Abstract
In recent years, there has been a growing emphasis on understanding the relationship between individual-level social determinants of health, which include social risks and social needs, within the realm of cancer care delivery. Social risks include food insecurity, housing instability, and transportation barriers, leading to adverse health outcomes. These social risks become social needs when patients identify a desire for assistance in addressing them. As the number of cancer survivors increases and disparities in the burden of cancer persist, there is a critical need to focus efforts on ensuring all survivors experience high-quality and equitable care across the cancer continuum, from diagnosis to end-of-life care. To inform research activities and intervention development, we aim to summarize and describe cancer care delivery research focused on three social risk factors: food insecurity, housing insecurity, and transportation barriers. To achieve our research objectives, we conducted a scoping review using Covidence software to examine published research assessing and addressing housing insecurity, food insecurity, and transportation barriers among individuals diagnosed with cancer. Six databases were searched: PubMed, Scopus, Cochrane Library, CINAHL Plus, EMBASE, and PsycINFO. Inclusion criteria for this review included original research in English published between 2010 and 2023 that focused on cancer patients and survivors in the United States and included social risk factors and cancer care delivery data. Data selection and screening were performed in two phases: (1) title and abstract and (2) full text, which required two independent reviewers. Discrepancies and disagreements between the two reviewers for inclusion of studies were resolved through weekly discussions at team meetings. A data abstraction tool that contains nine general variable categories was developed. We identified 10,032 studies, of which 76 were duplicates, and 9,368 were irrelevant at the title and abstract levels. We are currently finishing the full-text screening for the 563 studies deemed potentially eligible for inclusion at the title abstract level. To date, 164 of the 335 studies screened have met our eligibility criteria. We will extract data from all eligible studies once the full-text screening is completed. Across eligible studies, transportation barriers (91.5%) were the most common social risk factor of focus, followed by studies focusing on food insecurity (6.7%) and housing insecurity (3.7%). Our scoping review findings will provide us with a wide spectrum of knowledge regarding the most prominent relationships between social risk factors and cancer care delivery, gaps in current work, and existing interventions targeting these efforts. The results of this work will enhance our understanding of how social-structural disadvantages influence cancer outcomes and inform the development of concerted efforts aimed at addressing the social factors contributing to the unequal burden of cancer among survivors.
