Research on the value of refined centralized management combined with scientific preventive maintenance in the standardized management of clinical ventilators / 中国医学装备

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.

Analysis of medical devices maintenance cost and optimization proposal / 中华医院管理杂志

Objective To learn the present hospital expenditures of medical devices maintenance for improvement recommendations. Methods An investigation was made to the clinical engineering sections of 33 hospitals in 2018, including 11 Beijing hospitals and 22 Zhejiang hospitals. Indicator values of maintenance expenditure were obtained, and the data were subject to descriptive statistics. Results The mean of beds of these hospitals was 1514. 13 ± 710. 99, that of medical devices was 8120. 90 ± 6488. 63, that of original value of these devices was 843 ± 496 million yuan, and that of maintenance cost was 17. 35 ± 11. 92 million yuan. This indicated the cost of service ratio as 2. 02％. Conclusions Training of engineers should be strengthened at the sections, for more in-house maintenance. Informationization should be enhanced for precision maintenance. Multi-channel maintenance model should be introduced to further lower the costs.

Analysis of Key Factors Affecting Maintenance Cost of Large-Scale Medical Equipment / 医疗卫生装备

Objective To explore the key factors which affect maintenance cost of large-scale medical equipment. Methods The basic factors which affect maintenance cost of medical imagining equipment were summarized. The relationships of them are analyzed and then an interpretative structure mode of each factor was set. Additionally, the multiple relationship and controllability between each factor were also analyzed and the judging standard of key factors was set. Results The maintenance policy and mode were the key factors which affect maintenance cost of medical imagining equipment. Conclusion High quality maintenance for equipment condition and scientific optimization of the maintenance policy are necessary to fundamentally reduce the maintenance cost of large-scale medical equipment.

Fault Statistics and Maintenance Cost Analysis About Using Digital Gastrointestinal Machine of SIREGRAPH CF / 医疗卫生装备

Statistically analyses SIEMENS SIREGRAPH CF digital gastrointestinal machine the breakdown and maintenance cost which appears in the radialized practice by the note for the fault maintenance,making fault statistics by Excel,discusses in the emission practice,how displays the equipment benefit fully and saves the service cost possibly,and the results of digital gastrointetinal machine's fault frequency of system is got.to discuss the reasonality of this kind of equipment voluntarily services in second level of hospital.[Chinese Medical Equipment Journal,2008,29(2):78-79]
