Race and socioeconomic differences in post-settlement outcomes for African American and Caucasian Workers' Compensation claimants with low back injuries

The purpose of this study was to predict post-settlement pain intensity, psychological distress, disability, and financial struggle among African American (n = 580) and non-Hispanic Caucasian (n = 892) Workers' Compensation claimants with single incident low back injury. The study was a population-based telephone survey conducted in three population centers in Missouri. Post-settlement outcomes were predicted from claimant demographics (race, age, gender); socioeconomic status (SES); diagnosis and legal representation; and Workers' Compensation resolution variables (treatment costs, temporary disability status, disability rating, settlement costs). Simultaneous-entry, hierarchical multiple linear regression analyses indicated that African American race and lower SES predicted higher levels of post-settlement pain intensity, psychological distress (general mental health, pain-related catastrophizing), disability (pain-related role interference), and financial struggle, independent of age, gender, diagnosis, legal representation, and Workers' Compensation resolution variables. The results suggest that African American race and lower SES-relative to Caucasian race and higher SES-are risk factors for poor outcomes after occupational low back injury. Mechanisms to explain these associations are discussed, including patient-level, provider-level, legal, and Workers' Compensation system-level factors.
