    Kurimoto, Fuki; Hori, Satoko; Satoh, Hiroki; Miki, Akiko; Sawada, Yasufumi


    For drug fostering and evolution, it is important to collect information directly from patients on the efficacy and safety of drugs as well as patient needs. At present, however, information gathered by healthcare professionals, pharmaceutical companies, or governments is not sufficient. There is concern that patients may fail to recognize the importance of providing information voluntarily. The present study was conducted to provide drug information to patients/consumers, to enlighten them on the importance of providing drug information by themselves, and to develop an Internet website, called "Minkusu," for collecting drug information from patients. This website is based on a registration system (free of charge). It is designed to provide information on proper drug use, and to collect opinions about drugs. As of May 31, 2012, a total of 1149 people had been registered. The male/female ratio of registered members was approximately 1:1, and patients/consumers accounted for 23%. According to the results of a questionnaire survey, several patient/consumer members appreciated the usefulness of the information service, and they took an opportunity to know of the concepts of drug development and evolution (Ikuyaku, in Japanese) through the information services provided by this site. In conclusion, the developed information system would contribute to the proper use of drugs by patients/consumers and to the promotion of drug development and evolution.

    Puentes, John; Batrancourt, Bénédicte; Atif, Jamal; Angelini, Elsa; Lecornu, Laurent; Zemirline, Abdelhamid; Bloch, Isabelle; Coatrieux, Gouenou; Roux, Christian


    Current electronic patient record (EPR) implementations do not incorporate medical images, nor structural information extracted from them, despite images increasing role for diagnosis. This paper presents an integration framework into EPRs of anatomical and pathological knowledge extracted from segmented magnetic resonance imaging (MRI), applying a graph of representation for anatomical and functional information for individual patients. Focusing on cerebral tumors examination and patient follow-up, multimedia EPRs were created and evaluated through a 3D navigation application, developed with open-source libraries and standards. Results suggest that the enhanced clinical information scheme could lead to original changes in the way medical experts utilize image-based information.

  3. Informing cancer patient based on his type of personality: the suspicious (paranoid) patient. (United States)

    Kallergis, G


    Imparting bad news had always been an unpleasant task for the physician, as shown from ancient years to our days. In the healthcare sector and as far as the cancer patient is concerned, the imparting of bad news is performed by the patient's doctor within a therapeutic relationship of course. The fundamental question is how a therapist could tailor the information to any patient and if "Is it possible to determine who should be told what, when and how ?". The aim of this paper was to describe the suspicious character or type of personality thoroughly so that any physician can make a diagnosis and tailor the information strategy to the patient's needs. As method of research was used the qualitative method through groups with doctors and nurses, while research within groups lasted for 5 years. The degree of informing of the suspicious personality in the range "minimal - small - medium - large - very large" is : the degree of denial varies between large and very large. The degree of informing varies between medium and small and sometimes minimal. Informing the Family: The hardest family to deal with. Pay attention to litigious mania. Avoid confrontation or be drawn into agreeing with the family views.

    Full Text Available BackgroundWarfarin is a high-risk medication where patient information may be critical to help ensure safe and effective treatment. Considering the time constraints of healthcare providers, the internet can be an important supplementary information resource for patients prescribed warfarin. The usefulness of internet-based patient information is often limited by challenges associated with finding valid and reliable health information. Given patients’ increasing access of the internet for information, this study investigated the quality, suitability and readability of patient information about warfarin presented on the internet.MethodPreviously validated tools were used to evaluate the quality, suitability and readability of patient information about warfarin on selected websites.ResultsThe initial search yielded 200 websites, of which 11 fit selection criteria, comprising seven non-commercial and four commercial websites. Regarding quality, most of the non-commercial sites (six out of seven scored at least an ‘adequate’ score. With regard to suitability, 6 of the 11 websites (including two of the four commercial sites attained an ‘adequate’ score. It was determined that information on 7 of the 11 sites (including two commercial sites was written at reading grade levels beyond that considered representative of the adult patient population with poor literacy skills (e.g. school grade 8 or less.ConclusionDespite the overall ‘adequate’ quality and suitability of the internet derived patient information about warfarin, the actual usability of such websites may be limited due to their poor readability grades, particularly in patients with low literacy skills.

  5. Are internet sites providing evidence-based information for patients suffering with Trigeminal Neuralgia? (United States)

    Demetriades, Andreas K; Alg, Varinder Singh; Hardwidge, Carl


    Trigeminal neuralgia has a variety of treatments with variable efficacy. Sufferers present to a spectrum of disciplines. While traditional delivery of medical information has been by oral/printed communication, up to 50-80% patients access the internet for information. Confusion, therefore, may arise when seeking treatment for trigeminal neuralgia. We evaluated the quality of information on the internet for trigeminal neuralgia using the DISCERN© instrument. Only 54% websites had clear objectives; 42% delivered on these. A total of 71% provided relevant information on trigeminal neuralgia, 54% being biased/unbalanced; 71% not providing clear sources of information. No website detailed the side-effect profile of treatments; 79% did not inform patients of the consequences/natural history if no treatment was undertaken; it was unclear if patients could anticipate symptoms settling or when treatment would be indicated. Internet information on trigeminal neuralgia is of variable quality; 83% of sites assessed were of low-to-moderate quality, 29% having 'serious shortcomings.' Only two sites scored highly, only one being in the top 10 search results. Websites on trigeminal neuralgia need to appreciate areas highlighted in the DISCERN© instrument, in order to provide balanced, reliable, evidence-based information. To advise patients who may be misguided from such sources, neurosurgeons should be aware of the quality of information on the internet.

  6. An information entropy model on clinical assessment of patients based on the holographic field of meridian (United States)

    Wu, Jingjing; Wu, Xinming; Li, Pengfei; Li, Nan; Mao, Xiaomei; Chai, Lihe


    Meridian system is not only the basis of traditional Chinese medicine (TCM) method (e.g. acupuncture, massage), but also the core of TCM's basic theory. This paper has introduced a new informational perspective to understand the reality and the holographic field of meridian. Based on maximum information entropy principle (MIEP), a dynamic equation for the holographic field has been deduced, which reflects the evolutionary characteristics of meridian. By using self-organizing artificial neural network as algorithm, the evolutionary dynamic equation of the holographic field can be resolved to assess properties of meridians and clinically diagnose the health characteristics of patients. Finally, through some cases from clinical patients (e.g. a 30-year-old male patient, an apoplectic patient, an epilepsy patient), we use this model to assess the evolutionary properties of meridians. It is proved that this model not only has significant implications in revealing the essence of meridian in TCM, but also may play a guiding role in clinical assessment of patients based on the holographic field of meridians.

  7. Wavelet-Based ECG Steganography for Protecting Patient Confidential Information in Point-of-Care Systems. (United States)

    Ibaida, Ayman; Khalil, Ibrahim


    With the growing number of aging population and a significant portion of that suffering from cardiac diseases, it is conceivable that remote ECG patient monitoring systems are expected to be widely used as point-of-care (PoC) applications in hospitals around the world. Therefore, huge amount of ECG signal collected by body sensor networks from remote patients at homes will be transmitted along with other physiological readings such as blood pressure, temperature, glucose level, etc., and diagnosed by those remote patient monitoring systems. It is utterly important that patient confidentiality is protected while data are being transmitted over the public network as well as when they are stored in hospital servers used by remote monitoring systems. In this paper, a wavelet-based steganography technique has been introduced which combines encryption and scrambling technique to protect patient confidential data. The proposed method allows ECG signal to hide its corresponding patient confidential data and other physiological information thus guaranteeing the integration between ECG and the rest. To evaluate the effectiveness of the proposed technique on the ECG signal, two distortion measurement metrics have been used: the percentage residual difference and the wavelet weighted PRD. It is found that the proposed technique provides high-security protection for patients data with low (less than 1%) distortion and ECG data remain diagnosable after watermarking (i.e., hiding patient confidential data) and as well as after watermarks (i.e., hidden data) are removed from the watermarked data.

  8. Scoring performance on computer-based patient simulations: beyond value of information. (United States)

    Downs, S M; Marasigan, F; Abraham, V; Wildemuth, B; Friedman, C P


    As computer based clinical case simulations become increasingly popular for training and evaluating clinicians, approaches are needed to evaluate a trainee's or examinee's solution of the simulated cases. In 1997 we developed a decision analytic approach to scoring performance on computerized patient case simulations, using expected value of information (VOI) to generate a score each time the user requested clinical information from the simulation. Although this measure has many desirable characteristics, we found that the VOI was zero for the majority of information requests. We enhanced our original algorithm to measure potential decrements in expected utility that could result from using results of information requests that have zero VOI. Like the original algorithm, the new approach uses decision models, represented as influence diagrams, to represent the diagnostic problem. The process of solving computer based patient simulations involves repeated cycles of requesting and receiving these data from the simulations. Each time the user requests clinical data from the simulation, the influence diagram is evaluated to determine the expected VOI of the requested clinical datum. The VOI is non-zero only it the requested datum has the potential to change the leading diagnosis. The VOI is zero when the data item requested does not map to any node in the influence diagram or when the item maps to a node but does not change the leading diagnosis regardless of it's value. Our new algorithm generates a score for each of these situations by modeling what would happen to the expected utility of the model if the user changes the leading diagnosis based on the results. The resulting algorithm produces a non-zero score for all information requests. The score is the VOI when the VOI is non-zero It is a negative number when the VOI is zero.

  9. Improving access to computer-based library and drug information services in patient-care areas. (United States)

    Tobia, R C; Bierschenk, N F; Knodel, L C; Bowden, V M


    A project to increase access to drug and biomedical information through electronic linkage of drug information and library services to three patient-care areas is described. In February 1987, microcomputer work stations were installed in the Bexar County Hospital District's hospital emergency department, medical residents' office, and ambulatory-care clinic, as well as in The University of Texas Health Science Center's library reference area and drug information service office. Drug information was available on compact disk through the Micromedex Computerized Clinical Information System (CCIS) database, which includes DRUGDEX, POISINDEX, EMERGINDEX, and IDENTIDEX. Each work station was also connected to the library's computer via modem, allowing access to the Library Information System, books, journals, audiovisual materials, miniMEDLINE, and an electronic mail system. During the six-month project, the system was used 5487 times by 702 people. The system was successful in providing drug and other information in clinical settings and in introducing clinical staff members to new information technology. To increase access to the system after the project ended, the CD-ROM version was discontinued, and the distributed tape version of CCIS for VAX computers was added to the library's online information system, making drug information more available throughout the campus and teaching hospitals. In 1988-89 an average of 200 people accessed the tape version of CCIS each month. Although it is difficult to replace the convenience of an onsite library, at least some drug and biomedical information needs in the clinical setting can be met through computer networking.

  11. DELirium Prediction Based on Hospital Information (Delphi) in General Surgery Patients. (United States)

    Kim, Min Young; Park, Ui Jun; Kim, Hyoung Tae; Cho, Won Hyun


    To develop a simple and accurate delirium prediction score that would allow identification of individuals with a high probability of postoperative delirium on the basis of preoperative and immediate postoperative data.Postoperative delirium, although transient, is associated with adverse outcomes after surgery. However, there has been no appropriate tool to predict postoperative delirium.This was a prospective observational single-center study, which consisted of the development of the DELirium Prediction based on Hospital Information (Delphi) score (n = 561) and its validation (n = 533). We collected potential risk factors for postoperative delirium, which were identified by conducting a comprehensive review of the literatures.Age, low physical activity, hearing impairment, heavy alcoholism, history of prior delirium, intensive care unit (ICU) admission, emergency surgery, open surgery, and increased preoperative C-reactive protein were identified as independent predictors of postoperative delirium. The Delphi score was generated using logistic regression coefficients. The maximum Delphi score was 15 and the optimal cut-off point identified with the Youden index was 6.5. Generated area under the (AUC) of the receiver operating characteristic (ROC) curve was 0.911 (95% CI: 0.88-0.94). In the validation study, the calculated AUC of the ROC curve based on the Delphi score was 0.938 (95% Cl: 0.91-0.97). We divided the validation cohort into the low-risk group (Delphi score 0-6) and high-risk group (7-15). Sensitivity of Delphi score was 80.8% and specificity 92.5%.Our proposed Delphi score could help health-care provider to predict the development of delirium and make possible targeted intervention to prevent delirium in high-risk surgery patients.

  12. Discrete wavelet transform and singular value decomposition based ECG steganography for secured patient information transmission. (United States)

    Edward Jero, S; Ramu, Palaniappan; Ramakrishnan, S


    ECG Steganography provides secured transmission of secret information such as patient personal information through ECG signals. This paper proposes an approach that uses discrete wavelet transform to decompose signals and singular value decomposition (SVD) to embed the secret information into the decomposed ECG signal. The novelty of the proposed method is to embed the watermark using SVD into the two dimensional (2D) ECG image. The embedding of secret information in a selected sub band of the decomposed ECG is achieved by replacing the singular values of the decomposed cover image by the singular values of the secret data. The performance assessment of the proposed approach allows understanding the suitable sub-band to hide secret data and the signal degradation that will affect diagnosability. Performance is measured using metrics like Kullback-Leibler divergence (KL), percentage residual difference (PRD), peak signal to noise ratio (PSNR) and bit error rate (BER). A dynamic location selection approach for embedding the singular values is also discussed. The proposed approach is demonstrated on a MIT-BIH database and the observations validate that HH is the ideal sub-band to hide data. It is also observed that the signal degradation (less than 0.6%) is very less in the proposed approach even with the secret data being as large as the sub band size. So, it does not affect the diagnosability and is reliable to transmit patient information.

  13. Conceptual model of health information ethics as a basis for computer-based instructions for electronic patient record systems. (United States)

    Okada, Mihoko; Yamamoto, Kazuko; Watanabe, Kayo


    A computer-based learning system called Electronic Patient Record (EPR) Laboratory has been developed for students to acquire knowledge and practical skills of EPR systems. The Laboratory is basically for self-learning. Among the subjects dealt with in the system is health information ethics. We consider this to be of the utmost importance for personnel involved in patient information handling. The variety of material on the subject has led to a problem in dealing with it in a methodical manner. In this paper, we present a conceptual model of health information ethics developed using UML to represent the semantics and the knowledge of the domain. Based on the model, we could represent the scope of health information ethics, give structure to the learning materials, and build a control mechanism for a test, fail and review cycle. We consider that the approach is applicable to other domains.

  14. A System Design for Studying Geriatric Patients with Dementia and Hypertension Based on Daily Living Information (United States)

    Xu, Weifeng; Betz, Willian R.; Frezza, Stephen T.; Liu, Yunkai


    Geriatric patients with dementia and hypertension (DAH) suffer both physically and financially. The needs of these patients mainly include improving the quality of daily living and reducing the cost of long-term care. Traditional treatment approaches are strained to meet these needs. The goal of the paper is to design an innovative system to provide cost-effective quality treatments for geriatric patients with DAH by collecting and analyzing the multi-dimensional personal information, such as observations in daily living (ODL) from a non-clinical environment. The proposed ODLs in paper include activities, cleanliness, blood pressure, medication compliance and mood changes. To complete the system design, an incremental user-centered strategy is exploited to assemble needs of patients, caregivers, and clinicians. A service-oriented architecture (SOA) is employed to make full use of existing devices, software systems, and platforms. This health-related knowledge can be interpreted and utilized to help patients with DAH remain in their homes safely and improve their life quality while reducing medical expenditures.

  15. A case based reflection on communicating end of life information in non-English speaking patients. (United States)

    Hume, Carl; Malpas, Phillipa


    Mr X was a 56year old Chinese man (non-English speaking), who presented to the emergency department with a range of non-specific symptoms. On full workup, he was diagnosed with an advanced cancer of the pancreas. It was an aggressive, highly treatment resistant cancer, with an alarmingly poor prognosis. Before the diagnosis had been made, the family had informed our team that we were not to discuss medical issues with Mr X directly, and that upon arriving on a diagnosis we were to come to them first and they would subsequently inform him. They reported that Mr X was in support of this arrangement. Eventually we told the family about Mr X's diagnosis, and they asserted their collective will to keep this information from him, reaffirming that all medical discussion go through them. However, the doctor in charge explained the diagnosis to Mr X using an interpreter while his family were away from his bed. In this discussion, I consider this case from the perspective of respecting patients' and families' preferences around medical treatment and care.

    Directory of Open Access Journals (Sweden)

    Giani Guido


    Full Text Available Abstract Background Evidence-based patient information (EBPI has been recognised as important tool for informed choice in particular in the matter of preventive options. An objective, on the best scientific evidence-based consumer information about subthreshold elevated blood glucose levels (impaired fasting glucose and impaired glucose tolerance and primary prevention of diabetes, is not available yet. Thus we developed a web-based EBPI and aim to evaluate its effects on informed decision making in people 50 years or older. Methods/Design We conduct a web-based randomised-controlled trial to evaluate the effect of information about elevated blood glucose levels and diabetes primary prevention on five specific outcomes: (i knowledge of elevated blood glucose level-related issues (primary outcome; (ii attitudes to a metabolic testing; (iii intention to undergo a metabolic testing; (iv decision conflict; (v satisfaction with the information. The intervention group receives a specially developed EBPI about subthreshold elevated blood glucose levels and diabetes primary prevention, the control group information about this topic, available in the internet. The study population consists of people between 50 and 69 years of age without known diabetes. Participants will be recruited via the internet page of the cooperating health insurance company, Techniker Krankenkasse (TK, and the internet page of the German Diabetes Centre. Outcomes will be measured through online questionnaires. We expect better informed participants in the intervention group. Discussion The design of this study may be a prototype for other web-based prevention information and their evaluation. Trial registration Current Controlled Trial: ISRCTN22060616.

  17. Development and Implementation of Team-Based Panel Management Tools: Filling the Gap between Patient and Population Information Systems. (United States)

    Watts, Brook; Lawrence, Renée H; Drawz, Paul; Carter, Cameron; Shumaker, Amy Hirsch; Kern, Elizabeth F


    Effective team-based models of care, such as the Patient-Centered Medical Home, require electronic tools to support proactive population management strategies that emphasize care coordination and quality improvement. Despite the spread of electronic health records (EHRs) and vendors marketing population health tools, clinical practices still may lack the ability to have: (1) local control over types of data collected/reports generated, (2) timely data (eg, up-to-date data, not several months old), and accordingly (3) the ability to efficiently monitor and improve patient outcomes. This article describes a quality improvement project at the hospital system level to develop and implement a flexible panel management (PM) tool to improve care of subpopulations of patients (eg, panels of patients with diabetes) by clinical teams. An in-depth case analysis approach is used to explore barriers and facilitators in building a PM registry tool for team-based management needs using standard data elements (eg, laboratory values, pharmacy records) found in EHRs. Also described are factors that may contribute to sustainability; to date the tool has been adapted to 6 disease-focused subpopulations encompassing more than 200,000 patients. Two key lessons emerged from this initiative: (1) though challenging, team-based clinical end users and information technology needed to work together consistently to refine the product, and (2) locally developed population management tools can provide efficient data tracking for frontline clinical teams and leadership. The preliminary work identified critical gaps that were successfully addressed by building local PM registry tools from EHR-derived data and offers lessons learned for others engaged in similar work.

  18. Protocol for a Randomized Controlled Trial of Proactive Web-Based Versus Telephone-Based Information and Support: Can Electronic Platforms Deliver Effective Care for Lung Cancer Patients? (United States)

    Boyes, Allison W; O'Brien, Lorna; Baker, Amanda L; Henskens, Frans A; Clinton-McHarg, Tara; Bellamy, Douglas; Colburn, Glenda; Rose, Shiho; Cox, Martine E; Fradgley, Elizabeth A; Baird, Hannah; Barker, Daniel


    Background Community-based services such as telephone support lines can provide valuable informational, emotional, and practical support for cancer patients via telephone- or Web-based (live chat or email) platforms. However, very little rigorous research has examined the efficacy of such services in improving patient outcomes. Objective This study will determine whether: proactive telephone or Web-delivered support produces outcomes superior to printed information; and Web-delivered support produces outcomes comparable to telephone support. Methods A consecutive sample of 501 lung cancer outpatients will be recruited from 50 Australian health services to participate in a patient-randomized controlled trial (RCT). Eligible individuals must: be 18 years or older; have received a lung cancer diagnosis (including mesothelioma) within the previous 4 months; have an approximate life expectancy of at least 6 months; and have Internet access. Participants will be randomly allocated to receive: (1) an information booklet, (2) proactive telephone support, or (3) proactive Web support, chat, and/or email. The primary patient outcomes will be measured by the General Health Questionnaire (GHQ-12) and Health Education and Impact Questionnaire (heiQ) at 3 and 6 months post recruitment. The acceptability of proactive recruitment strategies will also be assessed. Results It is hypothesized that participants receiving telephone or Web support will report reduced distress (GHQ-12 scores that are 0.3 standard deviations (SD) lower) and greater self-efficacy (heiQ scores that are 0.3 SDs higher) than participants receiving booklets. Individuals receiving Web support will report heiQ scores within 0.29 SDs of individuals receiving telephone support. Conclusions If proven effective, electronic approaches such as live-chat and email have the potential to increase the accessibility and continuity of supportive care delivered by community-based services. This evidence may also inform the

  20. How can clinical biobanks and patient information be adapted for research – Establishing a hospital based data warehouse solution

    Directory of Open Access Journals (Sweden)

    Wenche Reed


    Full Text Available The use of human biological material and related clinical information is central in basic research, translational research and clinical research. Extracting this information from hospital information systems is time-consuming and labor intensive. Establishing a data warehouse is a possible solution to extract the information in an efficient and secure way. An information model for a data warehouse has been developed at the Oslo University Hospital in collaboration with Akershus University Hospital. Being hospitals, the overall information model is patientcentered. The model also allows for appropriate data exchange between different organizations. The model is described with a focus on some of the major conditions for success with respect to the legal and organizational framework of Norwegian hospitals. A web-based information and tracking system for clinical biobanks is an important element of the model, and one of the aims of the national project Biobank Norway


    Taylor, Mark J


    The disclosure of confidential patient data without an individual's explicit consent should be for purposes that persons have reason to both expect and accept. We do not currently have the required level of clarity or consistency in understanding regarding the disclosure of confidential patient information for public health purposes to support effective public dialogue. The Health Service (Control of Patient Information) Regulations 2002 establish a legal basis in England and Wales for data to be disclosed for public health purposes without patient consent. Under the Regulations, there is more than one potential route towards lawful processing: Data may be processed for public health purposes under both Regulations 3 and 5. The alternatives have different safeguards and conditions attached, and their respective applicability to processing for purposes of public health improvement is currently unclear and subject to review. Beyond the need for clarity regarding the safeguards applicable to processing for particular public health purposes, there are reasons to prefer recognition that Regulation 5 is the most appropriate legal basis for disclosure when the purpose is public health improvement rather than public health protection. Where health improvement, rather than protection, is the aim, there is no justification for discarding the additional safeguards associated with processing under Regulation 5.

  2. A Prediction Algorithm for Drug Response in Patients with Mesial Temporal Lobe Epilepsy Based on Clinical and Genetic Information (United States)

    Carvalho, Benilton S.; Bilevicius, Elizabeth; Alvim, Marina K. M.; Lopes-Cendes, Iscia


    Mesial temporal lobe epilepsy is the most common form of adult epilepsy in surgical series. Currently, the only characteristic used to predict poor response to clinical treatment in this syndrome is the presence of hippocampal sclerosis. Single nucleotide polymorphisms (SNPs) located in genes encoding drug transporter and metabolism proteins could influence response to therapy. Therefore, we aimed to evaluate whether combining information from clinical variables as well as SNPs in candidate genes could improve the accuracy of predicting response to drug therapy in patients with mesial temporal lobe epilepsy. For this, we divided 237 patients into two groups: 75 responsive and 162 refractory to antiepileptic drug therapy. We genotyped 119 SNPs in ABCB1, ABCC2, CYP1A1, CYP1A2, CYP1B1, CYP2C9, CYP2C19, CYP2D6, CYP2E1, CYP3A4, and CYP3A5 genes. We used 98 additional SNPs to evaluate population stratification. We assessed a first scenario using only clinical variables and a second one including SNP information. The random forests algorithm combined with leave-one-out cross-validation was used to identify the best predictive model in each scenario and compared their accuracies using the area under the curve statistic. Additionally, we built a variable importance plot to present the set of most relevant predictors on the best model. The selected best model included the presence of hippocampal sclerosis and 56 SNPs. Furthermore, including SNPs in the model improved accuracy from 0.4568 to 0.8177. Our findings suggest that adding genetic information provided by SNPs, located on drug transport and metabolism genes, can improve the accuracy for predicting which patients with mesial temporal lobe epilepsy are likely to be refractory to drug treatment, making it possible to identify patients who may benefit from epilepsy surgery sooner.

    Enhancing the competencies of health professionals is only one of the ways health care services can be improved. The management of information in particular has been shown to impact the quality of health care service delivery. A powerful approach is to improve the tools with which health and health-related data and information are collected stored accessed disseminated and used. This publication covers areas related to the management of patient information at three levels (local health care facility regional/district and national). It analyses the trends in the progression from paper-based inf

    Reiter, E R; Reiter, Ehud; Osman, Liesl


    Tailored patient information (TPI) systems are computer programs which produce personalised heath-information material for patients. TPI systems are of growing interest to the natural-language generation (NLG) community; many TPI systems have also been developed in the medical community, usually with mail-merge technology. No matter what technology is used, experience shows that it is not easy to field a TPI system, even if it is shown to be effective in clinical trials. In this paper we discuss some of the difficulties in fielding TPI systems. This is based on our experiences with 2 TPI systems, one for generating asthma-information booklets and one for generating smoking-cessation letters.

  5. Using information technology for patient education: realizing surplus value? (United States)

    Stoop, Arjen P; van't Riet, Annemarie; Berg, Marc


    Computer-based patient information systems are introduced to replace traditional forms of patient education like brochures, leaflets, videotapes and, to a certain extent, face-to-face communication. In this paper, we claim that though computer-based patient information systems potentially have many advantages compared to traditional means, the surplus value of these systems is much harder to realize than often expected. By reporting on two computer-based patient information systems, both found to be unsuccessful, we will show that building computer-based patient information systems for patient education requires a thorough analysis of the advantages and limitations of IT compared to traditional forms of patient education. When this condition is fulfilled, however, these systems have the potential to improve health status and to be a valuable supplement to (rather than a substitute for) traditional means of patient education.

  6. Atlas-based neuroinformatics via MRI: harnessing information from past clinical cases and quantitative image analysis for patient care. (United States)

    Mori, Susumu; Oishi, Kenichi; Faria, Andreia V; Miller, Michael I


    With the ever-increasing amount of anatomical information radiologists have to evaluate for routine diagnoses, computational support that facilitates more efficient education and clinical decision making is highly desired. Despite the rapid progress of image analysis technologies for magnetic resonance imaging of the human brain, these methods have not been widely adopted for clinical diagnoses. To bring computational support into the clinical arena, we need to understand the decision-making process employed by well-trained clinicians and develop tools to simulate that process. In this review, we discuss the potential of atlas-based clinical neuroinformatics, which consists of annotated databases of anatomical measurements grouped according to their morphometric phenotypes and coupled with the clinical informatics upon which their diagnostic groupings are based. As these are indexed via parametric representations, we can use image retrieval tools to search for phenotypes along with their clinical metadata. The review covers the current technology, preliminary data, and future directions of this field.

  7. Pharmacogenetic information for patients on drug labels. (United States)

    Haga, Susanne B; Mills, Rachel; Moaddeb, Jivan


    Advances in pharmacogenetic research have improved our understanding of adverse drug responses and have led to the development of pharmacogenetic tests and targeted drugs. However, the extent of the communication process and provision of information to patients about pharmacogenetics is unclear. Pharmacogenetic information may be included in sections of a drug's package insert intended for patients, which is provided directly to patients or communicated via the health provider. To determine what pharmacogenetic information, if any, is included in patient-targeted sections of the drug label, we reviewed the labels listed in the US Food and Drug Administration's Table of Pharmacogenomic Biomarkers in Drug Labels. To date, 140 drugs include pharmacogenetic-related information in the approved label. Our analysis revealed that pharmacogenetic information is included in patient-targeted sections for a minority (n=29; 21%) of drug labels, with no obvious pattern associated with the inclusion of pharmacogenetic information. Therefore, patients are unlikely to learn about pharmacogenetics through written materials dispensed with the drug. Given that there are also inconsistencies with regard to inclusion of pharmacogenetic information in the patient counseling information section, it is also unlikely that patients are receiving adequate pharmacogenetic information from their provider. The inconsistent presence of pharmacogenetic information in patient-targeted sections of drug labels suggests a need to review the criteria for inclusion of information in patient-targeted sections in order to increase consistency and patient knowledge of pharmacogenetic information.

  8. Supporting cancer patients' unanchored health information management with mobile technology. (United States)

    Klasnja, Predrag; Hartzler, Andrea; Powell, Christopher; Pratt, Wanda


    Cancer patients often need to manage care-related information when they are away from home, when they are experiencing pain or treatment side effects, or when their abilities to deal with information effectively are otherwise impaired. In this paper, we describe the results from a four-week evaluation of HealthWeaver Mobile, a mobile phone application that we developed to support such "unanchored" patient information activities. Based on experiences from nine cancer patients, our results indicate that HealthWeaver Mobile can help patients to access care-related information from anywhere, to capture information whenever a need arises, and to share information with clinicians during clinic visits. The enhanced ability to manage information, in turn, helps patients to manage their care and to feel more confident in their ability to stay in control of their information and their health.

  9. [Patient information and obtaining informed consent in laparoscopic surgery]. (United States)

    Rougé, C; Tuesch, J J; Casa, C; Ludes, B; Arnaud, J P


    Since the advent of laparoscopic surgery, the number of suits against surgeons has risen. One of the most frequent complaints is the lack of sufficient information. Physicians in France have a formal obligation to provide information in the contractual legal context established since 1936. This notion has been confirmed in several court cases. The requirement for patient informed consent has been confirmed by several decisions of the Appeals Court and is stated in the code of deontology. The value of classical oral information has been recently questioned in certain court cases. We analyse the current legal situation in France and try to define the content of information required in the case of laparoscopic surgery in addition to the way this information is provided and the means of obtaining informed consent. The information provided must be personalised. The patient must informed that laparoscopy remains a surgical operation. It is licit to warn the patient of predictable risks according to statistical probabilities, of the team's experience and of the patients own status including past history and psychological factors. A written statement may be prepared but must remain a document complementary to personalised oral information. The surgeon must obtain and assure good patient comprehension. The surgical community should publish risk rates in order for surgeons to have reliable references which can be used to define the notion of exceptional risk.

    Objective:High-quality information provision can allow stroke patients to effectively participate in healthcare decision-making,better manage the stroke,and make a good recovery.In this study,we reviewed information needs of stroke patients,methods for providing information to patients,and considerations needed by the information providers.Data Sources:The literature concerning or including information provision for patients with stroke in English was collected from PubMed published from 1990 to 2015.Study Selection:We included all the relevant articles on information provision for stroke patients in English,with no limitation of study design.Results:Stroke is a major public health concern worldwide.High-quality and effective health information provision plays an essential role in helping patients to actively take part in decision-making and healthcare,and empowering them to effectively self-manage their long-standing chronic conditions.Different methods for providing information to patients have their relative merits and suitability,and as a result,the effective strategies taken by health professionals may include providing high-quality information,meeting patients' individual needs,using suitable methods in providing information,and maintaining active involvement of patients.Conclusions:It is suggested that to enable stroke patients to access high-quality health information,greater efforts need to be made to ensure patients to receive accurate and current evidence-based information which meets their individual needs.Health professionals should use suitable information delivery methods,and actively involve stroke patients in information provision.

  12. Informing the cancer patient and family. (United States)

    Kallergis, G


    One of the questions the therapist poses himself while informing a patient is: whom shall I inform about the diagnosis, treatment and prognosis? If we unconditionally accepted the view that information belongs to the patient from an ethical and legal standpoint, we would automatically exclude the partner and the family. Therefore, the therapist should raise another question: what is the benefit to the patient? To answer the question and the resulting dilemma, we have to leverage the long experience of family therapy and tailor it to the cases we are dealing with. It should be taken into consideration that patient and family are a dynamic system which was balanced before the onset of the disease, but is now disrupted, entering into crisis. Therefore, denial mechanism and personality characteristics we have previously elaborated on, and communication among members play a crucial role in determining the information strategy and the way family should be approached. The steps to approach the patient - family are: 1) Firstly, we evaluate the patient's degree of denial and personality characteristics. Then we receive information about the patient's family so that we can have a rough idea about intrafamily dynamics. 2) Then we gather information from the nurses about the family atmosphere: simple information about the patient's and relatives' relationship like who comes to the hospital, who shows interest in the patient, whether someone is being quarrelsome or not are crucial to assess the dynamics of their relationships. 3) We summon patient and family members in our office. 4) We decide on the steps to inform the patient, and we apply them. Involving family members with the patient seems to improve the results of information and forge concession and therapeutic alliance, which are necessary parameters in the therapeutic follow-up. Usually, doctors and nurses approach patient and family using their experience. Therefore, we need a training that will equip health

  13. Roles for Information professionals in patient education: Librarians' perspective

    Susan L. MacDonald


    Full Text Available Through an examination of librarians’ contributions to the PEPTalk research project, this article highlights roles for information professionals at various stages in the design and clinical implementation of an information system that delivers patient education. The Personal Education Plan (PEPTalk was a collaborative, multi-disciplinary research project (2005-2006 based at the University Health Network’s Princess Margaret Hospital that designed an information system to provide web-based health information resources to both patients and clinicians under a shared umbrella of patient education. This article provides an overview of the PEPTalk project methods and outcomes, and documents the contributions of librarians throughout the design and clinical implementation stages of the project. Librarians brought expertise about information seeking behaviours of both patients and clinicians to the project; liaised across institutional and professional boundaries; developed a classification system for online learning objects, and educated project team about information and health literacies. The contributions of librarians on the PEPTalk project illustrate the need for boundary spanners, information brokers, knowledge translators, and change champions in the design and implementation of patient education delivery systems. There are new roles emergent at the intersections of clinical practice and health information provision. There is a need for the traditional skills and expertise of librarians and other information professionals in tailoring health information. Yet the design and implementation of patient education systems also require the development of new skills and the application of advanced information literacy as it pertains to both clinicians and patients.

  17. Extracting Information from Electronic Medical Records to Identify the Obesity Status of a Patient Based on Comorbidities and Bodyweight Measures. (United States)

    Figueroa, Rosa L; Flores, Christopher A


    Obesity is a chronic disease with an increasing impact on the world's population. In this work, we present a method of identifying obesity automatically using text mining techniques and information related to body weight measures and obesity comorbidities. We used a dataset of 3015 de-identified medical records that contain labels for two classification problems. The first classification problem distinguishes between obesity, overweight, normal weight, and underweight. The second classification problem differentiates between obesity types: super obesity, morbid obesity, severe obesity and moderate obesity. We used a Bag of Words approach to represent the records together with unigram and bigram representations of the features. We implemented two approaches: a hierarchical method and a nonhierarchical one. We used Support Vector Machine and Naïve Bayes together with ten-fold cross validation to evaluate and compare performances. Our results indicate that the hierarchical approach does not work as well as the nonhierarchical one. In general, our results show that Support Vector Machine obtains better performances than Naïve Bayes for both classification problems. We also observed that bigram representation improves performance compared with unigram representation.

  18. A Computerized Hospital Patient Information Management System (United States)

    Wig, Eldon D.


    The information processing needs of a hospital are many, with varying degrees of complexity. The prime concern in providing an integrated hospital information management system lies in the ability to process the data relating to the single entity for which every hospital functions - the patient. This paper examines the PRIMIS computer system developed to accommodate hospital needs with respect to a central patient registry, inpatients (i.e., Admission/Transfer/Discharge), and out-patients. Finally, the potential for expansion to permit the incorporation of more hospital functions within PRIMIS is examined.

    It is important for the patient to have access to personal medical information in order to manage information for increased quality of medical care and life. The paper presents a module added to an Obstetrics-Gynaecology Department information system (OGD IS) supporting patient empowerment. The patient is accessing the system easily using laptops or mobile devices. The application accessed by the patient is web-based, implemented in Visual Studio. NET, using ASP.NET pages and C# language, and the application is published in the Windows Azure cloud. The solution is user friendly using familiar devices and is ubiquitous using the cloud solution. A module for translating medical terms in colloquial ones is integrated in the system. For certain situations the patient will get information related to life style influencing health status as how and what to eat or what type of exercise it is recommended.

  20. A web-based laboratory information system to improve quality of care of tuberculosis patients in Peru: functional requirements, implementation and usage statistics

    Directory of Open Access Journals (Sweden)

    Yale Gloria


    Full Text Available Abstract Background Multi-drug resistant tuberculosis patients in resource-poor settings experience large delays in starting appropriate treatment and may not be monitored appropriately due to an overburdened laboratory system, delays in communication of results, and missing or error-prone laboratory data. The objective of this paper is to describe an electronic laboratory information system implemented to alleviate these problems and its expanding use by the Peruvian public sector, as well as examine the broader issues of implementing such systems in resource-poor settings. Methods A web-based laboratory information system "e-Chasqui" has been designed and implemented in Peru to improve the timeliness and quality of laboratory data. It was deployed in the national TB laboratory, two regional laboratories and twelve pilot health centres. Using needs assessment and workflow analysis tools, e-Chasqui was designed to provide for improved patient care, increased quality control, and more efficient laboratory monitoring and reporting. Results Since its full implementation in March 2006, 29,944 smear microscopy, 31,797 culture and 7,675 drug susceptibility test results have been entered. Over 99% of these results have been viewed online by the health centres. High user satisfaction and heavy use have led to the expansion of e-Chasqui to additional institutions. In total, e-Chasqui will serve a network of institutions providing medical care for over 3.1 million people. The cost to maintain this system is approximately US$0.53 per sample or 1% of the National Peruvian TB program's 2006 budget. Conclusion Electronic laboratory information systems have a large potential to improve patient care and public health monitoring in resource-poor settings. Some of the challenges faced in these settings, such as lack of trained personnel, limited transportation, and large coverage areas, are obstacles that a well-designed system can overcome. e-Chasqui has the

  1. The Influence of Health Literacy and Patient Activation on Patient Information Seeking and Sharing. (United States)

    Ledford, Christy J W; Cafferty, Lauren A; Russell, Travis C


    This study provided an assessment of how patients looked for information to prepare for a clinical appointment and whether they shared those findings with their provider. A cross-sectional survey allowed insight into patient attitudes, motivations, and behavior in clinical real time. At two hospital-based clinics, 243 patients completed surveys before and after clinical appointments. Younger patients with higher communicative and critical health literacy prepared for clinical appointments with information searches. The predicted association of health literacy and patient activation with information sharing was not supported. This study shows that patients with higher patient activation perceived that their providers responded more positively to patient-obtained medical information. The role of critical health literacy may show that individuals choosing to seek information are considering not just their ability to conduct the search but also their ability to synthesize and critically analyze the results of the information search. An implication for providers is to become skilled in directly asking or passively surveying what outside information sources the patient has engaged with, no matter if the patient does or does not introduce the information.

    Conell, Jörn; Bauer, Rita; Glenn, Tasha


    BACKGROUND: Information seeking is an important coping mechanism for dealing with chronic illness. Despite a growing number of mental health websites, there is little understanding of how patients with bipolar disorder use the Internet to seek information. METHODS: A 39 question, paper......-based, anonymous survey, translated into 12 languages, was completed by 1222 patients in 17 countries as a convenience sample between March 2014 and January 2016. All patients had a diagnosis of bipolar disorder from a psychiatrist. Data were analyzed using descriptive statistics and generalized estimating...... equations to account for correlated data. RESULTS: 976 (81 % of 1212 valid responses) of the patients used the Internet, and of these 750 (77 %) looked for information on bipolar disorder. When looking online for information, 89 % used a computer rather than a smartphone, and 79 % started with a general...

  4. Isotope-based quantum information

    CERN Document Server

    G Plekhanov, Vladimir


    The present book provides to the main ideas and techniques of the rapid progressing field of quantum information and quantum computation using isotope - mixed materials. It starts with an introduction to the isotope physics and then describes of the isotope - based quantum information and quantum computation. The ability to manipulate and control electron and/or nucleus spin in semiconductor devices provides a new route to expand the capabilities of inorganic semiconductor-based electronics and to design innovative devices with potential application in quantum computing. One of the major challenges towards these objectives is to develop semiconductor-based systems and architectures in which the spatial distribution of spins and their properties can be controlled. For instance, to eliminate electron spin decoherence resulting from hyperfine interaction due to nuclear spin background, isotopically controlled devices are needed (i.e., nuclear spin-depleted). In other emerging concepts, the control of the spatial...

  7. Scoliosis related information on the internet in China: can patients benefit from this information?

    Directory of Open Access Journals (Sweden)

    Hongda Bao

    Full Text Available There has been an increasing popularity of searching health related information online in recent years. Despite that considerable amount of scoliosis patients have shown interest in obtaining scoliosis information through Internet, previous studies have demonstrated poor quality of online information. However, this conclusion may vary depending on region and culture. Since China has a restricted Internet access outside of its borders, the aim of this study is to evaluate the quality of scoliosis information available online using recognized scoring systems and to analyze the Internet as a source of health information in China.A survey-based questionnaire was distributed to 280 respondents at outpatient clinics. Information on demographics and Internet use was collected. Binary logistic analysis was performed to identify possible predictors for the use of Internet. In addition, the top 60 scoliosis related websites assessed through 4 search engines were reviewed by a surgeon and the quality of online information was evaluated using DISCERN score and JAMA benchmark.Use of the Internet as a source for scoliosis related information was confirmed in 87.8% of the respondents. College education, Internet access at home and urban residence were identified as potential predictors for Internet use. However, the quality of online scoliosis related information was poor with an average DISCERN score of 27.9±11.7 and may be misleading for scoliosis patients.The study outlines the profile of scoliosis patients who use the Internet as a source of health information. It was shown that 87.8% of the scoliosis patients in outpatient clinics have searched for scoliosis related information on Internet. Urban patients, higher education and Internet access at home were identified as potential predictors for Internet search. However, the overall quality of online scoliosis related information was poor and confusing. Physician based websites seemed to contain more

  9. Effective information spreading based on local information in correlated networks (United States)

    Gao, Lei; Wang, Wei; Pan, Liming; Tang, Ming; Zhang, Hai-Feng


    Using network-based information to facilitate information spreading is an essential task for spreading dynamics in complex networks. Focusing on degree correlated networks, we propose a preferential contact strategy based on the local network structure and local informed density to promote the information spreading. During the spreading process, an informed node will preferentially select a contact target among its neighbors, basing on their degrees or local informed densities. By extensively implementing numerical simulations in synthetic and empirical networks, we find that when only consider the local structure information, the convergence time of information spreading will be remarkably reduced if low-degree neighbors are favored as contact targets. Meanwhile, the minimum convergence time depends non-monotonically on degree-degree correlation, and a moderate correlation coefficient results in the most efficient information spreading. Incorporating the local informed density information into contact strategy, the convergence time of information spreading can be further reduced, and be minimized by an moderately preferential selection.

  10. Patients' feelings about hand washing, MRSA status and patient information. (United States)

    Duncan, Christopher Paul; Dealey, Carol

    The purpose of this study was to explore patient opinion about asking healthcare professionals to wash their hands before a clinical procedure and to explore if methicillin-resistant Staphylococcus aureus (MRSA) status and access to patient information about infection control would influence the patients' anxiety about asking. A descriptive survey was undertaken using a semi-structured questionnaire. The questionnaire was distributed to a randomized convenience sample of 185 inpatients across all departments of an acute NHS Trust hospital (response rate 58.9%). Spearman's rank order and Kendall Tau-b tests were used to analyse specific correlations. Respondents were more confident than anxious about being involved in a campaign that empowered patients to ask staff to wash their hands. Patients were more anxious to ask if their previous admission episodes were fewer, if their knowledge of MRSA was high and if there was less information about infection control available. Patients who had contracted MRSA in the past were less anxious, as they had a better understanding of the disease. In addition, more patients felt less anxious about asking staff to wash their hands if staff wore a badge saying 'It's OK to ask'.

    Truccolo, Ivana; Bufalino, Rosaria; Annunziata, Maria Antonietta; Caruso, Anita; Costantini, Anna; Cognetti, Gaetana; Florita, Antonio; Pero, Dina; Pugliese, Patrizia; Tancredi, Roberta; De Lorenzo, Francesco


    The international literature data report that good information and communication are fundamental components of a therapeutic process. They contribute to improve the patient-health care professional relationship, to facilitate doctor-patient relationships, therapeutic compliance and adherence, and to the informed consent in innovative clinical trials. We report the results of a multicentric national initiative that developed a 17-information-structure network: 16 Information Points located in the major state-funded certified cancer centers and general hospitals across Italy and a national Help-line at the nonprofit organization AIMaC (the Italian oncologic patients, families and friends association), and updated the already existing services with the aim to create the National Cancer Information Service (SION). The project is the result of a series of pilot and research projects funded by the Italian Ministry of Health. The Information Service model proposed is based on some fundamental elements: 1) human interaction with experienced operators, adequately trained in communication and information, complemented with 2) virtual interaction (Help line, Internet, blog, forum and social network); 3) informative material adequate for both scientific accuracy and communicative style; 4) adequate locations for appropriate positioning and privacy (adequate visibility); 5) appropriate advertising. First results coming from these initiatives contributed to introduce issues related to "Communication and Information to patients" as a "Public Health Instrument" to the National Cancer Plan approved by the Ministry of Health for the years 2010-2012.

  12. Information-seeking Behavior and Information Needs in Patients With Amyotrophic Lateral Sclerosis: Analyzing an Online Patient Community. (United States)

    Oh, Juyeon; Kim, Jung A


    A few studies have examined the specific informational needs of the population with amyotrophic lateral sclerosis. The aims of this study were to describe the information-seeking behavior and information needs of patients with amyotrophic lateral sclerosis and their families in Korea by analyzing messages from an online patient community. A total of 1047 messages from the question and answer forum of the "Lou Gehrig's Disease Network" ( from January 2010 to September 2015 were collected. The word frequency, main questions, and asker of the messages were analyzed and coded. Terms such as "hospital," "mother," "father," "gastrostomy," and "ALS" were most frequently identified. The most commonly mentioned main topic was about disease-specific information, while the most frequent subcategory was symptoms or management of symptoms. Other prominent categories concerned information about treatment, rehabilitation, and the medical system. The people who wrote the questions were mostly the son/daughter of patients with amyotrophic lateral sclerosis. Patients with amyotrophic lateral sclerosis and their family members commonly obtained information by posting their inquiries online and have a variety of questions regarding amyotrophic lateral sclerosis in this study. The findings of this study can be used as a base of information for developing educational programs and resources for patients with amyotrophic lateral sclerosis and their families.

  13. Processing of laser Doppler flowmetry signals from healthy subjects and patients with varicose veins: Information categorisation approach based on intrinsic mode functions and entropy computation. (United States)

    Humeau-Heurtier, Anne; Klonizakis, Markos


    The diagnosis of pathologies from signal processing approaches has shown to be of importance. This can provide noninvasive information at the earliest stage. In this work, the problem of categorising - in a quantifiable manner - information content of microvascular blood flow signals recorded in healthy participants and patients with varicose veins is addressed. For this purpose, laser Doppler flowmetry (LDF) signals - that reflect microvascular blood flow - recorded both at rest and after acetylcholine (ACh) stimulation (an endothelial-dependent vasodilator) are analyzed. Each signal is processed with the empirical mode decomposition (EMD) to obtain its intrinsic mode functions (IMFs). An entropy measure of each IMFs is then computed. The results show that IMFs of LDF signals have different complexity for different physiologic/pathological states. This is true both at rest and after ACh stimulation. Thus, the proposed framework (EMD + entropy computation) may be used to gain a noninvasive understanding of LDF signals in patients with microvascular dysfunctions.

  15. Informal patient payments in oncology practice

    Directory of Open Access Journals (Sweden)

    Fomenko, Tetiana


    Full Text Available BACKGROUND: In Europe, new cases of cancer are diagnosed in 4 million people yearly, of whom 837 000 die. In Ukraine of 160 000 new cases almost 100 000 die. With proper treatment, one third of cancer cases is curable, but informal payments (IPP in health care limit access to treatment. We aimed to explore the experience of people treated for cancer to identify obstacles in obtaining health care and the expert opinion about health care for cancer patients in Ukraine.METHODS: The study is exploratory. Semi-structured in-depth interviews were conducted with 15 convenience sample patients or their relatives as well as with three experts between October 2011 – April 2012. RESULTS. Solicitation or receipt of IPP depends on the organizational culture. Respondents do not mind about IPP, but want this to be their own decision. IPP are often considered a “thank” to the medical staff for the service. The significant percentage of expenditures while in treatment for patients is due to purchases of medicines at their own expense. The problem of a long process of diagnostics and incomplete information by the medical staff about the stage of cancer and possible prognoses are essential for the respondents. According to experts not sufficient number of specialists and equipment for proper diagnosis and treatment is another problem. The attitude of medical staff to the patient with cancer largely depends on the personal features of the staff.CONCLUSIONS: Significant problems perceived by cancer patients are related to purchase of medicines at their own expense, structural and organizational features of hospitals, where they are staying for the treatment. Informal payments largely depend on the personal qualities of medical staff. The government must ensure fairness and equal access in getting care in oncology practice because it mainly affects the health of the nation.

  16. Patient information and education with modern media: the Spine Society of Europe Patient Line. (United States)

    Pellisé, Ferran; Sell, P


    The role of the patient as an active partner in health care, and not just a passive object of diagnostic testing and medical treatment, is widely accepted. Providing information to patients is considered a crucial issue and the central focus in patient educational activities. It is necessary to educate patients on the nature of the outcomes and the benefits and risks of the procedures to involve them in the decision-making process and enable them to achieve fully informed consent. Information materials must contain scientifically reliable information and be presented in a form that is acceptable and useful to patients. Given the mismatch between public beliefs and current evidence, strategies for changing the public perceptions are required. Traditional patient education programmes have to face the potential barriers of storage, access problems and the need to keep content materials up to date. A computer-based resource provides many advantages, including "just-in-time" availability and a private learning environment. The use of the Internet for patient information needs will continue to expand as Internet access becomes readily available. However, the problem is no longer in finding information, but in assessing the credibility and validity of it. Health Web sites should provide health information that is secure and trustworthy. The large majority of the Web sites providing information related to spinal disorders are of limited and poor quality. Patient Line (PL), a patient information section in the Web site of Eurospine, was born in 2005 to offer patients and the general population the accumulated expertise represented by the members of the society and provide up-to-date information related to spinal disorders. In areas where evidence is scarce, Patient Line provides a real-time opinion of the EuroSpine membership. The published data reflect the pragmatic and the common sense range of treatments offered by the Eurospine membership. The first chapters have been

  19. Intraoperative patient information handover between anesthesia providers (United States)

    Choromanski, Dominik; Frederick, Joel; McKelvey, George Michael; Wang, Hong


    Abstract Currently, no reported studies have evaluated intraoperative handover among anesthesia providers. Studies on anesthetic handover in the US recovery room setting observed that handover processes are insufficient and, in many instances, significant intraoperative events are disregarded. An online survey tool was sent to anesthesia providers at US anesthesia residency programs nationwide (120 out of the 132 US programs encompassing around 4500 residents and their academic MDAs) and a smaller survey selection of CRNAs (10 institutions about 300 CRNAs in the metropolitan area of Detroit, MI, USA) to collect information on handover practices. The response rate to this survey (n = 216) was comprised of approximately 5% (n = 71) of the resident population in US anesthesia programs, 5% (n = 87) of MDAs , and 20% (n = 58) of the CRNAs. Out of all respondents (n = 212), 49.1 % had no hand-over protocol at their institution and 88% of respondents who did have institutional handover protocols believed them insufficient for effective patient handover. In addiiton, 84.8% of all responders reported situations where there was insufficient information received during a patient handover. Only 7% of the respondents reported never experiencing complications or mismanagement due to poor or incomplete hand-overs. In contrast, 60% reported rarely having complications, 31% reported sometimes having complications, and 3% reported frequent complications. In conclusion, handover transition of patient care is a vulnerable and potentially life-threatening event in the operating room. Our preliminary study suggests that current intraoperatvive handover practices among anesthesia providers are suboptimal and that national patient handover guidelines are required to improve patient safety.

    Gao, Lei; Pan, Liming; Tang, Ming; Zhang, Hai-Feng


    Using network-based information to facilitate information spreading is an essential task for spreading dynamics in complex networks, which will benefit the promotion of technical innovations, healthy behaviors, new products, etc. Focusing on degree correlated networks, we propose a preferential contact strategy based on the local network structure and local informed density to promote the information spreading. During the spreading process, an informed node will preferentially select a contact target among its neighbors, basing on their degrees or local informed densities. By extensively implementing numerical simulations in synthetic and empirical networks, we find that when only consider the local structure information, the convergence time of information spreading will be remarkably reduced if low-degree neighbors are favored as contact targets. Meanwhile, the minimum convergence time depends non-monotonically on degree-degree correlation, and moderate correlation coefficients result in most efficient info...

  3. Management Guidelines for Patients Choosing the Renal Supportive Care (RSC) Pathway: Information and Web-based Treatment Protocols Available to All. (United States)

    Crail, Susan M


    Available guidelines fall into 2 categories - medication guides and service provision guides Few guidelines exist for the management of patients choosing to not have dialysis apart from those covering end of life (EOL) management and general ones for the management of chronic kidney disease. Most guidelines are only based on low level evidence, relying on expert opinion or current practice. This limits their usage when advising on matters such as trials of dialysis and caution should be applied when discussing these matters. More data is needed before firmer recommendations can be made. Units in Australia and New Zealand should consider maintaining registers of 'at risk' patients to allow greater input into symptom management and end-of-life support.

    Alessandra De Palma


    Full Text Available BACKGROUND Communication is very important in medical activity, particularly to maintain or re-establish trust-based relationships between patients, doctors, nurses and all the people who work in Hospital or for the Italian National Health Service. Health services include the relationship between doctors and patients: the partnership is important as much as the technical ability in Medicine. But it is difficult to learn empathy: doctors are not taught about that at University, nor afterwards, at least not sufficiently. CONCLUSIONS The informed consent form, even if it is very detailed, is not the real answer to that problem.

  8. Spatial Information Based Medical Image Registration using Mutual Information

    Directory of Open Access Journals (Sweden)

    Benzheng Wei


    Full Text Available Image registration is a valuable technique for medical diagnosis and treatment. Due to the inferiority of image registration using maximum mutual information, a new hybrid method of multimodality medical image registration based on mutual information of spatial information is proposed. The new measure that combines mutual information, spatial information and feature characteristics, is proposed. Edge points are used as features, obtained from a morphology gradient detector. Feature characteristics like location, edge strength and orientation are taken into account to compute a joint probability distribution of corresponding edge points in two images. Mutual information based on this function is minimized to find the best alignment parameters. Finally, the translation parameters are calculated by using a modified Particle Swarm Optimization (MPSO algorithm. The experimental results demonstrate the effectiveness of the proposed registration scheme.

    Drug adherence is central to the treatment of dementia, which might reduce compliance due to memory loss, particularly among home-based patients with dementia. In order to improve drug adherence, we suggest the efficient and effective supervised administration by use of information communication technology(ICT). ICT makes face-to-face real-time communication possible, and it also enables picture sharing. Therefore, it might be useful to apply ICT to controlling and supervising medication for patients with dementia to improve drug adherence. Accordingly, we enrolled patients who were supposed to take a newly prescribed anti-dementia patch containing the choline esterase inhibitor rivastigmine(Rivastach®)and investigated the effect of ICT-based intervention for drug adherence, emotional change, and cognitive change, utilizing Skype, a free communication software program. Scheduled Skype interventions increased drug adherence ratio, levels of subjective satisfaction, and instrumental activities of daily living(IADL). Furthermore, we can provide patients and their caregivers with a feeling of safety through regular bidirectional communication, as patients can easily consult medical staff regarding the adverse effects of newly prescribed drugs. Instead of frequent visits to their primary physicians, ICT-based communications can be used as a substitute for supervision of medication, given the availability of the telecommunication system. By directly connecting the medical institution to the home, we expect that this ICT-based system will expand into the geriatric care field, including the care of elderly individuals living alone.

  11. Cancer Carepartners: Improving patients' symptom management by engaging informal caregivers

    Directory of Open Access Journals (Sweden)

    Silveira Maria J


    Full Text Available Abstract Background Previous studies have found that cancer patients undergoing chemotherapy can effectively manage their own symptoms when given tailored advice. This approach, however, may challenge patients with poor performance status and/or emotional distress. Our goal is to test an automated intervention that engages a friend or family member to support a patient through chemotherapy. Methods/Design We describe the design and rationale of a randomized, controlled trial to assess the efficacy of 10 weeks of web-based caregiver alerts and tailored advice for helping a patient manage symptoms related to chemotherapy. The study aims to test the primary hypothesis that patients whose caregivers receive alerts and tailored advice will report less frequent and less severe symptoms at 10 and 14 weeks when compared to patients in the control arm; similarly, they will report better physical function, fewer outpatient visits and hospitalizations related to symptoms, and greater adherence to chemotherapy. 300 patients with solid tumors undergoing chemotherapy at two Veteran Administration oncology clinics reporting any symptom at a severity of ≥4 and a willing informal caregiver will be assigned to either 10 weeks of automated telephonic symptom assessment (ATSA alone, or 10 weeks of ATSA plus web-based notification of symptom severity and problem solving advice to their chosen caregiver. Patients and caregivers will be surveyed at intake, 10 weeks and 14 weeks. Both groups will receive standard oncology, hospice, and palliative care. Discussion Patients undergoing chemotherapy experience many symptoms that they may be able to manage with the support of an activated caregiver. This intervention uses readily available technology to improve patient caregiver communication about symptoms and caregiver knowledge of symptom management. If successful, it could substantially improve the quality of life of veterans and their families during the stresses of

  17. Tumor information extraction in radiology reports for hepatocellular carcinoma patients (United States)

    Yim, Wen-wai; Denman, Tyler; Kwan, Sharon W.; Yetisgen, Meliha


    Hepatocellular carcinoma (HCC) is a deadly disease affecting the liver for which there are many available therapies. Targeting treatments towards specific patient groups necessitates defining patients by stage of disease. Criteria for such stagings include information on tumor number, size, and anatomic location, typically only found in narrative clinical text in the electronic medical record (EMR). Natural language processing (NLP) offers an automatic and scale-able means to extract this information, which can further evidence-based research. In this paper, we created a corpus of 101 radiology reports annotated for tumor information. Afterwards we applied machine learning algorithms to extract tumor information. Our inter-annotator partial match agreement scored at 0.93 and 0.90 F1 for entities and relations, respectively. Based on the annotated corpus, our sequential labeling entity extraction achieved 0.87 F1 partial match, and our maximum entropy classification relation extraction achieved scores 0.89 and 0. 74 F1 with gold and system entities, respectively.

  18. A Web-Based Psychoeducational Program for Informal Caregivers of Patients With Alzheimer’s Disease: A Pilot Randomized Controlled Trial (United States)

    Wrobel, Jérémy; Cantegreil-Kallen, Inge; Dub, Timothée; Rouquette, Alexandra; Rigaud, Anne-Sophie


    Background Although several face-to-face programs are dedicated to informal caregivers of persons with dementia, they are not always accessible to overburdened or isolated caregivers. Based on a face-to-face intervention program, we adapted and designed a Web-based fully automated psychoeducational program (called Diapason) inspired by a cognitive approach. Objective This study aimed to evaluate through a pilot unblinded randomized controlled trial the efficacy and acceptability of a Web-based psychoeducational program for informal caregivers of persons with Alzheimer’s disease (PWAD) based on a mixed methods research design. Methods We recruited and randomized offline 49 informal caregivers of a PWAD in a day care center in Paris, France. They either received the Web-based intervention and usual care for 3 months (experimental group, n=25) or only usual care (control group, n=24). Caregivers’ perceived stress (PSS-14, primary outcome), self-efficacy, burden, perceived health status, and depression (secondary outcomes) were measured during 3 face-to-face on-site visits: at baseline, at the end of the program (month 3), and after follow-up (month 6). Additionally, semistructured interviews were conducted with experimental group caregivers at month 6 and examined with thematic analysis. Results Intention-to-treat analysis did not show significant differences in self-perceived stress between the experimental and control groups (P=.98). The experimental group significantly improved their knowledge of the illness (d=.79, P=.008) from baseline to month 3. Of the 25 participants allocated to the experimental group, 17 (71%) finished the protocol and entirely viewed at least 10 of 12 online sessions. On average, participants used the website 19.72 times (SD 12.88) and were connected for 262.20 minutes (SD 270.74). The results of the satisfaction questionnaire showed that most participants considered the program to be useful (95%, 19/20), clear (100%, 20/20), and

    In conventional image matching methods, the image matching process is mostly based on image statistic information. One aspect neglected by all these methods is that there is much fuzzy information contained in these images. A new fuzzy matching algorithm based on fuzzy similarity for navigation is presented in this paper. Because the fuzzy theory is of the ability of making good description of the fuzzy information contained in images, the image matching method based on fuzzy similarity would look forward to producing good performance results. Experimental results using matching algorithm based on fuzzy information also demonstrate its reliability and practicability.

  4. Patient-Reported Safety Information: A Renaissance of Pharmacovigilance? (United States)

    Härmark, Linda; Raine, June; Leufkens, Hubert; Edwards, I Ralph; Moretti, Ugo; Sarinic, Viola Macolic; Kant, Agnes


    The role of patients as key contributors in pharmacovigilance was acknowledged in the new EU pharmacovigilance legislation. This contains several efforts to increase the involvement of the general public, including making patient adverse drug reaction (ADR) reporting systems mandatory. Three years have passed since the legislation was introduced and the key question is: does pharmacovigilance yet make optimal use of patient-reported safety information? Independent research has shown beyond doubt that patients make an important contribution to pharmacovigilance signal detection. Patient reports provide first-hand information about the suspected ADR and the circumstances under which it occurred, including medication errors, quality failures, and 'near misses'. Patient-reported safety information leads to a better understanding of the patient's experiences of the ADR. Patients are better at explaining the nature, personal significance and consequences of ADRs than healthcare professionals' reports on similar associations and they give more detailed information regarding quality of life including psychological effects and effects on everyday tasks. Current methods used in pharmacovigilance need to optimise use of the information reported from patients. To make the most of information from patients, the systems we use for collecting, coding and recording patient-reported information and the methodologies applied for signal detection and assessment need to be further developed, such as a patient-specific form, development of a severity grading and evolution of the database structure and the signal detection methods applied. It is time for a renaissance of pharmacovigilance.

  5. Internet health information in the patient-provider dialogue. (United States)

    Hong, Traci


    A patient discussing Internet health information with a health care provider (referred to as "patient-provider communication about Internet health information") can contribute positively to health outcomes. Although research has found that once Internet access is achieved, there are no ethnic differences in Internet health information seeking, it is unclear if there are ethnic differences in patient-provider communication about Internet health information. To help fill this gap in the literature, the National Cancer Institute's Health Information National Trends Survey 2005 was analyzed with Stata 9. Two sets of logistic regression analyses were conducted, one for a subsample of Internet users (n = 3,244) and one for a subsample of Internet users who are first-generation immigrants (n = 563). The dependent variable was patient-provider communication about Internet health information, which assessed whether survey participants had discussed online health information with a health care provider. The predictor variables included trust of health care provider, trust of online health information, Internet use, health care coverage, frequency of visits to health care provider, health status, and demographics. Among all Internet users, Whites had higher levels of patient-provider communication about Internet health information than Blacks and Asians. Similarly, among Internet users who are immigrants, Whites had higher levels of patient-provider communication about Internet health information than Blacks and Asians. While the digital divide is narrowing in terms of Internet access, racial differences in patient-provider communication about Internet health information may undermine the potential benefits of the information age.

  9. Navigating the cancer information environment: The reciprocal relationship between patient-clinician information engagement and information seeking from nonmedical sources. (United States)

    Moldovan-Johnson, Mihaela; Tan, Andy S L; Hornik, Robert C


    Prior theory has argued and empirical studies have shown that cancer patients rely on information from their health care providers as well as lay sources to understand and make decisions about their disease. However, research on the dynamic and interdependent nature of cancer patients' engagement with different information sources is lacking. This study tested the hypotheses that patient-clinician information engagement and information seeking from nonmedical sources influence one another longitudinally among a representative cohort of 1,293 cancer survivors in Pennsylvania. The study hypotheses were supported in a series of lagged multiple regression analyses. Baseline seeking information from nonmedical sources positively predicted subsequent patient-clinician information engagement at 1-year follow-up. The reverse relationship was also statistically significant; baseline patient-clinician information engagement positively predicted information seeking from nonmedical sources at follow-up. These findings suggest that cancer survivors move between nonmedical and clinician sources in a dynamic way to learn about their disease.

  10. Unified framework for information integration based on information geometry. (United States)

    Oizumi, Masafumi; Tsuchiya, Naotsugu; Amari, Shun-Ichi


    Assessment of causal influences is a ubiquitous and important subject across diverse research fields. Drawn from consciousness studies, integrated information is a measure that defines integration as the degree of causal influences among elements. Whereas pairwise causal influences between elements can be quantified with existing methods, quantifying multiple influences among many elements poses two major mathematical difficulties. First, overestimation occurs due to interdependence among influences if each influence is separately quantified in a part-based manner and then simply summed over. Second, it is difficult to isolate causal influences while avoiding noncausal confounding influences. To resolve these difficulties, we propose a theoretical framework based on information geometry for the quantification of multiple causal influences with a holistic approach. We derive a measure of integrated information, which is geometrically interpreted as the divergence between the actual probability distribution of a system and an approximated probability distribution where causal influences among elements are statistically disconnected. This framework provides intuitive geometric interpretations harmonizing various information theoretic measures in a unified manner, including mutual information, transfer entropy, stochastic interaction, and integrated information, each of which is characterized by how causal influences are disconnected. In addition to the mathematical assessment of consciousness, our framework should help to analyze causal relationships in complex systems in a complete and hierarchical manner.

  12. [The information of the schizophrenic patient: actuality]. (United States)

    Palazzolo, J; Brousse, G; Favre, P; Llorca, P-M


    schizophrenia can come alive talking about things in the past before they became ill. It's as if their life grinded to halt when they became sick. I'm stuck in the mid seventies, and that's the music I like. Everybody I know with schizophrenia is quite isolated socially and I don't really know why. That is especially true for the older people in my age group. Younger people seem to be doing much better. Many still live with their parents. Most older people live alone. There is also the odd person who recovers well, returns to a career, and marries someone without schizophrenia. In cases where marriage predates the onset of schizophrenia, the outcome is often divorce although women are more likely to stick with their husbands with schizophrenia than vice versa, especially if there are already children. I hope the next generation who appears to be less disabled survives better than people of my age with schizophrenia. The goal of community integration is one that requires: more effective treatments and/or more financial support and/or a compassionate non-discriminating community. The combination of early diagnosis and atypical medications will change the face of schizophrenia. I'm not expecting more financial support from the government, but many more people with schizophrenia will start working again instead. Their social networks will develop but social networks are probably the hardest hit in schizophrenia. It's better that you never lose your friends in the first place". This testimony shows how the information of the schizophrenic patient is necessary, and underlines the importance of the relationships between the patient and his family. Our article insists on this theme, rarely developed in the literature.

  14. Associations Between Patient Characteristics and the Amount of Arthritis Medication Information Patients Receive. (United States)

    Geryk, Lorie Love; Blalock, Susan; DeVellis, Robert F; Morella, Kristen; Carpenter, Delesha Miller


    Little is known about factors associated with the receipt of medication information among arthritis patients. This study explores information source receipt and associations between demographic and clinical/patient characteristics and the amount of arthritis medication information patients receive. Adult patients with osteoarthritis (OA) or rheumatoid arthritis (RA; n = 328) completed an online cross-sectional survey. Patients reported demographic and clinical/patient characteristics and the amount of arthritis medication information received from 15 information sources. Bivariate and multivariate linear regression analyses were used to investigate whether those characteristics were associated with the amount of medication information patients received. Arthritis patients received the most information from health professionals, followed by printed materials, media sources, and interpersonal sources. Greater receipt of information was associated with greater medication adherence, taking more medications, greater medication-taking concerns, more satisfaction with doctor medication-related support, and Black compared to White race. RA patients reported receiving more information compared to OA patients, and differences were found between RA patients and OA patients in characteristics associated with more information receipt. In conclusion, arthritis patients received the most medication information from professional sources, and both positive (e.g., greater satisfaction with doctor support) and negative (e.g., more medication-taking concerns) characteristics were associated with receiving more medication information.

    Full Text Available For a long time, the African continent was regarded as the ‘Dark Continent’. The rapid assimilation of information technologies into the African economies has placed Africa firmly on a trajectory that will see it compete and integrate with the developed world. As nations and organisations become more information-centric, it is natural that conflicts and competition amongst the various nations or organisations will become increasingly information-based. In this article, the authors reflect upon information-based conflict in Africa. Areas of information conflict that are discussed include censorship, communications intercepts, the use of information and communications to instigate violence and uprisings, and the possibility of cyberwarfare. The article shows that the use of technology to conduct information conflict in Africa is prevalent, and that it is likely to increase.

  16. Information-time based futures pricing (United States)

    Yen, Simon; Wang, Jai Jen


    This study follows Clark [P.K. Clark, A subordinated stochastic process model with finite variance for speculative prices, Econometrica 41 (1973) 135-155] and Chang, Chang and Lim [C.W. Chang, S.K. Chang, K.G. Lim, Information-time option pricing: Theory and empirical evidence, Journal of Financial Economics 48 (1998) 211-242] to subordinate an information-time based directing process into calendar-time based parent processes. A closed-form futures pricing formula is derived after taking into account the information-time setting and the stochasticity of the spot price, interest rate, and convenience yield. According to the empirical results on the TAIEX and TFETX data from 1998/7/21 to 2003/12/31, the information-time based model performs better than its calendar-time based counterpart and the cost of carry model, especially when the information arrival intensity estimates become larger.

  17. [Legal implications of information to the patient in nuclear medicine]. (United States)

    Fernández Sánchez, J


    Every patient has the right to be informed about a medical procedure. The nuclear medicine physician has the duty to inform the patients and, if necessary, to obtain a reasonable written consent before some radioisotopic examinations. The following must be considered in every informed consent of a nuclear medicine procedure: the need for the patient information ("why"), the type of information given ("how"), the person who performs it ("who"), the moment in the time ("when") and the place ("where") where the consent is performed. It must always be kept in mind that, although the informed consent has a protection function from the medicolegal point of view, this function may be lost if the consent is not performed correctly. In this paper the importance and the medicolegal implications of the patient information in Nuclear Medicine are evaluated and discussed.

(United States)

    Miller, R A; Gardner, R M


    In mid-1996, the FDA called for discussions on regulation of clinical software programs as medical devices. In response, a consortium of organizations dedicated to improving health care through information technology has developed recommendations for the responsible regulation and monitoring of clinical software systems by users, vendors, and regulatory agencies. Organizations assisting in development of recommendations, or endorsing the consortium position include the American Medical Informatics Association, the Computer-based Patient Record Institute, the Medical Library Association, the Association of Academic Health Sciences Libraries, the American Health Information Management Association, the American Nurses Association, the Center for Healthcare Information Management, and the American College of Physicians. The consortium proposes four categories of clinical system risks and four classes of measured monitoring and regulatory actions that can be applied strategically based on the level of risk in a given setting. The consortium recommends local oversight of clinical software systems, and adoption by healthcare information system developers of a code of good business practices. Budgetary and other constraints limit the type and number of systems that the FDA can regulate effectively. FDA regulation should exempt most clinical software systems and focus on those systems posing highest clinical risk, with limited opportunities for competent human intervention.

  19. The Impact of Information Culture on Patient Safety Outcomes (United States)

    Mikkonen, Santtu; Saranto, Kaija; Bates, David W.


    Summary Background An organization’s information culture and information management practices create conditions for processing patient information in hospitals. Information management incidents are failures that could lead to adverse events for the patient if they are not detected. Objectives To test a theoretical model that links information culture in acute care hospitals to information management incidents and patient safety outcomes. Methods Reason’s model for the stages of development of organizational accidents was applied. Study data were collected from a cross-sectional survey of 909 RNs who work in medical or surgical units at 32 acute care hospitals in Finland. Structural equation modeling was used to assess how well the hypothesized model fit the study data. Results Fit indices indicated a good fit for the model. In total, 18 of the 32 paths tested were statistically significant. Documentation errors had the strongest total effect on patient safety outcomes. Organizational guidance positively affected information availability and utilization of electronic patient records, whereas the latter had the strongest total effect on the reduction of information delays. Conclusions Patient safety outcomes are associated with information management incidents and information culture. Further, the dimensions of the information culture create work conditions that generate errors in hospitals.

    Patient satisfaction is an important tool of evaluating medical services quality and improving the work of hospital. Patient satisfaction evaluation information system is an extremely important aspect of hospital informationization. However, satisfaction itself is a complex concept, involving much uncertainty. To make the patient satisfaction evaluation information more objective and real, this paper designed patient satisfaction information evaluation system based on grey fuzzy theory and introduced the structure, function and mathematical theory adopted by the system. The system constructed comprehensive evaluation model combining grey correlation method and fuzzy theory, assessed satisfaction using multi-level fuzzy comprehensive evaluation method and adopted equal time interval GM (1,1)model for grey system forecasting.%病人满意度是评价医院服务质量、改进医院工作的重要工具之一,因此,病人满意度测评信息系统就成为医院信息化一个非常重要的方面.但满意度本身存在很多不确定性,为使测评结果更趋于客观和真实,基于灰色模糊理论设计了病人满意度测评信息系统,并介绍了系统的结构、主要功能和采用的数学理论.系统结合灰色关联方法和模糊理论建立综合评价模型,用多层次模糊综合评判方法进行满意度评价,采用等时距EGM(1,1)模型进行灰色系统预测.

  1. OPIC: Ontology-driven Patient Information Capturing system for epilepsy. (United States)

    Sahoo, Satya S; Zhao, Meng; Luo, Lingyun; Bozorgi, Alireza; Gupta, Deepak; Lhatoo, Samden D; Zhang, Guo-Qiang


    The widespread use of paper or document-based forms for capturing patient information in various clinical settings, for example in epilepsy centers, is a critical barrier for large-scale, multi-center research studies that require interoperable, consistent, and error-free data collection. This challenge can be addressed by a web-accessible and flexible patient data capture system that is supported by a common terminological system to facilitate data re-usability, sharing, and integration. We present OPIC, an Ontology-driven Patient Information Capture (OPIC) system that uses a domain-specific epilepsy and seizure ontology (EpSO) to (1) support structured entry of multi-modal epilepsy data, (2) proactively ensure quality of data through use of ontology terms in drop-down menus, and (3) identify and index clinically relevant ontology terms in free-text fields to improve accuracy of subsequent analytical queries (e.g. cohort identification). EpSO, modeled using the Web Ontology Language (OWL), conforms to the recommendations of the International League Against Epilepsy (ILAE) classification and terminological commission. OPIC has been developed using agile software engineering methodology for rapid development cycles in close collaboration with domain expert and end users. We report the result from the initial deployment of OPIC at the University Hospitals Case Medical Center (UH CMC) epilepsy monitoring unit (EMU) as part of the NIH-funded project on Sudden Unexpected Death in Epilepsy (SUDEP). Preliminary user evaluation shows that OPIC has achieved its design objectives to be an intuitive patient information capturing system that also reduces the potential for data entry errors and variability in use of epilepsy terms.

  2. Patient autonomy and relatives' right to know genetic information. (United States)

    Gilbar, Roy


    One of the most difficult issues doctors face is a conflict between their professional duties. Such a conflict may arise when doctors know that information has implications not only for patients but also for family members but their duty of confidentiality prevents them from disclosing it. A comparative analysis of English and Israeli medical law reveals that the doctors' duty is based on two principles: a liberal perception of patient autonomy and an overriding utilitarian principle of prevention of harm. However, socio-medical research indicates that these principles do not entirely reflect the views of patients and doctors and are too narrow to deal with the complex situations in practice. Thus, it is argued that the doctor's legal duty of confidentiality should be reconsidered and qualified when it concerns the family. It is suggested that if medical law seeks to recognize the various interests family members have in genetic information then we should consider a different approach, founded on a relational interpretation of autonomy and communitarian notions of solidarity and moral responsibility. This approach perceives confidentiality and privacy as embracing the family unit, based on the view that close relatives are not entirely outside the private sphere of the individual but rather are integral to his or her identity. Thus, to the utilitarian mechanism available in medical law this approach adds a social criterion: The effect any decision (to disclose or not to disclose) will have on the familial relationship and on the dynamics of the particular family. This will provide a more flexible and workable alternative for doctors to resolve familial tensions over access to genetic information.

  5. Information needs and information-seeking preferences of ALS patients and their carers. (United States)

    Abdulla, Susanne; Vielhaber, Stefan; Machts, Judith; Heinze, Hans-Jochen; Dengler, Reinhard; Petri, Susanne


    Our objective was to investigate information-seeking behaviour in patients with ALS and their caregivers and their rating of the usefulness of different information sources in Germany. Surveys were made on 106 patients and 100 caregivers in two university ALS outpatient clinics. Before seeing a doctor, 28% of patients and 23% of caregivers had used other sources to find symptom related information, mostly the internet. Although two-thirds were satisfied with the means of diagnosis disclosure, 88% of patients and 85% of caregivers searched for additional information, most often the internet (patients 72%, caregivers 85%), followed by patient brochures (patients 58%, caregivers 66%). Internet, patient brochures and the 'German Neuromuscular Disease Society' were rated most frequently as useful/very useful. Traditional print media and interpersonal contacts were also frequently used and most respondents relied on more than one source for information. Only few respondents used the internet for exchange with other patients. Two-thirds wanted to discuss web contents with their physician. In conclusion, patients with ALS and their caregivers clearly have additional information needs. Besides traditional information sources, the internet is frequently used. Therefore, reliable and useful websites should be provided. Patients' and caregivers' need to discuss their findings with the physician should be acknowledged.

  12. Matchmaking Semantic Based for Information System Interoperability

    CERN Document Server

    Wicaksana, I Wayan Simri


    Unlike the traditional model of information pull, matchmaking is base on a cooperative partnership between information providers and consumers, assisted by an intelligent facilitator (the matchmaker). Refer to some experiments, the matchmaking to be most useful in two different ways: locating information sources or services that appear dynamically and notification of information changes. Effective information and services sharing in distributed such as P2P based environments raises many challenges, including discovery and localization of resources, exchange over heterogeneous sources, and query processing. One traditional approach for dealing with some of the above challenges is to create unified integrated schemas or services to combine the heterogeneous sources. This approach does not scale well when applied in dynamic distributed environments and has many drawbacks related to the large numbers of sources. The main issues in matchmaking are how to represent advertising and request, and how to calculate poss...

    Dietrich, Martin; Renner, Simone


    This study analyzes the impact of subjective quality information in the form of aggregate patient experience outcomes on respondent evaluation and intended choice of hospitals. We compared clinical performance-based quality measures (i.e., wound infection rates) with participant evaluations and choice intentions when they were additionally provided with subjective quality information (i.e., patient experience outcomes in different display formats). Results suggest that patient experience outcomes significantly affected the evaluations and choice intentions. Additionally, we found significant effects of subjective information display formats. Limitations, directions for future research, and implications for publishing subjective quality information in health care markets are discussed.

    Jensen, Matilde Nisbeth; Zethsen, Karen Korning

    This paper seeks to empirically explore the claim that translated Danish Patient Information Leaflets (PILs) are less lay-friendly than their English source texts. The last two decades have seen an increased focus on providing patients with lay-friendly, easily understood information, enabling them...... to make informed decisions concerning their health. For this purpose, many new genres have been created, one such genre being the PIL, a mandatory text which in an EU context has to accompany all medication informing patients about dosage, side effects etc. Legally, the PIL genre is required to ensure lay......-friendliness between the original PIL and the Danish version could be a reconsideration of the current EU legislation that only the English original must be user-tested to ensure lay-friendliness. Key words: Corpus analysis, expert-lay communication, lay-friendliness, Patient Information Leaflets, translation...

  19. Information security requirements in patient-centred healthcare support systems. (United States)

    Alsalamah, Shada; Gray, W Alex; Hilton, Jeremy; Alsalamah, Hessah


    Enabling Patient-Centred (PC) care in modern healthcare requires the flow of medical information with the patient between different healthcare providers as they follow the patient's treatment plan. However, PC care threatens the stability of the balance of information security in the support systems since legacy systems fall short of attaining a security balance when sharing their information due to compromises made between its availability, integrity, and confidentiality. Results show that the main reason for this is that information security implementation in discrete legacy systems focused mainly on information confidentiality and integrity leaving availability a challenge in collaboration. Through an empirical study using domain analysis, observations, and interviews, this paper identifies a need for six information security requirements in legacy systems to cope with this situation in order to attain the security balance in systems supporting PC care implementation in modern healthcare.

  20. Web information retrieval based on ontology (United States)

    Zhang, Jian


    The purpose of the Information Retrieval (IR) is to find a set of documents that are relevant for a specific information need of a user. Traditional Information Retrieval model commonly used in commercial search engine is based on keyword indexing system and Boolean logic queries. One big drawback of traditional information retrieval is that they typically retrieve information without an explicitly defined domain of interest to the users so that a lot of no relevance information returns to users, which burden the user to pick up useful answer from these no relevance results. In order to tackle this issue, many semantic web information retrieval models have been proposed recently. The main advantage of Semantic Web is to enhance search mechanisms with the use of Ontology's mechanisms. In this paper, we present our approach to personalize web search engine based on ontology. In addition, key techniques are also discussed in our paper. Compared to previous research, our works concentrate on the semantic similarity and the whole process including query submission and information annotation.

  2. The role of patient-clinician information engagement and information seeking from nonmedical channels in fruit and vegetable intake among cancer patients. (United States)

    Moldovan-Johnson, Mihaela; Martinez, Lourdes; Lewis, Nehama; Freres, Derek; Hornik, Robert C


    Previous research suggests positive effects of health information seeking on prevention behaviors such as diet, exercise, and fruit and vegetable consumption. The present study builds upon this research and strengthens causal claims from it by examining the lagged effect of patient-clinician information engagement on fruit and vegetable consumption as well as the indirect effect on the outcome through seeking information from nonmedical channels. The results are based on data collected from a randomly drawn sample of breast, prostate, and colorectal cancer patients from the Pennsylvania Cancer Registry who completed mail surveys in the Fall of 2006 and 2007. There was a 65% response rate for baseline subjects (resulting n = 2,013); of those, 1,293 were interviewed 1 year later, and 1,257 were available for our analyses. Results show a positive lagged main effect of patient-clinician information engagement at baseline on fruit and vegetable consumption at follow-up (B = 0.26, SE = 0.10, p = .01). The mediation analysis shows that patient-clinician information engagement leads to increased fruit and vegetable consumption among cancer patients, in part through patients' information seeking from nonmedical channels. Implications of these findings for the cancer patient population and for physicians are discussed.

    Callen, Joanne


    Electronic health records and the Internet will continue to transform how information is accessed and shared. Users of health data such as health professionals, governments, policymakers, researchers and patients themselves need to be able to access the right information at the right time and be confident in the quality of that information, whether personal, aggregated or knowledge based. It is essential to evaluate information systems and applications that claim to improve information quality and access in order to provide evidence that they support healthcare delivery and improve patient outcomes.

  5. Implementing AORN recommended practices for transfer of patient care information. (United States)

    Seifert, Patricia C


    The Joint Commission estimates that 80% of serious medical errors are associated with miscommunication during patient transfers. Patient transfers may occur between a wide array of settings: between physicians' offices or preoperative areas and traditional ORs or ambulatory settings, between emergency departments or interventional suites and the OR, and between other areas where the exchange of patient information occurs. AORN's "Recommended practices for transfer of patient care information" serves as a guide for establishing achievable practices that promote a safe level of care during perioperative patient transfers. Strategies for the successful implementation of the recommended practices include promoting teamwork, including with the patient and the patient's family members; developing effective communication skills; documenting processes; creating and adhering to policies and procedures; and establishing quality management programs.

    J. Mannar Mannan


    Full Text Available Information Searching and retrieval is a challenging task in the traditional keyword based textual information retrieval system. In the growing information age, adding huge data every day the searching problem also augmented. Keyword based retrieval system returns bulk of junk document irrelevant to query. To address the limitations, this paper proposed query terms along with semantic terms for information retrieval using multiple ontology reference. User query sometimes reflects multiple domain of interest that persist us to collect semantically related ontologies. If no related ontology exists then WordNet ontology used to retrieve semantic terms related to query term. In this approach, classes on the ontology derived as semantic related text keywords, these keywords considered for rank the documents.

    JINGXiaojun; LIUYulin; XIONGYuqing


    An image filtering based on improved information entropy is proposed in this paper, which can overcome the shortcomings of hybrid linear and non-linear filtering algorithm. Due to the shortcomings of information entropy in the field of data fusion, we introduce the consistency constraint factor of sub-source report and subsource performance difference parameter, propose the concept of fusion entropy, utilize its amendment and regularity function on sub-source decision-making matrix, bring into play the competency, redundency and complementarity of information fusion, suppress and delete fault and invalid information, strengthen and preserve correct and useful information, overcome the risk of error reporting on single source critical point and the shortcomings of reliability and error tolerating, add the decision-making criteria of multiple sub-source fusion, finally improve filtering quality. Subsequent experiments show its validity and improved filtering performance, thus providing a new way of image filtering technique.

  8. Improving information for community-based adaptation

    Energy Technology Data Exchange (ETDEWEB)

    Huq, Saleemul


    Community-based adaptation aims to empower local people to cope with and plan for the impacts of climate change. In a world where knowledge equals power, you could be forgiven for thinking that enabling this type of adaptation boils down to providing local people with information. Conventional approaches to planning adaptation rely on 'expert' advice and credible 'science' from authoritative information providers such as the Intergovernmental Panel on Climate Change. But to truly support the needs of local communities, this information needs to be more site-specific, more user-friendly and more inclusive of traditional knowledge and existing coping practices.

    Aureliu Zgureanu


    Full Text Available An information encryption system based on Boolean functions is proposed. Information processing is done using multidimensional matrices, performing logical operations with these matrices. At the basis of ensuring high level security of the system the complexity of solving the problem of building systems of Boolean functions that depend on many variables (tens and hundreds is set. Such systems represent the private key. It varies both during the encryption and decryption of information, and during the transition from one message to another.

  10. Parallel Patient Karyotype Information System using Multi-threads

    Directory of Open Access Journals (Sweden)



    Full Text Available Human cytogenetic data are the typical laboratory results from hospitals. Karyogram is used to show the chromosome characteristics. The characteristics are written as karyotype strings. For a particular patient, there may be many records of karyotype strings due to several visits. These data for many patients are increasingly large and must be stored properly for further investigation and analysis. This research introduces the information system for the hospital for keeping the karyotypes of patients and applies the parallel method for searching required karyotypes, extracting related patient information. Particularly, we exploit the technology of Node.js with multithreads while splitting queries to search in parallel. The search method is integrated to the cytogenetic information system which is aimed to use for studying karyotypes of leukemia patients.

    Christmann, Elli; Holle, Regina; Schüssler, Dörte; Beier, Jutta; Dassen, Theo


    The article represents results of a theoretical work in the field of nursing education, with the topic: Verbal Patient Information through Nurses--A Case of Stroke Patients. The literature review and analysis show that there is a shortage in (stroke) patient information generally and a lack of successful concepts and strategies for the verbal (stroke) patient information through nurses in hospitals. The authors have developed a theoretical basis for health information as a nursing intervention and this represents a model of health information as a "communicational teach-and-learn process", which is of general application to all patients. The health information takes place as a separate nursing intervention within a non-public, face-to-face communication situation and in the steps-model of the nursing process. Health information is seen as a learning process for patients and nurses too. We consider learning as information production (constructivism) and information processing (cognitivism). Both processes are influenced by different factors and the illness-situation of patients, personality information content and the environment. For a successful health information output, it is necessary to take care of these aspects and this can be realized through a constructivational understanding of didactics. There is a need for an evaluation study to prove our concept of health information.

  14. Information and shared decision-making are top patients' priorities

    Directory of Open Access Journals (Sweden)

    Bronstein Alexander


    Full Text Available Abstract Background The profound changes in medical care and the recent stress on a patient-centered approach mandate evaluation of current patient priorities. Methods Hospitalized and ambulatory patients at an academic medical center in central Israel were investigated. Consecutive patients (n = 274 indicated their first and second priority for a change or improvement in their medical care out of a mixed shortlist of 6 issues, 3 related to patient-physician relationship (being better informed and taking part in decisions; being seen by the same doctor each time; a longer consultation time and 3 issues related to the organizational aspect of care (easier access to specialists/hospital; shorter queue for tests; less charges for drugs. Results Getting more information from the physician and taking part in decisions was the most desirable patient choice, selected by 27.4% as their first priority. The next choices – access and queue – also relate to more patient autonomy and control over that of managed care regulations. Patients studied were least interested in continuity of care, consultation time or cost of drugs. Demographic or clinical variables were not significantly related to patients' choices. Conclusion Beyond its many benefits, being informed by their doctor and shared decision making is a top patient priority.

  16. Security of healthcare information systems based on the CORBA middleware. (United States)

    Blobel, B; Holena, M


    The development of healthcare systems in accordance to the "Shared Care" paradigm results in co-operative health information systems across the boundaries of organisational, technological, and policy domains. Increasingly, these distributed and heterogeneous systems are based on middleware approaches, such as CORBA. Regarding the sensitivity of personal and medical data, such open, distributed, and heterogeneous health information systems demand a high level of data protection and data security, both with respect to patient information and with respect to users. The security concepts and measures available and additionally needed in health information systems based on CORBA architecture are described in this paper. The proposed security solution is also open to other middleware approaches, such as DHE or HL7.

  18. Managing the unmet psychosocial and information needs of patients with cancer

    Directory of Open Access Journals (Sweden)

    Kathleen Abrahamson


    Full Text Available Kathleen Abrahamson1, Morgan Durham1, Rebekah Fox21Department of Public Health, Western Kentucky University, Bowling Green, KY, USA; 2Department of Communication, Texas State University, San Marcos, TX, USAAbstract: In this article, we synthesize current literature regarding the unmet needs of cancer patients, with a specific focus on interventions that address psychosocial distress, social support, and information deficits. Research indicates many patients diagnosed with cancer express unmet needs in terms of emotional distress, decision-making support, and practical concerns such as childcare, transportation, and financial assistance. Four types of system-level barriers to the meeting of patient psychosocial and information-based needs emerge from the literature: underidentification of needs due to inadequate assessment, time constraints on cancer care providers, lack of adequate reimbursement for psychosocial and information services, and barriers related to communication of disease-related information. There is also evidence that unmet need, especially unmet information need, is related to the level of patient health literacy. Patient empowerment through the resolution of unmet needs increases patient participation in care, and is especially crucial in regards to understanding risks and benefits of treatment. There is evidence that some interventions are effective for some patients, and that even relatively simple interventions can reduce psychosocial and information-based needs. The challenge is therefore to discover which intervention will be effective for each individual patient, and to attain the skills and resources necessary to intervene appropriately.Keywords: cancer, unmet need, health literacy, intervention

  1. Cardiovascular implantable electronic devices: patient education, information and ethical issues. (United States)

    Manaouil, Cécile; Gignon, Maxime; Traulle, Sarah


    Cardiovascular implantable electronic devices (CIED) are implanted increasingly frequently. CIEDs are indicated for the treatment of bradycardia, tachycardia and heart failure and therefore improve quality of life and life expectancy. CIED can treat ventricular arrhythmias that would be fatal without immediate care. However, CIEDs raise several patient education, medico-legal, and ethical questions that will be addressed in this article. Information is a patient's right, and necessary for informed consent. When implanting a CIED, the patient must be educated about the need for the device, the function of the device, any restrictions that apply postimplant, and postimplant follow-up methods and schedules. This transfer of information to the patient makes the patient responsible. The occupational physician can determine whether a patient wearing a CIED is able to work. Under current French law, patients are not prohibited from working while wearing a CIED. However, access to certain job categories remains limited, such as jobs involving mechanical stress to the chest, exposure to electromagnetic fields, or jobs requiring permanent vigilance. Pacemakers and defibrillators are medical treatments and are subject to the same ethical and clinical considerations as any other treatment. However, stopping a pacemaker or a defibrillator raises different ethical issues. Implantable Cardioverter Defibrillator shocks can be considered to be equivalent to resuscitation efforts and can be interpreted as being unreasonable in an end-of-life patient. Pacing is painless and it is unlikely to unnecessarily prolong the life of a patient with a terminal disease. Patients with a CIED should live as normally as possible, but must also be informed about the constraints related to the device and must inform each caregiver about the presence of the device. The forensic and ethical implications must be assessed in relation to current legislation.

  2. [Patient information: management in the beginning of the XXIth century]. (United States)

    Rougé-Maillart, C; Tuech, J J; Pessaux, P; Riche, P; Penneau, M


    The Conseil d'Etat, the supreme jurisdiction on legislative matters in France, rendered its decree on January 5, 2000, founding its decision on jurisprudence established in 1997 and 1998 by the supreme Court of Appeals. In accordance with this decision, physicians have a legal obligation to inform patients of all possible risks, including very exceptional risks. The information may be given to the patient in any appropriate form. Proof that information was delivered to the patient is incumbent upon the physician. When proof of information delivery is provided, any injury compensation can only be awarded on the grounds of ill-fate. We conducted an objective review of the jurisprudence on patient information and report the three basic aspects observed in the current situation in France. In application of the Court of Appeals judgments of February 25, 1997 and October 14, 1997, proof of delivery of information to the patient is incumbent upon the physician. The question is whether the physician must retain written documents as necessary proof against future claims. The answer to this question is not straightforward. A written document is not the only proof accepted by the court and could even be of debatable legal value if used inappropriately. The solution retained by the Conseil d'Etat is a good example. The real debate concerns the information content. It now appears that the physician is required to inform his/her patient of all risks susceptible of influencing the patient's decision, particularly serious or life-threatening risks, but also, and most certainly, risks that in the past have been considered frequent but benign. Finally, the judges recall that failure to provide information does not in itself assert the physician's civil responsibility, proof of real damage is also needed. But the reality of damage (ill-fate) depends on the reality of the choice open to the patient had he/she been informed. And the true nature of the choice open to the patient is

  3. Sensor management based on fisher information gain

    Institute of Scientific and Technical Information of China (English)

    Tian Kangsheng; Zhu Guangxi


    Multi-sensor system is becoming increasingly important in a variety of military and civilian applications. In general, single sensor system can only provide partial information about environment while multi-sensor system provides a synergistic effect, which improves the quality and availability of information. Data fusion techniques can effectively combine this environmental information from similar and/or dissimilar sensors. Sensor management, aiming at improving data fusion performance by controlling sensor behavior, plays an important role in a data fusion process. This paper presents a method using fisher information gain based sensor effectiveness metric for sensor assignment in multi-sensor and multi-target tracking applications. The fisher information gain is computed for every sensor-target pairing on each scan. The advantage for this metric over other ones is that the fisher information gain for the target obtained by multi-sensors is equal to the sum of ones obtained by the individual sensor, so standard transportation problem formulation can be used to solve this problem without importing the concept of pseudo sensor. The simulation results show the effectiveness of the method.

  4. Spatial information semantic query based on SPARQL (United States)

    Xiao, Zhifeng; Huang, Lei; Zhai, Xiaofang


    How can the efficiency of spatial information inquiries be enhanced in today's fast-growing information age? We are rich in geospatial data but poor in up-to-date geospatial information and knowledge that are ready to be accessed by public users. This paper adopts an approach for querying spatial semantic by building an Web Ontology language(OWL) format ontology and introducing SPARQL Protocol and RDF Query Language(SPARQL) to search spatial semantic relations. It is important to establish spatial semantics that support for effective spatial reasoning for performing semantic query. Compared to earlier keyword-based and information retrieval techniques that rely on syntax, we use semantic approaches in our spatial queries system. Semantic approaches need to be developed by ontology, so we use OWL to describe spatial information extracted by the large-scale map of Wuhan. Spatial information expressed by ontology with formal semantics is available to machines for processing and to people for understanding. The approach is illustrated by introducing a case study for using SPARQL to query geo-spatial ontology instances of Wuhan. The paper shows that making use of SPARQL to search OWL ontology instances can ensure the result's accuracy and applicability. The result also indicates constructing a geo-spatial semantic query system has positive efforts on forming spatial query and retrieval.

    Sankarasubramanian, Jagadesan; Vishnu, Udayakumar S; Khader, L K M Abdul; Sridhar, Jayavel; Gunasekaran, Paramasamy; Rajendhran, Jeyaprakash


    Brucella sp. causes a major zoonotic disease, brucellosis. Brucella belongs to the family Brucellaceae under the order Rhizobiales of Alphaproteobacteria. We present BrucellaBase, a web-based platform, providing features of a genome database together with unique analysis tools. We have developed a web version of the multilocus sequence typing (MLST) (Whatmore et al., 2007) and phylogenetic analysis of Brucella spp. BrucellaBase currently contains genome data of 510 Brucella strains along with the user interfaces for BLAST, VFDB, CARD, pairwise genome alignment and MLST typing. Availability of these tools will enable the researchers interested in Brucella to get meaningful information from Brucella genome sequences. BrucellaBase will regularly be updated with new genome sequences, new features along with improvements in genome annotations. BrucellaBase is available online at or

  9. The ethics of physicians' web searches for patients' information. (United States)

    Genes, Nicholas; Appel, Jacob


    When physicians search the web for personal information about their patients, others have argued that this undermines patients' trust, and the physician-patient relationship in general. We add that this practice also places other relationships at risk, and could jeopardize a physician's career. Yet there are also reports of web searches that have unambiguously helped in the care of patients, suggesting circumstances in which a routine search of the web could be beneficial. We advance the notion that, just as nonverbal cues and unsolicited information can be useful in clinical decision making, so too can online information from patients. As electronic records grow more voluminous and span more types of data, searching these resources will become a clinical skill, to be used judiciously and with care--just as evaluating the literature is, today. But to proscribe web searches of patients' information altogether is as nonsensical as disregarding findings from physical exams-instead, what's needed are guidelines for when to look and how to evaluate what's uncovered, online.

  11. Systematic Review of Quality of Patient Information on Liposuction in the Internet (United States)

    Zuk, Grzegorz; Eylert, Gertraud; Raptis, Dimitri Aristotle; Guggenheim, Merlin; Shafighi, Maziar


    Background: A large number of patients who are interested in esthetic surgery actively search the Internet, which represents nowadays the first source of information. However, the quality of information available in the Internet on liposuction is currently unknown. The aim of this study was to assess the quality of patient information on liposuction available in the Internet. Methods: The quantitative and qualitative assessment of Web sites was based on a modified Ensuring Quality Information for Patients tool (36 items). Five hundred Web sites were identified by the most popular web search engines. Results: Two hundred forty-five Web sites were assessed after duplicates and irrelevant sources were excluded. Only 72 (29%) Web sites addressed >16 items, and scores tended to be higher for professional societies, portals, patient groups, health departments, and academic centers than for Web sites developed by physicians, respectively. The Ensuring Quality Information for Patients score achieved by Web sites ranged between 8 and 29 of total 36 points, with a median value of 16 points (interquartile range, 14–18). The top 10 Web sites with the highest scores were identified. Conclusions: The quality of patient information on liposuction available in the Internet is poor, and existing Web sites show substantial shortcomings. There is an urgent need for improvement in offering superior quality information on liposuction for patients intending to undergo this procedure. PMID:27482498

  12. Heterogeneous information-based artificial stock market (United States)

    Pastore, S.; Ponta, L.; Cincotti, S.


    In this paper, an information-based artificial stock market is considered. The market is populated by heterogeneous agents that are seen as nodes of a sparsely connected graph. Agents trade a risky asset in exchange for cash. Besides the amount of cash and assets owned, each agent is characterized by a sentiment. Moreover, agents share their sentiments by means of interactions that are identified by the graph. Interactions are unidirectional and are supplied with heterogeneous weights. The agent's trading decision is based on sentiment and, consequently, the stock price process depends on the propagation of information among the interacting agents, on budget constraints and on market feedback. A central market maker (clearing house mechanism) determines the price process at the intersection of the demand and supply curves. Both closed- and open-market conditions are considered. The results point out the validity of the proposed model of information exchange among agents and are helpful for understanding the role of information in real markets. Under closed market conditions, the interaction among agents' sentiments yields a price process that reproduces the main stylized facts of real markets, e.g. the fat tails of the returns distributions and the clustering of volatility. Within open-market conditions, i.e. with an external cash inflow that results in asset price inflation, also the unitary root stylized fact is reproduced by the artificial stock market. Finally, the effects of model parameters on the properties of the artificial stock market are also addressed.

  13. Giving information to family members of patients in the intensive care unit: Iranian nurses' ethical approaches. (United States)

    Farahani, Mansoureh A; Gaeeni, Mina; Mohammadi, Nooreddin; Seyedfatemi, Naima


    Receiving information related to patients hospitalized in the intensive care unit is among the most important needs of the family members of such patients. When health care professionals should decide whether to be honest or to give hope, giving information becomes an ethical challenge We conducted a research to study the ethical approaches of Iranian nurses to giving information to the family members of patients in the intensive care units. This research was conducted in the intensive care units of three teaching hospitals in Iran. It employed a qualitative approach involving semi-structured and in-depth interviews with a purposive sample of 12 nurses to identify the ethical approaches to giving information to family members of the intensive care unit patients. A conventional content analysis of the data produced two categories and five subcategories. The two categories were as follows: a) informational support, and b) emotional support. Informational support had 2 subcategories consisting of being honest in giving information, and providing complete and understandable information. Emotional support in giving information had 3 sub-categories consisting of gradual revelation, empathy and assurance. Findings of the study indicated that ethical approaches to giving information can be in the form of either informational support or emotional support, based on patients' conditions and prognoses, their families' emotional state, the necessity of providing a calm atmosphere in the ICU and the hospital, and other patients and their families' peace. Findings of the present study can be used as a basis for further studies and for offering ethical guidelines in giving information to the families of patients hospitalized in the ICU.

  14. Balancing the presentation of information and options in patient decision aids: an updated review


    Abhyankar, P.; Volk, R.J.; Blumenthal-Barby, J.; Bravo, P.; A. Buchholz; Ozanne, E.; Vidal, D.C.; Col, N; Stalmeier, P F M


    Background Standards for patient decision aids require that information and options be presented in a balanced manner; this requirement is based on the argument that balanced presentation is essential to foster informed decision making. If information is presented in an incomplete/non-neutral manner, it can stimulate cognitive biases that can unduly affect individuals’ knowledge, perceptions of risks and benefits, and, ultimately, preferences. However, there is little clarity about what const...

  15. Ontology for cell-based geographic information (United States)

    Zheng, Bin; Huang, Lina; Lu, Xinhai


    Inter-operability is a key notion in geographic information science (GIS) for the sharing of geographic information (GI). That requires a seamless translation among different information sources. Ontology is enrolled in GI discovery to settle the semantic conflicts for its natural language appearance and logical hierarchy structure, which are considered to be able to provide better context for both human understanding and machine cognition in describing the location and relationships in the geographic world. However, for the current, most studies on field ontology are deduced from philosophical theme and not applicable for the raster expression in GIS-which is a kind of field-like phenomenon but does not physically coincide to the general concept of philosophical field (mostly comes from the physics concepts). That's why we specifically discuss the cell-based GI ontology in this paper. The discussion starts at the investigation of the physical characteristics of cell-based raster GI. Then, a unified cell-based GI ontology framework for the recognition of the raster objects is introduced, from which a conceptual interface for the connection of the human epistemology and the computer world so called "endurant-occurrant window" is developed for the better raster GI discovery and sharing.

  16. Information Filtering Based on Users' Negative Opinions (United States)

    Guo, Qiang; Li, Yang; Liu, Jian-Guo


    The process of heat conduction (HC) has recently found application in the information filtering [Zhang et al., Phys. Rev. Lett.99, 154301 (2007)], which is of high diversity but low accuracy. The classical HC model predicts users' potential interested objects based on their interesting objects regardless to the negative opinions. In terms of the users' rating scores, we present an improved user-based HC (UHC) information model by taking into account users' positive and negative opinions. Firstly, the objects rated by users are divided into positive and negative categories, then the predicted interesting and dislike object lists are generated by the UHC model. Finally, the recommendation lists are constructed by filtering out the dislike objects from the interesting lists. By implementing the new model based on nine similarity measures, the experimental results for MovieLens and Netflix datasets show that the new model considering negative opinions could greatly enhance the accuracy, measured by the average ranking score, from 0.049 to 0.036 for Netflix and from 0.1025 to 0.0570 for Movielens dataset, reduced by 26.53% and 44.39%, respectively. Since users prefer to give positive ratings rather than negative ones, the negative opinions contain much more information than the positive ones, the negative opinions, therefore, are very important for understanding users' online collective behaviors and improving the performance of HC model.

  17. Informational Needs of Head and Neck Cancer Patients. (United States)

    Papadakos, Janet; McQuestion, Maurene; Gokhale, Anandita; Damji, Ali; Trang, Aileen; Abdelmutti, Nazek; Ringash, Jolie


    The patient journey with head and neck cancer (HNC) is particularly challenging given the physical and functional impact of the cancer and treatment. The ability to perform activities of daily living can be severely compromised and have a profound impact on psychosocial well-being. These complex and long-lasting effects can affect patient quality of life for months to years and the literature shows that information for HNC patients is often insufficient. This observational cross-sectional study utilized survey methodology to investigate the informational needs of HNC patients and the preferred modalities for delivery. This was done to inform the development of resources for HNC patients. Four hundred fifty surveys were analyzed. The median age was 61 years and 58% of the cohort was born in Canada. Most were Caucasian (72%), Chinese being the next largest ethnicity (12%). A third had less than high school education and most had cancer of the oral cavity (28%) and were in long-term follow-up (41%). Comparison of the percentage of items to which a patient responded "very important" across the six domains shows variation of importance by domain (overall mixed effects regression model p < 0.0001). Additionally, each domain was compared to the medical domain and all had significantly lower mean scores (all p < 0.0001) with the medical domain scoring highest (mean score 64.6). The top preferred education modalities were teaching with a healthcare professional and pamphlets. This study highlights the type of information that HNC patients want and the format they wish to receive it in. The design provides a comprehensive way to consult with patients toward building education that responds to their specific needs.

    Zeng, Dan


    Relevance models in relevance research is the main research issue in information retrieval and information science. Relevance research of information retrieval can be divided into the system-oriented school and the user-oriented schoo1.The evaluation of relevance is closely related to user's experiences, cognitive status and thinking, and includes the interaction of several level. On this basis, a four-dimension model (information resource, representation of user problem time and components) and an interactive model are critically illuminated. A better understanding of the cognitive model, the episode model and the stratified model is of great importance to the interactive model.

  1. Orthognathic surgery: is patient information on the Internet valid? (United States)

    Aldairy, T; Laverick, S; McIntyre, G T


    The aims of this study were to evaluate the quality and reliability of UK websites providing information on orthognathic and jaw surgery to patients. An Internet search engine ( was used to identify websites containing medical information on 'orthognathic surgery' and 'jaw surgery'. Of over 144,000 links for orthognathic surgery and 700,000 for jaw surgery, the first 100 were examined in detail. After excluding discussion groups, news and video feeds, and removing duplicate sites, only 25 relevant websites remained which were then evaluated using the DISCERN instrument ( Through the 16 questions assessing the reliability and quality of the consumer information which are scored from 1 to 5, a relative index of the quality of the information is produced. The maximum score attainable for an excellent website is 80. Of the 25 websites that were scored, DISCERN indicated the majority of websites fell well below the maximum score. The highest score achieved by one of the websites according to the DISCERN tool was 64 of 80 and the lowest score achieved was 21 of 80. The websites achieving maximum and minimum score were Wikipedia and, respectively. By directing patients to validated websites, clinicians can ensure patients find appropriate information; however, further development of websites relating to orthognathic surgery is required. Internet information should be updated on a regular basis to account for improvements in orthodontic and surgical care.

  2. How geographical information systems analysis influences the continuum of patient care. (United States)

    Pliskie, Jennifer; Wallenfang, Laura


    As the vast repository of data about millions of patients grows, the analysis of this information is changing the provider-patient relationship and influencing the continuum of care for broad swaths of the population. At the same time, while population health management moves from a volume-based model to a value-based one and additional patients seek care due to healthcare reform, hospitals and healthcare networks are evaluating their business models and searching for new revenue streams. Utilizing geographical information systems to model and analyze large amounts of data is helping organizations better understand the characteristics of their patient population, demographic and socioeconomic trends, and shifts in the utilization of healthcare. In turn, organizations can more effectively conduct service line planning, strategic business plans, market growth strategies, and human resource planning. Healthcare organizations that use GIS modeling can set themselves apart by making more informed and objective business strategy decisions.

  3. The usefulness and scientific accuracy of private sector Arabic language patient drug information leaflets (United States)

    Sukkari, Sana R.; Al Humaidan, Abdullah S.; Sasich, Larry D.


    Background Inadequate access to useful scientifically accurate patient information is a major cause of the inappropriate use of drugs resulting in serious personal injury and related costs to the health care system. The definition of useful scientifically accurate patient information for prescription drugs was accepted by the US Secretary of the Department of Health and Human Services in 1996 as that derived from or consistent with the US FDA approved professional product label for a drug. Previous quality content studies found that English language patient drug information leaflets distributed by US pharmacies failed to meet minimum criteria defining useful and scientifically accurate information. Method and findings Evaluation forms containing the explicit elements that define useful scientifically accurate information for three drugs with known serious adverse drug reactions were created based on the current US FDA approved professional product labels. The Arabic language patient drug information leaflets for celecoxib, paroxetine, and lamotrigine were obtained locally and evaluated using a methodology similar to that used in previous quality content patient drug information studies in the US. The Arabic leaflets failed to meet the definition of useful scientifically accurate information. The celecoxib leaflet contained 30% of the required information and the paroxetine and lamotrigine leaflets contained 24% and 20%, respectively. There are several limitations to this study. The Arabic leaflets from only one commercial North American vendor were evaluated and the evaluation included a limited number of drugs. A larger study is necessary to be able to generalize these results. Conclusions The study results are consistent with those of previous quality content studies of commercially available English patient drug information leaflets. The results have important implications for patients as access to a reliable source of drug information may prevent harm or limit

    Maier, Uwe; Fotuhi, Parwis; Seele, Anja; Nikolic, Djordje


    In modern patient interprofessional communication is an impor tant factor of good outcome. The aim of this study was to analyse the intercommunication during ward rounds and information passed by patients' documentation on an internal and geriatric medicine ward. Beside frequent interruptions the ward rounds showed a restricted flow of information that is based and targeted on the chief physician Nursing staff felt excluded from the informational flow. Regarding patients' documentation staff complained about lack of information and illegible notes. Availability of written information was found to be problematic. A team-orientated approach could help to improve interprofessional communication in the future. Besides the importance of carefully performed documentation as a reliable form of communication, communicative contribution of the nursing staff has to be upvalued.

  5. Information filtering based on wiki index database

    CERN Document Server

    Smirnov, A V


    In this paper we present a profile-based approach to information filtering by an analysis of the content of text documents. The Wikipedia index database is created and used to automatically generate the user profile from the user document collection. The problem-oriented Wikipedia subcorpora are created (using knowledge extracted from the user profile) for each topic of user interests. The index databases of these subcorpora are applied to filtering information flow (e.g., mails, news). Thus, the analyzed texts are classified into several topics explicitly presented in the user profile. The paper concentrates on the indexing part of the approach. The architecture of an application implementing the Wikipedia indexing is described. The indexing method is evaluated using the Russian and Simple English Wikipedia.

  6. Information-Technology Based Physics Education (United States)

    Kim, J. S.; Lee, K. H.


    Developing countries emphasize expansion of the educated population but demand for quality improvement follows later. Current science education reform is driven in part by post cold war restructuring of the global economy and associated focus on the education of a more scientifically literate society, due to the industrial change from labor-intensive to high-technology type, and the societal change inherent in the present information era. Industry needs employees of broad and flexible background with inter disciplinary training, engineers with better physics training, and well trained physicists. Education researches have proved that active-learning based methods are superior to the traditional methods and the information technology (IT) has lot to offer in this. Use of IT for improving physics education is briefly discussed with prospects for collaboration in the Asia-Pacific region via Asian Physics Education Network (ASPEN), UNESCO University Foundation Course in Physics (UUFCP), etc.

  8. Information sharing in the brain indexes consciousness in noncommunicative patients. (United States)

    King, Jean-Rémi; Sitt, Jacobo D; Faugeras, Frédéric; Rohaut, Benjamin; El Karoui, Imen; Cohen, Laurent; Naccache, Lionel; Dehaene, Stanislas


    Neuronal theories of conscious access tentatively relate conscious perception to the integration and global broadcasting of information across distant cortical and thalamic areas. Experiments contrasting visible and invisible stimuli support this view and suggest that global neuronal communication may be detectable using scalp electroencephalography (EEG). However, whether global information sharing across brain areas also provides a specific signature of conscious state in awake but noncommunicating patients remains an active topic of research. We designed a novel measure termed "weighted symbolic mutual information" (wSMI) and applied it to 181 high-density EEG recordings of awake patients recovering from coma and diagnosed in various states of consciousness. The results demonstrate that this measure of information sharing systematically increases with consciousness state, particularly across distant sites. This effect sharply distinguishes patients in vegetative state (VS), minimally conscious state (MCS), and conscious state (CS) and is observed regardless of etiology and delay since insult. The present findings support distributed theories of conscious processing and open up the possibility of an automatic detection of conscious states, which may be particularly important for the diagnosis of awake but noncommunicating patients.

  9. Secure information transfer based on computing reservoir (United States)

    Szmoski, R. M.; Ferrari, F. A. S.; de S. Pinto, S. E.; Baptista, M. S.; Viana, R. L.


    There is a broad area of research to ensure that information is transmitted securely. Within this scope, chaos-based cryptography takes a prominent role due to its nonlinear properties. Using these properties, we propose a secure mechanism for transmitting data that relies on chaotic networks. We use a nonlinear on-off device to cipher the message, and the transfer entropy to retrieve it. We analyze the system capability for sending messages, and we obtain expressions for the operating time. We demonstrate the system efficiency for a wide range of parameters. We find similarities between our method and the reservoir computing.

  10. Speech Intelligibility Prediction Based on Mutual Information

    DEFF Research Database (Denmark)

    Jensen, Jesper; Taal, Cees H.


    This paper deals with the problem of predicting the average intelligibility of noisy and potentially processed speech signals, as observed by a group of normal hearing listeners. We propose a model which performs this prediction based on the hypothesis that intelligibility is monotonically related...... to the mutual information between critical-band amplitude envelopes of the clean signal and the corresponding noisy/processed signal. The resulting intelligibility predictor turns out to be a simple function of the mean-square error (mse) that arises when estimating a clean critical-band amplitude using...... a minimum mean-square error (mmse) estimator based on the noisy/processed amplitude. The proposed model predicts that speech intelligibility cannot be improved by any processing of noisy critical-band amplitudes. Furthermore, the proposed intelligibility predictor performs well ( ρ > 0.95) in predicting...

  12. Preface: Internet-Based Management Information Systems

    Institute of Scientific and Technical Information of China (English)


    @@ Recent decades have witnessed a paradigm shift in management information systems research from a technology orientation to a combined focus on technology and management. This shift stems from advances in information technology coupled with information technology fusion that brings information technology and businesses together. Information technology fusion is characterized by technology transparency in that information technology is no longer seen as an addition to a product or servicebut an inherent element of the product or service, so it is transparent to the users. Information technology fusion is also characterized by technology pervasiveness in that information technology now deeply penetrates many businesses who now rely on information technology for survival.

  13. Discussing life expectancy with surgical patients: Do patients want to know and how should this information be delivered?

    Directory of Open Access Journals (Sweden)

    MacDonagh Ruaraidh P


    Full Text Available Abstract Background Predicted patient life expectancy (LE and survival probability (SP, based on a patient's medical history, are important components of surgical decision-making and informed consent. The objective of this study was to assess patients' interpretation of and desire to know information relating to LE, in addition to establishing the most effective format for discussion. Methods A cross sectional survey of 120 patients (mean age = 68.7 years, range 50–90 years, recruited from general urological and surgical outpatient clinics in one District General and one Teaching hospital in Southwest England (UK was conducted. Patients were included irrespective of their current diagnosis or associated comorbidity. Hypothetical patient case scenarios were used to assess patients' desire to know LE and SP, in addition to their preferred presentation format. Results 58% of patients expressed a desire to know their LE and SP, if it were possible to calculate, with 36% not wishing to know either. Patients preferred a combination of numerical and pictorial formats in discussing LE and SP, with numerical, verbal and pictorial formats alone least preferred. 71% patients ranked the survival curve as either their first or second most preferred graph, with 76% rating facial figures their least preferred. No statistically significant difference was noted between sexes or educational backgrounds. Conclusion A proportion of patients seem unwilling to discuss their LE and SP. This may relate to their current diagnosis, level of associated comorbidity or degree of understanding. However it is feasible that by providing this information in a range of presentation formats, greater engagement in the shared decision-making process can be encouraged.

  14. Vision Based Geo Navigation Information Retreival

    Directory of Open Access Journals (Sweden)

    Asif Khan


    Full Text Available In order to derive the three-dimensional camera position from the monocular camera vision, a geo-reference database is needed. Floor plan is a ubiquitous geo-reference database that every building refers to it during construction and facility maintenance. Comparing with other popular geo-reference database such as geo-tagged photos, the generation, update and maintenance of floor plan database does not require costly and time consuming survey tasks. In vision based methods, the camera needs special attention. In contrast to other sensors, vision sensors typically yield vast information that needs complex strategies to permit use in real-time and on computationally con-strained platforms. This research work show that map-based visual odometer strategy derived from a state-of-the-art structure-from-motion framework is particularly suitable for locally stable, pose controlled flight. Issues concerning drifts and robustness are analyzed and discussed with respect to the original framework. Additionally, various usage of localization algorithm in view of vision has been proposed here. Though, a noteworthy downside with vision-based algorithms is the absence of robustness. The greater parts of the methodologies are delicate to scene varieties (like season or environment changes because of the way that they utilize the Sum of Squared Differences (SSD. To stop that, we utilize the Mutual Information which is exceptionally vigorous toward global and local scene varieties. On the other hand, dense methodologies are frequently identified with drift drawbacks. Here, attempt to take care of this issue by utilizing geo-referenced pictures. The algorithm of localization has been executed and experimental results are available. Vision sensors possess the potential to extract information about the surrounding environment and determine the locations of features or points of interest. Having mapped out landmarks in an unknown environment, subsequent observations

  16. Partial order similarity based on mutual information

    CERN Document Server

    Tibély, Gergely; Palla, Gergely


    Comparing the ranking of candidates by different voters is an important topic in social and information science with a high relevance from the point of view of practical applications. In general, ties and pairs of incomparable candidates may occur, thus, the alternative rankings are described by partial orders. Various distance measures between partial orders have already been introduced, where zero distance is corresponding to a perfect match between a pair of partial orders, and larger values signal greater differences. Here we take a different approach and propose a similarity measure based on adjusted mutual information. In general, the similarity value of unity is corresponding to exactly matching partial orders, while a low similarity is associated to a pair of independent partial orders. The time complexity of the computation of this similarity measure is $\\mathcal{O}(\\left|{\\mathcal C}\\right|^3)$ in the worst case, and $\\mathcal{O}(\\left|{\\mathcal C}\\right|^2\\ln \\left|{\\mathcal C}\\right|)$ in the typi...

  17. Technology-Assisted Patient Access to Clinical Information: An Evaluation Framework for Blue Button (United States)

    Nazi, Kim M; Luger, Tana M; Amante, Daniel J; Smith, Bridget M; Barker, Anna; Shimada, Stephanie L; Volkman, Julie E; Garvin, Lynn; Simon, Steven R; Houston, Thomas K


    Background Patient access to clinical information represents a means to improve the transparency and delivery of health care as well as interactions between patients and health care providers. We examine the movement toward augmenting patient access to clinical information using technology. Our analysis focuses on “Blue Button,” a tool that many health care organizations are implementing as part of their Web-based patient portals. Objective We present a framework for evaluating the effects that technology-assisted access to clinical information may have on stakeholder experiences, processes of care, and health outcomes. Methods A case study of the United States Department of Veterans Affairs' (VA) efforts to make increasing amounts of clinical information available to patients through Blue Button. Drawing on established collaborative relationships with researchers, clinicians, and operational partners who are engaged in the VA’s ongoing implementation and evaluation efforts related to Blue Button, we assessed existing evidence and organizational practices through key informant interviews, review of documents and other available materials, and an environmental scan of published literature and the websites of other health care organizations. Results Technology-assisted access to clinical information represents a significant advance for VA patients and marks a significant change for the VA as an organization. Evaluations of Blue Button should (1) consider both processes of care and outcomes, (2) clearly define constructs of focus, (3) examine influencing factors related to the patient population and clinical context, and (4) identify potential unintended consequences. Conclusions The proposed framework can serve as a roadmap to guide subsequent research and evaluation of technology-assisted patient access to clinical information. To that end, we offer a series of related recommendations. PMID:24675395

  18. An efficient steganography method for hiding patient confidential information. (United States)

    Al-Dmour, Hayat; Al-Ani, Ahmed; Nguyen, Hung


    This paper deals with the important issue of security and confidentiality of patient information when exchanging or storing medical images. Steganography has recently been viewed as an alternative or complement to cryptography, as existing cryptographic systems are not perfect due to their vulnerability to certain types of attack. We propose in this paper a new steganography algorithm for hiding patient confidential information. It utilizes Pixel Value Differencing (PVD) to identify contrast regions in the image and a Hamming code that embeds 3 secret message bits into 4 bits of the cover image. In order to preserve the content of the region of interest (ROI), the embedding is only performed using the Region of Non-Interest (RONI).

  19. Mutual information-based facial expression recognition (United States)

    Hazar, Mliki; Hammami, Mohamed; Hanêne, Ben-Abdallah


    This paper introduces a novel low-computation discriminative regions representation for expression analysis task. The proposed approach relies on interesting studies in psychology which show that most of the descriptive and responsible regions for facial expression are located around some face parts. The contributions of this work lie in the proposition of new approach which supports automatic facial expression recognition based on automatic regions selection. The regions selection step aims to select the descriptive regions responsible or facial expression and was performed using Mutual Information (MI) technique. For facial feature extraction, we have applied Local Binary Patterns Pattern (LBP) on Gradient image to encode salient micro-patterns of facial expressions. Experimental studies have shown that using discriminative regions provide better results than using the whole face regions whilst reducing features vector dimension.

  20. Implementing security in computer based patient records clinical experiences. (United States)

    Iversen, K R; Heimly, V; Lundgren, T I


    In Norway, organizational changes in hospitals and a stronger focus on patient safety have changed the way of organizing and managing paper based patient records. Hospital-wide patient records tend to replace department based records. Since not only clinicians, but also other non-medical staff have access to the paper records, they also have easy access to all the information which is available on a specific patient; such a system has obvious 'side effects' on privacy and security. Computer based patient records (CPRs) can provide the solution to this apparent paradox if the complex aspects of security, privacy, effectiveness, and user friendliness are focused on jointly from the outset in designing such systems. Clinical experiences in Norway show that it is possible to design patient record systems that provide a very useful tool for clinicians and other health care personnel (HCP) while fully complying with comprehensive security and privacy requirements.

  1. Leveraging information technology to drive improvement in patient satisfaction. (United States)

    Nash, Mary; Pestrue, Justin; Geier, Peter; Sharp, Karen; Helder, Amy; McAlearney, Ann Scheck


    A healthcare organization's commitment to quality and the patient experience requires senior leader involvement in improvement strategies, and accountability for goals. Further, improvement strategies are most effective when driven by data, and in the world of patient satisfaction, evidence is growing that nurse leader rounding and discharge calls are strategic tactics that can improve patient satisfaction. This article describes how The Ohio State University Medical Center (OSUMC) leveraged health information technology (IT) to apply a data-driven strategy execution to improve the patient experience. Specifically, two IT-driven approaches were used: (1) business intelligence reporting tools were used to create a meaningful reporting system including dashboards, scorecards, and tracking reports and (2) an improvement plan was implemented that focused on two high-impact tactics and data to hardwire accountability. Targeted information from the IT systems enabled clinicians and administrators to execute these strategic tactics, and senior leaders to monitor achievement of strategic goals. As a result, OSUMC's inpatient satisfaction scores on the Hospital Consumer Assessment of Healthcare Providers and Systems survey improved from 56% nines and tens in 2006 to 71% in 2009.

  2. C-PHIS: a concept map-based knowledge base framework to develop personal health information systems. (United States)

    Karla, Pramukh R; Gurupur, Varadraj P


    In this paper we describe the development of a Personal Health Information System using a knowledge base developed using concept maps. Here we describe a solution for providing the critical need to develop an information capturing system that helps domain experts in developing a graphical representation of the aforementioned knowledge base which can then be converted to a machine-actable form of information. A prototype application has been developed using this information capturing system that clearly demonstrates the use of the knowledge base framework using concept maps to develop Personal Health Information System for lung cancer patients.

  3. Patient-targeted googling: the ethics of searching online for patient information. (United States)

    Clinton, Brian K; Silverman, Benjamin C; Brendel, David H


    With the growth of the Internet, psychiatrists can now search online for a wide range of information about patients. Psychiatrists face challenges of maintaining professional boundaries with patients in many circumstances, but little consideration has been given to the practice of searching online for information about patients, an act we refer to as patient-targeted Googling (PTG). Psychiatrists are not the only health care providers who can investigate their patients online, but they may be especially likely to engage in PTG because of the unique relationships involved in their clinical practice. Before searching online for a patient, psychiatrists should consider such factors as the intention of searching, the anticipated effect of gaining information online, and its potential value or risk for the treatment. The psychiatrist is obligated to act in a way that respects the patient's best interests and that adheres to professional ethics. In this article, we propose a pragmatic model for considering PTG that focuses on practical results of searches and that aims to minimize the risk of exploiting patients. We describe three cases of PTG, highlighting important ethical dilemmas in multiple practice settings. Each case is discussed from the standpoint of the pragmatic model.

  4. Concept Tree Based Information Retrieval Model

    Directory of Open Access Journals (Sweden)

    Chunyan Yuan


    Full Text Available This paper proposes a novel concept-based query expansion technique named Markov concept tree model (MCTM, discovering term relationship through the concept tree deduced by term markov network. We address two important issues for query expansion: the selection and the weighting of expansion search terms. In contrast to earlier methods, queries are expanded by adding those terms that are most similar to the concept of the query, rather than selecting terms that are similar to a signal query terms. Utilizing Markov network which is constructed according to the co-occurrence information of the terms in collection, it generate concept tree for each original query term, remove the redundant and irrelevant nodes in concept tree, then adjust the weight of original query and the weight of expansion term based on a pruning algorithm. We use this model for query expansion and evaluate the effectiveness of the model by examining the accuracy and robustness of the expansion methods, Compared with the baseline model, the experiments on standard dataset reveal that this method can achieve a better query quality

  5. Adaptive Filter Based on Gradient Information

    Institute of Scientific and Technical Information of China (English)

    JINGXiaojun; LIJiangfeng; YANGYixian


    In this paper, an adaptive smoothing filter algorithm based on gradient information is proposed. The new method solves the problem of conventional filer that can't smooth noise and sharp edge simultaneously. It is based on the iterative convolution of local adaptive template and the original image signal, the template has the property of diffusing anisotropically. In each iteration, the weight coefficients of filter are determined by the gradient function of each pixel, and they vary with the variety of the gradient function, thus reflects the degree of continuity of the gray value. The weight coefficients also depend on one parameter, which controls the amplitude of the breaking point that needs to be preserved during the iteration. This algorithm sharps the edge of image by iterative computation, and after several iterations the image is adaptively smoothed according to the edge blocking. The simulation results demonstrate that this algorithm can perform filtering effectively. It has appropriate computation complexity and is suitable for real-time processing.

A whole system of care is compatible to the technical solutions and organizational framework based on legal rules. The purpose of this study is to present how can we use Information and Communication Technology (ICT) systemic tools in a new model of patient-oriented care, improving the effectiveness of healthcare for patients with chronic diseases. The study material is the long-term process of healthcare for patients with chronic illness. Basing on the knowledge of the whole circumstances of patient's ecosystem and his needs allow us to build a new ICT model of long term care. The method used is construction, modeling and constant improvement the efficient ICT layer for the patient-centered healthcare model. We present a new constructive approach to systemic process how to use ICT for information management in healthcare system for chronic disease patient. The use of ICT tools in the model for chronic disease can improve all aspects of data management and communication, and the effectiveness of long-term complex healthcare. In conclusion: ICT based model of healthcare can be constructed basing on the interactions of ecosystem's functional parts through information feedback and the provision of services and models as well as the knowledge of the patient itself. Systematic approach to the model of long term healthcare assisted functionally by ICT tools and data management methods will increase the effectiveness of patient care and organizational efficiency.

  7. Iterative evaluation of a web-based health information resource. (United States)

    Rosenfeld, Lindsay; Shepherd, Amy; Agunwamba, Amenah A; McCray, Alexa T


    This article presents the research process and methods used to evaluate and improve a web-based health information resource, called "Community Connect to Research," intended for the public. The research process was iterative and involved collaboration with many partners. Two formal evaluations were conducted in 2009 and 2010 using key informant interviews, usability interviews, focus groups, an online survey, and readability and suitability assessment tools. These methods provided users' perspectives on the overall design, content, and literacy demands of the website as well as valuable feedback on their interaction with the website. The authors subsequently redesigned Community Connect to Research, making significant improvements on the basis of what they learned from the evaluation. The second evaluation revealed that the redesign addressed many issues found in the first evaluation and identified additional areas of possible improvement. Overall, both evaluations suggested that participants believed that the website was useful and valuable, indicating that Community Connect to Research is a health information resource that provides patients and families with accessible, relevant, and high-quality information. Regular formal evaluation is an essential tool for effective ongoing enhancement of health information resources meant for the public.

  9. Cloud based emergency health care information service in India. (United States)

    Karthikeyan, N; Sukanesh, R


    A hospital is a health care organization providing patient treatment by expert physicians, surgeons and equipments. A report from a health care accreditation group says that miscommunication between patients and health care providers is the reason for the gap in providing emergency medical care to people in need. In developing countries, illiteracy is the major key root for deaths resulting from uncertain diseases constituting a serious public health problem. Mentally affected, differently abled and unconscious patients can't communicate about their medical history to the medical practitioners. Also, Medical practitioners can't edit or view DICOM images instantly. Our aim is to provide palm vein pattern recognition based medical record retrieval system, using cloud computing for the above mentioned people. Distributed computing technology is coming in the new forms as Grid computing and Cloud computing. These new forms are assured to bring Information Technology (IT) as a service. In this paper, we have described how these new forms of distributed computing will be helpful for modern health care industries. Cloud Computing is germinating its benefit to industrial sectors especially in medical scenarios. In Cloud Computing, IT-related capabilities and resources are provided as services, via the distributed computing on-demand. This paper is concerned with sprouting software as a service (SaaS) by means of Cloud computing with an aim to bring emergency health care sector in an umbrella with physical secured patient records. In framing the emergency healthcare treatment, the crucial thing considered necessary to decide about patients is their previous health conduct records. Thus a ubiquitous access to appropriate records is essential. Palm vein pattern recognition promises a secured patient record access. Likewise our paper reveals an efficient means to view, edit or transfer the DICOM images instantly which was a challenging task for medical practitioners in the

  12. Informal patient payments in maternity hospitals in Kiev, Ukraine. (United States)

    Stepurko, Tetiana; Pavlova, Milena; Levenets, Olena; Gryga, Irena; Groot, Wim


    Maternity care in Ukraine is a government priority. However, it has not undergone substantial changes since the collapse of the Soviet Union. Similar to the entire health care sector in Ukraine, maternity care suffers from inefficient funding, which results in low quality and poor access to services. The objective of this paper is to explore the practice of informal payments for maternity care in Ukraine, specifically in cases of childbirth in Kiev maternity hospitals. The paper provides an ethnographic study on the consumers' and providers' experiences with informal payments. The results suggest that informal payments for childbirth are an established practice in Kiev maternity hospitals. The bargaining process between the pregnant woman (incl. her partner) and the obstetrician is an important part of the predelivery arrangement, including the informal payment. To deal with informal payments in Kiev maternity hospitals, there is a need for the following: (i) regulation of the "quasi-official" patient payments at the health care facility level; and (ii) improvement of professional ethics through staff training. These strategies should be coupled with improved governance of the health care sector in general, and maternity care in particular in order to attain international quality standards and adequate access to facilities.

Methods: The Co-Dependence in Alzheimer's Disease study is an 18 multicenter, cross-sectional, observational study among patients with AD according to the clinical dementia rating score and their caregivers in Spain. This study also gathered data on resource utilization for medical care, social care, caregiver productivity losses, and informal caregiver time reported in the Resource Utilization in Dementia Lite instrument and a complementary questionnaire. The data of 343 patients and their caregivers were collected through the completion of a clinical report form during one visit/assessment at an outpatient center or hospital, where all instruments were administered. The data collected (in addition to clinical measures also included sociodemographic data concerning the patients and their caregivers. Cost analysis was based on resource use for medical care, social care, caregiver productivity losses, and informal caregiver time reported in the Resource Utilization in Dementia Lite instrument and a complementary questionnaire. Resource unit costs were applied to value direct medical-, social-, and indirect-care costs. A replacement cost method was used to value informal care. Patient dependence on others was measured using the Dependence Scale, and the Cumulative Index Rating Scale was administered to the patient to assess multi-morbidity. Multivariate regression analysis was used to model the effects of dependence and other sociodemographic and clinical variables on cost of care. Results: The mean (standard deviation costs per patient

  14. Clinical documentation as a source of information for patients - possibilities and limitations. (United States)

    Wibe, Torunn; Ekstedt, Mirjam; Hellesø, Ragnhild; Øyri, Karl; Slaughter, Laura


    Recent legislation in many countries has given patients the right to access their own patient records. Making health-care professionals' assessments and decisions more transparent by giving patients access to their records is expected to provide patients with useful health information and reduce the power imbalance between patient and provider. We conducted both a mail survey and a face-to-face interview study, including patients who had requested a paper copy of their patient records (EPR), to explore their experiences. For many study participants, a view of their records filled in holes in the oral information they previously received. They had problems understanding parts of what they read, but rarely asked for help. Instead they searched for explanations on the Internet or attempted to understand based on the context. Patients are still afraid of seeming suspicious or displeased if they indicate that they would like to read their records. Health-care organizations should consider actively offering patients the chance to view their clinical documentation to a larger extent than what has been done so far.

    Kamal, Jyoti; Pasuparthi, Kabardhi; Rogers, Patrick; Buskirk, Jason; Mekhjian, Hagop


    Success of a clinical trial recruitment process for drug discovery and new treatments depends on screening and identifying eligible patients in a timely manner. This can be a complex and tedious process that in many instances requires a research nurse to manually track patients that may be eligible. At the Ohio State University Medical Center (OSUMC) we have developed a web-based functional prototype that uses the data stored in the Information Warehouse (IW) to screen patients that meet the eligibility criteria for clinical trials. Using this prototype, a researcher can apply a set of inclusion/exclusion criteria pertinent to a research protocol and instantly find patients that may qualify for the clinical trial without revealing their identity. A researcher has access to all detailed historical clinical information such as lab results, diagnosis codes, pathology reports and clinical notes.

    Jian-Ming Liu; Ru-Xiang Xu; Yong-Sheng Hu; Lian-Kun Ren; Hui Qiao; Hu Ding; Zhi-Liang Liu


    Background: Most patients with epilepsy want to learn as much as possible about the disease, and many have turned to the internet for information.Patients are likely to use information obtained from the internet to control their epilepsy, but little is known about the accuracy of this information.In this survey, we have assessed the feasibility and usability ofinternet-based interventions for the treatment of epilepsy.Methods: Data were collected from an internet search.Different search terms were used to obtain general information on epilepsy together with information about medication, types of epilepsy, treatment, women's health, and other information.The accuracy of the information was evaluated by a group of experts.Results: A total of 1320 web pages were assessed.The majority were websites related to health.A large number (80.2%) of web pages contained content related to the search term.A significant number of web pages 450/1058 (42.5%) claimed to provide information from a credible source;however, only 206/1058 (19.5%) of the information was accurate and complete;326/1058 (30.8%) was accurate but incomplete;328/1058 (31.0%) was correct but nonstandard, and 198/1058 (18.8%) was inaccurate.The authenticity of the information was not significantly different between the two search engines (x2 =0.009, P =0.924).No significant difference was observed in the information obtained from a specialist or nonspecialist source (x2 =7.538, P =0.057).There was also no correlation between the quality of the information and the priority (x2 =6.880, P =0.076).Conclusions: Searching for information about epilepsy on the internet is convenient, but the information provided is not reliable.Too much information is inaccurate or for advertisement purposes, and it is difficult for patients to find the useful information.Turning to the internet for medical knowledge may be harmful.Physicians should be aware that their patients may search for information on the internet and

  17. Collection of Information Directly from Patients through an Adaptive Human-computer Interface (United States)

    Lobach, David F.; Arbanas, Jennifer M.; Mishra, Dharani D.; Wildemuth, Barbara; Campbell, Marci


    Clinical information collected directly from patients is critical to the practice of medicine. Past efforts to collect this information using computers have had limited utility because these efforts required users to be facile with the information collecting system. This poster describes the development and function of a computer system that uses technology to overcome the limitations of previous computer-based data collection tools by adapting the human-computer interface to fit the skills of the user. The system has been successfully used at two diverse clinical sites.

  18. Patient-Focused Benefit-Risk Analysis to Inform Regulatory Decisions: The European Union Perspective. (United States)

    Mühlbacher, Axel C; Juhnke, Christin; Beyer, Andrea R; Garner, Sarah

    Regulatory decisions are often based on multiple clinical end points, but the perspectives used to judge the relative importance of those end points are predominantly those of expert decision makers rather than of the patient. However, there is a growing awareness that active patient and public participation can improve decision making, increase acceptance of decisions, and improve adherence to treatments. The assessment of risk versus benefit requires not only information on clinical outcomes but also value judgments about which outcomes are important and whether the potential benefits outweigh the harms. There are a number of mechanisms for capturing the input of patients, and regulatory bodies within the European Union are participating in several initiatives. These can include patients directly participating in the regulatory decision-making process or using information derived from patients in empirical studies as part of the evidence considered. One promising method that is being explored is the elicitation of "patient preferences." Preferences, in this context, refer to the individual's evaluation of health outcomes and can be understood as statements regarding the relative desirability of a range of treatment options, treatment characteristics, and health states. Several methods for preference measurement have been proposed, and pilot studies have been undertaken to use patient preference information in regulatory decision making. This article describes how preferences are currently being considered in the benefit-risk assessment context, and shows how different methods of preference elicitation are used to support decision making within the European context.

    Full Text Available This study examined an instruction method for the improvement of information processing abilities in elementary school students. Current elementary students are required to develop information processing abilities to create new knowledge for this digital age. There is, however, a shortage of instruction strategies for these information processing abilities. This research proposes a method for teaching information processing abilities based on a problem-based learning model, and was tested with elementary students. The students developed an improved ability to create new knowledge and to present relationships with information through the process of problem solving. This study performed experimental research by comparing pre- and post-tests with twenty-three fifth grade elementary students over the course of eight months. This study produced a remarkable improvement in information selection, information reliability, information classification, information analysis, information comparison, and information internalization. This study presents an improved methodology for the teaching of information processing abilities.

  2. RFID based patient registration in mass casualty incidents

    Directory of Open Access Journals (Sweden)

    Nestler, Simon


    Full Text Available In MCIs (mass casualty incidents the EMC (emergency medical chief has to gain an overview on all patients at the scene. When using paper based patient tags the patient-related information remains at the patients themselves and the information relay is complex. We propose a mobile, RFID based solution, which makes the local patient-related information available to all relief workers at the scene. As a consequence all processes in an MCI are more transparent and the resulting medication and transport of the injured is more efficient. The introduction of RFID enhanced patient tags leads to various usability challenges which are discussed in this paper. Furthermore, three different implementations show, how these challenges can be solved in the future. These solutions have been evaluated in a disaster control exercise in order to get an impression of the practical suitability of the proposed solutions. The future introduction of RFID tags in rescue and emergency services can be based on this work.

  3. [The deaf patient--information for a barrier-free conversation with patients in dentistry]. (United States)

    Binggeli, Tatjana; Lussi, Adrian; Zimmerli, Brigitte


    There are about 650,000 people with hearing problems in Switzerland, 10,000 of whom use sign language. About 100,000 people are hard of hearing. Deaf patients require special treatment in the dental office as they have specific communication needs. This community, like many other minority groups, has a sign language and a culture of its own. To prevent misunderstandings it is therefore very important to provide solutions for an enhanced communication. However, guidelines for the communication with deaf dental patients are still missing. Successful communication between deaf patients and dentist is essential for effective care. This paper is concerned with providing background information and introducing recommendations for unrestricted dentist-patient communication. The aim of this article is to improve dentists' knowledge of the appropriate communication with this patient group.

  4. Information Expensiveness Perceived by Vietnamese Patients with Respect to Healthcare Provider’s Choice (United States)

    Quan-Hoang, Vuong


    Background: Patients have to acquire information to support their decision on choosing a suitable healthcare provider. But in developing countries like Vietnam, accessibility issues remain an obstacle, thus adversely affect both quality and costliness of healthcare information. Vietnamese use both sources from health professionals and friends/relatives, especially when quality of the Internet-based cheaper sources appear to be still questionable. The search of information from both professionals and friends/relatives incurs some cost, which can be viewed as low or high depending low or high accessibility to the sources. These views potentially affect their choices. Aim and Objectives: To investigate the effects that medical/health services information on perceived expensiveness of patients’ labor costs. Two related objectives are a) establishing empirical relations between accessibility to sources and expensiveness; and, b) probabilistic trends of probabilities for perceived expensiveness. Results: There is evidence for established relations among the variables “Convexp” and “Convrel” (all p’s < 0.01), indicating that both information sources (experts and friends/relatives) have influence on patients perception of information expensiveness. The use of experts source tends to increase the probability of perceived expensiveness. Conclusion: a) Probabilistic trends show Vietnamese patients have propensity to value healthcare information highly and do not see it as “expensive”; b) The majority of Vietnamese households still take non-professional advices at their own risks; c) There is more for the public healthcare information system to do to reduce costliness and risk of information. The Internet-based health service users communities cannot replace this system. PMID:28077894

  5. An information theory-based approach to modeling the information processing of NPP operators

    Energy Technology Data Exchange (ETDEWEB)

    Kim, Jong Hyun; Seong, Poong Hyun [Korea Advanced Institute, Taejon (Korea, Republic of)


    This paper proposes a quantitative approach to modeling the information processing of NPP operators. The aim of this work is to derive the amount of the information processed during a certain control task. The focus will be on i) developing a model for information processing of NPP operators and ii) quantifying the model. To resolve the problems of the previous approaches based on the information theory, i.e. the problems of single channel approaches, we primarily develop the information processing model having multiple stages, which contains information flows. Then the uncertainty of the information is quantified using the Conant's model, a kind of information theory.

  6. Developing a Web-Based Nursing Practice and Research Information Management System: A Pilot Study. (United States)

    Choi, Jeeyae; Lapp, Cathi; Hagle, Mary E


    Many hospital information systems have been developed and implemented to collect clinical data from the bedside and have used the information to improve patient care. Because of a growing awareness that the use of clinical information improves quality of care and patient outcomes, measuring tools (electronic and paper based) have been developed, but most of them require multiple steps of data collection and analysis. This necessitated the development of a Web-based Nursing Practice and Research Information Management System that processes clinical nursing data to measure nurses' delivery of care and its impact on patient outcomes and provides useful information to clinicians, administrators, researchers, and policy makers at the point of care. This pilot study developed a computer algorithm based on a falls prevention protocol and programmed the prototype Web-based Nursing Practice and Research Information Management System. It successfully measured performance of nursing care delivered and its impact on patient outcomes successfully using clinical nursing data from the study site. Although Nursing Practice and Research Information Management System was tested with small data sets, results of study revealed that it has the potential to measure nurses' delivery of care and its impact on patient outcomes, while pinpointing components of nursing process in need of improvement.

  7. Use of tablet personal computers for sensitive patient-reported information. (United States)

    Dupont, Alexandra; Wheeler, Jane; Herndon, James E; Coan, April; Zafar, S Yousuf; Hood, Linda; Patwardhan, Meenal; Shaw, Heather S; Lyerly, H Kim; Abernethy, Amy P


    Notebook-style computers (e/Tablets) are increasingly replacing paper methods for collecting patient-reported information. Discrepancies in data between these methods have been found in oncology for sexuality-related questions. A study was performed to formulate hypotheses regarding causes for discrepant responses and to analyze whether electronic data collection adds value over paper-based methods when collecting data on sensitive topics. A total of 56 breast cancer patients visiting Duke Breast Clinic (North Carolina) participated by responding to 12 subscales of 5 survey instruments in electronic (e/Tablet) format and to a paper version of 1 of these surveys, at each visit. Twenty-one participants (38%) provided dissimilar responses on paper and electronic surveys to one item of the Functional Assessment of Cancer Therapy-General (FACT-G) Social Well-Being scale that asked patients to rate their satisfaction with their current sex life. Among these 21 patients were 8 patients who answered the question in the electronic environment, and 13 patients who answered both paper and electronic versions but with different responses. Eleven patients (29%) did not respond to the item on either e/Tablet or paper; 45 patients (80%) answered it on e/Tablet; and 37 patients (66%) responded on the paper version. The e/Tablet electronic system may provide a "safer" environment than paper questionnaires for cancer patients to answer private or highly personal questions on sensitive topics such as sexuality.

    Full Text Available The world-wide-web offers a posse of textual information sources which are ready to be utilized for several applications. In fact, given the rapidly evolving nature of online data, there is a real risk of information overload unless we continue to develop and refine techniques to meaningfully segregate these information sources. Specifically, there is a dearth of content-oriented and intelligent techniques which can learn from past search experiences and also adapt to a user’s specific requirements during her current search. In this paper, we tackle the core issue of prioritizing textual information sources on the basis of the relevance of their content to the central theme that a user is currently exploring. We propose a new Source Prioritization Algorithm that adopts an iterative learning approach to assess the proclivity of given information sources towards a set of user-defined seed words in order to prioritise them. The final priorities obtained serve as initial priorities for the next search request. This serves a dual purpose. Firstly, the system learns incrementally from several users’ cumulative search experiences and re-adjusts the source priorities to reflect the acquired knowledge. Secondly, the refreshed source priorities are utilized to direct a user’s current search towards more relevant sources while adapting also to the new set of keywords acquired from that user. Experimental results show that the proposed algorithm progressively improves the system’s ability to discern between different sources, even in the presence of several random sources. Further, it is able to scale well to identify the augmented information source when a new enriched information source is generated by clubbing existing ones.

    Directory of Open Access Journals (Sweden)

    Ramazan Büyükkaya1


    Full Text Available Aim: It is observed that the patient compliance and technical quality is increased in sufficiently informed patients by the doctor at the examinations requested from the radiology clinics. We aimed to point to rate of the patients have been informed by the doctor about ultrasound and interventional radiological examinations requested from the clinical disciplines and accordingly encountered medical and ethic problems. Methods: Simple yes or no questions were asked to 1000 patients (550 male, mean age 44, 450 women, mean age 42 admitted to our clinic to assess their level of information about the investigation. Whether the patients were informed by the doctor, know why and what is the examination wanted and knowledge about the way of technique were asked to the patients simply and clearly. Results: 880 of 1000 (88% patients were not informed by the doctor about tests, 710 patients (71% had no information about the examination. Patients with information about research (290 patients classified according to source of the information; 120 patients were informed by the physician (41.4%, 90 patients (31% had examination before, 44 patients (15.2% received information from the relatives and other patients examined, while the remaining 36 patients (12.4% were found information from a variety of media organs and from the internet. Conclusion: As a result of our research it is concluded that information status of the patients about radiological examinations is insufficient and the patients are not informed adequately by clinicians. Patient non-compliance during the examination because of having no information or false information decreases the quality of the investigation and makes it difficult to reach the diagnosis.

  11. The effects of preparatory sensory information on ICU patients. (United States)

    Shi, Shu-Feng; Munjas, Barbara A; Wan, Thomas T H; Cowling, W Richard; Grap, Mary Jo; Wang, Bill B L


    Preparatory sensory information (PSI) has been found to have significant effects in reducing distress, tension, restlessness, negative moods, and anxiety, and also in reducing length of postoperative hospitalization during various threatening medical events, but no evidence has demonstrated the effect of PSI on a patient during ICU hospitalization. On the basis of Lazarus' theory, a structural equation model was developed to examine the role of the nursing intervention, PSI, as a significant factor influencing patients' processes of cognitive appraisals and coping, adaptational responses, and patient care outcomes during ICU hospitalization. The analytical model examined the net effect of PSI on outcomes, controlling for the effects of mastery, interpersonal trust, social support, socioeconomic status, severity of illness, age, and gender. A quasi-experiment was executed in four large acute care hospitals. Data were collected from 41 subjects in the control group and from 42 in the treatment group receiving PSI before ICU admission. Structural equation modeling was employed to test the proposed analytic model. The initial tests of model fit indicate that the original model did not fit the data well with GFI = 0.85, AGFI = 0.76, RMSEA = 0.059, p_close = 0.28, and critical N = 78. A revised model was developed, and the fit indices suggested an adequate fit with GFI = 0.90, AGFI = 0.84, RMSEA = 0.00, p_close = 0.89, and critical N = 109. These findings provide empirical support for Lazarus' theory on stress, appraisal, and coping. The findings also verify the beneficial effects of the nursing intervention of PSI on ICU patients.

  13. The digital divide in Internet-based patient education materials. (United States)

    Sun, Gordon H


    The ubiquity of the Internet has led to the widespread availability of health-related information to the public, and the subsequent empowerment of patients has fundamentally altered the patient-physician relationship. Among several concerns of physicians is the possibility that patients may be misinformed by information obtained from the Internet. One opportunity for health care providers to address this problem exists within Internet-based patient education materials (IPEMs). According to recent research in Otolaryngology-Head and Neck Surgery, IPEMs found within professional otolaryngology websites are written at the 8th- to 18th-grade reading comprehension level, essentially unchanged over the past 3 years. This greatly exceeds the fourth- to sixth-grade reading level recommended by the National Institutes of Health. Benefits, strategies, and challenges to improving the readability of IPEMs are discussed.

  14. Fragile Watermarking Based on Robust Hidden Information

    Institute of Scientific and Technical Information of China (English)

    张新鹏; 王朔中


    Block-wise fragile watermarks can be used to reveal maliciously tampered areas in multimedia products. However a forged content containing a cloned fragile watermark can be constructed by using a series of watermarked data. To defeat this type of counter-feit attack, a novel fragile watermarking technique is proposed in which different pseudo-random data are selected for different host products, and the generated fragile watermark is dependent upon the selected information. While inserting the fragile watermark, the pseudo-random information is also robustly embedded into the host data. Because of the difference between the selected information,different watermarked data cannot be used to forge illegal contents containing a valid fragile watermark.

The burden of obsessive compulsive disorder (OCD may lead persons with diagnosed or undiagnosed OCD, and their relatives, to search for good quality information on the Web. This study aimed to evaluate the quality of Web-based information on English-language sites dealing with OCD and to compare the quality of websites found through a general and a medically specialized search engine. Methods: Keywords related to OCD were entered into Google and OmniMedicalSearch. Websites were assessed on the basis of accountability, interactivity, readability, and content quality. The "Health on the Net" (HON quality label and the Brief DISCERN scale score were used as possible content quality indicators. Of the 235 links identified, 53 websites were analyzed. Results: The content quality of the OCD websites examined was relatively good. The use of a specialized search engine did not offer an advantage in finding websites with better content quality. A score ≥16 on the Brief DISCERN scale is associated with better content quality. Conclusion: This study shows the acceptability of the content quality of OCD websites. There is no advantage in searching for information with a specialized search engine rather than a general one. Practical implications: The Internet offers a number of high quality OCD websites. It remains critical, however, to have a provider–patient talk about the information found on the Web. Keywords: Internet, quality indicators, anxiety disorders, OCD, search engine

    Khazaal, Yasser; Chatton, Anne; Cochand, Sophie; Jermann, Françoise; Osiek, Christian; Bondolfi, Guido; Zullino, Daniele


    The present study aims to evaluate the quality of web-based information on gambling and to investigate potential content quality indicators. The following key words: gambling, pathological gambling, excessive gambling, gambling problem and gambling addiction were entered into two popular search engines: Google and Yahoo. Websites were assessed with a standardized proforma designed to rate sites on the basis of "accountability", "presentation", "interactivity", "readability" and "content quality". "Health on the Net" (HON) quality label, and DISCERN scale scores aiding people without content expertise to assess quality of written health publication were used to verify their efficiency as quality indicators. Of the 200 links identified, 75 websites were included. The results of the study indicate low scores on each of the measures. A composite global score appeared as a good content quality indicator. While gambling-related education websites for patients are common, their global quality is poor. There is a need for useful evidence-based information about gambling on the web. As the phenomenon has greatly increased, it could be relevant for Internet sites to improve their content by using global score as a quality indicator.

    Purpose Despite the Institute of Medicine’s (IOM) 2005 recommendation, few care organizations have instituted standard survivorship care plans (SCPs). Low health literacy and low English proficiency are important factors to consider in SCP development. Our study aimed to identify information needs and survivorship care plan preferences of low literacy, multi-lingual patients to support the transition from oncology to primary care and ongoing learning in survivorship. Methods We conducted focus groups in five languages with African American, Latina, Russian, Filipina, White, and Chinese medically underserved breast cancer patients. Topics explored included the transition to primary care, access to information, knowledge of treatment history, and perspectives on SCPs. Results Analysis of focus group data identified three themes: 1) the need for information and education on the transition between “active treatment” and “survivorship”; 2) information needed (and often not obtained) from providers; and 3) perspectives on SCP content and delivery. Conclusions Our data point to the need to develop a process as well as written information for medically underserved breast cancer patients. An SCP document will not replace direct communication with providers about treatment, symptom management and transition, a communication that is missing in participating safety-net patients’ experiences of cancer care. Women turned to peer support and community-based organizations in the absence of information from providers. Implications for Cancer Survivors “Clear and effective” communication of survivorship care for safety-net patients requires dedicated staff trained to address wide-ranging information needs and uncertainties.

    To synthesize findings from previous studies assessing information needs of primary care patients on the Internet and other information sources in a primary care setting. A systematic review of studies was conducted with a comprehensive search in multiple databases including OVID MEDLINE, CINAHL, and Scopus. The most common information needs among patients were information about an illness or medical condition and treatment methods, while the most common information sources were the Internet and patients' physicians. Overall, patients tend to prefer the Internet for the ease of access to information, while they trust their physicians more for their clinical expertise and experience. Barriers to information access via the Internet include the following: socio-demographic variables such as age, ethnicity, income, education, and occupation; information search skills; and reliability of health information.

    Dong Daoyi; Chen Zonghai; Jiang Shengxiang


    Looking upon every encoding state of quantum information systems as a quantum information pattern, A kind of pattern-distance between different patterns as a measurement of comparability of quantum information patterns is defined, and two kinds of recognition algorithms based on pattern-distance for quantum information are proposed. They can respectively recognize quantum information with known objective pattern and unknown objective pattern. In the two algorithms, the phases and occurrence probabilities of different eigenpatterns of quantum information are sufficiently considered. Two examples demonstrate the feasibility and effectiveness of the two recognition methods. These algorithms point out a new and important path for applications of quantum information and pattern recognition.

    The novel information criterion (NIC) algorithm can find the principal subspace quickly, but it is not an actual principal component analysis (PCA) algorithm and hence it cannot find the orthonormal eigen-space which corresponds to the principal component of input vector.This defect limits its application in practice.By weighting the neural network's output of NIC, a modified novel information criterion (MNIC) algorithm is presented.MNIC extractes the principal components and corresponding eigenvectors in a parallel online learning program, and overcomes the NIC's defect.It is proved to have a single global optimum and nonquadratic convergence rate, which is superior to the conventional PCA online algorithms such as Oja and LMSER.The relationship among Oja, LMSER and MNIC is exhibited.Simulations show that MNIC could converge to the optimum fast.The validity of MNIC is proved.

    Researchers and practitioners show increasing sinterest in utilizing patient-generated information on the Web. Although the HCI and CSCW communities have provided many exciting opportunities for exploring new ideas and building broad agenda in health, few venues offer a platform for interdisciplinary and collaborative brainstorming about design challenges and opportunities in this space. The goal of this workshop is to provide participants with opportunities to interact with stakeholders from diverse backgrounds and practices-researchers, practitioners, designers, programmers, and ethnographers-and together generate tangible design outcomes that utilize patient-generated information on the Web. Through small multidisciplinary group work, we will provide participants with new collaboration opportunities, understanding of the state of the art, inspiration for future work, and ideally avenues for continuing to develop research and design ideas generated at the workshop.

The main challenges for developing and implementing a fully functional process support system concern both technical and organizational/management aspects.

  14. Evaluation of the Quality of Online Information for Patients with Rare Cancers: Thyroid Cancer. (United States)

    Kuenzel, Ulrike; Monga Sindeu, Tabea; Schroth, Sarah; Huebner, Jutta; Herth, Natalie


    The Internet offers an easy and quick access to a vast amount of patient information. However, several studies point to the poor quality of many websites and the resulting hazards of false information. The aim of this study was to assess quality of information on thyroid cancer. A patients' search for information about thyroid cancer on German websites was simulated using the search engine Google and the patient portal "". The websites were assessed using a standardized instrument with formal and content aspects from the German Cancer Society. Supporting the results of prior studies that analysed patient information on the Internet, the data showed that the quality of patient information on thyroid cancer is highly heterogeneous depending on the website providers. The majority of website providers are represented by media and health providers other than health insurances, practices and professionals offering patient information of relatively poor quality. Moreover, most websites offer patient information of low-quality content. Only a few trustworthy, high-quality websites exist. Especially Google, a common search engine, focuses more on the dissemination of information than on quality aspects. In order to improve the patient information from the Internet, the visibility of high-quality websites must be improved. For that, education programs to improve patients' eHealth literacy are needed. A quick and easy evaluation tool for online information suited for patients should be implemented, and patients should be taught to integrate such a tool into their research process.

  15. Developing and testing a patient information booklet for thrombolysis used in acute stroke. (United States)

    Knapp, Peter; Wanklyn, Peter; Raynor, D K; Waxman, Robin


    Objective  Thrombolysis decreases the chance of post-stroke dependence, although its use carries significant risk, notably of intra-cerebral haemorrhage. Patients (and families) face an important risk/benefit decision before consenting. We drafted a patient information booklet for this purpose, and applied performance-based readability testing with the aim that the most important information in the booklet could be found and understood. Methods  The booklet was developed with reference to best practice in information writing and design. We User-Tested its performance on 56 people without prior experience of stroke. After reading the booklet they were asked to find and explain 15 pieces of information. The booklet was revised according to its performance and re-tested, until each item was found and understood by at least 80% of participants. Key findings  The four-page information booklet contained approximately 900 words, organised into six sections. A risk-palette graphic showed the chance of positive and negative outcomes. The booklet was tested on four participant cohorts and revised, including more bold text, re-wording, changing the title and changing the graphic to a coloured bar chart. Testing the final version on the fourth cohort of 20 people showed that each of the 15 tested items of information met the target of at least 80% participants being able to find and understand it. Conclusions  The use of information design and User Testing produced a booklet that is understandable by people with no prior experience of stroke. User Testing is an inexpensive and quick method to ensure that information intended for patients is usable.

  16. Information Needs of Cancer Patients and Perception of Impact of the Disease, of Self-Efficacy, and Locus of Control. (United States)

    Keinki, C; Seilacher, E; Ebel, M; Ruetters, D; Kessler, I; Stellamanns, J; Rudolph, I; Huebner, J


    The aim of our study was to investigate the relationship between information needs and cancer patients' perceptions of the impact of the disease, self-efficacy, and locus of control. Using a standardized questionnaire, we obtained data from patients who attended a series of lectures. The questionnaire included questions on their information needs, sources of information, satisfaction with information, and short questionnaires on self-efficacy, perception of the disease, and locus of control of reinforcement. Data was obtained from 185 patients. Our results showed that the sources of information that were most often used were physicians (84 %), print media (68 %), and the Internet (59 %); online fora (7.5 %), non-medical practitioners (9.7 %), and telephone-based counseling (8.6 %) were only used by a minority. Patients with a high perception of their own control over the disease more often used any source of information available to them and were more often interested in acquiring additional information. Higher self-efficacy was significantly associated with the need for information on all topics. Patients with a higher external locus of control significantly more often used sources of information and had significantly more need for additional information. By contrast, there were no associations with an internal locus of control. Neither external nor internal locus of control showed any associations with satisfaction with information. Information needs seem to be higher in patients with a high external locus of control and low self-efficacy. Physicians, other professionals, and institutions that provide information may take these relationships into consideration for tailoring their services to patients.

    LI Ren-pu; HUANG Dao; GAO Mao-ting


    It is helpful for people to understand the essence of rough set theory to study the concepts and operations of rough set theory from its information view. In this paper we address knowledge expression and knowledge reduction in incomplete information systems from the information view of rough set theory. First, by extending information entropy-based measures in complete information systems, two new measures of incomplete entropy and incomplete conditional entropy are presented for incomplete information systems. And then, based on these measures the problem of knowledge reduction in incomplete information systems is analyzed and the reduct definitions in incomplete information system and incomplete decision table are proposed respectively. Finally,the reduct definitions based on incomplete entropy and the reduct definitions based on similarity relation are compared. Two equivalent relationships between them are proved by theorems and an in equivalent relationship between them is illustrated by an example. The work of this paper extends the research of rough set theory from information view to incomplete information systems and establishes the theoretical basis for seeking efficient algorithm of knowledge acquisition in incomplete information systems.

    CERN Multimedia


    RD38 : Modern High Energy Physics experiments and accelerators require sophisticated control systems to ensure their safe operation and to optimise their performance. Due to their complexity and to the large number of sensors needed for these purposes, they turn out to be difficult and costly to maintain with the present technology. The situation will seriously worsen with the LHC era. Various R\\&D departments of industrial companies are directly concerned with similar difficulties in power plants and complex automated systems. We propose to combine our efforts to study the various aspects of this problem. We intend to outline the main building blocks of generic control information system. As a result of this study we aim to provide technical solutions which could later be the major components of a basic turnkey system for medium to large scale HEP experiments and accelerators.

  4. Quality assessment of patient leaflets on misoprostol-induced labour: does written information adhere to international standards for patient involvement and informed consent? (United States)

    Clausen, Jette Aaroe; Rydahl, Eva


    Objectives The need for thorough patient information is increasing as maternity care becomes more medicalised. The aim was to assess the quality of written patient information on labour induction. In most Danish hospitals, misoprostol is the first-choice drug for induction in low-risk pregnancies. Misoprostol has been associated with adverse side effects and severe outcomes for mother and child and is not registered for obstetric use in Denmark. Setting Secondary care hospitals in Denmark. Data Patient information leaflets from all hospitals that used misoprostol as an induction agent by June 2015 (N=13). Design Patient leaflets were evaluated according to a validated scoring tool (International Patient Decision Aid Standards instrument, IPDAS), core elements in the Danish Health Act, and items regarding off-label use and non-registered medication. Two of the authors scored all leaflets independently. Outcome measures Women's involvement in decision-making, information on benefits and harms associated with the treatment, other justifiable treatment options, and non-registered treatment. Results Generally, the hospitals scored low on the IPDAS checklist. No hospitals encouraged women to consider their preferences. Information on side effects and adverse outcomes was poorly covered and varied substantially between hospitals. Few hospitals informed about precautions regarding outpatient inductions, and none informed about the lack of evidence on the safety of this procedure. None informed that misoprostol is not registered for induction or explained the meaning of off-label use or use of non-registered medication. Elements such as interprofessional consensus, long-term experience, and health authorities' approval were used to add credibility to the use of misoprostol. Conclusions Central criteria for patient involvement and informed consent were not met, and the patient leaflets did not inform according to current evidence on misoprostol-induced labour. Our findings

    Desplenter FA


    Full Text Available Background: Medicine information is an integral part of patient care and a patient right. In particular, patients with a mental health diagnosis have a need for information on medicines. Objective: This study aims to describe the current practice on information provision on antidepressants to inpatients in psychiatric hospitals.Methods: A qualitative study was conducted consisting of semi-structured interviews with health care professionals (n=46 and patients (n=17 in 11 Flemish psychiatric hospitals. Two topic guides were designed for conducting the interviews with these respective stakeholders. The issues addressed in the topic guides related to: organization of information provision in the hospital, information on demand of the patient, information provision by health care professionals, information for relatives, evaluation of provided information, interdisciplinary contacts on information provision and satisfaction on current practice of information provision. The interviews were analysed according to the five stages of the framework analysis.Results: Psychiatrists and nurses are the key players to provide information on antidepressants. Their approach depends on patient characteristics and mental state. Information is provided mainly orally. Health care professionals consider non-verbal cues of patients to verify if information has been understood. Health care professionals reported lack of time and lack of interdisciplinary contacts as negative aspects. Patients indicated that health care professionals take too little initiative to provide medicine information. Conclusions: Patients are informed about their antidepressants through various pathways. Although the awareness is present of the importance of the individual approach and efforts are done to tailor information to the individual patient, improvement is still possible. Tailoring communication; assessing patient needs and preferences; matching of health care professional style and

  13. Knowledge and Demand for Information about Islet Transplantation in Patients with Type 1 Diabetes

    Directory of Open Access Journals (Sweden)

    Yuko Yamamoto


    Full Text Available This cross-sectional study based on self-administrated questionnaire was conducted to investigate knowledge, related factors, and sources of information regarding islet transplantation in patients with type 1 diabetes in Japan. Among 137 patients who provided valid responses, 67 (48.9% knew about islet transplantation. Their main source of information was newspapers or magazines (56.7% and television or radio (46.3%. However, 85.8% of patients preferred the attending physician as their source of information. Although more than half of the patients were correctly aware of issues related to islet transplantation, the following specific issues for islet transplantation were not understood or considered, and there was little knowledge of them: need for immunosuppressants, lifestyle and dietary adaptations, fewer bodily burdens, and complications. The experience of hypoglycaemia, a high level of academic background, frequent self-monitoring of blood glucose, and the use of continuous subcutaneous insulin infusion were related to higher knowledge about islet transplantation.

  14. Physicians' communicative strategies in interacting with Internet-informed patients: results from a qualitative study. (United States)

    Caiata-Zufferey, Maria; Schulz, Peter J


    This article describes the strategies used by physicians to interact with Internet-informed patients, alongside illustrating the motives underlying such strategies. Semistructured interviews were conducted with a sample of 17 physicians from primary care and medical specialist practices in the Italian part of Switzerland. The sample was diversified in terms of specialty, age, and gender. Data collection and analysis were driven by grounded theory and supported by a computer-assisted qualitative analysis program. A typology of four communicative strategies has been outlined. The adoption of these strategies is shaped by physicians' general attitude toward Internet-informed patients, based on their conception of medical information for lay people through the Internet. However, this general attitude is mediated by doctors' interpretation of the specific communicative context, that is, their appraisal of three aspects: the patient's health literacy, the relevance of the online information to be discussed, and their own communicative efficacy. At the end, the process of interpretation underlying the strategies is discussed to expand on it and to identify implications for practice and research.

    Directory of Open Access Journals (Sweden)



    Full Text Available Introduction: Medical student should be trained in medical ethics and one of the most essential issues in this field is taking informed consents. In this research, we compared the effect of effectiveness of teaching methods on students’ ability in taking informed consent from patients. Methods: This semi-experimental study was carried out on fifty eight subjects from the 4th-year students of Shiraz University of Medical Sciences who attended in medical ethics course before their ‘clinical clerkship’training.Method of sampling was census and students were randomly allocated into two groups of control group (n=28 was trained in traditional lecture-based class and the case groupnamed as A1 (n=22 were taught by video-taped examples of standardized patient.Then A1 group attended in traditional lecture-based classes named as A2. The groups were evaluated in terms the ability of recognition of ethical issues through the scenario based ethical examination before and after each training. Scenarios were related to the topics of informed consent. Data were analyzed by SPSS 14 software using descriptive statistics and anova test. P-value less than 0.05 was considered as significant. Results: The mean scores results of A2, A1 and B group were found to be 7.21, 5.91 and 5.73 out of 8, respectively. Comparison between the groups demonstrated that the ability of taking informed consent was significantly higher in A2 group (p<0.001, followed by A1 group (p<0.05, while was the least in the B group (p=0.875. Conclusion: According to this research, lecture-based teaching is still of great value in teaching medical ethics, but when combined with standardized patient, the outcome will be much better. It should be considered that mixed methods of teaching should be used together for better result.

  18. Cultural competency, autonomy, and spiritual conflicts related to Reiki/CAM therapies: Should patients be informed? (United States)

    Arvonio, Maria Marra


    The use of complementary and alternative medicines (CAM) such as Reiki is on the rise in healthcare centers. Reiki is associated with a spirituality that conflicts with some belief systems. Catholic healthcare facilities are restricted from offering this therapy because it conflicts with the teachings of the Catholic Church. However, hospitals are offering it without disclosing the spiritual aspects of it to patients. This article will address the ethical concerns and possible legal implications associated with the present process of offering Reiki. It will address these concerns based on the Joint Commission's Standard of Cultural Competency and the ethical principles of autonomy and informed consent. A proposal will also be introduced identifying specific information which Reiki/CAM practitioners should offer to their patients out of respect of their autonomy as well as their cultural, spiritual, and religious beliefs.

  19. Sample-Based Vegetation Distribution Information Synthesis.

    Directory of Open Access Journals (Sweden)

    Chanchan Xu

    Full Text Available In constructing and visualizing a virtual three-dimensional forest scene, we must first obtain the vegetation distribution, namely, the location of each plant in the forest. Because the forest contains a large number of plants, the distribution of each plant is difficult to obtain from actual measurement methods. Random approaches are used as common solutions to simulate a forest distribution but fail to reflect the specific biological arrangements among types of plants. Observations show that plants in the forest tend to generate particular distribution patterns due to growth competition and specific habitats. This pattern, which represents a local feature in the distribution and occurs repeatedly in the forest, is in line with the "locality" and "static" characteristics in the "texture data", making it possible to use a sample-based texture synthesis strategy to build the distribution. We propose a vegetation distribution data generation method that uses sample-based vector pattern synthesis. A sample forest stand is obtained first and recorded as a two-dimensional vector-element distribution pattern. Next, the large-scale vegetation distribution pattern is synthesized automatically using the proposed vector pattern synthesis algorithm. The synthesized distribution pattern resembles the sample pattern in the distribution features. The vector pattern synthesis algorithm proposed in this paper adopts a neighborhood comparison technique based on histogram matching, which makes it efficient and easy to implement. Experiments show that the distribution pattern synthesized with this method can sufficiently preserve the features of the sample distribution pattern, making our method meaningful for constructing realistic forest scenes.

  1. A Location-Based Business Information Recommendation Algorithm

    Directory of Open Access Journals (Sweden)

    Shudong Liu


    Full Text Available Recently, many researches on information (e.g., POI, ADs recommendation based on location have been done in both research and industry. In this paper, we firstly construct a region-based location graph (RLG, in which region node respectively connects with user node and business information node, and then we propose a location-based recommendation algorithm based on RLG, which can combine with user short-ranged mobility formed by daily activity and long-distance mobility formed by social network ties and sequentially can recommend local business information and long-distance business information to users. Moreover, it can combine user-based collaborative filtering with item-based collaborative filtering, and it can alleviate cold start problem which traditional recommender systems often suffer from. Empirical studies from large-scale real-world data from Yelp demonstrate that our method outperforms other methods on the aspect of recommendation accuracy.

    Full Text Available Objectives. Existing findings on cancer patients' use of information sources were synthesized to 1 rank the most and least used information sources and the most helpful information sources and to 2 find the impact of patient demographics and situations on use of information sources. Method. . To synthesize results found across studies, a systematic review was conducted. Medline and CINAHL were searched to retrieve literature on cancer patients' information source use. The retrieved articles were carefully selected according to predetermined criteria, and several articles were eliminated in a systematic approach. Analysis. The twelve articles that met the criteria were systematically analysed by extracting data from articles and summarizing data for the purpose of synthesis to determine the meaning of findings on most used information sources, least used information sources, most helpful information sources, effect of patient characteristics on preference for an information source, and effect of patient situations on preference for an information source. Results. In descending order of use, health care professionals, medical pamphlets, and family and friends were most used information sources. Internet and support groups were least used. In descending order of helpfulness, books, health care professionals and medical pamphlets were found to be most helpful information sources. Younger patients used health care professionals and certain forms of written information sources more than older patients. Conclusion. . The systematic review shows that many areas of cancer patients' information source use have been either neglected or barely analysed. An in-depth understanding of cancer patients' use of information sources and the characteristics in information sources they consider to be helpful is important for developing successful interventions to better inform patients.

  3. A secure biometrics-based authentication scheme for telecare medicine information systems. (United States)

    Yan, Xiaopeng; Li, Weiheng; Li, Ping; Wang, Jiantao; Hao, Xinhong; Gong, Peng


    The telecare medicine information system (TMIS) allows patients and doctors to access medical services or medical information at remote sites. Therefore, it could bring us very big convenient. To safeguard patients' privacy, authentication schemes for the TMIS attracted wide attention. Recently, Tan proposed an efficient biometrics-based authentication scheme for the TMIS and claimed their scheme could withstand various attacks. However, in this paper, we point out that Tan's scheme is vulnerable to the Denial-of-Service attack. To enhance security, we also propose an improved scheme based on Tan's work. Security and performance analysis shows our scheme not only could overcome weakness in Tan's scheme but also has better performance.

This middleware-based system unifies and encodes the data from all sorts of detectors, and integrates the multi-mode transmission, data preprocessing, and data fusion. Compared with the traditional traffic information collection system, the proposed system overcomes the data loss, data noise, and especially the data multiple source, decreases the data redundancy, and ensures the data accuracy with better security and expandability

  8. What information should patients be given before radiotherapy?;Quelle information pour les patients avant une radiotherapie?

    Energy Technology Data Exchange (ETDEWEB)

    Bergerot, Ph. [Ligue Nationale Contre le Cancer (LNCC), Collectif Inter Associatif sur la Sante - CISS, 75 - Paris (France)


    Following a number of accidents at radiotherapy units, at Epinal and Toulouse hospitals in particular, and the problems encountered in the summer 2008, mainly caused by a shortage of radiation physicians and probably due to legislation that bears little relation to reality, a national radiotherapy monitoring committee was set up on 15 December 2008 in the presence of Roselyne Bachelot-Narquin, France's Minister for Health and Sport. A first progress report was submitted to the Minister in May 2009. Twelve members sit on this national monitoring committee, including a CISS representative and a person that has received radiotherapy treatment. This demonstrates the seriousness and the commitment required of users on this issue. Radiotherapy, one of the main treatments for cancer, is a loco-regional treatment that uses radiation capable of destroying cancer cells. It can be used on its own, or before, during or after another treatment method (surgery or a medical treatment such as chemotherapy, for example). The decision to treat a patient by means of radiotherapy is based on the opinions of health care professionals discussed at a multidisciplinary team meeting, the minutes of which are sent to the various doctors involved. The radiotherapy treatment prescribed (the technique, total radiation dose, length of the treatment, number of sessions, etc.) is adapted to the individual situation of each patient. It is designed to be as effective as possible in light of the tumour pathology, while protecting neighbouring organs as far as is possible. (author)

  13. Location-based health information services: a new paradigm in personalised information delivery

    Directory of Open Access Journals (Sweden)

    Boulos Maged


    Full Text Available Abstract Brute health information delivery to various devices can be easily achieved these days, making health information instantly available whenever it is needed and nearly anywhere. However, brute health information delivery risks overloading users with unnecessary information that does not answer their actual needs, and might even act as noise, masking any other useful and relevant information delivered with it. Users' profiles and needs are definitely affected by where they are, and this should be taken into consideration when personalising and delivering information to users in different locations. The main goal of location-based health information services is to allow better presentation of the distribution of health and healthcare needs and Internet resources answering them across a geographical area, with the aim to provide users with better support for informed decision-making. Personalised information delivery requires the acquisition of high quality metadata about not only information resources, but also information service users, their geographical location and their devices. Throughout this review, experience from a related online health information service, HealthCyberMap, is referred to as a model that can be easily adapted to other similar services. HealthCyberMap is a Web-based directory service of medical/health Internet resources exploring new means to organise and present these resources based on consumer and provider locations, as well as the geographical coverage or scope of indexed resources. The paper also provides a concise review of location-based services, technologies for detecting user location (including IP geolocation, and their potential applications in health and healthcare.

  14. Attribute reduction in interval-valued information systems based on information entropies

    Institute of Scientific and Technical Information of China (English)

    Jian-hua DAI; Hu HU; Guo-jie ZHENG; Qing-hua HU; Hui-feng HAN; Hong SHI


    Interval-valued data appear as a way to represent the uncertainty affecting the observed values. Dealing with interval-valued information systems is helpful to generalize the applications of rough set theory. Attribute reduction is a key issue in analysis of interval-valued data. Existing attribute reduction methods for single-valued data are unsuitable for interval-valued data. So far, there have been few studies on attribute reduction methods for interval-valued data. In this paper, we propose a framework for attribute reduction in interval-valued data from the viewpoint of information theory. Some information theory concepts, including entropy, conditional entropy, and joint entropy, are given in interval-valued information systems. Based on these concepts, we provide an information theory view for attribute reduction in interval-valued information systems. Consequently, attribute reduction algorithms are proposed. Experiments show that the proposed framework is effective for attribute reduction in interval-valued information systems.

  15. Ontological Model-Based Transparent Access To Information In A Medical Multi-Agent System

    Directory of Open Access Journals (Sweden)

    Felicia GÎZĂ-BELCIUG


    Full Text Available Getting the full electronic medical record of a patient is an important step in providing a quality medical service. But the degree of heterogeneity of data from health unit informational systems is very high, because each unit can have a different model for storing patients’ medical data. In order to achieve the interoperability and integration of data from various medical units that store partial patient medical information, this paper proposes a multi-agent systems and ontology based approach. Therefore, we present an ontological model for describing the particular structure of the data integration process. The system is to be used for centralizing the information from a patient’s partial medical records. The main advantage of the proposed model is the low ratio between the complexity of the model and the amount of information that can be retrieved in order to generate the complete medical history of a patient.

    Mullan J


    Full Text Available Objective: To explore healthcare professionals’ views about the benefits and challenges of using information technology (IT resources for educating patients about their warfarin therapy.Methods: A cross-sectional survey of both community and hospital-based healthcare professionals (e.g., doctors, pharmacists and nurses involved using a purpose-designed questionnaire. The questionnaires were distributed using a multi-modal approach to maximise response rates.Results: Of the total 300 questionnaires distributed, 109 completed surveys were received (43.3% response rate. Over half (53.2% of the healthcare participants were aged between 40-59 years, the majority (59.5% of whom were female. Fifty nine (54.1% participants reported having had no access to warfarin-specific IT-based patient education resources, and a further 19 (38.0% of the participants who had IT-access reported that they never used such resources. According to the healthcare participants, the main challenges associated with educating their patients about warfarin therapy included: patient-related factors, such as older age, language barriers, cognitive impairments and/or ethnic backgrounds or healthcare professional factors, such as time constraints. The healthcare professionals reported that there were several aspects about warfarin therapy which they found difficult to educate their patients about which is why they identified computers and interactive touch screen kiosks as preferred IT devices to deliver warfarin education resources in general practices, hospital-based clinics and community pharmacies. At the same time, the healthcare professionals also identified a number of facilitators (e.g., to reinforce warfarin education, to offer reliable and easily comprehensible information and barriers (e.g., time and costs of using IT resources, difficulty in operating the resources that could impact on the effective implementation of these devices in educating patients about their

  18. Balancing digital information-sharing and patient privacy when engaging families in the intensive care unit. (United States)

    Brown, Samuel M; Aboumatar, Hanan J; Francis, Leslie; Halamka, John; Rozenblum, Ronen; Rubin, Eileen; Sarnoff Lee, Barbara; Sugarman, Jeremy; Turner, Kathleen; Vorwaller, Micah; Frosch, Dominick L


    Patients in intensive care units (ICUs) may lack decisional capacity and may depend on proxy decision makers (PDMs) to make medical decisions on their behalf. High-quality information-sharing with PDMs, including through such means as health information technology, could improve communication and decision making and could potentially minimize the psychological consequences of an ICU stay for both patients and their family members. However, alongside these anticipated benefits of information-sharing are risks of unwanted disclosure of sensitive information. Approaches to identifying the optimal balance between access to digital health information to facilitate engagement and protecting patient privacy are urgently needed. We identified eight themes that should be considered in balancing health information access and patient privacy: 1) potential benefits to patients from PDM data access; 2) potential harms to patients from such access; 3) the moral status of families within the patient-clinician relationship; 4) the scope of relevant information provided to PDMs; 5) issues around defining PDMs' authority; 6) methods for eliciting and documenting patient preferences about their family's information access; 7) the relevance of methods for ascertaining the identity of PDMs; and 8) the obligations of hospitals to prevent privacy breaches by PDMs. We conclude that PDMs should typically have access to health information from the current episode of care when the patient is decisionally impaired, unless the patient has previously expressed a clear preference that PDMs not have such access.

  1. Constructing a knowledge-based database for dermatological integrative medical information. (United States)

    Shin, Jeeyoung; Jo, Yunju; Bae, Hyunsu; Hong, Moochang; Shin, Minkyu; Kim, Yangseok


    Recently, overuse of steroids and immunosuppressive drugs has produced incurable dermatological health problems. Traditional medical approaches have been studied for alternative solutions. However, accessing relevant information is difficult given the differences in information for western medicine (WM) and traditional medicine (TM). Therefore, an integrated medical information infrastructure must be utilized to bridge western and traditional treatments. In this study, WM and TM information was collected based on literature searches and information from internet databases on dermatological issues. Additionally, definitions for unified terminology and disease categorization based on individual cases were generated. Also a searchable database system was established that may be a possible model system for integrating both WM and TM medical information on dermatological conditions. Such a system will yield benefits for researchers and facilitate the best possible medical solutions for patients. The DIMI is freely available online.

  2. The neglected topic: presentation of cost information in patient decision AIDS. (United States)

    Blumenthal-Barby, J S; Robinson, Emily; Cantor, Scott B; Naik, Aanand D; Russell, Heidi Voelker; Volk, Robert J


    Costs are an important component of patients' decision making, but a comparatively underemphasized aspect of formal shared decision making. We hypothesized that decision aids also avoid discussion of costs, despite their being tools designed to facilitate shared decision making about patient-centered outcomes. We sought to define the frequency of cost-related information and identify the common modes of presenting cost and cost-related information in the 290 decision aids catalogued in the Ottawa Hospital Research Institute's Decision Aid Library Inventory (DALI) system. We found that 56% (n = 161) of the decision aids mentioned cost in some way, but only 13% (n = 37) gave a specific price or range of prices. We identified 9 different ways in which cost was mentioned. The most common approach was as a "pro" of one of the treatment options (e.g., "you avoid the cost of medication"). Of the 37 decision aids that gave specific prices or ranges of prices for treatment options, only 2 were about surgery decisions despite the fact that surgery decision aids were the most common. Our findings suggest that presentation of cost information in decision aids is highly variable. Evidence-based guidelines should be developed by the International Patient Decision Aid Standards (IPDAS) Collaboration.

    Wang, Wei Dong; Du, Xiang Gang; Xie, Cui Ming


    Take account of the characters of road geological hazard and its supervision, it is very important to develop the Road Landslides Information Management and Forecasting System based on Geographic Information System (GIS). The paper presents the system objective, function, component modules and key techniques in the procedure of system development. The system, based on the spatial information and attribute information of road geological hazard, was developed and applied in Guizhou, a province of China where there are numerous and typical landslides. The manager of communication, using the system, can visually inquire all road landslides information based on regional road network or on the monitoring network of individual landslide. Furthermore, the system, integrated with mathematical prediction models and the GIS's strongpoint on spatial analyzing, can assess and predict landslide developing procedure according to the field monitoring data. Thus, it can efficiently assists the road construction or management units in making decision to control the landslides and to reduce human vulnerability.

    We proposed a novel kinetic energy decomposition analysis based on information theory. Since the Hirshfeld partitioning for electron densities can be formulated in terms of Kullback-Leibler information deficiency in information theory, a similar partitioning for kinetic energy densities was newly proposed. The numerical assessments confirm that the current kinetic energy decomposition scheme provides reasonable chemical pictures for ionic and covalent molecules, and can also estimate atomic energies using a correction with viral ratios.

  6. [Review of drug information provided to patients from the viewpoint of hospital pharmacists]. (United States)

    Orii, Takao


    Risks for patients and consumers can be minimized depending on how they are provided appropriate drug information. Therefore, from the viewpoint of hospital pharmacists, I would like to report on how information should be provided in order to minimize patient risk. For example, there is an ongoing opinion that the provision of easy-to-understand drug information to patients and consumers "does not appear necessary". The reasons for this include the following: Because the level of understanding varies greatly among patients, it is difficult to define what "easy-to-understand" information entails; rather, it may cause misunderstanding. These problems occur repeatedly if they are resolved by individual institutions. Therefore, it is essential to standardize the drug information provided to patients, that is, to establish a system to transmit drug information to patients and consumers. Regardless of whether the development of a hospital information system is in progress or not, it can be said that the development of such information systems is gradually spreading outside of hospitals and the situation is changing. From the viewpoint of patients, medical services are not limited to those from hospitals. Patient-centered collaboration between hospitals/clinics and pharmacies (but not the collaboration between hospital pharmacists and community pharmacists (why not?)) can provide good medical services only if patient information is shared. It is essential to establish a system for providing a drug guide for patients, in order to have patients understand drug information. The preparation of Drug Information for Patients would provide health care specialists a communication tool that helps minimize patient risk.

  7. [Objective assessment of symptoms and informing patients of surgical risks]. (United States)

    de Tayrac, Renaud; Letouzey, Vincent; Marès, Pierre


    Genital prolapse is a functional pathology presenting with numerous urinary, genito-sexual, and anorectal symptoms. These symptoms are responsible for an alteration of the quality of life, sometimes associated to a real anxiety-depressive syndrome. Because of these complex intricacies, the management of these disorders became multidisciplinary. Tools to measure the impact of prolapse symptoms on the quality of life became a necessity. Such instruments should allow a correlation of the functional symptomatology at the anatomic stage, raise a surgical indication based on the functional disturbance and evaluate the effectiveness and tolerance of the various therapeutic procedures. Two validated self-questionnaires in French (short versions of the Pelvic Floor Distress Inventory [PFDI-20] and the Pelvic Floor Impact Questionnaire [PFIQ-7]) are presently available. Moreover, the physician has the legal obligation to provide detailed presurgical information on frequent and severe hazards, expected benefits, functional consequences, therapeutic alternatives and the consequences of nonintervention. Before surgery takes place, the surgical approach, the benefit of using synthetic prostheses, the possibility of uterine and/or ovarian conservation, and some risky conditions such as smoking, obesity and estrogen deficiency should be discussed.

  8. Informed Systems: Enabling Collaborative Evidence Based Organizational Learning

    Directory of Open Access Journals (Sweden)

    Mary M. Somerville


    Full Text Available Objective – In response to unrelenting disruptions in academic publishing and higher education ecosystems, the Informed Systems approach supports evidence based professional activities to make decisions and take actions. This conceptual paper presents two core models, Informed Systems Leadership Model and Collaborative Evidence-Based Information Process Model, whereby co-workers learn to make informed decisions by identifying the decisions to be made and the information required for those decisions. This is accomplished through collaborative design and iterative evaluation of workplace systems, relationships, and practices. Over time, increasingly effective and efficient structures and processes for using information to learn further organizational renewal and advance nimble responsiveness amidst dynamically changing circumstances. Methods – The integrated Informed Systems approach to fostering persistent workplace inquiry has its genesis in three theories that together activate and enable robust information usage and organizational learning. The information- and learning-intensive theories of Peter Checkland in England, which advance systems design, stimulate participants’ appreciation during the design process of the potential for using information to learn. Within a co-designed environment, intentional social practices continue workplace learning, described by Christine Bruce in Australia as informed learning enacted through information experiences. In addition, in Japan, Ikujiro Nonaka’s theories foster information exchange processes and knowledge creation activities within and across organizational units. In combination, these theories promote the kind of learning made possible through evolving and transferable capacity to use information to learn through design and usage of collaborative communication systems with associated professional practices. Informed Systems therein draws from three antecedent theories to create an original

    Directory of Open Access Journals (Sweden)

    Hasan Ashrafi-rizi


    Full Text Available The role of information is undeniable in promoting public health (1-3. “Access to health information for all” was the slogan of the World Health Organization in 2004 (4. The proving of this slogan requires access to health information by beneficiaries (health professionals and patients. Access to health information by specialists as partly been achieved, but access to health information for patients and their families is considered low (5-7, which could have adverse effects. Health professionals have quick and easy access to information through libraries and medical information centers, participation in seminars, exchange of scientific information with other professionals, as well as identifying ways to effectively access to health information, but patients and their families do not have access to such facilities and capabilities. Therefore, patients and their families are faced with a phenomenon known as “inequity in access to health information” and the continuation of the injustice leads to health information poverty. Thus, the main question now is what we should do? It seems that the government needs to develop a national policy in the field of health information and it is the most important step. In the next step, the government should expand the concept production via using potentials of different organizations like public media (TV and Radio, health ministry and press and increase the access of patients to health information in the easy language (level of health information between health professionals and patients is different.

  14. The Measuring Your Health study: Leveraging community-based cancer registry recruitment to establish a large, diverse cohort of cancer survivors for analyses of measurement equivalence and validity of the Patient Reported Outcomes Measurement Information System® (PROMIS® short form items

    Directory of Open Access Journals (Sweden)

    Roxanne E. Jensen


    Full Text Available The Measuring Your Health (MY-Health study was designed to fill evidence gaps by validating eight Patient Reported Outcomes Measurement Information System® (PROMIS® domains (Anxiety, Depression, Fatigue, Pain Interference, Physical Function, Sleep Disturbance, Applied Cognitive Function, and Ability to Participate in Social Roles and Activities across multiple race-ethnic and age groups in a diverse cohort of cancer patients. This paper provides detailed information on MY-Health study design, implementation, and participant cohort; it identifies key challenges and benefits of recruiting a diverse community-based cancer cohort. Between 2010 and 2012, we identified eligible patients for the MY-Health study in partnership with four Surveillance, Epidemiology, and End Results (SEER program cancer registries located in California, Louisiana, and New Jersey. The overall response rate for the MY-Health cohort (n = 5,506 was 34 %, with a median response time of 9.5 months after initial cancer diagnosis. The cohort represented meaningful diversity of age (22 % under 49 years of age and race/ethnicity (41 % non-Hispanic White across seven cancers. Challenges included lower response rates by race/ethnic minorities, young, and advanced-stage cancer patients, use of non-final registry information for eligibility identification, and lower use of translated surveys than expected. The MY-Health cohort represents one of the largest efforts to measure the full range of patient-reported symptoms experienced after initial cancer treatment. It provides sufficient diversity in terms of sociodemographics, symptoms, and function to provide a meaningful validation of eight PROMIS measures.

  15. GIS information organization based on the Semantic Geospatial Web (United States)

    Li, Shuxia; Su, Xuming; Li, Ke


    People typically use geographic names instead of coordinates to find geographic information on the web through a search engine. But the current keyword-based web search engines are poorly adapted to help people find information that relates to a particular geographic name, because they don't incorporate the geospatial semantic during the search process. The Semantic Web is a new semantic-based information-retrieval environment. We propose the information organization framework of the GIS semantic data according to the architecture of the Semantic Web, that is, the ontology, the metadata and the data source. Then we deal with the organization of the semantic data based on the three-layered framework respectively. As a focus, we present a novel method to disambiguate geographical name based on the ontology of the place.

    Pengyi Zhang


    Full Text Available This paper focuses on how to retrieve personalized multimedia information based on user interest which can be mined from user profile. After analyzing the related works, a general structure of the personalized multimedia information retrieval system is given, which combines online module and offline module. Firstly, we collect a large-sale of photos from multimedia information sharing websites. Then, we record the information of the users who upload the multimedia information. For a given user, we save his history data which could describe the multimedia data. Secondly, the relationship between contents of multimedia data and semantic information is analyzed and then the user interest model is constructed by a modified LDA model which can integrate all the influencing factors in the task of multimedia information retrieval. Thirdly, the query distributions of all the topics can be estimated by the proposed modified LDA model. Thirdly, based on the above offline computing process, the online personalized multimedia information ranking algorithm is given which utilize the user interest model and the query word. Fourthly, multimedia information retrieval results are obtained using the proposed personalized multimedia information ranking algorithm. Finally, performance evaluation is conducted by a series of experiments to test the performance of the proposed algorithm compared with other methods on different datasets.

  17. Patient information leaflets for medicines: using consumer testing to determine the most effective design. (United States)

    Dickinson, D; Raynor, D K; Duman, M


    Comprehensive medicine information leaflets for patients are now mandatory across the European Union. In 1997, the European Commission (EC) proposed a prescriptive 'model' for the leaflets and a method for consumer testing. This exploratory study compared consumers' ability to use a leaflet based on the EC model leaflet and an alternative leaflet based on best practice in information design (Mark II). The leaflets were tested in two matched groups of 20 consumers, who were required to find, and understand, 15 pieces of information in the leaflets. The target that each question should be answered correctly by 16 out of 20 consumers, was achieved for three of the 15 points in the EC leaflet, compared with eight in the Mark II leaflet. Open questioning confirmed the problems with the EC leaflet, including a failure to understand key concepts about medicine interactions and contraindications. This research demonstrates the benefits of consumer testing, ensuring that leaflets are patient-orientated. A rigid model leaflet would prevent these benefits from being utilised.

  18. Evaluating Written Patient Information for Eczema in German: Comparing the Reliability of Two Instruments, DISCERN and EQIP.

    Megan E McCool

    Full Text Available Patients actively seek information about how to cope with their health problems, but the quality of the information available varies. A number of instruments have been developed to assess the quality of patient information, primarily though in English. Little is known about the reliability of these instruments when applied to patient information in German. The objective of our study was to investigate and compare the reliability of two validated instruments, DISCERN and EQIP, in order to determine which of these instruments is better suited for a further study pertaining to the quality of information available to German patients with eczema. Two independent raters evaluated a random sample of 20 informational brochures in German. All the brochures addressed eczema as a disorder and/or therapy options and care. Intra-rater and inter-rater reliability were assessed by calculating intra-class correlation coefficients, agreement was tested with weighted kappas, and the correlation of the raters' scores for each instrument was measured with Pearson's correlation coefficient. DISCERN demonstrated substantial intra- and inter-rater reliability. It also showed slightly better agreement than EQIP. There was a strong correlation of the raters' scores for both instruments. The findings of this study support the reliability of both DISCERN and EQIP. However, based on the results of the inter-rater reliability, agreement and correlation analyses, we consider DISCERN to be the more precise tool for our project on patient information concerning the treatment and care of eczema.

  19. [Design and Implementation of a Mobile Operating Room Information Management System Based on Electronic Medical Record]. (United States)

    Liu, Baozhen; Liu, Zhiguo; Wang, Xianwen


    A mobile operating room information management system with electronic medical record (EMR) is designed to improve work efficiency and to enhance the patient information sharing. In the operating room, this system acquires the information from various medical devices through the Client/Server (C/S) pattern, and automatically generates XML-based EMR. Outside the operating room, this system provides information access service by using the Browser/Server (B/S) pattern. Software test shows that this system can correctly collect medical information from equipment and clearly display the real-time waveform. By achieving surgery records with higher quality and sharing the information among mobile medical units, this system can effectively reduce doctors' workload and promote the information construction of the field hospital.

  1. The daily life of patients with dementia: A comparative study between the information provided by the caregiver and direct patient assessment

    Directory of Open Access Journals (Sweden)

    Lucia Aparecida Bressan

    Full Text Available Abstract The functionality concept is very important, as the diagnosis of dementia presupposes the existence of functional impairment. Instruments assessing functional performance present some limitations. In most cases, the assessment is based on the caregiver's report. Some studies in international literature have evaluated this issue and concluded that a difference exists between the caregiver's report and direct patient assessment. American and European caregivers tend to underestimate the patient's functional limitations. However, this issue has hitherto not been investigated in our context. Objective: To compare the caregiver's information with direct assessment of the patient's performance based on the same functional assessment questionnaire. Methods: Seventy-two patients and caregivers were attended by the Occupational Therapy service of the Behavioral Neurology Outpatient Clinic between 1999 and 2001, 25 of whom fulfilled the inclusion criteria: having a confirmed diagnosis of dementia according to the DSM-IV; having attended three or more return appointments, and where the caregiver belonged to the patient's family nucleus. The remaining subjects were excluded because of non-adherence to treatment or refusal to participate in the study. The Functional Activities Questionnaire by Pfeffer et al., 1982 was applied to patients in a laboratory simulation, while another evaluator interviewed the respective caregivers. The data were analyzed based on the weighted Kappa coefficient, and Wilcoxon test. Results: There were significative differences between caregiver's answers and direct observation of the patient's performance. The information provided by the caregivers proved unreliable since caregivers underestimated the patient's functional capacity.

  2. Does Health Information in Mass Media Help or Hurt Patients? Investigation of Potential Negative Influence of Mass Media Health Information on Patients' Beliefs and Medication Regimen Adherence. (United States)

    Im, Heewon; Huh, Jisu


    As an important public health issue, patient medication non-adherence has drawn much attention, but research on the impact of mass media as an information source on patient medication adherence has been scant. Given that mass media often provide confusing and contradicting information regarding health/medical issues, this study examined the potential negative influence of exposure to health information in mass media on patients' beliefs about their illnesses and medications, and medication adherence, in comparison with the effects of exposure to another primary medication information source, physicians. Survey data obtained from patients on blood thinner regimens revealed that the frequency of exposure to health information in mass media was negatively related to accuracy of patients' beliefs about their medication benefits and patient medication adherence. On the other hand, frequency of visits with physicians was positively associated with patients' beliefs about their medication benefits but had no significant relation to medication regimen adherence. The implications of the study findings are discussed, and methodological limitations and suggestion for future research are presented.

  3. Information Filtering via Implicit Trust-based Network

    CERN Document Server

    Xuan, Zhao-Guo; Liu, Jian-Guo


    Based on the user-item bipartite network, collaborative filtering (CF) recommender systems predict users' interests according to their history collections, which is a promising way to solve the information exploration problem. However, CF algorithm encounters cold start and sparsity problems. The trust-based CF algorithm is implemented by collecting the users' trust statements, which is time-consuming and must use users' private friendship information. In this paper, we present a novel measurement to calculate users' implicit trust-based correlation by taking into account their average ratings, rating ranges, and the number of common rated items. By applying the similar idea to the items, a item-based CF algorithm is constructed. The simulation results on three benchmark data sets show that the performances of both user-based and item-based algorithms could be enhanced greatly. Finally, a hybrid algorithm is constructed by integrating the user-based and item-based algorithms, the simulation results indicate t...

    Clark Melissa A


    Full Text Available Abstract Background Two trials were conducted to compare emergency department patient comprehension of rapid HIV pre-test information using different methods to deliver this information. Methods Patients were enrolled for these two trials at a US emergency department between February 2005 and January 2006. In Trial One, patients were randomized to a no pre-test information or an in-person discussion arm. In Trial Two, a separate group of patients were randomized to an in-person discussion arm or a Tablet PC-based video arm. The video, "Do you know about rapid HIV testing?", and the in-person discussion contained identical Centers for Disease Control and Prevention-suggested pre-test information components as well as information on rapid HIV testing with OraQuick®. Participants were compared by information arm on their comprehension of the pre-test information by their score on a 26-item questionnaire using the Wilcoxon rank-sum test. Results In Trial One, 38 patients completed the no-information arm and 31 completed the in-person discussion arm. Of these 69 patients, 63.8% had twelve years or fewer of formal education and 66.7% had previously been tested for HIV. The mean score on the questionnaire for the in-person discussion arm was higher than for the no information arm (18.7 vs. 13.3, p ≤ 0.0001. In Trial Two, 59 patients completed the in-person discussion and 55 completed the video arms. Of these 114 patients, 50.9% had twelve years or fewer of formal education and 68.4% had previously been tested for HIV. The mean score on the questionnaire for the video arm was similar to the in-person discussion arm (20.0 vs. 19.2; p ≤ 0.33. Conclusion The video "Do you know about rapid HIV testing?" appears to be an acceptable substitute for an in-person pre-test discussion on rapid HIV testing with OraQuick®. In terms of adequately informing ED patients about rapid HIV testing, either form of pre-test information is preferable than for patients

  10. Deciding what information is necessary: do patients with advanced cancer want to know all the details?

    Directory of Open Access Journals (Sweden)

    Russell BJ


    Full Text Available Bethany J Russell, Alicia M WardSouthern Adelaide Palliative Services, Repatriation General Hospital, Daw Park, SA, AustraliaAbstract: Communicating effectively with patients who have advanced cancer is one of the greatest challenges facing physicians today. Whilst guiding the patient through complex diagnostic and staging techniques, treatment regimens and trials, the physician must translate often imprecise or conflicting data into meaningful personalized information that empowers the patient to make decisions about their life and body. This requires understanding, compassion, patience, and skill. This narrative literature review explores current communication practices, information preferences of oncology patients and their families, and communication strategies that may assist in these delicate interactions. Overwhelmingly, the literature suggests that whilst the majority of patients with advanced cancer do want to know their diagnosis and receive detailed prognostic information, this varies not only between individuals but also for a given individual over time. Barriers to the delivery and understanding of information exist on both sides of the physician–patient relationship, and family dynamics are also influential. Despite identifiable trends, the information preferences of a particular patient cannot be reliably predicted by demographic, cultural, or cancer-specific factors. Therefore, our primary recommendation is that the physician regularly asks the patient what information they would like to know, who else should be given the information and be involved in decision making, and how that information should be presented.Keywords: metastatic, communication, prognosis, physician–patient relations

  11. Ontology-based geographic information semantic metadata integration (United States)

    Zhan, Qin; Li, Deren; Zhang, Xia; Xia, Yu


    Metadata is important to facilitate data sharing among Geospatial Information Communities in distributed environment. For unanimous understanding and standard production of metadata annotations, metadata specifications are documented such as Geographic Information Metadata Standard (ISO19115-2003), the Content Standard for Digital Geospatial Metadata (CSDGM), and so on. Though these specifications provide frameworks for description of geographic data, there are two problems which embarrass sufficiently data sharing. One problem is that specifications are lack of domainspecific semantics. Another problem is that specifications can not always solve semantic heterogeneities. To solve the former problem, an ontology-based geographic information metadata extension framework is proposed which can incorporate domain-specific semantics. Besides, for solving the later problem, metadata integration mechanism based on the proposed extension is studied. In this paper, integration of metadata is realized through integration of ontologies. So integration of ontologies is also discussed. By ontology-based geographic information semantic metadata integration, sharing of geographic data is realized more efficiently.

  12. Knowledge-based system for flight information management. Thesis (United States)

    Ricks, Wendell R.


    The use of knowledge-based system (KBS) architectures to manage information on the primary flight display (PFD) of commercial aircraft is described. The PFD information management strategy used tailored the information on the PFD to the tasks the pilot performed. The KBS design and implementation of the task-tailored PFD information management application is described. The knowledge acquisition and subsequent system design of a flight-phase-detection KBS is also described. The flight-phase output of this KBS was used as input to the task-tailored PFD information management KBS. The implementation and integration of this KBS with existing aircraft systems and the other KBS is described. The flight tests are examined of both KBS's, collectively called the Task-Tailored Flight Information Manager (TTFIM), which verified their implementation and integration, and validated the software engineering advantages of the KBS approach in an operational environment.

  13. Internet Health Information Seeking and the Patient-Physician Relationship: A Systematic Review (United States)


    Background With online health information becoming increasingly popular among patients, concerns have been raised about the impact of patients’ Internet health information-seeking behavior on their relationship with physicians. Therefore, it is pertinent to understand the influence of online health information on the patient-physician relationship. Objective Our objective was to systematically review existing research on patients’ Internet health information seeking and its influence on the patient-physician relationship. Methods We systematically searched PubMed and key medical informatics, information systems, and communication science journals covering the period of 2000 to 2015. Empirical articles that were in English were included. We analyzed the content covering themes in 2 broad categories: factors affecting patients’ discussion of online findings during consultations and implications for the patient-physician relationship. Results We identified 18 articles that met the inclusion criteria and the quality requirement for the review. The articles revealed barriers, facilitators, and demographic factors that influence patients’ disclosure of online health information during consultations and the different mechanisms patients use to reveal these findings. Our review also showed the mechanisms in which online information could influence patients’ relationship with their physicians. Conclusions Results of this review contribute to the understanding of the patient-physician relationship of Internet-informed patients. Our main findings show that Internet health information seeking can improve the patient-physician relationship depending on whether the patient discusses the information with the physician and on their prior relationship. As patients have better access to health information through the Internet and expect to be more engaged in health decision making, traditional models of the patient-provider relationship and communication strategies must be

  14. Information Integration Platform for Patient-Centric Healthcare Services: Design, Prototype and Dependability Aspects

    Directory of Open Access Journals (Sweden)

    Yohanes Baptista Dafferianto Trinugroho


    Full Text Available Technology innovations have pushed today’s healthcare sector to an unprecedented new level. Various portable and wearable medical and fitness devices are being sold in the consumer market to provide the self-empowerment of a healthier lifestyle to society. Many vendors provide additional cloud-based services for devices they manufacture, enabling the users to visualize, store and share the gathered information through the Internet. However, most of these services are integrated with the devices in a closed “silo” manner, where the devices can only be used with the provided services. To tackle this issue, an information integration platform (IIP has been developed to support communications between devices and Internet-based services in an event-driven fashion by adopting service-oriented architecture (SOA principles and a publish/subscribe messaging pattern. It follows the “Internet of Things” (IoT idea of connecting everyday objects to various networks and to enable the dissemination of the gathered information to the global information space through the Internet. A patient-centric healthcare service environment is chosen as the target scenario for the deployment of the platform, as this is a domain where IoT can have a direct positive impact on quality of life enhancement. This paper describes the developed platform, with emphasis on dependability aspects, including availability, scalability and security.

  15. Digital Natives Versus Digital Immigrants: Influence of Online Health Information Seeking on the Doctor-Patient Relationship. (United States)

    Haluza, Daniela; Naszay, Marlene; Stockinger, Andreas; Jungwirth, David


    Ubiquitous Internet access currently revolutionizes the way people acquire information by creating a complex, worldwide information network. The impact of Internet use on the doctor-patient relationship is a moving target that varies across sociodemographic strata and nations. To increase scientific knowledge on the patient-Web-physician triangle in Austria, this study reports findings regarding prevailing online health information-seeking behavior and the respective impact on doctor-patient interactions among a nonprobability convenience sample of Internet users. To investigate digital age group-specific influences, we analyzed whether digital natives and digital immigrants differed in their perspectives. The questionnaire-based online survey collected sociodemographic data and online health information-seeking behavior from a sample of 562 respondents (59% females, mean age 37 ± 15 years, 54% digital natives). Most respondents (79%) referred to the Internet to seek health information, making it the most commonly used source for health information, even more prevalent then the doctor. We found similar predictors for using the Internet as a source for health-related information across digital age groups. Thus, the overall generational gap seems to be small among regular Internet users in Austria. However, study participants expressed a rather skeptical attitude toward electronic exchange of health data between health care professionals and patients, as well as toward reliability of online health information. To improve adoption of electronic doctor-patient communication and patient empowerment, public education and awareness programs are required to promote consumer-centered health care provision and patient empowerment.

  16. [Are deaf patients in Germany informed about their legal rights for a sign language interpreter?]. (United States)

    Höcker, J T; Letzel, S; Münster, E


    Deaf citizens are confronted with barriers in a health-care system shaped by hearing people. Therefore the German legislature provides a supply with sign language interpreters at the expense of the health insurances. The present study initially examines in how far the deaf are informed about this and use said interpreters. Traditional surveys are based on spoken and written language and therefore are unsuitable for the target audience. Because of this, a cross-sectional online study was performed using sign language videos and visually oriented answers to allow a barrier-free participation. With a multivariate analysis, factors increasing deaf people's risks not to be informed of the supply with interpreters were identified: Of 841 deaf participants, 31.4% were not informed of their rights. 41.3% have experience with an interpreter at the doctor's and report a mainly trouble-free reimbursement of costs. Young and modestly educated deaf have a higher risk of not being informed of the interpreter supply. Further information is necessary to provide equality of opportunities to deaf patients utilising medical benefits.

  17. Patients and professionals have different views on online patient information about cleft lip and palate (CL/P). (United States)

    van den Bosch, S; Koudstaal, M; Versnel, S; Maal, T; Xi, T; Nelen, W; Bergé, S; Faber, M


    Parents of children with a cleft lip and/or palate (CL/P) and patients with CL/P actively search for online information about CL/P. The quality of this information has not been sufficiently evaluated. The aim of this study was to define quality criteria for online information about CL/P and assess the quality of frequently accessed websites. Patients, parents, and professionals were equally involved in all stages of this study. A literature review was performed to obtain known quality criteria for online information. These criteria were prioritized by patients, parents, and professionals. The most important criteria were used to rate the quality of four websites on CL/P. Forty-two quality items were extracted from the literature. Patients, parents, and professionals agreed on the importance of 16 of these items. New groups of patients, parents, and professionals assessed four websites on CL/P. Although the groups were like-minded in their overall assessment of the quality of the websites, distinct differences emerged between the groups in relation to certain items. This study shows the importance of patient participation in healthcare research, as well as a feasible approach to do so. Involving patients in composing online health information will set different priorities, which is necessary in establishing high quality information.

    Full Text Available Among the most significant values of a business system that contribute to its competitiveness in comparison with others, the leading point and the highest value, second to the human factor, is the information at the company’s disposal, unified in the company’s know how. Unfortunately, the sole awareness of the importance and significance of information is mostly not enough. It is for this reason that this resource is unfairly neglected and is insufficiently used. What results from this situation is that information is mostly unavailable and insufficiently protected. This paper will show one of the possible models of systems for managing information based on principles of adaptability and personalization which aims towards adequate, fast, efficient and secure access to protected information in the company. The subject of this manuscript is to explore the possibilities of modern information and communication technology application in developing information management system based on principles of adaptability and personalization. The main part of this system is the portal for intelligent document management. The solution proposed in the dissertation is based on integration and implementation of services for adaptation in modern document management systems.

  5. Learning based on patient case reviews: an interview study

    Directory of Open Access Journals (Sweden)

    Søndergaard Jens


    Full Text Available Abstract Background Recent theories on adult learning recommend that learning is situated in real-life contexts. Learning is considered a continuous process in which every new experience builds on, and integrates with, previously accumulated experiences. Reviewing and reflecting on patient cases is in line with this learning approach. There has, however, been remarkably little research into how patient cases might be applied in professional education. The purpose of this article is to present family physicians' perceptions of the learning process initiated by reviewing patient cases. Methods Thirteen family physicians, who had all participated in a large project on cancer diagnosis in family practice (the CAP-project, currently carried out at the Research Unit for General Practice, University of Aarhus were interviewed on their experiences of reviewing patient cases. In the CAP-project family physicians (n = 467, 81% in the County of Aarhus (640 000 inhabitants completed 2,212 (83% detailed questionnaires on all newly diagnosed patients with cancer encountered in their practices during a one year period (2004–2005. In order to complete the questionnaire the family physicians were required to perform a systematic case review of each patient: they had to consult their records to provide dates of symptom-presentation, investigations and treatments initiated, and reflect on previous encounters with the patients to give detailed information on his/hers knowledge of the patients' care seeking behaviour, mental health and risk factors. The purpose of this article is to present indebt interview-data on family physicians' perceptions of the learning process initiated by reviewing patient cases, and their evaluations of using patient case reviews as a learning method in family practice. Results The process of reflection initiated by reviewing patient cases enabled family physicians to reconsider their clinical work procedures which potentially supported

  6. Ontology Based Information Retrieval in Semantic Web: A Survey

    Directory of Open Access Journals (Sweden)

    Vishal Jain


    Full Text Available In present age of computers, there are various resources for gathering information related to given query like Radio Stations, Television, Internet and many more. Among them, Internet is considered as major factor for obtaining any information about a given domain. When a user wants to find some information, he/she enters a query and results are produced via hyperlinks linked to various documents available on web. But the information that is retrieved to us may or may not be relevant. This irrelevance is caused due to huge collection of documents available on web. Traditional search engines are based on keyword based searching that is unable to transform raw data into knowledgeable representation data. It is a cumbersome task to extract relevant information from large collection of web documents. These shortcomings have led to the concept of Semantic Web (SW and Ontology into existence. Semantic Web (SW is a well defined portal that helps in extracting relevant information using many Information Retrieval (IR techniques. Current Information Retrieval (IR techniques are not so advanced that they can be able to exploit semantic knowledge within documents and give precise result. The terms, Information Retrieval (IR, Semantic Web (SW and Ontology are used differently but they are interconnected with each other. Information Retrieval (IR technology and Web based Indexing contributes to existence of Semantic Web. Use of Ontology also contributes in building new generation of web- Semantic Web. With the help of ontologies, we can make content of web as it will be markup with the help of Semantic Web documents (SWD’s. Ontology is considered as backbone of Software system.

  7. Trust-based information system architecture for personal wellness. (United States)

    Ruotsalainen, Pekka; Nykänen, Pirkko; Seppälä, Antto; Blobel, Bernd


    Modern eHealth, ubiquitous health and personal wellness systems take place in an unsecure and ubiquitous information space where no predefined trust occurs. This paper presents novel information model and an architecture for trust based privacy management of personal health and wellness information in ubiquitous environment. The architecture enables a person to calculate a dynamic and context-aware trust value for each service provider, and using it to design personal privacy policies for trustworthy use of health and wellness services. For trust calculation a novel set of measurable context-aware and health information-sensitive attributes is developed. The architecture enables a person to manage his or her privacy in ubiquitous environment by formulating context-aware and service provider specific policies. Focus groups and information modelling was used for developing a wellness information model. System analysis method based on sequential steps that enable to combine results of analysis of privacy and trust concerns and the selection of trust and privacy services was used for development of the information system architecture. Its services (e.g. trust calculation, decision support, policy management and policy binding services) and developed attributes enable a person to define situation-aware policies that regulate the way his or her wellness and health information is processed.

    Bergamino, Maurizio; Hamilton, David J; Castelletti, Lara; Barletta, Laura; Castellan, Lucio


    In this study, we describe the development and utilization of a relational database designed to manage the clinical and radiological data of patients with brain tumors. The Brain Tumor Database was implemented using MySQL v.5.0, while the graphical user interface was created using PHP and HTML, thus making it easily accessible through a web browser. This web-based approach allows for multiple institutions to potentially access the database. The BT Database can record brain tumor patient information (e.g. clinical features, anatomical attributes, and radiological characteristics) and be used for clinical and research purposes. Analytic tools to automatically generate statistics and different plots are provided. The BT Database is a free and powerful user-friendly tool with a wide range of possible clinical and research applications in neurology and neurosurgery. The BT Database graphical user interface source code and manual are freely available at

  9. Respiratory clinical guidelines inform ward-based nurses' clinical skills and knowledge required for evidence-based care. (United States)

    Johnson, Alisha M; Smith, Sheree M S


    Respiratory clinical guidelines provide clinicians with evidence-based guidance for practice. Clinical guidelines also provide an opportunity to identify the knowledge and technical and non-technical skills required by respiratory ward-based registered nurses. The aim of this review was to use a systematic process to establish the core technical and non-technical skills and knowledge identified in evidence-based clinical guidelines that enable the care of hospitalised adult respiratory patients. 17 guidelines were identified in our systematic review. The quality assessment demonstrated variability in these guidelines. Common core knowledge and technical and non-technical skills were identified. These include pathophysiology, understanding of physiological measurements and monitoring, education, counselling, and ward and patient management. The knowledge and skills extracted from respiratory clinical guidelines may inform a curriculum for ward-based respiratory nursing to ensure optimal care of adult patients.

  13. Digital multimedia books produced using iBooks Author for pre-operative surgical patient information. (United States)

    Briggs, Matthew; Wilkinson, Caroline; Golash, Aprajay


    Presenting patients with medical information and ensuring informed consent can be difficult due to patients with varying levels of literacy, physical and mental disabilities and spoken languages. Patients obtaining information from external sources, such as the internet, can also be problematic as the information can be irrelevant, inaccurate or misleading. A patient satisfaction study was performed in order to assess the effectiveness of using ebooks in order to communicate pre and post surgical information to neurosurgical patients. 3 digital books were produced using iBooks Author (a free desktop publishing program designed by Apple) including ACDF (anterior cervical discectomy and fusion), lumbar laminectomy and lumbar discectomy. Each book contained written information organised into sections and chapters along with an array of multimedia elements including 3D animations, interactive diagrams, 3D models of anatomy and patient experience videos. 32 volunteer patients were then presented with the digital books via an iPad during their preoperative assessment and then asked to complete a questionnaire. The results demonstrated a demand for this type of digital presentation of medical information and also showed patients no longer felt the need to seek further information from external sources.

    Green, Bonnie L; Saunders, Pamela A; Power, Elizabeth; Dass-Brailsford, Priscilla; Schelbert, Kavitha Bhat; Giller, Esther; Wissow, Larry; Hurtado de Mendoza, Alejandra; Mete, Mihriye


    Trauma exposure predicts mental disorders and health outcomes; yet there is little training of primary care providers about trauma's effects, and how to better interact with trauma survivors. This study adapted a theory-based approach to working with trauma survivors, Risking Connection, into a 6-hour CME course, Trauma-Informed Medical Care (TI-Med), to evaluate its feasibility and preliminary efficacy. We randomized four primary care sites to training or wait-list conditions; PCPs at wait-list sites were trained after reassessment. Primary care providers (PCPs) were Family Medicine residents (n = 17; 2 sites) or community physicians (n = 13; 2 sites). Outcomes reported here comprised a survey of 400 actual patients seen by the PCPs in the study. Patients, mostly minority, completed surveys before or after their provider received training. Patients rated PCPs significantly higher after training on a scale encompassing partnership issues. Breakdowns showed lower partnership scores for those with trauma or posttraumatic stress symptoms. Future studies will need to include more specific trauma-related outcomes. Nevertheless, this training is a promising initial approach to teaching trauma-informed communication skills to PCPs.

  15. Contextual Information Retrieval based on Algorithmic Information Theory and Statistical Outlier Detection

    Martinez, Rafael; Rodriguez, Francisco de Borja; Camacho, David


    The main contribution of this paper is to design an Information Retrieval (IR) technique based on Algorithmic Information Theory (using the Normalized Compression Distance- NCD), statistical techniques (outliers), and novel organization of data base structure. The paper shows how they can be integrated to retrieve information from generic databases using long (text-based) queries. Two important problems are analyzed in the paper. On the one hand, how to detect "false positives" when the distance among the documents is very low and there is actual similarity. On the other hand, we propose a way to structure a document database which similarities distance estimation depends on the length of the selected text. Finally, the experimental evaluations that have been carried out to study previous problems are shown.

    Full Text Available Background The internet can provide evidence-based patient education to overcome time constraints of busy ambulatory practices. Health information prescriptions (HIPs can be effectively integrated into clinic workflow, but compliance to visit health information sites such as MedlinePlus is limited.Objective Compare the efficacy of paper (pHIP and email (eHIP links to deliver HIPs; evaluate patient satisfaction with the HIP process and MedlinePlus information; assess reasons for noncompliance to HIPs.Method Of 948 patients approached at two internal medicine clinics affiliated with an academic medical centre, 592 gave informed consent after meeting the inclusion criteria. In this randomised controlled trial, subjects were randomised to receive pHIP or eHIP for accessing an intermediate website that provided up to five MedlinePlus links for physician-selected HIP conditions. Patients accessing the intermediate website were surveyed by email to assess satisfaction with the health information. Survey non-responders were contacted by telephone to determine the reasons for no response.Results One hundred and eighty-one patients accessed the website, with significantly more ‘filling’ eHIP than pHIP (38% vs 23%; P < 0.001. Most (82% survey respondents found the website information useful, with 77% favouring email for future HIPs delivery. Lack of time, forgot, lost instructions or changed mind were reasons given for not accessing the websites.Conclusions Delivery of MedlinePlus-based HIPs in clinic is more effective using email prescriptions than paper. Satisfaction with the HIP information was high, but overall response was low and deserves further investigation to improve compliance and related outcomes.

    Full Text Available Though Information Retrieval (IR in big data has been an active field of research for past few years; the popularity of the native languages presents a unique challenge in big data information retrieval systems. There is a need to retrieve information which is present in English and display it in the native language for users. This aim of cross language information retrieval is complicated by unique features of the native languages such as: morphology, compound word formations, word spelling variations, ambiguity, word synonym, other language influence and etc. To overcome some of these issues, the native language is modeled using a grammar rule based approach in this work. The advantage of this approach is that the native language is modeled and its unique features are encoded using a set of inference rules. This rule base coupled with the customized ontological system shows considerable potential and is found to show better precision and recall.

  20. Incorporating privileged genetic information for fundus image based glaucoma detection. (United States)

    Duan, Lixin; Xu, Yanwu; Li, Wen; Chen, Lin; Wing, Damon Wing Kee; Wong, Tien Yin; Liu, Jiang


    Visual features extracted from retinal fundus images have been increasingly used for glaucoma detection, as those images are generally easy to acquire. In recent years, genetic researchers have found that some single nucleic polymorphisms (SNPs) play important roles in the manifestation of glaucoma and also show superiority over fundus images for glaucoma detection. In this work, we propose to use the SNPs to form the so-called privileged information and deal with a practical problem where both fundus images and privileged genetic information exist for the training subjects, while the test objects only have fundus images. To solve this problem, we present an effective approach based on the learning using privileged information (LUPI) paradigm to train a predictive model for the image visual features. Extensive experiments demonstrate the usefulness of our approach in incorporating genetic information for fundus image based glaucoma detection.

  1. An Innovative Thinking-Based Intelligent Information Fusion Algorithm

    Directory of Open Access Journals (Sweden)

    Huimin Lu


    Full Text Available This study proposes an intelligent algorithm that can realize information fusion in reference to the relative research achievements in brain cognitive theory and innovative computation. This algorithm treats knowledge as core and information fusion as a knowledge-based innovative thinking process. Furthermore, the five key parts of this algorithm including information sense and perception, memory storage, divergent thinking, convergent thinking, and evaluation system are simulated and modeled. This algorithm fully develops innovative thinking skills of knowledge in information fusion and is a try to converse the abstract conception of brain cognitive science to specific and operable research routes and strategies. Furthermore, the influences of each parameter of this algorithm on algorithm performance are analyzed and compared with those of classical intelligent algorithms trough test. Test results suggest that the algorithm proposed in this study can obtain the optimum problem solution by less target evaluation times, improve optimization effectiveness, and achieve the effective fusion of information.

  2. Symptoms from patients as the primary information source for real-time surveillance. (United States)

    Johansen, Monika Alise; Johnsen, Jan-Are Kolset; Shrestha, Neema; Bellika, Johan Gustav


    The aim of this study was to identify whether patients could become the primary data source for symptom based real-time surveillance. The study investigated people's attitude towards providing symptom information electronically before a consultation, and how they preferred to carry out the reporting. Data was collected by distributing questionnaires to 83 respondents. The results show that 96 percent of the respondents had a positive attitude towards providing information about their symptoms to the GP's office as soon as possible after falling ill. Over half of the respondents preferred to use e-mail or a web-interface to perform this task. Eighty four percent were willing to have their symptom data stored in their EPR and 76 percent agreed that the GP might access and present the symptoms together with the prevalence of matching diseases in order to assist the diagnostic process during the next consultation. This study indicates that patients could become the primary data source for symptom based surveillance in countries with high e-readiness.

  4. Validity and reliability testing of two instruments to measure breast cancer patients' concerns and information needs relating to radiation therapy

    Directory of Open Access Journals (Sweden)

    Kristjanson Linda J


    Full Text Available Abstract Background It is difficult to determine the most effective approach to patient education or tailor education interventions for patients in radiotherapy without tools that assess patients' specific radiation therapy information needs and concerns. Therefore, the aim of this study was to develop psychometrically sound tools to adequately determine the concerns and information needs of cancer patients during radiation therapy. Patients and Methods Two tools were developed to (1 determine patients concerns about radiation therapy (RT Concerns Scale and (2 ascertain patient's information needs at different time point during their radiation therapy (RT Information Needs Scale. Tools were based on previous research by the authors, published literature on breast cancer and radiation therapy and information behaviour research. Thirty-one breast cancer patients completed the questionnaire on one occasion and thirty participants completed the questionnaire on a second occasion to facilitate test-retest reliability. One participant's responses were removed from the analysis. Results were analysed for content validity, internal consistency and stability over time. Results Both tools demonstrated high internal consistency and adequate stability over time. The nine items in the RT Concerns Scale were retained because they met all pre-set psychometric criteria. Two items were deleted from the RT Information Needs Scale because they did not meet content validity criteria and did not achieve pre-specified criteria for internal consistency. This tool now contains 22 items. Conclusion This paper provides preliminary data suggesting that the two tools presented are reliable and valid and would be suitable for use in trials or in the clinical setting.

    Urban land utilization plays an important role in city development. We establish the "Urban Land Information System based on GIS" in order to inspect urban land structure and utilize a model automatically. A series of codes abstracted from urban land sustainable utilization significance are used as measures in land inspection. GIS tools combined with "Urban Land Information System" make visible codes calculations and statistical results possible. Useful mathematic methods are cited to analyze the degree urban land sustainable and optimize land structure. By scientific system analysis, relationships among modules and system structure are illustrated clearly. As a result this study has drawn out the "Urban Land Information System" model.

  9. [Relations between health information systems and patient safety]. (United States)

    Nøhr, Christian


    Health information systems have the potential to reduce medical errors, and indeed many studies have shown a significant reduction. However, if the systems are not designed and implemented properly, there is evidence that suggest that new types of errors will arise--i.e., technology-induced errors. Health information systems will need to undergo a more rigorous evaluation. Usability evaluation and simulation test with humans in the loop can help to detect and prevent technology-induced errors before they are deployed in real health-care settings.

  10. Leveraging on information technology to enhance patient care: a doctor's perspective of implementation in a Singapore academic hospital. (United States)

    Ong, B K C


    Information technology (IT) can improve the safety of patient care by minimising prescribing errors and organising patient-specific information from diverse databases. Apart from legibility, prescribing safety is enhanced as online access to databases carrying patient drug history, scientific drug information and guideline reference, and patient-specific information is available to the physician. Such specific information includes discharge summaries, surgical procedure summaries, laboratory data and investigation reports. In addition, decision support and prompts can be built in to catch errant orders. For such system implementations to work, the IT backbone must be fast, reliable and simple to use. End-user involvement and ownership of all aspects of development are key to a usable system. However, the hospital leadership must also have the will to mandate and support these development efforts. With such support, the design and implementation team can then map out a strategy where the greatest impact is achieved in both safety and enhanced information flow. The system should not be considered a finished work, but a continual work in progress. The National University Hospital's continuously updated Computerised Patient Support System (CPSS) is an example of an IT system designed to manage information and facilitate prescribing. It is a client-server based, one-point ordering and information access portal for doctors that has widespread adoption for drug prescription at outpatient and discharge medication usage areas. This system has built in safety prompts and rudimentary decision support. It has also become the choice means of accessing patient-related databases that impact on diagnoses and management.

  11. Is information always a good thing? Helping patients make "good" decisions. (United States)

    Ubel, Peter A


    In most cases, patient preferences are crucial in making good health care decisions. For example, choices between chemotherapy and radiation treatment usually hinge on trade-offs that only patients can decide about. In recognition of the importance of patient preferences in clinical decisions, health services researchers have begun developing decision aids to help patients understand complex medical information. But these decision aids might lead to "bad choices"-choices that are inconsistent with people's stated preferences. In this paper, the author provides examples of how people make inconsistent medical decisions, and briefly discusses future directions for exploring ways of structuring information so that patients are less likely to make inconsistent choices.

    Full Text Available This article examines goals of standards-based reform in education and ways in which developments in information technology have facilitated those goals. Since standards-based reform is a rather general concept, I begin by developing a more specific formulation which I refer to as the “standards-based instruction and assessment” model. Developments in information technology over the last fifteen years have contributed in important ways to the goals of standards-based reform at the policy level, but difficult organizational and technical challenges still have to be overcome to realize more fully the goal of standards-based instruction and assessment in instructional management and practice within schools and classrooms.

  17. Security of electronic medical information and patient privacy: what you need to know. (United States)

    Andriole, Katherine P


    The responsibility that physicians have to protect their patients from harm extends to protecting the privacy and confidentiality of patient health information including that contained within radiological images. The intent of HIPAA and subsequent HIPAA Privacy and Security Rules is to keep patients' private information confidential while allowing providers access to and maintaining the integrity of relevant information needed to provide care. Failure to comply with electronic protected health information (ePHI) regulations could result in financial or criminal penalties or both. Protected health information refers to anything that can reasonably be used to identify a patient (eg, name, age, date of birth, social security number, radiology examination accession number). The basic tools and techniques used to maintain medical information security and patient privacy described in this article include physical safeguards such as computer device isolation and data backup, technical safeguards such as firewalls and secure transmission modes, and administrative safeguards including documentation of security policies, training of staff, and audit tracking through system logs. Other important concepts related to privacy and security are explained, including user authentication, authorization, availability, confidentiality, data integrity, and nonrepudiation. Patient privacy and security of medical information are critical elements in today's electronic health care environment. Radiology has led the way in adopting digital systems to make possible the availability of medical information anywhere anytime, and in identifying and working to eliminate any risks to patients.

    Yamamoto, Michiko; Doi, Hirohisa; Furukawa, Aya


    Patients and consumers have desired high quality drug information in their pharmacotherapy, and are entitled to receive it. It is desirable that the information should be aimed at shared decision-making between patients and healthcare professionals about medications. The quality of drug information available to patients should also be assured. With an aim to improve the quality of "Drug Guide for Patients", we investigated Patient Information Leaflets (PILs) which are approved by the Medicines and Healthcare Products Regulatory Agency (MHRA) in the United Kingdom (UK) with regard to the criteria of development and user testing for assuring the quality of the PILs. In the European Union (EU), these are called Package Leaflets (PLs). PILs have been a legal requirement in the UK since 1999 for all medications. The user testing of PILs has been implemented as evidence since 2005 so that people can rely on the information provided in the leaflet. Execution of PILs which follow the guidance of the user testing, according to the guidance of this user testing, would reflect the views of patients. Here, we introduce the development process and implementation of user testing of PILs. In terms of readability, accessibility and understandability of drug information for patients, we need to discuss involving the public in decisions on how its quality should be assured and how it can be made easily be comprehensible for patients, in order to make effective use of "Drug Guide for Patients" in the future in Japan.

    张磊; 杜小勇; 王珊


    The information dissemination model is becoming increasingly important inwide-area information systems. In this model, a user subscribes to an information disseminationservice by submitting profiles that describe his interests. There have been several simple kindsof information dissemination services on the Internet such as mailing list, but the problemis that it provides a crude granularity of interest matching. A user whose information needdoes not exactly match certain lists will either receive too many irrelevant or too few relevantmessages. This paper presents a personalized information dissemination model based on How-Net, which uses a Concept Network-Views (CN-V) model to support information filtering, user'sinterests modeling and information recommendation. A Concept Network is constructed uponthe user's profiles and the content of documents, which describes concepts and their relationsin the content and assigns different weights to these concepts. Usually the Concept Network isnot well arranged, from which it is hard to find some useful relations, so several views from areextracted it to represent the important relations explicitly.

    Bakhshi, Rena; Fokkink, Wan; van Steen, Maarten


    We present an analytical framework for gossip protocols based on the pairwise information exchange between interacting nodes. This framework allows for studying the impact of protocol parameters on the performance of the protocol. Previously, gossip-based information dissemination protocols have been analyzed under the assumption of perfect, lossless communication channels. We extend our framework for the analysis of networks with lossy channels. We show how the presence of message loss, coupled with specific topology configurations,impacts the expected behavior of the protocol. We validate the obtained models against simulations for two protocols.

  6. The formal-informal patient payment mix in European countries. Governance, economics, culture or all of these? (United States)

    Tambor, Marzena; Pavlova, Milena; Golinowska, Stanisława; Sowada, Christoph; Groot, Wim


    Cost-sharing for health care is high on the policy agenda in many European countries that struggle with deficits in their public budget. However, such policy often meets with public opposition, which might delay or even prevent its implementation. Increased reliance on patient payments may also have adverse equity effects, especially in countries where informal patient payments are widespread. The factors which might influence the presence of both, formal and informal payments can be found in economic, governance and cultural differences between countries. The aim of this paper is to review the formal-informal payment mix in Europe and to outline factors associated with this mix. We use quantitative analyses of macro-data for 35 European countries and a qualitative description of selected country experiences. The results suggest that the presence of obligatory cost-sharing for health care services is associated with governance factors, while informal patient payments are a multi-cause phenomenon. A consensus-based policy, supported by evidence and stakeholders' engagement, might contribute to a more sustainable patient payment policy. In some European countries, the implementation of cost-sharing requires policy actions to reduce other patient payment obligations, including measures to eliminate informal payments.

  7. Enabling task-based information prioritization via semantic web encodings (United States)

    Michaelis, James R.


    Modern Soldiers rely upon accurate and actionable information technology to achieve mission objectives. While increasingly rich sensor networks for Areas of Operation (AO) can offer many directions for aiding Soldiers, limitations are imposed by current tactical edge systems on the rate that content can be transmitted. Furthermore, mission tasks will often require very specific sets of information which may easily be drowned out by other content sources. Prior research on Quality and Value of Information (QoI/VoI) has aimed to define ways to prioritize information objects based on their intrinsic attributes (QoI) and perceived value to a consumer (VoI). As part of this effort, established ranking approaches for obtaining Subject Matter Expert (SME) recommendations, such as the Analytic Hierarchy Process (AHP) have been considered. However, limited work has been done to tie Soldier context - such as descriptions of their mission and tasks - back to intrinsic attributes of information objects. As a first step toward addressing the above challenges, this work introduces an ontology-backed approach - rooted in Semantic Web publication practices - for expressing both AHP decision hierarchies and corresponding SME feedback. Following a short discussion on related QoI/VoI research, an ontology-based data structure is introduced for supporting evaluation of Information Objects, using AHP rankings designed to facilitate information object prioritization. Consistent with alternate AHP approaches, prioritization in this approach is based on pairwise comparisons between Information Objects with respect to established criteria, as well as on pairwise comparison of the criteria to assess their relative importance. The paper concludes with a discussion of both ongoing and future work.

    Martinez, Gonzalo; Pachepsky, Yakov; Pan, Feng; Wagener, Thorsten; Nicholson, Thomas


    The accuracy-based model performance metrics not necessarily reflect the qualitative correspondence between simulated and measured streamflow time series. The objective of this work was to use the information theory-based metrics to see whether they can be used as complementary tool for hydrologic model evaluation and selection. We simulated 10-year streamflow time series in five watersheds located in Texas, North Carolina, Mississippi, and West Virginia. Eight model of different complexity were applied. The information-theory based metrics were obtained after representing the time series as strings of symbols where different symbols corresponded to different quantiles of the probability distribution of streamflow. The symbol alphabet was used. Three metrics were computed for those strings - mean information gain that measures the randomness of the signal, effective measure complexity that characterizes predictability and fluctuation complexity that characterizes the presence of a pattern in the signal. The observed streamflow time series has smaller information content and larger complexity metrics than the precipitation time series. Watersheds served as information filters and and streamflow time series were less random and more complex than the ones of precipitation. This is reflected the fact that the watershed acts as the information filter in the hydrologic conversion process from precipitation to streamflow. The Nash Sutcliffe efficiency metric increased as the complexity of models increased, but in many cases several model had this efficiency values not statistically significant from each other. In such cases, ranking models by the closeness of the information-theory based parameters in simulated and measured streamflow time series can provide an additional criterion for the evaluation of hydrologic model performance.

    Prieto, Claudia I; Palau, María J; Martina, Pablo; Achiary, Carlos; Achiary, Andrés; Bettiol, Marisa; Montanaro, Patricia; Cazzola, María L; Leguizamón, Mariana; Massillo, Cintia; Figoli, Cecilia; Valeiras, Brenda; Perez, Silvia; Rentería, Fernando; Diez, Graciela; Yantorno, Osvaldo M; Bosch, Alejandra


    The epidemiological and clinical management of cystic fibrosis (CF) patients suffering from acute pulmonary exacerbations or chronic lung infections demands continuous updating of medical and microbiological processes associated with the constant evolution of pathogens during host colonization. In order to monitor the dynamics of these processes, it is essential to have expert systems capable of storing and subsequently extracting the information generated from different studies of the patients and microorganisms isolated from them. In this work we have designed and developed an on-line database based on an information system that allows to store, manage and visualize data from clinical studies and microbiological analysis of bacteria obtained from the respiratory tract of patients suffering from cystic fibrosis. The information system, named Cystic Fibrosis Cloud database is available on the site and is composed of a main database and a web-based interface, which uses Servoy's product architecture based on Java technology. Although the CFC database system can be implemented as a local program for private use in CF centers, it can also be used, updated and shared by different users who can access the stored information in a systematic, practical and safe manner. The implementation of the CFC database could have a significant impact on the monitoring of respiratory infections, the prevention of exacerbations, the detection of emerging organisms, and the adequacy of control strategies for lung infections in CF patients.

  13. The Limits of Informed Consent for an Overwhelmed Patient: Clinicians' Role in Protecting Patients and Preventing Overwhelm. (United States)

    Bester, Johan; Cole, Cristie M; Kodish, Eric


    In this paper, we examine the limits of informed consent with particular focus on ways in which various factors can overwhelm decision-making capacity. We introduce overwhelm as a phenomenon commonly experienced by patients in clinical settings and distinguish between emotional overwhelm and informational overload. We argue that in these situations, a clinician's primary duty is prevention of harm and suggest ways in which clinicians can discharge this obligation. To illustrate our argument, we consider the clinical application of genetic sequencing testing, which involves scientific and technical information that can compromise the understanding and decisional capacity of most patients. Finally, we consider and rebut objections that this could lead to paternalism.

  14. Measuring and improving patient safety through health information technology: The Health IT Safety Framework. (United States)

    Singh, Hardeep; Sittig, Dean F


    Health information technology (health IT) has potential to improve patient safety but its implementation and use has led to unintended consequences and new safety concerns. A key challenge to improving safety in health IT-enabled healthcare systems is to develop valid, feasible strategies to measure safety concerns at the intersection of health IT and patient safety. In response to the fundamental conceptual and methodological gaps related to both defining and measuring health IT-related patient safety, we propose a new framework, the Health IT Safety (HITS) measurement framework, to provide a conceptual foundation for health IT-related patient safety measurement, monitoring, and improvement. The HITS framework follows both Continuous Quality Improvement (CQI) and sociotechnical approaches and calls for new measures and measurement activities to address safety concerns in three related domains: 1) concerns that are unique and specific to technology (e.g., to address unsafe health IT related to unavailable or malfunctioning hardware or software); 2) concerns created by the failure to use health IT appropriately or by misuse of health IT (e.g. to reduce nuisance alerts in the electronic health record (EHR)), and 3) the use of health IT to monitor risks, health care processes and outcomes and identify potential safety concerns before they can harm patients (e.g. use EHR-based algorithms to identify patients at risk for medication errors or care delays). The framework proposes to integrate both retrospective and prospective measurement of HIT safety with an organization's existing clinical risk management and safety programs. It aims to facilitate organizational learning, comprehensive 360 degree assessment of HIT safety that includes vendor involvement, refinement of measurement tools and strategies, and shared responsibility to identify problems and implement solutions. A long term framework goal is to enable rigorous measurement that helps achieve the safety

  15. Balancing confidentiality and the information provided to families of patients in primary care (United States)

    Perez-Carceles, M; Pereniguez, J; Osuna, E; Luna, A


    Objectives: This study aimed to describe family doctors' attitudes to confidentiality and providing patient information to relatives as well as their justifications for sharing information. Method: A descriptive postal questionnaire was self-administered by family doctors. Results: Of 227 doctors, 95.1% provided information to a patient's family and over a third (35%) disclosed information to others without prior patient consent. Conclusions: The findings reveal that family doctors should pay more attention to their patients' rights to information, privacy, and confidentiality, and reflect very carefully on the fine balance between this and the occasional need for the support and collaboration of family members in delivery of care. Emphasis should be placed on ethics and legal problems during undergraduate education and in-service training of doctors. PMID:16131555

  16. The Perception and Practice of Evidence Based Library and Information Practice

    Directory of Open Access Journals (Sweden)

    Vahideh Zarea Gavgani


    Full Text Available Objective – Evidence based library and information services help to link best evidence with decision making in library practice. Current library and information science practice operates in both a knowledge and evidence‐based environment. Health service librarians provide information services in an evidence based health care context to improve patient care. But the evidence based practice movement has influenced many fields of human knowledge, including librarianship. Therefore, this study seeks to answer the following questions: 1 What are the perceptions of Iranian medical librarians regarding the use of an evidence based approach in their decision making processes? 2 Do Iranian medical librarians apply an evidence based approach in their professional work? 3 How do Iranian medical librarians practice an evidence based approach? 4 What are the barriers and limitations for Iranian medical librarians who engage in evidence based library and information practice (EBLIP?Methods – This study utilized a survey to discover medical librarians’ attitudes and perceptions towards the use of an evidence based approach to library practice in Iran. Data was collected using a structured questionnaire to identify medical librarians’ attitudes toward EBLIP.Results – The findings of the study indicate that Iranian medical librarians are aware of EBLIP and that they utilize an evidence based approach towards their LIS work. They practice the five steps of an evidence based answering cycle in formulating, locating, assessing, applying, and redefining questions. However, they have less knowledge about levels of evidence, research methodologies, and critical appraisal. Conclusions – Medical librarians in Iran are familiar with the concept of an evidence based approach. More training is needed in some elements of evidence based practice to improve their approach to evidence based library and information practice.

  17. Using health information technology to manage a patient population in accountable care organizations. (United States)

    Wu, Frances M; Rundall, Thomas G; Shortell, Stephen M; Bloom, Joan R


    Purpose - The purpose of this paper is to describe the current landscape of health information technology (HIT) in early accountable care organizations (ACOs), the different strategies ACOs are using to develop HIT-based capabilities, and how ACOs are using these capabilities within their care management processes to advance health outcomes for their patient population. Design/methodology/approach - Mixed methods study pairing data from a cross-sectional National Survey of ACOs with in-depth, semi-structured interviews with leaders from 11 ACOs (both completed in 2013). Findings - Early ACOs vary widely in their electronic health record, data integration, and analytic capabilities. The most common HIT capability was drug-drug and drug-allergy interaction checks, with 53.2 percent of respondents reporting that the ACO possessed the capability to a high degree. Outpatient and inpatient data integration was the least common HIT capability (8.1 percent). In the interviews, ACO leaders commented on different HIT development strategies to gain a more comprehensive picture of patient needs and service utilization. ACOs realize the necessity for robust data analytics, and are exploring a variety of approaches to achieve it. Research limitations/implications - Data are self-reported. The qualitative portion was based on interviews with 11 ACOs, limiting generalizability to the universe of ACOs but allowing for a range of responses. Practical implications - ACOs are challenged with the development of sophisticated HIT infrastructure. They may benefit from targeted assistance and incentives to implement health information exchanges with other providers to promote more coordinated care management for their patient population. Originality/value - Using new empirical data, this study increases understanding of the extent of ACOs' current and developing HIT capabilities to support ongoing care management.

  19. An information based approach to improving overhead imagery collection (United States)

    Sourwine, Matthew J.; Hintz, Kenneth J.


    Recent growth in commercial imaging satellite development has resulted in a complex and diverse set of systems. To simplify this environment for both customer and vendor, an information based sensor management model was built to integrate tasking and scheduling systems. By establishing a relationship between image quality and information, tasking by NIIRS can be utilized to measure the customer's required information content. Focused on a reduction in uncertainty about a target of interest, the sensor manager finds the best sensors to complete the task given the active suite of imaging sensors' functions. This is done through determination of which satellite will meet customer information and timeliness requirements with low likelihood of interference at the highest rate of return.

  20. On long-only information-based portfolio diversification framework (United States)

    Santos, Raphael A.; Takada, Hellinton H.


    Using the concepts from information theory, it is possible to improve the traditional frameworks for long-only asset allocation. In modern portfolio theory, the investor has two basic procedures: the choice of a portfolio that maximizes its risk-adjusted excess return or the mixed allocation between the maximum Sharpe portfolio and the risk-free asset. In the literature, the first procedure was already addressed using information theory. One contribution of this paper is the consideration of the second procedure in the information theory context. The performance of these approaches was compared with three traditional asset allocation methodologies: the Markowitz's mean-variance, the resampled mean-variance and the equally weighted portfolio. Using simulated and real data, the information theory-based methodologies were verified to be more robust when dealing with the estimation errors.

  3. Information distribution in distributed microprocessor based flight control systems (United States)

    Montgomery, R. C.; Lee, P. S.


    This paper presents an optimal control theory that accounts for variable time intervals in the information distribution to control effectors in a distributed microprocessor based flight control system. The theory is developed using a linear process model for the aircraft dynamics and the information distribution process is modeled as a variable time increment process where, at the time that information is supplied to the control effectors, the control effectors know the time of the next information update only in a stochastic sense. An optimal control problem is formulated and solved that provides the control law that minimizes the expected value of a quadratic cost function. An example is presented where the theory is applied to the control of the longitudinal motions of the F8-DFBW aircraft. Theoretical and simulation results indicate that, for the example problem, the optimal cost obtained using a variable time increment Markov information update process where the control effectors know only the past information update intervals and the Markov transition mechanism is almost identical to that obtained using a known uniform information update interval.

    Fei Wang; Mathini Sellathurai; Weigang Liu; Jiangjiang Zhou


    Radar radio frequency (RF) stealth is very important in electronic war (EW), and waveform design and selection. Existing evaluation rules of radar RF stealth include too many parameters of radar and interceptors, such as Schleher interception factor, which makes it difficult to evaluate radar RF stealth technologies if interceptor parameters are unknown. In communication, security capacity has been presented to describe the possible ability to communicate in complete security. Since the essential of the secu-rity capacity is to have the interceptor get none valued information from the emitter, this paper is proposed to study security infor-mation factors taking advantage of mutual information to evaluate radar RF stealth under some conditions. Through analyzing mutual information obtained by the radar and the interceptor, this paper defines the security information factor with and without cooperative jamming. Furthermore, this paper deduces the ratio of the match filter to the match incoherent filter and discuss mutual information received by the interceptor. Numerical simulations il ustrate radar RF stealth effects based on the security information factor concept under different conditions.

    Full Text Available In this paper VQ (Vector Quantization based on information theoretic learning is investigated for the task of text-independent speaker verification. A novel VQ method based on the IT (Information Theoretic principles is used for the task of speaker verification and compared with two classical VQ approaches: the K-means algorithm and the LBG (Linde Buzo Gray algorithm. The paper provides a theoretical background of the vector quantization techniques, which is followed by experimental results illustrating their performance. The results demonstrated that the ITVQ (Information Theoretic Vector Quantization provided the best performance in terms of classification rates, EER (Equal Error Rates and the MSE (Mean Squared Error compare to Kmeans and the LBG algorithms. The outstanding performance of the ITVQ algorithm can be attributed to the fact that the IT criteria used by this algorithm provide superior matching between distribution of the original data vectors and the codewords.

  6. Information Gain Based Dimensionality Selection for Classifying Text Documents

    Energy Technology Data Exchange (ETDEWEB)

    Dumidu Wijayasekara; Milos Manic; Miles McQueen


    Selecting the optimal dimensions for various knowledge extraction applications is an essential component of data mining. Dimensionality selection techniques are utilized in classification applications to increase the classification accuracy and reduce the computational complexity. In text classification, where the dimensionality of the dataset is extremely high, dimensionality selection is even more important. This paper presents a novel, genetic algorithm based methodology, for dimensionality selection in text mining applications that utilizes information gain. The presented methodology uses information gain of each dimension to change the mutation probability of chromosomes dynamically. Since the information gain is calculated a priori, the computational complexity is not affected. The presented method was tested on a specific text classification problem and compared with conventional genetic algorithm based dimensionality selection. The results show an improvement of 3% in the true positives and 1.6% in the true negatives over conventional dimensionality selection methods.

  7. An Exploratory Study on the Information Needs of Prostate Cancer Patients and Their Partners. (United States)

    Kassianos, Angelos P; Raats, Monique M; Gage, Heather


    The aim of this study is to explore the information needs of men with prostate cancer and their partners retrospectively at various points in the treatment process. An online questionnaire was used to collect information from men with prostate cancer and their partners about information needs, and when these developed. Readers of a Prostate Care Cookbook and members of a Prostate Cancer Charity were invited to participate: 73 men with prostate cancer and 25 partners completed the questionnaire. Responses showed that participants develop their information needs close to diagnosis. Less educated men with prostate cancer and partners developed their needs closer to the time after diagnosis than those with higher education. Partners develop an interest on information related to treatment and interaction earlier than patients. Patients prioritised treatment and disease-specific information. Patients and partners differ in how their information needs develop. Medical information is prioritized by patients as opposed to practical information by partners. Health care provision can be tailored to meet the different needs of prostate cancer patients and their partners at different times in the treatment process.

  17. Virtual World-Based Information Security Learning: Design and Evaluation

    Directory of Open Access Journals (Sweden)

    Ryoo, Jungwoo


    Full Text Available There has been a growing interest and enthusiasm for the application of virtual worlds in learning and training. This research proposes a design framework of a virtual world-based learning environment that integrates two unique features of the virtual world technology, immersion and interactivity, with an instructional strategy that promotes self-regulatory learning. We demonstrate the usefulness and assess the effectiveness of our design in the context of information security learning. In particular, the information security learning module implemented in Second Life was incorporated into an Introduction to Information Security course. Data from pre- and post- learning surveys were used to evaluate the effectiveness of the learning module. Overall, the results strongly suggest that the virtual world-based learning environment enhances information security learning, thus supporting the effectiveness of the proposed design framework. Additional results suggest that learner traits have an important influence on learning outcomes through perceived enjoyment. The study offers useful design and implementation guidelines for organizations and universities to develop a virtual world-based learning environment. It also represents an initial step towards the design and explanation theories of virtual world-based learning environments.

  18. Application of Information Visualization Techniques in Representing Patients' Temporal Personal History Data (United States)

    Noah, Shahrul Azman; Yaakob, Suraya; Shahar, Suzana

    The anthropometries and nutrients records of patients are usually vast in quantity, complex and exhibit temporal features. Therefore, the information acceptance among users will become blur and give cognitive burden if such data is not displayed using effective techniques. The aim of this study is to apply, use and evaluate Information Visualization (IV) techniques for displaying the Personal History Data (PHD) of patients for dietitians during counseling sessions. Since PHD values change consistently with the counseling session, our implementation mainly focused on quantitative temporal data such as Body Mass Index (BMI), blood pressure and blood glucose readings. This data is mapped into orientation circle type of visual representation, whereas data about medicinal and supplement intake are mapped into timeline segment which is based on the thickness of lines as well as the colors. A usability testing has been conducted among dietitians at Faculty of Allied Health Sciences, UKM. The result of the testing has shown that the use of visual representations capable of summarising complex data which ease the dietitian task of checking the PHD.

  19. [Development of integrated clinical abilities by simulated patient assisted problem-based learning tutorial]. (United States)

    Norose, Takahiko


    In Hokkaido Pharmaceutical University, problem-based learning (PBL) has been introduced as a part of the laboratory and practice curriculum for all school years to promote active learning skills and enhance students' problem-solving ability. The PBL program at our school has been developed using a tutorial study based on scenarios and learning strategies, such as experiments and/or standardized patients (SPs) and role-playing, according to students' developmental stage and learning objectives. The course "Practice VIII/Principles of Clinical Communication" for the fifth-grade students is an example of the new PBL program to improve students' clinical communication skills and ability to design a care plan for patients. We divided 196 students into 49 groups (each group had 4 members). We used the large-class PBL model, in which the students had discussions with several facilitators. The students were presented with a patient-case scenario, in which they were first provided with a brief background of the patient. Afterward, students interviewed SPs to obtain detailed information, based on which a care plan was designed for each patient. Students role-played with SPs as a part of patient support, consulted using the patient care plan, and made Subjective information, Objective information, Assessment, and Plan (SOAP) notes at the end. Some students commented that the PBL program was very helpful in understanding how to design a patient care plan and that they understood the importance of communication in obtaining information for designing a patient care plan.

  1. [The informed patient and medical knowledge: a virtual ethnography study of Facebook communities of the infirm]. (United States)

    Pereira Neto, André; Barbosa, Letícia; Silva, Adriano da; Dantas, Monica Lucia Gomes


    Today's world has brought the emergence of the "informed patient:" someone who becomes well-informed about his or her medical condition through extensive research and information-sharing on the Internet. The article explores the following question: Do informed patients foster citizen empowerment or do they expand the command of existing biomedical knowledge? Using virtual ethnography, an exploratory study was conducted on three online Facebook groups of people with diabetes, hepatitis C, and Aids. Findings suggest points of tension between Facebook members and their healthcare providers. It may be that the empowerment fostered by the Internet and the validity of current medical knowledge are not mutually exclusive.

  3. Physicians' perception of the effects of Internet health information on the doctor-patient relationship. (United States)

    Kim, Jeongeun; Kim, Sukwha


    The objective of the study was to determine physician's perception of the effects of health information on the internet on doctor-patient relationship. Online questionnaire with 25 items were sent to the Korean physicians' e-mail, and 493 replied. Eight-nine percent of the Korean physicians reported they had experiences of patients discussing the Internet health information. They perceived that Internet health information may enhance the patients' knowledge about their health. However, they perceived that Internet health information may have variety of negative effects such as; heightening the cost of health care by adopting the inappropriate health service utilisation (56.2%); making the patients over-concerned about their health (74.5%); damaging the time efficiency of the visit (60.9%). The physicians deemed that those informations were not relevant to the patients' health condition (42.7%), and even were not correct (39.0%). Physicians' perception of the Internet health information is both positive and negative, and they perceive the overall effects on doctor-patient relationship as neutral. More physicians think the discussion could be the hindrance on the efficient time management during their visits. However, more physicians have positive perception of the effects on the quality of care and patient outcomes which is promising.

  4. Utility-based early modulation of processing distracting stimulus information. (United States)

    Wendt, Mike; Luna-Rodriguez, Aquiles; Jacobsen, Thomas


    Humans are selective information processors who efficiently prevent goal-inappropriate stimulus information to gain control over their actions. Nonetheless, stimuli, which are both unnecessary for solving a current task and liable to cue an incorrect response (i.e., "distractors"), frequently modulate task performance, even when consistently paired with a physical feature that makes them easily discernible from target stimuli. Current models of cognitive control assume adjustment of the processing of distractor information based on the overall distractor utility (e.g., predictive value regarding the appropriate response, likelihood to elicit conflict with target processing). Although studies on distractor interference have supported the notion of utility-based processing adjustment, previous evidence is inconclusive regarding the specificity of this adjustment for distractor information and the stage(s) of processing affected. To assess the processing of distractors during sensory-perceptual phases we applied EEG recording in a stimulus identification task, involving successive distractor-target presentation, and manipulated the overall distractor utility. Behavioral measures replicated previously found utility modulations of distractor interference. Crucially, distractor-evoked visual potentials (i.e., posterior N1) were more pronounced in high-utility than low-utility conditions. This effect generalized to distractors unrelated to the utility manipulation, providing evidence for item-unspecific adjustment of early distractor processing to the experienced utility of distractor information.

  5. On the security of a dynamic ID-based authentication scheme for telecare medical information systems. (United States)

    Lin, Han-Yu


    Telecare medical information systems (TMISs) are increasingly popular technologies for healthcare applications. Using TMISs, physicians and caregivers can monitor the vital signs of patients remotely. Since the database of TMISs stores patients' electronic medical records (EMRs), only authorized users should be granted the access to this information for the privacy concern. To keep the user anonymity, recently, Chen et al. proposed a dynamic ID-based authentication scheme for telecare medical information system. They claimed that their scheme is more secure and robust for use in a TMIS. However, we will demonstrate that their scheme fails to satisfy the user anonymity due to the dictionary attacks. It is also possible to derive a user password in case of smart card loss attacks. Additionally, an improved scheme eliminating these weaknesses is also presented.

  6. Managing geometric information with a data base management system (United States)

    Dube, R. P.


    The strategies for managing computer based geometry are described. The computer model of geometry is the basis for communication, manipulation, and analysis of shape information. The research on integrated programs for aerospace-vehicle design (IPAD) focuses on the use of data base management system (DBMS) technology to manage engineering/manufacturing data. The objectives of IPAD is to develop a computer based engineering complex which automates the storage, management, protection, and retrieval of engineering data. In particular, this facility must manage geometry information as well as associated data. The approach taken on the IPAD project to achieve this objective is discussed. Geometry management in current systems and the approach taken in the early IPAD prototypes are examined.

  7. Least Dependent Component Analysis Based on Mutual Information

    CERN Document Server

    Stögbauer, H; Astakhov, S A; Grassberger, P; St\\"ogbauer, Harald; Kraskov, Alexander; Astakhov, Sergey A.; Grassberger, Peter


    We propose to use precise estimators of mutual information (MI) to find least dependent components in a linearly mixed signal. On the one hand this seems to lead to better blind source separation than with any other presently available algorithm. On the other hand it has the advantage, compared to other implementations of `independent' component analysis (ICA) some of which are based on crude approximations for MI, that the numerical values of the MI can be used for: (i) estimating residual dependencies between the output components; (ii) estimating the reliability of the output, by comparing the pairwise MIs with those of re-mixed components; (iii) clustering the output according to the residual interdependencies. For the MI estimator we use a recently proposed k-nearest neighbor based algorithm. For time sequences we combine this with delay embedding, in order to take into account non-trivial time correlations. After several tests with artificial data, we apply the resulting MILCA (Mutual Information based ...

    The 'Individualized Therapy for Relapsed Malignancies in Childhood' (INFORM) precision medicine study is a nationwide German program for children with high-risk relapsed/refractory malignancies, which aims to identify therapeutic targets on an individualised basis. In a pilot phase, reported here, we developed the logistical and analytical pipelines necessary for rapid and comprehensive molecular profiling in a clinical setting. Fifty-seven patients from 20 centers were prospectively recruited. Malignancies investigated included sarcomas (n = 25), brain tumours (n = 23), and others (n = 9). Whole-exome, low-coverage whole-genome, and RNA sequencing were complemented with methylation and expression microarray analyses. Alterations were assessed for potential targetability according to a customised prioritisation algorithm and subsequently discussed in an interdisciplinary molecular tumour board. Next-generation sequencing data were generated for 52 patients, with the full analysis possible in 46 of 52. Turnaround time from sample receipt until first report averaged 28 d. Twenty-six patients (50%) harbored a potentially druggable alteration with a prioritisation score of 'intermediate' or higher (level 4 of 7). Common targets included receptor tyrosine kinases, phosphoinositide 3-kinase-mammalian target of rapamycin pathway, mitogen-activated protein kinase pathway, and cell cycle control. Ten patients received a targeted therapy based on these findings, with responses observed in some previously treatment-refractory tumours. Comparative primary relapse analysis revealed substantial tumour evolution as well as one case of unsuspected secondary malignancy, highlighting the importance of re-biopsy at relapse. This study demonstrates the feasibility of comprehensive, real-time molecular profiling for high-risk paediatric cancer patients. This extended proof-of-concept, with examples of treatment consequences, expands upon previous personalised oncology endeavors

  10. IMMAN: free software for information theory-based chemometric analysis. (United States)

    Urias, Ricardo W Pino; Barigye, Stephen J; Marrero-Ponce, Yovani; García-Jacas, César R; Valdes-Martiní, José R; Perez-Gimenez, Facundo


    The features and theoretical background of a new and free computational program for chemometric analysis denominated IMMAN (acronym for Information theory-based CheMoMetrics ANalysis) are presented. This is multi-platform software developed in the Java programming language, designed with a remarkably user-friendly graphical interface for the computation of a collection of information-theoretic functions adapted for rank-based unsupervised and supervised feature selection tasks. A total of 20 feature selection parameters are presented, with the unsupervised and supervised frameworks represented by 10 approaches in each case. Several information-theoretic parameters traditionally used as molecular descriptors (MDs) are adapted for use as unsupervised rank-based feature selection methods. On the other hand, a generalization scheme for the previously defined differential Shannon's entropy is discussed, as well as the introduction of Jeffreys information measure for supervised feature selection. Moreover, well-known information-theoretic feature selection parameters, such as information gain, gain ratio, and symmetrical uncertainty are incorporated to the IMMAN software ( ), following an equal-interval discretization approach. IMMAN offers data pre-processing functionalities, such as missing values processing, dataset partitioning, and browsing. Moreover, single parameter or ensemble (multi-criteria) ranking options are provided. Consequently, this software is suitable for tasks like dimensionality reduction, feature ranking, as well as comparative diversity analysis of data matrices. Simple examples of applications performed with this program are presented. A comparative study between IMMAN and WEKA feature selection tools using the Arcene dataset was performed, demonstrating similar behavior. In addition, it is revealed that the use of IMMAN unsupervised feature selection methods improves the performance of both IMMAN and WEKA

  11. Cloud-based hospital information system as a service for grassroots healthcare institutions. (United States)

    Yao, Qin; Han, Xiong; Ma, Xi-Kun; Xue, Yi-Feng; Chen, Yi-Jun; Li, Jing-Song


    Grassroots healthcare institutions (GHIs) are the smallest administrative levels of medical institutions, where most patients access health services. The latest report from the National Bureau of Statistics of China showed that 96.04 % of 950,297 medical institutions in China were at the grassroots level in 2012, including county-level hospitals, township central hospitals, community health service centers, and rural clinics. In developing countries, these institutions are facing challenges involving a shortage of funds and talent, inconsistent medical standards, inefficient information sharing, and difficulties in management during the adoption of health information technologies (HIT). Because of the necessity and gravity for GHIs, our aim is to provide hospital information services for GHIs using Cloud computing technologies and service modes. In this medical scenario, the computing resources are pooled by means of a Cloud-based Virtual Desktop Infrastructure (VDI) to serve multiple GHIs, with different hospital information systems dynamically assigned and reassigned according to demand. This paper is concerned with establishing a Cloud-based Hospital Information Service Center to provide hospital information software as a service (HI-SaaS) with the aim of providing GHIs with an attractive and high-performance medical information service. Compared with individually establishing all hospital information systems, this approach is more cost-effective and affordable for GHIs and does not compromise HIT performance.

  12. Information literacy of medical students studying in the problem-based and traditional curriculum

    Directory of Open Access Journals (Sweden)

    Eskola Eeva-Liisa


    Full Text Available This paper reports on part of a research project on the relationships between learning methods and students' information behaviour in Finland. In this qualitative study information behaviour is studied in the contexts of a problem-based learning curriculum and a traditional curriculum. In 1998, 16 theme interviews were conducted at the Tampere University medical school, which applied the problem-based learning curriculum and 15 interviews at the Turku University Medical School, in which the traditional curriculum with an early patient contact programme was implemented. The focus of this paper is on the concept of information literacy as a part of the students' information behaviour. The findings indicate that students' information literacy is developed on the other hand through active use of information and sources in connection with real information needs, on the other hand through an educational context which offers opportunities to get different viewpoints on issues. Superiority of small group instruction compared to lecturing as a teaching method on courses in information searching and the importance of the correct timing of the instruction are confirmed.

  13. Looking beyond the Internet: examining socioeconomic inequalities in cancer information seeking among cancer patients. (United States)

    Lee, Chul-Joo; Ramírez, A Susana; Lewis, Nehama; Gray, Stacy W; Hornik, Robert C


    The gap in cancer information seeking between high-socioeconomic-status (high-SES) cancer patients and low-SES cancer patients deserves serious attention, considering the importance of information and knowledge in cancer control. We thus explored the association of SES, as measured by education, with cancer patients' overall cancer information seeking, and with seeking from each source (i.e., the Internet, mass media, medical sources, and nonmedical interpersonal sources) and across two topic categories (i.e., treatment, quality of life). We then asked whether the effect of education on treatment information seeking is reduced among those who are particularly motivated to control treatment choices. We conducted a survey with breast, prostate, and colon cancer patients diagnosed in 2005 (n = 2,013), who were randomly drawn from the Pennsylvania Cancer Registry in the fall of 2006. We found that education was more strongly associated with Internet use than with the use of other sources regardless of topics. Also, when information was sought from mass media, education had a greater association with treatment information seeking than with quality-of-life information seeking. Preference for active participation in treatment decision making, however, did not moderate the effect of education on treatment information seeking. The implications of these findings for public health research and cancer patient education were discussed.

  14. Reliable and robust transmission and storage techniques for medical images with patient information. (United States)

    Nergui, Myagmarbayar; Acharya, U Sripati; Acharya U, Rajendra; Yu, Wenwei


    There is an increased emphasis on the use of digital techniques in all aspects of human life today. Broadcast radio and television, cellular phone services, consumer and entertainment electronics etc are increasingly using digital signal processing techniques to improve the quality of service. Transmission and storage of documentation and images pertaining to patient records cannot remain an exception to this global trend. Hence, patient records (text and image information) are increasingly stored and processed in digital form. Currently, text and image information, which constitute two separate pieces of data are handled as different files. Thus, there is a possibility of the text and message information, pertaining to different patients, being interchanged and thus mishandled. This can be avoided by merging text and image information in such a manner that the two can be separated without perceptible damage to information contained in either file. Digital watermarking techniques can be used to interleave patient information with medical images. In this work, we have employed digital watermarking along with strong cryptographic protocols and powerful error correcting codes. This reduces the probability of sensitive patient information falling into the wrong hands and ensures information integrity when it is conveyed over noisy channels.

  15. Cooperative coalition for formation flight scheduling based on incomplete information

    Institute of Scientific and Technical Information of China (English)

    Meng Linghang; Xu Xiaohao; Zhao Yifei


    This study analyzes the cooperative coalition problem for formation scheduling based on incomplete information. A multi-agent cooperative coalition framework is developed to optimize the formation scheduling problem in a decentralized manner. The social class differentiation mech-anism and role-assuming mechanism are incorporated into the framework, which, in turn, ensures that the multi-agent system (MAS) evolves in the optimal direction. Moreover, a further differen-tiation pressure can be achieved to help MAS escape from local optima. A Bayesian coalition nego-tiation algorithm is constructed, within which the Harsanyi transformation is introduced to transform the coalition problem based on incomplete information to the Bayesian-equivalent coali-tion problem based on imperfect information. The simulation results suggest that the distribution of agents’ expectations of other agents’ unknown information approximates to the true distribution after a finite set of generations. The comparisons indicate that the MAS cooperative coalition algo-rithm produces a significantly better utility and possesses a more effective capability of escaping from local optima than the proposal-engaged marriage algorithm and the Simulated Annealing algorithm.

  16. Measuring information-based energy and temperature of literary texts (United States)

    Chang, Mei-Chu; Yang, Albert C.-C.; Eugene Stanley, H.; Peng, C.-K.


    We apply a statistical method, information-based energy, to quantify informative symbolic sequences. To apply this method to literary texts, it is assumed that different words with different occurrence frequencies are at different energy levels, and that the energy-occurrence frequency distribution obeys a Boltzmann distribution. The temperature within the Boltzmann distribution can be an indicator for the author's writing capacity as the repertory of thoughts. The relative temperature of a text is obtained by comparing the energy-occurrence frequency distributions of words collected from one text versus from all texts of the same author. Combining the relative temperature with the Shannon entropy as the text complexity, the information-based energy of the text is defined and can be viewed as a quantitative evaluation of an author's writing performance. We demonstrate the method by analyzing two authors, Shakespeare in English and Jin Yong in Chinese, and find that their well-known works are associated with higher information-based energies. This method can be used to measure the creativity level of a writer's work in linguistics, and can also quantify symbolic sequences in different systems.

  18. A Spread Willingness Computing-Based Information Dissemination Model

    Directory of Open Access Journals (Sweden)

    Haojing Huang


    Full Text Available This paper constructs a kind of spread willingness computing based on information dissemination model for social network. The model takes into account the impact of node degree and dissemination mechanism, combined with the complex network theory and dynamics of infectious diseases, and further establishes the dynamical evolution equations. Equations characterize the evolutionary relationship between different types of nodes with time. The spread willingness computing contains three factors which have impact on user’s spread behavior: strength of the relationship between the nodes, views identity, and frequency of contact. Simulation results show that different degrees of nodes show the same trend in the network, and even if the degree of node is very small, there is likelihood of a large area of information dissemination. The weaker the relationship between nodes, the higher probability of views selection and the higher the frequency of contact with information so that information spreads rapidly and leads to a wide range of dissemination. As the dissemination probability and immune probability change, the speed of information dissemination is also changing accordingly. The studies meet social networking features and can help to master the behavior of users and understand and analyze characteristics of information dissemination in social network.

  19. Neighborhood Hypergraph Based Classification Algorithm for Incomplete Information System

    Directory of Open Access Journals (Sweden)

    Feng Hu


    Full Text Available The problem of classification in incomplete information system is a hot issue in intelligent information processing. Hypergraph is a new intelligent method for machine learning. However, it is hard to process the incomplete information system by the traditional hypergraph, which is due to two reasons: (1 the hyperedges are generated randomly in traditional hypergraph model; (2 the existing methods are unsuitable to deal with incomplete information system, for the sake of missing values in incomplete information system. In this paper, we propose a novel classification algorithm for incomplete information system based on hypergraph model and rough set theory. Firstly, we initialize the hypergraph. Second, we classify the training set by neighborhood hypergraph. Third, under the guidance of rough set, we replace the poor hyperedges. After that, we can obtain a good classifier. The proposed approach is tested on 15 data sets from UCI machine learning repository. Furthermore, it is compared with some existing methods, such as C4.5, SVM, NavieBayes, and KNN. The experimental results show that the proposed algorithm has better performance via Precision, Recall, AUC, and F-measure.

  20. Constructing osteoarthritis through discourse – a qualitative analysis of six patient information leaflets on osteoarthritis

    Directory of Open Access Journals (Sweden)

    Ong Bie


    Full Text Available Abstract Background Health service policy in the United Kingdom emphasises the importance of self-care by patients with chronic conditions. Written information for patients about their condition is seen as an important aid to help patients look after themselves. From a discourse analysis perspective written texts such as patient information leaflets do not simply describe the reality of a medical condition and its management but by drawing on some sorts of knowledge and evidence rather than others help construct the reality of that condition. This study explored patient information leaflets on osteoarthritis (OA to see how OA was constructed and to consider the implications for self-care. Methods Systematic and repeated readings of six patient information leaflets on osteoarthritis to look for similarities and differences across leaflets, contradictions within leaflets and the resources called on to make claims about the nature of OA and its management. Results Biomedical discourse of OA as a joint disease dominated. Only one leaflet included an illness discourse albeit limited, and was also the only one to feature patient experiences of living with OA. The leaflets had different views on the causes of OA including the role of lifestyle and ageing. Most emphasised patient responsibility for preventing the progression of OA. Advice about changing behaviour such as diet and exercise was not grounded in lived experience. There were inconsistent messages about using painkillers, exercise and the need to involve professionals when making changes to lifestyle. Conclusion The nature of the discourse impacted on how OA and the respective roles of patients and professionals were depicted. Limited discourse on illness meant that the complexity of living with OA and its consequences was underestimated. Written information needs to shift from joint biology to helping patients live with osteoarthritis. Written information should incorporate patient

    Full Text Available This paper studies the information content of survey-based predictions for the Brazilian short-term interest rate. We perform vector autoregression analysis to test for the dynamic relationship between market expectations of interest rates and spot interest rates, and a single regression forecasting approach. Empirical results suggest that surveys may be useful in assessing market expectations (contain relevant information and in building Central Bank credibility. Within an inflation targeting framework they are crucial in order to receive timely feedback on market sentiment regarding the conduct of monetary policy.

    This paper proposes a novel method for color restoration that can effectively apply accurate color based on spectral information to a segmented image using the normalized cut technique. Using the proposed method, we can obtain a digital still camera image and spectral information in different environments. Also, it is not necessary to estimate reflectance spectra using a spectral database such as other methods. The synthesized images are accurate and high resolution. The proposed method effectively works in making digital archive contents. Some experimental results are demonstrated in this paper.

    Yongqing Qi; Zhongliang Jing; Shiqiang Hu


    The bias estimation of passive sensors is considered based on information fusion in multi-platform multisensor tracking system. The unobservable problem of bearing-only tracking in blind spot is analyzed. A modified maximum likelihood method, which uses the redundant information of multi-sensor system to calculate the target position, is investigated to estimate the biases. Monte Carlo simulation results show that the modified method eliminates the effect of unobservable problem in the blind spot and can estimate the biases more rapidly and accurately than maximum likelihood method. It is statistically efficient since the standard deviation of bias estimation errors meets the theoretical lower bounds.

  7. Information-Based Physics and the Influence Network

    CERN Document Server

    Knuth, Kevin H


    This essay considers a simple model of observers that are influenced by the world around them. Consistent quantification of information about such influences results in a great deal of familiar physics. The end result is a new perspective on relativistic quantum mechanics, which includes both a way of conceiving of spacetime as well as particle "properties" that may be amenable to a unification of quantum mechanics and gravity. Rather than thinking about the universe as a computer, perhaps it is more accurate to think about it as a network of influences where the laws of physics derive from both consistent descriptions and optimal information-based inferences made by embedded observers.

  8. Electrophysiological correlates of information processing in breast-cancer patients treated with adjuvant chemotherapy. (United States)

    Kreukels, Baudewijntje P C; Schagen, Sanne B; Ridderinkhof, K Richard; Boogerd, Willem; Hamburger, Hans L; van Dam, Frits S A M


    Cognitive deficits are found in a number of breast-cancer patients who have undergone adjuvant (Cyclophosphamide, Methotrexate, and 5-Fluorouracil (CMF)) chemotherapy, but the underlying mechanisms are still unclear. The objective of this study is to investigate information processing in these patients with concurrent registration of brain activity. Twenty-six breast-cancer patients treated with adjuvant CMF chemotherapy and a control group of 23 stage I breast-cancer patients not treated with chemotherapy were examined. Mean time since treatment for the CMF patients was 5.1 years after the last CMF course, and for the control patients 3.6 years after termination of radiotherapy. An information processing task was administered with concurrent EEG registration. Reaction times and the amplitudes and latencies of an Event Related Potential component (P3) in different task conditions related to input, central, and output processing of information were studied. Significant differences in latency and amplitude of the P3 component were found between the treatment groups with an earlier and reduced P3 in the chemotherapy group. Patients treated with chemotherapy had longer reaction times (although not significantly different) than the control group on all task conditions. Our data provide further evidence for long-term neurocognitive problems in breast-cancer patients treated with adjuvant (CMF) chemotherapy and offer new information regarding abnormalities in brain functioning in these patients.

    Silcock Jonathan


    Full Text Available Abstract Background Studies suggest that the process of patient consent to clinical trials is sub-optimal. Participant information sheets are important but can be technical and lengthy documents. Performance-based readability testing is an established means of assessing patient information, and this study aimed to test its application to participant information for a Phase 3 trial. Methods An independent groups design was used to study the User Testing performance of the participant information sheet from the Phase 3 'Poor Responders' trial of In Vitro Fertilisation (IVF. 20 members of the public were asked to read it, then find and demonstrate understanding of 21 key aspects of the trial. The participant information sheet was then re-written and re-designed, and tested on 20 members of the public, using the same 21 item questionnaire. Results The original participant information sheet performed well in some places. Participants could not find some answers and some of the found information was not understood. In total there were 30 instances of information being not found or not understood. Answers to three questions were found but not understood by many of the participants, these related to aspects of the drug timing, Follicle Stimulating Hormone and compensation. Only two of the 20 participants could find and show understanding of all question items when using the original sheet. The revised sheet performed generally better, with 17 instances of information being not found or not understood, although the number of 'not found' items increased. Half of the 20 participants could find and show understanding of all question items when using the revised sheet. When asked to compare the versions of the sheet, almost all participants preferred the revised version. Conclusion The original participant information sheet may not have enabled patients fully to give valid consent. Participants seeing the revised sheet were better able to understand the

  10. Empirical studies on informal patient payments for health care services: a systematic and critical review of research methods and instruments

    Directory of Open Access Journals (Sweden)

    Pavlova Milena


    Full Text Available Abstract Background Empirical evidence demonstrates that informal patient payments are an important feature of many health care systems. However, the study of these payments is a challenging task because of their potentially illegal and sensitive nature. The aim of this paper is to provide a systematic review and analysis of key methodological difficulties in measuring informal patient payments. Methods The systematic review was based on the following eligibility criteria: English language publications that reported on empirical studies measuring informal patient payments. There were no limitations with regard to the year of publication. The content of the publications was analysed qualitatively and the results were organised in the form of tables. Data sources were Econlit, Econpapers, Medline, PubMed, ScienceDirect, SocINDEX. Results Informal payments for health care services are most often investigated in studies involving patients or the general public, but providers and officials are also sample units in some studies. The majority of the studies apply a single mode of data collection that involves either face-to-face interviews or group discussions. One of the main methodological difficulties reported in the publication concerns the inability of some respondents to distinguish between official and unofficial payments. Another complication is associated with the refusal of some respondents to answer questions on informal patient payments. We do not exclude the possibility that we have missed studies that reported in non-English language journals as well as very recent studies that are not yet published. Conclusions Given the recent evidence from research on survey methods, a self-administrated questionnaire during a face-to-face interview could be a suitable mode of collecting sensitive data, such as data on informal patient payments.

  11. The Frequentist Information Criterion (FIC): The unification of information-based and frequentist inference

    CERN Document Server

    LaMont, Colin H


    The failure of the information-based Akaike Information Criterion (AIC) in the context of singular models can be rectified by the definition of a Frequentist Information Criterion (FIC). FIC applies a frequentist approximation to the computation of the model complexity, which can be estimated analytically in many contexts. Like AIC, FIC can be understood as an unbiased estimator of the model predictive performance and is therefore identical to AIC for regular models in the large-observation-number limit ($N\\rightarrow \\infty$) . In the presence of unidentifiable parameters, the complexity exhibits a more general, non-AIC-like scaling ($\\gg N^0$). For instance, both BIC-like ($\\propto\\log N$) and Hannan-Quinn-like ($\\propto \\log \\log N$) scaling with observation number $N$ are observed. Unlike the Bayesian model selection approach, FIC is free from {\\it ad hoc} prior probability distributions and appears to be widely applicable to model selection problems. Finally we demonstrate that FIC (information-based inf...

    This paper describes a developed continuous patient monitoring system based on the ZigBee protocol. The system was tested in the hospital environment using six sensor devices in two different modes. For electrocardiogram transmission and in the absence of hidden-nodes, the system achieved a mean delivery ratio of 100% and 98.56%, respectively for star and 2-hop tree network topologies. When sensor devices were arranged in a way that three of them were unable to hear the transmissions made by the other three, the mean delivery ratio dropped to 83.96%. However, when sensor devices were reprogrammed to transmit only heart rate values, the mean delivery ratio increased to 99.90%, despite the presence of hidden-nodes.

  14. An improved biometrics-based authentication scheme for telecare medical information systems. (United States)

    Guo, Dianli; Wen, Qiaoyan; Li, Wenmin; Zhang, Hua; Jin, Zhengping


    Telecare medical information system (TMIS) offers healthcare delivery services and patients can acquire their desired medical services conveniently through public networks. The protection of patients' privacy and data confidentiality are significant. Very recently, Mishra et al. proposed a biometrics-based authentication scheme for telecare medical information system. Their scheme can protect user privacy and is believed to resist a range of network attacks. In this paper, we analyze Mishra et al.'s scheme and identify that their scheme is insecure to against known session key attack and impersonation attack. Thereby, we present a modified biometrics-based authentication scheme for TMIS to eliminate the aforementioned faults. Besides, we demonstrate the completeness of the proposed scheme through BAN-logic. Compared to the related schemes, our protocol can provide stronger security and it is more practical.

  15. Design and implementation of a smart card based healthcare information system. (United States)

    Kardas, Geylani; Tunali, E Turhan


    Smart cards are used in information technologies as portable integrated devices with data storage and data processing capabilities. As in other fields, smart card use in health systems became popular due to their increased capacity and performance. Their efficient use with easy and fast data access facilities leads to implementation particularly widespread in security systems. In this paper, a smart card based healthcare information system is developed. The system uses smart card for personal identification and transfer of health data and provides data communication via a distributed protocol which is particularly developed for this study. Two smart card software modules are implemented that run on patient and healthcare professional smart cards, respectively. In addition to personal information, general health information about the patient is also loaded to patient smart card. Health care providers use their own smart cards to be authenticated on the system and to access data on patient cards. Encryption keys and digital signature keys stored on smart cards of the system are used for secure and authenticated data communication between clients and database servers over distributed object protocol. System is developed on Java platform by using object oriented architecture and design patterns.

Data was used by coordinating nurses for time activation of TT and MET involved in the initial treatment of severely-injured or critically-ill patients....... DISCUSSION: The contradiction of measured median wait time and nurses perceived improved timing of team activation may result from having both RT- ETA and supplemental patient information not only for seriously-injured or critically-ill patients received by the TT and MET, but for all patients transported...

  17. Critical care nurses' information-seeking behaviour during an unfamiliar patient care task. (United States)

    Newman, Kristine M; Doran, Diane


    Critical care nurses complete tasks during patient care to promote the recovery or maintain the health of their patients. These tasks can be routine or non-routine to the nurse. Non-routine tasks are characterized by unfamiliarity, requiring nurses to seek additional information from a variety of sources to effectively complete the tasks. Critical care units are dynamic environments where decisions are often made by nurses under stress and time pressure because patient status changes rapidly. A non-routine task (e.g., administration of an unfamiliar medication) to the critical care nurse can impact patient care outcomes (e.g., increased time to complete task has consequences for the patient). In this article, the authors discuss literature reviewed on nurses' information-seeking and explore an information-seeking conceptual model that will be used as a guide to examine the main concepts found through the empirical evidence.

  18. RSS based CERN Alerter. Information broadcast to all CERN offices.

    CERN Multimedia

    Otto, R


    Nearly every large organization uses a tool to broadcast messages and information across the internal campus (messages like alerts announcing interruption in services or just information about upcoming events). These tools typically allow administrators (operators) to send "targeted" messages which are sent only to specific groups of users or computers, e/g only those located in a specified building or connected to a particular computing service. CERN has a long history of such tools: CERNVMS€™s SPM_quotMESSAGE command, Zephyr and the most recent the NICE Alerter based on the NNTP protocol. The NICE Alerter used on all Windows-based computers had to be phased out as a consequence of phasing out NNTP at CERN. The new solution to broadcast information messages on the CERN campus continues to provide the service based on cross-platform technologies, hence minimizing custom developments and relying on commercial software as much as possible. The new system, called CERN Alerter, is based on RSS (Really Simpl...

  19. Measuring trends in performance across time: providing information to cancer patients. (United States)

    Fitch, Margaret I; McAndrew, Alison; Harth, Tamara


    Providing relevant, up-to-date information is identified as a quality standard of cancer care. Cancer programs need to be able to evaluate whether they are meeting the standard and to monitor their performance on an ongoing basis. Routine collection of clearly defined data, using reliable and valid measures, provides cancer program leaders with dependable information upon which to make decisions and monitor trends in performance over time. This article describes one cancer centre's experience in using standardized data collection regarding provision of patient information. The Cancer Patient Information Importance-Satisfaction Scale has been administered routinely in an outpatient setting over eight years. The profile we create from the data assists us in making informed decisions about patient education initiatives.

  2. Prediction of tectonically deformed coal based on lithologic seismic information (United States)

    Li, Juanjuan; Pan, Dongming; Cui, Ruofei; Ding, Enjie; Zhang, Wei; Hu, Mingshun


    Owing to the differences in physical properties between tectonically deformed coal (TDC) and primary coal, lithologic seismic inversion methods were adopted to identify the coal structure type, including probabilistic neural network (PNN) inversion, elastic impedance (EI) inversion and simultaneous inversion methods. Based on poststack and prestack gathers, the inversion methods were applied to calculate lithologic seismic information, which included porosity, acoustic impedance, elastic impedance, λ × ρ and μ × ρ data. The inversion results were then analysed to evaluate the development potential of TDC. The research showed that the lithology inversion results, which indicated the potential zone of development areas of the coal, were all basically identical and a comprehensive prediction factor (the linear lithologic information combination) was proposed to effectively predict the development potential. Therefore, the prediction of TDC by lithologic seismic information could provide a scientific basis for both coal mining safety and the development potential of large-scale coalbed methane resources.

  3. Information system based on the mathematical model of the EPS (United States)

    Kalimoldayev, Maksat N.; Abdildayeva, Assel A.; Mamyrbayev, Orken Zh.; Akhmetzhanov, Maksat


    This article discusses the structure of an information system, the mathematical and information models of electric power systems. Currently, the major application areas include system relaying data communication systems and automation, automated dispatching and technological management of electric power facilities, as well as computer-aided calculation of energy resources. Automatic control of excitation (ARV) synchronous machines is one of the most effective ways to ensure the stability of power systems. However, the variety of possible options and modes even in a single grid pose significant obstacles to the development of the best means of ensuring sustainability. Thus, the use of ARVs to ensure stability in some cases may not be sufficient. Therefore, there is a need to develop an information system based on a mathematical model.

  4. Multiagent Based Information Dissemination in Vehicular Ad Hoc Networks

    Directory of Open Access Journals (Sweden)

    S.S. Manvi


    Full Text Available Vehicular Ad hoc Networks (VANETs are a compelling application of ad hoc networks, because of the potential to access specific context information (e.g. traffic conditions, service updates, route planning and deliver multimedia services (Voice over IP, in-car entertainment, instant messaging, etc.. This paper proposes an agent based information dissemination model for VANETs. A two-tier agent architecture is employed comprising of the following: 1 'lightweight', network-facing, mobile agents; 2 'heavyweight', application-facing, norm-aware agents. The limitations of VANETs lead us to consider a hybrid wireless network architecture that includes Wireless LAN/Cellular and ad hoc networking for analyzing the proposed model. The proposed model provides flexibility, adaptability and maintainability for traffic information dissemination in VANETs as well as supports robust and agile network management. The proposed model has been simulated in various network scenarios to evaluate the effectiveness of the approach.

    Full Text Available Due to student overreliance on search engines and the time constraints of one-shot instruction sessions, librarians struggle to teach many of the information literacy skills that students need to conduct successful research. Problem-based learning (PBL provides a way to integrate information literacy naturally into an assignment or course by guiding students through the research process as they work to find a solution to a problem. This article first explains the PBL process, then describes the design and implementation of a PBL project in a required first-year general education course. Finally, it details the Association of College & Research Libraries’ (ACRL Information Literacy Competency Standards for Higher Education addressed by the project, as well as possible future modifications.

  6. A Method of Image Symmetry Detection Based on Phase Information

    Institute of Scientific and Technical Information of China (English)

    WU Jun; YANG Zhaoxuan; FENG Dengchao


    Traditional methods for detecting symmetry in image suffer greatly from the contrast of image and noise, and they all require some preprocessing. This paper presents a new method of image symmetry detection. This method detects symmetry with phase information utilizing logGabor wavelets, because phase information is stable and significant, while symmetric points produce patterns easy to be recognised and confirmable in local phase. Phase method does not require any preprocessing, and its result is accurate or invariant to contrast, rotation and illumination conditions. This method can detect mirror symmetry, rotating symmetry and curve symmetry at one time. Results of experiment show that, compared with pivotal element algorithm based on intensity information, phase method is more accurate and robust.

  8. Information management in software engineering: A hypertext based approach

    Energy Technology Data Exchange (ETDEWEB)

    Garg, P.K.


    Large scale software systems requires automated support for the communication and coordination of cooperative effort required to manage, create, store, print, and use large volumes of information. Hypertext is a flexible, general purpose, non-linear model for storing textual information. The thesis of this dissertation is that software engineering information should be managed using a hypertext based approach. Previous models of software engineering information do not provide the flexibility and generality of a hypertext model. We describe the design and implementation of an Intelligent Software Hypertext System (Ishys), for management of software engineering information. In Ishys, Basic Templates (BTs) are nodes of a hypertext, which can have point-to-point and node-to-node links. Forms are sequences of BTs which can be used to model software life cycle documents. Compositions are arbitrary collections of BTs. Projects represent partitions of the hypertext such that each project has the same forms. Tasks are responsibilities of agents which use or produce forms. Tasks are composed of actions which use or produce BTs. Actions are composed of primitive actions which are commands provided through Ishys. In a general user mode, users create information in Ishys by instantiating BTs. In a super user mode, users define the projects, forms, BTs, tasks, actions, and primitive actions. Structured communication about BTs is supported through annotations attached to different points within BTs. To illustrate the flexibility and generality of the hypertext based approach we show how a hypertext can support generalizations, specializations, revisions, and aggregations. To illustrate the power of hypertext systems in supporting collaborative work, we discuss how a hypertext system can support two models for composition of node composition: (1) the assembly line model, and (2) the exploratory assembly model.

  9. Carpal tunnel syndrome: Analysis of online patient information with the EQIP tool. (United States)

    Frueh, F S; Palma, A F; Raptis, D A; Graf, C P; Giovanoli, P; Calcagni, M


    Patients suffering from carpal tunnel syndrome (CTS) actively search for medical information on the Internet. The World Wide Web represents the main source of patient information. The aim of this study was to systematically assess the quality of patient information about CTS in the Internet. A qualitative and quantitative assessment of websites was performed with the modified Ensuring Quality Information for Patients (EQIP) tool that contains 36 standardized items. Five hundred websites with information on CTS treatment options were identified through Google, Bing, Yahoo, and AOL. Duplicates and irrelevant websites were excluded. One hundred and ten websites were included. Only five websites addressed more than 20 items; quality scores were not significantly different between the various providing groups. A median of 15 EQIP items was found, with the top website addressing 26 out of 36 items. Major complications such as median nerve injury were reported in 27% of the websites and their treatment in only 3%. This analysis revealed several critical shortcomings in the quality of the information provided to patients suffering from CTS. There is a collective need to provide interactive, informative and educational websites for standard procedures in hand surgery. These websites should be compatible with international quality standards for hand surgery procedures.

  10. Health information technologies in systemic lupus erythematosus: focus on patient assessment. (United States)

    Tani, Chiara; Trieste, Leopoldo; Lorenzoni, Valentina; Cannizzo, Sara; Turchetti, Giuseppe; Mosca, Marta


    Recent advances in health information technologies (HIT) in systemic lupus erythematosus have included electronic databases and registries, computerised clinical charts for patient monitoring, computerised diagnostic tools, computerised prediction rules and, more recently, disease-specific applications for mobile devices for physicians, health care professionals, and patients. Traditionally, HIT development has been oriented primarily to physicians and public administrators. However, more recent development of patient-centered Apps could improve communication and empower patients in the daily management of their disease. Economic advantages could also result from the use of HIT, including these Apps by collecting real life data that could be used in both economic analyses and to improve patient care.

    Directory of Open Access Journals (Sweden)

    Matthew E Falagas

    Full Text Available BACKGROUND: We sought to perform a study to record and evaluate patients' views of the way surgeons communicate informed consent (IC in Greece. METHODOLOGY/PRINCIPAL FINDINGS: A prospective pilot study was carried out in Athens from 9/2007 to 4/2008. The study sample was extracted from patients, operated by eight different surgeons, who volunteered to fill in a post-surgery self-report questionnaire on IC. A composite delivered information index and a patient-physician relationship index were constructed for the purposes of the analysis. In total, 77 patients (42 males volunteered to respond to the questionnaire. The delivered information index scores ranged from 3 to 10, the mean score was 8, and the standard deviation (SD was 1.9. All patients were aware of their underlying diagnosis and reason for surgery. However, a considerable proportion of the respondents (14.3% achieved a score below or equal to 5. The patient-physician relationship scores ranged from 0 to 20, the mean score was 16 and the standard deviation (SD was 4.3. The better the patient-physician relationship, the more information was finally delivered to the patient from the physician (Spearman's rank-order correlation coefficient was 0.4 and p<0.001. Delivered information index was significantly higher among participants who comprehended the right to informed consent, compared to participants who did not (p<0.001, and among participants who were given information regarding other possible therapeutic options (p = 0.001. 43% of the respondents answered that less than 10 minutes were spent on the consent process, 58.4% of patients stated that they had not been informed about other possible therapeutic choices and 28.6% did not really comprehend their legal rights to IC. CONCLUSIONS: Despite the inherent limitations and the small sample size that do not permit to draw any firm conclusions, results indicate that a successful IC process may be associated with specific elements such as

  13. A chaotic map-based authentication scheme for telecare medicine information systems. (United States)

    Hao, Xinhong; Wang, Jiantao; Yang, Qinghai; Yan, Xiaopeng; Li, Ping


    With the development of Internet, patients could enjoy health-care delivery services through telecare medicine information systems (TMIS) in their home. To control the access to remote medical servers' resources, many authentication schemes using smart cards have been proposed. However, the performance of these schemes is not satisfactory since modular exponential operations are used in these schemes. In the paper, we propose a chaotic map-based authentication scheme for telecare medicine information systems. The security and performance analysis shows our scheme is more suitable for TMIS.

  14. Local Stereo Matching Based on Information Entropy of Image (United States)

    Geng, Yingnan


    Adaptive support-window algorithm is one of the simplest local algorithms for stereo matching. An important problem for adaptive support-window algorithm is to determine the appropriate support-window size, which is always hard to do and limits the validity of adaptive support-window algorithm. An appropriate support-window size must be selected adaptively based on image features. In this paper, information entropy of image is defined for stereo matching in the RGB vector space. Based on adaptive support-window, a new support-window selection algorithm, which uses information entropy of image to quantify image features such as illumination color and number of object contained in an image, is proposed. Experimental results evaluated on the Middlebury stereo benchmark show that our algorithm outperforms the conventional adaptive support-window algorithms.

  15. Networks in financial markets based on the mutual information rate. (United States)

    Fiedor, Paweł


    In the last few years there have been many efforts in econophysics studying how network theory can facilitate understanding of complex financial markets. These efforts consist mainly of the study of correlation-based hierarchical networks. This is somewhat surprising as the underlying assumptions of research looking at financial markets are that they are complex systems and thus behave in a nonlinear manner, which is confirmed by numerous studies, making the use of correlations which are inherently dealing with linear dependencies only baffling. In this paper we introduce a way to incorporate nonlinear dynamics and dependencies into hierarchical networks to study financial markets using mutual information and its dynamical extension: the mutual information rate. We show that this approach leads to different results than the correlation-based approach used in most studies, on the basis of 91 companies listed on the New York Stock Exchange 100 between 2003 and 2013, using minimal spanning trees and planar maximally filtered graphs.

  16. Human Age Estimation Based on Locality and Ordinal Information. (United States)

    Li, Changsheng; Liu, Qingshan; Dong, Weishan; Zhu, Xiaobin; Liu, Jing; Lu, Hanqing


    In this paper, we propose a novel feature selection-based method for facial age estimation. The face aging is a typical temporal process, and facial images should have certain ordinal patterns in the aging feature space. From the geometrical perspective, a facial image can be usually seen as sampled from a low-dimensional manifold embedded in the original high-dimensional feature space. Thus, we first measure the energy of each feature in preserving the underlying local structure information and the ordinal information of the facial images, respectively, and then we intend to learn a low-dimensional aging representation that can maximally preserve both kinds of information. To further improve the performance, we try to eliminate the redundant local information and ordinal information as much as possible by minimizing nonlinear correlation and rank correlation among features. Finally, we formulate all these issues into a unified optimization problem, which is similar to linear discriminant analysis in format. Since it is expensive to collect the labeled facial aging images in practice, we extend the proposed supervised method to a semi-supervised learning mode including the semi-supervised feature selection method and the semi-supervised age prediction algorithm. Extensive experiments are conducted on the FACES dataset, the Images of Groups dataset, and the FG-NET aging dataset to show the power of the proposed algorithms, compared to the state-of-the-arts.

  17. Agents Based e-Commerce and Securing Exchanged Information (United States)

    Al-Jaljouli, Raja; Abawajy, Jemal

    Mobile agents have been implemented in e-Commerce to search and filter information of interest from electronic markets. When the information is very sensitive and critical, it is important to develop a novel security protocol that can efficiently protect the information from malicious tampering as well as unauthorized disclosure or at least detect any malicious act of intruders. In this chapter, we describe robust security techniques that ensure a sound security of information gathered throughout agent’s itinerary against various security attacks, as well as truncation attacks. A sound security protocol is described, which implements the various security techniques that would jointly prevent or at least detect any malicious act of intruders. We reason about the soundness of the protocol usingSymbolic Trace Analyzer (STA), a formal verification tool that is based on symbolic techniques. We analyze the protocol in key configurations and show that it is free of flaws. We also show that the protocol fulfils the various security requirements of exchanged information in MAS, including data-integrity, data-confidentiality, data-authenticity, origin confidentiality and data non-repudiability.

  18. A cloud-based information repository for bridge monitoring applications (United States)

    Jeong, Seongwoon; Zhang, Yilan; Hou, Rui; Lynch, Jerome P.; Sohn, Hoon; Law, Kincho H.


    This paper describes an information repository to support bridge monitoring applications on a cloud computing platform. Bridge monitoring, with instrumentation of sensors in particular, collects significant amount of data. In addition to sensor data, a wide variety of information such as bridge geometry, analysis model and sensor description need to be stored. Data management plays an important role to facilitate data utilization and data sharing. While bridge information modeling (BrIM) technologies and standards have been proposed and they provide a means to enable integration and facilitate interoperability, current BrIM standards support mostly the information about bridge geometry. In this study, we extend the BrIM schema to include analysis models and sensor information. Specifically, using the OpenBrIM standards as the base, we draw on CSI Bridge, a commercial software widely used for bridge analysis and design, and SensorML, a standard schema for sensor definition, to define the data entities necessary for bridge monitoring applications. NoSQL database systems are employed for data repository. Cloud service infrastructure is deployed to enhance scalability, flexibility and accessibility of the data management system. The data model and systems are tested using the bridge model and the sensor data collected at the Telegraph Road Bridge, Monroe, Michigan.

  19. Dutch hospitals provide reliable "one click" patient information using a Quality Window. (United States)

    Van Rooy, Yvonne


    In 2014, the Dutch Association of Hospitals (Nederlandse Vereniging van Ziekenhuizen, NVZ) launched the "Quality Window" at general hospitals across the Netherlands. The Quality Window is an online platform for patients which shares a hospital's current and previous scores on ten quality indicators, from patient experience to employee satisfaction. The Quality Window therefore responds to the growing demand for information and transparency when it comes to hospital care and performance. Not only can patients access helpful information about a hospital's quality through the Quality Window, they can also compare results with other hospitals, the national average, and more. Many hospitals also take the opportunity to expand on how indicators work in practice and the actions being taken towards improvement. The Quality Window was developed with the help of hospitals and patients. Over the coming years it will be expanded to university hospitals across the country. General hospitals will also begin developing Quality Windows for specific patient groups, such as cancer patients.

    Lui, Leong Ting; Terrazas, Germán; Zenil, Hector; Alexander, Cameron; Krasnogor, Natalio


    In the past decades many definitions of complexity have been proposed. Most of these definitions are based either on Shannon's information theory or on Kolmogorov complexity; these two are often compared, but very few studies integrate the two ideas. In this article we introduce a new measure of complexity that builds on both of these theories. As a demonstration of the concept, the technique is applied to elementary cellular automata and simulations of the self-organization of porphyrin molecules.

  8. The information-seeking behaviour of paediatricians accessing web-based resources.

    LENUS (Irish Health Repository)

    Prendiville, T W


    OBJECTIVES: To establish the information-seeking behaviours of paediatricians in answering every-day clinical queries. DESIGN: A questionnaire was distributed to every hospital-based paediatrician (paediatric registrar and consultant) working in Ireland. RESULTS: The study received 156 completed questionnaires, a 66.1% response. 67% of paediatricians utilised the internet as their first "port of call" when looking to answer a medical question. 85% believe that web-based resources have improved medical practice, with 88% reporting web-based resources are essential for medical practice today. 93.5% of paediatricians believe attempting to answer clinical questions as they arise is an important component in practising evidence-based medicine. 54% of all paediatricians have recommended websites to parents or patients. 75.5% of paediatricians report finding it difficult to keep up-to-date with new information relevant to their practice. CONCLUSIONS: Web-based paediatric resources are of increasing significance in day-to-day clinical practice. Many paediatricians now believe that the quality of patient care depends on it. Information technology resources play a key role in helping physicians to deliver, in a time-efficient manner, solutions to clinical queries at the point of care.

    Little, A


    Hospital survival requires adaptation, adaptation requires understanding, and understanding requires information. These are the basic equations behind hospital strategic marketing, and one of the answers may lie in hospitals' own patient-data systems. Marketers' and administrators' enlightened application of case-mix information could become one more hospital survival tool.

    Full Text Available Aims Hospital information system may offer a way to increased self-care management. The aim of this study was to determine the patients’ informational needs for self-care management and evaluation of different HIS software according to these needs. Materials & Methods This descriptive cross-sectional study was done during 2011-2012 in Kashan City, Iran at two phases; compiling the required information, and evaluation. The questionnaire items were discussed in three conversation sessions with 20 faculty members by Delphi technique. 15 HIS software provider companies in Iran were selected purposefully and 2 hospitals from each company were participated in the study. Data were analyzed by SPSS 16 software using Chi-square test. Findings 7 items in the health protection dimension were covered by HIS software; “Need to consult with attending physicians”, “Length of disease duration”, “Diagnostic and treatment cost resource”, “Different treatment approach”, “Convenient information recourses”, “Offer good information resources”, and “Prognosis”. No item of health promotion dimension were supported by any HIS software. 6 items in the health maintenance dimension were covered completely by all HIS software; “Blood Sugar”, “hct”, “hb”, “Blood Group Type”, “CBC/Diff”, and “Electrolytes”. Conclusion Present HIS software can not meet the self-care management informational needs of recently discharged patients and should be improved.

  18. Content-based Image Retrieval by Information Theoretic Measure

    Directory of Open Access Journals (Sweden)

    Madasu Hanmandlu


    Full Text Available Content-based image retrieval focuses on intuitive and efficient methods for retrieving images from databases based on the content of the images. A new entropy function that serves as a measure of information content in an image termed as 'an information theoretic measure' is devised in this paper. Among the various query paradigms, 'query by example' (QBE is adopted to set a query image for retrieval from a large image database. In this paper, colour and texture features are extracted using the new entropy function and the dominant colour is considered as a visual feature for a particular set of images. Thus colour and texture features constitute the two-dimensional feature vector for indexing the images. The low dimensionality of the feature vector speeds up the atomic query. Indices in a large database system help retrieve the images relevant to the query image without looking at every image in the database. The entropy values of colour and texture and the dominant colour are considered for measuring the similarity. The utility of the proposed image retrieval system based on the information theoretic measures is demonstrated on a benchmark dataset.Defence Science Journal, 2011, 61(5, pp.415-430, DOI:

  19. Online information as a decision making aid for cancer patients: recommendations from the Eurocancercoms project. (United States)

    Maddock, Carol; Camporesi, Silvia; Lewis, Ian; Ahmad, Kafait; Sullivan, Richard


    A pan-European survey was conducted under the auspices of the FP7 Eurocancercoms project during the period September 2010-March 2011. It was designed to broaden public policy understanding of patients' specific needs when seeking online cancer information and aimed to identify gaps in the online cancer information provision across Europe. In this paper we describe the methodology and main findings of the Tenovus survey, and draw some recommendations on the use of online information as a decision making aid for cancer patients and their families, namely: (1) transparency and accountability of the sources of information presented online; (2) accreditation of information by different recognised forms of authority and expertise, i.e. both by health-care professional and by patients/public members belonging to patient advocacy groups; (3) scaling up of information: we envisage a 3-tiered system that would enable patients to access different levels of complexity and volume of information from summary to detailed; (4) embedding of custom search tools and interactive search technologies to allow users to define requirements tailored on their needs and be context-driven; (5) communication across discipline boundaries, as patients' and doctors' online communities have very little or no contact among one another. These recommendations were applied for building the online platform EcancerHub, also under the auspices of the Eurocancercoms project, which by bringing together the different cancer communities seeks to break down traditional information boundaries, and through the interactions produce a surplus knowledge that could aid patients in difficult decision making times.

  1. Informing the patient about a fatal disease: from paternalism to autonomy--the Jewish view. (United States)

    Rosner, Fred


    Until the late 20th century, withholding a fatal diagnosis functioned as a paradigm for sharing other medical information with patients. The obligation of confidentiality was emphasized and disclosure was ignored. Ethicists perceived the doctor-patient relationship as oriented to therapy, reassurance, and avoiding harm. Physicians were to provide lies and truth instrumentally only insofar as they aided therapy (Jameton, A. Information disclosure. Ethical issues. In Encyclopedia of Bioethics. Revised Ed.; Reich, T.N.T., Ed.; MacMillan: New York, 1995; Vol. 3, 1225-1232). This was the era of paternalism. Since the 1960s, opinion on the role of disclosure was changed rapidly in the United States stimulated by the patient's rights movement and the rise of bioethics. The current climate supports honest and complete disclosure of medical information. In 1972, the Board of Trustees of the American Hospital Association affirmed A Patient's Bill of Rights, which states that the patient has the right to obtain from his physician complete current information concerning his diagnosis, treatment, and prognosis in terms the patient can be reasonably expected to understand (Lee, A.L.; Jacobs, G. Workshop airs patient's rights. Hospitals 1973, 47, 39-43). Bioethicists now favor full disclosure as a means of respecting patient autonomy (Katz, J. The Silent World of Doctor and Patient; Free Press: New York, 1984). The American College of Physician Ethics Manual states that disclosure to patients is a fundamental ethical requirement (American College of Physicians. American College of Physicians Ethics Manual, 3rd Ed. Ann. Intern. Med. 1992, 117, 947-960). The era of patient autonomy ended the traditional pattern of withholding information, which was characteristic of the previous era of paternalism. The Jewish view toward full disclosure of a fatal illness to a patient and especially a patient who is terminally ill is in general a negative one because of the fear that the patient

    Oldfield Eddie


    Full Text Available Abstract Background There is great concern within health surveillance, on how to grapple with environmental degradation, rapid urbanization, population mobility and growth. The Internet has emerged as an efficient way to share health information, enabling users to access and understand data at their fingertips. Increasingly complex problems in the health field require increasingly sophisticated computer software, distributed computing power, and standardized data sharing. To address this need, Web-based mapping is now emerging as an important tool to enable health practitioners, policy makers, and the public to understand spatial health risks, population health trends and vulnerabilities. Today several web-based health applications generate dynamic maps; however, for people to fully interpret the maps they need data source description and the method used in the data analysis or statistical modeling. For the representation of health information through Web-mapping applications, there still lacks a standard format to accommodate all fixed (such as location and variable (such as age, gender, health outcome, etc indicators in the representation of health information. Furthermore, net-centric computing has not been adequately applied to support flexible health data processing and mapping online. Results The authors of this study designed a HEalth Representation XML (HERXML schema that consists of the semantic (e.g., health activity description, the data sources description, the statistical methodology used for analysis, geometric, and cartographical representations of health data. A case study has been carried on the development of web application and services within the Canadian Geospatial Data Infrastructure (CGDI framework for community health programs of the New Brunswick Lung Association. This study facilitated the online processing, mapping and sharing of health information, with the use of HERXML and Open Geospatial Consortium (OGC services

    O.M. Posnenkova


    Full Text Available A new follow-up technology of dynamic out-patient control based on system of mobile monitoring of patients with arterial hypertension (SMMAH has been created in Saratov Scientific Research Institute of Cardiology. SMMAH is based on exchange of information between patient and doctor with the help of Internet and standard short mobile messages. The aim of the present work is to study the effectiveness of SMMAH for follow-up control of hypertensive patients for the period of 12 months. 79 patients with hypertension aged 49±11 were included in the investigation. Control period lasted 12 months. Control visits were made in the 1st, 6th and 12th months. The number of patients became out of control, its causes, percentage of patients who achieved and maintained target blood pressure (BP were analyzed after each visit. Data were presented as M (95% confidence interval. As a result in 1 month period of investigation 88,6% of patients regularly used mobile messages, 11% of patients were out of control. In 6 months period 68,4% of participants were under control, 31,6% of patients dropped out. In 12 months period — 67% and 33% of patients accordingly. Target BP was maintained in 87% (77%-96% of patients in 1 month period, in 78% (66%-90% of patients in 6 months period and in 68% of patients (53%-84% in 12 months period. High clinical effectiveness of SMMAH has been proved during the study: 67% of patients have followed prescribed therapy after the investigation period and 68% of them have maintained target BP level.

  4. Information retrieval and terminology extraction in online resources for patients with diabetes. (United States)

    Seljan, Sanja; Baretić, Maja; Kucis, Vlasta


    Terminology use, as a mean for information retrieval or document indexing, plays an important role in health literacy. Specific types of users, i.e. patients with diabetes need access to various online resources (on foreign and/or native language) searching for information on self-education of basic diabetic knowledge, on self-care activities regarding importance of dietetic food, medications, physical exercises and on self-management of insulin pumps. Automatic extraction of corpus-based terminology from online texts, manuals or professional papers, can help in building terminology lists or list of "browsing phrases" useful in information retrieval or in document indexing. Specific terminology lists represent an intermediate step between free text search and controlled vocabulary, between user's demands and existing online resources in native and foreign language. The research aiming to detect the role of terminology in online resources, is conducted on English and Croatian manuals and Croatian online texts, and divided into three interrelated parts: i) comparison of professional and popular terminology use ii) evaluation of automatic statistically-based terminology extraction on English and Croatian texts iii) comparison and evaluation of extracted terminology performed on English manual using statistical and hybrid approaches. Extracted terminology candidates are evaluated by comparison with three types of reference lists: list created by professional medical person, list of highly professional vocabulary contained in MeSH and list created by non-medical persons, made as intersection of 15 lists. Results report on use of popular and professional terminology in online diabetes resources, on evaluation of automatically extracted terminology candidates in English and Croatian texts and on comparison of statistical and hybrid extraction methods in English text. Evaluation of automatic and semi-automatic terminology extraction methods is performed by recall

    Full Text Available Objective – The author aims to study the aggregate influence of demographic and situational variables on the information needs of cancer patients, in order to inform the provision of information to those patients. Design – Meta-analysis. Setting – Research articles published in the MEDLINE and CINAHL databases. Subjects – English language studies published between 1993 and 2003. An initial search set of 196 studies from MEDLINE and 283 studies from CINAHL were identified. Following rigorous assessment, 12 studies met the inclusion criteria. Methods – A comprehensive search of the databases was conducted, initially combining “neoplasm” with “cancer patients” using the Boolean “or”. These results were then combined with five separate searches using the following terms; information need(s, information seeking, information seeking behaviour, information source(s and information resource(s. This identified in total 479 English language articles. Based on a review of titles and abstracts, 110 articles were found covering information resources or the information needs of cancer patients. These articles were then subjected to the further inclusion criteria and limited to studies which included: analysis of information needs and/or information sources of cancer patients; adults as subjects of the research; and application of quantitative research methods and relevant statistics. This eliminated a further 35 papers. Twelve of the remaining 75 studies were selected for meta‐analysis based on their use of the same variables measured consistently in comparable units. The final 12 studies included various forms of cancer, and no distinction was made among them. All 12 studies appeared in peer‐reviewed journals. Main results – The meta‐analysis found there was consistently no difference between the information needs of men and women. Five subsets were identified within the meta‐analysis, and findings for each can be stated as

  6. Problem decomposition by mutual information and force-based clustering (United States)

    Otero, Richard Edward

    The scale of engineering problems has sharply increased over the last twenty years. Larger coupled systems, increasing complexity, and limited resources create a need for methods that automatically decompose problems into manageable sub-problems by discovering and leveraging problem structure. The ability to learn the coupling (inter-dependence) structure and reorganize the original problem could lead to large reductions in the time to analyze complex problems. Such decomposition methods could also provide engineering insight on the fundamental physics driving problem solution. This work forwards the current state of the art in engineering decomposition through the application of techniques originally developed within computer science and information theory. The work describes the current state of automatic problem decomposition in engineering and utilizes several promising ideas to advance the state of the practice. Mutual information is a novel metric for data dependence and works on both continuous and discrete data. Mutual information can measure both the linear and non-linear dependence between variables without the limitations of linear dependence measured through covariance. Mutual information is also able to handle data that does not have derivative information, unlike other metrics that require it. The value of mutual information to engineering design work is demonstrated on a planetary entry problem. This study utilizes a novel tool developed in this work for planetary entry system synthesis. A graphical method, force-based clustering, is used to discover related sub-graph structure as a function of problem structure and links ranked by their mutual information. This method does not require the stochastic use of neural networks and could be used with any link ranking method currently utilized in the field. Application of this method is demonstrated on a large, coupled low-thrust trajectory problem. Mutual information also serves as the basis for an

  10. Cancer stage knowledge and desire for information: mismatch in Latino cancer patients? (United States)

    Costas-Muniz, Rosario; Sen, Rohini; Leng, Jennifer; Aragones, Abraham; Ramirez, Julia; Gany, Francesca


    Having more health knowledge has a crucial and positive impact on cancer outcomes. Patients' cancer knowledge influences their ability to participate actively in decision-making processes for medical care and in treatment choices. The purpose of this study was to determine the demographic and medical correlates of lack of cancer stage knowledge and desire for information among Latino cancer patients. The sample included 271 underserved Latino cancer patients recruited from four cancer clinics in New York City. Participants completed a needs assessment survey in their preferred language, which included sociodemographic and health-related questions. Close to two-thirds of the sample (65%) had no knowledge of their stage, and 38% were unaware of the metastatic state of their tumor. Only 15% of the patients expressed that they would like additional information about their diagnosis and/or treatment. After controlling for sociodemographic characteristics, being an immigrant with limited English proficiency and monolingual in Spanish were predictors of stage unawareness and less desire/need for cancer information. Patients needing interpretation for health care were less likely to know whether their tumor had metastasized and their cancer stage and to desire information about their cancer diagnosis and/or treatment. This study shows considerably low levels of stage awareness among Latinos diagnosed with cancer. This lack of knowledge might adversely impact their treatment decisions and disease management. Future studies should focus on identifying barriers to acquisition of disease information and other disease-specific informational deficits.

  11. Information quality measurement of medical encoding support based on usability. (United States)

    Puentes, John; Montagner, Julien; Lecornu, Laurent; Cauvin, Jean-Michel


    Medical encoding support systems for diagnoses and medical procedures are an emerging technology that begins to play a key role in billing, reimbursement, and health policies decisions. A significant problem to exploit these systems is how to measure the appropriateness of any automatically generated list of codes, in terms of fitness for use, i.e. their quality. Until now, only information retrieval performance measurements have been applied to estimate the accuracy of codes lists as quality indicator. Such measurements do not give the value of codes lists for practical medical encoding, and cannot be used to globally compare the quality of multiple codes lists. This paper defines and validates a new encoding information quality measure that addresses the problem of measuring medical codes lists quality. It is based on a usability study of how expert coders and physicians apply computer-assisted medical encoding. The proposed measure, named ADN, evaluates codes Accuracy, Dispersion and Noise, and is adapted to the variable length and content of generated codes lists, coping with limitations of previous measures. According to the ADN measure, the information quality of a codes list is fully represented by a single point, within a suitably constrained feature space. Using one scheme, our approach is reliable to measure and compare the information quality of hundreds of codes lists, showing their practical value for medical encoding. Its pertinence is demonstrated by simulation and application to real data corresponding to 502 inpatient stays in four clinic departments. Results are compared to the consensus of three expert coders who also coded this anonymized database of discharge summaries, and to five information retrieval measures. Information quality assessment applying the ADN measure showed the degree of encoding-support system variability from one clinic department to another, providing a global evaluation of quality measurement trends.

  12. The librarian's role in linking patients to their personal health data and contextual information. (United States)

    Tarver, Talicia; Jones, Dixie A; Adams, Mararia; Garcia, Alejandro


    The objective of this project was to make an institution's patients aware of a new patient portal with contextual links to MedlinePlus. Through partnerships with information technology personnel and LSU Health Shreveport clinics, the Health Sciences Library created and distributed promotional and educational materials and instructed patients on how to use MyChart and access reliable consumer health information via MedlinePlus Connect. Although most patients were not interested in coming to the library for demonstrations, many of them expressed interest in using MyChart. The contextual information in MedlinePlus Connect worked well for most topics. The institutional team leader for MyChart expressed gratitude for librarian involvement.

  13. Patients' preferences for video cassette recorded information: effect of age, sex and ethnic group. (United States)

    Thomas, R; Deary, A; Kaminski, E; Stockton, D; De Zueew, N


    The emotional turmoil patients endure following a diagnosis of cancer can impair their ability to retain complex treatment-related information. Manoeuvres which increase the intensity of information have been shown to increase the amount retained. Providing details of treatment in a video format is one method of intensifying information provision, but the attitudes of patients to this format have not previously been evaluated. In this pilot study, the attitudes of 300 patients to video directed information were evaluated via questionnaires, of which 210 (70%) were returned. Eighty-nine per cent had easy access to a video cassette player. A highly significant number felt that the video would be very helpful or helpful (78%) compared to not helpful, worrying or equivocal 21% (P < 0.0001). This trend was particularly strong in patients < 60 years (83% versus 17%) (P < 0.0001) and those from ethnic groups (95% versus 5%) (P < 0.0001). As a result of this trial, a 20-min film (HEP) has been commissioned. It describes details of the two main treatments for cancer after surgery, namely chemotherapy and radiotherapy, shows patients actually having treatment, and explains the common side-effects and ways to alleviate them. Patients satisfaction with the film and its effect on anxiety and depression are currently being evaluated in an international prospective randomized trial. If it proves advantageous for patients--in view of the ethnic group bias in this study--it will be translated into the ethnic languages of the UK.

    Full Text Available The risk of adverse pregnancy outcomes can be minimized through the adoption of healthy lifestyles before pregnancy by women of childbearing age. Initiatives for promotion of preconception health may be difficult to implement. Internet can be used to build tailored health interventions through identification of the public's information needs. To this aim, we developed a semi-automatic web-based system for monitoring Google searches, web pages and activity on social networks, regarding preconception health.Based on the American College of Obstetricians and Gynecologists guidelines and on the actual search behaviors of Italian Internet users, we defined a set of keywords targeting preconception care topics. Using these keywords, we analyzed the usage of Google search engine and identified web pages containing preconception care recommendations. We also monitored how the selected web pages were shared on social networks. We analyzed discrepancies between searched and published information and the sharing pattern of the topics.We identified 1,807 Google search queries which generated a total of 1,995,030 searches during the study period. Less than 10% of the reviewed pages contained preconception care information and in 42.8% information was consistent with ACOG guidelines. Facebook was the most used social network for sharing. Nutrition, Chronic Diseases and Infectious Diseases were the most published and searched topics. Regarding Genetic Risk and Folic Acid, a high search volume was not associated to a high web page production, while Medication pages were more frequently published than searched. Vaccinations elicited high sharing although web page production was low; this effect was quite variable in time.Our study represent a resource to prioritize communication on specific topics on the web, to address misconceptions, and to tailor interventions to specific populations.

    Full Text Available Rebecca Harris, Claire Noble, Victoria Lowers Institute of Psychology, Health and Society, University of Liverpool, Liverpool, UK Abstract: Neoliberal emphasis on “responsibility” has colonized many aspects of public life, including how health care is provided. Clinical risk assessment of patients based on a range of data concerned with lifestyle, behavior, and health status has assumed a growing importance in many health systems. It is a mechanism whereby responsibility for self (preventive care can be shifted to patients, provided that risk assessment data is communicated to patients in a way which is engaging and motivates change. This study aimed to look at whether the form in which tailored risk information was presented in a clinical setting (for example, using photographs, online data, diagrams etc., was associated with differences in patients’ responses and preferences to the material presented. We undertook a systematic review using electronic searching of nine databases, along with handsearching specialist journals and backward and forward citation searching. We identified eleven studies (eight with a randomized controlled trial design. Seven studies involved the use of computerized health risk assessments in primary care. Beneficial effects were relatively modest, even in studies merely aiming to enhance patient–clinician communication or to modify patients’ risk perceptions. In our paper, we discuss the apparent importance of the accompanying discourse between patient and clinician, which appears to be necessary in order to impart meaning to information on “risk,” irrespective of whether the material is personalized, or even presented in a vivid way. Thus, while expanding computer technologies might be able to generate a highly personalized account of patients’ risk in a time efficient way, the need for face-to-face interactions to impart meaning to the data means that these new technologies cannot fully address the

  16. Healthy Aging Promotion through Neuroscientific Information-Based Strategies. (United States)

    Seinfeld, Sofia; Sanchez-Vives, Maria V


    To ensure the well-being of a rapidly growing elderly population, it is fundamental to find strategies to foster healthy brain aging. With this intention, we designed a program of scientific-based lectures aimed at dissemination by established neuroscientists about brain function, brain plasticity and how lifestyle influences the brain. We also carried out a pilot study on the impact of the lectures on attendees. The objective was to provide information to elderly people in order to encourage them to identify unhealthy and healthy daily habits, and more importantly, to promote behavioral changes towards healthy brain aging. Here we report on our experience. In order to determine the impact of the lectures in the daily routine of the attendees, we asked them to fill out questionnaires. Preliminary results indicate that neuroscientific information-based strategies can be a useful method to have a positive impact on the lives of elderly, increase their awareness on how to improve brain function and promote positive lifestyle modifications. Furthermore, based on self-reported data, we also found that through this strategy it is possible to promote behavioral changes related to nutrition, sleep, and realization of physical and cognitively stimulating activities. Finally, based on the results obtained, the importance of promoting self-efficacy and the empowerment of the older populations is highlighted.

  17. Do patient preferences for health information vary by health literacy or numeracy? A qualitative assessment. (United States)

    Gaglio, Bridget; Glasgow, Russell E; Bull, Sheana S


    Seeking health information can be a complicated process for a patient. Patients must know the topic of interest, where to look or ask, how to assess and comprehend, and how to evaluate the credibility and trustworthiness of the sources. In this study, the authors describe preferences of patients with multiple risk factors for cardiovascular disease with varying health literacy and numeracy abilities for receiving health information. Participants were recruited from 2 health care systems. Health literacy and numeracy were assessed and participants completed an orally administered survey consisting of open-ended questions about obtaining health information and preferences for health information. In-depth interviews were conducted with a subset of participants. A diverse sample of 150 individuals (11.3% Latino, 37.3% African American, 44.7% with income less than $15,000/year) participated. Most participants had adequate functional health literacy, while 65% had low numeracy skills. Regardless of health literacy or numeracy ability, participants overwhelmingly preferred to receive health information during a face-to-face conversation with their health care provider. While individuals with adequate functional health literacy identified a variety of health information sources, actions are needed to ensure multiple modalities are available and are in plain, clear language that reinforces patients' understanding and application of information to health behavior.

  18. Physician-patient communication from the perspective of library and information science. (United States)

    Baker, L M; Connor, J J


    The physician-patient communication process has received little attention from library and information science (LIS) professionals. A limited review of other literature on this topic was undertaken to gain some understanding of the information exchange from an LIS perspective. The authors were interested in four issues, including how information is defined; how information-seeking behavior is portrayed; what barriers to information exist in the exchange process; and what role, if any, information plays in health outcomes. Studies have been conducted by researchers in various disciplines who have defined communication as a giving and seeking activity between the physician and the patient. Barriers to good communication, erected by either party or by both, prevent the participants from experiencing a satisfactory encounter. Because information can play a role in health outcomes, various strategies have been tried to improve the communication process. These studies provide a better understanding of the physician-patient encounter and suggest new areas of patient-centered research for LIS professionals.

  19. Predictors of Burden Among Informal Caregivers of Patients with Chemotherapy-Induced Anemia in the United States, France and Italy



    PROBLEM: Informal caregivers of patients with chemotherapy-induced anemia (CIA) experience unaddressed burden. Previous research typically quantified burden with a score based on an instrument scale, but did not examine drivers or relative importance of clinical, demographic, and other characteristics on burden. As caregiver outcomes may be mediated by burden (a modifiable factor), research on predictors of burden are needed to identify points to target in designing interventions and policies...

    Full Text Available Today’s World Wide Web has large volume of data – billions of documents. So it is a time consuming process to discover effective knowledge from the input data. With today's keyword approach the amount of time and effort required to find the right information is directly proportional to the amount of information on the web.The web has grown exponentially and people are forced to spend more and more time in search for the information they are looking for. Lack of personalization as well as inability to easily separate commercial from non-commercial searches is among other limitations of today's web search technologies. This paper proposes a prototype relation-based search engine. “OntoLook” which has been designed in a virtual semantic web environment. The architecture has been proposed. The Semantic Web is well recognized as an effective infrastructure to enhance visibility of knowledge on the Web. The core of the Semantic Web is “ontology”, which is used to explicitly represent our conceptualizations. Ontology engineering in the Semantic Web isprimarily supported by languages such as RDF, RDFS and OWL. This paper discusses the requirements of ontology in the context of the Web, compares the above three languages with existing knowledge representation formalisms, and surveys tools for managing and applying ontology. Advantages of using ontology in both knowledge-base-style and database-style applications are demonstrated using one real world applications.
