comparing decompression alone to decompression plus fusion procedures. Methods From the Quality Outcomes Database (QOD), formerly known as the National Neurosurgery Quality and Outcomes Database (N 2 QOD), 2 , 17 we collected de-identified data on all patients enrolled with a diagnosis of LSS who had complete preoperative, operative, and 1-year postoperative data. The QOD is a prospective observational registry that records 30-day morbidity and preoperative, 3-month postoperative, and 12-month postoperative quality and patient-reported outcomes (PROs) data

recognized need to quickly and effectively respond to intraoperative monitoring changes in a cohesive fashion, we sought to develop a checklist for responding to intraoperative monitoring alerts. Despite the recent momentum behind surgical checklists, checklists are not without their flaws and pitfalls, 2 , 3 , 9 , 25 , 42 , 47 , 52 nor are they simplistic or straightforward to implement. 7 , 47 Table 2 depicts the pros and cons associated with surgical checklist use.

proportions were compared using Fisher’s exact test. All statistical analyses were conducted using JMP Pro 11 (SAS Institute). The threshold for significance was p < 0.05. Results A total of 9852 patients were identified in the QOD lumbar registry database. The mean age of the cohort was 54.2 years (SD 16.7 years) with 5144 (52.2%) men and 4704 (47.8%) women. There were 3696 (37.5%) Medicare beneficiaries and 6156 (62.5%) with private medical insurance coverage ( Table 1 ). Overall, 200 patients (2.0%) returned to the operating room within 30 days and 616 patients (6

Wizard Pro 1.8.28 was used for preliminary statistical analysis and Review Manager v5.3 (Nordic Cochrane Centre, Rigshospitalet, 2008) was used for meta-analysis. Results A total of 96 studies were excluded (5 based on the title; 54 based on review of the abstract; and 39 based on full-text review), yielding 9 included studies ( Table 1 ): 1 of these studies described trans-spinal magnetic stimulation, 2 7 studies described DBS implantation targeting the subthalamic nucleus (STN), 3 , 11 , 35 , 36 , 39

T he enactment of the Patient Protection and Affordable Care Act in 2010 established the foundation for the national standardization of health care delivery, ultimately leading to wide-ranging legislative oversight and determination of health care value. 18 Given the rapid growth and associated cost of surgical procedures, there is increasing interest in producing objective data to determine the quality of care and inform the allocation of health care resources. Patient-reported outcomes (PROs) are gaining a central role in evaluating the effectiveness of

proposed a focused project to determine the impact of fusion on patient-reported outcomes (PROs). Preoperative radiographs, standing or dynamic, were evaluated by surgeons at the participating site to confirm the diagnosis of Grade I spondylolisthesis. All surgical variables, including laminectomy performed, fusion performed, and number of levels of fusion or laminectomy, MIS versus open surgery, were audited for all eligible patients. Patients who underwent elective lumbar spine surgery for Grade I spondylolisthesis (according to the Meyerding classification 17 (via a

(PROs) on smokers and nonsmokers. Methods Data Source Patients undergoing elective spine surgery for degenerative lumbar disease were entered into the prospective multicenter QOD registry over a 2-year period. The QOD is a prospective observational registry designed to collect measures of surgical safety and PROs at 12 months after surgery and establish risk-adjusted expected morbidity. The overall goal is to improve efficiency and quality of care for the most common lumbar surgical procedures performed by spine surgeons. The QOD registry enrolls spine surgery
