The High Specialty Regional Hospital of Ixtapaluca from Mexico is a tertiary care public institution with 348 hospital beds, 20 surgical specialties and 21 clinical specialties. The Hospital attends population from four states at the East of the Mexican Republic: Mexico, Hidalgo, Puebla, Tlaxcala, and the East of Mexico City. The Hospital has the Radiotherapy service with a linear accelerator (LINAC) that has been in operation since 2012. It has exceeded its useful life and, due to the increase in the incidence of oncological pathologies, the equipment is also overused. Additionally, there is a waiting list of 90 patients to begin treatment. That is why the Hospital is interested in purchasing a second LINAC. The objective of this work was to do a cost-to-benefit analysis for the acquisition of a new linear accelerator and the construction of the bunker. Clinical costs and benefits were estimated, which translated into potential monetary benefits to determine the feasibility of the project.
