Objectives: This retrospective cohort of patients undergoing surgery from 2019 to 2023 evaluated the association between individual-level social drivers of health (SDoH) and postoperative outcomes (length of stay, 30-day mortality, 30-day readmission).
Methods: Patients from a multi-site health system who completed a SDoH questionnaire were categorized as high-risk or not high-risk across five SDoH domains (e.g., financial resources) and were stratified into 3 surgical cohorts (elective outpatient, inpatient and emergency surgery). Regression models, adjusted for potential confounders, assessed the association between SDoH and postoperative outcomes.
Results: Among 297,723 patients, 74% completed the SDoH questionnaire. High-risk transportation need was associated with higher unplanned 30-day readmission for all cohorts; for elective surgeries, high-risk transportation was also associated with higher mortality. The other SDoH domains were inconsistently associated with postoperative outcomes.
Conclusions: Individual-level SDoH, particularly transportation needs and financial strain, are linked to adverse postoperative surgical outcomes. Systematic SDoH interventions are crucial to addressing healthcare disparities.
