[Quality and efficacy in occupational medicine: relationship between quality, efficacy, and surveillance -- Experience of public and private facilities in Emilia Romagna].

Italian legislation concerning health and safety at work establishes minimal requirements, according to European regulations. On the other side it's compulsory for Employers to set themselves at a level "above minimal requirements" according only to technicalfeasibility. It's a duty of Control Bodies (in Italy National Health Service's Work Environment Prevention Services) to verify the respect of law's preview minimal requirements. Quality standards and application guidelines, on the contrary, require collaboration and consensus among all actors involved in the implementation of health and safety managing systems on workplaces: Control Bodies, Professional Officers (Occupational Physicians, Safety Consultants), public and private Consultant Companies working on the field of health and safety at work. In this document some Emilia Romagna Region Control Bodies guidelines are discussed, and two experiences concerning public and private Consultant Companies are presented.
