the main objective was to evaluate if the admission functional independence measure (FIM) score could be used to predict the risk of falls in geriatric inpatients.
a 10-year retrospective study was performed.
the study was conducted in a 298-bed geriatric teaching hospital in Geneva, Switzerland.
all patients discharged from the hospital from 1 January 1997 to 31 December 2006 were selected.
measures used were FIM scores at admission using the FIM instrument and number of falls extracted from the institution's fall report forms.
during the study period, there were 23,966 hospital stays. A total of 8,254 falls occurred. Of these, 7,995 falls were linked to 4,651 stays. Falls were recorded in 19.4% of hospital stays, with a mean incidence of 7.84 falls per 1,000 patients-days. Although there was a statistically significant relationship between total FIM score, its subscales, and the risk of falling, the sensitivity, specificity, positive predictive value and negative predictive value obtained with receiver operating characteristic curves were insufficient to permit fall prediction. This might be due in part to a non-linear relationship between FIM score and fall risk.
in this study, the FIM instrument was found to be unable to predict risk of falls in general geriatric wards.
主要目的是评估入院时的功能独立性测量（FIM）评分是否可用于预测老年住院患者的跌倒风险。
回顾性研究。
瑞士日内瓦的一家 298 床老年教学医院。
选择了 1997 年 1 月 1 日至 2006 年 12 月 31 日出院的所有患者。
采用 FIM 工具评估入院时的 FIM 评分和从机构跌倒报告表中提取的跌倒次数。
在研究期间，共有 23966 例住院治疗。共发生 8254 例跌倒事件。其中 7995 例跌倒与 4651 例住院有关。住院患者中有 19.4%发生跌倒，每 1000 名患者日发生 7.84 例跌倒。尽管总 FIM 评分及其亚量表与跌倒风险之间存在统计学显著关系，但接收者操作特征曲线获得的敏感性、特异性、阳性预测值和阴性预测值不足以预测跌倒。这可能部分归因于 FIM 评分与跌倒风险之间的非线性关系。
在这项研究中，发现 FIM 工具无法预测普通老年病房的跌倒风险。
