Mathematical model optimized for prediction and health care planning for COVID-19.

Abstract

The COVID-19 pandemic has threatened to collapse hospital and ICU services, and it has affected the care programs for non-COVID patients. The objective was to develop a mathematical model designed to optimize predictions related to the need for hospitalization and ICU admission by COVID-19 patients. Prospective study. Province of Granada (Spain). COVID-19 patients hospitalized, admitted to ICU, recovered and died from March 15 to September 22, 2020. The number of patients infected with SARS-CoV-2 and hospitalized or admitted to ICU for COVID-19. The data reported by hospitals was used to develop a mathematical model that reflects the flow of the population among the different interest groups in relation to COVID-19. This tool allows to analyse different scenarios based on socio-health restriction measures, and to forecast the number of people infected, hospitalized and admitted to the ICU. The mathematical model is capable of providing predictions on the evolution of the COVID-19 sufficiently in advance as to anticipate the peaks of prevalence and hospital and ICU care demands, and also the appearance of periods in which the care for non-COVID patients could be intensified.
