Novel Characterization of Socioecological Determinants of Health in Rural Alabama.

Introduction: Socioecological determinants of health (SEDOHs) influence disparities in surgical outcomes. However, SEDOHs are challenging to measure, limiting our ability to address disparities. Using a validated survey (SEDOH-88), we assessed SEDOHs in three rural communities in Alabama. We hypothesized that SEDOHs would vary significantly across sites but measuring them would be acceptable and feasible.
Materials and Methods: This was a retrospective review of a prospectively maintained database involving surgical patients who completed the SEDOH-88 and a secondary survey assessing it's acceptability or feasibility from August 2021 to July 2023. Included patients underwent endoscopic, minimally invasive, or open surgery at three rural hospitals: Demopolis (DM), Alexander City (AC), and Greenville (GV).
Results: The 107 participants comprised 48 (44.9%) from DM, 27 (25.2%) from AC, and 32 (29.9%) from GV, respectively. The median age was 64 y, and 65.6% were female. When comparing DM to AC and GV by individual factors, DM had the largest Black population (78.7 versus 22.2 versus 48.3%, P < 0.001) and more often required help reading hospital materials (20.5 versus 3.7 versus 10.3%, P = 0.007). When comparing DM to AC and GV by structural and environmental factors, DM had more Medicaid enrollees (27.3 versus 3.7 versus 6.9%, P = 0.033) and lacked fresh produce (18.2 versus 25.9 versus 39.3%, P = 0.033) and internet access (63.6 versus 100.0 versus 86.2%, P < 0.001). The SEDOH-88 had an overall 90.9% positive acceptability and feasibility score.
Conclusions: SEDOHs varied significantly across rural communities regarding individual (race or health literacy), structural (insurance), and environmental-level factors (nutritious food or internet access). The high acceptability and feasibility of the SEDOH-88 shows it's potential utility in identifying targets for future disparity-reducing interventions.
