Psychiatry: practice, law & professional skills
Emergency psychiatry
Emergency psychiatry covers the urgent assessment and treatment of people in acute mental health crises, such as severe agitation, suicidal behaviour, acute psychosis or intoxication. It is where psychiatrists must think fast, keep everyone safe and rule out physical causes.

What is it?
Psychiatric emergencies arrive at any hour: a young man brought by police after violent behaviour, a woman who has taken an overdose, an older person suddenly confused and frightened, a student in a panic attack convinced they are dying. The emergency psychiatrist must quickly work out what is going on, whether anyone is in danger, and what to do next.
A key principle is that physical illness can look like mental illness. Low blood sugar, infections, head injury, drug intoxication or withdrawal, and thyroid problems can all cause confusion, agitation or hallucinations. So emergency psychiatry always works closely with emergency medicine.
In Malaysia, junior doctors and psychiatry medical officers handle most out-of-hours psychiatric calls, with specialists available on call. Decisions often involve the Mental Health Act, police and families.
Why does a psychiatrist need it?
Crises are when patients are at greatest risk and when good decisions save lives. Psychiatrists must de-escalate safely, use rapid tranquillisation only when needed, assess suicide and violence risk, use legal powers correctly, and decide between admission, home treatment or follow-up.

Common questions
What counts as a psychiatric emergency?
Any situation where someone's mental state puts them or others at immediate risk, such as suicidal behaviour, severe agitation, acute psychosis, or confusion that may have a medical cause. These need urgent assessment, usually in an emergency department.
Why do psychiatrists check blood tests in an emergency?
Because physical problems such as infection, low blood sugar, drug effects or head injury can look like mental illness. Ruling these out is part of safe emergency psychiatry.
