Age as a prognostic factor in acute renal failure (ARF). There is a tendency to treat elders with ARF less aggressively because of the presumed worse outcomes; however, prognosis may be similar to that found in the younger population. In the multicenter prospective longitudinal study in Madrid, relative risk for mortality in patients older than 80 years was not significantly different (1.09 as compared with 1 for the group younger than 65 years). Age probably is not a poor prognostic sign, and outcome seems to be within acceptable limits for elderly patients with ARF. Dialysis should not be withheld from patients purely because of their age.
