RESUMO
OBJECTIVE: To evaluate the optimal timing of thromboprophylaxis (TPX) initiation after hepatic angioembolization in trauma patients. SUMMARY BACKGROUND DATA: TPX after hepatic trauma is complicated by the risk of bleeding, but the relative risk after hepatic angioembolization is unknown. METHODS: Patients who underwent hepatic angioembolization within 24 hours were retrospectively identified from the 2017-19 ACS TQIP datasets. Cases with <24-hour length of stay and other serious injuries were excluded. VTE included DVT and PE. Bleeding complications included hepatic surgery, additional angioembolization, or blood transfusion after TPX initiation. Differences were tested with univariate and multivariate analyses. RESULTS: Of 1,550 patients, 1,370 had initial angioembolization. Bleeding complications were higher in those with TPX initiation within 24 hours (20.0% vs 8.9%, P<0.001) and 48 hours (13.2% vs 8.4%, P=0.013). However, VTE was higher in those with TPX initiation after 48 hours (6.3%vs 3.3%, P=0.025). In the 180 patients with hepatic surgery prior to angioembolization, bleeding complications were higher in those with TPX initiation within 24 hours (72% vs 20%, P <0.001), 48 hours (50% vs 17%, P<0.001), and 72 hours (37% vs 14%, P=0.001). Moreover, DVT was higher in those with TPX initiation after 96 hours (14.3% vs 3.1%, P =0.023). CONCLUSION: This is the first study to address timing of TPX after hepatic angioembolization in a national sample of trauma patients. For these patients, initiation of TPX at 48- 72 hours achieves the safest balance in minimizing bleeding while reducing the risk of VTE. LEVEL OF EVIDENCE: Level III - Retrospective Cohort Study.
RESUMO
INTRODUCTION: Ballistic injuries cause both a temporary and permanent cavitation event, making them far more destructive and complex than other penetrating trauma. We hypothesized that global injury scoring and physiologic parameters would fail to capture the lethality of gunshot wounds (GSW) compared to other penetrating mechanisms. METHODS: The 2019 American College of Surgeons Trauma Quality Programs participant use file was queried for the mortality rate for GSW and other penetrating mechanisms. A binomial logistic regression model ascertained the effects of sex, age, hypotension, tachycardia, mechanism, Glasgow Coma Scale, ISS, and volume of blood transfusion on the likelihood of mortality. Subgroup analyses examined isolated injuries by body regions. RESULTS: Among 95,458 cases (82% male), GSW comprised 46.4% of penetrating traumas. GSW was associated with longer hospital length of stay (4 [2-9] versus 3 [2-5] days), longer intensive care unit length of stay (3 [2-6] versus 2 [2-4] days), and more ventilator days (2 [1-4] versus 2 [1-3]) compared to stab wounds, all P < 0.001. The model determined that GSW was linked to increased odds of mortality compared to stab wounds (odds ratio 4.19, 95% confidence interval 3.55-4.93). GSW was an independent risk factor for acute kidney injury, acute respiratory distress syndrome, venous thromboembolism, sepsis, and surgical site infection. CONCLUSIONS: Injury scoring systems based on anatomical or physiological derangements fail to capture the lethality of GSW compared to other mechanisms of penetrating injury. Adjustments in risk stratification and reporting are necessary to reflect the proportion of GSW seen at each trauma center. Improved classification may help providers develop quality processes of care. This information may also help shape public discourse on this highly lethal mechanism.

INTRODUCTION: Relative to other hospitalized patients, trauma patients are younger with fewer comorbidities, but the incidence and outcomes of in-hospital cardiopulmonary arrest (IHCA) with cardiopulmonary resuscitation (CPR) in this population is unknown. Therefore, we aimed to investigate factors associated with survival in trauma patients after IHCA to test the hypothesis that compared to other hospitalized patients, trauma patients with IHCA have improved survival. METHODS: Retrospective review of the Trauma Quality Improvement Program database 2017 to 2019 for patients who had IHCA with CPR. Primary outcome was survival to hospital discharge. Secondary outcomes were in-hospital complications, hospital length of stay, intensive care unit length of stay, and ventilator days. Data were compared with univariate and multivariate analyses at P < 0.05. RESULTS: In 22,346,677 admitted trauma patients, 14,056 (0.6%) received CPR. Four thousand three hundred seventy-seven (31.1%) survived to discharge versus 26.4% in a national sample of all hospitalized patients (P < 0.001). In trauma patients, median age was 55 y, the majority were male (72.2%). Mortality was higher for females versus males (70.3% versus 68.3%, P = 0.026). Multivariate regression showed that older age 1.01 (95% confidence interval (CI) 1.01-1.02), Hispanic ethnicity 1.21 (95% CI 1.04-1.40), and penetrating trauma 1.51 (95% CI 1.32-1.72) were risk factors for mortality, while White race was a protective factor 0.36 (95% CI 0.14-0.89). CONCLUSIONS: This is the first study to show that the incidence of IHCA with CPR is approximately six in 1000 trauma admissions and 31% survive to hospital discharge, which is higher than other hospitalized patients. Age, gender, racial, and ethnic disparities also influence survival.

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.

INTRODUCTION: We aim to study the association between state child access prevention (CAP) and overall firearm laws with pediatric firearm-related mortality. METHODS: The Centers for Disease Control and Prevention Web-based Injury Statistics Query and Reporting System was queried for pediatric (aged < 18 y) all-intent (accidental, suicide, and homicide) firearm-related crude death rates (CDRs) among the 50 states from 1999 to 2019. States were into three groups: Always CAP (throughout the 20-year period), Never CAP, and New CAP (enacted CAP during study period). We used the Giffords Law Center Annual Gun Law Scorecard (A, B, C, D, F) to group states into strict (A, B) and lenient (C, D, F) firearm laws. A scatter plot was constructed to display state CDR based on CAP laws by year. The top 10 states by CDR per year were tabulated based on CAP law status. Wilcoxon rank-sum was used to compare CDR between strict and lenient scorecard states in 2019. RESULTS: There were 12 Always CAP, 21 Never CAP, and 17 New CAP states from 1999 to 2019. No states changed from CAP laws to no CAP laws. Never CAP and New CAP states dominated the high outliers in CDR compared to Always CAP. The top 10 states with the highest CDR per year were most commonly Never CAP. Strict firearm laws states had lower median CDR in 2019 than lenient states (0.79 [0-1.67] versus 2.59 [1.66-3.53], P = 0.007). CONCLUSIONS: Stricter overall gun laws are associated with three-fold lower all-intent pediatric firearm-related deaths. For 2 decades, the 10 states with the highest CDR were almost universally those without CAP laws. Our findings support the RAND Gun Policy in America initiative's claims on the importance of CAP laws in reducing suicide, unintentional deaths, and violent crime among children, but more research is needed.

BACKGROUND: There are significant practice variations in antibiotic treatment for appendicitis, ranging from short-course narrow spectrum to long-course broad-spectrum. We sought to describe the modern microbial epidemiology of acute and perforated appendicitis in adults to help inform appropriate empiric coverage and support antibiotic stewardship initiatives. METHODS: This is a post-hoc secondary analysis of the Multicenter Study of the Treatment of Appendicitis in America: Acute, Perforated, and Gangrenous (MUSTANG) which prospectively enrolled adult patients (age ≥ 18 years) diagnosed with appendicitis between January 2017 and June 2018 across 28 centers in the United States. We included all subjects with positive microbiologic cultures during primary or secondary (rescue after medical failure) appendectomy or percutaneous drainage. Culture yield was compared between low- and high-grade appendicitis as per the AAST classification. RESULTS: A total of 3,471 patients were included: 230 (7%) had cultures performed, and 179/230 (78%) had positive results. Cultures were less likely to be positive in grade 1 compared to grades 3, 4, or 5 appendicitis with 2/18 (11%) vs 61/70 (87%) (p < .001). Only 1 subject had grade 2 appendicitis and culture results were negative. E. coli was the most common pathogen and cultured in 29 (46%) of primary appendectomy samples, 16 (50%) of secondary, and 44 (52%) of percutaneous drainage samples. CONCLUSION: Culturing low-grade appendicitis is low yield. E. coli is the most commonly cultured microbe in acute and perforated appendicitis. This data helps inform empiric coverage for both antibiotics alone and as an adjunct to operative or percutaneous intervention.

BACKGROUND: The American Association for the Surgery of Trauma (AAST) appendicitis severity grading criteria use independent subscales for radiologists (Rad), surgeons (Surg), and pathologists (Path). We reviewed the EAST Multicenter Study of the Treatment of Appendicitis in America: Acute, Perforated, and Gangrenous (MUSTANG) database to determine rates of discordance and clinical consequences of inaccuracy. MATERIALS AND METHODS: A confusion matrix was constructed for pairs among Rad, Surg, and Path. Accuracy was reported using chronologically latest diagnosis as gold standard. "Concordance" (C) was achieved when both agreed on the severity grade and "Discordance"(D) when they disagreed. A composite endpoint("COMP"= 30-d incidence of surgical site infection, abscess, wound complication, Clavien-Dindo complication, secondary intervention, ED[Emergency Department] visit, hospital readmission, and mortality) was compared between C versus D groups via χ2 test with Bonferroni correction to define statistical significance(P = 0.05/9 = 0.005). RESULTS: For each pair and diagnosis, subjects were categorized as C or D and compared for the incidence of COMP. Incidence of COMP for Surg and/or Path in C versus D: 16% versus. 26% (p = 0.006, NS by Bonferroni) for acute (A), 39% versus 33% (p = 0.39) for gangrenous (G), and 48% versus 37% (p = 0.035, NS by Bonferroni) for perforated (P). For Rad and/or Path in C versus. D: 17% versus 42% (p < 0.001) for A, 27% versus 31% (p = 0.95) for G, and 56% versus 48% (p = 0.48) for P. For C versus D: 17% versus 40% (p < 0.001) for A, 36% versus 26% (p = 0.43) for G, and 51% versus 39% (p = 0.29) for P. CONCLUSIONS: In appendicitis treated by appendectomy, surgeons are most accurate at diagnosing acute appendicitis and least accurate at diagnosing gangrenous. Radiologists are less accurate for all categories. When the surgeon is wrong, clinical outcomes are not significantly worse. However, when the radiologist is wrong about acute appendicitis, patients have worse clinical outcomes.

OBJECTIVE: Inferior vena cava (IVC) injuries have a high mortality rate that may be related to the location of injury and type of repair. Previous studies have been either single center series or database studies lacking granular detail. These have reported conflicting results. We aimed to perform a systematic review and meta-analysis of published literature evaluating ligation versus repair. METHODS: Studies published in English on MEDLINE or EMBASE from 1946 through October 2018 were examined to evaluate mortality among patients treated with ligation versus repair of IVC injuries. Studies were included if they provided mortality associated with ligation versus repair and reported IVC injury by level. Risk of bias was assessed regarding incomplete and selective outcome reporting with Newcastle-Ottawa score of 7 or higher to evaluate study quality. We used a random-effects model with restricted maximum likelihood estimation method in R using the Metafor package to evaluate outcomes. RESULTS: Our systematic review identified 26 studies, of which 14 studies, including 855 patients, met our inclusion criteria for meta-analysis. IVC ligation was associated with higher mortality than IVC repair (OR: 3.12, P < 0.01, I2â¯=â¯49%). Ligation of infrarenal IVC injuries was not statistically associated with mortality (OR: 3.13, Pâ¯=â¯0.09). Suprarenal injury location compared to infrarenal (OR 3.11, P < 0.01, I2â¯=â¯28%) and blunt mechanism compared to penetrating (OR: 1.91, Pâ¯=â¯0.02, I2â¯=â¯0%) were also associated with higher mortality. CONCLUSIONS: In this meta-analysis, ligation of IVC injuries was associated with increased mortality compared to repair, but not specifically for infrarenal IVC injuries. Suprarenal IVC injury, and blunt mechanism was associated with increased mortality compared to infrarenal IVC injury and penetrating mechanism, respectively. Data are limited regarding acute renal injury and venous thromboembolic events after IVC ligation and may warrant multicenter studies. Standardized reporting of IVC injury data has not been well established and is needed in order to enable comparison of outcomes across institutions. In particular, reporting of injury location, severity, and repair type should be standardized. A contemporary prospective, multicenter study is needed in order to definitively compare surgical technique.

BACKGROUND: In trauma patients, the recognition of fibrinolysis phenotypes has led to a re-evaluation of the risks and benefits of antifibrinolytic therapy (AF). Many cardiac patients also receive AF, but the distribution of fibrinolytic phenotypes in that population is unknown. The purpose of this hypothesis-generating study was to fill that gap. METHODS: Seventy-eight cardiac surgery patients were retrospectively reviewed. Phenotypes were defined as hypofibrinolytic (LY30 <0.8%), physiologic (0.8%-3.0%), and hyperfibrinolytic (>3%) based on thromboelastogram. RESULTS: The population was 65 ± 10-years old, 74% male, average body mass index of 29 ± 5 kg/m2 . Fibrinolytic phenotypes were distributed as physiologic = 45% (35 of 78), hypo = 32% (25 of 78), and hyper = 23% (18 of 78). There was no obvious effect of age, gender, race, or ethnicity on this distribution; 47% received AF. For AF versus no AF, the time with chest tube was longer (4 [1] vs. 3 [1] days, p = .037), and all-cause morbidity was more prevalent (51% vs. 25%, p = .017). However, when these two groups were further stratified by phenotypes, there were within-group differences in the percentage of patients with congestive heart failure (p = .022), valve disease (p = .024), on-pump surgery (p < .0001), estimated blood loss during surgery (p = .015), transfusion requirement (p = .015), and chest tube output (p = .008), which highlight other factors along with AF that might have affected all-cause morbidity. CONCLUSION: This is the first description of the prevalence of three different fibrinolytic phenotypes and their potential influence on cardiac surgery patients. The use of AF was associated with increased morbidity, but because of the small sample size and treatment allocation bias, additional confirmatory studies are necessary. We hope these present findings open the dialog on whether it is safe to administer AFs to cardiac surgery patients who are normo- or hypofibrinolytic.

BACKGROUND: Previous studies have shown that a notable portion of patients who are readmitted for reinjury after penetrating trauma present to a different hospital. The purpose of this study was to identify the risk factors for reinjury after penetrating trauma including reinjury admissions to different hospitals. METHODS: The 2010-2014 Nationwide Readmissions Database was queried for patients surviving penetrating trauma. E-codes identified patients subsequently admitted with a new diagnosis of blunt or penetrating trauma. Univariable analysis was performed using 44 injury, patient, and hospital characteristics. Multivariable logistic regression using significant variables identified risk factors for the outcomes of reinjury, different hospital readmission, and in-hospital mortality after reinjury. RESULTS: There were 443,113 patients identified. The reinjury rate was 3.5%. Patients presented to a different hospital in 30.0% of reinjuries. Self-inflicted injuries had a higher risk of reinjury (odds ratio [OR]: 2.66, P < 0.05). Readmission to a different hospital increased risk of mortality (OR: 1.62, P < 0.05). Firearm injury on index admission increased risk of mortality after reinjury (OR: 1.94, P < 0.05). CONCLUSIONS: This study represents the first national finding that one in three patients present to a different hospital for reinjury after penetrating trauma and have a higher risk of mortality due to this fragmentation of care. These findings have implications for quality and cost improvements by identifying areas to improve continuity of care and the implementation of penetrating injury prevention programs.

BACKGROUND: The Advanced Trauma Life Support (ATLS) shock classification has been accepted as the conceptual framework for clinicians caring for trauma patients. We sought to validate its ability to predict mortality, blood transfusion, and urgent intervention. MATERIALS AND METHODS: We performed a retrospective review of trauma patients using the 2014 National Trauma Data Bank. Using initial vital signs data, patients were categorized into shock class based on the ATLS program. Rates for urgent blood transfusion, urgent operative intervention, and mortality were compared between classes. RESULTS: 630,635 subjects were included for analysis. Classes 1, 2, 3, and 4 included 312,404, 17,133, 31, and 43 patients, respectively. 300,754 patients did not meet criteria for any ATLS shock class. Of the patients in class 1 shock, 2653 died (0.9%), 3123 (1.0%) were transfused blood products, and 7115 (2.3%) underwent an urgent procedure. In class 2, 219 (1.3%) died, 387 (2.3%) were transfused, and 1575 (9.2%) underwent intervention. In class 3, 7 (22.6%) died, 10 (32.3%) were transfused, and 13 (41.9%) underwent intervention. In class 4, 15 (34.9%) died, 19 (44.2%) were transfused, and 23 (53.5%) underwent intervention. For uncategorized patients, 21,356 (7.1%) died, 15,168 (5.0%) were transfused, and 23,844 (7.9%) underwent intervention. CONCLUSIONS: Almost half of trauma patients do not meet criteria for any ATLS shock class. Uncategorized patients had a higher mortality (7.1%) than patients in classes 1 and 2 (0.9% and 1.3%, respectively). Classes 3 and 4 only accounted for 0.005% and 0.007%, respectively, of patients. The ATLS classification system does not help identify many patients in severe shock.

BACKGROUND: We sought to compare the effectiveness of narrow- versus broad-spectrum antibiotics (abx) in preventing infectious complications in adults with acute appendicitis treated with appendectomy. METHODS: In this post hoc analysis of a prospective multicenter observational study of appendicitis in adults (≥18 y) conducted from January 2017 to June 2018, we included only patients with simple appendicitis. Subjects were grouped based on receipt of broad-spectrum or narrow-spectrum abx before and/or after appendectomy. Outcomes compared were surgical site infection, intra-abdominal abscess, secondary interventions (percutaneous drainage or operation), emergency department (ED) visits, 30-d readmission, and hospital length of stay. RESULTS: A total of 2336 subjects were analyzed. In comparing narrow (n = 778) versus broad (n = 1558) groups, there were no differences in male sex (53% versus 54%, P = 0.704), white blood cell (13.0 ± 3.9 versus 13.4 ± 4.5, P = 0.05), Alvarado score (6 [5-7] versus 6 [5-7], P = 0.25), or Charlson comorbidity index (0 [0-1] versus 0 [0-1], P = 0.09). A total of 688 (29%) received postoperative abx, [184 (24%) narrow and 504 (32%) broad, P < 0.001] for a median 5 [2-7] d [42 (23%) narrow and 235 (47%) broad, P < 0.001]. There were no significant differences between narrow and broad groups in surgical site infection, intra-abdominal abscess, secondary interventions, ED visits, or hospital readmissions. CONCLUSIONS: Significant practice variation in duration and spectrum of antibiotic adjunct for surgical treatment of simple acute appendicitis treatment is evident, and broad-spectrum abx did not offer clinical advantages over narrow-spectrum abx. Restriction of antibiotic spectrum should be considered, although randomized trials are required to overcome selection bias.

BACKGROUND: Historically, carotid procedures incur a readmission rate of approximately 6%; however, these studies are not nationally representative and are limited to tracking only the index hospitals. We sought to evaluate a nationally representative database for readmission rates (including different hospitals) after both carotid endarterectomy (CEA) and carotid artery stenting (CAS) and determine risk factors for poor outcomes including postoperative mortality and myocardial infarction. METHODS: This study was a retrospective analysis utilizing the 2010-2014 Nationwide Readmissions Database to query patients aged >18 years undergoing CEA or CAS. Outcomes included initial admission mortality, and 30-day readmission, including mortality and myocardial infarction (MI). Univariable analysis of 39 demographic, clinical, and hospital variables was conducted with significance set at P < 0.05. Significant variables were included in a multivariable logistic regression to identify independent risk factors for readmission. Results were weighted for national estimates. RESULTS: There were 527,622 patients undergoing carotid procedures and 13% (n = 69,187) underwent CAS. The 30-day readmission rate was 7% (n = 35,782), and of those, 25% (n = 8,862) were readmitted to a different hospital. When controlling for other factors, CAS was a risk factor for mortality at both index admission (odds ratio [OR] 2.29 [2.11-2.49]) and 30-day readmission (OR 1.48 [1.3-1.69]) and 30-day readmissions at both index hospital (OR 1.11 [1.07-1.14]) and different hospital (OR 1.38 [1.29-1.48]). Readmission to a different hospital increased mortality risk (OR 1.45 [1.29-1.63]) but did not have an effect on MI. Postoperative infections comprised 15% of readmissions while 6% of all readmissions were for stroke. CONCLUSIONS: Previously unreported, one in 4 readmissions after carotid procedures occur at a different hospital and this fragmentation of care could increase mortality risk after carotid procedures particularly for CAS which was also an independent risk factor for postoperative mortality and readmissions. Further validation is required to decrease unnecessary hospital after carotid procedures.

BACKGROUND: It is commonly taught that a widened mediastinum (WM) on chest X-ray (CXR) is a marker for aortic injury (AI). We sought to describe the epidemiology of injuries for all patients with WM and compare their CXR to those of patients with confirmed AI. METHODS: Adults (age ≥ 18) sustaining blunt traumatic injuries from January 2017 to June 2017 with both CXR (supine, anterior-posterior) and chest CT were included. We excluded those whose CT preceded CXR and those with missing data. Basic demographics, injury characteristics, mediastinal width (MW), mediastinal-to-thoracic width ratio (MTR), and all thoracic imaging findings were analyzed. MW > 8 cm was considered WM. We also queried our registry for all AI patients over a 4-year period. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of WM on CXR for AI were calculated. Multivariate logistic regression was performed to identify factors associated with positive traumatic findings, controlling for body mass index (BMI), sex, high-energy mechanism, MTR, and mediastinal width. RESULTS: Of 749 included subjects, 502 (67%) had an MW > 8 cm: mean age was 48 ± 20 y, 381 (76%) were men, and BMI was 28 ± 5 kg/m2. Mechanism of injury was motor vehicle crash in 335 (67%); fall in 113 (23%); assault in 31 (6%); other (jet-ski accidents, etc.) in 17 (3%), and unknown in 6 (1%). Only 128 (26%) of patients with WM had positive findings on CT, with the most common [80 (16%)] being nontraumatic findings (pericardial infusion, lymph nodes, etc.), followed by hemomediastinum/pneumomediastinum [32 (6%)], sternal fractures [18 (4%)], multiple findings [15 (3%)], and vertebral fractures [6 (1%)]. Only 2 (1%) had AI. The sensitivity was 100%, specificity was 33%, PPV was 0.4%, NPV was 100%, and accuracy was 33%. From 2013 to 2017, 38 patients had AI: mean age was 46 ± 19 y, 26 (68%) were men, and BMI was 28 ± 4 kg/m2. Motor vehicle crash was the most common mechanism (89%), followed by "other" trauma mechanism (5%), fall (3%), and assault (3%). On univariate analysis, compared with all patients with WM, patients with AI had significantly greater MW (9.5 [8.8-10.4] versus 10.2 [9.1-11.1]; P = 0.042) and MTR (0.31 [0.28-0.34] versus 0.32 [0.31-0.37]; P = 0.001), although the actual differences were not clinically significant. The regression analysis did not identify any factors associated with traumatic CXR findings. CONCLUSIONS: Most bluntly injured adults have a WM, and the majority have either no findings or nontraumatic findings. The PPV of a WM for AI is <1%. WM on supine CXR is nonspecific and inaccurate for diagnosing traumatic injuries, especially AI.

BACKGROUND: Pediatric pelvic fractures are rare. The contribution of pelvic fracture pattern, risk factors for associated injuries, and mortality are poorly defined in this population. METHODS: Patients aged 0-17 with pelvic fractures at a level I trauma center over a 20-y period were reviewed. Fracture patterns were classified according to the Young-Burgess classification when applicable. Fractures were analyzed for location, pubic symphysis or sacroiliac widening, and contrast extravasation. RESULTS: There were 163 pelvic fractures in 8758 admissions (incidence 2%). The most common associated injures were extremity fractures (60%, n = 98), abdominal solid organ (55%, n = 89), and chest (48%, n = 78), with the majority (61%, n = 99) sustaining injuries to multiple organs. Unstable fractures were associated with injures to the thorax (70% versus 40%), heart (15% versus 2%), and spleen (40% versus 18%), all P < 0.05. Nonpelvic operative interventions were required in 45% (n = 73) and were more common in unstable fractures (36% versus 19%), contrast extravasation (63% versus 26%), sacroiliac widening (36% versus 20%), and sacral fractures (39% versus 13%), all P < 0.05. Mortality was 13% and higher in males versus females (18% versus 5%), contrast extravasation (50% versus 3%), or sacroiliac/pubic symphysis widening (13% versus 2%) (all P < 0.05). Male gender (OR 6.03), brain injury (OR 6.18), spine injury (OR 5.06), and cardiac injury (OR 35.0) were independently associated with mortality (all P < 0.05). CONCLUSIONS: Pediatric pelvic fractures are rare but critical injuries associated with significant morbidity and need for interventions. Increasing fracture severity corresponds to injuries to other body systems and increased mortality.

BACKGROUND: Augmented renal clearance (ARC; i.e., creatinine clearance [CLCr] ≥ 130 mL/min) has an incidence of 14%-80% in critically ill patients and has been associated with therapy failures for renally cleared drugs. However, the clinical implications of ARC are poorly defined. We hypothesize that modifiable risk factors that contribute to ARC can be identified in severely injured trauma patients and that these risk factors influence clinical outcome. METHODS: In 207 trauma intensive care unit patients, 24-h CLCr was correlated with clinical estimates of glomerular filtration rate (by Cockroft-Gault, modification of diet in renal disease, or chronic kidney disease epidemiology), and clinical outcomes (infection, venous thromboembolism [VTE], length of stay, and mortality). RESULTS: The population was 45 ± 20 y, 68% male, 77% blunt injury with injury severity score of 24 (17-30). Admission serum creatinine was 1.02 ± 0.35 mg/dL, CLCr was 154 ± 77 mL/min, VTE incidence was 15%, ARC incidence was 57%, and mortality was 11%. Clinical estimates of glomerular filtration rate by Cockroft-Gault, modification of diet in renal disease, chronic kidney disease epidemiology underestimated actual CLCr by 20%, 22%, or 15% (all P < 0.01). CLCr was higher in males and those who survived, and lower in those with hypertension, diabetes, positive cultures, receiving transfusions, or pressors (all P < 0.05). On multivariate analysis, male gender (odds ratio [OR] 2.9 [1.4-6.1]), age (OR 0.97 [0.95-0.99]), and packed red blood cells transfusion (OR 0.31 [0.15-0.66]) were the only independent predictors of ARC. CONCLUSIONS: ARC occurs in more than half of all high-risk trauma intensive care unit patients and is underestimated by standard clinical equations. ARC was not associated with increased incidence of VTE or infection but rather is associated with younger healthier males and reduced mortality. ARC seems to be a beneficial compensatory response to trauma.

Pancreas transplant achieves consistent long-term euglycemia in type 1 diabetes. Allograft thrombosis (AT) causes the majority of early graft failure. We compared outcomes of four anticoagulation regimens administered to 95 simultaneous kidney-pancreas or isolated pancreas transplanted between 1/1/2015 and 11/20/2018. Early postoperative anticoagulation regimens included the following: none, subcutaneous heparin/aspirin, with or without dextran, and heparin infusion. The regimens were empirically selected based on each surgeon's assessment of hemostasis of the operative field and personal preference. A sonographic-based global scoring system of AT is presented. The 47-month recipients and graft survival were 95% and 86%, respectively. Recipients with or without AT had similar survival. Five and four grafts were lost due to death and AT, respectively. Outcomes of prophylaxis regimens correlated with intensity of anticoagulation. Compared with no anticoagulation, an increase in hemorrhagic complications occurred exclusively with iv heparin. The higher arterial AT score found in regimens lacking antiplatelet therapy highlights the importance of early antiaggregants therapy. Abnormal fibrinolysis was associated with an increase in AT score. Platelet dysfunction, warm ischemia time, and enteric drainage were predictive of AT and, along with other known risk factors, were incorporated into an algorithm that matches intensity of early postoperative anticoagulation to the thrombotic risk.

OBJECTIVE: To compare the risk factors and costs associated with readmission after firearm injury nationally, including different hospitals. BACKGROUND: No national studies capture readmission to different hospitals after firearm injury. METHODS: The 2013 to 2014 Nationwide Readmissions Database was queried for patients admitted after firearm injury. Logistic regression identified risk factors for 30-day same and different hospital readmission. Cost was calculated. Survey weights were used for national estimates. RESULTS: There were 45,462 patients admitted for firearm injury during the study period. The readmission rate was 7.6%, and among those, 16.8% were readmitted to a different hospital. Admission cost was $1.45 billion and 1-year readmission cost was $131 million. Sixty-four per cent of those injured by firearms were publicly insured or uninsured. Readmission predictors included: length of stay >7 days [odds ratio (OR) 1.43, P < 0.01], Injury Severity Score >15 (OR 1.41, P < 0.01), and requiring an operation (OR 1.40, P < 0.01). Private insurance was a predictor against readmission (OR 0.81, P < 0.01). Predictors of readmission to a different hospital were unique and included: initial admission to a for-profit hospital (OR 1.52, P < 0.01) and median household income ≥$64,000 (OR 1.48, P < 0.01). CONCLUSIONS: A significant proportion of the national burden of firearm readmissions is missed by not tracking different hospital readmission and its unique set of risk factors. Firearm injury-related hospitalization costs $791 million yearly, with the largest fraction paid by the public. This has implications for policy, benchmarking, quality, and resource allocation.

BACKGROUND: The successful treatment of intraabdominal infection requires a combination of anatomical source control and antibiotics. The appropriate duration of antimicrobial therapy remains unclear. METHODS: We randomly assigned 518 patients with complicated intraabdominal infection and adequate source control to receive antibiotics until 2 days after the resolution of fever, leukocytosis, and ileus, with a maximum of 10 days of therapy (control group), or to receive a fixed course of antibiotics (experimental group) for 4±1 calendar days. The primary outcome was a composite of surgical-site infection, recurrent intraabdominal infection, or death within 30 days after the index source-control procedure, according to treatment group. Secondary outcomes included the duration of therapy and rates of subsequent infections. RESULTS: Surgical-site infection, recurrent intraabdominal infection, or death occurred in 56 of 257 patients in the experimental group (21.8%), as compared with 58 of 260 patients in the control group (22.3%) (absolute difference, -0.5 percentage point; 95% confidence interval [CI], -7.0 to 8.0; P=0.92). The median duration of antibiotic therapy was 4.0 days (interquartile range, 4.0 to 5.0) in the experimental group, as compared with 8.0 days (interquartile range, 5.0 to 10.0) in the control group (absolute difference, -4.0 days; 95% CI, -4.7 to -3.3; P<0.001). No significant between-group differences were found in the individual rates of the components of the primary outcome or in other secondary outcomes. CONCLUSIONS: In patients with intraabdominal infections who had undergone an adequate source-control procedure, the outcomes after fixed-duration antibiotic therapy (approximately 4 days) were similar to those after a longer course of antibiotics (approximately 8 days) that extended until after the resolution of physiological abnormalities.

Desirability of outcome ranking and response adjusted for duration of antibiotic risk (DOOR/RADAR) are novel and innovative methods of evaluating data in antibiotic trials. We analyzed data from a noninferiority trial of short-course antimicrobial therapy for intra-abdominal infection (STOP-IT), and results suggest global superiority of short-duration therapy for intra-abdominal infections.
