肺结核复发危险因素logistic回归分析

目的 分析湖北省涂阳肺结核愈后5年复发的危险因素。方法 对湖北省10县(市)1995年登记的治愈涂阳肺结核患者进行追踪调查和痰菌复查,对影响结核病复发的有关因素进行非条件logistic回归分析,计算比值比(OR)。结果 湖北省1995年治愈的涂阳肺结核患者复发率为3.85％。非示范县、3个月末痰菌、结核病复治、化疗管理方式和就诊于非结防机构最终进入多因素分析的回归模型,OR值分别为0.15、4.62、3.68、5.88和6.47。结论 采取标准化、规范化的全程督导化疗方案,归口管理肺结核患者能降低涂阳肺结核的复发。

Logistic analysis on risk factors related to smear positive pulmonary tuberculosis

Objective To explore the risk factors on relapsing tuberculosis related to smear positive pulmonary tuberculosis which had been cured for five years. Methods Patients with smear positive pulmonary tuberculosis registered in 1995 from ten countries in Hubei province were studied and logistic regression was used for data analysis. Results The 5-year relapse rate of smear positive pulmonary tuberculosis was 3.85 percent. Risk factors related to relapse would include being non-modeled county, negative smear after treated for three months, the class of retreatment, management of non-DOTS, method of chemotherapy and patients that did not get treated by the tuberculosis institute, with odds ratios of 0.15,4.62,3.68,5.88 and 6.47, respectively. Conclusion Effect standard, regulation DOTS and the centralized management measure might have had effects on decreasing the relapse rate.
