Factors associated with the non-assessment of self-harm patients attending an Accident and Emergency Department: results of a national study.

BACKGROUND: Psychosocial assessment of self-harm patients by mental health service staff is an important aspect of their care. Nevertheless, in England around half of those attending a general hospital following a self-harm episode do not receive such an assessment. We have investigated the reasons for this and the characteristics of patients associated with self-discharge or planned discharge without a psychosocial assessment. METHOD: 8-week audits of self-harm attendances were carried out in 32 Accident and Emergency Departments in England. Where a specialist psychosocial assessment by mental health services was not carried out, information on the reason for this was requested. Due to incomplete data 10 of the 32 hospitals were excluded from analysis. RESULTS: There were 2780 self-harm attendances at the 22 hospitals. Psychosocial assessments were carried out on 59% of episodes. Among those not assessed, 57% discharged themselves and the remainder were discharged by hospital staff. In multivariable models, being male, taking illegal drugs/alcohol, attendance out of office hours and not being admitted to a hospital bed were associated with an increased risk of self-discharge. Younger subjects were more likely to self-discharge, but this association was explained by age-related admission patterns. Young age (
