摘要
目的探讨以医院为基础的涂阴肺结核诊断评分模型。方法采用病例对照研究,选择涂阴活动性肺结核患者119例作为病例组,其他肺疾病患者79例作为对照组。记录所有患者的临床症状和实验室检查结果,选择与涂阴活动性肺结核相关的危险因素和症状进行多元Logistic分析,计算各变量的权重分数,建立临床诊断评分模型。结果根据此诊断评分模型对两组进行评分,病例组平均(21.3±3.0)分,对照组平均(15.3±3.4)分,二者比较P<0.01。选取评分>19分作为鉴别涂阴活动性肺结核和其他肺部疾病的临界值时,诊断的灵敏度和特异性均较理想,分别为84.9%(101/119),81.0%(64/79)。结论新建立的涂阴活动性肺结核诊断评分模型简便易行,有助于涂阴肺结核的早期诊断,尤其适合于无分枝杆菌培养条件的基层单位,具有进一步扩大论证的价值。
Objective To develop a diagnostic scoring model of smear negative active pulmonary tuberculosis(TB). Methods A hospita1-based case-control study was undertaken among a cohort comprised of 119 smear negative active pulmonary TB patients and 79 patients with other respiratory diseases who were hospitalized between Jun,2005 and Dec,2006.All patients were recorded with their symptoms and laboratory examinations.Risk factors and symptoms described in the documents were compared between these two groups.Significa...
