About 10% of patients – that are treated by doctors who are advocates of patient self-management (PSM) – practice PSM. Those patients test their INR value themselves mostly on a weekly basis and adjust the dosing of VKAs for themselves. In most cases there is a check-up with their doctors on a quarterly basis. PSM requires a thorough training, which is provided by 36 training centres all over Austria. Most of those training centres are run by doctors and nurses that are part of the Austrian working group for the self-management of oral anticoagulants (ÖASA). After a successful completion of the training the patient can get an INR-self-monitoring-device. Due to the large number of sick funds, reimbursement for the device and test strips can vary from 0-100% reimbursements.
Moreover there also exists a “mix” of the above-mentioned methods: patient-self-testing (PST). In PST patients measure their INR-values themselves – the dosing of the oral anticoagulant is undertaken by a doctor. However it needs to be mentioned that this method is very rare.
With the launch of DOAKs the number of patients prescribed with “traditional” oral anticoagulants reduced. Despite that the number of patients on VKAs remains constant on a high level due to remaining uncertainties concerning DOAKs.
