Synopsis
Use physiology and validated pre- and post-endoscopy scores to identify low-risk discharge, prioritise resuscitation and endoscopy, and communicate the continuing risk of rebleeding accurately.
- Use Glasgow-Blatchford before endoscopy and full Rockall afterwards. For a 68-year-old with presenting pressure 104 mmHg, pulse 108, no major comorbidity and a duodenal-ulcer visible vessel, full Rockall is age 1 + shock 1 + comorbidity 0 + diagnosis 1 + stigma 2 = 5.
- GBS combines urea, sex-specific haemoglobin, pressure, pulse and clinical features: melaena adds one point and syncope two; hepatic disease and cardiac failure each add two. Use exact thresholds rather than an estimated low score.
- NICE considers early discharge at GBS 0; ESGE 2026 identifies GBS 0–1 as very low risk for outpatient management. Both need a stable patient, no separate admission need and safe investigation, follow-up and return arrangements.
Key red flags
Haemodynamic instability, ongoing red haematemesis, syncope, rising lactate or reduced consciousness indicates dangerous bleeding even before haemoglobin falls.
A low numerical score is valid only when every component is correctly measured and the patient has no separate reason for admission or urgent investigation.
Tachycardia, hypotension, cool peripheries, confusion and oliguria indicate reduced circulating volume and demand immediate treatment.
Reasoning priorities
Estimate intervention need at first presentation before endoscopy.
Calculate from contemporaneous urea, sex-specific haemoglobin, systolic pressure, pulse and clinical features; NICE early-discharge consideration is score 0. Syncope scores two and melaena one; use the complete threshold table in the summary, rather than estimating low risk from normal blood pressure alone.
Worked reasoning
A 31-year-old man has one small self-limited haematemesis after retching, pulse 82, systolic pressure 126 mmHg, urea 5.4 mmol/L and haemoglobin 146 g/L, with no melaena, syncope, liver disease or cardiac failure.
- Confirm airway safety, stable serial observations, no ongoing bleeding, benign abdominal examination and no anticoagulant exposure before using a score to support disposition.
- Enter each value and clinical feature: all Glasgow-Blatchford components score zero, producing a documented total of 0 rather than an estimated low score.
- After senior review, consider early discharge under NICE guidance with an arranged follow-up investigation and explicit return instructions for recurrent blood, melaena, fainting or weakness.
- Verify next-day contact: there has been no further bleeding, oral fluids are tolerated and the booked endoscopy or clinic plan is visible to both patient and receiving service.
