Chest Pain in a Patient Who Wants to Stay Home
You attend a 58-year-old woman with a 90-minute history of central chest pressure radiating to the left arm, associated with nausea and sweating. She is pale and clammy; BP 148/92, pulse 96 regular, SpO2 95% on room air, respiratory rate 20. ECG shows ST elevation in leads II, III and aVF. She is alert and oriented and repeatedly states she does not want to go to hospital because she is her husband's sole carer and 'cannot leave him'. Her husband, who has moderate dementia, is present and agitated. She has capacity to make and communicate decisions. You have aspirin, glyceryl trinitrate, analgesia and oxygen available.
1. Analyse how you would balance respect for her refusal against your duty of care, and set out the steps you would take.

The starting point is that an adult with capacity is entitled to refuse treatment and transport, even where that refusal may lead to serious harm or death. Capacity is decision-specific and must be assessed, not assumed from the fact that you disagree with the choice.
Steps:
- Confirm capacity formally. Can she understand the information, retain it, weigh it, and communicate her decision? Her stated reason (caring responsibilities) shows she understands the situation and is weighing consequences - that is consistent with capacity, not evidence against it.
- Give clear, honest information about the likely diagnosis and the time-critical nature of treatment, in plain language, without coercion or scare tactics. Explain what happens if she declines.
- Explore the barrier rather than arguing. Her objection is practical, not a rejection of care. Ask what would need to be true for her to go. Options include contacting a family member, neighbour, or social services, or arranging for her husband to be supported while she is assessed.
- Involve others appropriately with her consent - a relative, GP, or out-of-hours service - to help solve the caring problem.
- If she still refuses after informed discussion, document the capacity assessment, the information given, the options offered, and her decision. Offer to re-attend, provide safety-netting advice, and ensure her husband's welfare is addressed.
- Do not physically compel or deceive her. Transporting a capacitous refusing patient against her will would be an assault and a serious professional breach.
The tested judgement is distinguishing a genuine capacitous refusal from an unmet need, and addressing the need without overriding autonomy.
2. Would your approach differ if, on assessment, she was confused and unable to repeat back the risks you described? Explain.
Read the worked answer
Yes, materially. If she cannot understand, retain, or weigh the information - for example, she cannot repeat back in any form what you have told her, or her confusion is new - then she may lack capacity for this decision at this time. In that situation:
- The refusal no longer carries the same weight, because it is not an informed decision.
- You should act in her best interests, which in a time-critical ST-elevation presentation means treating and transporting.
- You should consider reversible causes of the confusion (hypoxia, hypoglycaemia, hypotension, drugs) and treat them, then reassess capacity.
- You should involve next of kin and document the capacity assessment and the best-interests reasoning.
- You should still address the husband's welfare, but his care cannot justify withholding emergency treatment from a patient who lacks capacity.
The key point is that capacity is a moving assessment; the same words ('I don't want to go') mean very different things depending on the patient's cognitive state.
3. Set out the pharmacological actions you would take and justify each.
Read the worked answer
- Aspirin (chewed, per local protocol dose): antiplatelet effect in suspected acute coronary syndrome; benefit is time-dependent, so give early unless contraindicated (allergy, active bleeding).
- Glyceryl tritrate for ongoing pain, with caution: check BP first (148/92 is acceptable), avoid if hypotensive or if right ventricular involvement is suspected, and reassess after each dose.
- Analgesia for pain control - pain drives sympathetic activation and myocardial oxygen demand.
- Oxygen only if hypoxaemic. At 95% on room air she does not meet a typical threshold for supplemental oxygen; routine high-flow oxygen in normoxaemic ACS is not supported and may be harmful.
- Antiemetic if nausea and vomiting threaten absorption of oral agents.
Each intervention should be tied to a documented indication and a reassessment. The tested judgement is avoiding reflexive 'everything at once' treatment and matching each drug to a specific, current indication.
