This study aimed to compare information provided on student counseling center websites of universities and colleges in Japan, the United States, the United Kingdom, and Taiwan. A survey was conducted on websites of 315 centers in Japan, 282 centers in the United States, 70 centers in the United Kingdom and 61 centers in Taiwan. Trends in the provision of information on websites in each country were analyzed and compared for the rate and quantity of information published. Results of multiple correspondence analyses indicated two basic dimensions of information that could effectively distinguish information provided in the four countries. These were provision of necessary information and provision of information for use of individual counseling or support of community. Finally, issues related to websites in student counseling centers of Japanese universities and colleges are discussed.

Objectives Unlike information provided for research, information disclosed to patients for treatment or procedures is largely unregulated and, as such, there is likely considerable variability in the type and amount of disclosure. This study was designed to examine the nature of information provided to parents regarding options for postoperative pain control and their understanding thereof. Methods 187 parents of children scheduled to undergo a surgical procedure requiring inpatient postoperative pain control completed questionnaires that elicited information regarding their perceptions and understanding of, and satisfaction with, information regarding postoperative pain management. Results Results showed that there was considerable variability in the content and amount of information provided to parents based on the method of postoperative pain control provided. Parents whose child received Patient Controlled Analgesia (PCA) were given significantly (P< 0.025) more information on the risks and benefits compared to those receiving Nurse Controlled or intravenous-prn (NCA or IV) analgesia. Approximately one third of parents had no understanding of the risks associated with postoperative pain management. Parents who received pain information preoperatively and who were given information regarding the risks and benefits had improved understanding compared to parents who received no or minimal information (P< 0.001). Furthermore, information that was deemed unclear or insufficient resulted in decreased parental understanding. Discussion These results demonstrate the variability in the type and amount of information provided to parents regarding their child’s postoperative pain control and reinforce the importance of clear and full disclosure of pain information, particularly with respect to the risks and benefits.

Displaying both the strategy that information analysis automation employs to makes its judgments and variability in the task environment may improve human judgment performance, especially in cases where this variability impacts the judgment performance of the information analysis automation. This work investigated the contribution of providing either information analysis automation strategy information, task environment information, or both, on human judgment performance in a domain where noisy sensor data are used by both the human and the information analysis automation to make judgments. In a simplified air traffic conflict prediction experiment, 32 participants made probability of horizontal conflict judgments under different display content conditions. After being exposed to the information analysis automation, judgment achievement significantly improved for all participants as compared to judgments without any of the automation's information. Participants provided with additional display content pertaining to cue variability in the task environment had significantly higher aided judgment achievement compared to those provided with only the automation's judgment of a probability of conflict. When designing information analysis automation for environments where the automation's judgment achievement is impacted by noisy environmental data, it may be beneficial to show additional task environment information to the human judge in order to improve judgment performance.

The purpose of this study was (a) to evaluate ten online periodic table sources for their accuracy and (b) to compare the types of information and links provided to users. Limited studies have been reported on online periodic table (Diener and Moore 2011; Slocum and Moore in J Chem Educ 86(10):1167, 2009). Chemistry students' understanding of periodic table is vital for their success in chemistry, and the online periodic table has the potential to advance learners' understanding of chemical elements and fundamental chemistry concepts (Brito et al. in J Res Sci Teach 42(1):84-111, 2005). The ten sites were compared for accuracy of data with the Handbook of Chemistry and Physics (HCP, Haynes in CRC handbook of chemistry and physics: a ready-reference book of chemical and physical data. CRC Press, Boca Raton 2012). The 10 sites are the most visited periodic table Web sites available. Four different elements, carbon, gold, argon, and plutonium, were selected for comparison, and 11 different attributes for each element were identified for evaluating accuracy. A wide variation of accuracy was found among the 10 periodic table sources. Chemicool was the most accurate information provider with 66.67 % accuracy when compared to the HCP. The 22 types of information including meaning of name and use in industry and society provided by these sites were, also, compared. WebElements, "Chemicool", "Periodic Table Live", and "the Photographic Periodic Table of the Elements" were the most information providers, providing 86.36 % of information among the 10 Web sites. "WebElements" provides the most links among the 10 Web sites. It was concluded that if an individual teacher or student desires only raw physical data from element, the Internet might not be the best choice.

Purpose Information about dementia is important for persons with dementia (PWD) and their caregivers and the Internet has become the key source of health information. We reviewed the content and quality of information provided on Canadian websites for Alzheimer’s disease (AD). Methods We used the terms “dementia” and “Alzheimer” in Google to identify Canadian dementia websites. The contents of websites were compared to 16 guideline recommendations provided in Canadian Consensus Conference on Diagnosis and Treatment of Dementia. The quality of information provided on websites was evaluated using the DISCERN instrument. The content and quality of information provided on selected websites were then described. Results Seven websites were identified, three of which provided relatively comprehensive and high-quality information on dementia. Websites frequently provided information about diagnosis of dementia, its natural course, and types of dementia, while other topics were less commonly addressed. The quality of information provided on the websites varied, and many websites had several areas where the quality of information provided was relatively low according to the DISCERN instrument. Conclusions There is variation in the content and quality of dementia websites, although some websites provide high-quality and relatively comprehensive information which would serve as a useful resource for PWD, caregivers, and healthcare providers. Improvements in the content and quality of information provided on AD websites would provide PWD and their caregivers with access to better information. PMID:23440180

The economics of comparative effectiveness studies: societal and private perspectives and their implications for prioritizing public investments in comparative effectiveness research.

PubMed

Meltzer, David; Basu, Anirban; Conti, Rena

2010-01-01

Comparative effectiveness research (CER) can provide valuable information for patients, providers and payers. These stakeholders differ in their incentives to invest in CER. To maximize benefits from public investments in CER, it is important to understand the value of CER from the perspectives of these stakeholders and how that affects their incentives to invest in CER. This article provides a conceptual framework for valuing CER, and illustrates the potential benefits of such studies from a number of perspectives using several case studies. We examine cases in which CER provides value by identifying when one treatment is consistently better than others, when different treatments are preferred for different subgroups, and when differences are small enough that decisions can be made based on price. We illustrate these findings using value-of-information techniques to assess the value of research, and by examining changes in pharmaceutical prices following publication of a comparative effectiveness study. Our results suggest that CER may have high societal value but limited private return to providers or payers. This suggests the importance of public efforts to promote the production of CER. We also conclude that value-of-information tools may help inform policy decisions about how much public funds to invest in CER and how to prioritize the use of available public funds for CER, in particular targeting public CER spending to areas where private incentives are low relative to social benefits.

Workload-Matched Adaptive Automation Support of Air Traffic Controller Information Processing Stages

NASA Technical Reports Server (NTRS)

Kaber, David B.; Prinzel, Lawrence J., III; Wright, Melanie C.; Clamann, Michael P.

2002-01-01

Adaptive automation (AA) has been explored as a solution to the problems associated with human-automation interaction in supervisory control environments. However, research has focused on the performance effects of dynamic control allocations of early stage sensory and information acquisition functions. The present research compares the effects of AA to the entire range of information processing stages of human operators, such as air traffic controllers. The results provide evidence that the effectiveness of AA is dependent on the stage of task performance (human-machine system information processing) that is flexibly automated. The results suggest that humans are better able to adapt to AA when applied to lower-level sensory and psychomotor functions, such as information acquisition and action implementation, as compared to AA applied to cognitive (analysis and decision-making) tasks. The results also provide support for the use of AA, as compared to completely manual control. These results are discussed in terms of implications for AA design for aviation.

2013-07-01

Comparing effectiveness of diagnostic tests is one of the highest priorities for comparative effectiveness research (CER) set by the Institute of Medicine. Our study aims to identify what information providers, payers and patients need from CER on diagnostics, and what challenges they encounter implementing comparative information on diagnostic alternatives in practice and policy. Using qualitative research methods and the example of two alternative protocols for HER2 testing in breast cancer, we conducted interviews with 45 stakeholders: providers (n = 25) from four academic and eight nonacademic institutions, executives (n = 13) from five major US private payers and representatives (n = 7) from two breast cancer patient advocacies. The need for additional scientific evidence to determine the preferred HER2 protocol was more common for advocates than payers (100 vs 54%; p = 0.0515) and significantly more common for advocates than providers (100 vs 40%; p = 0.0077). The availability of information allowing assessment of the implementation impact from alternative diagnostic protocols on provider institutions may mitigate the need for additional scientific evidence for some providers and payers (24 and 46%, respectively). The cost-effectiveness of alternative protocols from the societal perspective is important to payers and advocates (69 and 71%, respectively) but not to providers (0%; p = 0.0001 and p = 0.0001). The lack of reporting laboratory practices is a more common implementation challenge for payers and advocates (77 and 86%, respectively) than for providers (32%). The absence of any mechanism for patient involvement was recognized as a challenge by payers and advocates (69 and 100%, respectively) but not by providers (0%; p = 0.0001 and p = 0.0001). Comparative implementation research is needed to inform the stakeholders considering diagnostic alternatives. Transparency of laboratory practices is an important factor in enabling implementation of CER on diagnostics in practice and policy. The incongruent views of providers versus patient advocates and payers on involving patients in diagnostic decisions is a concerning challenge to utilizing the results of CER.

Client-provider interactions in provider-initiated and voluntary HIV counseling and testing services in Uganda

PubMed Central

2013-01-01

Background Provider-initiated HIV testing and counselling (PITC) is based on information-giving while voluntary counselling and testing (VCT) includes individualised client-centered counseling. It is not known if the provider-client experiences, perceptions and client satisfaction with the information provided differs in the two approaches. Methods In 2008, we conducted structured interviews with 627 individuals in Uganda; 301 tested through PITC and 326 through voluntary counselling and testing (VCT). We compared client experiences and perceptions based on the essential elements of consent, confidentiality, counseling, and referral for follow-up care. We conducted multivariate analysis for predictors of reporting information or counselling as sufficient. Results In VCT, 96.6% (282) said they were asked for consent compared to 91.3% (198) in PITC (P = 0.01). About the information provided, 92.0% (286) in VCT found it sufficient compared to 78.7% (221) in PITC (P = <0.01). In VCT 79.9% (246) thought their results were kept confidential compared to 71.7% (200) in PITC (P = 0.02). Eighty percent (64) of HIV infected VCT clients said they were referred for follow-up care versus 87.3% (48) in PITC (p = 0.2). Predictors of perceived adequacy of information in PITC included an opportunity to ask questions (adj.RR 1.76, CI 1.41, 2.18) and expecting the test results received (adj.RR 1.18, CI 1.06, 1.33). For VCT significant factors included being given an opportunity to ask questions (adj.RR 1.62, CI 1.00, 2.60) and 3+ prior times tested, (adj.RR 1.05, CI 1.00, 1.09). Conclusions This study demonstrates good practices in the essential elements of HIV testing for both VCT and PITC. However, further quality enhancement is required in both testing approaches in relation to referral to HIV care post-test, client confidence in relation to confidentiality, and providing an opportunity to ask questions to address client-specific information needs.

A randomized study was conducted to compare a generic and individualized approach to providing decisional support to men newly diagnosed with localized prostate cancer. Patients (N = 324) were referred by community urologists to a patient education center where they were randomly assigned to receive either an individualized or generic information intervention. Men assigned to the generic group viewed a video on the various treatments available for localized prostate cancer. Men in the individualized information group used a computer program to identify their information preferences. Computer printouts on top information preferences were individualized according to patient's specific disease characteristics, followed by a discussion of the pros and cons of each recommended treatment option. Both groups received a standardized package of written information. Men completed measures of decision control, satisfaction, and decision conflict at baseline and after a definitive treatment decision was made. Results demonstrated that overall both groups reported increased levels of decision control and lower levels of decision conflict after their treatment decision. All men reported being satisfied with their preparation to make a treatment decision. Compared to the generic information group, men who received the individualized information were more satisfied with the type, amount and method of providing information, and role played in treatment decision making with their physician (P < .002). Both information interventions seem to be similar in providing decisional support to this group of men at the time of diagnosis. Further research is required to determine how to identify men who may benefit from a more individualized approach.

Microtia and Social Media: Patient Versus Physician Perspective of Quality of Information.

PubMed

Sepehripour, Sarvnaz; McDermott, Ann Louise; Lloyd, Mark Sheldon

2017-05-01

Previous research demonstrates that patients seek high-quality information on the World Wide Web, especially in rare conditions such as microtia. Social media has overtaken other sources of patient information but quality remains untested. This study quantifies the quality of information for patients with Microtia on social media compared with nonsocial media websites and compares physician and patient scoring on quality using the DISCERN tool. In phase 1, quality of the top 100 websites featuring information "Microtia" was ranked according to quality score and position on Google showing the position of social media websites among other nonsocial media websites. Phase 2 involved independent scoring of websites on microtia compared with a patient group with microtia to test whether physicians score differently to patients with t test comparison. Social media websites account for 2% of the scored websites with health providers linking to social media. Social media websites were among the highest ranked on Google. No correlation was found between the quality of information and Google rank. Social media scored higher than nonsocial media websites regarding quality of information on microtia. No significant difference existed between physician and patient quality of information scores on social media and nonsocial media websites (p 1.033). Physicians and patients objectively score microtia websites alike. Social media websites have higher use despite being few in number compared with nonsocial media websites. Physicians providing links to social media on information websites on rare conditions such as microtia are engaging in current information-seeking trends.

Capturing the Surface Texture and Shape of Pollen: A Comparison of Microscopy Techniques

PubMed Central

Sivaguru, Mayandi; Mander, Luke; Fried, Glenn; Punyasena, Surangi W.

2012-01-01

Research on the comparative morphology of pollen grains depends crucially on the application of appropriate microscopy techniques. Information on the performance of microscopy techniques can be used to inform that choice. We compared the ability of several microscopy techniques to provide information on the shape and surface texture of three pollen types with differing morphologies. These techniques are: widefield, apotome, confocal and two-photon microscopy (reflected light techniques), and brightfield and differential interference contrast microscopy (DIC) (transmitted light techniques). We also provide a first view of pollen using super-resolution microscopy. The three pollen types used to contrast the performance of each technique are: Croton hirtus (Euphorbiaceae), Mabea occidentalis (Euphorbiaceae) and Agropyron repens (Poaceae). No single microscopy technique provided an adequate picture of both the shape and surface texture of any of the three pollen types investigated here. The wavelength of incident light, photon-collection ability of the optical technique, signal-to-noise ratio, and the thickness and light absorption characteristics of the exine profoundly affect the recovery of morphological information by a given optical microscopy technique. Reflected light techniques, particularly confocal and two-photon microscopy, best capture pollen shape but provide limited information on very fine surface texture. In contrast, transmitted light techniques, particularly differential interference contrast microscopy, can resolve very fine surface texture but provide limited information on shape. Texture comprising sculptural elements that are spaced near the diffraction limit of light (∼250 nm; NDL) presents an acute challenge to optical microscopy. Super-resolution structured illumination microscopy provides data on the NDL texture of A. repens that is more comparable to textural data from scanning electron microscopy than any other optical microscopy technique investigated here. Maximizing the recovery of morphological information from pollen grains should lead to more robust classifications, and an increase in the taxonomic precision with which ancient vegetation can be reconstructed.

Ranking sources of hospital quality information for orthopedic surgery patients: consequences for the system of managed competition.

PubMed

Bes, Romy Evelien; van den Berg, Bernard

2013-01-01

Healthcare quality information is crucial for the system of managed competition. Within a system of managed competition, health insurers can selectively contract care providers and are allowed to channel patients towards contracted providers. The idea is that insurers have a stronger bargaining position compared to care providers when they are able to channel patients. In the Dutch system of managed competition that was implemented in 2006, channelling patients to preferred providers has not yet been very successful. Empirical knowledge of which sources of hospital quality information they find important may help us to understand how to channel patients to preferred providers. The objective of this survey was to measure how patients rank various sources of information when they compare hospital quality in a system of managed competition. A written survey was conducted among clients of a large Dutch health insurance company. These clients underwent orthopedic surgery on the hip or knee no longer than 12 months ago. Two major players within a system of managed competition-health insurers and the government-were not seen as important sources of hospital quality information. In contrast, own experience and general practitioners (GPs) were seen as the most important sources of hospital quality information within the Dutch system of managed competition. Health insurers should take the main finding-that GPs are the most important source of hospital quality information-into account when they contract care providers and develop strategies for channeling patients towards preferred providers. A well-functioning system of managed competition will benefit patients, as it involves incentives for care providers to increase healthcare quality and to produce at the lowest cost per unit of quality.

Transparency of Mandatory Information Disclosure and Concerns of Health Services Providers and Consumers.

Yan, Yu-Hua; Kung, Chih-Ming; Fang, Shih-Chieh; Chen, Yi

2017-01-09

This study analyzed differences between transparency of information disclosure and related demands from the health service consumer's perspective. It also compared how health service providers and consumers are associated by different levels of mandatory information disclosure. We obtained our research data using a questionnaire survey (health services providers, n = 201; health service consumers, n = 384). Health service consumers do not have major concerns regarding mandatory information disclosure. However, they are concerned about complaint channels and settlement results, results of patient satisfaction surveys, and disclosure of hospital financial statements ( p < 0.001). We identified significant differences in health service providers' and consumers' awareness regarding the transparency of information disclosure ( p < 0.001). It may not be possible for outsiders to properly interpret the information provided by hospitals. Thus, when a hospital discloses information, it is necessary for the government to consider the information's applicability. Toward improving medical expertise and information asymmetry, the government has to reduce the burden among health service consumers in dealing with this information, and it has to use the information effectively.

[The obligation to inform the patient: issues on the right to be informed].

PubMed

Parra S, Darío

2013-12-01

This article aims to analyze, from a legal perspective, the boundaries of the obligation imposed on health care providers to inform the patient. This requirement originated and was developed as an ethical issue. However, with the newly approved law regulating the rights and duties of patients, the obligation to inform can be viewed from prisms and principles that differ from those governing medical ethics. With this purpose, we will focus on the comparative experience, which will allow us to evaluate the responsibility of health care providers when this duty is breached. We will try to answer the following questions: Which medical information must be informed to the patient? When should the doctor inform the patient? In which form should this information be provided?.

Variation In Rural Health Information Technology Adoption And Use.

PubMed

Heisey-Grove, Dawn M

2016-02-01

While rural hospitals and physicians have adopted health information technology at the same, or greater, rates as their urban counterparts, meaningful-use attestation varies dramatically among rural providers. Also, rural providers are more likely to skip a year of declaring that they have met meaningful-use requirements, putting them at a financial disadvantage compared to urban providers.

Study objectives We aimed to investigate how different presentation formats influence comprehension and use of comparative performance information (CPI) among consumers. Methods An experimental between-subjects and within-subjects design with manipulations of CPI presentation formats. We enrolled both consumers with lower socioeconomic status (SES)/cognitive skills and consumers with higher SES/cognitive skills, recruited through an online access panel. Respondents received fictitious CPI and completed questions about interpretation and information use. Between subjects, we tested (1) displaying an overall performance score (yes/no); (2) displaying a small number of quality indicators (5 vs 9); and (3) displaying different types of evaluative symbols (star ratings, coloured dots and word icons vs numbers and bar graphs). Within subjects, we tested the effect of a reduced number of healthcare providers (5 vs 20). Data were analysed using descriptive analysis, analyses of variance and paired-sampled t tests. Results A total of 902 (43%) respondents participated. Displaying an overall performance score and the use of coloured dots and word icons particularly enhanced consumer understanding. Importantly, respondents provided with coloured dots most often correctly selected the top three healthcare providers (84.3%), compared with word icons (76.6% correct), star ratings (70.6% correct), numbers (62.0%) and bars (54.2%) when viewing performance scores of 20 providers. Furthermore, a reduced number of healthcare providers appeared to support consumers, for example, when provided with 20 providers, 69.5% correctly selected the top three, compared with 80.2% with five providers. Discussion Particular presentation formats enhanced consumer understanding of CPI, most importantly the use of overall performance scores, word icons and coloured dots, and a reduced number of providers displayed. Public report efforts should use these formats to maximise impact on consumers. PMID:26543066

The objective of this work was to assess the functional utility of new display concepts for an emergency department information system created using cognitive systems engineering methods, by comparing them to similar displays currently in use. The display concepts were compared to standard displays in a clinical simulation study during which nurse-physician teams performed simulated emergency department tasks. Questionnaires were used to assess the cognitive support provided by the displays, participants’ level of situation awareness, and participants’ workload during the simulated tasks. Participants rated the new displays significantly higher than the control displays in terms of cognitive support. There was no significant difference in workload scores between the display conditions. There was no main effect of display type on situation awareness, but there was a significant interaction; participants using the new displays showed improved situation awareness from the middle to the end of the session. This study demonstrates that cognitive systems engineering methods can be used to create innovative displays that better support emergency medicine tasks, without increasing workload, compared to more standard displays. These methods provide a means to develop emergency department information systems—and more broadly, health information technology—that better support the cognitive needs of healthcare providers.

Inter-informant agreement and prevalence estimates for mood syndromes: direct interview vs. family history method.

PubMed

Vandeleur, C L; Rothen, S; Lustenberger, Y; Glaus, J; Castelao, E; Preisig, M

2015-01-15

The use of the family history method is recommended in family studies as a type of proxy interview of non-participating relatives. However, using different sources of information can result in bias as direct interviews may provide a higher likelihood of assigning diagnoses than family history reports. The aims of the present study were to: (1) compare diagnoses for threshold and subthreshold mood syndromes from interviews to those relying on information from relatives; (2) test the appropriateness of lowering the diagnostic threshold and combining multiple reports from the family history method to obtain comparable prevalence estimates to the interviews; (3) identify factors that influence the likelihood of agreement and reporting of disorders by informants. Within a family study, 1621 informant-index subject pairs were identified. DSM-5 diagnoses from direct interviews of index subjects were compared to those derived from family history information provided by their first-degree relatives. (1) Inter-informant agreement was acceptable for Mania, but low for all other mood syndromes. (2) Except for Mania and subthreshold depression, the family history method provided significantly lower prevalence estimates. The gap improved for all other syndromes after lowering the threshold of the family history method. (3) Individuals who had a history of depression themselves were more likely to report depression in their relatives. Low proportion of affected individuals for manic syndromes and lack of independence of data. The higher likelihood of reporting disorders by affected informants entails the risk of overestimation of the size of familial aggregation of depression. Copyright © 2014 Elsevier B.V.

Gennery, Donald B. (Inventor)

1987-01-01

Digital values in a moving window are compared by an operator having nine comparators (18) connected to line buffers (16) for receiving a succession of central pixels together with eight neighborhood pixels. A single bit of program control determines whether the neighborhood pixels are to be compared with the central pixel or a threshold value. The central pixel is always compared with the threshold. The comparator output, plus 2 bits indicating odd-even pixel/line information about the central pixel, addresses a lookup table (20) to provide 14 bits of information, including 2 bits which control a selector (22) to pass either the central pixel value, the other 12 bits of table information, or the bit-wise logic OR of all neighboring pixels.

A framework for characterizing drug information sources.

PubMed

Sharp, Mark; Bodenreider, Olivier; Wacholder, Nina

2008-11-06

Drug information is complex, voluminous, heterogeneous, and dynamic. Multiple sources are available, each providing some elements of information about drugs (usually for a given purpose), but there exists no integrated view or directory that could be used to locate sources appropriate to a given purpose. We examined 23 sources that provide drug information in the pharmacy, chemistry, biology, and clinical medicine domains. Their drug information content could be categorized with 39 dimensions. We propose this list of dimensions as a framework for characterizing drug information sources. As an evaluation, we show that this framework is useful for comparing drug information sources and selecting sources most relevant to a given use case.

Comparing hospital staff and patient perceptions of customer service: a pilot study utilizing survey and focus group data.

PubMed

Fottler, Myron D; Dickson, Duncan; Ford, Robert C; Bradley, Kenneth; Johnson, Lee

2006-02-01

The measurement of patient satisfaction is crucial to enhancing customer service and competitive advantage in the health-care industry. While there are numerous approaches to such measurement, this paper provides a case study which compares and contrasts patient and staff perceptions of customer service using both survey and focus group data. Results indicate that there is a high degree of correlation between staff and patient perceptions of customer service based on both survey and focus group data. However, the staff and patient subgroups also provided complementary information regarding patient perceptions of their service experience. Staff members tended to have more negative perceptions of service attributes than did the patients themselves. The focus group results provide complementary information to survey results in terms of greater detail and more managerially relevant information. While these results are derived from a pilot study, they suggest that diversification of data sources beyond patient surveys may enhance the utility of customer service information. If further research can affirm these findings, they create exciting possibilities for gathering valid, reliable and cost-effective customer service information.

This study investigates whether applying educational testing approaches to an informed consent video for a medical procedure can lead to greater recall of the information presented. Undergraduate students (n=120) were randomly assigned to watch a 20-min video on informed consent under one of three conditions: 1) tested using multiple-choice knowledge questions and provided with feedback on their answers after each 5-min segment; 2) tested with multiple choice knowledge questions but not provided feedback after each segment; or 3) watched the video without knowledge testing. Participants who were tested and provided feedback had significantly greater information recall compared to those who were tested but not provided feedback and to those not tested. The effect of condition was stronger for moderately difficult questions versus easy questions. Inserting knowledge tests and providing feedback about the responses at timed intervals in videos can be effective in improving recall of information. Providing informed consent information through a video not only standardizes the material, but using testing with feedback inserted within the video has the potential to increase recall and retention of this material.

Medicines information provided by pharmaceutical representatives: a comparative study in Australia and Malaysia

PubMed Central

2010-01-01

Background Pharmaceutical representatives provide medicines information on their promoted products to doctors. However, studies have shown that the quality of this information is often low. No study has assessed the medicines information provided by pharmaceutical representatives to doctors in Malaysia and no recent evidence in Australia is present. We aimed to compare the provision of medicines information by pharmaceutical representatives to doctors in Australia and Malaysia. Methods Following a pharmaceutical representative's visit, general practitioners in Australia and Malaysia who had agreed to participate, were asked to fill out a questionnaire on the main product and claims discussed during the encounter. The questionnaire focused on provision of product information including indications, adverse effects, precautions, contraindications and the provision of information on the Pharmaceutical Benefit Scheme (PBS) listings and restrictions (in Australia only). Descriptive statistics were produced. Chi-square analysis and clustered linear regression were used to assess differences in Australia and Malaysia. Results Significantly more approved product information sheets were provided in Malaysia (78%) than in Australia (53%) (P < 0.001). In both countries, general practitioners reported that indications (Australia, 90%, Malaysia, 93%) and dosages (Australia, 76%, Malaysia, 82%) were frequently provided by pharmaceutical representatives. Contraindications, precautions, drug interactions and adverse effects were often omitted in the presentations (range 25% - 41%). General practitioners in Australia and Malaysia indicated that in more than 90% of presentations, pharmaceutical representatives partly or fully answered their questions on contraindications, precautions, drug interactions and adverse effects. More general practitioners in Malaysia (85%) than in Australia (60%) reported that pharmaceutical representatives should have mentioned contraindications, precautions for use, drug interaction or adverse effects spontaneously (P < 0.001). In 48% of the Australian presentations, general practitioners reported the pharmaceutical representatives failed to mention information on PBS listings to general practitioners. Conclusions Information on indications and dosages were usually provided by pharmaceutical representatives in Australia and Malaysia. However, risk and harmful effects of medicines were often missing in their presentations. Effective control of medicines information provided by pharmaceutical representatives is needed.

How visual timing and form information affect speech and non-speech processing.

PubMed

Kim, Jeesun; Davis, Chris

2014-10-01

Auditory speech processing is facilitated when the talker's face/head movements are seen. This effect is typically explained in terms of visual speech providing form and/or timing information. We determined the effect of both types of information on a speech/non-speech task (non-speech stimuli were spectrally rotated speech). All stimuli were presented paired with the talker's static or moving face. Two types of moving face stimuli were used: full-face versions (both spoken form and timing information available) and modified face versions (only timing information provided by peri-oral motion available). The results showed that the peri-oral timing information facilitated response time for speech and non-speech stimuli compared to a static face. An additional facilitatory effect was found for full-face versions compared to the timing condition; this effect only occurred for speech stimuli. We propose the timing effect was due to cross-modal phase resetting; the form effect to cross-modal priming. Copyright © 2014 Elsevier Inc. All rights reserved.

Federal and state nursing facility websites: just what the consumer needs?

Harrington, Charlene; Collier, Eric; O'Meara, Janis; Kitchener, Martin; Simon, Lisa Payne; Schnelle, John F

2003-01-01

Since the introduction of the Medicare Nursing Home Compare website in 1999, some states have begun to develop their own websites to help consumers compare nursing facilities (NFs). This article presents a brief conceptual framework for the type of information needed for an Internet-based information system and analyzes existing federal and state NF websites, using data collected from a survey completed in 2002. Twenty-four states and the District of Columbia have a variety of information on NFs, similar to the information on the Medicare website. Information on characteristics and deficiencies of a facility is the most commonly available, but a few states have data on ownership, staffing indicators, quality indicators, complaints, and enforcement actions. Other types of data, such as resident characteristics, staff turnover rates, and financial indicators, are generally not available. Although many states are making progress toward providing consumers with information, there are gaps that exist, which if filled, could provide consumers with a better tool for facility selection and monitoring the quality of care.

How do physicians provide statistical information about antidepressants to hypothetical patients?

Gaissmaier, Wolfgang; Anderson, Britta L; Schulkin, Jay

2014-02-01

Little is known about how physicians provide statistical information to patients, which is important for informed consent. In a survey, obstetricians and gynecologists (N = 142) received statistical information about the benefit and side effects of an antidepressant. They received information in various formats, including event rates (antidepressant v. placebo), absolute risks, and relative risks. Participants had to imagine 2 hypothetical patients, 1 for whom they believed the drug to be safe and effective and 1 for whom they did not, and select the information they would give those patients. We assessed whether the information they selected for each patient was complete, transparent, interpretable, or persuasive (i.e., to nudge patients toward a particular option) and compared physicians who gave both patients the same information with those who gave both patients different information. A similar proportion of physicians (roughly 25% each) selected information that was 1) complete and transparent, 2) complete but not transparent, 3) not interpretable for the patient because necessary comparative information was missing, or 4) suited for nudging. Physicians who gave both patients the same information (61% of physicians) more often selected at least complete information, even if it was often not transparent. Physicians who gave both patients different information (39% of physicians), in contrast, more often selected information that was suited for nudging in line with the belief they were asked to imagine. A limitation is that scenarios were hypothetical. Most physicians did not provide complete and transparent information. Clinicians who presented consistent information to different patients tended to present complete information, whereas those who varied what information they chose to present appeared more prone to nudging.

Land managers need cost-effective and informative tools for non-native plant species management. Many local, state, and federal agencies adopted mapping systems designed to collect comparable data for the early detection and monitoring of non-native species. We compared mapping information to statistically rigorous, plot-based methods to better understand the benefits and compatibility of the two techniques. Mapping non-native species locations provided a species list, associated species distributions, and infested area for subjectively selected survey sites. The value of this information may be compromised by crude estimates of cover and incomplete or biased estimations of species distributions. Incorporating plot-based assessments guided by a stratified-random sample design provided a less biased description of non-native species distributions and increased the comparability of data over time and across regions for the inventory, monitoring, and management of non-native and native plant species.

Radiation therapy for people with cancer: what do written information materials tell them?

PubMed

Smith, S K; Yan, B; Milross, C; Dhillon, H M

2016-07-01

This study aimed to compare and contrast the contents of different types of written patient information about radiotherapy, namely (1) hospital radiotherapy departments vs. cancer control organisations and (2) generic vs. tumour-specific materials. A coding framework, informed by existing patients' information needs literature, was developed and applied to 54 radiotherapy information resources. The framework comprised 12 broad themes; cancer diagnosis, general information about radiotherapy, treatment planning, daily treatment, side effects, self-care management, external radiotherapy, internal radiotherapy, impact on daily activities, post-treatment, psychosocial health and other content, such as a glossary. Materials produced by cancer organisations contained significantly more information than hospital resources on diagnosis, general radiotherapy information, internal radiotherapy and psychosocial health. However, hospital materials provided more information about treatment planning, daily treatment and the impact on daily activities. Compared to generic materials, tumour-specific resources were superior in providing information about diagnosis, daily treatment, side effects, post-treatment and psychosocial health. Information about internal radiotherapy, prognosis and chronic side effects were poorly covered by most resources. Collectively, hospital and cancer organisation resources complement each other in meeting patients' information needs. Identifying ways to consolidate different information sources could help comprehensively address patients' medical and psychosocial information needs about radiotherapy. © 2015 John Wiley & Sons Ltd.

Transparency of Mandatory Information Disclosure and Concerns of Health Services Providers and Consumers

Yan, Yu-Hua; Kung, Chih-Ming; Fang, Shih-Chieh; Chen, Yi

2017-01-01

Background: This study analyzed differences between transparency of information disclosure and related demands from the health service consumer’s perspective. It also compared how health service providers and consumers are associated by different levels of mandatory information disclosure. Methods: We obtained our research data using a questionnaire survey (health services providers, n = 201; health service consumers, n = 384). Results: Health service consumers do not have major concerns regarding mandatory information disclosure. However, they are concerned about complaint channels and settlement results, results of patient satisfaction surveys, and disclosure of hospital financial statements (p < 0.001). We identified significant differences in health service providers’ and consumers’ awareness regarding the transparency of information disclosure (p < 0.001). Conclusions: It may not be possible for outsiders to properly interpret the information provided by hospitals. Thus, when a hospital discloses information, it is necessary for the government to consider the information’s applicability. Toward improving medical expertise and information asymmetry, the government has to reduce the burden among health service consumers in dealing with this information, and it has to use the information effectively.

2016-12-01

Comparison of provider performance is commonly used to inform health care decision-making. Little attention has been paid to how data presentations influence decisions. This study analyzes differences in suggested actions by decision-makers informed by league tables or funnel plots. Decision-makers were invited to a survey and randomized to compare hospital performance using either league tables or funnel plots for four different measures within the area of cancer care. For each measure, decision-makers were asked to suggest actions towards 12-16 hospitals (no action, ask for more information, intervene) and provide feedback related to whether the information provided had been useful. Swedish health care. Two hundred and twenty-one decision-makers at administrative and clinical levels. Data presentations in the form of league tables or funnel plots. Number of actions suggested by participants. Proportion of appropriate actions. For all four measures, decision-makers tended to suggest more actions based on the information provided in league tables compared to funnel plots (44% vs. 21%, P < 0.001). Actions were on average more appropriate for funnel plots. However, when using funnel plots, decision-makers more often missed to react even when appropriate. The form of data presentation had an influence on decision-making. With league tables, decision-makers tended to suggest more actions compared to funnel plots. A difference in sensitivity and specificity conditioned by the form of presentation could also be identified, with different implications depending on the purpose of comparisons. Explanations and visualization aids are needed to support appropriate actions. © The Author 2016.

Beyond the verbal: Pregnant women's preferences for receiving influenza and Tdap vaccine information from their obstetric care providers.

PubMed

Ellingson, Mallory; Chamberlain, Allison T

2018-03-04

Prenatal providers are pregnant women's most trusted sources of health information, and a provider's recommendation is a strong predictor of maternal vaccine receipt. However, other ways women prefer receiving vaccine-related information from prenatal providers, aside from face-to-face conversations, is unclear. This study explores what secondary communication methods are preferred for receiving maternal vaccine-related information. Obstetric patients at four prenatal clinics around Atlanta, Georgia received a 27-item survey between May 5th, 2016 and June 15th, 2016. Participants were asked about sources they currently use to obtain prenatal health information and their preferences for receiving vaccine-related information from providers. Descriptive statistics were calculated and chi-square tests were used to evaluate associations between participant characteristics and outcomes. Women primarily reported using the CDC website (57.7%) and pregnancy-related websites (53.0%) to obtain vaccine information. Apart from clinical conversations, educational brochures (64.9%) and e-mails (54.7%) were the preferred methods of receiving vaccine information from providers, followed by their provider's practice website (42.1%). Communication preferences and interest in maternal immunization varied by race/ethnicity, age and education; white women were twice as likely to want information on a provider's practice website compared to African-American women (OR = 2.06; 95% CI: 1.31, 3.25). Pregnant women use the Internet for information about vaccines, but they still value input from their providers. While e-mails and brochures were the preferred secondary modes of receiving information, a provider's existing practice website offers a potential communications medium that capitalizes on women's information seeking behaviors and preferences while limiting burden on providers.

Presence of nursing information on hospital websites in five countries: a review.

PubMed

Chen, L L; Liu, Y L

2010-06-01

The aims of this study were to (1) examine the presence of nursing information on 50 hospital websites across five countries; (2) describe the accessibility, range and depth of nursing information provided; and (3) compare the characteristics of nursing web information across the countries. Providing information on hospital website is an increasingly popular strategy for marketing hospital services, and it has been playing unique and important roles for nursing. So far, the nursing information offered via hospital websites is not uncommon worldwide, but the amount, content and form of such information presented by the institutions of different countries have not been examined systematically. Objective sampling was employed to select 50 top hospital websites from five countries, with ten for each geographical region, namely, Australia (Oceania), China (Asia), South Africa (Africa), UK (Europe) and the USA (North America). A self-developed checklist was used to examine the presence of nursing information on the above-mentioned hospital websites. The most frequently presented information on the hospital websites was nursing employment (job placement), nursing education, and news and events concerning the nursing profession, but information about other aspects of nursing was relatively lacking. The hospital websites in the USA and Australia provided more information as compared with those in China and the UK. Nursing information was almost unavailable on hospital websites in South Africa. Although the accessibility of nursing-related information has been improved, the presence of nursing information was not strong on the hospital websites across the five countries. The nursing information presented on hospital websites varied with different countries. Efforts have to be made to improve the presence and accessibility of nursing information. Information about the nursing services, professional image of nurses and nursing employment should be enhanced.

Jun, Jungmi; Nan, Xiaoli

2018-05-01

This research examined (1) smokeless tobacco users' comparative optimism in assessing the health and addiction risks of their own product in comparison with cigarettes, and (2) the effects of comparative optimism on cessation information-seeking. A nationally-representative sample from the 2015 Health Information National Trends Survey (HINTS)-FDA was employed. The analyses revealed the presence of comparative optimism in assessing both health and addiction risks among smokeless tobacco users. Comparative optimism was negatively correlated with most cessation information-seeking variables. Health bias (the health risk rating gap between the subject's own tobacco product and cigarettes) was associated with decreased intent to use cessation support. However, the health bias and addiction bias (the addiction risk rating gap between the subject's own tobacco product and cigarettes) were not consistent predictors of all cessation information-seeking variables, when covariates of socio-demographics and tobacco use status were included. In addition, positive correlations between health bias and past/recent cessation-information searches were observed. Optimisic biases may negatively influence cessation behaviors not only directly but also indirectly by influencing an important moderator, cessation information-seeking. Future interventions should prioritize dispelling the comparative optimism in perceiving risks of smokeless tobacco use, as well as provide more reliable cessation information specific to smokeless tobacco users.

The importance of the Internet as a medium for publishing and sharing health and medical information has increased considerably during the last decade. Nonetheless, comprehensive knowledge and information are scarce and difficult to find, especially for rare diseases. Additionally, the quality of health or medical information about rare diseases is frequently difficult to assess for the patients and their family members. The aim of this study is to assess the quality of information on the Internet about rare diseases. Additionally, the study aims to evaluate if the quality of information on rare diseases varies between different information supplier categories. A total of 13 quality criteria for websites providing medical information about rare diseases were transferred to a self-disclosure questionnaire. Identified providers of information on the Internet about rare diseases were invited to fill out the questionnaire. The questionnaire contained questions about the information provider in general (eg, supplier category, information category, language, use of quality certificates, and target group) and about quality aspects that reflect the 13 quality criteria. Differences in subgroup analyses were performed using t tests. We identified 693 websites containing information about rare diseases. A total of 123 questionnaires (17.7%) were completely filled out by the information suppliers. For the remaining identified suppliers (570/693, 82.3%), the questionnaires were filled out by the authors based on the information available on their website. In many cases, the quality of websites was proportionally low. Furthermore, subgroup analysis showed no statistically significant differences between the quality of information provided by support group/patient organization compared to medical institution (P=.19). The quality of information by individuals (patient/relative) was significantly lower compared to information provided by support group/patient organization (P=.001), medical institution (P=.009), and other associations and sponsoring bodies (P=.001) as well. Overall, the quality of information on the Internet about rare diseases is low. Quality certificates are rarely used and important quality criteria are often not fulfilled completely. Additionally, some information categories are underrepresented (eg, information about psychosocial counseling, social-legal advice, and family planning). Nevertheless, due to the high amount of information provided by support groups, this study shows that these are extremely valuable sources of information for patients suffering from a rare disease and their relatives. ©Frédéric Pauer, Svenja Litzkendorf, Jens Göbel, Holger Storf, Jan Zeidler, Johann-Matthias Graf von der Schulenburg.

Comics as a Medium for Providing Information on Adult Immunizations.

PubMed

Muzumdar, Jagannath M; Pantaleo, Nicholas L

2017-10-01

This study compared the following effects of two vaccine information flyers-one developed by the Centers for Disease Control and Prevention (CDC) versus one adapted from this information to a comic medium (comic)-on adults: (a) attitude toward the flyer; (b) perceived informativeness of the flyer; (c) intention to seek more information about adult immunizations after viewing the flyer; and (d) intention to get immunized after viewing the flyer. A between-group, randomized trial was used to randomly assign adults (age 18 years or older) at an ambulatory care center to review the CDC or comic flyer. Participants were asked to complete a survey to measure several outcome variables. Items were measured using a 7-point semantic differential scale. Independent-samples t-test was used for comparisons. A total of 265 surveys (CDC n = 132 vs comic n = 133) were analyzed. The comic flyer had a statistically significant effect on participants' attitudes and their perception of the flyer's informativeness compared to the CDC flyer. Flyer type did not have a statistically significant effect on intention-related variables. The study findings showed that the comic flyer was positively evaluated compared to the CDC flyer. These findings could provide a new direction for developing adult educational materials.

Driving toward guiding principles: a goal for privacy, confidentiality, and security of health information.

Buckovich, S A; Rippen, H E; Rozen, M J

1999-01-01

As health care moves from paper to electronic data collection, providing easier access and dissemination of health information, the development of guiding privacy, confidentiality, and security principles is necessary to help balance the protection of patients' privacy interests against appropriate information access. A comparative review and analysis was done, based on a compilation of privacy, confidentiality, and security principles from many sources. Principles derived from ten identified sources were compared with each of the compiled principles to assess support level, uniformity, and inconsistencies. Of 28 compiled principles, 23 were supported by at least 50 percent of the sources. Technology could address at least 12 of the principles. Notable consistencies among the principles could provide a basis for consensus for further legislative and organizational work. It is imperative that all participants in our health care system work actively toward a viable resolution of this information privacy debate.

Sexual information seeking is an important element within human information behavior. Seeking sexually related information on the Internet takes many forms and channels, including chat rooms discussions, accessing Websites or searching Web search engines for sexual materials. The study of sexual Web queries provides insight into sexually-related information-seeking behavior, of value to Web users and providers alike. We qualitatively analyzed queries from logs of 1,025,910 Alta Vista and AlltheWeb.com Web user queries from 2001. We compared the differences in sexually-related Web searching between Alta Vista and AlltheWeb.com users. Differences were found in session duration, query outcomes, and search term choices. Implications of the findings for sexual information seeking are discussed.

Pharmacist, general practitioner and consumer use of written medicine information in Australia: are they on the same page?

PubMed

Hamrosi, Kim K; Raynor, David K; Aslani, Parisa

2014-01-01

Providing written medicine information to consumers enables them to make informed decisions about their medicines, playing an important role in educating and improving health literacy. In Australia, standardized written medicine information called Consumer Medicine Information (CMI) is available for medicines as package inserts, computer prints, or leaflets. Consumers want and read CMI, but may not always ask for it. General practitioners (GPs) and pharmacists are an important source of written medicine information, yet may not always provide CMI in their practice. To examine and compare the awareness, use and provision of CMI by consumers, pharmacists and general practitioners (GPs). Based on previous studies, structured questionnaires were developed and administered to a national sample of consumers (phone survey); community pharmacists and GPs (postal surveys) about utilization of CMI. Descriptive, comparative and logistic regression analyses were conducted. The respondents comprised of 349 pharmacists, 181 GPs and 1000 consumers. Two-thirds of consumers, nearly all (99%) pharmacists and 90% of GPs were aware of CMI. About 88% of consumers reported receiving CMI as a package insert, however most pharmacists (99%) and GPs (56%) reported providing computer-generated CMI. GPs' and pharmacists' main reason for providing CMI was on patient request. Reasons for not providing were predominantly because consumers were already taking the medicine, concerns regarding difficulty understanding the information, or potential non-adherence. Of the 691 consumers reportedly reading CMI, 35% indicated concerns after reading. Factors associated with reading included gender, type of CMI received and frequency of provision. Consumers want and read information about their medicines, especially when received from their GP or pharmacist. Healthcare professionals report usually discussing CMI when providing it to patients, although continued improvements in dissemination rates are desirable. Regular use of CMI remains a challenge, and ongoing strategies to promote CMI use are necessary to improve uptake of CMI in Australia. Copyright © 2014 Elsevier Inc. All rights reserved.

Online sperm donors: the impact of family, friends, personality and risk perception on behaviour.

Whyte, Stephen; Savage, David A; Torgler, Benno

2017-12-01

As informal sperm donation becomes more prevalent worldwide, understanding donor psychology and interactions is critical in providing effective policy, equitable legislative frameworks and frontline health support to an ever-growing number of global participants. We analyse data of informal sperm donors who were members of the connection website PrideAngel to identify the role and effect of several factors, e.g. kinship, social networks, personality, and risk perception, on behaviour. A key strength of the study is the ability to analyse various factors, such as the level and history of informal donation, risk concerns, number of women to whom donations are informally made and the number of offspring. Our results indicate donors who have also been active in formal clinical settings (compared with those who exclusively donate informally), donate to more women in the informal market and realise more offspring. Donor's sexual orientation also affects activity. From a personality perspective, conscientiousness provides comparative advantage. It is possible this characteristic provides positive externalities, as more conscientious men may be more efficient or organised in a market that requires increased cooperation and communication. The importance of kin and social networks seems to affect frequency of donation only, possibly representing a time constraint (or opportunity cost). Copyright © 2017 Reproductive Healthcare Ltd.

2015-02-06

Rapid diagnostic tests (RDTs) for malaria enable proper diagnosis and have been shown to reduce overuse of artemisinin combination therapy. Few studies have evaluated the feasibility and use of RDTs in the private sector in Myanmar. The objectives of the study were to: 1) understand the acceptability of using RDTs in the informal sector in Myanmar; 2) examine motivations for use among informal providers; and, 3) highlight decision-making and knowledge of providers for diagnostic testing and treatment. Qualitative interviews were conducted with 30 informal providers. Purposeful sampling was used to enrol study participants in the Mon and Shan State in Myanmar. All interviews were conducted in Burmese, translated into English, and two researchers coded all interviews using Atlas ti. Major themes identified included: 1) informal provider and outlet characteristics, including demographic and background characteristics; 2) the benefits and challenges of using RDTs according to providers; 3) provider experiences with using RDTs, including motivations for using the RDT; 4) adherence to test results, either positive or negative; and, 5) recommendations from informal providers to promote increased use of RDTs in their communities. This study found that introducing RDTs to informal providers in Myanmar was feasible, resulting in improved provider empowerment and patient-provider relationships. Specific challenges included facility infrastructure to use and dispose RDTs and provider knowledge. This varied across the type of informal provider, with itinerant drug vendors more comfortable and knowledgeable about RDTs compared to general retail sellers and medical drug representatives. This study found informal providers in Myanmar found the introduction of RDTs to be highly acceptable. Providers discussed improvement in service quality including provider empowerment and patient-provider relationships. The study also highlighted a number of challenges that informal providers face which may be used for future development of interventions.

2015-01-01

Different groups of audiences in health care: health professionals and health consumers, each have different information needs. Health monographs targeting different audiences are created by leveraging readers' background knowledge. The NCI's Physician Data Query (PDQ®) Cancer Information Summaries provide parallel cancer information and education resources with different target audiences. In this paper, we used targeted audience-specific cancer information PDQs to measure characteristic differences on the element level between audiences. In addition, we compared vocabulary coverage. Results show a significant difference between the professional and patient version of cancer monographs in both content organization and vocabulary. This study provides a new view to assess targeted audience-specific health information, and helps editors to improve the quality and readability of health information.

An Informative Interpretation of Decision Theory: The Information Theoretic Basis for Signal-to-Noise Ratio and Log Likelihood Ratio

DOE PAGES

Polcari, J.

2013-08-16

The signal processing concept of signal-to-noise ratio (SNR), in its role as a performance measure, is recast within the more general context of information theory, leading to a series of useful insights. Establishing generalized SNR (GSNR) as a rigorous information theoretic measure inherent in any set of observations significantly strengthens its quantitative performance pedigree while simultaneously providing a specific definition under general conditions. This directly leads to consideration of the log likelihood ratio (LLR): first, as the simplest possible information-preserving transformation (i.e., signal processing algorithm) and subsequently, as an absolute, comparable measure of information for any specific observation exemplar. Furthermore,more » the information accounting methodology that results permits practical use of both GSNR and LLR as diagnostic scalar performance measurements, directly comparable across alternative system/algorithm designs, applicable at any tap point within any processing string, in a form that is also comparable with the inherent performance bounds due to information conservation.« less

Preoperative assessment of intracranial tumors with perfusion MR and a volumetric interpolated examination: a comparative study with DSA.

2002-01-01

In evaluating intracranial tumors, a safe low-cost alternative that provides information similar to that of digital subtraction angiography (DSA) may be of interest. Our purpose was to determine the utility and limitations of a combined MR protocol in assessing (neo-) vascularity in intracranial tumors and their relation to adjacent vessels and to compare the results with those of DSA. Twenty-two consecutive patients with an intracranial tumor who underwent preoperative stereoscopic DSA were examined with contrast-enhanced dynamic T2*-weighted perfusion MR imaging followed by a T1-weighted three-dimensional (3D) MR study (volumetric interpolated brain examination [VIBE]). The maximum relative cerebral blood volume (rCBV) of the tumor was compared with tumor vascularity at DSA. Critical vessel structures were defined in each patient, and VIBE images of these structures were compared with DSA findings. For full exploitation of the 3D data sets, maximum-intensity projection algorithms reconstructed in real time with any desired volume and orientation were used. Tumor blush scores at DSA were significantly correlated with the rCBV measurements (r = 0.75; P <.01, Spearman rank correlation coefficient). In 17 (77%) patients, VIBE provided all relevant information about the venous system, whereas information about critical arteries were partial in 50% of the cases and not relevant in the other 50%. A fast imaging protocol consisting of perfusion MR imaging and a volumetric MR acquisition provides some of the information about tumor (neo-) vascularity and adjacent vascular anatomy that can be obtained with conventional angiography. However, the MR protocol provides insufficient visualization of distal cerebral arteries.

We aimed to investigate how different presentation formats influence comprehension and use of comparative performance information (CPI) among consumers. An experimental between-subjects and within-subjects design with manipulations of CPI presentation formats. We enrolled both consumers with lower socioeconomic status (SES)/cognitive skills and consumers with higher SES/cognitive skills, recruited through an online access panel. Respondents received fictitious CPI and completed questions about interpretation and information use. Between subjects, we tested (1) displaying an overall performance score (yes/no); (2) displaying a small number of quality indicators (5 vs 9); and (3) displaying different types of evaluative symbols (star ratings, coloured dots and word icons vs numbers and bar graphs). Within subjects, we tested the effect of a reduced number of healthcare providers (5 vs 20). Data were analysed using descriptive analysis, analyses of variance and paired-sampled t tests. A total of 902 (43%) respondents participated. Displaying an overall performance score and the use of coloured dots and word icons particularly enhanced consumer understanding. Importantly, respondents provided with coloured dots most often correctly selected the top three healthcare providers (84.3%), compared with word icons (76.6% correct), star ratings (70.6% correct), numbers (62.0%) and bars (54.2%) when viewing performance scores of 20 providers. Furthermore, a reduced number of healthcare providers appeared to support consumers, for example, when provided with 20 providers, 69.5% correctly selected the top three, compared with 80.2% with five providers. Particular presentation formats enhanced consumer understanding of CPI, most importantly the use of overall performance scores, word icons and coloured dots, and a reduced number of providers displayed. Public report efforts should use these formats to maximise impact on consumers. Published by the BMJ Publishing Group Limited.

Adaptation of a paradigm for examining the development of fear beliefs through the verbal information pathway in preschool-age children.

PubMed

Rifkin, Lara S; Schofield, Casey A; Beard, Courtney; Armstrong, Thomas

2016-12-01

Verbal threat information has been shown to induce fear beliefs in school-age children (i.e. 6-12 years; for a review see Muris & Field, 2010). The current study adapted an existing paradigm (Field & Lawson, 2003) to examine the impact of verbal threat information on self-report and behavioral measures of fear in preschool-age children. Thirty children (aged 3-5) were provided with threat, positive, or no information about three novel Australian marsupials. There was a significant increase in fear belief for the animal associated with threat information compared to the animal associated with positive or no information. Verbal threat information did not impact behavioral avoidance in the complete sample; however, findings from an exploratory subgroup analysis excluding three-year-olds indicated that children demonstrated significant behavioral avoidance for the threat condition compared to the positive condition. These findings provide additional support for Rachman's theory of fear acquisition (1977, 1991) and suggest this paradigm may be used to examine the age at which verbal threat information becomes a relevant mode of fear acquisition for young children.

Informal caregivers are essential figures for maintaining frail elderly at home. Providing informal care can affect the informal caregivers' physical and psychological health and labour market participation capabilities. They need support to prevent caregiver burden. A variety of existing support measures can help the caregiver care for the elderly at home, but with some limitations. The objective of this review was to explore the experiences of informal caregivers caring for elderly in the community with the use of supportive policy measures in Belgium and compare these to the experiences in other European countries. An empirical qualitative case study research was conducted in five European countries (Belgium, The Netherlands, Luxembourg, France and Germany). Semi-structured interviews were conducted with informal caregivers and their dependent elderly. Interview data from the different cases were analysed. In particular data from Belgium was compared to data from the cases abroad. Formal services (e.g. home care) were reported to have the largest impact on allowing the caregiver to care for the dependent elderly at home. One of the key issues in Belgium is the lack of timely access to reliable information about formal and informal services in order to proactively support the informal caregiver. Compared to the other countries, informal caregivers in Belgium expressed more difficulties in accessing support measures and navigating through the health system. In the other countries information seemed to be given more timely when home care was provided via care packages. To support the informal caregiver, who is the key person to support the frail elderly, fragmentation of information regarding supportive policy measures is an important issue of concern.

To provide insight into the perceived need for information of patients with haematological malignancies. Providing timely and accurate information to patients diagnosed with a haematological malignancy is a challenge in clinical practice; treatment often has to start promptly, with little time to inform patients. Literature review. A comprehensive literature search was conducted from all available literature to May 2013 in the databases: Cumulative Index to Nursing and Allied Health Literature, PsycINFO and PubMed (Medline). Relevant studies were reviewed regarding the perceived need for information on various topics, sources of information and satisfaction with information provided. The initial search revealed 215 articles, fourteen of which were relevant. Patients need basic information on the disease (diagnosis and diagnostics), treatment (various treatment options, side effects and duration), prognosis (curability and prolonging life) and all other topics (recovery, self-care and psychosocial functioning). Need for detailed information varied between studies. Patients expressed a higher need for medical than for psychosocial information. Patients preferred to receive information from their doctors the most, followed by nurses. Most studies described patients' satisfaction with the information provided. Based on the limited number of data available, medical information is for patients of higher priority compared to psychosocial information. Patients need basic information on diagnosis, treatment, prognosis and all other topics. Need for detailed information varied between studies. Patients were satisfied with the provided information, preferably offered by doctors and nurses. The perceived need for information and satisfaction with the information provided differs strongly between patients. In clinical practice, more attention is needed for information tailored to the patient, taking into account important moderating factors such as age, type of cancer, time since diagnosis, treatment modality and coping style. © 2014 John Wiley & Sons Ltd.

1985-01-01

Digital values in a moving window are compared by an operator having nine comparators connected to line buffers for receiving a succession of central pixels together with eight neighborhood pixels. A single bit of program control determines whether the neighborhood pixels are to be compared with the central pixel or a threshold value. The central pixel is always compared with the threshold. The omparator output plus 2 bits indicating odd-even pixel/line information about the central pixel addresses a lookup table to provide 14 bits of information, including 2 bits which control a selector to pass either the central pixel value, the other 12 bits of table information, or the bit-wise logical OR of all nine pixels through circuit that implements a very wide OR gate.

2010-09-01

Previously, quality of formulations information provided for oral medications used in paediatric clinical trials published in 10 highly cited journals between 2002 and 2004 raised concerns. This short report explores if there was any subsequent improvement on how the formulations used in trials involving children <12 years reported in the same journals. Studies published between 2004 and 2008 were hand-searched and classified as containing adequate, some or no formulation information. Those involving solid dosage forms were further analysed. Only 31% (44/140) of publications provided adequate information, 5% less compared to 2002-2004 (28/76). There was a significant 12% rise (p<0.05) of no formulation information at all (37/140) and in tablets/capsules use (53/140), of which 3/4 gave no administration details, even for those under 6 years old, but a 12% decline in suitable paediatric formulations use (52/140 compared to 37/76). Contrary to expectations, overall quality of formulation information reported markedly deteriorated, jeopardising validity of clinical outcomes. The situation may reflect continued lack of awareness among investigators and other stakeholders of the importance of using suitable age-appropriate formulations.

Analysis of InsureKidsNow.gov dental providers in New York State.

2013-01-01

Study purposes were to: (1) validate information of New York State (NYS) pediatric dental Medicaid/CHIP providers registered on InsureKidsNow.gov (IKN); and (2) compare dental access to available IKN pediatric dental Medicaid provider locations by NYS region and population density of young children in poverty Methods: Information on 4,634 dental provider locations was obtained by collapsing 21,921 listings; 160 locations were randomly telephoned to verify consistency and provision of pediatric restorative treatment. Dental provider locations to poor child population ratios were compared. Over 90 percent of locations were in less than a third of NYS counties. New York City/Long Island locations had 5.68 higher odds of accepting new pediatric patients compared to locations in the rest of NYS. Of phone numbers called, 22 percent were invalid. Nearly 40 percent of valid calls were inconsistent with IKN. Over 90 percent of counties had at least one IKN dentist. The median child-in-poverty to provider ratio was 85:1.

Obtaining informed consent is an essential step in the surgical pathway. Providing adequate patient education to enable informed decision making is a continued challenge of contemporary surgical practice. This study investigates whether the use of a patient information website, to augment patient education and informed consent for elective orthopaedic procedures is an effective measure. A randomised controlled trial was conducted comparing the quality of informed consent provided by a standard discussion with the treating surgeon compared to augmentation of this discussion with an online education resource (www.orthoanswer.org). Participants were recruited from orthopaedic outpatient clinics. Patients undergoing five common orthopaedic procedures were eligible to participate in the trial. The primary outcome measure was knowledge about their operation. Satisfaction with their informed consent and anxiety relating to their operation were the secondary outcome measures. There was a statistically significant increase in patient knowledge for the intervention arm as compared to the control arm (p < 0.01). Patients in the intervention arm, had an average score of 69.25% (SD 14.91) correct answers as compared to 47.38% (SD 17.77) in the control arm. Satisfaction was also improved in the intervention arm (p = 0.043). There was no statistically significant difference between the control and intervention arm relating to their anxiety scores (p = 0.195). The use of a patient education website as an augment to informed consent improves patient knowledge about their planned operation as well as satisfaction with the consent process whilst not increasing their anxiety levels. We recommend that all patients be directed to web based education tools to augment their consent. Australian New Zealand Clinical Trials Registry (ANZCTR) ACTRN12614001058662 .

Personality traits relate to risk for psychopathology and can inform predictions about treatment outcome. In an effort to obtain a comprehensive index of personality, informant-reports of personality are sometimes obtained in addition to self-reports of personality. However, there is limited research comparing the validity of self- and informant-reports of personality, particularly among those with internalizing psychopathology. This is important given that informants may provide an additional (and perhaps different) perspective on individuals’ personality. The present study therefore compared how both reports of positive affectivity (PA) and negative affectivity (NA) relate to psychophysiological and subjective measures of emotional responding to positive and negative stimuli. Given that our sample (n = 117) included individuals with no history of psychopathology, as well as individuals with major depressive disorder (MDD) and/or panic disorder (PD), we were also able to explore whether these internalizing diagnoses moderated the association between personality reports and measures of emotional responding. Informant-reported PA predicted physiological responses to positive stimuli (but not negative). Informant reported NA predicted physiological responses to negative stimuli (but not positive). Self-reported personality did not predict physiological responding, but did predict subjectively measured emotional responding (NA for negative responding; PA for positive responding). Diagnoses of internalizing psychopathology (PD or MDD) did not moderate these associations. Results suggest self- and informant-reports of personality may each provide valid indices of an individual’s emotional response tendencies, but predict different aspects of those tendencies.

Objective To compare the use and effect of a computer based information system for cancer patients that is personalised using each patient's medical record with a system providing only general information and with information provided in booklets. Design Randomised trial with three groups. Data collected at start of radiotherapy, one week later (when information provided), three weeks later, and three months later. Participants 525 patients started radical radiotherapy; 438 completed follow up. Interventions Two groups were offered information via computer (personalised or general information, or both) with open access to computer thereafter; the third group was offered a selection of information booklets. Outcomes Patients' views and preferences, use of computer and information, and psychological status; doctors' perceptions; cost of interventions. Results More patients offered the personalised information said that they had learnt something new, thought the information was relevant, used the computer again, and showed their computer printouts to others. There were no major differences in doctors' perceptions of patients. More of the general computer group were anxious at three months. With an electronic patient record system, in the long run the personalised information system would cost no more than the general system. Full access to booklets cost twice as much as the general system. Conclusions Patients preferred computer systems that provided information from their medical records to systems that just provided general information. This has implications for the design and implementation of electronic patient record systems and reliance on general sources of patient information. PMID:10550090

Sexual health information seeking on the Internet: comparisons between White and African American college students.

College students are often interested in information about sexual health topics. A study of 149 college students and their use of the Internet for sexual health information was conducted. The study findings indicated that African American college students, as compared to White college students, and women, as compared to men, had greater odds for searching on the Internet for birth control information. Among male college students, a higher internal locus of control was associated with lower odds for looking at birth control information on the Internet. Nurses and healthcare providers working in college settings can use these findings to develop strategies for identifying those who are more likely to reference the Internet to obtain birth control and sexual health information.

United States benefits of improved worldwide wheat crop information from a LANDSAT system overview

NASA Technical Reports Server (NTRS)

1976-01-01

The value of improvements in worldwide information on wheat crops provided by LANDSAT was measured in the context of world wheat markets. These benefits were based on exiting LANDSAT technical goals and assumed that information would be made available to the United States and other countries at the same time. The benefits to the United States of such public LANDSAT information on wheat crops were found to be 174 million dollars a year on the average. The benefits from improved wheat crop information compare favorably with the annual system's cost of about $62 million. A detailed empirical sample demonstration of the effect of improved information was developed. The history of wheat commodity prices for 1971-72 was reconstructed and the price changes from improved vs. historical information were compared.

What do electronic health record vendors reveal about their products: an analysis of vendor websites.

Yeung, Natalie K; Jadad, Alejandro R; Shachak, Aviv

2013-02-19

Purchasing electronic health records (EHRs) typically follows a process in which potential adopters actively seek information, compare alternatives, and form attitudes towards the product. A potential source of information on EHRs that can be used in the process is vendor websites. It is unclear how much product information is presented on EHR vendor websites or the extent of its value during EHR purchasing decisions. To explore what features of EHR systems are presented by vendors in Ontario, Canada, on their websites, and the persuasive means they use to market such systems; to compare the online information available about primary care EHR systems with that about hospital EHR systems, and with data compiled by OntarioMD, a regional certifying agency. A list of EHR systems available in Ontario was created. The contents of vendor websites were analyzed. A template for data collection and organization was developed and used to collect and organize information on the vendor, website content, and EHR features. First, we mapped information on system features to categories based on a framework from the Institute of Medicine (IOM). Second, we used a grounded theory-like approach to explore information for building consumer confidence in the vendor and product, and the various persuasive strategies employed on vendor websites. All data were first coded by one researcher. A peer reviewer independently analyzed a randomly chosen subset of the websites (10 of 21; 48%) and provided feedback towards a unified coding scheme. All data were then re-coded and categorized into themes. Finally, we compared information from vendor websites and data gathered by OntarioMD. Vendors provided little specific product information on their websites. Only two of five acute care EHR websites (40%) and nine of 16 websites for primary care systems (56%) featured seven or all eight of the IOM components. Several vendor websites included system interface demonstrations: screenshots (six websites), public videos or slideshows (four websites), or for registered viewers only (three websites). Persuasive means used by vendors included testimonials on 14/21 (67%) websites, and directional language. Except for one free system, trial EHR versions were not available. OntarioMD provided more comprehensive information about primary care systems than the vendors' websites. Of 14 points of comparison, only the inclusion of templates and bilingual interfaces were fully represented in both data sources. For all other categories, the vendor websites were less complete than the OntarioMD site. EHR vendor websites employ various persuasive means, but lack product-specific information and do not provide options for trying systems on a limited basis. This may impede the ability of potential adopters to form perceptions and compare various offerings. Both vendors and clients could benefit from greater transparency and more specific product information on the Web. N/A.

The majority of primary care physicians support integration of children's oral health promotion and disease prevention into their practices but can experience challenges integrating oral health services into their workflow. Most electronic health records (EHRs) in primary care settings do not include oral health information for pediatric patients. Therefore, it is important to understand providers' preferences for oral health information within the EHR. The objectives of this study are to assess (1) the relative importance of various elements of pediatric oral health information for primary care providers to have in the EHR and (2) the extent to which practice and provider characteristics are associated with these information preferences. We surveyed a sample of primary care physicians who conducted Medicaid well-child visits in North Carolina from August - December 2013. Using descriptive statistics, we analyzed primary care physicians' oral health information preferences relative to their information preferences for traditional preventive aspects of well-child visits. Furthermore, we analyzed associations between oral health information preferences and provider- and practice-level characteristics using an ordinary least squares regression model. Fewer primary care providers reported that pediatric oral health information is "very important," as compared to more traditional elements of primary care information, such as tracking immunizations. However, the majority of respondents reported some elements of oral health information as being very important. Also, we found positive associations between the percentage of well child visits in which oral health screenings and oral health referrals are performed and the reported importance of having pediatric oral health information in the EHR. Incorporating oral health information into the EHR may be desirable for providers, particularly those who perform oral health screenings and dental referrals.

One quarter of randomized clinical trials (RCTs) are prematurely discontinued and frequently remain unpublished. Trial registries can document whether a trial is ongoing, suspended, discontinued, or completed and therefore represent an important source for trial status information. The accuracy of this information is unclear. To examine the accuracy of completion status and reasons for discontinuation documented in trial registries as compared to corresponding publications of discontinued RCTs and to investigate potential predictors for accurate trial status information in registries. We conducted a cross-sectional study comparing information provided in publications (reference standard) to corresponding registry entries. First, we reviewed publications of RCTs providing information on both discontinuation and registration. We identified eligible publications through systematic searches of MEDLINE and EMBASE (2010-2014) and an international cohort of 1,017 RCTs initiated between 2000 and 2003. Second, pairs of investigators independently and in duplicate extracted data from publications and corresponding registry records. Third, for each discontinued RCT, we compared publication information to registry information. We used multivariable regression to examine whether accurate labeling of trials as discontinued (vs. other status) in the registry was associated with recent initiation of RCT, industry sponsorship, multicenter design, or larger sample size. We identified 173 publications of RCTs that were discontinued due to slow recruitment (55%), harm (16%), futility (11%), benefit (5%), other reasons (3%), or multiple reasons (9%). Trials were registered with clinicaltrials.gov (77%), isrctn.com (14%), or other registries (8%). Of the 173 corresponding registry records, 77 (45%) trials were labeled as discontinued and 57 (33%) provided a reason for discontinuation (of which 53, 93%, provided the same reason as in the publication). Labeling of discontinued trials as discontinued (vs. other label) in corresponding trial registry records improved over time (adjusted odds ratio 1.16 per year, confidence interval 1.04-1.30) and was possibly associated with industry sponsorship (2.01, 0.99-4.07) but unlikely with multicenter status (0.81, 0.32-2.04) or sample size (1.07, 0.89-1.29). Less than half of published discontinued RCTs were accurately labelled as discontinued in corresponding registry records. One-third of registry records provided a reason for discontinuation. Current trial status information in registries should be viewed with caution. Copyright © 2016 Elsevier Inc. All rights reserved.

Ooi, Choon Ean; Rofe, Olivia; Vienet, Michelle; Elliott, Rohan A

2017-04-01

Background Discontinuity of care between hospital and primary care is often due to poor information transfer. Medication information in medical discharge summaries (DS) is often incomplete or incorrect. The effectiveness and feasibility of hospital pharmacists communicating medication information, including changes made in the hospital, is not clearly defined. Objective To explore the impact of a pharmacist-prepared Discharge Medication Management Summary (DMMS) on the accuracy of information about medication changes provided to patients' general practitioners (GPs). Setting Two medical wards at a major metropolitan hospital in Australia. Method An intervention was developed in which ward pharmacists communicated medication change information to GPs using the DMMS. Retrospective audits were conducted at baseline and after implementation of the DMMS to compare the accuracy of information provided by doctors and pharmacists. GPs' satisfaction with the DMMS was assessed through a faxed survey. Main outcome measure Accuracy of medication change information communicated to GPs; GP satisfaction and feasibility of a pharmacist-prepared DMMS. Results At baseline, 263/573 (45.9%) medication changes were documented by doctors in the DS. In the post-intervention audit, more medication changes were documented in the pharmacist-prepared DMMS compared to the doctor-prepared DS (72.8% vs. 31.5%; p < 0.001). Most GPs (73.3%) were satisfied with the information provided and wanted to receive the DMMS in the future. Completing the DMMS took pharmacists an average of 11.7 minutes. Conclusion The accuracy of medication information transferred upon discharge can be improved by expanding the role of hospital pharmacists to include documenting medication changes.

Disclosure and rationality: comparative risk information and decision-making about prevention.

PubMed

Schwartz, Peter H

2009-01-01

With the growing focus on prevention in medicine, studies of how to describe risk have become increasing important. Recently, some researchers have argued against giving patients "comparative risk information," such as data about whether their baseline risk of developing a particular disease is above or below average. The concern is that giving patients this information will interfere with their consideration of more relevant data, such as the specific chance of getting the disease (the "personal risk"), the risk reduction the treatment provides, and any possible side effects. I explore this view and the theories of rationality that ground it, and I argue instead that comparative risk information can play a positive role in decision-making. The criticism of disclosing this sort of information to patients, I conclude, rests on a mistakenly narrow account of the goals of prevention and the nature of rational choice in medicine.

Package inserts (PIs) as a reliable reference for patients and health care providers should provide accurate, complete and up-to-date information. The purpose of the current study is to assess and compare the PIs of antihypertensive agents locally produced in Palestine and their imported counterparts. Thirty-five PIs were assessed for the presence of 31 information statements using a scoring method. Word counting of 20 headings and subheadings was used to evaluate and compare local and imported PIs for information quantity. None of the analysed PIs fulfilled the criteria. All of them included the brand name, active ingredients, indications, directions for use, adverse drug reactions, drug-drug interactions, pregnancy and lactation considerations, and storage. Whereas none of them, either local or imported PIs, included the shelf life and instructions to convert tablets or capsules into liquid forms. Additionally, only one (5%) imported and no (0%) local PIs mentioned the duration of therapy. Moreover, 93.4% of local PIs were deficient in areas regarding the inactive ingredients and date of last revision, and 86.7% did not mention the drug dose and possibility of tablet splitting. Furthermore, the maximum dose was not indicated in 90% of imported and 86.7% of local PIs. In general, imported PIs contained more detailed information than their local counterparts, where the range of differences in medians between the local and imported PIs was from 1.5-fold for pregnancy considerations to >42.00-fold for the effect on the ability to drive and use machines. The findings of this study revealed the superiority of imported over local PIs in both quality and quantity of information provided. This emphasises the need for appropriate measures to be taken by the Ministry of Health and local manufacturers to ensure efficiency of local PIs in providing accurate, complete and up-to-date information.

Analgesia Is Enhanced by Providing Information regarding Good Outcomes Associated with an Odor: Placebo Effects in Aromatherapy?

No previous report has described whether information regarding an odor used in aromatherapy has placebo effects. We investigated whether placebo analgesia was engendered by verbal information regarding the analgesic effects of an odor. Twelve of 24 subjects were provided with the information that a lavender odor would reduce pain (informed), whereas the other 12 subjects were not (not-informed). Concurrent with respiration recording, the subjects were administered a lavender-odor or no-odor treatment during application of painful stimulation to the forefinger. The subjects reported their experience of pain and its unpleasantness on a visual analogue scale after the painful stimulation. The lavender-odor treatment significantly alleviated pain and unpleasantness compared with the no-odor treatment in the informed (P < 0.01) and not-informed groups (P < 0.05). The no-odor treatment in the informed group significantly alleviated pain and unpleasantness compared with both the no-odor and lavender-odor treatments in the not-informed group (P < 0.05). Rapid and shallow breathing induced by the painful stimulation became slow and deep during the lavender-odor and no-odor treatments in both groups. Information regarding a lavender odor, the lavender odor itself, and slower breathing contributed to reduced perceptions of pain and unpleasantness during painful stimulation, suggesting that placebo effects significantly contribute to analgesia in aromatherapy.

Prostate-specific antigen (PSA) screening is controversial, and little is known regarding a physician's effect on a patient's decision to undergo screening. This study's objective was to evaluate the effect of a patient's understanding of the risks and benefits of screening compared to the final recommendation of the provider on the patient's decision to undergo PSA screening. Using the 2012 Behavioral Risk Factor Surveillance System, men older than 55 years who did not have a history of prostate cancer/prostate "problem" and who reported a PSA test within the preceding year were considered to have undergone screening. The percentages of men informed and not informed of the risks and benefits of screening and the percentage men receiving recommendations for PSA screening from their provider were reported. Multivariable complex-sample logistic regression calculated the odds of undergoing screening. In all, 75% of men were informed of screening benefits; however, 32% were informed of screening risks. After being informed of both, 56% of men opted for PSA screening if the provider recommended it, compared with only 21% when not recommended. Men receiving a recommendation to undergo PSA testing had higher odds of undergoing screening (odds ratio [OR] = 4.98, 95% CI: 4.53-5.48) compared with those who were only informed about screening benefits (OR = 2.40, 95% CI: 2.18-2.65) or risks (OR = 0.92, 95% CI: 0.86-0.98). Significant limitations include recall and nonresponse bias. Patients' decision to undergo or forgo PSA screening is heavily influenced by the recommendation of their physician; it is imperative that physicians are cognizant of their biases and facilitate a shared decision-making process.

You might as well smoke; the misleading and harmful public message about smokeless tobacco.

PubMed

Phillips, Carl V; Wang, Constance; Guenzel, Brian

2005-04-05

Compared to smoking cigarettes, use of Western smokeless tobacco (ST) products is associated with a very small risk of life-threatening disease (with estimates in the range of a few percent of the risk from smoking, or even less). This means that smokers can realize substantial health benefits by switching to ST, an obvious substitute. But consumers and policy makers have little chance of learning that ST is much less dangerous than smoking because popular information provided by experts and advocates overstates the health risks from ST relative to cigarettes. To examine the extent of this overstatement in one medium, we conducted a systematic review of websites containing information about ST and health risks. We examined the content of 316 relevant websites identified by a Google search. We found that when any substantive information about the risk from ST is given, the risk is almost universally conflated with the risk from cigarettes. Accurate comparative risk information was quite rare, provided by only a handful of websites, all appearing low in our search results (i.e., of low popularity and thus unlikely to be found by someone searching for information). About 1/3 of the websites, including various authoritative entities, explicitly claimed that ST is as bad as or worse than cigarettes. Most of the other sites made statements that imply the risks are comparable. Through these websites, and presumably other information provided by the same government, advocacy, and educational organizations, ST users are told, in effect, that they might as well switch to smoking if they like it a bit more. Smokers and policy makers are told there is no potential for harm reduction. These messages are clearly false and likely harmful, representing violations of ethical standards.

The internet is an emerging source of information for prostate cancer (PCa) patients. Since little is known about the quality of information on PCa provided online, we investigated its accordance to the latest European Association of Urology (EAU) guidelines. A total of 89 German web pages were included for analysis. A quality model classifying the provider of information and its expertise was introduced. Correctness of provided information was systematically compared to the EAU guidelines. Information was provided by medical experts (41%), media (11%), and pharmaceutical companies (6%). Certificates were found in 23% with a significantly higher rate if provided by medical experts (p = 0.003). The minority of web pages showed information in accordance with the EAU guidelines regarding screening (63%), diagnosis (32%), classification (39%), therapy (36%), complications (8%), and follow-up (27%). Web pages by medical experts as well as websites with any kind of certification showed a significantly higher guideline conformity regarding diagnosis (p = 0.027, p = 0.002), therapy (p = 0.010, p = 0.011), follow-up (p = 0.005, p < 0.001), and availability of references (p = 0.017, p = 0.003). The present study reveals that online health information on PCa lacks concordance to current guidelines. Certified websites or websites provided by medical experts showed a significantly higher quality and accordance with guidelines. © 2018 S. Karger AG, Basel.

Background The Internet has increasingly become a popular source of health information by connecting individuals with health content, experts, and support. More and more, individuals turn to social media and Internet sites to share health information and experiences. Although online health information seeking occurs worldwide, limited empirical studies exist examining cross-cultural differences in perceptions about user-generated, experience-based information compared to expertise-based information sources. Objective To investigate if cultural variations exist in patterns of online health information seeking, specifically in perceptions of online health information sources. It was hypothesized that Koreans and Hongkongers, compared to Americans, would be more likely to trust and use experience-based knowledge shared in social Internet sites, such as social media and online support groups. Conversely, Americans, compared to Koreans and Hongkongers, would value expertise-based knowledge prepared and approved by doctors or professional health providers more. Methods Survey questionnaires were developed in English first and then translated into Korean and Chinese. The back-translation method ensured the standardization of questions. Surveys were administered using a standardized recruitment strategy and data collection methods. Results A total of 826 participants living in metropolitan areas from the United States (n=301), Korea (n=179), and Hong Kong (n=337) participated in the study. We found significant cultural differences in information processing preferences for online health information. A planned contrast test revealed that Koreans and Hongkongers showed more trust in experience-based health information sources (blogs: t 451.50=11.21, P<.001; online support group: t 455.71=9.30, P<.001; social networking sites [SNS]: t 466.75=11.36, P<.001) and also reported using blogs (t 515.31=6.67, P<.001) and SNS (t 529.22=4.51, P<.001) more frequently than Americans. Americans showed a stronger preference for using expertise-based information sources (eg, WebMD and CDC) compared to Koreans and Hongkongers (t 360.02=3.01, P=.003). Trust in expertise-based information sources was universal, demonstrating no cultural differences (Brown-Forsythe F 2,654=1.82, P=.16). Culture also contributed significantly to differences in searching information on behalf of family members (t 480.38=5.99, P<.001) as well as to the goals of information searching. Conclusions This research found significant cultural differences in information processing preferences for online health information. Further discussion is included regarding effective communication strategies in providing quality health information. PMID:26976273

Trust in expertise-based information sources was universal, demonstrating no cultural differences (Brown-Forsythe F2,654=1.82, P=.16). Culture also contributed significantly to differences in searching information on behalf of family members (t480.38=5.99, P<.001) as well as to the goals of information searching. This research found significant cultural differences in information processing preferences for online health information. Further discussion is included regarding effective communication strategies in providing quality health information.

Privacy policy analysis for health information networks and regional health information organizations.

Noblin, Alice M

2007-01-01

Regional Health Information Organizations (RHIOs) are forming in response to President George W. Bush's 2004 mandate that medical information be made available electronically to facilitate continuity of care. Privacy concerns are a deterrent to widespread acceptance of RHIOs. The Health Information Portability and Accountability Act of 1996 provides some guidelines for privacy protection. However, most states have stricter guidelines, causing difficulty when RHIOs form across these jurisdictions. This article compares several RHIOs including their privacy policies where available. In addition, studies were reviewed considering privacy concerns of people in the United States and elsewhere. Surveys reveal that Americans are concerned about the privacy of their personal health information and ultimately feel it is the role of the government to provide protection. The purpose of this article is to look at the privacy issues and recommend a policy that may help to resolve some of the concerns of both providers and patients. Policy research and action are needed to move the National Health Information Network toward reality. Efforts to provide consistency in privacy laws are a necessary early step to facilitate the construction and maintenance of RHIOs and the National Health Information Network.

Searching the Internet for information on prostate cancer screening: an assessment of quality.

Ilic, Dragan; Risbridger, Gail; Green, Sally

2004-07-01

To identify how on-line information relating to prostate cancer screening (PCS) is best sourced, whether through general, medical, or meta-search engines, and to assess the quality of that information. Websites providing information about PCS were searched across 15 search engines representing three distinct types: general, medical, and meta-search engines. The quality of on-line information was assessed using the DISCERN quality assessment tool. Quality performance characteristics were analyzed by performing Mann-Whitney U tests. Search engine efficiency was measured by each search query as a percentage of the relevant websites included for analysis from the total returned and analyzed by performing Kruskal-Wallis analysis of variance. Of 6690 websites reviewed, 84 unique websites were identified as providing information relevant to PCS. General and meta-search engines were significantly more efficient at retrieving relevant information on PCS compared with medical search engines. The quality of information was variable, with most of a poor standard. Websites that provided referral links to other resources and a citation of evidence provided a significantly better quality of information. In contrast, websites offering a direct service were more likely to provide a significantly poorer quality of information. The current lack of a clear consensus on guidelines and recommendation in published data is also reflected by the variable quality of information found on-line. Specialized medical search engines were no more likely to retrieve relevant, high-quality information than general or meta-search engines.

College health professionals must find new ways of educating students on finding and evaluating consumer health information, specifically in the online environment. Librarians are trained as information professionals; however, librarians at general academic libraries are not taking a lead role in providing consumer health information. The authors' purpose in this research was to determine the health information resource needs of college and university students and provide a model for collaboration between college health professionals and academic librarians. The authors compared data from a national survey on college health (N = 54,111) with their own results from a survey of general academic librarians (N = 17) to create recommendations for synching students' reported health information needs with librarians' resources. Although the Internet was students' second most-often consulted health information source, they ranked the believability of online health information above only television. In the librarian survey, although 12 respondents indicated that health information provision is a library's responsibility, the majority (n = 11) believed their library's consumer health outreach to be passive. The authors offer recommendations for partnerships between college healthcare professionals and academic librarians to better provide this information to students.

To examine the effectiveness of newly developed materials for providing health-related information to the worksite population, we compared the amount of attention that employees paid to the materials. Study subjects were 2,361 employees in six companies participating in an intervention program between 2002 and 2003. Three kinds of media were used as tools for providing health information: [1] Point Of Purchase advertising menus (POP menus) were placed on all tables in company restaurants, [2] posters were put on walls and [3] leaflets were distributed at health-related events. One year or more after the introduction of these media, we compared the amount of attention paid to each type of medium. Amongst the three types of media, the POP menu drew the most attention, although results were not consistent in all gender and company groups. Every piece of information provided by the POP menus was "always" or "almost always" read by 41% of the men and 51% of the women surveyed. The corresponding rate for posters was 30% in men and 32% in women. For leaflets, only 16% of men and 22% of women read almost all of the leaflets. More attention was paid to the POP menu when the sample was women, older, and ate at the company restaurant at least three times a week. The POP menu may provide health-related information to a broader range of people than posters and leaflets, therefore, it is an effective material for population strategy.

In this study, we evaluate the role of information anxiety and information load on the intention to read information from prescription drug information leaflets (PILs). These PILs were developed based on the principals of information load and consumer information processing. This was an experimental prospective repeated measures study conducted in the United States where 360 (62% response rate) university students (>18 years old) participated. Participants were presented with a scenario followed by exposure to the three drug product information sources used to operationalize information load. The three sources were: (i) current practice; (ii) pre-existing one-page text only; and (iii) interventional one-page prototype PILs designed for the study. Information anxiety was measured as anxiety experienced by the individual when encountering information. The outcome variable of intention to read PILs was defined as the likelihood that the patient will read the information provided in the leaflets. A survey questionnaire was used to capture the data and the objectives were analyzed by performing a repeated measures MANOVA using SAS version 9.3. When compared to current practice and one-page text only leaflets, one-page PILs had significantly lower scores on information anxiety ( p < 0.001) and information load ( p < 0.001). The intention to read was highest and significantly different ( p < 0.001) for PILs as compared to current practice or text only leaflets. Information anxiety and information load significantly impacted intention to read ( p < 0.001). Newly developed PILs increased patient's intention to read and can help in improving the counseling services provided by pharmacists.

The Goldstone Solar System Radar (GSSR) has collected a self-consistent set of delay-Doppler near-nadir radar echo data from Mars since 1988. Prior to the Mars Global Surveyor (MGS) Mars Orbiter Laser Altimeter (MOLA) global topography for Mars, these radar data provided local elevation information, along with radar scattering information with global coverage. Two kinds of GSSR Mars delay-Doppler data exist: low 5 km x 150 km resolution and, more recently, high (5 to 10 km) spatial resolution. Radar data, and non-imaging delay-Doppler data in particular, requires significant data processing to extract elevation, reflectivity and roughness of the reflecting surface. Interpretation of these parameters, while limited by the complexities of electromagnetic scattering, provide information directly relevant to geophysical and geomorphic analyses of Mars. In this presentation we want to demonstrate how to compare GSSR delay-Doppler data to other Mars datasets, including some idiosyncracies of the radar data. Additional information is included in the original extended abstract.

Online knowledge resources such as Medline can address most clinicians’ patient care information needs. Yet, significant barriers, notably lack of time, limit the use of these sources at the point of care. The most common information needs raised by clinicians are treatment-related. Comparative effectiveness studies allow clinicians to consider multiple treatment alternatives for a particular problem. Still, solutions are needed to enable efficient and effective consumption of comparative effectiveness research at the point of care. Objective Design and assess an algorithm for automatically identifying comparative effectiveness studies and extracting the interventions investigated in these studies. Methods The algorithm combines semantic natural language processing, Medline citation metadata, and machine learning techniques. We assessed the algorithm in a case study of treatment alternatives for depression. Results Both precision and recall for identifying comparative studies was 0.83. A total of 86% of the interventions extracted perfectly or partially matched the gold standard. Conclusion Overall, the algorithm achieved reasonable performance. The method provides building blocks for the automatic summarization of comparative effectiveness research to inform point of care decision-making. PMID:23920677

Comparing the validity of informant and self-reports of personality using laboratory indices of emotional responding as criterion variables.

Personality traits relate to risk for psychopathology and can inform predictions about treatment outcome. In an effort to obtain a comprehensive index of personality, informant reports of personality are sometimes obtained in addition to self-reports of personality. However, there is limited research comparing the validity of self- and informant reports of personality, particularly among those with internalizing psychopathology. This is important given that informants may provide an additional (and perhaps different) perspective on individuals' personality. The present study therefore compared how both reports of positive affectivity (PA) and negative affectivity (NA) relate to psychophysiological and subjective measures of emotional responding to positive and negative stimuli. Given that our sample (n = 117) included individuals with no history of psychopathology, as well as individuals with major depressive disorder (MDD) and/or panic disorder (PD), we were also able to explore whether these internalizing diagnoses moderated the association between personality reports and measures of emotional responding. Informant-reported PA predicted physiological responses to positive stimuli (but not negative). Informant-reported NA predicted physiological responses to negative stimuli (but not positive). Self-reported personality did not predict physiological responding, but did predict subjectively measured emotional responding (NA for negative responding, PA for positive responding). Diagnoses of internalizing psychopathology (PD or MDD) did not moderate these associations. Results suggest self- and informant reports of personality may each provide valid indices of an individual's emotional response tendencies, but predict different aspects of those tendencies. © 2016 Society for Psychophysiological Research.

Although growing research supports cancer survivor information-seeking, little is known about breast cancer prevention information-seeking among women. The purpose of the study was to examine differences in breast cancer risk factor knowledge, information sources, and desired mobile messages among Hispanic and non-Hispanic rural women. Women were recruited to complete a survey at an imaging center during a mammography screening visit. A total of 156 women (mean age = 61, SD = 12.07) completed the survey. Breast cancer risk factor knowledge was significantly higher for non-Hispanic women compared to Hispanic women (p = .035). Television, magazines, and Internet were the most frequent information sources. Providers were the most frequent interpersonal information source. Nearly 87 % used cell phones and 47 % used texting. Hispanic women were more likely to desire breast cancer prevention cell voice messages (p < .001) and text messages (p = .001) compared to non-Hispanic women. No significant differences were found for text appointment reminders by ethnicity. Health educators and clinicians must promote mobile messages for Hispanics and non-Hispanics for mammography adherence, breast cancer prevention education, and best practices to manage screening appointments.

Many workers have questions about occupational safety and health (OSH). It is unknown whether workers are able to find correct, evidence-based answers to OSH questions when they use common information sources, such as websites, or whether they would benefit from using an easily accessible, free-of-charge online network of OSH experts providing advice. To assess the rate of correct, evidence-based answers to OSH questions in a group of workers who used an online network of OSH experts (intervention group) compared with a group of workers who used common information sources (control group). In a quasi-experimental study, workers in the intervention and control groups were randomly offered 2 questions from a pool of 16 standardized OSH questions. Both questions were sent by mail to all participants, who had 3 weeks to answer them. The intervention group was instructed to use only the online network ArboAntwoord, a network of about 80 OSH experts, to solve the questions. The control group was instructed that they could use all information sources available to them. To assess answer correctness as the main study outcome, 16 standardized correct model answers were constructed with the help of reviewers who performed literature searches. Subsequently, the answers provided by all participants in the intervention (n = 94 answers) and control groups (n = 124 answers) were blinded and compared with the correct model answers on the degree of correctness. Of the 94 answers given by participants in the intervention group, 58 were correct (62%), compared with 24 of the 124 answers (19%) in the control group, who mainly used informational websites found via Google. The difference between the 2 groups was significant (rate difference = 43%, 95% confidence interval [CI] 30%-54%). Additional analysis showed that the rate of correct main conclusions of the answers was 85 of 94 answers (90%) in the intervention group and 75 of 124 answers (61%) in the control group (rate difference = 29%, 95% CI 19%-40%). Remarkably, we could not identify differences between workers who provided correct answers and workers who did not on how they experienced the credibility, completeness, and applicability of the information found (P > .05). Workers are often unable to find correct answers to OSH questions when using common information sources, generally informational websites. Because workers frequently misjudge the quality of the information they find, other strategies are required to assist workers in finding correct answers. Expert advice provided through an online expert network can be effective for this purpose. As many people experience difficulties in finding correct answers to their health questions, expert networks may be an attractive new source of information for health fields in general.

This article describes sources of health information, types of tobacco information sought, and trust in sources of tobacco information among U.S. racial/ethnic groups (Whites, Blacks, Hispanics, Asian and Pacific Islanders, and Other). Cross-sectional data (N = 3,788) from a nationally representative survey, HINTS-FDA 2015, were analyzed to examine unadjusted and adjusted associations between race/ethnicity and (a) first source of health information, (b) tobacco information seeking, and (c) trust in sources of tobacco information. Adjusted associations controlled for current tobacco product use and sociodemographic variables. Findings indicated that the Internet was the most common first source of health information while health care providers were the second most common source for all racial/ethnic groups. Tobacco-related health information seeking was more prevalent than other tobacco product information seeking. Unadjusted analyses indicated that a higher proportion of Whites sought other tobacco product information compared to Asians and Pacific Islanders. Trust was rated highest for doctors while trust for health organizations was rated second highest. Asians and Pacific Islanders had higher trust in the government compared to all other groups. Blacks had higher trust in religious organizations compared to all other groups besides Hispanics. Blacks had higher trust for tobacco companies compared to Whites and Other. Many of these differences were attenuated in adjusted analyses. This research has implications for tobacco control practice and policymaking by identifying potential dissemination strategies.

An efficient chaotic maps-based authentication and key agreement scheme using smartcards for telecare medicine information systems.

Lee, Tian-Fu

2013-12-01

A smartcard-based authentication and key agreement scheme for telecare medicine information systems enables patients, doctors, nurses and health visitors to use smartcards for secure login to medical information systems. Authorized users can then efficiently access remote services provided by the medicine information systems through public networks. Guo and Chang recently improved the efficiency of a smartcard authentication and key agreement scheme by using chaotic maps. Later, Hao et al. reported that the scheme developed by Guo and Chang had two weaknesses: inability to provide anonymity and inefficient double secrets. Therefore, Hao et al. proposed an authentication scheme for telecare medicine information systems that solved these weaknesses and improved performance. However, a limitation in both schemes is their violation of the contributory property of key agreements. This investigation discusses these weaknesses and proposes a new smartcard-based authentication and key agreement scheme that uses chaotic maps for telecare medicine information systems. Compared to conventional schemes, the proposed scheme provides fewer weaknesses, better security, and more efficiency.

Providing health program information to vulnerable communities, such as Latino farmworkers, is difficult. This analysis describes the manner in which farmworkers receive information about the Affordable Care Act, comparing farmworkers with other Latinos. Interviews were conducted with 100 Latino farmworkers and 100 urban Latino North Carolina residents in 2015. Most farmworkers had received health information from a community organization. Trusted sources for health information were health care providers and community organizations. Sources that would influence decisions to enroll were Latino nurses and doctors, religious leaders, and family members. Traditional media, including oral presentation and printed material at the doctor's office, were preferred by the majority of farmworkers and non-farmworkers. Farmworkers used traditional electronic media: radio, television, and telephone. More non-farmworkers used current electronic media: e-mail and Internet. Latino farmworkers and non-farmworkers prefer traditional media in the context of a health care setting. They are willing to try contemporary electronic media for this information.

High-resolution axial and coronal computed tomographic (CT) scans were compared with coronal and sagittal complex motion tomograms in patients with suspected middle ear cholesteatomas. Information on CT scans equaled or exceeded that on conventional complex motion tomograms in 16 of 17 patients, and in 11 it provided additional information. Soft-tissue resolution was superior with CT. In 14 patients who underwent surgery, CT provided information that was valuable to the surgeon. On the basis of this study, high-resolution CT is recommended as the preferred method for evaluating most patients with cholesteatomas of the temporal bone.

Driving Toward Guiding Principles

As health care moves from paper to electronic data collection, providing easier access and dissemination of health information, the development of guiding privacy, confidentiality, and security principles is necessary to help balance the protection of patients' privacy interests against appropriate information access. A comparative review and analysis was done, based on a compilation of privacy, confidentiality, and security principles from many sources. Principles derived from ten identified sources were compared with each of the compiled principles to assess support level, uniformity, and inconsistencies. Of 28 compiled principles, 23 were supported by at least 50 percent of the sources. Technology could address at least 12 of the principles. Notable consistencies among the principles could provide a basis for consensus for further legislative and organizational work. It is imperative that all participants in our health care system work actively toward a viable resolution of this information privacy debate. PMID:10094065

What Do Electronic Health Record Vendors Reveal About Their Products: An Analysis of Vendor Websites

PubMed Central

Yeung, Natalie K; Jadad, Alejandro R

2013-01-01

Background Purchasing electronic health records (EHRs) typically follows a process in which potential adopters actively seek information, compare alternatives, and form attitudes towards the product. A potential source of information on EHRs that can be used in the process is vendor websites. It is unclear how much product information is presented on EHR vendor websites or the extent of its value during EHR purchasing decisions. Objective To explore what features of EHR systems are presented by vendors in Ontario, Canada, on their websites, and the persuasive means they use to market such systems; to compare the online information available about primary care EHR systems with that about hospital EHR systems, and with data compiled by OntarioMD, a regional certifying agency. Methods A list of EHR systems available in Ontario was created. The contents of vendor websites were analyzed. A template for data collection and organization was developed and used to collect and organize information on the vendor, website content, and EHR features. First, we mapped information on system features to categories based on a framework from the Institute of Medicine (IOM). Second, we used a grounded theory–like approach to explore information for building consumer confidence in the vendor and product, and the various persuasive strategies employed on vendor websites. All data were first coded by one researcher. A peer reviewer independently analyzed a randomly chosen subset of the websites (10 of 21; 48%) and provided feedback towards a unified coding scheme. All data were then re-coded and categorized into themes. Finally, we compared information from vendor websites and data gathered by OntarioMD. Results Vendors provided little specific product information on their websites. Only two of five acute care EHR websites (40%) and nine of 16 websites for primary care systems (56%) featured seven or all eight of the IOM components. Several vendor websites included system interface demonstrations: screenshots (six websites), public videos or slideshows (four websites), or for registered viewers only (three websites). Persuasive means used by vendors included testimonials on 14/21 (67%) websites, and directional language. Except for one free system, trial EHR versions were not available. OntarioMD provided more comprehensive information about primary care systems than the vendors’ websites. Of 14 points of comparison, only the inclusion of templates and bilingual interfaces were fully represented in both data sources. For all other categories, the vendor websites were less complete than the OntarioMD site. Conclusions EHR vendor websites employ various persuasive means, but lack product-specific information and do not provide options for trying systems on a limited basis. This may impede the ability of potential adopters to form perceptions and compare various offerings. Both vendors and clients could benefit from greater transparency and more specific product information on the Web. Trial Registration N/A PMID:23422722

Sesame (Sesamum indicum L.) is an ancient and important oilseed crop grown widely in tropical and subtropical areas. It belongs to the gigantic order Lamiales, which includes many well-known or economically important species, such as olive (Olea europaea), leonurus (Leonurus japonicus) and lavender (Lavandula spica), many of which have important pharmacological properties. Despite their importance, genetic and genomic analyses on these species have been insufficient due to a lack of reference genome information. The now available S. indicum genome will provide an unprecedented opportunity for studying both S. indicum genetic traits and comparative genomics. To deliver S. indicum genomic information to the worldwide research community, we designed Sinbase, a web-based database with comprehensive sesame genomic, genetic and comparative genomic information. Sinbase includes sequences of assembled sesame pseudomolecular chromosomes, protein-coding genes (27,148), transposable elements (372,167) and non-coding RNAs (1,748). In particular, Sinbase provides unique and valuable information on colinear regions with various plant genomes, including Arabidopsis thaliana, Glycine max, Vitis vinifera and Solanum lycopersicum. Sinbase also provides a useful search function and data mining tools, including a keyword search and local BLAST service. Sinbase will be updated regularly with new features, improvements to genome annotation and new genomic sequences, and is freely accessible at http://ocri-genomics.org/Sinbase/. © The Author 2014.

COMPARISON FRICTION: EXPERIMENTAL EVIDENCE FROM MEDICARE DRUG PLANS*

Kling, Jeffrey R.; Mullainathan, Sendhil; Shafir, Eldar; Vermeulen, Lee; Wrobel, Marian V.

Consumers need information to compare alternatives for markets to function efficiently. Recognizing this, public policies often pair competition with easy access to comparative information. The implicit assumption is that comparison friction—the wedge between the availability of comparative information and consumers’ use of it—is inconsequential because information is readily available and consumers will access this information and make effective choices. We examine the extent of comparison friction in the market for Medicare Part D prescription drug plans in the United States. In a randomized field experiment, an intervention group received a letter with personalized cost information. That information was readily available for free and widely advertised. However, this additional step—providing the information rather than having consumers actively access it—had an impact. Plan switching was 28 percent in the intervention group, versus 17 percent in the comparison group, and the intervention caused an average decline in predicted consumer cost of about $100 per year among letter recipients—roughly 5 percent of the cost in the comparison group. Our results suggest that comparison friction can be large even when the cost of acquiring information is small, and may be relevant for a wide range of public policies that incorporate consumer choice.

Understanding the Digital Gap Among US Adults With Disability: Cross-Sectional Analysis of the Health Information National Trends Survey 2013.

PubMed

Kim, Eun Ji; Yuan, Yiyang; Liebschutz, Jane; Cabral, Howard; Kazis, Lewis

2018-03-16

Disabilities affect more than 1 in 5 US adults, and those with disabilities face multiple barriers in accessing health care. A digital gap, defined as the disparity caused by differences in the ability to use advanced technologies, is assumed to be prevalent among individuals with disabilities. This study examined the associations between disability and use of information technology (IT) in obtaining health information and between trust factors and IT use. We hypothesized that compared to US adults without disabilities, those with disabilities are less likely to refer to the internet for health information, more likely to refer to a health care provider to obtain health information, and less likely to use IT to exchange medical information with a provider. Additionally, we hypothesized that trust factors, such as trust toward health information source and willingness to exchange health information, are associated with IT use. The primary database was the 2013 Health Information National Trends Survey 4 Cycle 3 (N=3185). Disability status, the primary study covariate, was based on 6 questions that encompassed a wide spectrum of conditions, including impairments in mobility, cognition, independent living, vision, hearing, and self-care. Study covariates included sociodemographic factors, respondents' trust toward the internet and provider as information sources, and willingness to exchange medical information via IT with providers. Study outcomes were the use of the internet as the primary health information source, use of health care providers as the primary health information source, and use of IT to exchange medical information with providers. We conducted multivariate logistic regressions to examine the association between disability and study outcomes controlling for study covariates. Multiple imputations with fully conditional specification were used to impute missing values. We found presence of any disability was associated with decreased odds (adjusted odds ratio [AOR] 0.65, 95% CI 0.43-0.98) of obtaining health information from the internet, in particular for those with vision disability (AOR 0.27, 95% CI 0.11-0.65) and those with mobility disability (AOR 0.51, 95% CI 0.30-0.88). Compared to those without disabilities, those with disabilities were significantly more likely to consult a health care provider for health information in both actual (OR 2.21, 95% CI 1.54-3.18) and hypothetical situations (OR 1.80, 95% CI 1.24-2.60). Trust toward health information from the internet (AOR 3.62, 95% CI 2.07-6.33), and willingness to exchange via IT medical information with a provider (AOR 1.88, 95% CI 1.57-2.24) were significant predictors for seeking and exchanging such information, respectively. A potential digital gap may exist among US adults with disabilities in terms of their recent use of the internet for health information. Trust toward health information sources and willingness play an important role in people's engagement in use of the internet for health information. Future studies should focus on addressing trust factors associated with IT use and developing tools to improve access to care for those with disabilities. ©Eun Ji Kim, Yiyang Yuan, Jane Liebschutz, Howard Cabral, Lewis Kazis.

Health care costs incurred prior to the appropriate patient–provider transaction (i.e., transaction costs of access to health care) are potential barriers to accessing health care in low- and middle-income countries. This paper explores these transaction costs and their implications for health system governance through a cross-sectional survey of adult patients who received their first diagnosis of pulmonary tuberculosis (TB) at the three designated secondary health centres for TB care in Ebonyi State, Nigeria. The patients provided information on their care-seeking pathways and the associated costs prior to reaching the appropriate provider. Of the 452 patients, 84% first consulted an inappropriate provider. Only 33% of inappropriate consultations were with qualified providers (QP); the rest were with informal providers such as pharmacy providers (PPs; 57%) and traditional providers (TP; 10%). Notably, 62% of total transaction costs were incurred during the first visit to an inappropriate provider and the mean transaction costs incurred was highest with QPs (US$30.20) compared with PPs (US$14.40) and TPs (US$15.70). These suggest that interventions for reducing transaction costs should include effective decentralisation to integrate TB care with services at the primary health care level, community engagement to address information asymmetry, enforcing regulations to keep informal providers within legal limits and facilitating referral linkages among formal and informal providers to increase early contact with appropriate providers.

Electron Capture Dissociation of Divalent Metal-adducted Sulfated N-Glycans Released from Bovine Thyroid Stimulating Hormone

NASA Astrophysics Data System (ADS)

Zhou, Wen; Håkansson, Kristina

2013-11-01

Sulfated N-glycans released from bovine thyroid stimulating hormone (bTSH) were ionized with the divalent metal cations Ca2+, Mg2+, and Co by electrospray ionization (ESI). These metal-adducted species were subjected to infrared multiphoton dissociation (IRMPD) and electron capture dissociation (ECD) and the corresponding fragmentation patterns were compared. IRMPD generated extensive glycosidic and cross-ring cleavages, but most product ions suffered from sulfonate loss. Internal fragments were also observed, which complicated the spectra. ECD provided complementary structural information compared with IRMPD, and all observed product ions retained the sulfonate group, allowing sulfonate localization. To our knowledge, this work represents the first application of ECD towards metal-adducted sulfated N-glycans released from a glycoprotein. Due to the ability of IRMPD and ECD to provide complementary structural information, the combination of the two strategies is a promising and valuable tool for glycan structural characterization. The influence of different metal ions was also examined. Calcium adducts appeared to be the most promising species because of high sensitivity and ability to provide extensive structural information.

To identify and compare perceptions of RNs, registered dietitians (RDs), and patients regarding the best format and key nutrition information components that should be provided to patients during cancer treatment. Cross-sectional study using an opinion-based questionnaire. Outpatient cancer centers. 506 RNs and 367 RDs, as well as 653 patients undergoing cancer treatment. Two similar self-administered questionnaires were developed, one for patients and one for healthcare professionals. Face and content validity were assessed by a panel of experts. Data were analyzed using descriptive statistics, chi-square statistic, and a Spearman Correlation Coefficient to compare responses. Patient nutrition concerns as well as format and content of printed educational materials. Significant differences existed among groups regarding the most common nutrition concerns, the perception of importance of information frequently provided to patients with cancer, and rank order of importance for eight items typically provided to patients. The dietary information format preferred by all groups was an all-inclusive booklet; RNs (75%) were more likely than RDs (43%) or patients (50%) to prefer this format. Data also revealed that almost half of the patients (47%) received no dietary counseling, including 18% who experienced significant weight loss. RNs and RDs who provide nutrition education to patients with cancer should consider the need to develop and use a variety of printed materials to meet individual needs. Because major concerns of patients and healthcare professionals were related to patients ability to consume adequate amounts of food, this should be the primary focus of any nutrition education materials. These findings provide information that can be applied to the development of informational materials and counseling practices.

INFORMATION: THEORY, BRAIN, AND BEHAVIOR

PubMed Central

Jensen, Greg; Ward, Ryan D.; Balsam, Peter D.

2016-01-01

In the 65 years since its formal specification, information theory has become an established statistical paradigm, providing powerful tools for quantifying probabilistic relationships. Behavior analysis has begun to adopt these tools as a novel means of measuring the interrelations between behavior, stimuli, and contingent outcomes. This approach holds great promise for making more precise determinations about the causes of behavior and the forms in which conditioning may be encoded by organisms. In addition to providing an introduction to the basics of information theory, we review some of the ways that information theory has informed the studies of Pavlovian conditioning, operant conditioning, and behavioral neuroscience. In addition to enriching each of these empirical domains, information theory has the potential to act as a common statistical framework by which results from different domains may be integrated, compared, and ultimately unified.

SNP (single nucleotide polymorphism) is a popular tool for the study of genetic diversity, evolution, and other areas. Therefore, it is necessary to develop a convenient, utility, robust, rapid, and open source detecting-SNP tool for all researchers. Since the detection of SNPs needs special software and series steps including alignment, detection, analysis and present, the study of SNPs is limited for nonprofessional users. CsSNP (Comparative segments SNP, http://biodb.sdau.edu.cn/cssnp/ ) is a freely available web tool based on the Blat, Blast, and Perl programs to detect comparative segments SNPs and to show the detail information of SNPs. The results are filtered and presented in the statistics figure and a Gbrowse map. This platform contains the reference genomic sequences and coding sequences of 60 plant species, and also provides new opportunities for the users to detect SNPs easily. CsSNP is provided a convenient tool for nonprofessional users to find comparative segments SNPs in their own sequences, and give the users the information and the analysis of SNPs, and display these data in a dynamic map. It provides a new method to detect SNPs and may accelerate related studies.

The role of patient satisfaction in online health information seeking.

PubMed

Tustin, Nupur

2010-01-01

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.

The effective use of plant biomass for biofuel and bioproduct production requires a comprehensive glycosyl residue composition analysis to understand the different cell wall polysaccharides present in the different biomass sources. Here we compared four methods side-by-side for their ability to measure the neutral and acidic sugar composition of cell walls from herbaceous, grass, and woody model plants and bioenergy feedstocks. Arabidopsis, Populus , rice, and switchgrass leaf cell walls, as well as cell walls from Populus wood, rice stems, and switchgrass tillers, were analyzed by (1) gas chromatography-mass spectrometry (GC-MS) of alditol acetates combined with a total uronic acid assay; (2) carbodiimide reduction of uronic acids followed by GC-MS of alditol acetates; (3) GC-MS of trimethylsilyl (TMS) derivatives; and (4) high-pressure, anion-exchange chromatography (HPAEC). All four methods gave comparable abundance ranking of the seven neutral sugars, and three of the methods were able to quantify unique acidic sugars. The TMS, HPAEC, and carbodiimide methods provided comparable quantitative results for the specific neutral and acidic sugar content of the biomass, with the TMS method providing slightly greater yield of specific acidic sugars and high total sugar yields. The alditol acetate method, while providing comparable information on the major neutral sugars, did not provide the requisite quantitative information on the specific acidic sugars in plant biomass. Thus, the alditol acetate method is the least informative of the four methods. This work provides a side-by-side comparison of the efficacy of four different established glycosyl residue composition analysis methods in the analysis of the glycosyl residue composition of cell walls from both dicot (Arabidopsis and Populus ) and grass (rice and switchgrass) species. Both primary wall-enriched leaf tissues and secondary wall-enriched wood/stem tissues were analyzed for mol% and mass yield of the non-cellulosic sugars. The TMS, HPAEC, and carbodiimide methods were shown to provide comparable quantitative data on the nine neutral and acidic sugars present in all plant cell walls.

The Code of Health and Disability Services Consumers' Rights includes right 6: the "Right to be Fully Informed". Analysis of the Health and Disability Commissioners' opinions between 2008 and 2013 that have discussed right 6 shows that the duties on providers have increased in a number of areas: the need to inform of risks, including provider-inherent risks; open disclosure of adverse events; ongoing need to inform consumers throughout the therapeutic relationship; information of all available options; and provision of sufficient time between disclosure of information and obtaining informed consent for provision of health services. Following a breach opinion, the Human Rights Review Tribunal and the Health Practitioners Competency Tribunal, on occasion, have the opportunity to consider the case but their role in law development is limited compared with that of the Commissioner. The limitations of law development in this manner are discussed.

Statewide health information: a tool for improving hospital accountability.

PubMed

Epstein, M H; Kurtzig, B S

1994-07-01

By early 1994, 38 states had invested in data collection, analysis, and dissemination on the use, cost, effectiveness, and performance of hospitals. States use these data to control costs, encourage prudent purchasing, monitor effectiveness and outcomes of health care, guide health policy, and promote informed decision making. Experience in several states suggests that public release of hospital-specific data influences hospital performance. The value of state data organizations' databases to address issues of quality and accountability can be strengthened by ensuring the stability and growth of statewide health information systems, supporting research on information dissemination techniques, and promoting comparisons among hospitals. Information to measure provider performance must be placed in the public domain--to help ensure prudent and cost-effective health care purchasing and to give providers comparable information for improvement of care. State-level health databases are an essential component of the information infrastructure needed to support health reform.

Nativity and language preference as drivers of health information seeking: examining differences and trends from a U.S. population-based survey.

2017-12-01

To examine differences in health information seeking between U.S.-born and foreign-born populations in the U.S. Data from 2008 to 2014 from the Health Information National Trends Survey were used in this study (n = 15,249). Bivariate analyses, logistic regression, and predicted probabilities were used to examine health information seeking and sources of health information. Findings demonstrate that 59.3% of the Hispanic foreign-born population reported looking for health information, fewer than other racial/ethnic groups in the sample. Compared with non-Hispanic White, non-Hispanic Black (OR = 0.62) and Hispanic foreign-born individuals (OR = 0.31) were the least likely to use the internet as a first source for health information. Adjustment for language preference explains much of the disparity in health information seeking between the Hispanic foreign-born population and Whites; controlling for nativity, respondents who prefer Spanish have 0.25 the odds of using the internet as a first source of health information compared to those who prefer English. Foreign-born nativity and language preference are significant determinants of health information seeking. Further research is needed to better understand how information seeking patterns can influence health care use, and ultimately health outcomes. To best serve diverse racial and ethnic minority populations, health care systems, health care providers, and public health professionals must provide culturally competent health information resources to strengthen access and use by vulnerable populations, and to ensure that all populations are able to benefit from evolving health information sources in the digital age.

"Watch out for the gerbils, my child!" the role of maternal information on children's fear in an experimental setting using real animals.

Remmerswaal, Danielle; Muris, Peter; Huijding, Jorg

2013-06-01

Using an experimental approach, we examined the effects of verbal information as provided by the mothers on children's fear of real novel animals. Mothers of children aged 8 to 12 years (N=47) were shown a cage containing a pair of exotic rodents (i.e., Mongolian gerbils) and then received either positive or negative information about these animals. Mothers were told that their child would have to approach the animals and had the opportunity to prepare their children for this confrontation. Results showed that mothers spontaneously passed over the information they had received to their children. Most importantly, this information to some extent determined children's fear reactions towards the animals. That is, whereas no clear effects of information were found on subjective fear ratings, the data did indicate that children of mothers in the negative information condition were more reluctant to approach the animals as compared to children of mothers who had received positive information. The findings provide further support for the idea that verbal information as provided by parents may induce fear in their offspring. Copyright © 2013. Published by Elsevier Ltd.

Patterns of Health Information Technology Use according to Sexual Orientation among US Adults Aged 50 and Older: Findings from a National Representative Sample-National Health Interview Survey 2013-2014.

Health disparities among sexual minority adults ages 50 and older have been documented. Factors such as lifetime discrimination and internalized stigma may deter sexual minority individuals from seeking health services. Several studies suggest that health information technology may facilitate health education and outreach to populations whose health behaviors are affected by stigma such as older sexual minority people. This study examined the role of sexual minority identity as a factor that is associated with health information technology use. Data from the 2013-2014 National Health Interview Survey (NHIS) were analyzed. Multivariate logistic regressions were used to compare the odds of using technology as a resource for health information between sexual minority versus heterosexual US adults aged 50 and older. Adjusting for sociodemographic variables and health variables, sexual minority participants had increased odds of using computers to look up health information on the Internet (OR = 2.01, 95% CI 1.53-2.64), using computers to fill a prescription (OR = 1.97, 95% CI 1.36-2.85), and using computers to communicate with health-care provider by e-mail (OR = 2.13, 95% CI 1.55-2.92), compared with heterosexuals. Findings reveal greater use of health information technology among older sexual minority adults when compared to their heterosexual counterparts. While sensitive, competent providers and culturally appropriate prevention services are essential to meeting the needs of aging sexual minority populations, health information technology use may be an innovative means of reducing disparities in information access as structural changes are implemented.

Advice on drug safety in pregnancy: are there differences between commonly used sources of information?

Frost Widnes, Sofia K; Schjøtt, Jan

2008-01-01

Safety regarding use in pregnancy is not established for many drugs. Inconsistencies between sources providing drug information can give rise to confusion with possible therapeutic consequences. Therefore, it is important to measure clinically important differences between drug information sources. The objective of this study was to compare two easily accessible Norwegian sources providing advice on drug safety in pregnancy - the product monographs in the Felleskatalog (FK), published by the pharmaceutical companies, and the five regional Drug Information Centres (DICs) in Norway - in addition to assessing the frequency of questions regarding drug safety in pregnancy made to the DICs according to the Anatomical Therapeutic Chemical (ATC) classification system. Advice on drug use in pregnancy provided by the DICs in 2003 and 2005 were compared with advice in the product monographs for the respective drugs in the FK. Comparison of advice was based on categorization to one of four categories: can be used, benefit-risk assessment, should not be used, or no available information. A total of 443 drug advice were categorized. Seven out of ten of drugs frequently enquired about, according to the ATC system, were drugs acting on the nervous system (group N). For 208 (47%) of the drugs, advice differed between the DICs and FK. Advice from the FK was significantly (p < 0.01) more restrictive than advice from the DICs. There were no differences in the level of consistency of advice between drugs that were newly introduced and those that had been on the market for a longer time, advice regarding use of drugs in the first trimester and advice regarding use of drugs in the second or third trimester, or between advice provided during 2003 and during 2005. The results of this study show considerable differences between two Norwegian sources providing advice on the use of drugs in pregnancy. Based on the knowledge that healthcare providers choose sources of information in a random manner, our results may be of clinical importance. We believe that the problem with heterogeneous drug information on this subject is not confined to Norway and that our results should be of international interest.

Five hundred caregivers were recruited in a 5-week period to complete an online survey of demographic characteristics, Internet use, online health-seeking self-efficacy, and ways they used the Internet to support PLWHA. Caregivers were on average 39 years old, white, heterosexual, highly educated, and Internet-savvy. Most provided informal care only (e.g., as a friend; 78%), with the remainder divided among those who provided care exclusively as part of their job (11%) or in both informally and professionally (11%). Most (72%) respondents visited a general medical website for HIV information, and 44% shared information from the Internet with PLWHA. Compared to informal caregivers, caregivers whose roles were both informal and professional had greater odds of recently sharing information from the Internet with PLWHA (odds ratio [OR] = 2.03) and ever printing off information from a website to give to PLWHA (odds ratio [OR] = 3.87). Professional caregivers had higher odds of ever printing off information from a website to give to PLWHA (OR = 1.87), but lower odds of sending an e-mail with a website link (OR = 0.32) than informal caregivers. These findings suggest that websites providing HIV-related resources should consider the various ways in which caregivers use their content, and how utilization differs by role. More research is needed to understand how people providing care for PLWHA share information and support each other and the impact that doing so has on caregiver burden and treatment outcomes for PLWHA.

Anthropometry has been widely used in different fields, providing relevant information for medicine, ergonomics and biometric applications. However, the existent solutions present marked disadvantages, reducing the employment of this type of evaluation. Studies have been conducted in order to easily determine anthropometric measures considering data provided by low-cost sensors, such as the Microsoft Kinect. In this work, a methodology is proposed and implemented for estimating anthropometric measures considering the information acquired with this sensor. The measures obtained with this method were compared with the ones from a validation system, Qualisys. Comparing the relative errors determined with state-of-art references, for some of the estimated measures, lower errors were verified and a more complete characterization of the whole body structure was achieved.

CSGRqtl: A Comparative Quantitative Trait Locus Database for Saccharinae Grasses.

PubMed

Zhang, Dong; Paterson, Andrew H

2017-01-01

Conventional biparental quantitative trait locus (QTL) mapping has led to some successes in the identification of causal genes in many organisms. QTL likelihood intervals not only provide "prior information" for finer-resolution approaches such as GWAS but also provide better statistical power than GWAS to detect variants with low/rare frequency in a natural population. Here, we describe a new element of an ongoing effort to provide online resources to facilitate study and improvement of the important Saccharinae clade. The primary goal of this new resource is the anchoring of published QTLs for this clade to the Sorghum genome. Genetic map alignments translate a wealth of genomic information from sorghum to Saccharum spp., Miscanthus spp., and other taxa. In addition, genome alignments facilitate comparison of the Saccharinae QTL sets to those of other taxa that enjoy comparable resources, exemplified herein by rice.

This pilot study with tobacco merchants asked how policy practices may influence sales of tobacco to youth. This study compared tobacco merchant new employee training and business policies and practices to business compliance data. Licensed tobacco merchants in a rural Minnesota county were mailed surveys regarding their new employee training and business policies practices. The returned surveys (75.9%, N = 44) were compared with tobacco compliance results that indicated if the business sold tobacco to youth during a county compliance check. The major finding from this study was that the survey respondents who did not sell tobacco to youth provided training on fake identification cards (68.0%, n = 17). Tobacco merchants who provided additional information on fake identification cards (40%,n = 6), chi(2)(2, n = 43) 6.66, p = .036, were more likely to not sell tobacco to youth than the merchants who did not provide fake identification card information.

Previous surveys showed a poor quality of the web sites providing health information about low back pain. However, the rapid and continuous evolution of the Internet content may question the current validity of those investigations. The present study is aimed to quantitatively assess the quality of the Internet information about low back pain retrieved with the most commonly employed search engines. An Internet search with the keywords "low back pain" has been performed with Google, Yahoo!® and Bing™ in the English language. The top 30 hits obtained with each search engine were evaluated by five independent raters and averaged following criteria derived from previous works. All search results were categorized as declaring compliant to a quality standard for health information (e.g. HONCode) or not and based on the web site type (Institutional, Free informative, Commercial, News, Social Network, Unknown). The quality of the hits retrieved by the three search engines was extremely similar. The web sites had a clear purpose, were easy to navigate, and mostly lacked in validity and quality of the provided links. The conformity to a quality standard was correlated with a marked greater quality of the web sites in all respects. Institutional web sites had the best validity and ease of use. Free informative web sites had good quality but a markedly lower validity compared to Institutional websites. Commercial web sites provided more biased information. News web sites were well designed and easy to use, but lacked in validity. The average quality of the hits retrieved by the most commonly employed search engines could be defined as satisfactory and favorably comparable with previous investigations. Awareness of the user about checking the quality of the information remains of concern.

Recent, rapid radiations make species-level phylogenetics difficult to resolve. We used a multiplexed, high-throughput sequencing approach to identify informative genomic regions to resolve phylogenetic relationships at low taxonomic levels in Begonia from a survey of sixteen species. A long-range PCR method was used to generate draft plastid genomes to provide a strong phylogenetic backbone, identify fast evolving regions and provide informative molecular markers for species-level phylogenetic studies in Begonia.

2007-10-01

The information provided on package inserts and inner wrapping of eight products containing Panax ginseng from different manufacturers was compared internally and checked against data from the scientific literature. The inserts included extensive text, containing abundant information on indications for use, but no scientific evidence in humans. All the inserts lacked information on potential adverse effects and drug interaction. There was no standardization as to dose regimens, particularly in relation to the dried extract and ginsenoside concentration. The eight inserts thus showed no concern over standardization, indication for usage, or possible side effects and drug interactions.

Gathering patient information to contain an outbreak of Listeria monocytogenes is difficult because of the patients' severe illness or death. Extending the range of interviewees to acquire epidemiological data can thus be important to maximise information. We built the current analysis on a case-case outbreak investigation conducted during a Swiss listeriosis outbreak between 30 January and 11 May 2014, including 31 patients with confirmed L. monocytogenes infection. We interviewed treating physicians and patients or their next of kin to gather information on clinical aspects, eating habits and food consumption. We compared the different information sources with regards to their potential to provide specific, complete and rapid information on the affected population and their food consumption history. We obtained a 100% response rate among physicians, providing detailed information on the affected population by describing health status, underlying conditions, and signs and symptoms. Detailed information on food history could not be obtained from physicians, making the information vague and unspecific. Less than 50% of patients could be interviewed, limiting our information base. Nevertheless, patient information on the food history was sufficiently detailed and helped to identify the outbreak source CONCLUSIONS: Outbreak investigation teams confronted with limited information from patients and with small numbers of cases can enhance information on the affected population and the outbreak source by combining information from physicians and patients. Physicians provided comprehensive information on signs and symptoms, underlying conditions and the general health status. Patients remain vital to provide detailed information on the food consumption history.

Characterize frequency and type of health and nutrient content claims in prime-time weeknight Spanish- and English-language television advertisements from programs shown in 2003 with a high viewership by women aged 18 to 35 years. Comparative content analysis design was used to analyze 95 hours of Spanish-language and 72 hours of English-language television programs (netting 269 and 543 food ads, respectively). A content analysis instrument was used to gather information on explicit health and nutrient content claims: nutrition information only; diet-disease; structure-function; processed food health outcome; good for one's health; health care provider endorsement. Chi-square statistics detected statistically significant differences between the groups. Compared to English-language television, Spanish-language television aired significantly more food advertisements containing nutrition information and health, processed food/health, and good for one's health claims. Samples did not differ in the rate of diet/disease, structure/function, or health care provider endorsement claims. Findings indicate that Spanish-language television advertisements provide viewers with significantly more nutrition information than English-language network advertisements. Potential links between the deteriorating health status of Hispanics acculturating into US mainstream culture and their exposure to the less nutrition-based messaging found in English-language television should be explored.

With increased attention to patient privacy and autonomy, privacy protection and information provision for patients are becoming increasingly important. The aim of this study was to identify and analyse nurses' and patients' perceptions of the importance and performance of protecting patients' privacy and providing them with relevant information. This study is a descriptive cross-sectional investigation. Participants and research context: Participants were 168 patients hospitalised in medical and surgical wards and 176 nurses who cared for them. Ethical consideration: This study was approved by the Chung-Ang University Bioethics Committee, and informed written consent was collected from all participants. Nurses' recognition of the importance of protecting patients' privacy and providing adequate information was higher compared to their actual performance, and the nurses' level of performance was higher in comparison with the patients' recognition of its importance. Although a holistic approach to patient privacy protection and information provision is needed, the medical field has not embraced this model of care. These findings provide empirical data to create an ethical environment for the future, as considerable attention has been devoted to patients' rights and medical institutions' liability for providing explanations to patients.

Little cigars, big cigars: omissions and commissions of harm and harm reduction information on the Internet.

PubMed

Dollar, Katherine M; Mix, Jacqueline M; Kozlowski, Lynn T

2008-05-01

We conducted a comparative analysis of "harm," "harm reduction," and "little cigar" information about cigars on 10 major English-language health Web sites. The sites were from governmental and nongovernmental organizations based in seven different countries and included "harm" and "harm reduction" information, discussions of little cigars, quantitative estimates of health risks, and qualifying behavioral characteristics (inhalation, number per day). Of the 10 Web sites, 7 offered statements explicitly indicating that cigars may be safer than cigarettes. None of the Web sites reviewed described that little cigars are likely as dangerous as cigarettes. Some Web sites provided quantitative estimates of health risks and extensive discussions of qualifying factors. Reading grade levels were higher than desirable. Extensive and complex information on the reduced risks of cigars compared with cigarettes is available on Web sites affiliated with prominent health organizations. Yet these sites fail to warn consumers that popular cigarette-like little cigars and cigarillos are likely to be just as dangerous as cigarettes, even for those who have never smoked cigarettes. Improvement of these Web sites is urgently needed to provide the public with high-quality health information.

2001-01-01

This paper presents initial findings of a research study designed to provide insight into the issue of intent information exchange in constrained en-route air-traffic operations and its effect on pilot decision making and flight performance. The piloted simulation was conducted in the Air Traffic Operations Laboratory at the NASA Langley Research Center. Two operational modes for autonomous operations were compared under conditions of low and high operational complexity. The tactical mode was characterized primarily by the use of state information for conflict detection and resolution and an open-loop means for the pilot to meet operational constraints. The strategic mode involved the combined use of state and intent information, provided the pilot an additional level of alerting, and allowed a closed-loop approach to meeting operational constraints. Operational constraints included separation assurance, schedule adherence, airspace hazard avoidance, flight efficiency, and passenger comfort. Potential operational benefits of both modes are illustrated through several scenario case studies. Subjective pilot ratings and comments comparing the tactical and strategic modes are presented.

Fusion of light-field and photogrammetric surface form data

Photogrammetry based systems are able to produce 3D reconstructions of an object given a set of images taken from different orientations. In this paper, we implement a light-field camera within a photogrammetry system in order to capture additional depth information, as well as the photogrammetric point cloud. Compared to a traditional camera that only captures the intensity of the incident light, a light-field camera also provides angular information for each pixel. In principle, this additional information allows 2D images to be reconstructed at a given focal plane, and hence a depth map can be computed. Through the fusion of light-field and photogrammetric data, we show that it is possible to improve the measurement uncertainty of a millimetre scale 3D object, compared to that from the individual systems. By imaging a series of test artefacts from various positions, individual point clouds were produced from depth-map information and triangulation of corresponding features between images. Using both measurements, data fusion methods were implemented in order to provide a single point cloud with reduced measurement uncertainty.

The telecare medicine information system enables the patients gain health monitoring at home and access medical services over internet or mobile networks. In recent years, the schemes based on cryptography have been proposed to address the security and privacy issues in the telecare medicine information systems. However, many schemes are insecure or they have low efficiency. Recently, Awasthi and Srivastava proposed a three-factor authentication scheme for telecare medicine information systems. In this paper, we show that their scheme is vulnerable to the reflection attacks. Furthermore, it fails to provide three-factor security and the user anonymity. We propose a new three-factor authentication scheme for the telecare medicine information systems. Detailed analysis demonstrates that the proposed scheme provides mutual authentication, server not knowing password and freedom of password, biometric update and three-factor security. Moreover, the new scheme provides the user anonymity. As compared with the previous three-factor authentication schemes, the proposed scheme is more secure and practical.

This article examines the reporting of Consumer Assessment of Healthcare Providers and Systems (CAHPSO) consumer experience data by sponsors, those that fund data collection and decide how information is summarized and disseminated. We found that sponsors typically publicly reported comparative data to consumers, employers, and/or purchasers. They presented health plan-level data in print and online at least annually, usually in combination with non-CAHPS information. Many provided trend data, comparisons to individual plans, and summary scores. Most shared information consistent with known successful reporting practices. Areas meriting attention include: tailoring reports to specific audiences, assessing literacy, planning dissemination, educating vendors, and evaluating products and programs.

Providing patients with information about disease-modifying anti-rheumatic drugs: Individually or in groups? A pilot randomized controlled trial comparing adherence and satisfaction.

2009-06-01

Communicating information about disease-modifying anti-rheumatic drugs (DMARDs) before patients start treatment is a key role for some rheumatology clinical nurse specialists. This is done in our unit to promote understanding of the risks and benefits of drug therapy and encourage timely and reliable use of DMARDs. Information is routinely provided individually but this can lead to delays in starting treatment because of limited nursing resources. In this randomized trial we tested the feasibility of giving patients, who were about to start on a DMARD, information about the drug in groups and compared this with information given individually. Adults with a clinical diagnosis of rheumatoid arthritis or psoriatic arthritis who were referred to the nursing team for counselling about starting on methotrexate, sulfasalazine or leflunomide were included. Patients who had previously taken a DMARD were not excluded and those consenting were randomized to receive drug information individually or in groups (of three to six patients). We provided all patients with written materials about the relevant drug and discussed the risks and benefits of drug use verbally. Patients allocated to group counselling received this intervention in a teaching room, with a slide presentation. The primary outcome was adherence with medication use, ascertained by pill counts, self-report diaries and prescription dispensation. Secondary outcomes included satisfaction with information about medicines (SIMS) by questionnaire; time taken to provide information; adherence to scheduled hospital appointments and blood monitoring schedules; and DMARD continuation rates at four and twelve months. Of 127 eligible patients referred for counselling about DMARDs, 62 consented to take part: 32 were randomized to receive drug information individually and 30 to receiving it in groups. Patients allocated to the two different interventions were comparable for age and diagnoses at baseline but more patients allocated individual counselling had not taken a DMARD previously: 56% (18/32) versus 20% (6/30). More patients counselled in groups were adherent (27/30; 90%) compared with patients counselled individually (22/32; 69%; p = 0.06) by pill counts. However, on self-report diaries, similar proportions were adherent (group counselling 97% (29/30) versus individual 94% (30/32); p = 1.0). All but two prescriptions were dispensed. More patients allocated to individual counselling missed at least one blood monitoring visit (25% versus 17%; p = 0.54) and at least one scheduled clinic visit (19% versus 3%; p = 0.10). SIMS scores indicated high levels of patient satisfaction and were similar for both groups. The time taken to run group and individual counselling sessions were similar (median of 35 minutes versus 33 minutes, respectively). Nursing time per individual patient in those allocated group counselling was 11.6 minutes. Drug continuation rates were higher for those counselled in groups compared with those counselled individually: at four months, 73% versus 63 %; p = 0.42; at twelve months, 47% versus 38%; p = 0.61). Our pilot study demonstrated the feasibility of providing counselling on DMARDs to groups of patients with important time savings for specialist nurses and while maintaining high levels of patient satisfaction. There was a trend for better outcomes in terms of adherence and drug continuation rates for patients counselled in groups, indicating potential benefits from group interactions. However, these findings need to be investigated further in a larger, fully powered trial. 2008 John Wiley & Sons, Ltd.

Behavioral response to contamination risk information in a spatially explicit groundwater environment: Experimental evidence

NASA Astrophysics Data System (ADS)

Li, Jingyuan; Michael, Holly A.; Duke, Joshua M.; Messer, Kent D.; Suter, Jordan F.

2014-08-01

This paper assesses the effectiveness of aquifer monitoring information in achieving more sustainable use of a groundwater resource in the absence of management policy. Groundwater user behavior in the face of an irreversible contamination threat is studied by applying methods of experimental economics to scenarios that combine a physics-based, spatially explicit, numerical groundwater model with different representations of information about an aquifer and its risk of contamination. The results suggest that the threat of catastrophic contamination affects pumping decisions: pumping is significantly reduced in experiments where contamination is possible compared to those where pumping cost is the only factor discouraging groundwater use. The level of information about the state of the aquifer also affects extraction behavior. Pumping rates differ when information that synthesizes data on aquifer conditions (a "risk gauge") is provided, despite invariant underlying economic incentives, and this result does not depend on whether the risk information is location-specific or from a whole aquifer perspective. Interestingly, users increase pumping when the risk gauge signals good aquifer status compared to a no-gauge treatment. When the gauge suggests impending contamination, however, pumping declines significantly, resulting in a lower probability of contamination. The study suggests that providing relatively simple aquifer condition guidance derived from monitoring data can lead to more sustainable use of groundwater resources.

The Wisconsin Immunization Registry is a confidential, web-based system used since 1999 as a centralized repository of immunization information for Wisconsin residents. Provide evidence based on Registry experiences with electronic data exchange, comparing the benefits and drawbacks of using the Health Level 7 standard, including the option for real time data exchange vs the flat file method. For data regarding vaccinations received by children aged 4 months through 6 years with Wisconsin addresses that were submitted to the Registry during 2010 and 2011, data timeliness (days from vaccine administration to date information was received) and completeness (percentage of records received that include core data elements for electronic storage) were compared by file submission method. Data submitted using Health Level 7 were substantially more timely than data submitted using the flat file method. Additionally, data submitted using Health Level 7 were substantially more complete for each of the core elements compared to flat file submission. Health care organizations that submit electronic data to immunization information systems should be aware that the technical decision to use the Health Level 7 format, particularly if real-time data exchange is employed, can result in more timely and accurate data. This will assist clinicians in adhering to the Advisory Committee on Immunization Practices schedule and reducing over-immunization.

1995-03-01

The Adult Personality Functioning Assessment (APFA) provides ratings of interpersonal and social role performance in six domains over substantial periods of time. Ratings based on subject and informant accounts using the APFA were compared. There was good agreement for estimates of levels of dysfunction, and moderate agreement for type of dysfunction. An anticipated under-reporting of difficulties by subjects was not found. The extent of personality dysfunction was predictive of whether a close informant was available; however, closeness of informant was not consistently associated with subject-informant agreement.

Objectives The aim of the study was to develop a metadata and ontology-based health information search engine ensuring semantic interoperability to collect and provide health information using different application programs. Methods Health information metadata ontology was developed using a distributed semantic Web content publishing model based on vocabularies used to index the contents generated by the information producers as well as those used to search the contents by the users. Vocabulary for health information ontology was mapped to the Systematized Nomenclature of Medicine Clinical Terms (SNOMED CT), and a list of about 1,500 terms was proposed. The metadata schema used in this study was developed by adding an element describing the target audience to the Dublin Core Metadata Element Set. Results A metadata schema and an ontology ensuring interoperability of health information available on the internet were developed. The metadata and ontology-based health information search engine developed in this study produced a better search result compared to existing search engines. Conclusions Health information search engine based on metadata and ontology will provide reliable health information to both information producer and information consumers. PMID:24872907

Methodological development of topographic correction in 2D/3D ToF-SIMS images using AFM images

NASA Astrophysics Data System (ADS)

Jung, Seokwon; Lee, Nodo; Choi, Myungshin; Lee, Jungmin; Cho, Eunkyunng; Joo, Minho

2018-02-01

Time-of-flight secondary-ion mass spectrometry (ToF-SIMS) is an emerging technique that provides chemical information directly from the surface of electronic materials, e.g. OLED and solar cell. It is very versatile and highly sensitive mass spectrometric technique that provides surface molecular information with their lateral distribution as a two-dimensional (2D) molecular image. Extending the usefulness of ToF-SIMS, a 3D molecular image can be generated by acquiring multiple 2D images in a stack. These imaging techniques by ToF-SIMS provide an insight into understanding the complex structures of unknown composition in electronic material. However, one drawback in ToF-SIMS is not able to represent topographical information in 2D and 3D mapping images. To overcome this technical limitation, topographic information by ex-situ technique such as atomic force microscopy (AFM) has been combined with chemical information from SIMS that provides both chemical and physical information in one image. The key to combine two different images obtained from ToF-SIMS and AFM techniques is to develop the image processing algorithm, which performs resize and alignment by comparing the specific pixel information of each image. In this work, we present methodological development of the semiautomatic alignment and the 3D structure interpolation system for the combination of 2D/3D images obtained by ToF-SIMS and AFM measurements, which allows providing useful analytical information in a single representation.

Delivering Breast Reconstruction Information to Patients: Women Report on Preferred Information Delivery Styles and Options.

Webb, Carmen; Sharma, Vishal; Temple-Oberle, Claire

2018-02-01

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.

Enhancing patient autonomy through peer review to replace the FDA's rigorous approval process.

2012-10-01

There may once have been a time when doctors unquestioningly accepted the government's declaration of a drug's effectiveness and when patients unquestioningly accepted the prescriptions of their doctors. That time has passed. Now, information--good and bad--showers from all directions on patients and physicians alike. A filter is needed, and peer review provides the best one. But who or what is this validated information for? Ethically, its primary purpose is to enable patients to make decisions consistent with their values. Providing vetted information in a form that is useful to patients requires an emphasis on comprehensible, comprehensive, trustworthy, verifiable, and transparent communication. The hypothetical comparative effectiveness case study in this month's Health Affairs does not appear to rise to the level that would be helpful to providers or patients.

How the Recovery Act's Federal Coordinating Council paved the way for the Patient-Centered Outcomes Research Institute.

Conway, Patrick H

2010-11-01

The American Recovery and Reinvestment Act of 2009 provided $1.1 billion for comparative effectiveness research and established the Federal Coordinating Council for Comparative Effectiveness Research to direct that investment. The council laid a critical foundation for comparative effectiveness research in the steps it took to gather information, invite public input, set priorities, coordinate project solicitations, and stress the importance of evaluating research investments. Although the council has been superseded by a successor--the Patient-Centered Outcomes Research Institute--the experiences of the council can and should inform the work of the new institute as it begins its operations.

Improving uptake and use of malaria rapid diagnostic tests in the context of artemisinin drug resistance containment in eastern Myanmar: an evaluation of incentive schemes among informal private healthcare providers.

As efforts to contain artemisinin resistance and eliminate Plasmodium falciparum intensify, the accurate diagnosis and prompt effective treatment of malaria are increasingly needed in Myanmar and the Greater Mekong Sub-region (GMS). Rapid diagnostic tests (RDTs) have been shown to be safe, feasible, and effective at promoting appropriate treatment for suspected malaria, which are of particular importance to drug resistance containment. The informal private sector is often the first point of care for fever cases in malaria endemic areas across Myanmar and the GMS, but there is little published information about informal private provider practices, quality of service provision, or potential to contribute to malaria control and elimination efforts. This study tested different incentives to increase RDT use and improve the quality of care among informal private healthcare providers in Myanmar. The study randomized six townships in the Mon and Shan states of rural Myanmar into three intervention arms: 1) RDT price subsidies, 2) price subsidies with product-related financial incentives, and 3) price subsidies with intensified information, education and counselling (IEC). The study assessed the uptake of RDT use in the communities by cross-sectional surveys of 3,150 households at baseline and six months post-intervention (6,400 households total, 832 fever cases). The study also used mystery clients among 171 providers to assess quality of service provision across intervention arms. The pilot intervention trained over 600 informal private healthcare providers. The study found a price subsidy with intensified IEC, resulted in the highest uptake of RDTs in the community, as compared to subsidies alone or merchandise-related financial incentives. Moreover, intensified IEC led to improvements in the quality of care, with mystery client surveys showing almost double the number of correct treatment following diagnostic test results as compared to a simple subsidy. Results show that training and quality supervision of informal private healthcare providers can result in improved demand for, and appropriate use of RDTs in drug resistance containment areas in eastern Myanmar. Future studies should assess the sustainability of such interventions and the scale and level of intensity required over time as public sector service provision expands.

Teratology Information Services (TIS) provide health care professionals and the public with information regarding the safety and/or risk of exposures during pregnancy and lactation, mainly via telephone consultations. An international comparison of clinical practices at TIS has never been conducted. The survey objective was to compare international TIS to North American TIS, with an aim to identify strengths and challenges that can lead to service improvement. Twenty-two international TIS were approached for participation during an international conference. TIS were surveyed on information in six categories: services, staffing, operations, data collection, knowledge transfer activities and additional information. Data were summarized using descriptive statistics. Statistical tests were conducted using SPSS®. Sixteen TIS from 12 countries participated. Survey results were compared with previously reported results from a similar survey of North American TIS (16 US, two Canadian). TIS exist in a variety of departments and settings, but most commonly are in university hospitals. Pregnant women were the most commonly counselled group worldwide. International TIS spent significantly more time fielding inquiries regarding medications, while North American TIS had a wider variety of inquiry categories. All TIS could improve budget tracking. Overall, service practices and goals were similar, although international TIS conducted more follow-up with service users than North American TIS. This report offers TIS the first ever opportunity to compare practices. Increased dialogue between TIS encourages sharing of best practices and improves the ability of these important public health programmes to support women and health care providers. © 2010 Blackwell Publishing Ltd.

Effect of antidepressant medication use on emotional information processing in major depression.

Wells, Tony T; Clerkin, Elise M; Ellis, Alissa J; Beevers, Christopher G

2014-02-01

Acute administration of antidepressant medication increases emotional information processing for positive information in both depressed and healthy persons. This effect is likely relevant to the therapeutic actions of these medications, but it has not been studied in patients with major depressive disorder taking antidepressants as typically prescribed in the community. The authors used eye tracking to examine the effects of antidepressant medication on selective attention for emotional stimuli in a sample of 47 patients with major depressive disorder (21 medicated and 26 unmedicated) and 47 matched comparison subjects without depression. Participants completed a passive-viewing eye-tracking task assessing selective attention for positive, dysphoric, threatening, and neutral stimuli in addition to providing medication information and self-report measures of depression and anxiety severity. Depressed participants currently taking antidepressants and nondepressed comparison subjects demonstrated greater total gaze duration and more fixations for positive stimuli compared with unmedicated depressed participants. Depressed participants on medication also had fewer fixations for dysphoric stimuli compared with depressed participants not on medication. Antidepressants, as prescribed in the community to patients with depression, appear to modify emotional information processing in the absence of differences in depression severity. These results are consistent with previous work and indicate a robust effect for antidepressants on positive information processing. They also provide further evidence for modification of information processing as a potential mechanism of action for antidepressant medication.

Capturing Accurate and Useful Information on Medication-Related Telenursing Triage Calls.

Registered nurses providing telenursing triage and advice services record information on the medication related calls they handle. However the quality and consistency of these data were rarely examined. Our aim was to examine medication related calls made to the healthdirect advice service in November 2014, to assess their basic characteristics and how the data entry format influenced information collected and data consistency. Registered nurses selected the patient question type from a range of categories, and entered the medications involved in a free text field. Medication names were manually extracted from the free text fields. We also compared the selected patient question type with the free text description of the call, in order to gauge data consistency. Results showed that nurses provided patients with advice on medication-related queries in a timely matter (the median call duration of 9 minutes). From 1835 calls, we were able to identify and classify 2156 medications into 384 generic names. However, in 204 cases (11.2% of calls) no medication name was entered. A further 308 (15.0%) of the medication names entered were not identifiable. When we compared the selected patient question with the free text description of calls, we found that these were consistent in 63.27% of cases. Telenursing and triage advice services provide a valuable resource to the public with quick and easily accessible advice. To support nurses provide quality services and record accurate information about the queries, appropriate data entry format and design would be beneficial.

Prefrontal Neural Activity When Feedback Is Not Relevant to Adjust Performance

PubMed Central

Özyurt, Jale; Rietze, Mareike; Thiel, Christiane M.

2012-01-01

It has been shown that the rostral cingulate zone (RCZ) in humans uses both positive and negative feedback to evaluate performance and to flexibly adjust behaviour. Less is known on how the feedback types are processed by the RCZ and other prefrontal brain areas, when feedback can only be used to evaluate performance, but cannot be used to adjust behaviour. The present fMRI study aimed at investigating feedback that can only be used to evaluate performance in a word-learning paradigm. One group of volunteers (N = 17) received informative, performance-dependent positive or negative feedback after each trial. Since new words had to be learnt in each trial, the feedback could not be used for task-specific adaptations. The other group (N = 17) always received non-informative feedback, providing neither information about performance nor about possible task-specific adaptations. Effects of the informational value of feedback were assessed between-subjects, comparing trials with positive and negative informative feedback to non-informative feedback. Effects of feedback valence were assessed by comparing neural activity to positive and negative feedback within the informative-feedback group. Our results show that several prefrontal regions, including the pre-SMA, the inferior frontal cortex and the insula were sensitive to both, the informational value and the valence aspect of the feedback with stronger activations to informative as compared to non-informative feedback and to informative negative compared to informative positive feedback. The only exception was RCZ which was sensitive to the informational value of the feedback, but not to feedback valence. The findings indicate that outcome information per se is sufficient to activate prefrontal brain regions, with the RCZ being the only prefrontal brain region which is equally sensitive to positive and negative feedback.

To design and establish a uterine fibroid (UF) registry based in the United States (US) to provide comparative effectiveness data regarding UF treatment. We report here the design and initial recruitment for the Comparing Options for Management: Patient-centered Results for Uterine Fibroids (COMPARE-UF) registry (Clinicaltrials.gov, NCT02260752), funded by the Agency for Healthcare Research and Quality (AHRQ) in collaboration with the-Patient-Centered Outcomes Research Institute (PCORI). COMPARE-UF is designed to help answer critical questions about treatment options for women with symptomatic UF. Women undergoing a procedure for UF (hysterectomy, myomectomy [abdominal, hysteroscopic, vaginal and laparoscopic/robotic], endometrial ablation, radiofrequency fibroid ablation, uterine artery embolization, magnetic resonance guided focused ultrasound or progestin-releasing intrauterine device insertion) at one of the COMPARE-UF sites are invited to participate in a prospective registry with three years follow-up for post-procedural outcomes. Enrolled participants provide annual follow-up through an online portal or through traditional phone contact. A central data abstraction center provides information obtained from imaging, operative or procedural notes and pathology reports. Women with uterine fibroids and other stakeholders are a key part of the COMPARE-UF registry and participate at all points from study design to dissemination of results. We built a network of nine clinical sites across the US with expertise in the care of women with UF to capture geographic, racial, ethnic and procedural diversity. Of the initial 2031 women enrolled in COMPARE-UF, 42% are self-identified as Black or African-American and 40% are age 40 years or younger with 16% of participants under age 35. Women undergoing myomectomy comprise the largest treatment group at 46% of all procedures with laparoscopic or robotic myomectomy comprising the largest subset of myomectomies at 19% of all procedures. Hysterectomy is the second most common treatment within the registry at 38%. In response to priorities identified by our patient stakeholders, the initial aims within COMPARE-UF will address how different procedures used to treat UF compare in terms of long-lasting symptom relief, potential for recurrence, medical complications, improvement in quality of life and sexual function, age at menopause, and fertility and pregnancy outcomes. COMPARE-UF will generate evidence on the comparative effectiveness of different procedural options for UF, in order to help patients and their caregivers make informed decisions that best meet an individual patient's short- and long-term preferences. Building upon this infrastructure, the COMPARE-UF team of investigators and stakeholders, including patients, collaborate to identify future priorities for expanding the registry, such assessing the efficacy of medical therapies for UF. COMPARE-UF results will be disseminated directly to patients, providers, and other stakeholders using traditional academic pathways, as well as innovative methods, including a variety of social media platforms. Given demographic differences among women undergoing different UF treatments, assessing comparative effectiveness for this disease through clinical trials will remain difficult. Therefore, this registry provides optimized evidence to help patients and their providers better understand the pros and cons of different treatment options so that they can make more informed decisions.

Disparities between online assisted reproduction patient education for same-sex and heterosexual couples.

PubMed

Jin, Helen; Dasgupta, Shoumita

2016-10-01

Does the prevalence of online education in fertility center websites differ for lesbian, gay, bisexual, transgender (LGBT) couples compared to online education for heterosexual couples? This review of fertility center websites showed that the majority of websites with patient education for heterosexual couples do not have similar materials for LGBT couples. In order to have biologically related children, LGBT individuals or couples utilize assisted reproductive technologies (ART). Fertility clinic websites provide online education to familiarize patients with the different ART procedures; however, no studies have examined the prevalence of educational information for LGBT couples compared to information for heterosexual couples utilizing ART. This website review evaluated Centers for Disease Control and Prevention (CDC)-reported fertility center websites. Websites were reviewed in 2014 using the latest 2011 CDC report, and reviewed again in 2015 with the latest 2013 CDC report. Patient education information was coded using categories determined after a sample review, and differences were analyzed with χ(2) tests, with P-values calculated with Fisher's exact test. In 2014, 31.1% (121) of 389 websites with information for heterosexual couples also contained information for LGBT couples. In 2015, the number of fertility centers with information for LGBT couples increased by 52.9% to 185 (P < 0.001) of 407 (45.5%) fertility center websites. However, the majority of fertility clinic websites (54.5%) with information for heterosexual couples still do not include information specific to LGBT couples. The lack of online information on fertility center websites may not directly reflect the quality of care LGBT individuals or couples receive in the clinic, and the effect of this absence of online information on the clinical experiences of LGBT patients is unknown. These findings add to the growing body of work showing disparities in the treatment of LGBT persons compared to the overall population. To overcome these discrepancies, healthcare providers should adapt their practice to include this growing and underserved patient population.

Completeness, accuracy, and readability of Wikipedia as a reference for patient medication information.

PubMed

Candelario, Danielle M; Vazquez, Victoria; Jackson, William; Reilly, Timothy

This study determined the completeness, accuracy, and reading level of Wikipedia patient drug information compared with the corresponding United States product insert medication guides. From the Top 200 Drugs of 2012, the top 33 medications with medication guides were analyzed. Medication guides and Wikipedia pages were downloaded on a single date to ensure continuity of Wikipedia content. To quantify the completeness and accuracy of the Wikipedia medication information, a scoring system was adapted from previously published work and compared with the 7 core domains of medication guides. Wikipedia did not provide patient information that was as complete or accurate as the information within the medication guides: 14.73 out of 42 (SD 5.75). Wikipedia medication pages were written at a significantly higher reading level compared with medication guides (Flesch reading ease score 52.93 vs. 33.24 [P <0.001]; Flesch-Kincaid grade level 10.26 vs. 6.86 [P <0.001]). Wikipedia medication pages include incomplete and inaccurate patient information compared with the corresponding product medication guides. Wikipedia patient drug information was also written at reading levels above that of medication guides and substantially above the average United States consumer health literacy level. As the public use of Wikipedia increases, the need for educating patients about the quality of information on Wikipedia and the availability of adequate patient education resources is ever more important to minimize inaccuracies and incomplete information sharing.

Limited evidence exists on the comprehension and use of Nutrition Facts tables (NFt) among adolescents and young adults. This study provides an account of how young people engage with, understand, and apply nutrition information on the current and modified versions of the NFt to compare and choose foods. Participants aged 16-24 years (n = 26) were asked to "think aloud" while viewing either the current or 1 of 5 modified NFts and completing a behavioural task. The task included a questionnaire with 9 functional items requiring participants to define, compare, interpret, and manipulate serving size and percentage daily value (%DV) information on NFts. Semi-structured interviews were conducted to further probe thought processes and difficulties experienced in completing the task. Equal serving sizes on NFts improved ability to accurately compare nutrition information between products. Most participants could define %DV and believed it can be used to compare foods, yet some confusion persisted when interpreting %DVs and manipulating serving-size information on NFts. Where serving sizes were unequal, mathematical errors were often responsible for incorrect responses. Results reinforce the need for equal serving sizes on NFts of similar products and highlight young Canadians' confusion when using nutrition information on NFts.

Information Uncertainty to Compare Qualitative Reasoning Security Risk Assessment Results

The security risk associated with malevolent acts such as those of terrorism are often void of the historical data required for a traditional PRA. Most information available to conduct security risk assessments for these malevolent acts is obtained from subject matter experts as subjective judgements. Qualitative reasoning approaches such as approximate reasoning and evidential reasoning are useful for modeling the predicted risk from information provided by subject matter experts. Absent from these approaches is a consistent means to compare the security risk assessment results. Associated with each predicted risk reasoning result is a quantifiable amount of information uncertainty which canmore » be measured and used to compare the results. This paper explores using entropy measures to quantify the information uncertainty associated with conflict and non-specificity in the predicted reasoning results. The measured quantities of conflict and non-specificity can ultimately be used to compare qualitative reasoning results which are important in triage studies and ultimately resource allocation. Straight forward extensions of previous entropy measures are presented here to quantify the non-specificity and conflict associated with security risk assessment results obtained from qualitative reasoning models.« less

The Internet is a major source of HIV-related information and resources for persons recently diagnosed with HIV/AIDS (PRDHA). This study examined the types of HIV-related websites that appear as a result of HIV-related keyword searches and the extent to which website information targets PRDHA. The first page of HIV-related webpages from 18 keyword searches was coded. Among 137 webpages meeting inclusion criteria, 63% represented HIV-informational websites, 31% targeted HIV-positive individuals, and over half contained or provided access to HIV prevention, treatment, and transmission information. Thirty-three percent of webpages contained or provided access to PRDHA-targeted information, with a greater percentage of those webpages having mobile, non-English, and "Ask the Expert" features compared with non-PRDHA targeted webpages. Implications for PRDHA include the following: (1) they should explore HIV-related websites to gain insight into the credibility of the information contained on those sites; (2) PRDHA must be aware that HIV-related websites have the potential to elicit dated, emotionally distressing, or irrelevant information; and (3) to obtain information that relates to their demographic and situational profile, they may wish to use specific key terms (e.g., "HIV women") rather than attempting to navigate webpages that arise from general search terms (e.g., "HIV"). Recommendations for future development of online resources for PRDHA include providing HIV-relevant information in a stepwise fashion, providing demographically targeted HIV information, and greater utilization of mobile technology.

Estimating Bayesian Phylogenetic Information Content

Measuring the phylogenetic information content of data has a long history in systematics. Here we explore a Bayesian approach to information content estimation. The entropy of the posterior distribution compared with the entropy of the prior distribution provides a natural way to measure information content. If the data have no information relevant to ranking tree topologies beyond the information supplied by the prior, the posterior and prior will be identical. Information in data discourages consideration of some hypotheses allowed by the prior, resulting in a posterior distribution that is more concentrated (has lower entropy) than the prior. We focus on measuring information about tree topology using marginal posterior distributions of tree topologies. We show that both the accuracy and the computational efficiency of topological information content estimation improve with use of the conditional clade distribution, which also allows topological information content to be partitioned by clade. We explore two important applications of our method: providing a compelling definition of saturation and detecting conflict among data partitions that can negatively affect analyses of concatenated data.

An understanding of preferred sources of injury information among parents is needed to develop best practices for information dissemination. Yet, almost no research examines injury information seeking for a national sample of mothers. A cross-sectional online survey was conducted in 2013 with 1081 mothers in the United States (U.S.) with at least one child <6 years. We measured self-report health literacy with the Morris Single-Item Screener (18% low), and eHealth literacy using the eHEALS (28% low). The internet was the most preferred source for injury information (76%), followed by health providers (44%), and family/friends (35%). Most mothers selected the internet as the first choice for information about bicycle helmets (65%) and car seats (63%). For poison prevention, preferences were mixed; 48% internet compared with 41% health providers. Mothers with low health literacy were more likely to have discussed injury prevention with their doctors ( P = 0.022) and searched for injury information ( P = 0.001), but less likely to report the internet as a top source ( P < .0001). Mothers with low eHealth literacy were less likely to search for injury information ( P < 0.0001) and report the internet as a top source ( P < 0.0001), and slightly more likely to rely on health providers for information ( P = 0.028). Findings suggest the internet is a common source of injury prevention information, but health providers remain a valuable resource for mothers, especially those with lower literacy skills. Despite widespread internet use, health providers should be sure to communicate injury prevention information to mothers, especially those at risk for low health literacy and eHealth literacy.

Business continuity has expanded into a discipline that spans most functional areas of large enterprises. Both the military and financial sectors have consistently demonstrated an aptitude to expand the boundaries of continuity planning and crisis mitigation. A comparison of both enterprises is provided to see how their respective methodologies compare. Interestingly, the similarities far outweigh the differences. The paper provides commentary related to comparative insight from risk practitioners' perspectives from within the US Army, one of the largest military organisations in the world, and the Bank of Montreal, one of Canada's leading financial institutions.

2016-11-01

To assess the quality of health information available online for healthcare users on obesity in pregnancy and evaluate the role of the internet as an effective medium to advocate a healthy lifestyle in pregnancy. We used the poly-search engine Polymeta and complimented the results with Google searches (till July 2015) to identify relevant websites. All open access websites in English providing advice on the risks and management of obesity in pregnancy. Two independent reviewers assessed the quality of information provided in each of the included websites for credibility, accuracy, readability, content quality and technology. We compared websites 'quality according to their target population, health topic and source of funding'. Fifty-three websites were included. A third of websites were focused on obesity in pregnancy and two thirds targeted healthcare users. The median value for the overall credibility was 5/9, 7/12 for accuracy, 57.6/100 for readability, 45/80 for content quality and 75/100 for technology. Obesity specific websites provided lower credibility compared to general health websites (p=0.008). Websites targeting health users were easier to read (p=0.001). Non-governmental funded websites demonstrated higher content quality (p=0.005). Websites that are obesity focused, targeting health users and funded by non-governmental bodies demonstrated higher composite quality scores (p=0.048). Online information on obesity in pregnancy is varied. Governmental bodies in particular need to invest more efforts to improve the quality of online health information.

The interpretation of data from the nuclear forensic analysis of illicit nuclear material of unknown origin requires comparative data from samples of known origin. One way to provide such comparative data is to create a system of national nuclear forensics libraries, in which each participating country stores information about nuclear or other radioactive material that either resides in or was manufactured by that country. Such national libraries could provide an authoritative record of the material located in or produced by a particular country, and thus forms an essential prerequisite for a government to investigate illicit uses of nuclear or othermore » radioactive material within its borders. We describe the concept of the national nuclear forensic library, recommendations for content and structure, and suggested querying methods for utilizing the information for addressing nuclear smuggling.« less

The Joint Battlespace Infosphere (JBI) Information Management (IM) services provide information exchange and persistence capabilities that support tailored, dynamic, and timely access to required information, enabling near real-time planning, control, and execution for DoD decision making. JBI IM services will be built on a substrate of network centric core enterprise services and when transitioned, will establish an interoperable information space that aggregates, integrates, fuses, and intelligently disseminates relevant information to support effective warfighter business processes. This virtual information space provides individual users with information tailored to their specific functional responsibilities and provides a highly tailored repository of, or access to, information that is designed to support a specific Community of Interest (COI), geographic area or mission. Critical to effective operation of JBI IM services is the implementation of repositories, where data, represented as information, is represented and persisted for quick and easy retrieval. This paper will address information representation, persistence and retrieval using existing database technologies to manage structured data in Extensible Markup Language (XML) format as well as unstructured data in an IM services-oriented environment. Three basic categories of database technologies will be compared and contrasted: Relational, XML-Enabled, and Native XML. These technologies have diverse properties such as maturity, performance, query language specifications, indexing, and retrieval methods. We will describe our application of these evolving technologies within the context of a JBI Reference Implementation (RI) by providing some hopefully insightful anecdotes and lessons learned along the way. This paper will also outline future directions, promising technologies and emerging COTS products that can offer more powerful information management representations, better persistence mechanisms and improved retrieval techniques.

This study is part of a wider project aiming to correlate the chemical composition of the coffee volatile fraction to its sensory properties with the end-goal of developing an instrumental analysis approach complementary to human sensory profiling. The proposed investigation strategy compares the chemical information concerning coffee aroma and flavor obtained with HS-SPME of the ground coffee and in-solution SBSE/SPME sampling combined with GC-MS to evaluate their compatibility with the cupping evaluation for quality control purposes. Roasted coffee samples with specific sensory properties were analyzed. The chemical results obtained by the three samplings were compared through multivariate analysis, and related to the samples' sensory attributes. Despite the differences between the three sampling approaches, data processing showed that the three methods provide the same kind of chemical information useful for sample discrimination, and that they could be used interchangeably to sample the coffee aroma and flavor.

The study of arctic or subarctic indigenous skin clothing material, known for its design and ability to keep the body warm, provides information about the tanning materials and techniques. The study also provides clues about the culture that created it, since tanning processes are often specific to certain indigenous groups. Untreated skin samples and samples treated with willow (Salix sp) bark extract and cod liver oil are compared in this study using both MRI and unilateral NMR techniques. The two types of samples show different proton spatial distributions and different relaxation times, which may also provide information about the tanning technique and aging behavior.

Visual representation of statistical information improves diagnostic inferences in doctors and their patients.

Garcia-Retamero, Rocio; Hoffrage, Ulrich

Doctors and patients have difficulty inferring the predictive value of a medical test from information about the prevalence of a disease and the sensitivity and false-positive rate of the test. Previous research has established that communicating such information in a format the human mind is adapted to-namely natural frequencies-as compared to probabilities, boosts accuracy of diagnostic inferences. In a study, we investigated to what extent these inferences can be improved-beyond the effect of natural frequencies-by providing visual aids. Participants were 81 doctors and 81 patients who made diagnostic inferences about three medical tests on the basis of information about prevalence of a disease, and the sensitivity and false-positive rate of the tests. Half of the participants received the information in natural frequencies, while the other half received the information in probabilities. Half of the participants only received numerical information, while the other half additionally received a visual aid representing the numerical information. In addition, participants completed a numeracy scale. Our study showed three important findings: (1) doctors and patients made more accurate inferences when information was communicated in natural frequencies as compared to probabilities; (2) visual aids boosted accuracy even when the information was provided in natural frequencies; and (3) doctors were more accurate in their diagnostic inferences than patients, though differences in accuracy disappeared when differences in numerical skills were controlled for. Our findings have important implications for medical practice as they suggest suitable ways to communicate quantitative medical data. Copyright © 2013 Elsevier Ltd. All rights reserved.

2014-09-01

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

Strengths and weaknesses of 'real-world' studies involving non-vitamin K antagonist oral anticoagulants.

Camm, A John; Fox, Keith A A

Randomised controlled trials (RCTs) provide the reference standard for comparing the efficacy of one therapy or intervention with another. However, RCTs have restrictive inclusion and exclusion criteria; thus, they are not fully representative of an unselected real-world population. Real-world evidence (RWE) studies encompass a wide range of research methodologies and data sources and can be broadly categorised as non-interventional studies, patient registries, claims database studies, patient surveys and electronic health record studies. If appropriately designed, RWE studies include a patient population that is far more representative of unselected patient populations than those of RCTs, but they do not provide a robust basis for comparing treatment strategies. RWE studies can have very large sample sizes, can provide information on treatments in patient groups that are usually excluded from RCTs, are generally less expensive and quicker than RCTs, and can assess a broad range of outcomes. Limitations of RWE studies can include low internal validity, lack of quality control surrounding data collection and susceptibility to multiple sources of bias for comparing outcomes. RWE studies can complement the findings from RCTs by providing valuable information on treatment practices and patient characteristics among unselected patients. This information is necessary to guide treatment decisions and for reimbursement and payment decisions. RWE studies have been extensively applied in the postmarketing approval assessment of non-vitamin K antagonist oral anticoagulants since 2010. However, the benefits, costs, limitations and methodological challenges associated with the different types of RWE must be considered carefully when interpreting the findings.

The purpose of this study was to conduct a descriptive and comparative analysis of the tools used by healthcare professionals specializing in addictive disorders to promote a rapprochement of information systems. The evaluation guide used to assess the compensation needs of disabled persons treated in "Maisons Départementales des Personnes Handicapées" (centres for disabled people) organizes information in different areas, including a psychological component. The guide includes social and environmental information in the "Recueil Commun sur les Addictions et les Prises en charges" (Joint Report on Drug Addiction and Drug Treatment). While the program for the medicalization of information systems includes care data, the current information about social situations remains inadequate. The international classification of diseases provides synthetic diagnostic codes to describe substance use, etiologic factors and the somatic and psychological complications inherent to addictive disorders. The current system could be radically simplified and harmonized and would benefit from adopting a more individualized approach to non-substance behavioral addictions. The international classification of disabilities provides tools for evaluating the psychological component included in the recent definition of addictive disorders. Legal information should play an integral role in the structure of the information system and in international classifications. The prevalence of episodes of care and treatment of addictive and psychological disorders was assessed at Nice University Hospital in all disciplines. Except in addiction treatment units, very few patients were found to have a RECAP file.

Self Regulation, Cognitive Capacity and Risk Taking: Investigating Heterogeneity Among Adolescents with Callous-Unemotional Traits.

2018-06-01

The majority of prior work focuses on understanding the association between callous-unemotional (CU) traits and conduct problems, providing limited information on why some youth who score high on CU traits do not engage in conduct problem behaviors. The current study investigated heterogeneity among a sub-sample of adolescents with CU traits (N = 152; Mage = 13.09, SD = 2.76, 45.6% female) identified from a large community sample. Three groups were compared: control, callous-unemotional traits only (CU-only), and combined callous-unemotional and conduct problems (CU + CP). Participants were administered a battery of neuropsychological computerized tasks assessing risk taking, self-regulation and cognitive capacity. Results indicated that youth high on CU traits and low on CP scored higher on self-regulation and were less likely to make risky decisions compared to youth with combined CU + CP. In general, the findings provided information that heterogeneity within CU traits can be explained based on differences in neuro-cognitive functioning. In addition, the characteristics of youth high on CU traits only can provide information for interventions aiming to decrease conduct problems among youth high on these traits.

(1) To assess the diagnostic accuracy of EMG in radiculopathy. (2) To evaluate the intrarater reliability and interrater reliability of EMG in radiculopathy. (3) To assess the presence of confirmation bias in EMG. Three experienced academic electromyographers interpreted 3 compact discs with 20 EMG videos (10 normal, 10 radiculopathy) in a blinded, standardized fashion without information regarding the nature of the study. The EMGs were interpreted 3 times (discs A, B, C) 1 month apart. Clinical information was provided only with disc C. Intrarater reliability was calculated by comparing interpretations in discs A and B, interrater reliability by comparing interpretation between reviewers. Confirmation bias was estimated by the difference in correct interpretations when clinical information was provided. Sensitivity was similar to previous reports (77%, confidence interval [CI] 63%-90%); specificity was 71%, CI 56%-85%. Intrarater reliability was good (κ 0.61, 95% CI 0.41-0.81); interrater reliability was lower (κ 0.53, CI 0.35-0.71). There was no substantial confirmation bias when clinical information was provided (absolute difference in correct responses 2.2%, CI -13.3% to 17.7%); the study lacked precision to exclude moderate confirmation bias. This study supports that (1) serial EMG studies should be performed by the same electromyographer since intrarater reliability is better than interrater reliability; (2) knowledge of clinical information does not bias EMG interpretation substantially; (3) EMG has moderate diagnostic accuracy for radiculopathy with modest specificity and electromyographers should exercise caution interpreting mild abnormalities. This study provides Class III evidence that EMG has moderate diagnostic accuracy and specificity for radiculopathy. © 2015 American Academy of Neurology.

Objectives: (1) To assess the diagnostic accuracy of EMG in radiculopathy. (2) To evaluate the intrarater reliability and interrater reliability of EMG in radiculopathy. (3) To assess the presence of confirmation bias in EMG. Methods: Three experienced academic electromyographers interpreted 3 compact discs with 20 EMG videos (10 normal, 10 radiculopathy) in a blinded, standardized fashion without information regarding the nature of the study. The EMGs were interpreted 3 times (discs A, B, C) 1 month apart. Clinical information was provided only with disc C. Intrarater reliability was calculated by comparing interpretations in discs A and B, interrater reliability by comparing interpretation between reviewers. Confirmation bias was estimated by the difference in correct interpretations when clinical information was provided. Results: Sensitivity was similar to previous reports (77%, confidence interval [CI] 63%–90%); specificity was 71%, CI 56%–85%. Intrarater reliability was good (κ 0.61, 95% CI 0.41–0.81); interrater reliability was lower (κ 0.53, CI 0.35–0.71). There was no substantial confirmation bias when clinical information was provided (absolute difference in correct responses 2.2%, CI −13.3% to 17.7%); the study lacked precision to exclude moderate confirmation bias. Conclusions: This study supports that (1) serial EMG studies should be performed by the same electromyographer since intrarater reliability is better than interrater reliability; (2) knowledge of clinical information does not bias EMG interpretation substantially; (3) EMG has moderate diagnostic accuracy for radiculopathy with modest specificity and electromyographers should exercise caution interpreting mild abnormalities. Classification of evidence: This study provides Class III evidence that EMG has moderate diagnostic accuracy and specificity for radiculopathy. PMID:26701380

Information needs before hospital discharge of myocardial infarction patients: a comparative, descriptive study.

To explore the information needs of patients who have received treatment for a myocardial infarction before their discharge home from an acute hospital. WHAT IS KNOWN ABOUT THE TOPIC: Providing information for myocardial infarction patients is an important nursing function and is part of the role of health-care professionals delivering cardiac rehabilitation. It is essential to acknowledge and incorporate the self-perceived needs of patients into the information they receive. Hospital stays are becoming shorter, reducing the opportunities for nurses to provide predischarge information to patients. This highlights the challenge of adequately assessing and meeting patients' information needs. A comparative, descriptive survey. A Patient Learning Needs Scale questionnaire was completed by 20 myocardial infarction patients within 72 hours of their intended discharge. Quantitative descriptive and inferential analyses were conducted using Statistical Package for Social Sciences. Patients indicated how important it was to know about each of 40 information items before discharge from hospital. Items related to medications, complications and physical activities were rated highly. Responses to an open question revealed that driving, returning to work and sources of support were issues of concern. Non-parametric Mann-Whitney U-tests showed that retired and older patients desired more information than their employed and younger counterparts, especially concerning community support. WHAT THE STUDY ADDS TO THE TOPIC: Previous research shows little examination of age and employment status in relation to the information needs of myocardial infarction patients. This study suggests that older and retired people may want more information than younger and employed patients. Older people are under represented in postdischarge cardiac rehabilitation programmes. Since these patients may need different information when discharged from younger individuals, nurses must decide how they can best meet their needs for information and continuing support.

Conditions-Based Learning Theory as a Framework for Comparative-Effectiveness Reviews: A Worked Example.

PubMed

Rourke, Liam; Leong, Jessica; Chatterly, Patricia

2018-02-16

Phenomenon: An evidence-informed era of medical education encourages the generation and use of comparative-effectiveness reviews, yet the reviews often conclude, curiously, that all instructional approaches are equally effective. We used a conditions-based learning theory to structure a review of the comparative-effectiveness literature on electrocardiogram instruction. We searched MEDLINE, EMBASE (Ovid), ERIC (Ovid), PsycINFO (Ovid), and CINAHL (EBSCO) from inception to June 2016. We selected prospective studies that examined the effect of instructional interventions on participants' knowledge and skill with electrocardiogram interpretation. Two reviewers extracted information on the quality of the studies, the effect of instruction on the acquisition of knowledge and skill, and instructional quality. Instructional quality is an index of the extent to which instruction incorporates 4 practices of Gagne's conditions-based learning theory: presenting information, eliciting performance, providing feedback, and assessing learning. Twenty-five studies (3,286 participants) evaluating 47 instructional interventions were synthesized. The methodological quality of most studies was moderate. Instructional quality varied: All interventions presented information and assessed learning, but fewer than half elicited performances or provided feedback. Instructional interventions that incorporated all 4 components improved trainees' abilities considerably more than those that incorporated 3 or fewer; respectively, standardized mean difference (SMD) = 2.80, 95% confidence interval (CI) [2.05, 3.55], versus SMD = 1.44, 95% CI [1.18, 1.69]. Studies that compared "innovative" to "traditional" types of instruction did not yield a significant pooled effect: SMD = 0.18, 95% CI [-0.09, 0.45]. Insights: The use of a conditions-based learning theory to organize the comparative-effectiveness literature reveals differences in the instructional impact of different instructional approaches. It overturns the unlikely, but common, conclusion that all approaches are equally effective.

As healthcare moves towards technology-driven population health management, clinicians must adopt complex digital platforms to access health information and document care. This study explored information literacy, a set of skills required to effectively navigate population health information systems, among primary care providers in one Veterans' Affairs (VA) medical center. Information literacy was assessed during an 8-month randomized trial that tested a population health (panel) management intervention. Providers were asked about their use and comfort with two VA digital tools for panel management at baseline, 16 weeks, and post-intervention. An 8-item scale (range 0-40) was used to measure information literacy (Cronbach's α=0.84). Scores between study arms and provider types were compared using paired t-tests and ANOVAs. Associations between self-reported digital tool use and information literacy were measured via Pearson's correlations. Providers showed moderate levels of information literacy (M= 27.4, SD 6.5). There were no significant differences in mean information literacy between physicians (M=26.4, SD 6.7) and nurses (M=30.5, SD 5.2, p=0.57 for difference), or between intervention (M=28.4, SD 6.5) and control groups (M=25.1, SD 6.2, p=0.12 for difference). Information literacy was correlated with higher rates of self-reported information system usage (r=0.547, p=0.001). Clinicians identified data access, accuracy, and interpretability as potential information literacy barriers. While exploratory in nature, cautioning generalizability, the study suggests that measuring and improving clinicians' information literacy may play a significant role in the implementation and use of digital information tools, as these tools are rapidly being deployed to enhance communication among care teams, improve health care outcomes, and reduce overall costs.

Diagnostic sonographic and radioisotope scanning techniques have been shown to be useful in the diagnosis of obstructive uropathy. The accuracy of both methods was compared and sonography was found to provide the more accurate data (sensitivity, 90%, specificity, 98%; accuracy, 97%). Sonography provides excellent anatomic information and enables one to grade the degree of dilatation. Renal radionuclide studies were less sensitive in detecting obstruction, particularly in the presence of chronic renal disease, but offered additional information regarding relative renal blood flow, total effective renal plasma flow, and interval change in renal parenchymal function.

This cross-sectional study aimed to determine the prevalence of unmet supportive care needs among prostate cancer patients. The cross-sectional study was conducted among all prostate cancer patients at the Sarawak General Hospital. Interview was done using the Supportive Care Needs Survey-Short Form (SCNS-SF) and the Health Service Utilization Questionnaires (HSUQ). Data were analysed using Statistical Package for the Social Sciences (SPSS) 20. A total of ninety-five patients participated, with majority were aged 65 and above and of primary educational level. The two most frequently reported unmet supportive care needs were "informed about cancer which is under control or diminishing" and "informed about things you can do to help yourself to get well" under the domain Health System and Information. Respondents who were older (65 years and above) had significant lower unmet needs in psychology (P<0.01), and sexuality compared to the younger group below 65 years (P<0.01). Except for physical and daily living, respondents with primary school level had significant lower unmet needs in all domains compared to secondary school level. Respondents with known stages of cancer had higher unmet needs in all domains compared to those who did not know. Healthcare providers should provide more responsive, emotionally sensitive and client-centered care to patients with prostate cancer, particularly in the area of Health System and Information, and psychological support.

Evaluation of a Novel Conjunctive Exploratory Navigation Interface for Consumer Health Information: A Crowdsourced Comparative Study

PubMed Central

Cui, Licong; Carter, Rebecca

2014-01-01

Background Numerous consumer health information websites have been developed to provide consumers access to health information. However, lookup search is insufficient for consumers to take full advantage of these rich public information resources. Exploratory search is considered a promising complementary mechanism, but its efficacy has never before been rigorously evaluated for consumer health information retrieval interfaces. Objective This study aims to (1) introduce a novel Conjunctive Exploratory Navigation Interface (CENI) for supporting effective consumer health information retrieval and navigation, and (2) evaluate the effectiveness of CENI through a search-interface comparative evaluation using crowdsourcing with Amazon Mechanical Turk (AMT). Methods We collected over 60,000 consumer health questions from NetWellness, one of the first consumer health websites to provide high-quality health information. We designed and developed a novel conjunctive exploratory navigation interface to explore NetWellness health questions with health topics as dynamic and searchable menus. To investigate the effectiveness of CENI, we developed a second interface with keyword-based search only. A crowdsourcing comparative study was carefully designed to compare three search modes of interest: (A) the topic-navigation-based CENI, (B) the keyword-based lookup interface, and (C) either the most commonly available lookup search interface with Google, or the resident advanced search offered by NetWellness. To compare the effectiveness of the three search modes, 9 search tasks were designed with relevant health questions from NetWellness. Each task included a rating of difficulty level and questions for validating the quality of answers. Ninety anonymous and unique AMT workers were recruited as participants. Results Repeated-measures ANOVA analysis of the data showed the search modes A, B, and C had statistically significant differences among their levels of difficulty (P<.001). Wilcoxon signed-rank test (one-tailed) between A and B showed that A was significantly easier than B (P<.001). Paired t tests (one-tailed) between A and C showed A was significantly easier than C (P<.001). Participant responses on the preferred search modes showed that 47.8% (43/90) participants preferred A, 25.6% (23/90) preferred B, 24.4% (22/90) preferred C. Participant comments on the preferred search modes indicated that CENI was easy to use, provided better organization of health questions by topics, allowed users to narrow down to the most relevant contents quickly, and supported the exploratory navigation by non-experts or those unsure how to initiate their search. Conclusions We presented a novel conjunctive exploratory navigation interface for consumer health information retrieval and navigation. Crowdsourcing permitted a carefully designed comparative search-interface evaluation to be completed in a timely and cost-effective manner with a relatively large number of participants recruited anonymously. Accounting for possible biases, our study has shown for the first time with crowdsourcing that the combination of exploratory navigation and lookup search is more effective than lookup search alone.

The current growth of data and information occurs rapidly in varying amount and media. These types of development will eventually produce large number of data better known as the Big Data. Business Intelligence (BI) utilizes large number of data and information for analysis so that one can obtain important information. This type of information can be used to support decision-making process. In practice a process integrating existing data and information into data warehouse is needed. This data integration process is known as Extract, Transformation and Loading (ETL). In practice, many applications have been developed to carry out the ETL process, but selection which applications are more time, cost and power effective and efficient may become a challenge. Therefore, the objective of the study was to provide comparative analysis through comparison between the ETL process using Microsoft SQL Server Integration Service (SSIS) and one using Pentaho Data Integration (PDI).

An economic analysis of five selected LANDSAT assisted information systems in Oregon

Solomon, S.; Maher, K. M.

1979-01-01

A comparative cost analysis was performed on five LANDSAT-based information systems. In all cases, the LANDSAT system was found to have cost advantages over its alternative. The information sets generated by LANDSAT and the alternative method are not identical but are comparable in terms of satisfying the needs of the sponsor. The information obtained from the LANDSAT system in some cases is said to lack precision and detail. On the other hand, it was found to be superior in terms of providing information on areas that are inaccessible and unobtainable through conventional means. There is therefore a trade-off between precision and detail, and considerations of costs. The projects examined were concerned with locating irrigation circles in Morrow County; monitoring tansy ragwort infestation; inventoring old growth Douglas fir near Spotted Owl habitats; inventoring vegetation and resources in all state-owned lands; and determining and use for Columbia River water policies.

Learning classification with auxiliary probabilistic information

Nguyen, Quang; Valizadegan, Hamed; Hauskrecht, Milos

2012-01-01

Finding ways of incorporating auxiliary information or auxiliary data into the learning process has been the topic of active data mining and machine learning research in recent years. In this work we study and develop a new framework for classification learning problem in which, in addition to class labels, the learner is provided with an auxiliary (probabilistic) information that reflects how strong the expert feels about the class label. This approach can be extremely useful for many practical classification tasks that rely on subjective label assessment and where the cost of acquiring additional auxiliary information is negligible when compared to the cost of the example analysis and labelling. We develop classification algorithms capable of using the auxiliary information to make the learning process more efficient in terms of the sample complexity. We demonstrate the benefit of the approach on a number of synthetic and real world data sets by comparing it to the learning with class labels only. PMID:25309141

Redundant information in clinical notes within electronic health record (EHR) systems is ubiquitous and may negatively impact the use of these notes by clinicians, and, potentially, the efficiency of patient care delivery. Automated methods to identify redundant versus relevant new information may provide a valuable tool for clinicians to better synthesize patient information and navigate to clinically important details. In this study, we investigated the use of language models for identification of new information in inpatient notes, and evaluated our methods using expert-derived reference standards. The best method achieved precision of 0.743, recall of 0.832 and F1-measure of 0.784. The average proportion of redundant information was similar between inpatient and outpatient progress notes (76.6% (SD=17.3%) and 76.7% (SD=14.0%), respectively). Advanced practice providers tended to have higher rates of redundancy in their notes compared to physicians. Future investigation includes the addition of semantic components and visualization of new information.

Although mental health information on the internet is often of poor quality, relatively little is known about the quality of websites, such as Wikipedia, that involve participatory information sharing. The aim of this paper was to explore the quality of user-contributed mental health-related information on Wikipedia and compare this with centrally controlled information sources. Content on 10 mental health-related topics was extracted from 14 frequently accessed websites (including Wikipedia) providing information about depression and schizophrenia, Encyclopaedia Britannica, and a psychiatry textbook. The content was rated by experts according to the following criteria: accuracy, up-to-dateness, breadth of coverage, referencing and readability. Ratings varied significantly between resources according to topic. Across all topics, Wikipedia was the most highly rated in all domains except readability. The quality of information on depression and schizophrenia on Wikipedia is generally as good as, or better than, that provided by centrally controlled websites, Encyclopaedia Britannica and a psychiatry textbook.

Utilizing findings from the APACHE III research to develop operational information system for the ICU--the APACHE III ICU Management System.

Knaus, W. A.; Draper, E. A.; Wagner, D. P.

1991-01-01

The APACHE III data base reflects the disease, physiologic status, and outcome data from 17,400 ICU patients at 40 hospitals, 26 of which were randomly selected from representative geographic regions, bed size, and teaching status. This provides a nationally representative standard for measuring several important aspects of ICU performance. Results from the study have now been used to develop an automated information system to provide real time information about expected ICU patient outcome, length of stay, production cost, and ICU performance. The information system provides several new capabilities to ICU clinicians, clinic, and hospital administrators. Among the system's capabilities are: the ability to compare local ICU performance against predetermined criteria; the ability to forecast nursing requirements; and, the ability to make both individual and group patient outcome predictions. The system also provides improved administrative support by tracking ICU charges at the point of origin and reduces staff workload eliminating the requirement for several manually maintained logs and patient lists. APACHE III has the capability to electronically interface with and utilize data already captured in existing hospital information systems, automated laboratory information systems, and patient monitoring systems. APACHE III will also be completely integrated with several CIS vendors' products. PMID:1807779

2017-02-01

An increasing number of technologies allow providers to access the results of imaging studies. This study examined differences in access of radiology images compared with text-only reports through a health information exchange system by health care professionals. The study sample included 157,256 historical sessions from a health information exchange system that enabled 1,670 physicians and non-physicians to access text-based reports and imaging over the period 2013 to 2014. The primary outcome was an indicator of access of an imaging study instead of access of a text-only report. Multilevel mixed-effects regression models were used to estimate the association between provider and session characteristics and access of images compared with text-only reports. Compared with primary care physicians, specialists had an 18% higher probability of accessing actual images instead of text-only reports (β = 0.18; P < .001). Compared with primary care practice settings, the probability of accessing images was 4% higher for specialty care practices (P < .05) and 8% lower for emergency departments (P < .05). Radiologists, orthopedists, and neurologists accounted for 79% of all the sessions with actual images accessed. Orthopedists, radiologists, surgeons, and pulmonary disease specialists accessed imaging more often than text-based reports only. Consideration for differences in the need to access images compared with text-only reports based on the type of provider and setting of care are needed to maximize the benefits of image sharing for patient care.

Physicians' perceptions of the impact of the EHR on the collection and retrieval of psychosocial information in outpatient diabetes care.

Senteio, Charles; Veinot, Tiffany; Adler-Milstein, Julia; Richardson, Caroline

2018-05-01

Psychosocial information informs clinical decisions by providing crucial context for patients' barriers to recommended self-care; this is especially important in outpatient diabetes care because outcomes are largely dependent upon self-care behavior. Little is known about provider perceptions of use of psychosocial information. Further, while EHRs have dramatically changed how providers interact with patient health information, the EHRs' role in collection and retrieval of psychosocial information is not understood. We designed a qualitative study. We used semi-structured interviews to investigate physicians' (N = 17) perspectives on the impact of EHR for psychosocial information use for outpatient Type II diabetes care decisions. We selected the constant comparative method to analyze the data. Psychosocial information is perceived as dissimilar from other clinical information such as HbA1c and prescribed medications. Its narrative form conveys the patient's story, which elucidates barriers to following self-care recommendations. The narrative is abstract, and requires interpretation of patterns. Psychosocial information is also circumstantial; hence, the patients' context determines influence on self-care. Furthermore, EHRs can impair the collection of psychosocial information because the designs of EHR tools make it difficult to document, search for, and retrieve it. Templates do not enable users from collecting the patient's 'story', and using free text fields is time consuming. Providers therefore had low use of, and confidence in, the accuracy of psychosocial information in the EHR. Workflows and EHR tools should be re-designed to better support psychosocial information collection and retrieval. Tools should enable recording and summarization of the patient's story, and the rationale for treatment decisions. Copyright © 2018 Elsevier B.V. All rights reserved.

Fossils and other paleontological information can improve phylogenetic comparative method estimates of phenotypic evolution and generate hypotheses related to species diversification. Here, we use fossil information to calibrate ancestral reconstructions of suitable climate for Sceloporus lizards in North America. Integrating data from the fossil record, general circulation models of paleoclimate during the Miocene, climate envelope modeling, and phylogenetic comparative methods provides a geographically and temporally explicit species distribution model of Sceloporus-suitable habitat through time. We provide evidence to support the historic biogeographic hypothesis of Sceloporus diversification in warm North American deserts and suggest a relatively recent Sceloporus invasion into Mexico around 6 Ma. We use a physiological model to map extinction risk. We suggest that the number of hours of restriction to a thermal refuge limited Sceloporus from inhabiting Mexico until the climate cooled enough to provide suitable habitat at approximately 6 Ma. If the future climate returns to the hotter climates of the past, Mexico, the place of highest modern Sceloporus richness, will no longer provide suitable habitats for Sceloporus to survive and reproduce.

Programs for informal caregivers of frail elderly can be adopted by States to address some of the problems associated with an expanding and costly long-term care system. In this article, highlights are given from a 3-year study of Idaho and Arizona tax incentive programs. Characteristics of informal caregivers and elderly participants are described, and elderly participants are compared with elderly nonparticipants and with the general elderly population. Tax incentives were positively related to the level of service and financial support provided by informal caregivers. Data were inadequate to determine whether the induced informal help substituted for public expenditures.

The purpose of the analysis was to compare the clinical utility of data from traditional self-monitoring of blood glucose (SMBG) to that of continuous glucose monitoring (CGM). A clinical study of the clinical accuracy of the FreeStyle Navigator CGM System (Abbott Diabetes Care, Alameda, CA), which includes SMBG capabilities, was conducted by comparison to the YSI blood glucose analyzer (YSI Inc., Yellow Springs, OH) using 58 subjects with type 1 diabetes. The Continuous Glucose-Error Grid Analysis (CG-EGA) was used as the analytical tool. Using CG-EGA, the "clinically accurate," "benign errors," and "clinical errors" were 86.8%, 8.7%, and 4.5% for SMBG and 92.7%, 3.7%, and 3.6% for CGM, respectively. If blood glucose is viewed as a process in time, SMBG would provide accurate information about this process 86.8% of the time, whereas CGM would provide accurate information about this process 92.7% of the time (P < 0.0001). In the hypoglycemic range, however, SMBG is more accurate as the "clinically accurate," "benign errors," and "clinical errors" were 83.5%, 6.4%, and 10.1% for SMBG and 57.1%, 8.4%, and 34.5% (P < 0.0001) for CGM, respectively. While SMBG produces more accurate instantaneous glucose values than CGM, control of blood glucose involves a system in flux, and CGM provides more detailed insight into the dynamics of that system. In the normal and elevated glucose ranges, the additional information about the direction and rate of glucose change provided by the FreeStyle Navigator CGM System increases the ability to make correct clinical decisions when compared to episodic SMBG tests.

The important role of information and communication technologies and their influence on methods of storing, retrieving information in digital libraries, has not only changed the meanings behind classic library activates but has also created great changes in their services. However, it seems that not all digital libraries provide their users with similar services and only some of them are successful in fulfilling their role in digital environment. The Iranian National Medical library is among those that appear to come short compared to other digital libraries around the world. By knowing the different services provided by digital libraries worldwide, one can evaluate the services provided by Iranian National Medical library. The goal of this study is a comparison between Iranian National Medical library and digital libraries of selected countries. This is an applied study and uses descriptive - survey method. The statistical population is the digital libraries around the world which were actively providing library services between October and December 2011 and were selected by using the key word "Digital Library" in Google search engine. The data-gathering tool was direct access to the websites of these digital libraries. The statistical study is descriptive and Excel software was used for data analysis and plotting of the charts. The findings showed that among the 33 digital libraries investigated worldwide, most of them provided Browse (87.87%), Search (84.84%), and Electronic information retrieval (57.57%) services. The "Help" in public services (48/48%) and "Interlibrary Loan" in traditional services (27/27%) had the highest frequency. The Iranian National Medical library provides more digital services compared to other libraries but has less classic and public services and has less than half of possible public services. Other than Iranian National Medical library, among the 33 libraries investigated, the leaders in providing different services are Library of University of California in classic services, Count Way Library of Medicine in digital services, and Library of Finland in public services. The results of this study show that among the digital libraries investigated, most provided similar public, digital, and classic services and The Iranian National Medical library has been somewhat successful in providing these services compared to other digital libraries. One can also conclude that the difference in services is at least in part due to difference in environments, information needs, and users. Iranian National Medical Library has been somewhat successful in providing library services in digital environment and needs to identify the services which are valuable to its users by identifying the users' needs and special characteristics of its environment.

Comparing virtual consults to traditional consults using an electronic health record: an observational case–control study

PubMed Central

2012-01-01

Background Patients have typically received health care through face-to-face encounters. However, expansion of electronic communication and electronic health records (EHRs) provide alternative means for patient and physicians to interact. Electronic consultations may complement regular healthcare by providing “better, faster, cheaper” processes for diagnosing, treating, and monitoring health conditions. Virtual consultation between physicians may provide a method of streamlining care, potentially saving patients the time and expense of added visits. The purpose of this study was to compare physician usage and patient satisfaction with virtual consultations (VCs) with traditional consultations (TCs) facilitated within an EHR. Methods We conducted an observational case–control survey study within Kaiser Permanente, Colorado. A sample of patients who had VCs requested by physicians (N = 270) were matched with patients who had TCs requested by physicians (N = 270), by patient age, gender, reason for the consult, and specialty department. These patients (VC and TC), were invited to participate in a satisfaction survey. In addition, 205 primary care physicians who submitted a VC or TC were surveyed. Results During the study period, 58,146 VC or TC were requested (TC = 96.3%). Patients who completed a satisfaction survey (267 out of 540 patients, 49.4% response rate) indicated they were satisfied with their care, irrespective of the kind of consult (mean 10-point Likert score of 8.5). 88 of 205 primary care physicians surveyed (42.9%) returned at least one survey; VC and TC survey response rates and consulted departments were comparable (p = 0.13). More TCs than VCs requested transfer of patient care (p = 0.03), assistance with diagnosis (p = 0.04) or initiating treatment (p =0.04). Within 3 weeks of the consultation request, 72.1% of respondents reported receiving information from VCs, compared with 33.9% of the TCs (p < 0.001). Utility of information provided by consultants and satisfaction with consultations did not differ between VCs and TCs. Conclusions Referring physicians received information from consultants more quickly from VCs compared with TCs, but the value and application of information from both types of consultations were similar. VCs may decrease the need for face-to-face specialty encounters without a decrease in the patient’s perception of care. PMID:22769592

Lip boundary detection techniques using color and depth information

This paper presents our approach to using a stereo camera to obtain 3-D image data to be used to improve existing lip boundary detection techniques. We show that depth information as provided by our approach can be used to significantly improve boundary detection systems. Our system detects the face and mouth area in the image by using color, geometric location, and additional depth information for the face. Initially, color and depth information can be used to localize the face. Then we can determine the lip region from the intensity information and the detected eye locations. The system has successfully been used to extract approximate lip regions using RGB color information of the mouth area. Merely using color information is not robust because the quality of the results may vary depending on light conditions, background, and the human race. To overcome this problem, we used a stereo camera to obtain 3-D facial images. 3-D data constructed from the depth information along with color information can provide more accurate lip boundary detection results as compared to color only based techniques.

Informing the market: the strengths and weaknesses of information in the British National Health Service.

McKee, M; Chenet, L

Many countries are experimenting with planned (or quasi-) markets to discover if they can efficiently deliver health care in keeping with societal objectives. This paper examines the information requirements of this approach. Information is necessary in order to compare the performance of providers, to support billing, and to monitor access to care. It should be accurate, unambiguous, and resistant to manipulation. We draw on a project to find out how information on hospitalisation could be used in contracting in the British National Health Service. We conclude that the existing British system fails to provide robust measures of how many patients are treated, for what conditions, and with what treatments. We identify some promising remedies, others that are more difficult, and some which may be impossible to implement in any planned market, given the uncertainty of clinical practice.

An information measure for class discrimination. [in remote sensing of crop observation

This article describes a separability measure for class discrimination. This measure is based on the Fisher information measure for estimating the mixing proportion of two classes. The Fisher information measure not only provides a means to assess quantitatively the information content in the features for separating classes, but also gives the lower bound for the variance of any unbiased estimate of the mixing proportion based on observations of the features. Unlike most commonly used separability measures, this measure is not dependent on the form of the probability distribution of the features and does not imply a specific estimation procedure. This is important because the probability distribution function that describes the data for a given class does not have simple analytic forms, such as a Gaussian. Results of applying this measure to compare the information content provided by three Landsat-derived feature vectors for the purpose of separating small grains from other crops are presented.

A DSM-5 diagnosis of attention deficit/hyperactive disorder (ADHD) requires that symptoms be present in two settings. We wanted to see how teachers and parents compare on their assessments. We evaluated how well Child Symptom Inventory-4 (CSI-4) reports from 871 parents and 634 teachers of 10-year-old children born before the 28th week of gestation provided information about indicators of school dysfunction. Kappa values for parent and teacher agreement of any ADHD were at best fair to poor (<0.41). Nevertheless, ADHD identified by each alone provided a moderate amount of information about such indicators of school dysfunction as grade repetition. Only occasionally did agreement provide more information than provided by only one reporter. Mother's social class and intelligence level did not discriminate between parents who did and did not agree with the teacher. ADHD identified by a single observer can provide appreciable information about a range of the child's functions needed for success in school and, therefore, should not be discounted when another observer does not consider the child to have ADHD symptoms. ©2017 Foundation Acta Paediatrica.

Objective Self-reports of personality provide valid information about personality disorders (PDs). However, informant-reports provide information about PDs that self-reports alone do not provide. The current paper examines if and when one perspective is more valid than the other in identifying PDs. Method Using a representative sample of adults 55 to 65 year of age (N = 991; 45% males), we compared the validity of self- and informant- (e.g., spouse, family, or friend) reports of the FFM traits in predicting PD scores (i.e., composite of interviewer, self-, and informant-reports of PDs). Results Self-reports (particularly of neuroticism) were more valid than informant-reports for most internalizing PDs (i.e., PDs defined by high neuroticism). Informant-reports (particularly of agreeableness and conscientiousness) were more valid than self-reports for externalizing and/or antagonistic PDs (i.e., PDs defined by low agreeableness, conscientiousness). Neither report was consistently more valid for thought disorder PDs (i.e., PDs defined by low extraversion). However, informant-reports (particularly of agreeableness) were more valid than self-reports for PDs that were both internalizing and externalizing (i.e., PDs defined by high neuroticism and low agreeableness). Conclusions The intrapersonal and interpersonal manifestations of PDs differ, and these differences influence who knows more about pathology. PMID:22583054

Shipwrecks serve as artificial reefs in the deep ocean. Because of their inherent diversity compared to their surrounding environment and their random distribution, shipwrecks are ideal ecosystems to study pollution impacts and microbial distribution patterns in the deep biosphere. This study provides a comparative assessment of Deepwater Horizon spill impacts on shipwreck and local sedimentary microbiomes and the synergistic effects of contaminants on these communities and the physical structures that support them. For this study, microbiomes associated with wooden 19th century shipwrecks and World War II era steel shipwrecks in the northern Gulf of Mexico were investigated using next generation sequencing. Samples derived from in situ biofilm monitoring platforms deployed adjacent to 5 shipwrecks for 4 months, and sediment collected from distances ranging from 2-200m from each shipwreck were evaluated for shifts in microbiome structure and gene function relative to proximity to the spill, and oil spill related contaminants in the local environment. The goals of the investigation are to determine impacts to recruitment and community structure at sites located within and outside of areas impacted by the spill. Taxonomic classification of dominant and rare members of shipwreck microbiomes and metabolic information extracted from sequence data yield new understanding of microbial processes associated with site formation. The study provides information on the identity of microbial inhabitants of shipwrecks, their role in site preservation, and impacts of the Deepwater Horizon spill on the primary colonizers of artificial reefs in the deep ocean. This approach could inform about the role of microorganisms in establishment and maintenance of the artificial reef environment, while providing information about ecosystem feedbacks resulting from spills.

Previous studies show that the healthcare industry lags behind many other economic sectors in the adoption of information technology. The purpose of this study is to understand differences in structural characteristics between providers that do and that do not adopt Health Information Technology (HIT) applications. Publicly available secondary data were used from three sources: American Hospital Association (AHA) annual survey, Healthcare Information and Management Systems Society (HIMSS) analytics annual survey, and Healthcare Cost and Utilization Project (HCUP) Nationwide Inpatient Sample (NIS) databases. Fifty-two information technologies were grouped into three clusters: clinical, administrative, and strategic decision making ITs. Negative binomial regression was applied with adoption of technology as the dependent variables and eight organizational and contextual factors as the independent variables. Hospitals adopt a relatively larger proportion of administrative information technology as compared to clinical and strategic IT. Large size, urban location and HMO penetration were found to be the most influential hospital characteristics that positively affect information technology adoption. There are still considerable variations in the adoption of information technology across hospitals and in the type of technology adopted. Organizational factors appear to be more influential than market factors when it comes to information technology adoption. The future research may examine whether the Electronic Health Record (EHR) Incentive Program in 2011 would increase the information technology uses in hospitals as it provides financial incentives for HER adoptions and uses among providers.

A web-based database management system developed for collecting, managing and analysing information of diabetes patients is described here. It is a searchable, client-server, relational database application, developed on the Windows platform using Oracle, Active Server Pages (ASP), Visual Basic Script (VB Script) and Java Script. The software is menu-driven and allows authorized healthcare providers to access, enter, update and analyse patient information. Graphical representation of data can be generated by the system using bar charts and pie charts. An interactive web interface allows users to query the database and generate reports. Alpha- and beta-testing of the system was carried out and the system at present holds records of 500 diabetes patients and is found useful in diagnosis and treatment. In addition to providing patient data on a continuous basis in a simple format, the system is used in population and comparative analysis. It has proved to be of significant advantage to the healthcare provider as compared to the paper-based system.

The emergence of artemisinin-resistant Plasmodium falciparum parasites in Southeast Asia threatens global malaria control efforts. One strategy to counter this problem is a subsidy of malaria rapid diagnostic tests (RDTs) and artemisinin-based combination therapy (ACT) within the informal private sector, where the majority of malaria care in Myanmar is provided. A study in Myanmar evaluated the effectiveness of financial incentives vs information, education and counselling (IEC) in driving the proper use of subsidized malaria RDTs among informal private providers. This cost-effectiveness analysis compares intervention options. A decision tree was constructed in a spreadsheet to estimate the incremental cost-effectiveness ratios (ICERs) among four strategies: no intervention, simple subsidy, subsidy with financial incentives, and subsidy with IEC. Model inputs included programmatic costs (in dollars), malaria epidemiology and observed study outcomes. Data sources included expenditure records, study data and scientific literature. Model outcomes included the proportion of properly and improperly treated individuals with and without P. falciparum malaria, and associated disability-adjusted life years (DALYs). Results are reported as ICERs in US dollars per DALY averted. One-way sensitivity analysis assessed how outcomes depend on uncertainty in inputs. ICERs from the least to most expensive intervention are: $1,169/DALY averted for simple subsidy vs no intervention, $185/DALY averted for subsidy with financial incentives vs simple subsidy, and $200/DALY averted for a subsidy with IEC vs subsidy with financial incentives. Due to decreasing ICERs, each strategy was also compared to no intervention. The subsidy with IEC was the most favourable, costing $639/DALY averted compared with no intervention. One-way sensitivity analysis shows that ICERs are most affected by programme costs, RDT uptake, treatment-seeking behaviour, and the prevalence and virulence of non-malarial fevers. In conclusion, private provider subsidies with IEC or a combination of IEC and financial incentives may be a good investment for malaria control.

Different forms and online tools are available in different countries for spontaneous reporting, one of the most widely used methods of pharmacovigilance. Capturing sufficient information and adequate compatibility of online systems with respective reporting form is highly desirable for appropriate reporting of adverse drug reactions (ADRs). This study was aimed to compare three major online reporting systems (US, UK, and WHO) of the world and also to check their compatibility with the respective ADR reporting form. A total of 89 data elements to provide relevant information were found out from above three online reporting systems. All three online systems were compared regarding magnitude of information captured by each of them and scoring was done by providing a score of "1" to each element. Compatibility of ADR reporting forms of India (Red form), US (Form 3500), and UK (Yellow card form) was assessed by comparing the information gathered by them with that can be entered into their respective online reporting systems, namely, "VigiFlow," "US online reporting," and "Yellow card online reporting." Each unmatching item was given a score of "-1". VigiFlow scored "74" points, whereas online reporting systems of the US and UK scored "56" and "49," respectively, regarding magnitude of the information gathered by them. Compatibility score was found to be "0," "-9," and "-26" in case of ADR reporting systems of US, UK, and India, respectively. Our study reveals that "VigiFlow" is capable of capturing the maximum amount of information but "Form 3500" and "Online reporting system of US" are maximally compatible to each other among ADR reporting systems of all three countries.

A Comparison of the β-Substitution Method and a Bayesian Method for Analyzing Left-Censored Data

Classical statistical methods for analyzing exposure data with values below the detection limits are well described in the occupational hygiene literature, but an evaluation of a Bayesian approach for handling such data is currently lacking. Here, we first describe a Bayesian framework for analyzing censored data. We then present the results of a simulation study conducted to compare the β-substitution method with a Bayesian method for exposure datasets drawn from lognormal distributions and mixed lognormal distributions with varying sample sizes, geometric standard deviations (GSDs), and censoring for single and multiple limits of detection. For each set of factors, estimates for the arithmetic mean (AM), geometric mean, GSD, and the 95th percentile (X0.95) of the exposure distribution were obtained. We evaluated the performance of each method using relative bias, the root mean squared error (rMSE), and coverage (the proportion of the computed 95% uncertainty intervals containing the true value). The Bayesian method using non-informative priors and the β-substitution method were generally comparable in bias and rMSE when estimating the AM and GM. For the GSD and the 95th percentile, the Bayesian method with non-informative priors was more biased and had a higher rMSE than the β-substitution method, but use of more informative priors generally improved the Bayesian method’s performance, making both the bias and the rMSE more comparable to the β-substitution method. An advantage of the Bayesian method is that it provided estimates of uncertainty for these parameters of interest and good coverage, whereas the β-substitution method only provided estimates of uncertainty for the AM, and coverage was not as consistent. Selection of one or the other method depends on the needs of the practitioner, the availability of prior information, and the distribution characteristics of the measurement data. We suggest the use of Bayesian methods if the practitioner has the computational resources and prior information, as the method would generally provide accurate estimates and also provides the distributions of all of the parameters, which could be useful for making decisions in some applications.

The EU prescribes that food business operators must use food chain information to assist in food safety control. This study analyses usefulness of food chain information about antibiotic usage covering the 60-day period prior to delivery of pigs to slaughter in the control of antibiotic residues in pork. A dataset with 479 test results for antibiotic residues in tissue samples of finishing pigs delivered to a Dutch slaughter company was linked to information provided by pig producers about antibiotic usage in these finishing pigs. Results show that twice as many producers reported using antibiotics in the group of 82 producers with antibiotic residues (11.0%) compared to the group without antibiotic residues (5.5%) (p=0.0686). For 89% of consignments with a finishing pig with antibiotic residues, the producer reported 'did not use antibiotics'. Food chain information about antibiotic usage provided by Dutch pig producers was no guarantee for absence of antibiotic residues in delivered finishing pigs. Copyright © 2012 Elsevier B.V.

Medicare's Hospital Compare quality reports appear to have slowed price increases for two major procedures.

PubMed

Dor, Avi; Encinosa, William E; Carey, Kathleen

2015-01-01

Previous research has found that Hospital Compare, Medicare's public reporting initiative, has had little impact on patient outcomes. However, little is known about the initiative's impact on hospital prices, which may be significant because private insurers are generally well positioned to respond to quality information when negotiating prices with hospitals. We estimated difference-in-differences models of the effects of Hospital Compare quality reporting on transaction prices for two major cardiac procedures, coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI). States that had mandated their own public reporting systems before the implementation of Hospital Compare formed the control group. We found that prices for these procedures continued to increase overall after the initiation of Hospital Compare quality scores, but the rate of increase was significantly lower in states with no quality reporting metrics of their own before Hospital Compare, when compared to the control states (annual rates of increase of 4.4 percent versus 8.7 percent for PCI, and 3.9 percent versus 10.6 percent for CABG, adjusted for overall inflation). This finding implies that Hospital Compare provided leverage to purchasers in moderating price increases, while adding competitive pressures on hospitals. Providing accurate quality information on both hospitals and health plans could benefit consumers. Project HOPE—The People-to-People Health Foundation, Inc.

Choosing a Model of Maternity Care: Decision Support Needs of Australian Women.

Access to information on the features and outcomes associated with the various models of maternity care available in Australia is vital for women's informed decision-making. This study sought to identify women's preferences for information access and decision-making involvement, as well as their priority information needs, for model of care decision-making. A convenience sample of adult women of childbearing age in Queensland, Australia were recruited to complete an online survey assessing their model of care decision support needs. Knowledge on models of care and socio-demographic characteristics were also assessed. Altogether, 641 women provided usable survey data. Of these women, 26.7 percent had heard of all available models of care before starting the survey. Most women wanted access to information on models of care (90.4%) and an active role in decision-making (99.0%). Nine priority information needs were identified: cost, access to choice of mode of birth and care provider, after hours provider contact, continuity of carer in labor/birth, mobility during labor, discussion of the pros/cons of medical procedures, rates of skin-to-skin contact after birth, and availability at a preferred birth location. This information encompassed the priority needs of women across age, birth history, and insurance status subgroups. This study demonstrates Australian women's unmet needs for information that supports them to effectively compare available options for model of maternity care. Findings provide clear direction on what information should be prioritized and ideal channels for information access to support quality decision-making in practice. © 2015 Wiley Periodicals, Inc.

The research provides an understanding of pandemic information needs and informs professional development initiatives for librarians in disaster medicine. Utilizing a multisite, comparative case series design, the researchers conducted semi-structured interviews and examined supplementary materials in the form of organizational documents, correspondence, and websites to create a complete picture of each case. The rigor of the case series was ensured through data and investigator triangulation. Interview transcripts were coded using NVivo to identify common themes and points of comparison. Comparison of the four cases revealed a distinct difference between "client-initiated" and "librarian-initiated" provision of pandemic information. Librarian-initiated projects utilized social software to "push" information, whereas client-initiated projects operated within patron-determined parameters to deliver information. Health care administrators were identified as a key audience for pandemic information, and news agencies were utilized as essential information sources. Librarians' skills at evaluating available information proved crucial for selecting best-quality evidence to support administrative decision making. Qualitative analysis resulted in increased understanding of pandemic information needs and identified best practices for disseminating information during periods of high organizational stress caused by an influx of new cases of an unknown infectious disease.

2007-01-01

Background Internet mailing lists are an important and increasingly common way for cancer survivors to find information and support. Most studies of these mailing lists have investigated lists dedicated to one type of cancer, most often breast cancer. Little is known about whether the lessons learned from experiences with breast cancer lists apply to other cancers. Objectives The aim of the study was to compare the structural characteristics of 10 Internet cancer-related mailing lists and identify the processes by which cancer survivors provide support. Methods We studied a systematic 9% sample of email messages sent over five months to 10 cancer mailing lists hosted by the Association of Cancer Online Resources (ACOR). Content analyses were used to compare the structural characteristics of the lists, including participation rates and members’ identities as survivors or caregivers. We used thematic analyses to examine the types of support that list members provided through their message texts. Results Content analyses showed that characteristics of list members and subscriber participation rates varied across the lists. Thematic analyses revealed very little “off topic” discussion. Feedback from listowners indicated that they actively modeled appropriate communication on their lists and worked to keep discussions civil and focused. In all lists, members offered support much more frequently than they requested it; survivors were somewhat more likely than caregivers to offer rather than to ask for support. The most common topics in survivors’ messages were about treatment information and how to communicate with health care providers. Although expressions of emotional support were less common than informational support, they appeared in all lists. Many messages that contained narratives of illness or treatment did not specifically ask for help but provided emotional support by reassuring listmates that they were not alone in their struggles with cancer. Survivors’ explicit expressions of emotional support tended to be messages that encouraged active coping. Such messages also provided senders with opportunities to assume personally empowering “helper” roles that supported self-esteem. Conclusions Many cancer survivors use the Internet to seek informational and emotional support. Across 10 lists for different cancers, informational support was the main communication style. Our finding of an emphasis on informational support is in contrast to most prior literature, which has focused on emotional support. We found the most common expressions of support were offers of technical information and explicit advice about how to communicate with health care providers. Topics and proportions of informational and emotional support differed across the lists. Our previous surveys of ACOR subscribers showed that they join the lists primarily to seek information; this qualitative study shows that they can and do find what they seek. They also find opportunities to play rewarding roles as support givers. PMID:17513283

Effective flood risk management requires updated information to ensure that the correct decisions can be made. This can be provided by Wireless Sensor Networks (WSN) which are a low-cost means of collecting updated information about rivers. Another valuable resource is Volunteered Geographic Information (VGI) which is a comparatively new means of improving the coverage of monitored areas because it is able to supply supplementary information to the WSN and thus support decision-making in flood risk management. However, there still remains the problem of how to combine WSN data with VGI. In this paper, an attempt is made to investigate AGORA-DS, which is a Spatial Decision Support System (SDSS) that is able to make flood risk management more effective by combining these data sources, i.e. WSN with VGI. This approach is built over a conceptual model that complies with the interoperable standards laid down by the Open Geospatial Consortium (OGC) - e.g. Sensor Observation Service (SOS) and Web Feature Service (WFS) - and seeks to combine and present unified information in a web-based decision support tool. This work was deployed in a real scenario of flood risk management in the town of São Carlos in Brazil. The evidence obtained from this deployment confirmed that interoperable standards can support the integration of data from distinct data sources. In addition, they also show that VGI is able to provide information about areas of the river basin which lack data since there is no appropriate station in the area. Hence it provides a valuable support for the WSN data. It can thus be concluded that AGORA-DS is able to combine information provided by WSN and VGI, and provide useful information for supporting flood risk management.

Online maritime health information: an overview of the situation.

PubMed

Due to their working conditions, seafarers often don't benefit from the same medical coverage than the onshore population. Therefore, seafarers and their relatives often need to locate health information by themselves. While the rise of the Internet has drastically transformed the way people can gather information, the availability of specific maritime health information online still need to be evaluated scientifically. We aim here to document of the characteristic of maritime health-related online information. A web survey was performed, articulated on two complementary analyses. First, an overall analysis of websites related to maritime health compared to websites related to two other health areas relevant for the general population (dental health and otorhinolaryngology) used as control. Second, an analysis of the understandability and actionability of a series of Wikipedia articles related to pathologies relevant for seafarers using the Patient Education Materials Assessment Tool (PEMAT). Online resources associated with maritime health were sparse and difficult to locate. When compared to other medical fields, maritime health websites were extremely poor in displaying useful information for seafarers. Available online resources regarding specific diseases affecting seafarers were mainly not adapted for a general audience and scored poorly both in terms of understandability and of actionability. This study provides a general overview of the degree of adaption of online material related to maritime health to seafarers' potential needs. Considerably more efforts need to be made in order to provide controlled online materials to answer the health information needs of the seafarers and their relatives.

Internet forms an opportunity to inform, teach, and connect professionals and patients. However, much information on Internet is incomplete, inaccurate, or misleading, and not only in the medical domain. Because of the potential for damage from misleading and inaccurate health information, many organizations and individuals have published or implemented scoring tools for evaluating the appropriateness or quality of these resources. The objective of this study is to identify and summarize scoring tools that have evaluated web-sites providing reproductive health information in order to compare them and recommend an overarching evaluation tool. We searched Ovid MEDLINE(R) (1946 to July 2013) and OVID Embase (1980 to July 2013); and included English language studies that have evaluated the quality of websites providing reproductive health information. Studies only assessing the content of websites were excluded. We identified 5 scoring tools: 1-The HON (health on the net) Code of Conduct for medical and health Web sites, 2-Silberg scores, 3-Hogne Sandvik scale, 4-Jim Kapoun's Criteria for Evaluating Web Pages, and 5-The Health Information Technology Institute (HITI) criteria. We have compared these scales and identified 14 criteria: authorship, ownership, currency, objectivity/content, transparency/source, interactivity, privacy/ethics, financial disclosure, navigability/links, complementarity, advertising policy, design, quantity, and accessibility. We integrated these criteria and introduced a new tool with 10 criteria. Website evaluation tools differ in their evaluation criteria and there is a lack of consensus about which to use; therefore, an integrated easy to use set of criteria is needed.

Differing Strategies to Meet Information-Sharing Needs: Publicly Supported Community Health Information Exchanges Versus Health Systems' Enterprise Health Information Exchanges.

PubMed

Vest, Joshua R; Kash, Bita A

2016-03-01

Community health information exchanges have the characteristics of a public good, and they support population health initiatives at the state and national levels. However, current policy equally incentivizes health systems to create their own information exchanges covering more narrowly defined populations. Noninteroperable electronic health records and vendors' expensive custom interfaces are hindering health information exchanges. Moreover, vendors are imposing the costs of interoperability on health systems and community health information exchanges. Health systems are creating networks of targeted physicians and facilities by funding connections to their own enterprise health information exchanges. These private networks may change referral patterns and foster more integration with outpatient providers. The United States has invested billions of dollars to encourage the adoption of and implement the information technologies necessary for health information exchange (HIE), enabling providers to efficiently and effectively share patient information with other providers. Health care providers now have multiple options for obtaining and sharing patient information. Community HIEs facilitate information sharing for a broad group of providers within a region. Enterprise HIEs are operated by health systems and share information among affiliated hospitals and providers. We sought to identify why hospitals and health systems choose either to participate in community HIEs or to establish enterprise HIEs. We conducted semistructured interviews with 40 policymakers, community and enterprise HIE leaders, and health care executives from 19 different organizations. Our qualitative analysis used a general inductive and comparative approach to identify factors influencing participation in, and the success of, each approach to HIE. Enterprise HIEs support health systems' strategic goals through the control of an information technology network consisting of desired trading partners. Community HIEs support obtaining patient information from the broadest set of providers, but with more dispersed benefits to all participants, the community, and patients. Although not an either/or decision, community and enterprise HIEs compete for finite organizational resources like time, skilled staff, and money. Both approaches face challenges due to vendor costs and less-than-interoperable technology. Both community and enterprise HIEs support aggregating clinical data and following patients across settings. Although they can be complementary, community and enterprise HIEs nonetheless compete for providers' attention and organizational resources. Health policymakers might try to encourage the type of widespread information exchange pursued by community HIEs, but the business case for enterprise HIEs clearly is stronger. The sustainability of a community HIE, potentially a public good, may necessitate ongoing public funding and supportive regulation. © 2016 Milbank Memorial Fund.

A Group Based Key Sharing and Management Algorithm for Vehicular Ad Hoc Networks

Moharram, Mohammed Morsi; Azam, Farzana

2014-01-01

Vehicular ad hoc networks (VANETs) are one special type of ad hoc networks that involves vehicles on roads. Typically like ad hoc networks, broadcast approach is used for data dissemination. Blind broadcast to each and every node results in exchange of useless and irrelevant messages and hence creates an overhead. Unicasting is not preferred in ad-hoc networks due to the dynamic topology and the resource requirements as compared to broadcasting. Simple broadcasting techniques create several problems on privacy, disturbance, and resource utilization. In this paper, we propose media mixing algorithm to decide what information should be provided to each user and how to provide such information. Results obtained through simulation show that fewer number of keys are needed to share compared to simple broadcasting. Privacy is also enhanced through this approach. PMID:24587749

Commentary: public disclosure in the health field: is there a relevant option?

PubMed

Weil, T P

2001-01-01

Steadily increasing numbers of private, not-for-profit, and public agencies are releasing quality of care and financial information to enhance the market power of those purchasing America's health services. These sources range widely from the Health Plan Employer Data and Information Set (HEDIS) to the federal Securities and Exchange Commission (SEC). A growing interest in publicly disclosing performance information that concerns providers, as recently recommended by the Institute of Medicine (IOM) report on patient safety, until now has only achieved a modest impact. A major exception is in those metropolitan areas where acute-care facilities experience intense competition for patient admissions. Although the comparative quality and cost information currently available is for the most part in the public interest, it is concluded that, in the foreseeable future, these report cards as now structured will not result in any significant enhancement in access, improvement in quality, or reduction in cost. Options to encourage more public disclosure explored in this paper are Congress potentially passing legislation (a) to establish a Center for Patient Safety within the US Department of Health and Human Services as recommended by the recent Institute of IOM study, or (b) empowering the SEC beyond its current mandate to collect and disseminate all pertinent quality of care and cost information on every provider in the United States. The latter alternative would include user-friendly, comparative analyses to be provided on the Internet and elsewhere and would make readily available information from HEDIS, the Joint Commission on the Accreditation of Healthcare Organization (JCAHO), coronary artery bypass graft (CABG) surgery studies, cost comparisons based on Medicare cost reports and SEC filings, and other similar sources.

What's on the menu? A review of the energy and nutritional content of US chain restaurant menus.

Wu, Helen W; Sturm, Roland

2013-01-01

The present study aimed to (i) describe the availability of nutrition information in major chain restaurants, (ii) document the energy and nutrient levels of menu items, (iii) evaluate relationships with restaurant characteristics, menu labelling and trans fat laws, and nutrition information accessibility, and (iv) compare energy and nutrient levels against industry-sponsored and government-issued nutrition criteria. Descriptive statistics and multivariate regression analysis of the energy, total fat, saturated fat, trans fat, sodium, carbohydrate and protein levels of 29 531 regular and 1392 children's menu items [corrected]. Energy and nutrition information provided on restaurant websites or upon request, and secondary databases on restaurant characteristics. The top 400 US chain restaurants by sales, based on the 2009 list of the Restaurants & Institutions magazine. Complete nutrition information was reported for 245 (61 %) restaurants. Appetizers had more energy, fat and sodium than all other item types. Children's menu specialty beverages had more fat, saturated fat and carbohydrates than comparable regular menu beverages. The majority of main entrées fell below one-third of the US Department of Agriculture's estimated daily energy needs, but as few as 3 % were also within limits for sodium, fat and saturated fat. Main entrées had significantly more energy, fat and saturated fat in family-style restaurants than in fast-food restaurants. Restaurants that made nutrition information easily accessible on websites had significantly lower energy, fat and sodium contents across menu offerings than those providing information only upon request. The paper provides a comprehensive view of chain restaurant menu nutrition prior to nationwide labelling laws. It offers baseline data to evaluate how restaurants respond after laws are implemented.

"Do Users Do What They Think They Do?"- A Comparative Study of User Perceived and Actual Information Searching Behaviour in the National Electronic Library of Infection

In the last decade, the Internet has profoundly changed the delivery of healthcare. Medical websites for professionals and patients are playing an increasingly important role in providing the latest evidence-based knowledge for professionals, facilitating virtual patient support groups, and providing an invaluable information source for patients. Information seeking is the key user activity on the Internet. However, the discrepancy between what information is available and what the user is able to find has a profound effect on user satisfaction. The UK National electronic Library of Infection (NeLI, www.neli.org.uk) and its subsidiary projects provide a single-access portal for quality-appraised evidence in infectious diseases. We use this national portal, as test-bed for investigating our research questions. In this paper, we investigate actual and perceived user navigation behaviour that reveals important information about user perceptions and actions, in searching for information. Our results show: (i) all users were able to access information they were seeking; (ii) broadly, there is an agreement between "reported" behaviour (from questionnaires) and "observed" behaviour (from web logs), although some important differences were identified; (iii) both browsing and searching were equally used to answer specific questions and (iv) the preferred route for browsing for data on the NeLI website was to enter via the "Top Ten Topics" menu option. These findings provide important insights into how to improve user experience and satisfaction with health information websites.

Improving Zernike moments comparison for optimal similarity and rotation angle retrieval.

PubMed

Revaud, Jérôme; Lavoué, Guillaume; Baskurt, Atilla

2009-04-01

Zernike moments constitute a powerful shape descriptor in terms of robustness and description capability. However the classical way of comparing two Zernike descriptors only takes into account the magnitude of the moments and loses the phase information. The novelty of our approach is to take advantage of the phase information in the comparison process while still preserving the invariance to rotation. This new Zernike comparator provides a more accurate similarity measure together with the optimal rotation angle between the patterns, while keeping the same complexity as the classical approach. This angle information is particularly of interest for many applications, including 3D scene understanding through images. Experiments demonstrate that our comparator outperforms the classical one in terms of similarity measure. In particular the robustness of the retrieval against noise and geometric deformation is greatly improved. Moreover, the rotation angle estimation is also more accurate than state-of-the-art algorithms.

Accuracy and completeness of drug information in Wikipedia medication monographs.

PubMed

Reilly, Timothy; Jackson, William; Berger, Victoria; Candelario, Danielle

The primary objective of this study was to determine the accuracy and completeness of drug information on Wikipedia and Micromedex compared with U.S. Food and Drug Administration-approved U.S. product inserts. The top 10 brand and top 10 generic medications from the 2012 Institute for Health Informatics' list of top 200 drugs were selected for evaluation. Wikipedia medication information was evaluated and compared with Micromedex in 7 sections of drug information; the U.S. product inserts were used as the standard comparator. Wikipedia demonstrated significantly lower completeness and accuracy scores compared with Micromedex (mean composite scores 18.55 vs. 38.4, respectively; P <0.01). No difference was found between the mean composite scores for brand versus generic drugs in either reference (17.8 vs. 19.3, respectively [P = 0.62], for Wikipedia; 39.2 vs. 37.6, [P = 0.06] for Micromedex). Limitations to these results include the speed with which information is edited on Wikipedia, that there was no evaluation of off-label information, and the limited number of drugs that were evaluated. Wikipedia lacks the accuracy and completeness of standard clinical references and should not be a routine part of clinical decision making. More research should be conducted to evaluate the rationale for health care providers' use of Wikipedia. Copyright © 2016 American Pharmacists Association®. Published by Elsevier Inc.

2014-10-01

In this methodological study, the ultimate response of masonry pillars strengthened by externally bonded Carbon Fiber Reinforced Polymer (CFRP) was investigated. Historical bricks were derived from a XVII century rural building, whilst a high strength mortar was utilized for the joints. The conventional experimental information, concerning the overall reaction force and relative displacements provided by "point" sensors (LVDTs and clip gauge), were herein enriched with no-contact, full-field kinematic measurements provided by 2D Digital Image Correlation (2D DIC). Experimental information were critically compared with prediction provided by an advanced three-dimensional models, based on nonlinear finite elements under the simplifying assumption of perfect adhesion between the reinforcement and the support.

Farmers' climate information needs for long-term adaptive decisions: A case study of almonds in CA

Despite advances in climate modeling and projections, several sources report that current tools and models are not widely used in the agriculture sector. Farmers, depending on their local context, require information on very specific climatic metrics such as start of rains during the planting season, number of low temperature days during the growing season, etc. However, such specific climatic information is either not available, and/or is not synthesized and communicated in a manner that is accessible to these decision-makers. This research aims to bridge the gap between climate information and decision-making needs, by providing an improved understanding of what farmers' consider as relevant climate information, and how these needs compare with current modeling capabilities. Almond is a perennial crop, so any changes in climate within its 25-30 year lifetime can have an adverse impact on crop yield. This makes almond growers vulnerable to medium and long-term climate change. Hence, providing appropriate information on future climate projections can help guide their decisions on crop types & varieties, as well as management practices that are better adapted to future climatic conditions. Semi-structured exploratory interviews have been conducted with almond growers, farm advisors, and other industry stakeholders, with three goals: (1) to understand how growers have used climate information in the past; (2) to identify key climatic variables that are relevant - including appropriate temporal scales and acceptable uncertainty levels; and (3) to understand communication methods that could improve the usability of climate information for farm-level decision-making. The interviews showcased a great diversity amongst growers in terms of how they used weather/climate information. Discussions also indicated that there was a potential for climate information to impact long-term decisions, but only if it is provided within the right context, terminology, and communication channels. The findings offer valuable bottom-up insights into farmers' perspectives on relevance of climate information. These results will also be compared with current modeling capabilities in order to synthesize conclusions for improving the usability of climate science for agricultural decision-makers.

2016-01-01

OBJECTIVE The primary aim was to compare independent and joint performance of retrieving smoking status through different sources, including narrative text processed by natural language processing (NLP), patient-provided information (PPI), and diagnosis codes (ie, International Classification of Diseases, Ninth Revision [ICD-9]). We also compared the performance of retrieving smoking strength information (ie, heavy/light smoker) from narrative text and PPI. MATERIALS AND METHODS Our study leveraged an existing lung cancer cohort for smoking status, amount, and strength information, which was manually chart-reviewed. On the NLP side, smoking-related electronic medical record (EMR) data were retrieved first. A pattern-based smoking information extraction module was then implemented to extract smoking-related information. After that, heuristic rules were used to obtain smoking status-related information. Smoking information was also obtained from structured data sources based on diagnosis codes and PPI. Sensitivity, specificity, and accuracy were measured using patients with coverage (ie, the proportion of patients whose smoking status/strength can be effectively determined). RESULTS NLP alone has the best overall performance for smoking status extraction (patient coverage: 0.88; sensitivity: 0.97; specificity: 0.70; accuracy: 0.88); combining PPI with NLP further improved patient coverage to 0.96. ICD-9 does not provide additional improvement to NLP and its combination with PPI. For smoking strength, combining NLP with PPI has slight improvement over NLP alone. CONCLUSION These findings suggest that narrative text could serve as a more reliable and comprehensive source for obtaining smoking-related information than structured data sources. PPI, the readily available structured data, could be used as a complementary source for more comprehensive patient coverage. PMID:27980387

High-quality cancer information resources are available but underutilized by the public. Despite greater awareness of the National Cancer Institute's Cancer Information Service among low-income African Americans and Hispanics compared with Caucasians, actual Cancer Information Service usage is lower than expected, paralleling excess cancer-related morbidity and mortality for these subgroups. The proposed research examines how to connect the Cancer Information Service to low-income African-American and Hispanic women and their health care providers. The study will examine whether targeted physician mailing to women scheduled for colposcopy to follow up an abnormal Pap test can increase calls to the Cancer Information Service, enhance appropriate medical follow-up, and improve satisfaction with provider-patient communication. The study will be conducted in two clinics in ethnically diverse low-income communities in Chicago. During the formative phase, patients and providers will provide input regarding materials planned for use in the experimental phase of the study. The experimental phase will use a two-group prospective randomized controlled trial design. African American and Hispanic women with an abnormal Pap test will be randomized to Usual Care (routine colposcopy reminder letter) or Intervention (reminder plus provider recommendation to call the Cancer Information Service and sample questions to ask). Primary outcomes will be: 1) calls to the Cancer Information Service; 2) timely medical follow-up, operationalized by whether the patient keeps her colposcopy appointment within six months of the abnormal Pap; and 3) patient satisfaction with provider-patient communication at follow-up. The study examines the effectiveness of a feasible, sustainable, and culturally sensitive strategy to increase awareness and use of the Cancer Information Service among an underserved population. The goal of linking a public service (the Cancer Information Service) with real-life settings of practice (the clinics), and considering input from patients, providers, and Cancer Information Service staff, is to ensure that the intervention, if proven effective, can be incorporated into existing care systems and sustained. The approach to study design and planning is aimed at bridging the gap between research and practice/service. NCT00873288.

As is the case for environmental, ecological, astronomical, and other sciences, medical practice and research finds itself in a tsunami of data. This data deluge, due primarily to the introduction of digitalization in routine medical care and medical research, affords the opportunity for improved patient care and scientific discovery. Medical informatics is the subdiscipline of medicine created to make greater use of information in order to improve healthcare. The 4 areas of medical informatics research (information access, structure, analysis, and interaction) are used as a framework to discuss the overlap in information needs of comparative effectiveness research and potential contributions of medical informatics.

Hours per Patient Day: Not the Problem, Nor the Solution.

PubMed

Kirby, Karen K

2015-01-01

Hours per patient day (HPPD) is a metric that is easy to use in determining budgeted FTE and in comparing staffing across organizations. There are many considerations in determining the appropriate HPPD. The combination of automated patient acuity, staffing, and human resource systems provide a wealth of information for determining the budgeted HPPD and in making defensible requests for adjustments in HPPD. No matter how much data we have about staffing levels, nurse education and skill levels, the environment of care, or patient acuity, the real key is determining the outcomes we need to compare staffing against. We must quantify the savings associated with positive outcomes and get this information in the hands of the public so they can make informed decisions.

Engineering practice variation through provider agreement: a cluster-randomized feasibility trial.

Minimal-risk randomized trials that can be embedded in practice could facilitate learning health-care systems. A cluster-randomized design was proposed to compare treatment strategies by assigning clusters (eg, providers) to "favor" a particular drug, with providers retaining autonomy for specific patients. Patient informed consent might be waived, broadening inclusion. However, it is not known if providers will adhere to the assignment or whether institutional review boards will waive consent. We evaluated the feasibility of this trial design. Agreeable providers were randomized to "favor" either hydrochlorothiazide or chlorthalidone when starting patients on thiazide-type therapy for hypertension. The assignment applied when the provider had already decided to start a thiazide, and providers could deviate from the strategy as needed. Prescriptions were aggregated to produce a provider strategy-adherence rate. All four institutional review boards waived documentation of patient consent. Providers (n=18) followed their assigned strategy for most of their new thiazide prescriptions (n=138 patients). In the "favor hydrochlorothiazide" group, there was 99% adherence to that strategy. In the "favor chlorthalidone" group, chlorthalidone comprised 77% of new thiazide starts, up from 1% in the pre-study period. When the assigned strategy was followed, dosing in the recommended range was 48% for hydrochlorothiazide (25-50 mg/day) and 100% for chlorthalidone (12.5-25.0 mg/day). Providers were motivated to participate by a desire to contribute to a comparative effectiveness study. A study promotional mug, provider information letter, and interactions with the site investigator were identified as most helpful in reminding providers of their study drug strategy. Providers prescribed according to an assigned drug-choice strategy most of the time for the purpose of a comparative effectiveness study. This simple design could facilitate research participation and behavior change in non-research clinicians. Waiver of patient consent can broaden the representation of patients, providers, and settings.

The commercialization of human genetic information and related circumstances within Turkish law.

Today, human genetic information is used for commercial purposes as well. This means, based on the case, the direct or indirect commercialization of genetic information. In this study, this specific issue is analyzed in light of the new legal regulations as to the subject in the Turkish Law. Specifically, this study focuses on the issue of whether the commercialization of genetic information is allowed under the Turkish Law. This study also attempts to clarify the issue of whether there is any limitations for the commercialization of genetic information in the Turkish Law provided that the commercialization of genetic information is permitted. Prior to this legal analysis, the problems of the legal ownership for genetic information and of whether genetic information should be considered as an organ of human body is discussed. Accordingly, relevant Turkish laws and regulations are individually analyzed within this context. In the mean time legal regulations of some countries in this respect are taken into account with a comparative approach. In the end a general evaluation and suggestions are provided to the reader.

Use of Visual Cues by Adults With Traumatic Brain Injuries to Interpret Explicit and Inferential Information.

2016-01-01

Concomitant visual and cognitive impairments following traumatic brain injuries (TBIs) may be problematic when the visual modality serves as a primary source for receiving information. Further difficulties comprehending visual information may occur when interpretation requires processing inferential rather than explicit content. The purpose of this study was to compare the accuracy with which people with and without severe TBI interpreted information in contextually rich drawings. Fifteen adults with and 15 adults without severe TBI. Repeated-measures between-groups design. Participants were asked to match images to sentences that either conveyed explicit (ie, main action or background) or inferential (ie, physical or mental inference) information. The researchers compared accuracy between participant groups and among stimulus conditions. Participants with TBI demonstrated significantly poorer accuracy than participants without TBI extracting information from images. In addition, participants with TBI demonstrated significantly higher response accuracy when interpreting explicit rather than inferential information; however, no significant difference emerged between sentences referencing main action versus background information or sentences providing physical versus mental inference information for this participant group. Difficulties gaining information from visual environmental cues may arise for people with TBI given their difficulties interpreting inferential content presented through the visual modality.

Efforts to tackle the enormous burden of ill-health in low-income countries are hampered by weak health information infrastructures that do not support appropriate planning and resource allocation. For health information systems to function well, a reliable inventory of health service providers is critical. The spatial referencing of service providers to allow their representation in a geographic information system is vital if the full planning potential of such data is to be realized. A disparate series of contemporary lists of health service providers were used to update a public health facility database of Kenya last compiled in 2003. These new lists were derived primarily through the national distribution of antimalarial and antiretroviral commodities since 2006. A combination of methods, including global positioning systems, was used to map service providers. These spatially-referenced data were combined with high-resolution population maps to analyze disparity in geographic access to public health care. The updated 2008 database contained 5,334 public health facilities (67% ministry of health; 28% mission and nongovernmental organizations; 2% local authorities; and 3% employers and other ministries). This represented an overall increase of 1,862 facilities compared to 2003. Most of the additional facilities belonged to the ministry of health (79%) and the majority were dispensaries (91%). 93% of the health facilities were spatially referenced, 38% using global positioning systems compared to 21% in 2003. 89% of the population was within 5 km Euclidean distance to a public health facility in 2008 compared to 71% in 2003. Over 80% of the population outside 5 km of public health service providers was in the sparsely settled pastoralist areas of the country. We have shown that, with concerted effort, a relatively complete inventory of mapped health services is possible with enormous potential for improving planning. Expansion in public health care in Kenya has resulted in significant increases in geographic access although several areas of the country need further improvements. This information is key to future planning and with this paper we have released the digital spatial database in the public domain to assist the Kenyan Government and its partners in the health sector.

Provider Recommendations in the Face of Scientific Uncertainty: An Analysis of Audio-Recorded Discussions about Vitamin D.

Tarn, Derjung M; Paterniti, Debora A; Wenger, Neil S

2016-08-01

Little is known about how providers communicate recommendations when scientific uncertainty exists. To compare provider recommendations to those in the scientific literature, with a focus on whether uncertainty was communicated. Qualitative (inductive systematic content analysis) and quantitative analysis of previously collected audio-recorded provider-patient office visits. Sixty-one providers and a socio-economically diverse convenience sample of 603 of their patients from outpatient community- and academic-based primary care, integrative medicine, and complementary and alternative medicine provider offices in Southern California. Comparison of provider information-giving about vitamin D to professional guidelines and scientific information for which conflicting recommendations or insufficient scientific evidence exists; certainty with which information was conveyed. Ninety-two (15.3 %) of 603 visit discussions touched upon issues related to vitamin D testing, management and benefits. Vitamin D deficiency screening was discussed with 23 (25 %) patients, the definition of vitamin D deficiency with 21 (22.8 %), the optimal range for vitamin D levels with 26 (28.3 %), vitamin D supplementation dosing with 50 (54.3 %), and benefits of supplementation with 46 (50 %). For each of the professional guidelines/scientific information examined, providers conveyed information that deviated from professional guidelines and the existing scientific evidence. Of 166 statements made about vitamin D in this study, providers conveyed 160 (96.4 %) with certainty, without mention of any equivocal or contradictory evidence in the scientific literature. No uncertainty was mentioned when vitamin D dosing was discussed, even when recommended dosing was higher than guideline recommendations. Providers convey the vast majority of information and recommendations about vitamin D with certainty, even though the scientific literature contains inconsistent recommendations and declarations of inadequate evidence. Not communicating uncertainty blurs the contrast between evidence-based recommendations and those without evidence. Providers should explore best practices for involving patients in decision-making by acknowledging the uncertainty behind their recommendations.

Informed consent is an ethical process for ensuring patient autonomy. Multimedia presentations (MMPs) often aid the informed consent process for research studies. Thus, it follows that MMPs would improve informed consent in clinical settings. The aim of this study was to determine if an MMP for the informed consent process for ketamine sedation improves parental satisfaction and comprehension as compared with standard practice. This 2-phase study compared 2 methods of informed consent for ketamine sedation of pediatric patients. Phase 1 was a randomized, prospective study that compared the standard verbal consent to an MMP. Phase 2 implemented the MMP into daily work flow to validate the previous year's results. Parents completed a survey evaluating their satisfaction of the informed consent process and assessing their knowledge of ketamine sedation. Primary outcome measures were parental overall satisfaction with the informed consent process and knowledge of ketamine sedation. One hundred eighty-four families from a free-standing, urban, tertiary pediatric emergency department with over 85,000 annual visits were enrolled. Different demographics were not associated with a preference for the MMP or improved scores on the content quiz. Intervention families were more likely "to feel involved in the decision to use ketamine" and to understand that "they had the right to refuse the ketamine" as compared with control families. The intervention group scored significantly higher overall on the content section than the control group. Implementation and intervention families responded similarly to all survey sections. Multimedia presentation improves parental understanding of ketamine sedation, whereas parental satisfaction with the informed consent process remains unchanged. Use of MMP in the emergency department for informed consent shows potential for both patients and providers.

The regional drug information service: a factor in health care?

PubMed Central

Leach, F N

1978-01-01

Most regional health authorities throughout the United Kingdom have established drug information units to provide health service staff with a wide range of information about drugs and drug use. The units, which are staffed by drug information pharmacists, provide their service mainly by answering inquiries, although some disseminate information more positively through lectures and bulletins. An analysis of inquiries received by regional information units during 1976 showed that most were submitted by hospital doctors or pharmacists; comparatively few were received from general practitioners. Topics of inquiry included adverse effects of drugs, source of supply and identification, current treatment, dosage, route, precautions, and pharmaceutical problems such as stability or formulation of drug preparations. A more detailed analysis of the inquiries received by the North-western Regional Drug Information Service at Manchester over three years showed that the number of inquiries gradually increased and that more were received from general practitioners after a programme of lectures had been introduced to tell them about the service. The North-western service also received more requests from hospital pharmacists than other units, though many originated from clinicians. The regional drug information units consulted widely with clinical and other specialists in answering questions, but about a quarter of all inquiries were pharmaceutical, relating to stability and incompatibility. A multidisciplinary approach therefore seems necessary to provide a comprehensive and advisory drug information service. PMID:630339

Personal technology use is ubiquitous in the United States today and technology, in general, continues to change the face of health care. However, little is known about the personal technology use of military service members and the behavioral health care providers that treat them. This study reports the technology use of 1,101 active duty service members and 45 behavioral health care providers at a large military installation. Participants reported Internet usage; ownership of smartphones, tablets, and e-readers; usage of mobile applications (apps); and basic demographic information. Compared with providers, service members reported higher rates of smartphone ownership, were more likely to own Android smartphones than iPhones, and spent more time gaming. Both groups spent a comparable amount of time using social media. With the exception of gaming, however, differences between service members and providers were not statistically significant when demographics were matched and controlled. Among service members, younger respondents (18-34) were statistically more likely than older respondents (35-58) to own smartphones, spend time gaming, and engage in social media. Our findings can help inform provider's technology-based education and intervention of their patients and guide the development of new technologies to support the psychological health of service members.

Abstract This study compared the Applied Behavior Analysis (ABA) benefit provided by TRICARE as an early intervention for autism spectrum disorder with similar benefits in Medicaid and commercial health insurance plans. The sponsor, the Office of the Under Secretary of Defense for Personnel and Readiness, was particularly interested in how a proposed TRICARE reimbursement rate decrease from $125 per hour to $68 per hour for ABA services performed by a Board Certified Behavior Analyst compared with reimbursement rates (defined as third-party payment to the service provider) in Medicaid and commercial health insurance plans. Information on ABA coverage in state Medicaid programs was collected from Medicaid state waiver databases; subsequently, Medicaid provider reimbursement data were collected from state Medicaid fee schedules. Applied Behavior Analysis provider reimbursement in the commercial health insurance system was estimated using Truven Health MarketScan® data. A weighted mean U.S. reimbursement rate was calculated for several services using cross-state information on the number of children diagnosed with autism spectrum disorder. Locations of potential provider shortages were also identified. Medicaid and commercial insurance reimbursement rates varied considerably across the United States. This project concluded that the proposed $68-per-hour reimbursement rate for services provided by a board certified analyst was more than 25 percent below the U.S. mean. PMID:28845348

Confirmation Bias in Web-Based Search: A Randomized Online Study on the Effects of Expert Information and Social Tags on Information Search and Evaluation

PubMed Central

Oeberst, Aileen; Cress, Ulrike

2014-01-01

Background The public typically believes psychotherapy to be more effective than pharmacotherapy for depression treatments. This is not consistent with current scientific evidence, which shows that both types of treatment are about equally effective. Objective The study investigates whether this bias towards psychotherapy guides online information search and whether the bias can be reduced by explicitly providing expert information (in a blog entry) and by providing tag clouds that implicitly reveal experts’ evaluations. Methods A total of 174 participants completed a fully automated Web-based study after we invited them via mailing lists. First, participants read two blog posts by experts that either challenged or supported the bias towards psychotherapy. Subsequently, participants searched for information about depression treatment in an online environment that provided more experts’ blog posts about the effectiveness of treatments based on alleged research findings. These blogs were organized in a tag cloud; both psychotherapy tags and pharmacotherapy tags were popular. We measured tag and blog post selection, efficacy ratings of the presented treatments, and participants’ treatment recommendation after information search. Results Participants demonstrated a clear bias towards psychotherapy (mean 4.53, SD 1.99) compared to pharmacotherapy (mean 2.73, SD 2.41; t 173=7.67, P<.001, d=0.81) when rating treatment efficacy prior to the experiment. Accordingly, participants exhibited biased information search and evaluation. This bias was significantly reduced, however, when participants were exposed to tag clouds with challenging popular tags. Participants facing popular tags challenging their bias (n=61) showed significantly less biased tag selection (F 2,168=10.61, P<.001, partial eta squared=0.112), blog post selection (F 2,168=6.55, P=.002, partial eta squared=0.072), and treatment efficacy ratings (F 2,168=8.48, P<.001, partial eta squared=0.092), compared to bias-supporting tag clouds (n=56) and balanced tag clouds (n=57). Challenging (n=93) explicit expert information as presented in blog posts, compared to supporting expert information (n=81), decreased the bias in information search with regard to blog post selection (F 1,168=4.32, P=.04, partial eta squared=0.025). No significant effects were found for treatment recommendation (Ps>.33). Conclusions We conclude that the psychotherapy bias is most effectively attenuated—and even eliminated—when popular tags implicitly point to blog posts that challenge the widespread view. Explicit expert information (in a blog entry) was less successful in reducing biased information search and evaluation. Since tag clouds have the potential to counter biased information processing, we recommend their insertion. PMID:24670677

To encourage healthier food choices for children in fast-food restaurants, many initiatives have been proposed. This study aimed to examine the effect of disclosing nutritional information on parents' meal choices for their children at fast-food restaurants in South Korea. An online experimental survey using a menu board was conducted with 242 parents of children aged 2-12 years who dined with them at fast-food restaurants at least once a month. Participants were classified into two groups: the low-calorie group (n = 41) who chose at least one of the lowest calorie meals in each menu category, and the high-calorie group (n = 201) who did not. The attributes including perceived empowerment, use of provided nutritional information, and perceived difficulties were compared between the two groups. The low-calorie group perceived significantly higher empowerment with the nutritional information provided than did the high-calorie group (P = 0.020). Additionally, the low-calorie group was more interested in nutrition labeling (P < 0.001) and considered the nutritional value of menus when selecting restaurants for their children more than did the high-calorie group (P = 0.017). The low-calorie group used the nutritional information provided when choosing meals for their children significantly more than did the high-calorie group (P < 0.001), but the high-calorie group had greater difficulty using the nutritional information provided (P = 0.012). The results suggest that improving the empowerment of parents using nutritional information could be a strategy for promoting healthier parental food choices for their children at fast-food restaurants.

Food Labeling and Consumer Associations with Health, Safety, and Environment.

PubMed

Sax, Joanna K; Doran, Neal

2016-12-01

The food supply is complicated and consumers are increasingly calling for labeling on food to be more informative. In particular, consumers are asking for the labeling of food derived from genetically modified organisms (GMO) based on health, safety, and environmental concerns. At issue is whether the labels that are sought would accurately provide the information desired. The present study examined consumer (n = 181) perceptions of health, safety and the environment for foods labeled organic, natural, fat free or low fat, GMO, or non-GMO. Findings indicated that respondents consistently believed that foods labeled GMO are less healthy, safe and environmentally-friendly compared to all other labels (ps < .05). These results suggest that labels mean something to consumers, but that a disconnect may exist between the meaning associated with the label and the scientific consensus for GMO food. These findings may provide insight for the development of labels that provide information that consumers seek.

Comparing epidemiologically estimated treatment need with treatment provided in two dental schemes in Ireland

PubMed Central

2012-01-01

Background Valid estimation of dental treatment needed at population level is important for service planning. In many instances, planning is informed by survey data, which provide epidemiologically estimated need from the dental fieldworkers’ perspective. The aim of this paper is to determine the validity of this type of information for planning. A comparison of normative (epidemiologically estimated) need for selected treatments, as measured on a randomly-selected representative sample, is compared with treatment actually provided in the population from which the sample was drawn. Methods This paper compares dental treatment need-estimates, from a national survey, with treatment provided within two choice-of-dentist schemes: Scheme 1, a co-payment scheme for employed adults, and Scheme 2, a ‘free’ service for less-well-off adults. Epidemiologically estimated need for extractions, restorations, advanced restorations and denture treatments was recorded for a nationally representative sample in 2000/02. Treatments provided to employed and less-well-off adults were retrieved from the claims databases for both schemes. We used the chi-square test to compare proportions, and the student’s t-test to compare means between the survey and claims databases. Results Among employed adults, the proportion of 35-44-year-olds whose teeth had restorations was greater than estimated as needed in the survey (55.7% vs. 36.7%;p <0.0001). Mean number of teeth extracted was less than estimated as needed among 35-44 and 65+ year-olds. Among less-well-off adults, the proportion of 16-24-year-olds who had teeth extracted was greater than estimated as needed in the survey (27.4% vs. 7.9%;p <0.0001). Mean number of restorations provided was greater than estimated as needed in the survey for 16-24-year-olds (3.0 vs. 0.9; p <0.0001) and 35-44-year-olds (2.7 vs. 1.4;p <0.01). Conclusions Significant differences were found between epidemiologically estimated need and treatment provided for selected treatments, which may be accounted for by measurement differences. The gap between epidemiologically estimated need and treatment provided seems to be greatest for less-well-off adults. PMID:22898307

Kilpinen, R; Saunamäki, T; Jehkonen, M

2014-04-01

To provide a comprehensive review of studies on information processing speed in patients with obstructive sleep apnea syndrome (OSAS) as compared to healthy controls and normative data, and to determine whether continuous positive airway pressure (CPAP) treatment improves information processing speed. A systematic review was performed on studies drawn from Medline and PsycINFO (January 1990-December 2011) and identified from lists of references in these studies. After inclusion criteria, 159 articles were left for abstract review, and after exclusion criteria 44 articles were fully reviewed. The number of patients in the studies reviewed ranged from 10 to 157 and the study samples consisted mainly of men. Half of the studies reported that patients with OSAS showed reduced information processing speed when compared to healthy controls. Reduced information processing speed was seen more often (75%) when compared to norm-referenced data. Psychomotor speed seemed to be particularly liable to change. CPAP treatment improved processing speed, but the improvement was marginal when compared to placebo or conservative treatment. Patients with OSAS are affected by reduced information processing speed, which may persist despite CPAP treatment. Information processing is usually assessed as part of other cognitive functioning, not as a cognitive domain per se. However, it is important to take account of information processing speed when assessing other aspects of cognitive functioning. This will make it possible to determine whether cognitive decline in patients with OSAS is based on lower-level or higher-level cognitive processes or both. © 2013 John Wiley & Sons A/S.

Gamma-ray burst (GRB) afterglows have provided important clues to the nature of these massive explosive events, providing direct information on the nearby environment and indirect information on the central engine that powers the burst. We report the discovery of two bright x-ray flares in GRB afterglows, including a giant flare comparable in total energy to the burst itself, each peaking minutes after the burst. These strong, rapid x-ray flares imply that the central engines of the bursts have long periods of activity, with strong internal shocks continuing for hundreds of seconds after the gamma-ray emission has ended.

The case for comparability in financial reporting.

Government-owned organizations are accountable to citizens and their elected representatives. These organizations must provide financial information that will help in determining whether they are effectively pursuing their primary goal, which is to promote the general welfare. Regardless of the kind of service provided by a government-owned organization, the information needs of citizens and their elected representatives must be considered when developing accounting rules. If these needs are ignored or compromised in favor of the needs of other users, such as investors or creditors (the primary users of business financial reports), then financial reporting by government-owned organizations will not meet its objectives.

Family history assessment of personality disorders: I. Concordance with direct interview and between pairs of informants.

Ferro, T; Klein, D N

1997-01-01

The present study examined the concordance of the Family History Interview for Personality Disorders (FHIPD) with diagnoses based on direct interviews and between pairs of informants. Subjects were 224 probands participating in a series of studies of the familial transmission of mood and personality disorders and their first-degree relatives. Proband informants and relatives provided information about themselves on the Structured Clinical Interview for DSM-III-R (SCID), Personality Disorder Examination (PDE), and Eysenck Personality Questionnaire (EPQ). Information from informants about relatives was collected with the FHIPD. All assessments were made blindly and independently. Using Kappa, concordance between proband informants' family histories and relative direct reports on specific personality disorders was low, ranging from -.01 to .28, with a median of .10. Kappa for a diagnosis of any personality disorder was .16. When two independent informant reports were compared, Kappas for specific Axis II disorders ranged from .10 to .72, with a median of .28. Kappa for a diagnosis of any personality disorder was .36. These data suggest that subjects and informants provide different perspectives on Axis II psychopathology, and support the use of both sources of information whenever possible.

The Blue Button feature of online patient portals promotes patient engagement by allowing patients to easily download their personal health information. This study examines the adoption and use of the Blue Button feature in the Department of Veterans Affairs' (VA) personal health record portal, My HealtheVet. An online survey presented to a 4% random sample of My HealtheVet users between March and May 2012. Questions were designed to determine characteristics associated with Blue Button use, perceived value of use, and how Veterans with non-VA providers use the Blue Button to share information with their non-VA providers. Of the survey participants (N=18 398), 33% were current Blue Button users. The most highly endorsed benefit was that it helped patients understand their health history better because all the information was in one place (73%). Twenty-one percent of Blue Button users with a non-VA provider shared their VA health information, and 87% reported that the non-VA provider found the information somewhat or very helpful. Veterans' self-rated computer ability was the strongest factor contributing to both Blue Button use and to sharing information with non-VA providers. When comparing Blue Button users and non-users, barriers to adoption were low awareness of the feature and difficulty using the Blue Button. This study contributes to the understanding of early Blue Button adoption and use of this feature for patient-initiated sharing of health information. Educational efforts are needed to raise awareness of the Blue Button and to address usability issues that hinder adoption. Published by the BMJ Publishing Group Limited.

This article describes website information seeking strategies used by users who are blind and compares those with sighted users. It outlines how assistive technologies and website design can aid users who are blind while information seeking. People who are blind and sighted are tested using an assessment tool and performing several tasks on websites. The times and keystrokes are recorded for all tasks as well as commands used and spatial questioning. Participants who are blind used keyword-based search strategies as their primary tool to seek information. Sighted users also used keyword search techniques if they were unable to find the information using a visual scan of the home page of a website. A proposed model based on the present study for information seeking is described. Keywords are important in the strategies used by both groups of participants and providing these common and consistent keywords in locations that are accessible to the users may be useful for efficient information searching. The observations suggest that there may be a difference in how users search a website that is familiar compared to one that is unfamiliar. © 2011 Informa UK, Ltd.

WEBGIS based CropWatch online agriculture monitoring system

2015-12-01

CropWatch, which was developed by the Institute of Remote Sensing and Digital Earth (RADI), Chinese Academy of Sciences (CAS), has achieved breakthrough results in the integration of methods, independence of the assessments and support to emergency response by periodically releasing global agricultural information. Taking advantages of the multi-source remote sensing data and the openness of the data sharing policies, CropWatch group reported their monitoring results by publishing four bulletins one year. In order to better analysis and generate the bulletin and provide an alternative way to access agricultural monitoring indicators and results in CropWatch, The CropWatch online system based on the WEBGIS techniques has been developed. Figure 1 shows the CropWatch online system structure and the system UI in Clustering mode. Data visualization is sorted into three different modes: Vector mode, Raster mode and Clustering mode. Vector mode provides the statistic value for all the indicators over each monitoring units which allows users to compare current situation with historical values (average, maximum, etc.). Users can compare the profiles of each indicator over the current growing season with the historical data in a chart by selecting the region of interest (ROI). Raster mode provides pixel based anomaly of CropWatch indicators globally. In this mode, users are able to zoom in to the regions where the notable anomaly was identified from statistic values in vector mode. Data from remote sensing image series at high temporal and low spatial resolution provide key information in agriculture monitoring. Clustering mode provides integrated information on different classes in maps, the corresponding profiles for each class and the percentage of area of each class to the total area of all classes. The time series data is categorized into limited types by the ISODATA algorithm. For each clustering type, pixels on the map, profiles, and percentage legend are all linked together. All the three visualization methods are applied to four scales including 65 monitoring and reporting units (MRUs), 7 major production zones (MPZs), 173 countries and sub-countries for 9 large countries. Agro-Climatic information, Agronomic information and indicators related with crop area, crop yield and crop production are provided.

To design and implement a course in Companion Animal Comparative Counseling that would expose students (N=38) to essential elements of veterinary therapeutics and provide them with the opportunity to apply their knowledge by writing and posting client information sheets (CIS) on an open web site. The elective course was limited to companion animals. Nine different topics were covered over the semester. Class sessions included a didactic component, trivia questions, and field trips. There were 4 major graded assessments: an examination on foundation knowledge, followed by two comparative counseling assessments and evaluation of group-composed CIS. Attendance and participation were also considered. The class learned comparative disease states, how to counsel on common pet prescriptions, where to access informatics about specific veterinary drugs, and how to create their own CIS. As pharmacists, these students may have improved their training in veterinary comparative pharmacy.

Objective. To design and implement a course in Companion Animal Comparative Counseling that would expose students (N=38) to essential elements of veterinary therapeutics and provide them with the opportunity to apply their knowledge by writing and posting client information sheets (CIS) on an open web site. Design. The elective course was limited to companion animals. Nine different topics were covered over the semester. Class sessions included a didactic component, trivia questions, and field trips. There were 4 major graded assessments: an examination on foundation knowledge, followed by two comparative counseling assessments and evaluation of group-composed CIS. Attendance and participation were also considered. Assessment. The class learned comparative disease states, how to counsel on common pet prescriptions, where to access informatics about specific veterinary drugs, and how to create their own CIS. Conclusion. As pharmacists, these students may have improved their training in veterinary comparative pharmacy. PMID:26941441

Pharmacogenomic variant information is well known for major human populations; however, this information is less commonly studied in minorities. In the present study, we genotyped 85 very important pharmacogenetic (VIP) variants (selected from the PharmGKB database) in the Kyrgyz population and compared our data with other four major human populations including Han Chinese in Beijing, China (CHB), the Japanese in Tokyo, Japan (JPT), a northern and western Europe population (CEU), and the Yoruba in Ibadan, Nigeria (YRI). There were 13, 12 and 16 of the selected VIP variant genotype frequencies in the Kyrgyz which differed from those of the CHB, JPT and CEU, respectively (p<0.005). In the YRI, there were 32 different variants, compared to the Kyrgyz (p<0.005). Genotype frequencies of ADH1B, AHR, CYP3A5, PTGS2, VDR, and VKORC1 in the Kyrgyz differed widely from those in the four populations. Haplotype analyses also showed differences among the Kyrgyz and the other four populations. Our results complement the information provided by the database of pharmacogenomics on Kyrgyz. We provide a theoretical basis for safer drug administration and individualized treatment plans for the Kyrgyz. We also provide a template for the study of pharmacogenomics in various ethnic minority groups in China. © 2013 Elsevier B.V. All rights reserved.

The absorption of visible light by human skin is governed by a number of natural chromophores: Eumelanin, pheomelanin, oxyhemoglobin, and deoxyhemoglobin are the major absorbers in the visible range in cutaneous tissue. Label-free quantification of these tissue chromophores is an important step of optoacoustic (photoacoustic) imaging towards clinical application, since it provides relevant information in diseases. In tumor cells, for instance, there are metabolic changes (Warburg effect) compared to healthy cells, leading to changes in oxygenation in the environment of tumors. In malignant melanoma changes in the absorption spectrum have been observed compared to the spectrum of nonmalignant nevi. So far, optoacoustic imaging has been applied to human skin mostly in single-wavelength mode, providing anatomical information but no functional information. In this work, we excited the tissue by a tunable laser source in the spectral range from 413-680 nm with a repetition rate of 50 Hz. The laser was operated in wavelengthsweep mode emitting consecutive pulses at various wavelengths that allowed for automatic co-registration of the multispectral datasets. The multispectral raster-scan optoacoustic mesoscopy (MSOM) system provides a lateral resolution of <60 μm independent of wavelength. Based on the known absorption spectra of melanin, oxyhemoglobin, and deoxyhemoglobin, three-dimensional absorption maps of all three absorbers were calculated from the multispectral dataset.

Many studies examining the food retail environment rely on geographic information system (GIS) databases for location information. The purpose of this study was to validate information provided by two GIS databases, comparing the positional accuracy of food service places within a 1 km circular buffer surrounding 34 schools in Ontario, Canada. A commercial database (InfoCanada) and an online database (Yellow Pages) provided the addresses of food service places. Actual locations were measured using a global positioning system (GPS) device. The InfoCanada and Yellow Pages GIS databases provided the locations for 973 and 675 food service places, respectively. Overall, 749 (77.1%) and 595 (88.2%) of these were located in the field. The online database had a higher proportion of food service places found in the field. The GIS locations of 25% of the food service places were located within approximately 15 m of their actual location, 50% were within 25 m, and 75% were within 50 m. This validation study provided a detailed assessment of errors in the measurement of the location of food service places in the two databases. The location information was more accurate for the online database, however, when matching criteria were more conservative, there were no observed differences in error between the databases.

To assess the readability of the web-based patient education material provided by the European Association of Urology. English patient education materials (PEM) as available in May 2017 were obtained from the EAU website. Each topic was analyzed separately using six well-established readability assessment tools, including Flesch-Kincaid Grade Level (FKGL), SMOG Grade Level (SMOG), Coleman-Liau Index (CLI), Gunning Fog Index (GFI), Flesch Reading Ease Formula (FRE) and Fry Readability Graph (FRG). A total of 17 main topics were identified of which separate basic and in-depth information is provided for 14 topics. Calculation of grade levels (FKGL, SMOG, CLI, GFI) showed readability scores of 7th-13th grade for basic information, 8th-15th grade for in-depth information and 7th-15th grade for single PEM. Median FRE score was 54 points (range 45-65) for basic information and 56 points (41-64) for in-depth information. The FRG as a graphical assessment revealed only 13 valid results with an approximate 8th-17th grade level. The EAU provides carefully worked out PEM for 17 urological topics. Although improved readability compared to similar analyses was found, a simplification of certain chapters might be helpful to facilitate better patient understanding.

Reptilian spermatogenesis

PubMed Central

2011-01-01

Until recently, the histology and ultrastructural events of spermatogenesis in reptiles were relatively unknown. Most of the available morphological information focuses on specific stages of spermatogenesis, spermiogenesis, and/or of the mature spermatozoa. No study to date has provided complete ultrastructural information on the early events of spermatogenesis, proliferation and meiosis in class Reptilia. Furthermore, no comprehensive data set exists that describes the ultrastructure of the entire ontogenic progression of germ cells through the phases of reptilian spermatogenesis (mitosis, meiosis and spermiogenesis). The purpose of this review is to provide an ultrastructural and histological atlas of spermatogenesis in reptiles. The morphological details provided here are the first of their kind and can hopefully provide histological information on spermatogenesis that can be compared to that already known for anamniotes (fish and amphibians), birds and mammals. The data supplied in this review will provide a basic model that can be utilized for the study of sperm development in other reptiles. The use of such an atlas will hopefully stimulate more interest in collecting histological and ultrastructural data sets on spermatogenesis that may play important roles in future nontraditional phylogenetic analyses and histopathological studies in reptiles.

Modern medical information retrieval systems are paramount to manage the insurmountable quantities of clinical data. These systems empower health care experts in the diagnosis of patients and play an important role in the clinical decision process. However, the ever-growing heterogeneous information generated in medical environments poses several challenges for retrieval systems. We propose a medical information retrieval system with support for multimodal medical case-based retrieval. The system supports medical information discovery by providing multimodal search, through a novel data fusion algorithm, and term suggestions from a medical thesaurus.

Programs for informal caregivers of frail elderly can be adopted by States to address some of the problems associated with an expanding and costly long-term care system. In this article, highlights are given from a 3-year study of Idaho and Arizona tax incentive programs. Characteristics of informal caregivers and elderly participants are described, and elderly participants are compared with elderly nonparticipants and with the general elderly population. Tax incentives were positively related to the level of service and financial support provided by informal caregivers. Data were inadequate to determine whether the induced informal help substituted for public expenditures. PMID:10312965

An atlas of thermal data for biomass and other fuels

Gaur, S.; Reed, T.B.

1995-06-01

Biomass is recognized as a major source of renewable energy. In order to convert biomass energy to more useful forms, it is necessary to have accurate scientific data on the thermal properties of biomass. This Atlas has been written to supply a uniform source of that information. In the last few decades Thermal analysis (TA) tools such as thermogravimetry, differential thermal analysis, thermo mechanical analysis, etc. have become more important. The data obtained from these techniques can provide useful information in terms of reaction mechanism, kinetic parameters, thermal stability, phase transformation, heat of reaction, etc. for gas-solid and gas-liquid systems.more » Unfortunately, there are no ASTM standards set for the collection of these types of data using TA techniques and therefore, different investigators use different conditions which suit their requirements for measuring this thermal data. As a result, the information obtained from different laboratories is not comparable. This Atlas provides the ability to compare new laboratory results with a wide variety of related data available in the literature and helps ensure consistency in using these data.« less

Towards a Global Service Registry for the World-Wide LHC Computing Grid

NASA Astrophysics Data System (ADS)

Field, Laurence; Alandes Pradillo, Maria; Di Girolamo, Alessandro

2014-06-01

The World-Wide LHC Computing Grid encompasses a set of heterogeneous information systems; from central portals such as the Open Science Grid's Information Management System and the Grid Operations Centre Database, to the WLCG information system, where the information sources are the Grid services themselves. Providing a consistent view of the information, which involves synchronising all these informations systems, is a challenging activity that has lead the LHC virtual organisations to create their own configuration databases. This experience, whereby each virtual organisation's configuration database interfaces with multiple information systems, has resulted in the duplication of effort, especially relating to the use of manual checks for the handling of inconsistencies. The Global Service Registry aims to address this issue by providing a centralised service that aggregates information from multiple information systems. It shows both information on registered resources (i.e. what should be there) and available resources (i.e. what is there). The main purpose is to simplify the synchronisation of the virtual organisation's own configuration databases, which are used for job submission and data management, through the provision of a single interface for obtaining all the information. By centralising the information, automated consistency and validation checks can be performed to improve the overall quality of information provided. Although internally the GLUE 2.0 information model is used for the purpose of integration, the Global Service Registry in not dependent on any particular information model for ingestion or dissemination. The intention is to allow the virtual organisation's configuration databases to be decoupled from the underlying information systems in a transparent way and hence simplify any possible future migration due to the evolution of those systems. This paper presents the Global Service Registry architecture, its advantages compared to the current situation and how it can support the evolution of information systems.

We analyzed the data of a nationwide opinion survey reported in a previous study and clarified the importance of socioeconomic status and individual belief on people's opinion regarding the pros and cons of gestational surrogacy. In this study, we analyzed the data of this nationwide opinion survey to identify the effect of providing information about assisted reproductive technology (ART) on the people's attitude towards not only gestational surrogacy but also other ART procedures. This was a cross-sectional study. A nationwide opinion survey on ART was conducted in 2003. The participants included 3647 people (1564 people received only the questionnaire and 2083 people received the questionnaire and a brochure containing information about ART). Multivariate-adjusted odds ratio and 95% confidence interval were obtained using logistic regression models for understanding the manner in which the knowledge about ART affects the attitude of the general population towards ART, which uses donor gametes and surrogacy. With regard to gestational surrogacy, men in the brochure group could not clearly express their opinions when compared with those in the no-brochure group (odds ratio (OR): 0.69; 95% confidence interval (CI): 0.53-0.89). In contrast, with regard to donor insemination, women in the brochure group could clearly express their opinions when compared with those in the no-brochure group (OR, 1.24; CI, 1.02-1.52). Information about ART, especially in men, promoted disapproval of partial surrogacy (OR, 0.59; CI, 0.44-0.78) and gestational surrogacy (OR, 0.64; CI, 0.48-0.86). On the other hand, for other ART procedures, we found no significant association between receiving information via the brochure and people's attitude towards the technology. There were gender differences in attitude toward surrogacy that was affected by providing information about ART. Moreover, determining community attitudes, we observed that a good understanding of the information provided facilitates the expression of a clear opinion, thereby assisting respondents in deciding whether or not they approve of a certain technology.

Patient choice, Internet based information sources, and perceptions of health care: Evidence from Sweden using survey data from 2010 and 2013.

Several countries have increased patients' abilities to choose their health care providers, frequently under the assumption that patients are themselves the best agents to make such decisions. In parallel, national and regional health authorities have enhanced access to Internet based information sources (IBIS) to assist patients in making an informed choice. Relatively little, however, is known about the effect that the use of such sources has on key outcomes, including patients' perceptions of care. The aim of this study is to analyze the role of the Internet for patients' confidence in the provider and perceived access to care in the context of choice based reforms in Sweden. The study uses a regional, population health survey from the southern part of Sweden. Non-parametric chi-square tests are used to assess the nature of Internet users, including their gender, age and socioeconomic status. Logistic regression models are specified to analyze the role of IBIS on patient perceptions of care while controlling for other factors. Actual use of Internet based information sources for health care was relatively low in 2010 and only somewhat higher in 2013. The characteristics of IBIS users varied significantly across different population groups, such that they were younger, more educated, female, and also considered themselves to be in better health compared with those who reported not using this source of health care information. Finally, the average IBIS user was less likely to report having a high level of satisfaction with respect to their primary care use; OR 0.69 [95 % CI: 0.54-0,87] and OR 0.52 [95 % CI: 0,41-0,66], for confidence in provider and perceived access to care, respectively, in 2013. Despite health agencies' attempts to make information on health care providers available on the Internet, this source of health care information is not used to any large extent in the current sample. The fact that some people use this source of information more compared with others suggests the need to consider alternative ways of informing the general public about choice options. The use of Internet based sources may also be linked with the experience of actually using health services, which suggests a need to further analyze this complex consumer behavior process.

The provision of safely managed sanitation in informal settlements is a challenge, especially in schools that require durable, clean, sex-segregated facilities for a large number of children. In informal settlements in Nairobi, school sanitation facilities demand considerable capital costs, yet are prone to breakage and often unhygienic. The private sector may be able to provide quality facilities and services to schools at lower costs as an alternative to the sanitation that is traditionally provided by the government. We conducted a randomized trial comparing private sector service delivery (PSSD) of urine-diverting dry latrines with routine waste collection and maintenance and government standard delivery (GSD) of cistern-flush toilets or ventilated improved pit latrines. The primary outcomes were facility maintenance, use, exposure to fecal contamination, and cost. Schools were followed for one school year. There were few differences in maintenance and pathogen exposure between PSSD and GSD toilets. Use of the PSSD toilets was 128% higher than GSD toilets, as measured with electronic motion detectors. The initial cost of private sector service delivery was USD 2053 (KES 210,000) per school, which was lower than the average cost of rehabilitating the government standard flush-type toilets (USD 9306 (KES 922,638)) and constructing new facilities (USD 114,889 (KES 1,169,668)). The private sector delivery of dry sanitation provided a feasible alternative to the delivery of sewage sanitation in Nairobi informal settlements and might elsewhere in sub-Saharan Africa.

Observational pharmacoepidemiological studies can provide valuable information on the effectiveness or safety of interventions in the real world, but one major challenge is the existence of unmeasured confounder(s). While many analytical methods have been developed for dealing with this challenge, they appear under-utilized, perhaps due to the complexity and varied requirements for implementation. Thus, there is an unmet need to improve understanding the appropriate course of action to address unmeasured confounding under a variety of research scenarios. We implemented a stepwise search strategy to find articles discussing the assessment of unmeasured confounding in electronic literature databases. Identified publications were reviewed and characterized by the applicable research settings and information requirements required for implementing each method. We further used this information to develop a best practice recommendation to help guide the selection of appropriate analytical methods for assessing the potential impact of unmeasured confounding. Over 100 papers were reviewed, and 15 methods were identified. We used a flowchart to illustrate the best practice recommendation which was driven by 2 critical components: (1) availability of information on the unmeasured confounders; and (2) goals of the unmeasured confounding assessment. Key factors for implementation of each method were summarized in a checklist to provide further assistance to researchers for implementing these methods. When assessing comparative effectiveness or safety in observational research, the impact of unmeasured confounding should not be ignored. Instead, we suggest quantitatively evaluating the impact of unmeasured confounding and provided a best practice recommendation for selecting appropriate analytical methods.

2014-01-01

To address the need for greater evidence-based evaluation of Health Information Technology (HIT) systems we introduce a method of usability testing termed tree testing. In a tree test, participants are presented with an abstract hierarchical tree of the system taxonomy and asked to navigate through the tree in completing representative tasks. We apply tree testing to a commercially available health application, demonstrating a use case and providing a comparison with more traditional in-person usability testing methods. Online tree tests (N=54) and in-person usability tests (N=15) were conducted from August to September 2013. Tree testing provided a method to quantitatively evaluate the information structure of a system using various navigational metrics including completion time, task accuracy, and path length. The results of the analyses compared favorably to the results seen from the traditional usability test. Tree testing provides a flexible, evidence-based approach for researchers to evaluate the information structure of HITs. In addition, remote tree testing provides a quick, flexible, and high volume method of acquiring feedback in a structured format that allows for quantitative comparisons. With the diverse nature and often large quantities of health information available, addressing issues of terminology and concept classifications during the early development process of a health information system will improve navigation through the system and save future resources. Tree testing is a usability method that can be used to quickly and easily assess information hierarchy of health information systems. PMID:24582924

The purpose of this study was to identify the most adequate strategy for group comparison of longitudinal patient-reported outcomes in the presence of possibly informative intermittent missing data. Models coming from classical test theory (CTT) and item response theory (IRT) were compared. Two groups of patients' responses to dichotomous items with three times of assessment were simulated. Different cases were considered: presence or absence of a group effect and/or a time effect, a total of 100 or 200 patients, 4 or 7 items and two different values for the correlation coefficient of the latent trait between two consecutive times (0.4 or 0.9). Cases including informative and non-informative intermittent missing data were compared at different rates (15, 30 %). These simulated data were analyzed with CTT using score and mixed model (SM) and with IRT using longitudinal Rasch mixed model (LRM). The type I error, the power and the bias of the group effect estimations were compared between the two methods. This study showed that LRM performs better than SM. When the rate of missing data rose to 30 %, estimations were biased with SM mainly for informative missing data. Otherwise, LRM and SM methods were comparable concerning biases. However, regardless of the rate of intermittent missing data, power of LRM was higher compared to power of SM. In conclusion, LRM should be favored when the rate of missing data is higher than 15 %. For other cases, SM and LRM provide similar results.

Enhanced Information Retrieval Using AJAX

Information Retrieval deals with the representation, storage, organization of, and access to information items. The representation and organization of information items should provide the user with easy access to the information with the rapid development of Internet, large amounts of digitally stored information is readily available on the World Wide Web. This information is so huge that it becomes increasingly difficult and time consuming for the users to find the information relevant to their needs. The explosive growth of information on the Internet has greatly increased the need for information retrieval systems. However, most of the search engines are using conventional information retrieval systems. An information system needs to implement sophisticated pattern matching tools to determine contents at a faster rate. AJAX has recently emerged as the new tool such the of information retrieval process of information retrieval can become fast and information reaches the use at a faster pace as compared to conventional retrieval systems.

Hospitals are increasingly compared based on clinical outcomes adjusted for severity of illness. Multiple methods exist to adjust for differences between patients. The challenge for consumers of this information, both the public and healthcare providers, is interpreting differences in risk adjustment models particularly when models differ in their use of administrative and physiologic data. We set to examine how administrative and physiologic models compare to each when applied to critically ill patients. We prospectively abstracted variables for a physiologic and administrative model of mortality from two intensive care units in the United States. Predicted mortality was compared through the Pearsons Product coefficient and Bland-Altman analysis. A subgroup of patients admitted directly from the emergency department was analyzed to remove potential confounding changes in condition prior to ICU admission. We included 556 patients from two academic medical centers in this analysis. The administrative model and physiologic models predicted mortalities for the combined cohort were 15.3% (95% CI 13.7%, 16.8%) and 24.6% (95% CI 22.7%, 26.5%) (t-test p-value<0.001). The r(2) for these models was 0.297. The Bland-Atlman plot suggests that at low predicted mortality there was good agreement; however, as mortality increased the models diverged. Similar results were found when analyzing a subgroup of patients admitted directly from the emergency department. When comparing the two hospitals, there was a statistical difference when using the administrative model but not the physiologic model. Unexplained mortality, defined as those patients who died who had a predicted mortality less than 10%, was a rare event by either model. In conclusion, while it has been shown that administrative models provide estimates of mortality that are similar to physiologic models in non-critically ill patients with pneumonia, our results suggest this finding can not be applied globally to patients admitted to intensive care units. As patients and providers increasingly use publicly reported information in making health care decisions and referrals, it is critical that the provided information be understood. Our results suggest that severity of illness may influence the mortality index in administrative models. We suggest that when interpreting "report cards" or metrics, health care providers determine how the risk adjustment was made and compares to other risk adjustment models.

End-to-end imaging information rate advantages of various alternative communication systems

NASA Technical Reports Server (NTRS)

Rice, R. F.

1982-01-01

The efficiency of various deep space communication systems which are required to transmit both imaging and a typically error sensitive class of data called general science and engineering (gse) are compared. The approach jointly treats the imaging and gse transmission problems, allowing comparisons of systems which include various channel coding and data compression alternatives. Actual system comparisons include an advanced imaging communication system (AICS) which exhibits the rather significant advantages of sophisticated data compression coupled with powerful yet practical channel coding. For example, under certain conditions the improved AICS efficiency could provide as much as two orders of magnitude increase in imaging information rate compared to a single channel uncoded, uncompressed system while maintaining the same gse data rate in both systems. Additional details describing AICS compression and coding concepts as well as efforts to apply them are provided in support of the system analysis.

The Medical Student Performance Evaluation (MSPE) appendices provide a program director with comparative performance for a student's academic and professional attributes, but they are frequently absent or incomplete. We reviewed MSPEs from applicants to our emergency medicine residency program from 134 of 136 (99%) U.S. allopathic medical schools, over two application cycles (2012-13, 2014-15). We determined the degree of compliance with each of the five recommended MSPE appendices. Only three (2%) medical schools were compliant with all five appendices. The medical school information page (MSIP, appendix E) was present most commonly (85%), followed by comparative clerkship performance (appendix B, 82%), overall performance (appendix D, 59%), preclinical performance (appendix A, 57%), and professional attributes (appendix C, 18%). Few schools (7%) provided student-specific, comparative professionalism assessments. Medical schools inconsistently provide graphic, comparative data for their students in the MSPE. Although program directors (PD) value evidence of an applicant's professionalism when selecting residents, medical schools rarely provide such useful, comparative professionalism data in their MSPEs. As PDs seek to evaluate applicants based on academic performance and professionalism, rather than standardized testing alone, medical schools must make MSPEs more consistent, objective, and comparative.

The health care industry is rich in data and information. Web technologies, such as search engines and social media, have provided an opportunity for the management of user generated data in real time in the form of infodemiology studies. The aim of this study was to investigate infodemiology studies conducted during 2002-2016, and compare them based on developed, developing and in transition countries. This scoping review was conducted in 2017 with the help of the PRISMA guidelines. PubMed, Scopus, Science Direct, Web of Knowledge, Google Scholar, Wiley and Springer databases were searched between the years 2002 and 2016. Finally, 56 articles were included in the review and analysed. The initial infodemiology studies pertain to the quality assessment of the hospital's websites. Most of the studies were on developed countries, based on flu, and published in the Journal of Medical Internet Research. The infodemiology approach provides unmatched opportunities for the management of health data and information generated by the users. Using this potential will provide unique opportunities for the health information need assessment in real time by health librarians and thereby provide evidence based health information to the people. © 2018 Health Libraries Group.

Although providing necessary information to patients with Crohn disease (CD) can influence their quality of life, there has been no study regarding the information provided by healthcare providers to CD patients. The aim of our study was to describe the contents of brochures given to CD patients in Japanese hospitals. These brochures were compared with ones used in the United States, Canada, and the United Kingdom. Forty-nine members of the research group on inflammatory bowel disease in Japan were asked to answer a questionnaire regarding educational brochures for CD patients. We obtained 15 Japanese and three foreign brochures and conducted content analyses for seven global brochures. We received 34 replies. Only 15 (44%) of 34 hospitals gave the brochures to all newly diagnosed CD patients. In the Japanese brochures, a lot of content was devoted to nutrition therapy and self-management in terms of diet. On the contrary, foreign brochures devoted more content to symptoms and drug therapy. The existing approaches for providing information in Japanese hospitals were unsatisfactory. Furthermore, Japanese educational brochures for CD patients emphasized nutritional therapy and dietary restriction. This reflected the differences in treatment strategies among countries.

Mutual information and the fidelity of response of gene regulatory models

We investigate cellular response to extracellular signals by using information theory techniques motivated by recent experiments. We present results for the steady state of the following gene regulatory models found in both prokaryotic and eukaryotic cells: a linear transcription-translation model and a positive or negative auto-regulatory model. We calculate both the information capacity and the mutual information exactly for simple models and approximately for the full model. We find that (1) small changes in mutual information can lead to potentially important changes in cellular response and (2) there are diminishing returns in the fidelity of response as the mutual information increases. We calculate the information capacity using Gillespie simulations of a model for the TNF-α-NF-κ B network and find good agreement with the measured value for an experimental realization of this network. Our results provide a quantitative understanding of the differences in cellular response when comparing experimentally measured mutual information values of different gene regulatory models. Our calculations demonstrate that Gillespie simulations can be used to compute the mutual information of more complex gene regulatory models, providing a potentially useful tool in synthetic biology.

Information systems are used by most states to maintain registries of immunization data both for monitoring population-level adherence and for use in clinical practice and research. Direct data exchange between such systems and electronic health record systems presents an opportunity to improve the completeness and quality of information available. Our goals were to describe and compare the completeness of the Arizona State Immunization System, the electronic health record at a large community health provider in Arizona exchanging electronic data with the Arizona system, and personal immunization records in an effort to contribute to the discussion on the completeness of state-run immunization registries and data exchange with these registries. Immunization histories from these sources were collected and reviewed sequentially. Unique dates of vaccination administrations were counted for each patient and tagged on the basis of comparisons across sources. We quantified completeness by combining information from all 3 sources and comparing each source with the complete set. We determined that the state registry was 71.8% complete, the hospital electronic health record was 81.9% complete, and personal records were 87.8% complete. Of the 2017 unique vaccination administrations, 65% were present in all 3 sources, 24.6% in 2 of the 3 sources, and 10.4% in only 1 source. Only 11% of patients had records in complete agreement across the 3 sources. This study highlights issues related to data completeness, exchange, and reporting of immunization information to state registries and suggests that there is some degree of deficiency in completeness of immunization registries and other sources. This study indicates that there is a need to strengthen links between electronic data sources with immunization information and describes potential improvements in completeness that such efforts could provide, enabling providers to better rely on state immunization registries and to improve research utilization of immunization information systems.

Atlas selection for hippocampus segmentation: Relevance evaluation of three meta-information parameters.

PubMed

Dill, Vanderson; Klein, Pedro Costa; Franco, Alexandre Rosa; Pinho, Márcio Sarroglia

2018-04-01

Current state-of-the-art methods for whole and subfield hippocampus segmentation use pre-segmented templates, also known as atlases, in the pre-processing stages. Typically, the input image is registered to the template, which provides prior information for the segmentation process. Using a single standard atlas increases the difficulty in dealing with individuals who have a brain anatomy that is morphologically different from the atlas, especially in older brains. To increase the segmentation precision in these cases, without any manual intervention, multiple atlases can be used. However, registration to many templates leads to a high computational cost. Researchers have proposed to use an atlas pre-selection technique based on meta-information followed by the selection of an atlas based on image similarity. Unfortunately, this method also presents a high computational cost due to the image-similarity process. Thus, it is desirable to pre-select a smaller number of atlases as long as this does not impact on the segmentation quality. To pick out an atlas that provides the best registration, we evaluate the use of three meta-information parameters (medical condition, age range, and gender) to choose the atlas. In this work, 24 atlases were defined and each is based on the combination of the three meta-information parameters. These atlases were used to segment 352 vol from the Alzheimer's Disease Neuroimaging Initiative (ADNI) database. Hippocampus segmentation with each of these atlases was evaluated and compared to reference segmentations of the hippocampus, which are available from ADNI. The use of atlas selection by meta-information led to a significant gain in the Dice similarity coefficient, which reached 0.68 ± 0.11, compared to 0.62 ± 0.12 when using only the standard MNI152 atlas. Statistical analysis showed that the three meta-information parameters provided a significant improvement in the segmentation accuracy. Copyright © 2018 Elsevier Ltd. All rights reserved.

This study was conducted to compare the performance of three types of chairs in a low-resource setting. The larger goal was to provide information which will enable more effective use of limited funds by wheelchair manufacturers and suppliers in low-resource settings. The Motivation Rough Terrain and Whirlwind Rough Rider were compared in six skills tests which participants completed in one wheelchair type and then a day later in the other. A hospital-style folding transport wheelchair was also included in one test. For all skills, participants rated the ease or difficulty on a visual analogue scale. For all tracks, distance traveled and the physiological cost index were recorded. Data were analyzed using repeated measures analysis of variance. The Motivation wheelchair outperformed Whirlwind wheelchair on rough and smooth tracks, and in some metrics on the tight spaces track. Motivation and Whirlwind wheelchairs significantly outperformed the hospital transport wheelchair in all metrics on the rough track skills test. This comparative study provides data that are valuable for manufacturers and for those who provide wheelchairs to users. The comparison with the hospital-style transport chair confirms the cost to users of inappropriate wheelchair provision. Implications for Rehabilitation For those with compromised lower limb function, wheelchairs are essential to enable full participation and improved quality of life. Therefore, provision of wheelchairs which effectively enable mobility in the cultures and environments in which people with disabilities live is crucial. This includes low-resource settings where the need for appropriate seating is especially urgent. A repeated measures study to measure wheelchair performances in everyday skills in the setting where wheelchairs are used gives information on the quality of mobility provided by those wheelchairs. This study highlights differences in the performance of three types of wheelchairs often distributed in low-resource settings. This information can improve mobility for wheelchair users in those settings by enabling wheelchair manufacturers to optimize wheelchair design and providers to optimize the use of limited funds.

Differing Strategies to Meet Information‐Sharing Needs: Publicly Supported Community Health Information Exchanges Versus Health Systems’ Enterprise Health Information Exchanges

PubMed Central

KASH, BITA A.

2016-01-01

Policy Points: Community health information exchanges have the characteristics of a public good, and they support population health initiatives at the state and national levels. However, current policy equally incentivizes health systems to create their own information exchanges covering more narrowly defined populations.Noninteroperable electronic health records and vendors’ expensive custom interfaces are hindering health information exchanges. Moreover, vendors are imposing the costs of interoperability on health systems and community health information exchanges.Health systems are creating networks of targeted physicians and facilities by funding connections to their own enterprise health information exchanges. These private networks may change referral patterns and foster more integration with outpatient providers. Context The United States has invested billions of dollars to encourage the adoption of and implement the information technologies necessary for health information exchange (HIE), enabling providers to efficiently and effectively share patient information with other providers. Health care providers now have multiple options for obtaining and sharing patient information. Community HIEs facilitate information sharing for a broad group of providers within a region. Enterprise HIEs are operated by health systems and share information among affiliated hospitals and providers. We sought to identify why hospitals and health systems choose either to participate in community HIEs or to establish enterprise HIEs. Methods We conducted semistructured interviews with 40 policymakers, community and enterprise HIE leaders, and health care executives from 19 different organizations. Our qualitative analysis used a general inductive and comparative approach to identify factors influencing participation in, and the success of, each approach to HIE. Findings Enterprise HIEs support health systems' strategic goals through the control of an information technology network consisting of desired trading partners. Community HIEs support obtaining patient information from the broadest set of providers, but with more dispersed benefits to all participants, the community, and patients. Although not an either/or decision, community and enterprise HIEs compete for finite organizational resources like time, skilled staff, and money. Both approaches face challenges due to vendor costs and less‐than‐interoperable technology. Conclusions Both community and enterprise HIEs support aggregating clinical data and following patients across settings. Although they can be complementary, community and enterprise HIEs nonetheless compete for providers’ attention and organizational resources. Health policymakers might try to encourage the type of widespread information exchange pursued by community HIEs, but the business case for enterprise HIEs clearly is stronger. The sustainability of a community HIE, potentially a public good, may necessitate ongoing public funding and supportive regulation. PMID:26994710

This study is descriptive and analytical survey and the information gathering was through the questionnaireand the samples, based on the random of Kerjesi and Morgan Table sample size determination that was selected through stratified sampling proportionately to the size of the departments which summed up to 155 of which 113 responded to the mailed questionnaire. The results of the study show that among the various data sources such as books, journals and internet, faculty members have more undemandingand convenient access to the Internet compared to other resources use, however, half of the information needs of faculty members, 57 (50.4 percent) are provided by the printed books;and the databases available to the University and used by faculty members are PubMed with 76.1% and Science direct with 53.1% and Iranmedex with 46.9%.Only 17% of faculty members have the absolute contentment of the Internet information services,and more than half of the respondents (58.4%) expressed the low speed of Internet service as their major reason for their dissatisfaction of the provided services. Use and Satisfaction of Internet-Based Information Services of Faculty Members. Using the Internet to provide the needed information with an index of 46%is a significant issue. The results of the study show that among the various data sources such as books, journals and internet, faculty members have more undemandingand convenient access to the Internet and their access to printed books was really hard and limited, although the internet was more convenient to acquire information, most of the information needs of faculty members are provided by the printed books based on what they expressed. The study showed that the use and acquaintance of the sample of the information databases is very lowand only a few of them have the full satisfaction of the provided Internet information services and the main foremost reason for this major dissatisfaction is the low-speed Internet services at the University.

Prenatal maternal serum screening allows assessment of risk of chromosomal abnormalities in the fetus and is increasingly being offered to all women regardless of age or prior risk. However ensuring informed choice to participate in screening is difficult and the psychological implications of making an informed decision are uncertain. The aim of this study was to compare the growth of maternal-fetal emotional attachment in groups of women whose decisions about participation in screening were informed or not informed. A prospective longitudinal design was used. English speaking women were recruited in antenatal clinics prior to the offer of second trimester maternal screening. Three self-report questionnaires completed over the course of pregnancy used validated measures of informed choice and maternal-fetal emotional attachment. Attachment scores throughout pregnancy in informed and not-informed groups were compared in repeated measures analysis. 134 completed the first assessment (recruitment 73%) and 68 (58%) provided compete data. The informed group had significantly lower attachment scores (p = 0.023) than the not-informed group prior to testing, but scores were similar (p = 0.482) after test results were known. The findings raise questions about the impact of delayed maternal-fetal attachment and appropriate interventions to facilitate informed choice to participate in screening.

Objective: The research provides an understanding of pandemic information needs and informs professional development initiatives for librarians in disaster medicine. Methods: Utilizing a multisite, comparative case series design, the researchers conducted semi-structured interviews and examined supplementary materials in the form of organizational documents, correspondence, and websites to create a complete picture of each case. The rigor of the case series was ensured through data and investigator triangulation. Interview transcripts were coded using NVivo to identify common themes and points of comparison. Results: Comparison of the four cases revealed a distinct difference between “client-initiated” and “librarian-initiated” provision of pandemic information. Librarian-initiated projects utilized social software to “push” information, whereas client-initiated projects operated within patron-determined parameters to deliver information. Health care administrators were identified as a key audience for pandemic information, and news agencies were utilized as essential information sources. Librarians' skills at evaluating available information proved crucial for selecting best-quality evidence to support administrative decision making. Conclusions: Qualitative analysis resulted in increased understanding of pandemic information needs and identified best practices for disseminating information during periods of high organizational stress caused by an influx of new cases of an unknown infectious disease.

Objective The research determined the usage and satisfaction levels with one of two point-of-care (PoC) resources among health care providers in a rural state. Methods In this randomized controlled trial, twenty-eight health care providers in rural areas were stratified by occupation and region, then randomized into either the DynaMed or the AccessMedicine study arm. Study participants were physicians, physician assistants, and nurses. A pre- and post-study survey measured participants' attitudes toward different information resources and their information-seeking activities. Medical student investigators provided training and technical support for participants. Data analyses consisted of analysis of variance (ANOVA), paired t tests, and Cohen's d statistic to compare pre- and post-study effects sizes. Results Participants in both the DynaMed and the AccessMedicine arms of the study reported increased satisfaction with their respective PoC resource, as expected. Participants in both arms also reported that they saved time in finding needed information. At baseline, both arms reported too little information available, which increased to “about right amounts of information” at the completion of the study. DynaMed users reported a Cohen's d increase of +1.50 compared to AccessMedicine users' reported use of 0.82. DynaMed users reported d2 satisfaction increases of 9.48 versus AccessMedicine satisfaction increases of 0.59 using a Cohen's d. Conclusion Participants in the DynaMed arm of the study used this clinically oriented PoC more heavily than the users of the textbook-based AccessMedicine. In terms of user satisfaction, DynaMed users reported higher levels of satisfaction than the users of AccessMedicine. PMID:26807050

Vision can recalibrate the vestibular reafference signal used to re-establish postural equilibrium following a platform perturbation.

Visuo-vestibular recalibration, in which visual information is used to alter the interpretation of vestibular signals, has been shown to influence both oculomotor control and navigation. Here we investigate whether vision can recalibrate the vestibular feedback used during the re-establishment of equilibrium following a perturbation. The perturbation recovery responses of nine participants were examined following exposure to a period of 11 s of galvanic vestibular stimulation (GVS). During GVS in VISION trials, occlusion spectacles provided 4 s of visual information that enabled participants to correct for the GVS-induced tilt and associate this asymmetric vestibular signal with a visually provided 'upright'. NoVISION trials had no such visual experience. Participants used the visual information to assist in realigning their posture compared to when visual information was not provided (p < 0.01). The initial recovery response to a platform perturbation was not impacted by whether vision had been provided during the preceding GVS, as determined by peak centre of mass and pressure deviations (p = 0.09). However, after using vision to reinterpret the vestibular signal during GVS, final centre of mass and pressure equilibrium positions were significantly shifted compared to trials in which vision was not available (p < 0.01). These findings support previous work identifying a prominent role of vestibular input for re-establishing postural equilibrium following a perturbation. Our work is the first to highlight the capacity for visual feedback to recalibrate the vertical interpretation of vestibular reafference for re-establishing equilibrium following a perturbation. This demonstrates the rapid adaptability of the vestibular reafference signal for postural control.

Value of information analysis has been proposed as an alternative to the standard hypothesis testing approach, which is based on type I and type II errors, in determining sample sizes for randomized clinical trials. However, in addition to sample size calculation, value of information analysis can optimize other aspects of research design such as possible comparator arms and alternative follow-up times, by considering trial designs that maximize the expected net benefit of research, which is the difference between the expected cost of the trial and the expected value of additional information. To apply value of information methods to the results of a pilot study on catheter securement devices to determine the optimal design of a future larger clinical trial. An economic evaluation was performed using data from a multi-arm randomized controlled pilot study comparing the efficacy of four types of catheter securement devices: standard polyurethane, tissue adhesive, bordered polyurethane and sutureless securement device. Probabilistic Monte Carlo simulation was used to characterize uncertainty surrounding the study results and to calculate the expected value of additional information. To guide the optimal future trial design, the expected costs and benefits of the alternative trial designs were estimated and compared. Analysis of the value of further information indicated that a randomized controlled trial on catheter securement devices is potentially worthwhile. Among the possible designs for the future trial, a four-arm study with 220 patients/arm would provide the highest expected net benefit corresponding to 130% return-on-investment. The initially considered design of 388 patients/arm, based on hypothesis testing calculations, would provide lower net benefit with return-on-investment of 79%. Cost-effectiveness and value of information analyses were based on the data from a single pilot trial which might affect the accuracy of our uncertainty estimation. Another limitation was that different follow-up durations for the larger trial were not evaluated. The value of information approach allows efficient trial design by maximizing the expected net benefit of additional research. This approach should be considered early in the design of randomized clinical trials. © The Author(s) 2014.

2014-01-01

This study aims to measure the causal effect of informal caregiving on the health and health care use of women who are caregivers, using instrumental variables. We use data from South Korea, where daughters and daughters-in-law are the prevalent source of caregivers for frail elderly parents and parents-in-law. A key insight of our instrumental variable approach is that having a parent-in-law with functional limitations increases the probability of providing informal care to that parent-in-law, but a parent-in-law’s functional limitation does not directly affect the daughter-in-law’s health. We compare results for the daughter-in-law and daughter samples to check the assumption of the excludability of the instruments for the daughter sample. Our results show that providing informal care has significant adverse effects along multiple dimensions of health for daughter-in-law and daughter caregivers in South Korea. PMID:24753386

Authenticated key agreements for telecare medicine information systems provide patients, doctors, nurses and health visitors with accessing medical information systems and getting remote services efficiently and conveniently through an open network. In order to have higher security, many authenticated key agreement schemes appended biometric keys to realize identification except for using passwords and smartcards. Due to too many transmissions and computational costs, these authenticated key agreement schemes are inefficient in communication and computation. This investigation develops two secure and efficient authenticated key agreement schemes for telecare medicine information systems by using biometric key and extended chaotic maps. One scheme is synchronization-based, while the other nonce-based. Compared to related approaches, the proposed schemes not only retain the same security properties with previous schemes, but also provide users with privacy protection and have fewer transmissions and lower computational cost.

Analysis of volatile organic compounds (VOCs) is a promising approach for non-invasive, fast and potentially inexpensive diagnostics. Here, we present a new methodology for profiling the body chemistry by using the volatile fraction of molecules in various body fluids. Using mass spectrometry and cross-reactive nanomaterial-based sensors array, we demonstrate that simultaneous VOC detection from breath and skin would provide complementary, non-correlated information of the body's volatile metabolites profile. Eventually with further wide population validation studies, such a methodology could provide more accurate monitoring of pathological changes compared to the information provided by a single body fluid. The qualitative and quantitative methods presented here offers a variety of options for novel mapping of the metabolic properties of complex organisms, including humans. PMID:24714440

This paper explores methodology issues encountered in the analysis of flightcrew communications in aviation simulation research. Examples are provided by two recent studies which are compared on three issues: level of analysis, data definition, and interpretation of the results. The data discussed were collected in a study comparing two levels of aircraft automation. The first example is an investigation of how pilots' information transfer strategies differed as a function of automation during low and high-workload flight phases. The second study focuses on how crews managed actions in the two aircraft during a ten minute, high-workload flight segment. Results indicated that crews in the two aircraft differed in their strategies of information and action management. The differences are discussed in terms of their operational and research significance.

This study examined discharge planning practices by hospital providers for 17,053 psychiatric discharges in New York's statewide Medicaid program. Claims data were linked to information reported to New York State by managed behavioral health care organizations (MBHOs) conducting inpatient utilization reviews. MBHOs documented hospital providers' reports of the presence of three discharge planning practices for each discharge: communicating with an outpatient provider prior to discharge, scheduling an aftercare appointment, and forwarding a discharge summary. Hospital providers reported completing at least one of the three discharge planning practices for 85% of discharges. Individuals who received all three discharge planning practices had a higher likelihood of follow-up and kept their first outpatient follow-up visit at almost twice the speed compared with individuals who received none of the practices (hazard ratio=1.96, p<.001). This study provided baseline information concerning routine discharge planning practices and their relationship to timeliness of care transitions.

Beliefs about the relative harmfulness of one product compared to another (perceived relative harm) are central to research and regulation concerning tobacco and nicotine-containing products, but techniques for measuring such beliefs vary widely. We compared the validity of direct and indirect measures of perceived harm of e-cigarettes and smokeless tobacco (SLT) compared to cigarettes. On direct measures, participants explicitly compare the harmfulness of each product. On indirect measures, participants rate the harmfulness of each product separately, and ratings are compared. The U.S. Health Information National Trends Survey (HINTS-FDA-2015; N=3738) included direct measures of perceived harm of e-cigarettes and SLT compared to cigarettes. Indirect measures were created by comparing ratings of harm from e-cigarettes, SLT, and cigarettes on 3-point scales. Logistic regressions tested validity by assessing whether direct and indirect measures were associated with criterion variables including: ever-trying e-cigarettes, ever-trying snus, and SLT use status. Compared to the indirect measures, the direct measures of harm were more consistently associated with criterion variables. On direct measures, 26% of adults rated e-cigarettes as less harmful than cigarettes, and 11% rated SLT as less harmful than cigarettes. Direct measures appear to provide valid information about individuals’ harm beliefs, which may be used to inform research and tobacco control policy. Further validation research is encouraged.

Introduction: The important role of information and communication technologies and their influence on methods of storing, retrieving information in digital libraries, has not only changed the meanings behind classic library activates but has also created great changes in their services. However, it seems that not all digital libraries provide their users with similar services and only some of them are successful in fulfilling their role in digital environment. The Iranian National Medical library is among those that appear to come short compared to other digital libraries around the world. By knowing the different services provided by digital libraries worldwide, one can evaluate the services provided by Iranian National Medical library. The goal of this study is a comparison between Iranian National Medical library and digital libraries of selected countries. Materials and Methods: This is an applied study and uses descriptive – survey method. The statistical population is the digital libraries around the world which were actively providing library services between October and December 2011 and were selected by using the key word “Digital Library” in Google search engine. The data-gathering tool was direct access to the websites of these digital libraries. The statistical study is descriptive and Excel software was used for data analysis and plotting of the charts. Results: The findings showed that among the 33 digital libraries investigated worldwide, most of them provided Browse (87.87%), Search (84.84%), and Electronic information retrieval (57.57%) services. The “Help” in public services (48/48%) and “Interlibrary Loan” in traditional services (27/27%) had the highest frequency. The Iranian National Medical library provides more digital services compared to other libraries but has less classic and public services and has less than half of possible public services. Other than Iranian National Medical library, among the 33 libraries investigated, the leaders in providing different services are Library of University of California in classic services, Count Way Library of Medicine in digital services, and Library of Finland in public services. Results and Discussion: The results of this study show that among the digital libraries investigated, most provided similar public, digital, and classic services and The Iranian National Medical library has been somewhat successful in providing these services compared to other digital libraries. One can also conclude that the difference in services is at least in part due to difference in environments, information needs, and users. Conclusion: Iranian National Medical Library has been somewhat successful in providing library services in digital environment and needs to identify the services which are valuable to its users by identifying the users’ needs and special characteristics of its environment PMID:25540782

In settings like the Ebola epidemic, where proof-of-principle trials have provided evidence of efficacy but questions remain about the effectiveness of different possible modes of implementation, it may be useful to conduct trials that not only generate information about intervention effects but also themselves provide public health benefit. Cluster randomized trials are of particular value for infectious disease prevention research by virtue of their ability to capture both direct and indirect effects of intervention, the latter of which depends heavily on the nature of contact networks within and across clusters. By leveraging information about these networks-in particular the degree of connection across randomized units, which can be obtained at study baseline-we propose a novel class of connectivity-informed cluster trial designs that aim both to improve public health impact (speed of epidemic control) and to preserve the ability to detect intervention effects. We several designs for cluster randomized trials with staggered enrollment, in each of which the order of enrollment is based on the total number of ties (contacts) from individuals within a cluster to individuals in other clusters. Our designs can accommodate connectivity based either on the total number of external connections at baseline or on connections only to areas yet to receive the intervention. We further consider a "holdback" version of the designs in which control clusters are held back from re-randomization for some time interval. We investigate the performance of these designs in terms of epidemic control outcomes (time to end of epidemic and cumulative incidence) and power to detect intervention effect, by simulating vaccination trials during an SEIR-type epidemic outbreak using a network-structured agent-based model. We compare results to those of a traditional Stepped Wedge trial. In our simulation studies, connectivity-informed designs lead to a 20% reduction in cumulative incidence compared to comparable traditional study designs, but have little impact on epidemic length. Power to detect intervention effect is reduced in all connectivity-informed designs, but "holdback" versions provide power that is very close to that of a traditional Stepped Wedge approach. Incorporating information about cluster connectivity in the design of cluster randomized trials can increase their public health impact, especially in acute outbreak settings. Using this information helps control outbreaks-by minimizing the number of cross-cluster infections-with very modest cost in terms of power to detect effectiveness.

Objective The objective of this article is to assess the readability of leaflets about urological procedures provided by the British Association of Urological Surgeons (BAUS) to evaluate their suitability for providing information. Methods Information leaflets were assessed using three measures of readability: Flesch Reading Ease, Flesch-Kincaid and Simple Measure of Gobbledygook (SMOG) grade formulae. The scores were compared with national literacy statistics. Results Relatively good readability was demonstrated using the Flesch Reading Ease (53.4–60.1) and Flesch-Kincaid Grade Level (6.5–7.6) methods. However, the average SMOG index (14.0–15.0) for each category suggests that the majority of the leaflets are written above the reading level of an 18-year-old. Using national literacy statistics, at least 43% of the population will have significant difficultly understanding the majority of these leaflets. Conclusions The results suggest that comprehension of the leaflets provided by the BAUS is likely to be poor. These leaflets may be used as an adjunct to discussion but it is essential to ensure that all the information necessary to make an informed decision has been conveyed in a way that can be understood by the patient.

The goal of comparative effectiveness research is to assess medical therapies and allow patients, health care providers, payers, and policy makers to make evidence-based decisions about the most appropriate therapies in routine clinical practice. To conduct this type of research and to inform health care delivery, data about the impact of interventions on patient outcomes are needed. Methods of generating evidence for comparative effectiveness research provide opportunities to engage patients and understand their experiences with illness and its treatment. In this article we assess the need for, uses of, and strengths and weaknesses of patient-generated data. We also review in brief federal and medical society efforts to create new streams of patient-generated data for clinical and research use. We observe that the key to high-quality patient-generated data is to have immediate and actionable data so that patients experience the importance of the data for their own care as well as research purposes. We conclude that leveraging the emerging wealth of "big data" being generated by patient-facing technologies such as systems to collect patient-reported outcomes data and patient-worn sensors is critical to developing the evidence base that informs decisions made by patients, providers, and policy makers in pursuit of high-value medical care.

This paper provides significant ethnobotanical information on medicinal plant uses in the Zlatibor district, South-Western Serbia. A survey was performed using questionnaires with 220 informants (mean age 47, 79% female, 21% male). In addition, the use value and the relative importance of species were determined and the informant consensus factor was calculated for the medicinal plants included in the study. Intended plants usage was compared with previous ethnobotanical literature, with reference to the neighboring areas of Zlatibor district. The informants provided data for 69 medicinal plants belonging to 36 families. Rosaceae, Lamiaceae and Asteraceae were the predominant locally used families. The species with the highest use value were Mentha piperita, Matricaria chamomilla, Hypericum perforatum and Achillea millefolium. The most frequently reported medicinal uses were ones for treating gastrointestinal ailments, respiratory problems and skin diseases. Usually, the administration was primarily oral followed by topical applications. All different plant parts were utilized, however leaves were the most exploited parts of the plants. Folk medicine in South-Western Serbia, Zlatibor district is intended mainly as a mode of primary health care in healing of minor illnesses. The results indicate a slight reduction in the ethnobotanical and medical knowledge in this area, when compared with neighboring regions. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

The authors report on the development and calibration of item banks for depression, anxiety, and anger as part of the Patient-Reported Outcomes Measurement Information System (PROMIS®). Comprehensive literature searches yielded an initial bank of 1,404 items from 305 instruments. After qualitative item analysis (including focus groups and cognitive interviewing), 168 items (56 for each construct) were written in a first person, past tense format with a 7-day time frame and five response options reflecting frequency. The calibration sample included nearly 15,000 respondents. Final banks of 28, 29, and 29 items were calibrated for depression, anxiety, and anger, respectively, using item response theory. Test information curves showed that the PROMIS item banks provided more information than conventional measures in a range of severity from approximately −1 to +3 standard deviations (with higher scores indicating greater distress). Short forms consisting of seven to eight items provided information comparable to legacy measures containing more items. PMID:21697139

In vitro dissolution testing provides useful information at clinical and preclinical stages of the drug development process. The study includes pharmaceutical papers on dissolution research published in Polish journals between 2010 and 2015. They were analyzed with regard to information provided by authors about chosen methods, performed validation, statistical reporting or assumptions used to properly compare release profiles considering the present guideline documents addressed to dissolution methodology and its validation. Of all the papers included in the study, 23.86% presented at least one set of validation parameters, 63.64% gave the results of the weight uniformity test, 55.68% content determination, 97.73% dissolution testing conditions, and 50% discussed a comparison of release profiles. The assumptions for methods used to compare dissolution profiles were discussed in 6.82% of papers. By means of example analyses, we demonstrate that the outcome can be influenced by the violation of several assumptions or selection of an improper method to compare dissolution profiles. A clearer description of the procedures would undoubtedly increase the quality of papers in this area.

In order to assess the potential utility of guided patient self-assessment as an early preoperative triage tool, a computer-assisted questionnaire delivered by a non-clinician via telephone was 1) compared to face-to-face interview and examination by anaesthetists in outpatient clinics and 2) evaluated as a mechanism to stream patients to day of surgery assessment. In total, 514 patients scheduled for elective surgery in two tertiary public hospitals were assessed initially by telephone and then in an outpatient clinic. Both forms of assessment were marked by panels of specialist anaesthetists, who also provided an opinion on which patients would have been suitable to bypass preoperative anaesthetic outpatient assessment based upon information provided by the telephone interview. Overall, the quality of assessment provided by non-clinician telephone interview was comparable to face-to-face interview by anaesthetists, although more complex issues required face-to-face assessment. Panel review considered that 398 patients (60%) would not have required evaluation by an anaesthetist until the day of surgery, thus avoiding the need to separately attend a preoperative outpatient clinic. The sensitivity of telephone interview provided information to correctly classify patients as suitable for day of surgery evaluation was 98% (95% confidence interval 96 to 99%) with a specificity of 97% (95% confidence interval 92 to 98%). This study demonstrates that remote computer-assisted assessment can produce quality patient health information and enable early patient work-up and triage with the potential to reduce costs through more efficient use of resources.

The business end of health information technology. Can a fully integrated electronic health record increase provider productivity in a large community practice?

Electronic health records (EHRs) are expected to transform and improve the way medicine is practiced. However, providers perceive many barriers toward implementing new health information technology. Specifically, they are most concerned about the potentially negative impact on their practice finances and productivity. This study compares the productivity of 75 providers at a large urban primary care practice from January 2005 to February 2009, before and after implementing an EHR system, using longitudinal mixed model analyses. While decreases in productivity were observed at the time the EHR system was implemented, most providers quickly recovered, showing increases in productivity per month shortly after EHR implementation. Overall, providers had significant productivity increases of 1.7% per month per provider from pre- to post-EHR adoption. The majority of the productivity gains occurred after the practice instituted a pay-for-performance program, enabled by the data capture of the EHRs. Coupled with pay-for-performance, EHRs can spur rapid gains in provider productivity.

In Europe, Direct Healthcare Professional Communications (DHPCs) are important tools to inform healthcare professionals of serious, new drug safety issues. However, this tool has not always been successful in effectively communicating the desired actions to healthcare professionals. The aim of this study was to explore healthcare providers' experiences and their preferences for improvement of risk communication, comparing views of general practitioners (GPs), internists, community pharmacists and hospital pharmacists. A questionnaire was developed and pilot tested to assess experiences and preferences of Dutch healthcare professionals with DHPCs. The questionnaire and two reminders were sent to a random sample of 3488 GPs, internists and community and hospital pharmacists in the Netherlands. Descriptive statistics were used to describe demographic characteristics of the respondents. Chi squares, ANOVAs and the Wilcoxon signed rank test were used, when appropriate, to compare healthcare professional groups. The overall response rate was 34% (N = 1141, ranging from 24% for internists to 46% for community pharmacists). Healthcare providers trusted safety information more when provided by the Dutch Medicines Evaluation Board (MEB) than by the pharmaceutical industry. This was more the case for GPs than for the other healthcare professionals. Respondents preferred safety information to be issued by the MEB, the Dutch Pharmacovigilance Center or their own professional associations. The preferred alternative channels of drug safety information were e-mail, medical journals and electronic prescribing systems. Safety information of drugs does not always reach healthcare professionals through DHPCs. To improve current risk communication of drug safety issues, alternative and/or additional methods of risk communication should be developed using electronic methods and medical journals. Moreover, (additional) risk communication coming from an independent source such as the MEB should be considered. Special effort is needed to reach GPs.

Plant phenotypic data shrouds a wealth of information which, when accurately analysed and linked to other data types, brings to light the knowledge about the mechanisms of life. As phenotyping is a field of research comprising manifold, diverse and time-consuming experiments, the findings can be fostered by reusing and combining existing datasets. Their correct interpretation, and thus replicability, comparability and interoperability, is possible provided that the collected observations are equipped with an adequate set of metadata. So far there have been no common standards governing phenotypic data description, which hampered data exchange and reuse. In this paper we propose the guidelines for proper handling of the information about plant phenotyping experiments, in terms of both the recommended content of the description and its formatting. We provide a document called "Minimum Information About a Plant Phenotyping Experiment", which specifies what information about each experiment should be given, and a Phenotyping Configuration for the ISA-Tab format, which allows to practically organise this information within a dataset. We provide examples of ISA-Tab-formatted phenotypic data, and a general description of a few systems where the recommendations have been implemented. Acceptance of the rules described in this paper by the plant phenotyping community will help to achieve findable, accessible, interoperable and reusable data.

Little research has examined the antecedent characteristics of patients most likely to seek online cancer information. This study employs the Cognitive-Social Health Information Processing (C-SHIP) model as a framework to understand what psychosocial characteristics precede online cancer-related information seeking among rural breast cancer patients who often have fewer healthcare providers and limited local support services. Examining 144 patients who were provided free computer hardware, Internet access and training for how to use an Interactive Cancer Communication System, pre-test survey scores indicating patients’ psychosocial status were correlated with specific online cancer information seeking behaviors. Each of the factors specified by the C-SHIP model had significant relationships with online cancer information seeking behaviors with the strongest findings emerging for cancer-relevant encodings and self-construals, cancer-relevant beliefs and expectancies and cancer-relevant self-regulatory competencies and skills. Specifically, patients with more negative appraisals in these domains were more likely to seek out online cancer information. Additionally, antecedent variables associated with the C-SHIP model had more frequent relationships with experiential information as compared to didactic information. This study supports the applicability of the model to discern why people afflicted with cancer may seek online information to cope with their disease. PMID:18569368

Urban areas often lack rainfall information. To increase the number of rainfall observations in cities, microwave links from operational cellular telecommunication networks may be employed. Although this new potential source of rainfall information has been shown to be promising, its quality needs to be demonstrated more extensively. In the Rain Sense kickstart project of the Amsterdam Institute for Advanced Metropolitan Solutions (AMS), sensors and citizens are preparing Amsterdam for future weather. Part of this project is rainfall estimation using new measurement techniques. Innovative sensing techniques will be utilized such as rainfall estimation from microwave links, umbrellas for weather sensing, low-cost sensors at lamp posts and in drainage pipes for water level observation. These will be combined with information provided by citizens in an active way through smartphone apps and in a passive way through social media posts (Twitter, Flickr etc.). Sensor information will be integrated, visualized and made accessible to citizens to help raise citizen awareness of urban water management challenges and promote resilience by providing information on how citizens can contribute in addressing these. Moreover, citizens and businesses can benefit from reliable weather information in planning their social and commercial activities. In the end city-wide high-resolution rainfall maps will be derived, blending rainfall information from microwave links and weather radars. This information will be used for urban water management. This presentation focuses on rainfall estimation from commercial microwave links. Received signal levels from tens of microwave links within the Amsterdam region (roughly 1 million inhabitants) in the Netherlands are utilized to estimate rainfall with high spatial and temporal resolution. Rainfall maps will be presented and compared to a gauge-adjusted radar rainfall data set. Rainfall time series from gauge(s), radars and links will be compared.

Objectives Increasing use of medical devices outside of healthcare facilities inevitably requires connectivity and interoperability between medical devices and healthcare information systems. To this end, standards have been developed and used to provide interoperability between personal health devices (PHDs) and external systems. ISO/IEEE 11073 standards and IHE PCD-01 standard messages have been used the most in the exchange of observation data of health devices. Recently, transmitting observation data using the HL7 FHIR standard has been devised in the name of DoF (Devices on FHIR) and adopted very fast. We compare and analyze these standards and suggest that which standard will work best at the different environments of device usage. Methods We generated each message/resource of the three standards for observed vital signs from blood pressure monitor and thermometer. Then, the size, the contents, and the exchange processes of these messages are compared and analyzed. Results ISO/IEEE 11073 standard message has the smallest data size, but it has no ability to contain the key information, patient information. On the other hand, PCD-01 messages and FHIR standards have the fields for patient information. HL7 DoF standards provide reusing of information unit known as resource, and it is relatively easy to parse DoF messages since it uses widely known XML and JSON. Conclusions ISO/IEEE 11073 standards are suitable for devices having very small computing power. IHE PCD-01 and HL7 DoF messages can be used for the devices that need to be connected to hospital information systems that require patient information. When information reuse is frequent, DoF is advantageous over PCD-01. PMID:29503752

Data from the 1997 Robert Wood Johnson Foundation Employer Health Insurance Survey provide new information comparing public- and private-sector employee health benefits. The federal government is ahead of other employers in adopting managed competition principles using financial incentives and consumer information to promote choosing efficient plans. Federal employees experience a $200 annual compensation gap relative to those in the private sector, but it is partly explained by advantage in purchasing power. In contrast, state and local governments make higher payments toward health insurance than private-sector employers do. Their premiums are equivalent, but they pay a greater share of the total cost.

Stressful events early in life can affect children's mental health problems. Collecting valid and reliable information about children's bad experiences is important for research and clinical purposes. This study aimed to (1) investigate whether mothers and children provide valid reports of bullying victimization, (2) examine the inter-rater reliability between the two informants, (3) test the predictive validity of their reports with children's emotional and behavioral problems and (4) compare the genetic and environmental etiology of bullying victimization as reported by mothers and children. We assessed bullying victimization in the Environmental-Risk (E-Risk) Longitudinal Twin Study, a nationally-representative sample of 1,116 families with twins. We collected reports from mothers and children during private interviews, including detailed narratives. Findings showed that we can rely on mothers and children as informants of bullying victimization: both informants provided information which adhered to the definition of bullying as involving repeated hurtful actions between peers in the presence of a power imbalance. Although mothers and children modestly agreed with each other about who was bullied during primary and secondary school, reports of bullying victimization from both informants were similarly associated with children's emotional and behavioral problems and provided similar estimates of genetic and environmental influences. Findings from this study suggest that collecting information from multiple informants is ideal to capture all instances of bullying victimization. However, in the absence of child self-reports, mothers can be considered as a viable alternative, and vice versa.

In Japan, the cervical cancer screening rate is extremely low. Towards improving the cervical cancer screening rate, encouraging eligible people to make an informed choice, which is a decision-making process that relies on beliefs informed by adequate information about the possible benefits and risks of screening, has attracted increased attention in the public health domain. However, there is concern that providing information on possible risks of screening might prevent deter from participating. In total, 1,912 women aged 20-39 years who had not participated in screening in the fiscal year were selected from a Japanese urban community setting. Participants were randomly divided into 3 groups. Group A received a printed reminder with information about the possible benefits of screening, group B received a printed reminder with information about possible benefits and risks, and group C received a printed reminder with simple information only (control group). Out of 1,912 participants, 169 (8.8%) participated in cervical cancer screening. In the intervention groups, 137 (10.9%) participated in cervical cancer screening, compared to only 32 (4.9%) of the control group (p < 0.001). In addition, logistic regression analysis revealed that there was no significant difference in screening rate between group A and group B (p = 0.372). Providing information on the possible risks of screening may not prevent people from taking part in cervical cancer screening among a Japanese non-adherent population.

Environmental program performance information is in high demand, but little research suggests why conservation organizations differ in reporting performance information. We compared performance measurement and reporting by four private-land conservation organizations: Partners for Fish and Wildlife in the US Fish and Wildlife Service (national government), Forest Stewardship Council-US (national nonprofit organization), Land and Water Conservation Departments (local government), and land trusts (local nonprofit organization). We asked: (1) How did the pattern of performance reporting relationships vary across organizations? (2) Was political conflict among organizations' principals associated with greater performance information? and (3) Did performance information provide evidence of program effectiveness? Based on our typology of performance information, we found that most organizations reported output measures such as land area or number of contracts, some reported outcome indicators such as adherence to performance standards, but few modeled or measured environmental effects. Local government Land and Water Conservation Departments reported the most types of performance information, while local land trusts reported the fewest. The case studies suggest that governance networks influence the pattern and type of performance reporting, that goal conflict among principles is associated with greater performance information, and that performance information provides unreliable causal evidence of program effectiveness. Challenging simple prescriptions to generate more data as evidence, this analysis suggests (1) complex institutional and political contexts for environmental program performance and (2) the need to supplement performance measures with in-depth evaluations that can provide causal inferences about program effectiveness.

Stressful events early in life can affect children’s mental health problems. Collecting valid and reliable information about children’s bad experiences is important for research and clinical purposes. This study aimed to (1) investigate whether mothers and children provide valid reports of bullying victimization, (2) examine the inter-rater reliability between the two informants, (3) test the predictive validity of their reports with children’s emotional and behavioral problems and (4) compare the genetic and environmental etiology of bullying victimization as reported by mothers and children. We assessed bullying victimization in the Environmental-Risk (E-Risk) Longitudinal Twin Study, a nationally-representative sample of 1,116 families with twins. We collected reports from mothers and children during private interviews, including detailed narratives. Findings showed that we can rely on mothers and children as informants of bullying victimization: both informants provided information which adhered to the definition of bullying as involving repeated hurtful actions between peers in the presence of a power imbalance. Although mothers and children modestly agreed with each other about who was bullied during primary and secondary school, reports of bullying victimization from both informants were similarly associated with children’s emotional and behavioral problems and provided similar estimates of genetic and environmental influences. Findings from this study suggest that collecting information from multiple informants is ideal to capture all instances of bullying victimization. However, in the absence of child self-reports, mothers can be considered as a viable alternative, and vice versa. PMID:20938734

Child maltreatment is a serious public health concern, and its detrimental effects can be compounded by traumatic experiences associated with the child welfare (CW) system. Trauma-informed care (TIC) is a promising strategy for addressing traumatized children's needs, but research on the impact of TIC in CW is limited. This study examines initial findings of the Massachusetts Child Trauma Project, a statewide TIC initiative in the CW system and mental health network. After 1 year of implementation, Trauma-Informed Leadership Teams in CW offices emerged as key structures for TIC systems integration, and mental health providers' participation in evidence-based treatment (EBT) learning collaboratives was linked to improvements in trauma-informed individual and agency practices. After approximately 6 months of EBT treatment, children had fewer posttraumatic symptoms and behavior problems compared to baseline. Barriers to TIC that emerged included scarce resources for trauma-related work in the CW agency and few mental providers providing EBTs to young children. Future research might explore variations in TIC across service system components as well as the potential for differential effects across EBT models disseminated through TIC. © The Author(s) 2015.

This study employed the selective trust paradigm to examine how children interpret novel labels when compared with labels they already know to be accurate or inaccurate within the biological domain. The participants--3-, 4-, and 5-year-olds (N=144)--were allocated to one of three conditions. In the accurate versus inaccurate condition, one informant labeled body parts correctly, whereas the other labeled them incorrectly (e.g., calling an eye an "arm"). In the accurate versus novel condition, one informant labeled body parts accurately, whereas the other provided novel labels (e.g., calling an eye a "roke"). Finally, in the inaccurate versus novel condition, one informant labeled body parts incorrectly, whereas the other offered novel labels. In subsequent test trials, the two informants provided conflicting labels for unfamiliar internal organs. In the accurate versus inaccurate condition, children sought and endorsed labels from the accurate informant. In the accurate versus novel condition, only 4- and 5-year-olds preferred the accurate informant, whereas 3-year-olds did not selectively prefer either informant. In the inaccurate versus novel condition, only 5-year-olds preferred the novel informant, whereas 3- and 4-year-olds did not demonstrate a selective preference. Results are supportive of previous studies suggesting that 3-year-olds are sensitive to inaccuracy and that 4-year-olds privilege accuracy. However, 3- and 4-year-olds appear to be unsure as to how the novel informant should be construed. In contrast, 5-year-olds appreciate that speakers offering new information are more trustworthy than those offering inaccurate information, but they are cautious in judging such informants as being "better" at providing that information.

BACKGROUND/OBJECTIVES To encourage healthier food choices for children in fast-food restaurants, many initiatives have been proposed. This study aimed to examine the effect of disclosing nutritional information on parents' meal choices for their children at fast-food restaurants in South Korea. SUBJECTS/METHODS An online experimental survey using a menu board was conducted with 242 parents of children aged 2-12 years who dined with them at fast-food restaurants at least once a month. Participants were classified into two groups: the low-calorie group (n = 41) who chose at least one of the lowest calorie meals in each menu category, and the high-calorie group (n = 201) who did not. The attributes including perceived empowerment, use of provided nutritional information, and perceived difficulties were compared between the two groups. RESULTS The low-calorie group perceived significantly higher empowerment with the nutritional information provided than did the high-calorie group (P = 0.020). Additionally, the low-calorie group was more interested in nutrition labeling (P < 0.001) and considered the nutritional value of menus when selecting restaurants for their children more than did the high-calorie group (P = 0.017). The low-calorie group used the nutritional information provided when choosing meals for their children significantly more than did the high-calorie group (P < 0.001), but the high-calorie group had greater difficulty using the nutritional information provided (P = 0.012). CONCLUSIONS The results suggest that improving the empowerment of parents using nutritional information could be a strategy for promoting healthier parental food choices for their children at fast-food restaurants.

Angulo-Martinez, Marta; Begueria, Santiago; Latorre, Borja

2017-04-01

Optical disdrometers are present weather sensors with the ability of providing integrate information of precipitation like intensity and reflectivity together with discrete information of drop sizes and velocities distribution (DSVD) of the hydrometeors crossing the laser beam sampling area. These sensors constitute a step forward in comparison with pluviometers towards a more complete characterisation of precipitation. Their use is spreading in many research fields for several applications. Understanding the differences from one another helps in the election of the sensor and point out limitations to be fixed in future versions. Four collocated optical disdrometers, two Laser Precipitation Monitors (LPM-Thies Clima) and two PARSIVEL, 1-minute measurements of 800 natural rainfall events were compared. Results showed a general agreement in integrated variables, like intensity or liquid water content. Nevertheless, comparing raw data, as the number of particles and DSVD, great differences were found. LPM generally measures more and smaller drops than PARSIVEL and this difference increases with rainfall intensity. These results may affect especially the reflectivity value every disdrometer provide. A complete description of the measurements obtained, quantifiying the differences is provided, indicating their possible sources.

Most publications about breast cancer do not provide accurate and comprehensive information, giving few or no data about risk/benefit ratios. We conducted a comparative study among 10 European countries about health information on breast cancer screening, assessing the first 10 Web sites addressing the general public that appeared following an Internet search.With the help of medical residents involved in the EuroNet MRPH Association, we analyzed the first 30 results of an Internet search in 10 European countries to determine the first 10 sites that offered screening mammography. We searched for the following information: source of information, general information on mammography and breast cancer screening, potential harms and risks (false positives, false positives after biopsy, false negatives, interval cancer, overdiagnosis, lead-time bias, and radiation exposure), and potential benefits (reduced mortality and increased survival).The United Kingdom provided the most information: 39 of all 70 possible identified risks (56%) were reported on its sites. Five nations presented over 35% of the possible information (United Kingdom, Spain, France, Ireland, and Italy); the others were under 30% (Portugal, Poland, Slovenia, Netherlands, and Croatia). Regarding the benefits, sites offering the most complete information were those in France (95%) and Poland (90%).Our results suggest that, despite consensus in the scientific community about providing better information to citizens, further efforts are needed to improve information about breast cancer screening. That conclusion also applies to countries showing better results. We believe that there should be greater coordination in this regard throughout Europe.

Due to the increasing number of text mining resources (tools and corpora) available to biologists, interoperability issues between these resources are becoming significant obstacles to using them effectively. UIMA, the Unstructured Information Management Architecture, is an open framework designed to aid in the construction of more interoperable tools. U-Compare is built on top of the UIMA framework, and provides both a concrete framework for out-of-the-box text mining and a sophisticated evaluation platform allowing users to run specific tools on any target text, generating both detailed statistics and instance-based visualizations of outputs. U-Compare is a joint project, providing the world's largest, and still growing, collection of UIMA-compatible resources. These resources, originally developed by different groups for a variety of domains, include many famous tools and corpora. U-Compare can be launched straight from the web, without needing to be manually installed. All U-Compare components are provided ready-to-use and can be combined easily via a drag-and-drop interface without any programming. External UIMA components can also simply be mixed with U-Compare components, without distinguishing between locally and remotely deployed resources. http://u-compare.org/

Cervical cancer is the most common gynaecologic malignancy worldwide and is the sixth cause of cancer death in Chile. Human papillomavirus (HPV) is responsible for most cervical cancers. Individuals seeking basic information about HPV frequently turn to health information websites. We hypothesized that some of their data may be inaccurate. Comparative analysis of information. We analyze the content of highly accessed websites such as the Spanish version of Wikipedia and Yahoo Answers through the application of a questionnaire, as well as a website managed by the Chilean Ministry of Health (Minsal). The accuracy of each answer was confirmed by comparison with information retrieved from articles published by indexed journals. The information provided by the Spanish version of Wikipedia was accurate; nevertheless a few omissions were detected. The quality of the information provided by the Spanish version of Yahoo Answers was inaccurate and confusing. The Minsal website lacked important information on several topics about HPV even though it is managed and endorsed by the government. We suggest periodical content reviews to increase the completeness, transparency and correctness of the website. Copyright © 2017 The Royal Society for Public Health. Published by Elsevier Ltd.

Can high quality overcome consumer resistance to restricted provider access? Evidence from a health plan choice experiment.

PubMed

Harris, Katherine M

2002-06-01

To investigate the impact of quality information on the willingness of consumers to enroll in health plans that restrict provider access. A survey administered to respondents between the ages of 25 and 64 in the West Los Angeles area with private health insurance. An experimental approach is used to measure the effect of variation in provider network features and information about the quality of network physicians on hypothetical plan choices. Conditional logit models are used to analyze the experimental choice data. Next, choice model parameter estimates are used to simulate the impact of changes in plan features on the market shares of competing health plans and to calculate the quality level required to make consumers indifferent to changes in provider access. The presence of quality information reduced the importance of provider network features in plan choices as hypothesized. However, there were not statistically meaningful differences by type of quality measure (i.e., consumer assessed versus expert assessed). The results imply that large quality differences are required to make consumers indifferent to changes in provider access. The impact of quality on plan choices depended more on the particular measure and less on the type of measure. Quality ratings based on the proportion of survey respondents "extremely satisfied with results of care" had the greatest impact on plan choice while the proportion of network doctors "affiliated with university medical centers" had the least. Other consumer and expert assessed measures had more comparable effects. Overall the results provide empirical evidence that consumers are willing to trade high quality for restrictions on provider access. This willingness to trade implies that relatively small plans that place restrictions on provider access can successfully compete against less restrictive plans when they can demonstrate high quality. However, the results of this study suggest that in many cases, the level of quality required for consumers to accept access restrictions may be so high as to be unattainable. The results provide empirical support for the current focus of decision support efforts on consumer assessed quality measures. At the same time, however, the results suggest that consumers would also value quality measures based on expert assessments. This finding is relevant given the lack of comparative quality information based on expert judgment and research suggesting that consumers have apprehensions about their ability to meaningfully interpret performance-based quality measures.

What do evaluation instruments tell us about the quality of complementary medicine information on the internet?

Developers of health information websites aimed at consumers need methods to assess whether their website is of "high quality." Due to the nature of complementary medicine, website information is diverse and may be of poor quality. Various methods have been used to assess the quality of websites, the two main approaches being (1) to compare the content against some gold standard, and (2) to rate various aspects of the site using an assessment tool. We aimed to review available evaluation instruments to assess their performance when used by a researcher to evaluate websites containing information on complementary medicine and breast cancer. In particular, we wanted to see if instruments used the same criteria, agreed on the ranking of websites, were easy to use by a researcher, and if use of a single tool was sufficient to assess website quality. Bibliographic databases, search engines, and citation searches were used to identify evaluation instruments. Instruments were included that enabled users with no subject knowledge to make an objective assessment of a website containing health information. The elements of each instrument were compared to nine main criteria defined by a previous study. Google was used to search for complementary medicine and breast cancer sites. The first six results and a purposive six from different origins (charities, sponsored, commercial) were chosen. Each website was assessed using each tool, and the percentage of criteria successfully met was recorded. The ranking of the websites by each tool was compared. The use of the instruments by others was estimated by citation analysis and Google searching. A total of 39 instruments were identified, 12 of which met the inclusion criteria; the instruments contained between 4 and 43 questions. When applied to 12 websites, there was agreement of the rank order of the sites with 10 of the instruments. Instruments varied in the range of criteria they assessed and in their ease of use. Comparing the content of websites against a gold standard is time consuming and only feasible for very specific advice. Evaluation instruments offer gateway providers a method to assess websites. The checklist approach has face validity when results are compared to the actual content of "good" and "bad" websites. Although instruments differed in the range of items assessed, there was fair agreement between most available instruments. Some were easier to use than others, but these were not necessarily the instruments most widely used to date. Combining some of the better features of instruments to provide fewer, easy-to-use methods would be beneficial to gateway providers.

2013-01-01

Combining PET with MRI in a single system provides clinicians with complementary molecular and anatomical information. However, existing integrated PET/MRI systems do not have time-of-flight PET capabilities. This work describes an MRI-compatible front-end electronic system with ToF capabilities. The approach employs a fast arrival-time pickoff comparator to digitize the timing information, and a laser diode to drive a 10m fiber-optic cable to optically transmit asynchronous timing information to a photodiode receiver readout system. The comparator and this electo-optical link show a combined 11.5ps fwhm jitter in response to a fast digital pulse. When configured with LYSO scintillation crystals and Hamamatsu MPPC silicon photo-multipliers the comparator and electro-optical link achieved a 511keV coincidence time resolution of 254.7ps +/− 8.0ps fwhm with 3×3×20mm crystals and 166.5 +/− 2.5ps fwhm with 3×3×5mm crystals.

Classical statistical methods for analyzing exposure data with values below the detection limits are well described in the occupational hygiene literature, but an evaluation of a Bayesian approach for handling such data is currently lacking. Here, we first describe a Bayesian framework for analyzing censored data. We then present the results of a simulation study conducted to compare the β-substitution method with a Bayesian method for exposure datasets drawn from lognormal distributions and mixed lognormal distributions with varying sample sizes, geometric standard deviations (GSDs), and censoring for single and multiple limits of detection. For each set of factors, estimates for the arithmetic mean (AM), geometric mean, GSD, and the 95th percentile (X0.95) of the exposure distribution were obtained. We evaluated the performance of each method using relative bias, the root mean squared error (rMSE), and coverage (the proportion of the computed 95% uncertainty intervals containing the true value). The Bayesian method using non-informative priors and the β-substitution method were generally comparable in bias and rMSE when estimating the AM and GM. For the GSD and the 95th percentile, the Bayesian method with non-informative priors was more biased and had a higher rMSE than the β-substitution method, but use of more informative priors generally improved the Bayesian method's performance, making both the bias and the rMSE more comparable to the β-substitution method. An advantage of the Bayesian method is that it provided estimates of uncertainty for these parameters of interest and good coverage, whereas the β-substitution method only provided estimates of uncertainty for the AM, and coverage was not as consistent. Selection of one or the other method depends on the needs of the practitioner, the availability of prior information, and the distribution characteristics of the measurement data. We suggest the use of Bayesian methods if the practitioner has the computational resources and prior information, as the method would generally provide accurate estimates and also provides the distributions of all of the parameters, which could be useful for making decisions in some applications. © The Author 2015.

BACKGROUND Anemia is an early indicator of many diseases, yet blood donors with low hematocrit (Hct) often receive inadequate information about its medical importance. We sought to understand the types of information that are and should be provided to these donors. STUDY DESIGN AND METHODS Two companion studies were performed. The first investigated blood center practices for care of donors with low Hct including deferral length, information provided, and cutoff values used when referring donors for medical attention. The second was a randomized prospective pilot study comparing behavior of deferred donors receiving an “older” pamphlet providing a list of iron-rich foods or a “newer” pamphlet providing descriptions of common causes of anemia and advice for seeking medical attention. RESULTS More than 70% of centers defer donors for 1 day. Only 6% defer donors for more than 2 weeks. Most centers provide written and/or verbal information about low Hct. Only 35% have a cutoff value defining significant anemia that requires additional medical attention. In the study of donors with low Hct, significant disease was identified within 3 months after deferral in 2 of 104 subjects: metastatic lung cancer and acute lymphocytic leukemia. Only donors receiving the newer pamphlet reported that it “definitely improved” their ability to speak with their doctor about anemia. CONCLUSIONS The diagnosis of anemia in blood donors may be an indicator of significant undiagnosed disease. There are wide variations in how centers care for and educate donors with anemia. Donors with anemia should be provided improved and consistent educational information. PMID:20977487

Estimates of Soil Moisture Using the Land Information System for Land Surface Water Storage: Case Study for the Western States Water Mission

Soil moisture is one of the critical factors in terrestrial hydrology. Accurate soil moisture information improves estimation of terrestrial water storage and fluxes, that is essential for water resource management including sustainable groundwater pumping and agricultural irrigation practices. It is particularly important during dry periods when water stress is high. The Western States Water Mission (WSWM), a multiyear mission project of NASA's Jet Propulsion Laboratory, is operated to understand and estimate quantities of the water availability in the western United States by integrating observations and measurements from in-situ and remote sensing sensors, and hydrological models. WSWM data products have been used to assess and explore the adverse impacts of the California drought (2011-2016) and provide decision-makers information for water use planning. Although the observations are often more accurate, simulations using land surface models can provide water availability estimates at desired spatio-temporal scales. The Land Information System (LIS), developed by NASA's Goddard Space Flight Center, integrates developed land surface models and data processing and management tools, that enables to utilize the measurements and observations from various platforms as forcings in the high performance computing environment to forecast the hydrologic conditions. The goal of this study is to implement the LIS in the western United States for estimates of soil moisture. We will implement the NOAH-MP model at the 12km North America Land Data Assimilation System grid and compare to other land surface models included in the LIS. Findings will provide insight into the differences between model estimates and model physics. Outputs from a multi-model ensemble from LIS can also be used to enhance estimated reliability and provide quantification of uncertainty. We will compare the LIS-based soil moisture estimates to the SMAP enhanced 9 km soil moisture product to understand the mechanistic differences between the model and observation. These outcomes will contribute to the WSWM for providing robust products.

With the advent of Web 2.0 technologies, user-edited online resources such as Wikipedia are increasingly tapped for information. However, there is little research on the quality of health information found in Wikipedia. To compare the scope, completeness, and accuracy of drug information in Wikipedia with that of a free, online, traditionally edited database (Medscape Drug Reference [MDR]). Wikipedia and MDR were assessed on 8 categories of drug information. Questions were constructed and answers were verified with authoritative resources. Wikipedia and MDR were evaluated according to scope (breadth of coverage) and completeness. Accuracy was tracked by factual errors and errors of omission. Descriptive statistics were used to summarize the components. Fisher's exact test was used to compare scope and paired Student's t-test was used to compare current results in Wikipedia with entries 90 days prior to the current access. Wikipedia was able to answer significantly fewer drug information questions (40.0%) compared with MDR (82.5%; p < 0.001). Wikipedia performed poorly regarding information on dosing, with a score of 0% versus the MDR score of 90.0%. Answers found in Wikipedia were 76.0% complete, while MDR provided answers that were 95.5% complete; overall, Wikipedia answers were less complete than those in Medscape (p < 0.001). No factual errors were found in Wikipedia, whereas 4 answers in Medscape conflicted with the answer key; errors of omission were higher in Wikipedia (n = 48) than in MDR (n = 14). There was a marked improvement in Wikipedia over time, as current entries were superior to those 90 days prior (p = 0.024). Wikipedia has a more narrow scope, is less complete, and has more errors of omission than the comparator database. Wikipedia may be a useful point of engagement for consumers, but is not authoritative and should only be a supplemental source of drug information.

Measuring the performance of visual to auditory information conversion.

Tan, Shern Shiou; Maul, Tomás Henrique Bode; Mennie, Neil Russell

2013-01-01

Visual to auditory conversion systems have been in existence for several decades. Besides being among the front runners in providing visual capabilities to blind users, the auditory cues generated from image sonification systems are still easier to learn and adapt to compared to other similar techniques. Other advantages include low cost, easy customizability, and universality. However, every system developed so far has its own set of strengths and weaknesses. In order to improve these systems further, we propose an automated and quantitative method to measure the performance of such systems. With these quantitative measurements, it is possible to gauge the relative strengths and weaknesses of different systems and rank the systems accordingly. Performance is measured by both the interpretability and also the information preservation of visual to auditory conversions. Interpretability is measured by computing the correlation of inter image distance (IID) and inter sound distance (ISD) whereas the information preservation is computed by applying Information Theory to measure the entropy of both visual and corresponding auditory signals. These measurements provide a basis and some insights on how the systems work. With an automated interpretability measure as a standard, more image sonification systems can be developed, compared, and then improved. Even though the measure does not test systems as thoroughly as carefully designed psychological experiments, a quantitative measurement like the one proposed here can compare systems to a certain degree without incurring much cost. Underlying this research is the hope that a major breakthrough in image sonification systems will allow blind users to cost effectively regain enough visual functions to allow them to lead secure and productive lives.

Is a public reporting approach appropriate for nursing home care?

Publicizing quality information has been used as a quality improvement strategy in the acute care sector for more than a decade. Despite research showing mixed results of these efforts, publicly reporting quality measures is currently being pursued as a quality improvement strategy for nursing homes. Designed to empower consumers to make informed choices and to stimulate provider competition on quality, nursing home public reporting began in 1998 with the Nursing Home Compare Web site and has received greater emphasis in the 2002 Nursing Home Quality Initiative, both directed by the federal government. Focusing on the response of three key stakeholder groups across settings of care-consumers, providers, and purchasers-I identify several challenges that nursing home reporting must overcome to be successful. I conclude that publicly reporting quality measures for nursing homes will have a harder time promoting quality improvement than for acute care settings, where results have been disappointing thus far. In addition to the conceptual analysis, I evaluate whether the quality information reported on Nursing Home Compare had any impact on nursing home occupancy rates following its release. Using a pre/post-release design, I find that the effect of public reporting on nursing home occupancy rates has been minimal thus far. Although some estimates of effect are statistically significant and in the hypothesized direction, they all suggest very small effect sizes. It is unclear whether the absence of a larger reporting effect to date is specific to Nursing Home Compare or whether it inheres to the broader task of using quality information to promote change in the nursing home care sector.
