What Is Going on in Our Schools? Review of Injuries Among School Children Across the United States.

INTRODUCTION: Children spend most of their time at school and participate in many activities that have the potential for causing injury. This study aims to describe the nationwide epidemiology of pediatric trauma sustained in school settings in the United States. METHODS: In the 3-y analysis of 2017-2019 American College of Surgeons-Trauma Quality Program, all pediatric trauma patients (≤18 y) injured in a school setting were included and stratified based on place of injury, into elementary, middle, and high school (HS) groups. Descriptive statistics and multivariable logistic regression analysis were performed to identify the independent predictors of intentional injuries. RESULTS: 23,215 pediatric patients were identified, of which 15,264 patients were injured at elementary (57.6%), middle (17.5%), and high (25%) schools. The mean age was 9.5 y, 66.9% were male, 63.9% were white, the median injury severity score was 2 [1-4], and 95.6% had a blunt injury. Elementary school students were more likely to sustain falls (85%) and humerus fractures (43%) whereas HS students were more likely to be injured by assaults (17%). Overall, 7% of the students sustained intentional injuries. On multivariable logistic regression, male gender (odds ratio [OR] 1.54), Black race (OR 2.94), American Indian race (OR 1.88), Hispanic ethnicity (OR 1.77), positive drug screen (OR 4.9), middle (OR 5.2), and HSs (OR 10.6) were identified as independent predictors of intentional injury (all P < 0.01). CONCLUSIONS: Injury patterns vary across elementary, middle, and HSs. Racial factors appear to influence intentional injuries along with substance abuse. Further studies to understand these risk factors and efforts to reduce school injuries are warranted to provide a safe learning environment for children.

Maximizing wound coverage in full-thickness skin defects: A randomized-controlled trial of autologous skin cell suspension and widely meshed autograft versus standard autografting.

BACKGROUND: Traumatic insults, infection, and surgical procedures can leave skin defects that are not amenable to primary closure. Split-thickness skin grafting (STSG) is frequently used to achieve closure of these wounds. Although effective, STSG can be associated with donor site morbidity, compounding the burden of illness in patients undergoing soft tissue reconstruction procedures. With an expansion ratio of 1:80, autologous skin cell suspension (ASCS) has been demonstrated to significantly decrease donor skin requirements compared with traditional STSG in burn injuries. We hypothesized that the clinical performance of ASCS would be similar for soft tissue reconstruction of nonburn wounds. METHODS: A multicenter, within-patient, evaluator-blinded, randomized-controlled trial was conducted of 65 patients with acute, nonthermal, full-thickness skin defects requiring autografting. For each patient, two treatment areas were randomly assigned to concurrently receive a predefined standard-of-care meshed STSG (control) or ASCS + more widely meshed STSG (ASCS+STSG). Coprimary endpoints were noninferiority of ASCS+STSG for complete treatment area closure by Week 8, and superiority for relative reduction in donor skin area. RESULTS: At 8 weeks, complete closure was observed for 58% of control areas compared with 65% of ASCS+STSG areas (p = 0.005), establishing noninferiority of ASCS+STSG. On average, 27.4% less donor skin was required with ASCS+ STSG, establishing superiority over control (p < 0.001). Clinical healing (≥95% reepithelialization) was achieved in 87% and 85% of Control and ASCS+STSG areas, respectively, at 8 weeks. The treatment approaches had similar long-term scarring outcomes and safety profiles, with no unanticipated events and no serious ASCS device-related events. CONCLUSION: ASCS+STSG represents a clinically effective and safe solution to reduce the amount of skin required to achieve definitive closure of full-thickness defects without compromising healing, scarring, or safety outcomes. This can lead to reduced donor site morbidity and potentially decreased cost associated with patient care.Clincaltrials.gov identifier: NCT04091672.

Local Antibiotic Therapy for Open Long Bone Fractures: Appropriate Prophylaxis or Unnecessary Exposure for the Orthopedic Trauma Patient?

INTRODUCTION: Prophylactic local antibiotic therapy (LAbT) to prevent infection in open long bone fracture (OLBF) patients has been in use for many decades despite lack of definitive evidence confirming a beneficial effect. We aimed to evaluate the effect of LAbT on outcomes of OLBF patients on a nationwide scale. MATERIALS AND METHODS: In this retrospective analysis of 2017-2018 American College of Surgeons-Trauma Quality Improvement Program database, all adult (≥18 years) patients with isolated OLBF (non-extremity-Abbreviated Injury Scale < 3) were included. We excluded early deaths (<24 h) and those who had burns or non-extremity surgery. Outcomes were infectious complications (superficial surgical site infection, deep superficial surgical site infection, osteomyelitis, or sepsis), unplanned return to operating room, and hospital and intensive care unit length of stay (LOS). Patients were stratified into two groups: those who received LAbT and those who did not receive LAbT (No-LAbT). Propensity score matching (1:3) and chi-square tests were performed. RESULTS: A total of 61,337 isolated OLBF patients were identified, among whom 2,304 patients were matched (LAbT: 576; No-LAbT: 1,728). Both groups were similar in terms of baseline characteristics. Mean age was 43 ± 17 years, 75% were male, 14% had penetrating injuries, and the median extremity-Abbreviated Injury Scale was 1 (1-2). Most common fracture locations were tibia (66%), fibula (49%), femur (24%), and ulna (11%). About 52% of patients underwent external fixation, 79% underwent internal fixation, and 86% underwent surgical debridement. The median time to LAbT was 17 (5-72) h, and the median time to debridement was 7 (3-15) h (85% within 24 h). The LAbT group had similar rates of infectious complications (3.5% vs. 2.5%, P = 0.24) and unplanned return to the operating room (2.3% vs. 2.0%, P = 0.74) compared to the No-LAbT group. Patients who received LAbT had longer hospital LOS (16 [10-29] vs. 14 [9-24] days, P < 0.001) but similar intensive care unit LOS (4 [3-9] vs. 4 [2-7] days, P = 0.19). CONCLUSIONS: Our findings indicate that prophylactic LAbT for OLBF may not be beneficial over well-established standards of care such as early surgical debridement and systemic antibiotics. Prospective studies evaluating the efficacy, risks, costs, and indications of adjuvant LAbT for OLBF are warranted.

Emergency Department Shock Index Outperforms Prehospital and Delta Shock Indices in Predicting Outcomes of Trauma Patients.

INTRODUCTION: Multiple shock indices (SIs), including prehospital, emergency department (ED), and delta (ED SI - Prehospital SI) have been developed to predict outcomes among trauma patients. This study aims to compare the predictive abilities of these SIs for outcomes of polytrauma patients on a national level. METHODS: This was a retrospective analysis of the American College of Surgeons Trauma Quality Improvement Program (2017-2018). We included adult (≥18 y) trauma patients and excluded patients who were transferred, had missing vital signs, and those with severe head injuries (Head-Abbreviated Injury Scale>3). Outcome measures were 24-h and in-hospital mortality, 24-h packed red blood cells transfusions, and intensive care unit and hospital length of stay. Predictive performances of these SIs were evaluated by the Area Under the Receiver Operating Characteristics for the entire study cohort and across all injury severities. RESULTS: A total of 750,407 patients were identified. Meanstandard deviation age and lowest systolic blood pressure were 53 ± 21 y, and 81 ± 32 mmHg, respectively. Overall, 24-h and in-hospital mortality were 1.2% and 2.5%, respectively. On multivariable analysis, all three SIs were independently associated with higher rates of 24-h and in-hospital mortality, blood product requirements, intensive care unit and hospital length of stay (P < 0.001). ED SI was superior to prehospital and delta SIs (P < 0.001) for all outcomes. On subanalysis of patients with moderate injuries, severe injuries, and positive delta SI, the results remained the same. CONCLUSIONS: ED SI outperformed both prehospital and delta SIs across all injury severities. Trauma triage guidelines should prioritize ED SI in the risk stratification of trauma patients who may benefit from earlier and more intense trauma activations.

Not all traumatic brain injury patients on preinjury anticoagulation are the same.

BACKGROUND: Prognostic significance of different anticoagulants in TBI patients remains unanswered. We aimed to compare effects of different anticoagulants on outcomes of TBI patients. METHODS: A secondary analysis of AAST BIG MIT. Blunt TBI patients ≥50 years using anticoagulants presenting ICH were identified. Outcomes were progression of ICH and need for neurosurgical intervention (NSI). RESULTS: 393 patients were identified. Mean age was 74 and most common anticoagulant was aspirin (30%), followed by Plavix (28%), and coumadin (20%). 20% had progression of ICH and 10% underwent NSI. On multivariate regression for ICH progression, warfarin, SDH, IPH, SAH, alcohol intoxication and neurologic exam deterioration were associated with increased odds. Warfarin, abnormal neurologic exam on presentation, and SDH were independent predictors of NSI. CONCLUSIONS: Our findings reflect a dynamic interaction between type of anticoagulants, bleeding pattern & outcomes. Future modifications of BIG may need to take the type of anticoagulant into consideration.

Does preinjury anticoagulation worsen outcomes among traumatic hemothorax patients? A nationwide retrospective analysis.

INTRODUCTION: Up to a quarter of all traumatic deaths are due to thoracic injuries. Current guidelines recommend consideration of evacuation of all hemothoraces with tube thoracostomy. The aim of our study was to determine the impact of pre-injury anticoagulation on outcomes of traumatic hemothorax patients. MATERIALS AND METHODS: We performed a 4-year (2017 - 2020) analysis of the ACS-TQIP database. We included all adult trauma patients (age ≥18 years) presenting with hemothorax and no other severe injuries (other body regions <3). Patients with a history of bleeding disorders, chronic liver disease, or cancer were excluded from this study. Patients were stratified into two groups based on the history of preinjury anticoagulant use (AC, preinjury anticoagulant use: No-AC, no preinjury anticoagulant use). Propensity score matching (1:1) was done by adjusting for demographics, ED vitals, injury parameters, comorbidities, thromboprophylaxis type, and trauma center verification level. Outcome measures were interventions for hemothorax (chest tube, video-assisted thoracoscopic surgery [VATS]), reinterventions (chest tube > once), overall complications, hospital length of stay (LOS), and mortality. RESULTS: A matched cohort of 6,962 patients (AC, 3,481; No-AC, 3,481) was analyzed. The median age was 75 years, and the median ISS was 10. The AC and No-AC groups were similar in terms of baseline characteristics. Compared to the No-AC group, AC group had higher rates of chest tube placement (46% vs 43%, p = 0.018), overall complications (8% vs 7%, p = 0.046), and longer hospital LOS (7[4-12] vs 6[3-10] days, p ≤ 0.001). Reintervention and mortality rates were similar between the groups (p>0.05). CONCLUSION: The use of preinjury anticoagulants in hemothorax patients negatively impacts patient outcomes. Increased surveillance is required while dealing with hemothorax patients on pre-injury anticoagulants, and consideration should be given to earlier interventions for such patients.

The Association Between the Timing of Initiation of Pharmacologic Venous Thromboembolism Prophylaxis with Outcomes in Burns Patients.

Hospitalized burn patients are at increased risk for venous thromboembolism (VTE). Guidelines regarding thromboprophylaxis in burn patients are unclear. This study aims to compare the outcomes of early versus late thromboprophylaxis initiation in burn patients. In this 3-year analysis of 2017-2019 ACS-TQIP, adult(18-64years) burn patients were identified after applying inclusion/exclusion criteria and stratified based on timing of initiation of VTE prophylaxis: Early(<24 hours of admission); Late(>24 hours). Outcomes were deep venous thrombosis(DVT), pulmonary embolism(PE), unplanned return to operating room (OR), unplanned intensive care unit (ICU) admission, post-prophylaxis packed red blood cells (PRBC) transfusion, and mortality. Nine thousand two hundred and seventy-two patients were identified. Overall, median age was 41years, 71.5% were male, and median[IQR] injury severity score was 3[1-8]. 53% had second-degree burns, and 80% had less than 40% of total body surface area affected. Median time to thromboprophylaxis initiation was 11[6-20.6]hours. Overall VTE rate was 0.9% (DVT-0.7%, PE-0.2%). On univariable analysis, early prophylaxis group had lower rates of DVT(0.6% vs 1.1%, P = .025), and PE(0.1% vs 0.6%, P < .001). On multivariable regression, late prophylaxis was associated with 1.8 times higher odds of DVT (aOR = 1.8, 95% CI = 1.04-3.11, P = .03), 4.8 times higher odds of PE(aOR = 4.8, 95% CI = 1.9-11.9, P < .001), and 2 times higher odds of unplanned ICU admission(aOR = 2.1, 95% CI = 1.4-3.1, P < .001). Furthermore, early thromboprophylaxis was not associated with increased odds of post-prophylaxis PRBC transfusion(aOR = 1.1, 95% CI = 0.8-1.4, P = .4), and mortality(aOR = 0.68, 95% CI = 0.4-1.1, P = .13). Early VTE prophylaxis in burn patients is associated with decreased rates of DVT and PE, without increasing the risk of bleeding and mortality. VTE prophylaxis may be initiated within 24 hours of admission to reduce VTE in this high-risk patient population.

Unequal Treatment? Confronting Racial, Ethnic, and Socioeconomic Disparity in Management of Survivors of Violent Suicide Attempt.

BACKGROUND: Psychiatric inpatient hospitalization is nearly always indicated for patients with recent suicidal behavior. We aimed to assess the factors associated with receiving mental health services during hospitalization or on discharge among survivors of suicide attempts in trauma centers. STUDY DESIGN: A 3-year analysis of the 2017 to 2019 American College of Surgeons TQIP. Adults (≥18 years) presenting after suicide attempts were included. Patients who died, those with emergency department discharge disposition, those with superficial lacerations, and those who were transferred to nonpsychiatric care facilities were excluded. Backward stepwise regression analyses were performed to identify predictors of receiving mental health services (inpatient psychiatric consultation/psychotherapy, discharge/transfer to a psychiatric hospital, or admission to a distinct psychiatric unit of a hospital). RESULTS: We identified 18,701 patients, and 56% received mental health services. The mean age was 40 ± 15 years, 72% were males, 73% were White, 57% had a preinjury psychiatric comorbidity, and 18% were uninsured. Of these 18,701 patients, 43% had moderate to severe injuries (Injury Severity Score > 8), and the most common injury was cut/stab (62%), followed by blunt mechanisms (falls, lying in front of a moving object, and intentional motor vehicle collisions) (18%) and firearm injuries (16%). On regression analyses, Black race, Hispanic ethnicity, male sex, younger age, and positive admission alcohol screen were associated with lower odds of receiving mental health services (p < 0.05). Increasing injury severity, being insured, having preinjury psychiatric diagnosis, and positive admission illicit drug screen were associated with higher odds of receiving mental health services (p < 0.05). CONCLUSIONS: Significant disparities exist in the management of survivors of suicide attempts. There is a desperate need for improved access to mental health services. Further studies should focus on delineating the cause of these disparities, identifying the barriers, and finding solutions.

Minimally Invasive Surgery for Genitourinary Trauma: A Nationwide Outcomes-Based Analysis.

INTRODUCTION: Bladder and ureteral injuries are uncommon in trauma patients but are associated with increased morbidity and mortality. Patients presenting with such injuries may undergo either open surgical repair or laparoscopic repair. We aimed to compare outcomes of open surgical approach and laparoscopy in trauma patients with isolated bladder and ureteral injury. We hypothesized that laparoscopy is associated with improved outcomes. METHODS: We performed a 2017 review of American College of Surgeons Trauma Quality Improvement Program and identified trauma patients with bladder and ureteral injury who underwent open surgical repair or laparoscopy. A 1:1 propensity score matching was performed adjusting for demographics, emergency department vitals (systolic blood pressure, heart rate, Glasgow Coma Scale), mechanism of injury, Injury Severity Score, each body region Abbreviated Injury Scale score, and transfusion units. Outcomes were rates of in-hospital major complications and mortality. RESULTS: Of the 1,004,440 trauma patients, 384 patients (open: 192 and laparoscopy: 192) were matched and included. The mean age was 36 ± 15 y, Injury Severity Score was 27 [27-48], 77% were males, and 56% of patients had a blunt mechanism of injury, and 44% had penetrating injuries. Overall mortality was 7.3%. On univariate analysis, mortality was lower in the open group as compared to the laparoscopy group (10.4% versus 4.2%, P = 0.019) and survivor-only hospital length of stay was longer in the open group (8 [8-9] versus 7 [5-11], P = 0.008). There was no difference in overall major complications (23% versus 21%, P = 0.621). On multivariate analysis, open surgical repair was independently associated with lower odds of mortality (adjusted odds ratio: 0.405, 95% confidence interval: [0.17-0.95], P-value = 0.038) CONCLUSIONS: In our analysis open surgical repair of bladder and ureteral injuries was associated with lower mortality with other outcomes being similar when compared to laparoscopy. Laparoscopic surgical repair may not have an advantage over the open surgical repair for bladder and ureteral injuries. Further prospective studies are needed to delineate the ideal surgical approach for these injuries.

Failure to Rescue in Emergency General Surgery: Impact of Fragmentation of Care.

OBJECTIVE: Compare EGS patient outcomes after index and nonindex hospital readmissions, and explore predictive factors for nonindex readmission. BACKGROUND: Readmission to a different hospital leads to fragmentation of care. The impact of nonindex readmission on patient outcomes after EGS is not well established. METHODS: The Nationwide Readmissions Database (2017) was queried for adult patients readmitted after an EGS procedure. Patients were stratified and propensity-matched according to readmission destination: index versus nonindex hospital. Outcomes were failure to rescue (FTR), mortality, number of subsequent readmissions, overall hospital length of stay, and total costs. Hierarchical logistic regression was performed to account for clustering effect within hospitals and adjusting for patient- and hospital-level potential confounding factors. RESULTS: A total of 471,570 EGS patients were identified, of which 79,127 (16.8%) were readmitted within 30 days: index hospital (61,472; 77.7%) versus nonindex hospital (17,655; 22.3%). After 1:1 propensity matching, patients with nonindex readmission had higher rates of FTR (5.6% vs 4.3%; P < 0.001), mortality (2.7% vs 2.1%; P < 0.001), and overall hospital costs [in $1000; 37 (27-64) vs 28 (21-48); P < 0.001]. Nonindex readmission was independently associated with higher odds of FTR [adjusted odds ratio 1.18 (1.03-1.36); P < 0.001]. Predictors of nonindex readmission included top quartile for zip code median household income [1.35 (1.08-1.69); P < 0.001], fringe county residence [1.08 (1.01-1.16); P = 0.049], discharge to a skilled nursing facility [1.28 (1.20-1.36); P < 0.001], and leaving against medical advice [2.32 (1.81-2.98); P < 0.001]. CONCLUSION: One in 5 readmissions after EGS occur at a different hospital. Nonindex readmission carries a heightened risk of FTR. LEVEL OF EVIDENCE: Level III Prognostic. STUDY TYPE: Prognostic.

Association Between Hemorrhage Control Interventions and Mortality in US Trauma Patients With Hemodynamically Unstable Pelvic Fractures.

Importance: Management of hemodynamically unstable pelvic fractures remains a challenge. Hemostatic interventions are used alone or in combination. There is a paucity of data on the association between the pattern of hemorrhage control interventions and outcomes after a severe pelvic fracture. Objective: To characterize clinical outcomes and study the patterns of hemorrhage control interventions in hemodynamically unstable pelvic fractures. Design, Setting, and Participants: In this cohort study, a retrospective review was performed of data from the 2017 American College of Surgeons Trauma Quality Improvement Program database, a national multi-institutional database of trauma patients in the United States. Adult patients (aged ≥18 years) with pelvic fractures who received early transfusions (≥4 units of packed red blood cells in 4 hours) and underwent intervention for pelvic hemorrhage control were identified. Use and order of preperitoneal pelvic packing (PP), pelvic angioembolization (AE), and resuscitative endovascular balloon occlusion of the aorta (REBOA) in zone 3 were examined and compared against the primary outcome of mortality. The associations between intervention patterns and mortality, complications, and 24-hour transfusions were further examined by backward stepwise regression analyses. Data analyses were performed in September 2021. Main Outcomes and Measures: Primary outcomes were rates of 24-hour, emergency department, and in-hospital mortality. Secondary outcomes were major in-hospital complications. Results: A total of 1396 patients were identified. Mean (SD) age was 47 (19) years, 975 (70%) were male, and the mean (SD) lowest systolic blood pressure was 71 (25) mm Hg. The median (IQR) Injury Severity Score was 24 (14-34), with a 24-hour mortality of 217 patients (15.5%), ED mortality of 10 patients (0.7%), in-hospital mortality of 501 patients (36%), and complication rate of 574 patients (41%). Pelvic AE was the most used intervention (774 [55%]), followed by preperitoneal PP (659 [47%]) and REBOA zone 3 (126 [9%]). Among the cohort, 1236 patients (89%) had 1 intervention, 157 (11%) had 2 interventions, and 3 (0.2%) had 3 interventions. On regression analyses, only pelvic AE was associated with a mortality reduction (odds ratio [OR], 0.62; 95% CI, 0.47 to 0.82; P < .001). Preperitoneal PP was associated with increased odds of complications (OR, 1.39; 95% CI, 1.07 to 1.80; P = .01). Increasing number of interventions was associated with increased 24-hour transfusions (ß = +5.4; 95% CI, +3.5 to +7.5; P < .001) and mortality (OR, 1.57; 95% CI, 1.05 to 2.37; P = .03), but not with complications. Conclusions and Relevance: This study found that among patients with pelvic fracture who received early transfusions and at least 1 invasive pelvic hemorrhage control intervention, more than 1 in 3 died, despite the availability of advanced hemorrhage control interventions. Only pelvic AE was associated with a reduction in mortality.

Failure-to-rescue and mortality after emergent pediatric trauma laparotomy: How are the children doing?

INTRODUCTION: Emergent trauma laparotomy is associated with mortality rates of up to 40%. There is a paucity of data on the outcomes of emergent trauma laparotomies performed in the pediatric population. The aim of our study was to describe the outcomes, including mortality and FTR, among pediatric trauma patients undergoing emergent laparotomy and identify factors associated with failure-to-rescue (FTR). METHODS: We performed a one-year (2017) retrospective cohort analysis of the American College of Surgeons Trauma Quality Improvement Program dataset. All pediatric trauma patients (age <18 years) who underwent emergent laparotomy (laparotomy performed within 2 h of admission) were included. Outcome measures were major in-hospital complications, overall mortality, and failure-to-rescue (death after in-hospital major complication). Multivariate regression analysis was performed to identify factors independently associated with failure-to-rescue. RESULTS: Among 120,553 pediatric trauma patients, 462 underwent emergent laparotomy. Mean age was 14±4 years, 76% of patients were male, 49% were White, and 50% had a penetrating mechanism of injury. Median ISS was 25 [13-36], Abdomen AIS was 3 [2-4], Chest AIS was 2 [1-3], and Head AIS was 2 [0-5]. The median time in ED was 33 [18-69] minutes, and median time to surgery was 49 [33-77] minutes. The most common operative procedures performed were splenectomy (26%), hepatorrhaphy (17%), enterectomy (14%), gastrorrhaphy (14%), and diaphragmatic repair (14%). Only 22% of patients were treated at an ACS Pediatric Level I trauma center. The most common major in-hospital complications were cardiac (9%), followed by infectious (7%) and respiratory (5%). Overall mortality was 21%, and mortality among those presenting with hypotension was 31%. Among those who developed in-hospital major complications, the failure-to-rescue rate was 31%. On multivariate analysis, age younger than 8 years, concomitant severe head injury, and receiving packed red blood cell transfusion within the first 24 h were independently associated with failure-to-rescue. CONCLUSIONS: Our results show that emergent trauma laparotomies performed in the pediatric population are associated with high morbidity, mortality, and failure-to-rescue rates. Quality improvement programs may use our findings to improve patient outcomes, by increasing focus on avoiding hospital complications, and further refinement of resuscitation protocols. LEVEL OF EVIDENCE: Level IV STUDY TYPE: Epidemiologic.

Nonoperative management of blunt abdominal solid organ injury: Are we paying enough attention to patients on preinjury anticoagulation?

BACKGROUND: This study aims to assess the impact of pre-injury anticoagulant use on outcomes of isolated blunt abdominal SOI patients who underwent NOM. METHODS: A 1-year(2017) analysis of the ACS-TQIP. We included all ≥18yrs trauma patients with isolated blunt abdominal-SOI who underwent NOM. Patients were stratified into two groups based on their history of pre-injury anticoagulant use. Propensity score matching was performed. RESULTS: A matched cohort of 2709 patients (AC, 903; No-AC,1806) was analyzed. Compared to the No-AC group, the AC group had higher rates of failure of NOM(2.6% vs. 4.5%, p = 0.03), cardiac arrest (1.2%vs. 3.1%, p = 0.02), acute kidney injury (2.4% vs. 4.2%, p < 0.01), myocardial infarction (0.6% vs. 1.4%,p = 0.03), and mortality (5.1%vs. 7.6%,p = 0.01), and longer hospital LOS (17[10-24]vs.17[12-26]days,p = 0.04) and ICU LOS (11[6-17]vs.11[7-18]days,p = 0.01). CONCLUSION: Among nonoperatively managed blunt abdominal SOI patients, preinjury use of anticoagulants negatively impacts outcomes. Extra surveillance is required while managing patients with blunt abdominal SOI on pre-injury anticoagulants. LEVEL OF EVIDENCE: Level III. STUDY TYPE: Therapeutic/care management.

After 9,000 laparotomies for blunt trauma, resuscitation is becoming more balanced and time to intervention shorter: Evidence in action.

BACKGROUND: Several advancements in hemorrhage control have been advocated for in the past decade, including balanced transfusions and earlier times to intervention. The aim of this study was to examine the effect of these advancements on outcomes of blunt trauma patients undergoing emergency laparotomy. METHODS: This is a 5-year (2013-2017) analysis of the Trauma Quality Improvement Program. Adult (18 years or older) blunt trauma patients with early (≤4 hours) packed red blood cell (PRBC) and fresh frozen plasma (FFP) transfusions and an emergency (≤4 hours) laparotomy for hemorrhage control were identified. Time-trend analysis of 24-hour mortality, PRBC/FFP ratio, and time to laparotomy was performed over the study period. The association between mortality and PRBC/FFP ratio, patient demographics, injury characteristics, transfusion volumes, and American College of Surgeons verification level was examined by hierarchical regression analysis adjusting for interyear variability. RESULTS: A total of 9,773 blunt trauma patients with emergency laparotomy were identified. The mean ± SD age was 44 ± 18 years, 67.5% were male, and median Injury Severity Score was 34 (range, 24-43). The mean ± SD systolic blood pressure at presentation was 73 ± 28 mm Hg, and the median transfusion requirements were PRBC 9 (range, 5-17) and FFP 6 (range, 3-12). During the 5-year analysis, time to laparotomy decreased from 1.87 hours to 1.37 hours ( p < 0.001), PRBC/FFP ratio at 4 hours decreased from 1.93 to 1.71 ( p < 0.001), and 24-hour mortality decreased from 23.0% to 19.3% ( p = 0.014). On multivariate analysis, decreased PRBC/FFP ratio was independently associated with decreased 24-hour mortality (odds ratio, 0.88; p < 0.001) and in-hospital mortality (odds ratio, 0.89; p < 0.001). CONCLUSION: Resuscitation is becoming more balanced and time to emergency laparotomy shorter in blunt trauma patients, with a significant improvement in mortality. Future efforts should be directed toward incorporating transfusion practices and timely surgical interventions as markers of trauma center quality. LEVEL OF EVIDENCE: Therapeutic/care management, level III.

Prospective validation of the Rib Injury Guidelines for traumatic rib fractures.

INTRODUCTION: The Rib Injury Guidelines (RIG) were developed to guide triage of traumatic rib fracture patients to home, regular floor, or intensive care unit (ICU) and standardize care. The RIG score is based on patient history, physical examination, and imaging findings. The aim of this study was to evaluate triage effectiveness and health care resources utilization following RIG implementation. METHODS: This is a prospective analysis at a level I trauma center from October 2017 to January 2020. Adult (18 years or older) blunt trauma patients with a diagnosis of at least one rib fracture on computed tomography imaging were included. Patients before (PRE) and after (POST) implementation of RIG were compared. In the POST group, patients were divided into RIG 1, RIG 2, and RIG 3 based on their RIG score. Outcomes were readmission for RIG 1 patients, unplanned ICU admission for RIG 2 patients, and overall ICU admission. Secondary outcomes were hospital length of stay (LOS) and mortality. RESULTS: A total of 1,100 patients were identified (PRE, 754; POST, 346). Mean ± SD age was 56 ± 19 years, 788 (71.6%) were male, and median Injury Severity Score was 14 (range, 10-22). The most common mechanism of injury was motor vehicle collision (554 [50.3%]), 253 patients (22.9%) had ≥5 rib fractures, and 53 patients (4.8%) had a flail chest. In the POST group, 74 patients (21.1%) were RIG 1; 121 (35.2%), RIG 2; and 151 (43.7%), RIG 3. No patient in RIG 1 was readmitted following initial discharge, and two patients (1.6%) in RIG 2 had an unplanned ICU admission (both for alcohol withdrawal syndrome). Patients after implementation of RIG had shorter hospital LOS (3 [1-6] vs. 4 [1-7] days; p = 0.019) and no difference in mortality (5.8% vs. 7.7%; p = 0.252). On multivariate analysis, RIG implementation was associated with decreased ICU admission (adjusted odds ratio, 0.55 [0.36-0.82]; p = 0.004). CONCLUSION: Rib Injury Guidelines are safe and effectively define triage of rib fracture patients with an overall reduction in ICU admissions, shorter hospital LOS, and no readmissions.

Open Versus Laparoscopic Repair of Traumatic Diaphragmatic Injury: A Nationwide Propensity-Matched Analysis.

INTRODUCTION: Minimally invasive surgical techniques have become routinely applied in the evaluation and treatment of patients with isolated traumatic diaphragmatic injuries (TDI). However, there remains a paucity of data that compares the laparoscopic repair to the open repair approach. The aim of our study is to examine patient outcomes between TDI patients managed laparoscopically versus those managed using open repair. METHODS: Adult (age ≥18 years) trauma patients presenting with TDI that required surgical repair were identified in the Trauma Quality Improvement Program database 2017. Patients were excluded if they underwent any other surgical procedure of the abdomen or chest. Patients were then stratified into 2 groups based on the surgical approach: laparoscopic repair of the diaphragm versus open repair. Propensity-score matching in a 1:2 ratio was performed. Primary outcome measures were in-hospital major complications and length of stay (LOS). Secondary outcome measure was in-hospital mortality. RESULTS: A total of 177 adult trauma patients who had a laparoscopic repair of their isolated diaphragmatic injury were matched to 354 patients who had an open repair. Mean age was 35 ± 16 years, 78% were male, and mean BMI was 27 ± 7 kg/m2. 67 percent of the patients had penetrating injuries, and the median ISS was 17 [9-21]. CT imaging was done in 67% of the patients, with 71% presenting with left-sided injury and 21% having visceral herniation. Conversion from laparoscopic to open was reported in 7.3% of the cases. Patients with a laparoscopic repair had significantly lower rates of major complications (5.6 versus 14.4%; P<0.001), shorter hospital LOS (6 [3-9] versus 9 [5-13] days; P<0.001) and ICU LOS (3 [2-7] versus 5 [2-10] days; P<0.001). No difference was found in rates of in-hospital mortality (0.6 versuss 2.0%; P = 0.129) between the 2 groups. CONCLUSION: Laparoscopic repair of traumatic diaphragmatic injury was associated with decreased morbidity and a shorter hospital course, with a low conversion rate to open repair. Future studies remain necessary to further explore the long-term outcomes of patients with such injury. LEVEL OF EVIDENCE: Level III STUDY TYPE: Therapeutic.

Firearm-Related Injuries: A Single Center Experience.

INTRODUCTION: Firearm-related injuries (FRI) are an important public health crisis in the US. There is relatively less city level data examining the injury-related trends in Tucson, Arizona. Our study aims to examine FRI, in Southern Arizona's only Level I trauma center. METHODS: We conducted a (2014-2019) review of our Level-I trauma center registry. We selected all patients who were evaluated for a FRI. We collected patient and center related variables. Our outcomes were the trends of FRI, injury-related characteristics, and mortality. Cochran-Armitage trend analysis was performed. RESULTS: A total of 1012 FRI patients were identified. The majority of patients were teenagers (32%) and young adults (30%), and 88% were male. Greater than 80% of patients belonged to the low/low-middle socioeconomic class, and 18.5% completed college. The most common firearm utilized was the handgun (45%). The prevalence of FRI increased significantly (2014:15%; 2019:21%; P< 0.01). The most common injury intention was assault (75%). The median ISS was 17(9-25) with most injuries sustained to the extremities (23%). Also, 25% required emergent operative intervention. There is a significant rise in the number of severely injured patients (ISS≥25) (2014:12.1%, 2019:20%; P< 0.01), self-inflicted injuries (2014:10%, 2019:17%; P < 0.01), unintentional injuries (2014:6%, 2019:12%; P< 0.01), and mortality (2014:11%; 2019:19%; P< 0.01). A high prevalence of substance abuse was noted (73% alcohol, 64% drugs). CONCLUSIONS: The prevalence of FRI at our center has been rising over the past decade with a shift towards more severe injuries and higher mortality rates. Addressing these alarming changes requires targeted interventions on multiple frontiers.

Traumatic Femoral Artery Injuries and Predictors of Compartment Syndrome: A Nationwide Analysis.

BACKGROUND: The femoral artery is commonly injured following lower extremity trauma. If not identified early and addressed properly, it can lead to compartment syndrome (CS) and limb amputation. The aim of this study is to examine traumatic femoral artery injuries and identify risk factors for the development of lower extremity CS. METHODS: Adult (≥18 years) patients who presented with traumatic femoral artery injuries were identified in the Trauma Quality Improvement Program 2017. Patients were stratified into two groups, those with evidence of lower extremity compartment syndrome (CS) and those without CS (NCS), for comparison. Multivariate regression analysis was performed. RESULTS: A total of 1,297 adult trauma patients with femoral artery injury were identified. Mean age was 36 ± 15 y, 86% were male, and 68% had penetrating injuries. Median extremity abbreviated injury scale (AIS) was 3 [3,4], and median injury severity score (ISS) was 27 [22-41]. 68 (5.2%) patients were diagnosed with CS of the lower extremity, 66 (97.1%) of those patients underwent fasciotomy and one (1.5%) patient eventually had an amputation. On multivariate regression analysis, concomitant femoral vein, femoral nerve, and popliteal artery injuries and early need for blood transfusions were independent risk factors for the development of CS (OR 3.1, 3.8, 4.3, and 2.5 respectively). CONCLUSIONS: CS following traumatic femoral artery injury is a relatively common finding. Physicians must maintain a high index of suspicion and should consider prophylactic fasciotomy in the setting of combined femoral vein and nerve injuries, combined popliteal artery injury, and multiple blood transfusions.

Open vs Endovascular Treatment of Traumatic Peripheral Arterial Injury: Propensity Matched Analysis.

BACKGROUND: Arterial injuries occur in the setting of blunt and penetrating trauma. Despite increasing use, there remains a paucity of data comparing long-term outcomes of endovascular vs open repair management of these injuries. The aim of our study was to compare outcomes and readmission rates of open vs endovascular repair of traumatic arterial injuries. STUDY DESIGN: The National Readmission Database (2011-2014) was queried for all adult (age ≥ 18 y) patients presenting with peripheral arterial (axillary, brachial, femoral, and popliteal) injuries. Patients were stratified into 2 groups based on intervention: open vs endovascular approach. Propensity score matching (1:2 ratio) was performed. Outcomes measures were complications, length of stay (LOS), 30-day readmission, and cost of readmission. RESULTS: A matched cohort of 786 patients was obtained (endovascular: 262, open: 524). Mean age was 45 ± 17 years, and 79% were males. Median LOS was 4 (range 2-6) days for the endovascular group vs 3 (range 2-5) days for the open group (p < 0.01). The endovascular group had higher rates of seroma (4% vs 2%; p = 0.04) and arterial thrombosis (13% vs 7%; p < 0.01) during index hospitalization. Patients who underwent endovascular repair had higher 30-day readmission (11% vs 7%; p = 0.03) and a higher 30-day open-reoperation rate (6% vs 2%; p < 0.01). On subanalysis of the patients who were readmitted, the median cost of each readmission was higher in the endovascular group $47,000 ($27,202-$56,763) compared with $21,000 ($11,889-$43,503) in the open group. CONCLUSIONS: Endovascular repair for peripheral arterial injuries was associated with higher rates of in-hospital complications, readmissions, and costs. As this new technology continues to undergo refinement, a thorough re-evaluation of its indications, risks, and benefits is warranted.

Frail geriatric patients with acute calculous cholecystitis: Operative versus nonoperative management?

INTRODUCTION: Nonoperative management of acute calculous cholecystitis (ACC) in the frail geriatric population is underexplored. The aim of our study was to examine long-term outcomes of frail geriatric patients with ACC treated with cholecystectomy compared with initial nonoperative management. METHODS: We conducted a 2017 analysis of the Nationwide Readmissions Database and included frail geriatric (≥65 years) patients with ACC. Frailty was assessed using the five-factor modified frailty index. Patients were stratified into those undergoing cholecystectomy at index admission (operative management [OP]) versus those managed with nonoperative intervention (nonoperative management [NOP]). The NOP group was further subdivided into those who received antibiotics only and those who received percutaneous drainage. Primary outcomes were procedure-related complications in the OP group and 6-month failure of NOP (readmission with cholecystitis). Secondary outcomes were mortality and overall hospital length of stay. RESULTS: A total of 53,412 geriatric patients with ACC were identified, 51.0% of whom were frail: 16,791 (61.6%) in OP group and 10,472 (38.4%) in NOP group (3,256 had percutaneous drainage, 7,216 received antibiotics only). Patients were comparable in age (76 ± 7 vs. 77 ± 8 years; p = 0.082) and modified frailty index (0.47 vs. 0.48; p = 0.132). Procedure-related complications in the OP group were 9.3%, and 6-month failure of NOP was 18.9%. Median time to failure of NOP management was 36 days (range, 12-78 days). Mortality was higher in the frail NOP group (5.2 vs. 3.2%; p < 0.001). The NOP group had more days of hospitalization (8 [4-15] vs. 5 [3-10]; p < 0.001). Both receiving antibiotics only (odds ratio, 1.6 [1.3-2.0]; p < 0.001) and receiving percutaneous drainage (odds ratio, 1.9 [1.7-2.2]; p < 0.001) were independently associated with increased mortality. CONCLUSION: One in five patients failed NOP and subsequently had complicated hospital stays. Nonoperative management of frail elderly ACC patients may be associated with significant morbidity and mortality. LEVEL OF EVIDENCE: Therapeutic, level IV.
