This study examines the effect of strategic group membership on nursing home performance and strategic behavior.
Data from the 1987 Medicare and Medicaid Automated Certification Survey were combined with data from the 1987 and 1989 Pennsylvania Long Term Care Facility Questionnaire. The sample consisted of 383 Pennsylvania nursing homes.
Cluster analysis was used to place the 383 nursing homes into strategic groups on the basis of variables measuring scope and resource deployment. Performance was measured by indicators of the quality of nursing home care (rates of pressure ulcers, catheterization, and restraint usage) and efficiency in services provision. Changes in Medicare participation after passage of the 1988 Medicare Catastrophic Coverage Act (MCCA) measured strategic behavior. MANOVA and Turkey HSD post hoc means tests determined if significant differences were associated with strategic group membership.
Cluster analysis produced an optimal seven-group solution. Differences in group means were significant for the clustering, performance, and conduct variables (p < .0001). Strategic groups characterized by facilities providing a continuum of care services had the best patient care outcomes. The most efficient groups were characterized by facilities with high Medicare census. While all strategic groups increased Medicare census following passage of the MCCA, those dominated by for-profits had the greatest increases.
Our analysis demonstrates that strategic orientation influences nursing home response to regulatory initiatives, a factor that should be recognized in policy formation directed at nursing home reform.
本研究考察战略群组归属对疗养院绩效和战略行为的影响。
1987年医疗保险和医疗补助自动认证调查的数据与1987年和1989年宾夕法尼亚长期护理机构调查问卷的数据相结合。样本包括383家宾夕法尼亚州的疗养院。
聚类分析用于根据衡量范围和资源配置的变量将383家疗养院划分为不同的战略群组。绩效通过疗养院护理质量指标(压疮发生率、导尿率和约束使用率)以及服务提供效率来衡量。1988年《医疗保险灾难性保险法案》(MCCA)通过后医疗保险参与情况的变化衡量战略行为。多变量方差分析和土耳其HSD事后均值检验确定是否存在与战略群组归属相关的显著差异。
聚类分析得出了一个最优的七组解决方案。聚类、绩效和行为变量的组均值差异显著(p <.0001)。以提供连续护理服务的设施为特征的战略群组患者护理结果最佳。效率最高的群组以医疗保险普查人数多的设施为特征。虽然所有战略群组在MCCA通过后医疗保险普查人数都有所增加,但以营利性机构为主导的群组增幅最大。
我们的分析表明,战略导向会影响疗养院对监管举措的反应,这一因素在针对疗养院改革的政策制定中应得到认可。
