The purpose of this study was to determine the impact of filmless imaging on the frequency with which physicians access radiology images and to assess clinician perception of image accessibility using a hospital-wide Picture Archival and Communication System (PACS). Quantitative data were collected at the Baltimore VA Medical Center (BVAMC), prior to and after conversion to filmless imaging, to determine the frequency with which clinicians access radiology images. Survey data were also collected to assess physician preferences of image accessibility, time management, and overall patient care when comparing filmless and film-based modes of operation. In general, there was a significant increase in the average number of radiology images reviewed by clinicians throughout the hospital. However, the one are in the hospital where this trend was not observed was in the intensive care unit (ICU), where the frequency of image assess was similar between film and filmless operations. Ninety-eight percent of clinicians surveyed reported improved accessibility of images in a filmless environment resulting in improved time management. The mean clinician estimate of time saved due to the use of PACS was 44 minutes. The study documented a combination of clinician perception of improved accessibility and substantial time savings with the use of a hospital-wide PACS, which was supported by objective measurements. The increased frequency of image review by clinicians and rapid image access should provide a further impetus to radiologists to decrease report turnaround time to provided "added value" for patient care.
本研究的目的是确定无胶片成像对医生获取放射影像频率的影响，并使用全院范围的图像存档与通信系统（PACS）评估临床医生对图像可及性的认知。在巴尔的摩退伍军人医疗中心（BVAMC）向无胶片成像转换之前和之后收集定量数据，以确定临床医生获取放射影像的频率。还收集了调查数据，以比较无胶片和基于胶片的操作模式时医生对图像可及性、时间管理和整体患者护理的偏好。总体而言，全院临床医生查看的放射影像平均数量显著增加。然而，医院中未观察到这种趋势的一个区域是重症监护病房（ICU），在该病房，胶片和无胶片操作的图像评估频率相似。98%接受调查的临床医生报告称，在无胶片环境下图像可及性得到改善，从而使时间管理得到改善。临床医生因使用PACS而节省时间的平均估计为44分钟。该研究记录了临床医生对可及性改善的认知与使用全院范围PACS带来的大量时间节省的结合，这得到了客观测量的支持。临床医生查看图像频率的增加和图像的快速获取应进一步促使放射科医生缩短报告周转时间，为患者护理提供“附加值”。
