The research showed 25% of people with atrial fibrillation who have a low risk of stroke are prescribed with blood thinners that they do not need. The authors recommend the prescribers to weight the risks and benefits of these medications. Atrial fibrillation patients with low risk of stroke often have higher risk of bleeding compared to the benefits of preventing the stroke. However, the irony of blood thinners is that it is actually under-prescribed in patients who actually need them. How can we regulate overuse and underuse of the medications?
