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
Commercial Support
No commercial support was received for this activity.
Disclosure Policy
As a provider accredited by the ACCME, AMIA requires that everyone who is in a position to control the content of an educational activity disclose all relevant financial relationships with any commercial interest for 12 months prior to the educational activity.
