Therapeutic Interventions and Outcomes in Civilian and Military Isolated Gunshot Wounds to the Head: A Department of Defense Trauma Registry and ACS TQIP-matched Study.

OBJECTIVE: The purpose of this study was to compare therapeutic strategies and outcomes, following isolated gunshot wounds of the head, between military and civilian populations. BACKGROUND: Recent military conflicts introduced new concepts in trauma care, including aggressive surgical intervention in severe head trauma. METHODS: This was a cohort-matched study, using the civilian Trauma Quality Improvement Program (TQIP) database of the American College of Surgeons (ACS) and the Department of Defense Trauma Registry (DoDTR), during the period 2013 to 2016. Included in the study were patients with isolated gunshots to the head. Exclusion criteria were dead on arrival, civilians transferred from other hospitals, and patients with major extracranial associated injuries (body area Abbreviated Injury Scale >3). Patients in the military database were propensity score-matched 1:3 with patients in the civilian database. RESULTS: A total of 136 patients in the DoDTR database were matched for age, sex, year of injury, and head Abbreviated Injury Scale with 408 patients from TQIP. Utilization of blood products was significantly higher in the military population ( P <0.001). In the military group, patients were significantly more likely to have intracranial pressure monitoring (17% vs 6%, P <0.001) and more likely to undergo craniotomy or craniectomy (34% vs 13%, P <0.001) than in the civilian group. Mortality in the military population was significantly lower (27% vs 38%, P =0.013). CONCLUSIONS: Military patients are more likely to receive blood products, have intracranial pressure monitoring and undergo craniectomy or craniotomy than their civilian counterparts after isolated head gunshot wounds. Mortality is significantly lower in the military population. LEVEL OF EVIDENCE: Level III-therapeutic.

Safety of Pressurized Intraosseous Blood Infusion Strategies in a Swine Model of Hemorrhagic Shock.

BACKGROUND: Current guidelines support intraosseous access for trauma resuscitation when intravenous access is not readily available. However, safety of intraosseous blood transfusions with varying degrees of infusion pressure has not been previously characterized. MATERIALS AND METHODS: Adult female Yorkshire swine (Sus scrofa; n = 36; mean (M): 80 kg, 95% CI: 78-82 kg) were cannulated and then bled approximately 30% total blood volume. Swine were randomly assigned to proximal humerus intraosseous blood infusion with either Rapid Infuser, or Pressure Bag, or Push-Pull methods (n = 12 each). Flow rates, infusion pressures, vitals, biochemical variables, and pulmonary and renal tissue pathology were contrasted between groups. RESULTS: Flow rates were greater for the Push-Pull strategy than Pressure Bag (96.5 mL/min versus 72.6 mL/min, P = 0.02) or Rapid Infuser (96.5 mL/min versus 60 mL/min, P = 0.002) strategies. The pressures generated during the Push-Pull transfusion (3058 mmHg) were greater than the other strategies (≤360 mmHg). After the observation period, plasma-free hemoglobin levels were higher in the Push-Pull strategy than in the Rapid Infuser (40 mg/dL versus 12 mg/dL, P = 0.02) or Pressure Bag (40 mg/dL versus 12 mg/dL, P = 0.01). Groups did not significantly differ in vitals, biochemical variables, or tissue pathology. CONCLUSIONS: Push-Pull conferred the highest flow rates, but with higher infusion pressures and evidence of intravascular hemolysis. Rapid Infuser and Pressure Bag infusions had no increase from baseline in plasma-free hemoglobin. Pressure Bag infusion was noted to confer an advantage in flow rates over Rapid Infuser. Intraosseous blood transfusion with pressure bags can safely bridge toward central access in the early phases of trauma resuscitation.

Building capacity for ATLS trauma education: role of nurse practitioners and physician assistants.

Objectives: Advanced Trauma Life Support (ATLS) focuses on care of injured patients in the first hour of resuscitation. Expanded demand for courses has led to a concurrent need for new instructors. Nurse practitioners and physician assistants (NPs/PAs) work on trauma services and duties include patient, staff, and outreach education. The goal of this project was to assess NP/PA self-reported knowledge and skills pertinent to ATLS and identify potential barriers to becoming instructors. Materials: This was a voluntary 91-question survey emailed to NP/PA lists obtained from professional societies and online social media channels. NPs/PAs completed a survey reflecting self-reported knowledge, experience, comfort level, and barriers to teaching ATLS interactive discussions and skills. Responses were recorded using a Likert scale and results were documented as percentages. Number of years of experience versus perceived knowledge and comfort teaching were compared using a χ2 test of independence. Results: There were 1696 completed surveys. Most NPs/PAs thought they had adequate knowledge and experience to teach interactive discussions and skills. Those with more years of experience and those who completed more ATLS courses had higher percentages. The number 1 barrier to teaching was lack of formal teaching experience followed by perceived hierarchy concerns. Experience and comfort with skills that fell below 50% were pediatric airway (49.5%), needle and surgical cricothyrotomy (49.8% and 44.8%), diagnostic peritoneal lavage (21.6%), and venous cutdown (20.8%). Conclusion: NPs/PAs with experience in trauma reported having the knowledge and skill to teach ATLS. A majority are comfortable teaching interactive discussions and skills for which they are knowledgeable. The primary barrier to teaching was lack of formal teaching experience, which is covered in the ATLS Instructor course. Training NPs/PAs to become instructors would increase the instructor base and allow for increased promulgation of ATLS and trauma education. Level of evidence: IV.

Committee on Surgical Combat Casualty Care position statement: Neurosurgical capability for the optimal management of traumatic brain injury during deployed operations.

BACKGROUND: Experiences over the last three decades of war have demonstrated a high incidence of traumatic brain injury (TBI) resulting in a persistent need for a neurosurgical capability within the deployed theater of operations. Despite this, no doctrinal requirement for a deployed neurosurgical capability exists. Through an iterative process, the Joint Trauma System Committee on Surgical Combat Casualty Care (CoSCCC) developed a position statement to inform medical and nonmedical military leaders about the risks of the lack of a specialized neurosurgical capability. METHODS: The need for deployed neurosurgical capability position statement was identified during the spring 2021 CoSCCC meeting. A triservice working group of experienced forward-deployed caregivers developed a preliminary statement. An extensive iterative review process was then conducted to ensure that the intended messaging was clear to senior medical leaders and operational commanders. To provide additional context and a civilian perspective, statement commentaries were solicited from civilian clinical experts including a recently retired military trauma surgeon boarded in neurocritical care, a trauma surgeon instrumental in developing the Brain Injury Guidelines, a practicing neurosurgeon with world-renowned expertise in TBI, and the chair of the Committee on Trauma. RESULTS: After multiple revisions, the position statement was finalized, and approved by the CoSCCC membership in February 2023. Challenges identified include (1) military neurosurgeon attrition, (2) the lack of a doctrinal neurosurgical capabilities requirement during deployed combat operations, and (3) the need for neurosurgical telemedicine capability and in-theater computed tomography scans to triage TBI casualties requiring neurosurgical care. CONCLUSION: Challenges identified regarding neurosurgical capabilities within the deployed trauma system include military neurosurgeon attrition and the lack of a doctrinal requirement for neurosurgical capability during deployed combat operations. To mitigate risk to the force in a future peer-peer conflict, several evidence-based recommendations are made. The solicited civilian commentaries strengthen these recommendations by putting them into the context of civilian TBI management. This neurosurgical capabilities position statement is intended to be a forcing function and a communication tool to inform operational commanders and military medical leaders on the use of these teams on current and future battlefields. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level V.

Metabolic and nutritional support of the enterocutaneous fistula patient: a three-phase approach.

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.

Battlefield pain summit 2022: Expert consensus statements.

BACKGROUND: Battlefield pain occurs in combat casualties who experience multiple severe injuries. The nature of battlefield scenarios requires a distinct approach to battlefield pain research. A battlefield pain summit was thus convened to identify shortcomings in the current understanding of battlefield pain management, review the current state of battlefield pain research, and shape the direction of future research. METHODS: On January 10 to 11, 2022, a hybrid in-person and virtual meeting hosted by the US Army Institute of Surgical Research defined research priorities for the Combat Casualty Care Research Program's Battlefield Pain research portfolio. Summit participants identified the following key focus areas under the umbrella of battlefield pain research: battlefield injury patterns; use of ketamine and nonopioid analgesics; analgesic delivery systems; the impact of analgesia on performance, cognition, and survival; training methods; battlefield regional anesthesia; and research models. Preliminary statements presented during the summit were refined and rank ordered through a Delphi process. RESULTS: Consensus was achieved on 7 statements addressing ideal analgesic properties, delivery systems, operational performance concerns, and pain training. Ketamine was identified as safe and effective for battlefield use, and further research into nonopioid analgesics represented a high priority. CONCLUSION: The 7 consensus statements that emerged from this battlefield pain summit serve as a template to define the near-term research priorities for military-specific battlefield pain research.

Committee on Surgical Combat Casualty Care position statement on the use of single surgeon teams and invited commentaries.

BACKGROUND: Over the last 20 years of war, there has been an operational need for far forward surgical teams near the point of injury. Over time, the medical footprint of these teams has decreased and the utilization of mobile single surgeon teams (SSTs) by the Services has increased. The increased use of SSTs is because of a tactical mobility requirement and not because of proven noninferiority of clinical outcomes. Through an iterative process, the Committee on Surgical Combat Casualty Care (CoSCCC) reviewed the utilization of SSTs and developed an expert-opinion consensus statement addressing the risks of SST utilization and proposed mitigation strategies. METHODS: A small triservice working group of surgeons with deployment experience, to include SST deployments, developed a statement regarding the risks and benefits of SST utilization. The draft statement was reviewed by a working group at the CoSCCC meeting November 2021 and further refined. This was followed by an extensive iterative review process, which was conducted to ensure that the intended messaging was clear to senior medical leaders and operational commanders. The final draft was voted on by the entire CoSCCC membership. To inform the civilian trauma community, commentaries were solicited from civilian trauma leaders to help put this practice into context and to further the discussion in both military and civilian trauma communities. RESULTS: After multiple revisions, the SST statement was finalized in January 2022 and distributed to the CoSCCC membership for a vote. Of 42 voting members, there were three nonconcur votes. The SST statement underwent further revisions to address CoSCCC voting membership comments. Statement commentaries from the President of the American Association for the Surgery for Trauma, the chair of the Committee on Trauma, the Medical Director of the Military Health System Strategic Partnership with the American College of Surgeons and a recently retired military surgeon we included to put this military relevant statement into a civilian context and further delineate the risks and benefits of including the trauma care paradigm in the Department of Defense (DoD) deployed trauma system. CONCLUSION: The use of SSTs has a role in the operational environment; however, operational commanders must understand the tradeoff between tactical mobility and clinical capabilities. As SST tactical mobility increases, the ability of teams to care for multiple casualty incidents or provide sustained clinical operations decreases. The SST position statement is a communication tool to inform operational commanders and military medical leaders on the use of these teams on current and future battlefields.

Quantifying Clinical Opportunities at the Navy Trauma Training Center.

INTRODUCTION: Military-Civilian partnerships (MCPs), such as the Navy Trauma Training Center, are an essential tool for training military trauma care providers. Despite Congressional and military leadership support, sparse data exist to quantify participants' clinical opportunities in MCPs. These preliminary data from an ongoing Navy Trauma Training Center outcomes study quantify clinical experiences and compare skill observation to skill performance. MATERIALS AND METHODS: Participants completed clinical logs after each patient encounter to quantify both patients and procedures they were involved with during clinical rotations; they self-reported demographic data. Data analyses included descriptive statistics and chi-square statistics to compare skills observed to skills performed between the first and second half of the 21-day course. RESULTS: A sample of 47 Navy personnel (30 corpsmen, 10 nurses, 3 physician assistants, 4 physicians) completed 551 clinical logs. Most logs (453/551) reflected experiences in the emergency department, where corpsmen and nurses each spent 102.0 hours, and physician assistants and physicians each spent 105.4 hours. Logs completed per participant ranged from 1 to 31, (mean = 8). No professional group was more likely than others to complete the clinical logs. Completion rates varied by cohort, both overall and by clinical role. Of emergency department logs, 39% reflected highest acuity patients, compared with 21% of intensive care unit logs, and 61% of operating room logs. Penetrating trauma was reported on 16.5% of logs. Primary and secondary trauma assessments were the most commonly reported clinical opportunities, followed by obtaining intravenous access and administration of analgesic medications. With few exceptions, logs reflected skill observation versus skill performance, a ratio that did not change over time. CONCLUSION: Prospective real-time data of actual clinical activity is a crucial measure of the success of MCPs. These preliminary data provide a beginning perspective on how these experiences contribute to maintaining a skilled military medical force.

Preliminary Data on Trauma Knowledge, Confidence, and Stress During Navy Trauma Training.

INTRODUCTION: The Navy Trauma Training Center (NTTC) is a military-civilian partnership that provides advanced trauma training for application across the range of military operations while exposing military medical personnel to high-volume and high-acuity trauma. Few published data evaluate the outcomes of military-civilian partnerships, including NTTC. The purpose of this study is to evaluate the knowledge, confidence, and stress of NTTC participants before, at mid-point, and after completion of the program. Participants include corpsmen (HM), nurses (RNs), physician assistants (PAs), and physicians (MDs). MATERIALS AND METHODS: These are preliminary data from an ongoing prospective, observational study with repeated measures. Included are participants that complete NTTC training. Pre-training measures include a demographic questionnaire, trauma knowledge test, Confidence survey, and the Perceived Stress Scale. These same instruments are completed at mid-training and at the conclusion of the NTTC curriculum. Data were analyzed using paired t-tests and linear mixed models. RESULTS: The sample was composed of 83 participants (49 HM, 18 RNs, 4 PAs, and 12 MDs. Knowledge and confidence increased from baseline to post-NTTC for each clinical role (P < .05). Stress for all roles was low and stable over time (P > .05). CONCLUSIONS: These preliminary data suggest that, as expected, trauma-related knowledge and confidence increase significantly with training at NTTC. Stress was low and stable over time. These data from a small sample of participants indicate NTTC training is increasing participants' trauma knowledge and confidence to care for trauma casualties. Continued collection of data in the ongoing study will allow us to determine whether these early findings persist in the overall study sample and may help inform the optimal length of training needed.

Brief report on combat trauma surgical training using a perfused cadaver model.

BACKGROUND: Surgical combat casualty care presents difficult training challenges. Although several high-fidelity simulation (SIM) techniques have emerged, none are able to fully integrate the many intricacies involved in the care of a complex trauma patient. Herein, we report the use of perfused fresh human cadaver model for training and assessment of forward surgical teams (FSTs). METHODS: Forward surgical teams attend a 4-day combat trauma surgical skills course including focused on trauma exposures. A half-day SIM involves the entire surgical team in four sequential surgical scenarios that involve the neck, chest, abdomen, and extremities, as well as airway management and resuscitation. Teams undergo immediate debriefing and videotape review of team dynamics and technical skills, as well as times to completion of critical interventions. RESULTS: The data evaluated include five initial demonstration courses in which training metrics were available. Each team included both a junior and experienced surgeon, anesthesiologists, and surgical scrub technicians. As FSTs progressed through SIMs, they demonstrated improvements in team dynamics and technical skills evaluations. There was considerable variability in the times to completion of critical intervention, particularly for control of cardiac and vascular injuries. CONCLUSION: Initial evaluations support the use of this novel perfused cadaver model for the training and evaluation of military FSTs. Preliminary data highlight the utility for open vascular, thoracic, and other high-acuity/low-volume procedures critical to combat casualty care. Larger studies are needed for model optimization and further validation of an objective structured technical assessment tool. LEVEL OF EVIDENCE: Care management, level V.

Comparison of 10- versus 14-gauge angiocatheter for treatment of tension pneumothorax and tension-induced pulseless electrical activity with hemorrhagic shock: Bigger is still better.

BACKGROUND: Little is known regarding the effect of hemorrhagic shock on the diagnosis and treatment of tension pneumothorax (tPTX). Recently, the Tactical Combat Casualty Care guidelines included the 10-gauge angiocatheter (10-g AC) as an acceptable alternative to the 14-g AC. This study sought to compare these two devices for decompression of tPTX and rescue from tension-induced pulseless electric activity (tPEA) in the setting of a concomitant 30% estimated blood volume hemorrhage. METHODS: Following a controlled hemorrhage, carbon dioxide was insufflated into the chest to induce either tPTX or tPEA. Tension pneumothorax was defined as a reduction in cardiac output by 50%, and tPEA was defined as a loss of arterial waveform with mean arterial pressure less than 20 mm Hg. The affected hemithorax was decompressed using a randomized 14-g AC or 10-g AC while a persistent air leak was maintained after decompression. Successful rescue from tPTX was defined as 80% recovery of baseline systolic blood pressure, while successful return of spontaneous circulation following tPEA was defined as a mean arterial pressure greater than 20 mm Hg. Primary outcome was success of device. RESULTS: Eighty tPTX and 50 tPEA events were conducted in 38 adult Yorkshire swine. There were no significant differences in the baseline characteristics between animals or devices. In the tPTX model, the 10-g AC successfully rescued 90% of events, while 14-g AC rescued 80% of events (p = 0.350). In the tPEA model, the 10-g AC rescued 87% of events while the 14 AC rescued only 48% of events (p = 0.006). CONCLUSION: The 10-g AC was vastly superior to the 14-g AC for return of spontaneous circulation following tPEA in the setting of 30% hemorrhage. These findings further support the importance of larger caliber devices that facilitate rapid recovery from tPTX, particularly in the setting of polytrauma. LEVEL OF EVIDENCE: Therapeutic, level II.

A Reusable Perfused Human Cadaver Model for Surgical Training: An Initial Proof of Concept Study.

OBJECTIVES: Today's surgical trainees have less exposure to open vascular and trauma procedures. Lightly embalmed cadavers may allow a reusable model that maximizes resources and allows for repeat surgical training over time. METHODS: This was a three-phased study that was conducted over several months. Segments of soft-embalmed cadaver vessels were harvested and perfused with tap water. To test durability, vessels were clamped, then an incision was made and repaired with 5-0 polypropylene. Tolerance to suturing and clamping was graded. In a second phase, both an arterial-synthetic graft and an arterial-venous anastomosis were performed and tested at 90 mmHg perfusion. In the final phase, lower extremity regional perfusion was performed and vascular control of a simulated injury was achieved. RESULTS: Seven arteries and six veins from four cadavers were explanted. All vessels accommodated suture repair over 6 weeks. There was minor leaking at all previous clamp sites. In the anastomotic phase, vessels tolerated grafting, clamping, and perfusion without tearing or leaking. Regional perfusion provided a life-like training scenario. CONCLUSIONS: Explanted vessels of soft-embalmed cadavers show adequate durability over time with realistic vascular surgery handling characteristics. This shows promise as initial proof of concept for a reusable perfused cadaver model. Further study with serial regional and whole-body perfusion is warranted.

Simulation Training for Operational Medicine Providers (STOMP): Impact of a Comprehensive Skills-Based Curriculum for Military General Medical Officers.

INTRODUCTION: A standardized training curriculum designed for general medical officers (GMO) titled Simulation Training for Operational Medicine Providers (STOMP) was recently developed to educate and improve GMOs' procedural skills through directed feedback prior to assuming duties in an operational environment. This study aimed to determine the impact this novel curriculum had on GMOs'confidence levels in 21 core privileges covering eight different subspecialties while stationed at Naval Medical Center Portsmouth (NMCP). MATERIALS AND METHODS: A cohort study from 2015 to 2017 was designed to address our specific aim to examine if the implementation of the STOMP curriculum increased GMOs' confidence levels. Fifty-seven participants enrolled in the study. The GMO case group completed the STOMP curriculum (n = 22), while the control or GMO self-study group (n = 35) did not complete the curriculum. Six months after starting clinical practice at NMCP, both groups completed an online survey that assessed their confidence level in performing each core privilege using a 5-point Likert scale. Scores were analyzed using a Wilcoxon Mann-Whitney test. Research data were derived from an approved Naval Medical Center, Portsmouth, Virginia IRB, protocol number: NMCP.2016.0010. RESULTS: Participants demonstrated a statistically significant increase in self-rated confidence scores (p < 0.05) in nine core privilege skills: punch biopsy, shave biopsy, excisional biopsy, removal of otic foreign body, removal of nasal foreign body, removal of ocular foreign body, tonometry, incision and drainage of a thrombosed hemorrhoid, and reduction of simple closed fractures and dislocations. CONCLUSIONS: These findings suggest that a novel and recently developed standardized simulation training curriculum entitled STOMP improves the confidence levels of early career physicians' in several primary care procedural skills and is an ideal adjunct to traditional lecture-based teaching prior to independent practice in a primary care environment.

The "Top 10" research and development priorities for battlefield surgical care: Results from the Committee on Surgical Combat Casualty Care research gap analysis.

BACKGROUND: The US Military has achieved the highest casualty survival rates in its history. However, there remain multiple areas in combat trauma that present challenges to the delivery of high-quality and effective trauma care. Previous work has identified research priorities for pre-hospital care, but there has been no similar analysis for forward surgical care. METHODS: A list of critical "focus areas" was developed by the Committee on Surgical Combat Casualty Care (CoSCCC). Individual topics were solicited and mapped to appropriate focus areas by group consensus and review of Eastern Association for the Surgery of Trauma (EAST) and Joint Trauma System guidelines. A web-based survey was distributed to the CoSCCC and the military committees of EAST and the American Association for the Surgery of Trauma. Topics were rated on a Likert scale from 1 (low) to 10 (high priority). Descriptives, univariate statistics, and inter-rater correlation analysis was performed. RESULTS: 13 research focus areas were identified (eight clinical and five adjunctive categories). Ninety individual topics were solicited. The survey received 64 responses. The majority of respondents were military (90%) versus civilians (10%). There was moderate to high agreement (inter-rater correlation coefficient = 0.93, p < 0.01) for 10 focus areas. The top five focus areas were Personnel/Staffing (mean, 8.03), Resuscitation and Hemorrhage Management (7.49), Pain/Sedation/Anxiety Management (6.96), Operative Interventions (6.9), and Initial Evaluation (6.9). The "Top 10" research priorities included four in Personnel/Staffing, four in Resuscitation/Hemorrhage Management, and three in Operative Interventions. A complete list of the topics/scores will be presented. CONCLUSIONS: This is the first objective ranking of research priorities for combat trauma care. The "Top 10" priorities were all from three focus areas, supporting prioritization of personnel/staffing of austere teams, resuscitation/hemorrhage control, and damage-control interventions. This data will help guide Department of Defense research programs and new areas for prioritized funding of both military and civilian researchers. LEVEL OF EVIDENCE: Study design, level IV.

Forward Surgical Team Experience (FSTE) Is Associated With Increased Confidence With Combat Surgeon Trauma Skills.

Introduction: Little is known regarding the confidence of military surgeons prior to combat zone deployment. Military surgeons are frequently deployed without peers experienced in combat surgery. We hypothesized that forward surgical team experience (FSTE) increases surgeon confidence with critical skill sets. Methods: We conducted a national survey of military affiliated personnel. We used a novel survey instrument that was piloted and validated by experienced military surgeons to collect demographics, education, practice patterns, and confidence parameters for trauma and surgical critical care skills. Skills were defined as crucial operative techniques for hemorrhage control and resuscitation. Surveyors were blinded to participants, and surveys were returned electronically via REDCap database. Data were analyzed with SPSS using appropriate models. Significance was considered p < 0.05. Results: Of 174 distributed surveys, 86 were completed. Nine individuals failed to characterize their FSTE, thus leaving a sample size of 77. At the time of first deployment, 78.4% were alone or with less experienced surgeons and 53.2% had less than 2 yr of post-residency practice. The respondents' confidence in damage control techniques and seven other trauma skills increased relative to FSTE. After adjusting for years of practice, number of trauma resuscitations performed per month and pre-deployment training, there remained a significant positive association between FSTE and confidence in damage control, thoracic surgery, extremity/junctional hemorrhage control, trauma systems administration, adult critical care and airway management. Conclusions: Training programs and years of general surgery practice do not replace FSTE among military surgeons. Pre-deployment training that mimics FST skill sets should be developed to improve military surgeon confidence and outcomes. Level of Evidence: Prognostic and Epidemiologic, Level IV.
