Duke Activity Status Index (DASI)
Functional capacity and estimated METs from 12 activities.
Inputs
Can you take care of yourself (eat, dress, bathe, toilet)?
Can you walk indoors, such as around your house?
Can you walk a block or two on level ground?
Can you climb a flight of stairs or walk up a hill?

Can you have sexual relations?
Can you moderate recreation (golf, bowling, dancing, doubles tennis)?

Worked calculation
Your values are highlighted.
- VO₂peak
- METs
When to use
- Preoperative evaluation for noncardiac surgery.
Pearls and pitfalls
- DASI above 34 (about 4 METs or more) was associated with fewer cardiac complications in the METS study.
- ACC/AHA: 4 METs or more and no symptoms generally allows surgery without further testing.
Why use
Better than subjective impression of exercise tolerance.
