Liano et al developed a discriminant score for predicting the outcome of a patient with acute tubular necrosis. The authors are from Hospital Ramon y Cajal and Universidad Complutense in Madrid, Spain.
Parameters:
(1) oliguria present when the patient is first seen by the nephrologist
(2) deep neurologic coma
(3) peristent systolic hypotension
(4) assisted respiration (on a ventilator)

where:
• These correspond to multi-organ failures.
discriminant score =
= (0.94 * (points for oliguria)) + (0.14 * (points for assisted respiration)) + (0.20 * (points for hypotension)) + (0.266 * (points for deep coma)) + 0.251
Interpretation:
• minimum score: 0.251
• maximum score: 1.797
• The higher the score the worse the prognosis.
