The samples from indoor air， surface of objects， tableware and hands of staff were collected for bacteriological testing， and then evaluated for the quality of sanitary disinfection.ResultsFrom 2017 to 2021， the annual qualified rate of disinfection quality in the nursing institutions was 84.85%‒100.00%， and there was a significant difference of the monitoring samples among different years （χ2=51.73，P<0.01）. A statistically significant difference was observed among the different types of nursing homes （χ2=25.83，P<0.01）. The qualified rate of indoor air was 100.00%， and the qualified rate of surface of environmental， surface of tableware and hands of staff were 93.21%， 92.59% and 86.73%， respectively. The qualified rates of disinfection of different types of samples were statistically significant （χ2=53. 803，P<0. 001）. The qualified rate of different types of staff hands was from 79.17% to 92.71%， and the qualified rate of cleaners and care-givers were lower than the healthcare practitioners （χ2=6.53，P<0.05）. The lowest test pass rate was surface of faucets， which was 83.33% （χ2=23.85，P<0.01）.ConclusionThe quality of disinfection in the nursing institutions for elderly in Fengxian District needs to be improved， and it is necessary to make further efforts to strengthen the hand hygiene of staff， the disinfection quality of tableware and surface of objects.
