Wording Standardization: Building a Foundation for Health Information Exchange Siew Lam, MD Sarah Maulden, MD

Slide 2

Terminology "Interoperability is the capacity of a framework or an item to work with different frameworks or items without uncommon exertion with respect to the client." (www.searchsoa.com)

Slide 3

Types of Terminology Interoperability Internal : helps us assemble the Health Data Repository (HDR) with institutionalized information from 128 VistA destinations Interagency : VA and DoD bi-directional information trade VA and different offices, for example, CDC and IHS External : VA with the outside world All Standards & Terminology Services (STS) work to make and keep up phrasing substance and administrations bolsters interoperability both inside and with the non-VA people group—with almost no unique exertion with respect to the client. 1Middleton et al. Wellbeing Affairs (Millwood). 2005 Jan-Jun;Suppl Web Exclusives Terminology Interoperability 3

Slide 4

Presentation Topics Overview of Standards & Terminology Services (STS) Why Terminology Standardization is imperative to interoperability? Advancement to date and progressing exercises Real World Example: Use of SNOMED CT in CHDR Question and Answer

Slide 5

Standardization Defined Terminology Standardization is the recognizable proof, appropriation, usage, confirmation, upkeep, and consistence observing of information measures Terminology Standardization is foundational to processable, interoperable information sharing over a medicinal services data base

Slide 6

Goals of Standardization Ensure steady translation of clinical data Support clinical basic leadership Support interoperability with human services accomplices Support general wellbeing and bio-observation exercises Improve quality, security, and cost-viability of patient consideration

Slide 7

What Does STS Do? STS is delivering: Terminology Content and Model Standard code sets, both inward made and remotely got A wording model that blueprints how the phrasing will be utilized Terminology Services VistA Terminology Services Clinical HeV Services Non-clinical HeV Services

Slide 8

What Does STS Do? Exercises/Projects attempted to create substance and administrations are: Clinical Data Standardization Allergies, Problem List, Document Titles, and so on. Authoritative Data Standardization Standard Data Services (SDS), Demographics Health e Vet Terminology Pharmacy Re-building, Lab Re-designing, and so forth. Interagency Interoperability CHDR, Lab Data Sharing and Interoperability (LDSI) Terminology Maintenance New Term Rapid Turnaround (NTRT), VistA Lexicon

Slide 12

Ensuring Accurate Term Maintenance There are essential 2 worries with guaranteeing precise phrasing upkeep: Selecting the right terms to add to the national standard Seamlessly upgrading VistA records in a quick way The NTRT procedures and frameworks moderate potential issues with each

Slide 13

New Term Rapid Turnaround (NTRT) New Term Rapid Turnaround (NTRT) – the support procedure for standard information which incorporates: Receiving submitted terms from clients Analyzing entries to decide reasonableness in the standard Deploying new terms by pushing them to VistA

Slide 17

Domain Review Teams The Domain Review Teams decide the propriety of another solicitation for option to the national standard Team made up of wording colleagues and end clients (topic specialists) The Review Team may prescribe options to the standard or that the requester utilize a current term

Slide 18

Ensuring Accuracy in NTRT Once a term has been endorsed for the standard numerous means are set up to guarantee exact NTRT pushes including: 2 nd audit of all wording composing Internal testing underway like VistA record Independent SQA testing Terms at 4 test locales for 24-hours preceding national discharge

Slide 19

NTRT Totals Total New NTRT Terms Deployed to VistA (through May 2008) Vitals 15 Allergies 137 Document Titles 314

Slide 20

STS Services - VistA Standardization Tools for separating, examining, and mapping VistA information These apparatuses are indispensable to the general VistA institutionalization exertion VistA Lexicon Tools Provide access and upkeep devices for the VistA Lexicon NTRT Update Tools Allows redesigns to institutionalized wording records

Slide 21

STS Services – Health e Vet Clinical VA Enterprise Terminology Services (VETS) – Java/Oracle-based advancement which incorporates: Terminology Deployment Services (TDS) Allows Terminologists to plan, test and convey wording to VA frameworks New Term Rapid Turnaround (NTRT) Web Applications Allows field-clients to ask for new terms and track entries through a web interface Terminology Services Allows different applications to get to phrasing content VA Unique Identifier (VUID) Services Provides VUIDs through an API or a web interface *Terminology Development Environment (TDE): A phrasing writing instrument that is authorized from Apelon yet coordinates with alternate VETS devices

Slide 22

STS Services – Non-Clinical Standard Data Services (SDS) – Java/Oracle-based improvement which incorporates: Creation and support of Non-Clinical expressions for use in HeV applications Example – demographic information, postal divisions, and so on. SDS terms principally put away in the Administrative Data Repository (ADR) Initial execution to bolster Enrollment Systems Redesign (ESR) and Replacement Scheduling Application (RSA)

Slide 23

Mapping Services PRE Re-designing Lab-R Import usefulness HeV Services VETS CHDR Services Vista Deployment Services Vista Lexicon Vista VETS Services Current VETS administrations give the capacity to make and keep up current wording models and also giving an establishment to bolster future advancement of an extensive variety of administrations to meet VA business needs

Case Study – Real World Example Using SNOMED CT as a Mediation Terminology

Slide 25

Using SNOMED CT as a Mediation Terminology Mapping Issues, Lessons Learned, and Next Steps Toward Achieving Semantic Interoperability

Slide 26

Overview Background: Consolidated Health Data Repository (CHDR) venture Introduction to SNOMED CT Terminology Mediation Using SNOMED CT for Allergy Reactions: Methods and Results Discussion: Lessons Learned Next Steps

Slide 27

Introduction The President has requested Federal offices to advance enhanced social insurance quality and effectiveness through secure, standard-based information trade The Clinical Data Repository/Health Data Repository (CHDR) venture trades clinical data between Department of Veterans Affairs (VA) and Department of Defense (DoD) CHDR trades institutionalized, calculable information instead of content, permitting information to be utilized as a part of electronic choice backing

Slide 28

Interoperability Technical interoperability frameworks can dependably trade data without mistake; printed information trade Computable Semantic Interoperability Enables elucidation of the traded data Requires a mutual structure for transmission and a typical electronic vocabulary Enables mechanized request checks and alarms crosswise over foundations

Slide 29

DoD CDR/Terminology Translation VA STS Terminology Translation Service SCT: 300359004 DoD makes an interpretation of the information to a SNOMED CT code and sends it to VA through the CHDR structure DoD Clinician enters a sensitivity response ("regurgitating") for a patient on erythromycin. Information is put away in DoD Clinical Data Repository (CDR) STS Services makes an interpretation of from SNOMED CT to VA Unique ID (VUID) for capacity in VA HDR VA Hospital DoD Hospital VUID: 4691049 VA HDR Allergy can be utilized as a part of Decision Support inside VistA framework CHDR Example: DoD Data in VistA

Slide 30

VA-DoD CHDR Project Pharmacy and hypersensitivity information are traded by means of CHDR amongst VA and DoD for patients acquiring care in both frameworks Allergy responses are traded utilizing SNOMED CT, as per Health Information Technology Standards Panel (HITSP) suggestions Each office maps its sensitivity responses to Systematized Nomenclature of Medicine – Clinical Terminology (SNOMED CT); the SNOMED CT codes are then traded

Slide 31

Introduction to SNOMED CT SNOMED CT was created by the College of American Pathologists (CAP) Ongoing improvement, quality affirmation, and circulation are presently overseen by the non-benefit International Health Terminology Standards Development Organization (IHTSDO) (www.ihtsdo.org) Versions of SNOMED have been being developed subsequent to 1965; the present variant contains 90% of phrasing required today in human services Latest discharge contains > 357,000 wellbeing related ideas assembled from different clinical gatherings including drug, nursing, research facility and drug store .:tsli
