INR home testing devices are available to patients. They are often reimbursable by insurance carriers.  Warfarin management through patient self-testing at home is at least as effective and safe as INR testing through a physician’s office or a warfarin clinic, if patients are well-selected.  The well-done large THINRS trial published in 2010 clearly showed this, and a 2011 systematic review of the medical literature confirmed that Read the rest of this entry »

Coumadin Clinics – Finding One Near You

| Blood thinners (anticoagulants), INR, Therapy, warfarin / coumadin | Comments Off on Coumadin Clinics – Finding One Near You

If you are on warfarin (Coumadin®, Jantoven®) you need to be followed in a structured way to optimize your warfarin therapy and minimize the risk for bleeding and clotting. The “thinness” of your blood needs to be determined on a regular basis with a test called INR (International Normalized Ratio; also referred to as PT, protime, or prothrombin time).  While small physician practices may well deliver good warfarin management care, specialized anticoagulation clinics (also referred to as “Coumadin Clinics”) often have the expertise and resources for optimal warfarin management.  If you are trying to find a clinic near you, you can go to the website of the non-profit organization Anticoagulation Forum. You will find a map of the U.S. with the location of and contact information for a number of good Coumadin Clinics – to link to the map click here. Read the rest of this entry »

Background and Summary

Patients on warfarin can test their own INR (International Normalized Ratio) at home with small, handheld INR monitors, similar to diabetics checking their own blood sugar. A very large, well conducted study published on Oct 21, 2010 in the New England Journal of Medicine (ref 1) shows that patients can safely and effectively monitor their warfarin therapy themselves with INR home monitors. While this does not come as a surprise to many, this is the first very large and well designed trial to show this. Read the rest of this entry »
