HardMental health and behavioural emergenciesSelf-harm with alcohol intoxicationMRCEM SBA

A 29-year-old woman attends the emergency department after deliberately cutting her forearm following an argument. She has attended twice for self-harm in the past month. The wound requires suturing but has no tendon, nerve or vascular injury. She is physiologically stable. Her blood alcohol concentration is 110 mg/100 mL, but she is alert, converses coherently and can describe what happened. She denies current suicidal intent and agrees to remain for assessment. A triage risk scale categorises her as ‘low risk’. Liaison psychiatry is available. Which assessment and disposition plan is most appropriate?

Correct answer: B — Arrange liaison psychosocial assessment alongside wound care, then plan disposition and aftercare from its findings.

She needs treatment of the wound and a psychosocial assessment, but these should proceed concurrently rather than sequentially. She can currently engage in conversation, so the measured alcohol concentration is not a reason to postpone assessment. Her denial of suicidal intent and ‘low-risk’ score do not establish that discharge is appropriate: NICE advises against using risk scales to determine discharge. Liaison assessment should inform a collaborative plan for her safety, disposition and aftercare. ([nice.org.uk](https://www.nice.org.uk/guidance/ng225/chapter/recommendations)) A is attractive because wound closure is necessary, but completing it before requesting assessment introduces an avoidable delay. C would become reasonable if intoxication prevented meaningful engagement and observation or admission were needed; an alcohol concentration alone does not establish that. D mistakes a screening category for a discharge decision and defers the specialist assessment that should be offered at this attendance. E recognises the importance of repeated self-harm, but recurrence alone does not establish a need for psychiatric admission before assessment. Admission may be appropriate if the subsequent assessment identifies a need for inpatient care. ([nice.org.uk](https://www.nice.org.uk/guidance/ng225/chapter/recommendations))
