3种评估表预测压疮效果的比较研究

Predicting pressure sore risk with the Braden(modified),Norton and WCUMS Scales

目的 :比较 3种压疮危险性评估表Braden评估表 (修订版 )、Norton评估表、华西医科大学评估表 (WestChinaUniversitymedicalSciencesScale,简称WCUMS评估表 )的预测效果 ,寻找一种最适合国情、有效而可靠的压疮评估表 ,合理利用人力资源 ,及时指导护士对压疮高危患者采取预防性护理措施。方法 :3名护士分别运用 3种评估表 ,同时、独立地对同一病人进行评估 ,共有 2 2 2名病人接受评估。结果 :Braden评估表 (修订版 )与Norton评估表、WCUMS评估表比较 ,能较好平衡敏感度和特异度 (首末次评分临界值均为 2 2分 )。 3种评估表都有相对较高的阴性预测值 (≥ 98% ) ,但阳性预测值均偏低。结论 :Braden评估表 (修订版 )压疮预测效果较好 ,可以在压疮高发的人群中应用。

Objectives: To compare the predictive power of the three pressure sore risk calculators: Braden (modified), Norton and WCUMS (West China University medical Sciences Scale) scales. Method: Two hundred and twenty-two patients, free of pressure sore on admission, were assessed using the three scales by the three independent assessors. Results: Braden (modified) scale demonstrated better balance of sensitivity and specificity at the cut-off core of 22 than the other two scales. All three scales had high negative predictive values (≥98%), while the positive predictive value was low. Conclusions: The Braden (modified) scale is a more effective in pressure sore risk prediction and more suitable for use in clinical settings particularly where the incidence rate of pressure sore is high.
