Wengenroth et al. describe the construction and use of an online teaching tool concerned with occupational health. The application is designed for students, to help them understand the need for pre-employment health checks and consider possible health barriers--for example, allergies or asthma--to a career they may be considering.

The authors designed a number of virtual patients that could potentially have problems with their choice of career due to occupational health factors. The system was tested in a number of schools, and the students found the system easy to use. However, there weren’t any clear benefits to learning about occupational health issues from the system, and there were some technical difficulties in terms of the experimental trial. Thus, further work is required to prove its benefits. It should be noted: the system is available online.
