Development and Validation of the Knowledge Assessment Tool for New Oral Anticoagulant Use in Patients with Atrial Fibrillation
Keywords:
New oral anticoagulant, Patient knowledge, Knowledge assessment tool developmentAbstract
The purpose of this research was to develop and validate a tool to assess the knowledge of atrial fibrillation (AF) patients on the use of new oral anticoagulants (NOACs). The research was divided into two phases. Phase 1 was the tool development to assess anticoagulation knowledge in AF patients. Phase 2 was the tool validation in the aspects of content validity (in 6 experts), and reliability and item difficulty (in 30 patients). The multiple-choice assessment tool contained twenty-three questions with six dimensions including basic drug information, adverse drug reactions, medication administration, drug-drug interactions, laboratory monitoring, and self-care and lifestyle. Based on the expert evaluation, the tool developed had a scale content validity index of 0.97. A validity test from the patients showed that the tool had a reliability score of 0.95, and the average difficulty of each dimension of the question ranged from 0.22 to 0.96. The tool developed in this study to evaluate knowledge regarding NOAC use in AF patients met the quality criteria for content validity and reliability. Therefore, it can be employed to assess knowledge in AF patients, enabling the development of educational guidance for patient counseling.
