Abstract
BACKGROUND: Despite widespread use of transjugular intrahepatic portosystemic shunt (TIPS) for treatment of portal hypertension, a paucity of nationwide data exists on predictors of the economic impact related to TIPS. AIMS: Using the National Inpatient Sample (NIS) database from 2001 to 2012, we aimed to evaluate factors contributing to hospital cost of patients admitted to US hospitals for TIPS. METHODS: Using the NIS, we identified a discharge-weighted national estimate of 61,004 TIPS procedures from 2001 to 2012. Through independent sample analysis, we determined profile factors related to increases in hospital costs. RESULTS: Of all TIPS cases, the mean charge adjusted for inflation to the year 2012 is $125,044 ± $160,115. The mean hospital cost adjusted for inflation is $44,901 ± $54,565. Comparing pre- and post-2005, mean charges and cost have increased considerably ($98,154 vs. $142,652, p < 0.001 and $41,656 vs. $46,453, p < 0.001, respectively). Patients transferred from a different hospital, weekend admissions, Asian/Pacific Islander patients, and hospitals in the Northeastern and Western region had higher cost. Number of diagnoses and number of procedures show positive correlations with hospital cost, with number of procedures exhibiting stronger relationships (Pearson 0.613). Comorbidity measures with highest increases in cost were pulmonary circulation disorders ($32,157 increase, p < 0.001). CONCLUSION: The cost of the TIPS procedure is gradually rising for hospitals. Alongside recent healthcare reform through the Affordable Care Act, measures to reduce the economic burden of TIPS are of increasing importance. Data from this study are intended to aid physicians and hospitals in identifying improvements that could reduce hospital costs.
