National Collaborating Centre for Chronic ConditionsThe National Collaborating Centre for Chronic Conditions (NCC-CC) is a collaborative, multiprofessional centre undertaking commissions to develop clinical guidance for the National Health Service (NHS) in England and Wales. The NCC-CC was established in 2001. It is an independent body, housed within the Clinical Standards Department at the Royal College of Physicians of London. The NCC-CC is funded by the National Institute for Health and Clinical Excellence (NICE) to undertake commissions for national clinical guidelines on an annual rolling programme.

PrefaceChronic kidney disease (CKD) is of growing importance in the UK. The NHS is increasingly focussing on prevention and on the early detection and treatment of potentially progressive disease, whilst the prevalence of risk factors for CKD, such as diabetes, obesity and hypertension is rising. It is therefore a great pleasure to introduce this timely new guideline on CKD from the National Collaborating Centre for Chronic Conditions (NCC-CC) and the National Institute for Health and Clinical Excellence (NICE). The recommendations you will read here are the result of a thorough review of the published research. The field of renal medicine has a complex evidence base, and enormous thanks are due to the Guideline Development Group for their hard work and attention to detail, and to the NCC-CC Technical Team who worked enthusiastically alongside them. As for all our guidelines, full evidence tables summarising the clinical evidence base, and full details of the health economic modelling, are available from the Royal College of Physicians website. Readers involved in research in this field, and those who want to find the full rationale behind a particular recommendation, will find this an invaluable resource. The Department of Health, in commissioning this guideline, was clear that the focus was to be on early detection and management. This is the area in which the guideline can deliver its greatest potential benefit, through delaying progression of disease and thus reducing the need for dialysis or transplantation. The key priority recommendations singled out in the guideline reflect this emphasis. They present clear criteria for testing for CKD, suspecting progressive CKD, and referring people for specialist assessment, all of which should be useful in primary care. Recommendations are also provided on starting
