Table 4 Cost-effectiveness of 16 strategies of colorectal screening among Korean adults with raising reimbursement of colonoscopy to 60% higher than current level (Cost of colonoscopy = 85000 won1, NHI2 coverage = 50% screening compliance = 55%, follow-up compliance = 75%).

COL, colonoscopy; SIG, sigmoidoscopy; DCBE, double contrast barium enema; FOBT, fecal occult blood test. Current level of colonoscopy cost in Korea is about 53000 won.
1Exchange rate: 1200 Korean won for one US dollar.
2National Health Insurance of Korea.
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.
5Extended dominated: Extended dominated strategy is a strategy which is less effective and had a higher ICER than another strategy.
