摘要: OBJECT Because of the limited data available regarding associations between risk factors and effect hospital case volume on outcomes after resection intradural spine tumors, authors attempted to identify these by using a large population-based database. METHODS Using National Inpatient Sample database, performed retrospective cohort study that involved patients who underwent surgery for an spinal tumor 2002 2011. national estimates, they identified patient demographics, medical comorbidities, characteristics with inpatient postoperative outcomes. In addition, unfavorable was investigated. Hospitals fewer than 14 resections in adult 2011 were labeled as low-volume centers, whereas those or more operations period classified high-volume centers (HVCs). These...
