传染病医院医务人员结核感染状况

Survey on tuberculosis infection among health care workers in an infectious diseases hospital

目的了解传染病医院医务人员结核（TB）感染现况,探讨其感染TB的危险性及影响因素。方法对某传染病医院的全体医务工作者进行问卷调查和TB菌素纯蛋白衍化物（PPD）试验检测。结果该传染病医院全体职工TB感染发病率为48.18%。不同科室医务工作者的TB感染情况差异无统计学意义（P〉0.05）,不同工作年限、不同年龄、不同职称的医务工作者TB感染情况差异均有统计学意义（均P〈0.05）。文化程度、职称、目前居住情况、在结核感染门诊或病区的工作时间是TB感染的危险因素,其OR（95%CI）分别为1.70（1.03～2.80）、1.95（1.10～3.45）、1.84（1.03～3.28）、2.38（1.40～4.04）;个人防护是TB感染的保护因素[OR及OR95%CI为0.92（0.85～0.99）]。结论传染病医院的医务工作者是TB感染的高危人群,应加强自我防护意识,及早采取防护措施。

Objective To investigate the status of tuberculosis（TB）infection among health care workers（HCWs）in an infectious diseases hospital,and explore the risk and influencing factors of TB infection.Methods All HCWs in an infectious diseases hospital were surveyed through questionnaire and purified protein derivative（PPD）testing.Results Incidence of TB infection among all HCWs in this hospital was 48.18%.There was no significant difference in TB infection among HCWs in different departments（P〉0.05）.TB infection among HCWs of different working seniority,different ages,and different job titles were all significantly different（all P〈0.05）.Risk factors for TB infection were education level,job title,living condition,and working time in TB clinics or wards,OR（95%CI）were 1.70（1.03-2.80）,1.95（1.10-3.45）,1.84（1.03-3.28）,and 2.38（1.40-4.04）respectively;personal protection was a protective factor for TB infection（OR,0.92 [95% CI,0.85- 0.99]）.Conclusion HCWs in infectious diseases hospital are at high risk of TB infection,they should improve their self-protection consciousness,and take protective measures as early as possible.
