The "accident prone" worker: an example from heavy industry

Area of Science:

• Occupational Health
• Industrial Safety
• Epidemiology

Background:

• Workplace injuries are a significant concern in heavy industry.
• Previous studies suggested accident-prone individuals contribute disproportionately to injury rates.
• The stability of injury patterns within a workforce requires further investigation.

Purpose of the Study:

• To determine if excessive injuries in a heavy industry workforce are concentrated in specific individuals over time.
• To assess the impact of removing high-injury-risk workers on future injury occurrence.
• To analyze injury patterns using medically attended injuries while controlling for confounding factors.

Main Methods:

• Analysis of medically attended injuries in a heavy industry workforce across two successive time periods.
• Statistical control for job hazards, worker exposure, age, and changes in job/location.
• Comparison of observed injury proportions with chance expectations.

Main Results:

• The proportion of workers with excessive injuries did not exceed chance expectations in successive periods.
• Evidence of stable 'accident repeaters' within this workforce was not found.
• Removing workers with excessive injuries in one period would not substantially decrease injuries in subsequent periods.

Conclusions:

• Injury occurrence in this heavy industry workforce appears to be largely random and not attributable to a stable group of repeat offenders.
• Interventions targeting specific 'repeaters' may not be an effective strategy for reducing overall workplace injuries.
• Future injury prevention efforts should consider broader systemic factors beyond individual worker behavior.
