CoaguChek Measurement terms Prothrombin time (PT) and International Normalised Ratio (INR) are parameters used to measure the activity of oral anticoagulation therapy on the clotting ability of patient blood. Below is a short explanation of the terms most frequently used in the training session. Prothrombin Time (PT) Thromboplastin is added to blood to activate coagulation;...

CoaguChek Limitations - Interferences Important Note – The test interferences below are subject to change therefore always refer to the test strip pack insert for full details and up to date information The blood drop must be a minimum of 8ml in volume. Low sample volume will cause an error message.

The Hughes Syndrome Foundation are a registered UK charity aiming to provide information about Hughes Syndrome (antiphospholipid syndrome: APS). Their website provides information about the charity and all aspects of Hughes Syndrome for patients, doctors and supporters. They have a section on treatment and monitoring of INR by patients themselves with self-testing INR machines, and we would recommend contacting them for any advice on this subject.

Warfarin Interferences Important Note – The interferences below are limited, and subject to change. For a complete list of interferences refer to appropriate documentation for example the British National Formulary The action of oral anticoagulants (coumarin derivatives) can be increased or weakened when other medication is taken simultaneously (e.g.

Training The clinic will be managed by trained staff - designated users. Personnel responsible for the clinic must be aware of professional accountability and undertake the clinic management only if they feel competent to do so. Accredited courses are available. Personnel managing the clinic will also be aware of continued professional development and attend regular updates on anticoagulation management.
Page 57
All patients will remain the responsibility of the referring centre until the patient is seen in the clinic. For patients moving to a new practice, hospital clinics will be informed if patients need to be referred back to the hospital clinic. The same referral form will be used attached to a referral letter with a copy to the patient and new GP if known.

Clinic procedure for novel anticoagulants There are currently NICE technology appraisals available for stroke prevention in atrial fibrillation for dabigatran, rivaroxaban, and apixaban Technology appraisals suggest that they should be made available for patients who require them but that the decision on choice of agent should be undertaken only following an informed discussion with the individual patient.
Page 62
For stroke prevention in atrial fibrillation, patients who would be considered for warfarin should be considered for rivaroxaban Dose 10 mg once daily dose – fixed Starting Rivaroxaban Initial dose should be taken 6 – 10 hours after surgery and for major hip surgery 5 weeks treatment recommended.
