Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main study parameter is the ADR, calculated as the number of patients in whom at least one adenoma is detected during the colonoscopy procedure, divided by the total number of patients that underwent the colonoscopy procedure. | — |
Secondary
| Measure | Time frame |
|---|---|
| - AADR, calculated as the number of patients in whom at least one advanced adenoma is detected during the colonoscopy procedure, divided by the total number of patients that underwent the colonoscopy procedure - PDR, calculated as the number of patients in whom at least one polyp is detected during the colonoscopy procedure, divided by the total number of patients that underwent the colonoscopy procedure - TSDR, calculated as the number of patients in whom at least one SSL is detected during the colonoscopy procedure, divided by the total number of patients that underwent the colonoscopy procedure - Indication specific ADR, i.e., ADR specific for screening, diagnostic, or surveillance - Mean number of adenomas detected per patient - Mean number of polyps detected per patient - Number of sessile serrated lesions - Number of advanced adenomas (adenomas >= 10 mm and/or with a villous component and/or with HGD - Size of the lesion subdivided in categories 0-5 mm, 6-10 mm, 10-20 mm, >20 mm - Location of the lesion: cecum, ascending colon, transverse colon, descending colon, sigmoid, rectum; - Morphological characteristics of the lesion using the Paris classification (Ip, Is, IIa, IIb, IIc, III) - Histopathological characteristics of the lesion according to the Vienna classification - ADR of the first 20% of patients that have undergone colonoscopy by each endoscopist will be compared with the final 20% of patients in each arm to identify any changes in ADR throughout the trial - Bowel cleansing using the BBPS - Cecal intubation rate (CIR) - Procedure times with both techniques (i.e., total procedure time, mean polypectomy time and withdrawal time) - (Severe) adverse events (S)AEs up to 30 days post-procedure - SAEs will be subcategorized into colonoscopy related, cardiac (cardiac ischemia, heart failure, arrhythmia, other) pulmonary (exacerbation COPD, infectious, other), neurological (stroke, cerebrovascular accident, bleeding, other), | — |
