Medical Home Characteristics and Quality of Diabetes Care in Safety Net Clinics.

We examined associations between patient-centered medical home (PCMH) characteristics and quality of diabetes care in 15 safety net clinics in five states. Surveys among clinic directors assessed PCMH characteristics using the Safety Net Medical Home Scale. Chart audits among 864 patients assessed diabetes process and outcome measures. We modeled the odds of the patient receiving performance measures as a function of total PCMH score and of PCMH subscales and covariates. PCMH characteristics had mixed, inconsistent associations with the quality of diabetes care. The PCMH model may require refinement in design and implementation to improve diabetes care among vulnerable populations.
