Brief Summary

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.

Conditions

Training; Endoscopy

Outcome Measures

Primary Outcomes (5)

• 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.

  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.

  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.

  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.

  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.

  6 months from start of data collection
