General hospitals are consistently under pressure to control cost and improve quality. In addition to mounting payers' demands, hospitals operate under evolving market conditions that might threaten their survival. While hospitals traditionally were concerned mainly with competition from other hospitals, today's reimbursement schemes and entrepreneurial activities encouraged the proliferation of outpatient facilities such as ambulatory surgery centers (ASCs) that can jeopardize hospitals' survival.
The purpose of this article was to examine the relationship between ASCs and general hospitals. More specifically, we apply the niche overlap theory to study the impact that competition between ASCs and general hospitals has on the survival chances of both of these organizational populations.
Our analysis examined interpopulation competition in models of organizational mortality and market demand. We utilized Cox proportional hazard models to evaluate the impact of competition from each on ASC and hospital exit while controlling for market factors. We relied on two data sets collected and developed by Florida's Agency for Health Care Administration: outpatient facility licensure data and inpatient and outpatient surgical procedure data.
Although ASCs do tend to exit markets in which there are high levels of ASC competition, we found no evidence to suggest that ASC exit rates are affected by hospital density. On the other hand, hospitals not only tend to exit markets with high levels of hospital competition but also experience high exit rates in markets with high ASC density.
The implications from our study differ for ASCs and hospitals. When making decisions about market entry, ASCs should choose their markets according to the following: demand for outpatient surgery, number of physicians who would practice in the surgery center, and the number of surgery centers that already exist in the market. Hospitals, on the other hand, should account for competition from ASCs while making market-entry decisions and while developing their strategic plans.
综合医院一直面临着控制成本和提高质量的压力。除了不断增加的支付者的需求,医院还在不断变化的市场环境下运营,这可能威胁到它们的生存。虽然医院传统上主要关注来自其他医院的竞争,但今天的报销计划和创业活动鼓励了门诊设施(如门诊手术中心)的扩散,这可能危及医院的生存。
本文旨在研究 ASC 与综合医院之间的关系。更具体地说,我们应用生态位重叠理论来研究 ASC 和综合医院之间的竞争对这两种组织群体的生存机会的影响。
我们的分析在组织死亡率和市场需求模型中检验了种群间的竞争。我们使用 Cox 比例风险模型来评估来自 ASC 和医院的竞争对 ASC 和医院退出的影响,同时控制市场因素。我们依赖佛罗里达州卫生保健管理局收集和开发的两个数据集:门诊设施许可数据和住院和门诊手术程序数据。
尽管 ASC 确实倾向于退出竞争激烈的市场,但我们没有证据表明 ASC 的退出率受到医院密度的影响。另一方面,医院不仅倾向于退出竞争激烈的市场,而且在 ASC 密度高的市场中退出率也很高。
我们的研究结果对 ASC 和医院的意义不同。在做出市场进入决策时,ASC 应该根据以下因素选择其市场:门诊手术的需求、愿意在手术中心执业的医生数量以及市场上已有的手术中心数量。另一方面,医院在做出市场进入决策和制定战略计划时,应该考虑到来自 ASC 的竞争。
