综合性医院医护人员工作服细菌污染监测分析

目的了解综合性医院医护人员工作服染菌情况,并提出相应的管理措施。方法连续采集某院2012年5—10月呼吸内科、普通外科、妇科和儿科医务人员穿着清洁工作服后第1、3、7天的样本,共120件,360份标本,对医护人员工作服染菌量进行监测和比较分析。结果穿着不同时间段工作服染菌量比较,差异有统计学意义。工作服穿着时间越长,染菌量越大。护士与医生[(10.65±3.38)CFU/cm2 vs(7.68±2.99)CFU/cm2],手术科室与非手术科室[(10.43±4.12)CFU/cm2 vs(8.60±3.01)CFU/cm2]医务人员穿着工作服平均菌落数比较,差异均有统计学意义(U值分别为5.06、2.78,均P0.01),护士工作服的污染程度高于医生,手术科室高于非手术科室。工作服不同部位污染超标率比较,差异有统计学意义(χ2=33.12,P0.01);其中袖口污染最严重,其次是腹部和胸前,污染超标率分别是73.33%、58.33%、36.67%。结论应加强医务人员工作服清洗制度管理,建议医务人员工作服每周更换2次,污染严重的科室更换频率需加大。

Bacterial contamination on uniforms of health care workers in a general hospital

ObjectiveTo realize the bacterial contamination on uniforms of health care workers(HCWs)  in a general hospital,  and  put forward the corresponding management measures.   MethodsIn May October 2012, a total of 360 specimens of 120 uniforms of HCWs in departments of respiratory internal medicine, general surgery, gynecology, and pediatrics were taken on the first, third and seventh day of wearing, bacterial counts on uniforms were monitored, compared and analyzed.  ResultsBacterial counts of uniforms at different wearing time were statistically different. The longer time of uniforms were worn, the more bacteria could be detected. Bacterial contamination of nurses’ uniforms was more serious than doctors （［0.65±3.38］CFU/cm2  vs ［7.68±2.99］ CFU/cm2）, contamination of uniforms of HCWs in surgical departments was more serious than non surgical departments（［10.43±4.12 ］ CFU/cm2  vs ［8.60±3.01］ CFU/cm2) (U=5.06, 2.78,respectively, both P＜0.01）, over standard rate of different  sites of  HCWs’  uniforms were significantly different（χ2=33.12, P＜0.01）); over standard rates of bacteria on the cuffs, abdomen and chest sites was 73.33%, 58.33% and 36.67% respectively. ConclusionThe management of cleaning system of HCWs’ uniforms needs to be strengthened, the change cycle of uniforms is suggested twice a week, and the frequency needs to be increased in high contamination departments.
