Book excerpt: As health policy at a national level has ever increasing impact on local health services, it is essential that public health students understand how the development and implementation of policy and strategy provide the framework for improving quality, innovation, productivity and prevention in the delivery of healthcare. The book is divided into two sections, with section one covering a strategic overview of national policies, and section two giving specific local implementation of policy examples to support section one. Case studies and examples will help the reader to understand the policy and strategy and to apply them to their local setting.
