Summary

Better patient education prior to colonoscopy improves adherence to instructions for bowel preparation and leads to cleaner colons. The hypothesis of this trial is that computer assisted instruction (CAI) using video and 3D animations can maximize the effectiveness of nurse counselling and consequently improves bowel cleanliness. Furthermore, CAI will positively influence the patient experience.

Adults referred for colonoscopy were included in a Dutch large volume endoscopy unit. Exclusion criteria were illiteracy in Dutch and audiovisual handicaps. Patients were prospectively divided into two groups, one receiving nurse counselling and one receiving CAI and a nurse contact before colonoscopy. The main outcome, cleanliness of the colon during examination, was measured with the Ottawa Bowel Preparation Scale (OBPS) and the Boston Bowel Preparation Scale (BBPS). Patient comfort and anxiety were assessed at multiple time points: directly after the instruction and one hour before colonoscopy. Comfort was rescored 2 hours after colonoscopy. We also tested knowledge and comprehension one hour before colonoscopy. Statistical analyses included Mann-Whitney.

Computer Assisted Instruction

The computer assisted instruction consisted of a platform using video mimicking the patient journey with voice-over supported by photo's, 3D animation and instructive texts. The video was presented in short clips, maximal 45 seconds, to maintain the focus of patient. Patient interaction was ascertained by mandatory mouse-click after each item in the CAI. All elements of informed consent for colonoscopy (risks, alternatives) were included.
