An automated patient registration and treatment randomization system

Area of Science:

• Clinical Trials Methodology
• Health Informatics
• Biostatistics

Background:

• Centralized systems offer advantages for multicenter clinical trials compared to decentralized approaches.
• Ensuring data integrity and security is paramount in clinical trial management.
• Automated systems can improve efficiency and accessibility in trial processes.

Purpose of the Study:

• To introduce a fully automated system for patient registration and treatment randomization in multicenter clinical trials.
• To highlight the security features and data validation techniques employed.
• To present the implementation of diverse randomization methods to accommodate various study designs.

Main Methods:

• Development of an Interactive Voice Response (IVR) microcomputer-based application for unattended operation.
• Implementation of security measures to protect system access and data.
• Integration of data validation and accuracy checks.
• Inclusion of multiple randomization algorithms: balanced block, stratified permuted block, minimization, and Zelen's adaptive randomization.

Main Results:

• The system provides continuous availability for patient registration and randomization.
• Robust security and data accuracy measures are integrated.
• Flexible randomization options support complex clinical trial designs, including those requiring institution balancing.

Conclusions:

• Automated centralized systems, like the one described, enhance the efficiency, security, and accuracy of multicenter clinical trials.
• The system's adaptability through various randomization methods supports a wide range of research protocols.
• Continuous availability and unattended operation improve trial management logistics.
