The data for 2015 includes more than 1.4 billion prescriptions written by nearly 1.4 million doctors, nurses and other providers. This database lists about 447,000 of those providers who wrote 50 or more prescriptions for at least one drug that year. More than three-fourths of these prescriptions went to patients 65 and older; the rest were for disabled patients. Methodology »
