Postoperative delirium: An independent risk factor for poorer quality of life with long-term cognitive and functional decline after cardiac surgery
Authors' conclusion
Postoperative delirium is a risk factor for decreased quality of life in patients 3 years after heart surgery, being associated with greater cognitive and functional deterioration, as well as greater risk of hospital readmission.
Study context
- Population
- Consecutive adults (≥18 years) undergoing cardiac surgery (DELIPRECAS study)
- Participants
- 313 adults
- Exposure
- Postoperative delirium vs no delirium
- Outcome
- Cognitive and functional status (telephone interview) and influence of CAM-ICU-diagnosed postoperative delirium
- Follow-up
- 3 years after cardiac surgery
