The purpose of this identifier.

Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.

This is labeled as "Is Modifier" because applications should not mistake a temporary id for a permanent one. Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.

The identification of the code system that defines the meaning of the symbol in the code.

Need to be unambiguous about the source of the definition of the symbol.

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 de-reference to some definition that establish the system clearly and unambiguously.

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.

Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.

A symbol in syntax defined by the system. The symbol may be a predefined code or an expression in a syntax defined by the coding system (e.g. post-coordination).

Need to refer to a particular code in the system.

Note that FHIR strings may not exceed 1MB in size

A representation of the meaning of the code in the system, following the rules of the system.

Need to be able to carry a human-readable meaning of the code for readers that do not know the system.

Note that FHIR strings may not exceed 1MB in size

Indicates that this coding was chosen by a user directly - i.e. off a pick list of available items (codes or displays).

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.

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.

A human language representation of the concept as seen/selected/uttered by the user who entered the data and/or which represents the intended meaning of the user.

The codes from the terminologies do not always capture the correct meaning with all the nuances of the human using them, or sometimes there is no appropriate code at all. In these cases, the text is used to capture the full meaning of the source.

Very often the text is the same as a displayName of one of the codings.

Establishes the namespace for the value - that is, a URL that describes a set values that are unique.

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.

Die Versicherten-ID ist der 10-stellige unveränderliche Teil der 30-stelligen Krankenversichertennummer.

The portion of the identifier typically relevant to the user and which is unique within the context of the system.

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.

Time period during which identifier is/was valid for use.

This is not a duration - that's a measure of time (a separate type), but a duration that occurs at a fixed value of time. A Period specifies a range of time; the context of use will specify whether the entire range applies (e.g. "the patient was an inpatient of the hospital for this time range") or one value from the range applies (e.g. "give to the patient between these two times"). If duration is required, specify the type as Interval|Duration.

Organization that issued/manages the identifier.

The Identifier.assigner may omit the .reference element and only contain a .display element reflecting the name or other textual information about the assigning organization.

Whether this patient record is in active use.

Need to be able to mark a patient record as not to be used because it was created in error.

Default is true. If a record is inactive, and linked to an active record, then future patient/record updates should occur on the other patient

This element is labeled as a modifier because when the patient record is marked as not active it is not expected to be used/referenced without being changed back to active.

Personenname nach deutschem Profil. Dieser enthält bestimmte Extensions, die in Deutschland Verwendung finden.

Need to be able to track the patient by multiple names. Examples are your official name and a partner name.

Names may be changed, or repudiated, or people may have different names in different contexts. Names may be divided into parts of different type that have variable significance depending on context, though the division into parts does not always matter. With personal names, the different parts may or may not be imbued with some implicit meaning; various cultures associate different importance with the name parts and the degree to which systems must care about name parts around the world varies widely.

Telecommunications form for contact point - what communications system is required to make use of the contact.

Note that FHIR strings may not exceed 1MB in size

The actual contact point details, in a form that is meaningful to the designated communication system (i.e. phone number or email address).

Need to support legacy numbers that are not in a tightly controlled format.

Additional text data such as phone extension numbers, or notes about use of the contact are sometimes included in the value.

Identifies the purpose for the contact point.

Need to track the way a person uses this contact, so a user can choose which is appropriate for their purpose.

This is labeled as "Is Modifier" because applications should not mistake a temporary or old contact etc.for a current/permanent one. Applications can assume that a contact is current unless it explicitly says that it is temporary or old.

Specifies a preferred order in which to use a set of contacts. Contacts are ranked with lower values coming before higher values.

Note that rank does not necessarily follow the order in which the contacts are represented in the instance.

Time period when the contact point was/is in use.

This is not a duration - that's a measure of time (a separate type), but a duration that occurs at a fixed value of time. A Period specifies a range of time; the context of use will specify whether the entire range applies (e.g. "the patient was an inpatient of the hospital for this time range") or one value from the range applies (e.g. "give to the patient between these two times"). If duration is required, specify the type as Interval|Duration.

Administrative Gender - the gender that the patient is considered to have for administration and record keeping purposes.

Needed for identification of the individual, in combination with (at least) name and birth date. Gender of individual drives many clinical processes.

The gender may 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 M and F, though the vast majority of systems and contexts only support M and F. Systems providing decision support or enforcing business rules should ideally do this on the basis of Observations dealing with the specific gender aspect of interest (anatomical, chromosonal, 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, chromosonal and other gender aspects. For example, an alert about a hysterectomy on a male should be handled as a warning or overrideable error, not a "hard" error.

The date of birth for the individual.

Age of the individual drives many clinical processes.

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 maternaty/infant care systems).

Adresse nach deutschem Profil. Die in diesem Profil verwendeten Extensions bilden die Struktur der Adresse ab, wie sie im VSDM-Format der elektronischen Versichertenkarte verwendet wird.

May need to keep track of patient addresses for contacting, billing or reporting requirements and also to help with identification.

Note: address is for postal addresses, not physical locations.

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

Most, if not all systems capture it.

Not all terminology uses fit this general pattern. In some cases, models should not use CodeableConcept and use Coding directly and provide their own structure for managing text, codings, translations and the relationship between elements and pre- and post-coordination.

Image of the patient.

Many EHR systems have the capability to capture an image of the patient. Fits with newer social media usage too.

When providing a summary view (for example with Observation.value[x]) Attachment should be represented with a brief display text such as "Attachment".

The nature of the relationship between the patient and the contact person.

Used to determine which contact person is the most relevant to approach, depending on circumstances.

Not all terminology uses fit this general pattern. In some cases, models should not use CodeableConcept and use Coding directly and provide their own structure for managing text, codings, translations and the relationship between elements and pre- and post-coordination.

Personenname nach deutschem Profil. Dieser enthält bestimmte Extensions, die in Deutschland Verwendung finden.

Contact persons need to be identified by name, but it is uncommon to need details about multiple other names for that contact person.

Names may be changed, or repudiated, or people may have different names in different contexts. Names may be divided into parts of different type that have variable significance depending on context, though the division into parts does not always matter. With personal names, the different parts may or may not be imbued with some implicit meaning; various cultures associate different importance with the name parts and the degree to which systems must care about name parts around the world varies widely.

A contact detail for the person, e.g. a telephone number or an email address.

People have (primary) ways to contact them in some way such as phone, email.

Contact may have multiple ways to be contacted with different uses or applicable periods. May need to have options for contacting the person urgently, and also to help with identification.

Adresse nach deutschem Profil. Die in diesem Profil verwendeten Extensions bilden die Struktur der Adresse ab, wie sie im VSDM-Format der elektronischen Versichertenkarte verwendet wird.

Need to keep track where the contact person can be contacted per postal mail or visited.

Note: address is for postal addresses, not physical locations.

Administrative Gender - the gender that the contact person is considered to have for administration and record keeping purposes.

Needed to address the person correctly.

Note that FHIR strings may not exceed 1MB in size

Organization on behalf of which the contact is acting or for which the contact is working.

For guardians or business related contacts, the organization is relevant.

References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.

The period during which this contact person or organization is valid to be contacted relating to this patient.

This is not a duration - that's a measure of time (a separate type), but a duration that occurs at a fixed value of time. A Period specifies a range of time; the context of use will specify whether the entire range applies (e.g. "the patient was an inpatient of the hospital for this time range") or one value from the range applies (e.g. "give to the patient between these two times"). If duration is required, specify the type as Interval|Duration.

The ISO-639-1 alpha 2 code in lower case for the language, optionally followed by a hyphen and the ISO-3166-1 alpha 2 code for the region in upper case; e.g. "en" for English, or "en-US" for American English versus "en-EN" for England English.

Most systems in multilingual countries will want to convey language. Not all systems actually need the regional dialect.

The structure aa-BB with this exact casing is one the most widely used notations for locale. However not all systems actually code this but instead have it as free text. Hence CodeableConcept instead of code as the data type.

Indicates whether or not the patient prefers this language (over other languages he masters up a certain level).

People that master multiple languages up to certain level may prefer one or more, i.e. feel more confident in communicating in a particular language making other languages sort of a fall back method.

This language is specifically identified for communicating healthcare information.

Patient's nominated care provider.

This may be the primary care provider (in a GP context), or it may be a patient nominated care manager in a community/disablity 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.

haupt-behandelnde Organisation nach deutschem Profil. Dieses Profil enthält für Deutschland spezififische Besonderheiten und Extensions.

Need to know who recognizes this patient record, manages and updates it.

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).

The other patient resource that the link refers to.

Referencing a RelatedPerson here removes the need to use a Person record to associate a Patient and RelatedPerson as the same individual.

The type of link between this patient resource and another patient resource.
