Federal funding for children's health insurance may significantly reduce the problem of uninsured children in New York and subsequently improve child outcomes. This study evaluated the effectiveness of two program models in educating parents about available sources of health insurance and in increasing enrollment of uninsured children into Medicaid or Child Health Plus (CHP), New York's insurance program for children of low-income families. One model targeted low-income families applying for or receiving Women, Infants, and Children (WIC) nutritional services. The second model targeted owners/employees of small businesses selling WIC-approved foods and sought to educate them about the availability of Medicaid and CHP and to conduct enrollment at vendor sites. Pre- and post-implementation surveys were conducted to assess knowledge about health insurance, Medicaid, and CHP and to determine baseline enrollment rates. Findings indicated that WIC sites were ideal enrollment assistance sites. Awareness grew from 46 to 65 percent at enrollment-assistance sites, whereas comparison sites saw an increase from 52 to only 60 percent. Enrollment in CHP increased from 12 to 16 percent at intervention sites, compared to an increase from 8 to only 10 percent at comparison sites. Medicaid enrollment increased slightly at intervention sites and declined at the comparison sites. Small businesses participating in the WIC program were effective outreach vehicles but not efficient venues for enrollment. Facilitators could enroll approximately 1,000 children yearly at a cost of $35 per application. It was concluded that new efforts are needed to reach families within their own communities and to facilitate their enrollment in Medicaid and CHP. (KB)
