Reducing the Risks of Home Dialysis Innovation and Uptake: The Case for Human-Centered Product Design

Advances in Human-Centered Care to Address Contemporary Unmet Needs in Chronic Dialysis

Advances in the treatment of kidney failure with chronic dialysis have stagnated over the past three decades, with over 50% of patients still managed by conventional in-hospital haemodialysis. In parallel, the demands of chronic dialysis medical care have changed and evolved due to a growing population that has higher frailty and multimorbidity. Thus, the gap between the needs of kidney failure patients and the healthcare capability to provide effective overall management has widened. To address this problem, healthcare policy has increasingly aligned towards a human-centred approach. The paradigm shift of human-centred approach places patients at the forefront of decision-making processes, ensuring that specific needs are understood and prioritised. Integration of human-centred approaches with patient care has been shown to improve satisfaction and quality of life. The aim of this narrative is to evaluate the current clinical challenges for managing kidney failure for dialysis providers; summarise current experiences and unmet needs of chronic dialysis patients; and finally emphasise how human-centred care has advanced chronic dialysis care. Specific incremental advances include implementation of renal supportive care; home-assisted dialysis; hybrid dialysis; refinements to dialysis methods; whereas emerging advances include portable and wearable dialysis devices and the potential for the integration of artificial intelligence in clinical practice.

From Home to Wearable Hemodialysis: Barriers, Progress, and Opportunities

Although the past two decades have seen substantial proportional growth of home hemodialysis in the United States, the absolute number of patients treated with home hemodialysis remains small. Currently available stationary hemodialysis devices for use in the home have inherent limitations that represent barriers for more widespread adoption by a larger proportion of individuals with kidney failure. These limitations include device weight and bulk, ergonomics considerations, technical complexity, vascular access challenges, and limited remote patient monitoring. Recent years have witnessed a resurgence in research and development of prototype wearable kidney replacement devices incorporating innovations in miniaturization, new biomaterials, and new methods for toxin clearance and dialysate regeneration. Recent work has built on five decades of incremental innovation in wearable dialysis concepts and prototypes, starting from the work by Kolff in the 1970s. Wearable dialysis devices that successfully overcome key persistent barriers to successful development and adoption of these technologies will radically reshape the landscape of kidney replacement therapies and have the potential to dramatically improve the lives of individuals living with kidney failure.
