Results: Mean duration of anticoagulant use was 3.05±2.87 years. The most common indication of warfarin was atrial fibrillation. The most frequent bleeding localization was the upper gastrointestinal tract. Thirty-four (38.2%) of the patients had major bleeding, and 55 (61.8%) had minor bleeding. Age, co-administered drugs, amount of erythrocyte suspension transfusion, presence of previous warfarin overdose history, Hb levels at admission, and duration of follow-up in the ED were different between the bleeding types. Conclusion: In this study, we found that the bleeding complications of warfarin were associated with the aged population, presence of previous warfarin overdose history, and concomitant drug use.
