[Development of a Web-based laboratory data browser integrated with heterogeneous clinical information]

Area of Science:

• Medical Informatics
• Health Information Systems
• Clinical Data Management

Context:

• Hospitals manage vast amounts of patient data across disparate systems.
• Integrating laboratory results with other clinical information is challenging.
• Efficient access to comprehensive patient data is crucial for effective medical care.

Purpose:

• To demonstrate the feasibility of a web-based laboratory data browser.
• To integrate heterogeneous clinical information within a hospital setting.
• To provide a practical solution for accessing and visualizing patient data.

Summary:

• A Java-based web application was developed using open-source software.
• The system queries heterogeneous hospital databases, integrating laboratory results, prescriptions, and nursing data.
• Data is presented in a time-series table format accessible via web browsers.

Impact:

• The system demonstrated practical response times with large databases (>90 million records).
• Medical personnel adopted the system for various clinical applications.
• Simultaneous presentation of integrated medical information enhances laboratory data value and may improve medical management.
