The objective of this study is to investigate the workload for radiologists during on-call hours and to quantify the 15-year trend in a large general hospital in Western Europe.
Data regarding the number of X-ray, ultrasound and computed tomography (CT) studies during on-call hours (weekdays between 6.00 p.m. and 7.00 a.m., weekends, and national holidays) between 2006 and 2020 were extracted from the picture archiving and communication system. All studies were converted into relative value units (RVUs) to estimate the on-call workload. The Mann-Kendall test was performed to assess the temporal trend.
The total RVUs during on-call hours showed a significant increase between 2006 and 2020 (Kendall's tau-b = 0.657, p = 0.001). The overall workload in terms of RVUs during on-call hours has quadrupled. The number of X-ray studies significantly decreased (Kendall's tau-b = - 0.433, p = 0.026), whereas the number of CT studies significantly increased (Kendall's tau-b = 0.875, p < 0.001) between 2006 and 2020. CT studies which increased by more than 500% between 2006 and 2020 are CT for head trauma, brain CTA, brain CTV, chest CT (for suspected pulmonary embolism), spinal CT, neck CT, pelvic CT, and CT for suspected aortic dissection. The number of ultrasound studies did not change significantly (Kendall's tau-b = 0.202, p = 0.298).
The workload for radiologists during on-call hours increased dramatically in the past 15 years. The growing amount of CT studies is responsible for this increase. Radiologist and technician workforce should be matched to this ongoing increasing trend to avoid potential burn-out and to maintain quality and safety of radiological care.
本研究的目的是调查放射科医生在值班时间的工作量，并量化西欧一家大型综合医院15年的趋势。
从图像存档与通信系统中提取2006年至2020年期间值班时间（工作日下午6点至上午7点、周末和国家法定节假日）的X线、超声和计算机断层扫描（CT）检查数量的数据。所有检查都转换为相对价值单位（RVUs）以估计值班工作量。进行曼-肯德尔检验以评估时间趋势。
2006年至2020年期间，值班时间的总RVUs显著增加（肯德尔tau-b = 0.657，p = 0.001）。按RVUs计算，值班时间的总体工作量增加了两倍。2006年至2020年期间，X线检查数量显著减少（肯德尔tau-b = -0.433，p = 0.026），而CT检查数量显著增加（肯德尔tau-b = 0.875，p < 0.001）。2006年至2020年期间增加超过500%的CT检查是头部创伤CT、脑CT血管造影（CTA）、脑CT静脉造影（CTV）、胸部CT（用于疑似肺栓塞）、脊柱CT、颈部CT、盆腔CT以及疑似主动脉夹层的CT。超声检查数量没有显著变化（肯德尔tau-b = 0.202，p = 0.298）。
在过去15年中，放射科医生在值班时间的工作量急剧增加。CT检查数量的增加是导致这种增加的原因。放射科医生和技术人员的劳动力应与这种持续增长的趋势相匹配，以避免潜在的职业倦怠，并维持放射护理的质量和安全。
