Background Context
Significant variability in neurologic outcomes after surgical correction for adult spinal deformity (ASD) has been reported. Risk factors for decline in neurologic motor outcomes are poorly understood.Purpose
The objective of the present investigation was to identify the risk factors for postoperative neurologic motor decline in patients undergoing complex ASD surgery.Study Design/Setting
This is a prospective international multicenter cohort study.Patient Sample
From September 2011 to October 2012, 272 patients undergoing complex ASD surgery were prospectively enrolled in a multicenter, international cohort study in 15 sites.Outcome Measures
Neurologic decline was defined as any postoperative deterioration in American Spinal Injury Association lower extremity motor score (LEMS) compared with preoperative status.Methods
To identify risk factors, 10 candidate variables were selected for univariable analysis from the dataset based on clinical relevance, and a multivariable logistic regression analysis was used with backward stepwise selection.Results
Complete datasets on 265 patients were available for analysis and 61 (23%) patients showed a decline in LEMS at discharge. Univariable analysis showed that the key factors associated with postoperative neurologic deterioration included older age, lumbar-level osteotomy, three-column osteotomy, and larger blood loss. Multivariable analysis revealed that older age (odds ratio [OR]=1.5 per 10 years, 95% confidence interval [CI] 1.1–2.1, p=.005), larger coronal deformity angular ratio [DAR] (OR=1.1 per 1 unit, 95% CI 1.0–1.2, p=.037), and lumbar osteotomy (OR=3.3, 95% CI 1.2–9.2, p=.022) were the three major predictors of neurologic decline.Conclusions
Twenty-three percent of patients undergoing complex ASD surgery experienced a postoperative neurologic decline. Age, coronal DAR, and lumbar osteotomy were identified as the key contributing factors. 相似文献2.

Background Context
There is a lack of information about postoperative outcomes and related risk factors associated with spinal surgery in patients with Parkinson's disease (PD).Purpose
This study aimed to investigate the postoperative morbidity and mortality associated with spinal surgery for patients with PD, and the risk factors for poor outcomes.Study Design
This is a retrospective matched-pair cohort study.Patient Sample
Data of patients who underwent elective spinal surgery between July 2010 and March 2013 were extracted from the Diagnosis Procedure Combination database, a nationwide inpatient database in Japan.Outcome Measures
In-hospital mortality and occurrence of postoperative complications.Methods
For each patient with PD, we randomly selected up to four age- and sex-matched controls in the same hospital in the same year. The differences in in-hospital mortality and occurrence of postoperative complications were compared between patients with PD and controls. A multivariable logistic regression model fitted with a generalized estimation equation was used to identify significant predictors of major complications (surgical site infection, sepsis, pulmonary embolism, respiratory complications, cardiac events, stroke, and renal failure). Multiple imputation was used for missing data.Results
Among 154,278 patients undergoing spinal surgery, 1,423 patients with PD and 5,498 matched controls were identified. Crude in-hospital mortality was higher in patients with PD than in controls (0.8% vs. 0.3%, respectively). The crude proportion of major complications was also higher in patients with PD (9.8% vs. 5.1% in controls). Postoperative delirium was more common in patients with PD (30.3%) than in controls (4.3%). Parkinson's disease was a significant predictor of major postoperative complications, even after adjusting for other risk factors (odds ratio, 1.74; 95% confidence intervals, 1.37–2.22; p<.001).Conclusions
Patients with PD had a significantly increased risk of postoperative complications following spinal surgery. Postoperative delirium was the most frequently observed complication. 相似文献3.

Background Context
Intraoperative monitoring (IOM) is an essential method for preventing postoperative spinal deficits during posterior vertebral column resection (VCR) surgery for treatment of severe spine deformities, but the IOM features directing at VCR procedures are rarely reported and need to be further clarified.Purpose
To evaluate an important surgical point that will lead to the IOM loss frequently, and then remind the surgeons to pay close attention to impending monitoring changes during posterior VCR surgery.Study Design/Setting
Retrospective study.Patient Sample
A total of 77 patients with severe spine deformities who underwent posterior VCR and deformity correction surgeries from January 2012 to May 2015 are retrospectively analyzed in our spine center.Outcome Measures
IOM (motor-evoked potentials [MEP] and somatosensory-evoked potentials) was used for intraoperative spinal function assessment.Methods
Patients were divided into 2 groups according to their preoperative spinal function, including 27 patients with preoperative spinal deficits and 50 patients with spinal normal. And the IOM data during surgery, especially among VCR procedures, were mainly analyzed in the present study.Results
With the VCR procedure almost complete, most patients showed varying degrees of IOM loss that included 37 cases showing obvious IOM degenerations and 21 cases showing significant IOM loss with alerts immediately. Moreover, the patients with preoperative spinal deficits have more significant decreasing percentage in MEP amplitude (81% vs. 68%, p<.05) than those patients without.Conclusions
With the VCR procedure almost complete, surgeons must pay closely attention to the IOM signals and should be ready to take corresponding surgical measures to deal with the impeding monitoring loss. 相似文献4.
Background Context
Cowden syndrome is an autosomal dominant syndrome characterized by multiple hamartomas and an increased cancer risk. It is associated with mutations in the phosphatase and tensin homologue (PTEN) gene that encodes a tumor suppressant phosphatase.Purpose
The study aimed to report an unusual case of multiple spinal epidural arteriovenous fistulas in a patient diagnosed with Cowden syndrome.Study Design
This is a case report.Patient Sample
The patient is a 57-year-old woman.Methods
We report the case of a 57-year-old woman with a history of multiple cancers, with acute exacerbation of lower extremity weakness and numbness that had progressed over a month.Results
Magnetic resonance imaging showed abnormal signal in the thoracolumbar spinal cord, with enhancement after contrast administration. A spinal angiogram confirmed the presence of multiple spinal epidural arteriovenous fistulas. Genetic testing confirmed the diagnosis of Cowden syndrome with a mutation in intron 3 of the PTEN gene.Conclusions
Spinal vascular malformations occur in patients with Cowden syndrome, and they can be multifocal and locally aggressive. It is important to raise the suspicion of Cowden syndrome in patients with spinal cord vascular anomalies and a history of multiple cancers, as the correct genetic diagnosis may have implications for management and cancer screening. 相似文献5.

Background Context
Numerous studies have analyzed the impact of rheumatoid arthritis (RA) on the cervical spine and its related surgical interventions. However, there is a paucity of literature available conducting the same analyses in patients with non-cervical spine involvement.Purpose
The objective of this study was to compare patient characteristics, comorbidities, and complications in patients with and without RA undergoing primary non-cervical spinal fusions.Study Design/Setting
This is a retrospective national database review.Patient Sample
A total of 52,818 patients with adult spinal deformity undergoing non-cervical spinal fusions (1,814 patients with RA and 51,004 patients without RA).Outcome Measures
The outcome measures in the study include patient characteristics, as well as complication and mortality rates.Materials and Methods
Using the Nationwide Inpatient Sample from 2003 to 2014, International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnosis and procedure codes were used to identify patients aged ≥18 years old with and without RA undergoing primary non-cervical spinal fusions. Univariate analysis was used to determine patient characteristics, comorbidities, and complication values for each group. Bivariate analysis was used to compare the two groups. Significance was set at p<.05.Results
Patients with RA were older (p<.001), were more likely to be women (p<.001), had increased rates of osteoporosis (p<.001), had a greater percentage of their surgeries reimbursed by Medicare (p<.001), and more often had weekend admissions (p=.014). There was no difference in all the other characteristics. Patients with RA had higher rates of iron deficiency anemia, congestive heart failure, chronic pulmonary disease, depression, and fluid and electrolyte disorders (all, p<.001). Patients without RA had higher rates of alcohol abuse (p=.027). There was no difference in all the other complications. There was no difference in mortality rate (p=.99). Total complications were greater in patients with RA (p<.001). Patients with RA had higher rates of infection (p=.032), implant-related complications (p=.010), incidental durotomies (p=.001), and urinary tract infections (p<.001). No difference existed among the other complications.Conclusions
Patients with RA have an increased number of comorbidities and complication rates compared with patients without RA. Such knowledge can help surgeons and patients with RA have beneficial preoperative discussions regarding outcomes. 相似文献6.

Background Context
Even though catastrophizing can negatively moderate the outcome of surgery for lumbar spinal stenosis (LSS), it is still unclear whether pain catastrophizing is an enduring stable or a dynamic structure related to pain intensity after spine surgery.Purpose
The purpose of this study was to determine whether catastrophizing would change in patients who undergo spinal surgery for LSS.Study Design
A prospective observational cohort study was carried out.Study Sample
Patients who underwent spine surgery for LSS comprised the study sample.Outcome Measures
The Visual Analog Pain Scale (VAS) scores for back/leg pain, Oswestry Disability Index (ODI), and Pain Catastrophizing Scale (PCS) were the outcome measures.Methods
The present observational cohort consisted of 138 patients between the ages of 40 and 80 years who were scheduled to undergo surgery for LSS. Among them, a total of 96 patients underwent a 3-year assessment after surgery. The PCS questionnaire was used for pain catastrophizing assessment before and 3 years after surgery. The VAS for back and leg pain, and ODI were assessed 3 and 6 months, and 1 and 3 years after surgery. The correlations between variables were analyzed before and 3 years after surgery. To clarify the causal relationship, time-series and linear mixed models were also used.Results
At 3 years after surgery, ODI, VAS for back and leg pain, and PCS scores were significantly decreased. The correlation of PCS with VAS and ODI was significant both before and 3 years after surgery. The correlation between change in pain or disability and change in pain catastrophizing from preoperative to 3 years after surgery was also significant. In the causal relationship between pain and catastrophizing, overall changes in pain and disability were significant predictors of overall changes in pain catastrophizing from baseline to 3 year after surgery.Conclusion
The present study shows that pain catastrophizing can change in association with the improvement in pain intensity after spine surgery. Therefore, catastrophizing may not be an enduring stable construct, but a dynamic construct. 相似文献7.

Background Context
Predicting survival outcomes after radiation therapy (RT) alone for metastatic disease of the spine is a challenging task that is important to guiding treatment decisions (eg, determining dose fractionation and intensity). The New England Spinal Metastasis Score (NESMS) was recently introduced and validated in independent cohorts as a tool to predict 1-year survival following surgery for spinal metastases. This metric is composed of three factors: preoperative albumin, ambulatory status, and modified Bauer score, with the total score ranging from 0 to 3.Purpose
The purpose of this study was to assess the applicability of the NESMS model to predict 1-year survival among patients treated with RT alone for spinal metastases.Study Design/Setting
This study is a retrospective analysis.Patient Sample
This sample included 290 patients who underwent conventional RT alone for spinal metastases.Outcome Measures
Patients' NESMS (composed of ambulatory status, pretreatment serum albumin, and modified Bauer score) were assessed, as well as their 1-year overall survival rates following radiation for metastatic disease of the spine.Materials and Methods
This study is a single-institution retrospective analysis of 290 patients treated with conventional radiation alone for spinal metastases from 2008 to 2013. The predictive value of the NESMS was assessed using multivariable logistic regression modeling, adjusted for potential confounding variables.Results
This analysis indicated that patients with lower NESMSs had higher rates of 1-year mortality. Multivariable analysis demonstrated a strong association between lower NESMSs and lower rates of survival.Conclusions
The NESMS is a simple prognostic scheme that requires clinical data that are often readily available and have been validated in independent cohorts of surgical patients. This study serves to validate the utility of the NESMS composite score to predict 1-year mortality in patients treated with radiation alone for spinal metastases. 相似文献8.

Background Context
Short-segment posterior spinal instrumentation for thoracolumbar burst fracture provides superior correction of kyphosis by an indirect reduction technique, but it has a high failure rate.Purpose
The purpose of the study we report here was to compare outcomes for temporary short-segment pedicle screw fixation with vertebroplasty and for such fixation without vertebroplasty.Study Design
This is a prospective multicenter comparative study.Patient Sample
We studied 62 consecutive patients with thoracolumbar burst fracture who underwent short-segment posterior instrumentation using ligamentotaxis with Schanz screws with or without vertebroplasty.Outcome Measures
Radiological parameters (Cobb angle on standing lateral radiographs) were used.Methods
Implants were removed approximately 1 year after surgery. Neurologic function, kyphotic deformity, canal compromise, and fracture severity were evaluated prospectively.Results
After surgery, all patients with neurologic deficit had improvement equivalent to at least one grade on the American Spinal Injury Association impairment scale and had fracture union. Kyphotic deformity was reduced significantly, and reduction of the vertebrae was maintained with and without vertebroplasty, regardless of load-sharing classification. Although no patient required additional anterior reconstruction, kyphotic change was observed at disc level mainly after implant removal with or without vertebroplasty.Conclusions
Temporary short-segment fixation yielded satisfactory results in the reduction and maintenance of fractured vertebrae with or without vertebroplasty. Kyphosis recurrence may be inevitable because adjacent discs can be injured during the original trauma. 相似文献9.

Background Context
The current standard of care for prediction of survival of cancer staging is based on TNM staging. However, for patients with spinal metastasis, who all have identical stage IV disease, identifying accurate prognostic markers of survival would allow better treatment stratification between more aggressive treatment strategies or palliation. Analytical morphometrics enables physicians to quantify patient frailty by measuring lean muscle mass. Morphometrics also predicts survival in patients with lung cancer metastases to the spine.Purpose
Our study evaluates whether morphometrics is predictive of survival in patients with breast cancer spinal metastasis.Design
This is an observational retrospective cohort study.Patient Sample
This study includes female patients with breast cancer spinal metastases and patients who have undergone stereotactic body radiation therapy.Outcome Measures
Overall survival was the primary outcome measure.Methods
Morphometric measurements of the psoas muscle were taken using computed tomography scans of the lumbar spine. We then stratified patients into tertiles based on the psoas muscle area.Results
We identified 118 patients, with a median survival of 104 days (95% confidence interval [CI]=73–157 days). Overall survival was not associated with age, chemotherapy, or number of levels radiated. Patients in the lowest tertile of psoas size had significantly shorter survival compared with the highest tertile (68 days versus 148 days, hazard ratio 1.76 [95% CI=1.08–2.89], p=.024). The shorter survival was also true for the lowest tertile versus the middle tertile (68 days versus 167 days, hazard ratio 1.95 [95% CI=1.19–3.19], p=.007). Kaplan-Meier survival curves were used to visually illustrate the differences in survival between different tertiles.Conclusions
Morphometric analysis of the psoas muscle size in patients with breast cancer metastases to the spine was effective in identifying patients at risk of shorter survival. Further research is needed to validate these results, as well as to see if these methodologies can be applied to other cancer histologies. 相似文献11.

Background Context
Most of the papers correlate sagittal radiographic parameters with health-related quality of life (HRQOL) scores for patients with scoliosis. However, we do not know how changes in sagittal profile influence clinical outcomes after surgery in adult population operated for mainly frontal deformity.Purpose
This study aimed to analyze spinal sagittal profile in a population operated on adult idiopathic scoliosis (AS) and to describe variations in sagittal parameters after surgery and the association between those variations and clinical outcomes.Design/Setting
This is a historical cohort study.Patient Sample
We included in this study 40 patients operated on AS, older than 40 at the time of surgery (mean age 54.9), and with more than 2-year follow-up (mean 7.4 years).Outcome Measures
Full-length free-standing radiographs, Scoliosis Research Society 22 (SRS22) and Short Form 36 (SF36) instruments, and satisfaction with outcomes were available at final follow-up.Methods
Sagittal preoperative and final follow-up radiographic parameters, radiographic correlation with HRQOL scores at final follow-up, and association between satisfaction and changes in sagittal profile were analyzed. A multivariate analysis was performed. No funds were received for this article.Results
Preoperatively, the spinal sagittal plane tended to exhibit kyphosis. Most sagittal parameters did not improve at final follow-up with respect to preoperative values. We saw, after univariate analysis, that worse sagittal profile leads to worse HRQOL, but after multivariate analysis, only spinal tilt (ST) persisted as possible predictor for worse SRS activity scores. Frontal Cobb significantly improved. Most patients (82%) were satisfied with final outcomes. Variations in sagittal profile parameters did not differ between satisfied and dissatisfied patients.Conclusions
Although most sagittal plane parameters did not improve after surgery, surgical treatment in AS achieves a high satisfaction rate. Good clinical results do not correlate with improving sagittal plane parameters. Sagittal profile measurements are not helpful to decide surgical treatment in patients with mainly frontal deformity. 相似文献12.

Background Context
Lidocaine has emerged as a useful adjuvant anesthetic agent for cases requiring intraoperative monitoring of motor-evoked potentials (MEPs) and somatosensory-evoked potentials (SSEPs). A previous retrospective study suggested that lidocaine could be used as a component of propofol-based intravenous anesthesia without adversely affecting MEP or SSEP monitoring, but did not address the effect of the addition of lidocaine on the MEP and SSEP signals of individual patients.Purpose
The purpose of this study was to examine the intrapatient effects of the addition of lidocaine to balanced anesthesia on MEPs and SSEPs during multilevel posterior spinal fusion.Study Design
This is a prospective, two-treatment, two-period crossover randomized controlled trial with a blinded primary outcome assessment.Patient Sample
Forty patients undergoing multilevel posterior spinal fusion were studied.Outcome Measures
The primary outcome measures were MEP voltage thresholds and SSEP amplitudes. Secondary outcome measures included isoflurane concentrations and hemodynamic parameters.Methods
Each participant received two anesthetic treatments (propofol 50?mcg/kg/h and propofol 25?mcg/kg/h+lidocaine 1?mg/kg/h) along with isoflurane, ketamine, and diazepam. In this manner, each patient served as his or her own control. The order of administration of the two treatments was determined randomly.Results
There were no significant within-patient differences between MEP threshold voltages or SSEP amplitudes during the two anesthetic treatments.Conclusions
Lidocaine may be used as a component of balanced anesthesia during multilevel spinal fusions without adversely affecting the monitoring of SSEPs or MEPs in individual patients. 相似文献13.

Background context
Previous studies found that the intervertebral disc (IVD) experiences the greatest loads during spinal manipulation therapy (SMT).Purpose
Based on that, this study aimed to determine if loads experienced by spinal tissues are significantly altered when the application site of SMT is changed.Study Design
A biomechanical robotic serial dissection study.Sample
Thirteen porcine cadaveric motion segments.Outcome Measures
Forces experienced by lumbar spinal tissues.Methods
A servo-controlled linear actuator provided standardized 300 N SMT simulations to six different cutaneous locations of the porcine lumbar spine: L2–L3 and L3–L4 facet joints (FJ), L3 and L4 transverse processes (TVP), and the space between the FJs and the TVPs (BTW). Vertebral kinematics were tracked optically using indwelling bone pins; the motion segment was removed and mounted in a parallel robot equipped with a six-axis load cell. Movements of each SMT application at each site were replayed by the robot with the intact specimen and following the sequential removal of spinal ligaments, FJs and IVD. Forces induced by SMT were recorded, and specific axes were analyzed using linear mixed models.Results
Analyses yielded a significant difference (p<.05) in spinal structures loads as a function of the application site. Spinal manipulative therapy application at the L3 vertebra caused vertebral movements and forces between L3 and L4 spinal segment in the opposite direction to when SMT was applied at L4 vertebra. Additionally, SMT applications over the soft tissue between adjacent vertebrae significantly decreased spinal structure loads.Conclusion
Applying SMT with a constant force at different spinal levels creates different relative kinetics of the spinal segments and load spinal tissues in significantly different magnitudes. 相似文献14.
Background Context
Studies have shown that pain acceptance strategies related to psychological flexibility are important in the presence of chronic musculoskeletal pain. However, the predictors of these strategies have not been studied extensively in patients with whiplash-associated disorders (WAD).Purpose
The purpose of this study was to predict chronic pain acceptance and engagement in activities at 1-year follow-up with pain intensity, fear of movement, perceived responses from significant others, outcome expectancies, and demographic variables in patients with WAD before and after multimodal rehabilitation (MMR).Study design
The design of this investigation was a cohort study with 1-year postrehabilitation follow-up.Study setting
The subjects participated in MMR at a Swedish rehabilitation clinic during 2009–2015.Patient sample
The patients had experienced a whiplash trauma (WAD grade I–II) and were suffering from pain and reduced functionality. A total of 386 participants were included: 297 fulfilled the postrehabilitation measures, and 177 were followed up at 1 year after MMR.Outcome measures
Demographic variables, pain intensity, fear of movement, perceived responses from significant others, and outcome expectations were measured at the start and after MMR. Chronic pain acceptance and engagement in activities were measured at follow-up.Methods
The data were obtained from a Swedish Quality Registry for Pain Rehabilitation (SQRPR).Results
Outcome expectancies of recovery, supporting and distracting responses of significant others, and fear of (re)injury and movement before MMR were significant predictors of engagement in activities at follow-up. Pain intensity and fear of (re)injury and movement after MMR significantly predicted engagement in activities at follow-up. Supporting responses of significant others and fear of (re)injury and movement before MMR were significant predictors of pain acceptance at the 1-year follow-up. Solicitous responses of significant others and fear of (re)injury and movement at postrehabilitation significantly predicted pain acceptance at follow-up.Conclusion
For engagement in activities and pain acceptance, the fear of movement appears to emerge as the strongest predictor, but patients' perceived reactions from their spouses need to be considered in planning the management of WAD. 相似文献15.

Background Context
Preoperative depression is increasingly understood as an important predictor of patient outcomes after spinal surgery. In this study, we examine the relationship between depression and patient-reported functional outcomes (PRFOs), including disability and pain, at various time points postoperatively.Purpose
The objective of this study was to analyze the use of depression, as measured by the 9-Item Patient Health Questionnaire (PHQ-9), as a means of assessing postoperative patient-reported disability and pain.Study Design/Setting
This study includes an analysis of prospective non-randomized spine registry compiled through an academic multispecialty group practice model.Patient Sample
A total of 1,000 spinal surgery patients from an affiliated surgical registry, enrolled from January 2010 onward, were included in this study.Outcome Measures
Pain was assessed via the visual analog scale (VAS) for leg or back pain. Disability was measured by the Oswestry Disability Index (ODI). Depression was measured by the PHQ-9.Methods
Patient data were collected preoperatively and at 1, 4, 10, and 24 months postoperatively. Data were analyzed via analysis of variance and Pearson correlation coefficient.Results
All patient stratifications analyzed experienced improvements in pain and ability postoperatively, as measured by the VAS and the ODI, respectively. Moderately and severely depressed patients (as measured by preoperative PHQ-9) experienced decreases in the mean PHQ-9 score of ?6.00 and ?7.96 24 months after surgery, respectively.Conclusions
In all groups, spinal surgery was followed by relief of pain and improved PRFO. Preoperative depression, as measured by the PHQ-9, predicted postoperative PRFO. Patients with moderate to severe depression as measured by the PHQ-9 experienced large mean decreases in the PHQ-9 score postoperatively. As a psychosocial metric, the PHQ-9 is a useful method of assessing value-added service of a spinal surgery. 相似文献16.

Background Context
Traumatic spinal injuries are often associated with both long-term disability, higher frequency of hospital readmissions, and high medical costs for individuals of all ages. Age differences in terms of injury profile and health outcomes among those who sustain a spinal cord injury have been identified. However, factors that may influence health outcomes among those with a spinal injury have not been extensively examined at a population level.Purpose
The present study aims to describe the characteristics of traumatic spinal injury, identify factors predictive of mortality, and estimate the cost of hospital treatment for younger and older people.Study Design/Setting
This is a population-based retrospective epidemiological study using linked hospitalization and mortality records during January 1, 2010 to June 30, 2014 in New South Wales, Australia.Patient Sample
The present study included 13,429 hospitalizations.Outcome Measures
Mortality within 30 and 90 days of hospitalization, hospital length of stay (LOS), and hospitalization costs were determined.Methods
Hospitalizations with a principal diagnosis of spinal cord injury or spinal fractures were used to identify traumatic spinal injuries. Age-standardized incidence rates were calculated and negative binomial regression was used to examine statistical significant changes over time. Cox proportional hazard regression was used to examine the effect of risk factors on survival at 90 days.Results
There were 13,429 hospitalizations, with 52.4% of individuals aged ≥65 years. The hospitalization rates for individuals aged ≤64 and ≥65 years were both estimated to significantly increase per year by 3.3% (95% confidence interval [CI] 0.97–5.79, p<.006) and 3.3% (95% CI 1.02–5.71, p=.005), respectively. For individuals aged ≥65 years, there were a higher proportion of women injured, comorbid conditions, injuries after a fall in the home or aged care facility, a longer hospital LOS, unplanned hospital admissions, and deaths than individual aged ≤64 years. The average cost per index hospitalization was AUD$23,808 for individuals aged ≤64 years and AUD$31,187 for individuals aged ≥65 years with a total estimated cost of AUD$371 million. Mortality risk at 90 days was increased for individuals who had one or more comorbidities, a higher injury severity score, and if their injury occurred in the home or an aged care facility.Conclusions
Spinal injury represents a substantial cost and results in debilitating injuries, particularly for older individuals. Spinal injury prevention efforts for older people should focus on the implementation of fall injury prevention, whereas for younger individuals, prevention measures should target road safety. 相似文献17.

Background Context
The incidence of incidental durotomy (ID) during total en bloc spondylectomy (TES) tends to be higher than that during other spinal surgeries because of the peculiarities of TES, including its highly invasive nature, epidural tumor extension, and use in patients who often have complicated medical backgrounds. However, there have been no detailed reports on ID associated with TES.Purpose
The study aimed to investigate ID during TES in detail.Study Design
This is a retrospective review of prospectively collected data.Patient Sample
The study included 105 consecutive patients with spinal tumor who underwent TES between May 2010 and February 2015 (59 men, 46 women; mean age, 54.0 years [range, 14–75 years] at the time of surgery).Outcome Measures
Outcome measures included the incidence, risk factors, anatomical location, intraoperative maneuvers, and postoperative course of ID associated with TES.Materials and Methods
Medical and operative records and imaging findings were reviewed. Univariate analysis and multivariable stepwise logistic regression models were used to identify independent risk factors for ID.Results
Incidental durotomy occurred in 18 (17.1%) of the 105 patients. The univariate and multivariate analyses demonstrated that older age (adjusted odds ratio [aOR], 6.09; 95% confidence interval [CI], 1.17–31.76; p=.03), radiotherapy (RT) history (aOR, 5.31; 95% CI, 1.46–19.49; p=.01), and revision surgery (aOR, 19.42; 95% CI, 3.46–109.14; p<.01) were independent risk factors for ID. Incidental durotomy was more likely to occur during dissection of tumor tissues in proximity to the nerve root. Although all of the ID cases were primarily sutured and covered with polyglycolic acid mesh and fibrin glue spray, eight cases required additional intervention because of intractable postoperative cerebrospinal fluid leakage. Six of these eight had a history of RT.Conclusions
Our results may help better identify high-risk patients for ID during TES, which may aid surgeons with optimal surgical decision making and in counseling patients on perioperative complications. 相似文献18.

Background Context
The Centers for Medicare and Medicaid Services (CMS) defines “adverse quality events” as the incidence of certain complications such as postsurgical hematoma or iatrogenic pneumothorax during an inpatient stay. Patient safety indicators (PSI) are a means to measure the incidence of these adverse events. When adverse events occur, reimbursement to the hospital decreases. The incidence of adverse quality events among patients hospitalized for primary spinal neoplasms is unknown. Similarly, it is unclear what the impact of insurance status is on adverse care quality among this patient population.Purpose
We aimed to determine the incidence of PSI among patients admitted with primary spinal neoplasms, and to determine the association between insurance status and the incidence of PSI in this population.Study Design
This is a retrospective cohort study.Patient Sample
We included all patients, 18 years and older, in the Nationwide Inpatient Sample (NIS) who were hospitalized for primary spine neoplasms from 1998 to 2011.Outcome Measures
Incidence of PSI from 1998 to 2011 served as outcome variable.Methods
The NIS was queried for all hospitalizations with a diagnosis of primary spinal neoplasm during the inpatient episode from 1998 to 2011. Incidence of PSI was determined using publicly available lists of International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnosis codes. Logistic regression models were used to determine the effect of primary payer status on PSI incidence. All comparisons were made between privately insured patients and Medicaid or self-pay patients.Results
We identified 6,095 hospitalizations in which a primary spinal neoplasm was recorded during the inpatient episode. We excluded patients younger than 18 years and those with “other” or “missing” primary insurance status, leaving 5,880 patients for analysis. After adjusting for patient demographics and hospital characteristics, Medicaid or self-pay patients had significantly greater odds of experiencing one or more PSI (odds ratio [OR] 1.81 95% confidence interval [CI] 1.11–2.95) relative to privately insured patients.Conclusions
Among patients hospitalized for primary spinal neoplasms, primary payer status predicts the incidence of PSI, an indicator of adverse health-care quality used to determine hospital reimbursement by the CMS. As reimbursement continues to be intertwined with reportable quality metrics, identifying vulnerable populations is critical to improving patient care. 相似文献19.

Background Context
Lumbar spinal stenosis is a common condition in the elderly for which costs vary substantially by region. Comparing differences between surgeons from a single institution, thereby omitting regional variation, could aid in identifying factors associated with higher costs and individual drivers of costs. The use of decision aids (DAs) has been suggested as one of the possible tools for diminishing costs and cost variation.Purpose
(1) To determine factors associated with higher costs for treatment of spinal stenosis in the first year after diagnosis in a single institution; (2) to find individual drivers of costs for providers with higher costs; and (3) to determine if the use of DAs can decrease costs and cost variability.Study Design
Retrospective cohort study.Patient Sample
A total of 10,858 patients in 18 different practices diagnosed with lumbar spinal stenosis between January 2003 and July 2015 in three associated hospitals of a single institution.Outcome Measures
Mean cost for a patient per provider in US dollars within 1 year after diagnosis of lumbar spinal stenosis.Methods
We collected all diagnostic testing, office visits, injections, surgery, and occupational or physical therapy related to lumbar spinal stenosis within 1 year after initial diagnosis. We used multivariable linear regression to determine independent predictors for costs. Providers were grouped in tiers based on mean total costs per patient to find drivers of costs. To assess the DAs effect on costs and cost variability, we matched DA patients one-to-one with non-DA patients.Results
Male gender (β 0.10, 95% confidence interval [CI] 0.05–0.15, p<.001), seeing an additional provider (β 0.77, 95% CI 0.69–0.86, p<.001), and having an additional spine diagnosis (β 0.79, 95% CI 0.74–0.84, p<.001) were associated with higher costs. Providers in the high cost tier had more office visits (p<.001), more imaging procedures (p<.001), less occupational or physical therapy (p=.002), and less surgery (p=.001) compared with the middle tier. Eighty-two patients (0.76%) received a DA as part of their care; there was no statistically significant difference between the DA group and the matched group in costs (p=.975).Conclusions
Male gender, seeing an additional provider, and having an additional spine diagnosis were independently associated with higher costs. The main targets for cost reduction we found are imaging procedures and number of office visits. Decision aids were not found to affect cost. 相似文献20.
