    In the current climate of increasing awareness, patients are demanding more knowledge about forthcoming operations. The patient information accounts for a considerable part of the physician's daily clinical routine. Unfortunately, only a small percentage of the information is understood by the patient after solely verbal elucidation. To optimise information delivery, different auxiliary materials are used. In a prospective study, 52 consecutive stationary patients, scheduled for an elective lumbar disc operation were asked to use a web-based audiovisual patient information system. A combination of pictures, text, tone and video about the planned surgical intervention is installed on a tablet personal computer presented the day before surgery. All patients were asked to complete a questionnaire. Eighty-four percent of all participants found that the audiovisual patient information system lead to a better understanding of the forthcoming operation. Eighty-two percent found that the information system was a very helpful preparation before the pre-surgical interview with the surgeon. Ninety percent of all participants considered it meaningful to provide this kind of preoperative education also to patients planned to undergo other surgical interventions. Eighty-four percent were altogether "very content" with the audiovisual patient information system and 86% would recommend the system to others. This new approach of patient information had a positive impact on patient education as is evident from high satisfaction scores. Because patient satisfaction with the informed consent process and understanding of the presented information improved substantially, the audiovisual patient information system clearly benefits both surgeons and patients.

    Patient information leaflets are universally-accepted resources to educate the patients/users about their medications, disease and lifestyle modification. The objective of the study was to prepare, validate and perform user-testing of pictogram-based patient information leaflets (P-PILs) among hemodialysis (HD) patients. The P-PILs are prepared by referring to the primary, secondary and tertiary resources. The content and pictograms of the leaflet have been validated by an expert committee consisting of three nephrologists and two academic pharmacists. The Baker Able Leaflet Design has been applied to develop the layout and design of the P-PILs. Quasi-experimental pre- and post-test design without control group was conducted on 81 HD patients for user-testing of P-PILs. The mean Baker Able Leaflet Design assessment score for English version of the leaflet was 28, and 26 for Kannada version. The overall user-testing knowledge assessment mean scores were observed to have significantly improved from 44.25 to 69.62 with p value <0.001. The overall user opinion of content and legibility of the leaflets was good. Pictogram-based patient information leaflets can be considered an effective educational tool for HD patients.

    The task of informing the cancer patient is considered an arduous one as it typically involves breaking bad news to the patient. It appears that the adoption of an empathic approach is vital within a therapeutic relationship. This applies to every character or personality type, perhaps more so to the arrogant patient with a feeling of superiority. The question "Is it possible to determine who should be told what, when and how" basically implies the adoption of an empathic approach and the tailoring of information to each cancer patient. The use of character traits contributes to managing the physically ill patient in the best possible way. Therefore, follows the question: in what way does a character or personality type affect cancer patient informing? The aim of this article was to describe the arrogant (narcissistic) character or type of personality in an analytic way so that any therapist can make a diagnosis and tailor the information strategy to the patient's needs. As method of research was used the qualitative method research through groups with doctors and nurses, while research within groups lasted for 5 years. The degree of informing the arrogant personality in the range "minimal - small - medium - large - very large" is: The degree of denial varies between "large" and "very large" while the degree of informing varies between "medium" and "small". Informing the family: The patient objects to a common approach with the family as he is concerned about inflicting a blow to his image.

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

    Communicating bad news is often part of a doctor's task. By bad news we mean information which is received as unpleasant by the patient who feels that it can have an unwanted effect in his life. It appears that the way each patient assesses bad news is associated with his personality type, his individual character traits and the adoption of an empathic approach is vital within a therapeutic relationship. The aim of this article was to describe the uninvolved-aloof character or type of personality thoroughly so that any therapist can make a diagnosis and tailor the information strategy to the patient's needs. As method of research was used the qualitative method through groups with doctors and nurses, while research within groups lasted for 5 years. Assessing the denial mechanism may present the hardest task since the patient does not give any hint to the doctor as to how he feels. The degree of informing should be not as much as for the controlling-orderly person but more than the dependent person's, about "average" to "small". Informing Family: He accepts the family's involvement. Relatives need to be alerted about the patient's fragility.

    Imparting the bad news has become a hard task for the doctor, and is usually perceived as unpleasant by the patient to whom the bad news is revealed. It is vital that the physician's approach be tailored to the cancer patient's personality. Gathering by the informing process protocols already suggested the hardest step for the doctors to take is empathic understanding which, presupposes tailoring to the individual's needs. The aim of this article was to describe the self-sacrificing type of personality thoroughly, so that any physician can make a diagnosis and tailor the information strategy to their needs. As method of research was used the qualitative method through groups with doctors and nurses, while research within groups lasted for 5 years. Assessing the denial mechanism is hard for a person that regards disease as punishment and propitiation. The physician must mobilize his countertransference, the sense he gets from the discussions with the patient and their overall communication. If he finds that the patient has self-control, then the approach of imparting the news resembles that of the controlling-orderly personality. If he ascertains that the patient has a lasting embarrassment, he should be more careful and impart the news gradually, his approach resembling that of the dependent person.

    This project aimed to improve patients' knowledge on the importance of hand hygiene. It involved providing patients with a patient and family education on the importance of hand hygiene using a patient information leaflet that introduces the rationale of hand hygiene, possible consequences of poor hand hygiene, and the seven steps of hand hygiene. This projected used a preimplementation and postimplementation audit strategy using the Joanna Briggs Institute Practical Application of Clinical Evidence System and Getting Research Into Practice programs. The implementation occurred in three phases over a period of 6 months from January 2014 to June 2014. The audits took place in two orthopaedic wards in a large acute care setting tertiary hospital in Singapore and involved a sample size of 54 patients. It involved going through the medical records of the cases, assessment of patient knowledge based on the audit criteria, and checking if the patients received the patient information leaflet on hand hygiene. The postimplementation audit found significant improvements in all three audit criteria. The percentage of patients who demonstrated knowledge in the importance of hand hygiene saw an improvement of 48.1%. There was an improvement of 44.5% in nurses' compliance to the documentation of patient education being carried out. The percentage of patients who received a patient information leaflet on hand hygiene saw an increase of 36.1%. This project demonstrated that a preimplementation and postimplementation audit is a viable method to implement change and translate evidence into practice. Through this project, patients gained an understanding on the importance of hand hygiene and could take better ownership of their well being. This may potentially improve hospitalization experience and benefit health outcomes. The positive results of this project are contributed by the enthusiastic involvement of all the stakeholders, from patients and their caregivers to the bedside

    The internet is an easy and always accessible source of information for cancer patients. The aim of our study was to evaluate the information provided on German websites. We developed an instrument based on criteria for patient information from the German Network for Evidence-based Medicine, the Agency for Quality in Medicine, HONcode, DISCERN, and the afgis. We simulated a patient's search and derived the websites for evaluation. We analyzed the visibility of each website and evaluated the websites using the developed instrument. We analyzed 77 websites. The highest visibility index was shown by 4 profit websites. Websites from professional societies and self-help groups have low rankings. Concerning quality, websites from non-profit providers and self-help groups are on top. Websites with a profit interest have the lowest average score. A discrepancy exists between the visibility and the quality of the analyzed websites. With the internet becoming an important source of information on cancer treatments for patients, this may lead to false information and wrong decisions. We provide a list of suggestions as to how this risk may be reduced by complementary information from the physician and from trustworthy websites. © 2015 S. Karger GmbH, Freiburg.

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

    A user friendly interface can enhance the efficiency of data entry, which is crucial for building a complete database. In this study, two user interfaces (traditional pull-down menu vs. check boxes) are proposed and evaluated based on medical records with fever medication orders by measuring the time for data entry, steps for each data entry record, and the complete rate of each medical record. The result revealed that the time for data entry is reduced from 22.8 sec/record to 3.2 sec/record. The data entry procedures also have reduced from 9 steps in the traditional one to 3 steps in the new one. In addition, the completeness of medical records is increased from 20.2% to 98%. All these results indicate that the new user interface provides a more user friendly and efficient approach for data entry than the traditional interface.

    Evidence regarding the benefits, opportunities, and risks associated with providing health care to patients experiencing gender-based violence (GBV) and, moreover, their satisfaction with health care services is sparse. Using a patient- and trauma-informed relationship-based framework, survivors of GBV who were referred for follow-up care were asked to participate in a quality improvement (QI) initiative in an effort to understand their perspectives of receiving healthcare services. Patients were asked to answer three open-ended questions in regard to their healthcare experience. Individuals who were eligible for evidence collection after sexual assault (sexually assaulted should have evidence collected. More extensive research and program evaluation including outcomes research are warranted.

    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.

    Full Text Available Several studies have reported gene expression signatures that predict recurrence risk in stage II and III colorectal cancer (CRC patients with minimal gene membership overlap and undefined biological relevance. The goal of this study was to investigate biological themes underlying these signatures, to infer genes of potential mechanistic importance to the CRC recurrence phenotype and to test whether accurate prognostic models can be developed using mechanistically important genes.We investigated eight published CRC gene expression signatures and found no functional convergence in Gene Ontology enrichment analysis. Using a random walk-based approach, we integrated these signatures and publicly available somatic mutation data on a protein-protein interaction network and inferred 487 genes that were plausible candidate molecular underpinnings for the CRC recurrence phenotype. We named the list of 487 genes a NEM signature because it integrated information from Network, Expression, and Mutation. The signature showed significant enrichment in four biological processes closely related to cancer pathophysiology and provided good coverage of known oncogenes, tumor suppressors, and CRC-related signaling pathways. A NEM signature-based Survival Support Vector Machine prognostic model was trained using a microarray gene expression dataset and tested on an independent dataset. The model-based scores showed a 75.7% concordance with the real survival data and separated patients into two groups with significantly different relapse-free survival (p = 0.002. Similar results were obtained with reversed training and testing datasets (p = 0.007. Furthermore, adjuvant chemotherapy was significantly associated with prolonged survival of the high-risk patients (p = 0.006, but not beneficial to the low-risk patients (p = 0.491.The NEM signature not only reflects CRC biology but also informs patient prognosis and treatment response. Thus, the network-based

    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. © 2013 National Association for Healthcare Quality.

    Smartphones represent a promising technology for patient-centered healthcare. It is claimed that data mining techniques have improved mobile apps to address patients' needs at subgroup and individual levels. This study reviewed the current literature regarding data mining applications in patient-centered mobile-based information systems. We systematically searched PubMed, Scopus, and Web of Science for original studies reported from 2014 to 2016. After screening 226 records at the title/abstract level, the full texts of 92 relevant papers were retrieved and checked against inclusion criteria. Finally, 30 papers were included in this study and reviewed. Data mining techniques have been reported in development of mobile health apps for three main purposes: data analysis for follow-up and monitoring, early diagnosis and detection for screening purpose, classification/prediction of outcomes, and risk calculation (n = 27); data collection (n = 3); and provision of recommendations (n = 2). The most accurate and frequently applied data mining method was support vector machine; however, decision tree has shown superior performance to enhance mobile apps applied for patients' self-management. Embedded data-mining-based feature in mobile apps, such as case detection, prediction/classification, risk estimation, or collection of patient data, particularly during self-management, would save, apply, and analyze patient data during and after care. More intelligent methods, such as artificial neural networks, fuzzy logic, and genetic algorithms, and even the hybrid methods may result in more patients-centered recommendations, providing education, guidance, alerts, and awareness of personalized output.

    Consumer health information technology can improve patient engagement in their health care and assist in navigating the complexities of health care delivery. However, the consumer health information technology offerings of health systems are often driven by provider rather than patient perspectives and inadequately address patient needs, thus limiting their adoption by patients. Consideration given to patients as stakeholders in the development of such technologies may improve adoption, efficacy, and consumer health information technology resource allocation. The aims of this paper were to measure patient interest in different health system consumer health information technology apps and determine the influence of patient characteristics on consumer health information technology interest. Patients seen at the Cleveland Clinic Neurological Institute were electronically surveyed on their interest in using different consumer health information technology apps. A self-efficacy scale, Patient Health Questionnaire-9 depression screen, and EuroQol 5 dimensions health-related quality of life scale were also completed by patients. Logistic regression was used to determine the influence of patient characteristics on interest in consumer health information technology in the categories of self-management, education, and communication. The majority of 3852 patient respondents had an interest in all technology categories assessed in the survey. The highest interest was in apps that allow patients to ask questions of providers (3476/3852, 90.24%) and to schedule appointments (3211/3839, 83.64%). Patient interest in consumer health information technology was significantly associated with greater depression symptoms, worse quality of life, greater health self-efficacy, and smartphone ownership (Pinformation technology development and their perspectives should consistently guide development efforts. Health systems should consider focusing on consumer health information technologies

    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 A z 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 A z 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

    Patients with a neuroendocrine tumor (NET) frequently experience physical and psychosocial complaints. Novel strategies to provide information to optimize supportive care in these patients are of interest. The aim of this study was to examine whether the use of a web-based system consisting of self-screening of problems and care needs, patient education, and self-referral to professional health care is feasible in NET patients and to evaluate their opinion on this. Newly diagnosed NET patients were randomized between standard care (n = 10) or intervention with additional access to the web-based system (n = 10) during 12 weeks. Patients completed questionnaires regarding received information, distress, quality of life (QoL), and empowerment. The intervention group completed a semi-structured interview to assess patients' opinion on the web-based system. The participation rate was 77% (20/26 invited patients) with no dropouts. The use of the web-based system had a negative effect on patients' perception and satisfaction of received information (range Cohen's d -0.88 to 0.13). Positive effects were found for distress (Cohen's d 0.75), global QoL (subscale European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30, Cohen's d 0.46), resolving problems with social functioning and finding information (subscales EORTC QLQ-GINET 21, Cohen's d 0.69, respectively, 1.04), and feeling informed (subscale empowerment questionnaire, Cohen's d 0.51). The interview indicated that the web-based system was of additional value to standard care. Use of this web-based system is feasible. Contradictory effects on informing and supporting NET patients were found and should be subject of further research. NCT01849523.

    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.

    The importance of 'shared decision-making' is much emphasized in recent clinical guidelines regarding stroke management in atrial fibrillation (AF), more so following the inclusion of non-vitamin K oral anticoagulants (NOACs) among the treatment options. It is important that patients are navigated through balanced and unbiased information about the available treatment options, so as to understand the risk and benefits associated with the therapies, and to enable them to accordingly communicate their concerns and views with their clinicians prior to therapy selection. Given the increasing popularity of the Internet as a source of health information, the specific objectives of this study were to identify what aspects of thromboprophylaxis (antithrombotic treatment options) were most commonly described in these resources, both in terms of content, that is to report the information provided (quantitative) and the underlying themes underpinning this content, and in terms of how this information might guide patient preferences (qualitative). Resources for patients were identified via online search engines (Google, Yahoo, Ask, Bing), using the terms 'atrial fibrillation' and 'stroke' combined with patient/consumer information, patient/consumer resources and patient/consumer education. The researchers employed pragmatic (mix-method) approach to analyse the information presented within the resources using manual inductive coding, at two levels of analysis: manifest (reported surface theme or codes that are obvious and are countable) and latent (thematic, interpretative presentation of the content in the data set). In total, 33 resources were reviewed. The 'manifest-level' analysis found that warfarin was the most frequently mentioned thromboprophylactic option among the anticoagulants, being cited in all resources, followed by the NOACs - dabigatran (82·3% of resources), rivaroxaban (73·5%) and apixaban (67·6%). Only one-third of resources discussed the role of stroke

    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.

Several Web design guidelines for older Web users have been proposed; however, these guidelines are often not applied in website development. Furthermore, although we know that older individuals use the Internet to search for health information, we lack knowledge on how they use and evaluate Web-based health information. This study evaluates user experiences with existing Web-based health information tools among older (≥ 65 years) cancer patients and survivors and their partners. The aim was to gain insight into usability issues and the perceived usefulness of cancer-related Web-based health information tools. We conducted video-recorded think-aloud observations for 7 Web-based health information tools, specifically 3 websites providing cancer-related information, 3 Web-based question prompt lists (QPLs), and 1 values clarification tool, with colorectal cancer patients or survivors (n=15) and their partners (n=8) (median age: 73; interquartile range 70-79). Participants were asked to think aloud while performing search, evaluation, and application tasks using the Web-based health information tools. Overall, participants perceived Web-based health information tools as highly useful and indicated a willingness to use such tools. However, they experienced problems in terms of usability and perceived usefulness due to difficulties in using navigational elements, shortcomings in the layout, a lack of instructions on how to use the tools, difficulties with comprehensibility, and a large amount of variety in terms of the preferred amount of information. Although participants frequently commented that it was easy for them to find requested information, we observed that the large majority of the participants were not able to find it. Overall, older cancer patients appreciate and are able to use cancer information websites. However, this study shows the importance of maintaining awareness of age-related problems

    The Institute of Medicine (IOM) of the United States recommends that all cancer survivors be provided with a survivorship care plan (SCP), which includes a patient treatment summary and a follow-up care plan. However, SCPs have not been widely adopted in Japan. To provide basic data necessary for implementing SCPs in Japan, we aimed to investigate the forms of clinical and survivorship-related information that Japanese cancer survivors receive from their healthcare providers, and to examine whether written information increases their satisfaction. We performed a cross-sectional online survey of cancer survivors who underwent acute cancer treatment and had at least one follow-up with a physician in the past year. Cancer survivors provided the elements and forms (verbally and/or written) of information they received, as well as the degree of satisfaction with the information provided. Responses were obtained from 545 cancer survivors. Information elements such as surgical procedure (98.3%), surgical outcome (98.1%), and names of administered chemotherapy agents (97.8%) were commonly provided, whereas mental care resources and providers (29.7%), effects on marital relationship and sexual health (35.7%), and effects on fertility (43.4%) were less common. A large proportion of cancer survivors received verbal information only. For 18 of 20 elements, except for effects on fertility and duration of hormonal therapy, satisfaction was significantly higher when both forms of information were provided (P information can better meet the needs of Japanese cancer survivors. © The Author 2017.

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

    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.

    The HL7 SGML/XML Special Interest Group is developing the HL7 Document Patient Record Architecture. This draft proposal strives to create a common data architecture for the interoperability of healthcare documents. Key components are that it is under the umbrella of HL7 standards, it is specified in Extensible Markup Language, the semantics are drawn from the HL7 Reference Information Model, and the document specifications form an architecture that, in aggregate, define the semantics and structural constraints necessary for the exchange of clinical documents. The proposal is a work in progress and has not yet been submitted to HL7's formal balloting process.

    Information in society and in health care is currently undergoing a transition from paper to digital formats, and the main source of information will probably be electronic in the future. To explore patients' use and perceptions of the patient information leaflet included in the medication package, and their attitude towards a transition to an electronic version. The data was collected during October to November 2014 among individuals in South-Eastern Sweden, using a questionnaire (n=406, response rate 78%) and interviews (n=15). The questionnaire showed that the majority of the respondents (52%) occasionally read the patient information leaflet, 37% always read it, and 11% never read it. Almost half of the patients (41%) were positive towards reading the patient information leaflet electronically while 32% were hesitant and 26% neutral. A majority of the patients would request to get the patient information leaflet printed at the pharmacy if it was not included in the package. There were differences in attitude related to age and gender. The interviews showed that patients had mixed views on a transition to an electronic patient information leaflet. The patients perceived several positive aspects with an electronic patient information leaflet but were concerned about elderly patients. Although many were positive towards reading the patient information leaflet electronically, the majority prefer the patient information leaflet in paper form. Providing appropriate and useful eHealth services for patients to access the patient information leaflet electronically, along with education, could prepare patients for a transition to electronic patient information leaflet.

    Building an evidence base for healthcare interventions has long been advocated as both professionally and ethically desirable. By supporting meaningful comparison amongst different approaches, a good evidence base has been viewed as an important element in optimising clinical decision-making and the safety and quality of care. Unsurprisingly, medical research has put considerable effort into supporting the development of this evidence base, and the randomised controlled trial has become the dominant methodology. Recently however, a body of research has begun to question, not just this methodology per se, but also the extent to which the evidence it produces may marginalise individual patient experiences, priorities and perceptions.Simultaneously, the widespread adoption and utilisation of information systems (IS) in health care has also prompted initiatives to develop a stronger base of evidence about their impacts. These calls have been stimulated both by numerous system failures and research expressing concerns about the limitations of information systems methodologies in health care environments. Alongside the potential of information systems to produce positive, negative and unintended consequences, many measures of success, impact or benefit appear to have little to do with improvements in care, health outcomes or individual patient experiences.Combined these methodological concerns suggest the need for more detailed examination. This is particularly the case, given the prevalence within contemporary clinical and IS discourses on health interventions advocating the need to put the 'patient at the centre' by engaging them in their own care and/or 'empowering' them through the use of information systems.This paper aims to contribute to these on-going debates by focusing on the socio-technical processes by which patients' interests and outcomes are measured, defined and evaluated within health interventions that involve them using web-based information systems

    Many people living with Chronic Obstructive Pulmonary Disease (COPD) have low general health literacy; however, there is little information available on these patients' eHealth literacy, or their ability to seek, find, understand, and appraise online health information and apply this knowledge to address or solve disease-related health concerns. A nationally representative sample of patients registered in the COPD Foundation's National Research Registry (N = 1,270) was invited to complete a web-based survey to assess socio-demographic (age, gender, marital status, education), health status (generic and lung-specific health-related quality of life), and socio-cognitive (social support, self-efficacy, COPD knowledge) predictors of eHealth literacy, measured using the 8-item eHealth literacy scale (eHEALS). Over 50% of the respondents (n = 176) were female (n = 89), with a mean age of 66.19 (SD = 9.47). Overall, participants reported moderate levels of eHealth literacy, with more than 70% feeling confident in their ability to find helpful health resources on the Internet. However, respondents were much less confident in their ability to distinguish between high- and low-quality sources of web-based health information. Very severe versus less severe COPD (β = 4.15), lower lung-specific health-related quality of life (β = -0.19), and greater COPD knowledge (β = 0.62) were significantly associated with higher eHealth literacy. Higher COPD knowledge was also significantly associated with greater knowledge (ρ = 0.24, p = .001) and use (ρ = 0.24, p = .001) of web-based health resources. Findings emphasize the importance of integrating skill-building activities into comprehensive patient education programs that enable patients with severe cases of COPD to identify high-quality sources of web-based health information. Additional research is needed to understand how new social technologies can be used to help medically underserved COPD patients

    This study describes Internet use by breast cancer patients highlighting search patterns and examining the impact of web-based information on the clinical encounter. From September 2011 to January 2012, breast cancer patients at a cancer center completed a survey. Answers were closed and open-ended. Eighty-one patients were approached and 56 completed the survey. Forty-five (80 %) respondents used the Internet and 32 (71 %) searched for breast cancer information. All used Google as their principal search engine. To evaluate quality, 47 % referred to author credentials and 41 % examined references. Most sought information with respect to treatment or prognosis. Eighty percent felt that the information increased their knowledge and influenced treatment decision making for 53 %. This study highlights search patterns and factors used by breast cancer patients in seeking web-based information. Physicians must appreciate that patients use the Internet and address discrepancies between information sought and that which is available.

    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.

    To develop a Tablet-based Symbol Digit Modalities Test (T-SDMT) and to examine the test-retest reliability and concurrent validity of the T-SDMT in patients with stroke. The study had two phases. In the first phase, six experts, nine college students and five outpatients participated in the development and testing of the T-SDMT. In the second phase, 52 outpatients were evaluated twice (2 weeks apart) with the T-SDMT and SDMT to examine the test-retest reliability and concurrent validity of the T-SDMT. The T-SDMT was developed via expert input and college student/patient feedback. Regarding test-retest reliability, the practise effects of the T-SDMT and SDMT were both trivial (d=0.12) but significant (p≦0.015). The improvement in the T-SDMT (4.7%) was smaller than that in the SDMT (5.6%). The minimal detectable changes (MDC%) of the T-SDMT and SDMT were 6.7 (22.8%) and 10.3 (32.8%), respectively. The T-SDMT and SDMT were highly correlated with each other at the two time points (Pearson's r=0.90-0.91). The T-SDMT demonstrated good concurrent validity with the SDMT. Because the T-SDMT had a smaller practise effect and less random measurement error (superior test-retest reliability), it is recommended over the SDMT for assessing information processing speed in patients with stroke. Implications for Rehabilitation The Symbol Digit Modalities Test (SDMT), a common measure of information processing speed, showed a substantial practise effect and considerable random measurement error in patients with stroke. The Tablet-based SDMT (T-SDMT) has been developed to reduce the practise effect and random measurement error of the SDMT in patients with stroke. The T-SDMT had smaller practise effect and random measurement error than the SDMT, which can provide more reliable assessments of information processing speed.

    Meeting the psychosocial needs of vulnerable groups such as cancer survivors remains an ongoing challenge. This is particularly so for those who have less access to the usual forms of medical specialist and in-person support networks. Internet-based approaches offer an opportunity to better meet patients' information and support needs by overcoming the barrier of geographic isolation. The aim of the study was to assess the reported level of access to the Internet, preferred sources of information, and preferred sources of support among survivors of hematologic cancers. A population-based, Australian state cancer registry invited eligible survivors to complete a survey about psychosocial needs, including items measuring Internet access and patterns of use. Of the 732 eligible survivors invited to participate, 268 (36.6%) completed and returned the pen-and-paper-based survey. The majority of participants (186/254, 73.2%) reported a high level of access to the Internet, with higher Internet access associated with a higher level of education, larger household, younger age, and being married or employed. A total of 62.2% (156/251) of survivors indicated they were likely to use the Internet for accessing information, with the percentage much lower (69/251, 28%) for accessing support via the Internet. Likelihood of using the Internet for support was associated with feeling anxious and being employed. While the Internet appears to offer promise in increasing equitable access to information and support for cancer survivors for both metropolitan and regional areas, it is viewed less favorably for support and by particular subgroups (eg, older people and those without a university degree) within the survivor population. Promoting greater understanding of this mode of support may be required to achieve its potential. Information and support options other than Web-based approaches may continue to be needed by vulnerable groups of cancer survivors.

    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. 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.

    This virtual issue (VI) has been assembled to coincide with the 8th Annual Patient Information Conference 2013 organised by the UK Patient Information Forum (PiF). The conference theme 'Information and support - a service in its own right' is a response to policy documents and initiatives in both Scotland and England which signal the coming of age of patient/consumer information. The VI consists of a collection of open access articles and addresses the question 'What can health science librarians do to ensure that the public are able to find, appraise and use health information?' This material provides research evidence, and examples of the types of initiatives librarians have undertaken to make information a health and care service in its own right. Two recurrent messages are that health science librarians need to form partnerships with healthcare providers and they have a role to play in improving health literacy skills. © 2013 The authors.

  1. LEGAL BASES FOR DISCLOSING CONFIDENTIAL PATIENT INFORMATION FOR PUBLIC HEALTH: DISTINGUISHING BETWEEN HEALTH PROTECTION AND HEALTH IMPROVEMENT.

    The disclosure of confidential patient data without an individual's explicit consent should be for purposes that persons have reason to both expect and accept. We do not currently have the required level of clarity or consistency in understanding regarding the disclosure of confidential patient information for public health purposes to support effective public dialogue. The Health Service (Control of Patient Information) Regulations 2002 establish a legal basis in England and Wales for data to be disclosed for public health purposes without patient consent. Under the Regulations, there is more than one potential route towards lawful processing: Data may be processed for public health purposes under both Regulations 3 and 5. The alternatives have different safeguards and conditions attached, and their respective applicability to processing for purposes of public health improvement is currently unclear and subject to review. Beyond the need for clarity regarding the safeguards applicable to processing for particular public health purposes, there are reasons to prefer recognition that Regulation 5 is the most appropriate legal basis for disclosure when the purpose is public health improvement rather than public health protection. Where health improvement, rather than protection, is the aim, there is no justification for discarding the additional safeguards associated with processing under Regulation 5. © The Author 2015.

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

    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.

    Full Text Available 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.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.Comorbidities receive little attention in chronic disease trials.

    The use of information communication technology (ICT)-based tailored health management program can have significant health impacts for cancer patients. Information provision, health-related quality of life (HRQOL), and decision conflicts were analyzed for their relationship with need for an ICT-based personalized health management program in Korean cancer survivors. The health program needs of 625 cancer survivors from two Korean hospitals were analyzed in this cross-sectional study. Multivariate logistic regression was used to identify factors related to the need for an ICT-based tailored health management system. Association of the highest such need with medical information experience, HRQOL, and decision conflicts was determined. Furthermore, patient intentions and expectations for a web- or smartphone-based tailored health management program were investigated. Cancer survivors indicated high personalized health management program needs. Patients reporting the highest need included those with higher income (adjusted odds ratio [aOR], 1.70; 95% [confidence interval] CI, 1.10-2.63), those who had received enough information regarding helping themselves (aOR, 1.71; 95% CI, 1.09-2.66), and those who wished to receive more information (aOR, 1.59; 95% CI, 0.97-2.61). Participants with cognitive functioning problems (aOR, 2.87; 95%CI, 1.34-6.17) or appetite loss (aOR, 1.77; 95% CI, 1.07-2.93) indicated need for a tailored health care program. Patients who perceived greater support from the decision-making process also showed the highest need for an ICT-based program (aOR, 0.49; 95% CI, 0.30-0.82). We found that higher income, information provision experience, problematic HRQOL, and decisional conflicts are significantly associated with the need for an ICT-based tailored self-management program.

    Stage is a key predictor of cancer survival. Complete cancer staging is vital for understanding outcomes at population level and monitoring the efficacy of early diagnosis initiatives. Cancer registries usually collect details of the disease extent but staging information may be missing because a stage was never assigned to a patient or because it was not included in cancer registration records. Missing stage information introduce methodological difficulties for analysis and interpretation of results. We describe the associations between missing stage and socio-demographic and clinical characteristics of patients diagnosed with colon, lung or breast cancer in England in 2013. We assess how these associations change when completeness is high, and administrative issues are assumed to be minimal. We estimate the amount of avoidable missing stage data if high levels of completeness reached by some Clinical Commissioning Groups (CCGs), were achieved nationally. Individual cancer records were retrieved from the National Cancer Registration and linked to the Routes to Diagnosis and Hospital Episode Statistics datasets to obtain additional clinical information. We used multivariable beta binomial regression models to estimate the strength of the association between socio-demographic and clinical characteristics of patients and missing stage and to derive the amount of avoidable missing stage. Multivariable modelling showed that old age was associated with missing stage irrespective of the cancer site and independent of comorbidity score, short-term mortality and patient characteristics. This remained true for patients in the CCGs with high completeness. Applying the results from these CCGs to the whole cohort showed that approximately 70% of missing stage information was potentially avoidable. Missing stage was more frequent in older patients, including those residing in CCGs with high completeness. This disadvantage for older patients was not explained fully by the

    Fault detection and isolation, (FDI) of parametric faults in dynamic systems will be considered in this paper. An active fault diagnosis (AFD) approach is applied. The fault diagnosis will be investigated with respect to different information levels from the external inputs to the systems....... These inputs are disturbance inputs, reference inputs and auxilary inputs. The diagnosis of the system is derived by an evaluation of the signature from the inputs in the residual outputs. The changes of the signatures form the external inputs are used for detection and isolation of the parametric faults....

    This paper presents a patient's confidential data hiding scheme in electrocardiogram (ECG) signal and its subsequent wireless transmission. Patient's confidential data is embedded in ECG (called stego-ECG) using chaotic map and the sample value difference approach. The sample value difference approach effectually hides the patient's confidential data in ECG sample pairs at the predefined locations. The chaotic map generates these predefined locations through the use of selective control parameters. Subsequently, the wireless transmission of the stego-ECG is analyzed using the Orthogonal Frequency Division Multiplexing (OFDM) system in a Rayleigh fading scenario for telemedicine applications. Evaluation of proposed method on all 48 records of MIT-BIH arrhythmia ECG database demonstrates that the embedding does not alter the diagnostic features of cover ECG. The secret data imperceptibility in stego-ECG is evident through the statistical and clinical performance measures. Statistical measures comprise of Percentage Root-mean-square Difference (PRD), Peak Signal to Noise Ratio (PSNR), and Kulback-Leibler Divergence (KL-Div), etc. while clinical metrics includes wavelet Energy Based Diagnostic Distortion (WEDD) and Wavelet based Weighted PRD (WWPRD). The various channel Signal-to-Noise Ratio scenarios are simulated for wireless communication of stego-ECG in OFDM system. The proposed method over all the 48 records of MIT-BIH arrhythmia database resulted in average, PRD = 0.26, PSNR = 55.49, KL-Div = 3.34 × 10 -6 , WEDD = 0.02, and WWPRD = 0.10 with secret data size of 21Kb. Further, a comparative analysis of proposed method and recent existing works was also performed. The results clearly, demonstrated the superiority of proposed method.

    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. 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. 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. 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 comprehensive (85%, 17/20). Significant

    To identify distressed patients in oncology using screening questionnaires is quite challenging in clinical routine. Up to now there is no evidence based recommendation which instrument is most suitable and how to put a screening to practice. Using computer based screening tools offers the possibility to automatically analyse patient's data, inform psycho-oncological and medical staff about the results, and use reactive questionnaires. Studies on how to empower patients in decision making in psycho-oncology are rare.Methods Women with breast and gynaecological cancer have been consecutively included in this study (n=103) at time of inpatient surgical treatment in a gynaecological clinic. They answered the computer based screening questionnaire (ePOS-react) for routine distress screening at time of admission. At the end of the tool an individual recommendation concerning psycho-oncological treatment is given ( i) psycho-oncological counselling, ii) brief psycho-oncological contact, iii) no treatment suggestion). The informed patients could choose autonomously either the recommended treatment or an individually more favoured alternative possibility. Additionally, a clinical interview (approx. 30 min) based on the "Psychoonkologische Basisdiagnostik (PO-Bado)" has been carried out for a third-party assessment of patients' need for treatment.Results 68.9% followed the treatment recommendation. 22.3% asked for a more "intense" (e. g. counselling instead of recommended brief contact) and 8,7% for a "less intense" intervention than recommended. The accordance of third-party assessment (clinical interview "PO-Bado") and treatment recommendation is about 72.8%. The accordance of third-party assessment and patient's choice (ePOS-react) is about 58.3%. The latter is smaller because 29.1% asked for a brief psycho-oncological contact for whom from the third-party assessment's perspective no indication for treatment has been existent.Discussion A direct response of the

    Previous research has examined the impact of patient narratives on treatment choices, but to our knowledge, no study has examined the effect of narratives on information search. Further, no research has considered the relative impact of their format (text vs video) on health care decisions in a single study. Our goal was to examine the impact of video and text-based narratives on information search in a Web-based patient decision aid for early stage breast cancer. Fifty-six women were asked to imagine that they had been diagnosed with early stage breast cancer and needed to choose between two surgical treatments (lumpectomy with radiation or mastectomy). Participants were randomly assigned to view one of four versions of a Web decision aid. Two versions of the decision aid included videos of interviews with patients and physicians or videos of interviews with physicians only. To distinguish between the effect of narratives and the effect of videos, we created two text versions of the Web decision aid by replacing the patient and physician interviews with text transcripts of the videos. Participants could freely browse the Web decision aid until they developed a treatment preference. We recorded participants' eye movements using the Tobii 1750 eye-tracking system equipped with Tobii Studio software. A priori, we defined 24 areas of interest (AOIs) in the Web decision aid. These AOIs were either separate pages of the Web decision aid or sections within a single page covering different content. We used multilevel modeling to examine the effect of narrative presence, narrative format, and their interaction on information search. There was a significant main effect of condition, P=.02; participants viewing decision aids with patient narratives spent more time searching for information than participants viewing the decision aids without narratives. The main effect of format was not significant, P=.10. However, there was a significant condition by format interaction on

    To determine whether emergency department patients want to share their medical records across health systems through Health Information Exchange and if so, whether they prefer to sign consent or share their records automatically, 982 adult patients presenting to an emergency department participated in a questionnaire-based interview. The majority (N = 906; 92.3%) were willing to share their data in a Health Information Exchange. Half (N = 490; 49.9%) reported routinely getting healthcare outside the system and 78.6 percent reported having records in other systems. Of those who were willing to share their data in a Health Information Exchange, 54.3 percent wanted to sign consent but 90 percent of those would waive consent in the case of an emergency. Privacy and security were primary concerns of patients not willing to participate in Health Information Exchange and preferring to sign consent. Improved privacy and security protections could increase participation, and findings support consideration of "break-the-glass" provider access to Health Information Exchange records in an emergent situation.

    Understanding the informational needs of cancer patients is a requirement to plan any educative care program for them. The aim of this study was to identify Iranian cancer patients' perceptions of informational needs. The study took a qualitative approach. Semi-structured interviews were held with 25 cancer patients in two teaching hospitals in Iran. Transcripts of the interviews underwent conventional content analysis, and categories were extracted. The results came under two main categories: disease-related informational needs and information needs related to daily life. Disease-related informational needs had two subcategories: obtaining information about the nature of disease and obtaining information about disease prognosis. Information needs related to daily life also had two subcategories: obtaining information about healthy lifestyle and obtaining information about regular activities of daily life. The findings provide deep understanding of cancer patients' informational needs in Iran.

    Full Text Available Background: Information in society and in health care is currently undergoing a transition from paper to digital formats, and the main source of information will probably be electronic in the future. Objective: To explore patients’ use and perceptions of the patient information leaflet included in the medication package, and their attitude towards a transition to an electronic version. Methods: The data was collected during October to November 2014 among individuals in South-Eastern Sweden, using a questionnaire (n=406, response rate 78% and interviews (n=15. Results: The questionnaire showed that the majority of the respondents (52% occasionally read the patient information leaflet, 37% always read it, and 11% never read it. Almost half of the patients (41% were positive towards reading the patient information leaflet electronically while 32% were hesitant and 26% neutral. A majority of the patients would request to get the patient information leaflet printed at the pharmacy if it was not included in the package. There were differences in attitude related to age and gender. The interviews showed that patients had mixed views on a transition to an electronic patient information leaflet. The patients perceived several positive aspects with an electronic patient information leaflet but were concerned about elderly patients. Conclusion: Although many were positive towards reading the patient information leaflet electronically, the majority prefer the patient information leaflet in paper form. Providing appropriate and useful eHealth services for patients to access the patient information leaflet electronically, along with education, could prepare patients for a transition to electronic patient information leaflet.

    Slowing down the progression of chronic kidney disease (CKD) and its adverse health outcomes requires the patient's self-management and attention to treatment recommendations. Information technology (IT)-based interventions are increasingly being used to support self-management in patients with chronic diseases such as CKD. We conducted a systematic review of randomized controlled trials (RCTs) to assess the features and effects of IT-based interventions on self-management outcomes of CKD patients. A comprehensive search was conducted in Medline, Scopus, and the Cochrane Library to identify relevant papers that were published until May 2016. RCT Studies that assessed at least one automated IT tool in patients with CKD stages 1 to 5, and reported at least one self-management outcome were included. Studies were appraised for quality using the Cochrane Risk of Bias assessment tool. Out of 12,215 papers retrieved, eight study met the inclusion criteria. Interventions were delivered via smartphones/personal digital assistants (PDAs) (three studies), wearable devices (three studies), computerized systems (one study), and multiple component (one study). The studies assessed 15 outcomes, including eight clinical outcomes and seven process of care outcomes. In 12 (80%) of the 15 outcomes, the studies had revealed the effects of the interventions as statistically significant positive. These positive effects were observed in 75% of the clinical outcomes and 86% of the process of care outcomes. The evidence indicates the potential of IT-based interventions (i.e. smartphones/PDAs, wearable devices, and computerized systems) in self-management outcomes (clinical and process of care outcomes) of CKD patients.

    We tested the feasibility and efficacy of an electronic health record (EHR) strategy that automated the delivery of print medication information at the time of prescribing. Patients (N=141) receiving a new prescription at one internal medicine clinic were recruited into a 2-arm physician-randomized study. We leveraged an EHR platform to automatically deliver 1-page educational 'MedSheets' to patients after medical encounters. We also assessed if physicians counseled patients via patient self-report immediately following visits. Patients' understanding was objectively measured via phone interview. 122 patients completed the trial. Most intervention patients (70%) reported receiving MedSheets. Patients reported physicians frequently counseled on indication and directions for use, but less often for risks. In multivariable analysis, written information (OR 2.78, 95% CI 1.10-7.04) and physician counseling (OR 2.95, 95% CI 1.26-6.91) were independently associated with patient understanding of risk information. Receiving both was most beneficial; 87% of those receiving counseling and MedSheets correctly recalled medication risks compared to 40% receiving neither. An EHR can be a reliable means to deliver tangible, print medication education to patients, but cannot replace the salience of physician-patient communication. Offering both written and spoken modalities produced a synergistic effect for informing patients. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    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).

    Informal caregivers (CGs) of patients with Alzheimer's disease are at risk of suffering from psychological and physical weakening. Several psychoeducational interventions have been designed to prevent stress and burden of caregivers. In France, despite health authorities' recommendations, to our knowledge there is no rigorously assessed Web-based psychoeducational program to date. The objective of our study was to assess the efficacy of a French Web-based psychoeducational program (called Diapason) with an unblinded randomized clinical trial. In this protocol, 80 informal caregivers of patients followed at Broca Hospital are recruited offline and randomized in the experimental condition (EC) or the control condition (CC). The volunteers in EC have to visit a closed online user group at least once a week and validate one new session of this fully automated Web program, during 12 weeks. Each week a new thematic is added to the website. The participants in the CC receive usual care, and have access to the Diapason program after their participation (6 months). Face-to-face evaluations for both groups are planned every 3 months (M0-M3 and M6). The main objective of this program is to provide CGs with information on the disease process, how to prevent psychological strain (using anticipation and relaxation techniques), and offering a virtual space (forum) to discuss with other caregivers. The primary outcome of this study is the self-perceived stress, while self-efficacy, burden, depression, and self-perceived health status are defined as secondary outcomes. Other variables that might have an impact on the program efficacy are collected. This protocol was accepted for funding. The enrollment began in October 2011, and participants currently recruited will finish their evaluations in January 2014. The results are expected for June 2014. Findings might provide empirical evidence on: (1) the feasibility of an Internet-based program in the French context, (2) the

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 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.

    The purpose of this study was to analyze the decay of information with multiple sequential patient handoff reports given by third-year medical students who have not had standardized patient handoff training. We examine the information decay of quantitative parameters included in 2 different simulated patient history and physical handoffs conducted among third-year medical students. Both student self-surveys and third party observer surveys tracked accuracy of information. A total of 93 students were surveyed for the first patient scenario and 103 students were surveyed for second patient scenario. Survey data were aggregated into 2 separate spreadsheets, one for each patient scenario tested. A total of 16 data points pertaining to the checklist were analyzed for common trends in handoff accuracy and information decay. Quantitative analysis of information passed between handoffs showed that between the 2 case scenarios, there was a consistent loss of information between one presenter to the next. Overall, 33% of information was lost between the first and third handoffs. Within the progression of individual handoffs, a narrative decay was demonstrated. There was a regression in handoff accuracy, trending down to an average of only 45% of information being passed on successfully by the time each presenter reached the last piece of information in their patient presentation. When examining the survey data points that had greater than an 80% success rate of being included in the handoffs, there appeared to be no correlation between their inherent qualities. This study showed there is a significant decrease in accuracy of information during sequential patient handoff exercises. The information decay may be a result of time, memory, or relevance of the information to the student. Future studies incorporating teaching effective handoffs early in the clinical curriculum would be an area of future research. Copyright © 2014 Association of Program Directors in Surgery

    The decision to undergo bariatric surgery is multifactorial and made both by patient and doctor. Information is of the utmost importance for this decision. To investigate the bariatric surgery patient's preferences regarding information provision in bariatric surgery. A teaching hospital, bariatric center of excellence in Amsterdam, the Netherlands. All patients who underwent a primary laparoscopic Roux-en-Y gastric bypass or sleeve gastrectomy between September 2013 and September 2014 were approached by mail to participate. A questionnaire was used to elicit patient preferences for the content and format of information. Sociodemographic characteristics, clinicopathologic factors, and psychologic factors were explored as predictors for specific preferences. Of the 356 eligible patients, 112 (31.5%) participated. The mean age was 49.2 (±10.7) years, and 91 (81.3%) patients were female. Patients deemed the opportunity to ask questions (96.4%) the most important feature of the consult, followed by a realistic view on expectations-for example, results of the procedure (95.5%) and information concerning the consequences of surgery for daily life (89.1%). Information about the risk of complications on the order of 10% was desired by 93% of patients; 48% desired information about lower risks (.1%). Only 25 patients (22.3%) desired detailed information concerning their weight loss after surgery. Bariatric patients wished for information about the consequences of surgery on daily life, whereas the importance of information concerning complications decreased when their incidence lessened.

    Issues related to lack of system usability and potential safety hazards continue to be reported in the health information technology (HIT) literature. Usability engineering methods are increasingly used to ensure improved system usability and they are also beginning to be applied more widely for ensuring the safety of HIT applications. These methods are being used in the design and implementation of many HIT systems. In this paper we describe evidence-based approaches to applying usability engineering methods. A multi-phased approach to ensuring system usability and safety in healthcare is described. Usability inspection methods are first described including the development of evidence-based safety heuristics for HIT. Laboratory-based usability testing is then conducted under artificial conditions to test if a system has any base level usability problems that need to be corrected. Usability problems that are detected are corrected and then a new phase is initiated where the system is tested under more realistic conditions using clinical simulations. This phase may involve testing the system with simulated patients. Finally, an additional phase may be conducted, involving a naturalistic study of system use under real-world clinical conditions. The methods described have been employed in the analysis of the usability and safety of a wide range of HIT applications, including electronic health record systems, decision support systems and consumer health applications. It has been found that at least usability inspection and usability testing should be applied prior to the widespread release of HIT. However, wherever possible, additional layers of testing involving clinical simulations and a naturalistic evaluation will likely detect usability and safety issues that may not otherwise be detected prior to widespread system release. The framework presented in the paper can be applied in order to develop more usable and safer HIT, based on multiple layers of evidence.

    Controversy still surrounds abortion and abortion care in many countries. Information for women who seek abortion is not always as objective and complete as desired. In Italy abortion has been legal for the last decades. The overall purpose of this study was to investigate general information needs among patients in a hospital in Rome. A questionnaire concerning information needs, opinions on information to include in a booklet, and methods of information was distributed among 212 women in a public hospital in Rome. Women answered the questionnaire very differently, and general information needs were not shown to be as essential as expected; their present needs seemed especially underestimated. However, a booklet with information as objective and complete as possible is suggested as a way of giving information to abortion patients.

    Consent to treatment lies at the heart of autonomous decision making by patients who are entitled to make a free choice about whether to accept or refuse treatment. To help patients arrive at their decision district nurses must ensure that they give sufficient information about the nature and risks inherent in the treatment to allow an informed choice to be made. This article considers how much information regarding risks needs to be disclosed. It discusses how the law requires a different level of disclosure for patients who ask no questions about risks, those who make general enquiries about risks and those who ask specific questions about the risks inherent in treatment.

    Prognostic information is necessary for cancer patients to be fully informed about the likely course of their disease. This information is needed for practical planning and treatment decisions. This study sought to examine how cancer patients understand the prognosis information available to them. The setting is an urban safety net hospital. Six focus groups with cancer patients (N = 39) were digitally recorded and transcribed verbatim then analyzed using phases of content analysis. Participants in all groups discussed the prognosis almost exclusively in terms of mortality and reported that their physicians and nurses mostly provided prognostic information in terms of months or years for survival. This finding held across all cancer types and stages. Patients tend to think of prognosis information as being only estimated limited survival and find the idea upsetting. Due to this view on prognosis, patients need further explanation regarding where the prognosis information comes from and what prognostic information can tell them in order to make use of it.

  11. Context based multimedia information retrieval

    Mølgaard, Lasse Lohilahti

    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...... topics from a large collection of the transcribed speech to improve retrieval of spoken documents. The context modelling is done using a variant of probabilistic latent semantic analysis (PLSA), to extract properties of the textual sources that refl ect how humans perceive context. We perform PLSA...... of Wikipedia , as well as text-based semantic similarity. The final aspect investigated is how to include some of the structured data available in Wikipedia to include temporal information. We show that a multiway extension of PLSA makes it possible to extract temporally meaningful topics, better than using...

    In response to the dearth of consumer health information for patients with gastrointestinal cancers, this study examined the informational needs of these patients to build a plan for future resource development. Although studies have examined informational needs of some such cancers, no published literature has investigated the comprehensive informational needs across all sites of gastrointestinal cancer. A cross-sectional needs assessment comprising a self-administered questionnaire was conducted at an ambulatory gastrointestinal oncology clinic in Toronto, Canada. Patient informational needs were measured, including importance of information, amount desired and preferred mode of delivery. Informational needs were grouped into six domains: medical, practical, physical, emotional, social and spiritual. Eighty-two surveys were analysed. The majority of the respondents were male (53.8%), over the age of 50 (77.8%), and born outside of Canada (51.9%). While many did not speak English as a child (46.3%), and do not speak English at home (22.2%), nearly all indicated comfort with receiving health information in English (97.5%). The majority of respondents were college educated (79.3%) and married (73%). Multiple cancer types were reported; the most common being colorectal (39%), followed by pancreatic (12%) and cancers of the gallbladder or bile duct (12%). Overall, respondents placed highest importance on medical information (P < 0.001). Preferred education modalities were pamphlets, websites and one-on-one discussions with health-care professionals. This study highlights the principal informational needs of patients with gastrointestinal malignancies, along with preferred modality for information delivery. This information will guide the development of educational resources for future patients. © 2014 John Wiley & Sons Ltd.

    2012-07-01

    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. The term 'hydrocephalus' was searched for on the search engines http://www.google.com/, http://www.bing.com/ and http://www.yahoo.com/. The top 20 results of these searches were assessed using the University of Michigan consumer health website evaluation checklist. 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. 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.

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

    Electronic patient records facilitate the provision of safe, high-quality medical care. However, because personnel can view almost all stored information, this study designed a display method using a mosaic blur (pixelation) to temporarily conceal information patients do not want shared. This study developed an electronic patient records display method for patient information that balanced the patient's desire for personal information protection against the need for information sharing among medical personnel. First, medical personnel were interviewed about the degree of information required for both individual duties and team-based care. Subsequently, they tested a mock display method that partially concealed information using a mosaic blur, and they were interviewed about the effectiveness of the display method that ensures patient privacy. Participants better understood patients' demand for confidentiality, suggesting increased awareness of patients' privacy protection. However, participants also indicated that temporary concealment of certain information was problematic. Other issues included the inconvenience of removing the mosaic blur to obtain required information and risk of insufficient information for medical care. Despite several issues with using a display method that temporarily conceals information according to patient privacy needs, medical personnel could accept this display method if information essential to medical safety remains accessible.

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

  17. Ontology-based Information Retrieval

    DEFF Research Database (Denmark)

    Styltsvig, Henrik Bulskov

    In this thesis, we will present methods for introducing ontologies in information retrieval. The main hypothesis is that the inclusion of conceptual knowledge such as ontologies in the information retrieval process can contribute to the solution of major problems currently found in information...... retrieval. This utilization of ontologies has a number of challenges. Our focus is on the use of similarity measures derived from the knowledge about relations between concepts in ontologies, the recognition of semantic information in texts and the mapping of this knowledge into the ontologies in use......, as well as how to fuse together the ideas of ontological similarity and ontological indexing into a realistic information retrieval scenario. To achieve the recognition of semantic knowledge in a text, shallow natural language processing is used during indexing that reveals knowledge to the level of noun...

  18. Biological information systems: Evolution as cognition-based information management.

    Science.gov (United States)

    Miller, William B

    2018-05-01

    An alternative biological synthesis is presented that conceptualizes evolutionary biology as an epiphenomenon of integrated self-referential information management. Since all biological information has inherent ambiguity, the systematic assessment of information is required by living organisms to maintain self-identity and homeostatic equipoise in confrontation with environmental challenges. Through their self-referential attachment to information space, cells are the cornerstone of biological action. That individualized assessment of information space permits self-referential, self-organizing niche construction. That deployment of information and its subsequent selection enacted the dominant stable unicellular informational architectures whose biological expressions are the prokaryotic, archaeal, and eukaryotic unicellular forms. Multicellularity represents the collective appraisal of equivocal environmental information through a shared information space. This concerted action can be viewed as systematized information management to improve information quality for the maintenance of preferred homeostatic boundaries among the varied participants. When reiterated in successive scales, this same collaborative exchange of information yields macroscopic organisms as obligatory multicellular holobionts. Cognition-Based Evolution (CBE) upholds that assessment of information precedes biological action, and the deployment of information through integrative self-referential niche construction and natural cellular engineering antecedes selection. Therefore, evolutionary biology can be framed as a complex reciprocating interactome that consists of the assessment, communication, deployment and management of information by self-referential organisms at multiple scales in continuous confrontation with environmental stresses.

    2014-01-01

    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.

    2010-01-01

    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

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

    Directory of Open Access Journals (Sweden)

    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

    This study aimed to use the Patient Reported Information Multidimensional Exploration (PRIME) framework, a novel ensemble of machine-learning and deep-learning algorithms, to extract, analyze, and correlate self-reported information from Online Cancer Support Groups (OCSG) by patients (and partners of patients) with low intermediate-risk prostate cancer (PCa) undergoing radical prostatectomy (RP), external beam radiotherapy (EBRT), and active surveillance (AS), and to investigate its efficacy in quality-of-life (QoL) and emotion measures. From patient-reported information on 10 OCSG, the PRIME framework automatically filtered and extracted conversations on low intermediate-risk PCa with active user participation. Side effects as well as emotional and QoL outcomes for 6084 patients were analyzed. Side-effect profiles differed between the methods analyzed, with men after RP having more urinary and sexual side effects and men after EBRT having more bowel symptoms. Key findings from the analysis of emotional expressions showed that PCa patients younger than 40 years expressed significantly high positive and negative emotions compared with other age groups, that partners of patients expressed more negative emotions than the patients, and that selected cohorts ( 70 years, partners of patients) have frequently used the same terms to express their emotions, which is indicative of QoL issues specific to those cohorts. Despite recent advances in patient-centerd care, patient emotions are largely overlooked, especially in younger men with a diagnosis of PCa and their partners. The authors present a novel approach, the PRIME framework, to extract, analyze, and correlate key patient factors. This framework improves understanding of QoL and identifies low intermediate-risk PCa patients who require additional support.

    The diagnosis of pathologies from signal processing approaches has shown to be of importance. This can provide noninvasive information at the earliest stage. In this work, the problem of categorising - in a quantifiable manner - information content of microvascular blood flow signals recorded in healthy participants and patients with varicose veins is addressed. For this purpose, laser Doppler flowmetry (LDF) signals - that reflect microvascular blood flow - recorded both at rest and after acetylcholine (ACh) stimulation (an endothelial-dependent vasodilator) are analyzed. Each signal is processed with the empirical mode decomposition (EMD) to obtain its intrinsic mode functions (IMFs). An entropy measure of each IMFs is then computed. The results show that IMFs of LDF signals have different complexity for different physiologic/pathological states. This is true both at rest and after ACh stimulation. Thus, the proposed framework (EMD + entropy computation) may be used to gain a noninvasive understanding of LDF signals in patients with microvascular dysfunctions. Copyright © 2015 IPEM.

    Information product qualitative forming and effective use is the aim of any information technology. Information technology as a system provides both computer-aided problem solving for the user and automation of information processes, which in turn support the problem solving process. That's why the information technology methods are the methods for data transmission, processing, and storage. The tools of methodology, mathematics, algorithms, hardware, software, and information are the tools of information technology. We propose to differ between global, basic, and applied information technologies depending on information product significance and characteristics of models, methods, and tools used. The global technology is aimed to use information resources in the social sphere as a whole. The basic technology is oriented on the application sphere (industry, scientific research, design, training). Transition towards new information technology should have in its concern business area model merged with the formal model of problem solving: computing organization based on the data concept; user's intellectual interface development.

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

    Most patients needing intensive care cannot give informed consent to participation in research. This includes the most acutely and severely ill, with the highest mortality and morbidity where research has the greatest potential to improve patient outcomes. In these circumstances consent is usually sought from a substitute decision maker, but while survivors of intensive care believe substitute decision makers will look after their interests, evidence suggests substitute decision makers are poorly equipped for this task. Various models have been suggested for research without patient informed consent when intervention is urgent and cannot wait until first person consent is possible, including a waiver of consent if conditions are met. A nationally consistent model is proposed for Australia with a robust process for initial waiver of consent followed by first person consent to further research-related procedures or ongoing follow-up when this can be competently provided.

    To determine the information that terminal cancer patients have about their diagnosis, identifying key words used, and quantifying the conspiracy of silence. A cross-sectional, analytical study was conducted by reviewing the hospice support team data base which contains the medical history and a semi-structured interview with terminal cancer patients in the first visit to the hospice. Demographic and socioeconomic data was collected, as well as relevant clinical information (diagnosis, prevalent symptoms, number of symptoms, patient functionality, QoL, information given, and words used). Out of total of sample of 723 records, 77.87% (95% CI: 74.70-80.74) of the patients were properly informed about their diagnosis. The most used words were cancer in 26% of the patients, tumour in 51.59%, and for the remaining 10.65%, the word inflammation was used. Statistically significant differences of information were found between sexes, age, types of cancer, and hospital ward. Terminal cancer patients have knowledge on their diagnosis, suggesting that the conspiracy of silence is present to a lesser extent. This knowledge is transmitted using different words and with euphemisms. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

    To reduce the cost of health care while increasing efficiency and quality, health systems are seeking innovative means to engage and empower patients. Improved use of information technology and electronic health record (EHR) infrastructure is essential, and required for "meaningful use" as mandated by the federal government. Providing personalized health information using tablets at the point of care could enhance the clinical experience and enable efficient collection of patient reported outcome measures to guide clinical decision making. The aim of this study is to explore patient and provider attitudes and interest in a proposed clinic-based tablet system for personal health information exchange. To provide a context to understand patients' use of tablets during their clinic visit, we also examine patients' current activities and time spent in the waiting room, and their use of health information resources. Surveys were administered to 84 patients in the waiting room of a community health center affiliated with Massachusetts General Hospital (MGH) in Boston, MA. This survey included a vignette and illustration describing a proposed tablet-based system in which the patient, upon sign in at the clinic, receives a tablet loaded with personalized information tailored to their specific medical conditions and preferences. Patients were queried about their interest in such a system in comparison to traditional forms of patient education as well as their current health information seeking behaviors and activities and time spent in the waiting room. Interviews with five MGH-affiliated health care providers were conducted to assess their opinions regarding the proposed tablet system. The majority (>60%) of patients were "very" or "extremely" interested in the proposed tablet system and thought it would improve their knowledge about their medical condition (60%), assist them in making healthy choices (57%), and help them to feel more comfortable talking with their provider

    To discover missed opportunities for providing information to women undergoing breast reconstruction in an effort to decrease regret and improve patient education, teaching modalities, and satisfaction. Thirty- to 45-minute semi-structured interviews were conducted exploring patient experiences with information provision on breast reconstruction. Purposeful sampling was used to include women with a variety of reconstruction types at different time points along their recovery. Using grounded theory methodology, 2 independent reviewers analyzed the transcripts and generated thematic codes based on patient responses. BREAST-Q scores were also collected to compare satisfaction scores with qualitative responses. Patients were interested in a wide variety of topics related to breast reconstruction including the pros and cons of different options, nipple-sparing mastectomies, immediate breast reconstruction, oncological safety/monitoring and the impact of chemotherapy and radiotherapy, secondary procedures (balancing, nipple reconstruction), post-operative recovery, and long-term expectations. Patients valued accessing information from multiple sources, seeing numerous photographs, being guided to reliable information online, and having access to a frequently asked questions file or document. Information delivery via interaction with medical personnel and previously reconstructed patients was most appreciated. Compared with BREAST-Q scores for satisfaction with the plastic surgeon (mean: 95.7, range: 60-100), informational satisfaction scores were lower at 74.7 (50-100), confirming the informational gaps expressed by interviewees. Women having recently undergone breast reconstruction reported key deficiencies in information provided prior to surgery and identified preferred information delivery options. Addressing women's educational needs is important to achieve appropriate expectations and improve satisfaction.

    Full Text Available Full training according to the information needs of patients reduces health care costs and increases the quality of care. The present study was conducted aims to prioritize the preferences of hemodialysis patients in acquisition of health information to be able to provide training according to these preferences and their prioritization after achieving them. This study was a descriptive cross-sectional one which was conducted on all hemodialysis patients who visited Kowsar Hospital in Semnan within the year 2014-2015. Data collecting tool was researcher-made questionnaire which assessed physical information needs of patients in four areas of nutrition, energy, pain and discomfort, sleep and rest. Data were analyzed by SPSS software version 16 using the descriptive statistics.71 hemodialysis patients participated in this study. 68.6%, 50.7%, 42.6% and 46.7% of patients expressed acquisition information regarding hematopoietic foods, how to increase mobility, how to relieve itching during dialysis and mental activities before sleep as their first priorities, respectively. The results of this study showed that hemodialysis patients need to know what kinds of information in the field of physical problems. To facilitate adaptation and selfcare of patients, providing information and training based on the real needs of patients will be helpful.

    We describe the medication information-seeking behaviors of arthritis patients' partners and explore whether partner medication information-seeking and information-sharing are associated with patient medication adherence. Arthritis patients and their partners (n = 87 dyads) completed an on-line questionnaire. Partners indicated how often they obtained medication information from 14 sources, how much they trusted these sources, and whether they shared medication information with the patient. Patients reported their medication adherence. Bivariate associations were calculated to explore the relationships between partner information-seeking, information-sharing, and patient medication adherence. Partners sought little information about the patient's medications. Partners sought more information if the patient's medication regimen was more complex (r = 0.33, p = 0.002). Most partners (∼ 98%) shared medication information with the patient; older partners shared more information with the patient (r = 0.25, p = 0.03). Neither partner information-seeking (r = 0.21, p = 0.06) nor partner information-sharing (r = 0.12, p = 0.31) were significantly associated with patient medication adherence. Although partners of arthritis patients do not seek large amounts of medication information, the vast majority share this information with the patient. Involving partners in medical consultations can help them better understand the patient's medications, have questions answered by providers, and engage in more informed discussions with patients about their medications.

    2015-01-01

    To construct a comprehensive vaccine information ontology that can support personal health information applications using patient-consumer lexicon, and lead to outcomes that can improve patient education. The authors composed the Vaccine Information Statement Ontology (VISO) using the web ontology language (OWL). We started with 6 Vaccine Information Statement (VIS) documents collected from the Centers for Disease Control and Prevention (CDC) website. Important and relevant selections from the documents were recorded, and knowledge triples were derived. Based on the collection of knowledge triples, the meta-level formalization of the vaccine information domain was developed. Relevant instances and their relationships were created to represent vaccine domain knowledge. The initial iteration of the VISO was realized, based on the 6 Vaccine Information Statements and coded into OWL2 with Protégé. The ontology consisted of 132 concepts (classes and subclasses) with 33 types of relationships between the concepts. The total number of instances from classes totaled at 460, along with 429 knowledge triples in total. Semiotic-based metric scoring was applied to evaluate quality of the ontology.

    Patient-centered decision making requires cancer patients be actively involved and feel sufficiently informed about their care, but patients' preferences for information are often unrecognized or unmet by their oncologist, particularly for more distressing topics. This study examined cancer patients' preferences for information about three care-related topics: (1) diagnostic information, (2) treatment costs, and (3) prognosis. We tested whether factors known to influence information preferences (psychological distress, control preferences, and financial distress) were differently associated with information preferences for each topic. Cancer patients (N = 176) receiving ongoing treatment completed a questionnaire that assessed their out-of-pocket treatment costs, psychological distress, preferences for control over their medical decisions, and the amount of information they desired and received from their oncologists about the three topics. Patients' preferences were less often met for treatment cost information than for the other topics, p information than they received. One-third of patients also wanted more prognostic information than they received. Patients' preferences for diagnostic information did not differ as a function of financial burden, distress, or control preferences, ps > 0.05. Preferences for cost information were greater among patients who preferred more control over their medical decisions, p = 0.016. Patients' preferences for prognostic information were greater among those desiring more control and with lower distress, ps information preferences. Appreciating the variability in information preferences across topics and patients may aid efforts to meet patients' information needs and improve outcomes.

    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....

    2011-06-01

    Full Text Available Data bases are one of the most important components in every large informatics system which stores and processes data and information. Because data bases contain all of the valuable information about a company, its clients, its financial activity, they represent one of the key elements in the structure of an organization, which determines imperatives such as confidentiality, integrity and ease of data access. The current paper discuses the integrity of data bases and it refers to the validity and the coherence of stored data. Usually, integrity is defined in connection with terms of constraint, that are rules regarding coherence which the data base cannot infringe. Data base that integrity refers to information correctness and assumes to detect, correct and prevent errors that might have an effect on the data comprised by the data bases.

    2015-07-01

    Full Text Available Consumers and patients want to be included in decisions regarding their own health and have an ethically justified claim on informed decisions. Therefore, sound information is required, but health information is often misleading and based on different interests. The risks of disease and the benefits of medical interventions tend to be overestimated, whereas harm is often underestimated. Evidence-based health information has to fulfil certain criteria, for instance, it should be evidence-based, independent, complete, true as well as understandable. The aim of a medical intervention has to be explained. The different therapeutic options including the option not to intervene have to be delineated. The probabilities for success, lack of success and unwanted side effects have to be communicated in a numerical and understandable manner. Patients have the right to reject medical interventions without any sanctions.

    2015-01-01

    Patient-centered healthcare initiatives are underway to enable patients to take more responsibility for their healthcare. To do so, patients must be able to access, utilize, and share their health information. Access to health information through patient portals and other electronic means is increasing with the adoption of electronic health records (EHRs), but not all providers have EHRs or patient portals and not all information may be available electronically. Patients are expected to continue to request paper and electronic copies of their medical records. This research project was initiated to obtain up-to-date data regarding health information management (HIM) practices related to patients' access to their health information.

    2004-11-01

    This paper presents a method to assess drug treatment appropriateness, based on an original combination of economic analysis, pharmacoepidemiological techniques and evidence-based information. This method generates an index of clinical-economic appropriateness for the treatment under examination, by comparing the theoretically expected health gain (EHG) to the yearly national expenditure (EXPEND) on that drug and the amount of health that is thought to be gained in the 'real' patients (RHG). This paper reviews all the analyses conducted so far using this method, and discusses their main results. The primary aim of this article is to suggest a ranking approach for allocating the drug budgets of national health systems.

    Full Text Available Information systems begin to date increasingly faster because of rapidly changing business environment. Usually, small changes are not sufficient to adapt complex legacy information systems to changing business needs. A new functionality should be installed with the requirement of putting business data in the smallest possible risk. Information systems modernization problems are beeing analyzed in this paper and a method for information system modernization is proposed. It involves programming code transformation into abstract syntax tree metamodel (ASTM and model based transformation from ASTM into knowledge discovery model (KDM. The method is validated on example for SQL language.

    A novel Virtual Organization framework which incorporates wireless technology support is presented in the research work. The Virtual Organization is designed for a clinical environment to provide better patient information management and enhanced collaborative working of multidisciplinary care teams. The analysis studies the current clinical practices and looks at the general patient information resource structure currently in use for patient care. Based on this problem analysis and current requirements of the multi-disciplinary care team members, we propose a generic and sustainable Patient Centric Virtual Organization (PCVO) framework to complement the functionality of the existing infrastructure by incorporating wireless technologies support for improved patient information provision at the point of care. The preliminary results of the study identify and classify the specific point of care tasks suited to appropriate information resources needed by the care team members. This paper concentrates on the patient information management aspects brought in by incorporating wireless technologies at the point of care using patient information resources in a decentralized and distributed computing environment. This applied research is carried out in the secondary and tertiary care sector in the cancer domain. For the analysis and results of the pilot project, we have used a case study of a local NHS Cancer Hospital.

    Informed consent is crucial in therapeutic choices; however, the forms presented to patients are often locally developed and information may not be homogeneous. To prepare an evidence-based model for informed consent, applied in the case of erythropoietin therapy (EPO) as a teaching tool for medical students. Methodological tools of Evidence-Based Medicine (EBM) were developed within the EBM Course in the Medical School of Torino, Italy, as problem solving and patient information tools (5th year students work in small groups under the supervision of statisticians, epidemiologists and experts of internal medicine--nephrology in this case). Methodological and ethical problems were identified: in the pre-dialysis field, evidence from randomized clinical trials (RCT) is scant; how to use evidence gathered in dialysis? How to deal with implementation? How with the mass media? Do we need to discuss the drug choice with the patients? How to deal with rare and severe side effects?). The "evidence" was searched for on Medline/Embase, by using key-words and free terms. About 680 papers were retrieved and screened. Forms available on the Internet were retrieved and a general scheme was drawn: it included 5 areas: title, aim and targets (patients and family physicians); search strategies and updating; pros and cons of therapy; alternative options; open questions. EBM may offer valuable tools for systematically approaching patient information; the inclusion of this kind of exercise in the Medical School EBM courses may help enhance the awareness of future physicians of the correct communication with patients.

    BACKGROUND: Information seeking is an important coping mechanism for dealing with chronic illness. Despite a growing number of mental health websites, there is little understanding of how patients with bipolar disorder use the Internet to seek information. METHODS: A 39 question, paper......-based, anonymous survey, translated into 12 languages, was completed by 1222 patients in 17 countries as a convenience sample between March 2014 and January 2016. All patients had a diagnosis of bipolar disorder from a psychiatrist. Data were analyzed using descriptive statistics and generalized estimating...... search engine. The primary reasons for searching were drug side effects (51 %), to learn anonymously (43 %), and for help coping (39 %). About 1/3 rated their search skills as expert, and 2/3 as basic or intermediate. 59 % preferred a website on mental illness and 33 % preferred Wikipedia. Only 20 % read...

  15. Information theory based approaches to cellular signaling.

    2011-10-01

    Cells interact with their environment and they have to react adequately to internal and external changes such changes in nutrient composition, physical properties like temperature or osmolarity and other stresses. More specifically, they must be able to evaluate whether the external change is significant or just in the range of noise. Based on multiple external parameters they have to compute an optimal response. Cellular signaling pathways are considered as the major means of information perception and transmission in cells. Here, we review different attempts to quantify information processing on the level of individual cells. We refer to Shannon entropy, mutual information, and informal measures of signaling pathway cross-talk and specificity. Information theory in systems biology has been successfully applied to identification of optimal pathway structures, mutual information and entropy as system response in sensitivity analysis, and quantification of input and output information. While the study of information transmission within the framework of information theory in technical systems is an advanced field with high impact in engineering and telecommunication, its application to biological objects and processes is still restricted to specific fields such as neuroscience, structural and molecular biology. However, in systems biology dealing with a holistic understanding of biochemical systems and cellular signaling only recently a number of examples for the application of information theory have emerged.

    Multimodal visualization aims at fusing different data sets so that the resulting combination provides more information and understanding to the user. To achieve this aim, we propose a new information-theoretic approach that automatically selects the most informative voxels from two volume data sets. Our fusion criteria are based on the information channel created between the two input data sets that permit us to quantify the information associated with each intensity value. This specific information is obtained from three different ways of decomposing the mutual information of the channel. In addition, an assessment criterion based on the information content of the fused data set can be used to analyze and modify the initial selection of the voxels by weighting the contribution of each data set to the final result. The proposed approach has been integrated in a general framework that allows for the exploration of volumetric data models and the interactive change of some parameters of the fused data set. The proposed approach has been evaluated on different medical data sets with very promising results.

    2012-06-07

    The science of information systems, management, and interpretation plays an important part in the continuity of care of patients. This is becoming more evident in the treatment of human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS), the leading cause of death in sub-Saharan Africa. The high replication rates, selective pressure, and initial infection by resistant strains of HIV infer that drug resistance will inevitably become an important health care concern. This paper describes proposed research with the aim of developing a physician-administered, artificial intelligence-based decision support system tool to facilitate the management of patients on antiretroviral therapy. This tool will consist of (1) an artificial intelligence computer program that will determine HIV drug resistance information from genomic analysis; (2) a machine-learning algorithm that can predict future CD4 count information given a genomic sequence; and (3) the integration of these tools into an electronic medical record for storage and management. The aim of the project is to create an electronic tool that assists clinicians in managing and interpreting patient information in order to determine the optimal therapy for drug-resistant HIV patients.

    2015-08-01

    Anaesthesia has evolved in France since the last epidemiologic survey in 1996. The national database program for medical information systems (the PMSI) can be used to track specific knowledge concerning anaesthesia for a selected period of time. The goal of this study was to perform a contemporary epidemiological description of anaesthesia in France for the year 2010. The data concerning private or public hospital stays were collected from the national PMSI database. All surgical/medical institutions performing anaesthesia in France and French Overseas Departments and Territories were queried concerning the number of anaesthesias, patient age, sex ratios, institution characteristics, hospitalization types, the duration of hospital stays, and the surgical procedures performed. In 2010, the number of anaesthesia procedures performed was 11,323,630 during 8,568,630 hospital stays. We found that 9,544,326 (84.3%) anaesthetic procedures were performed in adults (> 18 years of age; excluding childbirth), 845,568 (7.5%) were related to childbirth and 933,736 (8.2%) were acts in children (up to 18 years of age). The mean duration of hospital stay was 5.7±8.2 days. 56.5% of adults and 39.5% of children were managed as inpatient hospital stays. The male/female sex ratio and mean age were 42/58 and 54±19 years, respectively. In adults, anaesthesia was predominantly performed for abdominal surgery (24.5%), orthopaedics (16.7%), gynaecology (10.3%), ophthalmology (9.7%) and vascular surgeries (7.1%). For paediatric populations, the main surgical activities were Ear-Nose-Throat surgery (43.1%), orthopaedic surgery (15.1%) and urological surgeries (12.8%). The number of anaesthesias performed in France has dramatically increased (42.7%) since the last major epidemiological survey. Anaesthesia in the 21th century has been adapted to associated demographic changes: an older population with more comorbidities and fewer in-hospital procedures. Copyright © 2015 Société fran

    The growing worldwide population has increased the need for technologies, computerised software algorithms and smart devices that can monitor and assist patients anytime and anywhere and thus enable them to lead independent lives. The real-time remote monitoring of patients is an important issue in telemedicine. In the provision of healthcare services, patient prioritisation poses a significant challenge because of the complex decision-making process it involves when patients are considered 'big data'. To our knowledge, no study has highlighted the link between 'big data' characteristics and real-time remote healthcare monitoring in the patient prioritisation process, as well as the inherent challenges involved. Thus, we present comprehensive insights into the elements of big data characteristics according to the six 'Vs': volume, velocity, variety, veracity, value and variability. Each of these elements is presented and connected to a related part in the study of the connection between patient prioritisation and real-time remote healthcare monitoring systems. Then, we determine the weak points and recommend solutions as potential future work. This study makes the following contributions. (1) The link between big data characteristics and real-time remote healthcare monitoring in the patient prioritisation process is described. (2) The open issues and challenges for big data used in the patient prioritisation process are emphasised. (3) As a recommended solution, decision making using multiple criteria, such as vital signs and chief complaints, is utilised to prioritise the big data of patients with chronic diseases on the basis of the most urgent cases.

    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.

    2011-10-15

    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.

    Information received by cancer patients has gained importance in recent decades. The aim of this study was to evaluate the perception of information received by oncological patients in a radiotherapy department and to measure the importance of the other information sources. A cross-sectional study was conducted, evaluating patients who received radiotherapy. All the patients were asked two questionnaires: the EORTC QLQ-INFO26 module evaluating their satisfaction with received information, and a questionnaire analyzing other sources of information search. One hundred patients between 27 and 84 years were enrolled. Breast cancer (26 %) was the commonest cancer. Patients felt better informed about the medical tests and secondly about the performed treatment. The younger patients were those who were more satisfied with the information received and patients with no formal education felt less satisfied, with statistically significant differences. Patients did not seek external information; at the most, they asked relatives and other people with cancer. Patients were satisfied with the received information, although a high percentage would like more information. In general, patients did not search for external information sources. Age and educational level seem to influence in the satisfaction with the received information.

    To develop effective ways of sharing patients' medical information, we developed a new medical information exchange system (MIES) based on a registry server, which enabled us to exchange different types of data generated by various systems. To assure that patient's medical information can be effectively exchanged under different system environments, we adopted the standardized data transfer methods and terminologies suggested by the Center for Interoperable Electronic Healthcare Record (CIEHR) of Korea in order to guarantee interoperability. Regarding information security, MIES followed the security guidelines suggested by the CIEHR of Korea. This study aimed to develop essential security systems for the implementation of online services, such as encryption of communication, server security, database security, protection against hacking, contents, and network security. The registry server managed information exchange as well as the registration information of the clinical document architecture (CDA) documents, and the CDA Transfer Server was used to locate and transmit the proper CDA document from the relevant repository. The CDA viewer showed the CDA documents via connection with the information systems of related hospitals. This research chooses transfer items and defines document standards that follow CDA standards, such that exchange of CDA documents between different systems became possible through ebXML. The proposed MIES was designed as an independent central registry server model in order to guarantee the essential security of patients' medical information.

    In this paper we present a framework to define transfer functions from a target distribution provided by the user. A target distribution can reflect the data importance, or highly relevant data value interval, or spatial segmentation. Our approach is based on a communication channel between a set of viewpoints and a set of bins of a volume data set, and it supports 1D as well as 2D transfer functions including the gradient information. The transfer functions are obtained by minimizing the informational divergence or Kullback-Leibler distance between the visibility distribution captured by the viewpoints and a target distribution selected by the user. The use of the derivative of the informational divergence allows for a fast optimization process. Different target distributions for 1D and 2D transfer functions are analyzed together with importance-driven and view-based techniques. © 2010 IEEE

    Given the poor prognosis of esophageal cancer and the impact of surgery on health-related quality of life (HRQL), addressing patients' postoperative information needs is important. This study aimed to examine (1) the content and type of patients' information needs and (2) patient perceived facilitators and barriers to patient participation. Interviews were conducted with 20 purposefully selected esophageal cancer patients. Open and structured questions were alternated. The transcribed interviews were analysed inductively and deductively, using MAXqda. Patients' post-operative information needs concerned HRQL, medical care and prognosis, covering several sub-domains. Different types of needs were identified, e.g., requests for information about cause, course and self-management. Barriers to patient participation mostly reflected beliefs and skills, and could be categorized into agenda and communication barriers. Facilitators of patient participation reflected physician, patient and interaction characteristics, companion support and pre-visit preparation. Many patients saw merit in pre-visit preparation interventions; few endorsed skill-building interventions. This study listed the postoperative information needs of esophageal cancer patients. Moreover, it gained insight into patient-perceived barriers and facilitators of patient participation. The findings demonstrate what information physicians should have available and informs interventions to support patients in meeting their information needs. Copyright © 2011 Elsevier Ireland Ltd.

    Full Text Available Abstract Background In the post-genomic era several methods of computational genomics are emerging to understand how the whole information is structured within genomes. Literature of last five years accounts for several alignment-free methods, arisen as alternative metrics for dissimilarity of biological sequences. Among the others, recent approaches are based on empirical frequencies of DNA k-mers in whole genomes. Results Any set of words (factors occurring in a genome provides a genomic dictionary. About sixty genomes were analyzed by means of informational indexes based on genomic dictionaries, where a systemic view replaces a local sequence analysis. A software prototype applying a methodology here outlined carried out some computations on genomic data. We computed informational indexes, built the genomic dictionaries with different sizes, along with frequency distributions. The software performed three main tasks: computation of informational indexes, storage of these in a database, index analysis and visualization. The validation was done by investigating genomes of various organisms. A systematic analysis of genomic repeats of several lengths, which is of vivid interest in biology (for example to compute excessively represented functional sequences, such as promoters, was discussed, and suggested a method to define synthetic genetic networks. Conclusions We introduced a methodology based on dictionaries, and an efficient motif-finding software application for comparative genomics. This approach could be extended along many investigation lines, namely exported in other contexts of computational genomics, as a basis for discrimination of genomic pathologies.

    To explore patients' attitudes towards the PINK video, a patient education video aimed at encouraging hospital patients' involvement in safety-relevant behaviours. Qualitative semi-structured interviews. Detailed field notes were taken during the interviews which were analysed using content analysis. One National Health System (NHS) teaching hospital based in London, UK. Thirty-six in-patients aged between 20 and 79 years, 18 of them males. The PINK video is a short animated educational video aimed at encouraging patients to be involved in the safety of their care during hospitalization. Patients' perceptions of how informative, relevant and acceptable the video is; attitudes towards participating in the recommended safety-related behaviours and; potential negative side effects of watching the video. Overall the video was received favourably among the interviewees. Commonly cited benefits included raising awareness and facilitating patients to be involved in their care during their hospital stay. More variability was found in participants' views with regard to the video's role as a patient safety enhancement tool. A number of suggestions for improvement of the video were provided relating to tailoring its content and design to meet the needs of individual patients and their circumstances. Educational videos such as PINK have significant potential to empower patients in the safety and quality of their care. However, efforts to implement patient safety educational videos in practice need to consider different patient groups' needs and characteristics instead of trying to adopt 'a one size fits all' approach.

  18. Fast mutual-information-based contrast enhancement

    2017-07-01

    Recently, T. Celik proposed an effective image contrast enhancement (CE) method based on spatial mutual information and PageRank (SMIRANK). According to the state-of-the-art evaluation criteria, it achieves the best visual enhancement quality among existing global CE methods. However, SMIRANK runs much slower than the other counterparts, such as histogram equalization (HE) and adaptive gamma correction. Low computational complexity is also required for good CE algorithms. In this paper, we novelly propose a fast SMIRANK algorithm, called FastSMIRANK. It integrates both spatial and gray-level downsampling into the generation of pixel value mapping function. Moreover, the computation of rank vectors is speeded up by replacing PageRank with a simple yet efficient row-based operation of mutual information matrix. Extensive experimental results show that the proposed FastSMIRANK could accelerate the processing speed of SMIRANK by about 20 times, and is even faster than HE. Comparable enhancement quality is preserved simultaneously.

    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.

    Understanding patients' knowledge and prior information-seeking regarding personalized cancer therapy (PCT) may inform future patient information systems, consent for molecular testing and PCT protocols. We evaluated breast cancer patients' knowledge and information-seeking behaviors regarding PCT. Newly registered female breast cancer patients (n=100) at a comprehensive cancer center completed a self-administered questionnaire prior to their first clinic visit. Knowledge regarding cancer genetics and PCT was moderate (mean 8.7±3.8 questions correct out of 16). A minority of patients (27%) indicated that they had sought information regarding PCT. Higher education (p=0.009) and income levels (p=0.04) were associated with higher knowledge scores and with seeking PCT information (p=0.04). Knowledge was not associated with willingness to participate in PCT research. Educational background and financial status impact patient knowledge as well as information-seeking behavior. For most patients, clinicians are likely to be patients' initial source of information about PCT. Understanding patients' knowledge deficits at presentation may help inform patient education efforts.

    Implanted ports are frequently used for patients with cancer who require IV chemotherapy. In addition to verbal communication with healthcare providers, patients with cancer may benefit from written information. This pre/post study evaluated the effectiveness of an informational booklet by improving knowledge about ports and assessed the history, need, and preferences for information. Patients with cancer who had an implanted port for at least six months were provided with an informational booklet about ports. Knowledge about ports was tested before (T0) and after (T1) patients read the booklet. Information needs and preferred sources of information were also assessed at T0. Patients reported their opinions of the booklet at T1. The sample included 129 patients; 49% were male, with a mean age of 59 years. Most patients want to receive as much information as possible, preferably before the port is implanted. However, 43% of patients reported they had received little information about ports. After reading the booklet, patients' knowledge, which was measured with a validated seven-item instrument, improved from T0 to T1 (p information, can increase patients' knowledge about implanted ports and their confidence in caring for their ports.

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

  4. Information Filtering Based on Users' Negative Opinions

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

    Information received by IBD patients about their disease is of particular importance. The objective of the study was to determine the information resources these patients used, together with their perceived information gaps and expected preferences. A prospective, observational, cross-sectional study conducted on IBD patients attending 13 Spanish hospitals during 2008. Patients completed a semi-structured 52-question survey. Survey was adequately completed by 379 of 385 patients (98%), of whom 57% had Crohn's disease and 43% ulcerative colitis. Mean patient age was 37.9 years (range, 16-76 years). Gastroenterologists were the most commonly used resource (98%), followed by the Internet (60%), and general practitioners (50%). More than 90% reported good to excellent satisfaction with gastroenterologists, nurses, and patients' associations. Only 56% considered their information needs to be covered. The Internet was mostly used by young patients and those with a high education level. In the future, 85% of the patients would like to receive information from the gastroenterologists, and 92% by face-to-face interviews. Patients mainly want additional information on treatment (medical and surgical), clinical manifestations, cancer, and mortality risks. They also think that they are poorly informed about their social and work rights, risks of cancer and death, and research trials. Patients with IBD use and prefer gastroenterologists as the main source of information, but only half of them consider their information needs to be covered.

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

    The aim of this project was to produce audiovisual patient information, which was user friendly and fit for purpose. The purpose of the audiovisual patient information is to inform patients about randomized controlled trials, as a supplement to their trial-specific written information sheet. Audiovisual patient information is known to be an effective way of informing patients about treatment. User involvement is also recognized as being important in the development of service provision. The aim of this paper is (i) to describe and discuss the process of developing the audiovisual patient information and (ii) to highlight the challenges and opportunities, thereby identifying implications for practice. A future study will test the effectiveness of the audiovisual patient information in the cancer clinical trial setting. An advisory group was set up to oversee the project and provide guidance in relation to information content, level and delivery. An expert panel of two patients provided additional guidance and a dedicated operational team dealt with the logistics of the project including: ethics; finance; scriptwriting; filming; editing and intellectual property rights. Challenges included the limitations of filming in a busy clinical environment, restricted technical and financial resources, ethical needs and issues around copyright. There were, however, substantial opportunities that included utilizing creative skills, meaningfully involving patients, teamworking and mutual appreciation of clinical, multidisciplinary and technical expertise. Developing audiovisual patient information is an important area for nurses to be involved with. However, this must be performed within the context of the multiprofessional team. Teamworking, including patient involvement, is crucial as a wide variety of expertise is required. Many aspects of the process are transferable and will provide information and guidance for nurses, regardless of specialty, considering developing this

    Background Patients make a crucial contribution to undergraduate medical education. Although a national resource is available for patients participating in research, none is as yet available for education. Aim This study aimed to explore what information patients would like about participation in general practice based undergraduate medical education, and how they would like to obtain this information. Design and setting Two focus groups were conducted in London-based practices involved in both undergraduate and postgraduate teaching. Method Patients both with and without teaching experience were recruited using leaflets, posters, and patient participation groups. An open-ended topic guide explored three areas: perceived barriers that participants anticipated or had experienced; patient roles in medical education; and what help would support participation. Focus groups were audiorecorded, transcribed, and analysed thematically. Results Patients suggested ways of professionalising the teaching process. These were: making information available to patients about confidentiality, iterative consent, and normalising teaching in the practice. Patients highlighted the importance of relationships, making information available about their GPs’ involvement in teaching, and initiating student–patient interactions. Participants emphasised educational principles to maximise exchange of information, including active participation of students, patient identification of student learner needs, and exchange of feedback. Conclusion This study will inform development of patient information resources to support their participation in teaching and access to information both before and during general practice based teaching encounters.

    2011-05-01

    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.

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

    Now more than ever, cancer patients want health information. Little has been published to characterize the information needs and preferred sources of that information for patients who have completed cancer treatment. We used a nationally validated instrument to prospectively survey patients attending a cancer clinic for a post-treatment follow-up visit. All patients who came to the designated clinics between December 2011 and June 2012 were approached (N = 648), and information was collected only from those who agreed to proceed. The 411 patients who completed the instrument included individuals with a wide range of primary malignancies. Their doctor or health professional was overwhelmingly the most trusted source of cancer information, followed by the Internet, family, and friends. The least trusted sources of information included radio, newspaper, and television. Patients most preferred to receive personalized written information from their health care provider. Cancer survivors are keenly interested in receiving information about cancer, despite having undergone or finished active therapy. The data indicate that, for patients, their health care provider is the most trusted source of cancer information. Cancer providers should ask patients about the information they want and should direct them to trusted sources.

    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.

  17. Painters and patients: how art informs medicine.

    Science.gov (United States)

    Wear, D

    1991-01-01

    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.

    Full Text Available Abstract Background Discrepancies between the information that patients have received and the patients' awareness of their condition have frequently been observed in literature and given a number of different explanations. The chief contribution of this study is that by following patients over time it is possible not only to notice any changes in the patients' knowledge or awareness of their disease, but also to investigate the interview material for possible reasons for those changes. Since the study is based on two different groups of patients it will also be possible to notice if the category of disease matters for patients' awareness of their condition. Methods Twelve patients with malign haematological diseases or lung cancer were followed with interviews from diagnosis to cure or death, or at most for two years. The method is qualitative. Semi-structured interviews were conducted, transcribed into written text, and then used for a qualitative content analysis. Results During the process of analysis four different expressions (subcategories emerged about the awareness of patients concerning their health status: informed and aware, not informed and not aware, aware though not informed, or not aware though informed. Then the search started for obstacles to the awareness of patients regarding their progressing disease and approaching death. Four kinds of obstacles were found: due to the physician, the patient, the physician and the patient in collusion, or neither to the physician nor the patient but the insidious way in which lung cancer (mostly and haematological malignancies (occasionally progress. Conclusion To optimize the care of patients who wish to be informed and aware during their disease, it is important that the health care staff recognizes potential obstacles to the awareness of patients in order to minimize such obstacles. The physicians could improve their communication with patients with life-threatening diseases, and avoid

    Patients, as one of the most prominent groups requiring health-based information, encounter numerous problems in order to obtain these pieces of information and apply them. The aim of this study was to determine the information-seeking behavior of cardiovascular patients who were hospitalized in Isfahan University of Medical Sciences hospitals. This is a survey research. The population consisted of all patients with cardiovascular disease who were hospitalized in the hospitals of Isfahan University of Medical Sciences during 2012. According to the statistics, the number of patients was 6000. The sample size was determined based on the formula of Cochran; 400 patients were randomly selected. Data were collected by researcher-made questionnaire. Two-level descriptive statistics and inferential statistics were used for analysis. The data showed that the awareness of the probability to recover and finding appropriate medical care centers were the most significant informational needs. The practitioners, television, and radio were used more than the other informational resources. Lack of familiarity to medical terminologies and unaccountability of medical staff were the major obstacles faced by the patients to obtain information. The results also showed that there was no significant relationship between the patients' gender and information-seeking behavior, whereas there was a significant relationship between the demographic features (age, education, place of residence) and information-seeking behavior. Giving information about health to the patients can help them to control their disease. Appropriate methods and ways should be used based on patients' willingness. Despite the variety of information resources, patients expressed medical staff as the best source for getting health information. Information-seeking behavior of the patients was found to be influenced by different demographic and environmental factors.

    The number of participants in medical experiments has declined and consent often rests on perilous ground because the participant information sheet (PIS) on which informed consent rests preserves identification with the expert environment. This study explores to which extent research ethics committee (REC) members appreciate this problem. A retrospective analysis of ten REC applications were subjected to a naïve reading followed by structural analysis to generate themes and subthemes to guide structured REC member focusgroup interviews. This analysis informed a prospective survey where REC members registered terms and phrases posing comprehension barriers to lay receivers. Main barriers of comprehension were aspects of contents presentation and specialised terminology. Problematic terms centred mainly on epidemiology, design, descriptive and topographic anatomy and physiology, diagnostic procedures and medicines. Contents problems centred on irrelevant and superfluous information and poor presentation. The language, structure and format of the PIS should be improved. Avoiding technical jargon or explaining it when it is used, using more common words when they are available and a clearer structure were identified as potential targets of intervention. not relevant. not relevant.

    Patient care problems arise when health care consumers and professionals find health information on the Internet because that information is often inaccurate. To mitigate this problem, nurses can develop Web literacy and share that skill with health care consumers. This study evaluated a Web-literacy intervention for undergraduate nursing students to find reliable Web-based health information. A pre- and postsurvey queried undergraduate nursing students in an informatics course; the intervention comprised lecture, in-class practice, and assignments about health Web site evaluation tools. Data were analyzed using Wilcoxon and ANOVA signed-rank tests. Pre-intervention, 75.9% of participants reported using Web sites to obtain health information. Postintervention, 87.9% displayed confidence in using an evaluation tool. Both the ability to critique health Web sites (p = .005) and confidence in finding reliable Internet-based health information (p = .058) increased. Web-literacy education guides nursing students to find, evaluate, and use reliable Web sites, which improves their ability to deliver safer patient care. [J Nurs Educ. 2017;56(2):110-114.].

    Two hundred forty-nine newly diagnosed hypertensive patients prescribed thiazide medication were recruited for study. Two-thirds were given a leaflet or patient package insert (PPI) that described the drug and its possible side effects, and one-third were not. At a revisit about 1 month later, patients were asked whether they had experienced any of 17 different health problems. For each problem that they experienced, they were asked whether they thought the problem was related to the medicine they were taking. Ten of the health problems were taken verbatim from the PPI's list of possible drug side effects. Patients who received the PPI reported experiencing about the same number of side effects as the non-PPI subjects. However, those who received the PPI were more likely to attribute experienced reactions to the drug. This was true for both reactions specifically listed in the PPI and for similar reactions not listed. Results support the notion of an attribution-labeling process rather than a suggestion effect.

    The ruling by the French Court of Cassation dated February 25, 1997 obliged doctors to provide proof of the information given to patients, reversing more than half a century of case law. In October 1997, it was specified that such evidence could be provided by "all means", including presumption. No hierarchy in respect of means of proof has been defined by case law or legislation. The present study analyzed judicial decisions with a view to determining the means of proof liable to carry the most weight in a suit for failure to provide due patient information. A retrospective qualitative study was conducted for the period from January 2010 to December 2015, by a search on the LexisNexis ® JurisClasseur website. Two hundred and one judicial decisions relating to failure to provide due patient information were selected and analyzed to study the characteristics of the practitioners involved, the content of the information at issue and the means of proof provided. The resulting cohort of practitioners was compared with the medical demographic atlas of the French Order of Medicine, considered as exhaustive. Two hundred and one practitioners were investigated for failure to provide information: 45 medical practitioners (22±3%), and 156 surgeons (78±3%) including 45 orthopedic surgeons (29±3.6% of surgeons). Hundred and ninety-three were private sector (96±1.3%) and 8 public sector (4±1.3%). Hundred and one surgeons (65±3.8% of surgeons), and 26 medical practitioners (58±7.4%) were convicted. Twenty-five of the 45 orthopedic surgeons were convicted (55±7.5%). There was no significant difference in conviction rates between surgeons and medical practitioners: odds ratio, 1.339916; 95% CI [0.6393982; 2.7753764] (Chi 2 test: p=0.49). Ninety-two practitioners based their defense on a single means of proof, and 74 of these were convicted (80±4.2%). Forty practitioners based their defense on several means of proof, and 16 of these were convicted (40±7.8%). There was

    Patient education (PE) is as important as medical and surgical interventions in the management of diabetic foot ulcer (DFU). Patient information leaflets (PILs) are globally accepted patient counseling aids. This study aimed at developing PILs for DFU patients and investigating its validation. The PILs were prepared based on different model leaflets available from various online resources, including "Patient UK". The PILs readability was evaluated by Flesch/ Flesch-Kincaid readability (FRE/FK-GL) method before user-testing (n = 34 DFU patients) by quasi-experimental methods in patients with DFU. Additionally, user-opinion on legibility and content of the PIL was also determined. Baker Able Leaflet Design (BALD) method was employed to assess the layout and design characteristics of the PIL. The best FRE score achieved was 73.9 and the FK-GL score was 6.1. The mean BALD assessment score for English and Kannada versions of PIL were 27 and 26, respectively. The ICC of the test-retest reliability of user-testing and user-opinion questionnaires in both English and Kannada ranged from 0.91 to 0.96. The overall user-testing knowledge-based mean score significantly improved from 43.4 to 69.7 (P < 0.05). Overall, 82.4% of patients reported overall user-opinion on legibility and content of the PIL as good. The developed PILs met the criteria of fairly easy readability and good layout design. The user-opinion of the majority of patients reported the PIL content, legibility, and design as good. The Pictogram-based PILs (P-PILs) was found to be an effective PE tool in DFU patients.

    The Institute of Medicine recommends Survivorship Care Plans (SCPs) for all cancer survivors. However, it is unclear whether certain patient groups may or may not benefit from SCPs. The aim was to assess whether the effects of an automatically generated paper SCP on patients' satisfaction with information provision and care, illness perceptions, and health care utilization were moderated by disease-related Internet use. Twelve hospitals were randomized to either SCP care or usual care in the pragmatic cluster randomized Registrationsystem Oncological GYnecology (ROGY) Care trial. Newly diagnosed endometrial cancer patients completed questionnaires after diagnosis (N=221; response: 74.7%, 221/296), 6 months (n=158), and 12 months (n=147), including patients' satisfaction with information provision and care, illness perceptions, health care utilization (how many times patients visited a medical specialist or primary care physician about their cancer in the past 6 months), and disease-related Internet use (whether patients used the Internet to look for information about cancer). In total, 80 of 221 (36.2%) patients used the Internet to obtain disease-related information. Disease-related Internet use moderated the SCP care effect on the amount of information received about the disease (P=.03) and medical tests (P=.01), helpfulness of the information (P=.01), and how well patients understood their illness (P=.04). All stratified analyses were not statistically significant. However, it appeared that patients who did not seek disease-related information on the Internet in the SCP care arm reported receiving more information about their disease (mean 63.9, SD 20.1 vs mean 58.3, SD 23.7) and medical tests (mean 70.6, SD 23.5 vs mean 64.7, SD 24.9), finding the information more helpful (76.7, SD 22.9 vs mean 67.8, SD 27.2; scale 0-100), and understanding their illness better (mean 6.6, SD 3.0 vs mean 6.1, SD 3.2; scale 1-10) than patients in the usual care arm did.

    Current access control mechanisms of the hospital information system can hardly identify the real access intention of system users. A relaxed access control increases the risk of compromise of patient privacy. To reduce unnecessary access of patient information by hospital staff, this paper proposes a Knowledge-Constrained Role-Based Access Control (KC-RBAC) model in which a variety of medical domain knowledge is considered in access control. Based on the proposed Purpose Tree and knowledge-involved algorithms, the model can dynamically define the boundary of access to the patient information according to the context, which helps protect patient privacy by controlling access. Compared with the Role-Based Access Control model, KC-RBAC can effectively protect patient information according to the results of the experiments.

    The medical information becomes integrated into a communications strategy, the generally admitted model of which is centered on the patient; that is in the listening of these concerns and these values. The medical quality information is facilitated by the preliminary collection of the symptoms and the needs of the patients thanks to the questionnaires of quality of life, if they are used during the consultation to direct the discussion. Satisfactory medical information includes a discussion about the questions of the patients in terms of outcomes. Patient's individual factors can influence the need of medical information, as the age and the pathology. Patient's needs can also vary with time and according to the phase of the disease. Cultural factors are essential, in particular as regards the information about prognosis. Tools to help giving the medical information are now validated as the audio cassettes or video. Those tools can take the shape of a prompt list to help patients to ask questions. The majority preference of style of participation in the medical and therapeutic decisions and is the collaborative mode. Physician's attitude is determinant to leave the patients who wish it to have an active role, what allows them a very beneficial feeling psychologically of control over the disease. Decision-making helps are successfully sometimes elaborated to support the participation of the patients. In palliative phase, the need of medical information about prognosis associated with preservation of hope is not still understood by physicians who oscillate between saying the all or none. Honest information at the right time is the majority wish of the patients, although certain patients adopt clearly a strategy of avoidance. The medical communication requires a specific training on this subject. Talking time must be opened to the doctors to approach the relational problems which they meet. The clinical research has to continue to understand better the interactions in

    2010-01-01

    Objectives The aim of this study was to compare patient satisfaction with the pre-operative information before and after explaining the radiograph and to compare patient satisfaction with the radiographic information when based on a digital or a conventional image, as well as on extraoral or intraoral images. Methods 263 patients (with 301 mandibular third molars) were given pre-operative information by one of two trained scholar students before removal of the third molar. The course of the surgery and possible post-operative complications and risks were explained to the patient. The patients rated their satisfaction with the information on a 100 mm visual analogue scale (VAS). The radiograph was displayed and the radiographic information was explained to the patient, with emphasis on tooth-specific risk factors. The patients again rated their satisfaction on a VAS. Results There was no significant difference in patient satisfaction score before (mean VAS = 92.5 mm) and after (mean VAS = 91.7 mm) the radiographic information was explained (P = 0.15). No difference in satisfaction was found between patients who were shown either digital or conventional images or between patients who were shown either extraoral or intraoral images (P > 0.5). Conclusions No additional patient satisfaction was obtained by showing and explaining the radiograph to the patient before lower third molar surgery. If the dentist still wishes to show the patient the radiograph, the type of image seems not to be important. PMID:20203280

    To evaluate quality and readability of Internet-based information on halitosis. An Internet search through 3 engines (Google, Yahoo, and Bing) was done with the terms ("bad breath," "halitosis," "oral malodor," "foul breath," "mouth malodor," "breath malodor," "fetor ex ore," "fetor oris," "ozostomia," and "stomatodysodia"). The first 50 websites from each engine resulting from each search term were screened. Included websites were evaluated using Health on the Net (HON) criteria, Journal of American Medical Association (JAMA) benchmarks, DISCERN, Ensuring Quality Information for Patients (EQIP), Flesch Reading Ease (FRE) score, and Flesch-Kincaid Grade level. A total of 101 websites were included. HON, DISCERN, EQIP, and FRE score were 42.9%, 37.6%, 37.4%, and 51.9% of the maximum score, respectively. Fewer than 50% of sites displayed attribution, disclosure, and currency according to JAMA benchmarks. HON score, DISCERN score, and EQIP score had significant correlation with each other and were significantly higher in sites displaying the HON seal. The current quality and readability of informative websites on halitosis are generally low and poorly organized. Clinicians should be able to assess the Internet-based information on halitosis, as well as give accurate advice and guide patients concerning this issue. Copyright © 2017 Elsevier Inc.

    2017-12-01

    Since the original Institute of Medicine (IOM) report was published there has been an accelerated development and adoption of health information technology with varying degrees of evidence about the impact of health information technology on patient safety.  This article is intended to review the current available scientific evidence on the impact of different health information technologies on improving patient safety outcomes. We conclude that health information technology improves patient's safety by reducing medication errors, reducing adverse drug reactions, and improving compliance to practice guidelines. There should be no doubt that health information technology is an important tool for improving healthcare quality and safety. Healthcare organizations need to be selective in which technology to invest in, as literature shows that some technologies have limited evidence in improving patient safety outcomes.

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

    Consent remains a crucial, yet challenging, cornerstone of clinical practice. The ethical, legal and professional understandings of this construct have evolved away from a doctor-centred act to a patient-centred process that encompasses the patient's values, beliefs and goals. This alignment of consent with the philosophy of shared decision-making was affirmed in a recent high-profile Supreme Court ruling in England. The communication of information is central to this model of health care delivery but it can be difficult for doctors to gauge the information needs of the individual patient. The aim of this paper is to describe 'core information sets' which are defined as a minimum set of consensus-derived information about a given procedure to be discussed with all patients. Importantly, they are intended to catalyse discussion of subjective importance to individuals. The model described in this paper applies health services research and Delphi consensus-building methods to an idea orginally proposed 30 years ago. The hypothesis is that, first, large amounts of potentially-important information are distilled down to discrete information domains. These are then, secondly, rated by key stakeholders in multiple iterations, so that core information of agreed importance can be defined. We argue that this scientific approach is key to identifying information important to all stakeholders, which may otherwise be communicated poorly or omitted from discussions entirely. Our methods apply systematic review, qualitative, survey and consensus-building techniques to define this 'core information'. We propose that such information addresses the 'reasonable patient' standard for information disclosure but, more importantly, can serve as a spring board for high-value discussion of importance to the individual patient. The application of established research methods can define information of core importance to informed consent. Further work will establish how best to incorporate

    Breast cancer is the most common cancer in women both around the world and in Iran. By studying the information needs of patients with breast cancer, the quality of the information provided for them can be improved. This study investigated the information needs of breast cancer patients and their information-seeking behavior. This cross-sectional study was conducted from March to June, 2015. The research population was 120 women diagnosed with breast cancer and informed about their disease who referred to oncology outpatient clinics at a specialized cancer hospital and a radiotherapy oncology center in Mashhad (the only specialized cancer centers in eastern and northeastern Iran). Average participant age was 46.2 years (SD = 9.9). Eighty-five percent of patients desired more information about their disease. Results showed that the attending physician (mean = 3.76), television health channel (mean = 3.30), and other patients (mean = 3.06) were the most popular sources of information for breast cancer patients. Patients stated their strongest reasons for using information sources as achieving a better understanding of the disease (mean = 3.59), less anxiety (mean = 3.92), and curiosity to learn more about the disease (mean = 3.66), sequentially. Results further indicated that disease management (mean = 4.18) and nutritional options during treatment (mean = 4.14) were the most often mentioned areas in which patients required information, while knowing the progress rate of their disease was the least (mean = 3.73). It seems necessary to have a good, organized plan to provide breast cancer patients with information and increase their information literacy, one of their undeniable rights.

    Providing information related to medication has many benefits for patients. However, patients' conflicting perceptions about medical information provided by physicians and pharmacists may be associated with their psychological distress regarding treatment and medication. This study investigated associations between patients' perceptions of agreement between physicians and pharmacists about medical information and improvements in their psychological distress. It also clarified the specific relationships of their perceptions with psychological distress. A cross-sectional survey was conducted in Japanese community pharmacy settings. Pharmacists approached 1,500 patients visiting community pharmacies and provided them with questionnaire packages. Patients completed the questionnaires at home and returned them to the researchers by mail. Multivariate logistic regression analysis and signal detection analysis were conducted to examine associations of patients' perceptions of information agreement with improvement in psychological distress. Measures of improvement in worry and anxiety about disease, improvement in worry and anxiety about medication, and improvement in depressive mood were used to assess alleviation of psychological distress. A total of 645 patients returned the questionnaires; 628 contributed to the data. Multivariate logistic regression analyses clarified that patients' perceptions of agreement in information regarding need for medication, methods for adverse drug reaction reduction, adverse drug reaction symptoms, coping with forgetting to take medication, and advice for daily life were significantly associated with improvements in psychological distress. Furthermore, signal detection analysis showed that several combinations of patients' perceptions of agreement between physicians and pharmacists about specific medical information were also significantly associated with improvement in psychological distress.

    To analyze the additive effect of supplementing verbal consent with written patient information sheets in optimizing patients' and families' understanding of strabismus surgery. A prospective randomized study was conducted with 28 patients for strabismus surgery randomized into two groups: group 1 with standardized oral informed consent, and group 2 with standardized oral consent and a written information sheet. A confidential questionnaire with 13 questions was completed by patients and families before surgery. A total of 7 adults and 21 children were included in the study. The mean score (number of correct answers) for group 1 was 4.14 ± 1.99; for group 2, 5.79 ± 2.12 (P = 0.044), indicating that patients and families in group 2 understood their strabismus surgery better than those in group 1. Areas needing more emphasis during the consent process were identified, including risk of under- or overcorrection or repeat surgery and use of eyedrops postoperatively. In this study, patient information sheets seemed to help patients and families better understand information about their surgery. Patient recall of information provided is poorly reliable and must be considered in decision making for medicolegal cases.

    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.

    Navigating complex health care systems during the multiple phases of recovery following major trauma entails many challenges for injured patients. Patients' experiences communicating with health professionals are of particular importance in this context. The aim of this study was to explore seriously injured patients' perceptions of communication with and information provided by health professionals in their first 3-years following injury. A qualitative study designed was used, nested within a population-based longitudinal cohort study. Semi-structured telephone interviews were undertaken with 65 major trauma patients, aged 17 years and older at the time of injury, identified through purposive sampling from the Victorian State Trauma Registry. A detailed thematic analysis was undertaken using a framework approach. Many seriously injured patients faced barriers to communication with health professionals in the hospital, rehabilitation and in the community settings. Key themes related to limited contact with health professionals, insufficient information provision, and challenges with information coordination. Communication difficulties were particularly apparent when many health professionals were involved in patient care, or when patients transitioned from hospital to rehabilitation or to the community. Difficulties in patient-health professional engagement compromised communication and exchange of information particularly at transitions of care, e.g., discharge from hospital. Conversely, positive attributes displayed by health professionals such as active discussion, clear language, listening and an empathetic manner, all facilitated effective communication. Most patients preferred communication consistent with patient-centred approaches, and the use of multiple modes to communicate information. The communication and information needs of seriously injured patients were inconsistently met over the course of their recovery continuum. To assist patients along their

    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.

    Little is known about the level of information on implant dentistry in the public. A representative opinion poll on dental implants in the Austrian population was published in 2003 (Clinical Oral Implants Research 14:621-642). Seven years later, the poll was rerun to assess the up-to-date information level and evaluate recent progress and trends in patients' mindset on dental implants. One thousand adults--representative for the Austrian population--were presented with a total of 19 questionnaire items regarding the level and the sources of information about dental implants as well as the subjective and objective need for patient information. Compared with the survey of 2003, the subjective level of patient information about implant dentistry has significantly increased in the Austrian population. The patients' implant awareness rate was 79%. The objective level of general knowledge about dental implants was still all but satisfactory revealing unrealistic patient expectations. Three-quarters trusted their dentists for information about dental implants, while one-quarter turned to the media. The patients' wish for high-quality implant restorations was significantly higher than in 2003, yet the majority felt that only specialists should perform implant dentistry. This representative survey reveals that dentists are still the main source of patient information, but throws doubt on the quality of their public relations work. Dentists must improve communication strategies to provide their patients with comprehensible, legally tenable information on dental implants and bridge information gaps in the future. © 2010 John Wiley & Sons A/S.

    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

    Full Text Available Patient autonomy has been a cornerstone of contemporary clinical ethics since the Nuremberg trial, especially in American school of bioethics. Topic: Patient autonomy has been defined in the Nuremberg Code, and re-defined in the Declaration of Helsinki, Belmont Report and Barcelona Declaration. Founders and followers of the rights-oriented bioethics (for example, Hellegers, Beauchamp and Childers have established and promoted the patient autonomy as the main principle of bio(medical ethics since 1970s. However, there is a lot of controversy surrounding such a principle, especially in vulnerable patients. We aimed at evaluating the real meaning and value of patient autonomy in critical care settings regarding the communication between health workers and their patients and families. Conclusion: Protection of patients autonomy in critically ill is a complex issue. Careful benefit-risk assessment is needed in order to find the most appropriate way of obtaining the informed consent, proxy consent or to omit or delay it.

    We designed and implemented an electronic patient tracking system with improved user authentication and patient selection. We then measured access to clinical information from previous clinical encounters before and after implementation of the system. Clinicians accessed longitudinal information for 16% of patient encounters before, and 40% of patient encounters after the intervention, indicating such a system can improve clinician access to information. We also attempted to evaluate the impact of providing this access on inpatient admissions from the emergency department, by comparing the odds of inpatient admission from an emergency department before and after the improved access was made available. Patients were 24% less likely to be admitted after the implementation of improved access. However, there were many potential confounders, based on the inherent pre-post design of the evaluation. Our experience has strong implications for current health information exchange initiatives.

    Bariatric surgery is an invasive medical treatment for morbid obesity that requires behavioral maintenance for physical success. Patient knowledge, motivation, and adherence are important factors in optimizing results. The purpose of the present study was to identify perceived informational gaps of adolescent and young adult bariatric surgery patients with morbid obesity (body mass index≥40 kg/m(2)). This study took place in a pediatric tertiary care academic medical center. Thirty-one adolescents/young adults who had undergone Roux-en-Y gastric bypass surgery at the authors' institution were recruited to complete questionnaires at their postsurgical visits (≥3 months postsurgery). Seventeen caregivers also participated in this study. The questionnaire used in the present study prompted patients and caregivers to reflect on information they wish they had known before surgery; questionnaire items included multiple choice and open-ended questions. Participants indicated that their informational needs were generally well met before surgery, although there were more needs noted by patients than by caregivers. Adolescent/young adult participants expressed a desire to have had more information about the necessity of taking vitamins daily and about having more gas. An association between informational needs and satisfaction was also found. Qualitative data revealed the importance of conveying cognitive-behavioral aspects of surgery to families (e.g., adherence, motivation). Despite most patients and caregivers being satisfied with the adolescent bariatric surgery program at the authors' institution, informational gaps exist. Teen-friendly ways to disseminate information would be helpful in influencing patients' satisfaction. Copyright © 2016 American Society for Bariatric Surgery. Published by Elsevier Inc.

    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

    This study aims to assess the educational value of YouTube patient testimonial videos in implant dentistry and qualitatively analyse the themes mentioned. Videos were sampled consecutively on YouTube, using the keywords "dental implant patients' testimonials experience," sorted "by relevance." Patient testimonials on dental implant treatment were examined. Inaudible or non-English videos were excluded. Four calibrated investigators scored the videos for educational content, using a matrix derived from the European Association for Osseointegration information booklet, and demographic details were recorded. Data were analysed qualitatively through inductive thematic analysis. A total of 202 videos were analysed (48 exclusions). Inter-examiner reliability was fair to moderate for informative statements and poor to substantial for misleading statements. A mean of 1.8 informative statements were made per video, compared with misleading, 0.5. Many topics were rarely mentioned, with 19/30 themes appearing fewer than 5% of videos. Patients often informed that implants could improve aesthetics and function, but were misleading on aspects of pain control. Some statements may heighten expectations or imply permanency of treatment. Balanced presentation in YouTube testimonials may be limited by bias of clinician-uploaded content. Greater magnitude and breadth of information would improve educational value. Many important parameters of implant therapy were overlooked, whilst information was often potentially misleading. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Studies of online health information seeking are beginning to address a basic question: why do people turn to the Internet? This study draws upon the Uses and Gratifications (U&G) and Media System Dependency (MSD) perspectives to examine in this process the role played by satisfaction with care. The sample comprised 178 cancer listserv users, of whom 35% chose the Internet as their preferred source of health information compared with 19% who named their oncologist. Dissatisfied patients were significantly more likely to rate the Internet as a better source of information than the provider (p = .001). The level of empathy shown by the provider and the quality of time spent with the patient had a significant negative association with choosing the Internet as a preferred source of information, and a significant positive association with choosing the oncologist as an information source. The results from this study emphasize the significance of the patient-provider interaction. Dissatisfied patients' tendency to seek and trust information sources other than their physician also may have implications for compliance with treatment.

A search of English language literature was conducted using PubMed, Google Scholar and EMBASE databases. Many articles have been published which assess the quality of information relating to specific medical conditions. Indicators of quality have been defined in an attempt to predict higher quality health information on the Internet. Quality evaluation tools are scoring systems based on indicators of quality. Established tools such as the HONcode may help patients navigate to more reliable information. Google and Wikipedia are important emerging sources of patient health information. The Internet is crucial for modern dissemination of health information, but it is clear that quality varies significantly between sources. Quality indicators for web-information have been developed but there is no agreed standard yet. We envisage that reliable rating tools, effective search engine ranking and progress in crowd-edited websites will enhance patient access to health information on the Internet.

    Adequate information on oral anticancer agent (OACA) use is an essential element of optimal cancer care. The present study aimed to get insight into the experiences of patients with information on OACA treatment and their characteristics regarding information dissatisfaction. Patients of four Dutch university hospitals using OACA participated in this observational study and completed the Satisfaction with Information about Medicines Scale (SIMS), EORTC Quality of Life Questionnaire-C30, Brief Illness Perception Questionnaire, and Beliefs about Medicines Questionnaire-Specific. Logistic regression analyses were used to determine factors associated with dissatisfaction with information. Patients (n = 208) using capecitabine (35%), lenalidomide (15%), imatinib (14%), temozolomide (12%), sunitinib (11%), thalidomide (5%), dasatinib (4%), erlotinib (2%), and nilotinib (2%) participated. Information on the following SIMS-items was inadequate: how OACA elicit their effect, how long it takes before treatment works, how to conclude that treatment is effective, the risk of side effects and its management, interference with sex life, drowsiness, interference with other medication and alcohol and what to do in case of a missed dose. Younger age, hematological malignancy, dyspnoea, positive perception of consequences of the cancer, low perception of treatment control, and indifferent attitude towards OACA were associated with dissatisfaction with information. In conclusion, a considerable number of patients would have appreciated receiving more information on specific issues relating to the consequences of OACA treatment such as the effects and side effects of OACA and the interference of treatment with various aspects of their daily life. Oncologists, hematologists, lung-oncologists and pharmacists may reconsider the provision of information on OACA treatment. © 2017 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

    A growing number of patients search for health information online. An early investigation of websites about bladder cancer (BCa) revealed mostly incomplete and particularly inaccurate information. We analyzed the quality, readability, and popularity of the most frequented websites on BCa. An Internet search on www.google.com was performed for the term "bladder cancer." After selecting the most frequented websites for patient information, HONcode quality certification, Alexa popularity rank, and readability scores (according to US grade levels) were investigated. A 36-point checklist was used to assess the content according to the EAU guidelines on BCa, which was categorized into seven topics. The popularity of the 49 websites analyzed was average, with a median Alexa popularity rank of 41,698 (interquartile range [IQR] 7-4,671,246). The readability was rated difficult with 11 years of school education needed to understand the information. Thirteen (27%) websites were HONcode certified. Out of 343 topics (seven EAU guideline topics each on 49 websites), 79% were mentioned on the websites. Of these, 10% contained incorrect information, mostly outdated or biased, and 34% contained incomplete information. Publically provided websites mentioned more topics per website (median [IQR] 7 [5.5-7] vs. 5.5 [3.3-7]; p = 0.022) and showed less incorrect information (median [IQR] 0 [0-1] vs. 1 [0-1]; p = 0.039) than physician-provided websites. Our study revealed mostly correct but partially incomplete information on BCa websites for patients. Physicians and public organizations should strive to keep their website information up-to-date and unbiased to optimize patients' health literacy.

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

    Many patients with cancer search out information about their cancer on the internet, thus affecting their relationship with their oncologists. An in-depth analysis of patient-physician communication about information obtained from the internet is currently lacking. We audio-recorded visits of patients with breast cancer and their oncologists where internet information was expected to be discussed. Inductive thematic text analysis was used to identify qualitative themes from these conversations. Twenty-one patients self-reported discussing cancer-related internet information (CRII) with their oncologists; 16 audio recordings contained detectable discussions of CRII and were analyzed. Results indicated that oncologists and patients initiated CRII discussions implicitly and explicitly. Oncologists responded positively to patient-initiated CRII discussions by (1) acknowledging their limited expertise/knowledge, (2) encouraging/approving using the internet as an information resource, (3) providing information/guidance on the proper use of internet searches, (4) discussing the pros and cons of relevant treatment options, or (5) giving information. Finally, patients reacted to the CRII discussions by (1) indicating that they only used reputable sources/websites, (2) asking for further explanation of information, (3) expressing continued concern, or (4) asking for the oncologist's opinion or recommendation. These results indicate that the majority of patients introduce internet information implicitly, in order to guard against any threat to their self-esteem. Physicians, in turn, seem to respond in a supportive fashion to reduce any threat experienced. Future interventions may consider providing prescription-based guidance on how to navigate the internet as a health information resource and to encourage patients to bring these topics up with their oncologist.

    A high-value doctor-patient relationship is based on a set of parameters which include the interpersonal relationship between the patient and the doctor. Based on the Primary Care Assessment Survey model, measures of the interpersonal relationship are associated with communication, interpersonal care, contextual knowledge of the patient, and trust. Despite the proven value of the doctor-patient relationship, current trends indicate that the quality of these relationships is on the decline. The advent of communication and information technologies has greatly affected the way in which health care is delivered and the relationship between doctors and patients. The convergence of communication and information technology with biomedical informatics offers an opportunity to affect the character of the doctor-patient relationship positively. This paper examines the intersection of the key features of the doctor-patient relationship and a variety of Internet-based, clinical, and administrative applications used in dental practice. This paper discusses the role of dental informatics research vis-à-vis the doctor-patient relationship and explores how it may inform the next generation of information technologies used in dental practice.

    The incidence of human papillomavirus (HPV) positive oral squamous cell carcinoma (OSCC) continues to increase over time, challenging healthcare providers to address their patients' HPV-related concerns. This prospective study assessed health literacy, HPV knowledge, utilization and trust in information sources among patients with incident HPV-positive or HPV-negative OSCC diagnosed at the Ohio State University from 2011 to 2015. Health literacy was assessed with a standardized scale. Additional questions evaluated HPV knowledge (including transmission, prevalence, health consequences and treatment), the frequency and type of information sources sought, and trust in those sources. Surveys were collected from 372 OSCC cases (HPV-positive, n=188; HPV-negative, n=184). Despite high mean health literacy scores, only 45.2% of HPV-related knowledge questions were answered correctly. HPV was known to be a sexually transmitted infection and a cause of cervical and anal cancer by 66.0%, 56.5% and 15.2%, respectively. In all domains, cases with HPV-positive OSCC were significantly more informed than HPV-negative cases (for all, pHPV-positive OSCC felt they knew enough to be comfortable discussing HPV with their doctor or sexual partner, respectively. The most frequently used information source was the internet (80.9%), which ranked 8th in trust of 15 possible sources. Although most (95.5%) patients trusted information from their doctors, only 37.9% used doctors as an information source. Doctors are a highly trusted, but infrequent utilized, information source and should facilitate patient access to high-quality HPV information sources. Copyright © 2016. Published by Elsevier Ltd.

    Recent research focused on online health information seeking highlights a heavy reliance on general-purpose search engines. However, current general-purpose search interfaces do not necessarily provide adequate support for non-experts in identifying suitable sources of health information. Popular search engines have recently introduced search tools in their user interfaces for a range of topics. In this work, we explore how such tools can support non-expert, patient-centered health information search. Scoping the current work to medication-related search, we report on findings from a formative study focused on the design of patient-centered, medication-information search tools. Our study included qualitative interviews with patients, family members, and domain experts, as well as observations of their use of Remedy, a technology probe embodying a set of search tools. Post-operative cardiothoracic surgery patients and their visiting family members used the tools to find information about their hospital medications and were interviewed before and after their use. Domain experts conducted similar search tasks and provided qualitative feedback on their preferences and recommendations for designing these tools. Findings from our study suggest the importance of four valuation principles underlying our tools: credibility, readability, consumer perspective, and topical relevance.

    2012-08-01

    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 (www.google.com) 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 (www.discern.org.uk/discern_instrument.php). 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 qualitydentistry.com, 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.

    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.

    In both medical and dental settings, researchers have found that patients do not adequately comprehend the information given during informed consent discussions, especially the less educated, low-income patients. Because of the importance of patient compliance with orthodontic treatment regimens, this study examined patient and parent understanding of the child's Phase I orthodontic treatment in a public dental clinic with ethnically diverse, low-income patients. Interviews were conducted with 29 children (ages 6-12) and their parents or guardians at the orthodontic case presentation appointment. The orthodontist explained the reasons for treatment, the orthodontic procedures to be used, the risks, the alternatives, and patient and parent responsibilities during treatment; the session was audiotaped. Interviews were conducted immediately after this discussion and the results compared with the orthodontists' presentations. In general, both children and parents recalled significantly fewer reasons for treatment (1.10, 1.66, and 2.34 items, respectively), procedures (1.55, 1.59, and 2.45, respectively), risks associated with treatment (0.66, 1.48, and 4.66, respectively), and responsibilities of the child during treatment (2.21, 2.07, and 3.38, respectively) than what the orthodontist had told them. They were also less likely to recall the reasons, procedures, and risks that were most frequently cited by the orthodontist. These findings raise concerns about the effectiveness of current informed consent techniques with public health populations, especially the low recall rates within 30 minutes of the case presentations. Low recall of risks by children and their parents, particularly for critical risks such as relapse, caries, and periodontal problems, raises concerns about treatment compliance, success, and more importantly, the effectiveness of the informed consent process itself. Future research should focus on methods to improve the informed consent process among

    Patients often do not get the information they require from doctors and nurses. To address this problem, interventions directed at patients to help them gather information in their healthcare consultations have been proposed and tested. To assess the effects on patients, clinicians and the healthcare system of interventions which are delivered before consultations, and which have been designed to help patients (and/or their representatives) address their information needs within consultations. We searched: the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library (issue 3 2006); MEDLINE (1966 to September 2006); EMBASE (1980 to September 2006); PsycINFO (1985 to September 2006); and other databases, with no language restriction. We also searched reference lists of articles and related reviews, and handsearched Patient Education and Counseling (1986 to September 2006). Randomised controlled trials of interventions before consultations designed to encourage question asking and information gathering by the patient. Two researchers assessed the search output independently to identify potentially-relevant studies, selected studies for inclusion, and extracted data. We conducted a narrative synthesis of the included trials, and meta-analyses of five outcomes. We identified 33 randomised controlled trials, from 6 countries and in a range of settings. A total of 8244 patients was randomised and entered into studies. The most common interventions were question checklists and patient coaching. Most interventions were delivered immediately before the consultations.Commonly-occurring outcomes were: question asking, patient participation, patient anxiety, knowledge, satisfaction and consultation length. A minority of studies showed positive effects for these outcomes. Meta-analyses, however, showed small and statistically significant increases for question asking (standardised mean difference (SMD) 0.27 (95% confidence interval (CI) 0.19 to 0.36)) and

    Guessing what user may like is now a typical interface for video recommendation. Nowadays, the highly popular user generated content sites provide various sources of information such as tags for recommendation tasks. Motivated by a real world online video recommendation problem, this work targets at the long tail phenomena of user behavior and the sparsity of item features. A personalized compound recommendation framework for online video recommendation called Dirichlet mixture probit model for information scarcity (DPIS) is hence proposed. Assuming that each clicking sample is generated from a representation of user preferences, DPIS models the sample level topic proportions as a multinomial item vector, and utilizes topical clustering on the user part for recommendation through a probit classifier. As demonstrated by the real-world application, the proposed DPIS achieves better performance in accuracy, perplexity as well as diversity in coverage than traditional methods.

    Bonmati, Ester; Bardera, Anton; Boada, Imma

    2017-11-01

    In computational neuroimaging, brain parcellation methods subdivide the brain into individual regions that can be used to build a network to study its structure and function. Using anatomical or functional connectivity, hierarchical clustering methods aim to offer a meaningful parcellation of the brain at each level of granularity. However, some of these methods have been only applied to small regions and strongly depend on the similarity measure used to merge regions. The aim of this work is to present a robust whole-brain hierarchical parcellation that preserves the global structure of the network. Brain regions are modeled as a random walk on the connectome. From this model, a Markov process is derived, where the different nodes represent brain regions and in which the structure can be quantified. Functional or anatomical brain regions are clustered by using an agglomerative information bottleneck method that minimizes the overall loss of information of the structure by using mutual information as a similarity measure. The method is tested with synthetic models, structural and functional human connectomes and is compared with the classic k-means. Results show that the parcellated networks preserve the main properties and are consistent across subjects. This work provides a new framework to study the human connectome using functional or anatomical connectivity at different levels. Copyright © 2017 Elsevier B.V. All rights reserved.

    Patients with orthopedic conditions frequently use the internet to find health information. Patient education that is distributed online may form an easily accessible, time- and cost-effective alternative to education delivered through traditional channels such as one-on-one consultations or booklets. However, no systematic evidence for the comparative effectiveness of Web-based educational interventions exists. The objective of this systematic review was to examine the effects of Web-based patient education interventions for adult orthopedic patients and to compare its effectiveness with generic health information websites and traditional forms of patient education. CINAHL, the Cochrane Library, EMBASE, MEDLINE, PsycINFO, PUBMED, ScienceDirect, Scopus, and Web of Science were searched covering the period from 1995 to 2016. Peer-reviewed English and Dutch studies were included if they delivered patient education via the internet to the adult orthopedic population and assessed its effects in a controlled or observational trial. A total of 10 trials reported in 14 studies involving 4172 patients were identified. Nine trials provided evidence for increased patients' knowledge after Web-based patient education. Seven trials reported increased satisfaction and good evaluations of Web-based patient education. No compelling evidence exists for an effect of Web-based patient education on anxiety, health attitudes and behavior, or clinical outcomes. Web-based patient education may be offered as a time- and cost-effective alternative to current educational interventions when the objective is to improve patients' knowledge and satisfaction. However, these findings may not be representative for the whole orthopedic patient population as most trials included considerably younger, higher-educated, and internet-savvy participants only. ©Tessa Dekkers, Marijke Melles, Bob Sander Groeneveld, Huib de Ridder.

    2011-01-01

    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. Further research is necessary to assess interventions to improve communication prior to surgery.

    In cancer communication, patients and physicians often understand a patient's experience and situation differently. This can negatively impact health outcomes and the physician-patient relationship. To explore how cancer patients' interpretations of the physician's role as information giver affect the communication relationship with the physician and their information-seeking behavior regarding different aspects of their cancer care. Participants completed a semistructured qualitative interview addressing their treatment experience and communication with their physician. Interviews were coded and analyzed using inductive thematic analysis. Ten patients with cancer treated at a regional cancer center in central Illinois participated in the study. Cancer stages I to IV and 4 cancer types were represented. Participants' orientations to the relationship with their physician (and their information-seeking behavior) were classified into 4 general categories: (1) "questioners" have a general mistrust toward their physicians and the information doctors are giving; (2) "the undecided" focuses on physician "fit," often requiring time to step away in order to make decisions and process information; (3) "cross-checkers" are concerned with content of their treatment protocol, often double-checking the treatment plan; and (4) "the experience-oriented" feel a gap between their experience and their physician's experience (and perspective), often seeking information from other survivors. All categories described a perceived lack of adequate exchange of information and the need to seek information outside of the physician-patient relationship to compensate. Participants exhibited different information-seeking behaviors based on how they interpreted the role of their physician as information giver. This affected what kind of information they sought and how they understood the information received, which in turn affected understanding of their broader experience and care.

    This project implemented an integrated patient self-reported screening tool in a patient portal and assessed clinical workflow and user experience in primary care practices. An electronic health risk assessment based on the CMS Annual Wellness Visit (AWV) was developed to integrate self-reported health information into the patient's electronic health record (EHR). Patients enrolled in care coordination tested the implementation. The evaluation plan included quantitative and qualitative measures of patient adoption, provider adoption, workflow impact, financial impact, and technology impact. Seventy-two patients completed the sample AWV, and 80% of the questionnaires had clinical findings that required provider follow-up. Patients expressed satisfaction with the portal, as it enabled them to view their health record and enter information. Implementation did not reduce office staff time. Providers and office staff agreed that an electronic system for adding information to their record would increase patient satisfaction, but they expressed concern with the need to promptly review the information and the time involved to accomplish this prior to an office visit. Despite satisfaction among patients, portal adoption is still low, due to technological limitations and to the lack of adaptability to primary care practice workflow. Notwithstanding those barriers, the use of the portal for completion of repetitive tasks, such as screening tools, should be encouraged. Patients can effectively use portals to complete the patient reported section of the CMS AWV. However, if the information is not completed during the same day of the office visit, the time required to address health findings outside of a regular office visit is uncompensated, and diminished the enthusiasm for this process among primary care practice staff.

    Practitioners treating patients with haematological cancers have extensive clinical information available to give to patients, and patients need to be informed. However, many patients want to be protected from having information that is too detailed or threatening. To illuminate how practitioners can address this dilemma and help patients feel appropriately informed, we explored patients' experience of feeling informed or uninformed. Semi-structured interviews were conducted with 20 patients who had been diagnosed with haematological cancer and had recently received results from clinical investigations or from evaluations of treatment response. Inductive and interpretive analysis of the transcribed audio-recorded interviews drew on constant comparison. Patients described the need for practitioners carefully to manage the information that they provided, and many felt alarmed by information that they did not experience as having been managed for them. A few patients who had difficulty trusting practitioners were not content with the information provided. These findings can be understood using attachment theory, whereby practitioners' careful management of information demonstrates their care for patients, and patients' trust in the practitioner enables them to feel informed. It follows that, when patients do not feel informed, the solution will not necessarily be more information but might be to help patients feel more secure in a caring clinical relationship.

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

    Better diagnosis and early referral due to increased health care coverage have increased the cesarean deliveries at tertiary-care hospitals of India. Improvements in the health care system raise many concerns and need of cross-checking system in place to counter the problems pertaining to patient education and participation of patient. While most of the cesarean sections are done in good faith for the patient, it does not escape the purview of consumer awareness and protection. This cross-sectional study was undertaken at a tertiary level government institution to understand the level of awareness of 220 patients regarding the various aspects of cesarean delivery which are essential for women to know before giving an informed consent. 71 % of the women had knowledge about the indication and need to do cesarean delivery. Of these, only one-third (25 % of total women) were properly explained about procedure and complications. Other demographic and social characteristics were also evaluated. While the health care schemes have had their improved results, the onus lies upon the caregivers to improve and maintain the quality of health care in these tertiary-care government hospitals in proportion to the increase in patient load. The results of this study highlight the need for proper counseling of patients regarding complications of cesarean section. The fact that only 25 % of total cases were explained proper procedure and complication as opposed to 71 % of patients having proper knowledge about the indication of cesarean section points out the lack of information in seemingly "informed" consent. To bring about awareness about the risks and complications of cesarean section, there is a need that patients be counseled during the antenatal visits, specifically when patients visit near term for antenatal check up.

    Recognizing cancer patients' preferences to obtain health information can help improve and reform the methods of communicating and providing proper services and consequently lead to effective patient education. The present cross-sectional study to prioritize the preferences of cancer patients regarding the acquisition of health informationwas conducted on cancer patients referred to hospitals affiliated to Semnan University of Medical Sciences in 2015. An anonymous self-administered questionnaire was developed. In the field of side effects of medications, 50 (46.7%) reported knowing about weight change, in the area of achieving relative health, 62(57.9%) announced awareness about diet, and 45 (42.1%) reported physical complications as a first regarding information needs. In the area of obtaining information, 50 (46.7%) tended to take their information through means outside of the hospital setting. These results can help with design of clinical information systems, as they inform the most relevant and useful coverage designed for cancer patients. Providing useful information through healthcare providers, the media and clinical information systems can act as a major source of social support for cancer patients.

    As health care systems around the world shift toward models that emphasize self-care management, there is increasing pressure for patients to obtain health information online. It is critical that patients are able to identify potential problems with using the Internet to diagnose and treat a health issue and that they feel comfortable communicating with their doctor about the health information they acquire from the Internet. Our aim was to examine patient-identified (1) problems with using the Internet to identify and treat a health issue, (2) barriers to communication with a doctor about online health information seeking, and (3) facilitators of communication with a doctor about patient searches for health information on the Internet. For this qualitative exploratory study, semistructured interviews were conducted with a sample of 56 adults age 50 years old and over. General concerns regarding use of the Internet to diagnose and treat a health issue were examined separately for participants based on whether they had ever discussed health information obtained through the Internet with a doctor. Discussions about barriers to and facilitators of communication about patient searches for health information on the Internet with a doctor were analyzed using thematic analysis. Six higher-level general concerns emerged: (1) limitations in own ability, (2) credibility/limitations of online information, (3) anxiety, (4) time consumption, (5) conflict, and (6) non-physical harm. The most prevalent concern raised by participants who communicated with a doctor about their online health information seeking related to the credibility or limitations in online information. Participants who had never communicated with a doctor about their online health information seeking most commonly reported concerns about non-physical harm. Four barriers to communication emerged: (1) concerns about embarrassment, (2) concerns that the doctor doesn't want to hear about it, (3) belief that there

    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.

    Patients with brain tumours face a number of medical and social challenges. Previous studies have shown that these patients and their relatives need a high level of patient-oriented information and counselling. However, these needs are often underestimated. In this single-centre cross-sectional study, we evaluated, for the first time, the information needs of patients with brain tumours and their relatives depending on diagnosis, age and level of education. The participants were interviewed using pre-specified questionnaires. Answers were evaluated descriptively using standard statistical methods. A total of 888 questionnaires were sent out. The return rate was 50.7%. The majority of patients (nP = 103; 59.9%) and a higher proportion of relatives (nR = 103; 72.5%; p = 0.019) wished to receive a maximum of information. The majority (79.7% of patients; 83.1% of relatives) also stated that they preferred a personal, face-to-face meeting as primary source of information. The need for information increased with education (p = 0.015), and decreased with tumour grade (p = 0.025) and age (p = 0.118). Our data indicate that patients with brain tumours and their relatives have high information needs throughout their disease and continuously require information and counselling. Optimal provision of information is based on personal preferences, which needs to be evaluated appropriately. Patient-oriented information and counselling are parts of a successful communication strategy that can improve cancer care significantly.

    The purpose of this study was to investigate the ability of computed tomography texture analysis (CTTA) to provide additional prognostic information in patients with Hodgkin's lymphoma (HL) and high-grade non-Hodgkin's lymphoma (NHL). This retrospective, pilot-study approved by the IRB comprised 45 lymphoma patients undergoing routine 18F-FDG-PET-CT. Progression-free survival (PFS) was determined from clinical follow-up (mean-duration: 40 months; range: 10-62 months). Non-contrast-enhanced low-dose CT images were submitted to CTTA comprising image filtration to highlight features of different sizes followed by histogram-analysis using kurtosis. Prognostic value of CTTA was compared to PET FDG-uptake value, tumour-stage, tumour-bulk, lymphoma-type, treatment-regime, and interim FDG-PET (iPET) status using Kaplan-Meier analysis. Cox regression analysis determined the independence of significantly prognostic imaging and clinical features. A total of 27 patients had aggressive NHL and 18 had HL. Mean PFS was 48.5 months. There was no significant difference in pre-treatment CTTA between the lymphoma sub-types. Kaplan-Meier analysis found pre-treatment CTTA (medium feature scale, p=0.010) and iPET status (p<0.001) to be significant predictors of PFS. Cox analysis revealed that an interaction between pre-treatment CTTA and iPET status was the only independent predictor of PFS (HR: 25.5, 95% CI: 5.4-120, p<0.001). Specifically, pre-treatment CTTA risk stratified patients with negative iPET. CTTA can potentially provide prognostic information complementary to iPET for patients with HL and aggressive NHL.

    2002-01-01

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

    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.

    With the fast growth of data in multispectral image processing, the traditional storage architecture was challenged. It is currently being replaced by Storage Area Networks (SAN), which makes storage devices externalized from servers. A SAN is a separate network for storage, isolated from the messaging network and optimized for the movement of data between servers and storage devices. Nowadays, most of current SAN use Fibre Channel to move data between servers and storage devices (FC-SAN), but because of the drawbacks of the FC-SAN: for interoperability, lack of skilled professional and management tools, high implementation cost and so on, the development and application of FC-SAN was obstructed. In this paper, we introduce an IP-based Storage Area Networks architecture, which has the good qualities of FC- SAN but overcomes the shortcoming of it. The principle is: use IP technology to move data between servers and storage devices, build a SAN with the IP-based network devices (not the FC-based network device), and through the switch, SAN is attached to the LAN(Local Area Network) through multiple access. Especially, these storage devices are acted as commercial NAS devices and PC.

    Technology could transform routine decision making by anticipating patients' information needs, assessing where patients are with decisions and preferences, personalizing educational experiences, facilitating patient-clinician information exchange, and supporting follow-up. This study evaluated whether patients and clinicians will use such a decision module and its impact on care, using 3 cancer screening decisions as test cases. Twelve practices with 55,453 patients using a patient portal participated in this prospective observational cohort study. Participation was open to patients who might face a cancer screening decision: women aged 40 to 49 who had not had a mammogram in 2 years, men aged 55 to 69 who had not had a prostate-specific antigen test in 2 years, and adults aged 50 to 74 overdue for colorectal cancer screening. Data sources included module responses, electronic health record data, and a postencounter survey. In 1 year, one-fifth of the portal users (11,458 patients) faced a potential cancer screening decision. Among these patients, 20.6% started and 7.9% completed the decision module. Fully 47.2% of module completers shared responses with their clinician. After their next office visit, 57.8% of those surveyed thought their clinician had seen their responses, and many reported the module made their appointment more productive (40.7%), helped engage them in the decision (47.7%), broadened their knowledge (48.1%), and improved communication (37.5%). Many patients face decisions that can be anticipated and proactively facilitated through technology. Although use of technology has the potential to make visits more efficient and effective, cultural, workflow, and technical changes are needed before it could be widely disseminated. © 2017 Annals of Family Medicine, Inc.

    Full Text Available Abstract Background Patient information leaflets (PILs are often used to reinforce and provide further information relating to treatment choices, risks, and alternatives. An assessment of the quality of commonly used orthodontic patient information leaflets is lacking. Methods A cross-sectional assessment of patient information leaflets from two international orthodontic societies was undertaken. The quality of each leaflet was assessed using the DISCERN instrument. The readability of each leaflet was assessed using the Flesch Reading Ease instrument, Flesch-Kincaid Grade Level and Simple Measure of Gobbledygook (SMOG index. Descriptive statistics followed by univariate analysis was conducted. Results Thirty-six patient information leaflets were identified. Reporting of DISCERN instrument items relating to aims, description of sources, details of additional sources, consequences of no treatment, possible treatment options, and support for a shared decision process was of low quality. The overall quality score for the total sample was 44. The median Flesch Reading Ease, Flesch-Kincaid Grade Level, and SMOG index scores were 70 (interquartile range (IQR 53.3–73.9, 7.2 (IQR 6–9.7, and 7.3 (IQR 6.7–9.1, respectively. There was a significant difference between the quality (−8.00, 95 % CI: −14.62, −1.38, p < 0.001, Flesch Reading Ease (−22.30, 95 % CI: −26.77, 17.83, p < 0.001 and the Flesch-Kincaid Grade Level (3.80, 95 % CI: 2.74, 4.86, p < 0.001 scores between the two societies’ PILs. Conclusions In relation to the DISCERN instrument, the quality of orthodontic PILs is deemed of moderate quality. There is a significant difference between the quality scores and the readability of PILs from different societies.

    This paper is a report of a descriptive study of Chinese abdominal surgical patients' and nurses' perceptions of discharge information needs. Discharge from hospital poses a potential threat to surgical patients' lives because they have to cope in daily life with the consequences of the illness and surgery. Recent studies indicate that nurses often underestimate or inappropriately perceive patients' discharge information needs. Few studies have examined the discharge information needs of patients who have undergone abdominal surgery, and research in Asian populations is particularly scarce. A descriptive qualitative study was conducted in 2008. Semi-structured interviews were performed with a convenience sample of 16 patients who had undergone an abdominal surgery and their 16 nurses in a regional general hospital in Hong Kong. Results of content analysis indicated that to both the surgical patients and their nurses, three similar categories of information needs on discharge were health concerns upon discharge, addressing patients' information needs, and obstacles that hindered information seeking. Specific needs related to finance, knowledge of illness, psychological support and role of diet and traditional Chinese medicine perceived as important by the patients were underestimated by the surgical nurses and revealed important issues in providing holistic and culture-specific nursing care for surgical patients upon discharge. Surgical patients' information needs on finance, illness condition, psychological support and cultural practices were found not to be accurately and adequately understood by their nurses. Nurses should give culturally specific and appropriate predischarge education in terms of promotion of recovery from surgery, health maintenance practice and psychological support. © 2010 The Authors.

    2015-09-01

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

  6. Competency Based Hospital Radiopharmacy Training. Additional Information

    International Nuclear Information System (INIS)

    2010-01-01

    Quality management systems in nuclear medicine are vital to a high level of nuclear medicine (NM) practice. Trained and competent staffs are essential for achieving high standards and growth in NM. One of the key bottlenecks for NM is the shortfall in human resources, especially of radiopharmacists. There is an acute shortage in most Member States and in some countries an absence of nationally registered pharmacists with radiopharmacy experience. Most nuclear medicine facilities operate their radiopharmacies (commonly referred to as the hot laboratories) with the support of technologists and radiographers. Recent surveys have found the level of training amongst technologists to be extremely variable. Most had little or no training in hot laboratory practices. The survey also indicated the poor state of hot laboratories in many countries. Basic quality systems in the hot laboratory could be improved significantly with better training. This competency-based education manual is designed with those radiopharmacy practitioners in mind. This competency-based trainer's manual provides trainers in each of the IAEA regions with the essentials of a training programme for all radiopharmacy practitioners. The competency-based training is a two week programme followed up with three months of practice achievements. The syllabus provides a standardized approach to lectures, practical sessions, and interactive workshops focusing on critical aspects of hot laboratory practices. The trainers, with the assistance of this manual, can deliver essential skills, competencies, and underpinning knowledge to operate safely and effectively in their hot laboratory. The course focuses on simple but practical steps that could be undertaken to improve staff performance. In addition, a basic framework of quality management principles related to radiopharmacy practices is also covered. Further, the syllabus can be adapted to the particular needs and characteristics of any training centre, country

  7. Application of a model of social information processing to nursing theory: how nurses respond to patients.

    2008-11-01

    This paper is a report of a study to assess the applicability of a theoretical model of social information processing in expanding a nursing theory addressing how nurses respond to patients. Nursing communication affects patient outcomes such as anxiety, adherence to treatments and satisfaction with care. Orlando's theory of nursing process describes nurses' reactions to patients' behaviour as generating a perception, thought and feeling in the nurse and then action by the nurse. A model of social information processing describes the sequential steps in the cognitive processes used to respond to social cues and may be useful in describing the nursing process. Cognitive interviews were conducted in 2006 with a convenience sample of 5 nurses in the United States of America. The data were interpreted using the Crick and Dodge model of social information processing. Themes arising from cognitive interviews validated concepts of the nursing theory and the constructs of the model of social information processing. The interviews revealed that the support of peers was an additional construct involved in the development of communication skills, creation of a database and enhancement of self-efficacy. Models of social information processing enhance understanding of the process of how nurses respond to patients and further develop nursing theories further. In combination, the theories are useful in developing research into nurse-patient communication. Future research based on the expansion of nursing theory may identify effective and culturally appropriate nurse response patterns to specific patient interactions with implications for nursing care and patient outcomes.

    1995-01-01

    A method and system for processing a set of data from an industrial process and/or a sensor. The method and system can include processing data from either real or calculated data related to an industrial process variable. One of the data sets can be an artificial signal data set generated by an autoregressive moving average technique. After obtaining two data sets associated with one physical variable, a difference function data set is obtained by determining the arithmetic difference between the two pairs of data sets over time. A frequency domain transformation is made of the difference function data set to obtain Fourier modes describing a composite function data set. A residual function data set is obtained by subtracting the composite function data set from the difference function data set and the residual function data set (free of nonwhite noise) is analyzed by a statistical probability ratio test to provide a validated data base.

    The rapid development of the Internet and the increasing interest in Internet-based solutions has promoted the idea of creating Internet-based health information applications. This will force a change in the role of IC cards in healthcare card systems from a data carrier to an access key medium. At the Medical Informatics Department of Kyoto University Hospital we are developing a smart card patient information project where patient databases are accessed via the Internet. Strong end-to-end data encryption is performed via Secure Socket Layers, transparent to transmit patient information. The smart card is playing the crucial role of access key to the database: user authentication is performed internally without ever revealing the actual key. For easy acceptance by healthcare professionals, the user interface is integrated as a plug-in for two familiar Web browsers, Netscape Navigator and MS Internet Explorer.

  10. Why evidence-based medicine failed in patient care and medicine-based evidence will succeed.

    Horwitz, Ralph I; Singer, Burton H

    2017-04-01

    Evidence-based medicine (EBM) has succeeded in strengthening the evidence base for population medicine. Where EBM has failed is in answering the practicing doctor's question of what a likely outcome would be when a given treatment is administered to a particular patient with her own distinctive biological and biographical (life experience) profile. We propose Medicine-based evidence (MBE), based on the profiles of individual patients, as the evidence base for individualized or personalized medicine. MBE will build an archive of patient profiles using data from all study types and data sources, and will include both clinical and socio-behavioral information. The clinician seeking guidance for the management of an individual patient will start with the patient's longitudinal profile and find approximate matches in the archive that describes how similar patients responded to a contemplated treatment and alternative treatments.

    2014-01-01

    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).

    Dupuytren disease is a chronic nonmalign fibroproliferative disorder that causes finger contractures via proliferation of new tissue under the glabrous skin of the hand, resulting in multiple functional limitations for the patient. As many surgical therapy options exist, patients suffering from this condition actively search for information in their environment before consulting a health professional. As little is known about the quality of Web-based patient information, the aim of this study was to conduct its systematic evaluation using a validated tool. A total of 118 websites were included, and qualitative and quantitative assessment was performed using the modified Ensuring Quality Information for Patients (EQIP) tool. This standardized and reproducible tool consists of 36 items to assess available information in three categories: contents, identification, and structure data. Scientific data with restricted access, duplicates, and irrelevant websites were not included. Only 32 websites addressed more than 19 items, and the scores did not significantly differ among the website developers. The median number of items from the EQIP tool was 16, with the top websites addressing 28 out of 36 items. The quality of the newly developed websites did not increase with passing time. This study revealed several shortcomings in the quality of Web-based information available for patients suffering from Dupuytren disease. In the world of continuously growing and instantly available Web-based information, it is the health providers' negligence of the last two decades that there are very few good quality, informative, and educative websites that could be recommended to patients. ©Grzegorz Zuk, Katharina B Reinisch, Dimitri A Raptis, Sonia Fertsch, Merlin Guggenheim, Adrian F Palma.

    Informal patient payments for healthcare are common in the Western Balkans, negatively affecting public health and healthcare. To identify literature from the Western Balkans on what is known about informal patient payments and bought and brought goods, to examine their effects on healthcare and to determine what actions can be taken to tackle these payments. After conducting a scoping review that involved searching websites and databases and filtering with eligibility criteria and quality assessment tools, 24 relevant studies were revealed. The data were synthesized using a narrative approach that identified key concepts, types of evidence, and research gaps. The number of studies of informal patient payments increased between 2002 and 2015, but evidence regarding the issues of concern is scattered across various countries. Research has reported incidents of informal patient payments on a wide scale and has described various patterns and characteristics of these payments. Although these payments have typically been small - particularly to providers in common areas of specialized medicine - evidence regarding bought and brought goods remains limited, indicating that such practices are likely even more common, of greater magnitude and perhaps more problematic than informal patient payments. Only scant research has examined the measures that are used to tackle informal patient payments. The evidence indicates that legalizing informal patient payments, introducing performance-based payment systems, strengthening reporting, changing mentalities and involving the media and the European Union (EU) or religious organizations in anti-corruption campaigns are understood as some of the possible remedies that might help reduce informal patient payments. Despite comprehensive evidence regarding informal patient payments, data remain scattered and contradictory, implying that informal patient payments are a complex phenomenon. Additionally, the data on bought and brought goods

    Little is known about patients' online health information seeking after a primary care or specialist medical visit. To examine predictors of patients' post-visit online health information seeking, reasons for seeking information and information sources used. Survey of online support group members (N = 311) with a recent medical visit. Measures included eHealth literacy, patient-centred communication (PCC), post-visit changes in worry, online health information seeking and reasons for seeking information. Analyses were based on descriptive statistics and logistic regression. Eighty per cent of patients went online post-visit. The most common source used was others' forum posts (91%). The most common reason was curiosity (68%). Dissatisfaction with the physician's performance motivated information seeking for 40% of respondents. In a multivariate analysis, post-visit online health information seeking was highest among patients who were more eHealth literate [odds ratio (OR) = 1.73 (95% confidence interval (CI): 1.11, 2.71), P = 0.016], gave lower PCC ratings to their providers [OR = 0.45 (0.22, 0.90), P = 0.024] and experienced increased worry due to the visit [OR = 5.19 (1.36, 19.82), P = 0.016]. eHealth literate patients made greater use of specialized medical information (e.g. online medical journal articles) than less literate patients. Primary care physicians were rated as more patient centred than specialists. Visit-induced worry led to greater use of interpersonal channels (e.g. e-mailing other forum members). Patients who saw their doctor as less patient-centred were more likely to go online due to dissatisfaction with doctor performance. Online support forum members often turn to the Internet for health information following their medical visits. Their information seeking is shaped by patient, relational and visit factors. © The Author 2014. Published by Oxford University Press. All rights reserved.

    With the rapid development of the Internet, digitization and electronic orientation are required in various applications of our daily life. For e-medicine, establishing Electronic patient records (EPRs) for all the patients has become the top issue during the last decade. Simultaneously, constructing an integrated EPR information system of all the patients is beneficial because it can provide medical institutions and the academia with most of the patients' information in details for them to make correct decisions and clinical decisions, to maintain and analyze patients' health. Also beneficial to doctors and scholars, the EPR system can give them record linkage for researches, payment audits, or other services bound to be developed and integrated into medicine. To tackle the illegal access and to prevent the information from theft during transmission over the insecure Internet, we propose a password-based user authentication scheme suitable for information integration.

    Full Text Available Devising an information architecture system that enables an organization to centralize information regarding its operational, managerial and strategic performance is one of the challenges currently facing information technology. The present study aimed to analyze an information architecture system developed using Business Intelligence (BI technology. The analysis was performed based on a questionnaire enquiring as to whether the information needs of executives were met during the process. A theoretical framework was applied consisting of information architecture and BI technology, using a case study methodology. Results indicated that the transaction processing systems studied did not meet the information needs of company executives. Information architecture using data warehousing, online analytical processing (OLAP tools and data mining may provide a more agile means of meeting these needs. However, some items must be included and others modified, in addition to improving the culture of information use by company executives.

    The effective treatment of schizophrenia requires continuous antipsychotic maintenance therapy. However, poor persistence with treatment is common among patients with schizophrenia. The objective of this study was to compare persistence and hospitalization rates among patients with schizophrenia treated with long-acting injectable (LAI) antipsychotics (i.e. paliperidone palmitate and risperidone) and enrolled in a patient information program (program cohort) with patients treated with oral antipsychotics (OAs) who were not enrolled in a patient information program (nonprogram cohort). Using a quasi-experimental design, data from chart reviews (for program patients) and Medicaid claims (for nonprogram patients) was analyzed. Patients were eligible if they had ≥12 months of pre-index data, ≥6 months of post-index data, and no hospitalization at index. Persistence and hospitalization rates were assessed at 6 months post-index. Propensity score matching was used to control for observed differences in demographics and baseline clinical characteristics. Odds ratios (ORs) were calculated using generalized estimating equation models and adjusted for matched pairs and propensity score. A total of 102 program patients were matched to 408 nonprogram patients with similar baseline characteristics. Adjusted ORs indicated that the persistence rate at 6 months was significantly higher for the program cohort (88.2%) versus the nonprogram cohort (43.9%; OR: 9.70; P program cohort (14.7%) was significantly lower versus the nonprogram cohort after adjustments (22.5%; OR: 0.55; P = 0.0321). The data for the program and nonprogram patients were from two different and independent data sources (healthcare claims and chart reviews, respectively). Results were based on a relatively small number of program LAI patients. Program patients treated with LAI antipsychotics had higher persistence rates and significantly lower adjusted hospitalization rates compared with nonprogram

    2016-11-29

    People with disabilities use various assistance devices to improve their capacity to lead independent and fulfilling lives. Service dogs can be crucial lifesaving companions for their owners. As the use of service dogs increases, nurses are more likely to encounter them in healthcare settings. Service dogs are often confused with therapy or emotional support dogs. While some of their roles overlap, service dogs have distinct protection under the American Disabilities Act (ADA). Knowing the laws and proper procedures regarding service dogs strengthens the abilities of healthcare providers to deliver holistic, patient-centered care. This article provides background information about use of dogs, and discusses benefits to patients and access challenges for providers. The author reviews ADA laws applicable to service dog use and potential challenges and risks in acute care settings. The role of the healthcare professional is illustrated with an exemplar, along with recommendations for future research and nursing implications related to care of patients with service dogs.

    2011-01-01

    Information and communication technologies have long been acknowledged to support information sharing along the whole chain of care, from the clinic to the homes of patients and their relatives. Thus they are increasingly being considered for improving the delivery of health care services also in light of clinical and technological achievements that propose new treatments requiring a tighter interaction among patients and physicians. The multiagent paradigm has been utilized within an architecture for delivering telemedicine services to chronic outpatients at their domiciles and enforcing cooperation among patients, caregivers, and different members of the health care staff. The architecture sees each communication device such as a palmtop, smart phone, or personal digital assistant as a separate agent upon which different services are deployed, including telemetry, reminders, notifications, and alarms. Decoupling services from agents account for a highly configurable environment applicable to almost any context that can be customized as needed. The architecture has been used for designing and implementing a prototypical software infrastructure, called LifePhone, that runs on several communication devices. A basic set of services has been devised with which we were able to configure two different applications that address long-term and short-term monitoring scenarios for diabetes patients. The long-term scenario encompasses telemetry and reminder services for patients undergoing peritoneal dialysis, which is a treatment for chronic renal failure, a diabetes complication. The short-term scenario incorporates telemetry and remote alarms and is applicable for training patients to use an artificial pancreas. Our experiments proved that an infrastructure such as LifePhone can be used successfully for bridging the interaction gap that exists among all the components of a health care delivery process, improving the quality of service and possibly reducing the overall

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

    As the basic mean to obtain the information of the targets network, network scanning is often used to discover the security risks and vulnerabilities existing on the network. However, with the development of network technology, the scale of network is more and more large, and the network scanning efficiency put forward higher requirements. In this paper, the concept of network scanning information granularity is proposed, and the design method of network scanning strategy based on information granularity is proposed. Based on single information granularity and hybrid information granularity, four network scanning strategies were designed and verified experimentally. Experiments show that the network scanning strategies based on hybrid information granularity can improve the efficiency of network scanning.

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

    Full Text Available In this paper we examine the domain of information search and propose a "goal-based" approach to study search strategy. We describe "goal-based information search" using a framework of Knowledge Discovery. We identify two Information Retrieval (IR goals using the constructs of Knowledge Acquisition (KA and Knowledge Explanation (KE. We classify these constructs into two specific information problems: An exploration-exploitation problem and an implicit-explicit problem. Our proposed framework is an extension of prior work in this domain, applying an IR Process Model originally developed for Legal-IR and adapted to Medical-IR. The approach in this paper is guided by the recent ACM-SIG Medical Information Retrieval (MedIR Workshop definition: "methodologies and technologies that seek to improve access to medical information archives via a process of information retrieval."

    The provision of information is now considered a major area in pharmacist-patient interactions. However, few reports have simultaneously evaluated patient and pharmacist perceptions with regard to the pharmacist's information provision. The aims were to clarify the perceptions of pharmacists and patients regarding information provision and the level of influence of those perceptions on patient satisfaction. A cross-sectional survey with respect to information provision was conducted for patients and pharmacists in community pharmacies in Fukuoka Prefecture, Japan. In total, 407 patient-pharmacist pairs were included in a t-test and multilevel analysis. The levels of patient perception regarding information provision were significantly higher than the levels of pharmacist perception in all variables. The pharmacists' perceived level of information provision concerning medication effects had a negative and significant association with patient satisfaction, while the patients' perceived level of information provision by the pharmacist had a positive and significant association with patient satisfaction. Higher patient expectations regarding the level of information provision concerning medication side effects and older age of the pharmacist were adversely related to patient satisfaction. Both pharmacist and patient perceptions of the information provision by pharmacists personalized to the patient had positive associations with patient satisfaction. Pharmacist perceptions related to the information provision were not associated with patient satisfaction. The present study highlights accurate information provision, building good patient-pharmacist relationships, and improving pharmaceutical care in community pharmacy settings. © 2015 John Wiley & Sons, Ltd.

    Motivated by the recent proposed models of the information engine [Proc. Natl. Acad. Sci. USA 109, 11641 (2012), 10.1073/pnas.1204263109] and the information refrigerator [Phys. Rev. Lett. 111, 030602 (2013), 10.1103/PhysRevLett.111.030602], we propose a minimal model of the information pump and the information eraser based on enzyme kinetics. This device can either pump molecules against the chemical potential gradient by consuming the information to be encoded in the bit stream or (partially) erase the information initially encoded in the bit stream by consuming the Gibbs free energy. The dynamics of this model is solved exactly, and the "phase diagram" of the operation regimes is determined. The efficiency and the power of the information machine is analyzed. The validity of the second law of thermodynamics within our model is clarified. Our model offers a simple paradigm for the investigating of the thermodynamics of information processing involving the chemical potential in small systems.

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

    This study investigate the effect of health information technology (IT) expenditure on individual patient-level cost using California Office of Statewide Health Planning and Development (OSHPD) data obtained from 2000 to 2007. We used a traditional cost function and applied hospital fixed effect and clustered error within hospitals. We found that a quadratic function of IT expenditure best fit the data. The quadratic function in IT expenditure predicts a decrease in cost of up to US$1,550 of IT labor per bed, US$27,909 of IT capital per bed, and US$28,695 of all IT expenditure per bed. Moreover, we found that IT expenditure reduced costs more quickly in medical conditions than surgical diseases. Interest in health IT is increasing more than ever before. Many studies examined the effect of health IT on hospital level cost. However, there have been few studies to examine the relationship between health IT expenditure and individual patient-level cost. We found that IT expenditure was associated with patient cost. In particular, we found a quadratic relationship between IT expenditure and patient-level cost. In other word, patient-level cost is non-linearly (or a polynomial of second-order degree) related to IT expenditure.

    To identify cancer patient and relatives beliefs, information needs, information-seeking behavior and information sources about cancer and treatment. This research was conducted at two hospitals of a university. Data was collected via questionnaires and the Turkish version of the Miller Behavioral Style Scale (MBSS) to assess information-seeking behavior. The sample included 82 patients and 54 relatives. Patients were receiving treatment mostly for breast, gynecologic, lung cancer and leukemia/ lymphoma. All of them indicated that they want to be informed by a doctor about their diagnosis and treatment first. Other information sources were internet, media and nurses. The majority of the patients and half of their relatives agreed that "cancer is curable and preventable disease". Only 2.5% of patients agreed with the statement "I don't want to get information about disease which disturbs me". According the data obtained from MBSS; the mean patients MBSS score (6.41±3.2) was higher than their relatives (5.46±3.1). Respondents with higher education and younger age indicated more information-seeking behavior. Patients and their relatives differ in some of their information-seeking behavior. Patients beliefs and their strategies for coping with their illness can constrain their wish for information and their efforts to obtain it. Healthcare professionals need to assess and be sensitive to the information-seeking behavior of cancer patients and their relatives.

    Full Text Available Researchers who use science and technology information were found to ask an information service in which they can excerpt the contents they needed, rather than using the information at article level. In this study, we micronized the contents of scholarly articles into text, image, and table and then constructed a micro-content DB to design a new information system prototype based on this micro-content. After designing the prototype, we performed usability test for this prototype so as to confirm the usefulness of the system prototype. We expect that the outcome of this study will fulfill the segmented and diversified information need of researchers.

    Hospitals are implementing a risk management system to avoid patient or surgery mix-ups. The trend is to use preoperative checklists. This work deals specifically with a type of patient identification, which is realized by storing patient data on a patient-fixed medium. In 127 ENT surgeries data relevant for patient identification were encrypted in a 2D-QR-Code. The code, as a separate document coming with the patient chart or as a patient wristband, has been decrypted in the OR and the patient data were presented visible for all persons. The decoding time, the compliance of the patient data, as well as the duration of the patient identification was compared with the traditional patient identification by inspection of the patient chart. A total of 125 QR codes were read. The time for the decrypting of QR-Code was 5.6 s, the time for the screen view for patient identification was 7.9 s, and for a comparison group of 75 operations traditional patient identification was 27.3 s. Overall, there were 6 relevant information errors in the two parts of the experiment. This represents a ratio of 0.6% for 8 relevant classes per each encrypted QR code. This work allows a cost effective way to technically support patient identification based on electronic patient data. It was shown that the use in the clinical routine is possible. The disadvantage is a potential misinformation from incorrect or missing information in the HIS, or due to changes of the data after the code was created. The QR-code-based patient tracking is seen as a useful complement to the already widely used identification wristband. © Georg Thieme Verlag KG Stuttgart · New York.

    The Health Risk Reminders and Surveillance (HRRS) system was designed to deliver critical abnormal test results of severely ill patients from Laboratory, Radiology, and Pathology departments to physicians within 5 min using cell phone text messages. This paper explores the success of the HRRS system. This study employed an augmented version of the DeLone and McLean IS success model. Seven variables (system quality, information quality, system use, user satisfaction, mobile healthcare anxiety, impact on the individual and impact on the organization) were used to evaluate the success of the HRRS system. The interrelationships between the seven variables were hypothesized and the hypotheses were empirically tested. The results indicate that the information quality of the HRRS system is positively associated with both system use and user satisfaction. In addition, system use is positively associated with user satisfaction, which is also positively associated with mobile healthcare anxiety. Moreover, results indicate that impact on the individual is positively associated with both user satisfaction and mobile healthcare anxiety. Finally, the impact of the organization is positively associated with impact on the individual. The results of the study provide an expanded understanding of the factors that contribute to mobile patient safety information system (IS) success. Implications of the relationship between system use and physician mobile healthcare anxiety are discussed.

    Current information technology is centered on the internet and changes our daily working pattern, particularly with multimedia information. Rapid development of information processing hardware and software has enabled us to deploy multimedia information management system of low hit counts and small amount of information volume on the desktop computer and publish multimedia information directly to the workgroup intranet with no particular additional hardware and software. Success of the timely development of the information system depends on the adoption of the proper direction and scale of information technology. The nuclear control mainly consists of safeguards, physical protection and export/import control. This paper provides an investigation on the application of openly available multiple media information to the nuclear control information management system. Information system with spatial map, image data including satellite imagery, audio, and video makes users easy to understand the current status and communicate each other easily. The Digital Terrain Elevation Data (DTED) Level 0 of the U.S. NIMA (National Imagery and Mapping Agency) is used as a base map. The multimedia information system is mainly built with Microsoft PowerPoint 2000 and Office Web component. A database with the second normal form was applied to the Office Web component. The importance of the information security was stressed

    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.

    Full Text Available Introduction: To ensure continuity of care, it is important to effectively communicate the health status of older patients who are transferred between health care organizations. The objectives of this study were to: (1 evaluate the prevalence of nursing transfer documents, and (2 identify patient and transfer characteristics associated with the presence of nursing transfer documents for older patients transferred from home care to hospital and back to home care again after hospitalization. Methods: Nursing documents were reviewed from a total of 102 records of older inpatients admitted from home care to medical wards at a local hospital in central Norway and later discharged home. Frequencies were used to describe patient and transfer characteristics, and the prevalence of transfer documents. Pearson's chi-square test and logistic regression were used to identify possible associations between patient and transfer characteristics and the presence of nursing transfer documents. Results: While nursing admission notes were present in 1% of the patient transfers from home care to the hospital, 69% of patient discharges from the hospital to home care were accompanied by nursing discharge notes. Patient and transfer characteristics associated with the presence of a nursing discharge note were age, gender, medical department facility, and length of hospital stay. Conclusions: The low prevalence of nursing transfer documents constitutes a challenge to the continuity of care for hospitalized home care patients. Patient and transfer characteristics may impact the nurses' propensity to exchange patient information. These findings emphasize the need for nurses and managers to improve the exchange of written information. While nurses must strive to transfer accurate patient information at the right place and at the right time, the managers must facilitate this by providing appropriate guidelines and standards, as well as adequate personnel and resources.

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

    2003-01-01

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

  4. Transforming Patient-Centered Care: Development of the Evidence Informed Decision Making through Engagement Model.

    2015-01-01

    In response to the passage of the Affordable Care Act in the United States, clinicians and researchers are critically evaluating methods to engage patients in implementing evidence-based care to improve health outcomes. However, most models on implementation only target clinicians or health systems as the adopters of evidence. Patients are largely ignored in these models. A new implementation model that captures the complex but important role of patients in the uptake of evidence may be a critical missing link. Through a process of theory evaluation and development, we explore patient-centered concepts (patient activation and shared decision making) within an implementation model by mapping qualitative data from an elective induction of labor study to assess the model's ability to capture these key concepts. The process demonstrated that a new, patient-centered model for implementation is needed. In response, the Evidence Informed Decision Making through Engagement Model is presented. We conclude that, by fully integrating women into an implementation model, outcomes that are important to both the clinician and patient will improve. In the interest of providing evidence-based care to women during pregnancy and childbirth, it is essential that care is patient centered. The inclusion of concepts discussed in this article has the potential to extend beyond maternity care and influence other clinical areas. Utilizing the newly developed Evidence Informed Decision Making through Engagement Model provides a framework for utilizing evidence and translating it into practice while acknowledging the important role that women have in the process.

    To evaluate the effect of an intelligent Internet-based information system upon optimising the management of patients diagnosed with type 2 diabetes mellitus (T2DM). In 2015, a T2DM information system was introduced to optimise the management of T2DM patients for 1 year in Fangzhuang community of Beijing, China. A total of 602 T2DM patients who were registered in the health service centre of Fangzhuang community were enrolled based on an isometric sampling technique. The data from 587 patients were used in the final analysis. The intervention effect was subsequently assessed by statistically comparing multiple parameters, such as the prevalence of glycaemic control, standard health management and annual outpatient consultation visits per person, before and after the implementation of the T2DM information system. In 2015, a total of 1668 T2DM patients were newly registered in Fangzhuang community. The glycaemic control rate was calculated as 37.65% in 2014 and significantly elevated up to 62.35% in 2015 ( p information system, the rate of standard health management was increased from 48.04% to 85.01% ( p information system optimised the management of T2DM patients in Fangzhuang community and decreased the outpatient numbers in both community and general hospitals, which played a positive role in assisting T2DM patients and their healthcare providers to better manage this chronic illness.

  7. BIM-Based Construction Information Management Framework for Site Information Management

    2018-01-01

    Full Text Available Projects in the construction industry are becoming increasingly large and complex, with construction technologies, methods, and the like developing rapidly. Various different types of information are generated by construction projects. Especially, a construction phase requires the input of many resources and generates a diverse set of information. While a variety of IT techniques are being deployed for information management during the construction phase, measures to create databases of such information and to link these various different types of information together are still insufficient. As such, this study aims to suggest a construction information database system based on BIM technology to enable the comprehensive management of site information generated during the construction phase. This study analyzed the information generated from construction sites and proposed a categorization system for structuring the generated information, along with a database model for storing such structured information. Through such efforts, it was confirmed that such a database system can be used for accumulating and using construction information; it is believed that, in the future, the continual accumulation and management of construction information will allow for corporate-level accumulation of knowledge as opposed to the individual accumulation of know-how.

    Despite the benefits of advance directives (AD) to patients and care providers, they are often not completed due to lack of patient awareness. The purpose of the current article is to advocate for creation and use of an innovative information visualization (infovisual) as a health communication tool aimed at improving AD dissemination and engagement. The infovisual would promote AD awareness by encouraging patients to learn about their options and inspire contemplation and conversation regarding their end-of-life (EOL) journey. An infovisual may be able to communicate insights that are often communicated in words, but are much more powerfully communicated by example. Furthermore, an infovisual could facilitate vivid understanding of options and inspire the beginning of often difficult conversations among care providers, patients, and loved ones. It may also save clinicians time, as care providers may be able to spend less time explaining details of EOL care options. Use of an infovisual could assist in ensuring a well-planned EOL journey.

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

    Patients are increasingly turning to the internet to seek reliable sources of health information and desire guidance in assessing the quality of information as healthcare becomes progressively more complex. Pituitary adenomas are a rare, diverse group of tumors associated with increased mortality and morbidity whose management requires a multidisciplinary approach. As such, patients with this disorder are often searching for additional sources of healthcare information. We undertook a study to assess the quality of information available on the internet for patients with pituitary adenoma. After exclusion, 42 websites were identified based on a search engine query with various search terms. Each website was assessed in triplicate: once by a health professional, once by a simulated patient, and once by a patient who had a pituitary adenoma and underwent medical and surgical treatment. The assessment tools included a content-specific questionnaire, the DISCERN tool, and the Ensuring Quality Information for Patients tool. The readability of the information was assessed with the Flesch-Kincaid grade level. We found that the overall quality of information on pituitary adenoma on the internet was variable and written at a high grade level. Correlation between the different assessors was poor, indicating that there may be differences in how healthcare professionals and patients view healthcare information. Our findings highlight the importance of assessment of the health information by groups of the intended user to ensure the needs of that population are met.

    Despite the demographically driven rapid growth of the number of persons with dementia, in Germany a website is lacking that provides evidence based information about the disease, its burden and therapeutic options to family and professional carers as well as physicians. A website was developed with the objective to give free access to evidence based information concerning the disease and care for patients with dementia. In order to meet the expectations of the user groups an analysis of information needs was performed with 80 physicians, 163 professional carers and 104 family carers. All user groups rated information on symptoms, course and treatment of dementia and support for family carers as important topics. Group differences were found for the need to be informed on financial support, daily care and interaction with patients. The contents of the website will be accommodated to the specific needs of the user groups. © Georg Thieme Verlag KG Stuttgart · New York.

    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. 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. 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. 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. 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, it is necessary to test its effects on key outcomes

    Nuclear medicine procedures use radiopharmaceuticals, which produce radiation and potential adverse reactions, albeit at a low rate. It is the patient's ethical, legal, and medical right to be informed of the potential side effects of procedures applied to them. Our purpose was to determine the effect of providing information about intravenous radiopharmaceutical administration on the anxiety level of patients who request more information. This study was completed in two separate Nuclear Medicine Departments. The study included 620 (247 M, 373 F) patients who had been referred for myocardial perfusion, bone, dynamic renal, and thyroid scintigraphic examinations. The patients were divided into two groups according to whether they requested more information or not. Group 1 consisted of 388 patients who wanted to receive more information about the procedure, while Group 2 consisted of 232 patients who did not request additional information. The State-Trait Anxiety Inventory (STAI-S and STAI-T) was used to determine a patient's anxiety level. After simple information was given, state and trait anxiety levels were measured in both groups. We gave detailed information to the patients in Group 1 and then measured state anxiety again. Detailed information included an explanation of the radiopharmaceutical risk and probable side effects due to the scan procedure. There was no statistical difference between Groups 1 and 2 in STAI-T or STAI-S scores after simple information was given (p=0.741 and p=0.945, respectively). The mean value of STAI-S score was increased after the provision of detailed information and there was a statistically significant difference between after simple information STAI-S and after detailed information STAI-S (p<0.001). The STAI-S score was increased in 246 patients and decreased in 110 patients after detailed information, while there was no change in 32 patients. After detailed information, the greatest increase in STAI-S score was seen in the

    This paper discussed the presentation of information in computer-based control rooms. Issues associated with the typical displays currently in use are discussed. It is concluded that these displays should be augmented with new displays designed to better meet the information needs of plant personnel and to minimize the need for interface management tasks (the activities personnel have to do to access and organize the information they need). Several approaches to information design are discussed, specifically addressing: (1) monitoring, detection, and situation assessment; (2) routine task performance; and (3) teamwork, crew coordination, collaborative work

    To identify the variables affecting patients' online health information-seeking behaviours by examining the relationships between patient participation in their healthcare and online health information-seeking behaviours. A cross-sectional survey of Italian chronic patients (N=352) was conducted on patient's online health information-seeking behaviours and patient participation-related variables. Structural equation modeling analysis was conducted to test the hypothesis. This study showed how the healthcare professionals' ability to support chronic patients' autonomy affect patients' participation in their healthcare and patient's online health information-seeking behaviours. However, results do not confirm that the frequency of patients' online health-information seeking behavior has an impact on their adherence to medical prescriptions. Assuming a psychosocial perspective, we have discussed how patients' engagement - conceived as the level of their emotional elaboration of the health condition - affects the patients' ability to search for and manage online health information. To improve the effectiveness of patients' online health information-seeking behaviours and to enhance the effectiveness of technological interventions in this field, healthcare providers should target assessing and improving patient engagement and patient empowerment in their healthcare. It is important that health professionals acknowledge patients' online health information-seeking behaviours that they discuss the information offered by patients and guide them to reliable and accurate web sources.

    2012-11-01

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

  6. METHODOLOGICAL APPROACH TO ANALYSIS AND EVALUATION OF INFORMATION PROTECTION IN INFORMATION SYSTEMS BASED ON VULNERABILITY DANGER

    Directory of Open Access Journals (Sweden)

    Y. M. Krotiuk

    2008-01-01

    Full Text Available The paper considers a methodological approach to an analysis and estimation of information security in the information systems which is based on the analysis of vulnerabilities and an extent of their hazard. By vulnerability hazard it is meant a complexity of its operation as a part of an information system. The required and sufficient vulnerability operational conditions  have  been  determined in the paper. The paper proposes a generalized model for attack realization which is used as a basis for construction of an attack realization model for an operation of a particular vulnerability. A criterion for estimation of information protection in the information systems which is based on the estimation of vulnerability hazard is formulated in the paper. The proposed approach allows to obtain a quantitative estimation of the information system security on the basis of the proposed schemes on realization of typical attacks for the distinguished classes of vulnerabilities.The methodical approach is used for choosing variants to be applied for realization of protection mechanisms in the information systems as well as for estimation of information safety in the operating information systems.

    Diabetes is a disease that involves alterations at multiple biological levels, ranging from intracellular signalling to organ processes. Since glucose homeostasis is the consequence of complex interactions that involve a number of factors, the control of diabetes should be based on a multilevel analysis. In this paper, a novel approach to design of closed-loop glucose controllers based on multilevel models is presented. A control scheme is proposed based on combining a pharmacokinetic/pharmacodynamic model with an insulin signal transduction model for type 1 diabetes mellitus patients. Based on this, an insulin feedback control schemes is designed. Two main advantages of explicitly utilizing information at the intracellular level were obtained. First, significant reduction of hypoglycaemic risk by reducing the undershoot in glucose levels in response to added insulin. Second, robust performance for inter-patient changes, demonstrated through application of the multilevel control strategy to a well established in silico population of diabetic patients.

    The continuously increased mobility of patients and doctors, in conjunction with the existence of medical groups consisting of private doctors, general practitioners, hospitals, medical centers, and insurance companies, pose significant difficulties on the management of patients' medical data. Inevitably this affects the quality of the health care services provided. The evolving smart card technology can be utilized for the implementation of a secure portable electronic medical record, carried by the patient herself/himself. In addition to the medical data, insurance information can be stored in the smart card thus facilitating the creation of an "intelligent system" supporting the efficient management of patient's data. In this paper we present the main architectural and functional characteristics of such a system. We also highlight how the security features offered by smart cards can be exploited in order to ensure confidentiality and integrity of the medical data stored in the patient cards.

    Literature clearly demonstrates that there has been a large increase in the time devoted to teaching oral communication skills within medical curricula worldwide. In contrast, the ability to communicate with patients through written means does not appear to be a feature in many programmes, despite its fundamental importance in creating understanding of medicine within the general population. This article investigates one way patient-centered written communication has been integrated into part of the early training years of medical students using anatomically related material as a focus. Following a series of interactive seminars and debates as part of a student-selected component, students were asked to prepare a patient-focused information leaflet on a particular birth defect. The leaflets included aspects of anatomy and embryology as well as causes of the birth defect, signs and symptoms, treatments, outlook, and support mechanisms. Evaluation of the leaflets using set marking criteria and readability indexes showed that students had successfully targeted the chosen audiences. Feedback showed that the component was rated highly by the students in terms of quality, usefulness, and interest. Students viewed sessions as an excellent forum for appreciating the importance of and developing their own effective written communication skills. It is hoped that such developments will enhance the capacity of all potential doctors to communicate more effectively with patients and colleagues in both the written and spoken form.

    Informed consent (IC) is a legally enforceable right in South Africa based on constitutionally protected rights to bodily integrity and well-being. In terms of the law, patients cannot be involved in medical treatment or research without IC. Healthcare providers must inform patients about diagnosis, risks, benefits, treatment options, and right of refusal in a language patients understand based their literacy level. This study reports an empirical study on patients' perceptions of IC as practiced by doctors and nurses in South Africa. A cross-sectional study, using a bilingual semi-structured questionnaire was conducted among patients attending randomly selected public hospitals in eThekwini Metropolitan Municipality (Durban), KwaZulu-Natal province. Competent patients or legal surrogates were eligible for inclusion. IC was obtained from all participants. Four hundred and four participants completed questionnaires of which 68% were female. The median age of participants was 35 years (range 11-91 years). Most respondents spoke IsiZulu (55%), were single (56%), unemployed (66%), and with secondary school education (69%). Patients were generally informed about the diagnosis (81%), risks (57%), and benefits of treatment (61%). Few were informed about treatment options (41%), recommended treatment (28%), and right of refusal (25%). IC was obtained verbally in 73% of cases. Patients favored disclosure of all material risks (78%) and few consulted surrogates before decision-making (76%). There was an association between participant's age and knowledge of the age of consent (P = 0.005). Most patients were satisfied with information disclosed (91%) and did not feel coerced. Some were afraid to ask questions for fear of losing free treatment (8%). This study reveals that South African patients are aware of the right to IC, but many were vulnerable due to indigence. Barriers to IC include poverty, language, and low educational level. South African patients prefer disclosure

    The objectives of this analysis were to examine how patients' dependence on others relates to costs of care and explore the incremental effects of patient dependence measured by the Dependence Scale on costs for patients with Alzheimer's disease (AD) in Spain. The Co-Dependence in Alzheimer's Disease study is an 18 multicenter, cross-sectional, observational study among patients with AD according to the clinical dementia rating score and their caregivers in Spain. This study also gathered data on resource utilization for medical care, social care, caregiver productivity losses, and informal caregiver time reported in the Resource Utilization in Dementia Lite instrument and a complementary questionnaire. The data of 343 patients and their caregivers were collected through the completion of a clinical report form during one visit/assessment at an outpatient center or hospital, where all instruments were administered. The data collected (in addition to clinical measures) also included sociodemographic data concerning the patients and their caregivers. Cost analysis was based on resource use for medical care, social care, caregiver productivity losses, and informal caregiver time reported in the Resource Utilization in Dementia Lite instrument and a complementary questionnaire. Resource unit costs were applied to value direct medical-, social-, and indirect-care costs. A replacement cost method was used to value informal care. Patient dependence on others was measured using the Dependence Scale, and the Cumulative Index Rating Scale was administered to the patient to assess multi-morbidity. Multivariate regression analysis was used to model the effects of dependence and other sociodemographic and clinical variables on cost of care. The mean (standard deviation) costs per patient over 6 months for direct medical-, social-, indirect-, and informal-care costs were estimated at €1,028.10 (€1,655.00), €843.80 (€2,684.80), €464.20 (€1,639.00), and €33,232.20 (

    2003-01-01

    Information systems incorporating complex network structured information spaces with a semantic underpinning - such as hypermedia networks, semantic networks, topic maps, and concept maps - are being deployed to solve some of NASA s critical information management problems. This paper describes some of the human interaction and navigation problems associated with complex semantic information spaces and describes a set of new visual interface approaches to address these problems. A key strategy is to leverage semantic knowledge represented within these information spaces to construct abstractions and views that will be meaningful to the human user. Human-computer interaction methodologies will guide the development and evaluation of these approaches, which will benefit deployed NASA systems and also apply to information systems based on the emerging Semantic Web.

    1990-01-01

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

    Patients and consumers are increasingly searching the Internet for medical and healthcare information. Using the criteria of evidence-based medicine the present study analyses the websites of Wikipedia and two major German statutory health insurances for content and presentation of patient information. 22 senior students of health sciences and education evaluated one topic each. In a first step, they identified the evidence for their specific question. Afterwards they used their results as reference for the evaluation of the three websites. Using a check list each student and a second researcher independently rated content and presentation of the information offered. All these websites failed to meet relevant criteria, and key information such as the presentation of probabilities of success on patient-relevant outcomes, probabilities of unwanted effects, and unbiased risk communication was missing. On average items related to the objectives of interventions, the natural course of disease and treatment options were only rated as "partially fulfilled". Overall, there were only minor differences between the three providers, except for items related to the specific nature of the websites such as disclosure of authorship, conflict of interest and support offers. In addition, the Wikipedia information tended to achieve lower comprehensibility. In conclusion, the quality of the healthcare information provided by Wikipedia and two major German statutory health insurances is comparable. They do not meet important criteria of evidence-based patient and consumer information though.

     In the collaboration between community pharmacies and hospitals or clinics, the use of electronic medicine notebook may allow information sharing, including among out-of-network hospitals, clinics, and community pharmacies. For risk minimization, mobile or smart phones, which patients always carry with them, should be used as a tool allowing drug information to be accessed at any time. An advantage of the electronic conversion of patient drug information is that it allows patients not only to obtain round-the-clock information on drugs, etc. that they are receiving but also to check patient-oriented information selected and made easier to understand by pharmacists. In the collaboration between community pharmacies and hospitals or clinics, if, for example, patient discharge summaries are conveyed to community pharmacies via electronic medicine notebook, patients will feel reassured about the medical alliance and place more trust in pharmacists overall. This can improve patient drug awareness, thus contributing effectively to risk minimization. Drug information in electronic medicine notebook with 24-h access requires not only patients but also pharmacists to be proactive in its use. In addition, a system to facilitate the proactive use of that information needs to be established. For the electronic conversion of patient drug information and the establishment of a system promoting electronic medicine notebook use, the current status and issues need to be thoroughly examined from the viewpoint of risk communication.

  17. Putting the Focus Back on the Patient: How Privacy Concerns Affect Personal Health Information Sharing Intentions.

    2017-09-13

    Health care providers are driven by greater participation and systemic cost savings irrespective of benefits to individual patients derived from sharing Personal Health Information (PHI). Protecting PHI is a critical issue in the sharing of health care information systems; yet, there is very little literature examining the topic of sharing PHI electronically. A good overview of the regulatory, privacy, and societal barriers to sharing PHI can be found in the 2009 Health Information Technology for Economic and Clinical Health Act. This study investigated the factors that influence individuals' intentions to share their PHI electronically with health care providers, creating an understanding of how we can represent a patient's interests more accurately in sharing settings, instead of treating patients like predetermined subjects. Unlike privacy concern and trust, patient activation is a stable trait that is not subject to change in the short term and, thus, is a useful factor in predicting sharing behavior. We apply the extended privacy model in the health information sharing context and adapt this model to include patient activation and issue involvement to predict individuals' intentions. This was a survey-based study with 1600+ participants using the Health Information National Trends Survey (HINTS) data to validate a model through various statistical techniques. The research method included an assessment of both the measurement and structural models with post hoc analysis. We find that privacy concern has the most influence on individuals' intentions to share. Patient activation, issue involvement, and patient-physician relationship are significant predictors of sharing intention. We contribute to theory by introducing patient activation and issue involvement as proxies for personal interest factors in the health care context. Overall, this study found that although patients are open to sharing their PHI, they still have concerns over the privacy of their PHI

    2018-03-01

    Full Text Available Multi-Unmanned Aerial Vehicle (UAV Doppler-based target tracking has not been widely investigated, specifically when using modern nonlinear information filters. A high-degree Gauss–Hermite information filter, as well as a seventh-degree cubature information filter (CIF, is developed to improve the fifth-degree and third-degree CIFs proposed in the most recent related literature. These algorithms are applied to maneuvering target tracking based on Radar Doppler range/range rate signals. To achieve this purpose, different measurement models such as range-only, range rate, and bearing-only tracking are used in the simulations. In this paper, the mobile sensor target tracking problem is addressed and solved by a higher-degree class of quadrature information filters (HQIFs. A centralized fusion architecture based on distributed information filtering is proposed, and yielded excellent results. Three high dynamic UAVs are simulated with synchronized Doppler measurement broadcasted in parallel channels to the control center for global information fusion. Interesting results are obtained, with the superiority of certain classes of higher-degree quadrature information filters.

    2007-05-01

    This study was designed to ascertain the quality of patient information available on the World Wide Web on the topic of knee arthroscopy. For the purpose of quality analysis, we used a pool of 232 search results obtained from 7 different search engines. We used a modified assessment questionnaire to assess the quality of these Web sites. This questionnaire was developed based on similar studies evaluating Web site quality and includes items on illustrations, accessibility, availability, accountability, and content of the Web site. We also compared results obtained with different search engines and tried to establish the best possible search strategy to attain the most relevant, authentic, and adequate information with minimum time consumption. For this purpose, we first compared 100 search results from the single most commonly used search engine (AltaVista) with the pooled sample containing 20 search results from each of the 7 different search engines. The search engines used were metasearch (Copernic and Mamma), general search (Google, AltaVista, and Yahoo), and health topic-related search engines (MedHunt and Healthfinder). The phrase "knee arthroscopy" was used as the search terminology. Excluding the repetitions, there were 117 Web sites available for quality analysis. These sites were analyzed for accessibility, relevance, authenticity, adequacy, and accountability by use of a specially designed questionnaire. Our analysis showed that most of the sites providing patient information on knee arthroscopy contained outdated information, were inadequate, and were not accountable. Only 16 sites were found to be providing reasonably good patient information and hence can be recommended to patients. Understandably, most of these sites were from nonprofit organizations and educational institutions. Furthermore, our study revealed that using multiple search engines increases patients' chances of obtaining more relevant information rather than using a single search

    We developed a patient based educational video to address the information needs of women considering sacral nerve stimulation for overactive bladder. Five semistructured focus groups were used to identify patient knowledge gaps, information needs, patient acceptable terminology and video content preferences for a patient based sacral nerve stimulation educational video. Each session was transcribed, independently coded by 2 coders and examined using an iterative method. A 16-minute educational video was created to address previously identified knowledge gaps and information needs using patient footage, 3-dimensional animation and peer reviewed literature. We developed a questionnaire to evaluate participant sacral nerve stimulation knowledge and therapy attitudes. We then performed a randomized trial to assess the effect of the educational video vs the manufacturer video on patient knowledge and attitudes using our questionnaire. We identified 10 patient important domains, including 1) anatomy, 2) expectations, 3) sacral nerve stimulation device efficacy, 4) surgical procedure, 5) surgical/device complications, 6) post-procedure recovery, 7) sacral nerve stimulation side effects, 8) postoperative restrictions, 9) device maintenance and 10) general sacral nerve stimulation information. A total of 40 women with overactive bladder were randomized to watch the educational (20) or manufacturer (20) video. Knowledge scores improved in each group but the educational video group had a greater score improvement (76.6 vs 24.2 points, p <0.0001). Women who watched the educational video reported more favorable attitudes and expectations about sacral nerve stimulation therapy. Women with overactive bladder considering sacral nerve stimulation therapy have specific information needs. The video that we developed to address these needs was associated with improved short-term patient knowledge. Copyright © 2013 American Urological Association Education and Research, Inc

    2014-01-01

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

    Little is known about the information sources of Chinese patients with cancer and their family caregivers, yet this knowledge is critical for providing patient-centred care. To assess and compare the information sources used by Chinese patients with cancer and their family caregivers. The validated Health Information Wants Questionnaire (HIWQ) was translated and administered in March 2014. The oncology department of a general hospital in south-west China. A convenience sample of 198 individuals, including 79 patients with cancer (mean age=55.24, SD=13.80) and 119 family caregivers (mean age=46.83, SD=14.61). Ratings on the HIWQ items assessing information sources for different types of information. The interaction between information source and group was significant (F 3,576 =6.32, Pinformation than patients from the Internet. Caregivers and patients did not differ in the amount of information they obtained from doctors/nurses, interpersonal contacts or mass media. The interaction between information type and information source was significant (F 18,3456 =6.38, Pinformation of all types from doctors/nurses than from the other three sources and obtained more information from interpersonal contacts than from mass media or the Internet. The information sources of Chinese patients with cancer and their family caregivers were similar, with an important difference that caregivers obtained more online information than patients. These findings have important implications for patient care and education in China where the family typically plays a major role in the care and decision making. © 2016 The Authors.

    2017-05-01

    The Human-Assisted Machine Information Exploitation (HAMIE) investigation utilizes large-scale online data collection for developing models of information-based problem solving (IBPS) behavior in a simulated time-critical operational environment. These types of environments are characteristic of intelligence workflow processes conducted during human-geo-political unrest situations when the ability to make the best decision at the right time ensures strategic overmatch. The project takes a systems approach to Human Information Interaction (HII) by harnessing the expertise of crowds to model the interaction of the information consumer and the information required to solve a problem at different levels of system restrictiveness and decisional guidance. The design variables derived from Decision Support Systems (DSS) research represent the experimental conditions in this online single-player against-the-clock game where the player, acting in the role of an intelligence analyst, is tasked with a Commander's Critical Information Requirement (CCIR) in an information overload scenario. The player performs a sequence of three information processing tasks (annotation, relation identification, and link diagram formation) with the assistance of `HAMIE the robot' who offers varying levels of information understanding dependent on question complexity. We provide preliminary results from a pilot study conducted with Amazon Mechanical Turk (AMT) participants on the Volunteer Science scientific research platform.

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

    2011-04-01

    We set forth an information-theoretical measure to quantify neurotransmission reliability while taking into full account the metrical properties of the spike train space. This parametric information analysis relies on similarity measures induced by the metrical relations between neural responses as spikes flow in. Thus, in order to assess the entropy, the conditional entropy, and the overall information transfer, this method does not require any a priori decoding algorithm to partition the space into equivalence classes. It therefore allows the optimal parameters of a class of distances to be determined with respect to information transmission. To validate the proposed information-theoretical approach, we study precise temporal decoding of human somatosensory signals recorded using microneurography experiments. For this analysis, we employ a similarity measure based on the Victor-Purpura spike train metrics. We show that with appropriate parameters of this distance, the relative spike times of the mechanoreceptors' responses convey enough information to perform optimal discrimination--defined as maximum metrical information and zero conditional entropy--of 81 distinct stimuli within 40 ms of the first afferent spike. The proposed information-theoretical measure proves to be a suitable generalization of Shannon mutual information in order to consider the metrics of temporal codes explicitly. It allows neurotransmission reliability to be assessed in the presence of large spike train spaces (e.g., neural population codes) with high temporal precision.

    Information sharing between providers is critical for care coordination, especially in health systems such as the United States Department of Veterans Affairs (VA), where many patients also receive care from other health care organizations. Patients can facilitate this sharing by using the Blue Button, an online tool that promotes patients' ability to view, print, and download their health records. The aim of this study was to characterize (1) patients' use of Blue Button, an online information-sharing tool in VA's patient portal, My HealtheVet, (2) information-sharing practices between VA and non-VA providers, and (3) how providers and patients use a printed Blue Button report during a clinical visit. Semistructured qualitative interviews were conducted with 34 VA patients, 10 VA providers, and 9 non-VA providers. Interviews focused on patients' use of Blue Button, information-sharing practices between VA and non-VA providers, and how patients and providers use a printed Blue Button report during a clinical visit. Qualitative themes were identified through iterative rounds of coding starting with an a priori schema based on technology adoption theory. Information sharing between VA and non-VA providers relied primarily on the patient. Patients most commonly used Blue Button to access and share VA laboratory results. Providers recognized the need for improved information sharing, valued the Blue Button printout, and expressed interest in a way to share information electronically across settings. Consumer-oriented technologies such as Blue Button can facilitate patients sharing health information with providers in other health care systems; however, more education is needed to inform patients of this use to facilitate care coordination. Additional research is needed to explore how personal health record documents, such as Blue Button reports, can be easily shared and incorporated into the clinical workflow of providers.

    1999-01-01

    The parametric grid capability of the Knowledge Base (KBase) provides an efficient robust way to store and access interpolatable information that is needed to monitor the Comprehensive Nuclear Test Ban Treaty. To meet both the accuracy and performance requirements of operational monitoring systems, we use an approach which combines the error estimation of kriging with the speed and robustness of Natural Neighbor Interpolation. The method involves three basic steps: data preparation, data storage, and data access. In past presentations we have discussed in detail the first step. In this paper we focus on the latter two, describing in detail the type of information which must be stored and the interface used to retrieve parametric grid data from the Knowledge Base. Once data have been properly prepared, the information (tessellation and associated value surfaces) needed to support the interface functionality, can be entered into the KBase. The primary types of parametric grid data that must be stored include (1) generic header information; (2) base model, station, and phase names and associated ID's used to construct surface identifiers; (3) surface accounting information; (4) tessellation accounting information; (5) mesh data for each tessellation; (6) correction data defined for each surface at each node of the surfaces owning tessellation (7) mesh refinement calculation set-up and flag information; and (8) kriging calculation set-up and flag information. The eight data components not only represent the results of the data preparation process but also include all required input information for several population tools that would enable the complete regeneration of the data results if that should be necessary

    2013-09-01

    Data entry forms are employed in all types of enterprises to collect hundreds of customer's information on daily basis. The information is filled manually by the customers. Hence, it is laborious and time consuming to use human operator to transfer these customers information into computers manually. Additionally, it is expensive and human errors might cause serious flaws. The automatic interpretation of scanned forms has facilitated many real applications from speed and accuracy point of view such as keywords spotting, sorting of postal addresses, script matching and writer identification. This research deals with different strategies to extract customer's information from these scanned forms, interpretation and classification. Accordingly, extracted information is segmented into characters for their classification and finally stored in the forms of records in databases for their further processing. This paper presents a detailed discussion of these semantic based analysis strategies for forms processing. Finally, new directions are also recommended for future research.

    Saggion, Horacio; Funk, Adam; Maynard, Diana; Bontcheva, Kalina

    Business Intelligence (BI) requires the acquisition and aggregation of key pieces of knowledge from multiple sources in order to provide valuable information to customers or feed statistical BI models and tools. The massive amount of information available to business analysts makes information extraction and other natural language processing tools key enablers for the acquisition and use of that semantic information. We describe the application of ontology-based extraction and merging in the context of a practical e-business application for the EU MUSING Project where the goal is to gather international company intelligence and country/region information. The results of our experiments so far are very promising and we are now in the process of building a complete end-to-end solution.

    Cardiac patients have been shown to have inaccurate understanding of their cardiovascular risk. The purpose of the study was to investigate whether a guideline-based risk assessment and management intervention could facilitate understanding of cadiovascular risk and appropriate illness perceptions in cardiac patients. Randomized trial. A total of 106 patients with MI or unstable angina were randomized to receive standard care with or without a 30-min nurse-led computerized Predict CVD-Diabetes (where CVD is cardiovascular disease) session. Patients' risk perceptions (using categorical and numerical measures), and perceptions of their heart condition were assessed at admission, discharge, and 3 months. The intervention group rated the risk information as more easily understood than the control group. At discharge, they had increased perceptions of personal control, higher perceptions that a low-fat diet and regular exercise could help their condition, and believed their current illness would be shorter compared to the control group. At 3 months, no group differences were significant. The intervention had no effect on risk perceptions, which were high in both groups. Patients' perceptions of 'high' risk corresponded to numerical estimates of over 50%, which differs from clinical guidelines (over 20%). A computerized cardiovascular risk assessment and management session can help acute coronary syndrome patients understand CVD risk information and improve perceptions of control in the short term, but not change risk perceptions. In-hospital risk factor assessment and management information may help patients understand the importance of key lifestyle changes. WHAT IS ALREADY KNOWN ON THIS SUBJECT?: • Many members of the public, as well as patients with diagnosed coronary heart disease (CHD), have poor understanding of their cardiovascular disease risk. • Giving risk information can improve accuracy of risk perceptions, and may increase intentions to start preventive

    WHAT IS KNOWN ON THE SUBJECT?: Informal caregivers of psychiatric patients are vulnerable to many disturbances associated with the stress related to their activity. Caregivers who show a coping style focused on problem-solving report less psychological distress, and this approach positively influences the recovery process of the psychiatric patient. There are some questionnaires to measure coping styles in caregivers of psychiatric patients, but most of them do not have the minimum psychometric properties that a scale must fulfil. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: The authors present an adapted and validated scale for measuring both active and passive coping strategies used by informal caregivers to face daily stressful situations with psychiatric patients. The study is an example of how scales can be adapted to small samples (n strategies to support the family caregiver, as well as for measuring the results of interventions. The scale could also be used to identify how coping styles of informal caregivers are related to recovery process of psychiatric patients. Background The recovery process of a psychiatric patient is related to his primary informal caregiver's style of coping with stress. There is insufficient literature on validations of instruments that measure coping styles in this population. Objective To adapt and validate a scale to measure coping strategies in primary informal caregivers. Method The adapted scale was based on the Extreme Coping Scale of López-Vázquez and Marván. Items from that scale were adapted for application to informal caregivers. The scale was administered to 122 primary informal caregivers of patients from two psychiatric institutions in Mexico. Psychometric analyses were performed to determine the scale's properties. Results The scale was composed of 20 items (six less than in the original scale) and two factors: (i) active coping (Cronbach's alpha = .837) and (ii) passive coping (Cronbach's alpha = .718

    To synthesize findings from previous studies assessing information needs of primary care patients on the Internet and other information sources in a primary care setting. A systematic review of studies was conducted with a comprehensive search in multiple databases including OVID MEDLINE, CINAHL, and Scopus. The most common information needs among patients were information about an illness or medical condition and treatment methods, while the most common information sources were the Internet and patients' physicians. Overall, patients tend to prefer the Internet for the ease of access to information, while they trust their physicians more for their clinical expertise and experience. Barriers to information access via the Internet include the following: socio-demographic variables such as age, ethnicity, income, education, and occupation; information search skills; and reliability of health information. Further research is warranted to assess how to create accurate and reliable health information sources for both Internet and non-Internet users. © The Author(s) 2015.

    Little is known about how patient groups provide information for patients. We invited 838 patient groups from Europe and North America to participate in an online survey. The survey covered: (i) availability, accessibility and quality of information provided; (ii) methods by which patient groups communicate; (iii) ways in which patient groups acquire information and confirm its veracity/accuracy; (iv) how people access information online. European patient groups were significantly less effective in providing medical-related information than their North American counterparts in: clinical trials, potential causes of cancer, medical research, diagnosis/screening, symptoms, treatments (all p information. Similar patterns emerged for non-medical information with nutrition (information. The main barriers in accessing online information which showed differences between European and North American patients were: perceived lack of need, mainly due to faith in their doctors (p = 0.0001); limited access to the internet (p = 0.0005), limited computer skills (p = 0.02); and lower income (p = 0.027). These results emphasise the more mature nature of cancer patient engagement/information provision in North America, providing valuable insights and guidance to inform development of more robust and effective cancer patient information communication platforms in Europe.

    To determine whether health information technology (IT) systems are associated with better patient safety in acute care settings. In a cross-sectional retrospective study, data on hospital patient safety performance for October 2008 to June 2010 were combined with 2007 information technology systems data. The sample included 3002 US non-federal acute care hospitals. Electronic health record (EHR) system was coded as a composite dichotomous variable based on the presence of 10 major clinical and administrative applications that (if in use) could potentially meet stage 1 "meaningful use" objectives. The surgical IT system was measured as a dichotomous variable if a hospital used at least 1 of the perioperative, preoperative, or postoperative information systems. Hospital patient safety performance was measured by risk-standardized estimated rates per 1000 admissions. Statistical analyses were conducted using an estimated dependent variable methodology with gamma-log link-based weighted generalized linear models, adjusting for hospital characteristics, historical composite process quality, and propensity for EHR adoption. We found that the use of surgical IT systems was associated with 7% to 26% lower rates for 7 of 8 patient safety indicators (incidence rate ratio [IRR] range from 0.74 to 0.93; all P values hospitals. However, the cross-sectional design limits our ability to make causal conclusions.

    2016-05-01

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

    1999-09-01

    The benefits of early detection of prostate cancer are uncertain, and the American College of Physicians and the American Academy of Family Physicians recommend individual decision making in prostate cancer screening. This study reports the knowledge of male primary care patients about prostate cancer and prostate-specific antigen (PSA) testing and examines how that knowledge is related to PSA testing, preferences for testing in the future, and desire for involvement in physician-patient decision making. The sample included 160 men aged 45 to 70 years with no history of prostate cancer who presented for care at a university-based family medicine clinic. Before scheduled office visits, patients completed a questionnaire developed for this study that included a 10-question measure of prostate cancer knowledge, the Deber-Kraestchmer Problem-Solving Decision-Making Scale, sociodemographic indicators, and questions on PSA testing. In general, patients who were college graduates were more knowledgeable about prostate cancer and early detection than those with a high school education or less. Aside from college graduates, most patients could not identify the principle advantages and disadvantages of PSA testing. Patients indicating previous or future plans for PSA testing demonstrated greater knowledge than other patients. Desire for involvement in decision making varied by patient education but was not related to past PSA testing. Patients lack knowledge about prostate cancer and early detection. This knowledge deficit may impede the early detection of prostate cancer and is a barrier to making an informed decision about undergoing PSA testing.

    Background Patient information leaflets (PILs) are widely utilised within publically funded sexual health clinics to deliver sexual health-related information (SHRI); however, their continued value to clients in the era of social media is unclear. This study aimed to evaluate clients' opinions on three newly developed PILs and examine client views on other forms of SHRI delivery. An anonymous self-administered questionnaire was completed by clients attending the Western Sydney Sexual Health Centre (WSSHC) in 2012. High-risk population (HRP) vs non-high-risk population (non-HRP) views on PILs vs alternative methods of SHRI delivery were analysed by using Mann-Whitney U, Wilcoxon, McNemar and χ(2) tests. Over half (210/315; (67%)) of the consecutive clients from a culturally diverse population completed the survey. Sex workers (SW) and young people (YP) were significantly likely to have a high school education than non-HRP (Pmobile phone applications (Pbusiness cards (P<0.001). There was no significant difference in opinion between HRP and non-HRP. This study provides evidence for the ongoing use of PILs to deliver SHRI to clinic attendees, in conjunction with other forms of SHRI delivery such as websites and SHIL. Novel methods may require additional consumer engagement and a greater understanding of specific population's needs.

  16. An Improved Information Hiding Method Based on Sparse Representation

    2015-01-01

    Full Text Available A novel biometric authentication information hiding method based on the sparse representation is proposed for enhancing the security of biometric information transmitted in the network. In order to make good use of abundant information of the cover image, the sparse representation method is adopted to exploit the correlation between the cover and biometric images. Thus, the biometric image is divided into two parts. The first part is the reconstructed image, and the other part is the residual image. The biometric authentication image cannot be restored by any one part. The residual image and sparse representation coefficients are embedded into the cover image. Then, for the sake of causing much less attention of attackers, the visual attention mechanism is employed to select embedding location and embedding sequence of secret information. Finally, the reversible watermarking algorithm based on histogram is utilized for embedding the secret information. For verifying the validity of the algorithm, the PolyU multispectral palmprint and the CASIA iris databases are used as biometric information. The experimental results show that the proposed method exhibits good security, invisibility, and high capacity.

    This work consists of the research and unification of the guidelines transmitted to the patients and their relatives in the radioiodine therapy procedures. The goal is to provide greater understanding of the use of nuclear radiation and better understanding of treatment, to help patients better adapt to therapy, to demystify misconceptions about radiation use, and to improve care for their protection and for people close to them. Based on written and verbal information, collected in the scientific literature and in loco, accompanying the routine of the therapeutic rooms of Nuclear Medicine Services (NMS) in Rio de Janeiro, the set of actions that define scenarios experienced by radioiodine therapy patients and their helpers is being generated. Based on this information, a virtual environment is being developed in the Virtual Reality Laboratory of the Institute of Nuclear Engineering (IEN/CNEN-RJ), Brazil, a virtual environment that will allow the visualization of the procedures and instructions passed to the patients by the NMS teams. With this virtual environment, the patient will be able to immersive visualize and experience the different phases of the treatment increasing the chances of efficiency of their participation in the process.

  2. Information-based models for finance and insurance

    Science.gov (United States)

    Hoyle, Edward

    2010-10-01

    In financial markets, the information that traders have about an asset is reflected in its price. The arrival of new information then leads to price changes. The `information-based framework' of Brody, Hughston and Macrina (BHM) isolates the emergence of information, and examines its role as a driver of price dynamics. This approach has led to the development of new models that capture a broad range of price behaviour. This thesis extends the work of BHM by introducing a wider class of processes for the generation of the market filtration. In the BHM framework, each asset is associated with a collection of random cash flows. The asset price is the sum of the discounted expectations of the cash flows. Expectations are taken with respect (i) an appropriate measure, and (ii) the filtration generated by a set of so-called information processes that carry noisy or imperfect market information about the cash flows. To model the flow of information, we introduce a class of processes termed Lévy random bridges (LRBs), generalising the Brownian and gamma information processes of BHM. Conditioned on its terminal value, an LRB is identical in law to a Lévy bridge. We consider in detail the case where the asset generates a single cash flow X_T at a fixed date T. The flow of information about X_T is modelled by an LRB with random terminal value X_T. An explicit expression for the price process is found by working out the discounted conditional expectation of X_T with respect to the natural filtration of the LRB. New models are constructed using information processes related to the Poisson process, the Cauchy process, the stable-1/2 subordinator, the variance-gamma process, and the normal inverse-Gaussian process. These are applied to the valuation of credit-risky bonds, vanilla and exotic options, and non-life insurance liabilities.

    The Extensible Markup Language (XML) is increasingly being used for biomedical data exchange. The parallel growth in the use of ontologies in biomedicine presents opportunities for combining the two technologies to leverage the semantic reasoning services provided by ontology-based tools. There are currently no standardized approaches for taking XML-encoded biomedical information models and representing and reasoning with them using ontologies. To address this shortcoming, we have developed a workflow and a suite of tools for transforming XML-based information models into domain ontologies encoded using OWL. In this study, we applied semantics reasoning methods to these ontologies to automatically generate domain-level inferences. We successfully used these methods to develop semantic reasoning methods for information models in the HIV and radiological image domains.

    2013-06-01

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

  5. Managing for resilience: an information theory-based ...

    Science.gov (United States)

    Ecosystems are complex and multivariate; hence, methods to assess the dynamics of ecosystems should have the capacity to evaluate multiple indicators simultaneously. Most research on identifying leading indicators of regime shifts has focused on univariate methods and simple models which have limited utility when evaluating real ecosystems, particularly because drivers are often unknown. We discuss some common univariate and multivariate approaches for detecting critical transitions in ecosystems and demonstrate their capabilities via case studies. Synthesis and applications. We illustrate the utility of an information theory-based index for assessing ecosystem dynamics. Trends in this index also provide a sentinel of both abrupt and gradual transitions in ecosystems. In response to the need to identify leading indicators of regime shifts in ecosystems, our research compares traditional indicators and Fisher information, an information theory based method, by examining four case study systems. Results demonstrate the utility of methods and offers great promise for quantifying and managing for resilience.

    to describe the key concepts and elements used to implement a comprehensive access management system to a distributed, component-based healthcare information system. the a priori access is based on an institution-wide policy for access rights coupled to proximity process for the granting of such rights. Access rights are explicit and externalized from the information systems components. A posteriori control is based on a centralized, exhaustive journal of accesses to all components coupled to a decentralized verification process for suspicious accesses. the system has been operational for three years, initially used for the access to the computerized patient record components, and now extending to all the components of the hospital information system. The same architecture will be used for the development of the trans-institutional community health information network.

    2014-12-01

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

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

    Developed countries like USA, Canada, Japan, UK, Australia and Germany have adopted advanced traveler information technologies expeditiously in comparison to developing countries. But, unlike developed countries, developing countries face considerable financial and framework constraints. Moreover local traffic, roadway, signalization, demographic, topological and social conditions in developing countries are quite different from those in developed countries. In this paper, a comprehensive framework comprising of system architecture, development methodology and salient features of a developed Advanced Traveler Information System (ATIS) for metropolitan cities in developing countries has been discussed. Development of proposed system is based on integration of two well known information technologies viz. Geographic Information Systems (GIS) and World Wide Web (WWW). Combination of these technologies can be utilized to develop an integrated ATIS that targets different types of travelers like private vehicle owners, transit users and casual outside visitors.

    When compared to hemodialysis, peritoneal dialysis is very simple yet low cost method of renal replacement therapy. Series of studies have shown its superiority in preserving residual renal function, postponing uremic complications, maintaining the acid-base balance and achieving better post-transplant outcome in patients treated with this method. Despite obvious advantages, its role in the treatment of chronic kidney disease is still not as important as it should be. Metabolic acidosis is an inevitable complication associated with progressive loss of kidney function. Its impact on mineral and muscle metabolism, residual renal function, allograft function and anemia is very complex but can be successfully managed. The aim of our study was to evaluate the efficiency in preserving the acid-base balance in patients undergoing peritoneal dialysis at Zagreb University Hospital Center. Twenty-eight patients were enrolled in the study. The mean time spent on the treatment was 32.39 ± 43.43 months. Only lactate-buffered peritoneal dialysis fluids were used in the treatment. Acid-base balance was completely maintained in 73.07% of patients; 11.54% of patients were found in the state of mild metabolic acidosis, and the same percentage of patients were in the state of mild metabolic alkalosis. In one patient, mixed alkalosis with respiratory and metabolic component was present. The results of this study showed that acid-base balance could be maintained successfully in patients undergoing peritoneal dialysis, even only with lactate-buffered solutions included in the treatment, although they were continuously proclaimed as inferior in comparison with bicarbonate-buffered ones. In well educated and informed patients who carefully use this method, accompanied by the attentive and thorough care of their physicians, this method can provide quality continuous replacement of lost renal function as well as better quality of life.

    López, D M; Blobel, B

    2010-01-01

    Information systems integration is hard, especially when semantic and business process interoperability requirements need to be met. To succeed, a unified methodology, approaching different aspects of systems architecture such as business, information, computational, engineering and technology viewpoints, has to be considered. The paper contributes with an analysis and demonstration on how the HL7 standard set can support health information systems integration. Based on the Health Information Systems Development Framework (HIS-DF), common architectural models for HIS integration are analyzed. The framework is a standard-based, consistent, comprehensive, customizable, scalable methodology that supports the design of semantically interoperable health information systems and components. Three main architectural models for system integration are analyzed: the point to point interface, the messages server and the mediator models. Point to point interface and messages server models are completely supported by traditional HL7 version 2 and version 3 messaging. The HL7 v3 standard specification, combined with service-oriented, model-driven approaches provided by HIS-DF, makes the mediator model possible. The different integration scenarios are illustrated by describing a proof-of-concept implementation of an integrated public health surveillance system based on Enterprise Java Beans technology. Selecting the appropriate integration architecture is a fundamental issue of any software development project. HIS-DF provides a unique methodological approach guiding the development of healthcare integration projects. The mediator model - offered by the HIS-DF and supported in HL7 v3 artifacts - is the more promising one promoting the development of open, reusable, flexible, semantically interoperable, platform-independent, service-oriented and standard-based health information systems.

    Patient-reported outcome measures are helping clinicians to use evidence-based medicine in decision making. The use of computer-based questionnaires to gather such data may offer advantages over traditional paper-based methods. These advantages include consistent presentation, prompts for missed questions, reliable scoring, and simple and accurate transfer of information into databases without manual data entry. The authors enrolled 308 patients over a 16-month period from 3 orthopedic clinics: spine, upper extremity, and trauma. Patients were randomized to complete either electronic or paper validated outcome forms during their first visit, and they completed the opposite modality at their second visit, which was approximately 7 weeks later. For patients with upper-extremity injuries, the Penn Shoulder Score (PSS) was used. For patients with lower-extremity injuries, the Foot Function Index (FFI) was used. For patients with lumbar spine symptoms, the Oswestry Disability Index (ODI) was used. All patients also were asked to complete the 36-Item Short Form Health Survey (SF-36) Health Status Survey, version 1. The authors assessed patient satisfaction with each survey modality and determined potential advantages and disadvantages for each. No statistically significant differences were found between the paper and electronic versions for patient-reported outcome data. However, patients strongly preferred the electronic surveys. Additionally, the paper forms had significantly more missed questions for the FFI (P<.0001), ODI (P<.0001), and PSS (P=.008), and patents were significantly less likely to complete these forms (P<.0001). Future research should focus on limiting the burden on responders, individualizing forms and questions as much as possible, and offering alternative environments for completion (home or mobile platforms).

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

    Full Text Available Purpose: Since collecting outcome measure data from patients can be expensive, time-consuming, and subject to memory and nonresponse bias, we sought to learn whether outcomes important to patients can be obtained from data in the electronic health record (EHR or health insurance claims. Methods: We previously identified 21 outcomes rated important by patients who had advanced imaging tests for back or abdominal pain. Telephone surveys about experiencing those outcomes 1 year after their test from 321 people consenting to use of their medical record and claims data were compared with audits of the participants’ EHR progress notes over the time period between the imaging test and survey completion. We also compared survey data with algorithmically extracted data from claims files for outcomes for which data might be available from that source. Results: Of the 16 outcomes for which patients’ survey responses were considered to be the best information source, only 2 outcomes for back pain and 3 for abdominal pain had kappa scores above a very modest level of ≥ 0.2 for chart audit of EHR data and none for algorithmically obtained EHR/claims data. Of the other 5 outcomes for which claims data were considered to be the best information source, only 2 outcomes from patient surveys and 3 outcomes from chart audits had kappa scores ≥ 0.2. Conclusions: For the types of outcomes studied here, medical record or claims data do not provide an adequate source of information except for a few outcomes where patient reports may be less accurate.

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

    As health care costs alarm the nation and the debate increases about the impact of health information technologies, patients are reviewing their medical records increasingly through secure Internet portals. Important questions remain about the impact of portal use on office visits. To evaluate whether use of patient Internet portals to access records is associated with increased primary care utilization. A prospective cohort study. Primary care patients registered on patient Internet portals, within an integrated health system serving rural Pennsylvania and an academic medical center in Boston. Frequency of "clinical portal use" (days/2 mo intervals over 2 y) included secure messaging about clinical issues and viewing laboratory and radiology findings. In year 2, a subset of patients also gained access to their primary care doctor's visit notes. The main outcome was number of primary care office visits. In the first 2 months of the 2-year period, 14% of 44,951 primary care patients engaged in clinical portal use 2 or more days per month, 31% did so 1 day per month, and the remainder had no clinical portal use. Overall, adjusted for age, sex, and chronic conditions, clinical portal use was not associated with subsequent office visits. Fewer than 0.1% of patients engaged in high levels of clinical portal use (31 or more login days in 2 mo) that were associated with 1 or more additional visits in the subsequent 2 months (months 3 and 4). However, the reverse was true: office visits led to subsequent clinical portal use. Similar trends were observed among patients with or without access to visit notes. Patients turn to their portals following visits, but clinical portal use does not contribute to an increase in primary care visits.

    Full Text Available Integrated pest management (IPM involves integrating multiple pest control methods based on site information obtained through inspection, monitoring, and reports. IPM has been deployed to achieve the judicious use of pesticides and has become one of the most important methods of securing agricultural productivity. Despite the efforts made to strengthen IPM during the past decades, overuse as well as indiscriminate use of pesticides is still common. This problem is particularly serious in underserved farming communities which suffer from ineffectiveness with respect to pest management information collection and dissemination. The recent development of volunteered geographic information (VGI offers an opportunity to the general public to create and receive ubiquitous, cost-effective, and timely geospatial information. Therefore, this study proposes to enhance IPM through establishing a VGI-based IPM. As a starting point of this line of research, this study explored how such geospatial information can contribute to IPM enhancement. Based on this, a conceptual framework of VGI interaction was built to guide the establishment of VGI-based IPM. To implement VGI-based IPM, a mobile phone platform was developed. In addition, a case study was conducted in the town of Shuibian in Jiangxi province of China to demonstrate the effectiveness of the proposed approach. In the case study, by analyzing infestation incidents of an overwintering outbreak of striped rice stem borers voluntarily reported by farmers through mobile phones, spatiotemporal infestation patterns of the borers throughout the study area were revealed and disseminated to the farmers. These patterns include the dates and degree-days the pest infestations intensified, and the orientation or spatial structural variations of the clustering of the infestations. This case study showcased the unique merit of VGI in enhancing IPM, namely the acquisition of previously unrecorded spatial data in a cost

    Long queues and wait times often occur at hospitals and affect smooth delivery of health services. To improve hospital operations, prior studies have developed scheduling techniques to minimize patient wait times. However, these studies lack in demonstrating how such techniques respond to real-time information needs of hospitals and efficiently manage wait times. This article presents a multi-method study on the positive impact of providing real-time scheduling information to patients using the RFID technology. Using a simulation methodology, we present a generic scenario, which can be mapped to real-life situations, where patients can select the order of laboratory services. The study shows that information visibility offered by RFID technology results in decreased wait times and improves resource utilization. We also discuss the applicability of the results based on field interviews granted by hospital clinicians and administrators on the perceived barriers and benefits of an RFID system.

    Evidence based on average patient data, which occupies most of our present day information databases, does not fulfil the needs of individual patient-centred health care. In spite of the unprecedented expansion in medical information we still do not have the types of information required to allow us to tailor optimal care for a given individual patient. As our current information is chiefly provided in disconnected silos, we need an information system that can seamlessly integrate different types of information to meet diverse user group needs. Groups of certain individual medical learners namely patients, medical students and health professionals share the patient's need to increasingly interact with and seek knowledge and solutions offered by others (individual medical learners) who have the lived experiences that they would benefit to access and learn from. A web-based user-driven learning solution may be a stepping-stone to address the present problem of information oversupply in medicine that mostly remains underutilized, as it doesn't meet the needs of the individual patient and health professional user. The key to its success would be to relax central control and make local trust and strategic health workers feel more engaged in the project such that it is truly user-driven.

    A new information publishing system based on Internet of things is proposed, which is composed of four level hierarchical structure, including the screen identification layer, the network transport layer, the service management layer and the publishing application layer. In the architecture, the screen identification layer has realized the internet of screens in which geographically dispersed independent screens are connected to the internet by the customized set-top boxes. The service management layer uses MQTT protocol to implement a lightweight broker-based publish/subscribe messaging mechanism in constrained environments such as internet of things to solve the bandwidth bottleneck. Meanwhile the cloud-based storage technique is used to storage and manage the promptly increasing multimedia publishing information. The paper has designed and realized a prototype SzIoScreen, and give some related test results.

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

  1. Utility-based early modulation of processing distracting stimulus information.

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

    The aim of this study was to identify disease-related knowledge and information needs of patients with inflammatory bowel disease. The 313 patients (Crohn disease: n = 169, colitis: n = 144) presenting to an outpatient gastroenterology clinic of a tertiary care hospital in Seoul, Republic of Korea, were scored on their knowledge of Crohn disease and colitis and their information needs were assessed in the questionnaire. Patients with Crohn disease obtained a higher mean knowledge score than patients with colitis. The patients with Crohn disease had significantly higher scores about complications than patients with colitis. The patients with Crohn disease showed significantly higher mean scores relating to the patients' information needs than patients with colitis. The favorite topics of information needed were disease, medication, and diagnosis/operations. The patients with Crohn disease wanted more information than patients with colitis about medications used for treatment, daily life, and pregnancy. The effectiveness of the training and education given to patients can be maximized in this education system when the information about disease and medications for Crohn disease patients or information about disease and diet for colitis patients is primarily provided according to the degree of the patients' need for information.

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

    The architecture and working of a recently implemented knowledge-based geographic information system (KBGIS-2) that was designed to satisfy several general criteria for the geographic information system are described. The system has four major functions that include query-answering, learning, and editing. The main query finds constrained locations for spatial objects that are describable in a predicate-calculus based spatial objects language. The main search procedures include a family of constraint-satisfaction procedures that use a spatial object knowledge base to search efficiently for complex spatial objects in large, multilayered spatial data bases. These data bases are represented in quadtree form. The search strategy is designed to reduce the computational cost of search in the average case. The learning capabilities of the system include the addition of new locations of complex spatial objects to the knowledge base as queries are answered, and the ability to learn inductively definitions of new spatial objects from examples. The new definitions are added to the knowledge base by the system. The system is currently performing all its designated tasks successfully, although currently implemented on inadequate hardware. Future reports will detail the performance characteristics of the system, and various new extensions are planned in order to enhance the power of KBGIS-2.

    Internet has become a major tool for patients to search for health-related information and to communicate on health. We currently lack data on how patients with psychiatric disorders access and use Internet to search for information on their mental health. This study aimed to assess, in patients followed for a psychiatric disorder (schizophrenia, bipolar disorder, mood and anxiety disorder, substance-related and addictive disorders and eating disorders), prevalence of Internet access and use, and patient expectations and needs regarding the use of Internet to search for mental-health information depending on the psychiatric disorder. We conducted this cross-sectional study between May 2013 and July 2013 in 648 patients receiving psychiatric care in 8 hospitals from the Region Centre, France. We used multivariate logistic regression adjusted for age, gender, socio-educational level and professional status to compare use, expectations and needs regarding Internet-based information about the patient's psychiatric disorder (65-items self-administered questionnaires) as a function of the psychiatric disorders. We identified patients clusters with multiple correspondence analysis and ascending hierarchical classification. Although 65.6% of our population accessed Internet at home, prevalence for Internet access varied depending on the type of psychiatric disorder and was much more related to limited access to a computer and low income than to a lack of interest in the Internet. Most of the patients who used Internet were interested in having access to reliable Internet-based information on their health (76.8%), and most used Internet to search for Internet based health-information about their psychiatric disorder (58.8%). We found important differences in terms of expectations and needs depending on the patient's psychiatric disorder (e.g., higher interest in Internet-based information among patients with bipolar disorder, substance-related and addictive disorders

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

    Information broadcast (IB) is a critical process in complex network, usually accomplished by flooding mechanism. Although flooding is simple and no prior topological information is required, it consumes a lot of transmission overhead. Another extreme is the tree-based broadcast (TB), for which information is disseminated via a spanning tree. It achieves the minimal transmission overhead but the maintenance of spanning tree for every node is an obvious obstacle for implementation. Motivated by the success of scale-free network models for real-world networks, in this paper, we investigate the issues in IB by considering an alternative solution in-between these two extremes. A novel relay-based broadcast (RB) mechanism is proposed by employing a subset of nodes as relays. Information is firstly forwarded to one of these relays and then re-disseminated to others through the spanning tree whose root is the relay. This mechanism provides a trade-off solution between flooding and TB. On one hand, it saves up a lot of transmission overhead as compared to flooding; on the other hand, it costs much less resource for maintenance than TB as only a few spanning trees are needed. Based on two major criteria, namely the transmission overhead and the convergence time, the effectiveness of RB is confirmed. The impacts of relay assignment and network structures on performance are also studied in this work.

    Many space-related processes are highly complex systems subject to sudden, major transients. In any complex process control system, a critical aspect is rapid analysis of the changing process information. During a disturbance, this task can overwhelm humans as well as computers. Humans deal with this by applying heuristics in determining significant information. A simple, knowledge-based approach to prioritizing information is described. The approach models those heuristics that humans would use in similar circumstances. The approach described has received two patents and was implemented in the Alarm Filtering System (AFS) at the Idaho National Engineering Laboratory (INEL). AFS was first developed for application in a nuclear reactor control room. It has since been used in chemical processing applications, where it has had a significant impact on control room environments. The approach uses knowledge-based heuristics to analyze data from process instrumentation and respond to that data according to knowledge encapsulated in objects and rules. While AFS cannot perform the complete diagnosis and control task, it has proven to be extremely effective at filtering and prioritizing information. AFS was used for over two years as a first level of analysis for human diagnosticians. Given the approach's proven track record in a wide variety of practical applications, it should be useful in both ground- and space-based systems.

    Health services research of Latinos with limited English proficiency (LEP) have largely focused on studying disparities related to patient-provider communication. Less is known about their non-provider interactions such as those with patient registration systems and clinic front office staff; these interactions precede the encounter with providers and may shape how comfortable patients feel about their overall health services experience. This study explored Latino patients with LEP experiences with, and expectations for, interactions with patient registration systems and front office staff. We conducted 20 in-depth interviews with Latinos with LEP (≥ 18 years of age) who seek health services in the Piedmont Triad region, North Carolina. We analyzed participants' quotes and identified themes by using a constant comparison method. This research was conducted by a community-academic partnership; partners were engaged in study design, instrument development, recruitment, data analysis, and manuscript writing. Qualitative analysis allowed us to identify the following recurring themes: 1) inconsistent registration of multiple surnames may contribute to patient misidentification errors and delays in receiving health care; 2) lack of Spanish language services in front office medical settings negatively affect care coordination and satisfaction with health care; and 3) perceived discrimination generates patients' mistrust in front office staff and discomfort with services. Latino patients in North Carolina experience health services barriers unique to their LEP background. Participants identified ways in which the lack of cultural and linguistic competence of front office staff negatively affect their experiences seeking health services. Healthcare organizations need to support their staff to encourage patient-centered principles.

    The instantaneous spread of information, low costs, and broad availability of information and communication technologies (ICTs) make them an attractive platform for managing care, patient communication, and medical interventions in cancer treatment. There is little information available in Latin America about the level of usage of ICTs for and by cancer patients. Our study attempts to fill this gap. The aim of this study was to assess the level of ICT use and patterns of preferences among cancer patients. We conducted an anonymous cross-sectional survey study in 500 Ecuadorian cancer patients. This questionnaire consisted of 22 items about demographic and clinical data, together with the preferences of people who use ICTs. Chi-square, crude, and adjusted logistic regressions were performed. Of the total, 43.2% (216/500) of participants reported that they had access to the Internet, and 25.4% (127/500) reported that they neither owned a cell phone nor did they have access to the Internet. The Internet constituted the highest usage rate as a source of information about malignant diseases (74.3%, 162/218) regardless of age (PWhatsApp (66.5%, 145/218) and short message service (SMS) text messaging (61.0%, 133/218) were widely reported as interesting communication channels. Similarly, WhatsApp (72.0%, 157/218) followed by SMS (63.8%, 139/218) were reported as the preferred ICTs through which patients would like to ask physicians about diseases. Adjusted regression analysis showed that patients aged between 40 and 64 years were more likely to be interested in receiving information through SMS (odds ratio, OR 5.09, 95% CI 1.92-13.32), as well as for asking questions to physicians through this same media (OR 9.78, CI 3.45-27.67) than the oldest group. WhatsApp, SMS, and email are effective and widely used ICTs that can promote communication between cancer patients and physicians. According to age range, new ICTs such as Facebook are still emerging. Future studies should

    An information security scheme based on computational temporal ghost imaging is proposed. A sequence of independent 2D random binary patterns are used as encryption key to multiply with the 1D data stream. The cipher text is obtained by summing the weighted encryption key. The decryption process can be realized by correlation measurement between the encrypted information and the encryption key. Due to the instinct high-level randomness of the key, the security of this method is greatly guaranteed. The feasibility of this method and robustness against both occlusion and additional noise attacks are discussed with simulation, respectively.

  15. Neighborhood Hypergraph Based Classification Algorithm for Incomplete Information System

    2015-01-01

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

    This study presents a model of psychic change in personality disorders focusing on three dimensions: felt safety, mentalization and self-object relations. Based upon this model a hospitalization-based therapy program was created. Four scales to measure these three dimensions on the Object Relation Interview are discussed: the Felt Safety Scale, the Reflective Functioning Scale and the Bion Grid Scale and the Differentiation-Relatedness Scale. A naturalistic symptom outcome study of the program showed a large effect on both symptoms and personality functioning. Furthermore, trajectory based on pre-treatment patient characteristics (i.e., anaclitic versus introjective personality styles). Importantly, we also found a relation between symptomatic and personality change and change in felt safety and object relations. At 5-year follow-up, patients showed sustained improvement in symptomatic distress and further improvement in terms of personality and interpersonal functioning.

  17. Patient-Focused Benefit-Risk Analysis to Inform Regulatory Decisions: The European Union Perspective.

    Science.gov (United States)

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

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

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

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

    Science.gov (United States)

    Arvonio, Maria Marra

    2014-01-01

    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.

    2007-01-01

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

    The Human Acts Simulation Program (HASP) started as a ten year program of Computing and Information Systems Center (CISC) at Japan Atomic Energy Research Institute (JAERI) in 1987. A mechanical design study of biped locomotion robots for patrol and inspection in nuclear facilities is being performed as an item of the research scope. One of the goals of our research is to design a biped locomotion robot for practical use in nuclear facilities. So far, we have been studying for several dynamic walking patterns. In conventional control methods for biped locomotion robots, the program control is used based on preset walking patterns, so it dose not have the robustness such as a dynamic change of walking pattern. Therefore, a real-time control method based on dynamic information of the robot states is necessary for the high performance of walking. In this study a new control method based on Zero Moment Point (ZMP) information is proposed as one of real-time control methods. The proposed method is discussed and validated based on the numerical simulation. (author).

    Introducing workflow management technology in healthcare seems to be prospective in dealing with the problem that the current healthcare Information Systems cannot provide sufficient support for the process management, although several challenges still exist. The purpose of this paper is to study the method of developing workflow-based information system in radiology department as a use case. First, a workflow model of typical radiology process was established. Second, based on the model, the system could be designed and implemented as a group of loosely coupled components. Each component corresponded to one task in the process and could be assembled by the workflow management system. The legacy systems could be taken as special components, which also corresponded to the tasks and were integrated through transferring non-work- flow-aware interfaces to the standard ones. Finally, a workflow dashboard was designed and implemented to provide an integral view of radiology processes. The workflow-based Radiology Information System was deployed in the radiology department of Zhejiang Chinese Medicine Hospital in China. The results showed that it could be adjusted flexibly in response to the needs of changing process, and enhance the process management in the department. It can also provide a more workflow-aware integration method, comparing with other methods such as IHE-based ones. The workflow-based approach is a new method of developing radiology information system with more flexibility, more functionalities of process management and more workflow-aware integration. The work of this paper is an initial endeavor for introducing workflow management technology in healthcare. (orig.)

    The aim of this study was to evaluate the quality and value of web-based information on advance directives. Internet-based information on advance directives was selected because, if it is inaccurate or difficult to understand, patients risk making decisions about their care that may not be followed in practice. Two validated health information evaluation tools, the Suitability Assessment of Materials and DISCERN, and a focus group were used to assess credibility, user orientation and effectiveness. Only one of the 34 internet-based information items on advance directives reviewed fulfilled the study criteria and 30% of the sites were classed as unreadable. In terms of learning and informing, 79% of the sites were considered unsuitable. Using health literacy tools to evaluate internet-based health information highlights that often it is not at a functional literacy level and neither informs nor empowers users to make independent and valid healthcare decisions. ©2017 RCN Publishing Company Ltd.

    Information systems with clinical decision support (CDS) offer great potential to assist the co-ordination of patients with chronic diseases and to improve patient care. Despite this, few have entered routine clinical use. Tuberculosis (TB) is an infection of public health importance. It has complex interactions with many comorbid conditions, requires close supervised care and prolonged treatment for effective cure. These features make it suitable for use with an information management system with CDS features. In close consultation with key stakeholders, a clinical application was developed for the management of TB patients in Victoria. A formal usability assessment using semi-structured case-scenario based exercises was performed. Subjects were 12 individuals closely involved in the care of TB patients, including Infectious Diseases and Respiratory Physicians, and Public Health Nurses. Two researchers conducted the sessions, independently analysed responses and discrepancies compared to the voice record for validity. Despite varied computer experience, responses were positive regarding user interface and content. Data location was not always intuitive, however this improved with familiarity of the program. Decision support was considered valuable, with useful suggestions for expansion of these features. Automated reporting for correspondence and notification to the Health Department were felt worth the initial investment in data entry. An important workflow-based issue regarding dismissal of alerts and several errors were detected. Usability assessment validated many design elements of the system, provided a unique insight into workflow issues faced by users and hopefully will impact on its ultimate clinical utility.

    2009-01-01

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

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

    2017-12-01

    Recent research findings on modeling actual evapotranspiration (ET) using remote sensing data and methods have proven the ability of these methods to address wide range of hydrological and water resources issues including river basin water balance for improved water resources management, drought monitoring, drought impact and socioeconomic responses, agricultural water management, optimization of land-use for water conservations, water allocation agreement among others. However, there is still a critical need to identify appropriate type of ET information that can address each of these issues. The current trend of increasing demand for water due to population growth coupled with variable and limited water supply due to drought especially in arid and semiarid regions with limited water supply have highlighted the need for such information. To properly address these issues different spatial and temporal resolutions of ET information will need to be used. For example, agricultural water management applications require ET information at field (30-m) and daily time scales while for river basin hydrologic analysis relatively coarser spatial and temporal scales can be adequate for such regional applications. The objective of this analysis is to evaluate the potential of using an integrated ET information that can be used to address some of these issues collectively. This analysis will highlight efforts to address some of the issues that are applicable to New Mexico including assessment of statewide water budget as well as drought impact and socioeconomic responses which all require ET information but at different spatial and temporal scales. This analysis will provide an evaluation of four remote sensing based ET models including ALEXI, DisALEXI, SSEBop, and SEBAL3.0. The models will be compared with ground-based observations from eddy covariance towers and water balance calculations. Remote sensing data from Landsat, MODIS, and VIIRS sensors will be used to provide ET

    An intelligent information technology based system could have a positive impact on the life-style of patients suffering from chronic diseases by providing useful health recommendations. In this paper, we have proposed a hybrid model that provides disease prediction and medical recommendations to cardiac patients. The first part aims at implementing a prediction model, that can identify the disease of a patient and classify it into one of the four output classes i.e., non-cardiac chest pain, silent ischemia, angina, and myocardial infarction. Following the disease prediction, the second part of the model provides general medical recommendations to patients. The recommendations are generated by assessing the severity of clinical features of patients, estimating the risk associated with clinical features and disease, and calculating the probability of occurrence of disease. The purpose of this model is to build an intelligent and adaptive recommender system for heart disease patients. The experiments for the proposed recommender system are conducted on a clinical data set collected and labelled in consultation with medical experts from a known hospital. The performance of the proposed prediction model is evaluated using accuracy and kappa statistics as evaluation measures. The medical recommendations are generated based on information collected from a knowledge base created with the help of physicians. The results of the recommendation model are evaluated using confusion matrix and gives an accuracy of 97.8%. The proposed system exhibits good prediction and recommendation accuracies and promises to be a useful contribution in the field of e-health and medical informatics. Copyright © 2017 Elsevier B.V.

    Rumor spreading can have a significant impact on people's lives, distorting scientific facts and influencing political opinions. With technologies that have democratized the production and reproduction of information, the rate at which misinformation can spread has increased significantly, leading many to describe contemporary times as a 'post-truth era'. Research into rumor spreading has primarily been based on either model of social and biological contagion, or upon models of opinion dynamics. Here we present a comprehensive model that is based on information entropy, which allows for the incorporation of considerations like the role of memory, conformity effects, differences in the subjective propensity to produce distortions, and variations in the degree of trust that people place in each other. Variations in the degree of trust are controlled by a confidence factor β, while the propensity to produce distortions is controlled by a conservation factor K. Simulations were performed using a Barabási-Albert (BA) scale-free network seeded with a single piece of information. The influence of β and K upon the temporal evolution of the system was subsequently analyzed regarding average information entropy, opinion fragmentation, and the range of rumor spread. These results can aid in decision-making to limit the spread of rumors.

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

    2012-12-01

    The aims of this study were to describe the profile of urological cancer patients who look for health information on the Internet and to analyse the factors related to use of the Internet as a source of health information. A cross-sectional descriptive study using individual, semi-structured, questionnaire-based interviews was carried out in oncology clinics in a hospital in Granada (Spain) in a sample group of 169 patients with prostate, bladder and kidney cancer. The dependent variable was use of the Internet as a source of health information. The independent variables were sociodemographic variables, health status, relationship with healthcare services, patient's role in decision-making process, satisfaction with healthcare, Internet use, Internet skills and attitude. Data analyses include descriptive, bivariate and multivariate analyses. Of the patients in the sample group, 72.2 % had prostate cancer, 19.4 % had bladder cancer and 8.3 % had kidney cancer. Only 11.2 % of patients in the group used the Internet as a source of health information. These patients were typically men of an average age of 62 years, who live in urban areas, who have completed secondary or university education, with a high income and who usually share the role of decision maker with their doctor. Patients who use the Internet as a source of health information usually look for support from psychological support groups, have family members who also look for information on the Internet and prefer sources of information other than those provided by the health services. The study outlines the profile of urological cancer patients who use the Internet as a source of health information. Internet use is related to a patient's attitude towards decision making, level of education and whether or not they look for information from sources other than the health system itself.

    Methods used in information filtering and recommendation often rely on quantifying the similarity between objects or users. The used similarity metrics often suffer from similarity redundancies arising from correlations between objects' attributes. Based on an unweighted undirected object-user bipartite network, we propose a Corrected Redundancy-Eliminating similarity index (CRE) which is based on a spreading process on the network. Extensive experiments on three benchmark data sets-Movilens, Netflix and Amazon-show that when used in recommendation, the CRE yields significant improvements in terms of recommendation accuracy and diversity. A detailed analysis is presented to unveil the origins of the observed differences between the CRE and mainstream similarity indices.

    Al-Jaljouli, Raja; Abawajy, Jemal

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

    2016-04-01

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

    Full Text Available Selection of an appropriate renal replacement modality is of utmost importance for patients with end stage renal disease. Previous studies showed provision of information to and free modality choice by patients to be suboptimal. Therefore, the European Kidney Patients' Federation (CEAPIR explored European patients' perceptions regarding information, education and involvement on the modality selection process.CEAPIR developed a survey, which was disseminated by the national kidney patient organisations in Europe.In total, 3867 patients from 36 countries completed the survey. Respondents were either on in-centre haemodialysis (53% or had a functioning graft (38% at the time of survey. The majority (78% evaluated the general information about kidney disease and treatment as helpful, but 39% did not recall being told about alternative treatment options than their current one. Respondents were more often satisfied with information provided on in-centre haemodialysis (90% and transplantation (87% than with information provided on peritoneal dialysis (79% or home haemodialysis (61%, and were more satisfied with information from health care professionals vs other sources such as social media. Most (75% felt they had been involved in treatment selection, 29% perceived they had no free choice. Involvement in modality selection was associated with enhanced satisfaction with treatment (OR 3.13; 95% CI 2.72-3.60. Many respondents (64% could not remember receiving education on how to manage their kidney disease in daily life. Perceptions on information seem to differ between countries.Kidney patients reported to be overall satisfied with the information they received on their disease and treatment, although information seemed mostly to have been focused on one modality. Patients involved in modality selection were more satisfied with their treatment. However, in the perception of the patients, the freedom to choose an alternative modality showed room for

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

    The information needs of cancer patients are highly variable. Literature suggests an improved ability to modulate personalised stress, increased patient involvement with decision making, greater satisfaction with treatment choices and reduced anxiety levels in cancer patients who have access to information. The aim of this project was to evaluate the effects of a mobile information application on anxiety levels of patients undergoing surgery for breast cancer. An application was developed for use with Apple iPad containing information on basic breast cancer biology, different treatments used and surgical techniques. Content and face validity studies were performed. A randomized control trial was designed, with a 1:2 allocation. Data collected include basic demographics and type of surgery. Questionnaires used included: the HADS, Mini-MAC, information technology familiarity and information satisfaction. A total of 39 women participated. 13 women had access to an iPad containing additional information and 26 women acted as controls. The mean age was 54 and technology familiarity was similar among both groups. Anxiety and depression scores at seven days were significantly lower in control patients without access to the additional information provided by the mobile application (p = 0.022 and 0.029 respectively). Anxiety and depression in breast cancer patients is both multifactorial and significant, with anxiety levels directly correlating with reduced quality of life. Intuitively, information should improve anxiety levels, however, we have demonstrated that surgical patients with less information reported significantly lower anxiety. We advise the thorough testing and auditing of information initiatives before deployment. Copyright © 2016 Elsevier Ltd. All rights reserved.

  2. Computer-based safeguards information and accounting system

    Acquiring, processing and analysing information about inventories and flow of nuclear materials are essential parts of IAEA safeguards. Safeguards information originates from several sources. The information to be provided is specified in the various safeguards agreements between the States and the IAEA, including both NPT agreements and safeguards trilateral agreements. Most of the safeguards information currently received by the IAEA is contained in accounting reports from the States party to the NPT. Within the frame of the material balance concept of NPT, three types of reports are provided to the IAEA by the States: Physical Inventory Listings (PIL); Inventory Change Reports (ICR); Material Balance Reports (MBR). In addition, facility design information is reported when NPT safeguards are applied and whenever there is a change in the facility or its operation. Based on this data, an accounting system is used to make available such information as the book inventories of nuclear material as a function of time, material balance evaluations, and analysis of shipments versus receipts of nuclear material. A second source of NPT safeguards information is the inspection activities carried out in the field as a necessary counterpart for verification of the data presented by the States in their accounting reports. The processing of inspection reports and other inspection data is carried out by the present system in a provisional manner until a new system, which is under development is available. The major effort currently is directed not to computer processing but toward developing and applying uniform inspection procedures and information requirements. A third source of NPT safeguards information is advanced notifications and notifications of transfer of source materials before the starting point of safeguards. Since, however, the States are not completely aware of the need and requirement to provide these data, this is a point to be emphasized in future workshops and

    This paper proposes an approach to facilitate the process of individualization of patients from their medical images, without compromising the inherent confidentiality of medical data. The identification of a patient from a medical image is not often the goal of security methods applied to image records. Usually, any identification data is removed from shared records, and security features are applied to determine ownership. We propose a method for embedding a QR-code containing information that can be used to individualize a patient. This is done so that the image to be shared does not differ significantly from the original image. The QR-code is distributed in the image by changing several pixels according to a threshold value based on the average value of adjacent pixels surrounding the point of interest. The results show that the code can be embedded and later fully recovered with minimal changes in the UIQI index - less than 0.1% of different.

    Despite the potential of eHealth services to revolutionize the way healthcare and prevention is provided many applications developed for patients fail to deliver their promise. Therefore, the aim of this study is to use patient journey mapping to explore post-discharge stroke patients' information needs to propose eHealth services that meet their needs throughout their care and rehabilitation processes. Three focus groups with younger ( = 65 years) stroke patients were performed. Content analysis was used to analyse the data. Stroke patients' information needs was explored using patient journey model. Four main events (discharge from hospital, discharge from rehab clinic, coming home, and clinical encounters) and two phases (at rehab clinic, at home) have been identified in patients' post-discharge journey. The main categories identified in this study indicate that patients not only need to have access to health related information about their care and rehabilitation processes but also practical guidance through healthcare and community services. Patients also have different information needs at different events and during different phases. Potential supportive eHealth services were suggested by the researchers considering different parts of the patients' journeys. Patient journey models and qualitative analysis of patients' information needs are powerful tools that can be used to improve healthcare from a patient perspective. As patients' understanding of their illness changes over time, their need of more flexible support throughout the care and rehabilitation processes increases. To design appropriate eHealth services that meet patients' information needs, it is imperative to understand the current care and rehabilitation processes and identify patients' information needs throughout their journey.

    Ubiquitous health is defined as a dynamic network of interconnected systems that offers health services independent of time and location to a data subject (DS). The network takes place in open and unsecure information space. It is created and managed by the DS who sets rules that regulate the way personal health information is collected and used. Compared to health care, it is impossible in ubiquitous health to assume the existence of a priori trust between the DS and service providers and to produce privacy using static security services. In ubiquitous health features, business goals and regulations systems followed often remain unknown. Furthermore, health care-specific regulations do not rule the ways health data is processed and shared. To be successful, ubiquitous health requires novel privacy architecture. The goal of this study was to develop a privacy management architecture that helps the DS to create and dynamically manage the network and to maintain information privacy. The architecture should enable the DS to dynamically define service and system-specific rules that regulate the way subject data is processed. The architecture should provide to the DS reliable trust information about systems and assist in the formulation of privacy policies. Furthermore, the architecture should give feedback upon how systems follow the policies of DS and offer protection against privacy and trust threats existing in ubiquitous environments. A sequential method that combines methodologies used in system theory, systems engineering, requirement analysis, and system design was used in the study. In the first phase, principles, trust and privacy models, and viewpoints were selected. Thereafter, functional requirements and services were developed on the basis of a careful analysis of existing research published in journals and conference proceedings. Based on principles, models, and requirements, architectural components and their interconnections were developed using system

    A shift from a predominantly emergency service, towards one where a wide range of conditions are managed and treated on scene presents numerous challenges for ambulance services and clinicians. The effective management of a broad range of patients and conditions in the ambulance setting will have an impact on other parts of the health service including emergency departments and primary care. A two part online survey was distributed to operational staff working for a regional UK ambulance service. Clinicians were asked to report their experiences of accessing patient information and making decisions about patient management based on four hypothetical patient scenarios. A survey of clinical staff (n = 302) revealed that (i) the vast majority experienced difficulties in accessing patients' health information, (ii) this was particularly true in the out of hours period and (iii) They felt that better access would likely lead to more appropriate selection of care pathways. Decisions regarding the most appropriate care for patients presenting to the ambulance service are best informed by access to accurate and complete health information and records. An understanding of patients' pre-existing medical conditions, recent treatments and health information is needed for the selection of the most appropriate care; this information is often difficult to obtain in the ambulance service setting.

    Srinagarind Hospital has 150-200 patients with cleft lip and palate each year. When patients are admitted to hospital for surgery patients and family feel they are in a crisis of life, they feel fear anxiety and need to know about how to take care of wound, they worry if patient will feel pain, how to feed patients and many things about patients. Information is very important for patients/family to prevent complications and help their decision process, decrease parents stress and encourage better co-operation. To develop information system for patients with cleft lip-palate undergoing operation. This is an action research divided into 3 phases. Phase 1 Situation review: in this phase we interview, nursing care observation, and review nursing documents about the information giving. Phase 2 Develop information system: focus groups, for discussion about what nurses can do to develop the system to give information to patients/parents. Phase 3 evaluation: by interviewing 61 parents using the structure questionnaire. 100 percent of patients/parents received information but some items were not received. Patients/parents satisfaction was 94.9 percent, no complications. The information system development provides optimal care for patients and family with cleft lip and palate, but needs to improve some techniques or tools to give more information and evaluate further the nursing outcome after.

    Regional networking between services that provide mental health care in Brazil's decentralized public health system is challenging, partly due to the simultaneous existence of services managed by municipal and state authorities and a lack of efficient and transparent mechanisms for continuous and updated communication between them. Since 2011, the Ribeirao Preto Medical School and the XIII Regional Health Department of the Sao Paulo state, Brazil, have been developing and implementing a web-based information system to facilitate an integrated care throughout a public regional mental health care network. After a profound on-site analysis, the structure of the network was identified and a web-based information system for psychiatric admissions and discharges was developed and implemented using a socio-technical approach. An information technology team liaised with mental health professionals, health-service managers, municipal and state health secretariats and judicial authorities. Primary care, specialized community services, general emergency and psychiatric wards services, that comprise the regional mental healthcare network, were identified and the system flow was delineated. The web-based system overcame the fragmentation of the healthcare system and addressed service specific needs, enabling: detailed patient information sharing; active coordination of the processes of psychiatric admissions and discharges; real-time monitoring; the patients' status reports; the evaluation of the performance of each service and the whole network. During a 2-year period of operation, it registered 137 services, 480 health care professionals and 4271 patients, with a mean number of 2835 accesses per month. To date the system is successfully operating and further expanding. We have successfully developed and implemented an acceptable, useful and transparent web-based information system for a regional mental healthcare service network in a medium-income country with a decentralized

    Analyzing the characteristic of multi-Agent and geographic Ontology, The concept of the Agent-based Spatial Information Semantic Grid (ASISG) is defined and the architecture of the ASISG is advanced. ASISG is composed with Multi-Agents and geographic Ontology. The Multi-Agent Systems are composed with User Agents, General Ontology Agent, Geo-Agents, Broker Agents, Resource Agents, Spatial Data Analysis Agents, Spatial Data Access Agents, Task Execution Agent and Monitor Agent. The architecture of ASISG have three layers, they are the fabric layer, the grid management layer and the application layer. The fabric layer what is composed with Data Access Agent, Resource Agent and Geo-Agent encapsulates the data of spatial information system so that exhibits a conceptual interface for the Grid management layer. The Grid management layer, which is composed with General Ontology Agent, Task Execution Agent and Monitor Agent and Data Analysis Agent, used a hybrid method to manage all resources that were registered in a General Ontology Agent that is described by a General Ontology System. The hybrid method is assembled by resource dissemination and resource discovery. The resource dissemination push resource from Local Ontology Agent to General Ontology Agent and the resource discovery pull resource from the General Ontology Agent to Local Ontology Agents. The Local Ontology Agent is derived from special domain and describes the semantic information of local GIS. The nature of the Local Ontology Agents can be filtrated to construct a virtual organization what could provides a global scheme. The virtual organization lightens the burdens of guests because they need not search information site by site manually. The application layer what is composed with User Agent, Geo-Agent and Task Execution Agent can apply a corresponding interface to a domain user. The functions that ASISG should provide are: 1) It integrates different spatial information systems on the semantic The Grid
