Abstract
BACKGROUND/AIM: The prevalence, characteristics, burden and trends of primary biliary cholangitis (PBC) hospitalizations in the USA remain unclear. METHOD: We identified primary PBC hospitalizations from the National Inpatient Sample (NIS) 2007 through 2014 using ICD-9-CM codes. We calculated the rates and trends of hospitalization for PBC per 100,000 US population among each gender (males and females) and racial categories (Whites, Blacks, Hispanics and other racial minorities), and measured the predictors of hospitalization, and of mortality, charges and length of stay (LOS) among PBC hospitalizations. RESULT: There were 8460 (weighted: 41,191) PBC hospitalizations between 2007 and 2014. The mean national PBC hospitalization rate was 2.2 cases per 100,000 population (2.2/100,000), increasing from 1.7/100,000 (2007) to 2.5/100,000 (2014). From 2007 to 2014, the in-hospital mortality and LOS were unchanged while the charges increased from $65,993 to $73,093 ($225 million to $447 million overall expenses). Compared to Whites, the PBC hospitalization rate was 12% higher among Hispanics (RR: 1.12 [1.09-1.16]), 53% lower in Blacks (RR: 0.47 [0.45-0.49]) and 5% lower among other racial minorities (0.95 [0.91-0.99]). The rate was higher among females (RR:4.02 [3.93-4.12]) compared to males. On multivariate analysis, Blacks and other racial minorities, respectively, had higher odds of mortality (AOR: 1.47 [1.03-2.10] and 1.33 [0.96-1.84]), while other racial minorities had longer LOS (7.0 vs. 5.6 days) and higher hospital charges ($48,984 vs. $41,495) when compared to Whites. CONCLUSION: The hospitalization rate and burden of PBC in the USA have increased disproportionately among females and Hispanics with higher mortality in Blacks.
