Understanding Resources

All FHIR requests are based on resources - modular health data components. For example, a Patient is a resource, as is a Medication. Resources stand on their own, but may have relationships with each other. An Encounter may relate back to a particular Patient and involve several Observations.

Supported Resources

Below is a list of all possible resources supported by the CareEvolution FHIR Interface. The exact list of available resources may vary from site to site and from endpoint to endpoint.

Resource Description
Allergy Intolerance Includes allergies, intolerances, and other adverse reactions to substances.
Audit Event Includes a variety of informational messages about application security, such as failed login attempts and resource access.
Basic Concepts not covered by the base FHIR standard.

Subscription A push-based subscription to the server.
Task A task to be performed.

Each resource has a unique internal ID that permanently identifies it within the HIEBus system. For example, a particular patient my have the ID “d11cf621-ccc0-4492-9e0e-20ee5361fb6e.”

You can use this ID in FHIR operations to access the resource. For example, you could access that patient through the endpoint using [base]/Patient/d11cf621-ccc0-4492-9e0e-20ee5361fb6e.

In addition, resources may have zero or more external identifiers that identify it outside of HIEBus. For example, a patient may have some Medical Record Numbers from different facilities, a state Driver’s License Number, and so on. Unlike the internal ID, external identifiers cannot be used to reference the resource directly. They may be used in searches, as described in requests.
