Quantifying the Association Between Surgical Spine Approach and Tracheostomy Timing After Traumatic Cervical Spinal Cord Injury.

BACKGROUND AND OBJECTIVES: Recent evidence suggests earlier tracheostomy is associated with fewer complications in patients with complete cervical spinal cord injury (SCI). This study aims to evaluate the influence of spine surgical approach on the association between tracheostomy timing and in-hospital adverse events treating patients with complete cervical SCI. METHODS: This retrospective cohort study was performed using Trauma Quality Improvement Program data from 2017 to 2020. All patients with acute complete (American Spinal Injury Association-A) cervical SCI who underwent tracheostomy and spine surgery were included. Tracheostomy timing was dichotomized to early (within 1 week after surgery) and delayed (more than 1 week after surgery). Primary outcome was the occurrence of major in-hospital complications. Secondary outcomes included occurrences of immobility-related complications, surgical-site infection, hospital and intensive care unit length of stay, and time on mechanical ventilation. RESULTS: The study included 1592 patients across 358 trauma centers. Mean time to tracheostomy from surgery was 8.6 days. A total of 495 patients underwent anterior approach, 670 underwent posterior approach, and 427 underwent combined anterior and posterior approach. Patients who underwent anterior approach were significantly more likely to have delayed tracheostomy compared with posterior approach (53% vs 40%, P < .001). Early tracheotomy significantly reduced major in-hospital complications (odds ratio 0.67, 95% CI 0.53-0.84) and immobility complications (odds ratio = 0.78, 95% CI 0.6-1.0). Those undergoing early tracheostomy spent 6.0 (95% CI -8.47 to -3.43) fewer days in hospital, 5.7 (95% CI -7.8 to -3.7) fewer days in the intensive care unit, and 5.9 (95% CI -8.2 to -3.7) fewer days ventilated. Surgical approach had no significant negative effect on the association between tracheostomy timing and the outcomes of interest. CONCLUSION: Earlier tracheostomy for patients with cervical SCI is associated with reduced complications, length of stay, and ventilation time. This relationship appears independent of the surgical approach. These findings emphasize that tracheostomy need not be delayed because of the SCI treatment approach.

Robotic Technology in Emergency General Surgery Cases in the Era of Minimally Invasive Surgery.

Importance: Although robotic surgery has become an established approach for a wide range of elective operations, data on its utility and outcomes are limited in the setting of emergency general surgery. Objectives: To describe temporal trends in the use of laparoscopic and robotic approaches and compare outcomes between robotic and laparoscopic surgery for 4 common emergent surgical procedures. Design, Setting, and Participants: A retrospective cohort study of an all-payer discharge database of 829 US facilities was conducted from calendar years 2013 to 2021. Data analysis was performed from July 2022 to November 2023. A total of 1 067 263 emergent or urgent cholecystectomies (n = 793 800), colectomies (n = 89 098), inguinal hernia repairs (n = 65 039), and ventral hernia repairs (n = 119 326) in patients aged 18 years or older were included. Exposure: Surgical approach (robotic, laparoscopic, or open) to emergent or urgent cholecystectomy, colectomy, inguinal hernia repair, or ventral hernia repair. Main Outcomes and Measures: The primary outcome was the temporal trend in use of each operative approach (laparoscopic, robotic, or open). Secondary outcomes included conversion to open surgery and length of stay (both total and postoperative). Temporal trends were measured using linear regression. Propensity score matching was used to compare secondary outcomes between robotic and laparoscopic surgery groups. Results: During the study period, the use of robotic surgery increased significantly year-over-year for all procedures: 0.7% for cholecystectomy, 0.9% for colectomy, 1.9% for inguinal hernia repair, and 1.1% for ventral hernia repair. There was a corresponding decrease in the open surgical approach for all cases. Compared with laparoscopy, robotic surgery was associated with a significantly lower risk of conversion to open surgery: cholecystectomy, 1.7% vs 3.0% (odds ratio [OR], 0.55 [95% CI, 0.49-0.62]); colectomy, 11.2% vs 25.5% (OR, 0.37 [95% CI, 0.32-0.42]); inguinal hernia repair, 2.4% vs 10.7% (OR, 0.21 [95% CI, 0.16-0.26]); and ventral hernia repair, 3.5% vs 10.9% (OR, 0.30 [95% CI, 0.25-0.36]). Robotic surgery was associated with shorter postoperative lengths of stay for colectomy (-0.48 [95% CI, -0.60 to -0.35] days), inguinal hernia repair (-0.20 [95% CI, -0.30 to -0.10] days), and ventral hernia repair (-0.16 [95% CI, -0.26 to -0.06] days). Conclusions and Relevance: While robotic surgery is still not broadly used for emergency general surgery, the findings of this study suggest it is becoming more prevalent and may be associated with better outcomes as measured by reduced conversion to open surgery and decreased length of stay.

Increasing Injury Intensity among 6,500 Violent Deaths in the State of Maryland.

BACKGROUND: Anecdotal evidence strongly suggests there has been a rise in violent crimes. This study sought to examine trends in injury characteristics of homicide victims in Maryland. We hypothesized that there would be an increase in the severity of wound characteristics. STUDY DESIGN: The Office of the Chief Medical Examiner is a statewide agency designated by law to investigate all homicides, suicides, or unusual or suspicious circumstances. Using individual autopsy reports, we collected data among all homicides from 2005 to 2017, categorizing them into 3 time periods: 2005 to 2008 (early), 2009 to 2013 (mid), and 2014 to 2017 (late). Primary outcomes included the number of gunshots, stabs, and fractures from assaults. High-violence intensity outcomes included victims having 10 or more gunshots, 5 or more stabs, or 5 or more fractures from assaults. RESULTS: Of 6,500 homicides (annual range 403 to 589), the majority were from firearms (75%), followed by stabbings (14%) and blunt assaults (10%). Most homicide victims died in the hospital (60%). The average number of gunshots per victim was 3.9 (range 1 to 54), stabs per victim was 9.4 (range 1 to 563), and fractures from assaults per victim was 3.7 (range 0 to 31). The proportion of firearm victims with at least 10 gunshots nearly doubled from 5.7% in the early period to 10% (p < 0.01) in the late period. Similarly, the proportion with 5 or more stabbings increased from 39% to 50% (p = 0.02) and assault homicides with 5 or more fractures increased from 24% to 38% (p < 0.01). CONCLUSIONS: In Maryland, the intensity of violence increased across all major mechanisms of homicide. Further follow-up studies are needed to elucidate the root causes underlying this escalating trend.

Concomitant Traumatic Brain Injury Delays Surgery in Patients With Traumatic Spinal Cord Injury.

BACKGROUND AND OBJECTIVES: Growing evidence supports prompt surgical decompression for patients with traumatic spinal cord injury (tSCI). Rates of concomitant tSCI and traumatic brain injury (TBI) range from 10% to 30%. Concomitant TBI may delay tSCI diagnosis and surgical intervention. Little is known about real-world management of this common injury constellation that carries significant clinical consequences. This study aimed to quantify the impact of concomitant TBI on surgical timing in a national cohort of patients with tSCI. METHODS: Patient data were obtained from the National Trauma Data Bank (2007-2016). Patients admitted for tSCI and who received surgical intervention were included. Delayed surgical intervention was defined as surgery after 24 hours of admission. Multivariable hierarchical regression models were constructed to measure the risk-adjusted association between concomitant TBI and delayed surgical intervention. Secondary outcome included favorable discharge status. RESULTS: We identified 14 964 patients with surgically managed tSCI across 377 North American trauma centers, of whom 2444 (16.3%) had concomitant TBI and 4610 (30.8%) had central cord syndrome (CCS). The median time to surgery was 20.0 hours for patients without concomitant TBI and 24.8 hours for patients with concomitant TBI. Hierarchical regression modeling revealed that concomitant TBI was independently associated with delayed surgery in patients with tSCI (odds ratio [OR], 1.3; 95% CI, 1.1-1.6). Although CCS was associated with delayed surgery (OR, 1.5; 95% CI, 1.4-1.7), we did not observe a significant interaction between concomitant TBI and CCS. In the subset of patients with concomitant tSCI and TBI, patients with severe TBI were significantly more likely to experience a surgical delay than patients with mild TBI (OR, 1.4; 95% CI, 1.0-1.9). CONCLUSION: Concomitant TBI delays surgical management for patients with tSCI. This effect is largest for patients with tSCI with severe TBI. These findings should serve to increase awareness of concomitant TBI and tSCI and the likelihood that this may delay time-sensitive surgery.

Craniotomy versus craniectomy for traumatic acute subdural hematoma-coarsened exact matched analysis of outcomes.

BACKGROUND AND OBJECTIVES: Acute subdural hematoma (aSDH) after traumatic brain injury frequently requires emergent craniotomy (CO) or decompressive craniectomy (DC). We sought to determine the variables associated with either surgical approach and to compare outcomes between matched patients. METHODS: A multi-center retrospective review was used to identify traumatic aSDH patients who underwent CO or DC. Patient variables independently associated with surgical approach were used for coarsened exact matching.Multivariate logistic regression and multivariate Cox proportional-hazards regression wereconducted on matched patients to determine independent predictors of mortality. RESULTS: Seventy-six patients underwent CO and sixty-two underwent DC for aSDH evacuation. DC patients were21.4 years younger (P < 0.001), more likely to be male (80.6 % vs 60.5 %,P = 0.011), and present with GCS ≤ 8 (64.5 % vs 36.8 %,P = 0.001). Age (P < 0.001), epidural hematoma (P = 0.01), skull fracture (P = 0.001), and cisternal effacement (P = 0.02) were independently associated with surgical approach. After coarsened exact matching, DC (P = 0.008), older age (P = 0.007), male sex (P = 0.04), and intraventricular hemorrhage (P = 0.02), were independently associated with inpatient mortality. Multivariate Cox proportional-hazards regression demonstrated that DC was independently associated with mortality at 90-days (P = 0.001) and 1-year post-operation (P = 0.003). CONCLUSION: aSDH patients who receive surgical evacuation via DC as opposed to CO are younger, more likely to be male, and have worse clinical exam. After controlling for patient differences via coarsened exact matching, DC is independently associated with mortality.

Impact of Antithrombotic Medications and Reversal Strategies on the Surgical Management and Outcomes of Traumatic Acute Subdural Hematoma.

OBJECTIVE: Careful hematologic management is required in surgical patients with traumatic acute subdural hematoma (aSDH) taking antithrombotic medications. We sought to compare outcomes between patients with aSDH taking antithrombotic medications at admission who received antithrombotic reversal with patients with aSDH not taking antithrombotics. METHODS: Retrospective review identified patients with traumatic aSDH requiring surgical evacuation. The cohort was divided based on antithrombotic use and whether pharmacologic reversal agents or platelet transfusions were administered. A 3-way comparison of outcomes was performed between patients taking anticoagulants who received pharmacologic reversal, patients taking antiplatelets who received platelet transfusion, and patients not taking antithrombotics. Multivariable regressions, adjusted for injury severity, further investigated associations with outcomes. RESULTS: Of 138 patients who met inclusion criteria, 13.0% (n = 18) reported taking anticoagulants, 16.7% (n = 23) reported taking antiplatelets, and 3.6% (n = 5) reported taking both. Patients taking antiplatelets who received platelet transfusion had longer intraoperative times (P = 0.040) and higher rates of palliative care consultations (P = 0.046) compared with patients taking anticoagulants who received pharmacologic reversal and patients not taking antithrombotics. Across groups, no significant differences were found in frequency of in-hospital intracranial hemorrhage and venous thromboembolism, length of hospital stay, rate of inpatient mortality, or follow-up health status. In multivariable analysis, intraoperative time remained longest for the antiplatelets with platelet transfusion group. Other outcomes were not associated with patient group. CONCLUSIONS: Among surgical patients with traumatic aSDH, those taking antiplatelet medications who receive platelet transfusions experience longer intraoperative procedure times and higher rates of palliative care consultation. Comparable outcomes were observed between patients receiving antithrombotic reversal and patients not taking antithrombotics.

Association Between Geospatial Access to Trauma Center Care and Motor Vehicle Crash Mortality in the United States.

BACKGROUND: Motor vehicle crashes (MVCs) are a leading cause of preventable trauma death in the United States (US). Access to trauma center care is highly variable nationwide. The objective of this study was to measure the association between geospatial access to trauma center care and MVC mortality. METHODS: This was a population-based study of MVC-related deaths that occurred in 3,141 US counties (2017-2020). ACS and state-verified level I-III trauma centers were mapped. Geospatial network analysis estimated the ground transport time to the nearest trauma center from the population-weighted centroid for each county. In this way, the exposure was the predicted access time to trauma center care for each county population. Hierarchical negative binomial regression measured the risk-adjusted association between predicted access time and MVC mortality, adjusting for population demographics, rurality, access to trauma resources, and state traffic safety laws. RESULTS: We identified 92,398 crash fatalities over the four-year study period. Trauma centers mapped included 217 level I, 343 level II, and 495 level III trauma centers. The median county predicted access time was 47 min (IQR 26-71 min). Median county MVC mortality was 12.5 deaths/100,000 person-years (IQR 7.4-20.3 deaths/100,000 person-years). After risk-adjustment, longer predicted access times were significantly associated with higher rates of MVC mortality (>60 min vs. <15 min; MRR 1.36; 95%CI 1.31-1.40). This relationship was significantly more pronounced in urban/suburban vs. rural/wilderness counties (p for interaction, <0.001). County access to trauma center care explained 16% of observed state-level variation in MVC mortality. CONCLUSIONS: Geospatial access to trauma center care is significantly associated with MVC mortality and contributes meaningfully to between-state differences in road traffic deaths. Efforts to improve trauma system organization should prioritize access to trauma center care to minimize crash fatalities. LEVEL OF EVIDENCE: Level III, Epidemiological.

Predictors of initial management failure in traumatic hemothorax: A prospective multicenter cohort analysis.

BACKGROUND: Traumatic hemothorax is common, and management failure leads to worse outcomes. We sought to determine predictive factors and understand the role of trauma center performance in hemothorax management failure. METHODS: We prospectively examined initial hemothorax management (observation, pleural drainage, surgery) and failure requiring secondary intervention in 17 trauma centers. We defined hemothorax management failure requiring secondary intervention as thrombolytic administration, tube thoracostomy, image-guided drainage, or surgery after failure of the initial management strategy at the discretion of the treating trauma surgeon. Patient-level predictors of hemothorax management failure requiring secondary intervention were identified for 2 subgroups: initial observation and immediate pleural drainage. Trauma centers were divided into quartiles by hemothorax management failure requiring secondary intervention rate and hierarchical logistic regression quantified variation. RESULTS: Of 995 hemothoraces in 967 patients, 186 (19%) developed hemothorax management failure requiring secondary intervention. The frequency of hemothorax management failure requiring secondary intervention increased from observation to pleural drainage to surgical intervention (12%, 22%, and 35%, respectively). The number of ribs fractured (odds ratio 1.12 per fracture; 95% confidence interval 1.00-1.26) and pulmonary contusion (odds ratio 2.25, 95% confidence interval 1.03-4.91) predicted hemothorax management failure requiring secondary intervention in the observation subgroup, whereas chest injury severity (odds ratio 1.58; 95% confidence interval 1.17-2.12) and initial hemothorax volume evacuated (odds ratio 1.10 per 100 mL; 95% confidence interval 1.05-1.16) predicted hemothorax management failure requiring secondary intervention after pleural drainage. After adjusting for patient characteristics in the logistic regression model for hemothorax management failure requiring secondary intervention, patients treated at high hemothorax management failure requiring secondary intervention trauma centers were 6 times more likely to undergo an intervention after initial hemothorax management failure than patients treated in low hemothorax management failure requiring secondary intervention trauma centers (odds ratio 6.18, 95% confidence interval 3.41-11.21). CONCLUSION: Failure of initial management of traumatic hemothorax is common and highly variable across trauma centers. Assessing patient selection for a given management strategy and center-level practices represent opportunities to improve outcomes from traumatic hemothorax.

Earlier Tracheostomy Reduces Complications in Complete Cervical Spinal Cord Injury in Real-World Practice: Analysis of a Multicenter Cohort of 2001 Patients.

BACKGROUND AND OBJECTIVES: It is believed that early tracheostomy in patients with traumatic cervical spinal cord injury (SCI) may lessen the risk of developing complications and reduce the duration of mechanical ventilation and critical care stay. This study aims to assess whether early tracheostomy is beneficial in patients with traumatic cervical SCI. METHODS: We conducted a retrospective cohort study using data from the American College of Surgeons Trauma Quality Improvement Program database from 2010 to 2018. Adult patients with a diagnosis of acute complete (ASIA A) traumatic cervical SCI who underwent surgery and tracheostomy were included. Patients were stratified into those receiving early (at or before 7 days) and delayed tracheostomy. Propensity score matching was used to assess the association between delayed tracheostomy and the risk of in-hospital adverse events. Risk-adjusted variability in tracheostomy timing across trauma centers was investigated using mixed-effects regression. RESULTS: The study included 2001 patients from 374 North American trauma centers. The median time to tracheostomy was 9.2 days (IQR: 6.1-13.1 days), with 654 patients (32.7%) undergoing early tracheostomy. After matching, the odds of a major complication were significantly lower for early tracheostomy patients (OR: .90; 95% CI: .88-.98). Patients were also significantly less likely to experience an immobility-related complication (OR: .90; 95% CI: .88-.98). Patients in the early group spent 8.2 fewer days in the critical care unit (95% CI: -10.2 to -6.61) and 6.7 fewer days ventilated (95% CI: -9.44 to -5.23). There was significant variability in tracheostomy timeliness between trauma centers with a median odds ratio of 12.2 (95% CI: 9.7-13.7), which was not explained by case-mix and hospital-level characteristics. CONCLUSION: A 7-day threshold to implement tracheostomy seems to be associated with reduced in-hospital complications, time in the critical care unit, and time on mechanical ventilation.

Open versus percutaneous tube thoracostomy with and without thoracic lavage for traumatic hemothorax: a novel randomized controlled simulation trial.

Objective: To quantify and assess the relative performance parameters of thoracic lavage and percutaneous thoracostomy (PT) using a novel, basic science 2×2 randomized controlled simulation trial. Summary background data: Treatment of traumatic hemothorax (HTX) with open tube thoracostomy (TT) is painful and retained HTX is common. PT is potentially less painful whereas thoracic lavage may reduce retained HTX. Yet, procedural time and the feasibility of combining PT with lavage remain undefined. Methods: A simulated partially clotted HTX (2%-gelatin-saline mixture) was loaded into a TT trainer and then evacuated after randomization to one of four protocols: TT+/-lavage or PT+/-lavage. Standardized inserts with fixed 28-Fr TT or 14-Fr PT positioning were used to minimize tube positioning variability. Lavage consisted of two 500 mL aliquots of warm saline after initial HTX evacuation. The primary outcome was HTX volume evacuated. The secondary outcome was additional procedural time required for the addition of the lavage. Results: A total of 40 simulated HTX trials were randomized. TT alone evacuated a median of 1236 mL (IQR 1168, 1294) leaving a residual volume of 265 mL (IQR 206, 333). PT alone resulted in a significantly greater median residual volume of 588 mL (IQR 497, 646) (p=0.002). Adding lavage resulted in similar residual volumes for TT compared with TT alone but significantly less for PT compared with PT alone (p=0.002). Lavage increased procedural time for TT by a median of 7.0 min (IQR 6.5, 8.0) vs 11.7 min (IQR 10.2, 12.0) for PT (p<0.001). Conclusion: This simulation trial characterized HTX evacuation in a standardized fashion. Adding lavage to thoracostomy placement may improve evacuation, particularly for small-diameter tubes, with little added procedural time. Further prospective clinical study is warranted. Level of evidence: NA.

Emergency department versus operating room intubation of patients undergoing immediate hemorrhage control surgery.

BACKGROUND: Hemorrhage control surgery is an essential trauma center function. Airway management of the unstable bleeding patient in the emergency department (ED) presents a challenge. Premature intubation in the ED can exacerbate shock and precipitate extremis. We hypothesized that ED versus operating room intubation of patients requiring urgent hemorrhage control surgery is associated with adverse outcomes at the patient and hospital-levels. METHODS: Patients who underwent hemorrhage control within 60 minutes of arrival at level 1 or 2 trauma centers were identified (National Trauma Data Bank 2017-2019). To minimize confounding, patients dead on arrival, undergoing ED thoracotomy, or with clinical indications for intubation (severe head/neck/face injury or Glasgow Coma Scale score of ≤8) were excluded. Two analytic approaches were used. First, hierarchical logistic regression measured the risk-adjusted association between ED intubation and mortality. Secondary outcomes included ED dwell time, units of blood transfused, and major complications (cardiac arrest, acute respiratory distress syndrome, acute kidney injury, sepsis). Second, a hospital-level analysis determined whether hospital tendency ED intubation was associated with adverse outcomes. RESULTS: We identified 9,667 patients who underwent hemorrhage control surgery at 253 trauma centers. Patients were predominantly young men (median age, 33 years) who suffered penetrating injuries (71%). The median initial Glasgow Coma Scale and systolic blood pressure were 15 and 108 mm Hg, respectively. One in five (20%) of patients underwent ED intubation. After risk-adjustment, ED intubation was associated with significantly increased odds of mortality, longer ED dwell time, greater blood transfusion, and major complications. Hospital-level analysis identified significant variation in use of ED intubation between hospitals not explained by patient case mix. After risk adjustment, patients treated at hospitals with high tendency for ED intubation (compared with those with low tendency) were significantly more likely to suffer in-hospital cardiac arrest (6% vs. 4%; adjusted odds ratio, 1.46; 95% confidence interval, 1.04-2.03). CONCLUSION: Emergency department intubation of patients who require urgent hemorrhage control surgery is associated with adverse outcomes. Significant variation in ED intubation exists between trauma centers not explained by patient characteristics. Where feasible, intubation should be deferred in favor of rapid resuscitation and transport to the operating room. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

Whole Blood Resuscitation is Safe in Pediatric Trauma Patients: A Multicenter Study.

INTRODUCTION: Whole blood (WB) resuscitation has been associated with a mortality benefit in trauma patients. Several small series report the safe use of WB in the pediatric trauma population. We performed a subgroup analysis of the pediatric patients from a large prospective multicenter trial comparing patients receiving WB or blood component therapy (BCT) during trauma resuscitation. We hypothesized that WB resuscitation would be safe compared to BCT resuscitation in pediatric trauma patients. METHODS: This study included pediatric trauma patients (0-17 y), from ten level-I trauma centers, who received any blood transfusion during initial resuscitation. Patients were included in the WB group if they received at least one unit of WB during their resuscitation, and the BCT group was composed of patients receiving traditional blood product resuscitation. The primary outcome was in-hospital mortality with secondary outcomes being complications. Multivariate logistic regression was performed to assess for mortality and complications in those treated with WB vs BCT. RESULTS: Ninety patients, with both penetrating and blunt mechanisms of injury (MOI), were enrolled in the study (WB: 62 (69%), BCT: 28 (21%)). Whole blood patients were more likely to be male. There were no differences in age, MOI, shock index, or injury severity score between groups. On logistic regression, there was no difference in complications. Mortality was not different between the groups (P = .983). CONCLUSION: Our data suggest WB resuscitation is safe when compared to BCT resuscitation in the care of critically injured pediatric trauma patients.

Modifiable Factors Related to Firearm Homicides: A Broader View of Our Lane.

OBJECTIVE: This study aims to identify modifiable factors related to firearm homicide (FH). SUMMARY BACKGROUND DATA: Many socioeconomic, legislative and behavioral risk factors impact FH. Most studies have evaluated these risk factors in isolation, but they coexist in a complex and ever-changing American society. We hypothesized that both restrictive firearm laws and socioeconomic support would correlate with reduced FH rates. METHODS: To perform our ecologic cross-sectional study, we queried the Centers for Disease Control (CDC) Wide-ranging ONline Data for Epidemiologic Research (WONDER) and Federal Bureau of Investigation (FBI) Uniform Crime Reporting (UCR) for 2013-2016 state FH data. We retrieved firearm access estimates from the RAND State-Level Firearm Ownership Database. Alcohol use and access to care data were captured from the CDC Behavioral Risk Factor Surveillance System (BRFSS). Detached youth rates, socioeconomic support data and poverty metrics were captured from US Census data for each state in each year. Firearm laws were obtained from the State Firearms Law Database. Variables with significant FH association were entered into a final multivariable panel linear regression with fixed effect for state. RESULTS: A total of 49,610 FH occurred in 2013-2016 (median FH rate: 3.9:100,000, range: 0.07-11.2). In univariate analysis, increases in concealed carry limiting laws ( P =0.012), detached youth rates ( P <0.001), socioeconomic support ( P <0.001) and poverty rates ( P <0.001) correlated with decreased FH. Higher rates of heavy drinking ( P =0.036) and the presence of stand your ground doctrines ( P =0.045) were associated with increased FH. Background checks, handgun limiting laws, and weapon access were not correlated with FH. In multivariable regression, increased access to food benefits for those in poverty [ß: -0.132, 95% confidence interval (CI): -0.182 to -0.082, P <0.001] and laws limiting concealed carry (ß: -0.543, 95% CI: -0.942 to -0.144, P =0.008) were associated with decreased FH rates. Allowance of stand your ground was associated with more FHs (ß: 1.52, 95% CI: 0.069-2.960, P <0.040). CONCLUSIONS: The causes and potential solutions to FH are complex and closely tied to public policy. Our data suggests that certain types of socioeconomic support and firearm restrictive legislation should be emphasized in efforts to reduce firearm deaths in America.

Proceedings from the 2022 Consensus Conference to Implement Optimal Venous Thromboembolism Prophylaxis in Trauma.

ABSTRACT: On May 4 and 5, 2022, a meeting of multidisciplinary stakeholders in the prevention and treatment of venous thromboembolism (VTE) after trauma was convened by the Coalition for National Trauma Research, funded by the National Heart, Lung, and Blood Institute of the National Institutes of Health, and hosted by the American College of Surgeons in Chicago, Illinois. This consensus conference gathered more than 40 in-person and 80 virtual attendees, including trauma surgeons, other physicians, thrombosis experts, nurses, pharmacists, researchers, and patient advocates. The objectives of the meeting were twofold: (1) to review and summarize the present state of the scientific evidence regarding VTE prevention strategies in injured patients and (2) to develop consensus on future priorities in VTE prevention implementation and research gaps.To achieve these objectives, the first part of the conference consisted of talks from physician leaders, researchers, clinical champions, and patient advocates to summarize the current state of knowledge of VTE pathogenesis and prevention in patients with major injury. Video recordings of all talks and accompanying slides are freely available on the conference website ( https://www.nattrauma.org/research/research-policies-templates-guidelines/vte-conference/ ). Following this curriculum, the second part of the conference consisted of a series of small-group breakout sessions on topics potentially requiring future study. Through this process, research priorities were identified, and plans of action to develop and undertake future studies were defined.The 2022 Consensus Conference to Implement Optimal VTE Prophylaxis in Trauma answered the National Trauma Research Action Plan call to define a course for future research into preventing thromboembolism after trauma. A multidisciplinary group of clinical champions, physicians, scientists, and patients delineated clear objectives for future investigation to address important, persistent key knowledge gaps. The series of papers from the conference outlines the consensus based on the current literature and a roadmap for research to answer these unanswered questions.
