Evaluating the Cost-Effective Use of Follow-Up Colonoscopy Based on Screening Findings and Age

Table 6

Recommended follow-up colonoscopy intervals by colonoscopy screening age and screening colonoscopy results.

Screening colonoscopy age and results	Recommended follow-up interval	Range of cost-effective follow-up colonoscopy	Gain in QALYs/10,000 persons for recommended follow-up interval
$100,000/QALYs gained threshold
50 years
All findings	8.5 years	7.7–20 years	84.0
No neoplasia	8.5 years	7.6–20 years	84.0
1 to 2 nonadvanced adenomas only	8.5 years	7.4–20 years	84.0
3+ nonadvanced adenomas only	9.0 years	7.8–20 years	83.3
1 to 2 adenomas with some advanced neoplasia	8.4 years	8.2–20 years	81.3
3+ adenomas with some advanced neoplasia	8.9 years	8.4–20 years	80.7
