Evidence-based guidelines have been developed as a strategy to synthesise current research and develop recommendations designed to help clinicians make decisions about patient management within specific clinical contexts.1 Such synthesis is needed to support time and resource poor clinicians to ensure that their clinical practice reflects the best available evidence. In many, but not all, cases guidelines have been rigorously developed and evaluated, most commonly against the Appraisal of Guidelines for Research & Evaluation II appraisal guidelines (AGREE II).2 The inclusion of high quality research in systematically developed clinical practice guidelines is one strategy thought to help ensure delivery of evidence-based clinical care. However, the presence of guidelines themselves does not ensure that the research is implemented into clinical practice. We also do not know which strategies are likely to be best in disseminating and implementing guideline recommendations.
