Validation of a decision rule to predict patients at low risk of variceal upper gastrointestinal hemorrhage

Determining the likelihood of a variceal versus nonvariceal source of upper gastrointestinal bleeding (UGIB) guides ED therapy, but can be difficult to determine on clinical grounds. A simple decision rule, using only platelet and international normalized ratio (INR) values, was previously derived in a single center and had high sensitivity (97%). We sought to validate this decision rule using multi-center data.
