Exploring the Social Determinants of Health Outcomes for Adults with Low Back Pain or Spinal Cord Injury and Persistent Pain: A Mixed Methods Study.

Developing a greater understanding of the social and environmental factors that are related to differential outcomes for individuals who experience persistent pain and disability is important for achieving health equity. In this study, we aimed to develop insights into the role of the social determinants of health (SDH) in care experiences and health status for socio-economically disadvantaged adults who experience persistent low back pain or persistent pain following spinal cord injury. Our objectives were to investigate 1) relationships between the SDH and health outcomes, 2) care experiences, and 3) perceived barriers and facilitators to optimal pain care. We conducted a mixed-methods convergent parallel study involving an online survey and semistructured interviews. We analyzed the data from each method separately and integrated the findings. One hundred sixty-four adults completed the survey and 17 adults completed the semistructured interviews. We found large or moderate-sized correlations between greater selfreported social isolation and poorer health outcomes. Experiencing a higher number of adverse SDH was moderately correlated with lower quality of life and was significantly correlated with all other outcomes. We generated 5 themes from the qualitative analysis: active strategies are important for well-being; low agency; facilitators of optimal care; barriers to optimal care; and health inequities, and derived meta-inferences that highlight the complex inter-relationships between the SDH and health outcomes in this cohort. The findings of our study can importantly inform endeavors to improve equity of pain care for adults with low back pain or spinal cord injury and persistent pain. PERSPECTIVE: This study illustrates the complex interplay between adverse social determinants of health and poorer health status for adults with persistent pain and provides evidence to support the important role of social isolation. Developing an understanding of the life-contexts of those seeking care is a vital step towards addressing health inequities.
