How is an unanticipated problem defined according to the criteria established by OHRP?

An unanticipated problem is defined as an incident that is unexpected and may be related to the research being conducted, which poses greater risks to the subjects involved than those originally identified in the study protocol. This definition is significant because it acknowledges that the risks of research may evolve as new information or events arise during the study. When researchers or IRBs (Institutional Review Boards) evaluate the occurrence of such problems, they must consider whether the incident could reasonably have been anticipated based on the current understanding of the study and its potential impacts on participants.

The emphasis on both the unexpected nature and the potential relationship to the study is crucial, as it highlights the need for ongoing risk assessment and monitoring. This allows researchers to protect participants more effectively and to make any necessary adjustments to the study protocols or consent processes in light of new information.

Understanding this concept is vital for researchers to maintain ethical standards and ensure the safety and well-being of participants throughout the research process.
