Human factors and ergonomics (HFE) is the scientific discipline concerned with the understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, data, and methods to optimize human well-being and overall system performance. It is a combination of numerous fields including engineering, psychology, industrial design, biomechanics, and user interface design, among others. HFE aims to reduce human error, increase productivity, enhance safety, and improve comfort. Given that HFE covers a wide breadth of topics, this narrative review provides an overview, focusing on topics that most directly impact performance during image-guided procedures, such as information processing, situation awareness, and Fitts' law. The overall intent is to introduce the reader to strategies that might not only improve patient care but also increase the safety and productivity of the entire interventional radiology team.
