目的 探讨不同结核病控制策略与复治涂阳患者形成的关系。方法 对宁夏实施世界银行贷款结核病控制项目前后两个不同时期结核病统计报表进行统计学 χ2 检验及直线相关分析。结果 宁夏实施项目以前的结核病控制策略导致新发涂阳肺结核患者治愈率仅为 34 33% ,同期复治涂阳肺结核患者比例高达 6 8 79% ;实施直接面视下短程化学疗法策略 ,使新发涂阳患者治愈率提高到 95 %以上 ,同期 ,复治涂阳肺结核患者比例最低下降到 18 2 7%。经相关处理 ,新发涂阳肺结核患者的治愈率与复治涂阳患者的比例之间呈明显的负相关。结论 现代结核病控制的直接面视下短程化学疗法策略能大幅度地减少复治涂阳患者和耐多药结核患者的产生
Objective To explore the relationship between different tuberculosis control strategies and the formation of retreatment smear-positive patients. Methods The statistics χ2 test and linear correlation analysis of tuberculosis statistics in two different periods before and after the implementation of the World Bank Loan TB Control Project were carried out in Ningxia. Results The previous TB control strategy of Ningxia implemented project resulted in a cure rate of 34.33% for smear-positive tuberculosis patients and 68.89% for smear-positive pulmonary tuberculosis patients in the same period. The strategy of direct-face short-range chemotherapy was implemented to make new The cure rate of smear-positive patients increased to more than 95%. In the same period, the lowest proportion of smear-positive pulmonary tuberculosis patients was reduced to 182.7%. After the related treatment, the newly-established smear-positive pulmonary tuberculosis patients showed a significant negative correlation between the cure rate and the proportion of patients with relapsed and smear-positive patients. Conclusions Direct TBT in modern TB control strategies can significantly reduce the incidence of re-treatment smear-positive patients and MDR-TB patients
