Assessing the Overall Technical Efficiency, Pure Technical Efficiency, and Scale Efficiency of United States Department of Defense Hospitals by Oh D, Lee KH, Choi D

“…The inefficiency of all US Department of Defense hospitals may be due to the lack of pure technical efficiency rather than the suboptimal scale. However, as the efficiency trends in Navy hospitals differ from those in Army and Air Force hospitals, we should be careful in addressing the inefficiency of each type of US Department of Defense hospital.Conclusion: Informed by the findings, this study enhances our understanding of US Department of Defense hospital efficiency and the policy implications, offering practical advice to healthcare policymakers, hospital executives, and managers on managing military hospitals.Keywords: U.S. …”
