Abstract:
Objective:To analyze the relevant influence factors and the practical effects of improvement strategies of ultrasonic cleaning effect on medical apparatuses of central sterile supply department(CSSD)of hospital.Methods:The medical apparatuses were cleaned by ultrasound in hospital between March and June 2022 were selected.The influencing factors of cleaning effect of medical apparatuses were analyzed by Logistic regression model,and the corresponding improvement strategies were formulated according to the above factors.The medical apparatuses during the period from July to September 2022 after the improvement strategies were implemented were selected to compare the cleaning effects between before and after implemented improvement strategies.Results:Before the improvement strategies were implemented,the cleaning qualities of 41 times were not quality in the cleaning of 465 times for medical apparatuses,and the cleaning qualities of 424 times were quality,which qualified rate of cleaning was 91.18%.The results of Logistic regression analysis showed that whether the normalization of pre-washing,water quality,cleaning medium and cleaning conditions were qualified were independent influence factors of ultrasonic cleaning effect of CCSD medical apparatuses(OR=6.673,OR=5.140,OR=3.983,OR=5.023,P<0.05).After the improvement strategy was implemented,there was not unqualified cleaning in the cleanings of 465 times of medical apparatuses,and the qualified rate of cleaning was 100%,which was higher than that before improvement strategy was implemented(x2=42.891,P<0.001).Conclusion:The independent influence factors of the ultrasonic cleaning effect of CCSD medical apparatuses were respectively the normalization of pre-washing,water quality,cleaning medium and cleaning conditions.The formulated improvement measures based on the above factors can significant improve the cleaning effect.
