Which statement best describes the Palliative Performance Scale (PPS) in terms of its rating and purpose?

• A. PPS is an observer-rated tool that correlates with survival.
• B. Karnofsky is an observer-rated tool.
• C. ADL measures survival.
• D. IADL measures survival.

Answer: (A)

The key idea is that the Palliative Performance Scale is an observer-rated measure used in palliative care, and its scores correlate with how long a patient is likely to survive. A clinician or trained observer rates a patient based on observable functioning across domains such as ambulation, activity level, self-care, intake, and level of consciousness. The total score, typically ranging from 0 to 100, reflects the level of functioning—the higher the score, the better the prognosis, and vice versa. This makes the PPS useful for prognosis and guiding care planning. Karnofsky is another observer-rated scale for performance status, but the PPS is specifically designed for palliative care contexts and ties more directly to survival predictions in this setting. ADL and IADL are measures of daily functioning, not survival itself, so they don’t describe the PPS’s rating and purpose the way the PPS does.
