What characterizes free text fields in the Epic system?

Free text fields in the Epic system are characterized by their ability to allow users to enter any text they wish, without being limited to predefined options. In particular, these fields often use asterisks (***), serving as a visual cue to indicate that users can input comments, notes, or other types of unstructured data. This flexibility is essential for capturing nuanced information that may not fit neatly into standardized categories.

The other options each describe different functionality within the Epic system. Identifying fields with # signs and providing listed options are indicative of structured data inputs, where users must select from a set of defined choices. Linking patient records does not specifically pertain to the nature of free text fields, as it refers to the functionality of connecting information across different records or systems rather than the mechanism of entering free-form text. Thus, the use of asterisks serves to specifically designate these versatile fields for user input.
