Obese adolescents have higher risk for femur fracture after motor vehicle collision.

Background: Previous reports identified an association between obese adolescents (OAs) and lower extremity (LE) fractures after blunt trauma. However, the type of LE fracture remains unclear. We hypothesized that OAs presenting after motor vehicle collision (MVC) have a higher risk of severe LE fracture and will require a longer length of stay (LOS) and more support services upon discharge, compared to non-OAs. Methods: The 2017-2019 Trauma Quality Improvement Program database was queried for adolescents (12-17-years-old) presenting after MVC. The primary outcome was LE fracture. A severe fracture was defined by abbreviated injury scale ≥3. OAs were defined by a body mass index (BMI) ≥30. Results: From 22,610 MVCs, 3325 (14.7 %) included OAs. The rate of any LE fracture was higher for OAs (21.6 % vs. 18.8 %, p < 0.001). On subset analysis the only LE fracture at higher risk in OAs was a femur fracture (13 % vs. 9.1 %, p < 0.001). After adjusting for sex and age, the risk for severe LE fracture (OR 1.34, CI 1.18-1.53, p < 0.001) was higher for OAs. OAs with a femur fracture had a longer median LOS (5 vs. 4 days, p = 0.003) and were more likely discharged with additional support services including home-health or inpatient rehabilitation (30.6 % vs. 21.4 %, p < 0.001). Conclusion: OAs sustaining MVCs have increased associated risk of femur fractures. OAs are more likely to have a higher-grade LE injury, experience a longer LOS, and require additional support services upon discharge. Future research is needed to determine if early disposition planning with social work assistance can help shorten LOS.

COVID-19: A national rise in penetrating trauma cared for by a prepared trauma system.

Background: The COVID-19 pandemic negatively impacted the collective American psyche. Socioeconomic hardships including social isolation led to an increase in firearm sales. Previous regional studies demonstrated increased penetrating trauma during the pandemic but it is unclear if trauma systems were prepared for this influx of penetrating injuries. This study aimed to confirm this increased penetrating trauma trend nationally and hypothesized penetrating trauma patients treated during the pandemic had a higher risk of complications and death, compared to pre-pandemic patients. Methods: The 2017-2020 Trauma Quality Improvement Program database was divided into pre-pandemic (2017-2019) and pandemic years (2020). Bivariate analyses and a multivariable logistic regression analyses were performed controlling for age, comorbidities, injuries, and vitals on arrival. Results: From 3,525,132 patients, 936,890 (26.6 %) presented during the pandemic. The pandemic patients had a higher rate of stab-wounds (4.8 % vs. 4.5 %, p > 0.001) and gunshot wounds (5.8 % vs. 4.6 %, p < 0.001) compared to pre-pandemic patients. Among penetrating trauma patients, the rate and associated risk of in-hospital complications (5.0 % vs. 5.1 %, p = 0.38) (OR 0.98, CI 0.94-1.02, p = 0.26) was similar between pre-pandemic and pandemic cohorts but adjusted risk of mortality decreased during the pandemic (8.3 % vs. 8.3 %, p = 0.45) (OR 0.92, CI 0.89-0.96, p < 0.001). Conclusion: This national analysis confirms an increased rate of penetrating trauma during the COVID-19 pandemic, with a higher rate of gunshot injuries. However, this did not result in an increased risk of death or complications suggesting that trauma systems across the country were prepared to handle a dual pandemic of COVID and firearm violence.

iPad-Based Neurocognitive Testing (ImPACT-QT) in Acute Adult Mild Traumatic Brain Injury/Concussion: Study on Practicality and Bedside Cognitive Scores in a Level-1 Trauma Center.

BACKGROUND: There lacks rapid standardized bedside testing to screen cognitive deficits following mild traumatic brain injury (mTBI). Immediate Post-Concussion Assessment & Cognitive Testing-Quick Test (ImPACT-QT) is an abbreviated-iPad form of computerized cognitive testing. The aim of this study is to test ImPACT-QT utility in inpatient settings. We hypothesize ImPACT-QT is feasible in the acute trauma setting. METHOD: Trauma patients ages 12-70 were administered ImPACT-QT (09/2022-09/2023). Encephalopathic/medically unstable patients were excluded. Mild traumatic brain injury was defined as documented-head trauma with loss-of-consciousness <30 minutes and arrival Glasgow Coma Scale 13-15. Patients answered Likert-scale surveys. Bivariate analyses compared demographics, attention, motor speed, and memory scores between mTBI and non-TBI controls. Multivariable logistic regression assessed memory score as a predictor of mTBI diagnosis. RESULTS: Of 233 patients evaluated (36 years [IQR 23-50], 71% [166/233] female), 179 (76%) were mTBI patients. For all patients, mean test-time was 9.3 ± 2 minutes with 93% (73/76) finding the test "easy to understand." Mild traumatic brain injury patients than non-TBI control had lower memory scores (25 [IQR 7-100] vs 43 [26-100], P = .001) while attention (5 [1-23] vs 11 [1-32]) and motor score (14 [3-28] vs 13 [4-32]) showed no significant differences. Multivariable-regression (adjustment: age, sex, race, education level, ISS, and time to test) demonstrated memory score predicted mTBI positive status (OR .96, CI .94-.98, P = .004). DISCUSSION: Immediate Post-Concussion Assessment & Cognitive Testing-Quick Test is feasible in trauma patients. Preliminary findings suggest acute mTBIs have lower memory but not attention/motor scores vs non-TBI trauma controls.

Immediate Operative Trauma Assessment Score: A Simple and Reliable Predictor of Mortality in Trauma Patients Undergoing Urgent/Emergent Surgery.

Objective: Many current trauma mortality prediction tools are either too intricate or rely on data not readily available during a trauma patient's initial evaluation. Moreover, none are tailored to those necessitating urgent or emergent surgery. Our objective was to design a practical, user-friendly scoring tool using immediately available variables, and then compare its efficacy to the widely-known Revised Trauma Score (RTS). Methods: The adult 2017-2021 Trauma Quality Improvement Program (TQIP) database was queried to identify patients ≥18 years old undergoing any urgent/emergent operation (direct from Emergency Department to operating room). Patients were divided into derivation and validation groups. A three-step methodology was used. First, multiple logistic regression models were created to determine risk of death using only variables available upon arrival. Second, the weighted average and relative impact of each independent predictor was used to derive an easily calculated Immediate Operative Trauma Assessment Score (IOTAS). We then validated IOTAS using AUROC and compared it to RTS. Results: From 249 208 patients in the derivation-set, 14 635 (5.9%) died. Age ≥65, Glasgow Coma Scale score <9, hypotension (SBP <90 mmHg), and tachycardia (>120/min) on arrival were identified as independent predictors for mortality. Using these, the IOTAS was structured, offering scores between 0-8. The AUROC for this was .88. A clear escalation in mortality was observed across scores: from 4.4% at score 1 to 60.5% at score 8. For the validation set (250 182 patients; mortality rate 5.8%), the AUROC remained consistent at .87, surpassing RTS's AUROC of .83. Conclusion: IOTAS is a novel, accurate, and now validated tool that is intuitive and efficient in predicting mortality for trauma patients requiring urgent or emergent surgeries. It outperforms RTS, and thereby may help guide clinicians when determining the best course of action in patient management as well as counseling patients and their families.

Blunt Abdominal Trauma in Pregnancy: Higher Rates of Severe Abdominal Injuries.

BACKGROUND: Previous studies suggest increased abdominal girth in obese individuals provides a "cushion effect," against severe abdominal trauma. In comparison, the unique anatomic/physiological condition of pregnancy, such as the upward displacement of organs by an expanding uterus, may decrease risk of abdominal injury. However, increased overall blood volume and vascularity of organs during pregnancy raise concerns for increased bleeding and potentially more severe injuries. Therefore, this study aimed to elucidate whether the "cushion effect" observed in obese patients extends to pregnant trauma patients (PTPs). We hypothesized a lower risk of blunt solid organ injury (BSOI) (liver, spleen, and kidney) in pregnant vs non-pregnant blunt trauma patients. METHODS: The 2020-2021 Trauma Quality Improvement Program was queried for all female blunt trauma patients (age<50 years) involved in motor vehicle collisions (MVCs). We compared pregnant vs non-pregnant patients. The primary outcomes were incidence of BSOI, and severity of abdominal trauma defined by abbreviated injury scale (AIS). RESULTS: From 94,831 female patients, 2598 (2.7%) were pregnant. When compared to non-pregnant patients, PTPs had lower rates of liver (5.5% vs 7.6%, P < .001) and kidney (1.8% vs 2.6%, P = .013) injury. However, PTPs had higher rates of serious (13.4% vs 9.0%, P < .001) and severe abdominal injury (7.5% vs 4.3%, P < .001). DISCUSSION: BSOI occurred at a lower rate in PTPs compared to non-PTPs; however, contrary to the "cushion effect" observed in obese populations, pregnant women had a higher rate of severe abdominal injuries. These data support comprehensive evaluations for PTPs presenting after a MVC. LEVEL OF EVIDENCE: IV (therapeutic).

Similar rate of venous thromboembolism (VTE) and failure of non-operative management for early versus delayed VTE chemoprophylaxis in adolescent blunt solid organ injuries: a propensity-matched analysis.

BACKGROUND: Early initiation of venous thromboembolism (VTE) chemoprophylaxis in adults with blunt solid organ injury (BSOI) has been demonstrated to be safe but this is controversial in adolescents. We hypothesized that adolescent patients with BSOI undergoing non-operative management (NOM) and receiving early VTE chemoprophylaxis (eVTEP) (≤ 48 h) have a decreased rate of VTE and similar rate of failure of NOM, compared to similarly matched adolescents receiving delayed VTE chemoprophylaxis (dVTEP) (> 48 h). METHODS: The 2017-2019 Trauma Quality Improvement Program database was queried for adolescents (12-17 years of age) with BSOI (liver, kidney, and/or spleen) undergoing NOM. We compared eVTEP versus dVTEP using a 1:1 propensity score model, matching for age, comorbidities, BSOI grade, injury severity score, hypotension on arrival, and need for transfusions. We performed subset analyses in patients with isolated spleen, kidney, and liver injury. RESULTS: From 1022 cases, 417 (40.8%) adolescents received eVTEP. After matching, there was no difference in matched variables (all p > 0.05). Both groups had a similar rate of VTE (dVTEP 0.6% vs. eVTEP 1.7%, p = 0.16), mortality (dVTEP 0.3% vs. eVTEP 0%, p = 0.32), and failure of NOM (eVTEP 6.7% vs. dVTEP 7.3%, p = 0.77). These findings remained true in all subset analyses of isolated solid organ injury (all p > 0.05). CONCLUSIONS: The rate of VTE with adolescent BSOI is exceedingly rare. Early VTE chemoprophylaxis in adolescent BSOI does not increase the rate of failing NOM. However, unlike adult trauma patients, adolescent patients with BSOI receiving eVTEP had a similar rate of VTE and death, compared to adolescents receiving dVTEP.

Combined Arterial and Venous Lower Extremity Injury.

This case-control study assesses the need for prophylactic fasciotomy and delayed fasciotomy in combined arterial and venous injury compared with those with isolated artery or vein injury.

Development of a novel scoring tool to predict the need for early cricothyroidotomy in trauma patients.

Background: The lack of a widely-used tool for predicting early cricothyroidotomy in trauma patients prompted us to develop the Cricothyroidotomy After Trauma (CAT) score. We aimed to predict the need for cricothyroidotomy within one hour of trauma patient arrival. Methods: Derivation and validation datasets were obtained from the Trauma Quality Improvement Program (TQIP) database. Logistic modeling identified predictors, and weighted averages were used to create the CAT score. The score's performance was assessed using AUROC. Results: Among 1,373,823 derivation patients, <1 % (n = 339) underwent cricothyroidotomy within one hour. The CAT score, comprising nine predictors, achieved an AUROC of 0.88. Severe neck injury and gunshot wound were the strongest predictors. Cricothyroidotomy rates increased from 0.4 % to 9.3 % at scores of 5 and 8, respectively. In the validation set, the CAT tool yielded an AUROC of 0.9. Conclusion: The CAT score is a validated tool for predicting the need for early cricothyroidotomy in trauma patients. Further research is necessary to enhance its utility and assess its value in trauma care.

Scoring Tool to Predict Need for Early Video-Assisted Thoracoscopic Surgery (VATS) After Pediatric Trauma.

BACKGROUND: No widely used stratification tool exists to predict which pediatric trauma patients may require a video-assisted thoracoscopic surgery (VATS). We sought to develop a novel VATS-In-Pediatrics (VIP) score to predict the need for early VATS (within 72 h of admission) for pediatric trauma patients. METHODS: The pediatric 2017-2020 Trauma Quality Improvement Program database was used and divided into two sets (derivation set using 2017-2019 data and validation set using 2020 data). First, multiple logistic regression models were created to determine the risk of early VATS for patients ≤ 17 years old. Second, the weighted average and relative impact of each independent predictor were used to derive a VIP score. We then validated the score using the area under the receiver operating characteristic (AROC) curve. RESULTS: From 218,628 patients in the derivation set, 2183 (1.0%) underwent early VATS. A total of 8 independent predictors of VATS were identified, and the VIP score was derived with scores ranging from 0 to 9. The AROC for this was 0.91. The VATS rate increased steadily from 12.5 to 32% then 60.5% at scores of 3, 4, and 6, respectively. In the validation set, from 70,316 patients, 887 (1.3%) underwent VATS, and the AROC was 0.91. CONCLUSIONS: VIP is a novel and validated scoring tool to predict the need for early VATS in pediatric trauma. This tool can potentially help hospital systems prepare for pediatric patients at high risk for requiring VATS during their first 72 h of admission. Future prospective research is needed to evaluate VIP as a tool that can improve clinical outcomes.

Diagnostic Peritoneal Aspiration or Lavage in Stratified Groups of Hypotensive Blunt Trauma Patients.

BACKGROUND: Some reports suggest Diagnostic peritoneal aspiration (DPA) or lavage (DPL) may better select which hypotensive blunt trauma patients (BTPs) require operation, compared to ultrasonography. However, whether both moderately hypotensive (systolic blood pressure [SBP] < 90 mmHg) and severely hypotensive (SBP < 70 mmHg) patients benefit from DPA/DPL is unclear. We hypothesized DPA/DPL used within the first hour increases risk of death for severely vs moderately hypotensive BTPs. METHODS: The 2017-2019 Trauma Quality Improvement Program database was queried for BTPs ≥ 18 years old with hypotension upon arrival. We compared moderately and severely hypotensive groups. A multivariable logistic regression analysis was performed controlling for age, comorbidities, emergent operation, blood transfusions, and injury profile. RESULTS: From 134 hypotensive patients undergoing DPA/DPL, 66 (49.3%) had severe hypotension. Patients in both groups underwent an emergent operation (43.9% vs 58.8%, P = .09) in a similar amount of time (median, 42-min vs 54-min, P = .11). Compared to the moderately hypotensive group, severely hypotensive patients had a higher rate and associated risk of death (84.8% vs 50.0%, P < .001) (OR 5.40, CI 2.07-14.11, P < .001). The strongest independent risk factor for death was age ≥ 65 (OR 24.81, CI 4.06-151.62, P < .001). DISCUSSION: Among all BTPs undergoing DPA/DPL within the first hour of arrival, an over 5-fold increased risk of death for patients with severe hypotension was demonstrated. As such, DPA/DPL within this group should be used with caution, particularly for older patients, as they may be better served by immediate surgeries. Future prospective research is needed to confirm these findings and elucidate the ideal DPA/DPL population in the modern era of ultrasonography.

Laparoscopy in the Evaluation of Blunt Abdominal Injury in Level-I and II Pediatric Trauma Centers.

INTRODUCTION: An American College of Surgeons (ACS) Level-I (L-I) pediatric trauma center demonstrated successful laparoscopy without conversion to laparotomy in ∼65% of trauma cases. Prior reports have demonstrated differences in outcomes based on ACS level of trauma center. We sought to compare laparoscopy use for blunt abdominal trauma at L-I compared to Level-II (L-II) centers. METHODS: The Pediatric Trauma Quality Improvement Program was queried (2014-2016) for patients ≤16 years old who underwent any abdominal surgery. Bivariate analyses comparing patients undergoing abdominal surgery at ACS L-I and L-II centers were performed. RESULTS: 970 patients underwent abdominal surgery with 14% using laparoscopy. Level-I centers had an increased rate of laparoscopy (15.6% vs 9.7%, P = .019); however they had a lower mean Injury Severity Score (16.2 vs 18.5, P = .002) compared to L-II centers. Level-I and L-II centers had similar length of stay ventilator days, and SSIs (all P > .05). CONCLUSION: While use of laparoscopy for pediatric trauma remains low, there was increased use at L-I compared to L-II centers with no difference in LOS or SSIs. Future studies are needed to elucidate which pediatric trauma patients benefit from laparoscopic surgery.

Antibiotic administration within 1 hour for open lower extremity fractures is not associated with decreased risk of infection.

BACKGROUND: Open fractures have a high risk of infection with limited data correlating timing of prophylactic antibiotic administration and rate of subsequent infection. The Trauma Quality Improvement Program has established a standard of antibiotic administration within 1 hour of arrival, but there is a lack of adequately powered studies validating this quality metric. We hypothesize that open femur and/or tibia fracture patients undergoing orthopedic surgery have a decreased risk of infectious complications (osteomyelitis, deep and superficial surgical site infection) if antibiotics are administered within 1 hour of presentation compared with administration after 1 hour. METHODS: The 2019 Trauma Quality Improvement Program was queried for adults with isolated (Abbreviated Injury Scale <1 for the head/face/spine/chest/abdomen/upper extremity) open femur and/or tibia fractures undergoing orthopedic surgery. Transfer patients were excluded. Patients receiving early antibiotics (EA) within 1 hour were compared with patients receiving delayed antibiotics (DA) greater than 1 hour from arrival. RESULTS: Of 3,367 patients identified, 2,400 (70.4%) received EA. Patients receiving EA had a higher rate of infections compared with DA (1.1% vs. 0.2%, p = 0.011). After adjusting for age, comorbidities, injury severity, nerve/vascular trauma to the lower extremity, washout of the femur/tibia performed in <6 hours, blood transfusion, and admission vitals, patients in the EA group had a similar associated risk of surgical site infection/osteomyelitis compared with the DA cohort ( p = 0.087). These results remained in subset analyses of patients with only femur, only tibia, and combined femur/tibia open fractures (all p > 0.05). CONCLUSION: In this large national analysis, approximately 70% of isolated open femur or tibia fracture patients undergoing surgery received antibiotics within 1 hour. After adjusting for known risk factors of infection, there was no association between timing of antibiotic administration and infection. Reconsideration of the quality metric of antibiotic administration within 1 hour for open fractures appears warranted. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

No Difference in Mortality and Outcomes After Addition of a Nearby Pediatric Trauma Center.

OBJECTIVES: Previous studies demonstrate that higher volume pediatric trauma centers (PTCs) offer improved outcomes. This study evaluated pediatric trauma volume and outcomes at an existing level I (L-I) adult and level II (L-II) PTC after the addition of a new children's hospital L-II PTC within a 2-mile radius, hypothesizing no difference in mortality and complications. METHODS: A retrospective review of patients aged 14 years or younger presenting to a single adult L-I and L-II PTC was performed. Patients from 2015-2016 (PRE) were compared with patients from 2018-2019 (POST) for mortality and complications using bivariate analyses. RESULTS: Compared with the PRE cohort, there were less patients in the POST cohort (277 vs 373). Patients in the POST cohort had higher rates of insurance coverage (91.3% vs 78.8%, P < 0.001), self-transportation (7.2% vs 2.7%, P < 0.01), and hospital admission (72.6% and 46.1%, P < 0.001). There was no difference in all complications and mortality (all P > 0.05) between the 2 cohorts. CONCLUSIONS: After opening a second L-II PTC within a 2-mile radius, there was an increase in the rate of admissions and self-transportation to the preexisting L-II PTC. Despite a nearly 26% decrease in pediatric trauma volume, there was no difference in length of stay, hospital complications, or mortality.

Facial Fractures Have Similar Outcomes When Managed by Either Otolaryngology or Plastic Surgery: Encounters From a Single Level I Trauma Center.

Study Design: Retrospective cohort. Objective: Traumatic facial fractures (FFs) often require specialty consultation with Plastic Surgery (PS) or Otolaryngology (ENT); however, referral patterns are often non-standardized and institution specific. Therefore, we sought to compare management patterns and outcomes between PS and ENT, hypothesizing no difference in operative rates, complications, or mortality. Methods: We performed a retrospective analysis of patients with FFs at a single Level I trauma center from 2014 to 2017. Patients were compared by consulting service: PS vs. ENT. Chi-square and Mann-Whitney-U tests were performed. Results: Of the 755 patients with FFs, 378 were consulted by PS and 377 by ENT. There was no difference in demographic data (P > 0.05). Patients managed by ENT received a longer mean course of antibiotics (9.4 vs 7.0 days, P = 0.008) and had a lower rate of open reduction internal fixation (ORIF) (9.8% vs. 15.3%, P = 0.017), compared to PS patients. No difference was observed in overall operative rate (15.1% vs. 19.8%), use of computed tomography (CT) imaging (99% vs. 99%), time to surgery (65 vs. 55 hours, P = 0.198), length of stay (LOS) (4 vs. 4 days), 30-day complication rate (10.6% vs. 7.1%), or mortality (4.5% vs. 2.6%) (all P > 0.05). Conclusion: Our study demonstrated similar baseline characteristics, operative rates, complications, and mortality between FFs patients who had consultation by ENT and PS. This supports the practice of allowing both ENT and PS to care for trauma FFs patients, as there appears to be similar standardized care and outcomes. Future studies are needed to evaluate the generalizability of our findings.

Comparison of Same and Different Level Height Falls on Subsequent Midline Shift in Pediatric Traumatic Brain Injury.

OBJECTIVES: Up to 44% of pediatric traumatic brain injury occurs as a result of a fall. We hypothesized that a fall from height is associated with higher risk for subsequent midline shift in pediatric traumatic brain injury compared with a fall from same level. METHODS: The Pediatric Trauma Quality Improvement Program 2016 was queried for kids younger than 16 years with an injury in the abbreviated injury scale for the head after a fall. Patients with midline shift were identified. A logistic regression model was used for analysis. RESULTS: The risk of a midline shift was lower in those with a fall from a height (odds ratio, 0.64; 95% confidence interval, 0.46-0.91, P = 0.01). In kids older than 4 years, there was no association between the level of height of the fall and subsequent midline shift (P = 0.62). The risk for midline shift in kids younger than 4 years after a fall from same level was lower (odds ratio, 0.40; 95% confidence interval, 0.24-0.67; P = 0.001). CONCLUSIONS: In kids with traumatic brain injury, trauma activations due to falls from the same level are associated with a 2.5-fold higher risk of subsequent midline shift, compared with falling from height.

Blunt Trauma Mortality: Does Trauma Center Level Matter?

INTRODUCTION: Trauma centers have improved outcomes compared to nontrauma centers when caring for injured patients. A multicenter report found blunt trauma patients treated at American College of Surgeons' Level I trauma centers have improved survival compared to Level II centers. In a subsequent multicenter study, Level II centers had improved survival in all trauma patients. We sought to provide a more granular analysis by stratifying blunt mechanisms-to determine if there was a difference in mortality between Level I and Level II centers. METHODS: The Trauma Quality Improvement Program (2010-2016) was queried for patients presenting to an American College of Surgeons' Level I or II trauma center after blunt trauma. A multivariable logistic regression analysis was performed controlling for comorbidities and Trauma and Injury Severity Score. RESULTS: From 734,473 patients with blunt trauma, 507,715 (69.1%) were treated at a Level I center and 226,758 (30.9%) at a Level II center. The Level I cohort was younger (median age, 53 versus 58, P = 0.01), with a higher median injury severity score (13 versus 10, P < 0.001) and with more patients presenting after a motor vehicle accident (MVA) (27.9% versus 22.4%, P < 0.001) and lower rates of falls (46.6% versus 54.5%, P < 0.001). After adjusting for covariates, there was no difference in mortality between Level I and Level II centers (P > 0.05). When stratifying by mechanisms, Level I centers had a decreased associated mortality for MVA (odds ratio = 0.94, CI: 0.88-0.99, P = 0.04) and bicycle accidents (odds ratio = 0.77, CI: 0.74-0.03, P = 0.01) but no difference in falls or pedestrians struck (P > 0.05). CONCLUSIONS: Overall, blunt trauma patients presenting to a Level I center have no difference in mortality compared to a Level II center. However, when stratified by mechanism, those involved in MVA or bicycle accidents have a decreased associated risk of mortality. Future prospective studies examining variations in practice to account for these differences are warranted.

Helmets Protect Pediatric Bicyclists From Head Injury and Do Not Increase Risk of Cervical Spine Injury.

OBJECTIVES: Only 21 states have mandatory helmet laws for pediatric bicyclists. This study sought to determine the incidence of helmeted riders among pediatric bicyclists involved in a collision and hypothesized the risk of a serious head and cervical spine injuries to be higher in nonhelmeted bicyclists (NHBs) compared with helmeted bicyclists (HBs). METHODS: The Pediatric Trauma Quality Improvement Program (2014-2016) was queried for pediatric (age <16 years) bicyclists involved in a collision. Helmeted bicyclists were compared with NHBs. A serious injury was defined by an abbreviated injury scale grade of greater than 2. RESULTS: From 3693 bicyclists, 3039 (82.3%) were NHBs. Compared with HBs, NHBs were more often Black (21.6% vs 3.8%, P < 0.001), Hispanic (17.5% vs 9.3%, P < 0.001), without insurance (4.6% vs 2.4%, P = 0.012), and had a higher rate of a serious head injury (24.6% vs 9.3%, P < 0.001). Both groups had similar rates of complications and mortality (P > 0.05). The associated risk of a serious head (odds ratio = 3.17, P < 0.001) and spine injury (odds ratio = 0.41, P = 0.012) were higher and lower respectively in NHBs. Associated risks for cervical spine fracture or cord injury were similar (P > 0.05). CONCLUSIONS: Pediatric bicyclists involved in a collision infrequently wear helmets, and NHBs was associated with higher risks of serious head injury. However, the associated risk of serious spine injury among NHBs was lower. The associated risks for cervical spine fracture or cervical cord injuries were similar. Nonhelmeted bicyclists were more likely to lack insurance and to be Black or Hispanic. Targeted outreach programs may help decrease the risk of injury, especially in at-risk demographics.

Race, Age, and Lack of Insurance Increase Risk of Suicide Attempt in Trauma Patients.

OBJECTIVE: The overall rate of suicide between 1999 and 2017 increased by 33% in the United States. We sought to examine suicide attempts in the trauma patient population, hypothesizing that in adult trauma patients race and lack of insurance status would be predictors of suicide attempt. METHOD: The Trauma Quality Improvement Program (2010-2016) was queried for trauma patients ≥18 years old. The primary outcome was suicide attempt. A multivariable logistic regression model was performed including covariates that influence risk of suicide attempt. RESULTS: From 1,403,466 adult trauma admissions, 16,263 (1.2%) patients attempted suicide. Death after suicide attempt occurred in 30.2% of patients. Independent predictors of suicide attempt were age < 40 years old (odds ratio [OR] = 1.46, 95% confidence interval [CI] [1.41, 1.51], p < .001) and no insurance (OR = 1.92, 95% CI [1.85, 2.00], p < .001). Black (vs. White) race was associated with decreased risk of suicide attempt (OR = 0.63, 95% CI [0.60, 0.67], p < .001). Hispanic (versus non-Hispanic) patients demonstrated lower associated risk of suicide attempt by gun (OR = 0.50, 95% CI [0.45, 0.54], p < .001), while Asian (vs. White) patients exhibited higher risk of suicide attempt overall (OR = 1.25, 95% CI [1.12, 1.39], p < .001) and more specifically by knife (OR = 2.55, 95% CI [2.16, 3.00], p < .001). CONCLUSIONS: Age younger than 40 years and lack of insurance were associated with higher risk of suicide attempt in adult trauma patients. Asian race was associated with the highest risk of suicide, with >2.5 times increased risk of attempt by knife. Awareness of these demographic-specific risk factors for suicide attempt, and in particular violent mechanisms of suicide attempt, is critical to implementation of effective suicide prevention efforts.HighlightsAge younger than 40 and no insurance were associated with risk of suicide attempt.Black (vs. White) race was associated with decreased risk of suicide attempt.Asian race was associated with an increased risk of suicide attempt with a knife.

Comparison of surgical fixation and non-operative management in patients with traumatic sternum fracture.

PURPOSE: The incidence of sternal fractures in blunt trauma patients lies between 3 and 7%. The role, timing and indications for surgical management are not well delineated and remain controversial for patients undergoing surgical stabilization of sternum fracture (SSSF). We sought to identify the national rate of SSSF in patients with a sternum fracture hypothesizing patients undergoing SSSF will have a decreased rate of mortality and complications. METHODS: The Trauma Quality Improvement Program (2015-2016) was queried for patients with sternum fracture. Propensity scores were calculated to match patients undergoing SSSF to patients managed non-operatively in a 1:2 ratio using demographic data. RESULTS: From 9460 patients with a sternum fracture, 114 (1.2%) underwent SSSF. After propensity-matching, 112 SSSF patients were compared to 224 patients undergoing non-operative management (NOM). There were no differences in matched characteristics (all p > 0.05). Compared to patients undergoing NOM, patients undergoing SSSF had an increased median length of stay (LOS) (16 vs. 7 days, p < 0.001), ICU LOS (9.5 vs. 5.5 days, p = 0.016) and ventilator days (8 vs. 5, p = 0.035). The SSSF group had a similar rate of ARDS (2.7% vs. 2.2%, p = 0.80), pneumonia (1.8% vs. 0.9%, p = 0.48) and unplanned intubation (8.9% vs. 5.8%, p = 0.29) but a lower mortality rate (2.7% vs. 11.2%, p = 0.008). CONCLUSION: Just over 1% of patients with sternum fracture underwent SSSF in a national analysis. Patients undergoing SSSF had an increased LOS and similar rate of all measured pulmonary complications, however a lower mortality rate compared to patients managed non-operatively.
