Glasgow-Blatchford

Glasgow-Blatchford — upper gastrointestinal bleeding

Principle

Sum of contributions from urea, Hb using the male/female scoring system, SBP, pulse, melaena, syncope, liver disease and heart failure. Total 0–23.

Scope

Adult upper gastrointestinal bleeding, initial assessment before endoscopy. Original scoring system distinct from Rockall. No autonomous treatment or disposition decision.

Interpretation limits

The score helps assess the need for intervention. Disposition and endoscopy depend on clinical assessment and the chosen protocol; a low total does not authorise discharge.

Formula and logic

Sum of contributions from urea, Hb using the male/female scoring system, SBP, pulse, melaena, syncope, liver disease and heart failure. Total 0–23.
