Putting the “learning” in “pre-learning”: effects of a self-directed study hall on skill acquisition in a simulation-based central line insertion course

Abstract

AbstractBackgroundOpportunities to practice procedural skills in the clinical learning environment are decreasing, and faculty time to coach skills is limited, even in simulation-based training. Self-directed learning with hands-on practice early in a procedural skill course might help maximize the benefit of later faculty coaching and clinical experience. However, it may also lead to well-learned errors if learners lack critical guidance. The present study sought to investigate the effects of a hands-on, self-directed “study hall” for central line insertion among first-year residents.MethodsLearner cohorts before vs. after introduction of the study hall (n = 49) were compared on their pre- and post-test performance of key procedural behaviors that were comparable across cohorts, with all learners receiving traditional instructor-led training between tests.ResultsStudy hall participants spent a median of 116 min in hands-on practice (range 57–175). They scored higher at pre-test (44% vs. 27%,p = .00; Cohen’sd = 0.95) and at post-test (80% vs. 72%,p = .02; Cohen’sd = 0.69). A dose–response relationship was found, such that 2 h of study hall were roughly equivalent to the performance improvement seen with four clinical observations or supervised insertions of central lines.ConclusionsSelf-directed, hands-on “study hall” supported improved procedural skill learning in the context of limited faculty availability. Potential additional benefits make the approach worth further experimentation and evaluation.
