Quality and equity of primary care with patient-centered medical homes: results from a national survey.

BACKGROUND: The patient-centered medical home (PCMH) model has gained support, but the impact of this model on the quality and equity of care merits further evaluation. OBJECTIVE: To determine if PCMHs are associated with improved quality and equity in pediatric primary care. RESEARCH DESIGN: Using the 2007/2008 National Survey of Children's Health, a nationally representative survey of parents/guardians of children (age, 0-17 y), we evaluated the association of PCMHs with 10 quality-of-care measures using multivariable regression models, adjusting for demographic and socioeconomic covariates. For quality indicators that were significantly associated with medical homes, we determined if this association differed by race/ethnicity. RESULTS: Compared with children without medical homes, those with medical homes had significantly better adjusted rates for 6 of 10 quality measures (all P≤0.02), such as obtaining a developmental history [adjusted rates % (SE): 41.7 (1.3) vs. 52.0 (1.1), P
