Background: The Pediatric Immunization Program (PIP) was initiated in 1993 to achieve on-time immunization in the first 2 years of life using a “reminder-recall on foot” strategy. We canvassed public housing, assessed children's immunization status, and referred infants to their medical home when delayed immunization and well child care receipt was documented. This initial approach was successful but labor-intensive. We discovered that the hepatitis B vaccine administered at birth was a positive predictor of on-time compliance in children <35 months of age. We therefore modified our approach and provided an immunization education intervention in the hospital at birth followed by reminder-recall, naming this ongoing intervention “BIRTH PIP.” Setting and Population: University of Chicago Medical Center, south side of Chicago, African-American

Project: We conducted 3 studies (BIRTH PIP 1, 2, and 3), each enrolling 200 newborns. BIRTH PIP 1 and BIRTH PIP 2 lost more than half of enrollees due to setting too narrow a follow-up catchment area and lost contact with many enrollees. Nevertheless, >90% of remaining enrollees were up-to-date. BIRTH PIP 3 followed children anywhere in Chicago and has retained 92% of enrollees with 98% up-to-date.

Results/Lessons Learned: In BIRTH PIP 3, the on-time immunization rate is still >90%. Cost-benefit analyses revealed the less reminding a parent-child unit needed to be compliant with scheduled visits, the less expensive the BIRTH PIP intervention. In conclusion, BIRTH PIP is effective in improving on-time immunization compliance among underserved inner-city children and deserves to be tried on a larger scale.

Learning Objectives:
By the end of the presentation, participants will be able to: 1) Describe how the Pediatric Immunization Program at the University of Chicago Medical Center ("Birth PIP") improves on-time immunization compliance. 2) Describe how the Birth PIP model may be tailored to local community needs.
