Acute renal failure (ARF) is one of the most frequent complications in hospitalized patients and is a risk factor for mortality. It is extremely important to identify the association of clinical factors that worsen mortality in patients with ARF admitted to an intensive care unit (ICU). A total of 218 patients were included, of which 63.7% (n=139) were men with a mean age of 43±19 years. The correlation analysis of control, dependent, and independent variables was done through Spearman's coefficient and the OR was analyzed through logistic regression. Of the 218 patients, 33% (n=72) died in the ICU. ARF occurred in 28.4% (n=62) of all patients and of these, 61.3% (n=38) died, with an OR of 4.94 (p 0.0001). The highest proportion of deceased patients were in the AKIN 3 category. The clinical variables of mechanical ventilation (PR 3.57, 95% CI, 0.34-37.93), use of vasoactive drugs (PR 8.32, 95% CI, 3.20-21.64), APACHE III score (PR 1.12, 95% CI, 1.03-1.23), age (PR 1.01, 95% CI, 0.99-1.04) and those who underwent surgery (PR 0.28, 95% CI, 0.10-0.80) had a positive association and increased mortality.

The presence of clinical variables of mechanical ventilation, the use of vasoactive drugs, sepsis, APACHE III stage, age, AKIN 3 category, and a history of surgery before admission to the ICU significantly increase mortality in patients with ARF in ICU.
