This pull request updates the existing concept mappings for the
chartevents
andprocedureevents
tables, and adds new mapping files for clinical concepts from thelabevents
andprescriptions
tables in MIMIC-IV v2.0, as well as from the Northwestern ICU (NWICU) database.These mappings align local concept identifiers (
itemid
,ndc
) with standard clinical vocabularies, including LOINC, RxNorm, SNOMED, and OMOP, to support interoperability across ICU datasets.All mapping files are formatted according to the Simple Standard for Sharing Ontology Mappings (SSSOM) specification @sssom.
