MO417NEPHROLOGIST INTERVENTION TO AVOID KIDNEY REPLACEMENT THERAPY IN ACUTE KIDNEY INJURY

Abstract

Abstract Background and Aims Based on the pathophysiology of acute kidney injury (AKI) it is plausible that certain early interventions by the nephrologist could influence its trajectory. In this study, we investigated the impact of 5 early nephrology interventions on starting kidney replacement therapy (KRT), AKI progression and death. Method In a prospective cohort at Hospital Civil of Guadalajara, we followed-up for 10 days AKI patients in whom a nephrology consultation was requested. We analyzed 5 early interventions of the nephrology team (fluid adjustment, nephrotoxic withdrawal, antibiotic dose adjustment, nutritional adjustment and removal of hyperchloremic solutions) after propensity score and multivariate analysis for the risk of starting KRT (primary objective), AKI progression to stage 3 and death (secondary objectives). Results From 2017 to 2020 we analyzed 288 AKI patients. The mean age was 55.3 years, 60.7% were male, AKI KDIGO stage 3 was present in 50.5% of them, sepsis was the main etiology 50.3%, and 72 (25%) patients started KRT. The overall survival was 84.4%. Fluid adjustment was the only intervention associated with a decreased risk for starting KRT (OR 0.58, 95% CI 0.48-0.70, p = <0.001) and AKI progression to stage 3 (OR 0.59, 95% CI 0.49-0.71, p = <0.001). Receiving vasopressors and KRT were associated with mortality, but neither of these interventions reduced these risks. Conclusion In this prospective cohort study of AKI patients, we found for the first time that early nephrologist intervention and fluid prescription adjustment was associated with a reduction in the risk of starting KRT and progression to AKI stage 3.
