两种量表评分在老年脑血管意外患者压力性损伤风险评估中的效果比较

A comparison between two scales in risk assessment of stress injury in elderly patients with cerebrovascular accident

目的:比较Braden量表和Waterlow量表在老年脑血管意外患者压力性损伤风险评估中的效果。方法:选取2018年1月至2019年12月温州医科大学附属第一医院神经内科及老年病科的老年脑血管意外患者244例为研究对象,分别采用Braden量表和Waterlow量表对患者进行连续评估,计算各量表灵敏度、特异度、阳性预测值、阴性预测值、Youden指数、ROC曲线下面积(AUC)。结果:Braden量表最佳临界值为17分,预测压力性损伤发生的灵敏度为93.33%,特异度为62.00%,阳性预测值为13.86%,阴性预测值为99.30%;Waterlow量表最佳临界值为15分,预测压力性损伤发生的灵敏度为93.33%,特异度为81.67%,阳性预测值为25.00%,阴性预测值为99.47%;Waterlow量表的AUC为0.94,显著大于Braden量表的0.87(P<0.05)。结论:Waterlow量表在老年脑血管意外患者压力性损伤风险评估中的效果较Braden量表好。

Objective:To compare the effect of Braden scale and Waterlow scale in the risk assessment of stress injury in elderly patients with cerebrovascular accident.Methods:Totally 244 elderly inpatients with cerebrovascular accident were selected and evaluated by Braden scale and Waterlow scale.The sensitivity,specificity,positive predictive value,negative predictive value,Youden index,AUC(area under the ROC curve)of each scale were calculated.Results:The best critical value of Braden scale was 17 points,and the sensitivity,specificity,positive predictive value and negative predictive value of Braden scale was 93.33%,62.00%,13.86%and 99.30%,respectively.In contrast,the best critical value of Waterlow scale was 15 points,and the sensitivity,specificity,positive predictive value and negative predictive value of Waterlow scale was 93.33%,81.67%,25.00%and 99.47%,respectively.AUC of Waterlow scale(0.94)was significantly higher than that of Braden scale(0.87)(P<0.05).Conclusion:The application of Waterlow scale in stress injury risk assessment of elderly patients with cerebrovascular accident is more valuable than Braden scale.
