Geriatric trauma triage: optimizing systems for older adults-a publication of the American Association for the Surgery of Trauma Geriatric Trauma Committee.

Background: Geriatric trauma patients are an increasing population of the United States (US), sustaining a high incidence of falls, and suffer greater morbidity and mortality to their younger counterparts. Significant variation and challenges exist to optimize outcomes for this cohort, while being mindful of available resources. This manuscript provides concise summary of locoregional and national practices, including relevant updates in the triage of geriatric trauma in an effort to synthesize the results and provide guidance for further investigation. Methods: We conducted a review of geriatric triage in the United States (US) at multiple stages in the care of the older patient, evaluating existing literature and guidelines. Opportunities for improvement or standardization were identified. Results: Opportunities for improved geriatric trauma triage exist in the pre-hospital setting, in the trauma bay, and continue after admission. They may include physiologic criteria, biochemical markers, radiologic criteria and even age. Recent Trauma Quality Improvement Program (TQIP) Best Practices Guidelines for Geriatric Trauma Management published in 2024 support these findings. Conclusion: Trauma systems must adjust to provide optimal care for older adults. Further investigation is required to provide pertinent guidance.

Feeble, fallen, and forgetting: association of cognitive impairment and falls on outcomes of major intra-abdominal surgeries in older adults.

BACKGROUND: Both cognitive impairment/dementia (CID) and falls occur more commonly in older adults than in younger patients. This study aimed to analyze the association of a history of CID or falls with the postoperative outcomes of older adults undergoing major intra-abdominal surgeries on a national level. METHODS: We retrospectively analyzed the American College of Surgeons-National Surgical Quality Improvement Program 2022 Participant Use Data File. Our primary outcome was postoperative mortality. Statistical analysis was performed using the Chi-square test and multivariate regression analysis. RESULTS: On multivariable regression analyses, a history of both CID (odds ratio [OR] = 1.9; CI: 1.5-2.5; P < .01) and a fall (OR = 1.8; CI: 1.4-2.3; P < .01) were independently associated with higher adjusted odds of mortality. History of CID or falls was also a predictor of overall complications, major complications, and discharge to a care facility. CONCLUSION: A history of CID or falls in older adults before major intra-abdominal surgeries was associated with a high risk of postoperative mortality and morbidity. Further studies are required to establish the causal relation of these factors and the steps to mitigate the risk of associated adverse outcomes.

Interactive Media-Based Approach for an Exception From Informed Consent Trial Involving Patients With Trauma.

Importance: Exception From Informed Consent (EFIC) research requires community consultation (CC) and public disclosure (PD). Traditional methods of conducting CC and PD are slow, expensive, and labor intensive. Objective: To describe the feasibility and reach of a novel interactive, media-based approach to CC and PD and to identify the similarities and differences between trial sites in website views, survey responses, online community forum attendance, and opt-out requests. Design, Setting, and Participants: This survey study analyzed the CC and PD campaigns conducted for the TAP trial (Evaluation of BE1116 in Patients With Traumatic Injury and Acute Major Bleeding to Improve Survival), an EFIC trial of the early administration of prothrombin complex concentrate in patients with trauma. The CC and PD campaigns consisted of social media advertisements, linked websites, community surveys, and online community forums. These activities were coordinated from a central site and approved by a central institutional review board. This study focused on the first 52 of 91 TAP trial sites (level I trauma centers) in the US to have completed their CC and PD campaigns. Community members in the catchment areas of the participating trauma centers were targeted. Data analysis was conducted between October 2023 and February 2024. Exposure: Social media advertisements, surveys, and online community meetings conducted as part of the CC and PD campaign for the TAP trial. Main Outcomes and Measures: Social media campaign reach and engagement, web page views, survey results, online community forum attendance, and opt-out requests. Results: Fifty-two trial sites were approved for participant enrollment. Social media advertisements were displayed 92 million times, reaching 11.8 million individuals. The median (IQR) number of people reached in each location was 210 317 (172 068-276 968). Site-specific websites were viewed 144 197 times (median [IQR] viewings per site, 2984 [1267-4038]). A total of 17 206 fully or partly completed surveys were received, and survey respondents had a median (IQR) age of 40.1 (15-65) years and included 10 444 females (60.7%). Overall, 60.6% survey respondents said they would want to be entered into the trial even if they could not give consent, 87.7% agreed that emergency care research was necessary, and 88.0% agreed that the TAP trial should be conducted in their community. Online community forums were attended by a median (IQR) number of 38 (20-63) people. Four opt-out requests were received. Conclusions and Relevance: The interactive media-based approach to CC and PD for the ongoing TAP trial showed the feasibility and benefits of executing an efficient, coordinated, centrally run series of locally branded and geographically targeted CC and PD campaigns for a large EFIC study.

Early Glasgow Coma Scale Score and Prediction of Traumatic Brain Injury: A Secondary Analysis of Three Harmonized Prehospital Randomized Clinical Trials.

OBJECTIVES: The prehospital prediction of the radiographic diagnosis of traumatic brain injury (TBI) in hemorrhagic shock patients has the potential to promote early therapeutic interventions. However, the identification of TBI is often challenging and prehospital tools remain limited. While the Glasgow Coma Scale (GCS) score is frequently used to assess the extent of impaired consciousness after injury, the utility of the GCS scores in the early prehospital phase of care to predict TBI in patients with severe injury and concomitant shock is poorly understood.METHODS: We performed a post-hoc, secondary analysis utilizing data derived from three randomized prehospital clinical trials: the Prehospital Air Medical Plasma trial (PAMPER), the Study of Tranexamic Acid During Air Medical and Ground Prehospital Transport trial (STAAMP), and the Pragmatic Prehospital Type O Whole Blood Early Resuscitation (PPOWER) trial. Patients were dichotomized into two cohorts based on the presence of TBI and then further stratified into three groups based on prehospital GCS score: GCS 3, GCS 4-12, and GCS 13-15. The association between prehospital GCS score and clinical documentation of TBI was assessed.RESULTS: A total of 1,490 enrolled patients were included in this analysis. The percentage of patients with documented TBI in those with a GCS 3 was 59.5%, 42.4% in those with a GCS 4-12, and 11.8% in those with a GCS 13-15. The positive predictive value (PPV) of the prehospital GCS score for the diagnosis of TBI is low, with a GCS of 3 having only a 60% PPV. Hypotension and prehospital intubation are independent predictors of a low prehospital GCS. Decreasing prehospital GCS is strongly associated with higher incidence or mortality over time, irrespective of the diagnosis of TBI.CONCLUSIONS: The ability to accurately predict the presence of TBI in the prehospital phase of care is essential. The utility of the GCS scores in the early prehospital phase of care to predict TBI in patients with severe injury and concomitant shock is limited. The use of novel scoring systems and improved technology are needed to promote the accurate early diagnosis of TBI.

Final Lifelines: The Implications and Outcomes of Thoracic Damage Control Surgeries.

INTRODUCTION: There is a lack of data on the outcomes of thoracic damage control surgery (TDCS). This study aimed to describe the characteristics and outcomes of patients undergoing TDCS. METHODS: This is a retrospective analysis of the American College of Surgeons-Trauma Quality Improvement Program database (2017-2021). All trauma patients who underwent emergency thoracotomy and packing with temporary closure were included. Patients were stratified based on the age groups (pediatric [<18 y], adults [18-64 y], and older adults [≥65 y]). Our primary outcome measures included 6-h, 24-h, and in-hospital mortality. Secondary outcomes were major complications. RESULTS: We identified 14,192 thoracotomies, out of which 213 underwent TDCS (pediatric [n = 17], adults [n = 175], and older adults [n = 21]). The mean (SD) age was 37 (18), and 86% were male. The mean shock index was 1.1 (0.4) on presentation with a median [IQR] Glasgow Coma Scale of 4 [3-14], and 22.1% had a prehospital cardiac arrest. The study population was profoundly injured with a median injury severity scoreand chest-abbreviated injury scale of 26 [17-38] and 4 [3-5], respectively, with lung (76.5%) being the most injured intrathoracic organs. Overall, the rates of 6-h, 24-h, and in-hospital mortality were 22.5%, 33%, and 53%, respectively, and 51% developed major complications. There was no significant difference in terms of in-hospital mortality (P = 0.800) and major complications (0.416) among pediatrics, adults, and older adults. CONCLUSIONS: One in three patients undergoing TDCS die within the first 24 h, and more than half of them develop major complications and die in the hospital, with no difference among pediatric, adults, and older adults. Future efforts should be directed to improve the survival of these severely injured, metabolically depleted, challenging patients.

Less is More: Dissecting Trauma Centers by Procedural Volume.

OBJECTIVE: This study aims to examine the relationship between procedural volume and annual trauma volume (ATV) of ACS Level I trauma centers (TC). SUMMARY BACKGROUND DATA: Although ATV is a hard criterion for TC verification, importance of procedural interventions as a potential quality indicator is understudied. METHODS: Patients managed at ACS level I TCs were identified from ACS-TQIP 2017-2021. TCs were identified using facility keys and stratified into quartiles based on ATV into low, low-medium, medium-high, and high volume. TCs were also stratified into tertiles (low [LV], medium [MV], high [HV]) based on procedural volume by assessing annual number of laparotomies, thoracotomies, craniotomies/craniectomies, angioembolizations, vascular repairs, and long bone fixations performed at each center. Cohen's κ statistic was used to assess concordance between ATV and procedural volume. RESULTS: 182 Level I TCs were identified: 76 low, 47 low-medium, 35 high-medium, and 24 high volume. Long bone fixation, laparotomy, and craniotomy/craniectomy were the most performed procedures with a median of 65, 59, and 46 cases/center/year respectively. 31% of HV laparotomy centers, 31% of HV thoracotomy centers, 22% of HV craniotomy/craniectomy centers, 22% of HV vascular repair centers, 32% of HV long bone fixation centers, and 33% of HV angioembolization centers contributed to the overall number of low-medium and low volume TCs. Cohen's κ statistic demonstrated poor concordance between ATV and procedural volumes for all procedures (Overall procedural volume-κ=0.378, laparotomy-κ=0.270, thoracotomy-κ=0.202, craniotomy/craniectomy- κ=0.394, vascular repair-κ=0.298, long bone fixation-κ=0.277, angioembolization-κ=0.286). CONCLUSION: ATV does not reflect the procedural interventions performed. Combination of procedural and ATV may provide a more accurate picture of the clinical experience at any given TC. LEVEL OF EVIDENCE: Level III.

Finding The Sweet Spot: The Association Between Whole Blood to Red Blood Cells Ratio and Outcomes of Hemorrhaging Civilian Trauma Patients.

PURPOSE: To evaluate the dose-dependent effect of Whole Blood (WB) on the outcomes of civilian trauma patients with hemorrhagic shock. METHODS: We performed a 2-year (2020-2021) retrospective analysis of the ACS-TQIP dataset. Adult (≥18) trauma patients with a shock index (SI) >1 who received at least 5 units of PRBC and one unit of WB within the first 4 hours of admission were included. Primary outcomes were 6-hr, 24-hr, and in-hospital mortality. Secondary outcomes were major complications and hospital and ICU length of stay (LOS). RESULTS: A total of 830 trauma patients with a mean (SD) age of 38 (16) were identified. The median [IQR] 4-hour WB and PRBC requirements were 2[2-4] U and 10[7-15] U, respectively, with a median WB:RBC ratio of 0.2 [0.1-0.3]. Every 0.1 increase in WB:RBC ratio was associated with decreased odds of 24-hour mortality (aOR:0.916, p = 0.035) and in-hospital mortality (aOR:0.878, p < 0.001). Youden's index identified 0.25 (1 U of WB for every 4 U of PRBC) as the optimal WB:PRBC ratio to reduce 24-hour mortality. High ratio (≥0.25) group had lower adjusted odds of 24-hour mortality (aOR:0.678, p = 0.021) and in-hospital mortality (aOR:0.618, p < 0.001) compared to the Low ratio group. CONCLUSIONS: A higher WB:PRBC ratio was associated with improved early and late mortality in trauma patients with hemorrhagic shock. Given the availability of WB in trauma centers across the United States, at least one unit of WB for every four units of PRBC may be administered to improve the survival of hemorrhaging civilian trauma patients.

Characterization of adverse events in injured patients at risk of hemorrhagic shock: a secondary analysis of three harmonized prehospital randomized clinical trials.

Background: The reporting of adverse events (AEs) is required and well defined in the execution of clinical trials, but is poorly characterized particularly in prehospital trials focusing on traumatic injury. In the setting of prehospital traumatic injury trials, no literature currently exists analyzing the clinical implications of AEs and their associations with mortality and morbidity. We sought to analyze AEs from three prehospital hemorrhagic shock trials and characterize their time course, incidence, severity, associated clinical outcomes, and relatedness. Methods: We performed a secondary analysis of three prehospital randomized clinical trials. We analyzed AEs at both the patient level as well as the individual AE level. We categorized patients who had no AEs, a single documented AE and those with multiple events (>1 AE). We characterized AE timing, severity, relatedness and attributable mortality outcomes. Results: We included 1490 patients from the three harmonized clinical trials, with 299 (20.1%) individual patients having at least a single AE documented with 529 AEs documented overall as a proportion of patients had multiple events. Over 44% of patients had a death-related misclassified AE. Patients with at least a single documented AE had a significantly higher 28-day mortality (log-rank χ2=81.27, p<0.001) compared with those without an AE documented. Patients with a single AE had a significant higher mortality than those with multiple AEs, potentially due to survival bias (log-rank χ2=11.80, p=0.006). When relatedness of each individual AE was characterized, over 97% of AEs were classified as 'definitely not related' or 'probably not related' to the intervention. Conclusions: AEs in hemorrhagic shock trials are common, occur early and are associated with mortality and survival bias. The potential for inaccurate reporting exists, and education and training remain essential for appropriate treatment arm comparison. The current results have important relevance to injury-related clinical trials. Trial registration numbers: NCT01818427, NCT02086500 and NCT03477006. Level of evidence: II.

Drugs, Delirium, and Trauma: Substance Use and Incidence of Delirium After Traumatic Brain Injury.

INTRODUCTION: There is a paucity of data on the effect of preinjury substance (alcohol, drugs) abuse on the risk of delirium in patients with traumatic brain injury (TBI). This study aimed to assess the incidence of delirium among patients with blunt TBI in association with different substances. METHODS: We analyzed the 2020 American College of Surgeons-Trauma Quality Improvement Program. We included all adult (≥18 y) patients with blunt TBI who had a recorded substance (drugs and alcohol) screening. Our primary outcome was the incidence of delirium. RESULTS: A total of 72,901 blunt TBI patients were identified. The mean (standard deviation) age was 56 (20) years and 68.0% were males. The median (interquartile range) injury severity score was 17 (10-25). Among the study population, 23.1% tested positive for drugs (Stimulants: 3.0%; Depressants: 2.9%, hallucinogens: 5.1%, Cannabinoids: 13.4%, TCAs: 0.1%), and 22.8% tested positive for Alcohol. Overall, 1856 (2.5%) experienced delirium. On univariate analysis, patients who developed delirium were more likely to have positive drug screening results. On multivariable regression analyses, positive screen tests for isolated stimulants (adjusted odds ratio [aOR]: 1.340, P = 0.018), tricyclic antidepressants (aOR: 3.107, P = 0.019), and cannabinoids (aOR: 1.326, P ≤ 0.001) were independently associated with higher odds of developing delirium. CONCLUSIONS: Nearly one-fourth of adult patients with blunt TBI had an initial positive substance screening test. Patients with positive results for isolated stimulants, tricyclic antidepressants, and cannabinoids were at a higher risk of developing delirium, whereas this association was not evident with other drugs and alcohol-positive tests. These findings emphasize the need for early drug screening in TBI patients and close monitoring of patients with positive screening tests.

A comparison of outcomes including bile duct injury of subtotal cholecystectomy versus open total cholecystectomy as bailout procedures for severe cholecystitis: A multicenter real-world study.

BACKGROUND: Dense inflammation obscuring the hepatocystic anatomy can hinder the ability to perform a safe standard laparoscopic cholecystectomy in severe cholecystitis, requiring use of a bailout procedure. We compared clinical outcomes of laparoscopic and open subtotal cholecystectomy against the traditional standard of open total cholecystectomy to identify the optimal bailout strategy for the difficult gallbladder. METHODS: A multicenter, multinational retrospective cohort study of patients who underwent bailout procedures for severe cholecystitis. Procedures were compared using one-way analysis of variance/Kruskal-Wallis tests and χ2 tests with multiple pairwise comparisons, maintaining a family-wise error rate at 0.05. Multiple multivariate linear/logistical regression models were created. RESULTS: In 11 centers, 727 bailout procedures were conducted: 317 laparoscopic subtotal cholecystectomies, 172 open subtotal cholecystectomies, and 238 open cholecystectomies. Baseline characteristics were similar among subgroups. Bile leak was common in laparoscopic and open fenestrating subtotal cholecystectomies, with increased intraoperative drain placements and postoperative endoscopic retrograde cholangiopancreatography(P < .05). In contrast, intraoperative bleeding (odds ratio = 3.71 [1.9, 7.22]), surgical site infection (odds ratio = 2.41 [1.09, 5.3]), intensive care unit admission (odds ratio = 2.65 [1.51, 4.63]), and length of stay (Δ = 2 days, P < .001) were higher in open procedures. Reoperation rates were higher for open reconstituting subtotal cholecystectomies (odds ratio = 3.43 [1.03, 11.44]) than other subtypes. The overall rate of bile duct injury was 1.1% and was not statistically different between groups. Laparoscopic subtotal cholecystectomy had a bile duct injury rate of 0.63%. CONCLUSION: Laparoscopic subtotal cholecystectomy is a feasible surgical bailout procedure in cases of severe cholecystitis where standard laparoscopic cholecystectomy may carry undue risk of bile duct injury. Open cholecystectomy remains a reasonable option.

The impact of post-operative enteral nutrition on duodenal injury outcomes: A post hoc analysis of an EAST multicenter trial.

BACKGROUND: Leak following surgical repair of traumatic duodenal injuries results in prolonged hospitalization and oftentimes nil per os(NPO) treatment. Parenteral nutrition(PN) has known morbidity; however, duodenal leak(DL) patients often have complex injuries and hospital courses resulting in barriers to enteral nutrition(EN). We hypothesized EN alone would be associated with 1)shorter duration until leak closure and 2)less infectious complications and shorter hospital length of stay(HLOS) compared to PN. METHODS: This was a post-hoc analysis of a retrospective, multicenter study from 35 Level-1 trauma centers, including patients >14 years-old who underwent surgery for duodenal injuries(1/2010-12/2020) and endured post-operative DL. The study compared nutrition strategies: EN vs PN vs EN + PN using Chi-Square and Kruskal-Wallis tests; if significance was found pairwise comparison or Dunn's test were performed. RESULTS: There were 113 patients with DL: 43 EN, 22 PN, and 48 EN + PN. Patients were young(median age 28 years-old) males(83.2%) with penetrating injuries(81.4%). There was no difference in injury severity or critical illness among the groups, however there were more pancreatic injuries among PN groups. EN patients had less days NPO compared to both PN groups(12 days[IQR23] vs 40[54] vs 33[32],p = <0.001). Time until leak closure was less in EN patients when comparing the three groups(7 days[IQR14.5] vs 15[20.5] vs 25.5[55.8],p = 0.008). EN patients had less intra-abdominal abscesses, bacteremia, and days with drains than the PN groups(all p < 0.05). HLOS was shorter among EN patients vs both PN groups(27 days[24] vs 44[62] vs 45[31],p = 0.001). When controlling for predictors of leak, regression analysis demonstrated EN was associated with shorter HLOS(ß -24.9, 95%CI -39.0 to -10.7,p < 0.001). CONCLUSION: EN was associated with a shorter duration until leak closure, less infectious complications, and shorter length of stay. Contrary to some conventional thought, PN was not associated with decreased time until leak closure. We therefore suggest EN should be the preferred choice of nutrition in patients with duodenal leaks whenever feasible. LEVEL OF EVIDENCE: IV.

Predicting the time of mortality among older adult trauma patients: Is frailty the answer?

INTRODUCTION: This study aims to evaluate the temporal trends of mortality among frail versus non-frail older adult trauma patients during index hospitalization. METHODS: We performed a 3-year (2017-2019) analysis of ACS-TQIP. We included all older adult (age ≥65 years) trauma patients. Patients were stratified into two groups (Frail vs. Non-Frail). Outcomes were acute (<24 â€‹h), early (24-72 â€‹h), intermediate (72 hours-1 week), and late (>1 week) mortality. RESULTS: A total of 1,022,925 older adult trauma patients were identified, of which 19.7 â€‹% were frail. The mean(SD) age was 77(8) years and 57.4 â€‹% were female. Median[IQR] ISS was 9[4-10] and both groups had comparable injury severity (p â€‹= â€‹0.362). On multivariable analysis, frailty was not associated with acute (aOR 1.034; p â€‹= â€‹0.518) and early (aOR 1.190; p â€‹= â€‹0.392) mortality, while frail patients had independently higher odds of intermediate (aOR 1.269; p â€‹= â€‹0.042) and late (aOR 1.835; p â€‹< â€‹0.001) mortality. On sub-analysis, our results remained consistent in mild, moderate, and severely injured patients. CONCLUSION: Frailty is an independent predictor of mortality in older adult trauma patients who survive the initial 3 days of admission, regardless of injury severity.

The Role of Whole Blood Hemostatic Resuscitation in Bleeding Geriatric Trauma Patients.

INTRODUCTION: Whole blood (WB) has recently gained increased popularity as an adjunct to the resuscitation of hemorrhaging civilian trauma patients. We aimed to assess the nationwide outcomes of using WB as an adjunct to component therapy (CT) versus CT alone in resuscitating geriatric trauma patients. METHODS: We performed a 5-y (2017-2021) retrospective analysis of the Trauma Quality Improvement Program. We included geriatric (age, ≥65 y) trauma patients presenting with hemorrhagic shock (shock index >1) and requiring at least 4 units of packed red blood cells in 4 h. Patients with severe head injuries (head Abbreviated Injury Scale ≥3) and transferred patients were excluded. Patients were stratified into WB-CT versus CT only. Primary outcomes were 6-h, 24-h, and in-hospital mortality. Secondary outcomes were major complications. Multivariable regression analysis was performed, adjusting for potential confounding factors. RESULTS: A total of 1194 patients were identified, of which 141 (12%) received WB. The mean ± standard deviation age was 74 ± 7 y, 67.5% were male, and 83.4% had penetrating injuries. The median [interquartile range] Injury Severity Score was 19 [13-29], with no difference among study groups (P = 0.059). Overall, 6-h, 24-h, and in-hospital mortality were 16%, 23.1%, and 43.6%, respectively. On multivariable regression analysis, WB was independently associated with reduced 24-h (odds ratio, 0.62 [0.41-0.94]; P = 0.024), and in-hospital mortality (odds ratio, 0.60 [0.40-0.90]; P = 0.013), but not with major complications (odds ratio, 0.78 [0.53-1.15]; P = 0.207). CONCLUSIONS: Transfusion of WB as an adjunct to CT is associated with improved early and overall mortality in geriatric trauma patients presenting with severe hemorrhage. The findings from this study are clinically important, as this is an essential first step in prioritizing the selection of WB resuscitation for geriatric trauma patients presenting with hemorrhagic shock.

Initial Hemorrhage Control Procedure for Splenic Injuries May Affect Risk of Venous Thromboembolism.

INTRODUCTION: Venous thromboembolism (VTE) continues to be a major cause of morbidity in trauma. It is unclear whether the type of hemorrhage control procedure (i.e., splenectomy versus angioembolization) is associated with an increased risk of VTE. We hypothesize that hemodynamically stable patients undergoing angioembolization for blunt high-grade splenic injuries have lower rates of VTE compared to those undergoing splenectomy. METHODS: The American College of Surgeons Trauma Quality Program dataset from 2017 to 2019 was queried to identify all patients with American Association for the Surgery of Trauma grade 3-5 blunt splenic injuries. Outcomes including VTE rates were compared between those who were managed with splenectomy versus angioembolization. Propensity score matching (1:1) was performed adjusting for age, sex, initial vital signs, Injury Severity Score, and splenic injury grade. RESULTS: The analysis included 4698 matched patients (splenectomy [n = 2349] and angioembolization [n = 2349]). The median (interquartile range) age was 41 (27-58) years and 69% were male. Patients were well matched between groups. Angioembolization was associated with significantly lower VTE than splenectomy (2.2% versus 3.4%, P = 0.010) despite less use of VTE chemoprophylaxis (70% versus 80%, P < 0.001), as well as a relative delay in initiation of chemoprophylaxis (44 h versus 33 h, P < 0.001). Hospital and intensive care unit length of stay and mortality were also significantly lower in the angioembolization group. CONCLUSIONS: Angioembolization is associated with a significantly lower incidence of VTE than splenectomy. Thus, angioembolization should be considered for initial management of hemodynamically stable patients with high-grade blunt splenic injuries in whom laparotomy is not otherwise indicated.

Should We Keep or Transfer Our Severely Injured Geriatric Patients to Higher Levels of Care?

INTRODUCTION: Interfacility transfer to higher levels of care is becoming increasingly common. This study aims to evaluate the association between transfer to higher levels of care and prolonged transfer times with outcomes of severely injured geriatric trauma patients compared to those who are managed definitively at lower-level trauma centers. METHODS: Severely injured (Injury Severity Score >15) geriatric (≥60 y) trauma patients in the 2017-2018 American College of Surgeons Trauma Quality Improvement Program database managing at an American College of Surgeons/State Level III trauma center or transferring to a level I or II trauma center were included. Outcome measures were 24-h and in-hospital mortality and major complications. RESULTS: Forty thousand seven hundred nineteen patients were identified. Mean age was 75 ± 8 y, 54% were male, 98% had a blunt mechanism of injury, and the median Injury Severity Score was 17 [16-21]. Median transfer time was 112 [79-154] min, and the most common transport mode was ground ambulance (82.3%). Transfer to higher levels of care within 90 min was associated with lower 24-h mortality (adjusted odds ratio [aOR]: 0.493, P < 0.001) and similar odds of in-hospital mortality as those managed at level III centers. However, every 30-min delay in transfer time beyond 90 min was progressively associated with increased odds of 24-h (aOR: 1.058, P < 0.001) and in-hospital (aOR: 1.114, P < 0.001) mortality and major complications (aOR: 1.127, P < 0.001). CONCLUSIONS: Every 30-min delay in interfacility transfer time beyond 90 min is associated with 6% and 11% higher risk-adjusted odds of 24-h and in-hospital mortality, respectively. Estimated interfacility transfer time should be considered while deciding about transferring severely injured geriatric trauma patients to a higher level of care.

Intraosseous access in the resuscitation of patients with trauma: the good, the bad, the future.

The timely restoration of lost blood in hemorrhaging patients with trauma, especially those who are hemodynamically unstable, is of utmost importance. While intravenous access has traditionally been considered the primary method for vascular access, intraosseous (IO) access is gaining popularity as an alternative for patients with unsuccessful attempts. Previous studies have highlighted the higher success rate and easier training process associated with IO access compared with peripheral intravenous (PIV) and central intravenous access. However, the effectiveness of IO access in the early aggressive resuscitation of patients remains unclear. This review article aims to comprehensively discuss various aspects of IO access, including its advantages and disadvantages, and explore the existing literature on the clinical outcomes of patients with trauma undergoing resuscitation with IO versus intravenous access.

Pediatric Acute Compartment Syndrome in Long Bone Fractures: Who is at Risk?

INTRODUCTION: There is a paucity of large-scale data on the factors that suggest an impending or underlying extremity pediatric acute compartment syndrome (ACS). In addition, literature regarding the timing of operative fixation and the risk of ACS is mixed. We aimed to describe the factors associated with pediatric ACS. METHODS: Analysis of 2017-2019 Trauma Quality Improvement Program. We included patients aged <18 y diagnosed with upper extremity (UE) and lower extremity (LE) fractures. Burns and insect bites/stings were excluded. Multivariable regression analyses were performed to identify the predictors of ACS. RESULTS: 61,537 had LE fractures, of which 0.5% developed ACS. 76,216 had UE fractures, of which 0.16% developed ACS. Multivariable regression analyses identified increasing age, male gender, motorcycle collision, and pedestrian struck mechanisms of injury, comminuted and open fractures, tibial and concurrent tibial and fibular fractures, forearm fractures, and operative fixation as predictors of ACS (P value <0.05). Among LE fractures, 34% underwent open reduction internal fixation (time to operation = 14 [8-20] hours), and 2.1% underwent ExFix (time to operation = 9 [4-17] hours). Among UE fractures, 54% underwent open reduction internal fixation (time to operation = 11 [6-16] hours), and 1.9% underwent ExFix (time to operation = 9 [4-14] hours). Every hour delay in operative fixation of UE and LE fractures was associated with a 0.4% increase in the adjusted odds of ACS (P value <0.05). CONCLUSIONS: Our results may aid clinicians in recognizing children who are "at risk" for ACS. Future studies are warranted to explore the optimal timing for the operative fixation of long bone fractures to minimize the risk of pediatric ACS.

The Importance of Circulation in Airway Management: Preventing Post-Intubation Hypotension in The Trauma Bay.

OBJECTIVE: To identify the modifiable and non-modifiable risk factors associated with post-intubation hypotension (PIH) among trauma patients who required endotracheal intubation (ETI) in the trauma bay. SUMMARY BACKGROUND DATA: ETI has been associated with hemodynamic instability, termed PIH, yet its risk factors in trauma patients remain under-investigated. METHODS: This is a prospective observational study at a level I trauma center over 4 years (2019-2022). All adult (≥18) trauma patients requiring ETI in the trauma bay were included. Blood pressure was monitored both pre- and post-intubation. Multivariable logistic regression analysis was performed to identify the modifiable and non-modifiable factors associated with PIH. RESULTS: 708 patients required ETI in the trauma bay, of which, 435 (61.4%) developed PIH. The mean (SD) age was 43 (21) and 71% were male. Median [IQR] arrival GCS was 7 [3-13]. Patients who developed PIH had a lower mean (SD) pre-intubation SBP (118 (46) vs. 138 (28), P<0.001) and higher median [IQR] ISS (27 [21-38] vs. 21 [9-26], P<0.001). Multivariable regression analysis identified BMI>25, increasing ISS, penetrating injury, spinal cord injury, Pre-intubation PRBC requirements, and diabetes mellitus as non-modifiable risk factors associated with increased odds of PIH. In contrast, pre-intubation administration of 3% hypertonic saline and vasopressors were identified as the modifiable factors significantly associated with reduced PIH. CONCLUSION: More than half of the patients requiring ETI in the trauma bay developed PIH. This study identified modifiable and non-modifiable risk factors that influence the development of PIH, which will help physicians when considering ETI upon patient arrival. LEVEL OF EVIDENCE: Level III, Prognostic Study.

The role of number of affected vessels on radiologic and clinical outcomes of patients with blunt cerebrovascular injury.

OBJECTIVE: There is a lack of data on the role of characteristics of injured vessels on the outcomes of patients with blunt cerebrovascular injuries (BCVIs). The aim of this study was to assess the effect of the number (single vs multiple) of injured vessels on outcomes. METHODS: This is a retrospective study at two American College of Surgeons Level I trauma centers (2017-2021). Adult (>16 years) trauma patients with BCVIs are included. Injuries were graded by the Denver Scale based on the initial computed tomography angiography (CTA). Early repeat CTA was performed 7 to 10 days after diagnosis. Patients were stratified by the number (single vs multiple) of the involved vessels. Outcomes included progression of BCVIs on repeat CTA, stroke, and in-hospital mortality attributable to BCVIs. Multivariable regression analyses were performed to identify the association between the number of injured vessels and outcomes. RESULTS: A total of 491 patients with 591 injured vessels (285 carotid and 306 vertebral arteries) were identified. Sixty percent were male, the mean age was 44 years, and the median Injury Severity Score was 18 (interquartile range, 11-25). Overall, 18% had multiple-vessel injuries, 16% had bilateral vessel injuries, and 3% had multiple injuries on the same side. The overall rates of progression to higher-grade injuries, stroke, and mortality were 23%, 7.7%, and 8.8%, respectively. On uni- and multivariable analyses, multiple BCVIs were associated with progression to higher-grade injuries on repeat imaging, stroke, and mortality compared with single-vessel injuries. CONCLUSIONS: BCVIs with multiple injured vessels are more likely to progress to higher grades on repeat CTA, with multiple injuries independently associated with worse clinical outcomes, compared with those with single injuries. These findings highlight the importance of incorporating the number of injured vessels in clinical decision-making and in defining protocols for repeat imaging.

An executive summary of the National Trauma Research Action Plan.

ABSTRACT: The National Trauma Research Action Plan project successfully engaged multidisciplinary experts to define opportunities to advance trauma research and has fulfilled the recommendations related to trauma research from the National Academies of Sciences, Engineering and Medicine report. These panels identified more than 4,800 gaps in our knowledge regarding injury prevention and the optimal care of injured patients and laid out a priority framework and tools to support researchers to advance this field. Trauma research funding agencies and researchers can use this executive summary and supporting manuscripts to strategically address and close the highest priority research gaps. Given that this is the most significant public health threat facing our children, young adults, and military service personnel, we must do better in prioritizing these research projects for funding and providing grant support to advance this work. Through the Coalition for National Trauma Research, the trauma community is committed to a coordinated, collaborative approach to address these critical knowledge gaps and ultimately reduce the burden of morbidity and mortality faced by our patients.
