[Quality control of spirometry in workers' medical surveillance]. / Il controllo di qualità della spirometria nella sorveglianza sanitaria dei lavoratori.

Spirometry plays an important role in occupational respiratory health surveillance programs. However, when not performed correctly, the values obtained can be misleading, resulting in misclassification of the workers' health status. Studies carried out in Italy have shown that spirometries recorded by occupational physicians often do not comply with quality criteria for recording FEV1 and FVC, according to joint statements on lung function testing for the American Thoracic Society and the European Respiratory Society, issued in 2005. For this reason, they are useless for the purposes of their execution. Compliance with ATS/ERS statements is essential to assure that spirometry results are beneficial for the monitoring of workers' health.

[Smoking in the workplace. Study at a hospital in central Italy]. / L'abitudine al fumo di tabacco nei luoghi di lavoro. Studio in un'Azienda Ospedaliera dell'Italia centrale.

Smoking is the leading preventable cause of death and the source of numerous problems in the workplace. This study assessed the smoking in health care workers in a general hospital in Central Italy. As part of the health surveillance required by Law No. 626/1994, 2743 employers (40.8% males, 59.2% females; mean age 42.0 ys, SD 9.6 ys) were interviewed. The prevalence of smokers was very high: 36.0% in men and 36.7% in women. When the population was stratified according to occupation, the highest prevalence of smokers was found in ward orderlies (45.2%) and nurses (38.9%) and the lowest in doctors (26.3%). The prevalence of smoking was similar in all occupational divisions--clinical, surgery, diagnostics and administration. This study shows that smoking is more widespread in hospital workers than in an age-matched section of the general population (27.5%). As all health workers should set a positive example in combatting smoking, occupational physicians in charge of health surveillance in hospitals should actively collaborate in smoking dissuasion programmes.
