Throughout the health care system, the traditional boundaries between professional groups are becoming increasingly blurred in response to local service needs and national policy objectives. New clinical roles are developing and nurses and other health professionals are finding opportunities to review and reconfigure their roles in response to changing health care needs and national policy imperatives. This book grew out of the editors involvement in the UKCCs work on the regulation of specialist, advanced and higher level practice and Department of Health research on new role developments and the impact of the `New Dealreduction in junior doctors hours. It combines a comprehensive and thought provoking overview of the key issues and emerging challenges with practical suggestions for promoting appropriate and sustainable role development.
