Abstract

This systematic review examined factors associated with overuse of colorectal cancer (CRC) screening. The authors searched MEDLINE and EMBASE from January 1998 to March 2017. Studies were included if they were written in English, contained original data, involved a US population, and examined factors potentially associated with overuse of CRC screening. Paired reviewers independently screened abstracts, assessed quality, and extracted data. In 8 studies, the associations between patient factors, including age, sex, race, and number of comorbidities, were tested and were inconsistently associated with CRC screening overuse. Overuse of screening was greater in the Northeast/Mid-Atlantic regions and in urban areas and was lower in academically affiliated centers. Although the literature supports important overuse of CRC screening, it remains unclear what drives these practices. Future research should thoroughly explore these factors and test the impact of interventions to reduce overuse of screening.
