<p>The transition from pediatric to adult health care is often challenging for adolescents and young adults with sickle cell disease (SCD). Our study aimed to identify (1) measures of success for the transition to adult health care; and (2) barriers and facilitators to this process. We interviewed 13 SCD experts and asked them about their experiences caring for adolescents and young adults with SCD. Our interview guide was developed based on Social-Ecological Model of Adolescent and Young Adult Readiness to Transition framework, and interviews were coded using the constant comparative method. Our results showed that transition success was measured by health care utilization, quality of life, and continuation on a stable disease trajectory. We also found that barriers to transition include negative experiences in the emergency department, sociodemographic factors, and adolescent skills. Facilitators include a positive relationship with the provider, family support, and developmental maturity. Success in SCD transition is primarily determined by the patients' quality of relationships with their parents and providers and their developmental maturity and skills. Understanding these concepts will aid in the development of future evidence-based transition care models.</p>

<p><strong>BACKGROUND: </strong>For adolescents and young adults (AYA) with inflammatory bowel disease (IBD), the transition from pediatric to adult care is often challenging and associated with gaps in care. Our study objectives were to (1) identify outcomes for evaluating transition success and (2) elicit the major barriers and facilitators of successful transition.</p>

<p><strong>METHODS: </strong>We interviewed pediatric and adult IBD providers from across the United States with experience caring for AYAs with IBD until thematic saturation was reached after 12 interviews. We elicited the participants' backgrounds, examples of successful and unsuccessful transition of AYAs for whom they cared, and recommendations for improving transition using the Social-Ecological Model of Adolescent and Young Adult Readiness to Transition framework. We coded interview transcripts using the constant comparative method and identified major themes.</p>

<p><strong>RESULTS: </strong>Participants reported evaluating transition success and failure using health care utilization outcomes (e.g., maintaining continuity with adult providers), health outcomes (e.g., stable symptoms), and quality of life outcomes (e.g., attending school). The patients' level of developmental maturity (i.e., ownership of care) was the most prominent determinant of transition outcomes. The style of parental involvement (i.e., helicopter parent versus optimally involved parent) and the degree of support by providers (e.g., care coordination) also influenced outcomes.</p>

<p><strong>CONCLUSIONS: </strong>IBD transition success is influenced by a complex interplay of patient developmental maturity, parenting style, and provider support. Multidisciplinary IBD care teams should aim to optimize these factors for each patient to increase the likelihood of a smooth transfer to adult care.</p>
