The Balanced Budget Act of 1997 authorizes $20 billion for states to expand health insurance coverage among uninsured low-income children. This study identifies lessons learned from the Medicaid Extension Demonstration, which was authorized by Congress to experiment with innovative approaches to providing health care coverage for low-income children. The three programs compare and contrast a variety of features that may enhance or detract from access, including a traditional Medicaid expansion, a private indemnity model, and a comprehensive managed care delivery system.
Two waves of telephone surveys were conducted with a sample of parents of children participating in the Medicaid Extension Demonstration, and a comparison group of parents of children who were eligible but not participating. Descriptive and multivariate analyses were conducted to determine the impact of the demonstration on access to care.
Compared with those who were uninsured, children in the managed care program were more likely to have a medical home and a physician visit and were less likely to have an emergency room visit, and had lower levels of unmet need. Outcomes across the other two demonstration programs were less favorable.
This study suggests that simply providing a Medicaid card or private indemnity insurance card is not enough to ensure access to care. Future initiatives also need to consider the structure of the delivery system, especially the availability of a medical home (with adequate after-hours care), as well as the impact of discontinuous insurance coverage on access to and continuity of care.
1997年的《平衡预算法案》授权拨款200亿美元给各州,用于扩大未参保低收入儿童的医疗保险覆盖范围。本研究确定了从医疗补助扩展示范项目中吸取的经验教训,该项目经国会授权,旨在试验为低收入儿童提供医疗保健覆盖的创新方法。这三个项目比较并对比了各种可能增强或减少医疗服务可及性的特征,包括传统的医疗补助扩展、私人赔偿模式和综合管理式医疗服务提供系统。
对参与医疗补助扩展示范项目的儿童的家长样本以及符合条件但未参与项目的儿童的家长对照组进行了两轮电话调查。进行了描述性和多变量分析,以确定该示范项目对医疗服务可及性的影响。
与未参保儿童相比,参加管理式医疗项目的儿童更有可能拥有医疗之家并看医生,更不太可能去急诊室就诊,未满足需求的水平也更低。其他两个示范项目的结果则不太理想。
本研究表明,仅仅提供一张医疗补助卡或私人赔偿保险卡不足以确保获得医疗服务。未来的举措还需要考虑医疗服务提供系统的结构,特别是医疗之家(提供充足的非工作时间护理)的可及性,以及间断的保险覆盖对医疗服务可及性和连续性的影响。
