Palliative care is not hospice

When a clinician first says the words "palliative care", a lot of families hear something else. They hear that treatment is being withdrawn, that the situation is worse than they were told, or that someone has decided their parent is dying.

That misunderstanding is common enough to be a clinical problem in itself, because it causes families to refuse something that the evidence suggests helps.

The two are not the same thing

A 2022 review in the Journal of Family Medicine and Primary Care sets out the distinction. Hospice is a specific form of care with an eligibility requirement: patients become eligible "when their life expectancy is less than six months", and it requires certification of terminal illness by two physicians.

Palliative care has no such requirement. It is available to people with a "major illness; chronic complex diseases that negatively affect the quality of life", regardless of prognosis. The World Health Organization's position, as the review notes, is that it "should be started as early as possible in the course of any chronic, ultimately fatal illness".

The clearest practical difference is what happens to treatment. In palliative care, "the use of life-prolonging medications is encouraged". In hospice, the review states, "no life-prolonging medications are used".

So palliative care runs alongside treatment aimed at the disease. Someone can be receiving chemotherapy, dialysis or heart failure treatment and palliative care at the same time, and that is the intended design rather than a contradiction.

What it actually is

In practice, palliative care is a team focused on everything the disease is doing to the person that is not the disease itself: pain, breathlessness, nausea, exhaustion, appetite, sleep, anxiety, and the practical and emotional weight falling on the family.

It is worth being blunt about why this matters for an older person with several chronic conditions. The specialists are each managing an organ. The palliative team is managing the experience of being the person all those organs belong to, which is often the thing nobody has been assigned.

What the evidence shows, and its limits

The most careful summary is a 2016 systematic review and meta-analysis in JAMA by Kavalieratos and colleagues.

It found palliative care "was associated with statistically and clinically significant improvements in patient QOL at the 1- to 3-month follow-up", an improvement of 11.36 points on the FACIT-Pal quality of life scale, along with a clinically significant reduction in symptom burden over the same period.

Now the honest part. When the analysis was restricted to the trials at lowest risk of bias, the quality of life improvement shrank to 4.94 points, which the authors describe as "statistically significant but not clinically important", and the reduction in symptom burden was no longer statistically significant.

On survival, there was "no association between palliative care and survival". Caregiver outcomes were inconsistent across studies.

So the fair reading is: good evidence of benefit to quality of life and symptoms, weaker once you restrict to the most rigorous trials, no evidence that it shortens life, and no reliable evidence yet on what it does for the family. Anyone telling you palliative care is proven to extend life is overstating it. So is anyone implying it hastens death.

What to ask

• • Is this palliative care or hospice? They are different, and the answer determines whether treatment continues.
• • Does accepting it change any of the current treatment?
• • What specifically would the team help with, and how often would we see them?
• • Can they come to the house?
• • Can we try it and stop if it is not helping?

That last question is worth asking out loud, because families often assume the decision is irreversible and final. Framed as something to try, it becomes a much smaller decision than it feels.

The honest summary

Palliative care is symptom and quality of life care that can run alongside treatment, at any stage of a serious illness. Hospice is a distinct thing with a six month prognosis requirement and a different approach to life-prolonging medication. Hearing the first and understanding the second is one of the more consequential misunderstandings in serious illness, and it is worth clearing up before the conversation gets harder.
