Systems and methods are provided for identifying and tracking diverters of controlled medications. A system may receive signals indicative of medication dispensing activities by one or more health care providers such as nurses, physicians, or pharmacists. Based on the received signals, the system may determine suspected diverters and provide a graphical interface identifying corresponding factors related to usage, waste, dosage, or other factors associated with the suspected diverters. The graphical interface may provide a list of top diverters and display dispensing transactions performed at a dispensing device.
