Analysis on Disinfection Effect of Surface of Objects in ICU Environment

Objectives To explore the environmental sanitation and the quality of disinfection on the surface of objects in the intensive care unit(ICU) of hospital, and provide evidence for control and prevention of hospital acquired infection.

Methods Conducting a target monitoring on the disinfection effect of the surface of objects frequently touched by the hand of ICU medical staffs during May 2014 to January 2015. The objects monitored were hospital bed units and the surface of medical public areas. The qualified rate of disinfection and the positive rate of target pathogens were analyzed by the SPSS 19.0.

Results The overall qualified rate was 69.08% (219/317), the qualified rate for hospital units was 66.48% and that for the environmental surface of medical public regions was 72.46%. No statistical difference was observed between them. In all kinds of specimens collected for monitoring targeted pathogens (467), 66 strains of bowman's acinetobacter were examined, the positive rate was 14.13%, and they were all generic pan-drug resistant acinetobacter baumannii.

Conclusions The overall qualified rate for environment surface of ICU was low, the quality of daily cleaning and disinfection remained to be improved. The sanitary management of objects frequently touched by the hand of medical staffs should be strengthened. Standardized operational procedures for environmental surface cleaning and disinfection in ICU should be developed.
