Adherence to colorectal cancer screening measured as the proportion of time covered.

ABSTRACT: BACKGROUND AND AIMS:Colorectal cancer (CRC) screening can reduce CRC incidence and mortality, but measuring screening adherence over time is challenging. We examined adherence using a novel measure characterizing the proportion of time covered (PTC) by screening tests. METHODS:Eligible patients were age 50 to 60 years and followed at a large, safety-net health care system between January 2010 and September 2014. We estimated PTC as the number of days up to date with screening divided by the number of days from cohort entry until study end, CRC diagnosis, or death. We estimated mean and median PTC and used least-significant difference tests to assess differences in adherence by patient characteristics. RESULTS:Of 18,257 patients, most were non-Hispanic black (40.5%) or Hispanic (34.9%) and/
