Background/Objectives: The past decade has seen a rise in specialist mental health teams delivering specific functions, such as crisis resolution and home treatment teams, assertive outreach teams and early intervention services for psychosis. Such services have been introduced in a range of countries in the developing world, but are nowhere more prominent than in England, where they have been a mandatory component of services for the past decade. We now have some evidence that service models such as early intervention and crisis resolution are effective under the right conditions. Regarding their implementation, a key current debate is whether functions such as early psychosis and crisis resolution need to be delivered by distinct specialist teams, or whether they can be wholly or partly integrated into generic community teams. We will describe a mixed methods investigation of this issue, focusing on implementation of early intervention for psychosis within a catchment area mental health system. Methods: Eleven geographically defined mental health sectors within an inner city catchment area have been allocated at random to receive either (a) a specialist multidisciplinary team providing early intervention for psychosis for all young people aged between 18 and 35 experiencing a first onset of psychosis in the area and (b) an ‘augmented’ community mental health team model, with specialist early intervention workers embedded within community mental health teams. We examined (a) differences in case detection between areas with these two models, (b) differences in patient outcomes, and (c) experiences of implementing the two models. Interviews with patients using structured quantitative outcome measures were used to examine the former and qualitative methods the latter. Results: Case detection rates were significantly lower in areas with the augmented community mental health team worker model than in those served by the specialist team. This appears to reflect a number of difficulties in implementing the early intervention model within community mental health teams. They included pressures against prioritising early onset psychosis cases without very florid pathology, tensions within teams regarding implementation of the augmented team model, lack of a team approach, and differing attitudes to presentations close to the threshold for psychosis. Alongside quantitative and qualitative data describing these issues, we will present data on outcomes for 200 patients whose sectors have been randomised to either the specialist team or augmented community mental health team model. Discussion/Conclusions: The implementation difficulties encountered in introducing a specialist focus on early intervention to a generic community mental health team were considerable, casting doubt on current arguments that generic teams may be in a position to deliver specialist functional services economically.
