Abstract

Objective: Previously, information on cervical corpectomy complication rates has been obtained from retrospective analysis of single-institution data. The aim of this study was to report 30-day mortality and complication rates after cervical corpectomy using multicenter prospective data from the Veterans Affairs National Surgical Quality Improvement Program database., Methods: The National Surgical Quality Improvement Program database was used to identify 1560 patients who underwent cervical corpectomy in United States Veterans Affairs hospitals from 1997 to 2006. Multivariate analysis was performed to analyze the effects of patient and hospital characteristics on morbidity and mortality rates., Results: A total of 1560 patients underwent corpectomy, with an overall in-hospital mortality rate of 1.6%, a complication rate of 18.4%, and a mean length of stay of 6 days. Multivariate analysis identified age older than 80 years (odds ratio [OR], 21.24), history of Type 1 diabetes (OR, 2.36), American Society of Anesthesiologists class greater than 3 (OR, 6.93), and dependent functional status (OR, 3.17) as the most significant preoperative predictors of complications. Three or more corpectomy levels (OR, 2.46) and operative duration longer than 6 hours (OR, 3.45) were also found to be significant predictors of postoperative complications. Patients who underwent 3 or more levels of corpectomy had a return-to-operating room rate of 17.9% and a graft/instrumentation failure rate of 5.4% compared with those who underwent single-level corpectomy, who had rates of 6.2 and 1.87%, respectively. Patients who were returned to the operating room had significantly higher mortality rates (7.0 versus 1.2%) and accounted for 39.9% of the total number of complications. Multivariate analysis identified age, American Society of Anesthesiologists class, history of disseminated cancer, and diabetes as the most significant predictors of mortality. Patients with Type 1 diabetes had 4-fold higher mortality rates compared with patients with no history of diabetes or diet-controlled diabetes., Conclusion: We have analyzed the morbidity and mortality data on the largest series of corpectomy reported to date. We have demonstrated the impact of age, American Society of Anesthesiologists class, and number of operated levels on complication rates. Type 1 diabetes was established as a strong risk factor for 30-day mortality after cervical corpectomy.

Abstract

Objective: There is little information about in-hospital complication rates, adverse outcomes, and mortality after spinal fusion for cervical spondylotic myelopathy (CSM). The aim of this study was to report inpatient mortality, complications, and outcomes on a national level., Methods: We used the National Inpatient Sample to identify 58,115 admissions of patients with CSM who underwent spinal fusion in the United States from 1993 to 2002. Multivariate analysis was performed to analyze the effects of patient and hospital characteristics on outcomes such as mortality, complications, discharge disposition, and length of stay., Results: A total of 58,115 patients with CSM underwent spinal fusion with an average mortality rate of 0.6%, a complication rate of 13.4%, and a mean length of stay of 4 days. Pulmonary (3.6%) and postoperative hemorrhages or hematomas (2.3%) were the most common complications reported. One postoperative complication led to a 4-day increase in mean length of stay, increased the mortality rate 20-fold, and added more than $10,000 to hospital charges. Multivariate analysis identified age, comorbidity, and admission type as the main predictors of mortality, complication rate, and adverse outcome. Patients aged > or =85 or 65 to 84 years had respective 44- and 14-fold increases in mortality, compared with patients in the 18- to 44-year age group. Patients older than 84 years had a 40-fold increase in adverse outcomes and a 5-fold likelihood of medical complications. Patients with three or more comorbidities had an increased risk of medical complications (odds ratio [OR], 1.98), adverse discharge (OR, 2.17), and in-hospital mortality (OR, 2.36). Elective admissions were associated with much lower rates of mortality (OR, 0.28), complication (OR, 0.68), and adverse outcome (OR, 0.26). Complications were greater for posterior fusion (16.4%) versus anterior fusion (11.9%) procedures. Anterior fusions were associated with a greater incidence of dysphagia (3%) and hoarseness (0.21%). Cervical spondylosis patients who presented without myelopathy had a much lower incidence of complications (6.3%)., Conclusions: We provide a national estimate of inpatient complications and outcomes after spinal fusion for CSM patients in the United States. We demonstrate the impacts of age, complications, and medical comorbidities on the outcome of surgery for patients with this common disorder. We provide complication rates stratified by age and medical comorbidities for elderly patients who present with CSM who need spinal fusion.
