Project Information

This project will identify and define the initial set of “key” FHIR resources related to the domain of Patient Administration. These resources will be defined using the available FHIR tooling and in accordance with documented quality guidelines and balloted as part of the initial FHIR specification. Expected FHIR resources to be produced include: Patient, Person, Group, Organization, Encounter, Appointment, Service Delivery Location, Place

In addition, as the committee deems appropriate and time availability permits, it will define a small number of FHIR extensions relevant to domain content and expected to be necessary to support consistent early implementations.

General Considerations

Tier 1: attribution

The single must important question with the administration resources is how to structure the patient/person/role.

  • Should you have patient and something like agent/employee/provider?
  • That's simple, but what do you do about animal? fold it in to patient?
  • maybe you just have patient and animal - but then, do all the clinical resources need to offer either person or animal as context?
  • which clinical resources are human only? are any animal only?
  • what about animals that aren't patients?
  • must you treat patients separately to other kinds of people even if you know they are the same person?
  • what's a patient beyond a person or an animal anyway?
  • how should you manage linking/merging in a restful way? in a safe way?

The current design has the following shape:

  • person - the basic demographics of a human, along with the some intrinsic information about the person themselves
  • animal - a non-human equivalent. Has different demographics and relationships
  • patients - the notion of an individual who has an ongoing record care provision at given institution (scope is flexible)
    • patient points to either person or animal
    • patient records can be linked or unlinked. Records are never "merged" - that's not restful.
  • organization - an abstractly defined entity that provides healthcare
    • LM: We need to loosen this. Not all organizations we care about provide healthcare.
  • agent - a person authorized to perform some role on behalf of an organization (possibly certified by yet another organization)
    • LM: This is often used for Provider, but is more general. Is it too confusing to combine them?

Ongoing open issues:

  • Is it useful to have person separate from patient? should person just be collapsed down into patient and agent? (if so, what happens to animal?)
  • should a person (and animal) have observations? Are some of the attributes (some of which were added in tutorials to demonstrate the methodology) observations
  • which things are in the 80%?
    • For instance, person qualifications are not in the 80%, because you don't keep them about patients. Except that some systems/countries do, and it's about 80% of implementers, not cases. Still, the question is open
  • with regard to patient linking, should there be a preferred? Are only patient records ever merged? How would you cope with this in a legacy system that does true merge at the person level?

Tier 2: process / workflow

The current FHIR resource list anticipates two more resources:

  • admission - the patient is actively moved into care, and out of care.
    • The anticipation is a physical visit (inpatient, emergency, or clinic), but the notion of a physical visit is starting to get outmoded.
    • There are many arguments around what an admission / episode is.
  • InterestOfCare - where a care provider has an ongoing interest in the patients care that continues across multiple episodes
    • typical example, a registered GP in countries where this concept applies
    • an oncologist who will care for a patient across various episodes of surgery, radiotherapy etc

Unfortunately, the differences between these two are somewhat blurry where they meet, and where they intersect with real world work flows. Generally, what else might be required?

  • Future Appointment
  • Transfers
  • record tracking?
