Appropriateness of anemia management in hemodialysis patients

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

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.

Prevalence and management of anemia in pre-dialysis Malaysian patients: A hospital-based study

Objective:

Anemia, a common complication of chronic kidney diseases (CKD), is involved in significant cardiovascular morbidity. Therefore, the objective of our study was to investigate the prevalence and severity of anemia in pre-dialysis patients, as well as to determine the predictors of anti-anemic therapy.

Method:

A retrospective, observational study was conducted on adult pre-dialysis patients receiving treatment at the Hospital Universiti Sains Malaysia from January 2009 to December 2013.

Results:

A total of 615 eligible cases were included. The mean age of patients was 64.1±12.0 years. The prevalence of anemia was 75.8%, and the severity of anemia was mild in 47.7% of the patients, moderate in 32.2%, and severe in 20%. Based on morphological classification of anemia, 76.9% of our patients had normochromic-normocytic anemia whereas 21.8 and 1.3% had hypochromic-microcytic anemia and macrocytic anemia, respectively. Oral iron supplements were prescribed to 38.0% of the patients and none of the patients was given erythropoietin stabilizing agents (ESA) or intravenous iron preparations. In logistic regression, significant predictors of anti-anemic preparation use were decreased hemoglobin and hematocrit, and advanced stages of CKD.

Conclusion:

The results of the present study suggest that the prevalence of anemia in pre-dialysis patients is higher than currently accepted and it is found to be correlated with renal function; prevalence increases with declined renal function. An earlier identification as well as appropriate management of anemia will not only have a positive impact on quality of life but also reduce hospitalizations of CKD patients due to cardiovascular events.
