Evaluating outcomes of transjugular intrahepatic portosystemic shunt procedure among Native Americans

Background:
This study aims to explore racial disparities in immediate outcomes of Transjugular Intrahepatic Portosystemic Shunt (TIPS) among Native Americans, a group that have higher prevalence of liver cirrhosis but were the "invisible group" in previous TIPS studies due to their small population size.
Methods:
The study identified Native Americans and Caucasians who underwent TIPS in National/Nationwide Inpatient Sample (NIS) database from Q4 2015-2020. Preoperative factors, including demographics, indications for TIPS, comorbidities, etiologies for liver disease, primary payer status, and hospital characteristics, were matched by 1:5 propensity score matching. In-hospital post-TIPS outcomes were then compared between the two cohorts.
Results:
There were 6,658 patients who underwent TIPS, where 101 (1.52%) were Native Americans and 4,574 (68.70%) were Caucasians. Native Americans presented as younger, with a lower socioeconomic status, and displayed higher rates of alcohol abuse and related liver diseases. After propensity-score matching, Native Americans had comparable in-hospital post-TIPS outcomes including mortality (8.33% vs 9.09%, p = 1.00), hepatic encephalopathy (18.75% vs 25.84%, p = 0.19), acute kidney injury (28.13% vs 30.62%, p = 0.71), and other adverse events. Native Americans also had similar wait from admission to operation (2.15 ± 0.30 vs 2.87 ± 0.21 days, p = 0.13), hospital length of stay (7.43 ± 0.63 vs 8.62 ± 0.47 days, p = 0.13), and total costs (158,299 ± 14,218.2 vs 169,425 ± 8,600.7 dollars, p = 0.50).
Conclusion:
Native Americans had similar immediate outcomes after TIPS compared to their propensity-matched Caucasians. While these results underscore effective healthcare delivery of TIPS to Native Americans, it is imperative to pursue further research for long-term post-procedure outcomes.
