Patients' understanding of anticoagulant therapy.

The paper by Dr Nadar and co-workers (April 2003 JRSM1) pointed out gaps in knowledge about antithrombotic therapy of anticoagulated patients from ethnic minorities in Birmingham. It also indicated that being over 61 years is associated with a low knowledge score. Attempts are made in our monitoring service to inform patients about their warfarin therapy, but only by providing new patients with written information and continuing opportunities to have their questions addressed.
