Version 3 Update

1. Version 3 Update

2. Purpose of NEMSIS Version 3 • Improve Data Quality • Business Intelligence, Schematron • Enhance performance assessment • Incorporation of performance measures • Address need for state flexibility (with control) • Sharepoint, XSD header information • Prepare for next step (HL7) • Synchronization of clinical content • Data Linkage

3. Development and Maintenance of NEMSIS V3 XSD • Generate V3 Data Dictionary from XSD Tables • Software Development tools (i.e. SDK) • Provider data dictionary • XSDs Available Through SharePoint • NEMSIS will provide complete V3 XSDs. • NEMSIS will provide complete national XSD (national required elements). In state folders. • NEMSIS will provide information for chosen state and custom elements along with how state implement extension and new elements.

4. Development and Maintenance of NEMSIS V3 XSD • XSDs Available Through SharePoint (cont’d) • States may post XSD for “custom field” elements, but must demonstrate relationship to compliant NEMSIS element. In state folders. • NEMSIS or states may post “updates” to the XSDs and interested states/vendors will be notified of updates through SharePoint.

5. Development and Maintenance of NEMSIS V3 XSD • Enumerated Tables/Lists Available Through SharePoint • NEMSIS will provide “suggested lists” for NEMSIS elements with value code sets that are expansive or periodically updated (e.g., ICD-10 [procedures], RxNorm [medications], state GNIS, etc). • States may host “suggested lists” associated with NEMSIS lists requiring tailoring to a state, but must demonstrate that list fits the “pattern” for that NEMSIS element.

6. Development and Maintenance of NEMSIS V3 XSD • Develop Calendar Schedule for Review and modification of XSD/Data Dictionary • Must conform with HL7 Balloting process.

7. NEMSIS V3 Custom Elements Overview • Adding a new element outside the NEMSIS V3 Standard • Extending the values of a NEMSIS V3 Element • Select a NEMSIS value first, but provides more details • Adding a value to a NEMSIS V3 Element • Create a new value for an element • Limiting the values of a NEMSIS V3 Element • Do not display an existing value to EMS professional

8. NEMSIS V3 Custom Elements Overview • Think of the NEMSIS elements as a puzzle! NEMSIS Elements XML Schema

9. NEMSIS V3Custom Elements – Adding an Element • Adding an element outside the NEMSIS Standard • e.g., Patient Eye Color V2.2.1 – Research Element V3 – Custom Element NEMSIS Standard Additional Elements

10. NEMSIS V3 Custom Elements – Extending the Values • Extending the values of a NEMSIS Element • e.g., moose vs. car crash (Cause of Injury) • V2.2.1 allowed a “modification” of the Cause of Injury value list • Rolling up into existing value, but this didn’t always happen  result: BAD data nationally & within states EInjury.01 (v3) NEMSIS Standard

11. NEMSIS V3 Custom Elements – Extending the Values • Extending the values of a NEMSIS V3 Element • e.g., car vs. moose crash • V3 – Custom element How is it Implemented? • Dynamically – with Business Intelligence? • Schematron Rule ?  Up to the Developer! End result is the same

12. NEMSIS V3 Custom Elements – Adding a Value • Adding a value to a NEMSIS V3 Element • Adding “police action” to Scene Delay • V3 – Custom element • Utilize Scene Delay eResponse.10 • Choose “police action” among choices • Activates “Safety” in eResponse.10 NEMSIS Standard Additional Elements

13. NEMSIS V3Custom Elements – Adding a Value or Limiting the Values • Adding a value to a NEMSIS V3 element that cannot be associated with an • existing value – CAUTION!! • Limiting the values of a NEMSIS V3 Element • Reason for Choosing Destination eDisposition.20 • Display only: “Closest Facility”, “Protocol”, etc • Hide values: “Family Choice”, “Patient Choice”, etc  Breaks the “spirit” of the standard

14. Development and Maintenance of NEMSIS V3 Business Rules • NEMSIS will develop a core set of business rules, associated with NEMSIS elements, that are to be applied at the “field level” to each EMS record before formal completion and export. • Ensure proper value for applicable elements • Ensure proper use of optional elements • Will allow for errors and warnings • Only warnings for state and national submissions

15. Development and Maintenance of NEMSIS V3 Business Rules • NEMSIS business rules will be technical in nature • No clinical business rules • NEMSIS business rules will be expressed as Schematron script. • States/Software may develop additional business rules for application at the field or state aggregation level. These will be posted in state folder.

16. Development and Maintenance of NEMSIS V3 Business Rules Application of a Schematron file will be required for record level validation, but will not be mandated at levels of case aggregation.

17. Development and Maintenance of NEMSIS V3 Web Services • The NEMSIS WSDL will be revised • Represent a nominal implementation • Require “file size” feature • Optional “search” feature • NEMSIS will develop the standard WSDL and post in state folder. • States may revise the WSDL • NEMSIS will support web services development based upon SOAP or REST.

18. NEMSIS Version 3 Software Capabilities, Requirements, & Compliance
