This study assessed whether having access to provisions in the American Aca
demy of Pediatrics "medical home" concept was associated with being age-app
ropriately immunized at 3, 12, and 24 months, Cross-sectional data on 495 D
elaware children were collected from June 1994 to June 1995. Immunization s
tatus was determined with the Delaware immunization registry. The medical h
ome was not significantly associated with immunization coverage. This study
confirms that race, insurance status, maternal education, and family incom
es are predictive of having poor immunization outcomes. Simply providing me
dical homes may not be an effective strategy to improve use of preventive s
ervices.
