Survey And Intervention Of Disinfection Hygiene Among Primary Medical Establishments Of Three Grades

Objective: To investigate the status of disinfection hygiene among three grades including county, town and village, and find the main impact factors. Then can we explore the feasible methods of improving antiseptic efficacy, decrease the possibility of hospital infection and eruption of infectious disease and provide scientific evidence for making decision.Method: Using both qualitative and quantitative research ways and stratified random sampling ,36 medical establishments of three grades were investigated in Zizhong county of Sichuan province, including 3 county hospitals, 8 public health centers of towns and 25 clinics of villages. The data regarding primary information of medical staff and general knowledge of disinfection hygiene and hospital infection was collected by structured questionnaire survey. The equipments of disinfection facilities and disinfectants, the utility and disposal of medical one-off article were respected and recorded by working staff.. the key indexes of disinfection efficacy were detected, including the contamination of objective surface, the hands of medical staff and using disinfectant, the status of air disinfection. After analyzing the collected data, we conduced a six-month-lasting intervention scheme focusing health education about hospital infection and antiseptic among medical staff of primary medical establishment using lectures and declaration, adding in some administerial intervention. Finally, detection results were used to evaluate the intervention efficacy.Results: 1, The whole diathesis of primary medical staff was low, such as lower educational background, lack of knowledge of hospital infection anddisinfection, the feeble consciousness of disinfection and sterility; The scores of medical genera! knowledge about infection and antiseptic hygiene was only 33.62 (full score is 100) ;The instruments and equipment were lack; The disinfectant equipping rate was low and the disinfectant structure improper.nly low effect; The popular rate of medical one-off article was lower than 100%. A few medical establishments disposed the used medical article. Certified rates of objective surface, hands, air, common disinfectant and the liquid for dipping in instruments were 64.59%, 63.13%, 62.34%, 91.47% and 70.45%, inspectively.2^ There is an obvious correlation between certified rate and educational background > The scores of medical general knowledge ^ age makeup > equipping rate of disinfectant and UV lighe respectively .3> All kinds of indexes had a well improvement at different extent. The scores of medical general knowledge about infection and antiseptic hygiene increased to 85.17 from 33.62; using rate of one-off medical article had reached 100% on the whole; Eligible rates of objective surface, the hands of medical staff, the air disinfection and in-use disinfectant had increased to 88.29%, 86.96%, 68.42% and 95.18% from 64.59%, 63.13%, 62.34% and 85.92%, respectively. There is almost no change in disinfection facilities after intervention except the clinics with equipping a few UV lights.Conclusion: At present, primary medical establishments have existed many questions, such as poor financial support, lower integrated diathesis, the consciousness of thinking highly of medical treatment and neglecting prevention, disordered management for infection control and disinfection efficacy, vulnerable supervision coming from governing department. All those questions have resulted in serious pollution, increased the possibility of infection and the eruption of infectious disease. The intervention, mainlyincluding health education, can obviously strengthen the medical staff's knowledge and consciousness of hospital infection and antiseptic hygiene which have improved disinfection efficacy and decreased the possibility of hospital infection and the eruption of the infectious diseases. However, the effect was limited, unless hardware setting of disinfection hygiene was improved and administrative supervision was strengthened.
