The objective of this study was to investigate the psychological impact of screening for lung cancer and occupational pulmonary disease among asbestos-exposed workers. Altogether, 633 workers were screened with chest computed tomography (627 men, 6 women, mean age 64.5 years). Participants' views on the necessity of screening,awareness of asbestos-exposure risks, their perceived lung cancer risk, trial adherence intention, health anxiety,and worry about lung cancer were assessed. Health anxiety was reduced significantly after screening (P < 0.001). After 1 year, no significant long-term psychological differences were found between those who immediately received clear results and those who were submitted to additional examinations because of positive findings. In conclusion,computed tomography screening of pulmonary disease was well accepted and did not produce excessive long-term anxiety or other negative psychological effects,which could prevent the participation in the future screening programs.

There seems to be a dose-response relationship between the cumulative lifetime vibration dose of the HAV and finger blanching, sensorineural symptoms, symptoms of CTS and musculoskeletal symptoms of upper limbs and neck in the group of metalworkers of the study. The risk for neurosensory symptoms was the most significantly related to exposure to HAV and also to impulse vibration. Further studies are needed to confirm the present results also in other occupational groups taking into account the possible synergistic effect of workload as well.

Although the diagnostic procedures were mostly of sufficient quality, the performance of serial measurements of PEF at the workplace and the time to diagnosis should be substantially improved.

The findings of the present study suggest that symptoms related to HAV exposure significantly diminish the quality of life. This impairment can be seen in the different dimensions of well-being that are measured by EQ-5D. EQ-5D seems to correlate with both the severity of symptoms and the cumulative exposure index, and can thus be recommended as part of the health examination of workers exposed to HAV.
