INTRODUCTION Decay of military surgeons' critical wartime skills is a persistent and growing concern among leaders in the military health system (MHS). The Knowledge, Skills and Abilities (KSA) Clinical Readiness Program was developed to quantify the readiness of clinicians in the MHS; however, the utility of the data is questionable due to a lack of focus on the operative expeditionary skillset in the original methodology. A revised methodology emphasizing the most relevant to expeditionary orthopedic surgery procedures is described. MATERIALS AND METHODS All Current Procedural Terminology (CPT) codes included in the original KSA methodology were reviewed and, if appropriate, removed, or reassigned to more suitable categories. Category scores were weighted to better align with the most performed procedures in the deployed environment. All surgical cases and procedures performed from 2017-2019 in military treatment facilities by orthopedic surgeons were recorded in total and by MHS market. Cases were recorded for all military orthopedic surgeons who performed at least one KSA credit procedure during the study period. The 10 MHS markets with the greatest number of procedures were included in the analysis. The change in creditable KSA procedure codes and procedures performed from the original to revised methodology was determined for each KSA category and MHS market. RESULTS Overall, 403 CPT codes were recategorized and 79 were deleted from the original KSA methodology. The deletions represented less than 4% of the original creditable CPT codes, with most being supply or injection codes. Three of the five most common expeditionary KSA categories increased in the number of creditable procedure codes. The impact of the revision on the MHS markets was mixed, but the overall volume of credited procedures decreased. The weighted scoring did not disproportionately affect the analyzed markets. CONCLUSIONS The revised methodology is better aligned with the most common procedures in the most recent large-scale military engagements. The improved applicability of the KSA scoring to necessary CWS will allow military medical leaders to better determine the readiness opportunities available in the MHS.
