Advance Directive Palliative Care and Terminal Illness UK
A Terminal Diagnosis Changes the Planning Equation
For someone without a specific diagnosis, advance care planning is precautionary — preparing for a future that may or may not arrive. After a terminal diagnosis, it becomes operational. The treatments you might need to refuse are no longer hypothetical. The clinical team managing your care needs concrete, enforceable instructions.
The window for creating legally valid documents is still open, but it has a visible endpoint. Diseases that affect cognition — brain tumours, certain cancers with cerebral involvement, conditions requiring sedation — can reduce capacity faster than expected. The time to plan is when you can still demonstrate decision-specific capacity, not when treatment complications have begun.
The Core Documents for End of Life in England
Advance Decision to Refuse Treatment (ADRT). The legally binding instrument under the Mental Capacity Act 2005. After a terminal diagnosis, the ADRT should be specific to your condition and prognosis. Generic refusals ("no treatment if I have no quality of life") are far less useful than condition-specific refusals grounded in your clinical team's assessment of likely treatment pathways.
For a cancer diagnosis, this might mean refusing chemotherapy if the tumour becomes treatment-resistant, refusing CPR if your prognosis is weeks rather than months, or refusing clinically assisted nutrition and hydration if you enter a comatose state. Your oncologist or palliative care consultant can help you identify the realistic treatment decision points.
Lasting Power of Attorney for Health and Welfare. Appoints someone to make medical decisions if you lose capacity. Must be registered with the OPG before it can be used — and registration takes 8 to 12 weeks for online applications, longer for paper. After a terminal diagnosis, registering immediately is essential.
Advance Statement. A non-binding document that records your preferences, values, and wishes — where you want to die, what comfort measures matter to you, your spiritual or religious needs, who you want present. Clinical teams must take these into account when making "best interests" decisions, even though they are not legally bound by them.
ReSPECT form. If your care involves NHS services, your clinical team may create a ReSPECT form that summarises your emergency treatment preferences. This is a clinical document, not a legal one. It should reference your ADRT rather than replacing it.
Integrating an ADRT With Palliative Care
Palliative care focuses on comfort, symptom management, and quality of life rather than cure. An ADRT does not conflict with palliative care — in fact, the two align well. The ADRT specifies which treatments you refuse; palliative care ensures you receive the comfort and symptom management that continues regardless of what you have refused.
Key points to coordinate with your palliative care team:
Pain relief is never refused by an ADRT. Under the Mental Capacity Act 2005 Code of Practice, palliative pain management and comfort care are considered "basic care" that cannot be refused in advance. Your ADRT can refuse artificial ventilation, tube feeding, and CPR while still receiving full palliative pain management, sedation for distress, and all comfort measures.
The double-effect principle. If pain relief at end of life (such as opioid medication) carries a risk of shortening life as a side effect, this is ethically and legally permissible under current medical practice in England. Your ADRT can include a statement confirming that you accept this risk — but this is not usually necessary, as the principle is well established in clinical practice.
Hospice and home care settings. If you prefer to die at home or in a hospice rather than in hospital, record this in your Advance Statement (not the ADRT, which only covers treatment refusals). Communicate it to your palliative care team, your GP, and your Health and Welfare attorney. Note that this preference is not legally binding — if a medical emergency occurs, paramedics may still take you to hospital unless a DNACPR/ReSPECT form is in place and accessible.

After a Cancer Diagnosis — Specific Considerations
Cancer patients face particular advance planning challenges because the disease course can shift rapidly. A patient who is responding well to treatment may want aggressive care continued. The same patient, weeks later, may want to transition to comfort measures only.
The ADRT can be written to account for this:
- Specify refusals that activate only after a defined clinical threshold — for example, "I refuse further chemotherapy if my oncologist determines the cancer is no longer responding to treatment"
- Include a refusal of CPR conditional on prognosis — "I refuse CPR if my clinical team assesses my prognosis as weeks rather than months"
- Refuse intensive-care admission while accepting ward-level care, or refuse intubation while accepting non-invasive oxygen support
This conditional structure requires discussion with your clinical team to ensure the conditions are clinically meaningful and can be assessed objectively.
The Timing Pressure
For any terminal illness, the constraint is capacity rather than paperwork. The ADRT can be written and signed in an afternoon. The LPA takes 8 to 12 weeks to register with the OPG. If capacity is expected to decline within that window, starting the LPA registration immediately — even before the ADRT is finalised — is the priority.
Our England Advance Directive guide covers the complete end-of-life document set for England, including condition-specific ADRT phrasing templates, the palliative care integration framework, and the step-by-step LPA registration process with timing guidance for different diagnosis timelines.
