Adverse Event Reporting

What Is an Adverse Event

An adverse event is any undue or unplanned harm to a research participant. There are several types of adverse events that can be reported:

  • An event that in the opinion of the principal investigator (1) was unexpected and (2) was related to
    the research procedures;
  • An event that requires prompt reporting according to the research sponsor (if any);  
  • An accidental or unintentional change to the IRB approved protocol that involves risks or has the
    potential to recur;
  • A deviation from the protocol without prior IRB approval to eliminate any apparent immediate
    hazard to a research participant;
  • A publication in the literature, safety monitoring report, interim result, or other finding that indicates
    an unexpected change to the risk/benefit ratio of the research;
  • A breach in privacy/confidentiality/data security/loss of study data that may involve risk to
  • A complaint of a participant that indicates an unanticipated risk or cannot be resolved by
    the research staff.
