Impairment of renal function in medical intensive care: predictability of acute renal failure.
Acute causes and chronic risk factors for the development of acute renal failure were analyzed in prospective acquired data of 261 patients in a medical ICU. The population was divided into a group requiring dialysis treatment for established renal failure (n = 95) and a collective maintaining mild renal insufficiency (n = 166). Bivariate and linear discriminant analyses revealed that, above all, variables related to bacterial infections (sepsis and administration of antibiotic agents) and pancreatitis contributed to the discrimination, followed by bleeding, volume depletion, and chronic liver disease in the discriminant function. Bivariate analysis also yielded significant results for mechanical ventilation, CNS depression, and surgery. The importance of the nephrotoxic properties of aminoglycosides may be outweighed by their role as an indicator of severe infectious disease. The overall correct classification rate of the discriminant function was 78.5%, which reflects the importance of the predictor variables, but does not allow individual predictions.
