Introduction: Since the emergence of the first cases in China, the treatment of patients with COVID-19 has proved to be a challenge for health systems around the world, initiating a global effort to investigate the clinical, epidemiological aspects and factors disease prognosis (Galvão et al. 2020). Objective/s: Determine the factors that influence mortality in patients hospitalized with Sars-Cov-2. Methods: Descriptive, retrospective and correlational study, in a cross-sectional cohort, in a non-probabilistic convenience sample of 1687 patients with Sars-Cov-2 admitted to the CHTV, from 03/17/2020 to 08/31/2021. Results: The overall mortality rate was 26%, being higher in older patients. On admission, the presence of oxygen and arterial blood gas values ​​had a statistically significant relationship with mortality. There was a 42% increase in mortality in people admitted to the ICU (Intensive Care Unit) and the presence of at least one bacterial infection increased the risk of death by 50%. The need for NIV (Non-Invasive Ventilation) doubled the likelihood of dying. The mortality rate increased proportionally with the number of comorbidities, with the presence of at least one increasing the risk of dying by 55%. Conclusion: Understanding the factors that influence mortality in patients with Sars-Cov-2 is, even today, a challenge. The results of this study reinforce the existing evidence on the risk factors that influence mortality in victims with Sars-Cov-2 and alert health professionals to the need to implement, at an early stage, an action aimed at the uniqueness of the clinical state of each person.
