statistical analyses were conducted using Prism 6.0 (GraphPad) as well as JMP Pro 12.2 (SAS Institute Inc.). Web-Based Literature Search and Data Collection A systematic review in compliance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines 23 was performed to estimate the overall pooled diagnostic accuracy of IONM in ID-EM spinal tumor resection, utilizing the term “(intraoperative monitoring spinal tumor) OR (intraoperative monitoring spine tumor) OR (intraoperative monitoring spinal neoplasm)” in the PubMed, Embase, Web of

variables, IOM parameters, and 90-day surgical morbidity. Patient reported outcomes (PRO), return to work and medical resource utilization were prospectively recorded at baseline and 3-months. CPT codes 95920[baseline electrophysiologic testing (charged per hour)], 95295 and 95926[SSEP monitoring], 95928 and 95929[MEP monitoring], and 95937[neuromuscular junction testing] were used to calculate the direct cost of using IOM for cervical surgery(Payer perspective). The cost of IOM per reduction in surgical morbidity (Cost-benefit analysis), and the difference in mean total

. Therefore, we set out to determine the impact of complications on effectiveness, cost and value of spine surgery. Methods All patients undergoing elective lumbar surgery for degenerative spine disease were enrolled into a prospective registry. Data was collected on patient demographics, treatment variables and complications. Patient reported outcomes (PROs) and medical resource utilization were prospectively recorded at baseline and 1-year. Surgical DRG/CPT based medicare fees and medical resource utilization were used to estimate direct healthcare costs. Patient

treatments from pharmacologic to surgical, from manipulation to modality, will allow for better understanding and value driven decision-making. Patient reported outcome (PRO) measures are the current standard and include general and disease specific measures. The Oswestry Disability Index (ODI) is the most commonly used disease specific patient reported outcome tool to measure functional disability related to back pain. Few studies have evaluated its psychometric properties in a large patient sample using a modern tool such as the Rasch analysis model. This study aims to

We sought to characterize the accuracy of patient recall of preoperative symptoms in a cohort of lumbar spine surgery patients. Materials/Methods: We analyzed consecutive patients undergoing lumbar decompression or decompression and fusion for

Public insurance group comprised of significantly comorbid(p <0.001) and unemployed patients(p <0.001). There was no difference in baseline PROs between groups. Number of motion segments involved was higher in public insurance group(p <0.001). There was significant difference in the types of surgeries between the two groups(p <0.001). Length of surgery(p=0.004) and hospital stay(p=0.006) was significantly higher in public insurance group

Obtaining long-term PROs can be costly and challenging. To determine if 1-year PROs can accurately assess effective spine care for
