In evaluating outcomes in end-stage renal disease (ESRD), quality of life has become as important as morbidity and mortality. Various instruments are available to analyse patients' perceptions of the physical, psychological and social domains of health. Non-specific instruments, such as the Sickness Impact Profile, the Karnofsky Scale, and the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), have been widely used in evaluating quality of life in various chronic diseases including ESRD. The Kidney Disease Quality of Life (KDQOL) questionnaire and other scales have also have been developed specifically for ESRD patients. Several studies have demonstrated a significant improvement in quality of life after initiation of epoetin treatment in both dialysis patients and those with early renal failure. Quality-of-life scores show a strong positive correlation with haemoglobin concentration. Other factors associated with better quality of life are higher socioeconomic level and level of education. However, older age, comorbidity, diabetes, female sex, and unemployment have a negative influence on quality of life. In patients not yet on dialysis, quality of life deteriorates as the glomerular filtration rate decreases. The later the patient is referred to a nephrologist, the worse the quality of life. Recent studies show that quality of life is a prognostic factor for survival. Early and effective treatment of anaemia in ESRD patients is essential in maintaining quality of life both before and after initiation of dialysis.
