Assessment of Work-Related Asthma Cases: our three-year experience

Objective: Work-related asthma (WRA) is one of the most common occupational diseases. In this study, we aimed to review diagnosing procedures and the characteristics of patients who were diagnosed with WRA.

Methods: Between November 2013 and June 2016; 214 patients were referred to our clinic with WRA suspicion by an occupational health specialist, personal visit, chest disease specialists [61 (28%), 51 (23%), and 102 (47%) respectively]. Occupational history, functional and radiological assessment, skin prick test, PEF monitoring were done.

Results: Fifty-four patients (25%) were diagnosed with OA, and 24 (11%) with WEA, total 78 workers were diagnosed with WRA. Twenty-five (32.1%) had allergic rhinitis, 13 (16.7%) had allergic dermatitis, and 8 (10%) had both diseases.

Conclusion: WRA can be seen in many areas. Complaints are the basic route for admission to physician, and the diagnosis can be delayed for a long time as one year. Lower rates of referral by occupational health physicians are the signs of limitations on management of cases. Non-specific BPT and skin prick test for selected cases would be sufficient besides occupational history and clinical examination for the diagnosis of WRA. PEF assessment, one of the most important tests for the diagnosis of WRA, must be performed.
