OBJECTIVE(S): The Advanced Trauma Life Support (ATLSŪ) course is the American College of Surgeons (ACS) standard of care for physicians who provide initial care to trauma victims. ATLSŪ version 10 was developed to adopt contemporary learning theory and practice into the format and conduct of the training. The purpose of this study is to understand how training format and conduct changes are associated with student performance on the student and student refresher courses in the 10th relative to the 9th version.
METHODS: The study unfolded as a natural experiment and employed a mixed-methods approach wherein a one-group posttest-only quantitative study was followed up with a faculty survey to qualitatively explore the quantitative findings. the statistical analysis included the Wilcoxon-Mann-Whitney U Test and the Chi Squared analysis of variance; the power threshold of 0.95 was achieved.
RESULTS: Across 27 student and 20 student refresher courses taught at one site in 2018 and 2019 (over 400 students per year), student and student refresher written test scores and initial assessment pass rates were not associated with statistically significant improvement. Further, ATLSŪ version 10 student and student refresher courses were associated with higher student costs and less faculty interest in teaching the course relative to version 9.
CONCLUSIONS: It may be prudent to consider additional evidence of improved student performance and training value before implementing changes to the format and conduct of the training for the next quadrennial review of the content, format and conduct of ATLSŪ student and student refresher courses.
