1 HL7 Overview

2 CONFIDENTIAL TRN Rev 04/13/06 2 Learning Objectives Define “HL7” Understand the basic structure of HL7 messages Understand typical usage of HL7 messages Understand common message content and workflow

3 CONFIDENTIAL TRN Rev 04/13/06 3 Table of Contents Terminology Introduction Overview Summary

4 CONFIDENTIAL TRN Rev 04/13/06 4 Terminology

5 CONFIDENTIAL TRN Rev 04/13/06 5 Terminology Message Types are messages that reference a group of related actions (example: ADT) Trigger Events are specific actions that are associated with the generation of a message (example: ADT_A01) Segments are logical groups of data elements or “fields” (example: PID)

6 CONFIDENTIAL TRN Rev 04/13/06 6 Introduction

7 CONFIDENTIAL TRN Rev 04/13/06 7 Introduction Health care organizations often operate numerous information systems and integrate them via data transfer interfaces HL7 (Health Level 7) is the name of the organization and the predominant messaging standard for exchanging key sets of administrative and clinical data in the healthcare enterprise The cross-departmental usage of HL7 leads to the use of some generic labels Example: Diagnostic Service Section ID (~AE Title) and Universal Service ID (Procedure Code)

8 CONFIDENTIAL TRN Rev 04/13/06 8 Introduction Departmental system databases typically store a combination of redundant and unique data The most common redundant data are patient IDs and demographics Health care organizations usually assign primary responsibility for correctly identifying patients to a single department that manages the data in a single system

9 CONFIDENTIAL TRN Rev 04/13/06 9 Introduction The department(s) with primary responsibility for patient ID usually use(s) a system commonly referred to as a Healthcare Information System (HIS) Typical HIS functions are registration/admitting, and billing Order entry, claims, clinical viewing, decision support, and other functions may or may not be supported by the HIS The HIS is regarded as the master system

10 CONFIDENTIAL TRN Rev 04/13/06 10 Overview

11 CONFIDENTIAL TRN Rev 04/13/06 11 What is HL7? –“Health Level Seven develops specifications, the most widely used being a messaging standard that enables disparate healthcare applications to exchange keys sets of clinical and administrative data.” 1 What is a “Message?” –A message is a basic communication unit containing information that models a real world event How does one read a Message? –A message is structured like an organizational chart HL7 Overview Message Segment Fields Component Common HL7 Message Types, Segments, and Fields based on HL7 Standards 1 – About Health Level Seven Source:

12 CONFIDENTIAL TRN Rev 04/13/06 12 HL7 Message Structure Message has contains comprised of User Segments User Fields User Components

13 CONFIDENTIAL TRN Rev 04/13/06 13 Message Types ADT is an (A)dmit, (D)ischarge, and (T)ransfer message that is “triggered” by a patient admission, discharge, or transfer ORM is an (Or)der (M)essage which includes new orders, order status changes, and order cancels ORU is a Report/Result Message Example: MSH|^~\&|IMAGING|PSJMC|TDSresults|PSJMC| || ORM^O01|783744|P|2.3

15 CONFIDENTIAL TRN Rev 04/13/06 15 Typical Message Content and Functions HL7 specifies requirements for SEQs/components but this does not confer an obligation to process this data Conversely, a target application may require data that is not HL7 required HL7 sometimes requires codified data

16 CONFIDENTIAL TRN Rev 04/13/06 16 Typical Message Work Flow ADT-establish patient, visit, update demographics, update visit Example: ADT_A04, A06, A08, A03 ORM-order with account (PID-18) vs. visit (PV1-19), order response, result Example: ORM_O01, ORR_O02, ORU_R01 ORU by definition is unsolicited-does not have to be in response to an order

20 CONFIDENTIAL TRN Rev 04/13/06 20 Summary HL7 is a messaging protocol Message types, trigger events, and segments are identified with 3 character labels; fields are identified by position (SEQ) in segments. Data placement, basic structure, message types, and event definitions should be consistent in HL7 messaging

21 CONFIDENTIAL TRN Rev 04/13/06 21 Summary Due to variations in healthcare business requirements and supported functionality of different information systems there are many variations in HL7 conformance Variation in HL7 data content is present at the message, segment and field level Variation is also present in workflow
