Patient selection when resources are limited
More than 50 years ago, outpatient care for patients with end-stage renal disease (ESRD) became possible through the invention of the Scribner shunt. Since that time, renal replacement therapy (RRT) has expanded to include haemodialysis, peritoneal dialysis, and renal transplantation. There has been tremendous global growth in the number of patients with access to RRT for ESRD, but many societies face difficult triage decisions for these costly modalities similar to those faced by the pioneers of outpatient dialysis in the early 1960s. Developed and developing societies will face the complex challenges of addressing the costly needs of an ESRD population that is projected to rise rapidly secondary to population ageing, as well as the increased burden of chronic diseases such as diabetes mellitus and hypertension. The history of outpatient RRT is outlined and trends in RRT growth throughout the world noted. The ethical considerations with which both developed and developing societies will have to contend to address the growing global burden of ESRD are discussed.
