In terms of information on accident and emergency (A and E) departments, national health service trusts self-report the number of A and E services they provide against definitions set by the Department for the three types of A and E. This information is not available at the level of individual hospitals.
Population data are also available at the level of strategic health authorities.
Reports for example by Collins (1999) “Organisation of acute general services” Joint Consultants Committee, and from the Royal College of Surgeons (2006) “Delivering high quality surgical services for the future—a consultation document from the Royal College of Surgeons of England reconfiguration working party”, make reference to suggested catchment areas for hospitals and services that should be available.
