目的了解邵东县涂阳肺结核患者的转阴情况及其影响因素,探索相应防治对策。方法选择县疾控中心登记肺结核患者的病历资料,分析涂阳肺结核患者转阴率、构成比及其分布特点和变化规律。结果邵东县涂阳肺结核患者的总转阴率为94.42%,初治涂阳肺结核患者高于复治涂阳肺结核患者(P<0.01),菌阳等级越高转阴率下降(P<0.01),随着年龄升高转阴率降低(P<0.05)。结论涂阳肺结核患者的转阴率与病人类型、菌阳等级、年龄等因素有关,应针对重点环节开展防治工作,提高涂阳肺结核患者的转阴率和治愈率。
Objective To understand the overcast negative condition and its influencing factors of smear positive pulmonary tuberculosis patients in Shaodong County and to explore the corresponding control measures. Methods Select the records of patients with tuberculosis registered in the CDC of the county to analyze the negative conversion rate, composition ratio, distribution characteristics and changes of smear positive pulmonary tuberculosis patients. Results The total negative conversion rate of smear positive tuberculosis patients in Shaodong County was 94.42%. The newly diagnosed smear positive pulmonary tuberculosis patients were higher than that of patients with relapsed smear positive pulmonary tuberculosis (P <0.01) , And the rate of negative conversion decreased with age (P <0.05). Conclusions The negative conversion rate of smear positive pulmonary tuberculosis patients is related to the type of patient, grade and age of bacteria, and other factors. Prevention and treatment work should be carried out in key areas so as to improve the rate of negative conversion and the cure rate of smear positive pulmonary tuberculosis patients.
