2. Dosage.modifierExtension
Definition | May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
Short | Extensions that cannot be ignored even if unrecognized
Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
Control | 0..*
Type | Extension
Is Modifier | true because Modifier extensions are expected to modify the meaning or interpretation of the element that contains them
Summary | true
Requirements | Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

Requirements | Free text dosage instructions can be used for cases where the instructions are too complex to code. The content of this attribute does not include the name or description of the medication. When coded instructions are present, the free text instructions may still be present for display to humans taking or administering the medication. It is expected that the text instructions will always be populated. If the dosage.timing attribute is also populated, then the dosage.text should reflect the same information as the timing. Additional information about administration or preparation of the medication should be included as text.
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
6. Dosage.timing
Definition | Wann das Medikament verabreicht werden soll. When medication should be administered.
Short | Wann das Medikament verabreicht werden sollWhen medication should be administered
Comments | Um widersprüchliche Anweisungen zu vermeiden, ist entweder Dosage.timing oder Dosage.text zu befüllen. Falls eine strukturierte Dosierung als Text abgebildet werden soll ist dafür die GeneratedDosageInstructionsMeta Extension zu verwenden. This attribute might not always be populated while the Dosage.text is expected to be populated. If both are populated, then the Dosage.text should reflect the content of the Dosage.timing.

Type | Timing(Timing DE)
Is Modifier | false
Must Support | true
Summary | true
Requirements | The timing schedule for giving the medication to the patient. This data type allows many different expressions. For example: "Every 8 hours"; "Three times a day"; "1/2 an hour before breakfast for 10 days from 23-Dec 2011:"; "15 Oct 2013, 17 Oct 2013 and 1 Nov 2013". Sometimes, a rate can imply duration when expressed as total volume / duration (e.g. 500mL/2 hours implies a duration of 2 hours). However, when rate doesn't imply duration (e.g. 250mL/hour), then the timing.repeat.duration is needed to convey the infuse over time period.
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))

10. Dosage.doseAndRate.dose[x]
Definition | Amount of medication per dose.
Short | Amount of medication per dose
Comments | Note that this specifies the quantity of the specified medication, not the quantity for each active ingredient(s). Each ingredient amount can be communicated in the Medication resource. For example, if one wants to communicate that a tablet was 375 mg, where the dose was one tablet, you can use the Medication resource to document that the tablet was comprised of 375 mg of drug XYZ. 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.

Slice Name | doseQuantity
Definition | Menge des Medikaments pro Dosis. Amount of medication per dose.
Short | Menge des Medikaments pro DosisAmount of medication per dose
Comments | Beachten Sie, dass dies die Menge des angegebenen Medikaments angibt, nicht die Menge für die einzelnen Wirkstoffe. Jede Wirkstoffmenge kann in der Medication-Ressource kommuniziert werden. Zum Beispiel, wenn man angeben möchte, dass eine Tablette 375 mg enthält und die Dosis eine Tablette beträgt, kann man die Medication-Ressource verwenden, um zu dokumentieren, dass die Tablette aus 375 mg des Wirkstoffs XYZ besteht. Alternativ, wenn die Dosis 375 mg beträgt, muss man möglicherweise nur angeben, dass es sich um eine Tablette handelt. Bei einer Infusion wie Dopamin, bei der 400 mg Dopamin in 500 ml einer Infusionslösung gemischt werden, würde dies alles in der Medication-Ressource kommuniziert werden. Wenn die Verabreichung nicht als sofortig vorgesehen ist (Rate ist vorhanden oder Timing hat eine Dauer), kann dies angegeben werden, um die Gesamtmenge anzugeben, die über den im Zeitplan angegebenen Zeitraum verabreicht werden soll, z. B. 500 ml in der Dosis, wobei Timing verwendet wird, um anzugeben, dass dies über 4 Stunden erfolgen soll.

30. Dosage.doseAndRate.extension
Definition | May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Short | Additional content defined by implementations
Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

34. Dosage.doseAndRate.dose[x]
Definition | Amount of medication per dose.
Short | Amount of medication per dose
Comments | Note that this specifies the quantity of the specified medication, not the quantity for each active ingredient(s). Each ingredient amount can be communicated in the Medication resource. For example, if one wants to communicate that a tablet was 375 mg, where the dose was one tablet, you can use the Medication resource to document that the tablet was comprised of 375 mg of drug XYZ. 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.

Definition | Menge des Medikaments pro Dosis.
Short | Menge des Medikaments pro Dosis
Comments | Beachten Sie, dass dies die Menge des angegebenen Medikaments angibt, nicht die Menge für die einzelnen Wirkstoffe. Jede Wirkstoffmenge kann in der Medication-Ressource kommuniziert werden. Zum Beispiel, wenn man angeben möchte, dass eine Tablette 375 mg enthält und die Dosis eine Tablette beträgt, kann man die Medication-Ressource verwenden, um zu dokumentieren, dass die Tablette aus 375 mg des Wirkstoffs XYZ besteht. Alternativ, wenn die Dosis 375 mg beträgt, muss man möglicherweise nur angeben, dass es sich um eine Tablette handelt. Bei einer Infusion wie Dopamin, bei der 400 mg Dopamin in 500 ml einer Infusionslösung gemischt werden, würde dies alles in der Medication-Ressource kommuniziert werden. Wenn die Verabreichung nicht als sofortig vorgesehen ist (Rate ist vorhanden oder Timing hat eine Dauer), kann dies angegeben werden, um die Gesamtmenge anzugeben, die über den im Zeitplan angegebenen Zeitraum verabreicht werden soll, z. B. 500 ml in der Dosis, wobei Timing verwendet wird, um anzugeben, dass dies über 4 Stunden erfolgen soll.

38. Dosage.doseAndRate.rate[x]
Definition | Amount of medication per unit of time.
Short | Amount of medication per unit of time
Comments | It is possible to supply both a rate and a doseQuantity to provide full details about how the medication is to be administered and supplied. If the rate is intended to change over time, depending on local rules/regulations, each change should be captured as a new version of the MedicationRequest with an updated rate, or captured with a new MedicationRequest with the new rate. It is possible to specify a rate over time (for example, 100 ml/hour) using either the rateRatio and rateQuantity. The rateQuantity approach requires systems to have the capability to parse UCUM grammer where ml/hour is included rather than a specific ratio where the time is specified as the denominator. Where a rate such as 500ml over 2 hours is specified, the use of rateRatio may be more semantically correct than specifying using a rateQuantity of 250 mg/hour.

Requirements | Identifies the speed with which the medication was or will be introduced into the patient. Typically the rate for an infusion e.g. 100 ml per 1 hour or 100 ml/hr. May also be expressed as a rate per unit of time e.g. 500 ml per 2 hours. Other examples: 200 mcg/min or 200 mcg/1 minute; 1 liter/8 hours. Sometimes, a rate can imply duration when expressed as total volume / duration (e.g. 500mL/2 hours implies a duration of 2 hours). However, when rate doesn't imply duration (e.g. 250mL/hour), then the timing.repeat.duration is needed to convey the infuse over time period.
