Patient Experience with the Patient-Centered Medical Home in Michigan's Statewide Multi-Payer Demonstration: A Cross-Sectional Study.

BACKGROUND: The literature on patient-centered medical homes (PCMHs) and patient experience is somewhat mixed. Government and private payers are promoting multi-payer PCMH initiatives to align requirements and resources and to enhance practice transformation outcomes. To this end, the multipayer Michigan Primary Care Transformation (MiPCT) demonstration project was carried out.

OBJECTIVE: To examine whether the PCMH is associated with a better patient experience, and whether a mature, multi-payer PCMH demonstration is associated with even further improvement in the patient experience.

DESIGN: This is a cross-sectional comparison of adults attributed to MiPCT PCMH, non-participating PCMH, and non-PCMH practices, statistically controlling for potential confounders, and conducted among both general and high-risk patient samples.

PARTICIPANTS: Responses came from 3893 patients in the general population and 4605 in the high-risk population (response rates of 31.8% and 34.1%, respectively).

MAIN MEASURES: The Clinician and Group Consumer Assessment of Healthcare Providers and Systems survey, with PCMH supplemental questions, was administered in January and February 2015.

KEY RESULTS: MiPCT general and high-risk patients reported a significantly better experience than non-PCMH patients in most domains. Adjusted mean differences were as follows: access (0.35**, 0.36***), communication (0.19*, 0.18*), and coordination (0.33**, 0.35***), respectively (on a 10-point scale, with significance indicated by: *= p<0.05, **= p<0.01, and ***= p<0.001). Adjusted mean differences in overall provider ratings were not significant. Global odds ratios were significant for the domains of self-management support (1.38**, 1.41***) and comprehensiveness (1.67***, 1.61***). Non-participating PCMH ratings fell between MiPCT and non-PCMH across all domains and populations, sometimes attaining statistical significance.

CONCLUSIONS: PCMH practices have more positive patient experiences across domains characteristic of advanced primary care. A mature multi-payer model has the strongest, most consistent association with a better patient experience, pointing to the need to provide consistent expectations, resources, and time for practice transformation. Our results held for a general population and a high-risk population which has much more contact with the healthcare system.
