IntroductionTrauma surgery skills sustainment and maintenance of combat readiness present a major problem for military general surgeons. The Military Health System (MHS) utilizes the knowledge, skills, and abilities (KSA) threshold score of 14,000 as a measure of annual deployment readiness. Only 9% of military surgeons meet this threshold. Most military-civilian partnerships (MCPs) utilize just-in-time training models before deployment rather than clinical experiences in trauma at regular intervals (skills sustainment model). Our aim is to evaluate an established skills sustainment MCP utilizing KSAs and established military metrics.Materials And MethodsThree U.S. Navy active duty general surgeons were embedded into an urban level-1 trauma center taking supervised trauma call at regular intervals prior to deployment. Operative density (procedures/call), KSA scores, trauma resuscitation exposure, and combat casualty care relevant cases (CCC-RCs) were reviewed.ResultsDuring call shifts with a Navy surgeon present an average 16.4 trauma activations occurred; 32.1% were category-1, 27.6% were penetrating, 72.4% were blunt, and 33.8% were admitted to the intensive care unit. Over 24 call shifts of 24 hours in length, 3 surgeons performed 39 operative trauma cases (operative density of 1.625), generating 11,683 total KSA points. Surgeons 1, 2, and 3 generated 5109, 3167, and 3407 KSA points, respectively. The three surgeons produced a total of 11,683 KSA points, yielding an average of 3,894 KSA points/surgeon. In total, 64.1% of operations fulfilled CCC-RC criteria.ConclusionsBased on this initial evaluation, a military surgeon taking two calls/month over 12 months through our regional skills sustainment MCP can generate more than 80% of the KSA points required to meet the MHS KSA threshold for deployment readiness, with the majority being CCC-RCs. Intangible advantages of this model include exposure to multiple trauma resuscitations while possibly eliminating just-in-time training and decreasing pre-deployment requirements.Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2022.
