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 as well as endoscopic finding. 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, 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 >100 BP >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 | - | Blood, adherent clot, spurting vessel |
