Objective:To explore the application effect of data envelopment analysis(DEA)model in the safety and quality management of ventilators in intensive care units.Methods:Based on the Chanis-Cooper-Rhodes(CCR)dual model,by adding constraints,the input-oriented Bank-Carnes-Cooper(BCC)model was constructed to construct the DEA model.Among the 124 related items in the DEA model,20 high-level related items were identified to carry out ventilator quality control management related to clinical service efficiency.A total of 33 ventilators in clinical use in the intensive care unit(ICU)of Jiangsu Province Hospital from October 2021 to September 2023 were selected.Among them,the ventilators used from October 2021 to September 2022 were managed by traditional quality control management methods,and the ventilators used from October 2022 to September 2023 were managed by DEA model.The satisfaction scores,management quality scores and clinical efficiency scores of participants in ventilator use management were compared between the two management methods.Results:The satisfaction scores of medical staff,patients and equipment engineers for ventilator management using the DEA model management method were(96.68±2.25)points,(96.32±2.18)points and(95.66±2.54)points,respectively,which were higher than those of the traditional quality control management method,the difference was statistically significant(t=10.940,15.220,6.674,P＜0.05).The average scores of ventilator operation performance,inspection operation safety and timeliness using DEA model management method were(4.44±0.31)points,(4.53±0.37)points and(4.61±0.36)points,respectively,which were higher than those of the traditional quality control management method,the difference was statistically significant(t=12.692,14.979,17.025,P＜0.05).The average scores of ventilator work efficiency,ventilator response time efficiency and ventilator treatment efficiency using the DEA model management method were(4.49±0.32)points,(4.75±0.35)points and(4.68±0.32)points,respectively,which were all higher than those of the traditional quality control management method,with statistically significant differences(t=21.179,16.785,16.347,P＜0.05).Conclusion:The application of the DEA model in the management of ventilators in ICU can improve the efficiency of ventilator clinical service,improve the satisfaction of ventilator management personnel and the quality of ventilator management.
