ABSTRACT
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. Professional associations must be active to foster the integrity of their members and to minimize the risk of conflict of interests, also to avoid wasting resources, making the health system fairer and more sustainable.
