Background: Since the approval of warfarin, a Vitamin K antagonist anticoagulant (VKA), no other oral anticoagulant existed for patients who needed long-term anticoagulation therapy until the recent introduction of non-VKA oral anticoagulants (NOACs). NOACs came to fill in therapeutic gaps associated with VKA. Dedicated anticoagulation clinics has improved the outcome of using VKA. However, with the arrival of NOACs, it is not clear how they will fit into these clinics.Methods: We searched PubMed, Google Scholar, Medline, and African Journals OnLine for articles on anticoagulation management and NOACs. Results: There were very few dedicated anticoagulation management centers in Sub-Saharan Africa, notably in Nigeria, South Africa, Kenya, Uganda, Namibia, Ghana, Botswana, Namibia, and Cameroun and warfarin was the anticoagulant used. NOACs were not used regularly. None of these anticoagulation clinics had incorporated NOACs management into their routine service as was done for VKA. Conclusion: Anticoagulation clinics in Sub-Saharan Africa must include NOACs as part of their area of service in addition to warfarin. The use of NOACs in Africa will leap frog if proper anticoagulation management policy and structure are laid out, the cost of NOACs are reduced, and emphasis is given to retraining of staff.
