The document introduces 3 database research projects at the Center for Women's Health Research: 1. Clinical Form Encoding seeks to standardize clinical terms on forms using clinical coding schemes like SNOMED CT. 2. EMR Error Detection aims to improve electronic medical record systems by more robustly integrating clinical guidelines to reduce data entry errors. 3. A Query and Data Extraction Tool is being developed to help researchers and providers more easily access and analyze the large amounts of patient data stored in databases.

5. Dissertation Project
Accommodate Changing User Needs
FormMapper
- Form understanding
- Equivalent elements discovery
- Birthing new database elements

6. Dissertation Project
The FormMapper Tool
 Solution:
 Novel Techniques
Evolved  Re-use Existing
Form FormMapper Database
Database
 Experiments in Healthcare
 52 clinical forms
 Objective:
 6 databases: 35-500 tables
 To evolve a high-quality database.
 84.5% match with gold
standard
 74% high-quality
Lesson Learnt
Quality of evolved databases could be improved …
… if the terms used on forms are standardized (clinically encoded)
