Waterlow压力性损伤量表与Braden压力性量表在预测ICU病人压疮预防中的价值

目的 探究Waterlow压力性损伤量表与Braden压力性量表在预测ICU病人压疮预防中的价值。 方法 选取724例病人作为研究对象，采用Waterlow量表和Braten量表对病人压疮情况进行预测，并与最终压疮发生结果比较，观察2种量表的预测价值。 结果 Waterlow评分量表中，真阳性44例，真阴性600例；灵敏度为100.00%，特异度为88.23%。Braden评分量表真阳性为44例，真阴性为178例；灵敏度100.00%，特异度73.82%；Waterlow评分量表在特异度和阴性预测值上高于Braden评分量表（P < 0.01），但在敏感度和阳性预测值上差异无统计学意义（P>0.05）。在ROC曲线中，Waterlow量表曲线下面积为0.770（P < 0.05），略高于Braten评分量表曲线下面积的0.704（P < 0.05）。 结论 对ICU病人压疮预防过程中，Waterlow评分量表与Braden评分量表相比，特异性较好；但临床实际中，护理人员需根据量表采取针对性的护理措施。

Value of the Waterlow stress injury scale and Braden stress scale in predicting the prevention of pressure ulcer in ICU patients

Objective To explore the value of the Waterlow pressure injury scale and Braden stress scale in predicting the prevention of pressure ucler in ICU. Methods The Waterlow scale and Braten scale were used to predict the pressure ulcers of 724 patients, the predictive value of two scales were compared with the final pressure ulcers, and the predictive value of two scales were analyzed. Results The true positive in 44 cases and true negative in 600 cases were identified using the Waterlow rating scale, and the sensitivity and specificity of which were 100.00% and 88.23%, respectively.The true positive in 44 cases and true negative in 178 cases were identified using the Braden rating scale, and the sensitivity and specificity of which were 100.00% and 73.82%, respectively.The specificity and negative predictive value of Waterlow rating scale were significantly higher than those of Braden rating scale(P < 0.01), and the differences of the sensitivity and positive predictive value bewteen the two scales were not statistically significant(P>0.05).The area under the Waterlow rating scale curve(0.770) was slightly higher than that of Braten rating scale curve(0.704) (P < 0.05). Conclusions During the process of pressure ulcer prevention in ICU patients, the specificity of Waterlow rating scale is better than that of Braden rating scale.In clinical practice, the nursing staff should take specific nursing measures according to the scale.
