As modern healthcare evolves, it is essential for nurses to understand and work with a diverse range of people to provide quality care. But, it is often difficult to grasp the many roles of those in healthcare services. This book provides a clear, practical, and up-to-date guide to the various people that nurses work with, including the essential role of service users themselves and how to work with them to improve care. This second edition includes increased coverage of teamwork and mental health. It is updated throughout, and includes discussion of the UK's LiNKS (Local Involvement Networks), the Care Quality Commission, and Every Child Matters.
