Forces such as political conflict, globalisation and the growth of the internet, offering news of life elsewhere, mean levels of migration are higher now than at any other time in history. Despite the signing of a number of legally binding international treaties that seek to guarantee health care for migrants, there is still a considerable gap between government commitments and the reality of everyday life. As levels of migration continue to increase, it is essential for health care professionals to consider the differing needs of migrants in order to provide them with quality care. Informed by systemic theory, and drawing on the author's extensive clinical – as well as personal – experience, this timely book explores the limited existing information about migrants' health care experiences. Providing a comprehensive insight into a worldwide issue, this is an essential guide for health care students, professionals and policy makers.
