"As users become more familiar with the benefits of PDMP report data, requests and the attendant costs to provide them may increase. In Kentucky, Nevada, and Utah, usage has increased substantially, mostly because of the increased number of requests by physicians to check patients' prescription drug histories. In Kentucky, these physician requests increased from 28,307 in 2000, the first full year of operation, to 56,367 in 2001, an increase of nearly 100 percent. Law enforcement requests increased from 4,567 in 2000 to 5,797 in 2001, an increase of 27 percent. Similarly, Nevada's requests from all authorized users have also increased-from 480 in 1997, its first full year, to 6,896 in 2001, an increase of about 1,400 percent. Additionally, as a PDMP matures, the needs it addresses may change, and operating costs may increase as a result."
