Disease, treatment patterns, and healthcare use in Korean children with inflammatory bowel diseases

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

Observational Janssen Korea, Ltd., Korea · NCT07520747

This project will see how Korean children with Crohn's disease or ulcerative colitis are diagnosed, treated as they grow, and how often they use healthcare services.

What this trial studies

This observational database analysis uses Korean medical records to estimate how many children develop and live with Crohn's disease and ulcerative colitis, with results stratified by age. Cases are identified using ICD-10 codes (K50.x for CD, K51.x for UC), rare disease registry codes (V130/V131), and medication records, requiring at least two outpatient or one inpatient diagnosis plus an IBD medication prescription during the index period. The study tracks longitudinal treatment patterns (including 5-ASA, exclusive enteral nutrition, corticosteroids, immunomodulators, and biologics), how regimens change as children age, and healthcare utilization and costs over several years. Data analysis is performed using records available to Sungkyunkwan University and sponsored by Janssen Korea.

Who should consider this trial

Good fit: Children in Korea diagnosed with Crohn's disease or ulcerative colitis whose care appears in national medical records and who have the required diagnostic codes and at least one IBD medication prescription are eligible.

Not a fit: Children without documented ICD-10 codes for CD or UC, without IBD medication prescriptions, or whose care occurs outside the covered Korean databases are unlikely to be included or benefit.

Why it matters

Potential benefit: If successful, the findings could help clinicians and policymakers improve treatment pathways and resource planning for children with IBD in Korea.

How similar studies have performed: Similar national database analyses in other countries have reliably described pediatric IBD incidence, treatment trends, and costs, so this method is well established rather than novel.
