Author(s): Shashank Reddy Vadyala*
Colonoscopy is used for Colorectal Cancer (CRC) screening. Extracting details of the colonoscopy findings from free
text in Electronic Health Records (EHRs) can be used to determine patient risk for CRC and colorectal screening
strategies. We developed and evaluated the accuracy of a deep learning model framework to extract information
for the clinical decision support system to interpret relevant free-text reports, including indications, pathology, and
findings notes. The Bio-Bi-LSTM-CRF framework was developed using Bidirectional Long Short-term Memory
(Bi-LSTM) and Conditional Random Fields (CRF) to extract several clinical features from these free-text reports
including indications for the colonoscopy, findings during the colonoscopy, and pathology of resected material. We
trained the Bio-Bi-LSTM-CRF and existing Bi-LSTM-CRF models on 80% of 4,000 manually ann.. View more»
