Hospitalized patients with COVID-19: One-year pandemic report

Background: There is limited information about the variations of the clinical characteristics and outcomes in hospitalized patients with COVID-19 during the pandemic. No study has evaluated these changes in our region. Objective: To assess the clinical characteristics and outcomes of adult hospitalized patients with COVID-19 during the first year of the pandemic. Methods: This is a retrospective, observational study. Medical charts of hospitalized patients with COVID-19 at the Hospital Centro Medico de Caracas were reviewed to obtain information about their clinical characteristics. Results: A total of 454 patients were included, 278 men (61 %) and 176 women (39 %), with an average age of 61.97±15.95 years, previous duration of symptoms 7.38 ± 4.01 days, chest CT score 11.49±5.80, and hospital stay 8.30±5.11 days. 59.8 % of the patients had severe-critical disease, 40.2 % mild-moderate, 15.86 % were admitted to the ICU, 81.2 % were discharged and 9.5 % had died. The curve of hospitalized cases was bimodal, identifying two waves: The first between July-September 2020 (peak in August with 59 cases), the second larger and longer between December 2020 and April 2021 (peak in March 2021 with 140 cases). The length of hospital stay remained stable over one year, while mortality decreased progressively (highest value in August 2020, 26.4 % and the lowest in March 2021, 5.4 %). Conclusion: The results show the behavior of hospitalized patients with COVID-19 during a year of the pandemic in our population. It is reasonable that the decline in mortality rate is the result of changes in the age of patients, the disease severity, and provision of care during the pandemic. © 2021 Academia Nacional de Medicina.
