OBJECTIVES: Surveys can provide important information about what people think or do. There is little guidance about how to use surveys in decision making. This article provides guidance for how to appraise and use a survey to answer health care questions. STUDY DESIGN AND SETTING: A guidance paper about the use a survey of a selected sample of people, who completed a self-report tool about their knowledge, beliefs and opinions, behaviours and experiences, or personal attributes. We use survey examples, one scenario and a specific survey for illustration. RESULTS: Decision makers should consider the credibility and applicability of the results of a survey. Key threats to credibility depend on the representativeness of the population and likelihood that it provides an accurate picture of the population's knowledge, attitudes or self-reported practices. If survey investigators do not use rigorous strategies to develop or pre-test questions, there is a greater risk that results will be misleading. Decision makers may want to consider the precision of estimates and whether it would change their decisions. Finally, they need to decide how similar the surveyed population is to their specific population before applying results. CONCLUSIONS: Decision makers can follow this guidance to critically appraise, interpret and apply results of surveys to health care questions.
