# Heterogeneity in Military Trauma Casualty Care.

INTRODUCTION: Military combat casualty care is at the forefront of military medical readiness, but there is little data on current proficiency of deployed personnel. A previous study identified a potential performance gap in military trauma teams. This study aims to evaluate a subsequent team to determine if heterogeneity of teams exists and to determine if this level of efficiency persists or can be improved.

MATERIALS AND METHODS: Military trauma teams at the Role 3 hospital in Bagram, Afghanistan, were evaluated over the course of a single deployment between April and October 2018. Trauma teams were directly observed and performance of the ATLS primary trauma survey timed. These results were compared to previously published times from Kandahar and Bagram Role 3 sites from Oct 2016 to Apr 2017.

RESULTS: Time to completion of the primary survey in 2018 was statistically faster than the times reported from the Role 3 sites from Oct 2016 to Apr 2017 (344.75 s vs. 482.8 s, p < 0.05). The greatest improvements of efficiency were in the time periods between assessing the airway and breathing, evaluating the patient's circulation, and completing of the primary survey.

CONCLUSIONS: Trauma teams can vary significantly in their efficiency in evaluating trauma patients. Whether this is clinically significant is currently debatable, but it highlights a possible readiness gap for deploying military personnel and the heterogeneity of military combat casualty care.
