Persona con un vínculo legal o familiar con el paciente que necesita identificarse formalmente: el tutor legal, el progenitor de una persona menor de edad o quien firma un consentimiento.

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.

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 its narrative along with other profiles, value sets, etc.

These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, nor can they have their own independent transaction scope. This is allowed to be a Parameters resource if and only if it is referenced by a resource that provides context/meaning.

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.

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 managable, 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.

Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

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.

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.

Documento oficial con que se identifica la persona relacionada: cédula nacional, DIMEX o pasaporte. Es obligatorio, porque identifica, por ejemplo, a quien firma un consentimiento por una persona menor de edad.

RelatedPerson identifiers might not be unique across instances within a system, as a single human individual may be represented as many different RelatedPerson resources with different roles, periods, or relationships.

People are known by a variety of ids. Some institutions maintain several, and most collect identifiers for exchange with other organizations concerning the patient. Examples are national person identifier and local identifier.

The purpose of this identifier.

Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.

Identifies the purpose for this identifier, if known .

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

Tipo de documento: cédula nacional, DIMEX o pasaporte. Es opcional, porque el system ya dice de qué documento se trata; puede llevar además el código equivalente de HL7 v2-0203 (NI, PRC, PPN).

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.

Allows users to make use of identifiers when the identifier system is not known.

Sistema de identificación, que dice qué documento es. El pasaporte lleva al final el código ISO 3166-1 alfa-3 del país emisor (pasaporte/USA).

Identifier.system is always case sensitive.

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.

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 http://hl7.org/fhir/StructureDefinition/rendered-value). 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.

Whether this related person record is in active use.

This element is labeled as a modifier because it may be used to mark that the resource was created in error.

Need to be able to mark a related person record as not to be used, such as if it was created in error.

Paciente con quien la persona tiene un vínculo legal o familiar. Una persona tutora de dos pacientes se registra una vez por cada uno.

Vínculo legal o familiar de la persona con el paciente: cónyuge (SPS), padre (FTH), madre (MTH), tutor legal (GUARD), hijo (CHILD), hermano (SIB) u otro familiar (FAMMEMB). Puede tener varios, por ejemplo madre y tutora legal.

The directionality of the relationship is from the RelatedPerson to the Patient. For example, if the Patient is a child, and the RelatedPerson is the mother, the relationship would be PRN (parent) or MTH (mother).

We need to know the relationship with the patient since it influences the interpretation of the information attributed to this person.

A name associated with the person.

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

The period of time during which this relationship is or was active. If there are no dates defined, then the interval is unknown.

If an individual has a relationship with a patient over multiple, non-adjacent periods, there should be a distinct RelatedPerson instance for each period. For example, if a person is a roommate for a period of time, moves out, and is later a roommate with the same person again, you would have two RelatedPerson instances.

The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.

Within the context of the FHIR RESTful interactions, the resource has an id except for cases like the create and conditional update. Otherwise, the use of the resouce id depends on the given use case.

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.

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.

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 its narrative along with other profiles, value sets, etc.

The base language in which the resource is written.

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).

IETF language tag for a human language

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.

Contained resources do not have a 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.

These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, nor can they have their own independent transaction scope. This is allowed to be a Parameters resource if and only if it is referenced by a resource that provides context/meaning.

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.

A language which may be used to communicate with the related person about the patient's health.

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 RelatedPerson.Communication associations. If the RelatedPerson does not speak the default local language, then the Interpreter Required Standard can be used to explicitly declare that an interpreter is required.

If a related person does not speak the local language, interpreters may be required, so languages spoken and proficiency is an important things to keep track of both for patient and other persons of interest.

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.

IETF language tag for a human language

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

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

This language is specifically identified for communicating healthcare information.

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.
