electronic ingestible event marker. Financial incentives to enhance antipsychotic adherence raise ethical issues, and their place in practice remains unclear. Simple pragmatic strategies to improve medication adherence include shared decision-making, regular assessment of adherence, simplification of the medication regimen, ensuring that treatment is effective and that side effects are managed, and promoting a positive

This is an update of the original Cochrane Review, last published in 2012 (Loy 2012). Children and youths with disruptive behaviour disorders may present to health services, where they may be treated with atypical antipsychotics. There is increasing usage of atypical antipsychotics in the treatment of disruptive behaviour disorders. To evaluate the effect and safety of atypical antipsychotics, compared to placebo, for treating disruptive behaviour disorders in children and youths. The aim was to evaluate each drug separately rather than the class effect, on the grounds that each atypical antipsychotic has different pharmacologic binding profile (Stahl 2013) and that this is clinically more useful. In January 2017, we searched CENTRAL, MEDLINE, Embase, five other databases and two trials registers. Randomised controlled trials of atypical antipsychotics versus placebo in children and youths aged up to and including 18 years, with a diagnosis of disruptive behaviour disorders, including comorbid ADHD. The primary outcomes were aggression, conduct problems and adverse events (i.e. weight gain/changes and metabolic parameters). The secondary outcomes were general functioning, noncompliance, other adverse events, social functioning, family functioning, parent satisfaction and school functioning. We used standard methodological procedures expected by Cochrane. Two review authors (JL and KS) independently collected, evaluated and extracted data. We used the GRADE approach to assess the quality of the evidence. We performed meta-analyses for each of our primary outcomes, except for metabolic parameters, due to inadequate outcome data. We included 10 trials (spanning 2000 to 2014), involving a total of 896 children and youths aged five to 18 years. Bar two trials, all came from an outpatient setting. Eight trials assessed risperidone, one assessed quetiapine and one assessed ziprasidone. Nine trials assessed acute efficacy (over four to 10 weeks); one of which combined

One solution to the challenges of care delivery has been the introduction of nurse practitioners (NPs and the authorization of NPs to prescribe medicines. Aim: The aim of this paper was to review the current international literature related to NP prescribing and compare the findings to the Australian context. The review focuses on literature from the United States, Canada, Europe, Australia, and New Zealand. Methods: Databases were searched from January 2000 to January 2015. The following keywords: “nurse practitioner”, “advanced nurse”, “advanced practice nurse”, “prescri*”, “Australia”, “United States America”, “UK”, “New Zealand”, “Canada”, “Europe”, “drug prescri*”, “prescri* authority”, and “prescri* legislation” were used. Findings: NPs tend to prescribe in differing contexts of practice to provide care in underserved populations and require good systems literacy to practice across complex systems. The key themes identified internationally related to NP prescribing relate to barriers to prescribing, confidence in prescribing, and the unique role of NPs in prescribing medicines, eg, the high prevalence of prescribing pain medicines in several countries, including Australia. Conclusion: Across all countries reviewed, there appears a need for further research into the organizational and

Clozapine is an atypical antipsychotic medicine which can cause significant side-effects. It is often prescribed off-license in severe cases of borderline personality disorder contrary to national treatment guidelines. Little is known about the experiences of those who take clozapine for borderline personality disorder. We explored the lived-experience of women in secure inpatient care who were prescribed clozapine for borderline personality disorder. Adult females ( N = 20) participated in audio-taped semi-structured interviews. Transcripts were subject to thematic analysis. The central themes related to evaluation, wellbeing, understanding and self-management; for many, their subjective wellbeing on clozapine was preferred to prior levels of functioning and symptomatology, sometimes profoundly so. The negative and potentially adverse effects of clozapine were explained as regrettable but relatively unimportant. When psychological interventions are, at least initially, ineffective then clozapine treatment is likely to be evaluated positively by a group of women with borderline personality disorder in secure care despite the potential disadvantages.
-generation antipsychotics (SGAs ushered in a progressive shift from the paternalistic management of SMI symptoms to a patient-centered approach, which emphasized targets important to patients – psychosocial functioning, quality of life, and recovery. These drugs are no longer limited to specific Diagnostic and Statistical Manual of Mental Disorders (DSM categories. Evidence indicates that SGAs show an improved safety and tolerability profile compared with FGAs. The incidence of treatment-emergent extrapyramidal side effects is lower, and there is less impairment of cognitive function and treatment-related negative symptoms. However, treatment with SGAs has been associated with a wide range of untoward effects, among which treatment-emergent weight gain and metabolic abnormalities are of notable concern. The present clinical review aims to summarize the safety and tolerability profile of selected FGAs and SGAs and to link treatment-related adverse effects to the pharmacodynamic profile of each drug. Evidence, predominantly derived from systematic reviews, meta-analyses, and clinical trials of the drugs amisulpride, aripiprazole, asenapine, brexpiprazole, cariprazine, clozapine, iloperidone, lurasidone, olanzapine, paliperidone, quetiapine, risperidone, sertindole, ziprasidone, CPZ, haloperidol, loxapine, and perphenazine, is summarized. In addition, the safety and tolerability profiles of antipsychotics are discussed in the context of the “behavioral toxicity” conceptual framework, which considers the longitudinal course and the clinical and therapeutic consequences of treatment-emergent side effects. In SMI, SGAs with safer metabolic profiles should ideally be prescribed first. However, alongside with safety, efficacy should also be considered on a patient-tailored basis.

In an effort to regulate physician conflicts of interest, some US academic medical centers (AMCs) enacted policies restricting pharmaceutical representative sales visits to physicians (known as detailing) between 2006 and 2012. Little is known about the effect of these policies on physician prescribing. To analyze the association between detailing policies enacted at AMCs and physician prescribing of actively detailed and not detailed drugs. The study used a difference-in-differences multivariable regression analysis to compare changes in prescribing by physicians before and after implementation of detailing policies at AMCs in 5 states (California, Illinois, Massachusetts, Pennsylvania, and New York) that made up the intervention group with changes in prescribing by a matched control group of similar physicians not subject to a detailing policy. Academic medical center implementation of policies regulating pharmaceutical salesperson visits to attending physicians. The monthly within-drug class market share of prescriptions written by an individual physician for detailed and nondetailed drugs in 8 drug classes (lipid-lowering drugs, gastroesophageal reflux disease drugs, diabetes drugs, antihypertensive drugs, hypnotic drugs approved for the treatment of insomnia [sleep aids], attention-deficit/hyperactivity disorder drugs, antidepressant drugs, and antipsychotic drugs) comparing the 10- to 36-month period before implementation of the detailing policies with the 12- to 36-month period after implementation, depending on data availability. The analysis included 16 121 483 prescriptions written between January 2006 and June 2012 by 2126 attending physicians at the 19 intervention group AMCs and by 24 593 matched control group physicians. The sample mean market share at the physician-drug-month level for detailed and nondetailed drugs prior to enactment of policies was 19.3% and 14.2%, respectively.

The START criteria were applied to detect prescription omission in the geriatric population. We compared the utility of these criteria in institutionalised older people.Methods: Descriptive study reviewing the medication and clinical records of 81 residents (aged 65 years and more by pharmacists in a nursing home in the Lleida region (Spain.Results: The mean patients’ age was 84 (SD=8 years, with an average of 5 drugs per resident (total prescriptions: 416 medicines. The Beers criteria identified potentially inappropriate medication use in 25% of patients and 48% of patients used at least 1 inappropriate medication according to STOPP criteria. The most frequent potentially inappropriate medications for both criteria were long-acting benzodiazepines and NSAIDs. START detected 58 potential prescribing omissions in 44% of patients. Calcium-vitamin D supplementation in osteoporosis was the most frequent rule (15%, but omissions corresponding to the cardiovascular system implied 23% of patients.Conclusion: The STOPP-START criteria reveal that potentially inappropriate prescribing (PIP is a highly prevalent problem among Spanish nursing home residents, and a statistically significant positive correlation was found between the number of medicines prescribed and the number of PIP detected in this study. The STOPP criteria detect a larger number of PI medications in this geriatric population than the Beers criteria. The prescribing omissions detected by the START criteria are relevant and require intervention. Pharmacists’ review of medications may help identify potentially inappropriate prescribing and, through an interdisciplinary approach, working with physicians may improve prescribing practices among geriatric residents of nursing homes.

Implementation of electronic prescribing system can overcome many problems of the paper prescribing system, and provide numerous opportunities of more effective and advantageous prescribing. Successful implementation of such a system requires complete and deep understanding of work content, human force, and workflow of paper prescribing. The current study was designed in order to model the current business process of outpatient prescribing in Iran and clarify different actions during this process. In order to describe the prescribing process and the system features in Iran, the methodology of business process modeling and analysis was used in the present study. The results of the process documentation were analyzed using a conceptual model of workflow elements and the technique of modeling "As-Is" business processes. Analysis of the current (as-is) prescribing process demonstrated that Iran stood at the first levels of sophistication in graduated levels of electronic prescribing, namely electronic prescription reference, and that there were problematic areas including bottlenecks, redundant and duplicated work, concentration of decision nodes, and communicative weaknesses among stakeholders of the process. Using information technology in some activities of medication prescription in Iran has not eliminated the dependence of the stakeholders on paper-based documents and prescriptions. Therefore, it is necessary to implement proper system programming in order to support change management and solve the problems in the existing prescribing process. To this end, a suitable basis should be provided for reorganization and improvement of the prescribing process for the future electronic systems.

There is limited knowledge of the key determinants of antimicrobial prescribing behavior (APB) in hospitals. An understanding of these determinants is required for the successful design, adoption, and implementation of quality improvement interventions in antimicrobial stewardship programs. Qualitative semistructured interviews were conducted with doctors (n = 10), pharmacists (n = 10), and nurses and midwives (n = 19) in 4 hospitals in London. Interviews were conducted until thematic saturation was reached. Thematic analysis was applied to the data to identify the key determinants of antimicrobial prescribing behaviors. The APB of healthcare professionals is governed by a set of cultural rules. Antimicrobial prescribing is performed in an environment where the behavior of clinical leaders or seniors influences practice of junior doctors. Senior doctors consider themselves exempt from following policy and practice within a culture of perceived autonomous decision making that relies more on personal knowledge and experience than formal policy. Prescribers identify with the clinical groups in which they work and adjust their APB according to the prevailing practice within these groups. A culture of "noninterference" in the antimicrobial prescribing practice of peers prevents intervention into prescribing of colleagues. These sets of cultural rules demonstrate the existence of a "prescribing etiquette," which dominates the APB of healthcare professionals. Prescribing etiquette creates an environment in which professional hierarchy and clinical groups act as key determinants of APB. To influence the antimicrobial prescribing of individual healthcare professionals, interventions need to address prescribing etiquette and use clinical leadership within existing clinical groups to influence practice.

For many disorders, patient heterogeneity requires physicians to customize their treatment to each patient's needs. We test for the existence of customization in physicians' prescribing for bipolar disorder, using data from a naturalistic clinical effectiveness trial of bipolar disorder treatment (STEP-BD), which did not constrain physician prescribing. Multinomial logit is used to model the physician's choice among five combinations of drug classes. We find that our observed measure of the patient's clinical status played only a limited role in the choice among drug class combinations, even for conditions such as mania that are expected to affect class choice. However, treatment of a patient with given characteristics differed widely depending on which physician was seen. The explanatory power of the model was low. There was variation within each physician's prescribing, but the results do not suggest a high degree of customization in physicians' prescribing, based on our measure of clinical status.

Nonadherence to the treatment of SMI increases the risk of relapse and hospitalization and reduces the quality of life. It is necessary to understand the factors influencing nonadherence to medication in order to identify appropriate interventions. This systematic review assessed the published evidence on modifiable reasons for nonadherence to antipsychotic medication in patients with SMI. Methods: Articles published between January 1, 2005, and September 10, 2015, were searched on MEDLINE through PubMed. Abstracts were independently screened by 2 randomly assigned authors for inclusion, and disagreement was resolved by another author. Selected full-text articles were divided among all authors for review. Results: A qualitative analysis of data from 36 articles identified 11 categories of reasons for nonadherence. Poor insight was identified as a reason for nonadherence in 55.6% (20/36 of studies, followed by substance abuse (36.1%, 13/36, a negative attitude toward medication (30.5%, 11/36, medication side effects (27.8%, 10/36, and cognitive impairments (13.4%, 7/36. A key reason directly associated with intentional nonadherence was a negative attitude toward medication, a mediator of effects of insight and therapeutic alliance. Substance abuse was the only reason consistently associated with unintentional nonadherence, regardless of type and stage of SMI. Discussion: Although adherence research is inherently biased

Modern antipsychotic drugs are employed increasingly in the treatment of mood disorders as well as psychoses, stimulating interest in their possible contributions to altering suicidal risk. Clozapine remains the only treatment with an FDA-recognized indication for reducing suicidal risk (in schizophrenia). We carried out a systematic, computerized search for reports of studies involving antipsychotic drug treatment and suicidal behaviors. A total of 19 reports provide data with preliminary support for potential suicide risk-reducing effects of olanzapine, quetiapine, ziprasidone, aripiprazole, and asenapine in addition to clozapine, and provide some support for antipsychotic drug treatment in general. These preliminary findings encourage further testing of antipsychotics for effects on suicidal behavior, making use of explicit, pre-planned assessments of suicidal behavior. PMID:27727180

This article suggests that nurse prescribers require an awareness of key concepts in ethics, such as deontology and utilitarianism to reflect on current debates and contribute to them. The principles of biomedical ethics have also been influential in the development of professional codes of conduct. Attention is drawn to the importance of the Association of the British Pharmaceutical Industry's code of practice for the pharmaceutical industry in regulating marketing aimed at prescribers.

Prescribing medication is embedded in social norms and cultures. In modern Western health care professionals and policy makers have attempted to rationalize medicine by addressing cost-effectiveness of diagnostic and therapeutic treatments and the development of guidelines and protocols based on the outcomes of clinical studies. These notions of cost-effectiveness and evidence-based medicine have also been embedded in technology such as electronic prescribing systems. Such constraining systems may clash with the reality of clinical practice, where formal boundaries of responsibility and authorization are often blurred. Such systems may therefore even impede patient care. Medication is seen as the essence of medical practice. Prescribing is a social act. In a hospital medications may be aimed at treating a patient for a specific condition, in primary care the professional often meets the patient with her or his social and cultural notions of a health problem. The author argues that the design and implementation of electronic prescribing systems should address the social and cultural context of prescribing. Especially in primary care, where health problems are often ill defined and evidence-based medicine guidelines do not always work as intended, studies need to take into account the sociotechnical character of electronic prescribing systems.

Non-adherence is a major obstacle to optimal treatment of schizophrenia. Community pharmacists are in a key position to detect non-adherence and put in place interventions. Their role is likely to be more efficient when individuals are loyal to a single pharmacy. To assess the association between the level of community pharmacy loyalty and persistence with and implementation of antipsychotic drug treatment among individuals with schizophrenia. A cohort study using databases from the Quebec health insurance board (Canada) was conducted among new antipsychotic users insured by Quebec's public drug plan. Level of community pharmacy loyalty was assessed as the number of pharmacies visited in the year after antipsychotics initiation. Persistence was defined as having an antipsychotic supply in the user's possession on the 730 th day after its initiation and implementation as having antipsychotics in the user's possession for ≥80% of the days in the second year after antipsychotics initiation (among persistent only). Generalized linear models were used to estimate adjusted prevalence ratios (aPR) and 95% confidence intervals (95%CI). 6,251 individuals were included in the cohort and 54.1% had their drug prescriptions filled in >1 pharmacy. When compared to those who had their prescriptions filled in a single pharmacy, those who had their prescriptions filled in ≥4 different pharmacies were 22% more likely to be non-persistent (aPR = 1.22; 95%CI = 1.10-1.37) and 49% more likely to have an antipsychotic for loyalty in the context of severe mental illness indicates that this healthcare organisation factor might be associated with antipsychotics persistence and implementation. Identification of individuals with low community pharmacy loyalty and initiatives to optimize community pharmacy loyalty could contribute to enhanced persistence and implementation.

Abstract Background Antipsychotic-induced weight gain constitutes a major unresolved clinical problem which may ultimately be associated with reducing life expectancy by 25 years. Overweight is associated with brain deterioration, cognitive decline and poor quality of life, factors which are already compromised in normal weight patients with schizophrenia. Here we outline the current strategies against antipsychotic-induced weight gain, and we describe peripheral and cerebral effects of the g...
Full Text Available Tessa JM Wallace, Clement C Zai, Eva J Brandl, Daniel J MüllerNeurogenetics Section, Center for Addiction and Mental Health, Department of Psychiatry, University of Toronto, Toronto, ON, CanadaAbstract: Antipsychotic-induced weight gain is a serious side effect of antipsychotic medication that can lead to increased morbidity, mortality, and non-compliance in patients. Numerous single nucleotide polymorphisms have been studied for association with antipsychotic-induced weight gain in an attempt to find genetic predictors of this side effect. An ability to predict this side effect could lead to personalized treatment plans for predisposed individuals, which could significantly decrease the prevalence and severity of weight gain. Variations in the serotonin receptor 2c gene (HTR2C have emerged as promising candidates for prediction of antipsychotic-induced weight gain. Specifically, the well-studied -759C/T promoter polymorphism has been associated with weight gain in diverse populations, although some studies have reported no association. This discrepancy is likely due to heterogeneity in study design with respect to ethnicity, treatment duration, and other variables. Notably, the association between HTR2C and antipsychotic-induced weight gain appears strongest in short-term studies on patients with limited or no previous antipsychotic treatment. Other, less extensively studied promoter polymorphisms (-697C/G, -997G/A, and -1165A/G have also emerged as potential predictors of antipsychotic-induced weight gain. Conversely, the well-studied intronic polymorphism Cys23Ser does not appear to be associated. With further research on both HTR2C and other genetic and environmental predictors of antipsychotic-induced weight gain, a predictive test could one day be created to screen patients and provide preventative or alternative treatment for those who are predisposed to this serious side effect.Keywords: HTR2C, pharmacogenomics, promoter polymorphism
Full Text Available Various types of antipsychotics have been developed for the treatment of schizophrenia since the accidental discovery of the antipsychotic activity of chlorpromazine. Although all clinically effective antipsychotic agents have common properties to interact with the dopamine D2 receptor (D2R activation, their precise mechanisms of action remain elusive. Antipsychotics are well known to induce transcriptional changes of immediate early genes (IEGs, raising the possibility that gene expressions play an essential role to improve psychiatric symptoms. Here, we report that while different classes of antipsychotics have complex pharmacological profiles against D2R, they share common transcriptome fingerprint (TFP profile of IEGs in the murine brain in vivo by quantitative real-time PCR (qPCR. Our data showed that various types of antipsychotics with a profound interaction of D2R including haloperidol (antagonist, olanzapine (antagonist, and aripiprazole (partial agonist all share common spatial TFPs closely homologous to those of D2R antagonist sulpiride, and elicited greater transcriptional responses in the striatum than in the nucleus accumbens. Meanwhile, D2R agonist quinpirole and propsychotic NMDA antagonists such as MK-801 and phencyclidine (PCP exhibited the contrasting TFP profiles. Clozapine and propsychotic drug methamphetamine (MAP displayed peculiar TFPs that reflect their unique pharmacological property. Our results suggest that transcriptional responses are conserved across various types of antipsychotics clinically effective in positive symptoms of schizophrenia and also show that temporal and spatial TFPs may reflect the pharmacological features of the drugs. Thus, we propose that a TFP approach is beneficial to evaluate novel drug candidates for antipsychotic development.

Full Text Available Background: Treatment with antipsychotics increases the risk of developing diabetes in patients of schizophrenia but this diabetogenic potential of different antipsychotics seems to be different. Moreover, there may be an independent link between schizophrenia and diabetes. So we plan to study the prevalence of glucose dysregulation in patients of schizophrenia before and after treatment with various antipsychotics. Materials and Methods: Fifty patients (32 males and 18 females diagnosed with schizophrenia were evaluated for glucose dysregulation using oral glucose tolerance test, initially (drug naive and after antipsychotic treatment. Age- and sex-matched healthy volunteer group of 50 subjects (35 males and 15 females was taken for comparison. Results were interpreted using American Diabetic Association criteria. Results: Though the glycemic status of the patient group was comparable with healthy controls initially but antipsychotic treatment was associated with glucose dysregulation. For first 6 weeks the antipsychotic (olanzapine, risperidone, haloperidol and aripiprazole-induced glucose dysregulation was comparable, which was seen to be maximum with the olanzapine-treated group at the end of this study, 14 weeks. Conclusion: We conclude that antipsychotic treatment of nondiabetic drug naive schizophrenia patients was associated with adverse effects on glucose regulation. For initial 6 weeks the antipsychotic-induced glucose dysregulation was comparable, which was seen to be maximum with olanzapine at the end of study, i.e. 14 weeks. Keeping this at the back of mind we can stabilize a patient initially with a more effective drug, olanzapine, and later on shift to one with less metabolic side effects.

Antipsychotic medications are not recommended for the management of symptoms of dementia, particularly among persons with no behavioral or psychological symptoms. We examine patterns of antipsychotic medication use among persons with dementia across health sectors in Canada, with a focus on factors related to use among those without behavioral or psychotic symptoms. Using a retrospective cross-sectional design, this study examines antipsychotic use among adults aged 65 or older with dementia in home care (HC), complex continuing care (CCC), long-term care (LTC), and among alternate level care patients in acute hospitals (ALC). Using clinical data from January 1, 2009 to December 31, 2014, the prevalence of antipsychotic medication use was estimated by the presence of behavioral and psychotic symptoms. Logistic regression was used to identify sector specific factors associated with antipsychotic use in the absence of behavioral and psychotic symptoms. The total prevalence of antipsychotic use among older adults with dementia was 26% in HC, 54% in ALC, 41% in CCC, and 48% in LTC. This prevalence ranged from 38% (HC) to 73% (ALC) for those with both behavioral and psychotic symptoms and from 15% (HC) to 31% (ALC) among those with no symptoms. The regression models identified a number of variables were related to antipsychotic use in the absence of behavior or psychotic symptoms, such as bipolar disorder (OR = 6.63 in CCC; OR = 5.52 in LTC), anxious complaints (OR = 1.54 in LTC to 2.01 in CCC), and wandering (OR = 1.83 in ALC). Potentially inappropriate use of antipsychotic medications is prevalent among older adults with dementia across health sectors. The variations in prevalence observed from community to facility based care suggests that system issues may exist in appropriately managing persons with dementia.
Cost-effectiveness of an atypical conventional antipsychotic in South Africa: An economic evaluation of quetiapine versus haloperidol in the treatment of patients partially responsive to previous antipsychotics
Full Text Available Background. The introduction of a new generation of atypical antipsychotic agents has raised difficult economic and ethical questions, particularly in lower-income countries. The reported tolerability and efficacy advantages of the atypical antipsy- chotics over their conventional predecessors have to be weighed against their higher acquisition costs. Pharmaco-eco- nomic studies conducted in Western countries consistently report cost advantages or cost neutrality for these new agents. However, considerable differences in health care service pro- vision make it difficult to generalise these findings to South Africa. Method. We compared the direct costs (private and public sector of treating schizophrenia with an atypical antipsychotic quetiapine, and with a conventional antipsychotic haloperidol, by adapting a decision-analytic pharmaco-economic model for South African circumstances. The sample comprised patients partially responsive to antipsychotics, who had partic- ipated in a multinational randomised controlled trial compar- ing the efficacy and safety of quetiapine versus haloperidol. Results. The estimated total direct cost for the treatment with quetiapine in South Africa was slightly less than for haloperidol for various models in both the private and the public sectors. Conclusions. Significant differences in health care provision make pharmaco-economic studies conducted in other coun- tries invalid for South African circumstances. Previously queti- apine treatment did not result in direct cost savings in South Africa. However, the recently introduced legislation to estab- lish single exit prices for medications has resulted in the cost of quetiapine treatment declining by 36.7% and that of haloperi- dol by 13%. This has translated into an overall direct cost sav- ing for quetiapine in both the private and public sector models. This, together with additional indirect advantages of the atypi- cal antipsychotics such as improved quality of

Communication skills are known to decrease with advancing cognitive impairment. Analgesic treatment in long-term care may be deficient due to the residents' impaired ability to communicate their pain and needs. Undertreated pain frequently leads to rising BPSD in residents with cognitive impairment, resulting in a treatment with antipsychotics. Aim of this study was the analysis of differences in assessment and pharmacological treatment of pain in nursing home residents relative to their cognitive state and ability to articulate pain. Data stems from the baseline of a non-experimental pre-post-study in 12 Austrian nursing homes. Residents' pain prevalence in relation to pain assessment and cognitive decline was assessed, data on medical diagnoses and prescriptions were retrieved from the nursing homes' documentation (n = 425). Residents were first divided into two groups: Residents with MMSE ≥ 18 were selected into group CUS (cognitively unimpaired/slightly impaired), residents with MMSE ≤ 17 were selected into group CI (cognitively moderately to severely impaired). CI residents were then sub-grouped according to their ability to communicate pain via the Verbal Rating Scale (VRS) (i.e. group CI-V, group CI-NV). Pain behavior of CI residents was assessed with a modified German version of PAINAD. Group differences were tested with ANOVA and H-test, 95 % confidence intervals were calculated and associations were tested with log-binomial regression. Pain prevalence in CI residents irrespective of their ability to communicate pain was 80 % and exceeded the CUS group prevalence significantly by 14 %. CI residents had significantly less analgesic prescriptions. Furthermore, CI residents have a significantly higher risk of getting no analgesics when in pain than CUS residents (CI-V: RR =2.6, CI-NV: RR =3.4). Use of antipsychotics was high in all groups (49 - 65 %) with more prescriptions in the cognitively impaired group. Results point toward an

Full Text Available Case reports in medical literature suggest that the atypical antipsychotic quetiapine, a medication not previously considered to have abuse potential, is now being subject to misuse and abuse (MUA; ie, taken when not prescribed for them or used in a way other than instructed by their health professional. Here we present systematic, nationally representative data from the 2005 to 2011 Drug Abuse Warning Network (DAWN for prevalence of emergency department (ED visits among the U.S. general population involving quetiapine and related to MUA, suicide attempts, and adverse reactions. Nationally, quetiapine-related ED visits increased 90% between 2005 and 2011, from 35,581 ED visits to 67,497. DAWN data indicate that when used without medical supervision for recreational/self-medication purposes, quetiapine poses health risks for its users, especially among polydrug users and women. These findings suggest that the medical and public health communities should increase vigilance concerning this drug and its potential for MUA.

Full Text Available Psychotropic drugs are commonly used to manage mental and behavioral problems in geriatric patients. This is, however, accompanied by the risk of developing adverse drug reactions (ADRs, impacting the safety with which the drug can be used. In this article, we provide an overview of the factors associated with the ADRs due to psychotropic medication in the elderly, and the ADRs associated with the use of antipsychotics and sedative-hypnotics in the geriatric population. For this, literature searches were conducted through MEDLINE, PubMed, and Google Scholar using keyword terms: Geriatric, elderly, safety, adverse events, ADRs, antipsychotic, names of individual antipsychotics, benzodiazepine, sedative, hypnotic, zolpidem, zaleplon, zopiclone. Research data indicate that antipsychotics are associated with an increased risk of metabolic syndrome, thromboembolism, cerebrovascular and cardiac events, pneumonia, fractures, and increased mortality. Among antipsychotics, aripiprazole seems to have fewer ADRs while other antipsychotics (typical and atypicals have reports of troublesome side effect profiles. Sedative-hypnotics are associated with a risk of falls, fractures, cognitive impairment, and may increase the risk of developing dementia with long-term use. The risk of these complications is present with both benzodiazepines and medications such as zolpidem and zopiclone.
Full Text Available Few studies have directly compared atypical antipsychotics (e.g. risperidone with typical antipsychotics as adjunctive therapy in patients hospitalized for acute mania, especially during a lengthy hospital stay. Our retrospective, case-controlled study is a chart review of 64 patients with Diagnostic and Statistical Manual of Mental Disorders, 4th edition, defined bipolar I disorder (current episode, mania. Patients were divided into two groups according to the adjunctive medications used: the risperidone group (mood stabilizers plus risperidone and the control group (mood stabilizers plus typical antipsychotics. Outcome at discharge, medications, adverse drug effects, and length of hospital stay were compared between groups, controlling for gender, age, number of prior admissions, and duration of illness. Results indicated no statistically significant differences between groups in the controlled factors, Global Assessment of Functioning and Clinical Global Impression-Improvement scores, and adverse drug events. Patients in the risperidone group used significantly lower doses of trihexyphenidyl than those in the control group (p < 0.05. Patients treated with risperidone had a shorter hospital stay than those treated with typical antipsychotics (p < 0.01. In conclusion, antipsychotics are effective as adjunctive agents in the treatment of acute mania. The use of risperidone, in particular, decreases the need for anticholinergics and may lead to a shorter hospital stay compared with typical antipsychotics.

Despite consistent recommendations for antipsychotic monotherapy, antipsychotic polypharmacy (the use of two or more antipsychotic agents) and the administration of excessive doses (higher than 1000 mgr/day of chloropromazine equivalents) is a common practice in schizophrenia. The therapeutic and adverse effects of this practice are poorly studied, in particular with regards to the cognitive symptoms of the disease. In this cross-sectional study we investigated the cognitive effects of antipsychotic polypharmacy and excessive doses in 53 patients with chronic schizophrenia using non-verbal cognitive tasks involving speed of movement, memory and executive functions. No significant difference in performance scores was found between the groups under polypharmacy and monotherapy, or the groups receiving either excessive or normal doses of antipsychotics. Since these groups did not also differ in demographic, clinical, other pharmacologic parameters, in the relative anticholinergic potency of antipsychotics, or in intelligence scores, we raise doubts about the association of polypharmacy and excessive doses with non-verbal cognitive performance in chronic schizophrenia.

Atypical antipsychotics have been documented to be effective in the management of delirium in adults, but despite considerable need, their use has been less studied in pediatric patients. A retrospective chart review was done to describe the use of atypical antipsychotics in controlling symptoms of delirium in children and adolescents. Pharmacy records at Children's Hospital Los Angeles were reviewed to identify patients to whom antipsychotic agents were dispensed over a 24-month period. Psychiatric inpatient consultations during the same 24-month period were reviewed. Patients 1-18 years old diagnosed with delirium given antipsychotics constituted the study population. Delirium Rating Scale-Revised-98 (DRS-R98) scores were retrospectively calculated, when possible, at time antipsychotic was started to confirm the initial diagnosis of delirium and evaluate symptom severity, and again when antipsychotic was stopped, to assess symptom response. Olanzapine (n=78), risperidone (n=13), and quetiapine (n=19) were used during the 2 years of the study. Mean patient age, length of treatment, and response were comparable for the three medications. For patients with two DRS-R98 scores available (n=75/110), mean DRS-R98 scores decreased significantly (pdelirium symptoms in pediatric patients while underlying etiology was addressed.

Hyperfunction of brain dopamine (DA) systems is associated with psychosis in schizophrenia and the medications used to treat schizophrenia are DA receptor blockers. DA also plays a critical role in incentive learning produced by rewarding stimuli. Using DA as the link, these results suggest that psychosis in schizophrenia can be understood from the point of view of excessive incentive learning. Incentive learning is mediated through the non-declarative memory system and may rely on the striatum or medial prefrontal cortex depending on the task. Typical and atypical antipsychotics differentially affect expression of the immediate early gene c-fos, producing greater activity in the striatum and medial prefrontal cortex, respectively. This led to the hypothesis that performance of schizophrenic patients on tasks that depend on the striatum or medial prefrontal cortex will be differentially affected by their antipsychotic medication. Results from a number of published papers supported this dissociation. Furthermore, the effects of two atypical drugs, clozapine and olanzapine, on c-fos expression were different from another atypical, risperidone that resembles the typical antipsychotics. Similarly, in tests of incentive learning, risperidone acted like the typical antipsychotics. Thus, typical and atypical antipsychotic drugs differed in the types of cognitive performance they affected and, furthermore, members of the atypical class differed in their effects on cognition. It remains the task of researchers and clinicians to sort out the symptoms associated with the endogenous illness from possible iatrogenic symptoms resulting from the antipsychotic medications used to treat schizophrenia.

Full text: The comprehensive evaluation of medical residents in a residency-training program includes the use of educational tools to measure the attainment of competencies in the cognitive, psychomotor and affective domains as prescribed in the training curriculum. Attention is almost always focused on the testing of cognitive domain of the learners with limited attention given on the psychomotor and affective parameters, which are in fact, together with the cognitive domain, integral to the students' learning behaviour. This paper aims to review the principles of test construction, including the perspectives on the roles, types and purpose of tests in the domains of learning (cognitive, psychomotor and affective) as well as the use of Non-Test materials for measuring affective learning outcomes and the construction of Performance Tests and Portfolio Assessment tools which are all essential for the effective and efficient evaluation of residents in a Nuclear Medicine Training Program.

Full Text Available JP LindenmayerDepartment of Psychiatry, New York University School of Medicine, New York NY, USAAbstract: Medication non-adherence in patients with schizophrenia continues to be a significant problem and threatens successful treatment outcomes. Medication non-adherence is often associated with negative consequences, including symptom exacerbation, more frequent emergency room visits, re-hospitalizations and relapse. Long-acting injectable (LAI forms of antipsychotics allow for rapid identification of non-adherence, obviate the need for the patient to take the medication on a daily basis and increase adherence to some significant degree. Eli Lilly has developed a long-acting depot formulation of olanzapine, olanzapine pamoate, which has recently been approved by the FDA for the US market, and which will be reviewed here. Olanzapine LAI appears to be an effective antipsychotic at dosages of 210 mg every 2 weeks, 300 mg every 2 weeks and 405 mg every 4 weeks in patients with acute schizophrenia, and at 150 mg every 2 weeks, 300 mg every 2 weeks and at 405 mg every 4 weeks for the maintenance treatment of stable patients. Oral supplementation appears not to be needed, particularly not at the onset of treatment with the LAI as is necessary with risperidone LAI. Its efficacy is in general comparable to the efficacy seen with oral olanzapine at a corresponding dose. The side effect profile is also comparable to the side effects observed with oral olanzapine, including lower rates of extrapyramidal symptoms, prolactin elevation and cardiovascular side effects, but significant metabolic effects. The latter include significant weight gain, lipid abnormalities and glucose dysregulation. While the injection site adverse events are overall mild, the most significant serious adverse event is the post-injection delirium sedation syndrome (PDSS. While rare, this syndrome results from inadvertent intravascular injection of olanzapine LAI and can cause a range of

Air pollution events associated with wildfires have been associated with extreme health impacts. Prescribed burns are an important tool to reduce the severity of wildfires. However, if undertaken during unfavourable meteorological conditions, they too have the capacity to trigger extreme air pollution events. The Australian state of New South Wales has increased the annual average area treated by prescribed burn activities by 45%, in order to limit wildfire activity. Prescribed burns need to be undertaken during meteorological conditions that allow the fuel load to burn, while still allowing the burn to remain under control. These conditions are similar to those that inhibit atmospheric dispersion, resulting in a fine balance between managing fire risk and managing ambient air pollution. During prescribed burns, the Sydney air shed can experience elevated particulate matter concentrations, especially fine particulates (PM2.5) that occasionally exceed national air quality standards. Using pollutant and meteorological data from sixteen monitoring stations in Sydney we used generalized additive model and CART analyses to profile the meteorological conditions influencing air quality during planned burns. The insights gained from this study will help improve prescribed burn scheduling in order to reduce the pollution risk to the community, while allowing fire agencies to conduct this important work.

Prescribed burning has primarily been used as a tool for the control of invasive late-season annual broadleaf and grass species, particularly yellow starthistle, medusahead, barb goatgrass, and several bromes. However, timely burning of a few invasive biennial broadleaves (e.g., sweetclover and garlic mustard), perennial grasses (e.g., bluegrasses and smooth brome), and woody species (e.g., brooms and Chinese tallow tree) also has been successful. In many cases, the effectiveness of prescribed burning can be enhanced when incorporated into an integrated vegetation management program. Although there are some excellent examples of successful use of prescribed burning for the control of invasive species, a limited number of species have been evaluated. In addition, few studies have measured the impact of prescribed burning on the long-term changes in plant communities, impacts to endangered plant species, effects on wildlife and insect populations, and alterations in soil biology, including nutrition, mycorrhizae, and hydrology. In this review, we evaluate the current state of knowledge on prescribed burning as a tool for invasive weed management.

Nursing residents may experience physical and emotional exhaustion from the daily life of attending the Program. The aim of this study was to determine the Burnout incidence among Nursing Residents. An investigative, descriptive, analytical, longitudinal-prospective study was conducted with 16 Residents over two years. The Maslach Burnout Inventory was used, translated and validated for Brazil, as well as a sociodemographic/occupational data tool. Of all residents, 17.2% showed high rates in Emotional Exhaustion and Depersonalization; 18.8% showed impaired commitment in Personal Accomplishment, 75% of which belonged to specialty areas, such as Emergency Nursing, Adult and Pediatric Intensive Care. Age and specialty area were positively correlated with Personal Accomplishment. One of the Residents was identified with changes in three subscales of the Maslach Burnout Inventory, thus characterized as a Burnout Syndrome patient. Nursing Residents have profiles of disease. Knowing these factors can minimize health risks of these workers.

Despite concerns about rising treatment of young people with antipsychotic medications, little is known about trends and patterns of their use in the United States. To describe antipsychotic prescription patterns among young people in the United States, focusing on age and sex. A retrospective descriptive analysis of antipsychotic prescriptions among patients aged 1 to 24 years was performed with data from calendar years 2006 (n = 765,829), 2008 (n = 858,216), and 2010 (n = 851,874), including a subset from calendar year 2009 with service claims data (n = 53,896). Data were retrieved from the IMS LifeLink LRx Longitudinal Prescription database, which includes approximately 60% of all retail pharmacies in the United States. Denominators were adjusted to generalize estimates to the US population. The percentage of young people filling 1 or more antipsychotic prescriptions during the study year by sex and age group (younger children, 1-6 years; older children, 7-12 years; adolescents, 13-18 years; and young adults, 19-24 years) was calculated. Among young people with antipsychotic use, percentages with specific clinical psychiatric diagnoses and 1 or more antipsychotic prescriptions from a psychiatrist and from a child and adolescent psychiatrist were also determined. The percentages of young people using antipsychotics in 2006 and 2010, respectively, were 0.14% and 0.11% for younger children, 0.85% and 0.80% for older children, 1.10% and 1.19% for adolescents, and 0.69% and 0.84% for young adults. In 2010, males were more likely than females to use antipsychotics, especially during childhood and adolescence: 0.16% vs 0.06% for younger children, 1.20% vs 0.44% for older children, 1.42% vs 0.95% for adolescents, and 0.88% vs 0.81% for young adults. Among young people treated with antipsychotics in 2010, receiving a prescription from a psychiatrist was less common among younger children (57.9%) than among other age groups (range, 70.4%-77.9%). Approximately 29.3% of
Full Text Available For decades, there have been observations demonstrating significant metabolic disturbances in people with schizophrenia including clinically relevant weight gain, hypertension, and disturbances in glucose and lipid homeostasis. Many of these findings pre-date the use of antipsychotic drugs (APDs which on their own are also strongly associated with metabolic side effects. The combination of APD-induced metabolic changes and common adverse environmental factors associated with schizophrenia have made it difficult to determine the specific contributions of each to the overall metabolic picture. Data from drug-naïve patients, both from the pre-APD era and more recently, suggest that there may be an intrinsic metabolic risk associated with schizophrenia. Nevertheless, these findings remain controversial due to significant clinical variability in both psychiatric and metabolic symptoms throughout patients' disease courses. Here, we provide an extensive review of classic and more recent literature describing the metabolic phenotype associated with schizophrenia. We also suggest potential mechanistic links between signaling pathways associated with schizophrenia and metabolic dysfunction. We propose that, beyond its symptomatology in the central nervous system, schizophrenia is also characterized by pathophysiology in other organ systems directly related to metabolic control.

Surveillance of physicians' prescribing patterns and the accumulation and sale of these data for pharmaceutical marketing are currently the subjects of legislation in several states and action by state and national medical associations. Contrary to common perception, the growth of the health care information organization industry has not been limited to the past decade but has been building slowly over the past 50 years, beginning in the 1940s when growth in the prescription drug market fueled industry interest in understanding and influencing prescribing patterns. The development of this surveillance system was not simply imposed on the medical profession by the pharmaceutical industry but was developed through the interactions of pharmaceutical salesmen, pharmaceutical marketers, academic researchers, individual physicians, and physician organizations. Examination of the role of physicians and physician organizations in the development of prescriber profiling is directly relevant to the contemporary policy debate surrounding this issue.

The general perceptions of prescribed burning were elicited from forest users for an area that has been subject to this form of land management for at least 20 years. The largest group consisted of local residents living in and around the Wombat State Forest with two smaller groups of students from a nearby university campus and local professional land managers. A questionnaire was given to each participant in order to explore how the forest was used, to determine the level of knowledge of burning in the targeted forest and Victoria and the perception of the appearance, effectiveness of protection, and accessibility to the forest after prescribed burning. Generally all groups had similar responses with community members having stronger views on the effectiveness and practicalities of prescribed burning, whereas students were more neutral in their opinions. All participants claimed knowledge of prescribed burning activities within Victoria, but fewer had experience of planned fires in the Wombat State Forest. All groups agreed that areas that had not been recently burned had a better appearance than those that had, but this result may have included a range of value judgments. Land managers had a greater understanding of the ecological importance of season and timing of burning; however, some students and community members were equally knowledgeable. Prescribed burning did not impede access to the forest, nor did smoke from prescribed burns pose any great problem. The majority of the participants felt that the amount of prescribed burning done in the forest was adequate for engendering a feeling of protection to life and property, yet many were still suspicious of this management practice. These initial findings indicate several areas in which further research would be useful including the efficacy of education programs for community members and improved communication of burn plans by land managers.

Numerous large observational studies have shown an increased risk of mortality in elderly users of conventional antipsychotics. Health authorities have warned against use of these drugs. However, terminal illness is a potentially strong confounder of the observational findings. So, the objective of this study was to systematically assess whether terminal illness may have biased the observational association between conventional antipsychotics and risk of mortality in elderly patients. Studies were searched in PubMed, CINAHL, Embase, the references of selected studies and articles referring to selected studies (Web of Science). Inclusion criteria were (i) observational studies that estimated (ii) the risk of all-cause mortality in (iii) new elderly users of (iv) conventional antipsychotics compared with atypical antipsychotics or no use. Two investigators assessed the characteristics of the exposure and reference groups, main results, measured confounders and methods used to adjust for unmeasured confounders. We identified 21 studies. All studies were based on administrative medical and pharmaceutical databases. Sicker and older patients received conventional antipsychotics more often than new antipsychotics. The risk of dying was especially high in the first month of use, and when haloperidol was administered per injection or in high doses. Terminal illness was not measured in any study. Instrumental variables that were used were also confounded by terminal illness. We conclude that terminal illness has not been adjusted for in observational studies that reported an increased risk of mortality risk in elderly users of conventional antipsychotics. As the validity of the evidence is questionable, so is the warning based on it. Copyright © 2015 John Wiley & Sons, Ltd.

Tourette's syndrome (TS) is a neuropsychiatric disorder of childhood onset characterized by multiple motor and phonic tics that fluctuate over time. Tic symptoms often improve by late adolescence, but some children and adults with TS may experience significant tic-related morbidity, including social and family problems, academic difficulties, and pain. When more conservative interventions are not successful, and when certain psychiatric co-morbidities further complicate the clinical profile, treating TS with an atypical antipsychotic medication may be a reasonable second-tier approach. However, the evidence supporting efficacy and safety of the atypical antipsychotics for treatment of tics is still very limited. The objective of this paper is to provide an updated overview of the role of atypical antipsychotics for treatment of TS, with evidence-based guidance on their use. Evidence for efficacy of different typical and atypical antipsychotics for treatment of tics was examined by conducting a systematic, keyword-related search of 'atypical antipsychotics' and 'Tourette's syndrome' in PubMed (National Library of Medicine, Washington, DC, USA). Four recent treatment consensus publications were also reviewed. This review focused on literature published from 2000 to 2013 and on available randomized controlled trials in TS. Evidence supporting the use of atypical antipsychotics for treatment of TS is limited. There are few randomized medication treatment trials in TS (i.e. risperidone, aripiprazole, ziprasidone), which employed varying methodologies, thereby restricting meaningful comparisons among studies. Future collaborations among clinical sites with TS expertise employing high-quality study design may better elucidate the role of atypical antipsychotics for treatment of TS.

To determine the most adequate strategies for the prevention and treatment of the acute adverse effects of the use of antipsychotics. A clinical practice guideline was elaborated under the parameters of the Methodological Guide of the Ministerio de Salud y Protección Social to identify, synthesize and evaluate the evidence and make recommendations about the treatment and follow-up of adult patients with schizophrenia. A systematic literature search was carried out. The evidence was presented to the Guideline Developing Group and recommendations, employing the GRADE system, were produced. The non-pharmacological interventions such as nutritional counseling by a nutritionist, exercise and psychotherapy are effective in preventing weight gain with the use of antipsychotics. (Kg Weight reduction in DM of -3.05 (-4.16, -1.94)). The antipsychotic change from olanzapine to aripiprazole showed weight loss and decreased BMI (decreased weight in KG DM -3.21 (-9.03, -2.61). The use of beta blockers was ineffective in reducing akathisia induced by antipsychotic; using as outcome the 50% reduction of symptoms of akathisia comparing beta-blockers with placebo RR was 1.4 (0.59, 1.83). It is recommended to make psychotherapeutic accompaniment and nutrition management of overweight for patients with weight gain. If these alternatives are ineffective is suggested to change the antipsychotic or consider starting metformin. For the management of drug-induced akathisia it is recommended to decrease the dose of the drug and the addition of lorazepam. It is recommended using 5mg biperiden IM or trihexyphenidyl 5mg orally in case of secondary acute dystonia and for the treatment of antipsychotic-induced parkinsonism to decrease the dose of antipsychotic or consider using 2 - 4mg/day of biperiden or diphenhydramine 50mg once daily.

Preparing medical students to prescribe is a major challenge of undergraduate education. They must develop an understanding of clinical pharmacology and acquire knowledge about drugs and therapeutics, as well as the skills to prescribe for individual patients in the face of multiple variables. The task of delivering the learning required to achieve these attributes relies upon limited numbers of teachers, who have increasingly busy clinical commitments. There is evidence that training is currently insufficient to meet the demands of the workplace. e-Learning provides an opportunity to improve the learning experience. The advantages for teachers are improved distribution of learning content, ease of update, standardization and tracking of learner activities. The advantages for learners are ease of access, greater interactivity and individual choice concerning the pace and mix of learning. Important disadvantages are the considerable resource required to develop e-Learning projects and difficulties in simulating some aspects of the real world prescribing experience. Pre-requisites for developing an e-Learning programme to support prescribing include academic expertise, institutional support, learning technology services and an effective virtual learning environment. e-Learning content might range from complex interactive learning sessions through to static web pages with links. It is now possible to simulate and provide feedback on prescribing decisions and this will improve with advances in virtual reality. Other content might include a student formulary, self-assessment exercises (e.g. calculations), a glossary and an on-line library. There is some evidence for the effectiveness of e-Learning but better research is required into its potential impact on prescribing. © 2012 The Authors.

Single cell stimulation in vivo is a powerful tool to investigate the properties of single neurons and their functionality in neural networks. We present a method to determine a cell-specific stimulus that reliably evokes a prescribed spike train with high temporal precision of action potentials. We test the performance of this stimulus in simulations for two different stochastic neuron models. For a broad range of parameters and a neuron firing with intermediate firing rates (20-40 Hz) the reliability in evoking the prescribed spike train is close to its theoretical maximum that is mainly determined by the level of intrinsic noise.

Full Text Available Background: A number of case reports have suggested a possible association between atypical antipsychotic medications and hyponatremia. Currently, there are no reliable estimates of hyponatremia risk from atypical antipsychotic drugs. Objective: The objective of this study was to examine the 30-day risk of hospitalization with hyponatremia in older adults dispensed an atypical antipsychotic drug relative to no antipsychotic use. Design: The design of this study was a retrospective, population-based cohort study. Setting: The setting of this study was in Ontario, Canada, from 2003 to 2012. Patients: Adults 65 years or older with an identified psychiatric condition who were newly dispensed risperidone, olanzapine, or quetiapine in the community setting compared to adults with similar indicators of baseline health who were not dispensed such a prescription. Measurements: The primary outcome was the 30-day risk of hospitalization with hyponatremia. The tracer outcome (an outcome that is not expected to be influenced by the study drugs was the 30-day risk of hospitalization with bowel obstruction. These outcomes were assessed using hospital diagnosis codes. Methods: Using health administrative data, we applied a propensity score technique to match antipsychotic users 1:1 to non-users of antipsychotic drugs (58,008 patients in each group. We used conditional logistic regression to compare outcomes among the matched users and non-users. Results: A total of 104 baseline characteristics were well-balanced between the two matched groups. Atypical antipsychotic use compared to non-use was associated with an increased risk of hospitalization with hyponatremia within 30 days (86/58,008 (0.15 % versus 53/58,008 (0.09 %; relative risk 1.62 (95 % confidence interval (CI 1.15 to 2.29; absolute risk increase 0.06 % (95 % CI 0.02 to 0.10. The limited number of events precluded some additional analyses to confirm if the association was robust. Atypical

Background The trend towards increased psychotropic drug prescribing in children and adolescents is well recognised in North America and continental Europe. However, it is unclear to what extent these studies are applicable to clinical practice in the United Kingdom (UK). This study was conducted to estimate the prevalence of psychotropic drug prescribing in children and adolescents aged <19 years in general practice in the UK from January 1992 to December 2001. Methods Data were obtained from the General Practice Research Database (GPRD). Annual age- and sex-specific prevalence of psychotropic drug prescribing was calculated. Results A total of 143,079 prescriptions were issued to 34,398 study subjects. Stimulant prescriptions rose significantly from 0.03 per 1,000 (95% confidence interval 0.02-0.04) in 1992 to 2.9 per 1,000 (2.52-3.32) in 2001; a 96-fold increase. Methylphenidate accounted for the majority of stimulant prescriptions; 2.4% (349/14,370) of stimulant prescriptions were prescribed to children aged <6 years. Increased prescribing was also noted for antidepressants (1.6-fold), hypnotics/anxiolytics (1.3-fold), antipsychotics (1.3-fold) and anticonvulsants (1.3-fold), whilst the prevalence of clonidine and lithium prescribing remained fairly stable throughout the study period. The use of antidepressant, hypnotic/anxiolytic and anticonvulsant increased with increasing age. A high proportion of boys received stimulants, whereas antidepressants and hypnotics/anxiolytics were more likely prescribed to girls. Conclusion There is an increased trend of psychotropic drug use in children and adolescents in the UK practice. Since most psychotropic drugs are not licensed for use in children at this time, research is needed to investigate the efficacy and long-term safety in this population
Full Text Available Excess body weight is one of the most common physical health problems among patients with schizophrenia that increases the risk for many medical problems, including type 2 diabetes mellitus, coronary heart disease, osteoarthritis, and hypertension, and accounts in part for 20% shorter life expectancy than in general population. Among patients with severe mental illness, obesity can be attributed to an unhealthy lifestyle, personal genetic profile, as well as the effects of psychotropic medications, above all antipsychotic drugs. Novel “atypical” antipsychotic drugs represent a substantial improvement on older “typical” drugs. However, clinical experience has shown that some, but not all, of these drugs can induce substantial weight gain. Animal models of antipsychotic-related weight gain and animal transgenic models of knockout or overexpressed genes of antipsychotic receptors have been largely evaluated by scientific community for changes in obesity-related gene expression or phenotypes. Moreover, pharmacogenomic approaches have allowed to detect more than 300 possible candidate genes for antipsychotics-induced body weight gain. In this paper, we summarize current thinking on: (1 the role of polymorphisms in several candidate genes, (2 the possible roles of various neurotransmitters and neuropeptides in this adverse drug reaction, and (3 the state of development of animal models in this matter. We also outline major areas for future research.
Background Antipsychotic-induced weight gain constitutes a major unresolved clinical problem which may ultimately be associated with reducing life expectancy by 25 years. Overweight is associated with brain deterioration, cognitive decline and poor quality of life, factors which are already compromised in normal weight patients with schizophrenia. Here we outline the current strategies against antipsychotic-induced weight gain, and we describe peripheral and cerebral effects of the gut hormone glucagon-like peptide-1 (GLP-1). Moreover, we account for similarities in brain changes between schizophrenia and overweight patients. Discussion Current interventions against antipsychotic-induced weight gain do not facilitate a substantial and lasting weight loss. GLP-1 analogs used in the treatment of type 2 diabetes are associated with significant and sustained weight loss in overweight patients. Potential effects of treating schizophrenia patients with antipsychotic-induced weight gain with GLP-1 analogs are discussed. Conclusions We propose that adjunctive treatment with GLP-1 analogs may constitute a new avenue to treat and prevent metabolic and cerebral deficiencies in schizophrenia patients with antipsychotic-induced weight gain. Clinical research to support this idea is highly warranted. PMID:22891821

The authors investigated the extent to which clinical diagnoses of externalizing disorders explain higher rates of antipsychotic use by foster care youths. Medicaid claims data from 44 states for 2009 for youths in foster care (N=301,894) and those not in foster care (N=5,092,574) were analyzed, excluding those with schizophrenia, bipolar disorder, autism, and major depressive disorder. Logistic regressions assessed the relationship between foster care, externalizing disorders, and antipsychotic use. Foster care youths had higher rates of externalizing disorders than the comparison group (attention-deficit hyperactivity disorder, 17.3% versus 6.5%; disruptive behavior disorder, 7.2% versus 2.5%; conduct disorder, 2.3% versus .5%) and greater antipsychotic use (7.4% versus 1.4%). Foster care remained a significant predictor of antipsychotic use after control for demographic and diagnostic covariates, including externalizing disorders (adjusted odds ratio=2.59, 95% confidence interval=2.54-2.63). High rates of externalizing disorder diagnoses only partially explained elevated levels of antipsychotic use in this vulnerable population.
Full Text Available Schizophrenia is one of mental disorders with high cost and lifetime morbidity risk. Hence, it is necessary to analyze the cost-effectiveness of various combinations of antipsychotics. The aim of this study was to analyze the most cost-effective group of antipsychotic combinations in schizophrenia inpatients in West Java Psychiatric Hospital during 2012–2013. Data were collected retrospectively from medical record of patients who used antipsychotics clozapine-haloperidol or clozapine-risperidone therapy. Direct medical costs were obtained from antipsychotics costs, costs of medical treatment, medical expenses, hospitalization costs, and administrative costs. The results showed that the average cost-effectiveness ratio of antipsychotic clozapine-haloperidol was Rp126.898/day and Rp132.781/day for the combination of clozapine-haloperidol and clozapine-risperidone, respectively. Considering length of stay as the therapy effectiveness, it can be concluded that the combination of clozapine-haloperidol is more cost-effective than clozapine-risperidone.

Cannabidiol (CBD), a non-psychotomimetic compound of the Cannabis sativa, has been reported to have central therapeutic actions, such as antipsychotic and anxiolytic effects. We have recently reported that Spontaneously Hypertensive Rats (SHRs) present a deficit in social interaction that is ameliorated by atypical antipsychotics. In addition, SHRs present a hyperlocomotion that is reverted by typical and atypical antipsychotics, suggesting that this strain could be useful to study negative symptoms (modeled by a decrease in social interaction) and positive symptoms (modeled by hyperlocomotion) of schizophrenia as well as the effects of potential antipsychotics drugs. At the same time, an increase in social interaction in control animals similar to that induced by benzodiazepines is used to screen potential anxiolytic drugs. The aim of this study was to investigate the effects of CBD on social interaction presented by control animals (Wistar) and SHRs. The lowest dose of CBD (1mg/kg) increased passive and total social interaction of Wistar rats. However, the hyperlocomotion and the deficit in social interaction displayed by SHRs were not altered by any dose of CBD. Our results do not support an antipsychotic property of cannabidiol on symptoms-like behaviors in SHRs but reinforce the anxiolytic profile of this compound in control rats.

Major depressive disorder (MDD) is a common condition with a lifetime prevalence of 15% to 18%, which leads to considerable suffering and disability. Some antipsychotics have been reported to induce remission in major depression, when added to an antidepressant. To evaluate the effects of second-generation antipsychotic (SGA) drugs (alone or augmentation) compared with placebo or antidepressants for people with MDD or dysthymia. The Cochrane Depression, Anxiety and Neurosis Group's controlled trial registers (CCDANCTR-Studies and CCDANCTR-References) were searched up to 21 July 2010. The author team ran complementary searches on clinicaltrials.gov and contacted key authors and drug companies. We included all randomised, double-blind trials comparing oral SGA treatment (alone or augmentation) with other forms of pharmaceutical treatment or placebo in people with MDD or dysthymia. We extracted data independently. For dichotomous data we calculated the odds ratio (OR) and 95% confidence interval (CI) on an intention-to-treat basis, and for continuous data the mean difference (MD), based on a random-effects model. We presented each comparison separately; we did not perform a pooled data analysis. We included 28 trials with 8487 participants on five SGAs: amisulpride, aripiprazole, olanzapine, quetiapine and risperidone.Three studies (1092 participants) provided data on aripiprazole augmentation in MDD. All efficacy data (response n = 1092, three RCTs, OR 0.48; 95% CI 0.37 to 0.63), (MADRS n = 1077, three RCTs, MD -3.04; 95% CI -4.09 to -2) indicated a benefit for aripiprazole but more side effects (weight gain, EPS) .Seven trials (1754 participants) reported data on olanzapine. Compared to placebo fewer people discontinued treatment due to inefficacy; compared to antidepressants there were no efficacy differences, olanzapine augmentation showed symptom reduction (MADRS n = 808, five RCTs, MD -2.84; 95% CI -5.48 to -0.20), but also more weight or prolactin increase

E-prescribing is part of a new generation of electronic solutions for the medical industry that may have great potential for improving work flow and communication between medical practices and pharmacies. In the US, it has been introduced with minimal monitoring of errors and general usability. This paper examines refill functionality in e-prescribing software. A mixed method study including focus groups and surveys was conducted. Qualitative data were collected in on-site focus groups or individual interviews with clinicians and medical office staff at 64 physician office practices. Focus group participants described their experiences with the refill functionality of e-prescribing software, provided suggestions for improving it, and suggested improvements in office procedures and software functionality. Overall, approximately 50% reduction in time spent each day on refills was reported. Overall reports of refill functionality were positive; but clinicians and staff identified numerous difficulties and glitches associated managing prescription refills. These glitches diminished over time. Benefits included time saved as well as patient convenience. Potential for refilling without thought because of the ease of use was noted. Clinicians and staff appreciated the ability to track whether patients are filling and refilling prescriptions. E-prescribing software for managing medication refills has not yet reached its full potential. To reduce work flow barriers and medication errors, software companies need to develop error reporting systems and response teams to deal effectively with problems experienced by users. Examining usability issues on both the medical office and pharmacy ends is required to identify the behavioral and cultural changes that accompany technological innovation and ease the transition to full use of e-prescribing software. 2010 Elsevier Ireland Ltd.

In response to a perceived erosion of medical dermatology, combined internal medicine and dermatology programs (med/derm) programs have been developed that aim to train dermatologists who take care of medically complex patients. Despite the investment in these programs, there is currently no data with regards to the potential impact of these trainees on the dermatology workforce. To determine the experiences, motivations, and future plans of residents in combined med/derm residency programs. We surveyed residents at all United States institutions with both categorical and combined training programs in spring of 2012. Respondents used visual analog scales to rate clinical interests, self-assessed competency, career plans, and challenges. The primary study outcomes were comfort in taking care of patients with complex disease, future practice plans, and experience during residency. Twenty-eight of 31 med/derm residents (87.5%) and 28 of 91 (31%) categorical residents responded (overall response rate 46%). No significant differences were seen in self-assessed dermatology competency, or comfort in performing inpatient consultations, cosmetic procedures, or prescribing systemic agents. A trend toward less comfort in general dermatology was seen among med/derm residents. Med/derm residents were more likely to indicate career preferences for performing inpatient consultation and taking care of medically complex patients. Categorical residents rated their programs and experiences more highly. Med/derm residents have stronger interests in serving medically complex patients. Categorical residents are more likely to have a positive experience during residency. Future work will be needed to ascertain career choices among graduates once data are available.

Falls continue to be a problem for older people in long-term care (LTC) and retirement home (RH) settings and are associated with significant morbidity and health care use. Fall-risk increasing drugs (FRIDs) are known to increase fall risk and represent modifiable risk factors. There are limited data regarding the use of FRIDs in contemporary LTC and RH settings, and it has not been well documented to what extent medication regimens are reviewed and modified for those who have sustained falls. The objective of this study is to characterize medication related fall risk factors in LTC and RH residents and on-going use of medications known to increase fall risk. Retrospective chart review of residents aged >65 who sustained one or more falls living in LTC or RH settings. 105 residents who fell one or more times during 2009-2010 were identified with a mean age of 89 years, a mean of nine scheduled medications and seven diagnoses, and 83% were women. Residents in LTC were ostensibly at higher risk for falls relative to those in RH settings as suggested by higher proportion of residents with multiple falls, multiple comorbidities, comorbidities that increase fall risk and visual impairment. Post fall injuries were sustained by 42% of residents, and residents in RH sustained more injuries relative to LTC residents (47 vs 34%). Use of FRIDs such as benzodiazepines, antipsychotic, antidepressant and various antihypertensive drugs was common in the present sample. No medication regimen changes were noted in the 6-month post fall period. The present study documented common use FRIDs by LTC and RH residents with multiple falls. These potentially modifiable falls risk factors are not being adequately addressed in contemporary practice, demonstrating that there is much room for improvement with regards to the safe and appropriate use of medications in LTC and RH residents.

In two recent randomised clinical trials, a meta-analysis and in an effectiveness study analysing routine data from the U.S. Veterans Administration the superiority of the newer atypical drugs over typical antipsychotic drugs, concerning both their efficacy and their side-effect profile, has been questioned. To analyse the effectiveness and cost of atypical versus typical antipsychotic treatment for schizophrenia in routine care. Cohort study using routine care data from a statutory sickness fund with 5.4 million insured in Germany. To be included, patients had to be discharged with a diagnosis of schizophrenia in 2003 and fulfil membership criteria. Main outcome measures were rehospitalisation rates, mean hospital bed days, mean length of stay, cost of inpatient and pharmaceutical care to the sickness fund during follow-up and medication used to treat side-effects. 3121 patients were included into the study. There were no statistically significant differences in the effectiveness of atypical and typical antipsychotics on rehospitalisation during follow-up (rehospitalisation rate ratio 1.07, 95% confidence interval 0.86 to 1.33). However, there were consistent observations of atypical antipsychotics being more effective for severe cases of schizophrenia (14.6% of study population; >61 prior bed days per year in 2000-2002) in the follow-up period, whereas for the other severity strata typical antipsychotics seemed more effective in reducing various rehospitalisation outcomes. Patients treated with atypical antipsychotics received significantly less prescriptions for anticholinergics or tiaprid (relative risk 0.26, 95% confidence interval 0.18 to 0.38). The effectiveness of atypical antipsychotics for schizophrenia on rehospitalisation measures appeared similar to that of typical antipsychotics. With the exception of severe cases, the higher costs for atypical antipsychotics were not offset by savings from reduced inpatient care. Major limitations include the lack of

between schizophrenia and overweight patients. DISCUSSION: Current interventions against antipsychotic-induced weight gain do not facilitate a substantial and lasting weight loss. GLP-1 analogues used in the treatment of type 2 diabetes are associated with significant and sustained weight loss...... are already compromised in normal weight patients with schizophrenia. Here we outline the current strategies against antipsychotic-induced weight gain, and we describe peripheral and cerebral effects of the gut hormone glucagon-like peptide-1 (GLP-1). Moreover, we account for similarities in brain changes...... in overweight patients. Potential effects of treating schizophrenia patients with antipsychotic-induced weight gain with GLP-1 analogues are discussed. CONCLUSIONS: We propose that adjunctive treatment with GLP-1 analogues may constitute a new avenue to treat and prevent metabolic and cerebral deficiencies...

Full Text Available Objectives: To describe a case of neuroleptic malignant syndrome following antipsychotic treatment of catatonia, highlighting the potentially serious complications of this rare adverse drug reaction. Methods: We present a case report of a patient who developed this syndrome with various sequelae. Results: The patient developed neuroleptic after being treated with lorazepam and olanzapine for catatonia. He subsequently developed the complications of rhabdomyolysis, acute kidney injury, pulmonary embolism, urinary retention and ileus. He received high-dose lorazepam, anticoagulation and intravenous fluids. Antipsychotic medication in the form of haloperidol was reinstated with no adverse effect, and he went on to make a full recovery. Conclusions: This case illustrates the potential life-threatening complications of neuroleptic malignant syndrome and the need for a low index of clinical suspicion. It also highlights the lack of evidence for treatment of catatonia, including the use of antipsychotics.

Patients with schizophrenia have a higher mortality risk than patients suffering from any other psychiatric disorder. Previous research is inconclusive regarding the association of antipsychotic treatment with long-term mortality risk. To this aim, we systematically reviewed the literature and performed a meta-analysis on the relationship between long-term mortality and exposure to antipsychotic medication in patients with schizophrenia. The objectives were to (i) determine long-term mortality rates in patients with schizophrenia using any antipsychotic medication; (ii) compare these with mortality rates of patients using no antipsychotics; (iii) explore the relationship between cumulative exposure and mortality; and (iv) assess causes of death. We systematically searched the EMBASE, MEDLINE and PsycINFO databases for studies that reported on mortality and antipsychotic medication and that included adults with schizophrenia using a follow-up design of more than 1 year. A total of 20 studies fulfilled our inclusion criteria. These studies reported 23,353 deaths during 821,347 patient years in 133,929 unique patients. Mortality rates varied widely per study. Meta-analysis on a subgroup of four studies showed a consistent trend of an increased long-term mortality risk in schizophrenia patients who did not use antipsychotic medication during follow-up. We found a pooled risk ratio of 0.57 (LL:0.46 UL:0.76 p value schizophrenia without antipsychotic medication require further research. Prospective validation studies, uniform measures of antipsychotic exposure and classified causes of death are commendable.

Rationale: Occupancy of dopamine D-2 receptors by antipsychotic drugs depends on the individual availability of D-2 receptors and on the dose and type of antipsychotic medication. It has been suggested that a low availability of these receptors may increase the risk for addictive behavior.

However, the bulk of the research has yielded results that are often inconsistent. In this prospective, observational study, we assessed the measurement properties of 3 commonly used, pharmacy-based measures of treatment adherence with antipsychotic agents in schizophrenia using data from the Veterans Health Administration during 2000 to 2005. Patients were selected if they were on antipsychotics and diagnosed with schizophrenia (N = 18,425. A gap of ≥30 days (with no filled index medication was used to define discontinuation of treatment as well as medication “episodes,” or the number of times a patient returned to the same index agent after discontinuation of treatment within a 1-year period. The study found that the 3 existing measures differed in their approaches in measuring treatment adherence, suggesting that studies using these different measures would generate different levels of treatment adherence across antipsychotic agents. Considering the measurement problems associated with each existing approach, we offered a new, medication episode-specific approach, which would provide a fairer comparison of the levels of treatment adherence

In a randomised controlled trial, patients were offered financial incentives to improve their adherence to anti-psychotic maintenance medication. Compared to a control group without the incentives, they had an improved adherence and also better subjective quality of life (SQOL) after 1 year. This paper explores the question as to whether this improvement in SQOL was associated with the amount of money received or with the improved adherence itself. A secondary analysis was performed using data of the experimental group in the trial. Adherence was assessed as the percentage of all prescribed long-acting anti-psychotic injections that were taken by the patient. In regression models, we tested whether changes in medication adherence and/or the amount of incentives received over the 12-month period was associated with SQOL, as rated on the DIALOG scale. Adherence changed from 68.49 % at baseline to 88.23 % (mean difference in adherence = 19.59 %, SD = 17.52 %). The total amount of incentives received within the 1-year study period varied between £75 and £735, depending on the treatment cycle and the number of long-acting injections taken. Improvement in adherence was found to be a significant predictor of better subjective quality of life (β = 0.014, 95 % CI 0.003-0.025, p = 0.014), whilst the amount of incentives received was not (β = 0.0002, 95 % CI -0.002 to 0.002, p = 0.818). Improved medication adherence is associated with a more favourable SQOL. This underlines the clinical relevance of improved adherence in response to financial incentives in this patient group.

To test the effect of a nurse-led intervention on weight gain in people with serious mental illness prescribed and taking second generation antipsychotic medication. Weight gain and obesity has reached epidemic proportions in the general population with the prevalence of Metabolic Syndrome reaching 20-25% of the global population. People with serious mental illness are at even higher risk, particularly those taking second generation antipsychotic medication. An experimental randomized controlled trial was undertaken. The control group received a 12-week healthy lifestyle booklet. In addition to the booklet, the intervention group received weekly nutrition and exercise education, exercise sessions, and nurse support. Participants (n = 101) were assessed at baseline and 12 weeks. Data were collected between March 2008-December 2010. Seven outcome measures were used: body measurements included girth (cm), weight (kg), height (cm), and body mass index (kg/m(2) ); questionnaires included the medication compliance questionnaire, the Drug Attitude Inventory, the Liverpool University Neuroleptic Side Effect Rating Scale, and the Medical Outcomes Study Short Form 36. Differences in primary outcome measures between baseline and 12 weeks follow-up were compared between intervention and control groups using standard bi-variate statistical tests. The study was conducted between 2008-2010. The analysis of outcome measures for the control group (n = 50) and intervention group (n = 51) was not statistically significant. There was a mean weight change of -0·74 kg at 12 weeks for the intervention group (n = 51), while the control group (n = 50) had a mean weight change of -0·17 kg at 12 weeks. The results were not statistically significant. © 2012 Blackwell Publishing Ltd.

A randomized controlled trial 'Money for Medication'(M4M) was conducted in which patients were offered financial incentives for taking antipsychotic depot medication. This study assessed the attitudes and ethical considerations of patients and clinicians who participated in this trial. Three mental healthcare institutions in secondary psychiatric care in the Netherlands participated in this study. Patients (n = 169), 18-65 years, diagnosed with schizophrenia, schizoaffective disorder or another psychotic disorder who had been prescribed antipsychotic depot medication, were randomly assigned to receive 12 months of either treatment as usual plus a financial reward for each depot of medication received (intervention group) or treatment as usual alone (control group). Structured questionnaires were administered after the 12-month intervention period. Data were available for 133 patients (69 control and 64 intervention) and for 97 clinicians. Patients (88%) and clinicians (81%) indicated that financial incentives were a good approach to improve medication adherence. Ethical concerns were categorized according to the four-principles approach (autonomy, beneficence, non-maleficence, and justice). Patients and clinicians alike mentioned various advantages of M4M in clinical practice, such as increased medication adherence and improved illness insight; but also disadvantages such as reduced intrinsic motivation, loss of autonomy and feelings of dependence. Overall, patients evaluated financial incentives as an effective method of improving medication adherence and were willing to accept this reward during clinical treatment. Clinicians were also positive about the use of this intervention in daily practice. Ethical concerns are discussed in terms of patient autonomy, beneficence, non-maleficence and justice. We conclude that this intervention is ethically acceptable under certain conditions, and that further research is necessary to clarify issues of benefit

Long-acting injectable (LAI) antipsychotics improve treatment outcomes in patients with schizophrenia but are often reserved for only the most severely affected or nonadherent. Studies show cultural/racial differences in prescribing. This pilot study examined prescriber-patient interactions and cultural/racial differences in perceptions of LAIs among patients. A linguist analyzed 120 prescriber-patient conversations representing selected patient cultural/racial subgroups (European American, African American, Latino American; n=40 each) to identify similarities and differences in conceptualization and attitudes toward LAIs. Of 35 LAI-naive patients offered LAIs, 9% (3/35) responded favorably, 46% (16/35) were neutral/passive, and 46% (16/35) had concerns or viewed LAIs as unfavorable. Among LAI-naive patients, favorable or neutral/passive responses were reported for 50% (7/14) of European Americans, 63% (10/16) of African Americans, and 40% (2/5) of Latino Americans. The majority of LAI-naive patients (57% [20/35]) accepted LAI prescriptions, including 53% (17/32) of those who initially were neutral/passive or refused treatment (European American, 42% [5/12]; African American, 53% [8/15]; Latino American, 80% [4/5]). Fifty-seven percent (68/120) of patients expressed treatment goals. Goals of positive/negative symptom control were associated with positive attitudes toward LAIs while patients with goals focused on control of anxiety and insomnia tended to have negative attitudes toward LAIs. Latino-American patients who expressed treatment goals seemed more focused on discomfort control (67% [12/18]); goals of European Americans and African Americans were more equally distributed. Equal numbers of LAI-naive patients had unfavorable/concerned or neutral/passive attitudes toward treatment; relatively few patients responded favorably. The limited sample size precludes cultural/racial-specific conclusions.

In this naturalistic study we investigated a sample of 809 antipsychotic-treated patients from Swedish psychosis outpatient teams. Cardiovascular risk factors (eg, metabolic syndrome, homeostasis model assessment of insulin resistance, and low-density lipoprotein values were measured, and their associations to current antipsychotic pharmacotherapy were studied. Ten antipsychotic drugs were compared in a stepwise logistic regression model. For the patients, the presence of the components of metabolic syndrome ranged from 35% for hyperglycemia to 64% for elevated waist circumference.

Formal nutrition training in medical schools and residencies is lacking and needed. Registered dietitians (RDs) are formally trained in nutrition support and considered experts in the nutrition field. Our purpose was to examine prescribing and recommending discrepancies of parenteral nutrition macronutrients between medical residents (MRs) and RDs and compare results with the ASPEN clinical care guidelines. We also looked at discrepancies among obese patients, due to their increased risk of mortality. The primary end point of this retrospective review was discrepancies in nonprotein calories (NPCs) and grams of protein (PRO) between MRs and RDs. The secondary end point was discrepancies in NPCs and PRO between MRs and RDs among patients stratified by body mass index category. MRs prescribed 300 NPCs more versus RDs ( P < .001). When compared with RDs, MRs prescribed fewer NPCs for underweight patients and more for obese patients ( P < .001). The same analysis found that the PRO discrepancies significantly varied by body mass index classification as well ( P = .022). When these results were compared with the ASPEN clinical care guidelines, RDs adhered closer to the guidelines than did MRs in terms of permissive underfeeding of obese patients. It is widely accepted that MRs are in need of increased formal training, and the results of our study confirm this need and suggest a short-term solution of increasing order-writing privileges for the RD. RDs with this privilege may adhere more closely to clinical care guidelines and therefore increase patient safety.

E-learning is increasingly used in education on antimicrobial stewardship, but participation rates are often low. Insight into factors that affect participation is therefore needed. Autonomous motivation is associated with higher achievements in medical education and could also play a role in e-learning participation. We therefore aimed to investigate the role of residents' autonomous motivation in their participation in e-learning on antibiotic prescribing. We performed a multicentre cohort study in two academic and two teaching hospitals. Residents who filled out questionnaires on antibiotic knowledge, the perceived importance of antibiotics and motivation [Self-Regulation Questionnaire - Academic (SRQ-a)] received e-learning access. We used the SRQ-a to calculate relative autonomous motivation (RAM), an index that estimates the amount of autonomous motivation compared with the amount of controlled motivation. We then analysed associations between RAM and participation in e-learning with logistic regression. Eighty-six residents participated (74% female, mean age 30 years). Overall e-learning participation was 58% (n = 50). Participation was 41% in residents with negative RAM (i.e. more controlled motivation) and 62% in residents with positive RAM (i.e. more autonomous motivation). RAM was positively associated with participation, adjusted for residency in an academic hospital (adjusted OR 2.6, 95% CI 1.5-4.6). Participation in non-obligatory e-learning on antibiotic prescribing is higher in residents with more autonomous motivation. Interventions to increase autonomous motivation could improve participation. Preceding e-learning on antibiotic prescribing with face-to-face education, to explain the importance of the subject, could enhance autonomous motivation and thus optimize e-learning efficiency.

Antipsychotic adjunctive therapy to mood stabilizers (MSs) may improve relapse prevention; however, only a few naturalistic studies, reflecting more generalizable bipolar disorder (BD) samples, support this notion. We compared the 1-year rehospitalization rates of manic patients with bipolar I disorder (BD-I) who were discharged with MS (lithium or valproate) monotherapy or with adjunctive atypical or typical antipsychotic therapy. A total of 201 patients with BD-I who were hospitalized with manic episodes between 2005 and 2013 were retrospectively followed for 1-year rehospitalization rates according to treatment at discharge: MS monotherapy, MS with atypical antipsychotics, and MS with typical antipsychotics. Additionally, time to rehospitalization during the 1-year period after discharge was compared between treatment groups. Multivariable survival analyses adjusted for covariates known to influence rehospitalization were conducted. Rehospitalization rates within 1 year were significantly lower in the MS with atypical antipsychotics group (6.3%) compared to the MS monotherapy group (24.3%, P=.008) and to the MS with typical antipsychotics group (20.6%, P=.02). Time to rehospitalization was significantly longer for the MS with atypical antipsychotics group (345.5 days) compared to the MS monotherapy group (315.1 days, P=.006) and to the MS with typical antipsychotics group (334.1 days, P=.02). The MS with atypical antipsychotics group had a significantly reduced adjusted risk of rehospitalization (hazard ratio=0.17, 95% confidence interval: 0.05-0.61, P=.007) compared to the MS monotherapy group. Atypical antipsychotic adjunctive therapy to MSs may be more effective than MS monotherapy in preventing rehospitalization during the 1-year period after a BD manic episode. © 2016 John Wiley & Sons A/S.

Consistent with past research, antipsychotic polypharmacy was defined as the concurrent use of olanzapine and another antipsychotic for at least 60 days. Switching was defined as discontinuing a prior antipsychotic therapy rather than augmenting the medication regimen. Predictors of antipsychotic monotherapy were based on information available at the time of olanzapine initiation. Baseline characteristics were compared using t-tests and Χ2 tests. Stepwise logistic regression was used to identify independent predictors of monotherapy.Results: Patients treated with olanzapine monotherapy (43.2% differed from those treated with antipsychotic polypharmacy (56.8% on demographics, treatment history, baseline symptom levels, functional levels, and treatment-emergent adverse events.

Full Text Available Purpose: Recent studies have established the association between hypotonic fluids administration and hospital-acquired hyponatremia in children, and have contended that hypotonic fluids be removed from routine practice. To assess current intravenous fluid prescription practices among Korean pediatric residents and to call for updated clinical-practice education Methods: A survey-based analysis was carried out. Pediatric residents at six university hospitals in Korea completed a survey consisting of four questions. Each question supposed a unique scenario in which the respondents were to prescribe either a hypotonic or an isotonic fluid for the patient. Results: Ninety-one responses were collected and analyzed. In three of the four scenarios, a significant majority prescribed the hypotonic fluids (98.9%, 85.7%, and 69.2%, respectively. Notably, 69.2% of the respondents selected the hypotonic fluids for postoperative management. Almost all (96.7% selected the isotonic fluids for hydration therapy. Conclusion: In the given scenarios, the majority of Korean pediatric residents would prescribe a hypotonic fluid, except for initial hydration. The current state of pediatric fluid management, notably, heightens the risk of hospital-acquired hyponatremia. Updated clinical practice education on intravenous fluid prescription, therefore, is urgently required.

The circumstances surrounding the deaths of 75 asthmatic patients who had been prescribed a domiciliary nebuliser driven by an air compressor pump for administration of high dose beta sympathomimetic drugs were investigated as part of the New Zealand national asthma mortality study. Death was judged unavoidable in 19 patients who seemed to have precipitous attacks despite apparently good long term management. Delays in seeking medical help because of overreliance on beta agonist delivered by nebuliser were evident in 12 cases and possible in a further 11, but these represented only 8% of the 271 verified deaths from asthma in New Zealanders aged under 70 during the period. Evidence for direct toxicity of high dose beta agonist was not found. Nevertheless, the absence of serum potassium and theophylline concentrations and of electrocardiographic monitoring in the period immediately preceding death precluded firm conclusions whether arrhythmias might have occurred due to these factors rather than to hypoxia alone. In most patients prescribed domiciliary nebulisers death was associated with deficiencies in long term and short term care similar to those seen in patients without nebulisers. Discretion in prescribing home nebulisers, greater use of other appropriate drugs, including adequate corticosteroids, and careful supervision and instruction of patients taking beta agonist by nebuliser should help to reduce the mortality from asthma.

Section 190 of the Clean Air Act (CAA) as amended in 1990 requires the US Environmental Protection Agency (EPA) to issue guidance on Best Available Control Measures (BACM) of PM 10 (particulate matter with a nominal aerodynamic diameter less than or equal to 10 micrometers) from urban fugitive dust, residential wood combustion, and prescribed silvicultural and agricultural burning (prescribed burning). The purpose of this guidance is to assist states (especially, but not exclusively, those with PM 10 nonattainment areas which have been classified as serious) in developing a control measure for these three source categories. This guidance is to be issued no later than May 15, 1992 as required under the CAA. The guidance will be issued in the form of a policy guidance generic to all three BACM and in the form of Technical Information Documents (TIDs) for each of the three source categories. The policy guidance will provide the analytical approach for determining BACM and the TID will provide the technical information. The purpose of this paper is to present some insight from the forthcoming TID on what BACM might entail for prescribed burning in a serious PM 10 nonattainment area

To examine the relationship between certified nursing assistant (CNA) training requirements and resident outcomes in U.S. nursing homes (NHs). The number and type of training hours vary by state since many U.S. states have chosen to require additional hours over the federal minimums, presumably to keep pace with the increasing complexity of care. Yet little is known about the impact of the type and amount of training CNAs are required to have on resident outcomes. Compiled data on 2010 state regulatory requirements for CNA training (clinical, total initial training, in-service, ratio of clinical to didactic hours) were linked to 2010 resident outcomes data from 15,508 NHs. Outcomes included the following NH Compare Quality Indicators (QIs) (Minimum Data Set 3.0): pain, antipsychotic use, falls with injury, depression, weight loss and pressure ulcers. Facility-level QIs were regressed on training indicators using generalized linear models with the Huber-White correction, to account for clustering of NHs within states. Models were stratified by facility size and adjusted for case-mix, ownership status, percentage of Medicaid-certified beds and urban-rural status. A higher ratio of clinical to didactic hours was related to better resident outcomes. NHs in states requiring clinical training hours above federal minimums (i.e., >16hr) had significantly lower odds of adverse outcomes, particularly pain falls with injury, and depression. Total and in-service training hours also were related to outcomes. Additional training providing clinical experiences may aid in identifying residents at risk. This study provides empirical evidence supporting the importance of increased requirements for CNA training to improve quality of care. © The Author 2016.

Full Text Available Abstract Background The United States (US Health Information Technology for Economic and Clinical Health Act of 2009 has spurred adoption of electronic health records. The corresponding meaningful use criteria proposed by the Centers for Medicare and Medicaid Services mandates use of computerized provider order entry (CPOE systems. Yet, adoption in the US and other Western countries is low and descriptions of successful implementations are primarily from the inpatient setting; less frequently the ambulatory setting. We describe prescriber and staff perceptions of implementation of a CPOE system for medications (electronic- or e-prescribing system in the ambulatory setting. Methods Using a cross-sectional study design, we conducted eight focus groups at three primary care sites in an independent medical group. Each site represented a unique stage of e-prescribing implementation - pre/transition/post. We used a theoretically based, semi-structured questionnaire to elicit physician (n = 17 and staff (n = 53 perceptions of implementation of the e-prescribing system. We conducted a thematic analysis of focus group discussions using formal qualitative analytic techniques (i.e. deductive framework and grounded theory. Two coders independently coded to theoretical saturation and resolved discrepancies through discussions. Results Ten themes emerged that describe perceptions of e-prescribing implementation: 1 improved availability of clinical information resulted in prescribing efficiencies and more coordinated care; 2 improved documentation resulted in safer care; 3 efficiencies were gained by using fewer paper charts; 4 organizational support facilitated adoption; 5 transition required time; resulted in workload shift to staff; 6 hardware configurations and network stability were important in facilitating workflow; 7 e-prescribing was time-neutral or time-saving; 8 changes in patient interactions enhanced patient care but required education; 9 pharmacy
Full Text Available Abstract Background Mental illness is highly prevalent among prisoners. Although psychotropic medicines can ameliorate symptoms of mental illness, prescribers in prisons must balance clinical needs against risks to safety and security. Concerns have been raised at the large number of prisoners reportedly receiving psychotropic medicines in England. Nonetheless, unlike for the wider community, robust prescribing data are not routinely available for prisons. We investigated gender-specific patterns in the prevalence and appropriateness of psychotropic prescribing in English prisons. Methods We studied 6052 men and 785 women in 11 prisons throughout England. This represented 7.9 % of male and 20.5 % of female prisoners nationally. Using a cross-sectional design, demographic and prescription data were collected from clinical records of all prisoners prescribed psychotropic medicines, including hypnotic, anxiolytic, antipsychotic, anti-manic, antidepressant and Central Nervous System stimulant medications. Percentages and 95 % CIs were used to estimate the prevalence of prescribing. The Prescribing Appropriate Indicators tool was used to determine appropriateness. Prevalence Ratios (PR were generated to make age-adjusted comparisons between prisoners and the general population using a dataset supplied by the Clinical Practice Research Datalink. Results Overall, 47.9 % (CI 44.4–51.4 of women and 16.9 % (CI 16.0–17.9 of men in prison were prescribed one or more psychotropic medicines. Compared with the general population, age-adjusted prescribing prevalence was six times higher among women (PR 5.95 CI 5.36–6.61 and four times higher among men (PR 4.02 CI 3.75–4.30. Undocumented or unapproved indications for prescriptions, not listed in the British National Formulary, were recorded in a third (34.7 %, CI 32.5–37.0 of cases, most commonly low mood and personality disorder.

The aim of this study is identified the degree of Burnout Syndrome (BOS) and find out its correlation with years of recidency and sociodemograpfic chareacteristics, training, sleeping habits, such as smoking and alcohol consumption. After approval from the Hospital Ethics Committee and obtaining informed consent, First, second, third, fourth and fifth year of recidency staff (n=127) working in our hospital were involved in this study. The standardized Maslach Burnout Inventory (MBI) was used in this study. Fifty six male (44.1%) and seventy one female (55.9%) residents were enroled in this study (Coranbach Alfa(α)=0.873). 57% of the first year residents smokes cigaret and 54% of them use alcohol. 2% of them gets one day off after hospital night shift, 61% of them suffers from disturbed sleep. 60% of them had been stated that they willingly selected their profession. 61% of them prefers talking to friends and 32% of them prefers shopping to overcome stress. There were statistical difference acording to years of recidency in MBI, Emotional Burnout (EB) and desensitisation scale (DS) points. EB scale points of the second year of residency group was statisticaly higher than fourth year of residency group. DS points of second year of residency group was also statisticaly higher than the third and fourth year of residency group. There was no statistical difference between any groups in Personal Success. BOS is a frequent problem during residency in anaesthesia. Appropriate definition and awareness are the first important steps to prevent this syndrome. Further administrative approaches should be evaluated with regard to their effects.

Drug overdose is the leading cause of injury death in the United States. The death rate from drug overdose in the United States more than doubled during 1999-2013, from 6.0 per 100,000 population in 1999 to 13.8 in 2013. The increase in drug overdoses is attributable primarily to the misuse and abuse of prescription drugs, especially opioid analgesics, sedatives/tranquilizers, and stimulants. Such drugs are prescribed widely in the United States, with substantial variation by state. Certain patients obtain drugs for nonmedical use or resale by obtaining overlapping prescriptions from multiple prescribers. The risk for overdose is directly associated with the use of multiple prescribers and daily dosages of >100 morphine milligram equivalents (MMEs) per day. 2013. The Prescription Behavior Surveillance System (PBSS) is a public health surveillance system that allows public health authorities to characterize and quantify the use and misuse of prescribed controlled substances. PBSS began collecting data in 2012 and is funded by CDC and the Food and Drug Administration. PBSS uses standard metrics to measure prescribing rates per 1,000 state residents by demographic variables, drug type, daily dose, and source of payment. Data from the system can be used to calculate rates of misuse by certain behavioral measures such as use of multiple prescribers and pharmacies within specified time periods. This report is based on 2013 de-identified data (most recent available) that represent approximately one fourth of the U.S. Data were submitted quarterly by prescription drug monitoring programs (PDMPs) in eight states (California, Delaware, Florida, Idaho, Louisiana, Maine, Ohio, and West Virginia) that routinely collect data on every prescription for a controlled substance to help law enforcement and health care providers identify misuse or abuse of such drugs. In all eight states, opioid analgesics were prescribed approximately twice as often as stimulants or benzodiazepines
Full Text Available Objective: To determine the prescribing patterns of family medicine residents for patients aged more than 60 years with 2 or more chronic diseases and seen at least twice in a 12 month timeframe.Methods: This is a descriptive analysis which was based on chart reviews. The setting was the University of Illinois-Rockford Family Practice Residency. Patients aged 60 years with 2 or more chronic diseases who were seen at least twice by second and third year residents.Results: Findings from this chart review include: 28.8% of the prescribed medications were not effective for the documented condition, 26.3% of the prescribed doses were incorrect, and 44.5% of the drugs prescribed were not the least expensive alternative.Discussion: This preliminary study suggests a need for a focused intervention with family medicine residents regarding inappropriate polypharmacy issues with older patients.
Full Text Available No abstract available. Article truncated at 150 words. The most important time in a physician’s educational development is residency, especially the first year. However, residency work and responsibility have come under the scrutiny of a host of agencies and bureaucracies, and therefore, is rapidly changing. Most important in the alphabet soup of regulatory agencies is the Accreditation Council for Graduate Medical Education (ACGME which accredits residencies and ultimately makes the governing rules.Resident work hours have received much attention and are clearly decreasing. However, the decline in work hours began in the 1970’s before the present political push to decrease work hours. The residency I entered in 1976 had every third night call during the first year resident’s 6-9 months on general medicine or wards. It had changed from every other night the year before. On wards, we normally were in the hospital for our 24 hours of call and followed this with a 10-12 hour day before …

Full Text Available ABSTRACT Vascular cognitive impairment (VCI is a common condition in which no standard treatment has been approved. VCI is often accompanied by behavioral problems which require psychiatric interventions. The common therapeutic agent used for the acute management is antipsychotic injections. Current findings showed that atypical antipsychotic possess better safety profile for treating behavioral problems related to VCI compared to typical antipsychotic. In this study, we induced VCI in Sprague Dawley rats between 6-8 weeks old using bilateral carotid communist artery occlusion technique. The subjects were divided into 4 treatment groups: sham, olanzapine, haloperidol, and risperidone groups. Subjects received intramuscular injections of subsequent drugs for 3 days post VCI induction. Impulsive behavior and object recognition were examined using cliff jumping test and novel object recognition test. The analyses results showed that impulsive behavior was lower in the olanzapine and haloperidol groups compared to sham group, although it was not statistically significant (p = 0.651. The results also showed that there were no significant differences in the time spent exploring old and novel objects in all groups (p = 0.945;0.637 respectively. In conclusion, antipsychotic injection might not be effective to control impulsive behavior post VCI induction.

Concern has been recently raised for risperidone and olanzapine, possibly associated with cerebrovascular events in placebo-controlled trials conducted in elderly subjects with dementia. We investigated the relationship between exposure to second-generation antipsychotics (SGAs) and occurrence of cerebrovascular accidents in the elderly. From the regional database of hospital admissions of Lombardy, Italy, we extracted all patients aged 65 or older with cerebrovascular-related outcomes for the year 2002. From the regional database of prescriptions reimbursed by the National Health Service, we extracted all patients aged 65 or older who received antipsychotic prescriptions during 2001. The 2 databases were linked anonymously using the individual patient code. The proportions of cerebrovascular accidents were 3.31% (95% confidence interval, 2.95-3.69) in elderly subjects exclusively exposed to SGAs and 2.37% (95% confidence interval, 2.19-2.57) in elderly subjects exclusively exposed to first-generation antipsychotics. After background group differences were controlled for, exposure to SGAs significantly increased the risk of accidents. The analysis of cerebrovascular events in elderly subjects exposed to each individual SGA, in comparison with exposure to haloperidol, showed a significantly increased risk for risperidone only (adjusted odds ratio, 1.43; 95% confidence interval, 1.12-1.93). These data provide preliminary epidemiological evidence that exposure to SGAs, in comparison with exposure to first-generation antipsychotics, significantly increased the risk of cerebrovascular accidents in the elderly.

Full Text Available Antipsychotics are often used in conjunction with anti-Alzheimer drugs to treat the behavioral and psychological symptoms of dementia (BPSD. Here, we examined the effects of cholinesterase inhibitors (ChEIs, donepezil and galantamine, on antipsychotic-induced extrapyramidal side effects (EPS in mice. The effects of serotonergic agents on the EPS drug interaction were also evaluated. Donepezil (0.3–3 mg/kg did not induce EPS signs by itself; however, it significantly potentiated bradykinesia induction with a low dose of haloperidol (0.5 mg/kg in dose-dependent and synergistic manners. Galantamine (0.3–3 mg/kg elicited mild bradykinesia at a high dose and dose-dependently augmented haloperidol-induced bradykinesia. The EPS potentiation by galantamine was blocked by trihexyphenidyl (a muscarinic antagonist, but not by mecamylamine (a nicotinic antagonist. In addition, the bradykinesia potentiation by galantamine was significantly reduced by (±-8-hydroxy-2-(di-n-propylamino-tetralin (a 5-HT1A agonist, ritanserin (a 5-HT2 antagonist, and SB-258585 (a 5-HT6 antagonist. The present results give us a caution for the antipsychotics and ChEIs interaction in inducing EPS in the treatment of BPSD. In addition, second generation antipsychotics, which can stimulate 5-HT1A receptors or antagonize 5-HT2 and 5-HT6 receptors, seem to be favorable as an adjunctive therapy for BPSD.

This study aimed to investigate the association of multiple candidate genes with weight gain and appetite change during antipsychotic treatment. A total of 233 single nucleotide polymorphisms (SNPs) within 60 candidate genes were genotyped. BMI changes for up to 8 weeks in 84 schizophrenia patients receiving antipsychotic medication were analyzed using a linear mixed model. In addition, we assessed appetite change during antipsychotic treatment in a different group of 46 schizophrenia patients using the Drug-Related Eating Behavior Questionnaire. No SNP showed a statistically significant association with BMI or appetite change after correction for multiple testing. We observed trends of association (PGHRL showed suggestive evidence of association with not only weight gain (P=0.001) but also appetite change (P=0.042). Patients carrying the GG genotype of rs696217 exhibited higher increase in both BMI and appetite compared to patients carrying the GT/TT genotype. Our findings suggested the involvement of a GHRL polymorphism in weight gain, which was specifically mediated by appetite change, during antipsychotic treatment in schizophrenia patients. © Georg Thieme Verlag KG Stuttgart · New York.

Accumulating evidence suggest a life-long impact of disease related mechanisms on brain structure in schizophrenia which may be modified by antipsychotic treatment. The aim of the present study was to investigate in a large sample of patients with schizophrenia the effect of illness duration and antipsychotic treatment on brain structure. Seventy-one schizophrenic patients and 79 age and gender matched healthy participants underwent brain magnetic resonance imaging (MRI). All images were processed with voxel based morphometry, using SPM5. Compared to healthy participants, patients showed decrements in gray matter volume in the left medial and left inferior frontal gyrus. In addition, duration of illness was negatively associated with gray matter volume in prefrontal regions bilaterally, in the temporal pole on the left and the caudal superior temporal gyrus on the right. Cumulative exposure to antipsychotics correlated positively with gray matter volumes in the cingulate gyrus for typical agents and in the thalamus for atypical drugs. These findings (a) indicate that structural abnormalities in prefrontal and temporal cortices in schizophrenia are progressive and, (b) suggest that antipsychotic medication has a significant impact on brain morphology.

Atypical antipsychotics generally have milder side-effects than conventional antipsychotics, but also differ among themselves in this respect. This study aimed to compare the impact of different side-effect profiles of individual atypical antipsychotics on non-compliance, relapse and cost in schizophrenia. A state-transition model was built using literature data supplemented by expert opinion. The model found that quetiapine and ziprasidone were similar in estimated non-compliance and relapse rates. Olanzapine and risperidone had higher estimated non-compliance and relapse rates, and incremental, 1-year, per-patient direct costs, using US-based cost data, of approximately $530 (95% confidence interval [CI] approximately $275, $800), and approximately $485 (95% CI approximately $235, $800), respectively, compared with quetiapine. Incremental costs attributable to different side-effect profiles were highly significant. This study shows that differing side-effect profiles of the newer antipsychotic agents are likely to lead to different compliance rates, and consequent variation in relapse rates. The cost implications of these heterogenous clinical outcomes are substantial.

Glycogen synthase kinase-3 (GSK3) has been recognized as an important enzyme that modulates many aspects of neuronal function. Accumulating evidence implicates abnormal activity of GSK3 in mood disorders and schizophrenia, and GSK3 is a potential protein kinase target for psychotropics used in these disorders. We previously reported that serotonin, a major neurotransmitter involved in mood disorders, regulates GSK3 by acutely increasing its N-terminal serine phosphorylation. The present study was undertaken to further determine if atypical antipsychotics, which have therapeutic effects in both mood disorders and schizophrenia, can regulate phospho-Ser-GSK3 and inhibit its activity. The results showed that acute treatment of mice with risperidone rapidly increased the level of brain phospho-Ser-GSK3 in the cortex, hippocampus, striatum, and cerebellum in a dose-dependent manner. Regulation of phospho-Ser-GSK3 was a shared effect among several atypical antipsychotics, including olanzapine, clozapine, quetiapine, and ziprasidone. In addition, combination treatment of mice with risperidone and a monoamine reuptake inhibitor antidepressant imipramine or fluoxetine elicited larger increases in brain phospho-Ser-GSK3 than each agent alone. Taken together, these results provide new information suggesting that atypical antipsychotics, in addition to mood stabilizers and antidepressants, can inhibit the activity of GSK3. These findings may support the pharmacological mechanisms of atypical antipsychotics in the treatment of mood disorders.

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.

Also, the questionnaire assessed any perceived deficiencies in their undergraduate clinical pharmacology teaching and sought feedback regarding improvement in the teaching.Results: Eighty-eight percent of residents said that they were taught prescription writing in undergraduate pharmacology teaching; 48% of residents rated their prescribing knowledge at graduation as average, 28% good, 4% excellent, 14% poor, and 4% very poor; 58% felt that their undergraduate training did not prepare them to prescribe safely, and 62% felt that their training did not prepare them to prescribe rationally. Fifty-eight percent of residents felt that they had some specific problems with writing a prescription during their internship training, while 92% thought that undergraduate teaching should be improved. Their suggestions for improving teaching methods were recorded.Conclusions: This study concludes that efforts are needed to develop a curriculum that encompasses important aspects of clinical pharmacology and therapeutics along with incorporation of

Full Text Available Background. Despite recommendations by guidelines to avoid combinations of antipsychotics unless after multiple trials of antipsychotic monotherapy, it is quite a common practice to use combinations. This practice leads to unnecessary expenses and exposes the patient to severe drug adverse effects. Methods. An institution based cross-sectional study was conducted from April to May 2014. Systematic random sampling technique was used to select 423 study subjects. Logistic regression analysis was conducted to identify associated factors of antipsychotic polypharmacy among schizophrenia outpatients. Result. The overall prevalence of antipsychotic polypharmacy was found to be 28.2%. Extra pyramidal side effects (AOR = 2.80; 95% CI: 1.38, 5.71, repeated psychiatric hospitalization (AOR = 2.83; 95% CI: 1.45, 5.50, history of substance use (AOR = 2.82; 95% CI: 1.36, 5.88, longer duration of treatment (AOR = 2.10; 95% CI: 1.14, 3.87, and drug nonadherence (AOR = 1.84; 95% CI: 1.14, 2.98 were found to be significantly associated with antipsychotic polypharmacy. Conclusion. Prevalence of antipsychotic polypharmacy was found to be high among the current study participants. Individuals who had extra pyramidal side effects, admission, substance use, duration of treatment, and drug nonadherence were associated with antipsychotic polypharmacy.

Pituitary volume was measured from T1-weighted magnetic resonance images in a group of 43 first-episode psychosis patients, the majority of whom were neuroleptic-naïve, at baseline and after 3months of treatment, to determine whether change in pituitary volume was correlated with cumulative dose of atypical antipsychotic medication. There was no significant baseline difference in pituitary volume between subjects and controls, or between neuroleptic-naïve and neuroleptic-treated subjects. Over the follow-up period there was a negative correlation between percentage change in pituitary volume and cumulative 3-month dose of atypical antipsychotic (r=-0.37), i.e. volume increases were associated with lower doses and volume decreases with higher doses. Atypical antipsychotic medications may reduce pituitary gland volume in a dose-dependent manner suggesting that atypical antipsychotic medication may support affected individuals to cope with stress associated with emerging psychotic disorders.
Prescribed burning is highly uncommon in the Netherlands, where wildfire awareness is increasing but its risk management does not yet include fuel management strategies. A major exception is on two military bases, that need to burn their fields in winter and spring to prevent wildfires during summer shooting practice. Research on these very frequent burns has so far been limited to effects on biodiversity, yet site managers and policy makers have questions regarding the soil temperatures reached during these burns because of potential impact on soil properties and soil dwelling fauna. In March 2015, I therefore measured soil and litter temperatures under heath and grass vegetation during a prescribed burn on military terrain in the Netherlands. Soil and litter moisture were sampled pre- and post-fire, ash was collected, and fireline intensity was estimated from flame length. While standing vegetation was dry (0.13 g water/g biomass for grass and 0.6 g/g for heather), soil and litter were moist (0.21 cm3/cm3 and 1.6 g/g, respectively). Soil heating was therefore very limited, with maximum soil temperature at the soil-litter interface remaining being as low as 6.5 to 11.5°C, and litter temperatures reaching a maximum of 77.5°C at the top of the litter layer. As a result, any changes in physical properties like soil organic matter content and bulk density were not significant. These results are a first step towards a database of soil heating in relation to fuel load and fire intensity in this temperate country, which is not only valuable to increase understanding of the relationships between fire intensity and severity, but also instrumental in the policy debate regarding the sustainability of prescribed burns.
Full Text Available Silvio Caccia, Roberto William Invernizzi, Alessandro Nobili, Luca Pasina IRCCS-Istituto di Ricerche Farmacologiche Mario Negri, Milan, Italy Abstract: Cariprazine is a potential antipsychotic awaiting approval from the US Food and Drug Administration. It is a dopamine D2- and D3-receptor partial agonist, with higher affinity for D3 receptors, as opposed to the D2 antagonism of most older antipsychotic agents. Like most lipophilic antipsychotics, it undergoes extensive hepatic metabolism by cytochrome P450 (CYP, mainly the highly variable 3A4, with the formation of active metabolites. However, the parent compound – particularly its active didesmethyl derivative – is cleared very slowly, with elimination half-lives in schizophrenic patients ranging from 2–5 days for cariprazine to 2–3 weeks for didesmethyl-cariprazine. Exposure to the latter was several times that for cariprazine, although didesmethyl-cariprazine did not reach steady state within the 3 weeks of 12.5 mg/day dosing. Preliminary information on its therapeutic role comes from press releases and a few abstracts presented at scientific meetings. In short-term controlled trials, it was more effective than placebo in reducing positive and negative symptoms of schizophrenia, with an effective dose range of 1.5–12 mg/day. Although cariprazine was associated with a higher incidence of akathisia and extrapyramidal side effects than placebo, it did not cause weight gain, metabolic abnormalities, prolactin increase, or corrected QT prolongation. Similarly, cariprazine's efficacy and tolerability for the treatment of bipolar disorder (manic/mixed and depressive episodes was established in the dose range of 3–12 mg/day, although again no long-term data are available. Well-designed clinical trials, mainly direct "head-to-head" comparisons with other second-generation antipsychotic agents, are needed to define the therapeutic role and safety profile of cariprazine in schizophrenia and
Full Text Available Background/Aim. Immune system disorder, including inflammation, takes a significant place when considering still unclear etiology of schizophrenia. The aim of this study was to determine the blood levels of nonspecific inflammation markers in the first episode of schizophrenia and their relation to the therapy response. Methods. In this study we determined the blood levels of nonspecific inflammation markers: white blood cells count (WBC, C-reactive protein (CRP, erythrocytes sedimentation rate (ESR and the elements of differential white blood cell counts (or the leukocyte formula: granulocytes (Gra, lymphocytes (Lym and monocytes (Mon, in the first episode of schizofrenia, in 78 patients hospitalized at the Clinic for Psychiatric Disorders “Dr Laza Lazarević” in Belgrade. The levels were measured at admission to the clinic, as well as after 4 weeks of antipsychotic treatment. The Positive and negative syndrome scale for schizophrenia (PANSS was applied to measure the severity of psychopathology and response to the treatment. Results. During the first episode of schizophrenia, before initiation of antipsychotic treatment, the frequency of abnormal values was high (≥ 25% of the patients for the following non-specific inflammation markers: WBC, CRP, ESR and Gra, in the leukocyte formula, but dropped after 4 weeks of antipsychotic treatment at the level of high statistical significance for WBC and Gra (p < 0.001. The ESR remained unchanged in as many as 50% of the patients even after 4-week antipsychotic treatment, at the level of statistical significance in the non-responders compared to the responders (p = 0.045. Conclusion. The obtained results indicate that in the first episode of schizophrenia the blood levels of non-specific inflammation markers (WBS, CRP, ESR and Gra from the leukocyte formula were high in the subpopulation of patients with the tendency towards normalization of inflammation parameters after a 4-week antipsychotic

Chronic exposure to antipsychotic medications can persistently change brain dopamine systems. Most studies on the functional significance of these neural changes have focused on motor behavior and few have addressed how long-term antipsychotic treatment might influence dopamine-mediated reward function. We asked, therefore, whether a clinically relevant antipsychotic treatment regimen would alter the incentive motivational properties of a reward cue. We assessed the ability of a Pavlovian-conditioned stimulus to function as a conditioned reward, as well as to elicit approach behavior in rats treated with haloperidol, either continuously (achieved via subcutaneous osmotic minipump) or intermittently (achieved via daily subcutaneous injections). Continuous, but not intermittent, treatment enhanced the ability of amphetamine to potentiate the conditioned reinforcing effects of a cue associated with water. This effect was not related to differences in the ability to attribute predictive value to a conditioned stimulus (as measured by conditioned approach behavior), but was potentially linked to the development of behavioral supersensitivity to amphetamine and to augmented amphetamine-induced immediate early-gene expression (c-fos and Nur77) in dorsal striatopallidal and striatonigral cells. By enhancing the ability of reward cues to control behavior and by intensifying dopamine-mediated striatopallidal and striatonigral cell activity, standard (ie, continuous) antipsychotic treatment regimens might exacerbate drug-seeking and drug-taking behavior in schizophrenia. Achieving regular but transiently high antipsychotic levels in the brain (as modeled in the intermittent condition) might be a viable option to prevent these changes. This possibility should be explored in the clinic.
Full Text Available First- and second-generation antipsychotics (FGAs and SGAs, respectively, both inhibit cholesterol biosynthesis and impair the intracellular cholesterol trafficking, leading to lipid accumulation in the late endosome/lysosome compartment. In this study we examined if curcumin, a plant polyphenol that stimulates exosome release, can alleviate antipsychotic-induced intracellular lipid accumulation.HepG2 hepatocarcinoma cells were treated with antipsychotics or placebo and DiI-labelled LDL for 18 h and then exposed to curcumin for the last 2 h. Cells and media were collected separately and used for biochemical analyses, electron microscopy and immunocytochemistry. Exosomes were isolated from the incubation medium by ultracentrifugation.Curcumin treatment reduced the number of heterolysosomes and shifted their subcellular localization to the periphery, as revealed by electron microscopy, and stimulated the release of lysosomal β-hexosaminidase and exosome markers flotillin-2 and CD63 into the media. The presence of DiI in exosomes released by cells preloaded with DiI-LDL demonstrated the endolysosomal origin of the microvesicles. Furthermore, curcumin increased the secretion of cholesterol as well as LDL-derived DiI and [3H]-cholesterol, in association with a decrease of intracellular lipids. Thus, the disruption of lipid trafficking induced by FGAs or SGAs can be relieved by curcumin treatment. This polyphenol, however, did not mitigate the reduction of cholesterol esterification induced by antipsychotics.Curcumin stimulates exosome release to remove cholesterol (and presumably other lipids accumulated within the endolysosomal compartment, thereby normalizing intracellular lipid homeostasis. This action may help minimize the adverse metabolic effects of antipsychotic treatment, which should now be evaluated in clinical trials.
The first chapter of the following article discusses measures in terms of substitution treatment of a program of the Austrian Minister of the Interior. The relevance of psychosocial measures and aims of substitution treatment for opioid-dependent patients is illuminated. The abstinence as the only goal definition is modified and by the results of the study PREMOS a target differentiation at addiction work is illustrated. The second chapter addresses the misuse of prescribed drugs. Thereby police report data will be analyzed and the market situation of opioids will be outlined.

Full Text Available Physical exercise, aiming to improve range of movement, muscle strength and physical well being, lately substituted the immobilization previously prescribed in rheumatic diseases. International guidelines, recommendations of Scientific Societies, and structured reviews regard physical exercise as of pivotal importance in treating rheumatoid arthritis, ankylosing spondylitis, osteoarthritis, fibromyalgia syndrome, osteoporosis, and to be considered in connective tissue diseases. Therapeutic exercise should: aim to improve firstly local symptoms and then general health; respect the pain threshold; be a part of a treatment including pharmacological therapies and other rehabilitation techniques, be administered by skilled physiotherapist under the guide of a rheumatologist, be different according to different diseases, disease phases and patient expectations.

As wildfires increase in severity and intensity globally, the development of methods to assess their effects on soils is of increasing importance. We examined soil arthropod communities in the southern United States and estimated their abundance, species richness, and composition in areas recently impacted by prescribed burns. In addition, we placed thermal probes in soils and correlated soil temperatures to arthropod responses. Longer fire residence times resulted in greater soil heating which resulted in decreases in arthropod abundance and species richness and shifts in species composition. We believe that these results may be useful in developing tools to assess fire effects on soil systems.

Resident fatigue has become a point of emphasis in medical education and its effects on otolaryngology residents and their patients require further study. The purpose of our study was to evaluate the prevalence and nature of fatigue in otolaryngology residents, evaluate various quality of life measures, and investigate associations of increased fatigue with resident safety. Anonymous survey. Internet based. United States allopathic otolaryngology residents. None. The survey topics included demographics, residency structure, sleep habits and perceived stress. Responses were correlated with a concurrent Epworth Sleep Scale questionnaire to evaluate effects of fatigue on resident training and quality of life. 190 residents responded to the survey with 178 completing the Epworth Sleep Scale questionnaire. Results revealed a mean Epworth Sleep Scale score of 9.9±5.1 with a median of 10.0 indicating a significant number of otolaryngology residents are excessively sleepy. Statistically significant correlations between Epworth Sleep Scale and sex, region, hours of sleep, and work hours were found. Residents taking in-house call had significantly fewer hours of sleep compared to home call (p=0.01). Residents on "head and neck" (typically consisting of a large proportion of head and neck oncologic surgery) rotations tended to have higher Epworth Sleep Scale and had significantly fewer hours of sleep (p=.003) and greater work hours (potolaryngology residents are excessively sleepy. Our data suggest that the effects of fatigue play a role in resident well-being and resident safety. Copyright © 2016 Elsevier Inc. All rights reserved.
Simultaneous aerial- and ground-based emission sampling was conducted during prescribed burns at Eglin Air Force Base in November 2012 on a short grass/shrub field and a pine forest. Cumulative emission samples for volatile organic comounds, elemental carbon, organic carbon, chlorinated dioxins and furans, and PM2.5 and continuous samples for black carbon, particle size, and CO2 were taken. Aerial instruments were lofted using a 5 m diameter, helium-filled aerostat that was maneuvered with two remotely-controlled tethers mounted on all-terrain vehicles. A parallel set of instruments on the ground made simultaneous measurements, allowing for a comparison of ground level versus elevated measurements. Ground instruments were supplemented by additional measurements of polycyclic aromatic hydrocarbons and particle aerosol absorption and light scattering. Raw biomass was also gathered on site and tested in a laboratory combustion facility using the same array of instruments. This work compares emissions derived from aerial and ground sampling as well as field and laboratory results. This abstract will likely be the first ever prescribed burn study to compare laboratory and field emission results with results from aerial and and ground sampling. As such it will inform sampling methods for future events and determine the ability of laboratory simulations to mimic events inthe field.
This article presents the challenges regarding the development of a collaborative practice agreement in order to undertake nurse prescribing in an emergency department in a large teaching hospital. Nurse prescribing has been introduced quite recently in Ireland. Although there is a plethora of knowledge regarding the topic, there are many personal and professional challenges in relation to this emerging role. The nurse prescribing initiative in Ireland is continually developing and many nurses now have the authority to prescribe from almost the same range of medicines as doctors. Prescribing has the potential to improve job satisfaction, autonomy and ultimately improves patient outcomes. However, nurses need to be cognisant of the impact it can have on the dynamics of the healthcare team. An analysis of some complexities of nurse prescribing is given, in conjunction with reflective thoughts on a clinical incident in the area of morphine prescribing.

This paper is a report of a study exploring the views of nurses and team members on the implementation of nurse prescribing in diabetes services. Nurse prescribing is adopted as a means of improving service efficiency, particularly where demand outstretches resources. Although factors that support nurse prescribing have been identified, it is not known how these function within specific contexts. This is important as its uptake and use varies according to mode of prescribing and area of practice. A case study was undertaken in nine practice settings across England where nurses prescribed medicines for patients with diabetes. Thematic analysis was conducted on qualitative data from 31 semi-structured interviews undertaken between 2007 and 2008. Participants were qualified nurse prescribers, administrative staff, physicians and non-nurse prescribers. Nurses prescribed more often following the expansion of nurse independent prescribing rights in 2006. Initial implementation problems had been resolved and few current problems were reported. As nurses' roles were well-established, no major alterations to service provision were required to implement nurse prescribing. Access to formal and informal resources for support and training were available. Participants were accepting and supportive of this initiative to improve the efficiency of diabetes services. The main factors that promoted implementation of nurse prescribing in this setting were the ability to prescribe independently, acceptance of the prescribing role, good working relationships between doctors and nurses, and sound organizational and interpersonal support. The history of established nursing roles in diabetes care, and increasing service demand, meant that these diabetes services were primed to assimilate nurse prescribing.

To describe facilitators and barriers in relation to the growth of nurse prescribing competence from the perspective of the nurses studying in a prescribing programme. The number of nurses enrolled in a nurse prescribing programme is rapidly increasing in Finland. However, few studies on nurse prescribing education are available and therefore research is needed, particularly from the point of view of nurses studying in the programme. The descriptive, qualitative study used the text of student online learning diaries as data during a 14-month prescribing programme. The sample consisted of 31 nurses, public health nurses or midwives enrolled in a prescribing programme at a university of applied sciences. The data were analysed using the inductive analysis method. The growth of nurses' prescribing competence was facilitated by learning clinical examination of the patient, networking with peers, receiving support from the workplace and supervisors, doctors' positive attitude towards nurse prescribing and being able to apply competencies directly to nursing practice. The barriers to the growth of nurses' prescribing competence were unclear job description, incomplete care plans and concerns about how consultation with doctors will be organised and realised. The results show that, for the purpose of developing the new role and position of nurse prescribers, educators and nursing managers must invest more in staff awareness of nurse prescribing education and also offer more support to nurse prescribers in their workplaces. The results of this study can be used especially in countries where nurse prescribing education is only in the process of being planned or has just been started. Heads of nursing and educators in prescribing education will benefit from the results when creating expanded job descriptions for nurses and supporting networking between students during the period of training. © 2016 John Wiley & Sons Ltd.

Little is known about the knowledge and skills internal medicine residents need to interact appropriately with pharmaceutical industry representatives. The authors conducted a needs assessment of current knowledge and preferences for potential components of a new educational initiative among residents. In 2001, a two-page questionnaire using a five-point ordinal scale was mailed to all internal medicine residents and faculty at one institution. Analysis included use of Wilcoxon two-sample test. Response rates were 97% (85/88) for residents and 79% (86/109) for faculty. Residents and faculty's knowledge about formal position statements or literature on the impact of marketing strategies on prescribing patterns, drug marketing costs, or how pharmaceutical representatives are trained to interact with physicians was very limited. Most responders felt residents should learn to critically interpret promotional materials, recognize potential for conflict of interest, and consider how patients perceive the physician-pharmaceutical industry relationship. More faculty than residents valued including position statements (66% versus 39%, p marketing on prescribing patterns (70% versus 41%, p education. Only one-half or fewer favored small-group discussions, lecture series, critical-reading skills seminars, or panel discussions. Internal medicine residents and faculty reported low levels of knowledge about physician-pharmaceutical industry relationships. Some consensus about educational components existed, but optimal educational formats remain uncertain. A six-hour curriculum to address this complex, emotionally charged topic was developed, implemented, and evaluated.

Objective was to evaluate the use of antibiotics prescribed in hospital outpatient and emergency clinics in King Hussein Medical Centre (KHMC) using WHO prescribing indicators in an attempt to rationalize the use of antibiotics in the Royal Medical Services. We retrospectively surveyed a sample of 187,822 antibiotic prescriptions obtained from 5 outpatient pharmacies in KHMC written over the period of 3 consecutive months May 2007 to July 2007. The percentage of encounters of an antibiotic prescribed was calculated using the methodology recommended by the WHO. An additional indicator, the percentage share of different antibiotics was also included to identify the frequency prescribed from those antibiotics. The average percentage of prescriptions involving antibiotics was 35.6% out of 187,822 prescriptions surveyed. From these, 65,500 antibiotic prescriptions were observed. Penicillins most frequently amoxcillins and Quinolones most frequently ciprofloxacinllin and norfloxacillin were the most commonly prescribed antibiotics with an average percentage of 31.8% and 27.5%. The average prescribing rate for the other antibiotic categories was as follows: macrolides 5.2%, cephalosporins 16% and amoxcillins/clavulanate 5.4%. The high percentage of prescriptions involving antibiotics observed in KHMC pharmacies requires rational use of antibiotics and judicious prescribing by Military prescribers. An insight into factors influencing antibiotic prescribing patterns and adherence to antibiotic prescribing guidelines by the Military prescribers is warranted. (author)

Attention deficits have been frequently reported in schizophrenia. It has been suggested that treatment with second-generation antipsychotics can ameliorate these deficits. In this study, the influence of 6 months treatment with quetiapine, a compound with less affinity for dopamine D2 receptors than for serotonergic 5-HT2A receptors, on electrophysiological parameters of attention was investigated in a group of antipsychotic-naïve, first-episode schizophrenia patients compared with a group of age- and gender-matched healthy controls. A total of 34 first-episode, antipsychotic-naïve patients with schizophrenia and an equal number of healthy controls were tested in a selective attention and a typical mismatch negativity (MMN) paradigm at baseline and after 6 months. The patients were treated with quetiapine according to their clinical needs during the period between baseline and follow-up, whereas controls received no treatment. Patients showed lower MMN and P200 amplitude than healthy controls in the selective attention paradigm at baseline, while this was not the case for MMN of the typical MMN paradigm. Interestingly, after 6 months treatment, this MMN deficit was only ameliorated in patients treated with above median dosages of quetiapine. Patients had lower P3B amplitude, yet showed similar levels of processing negativity and N100 amplitude compared with healthy controls, both at baseline and follow-up. The results indicate that deficits in MMN, P200 and P3B amplitude are present at early stages of schizophrenia, although depending on the paradigm used. Furthermore, the results indicate that 6 months quetiapine treatment ameliorates MMN but not P3B deficits, and only in those subjects on higher dosages.

However, at the same time, its comparatively high cost gave rise to concerns about the cost-effectiveness of PER as compared with its precursor, risperidone. This paper reviews the existing knowledge of the pharmacology, kinetics, efficacy, tolerability, and fields of application of PER, and compares PER with risperidone in order to determine whether it has a place in antipsychotic therapy. An independent assessment of all relevant publications on PER published until July 2010 was undertaken. PER has a unique pharmacological profile, including single dosing, predominantly renal excretion, low drug–drug interaction risk, and differs from risperidone in terms of mode of action and pharmacokinetics. High-level evidence suggests that PER is efficacious and safe in schizophrenia, schizoaffective disorder, and acute manic episodes. There is a striking lack of published head-to-head comparisons between PER and risperidone, irrespective of indication. Low-level evidence shows a lower risk for hyperprolactinemia and higher patient satisfaction with PER than with risperidone. PER adds to the still limited arsenal of second-generation antipsychotics. In the absence of direct comparisons with risperidone, it remains difficult to come to a final verdict on the potential additional therapeutic benefits of PER which would justify its substantially
Full Text Available Abstract Background Use of the atypical antipsychotic sertindole was suspended for four years due to safety concerns. During the suspension, the regulatory authorities required further studies, including this one, to be conducted. The purpose of this study was to determine if a subset of patients with psychotic illness exists which particularly benefits from sertindole treatment after failure of other antipsychotic drugs, including atypical antipsychotics. Methods This was a retrospective single-arm observational crossover study of 344 patients, who served as their own controls. Patients mainly from the Sertindole Safety Study who had shown good response to sertindole, and who had followed up to four alternating six month periods of treatment with sertindole and other antipsychotics, were included. (In Period 1 patients took non-sertindole treatment, in Period 2, sertindole was taken, in Period 3, patients reverted to non-sertindole treatment, and in Period 4, sertindole was taken again. Patient records for each period of treatment were assessed for objective data: number and duration of hospitalizations due to worsening of psychotic symptoms; the amount of self-harming behaviour; indicators of social status. Retrospective evaluation of changes in clinical symptoms from the patients' records was also conducted. Dates and reasons for stopping and/or switching medication were also recorded. Results There was improvement in all objective measured parameters during the periods of sertindole treatment. In particular, the average number of hospitalizations per year due to worsening of psychotic symptoms was reduced in the following way in the group studied over four treatment periods: Period 1 (non-sertindole treatment 3.4; Period 2 (sertindole treatment 1.0; Period 3 (non-sertindole treatment 2.0; Period 4 (sertindole treatment 1.8. The duration of hospitalizations also decreased significantly during the periods of sertindole treatment. Results

Antipsychotic response after the initiation of neuroleptic treatment shows wide variation in schizophrenic patient populations. In this overview, the authors suggest that the variance in antipsychotic drug response within schizophrenia can be reduced by resolving the schizophrenias into several discrete "endophenotypes," each with different etiologic underpinnings. Studies relating differences in the relative speed or completeness of antipsychotic response to differences in distribution of 2 biological markers with possible etiologic significance are reviewed. Such studies had assessed recently hospitalized, neuroleptic-free patients undergoing exacerbation of nonaffective psychotic disorders. Prior to initiation of neuroleptic, the cohort of patients had been assessed for the quantity of the dopamine metabolite homovanillic acid in plasma (pHVA) and had undergone the first of 2 magnetic resonance imaging (MRI) studies for analyses of ventricle volumes. A second MRI was subsequently performed during a period of (partial) remission to determine within-patient stability of ventricular volumes. These selected studies assessed the distribution of pHVA and distribution of rates of ventricular change, with non-normal distributions resolved by K-means clustering. The speed and completeness of neuroleptic-induced antipsychotic response were related to 3 clusters of patients delineated by modal distributions of pHVA and of apparent rates of ventricular change. At least 3 unique "endophenotypes" of the "group of the schizophrenias" can be defined with respect to speed and completeness of antipsychotic response. Each endophenotype appears to show at least one unique biological feature that differentiates it from a normal comparison group. A rapidly responsive psychosis was associated with excessive production of dopamine, as identifiable by elevation of pHVA and a "good-prognosis" course. A delayed-response psychosis had low-to-normal pHVA, clinically demonstrated persistent

Interpretation & conclusions: Treatment with antipsychotics and psychoeducation can favourably influence the course of schizophrenia and reduce disability in a substantial proportion of patients. Structured psychosocial interventions may be indicated in the significant minority who show suboptimal outcome with this strategy.

Full Text Available Abstract Background Atypical antipsychotics provide better control of the negative and affective symptoms of schizophrenia when compared with conventional neuroleptics; nevertheless, their heightened ability to improve cognitive dysfunction remains a matter of debate. This study aimed to examine the changes in cognition associated with long-term antipsychotic treatment and to evaluate the effect of the type of antipsychotic (conventional versus novel antipsychotic drugs on cognitive performance over time. Methods In this naturalistic study, we used a comprehensive neuropsychological battery of tests to assess a sample of schizophrenia patients taking either conventional (n = 13 or novel antipsychotics (n = 26 at baseline and at two years after. Results Continuous antipsychotic treatment regardless of class was associated with improvement on verbal fluency, executive functions, and visual and verbal memory. Patients taking atypical antipsychotics did not show greater cognitive enhancement over two years than patients taking conventional antipsychotics. Conclusions Although long-term antipsychotic treatment slightly improved cognitive function, the switch from conventional to atypical antipsychotic treatment should not be based exclusively on the presence of these cognitive deficits.

To establish the mortality risk and adverse events associated with the use of atypical antipsychotic medications in people with Parkinson disease psychosis (PDP) in a clinically defined trial cohort. Post hoc analysis of data from a multicenter, open-label extension study of pimavanserin comparing people taking and not taking current antipsychotics. Primary and secondary care medical centers in the United States, Canada, Europe, and India. A total of 459 people with PDP enrolled in the extension study. Participants were between ages 30 and 80 years, and had an established diagnosis of idiopathic Parkinson disease and moderate to severe psychosis. Participants were categorized into 2 groups: those receiving concomitant antipsychotic medications ("concurrent APD") and those who did not take antipsychotic medications at any time during the study ("no APD"). Participants were receiving 40 mg pimavanserin daily in addition to concurrent antipsychotics and Parkinson disease medications. Safety assessments at 2 weeks; 1, 3, 6, 9, and 12 months; and every 6 months thereafter, including evaluation of adverse events (AEs), vital signs, weight, physical examinations, 12-lead electrocardiograms, clinical laboratory tests (serum chemistry, hematology, and urinalysis), and the Unified Parkinson's Disease Rating Scale Parts II and III (UPDRS-II+III, activities of daily living and motor impairment, respectively).
