Karnofsky Performance Scale
Publish date: April 2014
The Karnofsky Performance Scale is an assessment tool intended to assist clinicians and caretakers in gauging a patient's functional status and ability to carry out activities of daily living.
It is important to assess a patient's performance on a regular basis, especially as the effects of HIV progress. Documentation of Karnofsky scores over time may be very useful in following a patient's course of illness, and can help a disabled patient in his/her application for disability benefits. It also is used for some research applications.
