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.
