Information

The Karnofsky Index (or Scale/Status – KPS) is a tool to rate a patient’s ability to perform daily activities, scoring from 0 (dead) to 100 (normal/fully active), indicating functional impairment and prognosis, used in oncology and palliative care to assess fitness for treatment and disease progression. Scores like 90 (normal with minor symptoms), 70 (can care for self but can’t work), 50 (needs significant help/care), and 10 (moribund, rapidly failing) show increasing disability, guiding clinical decisions.
