    TypeExtension(Patient Birth Place) (Extension Type: Address)
    8. Patient.identifier
    Definition

    An identifier for this patient.

    Typically, when SSIN is available it is used. Organizations will most likely want to also include a local identifier, using its own system. A type can be added if needed. When an identifier is given, a consumer SHALL NOT ignore it.

      An identifier for this patient according to SSIN (NISS-INSZ.)

      When needed to express a SSIN, it SHALL be done according to these guidelines. Other ways to identify a patient using coding systems remain also possible.

      NoteThis is a business identifier, not a resource identifier (see discussion)

      16. Patient.name
      Definition

      A name associated with the individual.

      It is RECOMMENDED to give at least one familyname and at least one given name when possible and define an 'official' use. When names are given, a consumer SHALL NOT ignore it.

      Must Supporttrue
      LOINC Code
      18. Patient.telecom
      Definition

      A contact detail (e.g. a telephone number or an email address) by which the individual may be contacted.

      It is RECOMMENDED to at least add one phone or email address with clear indication using the .use element whether it is home use, private use,...

      LOINC Code
      20. Patient.gender
      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.

      Special remarks for KMEHR users:

      Please note gender in KMEHR is typically expressed using CD-SEX. The two values that do not map directly to the HL7 dataset are 'undefined' (use 'other') and 'changed' (use the actual gender)

      LOINC Code
      22. Patient.birthDate
      Definition

      The date of birth for the individual.

      It is RECOMMENDED to give the birthdate when available.

      LOINC Code
      24. Patient.birthDate.extension
      SlicingThis element introduces a set of slices on Patient.birthDate.extension. The slices areUnordered and Open, and can be differentiated using the following discriminators:
      • value @ url

        Control0..1
        TypeExtension(Patient Birth Time) (Extension Type: dateTime)
        28. Patient.deceased[x]
        Definition

        Indicates if the individual is deceased or not.

        It is RECOMMENDED to include deceased information when applicable

        [x] NoteSee Choice of Data Types for further information about how to use [x]
        LOINC Code
        30. Patient.address
        Definition

        An address for the individual.

        It is RECOMMENDED to include an address when available. When needed to express the availablity of a Patient at home (e.g. only Wednesdays), another solution will be defined.

        TypeAddress(BeAddress)
        LOINC Code
        32. Patient.maritalStatus
        Definition

        This field contains a patient's most recent marital (civil) status.

        It is RECOMMENDED to include this when available. In a Belgian context, the concept ‘civil state’ , Dutch ‘burgerlijke stand’, French ‘état civil’ is more typically used and this might imply a more neutral concept to the reader. In HL7 semantics however this concept is described as ‘marital status’ and it SHALL be understood as the same concept.

        BindingThe codes SHALL be taken from Civil State
        (required to https://www.ehealth.fgov.be/standards/fhir/core/ValueSet/be-civilstate)
        LOINC Code
        34. Patient.multipleBirth[x]
        Definition

        Indicates whether the patient is part of a multiple (boolean) or indicates the actual birth order (integer). Care SHOULD be given when exchanging Patient instances in a purely administrative flow.

        [x] NoteSee Choice of Data Types for further information about how to use [x]
        LOINC Code
        36. Patient.contact
        Definition

        A contact party (e.g. guardian, partner, friend) for the patient.

        It is RECOMMENDED to include this when available and considered relevant for the patientcare. (e.g. a parent of a young patient)

        Comments

        Contact covers all kinds of contact parties: family members, business contacts, guardians, caregivers. Not applicable to register pedigree and family ties beyond use of having contact.

        Special remarks for KMEHR users:

        A contact person for the patient is not part of the 'patient' element itself in KMEHR. As such, the base resource of this is considered sufficient here. The KMEHR standard defines a contact as a separate element using a value from the KMEHR CD-ITEM table and an appropriate value from CD-CONTACT-PERSON to describe the relation to the patient in the KMEHR message. When needed, using FHIR, the contactperson is included in the FHIR resource Patient. Use cases implementing this contact SHALL be aware not all information of CD-CONTACT-PERSON is covered by the base valueset. The codesystem ‘https://www.ehealth.fgov.be/standards/fhir/core/CodeSystem/CD-CONTACT-PERSON’ SHALL be used to refer to any codes previously used in a KMEHR context that cannot be covered by the base HL7 valueset.

        LOINC Code
        38. Patient.contact.relationship
        BindingUnless not suitable, these codes SHALL be taken from ContactPerson
        (extensible to https://www.ehealth.fgov.be/standards/fhir/core/ValueSet/be-contactperson)
        LOINC Code
        40. Patient.communication
        Definition

        A language which may be used to communicate with the patient about his or her health.

        It is RECOMMENDED to include this when available.

        Comments

        If no language is specified, this implies that the default local language is spoken. If you need to convey proficiency for multiple modes, then you need multiple Patient.Communication associations. For animals, language is not a relevant field, and should be absent from the instance. If the Patient does not speak the default local language, then the Interpreter Required Standard can be used to explicitly declare that an interpreter is required.

        Special remarks for KMEHR users:

        The 'usuallanguage' element in a KMEHR message only refers to the use of W3C language codes. As such, the language codes as proposed in the FHIR standard should not present any interoperability issue. Note the KMEHR element implies it is the language usally used by the patient. As such, when this element from KMEHR would be mapped to a FHIR resource, the communication.preferred Boolean SHOULD be used.

        LOINC Code
        42. Patient.generalPractitioner
        Definition

        Patient's nominated care provider.

        Take note this does not automatically imply any legal form of therapeutic link or consent relationship with this GP. It is RECOMMENDED to include this when available if the flow is in any way medical. Please note this is an element of the Reference datatype. This means when it is available it will contain either a relative or absolute URL where this GP can be found. Alternatively, there is only an internal reference and the GP is included as a ‘contained resource’ (cfr. the HL7 FHIR specifications in what cases this applies).

        Comments

        This may be the primary care provider (in a GP context), or it may be a patient nominated care manager in a community/disability setting, or even organization that will provide people to perform the care provider roles. It is not to be used to record Care Teams, these should be in a CareTeam resource that may be linked to the CarePlan or EpisodeOfCare resources. 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.

        Special remarks for KMEHR users:

        The general practioner is in many KMEHR use cases known by being the author or sender of the message. This is however a functionally different concept from the generalPractioner as it is defined in the FHIR resource. (Consult the published definition on the HL7 webpage) It is also possible in KMEHR to add a general practioner via an item and using the correct value from CD-ITEM. That way is functionally closer to the general practioner referenced here. Note in the FHIR base definition of this element that the scope of this element might be wider then just the general practicioner.

        TypeReference(BeOrganization, BePractitioner, BePractitionerRole)
        LOINC Code
        44. Patient.managingOrganization
        Definition

        Organization that is the custodian of the patient record.

        This SHOULD be included when available.Please note this is an element of the Reference datatype. This means when it is available it will contain either a relative or absolute URL where this Organization can be found. Alternatively, there is only an internal reference and the Organization is included as a ‘contained resource’ (cfr. the HL7 FHIR specifications in what cases this applies).

        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).

        Special remarks for KMEHR users:

        The reference to the managing organization is the organization that is the custodian of the patient record. As there is no explicit ‘author of this record’ – like in a KMEHR message – this element functionally refers to the organization in charge. (Which might also be a GP practice of an individual.)

        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.

        ShortA set of rules under which this content was created
        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.

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.

            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.

            Shortmale | female | other | unknown
            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.

            Special remarks for KMEHR users:

            Please note gender in KMEHR is typically expressed using CD-SEX. The two values that do not map directly to the HL7 dataset are 'undefined' (use 'other') and 'changed' (use the actual gender)

              Note: address is intended to describe postal addresses for administrative purposes, not to describe absolute geographical coordinates. Postal addresses are often used as proxies for physical locations (also see the Location resource).

              Special remarks for KMEHR users:

              Note when .use and .type are used they SHALL use the FHIR defined valuesets as per their required binding level in the FHIR specification. In a KMEHR address, the use was defined by CD-ADDRESS but those values can be found in the FHIR valueset. KMEHR values 'careadress', 'other' and 'vacation' are not directly present in the FHIR address-use table but can be mapped to the value 'temp' in FHIR. In those cases, it is RECOMMENDED to also add a .period. In KMEHR, an address might be expressed using free text or a totally structured approach where the streetname and housenumber are put in separate fields. FHIR prefers a more pragmatic approach where the ‘text’ element is used to print on labels. Also, streetname and number are not separate fields as in KMEHR but in a structural approach are given as one or moren ‘line’ elements. It is however RECOMMENDED to use the Streetname, Housenumber and Postbox extensions to express them seperately. Note the FHIR address also allows to optionally define whether the address is a physical, postal or ‘both’ address using the .type field.

              If no language is specified, this implies that the default local language is spoken. If you need to convey proficiency for multiple modes, then you need multiple Patient.Communication associations. For animals, language is not a relevant field, and should be absent from the instance. If the Patient does not speak the default local language, then the Interpreter Required Standard can be used to explicitly declare that an interpreter is required.

              Special remarks for KMEHR users:

              The 'usuallanguage' element in a KMEHR message only refers to the use of W3C language codes. As such, the language codes as proposed in the FHIR standard should not present any interoperability issue. Note the KMEHR element implies it is the language usally used by the patient. As such, when this element from KMEHR would be mapped to a FHIR resource, the communication.preferred Boolean SHOULD be used.

              Comments

              This may be the primary care provider (in a GP context), or it may be a patient nominated care manager in a community/disability setting, or even organization that will provide people to perform the care provider roles. It is not to be used to record Care Teams, these should be in a CareTeam resource that may be linked to the CarePlan or EpisodeOfCare resources. 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.

              Special remarks for KMEHR users:

              The general practioner is in many KMEHR use cases known by being the author or sender of the message. This is however a functionally different concept from the generalPractioner as it is defined in the FHIR resource. (Consult the published definition on the HL7 webpage) It is also possible in KMEHR to add a general practioner via an item and using the correct value from CD-ITEM. That way is functionally closer to the general practioner referenced here. Note in the FHIR base definition of this element that the scope of this element might be wider then just the general practicioner.

                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.

                    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.

                    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.

                    Please note gender in KMEHR is typically expressed using CD-SEX. The two values that do not map directly to the HL7 dataset are 'undefined' (use 'other') and 'changed' (use the actual gender)

                      Note: address is intended to describe postal addresses for administrative purposes, not to describe absolute geographical coordinates. Postal addresses are often used as proxies for physical locations (also see the Location resource).

                      Special remarks for KMEHR users:

                      Note when .use and .type are used they SHALL use the FHIR defined valuesets as per their required binding level in the FHIR specification. In a KMEHR address, the use was defined by CD-ADDRESS but those values can be found in the FHIR valueset. KMEHR values 'careadress', 'other' and 'vacation' are not directly present in the FHIR address-use table but can be mapped to the value 'temp' in FHIR. In those cases, it is RECOMMENDED to also add a .period. In KMEHR, an address might be expressed using free text or a totally structured approach where the streetname and housenumber are put in separate fields. FHIR prefers a more pragmatic approach where the ‘text’ element is used to print on labels. Also, streetname and number are not separate fields as in KMEHR but in a structural approach are given as one or moren ‘line’ elements. It is however RECOMMENDED to use the Streetname, Housenumber and Postbox extensions to express them seperately. Note the FHIR address also allows to optionally define whether the address is a physical, postal or ‘both’ address using the .type field.

                      It is RECOMMENDED to include this when available. In a Belgian context, the concept ‘civil state’ , Dutch ‘burgerlijke stand’, French ‘état civil’ is more typically used and this might imply a more neutral concept to the reader. In HL7 semantics however this concept is described as ‘marital status’ and it SHALL be understood as the same concept.

                      Special remarks for KMEHR users:

                      A contact person for the patient is not part of the 'patient' element itself in KMEHR. As such, the base resource of this is considered sufficient here. The KMEHR standard defines a contact as a separate element using a value from the KMEHR CD-ITEM table and an appropriate value from CD-CONTACT-PERSON to describe the relation to the patient in the KMEHR message. When needed, using FHIR, the contactperson is included in the FHIR resource Patient. Use cases implementing this contact SHALL be aware not all information of CD-CONTACT-PERSON is covered by the base valueset. The codesystem ‘https://www.ehealth.fgov.be/standards/fhir/core/CodeSystem/CD-CONTACT-PERSON’ SHALL be used to refer to any codes previously used in a KMEHR context that cannot be covered by the base HL7 valueset.

                      Comments

                      If no language is specified, this implies that the default local language is spoken. If you need to convey proficiency for multiple modes, then you need multiple Patient.Communication associations. For animals, language is not a relevant field, and should be absent from the instance. If the Patient does not speak the default local language, then the Interpreter Required Standard can be used to explicitly declare that an interpreter is required.

                      Special remarks for KMEHR users:

                      The 'usuallanguage' element in a KMEHR message only refers to the use of W3C language codes. As such, the language codes as proposed in the FHIR standard should not present any interoperability issue. Note the KMEHR element implies it is the language usally used by the patient. As such, when this element from KMEHR would be mapped to a FHIR resource, the communication.preferred Boolean SHOULD be used.

This means when it is available it will contain either a relative or absolute URL where this GP can be found. Alternatively, there is only an internal reference and the GP is included as a ‘contained resource’ (cfr. the HL7 FHIR specifications in what cases this applies).

                      Comments

                      This may be the primary care provider (in a GP context), or it may be a patient nominated care manager in a community/disability setting, or even organization that will provide people to perform the care provider roles. It is not to be used to record Care Teams, these should be in a CareTeam resource that may be linked to the CarePlan or EpisodeOfCare resources. 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.

                      Special remarks for KMEHR users:

                      The general practioner is in many KMEHR use cases known by being the author or sender of the message. This is however a functionally different concept from the generalPractioner as it is defined in the FHIR resource. (Consult the published definition on the HL7 webpage) It is also possible in KMEHR to add a general practioner via an item and using the correct value from CD-ITEM. That way is functionally closer to the general practioner referenced here. Note in the FHIR base definition of this element that the scope of this element might be wider then just the general practicioner.

                      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).

                      Special remarks for KMEHR users:

                      The reference to the managing organization is the organization that is the custodian of the patient record. As there is no explicit ‘author of this record’ – like in a KMEHR message – this element functionally refers to the organization in charge. (Which might also be a GP practice of an individual.)
