Anti Coagulant Services

The Leeds Anticoagulant Service is responsible for the control and monitoring of patients on anticoagulants. This includes warfarin (and other vitamin K antagonist drugs), low molecular weight heparins (LMWH) and direct oral anticoagulants (DOACs) such as rivaroxaban, apixaban, edoxaban and dabigatran. Patients may be on anticoagulants for prevention of strokes in AF (Atrial Fibrillation), or to prevent occurrence of venous thrombotic events.

The service was originally set up and managed by the Pathology department, but now comprises a multidisciplinary team of nurses, clinical pharmacists and pharmacy technicians, biomedical scientists, clinical support workers, phlebotomists and clerical & administration staff supported by a consultant haematologist and speciality haematology doctor. Each team member brings knowledge and skills from their discipline to deliver a high quality service.

The service currently provides monitoring for over 6500 patients on warfarin or other vitamin K antagonist drugs from a variety of hospital and community based locations. On average the service delivers over 5000 appointments a month, the majority of which use blood test results obtained by hand-held point of care devices and modern dosing assistance software.
