Refusal of Investigation and Informed Consent
A 48-year-old woman has four months of progressive dysphagia to solids and liquids with 8 kg weight loss and mild anaemia. Upper gastrointestinal endoscopy is recommended, but she refuses because a relative died shortly after a colonoscopy. She is fully alert and competent. Which is the most appropriate next action by the physician?
- A.Discharge her from the clinic today
- B.Arrange a family meeting without her
- C.Explore her specific fears and misconceptionsCorrect
- D.Ask her son to sign the consent form
Explanation
A competent adult has an absolute right to refuse investigation, but refusal is often driven by a specific and correctable fear rather than a settled value judgement. The first professional obligation is therefore to explore the reason behind the refusal, in this case a frightening experience with a relative after a different procedure. Exploring her concern allows the physician to correct misconceptions about risk, explain sedation and monitoring, describe the actual complication rates, and clarify what the alternatives and consequences of not investigating would be. This respects autonomy while ensuring the decision is genuinely informed, which is the core requirement of valid consent or valid refusal. Her presentation of progressive dysphagia to both solids and liquids with weight loss and anaemia carries a high probability of oesophageal malignancy, so the stakes are high and a rushed acceptance of refusal is negligent. Asking a relative to consent is invalid because no adult can consent on behalf of a competent adult. Discharging her abandons the patient and breaches the duty of care. Convening the family without her permission breaches confidentiality. If she still refuses after full discussion, document the conversation and offer alternatives such as barium swallow and continued follow-up.
Why each option
- A.
- Discharging a patient with red flag dysphagia abandons her and breaches the duty of continuing care.
- B.
- Discussing her case with family without her consent breaches confidentiality and does not address her own concerns.
- C.
- Correct. Understanding and addressing the specific fear is the first step and allows an informed rather than a fear driven decision.
- D.
- A competent adult cannot have consent given by a relative; substitute decision making applies only when capacity is lacking.
