Doctors and pharmacists treating people with blood thinners can now reduce the rate of inappropriate dosing — as well as blood clots and strokes that can result from it — using an electronic patient management system.
Health Lab
More than two-thirds of those people take a type of blood thinner called a direct oral anticoagulant. These DOACs, such as rivaroxaban (brand name Xarelto) and apixaban (brand name Eliquis), are under- or over-prescribed in up to one in eight patents. These prescribing issues can have life-threatening consequences, and they most often occur after a provider writes the initial prescription, according to a study led by Michigan Medicine.
