Glasgow-Blatchford Score
The Glasgow-Blatchford Score (GBS – table 1) is the risk assessment tool of choice in the emergency department. [8]
It is calculated using 4 components – medical history (hepatic disease, heart failure), symptoms (melaena, syncope), signs (tachycardia, blood pressure), and blood tests (haemoglobin, urea).
An online score calculator is ideal to use as individual components can have values between 0 and 6. The maximum score is 29.
NICE recommends that patients with a GBS of 0 can be considered for early discharge with outpatient endoscopy follow up. [1]
The British Society of Gastroenterology consensus statement extends this to patients with a GBS of 0 or 1. [9]
