PurposeRadiotherapy (RT) treatment and treatment planning is a complex process prepared and delivered by a multidisciplinary team of specialists. Efficient communication and notification systems among different team members are therefore essential to ensure the safe, timely delivery of treatments to patients.MethodTo address this issue, we developed and implemented automated notification systems and an electronic whiteboard to track every CT simulation, contouring task, the new‐start schedule, and physician's appointments and tasks, and notify team members of overdue and missing tasks and appointments. The electronic whiteboard was developed to have a straightforward view of current patients’ planning workflow and to help different team members coordinate with each other. The systems were implemented and have been used at our center to monitor the progress of treatment‐planning tasks for over 2 years.ResultsThe last‐minute plans were relatively reduced by about 40% in 2023 compared to 2021 and 2022 with a p‐value < 0.05. The overdue contouring tasks of more than 1 day decreased from 46.8% in 2019 and 33.6% in 2020 to 20%–26.4% in 2021–2023 with a p‐value < 0.05 after the implementation of the notification system. The rate of plans with 1–3 day planning time decreased by 20.31%, 39.32%, and 24.08% with a p‐value < 0.05 and the rate of plans with 1–3 day planning time due to the contouring task overdue more than 1 day decreased by 49.49%, 56.89%, and 46.52% with a p‐value < 0.05 after the implementation. The rate of outstanding appointments that are overdue by more than 7 days decreased by more than 5% with a p‐value < 0.05 following the implementation of the system.ConclusionsOur experience shows that this system requires minimal human intervention, improves the treatment planning workflow and process by reducing errors and delays in the treatment planning process, positively impacts on‐time treatment plan completion, and reduces the need for compressed or rushed treatment planning timelines.
