Karnofsky Performance Scale

The Karnofsky Performance Scale (KPS) is a standardized tool used by healthcare professionals to assess a patient's functional status and ability to perform daily activities, particularly in the context of serious medical conditions like cancer. It assigns a score from 0 to 100, reflecting the patient’s overall condition and need for assistance.

A low Karnofsky score, typically under 50, indicates significant disability and frequent medical care needs, often correlating with a reduced life expectancy. However, life expectancy varies depending on the underlying condition, its progression, and available treatments.

In palliative nutritional care, the Karnofsky index helps assess a patient’s functional capacity and nutritional needs. It guides interventions by evaluating how the patient’s physical status impacts their ability to eat, maintain weight, and benefit from supportive care strategies.
