The aim of the study was to evaluate the predictive validity of the Modified Fall Assessment Tool (MFAT) in a nursing home setting. The study involved 83 residents from a nursing home in Slovenia with an average age of 81 years. To determine the predictive characteristics of the MFAT, a receiver operating characteristic curve analysis was applied. During the observation period of 12 weeks, 18 residents fell. The fallers had a significantly higher history of falls, a higher number of diagnoses, more medication, and a higher MFAT score than the non-fallers. Using the estimated criterion of 20 points, the sensitivity of the MFAT score was 61%, its specificity was 80%, its classification accuracy was 64%, its positive likelihood ratio was 3.1, its negative likelihood ratio was 0.5, its positive predictive value was 46%, and its negative predictive value was 88%. The results showed that the MFAT is suitable for the prediction of falls and, hence, also the prevention of falls in nursing homes, whereby the recommended criterion score is 20 points.
本研究旨在评估改良跌倒评估工具（MFAT）在疗养院环境中的预测有效性。该研究涉及来自斯洛文尼亚一家疗养院的 83 名居民，平均年龄为 81 岁。为了确定 MFAT 的预测特征，应用了受试者工作特征曲线分析。在 12 周的观察期间，有 18 名居民跌倒。与非跌倒者相比，跌倒者有更高的跌倒史、更多的诊断、更多的药物治疗和更高的 MFAT 评分。使用估计的 20 分标准，MFAT 评分的敏感性为 61%，特异性为 80%，准确性为 64%，阳性似然比为 3.1，阴性似然比为 0.5，阳性预测值为 46%，阴性预测值为 88%。结果表明，MFAT 适用于预测跌倒，从而也适用于预防疗养院中的跌倒，建议的标准分数为 20 分。
