Resumo
As distâncias aos equipamentos de diagnóstico PET-CT precisam ser
reduzidas para que pacientes tenham um rápido diagnóstico de doenças, e como
consequência, maior chance de sobrevivência através da detecção e início de
tratamento forma precoce. Logo, este estudo vai abordar a análise de como estão
distribuídos os equipamentos PET-CT no território brasileiro, e o que deve ser feito
para melhorar o acesso da população a este. A plotagem de dados em mapas para
visualização e análise de resultados demonstraram que Brasil possui uma quantidade
insuficiente de PET-CTs para atender de forma adequada às demandas da população
em relação aos exames específicos de diagnostico, proporcionados somente por este
equipamento. Então, uma proposta de localização de novos equipamentos foi realizada
através do solver Location-allocation Problem com a utilização dos métodos Minimize
Weighted Impedance (P-Median), Maximize Coverage e Maximize Attendance. O
algoritmo em linguagem Python foi executado dentro de um notebook no ambiente do
software ArcGIS Pro Desktop, e como resultado, dentro dos parâmetros introduzidos,
indicou a necessidade de 512 equipamentos adicionais aos 119 já existentes no pais. E,
ainda assim, devido a heterogeneidade do território brasileiro, 15.403.911 habitantes
ficaram sem acesso a um PET-CT dentro das restrições determinadas no algoritmo
Distances to PET-CT diagnostic equipment need to be reduced so that patients can have a rapid diagnosis of diseases, and as a consequence, have a greater chance of survival through early detection and initiation of treatment. Therefore, this study will address the analysis of how PET-CT equipment is distributed in the Brazilian territory and what should be done to improve the population's access to it. Plotting data on maps for visualization and analysis of results showed that Brazil has an insufficient amount of PET-CTs to adequately meet the demands of the population in relation to specific diagnostic tests, provided only by this equipment. So, a proposal for locating new equipment was made using the Location-allocation Problem solver through the methods Minimize Weighted Impedance (P-Median), Maximize Coverage, Maximize Attendance. The algorithm in Python language was executed inside a notebook in the ArcGIS Pro Desktop software environment, and as a result, within the parameters introduced, it indicated a necessity of 512 additional equipments to the 119 already existing in the country. Besides that, due to the heterogeneity of the Brazilian territory, 15.403.911 inhabitants were without access to a PET-CT within the restrictions determined in the algorithm.
