Consent: Shared Decision-Making, Risk, Refusal and Valid Authority
Consent in procedures and complex clinical contexts
A procedure may generate more paperwork, but the underlying standard is unchanged: the patient needs an opportunity to understand the proposed intervention, the material risks and benefits, reasonable alternatives and what may happen without it. The depth of the discussion should reflect complexity, uncertainty and the patient's priorities. The clinician...
Learning objectives
• Apply core consent principles to procedural care, including timing, role clarity and change of plan. • Recognise linked but distinct decisions such as procedure, anaesthesia and transfusion. • Apply current professional guidance to intimate examinations, teaching involvement and patient recordings. • Recognise when a material change in procedure, risk or circumstance requires renewed discussion.
Procedural consent is still a dialogue
A procedure may generate more paperwork, but the underlying standard is unchanged: the patient needs an opportunity to understand the proposed intervention, the material risks and benefits, reasonable alternatives and what may happen without it. The depth of the discussion should reflect complexity, uncertainty and the patient's priorities.
The clinician who seeks consent must be able to explain the intervention sufficiently for the patient to decide. Local governance may allow trained practitioners to undertake parts of the process, but a signature from someone who cannot answer relevant questions is not a safe endpoint.
One episode of care can contain several decisions
Surgery, anaesthesia, blood transfusion, imaging contrast, invasive monitoring and postoperative plans can each raise distinct choices. Consent to the overall operation does not automatically demonstrate informed agreement to every linked intervention. Teams should make responsibility visible: who discussed which component, what was decided and what still needs review.
Timing matters
RCoA perioperative guidance emphasises early information and shared decision-making. Significant foreseeable decisions should not be deliberately postponed until immediately before a procedure when the patient is anxious, in pain or affected by premedication. The day-of-procedure team should still confirm that the patient continues to understand and agree with the plan.
Blood transfusion has current UK guidance
The 2025 SaBTO guidance states that informed and valid consent should be obtained for patients who may, are likely to or will definitely receive a transfusion, including where transfusion might later be needed while the patient is incapacitated. It emphasises active shared decision-making, alternatives, the right to refuse or withdraw consent, and clear documentation.
A patient may accept some blood components and refuse others. That distinction should be documented in the clinical and transfusion records so that it is visible to teams who later administer treatment.
Intimate examinations need explicit attention
GMC guidance requires explanation, consent or other valid authority, respect for privacy and dignity, and the offer of a chaperone wherever possible. The patient should know that they can ask for the examination to stop at any time. Consent for a clinical examination does not automatically authorise a separate teaching examination.
A change of plan can invalidate assumptions
If new imaging, intraoperative findings or clinical deterioration materially changes the proposed procedure or its risks, the team should ask whether the earlier consent still covers the new decision. If the patient can participate, revisit the discussion. If they cannot and an unplanned decision is urgent, use the applicable legal framework and keep intervention within lawful necessity.
Applied scenarios
Scenario 1
A patient has signed a surgical consent form but has not discussed a material anaesthetic option that particularly concerns them.
Scenario 2
New imaging changes the proposed operation substantially, but the team plans to reuse the old form without further discussion.
Scenario 3
An intimate examination is proposed for teaching after the clinical examination and the team assumes the original clinical consent covers it.
Practice checklist
- Identify all linked decisions in the episode of care rather than relying on one form.
- Ensure the person seeking consent has sufficient knowledge and knows when to involve the responsible clinician.
- Discuss significant foreseeable procedures early enough for questions and reflection.
- Use current SaBTO guidance and local policy where transfusion may be required.
- For intimate examinations, explain, obtain consent, offer a chaperone and respect requests to stop.
- Revisit consent when a material change in plan, risk or purpose occurs.
