Understanding the association between cognitive impairment severity and potentially avoidable readmissions (PARs) in older patients may facilitate the identification of at-risk individuals who would benefit from readmission prevention measures.
This retrospective cohort study was conducted using claims data linked with routinely collected cognitive impairment assessment results from a general acute care hospital in Tokyo, Japan. Patients were 65 years or age or older who were discharged from the subject hospital to home or a facility between July 2016 and September 2018.
A multivariable logistic regression analysis adjusted for covariates showed that the odds of PARs within 90 days to the subject hospital for patients with moderate and severe cognitive impairment were 1.418 times (95% confidence interval: 1.005-2.002) and 2.212 times (95% confidence interval: 1.206-4.058) higher, respectively, that for patients with normal cognition.
Older inpatients with later-stage cognitive impairment may represent a suitable target population for transitional care programs aimed at reducing readmissions.
了解老年患者认知障碍严重程度与潜在可避免再入院（PARs）之间的关联，可能有助于识别那些将从再入院预防措施中受益的高危个体。
本回顾性队列研究使用了与日本东京一家综合急性护理医院常规收集的认知障碍评估结果相关的索赔数据。患者为2016年7月至2018年9月期间从该主题医院出院回家或前往机构的65岁及以上老人。
对协变量进行调整的多变量逻辑回归分析显示，中度和重度认知障碍患者在90天内再次入住该主题医院的PARs几率分别比认知正常患者高1.418倍（95%置信区间：1.005 - 2.002）和2.212倍（95%置信区间：1.206 - 4.058）。
患有晚期认知障碍的老年住院患者可能是旨在减少再入院的过渡性护理项目的合适目标人群。
