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

Objective: To describe consumer understanding of pharmacy quality measures and consumer preferences for pharmacy quality information. Methods: Semi-structured focus group design was combined with survey methods. Adults who filled prescription medications for self-reported chronic illnesses at community pharmacies discussed their understanding of Pharmacy Quality Alliance approved quality measures. Questions examined preference of pharmacy quality information rating systems (e.g. stars versus percentages) and desired data display/formats. During the focus group, participants completed a survey examining their understanding of each pharmacy quality measure. All focus group discussions were transcribed verbatim. Data were analyzed using thematic analysis and descriptive statistics. Results: Thirty-four individuals participated (mean age= 62.85; SD=16.05). Participants were unfamiliar with quality measures information and their level of understanding differed for each quality measure. Surveys indicated 94.1% understood “Drug-Drug Interactions” and “Helping Patients Get Needed Medications” better than other measures (e.g., 76.5% understood “Suboptimal Treatment of Hypertension in Patients with Diabetes”). Qualitative analysis indicated participants preferred an overall pharmacy rating for quick access and use. However, participants also wanted quality measures information displayed by health conditions. Participants favored comparison of their pharmacy to city data instead of state data. Most participants liked star ratings better than percentages, letter grades, or numerical ratings. Conclusions: Individuals who have a chronic illness and regularly use community pharmacies are interested in pharmacy quality measures. However, specific quality measures were not understood by some participants. Participants had specific preferences for the display of pharmacy quality information which will be helpful in the design of appropriate quality report systems. PMID

No previous studies have addressed the integrated relationships among system quality, service quality, job satisfaction, and system performance; this study attempts to bridge such a gap with evidence-based practice study. The convenience sampling method was applied to the information system users of three hospitals in southern Taiwan. A total of 500 copies of questionnaires were distributed, and 283 returned copies were valid, suggesting a valid response rate of 56.6%. SPSS 17.0 and AMOS 17.0 (structural equation modeling) statistical software packages were used for data analysis and processing. The findings are as follows: System quality has a positive influence on service quality (γ11= 0.55), job satisfaction (γ21= 0.32), and system performance (γ31= 0.47). Service quality (β31= 0.38) and job satisfaction (β32= 0.46) will positively influence system performance. It is thus recommended that the information office of hospitals and developers take enhancement of service quality and user satisfaction into consideration in addition to placing b on system quality and information quality when designing, developing, or purchasing an information system, in order to improve benefits and gain more achievements generated by hospital information systems.

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

2018-02-01

This research proposed a model combining an approach of Total Quality Management (TQM) and Fuzzy method of Service Quality (SERVQUAL) to asses service quality. TQM implementation was as quality management orienting on customer's satisfaction by involving all stakeholders. SERVQUAL model was used to measure quality service based on five dimensions such as tangible, reliability, responsiveness, assurance, and empathy. Fuzzy set theory was to accommodate subjectivity and ambiguity of quality assessment. Input data consisted of indicator data and quality assessment aspect. Input data was, then, processed to be service quality assessment questionnaires of Pesantren by using Fuzzy method to get service quality score. This process consisted of some steps as follows : inputting dimension and questionnaire data to data base system, filling questionnaire through system, then, system calculated fuzzification, defuzzification, gap of quality expected and received by service receivers, and calculating each dimension rating showing quality refinement priority. Rating of each quality dimension was, then, displayed at dashboard system to enable users to see information. From system having been built, it could be known that tangible dimension had the highest gap, -0.399, thus it needs to be prioritized and gets evaluation and refinement action soon.

The quality and readability of internet information regarding clavicle fractures.

2016-03-01

The internet has become a major source of health information for patients. However, there has been little scrutiny of health information available on the internet to the public. Our objectives were to evaluate the quality and readability of information available on the internet regarding clavicle fractures and whether they changed with academic affiliation of the website or with complexity of the search term. Through a prospective evaluation of 3 search engines using 3 different search terms of varying complexity ("broken collarbone," "collarbone fracture," and "clavicle fracture"), we evaluated 91 website hits for quality and readability. Websites were specifically analyzed by search term and by website type. Information quality was evaluated on a four-point scale, and information readability was assessed using the Flesch-Kincaid score for reading grade level. The average quality score for our website hits was low, and the average reading grade level was far above the recommended level. Academic websites offered significantly higher quality information, whereas commercial websites offered significantly lower quality information. The use of more complex search terms yielded information of higher reading grade level but not higher quality. Current internet information regarding clavicle fractures is of low quality and low readability. Higher quality information utilizing more accessible language on clavicle fractures is needed on the internet. It is important to be aware of the information accessible to patients prior to their presentation to our clinics. Patients should be advised to visit websites with academic affiliations and to avoid commercial websites. Copyright © 2015 The Japanese Orthopaedic Association. Published by Elsevier B.V.

The European Union considers diseases to be rare when they affect less than 5 in 10,000 people. It is estimated that there are between 5000 and 8000 different rare diseases. Consistent with this diversity, the quality of information available on the Web varies considerably. Thus, quality criteria for websites about rare diseases are needed. The objective of this study was to generate a catalog of quality criteria suitable for rare diseases. First, relevant certificates and quality recommendations for health information websites were identified through a comprehensive Web search. Second, all considered quality criteria of each certification program and catalog were examined, extracted into an overview table, and analyzed by thematic content. Finally, an interdisciplinary expert group verified the relevant quality criteria. We identified 9 quality certificates and criteria catalogs for health information websites with 304 single criteria items. Through this, we aggregated 163 various quality criteria, each assigned to one of the following categories: thematic, technical, service, content, and legal. Finally, a consensus about 13 quality criteria for websites offering medical information on rare diseases was determined. Of these categories, 4 (data protection concept, imprint, creation and updating date, and possibility to contact the website provider) were identified as being the most important for publishing medical information about rare diseases. The large number of different quality criteria appearing within a relatively small number of criteria catalogs shows that the opinion of what is important in the quality of health information differs. In addition, to define useful quality criteria for websites about rare diseases, which are an essential source of information for many patients, a trade-off is necessary between the high standard of quality criteria for health information websites in general and the limited provision of information about some rare diseases

Where is information quality lost at clinical level? A mixed-method study on information systems and data quality in three urban Kenyan ANC clinics

2013-01-01

Background Well-working health information systems are considered vital with the quality of health data ranked of highest importance for decision making at patient care and policy levels. In particular, health facilities play an important role, since they are not only the entry point for the national health information system but also use health data (and primarily) for patient care. Design A multiple case study was carried out between March and August 2012 at the antenatal care (ANC) clinics of two private and one public Kenyan hospital to describe clinical information systems and assess the quality of information. The following methods were developed and employed in an iterative process: workplace walkthroughs, structured and in-depth interviews with staff members, and a quantitative assessment of data quality (completeness and accurate transmission of clinical information and reports in ANC). Views of staff and management on the quality of employed information systems, data quality, and influencing factors were captured qualitatively. Results Staff rated the quality of information higher in the private hospitals employing computers than in the public hospital which relies on paper forms. Several potential threats to data quality were reported. Limitations in data quality were common at all study sites including wrong test results, missing registers, and inconsistencies in reports. Feedback was seldom on content or quality of reports and usage of data beyond individual patient care was low. Conclusions We argue that the limited data quality has to be seen in the broader perspective of the information systems in which it is produced and used. The combination of different methods has proven to be useful for this. To improve the effectiveness and capabilities of these systems, combined measures are needed which include technical and organizational aspects (e.g. regular feedback to health workers) and individual skills and motivation.

Kirby, Paige L; Reynolds, Kristin A; Walker, John R; Furer, Patricia; Pryor, Teaghan A M

2018-06-22

The Internet is an easily accessible source of information for women experiencing anxiety in pregnancy and/or postpartum to use when seeking health information. However, the Internet has several drawbacks, including inaccurate content that may be perceived as being accurate, non-biased, and evidence-based. Prior research indicates that anxiety and postpartum mental health websites have poor quality in terms of describing treatment options. There is a lack of research and knowledge in the area of perinatal anxiety, and an absence of research evaluating perinatal anxiety websites. The purpose of this study was to evaluate the quality of information regarding perinatal anxiety available on the Internet. Websites concerning perinatal anxiety were selected using the Google search engine. Each website was evaluated based on quality of health information, website usability, and readability. The 20 websites included in this study had low to moderate quality scores based on the DISCERN tool. There were no associations found between website order and website quality, or between website readability and website quality. Many websites had high PEMAT scores for the understandability section, which included content, style, and layout of information; however, most did not use visual aids to enhance comprehension. Most websites had low actionability scores, suggesting that information may not be useful in describing what actions may be taken to manage perinatal anxiety. This study highlights the need for high-quality websites concerning perinatal anxiety that are easy to navigate and provide the public with evidence-based information.

Review Of Internet Health Information Quality Initiatives

Background The massive growth of health information on the Internet; the global nature of the Internet; the seismic shift taking place in the relationships of various actors in this arena, and the absence of real protection from harm for citizens who use the Internet for health purposes are seen to be real problems. One response to many of these problems has been the burgeoning output of codes of conduct by numerous organizations trying to address quality of health information. Objectives Review the major self-regulatory initiatives in the English-speaking world to develop quality and ethical standards for health information on the Internet. Compare and analyze the approaches taken by the different initiatives. Clarify the issues around the development and enforcement of standards. Methods Quality initiatives selected meet one or more of the following criteria: Self-regulatory. A reasonable constituency. Diversity (eg, of philosophy, approach and process)-to achieve balance and wide representation, and to illustrate and compare different approaches. Historic value. A wider reach than a national audience, except when its reach is a significant sector of the Internet health information industry. The initiatives were compared in 3 ways: (1) Analysis and comparison of: key concepts, mechanism, or approach. Analysis of: the obligations that a provider has to meet to comply with the given initiative, the intended beneficiaries of that initiative, and the burdens imposed on different actors. These burdens are described in terms of their effect on the long-term sustainability and maintenance of the initiative by its developers. Analysis of the enforcement mechanisms. (2) Analysis and comparison by type of sponsoring organization, the reach of the initiative, and the sources of funding of the initiative or the sponsoring organization. (3) How the various initiatives fall under 1 of 3 key mechanisms and comparison of the advantages and disadvantages of these key mechanisms

Quality evaluation of JAMA Patient Pages on diabetes using the Ensuring Quality Information for Patient (EQIP) tool.

Many medical journals provide patient information leaflets on the correct use of medicines and/or appropriate lifestyles. Only a few studies have assessed the quality of this patient-specific literature. The purpose of this study was to evaluate the quality of JAMA Patient Pages on diabetes using the Ensuring Quality Information for Patient (EQIP) tool. A multidisciplinary group of 10 medical doctors analyzed all diabetes-related Patient Pages published by JAMA from 1998 to 2010 using the EQIP tool. Inter-rater reliability was assessed using the percentage of observed total agreement (p(o)). A quality score between 0 and 1 (the higher score indicating higher quality) was calculated for each item on every page as a function of raters' answers to the EQIP checklist. A mean score per item and a mean score per page were then calculated. We found 8 Patient Pages on diabetes on the JAMA web site. The overall quality score of the documents ranged between 0.55 (Managing Diabetes and Diabetes) and 0.67 (weight and diabetes). p(o) was at least moderate (>50%) for 15 of the 20 EQIP items. Despite generally favorable quality scores, some items received low scores. The worst scores were for the item assessing provision of an empty space to customize information for individual patients (score=0.01, p(o)=95%) and patients involvement in document drafting (score=0.11, p(o)=79%). The Patient Pages on diabetes published by JAMA were found to present weak points that limit their overall quality and may jeopardize their efficacy. We therefore recommend that authors and publishers of written patient information comply with published quality criteria. Further research is needed to evaluate the quality and efficacy of existing written health care information. Copyright © 2011 Primary Care Diabetes Europe. Published by Elsevier Ltd.

High-quality Health Information Provision for Stroke Patients.

PubMed

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

2016-09-05

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

Information Architecture for Quality Management Support in Hospitals.

PubMed

Rocha, Álvaro; Freixo, Jorge

2015-10-01

Quality Management occupies a strategic role in organizations, and the adoption of computer tools within an aligned information architecture facilitates the challenge of making more with less, promoting the development of a competitive edge and sustainability. A formal Information Architecture (IA) lends organizations an enhanced knowledge but, above all, favours management. This simplifies the reinvention of processes, the reformulation of procedures, bridging and the cooperation amongst the multiple actors of an organization. In the present investigation work we planned the IA for the Quality Management System (QMS) of a Hospital, which allowed us to develop and implement the QUALITUS (QUALITUS, name of the computer application developed to support Quality Management in a Hospital Unit) computer application. This solution translated itself in significant gains for the Hospital Unit under study, accelerating the quality management process and reducing the tasks, the number of documents, the information to be filled in and information errors, amongst others.

Quality of drug information on the World Wide Web and strategies to improve pages with poor information quality. An intervention study on pages about sildenafil.

Martin-Facklam, Meret; Kostrzewa, Michael; Martin, Peter; Haefeli, Walter E

2004-01-01

The generally poor quality of health information on the world wide web (WWW) has caused preventable adverse outcomes. Quality management of information on the internet is therefore critical given its widespread use. In order to develop strategies for the safe use of drugs, we scored general and content quality of pages about sildenafil and performed an intervention to improve their quality. The internet was searched with Yahoo and AltaVista for pages about sildenafil and 303 pages were included. For assessment of content quality a score based on accuracy and completeness of essential drug information was assigned. For assessment of general quality, four criteria were evaluated and their association with high content quality was determined by multivariate logistic regression analysis. The pages were randomly allocated to either control or intervention group. Evaluation took place before, as well as 7 and 22 weeks after an intervention which consisted of two letters with individualized feedback information on the respective page which were sent electronically to the address mentioned on the page. Providing references to scientific publications or prescribing information was significantly associated with high content quality (odds ratio: 8.2, 95% CI 3.2, 20.5).

Aims The generally poor quality of health information on the world wide web (WWW) has caused preventable adverse outcomes. Quality management of information on the internet is therefore critical given its widespread use. In order to develop strategies for the safe use of drugs, we scored general and content quality of pages about sildenafil and performed an intervention to improve their quality. Methods The internet was searched with Yahoo and AltaVista for pages about sildenafil and 303 pages were included. For assessment of content quality a score based on accuracy and completeness of essential drug information was assigned. For assessment of general quality, four criteria were evaluated and their association with high content quality was determined by multivariate logistic regression analysis. The pages were randomly allocated to either control or intervention group. Evaluation took place before, as well as 7 and 22 weeks after an intervention which consisted of two letters with individualized feedback information on the respective page which were sent electronically to the address mentioned on the page. Results Providing references to scientific publications or prescribing information was significantly associated with high content quality (odds ratio: 8.2, 95% CI 3.2, 20.5). The intervention had no influence on general or content quality. Conclusions To prevent adverse outcomes caused by misinformation on the WWW individualized feedback to the address mentioned on the page was ineffective. It is currently probably the most straight-forward approach to inform lay persons about indicators of high information quality, i.e. the provision of references. PMID:14678344

Background The European Union considers diseases to be rare when they affect less than 5 in 10,000 people. It is estimated that there are between 5000 and 8000 different rare diseases. Consistent with this diversity, the quality of information available on the Web varies considerably. Thus, quality criteria for websites about rare diseases are needed. Objective The objective of this study was to generate a catalog of quality criteria suitable for rare diseases. Methods First, relevant certificates and quality recommendations for health information websites were identified through a comprehensive Web search. Second, all considered quality criteria of each certification program and catalog were examined, extracted into an overview table, and analyzed by thematic content. Finally, an interdisciplinary expert group verified the relevant quality criteria. Results We identified 9 quality certificates and criteria catalogs for health information websites with 304 single criteria items. Through this, we aggregated 163 various quality criteria, each assigned to one of the following categories: thematic, technical, service, content, and legal. Finally, a consensus about 13 quality criteria for websites offering medical information on rare diseases was determined. Of these categories, 4 (data protection concept, imprint, creation and updating date, and possibility to contact the website provider) were identified as being the most important for publishing medical information about rare diseases. Conclusions The large number of different quality criteria appearing within a relatively small number of criteria catalogs shows that the opinion of what is important in the quality of health information differs. In addition, to define useful quality criteria for websites about rare diseases, which are an essential source of information for many patients, a trade-off is necessary between the high standard of quality criteria for health information websites in general and the limited

A central information portal on rare diseases (ZIPSE) has been conceptualized and implemented that allows patients, relatives and health care professionals to access quality-assured information. For this purpose, quality criteria have been developed specifically for rare diseases. At the same time, the information basis should take into account the specific needs of those interested. The needs of patients and relatives regarding online-based information are analyzed. Based on this, we examined to what extent the information basis, which is available according to the ZIPSE quality criteria, can cover these needs. If necessary, measures have to be developed to ensure quality- as well as needs-oriented information management. Qualitative interviews with patients and relatives were conducted, which were then evaluated using content analysis. Subsequently, a quantitative evaluation of the information on rare diseases in the portal was made. The research addresses how many websites do not fulfil the quality criteria, from which group of provider these websites originate and which criteria are not fulfilled. This is followed by a comparison of the quantitative and qualitative results. When looking for information on the Internet, the websites of self-help groups represent a significant source. These are perceived as very trustworthy and in the later course of the disease, offer detailed information on important information areas. Information websites from self-help groups, however, often do not meet quality requirements. Therefore, a transparent representation is made regarding the quality of the ZIPSE information pages. Pages that are not quality-assured can be actively requested, but will be clearly identified.

The quality of mental disorder information websites: a review.

PubMed

Reavley, Nicola J; Jorm, Anthony F

2011-11-01

This paper reviews studies assessing the quality of websites providing information about mental disorders. The review included 31 articles identified by searching research databases in March 2010. Topics covered included affective disorders, anxiety disorders, eating disorders, substance use disorders and schizophrenia/psychosis. The largest number of articles (13) reported studies assessing affective disorder information quality. Methodologies varied in site selection and rating methods, with some of limited validity. Most concluded that quality was poor, although quality of affective disorder sites may be improving. There is currently very little understanding of the influence of website quality on user behaviour. Future quality assessments might use the criteria informed by key behaviour change theories. A possible approach to research on websites and user behaviour might be to develop an evaluation framework incorporating strategies from behaviour change models, key mental health literacy elements and health outcomes relevant to mental health promotion.

The quality case for information technology in healthcare

PubMed Central

Bates, David W

2002-01-01

Background As described in the Institute of Medicine's Crossing the Quality Chasm report, the quality of health care in the U.S. today leaves much to be desired. Discussion One major opportunity for improving quality relates to increasing the use of information technology, or IT. Health care organizations currently invest less in IT than in any other information-intensive industry, and not surprisingly current systems are relatively primitive, compared with industries such as banking or aviation. Nonetheless, a number of organizations have demonstrated that quality can be substantially improved in a variety of ways if IT use is increased in ways that improve care. Specifically, computerization of processes that are error-prone and computerized decision support may substantially improve both efficiency and quality, as well as dramatically facilitate quality measurement. This report discusses the current levels of IT and quality in health care, how quality improvement and management are currently done, the evidence that more IT might be helpful, a vision of the future, and the barriers to getting there. Summary This report suggests that there are five key policy domains that need to be addressed: standards, incentives, security and confidentiality, professional involvement, and research, with financial incentives representing the single most important lever.

The Internet has become a ubiquitous source of medical information for both the patient and the physician. However, the quality of this information is highly variable. We evaluated the quality of Internet information available for femoroacetabular impingement (FAI). Four popular search engines were used to collect 100 Web sites containing information on FAI. Web sites were evaluated based on authorship, various content criteria, and the presence of Health On the Net Code of Conduct (HONcode) certification. By use of a novel evaluation system for quality, Web sites were also classified as excellent, high, moderate, poor, or inadequate and were subsequently analyzed. Web sites were evaluated as a group, followed by authorship type, by HONcode certification, and by quality level. Of the Web sites, 73 offered the ability to contact the author, 91 offered a considerable explanation of FAI, 54 provided surgical treatment options, 58 offered nonsurgical treatment options, 27 discussed possible complications, 11 discussed eligibility criteria, 31 discussed rehabilitation, 67 discussed a differential diagnosis, and 48 included peer-reviewed citations. We categorized 40 Web sites as academic, 33 as private, 9 as industry, 9 as public education, and 9 as blogs. Our novel quality evaluation system classified 16 Web sites as excellent, 18 as high, 17 as moderate, 18 as poor, and 31 as inadequate. Only 8% of all evaluated Web sites contained HONcode certification. We found that the quality of information available on the Internet about FAI was dramatically variable. A significantly large proportion of Web sites were from academic sources, but this did not necessarily indicate higher quality. Sites with HONcode certification showed as much variability in quality as noncertified sites. This study increases clinician competence in the available Internet information about FAI and helps them to confidently guide patients to formulate appropriate medical decisions based on high-quality

Health-care quality and information failure: Evidence from Nigeria.

PubMed

Evans, David K; Welander Tärneberg, Anna

2018-03-01

Low-quality health services are a problem across low- and middle-income countries. Information failure may contribute, as patients may have insufficient knowledge to discern the quality of health services. That decreases the likelihood that patients will sort into higher quality facilities, increasing demand for better health services. This paper presents results from a health survey in Nigeria to investigate whether patients can evaluate health service quality effectively. Specifically, this paper demonstrates that although more than 90% of patients agree with any positive statement about the quality of their local health services, satisfaction is significantly associated with the diagnostic ability of health workers at the facility. Satisfaction is not associated with more superficial characteristics such as infrastructure quality or prescriptions of medicines. This suggests that patients may have sufficient information to discern some of the most important elements of quality, but that alternative measures are crucial for gauging the overall quality of care.

Comparing the information conveyed by envelope modulation for speech intelligibility, speech quality, and music quality.

PubMed

Kates, James M; Arehart, Kathryn H

2015-10-01

This paper uses mutual information to quantify the relationship between envelope modulation fidelity and perceptual responses. Data from several previous experiments that measured speech intelligibility, speech quality, and music quality are evaluated for normal-hearing and hearing-impaired listeners. A model of the auditory periphery is used to generate envelope signals, and envelope modulation fidelity is calculated using the normalized cross-covariance of the degraded signal envelope with that of a reference signal. Two procedures are used to describe the envelope modulation: (1) modulation within each auditory frequency band and (2) spectro-temporal processing that analyzes the modulation of spectral ripple components fit to successive short-time spectra. The results indicate that low modulation rates provide the highest information for intelligibility, while high modulation rates provide the highest information for speech and music quality. The low-to-mid auditory frequencies are most important for intelligibility, while mid frequencies are most important for speech quality and high frequencies are most important for music quality. Differences between the spectral ripple components used for the spectro-temporal analysis were not significant in five of the six experimental conditions evaluated. The results indicate that different modulation-rate and auditory-frequency weights may be appropriate for indices designed to predict different types of perceptual relationships.

To assess the quality of the information that patients receive in the informed consent document signed prior to surgery. Cross-sectional study of a sample of cancer patients admitted for surgery at the University Hospital San Cecilio of Granada in 2011. After checking the inclusion criteria and obtaining their consent, demographic data were collected and procedure data, and a questionnaire «ad hoc» to assess the quality and comprehensiveness of the information provided in the informed consent. 150 patients were studied. The majority (109 over 150) said they had received sufficient information, in appropriate language, and had the opportunity to ask questions, but only 44.7% correctly answered three or more issues related to anesthesia. University education level, knowledge of the intervention, information about the anesthesia problems and appropriate language were associated. Although systematic informed consent was performed, half of the patients did not comprehend the anesthesia risks. Variables primarily related to the information received were associated with the quality of the response, but not with patient characteristics. Copyright © 2013 AEC. Published by Elsevier Espana.

2017-08-14

Little is known about the quality and readability of treatment information in specific neurogenic disorders, such as aphasia. The purpose of this study was to assess quality and readability of English-language Internet information available for aphasia treatment. Forty-three aphasia treatment websites were aggregated using five different country-specific search engines. Websites were then analysed using quality and readability assessments. Statistical calculations were employed to examine website ratings, differences between website origin and quality and readability scores, and correlations between readability instruments. Websites exhibited low quality with few websites obtaining Health On the Net (HON) certification or clear, thorough information as measured by the DISCERN. Regardless of website origin, readability scores were also poor. Approximate educational levels required to comprehend information on aphasia treatment websites ranged from 13 to 16 years of education. Significant differences were found between website origin and readability measures with higher levels of education required to understand information on websites of non-profit organisations. Current aphasia treatment websites were found to exhibit low levels of quality and readability, creating potential accessibility problems for people with aphasia and significant others. Websites including treatment information for aphasia must be improved in order to increase greater information accessibility.

Quality and Health Literacy Demand of Online Heart Failure Information.

The ubiquity of the Internet is changing the way people obtain their health information. Although there is an abundance of heart failure information online, the quality and health literacy demand of these information are still unknown. The purpose of this study is to evaluate the quality and health literacy demand (readability, understandability, and actionability) of the heart failure information found online. Google, Yahoo, Bing, Ask.com, and DuckDuckGo were searched for relevant heart failure Web sites. Two independent raters then assessed the quality and health literacy demand of the included Web sites. The quality of the heart failure information was assessed using the DISCERN instrument. Readability was assessed using 7 established readability tests. Finally, understandability and actionability were assessed using the Patient Education Materials Assessment Tool for Print Materials. A total of 46 Web sites were included in this analysis. The overall mean quality rating was 46.0 ± 8.9 and the mean readability score was 12.6 grade reading level. The overall mean understandability score was 56.3% ± 16.2%. Finally, the overall mean actionability score was 34.7% ± 28.7%. The heart failure information found online was of fair quality but required a relatively high health literacy level. Web content authors need to consider not just the quality but also the health literacy demand of the information found in their Web sites. This is especially important considering that low health literacy is likely prevalent among the usual audience.

Hospitals have been slow to adopt information technology (IT) largely because of a lack of generalizable evidence of the value associated with such adoption. To explore the relationship between IT adoption and quality of care in acute-care hospitals. Primary data on hospital IT adoption were combined with secondary hospital discharge data. Regression analyses were used to examine the relationship between various measures of IT adoption and several quality indicators after controlling for confounders. Adoption of IT was measured using a previously validated method that considers clinical, administrative, and strategic IT capabilities of acute-care hospitals. Quality measures included the Inpatient Quality Indicators developed by the Agency for Healthcare Research and Quality. Data from 98 hospitals were available for analyses. Hospitals adopted an average of 11.3 (45.2%) clinical IT applications, 15.7 (74.8%) administrative IT applications, and 5 (50%) strategic IT applications. In multivariate regression analyses, hospitals that adopted a greater number of IT applications were significantly more likely to have desirable quality outcomes on seven Inpatient Quality Indicator measures, including risk-adjusted mortality from percutaneous transluminal coronary angioplasty, gastrointestinal hemorrhage, and acute myocardial infarction. An increase in clinical IT applications was also inversely correlated with utilization of incidental appendectomy, and an increase in the adoption of strategic IT applications was inversely correlated with risk-adjusted mortality from craniotomy and laparoscopic cholecystectomy. Hospital adoption of IT is associated with desirable quality outcomes across hospitals in Florida. These findings will assist hospital leaders interested in understanding better the effect of costly IT adoption on quality of care in their institutions.

Information quality measurement of medical encoding support based on usability.

2013-12-01

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

2017-09-01

The internet is a major source for health information. An increasing number of people, including patients with insomnia, search for remedies online; however, little is known about the quality of such information. This study aimed to evaluate the quality and readability of insomnia-related online information. Google was used as the search engine, and the top websites on insomnia that met the inclusion criteria were evaluated for quality and readability. The analyzed websites belonged to nonprofit, commercial, or academic organizations and institutions such as hospitals and universities. Insomnia-related websites typically included definitions (85%), causes and risk factors (100%), symptoms (95%), and treatment options (90%). Cognitive behavioral therapy for insomnia (CBT-I) was the most commonly recommended approach for insomnia treatment, and sleep drugs are frequently mentioned. The overall quality of the websites on insomnia is moderate, but all the content exceeded the recommended reading ease levels. Concerns that must be addressed to increase the quality and trustworthiness of online health information include sharing metadata, such as authorship, time of creation and last update, and conflicts of interest; providing evidence for reliability; and increasing the readability for a layman audience.

We conducted a study to examine the quality and stability of information available from the Internet on four anaesthesia-related topics. In January 2006, we searched using four key words (porphyria, scleroderma, transfusion risk, and epidural analgesia risk) with five search engines (Google, HotBot, AltaVista, Excite, and Yahoo). We used a published scoring system (NetScoring) to evaluate the first 15 sites identified by each of these 20 searches. We also used a simple four-point scale to assess the first 100 sites in the Google search on one of our four topics ('epidural analgesia risk'). In November 2006, we conducted a second evaluation, using three search engines (Google, AltaVista, and Yahoo) with 14 synonyms for 'epidural analgesia risk'. The five search engines performed similarly. NetScoring scores were lower for transfusion risk (P < 0.001). One or more high-quality sites was identified consistently among the first 15 sites in each search. Quality scored using the simple scale correlated closely with medical content and design by NetScoring and with the number of references (P < 0.05). Synonyms of 'epidural analgesia risk' yielded similar results. The quality of accessed information improved somewhat over the 11 month period with Yahoo and AltaVista, but declined with Google. The Internet is a valuable tool for obtaining medical information, but the quality of websites varies between different topics. A simple rating scale may facilitate the quality scoring on individual websites. Differences in precise search terms used for a given topic did not appear to affect the quality of the information obtained.

Information systems as a quality management tool in clinical laboratories

Schmitz, Vanessa; Rosecler Bez el Boukhari, Marta

2007-11-01

This article describes information systems as a quality management tool in clinical laboratories. The quality of laboratory analyses is of fundamental importance for health professionals in aiding appropriate diagnosis and treatment. Information systems allow the automation of internal quality management processes, using standard sample tests, Levey-Jennings charts and Westgard multirule analysis. This simplifies evaluation and interpretation of quality tests and reduces the possibility of human error. This study proposes the development of an information system with appropriate functions and costs for the automation of internal quality control in small and medium-sized clinical laboratories. To this end, it evaluates the functions and usability of two commercial software products designed for this purpose, identifying the positive features of each, so that these can be taken into account during the development of the proposed system.

To assess information regarding radiology practices on public transparency Web sites. Eight Web sites comparing radiology centers' price and quality were identified. Web site content was assessed. Six of eight Web sites reported examination prices. Other reported information included hours of operation (4/8), patient satisfaction (2/8), American College of Radiology (ACR) accreditation (3/8), on-site radiologists (2/8), as well as parking, accessibility, waiting area amenities, same/next-day reports, mammography follow-up rates, examination appropriateness, radiation dose, fellowship-trained radiologists, and advanced technologies (1/8 each). Transparency Web sites had a preponderance of price (and to a lesser extent service quality) information, risking fostering price-based competition at the expense of clinical quality.

nowadays, the Internet is increasingly used by providers as a source of information for eating disorder health issues. However, health information on the Internet remains unregulated and varies in quality, accuracy and readability. the objective of this study was to determine both general and information quality of eating disorder websites, including obesity websites. three key terms (obesity, anorexia and bulimia) were entered into the Google search engine. Websites were assessed using two tests (HonCode certification and Bermudez-Tamayo et al. test) to analyze overall quality, and a third test (DISCERN test) to analyze specifically information quality. there were no significant differences regarding overall quality among the different pathologies studied (p = 0.197), although anorexia websites tended to obtain lower quality scores. Furthermore, all evaluated websites showed significant deficiencies regarding information quality (p = 0.032). Nevertheless, obesity websites showed a significant higher information quality than anorexia websites. the overall quality of eating disorders websites is moderate, but the information quality that they contain is fairly poor. Remarkably, anorexia nervosa websites showed both the lower information and general quality, while bulimia websites showed a higher general quality and obesity websites presented the most reliable information.

A Transparent and Transferable Framework for Tracking Quality Information in Large Datasets

Smith, Derek E.; Metzger, Stefan; Taylor, Jeffrey R.

The ability to evaluate the validity of data is essential to any investigation, and manual “eyes on” assessments of data quality have dominated in the past. Yet, as the size of collected data continues to increase, so does the effort required to assess their quality. This challenge is of particular concern for networks that automate their data collection, and has resulted in the automation of many quality assurance and quality control analyses. Unfortunately, the interpretation of the resulting data quality flags can become quite challenging with large data sets. We have developed a framework to summarize data quality information and facilitate interpretation by the user. Our framework consists of first compiling data quality information and then presenting it through 2 separate mechanisms; a quality report and a quality summary. The quality report presents the results of specific quality analyses as they relate to individual observations, while the quality summary takes a spatial or temporal aggregate of each quality analysis and provides a summary of the results. Included in the quality summary is a final quality flag, which further condenses data quality information to assess whether a data product is valid or not. This framework has the added flexibility to allow “eyes on” information on data quality to be incorporated for many data types. Furthermore, this framework can aid problem tracking and resolution, should sensor or system malfunctions arise. PMID:25379884

An Informatics Blueprint for Healthcare Quality Information Systems

Niland, Joyce C.; Rouse, Layla; Stahl, Douglas C.

2006-01-01

There is a critical gap in our nation's ability to accurately measure and manage the quality of medical care. A robust healthcare quality information system (HQIS) has the potential to address this deficiency through the capture, codification, and analysis of information about patient treatments and related outcomes. Because non-technical issues often present the greatest challenges, this paper provides an overview of these socio-technical issues in building a successful HQIS, including the human, organizational, and knowledge management (KM) perspectives. Through an extensive literature review and direct experience in building a practical HQIS (the National Comprehensive Cancer Network Outcomes Research Database system), we have formulated an “informatics blueprint” to guide the development of such systems. While the blueprint was developed to facilitate healthcare quality information collection, management, analysis, and reporting, the concepts and advice provided may be extensible to the development of other types of clinical research information systems.

Therefore, because of the importance of information quality attribute required by SMEs, the research aims to analyses the information quality required by SMEs to clarify the information quality into the dimension of information quality. The research was started by distributing online questionnaire to SMEs. The questionnaire result showed that the content dimension is the most aspect required by SMEs, followed by time and form dimension, respectively. Quality information attribute required by SMEs from a research is that the result may be applied to the business.

Rehabilitation consumers' use and understanding of quality information: a health literacy perspective.

To explore consumers' use and understanding of quality information about postacute rehabilitation facilities. Thematic, semistructured interviews. Two skilled nursing facilities and 2 inpatient rehabilitation facilities in a large Midwestern city. Rehabilitation inpatients (n=17) with stroke, hip fractures, and joint replacements and care partners (n=12) of rehabilitation inpatients. None. None. Health literacy imposed barriers to participants' understanding of quality information. Using the Institute of Medicine's Health Literacy Framework, we identified specific barriers that limited participants' abilities to (1) obtain quality information, (2) process and understand quality information, and (3) make appropriate decisions about the quality of a rehabilitation facility. Participants tended to rely on informal and nonquality information when choosing a rehabilitation facility. Given the barriers imposed by low health literacy, rehabilitation providers have a responsibility to present quality information in a way that consumers, especially those with low health literacy, can use and understand.

Quality of online information on breast cancer treatment options.

PubMed

Arif, Nadia; Ghezzi, Pietro

2018-02-01

Offering breast cancer patients treatment choice has become a priority as the involvement of patients in the decision-making process is associated with improved physical and psychological outcomes. As the Internet is increasingly being used by patients as a source of medical information, it is important to evaluate the quality of information relating to breast cancer on the Internet. We analysed 200 websites returned by google.co.uk searching "breast cancer treatment options" in terms of their typology and treatment options described. These were related to standard measures of health information quality such as the JAMA score and the presence of quality certifications, as well as readability. We found that health portals were of higher quality whilst commercial and professional websites were of poorer quality in terms of JAMA criteria. Overall, readability was higher than previously reported for other conditions, and Google ranked websites with better readability higher. Most websites discussed surgical and medical treatments. Few websites, with a large proportion being of commercial typology, discussed complementary and alternative medicine. Google ranked professional websites low whilst websites from non-profit organizations were promoted in the ranking. Copyright © 2017 Elsevier Ltd. All rights reserved.

Water fluoridation and the quality of information available online.

Frangos, Zachary; Steffens, Maryke; Leask, Julie

2018-02-13

The Internet has transformed the way in which people approach their health care, with online resources becoming a primary source of health information. Little work has assessed the quality of online information regarding community water fluoridation. This study sought to assess the information available to individuals searching online for information, with emphasis on the credibility and quality of websites. We identified the top 10 web pages returned from different search engines, using common fluoridation search terms (identified in Google Trends). Web pages were scored using a credibility, quality and health literacy tool based on Global Advisory Committee on Vaccine Safety (GAVCS) and Center for Disease Control and Prevention (CDC) criteria. Scores were compared according to their fluoridation stance and domain type, then ranked by quality. The functionality of the scoring tool was analysed via a Bland-Altman plot of inter-rater reliability. Five-hundred web pages were returned, of which 55 were scored following removal of duplicates and irrelevant pages. Of these, 28 (51%) were pro-fluoridation, 16 (29%) were neutral and 11 (20%) were anti-fluoridation. Pro, neutral and anti-fluoridation pages scored well against health literacy standards (0.91, 0.90 and 0.81/1 respectively). Neutral and pro-fluoridation web pages showed strong credibility, with mean scores of 0.80 and 0.85 respectively, while anti-fluoridation scored 0.62/1. Most pages scored poorly for content quality, providing a moderate amount of superficial information. Those seeking online information regarding water fluoridation are faced with comprehensible, yet poorly referenced, superficial information. Sites were credible and user friendly; however, our results suggest that online resources need to focus on providing more transparent information with appropriate figures to consolidate the information. © 2018 FDI World Dental Federation.

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.

Incorporating Quality Control Information in the Sensor Web

Devaraju, Anusuriya; Kunkel, Ralf; Bogena, Heye

2013-04-01

The rapid development of sensing technologies had led to the creation of large amounts of heterogeneous environmental observations. The Sensor Web provides a wider access to sensors and observations via common protocols and specifications. Observations typically go through several levels of quality control, and aggregation before they are made available to end-users. Raw data are usually inspected, and related quality flags are assigned. Data are gap-filled, and errors are removed. New data series may also be derived from one or more corrected data sets. Until now, it is unclear how these kinds of information can be captured in the Sensor Web Enablement (SWE) framework. Apart from the quality measures (e.g., accuracy, precision, tolerance, or confidence), the levels of observational series, the changes applied, and the methods involved must be specified. It is important that this kind of quality control information is well described and communicated to end-users to allow for a better usage and interpretation of data products. In this paper, we describe how quality control information can be incorporated into the SWE framework. Concerning this, first, we introduce the TERENO (TERrestrial ENvironmental Observatories), an initiative funded by the large research infrastructure program of the Helmholtz Association in Germany. The main goal of the initiative is to facilitate the study of long-term effects of climate and land use changes. The TERENO Online Data RepOsitORry (TEODOOR) is a software infrastructure that supports acquisition, provision, and management of observations within TERENO via SWE specifications and several other OGC web services. Next, we specify changes made to the existing observational data model to incorporate quality control information. Here, we describe the underlying TERENO data policy in terms of provision and maintenance issues. We present data levels, and their implementation within TEODOOR. The data levels are adapted from those used by

The purpose of this study is to evaluate the readability and quality of English-language Internet information related to vocal hygiene, vocal health, and prevention of voice disorders. This study extends recent work because it evaluates readability, content quality, and website origin across broader search criteria than previous studies evaluating online voice material. Eighty-five websites were aggregated using five different country-specific search engines. Websites were then analyzed using quality and readability assessments. The entire web page was evaluated; however, no information or links beyond the first page was reviewed. Statistical calculations were employed to examine website ratings, differences between website origin and quality and readability scores, and correlations between readability instruments. Websites exhibited acceptable quality as measured by the DISCERN. However, only one website obtained the Health On the Net certification. Significant differences in quality were found among website origin, with government websites receiving higher quality ratings. Approximate educational levels required to comprehend information on the websites ranged from 8 to 9 years of education. Significant differences were found between website origin and readability measures with higher levels of education required to understand information on websites of nonprofit organizations. Current vocal hygiene, vocal health, and prevention of voice disorders websites were found to exhibit acceptable levels of quality and readability. However, highly rated Internet information related to voice care should be made more accessible to voice clients through Health On the Net certification. Published by Elsevier Inc.

Public reporting of cost and quality information in orthopaedics.

PubMed

Marjoua, Youssra; Butler, Craig A; Bozic, Kevin J

2012-04-01

Public reporting of patient health outcomes offers the potential to incentivize quality improvement by fostering increased accountability among providers. Voluntary reporting of risk-adjusted outcomes in cardiac surgery, for example, is viewed as a "watershed event" in healthcare accountability. However, public reporting of outcomes, cost, and quality information in orthopaedic surgery remains limited by comparison, attributable in part to the lack of standard assessment methods and metrics, provider fear of inadequate adjustment of health outcomes for patient characteristics (risk adjustment), and historically weak market demand for this type of information. We review the origins of public reporting of outcomes in surgical care, identify existing initiatives specific to orthopaedics, outline the challenges and opportunities, and propose recommendations for public reporting of orthopaedic outcomes. We performed a comprehensive review of the literature through a bibliographic search of MEDLINE and Google Scholar databases from January 1990 to December 2010 to identify articles related to public reporting of surgical outcomes. Orthopaedic-specific quality reporting efforts include the early FDA adverse event reporting MedWatch program and the involvement of surgeons in the Physician Quality Reporting Initiative. Issues that require more work include balancing different stakeholder perspectives on quality reporting measures and methods, defining accountability and attribution for outcomes, and appropriately risk-adjusting outcomes. Given the current limitations associated with public reporting of quality and cost in orthopaedic surgery, valuable contributions can be made in developing specialty-specific evidence-based performance measures. We believe through leadership and involvement in policy formulation and development, orthopaedic surgeons are best equipped to accurately and comprehensively inform the quality reporting process and its application to improve the

2018-05-01

The aim of this study was to assess the quality of patient information on bariatric surgery in the internet using the modified Ensuring Quality Information for Patients (EQIP) tool. Systematic review of information on bariatric surgery in the internet by entering common search terms into five search engines. The top 100 websites of every search term and search engine were assessed using the validated EQIP tool (maximum score, 36), which entails points for content, structure, and identification data of a given website. Websites at or above the 99th percentile were analyzed separately (n = 8). The median EQIP score of all included websites (n = 463) was 17 (IQR 15-19). While information on the medical problem, the indication for surgery, or the treatment alternatives was present in 84% of all websites, only 10% of the included websites contained adequate information on postoperative complications. Although quantitative information on incidence (37.5%) and treatment of complications (12.5%) was significantly better in the top 99th percentile websites, the content of relevant information such as occurrence and treatment of complications was still very limited. The overall quality of patient information on bariatric surgery in the internet is relatively poor. Especially incidence of complications and their treatment are rarely reported even on websites with a 99th percentile EQIP score.

Leveraging Health Information Technology to Improve Quality in Federal Healthcare.

Healthcare delivery in America is extremely complex because it is comprised of a fragmented and nonsystematic mix of stakeholders, components, and processes. Within the US healthcare structure, the federal healthcare system is poised to lead American medicine in leveraging health information technology to improve the quality of healthcare. We posit that through developing, adopting, and refining health information technology, the federal healthcare system has the potential to transform federal healthcare quality by managing the complexities associated with healthcare delivery. Although federal mandates have spurred the widespread use of electronic health records, other beneficial technologies have yet to be adopted in federal healthcare settings. The use of health information technology is fundamental in providing the highest quality, safest healthcare possible. In addition, health information technology is valuable in achieving the Agency for Healthcare Research and Quality's implementation goals. We conducted a comprehensive literature search using the Google Scholar, PubMed, and Cochrane databases to identify an initial list of articles. Through a thorough review of the titles and abstracts, we identified 42 articles as having relevance to health information technology and quality. Through our exclusion criteria of currency of the article, citation frequency, applicability to the federal health system, and quality of research supporting conclusions, we refined the list to 11 references from which we performed our analysis. The literature shows that the use of computerized physician order entry has significantly increased accurate medication dosage and decreased medication errors. The use of clinical decision support systems have significantly increased physician adherence to guidelines, although there is little evidence that indicates any significant correlation to patient outcomes. Research shows that interoperability and usability are continuing challenges for

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.

Multiple options are available for selection and purchase of apparel including in-store, catalogue, and Internet. The present purpose was to compare information about quality available to consumers in three retail formats. Students studying quality of apparel selected a product which could be purchased in each of the three formats, completed an evaluation from both a consumer's and preprofessional perspective, and made recommendations for improving information on quality. A total of 413 recommendations were categorized and tested for independence. Students had similar expectations for cues of quality across Internet, catalogue, and in-store formats including fiber content, country of origin, 3-dimensional information about fit, color accuracy, size charts, and strong customer service. Students expected a uniform array of information on quality regardless of the shopping format. Merchandisers must be aware of the total image across formats and be prepared to explore methods for improving communication of information on quality in each.

(a) To find out how much patient information material on display in family physicians' offices refers to management choices, and hence may be useful to support informed and shared decision-making (ISDM) by patients and (b) to evaluate the quality of print information materials exchanged during the consultation, i.e. brought in by patients or given out by family physicians. All print information available for patients and exchanged between physicians and patients was collected in a single complete day of the office practices of 21 family physicians. A published and validated instrument (DISCERN) was used to assess quality. Community office practices in the greater Vancouver area, British Columbia, Canada. The physicians were purposefully recruited by their association with the medical school Department of Family Practice, their interest in providing patients with print information and their representation of a range of practice types and location. The source of the pamphlets and these categories: available in the physicians' offices; exchanged between physician and patient; and produced with the explicit or apparent intent to support evidence-based patient choice. The quality of the print information to support ISDM, as measured by DISCERN and the ease of use and reliability of the DISCERN tool. Fewer than 50% of pamphlets available in these offices fulfilled our minimum criteria for ISDM (mentioned more than one management option). Offices varied widely in the proportion of pamphlets on display that supported ISDM and how particular the physician was in selecting materials. The DISCERN tool is quick, valid and reliable for the evaluation of patient information. The quality of patient information materials used in the consultation and available in these offices was below midpoint on the DISCERN score. Major deficiencies were with respect to the mention of choices, risks, effect of no treatment or uncertainty and reliability (source, evidence-base). Good quality

Information Quality as a Foundation for User Trustworthiness of Earth Science Data.

Information quality is multidimensional. Four different aspects of information quality can be defined based on the lifecycle stages of Earth Science data products: science, product, stewardship and services. With increasing requirements on ensuring and improving information quality coming from multiple government agencies and throughout industry, there have been considerable efforts toward improving information quality during the last decade, much of which has not been well vetted in a collective sense until recently. Given this rich background of prior work, the Information Quality Cluster (IQC), established within the Federation of Earth Science Information Partners (ESIP) in 2011, and reactivated in the summer of 2014, has been active with membership from multiple organizations. The IQC's objectives and activities, aimed at ensuring and improving information quality for Earth science data and products, are also considered vital toward improving the trustworthiness of Earth science data to a vast and interdisciplinary community of data users. During 2016, several members of the IQC have led the development and assessment of four use cases. This was followed up in 2017 with multiple panel sessions at the 2017 Winter and Summer ESIP Meetings to survey the challenges posed in the various aspects of information quality. What was discovered to be most lacking is the transparency of data lineage (i.e., provenance and maturity), uniform methods for uncertainty characterization, and uniform quality assurance data and metadata. While solutions to these types of issues exist, most data producers have little time to investigate and collaborate to arrive at and conform to a consensus approach. The IQC has positioned itself as a community platform to bring together all relevant stakeholders from data producers, repositories, program managers, and the end users. A combination of both well-vetted and "trailblazing" solutions are presented to address how data trustworthiness can

The objective of the study is to evaluate the quality of web-based information on social phobia and to investigate particular quality indicators. Two keywords, "Social phobia" and "Social Anxiety Disorder", were entered into five popular World Wide Web search engines. Websites were assessed with a standardized proforma designed to rate sites on the basis of accountability, presentation, interactivity, readability, and content quality. "Health On the Net" (HON) quality label and DISCERN scale scores aiding people without content expertise to assess quality of written health publication were used to verify their efficiency as quality indicators. This study evaluates the quality of web-based information on social phobia. On the 200 identified links, 58 were included. On the basis of outcome measures, the overall quality of the sites turned out to be poor. DISCERN and HON label were indicators of good quality indicators. Accountability criteria were poor indicators of site quality. Although social phobia education Websites for patients are common, educational material highly varies in quality and content. There is a need for better evidence-based information about social phobia on the Web and a need to reconsider the role of accountability criteria as indicators of site quality. Clinicians should advise patients of the HON label and DISCERN as useful indicators of site quality. (c) 2007 Wiley-Liss, Inc.

A quality-control Internet-based study using recognized quality-scoring systems. To evaluate the quality of information available on the Internet. Quality of health information on the Internet is of much concern and the emphasis for appraisal of Internet Web sites is needed. This study is to determine if it has improved with the surge in Internet usage. The 3 most commonly used search engines were identified and a search for "Discectomy" was performed on each. Two reviewers categorized the Web sites according to their types and the quality of each was assessed using recognized scoring systems including the Journal of the American Medical Association (JAMA) benchmark, DISCERN score, and discectomy-specific content score. The quality of the information was also assessed according to the presence and absence of the Health on the Net code. Fifty-three Web sites were identified, and analyzed. Commercial Web sites were predominant, 24 of them were identified, 7 were governmental, 6 were produced by physicians, none were produced by allied health professionals, 3 were academic, 4 were public health information Web sites, 4 were attached to social media and discussion groups, 3 were related to media, and 2 were unspecified. Internet sites with a Health on the Net code demonstrated significantly higher quality than those without the code (P < 0.0001). Public health information Web sites attained the highest overall DISCERN and discectomy-specific scores followed by Web sites of the government and nonprofit organizations. The overall quality of information regarding discectomy remains poor and variable despite an exponential increase in the number of users and Web sites, with a slight trend toward improvement, only 20% to 30% are of good quality, compared with that 10 years ago (<10%). Presence of Health on the Net code is a very reliable marker for health information quality.

This study evaluated the quality, reliability and readability of information on the Internet on adult orthodontics. A quality assessment of adult orthodontic websites. Postgraduate Orthodontic Unit, Cork University Dental School and Hospital, Cork, Ireland. An Internet search using three search engines (Google, Yahoo and Bing) was conducted using the terms ('adult orthodontics' and 'adult braces'). The first 50 websites from each engine and under each search term were screened and exclusion criteria applied. Included websites were then assessed for quality using four methods: the HON seal, JAMA benchmarks, the DISCERN instrument and the LIDA tool. Readability of included websites was assessed using the Flesch Reading Ease Score (FRES). Only 13 websites met the inclusion criteria. Most were of US origin (n = 8; 61%). The authors of the websites were dentists (n = 5; 39%), professional organizations (n = 2; 15%), past patients (n = 2; 15%) and unspecified (n = 4; 31%). Only 1 website displayed the HON seal and three websites contained all JAMA benchmarks. The mean overall score for DISCERN was 3.9/5 and the mean total LIDA score was 115/144. The average FRES score was 63.1/100. The number of informative websites on adult orthodontics is low and these are of moderate quality. More accurate, high-quality Internet resources are required on adult orthodontics. Recommendations are made as to how this may be achieved.

German dentists' websites on periodontitis have low quality of information.

2017-08-02

The internet is an increasingly relevant source of health information. We aimed to assess the quality of German dentists' websites on periodontitis, hypothesizing that it was significantly associated with a number of practice-specific parameters. We searched four electronic search engines and included pages which were freely accessible, posted by a dental practice in Germany, and mentioned periodontal disease/therapy. Websites were assessed for (1) technical and functional aspects, (2) generic quality and risk of bias, (3) disease-specific information. For 1 and 2, validated tools (LIDA/DISCERN) were used for assessment. For 3, we developed a criterion catalogue encompassing items on etiologic and prognostic factors for periodontitis, the diagnostic and treatment process, and the generic chance of tooth retention in periodontitis patients. Inter- and intra-rater reliabilities were largely moderate. Generalized linear modeling was used to assess the association between the information quality (measured as % of maximally available scores) and practice-specific characteristics. Seventy-one websites were included. Technical and functional aspects were reported in significantly higher quality (median: 71%, 25/75th percentiles: 67/79%) than all other aspects (p < 0.05). Generic risk of bias and most disease-specific aspects showed significantly lower reporting quality (median range was 0-40%), with poorest reporting for prognostic factors (9;0/27%), diagnostic process (0;0/33%) and chances of tooth retention (0;0/2%). We found none of the practice-specific parameters to have significant impact on the overall quality of the websites. Most German dentists' websites on periodontitis are not fully trustworthy and relevant information are not or insufficiently considered. There is great need to improve the information quality from such websites at least with regards to periodontitis.

Descriptive, cross-sectional analysis of websites with information on spinal cord injury (SCI) in Spanish. To assess the quality, readability and presence of quality labels on web pages with information about SCI in Spanish. The Internet. An Internet search was conducted on Google with the keywords 'lesión medular' (spinal cord injury), 'paraplejia' (paraplegia) and 'tetraplejia' (tetraplegia). The first 50 results of each search were included. The quality of websites was assessed with the LIDA tool while the readability was assessed with the Flesch-Szigriszt index and the INFLESZ scale. We also checked the presence of any quality label. After excluding duplicated and irrelevant results, 33 websites were analysed. Only four of them had a quality label. The mean score of the LIDA tool was 61.12% (medium quality), and the worst results were those referring to the reliability of the information. The readability of the web pages was somewhat difficult, with a mean of 48.22 in the Flesch-Szigriszt index. Only eight of the websites showed normal readability. We observed no differences in either the quality or the readability of the websites according to their origin or the presence of quality labels. The websites analysed present a medium quality. Mainly, they should improve the reliability of their contents and their readability, including more quality labels. For SCI information in Spanish to be understandable and to provide valuable content, websites analysed in our study need to improve the quality parameters.

The Internet provides a large source of health-related information for patients. However, information on the Internet is mostly unregulated, ranging from factually correct to misleading or contradictory information. The objective of this study was to determine the quality of information available on World Wide Web on the topic of bunions. Websites were identified using 3 search engines (Google, Yahoo, and MSN) and the search term bunions. The first 30 websites in each search were analyzed. Websites were assessed using the validated DISCERN rating instrument to determine the quality of health content and treatment information. The DISCERN tool possesses moderate to very good strength of interobserver agreement, ranging from .41 to .82. A total of 90 websites were assessed and studied. Forty-eight sites were duplicated, leaving 42 unique sites. Of these, 60% (25/42) provided patient-related information, 21% (9/42) were advertisements, 7% (3/42) promoted medical centers, 5% (2/42) were dead links, 5% (2/42) were news articles, and 2% (1/42) was doctor's information. In determining the quality of unique sites, of a maximum score of 5, the average overall DISCERN score was 2.9 (range, 1.8 to 4.6). Only 24% (10/42) of websites were classified as "good" or "excellent." Although most websites contained information on symptoms, causes, risk factors, investigations, and treatment options on bunions, 60% (25/42) did not provide adequate information on the benefits for each treatment, 45% (19/42) did not contain any risks of treatment, and 76% (32/42) did not describe how treatment choices affect overall quality of life. The sources of information were clear in 33% (14/42), and the date when this information was reviewed was given in only 50% (21/42). Only 29% (12/42) of websites had been updated within the past 2 years. Overall, the quality of patient information on bunions varies widely. We believe clinicians should guide patients in identifying the best possible and genuine

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

The Internet is a highly powerful resource for patients and provides an extensive amount of information on medical conditions. It is therefore important that the information accessible is accurate, up to date, and at an appropriate comprehensive level for the general public. This article aims to evaluate the quality of patient information on meningiomas. The term meningioma was searched using the following search engines: Google, Bing, Yahoo, Ask, and AOL. The top 100 meningioma Web sites were analyzed for readability using the Flesch Reading Ease score and the Flesch-Kincaid grade level. The quality of each Web page was assessed with the DISCERN instrument and the Centers for Disease Control and Prevention (CDC) Clear Communication Index (CCI). The quality of information on the Internet on meningiomas is highly variable. The overall mean Flesch Reading Ease score was 43.1 (standard deviation = 13.3) and the mean Flesch-Kincaid grade of all the Web sites was 11.2 (standard deviation = 2.3). This finding suggests that the information is on average difficult to read. Only one Web site was at the recommended seventh-grade level and the remainder were above this grade. Only one third of the Web pages had Health On the Net Code of Conduct or The Information Standard certification and were found to be significantly of higher quality: DISCERN (P = 0.022) and CDC CCI (P = 0.027). More than 50% of the Web sites had significantly poor or average DISCERN scores and only 2 Web sites fulfilled the CDC CCI criteria. It is recommended that clinicians personally research material for their patients to be able to guide them to reliable and accurate Web sites. It is also encouraged to become Health On the Net Code of Conduct/The Information Standard certified because this may indicate information of high quality. In addition, it is also recommended that authors of existing information assess the quality of their online health information against the CDC CCI criteria. Crown

The Internet is becoming an important source for medication information. Although the quality of consumer medication information (CMI) in brick and mortar pharmacies has been reported to be suboptimal, little is known about the quality of CMI offered by pharmacy Web sites. To evaluate the quality, readability, and provision of Web functionality of 4 popular medications (atenolol, nitroglycerin, atorvastatin, and glyburide) available on the websites of 3 of the largest retail pharmacies: Walgreens, CVS Pharmacy, and Rite Aid. The quality of online medication information was evaluated by 2 reviewers using a preexisting evaluation instrument created by a national panel of experts. Readability level was assessed using the Gunning Fog Test. We also assessed the presence of 4 Web-specific functional criteria: (1) capability for font enlargement, (2) availability of a glossary of terms, (3) presence of an "Ask a pharmacist" feature, and (4) access to detailed medication information or full prescribing information. Overall, medication information was 77% adherent to the criteria evaluated. When broken down by drug, CMI was most adherent for atorvastatin (83%), followed by glyburide (77%), atenolol (76%), and nitroglycerin (75%). The average readability level was found to be 10th grade. No pharmacy Web site provided the ability for font enlargement, a glossary of terms, or access to detailed medication information; however, all pharmacy Web sites provided an "Ask a pharmacist" service. Although pharmacy Web sites were found to have an overall good content quality, the high readability level of text, areas of incomplete information, and limited use of desirable Web functionality suggest room for improvement.

The Internet has become an important source of health-related information for consumers, among whom younger women constitute a notable group. The aims of this study were (1) to evaluate the quality and readability of online information about gynecologic cancer using validated instruments and (2) to relate the quality of information to its readability. Using the Alexa Rank, we obtained a list of 35 Web pages providing information about 7 gynecologic malignancies. These were assessed using the Health on the Net (HON) seal of approval, the Journal of the American Medical Association (JAMA) benchmarks, and the DISCERN instrument. Flesch readability score was calculated for sections related to symptoms and signs and treatment. Less than 30% of the Web pages displayed the HON seal or achieved all JAMA benchmarks. The majority of the treatment sections were of moderate to high quality according to the DISCERN. There was no significant relationship between the presence of the HON seal and readability. Web pages achieving all JAMA benchmarks were significantly more difficult to read and understand than Web pages that missed any of the JAMA benchmarks. Treatment-related content of moderate to high quality as assessed by the DISCERN had a significantly better readability score than the low-quality content. The online information about gynecologic cancer provided by the most frequently visited Web pages is of variable quality and in general difficult to read and understand. The relationship between the quality and readability remains unclear. Health care providers should direct their patients to reliable material online because patients consider the Internet as an important source of information.

A loss-of-separation (LOS) is said to occur when two aircraft are spatially too close to one another. A LOS is the fundamental unsafe event to be avoided in air traffic management and conflict detection (CD) is the function that attempts to predict these LOS events. In general, the effectiveness of conflict detection relates to the overall safety and performance of an air traffic management concept. An abstract, parametric analysis was conducted to investigate the impact of surveillance quality, level of intent information, and quality of intent information on conflict detection performance. The data collected in this analysis can be used to estimate the conflict detection performance under alternative future scenarios or alternative allocations of the conflict detection function, based on the quality of the surveillance and intent information under those conditions.Alternatively, this data could also be used to estimate the surveillance and intent information quality required to achieve some desired CD performance as part of the design of a new separation assurance system.

This research was conducted to identify both the users' service requirements on health information websites (HIWs) and the key functional elements for running HIWs. With the quality function deployment framework, the derived service attributes (SAs) are mapped into the suppliers' functional characteristics (FCs) to derive the most critical FCs for the users' satisfaction. Using the survey data from 228 respondents, the SAs, FCs and their relationships were analyzed using various multivariate statistical methods such as principal component factor analysis, discriminant analysis, correlation analysis, etc. Simple and compound FC priorities were derived by matrix calculation. Nine factors of SAs and five key features of FCs were identified, and these served as the basis for the house of quality model. Based on the compound FC priorities, the functional elements pertaining to security and privacy, and usage support should receive top priority in the course of enhancing HIWs. The quality function deployment framework can improve the FCs of the HIWs in an effective, structured manner, and it can also be utilized for critical success factors together with their strategic implications for enhancing the service quality of HIWs. Therefore, website managers could efficiently improve website operations by considering this study's results.

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

Objective To analyze the factors associated with employee awareness of employer-disseminated quality information on providers. Data Sources Primary data were collected in 2002 on a stratified, random sample of 1,365 employees in 16 firms that are members of the Buyers Health Care Action Group (BHCAG) located in the Minneapolis–St. Paul region. An employer survey was also conducted to assess how employers communicated the quality information to employees. Study Design In 2001, BHCAG sponsored two programs for reporting provider quality. We specify employee awareness of the quality information to depend on factors that influence the benefits and costs of search. Factors influencing the benefits include age, sex, provider satisfaction, health status, job tenure, and Twin Cities tenure. Factors influencing search costs include employee income, education, and employer communication strategies. We estimate the model using bivariate probit analysis. Data Collection Employee data were collected by phone survey. Principal Findings Overall, the level of quality information awareness is low. However, employer communication strategies such as distributing booklets to all employees or making them available on request have a large effect on the probability of quality information awareness. Employee education and utilization of providers' services are also positively related to awareness. Conclusions This study is one of the first to investigate employee awareness of provider quality information. Given the direct implications for medical outcomes, one might anticipate higher rates of awareness regarding provider quality, relative to plan quality. However, we do not find empirical evidence to support this assertion. PMID:15533188

Research has shown that up to 89% of parents used the Internet to seek health information regarding their child's medical condition. Much of the information on the Internet is valuable; however, the quality of health information is variable and unregulated. The aim of this study was to evaluate the quality and content of information about Perthes disease on the Internet using recognized scoring systems, identification of quality markers, and describe a novel specific score. We searched the top 3 search engines (Google, Yahoo!, and Bing) for the following keywords: "Perthes disease." Forty-five unique Web sites were identified. The Web sites were then categorized by type and assessed using the DISCERN score, the Journal of the American Medical Association (JAMA) benchmark criteria, and a novel Perthes-specific Content score. The presence of the Health On the Net (HON) code, a reported quality assurance marker, was noted. Of the Web sites analyzed, the Majority were Governmental and Nonprofit Organizations (NPO) (37.8%), followed by commercial Web sites (22.2%). Only 6 of the Web sites were HONcode certified. The mean DISCERN score was 53.1 (SD=9.0). The Governmental and NPO Web sites had the highest overall DISCERN scores followed closely by Physician Web sites. The mean JAMA benchmark criteria score was 2.1 (SD=1.2). Nine Web sites had maximal scores and the Academic Web sites had the highest overall JAMA benchmark scores. DISCERN scores, JAMA benchmark scores, and Perthes-specific Content scores were all greater for Web sites that bore the HONcode seal. The quality of information available online regarding Perthes disease is of variable quality. Governmental and NPO Web sites predominate and also provide higher quality content. The HONcode seal is a reliable indicator of Web site quality. Physicians should recommend the HONcode seal to their patients as a reliable indicator of Web site quality or, better yet, refer patients to sites they have personally reviewed

The availability and accessibility of remote sensing (RS) data, cloud processing platforms and provided information products and services has increased the size and diversity of the RS user community. This development also generates a need for validation approaches to assess data quality. Validation approaches employ quality criteria in their assessment. Data Quality (DQ) dimensions as the basis for quality criteria have been deeply investigated in the database area and in the remote sensing domain. Several standards exist within the RS domain but a general classification - established for databases - has been adapted only recently. For an easier identification of research opportunities, a better understanding is required how quality criteria are employed in the RS lifecycle. Therefore, this research investigates how quality criteria support decisions that guide the RS lifecycle and how they relate to the measured DQ dimensions. Subsequently follows an overview of the relevant standards in the RS domain that is matched to the RS lifecycle. Conclusively, the required research needs are identified that would enable a complete understanding of the interrelationships between the RS lifecycle, the data sources and the DQ dimensions, an understanding that would be very valuable for designing validation approaches in RS.

Belen Sağlam, Rahime; Taskaya Temizel, Tugba

2015-01-01

Objective: When searching for particular medical information on the internet the challenge lies in distinguishing the websites that are relevant to the topic, and contain accurate information. In this article, we propose a framework that automatically identifies and ranks diabetes websites according to their relevance and information quality based on the website content. Design: The proposed framework ranks diabetes websites according to their content quality, relevance and evidence based medicine. The framework combines information retrieval techniques with a lexical resource based on Sentiwordnet making it possible to work with biased and untrusted websites while, at the same time, ensuring the content relevance. Measurement: The evaluation measurements used were Pearson-correlation, true positives, false positives and accuracy. We tested the framework with a benchmark data set consisting of 55 websites with varying degrees of information quality problems. Results: The proposed framework gives good results that are comparable with the non-automated information quality measuring approaches in the literature. The correlation between the results of the proposed automated framework and ground-truth is 0.68 on an average with p < 0.001 which is greater than the other proposed automated methods in the literature (r score in average is 0.33).

Objectives (a) To find out how much patient information material on display in family physicians’ offices refers to management choices, and hence may be useful to support informed and shared decision‐making (ISDM) by patients and (b) to evaluate the quality of print information materials exchanged during the consultation, i.e. brought in by patients or given out by family physicians. Design All print information available for patients and exchanged between physicians and patients was collected in a single complete day of the office practices of 21 family physicians. A published and validated instrument (DISCERN) was used to assess quality. Setting and participants Community office practices in the greater Vancouver area, British Columbia, Canada. The physicians were purposefully recruited by their association with the medical school Department of Family Practice, their interest in providing patients with print information and their representation of a range of practice types and location. Main variables studied The source of the pamphlets and these categories: available in the physicians’ offices; exchanged between physician and patient; and produced with the explicit or apparent intent to support evidence‐based patient choice. Main outcome measures The quality of the print information to support ISDM, as measured by DISCERN and the ease of use and reliability of the DISCERN tool. Results and conclusions Fewer than 50% of pamphlets available in these offices fulfilled our minimum criteria for ISDM (mentioned more than one management option). Offices varied widely in the proportion of pamphlets on display that supported ISDM and how particular the physician was in selecting materials. The DISCERN tool is quick, valid and reliable for the evaluation of patient information. The quality of patient information materials used in the consultation and available in these offices was below midpoint on the DISCERN score. Major deficiencies were with

Ellsworth, Bridget; Patel, Hiren; Kamath, Atul F

2016-10-01

The purpose of this study was to assess the quality of information available to patients on the Internet when using popular search engines to search the term "hip arthroscopy." We analyzed the quality and content of information about hip arthroscopy (HA) on the first 50 websites returned by the search engines Google and Bing for the search term "hip arthroscopy." The sites were categorized by type, and quality and content were measured using the DISCERN score, along with an HA-specific content score. The HA-specific content score was used to assess each website for the presence or absence of 19 topics about HA determined to be important for a patient seeking information about the procedure. The Health on the Net Code (HONcode) status of each website was also noted. The mean DISCERN score for all websites analyzed was 39.5, considered "poor," while only 44.6% of sites were considered "fair" or "good." Governmental and nonprofit organization (NPO) websites had the highest average DISCERN score. The mean HA-specific content score was 8.6 (range, 2 to 16). The commercial website category had the highest average HA-specific content score, followed by the governmental and NPO category. Sites that bore the HONcode certification obtained significantly higher DISCERN scores than those without the certification (P = .0032) but did not obtain significantly higher HA-specific content scores. "Hip arthroscopy" is a fairly general term, and there is significant variability in the quality of HA information available online. The HONcode is useful to identify quality patient information websites; however, it is not commonly used in HA-specific websites and does not encompass all quality websites about HA. This study increases awareness of the quality of information on HA available online. Copyright © 2016 Arthroscopy Association of North America. Published by Elsevier Inc. All rights reserved.

Analysis of the quality of hospital information systems audit trails

PubMed Central

2013-01-01

Background Audit Trails (AT) are fundamental to information security in order to guarantee access traceability but can also be used to improve Health information System’s (HIS) quality namely to assess how they are used or misused. This paper aims at analysing the existence and quality of AT, describing scenarios in hospitals and making some recommendations to improve the quality of information. Methods The responsibles of HIS for eight Portuguese hospitals were contacted in order to arrange an interview about the importance of AT and to collect audit trail data from their HIS. Five institutions agreed to participate in this study; four of them accepted to be interviewed, and four sent AT data. The interviews were performed in 2011 and audit trail data sent in 2011 and 2012. Each AT was evaluated and compared in relation to data quality standards, namely for completeness, comprehensibility, traceability among others. Only one of the AT had enough information for us to apply a consistency evaluation by modelling user behaviour. Results The interviewees in these hospitals only knew a few AT (average of 1 AT per hospital in an estimate of 21 existing HIS), although they all recognize some advantages of analysing AT. Four hospitals sent a total of 7 AT – 2 from Radiology Information System (RIS), 2 from Picture Archiving and Communication System (PACS), 3 from Patient Records. Three of the AT were understandable and three of the AT were complete. The AT from the patient records are better structured and more complete than the RIS/PACS. Conclusions Existing AT do not have enough quality to guarantee traceability or be used in HIS improvement. Its quality reflects the importance given to them by the CIO of healthcare institutions. Existing standards (e.g. ASTM:E2147, ISO/TS 18308:2004, ISO/IEC 27001:2006) are still not broadly used in Portugal. PMID:23919501

2015-12-01

Evidence-based health information is a prerequisite for patients with type 2 diabetes to engage in self-management and to make informed medical decisions. The Internet is an important source of health information. In the present study, we systematically assessed formal quality, quality of decision support and usability of German and English language websites on type 2 diabetes. The search term 'type 2 diabetes' was entered in the two most popular search engines. Descriptive data on website quality are presented. Additionally, associations between website quality and affiliation (commercial vs. non-commercial), presence of the HON code quality seal and website traffic were explored. Forty-six websites were included. Most websites provided basic information necessary for decision-making, while only one website also provided decision support. Websites with a HON code had significantly better formal quality than websites without HON code. We found a highly significant correlation between usability and website traffic and a significant correlation between formal quality and website traffic. Most websites do not provide sufficient information to support patients in medical decision-making. Our finding that usability and website traffic are tightly associated is consistent with previous research indicating that design is the most important cue for users assessing website credibility. © The Author (2014).

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

Five hundred Web sites were identified by the most popular web search engines. Results: Two hundred forty-five Web sites were assessed after duplicates and irrelevant sources were excluded. Only 72 (29%) Web sites addressed >16 items, and scores tended to be higher for professional societies, portals, patient groups, health departments, and academic centers than for Web sites developed by physicians, respectively. The Ensuring Quality Information for Patients score achieved by Web sites ranged between 8 and 29 of total 36 points, with a median value of 16 points (interquartile range, 14–18). The top 10 Web sites with the highest scores were identified. Conclusions: The quality of patient information on liposuction available in the Internet is poor, and existing Web sites show substantial shortcomings. There is an urgent need for improvement in offering superior quality information on liposuction for patients intending to undergo this procedure. PMID:27482498

Study Design An Internet-based evaluation of Web sites regarding lumbar fusion. Objective The Internet has become a major resource for patients; however, the quality and readability of Internet information regarding lumbar fusion is unclear. The objective of this study is to evaluate the quality and readability of Internet information regarding lumbar fusion and to determine whether these measures changed with Web site modality, complexity of the search term, or Health on the Net Code of Conduct certification. Methods Using five search engines and three different search terms of varying complexity (“low back fusion,” “lumbar fusion,” and “lumbar arthrodesis”), we identified and reviewed 153 unique Web site hits for information quality and readability. Web sites were specifically analyzed by search term and Web site modality. Information quality was evaluated on a 5-point scale. Information readability was assessed using the Flesch-Kincaid score for reading grade level. Results The average quality score was low. The average reading grade level was nearly six grade levels above that recommended by National Work Group on Literacy and Health. The quality and readability of Internet information was significantly dependent on Web site modality. The use of more complex search terms yielded information of higher reading grade level but not higher quality. Conclusions Higher-quality information about lumbar fusion conveyed using language that is more readable by the general public is needed on the Internet. It is important for health care providers to be aware of the information accessible to patients, as it likely influences their decision making regarding care. PMID:26933614

Cancer center websites are trusted sources of internet information about treatment options for prostate cancer. The quality of information on these websites is unknown. The objective of this study was to evaluate the quality of information on cancer center websites addressing prostate cancer treatment options, outcomes, and toxicity. We evaluated the websites of all National Cancer Institute-designated cancer centers to determine if sufficient information was provided to address eleven decision-specific knowledge questions from the validated Early Prostate Cancer Treatment Decision Quality Instrument. We recorded the number of questions addressed, the number of clicks to reach the prostate cancer-specific webpage, evaluation time, and Spanish and mobile accessibility. Correlation between evaluation time and questions addressed were calculated using the Pearson coefficient. Sixty-three websites were reviewed. Eighty percent had a prostate cancer-specific webpage reached in a median of three clicks. The average evaluation time was 6.5 minutes. Information was available in Spanish on 24% of sites and 59% were mobile friendly. Websites provided sufficient information to address, on average, 19% of questions. No website addressed all questions. Evaluation time correlated with the number of questions addressed (R(2) = 0.42, p < 0.001). Cancer center websites provide insufficient information for men with localized prostate cancer due to a lack of information about and direct comparison of specific treatment outcomes and toxicities. Information is also less accessible in Spanish and on mobile devices. These data can be used to improve the quality and accessibility of prostate cancer treatment information on cancer center websites.

Switching health insurers: the role of price, quality and consumer information search.

Boonen, Lieke H H M; Laske-Aldershof, Trea; Schut, Frederik T

2016-04-01

We examine the impact of price, service quality and information search on people's propensity to switch health insurers in the competitive Dutch health insurance market. Using panel data from annual household surveys and data on health insurers' premiums and quality ratings over the period 2006-2012, we estimate a random effects logit model of people's switching decisions. We find that switching propensities depend on health plan price and quality, and on people's age, health, education and having supplementary or group insurance. Young people (18-35 years) are more sensitive to price, whereas older people are more sensitive to quality. Searching for health plan information has a much stronger impact on peoples' sensitivity to price than to service quality. In addition, searching for health plan information has a stronger impact on the switching propensity of higher than lower educated people, suggesting that higher educated people make better use of available health plan information. Finally, having supplementary insurance significantly reduces older people's switching propensity.

Image gathering and restoration - Information and visual quality

Mccormick, Judith A.; Alter-Gartenberg, Rachel; Huck, Friedrich O.

1989-01-01

A method is investigated for optimizing the end-to-end performance of image gathering and restoration for visual quality. To achieve this objective, one must inevitably confront the problems that the visual quality of restored images depends on perceptual rather than mathematical considerations and that these considerations vary with the target, the application, and the observer. The method adopted in this paper is to optimize image gathering informationally and to restore images interactively to obtain the visually preferred trade-off among fidelity resolution, sharpness, and clarity. The results demonstrate that this method leads to significant improvements in the visual quality obtained by the traditional digital processing methods. These traditional methods allow a significant loss of visual quality to occur because they treat the design of the image-gathering system and the formulation of the image-restoration algorithm as two separate tasks and fail to account for the transformations between the continuous and the discrete representations in image gathering and reconstruction.

Evaluation of the Quality of Online Information for Patients with Rare Cancers: Thyroid Cancer.

2017-01-24

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

Metal-on-Metal Total Hip Arthroplasty: Quality of Online Patient Information.

Crozier-Shaw, Geoff; Queally, Joseph M; Quinlan, John F

2017-03-01

Metal-on-metal total hip arthroplasty (THA) has generated much attention in the media because of early failure of certain implant systems. This study assessed the quality, accuracy, and readability of online information on metal-on-metal THA. The search terms "metal-on-metal hip replacement" and "metal hip replacement" were entered into the 3 most popular search engines. Information quality was assessed with the DISCERN score and a specific metal-on-metal THA content score. Accuracy of information was assessed with a customized score. Readability of the websites was assessed with the Flesch-Kincaid grade level score. A total of 61 unique websites were assessed. For 56% of websites, the target audience was patients. Media or medicolegal sources accounted for 44% of websites. As assessed by DISCERN (range, 16-80) and metal-on-metal THA (range, 0-25) scores, quality of the websites was moderate at best (47.1 and 9.6, respectively). Accuracy (range, 0-8) of the information presented also was moderate, with a mean score of 6.6. Media and medicolegal websites had the lowest scores for both quality and accuracy, despite making up the greatest proportion of sites assessed. Only 1 website (2%) had a Flesch-Kincaid grade level at or less than the recommended level of 8th grade. This study found that online information on metal-on-metal THA was of poor quality, often was inaccurate, and was presented at an inappropriately high reading level, particularly for media and medicolegal websites. Health care providers should counsel patients on the quality of information available and recommend appropriate online resources. [Orthopedics. 2017; 40(2):e262-e268.].

Varady, N H; Dee, E C; Katz, J N

2018-05-23

Osteoarthritis is one of the leading causes of global disability. Numerous studies have assessed the quality and content of online health information; however, how information content varies between multiple countries remains unknown. The primary objective of this study was to examine how the quality and content of online health information on osteoarthritis compares on an international scale. Internet searches for the equivalent of "knee osteoarthritis treatment" were performed in ten countries around the world. For each country, the first ten websites were evaluated using a custom scoring form examining: website type; quality and reliability using the DISCERN and Health-on-the-Net (HON) frameworks; and treatment content based on three international osteoarthritis treatment guidelines. Consistency of search results between countries speaking the same language was also assessed. Significant differences in all scoring metrics existed between countries speaking different languages. Western countries scored higher than more eastern countries, there were no differences between the United States and Mexico in any of the scoring metrics, and HON certified websites were of higher quality and reliability. Searches in different countries speaking the same language had at least 70% overlap. The quality of online health information on knee osteoarthritis varies significantly between countries speaking different languages. Differential access to quality, accurate, and safe health information online may represent a novel but important health inequality. Future efforts are needed to translate online health resources into additional languages. In the interim, patients may seek websites that display the HON seal. Copyright © 2018.

Publicly disclosed information about the quality of health care: response of the US public

PubMed Central

Schneider, E; Lieberman, T

2001-01-01

Public disclosure of information about the quality of health plans, hospitals, and doctors continues to be controversial. The US experience of the past decade suggests that sophisticated quality measures and reporting systems that disclose information on quality have improved the process and outcomes of care in limited ways in some settings, but these efforts have not led to the "consumer choice" market envisaged. Important reasons for this failure include limited salience of objective measures to consumers, the complexity of the task of interpretation, and insufficient use of quality results by organised purchasers and insurers to inform contracting and pricing decisions. Nevertheless, public disclosure may motivate quality managers and providers to undertake changes that improve the delivery of care. Efforts to measure and report information about quality should remain public, but may be most effective if they are targeted to the needs of institutional and individual providers of care. Key Words: public disclosure; quality of health care; quality improvement PMID:11389318

To investigate the relationship between the use of health information technology (HIT) and physician perceptions of providing high-quality care and to determine whether this relationship has changed over time. We used 2 waves of longitudinal data from the Community Tracking Study Physician Surveys, 2000-2001 and 2004-2005. Three measures of HIT were examined: a binary variable measuring the use of at least 1 type of HIT, a continuous variable measuring the total number of HIT types, and a binary variable measuring use of all 5 HIT types related to "meaningful use" of HIT as defined by Centers for Medicare and Medicaid Services. Three multivariate models were estimated to study the effect of each HIT measure on physicians' perception of providing high-quality care. Individual fixed-effects estimation also was used to control for individual time-invariant factors. Using at least 1 type of HIT significantly enhanced physicians' perception of providing high-quality care in 2000-2001, but not in 2004-2005. The marginal effect of adding 1 extra HIT type was positive and statistically significant in both periods. The association between using all 5 HIT types related to meaningful use and perceived quality was statistically significant in 2000-2001, but not in 2004-2005. Health information technology has become a multifunctional system and appears to have enhanced physicians' perception of providing high-quality care. Physicians' perceptions of medical care quality improved as the number of HIT types used increased. This study supports more extensive use of HIT in physician practices.

1994-09-01

The aim of this study initiated in May 1990 was to evaluate the quality of the medical data collected from the main hospital of the "Hospices Civils de Lyon", Edouard Herriot Hospital. We studied a random sample of 593 discharge abstracts from 12 wards of the hospital. Quality control was performed by checking multi-hospitalized patients' personal data, checking that each discharge abstract was exhaustive, examining the quality of abstracting, studying diagnoses and medical procedures coding, and checking data entry. Assessment of personal data showed a 4.4% error rate. It was mainly accounted for by spelling mistakes in surnames and first names, and mistakes in dates of birth. The quality of a discharge abstract was estimated according to the two purposes of the medical information system: description of hospital morbidity per patient and Diagnosis Related Group's case mix. Error rates in discharge abstracts were expressed in two ways: an overall rate for errors of concordance between Discharge Abstracts and Medical Records, and a specific rate for errors modifying classification in Diagnosis Related Groups (DRG). For abstracting medical information, these error rates were 11.5% (SE +/- 2.2) and 7.5% (SE +/- 1.9) respectively. For coding diagnoses and procedures, they were 11.4% (SE +/- 1.5) and 1.3% (SE +/- 0.5) respectively. For data entry on the computerized data base, the error rate was 2% (SE +/- 0.5) and 0.2% (SE +/- 0.05). Quality control must be performed regularly because it demonstrates the degree of participation from health care teams and the coherence of the database.(ABSTRACT TRUNCATED AT 250 WORDS)

Healthcare delivery systems: designing quality into health information systems.

To ensure that quality is 'engineered in' a holistic, integrated and quality approach is required, and Total Quality Management (TQM) principles are the obvious foundations for this. This paper describes a novel approach to viewing the operations of a healthcare provider where electronic means could be used to distribute information (including electronic fund settlements), building around the Full Service Provider core. Specifically, an approach called the "triple pair flow" model is used to provide a view of healthcare delivery that is integrated, yet detailed, and that combines the strategic enterprise view with a business process view.

2014-01-01

The purpose of this paper is to explore library and information service impact on patient care quality. A large-scale critical incident survey of physicians and residents at 56 library sites serving 118 hospitals in the USA and Canada. Respondents were asked to base their answers on a recent incident in which they had used library resources to search for information related to a specific clinical case. Of 4,520 respondents, 75 percent said that they definitely or probably handled patient care differently using information obtained through the library. In a multivariate analysis, three summary clinical outcome measures were used as value and impact indicators: first, time saved; second, patient care changes; and third, adverse events avoided. The outcomes were examined in relation to four information access methods: first, asking librarian for assistance; second, performing search in a physical library; third, searching library's web site; or fourth, searching library resources on an institutional intranet. All library access methods had consistently positive relationships with the clinical outcomes, providing evidence that library services have a positive impact on patient care quality. Electronic collections and services provided by the library and the librarian contribute to patient care quality.

This study aims to assess and compare melanoma information quality in Hungarian, Czech, and German languages on the Internet. We used country-specific Google search engines to retrieve the first 25 uniform resource locators (URLs) by searching the word "melanoma" in the given language. Using the automated toolbar of Health On the Net Foundation (HON), we assessed each Web site for HON certification based on the Health On the Net Foundation Code of Conduct (HONcode). Information quality was determined using a 35-point checklist created by Bichakjian et al. (J Clin Oncol 20:134-141, 2002), with the NCCN melanoma guideline as control. After excluding duplicate and link-only pages, a total of 24 Hungarian, 18 Czech, and 21 German melanoma Web sites were evaluated and rated. The amount of HON certified Web sites was the highest among the German Web pages (19%). One of the retrieved Hungarian and none of the Czech Web sites were HON certified. We found the highest number of Web sites containing comprehensive, correct melanoma information in German language, followed by Czech and Hungarian pages. Although the majority of the Web sites lacked data about incidence, risk factors, prevention, treatment, work-up, and follow-up, at least one comprehensive, high-quality Web site was found in each language. Several Web sites contained incorrect information in each language. While a small amount of comprehensive, quality melanoma-related Web sites was found, most of the retrieved Web content lacked basic disease information, such as risk factors, prevention, and treatment. A significant number of Web sites contained malinformation. In case of melanoma, primary and secondary preventions are of especially high importance; therefore, the improvement of disease information quality available on the Internet is necessary.

For more than 30 years, there has been close cooperation between Japanese and German scientists with regard to information systems in health care. Collaboration has been formalized by an agreement between the respective scientific associations. Following this agreement, two joint workshops took place to explore the similarities and differences of electronic health record systems (EHRS) against the background of the two national healthcare systems that share many commonalities. To establish a framework and requirements for the quality of EHRS that may also serve as a basis for comparing different EHRS. Donabedian's three dimensions of quality of medical care were adapted to the outcome, process, and structural quality of EHRS and their management. These quality dimensions were proposed before the first workshop of EHRS experts and enriched during the discussions. The Quality Requirements Framework of EHRS (QRF-EHRS) was defined and complemented by requirements for high quality EHRS. The framework integrates three quality dimensions (outcome, process, and structural quality), three layers of information systems (processes and data, applications, and physical tools) and three dimensions of information management (strategic, tactical, and operational information management). Describing and comparing the quality of EHRS is in fact a multidimensional problem as given by the QRF-EHRS framework. This framework will be utilized to compare Japanese and German EHRS, notably those that were presented at the second workshop.

Information processing during NREM sleep and sleep quality in insomnia.

PubMed

Ceklic, Tijana; Bastien, Célyne H

2015-12-01

Insomnia sufferers (INS) are cortically hyperaroused during sleep, which seems to translate into altered information processing during nighttime. While information processing, as measured by event-related potentials (ERPs), during wake appears to be associated with sleep quality of the preceding night, the existence of such an association during nighttime has never been investigated. This study aims to investigate nighttime information processing among good sleepers (GS) and INS while considering concomitant sleep quality. Following a multistep clinical evaluation, INS and GS participants underwent 4 consecutive nights of PSG recordings in the sleep laboratory. Thirty nine GS (mean age 34.56±9.02) and twenty nine INS (mean age 43.03±9.12) were included in the study. ERPs (N1, P2, N350) were recorded all night on Night 4 (oddball paradigm) during NREM sleep. Regardless of sleep quality, INS presented a larger N350 amplitude during SWS (p=0.042) while GS showed a larger N350 amplitude during late-night stage 2 sleep (p=0.004). Regardless of diagnosis, those who slept objectively well showed a smaller N350 amplitude (p=0.020) while those who slept subjectively well showed a smaller P2 (p<0.001) and N350 amplitude (p=0.006). Also, those who reported an objectively bad night as good showed smaller P2 (p< 0.001) and N350 (p=0.010) amplitudes. Information processing seems to be associated with concomitant subjective and objective sleep quality for both GS and INS. However, INS show an alteration in information processing during sleep, especially for inhibition processes, regardless of their sleep quality. Copyright © 2015 Elsevier B.V. All rights reserved.

Internet-derived health care information is increasingly accessed by patients, yet its quality and accuracy is variable and unregulated. The aim of this study was to assess the information available regarding common gastrointestinal cancers via three internet search engines (Google, Yahoo and Bing). The top 30 websites for each of the terms: oesophageal, gastric, pancreatic, colon and rectal cancer were evaluated (University of Michigan Consumer Health Website Checklist) and scored [-80 (poor) to 90 (excellent)]. The median score was 53 (-7 to 81) and was significantly higher for oesophageal (61) and pancreatic (65) cancer websites, compared with gastric (49), colon (48) and rectal cancer (50) (p = 0.014). Median scores related to charitable organisations were significantly better than academic, commercial, news agency, care provider, layperson and medical information websites collectively (79 vs. 42, p < 0.0001). Overall quality of internet-derived gastrointestinal cancer information remains poor and patients and clinicians should be aware.

Radiation oncology (RO) residency applicants commonly use Internet resources for information on residency programs. The purpose of this study is to assess the accessibility, availability, and quality of online information for RO graduate medical education. Accessibility of online information was determined by surveying databases for RO residency programs within the Fellowship Residency Electronic Interactive Data Access System (FREIDA) of the American Medical Association, the Accreditation Council for Graduate Medical Education (ACGME), and Google search. As of June 30, 2015, websites were assessed for presence, accessibility, and overall content availability based on a 55-item list of desired features based on 13 program features important to previously surveyed applicants. Quality scoring of available content was performed based on previously published Likert scale variables deemed desirable to RO applicants. Quality score labels were given based on percentage of desired information presented. FREIDA and ACGME databases listed 89% and 98% of program websites, respectively, but only 56% and 52% of links routed to a RO department-specific website, respectively. Google search obtained websites for 98% of programs and 95% of links routed to RO department-specific websites. The majority of websites had program descriptions (98%) and information on staff. However, resident information was more limited (total number [42%], education [47%], previous residents [28%], positions available [35%], contact information [13%]). Based on quality scoring, program websites contained only 47% of desired information on average. Only 13% of programs had superior websites containing 80% or more of desired information. Compared with Google, the FREIDA and ACGME program databases provide limited access to RO residency websites. The overall information availability and quality of information within RO residency websites varies widely. Applicants and programs may benefit from improved

We examine consumers' use of publicized quality information in Medicare home health care markets, where consumer cost sharing and travel costs are absent. We report two findings. First, agencies with high quality scores are more likely to be preferred by consumers after the introduction of a public reporting program than before. Second, consumers' use of publicized quality information differs by patient group. Community-based patients have slightly larger responses to public reporting than hospital-discharged patients. Patients with functional limitations at the start of their care, at least among hospital-discharged patients, have a larger response to the reported functional outcome measure than those without functional limitations. In all cases of significant marginal effects, magnitudes are small. We conclude that the current public reporting approach is unlikely to have critical impacts on home health agency choice. Identifying and releasing quality information that is meaningful to consumers may help increase consumers' use of public reports. © The Author(s) 2015.

In all cases of significant marginal effects, magnitudes are small. We conclude that the current public reporting approach is unlikely to have critical impacts on home health agency choice. Identifying and releasing quality information that is meaningful to consumers may help increase consumers’ use of public reports. PMID:26719047

Background Low quality of medication information in discharge summaries from hospitals may jeopardize optimal therapy and put the patient at risk for medication errors and adverse drug events. Objective To audit the quality of medication information in discharge summaries and explore factors associated with the quality. Setting Helgelandssykehuset Mo i Rana, a rural hospital in central Norway. Method For each month in 2013, we randomly selected 60 discharge summaries from the Department of Medicine and Surgery (totally 720) and evaluated the medication information using eight Norwegian quality criteria. Main outcome measure Mean score per discharge summary ranging from 0 (lowest quality) to 16 (highest quality). Results Mean score per discharge summary was 7.4 (SD 2.8; range 0-14), significantly higher when evaluating medications used regularly compared to mediations used as needed (7.80 vs. 6.52; p < 0.001). Lowest score was achieved for quality criteria concerning generic names, indications for medication use, reasons why changes had been made and information about the source for information. Factors associated with increased quality scores are increasing numbers of medications and male patients. Increasing age seemed to be associated with a reduced score, while type of department was not associated with the quality. Conclusion In discharge summaries from 2013, we identified a low quality of medication information in accordance with the Norwegian quality criteria. Actions for improvement are necessary and follow-up studies to monitor quality are needed.

2013-04-01

Using the Institute of Medicine framework that outlines the domains of quality, this article considers four key aspects of health care delivery which have the potential to significantly affect the quality of health care within the pediatric intensive care unit. The discussion covers: performance improvement and how existing methods for reporting, review, and analysis of medical error relate to patient care; team composition and workflow; and the impact of information technologies on clinical practice. Also considered is how protocol-driven and standardized practice affects both patients and the fiscal interests of the health care system.

In today's technologically advanced world, 75% of patients have used Google to search for health information. As a result, health care professionals fear that patients may be misinformed. Currently, there is a paucity of data on the quality and readability of Web-based health information on fractures. In this study, we assessed the quality and readability of Web-based health information related to the 10 most common fractures. Using the Google search engine, we assessed websites from the first results page for the 10 most common fractures using lay search terms. Website quality was measured using the DISCERN instrument, which scores websites as very poor (15-22.5), poor (22.5-37.5), fair (37.5-52.5), good (52.5-67.5), or excellent (67.5-75). The presence of Health on the Net code (HONcode) certification was assessed for all websites. Website readability was measured using the Flesch Reading Ease Score (0-100), where 60-69 is ideal for the general public, and the Flesch-Kincaid Grade Level (FKGL; -3.4 to ∞), where the mean FKGL of the US adult population is 8. Overall, website quality was "fair" for all fractures, with a mean (standard deviation) DISCERN score of 50.3 (5.8). The DISCERN score correlated positively with a higher website position on the search results page (r(2)=0.1, P=.002) and with HONcode certification (P=.007). The mean (standard deviation) Flesch Reading Ease Score and FKGL for all fractures were 62.2 (9.1) and 6.7 (1.6), respectively. The quality of Web-based health information on fracture care is fair, and its readability is appropriate for the general public. To obtain higher quality information, patients should select HONcode-certified websites. Furthermore, patients should select websites that are positioned higher on the results page because the Google ranking algorithms appear to rank the websites by quality.

Starting with clinically motivated projects, the national quality assurance program has established a legislative obligatory framework. Annual feedback of results is an important means of quality control. The annual reports cover quality-related information with high granularity. A synopsis for corporate management is missing, however. Therefore, the results of the University Clinics in Greifswald, Germany, have been analyzed and aggregated to support hospital management. Strengths were identified by the ranking of results within the state for each quality indicator, weaknesses by the comparison with national reference values. The assessment was aggregated per clinical discipline and per category (indication, process, and outcome). A composition of quality indicators was claimed multiple times. A coherent concept is still missing. The method presented establishes a plausible summary of strengths and weaknesses of a hospital from the point of view of the national quality assurance program. Nevertheless, further adaptation of the program is needed to better assist corporate management.

Diagnostic self-tests (tests on body materials that are initiated by consumers with the aim of diagnosing a disorder or risk factor) are becoming increasingly available. Although the pros and cons of self-testing are currently not clear, it is an existing phenomenon that is likely to gain further popularity. To examine consumers' use of and needs for information about self-testing, and to assess the quality of consumer information provided with home test kits, as perceived by consumers and as assessed using a checklist of quality criteria. A cross-sectional Internet survey among 305 self-testers assessed their use of and needs for information and their perception of the quality of consumer information provided with self-test kits. A meta-search engine was used to identify Dutch and English consumer information for home diagnostic tests available online at the time of the study. The quality of this consumer information was evaluated using a checklist of quality criteria. The consumers' information needs were in line with the most frequently used information, and the information was perceived as being of moderate to good quality. The information was mostly in agreement with clinical practice guidelines, although information on reliability and follow-up behaviour was limited. Approximately half of the instruction leaflets did not include information on the target group of the test. Although generally of moderate to good quality, some aspects of the information provided were in many cases insufficient. European legislation concerning self-tests and accompanying information needs to be adapted and adhered to more closely. © 2012 John Wiley & Sons Ltd.

The World Wide Web has grown during the last years to a considerable source of medical information for experts as well as for laymen and patients. The quality of this information is subjected to some limitation linked with the structure of the Internet and the management of Internet pages. The cross- sectional study presented evaluates and compares quality and reliability of information with respect of osteosarcoma in the most common German-language Internet pages for medical information. As both, one of the most common primary malignant bone tumors and its peak of incidence at the age of childhood and youth, osteosarcoma is considered of significant importance in orthopedic oncology.

An Integrated Information System for Supporting Quality Management Tasks

Beyer, N.; Helmreich, W.

2004-08-01

In a competitive environment, well defined processes become the strategic advantage of a company. Hence, targeted Quality Management ensures efficiency, trans- parency and, ultimately, customer satisfaction. In the particular context of a Space Test Centre, a num- ber of specific Quality Management standards have to be applied. According to the revision of ISO 9001 dur- ing 2000, and due to the adaptation of ECSS-Q20-07, process orientation and data analysis are key tasks for ensuring and evaluating the efficiency of a company's processes. In line with these requirements, an integrated management system for accessing the necessary infor- mation to support Quality Management and other proc- esses has been established. Some of its test-related fea- tures are presented here. Easy access to the integrated management system from any work place at IABG's Space Test Centre is ensured by means of an intranet portal. It comprises a full set of quality-related process descriptions, information on test facilities, emergency procedures, and other relevant in- formation. The portal's web interface provides direct access to a couple of external applications. Moreover, easy updating of all information and low cost mainte- nance are features of this integrated information system. The timely and transparent management of non- conformances is covered by a dedicated NCR database which incorporates full documentation capability, elec- tronic signature and e-mail notification of concerned staff. A search interface allows for queries across all documented non-conformances. Furthermore, print ver- sions can be generated at any stage in the process, e.g. for distribution to customers. Feedback on customer satisfaction is sought through a web-based questionnaire. The process is initiated by the responsible test manager through submission of an e- mail that contains a hyperlink to a secure website, ask- ing the customer to complete the brief online form, which is directly fed to a database

The internet is frequently used by patients for researching information regarding breast cancer. This study aims to assess the quality of these websites using validated tools. The term 'breast cancer' was searched for in 3 search engines. The top 20 results were selected, and duplicates and irrelevant websites were excluded. 26/34 websites were analysed using the DISCERN Plus tool, HONcode and the JAMA benchmarks. 46% of the websites were classed as 'excellent' when assessed with the DISCERN tool. The range of DISCERN scores was wide (range: 25-74). Nine websites were found to be HONcode certified. Seven websites complied with all four JAMA benchmarks. This study shows the quality of breast cancer information on the internet is on the whole good; however the range of quality is wide. We recommend healthcare professionals use all 3 tools together to establish which websites are best to advise which websites patients should trust. Copyright © 2015 Elsevier Ltd.

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

Spatial Data Quality Control Procedure applied to the Okavango Basin Information System

NASA Astrophysics Data System (ADS)

Butchart-Kuhlmann, Daniel

2014-05-01

Spatial data is a powerful form of information, capable of providing information of great interest and tremendous use to a variety of users. However, much like other data representing the 'real world', precision and accuracy must be high for the results of data analysis to be deemed reliable and thus applicable to real world projects and undertakings. The spatial data quality control (QC) procedure presented here was developed as the topic of a Master's thesis, in the sphere of and using data from the Okavango Basin Information System (OBIS), itself a part of The Future Okavango (TFO) project. The aim of the QC procedure was to form the basis of a method through which to determine the quality of spatial data relevant for application to hydrological, solute, and erosion transport modelling using the Jena Adaptable Modelling System (JAMS). As such, the quality of all data present in OBIS classified under the topics of elevation, geoscientific information, or inland waters, was evaluated. Since the initial data quality has been evaluated, efforts are underway to correct the errors found, thus improving the quality of the dataset.

Today we are in the midst of information and 'total quality' revolutions. At the NASA STI Program's Center for AeroSpace Information (CASI), we are focused on using continuous improvements techniques to enrich today's services and products and to ensure that tomorrow's technology supports the TQM-based improvement of future STI program products and services. The Continuous Improvements Program at CASI is the foundation for Total Quality Management in products and services. The focus is customer-driven; its goal, to identify processes and procedures that can be improved and new technologies that can be integrated with the processes to gain efficiencies, provide effectiveness, and promote customer satisfaction. This Program seeks to establish quality through an iterative defect prevention approach that is based on the incorporation of standards and measurements into the processing cycle. Four projects are described that utilize cross-functional, problem-solving teams for identifying requirements and defining tasks and task standards, management participation, attention to critical processes, and measurable long-term goals. The implementation of these projects provides the customer with measurably improved access to information that is provided through several channels: the NASA STI Database, document requests for microfiche and hardcopy, and the Centralized Help Desk.

To analyze the extent to which Spanish leaflets and drug information on the Net met quality criteria. A descriptive study was conducted comparing readability (REA) and comprehensibility (COM) criteria of a random sample of 77 marketed products of the 12 active ingredients most frequently sold in 2010 in Spain. Leaflets were approved by the Spanish Agency for Medication (AEMPS). Flesch index, DISCERN, ELF, MIDAS and CIRF scales were used to evaluate quality criteria. COM assessment yielded between 63 and 77% of the maximum possible scores on the scales. None of the websites or leaflets met all the quality criteria of the DISCERN, CIRF or MIDAS scales. Four (3%) leaflets met all the 22 quality criteria of ELF. The leaflets showed shortcomings regarding: medication benefits (17 required substantial improvements, 31.5%), correct forms of storage (13, 24.1%), contraindications (12, 22.2%), side effects (11, 20.4%) and precautions to be taken (9, 16.7%). The quality of the information approved by the AEMPS is superior to that which can be found by surfing the Net. More specific information on precautions, complications and how to avoid common patient errors would allow patients the best chance to contribute to their own clinical safety.

Accessibility, nature and quality of health information on the Internet: a survey on osteoarthritis.

Maloney, S; Ilic, D; Green, S

2005-03-01

This study aims to determine the quality and validity of information available on the Internet about osteoarthritis and to investigate the best way of sourcing this information. Keywords relevant to osteoarthritis were searched across 15 search engines representing medical, general and meta-search engines. Search engine efficiency was defined as the percentage of unique and relevant websites from all websites returned by each search engine. The quality of relevant information was appraised using the DISCERN tool and the concordance of the information offered by the website with the available evidence about osteoarthritis determined. A total of 3443 websites were retrieved, of which 344 were identified as unique and providing information relevant to osteoarthritis. The overall quality of website information was poor. There was no significant difference between types of search engine in sourcing relevant information; however, the information retrieved from medical search engines was of a higher quality. Fewer than a third of the websites identified as offering relevant information cited evidence to support their recommendations. Although the overall quality of website information about osteoarthritis was poor, medical search engines may provide consumers with the opportunity to source high-quality health information on the Internet. In the era of evidence-based medicine, one of the main obstacles to the Internet reaching its potential as a medical resource is the failure of websites to incorporate and attribute evidence-based information.

The reliability-quality relationship for quality systems and quality risk management.

PubMed

Claycamp, H Gregg; Rahaman, Faiad; Urban, Jason M

2012-01-01

Engineering reliability typically refers to the probability that a system, or any of its components, will perform a required function for a stated period of time and under specified operating conditions. As such, reliability is inextricably linked with time-dependent quality concepts, such as maintaining a state of control and predicting the chances of losses from failures for quality risk management. Two popular current good manufacturing practice (cGMP) and quality risk management tools, failure mode and effects analysis (FMEA) and root cause analysis (RCA) are examples of engineering reliability evaluations that link reliability with quality and risk. Current concepts in pharmaceutical quality and quality management systems call for more predictive systems for maintaining quality; yet, the current pharmaceutical manufacturing literature and guidelines are curiously silent on engineering quality. This commentary discusses the meaning of engineering reliability while linking the concept to quality systems and quality risk management. The essay also discusses the difference between engineering reliability and statistical (assay) reliability. The assurance of quality in a pharmaceutical product is no longer measured only "after the fact" of manufacturing. Rather, concepts of quality systems and quality risk management call for designing quality assurance into all stages of the pharmaceutical product life cycle. Interestingly, most assays for quality are essentially static and inform product quality over the life cycle only by being repeated over time. Engineering process reliability is the fundamental concept that is meant to anticipate quality failures over the life cycle of the product. Reliability is a well-developed theory and practice for other types of manufactured products and manufacturing processes. Thus, it is well known to be an appropriate index of manufactured product quality. This essay discusses the meaning of reliability and its linkages with quality

2008-01-01

To assess the quality of information provided to consumers by websites marketing medical home diagnostic tests. A cross-sectional analysis of a database developed from searching targeted websites. Data sources were websites written in English which marketed medical home diagnostic tests. A meta-search engine was used to identify the first 20 citations for each type of home diagnostic medical test. Relevant websites limited to those written in English were reviewed independently and in triplicate, with disputes resolved by two further reviewers. Information on the quality of these sites was extracted using a pre-piloted performer. 168 websites were suitable for inclusion in the review. The quality of these sites showed marked variation. Only 24 of 168 (14.2%) complied with at least three-quarters of the quality items and just over half (95 of 168, 56.5%) reported official approval or certification of the test. Information on accuracy of the test marketed was reported by 87 of 168 (51.7%) websites, with 15 of 168 (8.9%) providing a scientific reference. Instructions for use of the product were found in 97 of 168 (57.9%). However, the course of action to be taken after obtaining the test result was stated in only 63 of 168 (37.5%) for a positive result and 43 of 168 (25.5%) for a negative result. The quality of information posted on commercial websites marketing home tests online is unsatisfactory and potentially misleading for consumers.

Using Feedback from Data Consumers to Capture Quality Information on Environmental Research Data

NASA Astrophysics Data System (ADS)

Devaraju, A.; Klump, J. F.

2015-12-01

Data quality information is essential to facilitate reuse of Earth science data. Recorded quality information must be sufficient for other researchers to select suitable data sets for their analysis and confirm the results and conclusions. In the research data ecosystem, several entities are responsible for data quality. Data producers (researchers and agencies) play a major role in this aspect as they often include validation checks or data cleaning as part of their work. It is possible that the quality information is not supplied with published data sets; if it is available, the descriptions might be incomplete, ambiguous or address specific quality aspects. Data repositories have built infrastructures to share data, but not all of them assess data quality. They normally provide guidelines of documenting quality information. Some suggests that scholarly and data journals should take a role in ensuring data quality by involving reviewers to assess data sets used in articles, and incorporating data quality criteria in the author guidelines. However, this mechanism primarily addresses data sets submitted to journals. We believe that data consumers will complement existing entities to assess and document the quality of published data sets. This has been adopted in crowd-source platforms such as Zooniverse, OpenStreetMap, Wikipedia, Mechanical Turk and Tomnod. This paper presents a framework designed based on open source tools to capture and share data users' feedback on the application and assessment of research data. The framework comprises a browser plug-in, a web service and a data model such that feedback can be easily reported, retrieved and searched. The feedback records are also made available as Linked Data to promote integration with other sources on the Web. Vocabularies from Dublin Core and PROV-O are used to clarify the source and attribution of feedback. The application of the framework is illustrated with the CSIRO's Data Access Portal.

Patients often use the internet as a source of information about their condition and treatments. However, this information is unregulated and varies in quality. To evaluate the readability and quality of online information for pediatric and adult patients and caregivers regarding sclerotherapy for venous malformations. "Venous malformation sclerotherapy" was entered into Google, and results were reviewed until 20 sites that satisfied predefined inclusion criteria were identified. Scientific and non-patient-focused web pages were excluded. Readability was assessed using the Flesch Reading Ease Score and American Medical Association reading difficulty recommendations and quality was assessed using Journal of the American Medical Association standards and assessing if the site displayed HONcode (Health on the Net Code) certification. Assessment of the breadth of relevant information was made using a predefined checklist. Forty-nine search engine results were reviewed before 20 sites were identified for analysis. Average Flesch Reading Ease Score was 44 (range: 24.2-70.1), representing a "fairly difficult" reading level. None of the sites had a Flesch Reading Ease Score meeting the American Medical Association recommendation of 80-90. Only one site met all four Journal of the American Medical Association quality criteria (average: 2.1). None of the sites displayed a HONcode seal. The information most frequently found was: sclerotherapy is performed by radiologists, multiple treatments may be needed and surgery is an alternative treatment. Online information regarding sclerotherapy for venous malformations is heterogeneous in quality and breadth of information, and does not meet readability recommendations for patient information. Radiologists should be aware of and account for this when meeting patients.

The American Indian/Alaska Native population experiences a disproportionate burden of disease across a spectrum of conditions. While the recent National Healthcare Disparities Report highlighted differences in quality of care among racial and ethnic groups, there was only very limited information available for American Indians. The Indian Health Service (IHS) is currently enhancing its information systems to improve the measurement of health care quality as well as to support quality improvement initiatives. We summarize current knowledge regarding health care quality for American Indians, highlighting the variation in reported measures in the existing literature. We then discuss how the IHS is using information systems to produce standardized performance measures and present future directions for improving American Indian health care quality.

Surfing for mouth guards: assessing quality of online information.

2011-10-01

The Internet is an easily accessible and commonly used source of health-related information, but evaluations of the quality of this information within the dental trauma field are still lacking. The aims of this study are (i) to present the most current scientific knowledge regarding mouth guards used in sport activities, (ii) to suggest a scoring system to evaluate the quality of information pertaining to mouth guard protection related to World Wide Web sites and (iii) to employ this scoring system when seeking reliable mouth guard-related websites. First, an Internet search using the keywords 'athletic injuries/prevention and control' and 'mouth protector' or 'mouth guards' in English was performed on PubMed, Cochrane, SvedMed+ and Web of Science to identify scientific knowledge about mouth guards. Second, an Internet search using the keywords 'consumer health information Internet', 'Internet information public health' and 'web usage-seeking behaviour' was performed on PubMed and Web of Science to obtain scientific articles seeking to evaluate the quality of health information on the Web. Based on the articles found in the second search, two scoring systems were selected. Then, an Internet search using the keywords 'mouth protector', 'mouth guards' and 'gum shields' in English was performed on the search engines Google, MSN and Yahoo. The websites selected were evaluated for reliability and accuracy. Of the 223 websites retrieved, 39 were designated valid and evaluated. Nine sites scored 22 or higher. The mean total score of the 39 websites was 14.2. Fourteen websites scored higher than the mean total score, and 25 websites scored less. The highest total score, presented by a Public Institution Web site (Health Canada), was 31 from a maximum possible score of 34, and the lowest score was 0. This study shows that there is a high amount of information about mouth guards on the Internet but that the quality of this information varies. It should be the responsibility

Prospective analysis of the quality of Spanish health information web sites after 3 years.

Although the Internet has become an essential source of health information, our study conducted 3 years ago provided evidence of the low quality of Spanish health web sites. The objective of the present study was to evaluate the quality of Spanish health information web sites now, and to compare these results with those obtained 3 years ago. For the original study, the most visited health information web sites were selected through the PageRank® (Google®) system. The present study evaluated the quality of the same web sites from February to May 2013, using the method developed by Bermúdez-Tamayo et al. and HONCode® criteria. The mean quality of the selected web sites was low and has deteriorated since the previous evaluation, especially in regional health services and institutions' web sites. The quality of private web sites remained broadly similar. Compliance with privacy and update criteria also improved in the intervening period. The results indicate that, even in the case of health web sites, design or appearance is more relevant to developers than quality of information. It is recommended that responsible institutions should increase their efforts to eliminate low-quality health information that may further contribute to health problems.

The Internet is increasingly a source of health information for parents, who use the Internet alongside health care providers for immunisation information. Concerns have been raised about the reliability of online immunisation information, however to date there has been no audit of the quality or quantity of what is available to Australian parents. The objective of this study was to address this gap by simulating a general online search for immunisation information, and assessing the quality and quantity of the web sites returned by the search. We used Google trends to identify the most common immunisation search terms used in Australia. The ten most common terms were entered into five search engines and the first ten non-commercial results from each search collated. A quality assessment tool was developed using the World Health Organization Global Advisory Committee on Vaccine Safety (GACVS) criteria for assessing the quality of vaccine safety web sites, and used to assess and score the quality of the sites. Seven hundred web pages were identified, of which 514 were duplicates, leaving 186 pages from 115 web sites which were audited. Forty sites did not include human immunisation information, or presented personal opinion about individuals, and were not scored. Of the 75 sites quality scored, 65 (87%) were supportive of immunisation, while 10 (13%) were not supportive. The overall mean quality score was 57/100 (range 14/100 to 92/100). When stratified by pro and anti-vaccination stance, the average quality score for pro-vaccine sites was 61/100, while the average score for anti-vaccine sites was 30/100. Pro-vaccine information could be divided into three content groups: generalist overview with little detail; well-articulated and understandable detail; and lengthy and highly technical explanations. The main area found to be lacking in pro-vaccine sites was lack of transparent authorship. Our findings suggest a need for information which is easily found

To assess the quality, readability and coverage of website information about herbal remedies for menopausal symptoms. A purposive sample of commercial and non-commercial websites was assessed for quality (DISCERN), readability (SMOG) and information coverage. Non-parametric and parametric tests were used to explain the variability of these factors across types of websites and to assess associations between website quality and information coverage. 39 sites were assessed. Median quality and information coverage scores were 44/80 and 11/30 respectively. The median readability score was 18.7, similar to UK broadsheets. Commercial websites scored significantly lower on quality (p=0.014), but there were no statistical differences for information coverage or readability. There was a significant positive correlation between information quality and coverage scores irrespective of website provider (r=0.69, p<0.001, n=39). Overall website quality and information coverage are poor and the required reading level high. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

With a high rate of recurrence, urolithiasis is a chronic disease that impacts quality of life. The Patient Reported Outcomes Measurement Information System is an NIH validated questionnaire to assess patient quality of life. We evaluated the impact of urolithiasis on quality of life using the NIH-sponsored PROMIS-43 questionnaire. Patients reporting to the kidney stone clinic were interviewed to collect information on stone history and demographic information and were asked to complete the PROMIS-43 questionnaire. Quality of life scores were analyzed using gender and age matched groups for the general US population. Statistical comparisons were made based on demographic information and patient stone history. Statistical significance was P<0.05. 103 patients completed the survey. 36% of respondents were male, the average age of the group was 52 years old, with 58% primary income earners, and 35% primary caregivers. 7% had never passed a stone or had a procedure while 17% passed 10 or more stones in their lifetime. Overall, pain and physical function were worse in patients with urolithiasis. Primary income earners had better quality of life while primary caregivers and those with other chronic medical conditions were worse. Patients on dietary and medical therapy had better quality of life scores. Urolithiasis patients subjectively have worse pain and physical function than the general population. The impact of pain on quality of life was greatest in those patients who had more stone episodes, underscoring the importance of preventive measures. Stone prevention measures improve quality of life. Copyright® by the International Brazilian Journal of Urology.

Background Recently published data show that many women interested in breast augmentation (BA) actively search the Internet for information. The Internet is currently the main source of information on this topic. Objectives Little is known about the quality of available information on the Internet concerning BA. The goal was to evaluate this in a systematic manner using a validated and reproducible tool. Methods Women (n = 96) unrelated to medicine were asked which keywords they would use to search the Internet if they were interested in BA. Five keywords were used. Qualitative and quantitative assessment was performed with the modified Ensuring Quality Information for Patients (EQIP) tool. A total of 2500 websites containing information on BA were identified using Google, Bing, Yahoo, Ask, and AOL. Results Out of 623 eligible websites, only 153 (25%) addressed more than 20 EQIP items. Scores were higher for encyclopaedias and academic websites compared to hospital and practitioner websites. The median EQIP score was only 15 (IQR = 12-20), and quantitative postoperative morbidity and mortality risk estimates were available in only 38% and 25% of the websites, respectively. Major complications (e.g. capsular contraction, implant safety) were mentioned in only 156 (25%) of the websites. Conclusions This is the first assessment of online patient information on BA using the EQIP tool. This analysis demonstrated several shortcomings in the quality of information provided to BA candidates. There is an immediate need for better informative and educational websites regarding BA procedures that are compatible with international quality standards for plastic surgery.

An increasing number of patients, considering aesthetic surgery, use Internet health information as their first source of information. However, the quality of information available in the Internet on phalloplasty is currently unknown. This study aimed to assess the quality of patient information on phalloplasty available in the Internet. The assessment of the Web sites was based on the modified Ensuring Quality Information for Patients (EQIP) instrument (36 items). Three hundred Web sites were identified by the most popular Web search engines. Ninety Web sites were assessed after, duplicates, irrelevant sources and Web sites in other languages rather than English were excluded. Only 16 (18%) Web sites addressed >21 items, and scores tended to be higher for Web sites developed by academic centers and the industry than for Web sites developed by private practicing surgeons. The EQIP score achieved by Web sites ranged between 4 and 29 of the total 36 points, with a median value of 17.5 points (interquartile range, 13-21). The top 5 Web sites with the highest scores were identified. The quality of patient information on phalloplasty in the Internet is substandard, and the existing Web sites present inadequate information. There is a dire need to improve the quality of Internet phalloplasty resources for potential patients who might consider this procedure.

Use of quality information in decision-making about health and social care services--a systematic review.

PubMed

Turnpenny, Agnes; Beadle-Brown, Julie

2015-07-01

User choice and personalisation have been at the centre of health and social care policies in many countries. Exercising choice can be especially challenging for people with long-term conditions (LTC) or disabilities. Information about the quality, cost and availability of services is central to user choice. This study used systematic review methods to synthesise evidence in three main areas: (i) how people with LTC or disabilities and their family carers find and access information about the quality of services; (ii) how quality information is used in decision-making; and (iii) what type of quality information is most useful. Quality information was defined broadly and could include formal quality reports (e.g. inspection reports, report cards, etc.), information about the characteristics of a service or provider (e.g. number and qualifications of staff, facilities, etc.) and informal reports about quality (e.g. personal experience, etc.). Literature searches were carried out using electronic databases in January 2012. Thirteen papers reporting findings from empirical studies published between 2001 and 2012 were included in the review. The majority of papers (n = 9) had a qualitative design. The analysis highlighted the use of multiple sources of information in decision-making about services and in particular the importance of informal sources and extended social networks in accessing information. There is limited awareness and use of 'official' and online information sources. Service users or family carers place greater emphasis on general information and structural indicators. Clinical or quality-of-life outcomes are often difficult to interpret and apply. Trust emerged a key issue in relation to quality information. Experiential and subjective information is highly valued and trusted. Various barriers to the effective use of quality information in making choices about services are identified. Implications for policy and future research are discussed. © 2014

Objective To assess the quality of information provided to consumers by websites marketing medical home diagnostic tests. Design A cross-sectional analysis of a database developed from searching targeted websites. Setting Data sources were websites written in English which marketed medical home diagnostic tests. Main outcome measures A meta-search engine was used to identify the first 20 citations for each type of home diagnostic medical test. Relevant websites limited to those written in English were reviewed independently and in triplicate, with disputes resolved by two further reviewers. Information on the quality of these sites was extracted using a pre-piloted performer. Results 168 websites were suitable for inclusion in the review. The quality of these sites showed marked variation. Only 24 of 168 (14.2%) complied with at least three-quarters of the quality items and just over half (95 of 168, 56.5%) reported official approval or certification of the test. Information on accuracy of the test marketed was reported by 87 of 168 (51.7%) websites, with 15 of 168 (8.9%) providing a scientific reference. Instructions for use of the product were found in 97 of 168 (57.9%). However, the course of action to be taken after obtaining the test result was stated in only 63 of 168 (37.5%) for a positive result and 43 of 168 (25.5%) for a negative result. Conclusions The quality of information posted on commercial websites marketing home tests online is unsatisfactory and potentially misleading for consumers. PMID:18263912

Quality analysis of patient information on surgical treatment of haemorrhoids on the internet.

Yeung, T M; D'Souza, N D

2013-07-01

Haemorrhoids are the most common benign condition seen by colorectal surgeons. At clinic appointments, advice given about lifestyle modification or surgical interventions may not be understood fully by patients. Patients may use the internet for further research into their condition. However, the quality of such information has not been investigated before. This study assessed the quality of patient information on surgical treatment of haemorrhoids on the internet. Four searches were carried out using the search terms 'surgery for haemorrhoids' and 'surgery for piles' on two search engines (Google and Yahoo). The first 50 results for each search were assessed. Sites were evaluated using the DISCERN instrument. In total, 200 websites were assessed, of which 144 fulfilled the inclusion criteria. Of these, 63 (44%) were sponsored by herbal remedies for haemorrhoids. Eighty-nine (62%) mentioned conservative treatment options but eleven (8%) did not include surgery in their treatment options. Only 38 sites (27%) mentioned recurrence of haemorrhoids following surgery and 28 sites (20%) did not list any complications. Overall, 19 websites (14%) were judged as being of high quality, 66 (45%) as moderate quality and 58 (40%) as low quality. The quality of information on the internet is highly variable and a significant proportion of websites assessed are poor. The majority of websites are sponsored by private companies selling alternative treatments for haemorrhoids. Clinicians should be prepared to advise their patients which websites can provide high-quality information on the surgical treatment of haemorrhoids.

Information and Communication Technologies (ICTs) are means to handle information, streamline communication, and contribute to patient care. This article describes the incorporation of Information and Communication Technologies in primary care and its association with quality, based on the Brazilian National Program for the Improvement of Access and Quality in Primary Care (PMAQ in portuguese). This was a cross-sectional study with 17,053 teams. An Index of Incorporation of ICTs was created, which included: information infrastructure, systems, and utilization. Regression analysis was used to assess associations. Only 13.5% of the teams had a high degree of ICTs. The strongest association was seen in the utilization of information. ICTs can contribute to improving quality of primary care.

This purpose of this paper is to introduce the status of the Asan Medical Center (AMC) medical information system with respect to healthcare quality improvement. Asan Medical Information System (AMIS) is projected to become a completely electronic and digital information hospital. AMIS has played a role in improving the health care quality based on the following measures: safety, effectiveness, patient-centeredness, timeliness, efficiency, privacy, and security. AMIS CONSISTED OF SEVERAL DISTINCTIVE SYSTEMS: order communication system, electronic medical record, picture archiving communication system, clinical research information system, data warehouse, enterprise resource planning, IT service management system, and disaster recovery system. The most distinctive features of AMIS were the high alert-medication recognition & management system, the integrated and severity stratified alert system, the integrated patient monitoring system, the perioperative diabetic care monitoring and support system, and the clinical indicator management system. AMIS provides IT services for AMC, 7 affiliated hospitals and over 5,000 partners clinics, and was developed to improve healthcare services. The current challenge of AMIS is standard and interoperability. A global health IT strategy is needed to get through the current challenges and to provide new services as needed.

The Internet has provided great opportunities for disseminating both accurate and inaccurate health information. Therefore, the quality of information is considered as a widespread concern affecting the human life. Despite the increasingly substantial growth in the number of users, Persian health websites and the proportion of internet-using patients, little is known about the quality of Persian medical and health websites. The current study aimed to first assess the quality, popularity and importance of websites providing Persian health-related information, and second to evaluate the correlation of the popularity and importance ranking with quality score on the Internet. The sample websites were identified by entering the health-related keywords into four most popular search engines of Iranian users based on the Alexa ranking at the time of study. Each selected website was assessed using three qualified tools including the Bomba and Land Index, Google PageRank and the Alexa ranking. The evaluated sites characteristics (ownership structure, database, scope and objective) really did not have an effect on the Alexa traffic global rank, Alexa traffic rank in Iran, Google PageRank and Bomba total score. Most websites (78.9 percent, n = 56) were in the moderate category (8 ≤ x ≤ 11.99) based on their quality levels. There was no statistically significant association between Google PageRank with Bomba index variables and Alexa traffic global rank (P > 0.05). The Persian health websites had better Bomba quality scores in availability and usability guidelines as compared to other guidelines. The Google PageRank did not properly reflect the real quality of evaluated websites and Internet users seeking online health information should not merely rely on it for any kind of prejudgment regarding Persian health websites. However, they can use Iran Alexa rank as a primary filtering tool of these websites. Therefore, designing search engines dedicated to explore accredited

Legal issues concerning electronic health information: privacy, quality, and liability.

PubMed

Hodge, J G; Gostin, L O; Jacobson, P D

1999-10-20

Personally identifiable health information about individuals and general medical information is increasingly available in electronic form in health databases and through online networks. The proliferation of electronic data within the modern health information infrastructure presents significant benefits for medical providers and patients, including enhanced patient autonomy, improved clinical treatment, advances in health research and public health surveillance, and modern security techniques. However, it also presents new legal challenges in 3 interconnected areas: privacy of identifiable health information, reliability and quality of health data, and tortbased liability. Protecting health information privacy (by giving individuals control over health data without severely restricting warranted communal uses) directly improves the quality and reliability of health data (by encouraging individual uses of health services and communal uses of data), which diminishes tort-based liabilities (by reducing instances of medical malpractice or privacy invasions through improvements in the delivery of health care services resulting in part from better quality and reliability of clinical and research data). Following an analysis of the interconnectivity of these 3 areas and discussing existing and proposed health information privacy laws, recommendations for legal reform concerning health information privacy are presented. These include (1) recognizing identifiable health information as highly sensitive, (2) providing privacy safeguards based on fair information practices, (3) empowering patients with information and rights to consent to disclosure (4) limiting disclosures of health data absent consent, (5) incorporating industry-wide security protections, (6) establishing a national data protection authority, and (7) providing a national minimal level of privacy protections.

Background Many men lack knowledge about male infertility, and this may have consequences for their reproductive and general health. Men may prefer to seek health information online, but these sources of information vary in quality. Objective The objective of this study is to determine if online sources of information regarding male infertility are readable, suitable, and of appropriate quality for Internet users in the general population. Methods This study used a cross-sectional design to evaluate online sources resulting from search engine queries. The following categories of websites were considered: (1) Canadian fertility clinics, (2) North American organizations related to fertility, and (3) the first 20 results of Google searches using the terms “male infertility” and “male fertility preservation” set to the search locations worldwide, English Canada, and French Canada. Websites that met inclusion criteria (N=85) were assessed using readability indices, the Suitability Assessment of Materials (SAM), and the DISCERN tool. The associations between website affiliation (government, university/medical, non-profit organization, commercial/corporate, private practice) and Google placement to readability, suitability, and quality were also examined. Results None of the sampled websites met recommended levels of readability. Across all websites, the mean SAM score for suitability was 45.37% (SD 11.21), or “adequate”, while the DISCERN mean score for quality was 43.19 (SD 10.46) or “fair”. Websites that placed higher in Google obtained a higher overall score for quality with an r (58) value of -.328 and a P value of .012, but this position was not related to readability or suitability. In addition, 20% of fertility clinic websites did not include fertility information for men. Conclusions There is a lack of high quality online sources of information on male fertility.

2017-01-01

Background China has a large population with cardiovascular disease (CVD) that requires extensive self-management. Mobile health (mHealth) apps may be a useful tool for CVD self-management. Little is currently known about the types and quality of health information provided in Chinese CVD mobile apps and whether app functions are conducive to promoting CVD self-management. Objective We undertook a systematic review to evaluate the types and quality of health information provided in Chinese CVD mobile apps and interactive app functions for promoting CVD self-management. Methods Mobile apps targeting end users in China with CVD conditions were selected in February 2017 through a multi-stage process. Three frameworks were used to evaluate the selected apps: (1) types of health information offered were assessed using our Health Information Wants framework, which encompasses 7 types of information; (2) quality of information provided in the apps was assessed using the 11 guidelines recommended by the National Library of Medicine of the National Institutes of Health; and (3) types of interactive app functions for CVD self-management were assessed using a 15-item framework adapted from the literature, including our own prior work. Results Of 578 apps identified, 82 were eligible for final review. Among these, information about self-care (67/82, 82%) and information specifically regarding CVD (63/82, 77%) were the most common types of information provided, while information about health care providers (22/82, 27%) and laboratory tests (5/82, 6%) were least common. The most common indicators of information quality were the revealing of apps’ providers (82/82, 100%) and purpose (82/82, 100%), while the least common quality indicators were the revealing of how apps’ information was selected (1/82, 1%) and app sponsorship (0/82, 0%). The most common interactive functions for CVD self-management were those that enabled user interaction with the app provider (57/82, 70%) and

A cross section of Web sites accessible to the general public was surveyed. To evaluate the quality and accuracy of information on scoliosis that a patient might access on the Internet. The Internet is a rapidly expanding communications network with an estimated 765 million users worldwide by the year 2005. Medical information is one of the most common sources of inquires on the Web. More than 100 million Americans accessed the Internet for medical information in the year 2000. Undoubtedly, the use of the Internet for patient information needs will continue to expand as Internet access becomes more readily available. This expansion combined with the Internet's poorly regulated format can lead to problems in the quality of information available. Since the Internet operates on a global scale, implementing and enforcing standards have been difficult. The largely uncontrolled information can potentially negatively influence consumer health outcomes. To identify potential sites, five search engines were selected and the word "scoliosis" was entered into each search engine. A total of 50 Web sites were chosen for review. Each Web site was evaluated according to the type of Web site, quality content, and informational accuracy by three board-certified academic orthopedic surgeons, fellowship trained in spinal surgery, who each has been in practice for a minimum of 8 years. Each Web site was categorized as academic, commercial, physician, nonphysician health professional, and unidentified. In addition, each Web site was evaluated according to scoliosis-specific content using a point value system of 32 disease-specific key words pertinent to the care of scoliosis on an ordinal scale. A list of these words is given. Point values were given for the use of key words related to disease summary, classifications, treatment options, and complications. The accuracy of the individual Web site was evaluated by each spine surgeon using a scale of 1 to 4. A score of 1 represents that

Objective. The aim of this study was to appraise the quality of information on BC available at websites run by organizations in Africa. Methods. Three searches were conducted using Google search engine to generate a list of websites. The identified websites were assessed using European Commission (EC) quality criteria for health-related websites, which comprises different assessment areas including, completeness, transparency and honesty, authority, privacy and data protection, updating of information, accountability, and accessibility. Results. Thirteen (13) websites were included in the evaluation. Majority of the websites evaluated had low scores on the completeness and transparency of their websites. Scores on accessibility were however moderate and high for most of the websites. Breast cancer-specific organizations provided the highest quality information, particularly in terms of completeness. The overall lowest and highest quality scores were 9 and 43 out of 63, respectively, and 77% of the included websites scored less than 50% of the total quality score. Conclusion. This review has provided evidence of inadequate and inaccurate BC information provided by some cancer organizations in Africa. Considerable effort is required to make BC information on the Internet a valuable and up-to-date source for both professionals and patients. PMID:28168059

Dietary modification is critical in the self-management of chronic kidney disease. The present study describes the accuracy, quality and health literacy demand of renal diet information for adults with kidney disease obtained from the Internet and YouTube (www.youtube.com). A comprehensive content analysis was undertaken in April and July 2015 of 254 eligible websites and 161 YouTube videos. The accuracy of the renal diet information was evaluated by comparing the key messages with relevant evidence-based guidelines for the dietary management of people with kidney disease. The DISCERN tool (www.discern.org.uk) was used to evaluate the quality of the material. Health literacy demand was evaluated using the Patient Education Material Assessment Tool (www.ahrq.gov/professionals/prevention-chronic-care/improve/self-mgmt/pemat/index.html) and seven validated readability calculators. The most frequent renal diet topic found online was generic dietary information for people with chronic kidney disease. The proportion of renal diet information obtained from websites that was accurate was 73%. However, this information was mostly of poor quality with extensive shortcomings, difficult to action and written with a high health literacy demand. By contrast, renal diet information available from YouTube was highly understandable and actionable, although only 18% of the videos were accurate, and a large proportion were of poor quality with extensive shortcomings. The most frequent authors of accurate, good quality, understandable, material were government bodies, dietitians, academic institutions and medical organisations. Renal diet information found online that is written by government bodies, dietitians, academic institutions and medical organisations is recommended. Further work is required to improve the quality and, most importantly, the actionability of renal diet information found online. © 2017 The British Dietetic Association Ltd.

Quality analysis of patient information on surgical treatment of haemorrhoids on the internet

D’Souza, ND

2013-01-01

Introduction Haemorrhoids are the most common benign condition seen by colorectal surgeons. At clinic appointments, advice given about lifestyle modification or surgical interventions may not be understood fully by patients. Patients may use the internet for further research into their condition. However, the quality of such information has not been investigated before. This study assessed the quality of patient information on surgical treatment of haemorrhoids on the internet. Methods Four searches were carried out using the search terms ‘surgery for haemorrhoids’ and ‘surgery for piles’ on two search engines (Google and Yahoo). The first 50 results for each search were assessed. Sites were evaluated using the DISCERN instrument. Results In total, 200 websites were assessed, of which 144 fulfilled the inclusion criteria. Of these, 63 (44%) were sponsored by herbal remedies for haemorrhoids. Eighty-nine (62%) mentioned conservative treatment options but eleven (8%) did not include surgery in their treatment options. Only 38 sites (27%) mentioned recurrence of haemorrhoids following surgery and 28 sites (20%) did not list any complications. Overall, 19 websites (14%) were judged as being of high quality, 66 (45%) as moderate quality and 58 (40%) as low quality. Conclusions The quality of information on the internet is highly variable and a significant proportion of websites assessed are poor. The majority of websites are sponsored by private companies selling alternative treatments for haemorrhoids. Clinicians should be prepared to advise their patients which websites can provide high-quality information on the surgical treatment of haemorrhoids. PMID:23838496

[Validation of a questionnaire to assess the quality of health information in Argentinian newspapers].

The daily press is an important source of health information and may influence health care utilization. However, medical reports published in newspapers from developed countries have shown a poor quality. The reliability of the questionnaire Index of Scientific Quality was evaluated by using it to measure the scientific quality of health information published by Argentinian newspapers between 2000 and 2002. It assessed the readability of the texts in grade levels and explored the relationship between quality and other factors. The Spanish adaptation of the instrument consisted in translation, back-traslation and pilot study. The reliability was assessed by applying the instrument to newspaper articles with more than 300 words that discussed therapy, diagnosis, prevention, lifestyle effects, and hazardous exposure. Two physicians independently graded 129 articles. Inter-observer and intra-observer concordance was quantified for each item with the intra-class correlation coefficient (CI95%). To measure scientific quality, a randomized sample of 210 articles was assessed. Each received a mark that ranged from 0 to 100. Readability was determined by the FRY graph method. The relationship between quality and other variables was explored with multiple linear regression analysis. The inter-rater concordance varied between 0.48 (0.34-0.61) and 0.67 (0.56-0.75). Intra-rater concordance varied from 0.51 (0.37-0.63) to 0.95 (0.93-0.96). The internal consistency (Cronbach's alpha) was 0.88. The quality-of-health-information was rated at 25 points (16.7, 33.3) [median (intercuartil range)]. The reading level was assessed to be at the 10.4 grade (10.2-10.6) [mean (CI 95%)]. Quality of the health information was greatly deficient; however, no specific factors were related with quality. Readability was probably a key barrier for access to the health information.

Requirement analysis, design, implementation, evaluation, use, and maintenance of semantically interoperable Health Information Systems (HIS) have to be based on eHealth standards. HIS-DF is a comprehensive approach for HIS architectural development based on standard information models and vocabulary. The empirical validity of HIS-DF has not been demonstrated so far. Through an empirical experiment, the paper demonstrates that using HIS-DF and HL7 information models, semantic quality of HIS architecture can be improved, compared to architectures developed using traditional RUP process. Semantic quality of the architecture has been measured in terms of model's completeness and validity metrics. The experimental results demonstrated an increased completeness of 14.38% and an increased validity of 16.63% when using the HIS-DF and HL7 information models in a sample HIS development project. Quality assurance of the system architecture in earlier stages of HIS development presumes an increased quality of final HIS systems, which supposes an indirect impact on patient care.

Health Information Technology in Healthcare Quality and Patient Safety: Literature Review.

PubMed

Feldman, Sue S; Buchalter, Scott; Hayes, Leslie W

2018-06-04

The area of healthcare quality and patient safety is starting to use health information technology to prevent reportable events, identify them before they become issues, and act on events that are thought to be unavoidable. As healthcare organizations begin to explore the use of health information technology in this realm, it is often unclear where fiscal and human efforts should be focused. The purpose of this study was to provide a foundation for understanding where to focus health information technology fiscal and human resources as well as expectations for the use of health information technology in healthcare quality and patient safety. A literature review was conducted to identify peer-reviewed publications reporting on the actual use of health information technology in healthcare quality and patient safety. Inductive thematic analysis with open coding was used to categorize a total of 41 studies. Three pre-set categories were used: prevention, identification, and action. Three additional categories were formed through coding: challenges, outcomes, and location. This study identifies five main categories across seven study settings. A majority of the studies used health IT for identification and prevention of healthcare quality and patient safety issues. In this realm, alerts, clinical decision support, and customized health IT solutions were most often implemented. Implementation, interface design, and culture were most often noted as challenges. This study provides valuable information as organizations determine where they stand to get the most "bang for their buck" relative to health IT for quality and patient safety. Knowing what implementations are being effectivity used by other organizations helps with fiscal and human resource planning as well as managing expectations relative to cost, scope, and outcomes. The findings from this scan of the literature suggest that having organizational champion leaders that can shepherd implementation, impact culture

The quality of internet sites providing information relating to oral cancer.

López-Jornet, Pia; Camacho-Alonso, Fabio

2009-09-01

To determine the quality of the information available on the internet in relation to oral cancer. Sites were identified using two search engines (Google and Yahoo), and the search term "oral cancer". The first 100 consecutive sites in each search were visited and classified. The websites were evaluated for quality of content by using the validated DISCERN rating instrument and the JAMA benchmarks; the existence of the Health on the Net (HON) seal was also registered. The Google search yielded 25,70,000 sites for oral cancer, while Yahoo yielded 6,99,00,000. We reviewed 29 Google websites and 22 Yahoo websites. Based on the JAMA benchmarks, only two sites (6.9%) met the four criteria in the Google search, versus a single site (4.5%) in the Yahoo search. As regards the DISCERN instrument, no site obtained the maximum score. Moreover, in the Google search, 72.5% of the sites had serious deficiencies, versus 68.2% of the Yahoo sites. Lastly, eight of the Google sites (27.6%) and four of the Yahoo sites (18.2%) presented the HON seal. The quality of the healthcare information related to oral cancer on the internet is poor. There is a need to be vigilant about the quality of information found on the internet.

Information Quality Challenges of Patient-Generated Data in Clinical Practice

PubMed Central

West, Peter; Van Kleek, Max; Giordano, Richard; Weal, Mark; Shadbolt, Nigel

2017-01-01

A characteristic trend of digital health has been the dramatic increase in patient-generated data being presented to clinicians, which follows from the increased ubiquity of self-tracking practices by individuals, driven, in turn, by the proliferation of self-tracking tools and technologies. Such tools not only make self-tracking easier but also potentially more reliable by automating data collection, curation, and storage. While self-tracking practices themselves have been studied extensively in human–computer interaction literature, little work has yet looked at whether these patient-generated data might be able to support clinical processes, such as providing evidence for diagnoses, treatment monitoring, or postprocedure recovery, and how we can define information quality with respect to self-tracked data. In this article, we present the results of a literature review of empirical studies of self-tracking tools, in which we identify how clinicians perceive quality of information from such tools. In the studies, clinicians perceive several characteristics of information quality relating to accuracy and reliability, completeness, context, patient motivation, and representation. We discuss the issues these present in admitting self-tracked data as evidence for clinical decisions. PMID:29209601

Informed consent forms are very important in the process of medical information. The aim of this study is to design reliable formal quality criteria of these documents and their application in the evaluation of those used in the hospitals of a regional health service. Criteria have been designed from the analysis of existing regulations, previous studies and consultation with key experts. The interobserver concordance was assessed using the kappa index. Criteria evaluation was performed on 1425 documents of 9 hospitals. A total of 19 criteria used in the evaluation of the quality of informed consent forms have been obtained. Kappa values were higher than 0,60 in 17 of them and higher than 0,52 in the other 2. The average number of defects per document was 7.6, with a high-low ratio among hospitals of 1.84. More than 90% of the documents had defects in the information on consequences and contraindications, and in about 90% it did not mention the copy to the patient. More than 60% did not comply with stating the purpose of the procedure, a statement of having understood and clarified doubts, and the treatment options. A tool has been obtained to reliably assess the formal quality of the informed consent forms. The documents assessed have a wide margin for improvement related to giving a copy to the patient, and some aspects of the specific information that patients should receive. Copyright © 2012 SECA.

Davaris, Myles; Barnett, Stephen; Abouassaly, Robert

2017-01-01

Background Previous data suggest that quality of Internet information regarding surgical conditions and their treatments is variable. However, no comprehensive analysis of website quality exists for thoracic surgery. Objective The aim of this study was to quantify website quality in a multilingual setting using an international standard for assessment. Methods Health On the Net (HON) principles may be applied to websites using an automated toolbar function. We used the English, French, Spanish, and German Google search engines to identify 12,000 websites using keywords related to thoracic conditions and procedures. The first 150 websites returned by each keyword in each language were examined. We compared website quality to assess for tertile (is the quality better in first, second, or third 50 websites returned) and language differences. A further analysis of the English site types was undertaken performing a comparative analysis of website provider types. Results Overall, there are a considerable number of websites devoted to thoracic surgery: “lung cancer” returned over 150 million websites. About 7.85% (940/11,967) of websites are HON-accredited with differences by search term (P<.001) and tertiles (P<.001) of the first 150 websites, but not between languages. Oncological keywords regarding conditions and procedures were found to return a higher percentage of HON-accreditation. The percentage of HON-accredited sites was similar across all four languages (P=.77). In general, the first tertile contained a higher percentage of HON-accredited sites for every keyword. Conclusions Clinicians should appreciate the lack of validation of the majority of thoracic websites, with discrepancies in quality and number of websites across conditions and procedures. These differences appear similar regardless of language. An opportunity exists for clinicians to participate in the development of informative, ethical, and reliable health websites on the Internet and direct

2013-01-01

This study aimed to assess the quality and accuracy of nutrition information about cancer prevention available on the Web. The keywords 'nutrition  +  diet  +  cancer  +  prevention' were submitted to the Google search engine. Out of 400 websites evaluated, 100 met the inclusion and exclusion criteria and were selected as the sample for the assessment of quality and accuracy. Overall, 54% of the studied websites had low quality, 48 and 57% had no author's name or information, respectively, 100% were not updated within 1 month during the study period and 86% did not have the Health on the Net seal. When the websites were assessed for readability using the Flesch Reading Ease test, nearly 44% of the websites were categorised as 'quite difficult'. With regard to accuracy, 91% of the websites did not precisely follow the latest WCRF/AICR 2007 recommendation. The quality scores correlated significantly with the accuracy scores (r  =  0.250, p  <  0.05). Professional websites (n  =  22) had the highest mean quality scores, whereas government websites (n  =  2) had the highest mean accuracy scores. The quality of the websites selected in this study was not satisfactory, and there is great concern about the accuracy of the information being disseminated.

High quality data and effective data quality assessment are required for accurately evaluating the impact of public health interventions and measuring public health outcomes. Data, data use, and data collection process, as the three dimensions of data quality, all need to be assessed for overall data quality assessment. We reviewed current data quality assessment methods. The relevant study was identified in major databases and well-known institutional websites. We found the dimension of data was most frequently assessed. Completeness, accuracy, and timeliness were the three most-used attributes among a total of 49 attributes of data quality. The major quantitative assessment methods were descriptive surveys and data audits, whereas the common qualitative assessment methods were interview and documentation review. The limitations of the reviewed studies included inattentiveness to data use and data collection process, inconsistency in the definition of attributes of data quality, failure to address data users' concerns and a lack of systematic procedures in data quality assessment. This review study is limited by the coverage of the databases and the breadth of public health information systems. Further research could develop consistent data quality definitions and attributes. More research efforts should be given to assess the quality of data use and the quality of data collection process.

LANDSAT-4 thematic mapper (TM) and multispectral scanner (MSS) data were analyzed to obtain information on data quality and information content. Geometric evaluations were performed to test band-to-band registration accuracy. Thematic mapper overall system resolution was evaluated using scene objects which demonstrated sharp high contrast edge responses. Radiometric evaluation included detector relative calibration, effects of resampling, and coherent noise effects. Information content evaluation was carried out using clustering, principal components, transformed divergence separability measure, and supervised classifiers on test data. A detailed spectral class analysis (multispectral classification) was carried out to compare the information content of the MSS and TM for a large number of scene classes. A temperature-mapping experiment was carried out for a cooling pond to test the quality of thermal-band calibration. Overall TM data quality is very good. The MSS data are noisier than previous LANDSAT results.

Chinese Cardiovascular Disease Mobile Apps' Information Types, Information Quality, and Interactive Functions for Self-Management: Systematic Review.

Xie, Bo; Su, Zhaohui; Zhang, Wenhui; Cai, Run

2017-12-14

China has a large population with cardiovascular disease (CVD) that requires extensive self-management. Mobile health (mHealth) apps may be a useful tool for CVD self-management. Little is currently known about the types and quality of health information provided in Chinese CVD mobile apps and whether app functions are conducive to promoting CVD self-management. We undertook a systematic review to evaluate the types and quality of health information provided in Chinese CVD mobile apps and interactive app functions for promoting CVD self-management. Mobile apps targeting end users in China with CVD conditions were selected in February 2017 through a multi-stage process. Three frameworks were used to evaluate the selected apps: (1) types of health information offered were assessed using our Health Information Wants framework, which encompasses 7 types of information; (2) quality of information provided in the apps was assessed using the 11 guidelines recommended by the National Library of Medicine of the National Institutes of Health; and (3) types of interactive app functions for CVD self-management were assessed using a 15-item framework adapted from the literature, including our own prior work. Of 578 apps identified, 82 were eligible for final review. Among these, information about self-care (67/82, 82%) and information specifically regarding CVD (63/82, 77%) were the most common types of information provided, while information about health care providers (22/82, 27%) and laboratory tests (5/82, 6%) were least common. The most common indicators of information quality were the revealing of apps' providers (82/82, 100%) and purpose (82/82, 100%), while the least common quality indicators were the revealing of how apps' information was selected (1/82, 1%) and app sponsorship (0/82, 0%). The most common interactive functions for CVD self-management were those that enabled user interaction with the app provider (57/82, 70%) and with health care providers (36/82, 44

The goal set by the French highest national authorities in the 2014-2019 Cancer Plan is to "heal more sick persons by promoting early diagnosis through screening". Screening requires information. Nowadays, Internet allows for access to information "in one click". The aim of our study was to evaluate the quality of information found on the Internet. Several sites dedicated to oral cavity cancer screening were selected on Google. The quality of health information found in these sites was evaluated by the DISCERN questionnaire. The quality of decision support provided by the sites was evaluated by the IPDAS checklist. Twenty-seven sites were selected. The average DISCERN score was 25.1/75 (15/75 to 40/75). Eighteen sites (66.6%) had very poor, 8 sites (29.6%) had poor and 1 site had average information quality. IPDAS scores ranged from 11.1 to 38.1. Eight sites (29.6%) had less than 20%, 14 sites (51.9%) had between 20 and 30% and 5 sites (18.5%) had 30% or more validated criteria. No site achieved the pass mark. The quality of general public French-speaking website dedicated to oral cancer detection is very bad. The role of health professionals such as general practitioners and head and neck surgeons, remains essential. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

The quality of mental health information commonly searched for on the Internet.

Grohol, John M; Slimowicz, Joseph; Granda, Rebecca

2014-04-01

Previous research has reviewed the quality of online information related to specific mental disorders. Yet, no comprehensive study has been conducted on the overall quality of mental health information searched for online. This study examined the first 20 search results of two popular search engines-Google and Bing-for 11 common mental health terms. They were analyzed using the DISCERN instrument, an adaptation of the Depression Website Content Checklist (ADWCC), Flesch Reading Ease and Flesch-Kincaid Grade Level readability measures, HONCode badge display, and commercial status, resulting in an analysis of 440 web pages. Quality of Web site results varied based on type of disorder examined, with higher quality Web sites found for schizophrenia, bipolar disorder, and dysthymia, and lower quality ratings for phobia, anxiety, and panic disorder Web sites. Of the total Web sites analyzed, 67.5% had good or better quality content. Nearly one-third of the search results produced Web sites from three entities: WebMD, Wikipedia, and the Mayo Clinic. The mean Flesch Reading Ease score was 41.21, and the mean Flesch-Kincaid Grade Level score was 11.68. The presence of the HONCode badge and noncommercial status was found to have a small correlation with Web site quality, and Web sites displaying the HONCode badge and commercial sites had lower readability scores. Popular search engines appear to offer generally reliable results pointing to mostly good or better quality mental health Web sites. However, additional work is needed to make these sites more readable.

Information quantity and quality affect the realistic accuracy of personality judgment.

PubMed

Letzring, Tera D; Wells, Shannon M; Funder, David C

2006-07-01

Triads of unacquainted college students interacted in 1 of 5 experimental conditions that manipulated information quantity (amount of information) and information quality (relevance of information to personality), and they then made judgments of each others' personalities. To determine accuracy, the authors compared the ratings of each judge to a broad-based accuracy criterion composed of personality ratings from 3 types of knowledgeable informants (the self, real-life acquaintances, and clinician-interviewers). Results supported the hypothesis that information quantity and quality would be positively related to objective knowledge about the targets and realistic accuracy. Interjudge consensus and self-other agreement followed a similar pattern. These findings are consistent with expectations based on models of the process of accurate judgment (D. C. Funder, 1995, 1999) and consensus (D. A. Kenny, 1994). Copyright 2006 APA, all rights reserved.

Public reporting in health care: how do consumers use quality-of-care information? A systematic review.

PubMed

Faber, Marjan; Bosch, Marije; Wollersheim, Hub; Leatherman, Sheila; Grol, Richard

2009-01-01

One of the underlying goals of public reporting is to encourage the consumer to select health care providers or health plans that offer comparatively better quality-of-care. To review the weight consumers give to quality-of-care information in the process of choice, to summarize the effect of presentation formats, and to examine the impact of quality information on consumers' choice behavior. The evidence is organized in a theoretical consumer choice model. English language literature was searched in PubMed, the Cochrane Clinical Trial, and the EPOC Databases (January 1990-January 2008). Study selection was limited to randomized controlled trails, controlled before-after trials or interrupted time series. Included interventions focused on choice behavior of consumers in health care settings. Outcome measures referred to one of the steps in a consumer choice model. The quality of the study design was rated, and studies with low quality ratings were excluded. All 14 included studies examine quality information, usually CAHPS, with respect to its impact on the consumer's choice of health plans. Easy-to-read presentation formats and explanatory messages improve knowledge about and attitude towards the use of quality information; however, the weight given to quality information depends on other features, including free provider choice and costs. In real-world settings, having seen quality information is a strong determinant for choosing higher quality-rated health plans. This review contributes to an understanding of consumer choice behavior in health care settings. The small number of included studies limits the strength of our conclusions.

2010-09-01

The Internet provides great opportunities for patient healthcare education, but poses risks that inaccurate, outdated or harmful information will be disseminated. Our objective was determine the quality of the information available on the internet in relation to oral leukoplakia. Sites were identified using 3 search engines (Google, Yahoo and MSN), and the search term oral leukoplakia. The first 100 consecutive sites in each search were visited and classified. The websites were evaluated for quality of content by using the validated DISCERN rating instrument and the JAMA benchmarks; the existence of the Health on the Net (HON) seal was also registered. The Google search yielded 54.300 sites for oral leukoplakia, while Yahoo yielded 243.000 and MSN 103.000. We reviewed 21 Google websites, 20 Yahoo websites and 19 MSN. Based on the JAMA benchmarks, only 4 sites (19.1%) met the four criteria in the Google search, versus 2 sites (10%) in the Yahoo and 5 (26.3%) in MSN. With the DISCERN instrument, no site obtained the maximum score, with Google 13 sites presented serious deficiencies (61.9%), in the Yahoo search 14 (70%), and in MSN 15 (78.9%). Lastly, 4 of the Google sites (19.1%), four of the Yahoo sites (20%) and 2 (10.5%) MSN sites presented the HON seal. The quality of the health care information related to oral leukoplakia on the internet is poor.

A recurring demand in working with satellite-based earth science data records is the need to apply data quality information. Such quality information is often contained within the data files as an array of "flags", but can also be represented by more complex quality descriptions such as combinations of bit flags, or even other ancillary variables that can be applied as thresholds to the geophysical variable of interest. For example, with Level 2 granules from the Group for High Resolution Sea Surface Temperature (GHRSST) project up to 6 independent variables could be used to screen the sea surface temperature measurements on a pixel-by-pixel basis. Quality screening of Level 3 data from the Soil Moisture Active Passive (SMAP) instrument can be become even more complex, involving 161 unique bit states or conditions a user can screen for. The application of quality information is often a laborious process for the user until they understand the implications of all the flags and bit conditions, and requires iterative approaches using custom software. The Virtual Quality Screening Service, a NASA ACCESS project, is addressing these issues and concerns. The project has developed an infrastructure to expose, apply, and extract quality screening information building off known and proven NASA components for data extraction and subset-by-value, data discovery, and exposure to the user of granule-based quality information. Further sharing of results through well-defined URLs and web service specifications has also been implemented. The presentation will focus on overall description of the technologies and informatics principals employed by the project. Examples of implementations of the end-to-end web service for quality screening with GHRSST and SMAP granules will be demonstrated.

Information Quality in Regulatory Decision Making: Peer Review versus Good Laboratory Practice.

PubMed

McCarty, Lynn S; Borgert, Christopher J; Mihaich, Ellen M

2012-07-01

There is an ongoing discussion on the provenance of toxicity testing data regarding how best to ensure its validity and credibility. A central argument is whether journal peer-review procedures are superior to Good Laboratory Practice (GLP) standards employed for compliance with regulatory mandates. We sought to evaluate the rationale for regulatory decision making based on peer-review procedures versus GLP standards. We examined pertinent published literature regarding how scientific data quality and validity are evaluated for peer review, GLP compliance, and development of regulations. Some contend that peer review is a coherent, consistent evaluative procedure providing quality control for experimental data generation, analysis, and reporting sufficient to reliably establish relative merit, whereas GLP is seen as merely a tracking process designed to thwart investigator corruption. This view is not supported by published analyses pointing to subjectivity and variability in peer-review processes. Although GLP is not designed to establish relative merit, it is an internationally accepted quality assurance, quality control method for documenting experimental conduct and data. Neither process is completely sufficient for establishing relative scientific soundness. However, changes occurring both in peer-review processes and in regulatory guidance resulting in clearer, more transparent communication of scientific information point to an emerging convergence in ensuring information quality. The solution to determining relative merit lies in developing a well-documented, generally accepted weight-of-evidence scheme to evaluate both peer-reviewed and GLP information used in regulatory decision making where both merit and specific relevance inform the process.

Cauda equina syndrome: assessing the readability and quality of patient information on the Internet.

2014-05-01

A readability and quality control Internet-based study using recognized quality scoring systems. To assess the readability and quality of Internet information relating to cauda equina syndrome accessed through common search engines. Access to health-related Internet information has increased dramatically during the past decade. A significant proportion of this information has been demonstrated to be set at too high a level for general comprehension. Despite this, searching for health-related information is now the third most popular online activity. A total of 125 cauda equina syndrome Web sites were analyzed from the 5 most popular Internet search engines: Google, Bing, Yahoo, Ask, and AOL. Web site authorship was classified: academic, physician, medico-legal, commercial, or discussion/social media. Readability of each Web site was assessed using the Flesch Reading Ease score, the Flesch-Kincaid grade level, and the Gunning Fog Index. Quality was calculated using the DISCERN instrument and The Journal of the American Medical Association benchmark criteria. The presence of HON-code certification was also assessed. Fifty-two individual Web sites were identified and assessed. The majority of Web sites were academic or physician compiled (53.8%; 28/52); however, a significant minority of Web sites were medico-legal related (19.2%; 10/52). Just 13.5% (7/52) of Web sites were at or below the recommended sixth-grade readability level. HON-code certified Web sites achieved significantly greater DISCERN (P = 0.0006) and The Journal of the American Medical Association (P = 0.0002) scores. Internet information relating to cauda equina syndrome is of variable quality and largely set at an inappropriate readability level. Given this variability in quality, health care providers should direct patients to known sources of reliable, readable online information. Identification of reliable sources may be aided by known markers of quality such as HON-code certification.

Structured data quality reports to improve EHR data quality.

Taggart, Jane; Liaw, Siaw-Teng; Yu, Hairong

2015-12-01

To examine whether a structured data quality report (SDQR) and feedback sessions with practice principals and managers improve the quality of routinely collected data in EHRs. The intervention was conducted in four general practices participating in the Fairfield neighborhood electronic Practice Based Research Network (ePBRN). Data were extracted from their clinical information systems and summarised as a SDQR to guide feedback to practice principals and managers at 0, 4, 8 and 12 months. Data quality (DQ) metrics included completeness, correctness, consistency and duplication of patient records. Information on data recording practices, data quality improvement, and utility of SDQRs was collected at the feedback sessions at the practices. The main outcome measure was change in the recording of clinical information and level of meeting Royal Australian College of General Practice (RACGP) targets. Birth date was 100% and gender 99% complete at baseline and maintained. DQ of all variables measured improved significantly (p<0.01) over 12 months, but was not sufficient to comply with RACGP standards. Improvement was greatest with allergies. There was no significant change in duplicate records. SDQRs and feedback sessions support general practitioners and practice managers to focus on improving the recording of patient information. However, improved practice DQ, was not sufficient to meet RACGP targets. Randomised controlled studies are required to evaluate strategies to improve data quality and any associated improved safety and quality of care. Copyright © 2015 Elsevier Ireland Ltd.

Measuring quality of care: considering conceptual approaches to quality indicator development and evaluation.

PubMed

Stelfox, Henry T; Straus, Sharon E

2013-12-01

In this article, we describe one approach for developing and evaluating quality indicators. We focus on describing different conceptual approaches to quality indicator development, review one approach for developing quality indicators, outline how to evaluate quality indicators once developed, and discuss quality indicator maintenance. The key steps for developing quality indicators include specifying a clear goal for the indicators; using methodologies to incorporate evidence, expertise, and patient perspectives; and considering contextual factors and logistics of implementation. The Strategic Framework Board and the National Quality Measure Clearinghouse have developed criteria for evaluating quality indicators that complement traditional psychometric evaluations. Optimal strategies for quality indicator maintenance and dissemination have not been determined, but experiences with clinical guideline maintenance may be informative. For quality indicators to effectively guide quality improvement efforts, they must be developed, evaluated, maintained, and implemented using rigorous evidence-informed practices.

Health Information Exchange Readiness for Demonstrating Return on Investment and Quality of Care.

PubMed

Khurshid, Anjum; Diana, Mark L; Jain, Rahul

2015-01-01

To study the extent to which community health information exchanges (HIEs) deliver and measure return on investment (ROI) and improvements in the quality of care. We surveyed operational HIEs for their characteristics, information domains, impact on quality of care, and ROI. A 60 percent response rate was achieved. Two-thirds of respondents agreed that community HIEs demonstrated a positive ROI, while one-third had no opinion or disagreed. One-fourth or fewer respondents reported using various metrics to calculate ROI. Most respondents agreed that HIEs improve the quality of care, though several were not sure and were awaiting further evidence. Most respondents indicated that they did not deliver reports on quality measures (76 percent) and that data were not being used to measure quality performance of participating providers (73 percent). Respondents from most HIEs believe that the HIEs are demonstrating a positive ROI; however, a minority of them indicated they had used or will use specific metrics to calculate ROI. HIE representatives overwhelmingly reported that they believe the HIE activities improve the quality of healthcare delivered, but only a few are using data to evaluate provider performance or generate reports on quality measures. This study demonstrates the challenge faced by policy makers and healthcare organizations that are investing millions of dollars in HIEs that are believed to improve health outcomes and increase efficiency, but still need more time to develop the evidence to confirm that belief. Our study shows that calculating ROI for HIEs or their impact on quality of care remains a secondary priority for most HIEs. This finding raises serious questions for the sustained support of HIEs, both financially and as a policy lever, given the end of Health Information Technology for Economic and Clinical Health (HITECH) Act funding.

Although many patients use the internet to access health-related information, the quality and the reliability of the information is highly inconsistent. Periacetabular osteotomy (PAO) is one of the surgical procedures for hip dysplasia. However, medical information on PAO is limited on the internet. This study aims to evaluate the quality and reliability of information available on PAO on the internet in Japan. A web search was conducted on two search engines for the following terms: "hip osteotomy," "pelvic osteotomy," and "osteotomy for hip preservation" in Japanese. In total, we found 120 websites. To determine the quality and reliability of information on each website, we used the Health on the Net Foundation (HON) score, the Brief DISCERN score, and an osteotomy-specific content (OSC) score. After eliminating duplicate websites, we reviewed 49 unique websites. Only three websites (6.1%) had good reliability, as indicated by their HON scores. Twelve websites (24.4%) had good-quality information, as measured by their Brief DISCERN scores. As evaluated by their OSC scores, physician websites were found to be biased toward etiology and surgical indication and did not provide information on the complications of procedures. Non-physician websites were generally insufficient. The information about PAO on the internet is, therefore, unreliable and of poor-quality for Japanese patients.

Thoracic Surgery Information on the Internet: A Multilingual Quality Assessment.

2017-05-12

Previous data suggest that quality of Internet information regarding surgical conditions and their treatments is variable. However, no comprehensive analysis of website quality exists for thoracic surgery. The aim of this study was to quantify website quality in a multilingual setting using an international standard for assessment. Health On the Net (HON) principles may be applied to websites using an automated toolbar function. We used the English, French, Spanish, and German Google search engines to identify 12,000 websites using keywords related to thoracic conditions and procedures. The first 150 websites returned by each keyword in each language were examined. We compared website quality to assess for tertile (is the quality better in first, second, or third 50 websites returned) and language differences. A further analysis of the English site types was undertaken performing a comparative analysis of website provider types. Overall, there are a considerable number of websites devoted to thoracic surgery: "lung cancer" returned over 150 million websites. About 7.85% (940/11,967) of websites are HON-accredited with differences by search term (P<.001) and tertiles (P<.001) of the first 150 websites, but not between languages. Oncological keywords regarding conditions and procedures were found to return a higher percentage of HON-accreditation. The percentage of HON-accredited sites was similar across all four languages (P=.77). In general, the first tertile contained a higher percentage of HON-accredited sites for every keyword. Clinicians should appreciate the lack of validation of the majority of thoracic websites, with discrepancies in quality and number of websites across conditions and procedures. These differences appear similar regardless of language. An opportunity exists for clinicians to participate in the development of informative, ethical, and reliable health websites on the Internet and direct patients to them. ©Myles Davaris, Stephen Barnett

a Web Api and Web Application Development for Dissemination of Air Quality Information

Şahin, K.; Işıkdağ, U.

2017-11-01

Various studies have been carried out since 2005 under the leadership of Ministry of Environment and Urbanism of Turkey, in order to observe the quality of air in Turkey, to develop new policies and to develop a sustainable air quality management strategy. For this reason, a national air quality monitoring network has been developed providing air quality indices. By this network, the quality of the air has been continuously monitored and an important information system has been constructed in order to take precautions for preventing a dangerous situation. The biggest handicap in the network is the data access problem for instant and time series data acquisition and processing because of its proprietary structure. Currently, there is no service offered by the current air quality monitoring system for exchanging information with third party applications. Within the context of this work, a web service has been developed to enable location based querying of the current/past air quality data in Turkey. This web service is equipped with up-todate and widely preferred technologies. In other words, an architecture is chosen in which applications can easily integrate. In the second phase of the study, a web-based application was developed to test the developed web service and this testing application can perform location based acquisition of air-quality data. This makes it possible to easily carry out operations such as screening and examination of the area in the given time-frame which cannot be done with the national monitoring network.

2018-03-01

The purpose of this study was to examine nursing informatics competency and the quality of information processing among nurses in Jordan. The study was conducted in a large hospital with 380 registered nurses. The hospital introduced the electronic health record in 2010. The measures used in this study were personal and job characteristics, self-efficacy, Self-Assessment Nursing Informatics Competencies, and Health Information System Monitoring Questionnaire. The convenience sample consisted of 99 nurses who used the electronic health record for at least 3 months. The analysis showed that nine predictors explained 22% of the variance in the quality of information processing, whereas the statistically significant predictors were nursing informatics competency, clinical specialty, and years of nursing experience. There is a need for policies that advocate for every nurse to be educated in nursing informatics and the quality of information processing.

2018-02-01

The number of patients who seek health information on the internet is increasing. Rates are particularly high among lesbian, gay, bisexual, transgender and queer (LGBTQ) individuals, due to health care barriers. The aim of this study was to evaluate the quality and inclusivity of web-based information pertaining to LGBTQ family building. The first 100 US-based websites pertaining to LGBTQ family building were identified through a terminology-based internet search. After eliminating 45 websites, 55 websites were found to be eligible. The 2016 Website Information Reliability Evaluation Instrument (of the Office of Disease Prevention and Health Promotion, US Department of Health and Human Services) was used to analyse the quality of information on each website. Websites were analysed for inclusivity of important topics surrounding LGBTQ family building. A total of 46 websites (83.6%) belonged or were related to reproductive services and served as advertisements for their respective owners; nine websites (16.4%) belonged to third parties. No website met more than four of the six major reliability criteria, and 42 websites (76.4%) met only one or two of the six major reliability criteria. When inclusivity was considered, 29 websites (52.7%) mentioned options for transgender individuals and nine websites (16.4%) mentioned adoption. There is a lack of reliable web-based information for LGBTQ family building and a need for improvement in quality and scope. Improvements could lead to a shift in reproductive health care towards better inclusion of and catering to LGBTQ individuals.

A method and a technical solution for controlling the quality of production of liquid and gaseous media is proposed. It is also proposed to monitor harmful factors in production while ensuring safe working conditions. Initially, using the mathematical model of an ideal atmosphere, the projection to the horizontal surface of the observation trajectory is calculated. At the second stage, the horizontal projection of the observation trajectory in real conditions is measured. The quality of the medium is judged by the difference between the projections of observation trajectories. The technical result is presented in the form of a device allowing obtaining information about the quality of the medium under investigation.

Real-time dissemination of air quality information using data streams and Web technologies: linking air quality to health risks in urban areas.

2015-06-01

This article presents a new, original application of modern information and communication technology to provide effective real-time dissemination of air quality information and related health risks to the general public. Our on-line subsystem for urban real-time air quality monitoring is a crucial component of a more comprehensive integrated information system, which has been developed by the Institute for Medical Research and Occupational Health. It relies on a StreamInsight data stream management system and service-oriented architecture to process data streamed from seven monitoring stations across Zagreb. Parameters that are monitored include gases (NO, NO2, CO, O3, H2S, SO2, benzene, NH3), particulate matter (PM10 and PM2.5), and meteorological data (wind speed and direction, temperature and pressure). Streamed data are processed in real-time using complex continuous queries. They first go through automated validation, then hourly air quality index is calculated for every station, and a report sent to the Croatian Environment Agency. If the parameter values exceed the corresponding regulation limits for three consecutive hours, the web service generates an alert for population groups at risk. Coupled with the Common Air Quality Index model, our web application brings air pollution information closer to the general population and raises awareness about environmental and health issues. Soon we intend to expand the service to a mobile application that is being developed.

2012-01-01

To use a range of evaluation instruments to assess the content and quality of websites about temporomandibular disorders (TMD) and thereby provide guidance regarding the actual accuracy and comprehensiveness of the information of the sites. Sixty-seven websites resulting from an Internet search with the word "TMD" were evaluated using Journal of the American Medical Association (JAMA), DISCERN, and Health on the Net (HON) criteria, along with an evaluation method to assess the scientific quality of the website contents. Results were compared according to reviewer, website type, and presence of HON seal. One-way analysis of variance (ANOVA), Student t test, chi-square test, and Pearson correlation analysis were used as appropriate. The mean content, HON, and DISCERN scores were 38.9%, below 50%, and 53.9% of the maximum possible score, respectively. Fewer than 50% of the sites displayed the author or reference of the information according to the JAMA benchmarks criteria. Every evaluation criteria showed good agreement among reviewers. Commercial websites were the most common, while sites of nonprofit organizations showed the highest content scores. The overall quality was poor to moderate for all website types. Sites concerning TMD were poorly organized and maintained. Also, most sites contained insufficient or scientifically incorrect information that could have a negative effect on the treatment outcome and prognosis of TMD. Clinicians should guide patients to reputable sources of information that will enhance patient comprehension and better treatment outcomes.

2017-05-01

The incidence of hypogonadism and use of testosterone replacement therapy (TRT) are rising, while data evaluating the complexity and quality of health-care information available to patients on the Internet for hypogonadism or TRT are lacking. This study focuses on characterizing the readability, credibility and quality of patient-centered information for hypogonadism on the Internet. A Google search was performed to identify top-ranked websites offering patient-centered information on hypogonadism and TRT. Readability was quantified by reading grade level using several validated instruments. Credibility and quality were determined by several additional criteria, including authorship, references, health-care information quality certification and breadth of topic discussion. Twenty of 75 total sites identified (27%) met the inclusion and exclusion criteria and were evaluated. The mean reading grade level was 13.1 (interquartile range 11.7-15.1), with all websites demonstrating reading levels significantly above recommended levels. Less than half (45%) of the sites were neither authored nor reviewed by a physician, 60% contained at least one reference and 40% were certified for displaying quality health-care information. Over half (55%) did not comprehensively discuss management of hypogonadism or mention treatment-associated risks. In conclusion, the majority of patient-centered information available on the Internet regarding hypogonadism or TRT is of poor quality and too complex for the average patient to comprehend. These results highlight a critical shortage in easily accessible, high-quality, comprehensible online patient health-care information on hypogonadism and TRT.

Quality and readability of websites for patient information on tonsillectomy and sleep apnea.

PubMed

Chi, Ethan; Jabbour, Noel; Aaronson, Nicole Leigh

2017-07-01

Tonsillectomy is a common treatment for obstructive sleep apnea (OSA). The Internet allows patients direct access to medical information. Since information on the Internet is largely unregulated, quality and readability are variable. This study evaluates the quality and readability of the most likely visited websites presenting information on sleep apnea and tonsillectomy. The three most popular search engines (Google, Bing, Yahoo) were queried with the phrase "sleep apnea AND tonsillectomy." The DISCERN instrument was used to assess quality of information. Readability was evaluated using the Flesch-Kincaid Reading Grade Level (FKGL) and Flesch Reading Ease Score (FRES). Out of the maximum of 80, the average DISCERN quality score for the websites was 55.1 (SD- 12.3, Median- 60.5). The mean score for FRES was 42.3 (SD- 15.9, Median- 45.5), which falls in the range defined as difficult. No website was above the optimal score of 65. The mean score for the FKGL was US grade-level of 10.7 (SD- 1.6, Median- 11.6). Only 4(27%) websites were in the optimal range of 6-8. There was very weak correlation between FRES and DISCERN (r = 0.07) and FKGL and DISCERN (r = 0.21). Tonsillectomy is one of the most common surgeries in the US. However, the internet information readily available to patients varies in quality. Additionally, much of the information is above the recommended grade level for comprehension by the public. By being aware of what information patients are reading online, physicians can better explain treatments and address misunderstandings. Physicians may consider using similar methods to test the readability for their own resources for patient education. Copyright © 2017 Elsevier B.V. All rights reserved.

The US Environmental Protection Agency (EPA) AirNow program provides Air Quality Index (AQI) information to the public, decision-makers, researchers and the media (data and forecasts) mainly for ozone and PM2.5 (particles smaller than 2.5 μm in median diameter). EPA wants to provide the best information available to the public and integrating NASA satellite-derived surface PM2.5 concentrations with ground-level PM2.5 observations has proved promising. The AirNow Satellite Data Processor (ASDP) uses daily PM2.5 estimates and uncertainties derived from average Aqua and Terra MODerate resolution Imaging Spectrometer (MODIS) AOD in near-real-time over the United States and fuses the results with observed PM2.5 measurements to create several air quality products for evaluation. In addition to the description of the AirNow program and the AirNow ASDP, several case studies will be presented to show the value that NASA satellite information adds to maps of air quality.

Websites on the Internet are used increasingly by patients and those caring for them as a source of medical information. This study investigated the nature and quality of the kidney transplant-related information currently available on the World Wide Web (WWW). Four common search engines were used to explore the Internet using the keywords "kidney transplantation." Each website was assessed on the following categories: source, language, accessibility, presence of kitemarks, and quality/depth of information. Websites were scored independently by four transplant clinicians (two surgeons and two physicians), and a weighted Information Score (IS) was created to assess the overall clinical and educational value of the site. A total of 200 potential websites were identified of which 94 websites were suitable for scoring. The remaining 106 were repetitions or non-accessible links. The overall median weighted IS for the sites assessed was 21 (IQR 0-61). Median weighted IS of sites originating from Europe and USA were 47 (IQR = 21-61) and 45 (IQR = 15-61) respectively (p = 0.27). Websites belonging to academic institutions scored higher with a median weighted IS of 49 (IQR = 20-61) when compared with kitemarked websites (median 21, IQR = 5-45, p = 0.01). However, there was no statistically significant difference in weighted IS of kitemarked, professional (median 22, IQR = 2-53), commercial (median 20, IQR = 0-45), and individual websites (median 9, IQR 3-12). There was a good agreement between the observers who scored the websites with an intraclass correlation coefficient (ICC) of 0.79 and an associated 95% CI (0.73-0.90) for the four observers on the 94 websites. The educational material currently available on the WWW about kidney transplantation is often of poor quality and more input is required from transplant clinicians. Quality seals in the form of kitemarks may give a false sense of security. The gaps in validity and accuracy of the information available on complex

A new statistical framework to assess structural alignment quality using information compression

Motivation: Progress in protein biology depends on the reliability of results from a handful of computational techniques, structural alignments being one. Recent reviews have highlighted substantial inconsistencies and differences between alignment results generated by the ever-growing stock of structural alignment programs. The lack of consensus on how the quality of structural alignments must be assessed has been identified as the main cause for the observed differences. Current methods assess structural alignment quality by constructing a scoring function that attempts to balance conflicting criteria, mainly alignment coverage and fidelity of structures under superposition. This traditional approach to measuring alignment quality, the subject of considerable literature, has failed to solve the problem. Further development along the same lines is unlikely to rectify the current deficiencies in the field. Results: This paper proposes a new statistical framework to assess structural alignment quality and significance based on lossless information compression. This is a radical departure from the traditional approach of formulating scoring functions. It links the structural alignment problem to the general class of statistical inductive inference problems, solved using the information-theoretic criterion of minimum message length. Based on this, we developed an efficient and reliable measure of structural alignment quality, I-value. The performance of I-value is demonstrated in comparison with a number of popular scoring functions, on a large collection of competing alignments. Our analysis shows that I-value provides a rigorous and reliable quantification of structural alignment quality, addressing a major gap in the field.

To find out the prevalence of quality trust marks present in websites and to analyse the quality of these websites displaying trust marks compared with those that do not display them, in order to put forward these trust marks as a quality indicator. Cross-sectional study. Internet. Websites on vaccines. Using "vacunas OR vaccines" as key words, the features of 40 web pages were analysed. These web pages were selected from the page results of two search engines, Google and Yahoo! Based on a total of 9 criteria, the average score of criteria fulfilled was 7 (95% CI 3.96-10.04) points for the web pages offered by Yahoo! and 7.3 (95% CI 3.86-10.74) offered by Google. Amongst web pages offered by Yahoo!, there were three with clearly inaccurate information, while there were four in the pages offered by Google. Trust marks were displayed in 20% and 30% medical web pages, respectively, and their presence reached statistical significance (P=0.033) when fulfilling the quality criteria compared with web pages where trust marks were not displayed. A wide variety of web pages was obtained by search engines and a large number of them with useless information. Although the websites analysed had a good quality, between 15% and 20% showed inaccurate information. Websites where trust marks were displayed had more quality than those that did not display one and none of them were included amongst those where inaccurate information was found.

A quality-control YouTube-based study using the recognized quality scoring systems. In this study, our aim was to confirm the accuracy and quality of the information in kyphosis videos shared on YouTube. The Internet is a widely and increasingly used source for obtaining medical information both by patients and clinicians. YouTube, in particular, manifests itself as a leading source with its ease of access to information and visual advantage for Internet users. The first 50 videos returned by the YouTube search engine in response to 'kyphosis' keyword query were included in the study and categorized under seven and six groups, based on their source and content. The popularity of the videos were evaluated with a new index called the video power index (VPI). The quality, educational quality and accuracy of the source of information were measured using the JAMA score, Global Quality Score (GQS) and Kyphosis Specific Score (KSS). Videos had a mean duration of 397 seconds and a mean number of views of 131,644, with a total viewing number of 6,582,221. The source (uploader) in 36% of the videos was a trainer and the content in 46% of the videos was exercise training. 72% of the videos were about postural kyphosis. Videos had a mean JAMA score of 1.36 (range: 1 to 4), GQS of 1.68 (range: 1 to 5) and KSS of 3.02 (range:0 to 32). The academic group had the highest scores and the lowest VPIs. Online information on kyphosis is low quality and its contents are of unknown source and accuracy. In order to keep the balance in sharing the right information with the patient, clinicians should possess knowledge about the online information related to their field, and should contribute to the development of optimal medical videos. 3.

According to the information-seeking behaviors of patients, booklets which can be downloaded from the Internet for free are an important source of information notably for patients with cancer. This study investigated whether information booklets for patients with cancer available at German websites are in accordance with the formal and content criteria of evidence-based information. We compared and compiled both content and formal criteria by matching different national and international standards for written patient information using a merged instrument. A catalog with a total of 16 items within 4 categories (quality of the publication, quality of information, quality of information representation, and transparency) was created. Patient information booklets for the most frequent tumor types were collected from the Internet. A total of 52 different patient booklets were downloaded and assessed. Overall, no booklet fulfilled all criteria. The quality of the publications was evaluated with an average value of 1.67 while the quality of the information had a mean value of 1.45, and the quality of information presentation had a similar rating (1.39). The transparency criteria were evaluated as lowest with an average of 1.07. In summary, German booklets for cancer patients have some shortcomings concerning formal and content criteria for evidence-based patient information. The applied requirement catalog is suitable for wide use and may help in quality assurance of health information. It may be used as part of an obligatory external evaluation, which could help improving the quality of health information.

Service quality and asymmetric information in the regulation of monopolies: The Chilean electricity distribution industry

NASA Astrophysics Data System (ADS)

Melo, Oscar Alfredo

This study is an enquiry about the role that service quality, asymmetric information, scope of regulation and regulator's preferences play in the regulation of monopolies, with an application to the case of the Chilean electricity distribution industry. In Chapter 1, I present the problem of regulating a monopolist and introduce the special conditions that the electricity sector has. Later I discuss the main characteristics of the electricity system that operates in Chile. The literature on regulation is reviewed in Chapter 2. A special emphasis is given to the problems of quality and information, and the lack of its proper joint treatment. In Chapter 3, I develop four theoretical models of regulation that explicitly consider the regulation of price and quality versus price-only regulation, and a symmetric versus asymmetric information structure where only the regulator knows its true costs. In these models, I also consider the effect of a regulator that may have a preference between consumers and the regulated monopolistic firms. I conclude that with symmetric information and independent of the scope of regulation, having a regulator that prefers consumers or producers does not affect the efficiency of the outcome. I also show that the regulator's inability to set quality, thus regulating only price, leads to an inefficient outcome, away from the first best solution that can be achieved by regulating both price and quality, even with asymmetric information, as long as the regulator does not have a "biased" preference for consumers or the monopolistic producers. If the regulator has a "bias," then the equilibrium will be inefficient with asymmetric information. But the effect on equilibrium price and quality depends on the direction of the effect of quality on the marginal effect of price in demand. More importantly, no closed-form solution can be derived unless drastic simplifications are made. To further investigate the outcome of the models, I use numerical

ABSTRACT Although many patients use the internet to access health-related information, the quality and the reliability of the information is highly inconsistent. Periacetabular osteotomy (PAO) is one of the surgical procedures for hip dysplasia. However, medical information on PAO is limited on the internet. This study aims to evaluate the quality and reliability of information available on PAO on the internet in Japan. A web search was conducted on two search engines for the following terms: “hip osteotomy,” “pelvic osteotomy,” and “osteotomy for hip preservation” in Japanese. In total, we found 120 websites. To determine the quality and reliability of information on each website, we used the Health on the Net Foundation (HON) score, the Brief DISCERN score, and an osteotomy-specific content (OSC) score. After eliminating duplicate websites, we reviewed 49 unique websites. Only three websites (6.1%) had good reliability, as indicated by their HON scores. Twelve websites (24.4%) had good-quality information, as measured by their Brief DISCERN scores. As evaluated by their OSC scores, physician websites were found to be biased toward etiology and surgical indication and did not provide information on the complications of procedures. Non-physician websites were generally insufficient. The information about PAO on the internet is, therefore, unreliable and of poor-quality for Japanese patients. PMID:28878442

The Health Information Technology for Economic and Clinical Health Act of 2009 and the Centers for Medicare & Medicaid Services “meaningful use” incentive programs, in tandem with the boundless additional requirements for detailed reporting of quality metrics, have galvanized hospital efforts to implement hospital-based electronic health records. As such, emergency department information systems (EDISs) are an important and unique component of most hospitals’ electronic health records. System functionality varies greatly and affects physician decisionmaking, clinician workflow, communication, and, ultimately, the overall quality of care and patient safety. This article is a joint effort by members of the Quality Improvement and Patient Safety Section and the Informatics Section of the American College of Emergency Physicians. The aim of this effort is to examine the benefits and potential threats to quality and patient safety that could result from the choice of a particular EDIS, its implementation and optimization, and the hospital’s or physician group’s approach to continuous improvement of the EDIS. Specifically, we explored the following areas of potential EDIS safety concerns: communication failure, wrong order–wrong patient errors, poor data display, and alert fatigue. Case studies are presented that illustrate the potential harm that could befall patients from an inferior EDIS product or suboptimal execution of such a product in the clinical environment. The authors have developed 7 recommendations to improve patient safety with respect to the deployment of EDISs. These include ensuring that emergency providers actively participate in selection of the EDIS product, in the design of processes related to EDIS implementation and optimization, and in the monitoring of the system’s ongoing success or failure. Our recommendations apply to emergency departments using any type of EDIS: custom-developed systems, best-of-breed vendor systems, or

In order to promote the construction of digital geo-spatial framework in China and accelerate the construction of informatization mapping system, three-dimensional geographic information model emerged. The three-dimensional geographic information model based on oblique photogrammetry technology has higher accuracy, shorter period and lower cost than traditional methods, and can more directly reflect the elevation, position and appearance of the features. At this stage, the technology of producing three-dimensional geographic information models based on oblique photogrammetry technology is rapidly developing. The market demand and model results have been emerged in a large amount, and the related quality inspection needs are also getting larger and larger. Through the study of relevant literature, it is found that there are a lot of researches on the basic principles and technical characteristics of this technology, and relatively few studies on quality inspection and analysis. On the basis of summarizing the basic principle and technical characteristics of oblique photogrammetry technology, this paper introduces the inspection contents and inspection methods of three-dimensional geographic information model based on oblique photogrammetry technology. Combined with the actual inspection work, this paper summarizes the quality problems of three-dimensional geographic information model based on oblique photogrammetry technology, analyzes the causes of the problems and puts forward the quality control measures. It provides technical guidance for the quality inspection of three-dimensional geographic information model data products based on oblique photogrammetry technology in China and provides technical support for the vigorous development of three-dimensional geographic information model based on oblique photogrammetry technology.

Patients should have access to high-quality health information websites on which to base their decision-making. There are concerns regarding the accuracy and quality of some health websites. We aimed to objectively measure website quality related to cochlear implantation. Selected patient-information websites were scored, depending on how highly they ranked on search engines and if they were ranked on more than one of the search engines used. The top 40 websites from three major search engines were analysed. The quality of each website was scored using the DISCERN tool and the readability was scored using the Flesch-Kincaid reading ease and the Gunning-Fog index. The average Flesch-Kincaid score was 49.7, giving an average reading age of a 15-17 years old, and the average Gunning-fog score was 13.1, which equals that of an 18 years old. Internet-based information regarding cochlear implantation is of varied quality and is written above the expected reading level of an average person.

This study evaluated the readability, accessibility and quality of information pertaining to breast reconstruction post mastectomy on the Internet in the English language. Using the Google © search engine the keywords "Breast reconstruction post mastectomy" were searched for. We analyzed the top 75 sites. The Flesch Reading Ease Score and Gunning Fog Index were calculated to assess readability. Web site quality was assessed objectively using the University of Michigan Consumer Health Web site Evaluation Checklist. Accessibility was determined using an automated accessibility tool. In addition, the country of origin, type of organisation producing the site and presence of Health on the Net (HoN) Certification status was recorded. The Web sites were difficult to read and comprehend. The mean Flesch Reading Ease scores were 55.5. The mean Gunning Fog Index scores was 8.6. The mean Michigan score was 34.8 indicating weak quality of websites. Websites with HoN certification ranked higher in the search results (p = 0.007). Website quality was influenced by organisation type (p < 0.0001) with academic/healthcare, not for profit and government sites having higher Michigan scores. 20% of sites met the minimum accessibility criteria. Internet information on breast reconstruction post mastectomy and procedures is poorly written and we suggest that Webpages providing information must be made more readable and accessible. We suggest that health professionals should recommend Web sites that are easy to read and contain high-quality surgical information. Medical information on the Internet should be readable, accessible, reliable and of a consistent quality. Copyright © 2017 Elsevier Ltd. All rights reserved.

Measuring health care process quality with software quality measures.

Yildiz, Ozkan; Demirörs, Onur

2012-01-01

Existing quality models focus on some specific diseases, clinics or clinical areas. Although they contain structure, process, or output type measures, there is no model which measures quality of health care processes comprehensively. In addition, due to the not measured overall process quality, hospitals cannot compare quality of processes internally and externally. To bring a solution to above problems, a new model is developed from software quality measures. We have adopted the ISO/IEC 9126 software quality standard for health care processes. Then, JCIAS (Joint Commission International Accreditation Standards for Hospitals) measurable elements were added to model scope for unifying functional requirements. Assessment (diagnosing) process measurement results are provided in this paper. After the application, it was concluded that the model determines weak and strong aspects of the processes, gives a more detailed picture for the process quality, and provides quantifiable information to hospitals to compare their processes with multiple organizations.

The Internet is a frequently used source of health information. Adolescents in particular seem to be receptive to online health information (OHI) and often incorporate such information in their decision-making processes. Yet, OHI is often incomplete, inaccurate, or unreliable. This study assessed the quality of Hebrew online (non-user-generated) content on oral contraceptives (OC), with regard to accuracy/completeness, credibility, and usability. Twenty-nine websites in Hebrew, including those of the four Israeli HMOs, were identified and evaluated. The websites were categorized as: HMO, health portal, contraception-specific, promotional-commercial, and life style and women's health. A set of established content parameters was selected by a family planning expert to assess accuracy/completeness. The Health on the Net Foundation Code of Conduct (HONcode) principles were used to assess the websites' reliability. Usability was assessed by applying items selected from the Minervation Validation and the University of Michigan's 'Website Evaluation checklist' scale. Mean scores, standard deviations (SD), and ranges were calculated for all websites and for category-specific websites. Correlation between dimensions and Inter-rater reliability were also examined. The mean score for accuracy/completeness was 50.9% for all websites (SD=30.1%, range 8-100%). Many websites failed to provide complete information, or provided inaccurate information regarding what to do when a pill is missed and when to use back-up methods. The average credibility score for all websites was 70.6% (SD=15.1, range=38=98%). The credibility parameters that were most commonly absent were funding source, authoring, date of content creation and last modification, explicit reference to evidence-based information, and references and citations. The average usability score for all websites was 94.5% (SD=6.9%, range 79-100%). A weak correlation was found between the three quality parameters assessed. Wide

Information transfer in auditoria and room-acoustical quality.

PubMed

Summers, Jason E

2013-04-01

It is hypothesized that room-acoustical quality correlates with the information-transfer rate. Auditoria are considered as multiple-input multiple-output communication channels and a theory of information-transfer is outlined that accounts for time-variant multipath, spatial hearing, and distributed directional sources. Source diversity and spatial hearing are shown to be the mechanisms through which multipath increases the information-transfer rate by overcoming finite spatial resolution. In addition to predictions that are confirmed by recent and historical findings, the theory provides explanations for the influence of factors such as musical repertoire and ensemble size on subjective preference and the influence of multisource, multichannel auralization on perceived realism.

Most US adults have limited health literacy skills. They struggle to understand complex health information and services and to make informed health decisions. The Internet has quickly become one of the most popular places for people to search for information about their health, thereby making access to quality information on the Web a priority. However, there are no standardized criteria for evaluating Web-based health information. Every 10 years, the US Department of Health and Human Services' Office of Disease Prevention and Health Promotion (ODPHP) develops a set of measurable objectives for improving the health of the nation over the coming decade, known as Healthy People. There are two objectives in Healthy People 2020 related to website quality. The first is objective Health Communication and Health Information Technology (HC/HIT) 8.1: increase the proportion of health-related websites that meet 3 or more evaluation criteria for disclosing information that can be used to assess information reliability. The second is objective HC/HIT-8.2: increase the proportion of health-related websites that follow established usability principles. The ODPHP conducted a nationwide assessment of the quality of Web-based health information using the Healthy People 2020 objectives. The ODPHP aimed to establish (1) a standardized approach to defining and measuring the quality of health websites; (2) benchmarks for measurement; (3) baseline data points to capture the current status of website quality; and (4) targets to drive improvement. The ODPHP developed the National Quality Health Website Survey instrument to assess the quality of health-related websites. The ODPHP used this survey to review 100 top-ranked health-related websites in order to set baseline data points for these two objectives. The ODPHP then set targets to drive improvement by 2020. This study reviewed 100 health-related websites. For objective HC/HIT-8.1, a total of 58 out of 100 (58.0%) websites met 3 or

The Internet is now the single largest source of health information and is used by many patients who are affected by epilepsy and their families. To assess the quality of information provided by French website on the different forms of epilepsy and their treatment, we used search engines (French pages from Bing, Google and Yahoo) to look for information using the French equivalent of three keywords epilepsy (Épilepsie); epilepsy treatment (Épilepsie traitement) and seizure (Convulsions). The websites were evaluated for content quality by using an adaptation of the validated DISCERN rating instrument. Each website was evaluated by three investigators (a naive observer, a pediatric neurologist and a neurologist). Most of the information on epilepsy and its treatment were from community websites. We found six French websites which were scored higher than half of the maximal value of our scoring system (≥27.5/55): www.passeportsante.net; fr.wikipedia.org; www.fondation-epilepsie.fr; www.epilepsie-france.fr; www.doctissimo.fr; www.caducee.net. This study provides a list of French websites that have been evaluated for the quality of their information. We did not observe any correlation between the quality of the information and priority on search engine listings. Websites sponsored by patients associations and by institutions should update their content more frequently or work on their search engine indexation to appear higher on search engine listings.

Written information is commonly used to inform patients about their disease and treatment but must be evidence-based and understandable to be useful. This study assessed the quality of the content and the readability of information brochures for people affected by brain tumours. We randomly selected 18 publicly available brochures. Brochures were assessed by criteria to assess the quality of content using the DISCERN instrument. Readability was tested using three commonly used formulas, which yield the reading grade level required to comprehend the brochure (sixth grade level recommended). The mean overall DISCERN score was 3.17 out of a maximum of 5 (moderate quality); only one achieved a rating greater than 4 (high quality). Only one brochure met the sixth grade readability criteria. Although brochures may have accurate content, few satisfied all of the recommended criteria to evaluate their content. Existing brochures need to be critically reviewed and simplified and consumer-focused brochures, produced.

Assessing Volunteered Geographic Information (vgi) Quality Based on CONTRIBUTORS' Mapping Behaviours

NASA Astrophysics Data System (ADS)

Bégin, D.; Devillers, R.; Roche, S.

2013-05-01

VGI changed the mapping landscape by allowing people that are not professional cartographers to contribute to large mapping projects, resulting at the same time in concerns about the quality of the data produced. While a number of early VGI studies used conventional methods to assess data quality, such approaches are not always well adapted to VGI. Since VGI is a user-generated content, we posit that features and places mapped by contributors largely reflect contributors' personal interests. This paper proposes studying contributors' mapping processes to understand the characteristics and quality of the data produced. We argue that contributors' behaviour when mapping reflects contributors' motivation and individual preferences in selecting mapped features and delineating mapped areas. Such knowledge of contributors' behaviour could allow for the derivation of information about the quality of VGI datasets. This approach was tested using a sample area from OpenStreetMap, leading to a better understanding of data completeness for contributor's preferred features.

The exponential increase in health-related online platforms has made the Internet one of the main sources of health information globally. The quality of health contents disseminated on the Internet has been a central focus for many researchers. To date, however, few comparative content analyses of pro- and anti-vaccination websites have been conducted, and none of them compared the quality of information. The main objective of this study was therefore to bring new evidence on this aspect by comparing the quality of pro- and anti-vaccination online sources. Based on past literature and health information quality evaluation initiatives, a 40-categories assessment tool (Online Vaccination Information Quality Codebook) was developed and used to code a sample of 1093 webpages retrieved via Google and two filtered versions of the same search engine. The categories investigated were grouped into four main quality dimensions: web-related design quality criteria (10 categories), health-specific design quality criteria (3 categories), health related content attributes (12 categories) and vaccination-specific content attributes (15 categories). Data analysis comprised frequency counts, cross tabulations, Pearson's chi-square, and other inferential indicators. The final sample included 514 webpages in favor of vaccination, 471 against, and 108 neutral. Generally, webpages holding a favorable view toward vaccination presented more quality indicators compared to both neutral and anti-vaccination pages. However, some notable exceptions to this rule were observed. In particular, no differences were found between pro- and anti-vaccination webpages as regards vaccination-specific content attributes. Our analyses showed that the overall quality of pro-vaccination webpages is superior to anti-vaccination online sources. The developed coding scheme was proven to be a helpful and reliable tool to judge the quality of vaccination-related webpages. Based on the results, we advance

A recent report from the Institute of Medicine titled Delivering High-Quality Cancer Care: Charting a New Course for a System in Crisis, identifies improvement in information technology (IT) as essential to improving the quality of cancer care in America. The report calls for implementation of a learning healthcare IT system: a system that supports patient-clinician interactions by providing patients and clinicians with the information and tools necessary to make well informed medical decisions and to support quality measurement and improvement. While some elements needed for a learning healthcare system are already in place for cancer, they are incompletely implemented, have functional deficiencies, and are not integrated in a way that creates a true learning healthcare system. To achieve the goal of a learning cancer care delivery system, clinicians, professional organizations, government, and the IT industry will have to partner, develop, and incentivize participation.

2011-01-01

Background Patients living with fibromyalgia strongly prefer to access health information on the web. However, the majority of subjects in previous studies strongly expressed their concerns about the quality of online information resources. Objectives The purpose of this study was to evaluate existing online fibromyalgia information resources for content, quality and readability by using standardised quality and readability tools. Methods The first 25 websites were identified using Google and the search keyword ‘fibromyalgia’. Pairs of raters independently evaluated website quality using two structured tools (DISCERN and a quality checklist). Readability was assessed using the Flesch Reading Ease score maps. Results Ranking of the websites' quality varied by the tool used, although there was general agreement about the top three websites (Fibromyalgia Information, Fibromyalgia Information Foundation and National Institute of Arthritis and Musculoskeletal and Skin Diseases). Content analysis indicated that 72% of websites provided information on treatment options, 68% on symptoms, 60% on diagnosis and 40% on coping and resources. DISCERN ratings classified 32% websites as ‘very good’, 32% as ‘good and 36% as ‘marginal’. The mean overall DISCERN score was 36.88 (good). Only 16% of websites met the recommended literacy level grade of 6–8 (range 7–15). Conclusion Higher quality websites tended to be less readable. Online fibromyalgia information resources do not provide comprehensive information about fibromyalgia, and have low quality and poor readability. While information is very important for those living with fibromyalgia, current resources are unlikely to provide necessary or accurate information, and may not be usable for most people.

Background Patients living with fibromyalgia strongly prefer to access health information on the web. However, the majority of subjects in previous studies strongly expressed their concerns about the quality of online information resources. Objectives The purpose of this study was to evaluate existing online fibromyalgia information resources for content, quality and readability by using standardised quality and readability tools. Methods The first 25 websites were identified using Google and the search keyword 'fibromyalgia'. Pairs of raters independently evaluated website quality using two structured tools (DISCERN and a quality checklist). Readability was assessed using the Flesch Reading Ease score maps. Results Ranking of the websites' quality varied by the tool used, although there was general agreement about the top three websites (Fibromyalgia Information, Fibromyalgia Information Foundation and National Institute of Arthritis and Musculoskeletal and Skin Diseases). Content analysis indicated that 72% of websites provided information on treatment options, 68% on symptoms, 60% on diagnosis and 40% on coping and resources.

Background Most existing tools for measuring the quality of Internet health information focus almost exclusively on structural criteria or other proxies for quality information rather than evaluating actual accuracy and comprehensiveness. Objective This research sought to develop a new performance-measurement tool for evaluating the quality of Internet health information, test the validity and reliability of the tool, and assess the variability in diabetes Web site quality. Methods An objective, systematic tool was developed to evaluate Internet diabetes information based on a quality-of-care measurement framework. The principal investigator developed an abstraction tool and trained an external reviewer on its use. The tool included 7 structural measures and 34 performance measures created by using evidence-based practice guidelines and experts' judgments of accuracy and comprehensiveness. Results Substantial variation existed in all categories, with overall scores following a normal distribution and ranging from 15% to 95% (mean was 50% and median was 51%). Lin's concordance correlation coefficient to assess agreement between raters produced a rho of 0.761 (Pearson's r of 0.769), suggesting moderate to high agreement. The average agreement between raters for the performance measures was 0.80. Conclusions Diabetes Web site quality varies widely. Alpha testing of this new tool suggests that it could become a reliable and valid method for evaluating the quality of Internet health sites. Such an instrument could help lay people distinguish between beneficial and misleading information. PMID:14713658

Adolescence is a vulnerable time for teens with sickle cell disease (SCD). Although there is evidence to support the use of web-based education to promote self-management skills in patients with chronic illnesses, the quality of SCD-related information on the Internet has not been assessed. A website review was conducted to appraise the quality, content, accuracy, readability, and desirability of online information for the adolescents with SCD. Relevant keywords were searched on the most popular search engines. Websites meeting predetermined criteria were reviewed. The quality of information was appraised using the validated DISCERN tool. Two physicians independently rated website completeness and accuracy. Readability of the sites was documented using the simple measure of gobbledygook (SMOG) scores and the Flesch Reading Ease (FRE). The website features considered desirable by youth were tracked. Search results yielded >600 websites with 25 unique hits meeting criteria. The overall quality of the information was "fair" and the average DISCERN rating score was 50.1 (±9.3, range 31.0-67.5). Only 12 of 25 (48%) websites had scores >50. The average completeness score was 20 of 29 (±5, range 12-27). No errors were identified. The mean SMOG score was 13.04 (±2.80, range 10.21-22.85) and the mean FRE score was 46.05 (±11.47; range 17.50-66.10), suggesting that the material was written well beyond the acceptable reading level for patient education. The websites were text-heavy and lacked the features that appeal to youth (chat, games, videos, etc.). Given the paucity of high-quality health information available for the teens with SCD, it is essential that additional online resources be developed. © 2016 Wiley Periodicals, Inc.

2008-12-01

Tanzania (TZ) has one of the highest rates of child mortality due to enteric disease in the world. NGOs and local agencies have introduced numerous technologies (e.g., chlorine tablets, borewells) to increase the quantity and quality of water in Dar es Salaam, the capital of Tanzania, in hopes of reducing morbidity and mortality of waterborne disease. The objective of the present study is to determine if providing personalized information about water quality and hand surface quality, as determined by concentrations of enterococci and E. coli, results in improved health and water quality in households. A cohort study was completed in June-September 2008 in 3 communities ranging from urban to per-urban in Dar es Salaam, Tanzania to achieve our objective. The study consisted of 4 cohorts that were visited 4 times over the 3 month study. One cohort received no information about water and hand quality until the end of the summer, while the other groups received either just information on hand surface quality, just information on water quality, and information on both hand surface and water quality after the first (baseline) household visit. We report concentrations of enterococci and E. coli in water sources (surface waters and bore wells), water stored in households, and environmental waters were children and adults swim and bathe. In addition, we report concentrations of enterococci and E. coli on hands of caregivers and children in households. Preliminary results of surveys on health and perceptions of water quality and illness from the households are provided. Ongoing work will integrate the microbiological and sociological data sets to determine if personalized information interventions resulted in changes in health, water quality in the household, or perceptions of water quality, quantity and relation to human health. Future work will analyze DNA samples from hands and water for human-specific Bacteroides bacteria which are only present in human feces. Our study

Recent emphasis on shared decision making and patient-centered research has increased the importance of patient education and health literacy. The internet is rapidly growing as a source of self-education for patients. However, concern exists over the quality, accuracy, and readability of the information. Our objective was to determine whether the quality, accuracy, and readability of information online about distal radius fractures vary with the search term. This was a prospective evaluation of 3 search engines using 3 different search terms of varying sophistication ("distal radius fracture," "wrist fracture," and "broken wrist"). We evaluated 70 unique Web sites for quality, accuracy, and readability. We used comparative statistics to determine whether the search term affected the quality, accuracy, and readability of the Web sites found. Three orthopedic surgeons independently gauged quality and accuracy of information using a set of predetermined scoring criteria. We evaluated the readability of the Web site using the Fleisch-Kincaid score for reading grade level. There were significant differences in the quality, accuracy, and readability of information found, depending on the search term. We found higher quality and accuracy resulted from the search term "distal radius fracture," particularly compared with Web sites resulting from the term "broken wrist." The reading level was higher than recommended in 65 of the 70 Web sites and was significantly higher when searching with "distal radius fracture" than "wrist fracture" or "broken wrist." There was no correlation between Web site reading level and quality or accuracy. The readability of information about distal radius fractures in most Web sites was higher than the recommended reading level for the general public. The quality and accuracy of the information found significantly varied with the sophistication of the search term used. Physicians, professional societies, and search engines should consider

Evaluating the quality and readability of thyroplasty information on the Internet.

2014-05-01

To assess the quality and readability of thyroplasty information available on the Internet. Cross-sectional study. We conducted a Google search for "thyroplasty treatment" and analyzed the first 50 Web sites using the DISCERN instrument, the Flesch Reading Ease Score (FRES), and the Flesch-Kincaid Grade Level (FKGL) score. DISCERN is a 16-item validated questionnaire used to assess the quality of written health information for patients. FRES and FKGL are commonly used instruments to assess readability of written information. We also further analyzed major versus minor and patient-targeted versus professional Web sites. Overall DISCERN score was 2.20 ± 0.60. Overall FRES score was 29.68 ± 16.64. Overall FKGL score was 13.07 ± 3.95. We found significant differences between patient-targeted and professional Web sites on FRES (43.80 ± 2.78 and 18.58 ± 9.04, respectively) and FKGL (11.46 ± 3.36 and 14.33 ± 4.30, respectively) (P < 0.00 and P = 0.01, respectively). We also found significant differences between major and minor Web sites on DISCERN (2.35 ± 2.35 and 1.95 ± 0.61, respectively), FRES (24.75 ± 14.61 and 37.71 ± 16.97, respectively), and FKGL (14.19 ± 3.68 and 11.24 ± 3.77, respectively) (P = 0.03, 0.01, and 0.01, respectively). Thyroplasty information available online is of suboptimal quality and written at a level too difficult for the average American adult to read comfortably. Major Web sites have higher quality information but are more difficult to read. Professional Web sites are also more difficult to read than patient-targeted Web sites.

[Prediction of regional soil quality based on mutual information theory integrated with decision tree algorithm].

PubMed

Lin, Fen-Fang; Wang, Ke; Yang, Ning; Yan, Shi-Guang; Zheng, Xin-Yu

2012-02-01

In this paper, some main factors such as soil type, land use pattern, lithology type, topography, road, and industry type that affect soil quality were used to precisely obtain the spatial distribution characteristics of regional soil quality, mutual information theory was adopted to select the main environmental factors, and decision tree algorithm See 5.0 was applied to predict the grade of regional soil quality. The main factors affecting regional soil quality were soil type, land use, lithology type, distance to town, distance to water area, altitude, distance to road, and distance to industrial land. The prediction accuracy of the decision tree model with the variables selected by mutual information was obviously higher than that of the model with all variables, and, for the former model, whether of decision tree or of decision rule, its prediction accuracy was all higher than 80%. Based on the continuous and categorical data, the method of mutual information theory integrated with decision tree could not only reduce the number of input parameters for decision tree algorithm, but also predict and assess regional soil quality effectively.

Toward Obtaining Reliable Particulate Air Quality Information from Satellites

Air quality agencies use ground sites to monitor air quality, providing accurate information at particular points. Using measurements from satellite imagery has the potential to provide air quality information in a timely manner with better spatial resolution and at a lower cost that can also useful for model validation. While previous studies show acceptable correlations between Aerosol Optical Depth (AOD) derived from MODIS and surface Particulate Matter (PM) measurements on the eastern US, the data do not correlate well in the western US (Al-Saadi et al., 2005; Engle-Cox et al., 2004) . This paper seeks to improve the AOD-PM correlations by using advanced statistical analysis techniques. Our study area is the San Joaquin Valley in California because air quality in this region has failed to meet state and federal attainment standards for PM for the past several years. A previous investigation found good correlation of the AOD values between MODIS, MISR and AERONET, but poor correlations (R2 ~ 0.02) between satellite-based AOD and surface PM2.5 measurements. PM2.5 measurements correlated somewhat better (R2 ~ 0.18) with MODIS-derived AOD using the Deep Blue surface reflectance algorithm (Hsu et al., 2006) rather than the standard MODIS algorithm. This level of correlation is not adequate for reliable air quality measurements. Pelletier et al. (2007) used generalized additive models (GAMs) and meteorological data to improve the correlation between PM and AERONET AOD in western Europe. Additive models are more flexible than linear models and the functional relationships can be plotted to give a sense of the relationship between the predictor and the response. In this paper we use GAMs to improve surface PM2.5 to MODIS-AOD correlations. For example, we achieve an R2 ~ 0.44 using a GAM that includes the Deep Blue AOD, and day of year as parameters. Including NOx observations, improves the R2 ~ 0.64. Surprisingly Ångström exponent did not prove to be a significant

Making Quality Health Websites a National Public Health Priority: Toward Quality Standards

PubMed Central

2016-01-01

Background Most US adults have limited health literacy skills. They struggle to understand complex health information and services and to make informed health decisions. The Internet has quickly become one of the most popular places for people to search for information about their health, thereby making access to quality information on the Web a priority. However, there are no standardized criteria for evaluating Web-based health information. Every 10 years, the US Department of Health and Human Services' Office of Disease Prevention and Health Promotion (ODPHP) develops a set of measurable objectives for improving the health of the nation over the coming decade, known as Healthy People. There are two objectives in Healthy People 2020 related to website quality. The first is objective Health Communication and Health Information Technology (HC/HIT) 8.1: increase the proportion of health-related websites that meet 3 or more evaluation criteria for disclosing information that can be used to assess information reliability. The second is objective HC/HIT-8.2: increase the proportion of health-related websites that follow established usability principles. Objective The ODPHP conducted a nationwide assessment of the quality of Web-based health information using the Healthy People 2020 objectives. The ODPHP aimed to establish (1) a standardized approach to defining and measuring the quality of health websites; (2) benchmarks for measurement; (3) baseline data points to capture the current status of website quality; and (4) targets to drive improvement. Methods The ODPHP developed the National Quality Health Website Survey instrument to assess the quality of health-related websites. The ODPHP used this survey to review 100 top-ranked health-related websites in order to set baseline data points for these two objectives. The ODPHP then set targets to drive improvement by 2020. Results This study reviewed 100 health-related websites. For objective HC/HIT-8.1, a total of 58 out

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

Providing informal home care for pressure ulcer patients: how it affects carers' quality of life and burden.

To evaluate the quality of life of informal caregivers of patients with pressure ulcer; to assess their levels of burden; to analyse the variables influencing both their quality of life and burden. Informal caregivers of pressure ulcer patients, besides coping with the natural dependency of these patients, deal with the specificity of caring these types of wounds. This situation has an impact on not only the quality of life and burden felt by informal caregivers but also on individual and familiar dynamics. Descriptive and correlational study. This study focused on 145 informal caregivers providing home care. Measurement instruments were: SF-36v2 and the Burden Interview Scale. Descriptive analysis of the quantitative variables was carried out according to measures of central tendency, and the qualitative variables were described using absolute and relative frequencies. The relationships or associations between variables were explored through correlational analysis and, whenever the data allowed, multivariate techniques were used. Informal caregivers showed low levels of quality of life and, most of them, significant burden. Quality of life decreased with overload, with the increasing number of pressure ulcer and with less experience of informal caregivers, with lack of financial remuneration, with unemployment, with patient positioning and with the direct care of the wound. The burden increased with the number of pressure ulcer in each patient and with the lack of financial remuneration. These informal caregivers have low quality of life and are overburdened. Both situations are positively and negatively influenced by factors related to the pressure ulcer and to the patients' sociodemographic data. The results of this study allow more effective monitoring by health professionals of levels of burden and quality of life encountered in pressure ulcer informal caregivers, as well as direct interventions to inhibit the factors inducing burden and enhance those that

Quality of online health information about oral contraceptives from Hebrew-language websites

PubMed Central

2012-01-01

Background The Internet is a frequently used source of health information. Adolescents in particular seem to be receptive to online health information (OHI) and often incorporate such information in their decision-making processes. Yet, OHI is often incomplete, inaccurate, or unreliable. This study assessed the quality of Hebrew online (non-user-generated) content on oral contraceptives (OC), with regard to accuracy/completeness, credibility, and usability. Methods Twenty-nine websites in Hebrew, including those of the four Israeli HMOs, were identified and evaluated. The websites were categorized as: HMO, health portal, contraception-specific, promotional-commercial, and life style and women’s health. A set of established content parameters was selected by a family planning expert to assess accuracy/completeness. The Health on the Net Foundation Code of Conduct (HONcode) principles were used to assess the websites’ reliability. Usability was assessed by applying items selected from the Minervation Validation and the University of Michigan’s ′Website Evaluation checklist′ scale. Mean scores, standard deviations (SD), and ranges were calculated for all websites and for category-specific websites. Correlation between dimensions and Inter-rater reliability were also examined. Results The mean score for accuracy/completeness was 50.9% for all websites (SD=30.1%, range 8–100%). Many websites failed to provide complete information, or provided inaccurate information regarding what to do when a pill is missed and when to use back–up methods. The average credibility score for all websites was 70.6% (SD=15.1, range=38=98%). The credibility parameters that were most commonly absent were funding source, authoring, date of content creation and last modification, explicit reference to evidence-based information, and references and citations. The average usability score for all websites was 94.5% (SD=6.9%, range 79–100%). A weak correlation was found between the

The ethical duty to preserve the quality of scientific information

The commitment to communicate and divulge the knowledge acquired during his/her professional activity is certainly one of the ethical duties of the geologist. However nowadays, in the Internet era, the spreading of knowledge involves potential risks that the geologist should be aware of. These risks require a careful analysis aimed to mitigate their effects. The Internet may in fact contribute to spread (e.g. through websites like Wikipedia) information badly or even incorrectly presented. The final result could be an impediment to the diffusion of knowledge and a reduction of its effectiveness, which is precisely the opposite of the goal that a geologist should pursue. Specific criteria aimed to recognize incorrect or inadequate information would be, therefore, extremely useful. Their development and application might avoid, or at least reduce, the above mentioned risk. Ideally, such criteria could be also used to develop specific algorithms to automatically verify the quality of information available all over the Internet. A possible criterion will be here presented for the quality control of knowledge and scientific information. An example of its application in the field of geology will be provided, to verify and correct a piece of information available on the Internet. The proposed criterion could be also used for the simplification of the scientific information and the increase of its informative efficacy.

2016-03-01

The research achievements and trends of spectral technology in fast detection of Camellia sinensis growth process information and tea quality information were being reviewed. Spectral technology is a kind of fast, nondestructive, efficient detection technology, which mainly contains infrared spectroscopy, fluorescence spectroscopy, Raman spectroscopy and mass spectroscopy. The rapid detection of Camellia sinensis growth process information and tea quality is helpful to realize the informatization and automation of tea production and ensure the tea quality and safety. This paper provides a review on its applications containing the detection of tea (Camellia sinensis) growing status(nitrogen, chlorophyll, diseases and insect pest), the discrimination of tea varieties, the grade discrimination of tea, the detection of tea internal quality (catechins, total polyphenols, caffeine, amino acid, pesticide residual and so on), the quality evaluation of tea beverage and tea by-product, the machinery of tea quality determination and discrimination. This paper briefly introduces the trends of the technology of the determination of tea growth process information, sensor and industrial application. In conclusion, spectral technology showed high potential to detect Camellia sinensis growth process information, to predict tea internal quality and to classify tea varieties and grades. Suitable chemometrics and preprocessing methods is helpful to improve the performance of the model and get rid of redundancy, which provides the possibility to develop the portable machinery. Future work is to develop the portable machinery and on-line detection system is recommended to improve the further application. The application and research achievement of spectral technology concerning about tea were outlined in this paper for the first time, which contained Camellia sinensis growth, tea production, the quality and safety of tea and by-produce and so on, as well as some problems to be solved

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.

The complexity of modern practice requires health professionals to be active information-seekers. Our aim was to review the quality and progress of point-of-care information summaries-Web-based medical compendia that are specifically designed to deliver pre-digested, rapidly accessible, comprehensive, and periodically updated information to health care providers. We aimed to evaluate product claims of being evidence-based. We updated our previous evaluations by searching Medline, Google, librarian association websites, and conference proceedings from August 2012 to December 2014. We included Web-based, regularly updated point-of-care information summaries with claims of being evidence-based. We extracted data on the general characteristics and content presentation of products, and we quantitatively assessed their breadth of disease coverage, editorial quality, and evidence-based methodology. We assessed potential relationships between these dimensions and compared them with our 2008 assessment. We screened 58 products; 26 met our inclusion criteria. Nearly a quarter (6/26, 23%) were newly identified in 2014. We accessed and analyzed 23 products for content presentation and quantitative dimensions. Most summaries were developed by major publishers in the United States and the United Kingdom; no products derived from low- and middle-income countries. The main target audience remained physicians, although nurses and physiotherapists were increasingly represented. Best Practice, Dynamed, and UptoDate scored the highest across all dimensions. The majority of products did not excel across all dimensions: we found only a moderate positive correlation between editorial quality and evidence-based methodology (r=.41, P=.0496). However, all dimensions improved from 2008: editorial quality (P=.01), evidence-based methodology (P=.015), and volume of diseases and medical conditions (P<.001). Medical and scientific publishers are investing substantial resources towards the

Background The complexity of modern practice requires health professionals to be active information-seekers. Objective Our aim was to review the quality and progress of point-of-care information summaries—Web-based medical compendia that are specifically designed to deliver pre-digested, rapidly accessible, comprehensive, and periodically updated information to health care providers. We aimed to evaluate product claims of being evidence-based. Methods We updated our previous evaluations by searching Medline, Google, librarian association websites, and conference proceedings from August 2012 to December 2014. We included Web-based, regularly updated point-of-care information summaries with claims of being evidence-based. We extracted data on the general characteristics and content presentation of products, and we quantitatively assessed their breadth of disease coverage, editorial quality, and evidence-based methodology. We assessed potential relationships between these dimensions and compared them with our 2008 assessment. Results We screened 58 products; 26 met our inclusion criteria. Nearly a quarter (6/26, 23%) were newly identified in 2014. We accessed and analyzed 23 products for content presentation and quantitative dimensions. Most summaries were developed by major publishers in the United States and the United Kingdom; no products derived from low- and middle-income countries. The main target audience remained physicians, although nurses and physiotherapists were increasingly represented. Best Practice, Dynamed, and UptoDate scored the highest across all dimensions. The majority of products did not excel across all dimensions: we found only a moderate positive correlation between editorial quality and evidence-based methodology (r=.41, P=.0496). However, all dimensions improved from 2008: editorial quality (P=.01), evidence-based methodology (P=.015), and volume of diseases and medical conditions (P<.001). Conclusions Medical and scientific publishers are

Image gathering and coding are commonly treated as tasks separate from each other and from the digital processing used to restore and enhance the images. The goal is to develop a method that allows us to assess quantitatively the combined performance of image gathering and coding for the digital restoration of images with high visual quality. Digital restoration is often interactive because visual quality depends on perceptual rather than mathematical considerations, and these considerations vary with the target, the application, and the observer. The approach is based on the theoretical treatment of image gathering as a communication channel (J. Opt. Soc. Am. A2, 1644(1985);5,285(1988). Initial results suggest that the practical upper limit of the information contained in the acquired image data range typically from approximately 2 to 4 binary information units (bifs) per sample, depending on the design of the image-gathering system. The associated information efficiency of the transmitted data (i.e., the ratio of information over data) ranges typically from approximately 0.3 to 0.5 bif per bit without coding to approximately 0.5 to 0.9 bif per bit with lossless predictive compression and Huffman coding. The visual quality that can be attained with interactive image restoration improves perceptibly as the available information increases to approximately 3 bifs per sample. However, the perceptual improvements that can be attained with further increases in information are very subtle and depend on the target and the desired enhancement.

Media plays a vital role in shaping public policies and opinions through disseminating health-related information. This study aims at exploring the role of media in informing health policies in Lebanon, identifying the factors influencing health reporting and investigating the role of evidence in health journalism and the quality of health reporting. It also identifies strategies to enhance the use of evidence in health journalism and improve the quality of health reporting. Media analysis was conducted to assess the way media reports on health-related issues and the quality of reporting using a quality assessment tool. Semi-structured interviews were also conducted with 27 journalists, researchers and policymakers to explore their perception on the role of media in health policymaking and the factors influencing health reporting. In addition, a validation workshop was conducted. Out of 1,279 health-related news articles identified, 318 articles used certain type of evidence to report health issues 39.8% of which relied on experts' opinions as their source of evidence while only 5.9% referenced peer-reviewed research studies. The quality of health reporting was judged to be low based on a quality assessment tool consisting of a set of ten criteria. Journalists raised concerns about issues impeding them from referring to evidence. Journalists also reported difficulties with the investigative health journalism. Policymakers and researchers viewed media as an important tool for evidence-informed health policies, however, serious concerns were voiced in terms of the current practice and capacities. Our study provides a structured reflection on the role of media and the factors that influence health reporting including context-specific strategies that would enhance the quality and promote the use of evidence in health reporting. In the light of the political changes in many Middle Eastern countries, findings from this study can contribute to redefining the role of media

This study examines the quality of websites providing information on ulcerative colitis, including treatment options and surgery. Two search engines (Google and Yahoo) and the search term 'surgery for ulcerative colitis' were used. The first 50 sites obtained with each search engine were assessed. Sites were evaluated for content and scored using the DISCERN instrument, which evaluates the quality of health information on treatment choices. One hundred sites were examined, of which 14 were duplicates. Of the remainder, 58 provided patient-orientated information for adults and one site provided information for surgery in children. The other 27 sites included six scientific articles, three blogs, three links, six resources for clinicians, five fora, two video links and two dead links. Of the 58 websites that provided patient information for adults, only 26 (44.8%) had been updated within the last 2 years. Only 13/58 (22.4%) were affiliated to hospitals and clinics. Most sites (38/58, 65.5%) were associated with private companies with commercial interests. Although most websites contained information on symptoms and treatment options for ulcerative colitis, 37 (63.8%) did not describe any of the risks of surgery. Overall, only seven (12.1%) websites were identified as being 'good' or 'excellent' using the DISCERN criteria. The quality of patient information on surgery for ulcerative colitis is highly variable. There is potential for internet provision of valuable information and clinicians should guide patients with to access high-quality websites.

Dubowicz, Arthur; Schulz, Peter J

2015-03-30

Most of adult Internet users have searched for health information on the Internet. The Internet has become one of the most important sources for health information and treatment advice. In most cases, the information found is not verified with a medical doctor, but judged by the "online-diagnosers" independently. Facing this situation, public health authorities raise concern over the quality of medical information laypersons can find on the Internet. The objective of the study was aimed at developing a measure to evaluate the credibility of websites that offer medical advice and information. The measure was tested in a quasi-experimental study on two sleeping-disorder websites of different quality. There were 45 survey items for rating the credibility of websites that were tested in a quasi-experimental study with a random assignment of 454 participants to either a high- or a low-quality website exposure. Using principal component analysis, the original items were reduced to 13 and sorted into the factors: trustworthiness, textual deficits of the content, interferences (external links on the Web site), and advertisements. The first two factors focus more on the provided content itself, while the other two describe the embedding of the content into the website. The 45 survey items had been designed previously using exploratory observations and literature research. The final scale showed adequate power and reliability for all factors. The loadings of the principal component analysis ranged satisfactorily (.644 to .854). Significant differences at P<.001 were found between the low- and high-quality groups. Advertisements on the website were rated as disturbing in both experimental conditions, meaning that they do not differentiate between good and bad information. The scale reliably distinguished high- and low-quality of medical advice given on websites.

This study aimed to assess the quality of information available on the World Wide Web for patients undergoing thyroidectomy. The first 50 web-links generated by internet searches using the five most popular search engines and the key word 'thyroidectomy' were evaluated using the Lida website validation instrument (assessing accessibility, usability and reliability) and the Flesch Reading Ease Score. We evaluated 103 of a possible 250 websites. Mean scores (ranges) were: Lida accessibility, 48/63 (27-59); Lida usability, 36/54 (21-50); Lida reliability, 21/51 (4-38); and Flesch Reading Ease, 43.9 (2.6-77.6). The quality of internet health information regarding thyroidectomy is variable. High ranking and popularity are not good indicators of website quality. Overall, none of the websites assessed achieved high Lida scores. In order to prevent the dissemination of inaccurate or commercially motivated information, we recommend independent labelling of medical information available on the World Wide Web.

Background Directing patients suffering from third molars (TMs) problems to high-quality online information is not only medically important, but also could enable better engagement in shared decision making. Objectives This study aimed to develop a scale that measures the scientific information quality (SIQ) for online information concerning wisdom tooth problems and to conduct a quality evaluation for online TMs resources. In addition, the study evaluated whether a specific piece of readability software (Readability Studio Professional 2012) might be reliable in measuring information comprehension, and explored predictors for the SIQ Scale. Methods A cross-sectional sample of websites was retrieved using certain keywords and phrases such as “impacted wisdom tooth problems” using 3 popular search engines. The retrieved websites (n=150) were filtered. The retained 50 websites were evaluated to assess their characteristics, usability, accessibility, trust, readability, SIQ, and their credibility using DISCERN and Health on the Net Code (HoNCode). Results Websites’ mean scale scores varied significantly across website affiliation groups such as governmental, commercial, and treatment provider bodies. The SIQ Scale had a good internal consistency (alpha=.85) and was significantly correlated with DISCERN (r=.82, P<.01) and HoNCode (r=.38, P<.01). Less than 25% of websites had SIQ scores above 75%. The mean readability grade (10.3, SD 1.9) was above the recommended level, and was significantly correlated with the Scientific Information Comprehension Scale (r=.45. P<.01), which provides evidence for convergent validity. Website affiliation and DISCERN were significantly associated with SIQ (P<.01) and explained 76% of the SIQ variance. Conclusion The developed SIQ Scale was found to demonstrate reliability and initial validity. Website affiliation, DISCERN, and HoNCode were significant predictors for the quality of scientific information. The Readability Studio

National Wildlife Refuges may have impaired water quality resulting from historic and current land uses, upstream sources, and aerial pollutant deposition. National Wildlife Refuge staff have limited time available to identify and evaluate potential water quality issues. As a result, water quality–related issues may not be resolved until a problem has already arisen. The National Wildlife Refuge System Water Quality Information System (WQIS) is a relational database developed for use by U.S. Fish and Wildlife Service staff to identify existing water quality issues on refuges in the United States. The WQIS database relies on a geospatial overlay analysis of data layers for ownership, streams and water quality. The WQIS provides summary statistics of 303(d) impaired waters and total maximum daily loads for the National Wildlife Refuge System at the national, regional, and refuge level. The WQIS allows U.S. Fish and Wildlife Service staff to be proactive in addressing water quality issues by identifying and understanding the current extent and nature of 303(d) impaired waters and subsequent total maximum daily loads. Water quality data are updated bi-annually, making it necessary to refresh the WQIS to maintain up-to-date information. This manual outlines the steps necessary to update the data and reports in the WQIS.

Group Health Cooperative of Puget Sound (GHC), a large staff-model health maintenance organization based in Seattle, is redesigning its information systems to provide the systems and information needed to support its quality agenda. Long-range planning for GHC's information resources was done in three phases. In assessment, interviews, surveys, and a benchmarking effort identified strengths and weaknesses of the existing information systems. We concluded that we needed to improve clinical care and patient management systems and enhance health plan applications. In direction setting, we developed six objectives (for example, approach information systems in a way that is consistent with quality improvement principles). Detailed planning was used to define projects, timing, and resource allocations. Some of the most important efforts in the resulting five-year plan include the development of (1) a computerized patient record; (2) a provider-based clinical workstation for access to patient information, order entry, results reporting, guidelines, and reminders; (3) a comprehensive set of patient management and service quality systems; (4) reengineered structures, policies, and processes within the health plan, supported by a complete set of integrated information systems; (5) a standardized, high-capacity communications network to provide linkages both within GHC and among its business partners; and (6) a revised oversight structure for information services, which forms partnerships with users. A quality focus ensured that each project not only produced its own benefits but also supported the larger organizational goals associated with "total" quality.

To determine the quality and content of English language Internet information about juvenile idiopathic arthritis (JIA) from the perspectives of consumers and healthcare professionals. Key words relevant to JIA were searched across 10 search engines. Quality of information was appraised independently by 2 health professionals, 1 young adult with JIA, and a parent using the DISCERN tool. Concordance of the website content (i.e., accuracy and completeness) with available evidence about the management of JIA was determined. Readability was determined using Flesch-Kincaid grade level and Reading Ease Score. Out of the 3000 Web pages accessed, only 58 unique sites met the inclusion criteria. Of these sites only 16 had DISCERN scores above 50% (indicating fair quality). These sites were then rated by consumers. Most sites targeted parents and none were specifically developed for youth with JIA. The overall quality of website information was fair, with a mean DISCERN quality rating score of 48.92 out of 75 (+/- 6.56, range 34.0-59.5). Overall completeness of sites was 9.07 out of 16 (+/- 2.28, range 5.25-13.25) and accuracy was 3.09 out of 4 (+/- 0.86, range 2-4), indicating a moderate level of accuracy. Average Flesch-Kincaid grade level and Reading Ease Score were 11.48 (+/- 0.74, range 10.1-12.0) and 36.36 (+/- 10.86, range 6.30-48.1), respectively, indicating that the material was difficult to read. Our study highlights the paucity of high quality Internet health information at an appropriate reading level for youth with JIA and their parents.

Recently, there has been considerable effort to promote the use of health information technology (HIT) in order to improve health care quality. However, relatively little is known about the extent to which HIT implementation is associated with hospital patient care quality. We undertook this study to determine the association of various HITs with: hospital quality improvement (QI) practices and strategies; adherence to process of care measures; risk-adjusted inpatient mortality; patient satisfaction; and assessment of patient care quality by hospital quality managers and front-line clinicians. We conducted surveys of quality managers and front-line clinicians (physicians and nurses) in 470 short-term, general hospitals to obtain data on hospitals' extent of HIT implementation, QI practices and strategies, assessments of quality performance, commitment to quality, and sufficiency of resources for QI. Of the 470 hospitals, 401 submitted complete data necessary for analysis. We also developed measures of hospital performance from several publicly data available sources: Hospital Compare adherence to process of care measures; Medicare Provider Analysis and Review (MEDPAR) file; and Hospital Consumer Assessment of Healthcare Providers and Systems HCAHPS® survey. We used Poisson regression analysis to examine the association between HIT implementation and QI practices and strategies, and general linear models to examine the relationship between HIT implementation and hospital performance measures. Controlling for potential confounders, we found that hospitals with high levels of HIT implementation engaged in a statistically significant greater number of QI practices and strategies, and had significantly better performance on mortality rates, patient satisfaction measures, and assessments of patient care quality by hospital quality managers; there was weaker evidence of higher assessments of patient care quality by front-line clinicians.

The quality of data in public health information systems can be ensured by effective data quality assessment. In order to conduct effective data quality assessment, measurable data attributes have to be precisely defined. Then reliable and valid measurement methods for data attributes have to be used to measure each attribute. We conducted a systematic review of data quality assessment methods for public health using major databases and well-known institutional websites. 35 studies were eligible for inclusion in the study. A total of 49 attributes of data quality were identified from the literature. Completeness, accuracy and timeliness were the three most frequently assessed attributes of data quality. Most studies directly examined data values. This is complemented by exploring either data users' perception or documentation quality. However, there are limitations of current data quality assessment methods: a lack of consensus on attributes measured; inconsistent definition of the data quality attributes; a lack of mixed methods for assessing data quality; and inadequate attention to reliability and validity. Removal of these limitations is an opportunity for further improvement.

To evaluate the quality of information available on the Internet to patients with a cervical pathology undergoing elective cervical spine surgery. Six key words ("cervical discectomy," "cervical foraminotomy," "cervical fusion," "cervical disc replacement," "cervical arthroplasty," "cervical artificial disc") were entered into two different search engines (Google, Yahoo!). For each key word, the first 50 websites were evaluated for accessibility, comprehensibility, and website quality using the DISCERN tool, transparency and honesty criteria, and an accuracy and exhaustivity scale. Of 5,098,500 evaluable websites, 600 were visited; 97 (16%) of these websites were evaluated for quality and comprehensiveness. Overall, 3% of sites obtained an excellent global quality score, 7% obtained a good score, 25% obtained an above average score, 15% obtained an average score, 37% obtained a poor score, and 13% obtained a very poor score. High-quality websites were affiliated with a professional society (P = 0.021), had bibliographical references (P = 0.030), and had a recent update within 6 months (r = 0.277, P < 0.001). No correlation between global quality score and other variables was observed. This study shows that the search for medical information on the Internet is time-consuming and often disappointing. The Internet is a potentially misleading source of information. Surgeons and professional societies must use the Internet as an ally in providing optimal information to patients. Copyright © 2014.

Machining status monitoring technique by multi-sensors can acquire and analyze the machining process information to implement abnormity diagnosis and fault warning. Statistical quality control technique is normally used to distinguish abnormal fluctuations from normal fluctuations through statistical method. In this paper by comparing the advantages and disadvantages of the two methods, the necessity and feasibility of integration and fusion is introduced. Then an approach that integrates multi-sensors status monitoring and statistical process control based on artificial intelligent technique, internet technique and database technique is brought forward. Based on virtual instrument technique the author developed the machining quality assurance system - MoniSysOnline, which has been used to monitoring the grinding machining process. By analyzing the quality data and AE signal information of wheel dressing process the reason of machining quality fluctuation has been obtained. The experiment result indicates that the approach is suitable for the status monitoring and analyzing of machining process.

It is the aim of the current research to identify some common functionalities of postnatal application, and to determine the quality of the information content of postnatal depression application using validated scales that have been applied for applications in other specialties. To determine the information quality of the postnatal depression smartphone applications, the two most widely used smartphone application stores, namely Apple iTunes as well as Google Android Play store, were searched between 20May and 31 May. No participants were involved. The inclusion criteria for the application were that it must have been searchable using the keywords 'postnatal', 'pregnancy', 'perinatal', 'postpartum' and 'depression', and must be in English language. The Silberg Scale was used in the assessment of the information quality of the smartphone applications. The information quality score was the primary outcome measure. Our current results highlighted that while there is currently a myriad of applications, only 14 applications are specifically focused on postnatal depression. In addition, the majority of the currently available applications on the store have only disclosed their last date of modification as well as ownership. There remain very limited disclosures about the information of the authors, as well as the references for the information included in the application itself. The average score for the Silberg Scale for the postnatal applications we have analysed is 3.0. There remains a need for healthcare professionals and developers to jointly conceptualise new applications with better information quality and evidence base. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Evaluating the quality and readability of Internet information sources regarding the treatment of swallowing disorders.

PubMed

O'Connell Ferster, Ashley P; Hu, Amanda

2017-03-01

The Internet has become a popular resource for patient education. The information it provides, however, is rarely peer-reviewed, and its quality may be a concern. Since the average American reads at an 8th grade level, the American Medical Association and the National Institutes of Health have recommended that health information be written at a 4th to 6th grade level. We performed a study to assess the quality and readability of online information regarding the treatment of swallowing disorders. A Google search for "swallowing treatment" was conducted. We studied the first 50 websites that appeared on the search engine's results with the use of the DISCERN quality index tool, the Flesch Ease of Reading Score (FRES), and the Flesch-Kincaid Grade Level (FKGL) readability test. DISCERN is a validated 16-item questionnaire used to assess the quality of written health information; FRES and FKGL are used to assess readability. We classified the websites as either patient-targeted or professional-targeted sites, as well as either major or minor. The overall DISCERN score was 1.61 ± 0.61 (range: 1 to 5), the overall FRES was 39.1 ± 19.0 (range: 1 to 100), and the overall FKGL was 11.8 ± 3.4 (range: 3 to 12). As would be expected, patient-targeted websites had significantly higher FRES and significantly lower FKGL scores than did the professional-targeted websites (p = 0.01 and p = 0.04, respectively); there was no significant difference between the two in DISCERN scores. The major websites had significantly higher DISCERN scores than did the minor sites (p = 0.002); there were no significant differences in FRES and FKGL scores. We conclude that online information sources regarding the treatment of swallowing disorders were of suboptimal quality in that information was written at a level too difficult for the average American to easily understand. Also, the patient-targeted websites were written at a lower reading level, and the major websites contained a higher quality

As the number of older adults turning to the Internet for health information increases, so does the potential for online information to have a substantial impact on the patient-physician relationship and on their health. Inaccurate information may weaken patient-physician relationships or result in increased physician visits and health anxiety, while high quality information may allow Internet users to make better decisions about their health. To assess the quality and content of available online resources about the prevention of Alzheimer's disease (AD). A sample of 308 articles related to the prevention of AD was collected from the first three pages of location-independent keyword searches on Google.com between September 17-30, 2014. Content analysis was applied to articles that met criteria (n = 298) and a quality evaluation tool was developed to generate a quality score for each of the articles (n = 290). We found that articles on the high end of the quality spectrum focused on modifiable risk factors and tended to present balanced information, while articles of low quality emphasized nutrition as a method of prevention and were more likely to be in conflict of interest. This study provides the first insight into the content and quality of prevention information for AD currently available online and highlights the importance of future research to better understand the impact of this information on the patient-physician relationship and health decision-making of older adults.

Objective We evaluate the effects of the Nursing Home Quality Initiative (NHQI), which introduced quality measures to the Centers for Medicare and Medicaid Services' Nursing Home Compare website, on facility performance and consumer demand for services. Data Sources The nursing home Minimum Data Set facility reports from 1999 to 2005 merged with facility-level data from the On-Line Survey, Certification, and Reporting System. Study Design We rely on the staggered rollout of the report cards across pilot and nonpilot states to examine the effect of report cards on market share and quality of care. We also exploit differences in nursing home market competition at baseline to identify the impacts of the new information on nursing home quality. Results The introduction of the NHQI was generally unrelated to facility quality and consumer demand. However, nursing homes facing greater competition improved their quality more than facilities in less competitive markets. Conclusions The lack of competition in many nursing home markets may help to explain why the NHQI report card effort had a minimal effect on nursing home quality. With the introduction of market-based reforms such as report cards, this result suggests policy makers must also consider market structure in efforts to improve nursing home performance.

Shared facilities are not recognised as improved sanitation due to challenges of maintenance as they easily can be avenues for the spread of diseases. Thus there is need to evaluate the quality of shared facilities, especially in informal settlements, where they are commonly used. A shared facility can be equated to a common good whose management depends on the users. If users do not work collectively towards keeping the facility clean, it is likely that the quality may depreciate due to lack of maintenance. This study examined the quality of shared sanitation facilities and used the common pool resource (CPR) management principles to examine the determinants of shared sanitation quality in the informal settlements of Kisumu, Kenya. Using a multiple case study design, the study employed both quantitative and qualitative methods. In both phases, users of shared sanitation facilities were interviewed, while shared sanitation facilities were inspected. Shared sanitation quality was a score which was the dependent variable in a regression analysis. Interviews during the qualitative stage were aimed at understanding management practices of shared sanitation users. Qualitative data was analysed thematically by following the CPR principles. Shared facilities, most of which were dirty, were shared by an average of eight households, and their quality decreased with an increase in the number of households sharing. The effect of numbers on quality is explained by behaviour reflected in the CPR principles, as it was easier to define boundaries of shared facilities when there were fewer users who cooperated towards improving their shared sanitation facility. Other factors, such as defined management systems, cooperation, collective decision making, and social norms, also played a role in influencing the behaviour of users towards keeping shared facilities clean and functional. Apart from hardware factors, quality of shared sanitation is largely due to group behaviour of users

The use of publicly available quality information when choosing a hospital or health-care provider: the role of the GP.

Patients barely use publicly available quality information for making a decision concerning secondary health care, but instead rely on information coming from their general practitioner (GP). An intermediate role of GPs has been suggested concerning the use of publicly available quality information. The aim of the study is to quantify and explore GPs' use of publicly available quality information when referring patients or suggesting secondary health-care provider to them. In this cross-sectional study, an invitation to an electronic questionnaire was sent to 858 GPs in the south of the Netherlands. GPs were asked about their use of and perception towards publicly available quality information through closed-ended and open-ended questions. Differences among subgroups were tested for significance using Pearson's chi-square tests. The majority of respondents (89.5%) never or rarely use publicly available quality information. They perceive them as invalid and unreliable. Distance to the hospital, prior experiences and personal contacts with specialists guide them when advising and referring. Almost 90% of respondents never or rarely suggest quality information as support for decision making to their patients. No significant differences between subgroups were observed. This study is among the firsts exploring and quantifying GPs' use of publicly available quality information. The results suggest that publicly available quality information appears in its current format and application not useful for GPs. GPs have to be aware of their influential role in patients' decision making and possibly have to take more responsibility in guiding them through the jungle of quality information. © 2014 John Wiley & Sons Ltd.

The adoption of health information technology has been recommended as a viable mechanism for improving quality of care and patient health outcomes. However, the capacity of health information technology (i.e., availability and use of multiple and advanced functionalities), particularly in federally qualified health centers (FQHCs) on improving quality of care is not well understood. We examined associations between health information technology (HIT) capacity at FQHCs and quality of care, measured by the receipt of discharge summary, frequency of patients receiving reminders/notifications for preventive care/follow-up care, and timely appointment for specialty care. The analyses used 2009 data from the National Survey of Federally Qualified Health Centers. The study included 776 of the FQHCs that participated in the survey. We examined the extent of HIT use and tested the hypothesis that level of HIT capacity is associated with quality of care. Multivariable logistic regressions, reporting unadjusted and adjusted odds ratios, were used to examine whether 'FQHCs' HIT capacity' is associated with the outcome measures. The results showed a positive association between health information technology capacity and quality of care. FQHCs with higher HIT capacity were significantly more likely to have improved quality of care, measured by the receipt of discharge summaries (OR=1.43; CI=1.01, 2.40), the use of a patient notification system for preventive and follow-up care (OR=1.74; CI=1.23, 2.45), and timely appointment for specialty care (OR=1.77; CI=1.24, 2.53). Our findings highlight the promise of HIT in improving quality of care, particularly for vulnerable populations who seek care at FQHCs. The results also show that FQHCs may not be maximizing the benefits of HIT. Efforts to implement HIT must include strategies that facilitate the implementation of comprehensive and advanced functionalities, as well as promote meaningful use of these systems.

Increasing investment in eHealth aims to improve cost effectiveness and safety of care. Data extraction and aggregation can create new data products to improve professional practice and provide feedback to improve the quality of source data. A previous systematic review concluded that locally relevant clinical indicators and use of clinical record systems could support clinical governance. We aimed to extend and update the review with a theoretical framework. We searched PubMed, Medline, Web of Science, ABI Inform (Proquest) and Business Source Premier (EBSCO) using the terms curation, information ecosystem, data quality management (DQM), data governance, information governance (IG) and data stewardship. We focused on and analysed the scope of DQM and IG processes, theoretical frameworks, and determinants of the processing, quality assurance, presentation and sharing of data across the enterprise. There are good theoretical reasons for integrated governance, but there is variable alignment of DQM, IG and health system objectives across the health enterprise. Ethical constraints exist that require health information ecosystems to process data in ways that are aligned with improving health and system efficiency and ensuring patient safety. Despite an increasingly 'big-data' environment, DQM and IG in health services are still fragmented across the data production cycle. We extend current work on DQM and IG with a theoretical framework for integrated IG across the data cycle. The dimensions of this theory-based framework would require testing with qualitative and quantitative studies to examine the applicability and utility, along with an evaluation of its impact on data quality across the health enterprise.

Investigators aimed to assess online information describing uterine artery embolization (UAE) to examine the quality and readability of websites patients are accessing. A list of applicable, commonly used searchable terms was generated, including "Uterine Artery Embolization," "Fibroid Embolization," "Uterine Fibroid Embolization," and "Uterine Artery Embolisation." Each possible term was assessed across the five most-used English language search engines to determine the most commonly used term. The most common term was then investigated across each search engine, with the first 25 pages returned by each engine included for analysis. Duplicate pages, nontext content such as video or audio, and pages behind paywalls were excluded. Pages were analyzed for quality and readability using validated tools including DISCERN score, JAMA Benchmark Criteria, HONcode Certification, Flesch Reading Ease Score, Flesch-Kincaid Grade Level, and Gunning-Fog Index. Secondary features such as age, rank, author, and publisher were recorded. The most common applicable term was "Uterine Artery Embolization" (492,900 results). Mean DISCERN quality of information provided by UAE websites is "fair"; however, it has declined since comparative 2012 studies. Adherence to JAMA Benchmark Criteria has reduced to 6.7%. UAE website readability remains more difficult than the World Health Organization-recommended 7-8th grade reading levels. HONcode-certified websites (35.6%) demonstrated significantly higher quality than noncertified websites. Quality of online UAE information remains "fair." Adherence to JAMA benchmark criteria is poor. Readability is above recommended 7-8th grade levels. HONcode certification was predictive of higher website quality, a useful guide to patients requesting additional information. Copyright © 2018 The Association of University Radiologists.

[The external evaluation of study quality: the role in maintaining the reliability of laboratory information].

PubMed

Men'shikov, V V

2013-08-01

The external evaluation of quality of clinical laboratory examinations was gradually introduced in USSR medical laboratories since 1970s. In Russia, in the middle of 1990 a unified all-national system of external evaluation quality was organized known as the Federal center of external evaluation of quality at the basis of laboratory of the state research center of preventive medicine. The main positions of policy in this area were neatly formulated in the guidance documents of ministry of Health. Nowadays, the center of external evaluation of quality proposes 100 and more types of control studies and permanently extends their specter starting from interests of different disciplines of clinical medicine. The consistent participation of laboratories in the cycles of external evaluation of quality intrinsically promotes improvement of indicators of properness and precision of analysis results and increases reliability of laboratory information. However, a significant percentage of laboratories does not participate at all in external evaluation of quality or takes part in control process irregularly and in limited number of tests. The managers of a number of medical organizations disregard the application of the proposed possibilities to increase reliability of laboratory information and limit financing of studies in the field of quality control. The article proposes to adopt the national standard on the basis of ISO 17043 "Evaluation of compliance. The common requirements of professional competence testing".

The aim of this study was to investigate the association between cancer patients' ability to share information about their illness with their social network and attachment style dimensions, alexithymia, and quality of life. We hypothesised that ability to share information about one's cancer with family, friends, and medical teams would be positively associated with quality of life and secure attachment and negatively associated with alexithymia. Forty-five cancer patients were recruited from the Psycho-oncology Unit of the San Camillo-Forlanini Hospital in Rome. We collected anamnestic data and self-report data on social sharing ability, quality of life, alexithymia, and attachment. Sharing with family (B = 4.66; SE = 1.82; β = .52; SE = 0.20; t(41) = 2.6; P = .0143) was the only predictor of global health status, and attachment security was the only predictor of mean social sharing (B = 0.25; SE = 0.06; β = .63; SE = 0.14; t(41) = 4.4; P < .0001). Encouraging patients to share information about their experience of cancer may help to improve their quality of life. Attachment security seems to promote social sharing. Psychological assessments of cancer patients should cover both ability to share information about one's cancer with family and attachment security. Copyright © 2016 John Wiley & Sons, Ltd.

A robust quality-assurance program is essential for laboratories that perform molecular genetic testing to maintain high-quality testing and be able to address challenges associated with performance or delivery of testing services as the use of molecular genetic tests continues to expand in clinical and public health practice. This unit discusses quality-assurance and quality-improvement considerations that are critical for molecular genetic testing performed for heritable diseases and conditions. Specific discussion is provided on applying regulatory standards and best practices in establishing/verifying test performance, ensuring quality of the total testing process, monitoring and maintaining personnel competency, and continuing quality improvement. The unit provides a practical reference for laboratory professionals to use in recognizing and addressing essential quality-assurance issues in human molecular genetic testing. It should also provide useful information for genetics researchers, trainees, and fellows in human genetics training programs, as well as others who are interested in quality assurance and quality improvement for molecular genetic testing. 2011 by John Wiley & Sons, Inc.

This report presents a science strategy for the third decade of the National Water-Quality Assessment (NAWQA) Program, which since 1991, has been responsible for providing nationally consistent information on the quality of the Nation's streams and groundwater; how water quality is changing over time; and the major natural and human factors that affect current water quality conditions and trends. The strategy is based on an extensive evaluation of the accomplishments of NAWQA over its first two decades, the current status of water-quality monitoring activities by USGS and its partners, and an updated analysis of stakeholder priorities. The plan is designed to address priority issues and national needs identified by NAWQA stakeholders and the National Research Council (2012) irrespective of budget constraints. This plan describes four major goals for the third decade (Cycle 3), the approaches for monitoring, modeling, and scientific studies, key partnerships required to achieve these goals, and products and outcomes that will result from planned assessment activities. The science plan for 2013–2023 is a comprehensive approach to meet stakeholder priorities for: (1) rebuilding NAWQA monitoring networks for streams, rivers, and groundwater, and (2) upgrading models used to extrapolate and forecast changes in water-quality and stream ecosystem condition in response to changing climate and land use. The Cycle 3 plan continues approaches that have been central to the Program’s long-term success, but adjusts monitoring intensities and study designs to address critical information needs and identified data gaps. Restoration of diminished monitoring networks and new directions in modeling and interpretative studies address growing and evolving public and stakeholder needs for water-quality information and improved management, particularly in the face of increasing challenges related to population growth, increasing demands for water, and changing land use and climate

Surfing for back pain patients: the nature and quality of back pain information on the Internet.

A prospective, systematic review of web sites related to back pain. To assess the nature and quality of back pain-related information on the World Wide Web during a 2-year period. The Internet has become a rich source of medical information. Limited knowledge is available, however, about the quality of online resources. Although previous systematic reviews on medical-related web sites found problems in varying degrees with the credibility of information, no such review was conducted to assess the back pain-related sites. A search of web sites was conducted in November 1996 using five search engines (AltaVista, Infoseek, Lycos, Yahoo, and Magellan) and two key terms ("back pain" and "back problems"). A sample of sites was evaluated by two independent reviewers. Each site was described by the type and nature of the sponsor, target audience, and content. Overall quality was assessed in terms of evidence-based information available. Seventy-four web sites were reviewed in 1996, and nine of them (12.2%) were identified as high-quality sites. Advertising was the focus of 80.8% of the sites. Eleven sites (14.9%) were found to be discontinued 1 year later, and 20 (27.0%) were not accessible by the reviewers at the 2-year follow-up evaluation. Of the remaining 54 sites, 44.4% were produced by for-profit companies, and most sites targeted people with back pain (63.0%). Only seven out of the nine high-quality sites held their ratings at the 2-year follow-up evaluation. Most back pain-related web sites can be classified as advertising. The quality varied considerably, resulting in difficulties for patients to find useful information in this field. The increasing number of people seeking medical information on the Web creates a need for more high quality sites. Further, systematic review of web sites should be encouraged to monitor the accuracy of Internet publication.
