This research examines the relationship of competition among nursing homes and the likelihood of their closure or change in ownership. The study uses nationally representative data from the 1992-1998 Online Survey, Certification, and Reporting system, and is supplemented with several other primary and secondary data sources. It is hypothesized that facilities located in more competitive environments will be more likely to close. Multinomial logistic regression analyses are employed to examine this hypothesis in a model containing organizational and aggregate resident characteristics, and market factors. The Herfindahl index is used as a measure of competition. The descriptive analysis shows that 621 nursing homes closed and 6,471 changed ownership from 1992 to 1998. The incidence rate of closures was .7% of facilities per year. The multivariate analysis shows that facilities located in more competitive environments were significantly more likely to close.
本研究考察了养老院之间的竞争关系以及它们关闭或所有权变更的可能性。该研究使用了1992 - 1998年在线调查、认证和报告系统中的全国代表性数据，并辅以其他几个主要和次要数据源。研究假设是，位于竞争更激烈环境中的机构更有可能关闭。采用多项逻辑回归分析在一个包含机构和总体居民特征以及市场因素的模型中检验这一假设。赫芬达尔指数被用作竞争的衡量指标。描述性分析表明，1992年至1998年期间有621家养老院关闭，6471家所有权发生变更。关闭的发生率为每年设施总数的0.7%。多变量分析表明，位于竞争更激烈环境中的机构关闭的可能性显著更高。
