PMS_DN uses the Apache cTAKES NLP engine to extract occurrences of UMLS concepts in the clinical notes of PMS patients. The UMLS concepts are mapped to 20 different terminologies including ICD‐9, ICD‐10, SNOMED, MeSH, and NDFRT. The i2b2/tranSMART user interface allows for easy browsing—starting with broad biomedical concepts and drilling down to find specific patients and data of interest. The i2b2/tranSMART user interface also displays the counts of patients (PC) and distinct terms (DTC) associated with each concept at all levels of the hierarchy [Color figure can be viewed at http://wileyonlinelibrary.com]
