Involuntary psychiatric admission based on risk rather than need for treatment: report from the Dublin Involuntary Admission Study (DIAS).

Aims Involuntary psychiatric admission in Ireland is based on the presence of mental disorder plus serious risk to self/others and/or need for treatment. This study aimed to examine differences between use of risk and treatment criteria, about which very little is known. Methods We studied 2,940 admissions, of which 423 (14.4%) were involuntary, at three adult psychiatry units covering a population of 552,019 people in Dublin, Ireland. Results Involuntary patients were more likely than voluntary patients to be male, unmarried and have schizophrenia or a related disorder. Involuntary admission based on the ‘risk criterion’ (rather than the ‘treatment criterion’ or both) was associated with a shorter period as an involuntary patient for patients with diagnoses other than schizophrenia. Conclusion If inpatient units are intended as treatment centres rather than risk management units, the balance between considerations of risk and treatment requires careful re-examination in the setting of involuntary psychiatric care.
