Final answer:
The statement is false; the UMLS includes both terminologies and classifications. It is a comprehensive system that encompasses various biomedical vocabularies, allowing for effective connection and use of health-related information.
Step-by-step explanation:
The assertion that the UMLS (Unified Medical Language System) includes terminologies but excludes classifications is false. The UMLS is a comprehensive, compendium of many healthcare and biomedical vocabularies developed by the National Library of Medicine. It includes not only terminologies, which are lists of terms representing the system of concepts of a particular subject, but also classifications, which are systematic arrangements of those terms in hierarchical structures or categories.
For example, in the UMLS, you can find terminologies like SNOMED CT (Systematized Nomenclature of Medicine—Clinical Terms) and classifications like ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification). The inclusion of both terminologies and classifications ensures that various types of health-related information—from clinical care to research and public health reporting—can be connected and utilized effectively.
