Perceived health and quality of life in chronic and end-stage kidney disease

Background and objectives

Health-related quality of life (HRQoL) is increasingly considered a major outcome in patients with chronic kidney disease (CKD), but the size of its effect on physical and mental health at different disease stages, compared with the general population, is unclear.

Design, setting, participants, and measurements

We compared HRQoL measures in four groups: 2,687 outpatients with moderate (stage 3, estimated glomerular filtration rate [eGFR] 30-60 mL/min/1.73 m2) or advanced (stage 4-5, eGFR < 30 mL/min/1.73 m2) CKD under nephrology care from 40 nationally representative facilities, 1,658 patients with a functioning graft, 1,251 dialysis patients randomly selected from the national REIN registry, and 20,574 participants in the French Decennial Health Survey, representative of the general population.

Results

Mean age (years) was 67, 69, and 55 in patients with non-end-stage CKD, on dialysis, or with transplants, respectively; 60% were men. Age- and gender-standardized health status was perceived as fair or poor in 27% of those with moderate CKD and more than 40% of those with advanced CKD and those on dialysis, compared with 12% in transplant patients and 3% in the general population. Compared with the general population, HRQoL physical scores adjusted for age, gender, education, obesity, and diabetes, were significantly lower, by a factor of 2.2 among patients with moderate CKD, 4.1 among those with advanced CKD, 10.2 among those on dialysis, and 4.1 among those with transplants. The effect was stronger for those younger than 65 years. The mental score was lower only for dialysis patients.

Conclusions

This study highlights the importance of the physical health effects beginning at the moderate stage of CKD. More attention to patients’ CKD-related perceived health is needed.

Key messages

Physical health declined significantly from moderate through end-stage CKD, with impact greatest among the youngest patients. More attention to CKD’s impact on quality of life is needed.
