Management of occupational asthma

Area of Science:

• Occupational Health
• Respiratory Medicine
• Environmental Health

Background:

• Asthma incidence, morbidity, and mortality are increasing in the general population.
• Occupational asthma contributes significantly to the overall burden of asthma.
• Lifetime risk for workers in certain industries can approach 5%.

Purpose of the Study:

• To outline management strategies for occupational asthma in both affected industries and individuals.
• To highlight the importance of early diagnosis and preventive measures.
• To discuss the role of industrial hygiene and exposure reduction.

Main Methods:

• Review of current trends in asthma incidence and occupational asthma contribution.
• Analysis of management pathways for industries and affected workers.
• Evaluation of preventive strategies including industrial hygiene, agent substitution, and worker surveillance.
• Discussion on the limited role of worker selection and the benefits of job reassignment.

Main Results:

• Occupational asthma incidence ranges from 20-100 cases per million workers per year.
• Effective management requires industry-level identification of causative agents and problem assessment.
• Preventive measures like improved industrial hygiene and agent substitution are most promising.
• Worker surveillance aids in early disease recognition.

Conclusions:

• Prompt diagnosis is crucial for managing occupational asthma in both individuals and industries.
• Improving industrial hygiene and substituting hazardous agents are key preventive strategies.
• Job reassignment offers the best recovery chance but faces practical challenges.
