Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary aims 1) Number of training rounds needed to reach clinically acceptable prediction of histology (accuracy > 90%) for colorectal lesions 2) To assess whether qualified endoscopists are able to maintain this performance over a year, and if feedback is of additional value | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary aims: 1) number of endoscopists reaching NPV > 90% for predicting neoplastic histology in continuation phase 2) number of correctly advised surveillance intervals 3) number of correctly predicted diminutive (1-5mm) lesions 4) number of surveillance intervals predicted on endoscopic diagnosis 5) number of correctly diagnosed small (6-9mm) lesions 6) budget impact analysis | — |
