Station brief
Format. Communication station, approximately 7–10 minutes after reading time. You are the psychiatry registrar. The patient is being stabilised medically; you meet the sister. [2]
Candidate instructions. Explain what neuroleptic malignant syndrome is, link it to dopamine-blocking medicines without minimising seriousness, describe what the team is doing now (stopping those medicines, cooling, fluids, monitoring), and answer questions about whether medication can ever be restarted. Avoid jargon dumps and avoid inventing legal section numbers. [1][3]
Candidate scenario
Sister: “You gave him too many antipsychotics and now he’s burning up. Are you covering up a mistake? Will he die? He can’t be psychotic forever without medicine — what happens next?” Observations confirm fever and rigidity; transfer to HDU is arranged. [2]
Marking domains
- Empathy, clear structure, no defensiveness
- Accurate plain-language explanation of NMS as rare serious reaction to dopamine-blocking drugs
- Explicit statement that those medicines are stopped and medical care is prioritised
- Honest prognosis: serious but usually recoverable with early treatment
- Balanced rechallenge message: often possible later after full recovery, different medicine, slow, monitored — not immediate restart
- Collaborative plan and check understanding [1][2][3]
Reveal assessor key
Open. Introduce role, acknowledge fear and anger, sit, minimise interruptions. “I can see how frightening this looks — you are right to ask direct questions.” [2]
Explain NMS. “We think he has a rare but serious reaction called neuroleptic malignant syndrome. Medicines that block dopamine — used for psychosis — can rarely cause high fever, muscle stiffness, blood-pressure swings, and confusion. It is a medical emergency. We are not ignoring a link to medication.” [1]
What we are doing. “We have stopped those medicines. The priority is hospital medical care: cooling, fluids, close monitoring of heart, breathing, kidneys, and muscle breakdown blood tests. Extra antipsychotic for agitation would be unsafe. If needed, specialist medicines or, rarely, ECT are considered for severe cases.” [2]
Prognosis and rechallenge. “This is serious, and people can become very unwell, but with early recognition most recover. When he is fully better, if antipsychotic treatment is still essential, we usually wait a period after recovery and then consider a different medicine at a low dose, increased slowly with monitoring. Many people can take an antipsychotic again safely, but we never rush it.” [3]
Close. Summarise, invite questions, offer written information and named contact, document discussion. [2]
