As safety net providers, public hospitals operate in more challenging environments than private hospitals. Such environments put public hospitals at greater risk of financial distress, which may result in privatization and deterioration of the safety net.
The purpose of this study was to investigate whether financial distress is associated with privatization among public hospitals.
METHODOLOGY/APPROACH: We used panel data merged from the American Hospital Association Annual Survey, Medicare Cost Reports, Area Resource File, and Local Area Unemployment Statistics. Our study population consisted of all U.S. nonfederal acute care public hospitals in 1997 tracked through 2009, resulting in 6,426 hospital-year observations. The dependent variable "privatization" was defined as conversion from public status to either private not-for-profit or private for-profit status. The main independent variable, "financial distress," was based on the Altman Z-score methodology. Control variables included market and organizational factors. Two random-effects logistic regression models with state and year fixed-effects were constructed. The independent and control variables were lagged by 1 year and 2 years for Models 1 and 2, respectively.
Public hospitals in financial distress had greater odds of being privatized than public hospitals not in financial distress: (OR = 4.53, p < .001) for Model 1 and (OR = 3.05, p = .001) for Model 2.
Privatization eases access to resources and may provide financial relief to government entities from the burden of continuously funding a hospital operating at a loss, which in turn may help keep the hospital open and preserve access to care for the community. Privatizing a financially distressed public hospital may be a better strategic alternative than closure. The Altman Z-score could be used as a managerial tool to monitor hospitals' financial condition and take corrective actions.
作为安全网提供者,公立医院比私立医院在更具挑战性的环境中运营。此类环境使公立医院面临更大的财务困境风险,这可能导致私有化以及安全网的恶化。
本研究的目的是调查公立医院的财务困境是否与私有化相关。
方法/途径:我们使用了合并自美国医院协会年度调查、医疗保险成本报告、区域资源文件和地方失业率统计数据的面板数据。我们的研究对象包括1997年至2009年期间追踪的所有美国非联邦急症护理公立医院,共产生6426个医院年度观察值。因变量“私有化”定义为从公立状态转变为私立非营利或私立营利状态。主要自变量“财务困境”基于奥特曼Z计分法。控制变量包括市场和组织因素。构建了两个具有州和年份固定效应的随机效应逻辑回归模型。模型1和模型2的自变量和控制变量分别滞后1年和2年。
处于财务困境的公立医院比未处于财务困境的公立医院被私有化的几率更高:模型1为(比值比=4.53,p<.001),模型2为(比值比=3.05,p=.001)。
私有化便于获取资源,可能使政府实体从持续资助亏损运营医院的负担中得到财务缓解,这反过来可能有助于维持医院运营并保留社区的医疗服务可及性。将处于财务困境的公立医院私有化可能是比关闭更好的战略选择。奥特曼Z计分法可作为一种管理工具,用于监测医院的财务状况并采取纠正措施。
