Da der MedicationService möglicherweise an eine ältere Version des KBV-Pakets gebunden ist, würde er die weitergeleiteten E-Rezept-Daten ablehnen. Zukünftig wird der MedicationService in der Lage sein, auf die neuesten KBV-Paketversionen zu aktualisieren, ohne dass eine neue ePA-Version erforderlich ist.\n    Da das E-Rezept *tatsächlich* die Codes gegen die neueste KBV-Paketversion prüft, wird der MedicationService keine \"ungültigen\" Codes erhalten, und die Clients können darauf vertrauen, dass die Daten des MedicationService mit der neuesten KBV-Paketversion übereinstimmen.",

For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. \n\nWhen both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference\n\nApplications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it.\n\nReference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference.  For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation|DiagnosticReport).  One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any).",

Alternatively if the dose was 375 mg, then you may only need to use the Medication resource to indicate this was a tablet. If the example were an IV such as dopamine and you wanted to communicate that 400mg of dopamine was mixed in 500 ml of some IV solution, then this would all be communicated in the Medication resource. If the administration is not intended to be instantaneous (rate is present or timing has a duration), this can be specified to convey the total amount to be administered over the period of time as indicated by the schedule e.g. 500 ml in dose, with timing used to convey that this should be done over 4 hours.",
