Secondary neurological deterioration in traumatic spinal injury: data from medicolegal cases

Practices of Adult Spine Immobilization During Trauma Resuscitation: Proposal for Improved Guidelines

INTRODUCTION

This narrative review aims to evaluate the impact of current spinal immobilization practices on clinical outcomes in adult trauma patients with suspected or confirmed spinal injury to direct the creation of improved practice management guidelines.

METHODS

PubMed, ProQuest, Embase, Google Scholar, and Cochrane were searched for studies that evaluated the impact of spine immobilization practices during resuscitation in adult trauma patients and reported associated clinical outcomes. Outcomes included neurological deficits, in-hospital mortality, hospital length of stay (HLOS), ICU length of stay (ICU-LOS), discharge disposition, long-term functional status (modified Rankin scale), vascular injury rate, and respiratory injury rate.

RESULTS

Nine studies were included in this review, divided into two groups based on patient immobilization status. Patients compared with and without cervical immobilization had higher mortality, longer ICU-LOS, and a higher incidence of neurological deficits if immobilized. Immobilization only was associated with a higher incidence of indirect neurological injury and poor functional outcomes.

CONCLUSION

Spinal immobilization during resuscitation in adult trauma patients is associated with a higher risk of neurological injury, in-hospital mortality, and longer ICU-LOS. Further research is needed to provide strong evidence for spinal immobilization guidelines and identify the optimal method and timing for immobilization practices in trauma patients.

The Immo Traffic Light System as a Decision-Making Tool for Prehospital Spinal Immobilization

BACKGROUND

Spinal injuries are difficult injuries to assess yet can be associated with significant neurological damage. To avoid secondary damage, immobilization is considered state of the art trauma care. The indication for spinal immobilization must be assessed, however, for potential complications as well as its advantages and disadvantages.

METHODS

This systematic review addressing the question of the correct indication for spinal immobilization in trauma patients was compiled on the basis of our previously published analysis of possible predictors from the Trauma Registry of the German Society for Trauma Surgery. A Delphi procedure was then used to develop suggestions for action regarding immobilization based on the results of this review.

RESULTS

The search of the literature yielded 576 publications. The 24 publications included in the qualitative analysis report of 2 228 076 patients. A decision tool for spinal immobilization in prehospital trauma care was developed (Immo traffic light system) based on the results of the Delphi procedure. According to this system, severely injured patients with blunt trauma, severe traumatic brain injury, peripheral neurological symptoms, or spinal pain requiring treatment should be immobilized. Patients with a statistically increased risk of spinal injury as a result of the four cardinal features (fall >3m, severe trunk injury, supra clavicular injury, seniority [age >65 years]) should only have their spinal motion restricted after weighing up the pros and cons. Isolated penetrating trunk injuries should not be immobilized.

CONCLUSION

High-quality studies demonstrating the benefit of prehospital spinal immobilization are still lacking. Decision tools such as the Immo traffic light system can help weigh up the pros and cons of immobilization.

Magnetic resonance imaging cervical spine in trauma: A retrospective single-centre audit of patient outcomes

OBJECTIVE

Magnetic resonance imaging (MRI) is often used in practice to investigate for cord or discoligamentous injury following blunt trauma and a normal computed tomography (CT). This study investigates the MRI findings and surgical outcomes of patients in this cohort.

METHODS

Retrospective analysis of patients following trauma with suspected cervical spine injury from 2016 to 2019. Inclusion criteria included patients receiving a normal CT of the cervical spine and subsequent MRI due to cervical spine injury symptomatology (persistent tenderness and/or neurology). Inclusion criteria included: age ≥16 years, alert and <72 h from CT to MRI. Mann-Whitney and χ2 statistical analysis techniques were employed.

RESULTS

Two hundred and twenty-eight patients with persistent midline tenderness and/or persistent neurology following blunt trauma and negative CT report were included. One hundred and eighty-one patients received an MRI for persistent tenderness of which 35 revealed abnormal MRI findings. Twenty-one cases required no treatment, 14 cases were treated with a rigid collar with no patients requiring operative management. Forty-seven patients received an MRI for neurological symptoms following blunt trauma and negative CT, with 11 abnormal MRI findings. Management included no treatment (three cases), application of rigid collar (six cases) and operative management (two cases).

CONCLUSION

No alert neurologically intact patient with 'persistent tenderness only' received operative management following a normal CT examination. While MRI is sensitive for detecting soft tissue injuries, the prevalence for detecting clinically significant cervical spine injury in blunt trauma patients in the absence of neurology is low. The utility of MRI in this cohort is questionable considering prolonged spinal immobilisation is not without harm.

A survey on the early management of spinal trauma in low and middle-income countries: From the scene of injury to the diagnostic phase (part II)

•

Most spinal trauma worldwide occurs in low-and middle-income countries (LMICs). Several factors may limit the applicability of current guidelines as regards the early management of spinal injury.

•

The pre-hospital management per se of spinal trauma in LMICs is subject to partial adherence to recommendations, with possible impact on patient outcomes.

•

The use of clinical (eg ASIA) and morphological (eg SLIC, TLICS, AO Spine) grading scales is not homogeneous.

•

The availability and cost of diagnostic equipment, and the timing of emergency imaging can vary significantly from one region to another, probably affecting the timely management of spinal injury patients.

•

The introduction of resource-targeted guidelines for spinal trauma may be a valuable option to overcome the limitations of real-life application of current guidelines.

Clinical significance of "positive" cervical spine MRI findings following a negative CT

PURPOSE

To review and analyze the clinical significance of positive acute traumatic findings seen on MRI of the cervical spine (MRCS) following a negative CT of the cervical spine (CTCS) for trauma.

METHODS

We performed a sub-cohort analysis of 54 patients with negative CTCS and a positive MRCS after spine trauma from the previous multicenter study of the Research Consortium of New England Centers for Trauma (ReCONECT). Both CTCS and MRCS were independently reviewed by two emergency radiologists and two spine surgeons. The surgeons also commented on the clinical significance of the traumatic findings seen on MRCS and grouped them into unstable, potentially unstable, and stable injuries.

RESULTS

Among 35 unevaluable patients, MRCS showed one unstable (hyperextension) and two potentially unstable (hyperflexion) injuries. Subtle findings were seen on CTCS in 2 of 3 patients upon careful retrospective review that would have suggested these injuries. Of 19 patients presenting with cervicalgia, 2/5 (40%) patients with neurological deficit demonstrated clinically significant findings on MRCS with predisposing factors seen on CT. None of the 14 patients with isolated cervicalgia and no neurological deficit had clinically significant findings on their MRCS.

CONCLUSION

While CTCS is adequate for clearing the cervical spine in patients with isolated cervicalgia, MRCS can play a critical role in patients with neurological deficits and normal CTCS. Clinically significant traumatic findings were seen in 8.5% of unevaluable patients on MRCS, though these injuries in fact could be identified on the CT in 2 of 3 patients upon careful retrospective review.

Rapid and effective treatment of traumatic spinal cord injury using stem cell derived exosomes

Traumatic spinal cord injury is a fatal acute event without effective clinical therapies. Following the trauma, immediate neural protection and microenvironment mitigation are vitally important for nerve tissue repair, where stem cell-based therapies could be eclipsed by the deficiency of cells due to the hostile microenvironment as well as the transport and preservation processes. Effective emergency strategies are required to be convenient, biocompatible, and stable. Herein, we assess an emergency cell-free treatment using mesenchymal stem cell-derived exosomes, which have proven capable of comprehensive mitigation of the inhibitory lesion microenvironment. The clinically validated fibrin glue is utilized to encapsulate the exosomes and in-situ gelates in transected rat spinal cords to provide a substrate for exosome delivery as well as nerve tissue growth. The emergency treatment alleviates the inflammatory and oxidative microenvironment, inducing effective nerve tissue repair and functional recovery. The therapy presents a promising strategy for effective emergency treatment of central nervous system trauma.

An observation of the clinical efficacy of combining Riluzole with mannitol and hyperbaric oxygen in treating acute spinal cord injury

Objective:

To examine the clinical efficacy of combining Riluzole with mannitol and hyperbaric oxygen therapy in treating thoracolumbar vertebral fracture-induced acute spinal cord injury (ASCI).

Methods:

From June 2015 to May 2018, 80 patients with thoracolumbar fractures and ASCI who were treated at Baoding First Central Hospital were selected. All patients underwent posterior laminectomy and screw fixation, and they were randomly divided into two groups using a random number table method. The control group received conventional postoperative treatment, while the experimental group was treated with riluzole combined with mannitol and hyperbaric oxygen on the basis of conventional treatment. The recovery of nerve function which included motor function and sensory function, and the changes of serum IL-6, CRP, BDNF, BFGF and other factors before treatment and four weeks after treatment of the two groups of patients were observed and evaluated.

Results:

After treatment, the motor function scores and sensory function scores of the two groups of patients were improved compared with those before treatment (p<0.05). Compared with the control group, the experimental group improved significantly, and the difference was statistically significant (p<0.05). The levels of IL-6, BDNF and NFGF in the experimental group were significantly lower than those in the control group (p<0.05).

Conclusions:

For patients with thoracolumbar fractures and ASCI undergoing laminar decompression and fixation, the comprehensive treatment plan of riluzole combined with mannitol and hyperbaric oxygen has certain advantages. Compared with the conventional therapy, it may significantly improve the movement and sensory functions of patients, relieve the inflammatory response of spinal cord, and promote recovery from the injury.

Multiple trauma management in mountain environments - a scoping review : Evidence based guidelines of the International Commission for Mountain Emergency Medicine (ICAR MedCom). Intended for physicians and other advanced life support personnel

Background

Multiple trauma in mountain environments may be associated with increased morbidity and mortality compared to urban environments.

Objective

To provide evidence based guidance to assist rescuers in multiple trauma management in mountain environments.

Eligibility criteria

All articles published on or before September 30th 2019, in all languages, were included. Articles were searched with predefined search terms.

Sources of evidence

PubMed, Cochrane Database of Systematic Reviews and hand searching of relevant studies from the reference list of included articles.

Charting methods

Evidence was searched according to clinically relevant topics and PICO questions.

Results

Two-hundred forty-seven articles met the inclusion criteria. Recommendations were developed and graded according to the evidence-grading system of the American College of Chest Physicians. The manuscript was initially written and discussed by the coauthors. Then it was presented to ICAR MedCom in draft and again in final form for discussion and internal peer review. Finally, in a face-to-face discussion within ICAR MedCom consensus was reached on October 11th 2019, at the ICAR fall meeting in Zakopane, Poland.

Conclusions

Multiple trauma management in mountain environments can be demanding. Safety of the rescuers and the victim has priority. A crABCDE approach, with haemorrhage control first, is central, followed by basic first aid, splinting, immobilisation, analgesia, and insulation. Time for on-site medical treatment must be balanced against the need for rapid transfer to a trauma centre and should be as short as possible. Reduced on-scene times may be achieved with helicopter rescue. Advanced diagnostics (e.g. ultrasound) may be used and treatment continued during transport.

French recommendations for the management of patients with spinal cord injury or at risk of spinal cord injury

OBJECTIVES

To update the French guidelines on the management of trauma patients with spinal cord injury or suspected spinal cord injury.

DESIGN

A consensus committee of 27 experts was formed. A formal conflict-of-interest (COI) policy was developed at the outset of the process and enforced throughout. The entire guidelines process was conducted independently of any industrial funding (i.e. pharmaceutical, medical devices). The authors were advised to follow the rules of the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) system to guide assessment of quality of evidence. The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasised.

METHODS

The committee studied twelve questions: (1) What are the indications and arrangements for spinal immobilisation? (2) What are the arrangements for pre-hospital orotracheal intubation? (3) What are the objectives of haemodynamic resuscitation during the lesion assessment, and during the first few days in hospital? (4) What is the best way to manage these patients to improve their long-term prognosis? (5) What is the place of corticosteroid therapy in the initial phase? (6) What are the indications for magnetic resonance imaging in the lesion assessment phase? (7) What is the optimal time for surgical management? (8) What are the best arrangements for orotracheal intubation in the hospital environment? (9) What are the specific conditions for weaning these patients from mechanical ventilation for? (10) What are the procedures for analgesic treatment of these patients? (11) What are the specific arrangements for installing and mobilising these patients? (12) What is the place of early intermittent bladder sampling in these patients? Each question was formulated in a PICO (Patients, Intervention, Comparison, Outcome) format and the evidence profiles were produced. The literature review and recommendations were made according to the GRADE® Methodology.

RESULTS

The experts' work synthesis and the application of the GRADE method resulted in 19 recommendations. Among the recommendations formalised, 2 have a high level of evidence (GRADE 1+/-) and 12 have a low level of evidence (GRADE 2+/-). For 5 recommendations, the GRADE method could not be applied, resulting in expert advice. After two rounds of scoring and one amendment, strong agreement was reached on all the recommendations.

CONCLUSIONS

There was significant agreement among experts on strong recommendations to improve practices for the management of patients with spinal cord injury.

EPIDEMIOLOGICAL ANALYSIS OF SPINAL CORD INJURY IN THE CITY OF JOINVILLE (SC)

ABSTRACT Objective This paper proposes a retrospective analysis of the spinal cord trauma at a regional hospital that is a Unified Health System (SUS) reference in Orthopedics and Traumatology, considering epidemiological data and comparing treatments and hospitalization costs. Methods This study is a retrospective, analytical-descriptive, exploratory documental analysis, using data from the medical records of patients treated for spinal cord trauma during 2016 at the São José Municipal Hospital (Joinville, SC). Results Twenty-three patients were included in the study, 20 of whom (87%) were male. As to etiology, traffic accidents accounted for 47.8% of the cases and gunshot wounds were in second place with 26.1% of the injuries. The correlation between the cost of hospitalization and the days of hospitalization was statistically significant (p = 0.013), as was the correlation between the cost of hospitalization and the number of procedures (p = 0.000). Conclusions Surgical treatment demands greater amounts of financial and human resources. The purpose of this study is to provide local epidemiological data to encourage discussion about other studies, as well as planning for resource allocation and public policy. Level of evidence II; Retrospective Study.

Identifying Predictors of Higher Acute Care Costs for Patients With Traumatic Spinal Cord Injury and Modeling Acute Care Pathway Redesign: A Record Linkage Study

STUDY DESIGN

Record linkage study using healthcare utilization and costs data.

OBJECTIVE

To identify predictors of higher acute-care treatment costs and length of stay for patients with traumatic spinal cord injury (TSCI).

SUMMARY OF BACKGROUND DATA

There are few current or population-based estimates of acute hospitalization costs, length of stay, and other outcomes for people with TSCI, on which to base future planning for specialist SCI health care services.

METHODS

Record linkage study using healthcare utilization and costs data; all patients aged more than or equal to 16 years with incident TSCI in the Australian state of New South Wales (June 2013-June 2016). Generalized Linear Model regression to identify predictors of higher acute care treatment costs for patients with TSCI. Scenario analysis quantified the proportionate cost impacts of patient pathway modification.

RESULTS

Five hundred thirty-four incident cases of TSCI (74% male). Total cost of all acute index episodes approximately AUD$40.5 (95% confidence interval [CI] ±4.5) million; median cost per patient was AUD$45,473 (Interquartile Range: $15,535-$94,612). Patient pathways varied; acute care was less costly for patients admitted directly to a specialist spinal cord injury unit (SCIU) compared with indirect transfer within 24 hours. Over half (53%) of all patients experienced at least one complication during acute admission; their care was less costly if they had been admitted directly to SCIU. Scenario analysis demonstrated that a reduction of indirect transfers to SCIU by 10% yielded overall cost savings of AUD$3.1 million; an average per patient saving of AUD$5,861.

CONCLUSION

Direct transfer to SCIU for patients with acute TSCI resulted in lower treatment costs, shorter length of stay, and less costly complications. Modeling showed that optimizing patient-care pathways can result in significant acute-care cost savings. Reducing potentially preventable complications would further reduce costs and improve longer-term patient outcomes.

Heterogeneous emergency department management of published recommendation defined hypotension in patients with acute traumatic spinal cord injury: A multi-centre overview

OBJECTIVE

Evidence-based management for patients with acute traumatic spinal cord injury (TSCI) in the ED has a critical impact on long-term outcomes. Acute hypotension post-injury may compromise spinal cord perfusion and extend neurological damage. Published guidelines recommend mean arterial blood pressure (BP) maintenance between 85 and 90 mmHg for 7 days post-injury; the extent to which this is followed in Australia is unknown.

METHODS

Prospective observational study of patients ≥16 years with TSCI, treated at 48 hospitals across two Australian states. Mean arterial BPs were recorded in the Ambulance, and ED arrival and discharge. Patients' medical records documented treatment provided (intravenous fluids, vasopressors or both) for BP augmentation. Hypotension was defined as mean arterial BP <85 mmHg, per the American Association of Neurological Surgeons guidelines.

RESULTS

The 208 patients with TSCI in the present study were more likely to receive BP augmentation if they experienced direct transport to a Spinal Cord Service hospital (OR 5.57, 95% CI 2.32-10.11), had a cervical level injury (OR 2.32, 95% CI 1.01-5.5) or were hypotensive on ED arrival (OR 2.42, 95% CI 1.34-4.39). Of the 112 patients who were hypotensive, 71 (63.4%) received treatment for this; however, the majority (76%) remained hypotensive on discharge.

CONCLUSION

Hypotensive patients' post-TSCI experienced heterogeneous ED care discordant with published guidelines; varying by hospital type. Specialist care and more severe injury increased likelihood of guideline adherence. Lack of adherence may influence patient outcomes. Level 1 evidence is needed along with consistent guideline implementation and clinician training to likely improve TSCI management and outcomes.

Traumatic hyperextension-distraction injuries of the thoracolumbar spine: a technical note on surgical positioning

PURPOSE

Hyperextension-distraction type injury of the thoracolumbar spine is an unstable fracture pattern that generally necessitates surgical stabilization by posterior instrumentation. Care must be taken when positioning these patients from supine to prone due to the unstable nature of their injury. The study objectives were (1) to describe a novel modification of the Jackson table turn technique, which may be safer and more effective than the conventional log-roll method and traditional Jackson table technique for positioning patients with hyperextension-distraction injuries of the thoracolumbar spine from supine to prone in the operating room and (2) to present two cases in which this technique was successfully performed.

METHODS

Two patients were carefully positioned from supine to prone by our modification of the Jackson table turn technique, which utilizes a Wilson frame sandwiched between two flat-top Jackson frames. Case 1: a 65-year-old female presented status-post motor vehicle collision with a T9-T10 extension-distraction injury, requiring T7-T12 posterior spinal instrumented fusion (PSIF). Case 2: a 72-year-old female presented status-post motor vehicle collision with a T9-T10 extension-distraction injury and an unstable L1 burst fracture, requiring T7-L2 PSIF.

RESULTS

Both patients remained hemodynamically stable and neurologically intact throughout positioning and postoperatively.

CONCLUSIONS

This technique is safe and effective for positioning patients with hyperextension-distraction type injuries of the thoracolumbar spine from supine to prone in the operating room and may be superior to conventional methods. These slides can be retrieved under Electronic Supplementary Material.

Emergency and acute care management of traumatic spinal cord injury: a survey of current practice among senior clinicians across Australia

Background

To describe pre-hospital, emergency department and acute care assessment and management practices of senior clinicians for patients with acute traumatic spinal cord injury (TSCI) across Australia; and to describe clinical practice variation.

Methods

We used a descriptive, cross-sectional study design to survey senior clinicians (greater than 10 years practice in this field) caring for patients with acute TSCI. The assessment, management and referral practices of prehospital, emergency department/trauma and surgical expert clinicians, across prehospital, early hospital care, diagnostic imaging and haemodynamic management were surveyed.

Results

We invited 95 eligible senior clinicians; the response rate was 75%. Survey findings demonstrated overall lack of awareness or consistent use of evidence based published guidelines; many clinicians following ‘locally written’ or ‘no particular’ guideline. Practitioners were conflicted across multiple areas including patient assessment and diagnosis, treatment and transport decisions. Reported spinal immobilisation practices differed substantially, as did target setting for blood pressure; the majority of clinicians actively monitored risk of respiratory deterioration. Specialist care consult and specialist service bed availability was reported as problematic by more than one third of clinicians.

Conclusions

Unwarranted clinical practice variation is known to contribute to different health outcomes for patients with similar etiologies. Clinical practice guidelines offer evidence based, best practice standards, however are only effective if adopted throughout the healthcare system. Wide variability in acute care practices, pathways and timing to specialist centres for TSCI was evidenced by this survey despite seniority among clinicians. This devastating injury requires prompt, consistent, evidence based care from the moment of first responder. Improved outcomes for patients with TSCI would be more likely with standardised care across pre-hospital, emergency and acute care phases of care.

A New Craniothoracic Mattress for Immobilization of the Cervical Spine in Critical Care Patients

Current immobilization techniques of the cervical spine are associated with complications including pressure ulcers, discomfort, and elevated intracranial pressures with limited access to the thorax and airway. In this study, a newly developed craniothoracic immobilizer (Pharaoh mattress) for critical care patients with cervical injury was tested for its restriction of cervical movement, peak interface pressures, comfort, and radiolucency, and compared with headblocks strapped to a spineboard. Cervical movement was measured by roentgen stereophotogrammetric analysis in 5 fresh frozen cadavers. Peak interface and discomfort pressures were measured in 10 healthy volunteers. Radiographic absorption was calculated by measuring the total emission radiation with and without immobilizer. The Pharaoh mattress caused a mean restriction of 59% (SD: 15) flexion-extension, 77% (SD: 14) lateral bending, and 93% (SD: 3) rotation, compared with the unrestricted situation. No significant differences in restriction of cervical movement were found between headblocks strapped to a spineboard and the Pharaoh mattress. The mean peak pressures on the Pharaoh mattress were significantly lower than on the spineboard. Healthy volunteers gave significantly lower numeric discomfort scores on the Pharaoh mattress than on the spineboard. The Pharaoh mattress absorbed more x-rays than the spineboard. The Pharaoh mattress provides similar restriction of cervical movement compared with headblocks strapped to a spineboard but with lower interface pressures and increased comfort. This new mattress could be useful for immobilization of the cervical spine in critical care patients with mechanically instable spinal fractures.

The pathologic mechanisms underlying lumbar distraction spinal cord injury in rabbits

BACKGROUND CONTEXT

A reliable experimental rabbit model of distraction spinal cord injury (SCI) was established to successfully simulate gradable and replicable distraction SCI. However, further research is needed to elucidate the pathologic mechanisms underlying distraction SCI.

PURPOSE

The aim of this study was to investigate the pathologic mechanisms underlying lumbar distraction SCI in rabbits.

STUDY DESIGN

This is an animal laboratory study.

METHODS

Using a self-designed spine distractor, the experimental animals were divided into a control group and 10%, 20%, and 30% distraction groups. Pathologic changes to the spinal cord microvessels in the early stage of distraction SCI were identified by perfusion of the spinal cord vasculature with ink, production of transparent specimens, observation by light microscopy, and observation of corrosion casts of the spinal cord microvascular architecture by scanning electron microscopy. Malondialdehyde (MDA) and superoxide dismutase (SOD) concentrations in the injured spinal cord tissue were measured after 8 hours.

RESULTS

With an increasing degree and duration of distraction, the spinal cord microvessels were only partially filled and had the appearance of spasm until rupture and hemorrhage were observed. The MDA concentration increased and the SOD concentration decreased in the spinal cord tissue.

CONCLUSIONS

Changes to the internal and external spinal cord vessels led to spinal cord ischemia, which is a primary pathologic mechanism of distraction SCI. Lipid peroxidation mediated by free radicals took part in secondary pathologic damage of distraction SCI.

Risk factors for 14-day rehospitalization following trauma with new traumatic spinal cord injury diagnosis: A 10-year nationwide study in Taiwan

Objectives

Fourteen-day rehospitalization with new traumatic spinal cord injury (tSCI) diagnosis is used as an indicator for the diagnostic quality of the first hospitalization. In this nationwide population-based cohort study, we identified risk factors for this indicator.

Methods

We conducted a nested case–control study by using the data of patients who received a first hospitalization for trauma between 2001 and 2011. The data were retrieved from Taiwan’s National Health Insurance Research Database. Variables including demographic and trauma characteristics were compared between patients diagnosed with tSCI at the first hospitalization and those receiving a 14-day rehospitalization with new tSCI diagnosis.

Results

Of the 23 617 tSCI patients, 997 had 14-day rehospitalization with new tSCI diagnosis (incidence rate, 4.22%). The risk of 14-day rehospitalization with new tSCI diagnosis was significantly lower in patients with severe (injury severity score [ISS] = 16–24; odds ratio [OR], 0.17; 95% confidence interval [CI], 0.13–0.21) and profound (ISS > 24; OR, 0.11; 95% CI, 0.07–0.18) injuries. Interhospital transfer (OR, 8.20; 95% CI, 6.48–10.38) was a significant risk factor, along with injuries at the thoracic (OR, 1.62; 95% CI, 1.21–2.18), lumbar (OR, 1.30; 95% CI, 1.02–1.65), and multiple (OR, 3.23; 95% CI, 1.86–5.61) levels. Brain (OR, 2.82), chest (OR, 2.99), and abdominal (OR, 2.74) injuries were also identified as risk factors. In addition, the risk was higher in patients treated at the orthopedic department (OR, 2.26; 95% CI, 1.78–2.87) and those of other surgical disciplines (OR, 1.89; 95% CI, 1.57–2.28) than in those treated at the neurosurgery department.

Conclusions

Delayed tSCI diagnoses are not uncommon, particularly among trauma patients with ISSs < 16 or those who are transferred from lower-level hospitals. Further validation and implementation of evidence-based decision rules is essential for improving the diagnostic quality of traumatic thoracolumbar SCI.

Cervical collars and immobilisation: A South African best practice recommendation

INTRODUCTION

The consequences of spinal injury as a result of trauma can be devastating. Spinal immobilisation using hard trauma boards and rigid cervical collars has traditionally been the standard response to suspected spinal injury patients even though the risk may be extremely low. Recently, adverse events due to the method of immobilisation have challenged the need for motion restriction in all trauma patients. International guidelines have been published for protection of the spine during transport and this article brings those guidelines into the South African context.

RECOMMENDATIONS

Trauma patients need to be properly assessed using both an approved list of high and low risk factors, as well as a thorough examination. They should then be managed accordingly. Internationally validated assessment strategies have been developed, and should be used as part of the patient assessment. The method of motion restriction should be selected to suit the situation. The use of a vacuum mattress is the preferable technique, with the use of a trauma board being the least desirable.

CONCLUSION

The need for motion restriction in suspected spinal injury should be properly evaluated and appropriate action taken. Not all trauma patients require spinal motion restriction.

Improving care standards for patients with spinal trauma combining a modified e-Delphi process and stakeholder interviews: a study protocol

INTRODUCTION

Around 300 people sustain a new traumatic spinal cord injury (TSCI) in Australia each year; a relatively low incidence injury with extremely high long-term associated costs. Care standards are inconsistent nationally, lacking in consensus across important components of care such as prehospital spinal immobilisation, timing of surgery and timeliness of transfer to specialist services. This study aims to develop 'expertly defined' and agreed standards of care across the majority of disciplines involved for these patients.

METHODS AND ANALYSIS

A modified e-Delphi process will be used to gain consensus for best practice across specific clinical early care areas for the patient with TSCI; invited participants will include clinicians across Australia with relevant and significant expertise. A rapid literature review will identify available evidence, including any current guidelines from 2005 to 2015. Level and strength of evidence identified, including areas of contention, will be used to formulate the first round survey questions and statements. Participants will undertake 2-3 online survey rounds, responding anonymously to questionnaires regarding care practices and indicating their agreement or otherwise with practice standard statements. Relevant key stakeholders, including patients, will also be interviewed face to face.

ETHICS AND DISSEMINATION

Ethics approval for this study was obtained by the NSW Population & Health Services Research Ethics Committee on 14 January 2016 (HREC/12/CIPHS/74). Seeking comprehensive understanding of how the variation in early care pathways and treatment can be addressed to achieve optimal patient outcomes and economic costs; the overall aim is the agreement to a consistent approach to the triage, treatment, transport and definitive care of acute TSCI victims. The agreed practice standards of care will inform the development of a Clinical Pathway with practice change strategies for implementation. These standards will offer a benchmark for state-wide and potentially national policy.

The Norwegian guidelines for the prehospital management of adult trauma patients with potential spinal injury

The traditional prehospital management of trauma victims with potential spinal injury has become increasingly questioned as authors and clinicians have raised concerns about over-triage and harm. In order to address these concerns, the Norwegian National Competence Service for Traumatology commissioned a faculty to provide a national guideline for pre-hospital spinal stabilisation. This work is based on a systematic review of available literature and a standardised consensus process. The faculty recommends a selective approach to spinal stabilisation as well as the implementation of triaging tools based on clinical findings. A strategy of minimal handling should be observed.

Does Every Patient Require Imaging after Cervical Spine Trauma? A Knowledge Translation Project to Support Evidence-Informed Practice for Physiotherapists

Purpose: This article evaluates, describes, and addresses a gap in British Columbia physiotherapists' knowledge of the decision making required for the diagnostic imaging of patients after traumatic neck injury. Method: An online survey of orthopaedic physiotherapists in British Columbia was undertaken to explore their awareness of, knowledge of, and attitudes toward the Canadian Cervical Spine Rule (C-Spine Rule) and decision making regarding the need for diagnostic imaging in managing patients with traumatic neck injury. The survey included questions about managing clinical scenarios; respondents' awareness, knowledge, and use of a specific clinical decision rule-the C-Spine Rule-and any perceived barriers to using clinical practice guidelines in general and the C-Spine Rule in specific. The survey also included questions about the facilitators of and barriers to using the C-Spine Rule. These data were used to guide development of a tool kit to facilitate use of the rule. Results: Of 889 physiotherapists, 467 (52.5%) completed the survey. Given a scenario in which imaging was indicated according to the C-Spine Rule, 95.2% of the respondents correctly recommended imaging. However, in a scenario in which imaging was not indicated, 42.7% incorrectly recommended it. The barriers to using the guidelines included their perceived rigidity, role limitation, and reliance on clinical judgment. The results indicated a need for, and guided development of, resources to facilitate the use of the C-Spine Rule by British Columbia physiotherapists. Conclusions: We identified a gap in the knowledge of British Columbia physiotherapists in identifying which patients were most likely to require imaging after sustaining a traumatic neck injury. We developed a tool kit to address these barriers. British Columbia physiotherapists have accessed this resource extensively. Evaluating its impact on clinical practice, although desirable, was not feasible.

Utility of MRI for cervical spine clearance after blunt traumatic injury: a meta-analysis

OBJECTIVES

To quantify the rate of unstable injuries detected by MRI missed on CT in blunt cervical spine (CS) trauma patients and assess the utility of MRI in CS clearance.

METHODS

We undertook a systematic review of worldwide evidence across five major medical databases and performed a meta-analysis. Studies were included if they reported the number of unstable injuries or gave enough details for inference. Variables assessed included severity, CT/MRI specifications, imaging timing, and outcome/follow-up. Pooled incidences of unstable injury on follow-up weighted by inverse-of-variance among all included and obtunded or alert patients were reported.

RESULTS

Of 428 unique citations, 23 proved eligible, with 5,286 patients found, and 16 unstable injuries reported in five studies. The overall pooled incidence is 0.0029 %. Among studies reporting only obtunded patients, the pooled incidence is 0.017 %. In alert patients, the incidence is 0.011 %. All reported positive findings were critically reviewed, and only 11 could be considered truly unstable.

CONCLUSIONS

There is significant heterogeneity in the literature regarding the use of imaging after a negative CT. The finding rate on MRI for unstable injury is extremely low in obtunded and alert patients. Although MRI is frequently performed, its utility and cost-effectiveness needs further study.

KEY POINTS

• There were 16 unstable injuries on follow-up MRI among 5286 patients. • The positive finding rate among obtunded patients was 0.12 %. • The positive finding rate among alert, awake patients was 0.72 %. • MRI has a high false-positive rate; its utility mandates further studies. • The use and role of "confirmatory" tests shows wide variations.

Does turning trauma patients with an unstable spinal injury from the supine to a lateral position increase the risk of neurological deterioration?--A systematic review

Background

Airway protection and spinal precautions are competing concerns in the treatment of unconscious trauma patients. The placement of such patients in a lateral position may facilitate the acquisition of an adequate airway. However, trauma dogma dictates that patients should be transported in the supine position to minimize spinal movement. In this systematic review, we sought to answer the following question: Given an existing spinal injury, will changing a patient’s position from supine to lateral increase the risk of neurological deterioration?

Methods

The review protocol was published in the PROSPERO database (Reg. no. CRD42012001190). We performed literature searches in PubMed, Medline, EMBASE, the Cochrane Library, CINAHL and the British Nursing Index and included studies of traumatic spinal injury, lateral positioning and neurological deterioration. The search was updated prior to submission. Two researchers independently completed each step in the review process.

Results

We identified 1,164 publications. However, none of these publications reported mortality or neurological deterioration with lateral positioning as an outcome measure. Twelve studies used movement of the injured spine with lateral positioning as an outcome measure; eleven of these investigations were cadaver studies. All of these cadaver studies reported spinal movement during lateral positioning. The only identified human study included eighteen patients with thoracic or lumbar spinal fractures; according to the study authors, the logrolling technique did not result in any neurological deterioration among these patients.

Conclusions

We identified no clinical studies demonstrating that rotating trauma patients from the supine position to a lateral position affects mortality or causes neurological deterioration. However, in various cadaver models, this type of rotation did produce statistically significant displacements of the injured spine. The clinical significance of these cadaver-based observations remains unclear. The present evidence for harm in rotating trauma patients from the supine position to a lateral position, including the logroll maneuver, is inconclusive.
