Introduction: Simulation-based medical education allows learners to refine and maintain clinical skills especially for high-stake situations such as trauma resuscitation. Despite the primary and secondary survey being its foundation, literature shows poor adherence with overall rates as low as 13%. This study evaluates the impact of rapid cycle deliberate practice (RCDP) on primary and secondary survey skill retention. We hypothesized that RCDP-trained surgery residents will have real-world clinical improvement in their survey completion in pediatric trauma resuscitations. Methods: We developed an RCDP trauma resuscitation curriculum. Videos of trauma resuscitations before and after curriculum implementation were scored by 2 blinded reviewers using a modified Pediatric Trauma Assessment Scoring Tool. Actual trauma care by residents who had received the curriculum (study group) was compared with care provided by residents who had not received the curriculum (precurriculum historical control group and a concurrent control group who provided care without receiving the curriculum). Results: One hundred eighty-eight videos were scored with 98 in study group, 33 in concurrent control group, and 57 in historical control group. There was a significant improvement in primary survey performance between study group and historical control group (P < 0.001), but no difference between study group and concurrent control group. There was a significant improvement between study group and 2 control groups in secondary survey performance (both P < 0.001). Conclusions: The RCDP curriculum led to significant improvement in surgical residents' trauma survey performance and had clinical impact on actual patients, which is rare in pediatric trauma simulation literature.
