The Military Health System (MHS) includes over 300 Medical Centers, Hospitals and Clinics located worldwide on Army, Navy, Air Force and Marine Corps installations. In 2011, the MHS began transforming its over 440 primary care practices within MTFs into the PCMH model of care and adopted NCQA PCMH standards to establish consistent Tri-Service operating principles, which the Uniformed Services used to develop MTF operating guidance. As a result, the MHS has been able to standardize business and clinical operational workflow, appointing/scheduling templates, staffing models, performance measures, goals and a capitated revised financing model.
