Market research and human factors study results. Percentage of respondents shown on the x-axis (a, e, f) or y-axis (b, c) and number of respondents (n) shown on the right y-axis (a, e, f) or above each response bar (b, c). (a) Seven-point Likert scale results comparing opinions from professionals and current and past patients and caretakers on worry about peritoneal dialysis (PD) (top three), and fear of peritonitis (bottom three). Professionals were asked if they feel worried about patients and if they think patients feel worried right before, during, or right after a PD session. Similarly, professionals were asked if they are afraid for their patients and if they think their patients are afraid of potential infection when they set up or do PD. (b) Professional respondents who see patients selected time bins (x-axis) for estimated duration of a five-step process from peritoneal infection to treatment. Dark to light grey bars (left to right) represent shortest to longest time options, respectively. (c) Reported recommendation for frequency of chequeing effluent from professionals who see patients versus frequency reported by current and past patients and caretakers from both studies. Dark to light grey sections (top to bottom) represent highest to lowest frequency, respectively. (d) Device setup times (s) from the human factors study for nine participants. Black circles represent three individual trial times per participant. Red “x” markers represent mean setup time among trials for each participant. Mean setup time across all trials and participants (15.6 s) shown with bottom dotted line; grey bar represents ± s.d. (5.9 s). This compares to the average PD setup time of 1050 s or 17.5 min (top dotted line). (e) Seven-point Likert scale responses from past, current, and prospective patients and caretakers on willingness to use OpticLine (top bar), how difficult they think it would be to set up OpticLine (middle bar), and for current and past patients and caretakers, the difficulty of their PD setup (bottom bar). (f) Professional respondents ranked on a five-point Likert scale for thinking the device could significantly improve PD patients’ quality of life and their own quality of life.
