OBJECTIVE.我们研究了从传统胶片到硬拷贝计算机X线摄影的变化以及随后在图像存档和通信系统（PACS）工作站上移动到软拷贝图像对放射科医生报告时间的影响。进行了前后对照的研究设计。数据收集了四次：两次与传统胶片有关，一次与硬拷贝计算机X线摄影有关，一次与软拷贝PACS图像有关。数据收集是通过独立卫生服务研究人员直接观察放射学报告会议进行的。收集了报告时间、查看的图像细节、放射科医生的特征和中断的细节等数据。为了控制前后比较中的潜在偏倚，使用普通最小二乘多元回归分析。主要比较的是PACS报告和计算机X线摄影硬拷贝报告，因为除了引入PACS之外，在这两轮数据收集之间的报告流程组织方面没有发现任何变化。共收集了5568份报告观察结果的数据。PACS数据收集期的报告时间与计算机X线摄影硬拷贝期的报告时间无显著差异（p = 0.32）。PACS的报告与显著更多（p < .01）的历史图像（即，在先前检查中获得的同一患者的图像）被查看。报告时间没有因PACS的引入而延长。当使用PACS时，更多的历史图像被查看，这一发现表明PACS在报告实践中带来了积极的变化。
OBJECTIVE. We investigated the impact on radiologist reporting time of the change from conventional film to hard-copy computerized radiography and of the subsequent move to soft-copy images on picture archiving and communication system (PACS) workstations.MATERIALS AND METHODS. A controlled before and after research design was undertaken. Data were collected on four occasions: two relating to conventional film, one relating to hard-copy computerized radiography, and one relating to soft-copy PACS images, Data collection was by direct observation of radiology reporting sessions by independent health service researchers. Data were collected on report times, details of images viewed, characteristics of the radiologist, and details of interruptions. To control for potential biases in the before and after comparisons, ordinary least squares multiple regression analysis was used. The principal comparison was between reports with PACS and reports with computerized radiography hard-copy because no change was noted in the organization of the reporting process between these two data collection rounds other than the introduction of the PACS.RESULTS. Data were collected on a total of 5568 report observations. Report time in the PACS data collection period was not significantly different (p = .32) than that in the computerized radiography hard-copy period. Reporting with the PACS was associated with significantly more (p < .01) historical images (i.e., images of the same patient obtained in previous examinations) being viewed.CONCLUSION. Report time was not lengthened by the introduction of the PACS. The finding that more historical images were viewed when the PACS was in use indicates that the PACS brought about a positive change in reporting practice.
