Objective: To investigate health and healthcare disparities after transcatheter aortic valve replacement (TAVR) and how they affect outcomes and resource utilization. Methods: We retrospectively reviewed TAVR patients from the National Inpatient Sample from 2012 to 2015. Patients were stratified by race and compared based on healthcare and health disparities. Outcomes were in-hospital complications, total procedural costs high resource utilization (HRU): length of stay ≥ 7 days or discharge to a location other than home. Results: Between 2012 and 2015, 57,830 patients who had TAVR in the United stated were stratified into African Americans (AA) (n=2265), Caucasians (CC) (n= 49,740), Hispanics (n=2265), Others (n=3,560). Compared to CC, Hispanics were more likely to undergo TAVR at low-volume (< 50 cases/year) centers (p< 0.0001). A higher number of AA and Hispanics than CC had TAVR at urban teaching centers (p=0.0003) and were less likely to be Medicare beneficiaries (p<0.0001). Distribution of TAVR patients in the lowest income quartile showed (AA: 49.5% vs. CC: 19.8% vs. Hispanic: 35% vs. Others: 17.3% p < 0.0001). In-hospital complications were higher among Hispanics than AA, CC and others (p=0.0007) and this translated to a prolonged LOS, costs and higher HRU. Independent predictors of HRU were (TAVR year: p< 0.0001, Sex (female): p<0.0001, Age: p <0.0001, lowest income quartile, p = 0.006 and insurance status (p=0.003).
Conclusions: There exist significant healthcare and health disparities among patients undergoing TAVR. Consequently, these unequal access to care and determinants of heath translate into higher costs and resource utilization.
