Trauma-Informed Approaches in the Context of Cancer Care in Canada and the United States: A Scoping Review.

Cancer is predominantly understood as a physical condition, but the experience of cancer is often psychologically challenging and has potential to be traumatic. Some people also experience re-traumatization during cancer because of previous, non-cancer-related trauma, such as intimate partner violence or adverse childhood experiences. A trauma-informed approach to care (TIC) has potential to enhance care and outcomes; however, literature regarding cancer-related TIC is limited. Accordingly, the objective of this scoping review was to identify what is known from existing literature about trauma-informed approaches to cancer care in Canada and the United States. A scoping review (using Arksey and O'Malley's (2005) framework) was conducted. The PsycINFO, CINAHL, MEDLINE (Ovid), Embase (Ovid), and Scopus databases, key journals, organizations, and reference lists were searched in February 2022. In total, 124 sources met the review criteria and 13 were included in the final review. Analysis included a basic descriptive summary and deductive thematic analysis using conceptual categories. Theorizations, applications, effectiveness, and feasibility of TIC were compiled, and gaps in TIC and recommendations for TIC were identified. TIC appeared to be growing in popularity and promising for improving cancer outcomes; however, gaps in the theorization, effectiveness, and feasibility of TIC persisted. Many recommendations for the application of TIC were not issued based on a strong body of evidence due to a lack of available literature. Further research is required to develop evidence-based recommendations regarding TIC related to cancer. A systematic review and meta-analysis would be warranted upon literature proliferation.
