天津市部分医院重症监护室医务人员革兰阴性菌携带状况分析

Analysis on the carrying status of Gram-negative bacteria in ICU medical staff in some hospitals in Tianjin

目的了解天津医院重症监护室(ICU)医务人员自身携带革兰阴性菌状况,为防控医务人员病原菌携带率提供依据。方法通过细菌分离鉴定技术,对天津市部分医院ICU医务人员连续11年鼻前庭和手部采样标本进行检测与分析。结果11年共对1541名人员(含134名非医疗岗位人员)鼻前庭或手采样标本3082份。从284人的标本中检出革兰阴性菌342株,其中多耐药菌为144株,占42.11%。共发现有134名医务人员存在革兰阴性菌定植,定植率为9.52%。结论天津市医院ICU医务人员中革兰阴性菌携带率和定植率均比较高,应当加强医务人员细菌携带和定植监测,实施必要的控制措施。

Objective To understand the carring status of Gram-negative bacteria in ICU medical staff in Tianjin hospitals,and to provide evidence for prevention and control of the carrying rate of medical staff.Methods Through the separation and identification technology of bacteria,the ICU medical staff of some hospitals in Tianjin were tested and analyzed for 11 consecutive years of nasal vestibule and hand samples.Results In 11 years,a total of 3082 samples of nasal vestibules or hand samples were collected from 1541 medical staff(including 134 non-medical staff).Gram-negative bacteria were detected from 284 samples,and 342 strains of Gram-negative bacteria were detected in total.The number of multi-drug resistant bacteria were 144,accounting for 42.11%.A total of 134 medical staff were found to have Gram-negative bacteria colonization,with a colonization rate of 9.52%.Conclusion The carrying rate and colonization rate of Gram-negative bacteria in ICU medical staff in Tianjin hospital are relatively higher.It is necessary to strengthen the monitoring of bacterial carrying and colonization in medical staff and implement necessary control measures.
