Colorectal screening in Canada, 2023-24
Innovations in colorectal screening
On this page:
The COVID-19 pandemic required jurisdictions to rethink how cancer screening services can be designed in a way that is responsive and resilient to future interruptions, demonstrates equitable access to screening services, and complies with health and safety measures. The Partnership made funding available in 2021 to support jurisdictions’ response to the pandemic through the Accelerating Innovations to Build Resilience in Cancer Screening during COVID-19 initiative. Four provinces and two territories participated in this initiative. These projects optimized existing programs and facilitated accelerated uptake of evidence-based innovation, thereby increasing resiliency of screening services through removing barriers to screening and improving access to colonoscopy services, particularly among underscreened populations.
Many jurisdictions continue to develop innovative solutions to ongoing challenges.
Results of the Accelerating innovations to build resilience in cancer screening during COVID-19 initiative
Yukon
The project supports purchasing colonoscopy equipment to improve procedure efficiency and quality, including improved infection control measures. Objectives include ensuring Yukon Hospital maximizes use of resources to better position themselves for current and subsequent waves of COVID-19 while improving sustainable CRC screening services and outcomes. The work is focused on ensuring that residents of Yukon, a jurisdiction with a large rural, remote, and First Nations population, have high quality and timely access to colonoscopy services.
Northwest Territories
The Northwest Territories project is focused on creating a proper database to facilitate ongoing Territorial Screening Programs for breast, colorectal, and cervical cancer. A functional database will allow a shift away from opportunistic testing towards inclusion methods that will more reliably serve under-screened populations, and experience less disruptions in local healthcare provision like those that have resulted from COVID-19.
Alberta
The FIT Mail-Out initiative aims to increase access to FIT kits via an alternate distribution process. A grant-funded project through the Canadian Partnership Against Cancer, it gives eligible Albertans the option to order a FIT kit online or over the phone. The kit is then mailed directly to the client’s home, effectively removing two visits to healthcare facilities: a healthcare provider for a requisition, and a lab for the kit itself.
Manitoba
ColonCheck participated in the Accelerating Innovations to Build Resilience in Cancer Screening during the COVID-19 initiative for CRC screening. Manitoba’s project provided a second CRC screening participation opportunity, inviting close to 15,000 residents due for screening. An FOBT was sent to specifically targeted individuals based on geography (low screening participation rates) and screening status (never screened or most overdue for screening), as well as to underserved populations that are unlikely to seek healthcare services during COVID-19 slow-down periods. Individuals who completed an FOBT through this project were incorporated into ColonCheck operations and integrated into the routine screening invitation cycle. Manitoba was pleased to see a participation rate that closely resembled program participation rate achieved during standard program recruitment strategies.
Quebec
This project’s objectives include validating the colonoscopy referral form, since a preliminary assessment no longer reflects current practice, including the current widespread use of FIT screening. It also aims to confirm that the nature and respective proportion of lesions discovered in a colonoscopy have not been affected by a change in patient characteristics during pre- and post-pandemic induced slowdown (e.g., when older patients at higher risk of colorectal cancer are not showing up for their colonoscopy for fear of contracting SARS-CoV-2 in a hospital setting). Quebec is also assessing the clinical benefits of increased yield and better wait time assignments via the colonoscopy referral form by allowing patients to select multiple indications (e.g., change in stool habits and rectal bleeding rather than only one or the other). An additional biological test that measures natural killer cell activity (NKViewTM) is being assessed to help further stratify patients with a positive FIT in assigning an adapted shorter wait-time for colonoscopies.
Prince Edward Island
The reinstatement of CRC screening during COVID-19 involved less in-person contact. This project aims to improve access and increase uptake in CRC screening. The Colorectal Cancer Screening Program implemented a direct-mail FIT kit, updated information materials, enhanced the program database with tracking and monitoring mailed FIT kits, and reviewed current data to include clients overdue for FIT screening since the pandemic. Internal office processes were reviewed and communicated to assemble kits, mail them to clients, and accept them in the centralized lab. This resulted in reduced traffic in health centres by unplanned visitors dropping off or requesting a FIT kit when restrictions were in place. During the pandemic, the supply chain was fragile. Receiving a kit in the mail and self-sampling at home were appreciated by participants.
The COVID-19 pandemic had a profound impact on health services across the country, including reducing or pausing cancer screening. Throughout the COVID-19 pandemic, and as screening programs resumed, many jurisdictions developed innovative tools and updated their processes to better serve the community.
Innovations in colorectal screening programs
Yukon
The biggest change to the program was the addition of telephone consults. This has decreased the abnormal FIT result to colonoscopy timeline.
Northwest Territories
The roll out of the new screening program had to be adjusted to avoid in-person gatherings. Community meal events planned as part of the program launch were replaced with radio ads, newspaper ads, etc.
Manitoba
ColonCheck CancerCare Manitoba partnered with Manitoba Health to expedite the transition to FIT (from gFOBT) to address the growing endoscopy waitlist caused by COVID-19. The initiative intended to decrease the number of patients waiting for a colonoscopy by diverting a specific eligible population (average risk, moderate increased risk, surveillance of low-risk adenomas) to FIT.
Ontario
In spring 2020, Ontario’s Ministry of Health paused all non-essential health services (e.g., cancer screening). This resulted in a pause in FIT kit mailing and some colorectal screening correspondence letters. A gradual approach was taken to resuming healthcare services (kit mailing resumed in summer 2020 and colorectal correspondence campaigns in winter 2020). Ontario Health (Cancer Care Ontario) continues to monitor screening trends and provide support to Regional Cancer Programs (RCPs) as needed.
Multiple tools that were developed include:
- Two tip sheets (COVID-19 Cancer Screening Tip Sheet for Primary Care Providers & COVID-19 Tip Sheet for Facilities Performing Gastrointestinal Endoscopy) providing evidence-based recommendations on prioritizing colorectal cancer screening during COVID-19.
- A COVID-19 Regional Monitoring and Planning Tool that is shared monthly with RCPs to help monitor COVID-19 recovery metrics (e.g., regional endoscopy backlog (currently retired), fecal test volumes, colonoscopy volumes and wait times for colonoscopy for people with an abnormal fecal test).
A media kit with materials (e.g., key messages, phone call scripts, program fact sheet, etc.) was also developed to support regional public awareness campaigns.
Since then, there have been no major changes to the ColonCancerCheck program in response to COVID-19.
Quebec
Implementing a funding system for endoscopy units improved volume and reduced wait times. This funding now includes an additional amount for colonoscopy overproduction to reduce the waiting lists that have increased during COVID-19. This program established the pairing of health institutions according to their proximity, wait times for colonoscopy, and capacity. When a balance is reached between supply and demand in colonoscopy in health institutions, the pairing and management of colonoscopy cases from partner institutions is mandatory. A call for tenders in endoscopy to promote access to clinics from the private sector helped to administer colonoscopy exams.
Nova Scotia
Nova Scotia Health’s Central Zone, the largest and most populous of the four management zones, has seen a complete change in how endoscopy is scheduled, with considerable effort to determine utilization of endoscopy time. When endoscopy services resumed in late May 2020 after a 12-week suspension, there were 800 people on the Central Zone FIT-positive wait list and estimated wait times of six to eight months. FIT-positive colonoscopy was prioritized. At the time of this report, two thirds of FIT-positive colonoscopies in the Central Zone have been completed within the target time-frame of eight weeks with a median wait time of six weeks.
The change has enabled Nova Scotia to re-envision how the program can be organized to support colon cancer screening more broadly. COVID-19 has provided an opportunity to have conversations about how Nova Scotia can maximize the existing infrastructure to do a better job ensuring all residents have access to appropriate screening.
Prince Edward Island
Before the direct-mail FIT kit project, people could only access drop-off locations at specific healthcare facilities. The pandemic resulted in restricted access to healthcare facilities. Rules were implemented, such as calling ahead before entering, meeting at the door restrictions, and not entering if symptomatic. If the participants were allowed to enter, they had to wear medical masks and undergo COVID-19 screening questions. The pandemic showed that providing service at drop-off locations was a weak point in the system.
The direct-mail initiative made it much easier for participants to receive and return the FIT kit. Participants mailed the kit to the central lab and did not need to go to a healthcare facility to drop the kit off. The direct-mail kit helped the healthcare system manage staff resources and protect staff and patients from potential contamination of COVID-19 infection carried by visitors. It also saved participants from in-person contact and potential COVID-19 contamination at healthcare facilities.
Newfoundland and Labrador
The Newfoundland and Labrador Colon Screening Program was well positioned to continue service through much of the COVID-19 pandemic as the program utilized the postal service to deliver and receive test kits. Additionally, FIT-positive colonoscopies received priority once follow-up service delivery could continue.
Jurisdictions are committed to continuous improvement of CRC screening programs. The priority work in each jurisdiction is presented below.
