The Palliative Performance Scale (PPS) is an 11-point, 0%-to-100% clinician-assessed functional-status tool used to track decline and estimate prognosis in patients with advanced or life-limiting illness. This page covers the five domains it scores, how “leftward precedence” resolves conflicting domain ratings, the hospice-eligibility thresholds clinicians actually use, and how it relates to the Karnofsky Performance Scale it was adapted from. For related functional and clinical-risk tools, see CASRAI’s Johns Hopkins Fall Risk Assessment Tool and Hospice Supply Checklist pages.
What the PPS is, and who built it
The PPS was developed by Victoria Hospice (Anderson et al.) as a palliative-care-specific adaptation of the older Karnofsky Performance Scale, which was originally built for oncology patients receiving active treatment rather than patients transitioning to comfort-focused care. The PPS keeps the Karnofsky Scale’s 0-100% structure but reframes the descriptors around the functional domains that actually change as a patient approaches the end of life — ambulation, self-care, and intake decline in a fairly predictable sequence that the Karnofsky Scale’s original oncology-treatment framing wasn’t built to capture. The current standard version is PPSv2, which refined the wording of several score levels from the original PPS to improve inter-rater agreement.
The five domains and score structure
The PPS scores from 100% (fully healthy and active) down to 0% (death) in 10-point increments, across five domains assessed together:
| Domain | What it measures |
|---|---|
| Ambulation | Ranges from full mobility to totally bed-bound |
| Activity & evidence of disease | Capacity to maintain normal work or hobbies, weighed against how much disease is evident |
| Self-care | Independence in bathing, dressing, and eating, through to needing total assistance |
| Intake | Nutritional and fluid intake, from normal through reduced to minimal sips |
| Level of consciousness | Ranges from fully alert to drowsy, confused, or unresponsive |
Scoring: why “leftward precedence” matters
A patient rarely sits at exactly the same functional level across all five domains simultaneously. When domains disagree, PPS scoring uses “leftward precedence”: the assessor reads across the five domain columns for a given score row and gives priority to whichever domain is worse, moving from ambulation (read first, given the most weight) toward level of consciousness (read last). In practice, this means a patient who is fully ambulatory but confused is generally scored lower than the confusion domain alone might suggest, because ambulation is weighted more heavily — a scoring detail that matters for chart consistency across raters and is easy to get backwards without reading the reference card carefully.
Hospice eligibility and prognosis
PPS scores correlate with survival time and are commonly used, alongside diagnosis-specific clinical criteria, in hospice-eligibility discussions. Widely cited working thresholds are a PPS of 70% or below for cancer diagnoses and 50% or below for many non-cancer diagnoses (e.g., dementia, heart failure) as a point to evaluate hospice appropriateness — though the PPS score alone is never sufficient for a Medicare hospice-eligibility determination on its own; it is one input alongside the disease-specific Local Coverage Determination criteria a hospice’s medical director applies under the Medicare Hospice Benefit (42 CFR Part 418). A declining PPS trajectory over serial assessments is generally more clinically informative than any single score.
Frequently asked questions
What is the Palliative Performance Scale?
An 11-point, 0-100% clinician-assessed tool (Victoria Hospice, adapted from the Karnofsky Performance Scale) that measures functional decline across ambulation, activity/disease evidence, self-care, intake, and level of consciousness, used to track status and inform prognosis in palliative and hospice care.
What PPS score qualifies for hospice?
Commonly cited working thresholds are 70% or below for cancer diagnoses and 50% or below for many non-cancer diagnoses, but PPS alone never determines Medicare hospice eligibility — it is one input alongside disease-specific clinical criteria applied by the hospice’s medical director.
How is the Palliative Performance Scale calculated?
The assessor rates the patient across five domains (ambulation, activity/evidence of disease, self-care, intake, level of consciousness) and assigns the overall percentage using “leftward precedence” — giving priority to the domain read first (ambulation) when domains disagree, rather than averaging them.
How is the PPS different from the Karnofsky Performance Scale?
Both use a 0-100% scale, but the PPS was purpose-built for palliative and hospice populations, reframing its descriptors around the ambulation, self-care, and intake decline typical at end of life, rather than the Karnofsky Scale’s original framing around active oncology treatment.
