Pediatric Cervical Spine Injury Following Blunt Trauma in Children Younger Than 3 Years: The PEDSPINE II Study.

Importance: There is variability in practice and imaging usage to diagnose cervical spine injury (CSI) following blunt trauma in pediatric patients. Objective: To develop a prediction model to guide imaging usage and to identify trends in imaging and to evaluate the PEDSPINE model. Design, Setting, and Participants: This 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. Exposure: Blunt trauma. Main Outcomes and Measures: Primary outcome was CSI. The primary and secondary objectives were predetermined. Results: The 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 Relevance: This 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.

Shark-Related Injuries in the United States: A National Trauma Data Bank Analysis.

BACKGROUND: Shark-related injuries (SRIs) are a dreaded, but rare, source of injury that have not been well described. The present study aims to examine the incidence, injuries, and outcomes of SRIs presenting to US trauma centers. STUDY DESIGN: The National Trauma Data Bank was queried from 2015 to 2018 to identify SRIs using ICD-10 e-codes W56.41XA, W56.42XA, and W56.49XA. Descriptive analyses were conducted on patient demographics, injuries, hospital course, procedures, and outcomes. RESULTS: Fifty-three patients were identified with a mechanism of injury that was shark-related. The median age was 29 years (range: 3-67) and median injury severity score was 5 (IQR: 3-10). The majority of patients (96%) were admitted to the hospital (median length of stay (LOS): 4.0 days, IQR: 3.0-8.0), 55% went directly to the operating room, and 53% required intensive care unit (ICU) admission (median ICU LOS: 4.5 days, IQR: 1.3-7.0). Extremity injuries were common: 47% suffered lower extremity injuries, 40% had upper extremity injuries, and 13% had both. The majority of patients underwent surgical procedures: 83% had soft tissue injuries requiring debridement, flap coverage, or skin grafting; 28% suffered neurovascular injuries (17% requiring nerve repair and 2% requiring arterial bypass); and 59% required orthopedic intervention. Six patients (11%) required amputation(s). All patients survived to discharge. CONCLUSION: Although an exceedingly rare source of trauma, SRIs are frequently associated with devastating injuries. Given the severity of injuries and associated procedures required, these patients warrant referral to a trauma center capable of providing comprehensive care.

The AAST prospective observational multicenter study of the initial experience with reversal of direct oral anticoagulants in trauma patients.

BACKGROUND: Drug-specific agents for the reversal of direct oral anticoagulants (DOACs) were recently approved. We hypothesized that the approval of these reversal agents would lead improved outcomes for trauma patients taking DOACs. METHODS: A multicenter, prospective (2015-2018), observational study of all adult trauma patients taking DOACs who were admitted to one of fifteen participating trauma centers was performed. The primary outcome was mortality. RESULTS: For 606 trauma patients on DOACs, those reversed were older (78 vs. 74, p = 0.007), more severely injured (ISS: 16 vs. 5, p < 0.0001), had more severe head injuries (Head AIS: 2.9 vs. 1.3, p < 0.0001), and higher mortality (11% vs. 3%, p = 0.001). Patients who received drug-specific agents (idarucizumab, andexanet alfa) had higher mortality (30% vs. 8%, p = 0.04) than those reversed with factor concentrates. However, the low usage of drug-specific reversal agents limits our ability to assess their efficacy and safety. CONCLUSIONS: DOAC reversal was not independently associated with mortality. At present, the overall usage of drug-specific reversal agents is too sparing to meaningfully assess outcomes in trauma.

Towards a more intelligent model of providing pediatric trauma care: identifying temporal variations in trauma team activations.

BACKGROUND: Trauma centers are resource-intensive environments, and pediatric-specific personnel are often limited resources. Identifying the temporal patterns of pediatric traumas can help guide resource allocation strategies to optimize patient care. METHODS: We conducted a retrospective, single-institution analysis of 575 injured patients less than 18 years old that triggered a trauma team activation (TTA). TTA volume according to time of day and day of the week was analyzed using a mixed Poisson regression model and monthly patterns were analyzed using an analysis of variance. Subset analyses were conducted for children and teenagers. RESULTS: Across all days, the 6-hour time frame between 15:00 and 21:00 had significantly more activations than average, encompassing nearly half (47.2%) of all pediatric TTAs (p=0.01). Saturdays had significantly more activations than the daily average (Saturdays: 26.0/year, Other: 14.8/year, p<0.01). A pediatric TTA was 3.6 times more likely to occur between 15:00 and 21:00 on a Saturday than any other time. Volume of activation did not significantly differ by month (p=0.880). CONCLUSION: The volume of pediatric trauma activations varies significantly according to time of day and day of the week. These findings can direct or validate resource allocation strategies such as staffing physicians, nurses, and ancillary personnel according to TTA volume. TYPE OF STUDY: Retrospective cohort study. LEVEL OF EVIDENCE: Level III.

Facial Fractures After Geriatric Ground-Level Falls Are a Marker of Functional Decline and Warrant Trauma Center Admission.

Ground-level falls (GLFs) are a frequent source of injury in the geriatric population. Facial fractures (FFs) are one subsequent injury that can occur and may be an important marker of functional decline. We conducted a retrospective analysis over a 6-year period of patients 65 years and older sustaining one or more FFs due to a GLF (n = 28). Demographics, comorbidities, FF patterns, concomitant injuries, procedures, and outcomes were analyzed. The mean age was 80.0 ± 8.2 years, 64% were male, 12 patients (43%) were on oral anticoagulants prior to injury, and mean injury severity score was 8.3 ± 7.0. Five patients (18%) had LeFort fractures (1 with LeFort I, 4 with LeFort II), and 5 (18%) had isolated mandible fractures (2 were bilateral). Nearly half of all patients suffered neurological injury (concussion: 18%, intracranial hemorrhage: 29%). Average hospital length of stay (LOS) was 4.0 ± 2.9 days. Eight patients (29%) required intensive care unit (ICU) admission with an average ICU-LOS of 2.8 ± 1.2 days. Surgical management was required in 4 patients (14%). More than half of the patients returned home (54%), 25% were discharged to a skilled nursing facility, 4% to rehabilitation, 7% to hospice, and 7% expired. Nearly one-third of patients required discharge to a higher level of care facility than their location prior to injury. GLF-induced FFs are often associated with significant injuries and serve as an indicator of functional decline. These injuries warrant trauma center admission for comprehensive evaluation and management.

Facial fractures and associated injuries in high- versus low-energy trauma: all are not created equal.

INTRODUCTION: Facial fractures (FFs) occur after high- and low-energy trauma; differences in associated injuries and outcomes have not been well articulated. OBJECTIVE: To compare the epidemiology, management, and outcomes of patients suffering FFs from high-energy and low-energy mechanisms. METHODS: We conducted a 6-year retrospective local trauma registry analysis of adults aged 18-55 years old that suffered a FF treated at the Santa Barbara Cottage Hospital. Fracture patterns, concomitant injuries, procedures, and outcomes were compared between patients that suffered a high-energy mechanism (HEM: motor vehicle crash, bicycle crash, auto versus pedestrian, falls from height > 20 feet) and those that suffered a low-energy mechanism (LEM: assault, ground-level falls) of injury. RESULTS: FFs occurred in 123 patients, 25 from an HEM and 98 from an LEM. Rates of Le Fort (HEM 12% vs. LEM 3%, P = 0.10), mandible (HEM 20% vs. LEM 38%, P = 0.11), midface (HEM 84% vs. LEM 67%, P = 0.14), and upper face (HEM 24% vs. LEM 13%, P = 0.217) fractures did not significantly differ between the HEM and LEM groups, nor did facial operative rates (HEM 28% vs. LEM 40%, P = 0.36). FFs after an HEM event were associated with increased Injury Severity Scores (HEM 16.8 vs. LEM 7.5, P <0.001), ICU admittance (HEM 60% vs. LEM 13.3%, P <0.001), intracranial hemorrhage (ICH) (HEM 52% vs. LEM 15%, P <0.001), cervical spine fractures (HEM 12% vs. LEM 0%, P = 0.008), truncal/lower extremity injuries (HEM 60% vs. LEM 6%, P <0.001), neurosurgical procedures for the management of ICH (HEM 54% vs. LEM 36%, P = 0.003), and decreased Glasgow Coma Score on arrival (HEM 11.7 vs. LEM 14.2, P <0.001). CONCLUSION: FFs after HEM events were associated with severe and multifocal injuries. FFs after LEM events were associated with ICH, concussions, and cervical spine fractures. Mechanism-based screening strategies will allow for the appropriate detection and management of injuries that occur concomitant to FFs. TYPE OF STUDY: Retrospective cohort study. LEVEL OF EVIDENCE: Level III.

Electric Scooter Injury in Southern California Trauma Centers.

BACKGROUND: Electric scooters are popular in Southern California due to their ease of use, affordability, and availability. The objective of this study was to characterize how hospital admissions and outcomes varied due to electric scooter injury among Southern California trauma centers. STUDY DESIGN: Trauma registry data from 9 urban trauma centers were queried for patients sustaining injury while operating an electric scooter from January to December 2018. Data collection included patient demographics, diagnoses, interventions, and outcomes. RESULTS: During the 1-year study period, 87 patients required trauma surgeon care due to scooter-related injury, with a mean age of 35.1 years; 71.3% were male with 20.7% and 17.2% of patients requiring ICU admission and a surgical intervention, respectively. One (1.1%) patient died. The head and face were most commonly injured, followed by the extremities. Helmet use was uncommon (71.3%). High variability in patient volume was noted, with 2 centers considered high-incidence and the remaining low-incidence. CONCLUSIONS: Injuries from electric scooter crashes are primarily to the head, face, and extremities, with approximately 1 in 5 patients requiring ICU admission and/or a surgical intervention. There is significant variation in patient volume among Southern California trauma centers that could affect the delivery of care with the abrupt introduction of this technology. Targeted public health interventions and policies might better address community use of the electric scooter.

Racial disparities and the acute management of severe blunt traumatic brain injury.

BACKGROUND: Traumatic brain injury (TBI) is a significant source of morbidity and mortality. In patients with TBI, racial disparities have been shown to exist in patient outcomes. Identifying where disparities occur along the patient continuum of care will allow for targeted interventions. This study evaluated if racial disparity exists for neuromonitoring and neurointervention rates in patients with severe TBI due to blunt injury. METHODS: The National Trauma Data Bank was used to identify patients aged 18 to 55 years old from 2007 through 2016 with a blunt injury, an initial Glasgow Coma Scale score of 3 to 8, a head Abbreviated Injury Scale score of 3 to 5, and all other anatomic Abbreviated Injury Scale scores less than 3. Coarsened exact matching (CEM) was used to balance covariates between white and non-white patients. Rates of neuromonitoring and neurosurgical interventions were compared between groups. Secondary outcomes were days spent in the intensive care unit (ICU), total hospital length of stay (LOS), and mortality. RESULTS: A total of 3692 patients with severe isolated TBI due to blunt injury were identified. After applying CEM, 1064 patients were analyzed (644 white, 420 non-white). No differences were observed between white and non-white patient groups for neuromonitoring, neurointervention, mortality, or ICU LOS. White patients had a shorter hospital LOS (8 days vs. 9 days, p<0.05) than non-white patients. DISCUSSION: For severe isolated blunt TBI, neuromonitoring, neurointervention, and mortality rates were similar for white and non-white patients. Although racial disparities in patient outcomes exist, these differences do not seem to be due to neuromonitoring and neurointervention rates for management of TBI. LEVEL OF EVIDENCE: Level III.

Reversal of warfarin anticoagulation in geriatric traumatic brain injury due to ground-level falls.

BACKGROUND: The efficacy of prothrombin complex concentrate (PCC) compared with fresh frozen plasma (FFP) for reversal of oral anticoagulants has not been investigated in geriatric patients suffering intracranial hemorrhage (ICH) due to a ground-level fall (GLF). METHODS: Patients 65 years and older who were treated at Santa Barbara Cottage Hospital between January 2011 and March 2018 with ICH after a GLF while taking warfarin were reviewed. Patients were reversed with either FFP (n=25) or PCC (n=27) and patient outcomes were compared. Separate analyses were conducted for patients who received adjuvant vitamin K administration and those who did not. RESULTS: Mortality rates, hospital length of stay, intensive care unit admission and length of stay were similar for both FFP and PCC intervention. There was no difference in radiological progression of hemorrhage within the first 24 hours of admission (FFP: 36%, PCC: 43%, p=0.365). In patients who had international normalized ratio (INR) values measured prior to intervention, 81% (17 out of 21) of the PCC group reached an INR value below 1.5 within an 8-hour period, whereas only 29% (4 out of 14) of the FFP group did (p=0.002). Vitamin K was concomitantly given to 28% of the patients receiving FFP, and 81% of those patients receiving PCC. No significant differences in outcomes were found whether adjunctive vitamin K was administered or not, in either FFP or PCC group. However, when vitamin K was not administered, the PCC group had a higher rate of INR reversal (80% vs. 10% for FFP, p=0.006). CONCLUSION: Administration of PCC is as effective in short-term outcomes as FFP in treating geriatric patients on warfarin sustaining an ICH after a GLF. INR reversal was more successful, significantly faster, and required lower infusion volumes in patients receiving PCC. LEVEL OF EVIDENCE: Level III.

Laboratory measures of coagulation among trauma patients on NOAs: results of the AAST-MIT.

BACKGROUND: Warfarin is associated with poor outcomes after trauma, an effect correlated with elevations in the international normalized ratio (INR). In contrast, the novel oral anticoagulants (NOAs) have no validated laboratory measure to quantify coagulopathy. We sought to determine if use of NOAs was associated with elevated activated partial thromboplastin time (aPTT) or INR levels among trauma patients or increased clotting times on thromboelastography (TEG). METHODS: This was a post-hoc analysis of a prospective observational study across 16 trauma centers. Patients on dabigatran, rivaroxaban, or apixaban were included. Laboratory data were collected at admission and after reversal. Admission labs were compared between medication groups. Traditional measures of coagulopathy were compared with TEG results using Spearman's rank coefficient for correlation. Labs before and after reversal were also analyzed between medication groups. RESULTS: 182 patients were enrolled between June 2013 and July 2015: 50 on dabigatran, 123 on rivaroxaban, and 34 apixaban. INR values were mildly elevated among patients on dabigatran (median 1.3, IQR 1.1-1.4) and rivaroxaban (median 1.3, IQR 1.1-1.6) compared with apixaban (median 1.1, IQR 1.0-1.2). Patients on dabigatran had slightly higher than normal aPTT values (median 35, IQR 29.8-46.3), whereas those on rivaroxaban and apixaban did not. Fifty patients had TEG results. The median values for R, alpha, MA and lysis were normal for all groups. Prothrombin time (PT) and aPTT had a high correlation in all groups (dabigatran p=0.0005, rivaroxaban p<0.0001, and apixaban p<0.0001). aPTT correlated with the R value on TEG in patients on dabigatran (p=0.0094) and rivaroxaban (p=0.0028) but not apixaban (p=0.2532). Reversal occurred in 14%, 25%, and 18% of dabigatran, rivaroxaban, and apixaban patients, respectively. Both traditional measures of coagulopathy and TEG remained within normal limits after reversal. DISCUSSION: Neither traditional measures of coagulation nor TEG were able to detect coagulopathy in patients on NOAs. LEVEL OF EVIDENCE: Level IV.

The early laparoscopic repair of a traumatic lumbar hernia: safe and successful.

Abdominal wall hernias are a rare but important consequence of blunt trauma. The optimal timing and the method of repair are not well described in the current surgical literature. Advances in laparoscopic techniques have offered new options for treatment of this problem. We describe the case of a 43-year-old man who suffered a blunt traumatic lumbar hernia. He was taken to the operating room during his initial hospitalization where a laparoscopic repair was performed with the additional implantation of prosthetic mesh. His post-operative course was uneventful. In selected cases, early operative repair may be appropriate and result in improved outcomes.

Novel oral anticoagulants and trauma: The results of a prospective American Association for the Surgery of Trauma Multi-Institutional Trial.

BACKGROUND: The number of anticoagulated trauma patients is increasing. Trauma patients on warfarin have been found to have poor outcomes, particularly after intracranial hemorrhage (ICH). However, the effect of novel oral anticoagulants (NOAs) on trauma outcomes is unknown. We hypothesized that patients on NOAs would have higher rates of ICH, ICH progression, and death compared with patients on traditional anticoagulant and antiplatelet agents. METHODS: This was a prospective observational trial across 16 trauma centers. Inclusion criteria was any trauma patient admitted on aspirin, clopidogrel, warfarin, dabigatran, rivaroxaban, or apixaban. Demographic data, admission vital signs, mechanism of injury, injury severity scores, laboratory values, and interventions were collected. Outcomes included ICH, progression of ICH, and death. RESULTS: A total of 1,847 patients were enrolled between July 2013 and June 2015. Mean age was 74.9 years (SD ± 13.8), 46% were female, 77% were non-Hispanic white. At least one comorbidity was reported in 94% of patients. Blunt trauma accounted for 99% of patients, and the median Injury Severity Score was 9 (interquartile range, 4-14). 50% of patients were on antiplatelet agents, 33% on warfarin, 10% on NOAs, and 7% on combination therapy or subcutaneous agents.Patients taking NOAs were not at higher risk for ICH on univariate (24% vs. 31%) or multivariate analysis (incidence rate ratio, 0.78; confidence interval 0.61-1.01, p = 0.05). Compared with all other agents, patients on aspirin (90%, 81 mg; 10%, 325 mg) had the highest rate (35%) and risk (incidence rate ratio, 1.27; confidence interval, 1.13-1.43; p < 0.001) of ICH. Progression of ICH occurred in 17% of patients and was not different between medication groups. Study mortality was 7% and was not significantly different between groups on univariate or multivariate analysis. CONCLUSION: Patients on NOAs were not at higher risk for ICH, ICH progression, or death. LEVEL OF EVIDENCE: Prognostic/epidemiologic study, level III.

National Outcomes after Pressure Ulcer Closure: Inspiring Surgery.

Over two million Americans receive treatment for pressure ulcers (PUs) annually, but national surgical outcomes are not well described. This study investigated rates and risk factors of postoperative complications in patients with PU. The 2011 and 2012 American College of Surgeons-National Surgical Quality Improvement Project database was queried and PU patients undergoing flap closure were identified. Descriptive statistics and multivariate regression analysis was used and reported as odds ratios (ORs) if (P < 0.05). Of 1196 patients identified with a primary diagnosis of PU, 327 (27%) underwent flap closure. Emergency interventions were performed in seven patients who were excluded from analysis. Characteristics were average age 53.3 (±17); 65 per cent male; 41 per cent with grossly contaminated or infected wounds; 29 per cent frail; and 16 per cent with an American Society of Anesthesiologists score of four or five. Myocutaneous or fasciocutaneous flaps were performed in 82 per cent of patients, local skin rearrangements in 17 per cent, and free flap in one patient. Complications were low with 1.9 per cent recurrence and 4.7 per cent reoperation rates. Higher American Society of Anesthesiologists was independently associated with mortality (odds ratio = 6.6) and steroid use correlated with flap failure (odds ratio = 15). No differences in complication profiles were identified based on technique, frailty, or contamination. Surgical closure can be considered reasonable in all patients fit for anesthesia.

Prophylactic Fresh Frozen Plasma Infusion is Ineffective in Reversing Warfarin Anticoagulation and Preventing Delayed Intracranial Hemorrhage After Falls.

BACKGROUND: Elderly patients, with considerable fall risk, are increasingly anticoagulated to prevent thromboembolic disease. We hypothesized that a policy of prophylactic fresh frozen plasma (FFP) infusion in patients having falls would reverse vitamin K antagonists (VKAs) and that reversal would decrease delayed intracranial hemorrhage (ICH). METHODS: A retrospective review of patients with trauma admitted to a level 2 community trauma center was performed from January 2010 until November 2012. Inclusion criteria were: ground level fall (GLF) with suspected head trauma, on VKA, an international normalized ratio (INR) of >1.5, and a negative head computed tomography (CT). Patients were transfused with FFP to a goal INR of <1.5 while observed. Patients were classified as reversed (REV) if the lowest INR achieved within 4 to 24 hours after initial INR was <1.5 or unreversed (NREV) if lowest INR achieved was >1.5. Chi-square and logistic regression were performed. RESULTS: A total of 194 patients met the criteria. In all, 43 (22%) patients were able to be REV, and 151 (78%) patients remained NREV. Unreversed patients were male and younger (P < .05). There was no difference in mean FFP received. Unreversed patients had a higher initial INR of 3.0 compared to REV patients (2.5; P = .018). One patient developed a delayed ICH and belonged to the REV group. CONCLUSION: The incidence of delayed hemorrhage was 0.5%. A strategy of prophylactic FFP infusion was ineffective in VKA reversal. We recommend against prophylactic infusion of FFP during a period of observation for patients on VKA with suspected head trauma and a negative initial CT.

Dabigatran Use Does Not Increase Intracranial Hemorrhage in Traumatic Geriatric Falls When Compared with Warfarin.

Patients on anticoagulation are at increased risk for intracranial hemorrhage (ICH) after trauma. This is important for geriatric trauma patients, who are increasing in number, frequently fall, and often take anticoagulants. This study sought to evaluate whether prehospital use of dabigatran, a newer anticoagulant, is associated with outcome differences in geriatric trauma patients suffering falls when compared with warfarin. The registry of a Level II community trauma center was used to identify 247 patients aged 65 and older who sustained a fall while taking prehospital dabigatran or warfarin admitted between December 2010 and March 2014. Patients on warfarin were included if their International Normalized Ratio was therapeutic (2-3). About 176 of the 247 patients were then compared using coarsened exact matching. In the matched analysis, overall population means for age, Glasgow Coma Score, and Injury Severity Score were 83.5, 14.7, and 5.1, respectively. The overall rate of ICH was 12.5 per cent, with a mortality rate of 16.1 per cent for patients who sustained an ICH. There were no observed differences in ICH, hospital length of stay, intensive care unit length of stay, or mortality between patients taking prehospital warfarin or dabigatran.

Prospective derivation of a clinical decision rule for thoracolumbar spine evaluation after blunt trauma: An American Association for the Surgery of Trauma Multi-Institutional Trials Group Study.

BACKGROUND: Unlike the cervical spine (C-spine), where National Emergency X-Radiography Utilization Study (NEXUS) and the Canadian C-spine Rules can be used, evidence-based thoracolumbar spine (TL-spine) clearance guidelines do not exist. The aim of this study was to develop a clinical decision rule for evaluating the TL-spine after injury. METHODS: Adult (≥15 years) blunt trauma patients were prospectively enrolled at 13 US trauma centers (January 2012 to January 2014). Exclusion criteria included the following: C-spine injury with neurologic deficit, preexisting paraplegia/tetraplegia, and unevaluable examination. Remaining evaluable patients underwent TL-spine imaging and were followed up to discharge. The primary end point was a clinically significant TL-spine injury requiring TL-spine orthoses or surgical stabilization. Regression techniques were used to develop a clinical decision rule. Decision rule performance in identifying clinically significant fractures was tested. RESULTS: Of 12,479 patients screened, 3,065 (24.6%) met inclusion criteria (mean [SD] age, 43.5 [19.8] years [range, 15-103 years]; male sex, 66.3%; mean [SD] Injury Severity Score [ISS], 8.8 [7.5]). The majority underwent computed tomography (93.3%), 6.3% only plain films, and 0.2% magnetic resonance imaging exclusively. TL-spine injury was identified in 499 patients (16.3%), of which 264 (8.6%) were clinically significant (29.2% surgery, 70.8% TL-spine orthosis). The majority was AO Type A1 282 (56.5%), followed by 67 (13.4%) A3, 43 (8.6%) B2, and 32 (6.4%) A4 injuries. The predictive ability of clinical examination (pain, midline tenderness, deformity, neurologic deficit), age, and mechanism was examined; positive clinical examination finding resulted in a sensitivity of 78.4% and a specificity of 72.9%. Addition of age of 60 years or older and high-risk mechanism (fall, crush, motor vehicle crash with ejection/rollover, unenclosed vehicle crash, auto vs. pedestrian) increased sensitivity to 98.9% with specificity of 29.0% for clinically significant injuries and 100.0% sensitivity and 27.3% specificity for injuries requiring surgery. CONCLUSION: Clinical examination alone is insufficient for determining the need for imaging in evaluable patients at risk of TL-spine injury. Addition of age and high-risk mechanism results in a clinical decision-making rule with a sensitivity of 98.9% for clinically significant injuries. LEVEL OF EVIDENCE: Diagnostic test, level III.

Incidence of intracranial hemorrhage and outcomes after ground-level falls in geriatric trauma patients taking preinjury anticoagulants and antiplatelet agents.

Antiplatelet and anticoagulant medication increases the risk of intracranial hemorrhage (ICH) after a fall in geriatric patients. We sought to determine whether there were differences in ICH rates and outcomes based on type of anticoagulant or antiplatelet agent after a ground-level fall (GLF). Our institutional trauma registry was used to identify patients 65 years old or older after a GLF while taking warfarin, clopidogrel, or aspirin over a 2-year period. Rates and types of ICH and patient outcomes were evaluated. Of 562 patients who met inclusion and exclusion criteria, 218 (38.8%) were on warfarin, 95 (16.9%) were on clopidogrel, and 249 (44.3%) were on aspirin. Overall ICH frequency was 15 per cent with no difference in ICH rate, type of ICH, need for craniotomy, mortality, or intensive care unit or hospital length of stay between groups. Patients with ICH were more likely to present with abnormal Glasgow Coma Score, history of hypertension, and/or loss of consciousness.

A community return-to-play mTBI clinic: results of a pilot program and survey of high school athletes.

BACKGROUND: High school athletes who sustain a mild traumatic brain injury (mTBI) or concussion are required to be removed from play until clearance by a provider. A regional pediatric trauma center offered an mTBI clinic to evaluate students for return to play (RTP). METHODS: An mTBI clinic was developed in collaboration with a high school district containing three schools. This program evaluated students suffering from sports-related head trauma, specifically football injuries. Community mTBI education was performed, a standardized RTP algorithm was developed, and a postseason survey was administered to football players. RESULTS: Twenty-eight students playing football were seen by the mTBI clinic. The average time until RTP for clinic patients was 16.9 days. Four hundred five players were surveyed. Of players responding to the survey, 40 (15%) reported sustaining an mTBI during the football season. Of those sustaining an mTBI, 9 (22.5%) did not report their symptoms. CONCLUSION: Although the mTBI rate is similar to reported rates, the unreported mTBI episodes were lower (22.5%) than previously published self-reported mTBI rates. The RTP algorithm was successful in returning athletes in 16.9 days. The algorithm and data can be utilized by other organizations in establishment of an mTBI clinic and RTP program.

What is the role of chest X-ray in the initial assessment of stable trauma patients?

BACKGROUND: The Advanced Trauma Life Support course advocates the liberal use of chest X-ray (CXR) during the initial evaluation of trauma patients. We reviewed CXR performed in the trauma resuscitation room (TR) to determine its usefulness. METHODS: A retrospective, registry-based review was conducted and included 1,000 consecutive trauma patients who underwent CXR in the TR at a Level I trauma center during a 7-month period. RESULTS: Patients receiving CXR comprised 91.5% of all patients evaluated in the TR during the study period. CXR followed by chest computed tomography (CCT) was performed in 820 (82.0%) patients. Subsequent CCT identified missed findings in 235 (35.6%) of the 660 patients with an initial negative CXR who went on to receive CCT. CXR alone was performed in 127 (26.1%) of the 487 patients who were stable, not intubated, and had a normal chest physical examination (CPE). Seven patients (5.5%) in this group had potentially significant findings but none required intervention beyond physiotherapy or antibiotics. Three hundred and sixty (73.9%) of the 487 patients who were hemodynamically stable with a normal CPE underwent both CXR and CCT. Fifty-four patients (15%) in this group had findings of significance, and two (0.6%) required intervention. One patient received bilateral chest tubes for large pre-existing pleural effusions found on CXR and CCT; another patient undergoing general anesthesia required a chest tube for a pneumothorax found only on CCT. CONCLUSION: In stable trauma patients with a normal CPE, CXR appears to be unnecessary in their initial evaluation. CXR should be relegated to a role similar to cervical spine and pelvis radiographs in the initial evaluation of hemodynamically stable trauma patients with a normal physical examination, and should be limited to use only for clear clinical indications.
