本文以通县5年内涂阳登记病例为对象,分析了不同痰菌转阴次数对涂阳登记率的影响。以末次痰菌转阴所计算的年底涂阳登记率,虽低于三次痰菌转阴所计算的结果,但涂阳登记率下降比值、相对系数、变化速度所反映的疫情趋势以及用于考核化疗效果,两者均呈一致性。作者认为,以末次痰菌转阴为准,统计年底涂阳登记率,用于结防工作是可行的。 In this paper, Tongxian smear-positive cases registered within 5 years as the object, analyzed the different sputum bacilli negative affect the registration rate of smear positive.
