Insurance expansions and service delivery system expansions are alternative policy instruments used to try to improve birth outcomes for low-income women.
The objective of this research is to investigate the effect of expansions of public insurance on access and birth outcomes for pregnant women and the role of different delivery systems in these outcomes.
The experience in Florida during the years 1989-1994 is studied. Data are from linked birth certificates, hospital discharge data, Medicaid eligibility and claims files, and county health department records. Use of prenatal care and birthweight for low-income women is compared under different financing for prenatal care and for those using different delivery systems. Several approaches to control for self-selection are adopted, and similar results are obtained with each.
Women enrolled in Medicaid have more prenatal care visits than the uninsured. Outcomes for those on Medicaid and the uninsured are significantly better if they receive care in the public health system than if they receive care in the private system-including private offices, clinics, and HMOs. Over time, the gap in outcomes between those in the public system and those receiving prenatal care from private physicians has diminished.
Public insurance improves access to services, but the delivery system is a key factor in improving outcomes.
保险覆盖范围的扩大和服务提供体系的扩展是旨在改善低收入女性生育结局的替代性政策手段。
本研究的目的是调查公共保险覆盖范围扩大对孕妇获得医疗服务及生育结局的影响,以及不同服务提供体系在这些结局中所起的作用。
研究了1989年至1994年佛罗里达州的情况。数据来源于关联的出生证明、医院出院数据、医疗补助资格及理赔档案,以及县卫生部门记录。比较了低收入女性在不同产前护理筹资方式下以及使用不同服务提供体系时的产前护理利用情况和出生体重。采用了几种控制自我选择的方法,每种方法都得到了相似的结果。
参加医疗补助的女性比未参保女性接受的产前检查次数更多。对于参加医疗补助的女性和未参保女性而言,如果她们在公共卫生系统接受护理,其结局要明显好于在私人系统(包括私人诊所、门诊部和健康维护组织)接受护理的情况。随着时间的推移,公共系统中的女性与接受私人医生产前护理的女性之间的结局差距有所缩小。
公共保险改善了服务可及性,但服务提供体系是改善结局的关键因素。
