Introduction: Colorectal cancer (CRC) screening is a critical preventative service and part of routine patient care. CRC is the second leading cause of cancer death in the US, and yet a third of the eligible population does not undergo routine screening. Endoscopy centers have been stretched thin by both COVID-19 and the recent drop in screening initiation age to 45. Fecal immunochemical testing (FIT), a sensitive and specific CRC screening modality, may be used to reach and risk-stratify more patients to increase the yield for detecting advanced neoplasia and cancer, reducing pressure on colonoscopy centers. Unfortunately, FIT is often suboptimal as patients inconsistently complete and return the test for analysis.

Methods: We performed a retrospective analysis of 5211 individuals at a single internal medicine clinic who had FIT ordered as part of USPSTF recommended care from 01/2017 through 12/2021. Starting in 01/2021 we instituted a dedicated patient navigator to support patients in completing FIT. Chi-square, Fisher exact test, and Student’s t-tests were performed for descriptive analyses. Multivariable logistic regression was used to compare FIT kit drop off rates pre- and post-intervention, with the model adjusted by age, gender, race, ethnicity, language, and insurance status. Analysis was performed in SAS version 9.4.

Results: The post-intervention period included 1181 (22.7%) patients. The predominant reasons cited for failure to complete testing were “forgot” (25%), “too busy” (13%), and “lost kit” (11%). Our intervention improved drop off rates from 46.4% to 51.3% at 2 weeks (OR 1.19, 95%CI 1.01-1.41), 56.7% to 73.7% at 1 month (2.14 [1.78-2.58]), 64.7% to 89.7% at 3 months (4.73 [3.66-6.12]), and 78.9% to 98.2% at 1 year (14.39 [8.25-25.12]). Overall, our intervention improved FIT kit drop off rates by 53.4% (1.53 [1.30-1.81]). FIT was positive in 4.9% (p=0.0529).

Discussion: FIT can increase CRC screening rates, particularly in resource-limited settings, and may decrease the burden on endoscopy centers nationwide by improving the efficiency of colonoscopy in the average risk screening population. The addition of a dedicated patient navigator is a simple intervention that, by providing culturally competent care and personalized attention, improves completion rates and return time, allowing FIT to be a reliable method of screening. The ability to increase screening rates and prioritize patients for diagnostic colonoscopies will ultimately lead to earlier detection and treatment of CRC.
