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.

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.

Blunt Trauma Massive Transfusion (B-MaT) Score: A Novel Scoring Tool.

BACKGROUND: Multiple tools predicting massive transfusion (MT) in trauma have been developed but utilize variables that are not immediately available. Additionally, they only differentiate blunt from penetrating trauma and do not account for the large range of blunt mechanisms and their difference in force. We aimed to develop a Blunt trauma Massive Transfusion (B-MaT) score that accounts for high-risk blunt mechanisms and predicts MT needs in blunt trauma patients (BTPs) prior to arrival. MATERIALS AND METHODS: The adult 2017 Trauma Quality Improvement Program database was used to identify BTPs who were divided into 2 sets at random (derivation/validation). First, multiple logistic regression models were created to determine risk factors of MT (≥6 units of PRBCs within 4-hours or ≥10 units within 24-hours). Next, the weighted average and relative impact of each independent predictor was used to derive a B-MaT score. Finally, the area under the receiver-operating curve (AROC) was calculated. RESULTS: Of 172,423 patients in the derivation-set, 1,160 (0.7%) required MT. Heart rate ≥ 120bpm, systolic blood pressure ≤ 90mmHg, and high-risk blunt mechanisms were identified as independent predictors for MT. B-MaT scores were derived ranging from 0 -9, with scores of 6, 7, and 9 yielding a MT rate of 11.7%, 19.4%, and 32.4%, respectively. The AROC was 0.86. The validation-set had an AROC of 0.85. CONCLUSIONS: B-MaT is a novel scoring tool that predicts need for MT in BTPs and can be calculated prior to arrival. B-MaT warrants prospective validation to confirm its accuracy and assess its ability to improve patient outcomes and blood product allocation.

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.

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.

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.

Association of Risk of Mortality in Pediatric Patients Transferred From Scene by Helicopter With Major But Not Minor Injuries.

OBJECTIVES: Helicopter emergency medical services (HEMS) are used for 16% of pediatric trauma. National HEMS guidelines advised that triage criteria be standardized for pediatric patients. A national report found pediatric HEMS associated with decreased mortality compared with ground emergency medical services (GEMS) but did not control for transport time. We hypothesized that the rate of HEMS has decreased nationally and the mortality risk for HEMS to be similar when adjusting for transport time compared with GEMS. METHODS: The Pediatric Trauma Quality Improvement Program (2014-2016) was queried for patients younger than 16 years transported by HEMS or GEMS. A multivariable logistic regression was used. RESULTS: From 25,647 patients, 4527 (17.7%) underwent HEMS. The rate of HEMS from scene decreased from 21.2% in 2014 to 18.2% in 2016. The rate of HEMS for minor trauma (Injury Severity Score <15) decreased from 14.9% in 2014 to 13.5% in 2016 and major trauma (Injury Severity Score > 15) from 38.4% in 2014 to 35.9% in 2016. After controlling for predictors of mortality and transport time, HEMS was associated with decreased risk of mortality for only those with major injuries transferred from scene (odds ratio, 0.48; 95% confidence interval, 0.26-0.88; P = 0.01) compared with GEMS. CONCLUSIONS: The rate of HEMS in pediatric trauma has decreased. However, there is room for improvement as 14% of those with minor trauma are transported by HEMS. Given the similar risk of mortality compared with GEMS, further development of guidelines that avoid the unnecessary use of HEMS appears warranted. However, utilization of HEMS for transport of pediatric major trauma should continue.

A Dual Pandemic: The Influence of Coronavirus Disease 2019 on Trends and Types of Firearm Violence in California, Ohio, and the United States.

BACKGROUND: This study sought to determine the impact of coronavirus disease 2019 stay-at-home (SAH) and reopening orders on trends and types of firearm violence in California, Ohio, and the United States, hypothesizing increased firearm violence after SAH. MATERIALS AND METHODS: Retrospective data (January 1, 2018, to July 31, 2020) on firearm incidents/injuries/deaths and types of firearm violence were obtained from the Gun Violence Archive. The periods for SAH and reopening for the US were based on dates for California. Ohio dates were based on Ohio's timeline. Mann-Whitney U analyses compared trends and types of daily firearm violence per 100,000 legal firearm owners across 2018-2020 periods. RESULTS: In California, SAH and reopening orders had no effect on firearm violence in 2020 compared with 2018 and 2019 periods, respectively. In Ohio, daily median firearm deaths increased during 2020 SAH compared with 2018 and 2019 and firearm incidents and injuries increased during 2020 reopening compared with 2018, 2019 and 2020 SAH. In the United States, during 2020, SAH firearm deaths increased compared with historical controls and firearm incidents, deaths and injuries increased during 2020 reopening compared with 2018, 2019 and 2020 SAH (all P < 0.05). Nationally, when compared with 2018 and 2019, 2020 SAH had increased accidental shootings deaths with a decrease in defensive use, home invasion, and drug-involved incidents. CONCLUSIONS: During 2020 SAH, the rates of firearm violence increased in Ohio and the United States but remained unchanged in California. Nationally, firearm incidents, deaths and injuries also increased during 2020 reopening versus historical and 2020 SAH data. This suggests a secondary "pandemic" as well as a "reopening phenomenon," with increased firearm violence not resulting from self-defense.

Isolated Thoracic Injury Patients With Rib Fractures Undergoing Rib Fixation Have Improved Mortality.

BACKGROUND: Despite a lack of consensus recommendations for surgical stabilization of rib fractures (SSRF), SSRF has increased over the past decade. Outcomes of patients with isolated thoracic injuries undergoing SSRF are unknown. We hypothesized adult trauma patients with isolated thoracic injuries and rib fractures undergoing SSRF would have a decreased risk of mortality and in-hospital respiratory complications compared with those not undergoing SSRF. MATERIALS AND METHODS: The Trauma Quality Improvement Program (2010-2016) was queried for patients presenting with a rib fracture. Patients who died in the emergency department or within 24-h, as well as those with a grade>1 for abbreviated injury scale of the head, face, neck, spine, abdomen, and extremities, were excluded. A multivariable logistic regression analysis was performed. RESULTS: From 60,000 patients with isolated thoracic injuries and rib fractures, 688 (1.1%) underwent SSRF. Compared with patients without SSRF, those undergoing SSRF had a similar median age (P = 0.83) and higher injury severity score (P < 0.001). Patients undergoing SSRF had a longer length of stay (P < 0.001), higher rate of acute respiratory distress syndrome (P < 0.001), unplanned intubation (P < 0.001), and pneumonia (P < 0.001) but lower rate of mortality (0.9% versus 1.7%, P = 0.084). After adjusting for confounding variables, patients undergoing SSRF had a decreased associated risk of mortality (OR 0.40, P = 0.036) compared with those not undergoing SSRF. CONCLUSIONS: The risk of mortality in trauma patients with isolated thoracic injuries and rib fractures is lower when undergoing SSRF despite being associated with a higher rate of respiratory complications during their increased length of stay.

University Teaching Trauma Centers: Decreased Mortality but Increased Complications.

BACKGROUND: Teaching hospitals are often regarded as excellent institutions with significant resources and prominent academic faculty. However, the involvement of trainees may contribute to higher rates of complications. Conflicting reports exist regarding outcomes between teaching and nonteaching hospitals, and the difference among trauma centers is unknown. We hypothesized that university teaching trauma centers (UTTCs) and nonteaching trauma centers (NTTCs) would have a similar risk of complications and mortality. METHODS: We queried the Trauma Quality Improvement Program (2010-2016) for adults treated at UTTCs or NTTCs. A multivariable logistic regression analysis was performed to evaluate the risk of mortality and in-hospital complications, such as respiratory complications (RCs), venous thromboembolisms (VTEs), and infectious complications (ICs). RESULTS: From 895,896 patients, 765,802 (85%) were treated at UTTCs and 130,094 (15%) at NTTCs. After adjusting for covariates, UTTCs were associated with an increased risk of RCs (odds ratio (OR) 1.33, confidence interval (CI) 1.28-1.37, P < 0.001), VTEs (OR 1.17, CI 1.12-1.23, P < 0.001), and ICs (OR 1.56, CI 1.49-1.64, P < 0.001). However, UTTCs were associated with decreased mortality (OR 0.96, CI 0.93-0.99, P = 0.008) compared with NTTCs. CONCLUSIONS: Our study demonstrates increased associated risks of RCs, VTEs, and ICs, yet a decreased associated risk of in-hospital mortality for UTTCs when compared with NTTCs. Future studies are needed to identify the underlying causative factors behind these differences.

Evolving Utility of Endovascular Treatment of Juxtarenal, Pararenal, and Suprarenal Abdominal Aortic Aneurysms Associated With Increased Risk of Mortality Over Time.

BACKGROUND: Continued advances in endovascular technologies are resulting in fewer open abdominal aortic aneurysm (AAA) repairs. In addition, more complex juxtarenal, pararenal, and suprarenal (JPS) AAAs are being managed with various endovascular techniques. This study sought to evaluate the evolving trends in endovascular aneurysm repair (EVAR) of AAAs, hypothesizing increased rate of JPS AAA repair by EVAR. We also sought to evaluate the risk for morbidity and mortality for EVAR and open aneurysm repair (OAR) of JPS AAAs over time. METHODS: The 2011-2017 American College of Surgeons National Surgical Quality Improvement Program Procedure-Targeted Vascular database was queried for patients undergoing OAR or EVAR for AAAs. A multivariable logistic regression analysis was performed for both infrarenal and JPS AAA repairs. RESULTS: Of 18,661 patients who underwent AAA repair, 3,941 (21.1%) were OAR and 14,720 (78.9%) were EVAR. The rate of OAR decreased from 29.5% in 2011 to 21.3% in 2017 (P < 0.001) with a geometric-mean-annual decrease of 27.8%. The rate of EVAR increased from 70.5% to 78.7% during the same time period (P < 0.001) with a geometric-mean-annual increase of 11.6%. These trends remained true for both infrarenal and JPS AAAs. After adjusting for covariates, there was no difference in associated risk of 30-day mortality, renal complications, or ischemic colitis for either OAR or EVAR over each incremental year for infrarenal AAAs (P > 0.05). However, in patients undergoing EVAR for JPS AAAs, the associated risk of mortality increased with each incremental year (odds ratio [OR]: 1.30, confidence interval [CI]: 1.01-1.69, P = 0.039), whereas there was no difference in the risk of mortality for OAR of JPS AAAs with each incremental year (OR: 1.11, CI: 0.99-1.23, P = 0.067). CONCLUSIONS: The rate of OAR for AAA has decreased over the past seven years with an increase in EVAR, particularly for more complex JPS AAAs. The associated risk for morbidity and mortality for treatment of infrarenal AAAs was not significantly affected by this increased utility of EVAR. The associated risk of mortality for JPS AAAs treated by EVAR increased over time, whereas this trend for associated risk of mortality was not seen for OAR of JPS AAAs. These findings, especially the increased associated risk of mortality over time with EVAR for JPS AAAs, warrant careful prospective analysis.

Predictors of blunt abdominal aortic injury in trauma patients and mortality analysis.

OBJECTIVE: Blunt abdominal aortic injury (BAAI) occurs in less than 0.1% of blunt traumas. A previous multi-institutional study found an associated mortality rate of 39%. We sought to identify risk factors for BAAI and risk factors for mortality in patients with BAAI using a large national database. We hypothesized that an Injury Severity Score of 25 or greater, and thoracic trauma would both increase the risk of mortality in patients with BAAI. METHODS: The Trauma Quality Improvement Program (2010-2016) was queried for individuals with blunt trauma. Patients with and without BAAI were compared. Covariates were included in a multivariable logistic regression model to determine mechanisms of injury, examination findings, and concomitant injuries associated with increased risk for BAAI. An additional multivariable analysis was performed for mortality in patients with BAAI. RESULTS: From 1,056,633 blunt trauma admissions, 1012 (0.1%) had BAAI. The most common mechanism of injury was motor vehicle accident (MVA; 57.5%). More than one-half the patients had at least one rib fracture (54.0%), or a spine fracture (53.9%), whereas 20.8% had hypotension on admission and 7.8% had a trunk abrasion. The average length of stay was 13.4 days and 24.6% required laparotomy, with 6.6% receiving an endovascular repair and 2.9% an open repair. The risk of death in those treated with endovascular vs open repair was similar (P = .28). On multivariable analysis, MVA was the mechanism associated with the highest risk of BAAI (odds ratio [OR], 4.68; 95% confidence interval [CI], 3.87-5.65; P < .001) followed by pedestrian struck (OR, 4.54; 95% CI, 3.47-5.92; P < .001). Other factors associated with BAAI included hypotension on admission (OR, 3.87; 95% CI, 3.21-4.66; P < .001), hemopneumothorax (OR, 3.67; 95% CI, 1.16-11.58; P < .001), abrasion to the trunk (OR, 1.49; 95% CI, 1.15-1.94; P = .003), and rib fracture (OR, 1.46; 95% CI, 1.25-1.70; P < .001). The overall mortality rate was 28.0%. Of the variables examined, the strongest risk factor associated with mortality in patients with BAAI was hemopneumothorax (OR, 12.49; 95% CI, 1.25-124.84; P = .03) followed by inferior vena cava (IVC) injury (OR, 12.05; 95% CI, 2.80-51.80; P < .001). CONCLUSIONS: In the largest nationwide series to date, BAAI continues to have a high mortality rate with hemopneumothorax and IVC injury associated with the highest risk for mortality. The mechanism most strongly associated with BAAI is MVA followed by pedestrian struck. Other risk factors for BAAI include rib fracture and trunk abrasion. Providers must maintain a high suspicion of injury for BAAI when these mechanisms of injury, physical examination or imaging findings are encountered.

Analysis of Endovascular Aneurysm Repair for Small Abdominal Aortic Aneurysms in Males.

BACKGROUND: Current guidelines recommend repair of abdominal aortic aneurysms (AAAs) when ≥5.5 cm. This study sought to evaluate the incidence of male patients undergoing endovascular aneurysm repair (EVAR) for AAAs of various diameters (small <4 cm; intermediate 4-5.4 cm; standard ≥5.5 cm). We analyzed predictors of mortality, hypothesizing that smaller AAAs (<5.5 cm) have no differences in associated risk of mortality compared to standard AAAs (≥5.5 cm). METHODS: The 2011-2017 American College of Surgeons National Surgical Quality Improvement Program Procedure-Targeted Vascular database was queried for male patients undergoing elective EVAR. Patients were stratified by aneurysm diameter. A multivariable logistic regression analysis for clinical outcomes, adjusting for age, clinical characteristics, and comorbidities, was performed. RESULTS: A total of 8037 male patients underwent EVAR with 3926 (48.9%) performed for AAAs <5.5 cm. There was no difference in mortality, readmission, major complications, myocardial infarction, stroke, or ischemic complications among the 3 groups (P > 0.05). In AAAs <5.5 cm, predictors of mortality included prior abdominal surgery (odds ratio [OR], 5.77; confidence interval [CI], 1.38-24.13; P = 0.016), weight loss (OR, 43.4; CI, 3.78-498.7; P = 0.002), disseminated cancer (OR, 17.9; CI, 1.30-245.97; P = 0.031), and diabetes (OR, 6.09; CI, 1.52-24.36; P = 0.011). CONCLUSIONS: Nearly 50% of male patients undergoing elective EVAR were treated for AAAs <5.5 cm. There was no difference in associated risk of mortality for smaller AAAs compared to standard AAAs. The strongest predictors of mortality for patients with smaller AAAs were prior abdominal surgery, weight loss, disseminated cancer, and diabetes.

Sternotomy for Hemorrhage Control in Trauma.

BACKGROUND: Little is known about the injuries, mechanisms, and outcomes in trauma patients undergoing sternotomy for hemorrhage control (SHC). The purpose of this study was to identify predictors of mortality for SHC and provide a descriptive analysis of the use of SHC in trauma. We hypothesize blunt trauma is associated with higher mortality compared with penetrating trauma among trauma patients requiring SHC. METHODS: The Trauma Quality Improvement Program (2013-2016) database was queried for adult patients undergoing SHC within 24 h of admission. Patients with blunt and penetrating trauma were compared using chi-square and Mann-Whitney U-test. A multivariable logistic regression model was used to determine the risk of mortality. RESULTS: Of 584 patients undergoing SHC, 322 (55.1%) were involved in penetrating trauma, and 69 (11.8%) were involved in blunt. The blunt trauma group had a higher median injury severity score (31.5 versus 25.0; P < 0.001) compared with the penetrating group. The median time to hemorrhage control was longer in those with blunt compared with penetrating trauma (84.6 versus 49.8 min; P < 0.001). The mortality rate was higher in patients with blunt compared with penetrating trauma (29.0% versus 12.7%; P < 0.001). However, after adjusting for covariates, there was no difference in risk of mortality between blunt and penetrating trauma (P = 0.06). CONCLUSIONS: Trauma patients requiring SHC after blunt trauma had a higher mortality rate than those in penetrating trauma. After adjusting for predictors of mortality, there was no difference in risk of mortality despite nearly double the time to hemorrhage control in patients presenting after blunt trauma.

Early Tracheostomy for Severe Pediatric Traumatic Brain Injury is Associated with Reduced Intensive Care Unit Length of Stay and Total Ventilator Days.

OBJECTIVES: To determine whether, similar to adults, early tracheostomy in pediatric patients with severe traumatic brain injury (TBI) improves inhospital outcomes including ventilator days, intensive care unit (ICU) length of stay (LOS), and total hospital LOS when compared to late tracheostomy. DESIGN: Retrospective cohort analysis. SETTING: The Pediatric Trauma Quality Improvement Program (TQIP) database. PATIENTS: One hundred twenty-seven pediatric patients <16 years old with severe (>3) abbreviated injury scale TBI who underwent early (days 1-6) or late (day ≥7) tracheostomy between 2014 and 2016. INTERVENTIONS: Not applicable. MEASUREMENTS AND MAIN RESULTS: The Pediatric TQIP database was queried for patients <16 years old with severe TBI, who underwent tracheostomy. Patient demographics and outcomes of early versus late tracheostomy were compared using Student t test, Mann-Whitney U test, and χ2 analysis. Sixteen patients underwent early tracheostomy while 111 underwent late tracheostomy. The groups had similar distributions of age, gender, mechanism of injury, and mean injury severity scores (P > .05). Early tracheostomy was associated with decreased ICU LOS (early: 17 vs late: 32 days, P < .05) and ventilator days (early: 9.7 vs late: 27.1 days, P < .05). There was no difference in total LOS (early: 26.7 vs late: 41.3 days, P = .06), the incidence of acute respiratory distress syndrome (early: 6.3% vs late: 2.7%, P = .45), pneumonia (early: 12.5% vs late: 29.7%, P = .15), or mortality (early: 0% vs late: 2%, P = .588) between the 2 groups. CONCLUSION: Similar to adults, early tracheostomy in pediatric patients with severe TBI is associated with decreased ICU LOS and ventilator days. Future prospective trials are needed to confirm these findings. ARTICLE TWEET: Early tracheostomy in pediatric patients with severe TBI is associated with decreased ICU LOS and ventilator days.

Intracranial pressure monitoring associated with increased mortality in pediatric brain injuries.

BACKGROUND: Utilization of ICP monitors for pediatric patients is low and varies between centers. We hypothesized that in more severely injured patients (GCS 3-4), there would be a decreased mortality associated with invasive monitoring devices. METHODS: The pediatric Trauma Quality Improvement Program (TQIP) was queried for patients aged ≤ 16 years meeting criteria for invasive monitors. Our primary outcome was mortality. Patients with ICP monitoring were compared to those without. A logistic regression was used to examine the risk of mortality. RESULTS: Of 3,808 patients, 685 (18.0%) underwent ICP monitoring. ICP monitors were associated with increased risk of mortality (OR 1.82, CI 1.36-2.44, p < 0.001). A secondary analysis including type of invasive ICP monitor and dividing GCS into 3 categories revealed both intraventricular drain (OR 1.89, CI 1.3-2.7, p = 0.001) and intraparenchymal pressure monitor (OR 1.86, CI 1.32-2.6, p < 0.001) to be independently associated with an increased likelihood of mortality regardless of GCS, while intraparenchymal oxygen monitoring was not (OR 0.47, CI 0.11-2.05, p = 0.316). The strongest effect was seen in those patients with a GCS of 5-6. CONCLUSION: ICP monitors are an independent risk factor for mortality, particularly with intraventricular drains and intraparenchymal monitors in patients with a GCS 5-6.

Non-Accidental Trauma Associated with Withdrawal of Life-Sustaining Medical Treatment in Severe Pediatric Traumatic Brain Injury.

INTRODUCTION: In highly developed countries, as many as 16 percent of children are physically abused each year. Traumatic brain injury (TBI) is the most common injury in non-accidental trauma (NAT) and is responsible for 80 percent of fatal NAT cases, with most deaths occurring in children younger than three years old. Cases of abusers who refuse withdrawal of life-sustaining medical treatment (LSMT) to avoid criminal charges have previously been reported. Therefore, we hypothesized that NAT is associated with a lower risk for withdrawal LSMT in pediatric TBI. METHODS: The pediatric Trauma Quality Improvement Program database was analyzed (2014 to 2016) for patients aged 16 and younger with TBI and Glasgow Coma Scale (GCS) of 8 and lower on admission. Patients with a head Abbreviated Injury Scale (AIS) of 2 or less or who died within 48 hours were excluded. A multivariable logistic regression model was used for analysis. RESULTS: Of 2,209 TBI patients, 92 (4.2 percent) had withdrawal of LSMT. Compared to those without withdrawal of LMST, those with LMST had statistically similar median age (three years of age versus seven years) and a higher rate of NAT (33.7 percent versus 13.5 percent). The most common specified perpetrator was a father/stepfather/male partner (70 percent). After adjusting for covariates, factors associated with higher risk for withdrawal of LSMT included age of less than three years (OR 2.38, CI 1.34-4.23) and NAT (OR 1.86, CI 1.02-3.41). CONCLUSION: NAT is associated with increased risk for withdrawal of LSMT in pediatric TBI. Age of less than three years is similarly associated with a higher risk for withdrawal of LSMT. Future research in this population is needed to determine what other factors predict withdrawal of LSMT and what resources, such as social workers and/or ethics consults, are utilized.

Helicopter Transport Has Decreased Over Time and Transport From Scene or Hospital Matters.

OBJECTIVE: Several reports have found helicopter emergency medical services (HEMS) to be associated with a lower risk of mortality compared with ground emergency medical services (GEMS); however, most studies did not control for transport time or stratify interfacility versus scene. We hypothesize that the HEMS transport rate has decreased nationally and that the risk of mortality for HEMS is similar to GEMS when adjusting for transport time and stratifying by scene or interfacility. METHODS: The Trauma Quality Improvement Program (2010-2016) was queried for adult patients transported by HEMS or GEMS. Multivariable logistic regression was used. RESULTS: The HEMS transport rate decreased by 38.2% from 2010 to 2016 (P < .001). After controlling for known predictors of mortality and transport time, HEMS was associated with a decreased risk of mortality compared with GEMS for adult trauma patient transports (odds ratio = 0.74; 95% confidence interval [CI], 0.71-0.77; P < .001). Compared with GEMS, HEMS transports from the scene were associated with a decreased risk of mortality (OR = 0.63; 95% CI, 0.60-0.66; P < .001), whereas HEMS interfacility transfer was associated with an increased risk of mortality (OR = 1.22; 95% CI, 1.14-1.31; P < .001). CONCLUSION: The rate of HEMS transports in trauma has decreased by nearly 40% over the past 7 years. Our results suggest that HEMS use for scene transports is beneficial for the survival of trauma patients.

Decreased incidence of venous thromboembolism found in trauma patients with positive blood alcohol concentration on admission.

BACKGROUND: The reported incidence of venous thromboembolism (VTE) disease in trauma is 1-58% and is considered a preventable cause of mortality. Positive blood alcohol concentration (BAC) is found in 8-45% of trauma admissions; however, its association with VTE is controversial. OBJECTIVES: We hypothesized that a positive BAC on admission would be associated with a lower rate of VTE in a large national database of trauma patients. METHODS: We queried the largest United States trauma registry, National Trauma Data Bank (2007-2015), for any patient with positive BAC on admission. The primary outcome was VTE and the secondary outcome was mortality. A multivariable logistic regression model was used for analysis. RESULTS: From 2,725,032 patients (70.1% male, 29.9% female), 1,800,216 (66.1%) had a negative BAC while 924,816 (33.9%) had a positive BAC. A positive BAC was associated with lower rates of VTE (OR = 0.88, CI = 0.86-0.90, p < 0.001) and mortality (OR = 0.91, CI = 0.90-0.93, p < 0.001). CONCLUSION: In a large national database, trauma patients with a positive BAC were associated with a lower rate of VTE compared to those with negative BAC. Additionally, trauma patients with positive BAC had a lower association with mortality. These findings remained after adjustment of well-known risk factors for VTE and mortality, respectively.
