IntroductionMedications play a critical role supporting the health of military service members. Little is known about the broad use of medications prescribed to this population. Active duty service members (ADSMs), while often younger and having fewer diagnosed comorbid conditions, face unique health challenges that benefit from pharmacotherapy. Understanding prescribing patterns is instrumental to illuminate potential areas for research and to guide education so that military health care professionals can maintain competency, improve outcomes, and support medical readiness. This study aimed to characterize commonly dispensed medications among ADSMs and to compare these prescriptions with those of the general population.Materials And MethodsA retrospective, cross-sectional analysis using data extracted contained in the Military Health System Information Platform focused on ADSMs who consulted with a clinical pharmacist during the 2019 fiscal year. Descriptive statistics were used to summarize patient and prescription data. The 100 most frequently prescribed medications and 20 most frequently prescribed therapeutic classes were identified. Analyses were performed using Statistical Analysis System (SAS) software, and a non-metric multidimensional scaling plot was generated in R to illustrate the relationships between the 20 most frequently used therapeutic classes and the branches of service.ResultsThe study analyzed 719,788 prescriptions for 30,012 service members, revealing a high prescription rate for pain, inflammation, and psychiatric condition treatments. Antidepressants and nonsteroidal anti-inflammatory drugs were among the most commonly prescribed across all military branches. Some medication uses varied, which may indicate distinct needs within different service branches.ConclusionsUnderstanding medication patterns among ADSMs may be able to help health care professionals proactively address pharmacological challenges and optimize pharmaceutical use in this unique population. This knowledge can also aid in the development of training modules focused on medication side effects, interactions, counseling, and implications on military deployment for the most commonly used medications. Future examination into prescribing cascades and medication use related to proton-pump inhibitors, docusate, benzonatate, and muscle relaxants may identify opportunities to provide better care or lower cost.© The Association of Military Surgeons of the United States 2024.
