[Professional societies and conflict of interests governance.].

The complexity of health systems often implies a condition of conflict of interests for many of the players involved: health professionals, managers of the NHS, pharmaceutical, medical devices or food industries, publishers and communication agencies, conference event organizers. Conflict of interests is a condition of risk, not a sentence of guilt: for this reason, conflict of interests should be managed through information and training of health personnel. Scientific societies play an important role being active in updating their members (conferences, meetings, e-learning and residential training courses) and influencing healthcare with the production of clinical practice guidelines.
