162 The New Military Neurosurgeon Readiness Metric to Assess Surgical Readiness and Deployability

Abstract

INTRODUCTION: The US Military Health System includes military treatment facilities (MTFs) and deployable medical providers that have a dual mission to provide a “medically ready force and a ready medical force”. During wartime, the surge in casualties provides abundant surgical case volume to train and sustain a ready medical force. In contrast, peacetime poses a major challenge to military provider readiness, where lessons learned are quickly forgotten and advancements in trauma and combat surgical care decelerate; a phenomenon coined the “Walker dip”. As such, the Defense Health Agency in 2019 mandated critical wartime specialties develop specialty-specific readiness metrics to measure and maintain skills and competencies, named Knowledge, Skills, and Abilities (KSA). The neurosurgery KSA metric was released in early 2023. METHODS: Case counts and associated KSA values were obtained for active duty (AD) military neurosurgeons and neurosurgery-capable MTFs over the last 12 months. RESULTS: The neurosurgery KSA metric is a point-based system that assigns case valuations based on five categories: cranial (70 points), spine (45), peripheral (15), endovascular (5) and minor (5). The threshold KSA value per provider is set at 8000 points annually, or 667 monthly. Threshold was selected as the average between the KSA of a typical level II trauma center annual case volume and initial ABNS certification caseload requirements. Of 51 AD neurosurgeons from 16 MTFs over a 12-month period, only three providers have monthly KSA values above threshold; all of which have duty assignments at civilian institutions. CONCLUSIONS: Less than 10% of AD military neurosurgeons are meeting readiness thresholds per the KSA metric. However, no internal/external validation has been performed. Future validation studies will be pivotal in determining metric accuracy and guide adjustments to ensure a medically capable military force.
