KARNOFSKY PERFORMANCE STATUS SCALE DEFINITIONS RATING (%) CRITERIA


The Karnofsky Performance Scale Index allows patients to be classified as to their functional impairment. This can be used to compare effectiveness of different therapies and to assess the prognosis in individual patients. The lower the Karnofsky score, the worse the survival for most serious illnesses.
