COMHON量表和Braden量表在ICU纵隔术后患者压力性损伤风险评估中的比较

Comparative study of the COMHON scale and the Braden scale in risk assessment of pressure injury for ICU patients after mediastinal surgery

目的比较COMHON量表和Braden量表在ICU纵隔手术后患者压力性损伤风险评估中的预测效能。方法便利选取胸腔外科行纵隔手术治疗后入住ICU的232例患者为研究对象,采用COMHON量表和Braden量表对其进行压力性损伤风险评估。结果在72 h观察期内共29例(12.5%)患者发生压力性损伤,分期均为1期。使用两种量表评估时,压力性损伤组与非压力性损伤组量表总评分差异有统计学意义(均P<0.01)。Braden量表ROC曲线下面积为0.747,当总分为13.5分时,约登指数为0.522,预测价值最大;COMHON量表ROC曲线下面积为0.976,当总分为9.5分时,约登指数为0.828,预测价值最大。结论Braden量表和COMHON量表均可有效评估ICU纵隔手术后患者压力性损伤发生风险,而COMHON量表的预测效能高于Braden量表。

Objective To compare the predictive effectiveness of the COMHON scale and the Braden scale in the risk assessment of pressure injury for ICU patients after mediastinal surgery.Methods A total of 232 ICU patients after mediastinal surgery from thoracic surgery department were selected conveniently,then they were conducted risk assessment of pressure injury using the COMHON scale and the Braden scale.Results During the 72 hours observation period,29 patients(12.5%)suffered from pressure injury,and all of them were in stage I.When the patients were assessed using the two scales,there were significant differences in the total scores between the pressure injury group and the non-pressure injury group(P<0.01 for both).The area under the ROC curve of the Braden scale was 0.747,and when the total score was 13.5,the Youden index was 0.522,which achieved the best predicted value;and the area under the ROC curve of the COMHON scale was 0.976,when the total score was 9.5,the Yoden Index was 0.828,which had the maximal predicted value.Conclusion Both the Braden scale and the COMHON scale can effectively assess the risk of pressure injury for ICU patients after mediastinal surgery,and the predictive performance of the COMHON scale is better than that of the Braden scale.
