RESUMO
BACKGROUND: Spinal injuries are an urgent public health priority; nevertheless, no China-wide studies of these injuries exist. This study measured the incidence, prevalence, causes, regional distribution, and annual trends of spinal injuries in China from 1990 to 2019. METHODS: We used data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2019 to estimate the incidence and prevalence of spinal injuries in China. The data of 33 provincial-level administrative regions (excluding Taiwan, China) provided by the National Center for Chronic and Noncommunicable Disease Control and Prevention, Chinese Center for Disease Control and Prevention (CDC) were use to systematically analyze the provincial etiology, geographical distribution, and annual trends of spinal injuries. The Bayesian meta-regression tool DisMod-MR 2.1 was used to ensure the consistency among incidence, prevalence, and mortality rates in each case. RESULTS: From 1990 to 2019, the number of living patients with spinal injuries in China increased by 138.32%, from 2.14 million to 5.10 million, while the corresponding age-standardized prevalence increased from 0.20% (95% uncertainty interval [UI]: 0.18-0.21%) to 0.27% (95% UI: 0.26-0.29%). The incidence of spinal injuries in China increased by 89.91% (95% UI: 72.39-107.66%), and the prevalence increased by 98.20% (95% UI: 89.56-106.82%), both the most significant increases among the G20 countries; 71.00% of the increase could be explained by age-specific prevalence. In 2019, the incidence was 16.47 (95% UI: 12.08-22.00, per 100,000 population), and the prevalence was 358.30 (95% UI: 333.96-386.62, per 100,000 population). Based on the data of 33 provincial-level administrative regions provided by CDC, age-standardized incidence and prevalence were both highest in developed provinces in Eastern China. The primary causes were falls and road injuries; however, the prevalence and specific causes differed across provinces. CONCLUSIONS: In China, the overall disease burden of spinal injuries increased significantly during the past three decades but varied considerably according to geographical location. The primary causes were falls and road injuries; however, the prevalence and specific causes differed across provinces.

OBJECTIVE: The burden of spinal trauma in low- and middle-income countries (LMICs) is immense, and its management is made complex in such resource-restricted settings. Algorithmic evidence-based management is cost-prohibitive, especially with respect to spinal implants, while perioperative care is work-intensive, making overall care dependent on multiple constraints. The objective of this study was to identify determinants of decision-making for surgical intervention, improvement in function, and in-hospital mortality among patients experiencing acute spinal trauma in resource-constrained settings. METHODS: This study was a retrospective analysis of prospectively collected data in a cohort of patients with spinal trauma admitted to a tertiary referral hospital center in Dar es Salam, Tanzania. Data on demographic, clinical, and treatment characteristics were collected as part of a quality improvement neurotrauma registry. Outcome measures were surgical intervention, American Spinal Injury Association (ASIA) Impairment Scale (AIS) grade improvement, and in-hospital mortality, based on existing treatment protocols. Univariate analyses of demographic and clinical characteristics were performed for each outcome of interest. Using the variables associated with each outcome, a machine learning algorithm-based regression nonparametric decision tree model utilizing a bootstrapping method was created and the accuracy of the three models was estimated. RESULTS: Two hundred eighty-four consecutively admitted patients with acute spinal trauma were included over a period of 33 months. The median age was 34 (IQR 26-43) years, 83.8% were male, and 50.7% had experienced injury in a motor vehicle accident. The median time to hospital admission after injury was 2 (IQR 1-6) days; surgery was performed after a further median delay of 22 (IQR 13-39) days. Cervical spine injury comprised 38.4% of the injuries. Admission AIS grades were A in 48.9%, B in 16.2%, C in 8.5%, D in 9.5%, and E in 16.6%. Nearly half (45.1%) of the patients underwent surgery, 12% had at least one functional improvement in AIS grade, and 11.6% died in the hospital. Determinants of surgical intervention were age ≤ 30 years, spinal injury level, admission AIS grade, delay in arrival to the referral hospital, undergoing MRI, and type of insurance; admission AIS grade, delay to arrival to the hospital, and injury level for functional improvement; and delay to arrival, injury level, delay to surgery, and admission AIS grade for in-hospital mortality. The best accuracies for the decision tree models were 0.62, 0.34, and 0.93 for surgery, AIS grade improvement, and in-hospital mortality, respectively. CONCLUSIONS: Operative intervention and functional improvement after acute spinal trauma in this tertiary referral hospital in an LMIC environment were low and inconsistent, which suggests that nonclinical factors exist within complex resource-driven decision-making frameworks. These nonclinical factors are highlighted by the authors' results showing clinical outcomes and in-hospital mortality were determined by natural history, as evidenced by the highest accuracy of the model predicting in-hospital mortality.

BACKGROUND CONTEXT: Sports-related spinal injuries can be catastrophic in nature. Athletes competing in collision sports (eg, football) may be particularly prone to injury given the high-impact nature of these activities. Due to the oftentimes profound impact of sports-related spinal injuries on health and quality-of-life, they are also associated with a substantial risk of litigation. However, no study to date has assessed litigation risks associated with sports-related spinal injuries. A better understanding of the risk factors surrounding these legal claims may provide insights into injury prevention and other strategies to minimize litigation risks. In addition, it may allow the spine surgeon to better recognize the health, socioeconomic, and legal challenges faced by this patient population. PURPOSE: To provide a comprehensive assessment of reported legal claims involving sports-related spinal injuries, including a comparative analysis of legal outcomes between collision and non-collision sports. To discuss strategies to prevent sports-related spinal injuries and minimize litigation risks. STUDY DESIGN/SETTING: Retrospective review. PATIENT SAMPLE: Athletes experiencing spinal injuries during sports. OUTCOME MEASURES: Outcomes included verdict outcome (defendant vs. plaintiff), legal claims, injuries sustained, clinical symptoms, and award payouts. METHODS: The legal research database Westlaw Edge (Thomson Reuters) was queried for legal claims brought in the United States from 1950 to 2021 involving sports-related spinal injuries. Verdict or settlement outcomes were collected as well as award payouts, time to case closure, case year, and case location. Demographic data, including type of sport (ie collision vs. non-collision sport) and level of play were obtained. Legal claims, spinal injuries sustained, and clinical symptoms were also extracted. Furthermore, the nature of injury, injured spinal region, and treatment pursued were collected. Descriptive statistics were reported for all cases and independent-samples t-tests and chi-square tests were used to compare differences between collision and non-collision sports. RESULTS: Of the 840 cases identified on initial search, 78 met our criteria for in-depth analysis. This yielded 62% (n=48) defendant verdicts, 32% (n=25) plaintiff verdicts, and 6% (n=5) settlements, with a median inflation-adjusted award of $780,000 (range: $5,480-$21,585,000) for all cases. The most common legal claim was negligent supervision (n=38, 46%), followed by premises liability (n=23, 28%), and workers' compensation/no fault litigation (n=10, 12%). The most common injuries sustained were vertebral fractures (n=34, 44%) followed by disc herniation (n=14, 18%). Most cases resulted in catastrophic neurological injury (n=37, 49%), either paraplegia (n=6, 8%) or quadriplegia (n=31, 41%), followed by chronic/refractory pain (n=32, 43%). Non-collision sport cases had a higher percentage of premises liability claims (41% vs. 11%, p=.006) and alleged chronic/refractory pain (53% vs. 28%, p=.04). Conversely, collision sport cases had a higher proportion of workers' compensation/no fault litigation (23% vs. 4%, p=.03) and cases involving disc herniation (29% vs. 9%, respectively; p=.04). CONCLUSION: Sports-related spinal injuries are associated with multiple and complex health, socioeconomic, and legal consequences, with median inflation-adjusted award payouts nearing $800,000 per case. In our cohort, the most commonly cited legal claims were negligent supervision and premises liability, emphasizing the need for prevention guidelines for safe sports practice, especially in non-professional settings. Cases involving athletes participating in non-collision sports were significantly associated with claims citing chronic/refractory pain, highlighting the importance of long-term care in severely injured athletes.

OBJECTIVE: This study aimed to investigate the impact of race on hospital length of stay (LOS) and hospital complications among pediatric patients with cervical/thoracic injury. METHODS: A retrospective cohort was performed using the 2017 admission year from 753 facilities utilizing the National Trauma Data Bank. All pediatric patients with cervical/thoracic spine injuries were identified using the ICD-10-CM diagnosis coding system. These patients were segregated by their race, non-Hispanic white (NHW), non-Hispanic black (NHB), non-Hispanic Asian (NHA), and Hispanic (H). Demographic, hospital variable, hospital complications, and LOS data were collected. A linear and logistic multivariate regression analysis was performed to determine the risk ratio for hospital LOS as well as complication rate, respectively. RESULTS: A total of 4,125 pediatric patients were identified. NHB cohort had a greater prevalence of cervical-only injuries (NHW: 37.39% vs. NHB: 49.93% vs. NHA: 34.29% vs. H: 38.71%, P < 0.001). While transport accident was most common injury etiology for both cohorts, NHB cohort had a greater prevalence of assault (NHW: 1.53% vs. NHB: 17.40% vs. NHA: 2.86% vs. H: 6.58%, P < 0.001) than the other cohorts. Overall complication rates were significantly higher among NHB patients (NHW: 9.39% vs. NHB: 15.12% vs. NHA: 14.29% vs. H: 13.60%, P < 0.001). Compared with the NHW cohort, NHB, NHA, and H had significantly longer hospital LOS (NHW: 6.15 ± 9.03 days vs. NHB: 9.24 ± 20.78 days vs. NHA: 9.09 ± 13.28 days vs. H: 8.05 ± 11.45 days, P < 0.001). NHB race was identified as a significant predictor of increased LOS on multivariate regression analysis (risk ratio: 1.14, 95% confidence interval: 0.46, 1.82; P = 0.001) but not hospital complications (P = 0.345). CONCLUSIONS: Race may significantly impact health care resource utilization following pediatric cervical/thoracic spinal trauma.

Frontal vehicle crashes have been a leading cause of spinal injuries in recent years. Reconstruction of frontal crashes using computational models and spinal load analysis helps us understand the patterns of injury and load propagation during frontal crashes. By reconstructing a real crash test and using a viscoelastic crash dummy model, spinal injury patterns were analyzed. The results indicated that a moderate crash with an impact speed of 56 km/h leads to injuries in L1-L2 and L5-S1 levels (L for lumbar and S for sacral vertebrae). The largest spinal loads and injuries were mainly observed immediately after the airbag deployment when the peak of the crash acceleration transpires. Also, the effects of impulse magnitude on the spinal loads and head injury criterion (HIC) showed that HIC is more sensitive than compressive forces to the magnitude of impulse. Moreover, the effects of disc preconditioning as a major factor in the risk of injury was evaluated. The results demonstrate that as the lumbar spine is subjected to a longer preloading, it will be more vulnerable to injury; preconditioning of the discs more adversely affected the risk of injury than a 10% increase in the crash impulse. Overall the results highlight the importance of spinal injury prevention in frontal crashes.

AIMS: The purpose of this study is to audit the numbers of non-residents requiring orthopaedic admission to Dunedin and Southland Hospitals and determine the effects of increasing tourist numbers on healthcare resources. METHOD: All non-resident orthopaedic admissions to Dunedin Hospital from January 2005 to December 2017 and Invercargill Hospital from January 2011 to December 2017 were analysed with respect to country of residence, mechanism of injury, primary diagnosis and case weights consumed. The results were combined with figures from 1997-2004 to give a 21-year series for Dunedin Hospital. RESULTS: There has been a significant increase in the number of admissions and case weights (CW) over the past 21 years at Dunedin Hospital (p<0.001). The most common mechanisms of injury were snow sports at Dunedin Hospital and falls for Southland Hospital. Between 2011 and 2017 there were on average 50 non-resident admissions per year (92.9 CW/year) to Dunedin Hospital and 74 admissions (120.7 CW/year) in Southland. CONCLUSION: Increasing tourist numbers have resulted in an increase number of orthopaedic admissions to Dunedin Hospital over the last two decades although it remains a small proportion of the total workload. Southland Hospital is relatively more affected. These patients represent an annual cost in excess of $1,000,000 to Southern DHB.

This study aimed to measure the subsequent health and health service cost burden of a cohort of workers hospitalised after sustaining work-related traumatic spinal injuries (TSI) across New South Wales, Australia. A record-linkage study (June 2013-June 2016) of hospitalised cases of work-related spinal injury (ICD10-AM code U73.0 or workers compensation) was conducted. Of the 824 individuals injured during this time, 740 had sufficient follow-up data to analyse readmissions ≤90 days post-acute hospital discharge. Individuals with TSI were predominantly male (86.2%), mean age 46.6 years. Around 8% (n = 61) experienced 119 unplanned readmission episodes within 28 days from discharge, over half with the primary diagnosis being for care involving rehabilitation. Other readmissions involved device complications/infections (7.5%), genitourinary or respiratory infections (10%) or mental health needs (4.3%). The mean ± SD readmission cost was $6946 ± $14,532 per patient. Unplanned readmissions shortly post-discharge for TSI indicate unresolved issues within acute-care, or poor support services organisation in discharge planning. This study offers evidence of unmet needs after acute TSI and can assist trauma care-coordinators' comprehensive assessments of these patients prior to discharge. Improved quantification of the ongoing personal and health service after work-related injury is a vital part of the information needed to improve recovery after major work-related trauma.

OBJECTIVE: Spinal trauma is a major cause of disability worldwide. The burden is especially severe in low-income countries, where hospital infrastructure is poor, resources are limited, and the volume of cases is high. Currently, there are no reliable data available on incidence, management, and outcomes of spinal trauma in East Africa. The main objective of this study was to describe, for the first time, the demographics, management, costs of surgery and implants, treatment decision factors, and outcomes of patients with spine trauma in Tanzania. METHODS: The authors retrospectively reviewed prospectively collected data on spinal trauma patients in the single surgical referral center in Tanzania (Muhimbili Orthopaedic Institute [MOI]) from October 2016 to December 2017. They collected general demographics and the following information: distance from site of trauma to the center, American Spinal Injury Association Impairment Scale (AIS), time to surgery, steroid use, and mechanism of trauma and AOSpine classification and costs. Surgical details and complications were recorded. Primary outcome was neurological status on discharge. The authors analyzed surgical outcome and determined predicting factors for positive outcome. RESULTS: A total of 180 patients were included and analyzed in this study. The mean distance from site of trauma to MOI was 278.0 km, and the time to admission was on average 5.9 days after trauma. Young males were primarily affected (82.8% males, average age 35.7 years). On admission, 47.2% of patients presented with AIS grade A. Most common mechanisms of injury were motor vehicle accidents (28.9%) and falls from height (32.8%). Forty percent of admitted patients underwent surgery. The mean time to surgery was 33.2 days; 21.4% of patients who underwent surgery improved in AIS grade at discharge (p = 0.030). Overall, the only factor associated with improvement in neurological status was undergoing surgery (p = 0.03) and shorter time to surgery (p = 0.02). CONCLUSIONS: This is the first study to describe the management and outcomes of spinal trauma in East Africa. Due to the lack of referral hospitals, patients are admitted late after trauma, often with severe neurological deficit. Surgery is performed but generally late in the course of hospital stay. The decision to perform surgery and timing are heavily influenced by the availability of implants and economic factors such as insurance status. Patients with incomplete deficits who may benefit most from surgery are not prioritized. The authors' results suggest that surgery may have a positive impact on patient outcome. Further studies with a larger sample size are needed to confirm our results. These results provide strong support to implement evidence-based protocols for the management of spinal trauma.

OBJECTIVEWhile blunt spinal trauma accounts for the majority of spine trauma, penetrating injuries affect a substantial number of patients. The goal of this study was to examine the epidemiology of penetrating spine injuries compared with blunt injuries and review the operative interventions and outcomes in the penetrating spine injury group.METHODSThe prospectively maintained trauma database was queried for spinal fractures from 2012 to 2018. Charts from patients with penetrating spine trauma were reviewed.RESULTSA total of 1130 patients were evaluated for traumatic spinal fractures; 154 injuries (13.6%) were secondary to penetrating injuries. Patients with penetrating injuries were significantly younger (29.2 years vs 44.1 years, p < 0.001), more likely male (87.7% vs 69.2%, p < 0.001), and more commonly African American (80.5% vs 33.3%, p < 0.05). When comparing primary insurers, the penetrating group had a significantly higher percentage of patients covered by Medicaid (60.4% vs 32.6%, p < 0.05) or prison (3.9% vs 0.1%, p < 0.05) or being uninsured (17.5% vs 10.3%, p < 0.05). The penetrating group had a higher Injury Severity Score on admission (20.2 vs 15.6, p < 0.001) and longer hospital length of stay (20.1 days vs 10.3 days, p < 0.001) and were less likely to be discharged home (51.3% vs 65.1%, p < 0.05). Of the penetrating injuries, 142 (92.2%) were due to firearms. Sixty-three patients (40.9%) with penetrating injuries had a concomitant spinal cord or cauda equina injury. Of those, 44 (69.8%) had an American Spinal Injury Association Impairment Scale (AIS) grade of A. Ten patients (15.9%) improved at least 1 AIS grade, while 2 patients (3.2%) declined at least 1 AIS grade. Nine patients with penetrating injuries underwent neurosurgical intervention: 5 for spinal instability, 4 for compressive lesions with declining neurological examination results, and 2 for infectious concerns, with some patients having multiple indications. Patients undergoing neurosurgical intervention did not show a significantly greater change in AIS grade than those who did not. No patient experienced a complication directly related to neurosurgical intervention.CONCLUSIONSPenetrating spinal trauma affects a younger, more publicly funded cohort than blunt spinal trauma. These patients utilize more healthcare resources and are more severely injured. Surgery is undertaken for limiting progression of neurological deficit, stabilization, or infection control.

OBJECTIVE: The objective of this study was to investigate the effect of hospital type and patient transfer during the treatment of patients with vertebral fracture and/or spinal cord injury (SCI). METHODS: The National Inpatient Sample (NIS) database was queried to identify patients treated in Utah from 2001 to 2011 for vertebral column fracture and/or SCI (ICD-9-CM codes 805, 806, and 952). Variables related to patient transfer into and out of the index hospital were evaluated in relation to patient disposition, hospital length of stay, mortality, and cost. RESULTS: A total of 53,644 patients were seen (mean [± SEM] age 55.3 ± 0.1 years, 46.0% females, 90.2% white), of which 10,620 patients were transferred from another institution rather than directly admitted. Directly admitted (vs transferred) patients showed a greater likelihood of routine disposition (54.4% vs 26.0%) and a lower likelihood of skilled nursing facility disposition (28.2% vs 49.2%) (p < 0.0001). Directly admitted patients also had a significantly shorter length of stay (5.6 ± 6.7 vs 7.8 ± 9.5 days, p < 0.0001) and lower total charges ($26,882 ± $37,348 vs $42,965 ± $52,118, p < 0.0001). A multivariable analysis showed that major operative procedures (hazard ratio [HR] 1.7, 95% confidence interval [CI] 1.4-2.0, p < 0.0001) and SCI (HR 2.1, 95% CI 1.6-2.8, p < 0.0001) were associated with reduced survival whereas patient transfer was associated with better survival rates (HR 0.4, 95% CI 0.3-0.5, p < 0.0001). A multivariable analysis of cost showed that disposition (ß = 0.1), length of stay (ß = 0.6), and major operative procedure (ß = 0.3) (p < 0.0001) affected cost the most. CONCLUSIONS: Overall, transferred patients had lower mortality but greater likelihood for poor outcomes, longer length of stay, and higher cost compared with directly admitted patients. These results suggest some significant benefits to transferring patients with acute injury to facilities capable of providing appropriate treatment, but also support the need to further improve coordinated care of transferred patients, including surgical treatment and rehabilitation.

BACKGROUND: Among all trauma-related injuries globally, traumatic brain injury (TBI) and traumatic spine injury (TSI) account for the largest proportion of cases. Where previously data was lacking, recent efforts have been initiated to better quantify the extent of neurotrauma in low- and middle-income countries (LMICs). This information is vital to understand the current neurosurgical deficit so that resources and efforts can be focused on where they are needed most. The purpose of this study is to determine the minimum number of neurosurgeons to address the neurotrauma demand in LMICs and evaluate current evidence to support facility needs so that policy-based recommendations can be made to prioritize development initiatives to scale up neurosurgical services. METHODS: Using existing data regarding the incidence of TBI and TSI in LMICs and current neurosurgical workforce and estimates of case load capacity, the minimum number of neurosurgeons needed to address neurotrauma per population was calculated. Evidence was gathered regarding necessary hospital facilities and disbursement patterns based on time needed to intervene effectively for neurotrauma. RESULTS: There are 4,897,139 total operative cases of TBI and TSI combined in LMICs annually. At minimum, there needs to be 1 neurosurgeon only performing neurotrauma cases per approximately 212,000 people. Evidence suggests that patients should be within 4 hours of a neurosurgical facility at the very least. CONCLUSIONS: The development of neurotrauma systems is essential to address the large burden of neurotrauma in LMICs. The minimum requirements for neurosurgical workforce is 1 neurotrauma surgeon per 212,000 people.

This study aimed to describe the epidemiological characteristics, the occupational context, and the cost of hospitalised work-related traumatic spinal injuries, across New South Wales, Australia. A record-linkage study of hospitalised cases of work-related spinal injury (ICD10-AM code U73.0 or workers compensation) was conducted. Study period 2013â»2016. Eight hundred and twenty-four individuals sustained work-related spinal injuries; 86.2% of whom were males and had a mean age of 46.6 years. Falls led to 50% of the injuries; predominantly falls from building/structures, ladders or between levels. Falls occurred predominantly in the construction industry (78%). Transport crashes caused 31% of injuries and 24% in heavy vehicles. Half of all the transport injuries occurred 'off road'. The external cause was coded as 'non-specific work activity' in 44.5% of cases; missing in 11.5%. Acute care bed days numbered at 13,302; total cost $19,500,000. High numbers of work-related spinal injuries occurred in the construction industry; particularly falling from a height. Off-road transport-related injuries were significant and likely unaddressed by 'on-road' prevention policies. Medical record documentation was insufficient in injury mechanism and context specificity. Workers in the construction industry or those using vehicles off-road were at high risk of spinal injury, suggesting inefficient systems approaches or ineffective prevention policies. Reducing the use of non-specific external cause codes in patients' medical records would improve the measurement of policy effectiveness.

BACKGROUND: Subaxial spinal injury surgery is expensive, and its significance is uncertain because of limited rehabilitation and postoperative care. OBJECTIVE: To assess complications and outcome in patients surgically treated for subaxial spinal injuries in 2 hospitals in Addis Ababa, Ethiopia. METHODS: Retrospective study, conducted among 85 patients operated on for subaxial spine injury from January 2013 to August 2016. Data were collected from medical charts. Descriptive statistics and binary logistic regression were used for data analysis. RESULTS: A total of 85 patients were included, and 20 patients were not followed up. The mean age was 33 years (standard deviation ± 12.03 years), and the mean time from injury to surgery was 10 days. The rates of surgical mortality and reoperation were 7.05% and 3.5%, respectively. Deaths occurred in 13 of 16 patients (81.1%) with American Spine Injury Association (ASIA) scores of A and in 3 of 16 patients (18.9%) with ASIA scores of B. The complication rate in patients with a preoperative ASIA score of A was 17/24 (70.8%). The study showed that 55 of 65 patients who were followed up (84.6%; 95% confidence interval [CI]: 75.4, 92.3) experienced improvement. According to the patients' follow-up ASIA scores, 47 (72.3%; 95% CI: 61.5, 83.1) were functional. Sphincter tone before operation (adjusted odds ratio 142.82; 95% CI: 9.973, 204.090) was significantly associated with follow-up ASIA score. CONCLUSIONS: Patients with complete cervical injuries had high rates of mortality and morbidity, indicating that it might be better not to operate on these patients in resource-limited settings. There is a moderate recovery rate in patients with incomplete SCI despite a lack of adequate rehabilitation facilities.

BACKGROUND: Occupational diseases data can guide efforts to improve worker's health and safety. AIMS: To describe MALPROF, the Italian system for surveillance of work-related diseases collected by the subregional Department of Prevention. METHODS: The MALPROF system started in 1999 with contributions from Lombardy and Tuscany and spread in the following years to collect contributions from 14 out of the 20 Italian regions. MALPROF data were explored to follow-up work-related diseases and to detect emerging occupational health risks by calculating proportional reporting ratio (PRR), as in pharmacosurveillance. It classified work-related diseases according to economic sector and job activity in which the exposure occurred. Occupational physicians of the Italian National Health Service evaluate the possible causal relationship with occupational exposures and store the data in a centralized database. RESULTS: From 1999 to 2012, the MALPROF system collected about 112000 cases of workers' diseases. In 2010, more than 13000 cases of occupational diseases were reported. The most frequently reported diseases were hearing loss (n = 4378, 32%), spine disorders (n = 2394, 17%) and carpal tunnel syndrome (n = 1560, 11%). The PRR calculated for cervical disc herniation, a disease whose occupational origin has to be studied, in 1999-2010 was 2.47 [95% confidence interval (CI) 1.76-3.47] for drivers and 36.64 (95% CI 22.03-60.93) for air transport workers. CONCLUSIONS: MALPROF is a sensitive system for identifying possible associations between occupational risks and diseases, it can contribute to the development of preventive measures, to evaluate the effectiveness of preventive interventions and to stimulate research on new occupational risks and diseases.

BACKGROUND CONTEXT: Only Level 3 evidence exists for the diagnosis and treatment of atlantooccipital dislocation (AOD) with few studies examining mortality, neurologic improvement, and patient-reported outcomes (PROs). PURPOSE: First, the aim was to determine: the incidence of AOD, 90-day surgical morbidity and mortality after AOD, patient factors that may be associated with delayed or missed diagnosis, and factors that were associated with mortality and neurologic improvement after AOD. Secondly, the aim was to quantify the pain, disability, and quality of life experienced by patients surviving AOD. STUDY DESIGN/SETTING: This was a retrospective cohort study. PATIENT SAMPLE: A total of 5,337 consecutive spine computed tomography traumagrams from 1997 to 2012 were included. OUTCOME MEASURES: Mortality, neurologic improvement, complications, EuroQol five dimensions (EQ-5D), Neck Disability Index (NDI), Numeric Rating Scale (NRS)-neck, NRS-arm, and return-to-work were the outcome measures. METHODS: Patients were considered to have AOD if they met one of the following radiographic criteria: basion-dens interval greater than 10 mm; basion-axial interval: anterior displacement greater than 12 mm or posterior displacement greater than 4 mm between the basion and posterior C2 line; and condyle to C1 interval greater than 1.4 mm. Linear regression analysis was performed to identify factors associated with 90-day mortality, neurologic improvement, and missed diagnosis. Patient-reported outcomes were assessed via phone interview. RESULTS: Thirty-one patients met radiographic criteria for AOD; an incidence of 0.6% over 15 years. Twenty-one (68%) patients were treated with occipital cervical fusion. At 90 days postoperatively, there were no new neurologic deficits or reoperations. Eight (26%) patients died within 90 days. All patients who died had no documented AOD diagnosis and were not treated surgically. Missed AOD diagnosis was the strongest predictor of mortality. Younger age, lower Glasgow Coma Score, lower Injury Severity Score (ISS) score, and worse initial American Spinal Injury Association (ASIA) score were significantly associated with greater neurologic improvement. Higher ISS score and better ASIA score were significantly associated with missed AOD diagnosis. The average PROs metrics at time of telephone follow-up were as follows: EQ-5D=0.73±0.19, NDI=30.89±18.57, NRS-neck=2.33±2.21, NRS-arm=2.00±2.54. Of the patients with follow-up data, four were employed full-time, and five were receiving disability. CONCLUSIONS: Our work suggests that failure to diagnose AOD is a powerful predictor of mortality. Higher ISS scores and better neurologic presentation were significantly associated with missed diagnosis. Craniocervical arthrodesis preserved neurologic function with low complication rate and unexpectedly high PROs and return-to-work. These results must be carefully interpreted because it is unclear whether missed AOD diagnosis accompanies another death-causing injury (eg, traumatic brain injury) or if failure to treat AOD contributes to mortality in a multifactorial manner.

OBJECT: In the US, race and economic status have pervasive associations with mechanisms of injury, severity of injury, management, and outcomes of trauma. The goal of the current study was to examine these relationships on a large scale in the setting of pediatric spinal injury. METHODS: Admissions for spinal fracture without or with spinal cord injury (SCI), spinal dislocation, and SCI without radiographic abnormality were identified in the Kids' Inpatient Database (KID) and the National Trauma Data Bank (NTDB) registry for 2009. Patients ranged in age from birth up to 21 years. Data from the KID were used to estimate nationwide annual incidences. Data from the NTDB were used to describe patterns of injury in relation to age, race, and payor, with corroboration from the KID. Multiple logistic regression was used to model rates of mortality and spinal fusion. RESULTS: In 2009, the estimated incidence of hospital admission for spinal injury in the US was 170 per 1 million in the population under 21 years of age. The incidence of SCI was 24 per 1 million. Incidences varied regionally. Adolescents predominated. Patterns of injury varied by age, race, and payor. Black patients were more severely injured than patients of other races as measured by Injury Severity Scale scores. Among black patients with spinal injury in the NTDB, 23.9% suffered firearm injuries; only 1% of white patients suffered firearm injuries. The overall mortality rate in the NTDB was 3.9%. In a multivariate analysis that included a large panel of clinical and nonclinical factors, black race retained significance as a predictor of mortality (p = 0.006; adjusted OR 1.571 [1.141-2.163]). Rates of spinal fusion were associated with race and payor in the NTDB data and with payor in the KID: patients with better insurance underwent spinal fusion at higher rates. CONCLUSIONS: The epidemiology of pediatric spinal injury in the US cannot be understood apart from considerations of race and economic status.

BACKGROUND CONTEXT: The influence of nonmedical factors on the disposition of spine trauma patients, initially seen in less specialized institutions, remains an issue of debate. PURPOSE: To investigate the association of lack of insurance and African-American race with the probability of being transferred to a Level I or II trauma center, after being evaluated in the emergency department (ED) of Level III or IV trauma centers for spine trauma. STUDY DESIGN/SETTING: This was a retrospective cohort study. PATIENT SAMPLE: A total of 14,133 patients who were registered in National Trauma Data Bank (NTDB) from 2009 to 2011 and initially evaluated in the ED of Level III or IV trauma centers for spine trauma were included. OUTCOME MEASURES: The outcome measures were rates of transfer to a higher level of care trauma center. METHODS: We performed a retrospective cohort study involving spine trauma patients, who were registered in the NTDB between 2009 and 2011. Regression techniques, controlling for clustering at the hospital level, were used to investigate the association of insurance status and race with the possibility of transfer. RESULTS: Overall, 4,142 patients (29.31%) were transferred to a higher level of care institution, and 9,738 (70.69%) were admitted to a Level III or IV trauma center. Multivariable logistic regression analysis demonstrated an association of uninsured patients with increased possibility of transfer (odds ratio [OR], 1.40; 95% confidence interval [CI], 1.22-1.61). This persisted after using a mixed effects model to control for clustering at the hospital level (OR, 1.65; 95% CI, 1.37-1.96). African-American race was not associated with the decision to transfer, when using a mixed effects model (OR, 1.15; 95% CI, 0.89-1.48). However, African-Americans with Glasgow Coma Scale greater than 8 (OR, 1.40; 95% CI, 1.13-1.74) or Injury Severity Score less than 15 (OR, 1.54; 95% CI, 1.21-1.96) were associated with a higher likelihood of transfer. CONCLUSIONS: In summary, lack of insurance was associated with increased possibility of transfer to higher level of care institutions, after evaluation in a Level III or IV trauma center ED for spine trauma. The same was true for African-Americans with milder injuries.

BACKGROUND: Seat belt use is the single most effective way to save lives and reduce injuries in motor vehicle crashes. However, some case reports described seat belt use as a double-edged sword because some injuries are related to seat belt use in motor vehicle crashes. To comprehensively understand the effects of seat belt use, we systemically investigated the association between seat belt use and injuries based on anatomic body region and type of injury in drivers involved in motor vehicle crashes. METHODS: The injury information was obtained by linking crash reports with hospital discharge data and categorized by using the diagnosis codes based on the Barell injury diagnosis matrix. A total of 10,479 drivers (≥15 years) in passenger vehicles involved in motor vehicle crashes from 2006 to 2011 were included in this study. RESULTS: Seat belt use significantly reduced the proportions of traumatic brain injury (10.4% non-seat belt; 4.1% seat belt) and other head, face, and neck injury (29.3% non-seat belt; 16.6% seat belt) but increased the proportion of spine: thoracic to coccyx injury (17.9% non-seat belt; 35.5% seat belt). Although the proportion of spine: thoracic to coccyx injury was increased in drivers with seat belt use, the severity of injury was decreased, such as fracture (4.2% with seat belt use; 22.0% without seat belt use). Furthermore, the total medical charges decreased due to the change of injury profiles in drivers with seat belt use from a higher percentage of fractures (average cost for per case $26,352) to a higher percentage of sprains and/or strains ($1,897) with spine: thoracic to coccyx injury. CONCLUSION: This study provide a comprehensive picture for understanding the protective effect of seat belt use on injuries based on anatomic body region and type of injury in drivers involved in motor vehicle crashes.

BACKGROUND: Spine trauma patients may represent a group for whom insurance fails to provide protection from catastrophic medical expenses, resulting in the transfer of financial burden onto individual families and public payers. This study compares the rate of insurance discontinuation for patients who underwent surgery for traumatic spine injury with and without spinal cord injury with the rate for matched control subjects. METHODS: We used the MarketScan database to perform a retrospective cohort study of privately insured spine trauma patients who underwent surgery from 2006 to 2010. Kaplan-Meier survival analysis was used to assess the time to insurance discontinuation. Cox proportional-hazards regression was used to determine hazard ratios for insurance discontinuation among spine trauma patients compared with the matched control population. RESULTS: The median duration of existing insurance coverage was 20.2 months for those with traumatic spinal cord injury, 25.6 months for those with traumatic spine injury without spinal cord injury, and 48.0 months for the matched control cohort (log-rank p < 0.0001). After controlling for multiple covariates, the hazard ratios for discontinuation of insurance were 2.02 (95% CI [confidence interval], 1.83 to 2.23) and 2.78 (95% CI, 2.31 to 3.35) for the trauma patients without and with spinal cord injury, respectively, compared with matched controls. CONCLUSIONS: Rates of insurance discontinuation are significantly higher for trauma patients with severe spine injury compared with the uninjured population, indicating that patients with disabling injuries are at increased risk for loss of insurance coverage.
