Research On Disinfection Quality Monitoring And Intervention Effect At Medical Institutions In Ningxia Hui Autonomous Region

Objective:1.According to statistical analysis of the data regarding disinfection quality monitoring at Ningxia medical institutions between 2011 and 2016,the situation of cleaning,disinfection and sterilization quality was obtained.The data will provide a basis for revision of relevant policies,regulations and standards.2.Intervention measures were carried out to compare the differences of disinfection quality before and after intervention at several medical institutions in Yinchuan,Ningxia Hui Autonomous Region.Deficiency of disinfection work was found,and effective measures were implemented to strengthen infection management of these hospitals.3.Hand hygiene was investigated and that was a pivotal factor for infection control at hospital.Thus the quality and influencing factors of hand hygiene disinfection were evaluated to find out the key groups and appropriate methods of decontamination,which would provide a reference for better control of hand hygiene at hospital.Methods:1.Monitoring data at centers of disease control of different grades were collected between 2011 and 2016.These monitoring data were entered,summarized,and analyzed.2.Three,two,one grades of medical institutions were randomly selected in the city of Yinchuan.The medical staff were chosen as intervention.Then,comprehensive intervention measures were conducted regarding publicity training,on-site technical guidance,leadership discussion and outcome feedback.Questionnaire survey and disinfection quality monitoring were carried out,evaluated and analyzed to confirm whether disinfection situation were improved before and after the intervention.3.The samples were randomly selected,including three,two,one grades of medical institutions in Yinchuan.The medical staffs were regarded as object of the study.Through the questionnaire survey and hand hygiene monitoring,the knowledge of hand hygiene was obtained,and disinfection effectiveness of hospitals at different grades,positions and handwashing way was evaluated.Results:1.A total of 71765 samples were chosen at Ningxia medical institutions between 2011 and 2016.The results showed that the total qualification rate was 92.32%.The qualification rate of disinfection quality monitoring was statistically significant between each year(χ2 =572.21,P<0.001),and the qualification rate between medical institutions of different grades was statistically significant(χ2=1182.16,P<0.001).Of that,ultraviolet light(89.71%)and indoor air(83.91%)were shown a lower qualification rate.2.Significant difference was found regarding average score of questionnaires between before and after intervention was(t=65.13,P<0.001).The qualification rate of the operating room air(χ2=11.35,P<0.001),environmental objects(P<0.05),hand hygiene(χ2=22.07,P<0.001),medical device(χ2=13.63,P<0.001),medical water(χ2=4.90,P<0.05)between before and after the intervention was statistically significant.No significant difference was observed with respect to qualification rate of surgical hand-washing(P>0.05),endoscopy(χ2=2.27,P>0.05)between before and after intervention.3.The score of hand hygiene knowledge at different grades of hospital(F=11.99,P<0.001)and department(F=4.42,P<0.05)was statistically significant,The overall qualification rate of hand hygiene was 67.35%.The qualification rate of hand hygiene at different grades of medical institutions(χ2=19.33,P<0.05),doctors and nurses(χ2 = 22.46,P<0.05),four different handwashing ways(χ2 = 37.57,P<0.05)was statistically significant.Conclusion:1.The disinfection quality was insufficient below one grade of medical institutions and that should be focused in the future.Centers of disease control should strengthen supervision and inspection to improve the situation of disinfection.2.UV light and indoor air were insufficient concerning the disinfection work of medical institutions in Ningxia Hui Autonomous Region.Therefore,hospital disinfection management,regular monitoring,disinfection methods,disinfection equipment should be strengthened and improved.3.Comprehensive intervention measures,including publicity training,on-site technical guidance,leadership discussion and outcome feedback,should be conducted.Through strengthening the disinfection knowledge of medical staff and hospital infection management,the disinfection,sterilization system and quality of disinfection qualification rate would be improved.4.As a simple,fast,powerful handwashing way,hand disinfectant could be adopted as a fast hand disinfectant instead of soap or hand sanitizer,when no visible pollution was found in the hand.
