ABSTRACT
ObjectiveTo analyze the disinfection quality of nursing institutions in Fengxian District， so as to provide evidence for improving disinfection work in nursing institutions. MethodsA total of 54 nursing institutions for the elderly in Fengxian District of Shanghai were selected as the monitoring sites during 2017‒2021. 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.
ABSTRACT
Objective To determine the current disinfection quality and understand existing problems in clinical institutions in Yangpu District， and provide scientific evidence for improving hospital infection control. Methods From 2018 to 2020， the specimens were collected from medical instruments， disinfectant in use， dialysis water in hemodialysis rooms， air， surface of objects， sterilization equipment， hands of medical staff， dental therapy water and sewage in clinical institutions in Yangpu District， and then examined for disinfection quality. Results A total of 1 420 samples were collected consecutively in 3 years， in which the total qualified rate was determined to be 88.52%. The qualified rates in secondary and tertiary hospitals， primary health centers， and private clinics were 94.86%， 90.22% and 75.74%， respectively， with a significant difference （χ2=95.01， P<0.01）. The qualified rates in sterilization equipment， air， and dialysis water were all 100.00%； in contrast， the rates in medical instruments， surface of objects， hands of medical staff， disinfectants in use， dental therapy water， and sewage were 98.28%， 97.63%， 95.05%， 93.39%， 54.71% and 50.00%， respectively. Conclusion Overall disinfection quality remains good in clinical institutions in Yangpu District of Shanghai， whereas the quality in private clinics is low. In addition， dental therapy water and hospital sewage might be susceptible to contamination， which warrants further improvement in the disinfection and monitoring.
ABSTRACT
Objective:To determine the disinfection effect in child care institutions in Qingpu District of Shanghai， and provide evidence for improving the disinfection quality and preventing and controlling infectious diseases. Methods:According to the monitoring program of disinfection quality in child care institutions in Shanghai， disinfection quality was monitored for 3 years. Results:A total of 979 samples were monitored in the consecutive three years， in which 895 samples were qualified with a total qualification rate of 91.42%. The qualification rate of air samples was 100.00%， while the rate of staff hand samples was the lowest， with an average of 79.60%. During 2016-2018， the difference among the annual qualification rates was statistically significant（χ2=23.809，P<0.05）， whereas it was not significant in the rates between public institutions and private ones （χ2=0.141，P>0.05）. Conclusion:The quality of preventive disinfection in child care institutions in Qingpu District is generally good， but the disinfection of tableware， surface of objects and staff needs to be further improved.
ABSTRACT
Objective To explore the feasibility of applying ATP bioluminescence technology to disinfection quality monitoring of the flexible endoscope.Methods Totally 30 flexible endoscopes used repeatedly from October 2014 to March 2015 were randomly selected,and had the disinfection quality monitored by ATP bioluminescence technology and bacterial culture method respectively.Parallel comparison was carried out to evaluate the feasibility of applying ATP bioluminescence technology to disinfection quality monitoring of the flexible endoscope.Results ATP bioluminescence technology showed that the qualification rate of the disinfection was 93.3％,and bacterial culture method found it was 96.7％.The two methods proved the outer surface of the endoscope had the disinfection acceptable while the biopsy hole and intracavity not.There was no significant correlation between the two methods while high consistency between the detection results by the two methods.Conclusion ATP bioluminescence technology can be used for preliminary screening in field,instant and daily monitoring of the medical flexible endoscope,which assists bacterial culture method in disinfection quality monitoring of the flexible endoscope.
ABSTRACT
Objective To understand the current status of disinfection and sterilization of medical institutions at all levels in 30 counties in Chongqing ,and to guide the work that medical institutions regulate and improve the quality of disinfection and steriliza‐tion ,and urge the relevant departments to strengthen the monitoring of disinfection quality of medical institutions .Methods Using field investigation and sampling inspection method ,the disinfection quality of medical institutions at all levels in 30 counties of Chongqing city was monitored and analyzed .Results From 30 districts and counties ,the medical institutions were sampled from 28 510 parts ,the overall average pass rate of 93 .3% .The qualified rate of medical institutions at all levels from high to low were as follows ,the village health room (96 .7% ) ,urban community medical institutions (96 .6% ) ,district level medical institutions (96 .1% ) ,individual clinic (90 .9% ) ,private hospitals (93 .7% ) and township (street) medical institutions (86 .5% ) .Different types of medical institutions got different qualified rate ,and the difference was statistically significant(χ2 =666 .84 ,P<0 .01) .Pro‐ject with the lowest qualified rate was radiation intensity of ultraviolet lamp(52 .8% ) ,secondly was indoor air (80 .4% ) and differ‐ent projects′qualified rate was significantly different(χ2 =1 706 .81 ,P<0 .01) .Conclusion Medical and health institutions at all levels′s disinfection quality were generally good ,but the village health room monitoring coverage ,ultraviolet light intensity and oth‐er individual monitoring projects need to be improved .
ABSTRACT

ABSTRACT
OBJECTIVE To investigate the impact of disinfection quality in surgical dressing room on the healing of wound with dressing exchanges in order to implement procedures to prevent nosocomial infection. METHODS A retrospective investigation was performed and cases of poor surgical wound healing from Jan 2006 to Dec 2007 were collected and analised. Effective measures were taken to enhance the management and surveillance in the dressing room. RESULTS After taking the prevention procedure,the passing rate of disinfection was increased. Before implementing the prevention procedure the passing rates of air,surface and finger cultured were 83.3%,83.3% and 75.0%,respectively,After taking the prevention procedure the passing rates of above were all 100.0%.The rate of poor wound healing decreased from 4.16% to 1.59%. CONCLUSIONS The disinfection quality of dressing room has direct effects on the wound healing. The management of dressing room disinfection should be emphasized to cut down the nosocomial infections of wound.
