Colorectal cancer screening rates are important metrics for public health and quality indicators for health care systems; however, published estimates of colorectal cancer screening rates often include both high-risk and average-risk patients, and the use of different epidemiologic methods makes between-study comparisons tenuous. The objective of this study was to measure the proportion of average-risk American adults who are up to date with colorectal cancer screening guidelines and examine the impact of evaluation methods on screening rate estimates. This repeated cross-sectional study used administrative claims to identify individuals aged 50-75 years between 2015 and 2018 with ≥ 1-year of continuous health plan enrollment.
