Objectives:
To examine the impact of a Wisconsin health care reform enacted in early 2008 on public insurance enrollment and retention.
Data Sources:
Administrative data covering the period January 2007 to November 2009.
Study Design:
We calculate unadjusted enrollment trends and exit rates stratified by age, income group, and enrollment mode. Kaplan-Meier curves and Cox proportional hazards models are estimated to assess the impact of the reform on program exits.
Principal Findings:
Overall enrollment increased by approximately one-third and exit rates decreased by approximately one-fifth. The majority of new enrollment came from the previously income eligible.
Conclusions:
Wisconsin's enactment of eligibility expansions coupled with administrative simplification and targeted marketing and outreach efforts were successful in enrolling and retaining low-income children and families in public coverage.
