What is it? Why is it important?

Risk evaluation asks, what is the:

  • Likelihood or frequency that a risk or error can occur?
  • Extent and ability to which an error can be detected?
  • Expected impact of an error on participant safety and quality of study results?

Risk prioritisation asks:

  • Based on risk evaluation, how should a risk be prioritised - high-, medium-, low- risk to the study?
  • How will risk-priority affect the requirement of preventative measures?

Based on these criteria the SP-INV is responsible to assess these questions in relation to the study. Thus, risks can subsequently be categorised according to high, medium or low risk.

What do I need to do?

Assess and rank potential risks:

  • In your daily practice, consider the complexity of individual tasks
  • Look for the frequency that an error could occur
  • Estimate its impact on your work, your patients, your institution, your career

Apply the same principles to evaluate potential risks in your study. Use the REM to assess risks. Based on risk category, priorities can be set for the implementation of measures needed to mitigate risks.
