Infection-related treatment*
Per-procedure cost at different infection rates: 1.6/10001 and 0.37/1004 | 20.12– 46.52 | Not for infections caused by endoscopic cross-contamination | ||
| Total | ||||
| 10 colonoscopes | 357.66–384.07 | 205.08–231.49 | 154.23–180.63 | |

Costs marked with bold font are the base-case numbers (ie, based on 20 colonoscopes). The message of this study is based on the base-case results. Other estimates are used to increase transparency and to make data comparable to other facilities.
