A multicenter descriptive analysis of anemia management in hemodialysis patients and its association with quality of life

Abstract

Background Appropriate management of anemia in patients with hemodialysis (HD) involves the administration of iron supplementation and erythropoietin-stimulating agents (ESAs), in addition to monitoring the response. This study aimed to evaluate the treatment of anemia in patients with HD and describe the factors associated with it and its effect on health-related quality of life (HRQOL). Methods The study was cross-sectional in design. The patients were included from three dialysis centers in Palestine from June to September 2018. The data collection instrument consisted of two portions; the initial portion contained demographic and clinical information on the patients, while the second consisted of the European Quality of Life 5-Dimension Scale (EQ-5D-5 L) and the visual analog scale EQ (EQ-VAS). Results The study included 226 patients. Their mean age (± SD) was 57 ± 13.9 years. The mean level of hemoglobin (Hb) (± SD) was 10.63 ± 1.71 g/dl, and 34.1% of the patients had a Hb level of 10-11.5 g/dl. All patients who required iron supplementation received it intravenously with a dose of 100 mg of iron sucrose. Almost 86.7% of the patients received darbepoetin alfa intravenously at 0.45 mcg/kg a week, and 24% had a Hb level > 11.5 g/dl. There were significant associations between the level of Hb and the number of comorbid diseases and the ESA that was received. However, other demographics and clinical factors did not significantly affect Hb levels. Certain variables, such as exercise, were a predictor of a higher quality of life. It should be noted that there is a significant impact of a low Hb value on the EQ-VAS scale. Conclusions Our study found that more than half of the patients had a Hb level below the recommended goal of Kidney Disease Improving Global Outcomes (KDIGO). Furthermore, a significant association was found between patients’ Hb level and HRQOL. Therefore, the appropriate treatment of anemia in patients with HD should be followed by adherence to the guideline recommendations, which consequently improves the HRQOL of HD patients, in addition to obtaining optimal therapy.
