Co-designed healthcare transition interventions for adolescents and young adults with chronic conditions: a scoping review.

Purpose: To determine the scope of published literature on healthcare transition (HCT) interventions that have been co-designed with adolescents and young adults with chronic conditions, and to undertake feasibility assessments.

Methods: Using Scopus, CINAHL, Medline-Ovid, Cochrane and PsycINFO databases, publications that included a HCT intervention to support paediatric to adult healthcare transition were included. Study location, design, population, description of the intervention, co-design methods, feasibility evidenced using Bowen and colleagues' framework, and outcome measures were extracted for review.

Results: A total of 21 studies were included, relating to 17 co-designed HCT interventions that ranged across multiple medical specialties. There was no standard HCT intervention; characteristics, format and delivery mode varied. Only three studies reported a detailed description of the co-design method(s) used and none reported on the facilitators or barriers. Among the studies, five of Bowen and colleagues' eight dimensions of feasibility were measured.

Conclusions: Despite the co-design process being neither described or evaluated extensively, all co-designed HCT interventions included in this review were considered to be feasible. Nevertheless, HCT interventions varied in their format and delivery method making it difficult to compare between them. Furthermore, interventions were often condition-specific and not representative of the extensive range of chronic conditions.Implications for RehabilitationHealthcare transition interventions can improve adherence to care, health outcomes, ongoing rehabilitation, and quality of life of adolescents and young adults with chronic conditions.Healthcare transition interventions should maximise long-term functioning and prioritise rehabilitation aimed at enhancing independence and self-management skills, while reducing hospitalisations.The engagement of individuals with lived experience in the co-design of interventions has been strongly advocated as it brings unique knowledge and experience to the research process.Minimal attention has been given to the involvement of adolescents and young adults with chronic conditions in the development of healthcare transition interventions, however, healthcare transition interventions co-designed with adolescents and young adults with chronic conditions are both feasible and acceptable.
