This support guide includes a Planning Methodology, Design and Implementation Methodology, HL7 Transaction Checklist and HL7 Message Diagrams in addition to the MLLP protocol.

TARGETS

• Healthcare IT Vendors
• Healthcare Providers

BENEFITS

• Provides the methodologies and strategies for successful implementation of the Version 2.x standard

IMPLEMENTATIONS/CASE STUDIES

• 95 of US healthcare organizations use HL7 Version 2.x
• 35 countries have HL7 Version 2.x implementations

DEVELOPMENT BACKGROUND

Institutions that are considering major systems development activities (e.g. comprehensive system upgrades/replacements), migration to an open systems architecture and/or integration of various clinical, financial or administrative systems with a central Hospital Information System (HIS) - and are considering HL7 as a mechanism for integrating these systems should refer to the planning component of the methodology.

 

It is critical when planning for implementation of a multi-system environment that an overall systems strategy and technical architecture be established. These strategies will help guide the healthcare institution through critical issues such as how information technology will be utilized to support business goals and objectives.

 

Due to its widespread use, Version 2 will continue to play an integral part in healthcare messaging, even with the HL7 Version 3 Normative Edition. HL7 is committed to supporting and extending Version 2 in parallel with Version 3, providing continuity for current installations.
