Modelagem e otimização aplicadas no agendamento de cirurgias ortopédicas

Abstract

The work addressed to the planning of orthopedic surgeries using mathematical programming. It aims to portray the importance of the different sectors involved in surgical management in a weekly surgery allocation plan, calculating the weekly times used to perform surgeries and the number of procedures performed throughout the week and balancing the vacancies in beds for recovery of patients in the postoperative period. Firstly, the mathematical modeling was presented to solvethe problem, followed by the computational experiments containing all the scenarios used by programming. The total amount of time of use of the operating room for surgeries throughout the week, the total number of surgeries performed in the period, and the division of beds allocated by the model implemented for each orthopedic subspecialty under study were presented. Based on works in the literature that corroborate the planning proposed in this study, the importance of employing mathematical programming in research that addresses the use of the operating room was reinforced based on modeling that aims to maximize the time of operating rooms to perform surgeries, and that contemplates the balance in the use of this space. It is concluded that in order to reduce the waiting time in queues, the structuring of the planning elaborated by the mathematical modeling must contemplate the flow of patients in and out of the operating rooms, keeping balance at all stages of the process, and aiming to overcome the number minimum of surgical procedures to meet the stipulated demand.
