Pharmacist management of anticoagulant therapy in ambulant patients.

The development, operation, patient management protocol and teaching activities of a pharmacist-managed anticoagulant clinic for ambulatory patients are described. Pharmaceutical services provided in the ambulatory clinic include (1) contribution to the problem-oriented medical record; (2) patient education; (3) therapeutic response monitoring; (4) drug information; (5) drug distribution; and (6) inservice education. A pharmacist completes a medication history on initial visit; assesses and adjusts anticoagulant therapy based on physical examination, detection of adverse drug reactions and laboratory test results; schedules return clinic visits; provides patient education; and records, in the patient's medical record, the assessment and results of treatment. Treatment adjustments made by the pharmacist are based on an oral anticoagulant protocol and reviewed by the clinic cardiologist. The clinic serves as a teaching site for undergraduate pharmacy students, Doctor of Pharmacy students and hospital pharmacy residents. The anticoagulant clinic gives the pharmacist a unique opportunity to provide comprehensive pharmaceutical services, to establish effective, long-term professional relationships with ambulant patients and their families, and to foster interdisciplinary health team activities.
