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

NEMSIS HL7 Process

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

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

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
