QA Policy, Guidelines and Credentialing

QA Policy, Guidelines and Credentialing

TROG QA Policy 

The Quality Assurance in TROG Clinical Trials policy outlines the procedures adopted by TROG to ensure world-class excellence in the design and management of radiation therapy and imaging QA in TROG Clinical Trials. 

TROG also has a number of guidelines relevant to clinical trials and technical frameworks as resources for trial chairs to  help develop clinical trial protocols and programs.

Additional guidelines available via our Member Portal include: 

  • TROG Dose to water/medium specifications in TROG clinical trials

  • Currency of technical audits for TROG trial participation

  • Medical Image Registration in TROG clinical trials

  • TROG Flattening Filter Free Position Statement

  • Policy for Independent Audits

Credentialing and On-Trial QA

Credentialing, in the context of radiation therapy and imaging QA, is the process of obtaining, verifying and analysing centres that conduct TROG Cancer Research clinical trials, to ensure minimum requirements and standards are met. Credentialing is performed on a trial-by-trial basis, depending on the risk management assessment. 

TROG’s On-Trial QA typically involves submission of participant data for the purposes of individual case review (ICR) or data collection. 

 ICR programs are implemented according to the level of risk identified, taking into account the trial question, technologies, techniques and centre experience.  They include pre-treatment reviews, timely reviews, post-treatment reviews and imaging timepoint reviews.

More information about our Credentialing processes and On-Trial QA is available on our member portal.

[Credentialing] ensures that all participating centres are able to treat patients to a standard that will not impact on the ability of the trial to answer the study question.
