What is it? Why is it important?
The aim of Quality Control (QC) is to periodically review implemented procedures and processes in the study in order to ensure that:
- The study is conducted in compliance with the study protocol, study SOPs, ICH GCP, and applicable laws (e.g. Swiss law)
- Data is correctly generated, collected, handled, and analysed
QC is an integral part of Quality Assurance (QA) and includes activities and techniques used to systematically check study compliance. Non-compliance results in findings that must be addressed and resolved.
Example of QC measures
Monitoring is an important medium used by the SP-INV to evaluate compliance and perform QC checks at participating study sites.
Quality indicators include, but are not limited to:
- Patient eligibility criteria consistently respected and abided by as defined in the study protocol
- IC process correctly documented ensuring traceability
- Adherence to safety reporting timelines
- Scheduled visits and applicable procedures are followed and documented (e.g. blood draw, questionnaire, timing)
- Data entry completed within required timelines
- Study visit documented in CRF, updates entered in medical records
- Documentation on staff trainings (e.g. ICH GCP certificate, IC process, IMP/IMD handling)
- Correct handling of the investigational product (e.g. IMP/IMD access and temperature control, inventory log with traceability on dispense, return, destruction)
What do I need to do?
- eCRF automatic alerts in the event of out-of-range data entries
- 24 hours temperature surveillance of freezers storing biological material, including an efficacy check of the emergency plan process
- Ongoing study monitoring adaptions (e.g. number of total visits, extent of document and SD checks, type of monitoring visit (e.g. on-site, centralised)
- Extend of data processing checks
For more information refer to Monitoring in this Study Guide
Based on the QC strategy of your study provide applicable:
- Written SOPs and WIs: These documents give detailed guidance on how standards, processes, and given requirements should be implemented in study core activities - in daily work
- Guidance on the handling of study risks, by documenting the risk management of your study in a RAF (e.g. including quality document)
- Ensure to train staff on the QC activities of your study
