US FDA guidelines for human factors and medical device marketing submissions

The U.S. Food and Drug Administration (FDA) issued a new draft guidance document, “Content of Human Factors Information in Medical Device Marketing Submissions,” on Dec. 9, 2022. The guidance is intended to help medical device manufacturers determine what evaluation information should be included in a marketing submission, e.g., 510(k)s, De Novo requests, PMAs, including PMA supplements, and humanitarian device exemption (HDE) applications. The guidance outlines three distinct submission categories, dependent on various factors, such as changes made to an existing device, the extent of those changes (if applicable), and the presence of critical tasks.
