Figure 1From: Appraisal of the Karnofsky Performance Status and proposal of a simple algorithmic system for its evaluation Proposed algorithm system for the evaluation of the Karnofsky performance status. The initial questions are answered with yes or no answers to discriminate between three statuses: A, B and C (see Table 1). The following questions further distinguish 11 derivative KPS values (100–0%). The items in round brackets () in the follow-up questions lend further suggestive clarification (Schag et al., 1984). The symptom characterization is based on the works of Karnofsky and Burchenal, 1949, and Abernethy et al., 2005 (Table 1).Back to article page
