Prescription Drug Monitoring Programs (PDMPs) are electronic databases designed to track and monitor controlled substance dispensing. These databases are run at the state level, and the main intent of such programs is to screen for suspected drug diversion (i.e., using drugs for illegal purposes such as selling prescribed medications for profit) and abuse. Access to each PDMP is determined by the individual state, but it is typically available to health care providers and pharmacists as a means of reviewing a patient's controlled substance history regardless of source of dispensing (i.e., pharmacy, clinic, hospital) or form of payment (i.e., cash, insurance claim, etc.).
