Why this companion guide

Purpose: To provide a guide for translating from different sources including providing a provenance resource to describe the actions taken to translate to the observation resource.

Most likely sources:


Three target audiences:


We are working with US Core resources. Each profile has a minimum set of required fields. Beyond those fields additional data SHALL be provided if it is available. When dealing with different data sources there will likely be different levels of data granularity.

In the context of this guide this document provides a mapping of different data sources to the observation profile. The objective of this guide is to enable Payers to map their data from different sources consistently.

A provenance resource SHALL be constructed for each record to identify the originator of the data (the provider/organization etc.), the transmission format (C-CDA, ADT, 837 etc.) which indicates the type of translation performed.


Approach

We want to complement rather than duplicate work.


Resource Mappings

Mapping Assumptions

HL7v2-to-FHIR

The HL7v2-to-FHIR sub-team is currently working through these mapping alignment issues and noting them within the documentation of each HL7v2 segment mapping


Mapping Artifacts

The attached Spreadsheet provides a mapping from Health Plan data sources to the FHIR US Core (R4) Profile:

Latest: Observation-FHIR_R4 v1.4.xlsx

Examples

Example1: HbA1c

The following FHIR instances are in context with the HL7v2 ORU^R01 example for an HbA1c.  They contain references to each other adn should be considered as a group.

What is the scope/grounding on identifying intermediaries?


Health Plan Data Exchange (Template)

Document how the health plan will support the use case scenario outlined above....

Health Plan Data Sources

Identify the potential data sources the Health Plan would use to support the data exchange...

PDex/HRex FHIR Resources 

FHIR Resources from the PDex and HRex IGs that are used to support the data exchange:

Other Dependent FHIR Resources

Value Sets and Terminologies

Identify the value sets, codings and terminologies that will support the data exchange.

Terminologies

Data Crosswalks

Data Preparations

Identify the dependencies for creating FHIR resources.....

For example, Patient and Practitioner Resources need to be created before Encounter, Procedure etc.
