To explore the key elements in the evaluation and selection of sites for multicenter clinical trials, providing references for standardizing clinical trial site selection practices.
By integrating the practical experience of multiple sponsors, contract research organizations (CROs), and research sites, a standardized framework for site evaluation and selection was constructed.
A three-phase standardized process was proposed, encompassing pre-assessment preparation, formal evaluation, and outcome assessment. This study systematically categorized common and specific evaluation criteria, including 5 core dimensions and 17 key indicators covering site and personnel qualifications, hardware conditions, patient resources and quality systems, management processes, and special considerations.
This study constructed a comprehensive site evaluation system encompassing standardized procedures, structured dimensions, and core indicators. It achieves a transformation in evaluation practices from an experience-driven approach to a framework-guided methodology, providing an operable tool for the scientific selection of sites in multicenter clinical trials.
