Background: Approximately one in eight people live with mental health difficulties, with onset commonly occurring in youth. It is critical to ensure care addresses all aspects of health, including physical health and sexual wellbeing needs, to achieve positive recovery outcomes. Connecting primary and secondary healthcare providers and service users through shared models of care is a critical aspect of this. The objectives of this scoping review will be to 1) identify and describe the implementation of shared models of care which address the mental health of young people and their physical health and/or sexual wellbeing needs, and 2) identify the determinants of implementing these models of care.

Protocol: Following Joanna Briggs Institute guidelines, studies will be included if they describe shared models of care for young people (aged 10-25) in any healthcare setting, specifically addressing mental health and physical health or sexual wellbeing needs. The review will employ the Consolidated Framework for Implementation Research (CFIR) to organise and assess findings. A librarian developed the search strategy, which will be applied to Web of Science, Medline, Embase, CINAHL, and PsycINFO databases. Two independent reviewers will screen titles, abstracts and full texts, followed by data extraction and critical appraisal of included studies. Discrepancies at all stages will be resolved through discussion or by a third reviewer. Screening results will be summarised in a PRISMA flow diagram. Narrative summaries, supported by tables and figures where applicable, will address the review's objectives. Findings will undergo thematic analysis, with implementation determinants mapped deductively to CFIR.

Discussion: Findings will inform the adaptation of implementation strategies to support the implementation of policy for improving healthcare delivery to young people with mental health difficulties.

背景： 大约每八个人中就有一人生活在心理健康困难之中，这些困难通常在青年时期开始出现。确保护理涵盖所有健康方面，包括身体健康和性健康需求，以实现积极的康复结果至关重要。通过共享照护模式将初级和二级医疗保健提供者和服务使用者连接起来是这一过程中的关键部分。本系统评价的目标是1）识别并描述实施共享照护模式的情况，这些模式针对青年人的心理健康及其身体或性健康的需要，2）确定实施这些照护模型的因素。

方案： 根据Joanna Briggs Institute的指导原则，如果研究描述了在任何医疗保健环境中为10-25岁年轻人（特别是涉及心理健康和身体或性健康需求）实施共享照护模式，则会被纳入。该评价将使用实施研究综合框架（CFIR）来组织和评估发现。一位图书馆员开发了搜索策略，并将其应用于Web of Science、Medline、Embase、CINAHL 和 PsycINFO 数据库。两位独立评审人员将筛选标题、摘要和全文，随后进行数据提取和包含的研究的质量评价。在所有阶段出现的分歧都将通过讨论或由第三方评审员解决。筛选结果将以PRISMA流程图总结。以叙述性概要形式回答评价目标，并根据适用情况辅以表格和图表。研究发现将经过主题分析，并且实施因素将被推论地映射到CFIR。

讨论： 该研究结果将为改进心理健康困难青年人的医疗服务交付政策制定适应性实施策略提供信息。
