Currently, the Centers for Medicare and Medicaid Services report on 15 Quality Measures (QMs) on the Nursing Home Compare (NHC) website. It is assumed that nursing homes are able to make improvements on these QMs, and in doing so they will attract more residents. In this investigation, we examine changes in QM scores, and whether competition and/or excess demand have influenced these change scores over a period of 1 year.
Data come from NHC and the On-line Survey Certification And Recording (OSCAR) system. QM change scores are calculated using values from January 2003 to January 2004. A series of regression analyses are used to examine the association of competition and excess demand on QM scores.
Eight QMs show an average decrease in scores (ie, better quality) and six QMs show an average increase in scores (ie, worse quality). However, for 13 of the 14 QMs these average changes averaged less than 1%. The regression analyses show an association between higher competition and improving QM scores and an association between lower occupancy and improving QM scores.
As would be predicted based on the market-driven mechanism underlying quality improvements using report cards, we show that it is in the most competitive markets and those with the lowest average occupancy rates that improvements in the QM scores are more likely.
目前,医疗保险和医疗补助服务中心在养老院比较(NHC)网站上公布了15项质量指标(QM)。假定养老院能够在这些质量指标上有所改进,这样做就能吸引更多居民。在本调查中,我们研究了质量指标得分的变化情况,以及竞争和/或过度需求在1年时间里是否对这些变化得分产生了影响。
数据来源于NHC和在线调查认证与记录(OSCAR)系统。质量指标变化得分是根据2003年1月至2004年1月的值计算得出的。采用一系列回归分析来研究竞争和过度需求与质量指标得分之间的关联。
八项质量指标得分平均下降(即质量提高),六项质量指标得分平均上升(即质量下降)。然而,在14项质量指标中的13项,这些平均变化幅度均小于1%。回归分析表明,竞争加剧与质量指标得分提高之间存在关联,入住率降低与质量指标得分提高之间也存在关联。
正如基于使用成绩单进行质量改进的市场驱动机制所预测的那样,我们发现,在竞争最激烈的市场以及平均入住率最低的市场中,质量指标得分更有可能提高。
