Objective To understand the disinfection effect of municipal medical institutions in Ningbo and to provide a basis for effective prevention and control of nosocomial infections. Methods On-site sampling and microbiological detection methods were used to monitor and analyze the disinfection quality of 10 projects in Ningbo municipal medical institutions. The monitoring data were analyzed by Excel2007 and SPSS 19.0. Results A total of 2 120 samples (1 897 samples) were tested during 2011-2015, with a pass rate of 89.48%. The pass rate showed an upward trend in 5 years (P <0.05). Among the different test items, the lowest pass rate was 80.05%, disinfectant in use and pressure steam sterilization were all qualified; different sizes of medical institutions pass rate was no significant difference (P> 0.05), of which specialist and small general hospital disinfection rate of the surface of the object higher than Large general hospital (P <0.05). The total qualified rate of disinfection before and after the standard change was statistically significant (P <0.05). Conclusion The quality of disinfection effect of Ningbo municipal medical institutions is generally good, medical staff hand hygiene needs to be further improved.
