Key result
Emergency noncardiothoracic surgery was a strong independent predictor of newly-developed postoperative atrial fibrillation compared to elective surgery (OR 5.149), with an overall incidence of 0.39%.

What is the incidence and what are the predictors of postoperative atrial fibrillation after noncardiothoracic surgery?
Odds Ratio: 5.149 (95% CI 2.294–11.559)
Absolute Event Rate: 1.5% vs 0.2%

Postoperative atrial fibrillation after noncardiothoracic surgery is a rare complication (0.39%) but is associated with older age, emergency operations, longer hospitalizations, and higher in-hospital mortality.
Sohn et al. (2009) conducted a cohort in Postoperative atrial fibrillation (n=7,756). Emergency noncardiothoracic surgery vs. Elective noncardiothoracic surgery was evaluated on Newly-developed postoperative atrial fibrillation (OR 5.149, 95% CI 2.294-11.559, p=<0.001). Emergency noncardiothoracic surgery was a strong independent predictor of newly-developed postoperative atrial fibrillation compared to elective surgery (OR 5.149), with an overall incidence of 0.39%.
