To examine rates of hospice disenrollment and posthospice hospitalization among patients who are enrolled in hospices that provide continuous home care (CHC) (CHC hospices) compared with patients who are enrolled in hospices that do not offer CHC (non-CHC hospices).
We performed a retrospective cohort study among Medicare fee-for-service decedents between July and December 2011, who were 66 years and older and had used hospice in their last 6 months of life. We used propensity score matching to account for potential confounding characteristics of hospices. Generalized estimating equation models were applied to estimate between CHC hospices and non-CHC hospices the associations of hospice disenrollment/hospitalization, adjusted for patient characteristics. We also conducted subgroup analyses to examine how the association might have differed by hospice size, and by the percentage of enrollees who received CHC.
After matching, we identified 936 pairs of CHC and non-CHC hospices, well balanced in terms of organizational characteristics. In fully adjusted models, compared with non-CHC hospices, CHC hospices had significantly lower disenrollment rates (adjusted rate ratio, 0.73; 95% confidence interval, 0.60-0.87), and lower hospitalization rates (adjusted rate ratio, 0.79; 95% confidence interval, 0.66-0.95). These associations were significantly more pronounced among larger hospices (those with >175 enrollees during study period), and among hospices in which at least 7.3% of enrollees used CHC.
CHC hospices had significantly lower rates of hospice disenrollment and posthospice hospitalization, suggesting CHC service available may enable higher quality of end-of-life care.
与未提供持续居家护理(CHC)的临终关怀机构(非CHC临终关怀机构)的患者相比,研究接受提供CHC服务的临终关怀机构(CHC临终关怀机构)的患者的临终关怀退出率和临终关怀后住院率。
我们对2011年7月至12月期间66岁及以上、在生命的最后6个月使用过临终关怀服务的医疗保险按服务收费的死者进行了一项回顾性队列研究。我们使用倾向评分匹配来考虑临终关怀机构的潜在混杂特征。应用广义估计方程模型来估计CHC临终关怀机构和非CHC临终关怀机构之间临终关怀退出/住院的关联,并对患者特征进行了调整。我们还进行了亚组分析,以研究这种关联在临终关怀机构规模以及接受CHC服务的参保者百分比方面可能存在的差异。
匹配后,我们确定了936对CHC和非CHC临终关怀机构,在组织特征方面平衡性良好。在完全调整模型中,与非CHC临终关怀机构相比,CHC临终关怀机构的退出率显著更低(调整率比为0.73;95%置信区间为0.60 - 0.87),住院率也更低(调整率比为0.79;95%置信区间为0.66 - 0.95)。这些关联在规模较大的临终关怀机构(研究期间参保者超过175人的机构)以及至少7.3%的参保者使用CHC服务的临终关怀机构中更为显著。
CHC临终关怀机构的临终关怀退出率和临终关怀后住院率显著更低,这表明可获得的CHC服务可能有助于提高临终护理质量。
