  1. National EMS Information SystemEMS Software DevelopersMeeting October 20, 2009 Dallas, Texas

  2. Test your Data Acronym Knowledge • NHII: National Health Information Infrastructure • DHHS: Department of Health and Human Services • ONCHIT: Office of the Coordinator for Health Information Technology • ANSI: American National Standards Institute • HITSP: Healthcare Information Technology Standards Panel • EMAR: Emergency Medical Awareness and Response • OASIS: Organization for the Advancement of Structured Information Standards • HL7: Health Level 7

  3. Health Level 7 • Standards Developing Organization • ANSI Approved • ISO Component • Health Related Standards • Most Important is CMS Claims • Several Versions • Version 2.5 = 95% US Hospital Market • Version 3.0 = Majority European Market • XML Based = NEMSIS Target

  4. NEMSIS HL7 Process

  5. Data Dictionary Changes Normalization

  6. Data Dictionary Changes Usage Constraints • Required = the data element MUST be completed but will accept null values. • Mandatory = the data element MUST be completed and will NOT accept null values • Optional = the data element is NOT required and will NOT accept null values

  7. Data Dictionary Changes Null Values • Not Reported = the data element is not being collected by the EMS software • Not Recorded = the data element is collected by the EMS software but was not recorded by the user • Not Applicable = the data element was not applicable or pertinent to the EMS event

  8. Data Dictionary Changes Negative Action Values • Yes = the data element value was the negative of the indicated value. This is used to document that the action was done but the value was negative. This is used in three areas: • Assessment Example: NOT Tenderness • Medication Example: Aspirin NOT Given • Procedure Example: IV NOT Started • No = the default indicating that the value did not have an Negative Action Value

  9. Data Dictionary Changes Negative Action Reason • Exam Finding Not Present • Medication Already Taken • Medication Allergy • Refused • Unable to Complete • Contraindication Noted • Denied by Order

  10. Data Dictionary Changes Vocabulary Requirements • Defined Data Element • Standardized Vocabulary • Not owned by HL7 • Owner examples SNOWMED, LOINC, RXNORM • Version • Associated Codes • If no existing Vocabulary • Extend an existing vocabulary • Create a new one

  11. Decision Point

  12. Decision Point

  13. NEMSIS V3 Draft 2 Release now January, 2010 • Include Full Dataset with Vocabulary based on HL7 Process • Include Business Logic • Include National Data Elements • Include Potential Performance Measures • Include State Data Elements

  14. NEMSIS Transition Process NEMSIS Version 3 Products NEMSIS HL7 Products

  15. Version 3 Draft

  16. Lunch

  17. Version 3 DraftPublic Comments

  18. NEMSIS Version 3 Draft 1

  19. Version 3 Comments Concern over conversion from FIPS to GNIS and ANSI • Zip Codes are not connected • City, State, County, and Country are in ANSI • GNIS is more location information for specific entities such as parks, rivers, etc. Concern on how to collect Census Tract

  20. Version 3 Comments Destination Facility Codes • No uniform code across physical locations • CMS codes account for the corporate entity • AHA code is hospital only • States have different numbering schemes

  21. Version 3 Comments Procedure Codes • Even with vocabulary standardization there is a no clear way to add new procedures in a timely fashion • Standard vocabularies in SNOWMED and ICD-9 (or 10) do not account for device types within a procedure • Blind Insertion Airway could be LMA, King LT, Combitube, Cobra, etc.

  22. Version 3 Comments Multi-State • Need ability to have several state specific licensure information for each • Agency • Vehicle • EMS Professional

  23. Version 3 Comments Billing • Additional space needed for address • Consider a Address Line 2 implementation • Need to associate location code with text name of the location • Certificate of Medical Need is now “Physician Certification Statement” • More information needed for documentation • Improve CMS Condition Codes

  24. Version 3 Comments Documentation of Complaint and Impression • Lists are incomplete • Current implementations have left the NEMSIS standard and are not usable • Need some type of controlled “Other” • Confusion on Fall height (0 = feet or head) Separate Cardiac Rhythm from 12 Lead ECG interpretation

  25. Version 3 Comments Patient Care Protocols • Need to standardize topic and to some degree content • NASEMSO Medical Directors assisting in an initial master list • How do we maintain it across states • How do we expand it in the future but keep in standardized for analysis

  26. Version 3 Comments State Specific Content • Need more robust implementation for state specific content • Method for states to add content without breaking the NEMSIS XSD or dataset definitions • Expansion of dataset has worked in some cases but not many others

  27. NEMSIS Version 3Compliance Process

  28. Compliant Software • Gold Compliant • 40 • Silver Compliant • 40

  29. NEMSIS Version 2Compliance Testing Active Cycle • September 2009 Version 2 Cycles Remaining • 

  30. A Software Perspective Goal • Standardized Dataset across the market • Standardized Data Transmission • Quality Data Collection • Easy configuration, implementation, maintenance • Valid data • Complete Data based on the event scenario • Positive User Experience • Real Time data application

  31. NEMSIS Version 3 Compliance Components • Software • Data Definition Standard • Business Rules • Data Exchange Standard • Data Exchange Method

  32. No Silver or Gold Only NEMSIS Version 3 Compliance EMS State Medical Device Billing CAD Trauma

  33. Data Standard Local EMS Software State EMS Software All EMS Data Elements and Demographic Data Elements Required All EMS Data Elements Required Demographic Data Elements Optional

  34. Business Rules The Winner is? Schematron • Multiplatform • Combine XSD • Structure • Business Rules • EMS Dataset Only • Web-Services Development Tool

  35. Transmission Standard (XML) Modular Design to XSD • State Specific Module • NEMSIS Specific Modules • Demographic Content in EMS Header Compliance Concepts • State Specific can be altered by each state • NEMSIS cannot be altered • NEMSIS Website would be XSD source

  36. Data Exchange Method Web Services • Standard API • Web Services Definition Language (WSDL) • Development Test Implementation • Send • Receive • All XML Types

  37. Version 3 Draft

  38. Version 3 Development Tools • Web-Based Validator • Schematron based • Structure • Business Logic • Web Services Test Site • Send • Receive • All XSD Types • Development Test Cases

  39. How Do We Test? Version 3 Testing EMSPIC in North Carolina NEMSIS TAC in Utah

  40. Discussion

  41. NEMSIS 2010:Interim Challenges and Opportunities

  42. Lessons Learned

  43. Opportunities Version 2 Enhancements? Business Logic Web-Services Opportunity to begin development and testing of Version 3 Concepts?

  44. Next Meeting NEMSIS V3 Draft 2 out in January, 2010 NEMSIS V3 Final March or April, 2010 Communication Options • Webinar in November, 2009 • Webinar or meeting during Draft 2 Comment Period in February, 2010? • Webinar or meeting after NEMSIS V3 Final for Software Development?
