This industry-sponsored study examined adherence rates to the fecal immunochemical test (FIT)-fecal DNA test commercially available from Exact Sciences Laboratories. The authors were all associated with the company.
Between September 1, 2016, and August 31, 2017, there were 368,494 Medicare patients (64% female) who had the test ordered, and 71% completed the test. The test was ordered by primary care physicians (PCPs) in 88% of the instances, gastroenterologists in 6%, and other specialists in the remainder. The adherence rate was lower when ordered by PCPs compared to gastroenterologists (71% vs 78%).
