Mastering Palliative Care Symptom Management for MRCP PACES

Why Palliative Care is High-Yield in MRCP PACES

Palliative care scenarios appear frequently in MRCP PACES, particularly in Stations 2 and 5, where candidates must demonstrate not only clinical knowledge but also the ability to manage complex symptoms in patients with life-limiting illnesses. Examiners assess whether you can deliver holistic, patient-centred care while applying evidence-based guidelines. A common pitfall is focusing solely on communication skills while neglecting the pharmacological and clinical management of distressing symptoms. This guide bridges that gap, equipping you with the knowledge to confidently manage palliative symptoms under exam pressure.

Core Symptom Domains You Must Master

1. Pain Management in Palliative Care

Pain is the most commonly encountered symptom in palliative care PACES scenarios. You must be fluent in the WHO analgesic ladder and understand how to escalate treatment appropriately.

Key Principles:

• Assess pain using a structured approach (site, character, severity, exacerbating/relieving factors)

• Distinguish between nociceptive (somatic/visceral) and neuropathic pain, as this guides therapy

• Prescribe according to the WHO ladder:

  • Step 1: Non-opioid (e.g., paracetamol, NSAIDs with PPI cover)

  • Step 2: Weak opioid (e.g., codeine, tramadol)

  • Step 3: Strong opioid (e.g., morphine, oxycodone)

Opioid Conversion Essentials:

Exam Tip: Always prescribe a breakthrough dose equal to 1/6th to 1/10th of the total 24-hour opioid dose, given every 1–2 hours PRN.

Neuropathic Pain:

If pain has a neuropathic component, add adjuvants:

• Gabapentin (300mg starting dose, titrate)

• Amitriptyline (10–25mg nocte)

• Consider nerve blocks or radiotherapy for specific indications

2. Nausea and Vomiting

This is a frequently tested area. The key is to identify the underlying cause and select an antiemetic that targets the relevant receptor pathway.

Mechanism-Based Antiemetic Selection:

High-Yield Point: In bowel obstruction, combine cyclizine with an antisecretory agent (octreotide 200–600mcg/24h SC or hyoscine butylbromide 60–120mg/24h SC) to reduce colic and vomiting.

3. Breathlessness (Dyspnoea) in Advanced Disease

Breathlessness is devastating for patients and frequently appears in PACES consultations. Your management must address both the reversible causes and the symptomatic relief.

Management Framework:

Treat reversible causes:

• Pleural effusion → aspiration/drainage

• Pulmonary oedema → diuretics

• Anaemia → transfusion (if appropriate in goals of care)

• Infection → antibiotics (if aligned with patient wishes)

• Bronchospasm → bronchodilators

Symptomatic management:

• Low-dose oral morphine (2.5mg every 4 hours) — reduces ventilatory drive and the distressing sensation of breathlessness without significant respiratory depression when used appropriately

• Oxygen — only if hypoxic (SpO₂ < 90%); not beneficial for non-hypoxic dyspnoea

• Benzodiazepines (lorazepam 0.5–1mg PRN) — for anxiety-associated dyspnoea

• Fans and upright positioning — simple non-pharmacological measures

• Breathlessness clinics and CBT-based strategies for ongoing support

Exam Trap: Do NOT say 'oxygen for everyone with breathlessness.' Examiners will challenge this. Only prescribe oxygen for the hypoxic patient.

4. Terminal Agitation and Restlessness

This is a critical area where candidates often falter. Terminal agitation requires prompt recognition and management, as it causes immense distress to patients and families.

Causes of Terminal Agitation:

• Urinary retention

• Constipation / faecal impaction

• Pain

• Delirium (metabolic, infective, drug-induced)

• Fear and anxiety

• Spiritual distress

Management:

Address reversible causes first. Then:

• Haloperidol 0.5–2mg SC every 2–4 hours (for delirium)

• Midazolam 10–20mg/24h SC infusion (for severe agitation/anxiety)

• Levomepromazine 12.5–25mg SC od-bd (for resistant cases)

Critical PACES Point: Always distinguish terminal agitation from terminal restlessness due to pain. If a patient is agitated and on opioids, consider whether they are in uncontrolled pain rather than simply sedating them further.

5. Respiratory Tract Secretions ('Death Rattle')

This occurs in the last hours to days of life and is distressing for families. Understanding this is essential for PACES.

Management:

• Hyoscine hydrobromide 400mcg SC every 2–4 hours (antisecretory)

• Hyoscine butylbromide 20mg SC every 4–6 hours (if sedation undesirable)

• Glycopyrronium 200mcg SC every 6–8 hours

• Position the patient semi-prone and explain to the family that the patient is likely unconscious and not distressed by the secretions

Key Communication Point: Reassure the family that noisy breathing does not mean the patient is suffering. This is one of the most important counselling points in terminal care.

Common PACES Scenarios in Palliative Care

Scenario 1: Metastatic Cancer with Uncontrolled Pain

A 68-year-old woman with metastatic breast cancer is on 30mg oral morphine twice daily but still has breakthrough pain 3–4 times per day. She rates her pain as 7/10.

What you must address:

1. Total daily morphine dose = 60mg

2. Breakthrough dose = 60 ÷ 6 = 10mg oral morphine PRN

3. Assess pain type — is it bone pain? Consider adding an NSAID or bisphosphonate

4. Escalate — if breakthrough pain is frequent, increase the regular dose by 30–50%

5. Consider fentanyl patches or PCA if oral route is problematic

Scenario 2: Bowel Obstruction in Advanced Ovarian Cancer

A 72-year-old woman with advanced ovarian cancer presents with colicky abdominal pain and vomiting.

Management plan:

1. Cyclizine 50mg SC tds (antiemetic for obstruction)

2. Hyoscine butylbromide 60–120mg/24h SC infusion (for colic)

3. Octreotide 200–600mcg/24h SC infusion (reduces secretions)

4. Diamorphine SC (if opioid-naïve) or continue current opioid converted to SC equivalent

5. Consider dexamethasone 6–16mg SC od (may reduce peritumoural oedema)

6. NG tube for decompression if vomiting persists

7. Discuss surgical options if appropriate (single-level obstruction with good performance status)

Scenario 3: Syringe Driver Prescription

Examiners may ask you to convert a patient's oral medications to a continuous subcutaneous infusion (syringe driver) when the oral route is lost.

Conversion Example:

Compatibility Check: Remember that cyclizine is incompatible with many drugs in a syringe driver (including diamorphine). Check a palliative care formulary or use a dedicated compatibility resource.

The 'Liverpool Care Pathway' Controversy and Modern Individualised Care Plans

You should be aware that the Liverpool Care Pathway (LCP) was phased out in the UK in 2014 following concerns about poor implementation. Modern palliative care emphasises individualised care plans for the dying patient.

Key elements of a good care plan for the dying patient:

1. Recognition of dying — documented with rationale

2. Communication with patient (if possible) and family

3. Symptom assessment — regular re-assessment every 4 hours

4. Anticipatory prescribing ('just in case' box)

5. Spiritual and psychological support

6. Regular review by the medical team

Examiners' Favourite: 'What would you prescribe in anticipation of common symptoms at the end of life?' — Know the standard anticipatory ('just in case') medications.

Standard Anticipatory Prescribing:

Structuring Your PACES Palliative Care Consultation

When presenting to the examiner, follow this structure:

1. Clinical Summary (30 seconds)

'This is a 70-year-old man with metastatic lung cancer presenting with worsening breathlessness and pain, consistent with disease progression.'

2. Key Problems Identified (30 seconds)

'His main problems are:

• Uncontrolled pain (likely mixed nociceptive and neuropathic)

• Breathlessness with hypoxia

• Psychological distress

• Advance care planning needs'

3. Management Plan (60–90 seconds)

'I would:

• Optimise analgesia by increasing his regular morphine and prescribing appropriate breakthrough doses

• Add a neuropathic agent for the neuropathic component

• Commence low-dose morphine for breathlessness and consider oxygen given his hypoxia

• Refer to the specialist palliative care team

• Discuss advance care planning, including resuscitation status and preferred place of death

• Offer psychological and spiritual support'

4. Ongoing Care and Family Communication

'I would ensure regular reassessment, provide a named key worker, and communicate openly with the family about the prognosis and goals of care.'

Common Mistakes That Cost Candidates Marks

1. Not knowing opioid conversion ratios — examiners will test this directly

2. Prescribing oxygen for all breathlessness — only for hypoxic patients

3. Failing to address psychological and spiritual needs — palliative care is holistic

4. Not knowing the standard 'just in case' medications — this is fundamental knowledge

5. Over-sedating without reviewing — always reassess the cause of agitation

6. Not involving the specialist palliative care team — MDT approach is essential

7. Forgetting to discuss DNACPR/advance care planning — examiners expect senior-level thinking

Key Resources for Revision

1. ** palliativedrugs.com** — Essential for drug compatibility and dosing

2. NICE Guideline NG31 — Care of dying adults in the last days of life

3. BNF — Palliative care section with conversion tables

4. Scottish Palliative Care Guidelines — Excellent, practical, and free online

5. 'Oxford Handbook of Palliative Care' — Comprehensive reference for exam revision

Final Tips for Exam Day

• Practise opioid conversion until it is automatic — you will be tested on this

• Memorise the standard anticipatory prescribing chart — it appears in nearly every palliative care station

• Demonstrate empathy — examiners are watching your human qualities as much as your knowledge

• Always mention the MDT — specialist palliative care nurses, chaplaincy, social workers

• Know when to escalate to inpatient palliative care — recognise when community management is insufficient

Palliative care in PACES rewards candidates who combine solid pharmacological knowledge with genuine compassion. Master both, and you will approach any palliative scenario with the confidence of a competent registrar.

Good luck with your PACES preparation. Remember: every patient encounter is an opportunity to demonstrate not just what you know, but who you are as a doctor.
