一起医院内由肺炎支原体引起的肺炎暴发调查

Investigation of a mycoplasma pneumoniae caused outbreak in a hospital

摘要: 2014年10月江苏省苏州市某医院多名护士出现发热、咳嗽、肺部影像改变。现场调查共发现15例病例，血清检测6例病例支原体阳性。回顾性队列研究显示，值夜班（RR＝11.7，95%CI：1.1~154.1）、护班（RR＝44.0，95%CI：2.6~2 120.6）是本次医护人员感染的可能危险因素。本次事件是医院内支原体肺炎暴发，原因可能是护士在护理疑似患者过程中感染。建议医护人员加强个人防护。

Abstract: In October, 2014, fever, cough and pneumonia developed in some nurses in the nephrology department of a hospital in Suzhou, Jiangsu province. A total of 15 patients were identified, among them 6 were mycoplasma pneumoniae positive. Retrospective cohort analysis indicated that night shift (RR=11.7, 95% CI: 1.1-154.1), nursing shift (RR=44.0, 95% CI: 2.6-2 120.6) were the risk factors for the mycoplasma pneumonia infection in this outbreak. The outbreak was very likely to be caused by close contact with suspected hospitalized patients. It is necessary to improve the awareness of self-protection in medical staff.
