abstract

  • Background The impact of different types of extracranial bleeding events on health‐related quality of life and health‐state utility among patients with atrial fibrillation is not well understood. Methods and Results The ENGAGE AF ‐ TIMI 48 (Effective Anticoagulation With Factor Xa Next Generation in Atrial Fibrillation–Thrombolysis in Myocardial Infarction 48) Trial compared edoxaban with warfarin with respect to the prevention of stroke or systemic embolism in atrial fibrillation. Data from the EuroQol‐5D ( EQ ‐5D‐3L) questionnaire, prospectively collected at 3‐month intervals for up to 48 months, were used to estimate the impact of different categories of bleeding events on health‐state utility over 12 months following the event. Longitudinal mixed‐effect models revealed that major gastrointestinal bleeds and major nongastrointestinal bleeds were associated with significant immediate decreases in utility scores (−0.029 [−0.044 to −0.014; P <0.001] and −0.029 [−0.046 to −0.012; P =0.001], respectively). These effects decreased in magnitude over time, and were no longer significant for major nongastrointestinal bleeds at 9 months, but remained borderline significant for major gastrointestinal bleeds at 12 months. Clinically relevant nonmajor and minor bleeds were associated with smaller but measurable immediate impacts on utility (−0.010 [−0.016 to −0.005] and −0.016 [−0.024 to −0.008]; P <0.001 for both), which remained relatively constant and statistically significant over the 12 months following the bleeding event. Conclusions All categories of bleeding events were associated with negative impacts on health‐state utility in patients with atrial fibrillation. Major bleeds were associated with relatively large immediate decreases in utility scores that gradually diminished over 12 months; clinically relevant nonmajor and minor bleeds were associated with smaller immediate decreases in utility that persisted over 12 months.
