O'Hare AM. Dialysis adequacy reconsidered: The person comes first. Seminars in Dialysis. 2020 Nov 26; 33(6):486-489.
Although many nephrologists see value in maximizing clearance and time on dialysis, clinical trials have failed to show a clear and consistent benefit of increasing clearance above the minimum threshold level recommended in clinical practice guidelines or of increasing dialysis session length or frequency. Available evidence suggests that patients and clinicians do not necessarily agree on what matters most when it comes to dialysis care, and that what patients consider to be an adequate dialysis session is highly individual and has little to do with solute clearance. Qualitative studies suggest that patients value spending less time on dialysis, having the dialysis procedure go smoothly, and being treated like an individual by staff members. Because many patients feel that they have little choice but to show up for their dialysis sessions, failing to involve them in decisions about time spent on the machine can contribute to feelings of powerlessness and loss of control, erode their sense of self, and diminish the quality of therapeutic relationships. On the other hand, a flexible and shared approach to decision-making about time spent on dialysis (and other aspects of care) can help to strengthen relationships, uphold personhood, and align care with what matters most.
