Assessment of health-related quality of life and its determinants in the pre-dialysis patients with chronic kidney disease

Abstract

Health-related quality of life (HRQoL) is increasingly being considered as a critical parameter to measure how the disease affects patients’ health status, especially for long-term ailments like chronic kidney disease (CKD). This study aimed to assess the HRQoL and its determinants in pre-dialysis patients with CKD. This cross-sectional study recruited patients with CKD stages one to four. Data were collected using the HRQoL Questionnaire (15D). Descriptive statistics were used to summarize patients’ characteristics. Chi-square test or Fisher’s exact test was used to explore the association between independent variables and the HRQoL. Multivariate logistic regression analyses were employed to investigate the determinants of HRQoL. A P value of less than 0.05 was considered statistically significant. Two hundred and twenty patients were enrolled in the study (average age 52.7\u2009±\u200912.4 years, 61.8% females, and 69.1% with CKD stage 4). The average multidimensional utility score of the study population was 0.82\u2009±\u20090.13, while the single-attribute utility scores ranged from 0.73 to 0.89. The speech, and discomfort and symptoms dimensions had the highest (0.89) and lowest (0.73) single-attribute utility scores, respectively. The patients who were uneducated [Adjusted Odds Ratio (AOR) 0.34, 95% CI (0.12–0.97)] were significantly less likely to have poor HRQoL compared to those with tertiary education level. Additionally, unemployed [AOR 4.69, 95% CI (1.69–13.02)], and self-employed patients [AOR 4.25, 95% CI (1.26–14.38)] were significantly more likely to have poor HRQoL compared to the retirees This study shows that the overall HRQoL of the participants was high, though a considerable proportion of them had poor HRQoL, while the discomfort and symptoms dimension was the most impacted. Being educated, unemployed, and self-employed were significantly and independently associated with poor overall HRQoL.
