MATERIALS &
METHODS: An online survey that included 5 perception and 5 knowledge questions about the testing was conducted on anticoagulation providers in North America. Participants were also asked to rank the three most significant barriers to using it.
RESULTS: The survey response rate was 22%. Over 40% of 448 providers participating in the study were undecided about the testing's potential clinical benefits. On average, providers correctly answered 2 out of 5 knowledge questions. Self confidence in interpreting test results significantly predicted the providers' accuracy of the interpretation. The top three barriers were inadequate literature evidence, testing's impracticality and unproven applicability.
CONCLUSION: Most of the providers did not respond to the survey. Our study suggests inadequate literature evidence influences providers' perception and their use of the testing. In addition, provider education on warfarin pharmacogenetics may be necessary for testing's widespread use. | | Language | eng | | Pub Type(s) | Journal Article
