The Glasgow Blatchford Score (GBS)

The Glasgow Blatchford Score (GBS) is a pre-endoscopic risk assessment tool for patients presenting with upper gastrointestinal haemorrhage (UGIH). It can predict need for intervention or death and identifies low risk patients suitable for out-patient management.

A score of 0 identifies low-risk patients.

Low-risk criteria of GBS

  • Urea <6·5 mmol/L
  • Haemoglobin >/=13 g/dl (men) or >/=12 g/dl (women)
  • Systolic blood pressure >/=110 mm Hg
  • Pulse <100 beats per min
  • Absence of melaena, syncope, cardiac failure, or liver disease
