Patients with abnormal FIT results are navigated to complete a diagnostic colonoscopy.

Mailed invitations for FIT test kits: Mailed invitations for the non-invasive immunochemical stool blood test will be the intervention compared to the standard care at John Peter Smith Hospital. Patients will be invited to complete a free home-based, non-invasive immunochemical stool blood test.

Mailed Invitations for a Colonoscopy

Invitation to schedule a colonoscopy are mailed to patients' homes for free colorectal cancer screening.

Intervention: Screening for colorectal cancer with colonoscopy. Mailed invitation to complete one free colonoscopy. Automated and live phone reminders to promote screening completion, plus usual medical care.

Patients with abnormal polyps or adenomas will follow standard clinical protocol after their procedure.

Mailed invitations for a colonoscopy: These patients will be mailed invitations to directly book a free colonoscopy, or to see a physician for free pre-operative screening at John Peter Smith Hospital.

Visit Based Care

No invitation to complete colorectal cancer screening.

Intervention: Usual medical care. Patients will continue to see their regular physician, and follow their physician's regular standard of care.

Visit Based Care: Visit based standard care at John Peter Smith Hospital. Patients will continue to see their regular physician and follow the physician's recommendations as they normally would.
