Implementation of Point Of Care UltraSound in the Assessment of Crohn's Disease -The POCUS Study

Overview

1. Explore Stakeholder perceptions of POCUS service development and implementation in the NHS in an interview Sub-study. We will assess whether stakeholders: * Recognise the potential of POCUS for the management of small bowel CD; * feel that it should be integrated into local services; * feel that they have the skills/resources to deliver POCUS; * can establish criteria for the service success of POCUS. 2. Compare the impact of POCUS and MRE on the nature of decision-making of consultant gastroenterologists and their confidence in clinical decision making. 3. Undertake care pathway analyses of POCUS and MRE service for IBD outpatients with small bowel CD.
