Early intervention in psychosis

Early intervention in psychosis is a clinical approach to those experiencing symptoms of psychosis for the first time. It forms part of a new prevention paradigm for psychiatry and is leading to reform of mental health services, especially in the United Kingdom and Australia.

This approach centers on the early detection and treatment of early symptoms of psychosis during the formative years of the psychotic condition. The first three to five years are believed by some to be a critical period. The aim is to reduce the usual delays to treatment for those in their first episode of psychosis. The provision of optimal treatments in these early years is thought to prevent relapses and reduce the long-term impact of the condition. It is considered a secondary prevention strategy.

The duration of untreated psychosis (DUP) has been shown as an indicator of prognosis, with a longer DUP associated with more long term disability.

There are a number of functional components of the early psychosis model, and they can be structured as different sub-teams within early psychosis services. The emerging pattern of sub-teams are currently:

Multidisciplinary clinical teams providing an intensive case management approach for the first three to five years. The approach is similar to assertive community treatment, but with an increased focus on the engagement and treatment of this previously untreated population and the provision of evidence based, optimal interventions for clients in their first episode of psychosis. For example, the use of low-dose antipsychotic medication is promoted ("start low, go slow"), with a need for monitoring of side effects and an intensive and deliberate period of psycho-education for patients and families that are new to the mental health system. Interventions to prevent a further episodes of psychosis (a "relapse") and strategies that encourage a return to normal vocation and social activity are a priority. There is a concept of phase specific treatment for acute, early recovery and late recovery periods in the first episode of psychosis.

Interventions aimed at improving the detection and engagement of those early in the course of their psychotic conditions. Key tasks include being aware of early signs of psychosis and improving pathways into treatment. Teams provide information and education to the general public and assist GPs with recognition and response to those with suspected signs, for example: EPPIC's Youth Access Team (YAT) (Melbourne); OPUS (Denmark); TIPS (Norway); REDIRECT (Birmingham); LEO CAT (London).
