Objective

To evaluate the risk factors associated with 30- and 90-day hospital readmissions in geriatric rehabilitation inpatients.

Design

Observational, prospective longitudinal inception cohort.

Setting

Tertiary hospital in Victoria, Australia.

Participants

Geriatric rehabilitation inpatients of the REStORing Health of Acutely Unwell AdulTs (RESORT) cohort evalutated by a comprehensive geriatric assessment including potential readmission risk factors (ie, demographic, social support, lifestyle, functional performance, quality of life, morbidity, length of stay in an acute ward). Of 693 inpatients, 11 died during geriatric rehabilitation. The mean age of the remaining 682 inpatients was 82.2±7.8 years, and 56.7% were women.

Interventions

Not applicable.

Main Outcome Measures

Thirty- and 90-day readmissions after discharge from geriatric inpatient rehabilitation.

Results

The 30- and 90-day unplanned all-cause readmission rates were 11.6% and 25.2%, respectively. Risk factors for 30- and 90-day readmissions were as follows: did not receive tertiary education, lower quality of life, higher Charlson Comorbidity Index and Cumulative Illness Rating Scale (CIRS) scores, and a higher number of medications used in the univariable models. Formal care was associated with increased risk for 90-day readmissions. In multivariable models, CIRS score was a significant risk factor for 30-day readmissions, whereas high fear of falling and CIRS score were significant risk factors for 90-day readmissions.

Conclusions

High fear of falling and CIRS score were independent risk factors for readmission in geriatric rehabilitation inpatients. These variables should be included in hospital readmission risk prediction model developments for geriatric rehabilitation inpatients.

老年康复患者再入院的风险因素：RESORT

客观的

评估与老年康复住院患者 30 天和 90 天再入院相关的风险因素。

设计

观察性、前瞻性纵向起始队列。

环境

澳大利亚维多利亚的三级医院。

参与者

急性不适成人恢复健康 (RESORT) 队列的老年康复住院患者通过综合老年评估进行评估，包括潜在的再入院风险因素（即人口统计学、社会支持、生活方式、功能表现、生活质量、发病率、住院时间）急性病房）。在 693 名住院患者中，11 人在老年康复期间死亡。其余 682 名住院患者的平均年龄为 82.2±7.8 岁，56.7% 为女性。

干预

不适用。

主要观察指标

老年住院康复出院后 30 天和 90 天再入院。

结果

30 天和 90 天非计划全因再入院率分别为 11.6% 和 25.2%。30 天和 90 天再入院的风险因素如下：未受过高等教育、生活质量较低、查尔森合并症指数和累积疾病评定量表 (CIRS) 得分较高，以及单变量模型中使用的药物数量较多. 正规护理与 90 天再入院的风险增加有关。在多变量模型中，CIRS 评分是 30 天再入院的重要危险因素，而高度害怕跌倒和 CIRS 评分是 90 天再入院的重要危险因素。

结论

高度害怕跌倒和CIRS评分是老年康复住院患者再入院的独立危险因素。这些变量应包括在老年康复住院患者的再入院风险预测模型开发中。
