Impact of catastrophic brain injury guidelines on organ donation rates: Results of an EAST multicenter trial.

BACKGROUND: One third of organ donors suffer catastrophic brain injury (CBI). There are no standard guidelines for the management of traumatic CBI prior to brain death, and not all trauma centers have institutional CBI guidelines. In addition, there is high variability in management between institutions with guidelines. Catastrophic brain injury guidelines vary and may include various combinations of hormone therapy, vasopressors, fluid resuscitation, and other practices. We hypothesized that centers with CBI guidelines have higher organ donation rates than those without. METHODS: This prospective, observational EAST-sponsored multicenter trial included adult (18+ years old) traumatic-mechanism CBI patients at 33 level I and II trauma centers from January 2022 to May 2023. Catastrophic brain injury was defined as a brain injury causing loss of function above the brain stem and subsequent death. Cluster analysis with linear mixed-effects model including UNOS regions and hospital size by bed count was used to determine whether CBI guidelines are associated with organ donation. RESULTS: A total of 790 CBI patients were included in this analysis. In unadjusted comparison, CBI guideline centers had higher rates of organ donation and use of steroids, whole blood, and hormone therapy. In a linear mixed-effects model, CBI guidelines were not associated with organ donation. Registered organ donor status, steroid hormones, and vasopressin were associated with increased relative risk of donation. CONCLUSION: There is high variability in management of CBI, even at centers with CBI guidelines in place. While the use of institutional CBI guidelines was not associated with increased organ donation, guidelines in this study were not identical. Hormone replacement with steroids and vasopressin was associated with increased donation. Hormone resuscitation is a common feature of CBI guidelines. Further analysis of individual practices that increase organ donation after CBI may allow for more effective guidelines and an overall increase in donation to decrease the long waiting periods for organ transplant recipients. LEVEL OF EVIDENCE: Prognostic; Level III.

Stop the Bleed-Wait for the Ambulance or Get in the Car and Drive? A Post Hoc Analysis of an EAST Multicenter Trial.

Background: The Stop the Bleed campaign gives bystanders an active role in prehospital hemorrhage control. Whether extending bystanders' role to private vehicle transport (PVT) for urban penetrating trauma improves survival is unknown, but past research has found benefit to police and PVT. We hypothesized that for penetrating trauma in an urban environment, where prehospital procedures have been proven harmful, PVT improves outcomes compared to any EMS or advanced life support (ALS) transport.Methods: Post-hoc analysis of an EAST multicenter trial was performed on adult patients with penetrating torso/proximal extremity trauma at 25 urban trauma centers from 5/2019-5/2020. Patients were allocated to PVT and any EMS or ALS transport using nearest neighbor propensity score matching. Univariate analyses included Wilcoxon signed rank or McNemar's Test and logistic regression.Results: Of 1999 penetrating trauma patients in urban settings, 397 (19.9%) had PVT, 1433 (71.7%) ALS transport, and 169 (8.5%) basic life support (BLS) transport. Propensity matching yielded 778 patients, distributed equally into balanced groups. PVT patients were primarily male (90.5%), Black (71.2%), and sustained gunshot wounds (68.9%). ALS transport had significantly higher ED mortality (3.9% vs 1.9%, P = 0.03). There was no difference in in-hospital mortality rate, hospital LOS, or complications for all EMS or ALS only transport patients.Conclusion: Compared to PVT, ALS, which provides more prehospital procedures than BLS, provided no survival benefit for penetrating trauma patients in urban settings. Bystander education incorporating PVT for early arrival of penetrating trauma patients in urban settings to definitive care merits further investigation.

N-Butyl-2-Cyanoacrylate Adhesive Versus Absorbable Tacks in Laparoscopic Groin Hernia Repair: A Multicenter Randomized Clinical Trial.

Objective: We aimed to determine whether n-butyl-2-cyanoacrylate (NB2C) adhesive is a safe and effective mechanism for nonpenetrating mesh and peritoneal fixation during laparoscopic groin hernia repair. Background: Chronic pain after laparoscopic groin hernia repair has been associated with penetrating fixation, but there had been no US Food and Drug Administration-approved devices for nonpenetrating fixation in this context. Methods: Patients undergoing laparoscopic transabdominal preperitoneal (TAP) or totally extraperitoneal (TEP) groin hernia repair with mesh at 1 of 5 academic medical centers were randomized to mesh (TAP/TEP) and peritoneal (TAP) fixation with NB2C adhesive or absorbable tacks. The primary outcome was improvement in pain (visual analog scale [VAS]) at 6 months. The noninferiority margin was 0.9 (α = 0.025; ß = 80%). Recurrence, successful use of the device, quality of life, and rates of adverse events (AEs) were secondary outcomes. Results: From 2019 to 2021, 284 patients were randomized to either NB2C adhesive or absorbable tacks (n = 142/142). Patient and hernia characteristics were comparable, and 65% were repaired using a TAP approach. The difference in VAS improvement at 6 months with NB2C adhesive was not inferior to absorbable tacks in intention-to-treat and per-protocol analyses, respectively (0.25 [95% CI, -0.33 to 0.82]; P = 0.013; 0.22 [95% CI, -0.36 to 0.80], noninferiority P = 0.011). There were no differences in secondary outcomes including recurrence, successful use of each device to fixate the mesh and peritoneum, quality of life, and additional VAS pain scores. Rates of adverse and serious AEs were also comparable. Conclusions: NB2C adhesive is safe and effective for mesh fixation and peritoneal closure during laparoscopic groin hernia repair.

Tranexamic Acid and Pulmonary Complications: A Secondary Analysis of an EAST Multicenter Trial.

BACKGROUND: Anti-inflammatory effects of tranexamic acid (TXA) in reducing trauma endotheliopathy may protect from acute lung injury. Clinical data showing this benefit in trauma patients is lacking. We hypothesized that TXA administration mitigates pulmonary complications in penetrating trauma patients. MATERIALS AND METHODS: This is a post-hoc analysis of a multicenter, prospective, observational study of adults (18+ years) with penetrating torso and/or proximal extremity injury presenting at 25 urban trauma centers. Tranexamic acid administration in the prehospital setting or within three hours of admission was examined. Participants were propensity matched to compare similarly injured patients. The primary outcome was development of pulmonary complication (ARDS and/or pneumonia). RESULTS: A total of 2382 patients were included, and 206 (8.6%) received TXA. Of the 206, 93 (45%) received TXA prehospital and 113 (55%) received it within three hours of hospital admission. Age, sex, and incidence of massive transfusion did not differ. The TXA group was more severely injured, more frequently presented in shock (SBP < 90 mmHg), developed more pulmonary complications, and had lower survival (P < 0.01 for all). After propensity matching, 410 patients remained (205 in each cohort) with no difference in age, sex, or rate of shock. On logistic regression, increased emergency department heart rate was associated with pulmonary complications. Tranexamic acid was not associated with different rate of pulmonary complications or survival on logistic regression. Survival was not different between the groups on logistic regression or propensity score-matched analysis. CONCLUSIONS: Tranexamic acid administration is not protective against pulmonary complications in penetrating trauma patients.

Isolated injury, Charlson Comorbidity Index, and transfer from another facility are associated with delay in antibiotic administration: a retrospective study of 963 patients with open fractures.

Purpose: To identify factors associated with delays in administration and pharmacy and nursing preparation of antibiotics for patients with open fractures. Design: Retrospective review. Setting: Level I trauma center. Patients: Nine hundred sixty-three adults with open fractures administered antibiotics. Main Outcome Measurements: Delay in antibiotic administration greater than 66 minutes from arrival and significant pharmacy-related and nursing-related delay. Results: Isolated injury, Charlson Comorbidity Index, and transfer from another facility were associated with delay in antibiotic administration greater than 66 minutes. Injury Severity Score, transfer, and trauma team activation were associated with pharmacy-related or nursing-related delay. Conclusion: Interventions to reduce antibiotic administration time for open fractures should focus on early identification of open fractures and standardization of antibiotic protocols to ensure timely administration even in complex or resource-scarce care situations. Level of Evidence: Prognostic level III.

Does Scheduled Low-Dose Short-Term NSAID (Ketorolac) Modulate Cytokine Levels After Orthopaedic Polytrauma? A Secondary Analysis of a Randomized Clinical Trial.

OBJECTIVES: To determine whether scheduled low-dose, short-term ketorolac modulates cytokine concentrations in orthopaedic polytrauma patients. DESIGN: Secondary analysis of a double-blinded, randomized controlled trial. SETTING: Single Level I trauma center from August 2018 to October 2022. PATIENT SELECTION CRITERIA: Orthopaedic polytrauma patients between 18 and 75 years with a New Injury Severity Score greater than 9 were enrolled. Participants were randomized to receive 15 mg of intravenous ketorolac every 6 hours for up to 5 inpatient days or 2 mL of intravenous saline similarly. OUTCOME MEASURES AND COMPARISONS: Daily concentrations of prostaglandin E2 and interleukin (IL)-1a, IL-1b, IL-6, and IL-10. Clinical outcomes included hospital and intensive care unit length of stay, pulmonary complications, and acute kidney injury. RESULTS: Seventy orthopaedic polytrauma patients were enrolled, with 35 participants randomized to the ketorolac group and 35 to the placebo group. The overall IL-10 trend over time was significantly different in the ketorolac group ( P = 0.043). IL-6 was 65.8% higher at enrollment compared to day 3 ( P < 0.001) when aggregated over both groups. There was no significant treatment effect for prostaglandin E2, IL-1a, or IL-1b ( P > 0.05). There were no significant differences in clinical outcomes between groups ( P > 0.05). CONCLUSIONS: Scheduled low-dose, short-term, intravenous ketorolac was associated with significantly different mean trends in IL-10 concentration in orthopaedic polytrauma patients with no significant differences in prostaglandin E2, IL-1a, IL-1b, or IL-6 levels between groups. The treatment did not have an impact on clinical outcomes of hospital or intensive care unit length of stay, pulmonary complications, or acute kidney injury. LEVEL OF EVIDENCE: Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

Optimal strategies for assessing and managing pain, agitation, and delirium in the critically ill surgical patient: What you need to know.

ABSTRACT: Pain, agitation, and delirium (PAD) are primary drivers of outcome in the ICU, and expertise in managing these entities successfully is crucial to the intensivist's toolbox. In addition, there are unique aspects of surgical patients that impact assessment and management of PAD. In this review, we address the continuous spectrum of assessment, and management of critically ill surgical patients, with a focus on limiting PAD, particularly incorporating mobility as an anchor to ICU liberation. Finally, we touch on the impact of PAD in specific populations, including opioid use disorder, traumatic brain injury, pregnancy, obesity, alcohol withdrawal, and geriatric patients. The goal of the review is to provide rapid access to information regarding PAD and tools to assess and manage these important elements of critical care of surgical patients.

Prehospital shock index predicts outcomes after prolonged transport: A multicenter rural study.

BACKGROUND: Shock index (SI) predicts outcomes after trauma. Prior single-center work demonstrated that emergency medical services (EMSs) initial SI was the most accurate predictor of hospital outcomes in a rural environment. This study aimed to evaluate the predictive ability of SI in multiple rural trauma systems with prolonged transport times to a definitive care facility. METHODS: This retrospective review was performed at four American College of Surgeons-verified level 1 trauma centers with large rural catchment basins. Adult trauma patients who were transferred and arrived >60 minutes from scene during 2018 were included. Patients who sustained blunt chest or abdominal trauma were analyzed. Subjects with missing data or severe head trauma (Abbreviated Injury Scale score, >2) were excluded. Poisson and binomial logistic regression were used to study the effect of SI and delta shock index (∆SI) on outcomes. RESULTS: After applying the criteria, 789 patients were considered for analysis (502 scene patients and 287 transfers). The mean Injury Severity Score was 8 (interquartile range, 6) for scene and 8.9 (interquartile range, 5) for transfers. Initial EMSs SI was a significant predictor of the need for blood transfusion and intensive care unit care in both scene and transferred patients. An increase in ∆SI was predictive of the need for operative intervention ( p < 0.05). There were increased odds for mortality for every 0.1 change in EMSs SI; those changes were not deemed significant among both scene and transfer patients ( p < 0.1). CONCLUSION: Providers must maintain a high level of clinical suspicion for patients who had an initially elevated SI. Emergency medical services SI is a significant predictor for use of blood and intensive care unit care, as well as mortality for scene patients. This highlights the importance of SI and ∆SI in rural trauma care. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

Timing of venous thromboembolism prophylaxis initiation after injury: Findings from the consensus conference to implement optimal VTE prophylaxis in trauma.

ABSTRACT: Optimizing prophylaxis against venous thromboembolic events (VTEs) is a critical issue in the care of injured patients. Although these patients are at significant risk of developing VTE, they also present competing concerns related to exacerbation of bleeding from existing injuries. Especially after high-risk trauma, including injuries to the abdominal solid organs, brain, and spine, trauma providers must delineate the time period in which VTE prophylaxis successfully reduces VTE rates without encouraging bleeding. Although existing data are primarily retrospective in nature and further study is required, literature supports early VTE chemoprophylaxis initiation even for severely injured patients. Early initiation is most frequently defined as <48 hours from admission but varies from <24 hours to 72 hours and occasionally refers to time from initial trauma. Prior to chemical VTE prophylaxis initiation in patients at risk for bleeding, an observation period is necessary during which injuries must show themselves to be hemostatic, either clinically or radiographically. In the future, prospective examination of optimal timing of VTE prophylaxis is necessary. Further study of specific subsets of trauma patients will allow for development of effective VTE mitigation strategies based upon collective risks of VTE and hemorrhage progression.

A multicenter evaluation on the impact of non-therapeutic transfer in rural trauma.

INTRODUCTION: Trauma transfers are a common occurrence in rural areas, where critical access and lower-level trauma centers routinely transfer to tertiary care centers for specialized care. Transfers are non-therapeutic (NTT) when no specialist intervention occurs, leading to transfer that were futile (FT) or secondary overtriage (SOT). This study aimed to evaluate the prevalence of NTT among four trauma centers providing care to rural Appalachia. METHODS: This retrospective review was performed at four, ACS verified, Level 1 trauma centers. All adult trauma patients, transferred during 2018 were included for analysis. Transfers were considered futile if in <48 h the patient died or was discharged to hospice, without operative intervention. SOT transfers were discharged in <48 h, without major intervention, with an ISS< 15. Cost analysis was performed to describe the impact of NTT on EMS use. RESULTS: 4,189 patients were analyzed during the study period. 105 (2.5%) met criteria for futility. Futile patients had a median ISS of 25 (IQR 9-26), and 48% had an AIS head ≥4. These were significantly greater (p<0.001) than non-futile transfers, median ISS 5 (IQR 2-9), 3% severe head injury. SOT occurred in 1371 (33%), median ISS of 5, and lower AIS scores by region. Isolated facial injuries resulted in 165 transfers. 13% of FT+SOT were admitted to the ICU. Only 22% of FT+SOT came from a trauma center. 68% were transported by ALS and 13% transported by air transport. FT+SOT traveled on average 70 miles from their home to receive care. CONCLUSIONS: Non-therapeutic transfers account for more than 1/3 of transfers in this rural environment. There was a significant use of advanced life support and aeromedical transport. The utility of these transfers should be questioned. With the recent increases in telehealth there is an opportunity for trauma systems to improve regional care and decrease transfers for futile cases.

History of Equity, Diversity, and Inclusion in Trauma Surgery: for Our Patients, for Our Profession, and for Ourselves.

Purpose of Review: Disparities exist in outcome after injury, particularly related to race, ethnicity, socioeconomics, geography, and age. The mechanisms for this outcome disparity continue to be investigated. As trauma care providers, we are challenged to be mindful of and mitigate the impact of these disparities so that all patients realize the same opportunities for recovery. As surgeons, we also have varied professional experiences and opportunities for achievement and advancement depending upon our gender, ethnicity, race, religion, and sexual orientation. Even within a profession associated with relative affluence, socioeconomic status conveys different professional opportunities for surgeons. Recent Findings: Fortunately, the profession of trauma surgery has undergone significant progress in raising awareness of patient and professional inequity among trauma patients and surgeons and has implemented systematic changes to diminish these inequities. Herein we will discuss the history of equity and inclusion in trauma surgery as it has affected our patients, our profession, and our individual selves. Summary: Our goal is to provide a historical context, a status report, and a list of key initiatives or objectives on which all of us must focus. In doing so, the best possible clinical outcomes can be achieved for patients and the best professional and personal "outcomes" can be achieved for practicing and future trauma surgeons.

An analysis of police transport in an Eastern Association for the Surgery of Trauma multicenter trial examining prehospital procedures in penetrating trauma patients.

BACKGROUND: Police transport (PT) of penetrating trauma patients in urban locations has become routine in certain metropolitan areas; however, whether it results in improved outcomes over prehospital Advanced life support (ALS) transport has not been determined in a multicenter study. We hypothesized that PT would not result in improved outcomes. METHODS: This was a multicenter, prospective, observational study of adults (18+ years) with penetrating trauma to the torso and/or proximal extremity presenting at 25 urban trauma centers. Police transport and ALS patients were allocated via nearest neighbor, propensity matching. Transport mode also examined by Cox regression. RESULTS: Of 1,618 total patients, 294 (18.2%) had PT and 1,324 (81.8%) were by ALS. After matching, 588 (294/cohort) remained. The patients were primarily Black (n = 497, 84.5%), males (n = 525, 89.3%, injured by gunshot wound (n = 494, 84.0%) with 34.5% (n = 203) having Injury Severity Score of 16 or higher. Overall mortality by propensity matching was not different between cohorts (15.6% ALS vs. 15.0% PT, p = 0.82). In severely injured patients (Injury Severity Score ≥16), mortality did not differ between PT and ALS transport (38.8% vs. 36.0%, respectively; p = 0.68). Cox regression analysis controlled for relevant factors revealed no association with a mortality benefit in patients transported by ALS. CONCLUSION: Police transport of penetrating trauma patients in urban locations results in similar outcomes compared with ALS. Immediate transport to definitive trauma care should be emphasized in this patient population. LEVEL OF EVIDENCE: Prognostic and Epidemiologic; Level III.

Occupational vs. non-occupational equestrians: Differences in demographics and injury patterns.

INTRODUCTION: Nineteen million people participate in horseback riding activities in the US, and the horse industry employs more than 460,000 full-time workers. Emergency department data suggest young female amateurs and male professionals are most at risk of death from horse-related injuries. However, there has been no investigation into factors that may increase severe injury and mortality risk in these populations. This study investigates demographics and injury pattern differences between occupational and non-occupational horse-related injuries in the US. METHODS: The 2017 American College of Surgeons National Trauma Databank (ACS NTDB) was analyzed for horse-related injury using ICD 10 codes. Demographics, injury data, protective device use, and hospital procedures were analyzed. Occupational versus non-occupational injuries based on incident location (farm, sports, recreational, residential) were compared using ANOVA or Pearson's Chi-squared test. RESULTS: Of 3911 incidents, the most common injury mechanism was falling from the horse, but occupational and non-occupational farm injuries showed higher incidence of being struck by a horse. One-third required surgery. Upper extremity injuries were most common. Occupational injuries more often affected upper extremities of working age, minority males with commercial insurance. Non-occupational injuries most often affected heads of women at the extremes of age. Helmet use was higher in occupational, non-occupational sports, and non-occupational recreation injuries, and severe head injury incidence was decreased in these groups. Complications and discharge dispositions were not different across groups. CONCLUSIONS: In the largest trauma center study to date, we have shown equine-related trauma to be common and affect a predictable demographic that may permit injury prevention initiatives. Helmets may reduce severe head injury, but the efficacy of protective clothing remains to be validated.

Demonstration of a U.S. nationwide reduction in transfusion in general surgery and a review of published transfusion reduction methodologies.

BACKGROUND: Red blood cell transfusions in surgical procedures can be lifesaving. However, recent studies show transfusions are associated with a dose-dependent increase in postoperative morbidity and mortality; hospitals and physicians have attempted to reduce them. We sought to determine the success of these efforts and review and summarize published reduction methods employed. STUDY DESIGN/METHODS: An analysis of transfusion data from ACS-NSQIP public use files of general surgical procedures for 2012 and 2018; a retrospective review of the literature surrounding general surgical transfusion reduction from 2008 to 2018. RESULTS: The rate of general surgical transfusion in the NSQIP dataset decreased from 5.5% in 2012 to 4.0% in 2018, a 27% relative reduction in transfusion. After extensive multivariable adjustment for patient risk and operative complexity, this effect remained (Odds ratio 0.65, 95% CI 0.63-0.67, p < .001). Furthermore, there was a positive correlation between specific procedure decreases in transfusion and decreases in 30-day morbidity (rho =0.41, p = .003) and mortality (rho = 0.37, p = .007). There were 866 published studies matching our search term "red blood cell transfusion reduction." Forty-four were relevant to general surgery. Seven dominant strategies for transfusion reduction by descending frequency of report included restrictive transfusion thresholds, management of preoperative anemia, perioperative interventions, educational programs, electronic clinical decision support, waste reduction, and audits of transfusion practices. CONCLUSION: Our study demonstrates a 27% decrease in general surgery transfusion between 2012 and 2018 with associated reductions in morbidity and mortality, suggesting published employed strategies have been successful and safely implemented.

High Resource Utilization in Emergent Versus Elective General Surgery.

BACKGROUND: In an era of pay for performance metrics, we sought to increase understanding of factors driving high resource utilization (HRU) in emergent (EGS) versus same-day elective (SDGS) general surgery patients. METHODS: General surgery procedures from the 2016 ACS-NSQIP public use file were grouped according to the first four digits of the primary procedure CPT code. Groups having at least 100 of both elective and emergent cases were included (22 groups; 83,872 cases). HRU patients were defined as those in-hospital >7D, returned to the OR, readmitted, and/or had morbidity likely requiring an intensive care unit (ICU)stay. Independent NSQIP predictors of HRU were identified through forward regression; P for entry < 0.05, for exit > 0.10. RESULTS: Of all patients, 33% were HRU. The three highest HRU procedures (total colectomy, enterolysis, and ileostomy) comprised a higher proportion of EGS than SDGS cases (10.3 versus 2.6%, P < 0.001). The duration of operation was 40 Min lower in EGS after adjustment. Thirty-nine of the remaining 40 HRU predictors were higher in EGS including preoperative SIRS/Sepsis (50 versus 2%), ASA classification IV-V (31 versus 5%), albumin <3.5 g/dL (40 versus 12%), transfers (26 versus 2%, P's < 0.001), septuagenarians (35 versus 25%) and disseminated cancer (6.3 versus 4.8%, P's < 0.001); while sex did not differ. After adjustment, EGS patients remained more likely to be HRU (odds ratio 2.5, 95% CI 2.4 - 2.6, P < 0.001). CONCLUSIONS: EGS patients utilize significantly more resources than SDGS patients above what can be adjusted for in the clinically robust ACS-NSQIP dataset. Distinctive payment and value-based performance models are necessary for EGS.

The Influence of the Opioid Epidemic on Firearm Violence in Kentucky Counties.

BACKGROUND: The opioid crisis is a major public health emergency. Current data likely underestimate the full impact on mortality due to limitations in reporting and toxicology screening. We explored the relationship between opioid overdose and firearm-associated emergency department visits (ODED & FAED, respectively). METHODS: For the years 2010 to 2017, we analyzed county-level ODED and FAED visits in Kentucky using Office of Health Policy and US Census Bureau data. Firearm death certificate data were analyzed along with high-dose prescriptions from the Kentucky All Schedule Prescription Electronic Reporting records. Socioeconomic variables analyzed included health insurance coverage, race, median household earnings, unemployment rate, and high-school graduation rate. RESULTS: ODED and FAED visits were correlated (Rho = 0.29, P< 0.01) and both increased over the study period, remarkably so after 2013 (P < 0.001). FAED visits were higher in rural compared to metro counties (P < 0.001), while ODED visits were not. In multivariable analysis, FAED visits were associated with ODED visits (Std. B = 0.24, P= 0.001), high-dose prescriptions (0.21, P = 0.008), rural status (0.19, P = 0.012), percentage white race (-0.28, P = 0.012), and percentage high school graduates (-0.68, P < 0.001). Unemployment and earnings were bivariate correlates with FAED visits (Rho = 0.42, P < 0.001 and -0.32, P < 0.001, respectively) but were not significant in the multivariable model. CONCLUSIONS: In addition to recognized nonfatal consequences of the opioid crisis, firearm violence appears to be a corollary impact, particularly in rural counties. Firearm injury prevention efforts should consider the contribution of opioid use and abuse.

An Eastern Association for the Surgery of Trauma multicenter trial examining prehospital procedures in penetrating trauma patients.

BACKGROUND: Prehospital procedures (PHP) by emergency medical services (EMS) are performed regularly in penetrating trauma patients despite previous studies demonstrating no benefit. We sought to examine the influence of PHPs on outcomes in penetrating trauma patients in urban locations where transport to trauma center is not prolonged. We hypothesized that patients without PHPs would have better outcomes than those undergoing PHP. METHODS: This was an Eastern Association for the Surgery of Trauma-sponsored, multicenter, prospective, observational trial of adults (18+ years) with penetrating trauma to the torso and/or proximal extremity presenting at 25 urban trauma centers. The impact of PHPs and transport mechanism on in-hospital mortality were examined. RESULTS: Of 2,284 patients included, 1,386 (60.7%) underwent PHP. The patients were primarily Black (n = 1,527, 66.9%) males (n = 1,986, 87.5%) injured by gunshot wound (n = 1,510, 66.0%) with 34.1% (n = 726) having New Injury Severity Score of ≥16. A total of 1,427 patients (62.5%) were transported by Advanced Life Support EMS, 17.2% (n = 392) by private vehicle, 13.7% (n = 312) by police, and 6.7% (n = 153) by Basic Life Support EMS. Of the PHP patients, 69.1% received PHP on scene, 59.9% received PHP in route, and 29.0% received PHP both on scene and in route. Initial scene vitals differed between groups, but initial emergency department vitals did not. Receipt of ≥1 PHP increased mortality odds (odds ratio [OR], 1.36; 95% confidence interval [CI], 1.01-1.83; p = 0.04). Logistic regression showed increased mortality with each PHP, whether on scene or during transport. Subset analysis of specific PHP revealed that intubation (OR, 10.76; 95% CI, 4.02-28.78; p < 0.001), C-spine immobilization (OR, 5.80; 95% CI, 1.85-18.26; p < 0.01), and pleural decompression (OR, 3.70; 95% CI, 1.33-10.28; p = 0.01) had the highest odds of mortality after adjusting for multiple variables. CONCLUSION: Prehospital procedures in penetrating trauma patients impart no survival advantage and may be harmful in urban settings, even when performed during transport. Therefore, PHP should be forgone in lieu of immediate transport to improve patient outcomes. LEVEL OF EVIDENCE: Prognostic, level III.

Association of Prehospital Step 1 Vital Sign Criteria and Vital Sign Decline with Increased Emergency Department and Hospital Death.

BACKGROUND: This study analyzed data from the 2017 American College of Surgeons National Trauma Data Bank to examine the effects of pre-hospital Field Triage Decision Scheme Step 1 vital sign criteria (S1C) and vital sign decline on subsequent emergency department (ED) and hospital death in emergency medical services (EMS) transported trauma victims. STUDY DESIGN: Patient and injury characteristics, transport time, and ED and hospital disposition were collected. S1C (respiratory rate [RR]<10, RR>29 breaths/min, systolic blood pressure [SBP]<90 mmHg, Glasgow Coma Scale [GCS]<14) were recorded at the injury scene and hospital arrival. Decline was defined as a change ≥ 1 standard deviation (SD) into or within an S1C range. S1C and decline were analyzed relative to ED and hospital death using logistic regression. RESULTS: Of 333,213 included patients, 54,849 (16.5%) met Step 1 criteria at the scene, and 21,566 (6.9%) declined en route. The ED death rate was 0.4% (n = 1,188), and the hospital death/hospice rate was 4.0% (11,624 of 287,675). Patients who met S1C at the scene or who declined were more likely to require longer hospital lengths of stay, ICU admission, and surgical intervention. S1C and decline patients had higher odds of death in both the ED (S1C odds ratio [OR] 15.1, decline OR 2.4, p values < 0.001) and hospital (S1C OR 4.8, decline OR 2.0, p values < 0.001) after adjusting for patient demographics, transport time and mode, injury severity, and injury mechanism. Each S1C and decline measure was independently predictive of death. CONCLUSIONS: This study quantifies the mortality risks associated with individual S1C and validates their use as an indicator for injury severity and pre-hospital triage tool.

Intraoperative vasopressor use during emergency surgery on injured meth users.

BACKGROUND: Methamphetamine is a growing drug of abuse in America. Patients with recent methamphetamine use pose potential complications to general anesthesia due to changes in hemodynamics and arrhythmias. Limited data exists on the incidence of intraoperative complications on methamphetamine-intoxicated patients requiring urgent or emergent trauma surgery. This study aims to describe intraoperative complications observed in methamphetamine and amphetamine-intoxicated patients requiring emergent surgery. METHODS: Using the Trauma Registry at our ACS-verified level I trauma center, we completed a single-center, descriptive, retrospective cohort review between July 1, 2012 and June 30, 2016, of adult patients requiring emergent surgery with a positive urine-drug screen for methamphetamines or amphetamines. The objective was to evaluate vasopressor utilization during surgical operation. RESULTS: A total of 92 patients were identified with a positive UDS for amphetamine and/or methamphetamine who went to the operating room within 24 hours of admission. Thirty-two (34%) patients received one or more (≥1) doses of vasopressor, while 60 patients (66%) received no vasopressor. Changes in mean arterial pressure (MAP) were noted in 64%, while only 3% experienced an EKG change. A binomial logistic regression showed age, base deficit and change in MAP to be predictive of vasopressor use (p<0.002). No intraoperative cardiac events or anesthetic complications were seen. DISCUSSION: Hemodynamic instability in the amphetamine and methamphetamine-intoxicated population may be more directly related to degree of resuscitation required, than the presence of a positive UDS. LEVEL OF EVIDENCE: IV.

Perceptions of Equity and Inclusion in Acute Care Surgery: From the #EAST4ALL Survey.

OBJECTIVES AND BACKGROUND: The aim of this study was to characterize equity and inclusion in acute care surgery (ACS) with a survey to examine the demographics of ACS surgeons, the exclusionary or biased behaviors they witnessed and experienced, and where those behaviors happen. A major initiative of the Equity, Quality, and Inclusion in Trauma Surgery Practice Ad Hoc Task Force of the Eastern Association for the Surgery of Trauma was to characterize equity and inclusion in ACS. To do so, a survey was created with the above objectives. METHODS: A cross-sectional, mixed-methods anonymous online survey was sent to all EAST members. Closed-ended questions are reported as percentages with a cutoff of α = 0.05 for significance. Quantitative results were analyzed focusing on mistreatment and bias. RESULTS: Most respondents identified as white, non-Hispanic and male. In the past 12 months, 57.5% of females witnessed or experienced sexual harassment, whereas 48.6% of surgeons of color witnessed or experienced racial/ethnic discrimination. Sexual harassment, racial/ethnic prejudice, or discrimination based on sexual orientation/sex identity was more frequent in the workplace than at academic conferences or in ACS. Females were more likely than males to report unfair treatment due to age, appearance or sex in the workplace and ACS (P ≤ 0.002). Surgeons of color were more likely than white, non-Hispanics to report unfair treatment in the workplace and ACS due to race/ethnicity (P < 0.001). CONCLUSIONS: This is the first survey of ACS surgeons on equity and inclusion. Perceptions of bias are prevalent. Minorities reported more inequity than their white male counterparts. Behavior in the workplace was worse than at academic conferences or ACS. Ensuring equity and inclusion may help ACS attract and retain the best and brightest without fear of unfair treatment.
