Impact of Racial/Ethnic Disparities on Patient Reported Outcomes Following Cervical Spine Surgery: QOD Analysis.

STUDY DESIGN:Retrospective analysis of data from the cervical module of a national spine registry, the Quality Outcomes Database (QOD). OBJECTIVE:To examine the association of race and ethnicity with patient-reported outcome measures (PROMs) at 1 year after cervical spine surgery. SUMMARY OF BACKGROUND DATA:Evidence suggests that Black individuals are 39% to 44% more likely to have postoperative complications and prolonged length of stay after cervical spine surgery compared to Whites. The long-term recovery assessed with PROMs after cervical spine surgery among Black, Hispanic and other non-Hispanic groups (i.e., Asian) remains unclear. METHODS:PROMs were used to assess disability (NDI) and neck/arm pain preoperatively and 1-year postoperative. Primary outcomes were disability and pain, and not being satisfied from pre-operative to 12-months after surgery. Multivariable logistic and proportional odds regression analyses were used to determine the association of racial/ethnic groups (Hispanic, non-Hispanic White (NHW), non-Hispanic Black (NHB), and non-Hispanic Asian (NHA)) with outcomes after covariate adjustment and to compute the odds of each racial/ethnic group achieving MCID 1-year postoperatively. RESULTS:Of the 14,429 participants, all had significant reductions in pain and disability, and 87% were satisfied at 1-year follow-up. Hispanic and NHB patients had higher odds of not being satisfied (40% and 80%) and having worse pain outcomes (30% to 70%) compared to NHW. NHB had 50% higher odds of worse disability scores compared to NHW. NHA reported similar disability and neck pain outcomes compared to NHW. CONCLUSIONS:Hispanic and non-Hispanic Black patients had worse patient-reported outcomes 1-year after cervical spine surgery compared to non-Hispanic White individuals, even after adjusting for potential confounders, yet there was no difference in disability and neck pain outcomes reported for non-Hispanic Asian patients. This study highlights the need to address inherent racial/ethnic disparities in recovery trajectories following cervical spine surgery. LEVEL OF EVIDENCE:3.
