The Drug domain system – also known as a Drug Information Systems (DIS) is a core jurisdictional component of the EHRS conceptual system architecture. A DIS records patient prescriptions and medications and provides complete patient drug profiles as well as decision support services for clinicians prescribing and dispensing drugs.
The EHRi Drug Domain services support EHR user requests to retrieve patient clinical data from the Drug domain repository system interface for display.
The following EHRi Drug Domain service operations represent the subset of patient centric queries that would be consumed by an EHR user in the context of an EHRi system. These services are supported by the Canadian Clinical Drug (CeRx) Messaging standard. For more detail information of all drug domain services see Infoway Canadian Clinical Drug (CeRx) Messaging Standard, the first version of the CeRx messaging standard specification and design artefacts can be accessed through Infoway Artefact Repository.
