Social determinants of health and health outcomes in older cancer survivors.

Purpose of the review: Today, two-thirds of all cancer survivors are at least 65 years old. Older cancer survivors have complex care needs, and addressing their social determinants of health (SDoH) is critical for improving and managing survivorship outcomes for this uniquely vulnerable population, yet research specifically examining these associations remains limited and emergent. To this end, we describe the emergent body of evidence on the associations between SDoH domains and older cancer survivors' outcomes.

Recent findings: Despite the limited investigations of SDoH on the health outcomes of older cancer survivors, there were measures representing all domains of SDoH - health care access and quality, education access and quality, neighborhood and built environment, social and community context, and economic stability. We reviewed another determinant, Digital Environment and Engagement, as they are highly relevant to older cancer survivors' care. Studies primarily investigated outcomes such as the use of or delays in treatment and variables related to care coordination. Generally, poorer access to resources such as income, social networks, and quality health care facilities predicted poorer health outcomes.

Summary: We reviewed studies that revealed that SDoH significantly impacts older cancer survivors' health outcomes. Our description informs future interventions and policies to improve their care.
