Feasible economic strategies to improve screening compliance for colorectal cancer in Korea

Table 2 Cost-effectiveness of 16 strategies of colorectal screening among Korean adults without NHI coverage (NHI^a coverage = 0%, screening compliance = 30%, follow-up compliance = 50%).

COL, colonoscopy; SIG, sigmoidoscopy; DCBE, double contrast barium enema; FOBT, fecal occult blood test. Ellipses indicate no data (incremental days or life gained and incremental CE ratio were not calculated for these strategies because they were dominated or extended dominated).

²Exchange rate: 1200 Korean won for one US dollar.

³Incremental CE ratio (won/year) = Incremental cost per person/Incremental days of life gained×365 d.

⁴Dominated strategy is a strategy that is more or equally costly and less effective than a competing strategy.
