ObjectivesClinical communication needs of teenagers and young adults with cancer (TYACs) are increasingly recognised to differ significantly from younger children and older adults. We sought to understand who is present with TYACs, TYACs’ experiences of triadic communication and its impact. We generated three research questions to focus this review: (1) Who is present with TYACs in healthcare consultations/communication?, (2) What are TYACs’ experiences of communication with the supporter present? and (3) What is the impact of a TYAC’s supporter being present in the communication?DesignSystematic review with narrative synthesis.Data sourcesThe search was conducted across six databases: Medline, CINAHL, Embase, PsycINFO, Web of Science and AMED for all publications up to December 2023.Eligibility criteria for selecting studiesIncluded papers were empirical research published after 2005; participants had malignant disease, diagnosed aged 13–24 years (for over 50% of participants); the research addressed any area of clinical communication.Data extraction and synthesisThree independent reviewers undertook full-text screening. A review-specific data extraction form was used to record participant characteristics and methods from each included paper and results relevant to the three review questions.ResultsA total of 8480 studies were identified in the search, of which 36 fulfilled the inclusion criteria. We found that mothers were the most common supporter present in clinical communication encounters. TYACs’ experiences of triadic communication are paradoxical in nature—the supporter can help or hinder the involvement of the young person in care-related communication. Overall, young people are not included in clinical communication and decisions at their preferred level.ConclusionTriadic communication in TYACs’ care is common, complex and dynamic. Due to the degree of challenge and nuances raised, healthcare professionals need further training on effective triadic communication.PROSPERO registration numberCRD42022374528.
