Clinical characteristics of critically ill patients with COVID-19.

Coronavirus disease 2019 (COVID-19) pandemic poses a major challenge for healthcare systems. In South America, local information about the incidence and clinical characteristics of critically ill patients diagnosed with COVID-19 is still limited. In this observational and retrospective study, we aimed to describe critically ill patients' clinical and respiratory characteristics with COVID-19.

Changes in the management and clinical outcomes of critically ill patients without COVID-19 during the pandemic.

Objective: To analyze whether changes in medical care due to the application of COVID-19 protocols affected clinical outcomes in patients without COVID-19 during the pandemic.

Methods: This was a retrospective, observational cohort study carried out in a thirty-eight-bed surgical and medical intensive care unit of a high complexity private hospital. Patients with respiratory failure admitted to the intensive care unit during March and April 2020 and the same months in 2019 were selected.
