Feasibility and Validity of the Quality of Recovery-15 Questionnaire Following Cardiac Surgery: A Prospective Cohort Study
Authors' conclusion
The QoR-15 questionnaire is feasible, valid, and responsive after cardiac surgery, although its use at 24 hours is limited by reduced independent completion and poor reliability.
Study context
- Population
- Adults undergoing elective cardiac surgery, tertiary high-volume cardiac surgical centre, Vancouver, Canada
- Participants
- 104 adults
- Outcome
- QoR-15 feasibility, scores, responsiveness, validity and reliability
Methodological detailssingle-centre, QoR-15 completed at baseline, 24 and 48 hours after extubation, and at 12 weeks postoperatively (12-week assessment by telephone)
- Single-centre
- QoR-15 completed at baseline, 24 and 48 hours after extubation, and at 12 weeks postoperatively (12-week assessment by telephone)
