The impact of race on hospitalization outcomes for goodpasture’s syndrome in the United States: nationwide inpatient sample 2003–2014

ABSTRACT Background Goodpasture’s syndrome is a rare and life-threatening autoimmune disease. While Goodpasture’s syndrome is well described in Caucasian and Asian populations, its prevalence and outcomes among African American and Hispanic populations are unclear. We conducted this study to assess the impacts of race on hospital outcomes among patients with Goodpasture’s syndrome. Methods The National Inpatient Sample database was used to identify hospitalized patients with a principal diagnosis of Goodpasture’s syndrome from 2003 to 2014. Goodpasture’s syndrome patients were grouped based on their race. The differences in-hospital supportive care for organ failure and outcomes between Caucasian, African American, and Hispanic Goodpasture’s syndrome patients were assessed using logistic regression analysis. Results Nine hundred and sixty-four patients were hospitalized with a primary diagnosis of Goodpasture’s syndrome. Of these, 786 were included in the analysis: 622 (79%) were Caucasian, 73 (9%) were African American, and 91 (12%) were Hispanic. Hispanics had significantly lower use of plasmapheresis. The use for mechanical ventilation, noninvasive ventilation support, and renal replacement therapy in African Americans and Hispanics were comparable to Caucasians. There was no significant difference in organ failure, sepsis, and in-hospital mortality between African Americans and Caucasians. In contrast, Hispanics had higher in-hospital mortality than Caucasians but similar risk of organ failure and sepsis. Conclusion African American and Hispanic populations account for 9% and 12% of hospitalizations for Goodpasture’s syndrome, respectively. While there is no significant difference in in-hospital mortality between African Americans and Caucasians, Hispanics with Goodpasture’s syndrome carry a higher in-hospital mortality compared to Caucasians.
