湖州市结核病防治医务人员结核菌感染现况调查研究

Survey on the tuberculosis infection among health care workers for tuberculosis in Huzhou city

目的了解从事结核病防治医务人员结核菌感染情况,为采取有效预防控制措施,降低结核感染风险提供参考依据。方法采用整群方便抽样方法,对湖州市结核病防治医务人员进行问卷调查。使用γ-干扰素释放试验检测结核菌感染情况。采用非条件logistic回归分析影响因素。结果检验人员、护士、临床医生、管理以及其他人员感染率分别为45.53%、31.82%、25.00%、18.18%和6.25%。多因素logistic分析表明,检验人员、护士的OR值分别为30.81和15.88,差异有统计学意义(P<0.05)。与佩戴N95口罩相比,佩戴棉纱口罩感染风险OR值为12.56,差异有统计学意义(P<0.05)。结论从事结核病防治检验人员及护士的感染率风险较高。不建议使用棉纱口罩进行感染防控。

Objective To understand the current status of tuberculosis（TB）infection among health care workers for TB prevention,control and treatment in Huzhou city,and to provide relevant reference for effective TB prevention and control in order to reduce the risk of TB infection. Methods A questionnaire survey was conducted among medical personnel specialized in TB prevention and treatment randomly selected using cluster convenience sampling method.γ-interferon release assay was performed to determine TB infection.Unconditional logistic regression was used for data analysis. Results The TB infection rates were45.53%,31.82%,25.00%,18.18% and 6.25% among lab technicians,nurses,clinicians,administrative personnel and others.Logistic regression analysis showed that,the odds ratio（OR）was 30.81 for lab technicians and 15.88 for nurses,the difference was significant（P〈0.05）.The risk of TB infection was higher among medical personnel wearing cotton masks（OR=12.56）than those wearing N95 masks,the difference was also statistically significant（P〈0.05）. Conclusions Lab technicians and nurses are at higher risk of TB infection and cotton masks are not recommended to use for TB health care workers.
