Risk factors for Mortality in Patients with COVID-19 in Cuernavaca- Morelos

Background: The world changed in December 2019 due to respiratory tract infection cases, initially of unknown etiology, later known as COVID-19. Objective: This study aimed to determine the factors and comorbidities associated with mortality from COVID-19 in Mexico. Methods: It was a cross-sectional and observational prospective study of patients treated at an IMSS (Mexican Institute of Social Security) Hospital in Morelos with a confirmed diagnosis of COVID-19. Logistic regression models and survival analyses were developed to identify factors associated with mortality risk. Results: 3,965 patients were analyzed, with most deaths occurring in men. The mortality risks were higher in men who were older than 50 years. The most significant associations were: age older than 80 years (HR:3.17), endotracheal intubation (HR:1.54), dyspnea (HR: 13.55), and polypnea (HR:1.54). Conclusion: The risk of death in this population was high, considering the absence of primary protective measures at the beginning of the pandemic and the lack of consistency in using personal protection elements.
