HDS to FHIR

This project converts JSON data for a patient in the structure used byhealth-data-standards into the HL7 FHIR DSTU2 models defined in the Intervention Engine fhir project.

NOTE: The HDS-to-FHIR conversion focuses only on those data elements that are needed by Intervention Engine. It is not a complete and robust conversion.

Building hdsfhir Locally

For information on installing and running the full Intervention Engine stack, please see Building and Running the Intervention Engine Stack in a Development Environment.

The hdsfhir project is a Go library. For information related specifically to building the code in this repository (hdsfhir), please refer to the following sections in the above guide:

• (Prerequisite) Install Git
• (Prerequisite) Install Go
• Clone hdsfhir Repository

To build the hdsfhir library, you must install its dependencies via go get first, and then build it:

$ cd $GOPATH/src/github.com/intervention-engine/hdsfhir
$ go get
$ go build

For information on using the uploadhds tool to convert HDS patients to FHIR and upload them to a FHIR server, please refer to the uploadhds section of the tools repository README.

Using hdsfhir as a library

The following is a simple example of converting a HDS patient to the corresponding slice of FHIR models:

import (
	"encoding/json"
	"io/ioutil"
	"github.com/intervention-engine/hdsfhir"
)

func ExampleConversion(pathToHdsPatient string) ([]interface{}, error) {
	data, err := ioutil.ReadFile(pathToHdsPatient)
	if err != nil {
		return nil, err
	}

	p := &hdsfhir.Patient{}
	err = json.Unmarshal(data, p)
	if err != nil {
		return nil, err
	}

	return p.FHIRModels(), nil
}
