End-of-Life Care and Advance Care Planning — Written Clinical Reasoning

SAQ 1 — Advance Care Planning and Goals of Care in End-Stage Heart Failure (20 marks, 30 minutes)

Prompt: Outline your integrated approach to this 82-year-old man with end-stage heart failure and chronic kidney disease admitted with a decompensation, including: (a) the trigger for advance care planning and the evidence it improves outcomes; (b) the structure of the goals-of-care conversation; (c) the content of an advance care plan; (d) the proposed ceiling of treatment; and (e) the principles of prognosis discussion. [1]

Model Answer

(a) The trigger for advance care planning and the evidence (4 marks): [1]

This patient triggers a "no" answer to the Surprise Question — "Would I be surprised if this patient died in the next 12 months?" He has end-stage heart failure with NYHA IV symptoms and repeated decompensations, which carries a one-year mortality in excess of 30 per cent, compounded by chronic kidney disease. The Surprise Question is the simplest and most widely taught screening tool for end-of-life need, and a "no" answer is the trigger to initiate advance care planning now, while he has capacity [1].

The evidence that advance care planning improves outcomes is strong. The Detering randomised controlled trial of facilitated advance care planning in medical inpatients aged 80 and over (BMJ 2010) showed that end-of-life wishes were far more likely to be known and respected in the intervention group (86 per cent versus 30 per cent), with reduced stress, anxiety and depression in bereaved relatives and higher family satisfaction [2]. The Wright cohort study in advanced cancer (JAMA 2008) showed that end-of-life discussions were associated with less aggressive care in the final week (less ventilation, less resuscitation, less ICU, more and earlier hospice) and no increase in depression or distress; more aggressive care was associated with worse quality of life near death and more major depressive disorder in bereaved caregivers [3]. The Brinkman-Stoppelenburg systematic review (Palliat Med 2014) confirmed that advance care planning reduces life-sustaining treatment at the end of life, increases hospice and palliative care use, and improves concordance between preferences and care delivered, with "complex" facilitated planning outperforming a directive alone [1]. The practical message is that a conversation, documented and accessible, changes what happens to the patient.

(b) Structuring the goals-of-care conversation (4 marks): [1]

I would use a structured conversation combining the goals-of-care framework with the SPIKES protocol for delivering difficult news [6][7]. Setting: a quiet, private room, with the patient and the family members he wishes present, the senior clinician and a nurse, enough time, and no interruptions. Perception: I begin by asking what he and his family understand about his heart failure and its trajectory — "Tell me what you understand about your heart condition and how it has been going." This establishes the baseline and often surfaces misconceptions. Invitation: I ask how much detail he wants about the prognosis and the options. Knowledge: I give honest information in plain language — that his heart failure is advanced and progressive, that the repeated admissions indicate the disease is no longer responding well to treatment, and that this is the time to think together about what matters most and what he would want if he became more unwell. Empathy: I acknowledge the emotion — this is hard news — and I stay with it, allowing silence. Summarise and Strategise: I summarise, check understanding, and agree the next steps, including a follow-up conversation.

I would specifically use the questions of the Serious Illness Conversation Guide (Ariadne Labs) to elicit his values and goals [7]: what matters most to him; what he understands about his illness; what he is willing and not willing to go through; what he would consider an acceptable outcome; who he wants to make decisions if he cannot. I would address the guilt that families sometimes feel when a comfort-focused plan is proposed, and reframe comfort as an act of care consistent with his values.

(c) The content of an advance care plan (4 marks): [1]

The advance care plan documents, from the conversation: (1) his understanding of his illness and prognosis; (2) his values and goals — what makes life worth living, what outcomes he would find unacceptable (prolonged unconsciousness, dependence on machines, loss of the ability to recognise family); (3) his treatment preferences — what he would and would not want, specifically addressing cardiopulmonary resuscitation, mechanical ventilation, artificial hydration and nutrition, dialysis, antibiotics in the dying phase, and admission to intensive care; (4) his preferred place of death (home, hospice, hospital, residential aged-care facility); (5) the appointment and preparation of a substitute decision-maker (an enduring guardian) who understands his values and will speak for him when he loses capacity; and (6) the date and the plan for review. If he wishes, I would support him to complete a formal advance care directive that legally documents his refusal of specific treatments — a valid refusal is binding and must be honoured even after capacity is lost. The plan is documented in the medical record and on the hospital's goals-of-care / medical goals-of-care form, communicated to the ward team, the general practitioner, and (if he agrees) his residential facility. [1]

(d) The proposed ceiling of treatment (4 marks): [1]

I would propose, in discussion with the patient and family, a ceiling of ward-based active treatment with no escalation to intensive care and no cardiopulmonary resuscitation, focused on symptom control and quality of life. Within that ceiling he continues to receive active treatment: optimal guideline-directed medical therapy for the heart failure (the disease-directed therapy is not stopped by a ceiling — the ceiling sets the upper limit of escalation in deterioration), a trial of intravenous diuretics for a decompensation, supplemental oxygen for symptomatic hypoxaemia, and treatment of reversible precipitants (anaemia, infection, arrhythmia, ischaemia). What the ceiling explicitly excludes is admission to intensive care, mechanical ventilation, inotropic support in the event of cardiogenic shock with no reversible cause, and cardiopulmonary resuscitation in the event of cardiac arrest. [1]

The defining principle is that a ceiling is not a withdrawal of care. The patient continues to receive active treatment and full symptom control within the agreed limits — the phrase is do not resuscitate, but do not abandon [8]. Withholding and withdrawing life-sustaining treatment are ethically and legally equivalent, and there is no obligation to provide futile treatment; where there is genuine prognostic uncertainty, I would start an intervention as a trial and review. I would document the ceiling as a medical order, communicate it to the team, the ambulance service and the GP, and review it at each admission and each major functional decline. I would involve the palliative care team for symptom control and family support, and I would not abandon the disease-directed heart failure therapy, which improves symptoms and prognosis independent of the ceiling.

(e) The principles of prognosis discussion (4 marks): [1]

Discussing prognosis is a clinical skill and an ethical duty. The principles [7]: ask before telling — find out what the patient wants to know, and match the answer to his preference (some want a number, some a range, some only the gist); be honest but humane — give the realistic picture without false hope and without stripping all hope, framed as "hope for the best, prepare for the worst"; give a range, not a point estimate — "weeks to a few months rather than years" is more useful and more honest than a false-precision number, and acknowledges the irreducible uncertainty of individual prognosis; acknowledge uncertainty explicitly — "I cannot give you an exact number, and I will be honest with you as we learn more" maintains trust; and connect prognosis to goals — once the trajectory is understood, ask what matters most with the time that remains, which is the bridge from prognosis to the advance care plan. I would avoid the common errors of either false reassurance (which destroys trust when the prognosis declares itself) or brutal honesty without support (which abandons the patient to despair).

SAQ 2 — Management of the Dying Patient (10 marks)

Prompt: A 77-year-old woman with metastatic ovarian cancer is now in the last days of life on the ward. She is drowsy, no longer swallowing, and has Cheyne-Stokes respiration. Her family is at the bedside. Outline your structured care bundle for the dying patient, including: (a) recognition and communication; (b) anticipatory prescribing (the Just In Case Box); (c) comfort measures; and (d) family and bereavement support. [1]

Model Answer

(a) Recognition and communication (2 marks): [1]

The cardinal signs of the dying phase are present — reduced consciousness, reduced oral intake with loss of swallowing, and the changing breathing pattern of Cheyne-Stokes respiration. I would recognise the dying phase, communicate it to the family with honesty and compassion (explaining the signs, that she is comfortable, and that they can be present), document the recognition, and switch the goal of care from curative or stabilising to anticipatory symptom-focused care. I would stop non-essential investigations and monitoring that no longer change the plan. [1]

(b) Anticipatory prescribing — the Just In Case Box (4 marks): [1]

I would prescribe the four core subcutaneous medicines in advance, so that the nurse can give symptom relief immediately at any hour. Morphine for pain or refractory breathlessness: 2.5 to 5 mg subcutaneously every 2 to 4 hours as needed in the opioid-naive patient (or the calculated equivalent if she is already on opioids), with conversion to a continuous subcutaneous infusion via syringe driver if repeated PRN doses are required. Midazolam for agitation or anxiety: 2.5 to 5 mg subcutaneously every 2 to 4 hours as needed, or 10 to 30 mg over 24 hours by syringe driver. Glycopyrronium for noisy respiratory secretions (if they develop): 200 micrograms subcutaneously every 2 to 4 hours as needed, or 600 to 1200 micrograms over 24 hours (alternatively hyoscine butylbromide 20 mg subcutaneously as needed, or 40 to 80 mg over 24 hours). Levomepromazine for nausea or refractory agitation: 6.25 to 12.5 mg subcutaneously every 8 to 12 hours as needed, or 12.5 to 25 mg over 24 hours by syringe driver. [1]

Key principles: the subcutaneous route is preferred because intravenous access is hard, intramuscular injections are painful, and she cannot swallow; a continuous subcutaneous infusion (syringe driver) is used when PRN doses are repeated or for continuous symptom control, with PRN top-ups still available for breakthrough; for breathlessness, low-dose morphine relieves dyspnoea without harmful respiratory depression, and routine supplemental oxygen for the non-hypoxaemic breathless patient offers no benefit over room air (Abernethy trial) [5]. I would also review and stop non-essential medications (statins, oral hypoglycaemics, disease-modifying drugs, antiplatelets), while continuing analgesia, antiemetics, anticonvulsants and symptom-relief drugs.

(c) Comfort measures (2 marks): [1]

Mouth care is a basic dignity — the dying patient breathes through the mouth and the mucosa dries; I would perform regular mouth care with water on a swab, lip balm, and removal of poorly fitting dentures. Pressure area care: reposition for comfort, use a pressure-relieving mattress, keep the skin clean and dry, manage incontinence with pads or a urinary catheter if she is distressed by wetness. I would continue only the monitoring that guides comfort, and stop blood tests and imaging that no longer change the plan. [1]

(d) Family and bereavement support (2 marks): [1]

I would communicate proactively with the family — explain the dying process, that she is comfortable, and that they can be present; offer them the chance to touch and speak to her and to perform rituals that matter; respect culture and faith and ask about religious practices around death; screen for spiritual distress and offer a chaplain or spiritual carer; and prepare the family for bereavement. After the death I would ensure a dignified, peaceful environment, communicate the death in person with empathy and time, offer a bereavement review and condolence contact, and screen at-risk families (those with a previous psychiatric history, the death of a child, a traumatic death, social isolation, or high pre-death caregiver burden) for prolonged grief disorder at 6 to 12 months, referring for specialist grief-focused therapy where the diagnosis is suspected [9]. I would also debrief the staff, as caring for dying patients is hard.
