Workers with work-related musculoskeletal injuries are at risk for developing posttraumatic stress injury. Accident type, severe injuries like fractures, public safety roles, and lower education increase this risk.
Area of Science:
- Occupational Health
- Trauma Psychology
- Public Health
Background:
- Work-related musculoskeletal injuries (MSI) are common and can lead to significant disability.
- Concurrent posttraumatic stress injury (PTSI) can exacerbate the impact of MSI, affecting recovery and return to work.
- Identifying risk factors for concurrent PTSI in MSI patients is crucial for targeted interventions.
Purpose of the Study:
- To investigate risk factors associated with developing concurrent posttraumatic stress injury (PTSI) in workers experiencing work-related musculoskeletal injury (MSI).
Main Methods:
- A case-control study design was employed.
- Workers' compensation data from injured workers undergoing rehabilitation were analyzed.
- Logistic regression models were used to identify predictors of concurrent MSI and PTSI.
Main Results:
- The study included 1948 workers; 215 had concurrent MSI and PTSI.
- Key predictors for concurrent MSI and PTSI included accident type (OR, 25.8), fractures/dislocations (OR, 3.7), public safety occupations (OR, 3.1), and lower education levels (OR, 1.9).
Conclusions:
- Concurrent PTSI diagnosis with MSI is associated with specific occupations, accident types, and educational backgrounds.
- These findings highlight the importance of considering psychological impact alongside physical injury in occupational health.
- Further research and targeted support are needed for high-risk worker populations.
