Professional societies throughout the world, including the Canadian Society of Nephrology (CSN), agree there is a need for developing
clinical practice guidelines for patients with chronic kidney disease (CKD). However, as illustrated by the case of the plethora of anemia
guidelines for CKD that have been completed (and updated) by many national professional societies since 2000,1-5 creation of guidelines by individual professional societies results in significant duplication of effort. In this context, KDIGO (Kidney Disease: Improving Global Outcomes) was established in 2003 with its stated mission to “improve the care and outcomes of kidney disease
patients worldwide through promoting coordination,collaboration, and integration of initiatives to develop and implement clinical practice
guidelines.

The KDIGO Clinical Practice Guideline for the Diagnosis, Evaluation, Prevention, and Treatment of Chronic Kidney Disease–Mineral and Bone Disorder (CKD-MBD) represents a 2-year comprehensive effort to review the relevant evidence in CKD-MBD。 The CSN congratulates KDIGO on an excellent review of the available evidence.
