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.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.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%, P0.001), self-transportation (7.2% vs 2.7%, P0.01), and hospital admission (72.6% and 46.1%, P0.001). There was no difference in all complications and mortality (all P0.05) between the 2 cohorts.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.

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.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.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).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.

Introduction The incidence and factors related to early cognitive impairment (ECI) after mild traumatic brain injury (mTBI) in pediatric trauma patients (PTPs) are unknown. Prior data in the adult population demonstrated an ECI incidence of 51% after mTBI and strong correlation with initial Glasgow Coma Scale (GCS) and Brain Injury Guidelines (BIG) category. Therefore, we hypothesized that ECI is common after mTBI in PTPs and associated with initial GCS and BIG category. Methods A single-center, retrospective review of PTPs (age, 8-17 years) from 2015 to 2019 with intracranial hemorrhage and mTBI (GCS score, 13-15) was performed. Primary outcome was ECI, defined as Ranchos Los Amigos score less than 8. Comparisons between ECI and non-ECI groups regarding Injury Severity Score (ISS), demographics, and cognitive and clinical outcomes were evaluated using χ2 statistics and Wilcoxon rank sum tests. Odds of ECI were evaluated using multivariable logistic regression. Results From 47 PTPs with mTBI, 18 (38.3%) had ECI. Early cognitive impairment patients had a higher ISS than non-ECI patients (19.7 vs. 12.6, p = 0.003). Injuries involving motor vehicles were more often related to ECI than non-auto-involved mechanisms (55% vs. 15%, p = 0.005). Lower GCS score (odds ratio [OR], 6.60; 95% confidence interval [CI], 1.34-32.51, p = 0.02), higher ISS (OR, 1.12; 95% CI, 1.01-1.24; p = 0.030), and auto-involved injuries (OR, 6.06; 95% CI, 1.15-31.94; p = 0.030) were all associated with increased risk of ECI. There was no association between BIG category and risk of ECI (p > 0.05). Conclusion Nearly 40% of PTPs with mTBI suffer from ECI. Lower initial GCS score, higher ISS, and autoinvolved mechanism of injury were associated with increased risk of ECI. Brain Injury Guidelines category was not associated with ECI in pediatric patients. Level of evidence Prognostic study, Level III.

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 (TQIP) has established a standard of antibiotic administration within one-hour of arrival, but there is a lack of adequately powered studies validating this quality metric. We hypothesize open femur and/or tibia fracture patients undergoing orthopedic surgery have a decreased risk of infectious complications (osteomyelitis, deep and superficial surgical site infection [SSI]) if antibiotics are administered within one-hour of presentation compared to administration after one-hour.The 2019 TQIP was queried for adults with isolated (abbreviated injury scale1 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 one-hour were compared to patients receiving delayed antibiotics (DA) greater than one-hour from arrival.Of 3,367 patients identified, 2,400 (70.4%) received EA. Patients receiving EA had a higher rate of infections compared to 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 in6-hours, blood transfusion and admission vitals, patients in the EA group had a similar associated risk of SSI/osteomyelitis compared to 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 p0.05).In this large national analysis, ~70% of isolated open femur or tibia fracture patients undergoing surgery received antibiotics within one-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 one-hour for open fractures appears warranted.IV (therapeutic).

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.

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.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 grade1 for abbreviated injury scale of the head, face, neck, spine, abdomen, and extremities, were excluded. A multivariable logistic regression analysis was performed.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.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.

Overnight radiology coverage for trauma patients is often addressed with a combination of on-call radiology residents (RR) and a teleradiology service; however, the accuracy of these 2 readers has not been studied for trauma. We aimed to compare the accuracy of RR versus teleradiologist interpretations of CT scans for trauma patients.A retrospective analysis (March 2019 through May 2020) of trauma patients presenting to a single American College of Surgeons Level I trauma center was performed. Patients whose CT scans were performed between 10 pm to 8 am were included, because their scans were interpreted by both a RR and teleradiologist. Interpretations were compared with the final attending faculty radiologist's interpretation and graded for accuracy based on the RADPEER scoring system. Discrepancies were characterized as traumatic injury or incidental findings and missed findings or overcalls. Turnaround time was also compared.A total of 1,053 patients and 8,226 interpretations were included. Compared with teleradiologists, RR had a lower discrepancy (7.7% vs 9.0%, p = 0.026) and major discrepancy rate (3.8% vs 5.2%, p = 0.003). Among major discrepancies, RR had a lower rate of traumatic injury discrepancies (3.2% vs 4.4%, p = 0.004) and missed findings (3.4% vs 5.1%, p0.001), but a higher rate of overcalls (0.5% vs 0.1%, p0.001) compared with teleradiologists. The mean turnaround time was shorter for RR (51.3 vs 78.8 minutes, p0.001). The combination of both RR and teleradiologist interpretations had a lower overall discrepancy rate than RR (5.0% vs 7.7%, p0.001).This study identified lower discrepancy rates and a faster turnaround time by RR compared with teleradiologists for trauma CT studies. The combination of both interpreters had an even lower discrepancy rate, suggesting this combination is optimal when an in-house attending radiologist is not available.

Thyroidectomy is a common operation, performed by general surgeons and otolaryngologists. Few studies compare complication rates between these two specialties. We hypothesized that there would be no difference in the incidence of postoperative complications including recurrent laryngeal nerve (RLN) injury, hypocalcemia, or hematoma based on the surgical specialty performing the thyroidectomy. The 2016–2017 National Surgical Quality Improvement Program Targeted Thyroidectomy database was queried for patients who underwent thyroidectomy for both benign and malignant thyroid diseases. Thyroidectomies performed by general surgeons were compared to those performed by otolaryngologists. Multivariate logistic regression was used to identify risk factors associated with RLN injury, hematoma, and hypocalcemia. From 11,595 patients, 6313 (54.4%) were performed by general surgeons and 5282 (45.6%) by otolaryngologists. Goiter (43.7%) and nodule/neoplasm (40.8%) were the most common indications for the general surgery and otolaryngology cohorts respectively. General surgeons used an energy vessel sealant device more frequently (77.7% vs. 51.5%, p

Background Geriatric burn trauma patients (age ≥65 years) have a 5-fold higher mortality rate than younger adults. With the population of the US aging, the number of elderly burn and trauma patients is expected to increase. A past study using the National Burn Repository revealed a linear increase in mortality for those >65 years old. We hypothesized that octogenarians with burn and trauma injuries would have a higher rate of in-hospital complications and mortality, than patients aged 65-79 years old. Methods The Trauma Quality Improvement Program (2010-2016) was queried for burn trauma patients. To detect mortality risk a multivariable logistic regression model was used. Results From 282 patients, there were 73 (25.9%) octogenarians and 209 (74.1%) aged 65-79 years old. The two cohorts had similar median injury severity scores (16 vs. 15 in octogenarians, P = .81), total body surface area burned ( P = .30), and comorbidities apart from an increased smoking (12.9% vs. 4.1%, P = .04) and decreased hypertension (52.2% vs. 65.8%, P = .04) in the younger cohort. Octogenarians had similar complications, including acute respiratory distress syndrome, pulmonary embolism, deep vein thrombosis ( P > .05), and mortality (15.1% vs. 10.5%, P = .30), compared to the younger cohort. Octogenarians were not associated with an increased mortality risk (odds ratio 1.51, confidence interval 0.24-9.56, P = .67). Discussion Among burn trauma patients ≥65 years, age should not be a sole predictor for mortality risk. Continued research is necessary in order to determine more accurate approaches to prognosticate mortality in geriatric burn trauma patients, such as the validation and refinement of a burn-trauma-related frailty index.

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.

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.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.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).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.

Objectives Disparities in outcomes among trauma patients have been shown to be associated with race and sex. The purpose of this study was to analyze racial and sex mortality disparities in different regions of the United States, hypothesizing that the risk of mortality among black and Asian trauma patients, compared to white trauma patients, will be similar within all regions in the United States. Methods The Trauma Quality Improvement Program (2010-2016) was queried for adult trauma patients, separating by U.S. Census regions. Multivariable logistic regression analyses were performed for each region, controlling for known predictors of morbidity and mortality in trauma. Results Most trauma patients were treated in the South (n = 522 388, 40.7%). After risk adjustment, black trauma patients had a higher associated risk of death in all regions, except the Northeast, compared to white trauma patients. The highest associated risk of death for blacks (vs. whites) was in the Midwest (odds ratio [OR] 1.30, P < .001). Asian trauma patients only had a higher associated risk of death in the West (OR 1.39, P < .001). Male trauma patients, compared to women, had an increased associated risk of mortality in all four regions. Discussion This study found major differences in outcomes among different races within different regions of the United States. There was also both an increased rate and associated risk of mortality for male patients in all regions. Future prospective studies are needed to identify what regional differences in trauma systems including population density, transport times, hospital access, and other trauma resources explain these findings.

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).The Pediatric Trauma Quality Improvement Program (2014-2016) was queried for pediatric (age16 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.From 3693 bicyclists, 3039 (82.3%) were NHBs. Compared with HBs, NHBs were more often Black (21.6% vs 3.8%, P0.001), Hispanic (17.5% vs 9.3%, P0.001), 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%, P0.001). Both groups had similar rates of complications and mortality (P0.05). The associated risk of a serious head (odds ratio = 3.17, P0.001) 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 (P0.05).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.

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.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.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 Score15) decreased from 14.9% in 2014 to 13.5% in 2016 and major trauma (Injury Severity Score15) 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.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.

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.The Trauma Quality Improvement Program (2010-2016) was queried for adult patients transported by HEMS or GEMS. Multivariable logistic regression was used.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).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.

BackgroundGiven the growing number of people worldwide living with human immunodeficiency virus (HIV), a larger subset of these patients are now susceptible to sustaining a traumatic injury. However, the impact of HIV on outcomes in trauma with modern antiretroviral treatment remains unclear.We hypothesized mortality and rates of infectious and inflammatorycomplicationswould be higher in HIV positive (HIV+) trauma patients.MethodsThe Trauma Quality Improvement Programwas queriedtoidentify trauma patients ≥ 18years of age with HIV.Due to the imbalance between HIV+ and HIV negative(HIV-)trauma patients, a 1:2 propensity-matched model was utilized. Matched variables included age, injury severity score, mechanism of injury, systolic blood pressure, pulse rate, Glasgow Coma Scale score, and patient comorbidities.Results84 HIV+ patients were matched to 168 HIV- patients.Compared toHIV-patients, HIV+ patientshad no significant differences in mortality rate (9.5% vs.4.8%, p = 0.144) or infectious complications, including pneumonia (6.0% vs.4.2%, p = 0.530), urinary tract infection (1.2% vs. 1.2%, p = 1.000), or severe sepsis (1.2% vs.0.0%, p = 0.156). However, higher rates of acute respiratory distress syndrome (ARDS) (9.5% vs.0.6%, p

Postoperative neck hematomas following thyroidectomy occur in up to 6.5% of cases. It is unclear whether the use of energy vessel sealant devices effects the rate of PNH. We hypothesized use of an EVSD to be associated with decreased risk of PNH in patients undergoing thyroidectomy. The 2016–2017 American College of Surgeons Thyroidectomy database was queried for patients undergoing thyroidectomy with and without EVSDs. A multivariable logistic regression analysis was performed to evaluate for risk of PNH. From 11,355 patients undergoing thyroidectomy, an EVSD was used for 7460 (65.7%) patients. Age distribution was similar between the two groups (52 vs. 53-years old, p = 0.467). Compared to patients without EVSD used, patients with EVSD used had higher rates of comorbid hypertension (40.6% vs. 34.8%, p

Geriatric trauma patients (GTP) (age ≥ 65years) with blunt splenic injury (BSI) have up to a 6% failure rate of non-operative management (NOM). GTPs failing NOM have a similar mortality rate compared to GTPs managed successfully with NOM. However, it is unclear if this remains true in octogenarians (aged 80-89years). We hypothesized that the failure rate for NOM in octogenarians would be similar to their younger geriatric cohort, patients aged 65-79years; however risk of mortality in octogenarians who fail NOM would be higher than that of octogenarians managed successfully with NOM. The Trauma Quality Improvement Program (2010-2016) was queried for patients with BSI. Those undergoing splenectomy within 6h were excluded to select for patients undergoing NOM. Patients aged 65-79years (young GTPs) were compared to octogenarians. A multivariable logistic regression model was used to determine the risk for failed NOM and mortality. From 43,041 BSI patients undergoing NOM, 3660 (8.5%) were aged 65-79years and 1236 (2.9%) were octogenarians. Both groups had a similar median Injury Severity Score (ISS) (p = 0.10) and failure rate of NOM (6.6% young GTPs vs. 6.8% octogenarians p = 0.82). From those failing NOM, octogenarians had similar units of blood products transfused (p > 0.05) and a higher mortality rate (40.5% vs. 18.2%, p

Patients with severe traumatic brain injury (TBI) are at an increased risk of venous thromboembolism (VTE). Because of concerns of worsening intracranial hemorrhage, clinicians are hesitant to start VTE chemoprophylaxis in this population. We hypothesized that ACS Level I trauma centers would be more aggressive with VTE chemoprophylaxis in adults with severe TBI than Level II centers. We also predicted that Level I centers would have a lower risk of VTE. We queried the Trauma Quality Improvement Program (2010–2016) database for patients with Abbreviated Injury Scale scores of 4 and 5 of the head and compared them based on treating the hospital trauma level. Of 204,895 patients with severe TBI, 143,818 (70.2%) were treated at Level I centers and 61,077 (29.8%) at Level II centers. The Level I cohort had a higher rate of VTE chemoprophylaxis use (43.2% vs 23.3%, P < 0.001) and a shorter median time to chemoprophylaxis (61.9 vs 85.9 hours, P < 0.001). Although Level I trauma centers started VTE chemoprophylaxis more often and earlier than Level II centers, there was no difference in the risk of VTE ( P = 0.414) after controlling for covariates. Future prospective studies are warranted to evaluate the timing, safety, and efficacy of early VTE chemoprophylaxis in severe TBI patients.

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.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.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).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.

BACKDROP The incidence of early cognitive impairment (ECI) after traumatic brain injury (TBI) is unknown. We hypothesized ECI is common and can be predicted based on Glasgow Coma Scale (GCS) and Brain Injury Guideline (BIG) category. METHODS A single-center, retrospective review of adult trauma patients (2014-2016) with intracranial hemorrhage (ICH) and mild TBI (GCS score, 13-15) was performed. The primary outcome was ECI, defined as a Rancho Los Amigos score less than 8. Routine cognitive evaluation is performed on all ICH patients at our institution. Comparisons between ECI and no-ECI groups regarding demographic, cognitive, and clinical outcomes were evaluated using bivariate statistics. The odds of ECI were evaluated using a multivariable logistic regression. RESULTS There were 465 patients with mild TBI, 70.3% were male, and the average age was 53 ± 23 years. The most common mechanism of injury was fall (41.1%) followed by motor vehicle collision (15.9%). The incidence of ECI was 51.4% (n = 239). The incidence in patients with a GCS score of 15 was 42.9%, and BIG 1 category was 42.7%. There were no differences in demographics (age, sex, comorbidities), mechanism of injury, or imaging when comparing ECI patients with no-ECI patients. The GCS score was lower in the ECI group (14.4 vs. 14.7, p < 0.001). Patients with ECI were also less likely to be discharged home (58.2% vs. 78.3%, p < 0.001). Lower GCS-verbal, BIG category 3, and presence of pelvic/extremity fractures were strong risk factors for ECI in a logistic regression model adjusted for age, loss of consciousness, anticoagulants, narcotic administration, and Rotterdam score. CONCLUSION Half of all patients with ICH and mild TBI had ECI. Both lower initial GCS score and BIG category 3 were associated with increased likelihood of ECI. Therefore, we recommend all patients with ICH and mild TBI undergo cognitive evaluation. LEVEL OF EVIDENCE Prognostic Study, Level III.

Pneumonectomy after traumatic lung injury (TLI) is associated with shock, increased pulmonary vascular resistance, and eventual right ventricular failure. Historically, trauma pneumonectomy (TP) mortality rates ranged between 53 and 100%. It is unclear if contemporary mortality rates have improved. Therefore, we evaluated outcomes associated with TP and limited lung resections (LLR) (i.e., lobectomy and segmentectomy) and aimed to identify predictors of mortality, hypothesizing that TP is associated with greater mortality versus LLR. We queried the Trauma Quality Improvement Program (2010-2016) and performed a multivariable logistic regression to determine the independent predictors of mortality in TLI patients undergoing TP versus LLR. TLI occurred in 287,276 patients. Of these, 889 required lung resection with 758 (85.3%) undergoing LLR and 131 (14.7%) undergoing TP. Patients undergoing TP had a higher median injury severity score (26.0 vs. 24.5, p = 0.03) but no difference in initial median systolic blood pressure (109 vs. 107 mmHg, p = 0.92) compared to LLR. Mortality was significantly higher for TP compared to LLR (64.9% vs 27.2%, p

BACKGROUND:The utilization and impact of various ratios of transfusions for pediatric trauma patients (PTPs) receiving a massive transfusion (MT) are unknown. Therefore, we sought to determine the risk for mortality in PTPs receiving an MT of ≥ 6 units of packed red blood cells (PRBC) within 24 h. We compared PRBC: plasma ratio of > 2:1 (Unbalanced Ratios, UR) versus ≤ 2:1 (Balanced Ratios, BR), hypothesizing decreased risk of mortality with BR. METHODS:The Trauma Quality Improvement Program was queried (2014-2016) for PTPs receiving a MT. A multivariable logistic regression model was used to determine risk of mortality. RESULTS:From 239 PTPs receiving an MT, 98 (41%) received an UR, whereas 141 (59%) received a BR. The median ratios, respectively, were 2.7:1 and 1.2:1. Compared to BR patients, UR patients had no differences in injury severity score (ISS), hypotension on admission, and intensive care unit stay (all p > 0.05). The mortality rates for BR and UR were similar (46.1% vs. 52.0%, p = 0.366). Controlling for age, ISS, and severe head injury, UR demonstrated similar risk of mortality compared to BR (p = 0.276). Additionally, ≥ 4:1 ratio versus ≤ 2:1 showed no difference in associated risk of mortality (p = 0.489). CONCLUSION:In contrast to adult studies, this study demonstrated that MT ratios of > 2:1 and even ≥ 4:1 were associated with similar mortality compared to BR for PTPs. These results suggest pediatric MT resuscitation may not require strict BR as has been shown beneficial in adult trauma patients. Future prospective studies are needed to evaluate the optimal ratio for PTP MT resuscitation. LEVEL OF EVIDENCE:III; Retrospective Care Management Study.

PurposeThe 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.MethodsThe 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.ResultsFrom 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. 7days, p

BACKGROUND: This study aimed to evaluate the patterns of firearm violence against children before and after the COVID-19 pandemic, as well as the patterns of specific types of firearm violence against children over time (2016-2020). METHODS: Retrospective firearm violence data were obtained from the Gun Violence Archive. The rate of firearm violence was weighted per 100,000 children. A scatterplot was created to depict the rate of total annual child-involved shooting incidents over time; with a linear trendline fit to 2016 to 2019 data to show projected versus actual 2020 firearm violence. All 50 states were categorized into either strong gun law (n = 25) or weak gun law (n = 25) cohorts. Multivariate linear regressions were performed for number of child-involved shootings over time. RESULTS: There were a total of 1,076 child-involved shootings in 2020, 811 in 2019, and 803 in 2018. The median total child-involved shooting incidents per month per 100,000 children increased from 2018 to 2020 (0.095 vs. 0.124, p = 0.003) and from 2019 to 2020 (0.097 vs. 0.124, p = 0.010). Child killed by adult incidents also increased in 2020 compared with 2018 (p = 0.024) and 2019 (p = 0.049). The scatterplot demonstrates that total child-involved shootings in addition to both fatal and nonfatal firearm violence incidents exceeded the projected number of incidents extrapolated from 2016 to 2019 data. Multivariate linear regression demonstrated that, compared with weak gun law states, strong gun law states were associated with decreased monthly total child-involved shooting incidents between 2018 and 2020 (p < 0.001), as well as between 2019 and 2020 (p < 0.001). CONCLUSION: Child-involved shooting incidents increased significantly in 2020 surrounding the COVID-19 pandemic. Given that gun law strength was associated with a decreased rate of monthly child-involved firearm violence, public health and legislative efforts should be made to protect this vulnerable population from exposure to firearms. LEVEL OF EVIDENCE: Epidemiological, level III.

Background Marijuana has become legal in eight states since 2012. We hypothesized the incidence of marijuana-positive trauma patients and rate of mortality has increased post-legalization. Methods A single level-I trauma center was used to identify patients screening positive for marijuana on urine-toxicology. Patients in the pre-legalization and post-legalization periods were compared. Results In the pre-legalization cohort 9.4% were marijuana-positive versus 11.0% in the post-legalization cohort (p = 0.001). Marijuana-positive patients post-legalization had higher rates of critical trauma activation (20.0% vs. 15.0%, p = 0.01) and mortality (2.6% vs. 1.2%, p = 0.03). In the pediatric (age 12–17) subgroup, the incidence of marijuana-positive patients did not change after legalization (pre: 39.3%, post: 46.4%, p = 0.24). Conclusion The incidence of marijuana-positive trauma patients increased post-legalization. Adult marijuana-positive trauma patients post-legalization were more likely to meet criteria for critical trauma activation and have a higher mortality rate. A subgroup of pediatric patients had an alarmingly high rate of marijuana use. Summary The rate of marijuana use among trauma patients increased post-legalization in California. The rate of critical trauma activation also increased as well as the mortality rate.

BackgroundUtilization of intracranial pressure monitors (ICPMs) has not been consistently shown to improve mortality in patients with severe traumatic brain injury (TBI). A single-center analysis concluded that venous thromboembolism (VTE) chemoprophylaxis (CP) posed no significant bleeding risk in patients following ICPM implementation; however, there is still debate about the optimal use and timing of CP in patients with ICPMs for fear of worsening intracranial hemorrhage. We hypothesized that ICPM use is associated with increased time to VTE CP and thus increased VTE in patients with severe TBI.MethodsA retrospective analysis of the Trauma Quality Improvement Program (2010-2016) was performed to compare severe TBI patients with and without ICPMs. A multivariable logistic regression analysis was completed.ResultsFrom 35,673 patients with severe TBI, 12,487 (35%) had an ICPM. Those with ICPMs had a higher rate of VTE CP (64.3% vs. 49.4%, p

BackgroundThis 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 methodsRetrospective 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.ResultsIn 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&nbsp

Background We sought to develop a novel Prehospital Injury Mortality Score (PIMS) to predict blunt trauma mortality using only prehospital variables. Study Design The 2017 Trauma Quality Improvement Program database was queried and divided into two equal sized sets at random (derivation and validation sets). Multiple logistic regression models were created to determine the risk of mortality using age, sex, mechanism, and trauma activation criterion. The PIMS was derived using the weighted average of each independent predictor. The discriminative power of the scoring tool was assessed by calculating the area under the receiver operating characteristics (AUROC) curve. The PIMS ability to predict mortality was then assessed by using the validation cohort. The score was compared to the Revised Trauma Score (RTS) using the AUROC curve, including a subgroup of patients with normal vital signs. Results The derivation and validation groups each consisted of 163 694 patients. Seven independent predictors of mortality were identified, and the PIMS was derived with scores ranging from 0 to 20. The mortality rate increased from 1.4% to 43.9% and then 100% at scores of 1, 10, and 19, respectively. The model had very good discrimination with an AUROC of .79 in both the derivation and validation groups. When compared to the RTS, the AUROC were similar (.79 vs. .78). On subgroup analysis of patients with normal prehospital vital signs, the PIMS was superior to the RTS (.73 vs. .56). Conclusion The PIMS is a novel scoring tool to predict mortality in blunt trauma patients using prehospital variables. It had improved discriminatory power in blunt trauma patients with normal vital signs compared to the RTS.

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 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 .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.

OBJECTIVE The prevalence of attention deficit hyperactivity disorder (ADHD) in the general pediatric population is 7%, whereas the prevalence in trauma is unknown. We hypothesized pediatric patients with ADHD would have a higher risk of involvement in a mechanism of injury (MOI) requiring constant attention to surroundings, such as a bicycle collision. METHODS The Pediatric Trauma Quality Improvement Program (2014-2016) was queried for patients with ADHD. Patients, less than 16 years of age, with ADHD were compared to those without ADHD. RESULTS The prevalence of ADHD was 2.5% (2,866). ADHD patients had higher risk for bicycle collision (odds ratio [OR], 1.85; 95% confidence interval [CI], 1.59-2.15; p

Smokers with cardiovascular disease have been reported to have decreased mortality compared to non-smokers. Rib fractures are associated with significant underlying injuries such as lung contusions, lacerations, and/or pneumothoraces. We hypothesized that blunt trauma patients with rib fractures who are smokers have decreased ventilator days and risk of in-hospital mortality compared to non-smokers. The Trauma Quality Improvement Program (2010–2016) was queried for patients presenting with a blunt rib fracture. Patients that died within 24 h of admission were excluded. A multivariable logistic regression model was performed. From 282,986 patients with rib fractures, 57,619 (20.4%) were smokers. Compared to non-smokers with rib fractures, smokers had a higher median injury severity score (17 vs. 16, p

Background Perforated peptic ulcer (PPU) surgery mortality ranges 1% to 24%. We hypothesized a decrease in length of stay (LOS) with laparoscopic surgical repair (LSR) compared with open surgical repair (OSR). Methods Patients undergoing PPU surgery 2005 to 2015 were identified in NSQIP. LSR was compared with OSR 2005 to 2015. LSR 2005 to 2010 was compared with 2011 to 2015. OSR 2005 to 2010 was compared with 2011 to 2015. The primary outcome was LOS. Secondary outcomes were mortality and morbidity. Results Between 2005 and 2015, LSR had a decreased LOS, was more likely to wean from the ventilator, but had no significant difference in mortality compared with OSR. There was no significant difference in mortality for LSR or OSR over time. Conclusions When patients are appropriately selected, LSR for PPU is a viable alternative to OSR, decreasing LOS and pulmonary complications. This demonstrates significant benefit to patients and hospital throughput.

Background While the benefit of admission to trauma centers compared to non-trauma centers is well-documented and differences in outcomes between Level-I and Level-II trauma centers are well-studied, data on the differences in outcomes between Level-II trauma centers (L2TCs) and Level-III trauma centers (L3TCs) are scarce. Objectives We sought to compare mortality risk between patients admitted to L2TCs and L3TCs, hypothesizing no difference in mortality risk for patients treated at L3TCs compared to L2TCs. Methods A retrospective analysis of the 2016 Trauma Quality Improvement Program (TQIP) database was performed. Patients aged 18+ years were divided into 2 groups, those treated at American College of Surgeons (ACS) verified L2TCs and L3TCs. Results From 74,486 patients included in this study, 74,187 (99.6%) were treated at L2TCs and 299 (.4%) at L3TCs. Both groups had similar median injury severity scores (ISSs) (10 vs 10, P < .001); however, L2TCs had a higher mean ISS (14.6 vs 11.9). There was a higher mortality rate for L2TC patients (6.0% vs 1.7%, P = .002) but no difference in associated risk of mortality between the 2 groups (OR .46, CI .14-1.50, P = .199) after adjusting predictors of mortality. L2TC patients had a longer median length of stay (5.0 vs 3.5 days, P < .001). There was no difference in other outcomes including myocardial infarction (MI) and cerebrovascular accident (CVA) ( P > .05). Discussion Patients treated at L2TCs had a longer LOS compared to L3TCs. However, after controlling for covariates, there was no difference in associated mortality risk between L2TC and L3TC patients.

Improved survival in trauma patients with acute alcohol intoxication has been previously reported. The effect of illegal and controlled substances on mortality is less clear. We hypothesized that alcohol, illegal and controlled substances are each independently associated with lower odds of mortality in adult trauma patients.The Trauma Quality Improvement Program (2010-2016) was queried for patients screening positive for alcohol, illegal or controlled substances on admission. A multivariate logistic regression analysis was used to determine odds of mortality. A similar analysis was used after stratification by injury severity scale (ISS).From 1,299,705 adult patients, 660,135 were screened for substance use. Of these patients, 497,872 were male, 227,995 (34.5 %) screened positive for alcohol, 155,437 (23.5 %) for illegal substances and 90,259 (13.7 %) for controlled substances. Mortality rate was 6.2 % with alcohol, 5.1 % with illegal substances, and 5.7 % with controlled substances compared to 8.0 % with no substance use (p0.001). After controlling for covariates, all groups had lower odds of mortality: alcohol (OR = 0.88, CI = 0.84-0.92, p0.001), illegal substances (OR = 0.83, CI = 0.77-0.90, p0.001), controlled substances (OR = 0.72, CI = 0.67-0.79, p0.001). When stratified by ISS, alcohol and illegal substances continued to be associated with decreased mortality until ISS 50. Controlled substances were associated with decreased mortality when ISS16.Patients positive for alcohol, illegal or controlled substances have 12 %, 17 %, and 28 % decreased odds of mortality, respectively. This paradoxical association should be confirmed with future clinical studies and merits basic science research to identify biochemical or physiological components conferring a protective effect on survival in trauma patients.

Background Traumatic brain injury (TBI) occurs in approximately 30% of trauma patients. Because neurosurgeons hold expertise in treating TBI, increased neurosurgical staffing may improve patient outcomes. We hypothesized that TBI patients treated at level I trauma centers (L1TCs) with ≥3 neurosurgeons have a decreased risk of mortality vs. those treated at L1TCs with Methods The Trauma Quality Improvement Program database (2010-2016) was queried for patients ≥18 years with TBI. Patient characteristics and mortality were compared between ≥3 and Results Traumatic brain injury occurred in 243 438 patients with 5188 (2%) presenting to L1TCs with Discussion There exists a significant racial disparity in access to neurosurgeon staffing with additional disparities in outcomes based on staffing. Future efforts are needed to improve this chasm of care that exists for trauma patients of color.

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.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.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 age40 years old (odds ratio [OR] = 1.46, 95% confidence interval [CI] [1.41, 1.51],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, with2.5 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.

Objectives: Penetrating abdominal aortic injury (PAAI) is a highly acute injury requiring prompt surgical management. When compared to surgeons at level-II trauma centers, surgeons at level-I trauma centers are more likely to take in-house call, and may more often be available within 15 minutes of patient arrival. Thus, we hypothesized that level-I trauma centers would have a lower mortality rate than level-II trauma centers in patients with PAAI. Methods: We queried the Trauma Quality Improvement Program database for patients with PAAI, and compared patients treated at American College of Surgeons (ACS)-verified level-I centers to those treated at ACS level-II centers. Results: PAAI was identified in 292 patients treated at level-I centers and 86 patients treated at level-II centers. Patients treated at the 2 center types had similar median age, injury severity scores and prevalence of diabetes, hypertension, and smoking (p > 0.05). There was no difference in the frequency of additional intra-abdominal vascular injuries (p > 0.05). Median time to hemorrhage control (level-I: 40.8 vs level-II: 49.2 minutes, p = 0.21) was similar between hospitals at the 2 trauma center levels. We found no difference in the total hospital length of stay or post-operative complications (p > 0.05). When controlling for covariates, we found no difference in the risk of mortality between ACS verified level-I and level-II trauma centers (OR:1.01, CI:0.28-2.64, p = 0.99). Conclusion: Though the majority of PAAIs are treated at level-I trauma centers, we found no difference in the time to hemorrhage control, or the risk of mortality in those treated at level-I centers when compared to those treated at level-II trauma centers. This finding reinforces the ACS-verification process, which strives to achieve similar outcomes between level-I and level-II centers.

Background Isolated diaphragm injury (IDI) occurs in up to 30% of penetrating left thoracoabdominal injuries. Laparoscopic abdominal procedures have demonstrated improved outcome including decreased postoperative pain and length of stay (LOS) compared to open surgery. However, there is a paucity of data on this topic for penetrating IDI. The aim of this study was to examine the prevalence and outcome of laparoscopic diaphragmatic repair versus open diaphragmatic repair (LDR vs ODR) of IDI. Methods The Trauma Quality Improvement Program (2010-2016) was queried for patients with IDI who underwent ODR versus LDR. A bivariate analysis using Pearson chi-square and Mann-Whitney test was performed to determine LOS among the two groups. Results From 2039 diaphragm injuries, 368 patients had IDI; 281 patients (76.4%) underwent ODR and 87 (23.6%) underwent LDR. Compared to LDR, the ODR patients were older (median, 31 vs 25 years, P < .001) and had a higher injury severity score (mean, 11.2 vs 9.6, P = .03) but had similar rates of intensive care unit LOS, unplanned return to the operating room, ventilator days, and complications ( P > .05). Patients undergoing ODR had a longer LOS (5 vs 4 days, P = .01), compared to LDR. There were no deaths in either group. Conclusions Trauma patients presenting with IDI undergoing ODR had a longer hospital LOS compared to patients undergoing LDR with no difference in complications or mortality. Therefore, we recommend when possible an LDR should be employed to decrease hospital LOS. Further research is needed to examine other benefits of laparoscopy such as postoperative pain, incisional hernia, and wound-related complications.

Although previous studies have demonstrated an association between lower extremity fractures and concomitant torso (thorax and abdomen) injuries in trauma patients, they do not compare different types of fractures. Therefore, we investigated the risk of associated torso injuries between femur and tibia/fibula fractures, hypothesizing that trauma patients with femur fractures are at higher risk of torso injuries compared to patients with tibia/fibula fractures.The Trauma Quality Improvement Program database (2010-2016) was queried for patients presenting with either femur or tibia/fibula fractures. Patients with ground-level falls and penetrating injuries were excluded. Univariable and multivariable logistic regression analyses were performed.From 162,354 patients, 104,075 (64.1%) patients had femur fractures and 58,279 (35.9%) had tibia/fibula fractures. Compared to those with femur fractures, patients with tibia/fibula fractures had a higher incidence of torso injuries (32.2% vs. 17.7%, p0.001). The tibia/fibula fracture group was also associated with an increased risk of torso (OR 2.22, CI 2.17-2.27, p0.001), severe (abbreviated injury scale grade3) head (OR 2.38, CI 2.30-2.46, p0.001), and severe spine injuries (OR 2.33, CI 2.07-2.62, p0.001) compared to the femur fracture group. Additionally, patients with tibia/fibula fractures had a higher rate of deep vein thrombosis (2.5% vs. 1.8%, p0.001) than patients with femur fractures.Contrary to previous studies, we demonstrate patients with tibia/fibula fractures have a higher associated risk of torso, severe head and severe spine injuries than patients with femur fractures. Therefore, trauma surgeons should manage tibia/fibula fracture patients with similar clinical vigilance as femur fracture patients.

Background A comparison of outcomes between Level I (LI) and Level II (LII) Trauma Centers (TCs) performing surgical stabilization of rib fracture (SSRF) has not been well described. We sought to compare risk of mortality for patients undergoing SSRF between LI and LII TCs. Methods The Trauma Quality Improvement Program was queried for patients presenting with rib fracture to LI or LII TCs from 2010 to 2015. A multivariable logistic regression analysis was performed. Results 14,046 (7.1%) of 199,020 patients with rib fractures underwent SSRF. SSRF increased from 1304 in 2010 to 3489 in 2015: a geometric mean annual increase of 22%. LI TCs demonstrated a mortality incidence of 1.6% while LII TCs demonstrated a mortality incidence of 1.5% (p > 0.05). There was no statistically significant difference in risk of mortality after SSRF between LI and LII TCs (odds ratio 1.12, confidence interval 0.79–1.59, p-value 0.529). Conclusions Patients undergoing SSRF at LI and LII TCs have no significant difference in risk of mortality. Additionally, there is an annually growing trend across all centers in SSRF performed both for flail and non-flail segments.
