Diagnostic colonoscopy completion after abnormal fecal immunochemical testing and quality of tests used at eight Federally Qualified Heath Centers in Southern California: opportunities for improving screening outcomes

In a survey of 8 Federally Qualified Health Centers, among 1,229 patients with an abnormal fecal immunochemical test for colorectal cancer screening, 89% had referral, but just 44% completed diagnostic colonoscopy, with range of completion ranging 18 to 57% across health centers. The findings suggest a major need for policies and multi-level interventions to promote diagnostic colonoscopy among patients with abnormal colorectal cancer screening tests.
