Adapting for Adaptive Radiotherapy (ART): The need to evolve our roles as Therapeutic Radiographers. (October 2021) - Tsang, Y.M.
Abstract: Objectives: 4D Adaptive Radiotherapy (4D-ART) has been stated as the future baseline standard-of-care for technical radiotherapy. Its goal is to optimise radiation dose received by 'adapting' to changes 'seen' in each individual patient, for each treatment delivery (fraction), throughout each treatment delivery. The drive for technological developments to achieve this is ongoing. To enhance the potential benefits, we should consider other aspects of the processes needed: How do changes in clinical practices and processes affect the role of the Therapeutic Radiographer? The aim is to raise the need to explore questions of Therapeutic Radiographers roles and responsibilities within 4D-ART. Key findings: Moving from using current predictive strategies (such as plan-of-the-day) to being able to dynamically adapt (real-time/4D-ART) for patient changes requires rapid clinical judgements to be made. The question becomes 'who makes these decisions'? Currently Therapeutic Radiographers maybe ideally placed for this. Dynamically adaptive radiotherapy requires Radiographers to have clinical decisions-making skills and authorities within the multi-professional team (MPT). It is not sufficient to train radiographers in the 'how' to use 4D-ART techniques and technologies; the ability to make good clinical judgments comes from understanding the principles supporting this concept by understanding the 'why'. Conclusion: To support future service needs and ongoing developments within ART, Radiographer's roles need to adapt and evolve, as well as the way their role is perceived within the MPT. We need to provide Radiographers with the education required, abilities and authorities to act. Implications for practice: Role revision is required to include greater responsibility for clinical decision making for implementing 4D-ART practices.
