The comparison between disinfection effectiveness in 2013 and 2014Total qualified rate of disinfection status in private clinics was 89.48% and 93.12%, respectively in 2013 and 2014. Qualified rate of medical staffs’ hand hygiene was 82.35% and 84.62%, respectively. There was no significant different between them(P > 0.05). The disinfection effectiveness of clinic countertops in 2014 was increased in comparison with 2013(qualified rate: 99.21% vs 92.26%, P < 0.01). Disinfection status in internal medicine clinics and clinics not carrying out invasive treatments improved obviously. Qualified rate of UV light irradiance was 83.19% and 90.32% in 2013 and 2014, respectively. The difference was statistically significant(P < 0.05). Among all clinics of different type, dental clinics were most significantly improved. In 2013 and 2014, the average pass rate for sterilization of medical devices was 98.85% and 98.99%, respectively. There was not significant different between them.Conclusions:The total disinfection status of private clinics in Gusu district of Suzhou City was acceptable, however, medical staffs’ hand hygiene and the qualified rate of ultraviolet light were not satisfied. The training of medical staffs’ hand hygiene and the routine use of ultraviolet light disinfection should be strengthened. The disinfection effectiveness in dental clinics, internal medicine clinics and other clinics carrying out invasive treatments was acceptable, while the status in private clinics not carrying out invasive treatments was unsatisfied due to ignoring disinfection and isolation measures. Medical staffs’ hand hygiene in private clinics was not significantly improved in 2014. However, the disinfection status of clinics countertops was improved, especially in internal medicine clinics. And the UV light irradiance was also significantly improved in 2014 in private clinics, especially in dental clinics. The disinfection status of private clinics was effectively enhanced by two consecutive years of monitoring and reduced the risk of iatrogenic infection. |
