Perioperative medicine & outcomes
The clinical effectiveness of preoperative screening and post-screening interventions for obstructive sleep apnea: A systematic review and meta-analysis
Authors' conclusion
Our findings confirm HR-OSA as a risk factor for postoperative adverse events.
Study context
- Population
- Surgical patients screened preoperatively for obstructive sleep apnea (OSA) with validated tools
- Participants
- 324,935 patients · 54 studies
- Comparison
- High risk of OSA (HR-OSA) vs low risk of OSA (LR-OSA); post-screening interventions vs no intervention in HR-OSA
- Outcome
- Postoperative adverse respiratory and cardiac events, delirium, length of stay (LOS), ICU admissions, 30-day readmissions, and mortality
