Title: A comparison of the language of patient charts at Presbyterian University Hospital, Pittsburgh, Pa., and the Unified Medical Language System of the National Library of Medicine

Abstract: This dissertation matches the language of online medical records at the Presbyterian University Hospital in Pittsburgh with the language of the Unified Medical Language System (UMLS), an experimental thesaurus of biomedicine developed by the National Library of Medicine. In the future, the UMLS may serve as an interface between medical charts and the information in databases such as Medline. The main research question is whether the UMLS captures the concepts found in medical charts and can thus be used to bridge the gap between chart terminology and MeSH, the vocabulary used to access Medline.

A sample of 50 records from two diagnoses was compared to the UMLS. A statistical formula selected potentially useful non-matches, which were then analyzed to determine whether the missing concepts are wholly or partially present in another form in MeSH.

Seventy percent of the missing terms are either broader terms than MeSH headings or synonyms of chart terms/concepts. Approximately 19% of the dropped terms could not form a strong map to MeSH. The study indicates that, since so many chart terms are found in some form, a chart-generated search can link to many related concepts in MeSH, but a significant number of chart concepts must be added to the UMLS or cross referenced to MeSH.
