摘要

目的:评价和确定Braden-Q儿童压疮评估量表用于诊断住院患儿压疮高风险的最佳临界值。方法:对2014年1至6月在我院住院且Braden-Q量表≤24分的372例患者进行住院期间压疮发生情况追踪分析

采用灵敏度、特异度、阳性预测值、阴性预测值、约登指数和受试者工作特征曲线（receiver operating characteristic

ROC）确定和评价Braden-Q量表诊断压疮高度危险的临界值。结果:372例研究对象中有37.73%的患者Braden-Q评分≤16分（最低11分）

72.27%的患者Braden-Q评分17

4分;共发生院内压疮21例

其分值主要集中在13

6分。当Braden-Q量表诊断压疮高危的临界值为16分时

其预测压疮危险的灵敏度为0.826

特异度为0.759

阳性预测值为0.185

阴性预测值为0.985

约登指数（0.585）较其他临界值更大

Braden-Q量表ROC曲线下面积（area under curve

AUC）为0.923。结论:Braden-Q量表16分是诊断儿童压疮高度危险的最佳临界值

能够很好地预测儿童发生压疮的风险

具有较高的诊断价值。

Abstract

Objective:To determine the high risk cut-off point of Braden-Q scale when being applied to predict children’s pressure ulcer risk. Methods:The occurrence of pressure ulcers in 372 in-patient children in our hospital with their Braden-Q score no more than 24 point were monitored and accessed from Jannuaray to June in 2014. By observing their sensitivity

specificity

positive predictive value

negative predictive

Jorden index and receiver operating characteristic curve(ROC)

the high risk cut-off point of Braden-Q scale was evaluated and determined. Results:Of the 372 patients

37.73% had Braden-Q score ≤ 16 points(the lowest 11points)and 72.27% had Braden-Q score of 17-24 points. Twenty-one patients finally developed pressure ulcers. Their Braden-Q scores varied between 13 points and 16 points. Sixteen point was set to be the cut-off point of Braden-Q scale

which best predicted the risk of pressure ulcers with sensitivity of 0.826

specificity of 0.759

positive predictive value of 0.185

and negative predictive value of 0.985;and the area under ROC(AUC) is 0.923. Conclusion:Braden-Q scale is reliable in forecasting occurrence risk of children’s pressure ulcers

and 16 is the optimal point in diagnosing high risk of pressure ulcer.
