  4. 4. WWW.CARISTIX.COM SHARE THE SLIDE DECK HL7 SURVIVAL GUIDE CHAPTER 9 Now that you know what is needed to test your interface, you need to feed the right message samples and test messages. 4 What makes messages right?
  5. 5. WWW.CARISTIX.COM SHARE THE SLIDE DECK HL7 SURVIVAL GUIDE CHAPTER 9 Sample messages and test messages that reflect your environment: • Your ADT message flow • Your specific lab codes and text messages • Your case mix For testing: • Sample messages give you custom formats, structure and data values. • Look at the issues highlighted during gap analysis. • Make sure your messages cover your use cases. 5 What Makes Messages Right?
  6. 6. WWW.CARISTIX.COM SHARE THE SLIDE DECK HL7 SURVIVAL GUIDE CHAPTER 9 You need production data. • Once you have the right message samples and test messages. • Make sure you have a sufficient volume of quality test data. • Make sure your productions data reflects the data you work with day in and day out. – Both data type and format as well as volume • The result: – Accurately test for load and performance. – Avoid message workflow problems that can bring down interfaces. 6 Go with Production Data
  7. 7. WWW.CARISTIX.COM SHARE THE SLIDE DECK HL7 SURVIVAL GUIDE CHAPTER 9 7 It All Starts with De-identification • You can’t use real production data • Remove protected health information (PHI) • Use de-identification – Keep the clinical workflow in the messages – Remove the patient identifiers – Replace them with fake values – Use off-the-wall fake values for edge cases – Makes sure those scenarios match your workflows • Employer information can contain PHI – Remove employer name or insert replacement names – Easy to re-identify data through information source For more on de-identification, check out these blog posts.
  8. 8. WWW.CARISTIX.COM SHARE THE SLIDE DECK HL7 SURVIVAL GUIDE CHAPTER 9 Here’s what to keep in mind when you de-identify your production data: • Satisfy HIPAA. Remove the 18 identifiers designated by HIPAA as protected health information (PHI). • Maintain message flow. If “John Doe” in your production data becomes “Michael Smith” in your test log, ensure that Michael Smith in your A01 admission message is the same Michael Smith upon discharge. • De-identify data in z-segments. PHI can hide in z-segments. • Log volume. Aim for at least a week’s worth of messages and ideally a few months’ worth. • Traceability. Record which data was de-identified and which fields and data types were transformed. 8 De-identification of Production Data
  9. 9. WWW.CARISTIX.COM SHARE THE SLIDE DECK HL7 SURVIVAL GUIDE CHAPTER 9 • Without the right message samples and test messages, you can run into issues with the lack of updated vocabulary and potential for downtime if messages contain unexpected values. • Confirm that you are not introducing errors. Caristix Cloak software removes protected patient information in HL7 messages. Cloak produces auditable reports of de-identification. Generate clinically valid data for interface development, testing and analytics. 9 Avoid Problems with Updated Vocabulary
  10. 10. WWW.CARISTIX.COM SHARE THE SLIDE DECK HL7 SURVIVAL GUIDE CHAPTER 9 If your new to interfacing, you might think about just hitting Google for some sample messages. If you do, some basic structure like pipes and carets might be right. But: • You won’t have information about the interface you are trying to build: – The message types it uses – The segments and fields – Positions – Optionality • Developers need the information in messages in order to build a solid set of requirements for the actual interface. • To develop a viable interface, work with realistic messages. • In addition, whatever you find on the internet will be practically used due to security measures. 10 Don’t Fall into the Beginner’s Trap
