It may therefore be advisable to use other methods to back this up. These would include questionnaires on consumption, (an example of which is shown in Appendix A5.), drinking diaries', and physical examination2. A fairly recent practical approach to determining alcohol use has been found in the form of Carbohydrate Deficient Transferrin (CDT) analysis. This test measures the percentage of total transferrin made up by CDT, and is elevated in people with raised alcohol intake6.
Once it has been discovered that an employee has an alcohol problem, and they admit to it, they may be sent to occupational health and/or put on to the company alcohol policy. Occupational health is a multifaceted activity concerned with the prevention of ill health in employed situations. In more economically developed countries many of the older occupational diseases are under control and, as such, the role of the occupational health service in this country is more to do with the control of occupational diseases than dealing with the sick or injured. Some of the functions of occupational health include advising on health and safety, assisting in control of sickness absence, managing rehabilitation, designing and managing substance abuse programmes and many more7. Within these functions comes the management and treatment of alcohol misuse. Due to the increased risk to health and safety that alcohol misuse in the workplace presents, company occupational health services have begun creating and implementing alcohol policies (examples of model alcohol policies are shown in appendices B and C).
Alcohol policies are introduced in order to reduce adverse effects of alcohol on employee health and safety, to encourage sensible drinking and to ensure fair and even-handed treatment8. The employer may also benefit because treating an employee may be cheaper than recruiting and training another. The first step in a company alcohol policy is the suspicion of alcohol misuse by an employee.
