Perioperative medicine & outcomes
Elaboration of a French version of the Duke Activity Status Index questionnaire and performance to predict functional capacity
Authors' conclusion
A FDASI score of 36 represents a reliable threshold the clinicians could routinely use to identify patients with a VO2max < 14 ml.kg-1.min-1.
Study context
- Population
- Consecutive adults undergoing cardiopulmonary exercise test (CPET) for medical or preoperative evaluation, May 2020–March 2021
- Participants
- 122 adults
- Comparison
- FDASI vs Inability to climb two flights of stairs
- Outcome
- Diagnostic performance of FDASI in predicting poor functional capacity (VO2max < 14 ml.kg-1.min-1)
Methodological detailsprospective, consecutive patients, questionnaire translation and validation
- Prospective
- Consecutive patients
- Questionnaire translation and validation
