Clinical outcomes in patients who need acute renal replacement therapy in the intensive care unit

Abstract Objective: to establish the renal outcomes of patients needing dialysis due to acute kidney injury who were admitted to the intensive care unit at Hospital Departamental Universitario Santa Sofía de Caldas from 2006 to 2018, and determine the factors associated with these outcomes. Methods: a retrospective cohort study carried out at Hospital Departamental Universitario Santa Sofía de Caldas on 122 patients over the age of 18 who required dialysis in the intensive care unit due to acute kidney injury, from 2006 to 2018. The major adverse kidney events (MAKE) composite outcome was evaluated, composed of partial recovery of kidney function, dialysis dependence and death, with 90-day and one-year follow up. Results: there is a relationship between diabetes, the APACHE II score, metabolic acidosis, anuria and the dialysis start time and MAKE at 90 days and one year. In the logistic regression, patients who developed MAKE at 90 days had a greater probability of having had anuria (OR=6.71; 95%CI: 1,497-30,076), acidosis (OR=4,349; 95%CI: 1,616-11.7) and a late treatment start (OR=3,013; 95%CI: 1,241-7,316). The one-year MAKE showed similar results, with the addition of the continu ous therapy modality (OR=2,841; 95%CI: 1,193-6,763). Conclusions: diabetes, a high APACHE II, anuria, metabolic acidosis and late dialysis treat ment are more frequent in patients who develop MAKE. (Acta Med Colomb 2022; 47.
