What is it? Why is it important?

Quality Management includes a set of activities, processes, and implemented measures that ensure that study data is of high-quality.

Data quality:

  • Is within the responsibility of the SP-INV who must guarantee the quality of all collected study data (variables)
  • Depends on whether data was correctly documented, collected, handled and analysed. As a consequence, data handling processes and guidelines should be in place
  • Is important because it grants confidence that given study results are reliable and credible

When implementing data quality measures, a risk-based approach should be used.

More

A risk-based approach includes to:

  • Identify potential risks to data quality (e.g. documentation errors, data input errors, incompatible software updates, untrained staff responsible for data input)
  • Evaluate risks and their likelihood of occurrence, ability to be detected and expected impact on data quality
  • Based on risk evaluation prioritise risks and define risk control measures
  • Plan periodic risk reviews during study conduct so as to
    • Evaluate the ongoing efficiency of any implemented mitigating measures
    • Identify new risks

What do I need to do?

Means to ensure data quality include:

  • The identification of potential risks that might negatively affect your data, including strategies able to mitigate these risks
  • The introduction of respective processes and supporting documents (e.g. SOPs, WIs, checklists)
  • Establish responsibilities and train study staff on data handling procedures, mitigating measures and its ongoing effectiveness during study conduct
  • Means to personalise CDMS setup in order to support ongoig data quality
  • Monitor correct data collection, processing and handling procedures. Plan a risk-based monitoring strategy applicable to the study
  • As required perform system validation and functionality testing
  • Ensure ongoing system maintenance and security, including ongoing data backup and recovery due to system failure
  • Applicable archiving procedures

For more information refer to Quality and Risk and Monitoring in this Trial Guide.
