Risk Stratification Scores for Upper GI Bleed Discharge Readiness
The Glasgow Blatchford Score (GBS) is the preferred prognostic tool for determining discharge readiness after upper GI bleeding, with a score of 0-1 identifying patients at very low risk who can be safely discharged without hospitalization or inpatient endoscopy. 1, 2
Primary Scoring System: Glasgow Blatchford Score
The GBS should be used as the primary risk stratification tool because it has superior sensitivity (99%) for identifying high-risk patients, meaning it misclassifies ≤1% of high-risk patients as low risk. 1, 2
GBS Components (Pre-Endoscopy)
The GBS includes only clinical and laboratory data available at presentation: 1, 2
- Hemoglobin level
- Blood urea nitrogen level
- Pulse rate
- Systolic blood pressure
- Presence of syncope
- Presence of melena
- Evidence of hepatic disease
- Evidence of cardiac failure
GBS Discharge Threshold
- A GBS score of ≤1 identifies patients at very low risk for rebleeding or mortality who may be safely discharged without hospitalization or inpatient endoscopy 2
- This threshold has excellent sensitivity (98.6%) for detecting high-risk patients 2
- Implementation of GBS-based early discharge reduces hospital admissions and healthcare costs without increasing adverse outcomes 1, 3
Alternative Scoring System: Rockall Score
The Rockall Score exists in two forms and has different utility: 1, 2
Pre-Endoscopic Rockall Score
- Has good sensitivity (93-96%) but may misclassify 4-7% of high-risk patients as low risk 1, 2
- Due to this lower sensitivity compared to GBS, international consensus groups could not make a firm recommendation for or against its use for discharge decisions 1
Complete (Post-Endoscopic) Rockall Score
- Requires endoscopic findings and is used post-endoscopy for comprehensive risk stratification 4, 2
- A complete Rockall score <3 indicates excellent prognosis with very low rebleeding and mortality risk 4
- Better discriminative ability for predicting mortality than rebleeding 1, 2
- Variables include age, shock parameters, comorbidities, endoscopic diagnosis, and stigmata of recent hemorrhage 4
Scoring System NOT Recommended: AIMS65
The AIMS65 score should NOT be used for discharge decisions because it was designed to identify high-risk patients for death rather than low-risk patients for safe discharge. 1, 2
- Even at low cutoff values, AIMS65 misclassifies approximately 20% of high-risk patients as low risk 1
- Has lower sensitivity (78-82%) for identifying high-risk patients compared to GBS 1
Additional Discharge Criteria Beyond Scoring
Clinical Parameters Required for Discharge
Beyond a low GBS score, patients must meet these criteria: 4
- Hemoglobin >100 g/L (10 g/dL) 4
- Normal vital signs: pulse <100 beats/min AND systolic blood pressure >100 mmHg 4
- Age <60 years (in most cases) 4
- Minimal or no comorbid conditions 4
Endoscopic Findings Permitting Discharge
Low-risk endoscopic findings that permit discharge include: 4
- Normal upper GI endoscopy
- Mallory-Weiss tear
- Peptic ulcer with clean base (no stigmata of recent hemorrhage)
- No evidence of varices or upper GI malignancy
Post-Endoscopy Observation
- A stabilization period of 4-6 hours post-endoscopy is necessary, during which pulse, blood pressure, and urine output are continuously monitored 4
High-Risk Findings That Preclude Discharge
Patients with these findings must be hospitalized: 4
- Age >60 years with other risk factors
- Pulse >100 beats/min
- Systolic blood pressure <100 mmHg
- Hemoglobin <100 g/L (10 g/dL)
- Significant comorbid medical diseases
- High-risk endoscopic findings: active bleeding from peptic ulcer, non-bleeding visible vessel, or adherent clot
Practical Implementation Considerations
When deciding on early discharge, consider these contextual factors: 1
- Urban versus rural environment
- Access to hospital or ambulance services
- Access to out-of-hours endoscopy
- Patient preferences regarding diagnostic certainty versus avoiding hospitalization
- Adequate social support and accessibility to hospital 4
Common Pitfalls to Avoid
- Do not use clinical judgment alone without a standardized scoring system, as this cannot be standardized and may lead to inconsistent risk assessment 1
- Do not discharge patients based solely on a low risk score without confirming hemodynamic stability and appropriate hemoglobin levels 4
- Do not use AIMS65 for discharge decisions, as its high false-negative rate makes it unsafe for this purpose 1
- Ensure appropriate therapy is initiated before discharge, including proton pump inhibitor therapy, H. pylori eradication when indicated, and NSAID counseling 4
