NCI EVS works closely with other members of the NIH community to develop shared terminology resources and standards, improving the quality and efficiency of our shared research mission as well as the exchange and reuse of data. These noteworthy examples of collaboration and reuse within NIH are included below:
National Library of Medicine (NLM)
Since its inception, EVS has worked with NLM on a variety of terminology content and technology efforts. EVS licenses content from and harmonizes with NLM's Unified Medical Language System (UMLS), building NCIm by modifying and extending a subset of the UMLS Metathesaurus and using NLM editing software.
NCI is also a contributor to the UMLS, for example, providing monthly builds of NCIt for inclusion in UMLS. (UMLS only publishes twice yearly; they pull whichever build is most current at the time they begin processing.) EVS also worked with NLM and other federal partners to develop the Federal Medication Terminologies framework for harmonized medication coding (see below). EVS staff provided start-up phrase dictionaries and search criteria for the PubMed Cancer Subset, and jointly maintains this content with NLM on an ongoing basis.
NLM's DailyMed gets over 10 million hits each month, and each of the SPL files in DailyMed uses terminology that is maintained by NCI. There are over 27,000 SPL files on DailyMed, and another 5,000 SPL files that are not on DailyMed. Each of these SPL files requires NCIt codes.
NCI and National Human Genome Research Institute (NHGRI)
The Cancer Genome Atlas (TCGA) is a joint effort between NCI and NHGRI, developing a database of the changes that occur in the genome, associated with a specific cancer type. TCGA creates a national network of research and technology teams, and provides a mechanism for pooling results; data are publicly available. 25 Studies are associated with this data, and data are being actively submitted or used by 16 academic and research organizations, 27 commercial organizations, and 17 non-profit organizations. EVS supports terminology for annotating the CDEs for tagging information and samples, mainly cell and specimen type, with information about tumor size, anatomic location, sample preparation, and patient demographics.
National Heart, Lung, and Blood Institute (NHLBI)
Since 2005, NHLBI and EVS have jointly developed terminology in NCIt for various projects including bone marrow transplant clinical trials and the Family Blood Pressure Program. Duke, through an NIH Roadmap project, the American College of Cardiology, and CDISC, have also collaborated with EVS to produce several cardiovascular data standard sets now in use at NHLBI, with a portion incorporated into CDISC SDTM.
National Institute of Child Health and Human Development (NICHD)
Since 2009, NICHD and EVS have jointly developed terminology in NCIt for pediatric terminology, including standardizing data for newborn screening forms, through the Pediatric Terminology Harmonization Initiative, developed to assist Pediatric clinical researchers. This is associated with 848 NICHD Clinical Trials, and is being used by 52 different academic and research organizations.
National Institute of Dental and Craniofacial Research (NIDCR)
Since 2008, NIDCR and EVS have jointly developed terminology in NCIt for dental treatments and medical procedures.
NIH Biomedical Translational Research Information System (BTRIS)
Collaboration includes planned EVS publication of the BTRIS Research Entities Dictionary (RED) in support of NIH researchers' coding, retrieval, and analysis of clinical research data stored in BTRIS. RED began with NCIt as a foundation.
NCIt is one of four NIH-approved terminologies for grant coding, and EVS has helped develop the Research, Condition and Disease Categorization (RCDC) grant coding system.
