We developed a Java-based web system for collecting data in multi-centre clinical trials. This internet system offers advantages over traditional methods and addresses security concerns for online data collection.

Area of Science:

  • Computer Science
  • Medical Informatics
  • Software Engineering

Background:

  • Multi-centre controlled clinical trials face significant data collection challenges.
  • Current methods for internet-based data collection often rely on less efficient technologies like HTML/CGI.
  • Secure and reliable data management is crucial for clinical trial integrity.

Purpose of the Study:

  • To describe a novel web-based documentation system for multi-centre clinical trial data collection.
  • To highlight the advantages of a Java-based system over traditional internet data collection approaches.
  • To explore potential extensions and security considerations for internet-based clinical trial data management.

Main Methods:

  • Development of a platform-independent Java applet for the client-side.

  • Implementation of a three-tier architecture with a central server for the database and application logic.
  • Utilizing Java applications for handling and monitoring client requests via the application server.

    • Main Results:

    • The developed system provides a centralized and accessible platform for data collection across multiple centres.
    • The Java-based system demonstrates superior performance and flexibility compared to HTML/CGI combinations.
    • The system architecture allows for potential integration with external resources like data dictionaries.

    Conclusions:

    • A Java-based web system offers an effective solution for multi-centre clinical trial data collection.
    • The three-tier architecture enhances data management efficiency and accessibility.
    • Addressing internet security is paramount for the successful implementation of such systems in clinical research.
