Summary
Brief summary (as posted)
In a cluster-randomized study compare if feedback from two computerized feedback systems doing a colonoscopy (CoPS and CoRS) can improve the adenoma detection rate and decrease patient discomfort.

- description
- Performing the standard procedure in accordance with the departments usual conduct.
Primary outcomes (2)
- measure
- Feedback from CoRS results in change in Adenoma Detection Rate for individual operators and for the department as a whole.
- timeFrame
- Baseline (pre-intervention) and with the end of each time cluster (month 8, 12, 16, 18). The intervention will be at different time clusters for the three participating hospitals, and therefore the baseline sampling period will be different.
