The 34-year-old with first-episode psychosis and a language barrier
A 34-year-old man, a recent migrant from a rural area, is brought to the emergency department by his brother. He has not slept for five nights, is convinced the neighbours have installed cameras in his flat, and has stopped eating because he believes the food is poisoned. He speaks limited English; his brother interprets. On examination he is guarded, with poor eye contact, but there is no overt aggression. He denies any intention to harm himself or others. Vital signs and basic bloods, including glucose and inflammatory markers, are normal. He has no known psychiatric history and no access to psychiatric services. The department is busy, and a bed is unlikely for at least 12 hours. His brother asks whether he can just take him home and 'keep an eye on him'.
1. What are the key elements of your initial risk and diagnostic assessment, and how do you handle the interpreting issue?

The assessment must cover immediate safety, a structured attempt at diagnosis, and an explicit plan for the language problem. First, suicide and violence risk: persecutory delusions with food refusal and sleep deprivation raise risk, but the absence of command hallucinations, hopelessness or expressed intent lowers acute risk; document the reasoning, not just the conclusion. Second, a collateral history from the brother is essential - duration of symptoms, premorbid function, substance use, head injury, fever, and any prior episodes. Third, screen for organic causes: normal glucose and inflammatory markers are reassuring but do not exclude delirium, so check orientation, attention and fluctuation; consider urine toxicology and, given the migrant background, a low threshold for infection and nutritional screening. Fourth, the language issue: relying on a family member as interpreter is acceptable for rapport and practical matters but risky for sensitive content, because relatives may soften or omit suicidal ideation, and the patient may censor himself. Use a professional interpreter for the mental state examination and for discussions of detention and treatment. Record which interpreter was used. Do not let the busy department justify a shortcut: the decision about admission hinges on the quality of this assessment.
2. The brother wants to take him home. How do you decide, and what legal and ethical framework applies?
Read the worked answer
The decision rests on capacity, risk and the least restrictive option. Assess whether he can understand, retain, weigh and communicate decisions about staying in hospital versus going home. His delusional beliefs about poisoned food and cameras suggest impaired ability to weigh information, so capacity is doubtful. Risk factors favouring admission: food refusal with possible dehydration, no insight, no established community follow-up, a home environment he believes is under surveillance, and a brother who cannot supervise continuously. Against admission: no aggression, no suicidal intent, and the harms of coercive detention. If he lacks capacity and risk is significant, detention under the relevant mental health legislation is justified, with the least restrictive option chosen - a voluntary informal admission if he agrees, otherwise formal detention. The brother's offer to supervise is relevant but not sufficient without a clear plan, a crisis number, and a review within 24 hours. Document the discussion with the brother, his concerns, and why his proposal was or was not accepted. Inform the patient in a way he can understand, using the interpreter, and explain his rights of appeal.
