Family request for nondisclosure in a patient with delirium and brain metastases
An 81-year-old man with newly diagnosed metastatic pancreatic cancer and a recent cerebral metastasis is admitted with confusion. He speaks Cantonese and understands little English. His son, who is bilingual, says the family does not want his father told the diagnosis because it would 'destroy his hope.' The patient is alert but disoriented to place and time; he can state his name and that he wants 'no machines.' His oncologist is due to discuss palliative chemotherapy. The son offers to interpret and asks you to sign a form stating the patient lacks capacity. There is no advance directive.
1. How would you assess decision-making capacity, and what role should the son's interpretation play?

Capacity is decision-specific, not a global label. I would assess whether he can understand the relevant information about diagnosis and palliative chemotherapy, appreciate how it applies to him, reason with the options, and express a consistent choice. Delirium from brain metastasis, steroids, infection, dehydration or opioids may be reversible; I would screen, treat causes, and reassess. I would use a professional Cantonese interpreter, not the son, for the assessment. The son can provide cultural context and support, but he should not be the sole interpreter for consent or capacity. I would not sign a pre-printed form before assessment. If he can express 'no machines' and understand simple choices, he may retain capacity for some decisions even if disoriented to place and time.
2. How should you respond to the family's request for nondisclosure if the patient has capacity?

If he has capacity, the family's request cannot override his right to receive information. I would meet him with a trained interpreter, ask how much he wants to know and whom he wants present, and explore the family's fears without promising silence. I would explain that I can share information gently and in stages, but I cannot lie if he asks directly. I would ask him whether he wants his son to hear details first or to help with decisions. If he says he prefers not to know, that is his choice, not the family's. I would document the conversation and the family's concerns. This approach respects cultural values while maintaining honesty and trust.
3. If the patient lacks capacity, what process should guide treatment decisions and documentation?
Read the worked answer
If he lacks capacity for the treatment decision, I would follow the local legal framework for substitute decision-making, usually the family or a legally appointed representative, and use the best-interests standard. I would consider his previously expressed wish of 'no machines,' his values, the benefits and burdens of palliative chemotherapy, and the views of the family and treating team. I would hold a family meeting with a trained interpreter, involve palliative care and, if there is conflict, the ethics committee. I would not use the son's request for nondisclosure as a reason to withhold information from the decision-maker, but I would explore what the patient would have wanted. I would document the capacity assessment, the decision process, the participants and the rationale.
