Introduction: Understanding usage patterns of current paper-based documentation can inform the development of electronic documentation forms for en route care. The primary objective was to analyze the frequency of use of each field within the 3899 L Patient Movement Record documented by en route Critical Care Air Transport Teams. Secondary objectives were to identify rarely utilized form fields and to analyze the proportion of verifiable major events documented within the 3899 L form., Materials and Methods: We performed a retrospective review of 3899 L patient movement records for patients transported via Critical Care Air Transport Teams from January 2019 to December 2019. Scanned 3899 L forms were manually transcribed into a Microsoft Access database for evaluation and analysis. Proportions were calculated for completed fields. Major vital sign event frequency was compared for checkbox fields versus the vital sign flow sheet for each patient. We performed descriptive analyses for the proportion of charts with completed documentation in each evaluated field and the proportion of flow sheet events documented in major event fields., Results: We analyzed 130 records. Fourteen of 18 (77.8%) demographic fields had a 75% or greater completion ratio. Sections with the largest proportion of rarely or never utilized fields (<1.5% completed) were procedures (77.8% of fields) and major events (63.9% of fields). Major event checkboxes had low sensitivity for documented events in the flow sheet: Change in heart rate greater than 20% (1 of 28 patients); increase in the fraction of inspired oxygen requirement of greater than 10% (6 of 23 patients); decrease in mean arterial pressure of greater than 20% (1 in 12 patients); and temperature less than 35.6°C (1 in 13 patients)., Conclusions: Many of the current 3899 L fields are highly utilized, but some 3899 L sections contain high proportions of rarely utilized fields. Major event checkboxes did not consistently capture events documented within the in-flight vital sign flow sheet., (Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2023.

The recent article by Knisely et al. provides a comprehensive review and summary of recent literature describing simulation techniques, training strategies, and technologies to teach medics combat casualty care skills. Some of the results reported by Knisely et al. align with the findings of our team's work, and these findings may be helpful to military leadership with their ongoing efforts to maintain medical readiness. Accordingly, we provide some additional contextual understanding to the results of Knisely et al. in this commentary. Our team recently published two papers describing the results of a large survey that examined Army medic pre-deployment training. Combining the findings of Knisely et al. along with some of the contextual information from our work, we provide some recommendations for improving and optimizing the pre-deployment training paradigm for medics., (© The Association of Military Surgeons of the United States 2023.

The Joint Trauma System (JTS) publishes Clinical Practice Guidelines (CPGs) used by military and civilian healthcare providers worldwide. With the expansion of CPG development in recent years, there was a need to collate, sort, and deconflict existing and new guidance using systematic methodology both within and across CPGs. This need became readily apparent at the start of the COVID-19 pandemic when guidelines were rapidly developed and fielded in deployed environments. To meet the needs of deploying units requesting immediate and concise guidance for managing COVID-19, JTS developed the CPG entitled Management of Covid-19 in Austere Operational Environments. By applying a deconstruction process to organize clinical recommendations across multiple categories, JTS was able to present clear clinical recommendations across "role of care" and "scope of practice." The use of a deconstruction process supported the rapid socialization of the CPG and may have improved clinical understanding among deployed medical teams., (2023.)

Background: Death from uncontrolled hemorrhage occurs rapidly, particularly among combat casualties. The US military has used warm fresh whole blood during combat operations owing to clinical and operational exigencies, but published outcomes data are limited. We compared early mortality between casualties who received warm fresh whole blood versus no warm fresh whole blood., Methods: Casualties injured in Afghanistan from 2008 to 2014 who received ≥2 red blood cell containing units were reviewed using records from the Joint Trauma System Role 2 Database. The primary outcome was 6-hour mortality. Patients who received red blood cells solely from component therapy were categorized as the non-warm fresh whole blood group. Non- warm fresh whole blood patients were frequency-matched to warm fresh whole blood patients on identical strata by injury type, patient affiliation, tourniquet use, prehospital transfusion, and average hourly unit red blood cell transfusion rates, creating clinically unique strata. Multilevel mixed effects logistic regression adjusted for the matching, immortal time bias, and other covariates., Results: The 1,105 study patients (221 warm fresh whole blood, 884 non-warm fresh whole blood) were classified into 29 unique clinical strata. The adjusted odds ratio of 6-hour mortality was 0.27 (95% confidence interval 0.13-0.58) for the warm fresh whole blood versus non-warm fresh whole blood group. The reduction in mortality increased in magnitude (odds ratio = 0.15, P = .024) among the subgroup of 422 patients with complete data allowing adjustment for seven additional covariates. There was a dose-dependent effect of warm fresh whole blood, with patients receiving higher warm fresh whole blood dose (>33% of red blood cell-containing units) having significantly lower mortality versus the non-warm fresh whole blood group., Conclusion: Warm fresh whole blood resuscitation was associated with a significant reduction in 6-hour mortality versus non-warm fresh whole blood in combat casualties, with a dose-dependent effect. These findings support warm fresh whole blood use for hemorrhage control as well as expanded study in military and civilian trauma settings., (Published by Elsevier Inc.)

This Clinical Practice Guideline (CPG) provides a brief summary of the scientific literature for prehospital blood use, with an emphasis on the en route care environment. Updates include the importance of calcium administration to counteract the deleterious effects of hypocalcemia, minimal to no use of crystalloid, and stresses the importance of involved and educated en route care medical directors alongside at a competent prehospital and en route care providers (see Table 1). With the paradigm shift to use FDA-approved cold stored low titer group O whole blood (CS-LTOWB) along with the operational need for continued use of walking blood banks (WBB) and point of injury (POI) transfusion, there must be focused, deliberate training incorporating the different whole blood options. Appropriate supervision of autologous blood transfusion training is important for execution of this task in support of deployed combat operations as well as other operations in which traumatic injuries will occur. Command emphasis on the importance of this effort as well as appropriate logistical support are essential elements of a prehospital blood program as part of a prehospital/en route combat casualty care system., (2021.)

Background: Medics have numerous responsibilities in the combat theater, which include performing lifesaving interventions, providing basic medical and nursing care, and caring for casualties in a variety of scenarios unique to the battlefield. An evaluation of the medic predeployment training paradigm is important and will help to understand its current state and identify areas for improvement. Therefore, the purpose of this study was to perform a focused assessment of Army medic predeployment training to identify patterns that might inform future medic training., Methods: A web-based survey was created using the Intelink.gov platform and sent by e-mail to Army medics who deployed since 2001. Medics were asked to reflect upon the predeployment training from their most recent deployment experience. There were multiple choice, Likert-type scale, and free-text response questions. Descriptive statistics were used to analyze the results., Results: There were 254 respondents who met the study inclusion criteria. Most of the respondents had their clinical competency evaluated (68.5%, n = 174). Respondents reported several acute trauma, basic nursing, and battlefield medicine skills as being critical but also felt that many of these same skills would have benefited from additional predeployment training. Most of the respondents felt very or fully confident and prepared to provide combat casualty care (74.8%, n = 190 and 74.8%, n = 190). There were 64 respondents (25.2%) who reported feeling not at all, slightly, or moderately confident, and 54 (84.4%) of these respondents described in a free-text question wanting additional training before deployment., Conclusion: Respondents reported many skills as being critical to combat casualty care, but several of these skills would have benefited from additional predeployment training. Respondents with more deployment experience or completion of more predeployment training reported feeling more confident and prepared to provide combat casualty care. A common sentiment was the desire for more training of any form before deployment., Level of Evidence: Epidemiological, level IV., (Copyright © 2021 Wolters Kluwer Health, Inc. All rights reserved.)

Introduction: Although military nurses and medics have important roles in caring for combat casualties, no standardized pre-deployment training curriculum exists for those in the Army. A large-scale, survey-based evaluation of pre-deployment training would help to understand its current state and identify areas for improvement. The purpose of this study was to survey Army nurses and medics to describe their pre-deployment training., Materials and Methods: Using the Intelink.gov platform, a web-based survey was sent by e-mail to Army nurses and medics from the active and reserve components who deployed since 2001. The survey consisted of questions asking about pre-deployment training from their most recent deployment experience. Descriptive statistics were used to analyze the results, and free text comments were also captured., Results: There were 682 respondents: 246 (36.1%) nurses and 436 (63.9%) medics. Most of the nurses (n = 132, 53.7%) and medics (n = 298, 68.3%) reported that they were evaluated for clinical competency before deployment. Common courses and topics included Tactical Combat Casualty Care, Advanced Cardiac Life Support, cultural awareness, and trauma care. When asked about the quality of their pre-deployment training, most nurses (n = 186; 75.6%) and medics (n = 359; 82.3%) indicated that their training was adequate or better. Nearly all nurses and medics reported being moderately confident or better (nurses n = 225; 91.5% and medics n = 399; 91.5%) and moderately prepared or better (nurses n = 223; 90.7% and medics n = 404; 92.7%) in their ability to provide combat casualty care. When asked if they participated in a team-based evaluation of clinical competence, many nurses (n = 121, 49.2%) and medics (n = 180, 41.3%) reported not attending a team training program., Conclusions: Most nurse and medic respondents were evaluated for clinical competency before deployment, and they attended a variety of courses that covered many topics. Importantly, most nurses and medics were satisfied with the quality of their training, and they felt confident and prepared to provide care. Although these are encouraging findings, they must be interpreted within the context of self-report, survey-based assessments, and the low response rate. Although these limitations and weaknesses of our study limit the generalizability of our results, this study attempts to address a critical knowledge gap regarding pre-deployment training of military nurses and medics. Our results may be used as a basis for conducting additional studies to gather more information on the state of pre-deployment training for nurses and medics. These studies will hopefully have a higher response rate and better quantify how many individuals received any form of pre-deployment training. Additionally, our recommendations regarding pre-deployment training that we derived from the study results may be helpful to military leadership., (© The Association of Military Surgeons of the United States 2021.

Background: Role 2 forward surgical teams provide damage-control resuscitation and surgery for life- and limb-threatening injuries. These teams have limited resources and personnel, so understanding the anatomic injury patterns seen by these teams is vital for providing adequate training and preparation prior to deployment. The objective of this study was to describe the spectrum of injuries treated at Role 2 facilities in Afghanistan., Methods: Using Department of Defense Trauma Registry data, a retrospective, secondary data analysis was conducted. Eligible patients were all battle or non-battle-injured casualties treated by Role 2 forward surgical teams in Afghanistan from October 2005 to June 2018. Abbreviated Injury Scale (AIS) 2005 codes were used to classify each injury and Injury Severity Score (ISS) was calculated for each patient. Patients with multiple trauma were defined as patients with an AIS severity code >2 in at least two ISS body regions., Results: The data set included 10,383 eligible patients with 45,225 diagnosis entries (range, 1-27 diagnoses per patient). The largest number of injuries occurred in the lower extremity/pelvis/buttocks (23.9%). Most injuries were categorized as minor (39.4%) or moderate (38.8%) in AIS severity, while the largest number of injuries categorized as severe or worse occurred in the head (13.5%). Among head injuries, 1,872 injuries were associated with a cerebral concussion or diffuse axonal injury, including 50.6% of those injuries being associated with a loss of consciousness. There were 1,224 patients with multiple trauma, and the majority had an injury to the extremities/pelvic girdle (58.2%). Additionally, 3.7% of all eligible patients and 10.5% of all patients with multiple trauma did not survive to Role 2 discharge., Conclusion: The injury patterns seen in recent conflicts and demonstrated by this study may assist military medical leaders and planners to optimize forward surgical care in future environments, on a larger scale, and utilizing less resources., Level of Evidence: Epidemiological, Level III.

Introduction: No published study has reported non-surgical interventions performed by forward surgical teams, and there are no current surgical benchmarks for forward surgical teams. The objective of the study was to describe operative procedures and non-operative interventions received by battlefield casualties and determine the operative procedural burden on the trauma system., Methods: This was a retrospective analysis of data from the Joint Trauma System Forward Surgical Team Database using battle and non-battle injured casualties treated in Afghanistan from 2008-2014. Overall procedure frequency, mortality outcome, and survivor morbidity outcome were calculated using operating room procedure codes grouped by the Healthcare Cost and Utilization Project classification. Cumulative attributable burden of procedures was calculated by frequency, mortality, and morbidity. Morbidity and mortality burden were used to rank procedures., Results: The study population was comprised of 10,992 casualties, primarily male (97.8%), with a median age interquartile range of 25.0 (22.0-30.0). Affiliations were non-U.S. military (40.0%), U.S. military (35.1%), and others (25.0%). Injuries were penetrating (65.2%), blunt (32.8), and burns (2.0%). Casualties included 4.4% who died and 14.9% who lived but had notable morbidity findings. After ranking by contribution to trauma system morbidity and mortality burden, the top 10 of 32 procedure groups accounted for 74.4% of operative care, 77.9% of mortality, and 73.1% of unexpected morbidity findings. These procedure groups included laparotomy, vascular procedures, thoracotomy, debridement, lower and upper gastrointestinal procedures, amputation, and therapeutic procedures on muscles and upper and lower extremity bones. Most common non-operative interventions included X-ray, ultrasound, wound care, catheterization, and intubation., Conclusions: Forward surgical team training and performance improvement metrics should focus on optimizing commonly performed operative procedures and non-operative interventions. Operative procedures that were commonly performed, and those associated with higher rates of morbidity and mortality, can set surgical benchmarks and outline training and skillsets needed by forward surgical teams., (© Association of Military Surgeons of the United States 2019.

Managing multicenter clinical trials (MCTs) is demanding and complex. The Randomized controlled Evaluation of high-volume hemofiltration in adult burn patients with Septic shoCk and acUte kidnEy injury (RESCUE) trial was a prospective, MCT involving the impact of high-volume hemofiltration continuous renal replacement therapy on patients experiencing acute kidney injury and septic shock. Ten clinical burn centers from across the United States were recruited to enroll a target sample size of 120 subjects. This manuscripts reviews some of the obstacles and knowledge gained while coordinating the RESCUE trial. The first subject was enrolled in February 2012, 22 months after initial IRB approval and 29 months from the time the grant was awarded. The RESCUE team consisted of personnel at each site, including the lead site, a data coordination center, data safety monitoring board, steering committees, and the sponsor. Seven clinical sites had enrolled 37 subjects when enrollment stopped in February 2016. Obstacles included changes in institutional review boards, multiple layers of review, staffing changes, creation and amendment of study documents and procedures, and finalization of contracts. Successful completion of a MCT requires a highly functional research team with sufficient patient population, expertise, and research infrastructure. Additionally, realistic timelines must be established with strategies to overcome challenges. Inevitable obstacles should be discussed in the pretrial phase and continuous correspondence must be maintained with all relevant research parties throughout all phases of study., (Published by Oxford University Press on behalf of the American Burn Association 2020.)

Introduction: Airway compromise is the second leading cause of potentially survivable death on the battlefield. The purpose of this study was to better understand wartime prehospital airway patients., Materials and Methods: The Role 2 Database (R2D) was retrospectively reviewed for adult patients injured in Afghanistan between February 2008 and September 2014. Of primary interest were prehospital airway interventions and mortality. Prehospital combat mortality index (CMI-PH), hemodynamic interventions, injury mechanism, and demographic data were also included in various statistical analyses., Results: A total of 12,780 trauma patients were recorded in the R2D of whom 890 (7.0%) received prehospital airway intervention. Airway intervention was more common in patients who ultimately died (25.3% vs. 5.6%); however, no statistical association was found in a multivariable logistic regression model (OR 1.28, 95% CI 0.98-1.68). Compared with U.S. military personnel, other military patients were more likely to receive airway intervention after adjusting for CMI-PH (OR 1.33, 95% CI 1.07-1.64)., Conclusions: In the R2D, airway intervention was associated with increased odds of mortality, although this was not statistically significant. Other patients had higher odds of undergoing an airway intervention than U.S. military. Awareness of these findings will facilitate training and equipment for future management of prehospital/prolonged field care airway interventions., (© Association of Military Surgeons of the United States 2020.

While developing a standardized approach to orient new staff in the U.S. Army Institute of Surgical Research Burn Center at Fort Sam Houston in Texas, nurse leaders identified the need to also standardize preceptor selection and instruction. A multidisciplinary research team conducted a two-year pilot project based on the evidence-based Vermont Nurses in Partnership Clinical Transition Framework, which provides a structured method for preceptor selection, development, and evaluation. Minimum preceptor qualifications; preceptor validation processes; and modifiable, unit-specific coaching tools were established. The authors previously published a description of the preceptor program implementation process and their findings. In this article, they discuss lessons learned during the project, highlighting the challenges and obstacles encountered when implementing this preceptorship program.

Introduction: The combat experience during the re-entry stages of Operation Inherent Resolve was distinct from other recent operations, but there is no published literature regarding these "initial entry operations" experiences among forward surgical teams (FSTs) deployed to Role 2 facilities A descriptive analysis of patients treated by FSTs may provide valuable information for Role 2 surgical teams preparing to deploy in support of initial entry operations. The purpose of this analysis was to describe injury mechanism, wounding patterns and interventions performed by a small FST in the re-entry phase in Iraq., Materials and Methods: From July 17, 2015 to January 31, 2016, a split surgical team with two surgeons and an ER physician documented care for all patients treated by their FST located in Iraq. Given their austere environment, FSTs have limited holding capacity, blood supply, and ability to triage and perform advanced procedures. Patients, who arrived to the Role 2 in asystole, were ineligible for the study. The patient population was Iraqi Security Forces as well as Iraqi civilians. No follow-up data were obtained. Using descriptive statistics, we described the basic demographics, health status, blood utilization, injury severity, and injury pattern of the patient population., Results: The final study population included 300 Iraqi casualties. The majority of patients (96%) were discharged alive. Many patients were 16 years or older (96%), male (96%), Iraqi soldiers (86%), and injured during battle (96%). Over one-third of patients (35%) had a form of metabolic acidosis, 7% were hypothermic, and 18% were in shock at admission. The median amount of blood products used was 6 (interquartile ranges (IQR) = 2-12) units, while the median red blood cells:fresh frozen plasma ratio was 1.2:1. Six or more units of blood were given to 67 (22%) patients. The top three diagnoses were laceration (n = 197, 21%), penetrating injury (n = 185, 19%), and fracture (n = 174, 18%). A high number of injuries occurred in the extremities/pelvis and buttocks (n = 360, 38%) and in the abdomen and pelvic contents (n = 145, 15%). Over a quarter of patients (26%) had critical injuries (i.e., military injury severity score ≥25)., Conclusions: Given the Role 2 configuration, these results demonstrate FSTs must be capable of managing critically ill patients with markedly limited resources. This management will include general operations in both adult and pediatric patients, resuscitation with a limited blood supply, and patient assessment with minimal to no diagnostic tools. This analysis can inform resident training, pre-deployment training, as well as sustainment training for surgeons after residency., (© The Author(s) 2019.

Introduction: Critical care is an important component of in-patient and combat casualty care, and it is a major contributor to U.S. healthcare costs. Regular exposure to critically ill and injured patients may directly contribute to wartime skills retention for military caregivers. Data describing critical care services in the Military Health System (MHS), however, is lacking. This study was undertaken to describe MHS critical care services, their resource utilization, and differences in care practices amongst military treatment facilities (MTFs)., Materials and Methods: Twenty-six MTFs representing 38 adult critical care services or intensive care units (ICUs) were surveyed. The survey collected information about organizational structure, resourcing, and unit characteristics at the time of a concurrent 24-h point-prevalence survey designed to describe patient characteristics and staffing in these facilities. The survey was anonymous and protected health information was not collected. We analyzed the data according to high capacity centers (HCCs) (≥200 beds) and low capacity centers (LCCs) (<200 beds). Differences between HCCs and LCCs were compared using Fisher's exact test., Results: Seventeen MTFs (7 HCCs and 10 LCCs), representing 27 ICUs, responded to the survey. This was a 65% response rate for MTFs and a 71% response rate for services/ICUs. HCCs reported more closed vs. open ICUs; more dedicated critical care services (i.e., medical and surgical ICUs vs. mixed ICUs); fewer respiratory therapists available, but more with certification; more total nursing staff and more critical care certified nurses; the use of subjectively more effective protocols (10.5 vs. 6.7 protocols/unit or service); higher utilization of an ICU daily rounds checklist (65% vs. 0%); and less consistency of clinician type participation during multidisciplinary rounds. ICU leadership structure was similar among the institutions. The majority of respondents were unable to provide summary APACHE II scores, but HCCs were more likely to submit this information than LCCs. Most centers perform multidisciplinary rounds daily, but they are more likely to be run by a physician credentialed in critical care at HCCs (85% vs. 59%, p < 0.05). 67% of respondents reported mortality rates <5%. The two services that reported mortality rates greater than 10% were both LCCs., Conclusion: This is the first comprehensive report about MHS critical care services. Despite notable variability in data reporting, an important finding itself, this study highlights notable differences in organizational structure and resourcing between HCCs and LCCs within the MHS. The clinical implication of these differences (i.e., impact on patient outcomes) of these differences require further study. Better understanding of MHS critical care services may improve enterprise decision-making about these services which could ultimately improve care of combat casualties.

Background: Healthcare expenditures are a significant economic cost with critical care services constituting one of its largest components. The Military Health System (MHS) is the largest, global healthcare system of its kind. In this project, we sought to describe critical care services and the patients who receive them in the MHS., Methods: We surveyed 26 military treatment facilities (MTFs) representing 38 critical care services or intensive care units (ICUs). MTFs with multiple ICUs and critical care services responded to the survey as services (e.g., surgical or medical ICU service), whereas MTFs with only one ICU responded as a unit and gave information about all types of patients (i.e., medical and surgical). Our survey was divided into an administrative portion and a 24-h point prevalence survey of patients and patient care. The administrative portion is reported separately in this journal. The 24-h point prevalence survey collected information about all patients present in, admitted to, or discharged from participating services/units during the same 24-h period in December 2014. The survey was anonymous and protected health information was not collected., Findings: Sixteen MTFs (69%) and 27 ICU services/units (71%) returned the point prevalence survey. MTFs with >200 beds (n = 3, 22%) were categorized as "high capacity centers" (HCCs) whereas those with ≤200 beds (n = 13, 78%) were characterized as low capacity centers (LCCs). Two MTFs (one HCC and one LCC) returned only administrative data. The remaining 16 MTFs reported data about 151 patients. In all, 100 (67%) of the patients were at three HCCs during this study period. One HCC accounted for 39% (59 patients) of all patient care during this study. Most patients were cared for in mixed medical/surgical ICUs (34.4%), followed by medical (21.2%), surgical (18.5%), trauma (11.9%), cardiac (7.9%), and burn (6.0%) ICUs. The most common medical indication for admission was cardiac followed by general medical. The most common surgical indications for admission were trauma, other, and cardiothoracic surgery. The average APACHE II score of all patients across both LCCs and HCCs was 11 ± 8.1 (8 ± 7.8 vs. 13 ± 7.7 p = 0.008). The lower acuity of patients in this study is reflected in a high turnover rate, low rate of arterial and central line placements (33%), and low rates of life support (all types, 30%; mechanical ventilation only, 21.2%; noninvasive mechanic ventilation only, 7.9%; and vasoactive medications, 6.6%). Thirty-five (23.2%) patients within the study were affected by a total of 57 complications. The three most common complications experienced were acute kidney injury, bleeding, and sepsis., Discussion: This is the first detailed report about MHS critical care services and the patients receiving care. It describes a low acuity ICU patient population, concentrated at larger MTFs. This study highlights the need for the establishment of a system that allows for the continuous collection of high priority information about clinical care in the MHS in order to facilitate implementation of standardized protocols and process improvements.

Acute kidney injury (AKI) after severe burns is historically associated with a high mortality. Over the past two decades, various modes of renal replacement therapy (RRT) have been used in this population. The purpose of this multicenter study was to evaluate demographic, treatment, and outcomes data among severe burn patients treated with RRT collectively at various burn centers around the United States. After institutional review board approval, a multicenter observational study was conducted. All adult patients aged 18 or older, admitted with severe burns who were placed on RRT for acute indications but not randomized into a concurrently enrolling interventional trial, were included. Across eight participating burn centers, 171 subjects were enrolled during a 4-year period. Complete data were available in 170 subjects with a mean age of 51 ± 17, percent total body surface area burn of 38 ± 26% and injury severity score of 27 ± 21. Eighty percent of subjects were male and 34% were diagnosed with smoke inhalation injury. The preferred mode of therapy was continuous venovenous hemofiltration at a mean delivered dose of 37 ± 19 (ml/kg/hour) and a treatment duration of 13 ± 24 days. Overall, in hospital, mortality was 50%. Among survivors, 21% required RRT on discharge from the hospital while 9% continued to require RRT 6 months after discharge. This is the first multicenter cohort of burn patients who underwent RRT reported to date. Overall mortality is comparable to other critically ill populations who undergo RRT. Most patients who survive to discharge eventually recover renal function.

Management of wartime burn casualties can be very challenging. Burns frequently occur in the setting of other blunt and penetrating injuries. This clinical practice guideline provides a manual for burn injury assessment, resuscitation, wound care, and specific scenarios including chemical and electrical injuries in the deployed or austere setting. The clinical practice guideline also reviews considerations for the definitive care of local national patients, including pediatric patients, who are unable to be evacuated from theater. Medical providers are encouraged to contact the US Army Institute of Surgical Research (USAISR) Burn Center when caring for a burn casualty in the deployed setting.

Background: Timely and optimal care can reduce mortality among critically injured combat casualties. US military Role 2 surgical teams were deployed to forward positions in Afghanistan on behalf of the battlefield trauma system. They received prehospital casualties, provided early damage control resuscitation and surgery, and rapidly transferred casualties to Role 3 hospitals for definitive care. A database was developed to capture Role 2 data., Methods: A retrospective review and descriptive analysis were conducted of battle-injured casualties transported to US Role 2 surgical facilities in Afghanistan from February 2008 to September 2014. Casualties were analyzed by mortality status and location of death (pretransport, intratransport, or posttransport), military affiliation, transport time, injury type and mechanism, combat mortality index-prehospital (CMI-PH), and documented prehospital treatment., Results: Of 9,557 casualties (median age, 25.0 years; male, 97.4%), most (95.1%) survived to transfer from Role 2 facility care. Military affiliation included US coalition forces (37.4%), Afghanistan National Security Forces (23.8%), civilian/other forces (21.3%), Afghanistan National Police (13.5%), and non-US coalition forces (4.0%). Mortality differed by military affiliation (p < 0.001). Among fatalities, most were Afghanistan National Security Forces (30.5%) civilian/other forces (26.0%), or US coalition forces (25.2%). Of those categorized by CMI-PH, 40.0% of critical, 11.2% of severe, 0.8% of moderate, and less than 0.1% of mild casualties died. Most fatalities with CMI-PH were categorized as critical (66.3%) or severe (25.9%), whereas most who lived were mild (56.9%) or moderate (25.4%). Of all fatalities, 14.0% died prehospital (pretransport, 5.8%; intratransport, 8.2%), and 86.0% died at a Role 2 facility (posttransport). Of fatalities with documented transport times (median, 53.0 minutes), most (61.7%) were evacuated within 60 minutes., Conclusions: Role 2 surgical team care has been an important early component of the battlefield trauma system in Afghanistan. Combat casualty care must be documented, collected, and analyzed for outcomes and trends to improve performance., Level of Evidence: Therapeutic/Care Management, level IV.

Objective: The Advanced Burn Life Support (ABLS) program is a burn-education curriculum nearly 30 years in the making, focusing on the unique challenges of the first 24h of care after burn injury. Our team applied high fidelity human patient simulation (HFHPS) to the established ABLS curriculum. Our hypothesis was that HFHPS would be a feasible, easily replicable, and valuable adjunct to the current curriculum that would enhance learner experience., Methods: This prospective, evidenced-based practice project was conducted in a single simulation center employing the American Burn Association's ABLS curriculum using HFHPS. Participants managed 7 separate simulated polytrauma and burn scenarios with resultant clinical complications. After training, participants completed written and practical examinations as well as satisfaction surveys., Results: From 2012 to 2013, 71 students participated in this training. Simulation (ABLS-Sim) participants demonstrated a 2.5% increase in written post-test scores compared to traditional ABLS Provider Course (ABLS Live) (p=0.0016). There was no difference in the practical examination when comparing ABLS-Sim versus ABLS Live. Subjectively, 60 (85%) participants completed surveys. The Educational Practice Questionnaire showed best practices rating of 4.5±0.7; with importance of learning rated at 4.4±0.8. The Simulation Design Scale rating for design was 4.6±0.6 with an importance rating of 4.4±0.8. Overall Satisfaction and Self-Confidence with Learning were 4.4±0.7 and 4.5±0.7, respectfully., Conclusions: Integrating HFHPS with the current ABLS curriculum led to higher written exam scores, high levels of confidence, satisfaction, and active learning, and presented an evidenced-based model for education that is easily employable for other facilities nationwide., (Copyright © 2018 Elsevier Ltd and ISBI.

Objectives: The military uses "just-in-time" training to refresh deploying medical personnel on skills necessary for medical and surgical care in the theater of operations. The burden of pediatric care at Role 2 facilities has yet to be characterized; pediatric predeployment training has been extremely limited and primarily informed by anecdotal experience. The goal of this analysis was to describe pediatric care at Role 2 facilities to enable data-driven development of high-fidelity simulation training and core knowledge concepts specific to the combat zone., Setting and Patients: A retrospective review of the Role 2 Database was conducted on all pediatric patients (< 18 yr) admitted to Role 2 in Afghanistan from 2008-2014., Interventions: Three cohorts were determined based on commercially available simulation models: Group 1: less than 1 year, Group 2: 1-8 years, Group 3: more than 8 years. The groups were sub-stratified by point of injury care, pre-hospital management, and Role 2 facility medical/surgical management., Measurements and Main Results: Appropriate descriptive statistics (chi square and Student t test) were utilized to define demographic and epidemiologic characteristics of this population. Of 15,404 patients in the Role 2 Database, 1,318 pediatric subjects (8.5%) were identified. The majority of patients were male (80.0%) with a mean age of 9.5 years (± SD, 4.5). Injury types included: penetrating (56%), blunt (33%), and burns (7%). Mean transport time from point of injury to Role 2 was 198 minutes (±24.5 min). Mean Glasgow Coma Scale and Revised Trauma Score were 14 (± 0.1) and 7.0 (± 1.4), respectively. Role 2 surgical procedures occurred for 424 patients (32%). Overall mortality was 4% (n = 58)., Conclusions: We have described the epidemiology of pediatric trauma admitted to Role 2 facilities, characterizing the spectrum of pediatric injuries that deploying providers should be equipped to manage. This analysis will function as a needs assessment to facilitate high-fidelity simulation training and the development of "pediatric trauma core knowledge concepts" for deploying providers.

Background: En route care is the transfer of patients requiring combat casualty care within the US military evacuation system. No reports have been published about en route care of patients during transfer from a forward surgical facility (role 2) to a combat support hospital (role 3) for comprehensive care., Objective: To describe patients transferred from a role 2 to a role 3 US military treatment facility in Afghanistan., Methods: A retrospective review of data from the Joint Trauma System Role 2 Database was conducted. Patient characteristics were described by en route care medical attendants., Results: More than one-fourth of patients were intubated at transfer (26.9%), although at transfer fewer than 10% of patients had a base deficit of more than 5 (3.5%), a pH of less than 7.3 (5.2%), an international normalized ratio of more than 2 (0.8%), or temporary abdominal or chest closure (7.4%). The en route care medical attendant was most often a nurse (35.5%), followed by technicians (14.1%) and physicians (10.0%). Most patients (75.3%) were transported by medical evacuation (on rotary-wing aircraft)., Conclusion: This is the first comprehensive review of patients transported from a forward surgical facility to a more robust combat support hospital in Afghanistan. Understanding the epidemiology of these patients will inform provider training and the appropriate skill mix for the transfer of postsurgical patients within a combat setting., (©2018 American Association of Critical-Care Nurses.)

The clinical transition framework (CTF) is a competency-based practice development system used by nursing professional development practitioners to support nurses' initial orientation or transition to a new specialty. The CTF is applicable for both new graduate and proficient nurses. The current framework and tools evolved from 18 years of performance improvement and research projects engaged in both acute and community care environments in urban and rural settings. This article shares core CTF concepts, a description of coaching plans, and a professional accountability statement as experienced within the framework.

Critically injured trauma patients benefit from timely transport and care. Accordingly, the provision of rapid transport and effective treatment capabilities in appropriately close proximity to the point of injury will optimize time and survival. Pre-transport tactical combat casualty care, rapid transport with en route casualty care, and advanced damage control resuscitation and surgery delivered early by small, mobile, forward-positioned Role 2 medical treatment facilities have potential to reduce morbidity and mortality from trauma. This retrospective review and descriptive analysis of trauma patients transported from Role 1 entities to Role 2 facilities in Afghanistan from 2008 to 2014 found casualties to be diverse in affiliation and delivered by various types and modes of transport. Air medical evacuation provided transport for most patients, while the shortest transport time was seen with air casualty evacuation. Although relatively little data were collected for air casualty evacuation, this rapid mode of transport remains an operationally important method of transport on the battlefield. For prehospital care provided before and during transport, continued leadership and training emphasis should be placed on the administration and documentation of tactical combat casualty care as delivered by both medical and non-medical first responders.

Introduction: There is significant nationwide interest in transitioning new and new-to-specialty nurses into practice, especially in burn care. Lack of a structured transition program in our Burn Center was recognized as a contributing factor for nursing dissatisfaction and increased turnover compared to other hospital units. Employee evaluations exposed a need for more didactic instruction, hands-on learning, and preceptor support. The goal of this project was to implement an evidence-based transition to practice program specific to the burn specialty., Material and Methods: The Iowa Model of Evidence-based Practice served as the model for this project. A working group was formed consisting of nurse scientists, clinical nurse leaders, clinical nurse specialists, lead preceptors, staff nurse preceptors and wound care coordinators. A systematic review of the literature was conducted focusing on nurse transition; preceptor development and transitioning nurse training programs with competency assessment, ongoing multifaceted evaluation and retention strategies were created. The evidence-based Vermont Nurses in Partnership (VNIP) Clinical Transition Framework was selected and subsequent education was provided to all Burn Center leaders and staff. Benchmarks for basic knowledge assessment (BKAT) and burn wound care were established among current staff by work site and education level to help evaluate transitioning nurses. Policies were modified to count each preceptor/transitioning nurse dyad as half an employee on the schedule. Multiple high-fidelity simulation scenarios were created to expand hands-on opportunities., Results: From September 2012-December 2013, 110 (57% acute care nursing) Burn Center staff attended the VNIP Clinical Coaching Course, to include 34 interdisciplinary staff (rehabilitation, education, respiratory therapy, and outpatient clinic staff) and 100% of identified preceptors (n=33). A total of 30 new nurses participated in the transition program: 26 (87%) completed, 3 (10%) did not complete, and 1 (3%) received exception (no patient care). Transitioning nurses achieved passing BKAT scores (n=22; 76%) and WC scores (n=24; 93%); individual remediation was provided for those failing to achieve unit benchmarks and transition training was modified to improve areas of weakness. Transitioning nurses' weekly competency progression average initial ratings on a 10 point scale (10 most competent) were 5±2; final ratings averaged 9±1 (n=25) (p<0.0001)., Conclusions: An evidence-based team practice approach toward preceptorship created a standardized, comprehensive and flexible precepting program to assist and support transition to specialty burn practice for experienced nurses. Use of objective metrics enabled ongoing assessment and made training adaptable, individualized, and cost effective. Application of this standardized approach across our organization may improve consistency for all transitions in practice specialty., (Copyright © 2017. Published by Elsevier Ltd.)

Introduction: In 2006, burn clinical practice guidelines were developed to provide recommendations for optimal care of U.S. military and local national burn casualties. As part of that effort, a paper-based Burn Flow Sheet (BFS) was included to document the burn resuscitation of combat casualties with ≥20% total body surface area burns. The purpose of this study was to evaluate the BFS in terms of ongoing utilization, resuscitation management, and outcomes of patients transported., Materials and Methods: A retrospective review was performed of hard-copy BFSs received from January 2007 to December 2013. En route injury and treatment data from these flowsheets were manually transcribed into the research database. Outcomes and complications of BFS subjects were extracted from the Burn Center Registry and added to the research database., Results: A total of 73 BFSs were collected from the study period. On average, BFSs were 61 ± 30% complete with a total of 14.7 ± 7 hours documented per patient in the first 24-hours postburn. Patients received nearly 7 L more fluid than estimated by traditional formulas. Sixteen patients (26%) received greater than 250 mL/kg of fluid, half of whom had concomitant traumatic injuries. Fifteen patients received a fasciotomy (21%), 4 received a laparotomy (5%), and 8 (11%) received both. No patients developed abdominal compartment syndrome associated with fluid resuscitation. Overall mortality was 21%., Conclusions: Although the majority of providers did initiate a BFS, it was not always used as intended; problems included missing data and miscalculations. Although there was a clear improvement with decline in the incidence of abdominal compartment syndrome, mortality did not change for severely burned patients. Simplification of the recommendations, additional built-in prompts, and automated tools such as computerized decision support software may help standardize practice and improve outcomes., (Reprint & Copyright © 2017 Association of Military Surgeons of the U.S.)

A nurse residency program can support transition for new-to-specialty nurses but requires commitment of time and resources. This implementation project used a specialty residency program shown to be effective in a Burn Center, and translated it into the Emergency Department and Maternal Child Health area located within the same medical treatment facility. Preceptor survey responses and leadership assessment of program suitability provided data related to intervention impact. The evidence pertaining to developing specialty knowledge, skills, competency, and clinical reasoning validated program efficacy. Project outcomes justify investment in building a standardized transitional support system.

For many acute care nursing units, such as the Burn Progressive Care Unit (BPCU) at the U.S. Army Burn center, staff stress and burnout is always a concern for leaders. Job stress not only contributes to nursing turnover, but can have a negative impact on patient care. The purpose of this project was to develop a training platform for nursing staff education and teambuilding with the intent of improving nurse satisfaction, increasing resiliency, building unit cohesion, enhancing morale, and increasing staff awareness of unit performance. All nursing staff were given an 8-hour training day, half of which was focused on education and the other half on teambuilding and resiliency. At the end of the staff development day (SDD), participants were encouraged to complete an evaluation; all activities were scored on a 10-point scale, with 10 representing the most informative. In total, 46 of 48 staff (96%) participated in the first two SDDs. During the first iteration (Spring 2015), participants scored all activities very high, with a total average score of 9.15 ± 0.26 (n = 246). In the Fall of 2015, the SDD program was again rated well, with an average score of 9.36 ± 0.13 (n = 276). The SDD program has been successful in supporting teamwork and resiliency among BPCU staff. Staff feedback supported success in meeting the objectives of building unit cohesion and increasing satisfaction and morale.

Background: A Role 2 registry (R2R) was developed in 2008 by the US Joint Trauma System (JTS). The purpose of this project was to undertake a preliminary review of the R2R to understand combat trauma epidemiology and related interventions at these facilities to guide training and optimal use of forward surgical capability in the future., Methods: A retrospective review of available JTS R2R records; the registry is a convenience sample entered voluntarily by members of the R2 units. Patients were classified according to basic demographics, affiliation, region where treatment was provided, mechanism of injury, type of injury, time and method of transport from point of injury (POI) to R2 facility, interventions at R2, and survival. Analysis included trauma patients aged ≥18 years or older wounded in year 2008 to 2014, and treated in Afghanistan., Results: A total of 15,404 patients wounded and treated in R2 were included in the R2R from February 2008 to September 2014; 12,849 patients met inclusion criteria. The predominant patient affiliations included US Forces, 4,676 (36.4%); Afghan Forces, 4,549 (35.4%); and Afghan civilians, 2,178 (17.0%). Overall, battle injuries predominated (9,792 [76.2%]). Type of injury included penetrating, 7,665 (59.7%); blunt, 4,026 (31.3%); and other, 633 (4.9%). Primary mechanism of injury included explosion, 5,320 (41.4%); gunshot wounds, 3,082 (24.0%); and crash, 1,209 (9.4%). Of 12,849 patients who arrived at R2, 167 (1.3%) were dead; of 12,682 patients who were alive upon arrival, 342 (2.7%) died at R2., Conclusion: This evaluation of the R2R describes the patient profiles of and common injuries treated in a sample of R2 facilities in Afghanistan. Ongoing and detailed analysis of R2R information may provide evidence-based guidance to military planners and medical leaders to best prepare teams and allocate R2 resources in future operations. Given the limitations of the data set, conclusions must be interpreted in context of other available data and analyses, not in isolation., Level of Evidence: Epidemiologic study, level IV.

Background: As new conflicts emerge and enemies evolve, military medical organizations worldwide must adopt the "lessons learned." In this study, we describe roles of care (ROCs) deployed and injuries sustained by both US and Israeli militaries during recent conflicts. The purpose of this collaborative work is facilitate exchange of medical data among allied forces in order to advance military medicine and facilitate strategic readiness for future military engagements that may involve less predictable situations of evacuation and care, such as prolonged field care., Methods: This retrospective study was conducted for the periods of 2003 to 2014 from data retrieved from the Department of Defense Trauma Registry and the Israel Defense Force (IDF) Trauma Registry. Comparative analyses included ROC capabilities, casualties who died of wounds, as well as mechanism of injury, anatomical wound distribution, and Injury Severity Score of US and IDF casualties during recent conflicts., Results: Although concept of ROCs was similar among militaries, the IDF supports increased capabilities at point of injury and Role 1 including the presence of physicians, but with limited deployment of other ROCs; conversely, the US maintains fewer capabilities at Role 1 but utilized the entire spectrum of care, including extensive deployment of Roles 2/2+, during recent conflicts. Casualties from US forces (n = 19,005) and IDF (n = 2,637) exhibited significant differences in patterns of injury with higher proportions of casualties who died of wounds in the US forces (4%) compared with the IDF (0.6%)., Conclusions: As these data suggest deployed ROCs and injury patterns of US and Israeli militaries were both conflict and system specific. We envision that identification of discordant factors and common medical strategies of the two militaries will enable strategic readiness for future conflicts as well as foster further collaboration among allied forces with the overarching universal goal of eliminating preventable death on the battlefield.

The purpose of this study was to identify the presence or absence of pathogenic bacteria on burn intensive care unit employees' common access cards (CACs) and identity badges (IDs) and to identify possible variables that may increase risk for the presence of those bacteria. A prospective, cross-sectional study was conducted in our regional Burn Center in which bacterial swab specimens were collected from both the CAC and ID of 10 burn intensive care unit employees in each of five cohorts (nurses, respiratory therapists, physical therapists, physicians, and ancillary staff). Ten additional paired samples, collected from direct care staff in the outpatient burn clinic, served as control. Additional information described how the cards were worn and if/how they had been cleaned in the previous week. Fifty-eight CACs and 60 IDs were swabbed from participants. The overall contamination rate was 75%, with no trends identified based on how cards were worn. Bacteria were recovered from 86% (50/58) of CACs and 65% (39/60) of IDs, with CACs being significantly more contaminated overall than IDs (P < .01). In terms of potentially pathogenic bacteria, the overall rate was 3%, with 100% of those isolates coming from the outpatient clinic staff cohort (P < .001). When cleaned in the last week (n = 16), the contamination rate dropped to 50% overall (P = .003), indicating that even periodic cleaning appears to have a positive effect on bacterial contamination rates. The simple practice of routine identity card decontamination may reduce potential threats to patient safety as a result of nosocomial bacterial transmission.

Background: The Military Injury Severity Score (mISS) was developed to better predict mortality in complex combat injuries but has yet to be validated., Methods: US combat trauma data from Afghanistan and Iraq from January 1, 2003, to December 31, 2014, from the US Department of Defense Trauma Registry (DoDTR) were analyzed. Military ISS, a variation of the ISS, was calculated and compared with standard ISS scores.Receiver operating characteristic curve, area under the curve, and Hosmer-Lemeshow statistics were used to discriminate and calibrate between mISS and ISS. Wilcoxon-Mann-Whitney, t test and χ tests were used, and sensitivity and specificity calculated. Logistic regression was used to calculate the likelihood of mortality associated with levels of mISS and ISS overall., Results: Thirty thousand three hundred sixty-four patients were analyzed. Most were male (96.8%). Median age was 24 years (interquartile range [IQR], 21-29 years). Battle injuries comprised 65.3%. Penetrating (39.5%) and blunt (54.2%) injury types and explosion (51%) and gunshot wound (15%) mechanisms predominated. Overall mortality was 6.0%.Median mISS and ISS were similar in survivors (5 [IQR, 2-10] vs. 5 [IQR, 2-10]) but different in nonsurvivors, 30 (IQR, 16-75) versus 24 (IQR, 9-23), respectively (p < 0.0001). Military ISS and ISS were discordant in 17.6% (n = 5,352), accounting for 56.2% (n = 1,016) of deaths. Among cases with discordant severity scores, the median difference between mISS and ISS was 9 (IQR, 7-16); range, 1 to 59. Military ISS and ISS shared 78% variability (R = 0.78).Area under the curve was higher in mISS than in ISS overall (0.82 vs. 0.79), for battle injury (0.79 vs. 0.76), non-battle injury (0.87 vs. 0.86), penetrating (0.81 vs. 0.77), blunt (0.77 vs. 0.75), explosion (0.81 vs. 0.78), and gunshot (0.79 vs. 0.73), all p < 0.0001. Higher mISS and ISS were associated with higher mortality. Compared with ISS, mISS had higher sensitivity (81.2 vs. 63.9) and slightly lower specificity (80.2 vs. 85.7)., Conclusion: Military ISS predicts combat mortality better than does ISS., Level of Evidence: Prognostic and epidemiologic study, level III.

Skin grafts intended for autologous transplant may be dropped on the operating room floor during handling. The authors examined optimal procedures for decontaminating tissue intended for burn surgery. Porcine skin (5 × 5 cm sections) harvested from expired animals using standard procedures was inoculated with either 10(6) CFU/ml Staphylococcus aureus or Klebsiella pneumoniae. Decontaminating strategies were compared: 10% povidone iodine, 0.04% chlorhexidine, or 50 U/ml bacitracin for injection, and mechanical agitation using normal saline or sterile water; each agent was applied for 60 seconds. Each skin section was blended and plated on agar for bacterial enumeration using the spread plate method. Tissue viability was evaluated in parallel using a cell viability reagent, along with a control (heat at 200 °C for 5 min). Bacterial counts were log transformed; one-way ANOVA with Tukey-Kramer HSD analysis were performed. Concentration of organisms <10(5) CFU/g was considered clinically insignificant colonization. Eight donors provided 21 S. aureus and six K. pneumoniae samples. After exposure, mean organism concentration (CFU/g) was <10(5) for povidone iodine (S. aureus 2.83 × 10(4); K. pneumoniae 1.85 × 10(4)), chlorhexidine (S. aureus 4.52 × 10(4); K. pneumoniae 1.77 × 10(4)), and normal saline (K. pneumoniae 8.76 × 10(4)) treated groups. After log transform, only povidone iodine and chlorhexidine were found to be different from control in both groups. Viability was decreased in the positive control group, but not in treatment groups. Agents routinely used for surgical skin prep (povidone iodine and chlorhexidine), reduced both Gram-positive and Gram-negative contamination in tissue intended for skin grafting procedures. Antiseptic treatments did not impair the cellular viability of porcine skin.

Since 2009, out-of-hospital care of junctional hemorrhage bleeding from the trunk-appendage junctions has changed, in part, due to the newly available junctional tourniquets (JTs) that have been cleared by the US Food and Drug Administration. Given four new models of JT available in 2014, several military services have begun to acquire, train, or even use such JTs in care. The ability of users to be trained in JT use has been observed by multiple instructors. The experience of such instructors has been broad as a group, but their experience as individuals has been neither long nor deep. A gathering into one source of the collective experience of trainers of JT users could permit a collation of useful information to include lessons learned, tips in skill performance, identification of pitfalls of use to avoid, and strategies to optimize user learning. The purpose of the present review is to record the experiences of several medical personnel in their JT training of users to provide a guide for future trainers., (2015.)

Severe weight loss resulting from inadequate nutritional intake along with the hypermetabolism after thermal injury can result in impaired immune function and delayed wound healing. This observational study was conducted on adults admitted between October 2007 and April 2012 with at least 20% total body surface area burn requiring excision who previously tolerated gastric enteral nutrition at calorie goal and who returned from surgery hemodynamically stable (no new pressor requirement) and compared the effect of goal rate re-initiation versus slow re-initiation after the first excision and grafting. Demographic, intake, and tolerance data were collected during the 36h following surgery and were analyzed with descriptive and comparative statistics. Data were collected on 14 subjects who met the inclusion criteria. Subjects in the goal rate re-initiation group (n=7) met a significantly greater percentage of caloric goals (99±12% versus 58±21%, p=0.003) during the 36h following surgery than subjects in the slow re-initiation group (n=7). There were no incidences of emesis, aspiration, or ischemic bowel in either group. The goal rate re-initiation group had a 29% incidence of either stool output >1L (n=1) or gastric residual volumes >500mL (n=1), whereas these were not present in the slow re-initiation group (p=0.462). In conclusion, in this small pilot study, we found that enteral nutrition could be re-initiated after the first excision and grafting in those patients who previously tolerated gastric enteral nutrition meeting caloric goals who return from surgery hemodynamically stable without a significant difference in intolerance and with a significantly higher percentage of calorie goals achieved, but larger studies are required., (Published by Elsevier Ltd.)

The administration of blood products to battlefield casualties in the prehospital arena has contributed significantly to the survival of critically injured patients in Afghanistan over the past 5 years. Given as part of an established military "chain of survival," blood product administration has represented a step-change improvement in capability for both UK and US tactical aeromedical evacuation (TACEVAC) platforms. The authors explore current concepts, analyzing and exploring themes associated with early use of blood products (fresh frozen plasma [FFP] and red blood cells [RBCs]), and they compare and evaluate a US/UK study analyzing the differences and recommending future strategy. The subject matter expert (SME) consensus guidelines developed for use by the US Army Air Ambulance units commonly known as call sign "DUSTOFF." These TACEVAC assets in Afghanistan were validated in this retrospective study. Using statistical analysis, the authors were able to ascertain that the current DUSTOFF SME-derived guidelines offer a sensitivity of 63.04% and a specificity of 89.07%. By adjusting the indicators to include a single above-ankle amputation with a systolic blood pressure (SBP) less than 90 mmHg and pulse greater than 120/min, the sensitivity could be increased to 67.39% while maintaining the specificity at 89.07%. In our data set, a single amputation above the ankle, in combination with an SBP of less than 100 mmHg and a pulse of greater than 120/min, increased the sensitivity to 76% but with a slight drop in specificity to 86%. Further study of military prehospital casualty data is under way to identify additional physiological parameters that will allow simple scoring tools in the remote setting to guide the administration of prehospital blood products., (2014.)

As the only burn center in the Department of Defense, the U.S. Army Institute of Surgical Research is the primary location for care of service members with burn injuries. The combat operations in Iraq and Afghanistan during the past decade have caused an increase in burn patients. As a result of this increased need, advancements in care were developed. The speed and precision of transporting patients from the battlefield to the burn center has improved over previous conflicts. Technological advancements to support treating complications of burn wound healing were leveraged and are now integrated into daily practice. Clinical decision support systems were developed and deployed at the burn center as well as to combat support hospitals in combat zones. Technology advancements in rehabilitation have allowed more service members to return to active duty or live productive civilian lives. All of these advancements were developed in a patient-centered, interdisciplinary environment where the nurses are integrated throughout the research process and clinical practice with the end goal of healing combat burns in mind.

The Combat Ready Clamp (CRoC™) was designed to control hemorrhage from the groin region, on the battlefield. The purpose of this experiment was to determine whether CRoC™ user performance varied by the surface the casualty laid on (flat-hard, flat-soft, and curved-soft) and how quickly the device could be applied. The commercial manikin selected to assess user performance was designed to train soldiers in CRoC™ use. The manikin simulated severe hemorrhage from an inguinal wound, controllable by correct use of the CRoC™. Each individual (n = 6) performed 3 iterations on each of the 3 surfaces (54 iterations total). The CRoC™ achieved hemorrhage control 100% of the time (54/54). Patient surface affected time to stop bleeding. The flat-soft surface (padded, 55 ± 9.7 seconds) was significantly different from the curved-soft surface (litter, 65 ± 16.5 seconds) and had the lowest overall total time (p = 0.007); time for the hard-flat surface was 58 ± 9.5 seconds. Users were trained to use the Combat Ready Clamp effectively, and the surface the casualty was lying on made some difference to user performance. All six persons trained had success in all nine of their iterations of CRoC™ use- a 100% rate. These findings indicate that training was effective and that training of other users is plausible, feasible, and practical within the scope of the present evidence.
