Racial/Ethnic Groups
Out of the 25,260 hospital admissions, 68.1% (n= 17,197) were whites/Caucasian, 19.6% (n= 4,959) were black/African American, 5.7% (n= 1,462) Hispanic and 6.5% (n= 1,642) were classified as “others” (2.9% Asian or pacific islanders and 0.4% native Americans). Overall, there was a relative marginal increase in the proportion of TEVARs performed from 2013 onwards. Specifically, the race-adjusted procedural incidence rate for black population went from 1.14 cases per 100 000 persons in 2012 to 2.03 cases per 100 000 persons in 2015 (Figure 2 )
Overall, TEVAR was more frequently secondary to DTAA (58.8% vs 34% vs 48.3% vs 48.2%; p<0.001) among white population; they had more often CAD (34.6% vs 24.1% vs 26.8% vs 24.7%; p<0.001), and COPD (28.7% vs 15.6% vs 15.1% vs 16.5%; p<0.001). In contrast, black population had a younger median age, presented more frequently with type B dissection (41.1% vs 65.6% vs. 51.6% vs 51.7%; p<0.001), or hypertension as a comorbidity (83% vs 92% vs 85% vs 84%; p<0.001). A higher proportion of the black population had a median household income below the percentile 25th (24.2% vs 52.1% vs 34.9% vs 22.6%; p<0.001) (Table 1 ).
