HIT Standards Committee

Clinical Operations Workgroup, Vocabulary Task Force (VTF)

Update on Vocabulary For Stage 2

Jamie Ferguson, Kaiser Permanente

Betsy Humphreys, National Library of Medicine

22 June 2011

current vtf priorities process
Current VTF Priorities & Process
  • ONC Requested Vocabulary Standards for Stage II/III
    • Medications for e-prescribing and medication allergies
    • Lab tests for results reporting and test orders
    • Problems for problem list documentation
    • Standards required to specify quality measures
  • Process:
    • Assess/Revise as necessary Previous HITSC Vocabulary Recommendations for key EHR segments
    • Series of teleconference meetings, next 6/24
    • Work with Clinical Quality WG on Vocabulary Recommendations to support Quality Measures
      • 1st joint CQWG-VTF meeting 6/20; another 6/29?
general issues
General Issues

Can an EHR certification requirement precede a meaningful use requirement in order to facilitate adoption? (Discussed in HITSC meeting 5/18/11)

How will an EHR’s use of vocabulary standards be tested and certified?

VTF has scheduled presentation/discussion with NIST (6/24)

Requirements for subsets used in certification testing could differ from those used to facilitate adoption/use.

EHR products must be able to accommodate (i.e., not reject) any valid value from a required standard vocabulary.

recent relevant developments
Recent relevant developments

May 31 – LOINC Top 2000+ Lab Observations and Mapper's Guidereleased

June 6 – RxNorm Prescribable Drugs subset (1st draft) released

May 26 – IHTSDO and Global Medical Device Nomenclature (GMDN) in formal negotiation re: inclusion of GMDN content in SNOMED CT

allergens allergic reactions
Allergens & Allergic Reactions

Quality Measures require:

medication allergies, non-medication allergens, severity of reaction

Medications/active ingredients - RxNorm (specific named components)


Still under discussion: CVX/MVX, RxNorm

Inactive ingredients, non-medication allergens

Still under discussion: UNII, SNOMED CT

Recent (5/24) recommendations from NCPDP re: allergies suggest incorporation in RxNorm

Severity of reaction - SNOMED CT

Reaction itself – SNOMED CT

medical devices
Medical Devices

For initial (limited) quality measure requirements: SNOMED CT

VTF to monitor developments and make later recommendation re: more detailed device terminology (GMDN, UMDNS)

for action by vtf after joint cqwg vtf meeting 6 20
For Action by VTF (after joint CQWG-VTF meeting 6/20)

Patient characteristics


Non-laboratory Diagnostic Studies

Face-to-face, telemedicine, other communications (e.g., mail, e-mail)

?? Requirements for terminology vs other EHR attributes

For Joint CQWG-VTF discussion (6/29?)

Experience, Family History, Functional Status, Health Record Component, Lab Test Orders, Interventions, Physical Exam, Preferences, Symptoms/Adverse Effects, System Resources
