All ethical dilemmas stationsPLAB 2 Ethical Dilemmas

Capacity and refusal of treatment station

Mental capacitychallenging

This station tests the principle that a person with capacity may refuse even life-saving treatment. The examiner wants a proper capacity assessment and respect for autonomy, not persuasion at any cost.

How to structure it

  • Explore the reasons behind the refusal without judgement.
  • Provide clear information about the risks and the alternatives.
  • Assess capacity formally — understand, retain, weigh and communicate.
  • If they have capacity, respect the decision and document it; if not, act in their best interests.
  • Safety-net and arrange appropriate follow-up.

Common pitfalls

  • Conflating an unwise decision with a lack of capacity.
  • Pressuring or coercing the patient.
  • Failing to document the assessment and decision.

Examiners reward a structured capacity assessment, respect for autonomy, and clear, non-coercive communication.
