  2. Development of Patient Status-Based Dynamic Access System for Medical Information Systems

    Chang Won Jeong


    Full Text Available Recently, the hospital information system environment using IT communication technology and utilization of medical information has been increasing. In the medical field, the medical information system only supports the transfer of patient information to medical staff through an electronic health record, without information about patient status. Hence, it needs a method of real-time monitoring for the patient. Also, in this environment, a secure method in approaching healthcare through various smart devices is required. Therefore, in this paper, in order to classify the status of the patients, we propose a dynamic approach of the medical information system in a hospital information environment using the dynamic access control method. Also, we applied the symmetric method of AES (Advanced Encryption Standard. This was the best encryption algorithm for sending and receiving biological information. We can define usefulness as the dynamic access application service based on the final result of the proposed system. The proposed system is expected to provide a new solution for a convenient medical information system.

  3. [Trial of information sharing for home-based patient care using Cybozu Live , a cloud-based groupware].

    Asahina, Kan


    Home-based patient care involves several different care services of specialties, so that it is crucial to share patient information effectively among the caregivers. To overcome the problems with conventional means for storing and sharing information, we introduced Cybozu Live , a cloud-based groupware provided for free of charge. As a result, the amount of information shared increased while telephone and facsimile transactions dramatically decreased. A questionnaire survey revealed that the caregivers generally appreciated the use of this groupware; they felt that more information was needed for tasks while the load of using telephone and facsimile is minimal. We found the followings through our experiences: 1 ) Simply sharing information can largely contribute to supporting patients and their families; 2 ) Awareness of patients, families and caregivers is more important in the homecare information sharing than are numerical data; 3 ) Effective information sharing creates a sense of togetherness of the team beyond mere co-operation among the staff; 4 ) Effective information sharing provides learning opportunities for caregivers; and 5 ) An appropriate tool such as Cybozu Live is needed for effective information sharing.

  4. Wavelet-Based ECG Steganography for Protecting Patient Confidential Information in Point-of-Care Systems.

    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.

  5. Implementing health information technology in a patient-centered manner: patient experiences with an online evidence-based lifestyle intervention.

    Lyden, Jennifer R; Zickmund, Susan L; Bhargava, Tina D; Bryce, Cindy L; Conroy, Molly B; Fischer, Gary S; Hess, Rachel; Simkin-Silverman, Laurey R; McTigue, Kathleen M


    The patient-centered care (PCC) model and the use of health information technology (HIT) are major initiatives for improving U.S. healthcare quality and delivery. A lack of published data on patient perceptions of Internet-based care makes patient-centered implementation of HIT challenging. To help ascertain patients' perceptions of an online intervention, patients completing a 1-year web-based lifestyle intervention were asked to complete a semistructured interview. We used qualitative methodology to determine frequency and types of interview responses. Overall satisfaction with program features was coded on a Likert-type scale. High levels of satisfaction were seen with the online lifestyle coaching (80%), self-monitoring tools (57%), and structured lesson features (54%). Moderated chat sessions and online resources were rarely used. Frequently identified helpful aspects were those that allowed for customized care and shared decision-making consistent with the tenets of PCC. Unhelpful program aspects were reported less often. Findings suggest that despite challenges for communicating effectively in an online forum, the personalized support, high-tech data management capabilities, and easily followed evidence-based curricula afforded by HIT may be a means of providing PCC and improving healthcare delivery and quality.

    Jae Ok, L; Won-Ki, M; Mi Na, K; Won-Sub, K; Kyoung Soo, L; Tae-Hwan, L; Han Ik, C


    Introduction It is essential to have a proper health care delivery system for the efficient management of clinical resources for a nation. In Korea, we have observed numerous problems of missing or delaying clinical information when referring patients to a nearby secondary or tertiary care hospital. Patient referral is usually done at random but no reliable information is provided for appropriate care. Furthermore, no follow-up information is sent back to referring institutions when the care ...

  7. Characterization of mammographic masses based on level set segmentation with new image features and patient information

    Computer-aided diagnosis (CAD) for characterization of mammographic masses as malignant or benign has the potential to assist radiologists in reducing the biopsy rate without increasing false negatives. The purpose of this study was to develop an automated method for mammographic mass segmentation and explore new image based features in combination with patient information in order to improve the performance of mass characterization. The authors' previous CAD system, which used the active contour segmentation, and morphological, textural, and spiculation features, has achieved promising results in mass characterization. The new CAD system is based on the level set method and includes two new types of image features related to the presence of microcalcifications with the mass and abruptness of the mass margin, and patient age. A linear discriminant analysis (LDA) classifier with stepwise feature selection was used to merge the extracted features into a classification score. The classification accuracy was evaluated using the area under the receiver operating characteristic curve. The authors' primary data set consisted of 427 biopsy-proven masses (200 malignant and 227 benign) in 909 regions of interest (ROIs) (451 malignant and 458 benign) from multiple mammographic views. Leave-one-case-out resampling was used for training and testing. The new CAD system based on the level set segmentation and the new mammographic feature space achieved a view-based Az value of 0.83±0.01. The improvement compared to the previous CAD system was statistically significant (p=0.02). When patient age was included in the new CAD system, view-based and case-based Az values were 0.85±0.01 and 0.87±0.02, respectively. The study also demonstrated the consistency of the newly developed CAD system by evaluating the statistics of the weights of the LDA classifiers in leave-one-case-out classification. Finally, an independent test on the publicly available digital database for screening

  9. The experiential health information processing model: supporting collaborative web-based patient education

    Wathen C Nadine


    Full Text Available Abstract Background First generation Internet technologies such as mailing lists or newsgroups afforded unprecedented levels of information exchange within a variety of interest groups, including those who seek health information. With emergence of the World Wide Web many communication applications were ported to web browsers. One of the driving factors in this phenomenon has been the exchange of experiential or anecdotal knowledge that patients share online, and there is emerging evidence that participation in these forums may be having an impact on people's health decision making. Theoretical frameworks supporting this form of information seeking and learning have yet to be proposed. Results In this article, we propose an adaptation of Kolb's experiential learning theory to begin to formulate an experiential health information processing model that may contribute to our understanding of online health information seeking behaviour in this context. Conclusion An experiential health information processing model is proposed that can be used as a research framework. Future research directions include investigating the utility of this model in the online health information seeking context, studying the impact of collaborating in these online environments on patient decision making and on health outcomes are provided.

  11. Discrete wavelet transform and singular value decomposition based ECG steganography for secured patient information transmission.

    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. PMID:25187409

  13. Computerized tracking of mammography patients: value of a radiology information system integrated with a personal-computer data base.

    Frank, M S; Johnson, J A


    OBJECTIVE. We investigated the advantages of using a radiology information system as the primary data source for a mammographic patient-tracking system that is based on a personal-computer local-area network and that requires almost no data entry. HARDWARE AND SOFTWARE. Our mammographic data base is maintained on a file server that provides cross-platform access to both Macintosh and IBM-compatible personal computers. Locally developed software automatically transfers mammographic data from our radiology information system to the file server's mammographic data base. The data transferred include patients' demographics (e.g., hospital identification number, address, referring physician) and the complete mammographic report. With the use of specific terminology, the need for follow-up can be automatically gleaned from the mammographic report and coded within the data base. Graphically oriented, commercially available software provides easy access to this information from any personal computer on our department's network. The software provides considerable flexibility for searching and manipulating the data without the need for customized data-base programming. Redundant data entry and associated errors are drastically reduced, as are personnel requirements for maintaining the system. Relative to most commercial radiology information systems, a personal computer facilitates the steps involved in tracking patients and obtaining highly customized analyses of the mammographic data base. The data in the mammographic data base exactly match those in the hospital's registration data and are easily transferred to other personal-computer programs for ancillary processing. CONCLUSION. This technique is ideal for departments that use a general-purpose radiology information system for mammographic reporting, yet need a more powerful but user-friendly and low-cost method for tracking their mammography patients.

  15. Blood glucose testing and primary prevention of diabetes mellitus type 2 - evaluation of the effect of evidence based patient information

    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.

    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. A DICOM-RT Based ePR radiation therapy information system for decision-support of brain tumor patients

    Liu, B. J.; Law, M.; Huang, H. K.; Zee, C. S.; Chan, L.


    The need for comprehensive clinical image data and relevant information in image-guided Radiation Therapy (RT) is becoming steadily apparent. Multiple standalone systems utilizing the most technological advancements in imaging, therapeutic radiation, and computerized treatment planning systems acquire key data during the RT treatment course of a patient. One example are patients treated for brain tumors of greater sizes and irregular shapes that utilize state-of-the-art RT technology to deliver pinpoint accurate radiation doses. Various treatment options are available to the patient from Radiation Therapy to Stereotactic Radiosurgery and utilize different RT modalities. The disparate and complex data generated by the RT modalities along with related data scattered throughout the RT department in RT Information/Management systems, Record & Verify systems, and Treatment Planning Systems (TPS) compromise an efficient clinical workflow since the data crucial for a clinical decision may be time-consuming to retrieve, temporarily missing, or even lost. To address these shortcomings, the ACR-NEMA Standards Committee extended its DICOM (Digital Imaging & Communications in Medicine) Standard from Radiology to RT by ratifying seven DICOM RT objects starting in 1997. However, they are rarely used by the RT community in daily clinical operations. In the past, the research focus of an RT department has primarily been developing new protocols and devices to improve treatment process and outcomes of cancer patients with minimal effort dedicated to integration of imaging and information systems. By combining our past experience in medical imaging informatics research, DICOM-RT expertise, and system integration, our research involves using a brain tumor case model to show proof-of-concept that a DICOM-Standard electronic patient record (ePR) system can be developed as a foundation to perform medical imaging informatics research in developing decision-support tools and knowledge

  20. A DICOM-RT based ePR radiation therapy information system for managing brain tumor patients

    Liu, Brent J.; Law, Maria; Huang, H. K.; Zee, C. S.; Chan, Lawrence


    The need for comprehensive clinical image data and relevant information in image-guided Radiation Therapy (RT) is becoming steadily apparent. Multiple standalone systems utilizing the most technological advancements in imaging, therapeutic radiation, and computerized treatment planning systems acquire key data during the RT treatment course of a patient. One example are patients treated for brain tumors of greater sizes and irregular shapes that utilize state-of-the-art RT technology to deliver pinpoint accurate radiation doses. One such system, the Cyberknife, is a radiation treatment system that utilizes image-guided information to control a multi-jointed, six degrees of freedom, robotic arm to deliver precise and required radiation dose to the tumor site of a cancer patient. The image-guided system is capable of tracking the lesion orientations with respect to the patient"s position throughout the treatment process. This is done by correlating live radiographic images with pre-operative, CT and MR imaging information to determine relative patient and tumor position repeatedly over the course of the treatment. The disparate and complex data generated by the Cyberknife system along with related data is scattered throughout the RT department compromising an efficient clinical workflow since the data crucial for a clinical decision may be time-consuming to retrieve, temporarily missing, or even lost. To address these shortcomings, the ACR-NEMA Standards Committee extended its DICOM (Digital Imaging & Communications in Medicine) Standard from Radiology to RT by ratifying seven DICOM RT objects starting in 1997.

  1. [Information programs for patients during gastroenterological rehabilitation].

    Ikas, G


    Patient education especially groups for patients with inflammatory bowel disease belong to the typical tasks of Reha-medicine. In the Reha-Clinic "Ob der Tauber", Bad Mergentheim these patients are informed in special Colitis/Crohn-groups for eleven years now. Normally approximately ten patients with IBD are treated in our house at the same time. These patients participate in a nearly closed group in which they are taught in three weeks blocks. Three hours a week the patients are informed by doctors, one hour a week a diet assistant teaches the participants. The psychotherapeutic group takes place regularly once a week. The aim of the patient information or health education is to reach a mostly complete information of the patients about inflammatory bowel disease, that means to inform them about all diagnostic and therapeutic possibilities. Another important purpose of team work is the support of dynamic group processes like reduction of anxiety and the influence on the patients for developing an active positive attitude towards their disease. The participating therapist (doctors, psychotherapist, diet-assistant) have created a structured concept which was modified during the last years. Resulting from the interactive work between therapist and patients this concept is improved continuously. This development however is delayed by the shortcomming of bad personal capacities and the lack of possibilities for the therapist to improve their pedagogic and psychotherapeutic abilities. At the moment their education is based on autodidactic methods and empathy. For a standardization of the program including all hospitals the extended curriculum of the GRVS is useful. An evaluation concerning the therapeutic benefit of patient information has not been done yet. PMID:11930302

  4. Evidence-based neurosurgery. Basic concepts for the appraisal and application of scientific information to patient care (Part II).

    Esene, Ignatius N; Baeesa, Saleh S; Ammar, Ahmed


    Medical evidence is obtainable from approaches, which might be descriptive, analytic and integrative and ranked into levels of evidence, graded according to quality and summarized into strengths of recommendation. Sources of evidence range from expert opinions through well-randomized control trials to meta-analyses. The conscientious, explicit, and judicious use of current best evidence in making decisions related to the care of individual patients defines the concept of evidence-based neurosurgery (EBN). We reviewed reference books of clinical epidemiology, evidence-based practice and other previously related articles addressing principles of evidence-based practice in neurosurgery. Based on existing theories and models and our cumulative years of experience and expertise conducting research and promoting EBN, we have synthesized and presented a holistic overview of the concept of EBN. We have also underscored the importance of clinical research and its relationship to EBN. Useful electronic resources are provided. The concept of critical appraisal is introduced. PMID:27356649

  6. High-quality Health Information Provision for Stroke Patients

    Du, Hong-Sheng; Ma, Jing-Jian; Li, Mu


    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. PMID:27569241

  7. Tailored Patient Information Some Issues and Questions

    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.

  8. The patient's opinion of informed consent

    To evaluate the quality of the information provided by informed consent forms for angiography and interventional radiology on the basis of the patients opinion. A descriptive study was performed based on an anonymous survey distributed among patients who were to undergo angiography and interventional radiology, and had previously been informed and provided with the corresponding informed consent form. A descriptive and analytical statistical study was carried out to compare the responses to the questions concerning different factors (Mann-Whitney U test). Of the 182 surveys completed 75.3% corresponded to diagnostic procedures and the remaining 24.7% to therapeutic procedures. When the responses to closed-ended questions were analyzed, 90.1% of respondents considered the amount of information provided by the document to be sufficient 75.3% declared that they found the form easy to comprehend and 34.1% responded that reading it had calmed their nerves. Statistically significant differences were observed, depending on whether the form corresponded to diagnostic or therapeutic procedures, concerning the questions related to comprehension of the document and to the feeling upon reading it, with those used for diagnostic procedures obtaining better scores. There was a statistically significant difference between the responses of the patients to the question concerning their feeling upon reading the document and the responses of family members, with the patients responding more favorably than their relatives. The consent forms prepared for angiography and interventional radiology procedures are acceptable to the patients concerned with respect to both the quantity and the quality of the information.

  9. Informing evidence-based decision-making for patients with comorbidity: availability of necessary information in clinical trials for chronic diseases.

    Cynthia M Boyd

    Full Text Available BACKGROUND: The population with multiple chronic conditions is growing. Prior studies indicate that patients with comorbidities are frequently excluded from trials but do not address whether information is available in trials to draw conclusions about treatment effects for these patients. METHODS AND FINDINGS: We conducted a literature survey of trials from 11 Cochrane Reviews for four chronic diseases (diabetes, heart failure, chronic obstructive pulmonary disease, and stroke. The Cochrane Reviews systematically identified and summarized trials on the effectiveness of diuretics, metformin, anticoagulants, longacting beta-agonists alone or in combination with inhaled corticosteroids, lipid lowering agents, exercise and diet. Eligible studies were reports of trials included in the Cochrane reviews and additional papers that described the methods of these trials. We assessed the exclusion and inclusion of people with comorbidities, the reporting of comorbidities, and whether comorbidities were considered as potential modifiers of treatment effects. Overall, the replicability of both the inclusion criteria (mean [standard deviation (SD]: 6.0 (2.1, range (min-max: 1-9.5 and exclusion criteria (mean(SD: 5.3 (2.1, range: 1-9.5 was only moderate. Trials excluded patients with many common comorbidities. The proportion of exclusions for comorbidities ranged from 0-42 percent for heart failure, 0-55 percent for COPD, 0-44 percent for diabetes, and 0-39 percent for stroke. Seventy of the 161 trials (43.5% described the prevalence of any comorbidity among participants with the index disease. The reporting of comorbidities in trials was very limited, in terms of reporting an operational definition and method of ascertainment for the presence of comorbidity and treatments for the comorbidity. It was even less common that the trials assessed whether comorbidities were potential modifiers of treatment effects. CONCLUSIONS: Comorbidities receive little attention

    Clinicians rely heavily on expert based systems-consultation with colleagues, journal reviews and textbooks, and continuing education activities-to obtain new information. The usefulness of sources such as these depends on the relevance and validity of the information and the work it takes to obtain it. Useful information can be distinguished from the useless by asking three questions: Does the information focus on an outcome that my patients care about? Is the issue common to my practice, an...

  12. Pharmacogenetic information for patients on drug labels

    Haga SB


    Full Text Available Susanne B Haga, Rachel Mills, Jivan Moaddeb Center for Applied Genomics and Precision Medicine, Department of Medicine, Duke University, Durham, NC, USA Abstract: 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.

  13. An Evaluation of the Rates of Repeat Notifiable Disease Reporting and Patient Crossover Using a Health Information Exchange-based Automated Electronic Laboratory Reporting System

    Gichoya, Judy; Gamache, Roland E.; Vreeman, Daniel J.; Dixon, Brian E.; Finnell, John T.; Grannis, Shaun


    Patients move across healthcare organizations and utilize services with great frequency and variety. This fact impacts both health information technology policy and patient care. To understand the challenges faced when developing strategies for effective health information exchange, it is important to understand patterns of patient movement and utilization for many healthcare contexts, including managing public-health notifiable conditions. We studied over 10 years of public-health notifiable...

  14. 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.

  15. Patient information in radiooncology. Results of a patient survey

    Background: As a result of increased interest and public demand, providing patients with adequate information about radiooncology has become more and more difficult for the doctor. Insufficient patient information can not only cause anxiety for the patient, but can also lead to legal action against the physician. In order to gain a deeper insight into our clinical practice of providing patient information, we developed a special questionnaire. We describe our first experiences in using this questionnaire at our institute. Patients and methods: We examine the amount of information and level of satisfaction, as well as the agreement of assessment between patient and physician after the provision of standard patient information before and at the end of radiotherapy. 51 consecutive patients were interviewed with a newly designed questionnaire. The first questioning with 13 items was carried out before radiotherapy and the second with ten items was done at the end of treatment. Sum scores for information and satisfaction were defined and agreement was measured by the weighted κ coefficient. Results: Global level of information and satisfaction was good, and a significant increase in information level and a significant decline in satisfaction were seen between questionnaire 1 and 2. Agreement between patient and physician was fair, for example intent of treatment resulted in a κ coefficient of 0.34, and poor for the doctor's role with a κ coefficient of -0.002. Only 52% of the patients who received palliative radiotherapy rated correctly the non-curative intent of treatment, whereas 86% of the patients who received curative radiotherapy made a correct statement. Before radiotherapy, emotional state was often both negatively and positively assessed by the patients. Conclusion: Our short questionnaire is simple and easy to understand. It provides insights into patient information with respect to assessment of the information, satisfaction level, and agreement between

  16. Patient-Reported Outcomes, Patient-Reported Information

    Baldwin, Mike; Spong, Andrew; Doward, Lynda; Gnanasakthy, Ari


    Internet communication is developing. Social networking sites enable patients to publish and receive communications very easily. Many stakeholders, including patients, are using these media to find new ways to make sense of diseases, to find and discuss treatments, and to give support to patients and their caregivers. We argue for a new definition of patient-reported information (PRI), which differs from the usual patient-reported outcomes (PRO). These new emergent data from the social web ha...

  17. Prediction of axillary lymph node metastases in breast cancer patients based on pathologic information of the primary tumor

    Wu, Jia-Long; Tseng, Hsin-Shun; Yang, Li-Heng; Wu, Hwa-Koon; Kuo, Shou-Jen; Chen, Shou-Tung; Chen, Dar-Ren


    Background Axillary lymph nodes (ALN) are the most commonly involved site of disease in breast cancer that has spread outside the primary lesion. Although sentinel node biopsy is a reliable way to manage ALN, there are still no good methods of predicting ALN status before surgery. Since morbidity in breast cancer surgery is predominantly related to ALN dissection, predictive models for lymph node involvement may provide a way to alert the surgeon in subgroups of patients. Material/Methods A t...

  18. Demands on patient information, exemplified by radiotherapy

    Background: Under existing law which goes back to a decision of the supreme court of the German Reich in 1894, any medical intervention, even if performed lege artis and successfully, meets the elements of physical injury both in terms of civil and criminal law and, thus, is illegal. This unlawfulness can only be validly reversed by the patient's informed consent which requires adequate effective patient information. Methods: The relevant principles in patient information on potential risks elaborated by the West German administration of justice are outlined by 22 theses. Subsequently, supreme and highest court decisions are listed, briefly summarizing the jurisdiction on patient information relevant to radiotherapists. Conclusion and Perspectives: tendencies to gain financial profit from improper patient information can be resolutely steered against right from the start. (orig.)

  19. Extracting Information from Electronic Medical Records to Identify the Obesity Status of a Patient Based on Comorbidities and Bodyweight Measures.

    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. PMID:27402260

  20. Knowledge, information and communication among cancer patients

    Objective: Knowledge, information and communication, within oncology, are a core clinical strength for the out-come of the disease and inadequate communication, can cause distress for the patient and their families. Design: A senior doctor conducted this study by filling in the performa after interviewing the subject of the study. Place and duration of study: This study was done in Oncology Department of Service Hospital, Lahore and was completed in four months. Subjects and Method: One hundred cancer patients were interviewed regarding their knowledge about their disease, its causes, prognosis, and information supplied by the health-care providers. They were also asked about their satisfaction regarding this information, deficiencies and pitfalls in this information, need for more information, which should supply the information from among the hospital team or their relative, attitude of the family and their communication regarding the disease. Results: Study revealed that the knowledge about the disease and its causes was present in 53% and 7% respectively. The patients (59%) wanted more information. Majority perceived that the information was not adequate and needed more information and 68% thought that more information would reduce their anxiety. The attitude of family was found encouraging in 87% of patients and 42% were communicating with other family members regarding their diseases. Conclusion: Knowledge about the disease and its cause should be increasingly supplied by the doctors, as it will reduce the anxiety and have a good effect on health. Communication among the family members needs to be improved. (author)

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

    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

  5. Evaluation of internet derived patient information

    Ward, JBM; Leach, P


    INTRODUCTION The internet is a widely used, powerful resource for patients to research medical conditions. There is an extensive amount of information available on the internet. It is important for patient information to be accurate and in an easily accessible format. This article aims to assess the quality of patient information on hydrocephalus and compares the findings with recent evaluations in other surgical specialties. METHODS The term ‘hydrocephalus’ was searched for on the search engines, and The top 20 results of these searches were assessed using the University of Michigan consumer health website evaluation checklist. RESULTS The quality of patient information websites on hydrocephalus is highly variable. Websites rarely provide sufficient authorship information, do not review their information regularly enough and only reference material occasionally. The background of the provider was found to influence the quality of the website, with academic and care providers creating the best websites. CONCLUSIONS On comparing our findings with those of recent studies from other surgical specialties, it was found that there was often a conflict of interest between the background of the provider and the information supplied. It is recommended that clinicians personally research material for their patients to be able to guide them to suitable, accurate websites. PMID:22943222

Most patients (62 %) searched a couple times a year. Online information seeking helped about 2/3 to cope (41 % of the entire sample). About 2/3 did not discuss Internet findings with their doctor. CONCLUSION: Online information seeking helps many patients to...

  7. Towards patient-related information needs.

    Braun, Loes; Wiesman, Floris; van den Herik, Jaap; Hasman, Arie; Korsten, Erik


    The quality of health care depends, among others, on the quality of a physician's domain knowledge. Since it is impossible to keep up with all new findings and developments, physicians usually have gaps in their domain knowledge. To handle exceptional cases, access to the full range of medical literature is required. The specific literature needed for appropriate treatment of the patient is described by a physician's information need. Physicians are often unaware of their information needs. To support them, this paperThis research is part of the MIA project (Medical Information Agent), which is funded by NWO (grant number 634.000.021). aims at presenting a first step towards automatically formulating patient-related information needs. We start investigating how we can model a physician's information needs in general. Then we propose an approach to instantiate the model into a representation of a physician's information needs using the patient data as stored in a medical record. Our experiments show that this approach is feasible. Since the number of formulated patient-related information needs is rather high, we propose the use of filters. Future research will focus on the combination of personalization and filtering. It is expected that the resultant set of information needs will have a manageable size and contributes to the quality of health care. PMID:16160374

  8. Patient Education as an Information System, Healthcare Tool and Interaction

    Pirhonen, Antti; Silvennoinen, Minna; Sillence, Elizabeth


    Patient education (PE) has a crucial role in the function of a healthcare organisation. For the care process of a patient, it is essential to get the right information at the right moment and in the right form. This paper analyses PE as the primary mode of interaction between a patient and a healthcare organisation. The approach is illustrated with a study among nurses based on their conceptions about PE. Practical implications and the potential of ICT in PE in particular are discussed.

  10. Informed patient consent: a historical perspective.

    Dowd, S B; Wilson, B


    This article reviews the concept of informed patient consent by examining two long-term studies in which adequate consent was not obtained from study participants: the radiation experiments sponsored by the U.S. government beginning in the 1940s and the Tuskegee Syphilis Experiment conducted from 1932 to 1972. The article discusses how these experiments represent a violation of informed consent guidelines and research ethics. It also explores the ethical implications of the experiments to radiologic technologists today and discusses the technologist's role in obtaining patient consent in research and clinical practice settings.

  11. Accessing Patient Information for Probabilistic Patient Models Using Existing Standards.

    Gaebel, Jan; Cypko, Mario A; Lemke, Heinz U


    Clinical decision support systems (CDSS) are developed to facilitate physicians' decision making, particularly for complex, oncological diseases. Access to relevant patient specific information from electronic health records (EHR) is limited to the structure and transmission formats in the respective hospital information system. We propose a system-architecture for a standardized access to patient specific information for a CDSS for laryngeal cancer. Following the idea of a CDSS using Bayesian Networks, we developed an architecture concept applying clinical standards. We recommend the application of Arden Syntax for the definition and processing of needed medical knowledge and clinical information, as well as the use of HL7 FHIR to identify the relevant data elements in an EHR to increase the interoperability the CDSS.

  12. Wikipedia and osteosarcoma: a trustworthy patients' information?

    Leithner, Andreas; Maurer-Ertl, Werner; Glehr, Mathias; Friesenbichler, Joerg; Leithner, Katharina; Windhager, Reinhard


    The English version of the online encyclopedia, Wikipedia, has been recently reported to be the prominent source of online health information. However, there is little information concerning the quality of information found in Wikipedia. Therefore, we created a questionnaire asking for scope, completeness, and accuracy of information found on osteosarcoma. Three independent observers tested the English version of Wikipedia, as well as the patient version and the health professional version of the US National Cancer Institute (NCI) website. Answers were verified with authoritative resources and international guidelines. The results of our study demonstrate that the quality of osteosarcoma-related information found in the English Wikipedia is good but inferior to the patient information provided by the NCI. Therefore, non-peer-reviewed commonly used websites offering health information, such as Wikipedia, should include links to more definitive sources, such as those maintained by the NCI and professional international organizations on healthcare treatments. Furthermore, frequent checks should make sure such external links are to the highest quality and to the best-maintained aggregate sites on a given healthcare topic. PMID:20595302

  13. A Patient Safety Information Model for Interoperability.

    Rodrigues, Jean Marie; Dhingra-Kumar, Neelam; Schulz, Stefan; Souvignet, Julien


    Current systems that target Patient Safety (PS) like mandatory reporting systems and specific vigilance reporting systems share the same information types but are not interoperable. Ten years ago, WHO embarked on an international project to standardize quality management information systems for PS. The goal is to support interoperability between different systems in a country and to expand international sharing of data on quality and safety management particularly for less developed countries. Two approaches have been used: (i) a bottom-up one starting with existing national PS reporting and international or national vigilance systems, and (ii) a top-down approach that uses the Patient Safety Categorial Structure (PS-CAST) and the Basic Formal Ontology (BFO) upper level ontology versions 1 and 2. The output is currently tested as an integrated information system for quality and PS management in four WHO member states. PMID:27139388

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

    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

  15. Isotope-based quantum information

    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...

In other emerging concepts, the control of the spatial distribution of isotopes with nuclear spins is a prerequisite to implement the quantum bits (or qbits). Therefore, stable semiconductor isotopes are important elements in the development of solid-state quantum information. There are not only different algorithms of quantum computation discussed but also the different models of quantum computers are presented. With numerous illustrations this small book is of great interest for undergraduate students taking courses in mesoscopic physics or nanoelectronics as well as quantum information, and academic and industrial researches working in this field.

  17. Aelius Aristides as Informed Patient and Physician.

    Petridou, Georgia


    Aelius Aristides, one of the most renowned orators of the so-called second sophistic, has often been thought of as the paradigmatic patient who surrendered his physical and psychological health to Asclepius, and spent a large part of his life in the temple of the god at Pergamum blindly following divine orders on diet and regimen. This study looks at the Hieroi Logoi as an illness narrative and argues against such a simplistic view and in favour of a more complex picture: Aristides is a far cry far from the submissive patient, who idly resided in the Pergamene Asclepieion relying exclusively on the therapeutic powers of the god and his human helpers. In fact, through a close reading of a selection of passages from the Hieroi Logoi a whole new image of Aristides emerges: the informed patient who is not only in possession of the basics of the medical discourse but who also functions as a physician of sorts, taking both his own life and the lives of others into his hands. This new type of patient, the knowledgeable patient, who is well-versed in medical matters and envisages himself as an active agent of the healing process and an equally important partner in the medical encounter, ties well with other testimonies we have about knowledgeable patients mostly to be found amongst the members of the socio-political elite of the time.

    This is the second article in a seven-part series demonstrating the value of analysing patient narratives in nursing and nurse education. Part 1 reviewed the evidence regarding the use of narrative and focused on unintended communication. This article draws on a story exploring consent and capacity, and demonstrates the lessons that can be learnt for all fields of nursing. We hope your reflections on the narratives will help to inform your professional practice and provide evidence for revalidation. PMID:27145672

  19. Informal patient payments in oncology practice

    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.

  20. [Quality control of printed patient information].

    Herm, Kerstin; Linden, Michael


    Printed material is an important part in patient information and is called bibliotherapy. It is subject to quality control similar to any other types of treatment. This paper presents an outline of important quality criteria and methods of quality control. Important quality criteria are: (a) Correctness and validity of content evaluated by mentioning the expertise of the authors, appraisal through external experts, reference to scientific literature, and empirical tests of the content, (b) Readability in respect to text structure measured by the "Flesch-Reading-Ease-Formula" supported by fair graphical design including fond and structure of text, (c) Comprehensibility tested by feedback of patients or standardized by the Hamburg comprehensibility rating, (d) Utility including securing availability, acceptance, differential indication and use. Writing and publication of patient leaflets must be accompanied by quality control measures. PMID:23446824

  1. Information based universal feature extraction

    Amiri, Mohammad; Brause, Rüdiger


    In many real world image based pattern recognition tasks, the extraction and usage of task-relevant features are the most crucial part of the diagnosis. In the standard approach, they mostly remain task-specific, although humans who perform such a task always use the same image features, trained in early childhood. It seems that universal feature sets exist, but they are not yet systematically found. In our contribution, we tried to find those universal image feature sets that are valuable for most image related tasks. In our approach, we trained a neural network by natural and non-natural images of objects and background, using a Shannon information-based algorithm and learning constraints. The goal was to extract those features that give the most valuable information for classification of visual objects hand-written digits. This will give a good start and performance increase for all other image learning tasks, implementing a transfer learning approach. As result, in our case we found that we could indeed extract features which are valid in all three kinds of tasks.

  3. Sound source information to improve cardiothoracic patients' comfort.

    Mackrill, Jamie; Cain, Rebecca; Jennings, Paul; England, Michelle

    Hospital sound has been well documented through acoustic measurement and the classification of its adverse effects on patients and nurses. However, little consideration has been given to how the perception of these unavoidable soundscapes can be improved. For instance, does a better understanding of the variety of sounds improve patients' feeling? This paper begins to answer this and documents a pilot questionnaire-based study looking at the effects and potential benefits of sound source information (SSI) on patients' subjective reactions to a ward soundscape. The study was carried out from July to September 2011 with 31 patients in a cardiothoracic ward. Although strong inferences were not made, it was found that this simple intervention created a 21-26% positive change perception (pcomfortable. PMID:23588015

  4. Knowledge, mistakes, communication with patients and informed consent

    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.

    In contrast to existing computerized patient record systems, which merely offer static functionality for storage and presentation, a helpful patient record system is a problem-oriented, knowledge-based system which provides the clinician with situation-specific information from the patient record, relevant to the activity within the patient care process. We suggest extending the data model of current patient record systems with (1) knowledge for recognizing and interpreting care situations, (...

    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.

  7. Informing cancer patient in relation to his type of personality: the emotional-hyperthymic (dramatizing) patient.

    Kallergis, G


    Informing a cancer patient has been an issue of particular interest to the scientific community over the last 50 years. Since 1989 we have been studying the characters or personality types based on the Kahana and Bibring's approach as part of Consultation-Liaison (C-L) Psychiatry. The question posed was how these characters or personality types could be useful in the process of informing the cancer patient. The aim of this paper was to describe the emotional-hyperthymic character or type of personality thoroughly, so that any physician can make a diagnosis and tailor the information strategy to the patient's needs. The qualitative method of research through groups with doctors and nurses was used, while the research within groups lasted for 5 years. The degree of patients' denial varied between "large" and "very large" and sometimes was "medium". Initially, the degree of information was "minimal", then "small" until it reached "medium". A discordance was evident between what the patient showed and what the family reported about him. The patient presented himself as courageous and extrovert, but the relatives considered him as faint-hearted. PMID:22331735

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

    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

  9. A Web-Based Psychoeducational Program for Informal Caregivers of Patients With Alzheimer’s Disease: A Pilot Randomized Controlled Trial

    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

  10. Effective information spreading based on local information in correlated networks

    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...

  12. Informal information for web-based engineering catalogues

    Allen, Richard D.; Culley, Stephen J.; Hicks, Ben J.


    Success is highly dependent on the ability of a company to efficiently produce optimal designs. In order to achieve this companies must minimize time to market and possess the ability to make fully informed decisions at the early phase of the design process. Such decisions may include the choice of component and suppliers, as well as cost and maintenance considerations. Computer modeling and electronic catalogues are becoming the preferred medium for the selection and design of mechanical components. In utilizing these techniques, the designer demands the capability to identify, evaluate and select mechanical components both quantitatively and qualitatively. Quantitative decisions generally encompass performance data included in the formal catalogue representation. It is in the area of qualitative decisions that the use of what the authors call 'Informal Information' is of crucial importance. Thus, 'Informal Information' must often be incorporated into the selection process and selection systems. This would enable more informed decisions to be made quicker, without the need for information retrieval via discussion with colleagues in the design environment. This paper provides an overview of the use of electronic information in the design of mechanical systems, including a discussion of limitations of current technology. The importance of Informal Information is discussed and the requirements for association with web based electronic catalogues are developed. This system is based on a flexible XML schema and enables the storage, classification and recall of Informal Information packets. Furthermore, a strategy for the inclusion of Informal Information is proposed, and an example case is used to illustrate the benefits.

  16. Recommendations for responsible monitoring and regulation of clinical software systems. American Medical Informatics Association, Computer-based Patient Record Institute, Medical Library Association, Association of Academic Health Science Libraries, American Health Information Management Association, American Nurses Association.

    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. PMID:9391932

  17. How health information is received by diabetic patients?

    Firoozeh Zare-Farashbandi


    Full Text Available Background: Knowledge of correct information-seeking behavior by the patients can provide health specialists and health information specialists with valuable information in improving health care. This study aimed to investigate the passive receipt and active seeking of health information by diabetic patients. Materials and Methods: A survey method was used in this research on 6426 diabetic patients of whom 362 patients were selected by a no percentage stratified random sampling. The Longo information-seeking behavior questionnaire was used to collect data and they were analyzed by SPSS 20 software. Results: The most common information source by diabetic patients was practitioners (3.12. The minimum usage among the information sources were from charity organizations and emergency phone lines with a usage of close to zero. The amount of health information gained passively from each source has the lowest average of 4.18 and usage of this information in making health decision has the highest average score of 5.83. Analysis of the data related to active seeking of information showed that knowledge of available medical information from each source has the lowest average score of 3.95 and ability in using the acquired information for making medical decisions has the highest average score of 5.28. The paired t-test showed that differences between passive information receipt (41.68 and active information seeking (39.20 considered as statistically significant (P < 0.001. Conclusion: Because diabetic patients are more passive information receivers than active information seekers, the health information must be distributed by passive means to these patients. In addition, information-seeking behavior during different time periods should be investigated; to identify more effective distribution of health information.

The nature of the responses, the patients' motivation and expectations, the degree of patient awareness regarding the planne...

  1. Imaging based, patient specific dosimetry

    that this can be performed is either by sequential planar scintillation camera measurements or by SPECT methods. Scintillation cameras generally have a low spatial resolution and sensitivity (cps/MBq) due to the collimator. The resolution is in order of 1-2 cm depending on the source location and radionuclide characteristics. Image noise is also a major problem since only a small activity is given for pre-planning which can degrade the image quality. Dosimetry using 2D planar imaging and the conjugate-view activity quantitation method have been used for many years. The quantification of the activity includes several approximations. In a planar acquisition the source depth in the patient is not resolved which makes the correction for photon attenuation and unwanted contribution from scattered photons to the image less accurate and consistent. Furthermore, contributions from activity uptakes that overlap the volume of interest in the image is a major problem. For calculation of the absorbed dose, the organ mass also needs to be determined, which can be made using patient CT images, or, using less accurate estimations from standardized phantom geometries. The energy deposition and transport is done based on pre-calculated dose factors from standardized phantom geometries. Despite these problems, the conjugate-view method has been the major choice for many dosimetrical studies. SPECT provide a possibility for 3D activity measurements. In this method, correction for non-homogeneous photon attenuation, scatter and loss of spatial resolution due to the collimator are today quite accurate when incorporated in iterative reconstruction methods. SPECT also allows for an accurate 3D absorbed dose calculation in that the patient's geometry can be taken into consideration if a co-registered CT study of the patient is available. Modern hybrid SPECT/CT cameras make such calculations relatively straight-forward. A major advantage using SPECT imaging is also that the absorbed dose

  2. Spatial Information Based Medical Image Registration using Mutual Information

    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.

    At present, network information audit system is almost based on text information filtering, but badness information is embedded into image or image file directly by badness information provider, in order to avoid monitored by. The paper realizes an information audit system based on image content filtering. Taking the pornographic program identification for an example, the system can monitor the video including any abnormal human body information by matching the texture characters with those defined in advance, which consist of contrast, energy, correlation measure and entropy character measure and so on.


    Pedro Luiz Cortês


    Full Text Available The importance of patient records, also known as medical records, is related to different needs and objectives, as they constitute permanent documents on the health of patients. With the advancement of information technologies and systems, patient records can be stored in databases, resulting in a positive impact on patient care. Based on these considerations, a research question that arises is “what are the benefits and problems that can be seen with the use of electronic versions of medical records?” This question leads to the formulation of the following hypothesis: although problems can be identified during the process of using electronic record systems, the benefits outweigh the difficulties, thereby justifying their use. To respond to the question and test the presented hypothesis, a research study was developed with users of the same electronic record system, consisting of doctors, nurses, and administrative personnel in three hospitals located in the city of São Paulo, Brazil. The results show that, despite some problems in their usage, the benefits of electronic patient records outweigh possible disadvantages.

  9. Patients' need for information prior to colonic surgery.

    Sjöstedt, Lisbeth; Hellström, Renee; Stomberg, Margareta Warrén


    Perioperative information and communication between patients and health professionals is central to the quality of care and patient involvement for elective colon surgery. Enhanced recovery after surgery (ERAS) means that the care process is accelerated with comprehensive information and additional requirements on an individual. The purpose of this study was to identify nurses' and doctors' experience of patients' need for information before intraoperative care. Nurses (n = 39) with different specialties and professional experience were interviewed in focus groups. Ten anesthesiologists with differing professional experience were interviewed individually. Data were analyzed with qualitative content analysis. The result shows the need to provide information to reduce anxiety, to make the patient feel safe, to explain postoperative pain management, and to provide a comprehensive care pathway. There was no difference between the informants' perception of patients' information needs. All respondents agreed that patients generally have a great need for information. The perioperative information should be repeated at different points in time. The patients' need for information on diagnosis is recurrent. Knowledge, good communication, and attitude from a multiprofessional perspective support the patient's feeling comfortable and involved in the care prior to surgery. PMID:21979401

  10. [The information of the schizophrenic patient: actuality].

    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. PMID:15959449

  11. Image matching navigation based on fuzzy information

    田玉龙; 吴伟仁; 田金文; 柳健


    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.

  13. OPIC: Ontology-driven Patient Information Capturing system for epilepsy.

    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.

  15. Patient autonomy and relatives' right to know genetic information.

    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. PMID:18284110

  18. An assessment of the preoperative information given to patients in the province of Karaman

    Ali Şahin


    Full Text Available The purpose of this research was to determine the status of information provision for patients in the preoperative period. Two hundred fifty patients undergoing surgery in the Karaman Public Hospital. A questionnaire prepared by the authors based on information in the literature and consisting of questions intended to determine patients’ sociodemographic characteristics and the preoperative provision of information was used as a data collection tool. Data were expressed as number, percentage, mean and standard deviation. Mean age of patients was 45±21.08 years. We determined that 47.2% had been given information concerning preoperative procedures and preoperative preparations, and that 7.6% had been given this information by nurses. In the light of the study findings, we conclude that physicians and nurses need to be more proactive in providing patients with preoperative information and that, considering the forgetfulness factor, such information should also be provided in written form.

    The quality of patient care is critically influenced by the availability of accurate information and its efficient management. Radiation oncology consists of many information components, for example there may be information related to the patient (e.g., profile, disease site, stage, etc.), to people (radiation oncologists, radiological physicists, technologists, etc.), and to equipment (diagnostic, planning, treatment, etc.). These different data must be integrated. A comprehensive informatio...

  3. Painters and patients: how art informs medicine.

    Wear, D


    This essay describes three movements in art--impressionism, cubism, and abstract expressionism--and how artists within each movement differed in their portrayal of reality. With this background, the author proposes that inquiry into the motives and methods of artists within each movement may help in our understanding of how a person experiences, interprets, and portrays reality. This, in turn, may translate into a recognition of the multiplicity of perspectives and the uniqueness of each patient's lived experience of his or her illness and that the doctor's vantage point on reality may not mesh with that of the patient.

  4. Context based multimedia information retrieval

    Mølgaard, Lasse Lohilahti; Hansen, Lars Kai; Larsen, Jan


    The large amounts of digital media becoming available require that new approaches are developed for retrieving, navigating and recommending the data to users in a way that refl ects how we semantically perceive the content. The thesis investigates ways to retrieve and present content for users with the help of contextual knowledge. Our approach to model the context of multimedia is based on unsupervised methods to automatically extract meaning. We investigate two paths of context modelling. T...

    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.




    Full Text Available OBJECTIVE: Surgeries are seen as stressors that activate preoperative fear. Preparing the patients prior to surgery through preoperative instruction develop crucial to anxiety level. The objective of study is to evaluate the perception of patients regarding anxiety prior to surgery. M ETHODS : A total of 273 patients attending the outpatient department of Hospital were taken in the study. All the patients were aged 20 - 60 years. The anxiety was measured by means of different questions like fear of surgery, pain due to surgery, postoperati ve complication, preoperative information of surgery etc. Student’s t - test, one - way ANOVA was performed to obtain the mean values of anxiety using SPSS 16.0 for Windows. RESULTS: It was found that all of the patients received preoperative information about the surgery to be done and most of them obtained information from doctors ( 27.6%, hospital management staff ( 24.3%, and nurses ( 22.5%. Fear of surgery ( 18.6% and pain ( 17.4% are most common factors among study participants. Significant results of anx iety was found with educational level and age ( p=0.000. CONCLUSION: All the patients got information prior to the surgery and main source of information were doctors, hospital management staff and nurses. Mostly patients were anxious of surgery and post - operative pain. Still, health professionals should plan to deliver appropriate information to help patients against this fear.

  7. Information-time based futures pricing

    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.

  8. [Verbal patient information through nurses--a case of stroke 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. PMID:15281356

  10. Informal caregivers of patients with COPD: Home Sweet Home?

    Nienke Nakken


    Full Text Available The burden of chronic obstructive pulmonary disease (COPD on society is increasing. Healthcare systems should support patients with COPD in achieving an optimal quality of life, while limiting the costs of care. As a consequence, a shift from hospital care to home care seems inevitable. Therefore, patients will have to rely to a greater extent on informal caregivers. Patients with COPD as well as their informal caregivers are confronted with multiple limitations in activities of daily living. The presence of an informal caregiver is important to provide practical help and emotional support. However, caregivers can be overprotective, which can make patients more dependent. Informal caregiving may lead to symptoms of anxiety, depression, social isolation and a changed relationship with the patient. The caregivers' subjective burden is a major determinant of the impact of caregiving. Therefore, the caregiver's perception of the patient's health is an important factor. This article reviews the current knowledge about these informal caregivers of patients with COPD, the impact of COPD on their lives and their perception of the patient's health status.

    Wu, Shengjun; Yu, Sixia; Mølmer, Klaus


    We discuss quantitatively the complementarity of information transmitted by a quantum system prepared in a basis state in one out of several different mutually unbiased bases (MUBs). We obtain upper bounds on the information available to a receiver who has no knowledge of which MUB was chosen by...... the sender. These upper bounds imply a complementarity of information encoded via different MUBs and ultimately ensure the security in quantum key distribution protocols....

  14. Designing Patient-facing Health Information Technologies for the Outpatient Settings: A Literature Review

    Yushi Yang


    Full Text Available Introduction: The implementation of health information technologies (HITs has changed the dynamics of doctor–patient communication in outpatient settings. Designing patient-facing HITs provides patients with easy access to healthcare information during the visit and has the potential to enhance the patient-centred care.   Objectives: The objectives of this study are to systematically review how the designs of patient-facing HITs have been suggested and evaluated, and how they may potentially affect the doctor–patient communication and patient-centred care.   Method: We conducted an online database search to identify articles published before December 2014 relevant to the objectives of this study. A total of nine papers have been identified and reviewed in this study.   Results: Designing patient-facing HITs is at an early stage. The current literature has been exploring the impact of HITs on doctor–patient communication dynamics. Based on the findings of these studies, there is an emergent need to design more patient-centred HITs. There are also some papers that focus on the usability evaluation of some preliminary prototypes of the patient-facing HITs. The design styles of patient-facing HITs included sharing the health information with the patients on: (1 a separate patient display, (2 a projector, (3 a portable tablet, (4 a touch-based screen and (5 a shared computer display that can be viewed by both doctors and patients. Each of them had the strengths and limitations to facilitate the patient-centred care, and it is worthwhile to make a comparison of them in order to identify future research directions.   Conclusion: The designs of patient-facing HITs in outpatient settings are promising in facilitating the doctor-patient communication and patient engagement. However, their effectiveness and usefulness need to be further evaluated and improved from a systems perspective.

  16. Parallel Patient Karyotype Information System using Multi-threads



    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.

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

    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.

  18. Patient Preferences for Information on Post-Acute Care Services.

    Sefcik, Justine S; Nock, Rebecca H; Flores, Emilia J; Chase, Jo-Ana D; Bradway, Christine; Potashnik, Sheryl; Bowles, Kathryn H


    The purpose of the current study was to explore what hospitalized patients would like to know about post-acute care (PAC) services to ultimately help them make an informed decision when offered PAC options. Thirty hospitalized adults 55 and older in a Northeastern U.S. academic medical center participated in a qualitative descriptive study with conventional content analysis as the analytical technique. Three themes emerged: (a) receiving practical information about the services, (b) understanding "how it relates to me," and (c) having opportunities to understand PAC options. Study findings inform clinicians what information should be included when discussing PAC options with older adults. Improving the quality of discharge planning discussions may better inform patient decision making and, as a result, increase the numbers of patients who accept a plan of care that supports recovery, meets their needs, and results in improved quality of life and fewer readmissions.

  19. Agent Based Patient Scheduling Using Heuristic Algorithm

    Juliet A Murali


    Full Text Available This paper describes about an agent based approach to patient scheduling using experience based learning. A heuristic algorithm is also used in the proposed framework. The evaluation on different learning techniques shows that the experience based learning (EBL gives better solution. The processing time decreases as the experience increases. The heuristic algorithm make use of EBL in calculating the processing time. The main objective of this patient scheduling system is to reduce the waiting time of patient in hospitals and to complete their treatment in minimum required time. The framework is implemented in JADE. In this approach the patients and resources are represented as patient agents (PA and resource agents (RA respectively. Even though mathematical model give optimal solution, the computational complexity increases for large size problems. Heuristic solution gives better solution for large size problems. The comparisons of the proposed framework with other scheduling rules shows that an agent based approach to patient scheduling using EBL is better.

  20. Matchmaking Semantic Based for Information System Interoperability

    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...

  1. Information on actual medication use and drug-related problems in older patients: questionnaire or interview?

    Willeboordse, Floor; Grundeken, Lucienne H; van den Eijkel, Lisanne P; Schellevis, François G; Elders, Petra J M; Hugtenburg, Jacqueline G


    Background Information on medication use and drug-related problems is important in the preparation of clinical medication reviews. Critical information can only be provided by patients themselves, but interviewing patients is time-consuming. Alternatively, patient information could be obtained with a questionnaire. Objective In this study the agreement between patient information on medication use and drug-related problems in older patients obtained with a questionnaire was compared with information obtained during an interview. Setting General practice in The Netherlands. Method A questionnaire was developed to obtain information on actual medication use and drug-related problems. Two patient groups ≥65 years were selected based on general practitioner electronic medical records in nine practices; I. polypharmacy and II. ≥1 predefined general geriatric problems. Eligible patients were asked to complete the questionnaire and were interviewed afterwards. Main outcome measure Agreement on information on medication use and drug-related problems collected with the questionnaire and interview was calculated. Results Ninety-seven patients participated. Of all medications used, 87.6 % (95 % CI 84.7-90.5) was reported identically in the questionnaire and interview. Agreement for the complete medication list was found for 45.4 % (95 % CI 35.8-55.3) of the patients. On drug-related problem level, agreement between questionnaire and interview was 75 %. Agreement tended to be lower in vulnerable patients characterized by ≥4 chronic diseases, ≥10 medications used and low health literacy. Conclusion Information from a questionnaire showed reasonable agreement compared with interviewing. The patients reported more medications and drug-related problems in the interview than the questionnaire. Taking the limitations into account, a questionnaire seems a suitable tool for medication reviews that may replace an interview for most patients. PMID:26830412

  2. Quality of Web-based information systems

    Kazimierz Worwa


    Full Text Available The scope and complexity of current World Wide Web applications vary widely: from smallscale, short-lived services to large-scale enterprise applications distributed across the Internet and corporate intranets and extranets. As Web applications have evolved, the demands placed on Web-based systems and the complexity of designing, developing, maintaining, and managing these systems have also increased significantly. They provided vast, dynamic information in multiple media formats (graphics, images, and video. Web site design for these and many other applications demand balance among information content, aesthetics, and performance. In accordance with the growth of the Internet and World Wide Web, there has been some research on quality issues of Web-based software systems. The differences between the Web-based information systems and conventional information systems are discussed in a paper from the perspective of software quality

  3. Patient information provision: its effect on patient anxiety and the role of health information services and libraries.

    Bolton, V; Brittain, M


    This article is concerned with the importance of communicating information to patients as an aid to recovery by decreasing anxiety. Recent research suggests that pre-operative information helps to decrease post-operative stress and leads to a quicker recovery. The health belief model has proven to be an effective predictor of individuals' responses towards health-related matters. It is described as a useful theoretical framework for medical professionals in deciding the content and quantity of information that each patient should receive. A study for further research is suggested, exploring the hypothesis that reading about illness significantly helps to reduce anxiety when the patient has added emotional support from a health professional. The existing problem of who is ultimately responsible for giving information to patients is highlighted in the general practice, hospital and public settings. Recommendations are made for the improvement of patient information provision in these three areas. Librarians are seen as being in a good position to liaise with medical professionals to provide the most effective health information service possible for patients and the consumer in general.

  4. Internet chemotherapy information: impact on patients and health professionals

    Davies, E; Yeoh, K-W


    Background: Reliable information can improve patients' knowledge of chemotherapy. As internet chemotherapy information (ICI) is increasingly viewed as a valuable patient education tool, we investigated the impact of ICI on patient care and analysed health professionals' (HPs') attitudes towards ICI. Methods: The following questionnaires were distributed: (1) self-administered questionnaire randomly given to 261 patients receiving chemotherapy (80% returned); and (2) separate questionnaire given to 58 HPs at the same UK Oncology Centre (83% returned). Results: Just over half of the patient respondents accessed the internet regularly. They were younger, with higher incomes and qualifications. Key search topics included chemotherapy modes of action, symptom management and treatment success, and most considered ICI useful. More than half wanted to discuss ICI with HPs but most did not get the opportunity. Although the majority of HP respondents supported the need for patients to retrieve ICI, most questioned the accuracy of ICI and did not routinely recommend its use. Conclusion: This study has shown that ICI is generally perceived by patients to be a valuable information resource. Given the potential impact of ICI, the following should be addressed in future studies: (1) inequalities in accessing ICI; (2) maintaining the quality of ICI (with clear guidance on recommended websites); (3) bridging the gap between the perception of ICI by patients and HPs; (4) integration of ICI with traditional consultation models. PMID:22262319

  5. Patient information about radiation therapy: a survey in Europe

    Background and purpose: We performed a survey to evaluate the present status and means of information given to patients treated by radiotherapy. A short questionnaire was sent, with the help of ESTRO, to 746 European heads of department with a request to send specific documents used for informing the patient. Within 2 months (March and April 1996) we received 290 answers (39%) and 97 centres sent documents. Materials and methods: Analysis of the questionnaire and the documents was performed quantitatively with usual statistical methods and qualitatively with a socio-anthropological method of content analysis. Results: Analysis of the questionnaire shows the major role of the radiation oncologist in giving information and writing documents. The 298 different samples sent from 97 centres represent a wide panel with a booklet of general information (59 booklets/57 centres), practical advice and specific explanations (177 documents/49 centres) and informed consent (36 documents/28 centres). The anthropological study was centred on the way information was given, evaluation of the patient's understanding and analysis of documents sent. Conclusion: This preliminary survey needs to be completed by a study, including the patient's point of view and needs, about the information given

  6. Systematic Review of Quality of Patient Information on Liposuction in the Internet

    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.

  7. Image Filtering Based on Improved Information Entropy

    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

    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.

  9. Giving information to family members of patients in the intensive care unit: Iranian nurses' ethical approaches.

    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. PMID:25512830

  10. RFID based patient registration in mass casualty incidents

    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.

    A new information integration platform for computer integrated manufacturing system(CIMS) is presented, which is based on agent and CORBA. CORBA enhances the system integration be-cause it is an industry-standard for interoperable, distributed objects across heterogeneous hardware andsoftware platform. Agent technology is used to improve intelligence of integration system. In order to im-plement the information integration platform, we use network integration server to integrate network, de-sign a generic database agent to integrate database, adopt multi-agent based architecture to integrate appli-cation, and utilize wrapper as CORBA object to integrate legacy code.

  12. Adherence to oral anticoagulants in patients with atrial fibrillation—a population-based retrospective cohort study linking health information systems in the Valencia region, Spain: a study protocol

    Sanfélix-Gimeno, G; Rodríguez-Bernal, C L; Hurtado, I; Baixáuli-Pérez, C; Librero, J; Peiró, S


    Introduction Adherence to oral anticoagulation (OAC) treatment, vitamin K antagonists or new oral anticoagulants, is an essential element for effectiveness. Information on adherence to OAC in atrial fibrillation (AF) and the impact of adherence on clinical outcomes using real-world data barely exists. We aim to describe the patterns of adherence to OAC over time in patients with AF, estimate the associated factors and their impact on clinical events, and assess the same issues with conventional measures of primary and secondary adherence—proportion of days covered (PDC) and persistence—in routine clinical practice. Methods and analysis This is a population-based retrospective cohort study including all patients with AF treated with OAC from 2010 to date in Valencia, Spain; data will be obtained from diverse electronic records of the Valencia Health Agency. Primary outcome measure: adherence trajectories. Secondary outcomes: (1) primary non-adherence; (2) secondary adherence: (a) PDC, (b) persistence. Clinical outcomes: hospitalisation for haemorrhagic or thromboembolic events and death during follow-up. Analysis: (1) description of baseline characteristics, adherence patterns (trajectory models or latent class growth analysis models) and conventional adherence measures; (2) logistic or Cox multivariate regression models, to assess the associations between adherence measures and the covariates, and logistic multinomial regression models, to identify characteristics associated with each trajectory; (3) Cox proportional hazard models, to assess the relationship between adherence and clinical outcomes, with propensity score adjustment applied to further control for potential confounders; (4) to estimate the importance of different healthcare levels in the variations of adherence, logistic or Cox multilevel regression models. Ethics and dissemination This study has been approved by the corresponding Clinical Research Ethics Committee. We plan to disseminate the

  13. 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...

  14. Cognitive Function in Patients Undergoing Arthroplasty: The Implications for Informed Consent

    N. Demosthenous


    Full Text Available Obtaining informed consent for an operation is a fundamental daily interaction between orthopaedic surgeon and patient. It is based on a patient's capacity to understand and retain information about the proposed procedure, the potential consequences of having it, and the alternative options available. We used validated tests of memory on 59 patients undergoing lower limb arthroplasty to assess how well they learned and recalled information about their planned procedure. All patients showed an ability to learn new material; however, younger age and higher educational achievement correlated with better performance. These results have serious implications for orthopaedic surgeons discussing planned procedures. They identify groups of patients who may require enhanced methods of communicating the objectives, risks, and alternatives to surgery.

  16. Informal, Incidental and Ad Hoc: The Information-Seeking and Learning Strategies of Health Care Patients

    Papen, Uta


    When people are ill, they want to know what is happening to them and how they can get better. Current health policies support patients' access to health information and encourage them to take part in decisions regarding their health. But little is known about how patients learn and the difficulties they may encounter in the process. This paper…

  17. Giving information to family members of patients in the intensive care unit: Iranian nurses’ ethical approaches

    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. PMID:25512830

  1. Orthognathic surgery: is patient information on the Internet valid?

    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. PMID:21459834

  2. Navigating the cancer information environment: The reciprocal relationship between patient-clinician information engagement and information seeking from nonmedical sources

    Moldovan-Johnson, Mihaela; Tan, Andy SL; 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 one-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 to clinician sources in a dynamic way to learn about their disease. PMID:24359259

  3. Sensor management based on fisher information gain

    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.

  6. Canonical analysis based on mutual information

    Nielsen, Allan Aasbjerg; Vestergaard, Jacob Schack


    Canonical correlation analysis (CCA) is an established multi-variate statistical method for finding similarities between linear combinations of (normally two) sets of multivariate observations. In this contribution we replace (linear) correlation as the measure of association between the linear...... combinations with the information theoretical measure mutual information (MI). We term this type of analysis canonical information analysis (CIA). MI allows for the actual joint distribution of the variables involved and not just second order statistics. While CCA is ideal for Gaussian data, CIA facilitates...... analysis of variables with different genesis and therefore different statistical distributions and different modalities. As a proof of concept we give a toy example. We also give an example with one (weather radar based) variable in the one set and eight spectral bands of optical satellite data in the...

  12. STB Based Multimedia Information Publication System

    Xuan Li


    Full Text Available The development of communication network has promoted the development of network multimedia. Nowadays, multimedia information can be displayed in various ways. Therefore, an efficient publication system is very necessary for users to distribute and display multimedia content fast and efficiently. To satisfy user's requirement, the set-top box (STB based multimedia publication system is designed and implemented. The STB based system proposed in this paper adopted distributed B/S architecture, which is reasonably divided into five modules according to their own functions, consisting of information center, sharing database, time-sharing distribute engine, group controller and STB terminals. The performance and flexibility of this framework is very favorable. Its control logic is separated from physical time-sharing data transmission, in order to improve scalability and reliability. Data transmission is optimized to support a large number of terminals with special algorithms. Time-sharing engine is used to improve robustness of system when sources exceed the capacity of STB.  Evaluation result shows that the system designed in this paper can provide high-quality information display services for terminal users with a relative low hardware cost. The kind of information publication system has been applied in retail stores, restaurants in Shanghai, Beijing and Nigeria.

  13. Heterogeneous information-based artificial stock market

    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.

  17. Towards a new kind of patient information leaflet?

    Fage-Butler, Antoinette Mary

    There is general consensus amongst patients, academics and regulatory agencies that mandatory PILs, which accompany all medication in the EU, do not communicate effectively with patients. This is problematic as patients have stated that they want to receive information on their medication; they are...... needs adequately. Trust has been linked to successful risk communication in the literature, and according to trust theory, trust may be a byproduct of discourses of care, whereby receivers’ needs are met. The dissertation is an example of applied research, seeking to identify possible solutions to...... applicability: it should help to support the writing of more patient centered PILs. Of course, consideration would need to be given to how these statement functions could convert into expressions in PILs, as statement functions relate to Discourse (Gee, 1996, p.6), rather than to language.

  18. Development of an electronic radiation oncology patient information management system

    Mandal Abhijit


    Full Text Available The quality of patient care is critically influenced by the availability of accurate information and its efficient management. Radiation oncology consists of many information components, for example there may be information related to the patient (e.g., profile, disease site, stage, etc., to people (radiation oncologists, radiological physicists, technologists, etc., and to equipment (diagnostic, planning, treatment, etc.. These different data must be integrated. A comprehensive information management system is essential for efficient storage and retrieval of the enormous amounts of information. A radiation therapy patient information system (RTPIS has been developed using open source software. PHP and JAVA script was used as the programming languages, MySQL as the database, and HTML and CSF as the design tool. This system utilizes typical web browsing technology using a WAMP5 server. Any user having a unique user ID and password can access this RTPIS. The user ID and password is issued separately to each individual according to the person′s job responsibilities and accountability, so that users will be able to only access data that is related to their job responsibilities. With this system authentic users will be able to use a simple web browsing procedure to gain instant access. All types of users in the radiation oncology department should find it user-friendly. The maintenance of the system will not require large human resources or space. The file storage and retrieval process would be be satisfactory, unique, uniform, and easily accessible with adequate data protection. There will be very little possibility of unauthorized handling with this system. There will also be minimal risk of loss or accidental destruction of information.

    Full Text Available Introduction: Oncology patients need extensive follow-up and meticulous documentation. The aim of this study was to introduce a simple, platform independent file based system for documentation of diagnostic and therapeutic procedures in oncology patients and test its function.Material and methods: A file-name based system of the type M1M2M3.F2 was introduced, where M1 is a unique identifier for the patient, M2 is the date of the clinical intervention/event, M3 is an identifier for the author of the medical record and F2 is the specific software generated file-name extension.Results: This system is in use at 5 institutions, where a total of 11 persons on 14 different workstations inputted 16591 entries (files for 2370. The merge process was tested on 2 operating systems - when copied together all files sort up as expected by patient, and for each patient in a chronological order, providing a digital cumulative patient record, which contains heterogeneous file formats.Conclusion: The file based approach for storing heterogeneous digital patient related information is an reliable system, which can handle open-source, proprietary, general and custom file formats and seems to be easily scalable. Further development of software for automatic checks of the integrity and searching and indexing of the files is expected to produce a more user-friendly environment

  1. The Effects of Viewing and Preferences for Online Cancer Information Among Patients' Loved Ones.

    Lauckner, Carolyn


    Emotional and psychological distress is common among loved ones of cancer patients, who sometimes report more severe mental health issues than the patients themselves. In addition, many loved ones feel as though their information needs are not being met, which can lead them to seek out additional information online. This survey research examined the experiences of cancer patients' loved ones in viewing online content about the disease and the emotional outcomes of such browsing sessions. Participants (N = 191) were recruited from cancer- and caregiver-related nonprofits and online discussion boards. Results indicated that patients' loved ones were active users of online cancer Web sites. They primarily viewed and expressed a desire for information-based, rather than support-based, content. Many individuals desired in-depth treatment information, and those who viewed it had significantly more hope. Interestingly, multiple regression analysis revealed that viewing user-generated content was associated only with negative emotions, illustrating the potential dangers of social media spaces. Overall, this study shows the need for supporting patients' loved ones during their almost inevitable viewings of online cancer information. More research is needed in order to determine the best methods of mitigating potential negative effects of cancer Web sites and developing a useful online resource for this population. PMID:26636409

  2. Information on the Internet for asplenic patients: a systematic review

    Downing, Mark A.; Omar, Ahmed H.; Sabri, Elham; McCarthy, Anne E.


    Background Asplenic patients in general have poor knowledge about their condition. Patients are increasingly turning to the Internet for their health care information, therefore this is a resource that many asplenic patients will use. The aim of our study was to determine the quality of information on the Internet for asplenic patients. Methods We identified websites by entering “splenectomy OR spleen removal” into 3 Internet search engines on July 28, 2008. The top 50 English-language websites from each search engine were included in our analysis. We evaluated the websites with our own 21-point content scale as well as 4 commonly used quality-assessment tools. All websites were analyzed independently by 2 reviewers. Correlations were made between the quality assessment instruments, content, readability and target audience. Results We included 89 websites in the study. The mean content score percentage for all websites was 49% (95% confidence interval 44%–54%). The long-term risk of infection was mentioned in 84% of websites, and the need for vaccination was mentioned in 79%. The mean quality assessment tool score was 61%, and the mean reading grade level was 11. Conclusion Whereas websites on average did not cover most of the information that asplenic patients should receive, the long-term risk of serious infection and the need for vaccination was consistently mentioned. Websites were inconsistent with respect to adhering to standards advocated by the quality assessment instruments we used, and the mean reading grade level was far above what is recommended for patient literature.

  3. A Clinician-Guided Nonsurgical Cosmetic Patient Information Module: Preliminary Findings.

    Warren, Hermine Jan


    In 2011, nearly 13 million nonsurgical cosmetic procedures were performed, representing a 6% increase from the previous year. Patients often present with unrealistic treatment expectations based on beauty industry standards and misinformation. In addition, because of the lack of competency standardization in this area, providers frequently deliver inconsistent educational information to their patients. The initial goal of the project was to evaluate the clinician-guided module, a 13-slide PowerPoint presentation that was disseminated to key stakeholders for preliminary review. A convenience sample of 10 women, aged 30-64 years, was recruited. Following exposure to the module, each participant was asked to fill out an evaluation composed of both closed- and open-ended responses, noting her experience with this type of educational tool. Quantitative data were analyzed using comparison of means, whereas qualitative data were examined for the emergence of themes. Initial findings suggested that patients and health care providers found the clinician-guided module informative and visually appealing and that they would recommend this module to peers and colleagues. Potential social change from this project may surface through increased patient knowledge and empowerment, awareness, safety, and satisfaction. The final project will compare the clinician-guided patient information module to standard patient information evaluating treatment expectations of dermal fillers. The ultimate impact of a clinician-guided information module may improve standardization in this arena and thus be of particular interest to members of the nonsurgical cosmetic community.

  7. Information-Technology Based Physics Education

    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. An efficient steganography method for hiding patient confidential information.

    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). PMID:25569937

    An information retrieval system for the INIS data base is described. It allows for batch processing on an IBM/360 or /370 computer operated under OS or VS. The program package consists basically of IBM's IRMS system which was converted from DOS to OS and adapted for INIS requirements. Sections 1-9 present the system from the user's point of view, deliberately omitting all the programming details. Program descriptions with data set definitions and file formats are given in sections 10-12. (author)

  13. Lay perceptions of evidence-based information – a qualitative evaluation of a website for back pain sufferers

    Nilsen Elin S; Glenton Claire; Carlsen Benedicte


    Abstract Background In an evidence-informed patient choice the patient has access to research-based information about the effectiveness of health care options and is encouraged to use this information in treatment decisions. This concept has seen growing popularity in recent years. However, we still know relatively little about users' attitudes to the use of research-based information, possibly because people have been unexposed to this type of information. After developing the BackInfo websi...

  14. Flexible patient information search and retrieval framework: pilot implementation

    Erdal, Selnur; Catalyurek, Umit V.; Saltz, Joel; Kamal, Jyoti; Gurcan, Metin N.


    Medical centers collect and store significant amount of valuable data pertaining to patients' visit in the form of medical free-text. In addition, standardized diagnosis codes (International Classification of Diseases, Ninth Revision, Clinical Modification: ICD9-CM) related to those dictated reports are usually available. In this work, we have created a framework where image searches could be initiated through a combination of free-text reports as well as ICD9 codes. This framework enables more comprehensive search on existing large sets of patient data in a systematic way. The free text search is enriched by computer-aided inclusion of additional search terms enhanced by a thesaurus. This combination of enriched search allows users to access to a larger set of relevant results from a patient-centric PACS in a simpler way. Therefore, such framework is of particular use in tasks such as gathering images for desired patient populations, building disease models, and so on. As the motivating application of our framework, we implemented a search engine. This search engine processed two years of patient data from the OSU Medical Center's Information Warehouse and identified lung nodule location information using a combination of UMLS Meta-Thesaurus enhanced text report searches along with ICD9 code searches on patients that have been discharged. Five different queries with various ICD9 codes involving lung cancer were carried out on 172552 cases. Each search was completed under a minute on average per ICD9 code and the inclusion of UMLS thesaurus increased the number of relevant cases by 45% on average.

    Yumura, Yasushi; Hattori, Yusuke; Gobara, Ayako; Takamoto, Daiji; Yasuda, Kengo; Nakamura, Masafumi; Noguchi, Kazumi; Asahina, Kan; Kamijo, Takeo


    It is very important to share patient information because home patient care involves several different specialties of care. We introduced Cybozulive ® , a cloud-based free groupware, for 14 terminal-stage patients with urological cancer to share information among doctors and co-medical staff. This system enables access to patient information regardless of time and place. Of the 14 patients (mean age 74.4 years), 11 died of cancer. The average period in which Cybozulive® was used for the patients was 210 days. The average number of entries to the electronic bulletin board in this period was 88.4. We were able to obtain more information about the patients from the website. There was no difference in the average number of times that the patient consulted the out patient clinic before and after the introduction of Cybozulive® (before 7.0 ; after 6.3). After introduction of this system, eleven patients were hospitalized in our department 21 times. Eighteen of these 21 times, since we had acquired patient information from the website beforehand, there was a quick response for management of the emergency admission. This system could be used to construct a network for home care and may be helpful for sharing patient information in homecare. PMID:25293794

  16. Factors Associated with Strain in Informal Caregivers of Stroke Patients

    Jen-Wen Hung


    Full Text Available Background: Stroke is one of the most prevalent causes of adult disability and handicap. Informal caregivers play an important role in poststroke care. However, informal caregivers may experience strain, which threatens the recovery of stroke subjects. This study aimed to describe changes in strain experienced by informal caregivers from 3 to 6 months after the stroke, and identify the predicting factors.Methods: We recruited pairs of inpatients with ischemic stroke and informal caregivers from a tertiary referral hospital and interviewed them at 3 and 6 months after the stroke. Caregiver strain was evaluated using the Caregiver Strain Index (CSI, with a CSI Ÿ 7 indicating considerable caregiver strain. Various factors associated with caregiver strain were analyzed using generalized estimating equations.Results: Eighty-nine stroke patients and caregivers completed the study. Considerable strain was reported in 46% and 43% of the caregivers at the 3rd and 6th month, respectively. Patient factors such as severe disabilities (Barthel Index ŷ 60, poor cognition (Mini-Mental State Examination ŷ 23, depression (Beck Depression Inventory [BDI] Ÿ 10, and recurrent stroke were predictors for caregiver strain. Caregiver factors, such as changed employment status, help from formal caregivers, and depression (BDI Ÿ 10 were also associated with considerable caregiver strain.Conclusions: Nearly 50% of caregivers experienced considerable strain. Interventions aimed at reducing the caregivers’ strain should focus on enhancing the functional and emotional status of stroke subjects, prevention of recurrent stroke, and efficient management of depression symptoms in caregivers.

  17. Preface: Internet-Based Management Information Systems


    @@ 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.

  18. Genome Informed Trait-Based Models

    Karaoz, U.; Cheng, Y.; Bouskill, N.; Tang, J.; Beller, H. R.; Brodie, E.; Riley, W. J.


    Trait-based approaches are powerful tools for representing microbial communities across both spatial and temporal scales within ecosystem models. Trait-based models (TBMs) represent the diversity of microbial taxa as stochastic assemblages with a distribution of traits constrained by trade-offs between these traits. Such representation with its built-in stochasticity allows the elucidation of the interactions between the microbes and their environment by reducing the complexity of microbial community diversity into a limited number of functional ';guilds' and letting them emerge across spatio-temporal scales. From the biogeochemical/ecosystem modeling perspective, the emergent properties of the microbial community could be directly translated into predictions of biogeochemical reaction rates and microbial biomass. The accuracy of TBMs depends on the identification of key traits of the microbial community members and on the parameterization of these traits. Current approaches to inform TBM parameterization are empirical (i.e., based on literature surveys). Advances in omic technologies (such as genomics, metagenomics, metatranscriptomics, and metaproteomics) pave the way to better-initialize models that can be constrained in a generic or site-specific fashion. Here we describe the coupling of metagenomic data to the development of a TBM representing the dynamics of metabolic guilds from an organic carbon stimulated groundwater microbial community. Illumina paired-end metagenomic data were collected from the community as it transitioned successively through electron-accepting conditions (nitrate-, sulfate-, and Fe(III)-reducing), and used to inform estimates of growth rates and the distribution of metabolic pathways (i.e., aerobic and anaerobic oxidation, fermentation) across a spatially resolved TBM. We use this model to evaluate the emergence of different metabolisms and predict rates of biogeochemical processes over time. We compare our results to observational

  1. Cloud based emergency health care information service in India.

    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

  3. Partial order similarity based on mutual information

    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...

  5. Iterative evaluation of a web-based health information resource.

    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. PMID:23577665

  6. MobiDis: Toward a Patient Centric Healthcare Information System.

    Ricci, Fabrizio L; Serbanati, Luca D


    The paper presents some results of the MobiDis project. MobiDis is an information system that includes healthcare consumers and providers in a unique, virtual organisation aimed at promoting a patient centric paradigm in healthcare. It allows logons from desktop or laptop computers, as well as wireless PDAs or tablet PCs connected to Internet. In MobiDis the clinical data of each consumer are stored in the consumer's virtual healthcare record (VHR), a highly structured entity that exists on the network and is simultaneously updated with information from multiple locations. The MobiDis architecture creates an environment for VHRs by providing them with a large variety of services. In order to prove that our proposed architectural solution meets the project goals a prototype was developed. The paper describes the MobiDis architecture and the VHR services, and briefly presents the prototype. PMID:16160316

  7. Concept Tree Based Information Retrieval Model

    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

    LIU De-zhi; RAZDAN Anshuman; SIMON Arleyn; BAE Myungsoo


    An information model is defined to support sharing scientific information on Web for archaeological pottery. Apart from non-shape information, such as age, material, etc., the model also consists of shape information and shape feature information. Shape information is collected by Lasers Scanner and geometric modelling techniques. Feature information is generated from shape information via feature extracting techniques. The model is used in an integrated storage, archival, and sketch-based query and retrieval system for 3D objects, native American ceramic vessels. A novel aspect of the information model is that it is totally implemented with XML, and is designed for Web-based visual query and storage application.

  9. Information Status of the Patients about Radiological Examinations and Encountered Ethical and Medical Issues

    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.

  10. How Do Cancer Patients Navigate the Public Information Environment? Understanding Patterns and Motivations for Movement Among Information Sources

    Romantan, Anca; Kelly, Bridget J.; Stevens, Robin S.; Gray, Stacy W.; Hull, Shawnika J.; Ramirez, A. Susana; Hornik, Robert C.


    Little is known about how patients move among information sources to fulfill unmet needs. We interviewed 43 breast, prostate, and colorectal cancer patients. Using a grounded theory approach, we identified patterns and motivations for movement among information sources. Overall, patients reported using one source (e.g., newspaper) followed by the use of another source (e.g., Internet), and five key motivations for such cross-source movement emerged. Patients’ social networks often played a central role in this movement. Understanding how patients navigate an increasingly complex information environment may help clinicians and educators to guide patients to appropriate, high-quality sources. PMID:20204573

    Kelly Lu Ting Ee


    Full Text Available Abstract: Surgeries are seen as stressors that triggerpreoperative anxiety. Preparing the patients for surgerythrough preoperative teaching becomes crucial to allayanxiety level. In a cross sectional descriptive studyconducted on eighty patients (age: 18–65 yr who hadundergone open abdominal surgery, 78.8% (n=63 statedthat they experienced anxiety prior to surgery. Amongthese anxious respondents, 47.5% (n=38 experiencedhigh state anxiety. Three of the top information thatpatients perceived as important to allay anxiety towardsmajor surgery were: details of surgery, details of nursingcare to surgery and information on anaesthesia. Nursesworking in the surgical wards need to proactively addresspatients’ psychological concerns towards surgery andprovide preoperative information based on patients’needs to allay anxiety.

  15. The effects of preparatory sensory information on ICU patients.

    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.

    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.

  20. Older cancer patients' information and support needs surrounding treatment: An evaluation through the eyes of patients, relatives and professionals

    van Weert Julia CM


    Full Text Available Abstract Background Providing cancer patients with adequate treatment information is important for patients' health, well-being and satisfaction. Nurses play an important role in patient education. So far, few studies focused on the specific information needs of older cancer patients surrounding chemotherapy treatment. Given the growing incidence of cancer among older individuals, insight in these needs is crucial. This article describes the views of older cancer patients, their relatives and professionals on older patients' specific communication needs regarding chemotherapy treatment. Methods A qualitative design was used. Five focus group interviews were held with older cancer patients and their partners (two groups and professionals with a background in nursing, oncology, gerontology and/or patient-provider communication (three groups. In addition, face to face in-depth interviews were conducted with older cancer patients. A total number of 38 patients and relatives participated, with a mean age of 67.6 years. The focus groups and interviews were audio-recorded for subsequent transcription and analysis. Results Older people have more difficulties processing and remembering information than younger ones. A trustful environment appears to be a prerequisite for reflection of older patients on the information provided and individualized information is essential to enhance memory of information. However, the results show that both patients and professionals experienced insufficient exploration of the patients' personal situation and individual information needs. Patients also strengthened the importance of sensitive communication, e.g. showing empathy en emotional support, throughout the continuum of cancer care. Moreover, potential areas of improvement were identified, including engaging the patients' relatives and encouraging patients and relatives to ask questions. Conclusion Patient education should be more tailored to older cancer patients

    The proliferation of information sources available on the Wide World Web has resulted in a need for database selection tools to locate the potential useful information sources with respect to the user's information need. Current database selection tools always treat each database independently, ignoring the implicit, useful associations between distributed databases. To overcome this shortcoming, in this paper, we introduce a data-mining approach to assist the process of database selection by...

  8. Comparing the security risks of paper-based and computerized patient record systems

    Collmann, Jeff R.; Meissner, Marion C.; Tohme, Walid G.; Winchester, James F.; Mun, Seong K.


    How should hospital administrators compare the security risks of paper-based and computerized patient record systems. There is a general tendency to assume that because computer networks potentially provide broad access to hospital archives, computerized patient records are less secure than paper records and increase the risk of breaches of patient confidentiality. This assumption is ill-founded on two grounds. Reasons exist to say that the computerized patient record provides better access to patient information while enhancing overall information system security. A range of options with different trade-offs between access and security exist in both paper-based and computerized records management systems. The relative accessibility and security of any particular patient record management system depends, therefore, on administrative choice, not simply on the intrinsic features of paper or computerized information management systems.

  10. Completeness of Information Sources Used to Prepare Best Possible Medication Histories for Pediatric Patients

    Dersch-Mills, Deonne; Hugel, Kimberly; Nystrom, Martha


    Background: Medication reconciliation can reduce medication errors and mortality. With limited availability of clinical pharmacists, it is important to determine the resources that will yield the most complete information about a patient’s medication history. Objective: To identify the most time-efficient sources of information about medication history for use by clinicians in a pediatric care setting. Methods: In July and August 2009, newly admitted pediatric patients (under 18 years of age) were identified, and a best possible medication history (BPMH) was compiled from the admission history in each patient’s chart, a provincial prescription database, a community pharmacy record, and an “informed interview”. Each individual source of information was compared with the BPMH and given a completeness score based on 3 pieces of information about each medication (name, dose, and frequency). Results: Data were collected for 99 pediatric patients. Of these, 76 (77%) were taking at least one medication, and 49 (50%) were taking at least one prescription medication. Among patients who were taking at least one medication, the informed interview, based on background information from other sources, resulted in the most comprehensive medication history, with a median completeness score of 100% (interquartile range [IQR] 90% to 100%). The admission history had a median completeness score of 33% (IQR 4% to 56%), with documentation of dose and frequency lacking most frequently. Information from community pharmacies had a median completeness score of 67% (IQR 42% to 87%), but this source was available for only 24 of the 99 patients. The prescription database was the least complete source, with a median completeness score of 0% (IQR 0% to 37%). Conclusion: An informed interview by a trained professional resulted in the most complete medication history. Admission histories represented the next most complete source. The data from this study indicated a need for education on

  13. Informing Patients About Placebo Effects: Using Evidence, Theory, and Qualitative Methods to Develop a New Website

    Greville-Harris, Maddy; Bostock, Jennifer; Din, Amy; Graham, Cynthia A; Lewith, George; Liossi, Christina; O’Riordan, Tim; White, Peter; Yardley, Lucy


    Background According to established ethical principles and guidelines, patients in clinical trials should be fully informed about the interventions they might receive. However, information about placebo-controlled clinical trials typically focuses on the new intervention being tested and provides limited and at times misleading information about placebos. Objective We aimed to create an informative, scientifically accurate, and engaging website that could be used to improve understanding of placebo effects among patients who might be considering taking part in a placebo-controlled clinical trial. Methods Our approach drew on evidence-, theory-, and person-based intervention development. We used existing evidence and theory about placebo effects to develop content that was scientifically accurate. We used existing evidence and theory of health behavior to ensure our content would be communicated persuasively, to an audience who might currently be ignorant or misinformed about placebo effects. A qualitative ‘think aloud’ study was conducted in which 10 participants viewed prototypes of the website and spoke their thoughts out loud in the presence of a researcher. Results The website provides information about 10 key topics and uses text, evidence summaries, quizzes, audio clips of patients’ stories, and a short film to convey key messages. Comments from participants in the think aloud study highlighted occasional misunderstandings and off-putting/confusing features. These were addressed by modifying elements of content, style, and navigation to improve participants’ experiences of using the website. Conclusions We have developed an evidence-based website that incorporates theory-based techniques to inform members of the public about placebos and placebo effects. Qualitative research ensured our website was engaging and convincing for our target audience who might not perceive a need to learn about placebo effects. Before using the website in clinical trials

    Full Text Available Hedi Klila,1 Anne Chatton,2 Ariane Zermatten,2 Riaz Khan,2 Martin Preisig,1,3 Yasser Khazaal2,4 1Department of Psychiatry, Lausanne University Hospital, Lausanne, Switzerland; 2Department of Mental Health and Psychiatry, Geneva University Hospitals, Geneva, Switzerland; 3Lausanne University, Lausanne, Switzerland; 4Geneva University, Geneva, Switzerland Background: The Internet is increasingly used as a source of information for mental health issues. 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

  19. Photodiode based dosemeter for patient dose monitoring

    This work describes the performance of a dosemeter, based on a photodiode device, compared to an ionization chamber for on-line dose monitoring applied to the patient during radiotherapy procedures. The dosemeter is constituted by two photodiodes, connected without polarisation to a digital current integrator. The dosemeter was tested in a water phantom and 60Co gamma ray. The depth dose distribution and the variation response with depth of the dosemeter were obtained. The results were compared to those obtained with a secondary standard, take as reference dosemeter. The response of this dosemeter had a deviation of 0,7 % from the ion chamber performance in water phantom measurement. The response variation with depth was less than 1 %. This is better than 8 % of diodes, determined by other authors. The developed device can substitute ion chambers in some routine absorbed dose to water measurements, with advantage of low cost and robust form. It has better performance than diodes, for given dose for patient. (author)

  20. Mutual information-based feature selection for radiomics

    Oubel, Estanislao; Beaumont, Hubert; Iannessi, Antoine


    Background The extraction and analysis of image features (radiomics) is a promising field in the precision medicine era, with applications to prognosis, prediction, and response to treatment quantification. In this work, we present a mutual information - based method for quantifying reproducibility of features, a necessary step for qualification before their inclusion in big data systems. Materials and Methods Ten patients with Non-Small Cell Lung Cancer (NSCLC) lesions were followed over time (7 time points in average) with Computed Tomography (CT). Five observers segmented lesions by using a semi-automatic method and 27 features describing shape and intensity distribution were extracted. Inter-observer reproducibility was assessed by computing the multi-information (MI) of feature changes over time, and the variability of global extrema. Results The highest MI values were obtained for volume-based features (VBF). The lesion mass (M), surface to volume ratio (SVR) and volume (V) presented statistically significant higher values of MI than the rest of features. Within the same VBF group, SVR showed also the lowest variability of extrema. The correlation coefficient (CC) of feature values was unable to make a difference between features. Conclusions MI allowed to discriminate three features (M, SVR, and V) from the rest in a statistically significant manner. This result is consistent with the order obtained when sorting features by increasing values of extrema variability. MI is a promising alternative for selecting features to be considered as surrogate biomarkers in a precision medicine context.

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

    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

  2. Information on antidepressants for psychiatric inpatients: the divide between patient needs and professional practice

    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

  7. The role of the medical school-based consumer health information service.

    La Rocco, A


    Historically, medical information has been provided to patients at the physician's discretion. Although this method never has been wholly satisfactory, the trend toward bureaucratic organization of medical care, characterized by impersonal patient encounters and prompted by increased emphasis on cost controls, has restricted patient information even further. Yet, at the same time, the upsurge in consumer power has created patient demand for more health information. Consumers feel they have a right to expect help in obtaining information so they can make informed decisions with respect to their medical care. This paper focuses on the medical school-based consumer health service in this context. In particular, it calls attention to the medical school library as the foundation for expanded health information resources, pointing to the tools of information retrieval, as well as the substantive information contained in the medical, nursing, and allied health literature. In this setting, the consumer health librarian is called upon to act as a mediator in providing quality-filtered information to the patron, while at the same time remaining within the confines of professional expertise as a librarian. Important sources of health information are highlighted, particularly online databases, drug indexes, therapeutic texts, and physician specialist directories. PMID:8136760

  8. Cultural competency, autonomy, and spiritual conflicts related to Reiki/CAM therapies: Should patients be informed?

    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. PMID:24899738

  9. Medical Communication-related Informational Need and Resource Preferences Among Family Caregivers for Head and Neck Cancer Patients.

    Longacre, Margaret L; Galloway, Thomas J; Parvanta, Claudia F; Fang, Carolyn Y


    Despite advances in treatment, head and neck cancer (HNC) patients often experience considerable functional impairment during and following treatment. As a result, family caregivers are essential in a patient's recovery; however, few caregivers are well-prepared to handle the extensive caregiving needs of this patient population. To date, little is known about HNC caregivers' informational needs in this role. Thus, we surveyed a sample of HNC caregivers about their informational needs including those related to interacting in the medical context as a caregiver and meeting patient needs. We also asked these caregivers their preferences for obtaining caregiving information. We conducted a cross-sectional study of 59 family caregivers for HNC patients who had completed radiation therapy at a comprehensive cancer center. The majority of caregivers (74.6%) reported having high informational need at diagnosis related to interacting as a caregiver. Although the need for such information decreased over time, over half still had a high need for information at treatment end. Importantly, caregivers who desired information about reducing patient pain and distress also reported having greater informational needs on issues related to interacting in the medical context. Further, the caregivers most often preferred to receive information from health-care professionals as a first source. However, preferring an informal (e.g., Internet) resource at first was significantly associated with needing information on how to talk to a doctor or nurse. The development of evidence-based resources and tools for HNC caregivers as well as clinicians may help caregivers more effectively manage patient symptoms and warrants further attention. Further, Internet resources may represent an effective resource for providing caregivers with strategies toward enhancing communication with healthcare professionals. PMID:25893922

    Full Text Available Metaphoric language has grown in popularity over the last years. Once simple figure of speech, metaphors were transformed into a respectable approach for organizational analysis. The brain metaphor constitutes an attractive system of ideas for studying organizational phenomena. In this paper, it is used the brain metaphor as a point of departure in developing another informational metaphor: the network metaphor. It is suggested that the latter might provide a better perspective for studying contemporary organizations in this age of information and telecommunications.

  15. Use of information sources by cancer patients: results of a systematic review of the research literature

    Kalyani Ankem


    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.

  17. Zigbee Based Wearable Remote Healthcare Monitoring System for Elderly Patients

    Khalifa AlSharqi


    Full Text Available Remote health care monitoring system (RHCMS has drawn considerable attentions for the last decade. As the aging population are increasing and at the same time the health care cost is skyrocketing there has been a need to monitor a patient from a remote location. Moreover, many people of the World are out of the reach of existing healthcare systems. To solve these problems many research and commercial versions of RHCMS have been proposed and implemented till now. In these systems the performance was the main issue in order to accurately measure, record, and analyze patients’ data. With the ascent of wireless network RHCMS can be widely deployed to monitor the health condition of a patient inside and outside of the hospitals. In this work we present a ZigBee based wireless healthcare monitoring system that can provide real time online information about the health condition of a patient. The proposed system is able to send alarming messages to the healthcare professional about the patient’s critical condition. In addition the proposed system can send reports to a patient monitoring system, which can be used by the healthcare professionals to make necessary medical advices from anywhere of the World at any time.

  18. Pattern recognition of quantum information based on pattern-distance

    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.

  19. Information criterion based fast PCA adaptive algorithm

    Li Jiawen; Li Congxin


    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.

    Wire-based tracking devices are an affordable alternative to costly tracking devices. They consist of a fixed base and a platform, attached to the moving object, connected by six wires whose tension is maintained along the tracked trajectory. One important shortcoming of this kind of devices is that they are forced to operate in reduced workspaces so as to avoid singular configurations. Singularities can be eliminated by adding more wires but this causes more wire interferences, and a higher ...

Although information technology (IT) has done much to advance medicine, we are not even close to realizing its full potential. Indeed, issues related to mismanaging health information often undermine relationship-centered care. Information technology must be implemented in ways that preserve and uplift relationships in care, while accommodating major deficiencies in managing information and m...

  5. Brain Tumor Detection Based on Bilateral Symmetry Information

    Narkhede Sachin,


    Full Text Available Advances in computing technology have allowed researchers across many fields of endeavor to collect and maintain vast amounts of observational statistical data such as clinical data, biological patient data, data regarding access of web sites , financial data, and the like. Brain Magnetic Resonance Imaging (MRI segmentation is a complex problem in the field of medical imaging despite various presented methods. MR image of human brain can be divided into several sub-regions especially soft tissues such as gray matter, white matter and cerebrospinal fluid. Although edge information is the main clue in image segmentation, it can’t get a better result in analysis the content of images without combining other information. The segmentation of brain tissue in the magnetic resonance imaging (MRI is very important for detecting the existence and outlines of tumors. In this thesis , an algorithm about segmentation based on the symmetry character of brain MRI image is presented. Our goal is to detect the position and boundary of tumors automatically. Experiments were conducted on real pictures, and the results show that the algorithm is flexible and convenient.

  8. Information Technology & Goals of Standards-Based Instruction

    Douglas A. Archbald


    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 leve...
