Ways of estimating prognosis in acute renal failure (ARF). This can be done using either general intensive care unit (ICU) score systems or methods developed specifically for ARF patients. ICU systems include Acute Physiological and Chronic Health Evaluation (APACHE) [21,22], Simplified Physiologic Score (SAPS)[23,24], Mortality Prediction Model (MPM) [25,26], and Organ System Failure scores (OSF) [27]. Multiple Organ Dysfunction Score (MODS) [28] and

Sepsis-Related Organ Failure Assessment Score (SOFA) [29] are those that seem most suitable for this purpose. APACHE II used to be most used. Other systems (white boxes) have been used in ARF. On the other hand, at least 17 specific ARF prognostic methods have been developed [20,30]. The figure shows only those that have been used after their publication [31], plus one recently published system which is not yet in general use [2].
