目的：界定Waterlow量表对重症患者压疮的预测价值及诊断界值。方法回顾性分析765例重症患者的压疮风险评估资料，使用受试者工作特征(ROC)曲线评价Waterlow量表的预测性能和最佳诊断界值。结果由ROC分析结果可知，Waterlow评分曲线下面积为0.694，与0.5相比，具有统计学意义（P＜0.01）。 Waterlow量表分界值为20分时，其灵敏度（0.880）、特异度（0.480）具有最好的平衡性。结论 Waterlow量表在预测重症患者压疮中具有较高的灵敏度和特异度，可将分界值提高至20分。

Objective To explore the predictive value of Waterlow scale for pressure ulcers for critically ill patients and its cut-off value. Methods A retrospective analysis of evaluation data of pressure ulcer risk of 765 critically ill inpatients was conducted and predictive value and cut-off value of Waterlow scale was assessed by ROC (Receiver Operating Characteristic). Results ROC indicated that the area under curve was 0.694, which showed statistical significance ( P<0.01). When cut-off value of Waterlow sacle reached 20, the sensitivity (0.880) and specificity (0.480) of the scale reached a good balance. Conclusion Waterlow scale has high sensitivity and specificity in predicting pressure ulcers for critically ill patients and its cut-off value could be raised to 20.
