Race and socioeconomic disparities persist in treatment and outcomes of patients with cervical spinal cord injuries: An analysis of the national inpatient sample from 2016 - 2020.

OBJECTIVE

Previous literature has described race and socioeconomic disparities in both treatment and outcomes following cervical spinal cord injuries (SCI). The goal of this study is to investigate the current state of parity in management and outcomes following SCI.

METHODS

We surveyed the National Inpatient Sample database (NIS) for patients admitted with primary diagnosis of cervical SCI. 49,320 patients were identified. Univariate and multivariate analyses were performed to evaluate racial and socioeconomic differences in SCI care and outcomes.

RESULTS

Compared to white patients, minority race was associated with a longer time from presentation to operative intervention (p < 0.001) and longer length of stay following admission for cervical SCI (16 vs 13 days, p < 0.001). Minority patients were more likely to have an unfavorable discharge (skilled nursing facility, against medical advice, death) status than white patients (p < 0.001). Patients in the bottom quartile of median household income were associated with more unfavorable discharges than the top two quartiles (p < 0.001). Patients with the lowest median household income quartile also had higher total costs than those in the top quartiles ($221,654 vs 191,723, p < 0.001). Black, Hispanic, and Asian/Pacific Islander incurred higher treatment costs than White patients.

CONCLUSION

Minority and lower socioeconomic status are independently associated with unfavorable discharge and LOS in cervical SCI. Furthermore, racial and economically disadvantaged groups have longer wait times from admission to surgical intervention. These disparities persist despite being highlighted by previous publications and increased societal awareness of healthcare inequities, necessitating further work to reach parity.
