BARBOSA, Stephany et al. Change of in-hospital mortality during the first SARS-COV-2 surge in Bogotá, Colombia. Infect. [online]. 2022, vol.26, n.2, pp.156-160.  Epub Dec 12, 2021. ISSN 0123-9392.


Mortality secondary to SARS-COV 2 has decreases around the world, however this has not been evaluated in Colombia neither has the correlation between patient characteristics or treatments.


To compare the mortality due to SARS-COV-2, in two periods of time, controlling risk factors associated with mortality.


Observational retrospective cohort study of patients with SARS- COV-2 treated at the San Ignacio University Hospital in Bogotá (Colombia), from March 19 to November 12, 2020. The in-hospital mortality rate of patients discharged before and after August 21, 2020 (surge mortality in Colombia) was com pared. The impact of the moment of attention was analyzed controlled by comorbidities, severity at admission and treatment received using a bivariate and multivariate logistic regression model.


1399 patients (944 before and 455 after August 21) were analyzed. The overall in-hospital mortality rate was similar at both times (17.6%vs16.3percentage, p=0.539). In the multivariate analysis, it was found that the moment of attention was associated with lower mortality (OR 0.66 95% CI0.47;0.93,p=0.018), in contrast to its increase associated with age (OR 1.06 95% CI 1.05;1.07,p=<0.001), male sex (OR 1.84 95%CI 1.33;2.54,p=<0.001), cirrhosis (OR1.89 95%CI 1.24;2.88, p=0.003), kidney disease (OR 1.36 95% CI1.00;1.83,p=0.043) and the use of dexamethasone (OR1.53 95%CI 1.03;2.28,p=0.031).


The in-hospital mortality rate fell after August 21 during the first wave of the pandemic in Bogotá-Colombia, possibly associated with an improvement in response capacity, or a lower viral inoculum of infected patients. These findings may change with the saturation of the health system
