How occupational asthma is detected among workers participating medical surveillance?
Hille Suojalehto1, Kirsi Karvala1 and Irmeli Lindström1
Background: Medical surveillance including spirometry is periodically performed among workers who are exposed to agents causing occupational asthma in Finland. Surveillance has been shown to detect occupational asthma at an earlier stage, however only a few studies have assessed its benefits.
Aims: Our aim of was to assess the role of surveillance and spirometry in intiating occupational asthma examinations. We also evaluated the quality of the spirometry.
Methods: We retrospectively reviewed the medical files of 60 patients diagnosed with sensitizer induced occupational asthma at the Finnish Institute of Occupational Health in 2012-2014 and participated surveillance program. Information about work exposure, respiratory symptoms, the occupational or primary health care visit initiating examinations, first spirometry and the details of the diagnosis were collected.
Conclusions: Our results support the view that spirometry for non-symptomatic workers is not beneficial in occupational asthma surveillance and highlight the importance of work related nasal symptoms in detecting occupational asthma.
