Assessment and treatment service (ATS) does the initial assessment and may continue to be involved for a time or refer on to other specialist resources. The team may be subdivided. One part may focus on more complex situations that require several professionals to be involved
and have care programme approach (CPA) plans to ensure this care is coordinated. Other teams work with less complex situations where people need less input.
Assertive outreach teams (AOT) work to engage and maintain relationships with ‘high risk’ people who are suffering with psychosis and are chaotic and not willing, or able, to keep regular appointments or cooperate with medication programmes. This team may step in after others have been unable to maintain a treatment plan.
Early intervention service (EIS) works with other teams to offer specialist help to younger people (under 35 years old) experiencing their first psychotic episode. This early treatment has been shown to greatly improve the long term outcome.
Crisis resolution home treatment team (CRHT) offers frequent intensive contact to try to prevent an admission to hospital or to speed up being discharged home safely. They can visit or call several times a day and will assess anyone who might be admitted to hospital to see if they can offer an alternative through support at home.
There are also specialist services for children (known as CAMHS – Child and adolescent mental health service) and for older adults with organic conditions such as dementia or with other MH needs there are specialist older adults MH services.
