Colorectal cancer (CRC) is among the most common cancers and causes of cancer-related deaths in the United States.1 Reflective of a nationwide trend, CRC screening rates at the Veterans Affairs Connecticut Healthcare System (VACHS) decreased during the COVID-19 pandemic.2-5 Contributing factors to this decrease included cancellations of elective colonoscopies during the initial phase of the pandemic and concurrent turnover of endoscopists. In 2021, the US Preventive Services Task Force lowered the recommended initial CRC screening age from 50 years to 45 years, further increasing the backlog of unscreened patients.6
Fecal immunochemical testing (FIT) is a noninvasive screening method in which antibodies are used to detect hemoglobin in the stool. The sensitivity and specificity of 1-time FIT are 79% to 80% and 94%, respectively, for the detection of CRC, with sensitivity improving with successive testing.7,8 Annual FIT is recognized as a tier 1 preferred screening method by the US Multi-Society Task Force on Colorectal Cancer.7,9 Programs that mail FIT kits to eligible patients outside of physician visits have been successfully implemented in health care systems.10,11
The VACHS designed and implemented a mailed FIT program using existing infrastructure and staffing.
Program Description
A team of local stakeholders comprised of VACHS leadership, primary care, nursing, and gastroenterology staff, as well as representatives from laboratory, informatics, mail services, and group practice management, was established to execute the project. The team met monthly to plan the project.
The team developed a dataset consisting of patients aged 45 to 75 years who were at average risk for CRC and due for CRC screening. Patients were defined as due for CRC screening if they had not had a colonoscopy in the previous 9 years or a FIT or fecal occult blood test in the previous 11 months. Average risk for CRC was defined by excluding patients with associated diagnosis codes for CRC, colectomy, inflammatory bowel disease, and anemia. The program also excluded patients with diagnosis codes associated with dementia, deferring discussions about cancer screening to their primary care practitioners (PCPs). Patients with invalid mailing addresses were also excluded, as well as those whose PCPs had indicated in the electronic health record that the patient received CRC screening outside the US Department of Veterans Affairs (VA) system.
