Yes, that's right. A colonoscopy is a technical procedure. Colonoscopies to screen for colorectal cancer shouldn't be performed solely by gastroenterologists. In some provinces and U.S. states, nurse practitioners perform colonoscopies, so other health care professionals can be called upon to provide support.
A colonoscopy is ordered further to a positive result from a fecal immunochemical test, which is an analysis to detect occult blood in stool. The individual has to see their doctor for the test to be ordered, and that delays the process. A lot of people don't have a family physician to send the test results to.
The Régie de l'assurance-maladie du Québec sends women 50 and over a letter asking them to undergo a mammogram to screen for breast cancer. The same approach could be used for colon cancer screening tests. Patients could be sent a prescription and asked to go to the pharmacy or a local community services centre, say, to pick up the kit to test for blood in the stool. The test results would then be analyzed, without the family physician having to be involved in the process. There is no reason why only the family physician can ensure that follow-up. All it would take is a test result management system to quickly refer patients to the appropriate health care professional.
