Investigating the Risk of First Occupational Injury by Treated Psychiatric Disorder Episodes of Care
Methods: This was a historical cohort study of US workers from a large oilfield services corporation employed sometime between January 1, 2005 and June 30, 2011. Administrative, mental health claims and work-related injury data were integrated to construct an occupational cohort. A cox proportional hazards model was fit to the data to model time to first occupational injury with psychiatric disorder treated episode as the predictor. Adjusted hazard rates and 95% confidence intervals were calculated for occupational injury risk.
Results: The cohort consisted of 18,144 workers. A total of 2,302 employees (13%) sustained an occupational injury over a mean follow-up of 2.7 years. Workers with a disorder had an 84% lower risk of first occupational injury compared to employees without a disorder (HR = 0.16; 95% CI 0.07 to 0.39) after adjustment.
Conclusion: This study provides some preliminary evidence for a reduced risk of first occupational injury among employees with a treated psychiatric disorder in the oil and gas industry.
