When medication information is stored centrally, where should the information about contra-indications be stored?
When medication is stored in federated systems, locally or interorganisationally, a standardised definition of the data elements and the data formatting of medication information is needed, as information from different sources have to be brought together.
Often, the alerts (interactions, contra-indications and allergies) information is not a part of the prescription system – in that case, the information will have to be distributed separately, or the software that creates the medication list will have to extract this information from other systems (such as an EHR)
