The National Association of Psychiatric Intensive Care Units and low secure units (NAPICU) is a multi-disciplinary clinician led not-for-profit organisation committed to the development of psychiatric intensive-care units and low secure services in the UK. It was formed following the 1st National Conference on Psychiatric Intensive Care held in London in 1996 and organised by Dr Dominic Beer, Dr Stephen Pereira and Pharmacist Carol Paton. The association holds quarterly meetings, academic seminars and an annual national conference.
