RESUMEN

Numerous surgical advances have resulted from exchanges between military and civilian surgeons. As part of the U.S. National Library of Medicine Michael E. DeBakey Fellowship in the History of Medicine, we conducted archival research to shed light on the lessons that civilian surgery has learned from the military system and vice-versa. Several historical case studies highlight the need for immersive programs where surgeons from the military and civilian sectors can gain exposure to the techniques, expertise, and institutional knowledge the other domain provides. Our findings demonstrate the benefits and promise of structured programs to promote reciprocal learning between military and civilian surgery.

RESUMEN

OBJECTIVE: We sought to determine whether state firearm legislation correlated with firearm-related fatality rates (FFR) during a 15-year period. BACKGROUND: The politicized and controversial topic of firearm legislation has been grossly understudied when the relative impact of American firearm violence is considered. Scientific evidence regarding gun legislation effectiveness remains scant. METHODS: Demographic and intent data (1999-2013) were collected from the Centers for Disease Control and Prevention's Web-Based Injury Statistics Query and Reporting System database and compared by state firearm legislation rankings with respect to FFR. State scorecards were obtained from firearm-restrictive (Brady Campaign/Law Center against Gun Violence [BC/LC]) and less-restrictive (National Rifle Association) groups. FFR were compared between restrictive and least-restrictive states during 3 periods (1999-2003, 2004-2008, 2009-2013). RESULTS: During 1999 to 2013, 462,043 Americans were killed by firearms. Overall FFR did not change during the 3 periods (10.89 ±â€Š3.99/100,000; 10.71 ±â€Š3.93/100,000; 11.14 ±â€Š3.91/100,000; P = 0.87). Within each period, least-restrictive states had greater unintentional, pediatric, and adult suicide, White and overall FFR than restrictive states (all P < 0.05). Conversely, no correlation was seen, during any of the 3 time periods, with either homicide or Black FFR-population subsets accounting for 41.7% of firearm deaths. CONCLUSIONS: Restrictive firearm legislation is associated with decreased pediatric, unintentional, suicide, and overall FFR, but homicide and Black FFR appear unaffected. Future funding and research should be directed at both identifying the most effective aspects of firearm legislation and creating legislation that equally protects every segment of the American population.

RESUMEN

Advanced practitioners (APs) have been successfully integrated into the clinical care of injured patients. Given the expanding role of APs in trauma care, we hypothesized that APs can perform Performance Improvement and Patient Safety (PIPS) peer review at a level comparable with trauma surgeons. For Phase 1, cases previously reviewed by a trauma surgeon were randomly selected by the PIPS coordinator and peer reviewed by an AP. The trauma surgeons' and APs' reviews were compared. For Phase 2, cases requiring concurrent review were peer reviewed by both an AP and an MD, who were blinded to each other's review. Both the APs' and trauma surgeons' reviews of the same medical record were presented at a bimonthly performance improvement (PI) meeting. In Phase 1, 46 PI cases were reviewed including 22 deaths. Trauma surgeons and APs had high concordance (96.0%) regarding appropriateness or inappropriateness of care (κ = 0.774). Among disagreements, APs were 3 times more likely than trauma surgeons to determine care to be inappropriate. Trauma surgeons and APs had similarly high concordance (95.5%) regarding preventability of mortality (κ = 0.861). In Phase 2, 38 PI cases were reviewed, including 31 deaths. Trauma surgeons and APs had high concordance (89.0%) regarding appropriateness or inappropriateness of care (κ = 0.585). Among disagreements, trauma surgeons and APs had similarly high concordance (86.2%) regarding preventability of mortality (κ = 0.266). We found that APs had high concordance with trauma surgeons regarding medical record reviews and are thus able to effectively review medical records for the purposes of PIPS.

RESUMEN

BACKGROUND: Top-tier general and specialty scientific journals serve as a bellwether for national research priorities. We hypothesize that military-relevant publications are underrepresented in the scientific literature and that such publications decrease significantly during peacetime. METHODS: We identified high impact journals in the fields of Medicine, Surgery and Critical Care and developed Boolean searches for military-focused topics using National Library of Medicine Subject Headings terms. A PubMed search from 1950 to 2020 returned the number of research publications in relevant journals and the rate of military-focused publications by year. Rates of military publications were compared between peacetime and wartime. Publication rate trends were modeled with a quadratic function controlling for the start of active conflict and total casualty numbers. Baseline proportions of military physicians relative to the civilian sector served to estimate expected publication rates. Comparisons were performed using Pearson's Chi Square and Mann-Whitney U test, with p < 0.05 considered a significant difference. RESULTS: From 1950 to 2020, a total of 716,340 manuscripts were published in the journals queried. Of these, military-relevant manuscripts totaled 4,052 (0.57%). We found a significant difference in the rate of publication during times of peace and times of war (0.40% vs. 0.69%, p < 0.001). Subgroup analysis found significantly reduced rates of publication in medical and critical care journals during peacetime. For each conflict, the percentage of military-focused publications peaked during periods of war but then receded below baseline levels within a median of 2.5 years (interquartile range 1.5-3.8 years) during peacetime. The proportion of military-focused publications never reached the current proportion of military physicians in the workforce. CONCLUSION: There is marked reduction in rates of publication for military-focused articles in high impact journals during peacetime. Military-focused articles are underrepresented in high-impact journals. Investigators of military-relevant topics and editors of high-impact journals should seek to close this gap.

RESUMEN

BACKGROUND: The care and outcome of enterocutaneous fistula (ECF) have improved greatly over several decades due to revolutionary advances in nutrition, along with dramatic improvements in the treatment of sepsis and the critically ill. However, as the collective experience with damage control surgery has matured, the frequent development of enteroatmospheric fistula (EAF) in the "open abdomen" patient has emerged as an even more vexing problem. Despite our best efforts, ECF and especially EAF continue to be highly morbid conditions, and sepsis and malnutrition remain the leading causes of death. Aggressive nutritional and metabolic support is the most significant predictor of outcome with ECF and EAF. RESULTS: Discussion of the historical advances in nutritional therapy and their impact on ECF, as well as review of the classification of ECF and EAF, provides a framework for the suggested phased strategy that specifically targets the nutritional and metabolic needs of the ECF/EAF patient. These three phases include (1) diagnosis, resuscitation, and early interval nutrition; (2) definition of fistula anatomy, drainage of collections, nutritional assessment and monitoring, and placement of feeding access; and (3) definitive nutritional management, including pharmacologic adjuncts. Early nutritional support with parenteral nutrition followed by transition to enteral nutrition is advocated, including the merits of delivery of enteral nutrition via the fistula itself, known as fistuloclysis. CONCLUSION: Aggressive nutritional therapy is necessary to reverse the catabolic state associated with ECF/EAF patients. Once established, it allows proper time, preparation, and planning for definitive management of the fistula, and in many cases provides the support for spontaneous closure.

RESUMEN

The global response to the 12 January 2010 earthquake in Haiti revealed the ability to mobilise medical teams quickly and effectively when academic medical centres partner non-governmental organisations (NGO) that already have a presence in a zone of devastation. Most established NGOs based in a certain region are accustomed to managing the medical conditions that are common to that area and will need additional and specialised support to treat the flux of myriad injured persons. Furthermore, an NGO with an established presence in a region prior to a disaster appears better positioned to provide sustained recovery and rehabilitation relief. Academic medical centres can supply these essential specialised resources for a prolonged time. This relationship between NGOs and academic medical centres should be further developed prior to another disaster response. This model has great potential with regard to the rapid preparation and worldwide deployment of skilled medical and surgical teams when needed following a disaster, as well as to the subsequent critical recovery phase.

RESUMEN

BACKGROUND: Trauma center mortality rates are benchmarked to expected rates of death based on patient and injury characteristics. The expected mortality rate is recalculated from pooled outcomes across a trauma system each year, obscuring system-level change across years. We hypothesized that risk-adjusted mortality would decrease over time within a state-wide trauma system. METHODS: We identified adult trauma patients presenting to Level I and II Pennsylvania trauma centers, 1999-2018, using the Pennsylvania Trauma Outcomes Study. Multivariable logistic regression generated risk-adjusted models for mortality in all patients, and in key subgroups: penetrating torso injury, blunt multisystem trauma, and patients presenting in shock. RESULTS: Of 162,646 included patients, 123,518 (76.1%) were white and 108,936 (67.0%) were male. The median age was 49 (interquartile range [IQR] 29-70), median injury severity score was 16 (IQR 10-24), and 87.5% of injuries were blunt. Overall, 9.9% of patients died, and compared to 1999, no year had significantly higher adjusted odds of mortality. Overall mortality was significantly lower in 2007-2009 and 2011-2018. Of patients with blunt, multisystem injuries, 17.7% died, and adjusted mortality improved over time. Mortality rates were 24.9% for penetrating torso injury, and 56.9% for shock, with no significant change. Mortality improved for patients with ISS < 25, but not for the most severely injured. CONCLUSIONS: Over 20 years, Pennsylvania trauma centers demonstrated improved risk-adjusted mortality rates overall, but improvement remains lacking in high-risk groups despite numerous innovations and practice changes in this time period. Identifying change over time can help guide focus to these critical gaps.

RESUMEN

Importance: The burden of firearm violence in US cities continues to rise. The role of access to trauma center care as a trauma system measure with implications for firearm injury mortality has not been comprehensively evaluated. Objective: To evaluate the association between geospatial access to care and firearm injury mortality in an urban trauma system. Design, Setting, and Participants: Retrospective cohort study of all people 15 years and older shot due to interpersonal violence in Philadelphia, Pennsylvania, between January 1, 2015, and August 9, 2021. Exposures: Geospatial access to care, defined as the predicted ground transport time to the nearest trauma center for each person shot, derived by geospatial network analysis. Main Outcomes and Measures: Risk-adjusted mortality estimated using hierarchical logistic regression. The population attributable fraction was used to estimate the proportion of fatalities attributable to disparities in geospatial access to care. Results: During the study period, 10 105 people (910 [9%] female and 9195 [91%] male; median [IQR] age, 26 [21-28] years; 8441 [84%] Black, 1596 [16%] White, and 68 other [<1%], including Asian and unknown, consolidated owing to small numbers) were shot due to interpersonal violence in Philadelphia. Of these, 1999 (20%) died. The median (IQR) predicted transport time was 5.6 (3.8-7.2) minutes. After risk adjustment, each additional minute of predicted ground transport time was associated with an increase in odds of mortality (odds ratio [OR], 1.03 per minute; 95% CI, 1.01-1.05). Calculation of the population attributable fraction using mortality rate ratios for incremental 1-minute increases in predicted ground transport time estimated that 23% of shooting fatalities could be attributed to differences in access to care, equivalent to 455 deaths over the study period. Conclusions and Relevance: These findings indicate that geospatial access to care may be an important trauma system measure, improvements to which may result in reduced deaths from gun violence in US cities.

RESUMEN

Hemorrhage, and particularly noncompressible torso hemorrhage remains a leading cause of potentially preventable prehospital death from trauma in the United States and globally. A subset of severely injured patients either die in the field or develop irreversible hemorrhagic shock before they can receive hospital definitive care, resulting in poor outcomes. The focus of this opinion paper is to delineate (a) the need for existing trauma systems to adapt so that potentially life-saving advanced resuscitation and truncal hemorrhage control interventions can be delivered closer to the point-of-injury in select patients, and (b) a possible mechanism through which some trauma systems can train and incorporate select prehospital advanced resuscitative care teams to deliver those interventions.

RESUMEN

PURPOSE: High-grade renal injuries have traditionally been treated operatively. Alternatively, embolotherapy is used to control hemorrhage, but there are few studies that validate this practice after renal injury. Embolotherapy may offer an effective and safe means to arrest hemorrhage after high-grade blunt renal injury. MATERIALS AND METHODS: Retrospective analysis was performed of high-grade renal injury (grade III or higher). Patients who were initially treated with arteriography were compared with those who underwent surgery. Statistical analysis was performed with Wilcoxon rank-sum and χ(2) tests. RESULTS: Sixty-nine patients were identified, 28 of whom had contrast agent extravasation on computed tomography (CT). Of these 69 patients, 17 underwent operation and 20 underwent arteriography. The surgical cohort had a higher injury severity score (39.6 vs 24.2; P < .01), but there was no difference in renal injury grade (P = .9). The arteriography cohort received significantly more contrast medium (P < .001). Contrast agent extravasation was confirmed angiographically in six of 12 patients who had this finding on CT, and embolotherapy controlled bleeding in all six. No significant difference was noted in transfusion need, recurrent hemorrhage, creatinine level at discharge, glomerular filtration rate, or length of stay (P > .4 for each endpoint). There was a trend toward a longer stay in the intensive care unit in the surgical cohort and a higher likelihood of discharge to home in the arteriography group (P = .08 for each endpoint). CONCLUSIONS: Embolotherapy offers a safe means to diagnose and arrest hemorrhage after renal injury. The additional contrast agent needed for imaging does not increase the incidence of nephropathy irrespective of renal injury grade.

RESUMEN

BACKGROUND: Brain tissue oxygenation (PbtO2)-guided management facilitates treatment of reduced PbtO2 episodes potentially conferring survival and outcome advantages in severe traumatic brain injury (TBI). To date, the nature and effectiveness of commonly used interventions in correcting compromised PbtO2 in TBI remains unclear. We sought to identify the most common interventions used in episodes of compromised PbtO2 and to analyze which were effective. METHODS: A retrospective 7-year review of consecutive severe TBI patients with a PbtO2 monitor was conducted in a Level I trauma center's intensive care unit or neurosurgical registry. Episodes of compromised PbtO2 (defined as <20 mm Hg for 0.25-4 hours) were identified, and clinical interventions conducted during these episodes were analyzed. Response to treatment was gauged on how rapidly (ΔT) PbtO2 normalized (>20 mm Hg) and how great the PbtO2 increase was (ΔPbtO2). Intracranial pressure (ΔICP) and cerebral perfusion pressure (ΔCPP) also were examined for these episodes. RESULTS: Six hundred twenty-five episodes of reduced PbtO2 were identified in 92 patients. Patient characteristics were: age 41.2 years, 77.2% men, and Injury Severity Score and head or neck Abbreviated Injury Scale score of 34.0 ± 9.2 and 4.9 ± 0.4, respectively. Five interventions: narcotics or sedation, pressors, repositioning, FIO2/PEEP increases, and combined sedation or narcotics + pressors were the most commonly used strategies. Increasing the number of interventions resulted in worsening the time to PbtO2 correction. Triple combinations resulted in the lowest ΔICP and dual combinations in the highest ΔCPP (p < 0.05). CONCLUSION: Clinicians use a limited number of interventions when correcting compromised PbtO2. Using strategies employing many interventions administered closely together may be less effective in correcting PbO2, ICP, and CPP deficits. Some PbtO2 deficits may be self-limited.

RESUMEN

BACKGROUND: The earthquake that struck Haiti on 10 January 2010, killed 200,000 persons and injured thousands more. Working with Partners in Health, a non-governmental organization already present in Haiti, Dartmouth College, and the University of Pennsylvania sent multidisciplinary surgical teams to hospitals in the villages of Hinche and Cange. The purpose of this report is to describe the injuries seen and evolution of treatments rendered at these two outlying regional hospitals during the first month following the earthquake. METHODS: A retrospective review of the database maintained by each team was performed. In addition to a list of equipment taken to Haiti, information collected included patient age, American Society of Anesthesiology (ASA) physical status, injuries sustained, procedures performed, wound management strategy, antibiotic therapy, and early outcomes. RESULTS: A total of 113 surgical procedures were performed in 15 days by both teams. The average patient age was 25 years and average ASA score was 1.4. The majority of injuries involved large soft tissue wounds and closed fractures, although 21-40% of the patients at each hospital had either an open fracture or amputation wound. Initially, wound debridement was the most common procedure performed, but after two weeks, skin grafting, fracture fixation, and amputation revision were the more commonly needed operations. CONCLUSIONS: Academic surgical teams can ameliorate the morbidity and mortality following disasters caused by natural hazards by partnering with organizations that already have a presence in the affected region. A multidisciplinary team of surgeons and nurses can improve both mortality and morbidity following a disaster.

RESUMEN

BACKGROUND: Acute traumatic coagulopathy often accompanies traumatic brain injury (TBI) and may impair cognitive recovery. Antithrombin III (AT-III) reduces the hypercoagulability of TBI. Antithrombin III and heparinoids such as enoxaparin (ENX) demonstrate potent anti-inflammatory activity, reducing organ injury and modulating leukocyte (LEU) activation, independent of their anticoagulant effect. It is unknown what impact AT-III exerts on cerebral LEU activation and blood-brain barrier (BBB) permeability after TBI. We hypothesized that AT-III reduces live microcirculatory LEU-endothelial cell (EC) interactions and leakage at the BBB following TBI. METHODS: CD1 mice (n = 71) underwent either severe TBI (controlled cortical impact (CCI), 6-m/s velocity, 1-mm depth, and 4-mm diameter) or sham craniotomy and then received either AT-III (250 IU/kg), ENX (1.5 mg/kg), or vehicle (saline) every 24 hours. Forty-eight hours post-TBI, cerebral intravital microscopy visualized in vivo penumbral microvascular LEU-EC interactions and microvascular leakage to assess BBB inflammation/permeability. Body weight loss and the Garcia neurological test (motor, sensory, reflex, balance) served as surrogates of clinical recovery. RESULTS: Both AT-III and ENX similarly reduced in vivo penumbral LEU rolling and adhesion (p < 0.05). Antithrombin III also reduced live BBB leakage (p < 0.05). Antithrombin III animals demonstrated the least 48-hour body weight loss (8.4 ± 1%) versus controlled cortical impact and vehicle (11.4 ± 0.5%, p < 0.01). Garcia neurological test scores were similar among groups. CONCLUSION: Antithrombin III reduces post-TBI penumbral LEU-EC interactions in the BBB leading to reduced neuromicrovascular permeability. Antithrombin III further reduced body weight loss compared with no therapy. Further study is needed to determine if these AT-III effects on neuroinflammation affect longer-term neurocognitive recovery after TBI.

RESUMEN

BACKGROUND: Public health measures were instituted to reduce COVID-19 spread. A decrease in total emergency department volume followed, but the impact on injury is unknown. With lockdown and social distancing potentially increasing domicile discord, we hypothesized that intentional injury increased during COVID-19, driven primarily by an increase in penetrating trauma. STUDY DESIGN: A retrospective review of acute adult patient care in an urban Level I trauma center assessed injury patterns. Presenting patient characteristics and diagnoses from 6 weeks pre to 10 weeks post statewide stay-at-home orders (March 16, 2020) were compared, as well as with 2015-2019. Subsets were defined by intentionality (intentional vs nonintentional) and mechanism of injury (blunt vs penetrating). Fisher exact and Wilcoxon tests were used to compare proportions and means. RESULTS: There were 357 trauma patients that presented pre stay-at-home order and 480 that presented post stay-at-home order. Pre and post groups demonstrated differences in sex (35.6% vs 27.9% female; p = 0.02), age (47.4 ± 22.1 years vs 42 ± 20.3 years; p = 0.009), and race (1.4% vs 2.3% Asian; 63.3% vs 68.3% Black; 30.5% vs 22.3% White; and 4.8% vs 7.1% other; p = 0.03). Post stay-at-home order mechanism of injury revealed more intentional injury (p = 0.0008). Decreases in nonintentional trauma after adoption of social isolation paralleled declines in daily emergency department visits. Compared with earlier years, 2020 demonstrated a significantly greater proportion of intentional violent injury during the peripandemic months, especially from firearms. CONCLUSIONS: Unprecedented social isolation policies to address COVID-19 were associated with increased intentional injury, especially gun violence. Meanwhile, emergency department and nonintentional trauma visits decreased. Pandemic-related public health measures should embrace intentional injury prevention and management strategies.

RESUMEN

BACKGROUND: On Tuesday, January 12, 2010 at 16:53 local time, a magnitude 7.0 M(w) earthquake struck Haiti. The global humanitarian attempt to respond was swift, but poor infrastructure and emergency preparedness limited many efforts. Rapid, successful deployment of emergency medical care teams was accomplished by organizations with experience in mass disaster casualty response. Well-intentioned, but unprepared, medical teams also responded. In this report, we describe the preparation and planning process used at an academic university department of anesthesiology with no preexisting international disaster response program, after a call from an American-based nongovernmental organization operating in Haiti requested medical support. The focus of this article is the pre-deployment readiness process, and is not a post-deployment report describing the medical care provided in Haiti. METHODS: A real-time qualitative assessment and systematic review of the Hospital of the University of Pennsylvania's communications and actions relevant to the Haiti earthquake were performed. Team meetings, conference calls, and electronic mail communication pertaining to planning, decision support, equipment procurement, and actions and steps up to the day of deployment were reviewed and abstracted. Timing of key events was compiled and a response timeline for this process was developed. Interviews with returning anesthesiology members were conducted. RESULTS: Four days after the Haiti earthquake, Partners in Health, a nonprofit, nongovernmental organization based in Boston, Massachusetts, with >20 years of experience providing medical care in Haiti contacted the University of Pennsylvania Health System to request medical team support. The departments of anesthesiology, surgery, orthopedics, and nursing responded to this request with a volunteer selection process, vaccination program, and systematic development of equipment lists. World Health Organization and Centers for Disease Control guidelines, the American Society of Anesthesiology Committee on Trauma and Emergency Preparedness, published articles, and in-country contacts were used to guide the preparatory process. CONCLUSION: An organized strategic response to medical needs after an international natural disaster emergency can be accomplished safely and effectively within 6 to 12 days by an academic anesthesiology department, with medical system support, in a center with no previously established response system. The value and timeliness of this response will be determined with further study. Institutions with limited experience in putting an emergency medical team into the field may be able to quickly do so when such efforts are executed in a systematic manner in coordination with a health care organization that already has support infrastructure at the site of the disaster.

RESUMEN

BACKGROUND: Federal law requires background checks for firearms purchased from licensed dealers, but states can extend requirements to private sales of handguns and purchases at gun shows (universal background checks for handguns [UBC-HG]). Although firearm homicide disproportionately affects African Americans, little is known about how UBG-HG impacts African Americans. We hypothesized that implementation of UBC-HG would reduce rates of firearm homicide of African Americans. METHODS: We collected Centers for Disease Control firearm homicide counts for African American and white populations in the 50 states, 1999 to 2017. Laws were drawn from the State Firearm Laws Database. The exposure and outcome of interest were UBC-HG adoption and firearm homicide. We included non-Hispanic African American and non-Hispanic white populations. We used Poisson regression to perform a differences-in-differences analysis. A categorical variable for state accounted for time-stable state characteristics. We controlled for year to account for trends over time unrelated to policy. We controlled for state-specific, time-variable factors, including median household income, population younger than 25 years or 65 years or older, alcohol consumption, and count of firearm laws (UBC-HG excluded). Standard errors were adjusted for clustering at the state level. RESULTS: The firearm homicide rate among whites was 1.8 per 100,000 (interquartile range, 1.2-2.7) ranging from 1.4 in 2011 to 1.8 in 2016. The firearm homicide rate was 15.6 per 100,000 (interquartile range, 11.6-21.0) among African Americans, ranging from 14.0 in 2009 to 19.6 in 2017. While no significant difference in firearm homicides among whites (incidence rate ratio, 0.93; 95% confidence interval, 0.73-1.20) was appreciated, the passage of UBC-HG was associated with an 19% decrease in African Americans firearm homicides (incidence rate ratio, 0.81; 95% confidence interval, 0.70-0.94; p = 0.006). CONCLUSION: Implementing UBC-HG was associated with decreased firearm homicides among African Americans-the population most at risk. Expanding UBC-HG may be an effective approach to reducing racial disparities in firearm homicides. LEVEL OF EVIDENCE: Epidemiological, level III.

RESUMEN

Importance: The outcomes of firearm injuries in the United States are devastating. Although firearm mortality and costs have been investigated, the long-term outcomes after surviving a gunshot wound (GSW) remain unstudied. Objective: To determine the long-term functional, psychological, emotional, and social outcomes among survivors of firearm injuries. Design, Setting, and Participants: This prospective cohort study assessed patient-reported outcomes among GSW survivors from January 1, 2008, through December 31, 2017, at a single urban level I trauma center. Attempts were made to contact all adult patients (aged ≥18 years) discharged alive during the study period. A total of 3088 patients were identified; 516 (16.7%) who died during hospitalization and 45 (1.5%) who died after discharge were excluded. Telephone contact was made with 263 (10.4%) of the remaining patients, and 80 (30.4%) declined study participation. The final study sample consisted of 183 participants. Data were analyzed from June 1, 2018, through June 20, 2019. Exposures: A GSW sustained from January 1, 2008, through December 31, 2017. Main Outcomes and Measures: Scores on 8 Patient-Reported Outcomes Measurement Information System (PROMIS) instruments (Global Physical Health, Global Mental Health, Physical Function, Emotional Support, Ability to Participate in Social Roles and Activities, Pain Intensity, Alcohol Use, and Severity of Substance Use) and the Primary Care PTSD (posttraumatic stress disorder) Screen for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Results: Of the 263 patients who survived a GSW and were contacted, 183 (69.6%) participated. Participants were more likely to be admitted to the hospital compared with those who declined (150 [82.0%] vs 54 [67.5%]; P = .01). Participants had a median time from GSW of 5.9 years (range, 4.7-8.1 years) and were primarily young (median age, 27 years [range, 21-36 years]), black (168 [91.8%]), male (169 [92.3%]), and employed before GSW (pre-GSW, 139 [76.0%]; post-GSW, 113 [62.1%]; decrease, 14.3%; P = .004). Combined alcohol and substance use increased by 13.2% (pre-GSW use, 56 [30.8%]; post-GSW use, 80 [44.0%]). Participants had mean (SD) scores below population norms (50 [10]) for Global Physical Health (45 [11]; P < .001), Global Mental Health (48 [11]; P = .03), and Physical Function (45 [12]; P < .001) PROMIS metrics. Eighty-nine participants (48.6%) had a positive screen for probable PTSD. Patients who required intensive care unit admission (n = 64) had worse mean (SD) Physical Function scores (42 [13] vs 46 [11]; P = .045) than those not requiring the intensive care unit. Survivors no more than 5 years after injury had greater PTSD risk (38 of 63 [60.3%] vs 51 of 119 [42.9%]; P = .03) but better mean (SD) Global Physical Health scores (47 [11] vs 43 [11]; P = .04) than those more than 5 years after injury. Conclusions and Relevance: This study's results suggest that the lasting effects of firearm injury reach far beyond mortality and economic burden. Survivors of GSWs may have negative outcomes for years after injury. These findings suggest that early identification and initiation of long-term longitudinal care is paramount.

RESUMEN

BACKGROUND: Historically, patients with penetrating cardiac injuries have enjoyed the best survival after emergency department thoracotomy (EDT), but further examination of these series reveals a preponderance of cardiac stab wound (SW) survivors with only sporadic cardiac gunshot wound (GSW) survivors. Our primary study objective was to determine which patients requiring EDT for penetrating cardiac or great vessel (CGV) injury are salvageable. METHODS: All patients who underwent EDT for penetrating CGV injuries in two urban, level I trauma centers during 2000 to 2007 were retrospectively reviewed. Demographics, injury (mechanism, anatomic injury), prehospital care, and physiology (signs of life [SOL], vital signs, and cardiac rhythm) were analyzed with respect to hospital survival. RESULTS: The study population (n = 283) comprised young (mean age, 27.1 years +/- 10.1 years) men (96.1%) injured by gunshot (GSW, 88.3%) or SWs (11.7%). Patients were compared by injury mechanism and number of CGV wounds with respect to survival (SW, 24.2%; GSW, 2.8%; p < 0.001; single, 9.5%; multiple, 1.4%; p = 0.003). Three predictors-injury mechanism, ED SOL, and number of CGV wounds-were then analyzed alone and in combination with respect to hospital survival. Only one patient (0.8%) with multiple CGV GSW survived EDT. CONCLUSION: When the cumulative impact of penetrating injury mechanism, ED SOL, and number of CGV wounds was analyzed together, we established that those sustaining multiple CGV GSWs (regardless of ED SOL) were nearly unsalvageable. These results indicate that when multiple CGV GSWs are encountered after EDT, further resuscitative efforts may be terminated without limiting the opportunity for survival.

RESUMEN

BACKGROUND: Trauma centers are increasingly tasked with evaluating patients who have sustained low-acuity mechanisms of injury, such as fall from standing (FFS). Previous studies have shown that low-level falls are associated with a high incidence of injury in certain patient groups. The purpose of the current study was to assess risk factors associated with brain injury and death after fall from the standing position only. MATERIALS: A retrospective analysis was performed on all patients who presented with FFS as the mechanism of injury from 2000 to 2005. Demographic variables, past medical history, use of warfarin, blood-alcohol level, initial vital signs, injuries, disposition, and mortality outcome were recorded. Data were analyzed to determine risk factors associated with brain injury, need for intensive care unit (ICU) admission, need for emergency operation, and mortality. RESULTS: A total of 808 patients were identified. Risk factors associated with brain injury, the need for ICU admission, and death included: Injury Severity Score, age >or=60 years, blood-alcohol level greater than 80 mg/dL, warfarin use, systolic blood pressure <100 mm Hg, and Glasgow Coma Scale
