Abstract
OBJECTIVE: Inflammatory bowel disease (IBD) patients with Clostridium difficile co-infection (CDCI) have an increased risk of morbidity and mortality. We aim to evaluate the impact of CDCI on in-hospital outcomes among adults with IBD hospitalized in the USA.
PATIENTS AND METHODS: Using the 2007-2013 Nationwide Inpatient Sample, hospitalizations among US adults with Crohn's disease (CD), ulcerative colitis (UC) and CDCI were identified using ICD-9 coding. Hospital charges, hospital length of stay (LOS), and in-hospital mortality was stratified by CD and UC and compared using χ-testing and Student's t-test. Predictors of hospital charges, LOS, and in-hospital mortality were evaluated with multivariate regression models and were adjusted for age, sex, race/ethnicity, year, insurance status, hospital characteristics, and CDCI.
RESULTS: Among 224 500 IBD hospitalizations (174 629 CD and 49 871 UC), overall prevalence of CDCI was 1.22% in CD and 3.41% in UC. On multivariate linear regression, CDCI was associated with longer LOS among CD [coefficient: 5.30, 95% confidence interval (CI): 4.61-5.99, P<0.001] and UC (coefficient 4.08, 95% CI: 3.54-4.62, P<0.001). Higher hospital charges associated with CDCI were seen among CD (coefficient: $35 720, 95% CI: $30 041-$41 399, P<0.001) and UC (coefficient: $26 009, 95% CI: $20 970-$31 046, P<0.001). On multivariate logistic regression, CDCI was associated with greater risk of in-hospital mortality (CD: odds ratio: 2.74, 95% CI: 1.94-3.87, P<0.001; UC: OR: 5.50, 95% CI: 3.83-7.89, P<0.001).
CONCLUSION: Among US adults with CD and UC related hospitalizations, CDCI is associated with significantly greater in-hospital mortality and greater healthcare utilization.
