Primary care-psychiatry interaction: a British perspective.

Three models of interaction between primary care and psychiatry in the British National Health Service are presented. Although the first two are traditional and well recognized, the third, the liaison-attachment model, is an innovation of the last decade. Two studies are described that outline the extent and nature of this form of working collaboration between specialists and generalists. Clinical, service, and educational implications are discussed in the context of the British primary care structure.
