Purpose of report This document has been commissioned by the British Society of Gastroenterology. It is intended to draw together the evidence needed to fill the void created by the absence of a national framework or guidance for service provision for the management of patients with gastrointestinal and hepatic disorders. It sets out the service, economic and personal burden of such disorders in the UK, describes current service provision, and draws conclusions about the effectiveness of current models, based on available evidence. It does not seek to replicate existing guidance, which has been produced for upper and lower gastrointestinal cancers, hepatobiliary and pancreatic disorders, and many chronic disorders of the gut. It does, however, draw on evidence contained in these documents. It is intended to be of value to patient groups, clinicians, managers, civil servants, and politicians, particularly those responsible for developing or delivering services for patients with gastrointestinal disorders.

Methods used A systematic review of the literature was undertaken to document the burden of disease and to identify new methods of service delivery in gastroenterology. This systematic review was supplemented by additional papers, identified when the literature on incidence, mortality, morbidity, and costs was assessed. Routine data sources were interrogated to obtain additional data on burden of disease, the activity of the NHS, and costs, in relation to gastrointestinal disorders.
