The Glasgow Alcoholic Hepatitis Score (GAHS) is a validated 5-variable clinical scoring tool for predicting 28-day and 84-day mortality in patients with severe alcoholic hepatitis. Developed by Forrest et al. (2005) at Glasgow Royal Infirmary, GAHS uses age, white cell count, blood urea nitrogen, prothrombin time ratio, and serum bilirubin. A score ≥ 9 identifies patients likely to benefit from corticosteroid therapy, and GAHS has been shown to be superior to Maddrey Discriminant Function for predicting steroid benefit.
