Perioperative medicine & outcomes
Atrial fibrillation versus non-atrial fibrillation in postoperative complications following lumbar surgery: a retrospective case-control study
Authors' conclusion
AF seems to be associated with increased perioperative mortality and complications.
Study context
- Population
- Adults receiving lumbar surgery, Nationwide Inpatient Sample 2016–201910,929 (4.9%) with atrial fibrillation (AF)
- Participants
- 222,557 adults
- Exposure
- AF vs no AF in lumbar surgery
- AFn = 10,929
- Outcome
- Postoperative complications, including in-hospital death
Methodological detailspopulation-based, propensity-score matched, Nationwide Inpatient Sample database
- Population-based
- Propensity-score matched
- Nationwide Inpatient Sample database
Main finding
As reported in the abstract
In-hospital death
In-hospital death risk with AF vs without AF, irrespective of potential confounders (fold)
1.75
Observational data: associations, not effects.
Further findings
Postoperative complications
- AF an independent risk factor for cardiac arrest, postoperative delirium, pneumonia, PE, acute respiratory failure, continuous trauma ventilation, acute renal failure, urinary tract infection, gastrointestinal bleeding, blood transfusion, pyemia, septicemia, death, wound infection, and hemorrhage/hematoma/seroma
