The development and implementation of a radiation therapy bariatric protocol.

Abstract

The rate of obesity is increasing in the Australian population, and this also includes patients with cancer. The safety and dignity of this cohort of patients is paramount as well as the timely acquisition of equipment required to assist patients with obesity to complete a course of radiation therapy (RT). The design and manufacture of equipment used in most RT departments is not suitable for the weight or BMI of all patients presenting for treatment. RT also operates under a unique set of circumstances that differs from the routine hospital environment which prompted the design of an RT bariatric protocol for use in our department. The protocol is based on the mapping of a patient's pathway from simulation and treatment. Treatment technique and equipment limitations as well as information relating to a patient with high BMI are used as trigger points that direct a patient pathway. The bariatric protocol provides the RT team with decision-making support for appropriate resource utilisation ensuring safe and efficient treatment delivery for both the patient and staff. This paper will outline how the RT bariatric protocol was developed and implemented in our department, highlighting areas that required more attention due to the RT-specific environment.
