Objective: The process of detecting people at high risk of schizophrenia from a community sample is a major challenge for prevention of psychotic disorders. The aim of this paper is to describe early detection procedures that can be implemented in primary care settings.
Methods: A selected literature review is supplemented by experiences and data obtained during the Buckingham Integrated Mental Health Care Project.
Results: General medical practitioners have been favoured as the agents most likely to prove helpful in detecting the key risk factors that predict the onset of schizophrenic disorders, as well as in recognising the earliest signs and symptoms of these conditions. However, the practical problems of screening for multiple and subtle risk factors in general practice are substantial, and general practitioners (GPs) often have difficulty recognising the earliest signs of a psychotic episode. A range of strategies to assist GPs detect early signs of psychosis in their patients are considered.
Conclusions: It is feasible to implement primary care setting early detection procedures for people at risk of schizophrenia. Implementation is aided by the use of a brief screening questionnaire, training sessions and case supervision; and increased collaboration with mental health services and other community agencies.
