Consent and patient counselling

Surgical approach (if applicable)

Not an operation. Consent and counselling are shared clinical processes across perioperative care.
- Surgeon usually consents for the surgical procedure (indication, alternatives, material risks, expected benefits, postoperative course).
- Anaesthetist consents for the anaesthetic plan (GA/regional/sedation), anaesthetic risks/benefits/alternatives, and perioperative pain strategy.
- Shared areas: blood transfusion, critical care admission, DNACPR/ceilings of care, perioperative complications with overlapping causation (e.g., nerve injury, awareness, aspiration).

Anaesthetic management (if applicable)

Not procedure-specific. Consent is required for any anaesthetic intervention (including cannulation, arterial lines, neuraxial blocks, sedation, GA).
- Type of anaesthesia: depends on surgery/patient; consent should cover reasonable alternatives (GA vs regional vs local/sedation).
- Airway: ETT/SGA/awake technique as relevant; discuss material risks (e.g., sore throat, dental injury, failed intubation, aspiration).
- Duration: procedure-specific; include perioperative pathway (theatre, recovery, possible HDU/ICU).
- Pain: procedure-specific; discuss analgesic options (opioids, regional, PCA, neuraxial, multimodal) and key risks (PONV, pruritus, respiratory depression, LAST, nerve injury).

Core principles (what makes consent valid)

Consent must be: voluntary, informed, and given by a patient with capacity (or via lawful best-interests process if lacking capacity).
It is a process, not a signature: ongoing dialogue, opportunity for questions, and can be withdrawn at any time.
The person performing the intervention (or with appropriate knowledge and delegated authority) should take consent; anaesthetists should consent for anaesthesia-related interventions.
Document: what was discussed, patient’s questions/concerns, decisions made, and any specific risks that were emphasised.

Legal framework (UK): capacity, information disclosure, and standards

Capacity (Mental Capacity Act 2005, England/Wales): presume capacity unless established otherwise; decision-specific and time-specific.
- Test: can the patient understand, retain, use/weigh relevant information, and communicate the decision (any means).
- Support decision-making: interpreters, hearing aids, written info, time, treat pain/anxiety, involve family if patient agrees.
Information disclosure standard (Montgomery v Lanarkshire 2015): must disclose material risks and reasonable alternatives.
- Material risk: a reasonable person in the patient’s position would likely attach significance to it, or the clinician should reasonably know this patient would.
- Move away from purely clinician-centred ‘reasonable body of medical opinion’ disclosure (Bolam-style) for consent.
Negligence standards: Bolam (1957) and Bolitho (1997) still relevant to assessing clinical practice/decision-making (not the Montgomery disclosure test).
Best interests (MCA): if lacking capacity, act in best interests; consider wishes/values, consult those close to patient, choose least restrictive option.
Advance decisions and proxy decision-makers: Advance Decision to Refuse Treatment (ADRT) is binding if valid/applicable; Lasting Power of Attorney (Health & Welfare) can decide within scope.
- ADRT refusing life-sustaining treatment must be written, signed, witnessed, and explicitly state it applies even if life is at risk.
Children: assess Gillick competence; otherwise consent from someone with parental responsibility. In emergencies, treat in best interests.

What to cover when consenting for anaesthesia (practical content)

Explain: proposed anaesthetic technique, what the patient will experience (induction, airway, monitoring, emergence, recovery).
Discuss reasonable alternatives: GA vs regional vs sedation; different regional blocks; awake vs asleep airway strategies where relevant.
Discuss material risks tailored to patient and procedure (not just a generic list).
- Common/less serious: sore throat, PONV, shivering, dental/lip trauma, bruising, pain at cannula site.
- Serious but rare: aspiration, awareness, anaphylaxis, major haemorrhage, stroke/MI, death, nerve injury (positioning/regional), visual loss (high-risk surgery).
- Regional/neuraxial-specific: failure, hypotension, post-dural puncture headache, infection, bleeding/epidural haematoma, nerve damage, LAST, urinary retention.
Blood products and transfusion: indication, risks, alternatives (cell salvage, tranexamic acid), and patient preferences (e.g., Jehovah’s Witness).
Postoperative pain plan: multimodal analgesia, opioids and side effects, PCA/epidural/nerve catheter, expectations and escalation.
Critical care: possibility of postoperative ventilation/HDU/ICU, especially in high-risk patients; align with ceilings of care and patient values.

Counselling approach (communication and shared decision-making)

Start with patient goals/concerns: “What matters most to you?”; explore fears (awareness, pain, nausea, needles, paralysis).
Use plain language; avoid jargon; use absolute risks where possible; check understanding (teach-back).
Risk communication: present balanced framing (benefits and harms), use frequencies (e.g., 1 in 100) rather than percentages, and compare options fairly.
Provide time and space: allow questions; offer written information/leaflets; consider preassessment clinic for complex cases.
Involve others appropriately: interpreter for language barriers (avoid using family as interpreter for complex consent), involve relatives with patient permission.
Anxiety and coercion: ensure voluntariness; manage pain/anxiety; avoid last-minute pressure where possible.

Documentation and forms (what to write)

Record: proposed technique, alternatives discussed, material risks discussed (patient-specific), questions asked, and patient decision.
If patient refuses recommended option: document capacity assessment, information provided, risks of refusal explained, and patient’s reasons/values if offered.
If using regional: document side, site, technique, risks discussed (including failure and nerve injury), and any patient-specific risk factors (anticoagulation, neuropathy).
Consent forms: signature supports evidence of process but does not replace contemporaneous notes.

Special situations

Emergency surgery: if capacity present, still seek consent; if lacking capacity and delay risks harm, treat in best interests; document rationale and discussions.
Sedation: consent must include intended depth, possibility of conversion to GA, and sedation risks (airway obstruction, hypoventilation, aspiration).
DNACPR and perioperative period: DNACPR does not automatically cease in theatre; discuss and document a perioperative plan (e.g., which interventions are acceptable).
Jehovah’s Witness / blood refusal: clarify which products are acceptable (RBC, platelets, plasma, fractions), cell salvage, and document clearly; involve senior clinicians early.
Lack of capacity with disagreement: involve family/LPA; consider IMCA if no family and serious decision; seek legal advice/Court of Protection if unresolved.
Chronic pain/opioid tolerance: counsel on realistic analgesic expectations, risk of poorly controlled pain, and plan (regional, ketamine, lidocaine, PCA settings).

Define valid consent and outline the essential components you must establish before proceeding with anaesthesia.

Structure your answer around voluntariness, capacity, and adequate information, then add documentation and the right to withdraw.

Valid consent requires: voluntary decision, patient has capacity, and is adequately informed.
Capacity is decision- and time-specific; presume capacity unless evidence otherwise.
Information: explain nature/purpose of anaesthesia, benefits, material risks, and reasonable alternatives (including no treatment where relevant).
Check understanding and allow questions; consent can be withdrawn at any time.
Document the discussion; signature is supportive evidence but not the consent itself.

Explain the Montgomery ruling and how it changes what you discuss when consenting a patient for anaesthesia.

Focus on patient-centred disclosure: material risks and reasonable alternatives, tailored to the individual patient.

Montgomery (2015): clinician must take reasonable care to ensure the patient is aware of material risks of the recommended treatment and of reasonable alternatives.
Materiality depends on the patient’s perspective: what a reasonable person in that patient’s position would consider significant, or what you know this patient would consider significant.
Practical implication: tailor discussion (e.g., professional voice user—risk of sore throat/hoarseness; anticoagulated patient—neuraxial bleeding risk; previous awareness—awareness risk).
You must discuss reasonable alternatives (e.g., GA vs spinal; nerve block vs opioids; awake fibreoptic vs asleep) and not present one option as the only choice without justification.

How do you assess capacity under the Mental Capacity Act 2005? Apply it to a patient who is in severe pain and distressed preoperatively.

State the 2-stage test and the 4 functional elements; then show how you would optimise conditions to support capacity.

MCA 2005: presume capacity; provide support to decide; unwise decisions do not equal lack of capacity.
Two-stage test: (1) impairment/disturbance of mind/brain? (2) does it render the person unable to make the specific decision now?
Functional test: can they understand, retain, use/weigh, and communicate the decision?
Severe pain/distress can impair ability to use/weigh information: treat pain/anxiety, give time, re-assess; consider postponing non-urgent decisions.
If still lacks capacity and urgent: proceed in best interests; document reasoning and discussions.

A patient refuses a spinal anaesthetic and requests GA, but you believe spinal is safer. How do you manage this?

Demonstrate shared decision-making, voluntariness, and documentation; avoid coercion.

Explore reasons for refusal (fear of needles/paralysis, prior bad experience, misconceptions) and address with clear information.
Explain comparative risks/benefits of GA vs spinal in this patient (including material risks) and reasonable alternatives (e.g., combined spinal-epidural, sedation with spinal, or GA with specific mitigations).
If patient has capacity and continues to refuse spinal, respect the decision; consent for GA with risk mitigation (aspiration prophylaxis, invasive monitoring, etc.).
If you believe GA is unacceptably risky and you cannot provide it safely, involve a senior colleague, consider postponement if elective, and document clearly.

What are the key risks you would discuss when consenting for an epidural for labour analgesia? How would you tailor this to the individual?

Cover common, serious/rare, and patient-specific risks; include failure and alternatives.

Explain benefits and alternatives (opioids, remifentanil PCA, spinal/CSE, non-pharmacological).
Common: inadequate block/failure, hypotension, itching (if opioids), shivering, urinary retention, motor block.
Less common/serious: accidental dural puncture and post-dural puncture headache; infection; bleeding/epidural haematoma; nerve injury; local anaesthetic systemic toxicity; high/total spinal (esp with CSE/top-ups).
Tailor: anticoagulation/platelet count, spinal pathology, sepsis, pre-existing neuropathy, difficult anatomy, patient priorities (e.g., desire to be mobile).
Document discussion and patient questions; ensure opportunity to decline without pressure.

A patient with an ADRT refusing ventilation presents for emergency laparotomy. How do you proceed?

Show understanding of ADRT validity/applicability, urgency, and escalation to seniors/legal advice where needed.

Assess whether ADRT is valid and applicable to the current circumstances (specificity, not withdrawn, not overridden by later LPA, applies to this scenario).
If it refuses life-sustaining treatment, confirm it meets formal requirements (written/signed/witnessed; explicit statement re life at risk).
If valid/applicable, it is legally binding: you must respect refusal even if death likely; discuss with surgical team and senior anaesthetist; consider whether surgery remains appropriate.
If uncertainty and time allows: urgent senior review, involve legal team; if immediate life-threatening and ADRT unclear, act in best interests and document rationale.

How do you consent a patient who does not speak English for a complex anaesthetic plan (e.g., awake fibreoptic intubation)?

Emphasise interpreter use, checking understanding, and documentation.

Use a professional interpreter (in-person/telephone/video); avoid using family members for complex consent where possible.
Explain the plan in steps, including what the patient will feel, why it’s recommended, alternatives, and material risks (e.g., discomfort, failure, conversion to GA, aspiration).
Use teach-back via interpreter to confirm understanding; allow time for questions.
Document interpreter details (name/ID), key points discussed, and patient’s decision.

Describe how you would counsel a high-risk patient for major surgery about postoperative critical care admission and potential outcomes.

Combine risk communication with values-based discussion and ceilings of care.

Explain why HDU/ICU may be needed (organ support, monitoring, ventilation) and what it involves (tubes/lines, sedation, delirium risk).
Discuss likely trajectory and uncertainties; provide absolute risk estimates if available (e.g., using validated tools) and clarify what matters to the patient (independence, cognition, time at home).
Discuss ceilings of care and DNACPR where appropriate; ensure decisions are documented and communicated to perioperative teams.
Avoid coercion; ensure time for reflection where possible; involve family with consent and consider shared decision-making with surgeons/intensivists.

What would you do if a patient withdraws consent in the anaesthetic room after you have started preparations (e.g., monitoring attached, cannula in situ)?

Demonstrate respect for autonomy, immediate safety, and calm de-escalation.

Stop and clarify what they are withdrawing consent for (anaesthesia, surgery, specific intervention) and why.
Assess capacity at that moment (pain/anxiety/drugs); address reversible factors; offer time and further explanation.
If capacitous refusal persists and not immediately life-saving: do not proceed; inform surgical team; arrange safe ongoing care and analgesia; document fully.
If immediate life-threatening emergency and patient lacks capacity: proceed in best interests; document rationale and team discussion.

Outline the key elements you would document after consenting a patient for a peripheral nerve block for postoperative analgesia.

Think: indication, alternatives, risks, side/site, patient factors, and decision.

Indication and expected benefits (analgesia, opioid-sparing, earlier mobilisation).
Alternatives discussed (systemic analgesia, neuraxial, local infiltration, no block).
Material risks: failure, bleeding/infection, nerve injury, LAST, motor weakness/falls risk, pneumothorax (if relevant), catheter risks if used.
Laterality and site; patient-specific risks (anticoagulants, neuropathy, diabetes); and patient questions/decision.
