I wanted to self dose because I live about twenty mile from the nearest medical facilities. My PCP probably would have been the last to agree to this but my Cardiologist happens to be my son-in-law and he actively supported the idea. Now I don't have to waste two hours in the car, sit in a germ filled waiting room, and I can take the unit with me when I travel. I also self dose and email the INR and dosing changes in to my cardios Coumadin clinic. Self testers/self dosers are still pretty rare, but I don't know why they should be. Once you have experienced the freedom of doing this, you would never go back. I have a brother in law who still gets full blood draws and can't conceive of doing it himself - whatever. Several things need to change before the medical industry imbraces the idea fully: We have to convince the physicians that it is safe and doesn't threaten them (Some feel they are still responsible for the patient's INR and could be sued- maybe they could?) and secondly, the coumadin clinics would need to change their treatment model to allow for phone-in or email-in INR results, and to remind a patient if they haven't heard from them within a given guideline. The insurance industry would also need to agree to payment for the less active role of the coumadin clinic. Lastly, a more substantial education program would need to be available for the self doser so that they and their physician are comfortable that the skill is there. Hope this helps
