The Effect of Age on the Effectiveness (A), Costs (B), and Cost Effectiveness (C) of Colonoscopy Screening: Results for Average Risk Individuals with a Negative Screening Colonoscopy 10 Years Prior and No Comorbidities (QALYs gained and costs per 1,000 individuals; 3% discounted).1

QALY = quality-adjusted life-year

1Detailed results on the effectiveness and costs of screening can be found in Appendix 3.

2The effect of screening on quantity and quality of life incorporated in one measure (i.e. the net health benefit of screening). A negative value indicates that screening is associated with a net harm, rather than a net health benefit.

3The costs of screening and surveillance colonoscopies, complications of colonoscopy, and overtreatment of CRC minus the savings associated with preventing CRC treatment.
