ABSTRACT
Background: Anticoagulation control with warfarin, as assessed by the international normalized ratio (INR), Poor quality of warfarin control by low INR or low time in therapeutic range (TTR) can lead to increased risk of adverse events. The objective of this study was to examine the overall quality of (INR) control and the association of TTR among patients in Gaza Strip.
Method: A prospective study was conducted among patients on warfarin for NVAF who attended the Cardiology Outpatient Clinic of Alshifa Hospital
between June 2021 to October 2022. Patients’ TTR was calculated by using Traditional method
Results: A total of 231 patients were included with mean age 59.15±12.6 years. The mean TTR score was 50.93±16.37%, the total 1155 INR measurements
were calculated. Of the sample patients, 47.6 % were in the good control category (TTR ≥ 60%), and 52.4% were in the poor control category (TTR<60%)
Conclusion: Our study demonstrates more than half of patients have poor anticoagulation control and we urgent need to improve oral anticoagulation care for most patient segments in the Gaza Strip.
