Higher In-Hospital Mortality among Asian Americans Undergoing Transjugular Intrahepatic Portosystemic Shunt Procedure.

BACKGROUND

Transjugular intrahepatic portosystemic shunt (TIPS) is a procedure to alleviate portal hypertension in patients with decompensated liver cirrhosis. While prior research highlighted racial disparities in TIPS, Asian Americans were not included in the investigation. This study aimed to investigate disparities in the immediate postprocedural outcomes among Asian American patients who underwent TIPS.

METHODS

The study identified Asian American and Caucasian patients who underwent TIPS in the National Inpatient Sample from Q4 2015-2020. Preprocedural factors, including demographics, comorbidities, primary payer status, and hospital characteristics, were matched by 1:2 propensity-score matching between the groups. In-hospital outcomes after TIPS were examined.

RESULTS

There were 6,658 patients who underwent TIPS with 128 (1.92%) Asian Americans and 4,574 (68.70%) Caucasians, where 218 Caucasians were matched to all Asian Americans. Asian Americans had higher in-hospital mortality (14.06% vs. 7.34%, p = 0.04) and higher total hospital charge (253,756 ± 37,867 vs. 163,391 ± 10,265 US dollars, p = 0.02). The occurrence of hepatic encephalopathy, acute kidney injury, transfers out to other hospital facilities, and length of stay did not differ between cohorts.

CONCLUSION

Despite their heightened risk for cirrhosis, Asian Americans are significantly underrepresented in TIPS and had higher in-hospital mortality after TIPS. This highlights the need for enhanced access to diagnosis and treatment care of liver cirrhosis for Asian Americans.
