The RCDP group had a higher mean Resident Team Leader Evaluation score (0.54 ± 0.19) than the PSD group (0.34 ± 0.16, P < 0.001). This study shows significant differences in subsequent performance in the team leader trained with RCDP and suggests that RCDP may improve retention of pediatric resuscitation skills compared with PSD. Future studies should focus on best applications for RCDP with attention to knowledge and skill decay.

Nontechnical skills (NTS) in medicine are the "cognitive, social, and personal resource skills that complement technical skills contributing to safe and efficient care." We aimed to (1) evaluate the validity and reliability of a 12-element United Kingdom emergency medicine (EM) NTS assessment tool in the context of United States (US) EM practice and (2) identify behaviors unique to US clinical practice. This was a mixed methods study conducted in 2 phases, following Kane's validity framework. The intended use of the NTS tool is to provide formative assessment of US EM physicians (EPs) from a video of simulated clinical encounters. In phase I, a focus group assessed the appropriateness of each aspect of the tool in the context of US EM practice by reviewing and identifying the NTS of an EP in a simulated clinical scenario. In phase II, EPs (N = 208) attending a national EM conference evaluated an EP's behaviors in 1 of 2 video simulations. Reliability in the form of internal consistency was calculated using Cronbach
