Introduction: The objective of this study was to review the empirical evidence on Patient-Centered Medical Home (PCMH) impact on health disparities in adults.

Methods: We searched PubMed, Scopus, and Google Scholar to identify studies on PCMH/health homes and health disparities published in English between January 1, 2009 and December 31, 2014. Articles met inclusion criteria if they investigated at least one component of PCMH or health homes in vulnerable populations, defined by PROGRESS-PLUS criteria, and reported differences in one of five clinical quality measures.

Results: 964 articles were identified through database searching and subsequent snowballing. 60 articles underwent full text screening. Further review eliminated 56 studies. In the final 4 studies, PCMH interventions showed small improvements in health disparities.

Discussion: The PCMH has been suggested as a model for improving health disparities. Given rapid implementation in underserved settings, stakeholders should better understand the impact of the PCMH on health disparities.
