Endoscopy Immersion Study.

January 22, 2026 updated by: Gloucestershire Hospitals NHS Foundation Trust

Understanding the Impact of Endoscopy Immersion Training in Regional Endoscopy Academies: is it Value for Money?

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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Rate of improvement in DOPS (Direct Observation of Procedural Skills) score during immersion training compared to base hospital training
Time Frame: 6 months from start of data collection
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.
6 months from start of data collection
Caecal intubation rate (CIR)/ duodenal (D2) intubation rate improvement during immersion training compared to base hospital training?
Time Frame: 6 months from start of data collection
% 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.
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?
Time Frame: 6 months from start of data collection
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.
6 months from start of data collection
Increase in number of endoscopies performed independently post certification following immersion training compared to base hospital training?
Time Frame: 6 months from start of data collection
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.
6 months from start of data collection
Improvement in confidence scores following immersion training.
Time Frame: 6 months from start of data collection
Do trainees feel more confident following immersion training? Survey and/or in-depth interviews with immersion trainees.
6 months from start of data collection
