ABSTRACT: Background: Disparities in neurosurgical care have emerged as an area of interest when considering the impact of social determinants on access to health care. Decompression via anterior cervical discectomy and fusion (ACDF) for cervical stenosis (CS) may prevent progression towards debilitating complications that may severely compromise one's quality of life. This retrospective database analysis aims to elucidate demographic and socioeconomic trends in ACDF provision and outcomes of CS-related pathologies. Methods: The Healthcare Cost and Utilization Project National Inpatient Sample database was queried between 2016 and 2019 using International Classification of Diseases 10th edition codes for patients undergoing ACDF as a treatment for spinal cord and nerve root compression. Baseline demographics and inpatient stay measures were analyzed. Results: Patients of White race were significantly less likely to present with manifestations of CS such as myelopathy, plegia, and bowel-bladder dysfunction. Meanwhile, Black patients and Hispanic patients were significantly more likely to experience these impairments representative of the more severe stages of the degenerative spine disease process. White race conferred a lesser risk of complications such as tracheostomy, pneumonia, and acute kidney injury in comparison to non-white race. Insurance by Medicaid and Medicare conferred significant risks in terms of more advanced disease prior to intervention and negative inpatient. Patients in the highest quartile of median income consistently fared better than patients in the lowest quartile across almost every aspect ranging from degree of progression at initial presentation to incidence of complications to healthcare resource utilization. All outcomes for patients age > 65 were worse than patients who were younger at the time of the intervention. Conclusions: Significant disparities exist in the trajectory of CS and the risks associated with ACDF amongst various demographic cohorts. The differences between patient populations may be reflective of a larger additive burden for certain populations, especially when considering patients’ intersectionality.
