Straight Leg Raise Cannot Replace Computed Tomography in the Detection of Spinal Column Fractures.

INTRODUCTION: An active straight leg raise (SLR) is a weight bearing test which assesses pain upon movement and a patient's ability to load their pelvis, lumbar, and thoracic spine. Since many stable patients undergo computed tomography (CT) scanning solely for spinal tenderness, our hypothesis is that performing active straight leg raising could effectively rule out lumbar and thoracic vertebral fractures. METHODS: Blunt trauma patients ≥18 years of age with Glasgow Coma Scale 15 presenting in hemodynamically stable condition were screened. Patients remaining in the supine position were asked to perform SLR at 12, 18, and 24 inches above the bed. The patient's ability to raise the leg, baseline pain, and pain at each level were assessed. Patients also underwent standard CT scanning of the chest, abdomen and pelvis. The clinical examination results were then matched post hoc with the official radiology reports. RESULTS: 99 patients were screened, 65 males and 34 females. Spinal fractures were present in 15/99 patients (16%). Mechanisms of injury included motor vehicle collision 51%, pedestrian struck 25%, fall1 9%, and other 4%. The median pain score of patients with and without significant spinal fractures at 12, 18, 24 inches was 7.5, 7, 6 and 5, 5, 4, respectively. At 24 inches, active SLR had sensitivity of 0.47, a specificity of 0.59, a positive predictive value of 0.17, and an negative predictive value of 0.86. CONCLUSIONS: Although SLR has been discussed as a useful adjunct to secondary survey and physical exam following blunt trauma, its positive and more importantly negative predictive value are insufficient to rule out spinal column fractures. Liberal indications for CT based upon mechanism and especially pain and tenderness are necessary to identify all thoraco-lumbar spine fractures.

How the APHA Maternal and Child Health Section Advanced the Public Health Approach to Gun Violence Prevention.

PURPOSE: This manuscript provides a history of efforts by the American Public Health Association (APHA) Maternal and Child Health Section (MCH Section) Gun Violence Prevention Workgroup (GVP Workgroup) to promote gun violence prevention (GVP) as a key public health priority both within the MCH Section and APHA, and nationally. DESCRIPTION: The MCH Section established a gun violence prevention workgroup in response to the murders of twenty first-grade children and six adults at Sandy Hook Elementary School. This article presents an overview of the accomplishments and challenges of the MCH Section GVP Workgroup in a context of ever-increasing gun violence. As of 2020, firearms became the leading cause of death for U.S. children and teens. ASSESSMENT: Over the past decade, a small group of volunteers helped maintain GVP as one of the top priorities of both the MCH Section and APHA. Endorsement by the MCH Section and APHA leadership facilitated MCH Section GVP Workgroup efforts including organizing a national conference, developing scientific sessions for APHA annual meetings, establishing coalitions, and providing ongoing education and outreach to APHA members. CONCLUSION: The MCH Section GVP Workgroup helped to both elevate and maintain focus on GVP as a top priority of the MCH Section and APHA, indirectly impacting national efforts to promote a public health approach to GVP. The ongoing epidemic of firearm violence highlights the importance of continuing and strengthening this work. Individuals at other national, state or local organizations might look to the efforts and accomplishment of the MCH Section GVP Workgroup in pursuing critical issues within their own organizations.

And Miles to Go Before We Sleep: EAST Diversity and Inclusivity Progress and Remaining Challenges.

OBJECTIVE: The aim of this study was to examine the diversity, equity, and inclusion landscape in academic trauma surgery and the EAST organization. SUMMARY BACKGROUND DATA: In 2019, the Eastern Association for the Surgery of Trauma (EAST) surveyed its members on equity and inclusion in the #EAST4ALL survey and assessed leadership representation. We hypothesized that women and surgeons of color (SOC) are underrepresented as EAST members and leaders. METHODS: Survey responses were analyzed post-hoc for representation of females and SOC in academic appointments and leadership, EAST committees, and the EAST board, and compared to the overall respondent cohort. EAST membership and board demographics were compared to demographic data from the Association of American Medical Colleges. RESULTS: Of 306 respondents, 37.4% identified as female and 23.5% as SOC. There were no significant differences in female and SOC representation in academic appointments and EAST committees compared to their male and white counterparts. In academic leadership, females were underrepresented ( P < 0.0001), whereas SOC were not ( P = 0.08). Both females and SOC were underrepresented in EAST board membership ( P = 0.002 and P = 0.043, respectively). Of EAST's 33 presidents, 3 have been white women (9%), 2 have been Black, non-African American men (6%), and 28 (85%) have been white men. When compared to 2017 AAMC data, women are well-represented in EAST's 2020 membership ( P < 0.0001) and proportionally represented on EAST's 2019-2020 board ( P > 0.05). CONCLUSIONS: The #EAST4ALL survey suggests that women and SOC may be underrepresented as leaders in academic trauma surgery. However, lack of high-quality demographic data makes evaluating representation of structurally marginalized groups challenging. National trauma organizations should elicit data from their members to re-assess and promote the diversity landscape in trauma surgery.

Educational Quality of YouTube Videos for Patients Undergoing Elective Procedures.

INTRODUCTION: YouTube has become a main resource used by patients for self-education on medicine. It is important for surgeons to understand the quality and reliability of videos that patients are likely to view about elective procedures. METHODS: Videos were categorized by view count and content creators. The top 20 videos for each term, sorted by relevance, were evaluated using DISCERN criteria, a question set externally validated to assess the quality of information regarding health treatment choices. DISCERN score (DS) closer to 5 indicate higher quality information and 1 indicates the opposite. Total scores were given: 15-26 (very poor), 27-38 (poor), 39-50 (fair), 51-62 (very good), and 63-75 (excellent). Search terms included "Wound Care", "Skin Grafting", "Tracheostomy", and "percutaneous endoscopic gastrostomy tube placement". RESULTS: In total, 80 unique videos were evaluated with a total view of 8,848,796. The mean overall DS was 2.15 and a mean bias DS was 2.46. The median DISCERN total score for each key term was Tracheostomy: 35 (poor), Skin Grafting 26 (very poor), percutaneous endoscopic gastrostomy: 32 (poor), and Wound Care: 40 (fair). CONCLUSIONS: YouTube videos surrounding elective procedures should be viewed cautiously in patient education despite wide availability. The videos in this study show high levels of bias and low DS. Healthcare providers should be aware of poor-quality consumer health information often disseminated in online media such as YouTube.

Drug and Alcohol Use in Trauma Patients Before and During the COVID-19 Pandemic.

INTRODUCTION: Since the implementation of national stay-at-home orders during the COVID-19 pandemic, there has been rising concerns regarding prolonged social isolation that many individuals face. Given the link between increased stress and alcohol and drug use, our study investigated admission trends and patterns of alcohol and drug use in trauma patients. METHODS: This was a single center, retrospective cohort study comparing trauma patients admitted before the pandemic and during the first wave. We compared patient demographics, injury characteristics, and outcomes of substance screen negative, positive, and unscreened patients admitted. Patients screened positive if they had a positive urine drug screen (UDS) and/or a blood alcohol concentration (BAC) ≥10 mg/dL. RESULTS: There were 3906 trauma admissions in the year prior to and 3469 patients in the first year of the pandemic. No significant demographic differences were presented across time periods. Rates of UDS and BAC screening remained consistent. Equivalent rates of alcohol and drug positivity occurred (34% versus 33%, 17% versus 18%, P = 0.49). The total prevalence of alcohol use disorders (4% versus 5%, P < 0.001) and psychiatric disorders (6% versus 7%, P = 0.02) increased during the pandemic. CONCLUSIONS: The prevalence of diagnosed alcohol use and psychiatric disorders in trauma patients increased during the COVID-19 pandemic while rates of acute alcohol and drug screen positivity remained the same. These observations suggest a possible link between pandemic stressors and exacerbation of alcohol use and psychiatric conditions in trauma patients. During a changing pandemic landscape, it remains pertinent to increased screening for these conditions regardless of substance screen positivity upon admission.

The Impact of Firearm Legislation on Firearm Deaths, 1991-2017.

Firearm violence is a major public health concern in the USA with firearm suicide and homicide accounting for the majority of gun deaths. The present work seeks to explore the role of firearm legislation in reducing suicide and homicide rates. Using the State Firearm Law Database (www.statefirearmlaws.org), suicide and homicide rates were compared across the 50 US states from 1991 to 2017. A firearm regulations index was computed to represent the total number of state firearm laws. Generalized estimating equations were used to explore population-level increases or decreases in firearm regulations and their association with state suicide and homicide rates after controlling for several state-level covariates. Even after accounting for several key covariates (US region; time; gun ownership; percent of the state population that was White, Black, below the poverty line and 25 years or older with a bachelor's degree; incarceration rate, unemployment rate and divorce rate), we found that firearm laws significantly predicted state firearm suicide and homicide rates. States with greater numbers of laws had reduced suicide and homicide rates compared with those with fewer laws. The present findings point to the role of firearm legislation in curbing rates of gun violence across the USA.

Prevention of Firearm Violence Through Specific Types of Community-based Programming: An Eastern Association for the Surgery of Trauma Evidence-based Review.

OBJECTIVE: The purpose of this review was to provide an evidence-based recommendation for community-based programs to mitigate gun violence, from the Eastern Association for the Surgery of Trauma (EAST). SUMMARY BACKGROUND DATA: Firearm Injury leads to >40,000 annual deaths and >115,000 injuries annually in the United States. Communities have adopted culturally relevant strategies to mitigate gun related injury and death. Two such strategies are gun buyback programs and community-based violence prevention programs. METHODS: The Injury Control and Violence Prevention Committee of EAST developed Population, Intervention, Comparator, Outcomes (PICO) questions and performed a comprehensive literature and gray web literature search. Using GRADE methodology, they reviewed and graded the literature and provided consensus recommendations informed by the literature. RESULTS: A total of 19 studies were included for analysis of gun buyback programs. Twenty-six studies were reviewed for analysis for community-based violence prevention programs. Gray literature was added to the discussion of PICO questions from selected websites. A conditional recommendation is made for the implementation of community-based gun buyback programs and a conditional recommendation for community-based violence prevention programs, with special emphasis on cultural appropriateness and community input. CONCLUSIONS: Gun violence may be mitigated by community-based efforts, such as gun buybacks or violence prevention programs. These programs come with caveats, notably community cultural relevance and proper support and funding from local leadership.Level of Evidence: Review, Decision, level III.

Uncovering Disparities in Scholarly Productivity among Junior Surgical Society Grant Recipients.

BACKGROUND: Despite increasing the number of women and ethnic minority groups in surgery, the academic advancement of such individuals within surgical fields lags behind Caucasian men. We sought to identify gender and ethnic inequalities in the receipt of surgical society research grants for young faculty investigators and compare the scholarly productivity of these groups. MATERIALS AND METHODS: In this cross-sectional and retrospective study, the gender and race of surgical society grant recipients were determined from surgical society Web sites. Surgical society grants aimed at providing research grants for junior faculty investigators were analyzed. Using the Scopus database, each recipient's scholarly productivity was determined by means of h-index, a standardized measure of the quantity and impact of an individual's published articles. We generated descriptive statistics to compare the gender, race, and h-index of grant recipients in the years 2006-2008 and 2016-2018. RESULTS: Between 2006 and 2008, there were 68 research grant recipients. Of these recipients, 79% were men and 21% were women. The racial breakdown was 54% Caucasian men, 22% Asian men, 1.4% African American men, 1.4% Hispanic men, 12% Caucasian women, 7% Asian Women, and 1.4% African American women. The average h-index of the male and female recipients is 25 (±14) and 24 (±14), respectively (P = 0.81). Between 2016 and 2018, there were 113 research grant recipients. Of these recipients, 66% were men and 34% were women. The racial breakdown was 47% Caucasian men, 16% Asian men, 3.5% African American men, 1% Hispanic men, 26% Caucasian women, 3.5% Asian women, and 3.5% African American women. The average h-index of the male and female recipients is 12 (±8) and 9 (±6), respectively (P = 0.046). Caucasian women had the only statistically significant change in the proportion of grant recipients from 2006-2008 to 2016-2018, with an increase from 12% to 26% (P = 0.02). CONCLUSIONS: Most surgical society research grants for young investigators continue to be awarded to Caucasian men, with Caucasian women earning a distant second in the 2016-2018 cohort. Ethnic minorities continue to be awarded less research grants than Caucasian recipients. Overall, the average h-index of women was less than men. This study highlights the persistent need for surgical societies to consider gender and ethnic disparities when awarding junior investigator grants, including barriers minority groups may face in achieving the same h-index as Caucasian men.

Unpacking the Causes of Post-Traumatic Stress Disorder in Violently Injured Patients.

BACKGROUND: Violence is a public health problem that disproportionately affects urban communities. The root causes of PTSD and effects on quality of life, substance abuse, and mental health are unclear. The purpose of this study was to evaluate the prevalence of PTSD and its root causes to direct services to be provided in a hospital-based violence intervention program. METHODS: Victims of Violence (VOVs) at University Hospital were approached from December 2017 to June 2019. They completed several validated patient-reported outcome surveys, including the Traumatic Life Events Questionnaire, the Peritraumatic Dissociative Experiences Questionnaire, Peritraumatic Dissociative Inventory, Positive and Negative Affect Scale, and the Alcohol Use Disorders Identification Test and the Drug Abuse Screening Test. Responses were recorded in Research Electronic Data Capture and were analyzed using Microsoft Excel. RESULTS: Fifty-four individuals completed the surveys; 94% were men, 88% black, and 100% victims of interpersonal violence. 85% screened positive for PTSD. VOVs experienced many traumatic events throughout their life. Reported alcohol and drug abuse were low, with 91% at low risk for alcohol use disorders and 92% at low risk for drug abuse disorders (Figure 1). Positive affect remained high, indicating the possibility of resiliency in this population. CONCLUSIONS: PTSD is high in VOVs in urban trauma centers. Understanding the root causes of PTSD can help direct interventions to support individuals with services that meet their individual needs. Simple screening tools can help hospital-based violence intervention programs and trauma social workers identify individual needs and assess risk for mental health and substance abuse disorders.

Bleeding and Thromboembolism After Traumatic Brain Injury in the Elderly: A Real Conundrum.

BACKGROUND: Elderly patients presenting with a traumatic brain injury (TBI) often have comorbidities that increase risk of thromboembolic (TE) disease and recurrent TBI. A significant number are on anticoagulant therapy at the time of injury and studies suggest that continuing anticoagulation can prevent TE events. Understanding bleeding, recurrent TBI, and TE risk after TBI can help to guide therapy. Our objectives were to 1) evaluate the incidence of bleeding, recurrent TBI, and TE events after an initial TBI in older adults and 2) identify which factors contribute to this risk. METHODS: Retrospective analysis of Medicare claims between May 30, 2006 and December 31, 2009 for patients hospitalized with TBI was performed. We defined TBI for the index admission, and hemorrhage (gastrointestinal bleeding or hemorrhagic stroke), recurrent TBI, and TE events (stroke, myocardial infarction, deep venous thrombosis, or pulmonary embolism) over the following year using ICD-9 codes. Unadjusted incidence rates and 95% confidence intervals (CIs) were calculated. Risk factors of these events were identified using logistic regression. RESULTS: Among beneficiaries hospitalized with TBI, incidence of TE events (58.6 events/1000 person-years; 95% CI 56.2, 60.8) was significantly higher than bleeding (23.6 events/1000 person-years; 95% CI 22.2, 25.1) and recurrent TBI events (26.0 events/1000 person-years; 95% CI 24.5, 27.6). Several common factors predisposed to bleeding, recurrent TBI, and TE outcomes. CONCLUSIONS: Among Medicare patients hospitalized with TBI, the incidence of TE was significantly higher than that of bleeding or recurrent TBI. Specific risk factors of bleeding and TE events were identified which may guide care of older adults after TBI.

Impact of Intravenous Immunoglobulin on Survival in Necrotizing Fasciitis With Vasopressor-Dependent Shock: A Propensity Score-Matched Analysis From 130 US Hospitals.

BACKGROUND: Shock frequently complicates necrotizing fasciitis (NF) caused by group A Streptococcus (GAS) or Staphylococcus aureus. Intravenous immunoglobulin (IVIG) is sometimes administered for presumptive toxic shock syndrome (TSS), but its frequency of use and efficacy are unclear. METHODS: Adult patients with NF and vasopressor-dependent shock undergoing surgical debridement from 2010 to 2014 were identified at 130 US hospitals. IVIG cases were propensity-matched and risk-adjusted. The primary outcome was in-hospital mortality and the secondary outcome was median length of stay (LOS). RESULTS: Of 4127 cases of debrided NF with shock at 121 centers, only 164 patients (4%) at 61 centers received IVIG. IVIG subjects were younger with lower comorbidity indices, but higher illness severity. Clindamycin and vasopressor intensity were higher among IVIG cases, as was coding for TSS and GAS. In-hospital mortality did not differ between matched IVIG and non-IVIG groups (crude mortality, 27.3% vs 23.6%; adjusted odds ratio, 1.00 [95% confidence interval, .55-1.83]; P = .99). Early IVIG (≤2 days) did not alter this effect (P = .99). Among patients coded for TSS, GAS, and/or S. aureus, IVIG use was still unusual (59/868 [6.8%]) and lacked benefit (P = .63). Median LOS was similar between IVIG and non-IVIG groups (26 [13-49] vs 26 [11-43]; P = .84). Positive predictive values for identifying true NF and debridement among IVIG cases using our algorithms were 97% and 89%, respectively, based on records review at 4 hospitals. CONCLUSIONS: Adjunctive IVIG was administered infrequently in NF with shock and had no apparent impact on mortality or hospital LOS beyond that achieved with debridement and antibiotics.

Tracking colistin-treated patients to monitor the incidence and outcome of carbapenem-resistant Gram-negative infections.

BACKGROUND: Existing surveillance mechanisms may underestimate the incidence of carbapenem-resistant gram-negative infections (CRGNIs). Although carbapenem resistance increases the risk of death, the trend in mortality over time is unknown. METHODS: A retrospective cohort study was conducted at 40 academic medical centers using a discharge database to identify adult hospital admissions without cystic fibrosis in 2006-2012 and received intravenous colistin for >3 consecutive days or died during therapy (termed colistin cases). The primary outcomes were the number of colistin cases per 100,000 admissions per year and change in the hospital mortality rate over time compared with the rate of discharges to home. Secondary outcomes included median overall and intensive care unit lengths of stay. RESULTS: From 2006 to 2012, a total of 5011 unique patients were identified as colistin cases. The number per 100,000 admissions per year increased from 35.56 to 92.98 during the 7-year study (P < .001). The odds of in-hospital death among colistin cases (compared with discharge to home) decreased by a mean of 5.2%/y (P = .04), whereas discharge to an institution (P = .24) or hospice (P = .89) remained steady over time. The median overall and intensive care unit lengths of stay decreased by 7.5 and 6 days, respectively (P < .001). In a 4-hospital chart review, 81.6% of colistin cases were found to have culture-positive CRGNIs. Conversely, 53% of extensively drug-resistant bloodstream CRGNIs at 2 of these hospitals met colistin case criteria. CONCLUSIONS: Colistin cases represent a severely ill population with a high probability of having culture-confirmed CRGNIs. Colistin tracking is a novel strategy for monitoring the incidence and mortality of CRGNIs, particularly those caused by extensively drug-resistant bacteria. Although the incidence of colistin cases nearly tripled within 7 years, more of these patients are surviving hospitalization and going home.

Defining the acute care surgeon: American Association for the Surgery of Trauma (AAST) panel discussion on full-time employment, compensation and career trajectory.

Since its inception, the specialty of acute care surgery has evolved and now represents a field with a broad clinical scope and large variations in implementation and practice. These variations produce unique challenges and there is no consistent definition of the scope, intensity or value of the work performed by acute care surgeons. This lack of clarity regarding expectations extends to surgeons and non-surgeons outside of our specialty, compounding difficulties in advocacy at the local, regional and national levels. Coupled with a lack of clarity surrounding the definition of full-time employment, these challenges have prompted surgeons to develop initiatives within acute care surgery in collaboration with the American Association for the Surgery of Trauma (AAST). A panel session at the AAST 2023 annual meeting was held to discuss the need to define a full-time equivalent for an acute care surgeon and how to consider and incorporate non-clinical responsibilities. Experiences, perspectives and propositions for change were discussed and are presented here.

Protect and Provide: Perceptions of Manhood and Masculinities Among Disabled Violently Injured Black Men in a Hospital-Based Violence Intervention Program.

Exploring the post-injury lives of those who have survived gunshot wounds is essential to understanding the entire scope of firearm violence. The lives of Black male firearm violence survivors are transformed in various ways due to their injuries both visible and invisible. This study explored how Black men who suffer from disabilities via a firearm negotiated their masculine identities. Semi-structured, qualitative interviews were conducted with 10 violently injured Black men participating in a hospital-based violence intervention program. Survivors expressed their thoughts on how their injuries impacted their manhood and masculinities. Three themes emerged: (1) perceptions of manhood, (2) loss of independence and burden on others, and (3) and mobility. These themes highlighted and described how their lives were impacted post-injury and characterized their psychological and physical experience of recovery. The research findings suggest the need for more qualitative studies to further explore the relationship between firearm injury, Black masculinity, and perceptions of manhood. While Black men are understudied in health research and invisible in disability research, they continue to be hyper-invisible when discussing violently acquired disabilities.

What's missing? Violently injured Black men's narratives around Adverse Childhood Experiences (ACEs).

BACKGROUND: Adverse childhood experiences have been associated with future outcomes; however, Felitti's 1998 ACEs questionnaire fails to capture the experiences of Black populations living in disinvested neighborhoods making it necessary to expand the ACEs questionnaire to examine the life experiences of violently injured Black men. OBJECTIVE: The aim of the study was to advance the understanding of ACEs among Black male firearm violence survivors using the ACEs questionnaire and semi-structured interviews. PARTICIPANTS AND SETTING: Ten Black male firearm violence survivors were recruited from an urban HVIP. Case managers conducted recruitment using the HVIP's REDcap database; active and previous HVIP participants were eligible for the study. METHODS: A qualitative study design was used to understand the childhood experiences of Black male firearm violence survivors using Felitti's ACEs questionnaire and a semi-structured interview examining perceptions of their childhood experiences. Due to the COVID-19 pandemic, recruitment and interviews were conducted over the phone. RESULTS: All participants experienced at least one ACE. Three themes arose from the interviews: youth incarceration, family separation and loss, and housing transition. Men at risk for violent injury experience ACEs beyond those measured in the current instrument.

Complete Transection of the Abdominal Wall Secondary to Being a Rear Seat-Belted Passenger.

Garrett and Braunstein introduced the concept of the "seat belt sign" in motor vehicle collision (MVC) victims. They defined this as abdominal wall bruising from a lap belt. These signs of trauma are not uncommon. However, "seat belt syndrome," a pattern of musculoskeletal and internal organ injuries resulting from deceleration forces exerted by the safety device is rarely seen. Here, we illustrate a case of traumatic closed rupture of the rectus abdominis muscle secondary to seat belt injury. This potential injury is important to recognize and our case will illustrate the need for careful imaging review and clinical assessment to identify associated intra-abdominal injuries.

Characterizing re-triage guidelines: A scoping review of states' rules and regulations.

BACKGROUND: State guidelines for re-triage, or emergency inter-facility transfer, have never been characterized across the United States. METHODS: All 50 states' Department of Health and/or Trauma System websites were reviewed for publicly available re-triage guidelines within their rules and regulations. Communication was made via phone or email to state agencies or trauma advisory committees to obtain or confirm the absence of guidelines where public data was unavailable. Guideline criteria were abstracted and grouped into domains of Center for Disease Control Field Triage Criteria: pattern/anatomy of injury, vital signs, special populations, and mechanisms of injury. Re-triage criteria were summarized across states using median and interquartile ranges for continuous data and frequencies for categorical data. Demographic data of states with and without re-triage guidelines were compared using the Wilcoxon rank sum test. RESULTS: Re-triage guidelines were identified for 22 of 50 states (44%). Common anatomy of injury criteria included head trauma (91% of states with guidelines), spinal cord injury (82%), chest injury (77%), and pelvic injury (73%). Common vital signs criteria included Glasgow Coma Score (91% of states) ranging from 8 to 14, systolic blood pressure (36%) ranging from 90 to 100 mm Hg, and respiratory rate (23%) with all using 10 respirations/minute. Common special populations criteria included mechanical ventilation (73% of states), age (68%) ranging from <2 or >60 years, cardiac disease (59%), and pregnancy (55%). No significant demographic differences were found between states with versus without re-triage guidelines. CONCLUSION: A minority of US states have re-triage guidelines. Characterizing existing criteria can inform future guideline development.

ACR Appropriateness Criteria® Penetrating Torso Trauma.

This document assesses the appropriateness of various imaging studies for acute penetrating trauma to the torso. Penetrating trauma most commonly occurs from gunshots and stabbings, although any object can impale the patient. Anatomic location, type of penetrating trauma, and hemodynamic status are among the many important factors when deciding upon if, what, and when imaging is needed to further evaluate the patient. Imaging plays a critical role in the management of these patients. CT, in particular, aids in identifying and predicting internal injuries based upon trajectory of the object. Clinical variants are distinguished by ballistic versus nonballistic injuries, hemodynamic status, and compartment of the body injured. Ballistic trauma trajectory is less predictable, and imaging recommendations are adjusted for this unpredictability. Excluded from this document are penetrating traumatic injuries to pediatric patients and specific recommendations when the genitourinary system is clinically suspected to be injured, the latter of which is more specifically discussed in other Appropriateness Criteria documents. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are documented annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer documented journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer documented literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.
