Abstract

Objective : The aim of the study was to determine the level of bacterial contamination of door handles/knobs of toilets and bathrooms at Daeyang Luke Hospital. Methods : Fomite can be described as a non-living object capable of carrying infectious organism and it is considered as one of the major source of spread of hospital acquired infection. In this study, door handles/knobs were swabbed with sterile swab stick moistened with sterile water. The content was evenly transferred to nutrient agar petric dish and then incubated for 24 hours at 37˚C. The study was done between the months of May to August 2016. Results : The results of the study showed that during the period of study there was 41.6% bacterial contamination with the female medical and surgical ward toilets being more contaminated as compared to staff toilets. Private room bathrooms were more contaminated during the period of study as compared to the staff room bathrooms that were less contaminated. Among the bacterial contaminant isolated and identified, Staphylococcus aureus had the highest prevalence followed by Escherichia coli , Pseudomonas aeruginosa , Citrobacter species and Klebsiella pneumoniae respectively. Conclusions : Therefore, from the study, it can be concluded that general public needs observe hand hygiene and use of quality disinfection procedures in order to reduce hospital acquired infection.

大阳路医院厕所和浴室门把手的细菌污染评估
目的:本研究的目的是确定大阳路医院厕所和浴室门把手/把手的细菌污染水平。方法:螨虫是一种能够携带感染性微生物的无生命物体,是医院获得性感染的主要传染源之一。在本研究中,门把手/把手用无菌棉签蘸无菌水擦拭。将内容物均匀转移到营养琼脂培养皿中,在37℃条件下孵育24小时。这项研究是在2016年5月至8月期间进行的。结果:调查期间细菌污染率为41.6%,内科、外科女病区厕所污染程度高于工作人员厕所。在研究期间,与污染较少的员工浴室相比,私人浴室的污染更严重。在分离鉴定的细菌污染物中,金黄色葡萄球菌的患病率最高,其次是大肠杆菌、铜绿假单胞菌、柠檬酸杆菌和肺炎克雷伯菌。结论:从本研究中可以得出结论,一般公众需要遵守手卫生和使用优质消毒程序,以减少医院获得性感染。
