Authorship in any project involving multiple contributors can be a difficult issue. Whenever we publish any project from the group it will be under the guise of a project team, with several levels of involvement which will be made clear from the outset. 

The project will involve a central steering group, writing committee and data management team, and project co-ordinators and data collectors for each unit. It is anticipated that key personnel will be part of several of these sections and would be counted as part of the standard authorship, as would leaders of each section. 

All contributors would gain a citable reference which can be verified by PubMed as in the example shown by the London Surgical Research Group website here.
