Abstract

COVID-19 challenged our health system, within the broad clinical spectrum acute kidney injury was presented as a catastrophic event, acute kidney injury and the risk of dependency after dialysis constitute a clinical problem with high repercussions in the funcionality. To identify risk factors for dialysis dependence after acute kidney injury from COVID-19. A retrospective observational cohort study was carried out at the Hospital de Especialidades del Centro Médico Nacional Siglo XXI, of the Mexican Institute of Social Security, from March 2020 to March 2021. 317 patients were included, we performed descriptive statistics, we compared differences between the stages of acute kidney injury, finding a difference in obesity with a frequency of 2.2% in stage 1, 20.82% stage 2 and 14.51% stage 3, with p value = 0.018. We found dialysis dependence one year after hospital-acquired acute kidney injury induced by COVID-19 in 58 patients (18.9%), we analyzed by KDIGO stage, in those patients who had AKI KDIGO 1 (2.83%) it depended on dialysis at one year, in the KDIGO stage 2 (3.78%), in the KDIGO stage 3 (11.67%). Our study allowed us to identify that the risk factors associated with dialysis dependence are: male gender, type 2 diabetes mellitus, obesity, cardiovascular disease.
