Umbrella Reviews Conducted in an Oncology Healthcare Context Focusing on Supportive Care, Systems, and Models of Care: A Review of Umbrella Reviews.

[AIMS] Healthcare providers need access to evidence-based knowledge to deliver interventions effectively within clinical settings. This paper aims to provide an overview of umbrella reviews (URs) conducted in an oncology healthcare context. In this review, the oncology healthcare context relates to focusing on care delivery systems, supportive care, supportive care needs, and supportive care interventions, systems, and models of care for cancer survivorship care and support.

[METHODS] This overview followed the Preferred Reporting Items for Overviews of Reviews (PRIOR) statement. The literature search was performed in seven databases including PubMed, CINAHL, APA PsycArticles, APA PsycInfo, SocINDEX with Full Text, Embase, and Cochrane Database from 2012 to 2023. The search terms and eligibility criteria were organized around the PCC framework. The JBI Critical Appraisal Checklist for Systematic Reviews and Research Synthesis was used for quality assessment.

[RESULTS] Seventy-six umbrella reviews were included in this review. Only four reviews demonstrated low quality. Tables and bubble maps helped to outline the key findings of included URs. Recommendations to aid future studies and reviews were summarized into five overarching themes.

[CONCLUSIONS] In conclusion, we outlined the range and gaps in topics covered, as well as the key features of umbrella reviews examining oncological supportive care systems and models of care over the past decade. Future research should address the multidimensional nature and complexity of clinical implementation and methodological concerns; consider underrepresented populations and be more targeted to inform policy development.
