In our occupational health service, we have worked out a fairly simple model for risk score for coronary heart disease. The occupational nurses give each employee a risk score after health examination and use this figure as a convincing pedagogic tool in preventive health education. The nurses find a measureable scale extremely useful in the follow-up of groups and individuals. The system is also used to measure the difference in coronary disease risk between different occupations and occupational subgroups. After introduction of this risk score system, both employer and employees seem to be more conscious of health hazards, both in the work environment and due to personal lifestyle.
