1. Patient
Definition | Demographics and other administrative information about an individual or animal receiving care or other health-related services.
Control | 0..*
Summary | false
Alternate Names | SubjectOfCare Client Resident
Invariants | Defined on this element dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources (: contained.contained.empty()) dom-3: If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource (: contained.where((('#'+id in (%resource.descendants().reference | %resource.descendants().as(canonical) | %resource.descendants().as(uri) | %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(canonical) = '#').exists()).not()).trace('unmatched', id).empty()) dom-4: If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated (: contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()) dom-5: If a resource is contained in another resource, it SHALL NOT have a security label (: contained.meta.security.empty()) dom-6: A resource should have narrative for robust management (: text.`div`.exists())
2. Patient.implicitRules
Definition | A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.
Control | 0..1
Type | uri
Is Modifier | true
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Comments | 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. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
3. Patient.modifierExtension
Definition | May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it 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 is allowed to 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).
Control | 0..*
Type | Extension
Is Modifier | true
Summary | false
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.
Alternate Names | extensions, user content
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.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists())
4. Patient.identifier
Definition | An identifier for this patient.
Note | This is a business identifier, not a resource identifier (see discussion)
Control | 0..*
Type | Identifier
Summary | true
Requirements | Patients are almost always assigned specific numerical identifiers.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
5. Patient.identifier.use
Definition | The purpose of this identifier.
Control | 0..1
Binding | The codes SHALL be taken from IdentifierUse Identifies the purpose for this identifier, if known .
Type | code
Is Modifier | true
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Requirements | Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.
Comments | Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
6. Patient.identifier.system
Definition | Establishes the namespace for the value - that is, a URL that describes a set values that are unique.
Control | 0..1
Type | uri
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Requirements | There are many sets of identifiers. To perform matching of two identifiers, we need to know what set we're dealing with. The system identifies a particular set of unique identifiers.
Comments | Identifier.system is always case sensitive.
Example | General:http://www.acme.com/identifiers/patient
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
7. Patient.identifier.value
Definition | The portion of the identifier typically relevant to the user and which is unique within the context of the system.
Control | 0..1
Type | string
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Comments | If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the Rendered Value extension. Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe.
Example | General:123456
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
8. Patient.active
Definition | Whether this patient record is in active use. Many systems use this property to mark as non-current patients, such as those that have not been seen for a period of time based on an organization's business rules. It is often used to filter patient lists to exclude inactive patients Deceased patients may also be marked as inactive for the same reasons, but may be active for some time after death.
Control | 0..1
Type | boolean
Is Modifier | true
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Requirements | Need to be able to mark a patient record as not to be used because it was created in error.
Comments | If a record is inactive, and linked to an active record, then future patient/record updates should occur on the other patient.
Meaning if Missing | This resource is generally assumed to be active if no value is provided for the active element
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
9. Patient.name
Definition | A name associated with the individual.
Control | 0..*
Type | HumanName
Summary | true
Requirements | Need to be able to track the patient by multiple names. Examples are your official name and a partner name.
Comments | A patient may have multiple names with different uses or applicable periods. For animals, the name is a "HumanName" in the sense that is assigned and used by humans and has the same patterns.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
10. Patient.name.use
Definition | Identifies the purpose for this name.
Control | 0..1
Binding | The codes SHALL be taken from NameUse The use of a human name.
Type | code
Is Modifier | true
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Requirements | Allows the appropriate name for a particular context of use to be selected from among a set of names.
Comments | Applications can assume that a name is current unless it explicitly says that it is temporary or old.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
11. Patient.name.family
Definition | The part of a name that links to the genealogy. In some cultures (e.g. Eritrea) the family name of a son is the first name of his father.
Control | 0..1
Type | string
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Alternate Names | surname
Comments | Family Name may be decomposed into specific parts using extensions (de, nl, es related cultures).
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
12. Patient.name.given
Definition | Given name.
Control | 0..*
Type | string
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Alternate Names | first name, middle name
Comments | If only initials are recorded, they may be used in place of the full name parts. Initials may be separated into multiple given names but often aren't due to paractical limitations. This element is not called "first name" since given names do not always come first.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
13. Patient.name.prefix
Definition | Part of the name that is acquired as a title due to academic, legal, employment or nobility status, etc. and that appears at the start of the name.
Control | 0..*
Type | string
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
14. Patient.birthDate
Definition | The date of birth for the individual.
Control | 0..1

Summary | true
Requirements | Age of the individual drives many clinical processes.
Comments | At least an estimated year should be provided as a guess if the real DOB is unknown There is a standard extension "patient-birthTime" available that should be used where Time is required (such as in maternity/infant care systems).
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
LOINC Code | 21112-8
15. Patient.deceased[x]
Definition | Indicates if the individual is deceased or not.
Control | 0..1
Type | Choice of: boolean, dateTime
[x] Note | See Choice of Data Types for further information about how to use [x]
Is Modifier | true
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Requirements | The fact that a patient is deceased influences the clinical process. Also, in human communication and relation management it is necessary to know whether the person is alive.
Comments | If there's no value in the instance, it means there is no statement on whether or not the individual is deceased. Most systems will interpret the absence of a value as a sign of the person being alive.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
16. Patient.link
Definition | Link to another patient resource that concerns the same actual patient.

Comments | There is no assumption that linked patient records have mutual links.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
17. Patient.link.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).

This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.
Alternate Names | extensions, user content, modifiers
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.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists())
18. Patient.link.other
Definition | The other patient resource that the link refers to.
Control | 1..1
Type | Reference(Patient|RelatedPerson)

Comments | Referencing a RelatedPerson here removes the need to use a Person record to associate a Patient and RelatedPerson as the same individual.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
19. Patient.link.type
Definition | The type of link between this patient resource and another patient resource.

Type | code
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))

Guidance on how to interpret the contents of this table can be found here.

1. Patient
Definition | Demographics and other administrative information about an individual or animal receiving care or other health-related services.
Control | 0..*
Summary | false
Alternate Names | SubjectOfCare Client Resident
2. Patient.id
Definition | The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.
Control | 0..1
Type | id
Summary | true
Comments | The only time that a resource does not have an id is when it is being submitted to the server using a create operation.
3. Patient.meta
Definition | The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.
Control | 0..1
Type | Meta
Summary | true
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
4. Patient.implicitRules

5. Patient.language
Definition | The base language in which the resource is written.
Control | 0..1
Binding | The codes SHOULD be taken from CommonLanguages A human language
Additional Bindings | Purpose
AllLanguages | Max Binding
Type | code
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | false
Comments | 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).
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
6. Patient.text
Definition | A human-readable narrative that contains a summary of the resource and can 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.
Control | 0..1
Type | Narrative
Summary | false
Alternate Names | narrative, html, xhtml, display
Comments | 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 information is added later.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
7. Patient.contained
Definition | These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope.
Control | 0..*
Type | Resource
Summary | false
Alternate Names | inline resources, anonymous resources, contained resources
Comments | This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels.
8. Patient.extension
Definition | May be used to represent additional information that is not part of the basic definition of the resource. 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.
Control | 0..*

14. Patient.identifier.type
Definition | A coded type for the identifier that can be used to determine which identifier to use for a specific purpose.
Control | 0..1
Binding | The codes SHALL be taken from Identifier Type Codes; other codes may be used where these codes are not suitable A coded type for an identifier that can be used to determine which identifier to use for a specific purpose
Type | CodeableConcept
Summary | true
Requirements | Allows users to make use of identifiers when the identifier system is not known.
Comments | This element deals only with general categories of identifiers. 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. There is not a 1:1 relationship between type and system, since many different systems have the same type.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))

Requirements | Allows for alternative encodings within a code system, and translations to other code systems.
Comments | Codes may be defined very casually in enumerations, or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information. Ordering of codings is undefined and SHALL NOT be used to infer meaning. Generally, at most only one of the coding values will be labeled as UserSelected = true.

Summary | true
Requirements | Need to be unambiguous about the source of the definition of the symbol.
Comments | The URI may be an OID (urn:oid:...) or a UUID (urn:uuid:...). OIDs and UUIDs SHALL be references to the HL7 OID registry. Otherwise, the URI should come from HL7's list of FHIR defined special URIs or it should reference to some definition that establishes the system clearly and unambiguously.

21. Patient.identifier.type.coding.version
Definition | The version of the code system which was used when choosing this code. Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged.
Note | This is a business versionId, not a resource version id (see discussion)
Control | 0..1
Type | string
Primitive Value | This primitive element may be present, or absent, or replaced by an extension

Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Requirements | This has been identified as a clinical safety criterium - that this exact system/code pair was chosen explicitly, rather than inferred by the system based on some rules or language processing.
Comments | Amongst a set of alternatives, a directly chosen code is the most appropriate starting point for new translations. There is some ambiguity about what exactly 'directly chosen' implies, and trading partner agreement may be needed to clarify the use of this element and its consequences more completely.

Control | 0..1
Type | string
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Comments | If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the Rendered Value extension. Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe.

Control | 0..1
Binding | The codes SHALL be taken from AdministrativeGender The gender of a person used for administrative purposes
Type | code
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Requirements | Needed for identification of the individual, in combination with (at least) name and birth date.
Comments | The gender might not match the biological sex as determined by genetics or the individual's preferred identification. Note that for both humans and particularly animals, there are other legitimate possibilities than male and female, though the vast majority of systems and contexts only support male and female. Systems providing decision support or enforcing business rules should ideally do this on the basis of Observations dealing with the specific sex or gender aspect of interest (anatomical, chromosomal, social, etc.) However, because these observations are infrequently recorded, defaulting to the administrative gender is common practice. Where such defaulting occurs, rule enforcement should allow for the variation between administrative and biological, chromosomal and other gender aspects. For example, an alert about a hysterectomy on a male should be handled as a warning or overridable error, not a "hard" error. See the Patient Gender and Sex section for additional information about communicating patient gender and sex.

Multiple GPs may be recorded against the patient for various reasons, such as a student that has his home GP listed along with the GP at university during the school semesters, or a "fly-in/fly-out" worker that has the onsite GP also included with his home GP to remain aware of medical issues. Jurisdictions may decide that they can profile this down to 1 if desired, or 1 per type.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
67. Patient.managingOrganization
Definition | Organization that is the custodian of the patient record.
Control | 0..1
Type | Reference(Organization)
Summary | true
Requirements | Need to know who recognizes this patient record, manages and updates it.
Comments | There is only one managing organization for a specific patient record. Other organizations will have their own Patient record, and may use the Link property to join the records together (or a Person resource which can include confidence ratings for the association).
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
68. Patient.link
Definition | Link to another patient resource that concerns the same actual patient.
Control | 0..*
Type | BackboneElement
Is Modifier | true
Summary | true
Requirements | There are multiple use cases: Duplicate patient records due to the clerical errors associated with the difficulties of identifying humans consistently, and Distribution of patient information across multiple servers.
Comments | There is no assumption that linked patient records have mutual links.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
69. Patient.link.id
Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Control | 0..1
Type | string
XML Representation | In the XML format, this property is represented as an attribute.
Summary | false
70. Patient.link.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.
Control | 0..*
Type | Extension
Summary | false
Alternate Names | extensions, user content
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.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists())
71. Patient.link.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).
Control | 0..*
Type | Extension
Is Modifier | true
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.

72. Patient.link.other
Definition | The other patient resource that the link refers to.
Control | 1..1
Type | Reference(Patient|RelatedPerson)
Summary | true
Comments | Referencing a RelatedPerson here removes the need to use a Person record to associate a Patient and RelatedPerson as the same individual.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
73. Patient.link.type
Definition | The type of link between this patient resource and another patient resource.
Control | 1..1
Binding | The codes SHALL be taken from LinkType The type of link between this patient resource and another patient resource
Type | code
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
