Endoscopist's Judgment Is as Useful as Risk Scores for Predicting Outcome in Peptic Ulcer Bleeding: A Multicenter...

Area of Science:

• Gastroenterology
• Clinical Medicine
• Medical Diagnostics

Background:

• Guidelines advocate prognostic scales for risk stratification in non-variceal upper gastrointestinal bleeding.
• The comparative accuracy of risk scores versus clinical judgment remains uncertain.
• Peptic ulcer bleeding (PUB) management benefits from accurate risk assessment.

Purpose of the Study:

• To compare the diagnostic accuracy of endoscopist judgment against established risk scores (Rockall, Glasgow-Blatchford, Baylor, Cedars-Sinai) for predicting outcomes in peptic ulcer bleeding.
• To evaluate the predictive performance for rebleeding and mortality.
• To assess the utility of current risk stratification tools in PUB management.

Main Methods:

• Prospective study of 401 patients with peptic ulcer bleeding (PUB) from February 2006 to April 2010.
• Endoscopist's subjective risk assessment for rebleeding and mortality recorded immediately post-endoscopy.
• Independent calculation of Rockall, Glasgow-Blatchford, Baylor, and Cedars-Sinai scores.
• Analysis using receiver-operating-characteristics (ROC) curves, sensitivity, specificity, and predictive values.

Main Results:

• Endoscopist's clinical judgment demonstrated areas under the ROC curve for rebleeding (0.67-0.75) and mortality (0.84-0.9).
• These values were comparable or superior to those of the studied risk scores.
• The findings held true for both the entire patient cohort and those undergoing endoscopic therapy.

Conclusions:

• Current risk scores for predicting rebleeding and mortality in peptic ulcer bleeding patients have moderate accuracy.
• Endoscopist's clinical judgment was not outperformed by existing risk scoring systems.
• Development of more precise prognostic scales is necessary for improved risk stratification in PUB.
