Abstract

Purpose: There are scarce data describing the outcomes of hospitalized patients admitted with inflammatory bowel disease (IBD) stratified by race. In this retrospective cohort study, we evaluated the difference in outcomes between adult white and black patients hospitalized with a principal diagnosis of inflammatory bowel disease.

Methods: Data were obtained from the 2016 and 2017 National Inpatient Sample (NIS) database. Our primary outcome was inpatient mortality while the secondary outcomes were hospital length of stay (LOS), total hospital charges (THC), red blood cell (RBC) transfusion, diagnosis of bowel perforation, and severe sepsis with septic shock. We conducted the analysis using STATA software. We used propensity-matched multivariate regression analysis to adjust for potential confounders.

Results: Among 71 million hospital hospitalizations, we found 177,574 hospitalizations with a principal diagnosis of IBD, with 24,635 (13.9%) for black patients, 124,899 (70.3%) for white patients, and 28,040 (15.8%) were for others. There was no significant difference in inpatient mortality for black vs white patients. Among secondary outcomes, white compared to black patients had increased odds of having a diagnosis of bowel perforation when admitted with a diagnosis of IBD while there was no difference in the odds of developing septic shock. White patients admitted with a diagnosis of UC were also found to have increased total LOS and THC.

Conclusion: White patients hospitalized with a principal diagnosis of IBD had no difference in inpatient mortality or septic shock but had worse outcomes such as increased odds of bowel perforation compared to black patients.
