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

To evaluate healthcare costs, resource utilization, associated costs, and lost productivity for colorectal cancer (CRC) screening in an average-risk population.

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.

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.

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.
