An Interoperability Model for the Development of Occupational Health Professionals Practice

Introduction
The development of national and international networks caused the need for interoperability in all directions, not limited to the organizational hierarchy, but expanding to the community of professionals, which would be oriented towards sustainable development of occupational health. The interoperability means the capacity of the systems and processess to exchange and use toghether the data and information. Interoperability has two dimensions: one technical and one business. From the technical perspective, the four pillars of interoperability are: products, communities, access and standards.

Methods
An experimental product is a software application that meets the medical and IT standards, providing access to all occupational medicine professionals, to the maintenance of health at work in a labor market which is flexible, competitive, relatively regulated. "Application of information transfer" is a pilot project developed in Bucharest, aimed at facilitating electronic transfer of data between institutions responsible for occupational health. This program ensures the creation of the database by entering information shared, according to regulations, by all partners, employer, occupational medicine physicians, insurers, labor inspector, by direct access with personally password at http://medicinamuncii.dspb.ro. The system only works with "elements" characterized by identifiers, such as personal identification numbers (for individuals), National Economic Activity Code (for businesses), Occupations Code Romania (professions), International Classification Diseases - classification codes 999 and extended classification (occupational diseases), etc. 

Results
Modules, which will be presented, assure the passway from “health event” that it manages by occupational health professionals (medical, therapeutic, informational and preventive - illness caused by working conditions) to the complex phenomenon of “occupational health”, a phenomenon that involves all professionals in health and safety at work and is widely described by indicators.

Discussion
The interoperability is the support for strategic, organizational, semantic and integrative choesiune inside the systems and networks for the occupational medicine profesionals and its partners for occupational health protection and promotion.
