Abstract

Objectives: To evaluate bleeding risk in maintenance hemodialysis patients using the  HAS-BLED  score  and  to  determine  the  association  between  this  score  and bleeding complications. Methods: A Prospective, descriptive, follow-up study was conducted on 153 patients receiving maintenance hemodialysis. Bleeding risk was evaluated at baseline using the HAS-BLED score. Patients were followed for a period of three months to identify clinically significant bleeding events. The relationship between HAS-BLED score and bleeding outcomes was analyzed using appropriate statistical methods. Results: The mean age of the study population was 58.08 ± 14.05 years, with males accounting for 52.9%. The prevalence of systolic blood pressure > 160mmHg was 24.18%, prior stroke was 13.07%, and prior bleeding was 3.26%. According to the HAS-BLED classification, 47.1% of patients were categorized as low risk, 29.4% as moderate risk, and 23.5% as high risk. During follow-up, 4 bleeding events (2.61%) were recorded. Patients with a HAS-BLED score ≥ 3 had a significantly higher risk of bleeding than those with a HAS-BLED score ≤ 2 (OR = 10.545; 95%CI: 1.062 - 104.759; p = 0.041). Conclusion:The HAS-BLED score may serve as a useful tool for stratifying bleeding risk in patients undergoing maintenance hemodialysis. Individuals with higher risk (HAS-BLED ≥ 3) may require closer monitoring and targeted management of modifiable risk factors to reduce bleeding complications.
