Aresearcher conducts a focus group to learn about attitudes towards hygiene and disease prevention. two weeks after the focus group, the researcher learns one of the subjects had a heart attack at home and was hospitalized, but made a full recovery. based on dhs regulations, the researcher report this event to the irb?

IRB stands for Institutional Review Board which is establish to protect the welfare of people who are participating in human researches.

In this case, a research is conducted focusing on hygiene and prevention, but two weeks later a subject had a heart attack. So, in this scenario, the researcher doesn't have to report this event to the IRB, because the research is not related with this type of disease, it's only about prevention, and there's no way that any event could help to have a heart attack.

Therefore, the report is not needed, because what happened is due to other variables outside the research.
