St. Peter’s Health's Anticoagulation Clinic provides education and monitoring services to people who are taking the blood thinner, warfarin (Coumadin®).

The clinic is staffed by registered nurses who are specially–trained in managing anticoagulant therapy. Studies have shown that management of warfarin therapy by anticoagulation clinics can reduce the risk of bleeding and reduce the likelihood of forming harmful blood clots.

During each Anticoagulation Clinic visit, the nurse takes a small sample of blood from a finger stick to determine how long it takes the blood to clot. This is called a protime or INR test. In most cases, the protime/INR test result will be available immediately using a portable testing device.

Physicians have given the nurse guidelines which allow the nurse to make adjustments to warfarin doses based on the results of the protime/INR test after a thorough assessment of the patient’s medications, diet, health, and compliance. The information from each Anticoagulation Clinic visit is documented in the patient's electronic medical record.
