    To examine patients’ perspectives regarding long-term vitamin K antagonist (VKA) therapy and the potential transition to new oral anticoagulants (NOACs) such as dabigatran and rivaroxaban, and to determine if factors such as residential location affect these opinions. Patients on VKA therapy for at least 12 weeks completed a questionnaire specifically designed for the study. They were recruited while attending point-of-care international normalized ratio (INR) testing at six South Australian general practice clinics during the period July–September 2013. Opinions of current VKA therapy, level of awareness of NOACs, and ratings of potential benefits and deterrents of transition to NOACs were sought. Data from 290 participants were available for analysis (response rate 95.4%). The majority of the sample (79.5%, 229/288) were either satisfied or very satisfied with current VKA therapy. The mean score for the potential benefits of transition to NOACs was 7.6 (±4.2) out of a possible 20, which was significantly lower than the mean score 10.9 (±4.5) for the perceived deterrents to transition (p < 0.001). Rural patients (82.0%, 82/100) were significantly more likely (p = 0.001) to have not heard of NOACs than metropolitan patients (50.3%, 95/189) and also perceived significant less benefits in a transition to NOACs (p = 0.001). When considering potential transition from VKAs to NOACs it is important for prescribers to consider that some patients, in particular those from a rural location, may not perceive a significant benefit in transitioning or may have particular concerns in this area.
