Translation of Karnofsky Performance Status (KPS) for use in inpatient cancer rehabilitation.

Background: Better tools are needed to predict functional decline and oncologic prognosis in inpatient cancer rehabilitation. The Karnofky Performance Status (KPS) is a widely used scale of functional performance in oncology, although the scale differs from current rehabilitation terminology. Use of the KPS in inpatient rehabilitation may support a shared method of communication between cancer rehabilitation providers and the primary oncology teams.
