A dosing service or clinic for patients taking warfarin can be a place where physicians, nurses, or pharmacists can provide consistent management of therapy and response. Many patients on warfarin see more than one physician, and it may not always be clear who is managing the warfarin therapy. Plus, physicians have varying amounts of experience managing patients on warfarin. Patients and physicians can both benefit from a dosing service or clinic, which helps to ensure consistency of care, timely evaluation of laboratory results, and prompt response to patients’ anticoagulant needs. The service or clinic can significantly reduce the risk of adverse drug events and improve satisfaction for patients and clinicians.
