Which of the following examples do not require institutional review board (IRB) approval?

The choice of an evidence-based project as not requiring institutional review board (IRB) approval is accurate because these types of projects often involve the application of existing knowledge and methods to improve practice, rather than generating new knowledge through research. Evidence-based projects typically utilize already collected data or do not involve interactions with human subjects that require ethical oversight to ensure their safety and rights.

In many cases, evidence-based practice involves the implementation of established guidelines, best practices, or quality improvement initiatives, which may not meet the stringent definitions of research necessitating IRB review. Conversely, randomized control trials, clinical trials involving medications, and qualitative research involving interviews often involve the collection of new data from human participants or may impact their health and well-being. These scenarios present ethical considerations that IRBs are specifically designed to address, ensuring that all research involving human subjects is conducted ethically and responsibly.
