Ascertaining top evidence in emergency medicine: A modified Delphi study

OBJECTIVES: The application of evidence-informed practice in emergency medicine (EM) is critical to improve the quality of patient care. EM is a specialty with a broad knowledge base making it daunting for a junior resident to know where to begin the acquisition of evidence-based knowledge. Our study's objective was to formulate a list of "top papers" in the field of EM using a Delphi approach to achieve an expert consensus. METHODS: Participants were recruited from all 14 specialty EM programs across Canada by a nomination process by the program directors. The modified Delphi survey consisted of three study rounds, each round sent out via email. The study tool was piloted first with McMaster University's specialty EM residents. During the first round, participants individually listed top papers relevant to EM. During the two subsequent rounds, participants ranked the papers listed in the first round, with a chance to adjust ranking based on group responses. RESULTS: A total of eight EM specialty programs responded with 30 responses across the three rounds. There were 119 studies suggested in the first round, and, by the third round, a consensus of>70% agreement was reached to generate the final list of 29 studies. CONCLUSIONS: We produced, via an expert consensus, a list of top studies relevant for Canadian EM physicians in training. It can be used as an educational resource for junior residents as they transition into practice.
