Introduction
Health status and health-related quality of life (HRQoL) are core components of health outcomes. HRQoL measures can be assessed with both generic and disease-specific instruments [1]. Renal replacement therapy (RRT) is a life-saving treatment for patients with end-stage renal disease. The two main treatment modalities are transplantation and dialysis (i.e., hemodialysis [HD] or peritoneal dialysis [PD]) [2] and [3]. Because of an increase in survival rates for patients with end-stage renal disease, HRQoL has become increasingly important as an outcome measure in the evaluation of dialysis treatments. [4] It has also been suggested that for patients receiving RRT, quality of life measures can be used to predict future morbidity and mortality [5]. Studies examining the difference in quality of life outcomes associated with HD and PD have mixed results [4] and [5].
