30-day adverse outcomes, re-admissions and mortality following vertebroplasty/kyphoplasty

Abstract

ObjectivesDespite vertebral fractures being a common occurrence in elderly osteoporotic individuals, literature remains scant with regards to 30-day outcomes following vertebral augmentation for these injuries. We studied a national database of elderly osteoporotic patients who underwent vertebroplasty and kyphoplasty. Patients and methodsThe 2012–2014 ACS-NSQIP database was queried using CPT codes for vertebroplasty (22520, 22521 and 22522) and kyphoplasty (22523, 22524 and 22525). Patients undergoing concurrent spinal fusion and/or laminectomies/laminotomies/laminoplasties were removed from the study. Patients with missing data were also excluded from the study. ResultsFollowing inclusion/exclusion criteria, a total of 2433 patients were included in the study out of which 242(9.9%) underwent vertebroplasty and 2191(90.1%) underwent kyphoplasty. Following adjusted analysis, having a dependent functional health status pre-operatively (OR 1.78; p = 0.010), pre-operative sepsis/SIRS (OR 2.52; p = 0.009), history of COPD (OR 1.62; p = 0.025), disseminated cancer (OR 1.94; p = 0.028), pre-operative wound infection (OR 3.47; p = 0.003) and inpatient admission status (OR 3.22; p < 0.001) were independent predictors of having any complication within 30-days of the procedure. Significant independent risk factors for 30-day mortality were functional health status prior to surgery (OR 2.92; p = 0.002), pre-operative dialysis use (OR 11.74; p = 0.003), Disseminated cancer (OR 7.09; p < 0.001), chronic steroid use (OR 3.59; p < 0.001), and inpatient admission status (OR 4.95; p < 0.001). ConclusionVertebroplasty/Kyphoplasty is associated with significant adverse outcomes. Providers can utilize these data to better pre-operatively filter high-risk patients and tailor an appropriate peri-operative medical optimization program to enhance care to lower the risk of complications, readmissions and mortality from this procedure.
