Does intraoperative neurophysiologic monitoring matter in noncomplex spine surgeries?

ABSTRACT: To determine associations between intraoperative neurophysiologic monitoring (IOM) for spinal decompressions and simple fusions with neurologic complications, length of stay, and hospitalization charges.Adult discharges in the Nationwide/National Inpatient Sample (NIS) (2007-2012) with spinal decompressions and simple spinal fusions were included. Revision surgeries, instrumentations, complicated approaches, and tumor- and trauma-related surgeries were excluded. Extracted data included patient demographics, medical comorbidities, primary spinal surgery type, and hospital characteristics. Bivariate and multiple regression analyses using NIS survey design variables correlated IOM use with neurologic complications, hospital charges, and length of stay.IOM was reported in 4.9% of an estimated 1.1 million discharges in the weighted sample. Discharges reporting IOM were more often privately insured (61% vs 57%, p < 0.001) and had slightly more comorbidities (25% vs 24% with 3+ comorbidities, p = 0.01). Spinal fusions more often reported IOM than decompressions. The IOM group had fewer neurologic complications (0.8% vs 1.4% of controls) with no difference in length of stay (3.0 days for each group), but increased hospital charges (39% greater). Multiple regression adjustment showed significant associations of IOM with fewer neurologic complications (odds ratio 0.60, 95% confidence interval [CI] 0.47, 0.76, p < 0.001), while the estimated percentage of hospital charges was sizably diminished from the unadjusted analysis (IOM effect +9%, 95% CI +4%, +13%, p < 0.001), and length of stay was reduced (IOM effect -0.26 days, 95% CI -0.42, -0.11, p < 0.001).IOM was associated with better clinical outcomes and some increased hospital charges among discharges of simple spinal fusions and laminectomies in a large, multiyear, nationally representative dataset.

Project description:PurposeMany minimally invasive surgical (MIS) techniques have been developed for instrumentation of spine. These MIS techniques restore stability, alignment while achieving return to function quite early as compared to open spine surgeries. The main aim of this review was to evaluate role, indications and complications of these MIS techniques in Thoracolumbar and Lumbar fractures.MethodsPubmed search using key words such as"Percutaneous pedicle screw for Thoracolumbar fractures" and "Video Assisted Thoracoscopy, Thoracoscopic, VATS for thoracolumbar, Lumbar and Spine fractures" were used till July 2016 while doing literature search. Authors analyzed all the articles, which came after search; the articles relevant to the topic were selected and used for the study. Both prospective and retrospective case control studies and randomized control trials (RCT's) were included in this review. Case reports and reviews were excluded. Studies demonstrating use of MIS in cases other than spine trauma and studies with lack of clinical follow up were excluded from this review. Variables such as number of patients, operative time and complications were evaluated in each study.ResultsAfter pubmed search, we found total 68 studies till July 2016 out of which eight studies were relevant for analysis of Video Assisted Thoracoscopy for thoracolumbar and lumbar fractures. Total 72 articles for Percutaneous pedicle screws in thoracolumbar and lumbar fractures were retrieved out of which percutaneous pedicle screws were analyzed in eleven studies and twelve studies involved comparison of percutaneous pedicle screws and conventional open techniques.ConclusionRole and Indications of the MIS techniques in spinal trauma are expanding quite rapidly. MIS techniques restore stability, alignment while achieving early return to function and lower infection rates as compared to open spine surgeries. In long term, they provide good kyphosis correction and stable fixation and fusion of spine. They are associated with long learning curve and technical challenges but with careful patient selection and in expert hands, MIS techniques may produce better results than open trauma spine surgeries.

Project description:BackgroundIn this study we proposed a new strategy to measure cost-effectiveness of second opinion program on spine surgery, using as measure of effectiveness the minimal important change (MIC) in the quality of life reported by patients, including the satisfaction questionnaire regarding the treatment and direct medical costs.MethodsRetrospective analysis of patients with prior indication for spine surgery included in a second opinion program during May 2011 to May 2019. Treatment costs and outcomes were compared considering each patients' recommended treatment before and after the second opinion. Costs were measured under the perspective of the hospital, including hospital stay, surgical room, physician and staff fees and other costs related to hospitalization when surgery was performed and physiotherapy or injection costs when a conservative treatment was recommended. Reoperation costs were also included. For comparison analysis, we used data based on our clinical practice, using data from patients who underwent the same type of surgical procedure as recommended by the first referral. The measure of effectiveness was the percentage of patients who achieved the MIC in quality of life measured by the EQ-5D-3 L 2 years after starting treatment. An incremental cost-effectiveness ratio (ICER) was calculated.ResultsBased upon the assessment of 1,088 patients that completed the entire second opinion process, conservative management was recommended for 662 (60.8%) patients; 49 (4.5%) were recommended to injection and 377 (34.7%) to surgery. Complex spine surgery, as arthrodesis, was recommended by second opinion in only 3.7% of cases. The program resulted in financial savings of -$6,705 per patient associated with appropriate treatment indication, with an incremental effectiveness of 0.077 patients achieving MIC when compared to the first referral, resulting in an ICER of $-87,066 per additional patient achieving the MIC, ranging between $-273,016 and $-41,832.ConclusionAfter 2 years of treatment, the second opinion program demonstrated the potential for cost-offsets associated with improved quality of life.
