Figure 1:

Number of fecal immunochemical tests (FIT) completed, FIT results, number of colonoscopies, and cancer diagnoses among patients with ≥1 FIT completed in 2013–2014 and followed for 2 years from their baseline FIT. ^aInreach is the local distribution of FIT by primary care staff or otherwise. ^bInclusion criteria: 50–75 years of age; ≥2 years Kaiser Permanente membership prior to baseline FIT; no prior diagnosis of inflammatory bowel disease or CRC; no prior colectomy; and quantitative values available for all FITs during 2-year study interval. Patients followed for 2 years after the baseline FIT. ^c2-year time interval started at time of the baseline FIT. Overall, 80% of patients received a colonoscopy within 180 days of a positive FIT. ^d226,984 completed 2 additional FIT, 4,161 completed 3 additional FIT, and 153 completed 4 additional FIT during the 2-year follow-up. FIT: fecal immunochemical test, CRC: colorectal cancer
