Abstract
BACKGROUND: Stanford Type A Aortic Dissection (TAAD) is an emergent condition with high in-hospital mortality. Gender disparity in TAAD has been a topic of ongoing debate. This study aimed to conduct a population-based examination of gender disparities in short-term TAAD outcomes using the National/Nationwide Inpatient Sample (NIS) database, the largest all-payer database in the US. METHODS: Patients undergoing TAAD repair were identified in NIS from the last quarter of 2015-2020. Multivariable logistic regressions were used to compare in-hospital outcomes between male and female patients, adjusted for demographics, comorbidities, hospital characteristics, primary payer status, and transfer status. RESULTS: There were 1454 female and 2828 male patients identified who underwent TAAD repair. Female patients presented with TAAD were at a more advanced mean age (64.03 ± 13.81 vs. 58.28 ± 13.43 years, p < 0.01) and had greater comorbid burden. Compared to male patients, female patients had higher risks of in-hospital mortality (17.88% vs. 13.68%, adjusted odds ratio (aOR) = 1.266, p = 0.01). In addition, female patients had higher pericardial complications (20.29% vs. 17.22%, aOR = 1.227, p = 0.02), but lower acute kidney injury (AKI; 39.96% vs. 53.47%, aOR = 0.476, p < 0.01) and venous thromboembolism (VTE; 1.38% vs. 2.65%, aOR = 0.517, p = 0.01). Female patients had comparable time from admission to operation and transfer-in status, longer hospital stays, but fewer total hospital expenses. CONCLUSION: Female patients were 1.27 times as likely to die in-hospital after TAAD repair but had less AKI and VTE. While there is no evidence suggesting delay in TAAD repair for female patients, the disparities might stem from other differences such as in care provided or intrinsic physiological variations.
