Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Preparation efficacy is evaluated by the blinded colonoscopist. Bowel preparation is assessed by the validated Ottawa Bowel Preparation Scale, the Aronchick scale and the Boston Bowel Preparation Scale based on the preparation scores from three segments of the colon (right colon, transverse colon and left colon), as well as a score for overall colonic fluid. Quality measures of colonoscopy are reported such as caecal intubation, intubation and withdrawal times, polyp detection rate and complications. | — |
Secondary
| Measure | Time frame |
|---|---|
| Adverse events will be recorded for 30 days after colonoscopy. Blood will be collected after the preparation and right before the procedure to assess electrolyte shifts and will be tested for bicarbonate, blood urea nitrogen, calcium, chloride, creatinine, magnesium, phosphate, potassium, sodium, haemoglobin and hematocrite. A questionnaire is used to assess tolerance of the bowel preparation. This questionnaire will assess complaints such as bloating, cramping, nausea and overall burden such as impedement of activities, interrupted sleep at night and problems in transport to the hospital. All items are scored on a 5-point Likert scale | — |
