Formula
Subjective classification (0-100) assigned by the clinician.Clinical Pearls
Similar to the ECOG scale, the KPS is used to track disease progression, determine whether a patient can tolerate therapies, and as a criterion for clinical trial enrollment.
Limitations
Can be subjective. KPS and ECOG are often used interchangeably (e.g. KPS 100 = ECOG 0, KPS 80-90 = ECOG 1, KPS 60-70 = ECOG 2).
