Abstract
AbstractBackground and ObjectiveRacial disparities have been documented in care of many respiratory diseases but little is known about the impact of race on the treatment of interstitial lung diseases. The purpose of this study was to determine how race and ethnicity influence treatment of idiopathic pulmonary fibrosis.MethodsAdults with idiopathic pulmonary fibrosis (>18 years) were identified using TriNetX database and paired‐wised comparisons were performed for antifibrotic treatment among White, Black, Hispanic and Asian patients. Mortality of treated and untreated IPF patients was compared after propensity score matching for age, sex, nicotine dependence, oxygen dependence and predicted FVC. Additional comparisons were performed in subgroups of IPF patients older than 65 years of age and with lower lung function.ResultsOf 47,184 IPF patients identified, the majority were White (35,082), followed by Hispanic (6079), Black (5245) and Asian (1221). When subgroups were submitted to matched cohort pair‐wise comparisons, anti‐fibrotic usage was lower among Black patients compared to White (6.2% vs. 11.4%, p‐value <0.0001), Hispanic (10.8% vs. 20.2%, p‐value <0.0001) and Asian patients (9.6% vs. 14.7%, p‐value = 0.0006). Similar treatment differences were noted in Black individuals older than 65 years and those with lower lung function. Mortality among White patients, but not Hispanic, Black, or Asian patients, was lower in patients on antifibrotic therapy versus not on therapy.ConclusionThis study demonstrated that Black IPF patients had lower antifibrotic use compared to White, Hispanic and Asian patients. Our findings suggest that urgent action is needed to understand the reason why racial disparities exist in the treatment of IPF.
