Munro评估量表与ELPO评估量表在术中患者压力性损伤风险评估中的效果比较*

目的:探讨采用Munro评估量表与ELPO评估量表对术中患者发生压力性损伤的风险性能评估效果。方法:采用病例对照研究方法,选取拟施行外科手术的患者312例作为研究对象,使用Munro评估量表与ELPO评估量表分别对术中患者进行压力性损伤的风险评估,计算受试者工作特征曲线下面积(AUC)、约登指数、灵敏度、特异度、阳性预测值与阴性预测值。结果:有29例患者发生压力性损伤,发生率为9.29 %。使用两种量表评估时,压力性损伤组与无压力性损伤组量表评分比较,差异具有统计学意义(P＜0.05); Munro评估量表与ELPO评估量表ROC曲线下面积分别为0.773、0.878,最佳阈值分别为23.5分、17.5分,说明此时量表的预测性能最好。结论:Munro评估量表与ELPO评估量表均能够评估手术患者压力性损伤的发生风险,但ELPO评估量表的预测性能高于Munro评估量表。

Comparison of the Munro scale and the ELPO scale for assessing the risk of pressure injuries in surgical patients

Objective: To explore the effect of Munro scale and ELPO scale on the risk efficacy of pressure injury in surgical patients. Methods: A case-control study was conducted to select 312 patients who were scheduled to undergo surgery as the research objects.The Munro scale and ELPO scale were used to assess the risk of pressure injury in patients during surgery, and the area under the receiver operating characteristic curve (AUC), ordon index, sensitivity, specificity, positive predictive value and negative predictive value were calculated. Results: A total of 29 patients with pressure injury, with an incidence of 9.29 %.When using the two scales for evaluation, there was a statistical difference in the scale scores between the pressure injury group and the non-pressure injury group (P<0.05).The areas under the ROC curve of Munro and ELPO scales were 0.773 and 0.878, respectively, and the optimal thresholds were 23.5 and 17.5 points,indicating that the scale had the best prediction performance. Conclusion: Both Munro and ELPO scales can assess the risk of pressure injury in surgical patients, but the predictive performance of ELPO scale is higher than that of Munro scale.
