Key result
The 12-item Duke Activity Status Index provides modest incremental prognostic value for perioperative risk and is best applied as a continuous measure rather than a binary threshold.
Why the study?
Does the 12-item Duke Activity Status Index (DASI) provide incremental prognostic value in perioperative risk prediction?
Does the 12-item Duke Activity Status Index (DASI) provide incremental prognostic value in perioperative risk prediction?
The 12-item DASI offers modest incremental prognostic value for perioperative risk and should be used as a continuous rather than binary measure.
We congratulate Wijeysundera and colleagues1 for this rigorous pooled analysis refining perioperative functional capacity assessment. Their findings show that the 12-item Duke Activity Status Index (DASI) provides modest incremental prognostic value and is best applied as a continuous, context-dependent measure rather than a binary threshold.
