Abstract
The reduction in the blood supply following the 2019 coronavirus pandemic has been exacerbated by the increased use of balanced resuscitation with blood components including whole blood in urban trauma centers. This reduction of the blood supply has diminished the ability of blood banks to maintain a constant supply to meet the demands associated with periodic surges of urban trauma resuscitation. This scarcity has highlighted the need for increased vigilance through blood product stewardship, particularly among severely bleeding trauma patients (SBTPs). This stewardship can be enhanced by the identification of reliable clinical and laboratory parameters which accurately indicate when massive transfusion is futile. Consequently, there has been a recent attempt to develop scoring systems in the prehospital and emergency department settings which include clinical, laboratory, and physiologic parameters and blood products per hour transfused as predictors of futile resuscitation. Defining futility in SBTPs, however, remains unclear, and there is only nascent literature which defines those criteria which reliably predict futility in SBTPs. The purpose of this review is to provide a focused examination of the literature in order to define reliable parameters of futility in SBTPs. The knowledge of these reliable parameters of futility may help define a foundation for drawing conclusions which will provide a clear roadmap for traumatologists when confronted with SBTPs who are candidates for the declaration of futility. Therefore, we systematically reviewed the literature regarding the definition of futile resuscitation for patients with trauma-induced hemorrhagic shock, and we propose a concise roadmap for clinicians to help them use well-defined clinical, laboratory, and viscoelastic parameters which can define futility.

Abstract
BACKGROUND Whether and how the transfusion volume should be limited in resuscitation after trauma remains unclear. We investigated the association between transfusion volume and survival outcome following trauma. METHODS Using the Japan Trauma Data Bank (2019-2021), we identified patients 18 years or older who received balanced blood transfusion within the first 24 hours of injury. We evaluated the association between the total number of red blood cell (RBC) units transfused and survival at discharge using logistic regression analysis and generalized additive model. Subgroup analyses based on patient characteristics were performed. RESULTS Overall, 5,123 patients from 165 hospitals were eligible for analysis. The transfusion volume was significantly associated with survival rate. Compared with that of patients receiving 4 to 9 RBC units, the within-hospital odds ratios (95% confidence interval) for survival at discharge were 0.62 (0.55-0.75), 0.32 (0.25-0.40), and 0.15 (0.12-0.20) for those receiving 10 to 19, 20 to 29, and ≥30 U, respectively. The probability of survival decreased consistently without any discernible threshold; however, the survival rates remained >40% and >20% even in patients receiving 50 and 80 RBC units, respectively. Significant interactions were observed between the number of RBC units transfused and each subgroup for survival at discharge. CONCLUSION The probability of survival consistently diminished as the transfusion volume increased. The absence of a threshold and lack of exceedingly low probability of survival support massive transfusion when clinicians perceive ongoing transfusion as beneficial. The unique context of each clinical situation must be considered in decision making. LEVEL OF EVIDENCE Therapeutic/Care Management; Level III.

Abstract
BACKGROUND Previous studies have shown improved survival for severely injured adult patients treated at American College of Surgeons verified level I/II trauma centers compared to level III and undesignated centers. However, this relationship has not been well established in pediatric trauma centers (PTCs). We hypothesize that severely injured children will have lower mortality at verified level I/II PTCs compared to centers without PTC verification. METHODS All patients 1-15 years of age with ISS >15 in the 2017-2019 American College of Surgeons Trauma Quality Programs (ACS TQP) dataset were reviewed. Patients with pre-hospital cardiac arrest, burns, and those transferred out for ongoing inpatient care were excluded. Logistic regression models were used to assess the effects of pediatric trauma center verification on mortality. RESULTS 16,301 patients were identified (64 % male, median ISS 21 [17-27]), and 60 % were admitted to verified PTCs. Overall mortality was 6.0 %. Mortality at centers with PTC verification was 5.1 % versus 7.3 % at centers without PTC verification (p < 0.001). After controlling for injury mechanism, sex, age, pediatric-adjusted shock index (SIPA), ISS, arrival via interhospital transfer, and adult trauma center verification, pediatric level I/II trauma center designation was independently associated with decreased mortality (OR 0.72, 95 % CI 0.61-0.85). CONCLUSIONS Treatment at ACS-verified pediatric trauma centers is associated with improved survival in critically injured children. These findings highlight the importance of PTC verification in optimizing outcomes for severely injured pediatric patients and should influence trauma center apportionment and prehospital triage.

Abstract
Background Despite the widespread use of ultra-massive transfusion (UMT) as an intervention for trauma patients in hemorrhagic shock, no standard definition exists. We performed a systematic review to determine a consensus definition for UMT. Methods A search was performed from 1979-2022. The authors screened studies defining UMT and associated outcomes as defined by our prespecified PICO questions. The PRISMA guidelines were used. Results 1662 articles met criteria for eligibility assessment, 17 for full-text review and eight for data extraction. Only two studies demonstrated a consensus definition of UMT, which used ≥20 units of red blood cell product within 24hrs. Parameters associated with increased mortality included lower blood pressure, lower pulse and lower Glasgow Coma Score at the time of presentation and a higher injury severity score and undergoing a resuscitative thoracotomy. Conclusions The absence of a consensus definition for UMT raises challenges from clinical, research and ethical perspectives. Based on our findings, the authors advocate for the feasibility of standardizing the definition of UMT as ≥20 units of red blood cell product within 24hrs.

Abstract
BACKGROUND Data on massive transfusion (MT) in geriatric trauma patients is lacking. This study aims to determine geriatric transfusion futility thresholds (TT) and TT variations based on frailty. METHODS Patients from 2013 to 2018 TQIP database receiving MT were stratified by age and frailty. TTs and outcomes were compared between geriatric and younger adults and among geriatric adults based on frailty status. RESULTS The TT was lower for geriatric than younger adults (34 vs 39 units; p = 0.03). There was no difference in TT between the non-frail, frail, and severely frail geriatric adults (37, 30 and 25 units, respectively, p > 0.05). Geriatric adults had higher mortality than younger adults (63.1% vs 45.8%, p < 0.01). Non-frail geriatric adults had the highest mortality (69.4% vs 56.5% vs 56.2%, p < 0.01). CONCLUSIONS Geriatric patients have a lower TT than younger adults, irrespective of frailty. This may help improve outcomes and optimize MT utilization.

Achieving balanced transfusion early in critically bleeding trauma patients: an observational study exploring the effect of attending trauma surgical presence during resuscitation.

Abstract
Background After 15 years of damage control resuscitation (DCR), studies still report high mortality rates for critically bleeding trauma patients. Adherence to massive hemorrhage protocols (MHPs) based on a 1:1:1 ratio of plasma, platelets, and red blood cells (RBCs) as part of DCR has been shown to improve outcomes. We wanted to assess MHP use in the early (6 hours from admission), critical phase of DCR and its impact on mortality. We hypothesized that the presence of an attending trauma surgeon during all MHP activations from 2013 would contribute to improving institutional resuscitation strategies and patient outcomes. Methods We conducted a retrospective analysis of all trauma patients receiving ≥10 RBCs within 6 hours of admission and included in the institutional trauma registry between 2009 and 2019. The cohort was divided in period 1 (P1): January 2009-August 2013, and period 2 (P2): September 2013-December 2019 for comparison of outcomes. Results A total of 141 patients were included, 81 in P1 and 60 in P2. Baseline characteristics were similar between the groups for Injury Severity Score, lactate, Glasgow Coma Scale, and base deficit. Patients in P2 received more plasma (16 units vs. 12 units; p<0.01), resulting in a more balanced plasma:RBC ratio (1.00 vs. 0.74; p<0.01), and platelets:RBC ratio (1.11 vs. 0.92; p<0.01). All-cause mortality rates decreased from P1 to P2, at 6 hours (22% to 8%; p=0.03), at 24 hours (36% vs 13%; p<0.01), and at 30 days (48% vs 30%, p=0.03), respectively. A stepwise logistic regression model predicted an OR of 0.27 (95% CI 0.08 to 0.93) for dying when admitted in P2. Conclusions Achieving balanced transfusion rates at 6 hours, facilitated by the presence of an attending trauma surgeon at all MHP activations, coincided with a reduction in all-cause mortality and hemorrhage-related deaths in massively transfused trauma patients at 6 hours, 24 hours, and 30 days.

Abstract
BACKGROUND Trauma networks have multiple designated levels of trauma care. This classification parallels concentration of major trauma care, creating innovations and improving outcome measures. OBJECTIVES The objective of this study is to assess associations of level of trauma care with patient outcomes for populations with specific severe injuries. METHODS A systematic literature search was conducted using six electronic databases up to April 19, 2022 (PROSPERO CRD42022327576). Studies comparing fatal, nonfatal clinical, or functional outcomes across different levels of trauma care for trauma populations with specific severe injuries or injured body region (Abbreviated Injury Scale score ≥3) were included. Two independent reviewers included studies, extracted data, and assessed quality. Unadjusted and adjusted pooled effect sizes were calculated with random-effects meta-analysis comparing Level I and Level II trauma centers. RESULTS Thirty-five studies (1,100,888 patients) were included, of which 25 studies (n = 443,095) used for meta-analysis, suggesting a survival benefit for the severely injured admitted to a Level I trauma center compared with a Level II trauma center (adjusted odds ratio [OR], 1.15; 95% confidence interval [CI], 1.06-1.25). Adjusted subgroup analysis on in-hospital mortality was done for patients with traumatic brain injuries (OR, 1.23; 95% CI, 1.01-1.50) and hemodynamically unstable patients (OR, 1.09; 95% CI, 0.98-1.22). Hospital and intensive care unit length of stay resulted in an unadjusted mean difference of -1.63 (95% CI, -2.89 to -0.36) and -0.21 (95% CI, -1.04 to 0.61), respectively, discharged home resulted in an unadjusted OR of 0.92 (95% CI, 0.78-1.09). CONCLUSION Severely injured patients admitted to a Level I trauma center have a survival benefit. Nonfatal outcomes were indicative for a longer stay, more intensive care, and more frequently posthospital recovery trajectories after being admitted to top levels of trauma care. Trauma networks with designated levels of trauma care are beneficial to the multidisciplinary character of trauma care. LEVEL OF EVIDENCE Systematic review and meta-analysis; Level III.

Abstract
INTRODUCTION Trauma systems continue to evolve to create the best outcomes possible for patients who have undergone traumatic injury. OBJECTIVE This review aims to evaluate the existing research on outcomes based on field triage to a Level 1 trauma center (L1TC) compared to other levels of hospitals and nontrauma centers. METHODS A structured literature search was conducted using PubMed, CINAHL, Embase, and the Cochrane Database. Studies analyzing measures of morbidity, mortality, and cost after receiving care at L1TCs compared to lower-level trauma centers and nontrauma centers in the United States and Canada were included. Three independent reviewers reviewed abstracts, and two independent reviewers conducted full-text review and quality assessment of the included articles. RESULTS Twelve thousand five hundred fourteen unique articles were identified using the literature search. 61 relevant studies were included in this scoping review. 95.2% of included studies were national or regional studies, and 96.8% were registry-based studies. 72.6% of included studies adjusted their results to account for injury severity. The findings from receiving trauma care at L1TCs vary depending on severity of injury, type of injury sustained, and patient characteristics. Existing literature suffers from limitations inherent to large de-identified databases, making record linkage between hospitals impossible. CONCLUSIONS This scoping review shows that the survival benefit of L1TC care is largest for patients with the most severe injuries. This scoping review demonstrates that further research using high-quality data is needed to elucidate more about how to structure trauma systems to improve outcomes for patients with different severities of injuries and in different types of facilities.

Abstract
INTRODUCTION Increased blood volumes, due to massive transfusion (MT), are known to be associated with both infectious and noninfectious adverse outcomes. The aim of this study was to assess the association between MT and outcomes in pediatric trauma patients, and, secondarily, determine if these outcomes are differential by age once MT is reached. METHODS Pediatric patients (ages 1-18 y old) in the ACS pediatric Trauma Quality Improvement Program (TQIP) database (2015-2018) who received blood were included. Patients were stratified by MT status, which was defined as blood product volume of 40 mL/kg within 24 h of admission (MT+) and compared to children who received blood products but did not meet the MT threshold (MT-). Defined MT + patients were matched 1:1 to MT-patients via propensity score matching of characteristics before comparisons. Adjusted logistic regression was performed on univariably significant outcomes of interest. RESULTS There were 2318 patients in the analytic cohort. Patients who received MT had higher rates of deep venous thrombosis (DVT) (2.5% versus 1.0%, P < 0.001), acute kidney injury (AKI) (1.5% versus 0.0%, P = 0.022), CLABSI (4.0% versus 2.0% P = 0.008), and severe sepsis (2.3% versus. 1.1%, P = 0.02). On logistic regression MT was an independent risk factor for these outcomes. There was no differential effect of MT on these outcomes based on age. CONCLUSIONS Outcomes associated with blood transfusion in pediatric trauma patients are low overall, but rates of DVT, AKI, CLABSI, and sepsis are higher in those who receive MT+ with no differences based on age.

Abstract
BACKGROUND Balanced transfusion is lifesaving for hemorrhagic shock. The American Red Cross critical blood shortage in 2022 threatened the immediate availability of blood. To eliminate waste, we reviewed the utility of transfusions per unit to define expected mortality at various levels of balanced transfusion. METHODS A retrospective study of 296 patients receiving massive transfusion on presentation at a level 1 trauma center was performed from January 2018 to December 2021. Units of packed red blood cells (PRBCs), fresh frozen plasma (FFP), and platelets received in the first 4 hours were recorded. Patients were excluded if they died in the emergency department, died on arrival, received <2 U PRBCs or FFP, or received PRBC/FFP >2:1. Primary outcomes were mortality and odds of survival to discharge. Subgroups were defined as transfused if receiving 2 to 9 U PRBCs, massive transfusion for 10 to 19 U PRBCs, and ultramassive transfusion for ≥20 U PRBCs. RESULTS A total of 207 patients were included (median age, 32 years; median Injury Severity Score, 25; 67% with penetrating mechanism). Mortality was 29% (61 of 207 patients). Odds of survival is equal to odds of mortality at 11 U PRBCs (odds ratio [OR], 0.95; 95% confidence interval [CI], 0.50-1.79). Beyond 16 U PRBCs, odds of mortality exceed survival (OR, 0.36; 95% CI, 0.16-0.82). Survival approaches zero >36 U PRBCs (OR, 0.09; 95% CI, 0.00-0.56). Subgroup mortality rates increased with unit transfused (16% transfused vs. 36% massive transfusion, p = 0.003; 36% massive transfusion vs. 67% ultramassive transfusion, p = 0.006). CONCLUSION Mortality increases with each unit balanced transfusion. Surgeons should view efforts heroic beyond 16 U PRBCs/4 hours and near futile beyond 36 U PRBCs/4 hours. While extreme outliers can survive, consider cessation of resuscitation beyond 36 U PRBCs. This is especially true if hemostasis has not been achieved or blood supplies are limited. LEVEL OF EVIDENCE Prognostic and Epidemiologic; Level IV.

Abstract
BACKGROUND Treating older trauma patients requires a focus on the confluence of age-related physiological changes and the impact of the injury itself. Therefore, the primary way to improve the care of geriatric trauma patients is through the development of universal, systematic multidisciplinary research. To achieve this, the Coalition for National Trauma Research has developed the National Trauma Research Action Plan that has generated a comprehensive research agenda spanning the continuum of geriatric trauma care from prehospital to rehabilitation. METHODS Experts in geriatric trauma care and research were recruited to identify current gaps in clinical geriatric research, generate research questions, and establish the priority of these questions using a consensus-driven Delphi survey approach. Participants were identified using established Delphi recruitment guidelines ensuring heterogeneity and generalizability. On subsequent surveys, participants were asked to rank the priority of each research question on a nine-point Likert scale, categorized to represent low-, medium-, and high-priority items. The consensus was defined as more than 60% of panelists agreeing on the priority category. RESULTS A total of 24 subject matter experts generated questions in 109 key topic areas. After editing for duplication, 514 questions were included in the priority ranking. By round 3, 362 questions (70%) reached 60% consensus. Of these, 161 (44%) were high, 198 (55%) medium, and 3 (1%) low priority. CONCLUSION Among the questions prioritized as high priority, questions related to three types of injuries (i.e., rib fracture, traumatic brain injury, and lower extremity injury) occurred with the greatest frequency. Among the 25 highest priority questions, the key topics with the highest frequency were pain management, frailty, and anticoagulation-related interventions. The most common types of research proposed were interventional clinical trials and comparative effectiveness studies, outcome research, and health care systems research.

Abstract
Objective: Improving the care of injuries resulting from terrorist attacks requires understanding injury mechanisms in armed conflicts. The aim of this study was to identify injury characteristics in military personnel with thoracoabdominal combat injuries resulting from terrorist attacks in urban settings.
Material and Methods: A retrospective study of military personnel with thoracoabdominal injuries who were referred to a tertiary center after treating and stabilizing at a primary healthcare organization due to terror-related injuries in various urban regions of Turkey between June 2015 and December 2016 was performed.
Results: A total of 70 patients were included in this study, of whom 87.1% were injured by explosives and 12.9% (n= 9) had gunshot wounds (GSWs). Mean injury severity score (ISS) was 21, blood transfusion amount was 3.7 units, and mortality rate was 8.5%. Patients injured by explosives had most commonly abdominal and extremity injuries (31.1%), whereas isolated abdominal injuries (55.6%) were observed among patients with GSWs. There were no significant differences between the mechanisms of injuries and the ISS, blood transfusion, and mortality (p= 0.635, p= 0.634, and p= 0.770, respectively). A significant correlation was observed between the ISS and transfusion amounts (r= 0.548, p< 0.001). Mortality was significantly higher in those with a high ISS and those undergoing massive blood transfusions (p= 0.004 and p< 0.001, respectively).
Conclusion: Explosive injuries, concomitant vascular injuries, high ISS, and the need for massive transfusions increased the mortality rate in urban combat injuries. To quickly identify high-risk patients and improve the care of injuries, it is essential to use predictive models or scoring systems.

Abstract
Objectives Integrate a predictive model for massive transfusion protocol (MTP) activation and delivery in the electronic medical record (EMR) using prospectively gathered data; externally validate the model and assess the accuracy and precision of the model over time. Background The Emory model for predicting MTP using only four input variables was chosen to be integrated into our hospital's EMR to provide a real time clinical decision support tool. The continuous variable output allows for periodic re-calibration of the model to optimize sensitivity and specificity. Methods Prospectively collected data from level 1 and 2 trauma activations were used to input heart rate, systolic blood pressure, base excess (BE) and mechanism of injury into the EMR-integrated model for predicting MTP activation and delivery. MTP delivery was defined as: 6 units of packed red blood cells/6 hours (MTP1) or 10 units in 24 hours (MTP2). The probability of MTP was reported in the EMR. ROC and PR curves were constructed at 6, 12, and 20 months to assess the adequacy of the model. Results Data from 1162 patients were included. Areas under ROC for MTP activation, MTP1 and MTP2 delivery at 6, 12, and 20 months were 0.800, 0.821, and 0.831; 0.796, 0.861, and 0.879; and 0.809, 0.875, and 0.905 (all P < 0.001). The areas under the PR curves also improved, reaching values at 20 months of 0.371, 0.339, and 0.355 for MTP activation, MTP1 delivery, and MTP2 delivery. Conclusions A predictive model for MTP activation and delivery was integrated into our EMR using prospectively collected data to externally validate the model. The model's performance improved over time. The ability to choose the cut-points of the ROC and PR curves due to the continuous variable output of probability of MTP allows one to optimize sensitivity or specificity.

Abstract
BACKGROUND: Patients with uncontrolled blood loss often require immediate blood transfusion after the bleeding is stopped. If it is an emergency situation, blood that has not been tested for compatibility (uncrossmatched red blood cell [URBC] products) can be used. However, no studies have been conducted to evaluate the effectiveness of this protocol.
AIM: The aim of the study is to evaluate the effectiveness of URBC transfusion in Srinagarind Hospital’s emergency department (ED).
METHODS: This was a cross-sectional study that reviewed the medical records of ninty Thai patients over 18 years of age who received at least one unit of blood through URBC transfusion in the Srinagarind Hospital ED from September 2016 to August 2018.
RESULTS: The average age of the patients was 47.23 ± 18.2 years, and 73.3% were male. A total of 149 units of URBC were provided, with 54.44% of recipients being trauma patients and 27.78% being gastrointestinal bleeding patients. The 24-h and in-hospital mortality rates were 58.89 and 72.22%, respectively. There were no cases of acute blood transfusion complications or inappropriate URBC transfusion.
CONCLUSIONS: The transfusion of URBC necessary in patients with uncontrolled bleeding. No complications were found due to acute blood transfusion.

Abstract
BACKGROUND The use of whole blood (WB) for the treatment of hemorrhagic shock and coagulopathy is increasing in civilian trauma patients. Four-factor prothrombin complex concentrate (4-PCC) in adjunct to component therapy showed improved outcomes in trauma patients. Our study aims to evaluate the outcomes of trauma patients who received 4-PCC and WB (4-PCC-WB) compared with WB alone. METHODS We performed a 3-year (2015-2017) analysis of the American College of Surgeons-Trauma Quality Improvement Program database. All adult (age, ≥18 years) trauma patients who received WB were included. We excluded patients who were on preinjury anticoagulants. Patients were stratified into two groups, 4-PCC-WB versus WB alone, and matched in a 1:2 ratio using propensity score matching. Outcome measures were packed red blood cells, plasma, platelets, and cryoprecipitate transfused, in-hospital complications, hospital and intensive care unit (ICU) length of stay (LOS) among survivors, and mortality. RESULTS A total of 252 patients (4-PCC-WB, 84; WB alone, 168) were matched. The mean ± SD age was 47 ± 21 years, 63% were males, median Injury Severity Score was 30 (21-40), and 87% had blunt injuries. Patients who received 4-PCC-WB had decreased requirement for packed red blood cell (8 U vs. 10 U, p = 0.04) and fresh frozen plasma (6 U vs. 8 U, p = 0.01) transfusion, lower rates of acute kidney injury (p = 0.03), and ICU LOS (5 days vs. 8 days, p = 0.01) compared with WB alone. There was no difference in the platelet transfusion (p = 0.19), cryoprecipitate transfusion (p = 0.37), hospital LOS (p = 0.72), and in-hospital mortality (p = 0.72) between the two groups. CONCLUSION Our study demonstrates that the use of 4-PCC as an adjunct to WB is associated with a reduction in transfusion requirements and ICU LOS compared with WB alone in the resuscitation of trauma patients. Further studies are required to evaluate the role of PCC with WB in the resuscitation of trauma patients. LEVEL OF EVIDENCE Therapeutic, level III.

Abstract
PURPOSE To describe shock severity, physiological stabilization and organ failure in healthy women admitted to the intensive care unit (ICU) after major peripartum hemorrhage (PPH). MATERIALS AND METHODS Retrospective, descriptive, single center study. RESULTS Twenty-nine women median age 33 years (interquartile range [IQR] 30-36) and gravidity 5 pregnancies (IQR 3-9) were studied. One woman died. The median maternal admission hematocrit was 28.8 (IQR 25.7-32.4). Median transfusion rates were nine units of packed red blood cells (IQR 7-12.25), eight fresh frozen plasma (IQR 6-12), 17 platelets (IQR 10-22) and 15 cryoprecipitate (IQR 9.75-20). Blood pressure dropped significantly in the six hours following ICU admission. Nonetheless, lactate decreased from 3.23 mmol/L to 1.54 mmol/L within 24 h of ICU admission, renal and pulmonary function were unaffected and coagulopathy was never observed. Two-thirds of the women underwent hysterectomy. One-third underwent repeated surgery. The median length of ICU stay was <48 h and that of mechanical ventilation was <24 h. Increased transfusion rates correlated with lengthier ICU admission (p ≤ 0.01 regardless of blood product). CONCLUSIONS Ongoing hemorrhage in women with severe PPH manifests subtly and often requires active intervention. Hemorrhage control is required to achieve physiological stabilization and minimize organ damage.

Abstract
Introduction: Uncontrolled hemorrhage with trauma-induced coagulopathy (TIC) still represents the most common cause of preventable death after trauma. Timely diagnosis and treatment including bleeding control and hemostatic resuscitation to correct TIC are important, as death from exsanguination occurs rapidly. Recognizing who requires an early massive transfusion together with the initiation of corresponding massive transfusion protocols (MTPs) is key to outcome.Areas covered: This expert review summarizes the current state of MT including the activation and termination of MTPs, complications of MT, and strategies for refinement in the administration of blood products in order to avoid harmful over-transfusion.Expert opinion: MTPs should be initiated and continued until normal physiologic parameters are reached and definitive control of bleeding is achieved. Hospitals should develop their own MTPs, guided by evidence, and according to local infrastructure, logistics, needs and patient populations. Massive transfusion, defined as > 10 units of packed red blood cell concentrates (pRBCs) within the first 24 hours of hospital admission, can be life-saving, but is not without complications. MTPs are currently being refined through targeted and early goal-directed approaches which include functional coagulation testing assays to better guide the administration of blood products and hemostatic agents once the patient is stabilized.

Abstract
BACKGROUND The aim of this study was to assess the prognostic value of massive transfusion (MT), critical administration threshold (CAT), and resuscitation intensity (RI) for the mortality of trauma patients with severe hemorrhage. METHODS Seventeen relevant articles were obtained by searching the PubMed databases through February 15, 2019. The estimated mortality rates and injury severity scores were obtained through a meta-analysis. In addition, diagnostic test accuracy (DTA) reviews were conducted to obtain the sensitivity, specificity, diagnostic odds ratio, and the summary receiver operating characteristic curve. RESULTS At 24 hours, the estimated mortality rates were 0.194, 0.126, and 0.168 in assessments using MT, CAT, and RI, respectively. In addition, the pooled sensitivity of CAT (0.89; 95% confidence interval [CI], 0.82-0.94) was significantly higher than that of MT (0.63; 95% CI, 0.57-0.68) and RI (0.69; 95% CI, 0.63-0.75). Overall, the pooled specificity of MT and CAT was 0.82 (95% CI, 0.80-0.83) and 0.85 (95% CI, 0.83-0.88), respectively, while the pooled sensitivity was 0.49 (95% CI, 0.44-0.54) and 0.50 (95% CI, 0.38-0.62), respectively. CONCLUSION CAT may be a more sensitive predictor for 24-hour mortality than other predictors. Furthermore, RI also appears to be a useful predictor for 24-hour mortality. Both MT and CAT showed high specificity for overall mortality.

Patients with gunshot wounds to the torso differ in risk of mortality depending on treating hospital. Updates Surg 2019; 71:561-567.

Abstract
Previous studies have had conflicting results when comparing risk of mortality in patients with gunshot wounds (GSWs) treated at Level-I and II trauma centers. However, the populations studied were restricted geographically. We hypothesized that patients presenting after a GSW to the torso at Level-I centers would have a shorter time to surgical intervention (exploratory laparotomy or thoracotomy) and a lower risk of mortality, compared to Level-IIs in a national database. The Trauma Quality Improvement Program (2010-2016) was queried for patients presenting to Level-I or II trauma center after a GSW to the torso. A multivariable logistic regression analysis was performed. From 17,965 patients with GSWs, 13,812 (76.8%) were treated at Level-Is and 4153 (23.2%) at Level-IIs. There was no difference in the injury severity score (ISS) (p = 0.55). The Level-I cohort had a higher rate of laparotomy (38.9% vs. 36.5%, p < 0.001) with a shorter median time to laparotomy (49 vs. 55 min, p < 0.001) but no difference in rate (p = 0.14) and time to thoracotomy (p = 0.62). After adjusting for covariates, only patients undergoing thoracotomy (OR = 0.66, CI = 0.47-0.95, p = 0.02) or those undergoing non-operative management (NOM) (OR = 0.85, CI = 0.74-0.98, p = 0.03) at a Level-I center had lower risk for death, compared to Level-II. Patients with torso GSWs managed with thoracotomy or NOM at a Level-I center have a lower risk of mortality, compared to a Level-II. Future prospective studies examining variations in practice, resources available and surgeon experience to account for these differences are warranted.
