Canterbury Endoscopy & Gastroenterology — Clinical Tool (Prototype)
Logic per Te Whatu Ora, Jul 2023

Family History of Colorectal Cancer
Risk Stratification Tool

Family map
Answer the questions to build a picture of the reported family history.
Prototype decision-support aid for point-of-care use (e.g. general practice or referral triage). It reflects the logic of Update on Surveillance Recommendations for Individuals with a Family/Whānau History of Colorectal Cancer (Te Whatu Ora — Health New Zealand, July 2023) and does not replace clinical judgement. Scenarios outside the scope of the published categories are flagged rather than guessed at. For patients aged over 75 or with significant comorbidities, weigh the benefits and risks of any surveillance individually. Not for use as a sole determinant of clinical care.
