Liaison psychiatry in general practice: the comprehensive collaborative model.

A model of liaison psychiatry in general practice is described and its impact assessed using data from the Nottingham psychiatric case register. The model incorporates a comprehensive network of general practice psychiatric clinics for both psychiatrists and other mental health professionals, associated with mainly informal liaison with general practitioners and others in the primary care team, and a reduction in psychiatric outpatient clinics. Following the introduction of this model, the proportion of new and referred patients seen in primary care settings rose from 1% to 18% in Nottingham over an 8-year period. Over this period admission rates significantly fell in Nottingham compared with the rest of England and evidence is given that the growth of primary care psychiatry contributed significantly to this reduction.
