[National Guidelines System: the Italian experience].

The Italian's experience of the guidelines development group is discussed through the evaluation of its ten years of activity. Focus is placed on the Italian guidelines working group organization and on the kind of documents developed. The horizontal architecture of the system and the several partnerships settled over time allowed the definition of a small coordinating group connected with a multitude of territorial stakeholders, such as scientific societies and local health units pertaining to the Italian National Health System. Different kinds of documents were produced, as adaptations of already existing guidelines elaborated by international institutions, short reviews addressing specific clinical issues and consensus conferences aimed at providing clinical governance on issues which lack on evidence. The steps needed to produce a high quality guideline are presented, considering and comparing all the different international experiences, to define and discuss a common and well-structured methodology, and to face the ethical and epistemological implications of each method. The multidisciplinary of the working groups, the importance of the active surveillance on conflicts of interests, the definition of a minimum set of rules to be followed during the whole activity and the transparency of all the steps are the milestones of the Italian experience. The lack of a continuous and stable source of funding and the subsequent instability of the central structure are endangering all the knowledge and the experience gained during these years of activity. It is therefore crucial to guarantee and safeguard the role of a national, independent and public institution in the supervision of the guidelines development process and the provision of clinical governance.
