Summary
Repetitive strain injuries (RSIs) represent a significant portion of upper limb workers' compensation claims, incurring higher costs and longer recovery times. Intensified prevention strategies are crucial to mitigate the impact of these injuries.
Area of Science:
- Occupational Health
- Epidemiology
- Musculoskeletal Disorders
Background:
- Repetitive strain injuries (RSIs) are a growing concern in occupational health.
- Understanding the epidemiology and economic impact of RSIs is vital for prevention.
Purpose of the Study:
- To analyze the characteristics, costs, and outcomes of upper limb RSI claims in Manitoba.
- To identify high-risk occupations and industries for RSIs.
Main Methods:
- Review of workers' compensation board (WCB) claims in Manitoba for 1991.
- Analysis of diagnoses, demographics, symptom duration, occupation, industry, costs, and return-to-work rates for upper limb claims.
Main Results:
- RSIs accounted for 9.3% of upper limb WCB claims, with tendonitis and carpal tunnel syndrome being most frequent.
- Food/beverage processing and metal product manufacturing had the highest RSI rates; meat processing and airplane manufacturing were high-risk industries.
- RSI claims were more costly, required more time loss, and had lower return-to-work rates compared to non-RSI musculoskeletal claims.
Conclusions:
- The significant cost and severity of RSI claims necessitate enhanced preventive measures.
- Targeted interventions in high-risk industries and occupations are recommended.
