Unhoused and Injured: Injury Characteristics and Outcomes in Unhoused Trauma Patients.

INTRODUCTION: The unhoused population is known to be at high risk for traumatic injury. However, there are scarce data regarding injury patterns and outcomes for this patient group. This study aims to investigate any differences in injury characteristics and hospital outcomes between unhoused and housed patients presenting with traumatic injuries. METHODS: We conducted a 3-y retrospective cohort study at a level 1 trauma center in a metropolitan area with a large unhoused population. All adult trauma patients who were identified as unhoused or housed underinsured (HUI) were included in the study. Injury characteristics, comorbidities, and hospital outcomes were compared between the two groups. RESULTS: A total of 8450 patients were identified, of which 7.5% were unhoused. Compared to HUI patients, unhoused patients were more likely to sustain minor injuries (65.2% versus 59.1%, P = 0.003) and more likely to be injured by assault (17.9% versus 12.4%, P < 0.001), stab wound (17.7% versus 10.8%, P < 0.001), and automobile versus pedestrian or bike (21.0% versus 15.8% P < 0.001). We found that unhoused patients had higher odds of mortality (adjusted odds ratio [AOR]: 1.93, 95% confidence interval [CI]: 1.10-3.36, P = 0.021), brain death (AOR: 5.40, 95% CI: 2.11-13.83, P < 0.001), bacteremia/sepsis (AOR: 4.36, 95% CI: 1.20-15.81, P = 0.025), and increased hospital length of stay (regression coefficient: 0.08, 95% CI: 0.03-0.12, P = 0.003). CONCLUSIONS: This study observed significant disparities in injury characteristics and hospital outcomes between the unhoused and HUI groups. Our results suggest that these disparities are impacted by social determinants of health unique to the unhoused population.

Risk factors for stroke in penetrating cerebrovascular injuries.

OBJECTIVE: Penetrating cerebrovascular injuries (PCVI) are associated with a high incidence of mortality and neurological events. The optimal treatment strategy of PCVI, especially when damage control measures are required, remains controversial. The aim of this study was to describe the management of PCVI and patient outcomes at a level 1 trauma center where vascular injuries are managed predominantly by trauma surgeons. METHODS: An institutional trauma registry was queried for patients with PCVI from 2011 to 2021. Patients with common carotid artery (CCA), internal carotid artery (ICA), or vertebral artery injuries were included for analysis. The primary outcome was in-hospital stroke. The secondary outcomes were in-hospital mortality and in-hospital stroke or death. A subgroup analysis was completed of arterial repair (primary repair or interposition graft) vs ligation or embolization vs temporary intravascular shunting at the index procedure. RESULTS: We analyzed 54 patients with PCVI. Overall, the in-hospital stroke rate was 17% and in-hospital mortality was 26%. Twenty-one patients (39%) underwent arterial interventions for PCVI. Ten patients underwent arterial repair, six patients underwent ligation or embolization, and five patients underwent intravascular shunting as a damage control strategy with a plan for delayed repair. The rate of in-hospital stroke was 30% after arterial repair, 0% after arterial ligation or embolization, and 80% after temporary intravascular shunting. There was a significant difference in the stroke rate between the three subgroups (P = .015). Of the 32 patients who did not have an intervention to the CCA, ICA, or vertebral artery, 1 patient with ICA occlusion and 1 patient with CCA intimal injury developed in-hospital stroke. The mortality rate was 0% after arterial repair, 50% after ligation or embolization, and 60% after intravascular shunting. The rate of stroke or death was 30% in the arterial repair group, 50% in the ligation or embolization group, and 100% in the temporary intravascular shunting group. CONCLUSIONS: High rates of stroke and mortality were seen in patients requiring damage control after PCVI. In particular, temporary intravascular shunting was associated with a high incidence of in-hospital stroke and a 100% rate of stroke or death. Further investigation is needed into the factors related to these finding and whether the use of temporary intravascular shunting in PCVI is an advisable strategy.

Mechanism Matters: Differential benefits of cold-stored whole blood for trauma resuscitation from a prospective multicenter study.

BACKGROUND: Resuscitation with cold-stored low-titre whole blood (LTOWB) has increased despite the paucity of robust civilian data. Most studies are in predominately blunt trauma and lack analysis of specific subgroups or mechanism of injury. We sought to compare outcomes between patients receiving LTOWB vs. balanced component therapy (BCT) after blunt (BL) and penetrating (PN) trauma. METHODS: Secondary analysis of a prospective multicenter study of patients receiving either LTWOB-containing or BCT resuscitation was performed. Patients were grouped by mechanism of injury (BL vs PN). A generalized estimated equations model using inverse probability of treatment weighting was employed. Primary outcome was mortality and secondary outcomes were acute kidney injury, venous thromboembolism, pulmonary complications, and bleeding complications. Additional analyses were performed on non-traumatic brain injury (TBI), severe torso injury, and LTOWB-only resuscitation patients. RESULTS: 1617 patients (BL 47% vs PN 54%) were identified; 1175 (73%) of which received LTOWB. PN trauma patients receiving LTOWB demonstrated improved survival compared to BCT (77% vs. 56%; p<0.01). Interval survival was higher at 6 hrs (95% vs. 88%), 12 hrs (93% vs. 80%) and 24 hrs (88% vs. 57%) (all p<0.05). The survival benefit following LTOWB was also seen across PN non-TBI (83% vs. 52%), and severe torso injuries (75% vs. 43%) (all p <0.05). After controlling for age, sex, injury severity, and trauma center, LTWOB was associated with decreased odds of death (OR .31, p<.05) in PN trauma. However, no difference in overall mortality was seen across the BL groups. Both PN and BL patients receiving LTOWB had more frequent AKI compared to BCT (19% vs. 7% and 12% vs 6%, respectively; p<0.05). CONCLUSIONS: LTOWB resuscitation was independently associated with decreased mortality following PN trauma, but not BL trauma. Further analysis in BL trauma is required to identify subgroups that may demonstrate survival benefit. LEVEL OF EVIDENCE: Therapeutic/Care Management, III.

Building Geriatric Trauma Programs in Resource-Constrained Environments: Trauma Quality Improvement Program Guideline Implementation at Two Safety Net Hospitals in Southern California.

Background: To improve care of geriatric trauma patients, the American College of Surgeons (ACS) Trauma Quality Improvement Program (TQIP) updated guidelines in 2021. Amid geriatrician shortages in Southern California, 2 Los Angeles County safety net hospitals were tasked with creating a strategy to meet geriatric trauma guidelines despite constrained resources. Methods: All trauma patients ≥ 60 years admitted to a safety net hospital in Southern California were enrolled without exclusions (August 2022-April 2023). Primary outcome was frailty screening with documentation to identify older trauma patients at a high risk for adverse outcomes. Results: Needs assessment discovered no standardized process to identify high-risk geriatric patients, no geriatric care guidelines, and no inpatient geriatric consultation service. An action plan composed of a resident-led frailty screen resulted in identification of high-risk patients. Overall, 217 patients met criteria. Ninety-six patients (44%) successfully underwent frailty screening. Frailty screening compliance increased over the study, beginning at 37% capture in the first month and increasing to 81% in the final study month. After achieving nearly uniform frailty screening, a form was developed for the EMR for ease of documentation, data capture/tracking, and compliance monitoring. Discussion: In this study, creativity, collaboration, and resourcefulness allowed TQIP guideline implementation at 2 county hospitals. A systematic process is now in place to identify and triage high-risk geriatric trauma patients based on frailty screen to receive inpatient medicine consultation for medical comorbidity optimization. Continued interdisciplinary and interfacility collaboration will be crucial for continued delivery of the optimal care to older injured patients.

An Abdominal Seat Belt Sign is Associated With Similar Incidence of Hollow Viscus Injury but Increased In-Hospital Mortality in Older Adult Trauma Patients: A PCSA Multicenter Study.

BACKGROUND: The abdominal seat belt sign (SBS) is associated with an increased risk of hollow viscus injury (HVI). Older age is associated with worse outcomes in trauma patients. Thus, older trauma patients ≥65 years of age (OTPs) may be at an increased risk of HVI with abdominal SBS. Therefore, we hypothesized an increased incidence of HVI and mortality for OTPs vs younger trauma patients (YTPs) with abdominal SBS. STUDY DESIGN: This post hoc analysis of a multi-institutional, prospective, observational study (8/2020-10/2021) included patients >18 years old with an abdominal SBS who underwent abdominal computed tomography (CT) imaging. Older trauma patients were compared to YTPs (18-64 years old) with bivariate analyses. RESULTS: Of the 754 patients included in this study from nine level-1 trauma centers, there were 110 (14.6%) OTPs and 644 (85.4%) YTPs. Older trauma patients were older (mean 75.3 vs 35.8 years old, P < .01) and had a higher mean Injury Severity Score (10.8 vs 9.0, P = .02). However, YTPs had an increased abdominal abbreviated-injury scale score (2.01 vs 1.63, P = .02). On CT imaging, OTPs less commonly had intraabdominal free fluid (21.7% vs 11.9%, P = .02) despite a similar rate of abdominal soft tissue contusion (P > .05). Older trauma patients also had a statistically similar rate of HVI vs YTPs (5.5% vs 9.8%, P = .15). Despite this, OTPs had increased mortality (5.5% vs 1.1%, P < .01) and length of stay (LOS) (5.9 vs 4.9 days P < .01). CONCLUSION: Despite a similar rate of HVI, OTPs with an abdominal SBS had an increased rate of mortality and LOS. This suggests the need for heightened vigilance when caring for OTPs with abdominal SBS.

Is barbed better? Evaluation of triclosan-coated barbed suture on wound complications following emergency laparotomy.

INTRODUCTION: Emergent laparotomy is associated with significant wound complications including surgical site infections (SSIs) and fascial dehiscence. Triclosan-coated barbed (TCB) suture for fascial closure has been shown to reduce local complications but primarily in elective settings. We sought to evaluate the effect of TCB emergency laparotomy fascial closure on major wound complications. METHODS: Adult patients undergoing emergency laparotomy were prospectively evaluated over 1 year. Patients were grouped into TCB versus polydioxanone (PDS) for fascial closure. Subanalysis was performed on patients undergoing single-stage laparotomy. Primary outcomes were SSI and fascial dehiscence. Multivariate analysis identified independent factors associated with SSI and fascial dehiscence. RESULTS: Of the 206 laparotomies, 73 (35%) were closed with TCB, and 133 (65%) were closed with PDS. Trauma was the reason for laparotomy in 73% of cases; damage-control laparotomy was performed in 27% of cases. The overall rate of SSI and fascial dehiscence was 18% and 10%, respectively. Operative strategy was similar between groups, including damage-control laparotomy, wound vac use, skin closure, and blood products. Surgical site infection events trended lower with TCB versus PDS closure (11% vs. 21%, p = 0.07), and fascial dehiscence was significantly lower with TCB versus PDS (4% vs. 14%, p < 0.05). Subanalysis of trauma and nontrauma cases showed no difference in SSI or fascial dehiscence. Multivariable analysis found that TCB decreased the likelihood of fascial dehiscence (odds ratio, 0.07; p < 0.05) following emergency laparotomy. Increased odds of fascial dehiscence were seen in damage-control laparotomy (odds ratio, 3.1; p < 0.05). CONCLUSION: Emergency laparotomy fascial closure with TCB showed significantly decreased rates of fascial dehiscence compared with closure with PDS and a strong trend toward lower SSI events. Triclosan-coated barbed suture was independently associated with decreased fascial dehiscence rates after emergency laparotomy. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

Identifying Pregnant Patients With Suspected Intimate Partner Violence.

INTRODUCTION: Intimate partner violence (IPV) is the leading cause of death in pregnant women. Although it can be difficult to identify patients experiencing IPV, injuries to the head, neck, or face due to an assault are known to correlate with intentional injury. The objective of this study is to assess the contemporary burden of IPV in pregnancy and describe the patient characteristics. METHODS: The National Inpatient Sample was queried for all pregnant women between January 2016 and December 2019. Patients were divided into two groups: suspected IPV (SIPV) and no-SIPV groups. We defined SIPV as any pregnant patient with an identified head, neck, or face injuries categorized as intentional assault. Multivariable logistic regression analysis was performed to assess the association between SIPV and variables of interest. RESULTS: A total of 28,540 pregnant patients presented with traumatic injuries with 530 (.02%) identified as SIPV. Suspected IPV patients were younger (25 vs 27 years, P = .012), more likely to be of Black race (46% vs 28%, P = .002), more likely to be in the lowest income quartile (51% vs 38%, P = .031), less likely to have private insurance (12% vs 34%, P < .001), and have higher rates of substance use disorder (35% vs 18%, P < .001). Black race and history of substance use disorder were associated with increased odds of SIPV-related injuries (odds ratio [OR]: 2.01, interquartile range [IQR]: 1.27-3.16, P = .003 and OR: 2.30, IQR 1.54-3.43, P < .001, respectively). CONCLUSIONS: Our results suggest that there are significant racial and socioeconomic disparities in potential risk for IPV during pregnancy.

Bile Duct Injuries During Urgent Cholecystectomy at a Safety Net Teaching Hospital: Attending Experience and Time of Day May Matter.

Background: Bile duct injury (BDI) is one of the most severe complications during cholecystectomy. Early identification of risk factors for BDI may permit risk reduction strategies and inform patient consent.Objective: This study aimed to define patient, provider, and systemic factors associated with BDI; BDI incidence; and short-term outcomes of BDI after urgent cholecystectomy.Methods: Patients who underwent urgent cholecystectomy for acute cholecystitis were retrospectively screened (2020-2022). All patients who sustained BDI were included without exclusions. Demographics, clinical data, and outcomes were collected and compared with descriptive statistics.Results: During the study period, BDI occurred in 4 (0.5%) of 728 patients who underwent urgent cholecystectomy for acute cholecystitis. Most BDI cases (75%) took place overnight or during the weekend. The attending surgeon was almost exclusively (75%) in their first year of practice. BDI was recognized during index operation in 2 cases (50%). Hepatobiliary surgery performed the bile duct repair in all 4 cases. Two complications occurred (50%). All patients were followed by hepatobiliary surgery in the outpatient setting and returned to their baseline level of function within 2 months of hospital discharge.Conclusion: Most BDI occurred in procedures attended by first-year faculty during after hours cholecystectomies, suggesting a role for increased proctorship in early career attendings in addition to in-hours cholecystectomy for acute cholecystitis. The timely return to baseline function experienced by these patients emphasizes the favorable outcomes associated with early recognition of BDI and involvement of hepatobiliary surgery. Further examination with multicenter evaluation would be beneficial to validate these study findings.

Non-Binary Trauma Patients: Delineating a Vulnerable, At-Risk Population.

INTRODUCTION: An increasing proportion of the population identifies as non-binary. This marginalized group may be at differential risk for trauma compared to those who identify as male or female, but physical trauma among non-binary patients has not yet been examined at a national level. METHODS: All patients aged ≥ 16 years in the National Trauma Data Bank were included (2021-2022). Demographics, injury characteristics, and outcomes after trauma among non-binary patients were compared to males and females. The goal was to delineate differences between groups to inform the care and future study of non-binary trauma patients. RESULTS: In total, 1,012,348 patients were included: 283 (<1%) non-binary, 610,904 (60%) male, and 403,161 (40%) female patients. Non-binary patients were younger than males or females (median age 44 vs 49 vs 67 years, P < .001) and less likely to be White race/ethnicity (58% vs 60% vs 74%, P < .001). Despite non-binary patients having a lower median Injury Severity Score (5 vs 9 vs 9, P < .001), mortality was highest among non-binary and male patients than females (5% vs 5% vs 3%, P < .001). DISCUSSION: In this study, non-binary trauma patients were younger and more likely minority races/ethnicities than males or females. Despite having a lower injury severity, non-binary patient mortality rates were comparable to those of males and greater than for females. These disparities identify non-binary trauma patients as doubly marginalized, by gender and race/ethnicity, who experience worse outcomes after trauma than expected based on injury severity. This vulnerable patient population deserves further study to identify areas for improved trauma delivery care.

Back on the Streets: Examining Emergency Department Return Rates for Unhoused Patients Discharged After Trauma.

BACKGROUND: The unhoused population is at high risk for traumatic injuries and faces unique challenges in accessing follow-up care. However, there is scarce data regarding differences in Emergency Department (ED) return rates and reasons for return between unhoused and housed patients. METHODS: We conducted a 3-year retrospective cohort study at a level-1 trauma center in a large metropolitan area. All patients who presented to the ED with traumatic injuries and were discharged without hospital admission were included in the study. The primary outcome was ED returns for trauma-related complications or new traumatic events <6 months after discharge. Patient characteristics and study outcomes were compared between housed and unhoused groups. RESULTS: A total of 4184 patients were identified, of which 20.3% were unhoused. Compared to housed, unhoused patients were more likely to return to the ED (18.8% vs 13.9%, P < .001), more likely to return for trauma-related complications (4.6% vs 3.1%, P = .045), more likely to return with new trauma (7.1% vs 2.8%, P < .001), and less likely to return for scheduled wound checks (2.5% vs 4.3%, P = .012). Of the patients who returned with trauma-related complications, unhoused patients had a higher proportion of wound infection (20.5% vs 5.7%, P = .008). In the regression analysis, unhoused status was associated with increased odds of ED return with new trauma and decreased odds of return for scheduled wound checks. CONCLUSIONS: This study observed significant disparities between unhoused and housed patients after trauma. Our results suggest that inadequate follow-up in unhoused patients may contribute to further ED return.

Immediate Operative Trauma Assessment Score: A Simple and Reliable Predictor of Mortality in Trauma Patients Undergoing Urgent/Emergent Surgery.

Objective: Many current trauma mortality prediction tools are either too intricate or rely on data not readily available during a trauma patient's initial evaluation. Moreover, none are tailored to those necessitating urgent or emergent surgery. Our objective was to design a practical, user-friendly scoring tool using immediately available variables, and then compare its efficacy to the widely-known Revised Trauma Score (RTS). Methods: The adult 2017-2021 Trauma Quality Improvement Program (TQIP) database was queried to identify patients ≥18 years old undergoing any urgent/emergent operation (direct from Emergency Department to operating room). Patients were divided into derivation and validation groups. A three-step methodology was used. First, multiple logistic regression models were created to determine risk of death using only variables available upon arrival. Second, the weighted average and relative impact of each independent predictor was used to derive an easily calculated Immediate Operative Trauma Assessment Score (IOTAS). We then validated IOTAS using AUROC and compared it to RTS. Results: From 249 208 patients in the derivation-set, 14 635 (5.9%) died. Age ≥65, Glasgow Coma Scale score <9, hypotension (SBP <90 mmHg), and tachycardia (>120/min) on arrival were identified as independent predictors for mortality. Using these, the IOTAS was structured, offering scores between 0-8. The AUROC for this was .88. A clear escalation in mortality was observed across scores: from 4.4% at score 1 to 60.5% at score 8. For the validation set (250 182 patients; mortality rate 5.8%), the AUROC remained consistent at .87, surpassing RTS's AUROC of .83. Conclusion: IOTAS is a novel, accurate, and now validated tool that is intuitive and efficient in predicting mortality for trauma patients requiring urgent or emergent surgeries. It outperforms RTS, and thereby may help guide clinicians when determining the best course of action in patient management as well as counseling patients and their families.

A collaborative multidisciplinary trauma program improvement team improves VTE chemoprophylaxis guideline compliance in non-operative stable TBI.

BACKGROUND: Delays in initiating venous thromboembolism (VTE) prophylaxis in patients suffering from traumatic brain injury (TBI) persist despite guidelines recommending early initiation. We hypothesized that the expansion of a Trauma Program Performance Improvement (PI) team will improve compliance of early (24-48 hours) initiation of VTE prophylaxis and will decrease VTE events in TBI patients. METHODS: We performed a single-center retrospective review of all TBI patients admitted to a Level I trauma center before (2015-2016,) and after (2019-2020,) the expansion of the Trauma Performance Improvement and Patient Safety (PIPS) team and the creation of trauma process and outcome dashboards. Exclusion criteria included discharge or death within 48 hours of admission, expanding intracranial hemorrhage on CT scan, and a neurosurgical intervention (craniotomy, pressure monitor, or drains) prior to chemoprophylaxis initiation. RESULTS: A total of 1,112 patients met the inclusion criteria, of which 54% (n = 604) were admitted after Trauma PIPS expansion. Following the addition of a dedicated PIPS nurse in the trauma program and creation of process dashboards, the time from stable CT to VTE prophylaxis initiation decreased (52 hours to 35 hours; p < 0.001) and more patients received chemoprophylaxis at 24 hours to 48 hours (59% from 36%, p < 0.001) after stable head CT. There was no significant difference in time from first head CT to stable CT (9 vs. 9 hours; p = 0.15). The Contemporary group had a lower rate of VTE events (1% vs. 4%; p < 0.001) with no increase in bleeding events (2% vs. 2%; p = 0.97). On multivariable analysis, being in the Early cohort was an independent predictor of VTE events (adjusted odds ratio, 3.74; 95% confidence interval, 1.45-6.16). CONCLUSION: A collaborative multidisciplinary Trauma PIPS team improves guideline compliance. Initiation of VTE chemoprophylaxis within 24 hours to 48 hours of stable head CT is safe and effective. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Clinical factors and outcomes of spleen-conserving surgery versus total splenectomy in splenic injuries: A nationwide database study.

BACKGROUND: The objective of this study was to identify factors associated with the use of spleen-conserving surgeries, as well as patient outcomes, on a national scale. METHODS: This retrospective cohort study (2010-2015) included patients (age≥16 years) with splenic injury in the National Trauma Data Bank. Patients who received a total splenectomy or a spleen-conserving surgery were compared for demographics and clinical outcomes. RESULTS: During the study period, 18,425 received a total splenectomy and 1,825 received a spleen-conserving surgery. Total splenectomy was more likely to be performed for patients with age>65 (odds ratio [OR]: 0.63, p â€‹< â€‹0.001), systolic blood pressure<90 (OR: 0.63, p â€‹< â€‹0.001), heart rate>120 (OR: 0.83, p â€‹= â€‹0.007), and high-grade injuries (OR: 0.18, p â€‹< â€‹0.001). Penetrating trauma patients were more likely to undergo a spleen-conserving surgery (OR: 3.31, p â€‹< â€‹0.001). The use of spleen-conserving surgery was associated with a lower risk of pneumonia (OR: 0.79, p â€‹= â€‹0.009) and venous thromboembolism (OR: 0.72, p â€‹= â€‹0.006). CONCLUSIONS: Spleen-conserving surgeries may be considered for patients with penetrating trauma, age<65, hemodynamic stability, and low-grade injuries. Spleen-conserving surgeries have decreased risk of pneumonia and venous thromboembolism.

Outcomes of severely injured pregnant trauma patients: a multicenter analysis.

Nearly 10% of pregnant women suffer traumatic injury. Clinical outcomes for pregnant trauma patients (PTPs) with severe injuries have not been well studied. We sought to describe outcomes for PTPs presenting with severe injuries, hypothesizing that PTPs with severe injuries will have higher rates of complications and mortality compared to less injured PTPs. A post-hoc analysis of a multi-institutional retrospective study at 12 Level-I/II trauma centers was performed. Patients were stratified into severely injured (injury severity score [ISS] > 15) and not severely injured (ISS < 15) and compared with bivariate analyses. From 950 patients, 32 (3.4%) had severe injuries. Compared to non-severely injured PTPs, severely injured PTPs were of similar maternal age but had younger gestational age (21 vs 26 weeks, p = 0.009). Penetrating trauma was more common in the severely injured cohort (15.6% vs 1.4%, p < 0.001). The severely injured cohort more often underwent an operation (68.8% vs 3.8%, p < 0.001), including a hysterectomy (6.3% vs 0.3%, p < 0.001). The severely injured group had higher rates of complications (34.4% vs 0.9%, p < 0.001), mortality (15.6% vs 0.1%, p < 0.001), a higher rate of fetal delivery (37.5% vs. 6.0%, p < 0.001) and resuscitative hysterotomy (9.4% vs. 0%, p < 0.001). Only approximately 3% of PTPs were severely injured. However, severely injured PTPs had a nearly 40% rate of fetal delivery as well as increased complications and mortality. This included a resuscitative hysterotomy rate of nearly 10%. Significant vigilance must remain when caring for this population.

Open versus endovascular repair of penetrating non-aortic arterial injuries: A systematic review and meta analysis.

BACKGROUND: Non-aortic arterial injuries are common and are associated with high morbidity and mortality. Historically, open surgical repair (OSR) was the conventional method of repair. With recent advancements in minimally invasive techniques, endovascular repair (ER) has gained popularity. We sought to compare outcomes in patients undergoing endovascular and open repairs of traumatic non-aortic penetrating arterial injuries. METHODS: A systematic review and meta-analysis was conducted using MEDLINE (OVID), Web of Science, Cochrane Library, and Scopus Database from January 1st, 1990, to March 20th, 2023. Titles and abstracts were screened, followed by full text review. Articles assessing clinically important outcomes between OSR and ER in penetrating arterial injuries were included. Exclusion criteria included blunt injuries, aortic injuries, pediatric populations, review articles, and non-English articles. Odds ratios (OR) and Cohen's d ratios were used to quantify differences in morbidity and mortality. RESULTS: A total of 3770 articles were identified, of which 8 met inclusion criteria and were included in the review. The articles comprised a total of 8369 patients of whom 90 % were male with a median age of 28 years. 85 % of patients were treated with OSR while 15 % underwent ER. With regards to injury characteristics, those who underwent ER were less likely to present with concurrent venous injuries (OR: 0.41; 95 %CI: 0.18, 0.94; p = 0.03). Regarding hospital outcomes, patients who underwent ER had a lower likelihood of in-hospital or 30-day mortality (OR: 0.72; 95 %CI: 0.55, 0.95; p = 0.02) and compartment syndrome (OR: 0.29, 95 %CI: 0.12, 0.71; p = 0.007). The overall risk of bias was moderate. CONCLUSION: Endovascular repair of non-aortic penetrating arterial injuries is increasingly common, however open repair remains the most common approach. Compared to ER, OSR was associated with higher odds of compartment syndrome and mortality. Further prospective research is warranted to determine the patient populations and injury patterns that most significantly benefit from an endovascular approach.

Early venous thromboembolism chemoprophylaxis in traumatic brain injury requiring neurosurgical intervention: Safe and effective.

BACKGROUND: Traumatic brain injury patients who require neurosurgical intervention are at the highest risk of worsening intracranial hemorrhage. This subgroup of patients has frequently been excluded from prior research regarding the timing of venous thromboembolism chemoprophylaxis. This study aims to assess the efficacy and safety of early venous thromboembolism chemoprophylaxis in patients with traumatic brain injuries requiring neurosurgical interventions. METHODS: This is a single-center retrospective review (2016-2020) of traumatic brain injury patients requiring neurosurgical intervention admitted to a level I trauma center. Interventions included intracranial pressure monitoring, subdural drain, external ventricular drain, craniotomy, and craniectomy. Exclusion criteria included neurosurgical intervention after chemoprophylaxis initiation, death within 5 days of admission, and absence of chemoprophylaxis. The total population was stratified into Early (≤72 hours of intervention) versus Late (>72 hours after intervention) chemoprophylaxis initiation. RESULTS: A total of 351 patients met the inclusion criteria, of whom 204 (58%) had early chemoprophylaxis initiation. Overall, there were no significant differences in baseline and admission characteristics between cohorts. The Early chemoprophylaxis cohort had a statistically significant lower venous thromboembolism rate (5% vs 13%, P < .001) with no increased risk of worsening intracranial hemorrhage (10% vs 13%, P = .44) or neurosurgical reintervention (8% vs 10%, P = .7). On subgroup analysis, a total of 169 patients required either a craniotomy or a craniectomy before chemoprophylaxis. The Early chemoprophylaxis cohort had statistically significant lower venous thromboembolism rates (2% vs 11%, P < .001) with no increase in intracranial hemorrhage (8% vs 11%, P = .6) or repeat neurosurgical intervention (8% vs 10%, P = .77). CONCLUSION: Venous thromboembolism prophylaxis initiation within 72 hours of neurosurgical intervention is safe and effective. Further prospective research is warranted to validate the results of this study.

Recent Changes in the Management of High-Grade Blunt Pancreatic Injury in Children: A Nationwide Trend Analysis.

BACKGROUND: The optimal management of pediatric patients with high-grade blunt pancreatic injury (BPI) involving the main pancreatic duct remains controversial. This study aimed to assess the nationwide trends in the management of pediatric high-grade BPI at pediatric (PTC), mixed (MTC), and adult trauma centers (ATC). STUDY DESIGN: This is a retrospective observational study of the National Trauma Data Bank. We included pediatric patients (age 16 years or less) sustaining high-grade BPI (Abbreviated Injury Scale 3 or more) from 2011 to 2021. Patients who did not undergo pancreatic operation were categorized into the nonoperative management (NOM) group. Trauma centers were defined as PTC (level I/II pediatric only), MTC (level I/II adult and pediatric), and ATC (level I/II adult only). Primary outcome was the proportion of patients undergoing NOM, and secondary outcomes included the use of ERCP and in-hospital mortality. A Cochran-Armitage test was used to analyze the trend. RESULTS: A total of 811 patients were analyzed. The median age was 9 years (interquartile range 6 to 13), 64% were male patients, and the median injury severity score was 17 (interquartile range 10 to 25). During the study period, there was a significant upward linear trend in the use of NOM and ERCP among the overall cohort (range 48% to 66%; p trend = 0.033, range 6.1% to 19%; p trend = 0.030, respectively). The significant upward trend for NOM was maintained in the subgroup of patients at PTC and MTC (p trend = 0.037), whereas no significant trend was observed at ATC (p trend = 0.61). There was no significant trend in in-hospital mortality (p trend = 0.38). CONCLUSIONS: For the management of pediatric patients with high-grade BPI, this study found a significant trend toward increasing use of NOM and ERCP without mortality deterioration, especially at PTC and MTC.

Disruption of trauma research: an analysis of the top cited versus disruptive trauma research publications.

Introduction: The analysis of surgical research using bibliometric measures has become increasingly prevalent. Absolute citation counts (CC) or indices are commonly used markers of research quality but may not adequately capture the most impactful research. A novel scoring system, the disruptive score (DS) has been found to identity academic work that either changes paradigms (disruptive (DIS) work) or entrenches ideas (developmental (DEV) work). We sought to analyze the most DIS and DEV versus most cited research in civilian trauma. Methods: The top papers by DS and by CC from trauma and surgery journals were identified via a professional literature search. The identified publications were then linked to the National Institutes of Health iCite tool to quantify total CC and related metrics. The top 100 DIS and DEV publications by DS were analyzed based on the area of focus, citation, and perceived clinical impact, and compared with the top 100 papers by CC. Results: 32 293 articles published between 1954 and 2014 were identified. The most common publication location of selected articles was published in Journal of Trauma (31%). Retrospective reviews (73%) were common in DIS (73%) and top CC (67%) papers, while DEV papers were frequently case reports (49%). Only 1 publication was identified in the top 100 DIS and top 100 CC lists. There was no significant correlation between CC and DS among the top 100 DIS papers (r=0.02; p=0.85), and only a weak correlation between CC and DS score (r=0.21; p<0.05) among the top 100 DEV papers. Conclusion: The disruption score identifies a unique subset of trauma academia. The most DIS trauma literature is highly distinct and has little overlap with top trauma publications identified by standard CC metrics, with no significant correlation between the CC and DS. Level of evidence: Level IV.
