To examine the impact of a Wisconsin health care reform enacted in early 2008 on public insurance enrollment and retention.
Administrative data covering the period January 2007 to November 2009.
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.
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.
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.
考察 2008 年初实施的威斯康星州医疗改革对公共保险参保和续保的影响。
涵盖 2007 年 1 月至 2009 年 11 月期间的行政数据。
我们按年龄、收入群体和参保模式计算了未经调整的参保趋势和退出率。使用 Kaplan-Meier 曲线和 Cox 比例风险模型来评估改革对计划退出的影响。
总体参保人数增加了约三分之一，退出率下降了约五分之一。新增参保人员主要来自以前符合收入条件的人群。
威斯康星州实施的资格扩大，加上行政简化以及有针对性的营销和外展工作，成功地使低收入儿童和家庭参保并续保公共保险。
