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.

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.

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 (SSI) and fascial dehiscence (FD). Triclosan-coated barbed suture (TCB) 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 vs polydioxanone (PDS) for fascial closure. Subanalysis was performed on patients undergoing single-stage laparotomy. Primary outcomes were SSI and FD. Multivariate analysis identified independent factors associated with SSI and FD. 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 (DCL) was performed in 27% of cases. The overall rate of SSI and FD was 18% and 10%, respectively. Operative strategy was similar between groups, including DCL, wound vac use, skin closure, and blood products. SSI events trended lower with TCB vs PDS closure (11% vs. 21%; p = .07), and FD was significantly lower with TCB versus PDS (4% vs. 14%; p < .05, Fig 1). Subanalysis of trauma and non-trauma cases showed no difference in SSI or FD. Multivariable analysis found that TCB decreased the likelihood of FD (OR .07; p < .05, Fig 2) following emergency laparotomy. Increased odds of FD were seen in DCL (OR 3.1; p < 0.05). CONCLUSIONS: Emergency laparotomy fascial closure with TCB showed significantly decreased rates of FD compared to closure with PDS, and a strong trend toward lower SSI events. TCB was independently associated with decreased FD rates after emergency laparotomy.

Persistent disparities between trauma center types in the management of children with high-grade blunt splenic injuries.

BACKGROUND: In the early 2000s, substantial variations were reported in the management of pediatric patients with blunt splenic injury (BSI). The purpose of this study was to assess the recent trends and disparities between different types of trauma centers. We hypothesized that there would be persistent disparities despite decreased trends in the rate of splenectomy. METHODS: This is a retrospective cohort study using the American College of Surgeons Trauma Quality Improvement Program database. We included patients (age ≤18 years) with high-grade BSI (Abbreviated Injury Scale 3-5) between 2014 and 2021. The patients were divided into three groups based on trauma center types (adult trauma centers [ATCs], mixed trauma centers [MTCs], and pediatric trauma centers [PTCs]). The primary outcome was the splenectomy rate. Logistic regression was performed to evaluate the association between trauma center types and clinical outcomes. Additionally, the trends in the rate of splenectomy at ATCs, MTCs, and PTCs were evaluated. RESULTS: A total of 6601 patients with high-grade BSI were included in the analysis. Overall splenectomy rates were 524 (17.5%), 448 (16.3%), and 32 (3.7%) in the ATC, MTC, and PTC groups, respectively. ATCs and MTCs had significantly higher splenectomy rates compared to PTCs (ATCs: OR = 5.72, 95%CI = 3.78-8.67, and p < 0.001 and MTCs: OR = 4.50, 95%CI = 2.97-6.81, and p < 0.001), while decreased trends in the splenectomy rates were observed in ATCs and MTCs (ATCs: OR = 0.92, 95%CI = 0.87-0.97, and p = 0.003 and MTCs: OR = 0.92, 95%CI = 0.87-0.98, and p = 0.013). CONCLUSIONS: This study suggested persistent disparities between different trauma center types in the management of children with high-grade BSI.

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.

Pregnant patients undergoing cholecystectomy: nationwide assessment of clinical characteristics and outcomes.

BACKGROUND: Gallstone disease in pregnancy is one of the most common indications for nonobstetrical surgery during pregnancy. National-level data on contemporary surgical practice and outcomes are limited. OBJECTIVE: This study aimed to assess the clinical characteristics and outcomes of patients undergoing cholecystectomy during pregnancy. STUDY DESIGN: This cross-sectional study examined the Healthcare Cost and Utilization Project's 2 nationwide databases in the United States: the National Inpatient Sample and the Nationwide Ambulatory Surgery Sample. The study population included 18,630 patients who had cholecystectomy during pregnancy from January 2016 to December 2020. The exposure was gestational age, grouped sequentially into the following 5 groups: first trimester (<14 weeks), early second trimester (14-20 weeks), late second trimester (21-27 weeks), early third trimester (28-36 weeks), and late third trimester (≥37 weeks). The main outcomes were clinical demographics, medical comorbidities, surgical information, and pregnancy characteristics and outcomes, assessed by gestational age. RESULTS: Cholecystectomy was most common in the early second trimester (32.1%), followed by the first trimester (25.2%), late second trimester (23.1%), early third trimester (12.4%), and late third trimester (7.2%). Patients in the first-trimester group were more likely to be aged ≥35 years, to smoke, and to have acute cholecystitis, severe hyperemesis gravidarum including metabolic disturbance, pregestational diabetes, multifetal gestation, and sepsis/shock (P<.001). Patients in the early-third-trimester group were more likely to be obese and have gestational diabetes, Charlson Comorbidity Index of ≥1, premature rupture of membranes, and intrauterine growth restriction, whereas those in the late-third-trimester group were more likely to have gallstone pancreatitis, biliary colic, chorioamnionitis, gestational hypertension, preeclampsia, and severe maternal morbidity including sepsis (P<.001). At the cohort level, a laparoscopic approach was used in most cholecystectomy procedures (97.5%), and bile duct injury was uncommon (<0.1%). Delivery during the admission occurred in 0.3%, 0%, 0.6%, 17.8%, and 60.6% in the 5 gestational age groups, respectively (P<.001). Among the cases that had delivery in the early- and late-third-trimester groups, the delivery event preceded cholecystectomy in 61.4% and 86.2%, respectively, whereas both delivery and cholecystectomy occurred on the same day in 34.3% and 13.8%, respectively. CONCLUSION: This nationwide analysis suggests that clinical and pregnancy characteristics and outcomes of patients undergoing cholecystectomy differ by pregnancy stage with a bimodal distribution. Although patients in the first and third trimesters have distinct medical conditions, more clinically significant pregnancy and maternal outcomes were found in both groups compared with patients in the second trimester.

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.

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). METHODS: This is a retrospective observational study of the National Trauma Data Bank. We included pediatric patients (age ≤16 years) sustaining high-grade BPI (Abbreviated Injury Scale ≥3) from 2011-2021. Patients who did not undergo pancreatic operation were categorized into the non-operative 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 endoscopic retrograde cholangiopancreatography (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 [IQR]: 6-13), 64% were male, and the median injury severity score was 17 (IQR: 10-25). During the study period, there was a significant upward linear trend in the use of NOM and ERCP among the overall cohort (range 48%-66%; Ptrend =0.033, range 6.1%-19%; Ptrend =0.030, respectively). The significant upward trend for NOM was maintained in the subgroup of patients at PTC and MTC (Ptrend =0.037), while no significant trend was observed at ATC (Ptrend =0.61). There was no significant trend in in-hospital mortality (Ptrend =0.38). CONCLUSION: 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.

Association of Contrast Extravasation Grade With Massive Transfusion in Pediatric Blunt Liver and Spleen Injuries: A Multicenter Retrospective Cohort Study.

BACKGROUND: This study aimed to assess whether the grade of contrast extravasation (CE) on CT scans was associated with massive transfusion (MT) requirements in pediatric blunt liver and/or spleen injuries (BLSI). METHODS: This multicenter retrospective cohort study included pediatric patients (≤16 years old) who sustained BLSI between 2008 and 2019. MT was defined as transfusion of all blood products ≥40 mL/kg within the first 24 h of admission. Associations between CE and MT requirements were assessed using multivariate logistic regression analysis with cluster-adjusted robust standard errors to calculate the adjusted odds ratio (AOR). RESULTS: A total of 1407 children (median age: 9 years) from 83 institutions were included in the analysis. Overall, 199 patients (14 %) received MT. CT on admission revealed that 54 patients (3.8 %) had CE within the subcapsular hematoma, 100 patients (7.1 %) had intraparenchymal CE, and 86 patients (6.1 %) had CE into the peritoneal cavity among the overall cohort. Multivariate analysis, adjusted for age, sex, age-adjusted shock index, injury severity, and laboratory and imaging factors, showed that intraparenchymal CE and CE into the peritoneal cavity were significantly associated with the need for MT (AOR: 2.50; 95 % CI, 1.50-4.16 and AOR: 4.98; 95 % CI, 2.75-9.02, respectively both p < 0.001). The latter significant association persisted in the subgroup of patients with spleen and liver injuries. CONCLUSION: Active CE into the free peritoneal cavity on admission CT was independently associated with a greater probability of receiving MT in pediatric BLSI. The CE grade may help clinicians plan blood transfusion strategies. LEVEL OF EVIDENCE: Level 4; Therapeutic/Care management.

Safety/booster seats in pediatric motor vehicle crashes: Public health concern.

INTRODUCTION: The American Academy of Pediatrics (AAP) guidelines recommend that children ≤12-years-old with height < 145 cm should use safety/booster seats. However, national adherence and clinical outcomes for eligible children involved in motor vehicle collisions (MVCs) are unknown. We hypothesized that children recommended to use safety/booster seats involved in MVCs have a lower rate of serious injuries if a safety/booster seat is used, compared to children without safety/booster seat. METHODS: This retrospective cohort study queried the 2017-2019 Trauma Quality Improvement Program database for patients ≤12-years-old and <145 cm (recommendation for use of safety/booster seat per American Academy of Pediatrics) presenting after MVC. Serious injury was defined by abbreviated injury scale grade ≥3 for any body-region. High-risk MVC was defined by authors in conjunction with definitions provided by the Centers for Disease Control and Prevention and the American College of Surgeons Committee on Trauma. RESULTS: From 8259 cases, 41% used a safety/booster seat. There was no difference in overall rate of serious traumatic injuries or mortality (both p > 0.05) between the safety/booster seat and no safety/booster seat groups. In a subset analysis of high-risk MVCs, the overall use of safety/booster seats was 56%. The rate of serious traumatic injury (53.6% vs. 62.1%, p = 0.017) and operative intervention (15.8% vs. 21.6%, p = 0.039) was lower in the safety/booster seat group compared to the no safety/booster seat group. CONCLUSIONS: Despite AAP guidelines, less than half of recommended children in our study population presenting to a trauma center after MVC used safety/booster seats. Pediatric patients involved in a high-risk MVC suffered more serious injuries and were more likely to require surgical intervention without a safety/booster seat. A public health program to increase adherence to safety/booster seat use within this population appears warranted.

Propensity Score Analysis of Resuscitative Endovascular Balloon Occlusion of the Aorta: Zone-1 Versus Zone-3 Resuscitative Endovascular Balloon Occlusion of the Aorta Odds of Mortality.

INTRODUCTION: There are two zones for the placement of a Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) in trauma patients: above the mesenteric vessels (Zone-1) or below the renal arteries (Zone-3). Zone-1 REBOA diverts blood away from the visceral organs which leads to a systemic inflammatory response and reperfusion injury. We hypothesized that patients undergoing Zone-1 REBOA placement had a higher odds of mortality. METHODS: The 2017-2019 Trauma Quality Improvement Program database was queried for patients undergoing either Zone-1 or Zone-3 REBOA. We excluded all patients with prehospital cardiac arrest. We compared Zone-1 versus Zone-3 REBOA using a 1:2 propensity-score model, matching for age, mechanism, sex, hypotension, tachycardia, blunt solid organ injury grade, pelvic fracture, and injuries to the aorta, iliac artery, iliac vein, and inferior vena cava. RESULTS: We matched 130 Zone-1 REBOA patients to 260 Zone-3 REBOA patients. There were no statistically significant differences in the matched variables (P > 0.05). Compared to Zone-3 REBOA, patients with Zone-1 REBOA who survived ≥48 h had similar rates of acute kidney injury (18.6% versus 10.9%, P = 0.19). Zone-1 REBOA patients had a higher mortality rate (71.4% versus 48.8%, P = 0.002) and mortality odds ratio (OR) (OR 1.85, OR 1.18-2.89, P = 0.007). Zone-1 REBOA remained associated with a higher odds of mortality after controlling for traumatic brain injury and injury severity score (OR 1.86, OR 1.18-2.92, P = 0.007). CONCLUSIONS: Compared to Zone-3, using a REBOA in Zone-1 is associated with higher odds of mortality. The use of REBOA Zone-1 deployment should be done with caution.

Resuscitative Thoracotomy for Traumatic Cardiac Arrest: Potential Impact of Resource Constraint on Outcomes and Blood Product Utilization.

INTRODUCTION: Resuscitative thoracotomy (RT) in the setting of traumatic arrest serves as a vital but resource-intensive intervention. The COVID-19 pandemic has created critical shortages, sharpening the focus on efficient resource utilization. This study aims to compare RT performance and blood product utilization before and after the onset of the COVID-19 pandemic for patients in traumatic cardiac arrest. METHODS: All patients undergoing RT for traumatic cardiac arrest in the emergency department at our American College of Surgeons-verified Level 1 trauma center (August 01, 2017-July 31, 2022) were included in this retrospective observational study. Study groups were dichotomized into pre-COVID (before October 03, 2020) versus COVID (from October 03, 2020 on) based on patient arrival date demographics, clinical/injury data, and outcomes were collected. The primary outcome was blood product transfusion <4 h after presentation. RESULTS: 445 RTs (2% of 23,488 trauma encounters) were performed over the study period: Pre-COVID, n = 209 (2%) versus COVID, n = 236 (2%) (P = 0.697). Survival to discharge was equivalent Pre-COVID versus COVID (n = 22, 11% versus n = 21, 9%, P = 0.562). RT patients during COVID consumed a median of 1 unit less packed red blood cells at the 4 h measurement (3.0 [1.8-7.0] versus 3.9 [2.0-10.0] units, P = 0.012) and 1 unit less of platelets at the 4 h measurement (4.3 [2.6-10.0] versus 5.7 [2.9-14.4] units, P = 0.012) compared to Pre-COVID. These findings were persistent after performing multivariable negative binomial regression. CONCLUSIONS: Rates of RT and survival after RT remained consistent during the pandemic. Despite comparable RT frequency, packed red blood cells and platelet transfusions were reduced, likely reflecting resource expenditure minimization during the severe blood shortages that occurred during the pandemic. RT performance for patients in traumatic arrest may, therefore, be feasible during global pandemics at prepandemic frequencies as long as particular attention is paid to resource expenditure.

A Prospective Multicenter Comparison of Trauma and Injury Severity Score, American Society of Anesthesiologists Physical Status, and National Surgical Quality Improvement Program Calculator's Ability to Predict Operative Trauma Outcomes.

BACKGROUND: Trauma outcome prediction models have traditionally relied upon patient injury and physiologic data (eg, Trauma and Injury Severity Score [TRISS]) without accounting for comorbidities. We sought to prospectively evaluate the role of the American Society of Anesthesiologists physical status (ASA-PS) score and the National Surgical Quality Improvement Program Surgical Risk-Calculator (NSQIP-SRC), which are measurements of comorbidities, in the prediction of trauma outcomes, hypothesizing that they will improve the predictive ability for mortality, hospital length of stay (LOS), and complications compared to TRISS alone in trauma patients undergoing surgery within 24 hours. METHODS: A prospective, observational multicenter study (9/2018-2/2020) of trauma patients ≥18 years undergoing operation within 24 hours of admission was performed. Multiple logistic regression was used to create models predicting mortality utilizing the variables within TRISS, ASA-PS, and NSQIP-SRC, respectively. Linear regression was used to create models predicting LOS and negative binomial regression to create models predicting complications. RESULTS: From 4 level I trauma centers, 1213 patients were included. The Brier Score for each model predicting mortality was found to improve accuracy in the following order: 0.0370 for ASA-PS, 0.0355 for NSQIP-SRC, 0.0301 for TRISS, 0.0291 for TRISS+ASA-PS, and 0.0234 for TRISS+NSQIP-SRC. However, when comparing TRISS alone to TRISS+ASA-PS (P = .082) and TRISS+NSQIP-SRC (P = .394), there was no significant improvement in mortality prediction. NSQIP-SRC more accurately predicted both LOS and complications compared to TRISS and ASA-PS. CONCLUSIONS: TRISS predicts mortality better than ASA-PS and NSQIP-SRC in trauma patients undergoing surgery within 24 hours. The TRISS mortality predictive ability is not improved when combined with ASA-PS or NSQIP-SRC. However, NSQIP-SRC was the most accurate predictor of LOS and complications.

The Risk of Hemorrhagic Complications After Anticoagulation Therapy in Trauma Patients: A Multicenter Evaluation.

BACKGROUND: The use of anticoagulation therapy (ACT) in trauma patients during the post-injury period presents a challenge given the increased risk of hemorrhage. Guidelines regarding whether and when to initiate ACT are lacking, and as a result, practice patterns vary widely. The purpose of this study is to describe the incidence of hemorrhagic complications in patients who received ACT during their hospitalization, identify risk factors, and characterize the required interventions. METHODS: In this retrospective cohort study, all trauma admissions at two Level 1 trauma centers between January 2015 and December 2020 were reviewed. Patients with pre-existing ACT use or those who developed a new indication for ACT were included for analysis. Demographic and outcome data were collected for those who received ACT during their admission. Comparisons were then made between the complications and no complications groups. A subgroup analysis was performed for all patients started on ACT within 14 days of injury. RESULTS: A total of 812 patients were identified as having an indication for ACT, and 442 patients received ACT during the post-injury period. The overall incidence of hemorrhagic complications was 12.7%. Of those who sustained hemorrhagic complications, 18 required procedural intervention. On regression analysis, male sex, severe injuries, and the need for hemorrhage control surgery on arrival were all found to be associated with hemorrhagic complications after the initiation of ACT. Waiting 7-14 days from the time of injury to initiate ACT reduced the odds of complications by 46% and 71%, respectively. CONCLUSIONS: The use of ACT in trauma during the post-injury period is not without risk. Waiting 7-14 days post-injury might greatly reduce the risk of hemorrhagic complications. STUDY TYPE/LEVEL OF EVIDENCE: Therapeutic/care management study: Level IV.

Association Between Whole Blood Transfusion and Mortality Among Injured Pediatric Patients.

OBJECTIVE: To assess the association between whole blood (WB) and mortality among injured children who received immediate blood transfusion. BACKGROUND: The use of WB for transfusion therapy in trauma has been revisited, and recent studies have reported an association between WB and improved survival among adults. However, evidence of a similar association lacks in children. METHODS: We performed a retrospective cohort study from the ACS-TQIP between 2020 and 2021. Patients were aged ≤16 years and had immediate blood transfusion within 4 hours of hospital arrival. Survival at 24 hours and 30 days were compared after creating 1:1 propensity-score matched cohorts, matching for demographics, injury type, vital signs on admission, trauma severity scores, hemorrhage control procedures, hospital characteristics, and the need for massive transfusion. RESULTS: A total of 2,729 patients were eligible for analysis. The median age was 14 years (interquartile range: 8-16 y); 1,862 (68.2%) patients were male; and 1,207 (44.2%) patients were White. A total of 319 (11.7%) patients received WB. After a 1:1-ratio propensity score matching, 318 matched pairs were compared. WB transfusion was associated with improved survival at 24 hours, demonstrating a 42% lower risk of mortality (hazard ratio [HR], 0.58; 95% confidence interval [CI], 0.34-0.98; P =0.042) Similarly, the survival benefit associated with WB transfusion remained consistent at 30 days (HR, 0.65; 95% CI, 0.46-0.90; P =0.011). CONCLUSIONS: The use of WB was associated with improved survival among injured pediatric patients requiring immediate transfusion.

Concurrent Minimally Invasive Gynecologic Procedures at the Time of Laparoscopic Cholecystectomy.

In this cross-sectional study including 1,722,479 women who underwent laparoscopic cholecystectomy between January 2016 and December 2019 identified in the Healthcare Cost and Utilization Project's Nationwide Ambulatory Surgery Sample, the prevalence rate of gynecologic diagnoses was 11.3 per 1,000. Among presumed elective laparoscopic cholecystectomy, the highest performance rate of concurrent gynecologic procedure per gynecologic diagnosis was laparoscopic adnexectomy among patients with benign ovarian tumor (652/1,000 diagnoses), followed by laparoscopic adnexectomy for endometrioma (386/1,000 diagnoses) and cervical conization for cervical carcinoma in situ (304/1,000 diagnoses). The measured surgical morbidity rates for patients who had concurrent gynecologic surgery and those who did not were 2.8 per 1,000 and 1.9 per 1,000, respectively (adjusted odds ratio 1.39, 95% CI 0.75-2.59). These results suggest that minimally invasive gynecologic surgeries are being performed at the time of outpatient laparoscopic cholecystectomy in the United States.

Examining the independent risk factors for withdrawal of life sustaining treatment in trauma patients.

INTRODUCTION: Withdrawal of life sustaining treatment (WLST) occurs when medical intervention no longer benefits a patient's acute goals for care. The incidence of WLST in the trauma patient population is not well understood. The purpose of this study was to examine the incidence and independent risk factors associated with WLST. METHODS: The Trauma Quality Improvement Program (2017-2018) was utilized. Patients arrived without signs of life or without mortality or WLST data were excluded. Demographics, injury data, and outcomes were analyzed. Categorical variables are presented as number (percentage) and continuous variables as median [interquartile range]. WLST and non-WLST patients were compared. Early (<24 h) WLST patients were compared to all other WLST patients. RESULTS: Of 749,754 patients, 35,464 (4.7 %) died. Of these, 19,424 (2.6 %) died after WLST, constituting 54.8 % of all deaths. Median age was 67 [50-79], 67.6 % male, 17,557 (90.4 %) blunt injuries, 11,334 (58.4 %) GCS < 9. Median ISS 26 [17-30]. Median head AIS 4 (3-5). The WLST group had a much higher incidence of elderly (60+) patients (65.1% vs 41.0 %), blunt mechanism of injury (90.4% vs 76.9 %) and hypertension (43.5% vs 26.5 %). Black patients (8.2% vs 19.5 %) and Hispanic patients (7.9% vs 12.2 %) were less likely to undergo WLST. On multivariate analysis, patients 80+ years old (OR 12.939, p < 0.001), GCS < 9 (OR 15.621, p < 0.001), and head AIS = 5, head AIS = 6 (OR 3.886, p < 0.001 and OR 5.283, p < 0.001) were independently associated with WLST. GCS < 9 (OR 4.006, p < 0.001) and penetrating injury (OR 2.825, p < 0.001) were independently associated with early WLST within 24 h. CONCLUSIONS: More than half who die from trauma undergo withdrawal of life sustaining treatment. Elderly patients and those with severe TBI and low GCS scores are at high risk of experiencing withdrawal of life sustaining treatment. Further prospective evaluation is warranted.
