Usability study demonstrates high task success rates for a novel automated peritoneal dialysis device in patients and nurses, indicating intuitive and safe home-based operation.
Key Points
To evaluate the usability, safety, and operational effectiveness of a novel gravity-based automated peritoneal dialysis (APD) system in intended users.
Conducted a summative human factors usability study evaluating the Archimedes™ gravity-based APD device.
Enrolled 15 current or former peritoneal dialysis patients and 15 dialysis nurses (N=30) who completed 2 hours of training followed by a training decay period.
Evaluated performance on critical Use Scenario tasks, comprising Simulated Use tasks and Knowledge tasks associated with potential patient harm.
Achieved an overall success rate of 97.3% across all Simulated Use tasks, with success rates of 96.8% in patients and 97.8% in nurses.
Achieved Knowledge task success rates of 99.3% among patients and 98.6% among dialysis nurses.
