Fluorescence labeling method for evaluating the efficacy of hospital environment cleaning / 中国感染控制杂志

ABSTRACT

Objective To evaluate the effectiveness of hospital environmental cleaning practice by fluorescence labeling method.Methods From January to February 2015,312 ward rooms in 7 hospitals were chosen,high touch object surface were labeled with fluorescence,after object surface being cleaned by cleaners,clearance rates of fluorescence labeling were calculated (as baseline survey data),training and on-site guidance for cleaners were performed(intervention measures),fluorescence labeling clearance effect before and after intervention was compared.Results A total of 110 ward rooms were performed baseline survey,the fluorescence labeling clearance rate of 2 856 touched clean surface was only 50.81％,the quantitative evaluation value was 45.70;after intervention,202 rooms were surveyed,fluorescence labeling clearance rate of 3 992 touched clean surface enhanced to 79.23 ％,the quantitative evaluation value was 76.30;there was significant difference in fluorescence labeling clearance rate between before and after intervention (x2 =612.14,P＜0.05).In the baseline survey,the clearance rates of fluorescence labeling on touched surface of medical instruments,hospital beds,and toilets were 46.07％,37.80％,and 25.20％ respectively;after intervention,the clearance rates were 80.59％,75.90％,and 51.70％,respectively.After intervention,fluorescence labeling clearance rates of beepers,toilet seat covers,toilet electrical switches,and chairs were low,the clearance rates of these touched surface in baseline survey were＜ 30％,after intervention were 47.03 ％-68.32％;the clearance rates of other high touch surface were all＞75 ％.Conclusion Fluorescence labeling method can directly reflect the operation quality of cleaners,and improve the cleanliness of ward environment,it is a simple,inexpensive and objective globally popular method for evaluating hospital environment cleanliness.
