  1. Impact of a large-scale immunization initiative in the Special Supplemental Nutrition Program for Women, infants, and Children (WIC).

    Article - En anglais

    Context. - Inner-city immunization rates have lagged behind those in other areas of the country.

    Objective

    - To evaluate the impact of an initiative linking immunization with dis tribution of food vouchers in the inner city.

    Design

    - Retrospective analysis of immunization data gathered in 1996 an 1997.

    Setting

    - Nineteen Special Supplemental Nutrition Program for Women, In fants, and Children (WIC) sites serving 30% of the Chicago, III, birth cohort.

    Participants

    - A total of 16 581 children 24 months old or younger.

    Interventions

    - Voucher incentives (varying frequency of food voucher issu ance based on immunization status) and assessment of immunization status and referral to immunization provider.

    Main Outcome Measures

    - Age-appropriate immunization rates and WIC en rollment rates.

    Results

    - During the 15-month period of evaluation, immunization rates in creased from 56% to 89% at sites performing voucher incentives.

    The proportior of children needing voucher incentives declined from 51% to 12%. Sites perform ing assessment and referral, but not providing voucher incentives, showed no evidence of improvement in immunization coverage.

    No difference was observed ir enrollment rates between sites performing voucher incentives and those that did not.

    Conclusion

    - Applied in a large-scale, programmatic fashion, voucher incentives in WIC can rapidly increase and sustain high childhood immunization rates ir an inner-city population.
