What is an hour-lecture worth?

Background Although there are many ways to convey knowledge, attitudes, and techniques when teaching residents and students, the most optimal method (lecture, online lecture, online tutorial, simulator practice, and so on) is yet to be determined. Methods This study was designed to be a prospective analysis of change in resident behavior, and the model chosen was resident compliance with alcohol screening during admissions to the trauma service. Baseline values were determined the month before the educational “intervention,” which was planned to be a 1-hour lecture during Grand Rounds on the importance of screening for alcohol disuse syndromes. After the “intervention,” results were analyzed at 3 points in time: during the first month after the lecture and then at 3 and 12 months. Results Resident compliance with alcohol usage screening rose from 53% at baseline to 80% at 1 year. Conclusions This straightforward model of utility of a lecture showed a significant change in resident behavior.
