MEDI - an Ensemble MEDication Indication Resource
MEDI (MEDication Indication) is an ensemble medication indication resource for primary and secondary uses of electronic medical record (EMR) data. MEDI was created based on multiple commonly used medication resources (RxNorm, MedlinePlus, SIDER 2, and Wikipedia ) and by leveraging both ontology and natural language processing (NLP) techniques.
MEDI contains 3,112 medications and 63,343 medication-indication pairs. The MEDI high precision subset (MEDI-HPS) includes indications found within either RxNorm or at least two of the three other resources. MEDI-HPS contains ~13,400 unique indication pairs regarding 2,136 medications. The average (±standard deviation) number of indications for each medication in MEDI-HPS is 6.22±6.09. The mode for each medication is 2 while the median is 4. The estimated precision MEDI-HPS is >92% based on physician review.
