Objective:To analyze application effect of trend analysis for safe risk in management and control for infection of medical devices,so as to optimize the management path for medical devices.Methods:Focusing on the main factors affecting the safety risks of medical devices,the least squares method of linear regression was applied for trend analysis to optimize the device management path and strengthen management.A total of 70 clinically used medical devices in the First Affiliated Hospital of Xi'an Jiaotong University from January to December 2024 were selected.These devices were managed using two models:the conventional management model and the trend analysis management model,with 35 devices under each model.The infection risk rate of medical equipment and the equipment management quality score were compared between the two management models.Additionally,160 patients managed under the two models(80 patients per model)were included to compare the patient infection rate.Results:In the 450 diagnostic and treated records of sampling inspection and consultation for medical devices from treatment equipment,diagnosis equipment,auxiliary imaging equipment and surgical equipment,the rate of infectious risk of using management mode with trend analysis were respectively 1.78%(8/450),2.22%(10/450),2.22%(10/450)and 2.44%(11/450),all of which were significantly lower than these of using conventional management mode,and the differences were significant(x2=9.904,8.902,10.465,10.770,P＜0.05).The scores of cleaning quality,the quality of disinfection and sterilization,the quality of distribution,and the retrieving quality of the management mode with trend analysis for medical devices were significantly higher than those of the conventional management mode,and the differences were statistically significant(t=15.889,13.172,15.872,17.399,P＜0.05).The infection rate of patients in the trend analysis management mode was 6.25%(5/80),which was significantly lower than that in the conventional management mode[22.50(18/80)],and the difference was statistically significant(x2=11.006,P＜0.05).Conclusion:The trend analysis for safe risk can analyze the risk factors in use and operation for medical devices from multiple perspectives,and mining main factors and conduct intervention for the devices,and reduce the incidence of safe risks of medical devices and the patients'infection rate,and improve the quality of clinical services.
