What is PDMP and PMIX?
The Prescription Drug Monitoring Program (PDMP) Information Exchange (PMIX) establishes a national interoperability architecture, specifications, and a reusable infrastructure for the secure, reliable, and sustainable interstate exchange of state prescription data. PMIX leverages service-oriented architecture (SOA) principles through the Global Reference Architecture (GRA) to minimize custom development and maximize future agility.
PDMPs maintain statewide electronic databases of prescriptions dispensed for controlled substances (i.e., prescription drugs of abuse that are subject to stricter government regulation). Information collected by PDMPs may be used to support access to and legitimate medical use of controlled substances; identify or prevent drug abuse and diversion, facilitate the identification of prescription drug-addicted individuals and enable intervention and treatment, outline drug use and abuse trends to inform public health initiatives, or educate individuals about prescription drug use, abuse, and diversion as well as about PDMPs.
The PMIX Pilot Program is just a start. Infrastructure for the PMIX Pilot was tested in a successful pilot exchange of live data between the Kentucky All Schedules Prescription Electronic Reporting system and the Ohio Automated Rx Reporting System or RxCheck Hub. Under the PMIX approach, all protected health information was encrypted at the message level so that private data was not visible to any intermediary servers outside state boundaries. The supporting technologies used for the Pilot follow:
The RxCheck Hub is the baseline implementation of the PMIX architecture. The hub was developed, with BJA support, to create an operational data sharing hub to implement the PMIX specifications and to deliver a functional, interstate, data-sharing hub. The RxCheck hub was designed with the involvement of the state PDMP practitioner community, private industry, and the Federal government, and began as the PMIX hub during a prototype development phase with data exchanges between Ohio and Kentucky. The hub was subsequently renamed the RxCheck hub to avoid confusion between the architecture and the hub.
