PLMsimPatientSummaryMedicationStatement
| PLMsimPatientSummaryMedicationStatement (MedicationStatement) | C | MedicationStatement | There are no (further) constraints on this element Element idMedicationStatementShort description Record of medication being taken by a patient DefinitionA record of a medication that is being consumed by a patient. A MedicationStatement may indicate that the patient may be taking the medication now, or has taken the medication in the past or will be taking the medication in the future. The source of this information can be the patient, significant other (such as a family member or spouse), or a clinician. A common scenario where this information is captured is during the history taking process during a patient visit or stay. The medication information may come from sources such as the patient's memory, from a prescription bottle, or from a list of medications the patient, clinician or other party maintains The primary difference between a medication statement and a medication administration is that the medication administration has complete administration information and is based on actual administration information from the person who administered the medication. A medication statement is often, if not always, less specific. There is no required date/time when the medication was administered, in fact we only know that a source has reported the patient is taking this medication, where details such as time, quantity, or rate or even medication product may be incomplete or missing or less precise. As stated earlier, the medication statement information may come from the patient's memory, from a prescription bottle or from a list of medications the patient, clinician or other party maintains. Medication administration is more formal and is not missing detailed information. When interpreting a medicationStatement, the value of the status and NotTaken needed to be considered: MedicationStatement.status + MedicationStatement.wasNotTaken Status=Active + NotTaken=T = Not currently taking Status=Completed + NotTaken=T = Not taken in the past Status=Intended + NotTaken=T = No intention of taking Status=Active + NotTaken=F = Taking, but not as prescribed Status=Active + NotTaken=F = Taking Status=Intended +NotTaken= F = Will be taking (not started) Status=Completed + NotTaken=F = Taken in past Status=In Error + NotTaken=N/A = In Error.

| implicitRules | Σ ?! | 0..1 | uri | There are no (further) constraints on this element Element idMedicationStatement.implicitRulesShort description A set of rules under which this content was created DefinitionA reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. This element is labelled as a modifier because the implicit rules may provide additional knowledge about the resource that modifies it's meaning or interpretation.

Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).

| text | C | 0..1 | Narrative | There are no (further) constraints on this element Element idMedicationStatement.textShort description Text summary of the resource, for human interpretation Alternate namesnarrative, html, xhtml, display DefinitionA human-readable narrative that contains a summary of the resource, and may be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety. Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded in formation is added later.

| reference | Σ C | 0..0 | string | There are no (further) constraints on this element Element idMedicationStatement.informationSource.referenceShort description Literal reference, Relative, internal or absolute URL DefinitionA reference to a location at which the other resource is found.

The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources. Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries.

| identifier | Σ | 1..1 | Identifier | There are no (further) constraints on this element Element idMedicationStatement.informationSource.identifierShort description Logical reference, when literal reference is not known DefinitionAn identifier for the other resource. This is used when there is no way to reference the other resource directly, either because the entity is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference. When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. 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. When 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 Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it.

It SHOULD not be used for codes that correspond 1..1 with the Identifier.system. Some identifiers may fall into multiple categories due to common usage. Where the system is known, a type is unnecessary because the type is always part of the system definition. However systems often need to handle identifiers where the system is not known.

| reasonCode | 0..0 | CodeableConcept | There are no (further) constraints on this element Element idMedicationStatement.reasonCodeShort description Reason for why the medication is being/was taken DefinitionA reason for why the medication is being/was taken. This could be a diagnosis code. If a full condition record exists or additional detail is needed, use reasonForUseReference. A coded concept identifying why the medication is being taken. Condition/Problem/DiagnosisCodes (example) ConditionsThe cardinality or value of this element may be affected by these constraints: ele-1 Constraints

| reasonReference | C | 0..0 | Reference(Condition | Observation) | There are no (further) constraints on this element Element idMedicationStatement.reasonReferenceShort description Condition or observation that supports why the medication is being/was taken DefinitionCondition or observation that supports why the medication is being/was taken. This is a reference to a condition that is the reason why the medication is being/was taken. If only a code exists, use reasonForUseCode. Reference(Condition | Observation) ConditionsThe cardinality or value of this element may be affected by these constraints: ele-1 Constraints

| note | 0..0 | Annotation | There are no (further) constraints on this element Element idMedicationStatement.noteShort description Further information about the statement DefinitionProvides extra information about the medication statement that is not conveyed by the other attributes. For systems that do not have structured annotations, they can simply communicate a single annotation with no author or time. This element may need to be included in narrative because of the potential for modifying information. Annotations SHOULD NOT be used to communicate "modifying" information that could be computable. (This is a SHOULD because enforcing user behavior is nearly impossible). The cardinality or value of this element may be affected by these constraints: ele-1 Constraints

| dosage | S | 0..0 | Dosage | There are no (further) constraints on this element Element idMedicationStatement.dosageShort description Details of how medication is/was taken or should be taken DefinitionIndicates how the medication is/was or should be taken by the patient. The dates included in the dosage on a Medication Statement reflect the dates for a given dose. For example, "from November 1, 2016 to November 3, 2016, take one tablet daily and from November 4, 2016 to November 7, 2016, take two tablets daily." It is expected that this specificity may only be populated where the patient brings in their labeled container or where the Medication Statement is derived from a MedicationRequest. The cardinality or value of this element may be affected by these constraints: ele-1 Constraints
