Development and validation of a questionnaire to self-assess patient knowledge of direct oral anticoagulants (KODOA-test).

ABSTRACT:

Objective

Few studies have examined associations between patient knowledge of direct oral anticoagulants (DOAC) and clinical outcomes, mostly because of the lack of validated questionnaires for assessing knowledge. The aim of this study was to develop and validate a questionnaire to self-assess knowledge of DOAC.

The Knowledge Of Direct Oral Anticoagulants (KODOA)-test was submitted to patients on DOAC and to pharmacists to assess construct validity. Responsiveness was evaluated after educational counseling. Test-retest reliability was assessed to ensure stability over time, and Cronbach's α was calculated for internal reliability. Index of difficulty and
