Abstract:
The aim of this study was to develop and validate structured evaluation tools to measure performance in upper gastrointestinal endoscopy using a multidisciplinary approach. This study was built on a United Kingdom multi-centre randomised controlled trial, (the Multi-Institution Nurse endoscopy Trial, MINuET). I studied three important components of performance in upper gastrointestinal endoscopy: Endoscopic skills, patient satisfaction with endoscopy and the quality of endoscopy reporting. Endoscopic skill was assessed by analysis of video recordings using a scale that was validated in the course of this study (the Swansea OGD scale). Patient satisfaction was measured using a new scale, the gastrointestinal endoscopy satisfaction questionnaire (GESQ), which was also validated. I developed the Swansea OGD scale using quality criteria from textbooks, professional body recommendations and the literature. 188 videos were assessed. It has a good factor structure on factor analysis, internal consistency, good inter-rater and intra-rater reliability. It has face validity, content validity and construct validity. The GESQ was developed and validated from responses from 1563 patients. It has a good factor structure, internal reliability, face validity, content validity and is interpretable. The quality of endoscopy reporting was variable and sub optimal, which I tested on the 552-endoscopy reports by doctors or nurses. Endoscopic skills correlated with patient satisfaction with procedure. I have shown the Swansea OGD scale to be valid and reliable. The GESQ is a valid instrument to measure patient satisfaction with endoscopy. The quality of endoscopy reporting was variable and sub optimal. This multidisciplinary approach can be used to assess quality of performance in upper gastrointestinal endoscopy in a structured and reliable fashion.
