It has a narrow therapeutic index and bleeding is the most serious complication of this medication. Thus, frequent International Normalized Ratio (INR) monitoring is required to monitor the risk of bleeding. The control of anticoagulation depends on various factors including diet and drug interactions. Therefore, patients' education must be delivered effectively to improve patients' knowledge and adherence toward warfarin therapy. The objective of this study is to evaluate patients' knowledge and self-reported adherence with the outcome of INR number within the target range. In addition, this study was also intended to assess patients' perception about the warfarin therapy. The questionnaire on patients' knowledge, perception, self-reported adherence, and attitude toward warfarin therapy were distributed randomly to 98 patients attending Outpatient Warfarin Clinic in Tengku Ampuan Rahimah Hospital (HTAR), Klang. Patients enrolled in this study had a mean aged of 50±16 years old, where 46.9% were male and 53.1% were female. This study found that majority of the patients (more than 50%) were well educated on warfarin and generally, their self-reported adherence were reasonably high. However, there was a limited association between patients' knowledge and the number of INR within target range, as only 2 out of 12 questions showed significant difference with the INR number within range. No association was found between patients' self reported adherence with the INR number within range as all of the items asked on their adherence shown p>0.05. This study also found that average patients had a positive perception on warfarin therapy. Most of these patients (83.7%) agreed that counseling session in HT AR helped them in improving their life. This is supported by the number of clinic visits increased the number of INR within therapeutic range. The lacking in association between INR control with knowledge and adherence showed that patients with warfarin therapy should be continuously educated as well as closely monitored. 2008 Thesis https://ir.uitm.edu.my/id/eprint/101085/ https://ir.uitm.edu.my/id/eprint/101085/1/101085.PDF text en public degree Universiti Teknologi MARA (Kampus Puncak Alam) Faculty of Pharmacy Be, Lim Zon
