目的 评价Braden-Q儿童压疮危险评估量表（Braden-Q量表）对儿科重症患者发生压疮的预测效度。方法 采用前瞻性队列研究设计方法，利用方便抽样在上海市三家儿童医院的重症监护室实际收集样本111例。由两名临床护士担任数据收集员，分别负责Braden-Q量表评分和皮肤评估，两者分别独立进行。结果 实际发生压疮7例，发生率为6.3%。当Braden-Q量表评分为17分时认为有发生压疮的危险，即17分为预测临界值，此时灵敏度为0.571，特异度为0.365，量表的受试者工作特征曲线下面积为0.547。结论 Braden-Q量表对儿科重症患者发生压疮风险的预测效度一般，有待进一步改进完善。

Objective To evaluate the predictive validity of Braden Q pediatric pressure ulcer risk assessment scale (Braden-Q scale) in severe pediatric patients. Methods The prospective cohort study design was adopted, and 111 samples were collected from intensive care units of three pediatric hospitals in Shanghai with convenience sampling. Two nurses were appointed as the data collector, and were in charge of the scoring of Braden-Q scale and skin assessment. Results Seven patients (6.3%) developed pressure ulcers. The cutoff score of Braden-Q scale was 17 for the risk of pressure ulcer, with the sensitivity of 0.571, specificity of 0.365 and area under receiver operating characteristic curve of 0.547. Conclusion The predictive validity of Braden-Q scale in severe pediatric patients is ordinary, and there is room for improvement.
