Background
Compared to traditional in-centre hemodialysis, home hemodialysis (HHD) is a more cost-effective option, offering patients more autonomy, better quality of life, and improved health outcomes. However, uptake rates of HHD are the lowest among all other modality types. Therefore, there is a need to develop efficient HHD systems that are user-friendly and appealing to patients. The SC+ Hemodialysis System developed by Quanta Dialysis Technologies for home and clinic use, provides patients with a compact, safe, and easy-to-use HHD system that minimizes the burden of traditional dialysis treatments, whilst providing equivalent dialysis adequacy.
Methods
As part of the design validation of the SC+, Human Factors Testing (HFT) was performed with 15 Home Users (patients and caregivers) and 17 Healthcare Professionals (nephrology nurses and healthcare assistants), to assess safety, performance, and ease of usability. The HFT involved a training session with each participant at Smethwick Dialysis Centre in Birmingham, United Kingdom, which was subsequently followed by a test session where participants independently performed 38 subtasks on the SC+. A detailed study protocol was used to critically evaluate each participant in a standardized manner.
Results
In aggregate, 1,171 from the 1,216 subtasks attempted between the two user groups were completed successfully. Overall, the Healthcare Professionals performed with a higher degree of use safety, with a task-specific success rate of 97.4%, compared to 95.1% in the Home Users (patient and caregiver) group. Healthcare Professionals encountered use errors in 0.9% of sub-tasks attempted. In contrast, 0.2% of subtasks attempted by home users resulted in a close call (they initially encountered a use error, but were able to self-correct), and 3.9% resulted in use errors. Due to circumstances unrelated to the study itself, 1.7% of subtasks attempted by healthcare professionals, and 0.9% by home users, were unperformed. No errors resulted in adverse events.
Conclusion
The SC+ Hemodialysis System was found to have minimal issues related to ease of usability by patients, caregivers, and healthcare professionals. The data from this usability study indicates that in the real world, a high degree of use safety will likely be achieved, resulting in an optimal user experience.
