rockall score rockall score rockall risk scoring system attempts to identify patients at risk of adverse outcome following acute upper gastrointestinal bleeding. rockall et al. identified independent risk factors in 1996 which were later shown to predict mortality accurately. the scoring system uses clinical criteria (increasing age, co-morbidity, shock) as well as endoscopic finding (diagnosis, stigmata of acute bleeding). it is named for professor tim rockall, who was the main investigator and first author of the studies that led to its formulation. a convenient mnemonic is abcde - i.e. age, blood pressure fall (shock), co-morbidity, diagnosis and evidence of bleeding. variable score 0 score 1 score 2 score 3 age <60 60- 79 >80 shock no shock pulse >100bp >100 systolic sbp <100 co-morbidity nil major chf, ihd, major morbidity kidney failure, liver failure, metastatic cancer diagnosis mallory-weiss all other diagnoses gi malignancy evidence of bleeding none blood, adherent clot, spurting vessel rockall scoretest ofassess after gi bleeding(for adverse outcome) interpretation total score is calculated by simple addition. a score less than 3 carries good prognosis but total score more than 8 carries high risk of mortality.
