409 Effect of Social Determinants of Health on Post-Discharge Adverse Outcomes After Surgical Resection of Meningioma

Abstract

INTRODUCTION: Understanding the role of social determinants of health (SDoH) is critical in informing preoperative care and postoperative follow-up for meningioma patients undergoing surgery. METHODS: A retrospective cohort study of adults presenting for meningioma resection from 1999-2020 was conducted. Primary outcomes included recurrence, readmission, and LTF (6-month and total). The main exposure of interest was Area Deprivation Index (ADI), a composite score of socioeconomic disadvantages. Additional SDoH factors analyzed included drive time to the hospital, insurance, and race. Multivariable logistic regression analyses for LTF and Cox regression for recurrence- and readmission-free survival were conducted. Covariates included age, WHO grade, and extent of resection. RESULTS: In total, 736 patients were included. Recurrence was observed in 90 patients, and 99 patients were readmitted following discharge. 121 patients missed initial and 6-month follow-up, but 107 of those eventually followed-up after six months. Fourteen patients were entirely LTF. ADI (OR = 1.11 per 10-point increase, 95% CI 1.02-1.21, p = 0.017) and drive time (OR = 1.03 per 30-minute increase, 95% CI 1-1.06, p = 0.022) predicted 6-month LTF. Drive time predicted complete LTF (OR = 1.04 per 30-minute increase, 95% CI 1-1.07, p = 0.017). Medicare/Military insurance predicted lower recurrence risk (HR = 0.43, 95% CI 0.23-0.81, p = 0.009) and higher readmission risk (HR = 2.00, 95% CI 1.17-3.41, p = 0.011). Other SDoH factors were not associated with recurrence or readmission. Lower WHO grade predicted lower recurrence risk (HR = 0.5, 95% CI 0.33-0.78, p = 0.002), while age (HR = 0.75 per 10-year increase, 95% CI 0.62-0.89, p < 0.001) and gross total resection (HR = 0.56, 95% CI 0.35-0.9, p = 0.016) predicted lower readmission risk. CONCLUSIONS: Socioeconomically disadvantaged neighborhoods and further distance from the hospital were barriers to follow-up after meningioma resection. Other SDoH associated with readmission and recurrence are reported. Individualized follow-up plans should consider these SDoH to ensure care continuity and improve outcomes.
