Health-related quality of life and associated factors in patients undergoing kidney replacement therapies.

Abstract

Objective: Characterize the health-related quality of life among patients undergoing kidney replacement therapy and to explore associated factors.

Method: A descriptive observational study was conducted using the Kidney Disease Quality of Life Short Form (KDQOL-SF) questionnaire to assess health-related quality of life. The Dader Method was employed to evaluate negative outcomes associated with medications. Face-to-face interviews and clinical records were utilized to collect sociodemographic and clinical data from patients undergoing kidney replacement therapy at the Nephrology Department of Virgen de las Nieves University Hospital (Granada, Spain). We explored the association between independent variables (clinical and demographic factors) and dependent variables (Mental Component Score and Physical Component Score) using the lineal regression method.

Results: Ninety-one participants were included, 47 (48.35%) were females. The mean age was 62 years, 52 patients (57.14%) were on hemodialysis, 13 patients (14.29%) on peritoneal dialysis, and 26 patients (28.57%) on other forms of kidney replacement therapy. The study revealed a mean Physical Component Score of 40.89 and a Mental Component Score of 47.19. Additionally, 98.90% of the patients experienced negative outcomes associated with medications. Influential factors include age, comorbid conditions, the number of medications, and clinical parameters such as vitamin D and calcium levels.

Conclusions: This study underscores significant findings in patients undergoing kidney replacement therapy, indicating low Mental Component Score and Physical Component Score, accompanied by negative outcomes associated with medications.
