This is an iatroX educational summary of named Canada sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. Alberta is used as an explicit Canadian implementation example, not as a national rule. Verify the equivalent pathway, formulary and escalation route in the patient鈥檚 province or territory.

Alberta source: bounded use

The exact Alberta source is an adult general-surgery referral pathway, not a complete diverticulitis diagnosis, antibiotic or acute-treatment guideline. This summary is limited to referral readiness and excludes broader acute management.

Source-attributed clinical priorities

  • Use the Alberta referral pathway only after the acute presentation and diagnosis have been assessed through an appropriate local clinical pathway.
  • Send the pathway-required history, imaging, prior treatment and complication information with a referral for recurrent or complicated diverticular disease.
  • Distinguish routine referral from an unstable or acute surgical presentation that needs emergency assessment rather than the outpatient queue.
  • The linked Alberta document supports adult general-surgery referral and must not be cited for antibiotic selection or acute diverticulitis treatment.

Practical assessment and management workflow

1
Confirm the working diagnosis, course, prior episodes, prior treatment and whether an acute complication has already been excluded.
2
Gather the imaging, endoscopy and other documentation required by the current provincial referral route.
3
State the reason for surgical referral, relevant comorbidity, previous complications and effect on the patient rather than submitting a diagnosis label alone.
4
Track referral acceptance and deterioration while the patient waits and redirect acute change to emergency care.

Safety, red flags and urgent escalation

  • Peritonitis, sepsis, obstruction, major bleeding or inability to tolerate intake needs acute assessment, not routine referral.
  • Do not infer an antibiotic regimen, CT threshold or colonoscopy interval from this referral document.
  • A known history of diverticulosis does not establish that new acute pain is uncomplicated diverticulitis.

Confirm the local pathway before acting

Alberta is used as an explicit Canadian implementation example, not as a national rule. Verify the equivalent pathway, formulary and escalation route in the patient鈥檚 province or territory.

Source and implementation boundary

Read this educational summary with the linked source, current Canadian product information where medicines are involved, and the applicable provincial or territorial pathway. Local formularies, reporting duties, referral routes and service availability can differ.
