Hypofractionation, delivering higher radiation doses in fewer sessions, is a promising solution. This study assesses its cost-effectiveness and impact on treatment slots within the isoresources model. Image from reference number 1:

Material/Methods: We compared patient data from April to October 2023 and 2024, focusing on hypofractionation introduced in March 2023. We analyzed the number of patients treated, adherence to regional priority codes, and average waiting time from consultation to radiotherapy initiation, involving 1399 patients. Results: Hypofractionation allowed 147 additional patients to be treated within the study period without exceeding regional priority codes. In 2023, 626 patients were treated, while 773 received treatment in 2024. The average waiting time increased by only 2 days, enhancing patient throughput while maintaining compliance (see attached table).
