What this trial studies

This multicenter quasi-experimental pre-test/post-test study will implement a co-designed transition program at two Belgian hospitals (Ghent University Hospital and University Hospital Antwerp) and compare it to usual care. About 150 adolescents aged 17–18 with type 1 diabetes, asthma, or obesity will be recruited, with the intervention delivered over 9–15 months and the control group followed under usual care. Outcomes include patient-reported health measures, experiences of patients and healthcare providers with implementation, and cost-effectiveness, measured at baseline, at transfer, and four months after transfer. The intervention comprises staged elements such as a transition consultation, an independent visit, and structured planning to support self-management and handover to adult services.

Who should consider this trial

Good fit: Ideal candidates are Dutch-speaking 17- to 18-year-olds with type 1 diabetes, asthma, or obesity who had at least one pediatric outpatient visit at one of the participating hospitals in the past year and plan to transfer to adult care within 12 months.

Not a fit: Patients with severe mental, cognitive, or neurological problems (who are excluded), non-Dutch speakers, those not followed at the participating hospitals, or those not transferring within the next year are unlikely to benefit from this program.

Why it matters

Potential benefit: If successful, the program could make transfers to adult care smoother, improve self-management and adherence, and reduce downstream complications and costs.

How similar studies have performed: Previous studies of structured transition programs have shown improvements in self-management and adherence for adolescents, but broad implementation and long-term evidence remain limited.
