Cervical spine collar clearance in the obtunded adult blunt trauma patient: a systematic review and practice management guideline from the Eastern Association for the Surgery of Trauma.

ABSTRACT:

Background

With the use of the framework advocated by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) Working Group, our aims were to perform a systematic review and to develop evidence-based recommendations that may be used to answer the following PICO [Population, Intervention, Comparator, Outcomes] question:In the obtunded adult blunt trauma patient, should cervical collar removal be performed after a negative high-quality cervical spine (C-spine) computed tomography (CT) result alone or after a negative high-quality C-spine CT result combined with adjunct imaging, to reduce peri-clearance events, such as new neurologic change, unstable C-spine injury, stable C-spine injury, need for post-clearance imaging, false-negative CT imaging result on re-review, pressure ulcers, and time to cervical collar clearance?

Methods

Our protocol was registered with the PROSPERO international prospective register of systematic reviews on August 23, 2013 (REGISTRATION NUMBER: CRD42013005461). Eligibility criteria consisted of adult blunt trauma patients 16 years or older, who underwent C-spine CT with axial thickness of less than 3 mm and who were obtunded using any definition.Quantitative synthesis via meta-analysis was not possible because of pre-post, partial-cohort, quasi-experimental study design limitations and the consequential incomplete diagnostic accuracy data.

Results

Of five articles with a total follow-up of 1,017 included subjects, none reported new neurologic changes (paraplegia or quadriplegia) after cervical collar removal. There is a worst-case 9% (161 of 1,718 subjects in 11 studies) cumulative literature incidence of stable injuries and a 91% negative predictive value of no injury, after coupling a negative high-quality C-spine CT result with 1.5-T magnetic resonance imaging, upright x-rays, flexion-extension CT, and/or clinical follow-up. Similarly, there is a best-case 0% (0 of 1,718 subjects in 11 studies) cumulative literature incidence of unstable injuries after negative initial imaging result with a high-quality C-spine CT.

Conclusion

In obtunded adult blunt trauma patients, we conditionally recommend cervical collar removal after a negative high-quality C-spine CT scan result alone.

Project description:Background The kidney is the most frequently injured component of the genitourinary system, accounting for 5% of all trauma cases. Several guidelines by different societies address the management of urological trauma. However, unanswered questions remain regarding optimal use of angioembolization in hemodynamically stable patients, indications for operative exploration of stable retroperitoneal hematomas and renal salvage techniques in the setting of hemodynamic instability, and imaging practices for patients undergoing non-operative management. We performed a systematic review, meta-analysis, and developed evidence-based recommendations to answer these questions in both blunt and penetrating renal trauma. Methods The working group formulated four population, intervention, comparator, outcome (PICO) questions regarding the following topics: (1) angioembolization (AE) usage in hemodynamically stable patients with evidence of ongoing bleeding; (2) surgical approach to stable zone II hematomas (exploration vs. no exploration) in hemodynamically unstable patients and (3) surgical technique (nephrectomy vs. kidney preservation) for expanding zone II hematomas in hemodynamically unstable patients; (4) frequency of repeat imaging (routine or symptom based) in high-grade traumatic renal injuries. A systematic review and meta-analysis of currently available evidence was performed. RevMan 5 (Cochran Collaboration) and GRADEpro (Grade Working Group) software were used. Recommendations were voted on by working group members and concurrence was obtained for each final recommendation. Results A total of 20 articles were identified and analyzed. Two prospective studies were encountered; the majority were retrospective, single-institution studies. Not all outcomes projected by PICO questions were reported in all studies. Meta-analysis was performed for all PICO questions except PICO 3 secondary to the discrepant patient populations included in those studies. PICO 1 had the greatest number of articles included in the meta-analysis with nine studies; yet, due to differences in study design, no critical outcomes emerged; similar differences among a smaller set of articles prevented observation of critical outcomes for PICO 4. Analyses of PICOs 2 and 3 favored a non-invasive or minimally invasive approach in-line with current international practice trends. Conclusion In hemodynamically stable adult patients with clinical or radiographic evidence of ongoing bleeding, no recommendation could be made regarding the role of AE vs. observation. In hemodynamically unstable adult patients, we conditionally recommend no renal exploration vs. renal exploration in stable zone II hematomas. In hemodynamically unstable adult patients, we conditionally recommend kidney preserving techniques vs. nephrectomy in expanding zone II hematomas. No recommendation could be made for the optimal timing of repeat imaging in high grade renal injury. Level of evidence: Guideline; systematic review, level III.

Project description:ImportanceThere is variability in practice and imaging usage to diagnose cervical spine injury (CSI) following blunt trauma in pediatric patients.ObjectiveTo develop a prediction model to guide imaging usage and to identify trends in imaging and to evaluate the PEDSPINE model.Design, setting, and participantsThis cohort study included pediatric patients (<3 years years) following blunt trauma between January 2007 and July 2017. Of 22 centers in PEDSPINE, 15 centers, comprising level 1 and 2 stand-alone pediatric hospitals, level 1 and 2 pediatric hospitals within an adult hospital, and level 1 adult hospitals, were included. Patients who died prior to obtaining cervical spine imaging were excluded. Descriptive analysis was performed to describe the population, use of imaging, and injury patterns. PEDSPINE model validation was performed. A new algorithm was derived using clinical criteria and formulation of a multiclass classification problem. Analysis took place from January to October 2022.ExposureBlunt trauma.Main outcomes and measuresPrimary outcome was CSI. The primary and secondary objectives were predetermined.ResultsThe current study, PEDSPINE II, included 9389 patients, of which 128 (1.36%) had CSI, twice the rate in PEDSPINE (0.66%). The mean (SD) age was 1.3 (0.9) years; and 70 patients (54.7%) were male. Overall, 7113 children (80%) underwent cervical spine imaging, compared with 7882 (63%) in PEDSPINE. Several candidate models were fitted for the multiclass classification problem. After comparative analysis, the multinomial regression model was chosen with one-vs-rest area under the curve (AUC) of 0.903 (95% CI, 0.836-0.943) and was able to discriminate between bony and ligamentous injury. PEDSPINE and PEDSPINE II models' ability to identify CSI were compared. In predicting the presence of any injury, PEDSPINE II obtained a one-vs-rest AUC of 0.885 (95% CI, 0.804-0.934), outperforming the PEDSPINE score (AUC, 0.845; 95% CI, 0.769-0.915).Conclusion and relevanceThis study found wide clinical variability in the evaluation of pediatric trauma patients with increased use of cervical spine imaging. This has implications of increased cost, increased radiation exposure, and a potential for overdiagnosis. This prediction tool could help to decrease the use of imaging, aid in clinical decision-making, and decrease hospital resource use and cost.

Project description:Importance:Magnetic resonance imaging (MRI) continues to be performed for cervical clearance of obtunded blunt trauma, despite poor evidence regarding its utility after a normal computed tomographic (CT) finding. Objective:To evaluate the utility and cost-effectiveness of MRI vs no follow-up after a normal cervical CT finding in patients with obtunded blunt trauma. Design, Setting and Participants:This cost-effectiveness analysis evaluated an average patient aged 40 years with blunt trauma from an institutional practice. The analysis used a Markov decision model over a lifetime horizon from a societal perspective with variables from systematic reviews and meta-analyses and reimbursement rates from the Centers for Medicare & Medicaid Services, National Spinal Cord Injury Database, and other large published studies. Data were collected from the most recent literature available. Interventions:No follow-up vs MRI follow-up after a normal cervical CT finding. Results:In the base case of a 40-year-old patient, the cost of MRI follow-up was $14 185 with a health benefit of 24.02 quality-adjusted life-years (QALY); the cost of no follow-up was $1059 with a health benefit of 24.11 QALY, and thus no follow-up was the dominant strategy. Probabilistic sensitivity analysis showed no follow-up to be the better strategy in all 10 000 iterations. No follow-up was the better strategy when the negative predictive value of the initial CT was relatively high (>98%) or the risk of an injury treated with a cervical collar turning into a permanent neurologic deficit was higher than 25% or when the risk of a missed injury turning into a neurologic deficit was less than 58%. The sensitivity and specificity of MRI were varied simultaneously in a 2-way sensitivity analysis, and no follow-up remained the optimal strategy. Conclusions and Relevance:Magnetic resonance imaging had a lower health benefit and a higher cost compared with no follow-up after a normal CT finding in patients with obtunded blunt trauma to the cervical spine, a finding that does not support the use of MRI in this group of patients. The conclusion is robust in sensitivity analyses varying key variables in the model. More literature on these key variables is needed before MRI can be considered to be beneficial in the evaluation of obtunded blunt trauma.

Project description:IntroductionThe management of a patient suffering from blunt abdominal trauma (BAT) remains a challenge for the emergency physician. Within the last few years, the standard therapy for hemodynamically stable patients with BAT has transitioned to a non-operative approach. The purpose of this study is to evaluate the outcome of patients with BAT and to determine the reasons for failure of non-operative management (NOM).Materials and methodsAnalysis of 176 consecutive patients treated for BAT was conducted in a German level 1 trauma center from 2004 to 2011. Abdominal injuries were classified according to the American Association for the Surgery of Trauma (AAST). Patients included were demonstrated to have objective abdominal trauma with either free fluid on focused assessment with sonography for trauma (FAST) or computed tomography (CT), or proven organ injury.ResultsPatients, 142 of 176 (80.7%), with BAT were initially managed non-operatively, with a success rate of 90%. The rates of NOM success were higher among those with less severe injuries; 100% with Abbreviated Injury Scale (AIS) of 1. In total, 125 patients (71.0%) were managed non-operatively, and 51 (29.0%) required surgical intervention. NOM failure occurred in 9.2% of the patients, the most common reason being initially undiagnosed intestinal perforation (46.2%). Positive correlation was identified (r = 0.512; p < 0.001) between the ISS (injury severity score) and the NACA (National Advisory Committee of Aeronautics) score. The delay in operation in NOM failure was 6 h in patients with underlying hepatic or splenic rupture and 34 h with intestinal perforation. The overall mortality of 5.1% was attributed especially to old age (p = 0.016), high severity of injury (p < 0.001), and greater need for blood transfusion (p < 0.001).ConclusionNOM was successful for the vast majority of blunt abdominal trauma patients, especially those with less severe injuries. NOM failure and operative delay were most commonly due to occult hollow viscus injury (HVI), the detection of which was achieved by close clinical observation and abdominal ultrasound in conjunction with monitoring for rising markers of infection and by multidetector computed tomography (MDCT) if additionally indicated. Based on this concept, the delay in operation in patients with NOM failure was short. This study underscores the feasibility and benefit of NOM in BAT.
