''Lyttles Mental Health and Disorder'' is the leading textbook in this field, for students and practitioners alike. This completely revised third edition addresses the changes that have taken place in education, as well as in the organisation and provision of care and includes coverage of the new standards being disseminated by the National Service Frameworks for Mental Health. The aim of this book is to provide guidance that will support practitioners in delivering systems of care that are responsive to the needs of the patient or client. As a result aspects of delivery such as accurate and strong clinical leadership, risk assessment, medication management programmes and rational care planning processes, that feature in most policy statements, are to be found in this edition.
