The effect of obstructive sleep apnea on readmissions and atrial fibrillation after cardiac surgery.

The study objective was to understand the effect of obstructive sleep apnea on readmission rates and post-operative atrial fibrillation in the cardiac surgical population.

The authors utilized an administrative database consisting of 2007-2014 data from California, Florida, New York, Kentucky, and Maryland from the State Inpatient Databases, Healthcare Cost and Utilization A total of 506,604 patients ≥18 years old who underwent coronary artery bypass grafting surgery (CABG) and/or valve surgery were included in the study. After excluding for death during the index hospitalization and missing data, 396,657 patients remained for 30-day readmission analysis. Results showed that patients with OSA are at increased risk of 30-day readmission and post-operative atrial fibrillation following cardiac surgery compared to those without OSA.
