Occupational lead poisoning in Ohio: surveillance using workers' compensation data

Area of Science:

• Occupational Health
• Environmental Health
• Public Health Surveillance

Background:

• Occupational lead poisoning remains a significant public health concern.
• Effective surveillance systems are crucial for identifying and mitigating lead exposure risks in the workplace.

Purpose of the Study:

• To evaluate the effectiveness of workers' compensation (WC) data for surveillance of occupational lead poisoning.
• To assess the correlation between WC claims and actual lead poisoning cases.

Main Methods:

• Review of WC claims for lead poisoning in Ohio from 1979-1983.
• Application of a defined case definition to claims attributed to lead exposure.
• Comparison of inspected vs. non-inspected companies by the Occupational Safety and Health Administration (OSHA).

Main Results:

• 81% of 114 lead-attributed WC claims met the case definition for lead poisoning.
• A strong correlation existed between the number of WC claims and the likelihood of a company having lead poisoning cases.
• OSHA inspections focused on specific industries, not necessarily those with the highest number of cases or largest company size.

Conclusions:

• Workers' compensation claims serve as a useful supplement to occupational lead poisoning surveillance systems.
• Further comparison with other surveillance methods, such as blood lead level monitoring, is warranted.
