What must be reviewed by the IRB/IEC regarding payments to research subjects?

The review of the amount and method of payment by the Institutional Review Board (IRB) or Independent Ethics Committee (IEC) is crucial for ensuring ethical standards in research involving human subjects. This review focuses on protecting subjects from undue influence or coercion, which can occur if payments are deemed excessive or if the payment method is not transparent. The IRB/IEC assesses whether the compensation is appropriate based on the nature of the research, the time commitment required from participants, and any potential risks associated with the study. Adequate consideration of these factors helps to maintain the dignity and welfare of research subjects while ensuring that their participation is voluntary and informed.

In contrast, while the type of treatment provided, the subjects' health care status, and the purpose of the research are all important considerations in the ethical review process, they do not specifically pertain to the review of payments to research subjects.
