The accident and emergency department management of deliberate self-poisoning.

Consecutive attenders (525) presenting at the Nottingham Accident and Emergency (A & E) department with deliberate self-poisoning were identified retrospectively. Their case-notes were examined for patient characteristics and clinical management. The Nottingham Psychiatric Case Register was examined for previous contact and use of psychiatric services over a 2-year follow-up period. Significant differences were found between those patients admitted to a ward and those who returned home from the A & E Department, in respect of likelihood of psychiatric morbidity and use of psychiatric services. One in three self-poisoning patients returns home directly from the accident department, and there seemed to be appropriate selection.
