This is data from death certificates listing this as the cause of death.

There were an estimated 30,600,000 prescriptions filled for warfarin in 2004.  This is an estimated increase of 45% from 1998.

So for every 10 million prescriptions filled for warfarin, approximately 1 person died with the primary cause of death being anticoagulation.
