Longitudinal assessment of lung function decline in the occupational setting

Area of Science:

• Occupational Medicine
• Pulmonary Function Testing
• Epidemiology

Background:

• Spirometry is vital for medical surveillance in workers with hazardous occupational exposures.
• Many clinicians lack familiarity with workplace surveillance and longitudinal spirometry interpretation.
• Evaluating lung function trends is key to identifying early respiratory disease and assessing intervention effectiveness.

Purpose of the Study:

• To review the interpretation of longitudinal spirometry in the workplace.
• To highlight important considerations for assessing lung function over time.
• To discuss recent studies on occupational exposures and lung function.

Main Methods:

• Review of a recent American Thoracic Society technical standards report.
• Analysis of key considerations in longitudinal lung function assessment.
• Synthesis of recent studies on occupational exposures and their impact on lung function.

Main Results:

• Recent studies have identified novel occupational respiratory diseases, such as flavoring-related lung disease.
• Understanding of familiar exposures like mineral dusts has advanced.
• Longitudinal spirometry interpretation is becoming increasingly important for clinicians.

Conclusions:

• Clinicians require enhanced skills to evaluate longitudinal spirometry in exposed workers.
• Identifying thresholds for further evaluation is essential.
• Longitudinal spirometry aids in early detection and management of occupational lung diseases.
