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

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

Studies analysing the need for health-related information in Germany - a systematic review

BACKGROUND: Exploring health-related information needs is necessary to better tailor information. However, there is a lack of systematic knowledge on how and in which groups information needs has been assessed, and which information needs have been identified. We aimed to assess the methodology of studies used to assess information needs, as well as the topics and extent of health-related information needs and associated factors in Germany. METHODS: A systematic search was performed in Medline, Embase, Psycinfo, and all databases of the Cochrane Library. All studies investigating health-related information needs in patients, relatives, and the general population in Germany that were published between 2000 and 2012 in German or English were included. Descriptive content analysis was based on predefined categories. RESULTS: We identified 19 studies. Most studies addressed cancer or rheumatic disease. Methods used were highly heterogeneous. Apart from common topics such as treatment, diagnosis, prevention and health promotion, etiology and prognosis, high interest ratings were also found in more specific topics such as complementary and alternative medicine or nutrition. Information needs were notable in all surveyed patient groups, relatives, and samples of the general population. Younger age, shorter duration of illness, poorer health status and higher anxiety and depression scores appeared to be associated with higher information needs. CONCLUSION: Knowledge about information needs is still scarce. Assuming the importance of comprehensive information to enable people to participate in health-related decisions, further systematic research is required

Information needs in people with diabetes mellitus: a systematic review

Abstract Background The purpose of this study was to identify and analyse currently available knowledge on information needs of people with diabetes mellitus, also considering possible differences between subgroups and associated factors. Methods Twelve databases including MEDLINE, EMBASE and the Cochrane Library were searched up until June 2015. Publications that addressed self-reported information needs of people with diabetes mellitus were included. Each study was assessed by using critical appraisal tools, e.g. from the UK National Institute for Health and Care Excellence. Extraction and content analysis were performed systematically. Results In total, 1993 publications were identified and 26 were finally included. Nine main categories of information needs were identified, including ‘treatment-process’, ‘course of disease’, ‘abnormalities of glucose metabolism’ and ‘diabetes through the life cycle’. Differences between patient subgroups, such as type of diabetes or age, were sparsely analysed. Some studies analysed associations between information needs and factors such as participation preferences or information seeking. They found, for example, that information needs on social support or life tasks were associated with information seeking in Internet forums. Conclusion Information needs in people with diabetes mellitus, appear to be high, yet poorly investigated. Research is needed regarding differences between diverse diabetes populations, including gender aspects or changes in information needs during the disease course. Systematic review registration The review protocol has been registered at Prospero (CRD42015029610)
