Advisory: SDA3 -> FHIR Transformation Failure

Alert ID	Product & Versions Affected	Risk Category & Score	Explicit Requirements
HSHC-5268	HealthShare® Health Connect and InterSystems IRIS® for Health versions 2025.1.1	Functional: Medium Risk	Occurs when performing SDA3 -> FHIR transformations involving the Encounter resource.

In HealthShare Health Connect and Intersystems IRIS for Health 2025.1.1, SDA3 → FHIR transformations for the Encounter resource may fail.

The DTL HS.FHIR.DTL.SDA3.vR4.Encounter.Encounter references the property AdmitReasonReference in HS.SDA3.Encounter. This property is missing in HealthShare Health Connect and InterSystems IRIS for Health 2025.1.1. As a result, transformations fail with an error such as:

<Ens>ErrException: <PROPERTY DOES NOT EXIST>
Transform+171^HS.FHIR.DTL.SDA3.vR4.Encounter.Encounter.1*AdmitReasonReference,HS.SDA3.Encounter


Effects of this issue are:

• SDA3 ->FHIR transformations involving Encounter objects fail.
• HL7 -> SDA3 -> FHIR interoperability pipelines relying on this mapping are blocked until patched.

There is no impact to system availability or database integrity.
