A set of patient information leaflets is provided on CD-Rom. These can be printed out and given to patients. A set of summary cards is provided: they are designed to be used interactively by the clinician in order to facilitate discussion with the patient during the consultation.Suggested template charts of information about local resources for people suffering mental and neurological ill health are also provided. The text of the book is available in searchable HTML format on the Centre for Evidence Based Mental Health website: www.mentalneurologicalprimarycare.org The evidence base for the recommendations on treatments is set out: but the guidance contains much more than the outcomes of trials of the efficacy of particular treatments. It represents also the clinical wisdom of a very large group of experts whose collective experience of mental and neurological health in primary care is enormous. Although designed primary with primary care clinicians in mind, the book will be useful to others who work with primary care in the fields of mental health and neurological health - including community health workers, voluntary organizations and primary care patients. The guidance in this book is compatible with ICD-10 and with the Clinical Terms (Read Codes), which are used by GPs.As such, it provides a common language to help all those working in mental and neurological healthcare - primary and secondary care clinicians, patients, families and community groups - to communicate with each other. The volume is a highly practical, simple to use tool that can help make neurological and mental health care a more integral part of primary healthcare practice.
