Preinjury Social Determinants of Health Disparities Predict Postinjury Psychosocial Conditions in Adult Traumatic Brachial Plexus Injuries.

BACKGROUND

Adult traumatic brachial plexus injuries (TBPIs) are life-altering events that can have detrimental effects on a patient's quality of life.

OBJECTIVE

To examine how social determinants of health (SDOH) disparities influence the risk of developing new psychosocial conditions after TBPIs in previously psychiatric-naïve patients.

METHODS

Between January 2010 and June 2019, a retrospective analysis was performed using PearlDiver's Mariner, an all-payer claims database, to create 3 cohorts: TBPI disparity cohort: patients with TBPI and presence of at least 1 SDOH disparity before injury, TBPI without disparity cohort: patients with TBPI and the absence of any SDOH disparity, and control cohort: patients without TBPIs.

RESULTS

The matched population analyzed in this study consisted of 1176 patients who were equally represented in the TBPI disparity cohort (n = 392, 33.33%), TBPI without disparity cohort (n = 392, 33.33%), and control cohort (n = 392, 33.33%). A total of 301 patients developed any psychosocial condition with 4 years of their injury. Patients in the TBPI disparity cohort had significantly higher rates of developing any psychosocial condition (31.12%, P < .0005), depression (22.70%, P = .0032), anxiety (18.62%, P = .0203), drug abuse (7.91%, P = .0060), and alcohol abuse (4.85%, P = .03499) when compared with the other cohorts. Furthermore, the disparity cohort carried a significantly increased risk of developing any psychosocial condition (hazard ratio 1.42, 95% CI 1.09-1.86). The rates of suicide attempt, post-traumatic stress disorder, and divorce did not significantly differ between groups.

CONCLUSION

TBPI patients with SDOH disparities are at increased risk of developing new-onset psychosocial conditions, such as depression, anxiety, drug abuse, and alcohol abuse. Level of Evidence: Prognostic Level III.
