Station brief
Format. Communication station, approximately 7–10 minutes after reading time. You are the psychiatry registrar on the medical ward. The patient is receiving antibiotics for pneumonia and is being nursed with close observation. [1]
Candidate instructions. Explain delirium in plain language, link it to the pneumonia and hospital factors, describe the care plan (treat infection, review medicines, reorientation, avoid unnecessary sedatives), answer questions about "madness" and dementia, and carefully address financial capacity — do not facilitate opportunistic property transfer while she is delirious. [1][2][3]
Candidate scenario
Son: “She was fine last month. Now she is either climbing out of bed or half asleep. Psychiatry needs to knock her out at night. Is this dementia? Can she still sign the house papers I brought?” Observations show fluctuating alertness and inattention; pneumonia is being treated. [1]
Marking domains
- Empathy and structure without defensiveness
- Accurate plain-language explanation of delirium as an acute medical brain syndrome
- Clear plan: treat causes + multicomponent non-drug care; antipsychotics only if severe distress/danger
- Avoid routine benzodiazepine "sleepers" for non-withdrawal delirium
- Honest prognosis: often improves as medical illness improves, but recovery can lag; increased risk of complications
- Capacity: decision-specific; major financial acts inappropriate while delirious; involve appropriate legal/substitute pathways
- Check understanding and offer written information/contact [1][2][3]
Reveal assessor key
Open. Introduce role, acknowledge fear and frustration, sit at eye level. “You are right that this change is sudden and frightening — that pattern is important.” [1]
Explain delirium. “We think she has delirium — an acute confusional state. The brain’s attention systems are temporarily disrupted by the pneumonia, medicines, sleep disruption, and hospital environment. It is a medical problem, not that she has suddenly developed schizophrenia. It can happen on top of mild memory problems.” [1][3]
Plan. “We treat the infection and review medicines that worsen confusion. We use reorientation, glasses/hearing aids, family presence, day-night routines, and early mobilisation. Strong sleeping tablets often make delirium worse. If she becomes dangerous to herself despite these steps, we may use a short course of a low-dose medicine for safety — not to ‘cure’ the confusion.” [2][3]
Dementia and prognosis. “This presentation is delirium. Some people with delirium already have underlying cognitive impairment, and delirium can increase later dementia risk, so we will reassess cognition after she recovers. Many people improve as the medical illness settles, though it can take time.” [1]
Finances. “Signing major property documents while delirious is not appropriate. Capacity is about understanding and weighing a specific decision at a specific time. While she is fluctuating, she should not execute major financial transfers. We can involve the medical team, social work, and the proper legal substitute decision-making process if needed.” [1][3]
Close. Summarise, invite questions, provide named contact, document discussion. [1]
