Partnering with primary care to implement evidence based interventions (EBI) to address overdue colorectal cancer (CRC) screening in Connecticut (CT)

ABSTRACT

PURPOSE: Partnering with the largest Federally Qualified Health Center (FQHC) in New Haven, CT, the goal is to implement and test 4 evidence-based interventions (EBI) to increase CRC screening, while evaluating real-world implementation. Here, we report on the six-month (approximate) follow up of a cohort of 3,127 patients overdue for CRC screening who received 1 or more EBIs in October 2021. BACKGROUND: Sociocultural and medical concerns are barriers to colonoscopy uptake contributing to disparities in CRC screening. An additional barrier is system level capacity. COVID-19 associated delays exacerbated the existing backlog of individuals overdue for CRC screening, underscoring the need to expand Fecal Immunochemical Testing (FIT) capacity. This was particularly evident in the safety-net primary care setting that serves lower socio-economic status individuals living in urban New Haven, CT. METHOD(S) We are testing the unique and additive value of multiple evidence-based interventions (EBIs) for increasing CRC screening. The EBIs include the use of medical reminders, addressing the structural barriers (social determinants of health [SDOH]), and providing assistance from community health workers (CHW). We randomized 3,127 patients overdue for CRC screening to one of 4 arms of the study. All individuals received a reminder from their providers that they were due/overdue for CRC screening with instructions to contact the FQHC. Arm 2 also included information on SDOH barriers, Arm 3 included this same information with offer of navigation from CHW/navigator;and Arm 4 included the offer of CHW educational video and support if needed. Six-month (approximate) outcomes include 1) Engagement with FQHC resulting in ordered test;2) completed test. Results by intervention will be assessed at 12 months. RESULT(S) Of the 3,127 randomized patients, ages 50-75, 77% were Hispanic (33%) or Black (44%). At 6+ months, a preliminary look at EMR data show that a minimum of 1,275 (40.8%) patients "engaged" with providers resulting in an ordered FIT Kit (n= 1174) or COMPLETED screening colonoscopy that was not associated with a positive FIT result (n = 102). 217 (18.5%) individuals completed the FIT testing with 13 requiring confirmatory colonoscopy (31% completed at this time). Thus, a minimum of 319 (10%) of 3,127 individuals in the cohort completed CRC screening at approximately 6 months post intervention. DISCUSSION: Despite investments in community engagement, stakeholder input, and FIT kit capacity building, the pandemic presented unforeseen challenges. Flexibility and steadfast commitment from FQHC providers and staff were critical to successful implementation during multiple waves of COVID-19, resulting in CRC screening ordered for 41% of cohort within 6 months of intervention. SUMMARY: At 6 months follow up of 3,127 individual who were overdue for CRC screening, one or more of 4 EBIs, in addition to system level efforts to address CRC screening, resulted CRC screening tests ordered for 41% of cohort with at least 10% completed screening.
