This means the codes used in route or form may pre-coordinate the method in the route code or the form code. The implementation decision about what coding system to use for route or form code will determine how frequently the method code will be populated e.g. if route or form code pre-coordinate method code, then this attribute will not be populated often; if there is no pre-coordination then method code may be used frequently.', type: CodeableConcept, index: 25} dose: {short: Amount of medication per dose, comments: 'If the administration is not instantaneous (rate is present), this can be specified to convey the total amount administered over period of time of a single administration.', type: Quantity, index: 26} rate: short: Dose quantity per unit of time comments: If the rate changes over time, and you want to capture this in MedicationAdministration, then each change should be captured as a distinct MedicationAdministration, with a specific MedicationAdministration.dosage.rate, and the date time when the rate change occurred.
