Pathway Overview

Algorithm Steps

17 total

  1. 01Start

    START: Suspected UGIB

    Hematemesis, melena, or coffee-ground emesis

  2. 02Action

    Initial Resuscitation

    Stabilize before risk stratification

    • 2 large-bore IVs (≥18G)
    • Type and screen/crossmatch
    • CBC, BMP, coags, LFTs
    • NPO status
    • Continuous monitoring
  3. 03Decision

    Hemodynamically Stable?

    Assess vital signs and perfusion

    • UNSTABLE: SBP <90, HR >100, orthostatic changes, signs of shock
    • STABLE: Normal vitals, no orthostatic changes
  4. 04Warning

    Aggressive Resuscitation

    Hemodynamic instability

    • Crystalloid bolus
    • Blood transfusion (target Hgb ≥7, or ≥8 if CAD)
    • Consider massive transfusion protocol if ongoing bleeding
    • Correct coagulopathy (FFP if INR >1.5, platelets if <50K)
    • Early GI and surgical consult
  5. 05Action

    IV PPI Therapy

    Start before endoscopy

    • IV PPI bolus: Pantoprazole 80mg or equivalent
    • Followed by continuous infusion 8mg/hr (for high-risk stigmata)
    • OR intermittent high-dose (80mg q12h) if low-risk stigmata
    • Continue until endoscopy determines risk
  6. 06Action

    Consider Erythromycin

    Prokinetic before EGD

    • Erythromycin 250mg IV 20-90 min before EGD
    • Improves visualization
    • Reduces need for repeat endoscopy
    • Conditional recommendation
  7. 07Decision

    EGD Timing

    Based on stability and risk

    • URGENT (<12 hr): Hemodynamically unstable, ongoing bleeding
    • EARLY (12-24 hr): High-risk patients (GBS ≥12, liver disease)
    • STANDARD (<24 hr): All other admitted patients
  8. 08Action

    Upper Endoscopy (EGD)

    Diagnostic and therapeutic

    • Identify bleeding source
    • Forrest classification for ulcers
    • Endoscopic therapy if high-risk stigmata
    • Combination therapy preferred (epinephrine + thermal/clip)
  9. 09Decision

    Forrest Classification

    Ulcer stigmata risk

    • HIGH-RISK (treat): Ia (spurting), Ib (oozing), IIa (visible vessel), IIb (adherent clot)
    • LOW-RISK (no treatment): IIc (flat spot), III (clean base)
  10. 10Action

    High-Risk Stigmata

    Endoscopic therapy required

    • Combination therapy: Epinephrine injection + thermal/clips
    • High-dose IV PPI infusion x 72 hours post-EGD
    • NPO initially, advance diet as tolerated
    • Monitor for rebleeding
  11. 11Warning

    Rebleeding?

    Signs of recurrent hemorrhage

    • Hematemesis or melena recurrence
    • Hemoglobin drop >2g despite transfusion
    • Hemodynamic instability
  12. 12Action

    Repeat EGD vs IR/Surgery

    Manage rebleeding

    • Repeat EGD for second attempt at hemostasis
    • Interventional radiology (angioembolization) if EGD fails
    • Surgery if IR unavailable or fails
  13. 13Outcome

    Discharge Planning

    After successful management

    • Test and treat H. pylori if ulcer
    • Review and stop NSAIDs if possible
    • PPI for 8-12 weeks (longer if on anticoagulation)
    • GI follow-up
    • Discuss anticoagulation/antiplatelet resumption with cardiology
  14. 14Action

    Low-Risk Stigmata

    Medical management

    • No endoscopic therapy needed for IIc/III
    • Oral PPI daily
    • Early feeding (within 24 hr)
    • Early discharge if stable
  15. Path rejoins step 13Shared downstream outcome
  16. 15Action

    Risk Stratification

    Calculate Glasgow-Blatchford Score (GBS)

    • BUN, Hemoglobin, SBP, HR, Melena, Syncope, Liver disease, Heart failure
    • GBS = 0-1: Very low risk, may consider outpatient management
    • GBS ≥1: Admit for inpatient management
  17. 16Decision

    GBS 0-1?

    Very low risk patients

  18. 17Outcome

    Consider Outpatient EGD

    GBS 0-1 may be discharged

    • Oral PPI twice daily
    • EGD within 24-72 hours as outpatient
    • Clear return precautions
    • Reliable patient with good support
  19. Path rejoins step 05Shared downstream outcome

Clinical Decision Support — Not a Substitute for Clinical Judgment

Individual patient factors may require deviation from these recommendations.

Known Limitations

  • Does not address variceal bleeding in detail (separate algorithm)
  • Risk scores should be calculated formally
  • Endoscopy timing varies by local resources
  • PPI dosing may vary by institution
  • Transfusion triggers are general - individualize for comorbidities
