How should I document the assessment and outpatient management plan for a patient with acute severe abdominal pain and red‑flag signs (sudden onset, guarding, rebound tenderness, fever, tachycardia, hypotension, vomiting, inability to pass flatus or stool, recent surgery or anticoagulation) who declines emergency department transport?

Documentation and Management of Acute Severe Abdominal Pain with ER Refusal

Immediate Documentation Requirements

Document the patient's refusal of emergency department evaluation explicitly, including your clear recommendation for immediate ER transport and the specific life-threatening risks you explained to the patient. 1, 2, 3

Critical Elements to Document

Assessment and Red Flags Present:

• Document all red-flag findings systematically: sudden onset pain, guarding, rebound tenderness (peritoneal signs), fever, tachycardia, hypotension, vomiting, inability to pass flatus or stool, recent surgery, and anticoagulation status 1, 2, 3

• Tachycardia is the most sensitive early warning sign of surgical complications and should be explicitly documented as indicating urgent surgical evaluation 3

• Pain out of proportion to physical examination findings must be documented as strongly suggestive of acute mesenteric ischemia until proven otherwise 1, 3

• The combination of fever, tachycardia, and tachypnea predicts serious complications including anastomotic leak, perforation, or sepsis 3

• Peritoneal signs (rigid abdomen, rebound tenderness) indicate perforation or ischemia requiring immediate surgical evaluation 2, 3

Specific Risks Explained to Patient

Document that you explained these specific life-threatening conditions:

• Bowel obstruction accounts for 15% of acute abdominal pain admissions and can progress to bowel necrosis, perforation, and death 1, 2

• Acute mesenteric ischemia carries 2-12% mortality that increases with every hour of delayed treatment 1, 4

• Perforated viscus can lead to sepsis and death without emergency surgical intervention 2, 3

• Hemodynamic instability (tachycardia, hypotension) suggests bleeding or sepsis requiring immediate resuscitation 2, 3

Documentation of Informed Refusal

Your documentation must include:

• Patient demonstrates decision-making capacity and understands the risks 1, 3
• Specific life-threatening diagnoses explained (bowel obstruction, mesenteric ischemia, perforation, sepsis) 1, 2
• Mortality risk of 2-12% with delayed treatment, increasing hourly 1, 4
• Patient verbalized understanding of these risks 3
• Patient signed against medical advice (AMA) form if available 3

Outpatient Management Plan (Against Medical Advice)

This plan is provided only because the patient refused appropriate ER evaluation, not because outpatient management is medically appropriate for this presentation. 1, 2, 3

Immediate Instructions

Return to ER immediately (call 911, do not drive) if any of the following occur:

• Worsening abdominal pain or new severe pain 2, 3
• Increasing abdominal distension 2, 3
• Persistent vomiting or inability to tolerate oral fluids 1, 2
• Fever above 38.5°C (101.3°F) 2, 3
• Dizziness, lightheadedness, or fainting (suggests bleeding or sepsis) 1, 2
• Bloody or black stools 3
• Inability to pass gas or stool for more than 12 hours 1, 2
• New confusion or altered mental status 1, 3

Monitoring Requirements

Patient must be monitored by a responsible adult continuously for the next 24 hours 1, 3

• Check vital signs every 2-4 hours (temperature, heart rate, blood pressure) 3
• Document any changes in pain character, location, or intensity 2, 3
• Monitor for signs of shock (rapid pulse, low blood pressure, cold/clammy skin) 1, 2

Medications and Restrictions

Do NOT take pain medications that could mask worsening symptoms 3, 4

• Avoid opioids and NSAIDs as they can obscure peritoneal signs and delay recognition of deterioration 3, 4
• Nothing by mouth except small sips of water until re-evaluated 1, 3
• Continue anticoagulation only if specifically instructed (document discussion of bleeding risk) 1

Mandatory Follow-Up

Patient MUST return to ER within 6-12 hours for re-evaluation if symptoms persist or worsen 1, 3, 4

• Earlier return mandatory if any red-flag symptoms develop 2, 3
• If unable to reach ER, call 911 for ambulance transport 1, 3

Critical Pitfalls to Avoid

Do not provide false reassurance—this presentation has high mortality risk without proper evaluation 1, 4

• Normal laboratory values do not exclude serious pathology, especially in elderly patients 2, 5
• Classic peritoneal signs may be absent despite established bowel ischemia or necrosis 3
• Every hour of delay in treating acute mesenteric ischemia increases mortality 1, 4
• Bowel obstruction can progress from simple to strangulated with necrosis within hours 1, 2

Document that outpatient management is contraindicated and provided only due to patient refusal of appropriate ER evaluation 1, 2, 3
