Biochemical markers in emergency thoracic surgery in penetrating trauma.

BACKGROUND: Violent interpersonal acts account for a large proportion of unnatural deaths in South Africa. A significant proportion of unnatural deaths are due to penetrating thoracic trauma and preventable haemorrhage. Current indications for emergent thoracotomy are unreliable. We propose the use of lactate, shock index (SI) and base deficit (BD) as a triage tool in patients with penetrating thoracic injuries to identify those requiring surgical intervention. METHODS: A review of the trauma registry of the Charlotte Maxeke Johannesburg Academic Hospital (CMJAH) was carried out between March 2011 and March 2016. Four hundred and ninety (490) patients were collected consisting of a non-operative group of 246 patients and an operative group of 244 patients. We compared lactate, SI and BD independently and within panels to ascertain which would best predict the need for operative intervention in these patients. Abnormal was defined as lactate ≥ 4 mmol/l, SI ≥ 0.8 and BD ≤ -4 mmol/l. RESULTS: Of the 490 patients, lactate (p < 0.001), SI (p < 0.001) and BD (p < 0.001) differed significantly between operative and non-operative groups. Statistical significance was lost (p = 0.34) once BD was analysed in combination with lactate and SI. Lactate alone was a strong predictor of the need for intervention (area under the curve (AUC) = 0.814). The strongest predictor was a combined panel of lactate and SI (AUC = 0.8308, p < 0.001). CONCLUSION: Lactate and SI in combination are useful as triage tools, and could assist in decision making, by predicting which patients are more likely to require surgical intervention.

Evaluating patient factors, operative management and postoperative outcomes in trauma laparotomy patients worldwide: a protocol for a global observational multicentre trauma study.

INTRODUCTION: Trauma contributes to the greatest loss of disability-adjusted life-years for adolescents and young adults worldwide. In the context of global abdominal trauma, the trauma laparotomy is the most commonly performed operation. Variation likely exists in how these patients are managed and their subsequent outcomes, yet very little global data on the topic currently exists. The objective of the GOAL-Trauma study is to evaluate both patient and injury factors for those undergoing trauma laparotomy, their clinical management and postoperative outcomes. METHODS: We describe a planned prospective multicentre observational cohort study of patients undergoing trauma laparotomy. We will include patients of all ages who present to hospital with a blunt or penetrating injury and undergo a trauma laparotomy within 5 days of presentation to the treating centre. The study will collect system, patient, process and outcome data, following patients up until 30 days postoperatively (or until discharge or death, whichever is first). Our sample size calculation suggests we will need to recruit 552 patients from approximately 150 recruiting centres. DISCUSSION: The GOAL-Trauma study will provide a global snapshot of the current management and outcomes for patients undergoing a trauma laparotomy. It will also provide insight into the variation seen in the time delays for receiving care, the disease and patient factors present, and patient outcomes. For current standards of trauma care to be improved worldwide, a greater understanding of the current state of trauma laparotomy care is paramount if appropriate interventions and targets are to be identified and implemented.

'No zone' approach in the management of penetrating neck injuries - an Australian Tertiary Trauma Centre experience.

PURPOSE: Penetrating neck injuries (PNIs), defined as deep to the platysma, can result in significant morbidity and mortality. Management has evolved from a zone-based approach to a 'no zone' algorithm, resulting in reduced non-therapeutic neck exploration rates. The aim of this study was to examine PNIs and its management trends in an Australian tertiary trauma centre, to determine if a 'no zone' approach could be safely implemented in this population, as has been demonstrated internationally. METHODOLOGY: This was a retrospective observational study at a level 1 adult Australian tertiary trauma centre using prospectively collated data from January 2008 to December 2018. Observed data included age, gender, mechanism of injury, computed tomography angiography (CT-A) use and operative intervention. Patients were examined based on zone of injury and presenting signs - 'hard', 'soft' or 'asymptomatic'. Major outcomes were CT-A usage, positive CT-A correlation with therapeutic neck explorations and negative neck exploration rates. RESULTS: This study identified 238 PNI patients, with 204 selected for review. Most injuries occurred in zone 2 (71.6%), with soft signs accounting for 53.4% of cases. Over 10 years, CT-A utilization increased from 55% to 94.1%, with positive CT-As being more likely to yield therapeutic neck explorations. There was a general decreased trend in operative intervention but without a clear reduction in non-therapeutic neck explorations. CONCLUSION: Our data suggests similarities with results from around the world, demonstrating that the 'no zone' approach should be considered when managing PNIs, but with clinician discretion in individual cases.

Outcomes by time-to-OR for penetrating abdominal trauma patients.

INTRODUCTION: Time-To-OR is a critical process measure for trauma performance. However, this measure has not consistently demonstrated improvement in outcome. STUDY DESIGN: Using TQIP, we identified facilities by 75th percentile time-to-OR to categorize slow, average, and fast hospitals. Using a GEE model, we calculated odds of mortality for all penetrating abdominal trauma patients, firearm injuries only, and patients with major complication by facility speed. We additionally estimated odds of mortality at the patient level. RESULTS: Odds of mortality for patients at slow facilities was 1.095; 95% CI: 0.746, 1.608; p = 0.64 compared to average. Fast facility OR = 0.941; 95% CI: 0.780, 1.133; p = 0.52. At the patient-level each additional minute of time-to-OR was associated with 1.5% decreased odds of in-hospital mortality (OR 0.985; 95% CI:0.981, 0.989; p < 0.001). For firearm-only patients, facility speed was not associated with odds of in-hospital mortality (p-value = 0.61). Person-level time-to-OR was associated with 1.8% decreased odds of in-hospital mortality (OR 0.982; 95% CI: 0.977, 0.987; p < 0.001) with each additional minute of time-to-OR. Similarly, failure-to-rescue analysis showed no difference in in-hospital mortality at the patient level (p = 0.62) and 0.4% decreased odds of in-hospital mortality with each additional minute of time-to-OR at the patient level (OR 0.996; 95% CI: 0.993, 0.999; p = 0.004). CONCLUSION: Despite the use of time-to-OR as a metric of trauma performance, there is little evidence for improvement in mortality or complication rate with improved time-to-OR at the facility or patient level. Performance metrics for trauma should be developed that more appropriately approximate patient outcome.

Characteristics of traumatic major haemorrhage in a tertiary trauma center.

BACKGROUND: Major traumatic haemorrhage is potentially preventable with rapid haemorrhage control and improved resuscitation techniques. Although advances in prehospital trauma management, haemorrhage is still associated with high mortality. The aim of this study was to use a recent pragmatic transfusion-based definition of major bleeding to characterize patients at risk of major bleeding and associated outcomes in this cohort after trauma. METHODS: This was a retrospective cohort study including all trauma patients (n = 7020) admitted to a tertiary trauma center from January 2015 to June 2020. The major bleeding cohort (n = 145) was defined as transfusion of 4 units of any blood components (red blood cells, plasma, or platelets) within 2 h of injury. Univariate and multivariable logistic regression analyses were performed to identify risk factors for 24-hour and 30-day mortality post trauma admission. RESULTS: In the major bleeding cohort (n = 145; 145/7020, 2.1% of the trauma population), there were 77% men (n = 112) and 23% women (n = 33), median age 39 years [IQR 26-53] and median Injury Severity Score (ISS) was 22 [IQR 13-34]. Blunt trauma dominated over penetrating trauma (58% vs. 42%) where high-energy fall was the most common blunt mechanism and knife injury was the most common penetrating mechanism. The major bleeding cohort was younger (OR 0.99; 95% CI 0.98 to 0.998, P = 0.012), less female gender (OR 0.66; 95% CI 0.45 to 0.98, P = 0.04), and had more penetrating trauma (OR 4.54; 95% CI 3.24 to 6.36, P = 0.001) than the rest of the trauma cohort. A prehospital (OR 2.39; 95% CI 1.34 to 4.28; P = 0.003) and emergency department (ED) (OR 6.91; 95% CI 4.49 to 10.66, P = 0.001) systolic blood pressure < 90 mmHg was associated with the major bleeding cohort as well as ED blood gas base excess < -3 (OR 7.72; 95% CI 5.37 to 11.11; P < 0.001) and INR > 1.2 (OR 3.09; 95% CI 2.16 to 4.43; P = 0.001). Emergency damage control laparotomy was performed more frequently in the major bleeding cohort (21.4% [n = 31] vs. 1.5% [n = 106]; OR 3.90; 95% CI 2.50 to 6.08; P < 0.001). There was no difference in transportation time from alarm to hospital arrival between the major bleeding cohort and the rest of the trauma cohort (47 [IQR 38;59] vs. 49 [IQR 40;62] minutes; P = 0.17). However, the major bleeding cohort had a shorter time from ED to first emergency procedure (71.5 [IQR 10.0;129.0] vs. 109.00 [IQR 54.0; 259.0] minutes, P < 0.001). In the major bleeding cohort, patients with penetrating trauma, compared to blunt trauma, had a shorter alarm to hospital arrival time (44.0 [IQR 35.5;54.0] vs. 50.0 [IQR 41.5;61.0], P = 0.013). The 24-hour mortality in the major bleeding cohort was 6.9% (10/145). All fatalities were due to blunt trauma; 40% (4/10) high energy fall, 20% (2/10) motor vehicle accident, 10% (1/10) motorcycle accident, 10% (1/10) traffic pedestrian, 10% (1/10) traffic other, and 10% (1/10) struck/hit by blunt object. In the logistic regression model, prehospital cardiac arrest (OR 83.4; 95% CI 3.37 to 2063; P = 0.007) and transportation time (OR 0.95, 95% CI 0.91 to 0.99, P = 0.02) were associated with 24-hour mortality. RESULTS: Early identification of patients at high risk of major bleeding is challenging but essential for rapid definitive haemorrhage control. The major bleeding trauma cohort is a small part of the entire trauma population, and is characterized of being younger, male gender, higher ISS, and exposed to more penetrating trauma. Early identification of patients at high risk of major bleeding is challenging but essential for rapid definitive haemorrhage control.

Management of contained penetrating cardiac injury in a patient with prior cardiac surgery.

Penetrating cardiac injuries usually require emergent surgical intervention. Our patient presented to the trauma centre with multiple stab wounds to the neck, chest, epigastric region and abdomen. She arrived haemodynamically stable, and her initial Focused Assessment with Sonography for Trauma exam was negative. Her chest X-ray did not show any evident pneumothorax or haemothorax. Due to her injury pattern, she was taken to the operating room for exploratory laparotomy and neck exploration. Postoperatively, she was taken for CT and found to have a contained cardiac rupture. The injury was contained within previous scar tissue from her prior cardiac surgery. Further evaluation revealed that the injury included a penetrating stab wound to the right ventricle and a traumatic ventricular septal defect (VSD). She subsequently underwent a redo sternotomy with the repair of the penetrating stab wound and the VSD. Cardiology, intensive care, trauma surgery and cardiothoracic surgery coordinated her care from diagnosis, management and recovery. This case highlights the challenges in the management of cardiac injuries and the benefits of a multidisciplinary approach to care for complex cardiac injuries.

The Role of Minimally Invasive Surgeries in Trauma.

This article delves into the role of minimally invasive surgeries in trauma, specifically laparoscopy and video-assisted thoracic surgery (VATS). It discusses the benefits of laparoscopy over traditional laparotomy, including its accuracy in detecting peritoneal violation and intraperitoneal injuries caused by penetrating trauma. The article also explores the use of laparoscopy as an adjunct to nonoperative management of abdominal injuries and in cases of blunt trauma with unclear abdominal injuries. Furthermore, it highlights the benefits of VATS in diagnosing and treating thoracic injuries, such as traumatic diaphragmatic injuries, retained hematomas, and persistent pneumothorax.

A pregnant woman with long-standing, retained intraabdominal glass shards who gave birth to a live infant with no complications: a case report.

BACKGROUND: Most cases of traumatic injury during pregnancy involve blunt trauma, with penetrating trauma being uncommonly rare. In glass shard injuries, fragments often penetrate deeply, and multiple injuries may occur simultaneously; attention must be paid to the possibility of organ injury from the residual fragments. However, no case of this occurring during pregnancy has been reported yet. CASE PRESENTATION: We present the case of a 34-year-old pregnant Cameroonian woman who retained intraabdominal glass shards following a penetrating injury at 13 weeks gestation and not diagnosed until 22 weeks gestation. Notably, this patient continued the pregnancy without complications and gave birth via cesarean section at 36 weeks gestation. CONCLUSION: In pregnant women sustaining a penetrating glass trauma during pregnancy, careful attention should be paid to the fragments; in that case, computed tomography is a useful modality for accurately visualizing any remaining fragments in the body. Essentially, the foreign bodies in glass shard injuries during pregnancy should be removed immediately, but conservative management for term delivery is an important choice for patients at risk for preterm delivery.

Periarticular blast wounds without fracture a prospective case series.

BACKGROUND: During the wars in Afghanistan and Iraq most injuries to service members involved the musculoskeletal system. These wounds often occurred around joints, and in some cases result in traumatic arthrotomy-a diagnosis that is not always clear, especially when there is no concomitant articular fracture. The aim of the present study is to evaluate the diagnosis and treatment of peri-articular blast injuries without fracture. METHODS: The study cohort included 12 consecutive patients (12 involved extremities) who sustained peri-articular blast wounds of the extremities without fractures. The diagnosis of penetrating articular injury was based on clinical examination, radiographic findings, or aspiration. A peri-articular wound was defined as any wound, or radio-opaque blast fragment, within 5 cm of a joint. The New Injury Severity Score (NISS) was calculated for each patient. Four patients had upper, and 8 patients had lower extremity injuries. Nine of 12 patients had joint capsular penetration and underwent joint irrigation and debridement. RESULTS: Two patients had retained intra-articular metal fragments. One patient had soft tissue blast wounds within 5 cm of a joint but did not have joint capsule penetration. There were no significant differences (p = 0.23) between the distribution of wounds to upper versus lower extremities. However, there were a significantly greater number of blast injuries attributed to Improvised Explosive Devices (IEDs) than from other blast mechanisms (p = 0.01). CONCLUSION: Extremity blast injuries in the vicinity of joints involving only soft tissues present a unique challenge in surgical management. A high index of suspicion should be maintained for joint capsular penetration so that intra-articular injuries may be appropriately treated.

Management of penetrating cardiac injury and tricuspid regurgitation with extracorporeal-membrane oxygenation (ECMO): a case report.

BACKGROUND: Gunshot wounds (GSW) to the heart are lethal, and most patients die before they arrive to the hospital. Survival decreases with number of cardiac chambers involved. We report a case of a 17-year-old male who survived a GSW injury involving two cardiac chambers with acute severe tricuspid regurgitation (TR) who subsequently developed cardiogenic shock requiring extracorporeal membrane oxygenation (ECMO) support. CASE PRESENTATION: A 17-year-old male sustained a single gunshot wound to the left chest, resulting in pericardial tamponade and right hemothorax. Emergency sternotomy revealed injury to the right ventricle and inferior cavoatrial junction with the adjacent pericardium contributing to a right hemothorax. The cardiac injuries were repaired primarily. Tricuspid regurgitation was confirmed immediately postoperatively. Five days after presentation, the patient developed cardiogenic shock secondary to TR requiring emergent stabilization with ECMO. He subsequently underwent successful tricuspid valve replacement. CONCLUSIONS: This is the first report to our knowledge of successful ECMO support of severe TR due to gunshot injury to the heart.

Patients Lost to Follow-up After Injury: Who are They and What are Their Long-Term Outcomes?

INTRODUCTION: Trauma patients are at high risk for loss to follow-up (LTFU) after hospital discharge. We sought to identify risk factors for LTFU and investigate associations between LTFU and long-term health outcomes in the trauma population. METHODS: Trauma patients with an Injury Severity Score ≥9 admitted to one of three Level-I trauma centers, 2015-2020, were surveyed via telephone 6 mo after injury. Univariate and multivariate analyses were performed to assess factors associated with LTFU and several long-term outcomes. RESULTS: Of 3609 patients analyzed, 808 (22.4%) were LTFU. Patients LTFU were more likely to be male (71% versus 61%, P = 0.001), Black (22% versus 14%, P = 0.003), have high school or lower education (50% versus 42%, P = 0.003), be publicly insured (23% versus 13%, P < 0.001), have a penetrating injury (13% versus 8%, P = 0.006), have a shorter length of stay (3.64 d ± 4.09 versus 5.06 ± 5.99, P < 0.001), and be discharged home without assistance (79% versus 50%, P < 0.001). In multivariate analyses, patients who followed up were more likely to require assistance at home (6% versus 11%; odds ratio [OR] 2.23, 1.26-3.92, P = 0.005), have new functional limitations (11% versus 26%; OR 2.91, 1.97-4.31, P = < 0.001), have daily pain (30% versus 48%; OR 2.11, 1.54-2.88, P = < 0.001), and have more injury-related emergency department visits (7% versus 10%; OR 1.93, 1.15-3.22, P = 0.012). CONCLUSIONS: Vulnerable populations are more likely to be LTFU after injury. Clinicians should be aware of potential racial and socioeconomic disparities in follow-up care after traumatic injury. Future studies investigating improvement strategies in follow-up care should be considered.

Mechanism matters: mortality and endothelial cell damage marker differences between blunt and penetrating traumatic injuries across three prehospital clinical trials.

Injury mechanism is an important consideration when conducting clinical trials in trauma. Mechanisms of injury may be associated with differences in mortality risk and immune response to injury, impacting the potential success of the trial. We sought to characterize clinical and endothelial cell damage marker differences across blunt and penetrating injured patients enrolled in three large, prehospital randomized trials which focused on hemorrhagic shock. In this secondary analysis, patients with systolic blood pressure < 70 or systolic blood pressure < 90 and heart rate > 108 were included. In addition, patients with both blunt and penetrating injuries were excluded. The primary outcome was 30-day mortality. Mortality was characterized using Kaplan-Meier and Cox proportional-hazards models. Generalized linear models were used to compare biomarkers. Chi squared tests and Wilcoxon rank-sum were used to compare secondary outcomes. We characterized data of 696 enrolled patients that met all secondary analysis inclusion criteria. Blunt injured patients had significantly greater 24-h (18.6% vs. 10.7%, log rank p = 0.048) and 30-day mortality rates (29.7% vs. 14.0%, log rank p = 0.001) relative to penetrating injured patients with a different time course. After adjusting for confounders, blunt mechanism of injury was independently predictive of mortality at 30-days (HR 1.84, 95% CI 1.06-3.20, p = 0.029), but not 24-h (HR 1.65, 95% CI 0.86-3.18, p = 0.133). Elevated admission levels of endothelial cell damage markers, VEGF, syndecan-1, TM, S100A10, suPAR and HcDNA were associated with blunt mechanism of injury. Although there was no difference in multiple organ failure (MOF) rates across injury mechanism (48.4% vs. 42.98%, p = 0.275), blunt injured patients had higher Denver MOF score (p < 0.01). The significant increase in 30-day mortality and endothelial cell damage markers in blunt injury relative to penetrating injured patients highlights the importance of considering mechanism of injury within the inclusion and exclusion criteria of future clinical trials.

No cupid, just an arrow: a penetrating injury into the interventricular septum.

BACKGROUND: Penetrating cardiac injuries are rare but often fatal, with 16-55% mortality. We report a patient who suffered a non-fatal occupational cardiac injury. CASE PRESENTATION: A 47-year-old man was operating an ironworker machine. A thin 3-cm metal fragment catapulted from the machine piercing the chest wall and the right ventricular outflow tract (RVOT), burrowing into the interventricular septum (IVS). The patient remained hemodynamically stable and walked to the nearest hospital. ECG-gated computed tomography revealed the exact location of the fragment within the IVS, allowing for detailed preoperative planning. The fragment was removed through a sternotomy and an incision through the RVOT. The postoperative course was uneventful. CONCLUSIONS: This case underscores the value of detailed preoperative imaging and the wide spectrum of clinical scenarios of penetrating cardiac injuries.

Mortality of traumatic chest injury and its predictors across sub-saharan Africa: systematic review and meta-analysis, 2024.

INTRODUCTION: Globally, chest trauma remain as a prominent contributor to both morbidity and mortality. Notably, patients experiencing blunt chest trauma exhibit a higher mortality rate (11.65%) compared to those with penetrating chest trauma (5.63%). AIM: This systematic review and meta-analysis aimed to assess the mortality rate and its determinants in cases of traumatic chest injuries. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist guided the data synthesis process. Multiple advanced search methods, encompassing databases such as PubMed, Africa Index Medicus, Scopus, Embase, Science Direct, HINARI, and Google Scholar, were employed. The elimination of duplicate studies occurred using EndNote version X9. Quality assessment utilized the Newcastle-Ottawa Scale, and data extraction adhered to the Joanna Briggs Institute (JBI) format. Evaluation of publication bias was conducted via Egger's regression test and funnel plot, with additional sensitivity analysis. All studies included in this meta-analysis were observational, ultimately addressing the query, what is the pooled mortality rate of traumatic chest injury and its predictors in sub-Saharan Africa? RESULTS: Among the 845 identified original articles, 21 published original studies were included in the pooled mortality analysis for patients with chest trauma. The determined mortality rate was nine (95% CI: 6.35-11.65). Predictors contributing to mortality included age over 50 (AOR 3.5; 95% CI: 1.19-10.35), a time interval of 2-6 h between injury and admission (AOR 3.9; 95% CI: 2.04-7.51), injuries associated with the head and neck (AOR 6.28; 95% CI: 3.00-13.15), spinal injuries (AOR 7.86; 95% CI: 3.02-19.51), comorbidities (AOR 5.24; 95% CI: 2.93-9.40), any associated injuries (AOR 7.9; 95% CI: 3.12-18.45), cardiac injuries (AOR 5.02; 95% CI: 2.62-9.68), the need for ICU care (AOR 13.7; 95% CI: 9.59-19.66), and an Injury Severity Score (AOR 3.5; 95% CI: 10.6-11.60). CONCLUSION: The aggregated mortality rate for traumatic chest injuries tends to be higher in sub-Saharan Africa. Factors such as age over 50 years, delayed admission (2-6 h), injuries associated with the head, neck, or spine, comorbidities, associated injuries, cardiac injuries, ICU admission, and increased Injury Severity Score were identified as positive predictors. Targeted intervention areas encompass the health sector, infrastructure, municipality, transportation zones, and the broader community.

Clinical Reasoning: A 24-Year-Old Woman With Penetrating Neck Injury From a Needlefish.

Evaluating patients with a traumatic spinal cord injury can be complicated by other injuries. In this case, a 24-year-old woman injured by a needlefish presented with combined motor and sensory defects, cranial nerve deficits, and a blunt vascular injury. This case highlights the importance of neurologic and vascular localizations and an understanding of spinal cord injuries involving various ascending and descending tracts. Appreciation of these anatomical considerations through this case illustrates the diagnostic approach to neurologic evaluation. While we present a traumatic etiology for multiple neurologic syndromes, this case gives readers an opportunity to develop a comprehensive differential diagnosis and tailor investigations for other relevant etiologies. Readers walking through this stepwise process will ultimately arrive at several distinct but related diagnoses.

Prognostic Significance of Multifactorial Analysis in Complex Cervical Aero-Digestive Trauma Cases.

Background and Objectives: In the context of complex aerodigestive cervical traumas, the prognosis and outcome heavily depend on risk factors, particularly injuries to the larynx, trachea, major digestive tissues, cervical vertebrae, and vascular structures. With the increasing prevalence of trauma as a public health concern, there is a pressing need for epidemiological research and the implementation of preventative measures. The purpose of this research is to establish the profile of the predictable impact factors that determine the prognosis of patients with complex cervical trauma. Methods and Methods: The study group consisted of 106 patients with complex cervical trauma pathology developed by various mechanisms such as car accidents, home-related accidents, aggression, gunshot wounds, and self-inflicted attempts, resulting in hospitalization in the E.N.T. Clinic at "St. Spiridon" Iași Hospital, from 2012 to 2016; medical records were the source of the collected data. Results: Hemodynamic instability upon admission associated with age, muscle and laryngeal injuries, and anemia were identified as negative prognostic factors. Additionally, the utilization of imaging-based paraclinical investigations for diagnosing traumatic lesions emerged as a positive prognostic factor in managing this pathology. The management of penetrating cervical trauma remains a subject of debate, with some advocating for surgical exploration beyond the platysma layer in all cases, while others argue for a more selective conservative approach due to a high rate of negative explorations. Conclusions: The statistical evaluation of epidemiological, clinical, lesion, paraclinical, and therapeutic parameters is needed to establish predictable risk factors in the prognosis of complex aerodigestive cervical trauma.

Patterns of firearm related injury in the elderly: A single institution analysis.

BACKGROUND: Firearm-related violence (FRV) is a public health crisis in the United States that impacts individuals across the lifespan. This study sought to investigate patterns of injury and outcomes of firearm-related injury (FRI) in elderly victims and the impact of social determinants of health on this age demographic. METHODS: A retrospective review of the trauma registry at a large Level I center was performed from 2016-2021. Patients over age 18 were included and FRI was defined by ICD 9 and 10 codes. Comparisons were then made between elderly (age > 65 years) and non-elderly (age 18-64 years) victims. The primary outcome was mortality. Secondary outcomes included hospital and intensive care unit length of stay, in-hospital complications and the impact of distressed community index (DCI) and insurance status on discharge disposition. RESULTS: 23,975 patients were admitted for traumatic injury and 4,133 (6 %) were elderly. Of these, 134 had penetrating injuries and 72 (54 %) were FRI. The elderly patients had a median age of 69y and they were predominantly black (50 %) males (85%). Over 75 % had some form of government insurance compared to less than 20% in non-elderly (p<0.001). 33 % of elderly FRIs were self-inflicted compared to only 4 % in the non-elderly cohort and their overall mortality rate was 25 % versus 15 % in non-elderly with FRI (p = 0.038). The median DCI for the non-elderly victims was 72.3 [IQR 53.7-93.1] compared to 63.7 [IQR 33.2-83.6] in the elderly (p < 0.001), however, over 50 % of elderly victims were living in "at risk" or "distressed" communities. CONCLUSION: FRV is a public health crisis across the lifespan and elderly individuals represent a vulnerable subset of patients with unique needs and public health considerations. While many interventions target youth and young adults, it is imperative to not overlook the elderly in injury prevention efforts, particularly self-directed violence. Additionally, given most elderly victims were on government funded insurance and had a higher likelihood of requiring more costly discharge dispositions, new policies should take into consideration the potential financial burden of FRV in the elderly.

To the point: Utility of laparoscopy for operative management of stabbing abdominal trauma.

BACKGROUND: Algorithms for managing penetrating abdominal trauma are conflicting or vague regarding the role of laparoscopy. We hypothesized that laparoscopy is underutilized among hemodynamically stable patients with abdominal stab wounds. METHODS: Trauma Quality Improvement Program data (2016-2019) were used to identify stable (SBP ≥110 and GCS ≥13) patients ≥16yrs with stab wounds and an abdominal procedure within 24hr of admission. Patients with a non-abdominal AIS ≥3 or missing outcome information were excluded. Patients were analyzed based on index procedure approach: open, therapeutic laparoscopy (LAP), or LAP-conversion to open (LCO). Center, clinical characteristics and outcomes were compared according to surgical approach and abdominal AIS using non-parametric analysis. RESULTS: 5984 patients met inclusion criteria with 7 â€‹% and 8 â€‹% receiving therapeutic LAP and LCO, respectively. The conversion rate for patients initially treated with LAP was 54 â€‹%. Compared to conversion or open, therapeutic LAP patients had better outcomes including shorter ICU and hospital stays and less infection complications, but were younger and less injured. Assessing by abdominal AIS eliminated ISS differences, meanwhile LAP patients still had shorter hospital stays. At time of admission, 45 â€‹% of open patients met criteria for initial LAP opportunity as indicated by comparable clinical presentation as therapeutic laparoscopy patients. CONCLUSIONS: In hemodynamically stable patients, laparoscopy remains infrequently utilized despite its increasing inclusion in current guidelines. Additional opportunity exists for therapeutic laparoscopy in trauma, which appears to be a viable alternative to open surgery for select injuries from abdominal stab wounds. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.
