医务人员感染结核危险性的探讨

Risk of Tuberculosis Infection in Hospital Workers: A Discussion

目的探讨医务人员医院感染结核的危险性。方法采用分组对照研究的方法,检查组与对照组对结核菌素纯蛋白衍化物(PPD)试验的反应情况。结果医务人员PPD的阳性率达84.1%,对照组为52.1%,两组之间差异有非常显著性(P<0.001),其比值比(OR)为8.29;在医务人员中,非临床工作的医务人员受结核感染的机会与临床工作者相同(P>0.05);涉及呼吸道疾病科室的人员受结核感染的危险性最高,是普通科室的2.95倍。结论医院作为特殊的工作环境,对医务人员结核感染确实构成危胁,建议医务人员提高自我保护意识,积极预防医院感染,特别是刚刚步入医院工作、PPD反应呈阴性的医务工作者。

OBJECTIVE To discuss the risk of tuberculosis infection in a general hospital workers. METHODS in a cross-sectional survey, we studied purified protein derivative （PPD） test in exposure group and control group. RESULTS The positive rate of PPD test in the hospital workers was 84. 1%, significantly higher than that in controls （52.1%, P〈0. 001）. The OR was 8. 29. Among the hospital workers, the positive rate of PPD in clinic workers was not significantly different with that of non-clinic workers （P〉0.05）. The positive PPD in workers of respiratory department was 2. 95 times higher than in those of other departments. CONCLUSIONS The environment of hospital is special. Tuberculosis infection threatens the health of hospital workers. So we suggest that hospital workers improve self-protective consciousness and actively prevent tuberculosis infection, especially for internes and physicians with negative PPD.
