摘　　要：目的根据Norton压疮评估量表单次评估的结果，评价预测神经系统疾病患者压疮的能力。方法回顾分析82例因神经系统疾病住院患者，将其分为压疮组和无压疮组。对两组Norton量表参数、总分进行比较，对Norton总分进行Logistic回归分析，计算各个切分点的敏感度、特异度、Youden指数，并绘制接受者工作特征曲线（ROC曲线），计算曲线下面积。结果压疮组的Norton总分为（17.11±4.71），无压疮组为（24.33±4.16）分，两组比较，差异有统计学意义（t=7.13，P〈0.01）。两组9项参数评分中，年龄、皮肤状况、身体状况评分比较，差异无统计学意义（P〉0.05），而其余6项参数评分，压疮组均低于无压疮组，差异有统计学意义（t值分别为6.35，7.3，6.58，7.85，4.33，5.49；P〈0.01）。Logistic回归分析显示，Norton总分预测压疮的能力有统计学意义（z=-4.6，P〈0.01），优势比为0.713。ROC曲线下面积为0.87，95%置信区间为0.784-0.944。结论单次的Norton评分对于神经系统疾病患者住院期间压疮的发生有一定的预测能力。Objective To analyze the predictive ability of single assessment by Norton scale in neurological diseases patients. Methods Totals of 82 cases of neurological diseases were selected, which were divided into pressure ulcer group and non-pressure ulcer group. The parameter and total score of Norton scale were analyzed by t-test. Logistic regression analysis was used for Norton score and the receiver operating characteristic curve （ ROC ） was performed. The sensitivity, specificity and Youden＇ s index of different cutoff points were calculated. Results The total score in the pressure ulcer group was lower than that of non-pressure ulcer group [ （ 17. 11± 4.71 ） vs （ 24.33 ± 4.16 ） ], and there was significant difference （ t = 7.13, P 〈 0.01 ）. Among the nine parameters, the age, skin status and body status were of no difference statistically between two groups, while the other six parameters in pressure group was significantly lower than those of non- pressure ulcer group （ t = 6.35,7.3,6.58,7.85,4.33,5.49 ;P 〈 0.01 ）. Logistic analysis revealed that Norton score had predictive value, the odd ratio of which was 0. 713 （z = - 4.6, P 〈 0.01 ）. The area of the ROC curve was 0.87, the 95% confidence interval of which was 0. 784 - 0. 944. Conclusions Single assessment of Norton scale has certain predictive ability of pressure ulcer for the patients with neurological diseases.
