Chronic kidney disease and renal replacement therapy: an overview for the advanced clinical practitioner.

Chronic kidney disease (CKD), also known as chronic renal failure (CRF), is a common, globally significant condition, with associated significant mortality and morbidity. Due to the disease prevalence, advanced clinical practitioners (ACPs) in a variety of primary and secondary care settings will encounter patients with this diagnosis who will require care and treatment. This article examines definitions of CKD, describes a clinical approach to a patient with CKD, including key history and examination findings, and provides a brief overview of renal replacement strategies for the patient with end-stage renal failure.
