title: The future of anticoagulation clinics.
abstract: Anticoagulation therapy is the foundation of treatment for thromboembolic disorders; and coumarin derivatives (warfarin in the United States) are the only orally administered anticoagulant medications currently available. Due to the expense and relative difficulties associated with this route of administration, parenteral drugs are not used routinely for long-term therapy, leaving warfarin as the anticoagulant of choice in the outpatient setting. The management of warfarin is problematic, however, due the nuances of its pharmacodynamic and pharmacokinetic profile and the requirement for frequent monitoring of blood levels. Although management by anticoagulation clinics is considered the gold standard for warfarin therapy, management by an anticoagulation clinic may not be the optimal option from a clinician's view and, in many cases, may not be an option at all. Anticoagulation clinics may impinge on the doctor-patient relationship. Difficulties of communication and reimbursement are not ameliorated by a specialty clinic. Innovations in warfarin management, including patient self-management and computerized dosing programs, are alternatives for improved care that are available with or without input by an anticoagulation service. New oral drugs on the horizon do not require the same intensity of monitoring and do not present the same pharmacodynamic problems associated with warfarin. Warfarin will become obsolete in the foreseeable future. If anticoagulation clinics continue, they must re-define their role as the major part of the workload, warfarin management, disappears. To adapt, clinics must strengthen and enhance their role as coordinators and educators, and less so, managers of anticoagulation therapy.
