The Fast Healthcare Interoperability Resources – FHIR Group resource is a standardized data representation format used in healthcare systems to organize and manage groups of related individuals or entities. FHIR is an HL7 (Health Level 7) standard for exchanging healthcare information electronically, and the Group resource is one of the many resource types defined within the FHIR specification.
Introduction
In healthcare settings, it is often necessary to group together individuals or entities for various purposes, such as managing a set of patients belonging to a particular care team, organizing members of a research study, or creating cohorts for population health analysis. The Group resource provides a standardized way to represent and manage such groups.
The Group resource contains information about the group itself, such as its identifier, type, and characteristics, as well as references to the members of the group. Members can be individuals, organizations, or other groups, and the resource allows for flexible grouping structures. For example, a group can have a hierarchical structure where subgroups are nested within parent groups.
The Group resource in FHIR follows a structured format defined by the FHIR specification, which is based on a resource-oriented approach using standard data elements and relationships. It is represented using JSON or XML formats and can be exchanged between different healthcare systems and applications that support FHIR.
By leveraging the FHIR Group resource, healthcare systems, and applications can achieve improved interoperability by ensuring consistent representation and exchange of group-related information. This can facilitate collaborative care, research coordination, and population health management by enabling the seamless sharing and analysis of data across various healthcare entities.
Structure of FHIR Group resource
The structure of the FHIR Group resource in JSON format follows the FHIR specification. Other formats like XML and Turtle exist, but here we will talk about JSON. Here’s an example of how a Group resource might be represented in JSON:
{
"resourceType": "Group",
"id": "example-care-team",
"identifier": [
{
"system": "http://example.com/groups",
"value": "56789"
}
],
"type": "careteam",
"actual": true,
"active": true,
"name": "Example Care Team",
"characteristic": [
{
"code": {
"coding": [
{
"system": "http://example.com/characteristics",
"code": "specialty"
}
]
},
"valueCodeableConcept": {
"coding": [
{
"system": "http://example.com/specialties",
"code": "cardiology",
"display": "Cardiology"
}
]
}
}
],
"member": [
{
"entity": {
"reference": "Practitioner/example-physician"
},
"extension": [
{
"url": "http://example.com/roles",
"valueCodeableConcept": {
"coding": [
{
"system": "http://example.com/roles",
"code": "primary",
"display": "Primary Physician"
}
]
}
}
]
},
{
"entity": {
"reference": "Practitioner/example-nurse"
},
"extension": [
{
"url": "http://example.com/roles",
"valueCodeableConcept": {
"coding": [
{
"system": "http://example.com/roles",
"code": "nurse",
"display": "Nurse"
}
]
}
}
]
}
]
}
The details of this structure example are as follows:
- The group represents a care team, identified by the unique identifier “example-care-team”.
- The group has one identifier, “http://example.com/groups” with a value of “56789”.
- The type of the group is “careteam”, indicating that it represents a care team within a healthcare setting.
- The group is an actual and active care team.
- The group is named “Example Care Team”.
- The characteristic field represents a characteristic of the care team. In this case, it indicates that the care team specializes in cardiology. The code “specialty” is defined in the “http://example.com/characteristics” system, and the valueCodeableConcept specifies that the specialty is cardiology, identified by the code “cardiology” from the “http://example.com/specialties” system, with a display value of “Cardiology”.
- The group has two members: a primary physician and a nurse. Each member is represented by a practitioner reference (e.g., “Practitioner/example-physician” and “Practitioner/example-nurse”).
- Each member also includes an extension to capture their role within the care team. The extension URL “http://example.com/roles” indicates the purpose of the extension. The valueCodeableConcept specifies the role of the member, such as “primary” for the primary physician and “nurse” for the nurse. The display values provide human-readable descriptions of the roles.
This is the structure and displays how an FHIR Group resource can be used to represent a care team in a healthcare context, including their specialty, roles, and member composition.
Commonly used fields in FHIR Group resource.
The FHIR Group resource offers a range of fields that can be used to represent various aspects of a group. Here are some of the commonly used fields in the FHIR Group resource:

Extensions provide flexibility for customizing the Group resource to meet specific needs.
These are some of the commonly used fields in the FHIR Group resource. Depending on the use case and requirements, additional fields or extensions may be utilized to capture more specific details about the group and its characteristics.
A sample use case where FHIR Group resource is utilized
One sample use case where the FHIR Group resource can be utilized is in the representation of a care team within a healthcare setting. Care teams typically consist of various healthcare professionals who collaborate to provide comprehensive care for patients. The FHIR Group resource can help in organizing and managing the members of the care team.
Let’s consider an example scenario:
Use Case: Care Team Management
Description: A hospital wants to efficiently manage the care teams responsible for providing care to their patients. They want to have a standardized representation of care teams using FHIR Group resources. Each care team will consist of a primary physician, a nurse, and a medical assistant.
Solution: Using FHIR Group resource:
Create a FHIR Group resource for each care team, with the following information:
- Assign a unique identifier to each group.
- Set the type of the group as “careteam” to indicate it represents a care team.
- Specify the actual field as
truesince the groups are representing actual care teams. - Set the active field as
trueto indicate the group is currently active. - Provide a name or label for each care team.
- Include the characteristic field to capture relevant information about the care team, such as their specialty or focus area.
- Add member objects for each team member, specifying their role (e.g., primary physician, nurse, medical assistant) and referencing the respective practitioner resources.
Here is the sample Group resource JSON representation.
{
"resourceType": "Group",
"id": "careteam-001",
"type": "careteam",
"actual": true,
"active": true,
"name": "Cardiology Care Team",
"characteristic": [
{
"code": {
"coding": [
{
"system": "http://example.com/characteristics",
"code": "specialty",
"display": "Specialty"
}
]
},
"valueCodeableConcept": {
"coding": [
{
"system": "http://example.com/specialties",
"code": "cardiology",
"display": "Cardiology"
}
]
}
}
],
"member": [
{
"entity": {
"reference": "Practitioner/primary-physician"
}
},
{
"entity": {
"reference": "Practitioner/nurse"
}
},
{
"entity": {
"reference": "Practitioner/medical-assistant"
