What is it? Why is it important?

The quality of a study can be verified based on written verifiable records of performed study activities. Thanks to these records, the study can be retraced confirming the quality of the study. High quality studies provide confidence in the obtained study results (e.g. accurate and non-biased interpretation and reporting of study results).

 

Verifiable quality records include:

  • Essential documents: are the operational documents of the study and provide written evidence that:
  • Study specific documents: are documents that facilitate and standardise study tasks to ensure these are harmonised, (e.g. guidelines, checklists, memos)
  • Supporting ducuments: are documents that ensure the quality of work processes. They are also used outside the study (e.g. local directives such as emergency processes by freezer failure)

Essential documents:

  • Are defined in chapter 8 of ICH GCP
  • Are filed in the TMF/ISF of the study

 

Requirement and extent of collected quality records depend on identified risks, their prioritisation and risk control-measures, including study type (ClinO, HRO) and risk category (A, B, C).

What do I need to do?

As a SP-INV:

  • Define and make a list of quality documents applicable to your study. Include Quality Assurance and Quality Control aspects (e.g. develop applicable SOPs and WIs defining quality processes)
  • Finalise the essential documents required for your study  (e.g. study protocol, ICF, CRF, contracts, budget, insurance). Essential documents are submitted to EC and if applicable RA (e.g. Swissmedic) for approval
  • Start to prepare study specific supporting quality documents (e.g. useful checklists showing work flow)
  • Include study team members as potential reviewers of quality documents (e.g. is implementable, is understandable)
  • Train study staff on the implementation of quality documents

 

Site-INV responsibilities:

  • Implement quality documents provided by the SP-INV of the study
  • If needed, define and write local SOPs, WIs, and checklists to be approved by the SP-INV.
  • Ensure that the filing of essential documents are complete, up-to-date, and if applicable signed and dated (e.g. in the ISF)
  • Ensure quality documents are trained and ready to be implemented by study staff

In order to retrace study activities, essential documents are:

  • Reviewed by operational staff
  • Reviewed for accuracy and completeness by the study monitor during monitoring visits
  • Inspected by RA (e. g. Swissmedic) during study inspections in order to evaluate compliance with the study protocol, the safe conduct of the study such as safety reporting procedures, data collection and the quality of obtained data
  • Archived upon study termination for a defined period of time, depending on type of study, regulatory and local requirements
