HRS Program Modestly Boosts Early Rhythm Control for AF

Why It Matters

Early rhythm control cuts cardiovascular events, yet remains underused; COMPASS shows that structured, system‑wide interventions can close part of that gap, influencing outcomes and future AF care models.

Key Takeaways

• Early rhythm control rose from 29% to 33% after COMPASS
• Ablation use drove most of the increase in early rhythm control
• Referral odds to electrophysiologists grew 43% post‑implementation
• Oral anticoagulation reached only 70‑75%, leaving stroke risk high
• Site variation showed up to 26.2% improvement in early rhythm control

Pulse Analysis

The EAST‑AFNET 4 trial reshaped atrial‑fibrillation management by proving that initiating rhythm control within the first year reduces stroke, heart failure, and mortality. Guideline committees quickly incorporated those findings, urging clinicians to act early, but real‑world adoption lagged. The gap reflects therapeutic inertia, fragmented referral networks, and limited decision‑support tools, especially in community settings where most AF diagnoses occur.

COMPASS tackled these barriers with a multi‑pronged strategy: electronic health‑record alerts, clinician and patient education, and rapid‑access AF clinics. Across three diverse sites—Duke Health, Cedars‑Sinai, and a third system—the program lifted early rhythm‑control rates by 4 percentage points, boosted ablation odds by 68%, and increased referrals to electrophysiologists by 43%. Oral anticoagulation rose modestly to roughly 70‑75%, underscoring persistent gaps in stroke prevention.

The initiative’s modest yet statistically significant gains illustrate that infrastructure, not just guidelines, drives practice change. Scalability is feasible because sites could tailor components to local workflows, suggesting a template for other health networks. However, the uneven site performance and lingering anticoagulation shortfall signal the need for deeper primary‑care engagement and sustained monitoring. Future research must link these process improvements to hard outcomes—stroke rates, hospitalizations, and mortality—to validate COMPASS as a blueprint for nationwide AF care transformation.
