For kidney patients who do their own dialysis at home, nurses must review information data gathered during a treatment session. “These nurses need to know quickly when there is a problem like peritonitis, which can kill a patient in a day—but not be overwhelmed with alerts and messages," says Merryl Gross, an information architect and senior UX Designer for Fresenius Medical Care North America. The company’s Web-based software for clinics and nurses who are responsible for dialysis and other services needs to be carefully crafted. It has to display information in a way that draws nurses' attention to both immediate and long-term problems, without being confusing or overwhelming.

For people interested in a UX design role, Gross says, “You can start with a subspecialty like usability testing, then add, like, information architecture or interaction design to broaden your focus." Someone with coding experience “may be able to start as a UI designer." Or, Gross says, “You could go the graphic artist route, if a company needs controls designed as part of the work. If you do technical writing, there are UI writers who do the text parts of user interfaces."
