Overview
EXTraction of EMR Numerical Data (EXTEND) is a natural language
processing (NLP) tool that can efficiently extract numerical clinical data
from different type of narrative notes with high accuracy. By expanding the
dictionary and developing new rules, the usage of EXTEND can be easily
expanded to extract additional numerical data important in clinical
outcomes research.
EXTEND was developed by Tianrun Cai at Brigham and Women’s Hospital, Katherine P. Liao at Brigham and Women’s Hospital, Frank Rybicki at University of Ottawa, Tianxi Cai at Harvard T.H. Chan School of Public Health.
