OBJECTIVE:To improve safety and efficiency of radiotherapy process by customizing a Varian ARIA oncology information system following the guidelines provided in AAPM TG-100 report. METHODS:First, failure mode and effects analysis (FMEA) and quality management program were implemented for radiotherapy process. We have customized the visual care path in the ARIA system and set up a series of templates for simulation, prescription, contouring, treatment planning, and multiple checklists. Average time of activities’ completion and amount of planning errors were compared before and after the use of the customized ARIA to evaluate its impact on the efficiency and safety of radiotherapy. RESULTS:Completion time and on-time completion rate of the key activities in the care path are improved. The time of OAR/targets contouring decreases from (1.94±1.51) days to (1.64±1.07) days (p = 0.003), with the on-time completion rate increases from 77.4%to 83.3%(p = 0.048). Treatment planning time decreases from (0.81±0.65) days to (0.55±0.51) days (p < 0.001), with the on-time completion rate increases from 96.6%to 98.3%(p = 0.163). Waiting time of patients decreases from (4.50±1.83) days to (4.04±1.34) days (p < 0.001), with the on-time completion rate increases from 81.9%to 89.7%(p = 0.003). In addition, the average plan error rate decreases from 5.5%(2.9%for safety errors and 2.6%for non-normative errors) to 2.4%(1.6%for safety errors and 0.8%for non-normative errors) (p = 0.029). CONCLUSION:Our study demonstrates that the customized ARIA system has the potential to promote efficiency and safety in radiotherapy process management. It is beneficial to organize and accelerate the treatment process with more effective communications and fewer errors.

使用定制的 ARIA 肿瘤学信息系统提高放射治疗的安全性和效率

目的：按照 AAPM TG-100 报告中提供的指南，通过定制 Varian ARIA 肿瘤学信息系统来提高放射治疗过程的安全性和效率。方法：首先，对放疗过程实施失效模式和影响分析（FMEA）和质量管理程序。我们在 ARIA 系统中定制了视觉护理路径，并设置了一系列用于模拟、处方、轮廓、治疗计划和多个检查表的模板。比较了使用定制 ARIA 前后活动完成的平均时间和计划错误的数量，以评估其对放射治疗效率和安全性的影响。结果：护理路径中关键活动的完成时间和按时完成率都有所提高。OAR/目标轮廓的时间从（1.94±1. 51）天到（1.64±1.07）天（p = 0.003），准时完成率从77.4％增加到83.3％（p = 0.048）。治疗计划时间从（0.81±0.65）天减少到（0.55±0.51）天（p < 0.001），按时完成率从96.6%提高到98.3%（p = 0.163）。患者候诊时间从（4.50±1.83）天减少到（4.04±1.34）天（p < 0.001），按时完成率从81.9%提高到89.7%（p = 0.003）。此外，平均计划错误率从 5.5%（安全错误为 2.9%，非规范错误为 2.6%）降至 2.4%（安全错误为 1.6%，非规范错误为 0.8%）（p = 0.029） . 结论：我们的研究表明，定制的 ARIA 系统具有提高放射治疗过程管理效率和安全性的潜力。
