摘要： 目的 通过智能化地分析设备日志文件,从日志中获得更准确的设备运行信息,可以为用HB-HTA方法进行采购决策提供有效的证据。方法 收集CT设备的日志文件,采用Pandas统计软件对开机时长、有效时长、检查数、扫描数等数据进行分析,然后使用Pearson分析方法对扫描数量、开机使用效率、总开机时间等指标进行相关性分析。结果 扫描数量和总开机时间只有中等程度相关;使用率和总开机时间呈弱相关,使用率和总扫描时间不相关。结论 由于该设备使用年限较长、维修率较高,导致其使用率较低,无法达到负荷。因此在使用HB-HTA进行采购论证时,可以将其结果作为医院层面调研的依据。

关键词: 日志分析, 医院卫生技术评估, 使用率, 采购论证

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.

Key words: Log analysis, Hospital-based health technology assessment, Utilization rate, Procurement demonstration
