Crowd-out in the State Children's Health Insurance Program (SCHIP): incidence, enrollee characteristics and experiences, and potential impact on New York's SCHIP.

Department of Pediatrics, School of Nursing, University of Rochester School of Medicine and Dentistry, 601 Elmwood Avenue, Box 777, Rochester, NY, USA.

BACKGROUND: The extent to which the State Children's Health Insurance Program (SCHIP) crowds our private insurance is poorly understood. OBJECTIVE: To assess the incidence of crowd-out and enrollee characteristics associated with crowd-out. DATA: Parent telephone survey for 2,644 children after enrollment in NY SCHIP. MEASURES AND ANALYSES: Crowd-out is measured based on enrollee reports of coverage (and loss of coverage) before SCHIP. Multivariate logistic regression is used to relate crowd-out to enrollee characteristics. PRINCIPAL FINDINGS: Only 7.1 percent of SCHIP enrollees dropped private coverage < or =6 months before SCHIP, suggesting relatively modest crowd-out. Crowd-out was associated with some enrollee traits including income, but not with health status. IMPLICATIONS: Most movement from private to public insurance in NY was not crowd-out. Under current program structure in NY, crowd-out concerns should not dampen enthusiasm for SCHIP.
