Abstract
The projected future demand for renal replacement therapies for patients with end-stage renal failure requires preparedness at different levels. The deliberations focus predominantly on the disproportionately high financial burden of care for patients on routine dialysis therapy compared with other chronic conditions. However, even today there are concerns regarding the shortage of healthcare workers in the field of nephrology. A substantial increase in trained healthcare professionals is needed for the future delivery and care of patients requiring haemodialysis (HD) that 89% of patients on dialysis receive; a sustainable health workforce is the cornerstone of any healthcare system. The multimorbid nature of chronic kidney disease as well as the complexity-especially the technical aspects-of HD are deterrents for pursuing nephrology as a career. An educational platform that critically examines the essential issues and components of HD therapy was thus considered appropriate to create or renew interest in nephrology. By providing broader and newer perspectives of some of the core principles around which HD evolves, with this set of articles we seek to facilitate a better appreciation of HD. We believe that such a reappraisal of either poorly understood or ill-defined principles, including usage of terminology that is imprecise, will help facilitate a better understanding of the functioning principles of HD.
