2. Objective
• To leverage EMRs to enhance patient care.
• To realize a system that will analyze a patient’s
evolving EMR:
• in context with all available biomedical knowledge.
• using the accumulated experience recorded in the EMRs of other
patients.
• with the help of interactive, automated, actionable text mining
tools.
• using multidisciplinary approach. Computer

3. Flow Chart of the CDS Dashboard
The CDS Dashboard, in a secure network, will help physicians find de-identified
electronic medical records similar to their patient's medical record, relevant
medical literature, recent research findings, and clinical trials thereby aiding
them in diagnosis, treatment, prognosis and outcomes.

4. Challenges
Several challenges exist in creating a CDS Dashboard that can be universally used
including:
Variation in entries in the EMRs; each doctor uses their own set of acronyms and shortcuts.
The presence of billing and CPT codes.
Combinations of unstructured and structured laboratory data.
Presence of lexical variants and synonyms.
5. Goals
Our goal in building the CDS Dashboard was the ensure :
platform
portability
independence
can layer on
top of existing
electronic
modularity

Discussion
• The tool can be used in multiple ways:
• Teaching aid for medical students
• Exploratory tool for doctors and nurses
