Performance measures (PMs) are used to accelerate translation of scientific evidence into clinical practice. However, it remains unknown how they are applied in the real world and whether the compliance to these metrics will lead to improved patient's outcome in atrial fibrillation (AF). Within the Japanese multicenter AF registry (n = 1,874), adherence of the AF PMs (based on 2016 American Heart Association/American College of Cardiology criteria) and its association with quality of life scaling and clinical outcomes was evaluated. The patient was deemed "adherent" when all applicable components of the PMs for outpatient settings (CHA2DS2-VASc risk score documentation [PM-4], anticoagulation prescribed [PM-5], and monthly international normalized ratio (INR) for warfarin treatment [PM-6]) were satisfied. The Atrial Fibrillation Effect on Quality of Life (AFEQT) questionnaire was assessed at baseline and 1 year. About a half of patients (46.1%) were adherent to the AF PMs. PMs were more frequently achieved in patients managed with rhythm control compared with rate control. The achievement rate for each component was 53.9% for PM-4, 85.6% for PM-5, and 90.3% for PM-6, respectively. Although AFEQT global scores at baseline were similar (median 79.2 [interquartile ranges 66.7 to 88.5] vs 77.1 [64.8 to 88.0], p = 0.227), AFEQT global scores at 1-year follow-up were significantly greater in adherence group than those in nonadherence group (89.2 [78.5 to 96.6] vs 86.7 [76.7 to 95.0], p = 0.021). This tendency was consistent regardless of therapeutic strategies. There remains an important opportunity to improve the quality of care in patients with AF. Adherence to the AF PMs might lead to the improvement of patient's quality of life.
