Background: The knowledge about the epidemiological profile of patients admitted to the hospital for severe COVID infection, allows an adequate health care planning and resource allocation.
Aim: To describe the epidemiology of patients with COVID-19 admitted to a public hospital between March 2020 and July 2021.
Material and methods: Demographic variables, comorbidities, ventilatory support requirements, and hospital resources were recorded from clinical records and hospital databases of diagnosis related groups. The primary outcomes were overall mortality and need of ventilatory support.
Results: In the study period, 4,474 patients (56% males) were hospitalized with a diagnosis of COVID-19. Overall mortality was 25.8% and in-hospital mortality was 18%. Invasive and non-invasive ventilatory support was required in 1349 (30.2%) and 2060 (46%) patients, respectively. The most common comorbidities in admitted patients were diabetes mellitus (29.2%), chronic kidney disease (11.1%), and chronic liver disease (10.4%). The readmission rate was 3.2%.
Conclusions: Mortality associated with COVID-19 in this hospital was similar to the rates reported abroad. Local risk predictors for this infection should be identified.
