Chapter 2: Pros and Cons of Interfacing Capabilities
Also available at: http://caristix.com/blog/2012/11/hl7-survival-guide-chapter-2/


This guide is for healthcare integration analysts and their managers. HL7 interfacing and interoperability – you can’t live without it but that doesn’t mean you have to suffer as you work to connect the systems that make your environment hum along. This guide will help you get a firm grasp on all the challenges, standards, and choices you need to make along the way, whether you’re developing interfaces on your own or working with a third party.

  • 4. HL7 SURVIVAL GUIDE CHAPTER 2 4• Point to point interfaces?• Interface engine?• Integration engine? How do you make a good choice among these interfacing approaches?• You need to look at their advantages and trade-offsWWW.CARISTIX.COM SHARE THE SLIDEDECK
  • 5. HL7 SURVIVAL GUIDE CHAPTER 2 5POINT-TO-POINT INTERFACES: ADVANTAGES• Up and running quickly• Fewer systems? Point-to-point makes sense• Cost-effective for fewer than five healthcare information/clinical systems – Minimal infrastructure investment, reduced complexity• No interfaces? Start from scratch more easily• No need for technical resources; vendors can set up interfacesWWW.CARISTIX.COM SHARE THE SLIDEDECK
  • 6. HL7 SURVIVAL GUIDE CHAPTER 2 6POINT-TO-POINT INTERFACES: TRADE-OFFS• Harder to grow. – Systems are tightly coupled. Change one, impact all.• Less scalable. – There will be N(N-1) interfaces in ecosystem – E.g., 5 systems – 5(5-1) = 20 interfaces• Inflexible: systems must understand other systems’ expected data structure and semantics• Limited monitoring capabilities• Costs can grow rapidly if you rely on vendor to change or add new interfacesWWW.CARISTIX.COM SHARE THE SLIDEDECK
  • 7. HL7 SURVIVAL GUIDE CHAPTER 2 7INTERFACING CAPABILITIES: ADVANTAGES• Mediates transport protocols between systems• Scales elegantly to reduce number of interfaces required (N + 1)• Centralizes and facilitates monitoring of message flows and interfaces• Systems are loosely coupled – Add new interfaces and modify existing ones without impacting other systems• Interface adapts to different HL7 message and data formats• Reduces interface costs by using single application capabilities across all applications• Reduces dependency on multiple vendors for changes to message formatWWW.CARISTIX.COM SHARE THE SLIDEDECK
  • 8. HL7 SURVIVAL GUIDE CHAPTER 2 8INTERFACING CAPABILITIES: TRADE-OFFS• Steep learning curve – need to be well-versed in a specific engine vendor’s technology to develop interfaces• Vendor lock-in can mean additional costs for integration engine infrastructure, as well as costly interface engine technology conversion that involves large projects impacting several systemsWWW.CARISTIX.COM SHARE THE SLIDEDECK
  • 9. HL7 SURVIVAL GUIDE CHAPTER 2 9INTEGRATION CAPABILITIES: ADVANTAGES• Includes workflow management features – Interfaces can respond as clinical workflows evolve – More flexible migration path for systems and ecosystems• Provides a single point for system integration to ensure consistent management• Technology is built to scaleWWW.CARISTIX.COM SHARE THE SLIDEDECK
  • 10. HL7 SURVIVAL GUIDE CHAPTER 2 10INTEGRATION CAPABILITIES: TRADE-OFFS• More complex and expensive than smaller-scale interface engine due to shortage of skilled analysts and need for extensive training• Expensive software licenses• Need to create a dedicated team (if you don’t already have one)WWW.CARISTIX.COM SHARE THE SLIDEDECK
  • 11. HL7 SURVIVAL GUIDE CHAPTER 2 11VENDORS OF INTEGRATION ENGINES AND TECHNOLOGIES• Vendors address different needs – Some serve small hospitals – Some scale to support multiple locations and stakeholders – Some are vendor-specific: for example, Summit and Iatric are fairly Meditech focused.• Evaluate based on Advantages and Trade-offs listed earlierWWW.CARISTIX.COM SHARE THE SLIDEDECK
  • 12. HL7 SURVIVAL GUIDE CHAPTER 2 12VENDOR LIST(partial list – we welcome your suggestions!)• Cerner Open Engine• Corepoint Health• Iatric EasyConnect• InterSystems Ensemble• Interfaceware Iguana• iWay• Lawson Cloverleaf• McKesson Pathways• Microsoft BizTalk• Mirth Connect• Oracle Fusion• Oracle JCAPS/ICAN/e*Gate/DataGate• Orion Health Rhapsody• Siemens OpenLink• Summit• Sybase e-Biz ImpactWWW.CARISTIX.COM SHARE THE SLIDEDECK
