河南省结核病防治机构工作人员结核病感染率调查

A survey on the infection rate of tuberculosis among employees of the antituberculosis institutions in Henan province,China

目的了解河南省结核病防治机构工作人员结核病感染情况。方法于2005年1月从河南省109个县中随机抽取40个县，对抽取的县及所有市级结核病防治机构（18个）的所有在职工作人员（独立结核病防治机构调查对象为全体职工，非独立结核病防治机构调查对象为从事结核病诊治、检查、督导、检验、护理等所有医务人员以及所属行政后勤人员）作为调查对象；对调查对象进行PPD皮试检查。结果2153人接受了PPD皮试检查，阳性率为60．6％，其中医务人员的阳性率为66．1％，根据市、地与县级工作人员数权重进行加权调整后全省结核病防治机构工作人员的PPD阳性率为57．3％，医务人员的阳性率为62．8％。经X^2检验，PPD皮试阳性率与强阳性率医务人员均显著高于非医务人员，市级工作人员均显著高于县级工作人员，30岁以上年龄组较高，不同BCG接种史、不同性别之间无显著差别。多因素分析前三者差异有统计学意义。结论河南省结核病防治机构内结核病感染控制工作较为薄弱，机构内工作人员尤其是医务工作人员工作环境结核病感染暴露危险较高。
