Colorado's Child Health Plan Plus (CHP+) is a non-Medicaid state child health plan that began enrollment in April 1998. Families are disenrolled 12 months after enrollment if they fail to re-enroll.


To assess insurance coverage before and 1 year after initial enrollment in CHP+; reasons for disenrollment; and factors associated with re-enrollment.


We interviewed 480 randomly selected families 2 months after initial enrollment into CHP+ (September 1999 through January 2000) and 1 year later.


Prior to CHP+, 38% of families had Medicaid (MK), 35% were privately insured (PI), 6% were uninsured (UI), and 20% had other/unknown insurance. After the 12 months, 34% were re-enrolled, 16% got other insurance (6% MK, 10% PI/other), 4% had children older than 18 years, and 46% were UI (9% had intentionally and 37% had unintentionally disenrolled from CHP+). All unintentionally disenrolled families were planning to re-enroll and 90% still appeared eligible. In multivariate analysis, having a primary care provider prior to enrollment was associated with re-enrollment (odds ratio [OR] 1.7, 95% confidence interval [CI] 1.1 to 2.6), but having problems with the application process impeded re-enrollment (OR 0.7, 95% CI 0.6 to 0.9).


Only about a third of families eligible for State Children's Health Insurance Program successfully re-enrolled before their termination date. Institution of a passive renewal process would decrease unnecessary disenrollment in eligible families.
