This study found that Black, Hispanic, and Asian individuals have higher odds of persistent high-dose steroid use compared to White individuals. Sustained access to outpatient care and the development of standardized steroid-tapering regimens from clinical trials with diverse populations may be targets for intervention to mitigate disparities in steroid-related adverse outcomes.
Objective: Glucocorticoids (steroids) are frequently used in systemic lupus erythematosus (SLE). Prolonged use may contribute to racial/ethnic disparities in avoidable adverse outcomes. We examined racial/ethnic differ-ences in longitudinal patterns of steroid use and dose.Methods: We identified Medicaid beneficiaries 18-65 years with incident SLE who received steroids for 12 months following the index date. Group-based trajectory modeling was used to identify patterns of daily prednisone-equivalent steroid doses. We examined demographic, clinical and healthcare utilization factors during the baseline period and used multinomial logistic regression to estimate the odds of belonging to the higher vs. lowest steroid dose trajectories over time.Results: We identified 6314 individuals with SLE with >= 1 dispensed steroid prescription. The mean (SD) prednisone-equivalent dose was 7 (23) mg/day for Black, 7 (26) for Hispanic, 7 (13) for Asian, and 4 (10) for White individuals. Adjusted multinomial models demonstrated higher odds of belonging to the highest vs. lowest steroid trajectory for Black (OR 2.07, 95% CI 1.65-2.61), Hispanic (OR 1.81, 95% CI 1.38-2.39), and Asian (OR 2.42, 95% CI 1.53-3.83) vs. White individuals. Having >5 outpatient visits during the baseline period was associated with lower odds of being in the persistently high-dose steroid trajectory (OR 0.77; 95% CI 0.60-0.98).Conclusion: Black, Hispanic, and Asian (vs. White) individuals had higher odds of persistently high-dose steroid use. Sustained access to outpatient care and the development of standardized steroid-tapering regimens from clinical trials with diverse populations may be targets for intervention to mitigate disparities in steroid-related adverse outcomes.
