Modified from: Oken, M.M. et al. AJCO 1982 (1) and Ma, C. et al. EJC 2010(2). Both ECOG and KPS are clinician-rated instruments that measure functional status. In older adults with chronic diseases a KPS of 60 is associated with a greater risk for hospitalizations, nursing home placement and death (3).
