Hemoglobin Thresholds for Floor Admission in Upper Gastrointestinal Bleeding
Patients with UGIB can be safely admitted to the floor if they have a hemoglobin level greater than 100 g/L (10 g/dL), normal vital signs, and minimal comorbidities. 1
Risk Stratification for Floor vs. ICU Admission
Floor Admission Criteria:
- Hemoglobin >100 g/L (10 g/dL)
- Hemodynamically stable (pulse <100 beats/min, systolic BP >100 mmHg)
- Age <60 years (preferably)
- No significant comorbidities
- No active hematemesis
ICU/High-Dependency Unit Admission Criteria:
- Hemoglobin <100 g/L (10 g/dL)
- Hemodynamic instability (pulse >100 beats/min, systolic BP <100 mmHg)
- Age >60 years with comorbidities
- Active bleeding with shock
- Significant comorbidities (cardiac failure, renal failure, liver disease)
Transfusion Thresholds
The transfusion strategy should be guided by the following parameters:
- For most patients: Transfuse when hemoglobin <70-80 g/L (7-8 g/dL) 1, 2
- For patients with cardiovascular disease: Consider a higher threshold (e.g., 80-90 g/L) 1
- For actively bleeding patients with shock: Immediate transfusion regardless of hemoglobin level
The evidence strongly supports a restrictive transfusion strategy, as demonstrated in a landmark study by Villanueva et al. showing improved survival with a hemoglobin threshold of 70 g/L versus 90 g/L 2.
Risk Assessment Tools
The Rockall scoring system can help determine the risk of rebleeding and mortality:
| Total Rockall Score | Risk Level | Floor vs. ICU Decision |
|---|---|---|
| <3 | Low risk | Floor appropriate |
| 3-7 | Moderate | Floor with monitoring |
| >8 | High risk | ICU recommended |
Monitoring Requirements for Floor Patients
For patients admitted to the floor with UGIB:
- Hourly vital signs (pulse, BP)
- Urine output measurement
- Endoscopy within 24 hours
- IV access with fluid resuscitation as needed
- Serial hemoglobin measurements
Special Considerations
Coagulopathy
- Correction of coagulopathy is recommended but should not delay endoscopy 1
- Endoscopic treatment can be safely performed with INR <2.5
Elderly Patients
- Lower threshold for ICU admission
- More vigilant monitoring even with stable parameters
Liver Disease
- Special consideration required as prognosis relates to severity of liver disease rather than magnitude of bleeding 1
- May require specialized management protocols
Common Pitfalls to Avoid
- Relying solely on hemoglobin level: Initial hemoglobin may not reflect acute blood loss due to delayed hemodilution
- Overlooking tachycardia: A compensatory tachycardia may be the only sign of significant bleeding
- Underestimating comorbidities: Cardiac, renal, or liver disease significantly increases mortality risk
- Delaying endoscopy: Patients admitted to the floor still need timely endoscopy (within 24 hours)
- Inadequate monitoring: Even stable-appearing patients need regular vital sign checks
Algorithm for Admission Decision
- Assess hemoglobin level and vital signs
- Calculate Rockall score
- Evaluate comorbidities
- If hemoglobin >100 g/L, vital signs normal, and Rockall score <3: Floor admission
- If hemoglobin <100 g/L, abnormal vital signs, or Rockall score >8: ICU admission
- For intermediate cases: Consider high-dependency unit or floor with enhanced monitoring
This approach ensures that patients with UGIB are appropriately triaged based on their risk profile, optimizing resource utilization while maintaining patient safety.
