We compared data from a previous study examining the geographic distribution of prazosin use for PTSD in the VHA between 2004 and 2006 with recent data from 2012 (3). In 2004, 5% of all veterans diagnosed with PTSD in VHA mental health specialty clinics received prazosin, a figure that increased to 17% in 2012. However, in 2004, 38% of patients diagnosed with PTSD within the Puget Sound VA Medical Center, where the treatment was developed, were prescribed prazosin, with monotonic declines to only 2% at medical centers 2,500 miles away or farther, including U.S. East Coast centers. By contrast, in 2012, 33% of patients with PTSD within Puget Sound were prescribed prazosin, a small decline, while the proportion treated with prazosin at medical centers 2,500 miles away or farther had increased 7.6 times to 15%. Prescriptions increased 1.4 times at distances of up to 499 miles, 2.8 times from 500 to 999 miles, and 4.4 times from 1,000 to 2,499 miles.
