Dutch hospital data reveals hidden patterns in IBD treatment
NCT ID NCT07682038
First seen Jul 02, 2026 · Last updated Jul 02, 2026
Summary
This study looks at medical records from thousands of adults with Crohn's disease or ulcerative colitis treated in Dutch hospitals between 2018 and 2026. Researchers will analyze which treatments patients receive, how often they switch therapies, and how the disease affects other parts of the body. The goal is to understand real-world care and costs, which may help improve future treatment decisions.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this research could help doctors better understand which treatments work best for different patients and improve care planning for inflammatory bowel disease.
- What could go wrong
- This is an observational study that looks at past data, so it cannot prove cause and effect. Results may not apply to patients outside the Netherlands.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adult patients (≥18 years of age) who required secondary (hospital) care after January 2018 with a confirmed diagnosis of CD or UC, defined by at least one ICD-10 diagnosis code for CD or UC (K50, K51, K52). Index date confirmation: the index date is defined as the first date of confirmed CD or UC diagnosis, requiring at least one healthcare encounter for CD or UC AND at least one prescription or dispensing record for any CD or UC-related medication within the observational period. Exclusion Criteria: * Patients who have formally objected to the use of their hospital data for scientific research purposes. Objections are recorded by the treating hospital in the DBC administrative system and automatically transferred to the research dataset, ensuring automatic exclusion from all analyses.
