Abstract

Alcohol use disorder (AUD) increases risk of traumatic spinal cord injury (SCI) and is associated with depression, anxiety, and chronic pain. Given that these neuropsychiatric morbidities are frequently observed in SCI patients, the effects of pre-injury AUD on risk of depression, anxiety, or chronic pain were analyzed using an insurance claim database. Of 10,591 traumatic SCI patients, 507 had AUD-associated claims in a 12-month period before injury. Those AUD-positive SCI patients showed distinct demographic characteristics, including greater representation of men, younger age, more comorbidities, lower coverage by commercial insurance, and more cervical-level injuries. The AUD group also showed elevated pre-injury comorbidity of depression, anxiety, and chronic pain. However, multi-regression analysis revealed an increased odds ratio (OR) of de novo diagnosis of post-SCI depression in AUD patients 6 months (1.671; 95% confidence interval [CI]: 1.124, 2.483) and 1 year post-injury (1.511; 95% CI: 1.071, 2.131). The OR of de novo post-SCI anxiety was unaffected by pre-injury AUD. Finally, 1 year after SCI, pre-injury AUD increased the OR of de novo diagnosis of post-injury chronic pain (1.545; 95% CI: 1.223, 1.951). Thus, pre-injury AUD may be a risk factor for development of depression and chronic pain after traumatic SCI.
