Research and development
Text mining educational material for internal medicine
with Lyndi Schwartz, MD
• Kettering Medical Center
A scoping review is being performed to determine what
declarative core knowledge—that which is required for clinical
competency—in general internal medicine is also amenable to semiautomated
extraction from published biomedical literature.
The results of the review then will be used to train a
machine-learning model, in an attempt to
semiautomatically generate useful didactic educational material such as
review questions from the corpus of open-access literature.
A spaced-repetition study application for
continuous medical education is currently being
Proposal for new “smart pipes” operator for the
ECMA Technical Committee 39. The
smart-pipes proposal is published on GitHub.
Practice guidelines of BPSD pharmacologic management: a review
with George T. Grossberg, MD
• SLU SOM Department of Neurology & Psychiatry
A systematic literature review was performed over
recently published practice guidelines on the pharmacologic management of
behavioral and psychiatric symptoms of dementia.
Patient-data displays: visual presentation and design
with David Burroughs, PhD
• SLU Center for Outcomes Research
This project compiled existing information on the
visual design of patient-data displays. Information
included methods of presentation and visualization of patient data to
healthcare providers and how these methods affect
clinical decision making, diagnosis, medical errors, and medical
Meaningful-use standards for pediatric electronic health record systems
with Feliciano B. Yu, Jr., MD
• Washington University in St. Louis • St. Louis Children’s Hospital
This project consolidated several standards of meaningful-use requirements
for electronic medical records’ user interfaces into a single database. It
focused on requirements from the
Children’s EHR Format, HL7, and NIST 7865 standards.
Patient electronic-health-record programmatic data analysis
with Allan Wachter, MD
Data analysis was performed on
longitudinal patient data on behalf of A. Wachter in an
retrospective study for predicting asthma with the United
States Navy. A computer program was developed to
clean, normalize, and combine heterogenous patient data
from several independent sources: the US Navy, the US Department of
Veterans Affairs, and several pharmaceutical companies.
Clojure computer-programming library used by other developers to parse
text into data structures using grammars that the programmer creates.
FnParse was published on GitHub.
