Effect of the Vaccines for Children program on physician referral of children to public vaccine clinics: a pre-post comparison.

Objective: Started in late 1994, the Vaccines for Children (VFC) program is a major entitlement program that provides states with free vaccines for disadvantaged children. Some evaluation studies have been conducted, but they do not include individually matched pre-post comparisons of physician responses. This project studied the effect of the VFC on the physician likelihood of referring children to public vaccine clinics for immunizations.

Methods: In 1999, trained personnel conducted a survey of a cohort of physicians who previously participated in surveys on barriers to childhood vaccination conducted before VFC implementation. Responses were matched, and pre- versus post-VFC comparisons were made. Methods: Minnesota and Pennsylvania primary care physicians selected by stratified random sampling and initially studied in 1990 to 1991 and 1993, respectively. Methods: Likelihood of referral of a child to a public vaccine clinic.

Results: On a scale of 0 to 10, physician likelihood of referring an uninsured child decreased by a mean of 1.9 (95% confidence interval: 1.2-2.5) from pre- to post-VFC. Two fifths (45%) of physicians reported that the VFC decreased the number of referrals from their practice to public vaccine clinics and 50% gave intermediate responses. Among physicians who participate in VFC, only 9% were likely to refer a Medicaid-insured child in contrast to 44% of those not participating.

Conclusions: Physicians' reported referral and likelihood of referring Medicaid-insured and uninsured children has decreased because of VFC in Minnesota and Pennsylvania.vaccination/economics, vaccination/legislation and jurisprudence, immunization programs/economics, immunization programs/utilization, vaccines/economics, Medicaid/economics, national health programs United States, child health services.
