[Predictive scale of acute kidney failure in sepsis (ARMO)]

To define the predictive utility of the adapted scale of Acute Renal Injury (ARMO) in septic patients in the Intensive Care Units of two hospitals in Quito during the period 2020 to 2021.

Observational, descriptive, ambispective, multicenter study of septic patients in two Intensive Care Units in the city of Quito, Ecuador, with a sample of 197 patients, with data within the first 72 hours of admission, analysis of demographic and clinical variables, therapeutic and intervention measures, values of prognostic scales and multivariate analysis with logistic regression.

200 patients were analyzed, with a median age of 57 years, 41 % (82) presented kidney failure, and 40.96 % corresponded to KDIGO stage 3. 11.5 % of patients with kidney injury required renal replacement therapy. After multivariate analysis, it was determined that: GFR ≤84 ml/min/1.73m2, serum lactate ≥2.5 mmol/l, SOFA ≥10 points and urinary output ≤0.6 ml/Kg/h are predictors of renal failure. Based on this, a new predictive scale for acute renal failure, ARMO score, with a ROC curve of 0.836 (95 % CI, 0.781-0.890) with a cut-off point of 8 points, is proposed.

The adapted scale of Acute Renal Injury (ARMO) shows a high discriminative capacity.
