We aimed to determine the effect of PACS implementation on the radiologist reporting time and utilization of radiology services in a hospital in Iran. This study was conducted in three 6-month periods (before PACS implementation, immediately after the implementation, and 1 year after implementation). Data related to reporting time of CT examinations were collected from 5074 patients with 6613 examinations and compared using the Friedman test. The utilization rate of radiology services was conducted about CT scans and radiographies. Therefore, 17,862 patients with 36,321 radiographies and 7155 patients with 10,571 CT scans were evaluated, and the ratio of the number of examinations to the number of patients and patient days was compared in three periods. The mean of reporting time on CT scan examinations in the period of immediately after PACS was changed compared to the period of before PACS from 13.05 to 24.18 days and compared to 1 year after PACS implementation, to 4.14 days (P value < 0.05). The utilization rate in CT scans, 1 year after PACS increased at least 10% to 25% compared to the immediately after PACS and before implementing PACS. The utilization rate in radiographies, 1 year after PACS, increased at least 16% to 78% compared to the immediately after PACS and before PACS implementation. In conclusion, the mean of the radiologist reporting time for CT scans is significantly decreased by PACS in the long-term. Additionally, the utilization rate of radiology services is increased in the short- and long-term after PACS implementation in most examinations of CT scan and radiography examinations.
我们旨在确定在伊朗一家医院实施 PACS 对放射科医生报告时间和放射科服务利用的影响。这项研究分为三个 6 个月的阶段（在 PACS 实施之前、实施之后立即以及实施之后 1 年）进行。从 6613 次 CT 检查的 5074 名患者中收集有关报告时间的数据，并使用 Friedman 检验进行比较。放射科服务的利用率是关于 CT 扫描和射线照相术的。因此，评估了 17862 名患者的 36321 次射线照相术和 7155 名患者的 10571 次 CT 扫描，比较了三个时期内检查次数与患者数和患者天数的比例。与 PACS 实施前相比，PACS 实施后立即进行 CT 扫描检查的报告时间平均值从 13.05 天变为 24.18 天，与 PACS 实施 1 年后相比，报告时间平均值变为 4.14 天（P 值<0.05）。与 PACS 实施后立即相比，PACS 实施 1 年后 CT 扫描的利用率至少增加了 10%至 25%。与 PACS 实施后立即和 PACS 实施前相比，PACS 实施 1 年后射线照相术的利用率至少增加了 16%至 78%。总之，长期以来，PACS 显著降低了 CT 扫描的放射科医生报告时间平均值。此外，在 PACS 实施后的短期和长期内，大多数 CT 扫描和射线照相术检查的放射科服务利用率均增加。
