目的了解全市2012-2015年四年来涂阳肺结核密切接触者检查出活动性肺结核的检出率以及有关影响因素。方法对涂阳病人的密切接触者筛查,采用PPD试验、胸部X线检查、痰涂片检查和痰培养检查。结果我市涂阳肺结核密切接触者中活动性肺结核的检出率是3.54%,其中涂阳肺结核的检出率是1.23%,>60岁年龄组活动性肺结核检出率高于其他年龄组,经统计学处理,差异有统计学意义(P<0.05);排菌量3+的病人与排菌量2+的病人密切接触者活动性肺结核检出率差异有统计学意义(P<0.05)。结论涂阳肺结核密切接触者筛查是早期发现活动性肺结核的有效手段。
Objective To understand the detection rate of active pulmonary tuberculosis (TB) among the close contacts of smear-positive pulmonary tuberculosis (TB-TB) in 2012-2015 in the whole city and the related factors. Methods Sputum smear positive patients were screened closely. PPD test, chest X-ray examination, sputum smear test and sputum culture test were used. Results The detection rate of active pulmonary tuberculosis in smear-positive TB patients was 3.54% in our city, of which the detection rate of smear positive pulmonary tuberculosis was 1.23%. The detection rate of active pulmonary tuberculosis in> 60 years old group was higher than other age groups, The difference was statistically significant (P <0.05). There was significant difference in the detection rate of active pulmonary tuberculosis among the patients with 3+ . Conclusion Screening of close contact smear-positive pulmonary tuberculosis is an effective means to detect active pulmonary tuberculosis in the early stage.
