目的了解重庆市医疗机构医务人员清洗消毒后的手卫生状况,比较不同科室、机构间存在的差异。方法采用分层抽样的方法,于2012-2014年对重庆市28家医疗机构医务人员手进行清洗消毒后采样,并就菌落数和合格率进行统计学分析。结果三年共计采样935人次,整体合格率为99.57%。不同科室、环境、医院间菌落数差异均有统计学意义(P<0.01),其中外科手术室和Ⅰ类环境菌落中位数均为0(0,0)cfu/cm2低于其他分组;私营医院菌落中位数为1(0,5)cfu/cm2高于其他类型医院,差异均有统计学意义(P<0.01)。结论 2012-2014年监测的28家医疗机构医务人员消毒后手卫生效果较好,但仍应注意部分医院的治疗室、口腔科及私营医院的医务人员手卫生质量,在洗手方法和院感控制上加强管理。

The results of a total of 935 sampling three years, the overall pass rate was 99.57%. There were significant differences in the number of colonies between different departments, environments and hospitals (P <0.01), and the median of surgical operating rooms and environmental colony type Ⅰ were 0 (0,0) cfu / cm2, lower than other subgroups The hospital colonies median 1 (0,5) cfu / cm2 higher than other types of hospitals, the differences were statistically significant (P <0.01). Conclusions Hand hygiene in 28 medical institutions monitored in 2012-2014 is better after disinfection, but hand hygiene and quality of hand hygiene and hospital control should be paid attention to in the treatment rooms, the dentists and the private hospitals in some hospitals.
