“…Workflow issues associated with bariatric patients are discussed in the literature, establishing that this demographic takes longer to set up due to the mobility of skin tattoos relative to bony structures. 13,17 Additionally, they are more prone to set up errors and require daily imaging to ensure target accuracy. 8,13,17 Winters and Poole 13 observed in their focus group interviews of radiation therapists that obese patients took longer to mount and dismount the bed, which, in addition to longer set up time and increased imaging requirements, further increased time delays on the treatment unit.…”

“…9,10 Physical constraints such as the diameter of computed tomography (CT) scanners and the weight tolerances of machine tables have been explored. [11][12][13] Furthermore, immobilisation equipment comfort, accuracy and reproducibility have been investigated across a variety of body habitus. [14][15][16] The author's research demonstrated that consideration of patient BMI is important when selecting the most effective immobilisation equipment.…”

“…[14][15][16] The author's research demonstrated that consideration of patient BMI is important when selecting the most effective immobilisation equipment. In addition to this, studies have shown the obese population frequently required daily imaging with correctional shifts, 8,13,17 concluding that obese patients were at a greater risk of geographical miss compared to non-obese patients.…”

Introduction: Radiation therapy (RT) offers a less invasive management option for bariatric cancer patients. As the proportion of Australians categorised overweight or obese approaches 70%, it is not well understood how this growth will impact RT departments. The aim of this study was to evaluate the current and potential future body mass index (BMI) of RT patients at one centre, with the purpose of identifying variables that may impact resource planning decisions. Methods: De-identified demographic data including gender, age, diagnosis code, activity code and BMI were obtained from MOSAIQâ oncology information system for 5548 courses of RT commenced between 2017 and 2020, and retrospectively analysed. Descriptive statistics were used to summarise the data. Simple and multiple linear regression was used to analyse for statistically significant relationships between variables. Results: Of all patient courses, 64% were overweight or obese. Average BMI increased over time by 0.3 kg/m 2 per year. Courses related to the young and elderly had a lower average BMI. Breast, brain/skull, and pelvis/prostate treatment sites had a significant association with a higher average BMI. Thorax treatment sites had a lower average BMI, but this average is increasing at the fastest rate of all treatment sites. Prone breast courses had an average BMI 5.58 kg/m 2 higher than IMRT/VMAT courses. Conclusion: Results demonstrate that patient BMI is increasing. Resources related to breast courses (breast board, prone board) and thorax courses (lung board) may experience increased strain in the future. Modifications to department workflow and scheduling are likely required. Further research into staffing implications is recommended.

“…Substantial evidence has shown that obesity represents a challenge in the RT of gynecologic cancers. 8 Obese patients and patients with a large hip circumference (HC) and umbilical anterior–posterior diameter had greater setup displacements, 9 , 10 , 11 , 12 , 13 because treatment requires daily imaging to ensure reproducibility of setup. Otherwise, expanding the target volumes may be necessary, especially where daily imaging is not practicable, which is the case in settings with reduced resources or high patient flow or particular circumstances, such as the coronavirus disease 2019 pandemic.…”

“An evaluation of radiation therapy patient body mass index trends and potential impact on departmental resource planning” by Laing et al. The authors’ comment that research into the experiences of larger bodied patients should focus on compassionately improving care for this patient population rather than framing large‐bodied patients as a burden or problem, and should include commentary on the effects of weight‐bias in the healthcare system.
