Key result
Postoperative atrial fibrillation following open-heart surgery is linked to significant economic burden at one year.
Why the study?
Postoperative atrial fibrillation is linked to increased hospitalization costs, but its long-term economic burden remains not well defined.
Does postoperative atrial fibrillation increase healthcare resource utilization and costs in adults undergoing open-heart surgery?

Does postoperative atrial fibrillation increase healthcare resource utilization and costs in adults undergoing open-heart surgery?
p-value: p=<0.001
Postoperative atrial fibrillation after open-heart surgery is associated with significantly increased healthcare resource utilization and costs up to 1 year postdischarge.
May increase focus on POAF prevention in surgical pathways; leaves open whether reducing incidence lowers long-term costs.
BACKGROUND: Postoperative atrial fibrillation (POAF) is one of the most common complications following cardiac surgery. POAF is associated with increased hospitalization costs, but its long-term economic burden is not well defined. OBJECTIVE: To assess 30-day and 1-year incremental healthcare resource utilization (HRU) and costs associated with POAF in the United States (US). METHODS: This retrospective cohort study used claims data from the IBM Watson MarketScan database. A cohort of US adults aged 55--90 years who underwent open-heart surgery between 1 January 2017 and 31 December 2018 was used to compare patients who experienced POAF versus patients who did not (controls). The outcomes of interest were incremental HRU and costs, which were assessed during the index hospitalization and 30-day and 1-year postdischarge time periods. Inverse probability weighting was used to adjust for differences in baseline characteristics. RESULTS: < 0.001), respectively. CONCLUSION: POAF following open-heart surgery poses a significant economic burden up to 1 year postdischarge.

Park et al. (2023) conducted a cohort in Postoperative atrial fibrillation. Postoperative atrial fibrillation vs. No postoperative atrial fibrillation was evaluated on Incremental healthcare resource utilization and costs (p=<0.001). Postoperative atrial fibrillation following open-heart surgery was associated with a significant economic burden up to 1 year postdischarge (P<0.001).
