Background and study aims
Barrett’s oesophagus is a condition where the lining of the gullet (food pipe/oesophagus) changes in response to inflammation usually caused by heartburn (acid reflux). This is a common condition but, in some people the lining of the gullet can change further to become cancerous. To identify cases at a treatable stage, the British Society of Gastroenterology guideline advised patients with Barrett’s oesophagus should have regular endoscopies (camera test down the gullet) every 2-5 years. This is known as surveillance. Currently, in the NHS, these tests are performed during a trained doctor or nurse endoscopy session. Within these sessions the endoscopist may see many different conditions and conduct different types of procedure.
This study aims to see if it would be beneficial or not to have a dedicated Barrett’s endoscopy session conducted by a doctor or nurse with a specialist interest in that area. There has been no previous research to ascertain whether a dedicated list improves the quality of the endoscopy performed. To assess this, Barrett’s oesophagus patients will be asked if they would be happy to be chosen at random to have their surveillance procedure during any endoscopy session (current normal practice) or on a dedicated Barrett’s endoscopy session. Participants will be asked to complete a questionnaire about how they feel about their condition, the care they receive and their symptoms. Information will also be collected about the camera test and biopsy results to check how closely the care provided follows current best practice guidelines.
It is hoped that this pilot study will provide the basis to justify a larger study to look for differences between the two types of service.
Who can participate?
Any adult (aged over 18 years) patient who has a diagnosis of Barrett's oesophagus who comes for regular routine camera tests to monitor it and is able to understand the study and make decisions for themselves.
What does the study involve?
Eligible, interested participants will be invited to meet a member of the research team to discuss the study and answer any questions about the study. If the participant is happy to be part of the study the researcher will explain the study and ask them to sign a consent form. Participants will then be chosen at random to have the surveillance procedure during any endoscopy session (current normal practice) or on a dedicated Barrett’s endoscopy session. Participants will not be told which list they have been allocated to. This will help keep the study results accurate and fair, but the procedure will be similar to previous experiences of surveillance for participants.
Presently there is no evidence that either service is better for patients, however if participants have any concerns this can be discussed with the study team before consent to participate is given.
After the endoscopy test, participants will be provided with a questionnaire to complete at home about their condition, and the care that they have received. The study team will also collect information about the camera test and biopsy results. After the test and completion of the questionnaire participants will return to current normal care and study involvement is complete. The consent process for the study should only take around 10 to 20 minutes, the endoscopy will last a long as usual surveillance tests experienced by the participant, and the questionnaire takes about 30-60minutes to complete.
What are the possible benefits and risks of participating?
The study may not have a direct benefit to the participants but will help to understand of Barrett’s oesophagus care pathways and support a larger study that may show one of these interventions improves the outcomes for Barrett’s patients. Although no health risks are expected to be associated with this study, there is some possibility that slightly different techniques will be provided at the different endoscopy lists. However, all participants will be seen by a clinician qualified to perform the test. There is no proof yet that either list is better than the other.

| Scientific title | A randomised controlled pilot trial comparing current Barrett’s oesophagus surveillance endoscopy practice with a dedicated service |
| Study acronym | DEBO pilot |
| Study objectives | A randomised controlled trial comparing a dedicated endoscopy service for Barrett's oesophagus versus current normal practice is feasible in the UK NHS hospital setting |
| Ethics approval(s) | Approved 29/06/2020, MREC Greater Manchester South (3rd Floor, Barlow House, 4 Minshull Street, HRA NRES Centre Manchester M1 3DZ; +44 (0)207 104 8010; gmsouth.rec@hra.nhs.uk) |
| Health condition(s) or problem(s) studied | Barrett's oesophagus |
| Intervention | The dedicated service will be performed by an upper GI specialist consultant, nurse endoscopist, or clinical research fellow who has a specialist interest in the condition. This is defined by a self-declared interest and regular experience of performing Barrett's surveillance. The list should be scheduled appropriately and include only Barrett's patients. The non-dedicated lists are any other list performed by an endoscopist who is accredited by the Joint Advisory group to perform upper GI endoscopy who does not have a specialist interest in Barrett's and does not attend upper GI multidisciplinary meetings. Patients who are known to have Barrett's oesophagus and who are due for their scheduled surveillance endoscopy will be found via booking department databases by the research nurses, chief investigator, principle investigator, or research fellow. They will be approached via sending an invitation letter with a participant information sheet in the 6-8 weeks approaching their endoscopy. They will invited to meet one of the study team who will check their capacity and consent them for the study. Once they have consented to be in the study they will be randomised by the clinical trials assistant with an envelope-assisted randomisation procedure to either the dedicated list or routine list. The participant will not be informed which list they have been allocated. Once randomised the participant will be allocated an endoscopy appointment by the endoscopy booking team with the endoscopists in both arms of the study blinded to the participants involvement in the study. Both study sites have an established dedicated service, hence it will be possible to blind the endoscopists in both arms. In hospitals with a dedicated service it is not uncommon for Barrett's surveillance to be allocated onto different endoscopy lists due to timing and availability therefore this closely reflects normal practice. Once the endoscopy has been completed the research team will access the report and the biopsy results to find the data for the clinical outcome measures. The research team will input retrieved data onto an anonymised clinical reference form which is marked only with the participant's unique study number. The participant will be made aware that the study team will access this information during the written consent. Each participant will have one endoscopy only and this will be the endoscopy which is already planned in their surveillance programme. The participants will be provided with a questionnaire after their endoscopy to complete at home with which they will be given a stamped addressed envelope for ease of return. They will be advised to complete it at home away from the endoscopy unit and to avoid confounding proximity to their endoscopy. The study will just look at the differences between the questionnaire outcomes, the endoscopy report documentation, and the biopsy results. The participant's ongoing follow-up and further surveillance will continue as normal after the study. Added 10/01/2023: Alongside the DEBO pilot a subsidy exploring clinician behaviours will run. This will involve interviewing clinicians about their experience of performing Barrett's surveillance using prompts based around the Theoretical Domains Framework of behaviour and interpreted using the COM-B model of behaviour change. This element of the study will involve interviews undertaken on Microsoft teams with telephone consent, and purposeful sampling used to recruit clinicians from a wide geographical and clinical background. Transcripts will be analysed using thematic analysis with a view to determine areas which could be focused on in terms of interventions to affect behaviour in future intervention trials. Recruitment will continue until thematic saturation is achieved this will likely be in the order of 10-20 participants. |
