Optimizing prophylaxis against venous thromboembolic events (VTEs) is a critical issue in the care of injured patients. Although these patients are at significant risk of developing VTE, they also ...present competing concerns related to exacerbation of bleeding from existing injuries. Especially after high-risk trauma, including injuries to the abdominal solid organs, brain, and spine, trauma providers must delineate the time period in which VTE prophylaxis successfully reduces VTE rates without encouraging bleeding. Although existing data are primarily retrospective in nature and further study is required, literature supports early VTE chemoprophylaxis initiation even for severely injured patients. Early initiation is most frequently defined as <48 hours from admission but varies from <24 hours to 72 hours and occasionally refers to time from initial trauma. Prior to chemical VTE prophylaxis initiation in patients at risk for bleeding, an observation period is necessary during which injuries must show themselves to be hemostatic, either clinically or radiographically. In the future, prospective examination of optimal timing of VTE prophylaxis is necessary. Further study of specific subsets of trauma patients will allow for development of effective VTE mitigation strategies based upon collective risks of VTE and hemorrhage progression.
Venous thromboembolism (VTE) is a significant cause of morbidity and mortality during recovery from injury and can result in significant healthcare costs. Despite advances in the past several decades ...in our approach to VTE prophylaxis after injury, opportunities exist to improve the delivery and implementation of optimal VTE prophylaxis. Here, we aim to identify consensus research questions related to VTE across all NTRAP Delphi expert panels to further guide the research agenda aimed at preventing VTE after injury.
This is a secondary analysis of consensus-based research priorities that were collected using a Delphi methodology by 11 unique NTRAP panels that were charged with unique topic areas across the spectrum of injury care. The database of questions was queried for the keywords "VTE", "venous thromboembo", and "DVT", then grouped into relevant topic areas.
There were 86 VTE-related research questions identified across 9 NTRAP panels. 85 questions reached consensus with 24 rated high priority, 60 medium priority and 1 low priority. Questions related to the timing of VTE prophylaxis (n = 17) were most common, followed by questions related to risk factors for the development of VTE (n = 16), the effects of tranexamic acid on VTE (n = 11), the approach to dosing of pharmacologic prophylaxis (n = 8), as well as the pharmacologic prophylactic medication choice for optimal VTE prophylaxis (n = 6).
NTRAP panelists identified 85 consensus-based research questions that should drive dedicated extramural research funding opportunities to support quality studies aimed at optimizing VTE prophylaxis after injury.

The 2016 National Academies of Science, Engineering and Medicine call for a national integrated, military-civilian trauma action plan to achieve zero preventable deaths and disability after injury ...included a proposal to establish a National Trauma Research Action Plan to "strengthen trauma research and ensure that the resources available for this research are commensurate with the importance of injury and the potential for improvement in patient outcomes." The Department of Defense funded the Coalition for National Trauma Research to generate a comprehensive research agenda spanning the continuum of trauma/burn care from prehospital to rehabilitation. The Burn/Reconstructive Surgery group represents one focus area for this research agenda development.
Experts in burn and reconstructive surgery research identified gaps in knowledge, generated research questions and prioritized questions using a consensus driven Delphi survey approach. Participants were identified using established Delphi recruitment guidelines to ensure heterogeneity and generalizability with military and civilian representatives. Literature reviews informed the panel. Panelists were encouraged to use a PICO format to generate research questions: Patient/Population; Intervention; Compare/Control; Outcome. Participants ranked the priority of each question on a nine-point Likert scale, which was categorized to represent low, medium, and high priority items. Consensus was defined based on ≥60% panelist agreement.
Subject matter experts generated 949 research questions in 29 Burn & 26 Reconstruction topics. Five hundred ninety-seven questions reached consensus. Of these, 338 (57%) were high-priority, 180 (30%), medium-priority, and 78 (13%) low-priority questions.
Many high-priority questions translate to complex wound management and outcomes. Panel recognition that significant gaps in knowledge exist in understanding functional outcomes after injury underscores the importance of long-term recovery metrics even when studying acute injury or interventions such as resuscitation or inhalation injury. Funding agencies and burn/reconstructive surgery researchers should consider these gaps when they prioritize future research.
Expert consensus, Level IV.
On May 4 and 5, 2022, a meeting of multidisciplinary stakeholders in the prevention and treatment of venous thromboembolism (VTE) after trauma was convened by the Coalition for National Trauma ...Research, funded by the National Heart, Lung, and Blood Institute of the National Institutes of Health, and hosted by the American College of Surgeons in Chicago, Illinois. This consensus conference gathered more than 40 in-person and 80 virtual attendees, including trauma surgeons, other physicians, thrombosis experts, nurses, pharmacists, researchers, and patient advocates. The objectives of the meeting were twofold: (1) to review and summarize the present state of the scientific evidence regarding VTE prevention strategies in injured patients and (2) to develop consensus on future priorities in VTE prevention implementation and research gaps.To achieve these objectives, the first part of the conference consisted of talks from physician leaders, researchers, clinical champions, and patient advocates to summarize the current state of knowledge of VTE pathogenesis and prevention in patients with major injury. Video recordings of all talks and accompanying slides are freely available on the conference website ( https://www.nattrauma.org/research/research-policies-templates-guidelines/vte-conference/ ). Following this curriculum, the second part of the conference consisted of a series of small-group breakout sessions on topics potentially requiring future study. Through this process, research priorities were identified, and plans of action to develop and undertake future studies were defined.The 2022 Consensus Conference to Implement Optimal VTE Prophylaxis in Trauma answered the National Trauma Research Action Plan call to define a course for future research into preventing thromboembolism after trauma. A multidisciplinary group of clinical champions, physicians, scientists, and patients delineated clear objectives for future investigation to address important, persistent key knowledge gaps. The series of papers from the conference outlines the consensus based on the current literature and a roadmap for research to answer these unanswered questions.
Objective
Failure to recognize symptoms of non‐human papillomavirus‐associated oropharyngeal squamous cell carcinoma (HPV(−)OPSCC) at presentation can delay diagnosis and treatment. We aim to ...identify patient factors and provider practice patterns that delay presentation and care in HPV(−)OPSCC.
Methods
Retrospective review at a tertiary care center. Patients with HPV(−)OPSCC receiving treatment from 2006 to 2016. Patients were excluded if their date of symptom onset or diagnosis was unknown after thorough review of the electronic medical record or their tissue was not tested for HPV or p16. Clinical data, workup, and care timelines were ed. Univariate and multivariable linear regressions were performed to determine associations between patient and provider factors and delays in care.
Results
Of 70 included patients, 52 (74%) were male and mean age was 60.5 (SD = 9.0). Median time to diagnosis was 69 days (IQR = 32–127 days), with a median latency of 30 days (IQR = 12–61 days) from symptom onset to first presentation and 19.5 days (IQR = 4–46 days) from the first presentation to diagnosis. Most patients visited at least 2 providers (n = 52, 74%) before diagnosis. Evaluation by 3 or more providers prior to diagnosis was associated with significant delays in diagnosis of nearly a year (357.7 days, p < 0.001) and being treated or prescribed analgesia prior to diagnosis was significantly associated with delays in diagnosis (p = 0.004) on univariate regression analysis.
Conclusions
Delays in care related to evaluations by multiple providers and misdiagnosis prolonged time to diagnosis in HPV(−)OPSCC. Improved patient and provider education is necessary to expedite the diagnosis of HPV(−)OPSCC.

In 2016, the National Academies of Sciences, Engineering, and Medicine issued a report calling for a National Trauma Research Action Plan (NTRAP) requiring a resourced, coordinated, joint approach to ...trauma care research. The National Academies of Sciences, Engineering, and Medicine report recommended the identification of regulatory barriers to trauma research. The NTRAP Regulatory Challenges Panel of trauma researchers and regulatory professionals was convened to identify the most challenging aspects of regulatory processes involved in conducting research.
Trauma researchers and regulatory experts were recruited to identify and rate challenging regulatory issues in 2021 to 2022. Challenge statements were developed from a comprehensive scoping review. Panelists rated the challenge level for each statement on a 9-point Likert scale. The Delphi survey was conducted over three online rounds. Consensus was defined a priori as ≥60% agreement. Results of the Delphi survey were presented to the panel during a webinar. Panel participants then participated in breakout sessions to strategize solutions, share lessons learned, and identify where more regulatory guidance is needed.
Thirty-eight subject matter experts rated 175 regulatory challenges, of which 141 (81%) reached the consensus threshold. Of the consensus-reaching challenge statements, 42 had a challenge rating of 6 or higher. Among the highest-rated challenges were issues pertaining to conducting prehospital research, exception from informed consent, mistrust of research among various racial and ethnic groups, and issues specific to conducting pediatric trauma research.
This Delphi survey rated challenges culled from a regulatory literature scoping review. The panel identified the most challenging aspects of human subjects protection while conducting trauma research and recommended strategies and best practices to address them. The findings from this study were used to develop the NTRAP Investigator Toolkit, which is available on the internet as a resource for trauma researchers.

To describe the current literature regarding long-term physical, mental, and social outcomes of firearm injury survivors in the United States.
We systematically searched the PubMed/MEDLINE and Embase ...databases for articles published from 2013 to 2019 that involved survivors of acute physical traumatic injury aged 18 or older and reported health outcomes between 6 months and 10 years postinjury. Out of 747 articles identified, seven reported outcomes on United States-based civilian patients whose mechanism of injury involved firearms. We extended our publication date criteria from 1995 to 2020 and expanded the search strategy to include medical subject headings terms specific for firearm injury outcomes. Ultimately, ten articles met inclusion criteria.
When studied, a significant proportion of patients surviving firearm injury screened positive for posttraumatic stress disorder (49%-60%) or were readmitted (13%-26%) within 6 months postinjury. Most studies reported worse long-term outcomes for firearm injury survivors when compared both to similarly injured motor vehicle collision survivors and to the United States general population, including increased chronic pain, new functional limitations, and reduced physical health composite scores. Studies also reported high rates of posttraumatic stress disorder, reduced mental health composite scores, lower employment and return to work rates, poor social functioning, increased alcohol, and substance abuse.
Research on the long-term health impact of firearm injury is scant, and heterogeneity in available studies limits the ability to fully characterize the outcomes among these patients. A better understanding of the long-term health impact of firearm injury would support systematic change in policy and patient care to improve outcomes.
Venous thromboembolism (VTE) is a major issue in trauma patients. Without prophylaxis, the rate of deep venous thrombosis approaches 60% and even with chemoprophylaxis may be nearly 30%. Advances in ...VTE reduction are imperative to reduce the burden of this issue in the trauma population. Novel approaches in VTE prevention may include new medications, dosing regimens, and extending prophylaxis to the postdischarge phase of care. Standard dosing regimens of low-molecular-weight heparin are insufficient in trauma, shifting our focus toward alternative dosing strategies to improve prophylaxis. Mixed data suggest that anti-Xa-guided dosage, weight-based dosing, and thromboelastography are among these potential strategies. The concern for VTE in trauma does not end upon discharge, however. The risk for VTE in this population extends well beyond hospitalization. Variable extended thromboprophylaxis regimens using aspirin, low-molecular-weight heparin, and direct oral anticoagulants have been suggested to mitigate this prolonged VTE risk, but the ideal approach for outpatient VTE prevention is still unclear. As part of the 2022 Consensus Conference to Implement Optimal Venous Thromboembolism Prophylaxis in Trauma, a multidisciplinary array of participants, including physicians from multiple specialties, pharmacists, nurses, advanced practice providers, and patients met to attack these issues. This paper aims to review the current literature on novel approaches for optimizing VTE prevention in injured patients and identify research gaps that should be investigated to improve VTE rates in trauma.
Until recently, survival has been the main outcome measure for injury research. Given the impact of injury on quality of life, the National Academies of Science, Engineering, and Medicine has called ...for advancing the science of research evaluating the long-term outcomes of trauma survivors. This is necessary so that treatments and interventions can be assessed for their impact on a trauma patients' long-term functional and psychosocial outcomes. We sought to propose a set of core domains and measurement instruments that are best suited to evaluate long-term outcomes after traumatic injury with a goal for these measures to be adopted as a national standard.
As part of the development of a National Trauma Research Action Plan, we conducted a two-stage, five-round modified online Delphi consensus process with a diverse panel of 50 key stakeholders including clinicians, researchers, and trauma survivors from more than 9 professional areas across the United States. Before voting, panelists reviewed the results of a scoping review on patient-reported outcomes after injury and standardized information on measurement instruments following the Consensus-based Standards for the Selection of Health Measurement Instruments guidelines.
The panel considered a preliminary list of 74 outcome domains (patient-reported outcomes) and ultimately reached the a priori consensus criteria for 29 core domains that encompass aspects of physical, mental, social, and cognitive health. Among these 29 core domains, the panel considered a preliminary list of 199 patient-reported outcome measures and reached the a priori consensus criteria for 14 measures across 13 core domains. Participation of panelists ranged from 65% to 98% across the five Delphi rounds.
We developed a core outcome measurement set that will facilitate the synthesis, comparison, and interpretation of long-term trauma outcomes research. These measures should be prioritized in all future studies in which researchers elect to evaluate long-term outcomes of traumatic injury survivors.
