This page is part of the FHIR Core Extensions Registry (v5.3.0-ballot-tc1: Release 5.3) based on FHIR (HL7® FHIR® Standard) v5.0.0. This version is a pre-release. The current official version is 5.2.0. For a full list of available versions, see the Directory of published versions

| Standards status: Deprecated | Maturity Level: 3 | Responsible: HL7 International / Orders and Observations | Computable Name: ObsGatewayDevice | |

To be used when the actual gateway used at the time of the observation, and the referenced device is also specified. The gateway device may be acting as a communication/data collector, translator or controller; This extension is useful when there is more than one gateway device, for example, where there are apps on a phone and each are a device, and more than one app is used to pass on the data to a FHIR Server. In that case you need to be able to say from the observation which specific app was used to act as gateway. Note that the Provenance/AuditEvent resources can represent the same information. Use Device Gateway (device-gateway) extension which allows codeableReference (Device) in R6 and requires cross version extension for codeable reference.
Context of Use
This extension is deprecated and should no longer be used
Use Device Gateway (device-gateway) extension which allows codeableReference (Device) in R6 and requires cross version extension for codeable reference.
This extension may be used on the following element(s)
Observation
Using this extension on the Observation resource vs Device.gateway: The actual gateway used must be preserved as the gateway on the Device may change over time, providing a consistent/simpler approach through this extension rather than having to use contained resources or have a history.
