Advance Directive for Terminal Illness and Palliative Care in QLD

Why a Terminal Diagnosis Changes the Conversation

Most people who create an Advance Health Directive do it in abstract — planning for a "what if" scenario that might be years or decades away. A terminal diagnosis collapses that timeline. Suddenly the questions aren't hypothetical: will you accept mechanical ventilation if your condition deteriorates? Do you want tube feeding if you can no longer swallow? Should the medical team attempt resuscitation if your heart stops?

Queensland's Advance Health Directive (Form 4) is designed to handle these situations, but the document you might have created at 55 during a routine estate planning exercise may not address the specific treatment decisions you're now facing at 72 with a stage IV cancer diagnosis. Revisiting and updating the AHD after a terminal diagnosis ensures your documented preferences match your actual clinical situation.

How Terminal Illness Activates AHD Provisions

Under the Powers of Attorney Act 1998, certain life-sustaining treatment refusals in an AHD only take effect when specific clinical thresholds are met. A direction to withdraw life-sustaining measures doesn't operate unless:

• The patient has a terminal illness with no reasonable prospect of recovery, and the treating doctor and another doctor agree that death is expected within one year, or
• The patient is in a persistent vegetative state with no reasonable prospect of cognitive recovery, or
• The patient is in a permanent coma with no reasonable prospect of regaining consciousness, or
• The patient has an illness or injury of such severity that they will permanently require life-sustaining treatment to survive

This means an AHD that says "I refuse mechanical ventilation" won't necessarily be followed if the patient's current condition is treatable or reversible. The treating team evaluates whether the clinical threshold has been reached before the refusal becomes operative.

For someone with a confirmed terminal diagnosis, that diagnosis does not by itself establish that the statutory threshold is met — and the treating team still needs clear, specific language in the AHD to know exactly which treatments to withhold and under what circumstances. General phrases like "no extraordinary measures" leave too much room for clinical interpretation.

Advance Care Planning in Palliative Care

When a patient transitions to palliative care, the treatment focus shifts from curative to comfort. The palliative care team works with the patient and family to establish a care plan that manages symptoms — pain, nausea, breathlessness, anxiety — rather than attempting to cure the underlying disease.

An AHD complements palliative care by documenting specific treatment boundaries. Common decisions to address include:

• Resuscitation: Whether CPR should be attempted if the heart stops (in palliative contexts, most patients and families choose not-for-resuscitation, as CPR rarely results in meaningful recovery at end of life)
• Mechanical ventilation: Whether intubation and ventilation should be initiated
• Artificial nutrition and hydration: Whether feeding tubes should be inserted if the patient can no longer eat or drink
• Antibiotics: Whether infections should be treated aggressively or managed for comfort only
• Hospital transfer: Whether the patient should be transferred to hospital from home or an aged care facility, or whether treatment should continue in the current setting

The palliative care team at a Queensland hospital or hospice will typically ask whether the patient has an AHD and will record treatment preferences in an Acute Resuscitation Plan (ARP) that aligns with the directive.

Organ and Tissue Donation

An Advance Health Directive can include your wishes about organ and tissue donation, but Queensland treats donation consent through a separate pathway.

The Australian Organ Donor Register (managed by Services Australia) is the primary mechanism for recording donation wishes nationally. Registering there ensures that if donation becomes a possibility after death, the DonateLife network knows your documented preference.

An AHD can reinforce your donation wishes and flag them to the treating team, but the AHD alone doesn't replace registration on the national register. Practically, the clinical team contacts DonateLife when a patient is at or near end of life and donation might be feasible. DonateLife then checks the register and consults the family.

The important point: even with a registered preference to donate, the family is always consulted. In practice, families very rarely override a documented wish to donate — but they sometimes override an undocumented one because they're unsure what the person wanted. Registering on the national donor register AND documenting your wishes in your AHD AND telling your family directly gives the strongest coverage.

After a Diagnosis: Updating vs Creating

If you already have an AHD, a terminal diagnosis is the trigger to review it. Read through your existing clinical directions and ask whether they accurately reflect your preferences given what you now know about your condition and prognosis. If they don't, revoke the existing AHD and execute a new one; creating a fresh document is generally cleaner in Queensland's system.

If you don't yet have an AHD, the diagnosis itself creates urgency. The document requires a doctor's capacity certificate (Section 5 of Form 4) and an independent witness — both of which take coordination and time. If cognitive capacity is already declining, the window to execute a valid AHD narrows quickly.

The doctor consultation for Section 5 is also a natural moment to discuss your specific treatment preferences in clinical terms. A GP or oncologist who understands your diagnosis can help you phrase your directions precisely enough to avoid the ambiguity problems that lead to clinical overrides.

For the full process — from clinical phrasing templates to the signing protocol to document distribution — the Queensland Advance Directive & Living Will Kit covers every step of creating or updating an AHD after a terminal diagnosis.
