Building Bridges: Developing and Implementing a New Transition to Adult Care Program for Youth with Complex Healthcare Needs at a Canadian Children’s Hospital

<b>Background/Objectives</b>: Transitioning from pediatric to adult services can be challenging for youth with complex chronic health conditions, especially those with multi-morbidity. These youth often require extra coordination and support during this phase of their healthcare journey. Building upon existing provincial and national initiatives for transitions from pediatric to adult healthcare services, we have developed a hospital-wide program within one of Canada's largest children's hospitals that incorporates an integrated care model aimed at better serving these patients and improving outcomes. <b>Methods</b>: Guided by provincial quality standards, an environmental scan and knowledge user engagement were conducted to develop the program, followed by an implementation phase, where the model was piloted. Ongoing learnings from the pilot continue to inform program implementation and evaluation. <b>Results</b>: The Transition to Adult Care (TAC) program offers disease-agnostic care to youth with complex needs for 1-3 years, including 1-year post-transfer, addressing the fragmentation of care across multiple services, organizations and providers. Our interdisciplinary team works in partnership with youth and caregivers to deliver transition navigation, easing the burden on patients and families by tailoring transition supports to each individual youth and caregiver. Preliminary data from the pilot revealed a lack of awareness about transition resources and timelines; however, with early engagement and flexible support beyond age 18, youth were able to complete their transition successfully. <b>Conclusions:</b> The TAC program demonstrates a systems-level approach to improving transition to adult care for youth with complex health needs by integrating individualized support, cross-sectoral collaboration, and continuous quality improvement. Early engagement, flexible post-transfer support, and close partnership with youth, caregivers, and providers are key to facilitating transition. These learnings can inform broader implementation efforts and help address persistent gaps in transitional care across healthcare systems.
