Abstract: Objective To obtain accurate equipment operation information by analyzing the equipment log files intelligently, and to provide effective evidence for procurement decision-making by HB-HTA method.Methods The log files of CT equipment were collected, and the data of boot-up time, effective time, check-up number, and scan number were analyzed by using Pandas statistical software.Then Pearson analysis was used to analyze the correlation of scan number, boot-up efficiency, and total boot-up time.Results There was only a moderate correlation between the scan number and the total boot-up time, but a weak correlation between the utilization rate and the total boot-up time, and no correlation between the utilization rate and the total scan time.Conclusion Because of long service life and high maintenance rate, the utilization rate and load of the equipment are low.Therefore, when using HB-HTA for procurement demonstration, the Results can be used as evidence for investigation at the hospital level.
