Abstract 250: Effect of a Single First 4 Minutes BLS Training Session on BLS Skills Acquisition and 6-Month Retention for First-Year Medical Students
Introduction: First 4 Minutes (FFM) incorporates experiential learning and real-time problem solving using simulated emergencies that require individuals to work collaboratively for success. This study examined the effect of a Basic Life Support-based FFM exercise on novice students’ BLS individual and team skill acquisition and retention.
Method: 41 first year medical students were randomly assigned to teams in one of 2 groups. All participants had completed and passed a standard classroom BLS course including lecture, manikin practice and written exam and manikin-based skills test. The experimental groups then participated in a FFM-BLS training session using a feedback manikin (Laerdal ACS manikin with PC skills reporting software). Students’ BLS skills were compared using the associated computer software on day 1 with and without the FFM-BLS training at baseline and again 6 months later on the same manikin. Individual performance of chest compressions was compared for all participants. Group code response data (time to first AED shock, first shock pause, total hands off time during code, and percent of correct depth of compression) as well as subjective teamwork analysis scores were measured. Statistical analysis was performed using a Signed Rank Test and Wilcoxon Rank Sum Test.
Results: Initial performance in BLS simulation prior to the FFM-BLS activity was similar. Analysis of individual data both immediately after the BLS course with or without FFM-BLS and at 6 months showed a significantly increased percentage of correct depth of compression (p=0.006 & 0.016) and of average depth (p=0.008 & 0.012) in the FFM-BLS group compared with the control group. Group code response data and teamwork analysis scores were significantly better in the experimental group on day 1 but only showed a trend toward better performance in the experimental group at 6 months in this small sample.
Conclusion: Supplemental simulation training using the FFM approach is associated with improved acquisition and retention of individual and teamwork BLS skills by first year medical students and should be considered to enhance their acquisition of these skills.
