Objective To analyze the effect of inspection efficiency of large medical equipment on surgery-related time.Methods Data of surgical patients in a provincial top-three hospital in Anhui province from March to July 2023 were collected.A single-group intermittent time series analysis(ITSA)design was used to explore the changing trend of operation-related time before and after the improvement of inspection efficiency of large medical equipment,with preoperative waiting time,postoperative recovery time and hospital stay as the observational indicators.Results After the improvement of inspection efficiency of large medical equipment,the preoperative waiting time(β3=-0.010,P=0.048),postoperative recovery time(β3=-0.020,P＜0.001)and hospital stay(β3=-0.029,P＜0.001)were all decreased,and the differences were statistically significant.Con-clusion The improvement of inspection efficiency of large medical equipment can effectively reduce the operation related time,which can promote the utilization efficiency of medical resources and improve the medical experience of patients.
