医务人员手带菌状况调查与对策

Investigation and Countermeasures to the Germ-Carrying Hands of Medical Staffs

目的调查不同情况下医务人员手部带菌状况,并研究相应对策。方法随机抽查本院168名工作中的临床医护人员,调查洗手前后手部带菌状况,并对菌株进行分离鉴定和耐药性分析。结果洗手前手细菌总数平均41.064cfu/cm2,洗手后手合格率84.8%。医生手细菌总数洗手前后均较护士多。"无菌操作"组手卫生状况较好。手部检出细菌主要是葡萄球菌、枯草芽孢杆菌和非发酵革兰氏阴性杆菌,医务人员手耐药菌携带率高。结论医务人员手卫生状况不容乐观,应加强医务人员手卫生培训与监督,提高医务人员手卫生合格率。

Objective To investigate the germ-carrying hands in various states of medical staffs and search for corresponding countermeasures. Method 168 medical staffs were sampled randomly. Samples were collected for identification and drug resistant analysis of the germs before and after hand washing. Results Before hand washing the general bacterial population were 41.064 cfu/cm^2, while after hand washing 84% medical staffs were up to standard. The bacterial counts of the hands of doctors were higher than that of nurses before and after hand washing. In the sterile operation group, the hand hygiene was better. The bacteria identified were mainly staphylococci, Bacillus subtilis and nonfermenters Gram-Negative bacillus. Drug-resistant strains were found frequently in medical staffs. Conclusion The hand hygiene of medical staffs was not optimistic. We should reinforce training and monitor on hand hygiene to improve the hand hygiene of medical staffs.
