Variation in end-stage renal disease patient outcomes: what we know, what should we know, and how do we find it out?

Abstract

The size and expense of the ESRD program exceed all predictions made when the program was first initiated. Although the effectiveness of dialytic therapy is unquestioned, its value (quality/cost) is actively debated in this era of constricting resources. To better evaluate the quality of the ESRD program, it is essential to first define and quantitate the outcomes of dialytic care. Although mortality is a convenient outcome measure, it may be affected by many patient-specific as well as other factors that must be considered when evaluating and comparing new and existing technologies or advances. Quality of life is only beginning to be used in depth as an outcome measure, and much work is needed to standardize research methodology and thus move this area forward. The following review describes the current state of knowledge regarding outcomes of ESRD patients and proposes areas for future investigation, which should help increase the understanding of the value of the ESRD program to patients, providers, and payors.
