Previous evidence has shown that standards of performance in gastrointestinal endoscopy are variable and that there are disparities in training outcomes. Many changes have been made recently to both training and assessment of endoscopy in the UK. However, no prospective methods of evaluating their outcome have been put in place. The aims of this research were to evaluate current and new training processes and assessments in order to quality assure the outcomes and improve the training process. Two audits were undertaken demonstrating improvements in colonoscopy training over 5 years within a single region and in trainee perceptions of their training nationally. Two studies were done investigating a novel computer colonoscopy simulator for assessment of colonoscopic skills, demonstrating excellent construct validity. A multi-centre randomised controlled trial evaluated the use of this simulator in novice training, which was shown to be equivalent to standard bed-side training with a high degree of skills transfer to real-life colonoscopy. Assessment tools for therapeutic endoscopic procedures were developed, validated and used to quality assure a course in therapeutic endoscopy. This course resulted in significant improvements in practical skills for three of the four therapeutic procedures following training. Web-based training and assessment modules for lesion recognition at capsule endoscopy were developed, validated and piloted. This demonstrated the effectiveness of using new training methodologies for skills improvement in this area. A training course for radiographers in virtual colonoscopy was developed and the training evaluated. This demonstrated competence in practical performance and improvements in knowledge and interpretative skill. Finally, two qualitative studies on non-technical skills in endoscopy were undertaken in order to widen the assessment domains from purely knowledge and skill. An interview study provided the basis for development of a nontechnical skills taxonomy and a video-analysis study resulted in production of a marker system for professional behaviour within gastrointestinal endoscopy.
