The goal was to develop and evaluate a modular system for measurement of the work times required by the various professional groups involved in radiation oncology before, during, and after serial radiation treatment (long-term irradiation with 25-28 fractions of 1.8 Gy) based on the example of rectal cancer treatment.
A panel of experts divided the work associated with providing radiation oncology treatment into modules (from the preparation of radiotherapy, RT planning and administration to the final examination and follow-up). The time required for completion of each module was measured by independent observers at four centers (Rostock, Bamberg, Düsseldorf, and Offenbach, Germany).
A total of 1,769 data sets were collected from 63 patients with 10-489 data sets per module. Some modules (informed consent procedure, routine treatments, CT planning) exhibited little deviation between centers, whereas others (especially medical and physical irradiation planning) exhibited a wide range of variation (e.g., 1 h 49 min to 6 h 56 min for physical irradiation planning). The mean work time per patient was 12 h 11 min for technicians, 2 h 59 min for physicists, and 7 h 6 min for physicians.
The modular system of time measurement proved to be reliable and produced comparable data at the different centers. Therefore, the German Society of Radiation Oncology (DEGRO) decided that it can be extended to other types of cancer (head and neck, prostate, and breast cancer) with appropriate modifications.
本研究旨在开发和评估一个模块化系统，用于测量放射肿瘤学相关专业人员在直肠癌治疗中（基于 25-28 次 1.8 Gy 分割放疗的长期照射）治疗前、治疗中和治疗后的各项工作时间，以此为例。
一组专家将与放射肿瘤学治疗相关的工作分为模块（从放射治疗准备、RT 计划和管理到最终检查和随访）。四个中心（德国罗斯托克、班贝格、杜塞尔多夫和奥芬巴赫）的独立观察者测量了每个模块完成所需的时间。
从 63 名患者中收集了 1769 组数据，每个模块的患者数量为 10-489 组。一些模块（知情同意程序、常规治疗、CT 计划）在各中心之间的差异较小，而其他模块（特别是医疗和物理照射计划）差异较大（例如，物理照射计划的时间范围为 1 小时 49 分钟至 6 小时 56 分钟）。技术员的平均每位患者工作时间为 12 小时 11 分钟，物理学家为 2 小时 59 分钟，医生为 7 小时 6 分钟。
时间测量的模块化系统被证明是可靠的，并在不同中心产生了可比的数据。因此，德国放射肿瘤学会（DEGRO）决定可以对其他类型的癌症（头颈部、前列腺和乳腺癌）进行适当修改后进行扩展。
