Insights
Patients with nonvalvular atrial fibrillation found dabigatran more convenient and satisfying than vitamin K antagonists over six months. This direct oral anticoagulant improved patient perception, with low discontinuation rates due to side effects.
Area of Science:
- Cardiology
- Pharmacology
- Patient-Reported Outcomes
Background:
- Nonvalvular atrial fibrillation (NVAF) necessitates anticoagulation to prevent stroke.
- Vitamin K antagonists (VKAs) are traditional anticoagulants with limitations.
- Dabigatran, a direct oral anticoagulant (DOAC), offers an alternative treatment option.
Purpose of the Study:
- To evaluate patient perceptions of dabigatran therapy compared to prior VKA treatment.
- To assess changes in convenience and satisfaction scores over a 6-month period.
- To analyze factors influencing patient satisfaction and convenience with dabigatran.
Main Methods:
- Prospective, noninterventional, multicenter study design.
- Inclusion of 659 patients with NVAF previously treated with VKAs.
- Assessment of patient perceptions using the PACT-Q2 questionnaire.
Main Results:
- Significant increases in convenience and satisfaction scores were observed over 6 months.
- Higher convenience scores noted in males and patients with low-moderate thromboembolic risk.
- Higher satisfaction scores reported by female patients; only 8.0% discontinued dabigatran.
Conclusions:
- Dabigatran demonstrated superior convenience and satisfaction compared to VKAs in NVAF patients.
- The study highlights improved patient-reported outcomes with dabigatran therapy.
- Low discontinuation rates suggest good tolerability and adherence to dabigatran.
Abstract:
Aim: To analyze the perception of anticoagulation with dabigatran in patients with nonvalvular atrial fibrillation previously treated with vitamin K antagonists over a 6-month period. Materials & methods: This is a prospective, noninterventional, noncontrolled, multicenter study. To assess patients' perceptions, PACT-Q2 questionnaire was completed. Results: Six hundred and fifty nine patients (73.1 ± 9.4 years, CHA2DS2-VASc 3.6 ± 1.6) were included. At baseline, the convenience and satisfaction scores were 60.9 ± 24.9 and 49.9 ± 17.7, respectively. The scores significantly increased along the study. Convenience score was higher in males and in patients with low-moderate thromboembolic risk. Satisfaction score was higher in females. Only 8.0% of patients discontinued dabigatran (3.7% due to side effects). Conclusion: Convenience and satisfaction scores for nonvalvular atrial fibrillation patients treated with dabigatran at 6 months were significantly better than with previous vitamin K antagonists.
