Policymakers and researchers are concerned that changes in the healthcare market have stressed and weakened the safety net nationwide.
The objectives of this study were to investigate variations in the safety net across communities and over time and to explore the effect of market changes on the safety net.
We examined the safety net in all large urban communities from 1993 to 1998. Data from a variety of sources measure uncompensated hospital care, local government spending for health, admissions to safety net hospitals, visits to outpatient departments of safety net hospitals, visits to community health centers, and demographic and market characteristics of the communities. Descriptive analyses examine trends and community variations. Multivariate methods are used to estimate the effect of market structure and of economic factors on the safety net.
The safety net did not erode in urban areas over the study period. There was substantial variation across communities, but the disparity did not increase over time. HMO penetration and hospital competition are not significantly related to variations in the safety net, although demographic and economic factors are.
Local financing capacity is a factor in variations across communities in the safety net. The economic downturn and pressures on state budgets could lead to future problems.
政策制定者和研究人员担心医疗保健市场的变化给全国范围内的安全网带来压力并使其遭到削弱。
本研究的目的是调查不同社区以及不同时期安全网的差异,并探究市场变化对安全网的影响。
我们研究了1993年至1998年期间所有大型城市社区的安全网情况。来自各种来源的数据衡量了未补偿的医院护理、地方政府的卫生支出、安全网医院的入院人数、安全网医院门诊部的就诊人次、社区卫生中心的就诊人次以及社区的人口和市场特征。描述性分析考察了趋势和社区差异。多变量方法用于估计市场结构和经济因素对安全网的影响。
在研究期间,城市地区的安全网并未受到侵蚀。不同社区之间存在很大差异,但这种差距并未随时间增加。健康维护组织(HMO)的渗透率和医院竞争与安全网的差异没有显著关系,尽管人口和经济因素与之有关。
地方融资能力是不同社区安全网存在差异的一个因素。经济衰退和州预算压力可能导致未来出现问题。
