AB  - Background: De-identification is a technique that eliminates identifying
information from Clinical Records in order to protect individual privacy.
This procedure decreases the chance of personal information being collected,
processed, distributed, and published from being used to identify
the person. When Machine Learning techniques were included in
the de-identification process, it substantially improved over the previous
method.
Research Problem: The Electronic Discharge Summary(EDS) has evolved
into a significantly improved technique of providing discharge summaries
though this information contains Protected Health Information
(PHI), which poses a risk to patients’ privacy. This makes the process of
de-identification to be mandatory. There have lately been several Machine
Learning approaches to de-identify data. This study focuses on
applying Machine Learning techniques to figure out which model can
best de-identify a data set.
Methods: The open source data set from Harvard Medical School was
used. This data set contains 899 Electronic Health Records (EHR), 669
for training and 220 for test purpose. The Conditional Random Fields
(CRF), Long Short Term Memory (LSTM) and Random Forest models
were used, and the performance of each model was assessed.
Findings: In order to assess each model’s performance, evaluation metrics
were used to compare F-measure, Recall and Precision at token level
to determine which Machine Learning model performed best. The Long
Short Term Memory was found to outperform both Conditional Random
Fields and Random Forest with micro average F-measure, Recall
and precision of 99%, and macro average F-measure of 77%, Recall of
73% and Precision of 90%.&#xd;
