Evolution of dialysis treatment graphics based on stakeholder input. The survey graphics of in-center hemodialysis, the reference treatment, and wearable RRT devices, the alternative treatment, underwent iterative stakeholder-guided revisions. Changes to the in-center hemodialysis treatment graphic included: addition of a blood line and a health care professional (B), followed by addition of a second blood line, elevation of the patients’ feet, addition of machine detail, and change in color of the blood lines from gold to red to resemble actual in-center bloodlines better (C). Changes to the wearable device graphics included: addition of a blood line, change in color of the people from black to gray, and removal of the vest-based graphic (B), followed by change in color of the people from gray to tan, conversion of the backpack style from bulky to more compact, and change in color of the blood lines from red to gold to signify the potential discreteness of the device (C).
