This article examines the impact of increasing competition among hospitals on access to inpatient services and preexisting differences in access between nonprofit and for-profit facilities. It tests theoretical propositions that suggest that nonprofit and for-profit hospitals will respond in different ways and to differing degrees to changing competitive pressures.
Drawing data from a 1987-88 national survey of psychiatric hospitals, the authors measured access in terms of the availability of different types of services and the provision of uncompensated care. The impact of hospital ownership, competition as well as the interaction of ownership and competition was assessed through a set of regression models, controlling for other characteristics of the hospital markets and local service system.
Nonprofit psychiatric hospitals provide greater access than their for-profit counterparts under conditions of limited competition. Increased competition reduces the ownership-related differences in uncompensated care, but increases the differences for marginally profitable services. The market share of for-profit hospitals had an independent negative effect on access, holding constant the intensity of competition.
The interaction of ownership and competition explains some seemingly inconsistent finding in the literature and points to the complexity of relying on ownership-based policies to protect access in an increasingly competitive health-care system.
本文探讨医院间竞争加剧对住院服务可及性的影响,以及非营利性和营利性机构在可及性方面先前存在的差异。它检验了一些理论命题,这些命题表明非营利性医院和营利性医院对不断变化的竞争压力会以不同方式、不同程度做出反应。
作者从1987 - 1988年全国精神病医院调查中提取数据,从不同类型服务的可获得性和无偿护理的提供情况来衡量可及性。通过一组回归模型评估医院所有权、竞争以及所有权与竞争的相互作用的影响,同时控制医院市场和当地服务系统的其他特征。
在竞争有限的情况下,非营利性精神病医院比营利性同行提供了更大的可及性。竞争加剧减少了无偿护理方面与所有权相关的差异,但增加了微利服务方面的差异。营利性医院的市场份额对可及性有独立的负面影响,竞争强度保持不变。
所有权与竞争的相互作用解释了文献中一些看似不一致的发现,并指出在日益竞争激烈的医疗保健系统中,依靠基于所有权的政策来保护可及性的复杂性。
