IRBs encounter several challenges unique to epidemiological research:
1. Data Sharing: The need for data sharing and collaboration can conflict with privacy protections. IRBs must balance these needs carefully. 2. Complex Study Designs: Epidemiological studies often involve complex designs, such as longitudinal studies or studies using secondary data, which can complicate the review process. 3. Global Research: Conducting research across different countries with varying ethical standards and regulations can pose significant challenges.
