Antidepressant medication use in Inflammatory Bowel Disease: a nationally representative population-based study

Area of Science:

• Gastroenterology
• Psychiatry
• Pharmacoepidemiology

Background:

• Inflammatory bowel disease (IBD) is associated with high rates of depression and anxiety.
• Antidepressant use patterns in IBD patients remain understudied.

Purpose of the Study:

• To examine temporal trends in antidepressant use among IBD patients.
• To assess antidepressant initiation rates and guideline adherence in IBD.
• To identify factors associated with antidepressant undertreatment in IBD.

Main Methods:

• A population-based cohort study using the Clinical Practice Research Datalink (2004-2016).
• Included 14,525 incident IBD cases and 58,027 matched controls.
• Used Cox and logistic regression to analyze antidepressant use and undertreatment risks.

Main Results:

• Antidepressant use in IBD patients increased by 51% from 2004-2016.
• IBD patients were 34% more likely to initiate antidepressants post-diagnosis.
• 67% of IBD patients on antidepressants received treatment shorter than recommended, with 34% treated for ≤1 month.
• Younger adults (18-24) and socioeconomically deprived individuals showed higher rates of early discontinuation.

Conclusions:

• IBD patients have increased antidepressant initiation post-diagnosis but often experience undertreatment.
• The majority of IBD patients do not adhere to recommended antidepressant treatment durations.
• Improved integrated care services are crucial for managing psychiatric comorbidities in IBD.
