At the time of the project the Department had a list of Regional Public Health Directors but did not have a detailed contact list of all Public Health Directors working in over 302 primary care trusts across England. However, 155 of the 279 invitations were sent directly to Directors of Public Health. Further to the reconfiguration in 2006 a more streamlined approach is now taken when seeking information from national health service organisations. The Chief Executive Bulletin is used to filter down information, and requests for information, to appropriate personnel in the NHS.
