The present standard work on occupational medicine makes a contribution to this global target of the ICOH. It describes the fundamentals of quality-controlled occu- pational medical prophylaxis, which are in line with the stipulations for health sur- veillance found in the European Council Directive for improving the safety and health of workers at work. In some European countries the Guidelines for occupational medical examinations are already known as established procedures for the medical care of persons ex- posed to certain specific work-related health risks, especially hazardous substances, noise, airway disorders, risk of infection, skin disorders, but also work at VDU work- places and work involving strain on the musculoskeletal system. For decades, specialists in occupational medicine have been working on the basis of these guidelines which are generally accepted to provide a good basis for qualita- tively consistent procedures in occupational medical prophylaxis. The Guidelines are elaborated, kept up to date and further developed by teams of experts from all rel- evant fields under the auspices of the German Social Accident Insurance (Deutsche Gesetzliche Unfallversicherung, DGUV). The Guidelines recommend methods of ex- amination to be used and apparatus required, they include information about expo- sures, symptoms and syndromes, and give the physician support in advising the pa- tient and assessing the examination results. This standard work on occupational medicine is organized according to a universal concept and the resulting clear structure makes it easy to use in occupational medical practice. The German Social Accident Insurance, DGUV, which since its institution in 1884 has committed itself not only to compensation but also to the prevention of workplace accidents and occupational disease and to the rehabilitation of em- ployees, welcomes suggestions and comments for the improvement of the Guidelines.

J. Milde, German Social Accident Insurance (DGUV), Sankt Augustin 1.1 Occupational medical care Globalization and the increase in competition resulting from international trading have led to increasing expectations of workforce productivity in enterprises every- where in Europe. In addition, demographic developments are increasing the aver- age age of workers (the ageing workforce). The economic success of an enterprise depends on the abilities of well-trained and experienced employees. Thus, the main- tenance and promotion of health of employees is becoming increasingly important from both the social and economic points of view, to do justice to the demands of so- ciety for appropriate quality of work and also to provide a basis for economic suc- cess. A healthier work environment does not only provide competitive advantages, it becomes an indicator of the social acceptability of successful commerce. In the European Union, employers are required as part of their statutory “duty of care” to provide adequately for the health and safety of their employees. Although there are considerable differences between the relevant regulations in the various member states of the EU, there is a common basis which is described in the Council Directive 89/391/EEC and the associated individual directives. Occupational med- ical care, which is concerned with the interaction between work, profession and health, is covered by these directives. Its particular aims include: • assessment of working conditions (risk assessment) • provision of recommendations for improvement of working conditions • informing and advising the employees about work-related risks • early recognition and prevention of occupational diseases and work-related ill- nesses • improving our knowledge of exposures and risks. Thus occupational medical care does not only aim to keep employees healthy but also to bring about improvements in health protection at the workplace. By means of occupational medical care, the employer can demonstrate that he is meeting his “duty of care” responsibilities, provided that the medical care is provided by quali- fied specialists under quality-controlled conditions and the results are appropriately documented. 1.2 Risk assessment and health surveillance Fundamental to health and safety protection at the workplace is the risk assessment. For this purpose the employer assesses (before a person starts work and at certain 12 Guidelines for Occupational Medical Examinations intervals afterwards) whether and to what extent health and safety hazards for the employee are associated with the work. In this process he can use the support of health and safety experts and the works physician or an occupational health profes- sional. In principle, the employer is required to reduce any risks to a minimum and to institute any necessary general and individual protective measures. The risk assess- ment must be appropriately documented. If the results of the risk assessment suggest that in spite of all protective measures a significant risk for the health of an employee remains, occupational medical exami- nations carried out by a doctor or an appropriately qualified person should be con- sidered. The conditions under which occupational medical examinations are re- quired before an employee may begin or continue a job are stipulated by law. These examinations are therefore quite different from health check-ups or general exami- nations to establish whether a person is fit for work, which are not regulated by law nor associated with specific workplace exposures. Nonetheless, such medical exami- nations can also be a starting point for a general improvement of the health of a workforce and the maintenance of fitness for work; they are not the
