Maeng DD, Khan N, Tomcavage J, Graf TR, Davis DE, Steele GD. Reduced acute inpatient care was largest savings component of Geisinger Health System’s patient-centered medical home. Health Affairs. 2015 Apr 1;34(4):636-44.
The study estimated cost savings associated with Geisinger Health System’s patient-centered medical home clinics by examining longitudinal clinic-level claims data from elderly Medicare patients attending the clinics over a ninety-month period (2006 through the first half of 2013). The results of this study suggest that patient-centered medical homes can lead to sustainable, long-term improvements in patient health outcomes and the cost of care.
