A New Approach to Mental Health Crisis
When someone in Limerick experiences a severe mental health crisis, the traditional response has been to call an ambulance, attend an emergency department, and, in many cases, face involuntary admission to a psychiatric unit under the Mental Health Act. It is a process that is often traumatic for the person in crisis, costly for the health system, and — as mental health advocates have long argued — frequently unnecessary if the right community-based support is available.
Limerick's Community Acute Support Team (CAST) was established a year ago to test a different approach. The team — comprising psychiatric nurses, social workers, occupational therapists, and peer support workers — provides intensive, round-the-clock community-based support to people experiencing acute mental health crises, with the aim of preventing hospital admission and, in particular, involuntary detention.
The results of its first full year of operation, published this week by the HSE Mid-West, are striking: CAST prevented 133 involuntary psychiatric detentions, supported 847 people through acute crises in their own homes or in community settings, and achieved a 94% rate of successful crisis resolution without hospital admission.
How CAST Works
The CAST model is based on the principle that most mental health crises, even severe ones, can be managed safely in the community if the right support is available quickly enough. When a referral comes in — from a GP, a family member, a community mental health team, or directly from the person in crisis — a CAST team is deployed within two hours. The team conducts a comprehensive assessment and develops an immediate support plan, which might include daily home visits, medication management, crisis counselling, and practical support with housing, finances, or family relationships.
"The key is speed and intensity," says CAST clinical lead Dr Sinéad Ní Mhurchú. "If we can get to someone quickly, before the crisis escalates to the point where hospital admission becomes unavoidable, we can usually find a way to support them safely in the community. That's better for the person, better for their family, and better for the health system."
The team operates seven days a week, with an on-call service available overnight for urgent situations. It works closely with the Limerick and Ennis general hospitals, the HSE's community mental health teams, and a range of voluntary sector organisations including Pieta House and the Samaritans.
The Human Impact
Behind the statistics are individual stories of people whose lives have been changed by CAST's intervention. One service user, who asked to be identified only as Máire, described how CAST supported her through a severe depressive episode last autumn that would previously have resulted in hospital admission. "They came to my house every day for three weeks," she said. "They helped me with my medication, they talked to my family, they helped me get through the worst of it without having to go into hospital. I don't know what would have happened without them."
For Máire, the alternative — involuntary admission to a psychiatric unit — would have meant losing her job, disrupting her children's lives, and the stigma that still, despite progress, attaches to psychiatric hospitalisation. "CAST gave me the chance to get better on my own terms," she said. "That matters enormously."
A Model for the Nation?
Mental health advocates and HSE officials are now calling for the CAST model to be rolled out nationally. A Sharing the Vision, Ireland's national mental health policy, explicitly calls for the development of community-based acute support services as an alternative to hospital admission, but implementation has been slow and patchy.
Mental Health Reform CEO Fiona Coyle said the Limerick results were "exactly what we have been calling for" and urged the Minister for Mental Health to commit to a national rollout. "The evidence is clear: community-based acute support works, it saves money, and it produces better outcomes for people. There is no excuse for not implementing it everywhere."
The HSE has confirmed that it is reviewing the CAST model with a view to establishing similar teams in Cork, Dublin, and Galway in 2027, subject to funding. For the 133 people in Limerick who avoided involuntary detention this year, that cannot come soon enough.
