Abstract

Introduction: Social determinants of health have been shown to influence the health and outcomes of pediatric patients. Adolescent idiopathic scoliosis (AIS) may be particularly sensitive to such factors as early diagnosis and treatment can obviate the need for surgical intervention. The purpose of this study was to analyze the effect that social determinants of health have on the severity of AIS at presentation and at the time of surgery.

Methods: A retrospective review was conducted for consecutive patients who underwent posterior spinal fusion for AIS from 2020 to 2022. Demographic data was collected, while insurance status (private vs. public) and childhood opportunity index (COI) categories (LOW vs. HIGH) were used as a proxy for socioeconomic status. Curve magnitude at the initial presentation and at the latest preoperative visit were recorded with a threshold of 25 to 40 degrees considered within the bracing range. Univariate and multivariate analysis was done to compare differences between subgroups as appropriate.

Results: A total of 180 patients with mean initial and preoperative major curve angles of 48 and 60 degrees were included. Statistically significant differences in race and insurance types were appreciated, with the LOW COI group having a higher proportion of underrepresented minority and publicly insured patients than the HIGH COI group ( P <0.001). Patients within the LOW COI group presented with an initial curve that was, on average, 6 degrees more severe than those within the HIGH group ( P =0.009) and a preoperative curve that was 4 degrees larger than those within the HIGH group ( P =0.015). Similarly, only 13% of patients within the LOW COI group presented with curves within the bracing threshold, compared with 31% in the HIGH COI group ( P =0.009).

Conclusion: Socioeconomic status plays a significant role in the severity of AIS. Specifically, patients with lower COI tend to present with curve magnitudes beyond what is responsive to nonsurgical treatment, leading to larger curves at the time of surgery. Future work should focus on addressing social inequalities to optimize the treatment and outcomes of AIS patients.

Level of evidence: Level III- Retrospective Comparative Study.
