Abstract
BACKGROUND: Multicasualty events present complex medical challenges. This is the first study to investigate the role of nontechnical skills in prehospital multicasualty trauma care. We assessed the feasibility of using the Trauma Nontechnical Skills Scale (T-NOTECHS) instrument, which has not yet been investigated to evaluate these scenarios. METHODS: We conducted an observational study involving military medical teams with Israel Defense Forces Military Trauma Life Support training to assess the T-NOTECHS' utility in predicting prehospital medical team performance during multicasualty event simulations. These teams were selected from a pool of qualified military Advanced Life Support providers. Simulations were conducted in a dedicated facility resembling a field setting, with video recordings to ensure data accuracy. Teams faced a single multicasualty scenario, assessed by two instructors, and were evaluated using a 37-item checklist. The T-NOTECHS scores were analyzed using regression models to predict simulation performance. RESULTS: We included 27 teams for analysis, led by 28% physicians and 72% paramedics. Interrater reliability for simulation performance and T-NOTECHS scores showed good agreement. Overall T-NOTECHS scores were positively correlated with simulation performance scores ( R = 0.546, p < 0.001). Each T-NOTECHS domain correlated with simulation performance. The Communication and Interaction domain explained a unique part of the variance ( β = 0.406, p = 0.047). Assessment and Decision Making had the highest correlation ( R = 0.535, p < 0.001). These domains significantly predicted specific items on the simulation performance checklist. Cooperation and Resource Management showed the least correlation with checklist items. CONCLUSION: This study confirms the T-NOTECHS' reliability in predicting prehospital trauma team performance during multicasualty scenarios. Key nontechnical skills, especially Communication and Interaction, and Assessment and Decision Making, play vital roles. These findings underscore the importance of training in these skills to enhance trauma care in such scenarios, offering valuable insights for medical team preparation. LEVEL OF EVIDENCE: Diagnostic Tests or Criteria; Level III.
