Figure 836

Prognosis in acute renal failure (ARF). This figure shows the utility of a prognostic system for evaluating the severity of ARF over time, using the experience of Turney [38]. He compared the age, mortality, and APACHE II score of ARF patients treated at one hospital between 1960 and 1969 and 1980 and 1989. In the latter period there were significant increases in both the severity of the illness as measured by APACHE II and age. Although there was a tendency to a higher mortality rate in the second period, this tendency was not great enough to be statistically significant.
