Bottom Line: Thus we developed a web-based EBPI and aim to evaluate its effects on informed decision making in people 50 years or older.We expect better informed participants in the intervention group.The design of this study may be a prototype for other web-based prevention information and their evaluation.

ABSTRACT

Background: Evidence-based patient information (EBPI) has been recognised as important tool for informed choice in particular in the matter of preventive options. An objective, on the best scientific evidence-based consumer information about subthreshold elevated blood glucose levels (impaired fasting glucose and impaired glucose tolerance) and primary prevention of diabetes, is not available yet. Thus we developed a web-based EBPI and aim to evaluate its effects on informed decision making in people 50 years or older.

Methods/design: We conduct a web-based randomised-controlled trial to evaluate the effect of information about elevated blood glucose levels and diabetes primary prevention on five specific outcomes: (i) knowledge of elevated blood glucose level-related issues (primary outcome); (ii) attitudes to a metabolic testing; (iii) intention to undergo a metabolic testing; (iv) decision conflict; (v) satisfaction with the information. The intervention group receives a specially developed EBPI about subthreshold elevated blood glucose levels and diabetes primary prevention, the control group information about this topic, available in the internet.The study population consists of people between 50 and 69 years of age without known diabetes. Participants will be recruited via the internet page of the cooperating health insurance company, Techniker Krankenkasse (TK), and the internet page of the German Diabetes Centre. Outcomes will be measured through online questionnaires. We expect better informed participants in the intervention group.

Discussion: The design of this study may be a prototype for other web-based prevention information and their evaluation.

Trial registration: Current Controlled Trial: ISRCTN22060616.

Figure 1: Progress of intervention.

Mentions: Participants obtain the internet information (EBPI or standard, respectively) on blood glucose disorders, metabolic testing (diabetes-testing) and prevention strategies. The survey is carried out at three points in time (T0/T1, T2), with the first two times during one visit to the website. T0 or T1 is the questioning before or after reading the information, so that the gain of knowledge and a characterisation of later drop-outs is ascertainable. T2 is the online follow-up survey two weeks after the first online session (see Figure 1).
