FamilyMemberHistory on the FHIR specification website.

Significant health conditions for a person related to the patient relevant in the context of care for the patient.

The body should be a list of valid JSON patches for FamilyMemberHistory. For example, to update a Slot status to busy, this would be the body:

[
  {
    op: 'replace',
    path: '/status',
    value: 'busy',
  },
],
