Outcomes research in dialysis.

ABSTRACT

Worldwide, the number of patients with end stage renal disease (ESRD) and the number of ESRD patients receiving renal replacement therapy is growing. In the United States the number of patients enrolled in the Medicare-funded ESRD program has grown substantially, from approximately 10000 beneficiaries in 1973 to 340261 as of December 31, 1999. United States has the highest incidence ESRD of 317 per million population. Despite the magnitude of resources committed to the treatment of ESRD and the substantial improvements in the quality of dialysis therapy, these patients continue to experience significant mortality and morbidity, and reduced quality of life. Moreover, 50% of dialysis patients have 3 or more comorbid conditions, the mean number of hospital days per year is approximately 14 per patient, and self reported quality of life is far lower in dialysis patients than in general population. The most desirable interventions are those that specifically target measurable global outcomes such as mortality, morbidity, and health care costs. Nevertheless, patient outcomes that have shown links with these global outcomes may also be appropriate targets for intervention. This article will briefly review the available literature to discuss the role of important clinical indicators on dialysis outcomes and their impact on continuing care of ESRD population.
