Goals:
We described the temporal trend of substance use disorder (SUD) and SUD subtypes among patients hospitalized with inflammatory bowel disease (IBD), accounting for readmissions within the calendar year.
Background:
One in six patients with IBD is estimated to have a concomitant SUD. SUD has had mounting morbidity and mortality rates since 2010 and has been shown to adversely affect IBD activity.
Study:
We performed a retrospective analysis of patients hospitalized at least once with IBD from 2010 through 2020 using the Nationwide Readmissions Database. Multivariable logistic regression analysis evaluated associations between SUD and age, sex, insurance type, income for the ZIP Code, and geographic region.
Results:
Of 2,532,450 patients hospitalized with IBD, 26.5% and 17.0% involved SUD in Crohn's disease (CD) and ulcerative colitis (UC), respectively. Between 2010 and 2020, the prevalence of patients with SUD increased from 23.8% to 27.9% in CD (P trend <0.001) and 14.2% to 19.4% in UC (P trend <0.001). Rates of alcohol, opioid, and cannabis use disorders increased (P trend <0.001 for all). Patients with SUD were more likely to be male [CD: OR: 1.26; 95% CI: 1.24-1.27; UC: 1.34, (1.31-1.36)], have Medicaid insurance compared with Medicare [CD: 1.59, (1.55-1.63); UC: 1.84, (1.78-1.90)], and be in a lower income quartile [lowest to highest quartile, CD: 1.54, (1.51-1.58); UC: 1.56, (1.52-1.61)].
Conclusions:
SUD among IBD patients continued to increase over time, with the predominant substances used shifting from alcohol to opioids and cannabis. Rates of SUD among patients hospitalized with CD were consistently higher than those with UC or with non-IBD-related hospitalizations.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
