Hospitals across the US are accountable for controlled substances federally (to the Drug Enforcement Administration) and to various state agencies, depending on location. A number of facilities and health systems have settled with DEA/Department of Justice and state agencies for falling short of those standards. This session will introduce how basic controlled substance transaction reports can be used to help detect non-compliance in medication handling and consequently prevent diversion. The capabilities of advanced data analytics programs for ongoing surveillance will be discussed. High level operational review of controlled substance processes will be outlined. Pulling reports and operational review together, the session will relay direct experience with maintaining compliance with DEA/DOJ and state Board of Pharmacy settlement agreements.
