Definition
This section has been translated automatically.

David A. Karnofsky first described a so-called performance status in 1948, which is known as the Karnofsky Index . In this score, each patient is assigned a point value between 0 (dead) and 100 (normal activity) on a linear scale. The measured values are used to roughly scale abilities, activities of daily life and possible dependencies. In 1960 the Eastern Co-operative Oncology Group (ECOG) introduced a further simplified ECOG Performance Status with only 6 points (ECOG/WHO Score).
