Resource Profile: Report_EuEncounter - Detailed Descriptions

Draft as of 2025-07-02

Definitions for the Report-EuEncounter resource profile.

Guidance on how to interpret the contents of this table can be foundhere

0. Encounter
Definition

An interaction between a patient and healthcare provider(s) for the purpose of providing healthcare service(s) or assessing the health status of a patient. Encounter is primarily used to record information about the actual activities that occurred, where Appointment is used to record planned activities.

ShortAn interaction during which services are provided to the patient

2. Encounter.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.

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

4. Encounter.contained
Definition

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.

ShortContained, inline 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.

      10. Encounter.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 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. 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).

      ShortExtensions that cannot be ignored
      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.

      Control0..*
      TypeExtension

      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.

              Comments

              While the encounter is always about the patient, the patient might not actually be known in all contexts of use, and there may be a group of patients that could be anonymous (such as in a group therapy for Alcoholics Anonymous - where the recording of the encounter could be used for billing on the number of people/staff and not important to the context of the specific patients) or alternately in veterinary care a herd of sheep receiving treatment (where the animals are not individually tracked).

                Where a specific encounter should be classified as a part of a specific episode(s) of care this field should be used. This association can facilitate grouping of related encounters together for a specific purpose, such as government reporting, issue tracking, association via a common problem. The association is recorded on the encounter as these are typically created after the episode of care and grouped on entry rather than editing the episode of care to append another encounter to it (the episode of care could span years).

                          The participant type indicates how an individual actor participates in an encounter. It includes non-practitioner participants, and for practitioners this is to describe the action type in the context of this encounter (e.g. Admitting Dr, Attending Dr, Translator, Consulting Dr). This is different to the practitioner roles which are functional roles, derived from terms of employment, education, licensing, etc.

Hence CareTeam is not included in Encounter.participant, as the specific individual should be assigned and represented as a Practitioner or other person resource.

                          Similarly, Location can be included in Appointment.participant to assist with planning. However, the patient location is tracked on the Encounter in the Encounter.location property to allow for additional metadata and history to be recorded.

                          The role of the participant can be used to declare what the actor will be doing in the scope of this encounter participation.

                          If the individual is not specified during planning, then it is expected that the individual will be filled in at a later stage prior to the encounter commencing.

                          The participant type indicates how an individual actor participates in an encounter. It includes non-practitioner participants, and for practitioners this is to describe the action type in the context of this encounter (e.g. Admitting Dr, Attending Dr, Translator, Consulting Dr). This is different to the practitioner roles which are functional roles, derived from terms of employment, education, licensing, etc.

                                For planning purposes, Appointments may include a CareTeam participant to indicate that one specific person from the CareTeam will be assigned, but that assignment might not happen until the Encounter begins. Hence CareTeam is not included in Encounter.participant, as the specific individual should be assigned and represented as a Practitioner or other person resource.

                                Similarly, Location can be included in Appointment.participant to assist with planning. However, the patient location is tracked on the Encounter in the Encounter.location property to allow for additional metadata and history to be recorded.

                                The role of the participant can be used to declare what the actor will be doing in the scope of this encounter participation.

                                If the individual is not specified during planning, then it is expected that the individual will be filled in at a later stage prior to the encounter commencing.

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 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).

                                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.

                                The participant type indicates how an individual actor participates in an encounter. It includes non-practitioner participants, and for practitioners this is to describe the action type in the context of this encounter (e.g. Admitting Dr, Attending Dr, Translator, Consulting Dr). This is different to the practitioner roles which are functional roles, derived from terms of employment, education, licensing, etc.

                                            An Encounter may cover more than just the inpatient stay. Contexts such as outpatients, community clinics, and aged care facilities are also included.

                                            The duration recorded in the period of this encounter covers the entire scope of this admission record.

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 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).

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.

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. 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).

The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

It includes non-practitioner participants, and for practitioners this is to describe the action type in the context of this encounter (e.g. Admitting Dr, Attending Dr, Translator, Consulting Dr). This is different to the practitioner roles which are functional roles, derived from terms of employment, education, licensing, etc.

Hence CareTeam is not included in Encounter.participant, as the specific individual should be assigned and represented as a Practitioner or other person resource.

                                                                                                                                        Similarly, Location can be included in Appointment.participant to assist with planning. However, the patient location is tracked on the Encounter in the Encounter.location property to allow for additional metadata and history to be recorded.

                                                                                                                                        The role of the participant can be used to declare what the actor will be doing in the scope of this encounter participation.

                                                                                                                                        If the individual is not specified during planning, then it is expected that the individual will be filled in at a later stage prior to the encounter commencing.

This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

It includes non-practitioner participants, and for practitioners this is to describe the action type in the context of this encounter (e.g. Admitting Dr, Attending Dr, Translator, Consulting Dr). This is different to the practitioner roles which are functional roles, derived from terms of employment, education, licensing, etc.

It includes non-practitioner participants, and for practitioners this is to describe the action type in the context of this encounter (e.g. Admitting Dr, Attending Dr, Translator, Consulting Dr). This is different to the practitioner roles which are functional roles, derived from terms of employment, education, licensing, etc.

Hence CareTeam is not included in Encounter.participant, as the specific individual should be assigned and represented as a Practitioner or other person resource.

                                                                                                                                          Similarly, Location can be included in Appointment.participant to assist with planning. However, the patient location is tracked on the Encounter in the Encounter.location property to allow for additional metadata and history to be recorded.

                                                                                                                                          The role of the participant can be used to declare what the actor will be doing in the scope of this encounter participation.

                                                                                                                                          If the individual is not specified during planning, then it is expected that the individual will be filled in at a later stage prior to the encounter commencing.

Hence CareTeam is not included in Encounter.participant, as the specific individual should be assigned and represented as a Practitioner or other person resource.

                                                                                                                                              Similarly, Location can be included in Appointment.participant to assist with planning. However, the patient location is tracked on the Encounter in the Encounter.location property to allow for additional metadata and history to be recorded.

                                                                                                                                              The role of the participant can be used to declare what the actor will be doing in the scope of this encounter participation.

                                                                                                                                              If the individual is not specified during planning, then it is expected that the individual will be filled in at a later stage prior to the encounter commencing.

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 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 is different to the practitioner roles which are functional roles, derived from terms of employment, education, licensing, etc.

Hence CareTeam is not included in Encounter.participant, as the specific individual should be assigned and represented as a Practitioner or other person resource.

                                                                                                                                                Similarly, Location can be included in Appointment.participant to assist with planning. However, the patient location is tracked on the Encounter in the Encounter.location property to allow for additional metadata and history to be recorded.

                                                                                                                                                The role of the participant can be used to declare what the actor will be doing in the scope of this encounter participation.

                                                                                                                                                If the individual is not specified during planning, then it is expected that the individual will be filled in at a later stage prior to the encounter commencing.

This reason could be patient reported complaint, a clinical indication that was determined in a previous encounter or episode of care, or some planned care such as an immunization recommendation. In the case where you have a primary reason, but are expecting to also address other problems, you can list the primary reason with a use code of 'Chief Complaint', while the other problems being addressed would have a use code of 'Reason for Visit'.

This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

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).

The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.
