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

循证患者信息（EBPI）已被认为是在预防选择方面做出明智选择的重要工具。目前尚缺乏针对亚阈值升高的血糖水平（空腹血糖受损和糖耐量受损）和糖尿病初级预防的客观的、基于最佳科学证据的消费者信息。因此，我们开发了一种基于网络的 EBPI，并旨在评估其对 50 岁及以上人群做出明智决策的影响。
方法/设计：我们进行了一项基于网络的随机对照试验，以评估有关升高的血糖水平和糖尿病初级预防的信息对五个具体结果的影响：（i）与升高的血糖水平相关问题的知识（主要结果）；（ii）对代谢测试的态度；（iii）进行代谢测试的意向；（iv）决策冲突；（v）对信息的满意度。干预组接受专门开发的关于亚阈值升高的血糖水平和糖尿病初级预防的 EBPI，对照组则提供互联网上有关该主题的信息。研究人群包括年龄在 50 至 69 岁之间、无已知糖尿病的人群。参与者将通过合作健康保险公司 Techniker Krankenkasse（TK）的互联网页面和德国糖尿病中心的互联网页面招募。通过在线问卷来衡量结果。我们预计干预组的参与者会有更好的信息。
本研究的设计可能是其他基于网络的预防信息及其评估的原型。
