Hybrid Delivery of ATLS Maintains Learner Outcomes

To compare learner outcomes and satisfaction between traditional in-person and hybrid Advanced Trauma Life Support (ATLS) 10th Edition course formats. We hypothesized that the hybrid model would maintain learner performance without compromising satisfaction.

Retrospective cohort study comparing pre- and post-test scores and postcourse survey responses from ATLS participants at 2 sites between January 2021 and December 2024. Data were analyzed using 2-tailed t-tests.

Two Level I trauma centers and academic teaching hospitals offering ATLS courses-one using a traditional in-person format, and the other a hybrid format incorporating asynchronous online modules with a shortened in-person session.

A total of 649 learners were included (370 hybrid; 279 traditional). All completed both pre- and post-tests; 197 learners (63 hybrid; 134 traditional) completed postcourse surveys. Participants included physicians, resident physicians, advanced practice providers, and certified nurse anesthetists. Resident physicians were present only in the hybrid cohort.

Learners in the hybrid group had lower pretest scores (median 78 vs. 80, p = 0.037) but higher post-test scores (median 90 vs. 85, p < 0.001) compared to the traditional group. Survey responses showed no significant differences between cohorts in perceived competence, communication, or overall satisfaction.

Hybrid ATLS delivery was noninferior to traditional models when comparing post-test scores and learner satisfaction. These findings support the use of hybrid formats in trauma education and suggest potential benefits in scalability and accessibility. Further research is needed to assess long-term retention and cost-effectiveness.
