Objective
To assess whether a model of care with augmented services within an existing medical home could improve immunization rates for Children with Special Health Care Needs (CSHCN) and to evaluate the influence of family and practice characteristics on these children’s immunization rates.
Method
Participants were six general pediatric practices, CSHCN, and their families. Enhancements were added to the medical home for CSHCN, including additional nurse practitioner time. A prospective survey and chart review of volunteer families was made in 1998 repeating the chart review in 2000.
Results
The immunization rates of CSHCN in the practices before the intervention was 83.4% for DTaP, polio and MMR and 80% if HIB and HepB were added. The intervention did not improve these already high rates. In regression models, children with late onset disorders were more likely NOT to be up-to-date (UTD) by 2 years of age (OR 3.29). CSHCN cared for by non-birth parents and CSHCN whose family incomes were greater than $40,000 per year were also more likely NOT to be UTD (OR 3.81, 2.75 respectively) as were patients of providers not satisfied with any aspect of serving patients (OR 3.29).
Conclusions
In these practices already committed to a medical home model of care for CSHCN, immunization rates were at or above state and national averages before any intervention took place. Some groups of patients among these CSHCN were more likely to be delayed with immunizations, including those with late onset disorders and those with high family incomes.
