APACHE score. The APACHE II score is not a good method for estimating prognosis in acute renal failure (ARF) patients. A, Data from Verde and coworkers show how mortality was higher in their ICU patients with ARF needing dialysis than in those without need of dialysis, despite the fact that the APACHE II score before dialysis was equal in both groups [39]. B, Similar data were observed by Schaefer's group [40], who found that the median APACHE II score was similar in both the surviving or nonsurviving ARF patients treated in an intensive care unit. Recently Brivet and associates have found that APACHE II score influences ARF prognosis when included as a factor in a more complex logistic equation [2]. Although not useful for prognostic estimations, APACHE II score has been used in ARF for risk stratification.
