In an ageing world, the delivery of psychogeriatric services in an effective and efficient manner is an increasing concern for health service providers and administrators in both developed and developing countries. Despite awareness of the anticipated mental health needs of the ageing population, services for older people have been slow to develop in many places, and in some places do not exist at all.This volume brings together the theory and practice of psychogeriatric service delivery from an international perspective. It examines the range of different service models, perspectives and ideas with the evidence-base for each, providing a unique resource for those planning and administering psychogeriatric services.The first section of the book discusses the theory behind psychogeriatric service delivery, including its history, service delivery principles, needs analysis, population-based service planning, economics and funding, and evidence-based service delivery. Section two concentrates on practice, describing examples of service delivery from a number of European, American, African, Asian and Australasian settings. The third section focuses on solutions, evaluating the range of delivery settings and considering the needs of both consumers and carers.
