A national quality report card for nursing homes, Nursing Home Compare, has been published since 2002. It has been shown to have some, albeit limited, positive impact on quality of care. The objective of this study was to test empirically the hypothesis that nursing homes have responded to the publication of the report by adopting cream skimming admission policies.
The study included all non-Medicare newly admitted patients to all Medicare- and Medicaid-certified nursing homes nationally during the 2001-2005 period. Using the Minimum Data Set data, we calculated for each quarter several admission cohort characteristics: average number of activity of daily living limitations and percent of residents admitted with pain, with pressure ulcers, with urinary incontinence, with diabetes, and with memory limitations. We tested whether residents admitted in the postpublication period were less frail and sick compared with residents admitted in the prepublication period by estimating fixed facility effects longitudinal regression models. Analyses were stratified by nursing home ownership, occupancy, reported quality ranking, chain affiliation, and region.
Evidence for cream skimming was found with respect to pain and, to a lesser degree, with respect to memory limitation but not with respect to the 4 other admission cohort characteristics.
Despite the theoretical expectation, empirical evidence suggests only a limited degree of cream skimming. Further studies are required to investigate this phenomenon with respect to other admission cohort characteristics and with respect to post-acute patients.
自 2002 年以来,一直发布针对养老院的全国质量报告卡——“养老院比较”。该报告卡已被证明对护理质量有一定的、尽管是有限的积极影响。本研究的目的是通过实证检验以下假设,即养老院通过采用择优录取的入院政策对报告的发布做出了回应。
该研究包括在 2001 年至 2005 年期间,全国所有医疗保险和医疗补助认证的养老院中所有非医疗保险新入院的患者。我们使用最低数据集数据,为每个季度计算了几项入院患者群体特征:日常生活活动能力受限的平均数量以及疼痛、压疮、尿失禁、糖尿病和记忆力受限的居民入院比例。我们通过估计固定设施效果纵向回归模型,测试了与报告发布前相比,发布后入住的居民是否身体更健康、病情更轻。分析按养老院的所有权、入住率、报告的质量排名、连锁附属关系和地区进行分层。
在疼痛方面发现了择优录取的证据,而在记忆力受限方面则有一定程度的证据,但在其他 4 项入院患者群体特征方面则没有发现证据。
尽管存在理论预期,但实证证据表明,择优录取的程度有限。需要进一步研究以调查这种现象在其他入院患者群体特征以及急性后期患者方面的情况。
