Abdominal pain initial triage
Primary care framework for abdominal pain risk stratification, early safety checks, and disposition planning.
Last reviewed February 7, 2026
Red flags
- Immediate ED assessment for peritoneal signs, sudden severe pain or pain disproportionate to the examination, even with normal vital signs.
- Hemodynamic instability, syncope, GI bleeding, or inability to maintain hydration.
- Pregnancy-related pain/bleeding concern requiring urgent obstetric pathway.
Assessment priorities
- Clarify pain location, onset pattern, progression, and associated systemic symptoms.
- Check pregnancy risk where relevant and review medication or substance triggers.
- Perform focused exam for peritoneal signs, dehydration, and hemodynamic instability.
Initial management
- Use early risk stratification to separate outpatient workup from urgent escalation.
- Start symptom-guided supportive management while narrowing differential diagnosis.
- Document clear escalation thresholds if diagnostic uncertainty remains.
Follow-up and escalation
- Arrange a specific reassessment appointment when diagnosis is provisional; worsening symptoms should not wait for it.
- Escalate to urgent imaging or emergency assessment for worsening trajectory.
- Reinforce return precautions for fever, persistent vomiting, bleeding, or new instability.
