Healthcare costs, resource utilization, and productivity loss associated with colorectal cancer screening.

ABSTRACT

OBJECTIVES: To evaluate healthcare costs, resource utilization, associated costs, and lost productivity for colorectal cancer (CRC) screening in an average-risk population. METHODS: This retrospective cohort study identified average-risk individuals (50-75 years) with claims in the Optum Research Database for CRC screening test between 1 January 2014 to 31 December 2018. Index date was defined as the first date of a claim for colonoscopy, fecal immunochemical test (FIT), guaiac-based fecal occult blood test (FOBT) or multi-target stool DNA test (mt-sDNA). Screening costs were evaluated with descriptive statistics and multivariable analyses, adjusting for patient characteristics and index screening costs. RESULTS: In total, 903,831 individuals were identified by test groups mt-sDNA (n = 29,614), FIT (n = 254,002), guaiac-based FOBT (n = 112,757) and colonoscopy (n = 507,458). Adjusted costs for index screening were, colonoscopy ($3,029), mt-sDNA ($752), FIT ($45), and (FOBT ($153). Adjusted costs across the six months following the index screening were $146 for colonoscopy, $329 for mt-sDNA, $306 for FIT, and $412 for FOBT. Colonoscopy had the highest costs for lost productivity. CONCLUSIONS: Screening colonoscopy had the highest productivity loss and healthcare costs up-front, suggesting potential cost benefits for noninvasive screening modalities. The more frequent screening interval required for FIT and FOBT resulted in a higher yearly cost than colonoscopy or mt-sDNA.

Colorectal cancer (CRC) is a prominent healthcare concern the United States, which accounted for 149,500 new cases and 52,980 deaths in 2021. Screening is effective for diagnosing the condition at earlier more treatable stages, and reducing deaths. However, screening is largely underutilized in part due to perceived cost barriers. This observational study used insurance claims data to calculate healthcare costs, resource use, and lost productivity for CRC screening in an average-risk population aged 50­75 years. A total of 903,831 individuals were identified by test groups multi-target stool DNA test (mt-sDNA test; 29,614 individuals), fecal immunochemical test (FIT; 254,002 individuals), guaiac-based fecal occult blood test (FOBT; 112,757 individuals) and colonoscopy (507,458 individuals). Adjusted costs for initial screening were $3,029 for colonoscopy, $752 for mt-sDNA, $45 for FIT, and $153 for FOBT. Adjusted colonoscopy-related costs combined across the six months following the initial screening were $146 for the colonoscopy cohort, $329 for mt-sDNA, $306 for FIT, and $412 for FOBT. Colonoscopy had the highest costs for lost productivity. Overall, screening colonoscopy was accompanied by the highest productivity loss and up-front costs, suggesting potential cost benefits for noninvasive screening modalities ­ mt-sDNA, FIT, and FOBT; however, the more frequent screening interval required by FIT and FOBT resulted in a higher estimated average yearly screening cost.
