i think Crisis team is Slightly different, we have crisis team too, and they provide a similar service to the one you describe.
EIP is focused more on engagement and intervention of people with first episode psychosis before they are diagnosed. i was thinking they would be a good source for you to gain data and information for your research.
Teams in the NHS will be easy to locate through the NHS websites and there will be people in the organisation that you could contact, i am sure. i could help point you in the right direction if you would like?

http://pb.rcpsych.org/cgi/content/full/25/4/146Early intervention in psychosis is a strategy for which there is increasing theoretical and
pragmatic justification. Many studies have been published describing the benefits of early intervention as carried out by specialised and innovative projects. The present paper describes how a generic community mental health team (CMHT), covering a population of 50 000, introduced strategies for early intervention with no extra funding. The team worked together to change old attitudes and practices. A style of intervention was developed to engage with and keep in contact with people with recent onset psychosis. This appears to be achievable — and this model may be an alternative to the setting up of specialised teams.
The early intervention movement
International interest in this area has grown rapidly in the past 10 years, with progress being presented in a supplement to the British Journal of Psychiatry (1998, 172, Suppl. 33). Much of the rationale for early intervention comes from changing views of schizophrenia. The old Kraepelinian idea of gradual and inevitable decline has been challenged. It has been observed that on many measures the illness reaches its peak of severity after 2-5 years, after which the level of disability remains the same or may decrease — the ‘plateau effect’ (McGlashen, 1988). Long-term outcome studies (Mason et al, 1996; Warner, 1994) have confirmed the heterogeneity of outcome in schizophrenia.
Many people who develop psychotic illness go untreated for long periods — 1-2 years on average. This untreated period may set in train processes — biological, psychological and social — that add greatly to the subsequent chronicity of the illness. Psychosis may be ‘toxic’ to the brain. Also, social and psychological damage done may be irreversible. The ‘critical period’ hypothesis (Birchwood et al, 1998) suggests that given these new insights into the illness there may be a window of opportunity for intervening early.
Early intervention is used to describe two different things. In this paper it refers to a strategy for treating early psychotic illness as quickly and effectively as possible. It involves shortening the duration of untreated psychosis and tackling the problems of non-engagement with services. It is thus a secondary prevention strategy. A second, more ambitious, early intervention strategy involves trying to intervene with people before the psychosis develops. This is an exciting prospect but is not beyond the research stage — and is not discussed here.
