Methodology of the National Guidelines System

The SNLG produces, updates and disseminates evidence-based recommendations for clinical practice following a set of defined rules.

The methodology is detailed in the Methodological handbook – How to produce, disseminate and update clinical practice recommendations.

An update of the Handbook, including the latest improvements, will be soon available.


The SNLG has also drawn up a specific methodology for the organization of Consensus Conferences. The methodological indications are included in the Methodological handbook - How to organize a Consensus Conference.
