To assess whether alterations in the type of duty assignment system can affect the reading efficiency and stress level of diagnostic radiologists.
Fourteen board-certified diagnostic radiologists were enrolled. We investigated three different reading systems for 1 week each. System 1 is our default, in which there are no assigned duties and everyone finishes when all cases are done. In system 2, two late shift readers are assigned every day, and, after everyone else leaves at a fixed time (5:30 p.m.), they take all remaining cases until they are finished. In system 3, a dedicated single reader is assigned to finish 30 cases, and everyone else will read all remaining cases. The total time required for reading and the number of cases read were recorded. In addition, participants completed two questionnaires regarding work-related stress.
There was a trend toward shorter finishing time in system 2 and 3 compared to system 1 (P = 0.072 and 0.012). In terms of working stress, the subjective burden was lighter when systems 2 or 3 were employed.
Minor modification of the duty assignment system has the potential to improve working efficiency and may reduce the work-related stress of diagnostic radiologists.
评估职责分配系统类型的改变是否会影响诊断放射科医生的阅读效率和压力水平。
招募了14名获得委员会认证的诊断放射科医生。我们对三种不同的阅读系统分别进行了为期1周的调查。系统1是我们的默认系统，即没有指定职责，所有人在所有病例读完后下班。在系统2中，每天安排两名晚班阅片医生，在其他人固定时间（下午5:30）下班后，他们处理所有剩余病例，直到完成。在系统3中，指定一名专门的阅片医生完成30个病例，其他所有人阅读所有剩余病例。记录阅读所需的总时间和阅片病例数。此外，参与者完成了两份关于工作相关压力的问卷。
与系统1相比，系统2和系统3的完成时间有缩短的趋势（P = 0.072和0.012）。在工作压力方面，采用系统2或系统3时主观负担较轻。
职责分配系统的微小改变有可能提高工作效率，并可能减轻诊断放射科医生的工作相关压力。
