RESUMO
Colorectal cancer (CRC) is a leading cause of mortality in the United States. Outcomes are greatly improved if CRC is detected early; hence, screening is currently recommended for adults aged 45 years and older at average risk for the disease. Despite this recommendation and the availability of accurate screening tests, the CRC screening rates are below those recommended. The goal of this study was to identify temporal trends (from 2015 to 2019) in CRC screening rates and the utilization of screening tests recommended for CRC detection among average-risk individuals within the St Elizabeth Healthcare system in Kentucky, United States. The primary population of interest was patients aged 50-75 years (the CRC screening was recommended for this age group at the time of the study). Deidentified data were sourced from patients' electronic health records, and the results showed that screening rates increased significantly from 26% in 2015 to 49% in 2019 (<0.0001). The incidence of any screening test also increased significantly from 2015 to 2019, for those who were due for screening (P < 0.05) and for the entire cohort (P < 0.1). The use of multitarget stool DNA (mt-sDNA) increased 40-fold over the study timeframe (P < 0.05). These study results confirm that CRC screening rates remain suboptimal, although incidence and adherence improved significantly in those aged 50-75 years from 2015 to 2019. The growing adoption and availability of mt-sDNA may be correlated with an increase in overall screening in this average-risk population.
