Introduction: Medicaid agencies have been promoting the patient-centered medical home (PCMH) model. Most care-givers choose physician practices for their children, and we hypothesized that those following healthier childrearing practices are more likely to seek care in a PCMH. Method: We selected children with public insurance plans (n = 20,801) from the 2011-2012 National Survey of Children's Health. We used generalized ordinal logistic regression with state fixed effects to assess the association between home environments and children's use of PCMHs. Results: Children living in the healthiest homes were 1.33 times (p = .001) more likely to receive care from the highest level of PCMH. In states with early PCMH implementation, the odds increased to 2.11 times (p = .001). Discussion: Our results show a significant, sizeable relationship between healthier home environments and the use of PCMH by children from low-income families. They provide implications for assessing the effect of PCMH use on health outcomes and use patterns.
