Abstract

PURPOSE: The Duke Activity Status Index (DASI), a patient-administered questionnaire, is used to quantify functional capacity in patients undergoing cancer surgery. METHODS: This retrospective cohort study assessed whether the DASI was accurate in predicting peak oxygen consumption (pVO2) that was objectively measured using cardiopulmonary exercise testing (CPET) in 43 consecutive patients scheduled for elective major cancer surgery at a tertiary cancer centre. The primary outcome measured the limits of agreement between DASI-predicted pVO2 and actual measured pVO2. RESULTS: The study population was elderly (median 63 years, interquartile range 18), 58% were male, with the majority having in..
