Retrospective cohort study. To identify risk factors for poor short-term outcomes after vertebral augmentation procedures. Vertebral compression fractures are the most common fractures of osteoporosis and are frequently treated with vertebroplasty or kyphoplasty. There is a shortage of information about risk factors for short-term, general health outcomes after vertebral augmentation in the literature. Patients older than 65 years who underwent vertebroplasty or kyphoplasty in 2011 and 2012 were identified from the American College of Surgeons National Surgical Quality Improvement Program database. Patient characteristics were tested for association with 30-day adverse events, mortality, and readmission using bivariate and multivariate analyses. A total of 850 patients met inclusion criteria. The average age was 78.9±11.7 years (mean±standard deviation) and females made up 70.8% of the cohort. Of these patients, 9.5% had any adverse event (AAE), and 6.6% had a serious adverse event (SAE). Death occurred in 1.5% of patients, and 10.8% were readmitted within the first 30 postoperative days.On multivariate analysis, AAE and SAE were both significantly associated with American Society of Anesthesiologists class 4 (AAE: odds ratio [OR]=2.7, P=0.013; SAE: OR=2.5, P=0.040) and inpatient status before procedure (AAE: OR=2.7, P
