The influence of race and hospital environment on the care of patients with cervical spine fractures

Abstract

BackgroundThe influence of non-white race on outcomes following orthopedic injury has been described in the past. The impact of such factors on hospital processes and quality of care after spinal trauma is less well understood. Study DesignA cohort control study using the Massachusetts Statewide Inpatient Dataset (2003–2010) was used as the study design. PurposeThis study aimed to determine whether (1) hospital processes and quality of care associated with the treatment of cervical spine fractures was significantly altered by non-white race and (2) whether findings were different among those treated at academic medical centers (AMCs). SampleThe study comprised 10,841 patients. OutcomesSurgical rate, postoperative morbidity, mortality, and length of stay (LOS) were the outcome measures. MethodsBaseline differences between cohorts were evaluated using chi-square or Wilcoxon rank sum tests. Logistic and negative binomial regression techniques were used to adjust for confounders, including whether a surgical intervention was performed. Subset analyses were performed to evaluate whether findings were different for individuals treated at AMCs. ResultsThe rate of surgical intervention was not significantly different between non-whites and whites (odds ratio [OR] 0.92, 95% confidence interval [CI] 0.82–1.04). LOS (regression coefficient [RC] 0.18, 95% CI 0.13–0.23), mortality (OR 1.49, 95% CI 1.20–1.85), and complications (OR 1.17, 95% CI 1.02–1.33) were significantly increased among non-white patients. These findings were largely preserved among those treated at AMCs. ConclusionsOur results reinforce the fact that efforts at universal access to care may be insufficient to reduce differences in care among minority patients following cervical trauma. Future mixed-methods research is necessary to more effectively evaluate the etiologies behind health-care disparities associated with race in different health-care environments. Level of EvidenceThe level of evidence is Level III, prognostic study.
