Anemia is common in chronic kidney disease (CKD), and suboptimal management of anemia can lead to serious health complications and poor quality of life.
1) To describe health-related and overall quality of life among patients entering a clinic focused on anemia management; 2) to compare their baseline quality of life with other relevant populations; 3) to explore predictors of quality of life prior to anemia management; and 4) to explore changes in quality of life over 1 year for patients managed in the clinic.
The Kidney Disease Quality of Life questionnaire – short form (KDQOL™-SF) was used to measure kidney disease specific and overall quality of life in a cohort of pre-dialysis CKD patients (n=79) enrolled in the clinic from January 2003 to September 2004. Baseline measures were compared to previously published measurements. The influence of demographic and clinical characteristics on baseline quality of life was explored. Changes in quality of life were evaluated over time.
Patients with CKD entering the clinic had lower overall quality of life compared with estimates from the general US population (physical composite 35.7 vs. 48.4 and mental composite 46.0 vs. 50.2, respectively). Clinic patients had better kidney disease specific scores than patients with end stage kidney disease. General quality of life scores were similar regardless of kidney disease severity, with the exception of physical functioning which was lowest for patients with end-stage disease. Hemoglobin was the only factor predictive of quality of life. Over time, quality of life improved among patients managed in the CKD clinic, with statistically significant improvements in sleep (change of 6.2 ± 15.2; p < 0.05) and social function (change of 11.6 ± 27.7; p < 0.05).
Patients with anemia of chronic kidney disease reported reduced quality of life compared to populations without kidney disease, but better quality of life compared to populations with end stage kidney disease on dialysis. Quality of life generally improved among patients managed in the multidisciplinary anemia clinic.
