ABSTRACT

Objective:To study the application value of refined centralized management combined with scientific preventive maintenance in the standardized management of clinical ventilators.Methods:The ventilator failure information wad collected,a ventilator information management database was established,the refined and centralized management and scientific preventive maintenance measures for ventilators was developed in terms of planning,implementing,and updating the ventilator management system as well as training and assessment.119 ventilators in clinical use in People's Hospital of the Xinjiang Uygur Autonomous Region from 2021 to 2022 were selected,the conventional management mode(referred to as conventional mode,50 units)and the refined centralized management combined with scientific preventive maintenance mode(referred to as joint mode,69 units)were adopted respectively for management.The maintenance status of ventilators in the two modes and the total amount of work in 2021 and 2022 were compared.Results:There were 85 ventilator failures in 2021 and 58 ventilator failures in 2022 in conventional mode.34 ventilator failures in 2021 and 44 ventilator failures in 2022 in joint mode.The number of failures,maintenance time and satisfaction of clinical department with the ventilators of the joint mode in 2021 were(3.25±1.06)times/month,(12.57±10.31)days and(91.50±1.73)% respectively,the number of failures and maintenance time were less than those of conventional mode,satisfaction of clinical department was higher than that of the conventional mode,the difference was statistically significant(t=14.458,2.501,2.563,P<0.05).The number of failures of ventilators of joint mode in 2022 was(3.08±2.02)times/month,which was less than that of conventional mode,the difference was statistically significant(t=4.655,P<0.05).The number of failures,number of times to contact the equipment department,consumable costs,adverse events,and number of terminal disinfections for 119 ventilators of the two modes in 2021 were(10.25±2.34)times/month,(16.75±6.54)times/month,and CNY(44,000±49,300)/month,(2.49±0.92)pieces/month and(382.58±83.67)times/month,which were higher than those in 2022,the equipment completeness rate and frequency of clinical training were(88.27±1.29)% and(3.42±1.51)times/month,respectively,which were lower than those of 2022,the difference was statistically significant(t=5.124,6.103,4.099,7.884,1.980,5.607,3.564,P<0.05).Conclusion:Refined centralized management combined with scientific preventive maintenance can effectively reduce the number of ventilator failures,maintenance time and costs,etc.,and improve the quality of standardized management of clinical ventilators.
