Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Boston Bowel Preparation Scale (continuous) | Perioperative/Periprocedural | Quality of bowel preparation measured by the Boston Bowel Preparation Scale. Scores range from 0 through 3. Higher scores indicate a better outcome.. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Polyp detection rate proportion | Perioperative/Periprocedural | Proportion of individuals undergoing a colonoscopy in whom at least one polyp is detected. Values range from 0 through 1. Higher values indicate a better outcome. |
| Adenoma detection rate proportion | Perioperative/Periprocedural | Proportion of individuals undergoing a colonoscopy in whom at least one adenomatous polyp is found. Values range from 0 through 1. Higher values indicate a better outcome. |
| Cecal intubation rate proportion | Perioperative/Periprocedural | Proportion of colonoscopies in which the endoscope successfully reaches the caecum. Values range from 0 through 1. Higher values indicate a better outcome. |
| Withdrawal time | Perioperative/Periprocedural | Duration in minutes taken to withdraw the colonoscope from the caecum to the rectum. Values range from 1 through 60. Higher values indicate a worse outcome. |
| Boston Bowel Preparation Scale (categorical) | Perioperative/Periprocedural | Boston Bowel Preparation Scale adequacy of preparation score ≥ 2 in all regions. Quality measured by the Boston Bowel Preparation Scale. Scores range from 0 through 3. Higher scores indicate a better outcome.. |
| Amsterdam Preoperative Anxiety and Information Scale | baseline | Self-assessed at baseline using the Amsterdam Preoperative Anxiety and Information Scale (APAIS). Scores range from 6 through 30. Higher scores greater anxiety. |
| Overall experience with the bowel preparation process | Perioperative/Periprocedural | Self-report about experience with the bowel preparation process. One original question with 5 choices of very unpleasant, unpleasant , neutral , pleasant , very pleasant . There is no score. The best answer would be very pleasant. |
| Desire to undergo future colonoscopies if indicated | Perioperative/Periprocedural | Self-report about having another colonoscopy. One original question with 5 choices of strongly disagree, disagree, neutral, agree , strongly agree. The best answer would be strongly agree. |
| Adherence to bowel preparation instructions | Perioperative/Periprocedural | Following what was told to do by bowel preparation instructions. Total of 7 original questions scored as no for 0 or yes for 1 with a total score ranging from 0 through 7. Higher values indicate a better outcome. |
