Semantic Interoperability in Health Information Exchange


Published on

Presented at HIMSS14 Annual Conference & Exhibition, February 26, 2014, Orlando, FL.

Meaningful Use certification requires several large vocabulary standards for representing clinical facts in health information exchange. This presents unique challenges for semantic interoperability such as information loss in translating from and to internal data dictionaries, semantic drift, dealing with legacy content (e.g., ICD-9) and clinical information reconciliation.

Semantic Interoperability in Health Information Exchange

  1. 1. Semantic Interoperability in Health Information Exchange February 26, 2014 Tomasz Adamusiak MD PhD DISCLAIMER: The views and opinions expressed in this presentation are those of the author and do not necessarily represent official policy or position of HIMSS.
  2. 2. Conflict of Interest Disclosure Tomasz Adamusiak Has no real or apparent conflicts of interest to report. © 2014 HIMSS
  3. 3. Learning Objectives 1. Define vocabulary standards for MU 2 2. Define common MU Data Set 3. Identify challenges 4. Propose solutions
  4. 4. HISTORY OF PRESENT INQUIRY: Mr. Smith is a 34-year old gentleman who presents at our branch to obtain a car loan secondary to growing maintenance costs of his current vehicle. He otherwise reports doing well. His past financial history is insignificant.
