Maryland multipayor patient-centered medical home program: a 4-year quasiexperimental evaluation of quality, utilization, patient satisfaction, and provider perceptions. Medical care. 2018 Apr;56(4):308.
The study evaluates the impact of the Maryland Multipayor Patient centered Medical Home Program (MMPP), launched in 2011. After 3 years, PCMH patients were
9% less likely to experience an ED visit, 34% more likely to experience an inpatient stay, and were 51% more likely to experience a 30‐day readmission in comparison to non‐PCMH patients. Patients with asthma, CHF or diabetes were 19% less likely to experience an ED visit, and were 32% less likely to experience an inpatient stay.
