There are few evaluations of strategies to improve rates of early detection and treatment of patients with first-episode psychosis.


To evaluate the effectiveness of a general practitioner (GP) education programme and an early detection assessment team (the Lambeth Early Onset Crisis Assessment Team; LEO CAT) in reducing delays in accessing treatment for first-episode psychosis patients.


46 clusters of GP practices randomised to GP education in early detection with direct access to LEO CAT v. care as usual. Primary outcome measures were GP referral rates, duration of untreated psychosis (DUP) and delays in receiving treatment.


150 patients with first-episode psychosis were recruited; 113 were registered with the study GPs, who referred 54 (47.7%) directly to mental health services. Significantly more intervention group GPs (86.1% v. 65.7%) referred their patients directly to mental health services and fewer patients experienced long delays in receiving treatment. However, their overall DUP was unaffected.


Educating GPs improves detection and referral rates of first-episode psychosis patients. An early detection team reduces the long delays in initial assessment and treatment. However, these only impact on the later phases of the DUP. Broader measures, such as public health education, are needed to reduce the earlier delays in DUP.
