EXTraction of EMR Numerical Data (EXTEND) was developed by Tianrun Cai at Brigham and Women's Hospital. Serving as a natural language processing (NLP) tool, EXTEND is tailored to efficiently extract numerical clinical data such as vital signs, laboratory test results, and ejection fraction measurements from narrative notes with exceptional accuracy. By expanding its dictionary and devising new rules, EXTEND can easily incorporate additional numerical data crucial for clinical outcomes research.
