Recently in the United Kingdom some new organisational structures for clinicians have been discussed. So far little has changed, but the intensity of interest suggests this may be an opportunity to link change in working practices with improvements in quality. Multidisciplinary team working is developing within the National Health Service (NHS) and some groups are expanding their roles across traditional institutional boundaries to form complex clinical networks. It would require little to make these functional networks autonomous from current NHS structures. Other models of working without traditional institutional boundaries have been discussed, including the formation of "chambers" for doctors and other professionals. We describe the first tentative steps of one group as an example and suggest that further experimentation with evaluation is required.
