I principi ed i metodi della III edizione delle Linee Guida della Società Italiana di Nefrologia (2005-2006) = The Italian Society of Nephrology Guidelines (3rd Edition) : principles and methods

Scientific Societies at both a local and international level are making big effort to prepare their clinical practice guidelines. The Italian Society of Nephrology has already published in two previous editions a series of guidelines relating to various aspects of management and diagnosis of different renal diseases. In this review we present the criteria of the 3(rd) edition of the Italian Society of Nephrology guidelines. This 3(rd) edition of guidelines will be based on the availability of scientific evidence in different areas of nephrology, dialysis and transplantation. Ten key intervention questions have been identified, based on the availability of systematic reviews of randomized trials or individual randomized address them. Systematic reviews and randomized trials are the optimal study design to address intervention questions. These have been summarized based upon rigid methodological criteria and strictly reflect the evidence basis. The different phases of development and publication of the 3(rd) edition of the Italian Society of Nephrology guidelines are presented.
