Duke Activity Status Index (DASI)

Patient-reported estimate of functional capacity, VO2 max and METs

About

The Duke Activity Status Index is a patient-reported estimate of functional capacity, maximal oxygen consumption (VO2 max) and maximum metabolic equivalent of tasks (METs). The DASI questionnaire produces a score between 0 and 58.2 points, which is linearly correlated with a patient’s VO2 max and METs, as measured from cardiopulmonary exercise testing (CPET).

Questionnaire

  • Take care of self (e.g. eating, dressing, bathing, using the toilet)?
    • Yes (+ 2.75)
    • No (+ 0.0)
  • Walk indoors (such as around your house)?
    • Yes (+ 1.75)
    • No (+ 0.0)
  • Walk 1-2 blocks on level ground?
    • Yes (+ 2.75)
    • No (+ 0.0)
  • Climb a flight of stairs or walk up a hill?
    • Yes (+ 5.50)
    • No (+ 0.0)
  • Run a short distance?
    • Yes (+ 8.00)
    • No (+ 0.0)
  • Do light work around the house (e.g. dusting, washing dishes)?
    • Yes (+ 2.70)
    • No (+ 0.0)
  • Do moderate work around the house (e.g. vacuuming, sweeping floors carrying in groceries)?
    • Yes (+ 3.50)
    • No (+ 0.0)
  • Do heavy work around the house (e.g. scrubbing floors, lifting or moving heavy furniture)?
    • Yes (+ 8.00)
    • No (+ 0.0)
  • Do yard work (e.g. raking leaves, weeding, pushing a power mower)?
    • Yes (+ 4.50)
    • No (+ 0.0)
  • Have sexual relations?
    • Yes (+ 5.25)
    • No (+ 0.0)
  • Participate in moderate recreational activities (e.g. golf, bowling, dancing, double tennis, throwing a baseball or football)?
    • Yes (+ 6.00)
    • No (+ 0.0)
  • Participate in strenuous sports (e.g. swimming, singles tennis, football, basketball, skiing)?
    • Yes (+ 7.50)
    • No (+ 0.0)

Result:

  • DASI = Sum of questionnaire responses
  • VO2 max (in mL/kg/min) = 0.43 x DASI + 9.6
  • METs (in metabolic equivalents) = VO2 max / 3.5
