Prompt
After a severe acute behavioural disturbance is controlled in ED, the patient's sister asks why police said it was 'excited delirium', whether that means he is 'crazy and dying from adrenaline', and what you did with medication and restraint.

Station brief

Format. Communication and clinical reasoning station, approximately 7–10 minutes after reading time. You are the psychiatry registrar in ED after the acute episode has been controlled. [2]

Candidate instructions. Explain what happened using acute behavioural disturbance language; address the sister's concern about the term excited delirium without being dismissive; describe medical priorities (temperature, monitoring, why medication was used, goal of calm not unconsciousness); explain restraint minimisation and safety; outline investigations and next steps; discuss capacity and legal principles without inventing statute section numbers. [1][3]

Candidate scenario

The patient is now rousable with oxygen saturations normal. Sister says: “They told us it was excited delirium — is that a real disease? Did the police nearly kill him? Why inject him?” [1]

Marking domains

  • Empathic, plain-language engagement without jargon overload
  • Prefers ABD / severe behavioural disturbance framing; explains ExDS is contested and not used as a sole diagnosis
  • Clear medical priorities: safety, temperature, monitoring, treat cause
  • Honest explanation of medication purpose and monitoring (calm and able to talk)
  • Acknowledges restraint risk and that position/duration matter
  • Capacity and least-restrictive principles without invented legal codes
  • Collaborative plan and follow-up [1][2][3]
Reveal assessor key

Open. Introduce role, check understanding of what she has been told, acknowledge fear and anger after a frightening scene. [2]

Terminology. Explain we describe this as acute behavioural disturbance — a dangerous state of extreme agitation that can have medical causes such as stimulants, heat, infection, or mental illness. The phrase excited delirium is contested, not a standard psychiatric diagnosis in DSM or ICD, and major toxicology bodies advise against using it as a diagnosis or sole cause of death. We focus on what we measure and treat. [1][2]

What we did. Safety first; checked breathing, oxygen, sugar, temperature; cooled him; used medication (for example droperidol-class or protocol agent — name if true to case) so he could be assessed safely; goal is calm and rousable, not knocked out; we monitor breathing and vitals frequently for at least an hour after injections. [3]

Restraint. Physical holds are last resort and kept as short as possible; prolonged face-down restraint is dangerous for breathing; we document what happened and reassess continuously. Do not accuse individuals without facts, but do not deny that restraint can contribute to harm. [1]

Next steps. Blood tests, heart tracing, observation for toxin effects or mental illness; if capacity impaired and serious risks remain, local mental health law may allow treatment using the least restrictive safe option — you will involve seniors and will not invent section codes. Invite questions; summarise plan. [3]
