Effect of vocabulary mapping for conditions on phenotype cohorts

Lead author George Hripcsak will discuss this month's JAMIA Journal Club selection:

Hripcsak G, Levine ME, Shang N, Ryan PB. Effect of vocabulary mapping for conditions on phenotype cohorts. J Am Med Inform Assoc. 2018 Dec 1;25(12):1618-1625. doi: 10.1093/jamia/ocy124.

Presenter

George Hripcsak, MD, MS
Vivian Beaumont Allen Professor of Biomedical Informatics and Chair
Department of Biomedical Informatics, Columbia University;
Director of Medical Informatics Services, New York-Presbyterian Hospital/Columbia Campus
New York, New York

George Hripcsak, MD, MS, is a board-certified internist with degrees in chemistry, medicine, and biostatistics. Dr. Hripcsak’s research focus is on the clinical information stored in electronic health records and on the development of next-generation health record systems. He leads the coordinating center for Observational Health Data Sciences and Informatics (OHDSI), which has 200 researchers from 25 countries and generates evidence from data on about 500 million unique patients.

Format

  • 30-minute discussion between the authors and the JAMIA Student Editorial Board moderators including salient features of the published study and its potential impact on practice.
  • 30-minute discussion of questions submitted by listeners via the webinar tools and moderated by JAMIA Student Editorial Board members

Student Access

Students who are not AMIA members, but whose academic institutions are members of the Academic Forum, are eligible for a complimentary JAMIA Journal Club registration. Please contact Susanne Arnold at susanne@amia.org for the discount code. In the email, please include: full name, Academic Department, and the primary Academic Forum representative of that Academic Department. Note that AMIA Student memberships are $50, which allow access to JAMIA, all JAMIA Journal Clubs, and other webinars of interest to the biomedical informatics community. 

Statement of Purpose

To combine data from multiple sources or databases, coded information is sometimes mapped to a common vocabulary so that future researchers can create simpler, more coherent phenotype definitions, saving time and perhaps improving accuracy because researchers may not be conversant with multiple vocabularies. The mapping, however, may lose information or introduce inaccuracies. Previous work has shown that mappings can indeed alter generated phenotype cohorts, although the results of the associated studies were unaffected by the mapping. Another study showed that mapping among vocabularies swaps classification hierarchies, again resulting in different cohorts.

Health informatics researchers will want to learn how Hripcsak, et al set out to study the effect on patient cohorts of mapping diagnosis codes from source billing vocabularies to a clinical vocabulary. If researchers find this approach generalizable, it may improve the efficiency and transportability of research.

Target Audience

The target audience for this activity is professionals and students interested in biomedical and health informatics.

Learning Objectives

The general learning objective for all of the JAMIA Journal Club webinars is that participants will

  • Use a critical appraisal process to assess article validity and to gauge article findings' relevance to practice

After this live activity, the participant should be better able to:

  • Weigh the benefits and challenges of using a research strategy that maps diagnosis codes from source billing vocabularies to a clinical vocabulary
