Background and study aims
Endoscopy (colonoscopy) is the gold standard investigation for abnormalities of the gastrointestinal tract, allowing for direct visualisation, taking tissue samples and, where required, therapeutic intervention. It is well recognised that the quality of bowel preparation affects the outcome of colonoscopy. Inadequate bowel preparation can lead to diseases being missed or for the procedure needing to be repeated. Up to 20% of colonoscopies have inadequate bowel preparation. Repeat procedures can be stressful for patients and delay diagnosis. It is therefore vital to optimise bowel preparation for colonoscopy. To improve the safety and quality of bowel preparation, some units employ a team specialised in pre-colonoscopy assessment but this is a costly option. According to the office of national statistics, 86% of households in Great Britain had internet access in 2015. A reliable internet-based educational video may be an effective method to educate patients about bowel preparation leading improved adequacy. This study will assess whether an educational video explaining how to take bowel preparation leads to a more effectively cleared bowel.
Who can participate?
Adults who speak English and require a colonoscopy to assess for bowel disease, and have access to the internet or a DVD player
What does the study involve?
The study will assess whether an educational video regarding bowel preparation for colonoscopy improves its effectiveness. Half the participants will receive access to the video, whilst the other half will not. Who receives access will be determined by chance. The effectiveness of the bowel preparation for the colonoscopy will then be recorded and compared between the two groups.
What are the possible benefits and risks of participating?
A more effectively cleared bowel allows a more thorough examination of the colon. Therefore, if the video is successful in improving bowel preparation then participants who have access to it are less likely to have abnormalities missed. They are also less likely to require a repeat procedure due to poor preparation. The possible risks involved are the standard risks of a colonoscopy examination; however, watching the video will not increase these risks.
Where is the study run from?
Nottingham University Hospital and 5 other hospitals in the UK

| Ethics approval(s) | Nottingham Research Ethics Committee 1, 11/12/2018, ref: 18/NW/0768 |
| Health condition(s) or problem(s) studied | Colonoscopy bowel preparation |
| Intervention | Patients will be randomised to viewing an educational video which explains what a colonoscopy is and how to take bowel preparation, alongside standard written instructions or to standard written instructions alone. Participants will be randomised using simple randomisation to two groups, the control group and the intervention group. The control group will receive the standard written instructions provided prior to colonoscopy explaining how to take the bowel preparation solution. The intervention group will receive the standard written information and will also receive access to an educational video with the same content but presented in a different media format. Participants will be asked to review this information prior to taking the bowel preparation solution. They will complete questionnaires prior to and subsequent to the endoscopy to collect data on patient demographics, anxiety, satisfaction and comfort. Once they have completed the questionnaires after the endoscopy their involvement in the study will be completed. |
