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.
ABSTRACT
Purpose: We partnered with a local Federally Qualified Health Center (FQHC) to test implementation of evidence-based interventions (EBI) promoting Fecal Immunochemical Test (FIT) CRC screening in an environment in which colonoscopy has been the prevailing screening strategy. We report on implementation adaptations and preliminary results. Background: Sociocultural and medical concerns are barriers to colonoscopy uptake in some populations. An additional barrier to CRC screening is system level capacity for colonoscopy that results in a back log of cases and long wait times. With Covid-19, the additional backlog in overdue CRC screening has underscored the need to expand FIT testing capacity to address screening needs and to pre-empt further racial/ethnic and SES disparities in CRC outcomes. This trial tests the unique and additive value of multiple EBIs for increasing CRC screening (primarily through FIT testing, but also colonoscopy when indicated) while evaluating the success of implementing these approaches. EBIs include the use of medical reminders, addressing the structural barriers (social determinants of health [SDOH]), and assistance from community health workers. Methods: Participants (3500), ages 45-75, were identified from a large FQHC in New Haven, CT and determined to be overdue for CRC screening. Participants were randomly assigned to one of the four arms of the study: 1) Provider reminder (overdue for CRC screening) only;2) Provider Reminder + SDOH short message and one-size-fits all link to resources;3) Provider Reminder + SDOH short message and offer for individualized navigation (trained navigators from local community) to address SDOH and other barriers;4) Provider Reminder + offer to participate in a CRC educational program as phase 2 of the NCI's Screen to Save program (not an EBI). Preliminary data on uptake of CRC screening will be presented. Results: With input from stakeholders, we have: 1) lowered age eligibility from 50 to 45 to align with new guidelines;2) expanded the target population to 2 additional satellite clinics, more than doubling the proposed study enrollment;3) incorporated design changes in the patient reminders. The collaboration between research team and clinician stakeholders has been critical in minimizing disruptions to clinical workflow while assuring fidelity to the evidence-based interventions. Preliminary outcomes (within one month of intervention) on uptake of intervention across the 4 arms of the study, i.e., referral for CRC screening and test completion will be presented. Conclusion: The unique challenges of this urban community of primarily African American/Black, Hispanic/Latinx and/or low socioeconomic status individuals stem from the disproportionate burden of SDOH barriers. Findings will inform primary care setting implementation of EBIs to address the anticipated increase in disparities in CRC screening, exacerbated by COVID-19 changes in health care access and utilization, as well as the increased demand associated with the change in guidelines.
