Severe Clostridioides difficile infection

Recognise severe or fulminant C. difficile infection, isolate promptly and coordinate antimicrobial, surgical and critical-care decisions.

PAUSE BEFORE USING

This is an educational summary, not a point-of-care protocol. Follow current local emergency and medicines guidance and seek senior/specialist support.

FICTIONAL SCENARIO

A fictional inpatient develops frequent diarrhoea, abdominal pain, fever, rising white-cell count and worsening renal function after broad-spectrum antibiotics.

01 · RECOGNISE

Frame the danger first.

  • New diarrhoea after healthcare exposure or antibiotics warrants infection-control and diagnostic consideration.
  • Systemic toxicity, severe abdominal pain, distension or organ dysfunction suggest severe disease.
  • Ileus can occur in severe disease and may reduce stool output rather than reassure.
02 · FIRST PRIORITIES

Act, escalate, reassess.

  1. Isolate and initiate local infection-prevention measures promptly.
  2. Assess ABCDE, hydration, abdominal signs, organ function and alternative causes of deterioration.
  3. Use current local microbiology/antimicrobial guidance and seek early infection, gastroenterology and surgical advice for severe disease.
  4. Monitor for toxic megacolon, perforation, shock and need for critical care.
03 · ESCALATE NOW IF

Red flags that change pace.

  • Hypotension, rising lactate, acute kidney injury or altered mental state
  • Abdominal distension, peritonism, ileus or escalating pain
  • Rapidly worsening inflammatory markers or failure to respond to treatment
04 · COMMON ERRORS

What makes care less safe.

  • Treating diarrhoea alone without assessing severity
  • Missing ileus as a severe-disease presentation
  • Delaying surgical discussion in a deteriorating patient
05 · STRUCTURED HANDOVER
