Registry Criteria

  • Does the Registry accept prospective registration of interventional clinical trials submitted by Responsible Registrants?

  • Does the Registry have documented Standard Operating Procedures (SOPs)?

    • Are mechanisms in place to ensure compliance with these SOPs? (eg staff training)

    • Description of the compliance mechanisms:
      Staff undergo initial training in the submission and query processes. Regular audits are conducted to assess data completeness, data accuracy and data processing timeliness. SOPs are reviewed at monthly staff meetings (or more frequently if required) and assessed annually by the ANZCTR Manager. Staff are given time to attend staff development activities such as journal club and internal / external training courses that will increase their understanding of trial registration principles and procedures.

  • Can the Registry collect and publicly display the WHO Trial Registration Data Set (TRDS)?

    • What quality control measures does your Registry have in place to make sure that all 20 items in the WHO TRDS are as complete and accurate as possible?
      Once a trial is submitted for registration, the ANZCTR staff assess it within 2 working days for completeness (i.e. all mandatory fields are completed), meaningful data and general accuracy and logic. There are additional automated logic checks on certain key fields. If any queries are identified, the ANZCTR staff email these to the registrant and include suggested changes. The Registrant must make these changes on-line and then ‘re-submit’ the trial. The ANZCTR staff again check the re-submitted data and only once all criteria are satisfactorily completed is the trial registered, assigned an ANZCTR (ACTRN) number and made available for public view.
