44‐55‐66‐PM, a Mnemonic That Improves Retention of the Ottawa Ankle and Foot Rules: A Randomized Controlled Trial

Abstract

Mid-term knowledge of the OAR drastically improved for all participants of the study. The use of the mnemonic 44-55-66-PM was associated with a better long-term knowledge of the OAR among medical students and residents. The improvement in knowledge of the OAR among the control group highlights the importance of using controlled trials for studies evaluating knowledge transfer.
