Using two different practice-reported patient-centered medical home (PCMH) assessments, this study estimates the association between medical homeness and health care utilization by children with Medicaid. Multilevel logistic regression models are estimated on Medicaid claims data from 32 practices in Illinois that used the National Committee on Quality Assurance PCMH assessment and 32 practices in North Carolina and South Carolina that completed the Medical Home Index. Medical homeness was not associated with receipt of age-appropriate well-child visits in either sample. Children in practices in Illinois with the highest tertile PCMH scores were less likely to have an avoidable emergency department visit than children in practices with the lowest tertile scores.
