Improving future postoperative atrial fibrillation care: a 30,000-foot viewpoint

Abstract

Aim: In the United States (US), post-operative atrial fibrillation (POAF) is the most common complication following cardiac surgery. In order to understand the opportunities to improve POAF patients’ care, this “30,000 foot” review evaluated the professional society POAF database/registry definitions and guideline recommendations. Methods: All US-based professional society organizations with an interventional cardiac database/registry and/or cardiac care guidelines were identified; from these, the POAF database definitions and guideline recommendations were evaluated using a content analysis approach. Results: The Society of Thoracic Surgeons (STS) POAF definition was the most frequently referenced definition (21% of key references). Only 50% (n = 5/10) US cardiac surgery databases/registries included any POAF definition; compared to STS, the other five definitions required substantially more detailed documentation. Across eight guidelines, three different types of POAF recommendations were found: risk assessment (n = 3); prevention (n = 7); and management (n = 8). As a common feature, the risk assessment strategies tended to focus on advanced age (n = 6). Beta-blockers (n = 5) and amiodarone (n = 6) were common prevention approaches. Uniformly, anti-coagulation was the only management strategy (n = 8) recommended, barring any contraindications. Conclusion: Across ten professional societies, 50% had no POAF definition; of the remaining five, no POAF definitional consistency was found. Across the eight US-based professional society POAF-related guidelines, only anticoagulation was uniformly recommended. Given these “big picture” findings, professional societies are urged to work collaboratively to harmonize these divergent POAF definitions and consolidate their evidence-based guideline recommendations to improve future POAF patients’ quality of care.
