A Database Study of Disease, Treatment Patterns and Healthcare Use in Children With Inflammatory Bowel Diseases in Korea (Ped IBD Claims)

June 4, 2026 updated by: Janssen Korea, Ltd., Korea

Epidemiology, Treatment Patterns, and Healthcare Resource Utilization in Pediatric Patients Under 18 Years of Age With Inflammatory Bowel Diseases in Korea: A Claims Database Study

The purpose of this study is:

  • to find out out the number of children who develop crohn's disease (CD) and ulcerative colitis (UC) each year and are living with the disease and to see how this differs by age groups.
  • to understand how children of different age groups are treated over time and how their treatment changes as they grow.
  • to assess how often children use healthcare services and how much this costs for different age groups over several years.

CD and UC are long-term diseases that cause inflammation in intestine (part of digestive system) and develop ulcers.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Group 1: Newly and Previously Diagnosed Pediatric Inflammatory Bowel Disease (IBD) Participants
Participants, who have been either newly diagnosed or previously diagnosed with Crohn's disease (CD) or Ulcerative colitis (UC) will be enrolled. Data will be analyzed for epidemiology, baseline demographics and clinical characteristics, health care resource utilization profiles, and associated costs. Only newly diagnosed participants will be included in the analysis of longitudinal treatment patterns and incidence estimation. Only data available per routine clinical practice will be used in this study and will be de-identified and extracted from the health insurance review and assessment (HIRA) database.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
