摘要
目的:评价误吸风险筛查表在神经系统肿瘤患者术后误吸评估中的预测效度。方法:采用巢式病例对照研究方法,选取开颅手术的168例患者为研究对象,应用误吸风险筛查表进行评分并记录误吸的发生情况。评估误吸实际发生率,计算尤登指数确定最佳预测临界值,计算受试者工作特征(receiver operating characteristic,ROC)曲线下AUC面积,计算筛查表的灵敏性、特异性、阳性预测值、阴性预测值。结果:实际发生误吸36例,误吸发生率为21.4%;误吸风险筛查表ROC曲线下面积AUC=0.806(95%CI=0.737~0.876,P<0.001),最佳预测临界值为6分,尤登指数取得最大值为0.452,此时,灵敏性和特异性分别为0.861和0.591,阳性预测值和阴性预测值分别为0.360和0.940。结论:误吸风险筛查表对误吸的评估预测效度较好,可作为神经系统肿瘤患者术后误吸风险评估工具。
Objective:To evaluate the predictive validity of the screening scale for risk of accidental aspiration in postoperative evaluation of patients with neurologic tumors.Methods:Using the prospective analysis method,168 patients underwent craniotomy enrolled in the study were evaluated by the screening scale for risk of accidental aspiration.The actual incidence of aspiration,the best predicted critical value,the AUC area under the receiver operating characteristic(ROC)curve,the sensitivity,specificity,positive prediction value,and negative predictive value of the screening scale were calculated.Results:The actual incidence of accidental inhalation was 21.4%;The AUC area under the ROC curve was 0.806(95%CI=0.737 to 0.876,P<0.001);The best predicted threshold of the scale was 6 points,and the Youdeng index reached a maximum of 0.452.At this time,the sensitivity and specificity were 0.861 and 0.591,and the positive and negative predictions were 0.360 and 0.940.Conclusion:The screening scale for risk of accidental aspiration has a good predictive effect and can be used as a risk assessment tool for patients with neurologic tumors after surgery.
