Introduction: Few studies have evaluated if there are regional differences in inflammatory bowel diseases (IBD) in the United States and contemporary data on the sociodemographic characteristics of patients with IBD are lacking. We investigated the contemporary sociodemographic and regional differences in hospitalized patients with IBD.
Methods: The National Inpatient Sample, years 2018-2019, was queried to identify hospitalizations in patients with IBD using ICD-10 codes K50 for Crohn’s disease (CD) and K51 for ulcerative colitis (UC). We studied age, sex, racial distribution, geographic region in the US, income and health insurance status of this IBD population in comparison to patients without any form of IBD, and evaluated for differences between patients with UC and CD. Rao-Scott chi square test and Wilcoxon rank sum test were used for unadjusted comparisons.
Results: Of 674,505 hospitalizations in patients with IBD, the majority were in patients with CD (62.1%). Median patient age was 55 years (interquartile range [IQR], 37-70) and 56.2% admissions were in females. Patients with IBD were more likely of White race (76.6%) compared to the non-IBD population (64.6%), and less likely to be of other racial groups. Most admissions in patients with IBD were in the Southern US (36.6%) followed by Midwest (24.9%), Northeast (21.3%), and Western US (17.2%). Income status of the IBD patients was equally distributed among 4 quartiles whereas the general population tended to be more in the lower quartiles. Compared with the non-IBD population, patients with IBD were more likely to have private insurance (39% vs 32%; P< 0.01) and less likely to have Medicaid. Compared with patients with UC, patients with CD were younger (median age 59 [38-72] years vs 52 [36-67] years; P< 0.01) and more likely female (57.6% vs 53.9%; P< 0.01). Only subtle differences were noted between the IBD subtypes for other sociodemographic and racial characteristics studied (TABLE). Findings were similar between years 2018 and 2019.
Discussion: Patients with IBD had a substantial number of hospitalizations in the contemporary period with close to 2/3rds in patients with CD. Hospitalized IBD patients are more commonly white and female. A few prior studies reported that the prevalence of IBD was higher in northeastern US, however we noted more hospitalizations occurred in the Southern US. These findings should prompt further research to identify measures to improve healthcare access and delivery throughout the US.
