Coumadin Clinic (Anticoagulation Management Service or AMS)

Emory’s Coumadin Clinic, also called the Anticoagulation Management Service (AMS), serves all of the anticoagulated patients of Emory Healthcare. Anticoagulants are often called "blood thinners" because these types of medicines work on the clotting system in the body to help prevent the formation of blood clots. Anticoagulants are prescribed for a variety of conditions, and regular monitoring and adjustments are necessary to make sure each condition is appropriately treated.

The clinic is staffed by ten nurse practitioners, two nurses, and four clerical staff members at three locations. Each site also has a dedicated physician who serves as medical director and who reviews patient charts on a daily basis. Patients must be referred to the Coumadin Clinic/AMS by the Emory Healthcare provider who is prescribing the blood thinners or who is serving as the patient's primary care provider. The clinic works in close contact with any referring healthcare providers. This helps to ensure that patients on these medicines are closely followed in an effort to reduce the risk of complications, such as bleeding, from the medicine.

The majority of patients who are referred for care by Emory's Coumadin Clinic/AMS are anticoagulated with Coumadin (warfarin sodium). This blood thinner requires regular blood testing of the International Normalized Ratio (INR) level. This blood test tells the healthcare provider how much or how little the medicine is working to prevent blood clots. The Coumadin Clinic / AMS provides INR testing using state-of-the-art instruments. The INR test usually requires only a simple finger stick blood draw, and the result is available within seconds. As soon as the results are available, the Coumadin Clinic/AMS health care provider has a face-to-face visit with the patient where the results are discussed. A bleeding risk assessment is conducted, education is provided, and adjustment of medicine dosing, if necessary, is determined. Prior to leaving the office, the patient is provided with written instructions about what was discussed during the visit, and when to return for future testing.

The referring healthcare provider is contacted immediately about any potential problems the Coumadin Clinic/AMS health care provider discovers at the time of the visit. The INR results are sent to the referring healthcare provider at the end of each visit.

The Coumadin Clinic/AMS also manages patients who are anticoagulated with other medications, including Low Molecular Weight Heparin.
