Objective To understand the effectiveness of medical disinfection in a hospital in Baoshan District of Shanghai and to discuss the effect of improvement measures of disinfection quality.
Methods Based on the Disinfection Technology Standards (former Ministry of Health, 2002 version), uneven disinfected samples were collected in the hospital once a month to evaluate disinfection effectiveness.
Results The total qualified rate of the disinfected samples was 97.94% in the hospital. The qualified rates of air, surface, medical staff's hands, disinfectants in use, and sterile items were 97.22%, 98.00%, 98.26%, 98.15%, and 98.33%, respectively. Significant differences were found in the qualified rates of air, surface, and sterile items among different years (P < 0.05). The disinfection qualified rates of 2011 and 2012 were significantly higher than that in 2010 (χ2=18.337, P < 0.01; χ2=16.326, P < 0.01).
Conclusion Strengthened hospital infection management, implementation of disinfection related regulations, disinfection training, and awareness of disinfection and sterilization in medical staff are required to improve the disinfection quality in medical institutions.
