Outcomes
Primary outcome [1] 0 0
Bowel preparation quality
Timepoint [1] 0 0
Bowel preparation quality is scored once for each patient at the time of colonoscopy completion. We expect to conduct this score in 500 patients over the study period of approximately 12 months.
Secondary outcome [1] 0 0
Colonoscopy cancellation rate
Timepoint [1] 0 0
Colonoscopy cancellation rate will be calculated at the time of study completion, expected to be 12 months.
Secondary outcome [2] 0 0
Caecal intubation rate
Timepoint [2] 0 0
Caecal intubation rate will be calculated at the time of study completion, expected to be 12 months.
Secondary outcome [3] 0 0
Polyp detection rate
Timepoint [3] 0 0
Polyp detection rate will be calculated at the time of study completion, expected to be 12 months.
