Patients come to us for information and warfarin therapy monitoring. We also provide each patient with their individual warfarin doses, and we print the details of their dosage into their yellow record book.

We monitor patients on warfarin therapy for many different reasons, including: 

  • Atrial fibrillation
  • Mechanical valve replacements
  • Pulmonary embolism
  • Deep venous thrombosis
  • Congenital heart disease
  • Cerebral vascular accident
  • Antiphospholipid syndrome

We give patients their warfarin according to their individual target range, using the computer-assisted dosing (DAWN AC) system. Patient records are kept on our system and each patient keeps their own record in their printed yellow record book.

At your first appointment at the clinic, we will talk to you about your warfarin therapy and give you written information on it. We will also provide you with ongoing information throughout your therapy. 

What we do at the clinic

We have educated some patients to self-test their international normalised ratio (INR) using a CoaguChek XS machine. This is a blood test that checks how long it takes for blood to clot. The patients contact the clinic with their results and we dose them accordingly.

We actively monitor 1,500 patients in the clinic and we have 86 self-testing patients. From 2014 to 2015, we saw 37,275 patients and had 2,251 self-testers contacting the clinic.
