The hl7 from arebgun

hl7's Introduction

Overview

HL7v2 stands for "Health Level 7: Version 2" - a specification for shuttling clinical data around and between medical institutions. While working on Medtasker with Nimblic, I've written this library for reading the protocol and querying the messages it contains.

I have a blog post on my website if you'd like to hear a bit more of the story.

New Features

This fork adds the ability to Unpack() a Message or Segment into a struct using tags

package main

import (
	"fmt"
	"github.com/nwehr/hl7"
	"strings"
	"time"
)

var testMessage = strings.Replace(`MSH|^~\&||GA0000||VAERS PROCESSOR|20010331605||ORU^R01|20010422GA03|T|2.3.1|||AL|
