A validated framework for developing reference plans: Evaluating global clinical trial credentialing and PSQA systems

This study presented a practical framework to develop and validate a set of reference plans and perturbations that can be used to assess and compare the differentiability of various audit and PQSA methodologies. The Global Quality Assurance of Radiation Therapy Clinical Trials Harmonization Group (GHG) has developed this framework as part of their ongoing work to test the comparability of their audit systems; this framework supports their work of aligning international dosimetry audits across the globe.

A multi-institutional approach to quantifying the differences among international dosimetry auditing methodologies

This study assessed and compared the performance of end-to-end audits currently offered by six international clinical trial dosimetry audit agencies with the goal of harmonizing audits and reducing overlap in multinational trials while maintaining quality. This effort was led by the GHG.

In general, the agreement demonstrated amongst the auditing methodologies, particularly system sensitivity to detecting errors, suggests that reciprocity of clinical trial credentialing processes could be adopted by these varied agencies. This would streamline the clinical trial process and decrease the number of barriers to clinical trial participation.
