Up to fifty patients who should be released, some with learning disabilities and autism, are stuck in secure units run by mental health hospital charities. St Andrew's Healthcare treats up to 900 patients with severe mental health and learning difficulties. 90% of referrals are from the NHS and need specialist care. However there is a lack of suitable community places, so seclusion is the emergency response. Seclusion rooms are bare, with a hatch in the door for patients to receive food and have physical contact. BBC TV footage showed a teenager locked in seclusion, able to touch their parent only through a door hatch. Patients are supposed to be admitted to these units for nine to 18 months, but the average stay nationally is five years. One patient was detained an extra 524 days after they should have been released.
