Patient Unmerge Operation

Experimental

This is an experimental operation within CareConnect that is not yet supported by any Netsmart CareRecord or other solution.

The Patient Unmerge operation is an experimental operation to allow for reversing a previous merge operation based loosely on the draft HL7 FHIR Patient Merge Operation.

Authorization​

This operation will require the application obtain authorization to update a Patient using one of the following SMART clinical scopes.

  • v1: [patient|user|system]/Patient.[write|*]
  • v2: [patient|user|system]/Patient.[u] (future)

Parameters​

UseNameCardinalityTypeDocumentation
INsource-patient1..1ReferenceA direct resource reference to the source patient resource.
INtarget-patient1..1ReferenceA direct resource reference to the target patient resource.
This is the surviving patient resource, the target for the merge.
INpreview0..1booleanThis parameter is not yet supported by any Netsmart CareRecord or solution
If this is set to true then the merge will not be actually performed; an OperationOutcome will be returned in the Parameters response that will indicate that no merge has occurred and may include other diagnostic info if desired, such as the scale of the merge.
e.g. Issue.details.text "Preview only Patient merge - no issues detected"
e.g. Issue.diagnostics "Merge would update: 10 years of content or 120 resources"
The resulting target patient resource will also be returned in the result.
OUToutcome1..1OperationOutcomeThe outcome of the operation. On success this will provide a success statement or warnings related to the change. If the operation was unsuccessful, the OperationOutcome will include the reason for the failure.
