Objectives:

The aim of this study was to analyse the Health-Related Quality of Life in patients with Advanced Chronic Kidney Disease in pre-dialysis and the relationship with renal clearance.

Material and Method:

We studied 124 patients with ACKD in pre-dialysis and age of 67.2±14.3 years (56 women, 45%). A descriptive and cross-sectional study was carried out in the Nephrology Service of the Reina Sofía Hospital in Cordoba. The KDQOL-SF questionnaire was used to analyse the Health-Related Quality of Life. The renal clearance and associated comorbidity were also analysed.

Results:

In the KDQOL, the most affected dimensions were: work situation, burden of kidney disease and sleep. Women presented worse score in list of symptoms / problems. In the dimensions of SF-36, General health, Vitality, Physical function and Physical role were the most affected. Women rated worse scores, significantly, in: General health, Vitality, Physical role, Pain and Emotional role.

Patients with lower renal clearance presented worse scores in Effects of kidney disease, burden of kidney disease and sexual function; and in Physical Role and General Health.

Conclusion:

Patients in pre-dialysis have reduced their Health-Related Quality of Life in dimensions Burden of kidney disease, Sleep, General health, Vitality, Physical function and Physical role. Renal clearance, although directly influence the symptoms derived from kidney disease, does not seem to be so decisive in quality of life, being the female sex, age and associated comorbidity, the variables most associated with poorer quality of life.
