IntroductionKyphoplasty is a minimally invasive treatment for chronic refractory pain secondary to spinal compression fracture. This study investigates racial and socioeconomic disparities in kyphoplasty among the Medicare population.Materials And MethodsThis study utilized data from the Medicare Limited Data Sets (LDS), a CMS administrative claims database. Patients aged 18 and older with ICD code consistent with spinal pathology and compression fractures were included. Outcome was defined as kyphoplasty by race and socioeconomic status (SES) with low SES defined by dual enrollment in Medicare/Medicaid.ResultsThere was a total of 215,502 patients gathered from CMS data, and 717 (0.33%) of these patients underwent kyphoplasty during the study period. Of these patients, 458 (63.8%) were female, the average age was 76.5 years old, 655 (91.3%) were White, 20 (2.7%) were Black, 9 (1.3%) were Hispanic, and 98 (13.7%) were Medicare/Medicaid dual eligible. White patients (32,317/157,177 [20.6%]) were less likely to be dual enrollment eligible in Medicare and Medicaid than Black (5407/13,522 [39.9%]), Hispanic (2833/3675 [77.1%]), Asian (2087/3312 [63.0%]), or North American Native patients (778/1578 [49.1%]). Multivariate regression (MVR) analysis was performed and showed that Blacks were less likely than Whites to have a kyphoplasty performed (OR 0.46 [95% CI: 0.29-0.72], p-value <0.001). Although Hispanics (OR 0.95 [0.49-1.86]), North American Native (OR 0.82 [0.3-2.19]), and unknown race had a decreased odd of undergoing kyphoplasty, it was not statistically significant.ConclusionOur study showed after adjustment for pertinent comorbidities, Medicare/Medicaid dual-eligible patients and Black patients were significantly less likely to receive kyphoplasty than White patients with Medicare.© 2023 World Institute of Pain.
