Napa Immunization Study: Immunization Rates for Children with Publicly Funded Insurance Compared with those with Private Health Insurance in a Suburban Medical Office.
BACKGROUND
Healthy People 2020 set a goal to increase the proportion of children who receive the recommended doses of Diphtheria Tetanus and Pertussis, polio, measles mumps and rubella, Haemophilus influenzae type b, hepatitis B, varicella and pneumococcal conjugate vaccines to 80% from the 2009 baseline rate of 69%. The purpose of this study is to compare the recommended immunization rates for low-income children insured through publicly funded health insurance (PFI) to the rates for children with private health insurance (PHI) in a suburban medical office.


METHODS
The immunization rates and health access measures of 109 children ages 24 to 48 months who had PFI were compared with 300 children of the same age with PHI in the same medical practice.


RESULTS
Overall immunization rates for the study population were very high and exceeded the Healthy People 2020 goals for full immunization. Children with PFI had lower rates of immunization and fluoride prescriptions; however the differences were only significant in the cohort of children age two years. By three years of age, the immunization rates and the fluoride prescription rates were similar. There were no significant differences in health outcomes for Spanish-speaking compared with English-speaking children.


CONCLUSIONS
Barriers to successful immunization practices and strategies to overcome those barriers are discussed.


CONCLUSIONS
The successful immunization practices and secondary outcomes in this study are a reflection of the integrated care model in this practice that facilitates comprehensive, coordinated, and accessible care for patients and allows physicians and support staff to practice culturally sensitive and compassionate care-the definition of a medical home.
