8.6 Resource Organization - Content

Patient Administration icon Work Group Maturity Level : 5   Trial Use Security Category : Business Compartments : No defined compartments

A formally or informally recognized grouping of people or organizations formed for the purpose of achieving some form of collective action. Includes companies, institutions, corporations, departments, community groups, healthcare practice groups, payer/insurer, etc.

8.6.1 Scope and Usage

This resource may be used in a shared registry of contact and other information for various organizations or it can be used merely as a support for other resources that need to reference organizations, perhaps as a document , message or as a contained resource. If using a registry approach, it's entirely possible for multiple registries to exist, each dealing with different types or levels of organization.

Examples of Organizations include companies, institutions, corporations, departments, community groups, healthcare practice groups, payer/insurer, etc.

8.6.2 Boundaries and Relationships

The Organization resource is used for collections of people that have come together to achieve an objective. The Group resource is used to identify a collection of people (or animals, devices, etc.) that are gathered for the purpose of analysis or acting upon, but are not expected to act themselves.

In the context of service provision, the Organization provides the services, the HealthcareService describes the services provided, and the Location describes the place where the service(s) are offered/available.

The Organization resource often exists as a hierarchy of organization resources, using the part-of property to provide the association of the child to its parent organization.
This organizational hierarchy helps communicate the conceptual structure, whereas the Location resource provides the physical representation of the hierarchy.
The linkage between Organization and Location is from each point in the location hierarchy to the appropriate level in the Organization hierarchy. These links don't all have to be to the top level Organization.
When populating the organization and location hierarchies there is often not a clear distinction between these 2, however to assist in making the decision, Locations are always used for recording where a service occurs, and hence where encounters and observations are associated. The Organization property on these resources might not be the location where the service took place.

OrganizationAffiliation allows you to specify details about organization affiliations that are more complex than simple partOf relationships, such as organizations that are separate legal entities, or have other non-hierarchical relationships. No ownership is implied via OrganizationAffiliation. A single OrganizationAffiliation represents the details of a single relationship between a single pair of Organizations, including the period during which the relationship is active. Current network members can be discovered by searching for OrganizationAffiliations, and historic data can be retained without overhead and still be accessible when searching.

As noted in the Event pattern, a Location represents where a service is performed. An Organization can represent who performed the service.

Set of statuses that apply to qualifications of practitioners and organizations

8.6.4.2 Constraints

UniqueKey Level Location Description Expression
img  org-1 Rule (base) The organization SHALL at least have a name or an identifier, and possibly more than one (identifier.count() + name.count()) > 0
img  org-3 Rule Organization.contact The telecom of an organization can never be of use 'home' telecom.where(use = 'home').empty()
img  org-4 Rule Organization.contact The address of an organization can never be of use 'home' address.where(use = 'home').empty()

8.6.5 Notes:

  • There are two places for contact information: one on Organization itself and zero or more using the ContactEntity construct. The first one is to be used for the generic, public organization point of contact. The ContactEntity is to be used for reaching a person or party that has been designated by the organization to be contacted for a specific purpose or goal.

8.6.6 Example Organization Hierarchy:

An example organization hierarchy should help give some guidance as to one example of how a location hierarchy could look within a fictitious Medical Organization.
(The nesting here would be the "part-of" structure of the Organization resource) 

Burgers University Medical Center
    Eastern Services (prov)
        Emergency Dept
        Oncology Dept
            Nuclear Medicine Research Trials (edu)
        Maternity Ward
        Childrens Ward
        Day Procedures Unit
    Mobile Services (Ambulance)
    Research Center (edu)
        Nuclear Medicine  (edu)
    Burgers University (edu)
        Nuclear Medicine Faculty (edu)
        Undergraduate Medicine (edu)
        ...

Note that physical structures of this hierarchy are not present - these are defined by a Location hierarchy.
