目的:对涂阳肺结核患者密切接触者开展相关筛查并与既往的症状筛查进行比较,为提高活动性肺结核的阳性检出率提供科学依据,以有效控制结核病传染源。方法:采用问卷调查的方式,对1000人开展调查。结果:2011年活动性肺结核检出率为0.4%,阳性检出率为0.2%。2014年活动性肺结核检出率为1.6%,阳性检出率为1.2%。结论:贵州省于2012年起在全省范围内逐步推行将结核病的诊疗工作转入定点医疗机构,通过多种先进技术手段大大提高了活动性肺结核检出率和涂阳肺结核检出率。涂阳肺结核患者密切接触者筛查是发现结核新病例的一种有效手段。
OBJECTIVE: To carry out screening of patients with close contacts with smear-positive pulmonary tuberculosis and compare them with previous symptom screening to provide a scientific basis for raising the positive detection rate of active tuberculosis in order to effectively control the source of tuberculosis infection. Methods: A questionnaire survey was conducted on 1,000 people. Results: In 2011, the detection rate of active tuberculosis was 0.4% and the positive detection rate was 0.2%. In 2014, the detection rate of active tuberculosis was 1.6%, the positive detection rate was 1.2%. Conclusion: Since 2012, Guizhou Province has gradually implemented the diagnosis and treatment of tuberculosis in designated medical institutions throughout the province. Through various advanced technologies, the detection rate of active tuberculosis and the detection rate of smear-positive pulmonary tuberculosis have been greatly increased. Screening of close contacts of smear positive pulmonary tuberculosis patients is an effective means of finding new cases of tuberculosis.
