Creating an environment for linking knowledge-based systems to a clinical database: a suite of tools

Area of Science:

• Medical Informatics
• Clinical Data Management
• Knowledge-Based Systems

Background:

• Linking knowledge-based systems to clinical databases presents challenges in data mapping.
• Existing systems often require extensive user knowledge of databases and vocabulary.

Purpose of the Study:

• To develop tools for seamless integration of knowledge-based systems with clinical databases.
• To enable users to retrieve clinical data without specialized database or vocabulary expertise.

Main Methods:

• A suite of tools was developed, including Query Builder, MED Browser, Clinical Database Browser, and Event Playback.
• These tools facilitate query creation, term identification, data aggregation, and query testing within the knowledge-based system environment.

Main Results:

• The developed tools allow users to easily create queries and retrieve data from clinical databases.
• Users can effectively map knowledge-based system data to clinical database information.
• The tools support data aggregation and query validation within the knowledge-based system.

Conclusions:

• The developed tool suite successfully addresses the challenge of linking knowledge-based systems to clinical databases.
• These tools enhance usability and accessibility of clinical data for a wider range of users.
• The system has been in operational use for one year, demonstrating practical application.
