Predicting poor outcome from acute upper gastrointestinal hemorrhage.

In conclusion, numerous prediction models identified pre-endoscopic and endoscopic risk factors for adverse clinical outcomes in patients with acute upper GI hemorrhage. The risk factors for mortality are different from those of rebleeding. Predictors for rebleeding are usually related to the severity of the bleeding and characteristics of the ulcer, whereas advanced age, physical status of the patient, and comorbidities are important predictors for mortality in addition to those for rebleeding. Future studies should focus on validation of these predictors in a prospective cohort and application of these prediction models to guide clinical management in patients with acute upper GI hemorrhage.
