This Prescription Repository Query defines a Retrieve query and HTTP GET transaction that specifies the dispensed medication history information that should be seen by primary care givers to assist in making an informed decision prior to prescribing additional medications to a patient.


PRQ defines services that allow physicians to retrieve their patients’ current dispensed medications. This can be useful for identifying potentially deadly drug to drug interactions and over prescribing for opioids.


  • Prevent doctor shopping
  • Prevent opioid abuse
  • Prevent drug diversion
  • Prevent life threatening drug to drug interactions
  • Provide physicians with vital information to help make an informed decision before prescribing medications.


Prescription drug repositories collect data on prescribing and dispensing of controlled substances. This Prescription Repository Query utilizes Pharmacy and FHIR transactions to query a prescription repository for a patient's dispensed medication history. This dispensed medication history can be utilized by providers, pharmacists, and others to address overuse of opioids, drug diversion, physician shopping, and prevent accidental, life threatening, drug to drug interactions. Integrating this information into an Electronic Health Record (EHR) can help simplify the workflow and inform the physician when prescribing medications to a patient.
