Research summary
Research Summary:
Endoscopy is the gold standard investigation for pathology of the gastrointestinal tract, allowing for direct visualisation, tissue acquisition 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 to be repeated. 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.
90% of households in Great Britain had internet access. Using a reliable internet-based educational video for patients to watch may be an effective method to educate patients about bowel preparation leading to improved adequacy.
Patients usually receive written information to explain how the preparation should be taken. In this study there will be two groups; a control group and an intervention group. The control group will receive written instructions. The intervention group will receive written instructions as well as access to an educational video. This video explains the importance of bowel preparation and the most effective way to complete it. Patients in the intervention arm will receive access to the video at the time of their appointment in the form of an internet link or DVD. They will be instructed to watch the video prior to taking their bowel preparation. Patients will undergo bowel preparation at home before attending the endoscopy unit on the day of their procedure. The effect on the adequacy of bowel preparation will be measured as well as patients satisfaction, anxiety as well as other indicators of an adequate colonoscopy examination.Lay summary of study results:
Colonoscopy is the best test of the large bowel. The bowel must be cleared with the use of a laxative drink. Good bowel clearance is vital to colonoscopy. Unfortunately, poor cleansing is common. One in five tests have poor cleansing.
A patient who knows what to do is best. They are more likely to follow the instructions. They’re also more likely to complete the cleansing laxative drink. We think that an educational video could lead to better patient understanding. They would then be better able to complete the bowel preparation regime.
We created an educational video. The Nottingham Trent graphics department helped to create this. The video was reviewed by a patient group. They advised on its content. It was designed to educate patients to undertake the bowel cleansing process. To best assess how good the video was, we conducted a clinical trial. This was the EBOPs study. Half the patients received the video. The other half received the standard written instructions on bowel preparation. 509 patients attending for their first colonoscopy were recruited to take part in the study. 6 different NHS trusts across the East Midlands and Sheffield took part. The study was a success. Fewer patients had poor bowel cleansing in the group who received the educational video. This meant a better quality of test. We plan to share these findings with the endoscopy community. This may allow the improvement in colonoscopy practice.REC name
