An observational study in Training and Endoscopy, sponsored by Gloucestershire Hospitals NHS Foundation Trust. Recruiting at 1 site in United Kingdom. Per ClinicalTrials.gov, last updated 2026-01-29.
Sponsored by Gloucestershire Hospitals NHS Foundation Trust · Observational
Endoscopy services are under significant pressure and endoscopy training academies and immersion training are under review at a national level. To date, there has been no comprehensive evaluation of the different approaches to immersion training or a large-scale study looking at its impact on trainees and/or endoscopy services. The purpose of this study is to perform a process, impact and economic evaluation of current immersion training practices to determine if they are impactful and value for money.
Retrospective quantitative analysis involves endoscopists (training between January 2022 and the study start date) who may (or may not) have undertaken immersion training. Prospectively analysis will be performed to evaluate the impact of immersion training.
Gloucestershire Hospitals NHS Foundation Trust is the lead sponsor of 21 studies on the registry; 3 are open to participants now.

Endoscopy trainees
Inclusion Criteria:
Endoscopy trainees (Surgical, Gastroenterology or CE) who have received (or are soon to undertake) immersion training in either gastroscopy or colonoscopy
Rate of improvement in DOPS (Direct Observation of Procedural Skills) score during immersion training compared to base hospital training
Rate of change in DOPS supervision assessment overall score - % of ratings competent for independent practice. Case matched interrupted time series analysis immersion trainees versus non-immersion trainees.
Time frame: 6 months from start of data collection
Caecal intubation rate (CIR)/ duodenal (D2) intubation rate improvement during immersion training compared to base hospital training?
% of procedures where trainee endoscopist advances the whole length of the colon to the caecum / successful intubation of the second part of the duodenum (D2) without assistance. Case matched interrupted time series analysis immersion trainees versus non-immersion trainees.
Time frame: 6 months from start of data collection
Improvement in time, and number of procedures, required for certification during immersion training compared to base hospital training?
Number of days between starting training and achieving certification (allowing for breaks in training e.g. parental leave) and number of procedures performed between starting training and achieving full certification. Case matched interrupted time series analysis immersion trainees versus non-immersion trainees.
Time frame: 6 months from start of data collection
Increase in number of endoscopies performed independently post certification following immersion training compared to base hospital training?
Number of endoscopies performed independently 3 months / 6 months/ 12 months post-certification. Case matched interrupted time series analysis immersion trainees versus non-immersion trainees.
Time frame: 6 months from start of data collection
Improvement in confidence scores following immersion training.
Do trainees feel more confident following immersion training? Survey and/or in-depth interviews with immersion trainees.
Time frame: 6 months from start of data collection
