摘要

目的：本院於2009年開始採用以STRATIFY量表為基礎進行跌倒危險評估，針對2017年跌倒危險評估量表修訂版進行準確度研究。材料與方法：本研究回溯2017年3月至12月之成年病人跌倒評估量表資料與異常事件。並以ROC（Receiver Operating Characteristic）曲線、Youden index與邏輯斯迴歸進行資料分析。結果：研究結果顯示修訂版跌倒評估量表之AUC（Area Under Curve）值為0.81，最佳切點為1分。以1分與2分為切點之敏感度（86.64% v.s. 83.87%），與特異度（60.91% v.s. 68.35%）並無差異。結論：研究顯示量表AUC為0.81，具優良鑑別力。另，視覺不良影響生活功能可視為跌倒高危險群之保護因子，照顧者因素亦為本土化重要之跌倒高危險因子，此結果可作為未來調整跌倒評估量表內容之依據。

Objective: Since 2009, our hospital has used the STRATIFY risk assessment tool for fall assessment. This study aimed to evaluate the accuracy of the revised 2017 Fall Risk Assessment Scale. Methods: The hospital records were analyzed to extract information regarding adult inpatients who underwent fall risk assessment and adverse events from March to December 2017. Data were analyzed using receiver operating characteristics analysis, Youden index, and logistic regression analysis. Results: The area under curve (AUC) value of the revised Fall Risk Assessment Scale was 0.81, and the cutoff point was 1. The sensitivity (86.64% vs. 83.87%) and specificity (60 .91% vs. 68.35%) were nonsignificantly different at cutoff points 1 and 2. Conclusions: The AUC value of the revised Fall Risk Assessment Scale was 0.81, indicating that the scale has excellent discriminating power. In addition, the study demonstrated that poor vision, which affects life functions, serves as a protective factor among patients with high fall risks. Furthermore, caregiver factors are crucial local high-risk factors. These results could be used for adjusting the Fall Risk Assessment Scale in future.
