RESUMO
Background: Atrial fibrillation (AF), a potential trigger for stroke development, is considered a modifiable condition that can halt complications, decrease mortality, and prevent morbidity. The CHA2DS2-VASc and HAS-BLED scores are categorized as risk assessment tools used to estimate the risk of thrombosis development and assess major bleeding among atrial fibrillation patients. Objectives: Our study aims to assess the adherence to post-discharge treatment recommendations according to CHA2DS2-VASc score risk group and evaluate the impact of CHA2DS2-VASc score and HAS-BLED score risk categories on death, length of hospital stay, complications, and hospital readmission among United Arab Emirates (UAE) patients. Methods: This was a multicenter retrospective study conducted from November 2022 to April 2023 in the United Arab Emirates. Medical charts for AF patients were assessed for possible enrolment in the study. Results: A total number of 400 patients were included with a mean age of 55 (±14.5) years. The majority were females (67.8%), and most had high CHA2DS2-VASc and HAS-BLED scores (60% and 57.3%, respectively). Our study showed that adherence to treatment recommendations upon discharge was 71.8%. The bivariate analysis showed that patients with a high CHA2DS2-VASc score had a significantly higher risk of death (p-value of 0.001), hospital readmission (p-value of 0.007), and complications (p-value of 0.044) vs. the low and moderate risk group with a p-value of <0.05. Furthermore, our findings showed that the risk of death (0.001), complications (0.057), and mean hospital stay (0.003) were significantly higher in the high HAS-BLED risk score compared to both the low- and moderate-risk categories. Hospital stay was significantly higher in CHA2DS2-VASc and HAS-BLED high-risk score categories compared to the low-risk score category with a p-value of <0.001. Conclusion: Our study concluded that the adherence to treatment guidelines in atrial fibrillation patients was high and showed that patients received the most effective and patient-centered treatment. In addition, our study concluded that the risk of complications and mortality was higher in high-risk category patients.
