不同手卫生方式及干手措施对手卫生效果的影响

Effect of different hand hygiene methods and hand drying measures on hand hygiene

目的调查不同手卫生方式和干手措施对手卫生效果的影响,提高手卫生质量。方法选择河南省8所哨点医院不同科室的医务人员为调查对象。观察医护人员手卫生方式及干手措施,比较不同手卫生方式及干手措施的手卫生微生物检测合格率。结果共调查医护人员699人次,执行手卫生者572人次,手卫生依从率为81.83%。洗手是最常用的手卫生措施,占39.34%。监测结果显示,采用速干手消毒剂进行卫生手消毒的合格率最高,为97.92%,不同手卫生方式的手卫生合格率比较,差异有统计学意义(χ^2=20.203,P<0.001)。干手措施以自然风干为主(79.37%),一次性纸巾、自动风干机和其他方式所占比率分别为14.69%、1.75%和4.20%。不同干手措施后的手卫生合格率比较,差异有统计学意义(P=0.013)。洗手组和先洗手后卫生手消毒组别中,均为使用一次性纸巾干手后的合格率最高,分别为80.70%、96.30%。结论涂抹速干手消毒剂进行卫生手消毒效果可靠,最佳干手措施应首选一次性干手纸巾。

Objective To investigate the effect of different hand hygiene(HH)methods and hand drying measures on HH,and improve the quality of HH.Methods Health care workers(HCWs)in different departments of eight hospitals in Henan Province were selected as the surveyed subjects.HH methods and hand drying measures were observed,qualified rates of microbial detection of HH among different HH methods and hand drying measures were compared.Results A total of 699 HCWs were surveyed,572 times of HH were performed,compliance rate of HH was 81.83%.Hand washing is the most common HH measure,accounting for 39.34%.The qualified rate of HH by alcohol-based hand rub was 97.92%,qualified rate of HH among different HH methods was statistically significant(χ^2=20.203,P<0.001).The main HH measures was natural air drying(79.37%),proportion of drying by disposable tissue,automatic air dryer and other methods were 14.69%,1.75%and 4.20%respectively.There was significant difference in qualified rates of HH after different hand drying measures(P=0.013).In hand washing group and hand disinfection after hand washing group,the qualified rate of using disposable tissue to dry hands was the highest,accounting for 80.70%and 96.30%respectively.Conclusion Application of alcohol-based hand rub is reliable for hand disinfection,the best way of hand drying is to use disposable tissue.
