What must a researcher do promptly after an unexpected theft of identifiable study data?

After an unexpected theft of identifiable study data, it is crucial for a researcher to report the incident to the Institutional Review Board (IRB) promptly. The IRB is responsible for overseeing the ethical aspects of the research, including the protection of participants' rights and privacy. By reporting the theft, the researcher allows the IRB to assess the situation, evaluate the risks to the participants, and determine whether further action is necessary to mitigate harm and ensure compliance with ethical guidelines.

This process also helps in maintaining the integrity of the research and establishing transparency regarding any adverse events that could compromise participant confidentiality. The IRB may recommend additional measures, such as notifying participants or altering the research methodology to enhance data security, as part of their oversight responsibilities. Thus, timely reporting to the IRB is essential to uphold ethical research practices and protect participant welfare in the aftermath of such an incident.
