摘要
目的 调查某医院重症监护病房(ICU)高频接触物体表面污染与工作人员手卫生情况,并评价采取干预措施的效果.方法 2023年3-9月采集该医院ICU专用吊带、床单元织物等高频接触物体表面和工作人员手卫生样本,比较培训、现场技术指导和督导考核等干预措施实施前后样本卫生或消毒合格率以及病原菌检出率.结果 干预前采样123份,干预后采样156份.干预后,专用吊带平均卫生合格率由73.2%提高至93.3%,床单元织物卫生合格率由70.8%提高至96.7%;床头柜、床栏和床旁仪器的消毒合格率分别由31.3%和18.2%提高至72.2%和66.7%;专用吊带和床单元织物病原菌检出率分别为40.0%和33.3%,低于干预前的89.3%和87.5%(P<0.05);干预前后工作人员手卫生合格率差异无统计学意义(87.5%vs 92.6%;P=0.621).结论 通过培训、现场技术指导、督导考核等措施可有效降低医院ICU污染.
Abstract
Objective To investigate the surface contamination of high-frequency contact objects and hand hygiene of staff in a hospital ICU,and to evaluate the effect of intervention measures.Methods The surface samples of high frequency contact objects such as slings and sheet fabrics in ICU and samples of hand hygiene of staff were collected from March to September 2023.The qualified rate of sample hygiene or disinfection of pathogenic bacteria were compared before and after taking intervention measures such as training,on-site technical guidance and supervision and assessment.Results There were 123 samples before intervention and 156 samples after intervention.After the intervention,the average sanitary qualification rate of special sling increased from 73.2%to 93.3%,and the sanitary qualification rate of sheet fabrics increased from 70.8%to 96.7%.The disinfection qualification rate of bedside tables and bed guardrails had increased from 31.3%to 72.2%,and that rate of bedside instrument disinfection increased from 18.2%to 66.7%;The detection rate of special sling and sheet fabric was 40.0%and 33.3%respectively,lower than 89.3%and 87.5%before intervention(P<0.05).There was no significant difference in the qualified rate of staff hand hygiene before and after the intervention(87.5%vs 92.6%;P=0.621).Conclusion The contamination in the ICU can be effectively reduced by taking measures such as training,on-site technical guidance,supervision and assessment and other measures.
