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 ≤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.
