The quality of environmental hygiene in hospitals is under increasing scrutiny from both healthcare providers and consumers because the prevalence of serious infections due to multidrug-resistant pathogens has reached alarming levels. On the basis of the results from a small number of hospitals, we undertook a study to evaluate the thoroughness of disinfection and cleaning in the patient's immediate environment and to identify opportunities for improvement in a diverse group of acute care hospitals.
Prospective multicenter study to evaluate the thoroughness of terminal room cleaning in hospitals using a novel targeting method to mimic the surface contamination of objects in the patient's immediate environment.
Twenty-three acute care hospitals.
The overall thoroughness of terminal cleaning, expressed as a percentage of surfaces evaluated, was 49% (range for all 23 hospitals, 35%-81%). Despite the tight clustering of overall cleaning rates in 21 of the hospitals, there was marked variation within object categories, which was particularly notable with respect to the cleaning of toilet handholds, bedpan cleaners, light switches, and door knobs (mean cleaning rates, less than 30%; institutional ranges, 0%-90%). Sinks, toilet seats, and tray tables, in contrast, were consistently relatively well cleaned (mean cleaning rates, over 75%). Patient telephones, nurse call devices, and bedside rails were inconsistently cleaned.
We identified significant opportunities in all participating hospitals to improve the cleaning of frequently touched objects in the patient's immediate environment. The information obtained from such assessments can be used to develop focused administrative and educational interventions that incorporate ongoing feedback to the environmental services staff, to improve cleaning and disinfection practices in healthcare institutions.
医院环境卫生质量受到医疗服务提供者和消费者越来越多的审视,因为多重耐药病原体导致的严重感染患病率已达到惊人水平。基于少数医院的结果,我们开展了一项研究,以评估患者直接环境中消毒和清洁的彻底程度,并确定不同类型急性护理医院中可改进之处。
采用前瞻性多中心研究,运用一种新颖的靶向方法模拟患者直接环境中物体的表面污染,以评估医院终末病房清洁的彻底程度。
23家急性护理医院。
以评估表面的百分比表示的终末清洁总体彻底程度为49%(所有23家医院的范围为35%-81%)。尽管21家医院的总体清洁率紧密聚集,但不同物体类别之间存在显著差异,在马桶把手、便盆清洁器、电灯开关和门把手的清洁方面尤为明显(平均清洁率低于30%;各机构范围为0%-90%)。相比之下,水槽、马桶座圈和托盘桌的清洁情况一直相对较好(平均清洁率超过75%)。患者电话、护士呼叫设备和床边栏杆的清洁情况不一。
我们发现在所有参与研究的医院中,均存在显著机会来改善患者直接环境中频繁接触物体的清洁状况。从这类评估中获得的信息可用于制定有针对性的行政和教育干预措施,其中纳入对环境服务人员的持续反馈,以改善医疗机构的清洁和消毒做法。
