Improving trauma systems in various forms has always been an important aspect of health policy. While several papers have reported the implementation of a structured trauma system of care, research evidence on the effectiveness of such regionalization for improvement in trauma outcome is limited. Systematic review. Medline, EMbase, EconLit and Health Management Information Consortium were searched, using sensitive search terms, for interventional studies that reported a trauma regionalization system as their intervention, and compared important outcomes such as mortality and preventable deaths. At least two authors assessed eligibility for inclusion and risk of bias, and extracted data from the included studies. As meta-analysis was not possible for all studies, two controlled before-after studies were included in the meta-analysis, and a narrative analysis was conducted for the other studies. After title and abstract sifting, 66 papers were retrieved. After reading the full texts, a total of 24 studies from the USA, UK, Canada, Australia, and the Netherlands were included in this review. In spite of variation in study specifications, most were before-after studies with a high risk of bias. Although a reduction in mortality was shown in most studies, only two studies were eligible for meta-analysis, and the results showed a significant reduction in mortality after implementation of an organized trauma system (odds ratio 0.840, 95% confidence interval 0.756-0.924; P = 0.00). Correlation was found between a regionalized network of trauma care and a reduction in trauma-related mortality, based on studies that did not exclude the effects of other concurrent changes on observed reductions. It is recommended that more studies with robust research designs should be conducted in a more diverse range of countries to assess the effectiveness of regionalization. Despite this limitation, the present findings support the regionalization of trauma care services. Copyright © 2016 The Royal Society for Public Health. Published by Elsevier Ltd.

Noise-induced hearing loss (NIHL) is a growing health issue, with costly treatment and lost quality of life. Here we establish Drosophila melanogaster as an inexpensive, flexible, and powerful genetic model system for NIHL. We exposed flies to acoustic trauma and quantified physiological and anatomical effects. Trauma significantly reduced sound-evoked potential (SEP) amplitudes and increased SEP latencies in control genotypes. SEP amplitude but not latency effects recovered after 7 d. Although trauma produced no gross morphological changes in the auditory organ (Johnston’s organ), mitochondrial cross-sectional area was reduced 7 d after exposure. In nervana 3 heterozygous flies, which slightly compromise ion homeostasis, trauma had exaggerated effects on SEP amplitude and mitochondrial morphology, suggesting a key role for ion homeostasis in resistance to acoustic trauma. Thus, Drosophila exhibit acoustic trauma effects resembling those found in vertebrates, including inducing metabolic stress in sensory cells. This report of noise trauma in Drosophila is a foundation for studying molecular and genetic sequelae of NIHL. PMID:24003166

Accidental hypothermia, acidosis, and coagulopathy represent the lethal triad in severely injured patients. Therapeutic hypothermia however is commonly used in transplantations, cardiac and neurosurgical surgery, or after cardiac arrest. However, the effects of therapeutic hypothermia on the coagulation system following multiple trauma need to be elucidated. In a porcine model of multiple trauma including blunt chest injury, liver laceration, and hemorrhagic shock followed by fluid resuscitation, the influence of therapeutic hypothermia on coagulation was evaluated. A total of 40 pigs were randomly assigned to sham (only anesthesia) or trauma groups receiving either hypothermia or normothermia. Each group consisted of 10 pigs. Analyzed parameters were cell count (red blood cells, platelets), pH, prothrombin time (PT), fibrinogen concentration, and analysis with ROTEM and Multiplate. Trauma and consecutive fluid resuscitation resulted in impaired coagulation parameters (cell count, pH, PT, fibrinogen, ROTEM, and platelet function). During hypothermia, coagulation parameters measured at 37°C, such as PT, fibrinogen, thrombelastometry measurements, and platelet function, showed no significant differences between normothermic and hypothermic animals in both trauma groups. Additional analyses of thrombelastometry at 34°C during hypothermia showed significant differences for clotting time and clot formation time but not for maximum clot firmness. We were not able to detect macroscopic or petechial bleeding in both trauma groups. Based on the results of the present study we suggest that mild hypothermia can be safely performed after stabilization following major trauma. Mild hypothermia has effects on the coagulation system but does not aggravate trauma-induced coagulopathy in our model. Before hypothermic treatment can be performed in the clinical setting, additional experiments with prolonged and deeper hypothermia to exclude detrimental effects are required.

Trauma scoring systems and databases.

This review considers current trauma scoring systems and databases and their relevance to improving patient care. Single physiological measures such as systolic arterial pressure have limited ability to diagnose severe trauma by reflecting raised intracranial pressure, or significant haemorrhage. The Glasgow coma score has the greatest prognostic value in head-injured and other trauma patients. Trauma triage tools and imaging decision rules-using combinations of physiological cut-off measures with mechanism of injury and other categorical variables-bring both increased sophistication and increased complexity. It is important for clinicians and managers to be aware of the diagnostic properties (over- and under-triage rates) of any triage tool or decision rule used in their trauma system. Trauma registries are able to collate definitive injury descriptors and use survival prediction models to guide trauma system governance, through individual patient review and case-mix-adjusted benchmarking of hospital and network performance with robust outlier identification. Interrupted time series allow observation in the changes in care processes and outcomes at national level, which can feed back into clinical quality-based commissioning of healthcare. Registry data are also a valuable resource for trauma epidemiological and comparative effectiveness research studies. © The Author 2014.

Summary According to the Global Burden of Disease, trauma is now responsible for five million deaths each year. High-income countries have made great strides in reducing trauma-related mortality figures but low–middle-income countries have been left behind with high trauma-related fatality rates, primarily in the younger population. Much of the progress high-income countries have made in managing trauma rests on advances developed in their armed forces. This analysis looks at the recent advances in high-income military trauma systems and the potential transferability of those developments to the civilian health systems particularly in low–middle-income countries. It also evaluates some potential lifesaving trauma management techniques, proven effective in the military, and the barriers preventing these from being implemented in civilian settings.

Physiological parameters are crucial for the caring of trauma patients. There is a significant loss of prehospital vital signs data of patients during handover between prehospital and in-hospital teams. Effective strategies for reducing the loss remain a challenging research area. We tested whether the newly developed electronic automated prehospital vital signs chart sharing system would increase the amount of prehospital vital signs data shared with a remote trauma center prior to hospital arrival. Fifty trauma patients, transferred to a level I trauma center in Japan, were studied. The primary outcome variable was the number of prehospital vital signs shared with the trauma center prior to hospital arrival. The prehospital vital signs chart sharing system significantly increased the number of prehospital vital signs, including blood pressure, heart rate, and oxygen saturation, shared with the in-hospital team at a remote trauma center prior to patient arrival at the hospital (P < .0001). There were significant differences in prehospital vital signs during ambulance transfer between patients who had severe bleeding and non-severe bleeding within 24 hours after injury onset. Vital signs data collected during ambulance transfer via patient monitors could be automatically converted to easily visible patient charts and effectively shared with the remote trauma center prior to hospital arrival. The prehospital vital signs chart sharing system increased the number of precise vital signs shared prior to patient arrival at the hospital, which can potentially contribute to better trauma care without increasing labor and reduce information loss during clinical handover.

Trauma leads to deleterious effects on individuals and families causing many to seek treatment from social work practitioners across systems of care. Trauma comes in all forms, from community violence to domestic violence, including physical and sexual abuse of children and violence among intimate partners that leaves its victims devastatingly impacted. Women make up the majority of survivors of intimate partner violence (IPV) with studies revealing significant associated mental health problems. Social workers are bound to work with survivors of IPV and must be prepared to deliver effective trauma-informed services. While trauma-specific services exist for specific populations, researchers are finding that negative events in childhood and in family functioning can impact individuals' lives in negative ways thus having implications for treatment across systems. For women survivors of IPV, the traumatic stress may be cumulative with varied emotional and mental health impacts that may force them to seek services across systems, not just domestic violence specific systems. As such it is imperative that social workers increase awareness of trauma, its impact on women, and the importance of the approach and environment in which they provide services. In this article the author aims to broaden social workers knowledge of the use of a TIC approach developed by the Substance Abuse and Mental Health Services Administration that's applicable across systems of care, particularly when working with women survivors of IPV.

The blunt trauma performance of fabric systems against 9 mm bullets is reported. Three shots were fired at each fabric system with impact velocity of 367+-9 m/s and the depth of indentation on the modeling clay backing was measured. The results showed that 18-layer and 21-layer all-neat fabric systems failed the blunt trauma test. However, fabric systems with natural rubber (NR) latex coated fabric layers gave lower blunt trauma of between 25-32 mm indentation depths. Deformations on the neat fabrics upon impact were identified as broken yarns, yarn stretching and yarn pull-out. Deflections of the neat fabrics were more localised.more » For the NR latex coated fabric layers, no significant deformation can be observed except for peeled-off regions of the NR latex film at the back surface of the last layer. From the study, it can be said that the NR latex coated fabric layers were effective in reducing the blunt trauma of fabric systems.« less

Helicopter transport: help or hindrance?

PubMed

Plevin, Rebecca E; Evans, Heather L

2011-12-01

Traumatic injury continues to be a significant cause of morbidity and mortality in the year 2011. In addition, the healthcare expenditures and lost years of productivity represent significant economic cost to the affected individuals and their communities. Helicopters have been used to transport trauma patients for the past 40 years, but there are conflicting data on the benefits of helicopter emergency medical service (HEMS) in civilian trauma systems. Debate persists regarding the mortality benefit, cost-effectiveness, and safety of helicopter usage, largely because the studies to date vary widely in design and generalizability to trauma systems serving heterogeneous populations and geography. Strict criteria should be established to determine when HEMS transport is warranted and most likely to positively affect patient outcomes. Individual trauma systems should conduct an assessment of their resources and needs in order to most effectively incorporate helicopter transport into their triage model. Research suggests that HEMS improves mortality in certain subgroups of trauma patients, both after transport from the scene of injury and following interfacility transport. Studies examining the cost-effectiveness of HEMS had mixed results, but the majority found that it is a cost-effective tool. Safety remains an issue of contention with HEMS transport, as helicopters are associated with significant safety risk to the crew and patient. However, this risk may be justified provided there is a substantial mortality benefit to be gained. Recent studies suggest that strict criteria should be established to determine when helicopter transport is warranted and most likely to positively affect patient outcomes. Individual trauma systems should conduct an assessment of their resources and needs in order to most effectively incorporate HEMS into their triage model. This will enable regional hospitals to determine if the costs and safety risks associated with HEMS are worthwhile given the potential benefits to patient morbidity and mortality.

Development of a statewide trauma registry using multiple linked sources of data.

Clark, D. E.

1993-01-01

In order to develop a cost-effective method of injury surveillance and trauma system evaluation in a rural state, computer programs were written linking records from two major hospital trauma registries, a statewide trauma tracking study, hospital discharge abstracts, death certificates, and ambulance run reports. A general-purpose database management system, programming language, and operating system were used. Data from 1991 appeared to be successfully linked using only indirect identifying information. Familiarity with local geography and the idiosyncracies of each data source were helpful in programming for effective matching of records. For each individual case identified in this way, data from all available sources were then merged and imported into a standard database format. This inexpensive, population-based approach, maintaining flexibility for end-users with some database training, may be adaptable for other regions. There is a need for further improvement and simplification of the record-linkage process for this and similar purposes. PMID:8130556

Intergenerational Trauma in Refugee Families: A Systematic Review

2016-01-01

Although a robust literature describes the intergenerational effects of traumatic experiences in various populations, evidence specific to refugee families is scattered and contains wide variations in approaches for examining intergenerational trauma. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria, the purpose of this systematic review was to describe the methodologies and findings of peer-reviewed literature regarding intergenerational trauma in refugee families. In doing so we aimed to critically examine how existing literature characterizes refugee trauma, its long-term effects on descendants, and psychosocial processes of transmission in order to provide recommendations for future research. The results highlight populations upon which current evidence is based, conceptualizations of refugee trauma, effects of parental trauma transmission on descendants’ health and well-being, and mechanisms of transmission and underlying meanings attributed to parental trauma in refugee families. Greater methodological rigor and consistency in future evidence-based research is needed to inform supportive systems that promote the health and well-being of refugees and their descendants.

Emerging technologies for pediatric and adult trauma care.

PubMed

Moulton, Steven L; Haley-Andrews, Stephanie; Mulligan, Jane

2010-06-01

Current Emergency Medical Service protocols rely on provider-directed care for evaluation, management and triage of injured patients from the field to a trauma center. New methods to quickly diagnose, support and coordinate the movement of trauma patients from the field to the most appropriate trauma center are in development. These methods will enhance trauma care and promote trauma system development. Recent advances in machine learning, statistical methods, device integration and wireless communication are giving rise to new methods for vital sign data analysis and a new generation of transport monitors. These monitors will collect and synchronize exponentially growing amounts of vital sign data with electronic patient care information. The application of advanced statistical methods to these complex clinical data sets has the potential to reveal many important physiological relationships and treatment effects. Several emerging technologies are converging to yield a new generation of smart sensors and tightly integrated transport monitors. These technologies will assist prehospital providers in quickly identifying and triaging the most severely injured children and adults to the most appropriate trauma centers. They will enable the development of real-time clinical support systems of increasing complexity, able to provide timelier, more cost-effective, autonomous care.

The most effective use of trauma center resources helps reduce morbidity and mortality, while saving costs. Identifying critical infrastructure characteristics, patient characteristics and staffing components of a trauma center associated with the proportion of patients needing major trauma care will help planners create better systems for patient care. We used the 2009 National Trauma Data Bank-Research Dataset to determine the proportion of critically injured patients requiring the resources of a trauma center within each Level I-IV trauma center (n=443). The outcome variable was defined as the portion of treated patients who were critically injured. We defined the need for critical trauma resources and interventions ("trauma center need") as death prior to hospital discharge, admission to the intensive care unit, or admission to the operating room from the emergency department as a result of acute traumatic injury. Generalized Linear Modeling (GLM) was used to determine how hospital infrastructure, staffing Levels, and patient characteristics contributed to trauma center need. Nonprofit Level I and II trauma centers were significantly associated with higher levels of trauma center need. Trauma centers that had a higher percentage of transferred patients or a lower percentage of insured patients were associated with a higher proportion of trauma center need. Hospital infrastructure characteristics, such as bed capacity and intensive care unit capacity, were not associated with trauma center need. A GLM for Level III and IV trauma centers showed that the number of trauma surgeons on staff was associated with trauma center need. Because the proportion of trauma center need is predominantly influenced by hospital type, transfer frequency, and insurance status, it is important for administrators to consider patient population characteristics of the catchment area when planning the construction of new trauma centers or when coordinating care within state or regional trauma systems.

Audit filters for improving processes of care and clinical outcomes in trauma systems.

Traumatic injuries represent a considerable public health burden with significant personal and societal costs. The care of the severely injured patient in a trauma system progresses along a continuum that includes numerous interventions being provided by a multidisciplinary group of healthcare personnel. Despite the recent emphasis on quality of care in medicine, there has been little research to direct trauma clinicians and administrators on how optimally to monitor and improve upon the quality of care delivered within a trauma system. Audit filters are one mechanism for improving quality of care and are defined as specific clinical processes or outcomes of care that, when they occur, represent unfavorable deviations from an established norm and which prompt review and feedback. Although audit filters are widely utilized for performance improvement in trauma systems they have not been subjected to systematic review of their effectiveness. To determine the effectiveness of using audit filters for improving processes of care and clinical outcomes in trauma systems. Our search strategy included an electronic search of the Cochrane Injuries Group Specialized Register, the Cochrane EPOC Group Specialized Register, CENTRAL (The Cochrane Library 2008, Issue 4), MEDLINE, PubMed, EMBASE, CINAHL, and ISI Web of Science: (SCI-EXPANDED and CPCI-S). We handsearched the Journal of Trauma, Injury, Annals of Emergency Medicine, Academic Emergency Medicine, and Injury Prevention. We searched two clinical trial registries: 1) The World Health Organization International Clinical Trials Registry Platform and, 2) Clinical Trials.gov. We also contacted content experts for further articles. The most recent electronic search was completed in December 2008 and the handsearch was completed up to February 2009. We searched for randomized controlled trials, controlled clinical trials, controlled before-and-after studies, and interrupted time series studies that used audit filters as an intervention for improving processes of care, morbidity, or mortality for severely injured patients. Two authors independently screened the search results, applied inclusion criteria, and extracted data. There were no studies identified that met the inclusion criteria for this review. We were unable to identify any studies of sufficient methodological quality to draw conclusions regarding the effectiveness of audit filters as a performance improvement intervention in trauma systems. Future research using rigorous study designs should focus on the relative effectiveness of audit filters in comparison to alternative quality improvement strategies at improving processes of care, functional outcomes, and mortality for injured patients.

A stratified response system for the emergency management of the severely injured.

A decade ago, there were justifiable criticisms of the delivery of emergency care for injured patients in accident and emergency departments in the UK. To address this, a trauma management system was developed in 1991 at Alder Hey Hospital, Liverpool. This includes a trauma team, communication system, management guidelines and quality assurance. On admission to the accident and emergency department, injured patients are triaged to one of three levels of injury severity, and a multidisciplinary team lead by a paediatric surgeon or senior accident and emergency department physician is activated. The level of injury severity determines the composition of the trauma team. A care pathway based on ATLS/APLS principles has been developed. The response process as well patient management are documented and reviewed at a monthly audit meeting. Currently, more than 80% of eligible patients are managed using the trauma system, with an over-triage rate of about 25%. Regular modifications to the trauma system since its inception in 1991 have resulted in an efficient and effective management structure. Stratification of the trauma response has minimised unnecessary use of the multidisciplinary trauma team and ensures that mobilisation and use of hospital staff and resources are tailored to the needs of the injured patient. Although developed in a specialist children's hospital, the system could be adapted for any acute hospital.

Exposure to 100% Oxygen Abolishes the Impairment of Fracture Healing after Thoracic Trauma

In polytrauma patients a thoracic trauma is one of the most critical injuries and an important trigger of post-traumatic inflammation. About 50% of patients with thoracic trauma are additionally affected by bone fractures. The risk for fracture malunion is considerably increased in such patients, the pathomechanisms being poorly understood. Thoracic trauma causes regional alveolar hypoxia and, subsequently, hypoxemia, which in turn triggers local and systemic inflammation. Therefore, we aimed to unravel the role of oxygen in impaired bone regeneration after thoracic trauma. We hypothesized that short-term breathing of 100% oxygen in the early post-traumatic phase ameliorates inflammation and improves bone regeneration. Mice underwent a femur osteotomy alone or combined with blunt chest trauma 100% oxygen was administered immediately after trauma for two separate 3 hour intervals. Arterial blood gas tensions, microcirculatory perfusion and oxygenation were assessed at 3, 9 and 24 hours after injury. Inflammatory cytokines and markers of oxidative/nitrosative stress were measured in plasma, lung and fracture hematoma. Bone healing was assessed on day 7, 14 and 21. Thoracic trauma induced pulmonary and systemic inflammation and impaired bone healing. Short-term exposure to 100% oxygen in the acute post-traumatic phase significantly attenuated systemic and local inflammatory responses and improved fracture healing without provoking toxic side effects, suggesting that hyperoxia could induce anti-inflammatory and pro-regenerative effects after severe injury. These results suggest that breathing of 100% oxygen in the acute post-traumatic phase might reduce the risk of poorly healing fractures in severely injured patients. PMID:26147725

Trauma care systems in Saudi Arabia: an agenda for action

2010-01-01

Saudi Arabia is undergoing a rapid population growth that along with improved socioeconomics has led many individuals to own a car or even a number of cars per family, resulting in a greater number of vehicles on the roads. The reduced focus on good public transportation systems and the dependence on cars for transportation have created a diversity of drivers who are unfamiliar with the local driving rules and lack the basic skills for safe driving. This is in addition to some young drivers who frequently violate traffic laws and tend to speed most of the time. This unplanned expansion in road traffic has resulted in more car accidents, injuries, disabilities, and deaths. Accompanying that is an increased socioeconomic burden, depletion of human resources, emotional and psychological stress on families, and a strain on healthcare facilities. If this continues without prompt intervention, it will lead to increased insurance premiums and may become unmanageable. To minimize this impact, a national or regional multidisciplinary trauma system has to be developed and implemented. A trauma system is a preplanned, comprehensive, and coordinated regional injury response network that includes all facilities with the capability to care for the injured. Essential components of the system include trauma prevention, prehospital care, hospital care, rehabilitation, system administration, trauma care education and training, trauma care evaluation and quality improvement, along with the participation of society. Research has documented a significant decrease in morbidity and mortality from trauma after the implementation of such systems, depending on their efficiency. The purpose of this review is to discuss the problem of road traffic accidents in this country and address the trauma care system as an effective solution. PMID:20103958

Evaluation of a Mature Trauma System

Durham, Rodney; Pracht, Etienne; Orban, Barbara; Lottenburg, Larry; Tepas, Joseph; Flint, Lewis

2006-01-01

Introduction: An effective trauma system should offer patients triaged to a trauma center (TC) a survival advantage and cost-effective treatment. Three questions were asked: 1) Does treatment at a TC versus a nontrauma center (NTC) improve survival? 2) Is the system cost-effective? 3) Is access to the system equitable? Methods: The 2003 Florida discharge database identified patients with ICD9 codes 800 to 959. Survival risk ratios (SRR) were calculated using1999–2000 data and ICISS were produced for each code. Using 2003 data, mortality rates were calculated for matched patients at TCs and NTCs. Instrumental variables methodology was used to account for differences in mortality risks of patients triaged to TCs versus NTCs. Logistic regression analysis was used to determine differences in mortality. Charge/cost ratios were analyzed to compute the cost care and cost/life saved. Accessibility to a TC within 85 minutes of injury was assessed. Results: Treatment at a TC was associated with an 18% reduction in mortality. Mean costs of care in TCs and NTCs were $11,910 and $6019, respectively. Dividing the mean cost difference by the reduction in mortality yields a cost of $34,887/life saved. A total of 42% of patients returned to work within 24 months of injury. Using an expected median of 19 years of employment for a 33-year-old individual and proposed state funding figures for the trauma system, a life saved results in an approximate annual cost to the state of between $100 and $500. Currently, 95% of citizens of the state have access to the trauma system within 85 minutes of injury; however, only 38% of trauma patients are triaged to a TC. Addition of 3 TCs would increase these percentages to 99% and 65%. Conclusions: Triage to a Florida TC is associated with a decreased risk of death. Moreover, cost/life year saved is favorable when compared with societal expenditures for other health problems. Improved deployment of TCs is necessary to optimize access. This assessment methodology is a useful model for evaluation of mature trauma systems. PMID:16772781

Accurate and effective diagnosis of actual injury severity can be problematic in trauma patients. Inherent physiologic compensatory mechanisms may prevent accurate diagnosis and mask true severity in many circumstances. The objective of this project was the development and validation of a multiparameter machine learning algorithm and system capable of predicting the need for life-saving interventions (LSIs) in trauma patients. Statistics based on means, slopes, and maxima of various vital sign measurements corresponding to 79 trauma patient records generated over 110,000 feature sets, which were used to develop, train, and implement the system. Comparisons among several machine learning models proved that a multilayer perceptron would best implement the algorithm in a hybrid system consisting of a machine learning component and basic detection rules. Additionally, 295,994 feature sets from 82 h of trauma patient data showed that the system can obtain 89.8 % accuracy within 5 min of recorded LSIs. Use of machine learning technologies combined with basic detection rules provides a potential approach for accurately assessing the need for LSIs in trauma patients. The performance of this system demonstrates that machine learning technology can be implemented in a real-time fashion and potentially used in a critical care environment.

The intergenerational effects of Indian Residential Schools: Implications for the concept of historical trauma

PubMed Central

Matheson, Kimberly; Anisman, Hymie

2014-01-01

The current paper reviews research that has explored the intergenerational effects of the Indian Residential School (IRS) system in Canada, in which Aboriginal children were forced to live at schools where various forms of neglect and abuse were common. Intergenerational IRS trauma continues to undermine the well-being of today’s Aboriginal population, and having a familial history of IRS attendance has also been linked with more frequent contemporary stressor experiences and relatively greater effects of stressors on well-being. It is also suggested that familial IRS attendance across several generations within a family appears to have cumulative effects. Together, these findings provide empirical support for the concept of historical trauma, which takes the perspective that the consequences of numerous and sustained attacks against a group may accumulate over generations and interact with proximal stressors to undermine collective well-being. As much as historical trauma might be linked to pathology, it is not possible to go back in time to assess how previous traumas endured by Aboriginal peoples might be related to subsequent responses to IRS trauma. Nonetheless, the currently available research demonstrating the intergenerational effects of IRSs provides support for the enduring negative consequences of these experiences and the role of historical trauma in contributing to present day disparities in well-being.

Trauma systems operate on the principle that people with severe injuries require special medical capabilities if they are to have their best chance of recovery. However, optimal trauma care is threatened by the problems of inadequate financial reimbursement. This threatens the ability to deliver trauma patient care. A variety of strategies is necessary to continue to provide care. Two specific nursing role innovations provide the opportunity to improve the ability to provide coordinated, efficient, and cost-effective quality care.

Helicopter emergency medical services (EMS) has become a well-established component of modern trauma systems. It is an expensive, limited resource with potential safety concerns. Helicopter EMS activation criteria intended to increase efficiency and reduce inappropriate use remain elusive and difficult to measure. This study evaluates the effect of statewide field trauma triage changes on helicopter EMS use and patient outcomes. Data were extracted from the helicopter EMS computer-aided dispatch database for in-state scene flights and from the state Trauma Registry for all trauma patients directly admitted from the scene or transferred to trauma centers from July 1, 2000, to June 30, 2011. Computer-aided dispatch flights were analyzed for periods corresponding to field triage protocol modifications intended to improve system efficiency. Outcomes were separately analyzed for trauma registry patients by mode of transport. The helicopter EMS computer-aided dispatch data set included 44,073 transports. There was a statewide decrease in helicopter EMS usage for trauma patients of 55.9%, differentially affecting counties closer to trauma centers. The Trauma Registry data set included 182,809 patients (37,407 helicopter transports, 128,129 ambulance transports, and 17,273 transfers). There was an increase of 21% in overall annual EMS scene trauma patients transported; ground transports increased by 33%, whereas helicopter EMS transports decreased by 49%. Helicopter EMS patient acuity increased, with an attendant increase in patient mortality. However, when standardized with W statistics, both helicopter EMS- and ground-transported trauma patients showed sustained improvement in mortality. Modifications to state protocols were associated with decreased helicopter EMS use and overall improved trauma patient outcomes. Copyright © 2015 American College of Emergency Physicians.

There are 27 receiving trauma hospitals in the Republic of Ireland. There has not been an audit system in place to monitor and measure processes and outcomes of care. The National Office of Clinical Audit (NOCA) is now working to implement Major Trauma Audit (MTA) in Ireland using the well-established National Health Service (NHS) UK Trauma Audit and Research Network (TARN). The aim of this report is to highlight the implementation process of MTA in Ireland to raise awareness of MTA nationally and share lessons that may be of value to other health systems undertaking the development of MTA. The National Trauma Audit Committee of the Royal College of Surgeons in Ireland, consisting of champions and stakeholders in trauma care, in 2010 advised on the adaptation of TARN for Ireland. In 2012, the Emergency Medicine Program endorsed TARN and in setting up the National Emergency Medicine Audit chose MTA as the first audit project. A major trauma governance group was established representing stakeholders in trauma care, a national project co-ordinator was recruited and a clinical lead nominated. Using Survey Monkey, the chief executives of all trauma receiving hospitals were asked to identify their hospital's trauma governance committee, trauma clinical lead and their local trauma data co-ordinator. Hospital Inpatient Enquiry systems were used to identify to hospitals an estimate of their anticipated trauma audit workload. There are 25 of 27 hospitals now collecting data using the TARN trauma audit platform. These hospitals have provided MTA Clinical Leads, allocated data co-ordinators and incorporated MTA reports formally into their clinical governance, quality and safety committee meetings. There has been broad acceptance of the NOCA escalation policy by hospitals in appreciation of the necessity for unexpected audit findings to stimulate action. Major trauma audit measures trauma patient care processes and outcomes of care to drive quality improvement at hospital and national level. MTA will facilitate the strategic development of trauma care in Ireland by monitoring processes and outcomes and the effects of changes in trauma service provision. Copyright © 2015 Elsevier Ltd.

Families exposed to urban poverty face a disproportionate risk of exposure to repeated trauma. Repeated exposures can lead to severe and chronic reactions in multiple family members with effects that ripple throughout the family system. Interventions for distressed families residing in traumatic contexts, such as low-income, urban settings are desperately needed. This report presents preliminary data in support of Strengthening Family Coping Resources, a trauma-focused, multifamily, skill-building intervention. Strengthening Family Coping Resources is designed for families living in traumatic contexts with the goal of reducing symptoms of posttraumatic stress disorder and other trauma-related disorders in children and caregivers. Results from open trials suggest Strengthening Family Coping Resources is a feasible intervention with positive effects on children's symptoms of trauma-related distress.

Hearing loss induces plasticity in excitatory and inhibitory neurotransmitter systems in auditory brain regions. Excitatory-inhibitory balance is also influenced by a range of neuromodulatory regulatory systems, but less is known about the effects of auditory damage on these networks. In this work, we studied the effects of acoustic trauma on neuromodulatory plasticity in the auditory midbrain of CBA/J mice. Quantitative PCR was used to measure the expression of serotonergic and GABAergic receptor genes in the inferior colliculus (IC) of mice that were unmanipulated, sham controls with no hearing loss, and experimental individuals with hearing loss induced by exposure to a 116 dB, 10 kHz pure tone for 3 hours. Acoustic trauma induced substantial hearing loss that was accompanied by selective upregulation of two serotonin receptor genes in the IC. The Htr1B receptor gene was upregulated tenfold following trauma relative to shams, while the Htr1A gene was upregulated threefold. In contrast, no plasticity in serotonin receptor gene expression was found in the hippocampus, a region also innervated by serotonergic projections. Analyses in the IC demonstrated that acoustic trauma also changed the coexpression of genes in relation to each other, leading to an overexpression of Htr1B compared to other genes.. These data suggest that acoustic trauma induces serotonergic plasticity in the auditory system, and that this plasticity may involve comodulation of functionally-linked receptor genes. PMID:24997228

Although the juvenile crime rate has generally declined, the involvement of girls in the juvenile justice system has been increasing. Possible explanations for this gender difference include the impact of exposure to trauma and mental health needs on developmental pathways and the resulting influence of youth's involvement in the justice system. This study examined the influence of gender, mental health needs and trauma on the risk of out-of-home placement for juvenile offenders. The sample included youth referred to three urban juvenile probation departments in Texas between January 1, 2007 and December 31, 2008 and who received state-mandated mental health screening (N = 34,222; 30.1 % female). The analysis revealed that, for both genders, elevated scores on the seven factor-analytically derived subscales of a mental health screening instrument (Alcohol and Drug Use, Depressed-Anxious, Somatic Complaints, Suicidal Ideation, Thought Disturbance, and Traumatic Experiences), especially related to past traumatic experiences, influenced how deeply juveniles penetrated the system. The findings suggest that additional research is needed to determine the effectiveness of trauma interventions and the implementation of trauma informed systems for youth involved with the juvenile justice system.

Effective trauma resuscitation requires efficient and coordinated care from a team of providers; however, providers are rarely instructed on how to be effective members of trauma teams. Team-based learning using Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS) has been shown to improve team dynamics among practicing professionals, including physicians and nurses. The impact of TeamSTEPPS on students being trained in trauma management in an undergraduate health professional program is currently unknown. We sought to determine the impact of TeamSTEPPS on team dynamics among undergraduate students being trained in trauma resuscitation. We enrolled teams of undergraduate health professional students from four programs: nursing, physician assistant, radiologic science, and respiratory care. After completing an online training on trauma resuscitation principles, the participants completed a trauma resuscitation scenario. The participants then received teamwork training using TeamSTEPPS and completed a second trauma resuscitation scenario identical to the first. All resuscitations were recorded and scored offline by two blinded research assistants using both the Team Emergency Assessment Measure (TEAM) and Trauma Team Performance Observation Tool (TPOT) scoring systems. Pre-test and post-test TEAM and TPOT scores were compared. We enrolled a total of 48 students in 12 teams. Team leadership, situational monitoring, and overall communication improved with TeamSTEPPS training (P=0.04, P=0.02, and P=0.03, respectively), as assessed by the TPOT scoring system. TeamSTEPPS also improved the team's ability to prioritize tasks and work together to complete tasks in a rapid manner (P<0.01 and P=0.02, respectively) as measured by TEAM. Incorporating TeamSTEPPS into trauma team education leads to improved TEAM and TPOT scores among undergraduate health professionals.

The use of negative pressure wound therapy (NPWT) in civilian and military wounds is found effective in promoting granulation tissue, decreasing exudate and improving patient comfort. The Use of gauze-based NPWT is increasing in civilian trauma cases with availability of proprietary systems using gauze as filler material rather than the traditionally used reticulated open-cell foam. Military trauma wounds differ from civilian trauma wounds in energy of impact, degree and nature of contamination as well as the hostile environments. The Use of gauze as filler material for NPWT in military trauma wounds is less well studied. This study is a retrospective analysis of use of improvised gauze-based NPWT in military trauma wounds. The whole assembly was constructed from commonly available operation theatre supplies and no proprietary system was used. Results were very encouraging and the use of this improvised method can be useful and cheap alternative to costly proprietary systems. © 2013 The Authors.

An essential but often overlooked component to promoting trauma-informed care within the child welfare system is educating and empowering foster, adoptive, and kinship caregivers (resource parents) with a trauma-informed perspective to use in their parenting as well as when advocating for services for their child. In this first evaluation of the National Child Traumatic Stress Network's trauma-informed parenting workshop (Caring for Children who Have Experienced Trauma, also known as the Resource Parent Curriculum), participant acceptance and satisfaction and changes in caregiver knowledge and beliefs related to trauma-informed parenting were examined. Data from 159 ethnically diverse resource parents were collected before and after they participated in the workshop. Results demonstrate that kinship and nonkinship caregivers showed significant increases in their knowledge of trauma-informed parenting and their perceived self-efficacy parenting a child who experienced trauma. Nonkinship caregivers increased on their willingness to tolerate difficult child behaviors, whereas kinship caregivers did not show a significant change. Participants also demonstrated high levels of satisfaction with the workshop. Although these preliminary results are important as the first empirical study supporting the workshop's effectiveness, the limitations of this study and the directions for future research are discussed. © The Author(s) 2015.

Trauma systems and the costs of trauma care.

Goldfarb, M G; Bazzoli, G J; Coffey, R M

OBJECTIVE. This study examines the cost of providing trauma services in trauma centers organized by publicly administered trauma systems, compared to hospitals not part of a formal trauma system. DATA SOURCES AND STUDY SETTING. Secondary administrative discharge abstracts for a national sample of severely injured trauma patients in 44 trauma centers and 60 matched control hospitals for the year 1987 were used. STUDY DESIGN. Retrospective univariate and multivariate analyses were conducted to examine the impact of formal trauma systems and trauma center designation on the costs of treating trauma patients. Key dependent variables included length of stay, charge per day per patient, and charge per hospital stay. Key impact variables were type of trauma system and level of trauma designation. Control variables included patient, hospital, and community characteristics. DATA COLLECTION/EXTRACTION METHODS. Data were selected for hospitals based on (1) a large national hospital discharge database, the Hospital Cost and Utilization Project, 1980-1987 (HCUP-2) and (2) a special survey of trauma systems and trauma designation undertaken by the Hospital Research and Educational Trust of the American Hospital Association. PRINCIPAL FINDINGS. The results show that publicly designated Level I trauma centers, which are the focal point of most trauma systems, have the highest charge per case, the highest average charge per day, and similar or longer average lengths of stay than other hospitals. These findings persist after controlling for patient injury and health status, and for demographic characteristics and hospital and community characteristics. CONCLUSIONS. Prior research shows that severely injured trauma patients have greater chances of survival when treated in specialized trauma centers. However, findings here should be of concern to the many states developing trauma systems since the high costs of Level I centers support limiting the number of centers designated at this level and/or reconsidering the requirements placed on these centers.

The intergenerational effects of Indian Residential Schools: implications for the concept of historical trauma.

The current paper reviews research that has explored the intergenerational effects of the Indian Residential School (IRS) system in Canada, in which Aboriginal children were forced to live at schools where various forms of neglect and abuse were common. Intergenerational IRS trauma continues to undermine the well-being of today's Aboriginal population, and having a familial history of IRS attendance has also been linked with more frequent contemporary stressor experiences and relatively greater effects of stressors on well-being. It is also suggested that familial IRS attendance across several generations within a family appears to have cumulative effects. Together, these findings provide empirical support for the concept of historical trauma, which takes the perspective that the consequences of numerous and sustained attacks against a group may accumulate over generations and interact with proximal stressors to undermine collective well-being. As much as historical trauma might be linked to pathology, it is not possible to go back in time to assess how previous traumas endured by Aboriginal peoples might be related to subsequent responses to IRS trauma. Nonetheless, the currently available research demonstrating the intergenerational effects of IRSs provides support for the enduring negative consequences of these experiences and the role of historical trauma in contributing to present day disparities in well-being. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Background The American College of Surgeons Committee on Trauma sets national targets for the accuracy of field trauma triage at ≥ 95% sensitivity and ≥ 65% specificity, yet the cost-effectiveness of realizing these goals is unknown. We evaluated the cost-effectiveness of current field trauma triage practices compared to triage strategies consistent with the national targets. Study Design This was a cost-effectiveness analysis using data from 79,937 injured adults transported by 48 emergency medical services (EMS) agencies to 105 trauma and non-trauma hospitals in 6 regions of the Western U.S. from 2006 through 2008. Incremental differences in survival, quality adjusted life years (QALYs), costs, and the incremental cost-effectiveness ratio (ICER; costs per QALY gained) were estimated for each triage strategy over a 1-year and lifetime horizon using a decision analytic Markov model. We considered an ICER threshold of less than $100,000 to be cost-effective. Results For these 6 regions, a high sensitivity triage strategy consistent with national trauma policy (sensitivity 98.6%, specificity 17.1%) would cost $1,317,333 per QALY gained, while current triage practices (sensitivity 87.2%, specificity 64.0%) cost $88,000 per QALY gained compared to a moderate sensitivity strategy (sensitivity 71.2%, specificity 66.5%). Refining EMS transport patterns by triage status improved cost-effectiveness. At the trauma system level, a high-sensitivity triage strategy would save 3.7 additional lives per year at a 1-year cost of $8.78 million, while a moderate sensitivity approach would cost 5.2 additional lives and save $781,616 each year. Conclusions A high-sensitivity approach to field triage consistent with national trauma policy is not cost effective. The most cost effective approach to field triage appears closely tied to triage specificity and adherence to triage-based EMS transport practices. PMID:27178369

Trauma continues to be a major health problem worldwide, particularly in the developing world, with high mortality and morbidity. Yet most developing countries lack an organized trauma system. Furthermore, developing countries do not have in place any accreditation process for trauma centers; thus, no accepted standard assessment tools exist to evaluate their trauma services. The aims of this study were to evaluate the trauma system in Albania, using the basic trauma criteria of the American College of Surgeons/Committee on Trauma (ACS/COT) as assessment tools, and to provide the Government with a situational analysis relative to these criteria. We used the ACS/COT basic criteria as assessment tools to evaluate the trauma system in Albania. We conducted a series of semi-structured interviews, unstructured interviews, and focus groups with all stakeholders at the Ministry of Health, at the University Trauma Hospital (UTH) based in Tirana (the capital city), and at ten regional hospitals across the country. Albania has a dedicated national trauma center that serves as the only tertiary center, plus ten regional hospitals that provide some trauma care. However, overall, its trauma system is in need of major reforms involving all essential elements in order to meet the basic requirements of a structured trauma system. The ACS/COT basic criteria can be used as assessment tools to evaluate trauma care in developing countries. Further studies are needed in other developing countries to validate the applicability of these criteria.

The Trauma Time-Out: Evaluating the Effectiveness of Protocol-Based Information Dissemination in the Traumatically Injured Patient.

PubMed

Nolan, Heather R; Fitzgerald, Michael; Howard, Brett; Jarrard, Joey; Vaughn, Danny

Procedural time-outs are widely accepted safety standards that are protocolized in nearly all hospital systems. The trauma time-out, however, has been largely unstudied in the existing literature and does not have a standard protocol outlined by any of the major trauma surgery organizations. The goal of this study was to evaluate our institution's use of the trauma time-out and assess how trauma team members viewed its effectiveness. A multiple-answer survey was sent to trauma team members at a Level I trauma center. Questions included items directed at background, experience, opinions, and write-in responses. Most responders were experienced trauma team members who regularly participated in trauma codes. All respondents noted the total time required to complete the time-out was less than 5 min, with the majority saying it took less than 1 min. Seventy-five percent agreed that trauma time-outs should continue, with 92% noting that it improved understanding of patient presentation and prehospital evaluation. Seventy-seven percent said it improved understanding of other team member's roles, and 75% stated it improved patient care. Subgroups of physicians and nurses were statistically similar; yet, physicians did note that it improved their understanding of the team member's function more frequently than nurses. The trauma time-out can be an excellent tool to improve patient care and team understanding of the incoming trauma patient. Although used widely at multiple levels of trauma institutions, development of a documented protocol can be the next step in creating a unified safety standard.

Molecular mechanisms of inflammation and tissue injury after major trauma-is complement the "bad guy"?

PubMed Central

2011-01-01

Trauma represents the leading cause of death among young people in industrialized countries. Recent clinical and experimental studies have brought increasing evidence for activation of the innate immune system in contributing to the pathogenesis of trauma-induced sequelae and adverse outcome. As the "first line of defense", the complement system represents a potent effector arm of innate immunity, and has been implicated in mediating the early posttraumatic inflammatory response. Despite its generic beneficial functions, including pathogen elimination and immediate response to danger signals, complement activation may exert detrimental effects after trauma, in terms of mounting an "innocent bystander" attack on host tissue. Posttraumatic ischemia/reperfusion injuries represent the classic entity of complement-mediated tissue damage, adding to the "antigenic load" by exacerbation of local and systemic inflammation and release of toxic mediators. These pathophysiological sequelae have been shown to sustain the systemic inflammatory response syndrome after major trauma, and can ultimately contribute to remote organ injury and death. Numerous experimental models have been designed in recent years with the aim of mimicking the inflammatory reaction after trauma and to allow the testing of new pharmacological approaches, including the emergent concept of site-targeted complement inhibition. The present review provides an overview on the current understanding of the cellular and molecular mechanisms of complement activation after major trauma, with an emphasis of emerging therapeutic concepts which may provide the rationale for a "bench-to-bedside" approach in the design of future pharmacological strategies.

Children in the child welfare system comprise a group characterized by exposure to trauma via experiences of maltreatment, under circumstances presenting multiple risk factors for traumatic stress. High rates of posttraumatic stress have been observed in this population. However, there is currently no standard for the universal screening of children in child welfare for trauma exposure and traumatic stress. This study examined the trauma experiences of a sample of maltreated children and whether their child welfare workers were effective screeners of traumatic stress symptoms. Descriptive and correlational analyses were conducted regarding a sample of children (N = 131) with trauma screenings completed by their child welfare workers and clinical measures of traumatic stress symptoms. Four hierarchical regression models were also examined to determine whether workers' screening information regarding child age, trauma exposure history and symptoms of traumatic stress were predictive of outcomes on clinical measures. The analyses revealed complex trauma exposure histories and high rates of traumatic stress symptoms among this generally younger sample of maltreated children. Additionally, the models supported workers' efficacy in screening for symptoms of total posttraumatic stress and specific trauma symptoms of intrusion and avoidance. Workers were less effective in screening for the symptoms of arousal. These findings support the importance of identifying the trauma recovery needs of maltreated children and the utility of child protection workers in assisting with the trauma screening process. Implications are provided for related practice, policy and training efforts in child welfare. Published by Elsevier Ltd.

Cannabinoids and traumatic stress modulation of contextual fear extinction and GR expression in the amygdala-hippocampal-prefrontal circuit.

PubMed

Ganon-Elazar, Eti; Akirav, Irit

2013-09-01

Considerable evidence suggests that cannabinoids modulate the behavioral and physiological response to stressful events. We have recently shown that activating the cannabinoid system using the CB1/CB2 receptor agonist WIN55,212-2 (WIN) in proximity to exposure to single-prolonged stress (SPS), a rat model of emotional trauma, prevented the stress-induced enhancement of acoustic startle response, the impairment in avoidance extinction and the enhanced negative feedback on the hypothalamic-pituitary-adrenal (HPA) axis (Ganon-Elazar and Akirav, 2012). Some of the effects were found to be mediated by CB1 receptors in the basolateral amygdala (BLA). Here we examined whether cannabinoid receptor activation in a putative brain circuit that includes the BLA, hippocampus and prefrontal cortex (PFC), could prevent the effects of traumatic stress on contextual fear extinction and alterations in glucocorticoid receptor (GR) protein levels. We found that: (i) SPS impaired contextual fear extinction tested one week after trauma exposure and that WIN prevented the stress-induced impairment of extinction when microinjected immediately after trauma exposure into the BLA or hippocampus (5 μg), but not when microinjected into the PFC, (ii) the ameliorating effects of WIN on contextual extinction were prevented by blocking GRs in the BLA and hippocampus, and (iii) SPS up regulated GRs in the BLA, PFC and hippocampus and systemic WIN administration (0.5 mg/kg) after trauma exposure normalized GR levels in the BLA and hippocampus, but not in the PFC. Cannabinoid receptor activation in the aftermath of trauma exposure may regulate the emotional response to the trauma and prevent stress-induced impairment of extinction and GR up regulation through the mediation of CB1 receptors in the BLA and hippocampus. Taken together, the findings suggest that the interaction between the cannabinoid and glucocorticoid systems is crucial in the modulation of emotional trauma. Copyright © 2013 Elsevier Ltd.

Psychoneuroimmunology of Early-Life Stress: The Hidden Wounds of Childhood Trauma?

PubMed Central

Danese, Andrea; J Lewis, Stephanie

2017-01-01

The brain and the immune system are not fully formed at birth, but rather continue to mature in response to the postnatal environment. The two-way interaction between the brain and the immune system makes it possible for childhood psychosocial stressors to affect immune system development, which in turn can affect brain development and its long-term functioning. Drawing from experimental animal models and observational human studies, we propose that the psychoneuroimmunology of early-life stress can offer an innovative framework to understand and treat psychopathology linked to childhood trauma. Early-life stress predicts later inflammation, and there are striking analogies between the neurobiological correlates of early-life stress and of inflammation. Furthermore, there are overlapping trans-diagnostic patterns of association of childhood trauma and inflammation with clinical outcomes. These findings suggest new strategies to remediate the effect of childhood trauma before the onset of clinical symptoms, such as anti-inflammatory interventions and potentiation of adaptive immunity. Similar strategies might be used to ameliorate the unfavorable treatment response described in psychiatric patients with a history of childhood trauma. PMID:27629365

Exposure to childhood trauma is a major public health concern and is especially prevalent among children in the child welfare system (CWS). State and tribal CWSs are increasingly focusing efforts on identifying and serving children exposed to trauma through the creation of trauma-informed systems. This evaluation of a statewide initiative in Connecticut describes the strategies used to create a trauma-informed CWS, including workforce development, trauma screening, policy change, and improved access to evidence-based trauma-focused treatments during the initial 2-year implementation period. Changes in system readiness and capacity to deliver trauma-informed care were evaluated using stratified random samples of child welfare staff who completed a comprehensive assessment prior to (N = 223) and 2 years following implementation (N = 231). Results indicated significant improvements in trauma-informed knowledge, practice, and collaboration across nearly all child welfare domains assessed, suggesting system-wide improvements in readiness and capacity to provide trauma-informed care. Variability across domains was observed, and frontline staff reported greater improvements than supervisors/managers in some domains. Lessons learned and recommendations for implementation and evaluation of trauma-informed care in child welfare and other child-serving systems are discussed. © The Author(s) 2016.

Age is a risk factor for death, adverse outcomes, and health care use following trauma. The American College of Surgeons' Trauma Quality Improvement Program (TQIP) has published "best practices" of geriatric trauma care; adoption of these guidelines is unknown. We sought to determine which evidence-based geriatric protocols, including TQIP guidelines, were correlated with decreased mortality in Pennsylvania's trauma centers. PA's level I and II trauma centers self-reported adoption of geriatric protocols. Survey data were merged with risk-adjusted mortality data for patients ≥65 from a statewide database, the Pennsylvania Trauma Systems Foundation (PTSF), to compare mortality outlier status and processes of care. Exposures of interest were center-specific processes of care; outcome of interest was PTSF mortality outlier status. 26 of 27 eligible trauma centers participated. There was wide variation in care processes. Four trauma centers were low outliers; three centers were high outliers for risk-adjusted mortality rates in adults ≥65. Results remained consistent when accounting for center volume. The only process associated with mortality outlier status was age-specific solid organ injury protocols (p = 0.04). There was no cumulative effect of multiple evidence-based processes on mortality rate (p = 0.50). We did not see a link between adoption of geriatric best-practices trauma guidelines and reduced mortality at PA trauma centers. The increased susceptibility of elderly to adverse consequences of injury, combined with the rapid growth rate of this demographic, emphasizes the importance of identifying interventions tailored to this population.

Strategically Leapfrogging Education in Prehospital Trauma Management: Four-Tiered Training Protocols

2016-01-01

Trauma-related injury in fast developing countries are linked to 90% of international mortality rates, which can be greatly reduced by improvements in often non-existent or non-centralized emergency medical systems (EMS)—particularly in the pre-hospital care phase. Traditional trauma training protocols—such as Advanced Trauma Life Support (ATLS), International Trauma Life Support (ITLS), and Basic Life Support (BLS)—have failed to produce an effective pre-hospital ground force of medical first responders. To overcome these barriers, we propose a new four-tiered set of trauma training protocols: Massive Open Online Course (MOOC) Trauma Training, Acute Trauma Training (ATT), Broad Trauma Training (BTT), and Cardiac and Trauma Training (CTT). These standards are specifically differentiated to accommodate the educational and socioeconomic diversity found in fast developing settings, where each free course is taught in native, lay language while ensuring the education standards are maintained by fully incorporating high-fidelity simulation, video-recorded debriefing, and retraining.

Trauma-related injury in fast developing countries are linked to 90% of international mortality rates, which can be greatly reduced by improvements in often non-existent or non-centralized emergency medical systems (EMS)-particularly in the pre-hospital care phase. Traditional trauma training protocols-such as Advanced Trauma Life Support (ATLS), International Trauma Life Support (ITLS), and Basic Life Support (BLS)-have failed to produce an effective pre-hospital ground force of medical first responders. To overcome these barriers, we propose a new four-tiered set of trauma training protocols: Massive Open Online Course (MOOC) Trauma Training, Acute Trauma Training (ATT), Broad Trauma Training (BTT), and Cardiac and Trauma Training (CTT). These standards are specifically differentiated to accommodate the educational and socioeconomic diversity found in fast developing settings, where each free course is taught in native, lay language while ensuring the education standards are maintained by fully incorporating high-fidelity simulation, video-recorded debriefing, and retraining. The innovative pedagogy of this trauma education program utilizes MOOC for global scalability and a "train-the-trainer" approach for exponential growth-both components help fast developing countries reach a critical mass of first responders needed for the base of an evolving EMS.

Prehospital trauma systems are rudimentary in many low- and middle-income countries (LMICs) and require laypersons to stabilize and transport injured patients. The World Health Organization recommends educating layperson first responders as an essential step in the development of Emergency Medical Services systems in LMICs. This systematic review examines trauma educational initiatives for layperson first responders in resource-poor settings. Layperson first-responder training and education program publications were identified using PubMed MEDLINE and Scopus databases. Articles addressing physicians, professional Emergency Medical Services training, or epidemiologic descriptions were excluded. Publications were assessed by independent reviewers, and those included underwent thematic analysis. Thirteen publications met inclusion criteria. Four themes emerged regarding the development of layperson first-responder training programs: (1) An initial needs assessment of a region's existing trauma system of care and laypersons' baseline emergency care knowledge focuses subsequent educational interventions; (2) effective programs adapt to and leverage existing resources; (3) training methods should anticipate participants with low levels of education and literacy; and (4) postimplementation evaluation allows for curriculum improvement. Technology, such as online and remote learning platforms, can be used to operationalize each theme. Successful training programs for layperson first responders in LMICs identify and maximize existing resources are adaptable to learners with little formal education and are responsive to postimplementation evaluation. Educational platforms that leverage technology to deliver content may facilitate first-responder trauma education in underresourced areas. Themes identified can inform the development of trauma systems of care to decrease mortality and physiological severity scores in trauma patients in LMICs. Copyright © 2014 Elsevier Inc.

Systemic trauma.

Substantial theoretical, empirical, and clinical work examines trauma as it relates to individual victims and perpetrators. As trauma professionals, it is necessary to acknowledge facets of institutions, cultures, and communities that contribute to trauma and subsequent outcomes. Systemic trauma-contextual features of environments and institutions that give rise to trauma, maintain it, and impact posttraumatic responses-provides a framework for considering the full range of traumatic phenomena. The current issue of the Journal of Trauma & Dissociation is composed of articles that incorporate systemic approaches to trauma. This perspective extends conceptualizations of trauma to consider the influence of environments such as schools and universities, churches and other religious institutions, the military, workplace settings, hospitals, jails, and prisons; agencies and systems such as police, foster care, immigration, federal assistance, disaster management, and the media; conflicts involving war, torture, terrorism, and refugees; dynamics of racism, sexism, discrimination, bullying, and homophobia; and issues pertaining to conceptualizations, measurement, methodology, teaching, and intervention. Although it may be challenging to expand psychological and psychiatric paradigms of trauma, a systemic trauma perspective is necessary on both scientific and ethical grounds. Furthermore, a systemic trauma perspective reflects current approaches in the fields of global health, nursing, social work, and human rights. Empirical investigations and intervention science informed by this paradigm have the potential to advance scientific inquiry, lower the incidence of a broader range of traumatic experiences, and help to alleviate personal and societal suffering.

Preparing Global Trauma Nurses for Leadership Roles in Global Trauma Systems.

Trauma leads to 5.7 million annual deaths globally, accounting for 25%-33% of global unintentional deaths and 90% of the global trauma burden in low- and middle-income countries. The Lancet Commission on Global Surgery and the World Health Organization assert that emergent and essential surgical capacity building and trauma system improvement are essential to address the global burden of trauma. In response, the Rutgers Global Surgery program, the School of Nursing and Medicine, and the Robert Wood Johnson University Hospital faculty collaborated in the first Interprofessional Models in Global Injury Care and Education Symposium in June 2016. This 2-week symposium combined lectures, high-fidelity simulation, small group workshops, site visits to Level I trauma centers, and a 1-day training course from the Panamerican Trauma Society. The aim was to introduce global trauma nurses to trauma leadership and trauma system development. After completing the symposium, 10 nurses from China, Colombia, Kenya, Puerto Rico, and Uruguay were surveyed. Overall, 88.8% of participants reported high levels of satisfaction with the program and 100% stated being very satisfied with trauma lectures. Symposia, such as that developed and offered by Rutgers University, prepare nurses to address trauma within system-based care and facilitate trauma nursing leadership in their respective countries.

Assuring optimal trauma care: the role of trauma centre accreditation

PubMed Central

Simons, Richard; Kirkpatrick, Andrew

2002-01-01

Optimal care of the injured patient requires the delivery of appropriate, definitive care shortly after injury. Over the last 30 to 40 years, civilian trauma systems and trauma centres have been developed in the United States based on experience gained in military conflicts, particularly in Korea and Vietnam. A similar process is evolving in Canada. National trauma committees in the US and Canada have defined optimal resources to meet the goal of rapid, appropriate care in trauma centres. They have introduced programs (verification or accreditation) to externally audit trauma centre performance based on these guidelines. It is generally accepted that implementing trauma systems results in decreased preventable death and improved survival after trauma. What is less clear is the degree to which each facet of trauma system development contributes to this improvement. The relative importance of national performance guidelines and trauma centre audit as integral steps toward improved outcomes following injury are reviewed. Current Trauma Association of Canada guidelines for trauma centres are presented and the process of trauma centre accreditation is discussed. PMID:12174987

Physician staffed helicopter emergency medical service dispatch via centralised control or directly by crew - case identification rates and effect on the Sydney paediatric trauma system.

Severe paediatric trauma patients benefit from direct transport to dedicated Paediatric Trauma Centres (PTC). Parallel case identification systems utilising paramedics from a centralised dispatch centre versus the crew of a physician staffed Helicopter Emergency Medical Service (HEMS) allowed comparison of the two systems for case identification rates and subsequent timeliness of direct transfer to a PTC. Paediatric trauma patients over a two year period from the Sydney region with an Injury Severity Score (ISS) > 15 were retrospectively identified from a state wide trauma registry. Overall paediatric trauma system performance was assessed by comparisons of the availability of the physician staffed HEMS for patient characteristics, transport mode (direct versus indirect) and the times required for the patient to arrive at the paediatric trauma centre. The proportion of patients transported directly to a PTC was compared between the times that the HEMS service was available versus the time that it was unavailable to determine if the HEMS system altered the rate of direct transport to a PTC. Analysis of variance was used to compare the identifying systems for various patient characteristics when the HEMS was available. Ninety nine cases met the inclusion criteria, 44 when the HEMS system was operational. Patients identified for physician response by the HEMS system were significantly different to those that were not identified with higher median ISS (25 vs 18, p = 0.011), and shorter times to PTC (67 vs 261mins, p = 0.015) and length of intensive care unit stays (2 vs 0 days, p = 0.045). Of the 44 cases, 21 were not identified, 3 were identified by the paramedic system and 20 were identified by the HEMS system, (P < 0.001). Direct transport to a PTC was more likely to occur when the HEMS dispatch system was available (RR 1.81, 95% CI 1.20-2.73). The median time (minutes) to arrival at the PTC was shorter when HEMS available (HEMS available 92, IQR 50-261 versus HEMS unavailable 296, IQR 84-583, P < 0.01). Physician staffed HEMS crew dispatch is significantly more likely to identify cases of severe paediatric trauma and is associated with a greater proportion of transports directly to a PTC and with faster times to arrival.

Florida serves as a model for the study of trauma system performance. Between 2010 and 2104, 5 new trauma centers were opened alongside 20 existing centers. The purpose of this study was to explore the impact of trauma system expansion on system triage performance and trauma center patients' profiles. A statewide data set was queried for all injury-related discharges from adult acute care hospitals using International Classification of Diseases, Ninth Revision (ICD-9) codes for 2010 and 2014. The data set, inclusion criteria, and definitions of high-risk injury were chosen to match those used by the Florida Department of Health in its trauma registry. Hospitals were classified as existing Level I (E1) or Level II (E2) trauma centers and new E2 (N2) centers. Five N2 centers were established 11.6 to 85.3 miles from existing centers. Field and overall trauma system triage of high-risk patients was less accurate with increased overtriage and no change in undertriage. Annual volume at N2 centers increased but did not change at E1 and E2 centers. In 2014, Patients at E1 and E2 centers were slightly older and less severely injured, while those at N2 centers were substantially younger and more severely injured than in 2010. The injured patient-payer mix changed with a decrease in self-pay and commercial patients and an increase in government-sponsored patients at E1 and E2 centers and an increase in self-pay and commercial patients with a decrease in government-sponsored patients at N2 centers. Designation of new trauma centers in a mature system was associated with a change in established trauma center demographics and economics without an improvement in trauma system triage performance. These findings suggest that the health of an entire trauma system network must be considered in the design and implementation of a regional trauma system.

Duplication of Computed Tomography (CT) scanning in trauma patients has been a source of quality waste in healthcare and potential harm for patients. Integrated and regional health systems have been shown to promote opportunities for efficiencies, cost savings and increased safety. This study evaluated traumatically injured patients who required transfer to a Level One Trauma Center (TC) from either within a vertically integrated healthcare system (IN) or from an out-of-network (OON) hospital. We found the rate of repeat CT scanning, radiology costs and total costs for day one of hospitalization to be significantly lower for trauma patients transferred from an IN hospital as compared to those patients transferred from OON hospitals. The inefficiencies and waste often associated with transferred patients can be mitigated and strategies to do so are necessary to reduce costs in the current healthcare environment.

Evaluation of the effectiveness of emergency trauma care systems is complicated by the need to adjust for the widely variable case mix found in trauma patient populations. Several strategies have been advanced to construct the severity indices that can control for these population differences. This article describes a validity and reliability comparison of trauma severity indices developed under three different approaches: 1) use of a multi-attribute utility (MAU) model; 2) an actuarial approach relying on empirical data bases; and 3) an "ad hoc" approach. Seven criteria were identified to serve as standards of comparison for four different indices. The study's findings indicate that the index developed using the MAU theory approach associates most closely with physician judgments of trauma severity. When correlated with a morbidity outcome measure, the MAU-based index shows higher levels of agreement than the other indices. The index development approach based on the principles of MAU theory has several advantages and it appears to be a powerful tool in the creation of effective severity indices.

Multidisciplinary trauma care systems have been shown to improve patient outcomes. Medical care in support of the global war on terror has provided opportunities to refine these systems. We report on the multidisciplinary trauma care system at the Role III Hospital at Kandahar Airfield, Afghanistan. We reviewed the Joint Trauma System Registry, Kandahar database from 1 October 2009 to 31 December 2010 and extracted data regarding patient demographics, clinical variables and outcomes. We also queried the operating room records from 1 January 2009 to 31 December 2010. In the study period of 1 October 2009 to 31 December 2010, 2599 patients presented to the trauma bay, with the most common source of injury being from Improvised Explosive Device (IED) blasts (915), followed by gunshot wounds (GSW) (327). Importantly, 19 patients with triple amputations as a result of injuries from IEDs were seen. 127 patients were massively transfused. The in-hospital mortality was 4.45%. From 1 January 2010 to 31 December 2010, 4106.24 operating room hours were logged to complete 1914 patient cases. The mean number of procedures per case in 2009 was 1.27, compared to 3.11 in 2010. Multinational, multidisciplinary care is required for the large number of severely injured patients seen at Kandahar Airfield. Multidisciplinary trauma care in Kandahar is effective and can be readily employed in combat hospitals in Afghanistan and serve as a model for civilian centres. Published by Elsevier Ltd.

An overview of New Zealand's trauma system.

Patterns of trauma and trauma systems in New Zealand are similar to those in Australia. Both countries have geographical considerations, terrain and distance, that can cause delay to definitive care. There are only 7 hospitals in New Zealand that currently manage major trauma patients, and consequently, trauma patients are often hospitalized some distance from their homes. The prehospital services are provided by one major provider throughout the country, with a high level of volunteers providing these services in the rural areas. New Zealand has a national no-fault accident insurance system, the Accident Compensation Corporation, which funds all trauma-related healthcare from the roadside to rehabilitation. This insurance system provides 24-hour no-fault personal injury insurance coverage. The Accident Compensation Corporation provides bulk funding to hospitals for resources to manage the care of trauma patients. Case managers are assigned for major trauma patients. This national system also has a rehabilitation focus. The actual funds are managed by the hospitals, and this allows hospital staff to provide optimum care for trauma patients. New Zealand works closely with Australia in the development of a national trauma registry, research, and education in trauma care for patients in Australasia (the islands of the southern Pacific Ocean, including Australia, New Zealand, and New Guinea).

This paper discusses mathematical models of expressing severity of injury and probability of survival following trauma and their use in establishing clinical governance of a trauma system. There are five sections: (i) Historical overview of scoring systems—anatomical, physiological and combined systems and the advantages and disadvantages of each. (ii) Definitions used in official statistics—definitions of ‘killed in action’ and other categories and the importance of casualty reporting rates and comparison across conflicts and nationalities. (iii) Current scoring systems and clinical governance—clinical governance of the trauma system in the Defence Medical Services (DMS) by using trauma scoring models to analyse injury and clinical patterns. (iv) Unexpected outcomes—unexpected outcomes focus clinical governance tools. Unexpected survivors signify good practice to be promulgated. Unexpected deaths pick up areas of weakness to be addressed. Seventy-five clinically validated unexpected survivors were identified over 2 years during contemporary combat operations. (v) Future developments—can the trauma scoring methods be improved? Trauma scoring systems use linear approaches and have significant weaknesses. Trauma and its treatment is a complex system. Nonlinear methods need to be investigated to determine whether these will produce a better approach to the analysis of the survival from major trauma. PMID:21149354

Role of Complement on Broken Surfaces After Trauma.

2015-01-01

Activation of both the complement and coagulation cascade after trauma and subsequent local and systemic inflammatory response represent a major scientific and clinical problem. After severe tissue injury and bone fracture, exposure of innate immunity to damaged cells and molecular debris is considered a main trigger of the posttraumatic danger response. However, the effects of cellular fragments (e.g., histones) on complement activation remain enigmatic. Furthermore, direct effects of "broken" bone and cartilage surfaces on the fluid phase response of complement and its interaction with key cells of connective tissues are still unknown. Here, we summarize data suggesting direct and indirect complement activation by extracellular and cellular danger associated molecular patterns. In addition, key complement components and the corresponding receptors (such as C3aR, C5aR) have been detected on "exposed surfaces" of the damaged regions. On a cellular level, multiple effects of complement activation products on osteoblasts, osteoclasts, chondrocytes and mesenchymal stem cells have been found.In conclusion, the complement system may be activated by trauma-altered surfaces and is crucially involved in connective tissue healing and posttraumatic systemic inflammatory response.

The prevalence of posttraumatic stress disorder (PTSD) is high in the armed services, with a rate up to 20%. Multiple studies have associated markers of inflammatory signaling prior to trauma with increased risk of PTSD, suggesting a potential role of the immune system in the development of this psychiatric disorder. One question that arises is if "priming" the immune system before acute trauma alters the stress response and increases enduring effects of trauma. We investigated the time course of inflammatory response to predator stress, a robust stressor that induces enduring PTSD-like behaviors, and the modulation of these effects via prior immune activation with the bacterial endotoxin, lipopolysaccharide (LPS), a Toll-like receptor 4 (TLR4) agonist. Mice exposed to predator stress exhibited decreased pro-/anti-inflammatory balance in the brain 6h after stress, suggesting that predator exposure acutely suppressed the immune system by increasing anti-inflammatory cytokines levels. Acute immune activation with LPS before a single predator stress did not alter the enduring avoidance behavior in stressed mice. Our findings suggest that acute inflammation, at least via TLR4 activation, is not sufficient to increase susceptibility for PTSD-like behaviors in this model. Future studies will examine if chronic inflammation is required to induce similar immune changes to those observed in PTSD patients in this model. Published by Elsevier B.V.

Most people are exposed to at least one traumatic event during the course of their lives, but large numbers of people do not develop posttraumatic stress disorders. Although previous studies have shown that repeated and chronic stress change the brain’s structure and function, few studies have focused on the long-term effects of acute stressful exposure in a nonclinical sample, especially the morphology and functional connectivity changes in brain regions implicated in emotional reactivity and emotion regulation. Forty-one months after the 5/12 Wenchuan earthquake, we investigated the effects of trauma exposure on the structure and functional connectivity of the brains of trauma-exposed healthy individuals compared with healthy controls matched for age, sex, and education. We then used machine-learning algorithms with the brain structural features to distinguish between the two groups at an individual level. In the trauma-exposed healthy individuals, our results showed greater gray matter density in prefrontal-limbic brain systems, including the dorsal anterior cingulate cortex, medial prefrontal cortex, amygdala and hippocampus, than in the controls. Further analysis showed stronger amygdala-hippocampus functional connectivity in the trauma-exposed healthy compared to the controls. Our findings revealed that survival of traumatic experiences, without developing PTSD, was associated with greater gray matter density in the prefrontal-limbic systems related to emotional regulation.

The roles of trauma exposure, rejection sensitivity, and callous-unemotional traits in the aggressive behavior of justice-involved youth: A moderated mediation model.

Research has demonstrated an association between childhood trauma exposure and adolescent aggression. This association may be explained by rejection sensitivity, defined as anger, or anxiety in the anticipation of rejection, which can be a consequence of trauma exposure. Callous-unemotional (CU) traits also are associated with trauma exposure and aggressive behavior; however, research has not yet investigated the interactive roles that rejection sensitivity and CU traits play in the relation between trauma exposure and aggression. Therefore, this study sought to investigate the role of rejection sensitivity in the association between trauma exposure and aggression, and whether this indirect effect was moderated by CU traits. Participants included 380 detained youth (98 girls, 282 boys) who completed self-report measures of trauma exposure, angry, and anxious rejection sensitivity, CU traits, and aggression. Results of moderated mediation demonstrated that the relation between trauma exposure and aggression exhibited an indirect effect through angry rejection sensitivity, but only at moderate or high levels of CU traits. This pattern was not found for anxious rejection sensitivity. Results suggest that interventions aimed to decrease aggressive behavior in traumatized adolescents may benefit from considering how youth respond to rejection, as well as whether youth endorse CU traits, as this may help to limit further involvement in the juvenile justice system after release. © 2018 Wiley Periodicals, Inc.

Among pediatric injury, brain injury is a leading cause of death and disability. To improve outcomes, many developed countries built neurotrauma databank (NTDB) system but there was not established nationwide coverage NTDB until 2009 and there have been few studies on pediatric traumatic head injury (THI) patients in Korea. Therefore, we analyzed epidemiology and outcome from the big data of pediatric THI. We collected data on pediatric patients from 23 university hospitals including 9 regional trauma centers from 2010 to 2014 and analyzed their clinical factors (sex, age, initial Glasgow coma scale, cause and mechanism of head injury, presence of surgery). Among all the 2617 THI patients, total number of pediatric patients was 256. The average age of the subjects was 9.07 (standard deviation±6.3) years old. The male-to female ratio was 1.87 to 1 and male dominance increases with age. The most common cause for trauma were falls and traffic accidents. Age ( p =0.007), surgery ( p <0.001), mechanism of trauma ( p =0.016), subdural hemorrhage (SDH) ( p <0.001), diffuse axonal injury (DAI) ( p <0.001) were statistically significant associated with severe brain injury. Falls were the most common cause of trauma, and age, surgery, mechanism of trauma, SDH, DAI increased with injury severity. There is a critical need for effective fall and traffic accidents prevention strategies for children, and we should give attention to these predicting factors for more effective care.

Distance matters: Effect of geographic trauma system resource organization on fatal motor vehicle collisions.

Trauma systems improve outcome; however, it is unclear how geographic organization of trauma system resources (TSR) affects outcome. Our objective was to evaluate the relationship of fatal motor vehicle collision (MVC) rates and the distance from individual MVC locations to the nearest TSR as a measure of the geographical organization of trauma systems, as well as how theoretical changes in the distribution of TSR may affect fatal MVC rates. All fatal MVC in Pennsylvania 2013-2014 were mapped from the Fatality Analysis Reporting System database. Deaths on scene were excluded. TSR including trauma centers and helicopter bases were mapped. Distance between each fatal MVC and nearest TSR was calculated. The primary outcome was fatal MVC rate per 100 million vehicle miles traveled (VMT). Empiric Bayes kriging and hot spot analysis were performed to evaluate geographic patterns in fatal MVC rates. Association between fatal MVC rate and distance to the nearest TSR was evaluated with linear regression. Spatial lag regression evaluated this association while controlling for MVC and county-level characteristics. We identified 886 fatalities from 863 fatal MVC. Median fatal MVC rate was 0.187 per 100 million VMT. Higher fatal MVC rates and fatality hot spots occur in locations farther from TSR. The fatal MVC rate increased 0.141 per 100 million VMT for every 10 miles farther from the nearest TSR (p < 0.01). When controlling for confounders, the fatal MVC rate increased by 0.089 per 100 million VMT for every 10 miles farther from the nearest TSR (p < 0.01). If two helicopters stationed at trauma centers were relocated into the highest fatality regions, our model predicts a 12.3% relative reduction in the overall MVC fatality rate. Increasing distance to the nearest TSR is associated with increasing fatal MVC rate. The geographic organization of trauma systems may impact outcome, and geospatial analysis can allow data-driven changes to potentially improve outcome.

Besides interleukin (IL)-10, accumulating evidence from in vitro studies has indicated a strong antiinflammatory capacity for IL-13. A prospective clinical study was undertaken to assess the influence of additional brain injury on systemic IL-10 and IL-13 levels as markers for the antiinflammatory state in trauma patients. The course of IL-10 and IL-13 plasma levels from 32 patients with an isolated severe head trauma (SHT), 50 patients with multiple injuries and additional SHT and 39 patients with multiple injuries without SHT was detected using ELISA-technique. Blood samples from 37 healthy blood donors were analysed for control. IL-10 levels were significantly elevated in all 3 injury groups within 3 h after trauma. The lowest initial release was detected in patients with an isolated SHT (Injury severity score; ISS: 18.1 +/- 5.6). No difference could be demonstrated for the IL-10 levels from multiple injured patients with (ISS: 35.3 +/- 9.6) or without additional SHT (ISS: 25.5 +/- 11.7), though there were relevant differences in the ISS. In contrast, the IL-13 plasma levels were not elevated systemically after trauma. IL-10 but not IL-13 is a detectable antiinflammatory marker in trauma patients with or without brain injury and to a minor degree in patients with an isolated SHT.

Standardising trauma monitoring: the development of a minimum dataset for trauma registries in Australia and New Zealand.

Trauma registries are central to the implementation of effective trauma systems. However, differences between trauma registry datasets make comparisons between trauma systems difficult. In 2005, the collaborative Australian and New Zealand National Trauma Registry Consortium began a process to develop a bi-national minimum dataset (BMDS) for use in Australasian trauma registries. This study aims to describe the steps taken in the development and preliminary evaluation of the BMDS. A working party comprising sixteen representatives from across Australasia identified and discussed the collectability and utility of potential BMDS fields. This included evaluating existing national and international trauma registry datasets, as well as reviewing all quality indicators and audit filters in use in Australasian trauma centres. After the working party activities concluded, this process was continued by a number of interested individuals, with broader feedback sought from the Australasian trauma community on a number of occasions. Once the BMDS had reached a suitable stage of development, an email survey was conducted across Australasian trauma centres to assess whether BMDS fields met an ideal minimum standard of field collectability. The BMDS was also compared with three prominent international datasets to assess the extent of dataset overlap. Following this, the BMDS was encapsulated in a data dictionary, which was introduced in late 2010. The finalised BMDS contained 67 data fields. Forty-seven of these fields met a previously published criterion of 80% collectability across respondent trauma institutions; the majority of the remaining fields either could be collected without any change in resources, or could be calculated from other data fields in the BMDS. However, comparability with international registry datasets was poor. Only nine BMDS fields had corresponding, directly comparable fields in all the national and international-level registry datasets evaluated. A draft BMDS has been developed for use in trauma registries across Australia and New Zealand. The email survey provided strong indications of the utility of the fields contained in the BMDS. The BMDS has been adopted as the dataset to be used by an ongoing Australian Trauma Quality Improvement Program. Copyright © 2012 Elsevier Ltd. All rights reserved.

Responses of the pulp, periradicular and soft tissues following trauma to the permanent teeth.

2016-03-01

Trauma to the permanent teeth involves not only the teeth but also the pulp, the periodontal ligament, alveolar bone, gingiva and other associated structures. There are many variations in the types of injuries with varying severity and often a tooth may sustain more than one injury at the same time. In more severe trauma cases, there are many different cellular systems of mineralized hard and unmineralized soft tissues involved, each with varying potential for healing. Furthermore, the responses of the different tissues may be interrelated and dependent on each other. Hence, healing subsequent to dental trauma has long been known to be very complex. Because of this complexity, tissue responses and the consequences following dental trauma have been confusing and puzzling for many clinicians. In this review, the tissue responses are described under the tissue compartments typically involved following dental trauma: the pulp, periradicular and associated soft tissues. The factors involved in the mechanisms of trauma are analysed for their effects on the tissue responses. A thorough understanding of the possible tissue responses is imperative for clinicians to overcome the confusion and manage dental trauma adequately and conservatively in order to minimize the consequences following trauma. © 2016 Australian Dental Association.

Challenges delivering quality care are especially salient during hospital discharge and care transitions. Severely injured patients discharged from a trauma centre will go either home, to rehabilitation or another acute care hospital with complex management needs. This purpose of this study was to explore the experiences of trauma patients and families treated in a regional academic trauma centre to better understand and improve their discharge and care transition experiences. A qualitative study using inductive thematic analysis was conducted between March and October 2016. Telephone interviews were conducted with trauma patients and/or a family member after discharge from the trauma centre. Data collection and analysis were completed inductively and iteratively consistent with a qualitative approach. Twenty-four interviews included 19 patients and 7 family members. Participants' experiences drew attention to discharge and transfer processes that either (1) Fostered quality discharge or (2) Impeded quality discharge. Fostering quality discharge was ward staff preparation efforts; establishing effective care continuity; and, adequate emotional support. Impeding discharge quality was perceived pressure to leave the hospital; imposed transfer decisions; and, sub-optimal communication and coordination around discharge. Patient-provider communication was viewed to be driven by system, rather than patient need. Inter-facility information gaps raised concern about receiving facilities' ability to care for injured patients. The quality of trauma patient discharge and transition experiences is undermined by system- and ward-level processes that compete, rather than align, in producing high quality patient-centred discharge. Local improvement solutions focused on modifiable factors within the trauma centre include patient-oriented discharge education and patient navigation; however, these approaches alone may be insufficient to enhance patient experiences. Trauma patients encounter complex barriers to quality discharge that likely require a comprehensive, multimodal intervention. Copyright © 2017 Elsevier Ltd. All rights reserved.

Trauma care at rural level III trauma centers in a state trauma system.

Helling, Thomas S

2007-02-01

Although much has been written about the benefits of trauma center care, most experiences are urban with large numbers of patients. Little is known about the smaller, rural trauma centers and how they function both independently and as part of a larger trauma system. The state of Missouri has designated three levels of trauma care. The cornerstone of rural trauma care is the state-designated Level III trauma center. These centers are required to have the presence of a trauma team and trauma surgeon but do not require orthopedic or neurosurgical coverage. The purpose of this retrospective study was to determine how Level III trauma centers compared with Level I and Level II centers in the Missouri trauma system and, secondly, how trauma surgeon experience at these centers might shape future educational efforts to optimize rural trauma care. During a 2-year period in 2002 and 2003, the state trauma registry was queried on all trauma admissions for centers in the trauma system. Demographics and patient care outcomes were assessed by level of designation. Trauma admissions to the Level III centers were examined for acuity, severity, and type of injury. The experiences with chest, abdominal, and neurologic trauma were examined in detail. A total of 24,392 patients from 26 trauma centers were examined, including all eight Level III centers. Acuity and severity of injuries were higher at Level I and II centers. A total of 2,910 patients were seen at the 8 Level III centers. Overall deaths were significantly lower at Level III centers (Level I, 4% versus Level II, 4% versus Level III, 2%, p < 0.001). Numbers of patients dying within 24 hours were no different among levels of trauma care (Level I, 37% versus Level II, 30% versus Level III, 32%). Among Level III centers 45 (1.5%) patients were admitted in shock, and 48 (2%) had a Glasgow Coma Scale score <9. Twenty-six patients had a surgical head injury (7 epidural, 19 subdural hematomas). Twenty-eight patients (1%) needed a chest or abdominal operation. There were 15 spleen and 12 liver injuries with an Abbreviated Injury Score of 4 or 5. Level III trauma centers performed as expected in a state trauma system. Acuity and severity were less as was corresponding mortality. There were a paucity of life-threatening head, chest, and abdominal injuries, which provide a challenge to the rural trauma surgeon to maintain necessary skills in management of these critical injuries.

The effect of drugs other than alcohol on severity of trauma remains unclear. Pooled data analyses in previous studies that grouped substances with opposite effects on the central nervous system (CNS) may have masked the influence of substances on injury severity. The aim was to analyze the effect of stimulant, hallucinogenic and depressant drugs other than alcohol on injury severity in trauma patients. The presence of alcohol, stimulant drugs (cocaine, amphetamines and methamphetamines), depressant drugs (benzodiazepines, opiates, methadone and barbiturates) and hallucinogenic drugs (THC and PCP) was analyzed in 1187 patients between 16 and 70 years old admitted to a trauma hospital between November 2012 and June 2015. Injury severity was determined prospectively as the Injury Severity Score. A multivariate analysis was used to quantify the strength of association between exposure to substances and trauma severity, using the presence of alcohol as a stratification variable. Drugs other than alcohol were found in 371 patients (31.3%): 32 (2.7%) stimulants, 186 (15.3%) depressants, 78 (6.6%) hallucinogenics and 75 (5.6%) polydrug use. The presence of CNS depressant substances was associated with increased injury severity only in patients also exposed to alcohol, with an adjusted odds ratio of 4.63 (1.37-15.60) for moderate injuries and 7.83 (2.53-24.21) for severe. CNS depressant drugs had a strong influence on injury severity in patients who screened positive for alcohol consumption. Copyright © 2017 SESPAS. Publicado por Elsevier España, S.L.U.

A review of 452 trauma deaths in Hillsborough County, Florida, in 1984 documented that 23% of non-CNS trauma deaths were preventable and occurred because of inadequate resuscitation or delay in proper surgical care. In late 1988 Hillsborough County organized a County Trauma Agency (HCTA) to coordinate trauma care among prehospital providers and state-designated trauma centers. The purpose of this study was to review county trauma deaths after the inception of the HCTA to determine the frequency of preventable deaths. 504 trauma deaths occurring between October 1989 and April 1991 were reviewed. Through committee review, 10 deaths were deemed preventable; 2 occurred outside the trauma system. Of the 10 deaths, 5 preventable deaths occurred late in severely injured patients. The preventable death rate has decreased to 7.0% with system care. The causes of preventable deaths have changed from delayed or inadequate intervention to postoperative care errors.

The state of US trauma systems: public perceptions versus reality--implications for US response to terrorism and mass casualty events.

Injury has long been identified as the number one killer of Americans under the age of 34, and establishment of regional trauma systems and centers incorporating primary, secondary, and tertiary care and injury-prevention strategies has proved to be a vital element in reducing injury-related sequelae, deaths, and even costs. Despite these facts, trauma system development has not been given priority for funding in many local and state governments and only intermittently at the federal level. Consequently, many of the nation's trauma centers are strapped for funds to provide emergency care to their patients. In response to a 2002 Health Resources and Services Administration (HRSA) report, which identified public support as a key element in the success of trauma system development in states and communities across the United States, a Harris Interactive study was undertaken in the fall of 2004 to determine the public's attitudes, awareness, and knowledge concerning the nature and availability of trauma care and systems of trauma care. Results of the poll were contrasted with current data on the state of US trauma systems to determine the degree of correspondence. Results of the poll indicated that fully 61% of the American public does not know that injury is the leading cause of death for those aged 1 to 34, and most believe that a trauma system is in place in every state. Almost two-thirds of the American public is confident of receiving the best medical care in the event of serious injury and would be seriously concerned if no trauma center were nearby. But only eight states have fully developed trauma systems, and most states have no federal funding or infrastructure in place for managing the aftermath of a natural disaster or terrorist event. These and other objective data reveal the mismatch between public perceptions and reality. Although almost 90% of Americans believe that state trauma systems and hospitals should have a coordinated trauma response, this has not been made a national priority. Trauma systems must be adequately developed and supported to fulfill the public's expectation to receive the best possible care if seriously injured, and to ensure readiness for mass casualty and terrorist incidents.

The so-called off hour effect-that is, increased mortality for patients admitted outside normal working hours-has never been demonstrated in trauma care. However, most of the studies excluded transferred cases. Because these patients are a special challenge for trauma systems, we hypothesised that their processes of care could be more sensitive to the off hour effect. The study design was retrospective, cohort and population based. We compared the mortality of all patients by daytime and night-time admittance to hospitals in an Italian region, with 4.5 million inhabitants, following a major injury in 2011. Logistic regression was used, adjusted for demographics and severity of injury (TMPM-ICD9), and stratified by transfer status. 1940 major trauma cases were included; 105 were acutely transferred. Night-time admission had a significant pejorative effect on mortality in the adjusted analysis (OR=1.49; 95% CI 1.05 to 2.11). This effect was most evident in transferred cases (OR=3.71; 95% CI 1.11 to 12.43). The night-time effect in trauma care was demonstrated for the first time and was maximal in transferred cases. This may explain why it was not found in previous studies where these patients were mostly excluded. Also, the use of population based data-whereby patients not accessing trauma centre care and presumably receiving poorer care were included-may have contributed to the findings.

Unregulated proliferation of trauma centers undermines cost efficiency of population-based injury control.

We evaluated the impact on coverage and regional cost of trauma care produced by the activation of a Level II center with no preceding needs analysis in an established trauma region with a Level I center. Patient deidentified trauma registry data for years 2010, 2011, and 2012 were analyzed to assess the effect on trauma service volume during a period at the midpoint of which the Level II center was activated. Trends for each year were evaluated by patient volume, mechanism, resource use as reflected in a transfer to the intensive care unit (ICU) and ICU stay, patient severity as defined by Injury Severity Score (ISS), and patient injury profile determined by mean body region Abbreviated Injury Scale (AIS) score. Between 2010 and 2011, during which the Level II opened, overall volume at the Level I center dropped by 3.7%, and blunt volume remained unchanged. From 2011 to 2012, overall Level I volume dropped by 9.4%, and blunt injury fell by 14%. Proportions requiring immediate operating room or ICU care did not change. ISS distribution at the Level I center across the years was similar. Head, chest, and abdominal injuries, as assessed by AIS body region, increased slightly in severity and decreased in volume by 25%, 17%, and 18%, respectively. For 2012, the new center publically reported treating 1,100 patients, which, in concert with the Level I decrease, translates to increasing regional trauma center access by 25% while increasing expense of necessary core personnel by 217%. Addition of a second trauma center in a stable region, in which injury incidence was actually decreasing, doubled the cost of personnel, one of the most expensive components of the trauma system and decreased the volume of injuries necessary for training and education. Trauma system expansion must be based on needs assessment, which assures system survival and controls societal cost. Economic & value-based evaluation, level III.

Physician staffed helicopter emergency medical service dispatch via centralised control or directly by crew – case identification rates and effect on the Sydney paediatric trauma system

PubMed Central

2012-01-01

Background Severe paediatric trauma patients benefit from direct transport to dedicated Paediatric Trauma Centres (PTC). Parallel case identification systems utilising paramedics from a centralised dispatch centre versus the crew of a physician staffed Helicopter Emergency Medical Service (HEMS) allowed comparison of the two systems for case identification rates and subsequent timeliness of direct transfer to a PTC. Methods Paediatric trauma patients over a two year period from the Sydney region with an Injury Severity Score (ISS) > 15 were retrospectively identified from a state wide trauma registry. Overall paediatric trauma system performance was assessed by comparisons of the availability of the physician staffed HEMS for patient characteristics, transport mode (direct versus indirect) and the times required for the patient to arrive at the paediatric trauma centre. The proportion of patients transported directly to a PTC was compared between the times that the HEMS service was available versus the time that it was unavailable to determine if the HEMS system altered the rate of direct transport to a PTC. Analysis of variance was used to compare the identifying systems for various patient characteristics when the HEMS was available. Results Ninety nine cases met the inclusion criteria, 44 when the HEMS system was operational. Patients identified for physician response by the HEMS system were significantly different to those that were not identified with higher median ISS (25 vs 18, p = 0.011), and shorter times to PTC (67 vs 261mins, p = 0.015) and length of intensive care unit stays (2 vs 0 days, p = 0.045). Of the 44 cases, 21 were not identified, 3 were identified by the paramedic system and 20 were identified by the HEMS system, (P < 0.001). Direct transport to a PTC was more likely to occur when the HEMS dispatch system was available (RR 1.81, 95% CI 1.20-2.73). The median time (minutes) to arrival at the PTC was shorter when HEMS available (HEMS available 92, IQR 50-261 versus HEMS unavailable 296, IQR 84-583, P < 0.01). Conclusions Physician staffed HEMS crew dispatch is significantly more likely to identify cases of severe paediatric trauma and is associated with a greater proportion of transports directly to a PTC and with faster times to arrival.

Attenuated activity of stress-regulating systems has consistently been reported in boys with conduct problems. Results in studies of girls are inconsistent, which may result from the high prevalence of comorbid post-trauma symptoms. Therefore, the aim of the present study is to investigate post-trauma symptoms as a potential mediator in the relation between stress-regulation systems functioning and conduct problems in female adolescents. The sample consisted of 78 female adolescents (mean age 15.4; SD 1.1) admitted to a closed treatment institution. The diagnosis of disruptive behaviour disorder (DBD) was assessed by a structured interview-the diagnostic interview schedule for children version IV (DISC-IV). To assess post-trauma symptoms and externalizing behaviour problems, self-report questionnaires, youth self report (YSR) and the trauma symptom checklist for Children (TSCC) were used. The cortisol awakenings response (CAR) measured hypothalamic-pituitary-adrenal (HPA) axis activity, whereas autonomous nervous system (ANS) activity was assessed by heart rate (HR), pre-ejection period (PEP) and respiratory sinus arrhythmia (RSA). Independent t-tests were used to compare girls with and without DBD, while path analyses tested for the mediating role of post- trauma symptoms in the relation between stress regulating systems and externalizing behaviour. Females with DBD (n = 37) reported significantly higher rates of post-trauma symptoms and externalizing behaviour problems than girls without DBD (n = 39). Path analysis found no relation between CAR and externalizing behaviour problems. With regard to ANS activity, positive direct effects on externalizing behaviour problems were present for HR (standardized β = 0.306, p = 0.020) and PEP (standardized β = -0.323, p = 0.031), though not for RSA. Furthermore, no relation-whether direct or indirect-could be determined from post-trauma symptoms. Present findings demonstrate that the neurobiological characteristics of female externalizing behaviour differ from males, since girls showed heightened instead of attenuated ANS activity. While the prevalence of post-trauma symptoms was high in girls with DBD, it did not mediate the relation between stress parameters and externalizing behaviour. Clinical implications and future directions are discussed.

Literature has shown there are significant differences between administrative databases and clinical registry data. Our objective was to compare the identification of trauma patients using All Patient Refined Diagnosis Related Groups (APR-DRG) as compared to the Trauma Registry and estimate the effects of those discrepancies on utilization. Admitted pediatric patients from 1/2012-12/2013 were abstracted from the trauma registry. The patients were linked to corresponding administrative data using the Pediatric Health Information System database at a single children's hospital. APR-DRGs referencing trauma were used to identify trauma patients. We compared variables related to utilization and diagnosis to determine the level of agreement between the two datasets. There were 1942 trauma registry patients and 980 administrative records identified with trauma-specific APR-DRG during the study period. Forty-two percent (816/1942) of registry records had an associated trauma-specific APR-DRG; 69% of registry patients requiring ICU care had trauma APR-DRGs; 73% of registry patients with head injuries had trauma APR-DRGs. Only 21% of registry patients requiring surgical management had associated trauma APR-DRGs, and 12.5% of simple fractures had associated trauma APR-DRGs. APR-DRGs appeared to only capture a fraction of the entire trauma population and it tends to be the more severely ill patients. As a result, the administrative data was not able to accurately answer hospital or operating room utilization as well as specific information on diagnosis categories regarding trauma patients. APR-DRG administrative data should not be used as the only data source for evaluating the needs of a trauma program. Copyright © 2016 Elsevier Ltd. All rights reserved.

Trimodal distribution of trauma deaths, described more than 20 years ago, is still widely taught in the design of trauma systems. The purpose of this study was to examine the applicability of this trimodal distribution in a modern trauma system. A study of trauma registry and emergency medical services records of trauma deaths in the County of Los Angeles was conducted over a 3-year period. The times from injury to death were analyzed according to mechanism of injury and body area (head, chest, abdomen, extremities) with severe trauma (abbreviated injury score [AIS] >/= 4). During the study period there were 4,151 trauma deaths. Penetrating trauma accounted for 50.0% of these deaths. The most commonly injured body area with critical trauma (AIS >/= 4) was the head (32.0%), followed by chest (20.8%), abdomen (11.5%), and extremities (1.8%). Time from injury to death was available in 2,944 of these trauma deaths. Overall, there were two distinct peaks of deaths: the first peak (50.2% of deaths) occurred within the first hour of injury. The second peak occurred 1 to 6 hours after admission (18.3% of deaths). Only 7.6% of deaths were late (>1 week), during the third peak of the classic trimodal distribution. Temporal distribution of deaths in penetrating trauma was very different from blunt trauma and did not follow the classic trimodal distribution. Other significant independent factors associated with time of death were chest AIS and head AIS. Temporal distribution of deaths as a result of severe head trauma did not follow any pattern and did not resemble classic trimodal distribution at all. The classic "trimodal" distribution of deaths does not apply in our trauma system. Temporal distribution of deaths is influenced by the mechanism of injury, age of the patient, and body area with severe trauma. Knowledge of the time of distribution of deaths might help in allocating trauma resources and focusing research effort.

Trauma-informed juvenile justice systems: A systematic review of definitions and core components.

The U.S. Department of Justice has called for the creation of trauma-informed juvenile justice systems in order to combat the negative impact of trauma on youth offenders and frontline staff. Definitions of trauma-informed care have been proposed for various service systems, yet there is not currently a widely accepted definition for juvenile justice. The current systematic review examined published definitions of a trauma-informed juvenile justice system in an effort to identify the most commonly named core elements and specific interventions or policies. A systematic literature search was conducted in 10 databases to identify publications that defined trauma-informed care or recommended specific practices or policies for the juvenile justice system. We reviewed 950 unique records, of which 10 met criteria for inclusion. The 10 publications included 71 different recommended interventions or policies that reflected 10 core domains of trauma-informed practice. We found 8 specific practice or policy recommendations with relative consensus, including staff training on trauma and trauma-specific treatment, while most recommendations were included in 2 or less definitions. The extant literature offers relative consensus around the core domains of a trauma-informed juvenile justice system, but much less agreement on the specific practices and policies. A logical next step is a review of the empirical research to determine which practices or policies produce positive impacts on outcomes for youth, staff, and the broader agency environment, which will help refine the core definitional elements that comprise a unified theory of trauma-informed practice for juvenile justice.

Trauma is a leading cause of death and disability worldwide. Patients presenting with severe trauma and burns benefit from specifically trained multidisciplinary teams. Regional trauma systems have shown improved outcomes for trauma patients. The aim of this study is to determine whether the development of major trauma systems have improved the management of patients with major burns. A retrospective study was performed over a four-year period reviewing all major burns in adults and children received at a regional burns centre in the UK before and after the implementation of the regional trauma systems and major trauma centres (MTC). Comparisons were drawn between three areas: (1) Patients presenting before the introduction of MTC and after the introduction of MTC. (2) Patients referred from MTC and non-MTC within the region, following the introduction of MTC. (3) Patients referred using the urban trauma protocol and the rural trauma protocol. Following the introduction of regional trauma systems and major trauma centres (MTC), isolated burn patients seen at our regional burns centre did not show any significant improvement in transfer times, admission resuscitation parameters, organ dysfunction or survival when referred from a MTC compared to a non-MTC emergency department. There was also no significant difference in survival when comparing referrals from all hospitals pre and post establishment of the major trauma network. No significant outcome benefit was demonstrated for burns patients referred via MTCs compared to non-MTCs. We suggest further research is needed to ascertain whether burns patients benefit from prolonged transfer times to a MTC compared to those seen at their local hospitals prior to transfer to a regional burns unit for further specialist care.

The optimal timing for emergency surgical interventions and implementation of protocols for trauma surgery is insufficient in the literature. The Groote Schuur emergency surgery triage (GSEST) system, based on Cape Triaging Score (CTS), is followed at Groote Schuur Hospital (GSH) for triaging emergency surgical cases including trauma cases. The study aimed to look at the effect of delay in surgery after scheduling based on the GSEST system has an impact on outcome in terms of postoperative complications and death. Prospective audit of patients presenting to GSH trauma center following penetrating or blunt chest, abdominal, neck and peripheral vascular trauma who underwent surgery over a 4-month period was performed. Post-operative complications were graded according to Clavien-Dindo classification of surgical complications. One-hundred six patients underwent surgery during the study period. One-hundred two (96.2%) cases were related to penetrating trauma. Stab wounds comprised 71 (67%) and gunshot wounds (GSW) 31 (29.2%) cases. Of the 106 cases, 6, 47, 40, and 13 patients were booked as red, orange, yellow, and green, respectively. The median delay for green, yellow, and orange cases was within the expected time. The red patients took unexpectedly longer (median delay 48 min, IQR 35-60 min). Thirty-one (29.3%) patients developed postoperative complications. Among the booked red, orange, yellow, and green cases, postoperative complications developed in 3, 18, 9, and 1 cases, respectively. Only two (1.9%) postoperative deaths were documented during the study period. There was no statistically significant association between operative triage and post-operative complications ( p  = 0.074). Surgical case categorization has been shown to be useful in prioritizing emergency trauma surgical cases in a resource constraint high-volume trauma center.

Male sexual trauma is understudied, leaving much to be known about the unique mental health needs of male survivors. This study examined veteran men's perceptions of the effects of military sexual trauma. Military sexual trauma was defined as physically forced, verbally coerced, or substance-incapacitated acts experienced during military service. Interviews were conducted with 21 male veterans who reported experiencing military sexual trauma. Data were drawn together using a grounded theory methodology. Three categories emerged from data analysis, including (a) types of military sexual trauma (being touched in a sexual way against their will [N = 18]; sexual remarks directed at them [N = 15]; being physically forced to have sex [N = 13]); (b) negative life effects (difficulty trusting others [N = 18]; fear of abandonment [N = 17]; substance use [N = 13]; fear of interpersonal violence [N = 12]; conduct and vocational problems [N = 11]; irritability/aggression [N = 8]; insecurity about sexual performance [N = 8]; difficulty managing anger [N = 8]); and (c) posttraumatic growth (N = 15). Results from this study suggest sexual trauma in the military context may affect systems of self-organization, specifically problems in affective, self-concept, and relational domains, similar to symptoms of those who have experienced prolonged traumatic stressors. This model can be used by clinicians to select treatments that specifically target these symptoms and promote posttraumatic growth. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Time to definitive care following injury is important to the outcomes of trauma patients. Prehospital trauma care is provided based on policies developed by individual trauma systems and is an important component of the care of injured patients. Given a paucity of systems-level trauma research, considerable variability exists in prehospital care policies across trauma systems, potentially affecting patient outcomes. To evaluate whether private vehicle prehospital transport confers a survival advantage vs ground emergency medical services (EMS) transport following penetrating injuries in urban trauma systems. Retrospective cohort study of data included in the National Trauma Data Bank from January 1, 2010, through December 31, 2012, comprising 298 level 1 and level 2 trauma centers that contribute data to the National Trauma Data Bank that are located within the 100 most populous metropolitan areas in the United States. Of 2 329 446 patients assessed for eligibility, 103 029 were included in this study. All patients were 16 years or older, had a gunshot wound or stab wound, and were transported by ground EMS or private vehicle. In-hospital mortality. Of the 2 329 446 records assessed for eligibility, 103 029 individuals at 298 urban level 1 and level 2 trauma centers were included in the analysis. The study population was predominantly male (87.6%), with a mean age of 32.3 years. Among those included, 47.9% were black, 26.3% were white, and 18.4% were Hispanic. Following risk adjustment, individuals with penetrating injuries transported by private vehicle were less likely to die than patients transported by ground EMS (odds ratio [OR], 0.38; 95% CI, 0.31-0.47). This association remained statistically significant on stratified analysis of the gunshot wound (OR,  0.45; 95% CI, 0.36-0.56) and stab wound (OR,  0.32; 95% CI, 0.20-0.52) subgroups. Private vehicle transport is associated with a significantly lower likelihood of death when compared with ground EMS transport for individuals with gunshot wounds and stab wounds in urban US trauma systems. System-level evidence such as this can be a valuable tool for those responsible for developing and implementing policies at the trauma system level.

Trauma is a leading cause of death worldwide and a major health problem of the modern society. Trauma systems are considered the gold standard of managing patients with trauma. An integral part of any trauma system is a trauma registry. In Europe, and particularly in Greece, trauma registries and systems are in an embryonic stage. In this study, we present an attempt to record trauma in Greece. The Hellenic Society of Trauma and Emergency Surgery invited all the official representatives of the society throughout the country to participate in the study. In succeeding meetings of the representatives, the reporting form was developed and the inclusion criteria were defined meticulously. Inclusion criteria were defined as patients with trauma requiring admission, transfer to a higher level center, or arrived dead or died in the emergency department of the reporting hospital. All reports were accumulated by the Hellenic Trauma society, imported in an electronic database, and analyzed. Thirty-two hospitals receiving patients with trauma participated in the country, representing 40% of the country's healthcare facilities and serving 40% of the country's population. In 12 months time, (October 2005 to September 2006), 8,862 patients were included in the study. Of them, 66.9% were men and 31.3% were women. The compilation rate of the reporting forms was surprisingly high, considering that the final reporting form included 150 data points and that there were no independent personnel in charge of filling the forms. Trauma registries are feasible even in health care systems where funding of medical research is sparse.

Background The decision-making processes used for out-of-hospital trauma triage and hospital selection in regionalized trauma systems remain poorly understood. The objective of this study was to understand the process of field triage decision-making in an established trauma system. Methods We used a mixed methods approach, including EMS records to quantify triage decisions and reasons for hospital selection in a population-based, injury cohort (2006 - 2008), plus a focused ethnography to understand EMS cognitive reasoning in making triage decisions. The study included 10 EMS agencies providing service to a 4-county regional trauma system with 3 trauma centers and 13 non-trauma hospitals. For qualitative analyses, we conducted field observation and interviews with 35 EMS field providers and a round-table discussion with 40 EMS management personnel to generate an empirical model of out-of-hospital decision making in trauma triage. Results 64,190 injured patients were evaluated by EMS, of whom 56,444 (88.0%) were transported to acute care hospitals and 9,637 (17.1% of transports) were field trauma activations. For non-trauma activations, patient/family preference and proximity accounted for 78% of destination decisions. EMS provider judgment was cited in 36% of field trauma activations and was the sole criterion in 23% of trauma patients. The empirical model demonstrated that trauma triage is driven primarily by EMS provider “gut feeling” (judgment) and relies heavily on provider experience, mechanism of injury, and early visual cues at the scene. Conclusions Provider cognitive reasoning for field trauma triage is more heuristic than algorithmic and driven primarily by provider judgment, rather than specific triage criteria. PMID:21817971

Examination of the epidemiology and timing of trauma deaths has been deemed a useful method to evaluate the quality of trauma care. The purpose of this study was to evaluate the quality of trauma care in a regional trauma system and in a university hospital in Brazil by comparing the timing of deaths in the studied prehospital and in-hospital settings to those published for trauma systems in other areas. We analyzed the National Health Minister's System of Deaths Information for the prehospital mortality and we retrospectively collected the demographics, timelines, and trauma severity scores of all in-hospital patients who died after admission through the Emergency Unit of Hospital das Clinicas de Ribeirao Preto between 2000 and 2001. During the study period, there were 787 trauma fatalities in the city: 448 (56.9%) died in the prehospital setting and 339 (43.1%) died after being admitted to a medical facility. In 2 years, 238 trauma deaths occurred in the studied hospital, and we found a complete clinical set of data for 224 of these patients. The majority of deaths in the prehospital setting were caused by penetrating injuries (66.7%), whereas in-hospital mortality was mainly because of blunt traumas (59.1%). The largest number of in-hospital deaths occurred beyond 72 hours of stay (107 patients-47%). The region studied showed some deficiencies in prehospital and in-hospitals settings, in particular in the critical care and short-term follow-up of trauma patients when compared with the literature. Particularly, the late mortality may be related to training and human resources deficiency. Based on the timeline of trauma deaths, we can suggest that the studied region needs improvements in the prehospital trauma system and in hospital critical care.

Nurturing Environments for Boys and Men of Color with Trauma Exposure.

Boys and men of color are exposed to traumatic experiences at significantly higher rates than are other demographic groups. To understand and address the mental and behavioral health effects of trauma, including violent incidents, on this population, we review the literature showing the context for, outcomes of, and potential responses to trauma exposure. We present the existing research about the unique challenges and associated negative outcomes for boys and men of color, as well as identify the gaps in the literature. We present the potential nurturing responses by systems such as schools, law enforcement, and communities to trauma-exposed boys and men of color, and we describe evidence-based programs and practices that directly address trauma. Finally, we argue that, rather than using a deficit model, a model of optimal development can be used to understand how to support and protect boys and men of color through nurturing environments.

Development and validation of a brief trauma screening measure for children: The Child Trauma Screen.

Childhood exposure to trauma, including violence and abuse, is a major public health concern that has resulted in increased efforts to promote trauma-informed child-serving systems. Trauma screening is an important component of such trauma-informed systems, yet widespread use of trauma screening is rare in part due to the lack of brief, validated trauma screening measures for children. We describe development and validation of the Child Trauma Screen (CTS), a 10-item screening measure of trauma exposure and posttraumatic stress disorder (PTSD) symptoms for children consistent with the DSM-5 definition of PTSD. Study 1 describes measure development incorporating analysis to derive items based on existing measures from 1,065 children and caregivers together with stakeholder input to finalize item selection. Study 2 describes validation of the CTS with a clinical sample of 74 children and their caregivers. Results support the CTS as an empirically derived, reliable measure to screen children for trauma exposure and PTSD symptoms with strong convergent, divergent, and criterion validity. The CTS is a promising measure for rapidly and reliably screening children for trauma exposure and PTSD symptoms. Future research is needed to confirm validation and to examine feasibility and utility of its use across various child-serving systems. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Objective The aim of the present study was to estimate the cost-effectiveness of trauma service funding enhancements at an inner city major trauma centre. Methods The present study was a cost-effectiveness analysis using retrospective trauma registry data of all major trauma patients (injury severity score >15) presenting after road trauma between 2001 and 2012. The primary outcome was cost per life year gained associated with the intervention period (2007-12) compared with the pre-intervention period (2001-06). Incremental costs were represented by all trauma-related funding enhancements undertaken between 2007 and 2010. Risk adjustment for years of life lost was conducted using zero-inflated negative binomial regression modelling. All costs were expressed in 2012 Australian dollar values. Results In all, 876 patients were identified during the study period. The incremental cost of trauma enhancements between 2007 and 2012 totalled $7.91million, of which $2.86million (36%) was attributable to road trauma patients. After adjustment for important covariates, the odds of in-hospital mortality reduced by around half (adjusted odds ratio (OR) 0.48; 95% confidence interval (CI) 0.27, 0.82; P=0.01). The incremental cost-effectiveness ratio was A$7600 per life year gained (95% CI A$5524, $19333). Conclusion Trauma service funding enhancements that enabled a quality improvement program at a single major trauma centre were found to be cost-effective based on current international and Australian standards. What is known about this topic? Trauma quality improvement programs have been implemented across most designated trauma hospitals in an effort to improve hospital care processes and outcomes for injured patients. These involve a combination of education and training, the use of audit and key performance indicators. What does this paper add? A trauma quality improvement program initiated at an Australian Major Trauma Centre was found to be cost-effective over 12 years with respect to years of life saved in road trauma patients. What are the implications for practitioners? The results suggest that adequate resourcing of trauma centres to enable quality improvement programs may be a cost-effective measure to reduce in-hospital mortality following road trauma.

We describe a case story with a drowned, hypothermic trauma patient treated with an automatic mechanical chest compression device during helicopter transportation to a trauma center. After falling from a 25 meter high bridge into 2 °C water, she was rescued lifeless 17 minutes later. Advanced life support was initiated. During transport by a rescue helicopter, chest compressions were effectively provided by Lund University Cardiopulmonary Assist System (LUCAS). Upon arrival to a trauma centre approx. 60 minutes later, the patient was treated with extracorporal circulation and rewarmed. She was eventually discharged to her home with minor loss of cerebral function.

Monotherapy of consequences of craniocerebral trauma with pyrazidol (1 mg/kg) produced an anxiolytic effect in animals highly resistant to hypoxia and activating effect on low resistant animals. Treatment with bemitil in a dose of 25 mg/kg produced a cerebroprotective effect and normalized individual behavioral characteristics, parameters of energy metabolism, and state of the antioxidant system in the brain of highly and low resistant rats. The effect of bemitil was most pronounced in highly resistant animals. During combined treatment, pyrazidol and bemitil had an additive effect in animals of both groups. They normalized behavioral reactions and prevented the development of metabolic disturbances in the brain.

Introduction Trauma remains the primary cause of death in individuals under 40 years of age in Canada. In Quebec, the Trauma Care Continuum (TCC) has been demonstrated to be effective in decreasing the mortality rate among trauma victims. Although rural citizens are at greater risk for trauma and trauma death, no empirical data concerning the effectiveness of the TCC for the rural population in Quebec are available. The emergency departments (EDs) are important safety nets for rural citizens. However, our data indicate that access to diagnostic support services, such as intensive care units and CT is limited in rural areas. The objectives are to (1) draw a portrait of trauma services in rural EDs; (2) explore geographical variations in trauma care in Quebec; (3) identify adaptable factors that could reduce variation; and (4) establish consensus solutions for improving the quality of care. Methods and analysis The study will take place from November 2015 to November 2018. A mixed methodology (qualitative and quantitative) will be used. We will include data (2009–2013) from all trauma victims treated in the 26 rural EDs and tertiary/secondary care centres in Quebec. To meet objectives 1 and 2, data will be gathered from the Ministry's Database of the Quebec Trauma Registry Information System. For objectives 3 and 4, the project will use the Delphi method to develop consensus solutions for improving the quality of trauma care in rural areas. Data will be analysed using a Poisson regression to compare mortality rate during hospital stay or death on ED arrival (objectives 1 and 2). Average scores and 95% CI will be calculated for the Delphi questionnaire (objectives 3 and 4). Ethics and dissemination This protocol has been approved by CSSS Alphonse-Desjardins research ethics committee (Project MP-HDL-2016-003). The results will be published in peer-reviewed journals.

2017-06-15

According to several studies, the onset of the Borderline Personality Disorder (BPD) depends on the combination between genetic and environmental factors (GxE), in particular between biological vulnerabilities and the exposure to traumatic experiences during childhood. We have searched for studies reporting possible alterations in several biological processes and brain morphological features in relation to childhood trauma experiences and to BPD. We have also looked for epigenetic mechanisms as they could be mediators of the effects of childhood trauma in BPD vulnerability. We prove the role of alterations in Hypothalamic-Pituitary-Adrenal (HPA) axis, in neurotrasmission, in the endogenous opioid system and in neuroplasticity in the childhood trauma-associated vulnerability to develop BPD; we also confirm the presence of morphological changes in several BPD brain areas and in particular in those involved in stress response. Not so many studies are available on epigenetic changes in BPD patients, although these mechanisms are widely investigated in relation to stress-related disorders. A better comprehension of the biological and epigenetic mechanisms, affected by childhood trauma and altered in BPD patients, could allow to identify "at high risk" subjects and to prevent or minimize the development of the disease later in life.

Blunt thoracic injury often leads to pulmonary contusion and the development of acute respiratory distress syndrome, which carries a high risk of morbidity and mortality, originating from the local and systemic inflammatory states. This study aimed to investigate the local and systemic antiinflammatory effects of levosimendan in rat models of blunt chest trauma. A total of 32 Wistar albino rats were randomly assigned to one of the following four groups: control, sham, low-dose levosimendan (LDL) (5 µg/kg loading dose for 10 min and 0.05 µg/kg/min intravenous infusion), and high-dose levosimendan (HDL) (10 µg/kg loading dose for 10 min and 0.1 µg/kg/min intravenous infusion). Blunt chest trauma was induced, and after 6 h, the contused pulmonary tissues were histopathologically and immunohistopathologically evaluated, serum TNF-α, IL-1ß, IL-6, and NO levels were biochemically evaluated. The mean arterial pressure was low throughout the experiment in the LDL and HDL groups, with no statistically difference between the groups. Levosimendan reduced the alveolar congestion and hemorrhage, which developed after inducing trauma. Neutrophil infiltration to the damaged pulmonary tissue was also reduced in both the LDL and HDL groups. In rats in which pulmonary contusion (PC) was observed, increased activation of nuclear factor kappa B was observed in the pulmonary tissue, and levosimendan did not reduce this activation. Both high and low doses of levosimendan reduced serum IL-1ß levels, and high doses of levosimendan reduced IL-6 and NO levels. TNF-α levels were not reduced. In conclusion, the results showed that in a rat model of PC, the experimental agent levosimendan could reduce neutrophil cell infiltration to damaged pulmonary tissues and the systemic expressions of some cytokines (IL-1ß, IL-6, and NO), thereby partially reducing and/or correcting pulmonary damage. Systemic inflammatory response that occurs after trauma could also be reduced.

The introduction of diagnosis-related groups (DRG) in Germany comprises the risk of a non-cost-effective reimbursement in complex medical treatments. The aim of this study was to compare the reimbursement between the DRG system and the system of hospital per diem charge in effect until now. The G-DRG (Version 2004) reimbursement was calculated for 1,030 polytrauma patients (average ISS 26.4) treated at the BGU Murnau from 2000 to 2004, using a base value of 2900 euros, and compared to the reimbursement of hospital per diem charge. Just half of all polytrauma patients are classified as a polytrauma according to the DRG (18.7%) or as requiring artificial respiration based on the DRG (29.1%). The average G-DRG reimbursement was 27,157 euros vs 36,387 euros (74.6%). Patients with minor trauma, increasing age, high GCS, ICU stay without artificial respiration, trauma of the upper extremity and patients who survived show the greatest discrepancy. A revision of the G-DRG definition of polytrauma is necessary to ensure adequate reimbursement for management of patients with multiple injuries. The severity of a trauma has to be considered in the DRG system.

Trauma is a major cause of 10% death in the worldwide and is considered as a global concern. This problem has made healthcare policy makers and managers to adopt a basic strategy in this context. Trauma registry has an important and basic role in decreasing the mortality and the disabilities due to injuries resulted from trauma. Today, different software are designed for trauma registry. Evaluation of this software improves management, increases efficiency and effectiveness of these systems. Therefore, the aim of this study is to present an evaluation model for trauma registry software. The present study is an applied research. In this study, general and specific criteria of trauma registry software were identified by reviewing literature including books, articles, scientific documents, valid websites and related software in this domain. According to general and specific criteria and related software, a model for evaluating trauma registry software was proposed. Based on the proposed model, a checklist designed and its validity and reliability evaluated. Mentioned model by using of the Delphi technique presented to 12 experts and specialists. To analyze the results, an agreed coefficient of %75 was determined in order to apply changes. Finally, when the model was approved by the experts and professionals, the final version of the evaluation model for the trauma registry software was presented. For evaluating of criteria of trauma registry software, two groups were presented: 1- General criteria, 2- Specific criteria. General criteria of trauma registry software were classified into four main categories including: 1- usability, 2- security, 3- maintainability, and 4-interoperability. Specific criteria were divided into four main categories including: 1- data submission and entry, 2- reporting, 3- quality control, 4- decision and research support. The presented model in this research has introduced important general and specific criteria of trauma registry software and sub criteria related to each main criteria separately. This model was validated by experts in this field. Therefore, this model can be used as a comprehensive model and a standard evaluation tool for measuring efficiency and effectiveness and performance improvement of trauma registry software.

Improving the delivery of efficient and effective surgical care in rural South Africa is a mammoth task bedevilled by conflict between the stakeholders, who include rural doctors, surgeons, ancillary staff, researchers, educators and administrators. Management training is not part of most medical school curricula, yet as they progress in their careers, many clinicians are required to manage a health system and find the shift from caring for individual patients to managing a complex system difficult. Conflict arises when management-type interventions are imposed in a top-down manner on surgical staff suspicious of an unfamiliar field of study. Another area of conflict concerns the place of surgical research. Researchers are often accused of not being sufficiently focused on or concerned about the tasks of service delivery. This article provides an overview of management theory and describes a comprehensive management structure that integrates a model for health systems with a strategic planning process, strategic planning tools and appropriate quality metrics, and shows how the Pietermaritzburg Metropolitan Trauma Service in KwaZulu-Natal Province, South Africa, successfully used this structure to facilitate and contextualise a diverse number of quality improvement programmes and research initiatives in the realm of rural acute surgery and trauma. We have found this structure to be useful, and hope that it may be applied to other acute healthcare systems.

The metabolic syndrome and associated fatty liver disease are thought to contribute to poor outcomes in trauma patients. Experimentally, obesity compromises liver blood flow. We sought to correlate the effect of obesity, injury severity, and liver dysfunction with trauma outcomes. We hypothesized that obesity-related liver dysfunction could be mitigated with the novel technique of adjunctive direct peritoneal resuscitation (DPR). This study has clinical and experimental arms. The clinical study was a case-controlled retrospective analysis of ICU trauma patients (n = 72 obese, n = 187 nonobese). The experimental study was a hemorrhagic shock model in obese rats to assess the effect of DPR on liver blood flow, liver function, and inflammatory mediators. In trauma patients, univariate and multivariate analyses demonstrated increasing mortality (p < 0.05), septic complications (p < 0.05), liver dysfunction (p < 0.001), and renal impairment (p < 0.05) with increasing body mass index and injury severity score. Obesity in rats impairs liver blood flow, liver function, renal function, and inflammation (interleukin [IL]-1β, IL-6, high mobility group protein B1[HMGB-1]). The addition of DPR to shock resuscitation restores liver blood flow, improves organ function, and reverses the systemic proinflammatory response. Our clinical review substantiates that obesity worsens trauma outcomes regardless of injury severity. Obesity-related liver and renal dysfunction is aggravated by injury severity. In an obese rat model of resuscitated hemorrhagic shock, the addition of DPR abrogates trauma-induced liver, renal, and inflammatory responses. We conclude that the addition of DPR to the clinical resuscitation regimen will benefit the obese trauma patient. Published by Elsevier Inc.

Trauma remains a leading cause of death and disability in the world, and trauma systems decrease mortality from trauma. We developed the Global Trauma System Evaluation Tool (G-TSET) specifically for use in low- and middle-income countries (LMICs). The Sudan People's Liberation Army (SPLA) in the Republic of South Sudan (RSS) desires a military trauma system (MTS) which allowed us to pilot the G-TSET. The G-TSET was developed by modifying key components of a trauma system applicable to LMICs. We partnered with the SPLA Medical Corps using clinical collaboration, direct observation, and discussion groups. Benchmarks and indicators were scored with 5 indicating "full capability" and 1 meaning "not present" and were used to develop a SPLA MTS plan. The overall MTS score was 1.15 indicating an urgent need for system development. The assessment highlighted the need for SPLA Command support. Battlefield care, transport to a trauma facility, and inter-facility communication were identified for improvement. After essential battlefield care, consisting primarily of bandaging and splinting, transport times for injured SPLA soldiers were 12h to 3 days by truck. Based on our findings, we collaborated with SPLA medical leadership to develop a plan to develop a formal MTS. We piloted a novel trauma system assessment tool for the MTS in the RSS. Qualitatively, we identified gaps in the MTS and provided the medical leadership with a plan for improvement. We anticipate a short-term follow-up to quantify improvement, and we seek to validate this tool for use in other countries. Published by Elsevier Ltd.

Objective: The objective of this study was to investigate the effect of American College of Surgeons (ACS) trauma center designation and trauma volume on outcome in patients with specific severe injuries. Background: Trauma centers are designated by the ACS into different levels on the basis of resources, trauma volume, and educational and research commitment. The criteria for trauma center designation are arbitrary and have never been validated. Methods: The National Trauma Data Bank study, which included patients >14 years of age and had injury severity score (ISS) >15, were alive on admission and had at least one of the following severe injuries: aortic, vena cava, iliac vessels, cardiac, grade IV/V liver injuries, quadriplegia, or complex pelvic fractures. Outcomes (mortality, intensive care unit stay, and severe disability at discharge) were compared among level I and II trauma centers and between centers within the same level designation but different volumes of severe trauma (<240 vs ≥240 trauma admissions with ISS >15 per year). The outcomes were adjusted for age (<65 ≥65), gender, mechanism of injury, hypotension on admission, and ISS (≤25 and >25). Results: A total of 12,254 patients met the inclusion criteria. Overall, level I centers had significantly lower mortality (25.3% vs 29.3%; adjusted odds ratio [OR], 0.81; 95% confidence interval [CI], 0.71–0.94; P = 0.004) and significantly lower severe disability at discharge (20.3% vs 33.8%, adjusted OR, 0.55; 95% CI, 0.44–0.69; P < 0.001) than level II centers. Subgroup analysis showed that cardiovascular injuries (N = 2004) and grades IV–V liver injuries (N = 1415) had a significantly better survival in level I than level II trauma centers (adjusted P = 0.017 and 0.023, respectively). Overall, there was a significantly better functional outcome in level I centers (adjusted P < 0.001). Subgroup analysis showed level I centers had significantly better functional outcomes in complex pelvic fractures (P < 0.001) and a trend toward better outcomes in the rest of the subgroups. The volume of trauma admissions with ISS >15 (<240 vs ≥240 cases per year) had no effect on outcome in either level I or II centers. Conclusions: Level I trauma centers have better outcomes than lower-level centers in patients with specific injuries associated with high mortality and poor functional outcomes. The volume of major trauma admissions does not influence outcome in either level I or II centers. These findings may have significant implications in the planning of trauma systems and the billing of services according to level of accreditation. PMID:16192811

Using a trauma-informed policy approach to create a resilient urban food system.

Food insecurity is associated with toxic stress and adverse long-term physical and mental health outcomes. It can be experienced chronically and also triggered or exacerbated by natural and human-made hazards that destabilize the food system. The Baltimore Food System Resilience Advisory Report was created to strengthen the resilience of the city's food system and improve short- and long-term food security. Recognizing food insecurity as a form of trauma, the report was developed using the principles of trauma-informed social policy. In the present paper, we examine how the report applied trauma-informed principles to policy development, discuss the challenges and benefits of using a trauma-informed approach, and provide recommendations for others seeking to create trauma-informed food policy. Report recommendations were developed based on: semi-structured interviews with food system stakeholders; input from community members at outreach events; a literature review; Geographic Information System mapping; and other analyses. The present paper explores findings from the stakeholder interviews. Baltimore, Maryland, USA. Baltimore food system stakeholders stratified by two informant categories: organizations focused on promoting food access (n 13) and community leaders (n 12). Stakeholder interviews informed the recommendations included in the report and supported the idea that chronic and acute food insecurity are experienced as trauma in the Baltimore community. Applying a trauma-informed approach to the development of the Baltimore Food System Resilience Advisory Report contributed to policy recommendations that were community-informed and designed to lessen the traumatic impact of food insecurity.

Trauma admissions are associated with weather and temporal factors; however, previous study results regarding these factors are contradictory. We hypothesised that weather and temporal factors have different effects on specific trauma events in an emergency medical service (EMS) system. EMS data from January 1, 2009, to December 31, 2010, were obtained from the fire department of Taipei City and associated with the local weather data. EMS trauma events were categorised into total trauma, traffic accidents (TAs), motorbike accidents (MBAs), and falls. Hourly data on trauma patients were analysed using the zero-inflated Poisson model. The hourly incidence of total trauma increased with the magnitude of precipitation (incidence rate ratio [IRR]=1.06, 1.09, and 1.11 in light, moderate, and heavy rain, respectively), and this effect was more prominent in fall patients than in patients with other injuries (IRR=1.07, 1.21, and 1.32). However, the hourly incidence of TAs and MBAs was associated only with light rain (IRR=1.11 and 1.06, respectively). An hour of sunshine exposure was associated with an increase in the hourly incidence of all groups, and higher temperatures were associated with an increased hourly incidence of total trauma, TAs, and MBAs, but not falls. The hourly incidence of falls increased only in late fall and winter. Compared with the hourly incidence between 3 am and 7 am, the hourly incidence of all groups plateaued between 7 am and 11 pm and declined from 11 pm to 3 am. During the plateau period, 2 peaks in the incidence of TAs (IRR=5.03 and 5.07, respectively) and MBAs (IRR=5.81 and 5.51, respectively) were observed during 7-11 am and 3-7 pm. The hourly incidence of total trauma, TAs, and MBAs plateaued during workdays, peaked on Fridays, declined on Saturdays, and troughed on Sundays. The incidence of falls increased only on Mondays (IRR=1.09). Weather and temporal factors had different impacts on the incidence of traffic-related accidents and falls. Therefore, EMS data may have implications in preventing injuries and planning resource use for prehospital trauma rescue. Copyright © 2015 Elsevier Ltd. All rights reserved.

Using Trauma and Injury Severity Score (TRISS)-based analysis in the development of regional risk adjustment tools to trend quality in a voluntary trauma system: the experience of the Trauma Foundation of Northeast Ohio.

Presently, no trauma system exists in Ohio. Since 1993, all hospitals in Cuyahoga County (CUY), northeast Ohio (n = 22) provide data to a trauma registry. In return, each received hospital-specific data, comparison data by trauma care level and a county-wide aggregate summary. This report describes the results of this approach in our region. All cases were entered by paper abstract or electronic download. Interrater reliability audits and z score analysis was performed by using the Major Trauma Outcome Study and the CUY 1994 baseline groups. Risk adjustment of mortality data was performed using statistical modeling and logistic regression (Trauma and Injury Severity Score, Major Trauma Outcome Study, CUY). Trauma severity measures were defined. In 1995, 3,375 patients were entered. Two hundred ninety-one died (8.6%). Severity measures differed by level of trauma care, indicating differences in case mix. Probability of survival was lowest in the Level I centers, highest in the acute care hospitals. Outcomes z scores demonstrated survival differences for all levels. In a functioning trauma system, the most severely injured patients should be cared for at the trauma centers. A low volume at acute care hospitals is desirable. By using Trauma and Injury Severity Score with community-specific constants, NE Ohio is accomplishing these goals. The Level I performance data are an interesting finding compared with the data from the Level II centers in the region

Neural Systems for Cognitive and Emotional Processing in Posttraumatic Stress Disorder

Individuals with posttraumatic stress disorder (PTSD) show altered cognition when trauma-related material is present. PTSD may lead to enhanced processing of trauma-related material, or it may cause impaired processing of trauma-unrelated information. However, other forms of emotional information may also alter cognition in PTSD. In this review, we discuss the behavioral and neural effects of emotion processing on cognition in PTSD, with a focus on neuroimaging results. We propose a model of emotion-cognition interaction based on evidence of two network models of altered brain activation in PTSD. The first is a trauma-disrupted network made up of ventrolateral PFC, dorsal anterior cingulate cortex (ACC), hippocampus, insula, and dorsomedial PFC that are differentially modulated by trauma content relative to emotional trauma-unrelated information. The trauma-disrupted network forms a subnetwork of regions within a larger, widely recognized network organized into ventral and dorsal streams for processing emotional and cognitive information that converge in the medial PFC and cingulate cortex. Models of fear learning, while not a cognitive process in the conventional sense, provide important insights into the maintenance of the core symptom clusters of PTSD such as re-experiencing and hypervigilance. Fear processing takes place within the limbic corticostriatal loop composed of threat-alerting and threat-assessing components. Understanding the disruptions in these two networks, and their effect on individuals with PTSD, will lead to an improved knowledge of the etiopathogenesis of PTSD and potential targets for both psychotherapeutic and pharmacotherapeutic interventions.

Posterior urethra primary realignment (PUPR) after complete transection may decrease the gap between the ends of the transected urethra, tamponade the retropubic bleeding, and optimize urinary drainage without the need of suprapubic catheter facilitating concurrent pelvic orthopedic and trauma procedures. Historically, the distorted anatomy after pelvic trauma has been a major surgical challenge. The purpose of the study was to assess the relationship of the severity of the pelvic fracture to the success of endoscopic and immediate PUPR following complete posterior urethral disruption using the Young-Burgess classification system. A review of our Level I trauma center database for patients diagnosed with pelvic fracture and complete posterior urethral disruption from January 2005 to April 2012 was performed. Pelvic fracture severity was categorized according to the Young-Burgees classification system. Management consisted of suprapubic catheter insertion at diagnosis followed by early urethral realignment when the patient was clinically stable. Failure of realignment was defined as inability to achieve urethral continuity with Foley catheterization. Clinical follow-up consisted of radiologic, pressure studies and cystoscopic evaluation. A total of 481 patients with pelvic trauma from our trauma registry were screened initially, and 18 (3.7%) were diagnosed with a complete posterior urethral disruption. A total of 15 primary realignments (83.3%) were performed all within 5 days of trauma. The success rate of early realignment was 100%. There was no correlation between the type of pelvic ring fracture and the success of PUPR. Postoperatively, 8 patients (53.3%) developed urethral strictures, 3 patients (20.0%) developed incontinence, and 7 patients (46.7%) reported erectile dysfunction after the trauma. The mean follow-up of these patients was 31.8 months. Endoscopic PUPR may be an effective option for the treatment of complete posterior urethral disruption and enables urinary drainage to best suit the multispecialty surgical team. The success rate of achieving primary realignment did not appear to be related to the complexity and type of pelvic ring fracture.

To establish the incidence and pattern of injuries in patients presenting to hospital with tram-related injuries. Data on tram-related injury pertaining to 2001-2008 calendar years were extracted from three datasets: the population-based Victorian State Trauma Registry for major trauma cases, the Victorian Emergency Minimum Dataset for ED presentations and the National Coroners' Information System for deaths. Incidence rates adjusted for the population of Melbourne, and trends in the incidence of tram-related ED presentations and major trauma cases, were analysed and presented as incidence rate ratios (IRR). There were 1769 patients who presented to ED after trauma related to trams in Melbourne during the study period. Of these, 107 patients had injuries classified as major trauma. There was a significant increase in the rate of ED presentations (IRR 1.03, P = 0.010) with falls (46%) the most commonly reported mechanism. Most falls occurred inside the trams. There was also a significant increase in the incidence rates of major trauma cases (IRR 1.12, P = 0.006) with pedestrians accounting for most major trauma cases. Most cases of trauma related to trams have minor injuries and are discharged following ED management. Primary prevention of falls in trams and the separation of pedestrians from trams are key areas requiring immediate improvement. In the face of increasing trauma associated with trams, continuing safety surveillance and targeted public safety messages are important to sustain trams as safe and effective mode of transport.

Trauma center performance evaluations generally include adjustment for injury severity, age, and comorbidity. However, disparities across trauma centers may be due to other differences in source populations that are not accounted for, such as socioeconomic status (SES). We aimed to evaluate whether SES influences trauma center performance evaluations in an inclusive trauma system with universal access to health care. The study was based on data collected between 1999 and 2006 in a Canadian trauma system. Patient SES was quantified using an ecologic index of social and material deprivation. Performance evaluations were based on mortality adjusted using the Trauma Risk Adjustment Model. Agreement between performance results with and without additional adjustment for SES was evaluated with correlation coefficients. The study sample comprised a total of 71,784 patients from 48 trauma centers, including 3,828 deaths within 30 days (4.5%) and 5,549 deaths within 6 months (7.7%). The proportion of patients in the highest quintile of social and material deprivation varied from 3% to 43% and from 11% to 90% across hospitals, respectively. The correlation between performance results with or without adjustment for SES was almost perfect (r = 0.997; 95% CI 0.995-0.998) and the same hospital outliers were identified. We observed an important variation in SES across trauma centers but no change in risk-adjusted mortality estimates when SES was added to adjustment models. Results suggest that after adjustment for injury severity, age, comorbidity, and transfer status, disparities in SES across trauma center source populations do not influence trauma center performance evaluations in a system offering universal health coverage.

OBJECTIVES Identify risk factors for venous thromboembolism (VTE) and develop a VTE risk assessment model for pediatric trauma patients. DESIGN, SETTING, AND PATIENTS We performed a retrospective review of patients 21 years and younger who were hospitalized following traumatic injuries at the John Hopkins level 1 adult and pediatric trauma center (1987-2011). The clinical characteristics of patients with and without VTE were compared, and multivariable logistic regression analysis was used to identify independent risk factors for VTE. Weighted risk assessment scoring systems were developed based on these and previously identified factors from patients in the National Trauma Data Bank (NTDB 2008-2010); the scoring systems were validated in this cohort from Johns Hopkins as well as a cohort of pediatric admissions from the NTDB (2011-2012). MAIN RESULTS Forty-nine of 17,366 pediatric trauma patients (0.28%) were diagnosed with VTE after admission to our trauma center. After adjusting for potential confounders, VTE was independently associated with older age, surgery, blood transfusion, higher Injury Severity Score (ISS), and lower Glasgow Coma Scale (GCS) score. These and additional factors were identified in 402,329 pediatric patients from the NTDB from 2008-2010; independent risk factors from the logistic regression analysis of this NTDB cohort were selected and incorporated into weighted risk assessment scoring systems. Two models were developed and were cross-validated in 2 separate pediatric trauma cohorts: 1) 282,535 patients in the NTDB from 2011 to 2012 2) 17,366 patients from Johns Hopkins. The receiver operator curve using these models in the validation cohorts had area under the curves that ranged 90% to 94%. CONCLUSIONS VTE is infrequent after trauma in pediatric patients. We developed weighted scoring systems to stratify pediatric trauma patients at risk for VTE. These systems may have potential to guide risk-appropriate VTE prophylaxis in children after trauma.

Traumatic injuries account for the greatest portion of global surgical burden particularly in low- and middle-income countries (LMICs). To assess effectiveness of a developing trauma system, we hypothesize that there are survival differences between direct and indirect transfer of trauma patients to a tertiary hospital in sub Saharan Africa. Retrospective analysis of 51,361 trauma patients within the Kamuzu Central Hospital (KCH) trauma registry from 2008 to 2012 was performed. Analysis of patient characteristics and logistic regression modelling for in-hospital mortality was performed. The primary study outcome is in hospital mortality in the direct and indirect transfer groups. There were 50,059 trauma patients were included in this study. 6578 patients transferred from referring facilities and 43,481 patients transported from the scene. The indirect and direct transfer cohorts were similar in age and sex. The mechanism of injury for transferred patients was 78.1% blunt, 14.5% penetrating, and 7.4% other, whereas for the scene group it was 70.7% blunt, 24.0% penetrating, and 5.2% other. Median times to presentation were 13 (4-30) and 3 (1-14)h for transferred and scene patients, respectively. Mortality rate was 4.2% and 1.6% for indirect and direct transfer cohorts, respectively. A total of 8816 patients were admitted of which 3636 and 5963 were in the transfer and scene cohort, respectively. After logistic regression analysis, the adjusted in-hospital mortality odds ratio was 2.09 (1.24-3.54); P=0.006 for indirect transfer versus direct transfer cohort, after controlling for significant covariates. Direct transfer of trauma patients from the scene to the tertiary care centre is associated with a survival benefit. Our findings suggest that trauma education and efforts directed at regionalization of trauma care, strengthening pre-hospital care and timely transfer from district hospitals could mitigate trauma-related mortality in a resource-poor setting.

Trauma-Focused CBT for Youth who Experience Ongoing Traumas

Cohen, Judith A.; Mannarino, Anthony P.; Murray, Laura A.

2011-01-01

Many youth experience ongoing trauma exposure, such as domestic or community violence. Clinicians often ask whether evidence-based treatments containing exposure components to reduce learned fear responses to historical trauma are appropriate for these youth. Essentially the question is, if youth are desensitized to their trauma experiences, will this in some way impair their responding to current or ongoing trauma? The paper addresses practical strategies for implementing one evidence-based treatment, Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) for youth with ongoing traumas. Collaboration with local therapists and families participating in TF-CBT community and international programs elucidated effective strategies for applying TF-CBT with these youth. These strategies included: 1) enhancing safety early in treatment; 2) effectively engaging parents who experience personal ongoing trauma; and 3) during the trauma narrative and processing component focusing on a) increasing parental awareness and acceptance of the extent of the youths’ ongoing trauma experiences; b) addressing youths’ maladaptive cognitions about ongoing traumas; and c) helping youth differentiate between real danger and generalized trauma reminders. Case examples illustrate how to use these strategies in diverse clinical situations. Through these strategies TF-CBT clinicians can effectively improve outcomes for youth experiencing ongoing traumas. PMID:21855140

Plasticity of serotonergic innervation of the inferior colliculus in mice following acoustic trauma

Papesh, Melissa A.; Hurley, Laura M.

2012-01-01

Acoustic trauma often results in permanent damage to the cochlea, triggering changes in processing within central auditory structures such as the inferior colliculus (IC). The serotonergic neuromodulatory system, present in the IC, is responsive to chronic changes in the activity of sensory systems. The current study investigated whether the density of serotonergic innervation in the IC is changed following acoustic trauma. The trauma stimulus consisted of an 8 kHz pure tone presented at a level of 113 dB SPL for six consecutive hours to anesthetized CBA/J mice. Following a minimum recovery period of three weeks, serotonergic fibers were visualized via histochemical techniques targeting the serotonin reuptake transporter (SERT) and quantified using stereologic probes. SERT-positive fiber densities were then compared between the traumatized and protected hemispheres of unilaterally traumatized subjects and those of controls. A significant effect of acoustic trauma was found between the hemispheres of unilaterally traumatized subjects such that the IC contralateral to the ear of exposure contained a lower density of SERT-positive fibers than the IC ipsilateral to acoustic trauma. No significant difference in density was found between the hemispheres of control subjects. Additional dimensions of variability in serotonergic fibers were seen among subdivisions of the IC and with age. The central IC had a slightly but significantly lowered density of serotonergic fibers than other subdivisions of the IC, and serotonergic fibers also declined with age. Overall, the results indicate that acoustic trauma is capable of producing modest but significant decreases in the density of serotonergic fibers innervating the IC. PMID:22101024

Firearm violence is the second leading cause of injury-related death. This study examined the use of local trauma centers as lead organizations in their communities to address firearm injury. Three trauma centers in cities with populations less than 100,000 were linked with a university-based firearm injury research center. A trauma surgeon director and coordinator partnered with communities, recruited and directed advisory boards, established a local firearm injury surveillance system, and informed communities using community-specific profiles. Primary process and outcome measures included completeness of data, development of community-specific profiles, number of data-driven consumer media pieces, number of meetings to inform policy makers, and an analysis of problems encountered. Local trauma centers in smaller communities implemented a firearm injury surveillance system, produced community-specific injury profiles, and engaged community leaders and policy makers to address firearm injury. Community-specific profiles demonstrated consistent firearm suicide rates (6.58-6.82 per 100,000) but variation in firearm homicide rates (1.08-12.5 per 100,000) across sites. There were 63 data-driven media pieces and 18 forums to inform community leaders and policy makers. Completeness of data elements ranged from 57.1% to 100%. Problems experienced were disconnected data sources, multiple data owners, potential for political fallout, limited trauma center data, skills sets of medical professionals, and sustainability. Trauma centers, when provided resources and support, with the model described, can function as lead organizations in partnering with the community to acquire and use community-specific data for local firearm injury prevention.

Trauma systems reduce mortality and improve functional outcomes from injury. Regional trauma networks have been established in several European regions to address longstanding deficiencies in trauma care. A perception of the geography and population distribution as challenging has delayed the introduction of a trauma system in Scotland. The characteristics of trauma incidents attended by the Scottish Ambulance Service were analysed, to gain a better understanding of the geospatial characteristics of trauma in Scotland. Data on trauma incidents collected by the Scottish Ambulance Service between November 2008 and October 2010 were obtained. Incident location was analysed by health board region, rurality and social deprivation. The results are presented as number of patients, average annual incidence rates and relative risks. Of the 141,668 incidents identified, 72·1 per cent occurred in urban regions. The risk of being involved in an incident was similar across the most populous regions, and decreased slightly with increasing rurality. Social deprivation was associated with greater numbers and risk. A total of 53·1 per cent of patients were taken to a large general hospital, and 38·6 per cent to a teaching hospital; the distribution was similar for the subset of incidents involving patients with physiological derangements. The majority of trauma incidents in Scotland occur in urban and deprived areas. A regionalized system of trauma care appears plausible, although the precise configuration of such a system requires further study. Copyright © 2012 British Journal of Surgery Society Ltd.

The Los Angeles County (California) Trauma Hospital System was designed to ensure that all patients requiring specialized trauma care would be transported directly to a trauma center using established trauma triage criteria. The designation and implementation of all level 1, 2, and 3 (rural) trauma centers were completed between October 1983 and July 1985. However, by February 1, 1985, one level 2 trauma center withdrew, and nine other level 2 and 3 trauma centers followed suit over the next few months and years. The reasons for closure of these 10 trauma centers were almost exclusively related to economic factors. The major impact of trauma center closure on surgical educational programs at the Drew University of Medicine and Science and the Martin Luther King, Jr/Charles R. Drew Medical Center have been additive and cumulative. The high volume of patients with trauma has been cited, sometimes correctly and sometimes incorrectly, as the primary reason for a lack of access to health care for patients without trauma. We have developed a blueprint for survival that, when fully implemented, will improve access to health care for all residents in our catchment area and optimize surgical education. While the Los Angeles County Trauma Hospital System has had many difficulties during the last 9 years, the population it serves is greater than that in 42 states in the United States. The experiences gained in Los Angeles County may be beneficial to statewide systems in the United States and in countries of comparable size.

Long term effects of childhood trauma on cortisol stress reactivity in adulthood and relationship to the occurrence of depression.

Childhood trauma may have longstanding effects on individuals' propensity to react adversely to stress, and also predisposes individuals to suffer from depression. The current study aimed to examine stress reactivity in individuals with and without a history of childhood trauma by measuring cortisol responses to the passive viewing of stressful images, specifically including images relevant to childhood trauma. In addition, participants with and without a diagnosis of current depression were studied to investigate whether cortisol stress reactivity may underlie resilience or vulnerability to depression. The study involved 17 healthy participants with and 24 without a history of childhood trauma; and 21 depressed patients with and 18 without a history of childhood trauma. Salivary cortisol was measured before, during and after participants were shown affectively laden images, including standardised scenes from the International Affective Picture System and also images suggestive of childhood abuse. Cortisol stress reactivity to the passive image viewing was compared between groups. In those who had experienced childhood trauma, cortisol stress responses were overall low and the same in those who were depressed and those who were not (mean stress reactivity variable - depressed: 0.8 nmol/l; non-depressed: 0.72 nmol/l). In contrast, cortisol stress reactivity was raised in depressed subjects relative to those who were not depressed in those without a history of childhood trauma (mean stress reactivity variable - depressed: 3.75 nmol/l; non-depressed: 0.1 nmol/l). A history of childhood trauma has longstanding effects on adulthood cortisol responses to stress, particularly in that depressed individuals with a history of childhood trauma show blunted cortisol responses. However, there were no differences between abused depressed and abused non-depressed subjects on cortisol stress responses, suggesting that such a finding does not explain subsequent susceptibility to depression. On the other hand, patients who experience depression without a history of childhood trauma show enhanced cortisol stress reactivity, which could help explain the aetiology of their depressive illnesses. Differences between the current findings and those using other pharmacological and stress challenge paradigms may relate to the type of stimuli used and to dysfunction at different levels of the hypothalamic-pituitary-adrenal (HPA) axis.

In this road map for trauma in France, we focus on the main challenges for system implementation, surgical and radiology training, and upon innovative training techniques. Regarding system organisation: procedures for triage, designation and certification of trauma centres are mandatory to implement trauma networks on a national scale. Data collection with registries must be created, with a core dataset defined and applied through all registries. Regarding surgical and radiology training, diagnostic-imaging processes should be standardised and the role of the interventional radiologist within the trauma team and the trauma network should be clearly defined. Education in surgery for trauma is crucial and recent changes in medical training in France will promote trauma surgery as a specific sub-specialty. Innovative training techniques should be implemented and be based on common objectives, scenarios and evaluation, so as to improve individual and team performances. The group formulated 14 proposals that should help to structure and improve major trauma management in France over the next 10 years.

In most low- and middle-income countries (LMICs), the resources to accurately quantify injury severity using traditional injury scoring systems are limited. Novel injury scoring systems appear to have adequate discrimination for mortality in LMIC contexts, but they have not been rigorously compared where traditional injury scores can be accurately calculated. To determine whether novel injury scoring systems perform as well as traditional ones in a HIC with complete and comprehensive data collection. Data from an American level-I trauma registry collected 2008-2013 were used to compare three traditional injury scoring systems: Injury Severity Score (ISS); Revised Trauma Score (RTS); and Trauma Injury Severity Score (TRISS); and three novel injury scoring systems: Kampala Trauma Score (KTS); Mechanism, GCS, Age and Pressure (MGAP) score; and GCS, Age and Pressure (GAP) score. Logistic regression was used to assess the association between each scoring system and mortality. Standardized regression coefficients (β 2 ), Akaike information criteria, area under the receiver operating characteristics curve, and the calibration line intercept and slope were used to evaluate the discrimination and calibration of each model. Among 18,746 patients, all six scores were associated with hospital mortality. GAP had the highest effect size, and KTS had the lowest median Akaike information criteria. Although TRISS discriminated best, the discrimination of KTS approached that of TRISS and outperformed GAP, MGAP, RTS, and ISS. MGAP was best calibrated, and KTS was better calibrated than RTS, GAP, ISS, or TRISS. The novel injury scoring systems (KTS, MGAP, and GAP), which are more feasible to calculate in low-resource settings, discriminated hospital mortality as well as traditional injury scoring systems (ISS and RTS) and approached the discrimination of a sophisticated, data-intensive injury scoring system (TRISS) in a high-resource setting. Two novel injury scoring systems (KTS and MGAP) surpassed the calibration of TRISS. These novel injury scoring systems should be considered when clinicians and researchers wish to accurately account for injury severity. Implementation of these resource-appropriate tools in LMICs can improve injury surveillance, guiding quality improvement efforts, and supporting advocacy for resource allocation commensurate with the volume and severity of trauma.

OBJECTIVE: To determine the association between measures of medical manpower available to treat trauma patients and county trauma death rates in the United States. The primary hypothesis was that greater availability of medical manpower to treat trauma injury would be associated with lower trauma death rates. SUMMARY BACKGROUND DATA: When viewed from the standpoint of the number of productive years of life lost, trauma has a greater effect on health care and lost productivity in the United States than any disease. Allocation of health care manpower to treat injuries seems logical, but studies have not been done to determine its efficacy. The effect of medical manpower and hospital resource allocation on the outcome of injury in the United States has not been fully explored or adequately evaluated. METHODS: Data on trauma deaths in the United States were obtained from the National Center for Health Statistics. Data on the number of surgeons and emergency medicine physicians were obtained from the American Hospital Association and the American Medical Association. Data on physicians who have participated in the American College of Surgeons (ACS) Advanced Trauma Life Support Course (ATLS) were obtained from the ACS. Membership information for the American Association for Surgery of Trauma (AAST) was obtained from that organization. Demographic data were obtained from the United States Census Bureau. Multivariate stepwise linear regression and cluster analysis were used to model the county trauma death rates in the United States. The Statistical Analysis System (Cary, NC) for statistical analysis was used. RESULTS: Bivariate and multivariate analyses showed that a variety of medical manpower measures and demographic factors were associated with county trauma death rates in the United States. As in other studies, measures of low population density and high levels of poverty were found to be strongly associated with increased trauma death rates. After accounting for these variables, using multivariate analysis and cluster analysis, an increase in the following medical manpower measures were associated with decreased county trauma death rates: number of board-certified general surgeons, number of board-certified emergency medicine physicians, number of AAST members, and number of ATLS-trained physicians. CONCLUSIONS: This study confirms previous work that showed a strong relation among measures of poverty, rural setting, and increased county trauma death rates. It also found that counties with more board-certified surgeons per capita and with more surgeons with an increased interest (AAST membership) or increased training (ATLS) in trauma care have lower per-capita trauma death rates.(ABSTRACT TRUNCATED AT 400 WORDS) Images Figure 1.

Severe hand traumata have a significant impact on our health system and on insurance companies, respectively. It is estimated that 33% of all occupational injuries and 9% of all invalidity pensions are due to severe hand trauma. Unfortunately, these high numbers are not only due to the severity of the trauma but to organisational deficiencies. Usually, the patient is treated at the general surgical emergency in the first place and only then forwarded to a microsurgeon. This redirection increases the time that is required for the patient to finally arrive at an expert for hand surgery. On the one hand, this problem can be explained by the population's lack of awareness for distinguished experts for hand and microsurgery, on the other hand, the emergency network, or emergency doctors in particular are not well informed about where to take a patient with a severe hand trauma - clearly a problem of communication between the hospitals and the ambulance. It is possible to tackle this problem, but put participating hand trauma centres have to work hand in hand as a network and thus exploit synergy effects. The French system "FESUM" is a good example for such a network and even comprises centres in Belgium and Switzerland. To improve the treatment of severe hand trauma, a similar alliance was initiated in Germany just recently. The pilot project "Hand Trauma Alliance" (www.handverletzung.com) was started in April 2013 and currently comprises two hospitals within the region of upper Bavaria. The network provides hand trauma replantation service on a 24/7 basis and aims at shortening the way from the accident site to the fully qualified hand surgeon, to improve the therapy of severe hand injuries and to optimise acute patient care in general. In order to further increase the alliance's impact it is intended to extend the project's scope from regional to national coverage - nevertheless, such an endeavour can only be done in collaboration with the German Society for Hand Surgery (DGH). This article comprises 2 parts. First, the state-of-the-art of acute severe hand trauma care is summarised and explained. Subsequently, the above-mentioned pilot project is described in every detail, including positive effects but also barriers that still have to be overcome. © Georg Thieme Verlag KG Stuttgart · New York.

Effective strategies that increase the extent to which child welfare professionals engage in trauma-informed case planning are needed. This study evaluated two approaches to increase trauma symptom identification and use of screening results to inform case planning. The first study evaluated the impact of training on trauma-informed screening tools for 44 child welfare professionals who screen all children upon placement into foster care. The second study evaluated a two-stage approach to training child welfare workers on case planning for children's mental health. Participants included (a) 71 newly hired child welfare professionals who received a 3-hr training and (b) 55 child welfare professionals who participated in a full-day training. Results from the first study indicate that training effectively increased knowledge and skills in administering screening tools, though there was variability in comfort with screening. In the second study, participants self-reported significant gains in their competency in identifying mental health needs (including traumatic stress) and linking children with evidence-based services. These findings provide preliminary evidence for the viability of this approach to increase the extent to which child welfare professionals are trauma informed, aware of symptoms, and able to link children and youth with effective services designed to meet their specific needs. © The Author(s) 2016.

The endocrine system may be the target of different types of trauma with varied consequences. The present article discusses trauma of the hypothalamic-pituitary axes, adrenal glands, gonads, and pancreas. In addition to changes in circulating hormone levels due to direct injury to these structures, there may be an endocrine response in the context of the stress caused by the trauma.

Rapsang, Amy Grace; Shyam, Devajit Chowlek

Trauma is a major cause of morbidity and mortality; hence severity scales are important adjuncts to trauma care in order to characterize the nature and extent of injury. Trauma scoring models can assist with triage and help in evaluation and prediction of prognosis in order to organise and improve trauma systems. Given the wide variety of scoring instruments available to assess the injured patient, it is imperative that the choice of the severity score accurately match the application. Even though trauma scores are not the key elements of trauma treatment, they are however, an essential part of improvement in triage decisions and in identifying patients with unexpected outcomes. This article provides the reader with a compendium of trauma severity scales along with their predicted death rate calculation, which can be adopted in order to improve decision making, trauma care, research and in comparative analyses in quality assessment.

A Statewide Collaboration: Ohio Level III Trauma Centers' Approach to the Development of a Benchmarking System.

PubMed

Lang, Carrie L; Simon, Diane; Kilgore, Jane

The American College of Surgeons Committee on Trauma revised the Resources for Optimal Care of the Injured Patient to include the criteria for trauma centers to participate in a risk-adjusted benchmarking system. Trauma Quality Improvement Program is currently the risk-adjusted benchmarking program sponsored by the American College of Surgeons, which will be required of all trauma centers to participate in early 2017. Prior to this, there were no risk-adjusted programs for Level III verified trauma centers. The Ohio Society of Trauma Nurse Leaders is a collaborative group made up of trauma program managers, coordinators, and other trauma leaders who meet 6 times a year. Within this group, a Level III Subcommittee was formed initially to provide a place for the Level III centers to discuss issues specific to the Level III centers. When the new requirement regarding risk-adjustment became official, the subcommittee agreed to begin reporting simple data points with the idea to risk adjust in the future.

Changes in urine composition after trauma facilitate bacterial growth

PubMed Central

2012-01-01

Background Critically ill patients including trauma patients are at high risk of urinary tract infection (UTI). The composition of urine in trauma patients may be modified due to inflammation, systemic stress, rhabdomyolysis, life support treatment and/or urinary catheter insertion. Methods Prospective, single-centre, observational study conducted in patients with severe trauma and without a history of UTIs or recent antibiotic treatment. The 24-hour urine samples were collected on the first and the fifth days and the growth of Escherichia coli in urine from patients and healthy volunteers was compared. Biochemical and hormonal modifications in urine that could potentially influence bacterial growth were explored. Results Growth of E. coli in urine from trauma patients was significantly higher on days 1 and 5 than in urine of healthy volunteers. Several significant modifications of urine composition could explain these findings. On days 1 and 5, trauma patients had an increase in glycosuria, in urine iron concentration, and in the concentrations of several amino acids compared to healthy volunteers. On day 1, the urinary osmotic pressure was significantly lower than for healthy volunteers. Conclusion We showed that urine of trauma patients facilitated growth of E. coli when compared to urine from healthy volunteers. This effect was present in the first 24 hours and until at least the fifth day after trauma. This phenomenon may be involved in the pathophysiology of UTIs in trauma patients. Further studies are required to define the exact causes of such modifications. PMID:23194649

Trauma remains the primary cause of death in individuals under 40 years of age in Canada. In Quebec, the Trauma Care Continuum (TCC) has been demonstrated to be effective in decreasing the mortality rate among trauma victims. Although rural citizens are at greater risk for trauma and trauma death, no empirical data concerning the effectiveness of the TCC for the rural population in Quebec are available. The emergency departments (EDs) are important safety nets for rural citizens. However, our data indicate that access to diagnostic support services, such as intensive care units and CT is limited in rural areas. The objectives are to (1) draw a portrait of trauma services in rural EDs; (2) explore geographical variations in trauma care in Quebec; (3) identify adaptable factors that could reduce variation; and (4) establish consensus solutions for improving the quality of care. The study will take place from November 2015 to November 2018. A mixed methodology (qualitative and quantitative) will be used. We will include data (2009-2013) from all trauma victims treated in the 26 rural EDs and tertiary/secondary care centres in Quebec. To meet objectives 1 and 2, data will be gathered from the Ministry's Database of the Quebec Trauma Registry Information System. For objectives 3 and 4, the project will use the Delphi method to develop consensus solutions for improving the quality of trauma care in rural areas. Data will be analysed using a Poisson regression to compare mortality rate during hospital stay or death on ED arrival (objectives 1 and 2). Average scores and 95% CI will be calculated for the Delphi questionnaire (objectives 3 and 4). This protocol has been approved by CSSS Alphonse-Desjardins research ethics committee (Project MP-HDL-2016-003). The results will be published in peer-reviewed journals.

The South Korean government recently developed a master plan for establishing a national trauma system based on the implementation of regional trauma centers. We aimed to compare outcomes between severely injured patients treated at a recently established South Korean trauma center and matched patients treated in American level-1 trauma centers. Two cohorts were selected from an institutional trauma database at Ajou University Medical Center (AUMC) and the American National Trauma Data Bank. Adult patients with an Injury Severity Score of ≥9 were included. Patients were matched based on covariates that affect mortality, using 1:1 propensity score matching. We compared outcomes between the two datasets and performed survival analyses. We created 1,451 and 2,103 matched pairs for the pre-trauma center and post-trauma center periods, respectively. The in-hospital mortality rate was higher in the institutional trauma database pre-trauma center period compared with the American National Trauma Data Bank (11.6% versus 8.1%, P<.001). However, the mortality rate decreased in the institutional trauma database post-trauma center period and was similar to that in the American National Trauma Data Bank (6.9% versus 6.8%, P=.903). Being treated at Ajou University Medical Center Trauma Center was significantly associated with higher mortality during the pre-trauma center period (OR: 1.842, 95% CI: 1.336-2.540; P<.001), although no significant association was observed during the post-trauma center period (OR: 1.102, 95% CI: 0.827-1.468; P=.509). The mortality rate improved after a trauma center was established in a South Korean hospital and is similar to that from matched cases treated at American level-1 trauma centers. Thus, creating trauma centers and a regional trauma system may improve outcomes in major trauma cases. Copyright © 2018 Elsevier Inc. All rights reserved.

A Sphingosine-1 Phosphate agonist (FTY720) limits trauma/hemorrhagic shock induced multiple organ dysfunction syndrome

BACKGROUND Trauma/hemorrhagic shock is one of the major consequences of battlefield injury as well as civilian trauma. FTY720 (sphingosine-1 phosphate agonist) has the capability to decrease the activity of the innate and adaptive immune systems and, at the same time, maintain endothelial cell barrier function and vascular homeostasis during stress. For this reason, we hypothesize that FTY720, as part of resuscitation therapy, would limit T/HS induced multiple organ dysfunction syndrome (MODS) in a rodent trauma-hemorrhagic shock (T/HS) model. METHODS Rats subjected to trauma/sham-shock (T/SS) or T/HS (30 mm Hg × 90 min), were administered FTY720 (1 mg/kg) post-T/HS during volume resuscitation. Lung injury (permeability to Evans Blue dye), PMN priming (respiratory burst activity), and RBC rigidity were measured. In addition, lymph duct cannulated rats were used to quantify the effect of FTY720 on gut injury (permeability and morphology) and the biologic activity of T/HS vs. T/SS lymph on PMN-RB and RBC deformability. RESULTS T/HS-induced increased lung permeability, PMN priming and RBC rigidity were all abrogated by FTY720. The systemic protective effect of FTY720 was only partially at the gut level, since FTY720 did not prevent T/HS-induced gut injury (morphology or permeability,) however, it did abrogate T/HS lymph-induced increased respiratory burst and RBC rigidity. CONCLUSION FTY720 limited T/HS-induced MODS (lung injury, red cell injury, and neutrophil priming) as well as T/HS lymph bioactivity, although it did not limit gut injury. PMID:25004059

Overall mortality ascribable to multiple traumas, that in Italy is responsible for about 8,000 death/year, is strictly dependent on the function of the so called Trauma Care System. This study reports on an epidemiological survey conducted in the urban area of Florence along a 23-month period (from Jan 97 to Nov 99), with the aim to identify the typology of traumas and the first aid care delivered to the person until hospital admission. These data were compared to those collected in the urban area of Bologna because the composition of the first-aid team is different, being nurses, in Bologna, an integral component of the first aid system. On a total of 118 multiple traumas, 17% was represented by isolated head trauma, while in 72% involvement of other organs was present in addition to the head; 11% of cases were abdominal or thoracic traumas, 1% of lower extremities. In 46% the cause of trauma was a car accident. The complexity of care delivered to the person with trauma was less in the Florence survey, as indicated by the immobilization of patients, performed in only 11% of cases as compared to 47% in Bologna, by the application of the cervical collar, applied in 12% versus 62% of traumas. Although the two samples are not strictly comparable, these data suggest that the presence of nurses in the Trauma Care System can be one of the elements of improvement of the quality of delivered care.

Poor psychological outcomes are common among trauma survivors, yet not all survivors experience adverse sequelae. The current study examined links between cumulative trauma exposure as a function of the level of betrayal (measured by the relational closeness of the survivor and the perpetrator), trauma appraisals, gender, and trauma symptoms. Participants were 273 college students who reported experiencing at least one traumatic event on a trauma checklist. Three cumulative indices were constructed to assess the number of different types of traumas experienced that were low (LBTs), moderate (MBTs), or high in betrayal (HBTs). Greater trauma exposure was related to more symptoms of depression, dissociation, and PTSD, with exposure to HBTs contributing the most. Women were more likely to experience HBTs than men, but there were no gender differences in trauma-related symptoms. Appraisals of trauma were predictive of trauma-related symptoms over and above the effects explained by cumulative trauma at each level of betrayal. The survivor's relationship with the perpetrator, the effect of cumulative trauma, and their combined impact on trauma symptomatology are discussed.

Pain and trauma in negative pressure wound therapy: a review.

Upton, Dominic; Andrews, Abbye

2015-02-01

Negative pressure wound therapy (NPWT) is considered an effective wound treatment, but there are a number of issues that need to be addressed for improvements to be made. This review aimed to explore the literature relating to the pain and skin trauma that may be experienced during NPWT. A literature search was carried out using the following databases: Academic Search Complete, CINAHL, PsychINFO, MEDLINE and PsyARTICLES. A total of 30 articles were reviewed. Studies reported varying levels of pain in patients undergoing NPWT, with certain treatment factors affecting the level of pain, such as the NPWT system and the dressing/filler used. Similarly, although there is much less research exploring NPWT-related trauma, findings suggest that dressing and filler type may impact on whether trauma occurs. However, further research needs to consider the different stages of NPWT and how pain and trauma can be minimised during the whole procedure. As both pain and skin trauma impact on the patient's well-being and on wound healing, it is essential that research further explores the factors that may affect the experience of pain and trauma, so as to inform developments in wound care. © 2013 The Authors.

Trauma is one of the leading causes of death in Taiwan, and its medical expenditure escalated drastically. This study aimed to explore the effectiveness of trauma team, which was established in September 2010, on medical resource utilization and quality of care among major trauma patients. This was a retrospective study, using trauma registry data bank and inpatient medical service charge databases. Study subjects were major trauma patients admitted to a medical center in Tainan during 2009 and 2013, and was divided into case group (from January, 2011 to August, 2013) and comparison group (from January, 2009 to August, 2010). Significant reductions in several items of medical resource utilization were identified after the establishment of trauma team. In the sub-group of patients who survived to discharge, examination, radiology and operation charges declined significantly. The radiation and examination charges reduced significantly in the subcategories of ISS = 16 ~ 24 and ISS > 24 respectively. However, no significant effectiveness on quality of care was identified. The establishment of trauma team is effective in containing medical resource utilization. In order to verify the effectiveness on quality of care, extended time frame and extra study subjects are needed.

The practice of repeating computed tomography (re-CT) is common among trauma patients transferred between hospitals incurring additional cost and radiation exposure. This study sought to evaluate the effectiveness of implementing modern cloud-based technology (lifeIMAGE) across a regional trauma system to reduce the incidence of re-CT imaging. This is a prospective interventional study to evaluate outcomes after implementation of lifeIMAGE in January 2012. Key outcomes were rates of CT imaging, including the rates and costs of re-CT from January 2009 through December 2012. There were 1,081 trauma patients transferred from participating hospitals during the study period (657 patients before and 425 patients after implementation), with the overall re-CT rate of 20.5%. Rates of any CT imaging at referring hospitals decreased (62% vs. 55%, p < 0.05) and also decreased at the accepting regional Level I center (58% vs. 52%, p < 0.05) following system implementation. There were 639 patients (59%) who had CT imaging performed before transfer (404 patients before and 235 patients after implementation). Of these patients, the overall re-CT rate decreased from 38.4% to 28.1% (p = 0.01). Rates of re-CT of the head (21% vs. 11%, p = 0.002), chest (7% vs. 3%, p = 0.05), as well as abdomen and pelvis (12% vs. 5%, p = 0.007) were significantly reduced following system implementation. The cost of repeat imaging per patient was significantly lower following system implementation (mean charges, $1,046 vs. $589; p < 0.001). These results were more pronounced in a subgroup of patients with an Injury Severity Score (ISS) of greater than 14, with a reduction in overall re-CT rate from 51% to 30% (p = 0.03). The implementation of modern cloud-based technology across the regional trauma system resulted in significant reductions in re-CT imaging and cost.

The goal of this work was to examine associations among childhood trauma, combat trauma, and substance use (alcohol problems, frequent heavy drinking [FHD], current cigarette smoking, and current/lifetime drug use) and the interaction effects of childhood trauma and combat exposure on those associations among National Guard/reserve soldiers. Participants (N = 248) completed an electronic survey asking questions about their military experiences, physical and mental health, and substance use. Childhood trauma and combat exposure were examined jointly in regression models, controlling for age, marital satisfaction, and number of deployments. Childhood trauma was associated with current drug use (trend level, odds ratio [OR] = 1.44, 95% confidence interval [CI]: 0.97, 2.14; P = .072) in the main effect model; however, there was not a significant interaction with combat. Combat exposure had a significant interaction with childhood trauma on alcohol problems (b = -0.56, 95% CI: -1.12, -0.01; P = .048), FHD (b = -0.27, 95% CI: -0.47, -0.08; P = .007), and lifetime drug use (OR = 1.78, 95% CI: 1.04, 3.04; P = .035). There were no associations with either of the trauma measures and current cigarette smoking. These results demonstrate that childhood and combat trauma have differential effects on alcohol use, such that combat trauma may not add to the effect on alcohol use in those with greater child maltreatment but may contribute to greater alcohol use among those with low child maltreatment. As expected, childhood and combat trauma had synergistic effects on lifetime drug use. Screening for multiple types of trauma prior to enlistment and/or deployment may help to identify at-risk individuals and allow time for early intervention to prevent future adverse outcomes.

Cumulative Trauma and Adjustment in Women Exposed to a Campus Shooting: Examining the Role of Appraisals and Social Support.

2017-05-01

Experiencing repeated trauma can have increasingly detrimental effects on psychosocial functioning after subsequent stressors. These effects may be intensified for victims of interpersonal traumas given that these events are often associated with heightened risk for adverse outcomes. To better understand this relationship, the present study prospectively examined the effect of pre-shooting trauma exposure (i.e., interpersonal vs. non-interpersonal trauma) on psychological functioning (i.e., posttraumatic stress symptoms, depression) following a mass campus shooting. Based on previous research, it was expected that negative appraisals and social support would mediate this relationship. A sample of 515 college women reporting prior trauma exposure was assessed at four time points following the shooting (i.e., pre-shooting, 1-month, 6-months, and 12-months post-shooting). Bootstrap analyses with bias-corrected confidence intervals were conducted. Contrary to expectation, pre-shooting trauma exposure was unrelated to 12-month post-shooting outcomes and neither negative appraisals nor social support at 6-months post-shooting emerged as mediators. Interestingly, a history of non-interpersonal trauma was associated with greater post-shooting family and friend support than a history of interpersonal trauma. Ad hoc analyses showed that pre-shooting symptom severity and level of exposure to the shooting had indirect effects on post-shooting outcomes via post-shooting negative appraisals. These findings support that cumulative trauma, regardless of type, may not have an additive effect unless individuals develop clinically significant symptoms following previous trauma. Trauma severity also appears to play a meaningful role.

Trauma system in Greece: Quo Vadis?

Anagnostou, Evangelos; Larentzakis, Andreas; Vassiliu, Pantelis

2018-05-23

Implementation of trauma systems has markedly assisted in improving outcomes of the injured patient. However, differences exist internationally as diverse social factors, economic conditions and national particularities are placing obstacles. The purpose of this paper is to critically evaluate the current Greek trauma system, provide a comprehensive review and suggest key actions. An exhaustive search of the - scarce on this subject - English and Greek literature was carried out to analyze all the main components of the Greek trauma system, according to American College of Surgeons' criteria, as well as the WHO Trauma Systems Maturity Index. Regarding prevention, efforts are in the right direction lowering the road traffic incidents-related death rate, however rural and insular regions remain behind. Hellenic Emergency Medical Service (EKAB) has well-defined communications and emergency phone line but faces problems with educating people on how to use it properly. In addition, equal and systematic training of ambulance personnel is a challenge, with the lack of pre-hospital registry and EMS quality assessment posing a question on where the related services are currently standing. Redistribution of facilities' roles with the establishment of the first formal trauma centre in the existing infrastructure would facilitate the development of a national registry and introduction of the trauma surgeon subspecialty with proper training potential. Definite rehabilitation institutional protocols that include both inpatient and outpatient care are needed. Disaster preparedness entails an extensive national plan and regular drills, mainly at the pre-hospital level. The lack, however, of any accompanying quality assurance programs hampers the effort to yield the desirable results. Despite recent economic crisis in Greece, actions solving logistics and organising issues may offer a well-defined, integrated trauma system without uncontrollably raising the costs. Political will is needed for reforms that use pre-existing infrastructure and working power in a more efficient way, with a first line priority being the establishment of the first major trauma centre that could function as the cornerstone for the building of the Greek trauma system.

Homeless youth are at increased risk for involvement in the criminal justice system. This study investigated childhood trauma as a risk factor for arrest or jail among a sample of youth seeking services at drop in, shelter, and transitional housing settings, while controlling for more established risk factors including: substance use, peer deviance, and engagement in survival behaviors. Standardized and researcher developed measures collected quantitative data through face-to-face interviews with youth (N = 202). Two sequential logic regression models identified significant predictors of arrest and jail, with a particular interest in the effects of childhood maltreatment. Youth with a history of physical abuse were nearly twice as likely to be arrested and to be jailed compared to non-abused youth, controlling for the significant influence of drug use and survival behaviors. These findings suggest the need for trauma screening and trauma-informed services for homeless youth at risk of illegal behavior.

Law enforcement-applied tourniquets: a case series of life-saving interventions.

PubMed

Callaway, David W; Robertson, Joshua; Sztajnkrycer, Matthew D

2015-01-01

Although the epidemiology of civilian trauma is distinct from that encountered in combat, in both settings, extremity hemorrhage remains a major preventable cause of potential mortality. The current paper describes the largest case series in the literature in which police officers arriving prior to emergency medical services applied commercially available field tourniquets to civilian victims of violent trauma. Although all 3 patients with vascular injury arrived at the receiving emergency department in extremis, they were successfully resuscitated and survived to discharge without major morbidity. While this outcome is likely multifactorial and highlights the exceptional care delivered by the modern trauma system, tourniquet application appears to have kept critically injured patients alive long enough to reach definitive trauma care. No patient had a tourniquet-related complication. This case series suggests that law enforcement officers can effectively identify indications for tourniquets and rapidly apply such life-saving interventions.

In 1994, the Hong Kong Special Administrative Region (HKSAR) introduced plans to implement a trauma system based on the recommendations outlined by Professor Donald Trunkey in his report to the local Hospital Authority. Five government-subsidized public hospitals were subsequently designated as trauma centers in 2003. This article reviews the initial experience in these five centers. Prospective trauma registries from January 2004 to December 2008 were reviewed. Primary clinical outcome measures were hospital mortality. The Trauma and Injury Severity Score methodology was used for benchmarking with the Major Trauma Outcome Study (MTOS) database. The majority (83.3%) of the 10,462 patients suffered from blunt trauma. Severe injury, defined as Injury Severity Score>15, occurred in 29.7% of patients. The leading causes of trauma were motor vehicle collisions and falls, with crude hospital mortality rates of 6.9% and 10.7%, respectively. The M-statistic was 0.95, indicating comparable case-mix with the MTOS. The worst outcome occurred in the first year. Significant improvement was seen in patients with penetrating injuries. By 2008, these patients had significantly higher survival rates than expected (Z-statistic=0.85). Although the overall mortality rates for blunt trauma were higher than expected, the difference was no longer statistically significant from the second year onward. The case-mix of trauma patients in the HKSAR is comparable with that of the MTOS. A young trauma system relatively unburdened by dissimilar reimbursement and patient access issues may achieve significant improvement and satisfactory patient outcomes. Our findings may serve as a useful benchmark for HK and other Southeast Asian cities and trauma systems to establish local coefficients for future evaluations.

Trauma developmental theory identifies gender discrimination (GD) as a type of persistent, ongoing trauma that has the potential for serious, negative effects on mental health. This study was conducted to examine the potential role of GD in the development of cumulative trauma disorders (CTD) and symptoms of posttraumatic stress disorder (PTSD) as well as the role of GD in mediating the effects of other traumas on these disorders. The sample included 160 female torture survivors from more than 30 countries. Measures of PTSD, CTD, and types of trauma exposure were acquired as part of a larger study on refugee torture survivors. Structural equation modeling was used to test several plausible models for the direct and indirect effects of GD on PTSD and CTD, within the context of other trauma exposure. Results suggest that GD mediates the effects of identity traumas on CTD and PTSD. GD also had direct effects on CTD, including relationships with dissociation, suicidality, and deficits in executive function. GD did not appear to directly influence the development of PTSD. The implications of these results for assessment and treatment of women's trauma-related disorders as well as strategies for their prevention are discussed.

The effectiveness of emergency medical interventions can be best evaluated using time-to-event statistical methods with time-varying covariates (TVC), but this approach is complicated by uncertainty about the actual times of death. We therefore sought to evaluate the effect of hospital intervention on mortality after penetrating trauma using a method that allowed for interval censoring of the precise times of death. Data on persons with penetrating trauma due to interpersonal assault were combined from the 2008 to 2010 National Trauma Data Bank (NTDB) and the 2004 to 2010 National Violent Death Reporting System (NVDRS). Cox and Weibull proportional hazards models for survival time (t SURV ) were estimated, with TVC assumed to have constant effects for specified time intervals following hospital arrival. The Weibull model was repeated with t SURV interval-censored to reflect uncertainty about the precise times of death, using an imputation method to accommodate interval censoring along with TVC. All models showed that mortality was increased by older age, female sex, firearm mechanism, and injuries involving the head/neck or trunk. Uncensored models showed a paradoxical increase in mortality associated with the first hour in a hospital. The interval-censored model showed that mortality was markedly reduced after admission to a hospital, with a hazard ratio (HR) of 0.68 (95% CI 0.63, 0.73) during the first 30 min declining to a HR of 0.01 after 120 min. Admission to a verified level I trauma center (compared to other hospitals in the NTDB) was associated with a further reduction in mortality, with a HR of 0.93 (95% CI 0.82, 0.97). Time-to-event models with TVC and interval censoring can be used to estimate the effect of hospital care on early mortality after penetrating trauma or other acute medical conditions and could potentially be used for interhospital comparisons.

Trauma care capacity assessments in developing countries have generated evidence to support advocacy, detailed baseline capabilities, and informed targeted interventions. However, serial assessments to determine the effect of capacity improvements or changes over time have rarely been performed. To compare the availability of trauma care resources in Ghana between 2004 and 2014 to assess the effects of a decade of change in the trauma care landscape and derive recommendations for improvements. Capacity assessments were performed using direct inspection and structured interviews derived from the World Health Organization's Guidelines for Essential Trauma Care. In Ghana, 10 hospitals in 2004 and 32 hospitals in 2014 were purposively sampled to represent those most likely to care for injuries. Clinical staff, administrators, logistic/procurement officers, and technicians/biomedical engineers who interacted, directly or indirectly, with trauma care resources were interviewed at each hospital. Availability of items for trauma care was rated from 0 (complete absence) to 3 (fully available). Factors contributing to deficiency in 2014 were determined for items rated lower than 3. Each item rated lower than 3 at a specific hospital was defined as a hospital-item deficiency. Scores for total number of hospital-item deficiencies were derived for each contributing factor. There were significant improvements in mean ratings for trauma care resources: district-level (smaller) hospitals had a mean rating of 0.8 for all items in 2004 vs 1.3 in 2014 (P = .002); regional (larger) hospitals had a mean rating of 1.1 in 2004 vs 1.4 in 2014 (P = .01). However, a number of critical deficiencies remain (eg, chest tubes, diagnostics, and orthopedic and neurosurgical care; mean ratings ≤ 2). Leading contributing factors were item absence (503 hospital-item deficiencies), lack of training (335 hospital-item deficiencies), and stockout of consumables (137 hospital-item deficiencies). There has been significant improvement in trauma care capacity during the past decade in Ghana; however, critical deficiencies remain and require urgent redress to avert preventable death and disability. Serial capacity assessment is a valuable tool for monitoring efforts to strengthen trauma care systems, identifying what has been successful, and highlighting needs.

Psychological Trauma in the Context of Familial Relationships: A Concept Analysis.

Isobel, Sophie; Goodyear, Melinda; Foster, Kim

2017-01-01

Many forms of psychological trauma are known to develop interpersonally within important relationships, particularly familial. Within the varying theoretical constructs of psychological traumas, and distinct from the processes of diagnosis, there is a need to refine the scope and definitions of psychological traumas that occur within important familial relationships to ensure a cohesive evidence base and fidelity of the concept in application to practice. This review used a philosophical inquiry methodology of concept analysis to identify the definitions, antecedents, characteristics, and consequences of the varying conceptualizations of psychological trauma occurring within important relationships. Interactions between concepts of interpersonal trauma, relational trauma, betrayal trauma, attachment trauma, developmental trauma, complex trauma, cumulative trauma, and intergenerational trauma are presented. Understanding of the discrete forms and pathways of transmission of psychological trauma between individuals, including transgenerationally within families, creates opportunities for prevention and early intervention within trauma-focused practice. This review found that concepts of psychological trauma occurring within familial relationships are not exclusive of each other but overlap in their encompassment of events and circumstances as well as the effect on individuals of events in the short term and long term. These traumas develop and are transmitted in the space between people, both purposefully and incidentally, and have particularly profound effects when they involve a dependent infant or child. Linguistic and conceptual clarity is paramount for trauma research and practice.

2012-02-01

A registry-based analysis revealed imprecise informal one-tiered trauma team activation (TTA) in a primary trauma centre. A two-tiered TTA protocol was introduced and analysed to examine its impact on triage precision and resource utilization. Interhospital transfers and patients admitted by non-healthcare personnel were excluded. Undertriage was defined as the fraction of major trauma victims (New Injury Severity Score over 15) admitted without TTA. Overtriage was the fraction of TTA without major trauma. Of 1812 patients, 768 had major trauma. Overall undertriage was reduced from 28·4 to 19·1 per cent (P < 0·001) after system revision. Overall overtriage increased from 61·5 to 71·6 per cent, whereas the mean number of skilled hours spent per overtriaged patient was reduced from 6·5 to 3·5 (P < 0·001) and the number of skilled hours spent per major trauma victim was reduced from 7·4 to 7·1 (P < 0·001). Increasing age increased risk for undertriage and decreased risk for overtriage. Falls increased risk for undertriage and decreased risk for overtriage, whereas motor vehicle-related accidents showed the opposite effects. Patients triaged to a prehospital response involving an anaesthetist had less chance of both undertriage and overtriage. A two-tiered TTA protocol was associated with reduced undertriage and increased overtriage, while trauma team resource consumption was reduced. NCT00876564 (http://www.clinicaltrials.gov).

2008-07-13

We analysed the trauma triage system at a specific level I trauma centre to assess rates of over- and undertriage and to support recommendations for system improvements. The triage process is designed to estimate the severity of patient injury and allocate resources accordingly, with potential errors of overestimation (overtriage) consuming excess resources and underestimation (undertriage) potentially leading to medical errors.We first modelled the overall trauma system using risk analysis methods to understand interdependencies among the actions of the participants. We interviewed six experienced trauma surgeons to obtain their expert opinion of the over- and undertriage rates occurring in the trauma centre. We then assessed actual over- and undertriage rates in a random sample of 86 trauma cases collected over a six-week period at the same centre. We employed Bayesian analysis to quantitatively combine the data with the prior probabilities derived from expert opinion in order to obtain posterior distributions. The results were estimates of overtriage and undertriage in 16.1 and 4.9% of patients, respectively. This Bayesian approach, which provides a quantitative assessment of the error rates using both case data and expert opinion, provides a rational means of obtaining a best estimate of the system's performance. The overall approach that we describe in this paper can be employed more widely to analyse complex health care delivery systems, with the objective of reduced errors, patient risk and excess costs.

To explore injured patients' experiences of trauma care to identify areas for improvement in service delivery. Qualitative study using in-depth, semi-structured interviews, conducted from 1 April 2011 to 31 January 2012, with 120 trauma patients registered by the Victorian State Trauma Registry and the Victorian Orthopaedic Trauma Outcomes Registry and managed at the major adult trauma services (MTS) in Victoria. Emergent themes from patients' experiences of acute, rehabilitation and post-discharge care in the Victorian State Trauma System (VSTS). Patients perceived their acute hospital care as high quality, although 3s with communication and surgical management delays were common. Discharge from hospital was perceived as stressful, and many felt ill prepared for discharge. A consistent emerging theme was the sense of a lack of coordination of post-discharge care, and the absence of a consistent point of contact for ongoing management. Most patients' primary point of contact after discharge was outpatient clinics at the MTS, which were widely criticised because of substantial delays in receiving an appointment, prolonged waiting times, limited time with clinicians, lack of continuity of care and inability to see senior clinicians. This study highlights perceived 3s in the patient care pathway in the VSTS, especially those relating to communication, information provision and post-discharge care. Trauma patients perceived the need for a single point of contact for coordination of post-discharge care.

Chest trauma has a significant relevance on outcome after severe trauma. Clinically, impaired lung function typically occurs within 72 hours after trauma. However, the underlying pathophysiological mechanisms are still not fully elucidated. Therefore, we aimed to establish an experimental long-term model to investigate physiological, morphologic and inflammatory changes, after severe trauma. Male pigs (sus scrofa) sustained severe trauma (including unilateral chest trauma, femur fracture, liver laceration and hemorrhagic shock). Additionally, non-injured animals served as sham controls. Chest trauma resulted in severe lung damage on both CT and histological analyses. Furthermore, severe inflammation with a systemic increase of IL-6 (p = 0.0305) and a local increase of IL-8 in BAL (p = 0.0009) was observed. The pO2/FiO2 ratio in trauma animals decreased over the observation period (p < 0.0001) but not in the sham group (p = 0.2967). Electrical Impedance Tomography (EIT) revealed differences between the traumatized and healthy lung (p < 0.0001). In conclusion, a clinically relevant, long-term model of blunt chest trauma with concomitant injuries has been developed. This reproducible model allows to examine local and systemic consequences of trauma and is valid for investigation of potential diagnostic or therapeutic options. In this context, EIT might represent a radiation-free method for bedside diagnostics. PMID:28000769

Exposure to chronic and traumatic stress has been associated with the dysregulation of crucial stress response systems. Acculturation has been associated with unique forms of chronic psychosocial stress. The purpose of this study was to examine the effects of exposure to early traumatic stress and acculturation on dysregulation of the cortisol awakening response (CAR) in Mexican-American adults. Salivary cortisol samples were collected at awakening and 30, 45, and 60 min thereafter, on two consecutive weekdays from 59 healthy Mexican-American adult males (26) and females (33), ages 18-38 years. Participants were assessed for level of acculturation and exposure to early trauma. Data were analyzed using a mixed effects regression model with repeated measures at four time points. Mixed effects regression results indicated a significant Early Trauma x Time interaction (p=.0029) and a significant Acculturation x Time interaction (p=.0015), after controlling for age and sex. Subsequent analyses of the interaction of Trauma x Acculturation x Time showed that more than minimal exposure to either risk factor was associated with attenuation of the awakening cortisol response (p=.0002). Higher levels of acculturation with greater Anglo-orientation were associated with attenuation of the CAR in Mexican-American adults. Both moderate and higher levels of exposure to early trauma were associated with an attenuated CAR. However, greater exposure to both risk factors was only incrementally worse than exposure to either one. Copyright (c) 2010 Elsevier Inc. All rights reserved.

This study aimed to investigate whether attachment insecurity mediates the relationship between childhood trauma and adult dissociation, specifically with regard to individual forms of childhood maltreatment. Psychiatric outpatients who visited a specialized trauma clinic (n = 115) participated in the study. Data were collected via the Childhood Trauma Questionnaire, Revised Adult Attachment Scale, and Dissociative Experience Scale. Structural equation modeling and path analysis were performed to analyze the mediating effects of attachment insecurity on the relationship between childhood trauma and adult dissociation. Greater childhood trauma was associated with higher dissociation, and the relationship between them was fully mediated by attachment anxiety. In path analysis of trauma subtypes, the effects of emotional abuse, physical abuse, and physical neglect as a child on adult dissociation were found to be fully mediated by attachment anxiety. The effect of sexual abuse on dissociation was mediated by a synergistic effect from both attachment anxiety and attachment avoidance. Regarding emotional neglect, a countervailing interaction was discovered between the direct and indirect effects thereof on dissociation; the indirect effect of emotional neglect on dissociation was partially mediated by attachment insecurity. Specific aspects of attachment insecurity may help explain the relationships between individual forms of childhood trauma and adult dissociative symptoms. Tailored treatments based on affected areas of attachment insecurity may improve outcomes among patients with dissociative symptoms and a history of childhood trauma.

To examine the effect of sleep deprivation compared to sleep, immediately after experimental trauma stimuli on the development of intrusive memories to that trauma stimuli. Participants were exposed to a film with traumatic content (trauma film). The immediate response to the trauma film was assessed, followed by either total sleep deprivation (sleep deprived group, N = 20) or sleep as usual (sleep group, N = 22). Twelve hours after the film viewing the initial psychological effect of the trauma film was measured and for the subsequent 6 days intrusive emotional memories related to the trauma film were recorded in daily life. Academic sleep laboratory and participants' home environment. Healthy paid volunteers. On the first day after the trauma film, the psychological effect as assessed by the Impact of Event Scale - Revised was lower in the sleep deprived group compared to the sleep group. In addition, the sleep deprived group reported fewer intrusive emotional memories (mean 2.28, standard deviation [SD] 2.91) compared to the sleep group (mean 3.76, SD 3.35). Because habitual sleep/circadian patterns, psychological health, and immediate effect of the trauma film were similar at baseline for participants of both groups, the results cannot be accounted for by pre-existing inequalities between groups. Our findings suggest that sleep deprivation on one night, rather than sleeping, reduces emotional effect and intrusive memories following exposure to experimental trauma. © 2015 Associated Professional Sleep Societies, LLC.

Beyond individual war trauma: domestic violence against children in Afghanistan and Sri Lanka.

To date, research on the psychosocial consequences of mass trauma resulting from war and organized violence on children has primarily focused on the individual as the unit of treatment and analysis with particular focus on mental disorders caused by traumatic stress. This body of research has stimulated the development of promising individual-level treatment approaches for addressing psychological trauma. In contrast, there is virtually no literature addressing the effects of mass trauma on the family and community systems. Research conducted in Sri Lanka and Afghanistan, two long-standing war-torn societies, found that in addition to multiple exposure to war or disaster-related traumatic events children also indicated high levels of exposure to family violence. These findings point to the need for conjoint family- and community-based programs of prevention and intervention that are specifically tailored for the context of the affected society. In particular, programs should take issues such as poverty, child labor, and parental alcohol use into account in assessing and treating children in the aftermath of mass trauma.

Exposure to traumatic experiences among youth is a serious public health concern. A trauma-informed public behavioral health system that emphasizes core principles such as understanding trauma, promoting safety, supporting consumer autonomy, sharing power, and ensuring cultural competence, is needed to support traumatized youth and the providers who work with them. This article describes a case study of the creation and evaluation of a trauma-informed publicly funded behavioral health system for children and adolescents in the City of Philadelphia (the Philadelphia Alliance for Child Trauma Services; PACTS) using the Exploration, Preparation, Implementation, and Sustainment (EPIS) as a guiding framework. We describe our evaluation of this effort with an emphasis on implementation determinants and outcomes. Implementation determinants include inner context factors, specifically therapist knowledge and attitudes (N = 114) towards evidence-based practices. Implementation outcomes include information on rate of PTSD diagnoses in agencies over time, number of youth receiving TF-CBT over time, and penetration (i.e., number of youth receiving TF-CBT divided by the number of youth screening positive on trauma screening). We describe lessons learned from our experiences building a trauma-informed public behavioral health system in the hopes that this case study can guide other similar efforts. PMID:27501466

Acute coagulopathy of trauma: balancing progressive catecholamine induced endothelial activation and damage by fluid phase anticoagulation.

PubMed

Johansson, P I; Ostrowski, S R

2010-12-01

Acute coagulopathy of trauma predicts a poor clinical outcome. Tissue trauma activates the sympathoadrenal system resulting in high circulating levels of catecholamines that influence hemostasis dose-dependently through immediate effects on the two major compartments of hemostasis, i.e., the circulating blood and the vascular endothelium. There appears to be a dose-dependency with regards to injury severity and the hemostatic response to trauma evaluated in whole blood by viscoelastic assays like thrombelastography (TEG), changing from normal to hypercoagulable, to hypocoagulable and finally hyperfibrinolytic in severely injured patients. Since high catecholamine levels may directly damage the endothelium and thereby promote systemic coagulation activation, we hypothesize that the progressive hypocoagulability and ultimate hyperfibrinolysis observed in whole blood with increasing injury severity, is an evolutionary developed response that counterbalances the injury and catecholamine induced endothelial activation and damage. Given this, the rise in circulating catecholamines in trauma patients may favor a switch from hyper- to hypocoagulability in the blood to keep the progressively more procoagulant microvasculature open. The hypothesis delineated in the present paper thus infers that the state of the fluid phase, including its cellular elements, is a consequence of the degree of the tissue injury and importantly, critically related to the degree of endothelial damage, with a progressively more procoagulant endothelium inducing a gradient of increasing anticoagulation towards the fluid phase. The implications of this hypothesis may include targeted treatment strategies according to the degree of sympathoadrenal response as evaluated by whole blood viscoelastical hemostatic assays in trauma patients.

Cognitive-affective mechanisms related to the maintenance of smoking among trauma-exposed individuals are largely unknown. Cross-sectional data from trauma-exposed treatment-seeking smokers (n = 283) were utilized to test a series of multiple mediator models of trauma exposure and smoking, as mediated by the sequential effects of negative affect and affect-modulation smoking motives. The sequential effects of both mediators indirectly predicted the effect of greater trauma exposure types on nicotine dependence, a biochemical index of smoking, perceived barriers to smoking cessation, and greater withdrawal-related problems during past quit attempts. Negative affect and affect-modulation motives for smoking may contribute to the trauma-smoking association.

The German DRG (diagnosis-related groups) system has been modified and updated into version 2008. For orthopedic and trauma surgery significant changes concerning coding of diagnoses, medical procedures and the DRG structure were made. The modified version has been analyzed in order to ascertain whether the DRG system is suitably qualified to fulfill the demands of the reimbursement system or whether further improvements are necessary. Analysis of the severity of relevant side-effect diagnoses, medical procedures and G-DRGs in the versions 2007 and 2008 was carried out based on the publications of the German DRG institute (InEK) and the German Institute of Medical Documentation and Information (DIMDI). Changes for 2008 focused on the development of DRG structure, DRG validation and codes for medical procedures. The outcome of these changes for German hospitals may vary depending on the range of activities. G-DRG system has become even more complex and the new regulations have also resulted in new problems associated with complications.. High demands are made on correct and complete coding of complex orthopedic and trauma surgery cases. Quality of case allocation within the G-DRG system has been improved. Nevertheless, further improvements of the G-DRG system are necessary, especially for cases with severe injuries.

According to the World Health Organization, over one million people die annually from traffic crashes, in which over half are pedestrians, bicycle riders and two-wheel motor vehicles. In Israel, during the last decade, mortality from traffic crashes has decreased from 636 in 1998 to 288 in 2011. Professionals attribute the decrease in mortality to enforcement, improved infrastructure and roads and behavioral changes among road users, while no credit is given to the trauma system. Trauma systems which care for severe and critical casualties improve the injury outcomes and reduce mortality among road casualties. 1) To evaluate the contribution of the Israeli Health System, especially the trauma system, on the reduction in mortality among traffic casualties. 2) To evaluate the chance of survival among hospitalized traffic casualties, according to age, gender, injury severity and type of road user. A retrospective study based on the National Trauma Registry, 1998-2011, including hospitalization data from eight hospitals. During the study period, the Trauma Registry included 262,947 hospitalized trauma patients, of which 25.3% were due to a road accident. During the study period, a 25% reduction in traffic related mortality was reported, from 3.6% in 1998 to 2.7% in 2011. Among severe and critical (ISS 16+) casualties the reduction in mortality rates was even more significant, 41%; from 18.6% in 1998 to 11.0% in 2011. Among severe and critical pedestrian injuries, a 44% decrease was reported (from 29.1% in 1998 to 16.2% in 2011) and a 65% reduction among bicycle injuries. During the study period, the risk of mortality decreased by over 50% from 1998 to 2011 (OR 0.44 95% 0.33-0.59. In addition, a simulation was conducted to determine the impact of the trauma system on mortality of hospitalized road casualties. Presuming that the mortality rate remained constant at 18.6% and without any improvement in the trauma system, in 2011 there would have been 182 in-hospital deaths compared to the actual 108 traffic related deaths. A 41% difference was noted between the actual number of deaths and the expected number. This study clearly shows that without any improvement in the health system, specifically the trauma system, the number of traffic deaths would be considerably greater. Although the health system has a significant contribution on reducing mortality, it does not receive the appropriate acknowledgment or resources for its proportion in the fight against traffic accidents.

Acute Stress Symptoms in Seriously Injured Patients: Precipitating Versus Cumulative Trauma and the Contribution of Peritraumatic Distress.

2017-08-01

The relationship between type of trauma exposure, cumulative trauma, peritraumatic distress, and subsequent acute stress disorder (ASD) symptoms was examined prospectively in 96 individuals presenting with acute medical injuries to a Level 1 emergency/trauma department. Common precipitating traumas included motor vehicle-related events, stabbings, shootings, and physical assaults. At 2 to 3 weeks follow-up, 22.9% of participants had developed ASD. Univariate analysis revealed no relationship between type of precipitating trauma and ASD symptoms, whereas robust path analysis indicated direct effects of gender, lifetime cumulative trauma exposure, and peritraumatic distress. Peritraumatic distress did not mediate the association between cumulative trauma and symptoms, but did mediate the association between gender and symptomatology. These results, which account for 23.1% of the variance in ASD symptoms, suggest that ASD may be more due to cumulative trauma exposure than the nature of the precipitating trauma, but that cumulative trauma does not exert its primary effect by increasing peritraumatic distress to the most recent trauma.

Trauma is a leading cause of death in patients under the age of 45 and generally associated with a high kinetic energy event such as a motor vehicle accident or fall from extreme elevations. Blunt trauma can affect every organ system and major vascular structure with potentially devastating effect. When we consider abdominal solid organ injury from blunt trauma, we usually think of the liver, spleen, and kidneys. However, all of the abdominal organs, including the pancreas and adrenal glands, may be involved. Blunt hepatic trauma is more commonly associated with venous bleeding rather than arterial injury. Stable venous injury is often managed conservatively; when the patient is hemodynamically unstable from venous hepatic injury, operative management should be first-line therapy. When the injury is arterial, endovascular therapy should be initiated. Blunt trauma to the spleen is the most common cause of traumatic injury to the spleen. Management is controversial. In our institution unstable patients are taken to the operating room, and stable patients with Grades IV-V injuries and patients with active arterial injury are taken for endovascular treatment. Renal injuries are less common, and evidence of arterial injury such as active extravasation or pseudoaneurysm is warranted before endovascular therapy. Pancreatic trauma is uncommon and usually secondary to steering wheel/handlebar mechanism injuries. Adrenal injuries are rare in the absence of megatrauma or underlying adrenal abnormality.

Early life stress may have a lasting impact on the developmental programming of the dopamine (DA) system implicated in psychosis. Early adversity could promote resilience by calibrating the prefrontal stress-regulatory dopaminergic neurotransmission to improve the individual’s fit with the predicted stressful environment. Aberrant reactivity to such match between proximal and distal environments may, however, enhance psychosis disease risk. We explored the combined effects of childhood adversity and adult stress by exposing 12 unmedicated individuals with a diagnosis of non-affective psychotic disorder (NAPD) and 12 healthy controls (HC) to psychosocial stress during an [18F]fallypride positron emission tomography. Childhood trauma divided into early (ages 0–11 years) and late (12–18 years) was assessed retrospectively using a questionnaire. A significant group x childhood trauma interaction on the spatial extent of stress-related [18F]fallypride displacement was observed in the mPFC for early (b = -8.45, t(1,23) = -3.35, p = .004) and late childhood trauma (b = -7.86, t(1,23) = -2.48, p = .023). In healthy individuals, the spatial extent of mPFC DA activity under acute psychosocial stress was positively associated with the severity of early (b = 7.23, t(11) = 3.06, p = .016) as well as late childhood trauma (b = -7.86, t(1,23) = -2.48, p = .023). Additionally, a trend-level main effect of early childhood trauma on subjective stress response emerged within this group (b = -.7, t(11) = -2, p = .07), where higher early trauma correlated with lower subjective stress response to the task. In the NAPD group, childhood trauma was not associated with the spatial extent of the tracer displacement in mPFC (b = -1.22, t(11) = -0.67), nor was there a main effect of trauma on the subjective perception of stress within this group (b = .004, t(11) = .01, p = .99). These findings reveal a potential mechanism of neuroadaptation of prefrontal DA transmission to early life stress and suggest its role in resilience and vulnerability to psychosis. PMID:27007554

Early estimation of mortality risk in patients with trauma is essential. In this study, we evaluate the validity of the Emergency Trauma Score (EMTRAS) and Rapid Emergency Medicine Score (REMS) for predicting in-hospital mortality in patients with trauma. Furthermore, we compared the REMS and the EMTRAS with 2 other scoring systems: the Revised Trauma Score (RTS) and Injury Severity score (ISS).We performed a retrospective chart review of 6905 patients with trauma reported between July 2011 and June 2016 at a large national university hospital in South Korea. We analyzed the associations between patient characteristics, treatment course, and injury severity scoring systems (ISS, RTS, EMTRAS, and REMS) with in-hospital mortality. Discriminating power was compared between scoring systems using the areas under the curve (AUC) of receiver operating characteristic (ROC) curves.The overall in-hospital mortality rate was 3.1%. Higher EMTRAS and REMS scores were associated with hospital mortality (P < .001). The ROC curve demonstrated adequate discrimination (AUC = 0.957 for EMTRAS and 0.9 for REMS). After performing AUC analysis followed by Bonferroni correction for multiple comparisons, EMTRAS was significantly superior to REMS and ISS in predicting in-hospital mortality (P < .001), but not significantly different from the RTS (P = .057). The other scoring systems were not significantly different from each other.The EMTRAS and the REMS are simple, accurate predictors of in-hospital mortality in patients with trauma.

Various injury severity scores exist for trauma; it is known that they do not correlate accurately to military injuries. A promising anatomical scoring system for blast pelvic and perineal injury led to the development of an improved scoring system using machine-learning techniques. An unbiased genetic algorithm selected optimal anatomical and physiological parameters from 118 military cases. A Naïve Bayesian model was built using the proposed parameters to predict the probability of survival. Ten-fold cross validation was employed to evaluate its performance. Our model significantly out-performed Injury Severity Score (ISS), Trauma ISS, New ISS, and the Revised Trauma Score in virtually all areas; positive predictive value 0.8941, specificity 0.9027, accuracy 0.9056, and area under curve 0.9059. A two-sample t test showed that the predictive performance of the proposed scoring system was significantly better than the other systems (p < 0.001). With limited resources and the simplest of Bayesian methodologies, we have demonstrated that the Naïve Bayesian model performed significantly better in virtually all areas assessed by current scoring systems used for trauma. This is encouraging and highlights that more can be done to improve trauma systems not only for our military injured, but also for civilian trauma victims.

There is growing recognition of the relationship between trauma, posttraumatic stress disorder (PTSD) and psychosis. There may be overlaps in causal mechanisms involved in the development of PTSD and psychosis following traumatic or adverse events. Trauma-focussed treatments found to be effective in treating PTSD may therefore represent a new direction in the psychological treatment of psychosis. This systematic review examined the literature on trauma-focussed treatments conducted with people with schizophrenia spectrum or psychotic disorders to determine effects on psychotic symptoms. Secondary outcomes were symptoms of PTSD, depression and anxiety. Twenty-five studies were included in the review, with 12 being included in the meta-analysis. Trauma-focussed treatments had a small, significant effect (g=0.31, CI [0.55, 0.06]) on positive symptoms immediately post-treatment, but the significance and magnitude of this effect was not maintained at follow-up (g=0.18, CI [0.42, -0.06]). Trauma-focussed treatments also had a small effect on delusions at both post-treatment (g=0.37, CI [0.87, -0.12]) and follow-up (g=0.38, CI [0.67, 0.10]), but this only reached significance at follow-up. Effects on hallucinations and negative symptoms were small and non-significant. Effects on PTSD symptoms were also small (post-treatment g=0.21, CI [0.70, -0.27], follow up g=0.31, CI [0.62, 0.00]) and only met significance at follow-up. No significant effects were found on symptoms of depression and anxiety. Results show promising effects of trauma-focussed treatments for the positive symptoms of psychosis, however further studies developing and evaluating trauma-focussed treatments for trauma-related psychotic symptoms are needed.

Brain edema and the associated increase in intracranial pressure are major consequences of traumatic brain injury (TBI) that accounts for most early deaths after TBI. We recently showed that acute severe trauma to cultured astrocytes results in cell swelling. We further examined whether trauma induces cell swelling in neurons and microglia. We found that severe trauma also caused cell swelling in cultured neurons, whereas no swelling was observed in microglia. While severe trauma caused cell swelling in both astrocytes and neurons, mild trauma to astrocytes, neurons, and microglia failed to cell swelling. Since extracellular levels of glutamate are increased in brain post-TBI and microglia are known to release cytokine, and direct exposure of astrocytes to these molecules are known to stimulate cell swelling, we examined whether glutamate or cytokines have any additive effect on trauma-induced cell swelling. Exposure of cultured astrocytes to trauma caused cell swelling, and such swelling was potentiated by the exposure of traumatized astrocytes to glutamate and cytokines. Conditioned medium (CM) from traumatized astrocytes had no effect on neuronal swelling post-trauma, while CM from traumatized neurons and microglia potentiated the effect of trauma on astrocyte swelling. Further, trauma significantly increased the Na-K-Cl co-transporter (NKCC) activity in neurons, and that inhibition of NKCC activity diminished the trauma-induced neuronal swelling. Our results indicate that a differential sensitivity to trauma-induced cell swelling exists in neural cells and that neurons and microglia are likely to be involved in the potentiation of the astrocyte swelling post-trauma.

Trauma centers need objective feedback on performance to inform quality improvement efforts. The Trauma Quality Improvement Program recently published recommended methodology for case mix adjustment and benchmarking performance. We tested the feasibility of applying this methodology to develop risk-adjusted mortality models for a statewide trauma system. We performed a retrospective cohort study of patients ≥16 years old at Pennsylvania trauma centers from 2011 to 2013 (n = 100,278). Our main outcome measure was observed-to-expected mortality ratios (overall and within blunt, penetrating, multisystem, isolated head, and geriatric subgroups). Patient demographic variables, physiology, mechanism of injury, transfer status, injury severity, and pre-existing conditions were included as predictor variables. The statistical model had excellent discrimination (area under the curve = 0.94). Funnel plots of observed-to-expected identified five centers with lower than expected mortality and two centers with higher than expected mortality. No centers were outliers for management of penetrating trauma, but five centers had lower and three had higher than expected mortality for blunt trauma. It is feasible to use Trauma Quality Improvement Program methodology to develop risk-adjusted models for statewide trauma systems. Even with smaller numbers of trauma centers that are available in national datasets, it is possible to identify high and low outliers in performance. PMID:28541852

The Marine Resiliency Study-II examined changes in symptomatology across a deployment cycle to Afghanistan. U.S. Servicemembers (N = 1041) received clinical testing at two time points either bracketing a deployment (855) or not (186). Factor analyses were used to generate summary and change scores from Time 1 to Time 2. A between-subject design was used to examine changes across the deployment cycle with deployment (low-trauma, high-trauma, and non-deployed) and social support (low vs. high) as the grouping variables. Insomnia increased post-deployment regardless of deployment trauma (std. effect for high-trauma and low-trauma = 0.39 and 0.26, respectively). Only the high-trauma group showed increased PTSD symptoms and non-perspective-taking (std. effect = 0.40 and 0.30, respectively), while low-trauma showed decreased anxiety symptoms after deployment (std. effect = -0.17). These associations also depend on social support, with std. effects ranging from -0.22 to 0.51. When the groups were compared, the high-trauma deployed group showed significantly worse PTSD and non-perspective-taking than all other groups. Similar to studies in other military divisions, increased clinical symptoms were associated with high deployment stress in active duty Servicemembers, and social support shows promise as a moderator of said association.

Individuals who experience one type of trauma often experience other types, yet few studies have examined the clustering of trauma. This study examines the clustering of traumatic events and associations of trauma with risk for single and co-occurring major depressive disorder (MDD) and panic attack for 20 years after first trauma. Lifetime histories of MDD, panic attack, and traumatic events were obtained from participants in an Australian twin sample. Latent class analysis was used to derive trauma classes based on each respondent's trauma history. Associations of the resulting classes and of parental alcohol problems and familial effects with risk for a first onset of single and co-occurring MDD and panic attack were examined from the year of first trauma to 20 years later. Traumatic events clustered into three distinct classes characterized by endorsement of little or no trauma, primarily nonassaultive, and primarily assaultive events. Individuals in the assaultive class were characterized by a younger age at first trauma, a greater number of traumatic events, and high rates of parental alcohol problems. Members of the assaultive trauma class had the strongest and most enduring risk for single and co-occurring lifetime MDD and panic attack. Assaultive trauma outweighed associations of familial effects and nonassaultive trauma with risk for 10 years following first trauma.

The treatment of severely injured patients in the trauma resuscitation unit (TRU) requires an interdisciplinary and highly professional trauma team approach. The complete team needs to be waiting for the patient in the TRU on arrival. Treating severely injured patients in the TRU, the trauma team connects the initial preclinical emergency stabilization with the subsequent sophisticated treatment. Thus, the trauma team depends on concise information from the emergency personnel at the scene to provide its leader with further information as well as an accurate alarm including all departments necessary to stabilize the patient in the TRU. Aiming at an accurate and most efficient trauma team alarm, this study was designed to provide and analyze an alarm system which mobilizes the trauma team in a stepwise fashion depending on the pattern of injuries and the threat to life. The trauma team alarm system was analyzed in a prospective data acquisition at a level I trauma center over a period of 12 months. Evaluation followed the acquisition phase and provided comparison to the status prior to the establishment of the alarm system. All items underwent statistical testing using t‑tests (p < 0.05). The data of 775 TRU patients showed a significant reduction of false information on the patients status prior to arrival. It also showed an increase in punctual arrival in the TRU of the emergency teams. False alarms were significantly reduced (from 11.9% to 2.7%, p > 0.01). The duration from arrival of the patient in the TRU to the initial multislice computed tomography (CT) scan was reduced by 6 min while the total period of treatment in the TRU was reduced by 17 min. After the alarm system to gradually mobilize the trauma team was put into action, team members left the TRU if unneeded prior to finishing the initial treatment in only 4% of the cases. The patient fatality rate was 8.8% (injury severity score, ISS = 23 points) after establishment of the alarm system compared to 12.9% (ISS = 25 points) before. The implementation of an accurate and patient status-based alarm system to mobilize the trauma team can improve the quality of treatment while the duration of treatment of the severely injured patients in the TRU can be decreased. It also provides a most efficient mobilization of personnel resources while sustaining patient safety.

Studies to identify an ideal trauma score tool representing prediction of outcomes of the pediatric fall patient remains elusive. Our study was undertaken to identify better predictor of mortality in the pediatric fall patients. Data was retrieved from prospectively maintained trauma registry project at level 1 trauma center developed as part of Multicentric Project-Towards Improving Trauma Care Outcomes (TITCO) in India. Single center data retrieved from a prospectively maintained trauma registry at a level 1 trauma center, New Delhi, for a period ranging from 1 October 2013 to 17 February 2015 was evaluated. Standard anatomic scores Injury Severity Score (ISS) and New Injury Severity Score (NISS) were compared with physiologic score Revised Trauma Score (RTS) using receiver operating curve (ROC). Heart rate and RTS had a statistical difference among the survivors to nonsurvivors. ISS, NISS, and RTS were having 50, 50, and 86% of area under the curve on ROCs, and RTS was statistically significant among them. Physiologically based trauma score systems (RTS) are much better predictors of inhospital mortality in comparison to anatomical based scoring systems (ISS and NISS) for unintentional pediatric falls.

Background Regionalized trauma care improves outcomes; however access to care is not uniform across the US. The objective was to evaluate whether geographic distribution of trauma centers correlates with injury mortality across state trauma systems. Methods Level I/II trauma centers in the contiguous US were mapped. State-level age-adjusted injury fatality rates/100,000people were obtained and evaluated for spatial autocorrelation. Nearest neighbor ratios (NNR) were generated for each state. A NNR<1 indicates clustering, while NNR>1 indicates dispersion. NNR were tested for difference from random geographic distribution. Fatality rates and NNR were examined for correlation. Fatality rates were compared between states with trauma center clustering versus dispersion. Trauma center distribution and population density were evaluated. Spatial-lag regression determined the association between fatality rate and NNR, controlling for state-level demographics, population density, injury severity, trauma system resources, and socioeconomic factors. Results Fatality rates were spatially autocorrelated (Moran's I=0.35, p<0.01). Nine states had a clustered pattern (median NNR 0.55, IQR 0.48–0.60), 22 had a dispersed pattern (median NNR 2.00, IQR 1.68–3.99), and 10 had a random pattern (median NNR 0.90, IQR 0.85–1.00) of trauma center distribution. Fatality rate and NNR were correlated (ρ=0.34, p=0.03). Clustered states had a lower median injury fatality rate compared to dispersed states (56.9 [IQR 46.5–58.9] versus 64.9 [IQR 52.5–77.1], p=0.04). Dispersed compared to clustered states had more counties without a trauma center that had higher population density than counties with a trauma center (5.7% versus 1.2%, p<0.01). Spatial-lag regression demonstrated fatality rates increased 0.02/100,000persons for each unit increase in NNR (p<0.01). Conclusions Geographic distribution of trauma centers correlates with injury mortality, with more clustered state trauma centers associated with lower fatality rates. This may be a result of access relative to population density. These results may have implications for trauma system planning and requires further study to investigate underlying mechanisms PMID:26517780

Minimal acceptable care as a vital component to Missouri's trauma system.

Helling, Thomas S

2002-07-01

Immediate attention to life-threatening injuries and expeditious transfer of major and complex wounds to tertiary care trauma centers are the cornerstones of any trauma system. Rapid assessment and "minimalization" of care should be the buzz-word of rural (Level III) and suburban (Level II) trauma centers in order to provide quickest treatment of injuries by timely referral of patients for definitive attention. This concept is called minimal acceptable care and may serve to improve patient outcome by reducing the interval to ultimate treatment and avoidance of duplication of services.

Children and youth who have experienced foster care or orphanage-rearing have often experienced complex developmental trauma, demonstrating an interactive set of psychological and behavioral issues. Trust-Based Relational Intervention (TBRI) is a therapeutic model that trains caregivers to provide effective support and treatment for at-risk children. TBRI has been applied in orphanages, courts, residential treatment facilities, group homes, foster and adoptive homes, churches, and schools. It has been used effectively with children and youth of all ages and all risk levels. This article provides the research base for TBRI and examples of how it is applied. PMID:24453385

Policymakers frequently face the need to increase funding in isolated and frequently heterogeneous (clinically and in terms of resource consumption) patient subpopulations. This article presents a methodologic solution for testing the appropriateness of using existing grouping and weighting methodologies for funding subsets of patients in the scenario where a case-mix approach is preferable to a flat-rate based payment system. Using as an example the subpopulation of trauma cases of Ontario lead trauma hospitals, the statistical techniques of linear and nonlinear regression models, regression trees, and spline models were applied to examine the fit of the existing case-mix groups and reference weights for the trauma cases. The analyses demonstrated that for funding Ontario trauma cases, the existing case-mix systems can form the basis for rational and equitable hospital funding, decreasing the need to develop a different grouper for this subset of patients. This study confirmed that Injury Severity Score is a poor predictor of costs for trauma patients. Although our analysis used the Canadian case-mix classification system and cost weights, the demonstrated concept of using existing case-mix systems to develop funding rates for specific subsets of patient populations may be applicable internationally.

The mortality risk from motor vehicle injuries in California has increased during the last decade.

Organized trauma systems and trauma centers are thought to improve trauma outcomes. It is clear that injured patients who receive care in trauma centers have survival advantages. However, large regions of California still do not have access to trauma centers. Many injured patients in California continue to receive their care in nontrauma center hospitals. The purpose of this study was to compare outcomes in California counties with and without trauma centers. In addition, we wished to query the efficacy of the current statewide trauma system by asking whether mortality after motor vehicle trauma in California has improved during the last decade. We performed a retrospective outcome study. The California highway patrol provided data from all motor vehicle crashes (MVCs) and mortality during the years 1999 to 2008 for the 58 counties in California. Percent fatality was calculated as the number of motor vehicle fatalities divided by the number of injuries. Data were analyzed to compare outcomes in counties with and without trauma centers. Furthermore, demographic data were studied to analyze the relationship of population and hospital density on mortality. Mortality was significantly lower in counties with trauma centers. Low population and hospital density independently correlated with increased mortality. Injury mortality rates after MVCs increased during the decade both in counties with and without trauma centers. Overall, the presence of a trauma center improved the chances of survival after an MVC in California counties. However, mortality rates after injuries increased during the decade both in counties with and without trauma centers. Future efforts to improve outcomes for injured patients in California will require new approaches, which must include improving both access to trauma centers and the care provided in nontrauma center hospitals.

In 2015, the American College of Surgeons Committee on Trauma convened a consensus conference to develop the Needs-Based Assessment of Trauma Systems (NBATS) tool to assist in determining the number of trauma centers required for a region. We tested the performance of NBATS with respect to the optimal number of trauma centers needed by region in California. Trauma center data were obtained from the California Emergency Services Authority Information Systems (CEMSIS). Numbers of admitted trauma patients (ISS > 15) were obtained using statewide nonpublic admissions data from the California Office of Statewide Health Planning and Development (OSHPD), CEMSIS, and data from local emergency medical service agency (LEMSA) directors who agreed to participate in a telephone survey. Population estimates per county for 2014 were obtained from the U.S. Census. NBATS criteria used included population, transport time, community support, and number of discharges for severely injured patients (ISS > 15) at nontrauma centers and trauma centers. Estimates for the number of trauma centers per region were created for each of the three data sources and compared to the number of existing centers. A total of 62 state-designated trauma centers were identified for California: 13 (21%) Level I, 36 (58%) Level II, and 13 (11%) Level III. NBATS estimates for the total number of trauma centers in California were 27% to 47% lower compared to the number of trauma centers in existence, but this varied based on urban/rural status. NBATS estimates were lower than the current state in 70% of urban areas but were higher in almost 90% of rural areas. All data sources (OSHPD, CEMSIS, local data) produced similar results. Estimates from the NBATS tool are different from what is currently in existence in California, and differences exist based on whether the region is rural or urban. Findings from the current study can help inform future iterations of the NBATS tool. Economic, level V.

Developmental Timing of Trauma Exposure Relative to Puberty and the Nature of Psychopathology Among Adolescent Girls.

Marshall, Amy D

2016-01-01

Increased neuroplasticity and neural development during puberty provide a context for which stress and trauma can have dramatic and long-lasting effects on psychological systems; therefore, this study was designed to determine whether exposure to potentially traumatic events during puberty uniquely predicts adolescent girls' psychopathology. Because neural substrates associated with different forms of psychopathology seemingly develop at different rates, the possibility that the developmental timing of trauma relative to puberty predicts the nature of psychopathology (posttraumatic stress disorder [PTSD], depressive, and anxiety disorders) was examined. A subset of 2,899 adolescent girls from the National Comorbidity Survey Replication-Adolescent Supplement who completed the study 2+ years postmenarche was selected. Past-year psychiatric disorders and reports of age of trauma exposure were assessed using the Composite International Diagnostic Interview. Developmental stages were defined as the 2 years after the year of menarche ("postpuberty"), 3 years before and year of menarche ("puberty"), 2 to 6 years before the puberty period ("grade school"), and 4 to 5 years after birth ("infancy-preschool"). Compared to other developmental periods, trauma during puberty conferred significantly more risk (50.47% of model R(2)) for girls' past-year anxiety disorder diagnoses (primarily social phobia), whereas trauma during the grade school period conferred significantly more risk (47.24% of model R(2)) for past-year depressive disorder diagnoses. Recency of trauma best predicted past-year PTSD diagnoses. Supporting rodent models, puberty may be a sensitive period for the impact of trauma on girls' development of an anxiety disorder. Trauma prepuberty or postpuberty distinctly predicts depression or PTSD, suggesting differential etiological processes. Copyright © 2016 American Academy of Child and Adolescent Psychiatry.

birth trauma has become an increasingly recognised maternal mental health issue and has important implications for both mother and infant. The importance of subjective birth experience in the development of birth trauma has been identified and may mediate the lack of theoretical consistency in this area. The current study aims to explore the subjective experience of birth trauma among first time mothers in Ireland. It aims to separate the potential effects of peripartum depression (PPD) from this in limiting this qualitative investigation to women who reported birth trauma, without PPD. mixed methods: Quantitative methods facilitated the recruitment of participants, the selection of a homogenous sample and addressed previous methodological flaws in birth trauma research. Interpretative Phenomenological Analysis (IPA) was used to explore the subjective experience of traumatic childbirth. seven, first- time mothers who reported a traumatic childbirth, without significant symptoms of PPD participated. screening measures of birth trauma and PPD were completed by participants. A semi-structured interview was then conducted with each participant about their childbirth experience. Interviews were transcribed and analysed using IPA. The primary superordinate theme recounted how the identity and individuality of women is ignored and discounted, throughout the process of childbirth. Identity is challenged and altered as a result of women's incompatibility with the maternity system. this study supports the existence of birth trauma in an Irish context and highlights the subjective experience of women as central to the development of birth trauma. acknowledgement and inclusion of the mother as an individual throughout the process of childbirth may be protective in limiting the experience of birth trauma.

Beta-adrenoreceptor blocker (beta-blocker) therapy may improve outcomes in surgical patients by decreasing cardiac oxygen consumption and hypermetabolism. Because beta-blockers can lower the systemic blood pressure and cerebral perfusion pressure, there is concern regarding their use in patients with head injury. However, beta-blockers may protect beta-receptor rich brain cells by attenuating cerebral oxygen consumption and metabolism. We hypothesized that beta-blockers are safe in trauma patients, even if they have suffered a significant head injury. Using pharmacy and trauma registry data of a Level I trauma center, we identified a cohort of trauma patients who received beta-blockers during their hospital stay (beta-cohort). Trauma admissions who did not receive beta-blockers were in the control cohort. beta-blocker status, in combination with other variables associated with mortality, were placed in a stepwise multivariate logistic regression to identify independent predictors of fatal outcome. In all, 303 (7%) of 4,117 trauma patients received beta-blockers. In the beta-cohort, 45% of patients were on beta-blockers preinjury. The most common reason to initiate beta-blocker therapy was blood pressure (60%) and heart rate (20%) control. The overall mortality rate was 5.6% and head injury was considered to be the major cause of death. After adjusting for age, Injury Severity Scale score, blood pressure, Glasgow Coma Scale score, respiratory status, and mechanism of injury, the odds ratio for fatal outcome was 0.3 (p < 0.001) for beta-cohort as compared with control. Decreased risk of fatal outcome was more pronounced in patients with a significant head injury. beta-blocker therapy is safe and may be beneficial in selected trauma patients with or without head injury. Further studies looking at beta-blocker therapy in trauma patients and their effect on cerebral metabolism are warranted.

Bipolar electrocautery is an effective and commonly used haemostatic technique but it may also cause iatrogenic brain trauma due to thermal injury and secondary inflammatory reactions. Progesterone has anti-inflammatory and neuroprotective actions in traumatic brain injury. However, its potential use in preventing iatrogenic brain trauma has not been explored. We conducted a pilot animal study to investigate the effect of systemic progesterone on brain cellular responses to electrocautery-induced injury. Adult male Sprague-Dawley rats received standardized bipolar electrocautery (40 W for 2 seconds) over the right cerebral cortex. The treatment group received progesterone intraperitoneally 2 hours prior to surgery; the control group received the drug vehicle only. Immunohistochemical studies showed that progesterone could significantly reduce astrocytic hypertrophy on postoperative day 1, 3 and 7, as well as macrophage infiltration on day 3. The number of astrocytes, however, was unaffected. Our findings suggest that progesterone should be further explored as a neuroprotective agent against electrocautery-induced or other forms of iatrogenic trauma during routine neurosurgical procedures. Future studies may focus on different dosing regimens, neuronal survival, functional outcome, and to compare progesterone with other agents such as dexamethasone. Copyright © 2013 Elsevier Ltd.

This article describes the "relational systems change" model developed by the Institute for Health and Recovery, and the implementation of the model in Massachusetts from 1998-2002 to facilitate systems change to support the delivery of integrated and trauma-informed services for women with co-occurring substance abuse and mental health disorders and histories of violence and empirical evidence of resulting systems changes. The federally funded Women Embracing Life and Living (WELL) Project utilized relational strategies to facilitate systems change within and across 3 systems levels: local treatment providers, community (or region), and state. The WELL Project demonstrates that a highly collaborative, inclusive, and facilitated change process can effect services integration within agencies (intra-agency), strengthen integration within a regional network of agencies (interagency), and foster state support for services integration.

The relational model of trauma (Scheeringa & Zeanah, 2001) proposes that infants' trauma symptoms may be influenced by their mothers' trauma symptoms and disruptions in caregiving behavior, although the mechanisms by which this occurs are less well understood. In this research, we examined the direct and indirect effects of a traumatic event (maternal intimate partner violence [IPV]), maternal trauma symptoms, and impaired (harsh and neglectful) parenting on infant trauma symptoms in a sample of mother-infant dyads (N=182) using structural equation modeling. Mothers completed questionnaires on IPV experienced during pregnancy and the child's first year of life, their past-month trauma symptoms, their child's past-month trauma symptoms, and their parenting behaviors. Results indicated that the effects of prenatal IPV on infant trauma symptoms were partially mediated by maternal trauma symptoms, and the relationship between maternal and infant trauma symptoms was fully mediated by neglectful parenting. Postnatal IPV did not affect maternal or infant trauma symptoms. Findings support the application of the relational model to IPV-exposed mother-infant dyads, with regard to IPV experienced during pregnancy, and help identify potential foci of intervention for professionals working with mothers and children.

Massive injury remains the most common cause of death for productive age group globally. The current immune, inflammatory paradigm, based on an incomplete understanding of the functional integration of the complex host response, remains a major impediment to the development of effective innovative diagnostic and therapeutic effort. This study attempt to investigate the pattern of inflammatory and anti-inflammatory cytokines such as interleukin-6 and 10 (IL-6 and IL-10) and their interaction in severe injury condition with its major complication as multiple organ dysfunction syndrome (MODS) and failure (MOF) after polytrauma. This is multicenter study held at 4 academic Level-1 Trauma center included 54 polytrauma participants. Inclusion criteria were age between 16-60 years old, had new acute episode of polytrauma which defined as injury in ≥2 body region with Injury Severity Score (ISS) ≥16, and the presence of Systemic Inflammation Response Syndrome (SIRS). Serum level of IL-6 and IL-10 were taken on day 2, 3, and 5 after trauma. During hospitalization, samples were observed for the occurrence of MODS or MOF using Sequential Organ Failure Assessment (SOFA) and mortality rate were also noted. Participant were mostly male with mean of age of 35, 9 years old, endured polytrauma caused by traffic accident. Elevation of cytokines (IL-6, IL-10, and IL-6/IL-10 ratio) had directly proportional with MODS and mortality. Threshold level of compensation for severe trauma is IL-6 of 50 pg/mL and trauma load of ISS ≥30. Inflammation reaction greater than this threshold level would result in downhill level of IL-6, IL-10, or IL-6/IL-10 ratio which associated with poor outcome (MODS and death). The elevation of these cytokines level were represent as compensation/adaptive immune system and its fall represent decompensating/failure of immune system after severe trauma. The pattern of IL-6 and IL-10 after polytrauma represent immune system effort to restore homeostasis. Besides cytokines interaction, there must be other factors that contribute to mortality and poor outcome after major trauma. Further study is needed to investigate genomic variant or polymorphism related to trauma.

Trauma, Delinquency, and Substance Use: Co-occurring Problems for Adolescent Girls in the Juvenile Justice System.

Smith, Dana K; Saldana, Lisa

2013-07-02

Girls in the juvenile justice system are known to have high rates of co-occurring childhood abuse, trauma, and substance abuse. Girls with this constellation of problems are at high risk for serious adverse outcomes, including problems with drug dependence and abuse. The relationship between childhood sexual abuse, childhood physical abuse, other types of childhood trauma, and rates of substance use during adolescence were examined for girls in the juvenile justice system. As expected, childhood sexual abuse was significantly related to girls' substance use during adolescence. In contrast to prior research, no link was found between physical abuse, lifetime trauma, and substance use. Limitations and future directions are discussed.

Children who have experienced early adversities are at risk for behavioral problems and trauma symptoms. Using a two-group, pre–post intervention design, the authors evaluated the effectiveness of an online parent training for Trust-Based Relational Intervention, a trauma-informed, attachment-based intervention, in reducing behavioral problems and trauma symptoms in at-risk adopted children. Children of parents in the treatment group (n = 48) demonstrated significant decreases in behavioral problems and trauma symptoms after intervention. Scores for children in a matched-sample control group did not change. Findings suggest this intervention can effectively reduce behavioral problems and trauma symptoms in children with histories of adversities. PMID:26072917

Both traumatic deployment experiences and antecedent traumas increase personnel's risk of developing PTSD and depression. However, only cross-sectional studies have assessed whether antecedent trauma moderates stress reactions to deployment experiences. This study prospectively examines whether antecedent trauma moderates the association between deployment trauma and post-deployment PTSD and depressive symptoms after accounting for antecedent mental health problems, in a large Australian Defence Force (ADF) sample. In the ADF Middle East Area of Operations Prospective Study, currently-serving military personnel deployed to Afghanistan across 2010-2012 (n = 1122) completed self-reported measures at pre-deployment and post-deployment. Within multivariable regressions, associations between deployment trauma and PTSD and depressive symptoms at post-deployment were stronger for personnel with greater antecedent trauma. However, once adjusting for antecedent mental health problems, these significant interaction effects disappeared. Instead, deployment-related trauma and antecedent mental health problems showed direct associations with post-deployment mental health problems. Antecedent trauma was also indirectly associated with post-deployment mental health problems through antecedent mental health problems. Similar associations were seen with prior combat exposure as a moderator. Antecedent and deployment trauma were reported retrospectively. Self-reports may also suffer from social desirability bias, especially at pre-deployment. Our main effects results support the pervasive and cumulative negative effect of trauma on military personnel, regardless of its source. While antecedent trauma does not amplify personnel's psychological response to deployment trauma, it is indirectly associated with increased post-deployment mental health problems. Antecedent mental health should be considered within pre-deployment prevention programs, and deployment-trauma within post-operational screening. Copyright © 2017. Published by Elsevier B.V.

The aim of this study was to identify and assess the effects of changes in the Lithuanian trauma service from 2007 to 2012. We postulate that the implications derived from this study will be of importance to trauma policy planners and makers in Lithuania and throughout other countries of Eastern and Central Europe. Out of 10,390 trauma admissions to four trauma centers in 2007, 294 patients (2.8%) were randomly selected for the first arm of a representative study sample. Similarly, of 9918 trauma admissions in 2012, 250 (2.5%) were randomly chosen for comparison in the study arm. Only cases with a diagnosis falling into the ICD-10 "S" and "T" codes were included. A survey of whom regarding changes in quality of trauma care from 2007 to 2012 was carried out by emergency medical service (EMS) providers. The Revised Trauma Score (RTS) mean value was 7.45±1.04 for the 2007 year arm; it was 7.53±0.93 for the 2012 year arm (P=0.33). Mean time from the moment of a call from the site of the traumatic event to the patient's arrival at the trauma center did not differ between the arms of the sample: 49.95min in 2007 vs. 51.6min in 2012 (P=0.81). An application of the operational procedures such as a cervical spine protection using a hard collar, oxygen therapy, infusion of intravenous fluids, and pain relief on the trauma scene was more frequent in 2012 than in 2007. Management of trauma patients in the emergency department improved regarding the availability of 24/7 computed tomography scanner facilities and an on-site radiographer. Time to CT-scanning was reduced by 38.8%, and time to decision-making was reduced by 16.5% in 2012. Changes in operational procedures in the Lithuanian pre-hospital care provision and management of trauma patients in emergency departments of trauma centers improved the efficiency of trauma care delivery over the 2007-2012 period.

Estimate the effectiveness of brief interventions in reducing trauma recidivism in hospitalized trauma patients who screened positive for alcohol and/or illicit drug use. Dynamic cohort study based on registry data from 1818 patients included in a screening and brief intervention program for alcohol and illicit drug use for hospitalized trauma patients. Three subcohorts emerged from the data analysis: patients who screened negative, those who screened positive and were offered brief intervention, and those who screened positive and were not offered brief intervention. Follow-up lasted from 10 to 52 months. Trauma-free survival, adjusted hazard rate ratios (aHRR) and adjusted incidence rate ratios (aIRR) were calculated, and complier average causal effect (CACE) analysis was used. We found a higher cumulative risk of trauma recidivism in the subcohort who screened positive. In this subcohort, an aHRR of 0.63 (95% CI: 0.41-0.95) was obtained for the group offered brief intervention compared to the group not offered intervention. CACE analysis yielded an estimated 52% reduction in trauma recidivism associated with the brief intervention. The brief intervention offered during hospitalization in trauma patients positive for alcohol and/or illicit drug use can halve the incidence of trauma recidivism.

Acute and long-term behavioral correlates of underwater trauma--potential relevance to stress and post-stress syndromes.

PubMed

Richter-Levin, G

1998-06-02

As a consequence of a brief but significantly extreme stressor, an individual will experience a stress response, which may sometimes develop into Acute Stress Disorder (ASD) or Post-Traumatic Stress Disorder (PTSD). Though a rat model for ASD and PTSD is not expected to encompass the richness and complexity of the disorders in humans, it will enable the study of the common underlying mechanisms that generate the disorders, the study of pre-trauma etiological aspects of the disorders and the screening of drugs with potential relevance to the treatment of the disorders. One well-documented aspect of PTSD is the enhancing influence of contextual elements on the appearance of symptoms of the post-stress trauma. To exploit this effect, we have chosen to assess the effects of an underwater trauma in the Morris water maze since the effects of such trauma on memory and attention can be later evaluated in the context of the trauma. At both 1 h and 3 weeks after the trauma, significant behavioral deficits were observed in the water maze. The effects of the underwater trauma on the performance of rats in the water maze were context specific. Underwater trauma in a different (out-of-context) water container had no effects on the ability of rats to perform a spatial memory task in the water maze. An elevated level of anxiety was found in the plus maze test, independently of whether the trauma was performed in the water maze or in a different (out-of-context) water container. The results indicate that a within-context underwater trauma has both acute and lasting behavioral consequences which can be assessed using a spatial memory test in the context of the trauma. The results are discussed in relation to their relevance to stress and PTSD.

Delinquent-Victim Youth-Adapting a Trauma-Informed Approach for the Juvenile Justice System.

Rapp, Lisa

2016-01-01

The connection between victimization and later delinquency is well established and most youth involved with the juvenile justice system have at least one if not multiple victimizations in their history. Poly-victimized youth or those presenting with complex trauma require specialized assessment and services to prevent deleterious emotional, physical, and social life consequences. Empirical studies have provided information which can guide practitioners work with these youth and families, yet many of the policies and practices of the juvenile justice system are counter to this model. Many youth-serving organizations are beginning to review their operations to better match a trauma-informed approach and in this article the author will highlight how a trauma-informed care model could be utilized to adapt the juvenile justice system.

Injury rates and injury mortality rates are generally higher in rural and remote communities compared with urban jurisdictions as has been shown to be the case in the rural-remote area of Northwest (NW) British Columbia (BC). The purpose of study was to identify: (1) the place and timing of death following injury in NW BC, (2) access to and quality of local trauma services, and (3) opportunities to improve trauma outcomes. Quantitative data from demographic and geographic databases, the BC Trauma Registry, Hospital discharge abstract database, and the BC Coroner's Office, along with qualitative data from chart reviews of selected major trauma cases, and interviews with front-line trauma care providers were collated and analyzed for patients sustaining injury in NW BC from April 2001 to March 2006. The majority of trauma deaths (82%) in NW BC occur prehospital. Patients arriving alive to NW hospitals have low hospital mortality (1.0%), and patients transferring from NW BC to tertiary centers have better outcomes than matched patients achieving direct entry into the tertiary center by way of geographic proximity. Access to local trauma services was compromised by: incident discovery, limited phone service (land lines/cell), incomplete 911 emergency medical services system access, geographical and climate challenges compounded by limited transportation options, airport capabilities and paramedic training level, dysfunctional hospital no-refusal policies, lack of a hospital destination policies, and lack of system leadership and coordination. Improving trauma outcomes in this rural-remote jurisdiction requires a systems approach to address root causes of delays in access to care, focusing on improved access to emergency medical services, hospital bypass and destination protocols, improved transportation options, advanced life support transfer capability, and designated, coordinated local trauma services.

2014-01-01

This case report describes historical trauma on a rural American Indian reservation and outlines participatory action approaches for nurses. The prevalence of historical trauma often goes unnoticed by healthcare professionals because of its multifaceted nature and subsequent lack of provider understanding. Nurses accustomed to looking only for physical and psychosocial signs of trauma may not specifically understand how to align significant historical trauma events with prevention, education, and healthcare delivery. Nursing interventions developed through participatory action and directed at individual, family, and community levels of care are most effective in treating and preventing cumulative effects of historical trauma.

Prehospital emergency care in Singapore has taken shape over almost a century. What began as a hospital-based ambulance service intended to ferry medical cases was later complemented by an ambulance service under the Singapore Fire Brigade to transport trauma cases. The two ambulance services would later combine and come under the Singapore Civil Defence Force. The development of prehospital care systems in island city-state Singapore faces unique challenges as a result of its land area and population density. This article defines aspects of prehospital trauma care in Singapore. It outlines key historical milestones and current initiatives in service, training, and research. It makes propositions for the future direction of trauma care in Singapore. The progress Singapore has made given her circumstances may serve as lessons for the future development of prehospital trauma systems in similar environments.

Training-induced muscle, skeletal and joint trauma may result in acute phase response reflected by the changes in the blood concentration of serum amyloid A (SAA) in racehorses. It remains yet unclear if such systemic reaction could be triggered by sport injuries and what is the impact of different types of musculoskeletal trauma on SAA concentrations in racehorses. This study aimed to determine changes in the SAA blood concentration in racehorses with different types of injuries of musculoskeletal system. The study involved 28 racehorses diagnosed after the race with bone fractures (n = 7), dorsal metacarpal disease (n = 11), joint trauma (n = 4) or tendon and muscle trauma (n = 6) and 28 healthy control racehorses. Serum samples were collected twice, between 1 and 4 days of the injury or succesful completion of the race. SAA concentration was measured using the commercial ELISA kit. Differences between mean SAA concentration in respective groups were analyzed using ANOVA and Tukey post-hoc test. Mean SAA concentration within the first 4 days of the injury of muscle and tendon was significantly higher than in bone fractures, dorsal metacarpal disease, joint trauma or in the healthy horses (p<0,001). There were no significant differences between the other groups. Strain injuries of muscle and tendons can cause a moderate increase in SAA blood concentration in racehorses, reflecting the occurrence of the acute phase response. Similar reaction is not observed in the stress-related bone injuries.

Somatic experiencing: using interoception and proprioception as core elements of trauma therapy

PubMed Central

Payne, Peter; Levine, Peter A.; Crane-Godreau, Mardi A.

2015-01-01

Here we present a theory of human trauma and chronic stress, based on the practice of Somatic Experiencing® (SE), a form of trauma therapy that emphasizes guiding the client's attention to interoceptive, kinesthetic, and proprioceptive experience. SE™ claims that this style of inner attention, in addition to the use of kinesthetic and interoceptive imagery, can lead to the resolution of symptoms resulting from chronic and traumatic stress. This is accomplished through the completion of thwarted, biologically based, self-protective and defensive responses, and the discharge and regulation of excess autonomic arousal. We present this theory through a composite case study of SE treatment; based on this example, we offer a possible neurophysiological rationale for the mechanisms involved, including a theory of trauma and chronic stress as a functional dysregulation of the complex dynamical system formed by the subcortical autonomic, limbic, motor and arousal systems, which we term the core response network (CRN). We demonstrate how the methods of SE help restore functionality to the CRN, and we emphasize the importance of taking into account the instinctive, bodily based protective reactions when dealing with stress and trauma, as well as the effectiveness of using attention to interoceptive, proprioceptive and kinesthetic sensation as a therapeutic tool. Finally, we point out that SE and similar somatic approaches offer a supplement to cognitive and exposure therapies, and that mechanisms similar to those discussed in the paper may also be involved in the benefits of meditation and other somatic practices.

Chronic occupational stress exposure may increase the vulnerability to acoustic trauma in military professionals.

Mălina, Ciumaşu-Rimbu

Today little is known about the connection between chronic stress exposure and hearing loss. These effects cannot be explained by differences in HPA axis response but recent studies saying that chronic stress induced limbic system alterations spread to nonlimbic areas affecting auditory system might be the key. On the other hand we know that subjects exposed to chronic stress may prove hypersensitivity to novel stressors. The aim of this study is to confirm that occupational chronic stress (OCS) exposure determines vulnerability to acoustic trauma and to establish a method to identify individuals at risk prior to their exposure to high intensity acoustic stimulus. 60 military personnel with known acoustic trauma injury evidentiated through audiograms and occupational chronic stress exposure quantified through validated questionnaires were exposed to mild novel stressor: occupational medicine evaluation and clinically assessed for maladaptive cardiovascular response (MCVR). Employees were split in two groups, group 1 (MCVR) and group 2 (non MCVR). We found positive correlation between level of perceived OCS and level of hearing loss on entire group and between groups with values of parameters significantly higher in group 1. Subjects exposed to OCS with hypersensitivity to novel stressor evidentiated through maladaptive cardiovascular stress response may be more vulnerable to high intensity acoustic stimulus and consequently acoustic trauma. Establishing methods and biomarkers that help us indentify individuals at risk of developing acoustic trauma might decrease the high burden of hearing loss.

This virtual reality study tested the effect of childhood trauma on level of paranoid ideations and distress in response to social stress, in interaction with psychosis liability and level of social stress exposure. Seventy-five individuals with higher psychosis liability (55 with recent onset psychotic disorder and 20 at ultra-high risk for psychosis) and 95 individuals with lower psychosis liability (42 siblings and 53 controls) were exposed to a virtual café in five experiments with 0-3 social stressors (crowded, other ethnicity and hostility). Paranoid ideation was measured after each experiment. Subjective distress was self-rated before and after experiments. Multilevel random regression analyses were used to test main effects of childhood trauma and interaction effects. Childhood trauma was more prevalent in individuals with higher psychosis liability, and was associated with higher level of (subclinical) psychotic and affective symptoms. Individuals with a history of childhood trauma responded with more subjective distress to virtual social stress exposures. The effects of childhood trauma on paranoia and subjective distress were significantly stronger when the number of virtual environmental stressors increased. Higher psychosis liability increased the effect of childhood trauma on peak subjective distress and stress reactivity during experiments. Childhood trauma is associated with heightened social stress sensitivity and may contribute to psychotic and affective dysregulation later in life, through a sensitized paranoid and stress response to social stressors.

A number of studies suggest that a history of trauma, depression, and posttraumatic stress disorder (PTSD) are associated with autobiographical memory deficits, notably overgeneral memory (OGM). However, whether there are any group differences in the nature and magnitude of OGM has not been evaluated. Thus, a meta-analysis was conducted to quantify group differences in OGM. The effect sizes were pooled from studies examining the effect on OGM from a history of trauma (e.g., childhood sexual abuse), and the presence of PTSD or current depression (e.g., major depressive disorder). Using multiple search engines, 13 trauma studies and 12 depression studies were included in this review. A depression effect was observed on OGM with a large effect size, and was more evident by the lack of specific memories, especially to positive cues. An effect of trauma history on OGM was observed with a medium effect size, and this was most evident by the presence of overgeneral responses to negative cues. The results also suggested an amplified memory deficit in the presence of PTSD. That is, the effect sizes of OGM among individuals with PTSD were very large and relatively equal across different types of OGM. Future studies that directly compare the differences of OGM among 4 samples (i.e., controls, current depression without trauma history, trauma history without depression, and trauma history and depression) would be warranted to verify the current findings.

Severe injury results in increased mobilization of hematopoietic progenitor cells (HPC) from the bone marrow (BM) to sites of injury, which may contribute to persistent BM dysfunction after trauma. Norepinephrine is a known inducer of HPC mobilization, and nonselective β-blockade with propranolol has been shown to decrease mobilization after trauma and hemorrhagic shock (HS). This study will determine the role of selective β-adrenergic receptor blockade in HPC mobilization in a combined model of lung contusion (LC) and HS. Male Sprague-Dawley rats were subjected to LC, followed by 45 minutes of HS. Animals were then randomized to receive atenolol (LCHS + β1B), butoxamine (LCHS + β2B), or SR59230A (LCHS + β3B) immediately after resuscitation and daily for 6 days. Control groups were composed of naive animals. BM cellularity, %HPCs in peripheral blood, and plasma granulocyte-colony stimulating factor levels were assessed at 3 hours and 7 days. Systemic plasma-mediated effects were evaluated in vitro by assessment of BM HPC growth. Injured lung tissue was graded histologically by a blinded reader. The use of β2B or β3B following LCHS restored BM cellularity and significantly decreased HPC mobilization. In contrast, β1B had no effect on HPC mobilization. Only β3B significantly reduced plasma G-CSF levels. When evaluating the plasma systemic effects, both β2B and β3B significantly improved BM HPC growth as compared with LCHS alone. The use of β2 and β3 blockade did not affect lung injury scores. Both β2 and β3 blockade can prevent excess HPC mobilization and BM dysfunction when given after trauma and HS, and the effects seem to be mediated systemically, without adverse effects on subsequent healing. Only treatment with β3 blockade reduced plasma G-CSF levels, suggesting different mechanisms for adrenergic-induced G-CSF release and mobilization of HPCs. This study adds to the evidence that therapeutic strategies that reduce the exaggerated sympathetic stimulation after severe injury are beneficial and reduce BM dysfunction.

The timely administration of analgesics is crucial to the comprehensive management of trauma patients. When an emergency department (ED) pharmacist participates in trauma resuscitation, the pharmacist acts as a medication resource for trauma team members and facilitates the timely administration of analgesics. This study measured the impact of a pharmacist on time to first analgesic dose administered during trauma resuscitation. All adult (>18 years) patients who presented to this level II trauma center via activation of the trauma response system between January 1, 2009, and May 31, 2013, were screened for eligibility. For inclusion, patients must have received intravenous fentanyl, morphine, or hydromorphone in the trauma bay. The time to medication administration was defined as the elapsed time from ED arrival to administration of first analgesic. There were 1328 trauma response system activations during the study period; of which 340 patients were included. The most common analgesic administered was fentanyl (62% in both groups). When a pharmacist was participating, the mean time to first analgesic administered was decreased (17 vs 21 minutes; P = .03). Among the 78% of patients with documented pain scores, the overall mean reduction in pain scores from ED arrival to ED discharge was similar between the 2 groups. There was a 2.4 point reduction with a pharmacist versus 2.7 without a pharmacist, using a 0 to 10 numeric pain rating scale. The participation of a clinical pharmacist during trauma resuscitation significantly decreased the time to first analgesic administration in trauma patients. The results of this study supplement the literature supporting the integration of clinical ED pharmacists on trauma teams.

The Hong Kong Special Administrative Region (HKSAR) of the People's Republic of China (PRC) has seen significant changes in its trauma service over the last ten years including the implementation of a regional trauma system. The author's institution is one of the five trauma centres designated in 2003. This article reports our initial clinical experience. A prospective single-centre trauma registry from January 2004 to December 2008 was reviewed. The primary clinical outcome measure was hospital mortality. The Trauma and Injury Severity Score (TRISS) methodology was used for bench-marking with the North America Major Trauma Outcome Study (MTOS) database. There were 1451 patients. The majority (83.9%) suffered from blunt injury. The overall mortality rate was 7.8%. Severe injury, defined as the Injury Severity Score > 15, occurred in 22.5% of patients, and was associated with a mortality rate of 31.6%. A trend of progressive improvement was noted. The M-statistic was 0.99, indicating comparable case-mix with the MTOS. The Z- and W-statistics of each individual year revealed fewer, but not significantly so, number of survivors than expected. Trauma centre designation was feasible in the HKSAR and was associated with a gradual improvement in patient care. Trauma system implementation may be considered in regions equipped with the necessary socio-economic and organizational set-up.

Study Objective: To examine the effect of sleep deprivation compared to sleep, immediately after experimental trauma stimuli on the development of intrusive memories to that trauma stimuli. Design: Participants were exposed to a film with traumatic content (trauma film). The immediate response to the trauma film was assessed, followed by either total sleep deprivation (sleep deprived group, N = 20) or sleep as usual (sleep group, N = 22). Twelve hours after the film viewing the initial psychological effect of the trauma film was measured and for the subsequent 6 days intrusive emotional memories related to the trauma film were recorded in daily life. Setting: Academic sleep laboratory and participants' home environment. Participants: Healthy paid volunteers. Measurements and results: On the first day after the trauma film, the psychological effect as assessed by the Impact of Event Scale – Revised was lower in the sleep deprived group compared to the sleep group. In addition, the sleep deprived group reported fewer intrusive emotional memories (mean 2.28, standard deviation [SD] 2.91) compared to the sleep group (mean 3.76, SD 3.35). Because habitual sleep/circadian patterns, psychological health, and immediate effect of the trauma film were similar at baseline for participants of both groups, the results cannot be accounted for by pre-existing inequalities between groups. Conclusions: Our findings suggest that sleep deprivation on one night, rather than sleeping, reduces emotional effect and intrusive memories following exposure to experimental trauma.

Assessment of the effects and limitations of the 1998 to 2008 Abbreviated Injury Scale map using a large population-based dataset.

Trauma systems should consistently monitor a given trauma population over a period of time. The Abbreviated Injury Scale (AIS) and derived scores such as the Injury Severity Score (ISS) are commonly used to quantify injury severities in trauma registries. To reflect contemporary trauma management and treatment, the most recent version of the AIS (AIS08) contains many codes which differ in severity from their equivalents in the earlier 1998 version (AIS98). Consequently, the adoption of AIS08 may impede comparisons between data coded using different AIS versions. It may also affect the number of patients classified as major trauma. The entire AIS98-coded injury dataset of a large population based trauma registry was retrieved and mapped to AIS08 using the currently available AIS98-AIS08 dictionary map. The percentage of codes which had increased or decreased in severity, or could not be mapped, was examined in conjunction with the effect of these changes to the calculated ISS. The potential for free text information accompanying AIS coding to improve the quality of AIS mapping was explored. A total of 128280 AIS98-coded injuries were evaluated in 32134 patients, 15471 patients of whom were classified as major trauma. Although only 4.5% of dictionary codes decreased in severity from AIS98 to AIS08, this represented almost 13% of injuries in the registry. In 4.9% of patients, no injuries could be mapped. ISS was potentially unreliable in one-third of patients, as they had at least one AIS98 code which could not be mapped. Using AIS08, the number of patients classified as major trauma decreased by between 17.3% and 30.3%. Evaluation of free text descriptions for some injuries demonstrated the potential to improve mapping between AIS versions. Converting AIS98-coded data to AIS08 results in a significant decrease in the number of patients classified as major trauma. Many AIS98 codes are missing from the existing AIS map, and across a trauma population the AIS08 dataset estimates which it produces are of insufficient quality to be used in practice. However, it may be possible to improve AIS98 to AIS08 mapping to the point where it is useful to established registries.

Trauma events are four times more prevalent in inmates than in the general public and are associated with increased recidivism and other mental and physical health issues. To evaluate the effects of Transcendental Meditation (TM) on trauma symptoms in male inmates. One hundred eighty-one inmates with a moderate- to high-risk criminal profile were randomly assigned to either the TM program or to a usual care control group. The Trauma Symptom Checklist and the Perceived Stress Scale were administered at baseline and four-month posttest. Significant reductions in total trauma symptoms, anxiety, depression, dissociation, and sleep disturbance subscales, and perceived stress in the TM group were found compared with controls (all p values < 0.001). The high-trauma subgroup analysis further showed a higher magnitude of effects in the TM group compared with controls on all outcomes, with Cohen effect sizes ranging from 0.67 to 0.89. Results are consistent with those of prior studies of the TM program in other populations and its effects on trauma symptoms and perceived stress.

For cardio-pulmonary resuscitation there are standardized treatment concepts, but there have been few prospective investigations examining the efficacy of prehospital advanced trauma life support and its effect on the outcome in patients with severe head injury and multiple trauma treated within the German emergency system. The results of this study underline the importance of intensive prehospital treatment and highlight some problems that should be taken into account in future in the training of emergency physicians. METHODS. A total of 179 patients with cerebral trauma were investigated. Data obtained included demographic and logistic data of the patients and the emergency physicians, diagnoses and treatment at the scene of the accident and state of the patient on admission in each case. Having divided the patients into three groups by severity of the trauma, we distinguished between sufficient and insufficient treatment and assessed infusion therapy, ventilatory support, positioning and immobilization, and analgesic and sedative therapy. For statistical analysis of the data we used chi 2-test and Fisher's exact test. P < 0.05 was considered significant. RESULTS. There were 102 patients who had sustained a cerebral trauma without other life-threatening lesions (score 1), 40 with multiple trauma (score 2) and 37 with multiple trauma (score 3). On average 2.4 IV lines were established and the patients received 1186 +/- 765 cc of crystalloid in addition to 801 +/- 411 cc of colloid fluids. In all groups, patients who received adequate infusion therapy had a better outcome; even in the group with score 1 significantly fewer had a fatal outcome. In all, 167 (93%) patients had endotracheal tubes placed, and in 150 cases (84%) ventilatory therapy was considered sufficient. The proportion of score 1 patients with sufficient ventilatory support who had a fatal outcome was significantly lower than that in the group with insufficient treatment. In patients with multiple trauma we could not separate the benefits of sufficient respiratory therapy and infusion therapy. In only 54% of the cases a vacuum mattress was used and in only 41% the patients were positioned with the upper part of the body elevated by 30 degrees. These were 28 patients (16%) who received neither analgesics nor sedatives. Regardless of the quality of prehospital treatment of isolated head injury, a Glasgow Coma Scale (GCS) score lower than 5 involved a very high mortality and all patients with a GCS score of 9 or more survived. In the group with GCS scores between 5 and 8, however, significantly more of the patients who received adequate treatment survived (82.5% vs 40%). CONCLUSIONS. The present study confirms that sufficient advanced trauma life support can improve the outcome of trauma victims with cerebral trauma. Adequate infusion and respiratory therapy reduce the mortality among such patients significantly. In patients with multiple trauma a clear positive effect of generous infusion therapy also is evident. The clearest effect of sufficient prehospital treatment is seen in patients with isolated cerebral trauma and a GCS score between 5 and 8. These results demonstrate the importance of advanced trauma life support and show emphatically that the so-called scoop-and-run strategy should be abandoned when resources are available for extended preclinical emergency treatment. On the other hand, we detected some problem areas in the prehospital treatment of trauma victims, such as positioning, immobilization and drug therapy with analgesics and sedatives. These findings allow us to pinpoint specific points that should be stressed in the training of emergency physicians and paramedics.

Global disparities in trauma care contribute to significant morbidity and mortality (M&M) in low- and middle-income countries. Implementation of quality improvement (QI) programs has been shown to be a cost-effective strategy to improve trauma care quality. In this study, we aim to characterize the trauma QI programs in a broad range of low- to high-income countries in the Americas to assess areas for targeted improvement in global trauma QI efforts. We conducted a mixed methods survey of trauma care providers in North and South America distributed in-person at trauma care conferences and online via a secure survey platform. Responses were analyzed to observe differences across respondent country income categories. One hundred ninety-two surveys were collected, representing 21 different countries from three income strata (three lower-middle-, eleven upper-middle-, and eight high-income countries). Respondents were primarily physicians or physicians-in-training (85%). Eighty-nine percent of respondents worked at an institution where M&M conferences occurred. M&M conferences were significantly more frequent at higher income levels (P = 0.002), as was attending physician presence at M&M conferences (70% in high-income countries versus 43% in lower-middle-income countries). There were also significant differences in the structure, quality, and follow-up of M&M conferences in lower versus higher income countries. Sixty-three percent of respondents reported observing some kind of positive change at their institution due to M&M conferences. The survey also suggested significantly higher utilization of autopsy (P < 0.001) and electronic trauma registries (P = 0.01) at higher income levels. This survey demonstrated an encouraging pattern of widespread adoption of trauma QI programs in several countries in North and South America. However, there continue to be significant disparities in the structure and function of trauma QI efforts in low- and middle-income countries in the Americas. There are several potential areas for development and improvement of trauma care systems, including standardization of case selection and follow-up for M&M conferences and increased use of medical literature to improve evidence-based care.

Shatz, D V; Zhang, C; McGrath, M

1999-12-01

As a method of crime reduction among teenagers, several cities, counties, and states across the country have enacted, or attempted to enact, curfew laws. A curfew law was successfully implemented in Dade County, Florida, in January of 1996. Although its efficacy for crime reduction has been questioned, its benefit for trauma prevention may be real. Trauma registry data was collected retrospectively and prospectively from Dade County's Level I trauma center for all trauma victims 5 to 16 years of age. The time period spanned the 2 years before the institution of the curfew law (January 1, 1996) and the 2 years after. Total adult and pediatric trauma volumes during the 4-year period were used as comparisons, as well as juvenile traumas occurring during noncurfew hours. Total trauma volume did not change significantly across the 4-year period, nor did the volume among the curfew age group during noncurfew hours. The predominant mechanisms of injury during curfew hours were motor vehicle crashes and gunshots. Neither the patterns of mechanisms nor ages changed significantly during the precurfew and postcurfew eras. However, the volume of cases seen at the trauma center among the curfew age group was significantly lower with the curfew law in effect (mean, 7.0/month) than before it was in effect (mean, 9.5/month, p = 0.043). Although the overall trauma admissions and juvenile trauma admissions during the noncurfew hours remained relatively stable, juvenile trauma admissions during curfew hours dropped significantly in the 2 years after enforcement of the curfew law compared with the 2 years before the curfew law. This finding suggests that attempts to prevent late-night nonproductive street presence among teens can decrease the incidence of trauma occurrences.

Helicopter Emergency Medical Services (HEMS) are highly resource-intensive facilities that are well established as part of trauma systems in many high-income countries. We evaluated the cost-effectiveness of a physician-staffed HEMS intervention in combination with treatment at a major trauma centre versus ground ambulance or indirect transport (via a referral hospital) in New South Wales (NSW), Australia. Cost and effectiveness estimates were derived from a cohort of trauma patients arriving at St George Hospital in NSW, Australia during an 11-year period. Adjusted estimates of in-hospital mortality were derived using logistic regression and adjusted hospital costs were estimated through a general linear model incorporating a gamma distribution and log link. These estimates along with other assumptions were incorporated into a Markov model with an annual cycle length to estimate a cost per life saved and a cost per life-year saved at one year and over a patient's lifetime respectively in three patient groups (all patients; patients with serious injury [Injury Severity Score>12]; patients with traumatic brain injury [TBI]). Results showed HEMS to be more costly but more effective at reducing in-hospital mortality leading to a cost per life saved of $1,566,379, $533,781 and $519,787 in all patients, patients with serious injury and patients with TBI respectively. When modelled over a patient's lifetime, the improved mortality associated with HEMS led to a cost per life year saved of $96,524, $50,035 and $49,159 in the three patient groups respectively. Sensitivity analyses revealed a higher probability of HEMS being cost-effective in patients with serious injury and TBI. Our investigation confirms a HEMS intervention is associated with improved mortality in trauma patients, especially in patients with serious injury and TBI. The improved benefit of HEMS in patients with serious injury and TBI leads to improved estimated cost-effectiveness. Copyright © 2012 Elsevier Ltd. All rights reserved.

Most trauma surgeons are unfamiliar with screening, brief intervention, and referral (SBIR) programs for substance use disorders, and few trauma centers provide them. This report describes how an urban private-teaching hospital adapted a protocol from an existing emergency department-based program to include patients treated by the trauma service. We recorded the rates of SBIR completion and reasons for failure during each phase of the implementation, interviewed trauma service staff and health educators to assess attitudes toward the program, and evaluated patient satisfaction surveys. By adding SBIR staff to the trauma outpatient clinic and to trauma morning rounds, the capture rate increased from 12 to 71%. Most screened patients (59%) were found at risk for problems or probably dependent on alcohol or drugs. Trauma service staff and health educators reported high satisfaction with the program. Patients reported higher satisfaction with SBIR. SBIR services can be effectively integrated into all components of a busy, urban trauma service by adding specially trained health educators to the trauma service staff. This collaboration provides effective SBIR services to both trauma and emergency service patients without interfering with patient flow or medical procedures. The relatively high percentage of patients at risk for alcohol or drug problems supports the inclusion of routine alcohol and drug screening for all eligible trauma patients.

Measuring trauma center injury prevention activity: an assessment and reporting tool.

To develop an assessment and reporting tool for a trauma center's community partnership strategy to deliver injury prevention programs in a large metropolitan area. The tool was designed to track prevention activity and serve as a reporting format for the parent health system, county designating agency, and the American College of Surgeons' Trauma Center Verification Process. The tool collected data including trauma center paid and volunteer personnel time, equipment, resource, and financial costs, community group and public agency contributions, number of community members receiving prevention material or presentations, impact on public policy, and print and broadcast media coverage. These measurements were incorporated in a reporting grid format. Six youth injury prevention programs were evaluated over a recent 2-year interval to demonstrate the tool's usefulness. Of six programs, three focused on motor vehicle injuries, one on teen suicide, one on firearm injuries, and one on drug and alcohol abuse. Trauma Center personnel asset allocation included 3% full-time equivalent by the Trauma Medical Director, 30% by the Injury Prevention and Community Outreach Coordinator, and 473 person hours (both work and volunteer) by physicians, nurses, and other personnel. Trauma Center equipment and fixed asset expenses totaled $3,950 and monetary contribution totaled $4,430. Community groups and public agencies contributed 20,400 person hours with estimated in-kind costs exceeding $750,000. Five of the six programs continued during the 2-year period. A gun-lock giveaway program was suspended because of a product recall. A total of over 29,000 youth received prevention material and presentations. Four public policy initiatives and 18 Trauma Center media stories with over 50 mentions and 37 new community partnerships resulted. The reports generated were easily incorporated in the trauma center's reports to local and national organizations and agencies. This assessment tool provided a detailed but concise accounting of trauma center injury prevention activity. The reports generated were effective in displaying the center's work.

The adverse impact of obesity has been extensively studied in the general population; however, the added risk of obesity on trauma-related mortality remains controversial. This study investigated and compared mortality as well injury patterns and length of stay (LOS) in obese and normal-weight patients hospitalized for trauma in the hospital and intensive care unit (ICU) of a Level I trauma center in southern Taiwan. Detailed data of 880 obese adult patients with body mass index (BMI) ≥ 30 kg/m(2) and 5391 normal-weight adult patients (25 > BMI ≥ 18.5 kg/m(2)) who had sustained a trauma injury between January 1, 2009 and December 31, 2013 were retrieved from the Trauma Registry System. Pearson's chi-squared, Fisher's exact, and independent Student's t-tests were used to compare differences between groups. Propensity score matching with logistic regression was used to evaluate the effect of obesity on mortality. In this study, obese patients were more often men, motorcycle riders and pedestrians, and had a lower proportion of alcohol intoxication compared to normal-weight patients. Analysis of Abbreviated Injury Scale scores revealed that obese trauma patients presented with a higher rate of injury to the thorax, but a lower rate of facial injuries than normal-weight patients. No significant differences were found between obese and normal-weight patients regarding Injury Severity Score (ISS), Trauma-Injury Severity Score (TRISS), mortality, the proportion of patients admitted to the ICU, or LOS in ICU. After propensity score matching, logistic regression of 66 well-matched pairs did not show a significant influence of obesity on mortality (odds ratio: 1.51, 95% confidence interval: 0.54-4.23 p = 0.438). However, significantly longer hospital LOS (10.6 vs. 9.5 days, respectively, p = 0.044) was observed in obese patients than in normal-weight patients, particularly obese patients with pelvic, tibial, or fibular fractures. Compared to normal-weight patients, obese patients presented with different injury characteristics and bodily injury patterns but no difference in mortality.

Toxicant baiting systems are effective at population suppression against both the Formosan subterranean termite, Coptotermes formosanus Shiraki, and the Eastern subterranean termite, Reticulitermes flavipes (Kollar). However, trap shyness (i.e., station abandonment) is often quoted as a confounding factor affecting their success....

The effect of both a thoracic trauma and a soft-tissue trauma on fracture healing in a rat model

PubMed Central

2011-01-01

Background and purpose There is some clinical evidence that fracture healing is impaired in multiply injured patients. Nothing is known, however, about the effects of various types of injuries and their contribution to a possible disturbance of the fracture-healing process. We investigated the effect of a thoracic trauma and an additional soft-tissue trauma on fracture healing in a rat tibia model. Methods 3 groups of rats were operated: group A with a simple fracture of the tibia and fibula, group B with a fracture and an additional thoracic trauma, and group C with a fracture, thoracic trauma, and an additional soft-tissue trauma. The fracture and the soft-tissue injury were produced by a special guillotine-like device and the thoracic trauma by a blast wave generator. After one day, the serum level of IL-6 was quantified, and at the end of the study (28 days) the mechanical properties and the callus volume of the healed tibia were determined. Results Increasing the severity of the injury caused IL-6 levels to more than double 1 day after injury. It halved the load to failure in mechanical tests and led to reduced callus volume after 28 days of healing. Interpretation Fracture healing is impaired when additional thoracic trauma and soft tissue trauma occurs. PMID:21463222

Measuring long-term disability and functional outcomes after major trauma is not standardized across trauma registries. An ideal measure would be responsive to change but not have significant ceiling effects. The aim of this study was to compare the responsiveness of the Glasgow Outcome Scale (GOS), GOS-Extended (GOSE), Functional Independence Measure (FIM), and modified FIM in major trauma patients, with and without significant head injuries. Patients admitted to two adult Level I trauma centers in Victoria, Australia, who survived to discharge from hospital, were aged 15 years to 80 years with a blunt mechanism of injury, and had an estimated Injury Severity Score >15 on admission, were recruited for this prospective study. The instruments were administered at baseline (hospital discharge) and by telephone interview 6 months after injury. Measures of responsiveness, including effect sizes, were calculated. Bootstrapping techniques, and floor and ceiling effects, were used to compare the measures. Two hundred forty-three patients participated, of which 234 patients (96%) completed the study. The GOSE and GOS were the most responsive instruments in this major trauma population with effect sizes of 5.3 and 4.4, respectively. The GOSE had the lowest ceiling effect (17%). The GOSE was the instrument with greatest responsiveness and the lowest ceiling effect in a major trauma population with and without significant head injuries and is recommended for use by trauma registries for monitoring functional outcomes and benchmarking care. The results of this study do not support the use of the modified FIM for this purpose.

The Role of Communication During Trauma Activations: Investigating the Need for Team and Leader Communication Training.

Raley, Jessica; Meenakshi, Rani; Dent, Daniel; Willis, Ross; Lawson, Karla; Duzinski, Sarah

Fatal errors due to miscommunication among members of trauma teams are 2 to 4 times more likely to occur than in other medical teams, yet most trauma team members do not receive communication effectiveness training. A needs assessment was conducted to examine trauma team members' miscommunication experiences and research scientists' evaluations of live trauma activations. The purpose of this study is to demonstrate that communication training is necessary and highlight specific team communication competencies that trauma teams should learn to improve communication during activations. Data were collected in 2 phases. Phase 1 required participants to complete a series of surveys. Phase 2 included live observations and assessments of pediatric trauma activations using the assessment of pediatric resuscitation team assessments (APRC-TA) and assessment of pediatric resuscitation leader assessments (APRC-LA). Data were collected at a southwestern pediatric hospital. Trauma team members and leaders completed surveys at a meeting and were observed while conducting activations in the trauma bay. Trained research scientists and clinical staff used the APRC-TA and APRC-LA to measure trauma teams' medical performance and communication effectiveness. The sample included 29 healthcare providers who regularly participate in trauma activations. Additionally, 12 live trauma activations were assessed monday to friday from 8am to 5pm. Team members indicated that communication training should focus on offering assistance, delegating duties, accepting feedback, and controlling emotional expressions. Communication scores were not significantly different from medical performance scores. None of the teams were coded as effective medical performance and ineffective team communication and only 1 team was labeled as ineffective leader communication and effective medical performance. Communication training may be necessary for trauma teams and offer a deeper understanding of the communication competencies that should be addressed. The APRC-TA and APRC-LA both include team communication competencies that could be used as a guide to design training for trauma team members and leaders. Researchers should also continue to examine recommendations for improved team and leader communication during activations using in-depth interviews and focus groups.

Trauma Resuscitation Evaluation Times and Correlating Human Patient Simulation Training Differences-What is the Standard?

PubMed

Bonjour, Timothy J; Charny, Grigory; Thaxton, Robert E

2016-11-01

Rapid effective trauma resuscitations (TRs) decrease patient morbidity and mortality. Few studies have evaluated TR care times. Effective time goals and superior human patient simulator (HPS) training can improve patient survivability. The purpose of this study was to compare live TR to HPS resuscitation times to determine mean incremental resuscitation times and ascertain if simulation was educationally equivalent. The study was conducted at San Antonio Military Medical Center, Department of Defense Level I trauma center. This was a prospective observational study measuring incremental step times by trauma teams during trauma and simulation patient resuscitations. Trauma and simulation patient arms had 60 patients for statistical significance. Participants included Emergency Medicine residents and Physician Assistant residents as the trauma team leader. The trauma patient arm revealed a mean evaluation time of 10:33 and simulation arm 10:23. Comparable time characteristics in the airway, intravenous access, blood sample collection, and blood pressure data subsets were seen. TR mean times were similar to the HPS arm subsets demonstrating simulation as an effective educational tool. Effective stepwise approaches, incremental time goals, and superior HPS training can improve patient survivability and improved departmental productivity using TR teams.

Regionalized trauma care improves outcomes; however, access to care is not uniform across the United States. The objective was to evaluate whether geographic distribution of trauma centers correlates with injury mortality across state trauma systems. Level I or II trauma centers in the contiguous United States were mapped. State-level age-adjusted injury fatality rates per 100,000 people were obtained and evaluated for spatial autocorrelation. Nearest neighbor ratios (NNRs) were generated for each state. A NNR less than 1 indicates clustering, while a NNR greater than 1 indicates dispersion. NNRs were tested for difference from random geographic distribution. Fatality rates and NNRs were examined for correlation. Fatality rates were compared between states with trauma center clustering versus dispersion. Trauma center distribution and population density were evaluated. Spatial-lag regression determined the association between fatality rate and NNR, controlling for state-level demographics, population density, injury severity, trauma system resources, and socioeconomic factors. Fatality rates were spatially autocorrelated (Moran's I = 0.35, p < 0.01). Nine states had a clustered pattern (median NNR, 0.55; interquartile range [IQR], 0.48-0.60), 22 had a dispersed pattern (median NNR, 2.00; IQR, 1.68-3.99), and 10 had a random pattern (median NNR, 0.90; IQR, 0.85-1.00) of trauma center distribution. Fatality rate and NNR were correlated (ρ = 0.34, p = 0.03). Clustered states had a lower median injury fatality rate compared with dispersed states (56.9 [IQR, 46.5-58.9] vs. 64.9 [IQR, 52.5-77.1]; p = 0.04). Dispersed compared with clustered states had more counties without a trauma center that had higher population density than counties with a trauma center (5.7% vs. 1.2%, p < 0.01). Spatial-lag regression demonstrated that fatality rates increased by 0.02 per 100,000 persons for each unit increase in NNR (p < 0.01). Geographic distribution of trauma centers correlates with injury mortality, with more clustered state trauma centers associated with lower fatality rates. This may be a result of access relative to population density. These results may have implications for trauma system planning and require further study to investigate underlying mechanisms.

Childhood trauma is a risk factor for psychosis. Deficits in response inhibition are common to psychosis and trauma-exposed populations, and associated brain functions may be affected by trauma exposure in psychotic disorders. We aimed to identify the influence of trauma-exposure on brain activation and functional connectivity during a response inhibition task. We used functional magnetic resonance imaging to examine brain function within regions-of-interest [left and right inferior frontal gyrus (IFG), right dorsolateral prefrontal cortex, right supplementary motor area, right inferior parietal lobule and dorsal anterior cingulate cortex], during the performance of a Go/No-Go Flanker task, in 112 clinical cases with psychotic disorders and 53 healthy controls (HCs). Among the participants, 71 clinical cases and 21 HCs reported significant levels of childhood trauma exposure, while 41 clinical cases and 32 HCs did not. In the absence of effects on response inhibition performance, childhood trauma exposure was associated with increased activation in the left IFG, and increased connectivity between the left IFG seed region and the cerebellum and calcarine sulcus, in both cases and healthy individuals. There was no main effect of psychosis, and no trauma-by-psychosis interaction for any other region-of-interest. Within the clinical sample, the effects of trauma-exposure on the left IFG activation were mediated by symptom severity. Trauma-related increases in activation of the left IFG were not associated with performance differences, or dependent on clinical diagnostic status; increased IFG functionality may represent a compensatory (overactivation) mechanism required to exert adequate inhibitory control of the motor response.

Moderators of differential psychotherapy outcome for posttraumatic stress disorder (PTSD) are rare, yet have crucial clinical importance. We tested the moderating effects of trauma type for three psychotherapies in 110 unmedicated patients with chronic DSM-IV PTSD. Patients were randomized to 14 weeks of prolonged exposure (PE, N = 38), interpersonal psychotherapy (IPT, N = 40), or relaxation therapy (RT, N = 32). The Clinician-Administered PTSD Scale (CAPS) was the primary outcome measure. Moderator candidates were trauma type: interpersonal, sexual, physical. We fit a regression model for week 14 CAPS as a function of treatment (a three-level factor), an indicator of trauma type presence/absence, and their interactions, controlling for baseline CAPS, and evaluated potential confounds. Thirty-nine (35%) patients reported sexual, 68 (62%) physical, and 102 (93%) interpersonal trauma. Baseline CAPS scores did not differ by presence/absence of trauma types. Sexual trauma as PTSD criterion A significantly moderated treatment effect: whereas all therapies had similar efficacy among nonsexually-traumatized patients, IPT had greater efficacy among sexually traumatized patients (efficacy difference with and without sexual trauma: IPT vs. PE and IPT vs. RT P's < .05), specifically in PTSD symptom clusters B and D (P's < .05). Few studies have assessed effects of varying trauma types on effects of differing psychotherapies. In this exploratory study, sexual trauma moderated PTSD outcomes of three therapies: IPT showed greater benefit for sexually traumatized patients than PE or RT. The IPT focuses on affect to help patients determine trust in their current environments may particularly benefit patients who have suffered sexual assault. © 2017 Wiley Periodicals, Inc.

The study aims to compare the trauma care systems in Asian countries. Asian countries were categorised into three groups; 'lower middle-income country', 'upper middle-income country' and 'high-income country'. The Medline/PubMed database was searched for articles published from January 2005 to December 2014 using relevant key words. Articles were excluded if they examined a specific injury mechanism, referred to a specific age group, and/or did not have full text available. We extracted information and variables on pre-hospital and hospital care factors, and regionalised system factors and compared them across countries. A total of 46 articles were identified from 13 countries, including Pakistan, India, Vietnam and Indonesia from lower middle-income countries; the Islamic Republic of Iran, Thailand, China, Malaysia from upper middle-income countries; and Saudi Arabia, the Republic of Korea, Japan, Hong Kong and Singapore from high-income countries. Trauma patients were transported via various methods. In six of the 13 countries, less than 20% of trauma patients were transported by ambulance. Pre-hospital trauma teams primarily comprised emergency medical technicians and paramedics, except in Thailand and China, where they included mainly physicians. In Iran, Pakistan and Vietnam, the proportion of patients who died before reaching hospital exceeded 50%. In only three of the 13 countries was it reported that trauma surgeons were available. In only five of the 13 countries was there a nationwide trauma registry. Trauma care systems were poorly developed and unorganised in most of the selected 13 Asian countries, with the exception of a few highly developed countries. © 2017 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Adolescents are at high risk for violence exposure and initiation of drug use. Co-occurring substance use and trauma exposure are associated with increased risk of mental health disorders, school underachievement, and involvement with multiple systems of care. Coordination and integration of systems of care are of utmost importance for these vulnerable youth. This study delineates the negative sequelae and increased service utilization patterns of adolescents with a history of trauma, substance abuse, and co-occurring trauma and substance abuse to support the need for integrated mental health and substance abuse services for youth. Data from two national sources, the National Child Traumatic Stress Network and Center for Substance Abuse Treatment demonstrate the increased clinical severity (measured by reports of emotional and behavioral problems), dysfunction, and service utilization patterns for youth with co-occurring trauma exposure and substance abuse. We conclude with recommendations for an integrated system of care that includes trauma-informed mental health treatment and substance abuse services aimed at reducing the morbidity and relapse probability of this high-risk group.

The epidemiological data of a given population on spinal trauma in India is lacking. The present study was undertaken to evaluate the profile of patients with thoracolumbar fractures in a tertiary care hospital in an urban setup. Four hundred forty patients with thoracolumbar spinal injuries admitted from January 1990 to May 2000 to the All India Institute of Medical Sciences were included in the analysis. Both retrospective data retrieval and prospective data evaluation of patients were done from January 1998 to May 2000. Epidemiological factors like age, sex and type of injury, mode of transport, time of reporting and number of transfers before admission were recorded. Frankel's grading was used to assess neurological status. Functional assessment of all patients was done using the FIM™ instrument (Functional Independence Measure). Average followup was 33 months (24-41 months). Of the 440 patients, females comprised 17.95% (n=79), while 82.04% (n=361) were males. As many as 40.9% (n=180) of them were in the third decade. Fall from height remained the most common cause (n=230, 52.3%). Two hundred sixty (59.1%) patients reported within 48 hours. Thirty-two (7.27%) patients had single transfer, and all 32 showed complete independence for mobility at final followup. 100 of 260 (38.5%) patients reporting within 48 hours developed pressure sores, while 114 of 142 (80.28%) patients reporting after 5 days developed pressure sores. The present study highlights the magnitude of the problems of our trauma-care and transport system and the difference an effective system can make in the care of spinal injury patients. There is an urgent need for epidemiological data on a larger scale to emphasize the need for a better trauma-care system and pave way for adaptation of well-established trauma-care systems from developed countries.

To evaluate cross-sectional patient distribution and standardised 30-day mortality in the intensive care units (ICU) of an inclusive hub and spoke trauma system. ICUs of the Integrated System for Trauma Patient Care (SIAT) of Emilia-Romagna, an Italian region with a population of approximately 4.5 million. 5300 patients with an Injury Severity Score (ISS) >15 were admitted to the regional ICUs and recorded in the Regional Severe Trauma Registry between 2007 and 2012. Patients were classified by the Abbreviated Injury Score as follows: (1) traumatic brain injury (2) multiple injuriesand (3) extracranial lesions. The SIATs were divided into those with at least one neurosurgical level II trauma centre (TC) and those with a neurosurgical unit in the level I TC only. A higher proportion of patients (out of all SIAT patients) were admitted to the level I TC at the head of the SIAT with no additional neurosurgical facilities (1083/1472, 73.6%) compared with the level I TCs heading SIATs with neurosurgical level II TCs (1905/3815; 49.9%). A similar percentage of patients were admitted to level I TCs (1905/3815; 49.9%) and neurosurgical level II TCs (1702/3815, 44.6%) in the SIATs with neurosurgical level II TCs. Observed versus expected mortality (OE) was not statistically different among the three types of centre with a neurosurgical unit; however, the best mean OE values were observed in the level I TC in the SIAT with no neurosurgical unit. The Hub and Spoke concept was fully applied in the SIAT in which neurosurgical facilities were available in the level I TC only. The performance of this system suggests that competition among level I and level II TCs in the same Trauma System reduces performance in both. The density of neurosurgical centres must be considered by public health system governors before implementing trauma systems. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Protective Effects of Ginkgo biloba Extract EGb 761 against Noise Trauma-Induced Hearing Loss and Tinnitus Development

Korn, Sabine

2014-01-01

Noise-induced hearing loss (NIHL) and resulting comorbidities like subjective tinnitus are common diseases in modern societies. A substance shown to be effective against NIHL in an animal model is the Ginkgo biloba extract EGb 761. Further effects of the extract on the cellular and systemic levels of the nervous system make it a promising candidate not only for protection against NIHL but also for its secondary comorbidities like tinnitus. Following an earlier study we here tested the potential effectiveness of prophylactic EGb 761 treatment against NIHL and tinnitus development in the Mongolian gerbil. We monitored the effects of EGb 761 and noise trauma-induced changes on signal processing within the auditory system by means of behavioral and electrophysiological approaches. We found significantly reduced NIHL and tinnitus development upon EGb 761 application, compared to vehicle treated animals. These protective effects of EGb 761 were correlated with changes in auditory processing, both at peripheral and central levels. We propose a model with two main effects of EGb 761 on auditory processing, first, an increase of auditory brainstem activity leading to an increased thalamic input to the primary auditory cortex (AI) and second, an asymmetric effect on lateral inhibition in AI.

Many trauma patients might be first cared for at nondesignated centers before transfer to a trauma center. Limited research has investigated determinants of timely triage and transfer to identify those amenable to quality improvement. This study explored factors influencing timely triage and transfer in a regional trauma system. Centers (n = 15) with both long and short transfer times (emergency department length of stay before transfer) in Ontario were identified using a regional trauma registry. Physicians and nurses in these centers were interviewed with a view to determining factors that either impeded or enabled rapid decisions regarding the need for transfer to a trauma center. A grounded theory approach and constant comparative technique were used to collect and analyze data. Nineteen physicians and eight nurses participated. Clinician level (experience, training, personality, fear of judgment, nursing role), institutional level (guidelines, continuing education, trauma infrastructure, human resources) and system-level (bed availability, referral center, air transport, communication with trauma centers) factors influenced timely decision making. Participants offered several recommendations to improve care. These included guidelines for transfer, a "no refusal" policy at trauma centers, improved air transport and referral center services, as well as further regionalization. Additional features of hospitals with shorter transfer times included coaching of new staff, team meetings, leadership engagement, sharing of performance data, and minimum work hours for physicians. Numerous interacting factors that may influence trauma triage and transfer were identified. These findings can be used by policy makers, health care managers, and clinicians in emergency departments or trauma centers to evaluate and improve trauma triage and transfer, or plan new services. The findings can also be used by researchers to examine the relevance of these factors in other settings or to implement and evaluate the impact of interventions informed by recommendations generated here.

Effects of psychological and biomechanical trauma on brain and behavior

McAllister, Thomas W.; Stein, Murray B.

2011-01-01

The current conflicts in Iraq and Afghanistan have resulted in a large cohort of military personnel exposed to combat-related psychological trauma as well as biomechanical trauma, including proximity to blast events. Historically, the long-term effects of both types of trauma have been viewed as having different neural substrates, with some controversy over the proper attribution of such symptoms evident after each of the major conflicts of the last century. Recently, great effort has been directed toward distinguishing which neuropsychiatric sequelae are due to which type of trauma. Of interest, however, is that the chronic effects of exposure to either process are associated with a significant overlap in clinical symptoms. Furthermore, similar brain regions are vulnerable to the effects of either psychological or biomechanical trauma, raising the possibility that shared mechanisms may underlie the clinically observed overlap in symptom profile. This paper reviews the literature on the neural substrate of biomechanical and psychological injury and discusses the implications for evaluation and treatment of the neuropsychiatric sequelae of these processes.

Our aim has been to present the functioning of orthopaedic and trauma services in the healthcare system of Serbia. In the introduction, we present geographic, demographic, political and economic elements, which define more closely the position of Serbia in the Southeastern Europe. Further, the healthcare system of Serbia, organized in four levels, is presented: self-care, primary healthcare, secondary healthcare and tertiary healthcare, as well as the schedule of 20,157 physicians engaged in healthcare. In addition, we point out numerous problems, which the system is faced with. Special attention is paid to orthopaedic and trauma services active within the system, its development, current condition and personnel education. We have concluded that, despite this being a middle-income country, the healthcare system is well developed. With 524 orthopaedic surgeons, working in 56 specialized departments, musculoskeletal diseases and trauma management are covered at all three healthcare levels. Nevertheless, the authors also underline weaknesses that are mostly of technical nature. Measures for their elimination and improvement of the entire service are also suggested.

OBJECTIVE Traumatic life histories are highly prevalent in people living with HIV/AIDS (PLWHA) and predict sexual risk behaviors, medication adherence, and all-cause mortality. Yet the causal pathways explaining these relationships remain poorly understood. We sought to quantify the association of trauma with negative behavioral and health outcomes and to assess whether those associations were explained by mediation through psychosocial characteristics. METHODS In 611 outpatient PLWHA, we tested whether trauma's influence on later health and behaviors was mediated by coping styles, self efficacy, social support, trust in the medical system, recent stressful life events, mental health, and substance abuse. RESULTS In models adjusting only for sociodemographic and transmission category confounders (estimating total effects), past trauma exposure was associated with 7 behavioral and health outcomes including increased odds or hazard of recent unprotected sex (OR=1.17 per each additional type of trauma, 95% CI=1.07–1.29), medication nonadherence (OR=1.13, 1.02–1.25), hospitalizations (HR=1.12, 1.04–1.22), and HIV disease progression (HR=1.10, 0.98–1.23). When all hypothesized mediators were included, the associations of trauma with health care utilization outcomes were reduced by about 50%, suggesting partial mediation (e.g., OR for hospitalization changed from 1.12 to 1.07) whereas point estimates for behavioral and incident health outcomes remained largely unchanged, suggesting no mediation (e.g., OR for unprotected sex changed from 1.17 to 1.18). Trauma remained associated with most outcomes even after adjusting for all hypothesized psychosocial mediators. CONCLUSIONS These data suggest that past trauma influences adult health and behaviors through pathways other than the psychosocial mediators considered in this model. PMID:22107822

Background: Trauma occurs in 8% of all pregnancies. To date, no studies have evaluated the effect of the hospital's trauma designation level as it relates to birth outcomes for injured pregnant women. Methods: This population-based, retrospective cohort study evaluated the association between trauma designation levels and injured pregnancy birth outcomes. We linked Washington State Birth and Fetal Death Certificate data and the Washington State Comprehensive Hospital Abstract Recording System. Injury was identified using the International Classification of Diseases, Ninth Revision injury diagnosis and external causation codes. The association was analyzed using logistic regression to estimate odds ratios and 95% confidence intervals (CIs). Results: We identified 2492 injured pregnant women. Most birth outcomes studied, including placental abruption, induction of labor, premature rupture of membranes, cesarean delivery, maternal death, gestational age <37 weeks, fetal distress, fetal death, neonatal respiratory distress, and neonatal death, showed no association with trauma hospital level designation. Patients at trauma Level 1–2 hospitals had a 43% increased odds of preterm labor (95% CI: 1.15–1.79) and a 66% increased odds of meconium at delivery (95% CI: 1.05–2.61) compared to those treated at Level 3–4 hospitals. Patients with an injury severity score >9, treated at trauma Level 1–2 hospitals, had an aOR of low birth weight, <2500 g, of 2.52 (95% CI: 1.12–5.64). Conclusions: The majority of birth outcomes for injured patients had no association with hospitalization at a Level 1–2 compared to a Level 3–4 trauma center. PMID:28971027

In this study, we aimed to determine the effects of trauma severity on cardiac involvement through evaluating the trauma severity score together with diagnostic tests in multiple trauma patients. A trauma score was determined using various trauma severity scales. After obtaining the approval of the ethics committee of the faculty, this prospective study was performed through evaluating 100 multiple trauma patients, aged over 15 years, who applied to our Emergency Department (ED). After determining the trauma severity score using instruments such as the Injury Severity Score (ISS), Glasgow Coma Scale (GCS), and Revised Trauma Score (RTS), the cardiac condition was evaluated using biochemical and radiological diagnostic tests. During the study period, 100 patients were evaluated (78 male, 22 female; mean age: 33.2±15.4; range 15 to 70 years). It was determined that 92 (92%) were blunt trauma cases, and 77 (77%) of them were due to traffic accidents. The majority of cases showed electrocardiogram (ECG) abnormalities (63%) and sinus tachycardia (36%). Abnormal echocardiogram (ECHO) findings, mostly accompanied by ventricular defects (n=24), were determined in 31 of the cases. Nineteen cases with high trauma severity score resulted in death, and 14 of all deaths were secondary to traffic accidents. Trauma scores were found to show a significant difference between the two groups. The ISS trauma scale was determined to be the most effective in terms of indicating heart involvement in patients with multiple traumas. Close follow-up and cardiac monitoring should be applied to patients with high trauma severity scores considering possible cardiac rhythm changes and hemodynamic disturbances due to cardiac involvement.

Although animal evidence indicates that early life trauma results in pervasive hippocampal deficits underlying spatial and cognitive impairment, visuo-spatial data from adult humans with early childhood adversity are lacking. We administered 4 tests of visuo-spatial ability from the Cambridge Neuorpsychological Test Automated Battery (CANTAB) to adults with a history of childhood trauma (measured by the Childhood Trauma Questionnaire) and a matched sample of healthy controls (trauma/control = 27/28). We observed a significant effect of trauma history on spatial/pattern learning. These effects could not be accounted for by adverse adult experiences, and were sex-specific, with prior adversity improving performance in men but worsening performance in women, relative to controls. Limitations include the small sample size and reliance of our study design on a retrospective, self report measure. Our results suggest that early adversity can lead to specific and pervasive deficits in adult cognitive function.

Immunoreactive serum opsonic alpha 2 sb glycoprotein as a noninvasive index of RES systemic defense after trauma.

Kaplan, J E; Saba, T M

Reticuloendothelial system (RES) depression has been correlated with diminished resistance to trauma, shock, and sepsis in man and animals. Previous studies have related the depression of RES hepatic Kupffer cell phagocytic function after trauma to diminished bioassayable opsonic activity. The present study determined if the loss of biological activity and RES alteration correlated with immunoreactive serum opsonic alpha 2 SB glycoprotein levels after trauma. Serum opsonic activity was measured by liver slice bioassay, and immunoreactive opsonic protein was measured by rocket electroimmunoassay. RE function was determined by colloid clearance over a 24-hour post-trauma period. Anesthetized rats (250-300 gm) subjected to sublethal or severe (greater than LD50) whole-body NCD trauma were the shock models investigated. Immunoreactive levels in 63 rats prior to injury were 518 +/- 24 microgram/ml. Neither biological nor immunoreactive levels were altered over 24 hours in anesthetized sham-traumatized controls. Temporal alteration in the initial decrease and recovery pattern of biologically active and immunoreactive opsonic protein levels significantly correlated following both sublethal and severe injury. Moreover, the patterns of immunoreactive levels of the opsonic protein correlated with the functional phagocytic activity of the RES as determined by vascular clearance of a test dose of blood-borne radiolabeled particulates. This glycoprotein falls after trauma, and the magnitude and duration of the decline increases with severity of injury. Immunoreactive opsonic alpha 2 SB glycoprotein appears to be an accurate measurement of circulating opsonic activity and RE Kupffer cell function after trauma, especially with respect to clearance. Thus, immunoreactive opsonic protein warrants clinical consideration as a noninvasive measure of reticuloendothelial systemic defense in patients after trauma and burn.

Cumulative childhood trauma and psychological maladjustment of sexually abused children in Korea: mediating effects of emotion regulation.

PubMed

Choi, Ji Young; Oh, Kyung Ja

2014-02-01

The purpose of the present study was to identify the mediating effects of emotion regulation on the association between cumulative childhood trauma and behavior problems in sexually abused children in Korea, using structural equation modeling (SEM). Data were collected on 171 children (ages 6-13 years) referred to a public counseling center for sexual abuse in Seoul, Korea. Cumulative childhood traumas were defined on the basis of number of traumas (physical abuse, witnessing domestic violence, neglect, traumatic separation from parent, and sexual abuse) and the severity and duration of traumas. Children were evaluated by their parents on emotion regulation using the Emotion Regulation Checklist and internalizing and externalizing behavior problems using the Korean-Child Behavior Checklist. SEM analyses confirmed the complete mediation model, in which emotion dysregulation fully mediates the relationship between cumulative childhood traumas and internalizing/externalizing behavior problems. These findings indicate that emotion regulation is an important mechanism that can explain the negative effects of cumulative childhood traumas and that there is a need to focus on emotion regulation in sexually abused children exposed to cumulative trauma.

Childhood trauma and recent life-events have been related to psychotic disorders. The aim of the present study was to examine whether childhood trauma and recent life-events are significantly more prevalent in patients at Ultra High Risk (UHR) of developing a psychotic disorder compared to healthy controls. A search of PsychInfo and Embase was conducted, relevant papers were reviewed, and three random-effects meta-analyses were performed. One meta-analysis assessed the prevalence rate of childhood trauma in UHR subjects and two meta-analyses were conducted to compare UHR subjects and healthy control subjects on the experience of childhood trauma and recent life-events. We found 12 studies on the prevalence of (childhood) trauma in UHR populations and 4 studies on recent life-events in UHR populations. We performed a meta-analysis on 6 studies (of which trauma prevalence rates were available) on childhood trauma in UHR populations, yielding a mean prevalence rate of 86.8% (95% CI 77%-93%). Childhood trauma was significantly more prevalent in UHR subjects compared to healthy control groups (Random effects Hedges' g=1.09; Z=4.60, p<.001). In contrast to our hypothesis, life-event rates were significantly lower in UHR subjects compared to healthy controls (Random effects Hedges' g=-0.53; Z=-2.36, p<.02). Our meta-analytic results illustrate that childhood trauma is highly prevalent among UHR subjects and that childhood trauma is related to UHR status. These results are in line with studies on childhood trauma in psychotic populations. In contrast to studies on recent life-events in psychotic populations, our results show that recent life-events are not associated with UHR status. Copyright © 2014 Elsevier B.V.

Some of the problems faced in trauma surgery are increasing non-operative management of abdominal injuries, decreasing work hours and increasing sub-specialisation. We wanted to document the experience of trauma team leaders at the largest trauma centre in Norway, hypothesising that the patient volume would be inadequate to secure optimal trauma care. Patients registered in the hospital based Trauma Registry during the 2-year period from 1 August 2000 to 31 July 2002 were included. Of a total of 1667 patients registered, 645 patients (39%) had an Injury Severity Score (ISS)>15. Abdominal injuries were diagnosed in 205 patients with a median ISS of 30. An average trauma team leader assessed a total of 119 trauma cases a year (46 patients with ISS>15) and participated in 10 trauma laparotomies. Although the total number of trauma cases seems adequate, the experience of the trauma team leaders with challenging abdominal injuries is limited. With increasing sub-specialisation and general surgery vanishing, fewer surgical specialties provide operative competence in dealing with complicated torso trauma. A system of additional education and quality assurance measures is a prerequisite of high quality, and has consequently been introduced in our institution.

Background. Previous studies showed significant interaction between the local and systemic inflammatory response after severe trauma in small animal models. The purpose of this study was to establish a new combined trauma model in pigs to investigate fracture-associated local inflammation and gain information about the early inflammatory stages after polytrauma. Material and Methods. Combined trauma consisted of tibial fracture, lung contusion, liver laceration, and controlled hemorrhage. Animals were mechanically ventilated and under ICU-monitoring for 48 h. Blood and fracture hematoma samples were collected during the time course of the study. Local and systemic levels of serum cytokines and diverse alarmins were measured by ELISA kit. Results. A statistical significant difference in the systemic serum values of IL-6 and HMGB1 was observed when compared to the sham. Moreover, there was a statistical significant difference in the serum values of the fracture hematoma of IL-6, IL-8, IL-10, and HMGB1 when compared to the systemic inflammatory response. However a decrease of local proinflammatory concentrations was observed while anti-inflammatory mediators increased. Conclusion. Our data showed a time-dependent activation of the local and systemic inflammatory response. Indeed it is the first study focusing on the local and systemic inflammatory response to multiple-trauma in a large animal model. PMID:25694748

Study Objectives: To investigate sleep's effect in the immediate aftermath of experiencing an analog trauma in the laboratory on reducing intrusive emotional memory formation. Methods: Sixty-five healthy women were exposed to an experimental laboratory trauma. They viewed a neutral and a trauma film in the laboratory and were randomly allocated to either a group that slept following film viewing or a group that remained awake. Sleep was recorded with electroencephalogram in a subgroup of participants in the sleep group. All participants recorded intrusive memories in the week following the film. Results: The sleep group experienced fewer and less distressing intrusive trauma memories compared to the wake group. These effects were particularly evident toward the end of the week. Duration spent in stage N2 as opposed to light N1 sleep, a higher number of fast parietal sleep spindles and a lower rapid eye movement sleep density predicted intrusion frequency. Conclusions: Our results have clinical implications and set the ground for early-intervention sleep studies following trauma and prevention of chronic posttrauma disorders.

Young, Amy M; Boyd, Carol; Hubbell, Amy

This descriptive study examined how Black women who smoke crack cocaine spoke about their experiences of sexual trauma, drug use, and the implications of these experiences for their lives. The authors also explored whether the women's perceptions of the effects of sexual abuse were related to objective indicators of mental health and drug use. The most commonly reported effects of sexual trauma were feeling dirty or ashamed or blaming self, having negative feelings toward the perpetrator, experiencing a general dislike of men or sex, and reporting a conscious reluctance to cope with the incident. In addition, conscious or unconscious denial of the effects of sexual trauma was associated with use of drugs to cope with intrapersonal and interpersonal feelings, inwardly directed responses to the trauma (e.g., self-blaming, feeling ashamed) were positively related to depression, and outwardly directed responses to the trauma (e.g., anger at the perpetrator) were positively related to self-esteem. These findings are discussed in terms of their implications for the self-medication model of substance use, treatment implications for women who have been sexually abused, and the role of self-perception in the relationship between sexual trauma and long-term outcomes.

Trauma is the leading cause of death in Americans up to 44 years old each year. Deep vein thrombosis (DVT) is a significant condition occurring in trauma, and prophylaxis is essential to the appropriate management of trauma patients. The incidence of DVT varies in trauma patients, depending on patients' risk factors, modality of prophylaxis, and methods of detection. However, compression devices and arteriovenous (A-V) foot pumps prophylaxis are recommended in trauma patients, but the efficacy and optimal use of it is not well documented in the literature. The aim of this study was to review the literature on the effect of compression devices in preventing DVT among adult trauma patients. We searched through PubMed, CINAHL, and Cochrane Central Register of Controlled Trials for eligible studies published from 1990 until June 2014. Reviewers identified all randomized controlled trials that satisfied the study criteria, and the quality of included studies was assessed by Cochrane risk of bias tool. Five randomized controlled trials were included with a total of 1072 patients. Sequential compression devices significantly reduced the incidence of DVT in trauma patients. Also, foot pumps were more effective in reducing incidence of DVT compared with sequential compression devices. Sequential compression devices and foot pumps reduced the incidence of DVT in trauma patients. However, the evidence is limited to a small sample size and did not take into account other confounding variables that may affect the incidence of DVT in trauma patients. Future randomized controlled trials with larger probability samples to investigate the optimal use of mechanical prophylaxis in trauma patients are needed.

Stress Modulates Illness-Course of Substance Use Disorders: A Translational Review

PubMed Central

Lijffijt, Marijn; Hu, Kesong; Swann, Alan C.

2014-01-01

Childhood trauma and post-childhood chronic/repeated stress could increase the risk of a substance use disorder by affecting five stages of addiction illness-course: (a) initial experimentation with substances; (b) shifting from experimental to regular use; (c) escalation from regular use to abuse or dependence; (d) motivation to quit; and (e) risk of (re-)lapse. We reviewed the human literature on relationships between stress and addiction illness-course. We explored per illness-course stage: (i) whether childhood trauma and post-childhood chronic/repeated stress have comparable effects and (ii) whether effects cut across classes of substances of abuse. We further discuss potential underlying mechanisms by which stressors may affect illness-course stages for which we relied on evidence from studies in animals and humans. Stress and substances of abuse both activate stress and dopaminergic motivation systems, and childhood trauma and post-childhood stressful events are more chronic and occur more frequently in people who use substances. Stressors increase risk to initiate early use potentially by affecting trait-like factors of risk-taking, decision making, and behavioral control. Stressors also accelerate transition to regular use potentially due to prior effects of stress on sensitization of dopaminergic motivation systems, cross-sensitizing with substances of abuse, especially in people with high trait impulsivity who are more prone to sensitization. Finally, stressors increase risk for abuse and dependence, attenuate motivation to quit, and increase relapse risk potentially by intensified sensitization of motivational systems, by a shift from positive to negative reinforcement due to sensitization of the amygdala by corticotropin releasing factor, and by increased sensitization of noradrenergic systems. Stress generally affects addiction illness-course across stressor types and across classes of substances of abuse. PMID:25101007

Negative pressure wound therapy management of the “open abdomen” following trauma: a prospective study and systematic review

PubMed Central

2013-01-01

Introduction The use of Negative Pressure Wound Therapy (NPWT) for temporary abdominal closure of open abdomen (OA) wounds is widely accepted. Published outcomes vary according to the specific nature and the aetiology that resulted in an OA. The aim of this study was to evaluate the effectiveness of a new NPWT system specifically used OA resulting from abdominal trauma. Methods A prospective study on trauma patients requiring temporary abdominal closure (TAC) with grade 1or 2 OA was carried out. All patients were treated with NPWT (RENASYS AB Smith & Nephew) to achieve TAC. The primary outcome measure was time taken to achieve fascial closure and secondary outcomes were complications and mortality. Results A total of 20 patients were included. Thirteen patients (65%) achieved fascial closure following a median treatment period of 3 days. Four patients (20%) died of causes unrelated to NPWT. Complications included fistula formation in one patient (5%) with spontaneous resolution during NPWT), bowel necrosis in a single patient (5%) and three cases of infection (15%). No fistulae were present at the end of NPWT. Conclusion This new NPWT kit is safe and effective and results in a high rate of fascial closure and low complication rates in the severely injured trauma patient. PMID:23305306

Understanding the Risk Factors of Trauma Center Closures

Objectives We analyze whether hazard rates of shutting down trauma centers are higher due to financial pressures or in areas with vulnerable populations (such as minorities or the poor). Materials and Methods This is a retrospective study of all hospitals with trauma center services in urban areas in the continental US between 1990 and 2005, identified from the American Hospital Association Annual Surveys. These data were linked with Medicare cost reports, and supplemented with other sources, including the Area Resource File. We analyze the hazard rates of trauma center closures among several dimensions of risk factors using discrete-time proportional hazard models. Results The number of trauma center closures increased from 1990 to 2005, with a total of 339 during this period. The hazard rate of closing trauma centers in hospitals with a negative profit margin is 1.38 times higher than those hospitals without the negative profit margin (P < 0.01). Hospitals receiving more generous Medicare reimbursements face a lower hazard of shutting down trauma centers (ratio: 0.58, P < 0.01) than those receiving below average reimbursement. Hospitals in areas with higher health maintenance organizations penetration face a higher hazard of trauma center closure (ratio: 2.06, P < 0.01). Finally, hospitals in areas with higher shares of minorities face a higher risk of trauma center closure (ratio: 1.69, P < 0.01). Medicaid load and uninsured populations, however, are not risk factors for higher rates of closure after we control for other financial and community characteristics. Conclusions Our findings give an indication on how the current proposals to cut public spending could exacerbate the trauma closure particularly among areas with high shares of minorities. In addition, given the negative effect of health maintenance organizations on trauma center survival, the growth of Medicaid managed care population should be monitored. Finally, high shares of Medicaid or uninsurance by themselves are not independent risk factors for higher closure as long as financial pressures are mitigated. Targeted policy interventions and further research on the causes, are needed to address these systems-level disparities. PMID:19704354

This study examined whether trauma exposure before, during, and/or after military service contributed to current levels of post-traumatic stress disorder (PTSD) and adjustment. Further, we investigated whether trauma exposure before military service was mediated or moderated by military trauma in its effects on current PTSD and adjustment. In this retrospective study, archival data from the medical records of 422 male veterans diagnosed with PTSD between December 2001 and July 2004 at a Veterans Administration Medical Center PTSD clinic were analyzed. Measures included the Clinician-Administered PTSD Scale interview as well as self-report measures assessing trauma history, health problems, and general psychopathology (including PTSD). Findings indicated that nonmilitary-related trauma was prevalent in this sample (90%). Regression analyses for PTSD symptom severity revealed that age, greater combat exposure, and a history of physical assault after military service were significantly associated with more severe PTSD symptoms. Childhood physical abuse, adult sexual trauma, and a history of being physically assaulted during military service were also significantly associated with PTSD symptom severity. Mediational analyses indicated that childhood trauma was associated with both adult trauma and increased symptomatology on various outcome measures. Moderational analyses indicated that adult trauma exposure moderated the effect of childhood trauma exposure on health complaints. Results suggest that several variables, including age, greater combat exposure, and premilitary and postmilitary traumas, are associated with increased PTSD symptomatology. This finding underscores the importance of conducting a thorough assessment of trauma when diagnosing PTSD.

Many commonly available trauma scores predict mortality, but to evaluate the success of a certain therapy or for difficult scientific and epidemiological purposes this may be insufficient in the face of improved survival rates. For outcome analysis of multiple trauma patients, the extent of medical resources needed could be an additional outcome measurement. McPeek et al. developed a potential scoring system for elective surgery patients, which was recently modified for multiple trauma patients. The current study investigated if the McPeek score could be prospectively used in multiple trauma patients and whether it could become an additional helpful tool in outcome assessment. Applicability was assessed by practical examples. In this prospective single-centre study at the University Hospital of Innsbruck, Austria, between December 2008 and November 2010 multiple trauma patients (≥ 18 years) with an injury severity score (ISS) ≥ 17 were enrolled. Besides demographic data, prehospital vital parameters and diagnoses, all diagnoses from the trauma, mortality, length of stay in the intensive care unit and the hospital were recorded. The commonly used trauma scores ISS, revised trauma score (RTS), a severity characterization of trauma (ASCOT) and trauma and injury severity score (TRISS) were applied and an observed McPeek score was allocated following end of hospitalization. The McPeek scoring system was used according to the latest modifications. A correlation between trauma scores and the McPeek score was performed. The McPeek score was then predicted by a common trauma score using ordinal regression with the polytomous universal model (PLUM method). By subtracting the predicted from the observed McPeek scores the residual McPeek value was calculated and used for practical examples of outcome analysis with the McPeek scoring system. Out of 406 identified multiple trauma patients during the study phase, 183 had to be excluded due to missing data (mainly prehospital or following transfer). A total of 223 patients (mean ISS 31.2, mean age 47.2 years) were enrolled and assigned to the population-based observed McPeek score (median 4.0). Correlation coefficients were Glasgow coma scale (GCS) 0.59, ISS 0.62, RTS 0.65, TRISS 0.74 and ASCOT 0.77 (p < 0.0001). The TRISS predicted the McPeek score best in ordinal regression (pseudo-R(2) = 0.944, p < 0.0001). The residual McPeek score (observed minus predicted) was used to illustrate the influence of the blood glucose level on admission and the influence of head injury on outcome of multiple injury patients in detail. The modified McPeek score is applicable to multiple trauma patients to assess outcome for scientific or epidemiological purposes. Its main advantage is that it quantifies outcome independently of regional or national circumstances.

The Reno Orthopaedic Center (ROC) Trauma Fellowship business curriculum is designed to provide the fellow with a graduate level business practicum and research experience. The time commitments in a typical 12-month trauma fellowship are significant, rendering a traditional didactic master's in business administration difficult to complete during this short time. An organized, structured, practical business education can provide the trauma leaders of tomorrow with the knowledge and experience required to effectively navigate the convoluted and constantly changing healthcare system. The underlying principle throughout the curriculum is to provide the fellow with the practical knowledge to participate in cost-efficient improvements in healthcare delivery. Through the ROC Trauma Fellowship business curriculum, the fellow will learn that delivering healthcare in a manner that provides better outcomes for equal or lower costs is not only possible but a professional and ethical responsibility. However, instilling these values without providing actionable knowledge and programs would be insufficient and ineffective. For this reason, the core of the curriculum is based on individual teaching sessions with a wide array of hospital and private practice administrators. In addition, each section is equipped with a suggested reading list to maximize the learning experience. Upon completion of the curriculum, the fellow should be able to: (1) Participate in strategic planning at both the hospital and practice level based on analysis of financial and clinical data, (2) Understand the function of healthcare systems at both a macro and micro level, (3) Possess the knowledge and skills to be strong leaders and effective communicators in the business lexicon of healthcare, (4) Be a partner and innovator in the improvement of the delivery of orthopaedic services, (5) Combine scientific and strategic viewpoints to provide an evidence-based strategy for improving quality of care in a cost-efficient manner, (6) Understand the political, economic, and strategic basics of private practice orthopaedics.

Effects of intranasal oxytocin on amygdala reactivity to emotional faces in recently trauma-exposed individuals.

There is a need for effective, early post-trauma preventive interventions for post-traumatic stress disorder (PTSD). Attenuating amygdala hyperreactivity early post-trauma, a likely PTSD vulnerability factor, may decrease PTSD risk. Since oxytocin modulates amygdala reactivity to emotional stimuli, oxytocin administration early post-trauma may be a promising candidate for PTSD prevention. In a randomized double-blind placebo-controlled fMRI study, we investigated effects of a single intranasal oxytocin administration (40 IU) on amygdala reactivity to happy, neutral and fearful faces in 41 recently trauma-exposed men and women showing moderate to high distress after initial post-trauma screening. We explored treatment interactions with sex. Participants were scanned within 11 days post-trauma. Compared with placebo, oxytocin significantly increased right amygdala reactivity to fearful faces. There was a significant treatment by sex interaction on amygdala reactivity to neutral faces, with women showing increased left amygdala reactivity after oxytocin. These findings indicate that a single oxytocin administration may enhance fearful faces processing in recently trauma-exposed individuals and neutral faces processing in recently trauma-exposed women. These observations may be explained by oxytocin-induced increased salience processing. Clinical implications of these findings for PTSD prevention should be further investigated.

Recent literature has indicated that exposure to multiple traumatic events in adults is associated with high levels of posttraumatic stress disorder (PTSD), anxiety, and depression. Against the backdrop of stressful life events and childhood abuse and neglect, we investigated the cumulative effect of multiple trauma exposure on PTSD, anxiety, and depression in an adolescent sample. One thousand one hundred forty 10th-grade learners from 9 Cape Town (South Africa) schools completed questionnaires on stressful life experiences; trauma exposure; and symptoms of anxiety, depression, and PTSD. Our population of interest for this study was adolescents between the ages of 14 and 18 years who had been exposed to serious, Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, qualifying traumatic events. The final sample size was thus 922. Rates of trauma exposure, PTSD, depression, and anxiety were high. Controlling for sex, stressful life experiences in the past year, and childhood adversity, we found an effect of cumulative trauma exposure effect on PTSD and depression, with an increase in the number of traumas linearly associated with an increase in symptoms of PTSD (F((4,912)) = 7.60, P < .001) and depression (F((4,912)) = 2.77, P < .05). We did not find a cumulative effect on anxiety. Our findings indicate that adolescents exposed to multiple traumas are more likely to experience more severe symptoms of PTSD and depression than those who experience a single event, with this effect independent of childhood adversity and everyday stressful life experiences. Exposure to multiple trauma, however, does not seem to be associated with more severe anxiety symptoms.

Recent paradigm shift in major trauma profile elevates chest wall injuries among the most important topics of the specialty. Due to mass casualties of terror attacks and asymmetric warfare, civilian and military trauma care challenges thoracic surgery, traumatology, intensive anesthesiology, and related specialties. Contemporary advances of the main issues are systemically presented and discussed, such as soft tissue and bony structure injuries, complex traumas like flail chest, and extensively destroyed chest wall.

Animals, including humans, require a highly coordinated and flexible system of social behavior and threat evaluation. However, trauma can disrupt this system, with the amygdala implicated as a mediator of these impairments in behavior. Recent evidence has further highlighted the context of infant trauma as a critical variable in determining its immediate and enduring consequences, with trauma experienced from an attachment figure, such as occurs in cases of caregiver-child maltreatment, as particularly detrimental. This review focuses on the unique role of caregiver presence during early-life trauma in programming deficits in social behavior and threat processing. Using data primarily from rodent models, we describe the interaction between trauma and attachment during a sensitive period in early life, which highlights the role of the caregiver’s presence in engagement of attachment brain circuitry and suppressing threat processing by the amygdala. These data suggest that trauma experienced directly from an abusive caregiver and trauma experienced in the presence of caregiver cues produce similar neurobehavioral deficits, which are unique from those resulting from trauma alone. We go on to integrate this information into social experience throughout the lifespan, including consequences for complex scenarios, such as dominance hierarchy formation and maintenance.

Background Training-induced muscle, skeletal and joint trauma may result in acute phase response reflected by the changes in the blood concentration of serum amyloid A (SAA) in racehorses. It remains yet unclear if such systemic reaction could be triggered by sport injuries and what is the impact of different types of musculoskeletal trauma on SAA concentrations in racehorses. This study aimed to determine changes in the SAA blood concentration in racehorses with different types of injuries of musculoskeletal system. Materials and Methods The study involved 28 racehorses diagnosed after the race with bone fractures (n = 7), dorsal metacarpal disease (n = 11), joint trauma (n = 4) or tendon and muscle trauma (n = 6) and 28 healthy control racehorses. Serum samples were collected twice, between 1 and 4 days of the injury or succesful completion of the race. SAA concentration was measured using the commercial ELISA kit. Differences between mean SAA concentration in respective groups were analyzed using ANOVA and Tukey post-hoc test. Results Mean SAA concentration within the first 4 days of the injury of muscle and tendon was significantly higher than in bone fractures, dorsal metacarpal disease, joint trauma or in the healthy horses (p<0,001). There were no significant differences between the other groups. Conclusions Strain injuries of muscle and tendons can cause a moderate increase in SAA blood concentration in racehorses, reflecting the occurrence of the acute phase response. Similar reaction is not observed in the stress-related bone injuries. PMID:26466121

The optimal geographic configuration of health care systems is key to maximizing accessibility while promoting the efficient use of resources. This article reports the use of a novel approach to inform the optimal configuration of a national trauma system. This is a prospective cohort study of all trauma patients, 15 years and older, attended to by the Scottish Ambulance Service, between July 1, 2013, and June 30, 2014. Patients underwent notional triage to one of three levels of care (major trauma center [MTC], trauma unit, or local emergency hospital). We used geographic information systems software to calculate access times, by road and air, from all incident locations to all candidate hospitals. We then modeled the performance of all mathematically possible network configurations and used multiobjective optimization to determine geospatially optimized configurations. A total of 80,391 casualties were included. A network with only high- or moderate-volume MTCs (admitting at least 650 or 400 severely injured patients per year, respectively) would be optimally configured with a single MTC. A network accepting lower-volume MTCs (at least 240 severely injured patients per year) would be optimally configured with two MTCs. Both configurations would necessitate an increase in the number of helicopter retrievals. This study has shown that a novel combination of notional triage, network analysis, and mathematical optimization can be used to inform the planning of a national clinical network. Scotland's trauma system could be optimized with one or two MTCs. Care management study, level IV.

Objectives To determine the prevalence of postpartum depression (PPD) among new mothers in Mississippi during 2009-2011 and evaluate the effects of different stressful life events in the year before delivery on the likelihood of PPD. Methods We used Mississippi Pregnancy Risk Assessment Monitoring System (PRAMS) 2009-2011 data (n = 3695) to evaluate the effects of different stressful life events on PPD. We categorized 13 stressors into 4 groups: financial, relational, trauma-related, and emotional. A composite score of the mothers' responses (≥10) to the three items: "I felt down, depressed, or sad", "I felt hopeless", and "I felt slowed down" was used to measure PPD. The items were rated on a Likert scale from (1) never to 5 (always). Descriptive statistics, Chi square tests, t tests, and logistic regression analyses were conducted using SAS 9.3 Proc Survey procedure (SAS Institute, Cary, NC, USA). Results The overall prevalence of self-reported PPD was 14.8 %. Mothers who experienced high relational with low financial and high trauma related stresses had the highest likelihood of PPD diagnosis after adjusting for confounders (OR = 8.6; 95 % CI, 3.5-21.3), followed by those who reported high relational stress with low financial and low trauma stresses (OR = 5.9; 95 % CI, 3.5-10.2). Those with high financial, low relational, and low trauma had the least likelihood of PPD (OR = 2.2; 95 % CI, 1.6-3.0) compared to women with low stress in all three categories. Conclusion Our findings showed that the likelihood of PPD was higher among women who had high relational stress, indicating that efforts to effectively prevent PPD need to focus on healthy relationships between partners during pregnancy.

To compare accuracy and to check the suitability of the Glasgow Coma Scale (GCS), the Revised Trauma Score (RTS), the Injury Severity Score (ISS), the New Injury Severity Score (NISS) and the Trauma and Injury Severity Score (TRISS), the scoring systems widely used in international trauma studies, in the evaluation of the "life threatening injury" concept established by the Turkish Penal Code. The age, sex, type of trauma, type and localizations of wounds, GCS, RTS, ISS, NISS and TRISS values, the decision of life threatening injury of 627 trauma patients admitted to Emergency Department of the Uludag University Medical School Hospital in year 2003 were examined. A life-threatening injury was present in 35.2% of the cases examined. GCS, RTS, ISS, NISS and TRISS confirmed the decision of life threatening injury with percentages of 74.8%, 76.9%, 88.7%, 86.6% and 68.6%, respectively. The best cut-off point 14 was determined in the ISS system with 79.6% sensitivity and 93.6% specificity. All of the cases with sole linear skull fracture officially decided as life threatening injury had an ISS of 5, a NISS of 6 and the best scores of GCS (15), RTS (7.8408) and TRISS (100%). ISS and NISS appeared to be the best trauma scoring systems that can be used for the decision of life threatening injury, compared with GCS, RTS and TRISS. Thus, ISS and NISS can be acceptable for using the evaluation of the life threatening injury concept established by the Turkish Penal Code.

Dropout among patients in qualified alcohol detoxification treatment: the effect of treatment motivation is moderated by Trauma Load.

PubMed

Odenwald, Michael; Semrau, Peter

2013-03-21

Motivation to change has been proposed as a prerequisite for behavioral change, although empirical results are contradictory. Traumatic experiences are frequently found amongst patients in alcohol treatment, but this has not been systematically studied in terms of effects on treatment outcomes. This study aimed to clarify whether individual Trauma Load explains some of the inconsistencies between motivation to change and behavioral change. Over the course of two months in 2009, 55 patients admitted to an alcohol detoxification unit of a psychiatric hospital were enrolled in this study. At treatment entry, we assessed lifetime Trauma Load and motivation to change. Mode of discharge was taken from patient files following therapy. We tested whether Trauma Load moderates the effect of motivation to change on dropout from alcohol detoxification using multivariate methods. 55.4% dropped out of detoxification treatment, while 44.6% completed the treatment. Age, gender and days in treatment did not differ between completers and dropouts. Patients who dropped out reported more traumatic event types on average than completers. Treatment completers had higher scores in the URICA subscale Maintenance. Multivariate methods confirmed the moderator effect of Trauma Load: among participants with high Trauma Load, treatment completion was related to higher Maintenance scores at treatment entry; this was not true among patients with low Trauma Load. We found evidence that the effect of motivation to change on detoxification treatment completion is moderated by Trauma Load: among patients with low Trauma Load, motivation to change is not relevant for treatment completion; among highly burdened patients, however, who a priori have a greater risk of dropping out, a high motivation to change might make the difference. This finding justifies targeted and specific interventions for highly burdened alcohol patients to increase their motivation to change.

The development of trauma systems and trauma centers has had a major impact on the fate of the critically injured patient. However, some have suggested that care may be compromised if too many trauma centers are designated for a given area. As of 1987, the state of Missouri had designated six adult trauma centers, two Level I and four Level II, for the metropolitan Kansas City, Mo, area, serving a population of approximately 1 million people. To determine whether care was comparable between the Level I and II centers, we conducted a concurrent evaluation of the fate of patients with a sentinel injury, hepatic trauma, over a 6-year period (1987-1992) who were treated at these six trauma centers. All patients during the 6-year study period who suffered liver trauma and who survived long enough to be evaluated by computerized tomography or celiotomy were entered into the study. Patients with central nervous system trauma were excluded from analysis. Information concerning mechanism of injury, RTS, Injury Severity Score (ISS), presence of shock, liver injury scoring, mode of treatment, mortality, and length of stay were recorded on abstract forms for analysis. Care was evaluated by mortality, time to the operating room (OR), and intensive care unit (ICU) and hospital length of stay. Over the 6-year period 300 patients with non-central nervous system liver trauma were seen. Level I centers cared for 195 patients and Level II centers cared for 105. There was no difference in mean ISS or ISS > 25 between Level I and II centers. Fifty-five (28%) patients arrived in shock at Level I centers and 24 (23%) at Level II centers. Forty-eight patients (16%) died. Thirty-two (16%) died at Level I centers, and 16 (15%) died at Level II centers. Twenty of 55 patients (36%) in shock died at Level I centers, and 11 of 24 (46%) died at Level II centers (p = 0.428). Forty-three patients (22%) had liver scaling scores of IV-VI at Level I centers, and 10 (10%) had similar scores at Level II centers (p < 0.01). With liver scores IV-VI, 22 of 43 (51%) died at Level I centers and 10 of 14 (71%) died at Level II centers (p = 0.184). There was no difference in mean time or in delays beyond 1 hour to the OR for those patients in shock between Level I and II centers. There was a longer ICU stay at Level II centers (5.0 +/- 8.3 vs. 2.8 +/- 8.4 days, p = 0.04). This difference was confined to penetrating injuries. There was no difference in hospital length of stay. In a metropolitan trauma system, when Level I and II centers were compared for their ability to care for victims of hepatic trauma, there was no discernible difference in care rendered with respect to severity of injury, mortality, delays to the OR, or hospital length of stay. It was observed that more severe liver injuries were seen at Level I centers, but this did not seem to significantly affect care at Level II centers. There was a longer ICU stay observed at Level II centers owing to penetrating injuries, possibly because there were fewer penetrating injuries treated at these facilities. Although the bulk of patients were seen at Level I centers, care throughout the system was equivalent.

Sex differences in the epidemiology and clinical presentation of trauma-related psychopathology have long been documented. Multiple underlying mechanisms have been examined, both psychosocial and biological. Among the most promising biological mechanisms are neural substrates of trauma-related psychopathology that have been uncovered in recent years. Neuroimaging studies of sex-related heterogeneity published over the past 3 years (2014-2017) demonstrate an interaction between sex and type, timing, and load of trauma exposure. These studies suggest that, for males, early trauma exposure may involve a loss of gray matter in the limbic system, including the prefrontal cortex (PFC), amygdala, and hippocampus, and an over-activity and increased connectivity of salience hubs, and particularly dorsal anterior cingulate cortex (dACC). For females, however, early trauma exposure may involve overactive and possibly an enlarged amygdala, as well as decreased connectivity of salience hubs such as the dACC. Underlying mechanisms may include interaction with several endocrine systems and result in differential neural response to naturally occurring and added endocrine ligands, as well as sex-specific genetic and epigenetic risk and resilience factors. This complex interaction between multiple biological systems may be associated with sex-specific behavioral patterns, in turn associated with trauma-related psychopathology. While substantial number of published studies present preliminary evidence for neural mechanisms of sex-specific posttraumatic responses, there is a paucity of research directly designed to examine sex as a biological factor in trauma-related psychopathology. Specific foci for future studies aiming to bridge current gaps in the literature are discussed.

Dose reduction in whole-body computed tomography of multiple injuries (DoReMI): protocol for a prospective cohort study

PubMed Central

2014-01-01

Background Single-pass, contrast-enhanced whole body multidetector computed tomography (MDCT) emerged as the diagnostic standard for evaluating patients with major trauma. Modern iterative image algorithms showed high image quality at a much lower radiation dose in the non-trauma setting. This study aims at investigating whether the radiation dose can safely be reduced in trauma patients without compromising the diagnostic accuracy and image quality. Methods/Design Prospective observational study with two consecutive cohorts of patients. Setting: A high-volume, academic, supra-regional trauma centre in Germany. Study population: Consecutive male and female patients who 1. had been exposed to a high-velocity trauma mechanism, 2. present with clinical evidence or high suspicion of multiple trauma (predicted Injury Severity Score [ISS] ≥16) and 3. are scheduled for primary MDCT based on the decision of the trauma leader on call. Imaging protocols: In a before/after design, a consecutive series of 500 patients will undergo single-pass, whole-body 128-row multi-detector computed tomography (MDCT) with a standard, as low as possible radiation dose. This will be followed by a consecutive series of 500 patients undergoing an approved ultra-low dose MDCT protocol using an image processing algorithm. Data: Routine administrative data and electronic patient records, as well as digital images stored in a picture archiving and communications system will serve as the primary data source. The protocol was approved by the institutional review board. Main outcomes: (1) incidence of delayed diagnoses, (2) diagnostic accuracy, as correlated to the reference standard of a synopsis of all subsequent clinical, imaging, surgical and autopsy findings, (3) patients’ safety, (4) radiation exposure (e.g. effective dose), (5) subjective image quality (assessed independently radiologists and trauma surgeons on a 100-mm visual analogue scale), (6) objective image quality (e.g., contrast-to-noise ratio). Analysis: Multivariate regression will be employed to adjust and correct the findings for time and cohort effects. An exploratory interim analysis halfway after introduction of low-dose MDCT will be conducted to assess whether this protocol is clearly inferior or superior to the current standard. Discussion Although non-experimental, this study will generate first large-scale data on the utility of imaging-enhancing algorithms in whole-body MDCT for major blunt trauma.

Over a million children are subjected to some form of trauma in the United States every year. Early trauma has been shown to have deleterious effects on cardiovascular health in adulthood. However, the presence of strong social relationships as an adult can buffer an individual against many of the harmful effects of early trauma. Furthermore, the perception of social isolation has been shown to be a significant risk factor for the development of cardiovascular disease and is a strong predictor of all cause mortality. One likely mechanism thought to underlie the influence of perceived isolation on health is changes in arterial stiffness. One of the more widely used measures of arterial stiffness in older individuals is pulse pressure. The goal of the present study was to determine whether early childhood trauma is associated with elevations on pulse pressure. Furthermore, this study sought to determine whether perceived social isolation moderates the relationship between early trauma and pulse pressure. Results revealed that individuals with low perceived social isolation displayed no significant relationship between early trauma and pulse pressure. However, individuals who reported higher levels of perceived isolation showed a significant positive association between early trauma and pulse pressure. Therefore, the detrimental effects of early trauma may be partially dependent upon the quality of social relationships as an adult. Copyright © 2012 Elsevier B.V. All rights reserved.

Trauma team training provides instruction on crisis management through debriefing and discussion of teamwork and leadership skills during simulated trauma scenarios. The effects of team leader's nontechnical skills (NTSs) on technical performance have not been thoroughly studied. We hypothesized that team's and team leader's NTSs correlate with technical performance of clinical tasks. Retrospective cohort study. Brigham and Women's Hospital, STRATUS Center for Surgical Simulation A total of 20 teams composed of surgical residents, emergency medicine residents, emergency department nurses, and emergency services assistants underwent 2 separate, high-fidelity, simulated trauma scenarios. Each trauma scenario was recorded on video for analysis and divided into 4 consecutive sections. For each section, 2 raters used the Non-Technical Skills for Surgeons framework to assess NTSs of the team. To evaluate the entire team's NTS, 2 additional raters used the Modified Non-Technical Skills Scale for Trauma system. Clinical performance measures including adherence to guidelines and time to perform critical tasks were measured independently. NTSs performance by both teams and team leaders in all NTS categories decreased from the beginning to the end of the scenario (all p < 0.05). There was significant correlation between team's and team leader's cognitive skills and critical task performance, with correlation coefficients between 0.351 and 0.478 (p < 0.05). The NTS performance of the team leader highly correlated with that of the entire team, with correlation coefficients between 0.602 and 0.785 (p < 0.001). The NTSs of trauma teams and team leaders deteriorate as clinical scenarios progress, and the performance of team leaders and teams is highly correlated. Cognitive NTS scores correlate with critical task performance. Increased attention to NTSs during trauma team training may lead to sustained performance throughout trauma scenarios. Decision making and situation awareness skills are critical for both team leaders and teams and should be specifically addressed to improve performance.

This study aimed to determine the relative "weight" of risk factors known to be associated with venous thromboembolism (VTE) for patients with trauma based on injuries and comorbidities. A retrospective review of 16,608 consecutive admissions to a trauma center was performed. Patients were separated into those who developed VTE (n = 141) versus those who did not (16,467). Univariate analysis was performed for each risk factor reported in the trauma literature. Risk factors that were shown to be significant (p < 0.05) by univariate analysis underwent multivariate analysis to develop odds ratios for VTE. The Trauma Embolic Scoring System (TESS) was derived from the multivariate coefficients. The resulting TESS was compared with a data set from the National Trauma Data Bank (2002-2006) to determine its ability to predict VTE. The multivariate analysis demonstrated that age, Injury Severity Score, obesity, ventilator use for more than 3 days, and lower-extremity trauma were significant predictors of VTE in our patient population. The TESS was from 0 to 14, with the best prediction for those patients with a score of more than 6 (sensitivity, 81.6%; specificity, 84%). Overall, the model had excellent discrimination in predicting VTE with a receiver operating characteristic curve of 0.89. The VTE rates for TESS in the National Trauma Data Bank data set were similar for all integers except for 3 and 4, in which the VTE rates were significantly higher (3, 0.2% vs. 0.6%; 4, 0.4% vs. 1.0%). The TESS provides an objective measure of classifying VTE risk for patients with trauma. The TESS could allow informed decision making regarding prophylaxis strategies in patients with trauma.

As many as half of all patients with major traumatic injuries do not receive the recommended care, with variance in preventable mortality reported across the globe. This variance highlights the need for a comprehensive process for monitoring and reviewing patient care, central to which is a consistent peer-review process that includes trauma system safety and human factors. There is no published, evidence-informed standardised tool that considers these factors for use in adult or paediatric trauma case peer-review. The aim of this research was to develop and validate a trauma case review tool to facilitate clinical review of paediatric trauma patient care in extracting information to facilitate monitoring, inform change and enable loop closure. Development of the trauma case review tool was multi-faceted, beginning with a review of the trauma audit tool literature. Data were extracted from the literature to inform iterative tool development using a consensus approach. Inter-rater agreement was assessed for both the pilot and finalised versions of the tool. The final trauma case review tool contained ten sections, including patient factors (such as pre-existing conditions), presenting problem, a timeline of events, factors contributing to the care delivery problem (including equipment, work environment, staff action, organizational factors), positive aspects of care and the outcome of panel discussion. After refinement, the inter-rater reliability of the human factors and outcome components of the tool improved with an average 86% agreement between raters. This research developed an evidence-informed tool for use in paediatric trauma case review that considers both system safety and human factors to facilitate clinical review of trauma patient care. This tool can be used to identify opportunities for improvement in trauma care and guide quality assurance activities. Validation is required in the adult population.

In the US military, it is common for health care teams to be formed ad hoc and expected to function cohesively as a unit. Poor team dynamics decreases the effectiveness of trauma care delivery. The US Navy Fleet Surgical Team Three has developed a simulation-based trauma initiative-the Shipboard Surgical Trauma Training (S2T2) Course-that emphasizes team dynamics to improve the delivery of trauma care to the severely injured patient. The S2T2 Course combines classroom didactics with hands-on simulation over a period of 6 days, culminating in a daylong, mass casualty scenario. Each resuscitation team was initially evaluated with a simulated trauma resuscitation scenario then retested on the same scenario after completing the course. A written exam was also administered individually both before and after the course. A survey was administered to assess the participants' perceived effectiveness of the course on overall team training. From the evaluation of 20 resuscitation teams made up of 123 medical personnel, there was a decrease in the mean time needed to perform the simulated trauma resuscitation, from a mean of 24.4 minutes to 13.5 minutes (P < .01), a decrease in the mean number of critical events missed, from 5.15 to 1.00 (P < .01), and a mean improvement of 41% in written test scores. More than 90% of participants rated the course as highly effective for improving team dynamics. A team-based trauma course with immersion in a realistic environment is an effective tool for improving team performance in trauma training. This approach has high potential to improve trauma care and patient outcomes. The benefits of this team-based course can be adapted to the civilian rural sector, where gaps have been identified in trauma care. Published by Elsevier Inc.

Injury rates in low- and middle-income countries are among the greatest in the world, with >90% of unintentional injury occurring in low- or middle-income countries. The risk of death from injuries is 6 times more in low- and middle-income countries than in high-income countries. This increased rate of injury is partly due to the lack of availability and access to timely and appropriate medical care for injured individuals. Kenya, like most low- and middle-income countries, has seen a 5-fold increase in injury fatalities throughout the past 4 decades, in large part related to the absence of a coordinated, integrated system of trauma care. We aimed to assess the trauma-care system in Kenya and to develop and implement a plan to improve it. A trauma system profile was performed to understand the landscape for the care of the injured patient in Kenya. This process helped identify key gaps in care ranging from prehospital to hospital-based care. In response to this observation, a 9-point plan to improve trauma care in Kenya was developed and implemented in close collaboration with local stakeholders. The 9-point plan was centered on engagement of the stakeholders, generation of key data to guide and improve services, capacity development for prehospital and hospital care, and strengthening policy and legislation. There is an urgent need for coordinated strategies to provide appropriate and timely medical care to injured individuals in low- or middle-income countries to decrease the burden of injuries and related fatalities. Our work in Kenya shows that such an integrated system of trauma care could be achieved through a step-by-step integrated and multifaceted approach that emphasizes engagement of local stakeholders and evidence-based approaches to ensure effectiveness, efficiency, and sustainability of system-wide improvements. This plan and lessons learned in its development and implementation could be adaptable to other similar settings to improve the care of the injured patient in low- or middle-income countries.

Some aspects of the pathophysiology of complications in multiple-trauma patients still remain unclear. Mediators of inflammation have been postulated as playing a key role in being responsible for life threatening complications of multiple trauma patients. The objective of this study was to evaluate the prognostic value of procalcitonin (PCT) level in multiple trauma patients. A prospective study took place including patients with multiple trauma hospitalised in several hospital units. PCT level was measured in blood from 45 patients, aged 18-70 years using enzyme-linked immunoassay. The patients were divided into three groups: group I - individuals with multiple trauma with central nervous system injury; group II - those with multiple trauma without CNS injury; and group III - patients with isolated central nervous system injury. Initial PCT levels were below 0.5 ng mL(-1) regardless of the cause of trauma. In the 24th hour of observation, a statistically significant increase of PCT concentration vs. initial levels was recorded in all groups of patients. Then PCT levels decreased significantly at the 3rd measurement point in all groups, and they remained unchanged until the last measurement. The highest levels of PCT were observed in multiple trauma patients without CNS injury (group II). In this group of patients, a significantly longer duration of surgery in the post-trauma period affected PCT levels. PCT concentrations in patients who died were significantly greater than in survivors. A long lasting elevated concentration of procalcitonin in the post-traumatic period, or its repeated increase, is a good marker of developing complications observed earlier than clinical manifestations.

The aim of the study was to compare the long-term effects of conflict-related sexual violence experienced at the end of World War II (WWII) with non-sexual WWII trauma (e.g., being exposed to shell shock or physical violence). A total of 27 elderly wartime rape survivors were compared to age- and gender-matched control subjects who were drawn from a larger sample of subjects over 70 years of age who had experienced WWII-related trauma. A modified version of the Posttraumatic Diagnostic Scale was used to assess trauma characteristics and posttraumatic stress disorder (PTSD) symptoms and the Brief Symptom Inventory-18 was used to assess current psychopathology. Additionally, measures of posttraumatic growth (Posttraumatic Growth Inventory) and social acknowledgement as a trauma survivor (Social Acknowledgement Questionnaire) were used to assess two mediating variables in post-trauma conditions of rape victims. Women exposed to conflict-related sexual violence reported greater severity of PTSD-related avoidance and hyperarousal symptoms, as well as anxiety, compared with female long-term survivors of non-sexual WWII trauma. The vast majority (80.9 %) of these women also reported severe sexual problems during their lifetimes relative to 19.0 % of women who experienced non-sexual war trauma. Women exposed to conflict-related sexual violence also reported greater posttraumatic growth, but less social acknowledgement as trauma survivors, compared to survivors of non-sexual war trauma. The results were consistent with emerging neurobiological research, which suggests that different traumas may be differentially associated with long-term posttraumatic sequelae in sexual assault survivors than in other survivor groups and highlights the need to treat (or better prevent) deleterious effects of conflict-related sexual violence in current worldwide crisis zones.

Trauma and depression are associated with brain structural alterations; their combined effects on these outcomes are unclear. We previously reported a negative effect of trauma, independent of depression, on verbal learning and memory; less is known about underlying structural associates. We investigated separate and interactive associations of trauma and depression on brain structure. Adults aged 30-89 (N = 203) evaluated for depression (D+) and trauma history (T+) using structured clinical interviews were divided into 53 D+T+, 42 D+T-, 50 D-T+, and 58 D-T-. Multivariable linear regressions examined the separate and interactive associations of depression and trauma with prefrontal and temporal lobe cortical thickness composites and hippocampal volumes adjusting for age, sex, predicted verbal IQ, comorbid anxiety, and vascular risk. Significant results informed analyses of tract-based structural connectomic measures of efficiency and centrality. Trauma, independent of depression, was associated with greater left prefrontal cortex (PFC) thickness, in particular the medial orbitofrontal cortex and pars orbitalis. A trauma × depression interaction was observed for the right PFC in age-stratified analyses: Older D + T+ had reduced PFC thickness compared with older D - T+ individuals. Regardless of age, trauma was associated with more left medial orbitofrontal cortex efficiency and less pars orbitalis centrality. In the T+ group, left pars orbitalis cortical thickness and centrality negatively correlated with verbal learning. Trauma, independent of depression, associated with altered PFC characteristics, morphologically and in terms of structural network communication and influence. Additionally, findings suggest that there may be a combined effect of trauma and depression in older adults. Copyright © 2017 John Wiley & Sons, Ltd. Copyright © 2017 John Wiley & Sons, Ltd.

What is the effect of the weather on trauma workload? A systematic review of the literature.

Hospital admission rates for a number of conditions have been linked to variations in the weather. It is well established that trauma workload displays significant seasonal variation. A reliable predictive model might enable targeting of high-risk groups for intervention and planning of hospital staff levels. To our knowledge there have been no systematic reviews of the literature on the relationship between weather and trauma workload, and predictive models have thus far been informed by the results of single studies. We conducted a systematic review of bibliographic databases and reference lists up to June 2014 to identify primary research papers assessing the effect of specified weather conditions including temperature, rainfall, snow, fog, hail, humidity and wind speed on trauma workload, defined as admission to hospital, fracture or a Road Traffic Accident (RTA) resulting in a seriously injured casualty or fatality. 11,083 papers were found through electronic and reference search. 83 full papers were assessed for eligibility. 28 met inclusion criteria and were included in the final review; 6 of these related to the effect of the weather on trauma admissions, one to ambulance call out for trauma, 13 to fracture rate and 8 to RTAs. Increased temperature is positively correlated with trauma admissions. The rate of distal radius fractures is more sensitive to adverse weather than the rate of hip fractures. Paediatric trauma, both in respect of trauma admissions and fracture rate, is more sensitive to the weather than adult trauma. Adverse weather influences both RTA frequency and severity, but the nature of the relationship is dependent upon the timecourse of the weather event and the population studied. Important methodological differences between studies limit the value of the existing literature in building consensus for a generalisable predictive model. Weather conditions may have a substantial effect on trauma workload independent of the effects of seasonal variation; the population studied and timecourse of weather events appear critical in determining this relationship. Methodological differences between studies limit the validity of conclusions drawn from analysis of the literature, and we identify a number of areas that future research might address.

Although sex- and gender-specific analyses have been gaining more attention during the last years they have rarely been performed in orthopaedic literature. The primary purpose of this study was to investigate whether for injuries of the UCL the specific location of the rupture is influenced by sex. A secondary study question addressed the sex-independent effect of trauma intensity on the rupture site of the UCL. This study is a retrospective analysis of all patients with either a proximal or distal bony avulsion or with a mid-substance tear or ligament avulsion of the UCL treated surgically between 1992 and 2015 at two level-I trauma centres. Trauma mechanisms leading to the UCL injury were classified into the following categories: (1) blunt trauma (i.e., strains), (2) low-velocity injuries (e.g., fall from standing height, assaults), and (3) high-velocity injuries (e.g., sports injuries, motor vehicle accidents). After reviewing the surgical records, patients were divided into three groups, depending upon the ligament rupture site: (1) mid-substance tears, (2) proximal ligament or bony avulsions and (3) distal ligament or bony avulsions. Dependencies between the specific rupture site and the explanatory variables (sex, age, and trauma intensity) were evaluated using χ2 test and logistic regression analysis. In total, 1582 patients (1094 males, 488 females) met the inclusion criteria. Mean age was 41 years (range: 9-90 years). Taking into account the effects of sex on trauma intensity (p<0.001) and of trauma intensity on rupture site (p<0.001), mid-substance tears occurred more frequently in women, whereas men were more prone to distal ligament or bony avulsions (p<0.001). In other words, sex and rupture site correlated due to the effects of sex on trauma intensity and of trauma intensity on rupture site, but taking into account those effects there still was a significant effect of sex on rupture site. The results of this study demonstrate that with regression analysis both sex and trauma intensity allow to predict rupture site in UCL injuries.

Trauma care benefits from the use of imaging technologies. Trauma patients and trauma team members are exposed to radiation during the continuum of care. Knowledge of exposure amounts and effects are important for trauma team members. We performed a review of the published literature; keywords included "trauma," "patients," "trauma team members," "wounds," "injuries," "radiation," "exposure," "dose" and "computed tomography" (CT). We also reviewed the Board on Radiation Effects Research (BEIR VII) report, published in 2005 and 2006. We found no randomized controlled trials or studies. Relevant studies demonstrated that CT accounts for the single largest radiation exposure in trauma patients. Exposure to 100 mSv could result in a solid organ cancer or leukemia in 1 of 100 people. Trauma team members do not exceed the acceptable occupation radiation exposure determined by the National Council of Radiation Protection and Management. Modern imaging technologies such as 16- and 64-slice CT scanners may decrease radiation exposure. Multiple injured trauma patients receive a substantial dose of radiation. Radiation exposure is cumulative. The low individual risk of cancer becomes a greater public health issue when multiplied by a large number of examinations. Though CT scans are an invaluable resource and are becoming more easily accessible, they should not replace careful clinical examination and should be used only in appropriate patients.

Self-distancing from trauma memories reduces physiological but not subjective emotional reactivity among Veterans with posttraumatic stress disorder.

Self-distancing, or viewing oneself from a third-person perspective, reduces reactivity when analyzing one's feelings. Self-distancing may have important effects among individuals with posttraumatic stress disorder (PTSD), who have heightened emotional and physiological reactivity to trauma memories, but the effects of self-distancing in this group are unclear. We randomly assigned 48 Veterans diagnosed with PTSD to analyze their trauma-related feelings from an immersed (first-person) or distanced (third-person) perspective, and measured physiological and subjective emotional reactivity. Self-distancing during trauma analysis protected against increases in physiological reactivity, such that participants in the immersed condition showed a significant increase in heart rate and skin conductance responses not seen in the distanced condition. However, self-distancing had no effect on self-reported emotional reactivity. Our findings suggest that the effects of self-distancing on subjective emotions may not extend to trauma memories. However, self-distancing during trauma analysis did change physiological reactivity, suggesting at least a short-term benefit for individuals with PTSD.

How can the auditory efferent system protect our ears from noise-induced hearing loss? Let us count the ways

It is a cause for some debate as to how the auditory olivocochlear (OC) efferent system could protect hearing from noise trauma. In this review, we examined physiological research to find mechanisms that could effectively attenuate the response to sound. For each purported mechanism, we indicate which part of the OC-efferent system is responsible for the function and the site of action. These mechanisms include basilar-membrane phase shifts at high stimulus levels; changes in outer-hair-cell stiffness and phase lag associated with efferent slow effects; small decreases in endocochlear potentials causing small decreases in outer- and inner-hair-cell output; low-spontaneous-rate and medium-spontaneous-rate fibers showing OC-induced decrements at high levels; auditory-nerve initial-peak reduction; OC effect increasing over minutes; cholinergic activation of anti-apoptotic pathways; and anti-excitotoxicity. There are clearly multiple opportunities for the OC-efferent system to protect the inner ear from noise trauma. From further exploration into the mechanisms outlined here, as well as to-be-discovered mechanisms, we will gain a greater understanding of the protective nature of the OC-efferent system. These findings could aid our ability to design better predictive tests for people at risk for noise-induced hearing loss.

A structured research programme is one of the main pillars of a trauma care system. Despite the high rate of injury-related mortalities, especially road traffic accidents, in Qatar, little consideration has been given to research in trauma. This review aimed to analyse research publications on the subject of trauma published from Qatar and to discuss the progress of clinical research in Qatar and the Gulf Cooperation Council countries with special emphasis on trauma research. A literature search using PubMed and Google Scholar search engines located 757 English-language articles within the fields of internal medicine, surgery and trauma originating from Qatar between the years 1993 and 2013. A steep increase in the number of trauma publications since 2010 could be linked to the setting up of a trauma research centre in Qatar in 2011. We believe that establishing a research unit has made a major impact on research productivity, which ultimately benefits health care.

Trauma-Informed HIV Prevention and Treatment.

The high prevalence of trauma and its negative impact on health and health-promoting behaviors underscore the need for multi-level interventions to address trauma and its associated sequelae to improve physical and mental well-being in both HIV-infected and HIV-uninfected populations. Growing global awareness of the intersection of trauma and HIV has resulted in development and testing of interventions to address trauma in the context of HIV treatment and HIV prevention in the USA and globally. Despite increasing recognition of the widespread nature of trauma and the importance of trauma to HIV transmission around the globe, several gaps remain. Through a survey of the literature, we identified eight studies (published in the past 5 years) describing interventions to address the effects of trauma on HIV-related outcomes. In particular, this study focused on the levels of intervention, populations the interventions were designed to benefit, and types of trauma addressed in the interventions in the context of both HIV prevention and treatment. Remarkably absent from the HIV prevention, interventions reviewed were interventions designed to address violence experienced by men or transgender individuals, in the USA or globally. Given the pervasive nature of trauma experienced generally, but especially among individuals at heightened risk for HIV, future HIV prevention interventions universally should consider becoming trauma-informed. Widespread acknowledgement of the pervasive impact of gender-based violence on HIV outcomes among women has led to multiple calls for trauma-informed care (TIC) approaches to improve the effectiveness of HIV services for HIV-infected women. TIC approaches may be relevant for and should also be tested among men and all groups with high co-occurring epidemics of HIV and trauma (e.g., men who have sex with men (MSM), transgendered populations, injection drug users, sex workers), regardless of type of trauma experience.

Suicidal ideation (SI) is a serious issue affecting U.S. veterans, and those with posttraumatic stress disorder (PTSD) are at an especially high risk of SI. Guilt has been associated with both PTSD and SI and may therefore be an important link between these constructs. The present study compared models of trauma-related guilt and used path analysis to examine the direct and indirect effects of PTSD and trauma-related guilt on SI among a sample of 988 veterans receiving outpatient PTSD treatment at a Veterans Affairs (VA) specialty clinic. Results showed that a model of trauma-related guilt including guilt-cognitions and global guilt (but not distress) provided the best model fit for the data. PTSD and trauma-related guilt had direct effects on SI, and PTSD exhibited indirect effects on SI via trauma-related guilt. The use of cross-sectional data limits the ability to make causal inferences. A treatment-seeking sample composed primarily of Vietnam veterans limits generalizability to other populations. Trauma-related guilt, particularly guilt cognitions, may be an effective point of intervention to help reduce SI among veterans with PTSD. This is an important area of inquiry, and suggestions for future research are discussed. Published by Elsevier B.V.

Despite important advances in the prevention and treatment of trauma, preventable injuries continue to impact the lives of millions of people. Motor vehicle collisions and violence claim close to 3 million lives each year worldwide. Public health agencies have promoted the need for systematic and ongoing surveillance as a foundation for successful injury control. Surveillance has been used to quantify the incidence of injury for the prioritization of further research, monitor trends over time, identify new injury patterns, and plan and evaluate prevention and intervention efforts. Advances in capability to handle spatial data and substantial increases in computing power have positioned geographic information science (GIS) as a potentially important tool for health surveillance and the spatial organization of health care, and for informing prevention and acute care interventions. Two themes emerge in the trauma literature with respect to GIS theory and techniques: identifying determinants associated with the risk of trauma to guide injury prevention efforts and evaluating the spatial organization and accessibility of acute trauma care systems. We review the current literature on trauma and GIS research and provide examples of the importance of accounting for spatial scale when using spatial analysis for surveillance. The examples illustrate the effect of scale on incident analysis, the geographic variation of major injury across British Columbia's health service delivery areas (HSDAs) and the rates of variation of injury within individual HSDAs.

The protective effect of 2-mercaptoethane sulfonate (MESNA) against traumatic brain injury in rats.

The agent, 2-mercaptoethane sulfonate (MESNA), is a synthetic small molecule, widely used as a systemic protective agent against chemotherapy toxicity, but is primarily used to reduce hemorrhagic cystitis induced by cyclophosphamide. Because MESNA has potential antioxidant and cytoprotective effects, so we hypothesized that MESNA may protect the brain against traumatic injury. Thirty-two rats were randomized into four groups of eight animals each; Group 1 (sham), Group 2 (trauma), Group 3 (150 mg/kg MESNA), Group 4 (30 mg/kg methylprednisolone). Only skin incision was performed in the sham group. In all the other groups, the traumatic brain injury model was created by an object weighing 450 g falling freely from a height of 70 cm through a copper tube on to the metal disc over the skull. The drugs were administered immediately after the injury. The animals were killed 24 h later. Brain tissues were extracted for analysis, where levels of tissue malondialdehyde, caspase-3, glutathione peroxidase, superoxide dismutase, nitric oxide, nitric oxide synthetase and xanthine oxidase were analyzed. Also, histopathological evaluation of the tissues was performed. After head trauma, tissue malondialdehyde levels increased; these levels were significantly decreased by MESNA administration. Caspase-3 levels were increased after trauma, but no effect of MESNA was determined in caspase-3 activity. Following trauma, both glutathione peroxidase and superoxide dismutase levels were decreased; MESNA increased the activity of both these antioxidant enzymes. Also, after trauma, nitric oxide, nitric oxide synthetase and xanthine oxidase levels were increased; administration of MESNA significantly decreased the levels of nitric oxide, nitric oxide synthetase and xanthine oxidase, promising an antioxidant activity. Histopathological analysis showed that MESNA protected the brain tissues well from injury. Although further studies considering different dose regimens and time intervals are required, MESNA was shown to be at least as effective as methylprednisolone in the traumatic brain injury model.

Self-reports of trauma and dissociation: An examination of context effects.

Lemons, Peter; Lynn, Steven Jay

2016-08-01

To examine context effects in moderating the link between self-reported trauma and dissociation in undergraduate samples, we administered these measures either in the same or different experimental contexts. Trauma History Screen/THS (Carlson et al., 2011)-Dissociative Experiences Scale/DES-II (Bernstein & Putnam, 1986) correlations revealed a context effect (greater correlations in same test context), although multiple regression analyses did not confirm this finding. A context effect was supported in DES-Taxon scores using multiple regression for the THS but not the Modified Posttraumatic Stress Scale (MPSS-SR; Falsetti, Resnick, Resick, & Kilpatrick, 1993), an effect confirmed with correlation comparisons. Ethnicity influenced the association between measures of trauma and dissociation. Overall, the relation between measures of trauma and dissociation was small to medium, although high correlations were observed between the DES depersonalization/derealization subscale and the Multiscale Dissociation Inventory (Briere, Weathers, & Runtz, 2005) depersonalization and derealization subscales, supporting the construct validity of these measures.

Interparental Violence and the Mediating Role of Parental Availability in Children's Trauma Related Symptoms.

PubMed

Visser, Margreet; Schoemaker, Kim; de Schipper, Clasien; Lamers-Winkelman, Francien; Finkenauer, Catrin

This cross-sectional study examined the hypothesis that parental psychopathology in Interparental Violence (IPV) families crosses over to children, because parental psychopathology spills over to parental functioning. In a high-risk sample of IPV exposed families, we tested whether parental psychopathology spills over to parental availability, which, in turn, shows a crossover effect to children's trauma-related symptoms. The study population consisted of 78 IPV exposed children (4-12 years), and their 65 custodial parents referred to outpatient Children's Trauma Centers in the Netherlands for intervention. Consistent with our hypotheses, parental psychopathology was negatively related to parental availability, suggesting a spillover effect. Although parental psychopathology was not associated with children's trauma-related symptoms directly, we found evidence for the predicted indirect, crossover effects. We found an indirect crossover effect from parental psychopathology to children's trauma-related anxiety, depression, and anger, through the spillover effect of parental availability. Clinical implications for treatment and study limitations are discussed.

Mechanism of Salutary Effects of Astringinin on Rodent Hepatic Injury following Trauma-Hemorrhage: Akt-Dependent Hemeoxygenase-1 Signaling Pathways

Astringinin can attenuate organ injury following trauma-hemorrhage, the mechanism remains unknown. Protein kinase B/hemeoxygenase-1 (Akt/HO-1) pathway exerts potent anti-inflammatory effects in various tissues. The aim of this study is to elucidate whether Akt/HO-1 plays any role in astringinin-mediated attenuation of hepatic injury following trauma-hemorrhage. For study this, male Sprague-Dawley rats underwent trauma-hemorrhage (mean blood pressure 35–40 mmHg for 90 min) followed by fluid resuscitation. A single dose of astringinin (0.3 mg/kg body weight) with or without a PI3K inhibitor (wortmannin) or a HO antagonist (chromium-mesoporphyrin) was administered during resuscitation. Various parameters were measured at 24 h post-resuscitation. Results showed that trauma-hemorrhage increased plasma aspartate and alanine aminotransferases (AST and ALT) concentrations and hepatic myeloperoxidase activity, cytokine induced neutrophil chemoattractant (CINC)-1, CINC-3, intercellular adhesion molecule-1, and interleukin-6 levels. These parameters were significantly improved in the astringinin-treated rats subjected to trauma-hemorrhage. Astringinin treatment also increased hepatic Akt activation and HO-1 expression as compared with vehicle-treated trauma-hemorrhaged rats. Co-administration of wortmannin or chromium-mesoporphyrin abolished the astringinin-induced beneficial effects on post-resuscitation pro-inflammatory responses and hepatic injury. These findings collectively suggest that the salutary effects of astringinin administration on attenuation of hepatic injury after trauma-hemorrhage are likely mediated via Akt dependent HO-1 up-regulation.

Astringinin can attenuate organ injury following trauma-hemorrhage, the mechanism remains unknown. Protein kinase B/hemeoxygenase-1 (Akt/HO-1) pathway exerts potent anti-inflammatory effects in various tissues. The aim of this study is to elucidate whether Akt/HO-1 plays any role in astringinin-mediated attenuation of hepatic injury following trauma-hemorrhage. For study this, male Sprague-Dawley rats underwent trauma-hemorrhage (mean blood pressure 35-40 mmHg for 90 min) followed by fluid resuscitation. A single dose of astringinin (0.3 mg/kg body weight) with or without a PI3K inhibitor (wortmannin) or a HO antagonist (chromium-mesoporphyrin) was administered during resuscitation. Various parameters were measured at 24 h post-resuscitation. Results showed that trauma-hemorrhage increased plasma aspartate and alanine aminotransferases (AST and ALT) concentrations and hepatic myeloperoxidase activity, cytokine induced neutrophil chemoattractant (CINC)-1, CINC-3, intercellular adhesion molecule-1, and interleukin-6 levels. These parameters were significantly improved in the astringinin-treated rats subjected to trauma-hemorrhage. Astringinin treatment also increased hepatic Akt activation and HO-1 expression as compared with vehicle-treated trauma-hemorrhaged rats. Co-administration of wortmannin or chromium-mesoporphyrin abolished the astringinin-induced beneficial effects on post-resuscitation pro-inflammatory responses and hepatic injury. These findings collectively suggest that the salutary effects of astringinin administration on attenuation of hepatic injury after trauma-hemorrhage are likely mediated via Akt dependent HO-1 up-regulation.

The author investigates the effect of retraumatization on the children of Holocaust survivors who have appropriated their parents' trauma through unconscious identification. The author proposes that the working through of the real trauma results in a mitigation of the transmitted trauma in the psychic reality and mobilizes the work of mourning that facilitates the mastery of the real as well as the transmitted trauma. Two case examples are cited as illustration.

BACKGROUND The optimal geographic configuration of health care systems is key to maximizing accessibility while promoting the efficient use of resources. This article reports the use of a novel approach to inform the optimal configuration of a national trauma system. METHODS This is a prospective cohort study of all trauma patients, 15 years and older, attended to by the Scottish Ambulance Service, between July 1, 2013, and June 30, 2014. Patients underwent notional triage to one of three levels of care (major trauma center [MTC], trauma unit, or local emergency hospital). We used geographic information systems software to calculate access times, by road and air, from all incident locations to all candidate hospitals. We then modeled the performance of all mathematically possible network configurations and used multiobjective optimization to determine geospatially optimized configurations. RESULTS A total of 80,391 casualties were included. A network with only high- or moderate-volume MTCs (admitting at least 650 or 400 severely injured patients per year, respectively) would be optimally configured with a single MTC. A network accepting lower-volume MTCs (at least 240 severely injured patients per year) would be optimally configured with two MTCs. Both configurations would necessitate an increase in the number of helicopter retrievals. CONCLUSION This study has shown that a novel combination of notional triage, network analysis, and mathematical optimization can be used to inform the planning of a national clinical network. Scotland’s trauma system could be optimized with one or two MTCs. LEVEL OF EVIDENCE Care management study, level IV. PMID:26335775

An underestimated evaluation of systemic organs in cases with spinal fractures might jeopardize the intervention for treatment and future complications with an increased morbidity and mortality are almost warranted. In the present study, a retrospective analysis of spinal fracture cases associated with systemic trauma was performed to assess surgical success. A retrospective analysis of patients with thoracolumbar fractures who were admitted to the emergency unit between September 2012 and September 2014 was used for the study. The cases were categorized according to age, sex, reason of trauma, associated trauma, neurological condition and treatment details and results were analysed using SPSS 14.0 for Windows. The most common reason of trauma is detected as falls in 101 cases (64.3%). Radiological evaluation of spinal fractures revealed a compression fracture in 106 cases (67.5%) and other fractures in 51 cases (32.5%). Surgical treatment for spinal fracture was performed in 60.5% of the cases and conservative approach was preferred in 39.5% cases. In non-compressive spinal fractures, an associated pathology like head trauma, lower extremity fracture or neurological deficit was found to be higher in incidence (p < 0.05). Necessity for surgical intervention was found to be more prominent in this group (p < 0.05). However, the fracture type was not found to be associated with morbidity and mortality (p < 0.05). A surgical intervention for a spinal fracture necessitating surgery should rather be performed right after stabilization of the systemic condition which might be associated with decreased morbidity and mortality.

Challenges in treating post-traumatic stress disorder and attachment trauma.

PubMed

Allen, Jon G

2003-06-01

Treating women suffering from trauma poses significant challenges. The diagnostic prototype of post-traumatic stress disorder (PTSD) is based on single-event trauma, such as sexual assault in adulthood. Several effective cognitive- behavioral treatments for such traumas have been developed, although many treated patients continue to experience residual symptoms. Even more problematic is the complex developmental psychopathology stemming from a lifetime history of multiple traumas, often beginning with maltreatment in early attachment relationships. A history of attachment trauma undermines the development of capacities to regulate emotional distress and thereby complicates the treatment of acute trauma in adulthood. Such complex trauma requires a multifaceted treatment approach that must balance processing of traumatic memories with strategies to contain the intense emotions this processing evokes. Moreover, conducting such treatment places therapists at risk for secondary trauma such that trauma therapists also must process this stressful experience and implement strategies to regulate their own distress.

Seasonality in trauma admissions - Are daylight and weather variables better predictors than general cyclic effects?

Trauma is a leading global cause of death, and predicting the burden of trauma admissions is vital for good planning of trauma care. Seasonality in trauma admissions has been found in several studies. Seasonal fluctuations in daylight hours, temperature and weather affect social and cultural practices but also individual neuroendocrine rhythms that may ultimately modify behaviour and potentially predispose to trauma. The aim of the present study was to explore to what extent the observed seasonality in daily trauma admissions could be explained by changes in daylight and weather variables throughout the year. Retrospective registry study on trauma admissions in the 10-year period 2001-2010 at Oslo University Hospital, Ullevål, Norway, where the amount of daylight varies from less than 6 hours to almost 19 hours per day throughout the year. Daily number of admissions was analysed by fitting non-linear Poisson time series regression models, simultaneously adjusting for several layers of temporal patterns, including a non-linear long-term trend and both seasonal and weekly cyclic effects. Five daylight and weather variables were explored, including hours of daylight and amount of precipitation. Models were compared using Akaike's Information Criterion (AIC). A regression model including daylight and weather variables significantly outperformed a traditional seasonality model in terms of AIC. A cyclic week effect was significant in all models. Daylight and weather variables are better predictors of seasonality in daily trauma admissions than mere information on day-of-year.

The incidence of wound complications related to negative pressure wound therapy power outage and interruption of treatment in orthopaedic trauma patients.

2011-02-01

Negative pressure wound therapy (NPWT) using the Vacuum Assisted Closure system is an invaluable tool for use on patients with complex limb and soft tissue problems. Recently, the manufacturer (Kinetic Concepts, Inc, San Antonio, TX) made significant modifications to the NPWT platform, including computer software, battery, alarming systems, electric cord and plug apparatus, and others. Since these modifications, we have seen several cases in which the NPWT device has powered off resulting in an unrecognized interruption of therapy. We sought to evaluate the conditions and clinical effects, if any, to orthopaedic trauma patients who experienced an interruption of NPWT therapy when the device powers off. Retrospective study of consecutive patients. Two neighboring regional trauma centers. One hundred twenty-three consecutive orthopaedic trauma patients treated with NPWT by two orthopaedic trauma surgeons between May and November 2008. Patient/injury, treatment, and perioperative clinical outcomes data (with emphasis on wound complications such as infection, graft loss, and unscheduled surgery) were collected from medical records and wound care databases. Twelve patients (10%) had problems with the NPWT device powering off causing an unrecognized interruption of therapy. Eleven patients underwent early (less than 6 hours) wound débridement and reapplication of NPWT after detection, of which nine required unplanned surgery. Seven of the 12 patients recognized as having failed NPWT of this type ultimately experienced wound complications, including five deep infections and both patients being treated with an Integra graft (loss of graft). We have seen substantial problems in orthopaedic trauma patients treated with the NPWT, in which the device has powered off resulting in an unrecognized interruption of therapy. This has resulted in atypically unhealthy-appearing wounds, unplanned surgeries for débridement, and most importantly, an increased incidence of wound complications, including infection and graft loss (P < 0.05).

Using nationally representative data from South Africa, we examine lifetime prevalence of traumas and multiple traumas (number of events). Employing multiple regression analysis, we study sociodemographic risk of trauma, and the association between trauma and distress. Results indicate most South Africans experience at least one traumatic event during their lives, with the majority reporting multiple. Consistent variation in risk is evident for gender and marital status but not other sociodemographics. Trauma is positively related to high distress, and findings also support a cumulative effect of trauma exposure. Individuals with the most traumas (6+) appear at five- times greater risk of high distress. This study highlights the importance of considering traumatic events in the context of other traumas in South Africa. PMID:17955545

Effect of gender and sex hormones on immune responses following shock.

Angele, M K; Schwacha, M G; Ayala, A; Chaudry, I H

2000-08-01

Several clinical and experimental studies show a gender dimorphism of the immune and organ responsiveness in the susceptibility to and morbidity from shock, trauma, and sepsis. In this respect, cell-mediated immune responses are depressed in males after trauma-hemorrhage, whereas they are unchanged or enhanced in females. Sex hormones contribute to this gender-specific immune response after adverse circulatory conditions. Specifically, studies indicate that androgens are responsible for the immunodepression after trauma-hemorrhage in males. In contrast, female sex steroids seem to exhibit immunoprotective properties after trauma and severe blood loss, because administration of estrogen prevents the androgen-induced immunodepression in castrated male mice. Nonetheless, the precise underlying mechanisms for these immunomodulatory effects of sex steroids after shock remain unknown. Although testosterone depletion, testosterone receptor antagonism, or estrogen treatment has been shown to prevent the depression of immune functions after trauma-hemorrhage, it remains to be established whether differences in the testosterone-estradiol ratio are responsible for the immune dysfunction. Furthermore, sex hormone receptors have been identified on various immune cells, suggesting direct effects. Thus, the immunomodulatory properties of sex hormones after trauma-hemorrhage might represent novel therapeutic strategies for the treatment of immunodepression in trauma patients.

Trauma Evaluation and Management course was designed to develop trauma cognitive skills in senior medical students. Its effectiveness has been demonstrated in many regions, except in Latin America, where it has been poorly studied. The objective was to determine the Trauma Evaluation and Management course effectiveness, and whether greater effectiveness is achieved in basic- or clinic-cycle students, as well as student perception. Descriptive, observational, longitudinal and prospective study. Two tests were performed, pre- and post-course; the manual was read by the students prior to both tests. Students were divided into 2 groups: group A (consisting of 71 basic-cycle medical students) and group B (consisting of 44 clinical-cycle medical students). Group A achieved a 2.45 increase (p<0.01) in the post-course evaluation compared with pre-course test. Group B increased the mean score by 2.25 (p>0.05) from pre- to post-course tests. There was a significant difference between groups in both evaluations (pre-course test p<0.01 and post-course test p>0.05), with no difference in improvement (p>0.05). Using a questionnaire, 92.17% of the students totally agreed that the course improved their trauma knowledge, 76.52% that it increased their trauma clinical skills, with 94.78% being totally satisfied with the course, and 86.09% totally agreed that Trauma Evaluation and Management course should be in Medicine curriculum. Trauma Evaluation and Management course improves trauma cognitive skills, and undergraduate medical students in Mexico broadly accept it. Copyright © 2015 Academia Mexicana de Cirugía A.C.

Though the US civilian trauma care system plays a critical role in disaster response, there is currently no systems-based strategy that enables hospital emergency management and local and regional emergency planners to quantify, and potentially prepare for, surges in trauma care demand that accompany mass-casualty disasters. A proof-of-concept model that estimates the geographic distributions of patients, trauma center resource usage, and mortality rates for varying disaster sizes, in and around the 25 largest US cities, is presented. The model was designed to be scalable, and its inputs can be modified depending on the planning assumptions of different locales and for different types of mass-casualty events. To demonstrate the model's potential application to real-life planning scenarios, sample disaster responses for 25 major US cities were investigated using a hybrid of geographic information systems and dynamic simulation-optimization. In each city, a simulated, fast-onset disaster epicenter, such as might occur with a bombing, was located randomly within one mile of its population center. Patients then were assigned and transported, in simulation, via the new model to Level 1, 2, and 3 trauma centers, in and around each city, over a 48-hour period for disaster scenario sizes of 100, 500, 5000, and 10,000 casualties. Across all 25 cities, total mean mortality rates ranged from 26.3% in the smallest disaster scenario to 41.9% in the largest. Out-of-hospital mortality rates increased (from 21.3% to 38.5%) while in-hospital mortality rates decreased (from 5.0% to 3.4%) as disaster scenario sizes increased. The mean number of trauma centers involved ranged from 3.0 in the smallest disaster scenario to 63.4 in the largest. Cities that were less geographically isolated with more concentrated trauma centers in their surrounding regions had lower total and out-of-hospital mortality rates. The nine US cities listed as being the most likely targets of terrorist attacks involved, on average, more trauma centers and had lower mortality rates compared with the remaining 16 cities. The disaster response simulation model discussed here may offer insights to emergency planners and health systems in more realistically planning for mass-casualty events. Longer wait and transport times needed to distribute high numbers of patients to distant trauma centers in fast-onset disasters may create predictable increases in mortality and trauma center resource consumption. The results of the modeled scenarios indicate the need for a systems-based approach to trauma care management during disasters, since the local trauma center network was often too small to provide adequate care for the projected patient surge. Simulation of out-of-hospital resources that might be called upon during disasters, as well as guidance in the appropriate execution of mutual aid agreements and prevention of over-response, could be of value to preparedness planners and emergency response leaders. Study assumptions and limitations are discussed. Carr BG , Walsh L , Williams JC , Pryor JP , Branas CC . A geographic simulation model for the treatment of trauma patients in disasters.

To evaluate the epidemiological aspects, behavior, morbidity and treatment outcomes for liver trauma. We conducted a retrospective study of patients over 13 years of age admitted to a university hospital from 1990 to 2010, submitted to surgery or nonoperative management (NOM). 748 patients were admitted with liver trauma. The most common mechanism of injury was penetrating trauma (461 cases, 61.6%), blunt trauma occurring in 287 patients (38.4%). According to the degree of liver injury (AAST-OIS) in blunt trauma we predominantly observed Grades I and II and in penetrating trauma, Grade III. NOM was performed in 25.7% of patients with blunt injury. As for surgical procedures, suturing was performed more frequently (41.2%). The liver-related morbidity was 16.7%. The survival rate for patients with liver trauma was 73.5% for blunt and 84.2% for penetrating trauma. Mortality in complex trauma was 45.9%. trauma remains more common in younger populations and in males. There was a reduction of penetrating liver trauma. NOM proved safe and effective, and often has been used to treat patients with penetrating liver trauma. Morbidity was high and mortality was higher in victims of blunt trauma and complex liver injuries.

This study introduces a new coding system, the Coding and Assessment System for Narratives of Trauma (CASNOT), to analyse several language domains in narratives of autobiographical memories, especially in trauma narratives. The development of the coding system is described. It was applied to assess positive and traumatic/negative narratives in 50 battered women (trauma-exposed group) and 50 nontrauma-exposed women (control group). Three blind raters coded each narrative. Inter-rater reliability analyses were conducted for the CASNOT language categories (multirater Kfree coefficients) and dimensions (intraclass correlation coefficients). High levels of inter-rater agreement were found for most of the language domains. Categories that did not reach the expected reliability were mainly those related to cognitive processes, which reflects difficulties in operationalizing constructs such as lack of control or helplessness, control or planning, and rationalization or memory elaboration. Applications and limitations of the CASNOT are discussed to enhance narrative measures for autobiographical memories.

Collection and analysis of up-to-date and accurate injury surveillance data are a key step in the maturation of trauma systems. Trauma registries have proven to be difficult to establish in low- and middle-income countries owing to the burden of trauma volume, cost, and complexity. To determine whether an electronic trauma health record (eTHR) used by physicians can serve as simultaneous clinical documentation and data acquisition tools. This 2-part quality improvement study included (1) preimplementation and postimplementation eTHR study with assessments of satisfaction by 41 trauma physicians, time to completion, and quality of data collected comparing paper and electronic charting; and (2) prospective ecologic study describing the burden of trauma seen at a Level I trauma center, using real-time data collected by the eTHR on consecutive patients during a 12-month study period. The study was conducted from October 1, 2010, to September 30, 2011, at Groote Schuur Hospital, Cape Town, South Africa. Data analysis was performed from October 15, 2011, to January 15, 2013. The primary outcome of part 1 was data field competition rates of pertinent trauma registry items obtained through electronic or paper documentation. The main measures of part 2 were to identify risk factors to trauma in Cape Town and quality indicators recommended for trauma system evaluation at Groote Schuur Hospital. The 41 physicians included in the study found the electronic patient documentation to be more efficient and preferable. A total of 11 612 trauma presentations were accurately documented and promptly analyzed. Fields relevant to injury surveillance in the eTHR (n = 11 612) had statistically significant higher completion rates compared with paper records (n = 9236) (for all comparisons, P < .001). The eTHR successfully captured quality indicators recommended for trauma system evaluation which were previously challenging to collect in a timely and accurate manner. Of the 11 612 patient admissions over the study period, injury location was captured 11 075 times (95.4%), injury mechanism 11 135 times (95.9%), systolic blood pressure 11 106 times (95.6%), and Glasgow Coma Scale 11 140 times (95.9%). These fields were successfully captured with statistically higher rates than previous paper documentation. Epidemiologic analysis confirmed a heavy burden of violence-related injury (51.8% of all injuries) and motor vehicle crash injuries (14.3% of all injuries). Mapping analysis demonstrated clusters of injuries originating mainly from vulnerable and low-income neighborhoods and their respective referring trauma facilities, Mitchell's Plain Hospital (734 [10.1%]), Guguletu Community Health Center (654 [9.0%]), and New Somerset Hospital (400 [5.5%]). Accurate capture and simultaneous analysis of trauma data in low-resource trauma settings are feasible through the integration of surveillance into clinical workflow and the timely analysis of electronic data.

Evaluation, development, and implementation of trauma systems in Latin America are challenging undertakings as no model is currently in place that can be easily replicated throughout the region. The use of teleconferencing has been essential in overcoming other challenges in the medical field and improving medical care. This article describes the use of international videoconferencing in the field of trauma and critical care as a tool to evaluate differences in care based on local resources, as well as facilitating quality improvement and system development in Latin America. In February 2009, the International Trauma and Critical Care Improvement Project was created and held monthly teleconferences between U.S. trauma surgeons and Latin American general surgeons, emergency physicians, and intensivists. In-depth discussions and prospective evaluations of each case presented were conducted by all participants based on resources available. Care rendered was divided in four stages: (1) pre-hospital setting, (2) emergency room or trauma room, (3) operating room, and (4) subsequent postoperative care. Furthermore, the participating institutions completed an electronic survey of trauma resources based on World Health Organization/International Association for Trauma and Surgical Intensive Care guidelines. During a 17-month period, 15 cases in total were presented from a Level I and a Level II U.S. hospital (n=3) and five Latin American hospitals (n=12). Presentations followed the Advanced Trauma Life Support sequence in all U.S. cases but in only 3 of the 12 Latin American cases. The following deficiencies were observed in cases presented from Latin America: pre-hospital communication was nonexistent in all cases; pre-hospital services were absent in 60% of cases presented; lack of trauma team structure was evident in the emergency departments; during the initial evaluation and resuscitation, the Advanced Trauma Life Support protocol was followed one time and the Clinical Randomization of an Antifibrinolytic in Significant Hemorrhage protocol on two occasions; it was determined that imaging resources were adequately used in half of the cases; the initial care was mostly provided by emergency room physicians; and a surgeon, operating room, and intensive care unit were not readily available 83% of the time. The ease of patient flow was cumbersome because of a lack of a structured system for trauma care except for one academic urban center. Adequate trauma resources are present in less than 50% of the time. Multidisciplinary resources, quality improvement programs, protocols, and guidelines were deficient. A well-structured international teleconference can be used as a dynamic window of observation to evaluate and identify deficiencies in trauma care in the Latin American region. These findings can be used to formulate specific recommendations based on local resources. Furthermore, by raising local awareness, leaders could be identified to become the executors of more efficient healthcare policies that can potentially affect trauma care.

We aimed to investigate the relation of trauma profile to schizophrenia psychopathology in a sample of Egyptian drug-naïve adolescent patients with first-episode schizophrenia. In addition, a hypothesized mediating effect of brain-derived neurotrophic factor (BDNF) in this relation was formally tested. We assessed 74 eligible outpatients using the Positive and Negative Syndrome Scale (PANSS) for measuring psychopathology. Trauma histories were recorded with the help of the Cumulative Trauma Measure. Serum BDNF levels were estimated by enzyme-linked immunosorbent assay. Total cumulative trauma, personal identity trauma, and survival trauma were found to be the significant predictors for schizophrenia psychopathology. BDNF fully mediated the associations between total cumulative trauma and overall schizophrenia psychopathology. BDNF also mediated the associations between some types of trauma and both PANSS-positive and PANSS-negative symptom factors. We concluded that total cumulative trauma and certain trauma types are linked with schizophrenia psychopathology. BDNF appears to mediate these links.

Prehospital care for multiple trauma patients in Germany.

PubMed

Maegele, Marc

2015-01-01

For the German speaking countries, Tscherne's definition of "polytrauma" which represents an injury of at least two body regions with one or a combination being life-threatening is still valid. The timely and adequate management including quick referral of the trauma patient into a designated trauma center may limit secondary injury and may thus improve outcomes already during the prehospital phase of care. The professional treatment of multiple injured trauma patients begins at the scene in the context of a well structured prehospital emergency medical system. The "Primary Survey" is performed by the emergency physician at the scene according to the Prehospital Trauma Life Support (PHTLS)-concept. The overall aim is to rapidly assess and treat life-threatening conditions even in the absence of patient history and diagnosis ("treat-first-what-kills-first"). If no immediate treatment is necessary, a "Secondary Sur- vey" follows with careful and structured body examination and detailed assessment of the trauma mechanism. Massive and life-threatening states of hemorrhage should be addressed immediately even disregarding the ABCDE-scheme. Critical trauma patients should be referred without any delay ("work and go")toTR-DGU® certified trauma centers of the local trauma networks. Due to the difficult pre- hospital environment the number of quality studies in the field is low and, as consequence, the level of evidence for most recommendations is also low. Much information has been obtained from different care systems and the interchangeability of results is limited. The present article provides a synopsis of rec- ommendations for early prehospital care for the severely injured based upon the 2011 updated multi- disciplinary S3-Guideline "Polytrauma/Schwerstverletzten Behandlung", the most recently updated European Trauma guideline and the current PHTLS-algorithms including grades of recommendation whenever possible.

Alcohol use disorder (AUD) is debilitating and costly. Identification and better understanding of risk factors influencing the development of AUD remain a research priority. Although early life exposure to trauma increases the risk of adulthood psychiatric disorders, including AUD, many individuals exposed to early life trauma do not develop psychopathology. Underlying genetic factors may contribute to differential sensitivity to trauma experienced in childhood. The hypothalamic-pituitary-adrenal (HPA) axis is susceptible to long-lasting changes in function following childhood trauma. Functional genetic variation within FKBP5, a gene encoding a modulator of HPA axis function, is associated with the development of psychiatric symptoms in adulthood, particularly among individuals exposed to trauma early in life. In the current study, we examined interactions between self-reported early life trauma, past-year life stress, past-year trauma, and a single nucleotide polymorphism (rs1360780) in FKBP5 on heavy alcohol consumption in a sample of 1,845 college students from two university settings. Although we found no effect of early life trauma on heavy drinking in rs1360780*T-allele carriers, rs1360780*C homozygotes exposed to early life trauma had a lower probability of heavy drinking compared to rs1360780*C homozygotes not exposed to early life trauma (P < 0.01). The absence of an interaction between either current life stress or past-year trauma, and FKBP5 genotype on heavy drinking suggests that there exists a developmental period of susceptibility to stress that is moderated by FKBP5 genotype. These findings implicate interactive effects of early life trauma and FKBP5 genetic variation on heavy drinking. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Globally, the compliance of resident work-hour restrictions has no impact on trauma outcome. However, the effect of protected education time (PET), during which residents are unavailable to respond to trauma patients, has not been studied. We hypothesized that PET has no impact on the outcome of trauma patients. We conducted a retrospective review of relevant patients at an academic level I trauma center. During PET, a trauma attending and advanced practice providers (APPs) responded to trauma activations. PGY1, 3, and 4 residents were also available at all other times. The outcome of new trauma patient activations during Thursday morning 3-hours resident PET was compared with same time period on other weekdays (non-PET) using a univariate and multivariate analysis. From January 2005 to April 2010, a total of 5968 trauma patients were entered in the registry. Of these, 178 patients (2.98%) were included for study (37 PET and 141 non-PET). The mean injury severity score (ISS) was 16.2. Although no significant difference were identified in mortality, complications, or length of stay (LOS), we do see that length of emergency department stay (ED-LOS) tends to be longer during PET, although not significantly (314 vs 381 minutes, p = 0.74). On the multiple logistic regression model, PET was not a significant factor of complications, LOS, or ED-LOS. Few trauma activations occur during PET. New trauma activations can be staffed safely by trauma activations and APPs. However, there could be some delays in transferring patients to appropriate disposition. Additional study is required to determine the effect of PET on existing trauma inpatients. Copyright © 2012 Association of Program Directors in Surgery. Published by Elsevier Inc.

A functional promoter polymorphism in the monoamine oxidase A (MAOA) gene has been implicated in neuropsychiatric disorders and also moderates the association between early-life stress and mental disorders, which often co-occur with cardiovascular disease. No study has examined the relationship between MAOA genotype, childhood trauma, and subclinical atherosclerosis. The objective of this investigation was to examine whether childhood trauma moderates the association between MAOA genotype and subclinical atherosclerosis. A sample including 289 middle-aged male twin pairs was studied. Subclinical atherosclerosis was assessed by brachial flow-mediated dilation (FMD) using ultrasound. Childhood trauma, before age 18 years, was measured with the Early Trauma Inventory and included physical, emotional, and sexual abuse as well as general trauma. Generalized estimating equation models were used to test the main and interactive effects of the MAOA genotype and each domain of childhood trauma on FMD, adjusting for known risk factors. General trauma was the most prevalent childhood trauma (28.4%), followed by physical abuse (25.0%), emotional abuse (19.4%), and sexual abuse (11.6%). MAOA genotype was not associated with any domain of childhood trauma. There was no significant evidence for a main effect for the MAOA genotype (β = .02, p = .82) or childhood trauma (.005 < β < .10, p > .54) FMD. However, a significant interaction was observed between MAOA genotype and physical (β interaction = .37, p = .026) or emotional abuse (β interaction = .43, p = .025) on subclinical atherosclerosis. Childhood trauma modulates the impact of MAOA variant on subclinical atherosclerosis, independent of traditional cardiovascular risk factors.

Approximately 10% of trauma-exposed individuals go on to develop post-traumatic stress disorder (PTSD). Neural emotion regulation may be etiologically involved in PTSD development. Oxytocin administration early post-trauma may be a promising avenue for PTSD prevention, as intranasal oxytocin has previously been found to affect emotion regulation networks in healthy individuals and psychiatric patients. In a randomized double-blind placebo-controlled between-subjects functional magnetic resonance (fMRI) study, we assessed the effects of a single intranasal oxytocin administration (40 IU) on seed-based amygdala resting-state FC with emotion regulation areas (ventromedial prefrontal cortex (vmPFC), ventrolateral prefrontal cortex (vlPFC)), and salience processing areas (insula, dorsal anterior cingulate cortex (dACC)) in 37 individuals within 11 days post trauma. Two resting-state scans were acquired; one after neutral- and one after trauma-script-driven imagery. We found that oxytocin administration reduced amygdala-left vlPFC FC after trauma script-driven imagery, compared with neutral script-driven imagery, whereas in PL-treated participants enhanced amygdala-left vlPFC FC was observed following trauma script-driven imagery. Irrespective of script condition, oxytocin increased amygdala-insula FC and decreased amygdala-vmPFC FC. These neural effects were accompanied by lower levels of sleepiness and higher flashback intensity in the oxytocin group after the trauma script. Together, our findings show that oxytocin administration may impede emotion regulation network functioning in response to trauma reminders in recently trauma-exposed individuals. Therefore, caution may be warranted in administering oxytocin to prevent PTSD in distressed, recently trauma-exposed individuals.

Vicarious traumatization, secondary traumatic stress, and burnout in sexual assault and domestic violence agency staff.

This study investigated three occupational hazards of therapy with trauma victims: vicarious trauma and secondary traumatic stress (or "compassion fatigue"), which describe therapists' adverse reactions to clients' traumatic material, and burnout, a stress response experienced in many emotionally demanding "people work" jobs. Among 101 trauma counselors, client exposure workload and being paid as a staff member (vs. volunteer) were related to burnout sub-scales, but not as expected to overall burnout or vicarious trauma, secondary traumatic stress, or general distress. More educated counselors and those seeing more clients reported less vicarious trauma. Younger counselors and those with more trauma counseling experience reported more emotional exhaustion. Findings have implications for training, treatment, and agency support systems.

The United States has achieved unprecedented survival rates, as high as 98%, for casualties arriving alive at the combat hospital. Our military medical personnel are rightly proud of this achievement. Commanders and Servicemembers are confident that if wounded and moved to a Role II or III medical facility, their care will be the best in the world. Combat casualty care, however, begins at the point of injury and continues through evacuation to those facilities. With up to 25% of deaths on the battlefield being potentially preventable, the prehospital environment is the next frontier for making significant further improvements in battlefield trauma care. Strict adherence to the evidence-based Tactical Combat Casualty Care (TCCC) Guidelines has been proven to reduce morbidity and mortality on the battlefield. However, full implementation across the entire force and commitment from both line and medical leadership continue to face ongoing challenges. This report on prehospital trauma in the Combined Joint Operations Area?Afghanistan (CJOA-A) is a follow-on to the one previously conducted in November 2012 and published in January 2013. Both assessments were conducted by the US Central Command (USCENTCOM) Joint Theater Trauma System (JTTS). Observations for this report were collected from December 2013 to January 2014 and were obtained directly from deployed prehospital providers, medical leaders, and combatant leaders. Significant progress has been made between these two reports with the establishment of a Prehospital Care Division within the JTTS, development of a prehospital trauma registry and weekly prehospital trauma conferences, and CJOA-A theater guidance and enforcement of prehospital documentation. Specific prehospital trauma-care achievements include expansion of transfusion capabilities forward to the point of injury, junctional tourniquets, and universal approval of tranexamic acid. 2015.

The impact of the Trauma Collaborative Care (TCC) program on surgeon confidence in managing the psychosocial sequelae of orthopaedic trauma was evaluated as part of a larger prospective, multisite, cluster clinical trial. We compared confidence and perceived resource availability among surgeons practicing in trauma centers that implemented the TCC program with orthopaedic trauma surgeons in similar trauma centers that did not implement the TCC. Prospective cohort design. Level-I trauma centers. Attending surgeons and fellows (N = 95 Pre and N = 82 Post). Self-report 10-item measure of surgeon confidence in managing psychosocial issues associated with trauma and perceived availability of support resources. Analyses, performed on the entire sample and repeated on the subset of 52 surgeons who responded to the survey at both times points, found surgeons at intervention sites experienced a significantly greater positive improvement (P < 0.05) in their (1) belief that they have strategies to help orthopaedic trauma patients change their psychosocial situation; (2) confidence in making appropriate referrals for orthopaedic trauma patients with psychosocial problems; and (3) belief that they have access to information to guide the management of psychosocial issues related to recovery. Initial data suggest that the establishment of the TCC program can improve surgeons' perceived availability of resources and their confidence in managing the psychosocial sequelae after injury. Further studies will be required to determine if this translates into beneficial patient effects. Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

Childhood trauma has been found to be a critical risk factor for depression in adolescents. Personality traits have been linked with mental health. However, the relationship between childhood trauma, personality traits, and depressive symptoms in adolescents is largely unclear. This study tried to examine the mediating effect of personality traits between childhood trauma and depressive symptoms among adolescents. Meanwhile, the possible bidirectional association between personality traits and depression was considered in the study. A group of community-based adolescents aged 10-17 years (N = 5793) were recruited from nine schools in Wuhan city, China. The participants completed self-report questionnaires, including the Center for Epidemiologic Studies Depression Scale (CES-D), the Childhood Trauma Questionnaire (CTQ) and the NEO-Five Factor Inventory (NEO-FFI). Results showed that childhood trauma experiences were positively related with depressive symptoms and neuroticism, and negatively related with extraversion and conscientiousness; depressive symptoms were related with high neuroticism, low extraversion, and conscientiousness. Neuroticism and extraversion partially mediated the relationship between childhood trauma and depressive symptoms. And 'childhood trauma-personality traits-depression' models showed better property than the alternative models of 'childhood trauma-depression-personality traits'. The current study provides preliminary evidence for mediation roles of neuroticism and extraversion in the effect of childhood trauma to depressive symptoms in adolescents. These findings may contribute to better prevention and interventions for depressive symptoms among adolescents with childhood trauma via personality traits improvement. Copyright © 2018.

To evaluate the effect of rescue transesophageal echocardiography (TEE) on the management of trauma patients, we reviewed imaging and charts of unstable trauma patients at a level I trauma center. Critical rescue TEE findings included acute right ventricular failure, stress cardiomyopathy, type B aortic dissection, mediastinal air, and dynamic left ventricular outflow tract obstruction. Left ventricular filling was classified as low (underfilled) in 57% of all cases. Rescue TEE revealed a variety of new diagnoses and led to a change in resuscitation strategy about half of the time.

2017-08-01

Greater risk of post-traumatic stress disorder (PTSD) is seen in individuals exposed to interpersonal traumatic events. Based on an attachment perspective, interpersonal trauma exposure may activate one's attachment insecurity system and disrupt affect, behaviour and interpersonal function, which may in turn create more difficulties to cope with interpersonal traumas and exacerbate PTSD symptomatology. The present study examined whether attachment anxiety relative to attachment avoidance would be a stronger predictor of greater PTSD symptoms following interpersonal traumas versus impersonal traumas in a Taiwanese sample. One hundred and sixty-two trauma-exposed Taiwanese young adults completed the measures of symptoms of depression, anxiety and PTSD, and attachment anxiety and attachment avoidance. In this Taiwanese study, higher attachment anxiety was observed in individuals who were exposed to interpersonal traumas. The interpersonal trauma group reported greater PTSD symptoms than did the impersonal trauma group. Specifically, after controlling for age, occurrence of trauma and distress of trauma, attachment anxiety, but not attachment avoidance, predicted more PTSD total severity and avoidance symptoms in the interpersonal trauma group. The findings may be pertinent to attachment anxiety-related hyperactivating strategies, as well as specific cultural values and a forbearance strategy applied to regulate traumatic distress in a collectivist society.

To examine various clinical factors for their ability to predict mortality in geriatric patients following blunt trauma. In this retrospective study, trauma registries and medical records from three trauma centers were reviewed for patients 65 years and older who had sustained blunt trauma. The following variables were extracted and examined independently and in combination for their ability to predict death: age, gender, mechanism of injury, admission blood pressure, and Glasgow Coma Scale score, respiratory status, Trauma Score, Revised Trauma Score, and Injury Severity Score. Three urban trauma centers. Geriatric trauma patients entering three trauma centers (Stanford [Calif] University Hospital, Vanderbilt University Medical Center, Nashville, Tenn, and Maryland Institute for Emergency Medical Services Systems, Baltimore) following blunt trauma during a 7-year period (1982 to 1989). The Injury Severity Score was the single variable that correlated most significantly with mortality. Mortality rates were higher for men than for women and were significantly higher in patients 75 years and older. Admission variables associated with the highest relative risks of death included a Trauma Score less than 7; hypotension (systolic blood pressure, < 90 mm Hg); hypoventilation (respiratory rate, < 10 breaths per minute); or a Glasgow Coma Scale score equal to 3. Admission variables in geriatric trauma patients can be used to predict outcome and may also be useful in making decisions about triage, quality assurance, and use of intensive care unit beds.

To determine whether the prevalence of physical comorbidities in Australian Vietnam War veterans with post-traumatic stress disorder (PTSD) is higher than in trauma-exposed veterans without PTSD. Cross-sectional analysis of the health status (based on self-reported and objective clinical assessments) of 298 Australian Vietnam War veterans enrolled by the Gallipoli Medical Research Institute (Brisbane) during February 2014 - July 2015, of whom 108 were confirmed as having had PTSD and 106 served as trauma-exposed control participants.Main outcomes and measures: Diagnostic psychiatric interview and psychological assessments determined PTSD status, trauma exposure, and comorbid psychological symptoms. Demographic data, and medical and sleep history were collected; comprehensive clinical examination, electrocardiography, spirometry, liver transient elastography, and selected pathology assessments and diagnostic imaging were performed. Outcomes associated with PTSD were identified; regression analysis excluded the effects of potentially confounding demographic and risk factors and comorbid symptoms of depression and anxiety. The mean total number of comorbidities was higher among those with PTSD (17.7; SD, 6.1) than in trauma-exposed controls (14.1; SD, 5.2; P < 0.001). For 24 of 171 assessed clinical outcomes, morbidity was greater in the PTSD group, including for conditions of the gastrointestinal, hepatic, cardiovascular, and respiratory systems, sleep disorders, and laboratory pathology measures. In regression analyses including demographic factors, PTSD remained positively associated with 17 adverse outcomes; after adjusting for the severity of depressive symptoms, it remained significantly associated with ten. PTSD in Australian Vietnam veterans is associated with comorbidities in several organ systems, independent of trauma exposure. A comprehensive approach to the health care of veterans with PTSD is needed.

Some effects of mechanical trauma on the development of primary cancers and their metastases.

Posttraumatic inflammation and, much less commonly, mechanical trauma itself may affect the clinical course of cancer. There is no evidence that a single incident of trauma can cause cancer, although posttraumatic chronic inflammation may be associated with carcinogenesis. In patients with cancer at the time of trauma, inflammation and repair processes may inhibit or enhance cancer growth, and trauma and its sequelae may increase the rates of invasion and dissemination.

The effectiveness of mental health interventions such as trauma-focused cognitive behavioral therapy (TF-CBT) may vary by client, caregiver, and intervention-level variables, but few randomized trials in low- and middle-income countries (LMIC) have conducted moderation analyses to investigate these characteristics. This study explores moderating factors to TF-CBT treatment response among a sample of orphans and vulnerable children (OVC) in Zambia. Data were obtained from a completed randomized trial of TF-CBT among 257 OVC in Zambia. Trauma symptoms and functioning were measured at baseline and following the end of treatment. Mixed effects regression models were estimated for each moderator of interest: gender, age, number of trauma types experienced, history of sexual abuse, orphan status, primary caretaker, school status, and parental involvement in treatment. Treatment effectiveness was moderated by history of sexual abuse with greater reductions in both outcomes (trauma, p < .05; functioning, p < .01) for those that experienced sexual abuse. Primary caretaker was also a moderator with greater trauma reductions in those who identified their mother as the primary caretaker (p < .01), and better functioning in those that identified their father as the primary caretaker (p < .05). Nonorphans and single orphans (mother alive) showed greater reduction in functional impairment (p < .01) compared with double orphans. There was no significant moderator effect found by gender, age, number of trauma types, school status, or caregiver participation in treatment. This study suggests that TF-CBT was effective in reducing trauma symptoms and functional impairment among trauma-affected youth overall and that it may be particularly effective for survivors of child sexual abuse and children whose primary caretaker is a biological parent. Scale-up of TF-CBT is warranted given the wide range of effectiveness and prevalence of child sexual abuse. Future randomized trials of interventions in LMIC should power for moderation analyses in the study design phase when feasible. © 2016 Association for Child and Adolescent Mental Health.

Childhood trauma is an important factor in adverse mental health outcomes, including depression and anxiety. The purpose of the present study was to evaluate a hypothesized model describing a pathway of childhood trauma and its influence on psychiatric symptoms in patients with depressive disorder. In this model, childhood trauma was positively associated with current depression and anxiety symptoms, which were mediated by a cognitive emotional regulation strategy. Patients with depressive disorder (n=585, 266 men, 316 women) completed the Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Childhood Trauma Questionnaire (CTQ), and Cognitive Emotion Regulation Questionnaire (CERQ). We divided the cognitive emotion regulation strategies into adaptive and maladaptive strategies using a CERQ subscore. We employed structural equation modeling (SEM) and simple/multiple mediation analyses. The indirect effect of maladaptive strategies was significant in the relationship between overall childhood trauma and depression/anxiety severity, whereas the mediation effect of adaptive strategies was limited to depressive symptoms. With respect to specific types of trauma, maladaptive strategies mediated the association between emotional abuse and current depression/anxiety, while the mediation effect of adaptive strategies was limited to emotional neglect. This study's cross-sectional design does not allow establishment of causal relationships. Childhood trauma recall bias may be possible. These findings support the hypothesized model in which childhood trauma is associated with adulthood depression/anxiety symptoms in clinical samples, and mediated by emotion regulation strategies. These results suggest that cognitive emotion dysregulation is an important factor affecting depression/anxiety symptoms in patients with childhood trauma. Copyright © 2017 Elsevier B.V.

Children's behavioral health needs and satisfaction and commitment of foster and adoptive parents: Do trauma-informed services make a difference?

PubMed

Barnett, Erin R; Cleary, Sarah E; Butcher, Rebecca L; Jankowski, Mary K

2018-05-03

Caring for children in foster or adoptive care with behavioral health needs can severely stress parents, contributing to adverse outcomes for children and families. Trauma-informed services from the child welfare and mental health sectors may help prevent poor outcomes by helping children and parents identify and understand trauma and its impact on children's behavioral health and receive effective treatment. To help understand the role of trauma-informed services for the child welfare population, we examined whether trauma-informed child welfare and mental health services moderated the relationship between children's behavioral health needs and parent satisfaction and commitment. The researchers analyzed data from a cross-sectional statewide survey of foster and adoptive parents (n = 512 respondents, 42% of 1,206 contacted) from one state. Foster (but not adoptive) parent ratings of trauma-informed mental health services significantly moderated the relationship between children's behavioral health needs and foster and adoptive parent satisfaction and commitment. As ratings of trauma-informed mental health services increased, the association between child behavioral health needs and parent satisfaction and commitment became nonsignificant, suggesting a buffering effect. Trauma-informed child welfare services did not moderate the relationship for foster or adoptive parents. Leaders and policymakers are urged to promote trauma-informed mental health services for children involved with child welfare to potentially buffer foster parents against lower parenting satisfaction and commitment. More research is needed to replicate and expand on these findings and to examine the effectiveness of trauma-informed services on other relevant child and family outcomes.

1994-05-01

To identify and prioritize research questions of importance to trauma patient care and of interest to trauma nurses. A three-round Delphi technique was used to solicit, identify, and prioritize problems for trauma nursing research. In round 1, experienced trauma nurses (N = 208) generated 513 problems, which were analyzed, categorized, and collapsed into 111 items for subsequent rounds. Round 2 participants rated each research question on a 1 to 7 scale on two criteria: impact on patient welfare and value for practicing nurses. Group median scores provided by 166 round 2 respondents and respondents' individual round 2 scores were indicated on the round 3 questionnaire. Subjects rated the questions again on the same criteria and indicated whether nurses, independently or in collaboration with other health professionals, should assume responsibility for that research. Median and mean scores and rank order were determined for each item. Respondents who completed all three rounds (n = 137) had a mean of 8.3 years of trauma experience. Nine research questions ranked within the top 20 on both criteria. The two research questions that ranked highest on both criteria were: What are the most effective nursing interventions in the prevention of pulmonary and circulatory complications in trauma patients? and What are the most effective methods for preventing aspiration in trauma patients during the postoperative phase? The third-ranked question regarding patient welfare was: What psychological and lifestyle changes result from traumatic injury? Regarding value for practicing nurses, What are the most effective educational methods to prepare and maintain proficiency in trauma care providers? ranked third. These research priorities provide impetus and direction for nursing and collaborative investigation in trauma care.

Melatonin therapy for blunt trauma and strenuous exercise: A mechanism involving cytokines, NFκB, Akt, MAFBX and MURF-1.

Maarman, Gerald J; Reiter, Russel J

2018-08-01

Muscle injury occurs due to trauma, strenuous exercise or sports activities; most people affected are athletes. Ineffectively treated muscle injury can negatively affect sports careers and quality of life after retirement from sports. Reports have indicated that the current therapeutic management of muscle injury, particularly anti-inflammatory drugs, are not necessarily effective. Therefore, better therapies are required. Accumulating evidence has demonstrated melatonin's potent antioxidant and anti-inflammatory actions against muscle pathology in sarcopenia or atrophy in systemic disease. However, the underlying mechanisms for the protective effect of melatonin in the context of trauma/strenuous exercise are multifactorial and not well described. This paper reviews data on melatonin's impact on muscle injury and findings that points toward the mechanisms through which melatonin achieves muscle protection. The general concept described in this review is that melatonin inhibits NFκB, reduces cytokine expression, increases Akt that downregulates the ratio of MAF BX and MURF-1 in order to limit the extent of muscle injury and promote muscle recovery post-injury. The work discussed in this review supports the notion that melatonin may be considered a possible therapy against trauma/sports related muscle injury. Inclusion of melatonin as a therapy in sports medicine could therefore provide a better treatment option for injured athletes and sports individuals.

Background Perineal pain is common after childbirth. We studied the effect of genital tract trauma, labor care, and birth variables on the incidence of pain in a population of healthy women exposed to low rates of episiotomy and operative delivery. Methods A prospective study of genital trauma at birth and assessment of postpartum perineal pain and analgesic use was conducted in 565 midwifery patients. Perineal pain was assessed using the Present Pain Intensity (PPI) and Visual Analog Scale (VAS) components of the validated short form McGill pain scale. Multivariate logistic regression examined which patient characteristics or labor care measures were significant determinants of perineal pain and use of analgesic medicines. Results At hospital discharge, women with major trauma reported higher VAS pain scores (2.16 +/− 1.61 vs 1.48 +/− 1.40; P< 0.001) and were more likely to use analgesic medicines (76.3 vs 23.7%, P= 0.002) than women with mild or no trauma. By 3 months average VAS scores were low in each group and not significantly different. Perineal pain at the time of discharge was associated in univariate analysis with higher education level, ethnicity (non-Hispanic white), nulliparity, and longer length of active maternal pushing efforts. In a multivariate model only trauma group and length of active pushing predicted pain at hospital discharge. In women with minor or no trauma, only length of the active part of second stage labor had a positive relationship with pain. In women with major trauma, the length of active second stage labor had no independent effect on level of pain at discharge beyond its effect on the incidence of major trauma. Conclusions Women with spontaneous perineal trauma reported very low rates of postpartum perineal pain. Women with major trauma reported increased perineal pain compared with women who had no or minor trauma; however, by 3 months postpartum this difference was no longer present. In women with minor or no perineal trauma, a longer period of active pushing was associated with increased perineal pain. PMID:20002420

The identification of criteria to evaluate prehospital trauma care using the Delphi technique.

Current trauma system performance improvement emphasizes hospital- and patient-based outcome measures such as mortality and morbidity, with little focus upon the processes of prehospital trauma care. Little data exist to suggest which prehospital criteria should serve as potential filters. This study identifies the most important filters for auditing prehospital trauma care using a Delphi technique to achieve consensus of expert opinion. Experts in trauma care from the United States (n = 81) were asked to generate filters of potential utility in monitoring the prehospital aspect of the trauma system, and were then required to rank these questions in order of importance to identify those of greatest importance. Twenty-eight filters ranking in the highest tertile are proposed. The majority (54%) pertains to aspects of emergency medical services, which comprise 7 of the top 10 (70%) filters. Triage filters follow in priority ranking, comprising 29% of the final list. Filters concerning interfacility transfers and transportation ranked lowest. This study identifies audit filters representing the most important aspects of prehospital trauma care that merit continued evaluation and monitoring. A subsequent trial addressing the utility of these filters could potentially enhance the sensitivity of identifying deviations in prehospital care, standardize the performance improvement process, and translate into an improvement in patient care and outcome.

Recent evidences show that osthole possesses anti-inflammatory properties and protective effects following shock-like states, but the mechanism of these effects remains unknown. The p38 mitogen-activated protein kinase (p38 MAPK) pathway exerts anti-inflammatory effects in injury. The aim of this study was to investigate whether p38 MAPK plays any role in the osthole-mediated attenuation of hepatic injury after trauma-hemorrhage. Male Sprague-Dawley rats underwent trauma-hemorrhage (mean blood pressure maintained at approximately 35-40 mmHg for 90 minutes), followed by fluid resuscitation. During resuscitation, a single dose of osthole (3 mg/kg, intravenously) with and without a p38 MAPK inhibitor SB-203580 (2 mg/kg, intravenously), SB-203580 or vehicle was administered. Plasma alanine aminotransferase (ALT) with aspartate aminotransferase (AST) concentrations and various hepatic parameters were measured (n = 8 rats/group) at 24 hours after resuscitation. The results showed that trauma-hemorrhage increased hepatic myeloperoxidase activity, intercellular adhesion molecule-1 and interleukin-6 levels, and plasma ALT and AST concentrations. These parameters were significantly improved in the osthole-treated rats subjected to trauma-hemorrhage. Osthole treatment also increased hepatic phospho-p38 MAPK expression compared with vehicle-treated trauma-hemorrhaged rats. Co-administration of SB-203580 with osthole abolished the osthole-induced beneficial effects on the above parameters and hepatic injury. These results suggest that the protective effect of osthole administration on alleviation of hepatic injury after trauma-hemorrhage, which is, at least in part, through p38 MAPK-dependent pathway.

The purpose of a scaling system for specific injuries is to provide a common language to facilitate the clinical decisions and the investigative basis for this decision making. This brief overview describes the evolution of the Organ Injury Scaling (OIS) system developed by the American Association for the Surgery of Trauma. The OIS system is based on the magnitude of anatomic disruption and is graded as 1 (minimal), 2 (mild), 3 (moderate), 4 (severe), 5 (massive), and 6 (lethal). To date, the American Association for the Surgery of Trauma OIS system has been developed for visceral and vascular injuries of the neck, chest, abdomen, and extremities. The fundamental objective of OIS is to provide a common language to describe specific organ injuries. The primary purpose of OIS is to facilitate clinical decision making and the necessary research endeavors to improve this process. A good example of this concept is the tumor, node, metastasis classification for solid organ malignancies: a system used worldwide to guide patient care and clinical investigation.

Early-life trauma is one of the strongest risk factors for later emotional psychopathology. Although research in adults highlights that childhood trauma predicts deficits in emotion regulation that persist decades later, it is unknown whether neural and behavioral changes that may precipitate illness are evident during formative, developmental years. This study examined whether automatic regulation of emotional conflict is perturbed in a high-risk urban sample of trauma-exposed children and adolescents. A total of 14 trauma-exposed and 16 age-, sex-, and IQ-matched comparison youth underwent functional MRI while performing an emotional conflict task that involved categorizing facial affect while ignoring an overlying emotion word. Engagement of the conflict regulation system was evaluated at neural and behavioral levels. Results showed that trauma-exposed youth failed to dampen dorsolateral prefrontal cortex activity and engage amygdala-pregenual cingulate inhibitory circuitry during the regulation of emotional conflict, and were less able to regulate emotional conflict. In addition, trauma-exposed youth showed greater conflict-related amygdala reactivity that was associated with diminished levels of trait reward sensitivity. These data point to a trauma-related deficit in automatic regulation of emotional processing, and increase in sensitivity to emotional conflict in neural systems implicated in threat detection. Aberrant amygdala response to emotional conflict was related to diminished reward sensitivity that is emerging as a critical stress-susceptibility trait that may contribute to the emergence of mental illness during adolescence. These results suggest that deficits in conflict regulation for emotional material may underlie heightened risk for psychopathology in individuals that endure early-life trauma.

Acoustic trauma is the most common cause of hearing loss and tinnitus in humans. However, the impact of acoustic trauma on system biology is not fully understood. It has been increasingly recognized that tinnitus caused by acoustic trauma is unlikely to be generated by a single pathological source, but rather a complex network of changes involving not only the auditory system but also systems related to memory, emotion and stress. One obvious and significant gap in tinnitus research is a lack of biomarkers that reflect the consequences of this interactive “tinnitus-causing” network. In this study, we made the first attempt to analyse brain metabolic changes in rats following acoustic trauma using metabolomics, as a pilot study prior to directly linking metabolic changes to tinnitus. Metabolites in 12 different brain regions collected from either sham or acoustic trauma animals were profiled using a gas chromatography mass spectrometry (GC/MS)-based metabolomics platform. After deconvolution of mass spectra and identification of the molecules, the metabolomic data were processed using multivariate statistical analysis. Principal component analysis showed that metabolic patterns varied among different brain regions; however, brain regions with similar functions had a similar metabolite composition. Acoustic trauma did not change the metabolite clusters in these regions. When analyzed within each brain region using the orthogonal projection to latent structures discriminant analysis sub-model, 17 molecules showed distinct separation between control and acoustic trauma groups in the auditory cortex, inferior colliculus, superior colliculus, vestibular nucleus complex (VNC), and cerebellum. Further metabolic pathway impact analysis and the enrichment overview with network analysis suggested the primary involvement of amino acid metabolism, including the alanine, aspartate and glutamate metabolic pathways, the arginine and proline metabolic pathways and the purine metabolic pathway. Our results provide the first metabolomics evidence that acoustic trauma can induce changes in multiple metabolic pathways. This pilot study also suggests that the metabolomic approach has the potential to identify acoustic trauma-specific metabolic shifts in future studies where metabolic changes are correlated with the animal's tinnitus status.

Key steps in developing a cognitive vaccine against traumatic flashbacks: visuospatial Tetris versus verbal Pub Quiz.

Flashbacks (intrusive memories of a traumatic event) are the hallmark feature of Post Traumatic Stress Disorder, however preventative interventions are lacking. Tetris may offer a 'cognitive vaccine' [1] against flashback development after trauma exposure. We previously reported that playing the computer game Tetris soon after viewing traumatic material reduced flashbacks compared to no-task [1]. However, two criticisms need to be addressed for clinical translation: (1) Would all games have this effect via distraction/enjoyment, or might some games even be harmful? (2) Would effects be found if administered several hours post-trauma? Accordingly, we tested Tetris versus an alternative computer game--Pub Quiz--which we hypothesized not to be helpful (Experiments 1 and 2), and extended the intervention interval to 4 hours (Experiment 2). The trauma film paradigm was used as an experimental analog for flashback development in healthy volunteers. In both experiments, participants viewed traumatic film footage of death and injury before completing one of the following: (1) no-task control condition (2) Tetris or (3) Pub Quiz. Flashbacks were monitored for 1 week. Experiment 1: 30 min after the traumatic film, playing Tetris led to a significant reduction in flashbacks compared to no-task control, whereas Pub Quiz led to a significant increase in flashbacks. Experiment 2: 4 hours post-film, playing Tetris led to a significant reduction in flashbacks compared to no-task control, whereas Pub Quiz did not. First, computer games can have differential effects post-trauma, as predicted by a cognitive science formulation of trauma memory. In both Experiments, playing Tetris post-trauma film reduced flashbacks. Pub Quiz did not have this effect, even increasing flashbacks in Experiment 1. Thus not all computer games are beneficial or merely distracting post-trauma - some may be harmful. Second, the beneficial effects of Tetris are retained at 4 hours post-trauma. Clinically, this delivers a feasible time-window to administer a post-trauma "cognitive vaccine".

Dropout among patients in qualified alcohol detoxification treatment: the effect of treatment motivation is moderated by Trauma Load

PubMed Central

2013-01-01

Background Motivation to change has been proposed as a prerequisite for behavioral change, although empirical results are contradictory. Traumatic experiences are frequently found amongst patients in alcohol treatment, but this has not been systematically studied in terms of effects on treatment outcomes. This study aimed to clarify whether individual Trauma Load explains some of the inconsistencies between motivation to change and behavioral change. Methods Over the course of two months in 2009, 55 patients admitted to an alcohol detoxification unit of a psychiatric hospital were enrolled in this study. At treatment entry, we assessed lifetime Trauma Load and motivation to change. Mode of discharge was taken from patient files following therapy. We tested whether Trauma Load moderates the effect of motivation to change on dropout from alcohol detoxification using multivariate methods. Results 55.4% dropped out of detoxification treatment, while 44.6% completed the treatment. Age, gender and days in treatment did not differ between completers and dropouts. Patients who dropped out reported more traumatic event types on average than completers. Treatment completers had higher scores in the URICA subscale Maintenance. Multivariate methods confirmed the moderator effect of Trauma Load: among participants with high Trauma Load, treatment completion was related to higher Maintenance scores at treatment entry; this was not true among patients with low Trauma Load. Conclusions We found evidence that the effect of motivation to change on detoxification treatment completion is moderated by Trauma Load: among patients with low Trauma Load, motivation to change is not relevant for treatment completion; among highly burdened patients, however, who a priori have a greater risk of dropping out, a high motivation to change might make the difference. This finding justifies targeted and specific interventions for highly burdened alcohol patients to increase their motivation to change. PMID:23514277

The practice of facial trauma surgery would benefit from a useful quantitative scale that measures the extent of injury. To develop a facial trauma scale that incorporates only reducible fractures and is able to be reliably communicated to health care professionals. A cadaveric tissue study was conducted from October 1 to 3, 2014. Ten cadaveric heads were subjected to various degrees of facial trauma by dropping a fixed mass onto each head. The heads were then imaged with fine-cut computed tomography. A Bony Facial Trauma Scale (BFTS) for grading facial trauma was developed based only on clinically relevant (reducible) fractures. The traumatized cadaveric heads were then scored using this scale as well as 3 existing scoring systems. Regression analysis was used to determine correlation between degree of incursion of the fixed mass on the cadaveric heads and trauma severity as rated by the scoring systems. Statistical analysis was performed to determine correlation of the scores obtained using the BFTS with those of the 3 existing scoring systems. Scores obtained using the BFTS were not correlated with dentition (95% CI, -0.087 to 1.053; P = .08; measured as absolute number of teeth) or age of the cadaveric donor (95% CI, -0.068 to 0.944; P = .08). Facial trauma scores. Among all 10 cadaveric specimens (9 male donors and 1 female donor; age range, 41-87 years; mean age, 57.2 years), the facial trauma scores obtained using the BFTS correlated with depth of penetration of the mass into the face (odds ratio, 4.071; 95% CI, 1.676-6.448) P = .007) when controlling for presence of dentition and age. The BFTS scores also correlated with scores obtained using 3 existing facial trauma models (Facial Fracture Severity Scale, rs = 0.920; Craniofacial Disruption Score, rs = 0.945; and ZS Score, rs = 0.902; P < .001 for all 3 models). In addition, the BFTS was found to have excellent interrater reliability (0.908; P = .001), which was similar to the interrater reliability of the other 3 tested trauma scales. Scores obtained using the BFTS were not correlated with dentition (odds ratio, .482; 95% CI, -0.087 to 1.053; P = .08; measured as absolute number of teeth) or age of the cadaveric donor (odds ratio, .436; 95% CI, -0.068 to 0.944; P = .08). Facial trauma severity as measured by the BFTS correlated with depth of penetration of the fixed mass into the face. In this study, the BFTS was clinically relevant, had high fidelity in communicating the fractures sustained in facial trauma, and correlated well with previously validated models. NA.

Performance improvement processes are the core of a pediatric trauma program. The ability to identify, resolve, and trend specific indicators related to patient care and to show effective loop closure can be especially challenging. Using the hospital's overall quality process as a template, the trauma program built its own electronic dashboard. Our maturing trauma PI program now guides the overall trauma care. All departments own at least one performance indicator and must provide action plans for improvement. Utilization of an electronic dashboard for trauma performance improvement has provided a highly visible scorecard, which highlights successes and tracks areas needing improvement.

Effective assessment and resuscitation of trauma patients requires an organised, multidisciplinary team. Literature evaluating leadership roles of nurses in trauma resuscitation and their effect on team performance is scarce. To assess the effect of allocating the most senior nurse as team leader of trauma patient assessment and resuscitation on communication, documentation and perceptions of leadership within an Australian emergency department. The study design was a pre-post-test survey of emergency nursing staff (working at resuscitation room level) perceptions of leadership, communication, and documentation before and after the implementation of a nurse leader role. Patient records were audited focussing on initial resuscitation assessment, treatment, and nursing clinical entry. Descriptive statistical analyses were performed. Communication trended towards improvement. All (100%) respondents post-test stated they had a good to excellent understanding of their role, compared to 93.2% pre-study. A decrease (58.1-12.5%) in 'intimidating personality' as a negative aspect of communication. Nursing leadership had a 6.7% increase in the proportion of those who reported nursing leadership to be good to excellent. Accuracy of clinical documentation improved (P = 0.025). Trauma nurse team leaders improve some aspects of communication and leadership. Development of trauma nurse leaders should be encouraged within trauma team training programmes.

Posttraumatic Stress Disorder as a Mediator Between Trauma Exposure and Comorbid Mental Health Conditions in North Korean Refugee Youth Resettled in South Korea.

PubMed

Kim, Yeunhee J

2016-02-01

A structural equation model was used to investigate the relationship between trauma exposure and comorbid mental health problems and the mediation effect of posttraumatic stress disorder (PTSD) between trauma and mental health variables. The research model is based on the stress-vulnerability conceptual framework in which PTSD as a comorbid disorder mediates the relationship between trauma exposure and mental health problems. A self-administered survey was administered to 144 North Korean refugee youth residing in South Korea. Trauma exposure, both interpersonal and noninterpersonal, had no direct relationship with comorbid mental health problems. However, interpersonal trauma contributed to comorbid mental health problems through PTSD, demonstrating the mediation effect of PTSD and supporting the stress-vulnerability hypothesis of the current research model. Clinical implications of the study and future direction for research are discussed. © The Author(s) 2014.

Critically injured patients are a very heterogeneous group, medically and economically. Their treatment is a major challenge for both the medical care and the appropriate financial reimbursement. Systematic underfunding can have a significant impact on the quality of patient care. In 2009 the German Trauma Society and the DRG-Research Group of the University Hospital Muenster initialised a DRG evaluation project to analyse the validity of case allocation of critically injured patients within the German DRG system versions 2008 and 2011 with additional consideration of clinical data from the trauma registry of the German Trauma Society. Severe deficits within the G-DRG structure were identified and specific solutions were designed and realised. A retrospective analysis was undertaken of standardised G-DRG data (§ 21 KHEntgG) including case-related cost data from 3 362 critically injured patients in the periods 2007 and 2008 from 10 university hospitals and 7 large municipal hospitals. For 1 241 cases of the sample, complementary detailed information was available from the trauma registry of the German Trauma Society to monitor the case allocation of critically injured patients within the G-DRG system. Analyses of coding and grouping, performance of case allocation, and the homogeneity of costs in the G-DRG versions 2008 and 2011 were done. The following situations were found: (i) systematic underfunding of trauma patients in the G-DRG-Version 2008, especially trauma patients with acute paraplegia; (ii) participation in the official G-DRG development for 2011 with 13 proposals which were largely realised; (ii) the majority of cases with cost-covering in the G-DRG version 2011; (iv) significant improvements in the quality of statistical criteria; (v) overfunded trauma patients with high intensive care costs; (vi) underfunding for clinically relevant critically injured patients not identified in the G-DRG system. The quality of the G-DRG system is measured by the ability to obtain adequate case allocations for highly complex and heterogeneous cases. Specific modifications of the G-DRG structures could increase the appropriateness of case allocation of critically injured patients. Additional consideration of the ISS clinical data must be further evaluated. Data-based analysis is an essential prerequisite for a constructive development of the G-DRG system and a necessary tool for the active participation of medical societies in this process. © Georg Thieme Verlag KG Stuttgart · New York.

The role of trauma documentation has grown continuously since the 1970s. Prevention and management of injuries were adapted according to the results of many analyses. Since 1993 there have been two different trauma databases in Germany: the German trauma registry (TR) and the database of the Accident Research Unit (UFO). Modern computer applications improved the data processing. Our study analysed the pros and cons of each system and compared them with those of our European neighbours. We compared the TR and the UFO databases with respect to aims and goals, advantages and disadvantages, and current status. Results were reported as means +/- standard errors of the mean. The level of significance was set at P<0.05. There were differences between the two databases concerning number and types of items, aims and goals, and demographics. The TR documents care for severely injured patients and the clinical course of different types of accidents. The UFO describes traffic accidents, accident conditions, and interrelations. The German and British systems are similar, and the French system shows interesting differences. The German trauma documentation systems focus on different points. Therefore both can be used for substantiated analyses of different hypotheses. Certain intersections of both databases may help to answer very special questions in the future.

Trauma-Informed Social Policy: A Conceptual Framework for Policy Analysis and Advocacy

PubMed Central

2016-01-01

Trauma-informed care is a service provision model used across a range of practice settings. Drawing on an extensive body of research on trauma (broadly defined as experiences that produce enduring emotional pain and distress) and health outcomes, we have argued that the principles of trauma-informed care can be extended to social policy. Citing a variety of health-related policy examples, we have described how policy can better reflect 6 core principles of trauma-informed care: safety, trustworthiness and transparency, collaboration, empowerment, choice, and intersectionality. This framework conveys a politicized understanding of trauma, reflecting the reality that trauma and its effects are not equally distributed, and offers a pathway for public health professionals to disrupt trauma-driven health disparities through policy action.

Prior research indicates an association between exposure to trauma (e.g., being victimized) and perpetration of crime, especially in the context of chronic victimization. This study examines the relationship between trauma exposure, posttraumatic stress disorder (PTSD), and history of arrest and incarceration among a representative sample of black Americans from the National Survey of American Life (N = 5,189). One-third had a history of arrest, and 18 percent had a history of incarceration. Frequency of trauma exposure was associated with involvement with the criminal justice system. Relative to never experiencing trauma, experiencing ≥4 traumas was associated with elevated odds of arrest (odds ratio [OR] = 4.03), being jailed (OR = 5.15), and being imprisoned (OR = 4.41), all p <.01. PTSD was also associated with likelihood of incarceration among those with a history of trauma (OR = 2.18, p <.01). Both trauma exposure and trauma-associated psychopathology are associated with increased likelihood of arrest and incarceration in adulthood among black Americans. PMID:27795871

Childhood reactions to terrorism-induced trauma: a review of the past 10 years.

PubMed

Fremont, Wanda P

2004-04-01

To summarize the literature about the clinical presentation and treatment interventions of childhood reactions to terrorism-induced trauma. The literature on children's responses to terrorist activities was reviewed. Over the past 10 years, more research has emerged on the subject of terrorism in children. Many of the effects of terrorism-induced trauma are similar to the effects of natural and man-made trauma. Children's responses include acute stress disorder, posttraumatic stress disorder, anxiety, depression, regressive behaviors, separation problems, sleep difficulties, and behavioral problems. However, several aspects of terrorist attacks result in unique stressors and reactions and pose specific challenges for treatment. The unpredictable, indefinite threat of terrorist events, the profound effect on adults and communities, and the effect of extensive terrorist-related media coverage exacerbates underlying anxieties and contributes to a continuous state of stress and anxiety. Intervention strategies include early community-based interventions, screening of children at risk, triage and referral, and trauma-loss-focused treatment programs. Advances have been made in the research of childhood reactions to terrorism-induced trauma. Further research is needed to identify children at risk and to determine the long-term impact on children's development. Although the preliminary results of interventions developed to help children are promising, outcome data have not been examined, and further research is needed to evaluate their effectiveness.

Blunt chest trauma is second leading cause of death among trauma patients. Early identification and aggressive management of blunt thoracic trauma is essential to reduce the significant rates of morbidity and mortality. Thoracic trauma severity score (TTS) is a better predictor of chest trauma related complications. The objective of the study was to compare outcomes between low-and high thoracic trauma severity score in blunt trauma chest patients. A cross sectional descriptive study was carried out in public and private sector hospitals of Rawalpindi, Pakistan from 2008 to 2012 and 264 patients with blunt trauma chest who reported to emergency department of the hospitals, within 48 hrs of trauma were recruited. All patients were subjected to detailed history and respiratory system examination to ascertain fracture ribs, flail segment and hemopneumothorax. Written and informed consent was taken from each patient. Permission was taken from ethical committee of the hospital. The patients with blunt chest trauma had an array of associated injuries; however there were 70.8% of patients in low TTS group and 29.2% in high TTS group. Outcome was assessed as post trauma course of the patient. Outcome in low and high TTS group was compared using Chi square test which shows a significant relationship (p=0.000) between outcome and TTS, i.e., outcome worsened with increase in TTS. It is concluded that there is a significant relationship between outcome and thoracic trauma severity. Outcome of the patient worsened with increase in thoracic trauma severity score.

Continuing Care and Trauma in Women Offenders’ Substance Use, Psychiatric Status, and Self-Efficacy Outcomes

Using secondary data analysis of 3 separate trauma-informed treatment programs for women offenders, we examine outcomes between those who received both prison and community-based substance abuse treatment (i.e., continuing care; n = 85) and those who received either prison or community aftercare treatment (n = 108). We further account for differences in trauma exposure to examine whether continuing care moderates this effect on substance use, psychiatric severity, and self-efficacy outcomes at follow-up. The main effect models of continuing care showed a significant association with high psychiatric status and did not yield significant associations with substance use or self-efficacy. However, the interaction between trauma history and continuing care showed significant effects on all 3 outcomes. Findings support the importance of a continuing care treatment model for women offenders exposed to multiple forms of traumatic events, and provide evidence of the effectiveness of integrating trauma-informed treatment into women’s substance abuse treatment.

2016-09-01

Providing adequate culture-sensitive care for a large number of refugees with trauma-related disorders constitutes a major challenge. In this context, peer support and trauma-informed peer counselling can be regarded as a valuable means to complement the psychosocial care systems. In recent years, peer support and peer education have been successfully implemented e. g. in health care education, in psychiatric care, and in the treatment of traumatized individuals. Only little research data is available for traumatized refugees. However, results are encouraging. A program is presented which integrates trauma-informed peer educators (TIP) with migration background in the care of traumatized refugees. Peers' responsibility includes emotional support and understanding the refugees' needs, sensitizing for trauma-related disorders, providing psychoeducation, and teaching trauma-specific stabilization techniques under supervision of professional psychotherapists. © Georg Thieme Verlag KG Stuttgart · New York.

OBJECTIVES This study evaluated the effect of childhood trauma exposure and the role of resilience on both depressive symptoms and suicidal ideation. METHODS 1488 military personnel and veterans, who served after September 2001, were evaluated for depressive, suicidal, and PTSD symptoms, combat exposure, childhood trauma exposure, and resiliency. Participants were enrolled as part of an ongoing multicenter study. Outcome measures were depressive symptoms and suicidal ideation. RESULTS After controlling for the effects of combat exposure and PTSD, results revealed that childhood trauma exposures were significantly associated with depressive symptoms and suicidal ideation. In addition, resilience was negatively associated with depressive symptoms and suicidal ideation, suggesting a potential protective effect. CONCLUSION These findings suggest that evaluation of childhood trauma is important in the clinical assessment and treatment of depressive symptoms and suicidal ideation among military personnel and veterans.

Background Short-term changes in pre-operative nutrition can have profound effects on surgery related outcomes such as ischemia reperfusions injury in pre-clinical models. Dietary interventions that lend protection against stress in animal models (e.g. fasting, dietary restriction [DR]) impact adipose tissue quality/quantity. Adipose tissue holds high surgical relevance due to its anatomic location and high tissue volume, and it is ubiquitously traumatized during surgery. Yet the response of adipose tissue to trauma under clinically relevant circumstances including dietary status remains poorly defined. We hypothesized that pre-operative diet alters the adipose tissue response to surgical trauma. Methods A novel mouse model of adipose tissue surgical trauma was employed. Dietary conditions (diet induced obesity [DIO], pre-operative DR) were modulated prior to application of surgical adipose tissue trauma in the context of clinically common scenarios (different ages, simulated bacterial wound contamination). Local/distant adipose tissue phenotypic responses were measured as represented by gene expression of inflammatory, tissue remodeling/growth, and metabolic markers. Results Surgical trauma had a profound effect on adipose tissue phenotype at the site of trauma. Milder but significant distal effects on non-traumatized adipose tissue were also observed. DIO exacerbated the inflammatory aspects of this response, and pre-operative DR tended to reverse these changes. Age and LPS-simulated bacterial contamination also impacted the adipose tissue response to trauma, with young adult animals and LPS treatment exacerbating the proinflammatory response. Conclusions Surgical trauma dramatically impacts both local and distal adipose tissue biology. Short-term pre-operative DR may offer a strategy to attenuate this response. PMID:23274098

Many children in the child welfare system (CWS) have histories of recurrent interpersonal trauma perpetrated by caregivers early in life often referred to as complex trauma. Children in the CWS also experience a diverse range of reactions across multiple areas of functioning that are associated with such exposure. Nevertheless, few CWSs routinely screen for trauma exposure and associated symptoms beyond an initial assessment of the precipitating event. This study examines trauma histories, including complex trauma exposure (physical abuse, sexual abuse, emotional abuse, neglect, domestic violence), posttraumatic stress, and behavioral and emotional problems of 2,251 youth (age 0 to 21; M = 9.5, SD = 4.3) in foster care who were referred to a National Child Traumatic Stress Network site for treatment. High prevalence rates of complex trauma exposure were observed: 70.4% of the sample reported at least two of the traumas that constitute complex trauma; 11.7% of the sample reported all 5 types. Compared to youth with other types of trauma, those with complex trauma histories had significantly higher rates of internalizing problems, posttraumatic stress, and clinical diagnoses, and differed on some demographic variables. Implications for child welfare practice and future research are discussed.

To investigate sleep's effect in the immediate aftermath of experiencing an analog trauma in the laboratory on reducing intrusive emotional memory formation. Sixty-five healthy women were exposed to an experimental laboratory trauma. They viewed a neutral and a trauma film in the laboratory and were randomly allocated to either a group that slept following film viewing or a group that remained awake. Sleep was recorded with electroencephalogram in a subgroup of participants in the sleep group. All participants recorded intrusive memories in the week following the film. The sleep group experienced fewer and less distressing intrusive trauma memories compared to the wake group. These effects were particularly evident toward the end of the week. Duration spent in stage N2 as opposed to light N1 sleep, a higher number of fast parietal sleep spindles and a lower rapid eye movement sleep density predicted intrusion frequency. Our results have clinical implications and set the ground for early-intervention sleep studies following trauma and prevention of chronic posttrauma disorders. © 2016 Associated Professional Sleep Societies, LLC.

We tested a conceptual model of the effect of war-trauma exposure in childhood on psychological distress in young adulthood. Participants included 151 urban Kuwaiti children (51% female; M age = 10.62 years) exposed to the 1990-1991 Gulf crisis (assessed in 1993); participants also included 140 parents (81% female; M age mothers = 36.50 years; M age fathers = 41 years). In 2003, 120 participants were reassessed as young adults (50% female; M age = 21.19 years). The conceptual model was evaluated with structural equations. War-trauma exposure was associated with psychological distress in children and parents, but parents reported larger effects than children. Parents' psychological distress did not contribute to children's psychological distress. Children's psychological distress did not dissipate over time. Social support may function as a potential mediator of the effect of war-trauma exposure on psychological distress. Findings support the importance of early detection and treatment of children exposed to war trauma. Findings also implicate social support as a factor to consider in clinical interventions for children exposed to war trauma.

Computed tomography (CT) embedded in the emergency room has gained importance in the early diagnostic phase of trauma care. In 2011, we implemented a new trauma workflow concept with a sliding CT scanner system with interventional radiology features (IVR-CT) that allows CT examination and emergency therapeutic intervention without relocating the patient, which we call the Hybrid emergency room (Hybrid ER). In the Hybrid ER, all life-saving procedures, CT examination, damage control surgery, and transcatheter arterial embolisation can be performed on the same table. Although the trauma workflow realized in the Hybrid ER may improve mortality in severe trauma, the Hybrid ER can potentially affect the efficacy of other in/outpatient diagnostic workflow because one room is occupied by one severely injured patient undergoing both emergency trauma care and CT scanning for long periods. In July 2017, we implemented a new trauma workflow concept with a dual-room sliding CT scanner system with interventional radiology features (dual-room IVR-CT) to increase patient throughput. When we perform emergency surgery or interventional radiology for a severely injured or ill patient in the Hybrid ER, the sliding CT scanner moves to the adjacent CT suite, and we can perform CT scanning of another in/outpatient. We believe that dual-room IVR-CT can contribute to the improvement of both the survival of severely injured or ill patients and patient throughput.

Unique neurobiology during the sensitive period for attachment produces distinctive infant trauma processing

Background Trauma has neurobehavioral effects when experienced at any stage of development, but trauma experienced in early life has unique neurobehavioral outcomes related to later life psychiatric sequelae. Recent evidence has further highlighted the context of infant trauma as a critical variable in determining its immediate and enduring consequences. Trauma experienced from an attachment figure, such as occurs in cases of caregiver child maltreatment, is particularly detrimental. Methods Using data primarily from rodent models, we review the literature on the interaction between trauma and attachment in early life, which highlights the role of the caregiver’s presence in engagement of attachment brain circuitry and suppressing threat processing by the amygdala. We then consider how trauma with and without the caregiver produces long-term changes in emotionality and behavior, and suggest that these experiences initiate distinct pathways to pathology. Results Together these data suggest that infant trauma processing and its enduring effects are impacted by both the immaturity of brain areas for processing trauma and the unique functioning of the early-life brain, which is biased toward processing information within the attachment circuitry. Conclusion An understanding of developmental differences in trauma processing as well as the critical role of the caregiver in further altering early life brain processing of trauma is important for developing age-relevant treatment and interventions. Highlights of this article Trauma experienced in early life has been linked with life-long outcomes for mental health through a mechanism that remains unclear. Trauma experienced in the presence of a caregiver has unique consequences. The infant brain is predisposed toward processing information using attachment circuitry rather than threat circuitry. Data from rodent models suggest that repeated trauma in the presence of a caregiver prematurely engages brain areas important for threat, which may play a role in deleterious outcome. PMID:27837581

Advanced Practice Nursing Committee on Process Improvement in Trauma: An Innovative Application of the Strong Model.

This article aims to summarize the successes and future implications for a nurse practitioner-driven committee on process improvement in trauma. The trauma nurse practitioner is uniquely positioned to recognize the need for clinical process improvement and enact change within the clinical setting. Application of the Strong Model of Advanced Practice proves to actively engage the trauma nurse practitioner in process improvement initiatives. Through enhancing nurse practitioner professional engagement, the committee aims to improve health care delivery to the traumatically injured patient. A retrospective review of the committee's first year reveals trauma nurse practitioner success in the domains of direct comprehensive care, support of systems, education, and leadership. The need for increased trauma nurse practitioner involvement has been identified for the domains of research and publication.

The link between childhood trauma and/or adversity and risk of psychosis is well known. Our aim was to determine the prevalence of childhood trauma and/or adversity in people who have psychotic disorders and to investigate the association between childhood trauma and/or adversity and a range of social and health measures. Participants (n = 391, 42% male) were specifically asked about any experience of childhood trauma and/or adversity. Respondents provided information about education, employment, physical health, and health service utilization. Univariate analyses revealed that childhood trauma and/or adversity was associated with poorer levels of self-reported physical health and social problems. This includes the experience of chronic pain, headaches, arthritis, asthma, and victimization/stigma in men. Participants with a childhood trauma and/or adversity history indicated higher rates of lifetime suicide attempts with women reporting more lifetime depressive symptoms. Multivariate analyses revealed differing profiles in relation to physical and psychological health variable between males and females. Males with the experience of childhood trauma and/or adversity were significantly more likely to report cardiovascular/stroke issues, migraines and anhedonia. Females with the experience of childhood trauma and/or adversity were more likely to report a lifetime history of elevated mood and to be married or in a de facto relationship. There has been very little research into the assessment and treatment of the effects of childhood trauma and/or adversity in adults with psychosis. Childhood trauma and/or adversity may contribute to higher rates of self-reported poor health in men and is associated with increased depression in women. Our findings suggest that interventions to address the effects of past trauma are urgently needed.

2013-01-01

Objective A functional promoter polymorphism in the MAOA gene has been implicated in neuropsychiatric disorders and also moderates the association between early life stress and mental disorders, which often co-occur with cardiovascular disease. No study has examined the relationship between MAOA genotype, childhood trauma and subclinical atherosclerosis. The objective of this investigation was to examine whether childhood trauma moderates the association between MAOA genotype and subclinical atherosclerosis. Methods A sample including 289 middle-aged male twin pairs was studied. Subclinical atherosclerosis was assessed by brachial flow-mediated dilation (FMD) using ultrasound. Childhood trauma, before age 18, was measured with the Early Trauma Inventory and included physical, emotional, and sexual abuse as well as general trauma. Generalized estimating equation models were used to test the main and interactive effects of the MAOA genotype and each domain of childhood trauma on FMD, adjusting for known risk factors. Results General trauma was the most prevalent childhood trauma (28.4%), followed by physical abuse (25.0%), emotional abuse (19.4%) and sexual abuse (11.6%). MAOA genotype was not associated with any domain of childhood trauma (β ≥ 0.36). There was no significant evidence for a main effect for the MAOA genotype (β = 0.02, p = 0.82) or childhood trauma (0.005 < β < 0.10, p > 0.54) on early atherosclerosis. However, a significant interaction was observed between MAOA genotype and physical (βinteraction = 0.37, p = 0.026) or emotional abuse (βinteraction = 0.43, p = 0.025) on subclinical atherosclerosis. Conclusion This study provides initial evidence that childhood trauma modulates the impact of MAOA variant on subclinical atherosclerosis, independent of traditional cardiovascular risk factors.

Due to the heterogeneity of severely injured patients (multiple trauma) it is difficult to assign them to homogeneic diagnosis-related groups (DRG). In recent years this has led to a systematic underfunding in the German reimbursement system (G-DRG) for cases of multiply injured patients. This project aimed to improve the reimbursement by modifying the case allocation algorithms of multiply injured patients within the G-DRG system. A retrospective analysis of standardized G-DRG data according to §21 of the Hospital Reimbursement Act (§ 21 KHEntgG) including case-related cost data from 3,362 critically injured patients from 2007 and 2008 from 10 university hospitals and 7 large municipal hospitals was carried out. For 1,241 cases complementary detailed information was available from the trauma registry of the German Trauma Society to monitor the case allocation of multiply injured patients within the G-DRG system. Analysis of coding and grouping, performance of case allocation and the homogeneity of costs in the G-DRG versions 2008-2012 was carried out. The results showed systematic underfunding of trauma patients in the G-DRG version 2008 but adequate cost covering in the majority of cases with the G-DRG versions 2011 and 2012. Cost coverage was foundfor multiply injured patients from the clinical viewpoint who were identified as multiple trauma by the G-DRG system. Some of the overfunded trauma patients had high intensive care costs. Also there was underfunding for multiple injured patients not identified as such in the G-DRG system. Specific modifications of the G-DRG allocation structures could increase the appropriateness of reimbursement of multiply injured patients. Data-based analysis is an essential prerequisite for a constructive development of the G-DRG system and a necessary tool for the active participation of medical specialist societies.

This study investigated whether lifetime experience of trauma is related to personality through instrumental and reactive trait processes, and whether lifetime trauma is a mechanism underlying the association between childhood conscientiousness and objectively assessed adult physical health. Participants (N = 831) were 442 women and 389 men from the Hawaii longitudinal study of personality and health. Teacher assessments of personality were obtained when the participants were in elementary school. Self-reported adult personality assessments, lifetime histories of trauma experience, and objectively assessed physiological dysregulation were obtained between ages 45-55. Women tended to report more high-betrayal trauma than men, whereas men reported more low-betrayal trauma than women. Women who were judged by their teachers to be less agreeable and less conscientious in childhood reported more lifetime trauma, suggesting instrumental trait processes. For both genders, neuroticism and openness/intellect/imagination in adulthood, but not in childhood, were associated with lifetime trauma, suggesting reactive trait processes. For both genders, trauma experience was correlated with dysregulation and with Body Mass Index (BMI). The indirect paths from childhood conscientiousness to adult dysregulation and BMI through total teen and adult trauma were significant for women, but not for men (indirect effect for women's dysregulation = -.025, p = .040, 95% confidence interval [CI] = -.048, -.001; indirect effect for women's BMI = -.037, p = .009, 95% CI = -.067, -.008). Teen and adult trauma experience appears to be a hitherto unidentified mechanism in women underlying the association between conscientiousness and health.

Psychoanalytic perspectives on early trauma: interviews with thirty analysts who treated an adult victim of a circumscribed trauma in early childhood.

Gaensbauer, Theodore J; Jordan, Leslie

2009-08-01

Information on the long-term effects of early trauma and how such effects are manifested in treatment was obtained through interviews with thirty analysts who had treated an adult patient with a circumscribed trauma in the first four years of life. Childhood traumas fell into four categories: medical/accidental; separation/loss; witnessing a traumatic event; and physical/sexual abuse. Traumatic carryover was recorded in terms of explicit memories, implicit memories (somatic reliving, traumatic dreams, affective memories, behavioral reenactments, and transference phenomena), and global carryover effects (generalized traumatic affective states, defensive styles, patterns of object relating, and developmental disruptions). Linkages between the early trauma and adult symptomatology could be posited in almost every case, yet the clinical data supporting such linkages was often fragmented and ambiguous. Elements of patients' traumas appeared to be dispersed along variable avenues of expression and did not appear amenable to holistic, regressive reworking in treatment. The data did not support linear models of traumatic carryover or the idea that early traumatic experiences will be directly accessible in the course of an analysis. Factors that we believe help explain why traumatic aftereffects in our sample were so heterogeneous and difficult to track over the long term are discussed.

The aim of this study was to evaluate the possible correlations between the grade of fat embolism and age, gender, severity of trauma and post-traumatic survival time. Thirty-one cases with pulmonary and/or systemic fat embolism, auotopsied at the Morgue Department of Council of Forensic Medicine were evaluated retrospectively. Twenty-eight cases (90%) died due to trauma and its complications. Nineteen cases (61%) were injured in motor vehicle-related accidents. Post-traumatic survival time varied between 0-384 hours (61.6+/-86.2 hours). Abbreviated injury scale (AIS) was 8.1+/-3.9 and injury severity score (ISS) was 26.5+/-19.7 SD. Twenty-four (77%) cases were determined as isolated pulmonary fat embolism and 7 (23%) cases as systemic fat embolism on histopathological examination. Possible correlations between the grade of fat embolism and age, gender, severity of trauma and post-traumatic survival time were evaluated statistically with using Chi-square and Spearman's correlation tests. There were no correlations between the grade of fat embolism and age, gender, the severity of trauma. Post-traumatic survival time and the severity of trauma had a very weak negative correlation without any statistical significance.

Convergent paradigms for visual neuroscience and dissociative identity disorder.

PubMed

Manning, Mark L; Manning, Rana L

2009-01-01

Although dissociative identity disorder, a condition in which multiple individuals appear to inhabit a single body, is a recognized psychiatric disorder, patients may yet encounter health professionals who declare that they simply "do not believe in multiple personalities." This article explores the proposal that resistance to the disorder represents a failure to apply an appropriate paradigm from which the disorder should be interpreted. Trauma and sociocognitive explanations of dissociative identity disorder are contrasted. The trauma hypothesis is further differentiated into paradigms in which trauma affects a defense mechanism, and one in which trauma serves to inhibit the normal integration sequence of parallel processes of the self in childhood. This latter paradigm is shown to be broadly consistent with current models of cortical processing in another system, the cortical visual system.

Trauma and related mental health disorders are common among incarcerated women, but empirically sound mental health interventions are lacking in prisons. Implementing such interventions is fraught with legal and logistical barriers. These barriers can be particularly detrimental for trauma-specific interventions given the unique needs of trauma survivors, yet there is little documentation of these issues or how to address them. This study describes a pilot study of an 8-week, strengths-based, trauma-focused intervention for 26 incarcerated women. Women reported considerable mental health problems and trauma. The study highlights the importance of adapting stringent research methodologies for prison-based trauma interventions. For instance, women with trauma were reluctant to participate in an intervention advertised as trauma-based. Moreover, a randomized wait list control design was unfeasible because women wanted the support of their friends when discussing trauma and could not control their schedules 9 weeks in advance. Ultimately, this work may inform future efforts to implement effective trauma-based interventions behind prison walls. © The Author(s) 2013.

Seven Deadly Sins in Trauma Outcomes Research: An Epidemiologic Post-Mortem for Major Causes of Bias

2013-01-01

Background Because randomized clinical trials (RCTs) in trauma outcomes research are expensive and complex, they have rarely been the basis for the clinical care of trauma patients. Most published findings are derived from retrospective and occasionally prospective observational studies that may be particularly susceptible to bias. The sources of bias include some common to other clinical domains, such as heterogeneous patient populations with competing and interdependent short- and long-term outcomes. Other sources of bias are unique to trauma, such as rapidly changing multi-system responses to injury that necessitate highly dynamic treatment regimes like blood product transfusion. The standard research design and analysis strategies applied in published observational studies are often inadequate to address these biases. Methods Drawing on recent experience in the design, data collection, monitoring and analysis of the 10-site observational PROMMTT study, seven common and sometimes overlapping biases are described through examples and resolution strategies. Results Sources of bias in trauma research include ignoring 1) variation in patients’ indications for treatment (indication bias), 2) the dependency of intervention delivery on patient survival (survival bias), 3) time-varying treatment, 4) time-dependent confounding, 5) non-uniform intervention effects over time, 6) non-random missing data mechanisms, and 7) imperfectly defined variables. This list is not exhaustive. Conclusion The mitigation strategies to overcome these threats to validity require epidemiologic and statistical vigilance. Minimizing the highlighted types of bias in trauma research will facilitate clinical translation of more accurate and reproducible findings and improve the evidence-base that clinicians apply in their care of injured patients.

Vascular trauma and prostacyclin release.

Jeremy, J Y; Mikhailidis, D P; Dandona, P

1984-10-01

The effect of trauma on prostacyclin (PGI2) secretion by rat aorta was examined. Whereas cutting and puncturing markedly increased PGI2 secretion, sonication and stretch had no effect. Cutting and puncturing were also effective in stimulating further endogenous secretion of PGI2 from 'exhausted' aortic segments in whom PGI2 production had dwindled to a negligible rate. These experiments show that trauma is an important stimulator of PGI2 secretion, the exhaustion of PGI2 secretion by vascular segments is not due to the depletion of substrate (arachidonic acid) and that an unusually traumatic venepuncture may invalidate the subsequent assays of PGI2 and its stable metabolite, 6-oxo-PGF1 alpha, in plasma. The close relationship of vascular trauma to PGI2 release also suggests a possible cytoprotective effect of this prostanoid on vascular endothelium.

Admission platelet (PLT) counts are known to be associated with all-cause mortality for seriously injured patients admitted to a trauma center. The course of subsequent PLT counts, their implications, and the effects of PLT therapy are less well known. Trauma center patients who were directly admitted from the scene of injury, received 1 or more units of uncrossmatched red blood cells in the first hour of care, survived for at least 15 minutes, and had a PLT count measured in the first hour were analyzed for the association of their admission and subsequent PLT counts in the first 24 hours with injury severity and hemorrhagic and central nervous system (CNS) causes of in-hospital mortality. Over an 8.25-year period, 1292 of 45,849 direct trauma admissions met entry criteria. Admission PLT counts averaged 228×10(9) ±90×10(9) /L and decreased by 104×10(9) /L by the second hour and 1×10(9) /L each hour thereafter. The admission count was not related to time to admission. Each 1-point increase in the injury severity score was associated with a 1×10(9) /L decrease in the PLT count at all times in the first 24 hours of care. Admission PLT counts were strongly associated with hemorrhagic and CNS injury mortality and subsequent PLT counts. Effects of PLT therapy could not be ascertained. Admission PLT counts in critically injured trauma patients are usually normal, decreasing after admission. Low PLT counts at admission and during the course of trauma care are strongly associated with mortality. © 2012 American Association of Blood Banks.

Betrayal trauma: relationship to physical health, psychological distress, and a written disclosure intervention.

Freyd, Jennifer J; Klest, Bridget; Allard, Carolyn B

2005-01-01

In the current study we sought, first, to distinguish associations with health arising from types of trauma as indicated by betrayal trauma theory (Freyd, 1996, 2001), and, second, to investigate the impact of disclosing a trauma history in survey form and/or writing essays about betrayal traumas. We recruited 99 community adults reporting at least 12 months of chronic medical illness or pain, 80 of whom completed all four sessions of this six-month longitudinal intervention study. Participants were randomly assigned to write about betrayal traumas or neutral events, and they were randomly assigned to complete an extensive trauma survey or a long personality inventory, producing four groups of participants. All 99 participants were assessed at their initial visit for trauma history using the Brief Betrayal Trauma Survey (BBTS) and physical and mental symptoms. The BBTS assesses exposure to both traumas high in betrayal (such as abuse by a close other) and traumas low in betrayal but high in life-threat (such as an automobile accident). Exposure to traumas with high betrayal was significantly correlated with number of physical illness, anxiety, dissociation, and depression symptoms. Amount of exposure to other types of traumas (low betrayal traumas) did not predict symptoms over and above exposure to betrayal trauma. While neither the survey manipulation nor the writing intervention led to main effects on change in symptoms over time, there were interactions between betrayal trauma history and condition such that participants with many betrayal traumas fared better in the control conditions while participants with fewer betrayal traumas had better outcomes if they were placed in the trauma writing and/or survey conditions. We discuss ongoing and future research aimed at evaluating the role of increased structure in writing assignments as beneficial for those with severe histories of betrayal trauma.

The prevalence of PTSD differs by gender. Pre-existing psychiatric disorders and different traumas experienced by men and women may explain this. The aims of this study were to assess (1) incidence and prevalence of exposure to traumatic events and PTSD, (2) the effect of pre-existing psychiatric disorders prior to trauma on the risk for PTSD, and (3) the effect the characteristics of trauma have on the risk for PTSD. All stratified by gender. CIDI was used to obtain diagnoses at the interview stage and retrospectively for the general population N = 1634. The incidence for trauma was 466 and 641 per 100,000 PYs for women and men, respectively. The incidence of PTSD was 88 and 31 per 100,000 PYs. Twelve month and lifetime prevalence of PTSD was 1.7 and 4.3 %, respectively, for women, and 1.0 and 1.4 %, respectively, for men. Pre-existing psychiatric disorders were risk factors for PTSD, but only in women. Premeditated traumas were more harmful. Gender differences were observed regarding traumatic exposure and in the nature of traumas experienced and incidences of PTSD. Men experienced more traumas and less PTSD. Pre-existing psychiatric disorders were found to be risk factors for subsequent PTSD in women. However, while trauma happens to most, it only rarely leads to PTSD, and the most harmful traumas were premeditated ones. Primary prevention of PTSD is thus feasible, although secondary preventive efforts should be gender-specific.

The purpose of this study was to evaluate the effectiveness of outpatient substance abuse treatment for youth with high traumatic stress compared to youth without high traumatic stress in substance abuse treatment centers across the United States. The data for this study were gathered using a longitudinal survey design with purposive sampling from nine drug treatment delivery systems across the United States participating in the cooperative grant Strengthening Communities for Youth (SCY) awarded by SAMHSA's Center for Substance Abuse Treatment (CSAT) between September 2002 and June 2006. Follow-up assessments were conducted with the youth at three,six, and 12 months following intake. Traumatized youth responded to outpatient treatment in a similar pattern when compared to nontraumatized youth, although the traumatized youth had consistently higher scores on substance use frequency and substance problems scales than nontraumatized youth throughout the study. Current empirically validated treatments for adolescent substance abuse do not prepare the practitioner for trauma-informed practice or specifically address trauma-informed recovery. Based on our results, we advocate for the development and integration of trauma-informed practice within substance abuse treatment for adolescents to help them recover from trauma and substance abuse issues.

Trauma represents a significant and increasing challenge to health care systems all over the world. This study aimed to evaluate the trauma care capabilities of Botswana, a middle-income African country, by applying the World Health Organization's Guidelines for Essential Trauma Care. All 27 government (16 primary, 9 district, 2 referral) hospitals were surveyed. A questionnaire and checklist, based on "Guidelines for Essential Trauma Care" and locally adapted, were developed as situation analysis tools. The questionnaire assessed local trauma organization, capacity, and the presence of quality improvement activity. The checklist assessed physical availability of equipment and timely availability of trauma-related skills. Information was collected by interviews with hospital administrators, key personnel within trauma care, and through on-site physical inspection. Hospitals in Botswana are reasonably well supplied with human and physical resources for trauma care, although deficiencies were noted. At the primary and district levels, both capacity and equipment for airway/breathing management and vascular access was limited. Trauma administrative functions were largely absent at all levels. No hospital in Botswana had any plans for trauma education, separate from or incorporated into other improvement activities. Team organization was nonexistent, and training activities in the emergency room were limited. This study draws a picture of trauma care capabilities of an entire African country. Despite good organizational structures, Botswana has room for substantial improvement. Administrative functions, training, and human and physical resources could be improved. By applying the guidelines, this study creates an objective foundation for improved trauma care in Botswana.

Importance Collection and analysis of up-to-date and accurate injury surveillance data are a key step in the maturation of trauma systems. Trauma registries have proven to be difficult to establish in low- and middle-income countries owing to the burden of trauma volume, cost, and complexity. Objective To determine whether an electronic trauma health record (eTHR) used by physicians can serve as simultaneous clinical documentation and data acquisition tools. Design, Setting, and Participants This 2-part quality improvement study included (1) preimplementation and postimplementation eTHR study with assessments of satisfaction by 41 trauma physicians, time to completion, and quality of data collected comparing paper and electronic charting; and (2) prospective ecologic study describing the burden of trauma seen at a Level I trauma center, using real-time data collected by the eTHR on consecutive patients during a 12-month study period. The study was conducted from October 1, 2010, to September 30, 2011, at Groote Schuur Hospital, Cape Town, South Africa. Data analysis was performed from October 15, 2011, to January 15, 2013. Main Outcomes and Measures The primary outcome of part 1 was data field competition rates of pertinent trauma registry items obtained through electronic or paper documentation. The main measures of part 2 were to identify risk factors to trauma in Cape Town and quality indicators recommended for trauma system evaluation at Groote Schuur Hospital. Results The 41 physicians included in the study found the electronic patient documentation to be more efficient and preferable. A total of 11 612 trauma presentations were accurately documented and promptly analyzed. Fields relevant to injury surveillance in the eTHR (n = 11 612) had statistically significant higher completion rates compared with paper records (n = 9236) (for all comparisons, P < .001). The eTHR successfully captured quality indicators recommended for trauma system evaluation which were previously challenging to collect in a timely and accurate manner. Of the 11 612 patient admissions over the study period, injury location was captured 11 075 times (95.4%), injury mechanism 11 135 times (95.9%), systolic blood pressure 11 106 times (95.6%), and Glasgow Coma Scale 11 140 times (95.9%). These fields were successfully captured with statistically higher rates than previous paper documentation. Epidemiologic analysis confirmed a heavy burden of violence-related injury (51.8% of all injuries) and motor vehicle crash injuries (14.3% of all injuries). Mapping analysis demonstrated clusters of injuries originating mainly from vulnerable and low-income neighborhoods and their respective referring trauma facilities, Mitchell’s Plain Hospital (734 [10.1%]), Guguletu Community Health Center (654 [9.0%]), and New Somerset Hospital (400 [5.5%]). Conclusions and Relevance Accurate capture and simultaneous analysis of trauma data in low-resource trauma settings are feasible through the integration of surveillance into clinical workflow and the timely analysis of electronic data.

Acinetobacter baumannii is an important nosocomial pathogen in civilian intensive care units. Recently the incidence has increased in wounded military personnel. Morphine is documented in numerous animal studies to be immunosuppressive and to sensitize to infection. The hypotheses were tested that morphine, administered for analgesia in the battlefield, predisposes to Acinetobacter infection, and that the opioid may have an additive or synergistic effect with trauma. To test these hypotheses, an intraperitoneal infection model was established in mice using several Acinetobacter strains. Morphine administered for 48 hr by implantation of a slow-release morphine pellet increased mortality compared to animals receiving a placebo pellet, an effect that was blocked by the mu-opioid receptor antagonist, naltrexone. Acinetobacter burdens in the blood, spleens, livers, and lungs of morphine-treated mice, were significantly higher than those in placebo-treated animals, confirming that mortality was due to potentiated growth of the bacteria. There were also elevated levels of pro-inflammatory cytokines in morphine-treated versus placebo-treated mice. Morphine caused a reduction in the total number of cells in the peritoneal cavity, a decrease in the percentage and total numbers of neutrophils, and a decrease in the total number of macrophages. Morphine treatment also suppressed levels of the neutrophil-inducing molecules, IL-17A and KC/CXCL1. However, IL-17A−/− mice given morphine were not sensitized to Acintobacter infection to a greater degree than similarly treated wild-type mice. Trauma alone did not sensitize to Acinetobacter infection, and there was no additive effect between morphine and trauma. These results support the hypothesis that morphine potentiates Acinetobacter infection. PMID:21826405

Previous refugee research has been unable to link pre-displacement trauma with unemployment in the host country. The current study assessed the role of pre-displacement trauma, post-displacement trauma, and the interaction of both trauma types to prospectively examine unemployment in a random sample of newly-arrived Iraqi refugees. Participants (N=286) were interviewed three times over the first two years post-arrival. Refugees were assessed for pre-displacement trauma exposure, post-displacement trauma exposure, a history of unemployment in the country of origin and host country, and symptoms of posttraumatic stress disorder (PTSD) and depression. Analyses found that neither pre-displacement nor post-displacement trauma independently predicted unemployment 2 years post-arrival; however, the interaction of pre and post-displacement trauma predicted 2-year unemployment. Refugees with high levels of both pre and post-displacement trauma had a 91% predicted probability of unemployment, whereas those with low levels of both traumas had a 20% predicted probability. This interaction remained significant after controlling for sociodemographic variables and mental health upon arrival to the U.S. Resettlement agencies and community organizations should consider the interactive effect of encountering additional trauma after escaping the hardships of the refugee's country of origin.

2010-12-01

To provide a systematic review on ocular firework trauma with emphasis on incidence and patient demographics, the extent of ocular trauma and visual function loss, and firework regulation effects on injury rates. A literature search was performed using predetermined inclusion and exclusion criteria. Demographic characteristics of ocular firework casualties were obtained and incidence rates of sustained trauma and vision loss calculated. Twenty-six relevant articles were suitable for calculation of trauma incidence and patient demographics, of which 17 articles could be used for calculating trauma severity and vision loss. Victims were male (77%), young (82%) and often bystander (47%). Most of the trauma was mild and temporary. Penetrating eye trauma, globe contusions and burns accounted for 18.2%, with a 3.9% enucleation rate. Mean visual acuity was >10/20 in 56.8%, with severe vision loss (<10/200) in 16.4%. Countries using restrictive firework legislation show 87% less eye trauma (p<0.005). One in six ocular firework traumas show severe vision loss, mostly in young males. Bystanders are as frequently injured. Firework traumas are a preventable cause of severe ocular injury and blindness because countries using restrictive firework legislation have remarkable lower trauma incidence rates.

The purpose of this article was to review the empirical literature that investigated trauma and stress among older adults in the criminal justice system. Nineteen journal articles published between 1988 and 2010 were identified and extracted via research databases and included mixed age samples of adjudicated older and younger adults (n = 11) or older adult only samples (n = 8). Findings revealed past and current trauma and stress, consequences and/or correlates, and internal and external coping resources among aging offenders. The implications and future directions for gerontological social work, research, and policy with older adults in the criminal justice system are advanced.

This review highlights early efforts to translate pre-clinical and clinical findings regarding the role of neuroactive steroids in stress adaptation and PTSD into new therapeutics for PTSD. Numerous studies have demonstrated PTSD-related alterations in resting levels or the reactivity of neuroactive steroids and their targets. These studies also have demonstrated substantial variability in the dysfunction of specific neuroactive steroid systems among PTSD subpopulations. These variabilities have been related to the developmental timing of trauma, severity and type of trauma, genetic background, sex, reproductive state, lifestyle influences such as substance use and exercise, and the presence of comorbid conditions such as depression and chronic pain. Nevertheless, large naturalistic studies and a small placebo-controlled interventional study have revealed generally positive effects of glucocorticoid administration in preventing PTSD after trauma, possibly mediated by glucocorticoid receptor-mediated effects on other targets that impact PTSD risk, including other neuroactive steroid systems. In addition, clinical and preclinical studies show that administration of glucocorticoids, 17β-estradiol, and GABAergic neuroactive steroids or agents that enhance their synthesis can facilitate extinction and extinction retention, depending on dose and timing of dose in relation to these complex PTSD-relevant recovery processes. This suggests that clinical trials designed to test neuroactive steroid therapeutics in PTSD may benefit from such considerations; typical continuous dosing regimens may not be optimal. In addition, validated and clinically accessible methods for identifying specific neuroactive steroid system abnormalities at the individual level are needed to optimize both clinical trial design and precision medicine based treatment targeting.

Recent evidences show that osthole possesses anti-inflammatory properties and protective effects following shock-like states, but the mechanism of these effects remains unknown. The p38 mitogen-activated protein kinase (p38 MAPK) pathway exerts anti-inflammatory effects in injury. The aim of this study was to investigate whether p38 MAPK plays any role in the osthole-mediated attenuation of hepatic injury after trauma-hemorrhage. Male Sprague-Dawley rats underwent trauma-hemorrhage (mean blood pressure maintained at approximately 35–40 mmHg for 90 minutes), followed by fluid resuscitation. During resuscitation, a single dose of osthole (3 mg/kg, intravenously) with and without a p38 MAPK inhibitor SB-203580 (2 mg/kg, intravenously), SB-203580 or vehicle was administered. Plasma alanine aminotransferase (ALT) with aspartate aminotransferase (AST) concentrations and various hepatic parameters were measured (n = 8 rats/group) at 24 hours after resuscitation. The results showed that trauma-hemorrhage increased hepatic myeloperoxidase activity, intercellular adhesion molecule-1 and interleukin-6 levels, and plasma ALT and AST concentrations. These parameters were significantly improved in the osthole-treated rats subjected to trauma-hemorrhage. Osthole treatment also increased hepatic phospho-p38 MAPK expression compared with vehicle-treated trauma-hemorrhaged rats. Co-administration of SB-203580 with osthole abolished the osthole-induced beneficial effects on the above parameters and hepatic injury. These results suggest that the protective effect of osthole administration on alleviation of hepatic injury after trauma-hemorrhage, which is, at least in part, through p38 MAPK-dependent pathway.

The goal of this study was to integrate temporal and weather data in order to create an artificial neural network (ANN) to predict trauma volume, the number of emergent operative cases, and average daily acuity at a level 1 trauma center. Trauma admission data from TRACS and weather data from the National Oceanic and Atmospheric Administration (NOAA) was collected for all adult trauma patients from July 2013-June 2016. The ANN was constructed using temporal (time, day of week), and weather factors (daily high, active precipitation) to predict four points of daily trauma activity: number of traumas, number of penetrating traumas, average ISS, and number of immediate OR cases per day. We trained a two-layer feed-forward network with 10 sigmoid hidden neurons via the Levenberg-Marquardt backpropagation algorithm, and performed k-fold cross validation and accuracy calculations on 100 randomly generated partitions. 10,612 patients over 1,096 days were identified. The ANN accurately predicted the daily trauma distribution in terms of number of traumas, number of penetrating traumas, number of OR cases, and average daily ISS (combined training correlation coefficient r = 0.9018+/-0.002; validation r = 0.8899+/- 0.005; testing r = 0.8940+/-0.006). We were able to successfully predict trauma and emergent operative volume, and acuity using an ANN by integrating local weather and trauma admission data from a level 1 center. As an example, for June 30, 2016, it predicted 9.93 traumas (actual: 10), and a mean ISS score of 15.99 (actual: 13.12); see figure 3. This may prove useful for predicting trauma needs across the system and hospital administration when allocating limited resources. Level III STUDY TYPE: Prognostic/Epidemiological.

The purpose of a curfew is to decrease the amount of crime inflicted on minors during the late hours of the night. On June 1, 1994, a city curfew was instituted in New Orleans, requiring all persons 17 years of age or younger to be off the streets from 9 PM to 6 AM Sunday through Thursday, and from 11 PM to 6 AM on Friday and Saturday. This study evaluated the effect of the curfew on emergency medical services (EMS) transports for patients who were 17 years old or younger (pediatric). Data from all pediatric transports were included from the months before (5/94) and after (6/94) the institution of the curfew, and from the same two months one year earlier (5/93 and 6/93). A chi-square test was used to evaluate comparisons. The city EMS transports 48,000 patients per year in a one-tiered system (paramedic only) that acts as the sole provider of emergency EMS transport in the city. Approximately 10% of all transports are pediatric, and 40% of the pediatric transports are for trauma. A total of 1,642 transports were found that fit the inclusion criteria. In May 1993, there were 415 total pediatric transports; 234 were pediatric trauma. In June 1993, there were 406 total pediatric transports; 250 were pediatric trauma. In May 1994, there were 447 total pediatric runs; 243 were pediatric trauma. During the postcurfew month, June 1994, there were a significant decrease in pediatric transports to 370 (p < 0.01) and a significant decrease in pediatric trauma transport to 189 (p < 0.01). The institution of a curfew may lead to a drop in pediatric EMS runs during curfew hours. Another value of the curfew may be in the secondary effects of the curfew in preventing childhood injury during noncurfew hours.

Psychiatric and physical sequelae of childhood physical and sexual abuse and forced sexual trauma among individuals with serious mental illness.

Trauma and posttraumatic stress disorder (PTSD) frequently co-occur with serious mental illness, yet the unique mental and physical health influences of childhood physical abuse (CPA), childhood sexual abuse (CSA), and forced sexual trauma on individuals with serious mental illness remain unevaluated. The present study of 172 individuals with serious mental illness investigated the adverse effects of CPA, CSA, and forced sexual trauma on severity of PTSD and depression, and overall mental and physical health functioning. Data analysis consisted of chi-square tests, independent t tests, bivariate odds ratios, and linear regressions. Prevalence of CPA (44.8%), CSA (29.1%), and forced sexual trauma (33.1%) were elevated, and nearly one third of participants (31.4%) reported clinical PTSD. Participants exposed to CSA or forced sexual trauma evidenced bivariate ORs ranging from 4.13 to 7.02 for PTSD, 2.44 to 2.50 for major depression, and 2.14 to 2.31 for serious physical illness/disability. Sexual trauma exposure associated with heightened PTSD and depression, and reduced mental and physical health functioning, with CSA uniquely predicting PTSD, depression, and physical health difficulties. CPA less significantly affected these clinical domains. Sexual traumas have profound negative effects on mental and physical health outcomes among individuals with serious mental illness; increased screening and treatment of sexual traumas is needed.

Trauma resuscitation is a complex situation, and most organisations have multi-professional trauma teams. Non-technical skills are challenged during trauma resuscitation, and they play an important role in the prevention of critical incidents. Simulation-based training of these is recommended. Our research question was: Does simulation-based trauma team training of non-technical skills have effect on reaction, learning, behaviour or patient outcome? The authors searched PubMed, EMBASE and the Cochrane Library and found 13 studies eligible for analysis. We described and compared the educational interventions and the evaluations of effect according to the four Kirkpatrick levels: reaction, learning (knowledge, skills, attitudes), behaviour (in a clinical setting) and patient outcome. No studies were randomised, controlled and blinded, resulting in a moderate to high risk of bias. The multi-professional trauma teams had positive reactions to simulation-based training of non-technical skills. Knowledge and skills improved in all studies evaluating the effect on learning. Three studies found improvements in team performance (behaviour) in the clinical setting. One of these found difficulties in maintaining these skills. Two studies evaluated on patient outcome, of which none showed improvements in mortality, complication rate or duration of hospitalisation. A significant effect on learning was found after simulation-based training of the multi-professional trauma team in non-technical skills. Three studies demonstrated significantly increased clinical team performance. No effect on patient outcome was found. All studies had a moderate to high risk of bias. More comprehensive randomised studies are needed to evaluate the effect on patient outcome. © 2014 The Acta Anaesthesiologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

To evaluate the impact of Medicare's inpatient rehabilitation facility (IRF) prospective payment system (PPS) on use of inpatient rehabilitation for individuals with traumatic brain injury (TBI). Retrospective cohort study of patients with TBI. One hundred twenty-three level I and II trauma centers across the U.S. who contributed data to the National Trauma Data Bank. Patients (N=135,842) with TBI and an Abbreviated Injury Score of the head of 2 or greater admitted to trauma centers between 1995 and 2004. None. Discharge location: IRF, skilled nursing facility, home, and other hospitals. Compared with inpatient rehabilitation admissions before IRF PPS came into effect, demographic characteristics of admitted patients changed. Those admitted to acute care trauma centers after PPS was enacted (January 2002) were older and nonwhite. No differences were found in rates of injury between men and women. Over time, there was a significant drop in the percent of patients being discharged to inpatient rehabilitation, which varied by region, but was found across all insurance types. In a logistic regression, after controlling for patient characteristics (age, sex, race), injury characteristics (cause, severity), insurance type, and facility, the odds of being discharged to an IRF after a TBI decreased 16% after Medicare's IRF PPS system was enacted. The enactment of the Medicare PPS appears to be associated with a reduction in the chance that patients receive inpatient rehabilitation treatment after a TBI. The impact of these changes on the cost, quality of care, and patient outcome is unknown and should be addressed in future studies. Copyright © 2012 American Congress of Rehabilitation Medicine.

Evaluation of the Effects of Receiving Trauma-Informed Practices on Domestic Violence Shelter Residents.

2017-08-17

Domestic violence is a potentially traumatizing experience that has devastating psychological and physical consequences. In response, domestic violence shelter programs have focused increasing attention on helping adult and child survivors understand and heal from this trauma. What have come to be called trauma-informed practices include (a) reflecting an understanding of trauma and its many effects on health and behavior, (b) addressing both physical and psychological safety concerns, (c) using a culturally informed strengths-based approach, (d) helping to illuminate the nature and effects of abuse on survivors' everyday experience; and (e) providing opportunities for clients to regain control over their lives. Despite the proliferation of these practices, little is known about their effects on survivors. In response, the current study explored the extent to which trauma-informed practices, as experienced by shelter residents, related to changes in their levels of self-efficacy, safety-related empowerment, and depressive symptoms over the course of approximately 30 days in shelter. Fifty-seven shelter residents from 4 programs in Ohio completed surveys shortly after arriving in shelter and again before exit. Their perception of the degree to which they received trauma-informed services was associated with significant improvement in their self-efficacy and safety-related empowerment, but had no impact on depressive symptoms. Depressive symptoms decreased over time, regardless of receipt of trauma-informed practice. Implications for policy and practice are discussed.

Presence of the dissociative subtype of PTSD does not moderate the outcome of intensive trauma-focused treatment for PTSD

PubMed Central

2018-01-01

ABSTRACT Background: There is a widely-held belief in the trauma field that the presence of dissociative symptoms is associated with poor treatment response. However, previous research on the effect of dissociation in treatment outcomes pertained to specific patients and trauma populations. Objective: To test the hypothesis that the presence of the dissociative subtype of PTSD (DS) would have a detrimental effect on the outcome of an intensive trauma-focused treatment programme. Methods: PTSD symptom scores (Clinician Administered PTSD Scale [CAPS] and PTSD Symptom Scale Self-Report [PSS-SR]) were analysed using the data of 168 consecutive patients (70.6% female) who had been exposed to a wide variety of multiple traumas, including childhood sexual abuse, and of whom 98.2% were diagnosed with severe PTSD (CAPS > 65). Most of them suffered from multiple comorbidities and 38 (22.6%) met the criteria for DS. They took part in an intensive trauma-focused treatment programme for PTSD. Pre- and post-treatment differences were compared between patients with and without DS. Results: Large effect sizes were achieved for PTSD symptom reduction on CAPS and the PSS-SR, both for patients with DS and those without. Although patients with DS showed a significantly greater PTSD symptom severity at the beginning, and throughout, treatment, both groups showed equal reductions in PTSD symptoms. Of those who met the criteria for DS, 26 (68.4%) no longer fulfilled the criteria for this classification after treatment. Conclusion: The results provide no support for the notion that the presence of DS negatively impacts trauma-focused treatment outcomes. Accordingly, PTSD patients with DS should not be denied effective trauma-focused treatments. PMID:29805779

The effective treatment of airway compromise in trauma and non-trauma patients is important. Hypoxia and hypotension are predictors of negative patient outcomes and increased mortality, and may be important quality indicators of care provided by emergency medical services. Excluding cardiac arrests, critical trauma and non-trauma patients remain the two major groups to which helicopter emergency medical services (HEMS) are dispatched. Several studies describe the impact of pre-hospital hypoxia or hypotension on trauma patients, but few studies compare this in trauma and non-trauma patients. The primary aim was to describe the incidence of pre-hospital hypoxia and hypotension in the two groups receiving pre-hospital tracheal intubation (TI) by physician-staffed HEMS. Data were collected prospectively over a 12-month period, using a uniform Utstein-style airway template. Twenty-one physician-staffed HEMS in Europe and Australia participated. We compared peripheral oxygen saturation and systolic blood pressure before and after definitive airway management. Data were analysed using Cochran-Mantel-Haenszel methods and mixed-effects models. Eight hundred forty three trauma patients and 422 non-trauma patients receiving pre-hospital TI were included. Non-trauma patients had significantly lower predicted mean pre-intervention SpO 2 compared to trauma patients. Post-intervention and admission SpO 2 for the two groups were comparable. However, 3% in both groups were still hypoxic at admission. For hypotension, the differences between the groups were less prominent. However, 9% of trauma and 10% of non-trauma patients were still hypotensive at admission. There was no difference in short-term survival between trauma (97%) and non-trauma patients (95%). Decreased level of consciousness was the most frequent indication for TI, and was associated with increased survival to hospital (cOR 2.8; 95% CI: 1.4-5.4). Our results showed that non-trauma patients had a higher incidence of hypoxia before TI than trauma patients, but few were hypoxic at admission. The difference for hypotension was less prominent, but one in ten patients were still hypotensive at admission. Further investigations are needed to identify reversible causes that may be corrected to improve haemodynamics in the pre-hospital setting. We found high survival rates to hospital in both groups, suggesting that physician-staffed HEMS provide high-quality emergency airway management in trauma and non-trauma patients.

Conscientiousness is associated with longevity. As such, identifying the biological pathways linking personality to mortality is important. This study employs longitudinal data spanning >40 years to test prospective associations with Leukocyte Telomere Length (LTL), a potential marker of cellular aging. Because telomeres shorten over time, and are sensitive to oxidative stress, shorter LTL may reflect cumulative damage associated with negative health behaviors and past stressful events. We investigated childhood conscientiousness as a protective factor, expecting an association with longer LTL in adulthood, possibly reflecting slower LTL shortening. Potential lifespan pathways involving childhood trauma, smoking behaviors, and Body Mass Index (BMI) were explored. Childhood conscientiousness showed a small raw association with LTL ( r = .08, p = .04), although this effect did not persist when controlling for age and sex. Despite this lack of a direct effect on LTL, we detected an indirect effect operating jointly through BMI and smoking. Higher rates of childhood betrayal trauma were associated with shorter LTL. Contrary to our hypothesis that conscientiousness would buffer this effect, we found evidence for an interaction with childhood betrayal traumas where the association between childhood betrayal traumas and LTL was larger for those higher on conscientiousness in childhood.

This paper tests the hypothesis that the association between childhood maltreatment and adult personality dysfunction is at least partially attributable to insecure attachment, that is that attachment style mediates the relationship between childhood maltreatment and adult personality dysfunction. Associations between childhood trauma, as measured by the Childhood Trauma Questionnaire (CTQ), anxious and avoidant attachment in romantic relationships, as measured by the Experiences in Close Relationships-Revised (ECR-R), and five personality domains, as measured by the Severity Indices of Personality Problems (SIPP-118), were examined in a sample of 72 psychiatric inpatients. The SIPP-118 domains included relational capacities, identity integration, self-control, responsibility, and social concordance. The direct effect of childhood trauma on all SIPP-118 domains was not significant after controlling for the indirect effect of attachment. In regression modeling, a significant indirect effect of childhood trauma via adult attachment style was found for SIPP-118 relational capacities, identity integration, self-control, and social concordance. Specifically, anxious attachment was a significant mediator of the effect of childhood trauma on self-control, identity integration, and relational domains. These results suggest that childhood trauma impacts a broad range of personality domains and does so in large part through the pathway of anxious romantic attachment style.

Evidence suggests that maternal interpersonal trauma can adversely affect offspring health, but little is known about potential transmission pathways. We investigated whether interpersonal trauma exposure had direct and indirect associations with offspring social-emotional development at 12-months of age in an at-risk, home visited population. A retrospective cohort study was conducted of 1172 mother-child dyads who participated in a multi-site, early childhood home visiting program. Children were born January 2007 to June 2010 and data were collected at enrolment (prenatal/birth) through 12-months of age. Multivariable path analyses were used to examine the relationship between maternal interpersonal trauma, subsequent psychosocial mediators (maternal depressive symptoms, social support, and home environment), and the outcome of child social-emotional development measured with the Ages and Stages Questionnaire: Social-Emotional (ASQ:SE). Maternal interpersonal trauma was characterized as any previous exposure, the level of exposure, and type (e.g. abuse) of exposure. The prevalence of maternal interpersonal trauma exposure was 69.1%, and exposures ranged from 1 type (19.3%) to 7 types (2.3%). Interpersonal trauma was associated with a 3.6 point (95% confidence interval 1.8, 5.4) higher ASQ:SE score among offspring and indicated greater developmental risk. An estimated 23.4% of the total effect was mediated by increased maternal depressive symptoms and lower social support. Differential effects were observed by the level and type of interpersonal trauma exposure. Maternal interpersonal trauma exposures can negatively impact child social-emotional development, acting in part through maternal psychosocial factors. Future research is needed to further elucidate the mechanisms of intergenerational risk. © 2017 John Wiley & Sons Ltd.

Objectives While some studies have examined the deleterious effects of childhood bullying on adults, no studies to date have focused on the effects of bullying on Persons Living with HIV (PLH), a particularly at-risk population. PLH experience higher rates of childhood and adulthood physical and sexual abuse than the population at large, and experience of childhood abuse appears to be predictive of sexual and other risk behaviors in this population. Thus it remains critical to examine rates of childhood bullying and correlates of bullying in adult PLH. Methods A sample of 171 HIV-positive men over 18 years of age were recruited from the San Francisco Bay Area. All participants reported experiencing symptoms of traumatic stress. The participants were recruited as part of a larger study assessing a group intervention for individuals with HIV and symptoms of trauma. Self-report questionnaires were administered to assess participants’ exposure to bullying in childhood and trauma symptoms in adulthood. Results Bullying was commonly reported by men in the current sample, with 91% of the sample endorsing having experienced some level of bullying before age 18. Having been bullied in childhood was significantly (p < .05) associated with methamphetamine use in adulthood, difficulties with mood, and with symptoms of trauma. Results of a hierarchical regression equation found that report of bullying in childhood predicted additional, unique variance in trauma symptoms in adulthood above and beyond the effect of exposure to other forms of trauma, resulting in a better-fitting model. Conclusions The current study highlights the association between rate of childhood bullying and symptoms of trauma in adulthood, accounting for the effect of exposure to other forms of trauma. Given the impact of trauma symptoms on disease progression in PLH, exposure to bullying must be considered in any intervention aiming to reduce trauma symptoms or improve mental or physical health among HIV-positive populations.

Held, Philip; Owens, Gina P

The present pilot study examined the effects of a 4-week-long self-administered self-compassion training on trauma-related guilt and compared it to a stress inoculation control group. A total of 47 homeless male veterans who were living in transitional housing facilities volunteered to participate in this study. Participants were randomly assigned to either a self-compassion (N = 13) or a stress inoculation (N = 14) group and were asked to complete pre-, mid-, and postintervention assessments measuring changes in self-compassion, trauma-related guilt, and posttraumatic stress disorder severity. Participants in both interventions reported increased levels of self-compassion and equal reductions in trauma-related guilt. No other significant changes were noted. The results from this pilot study provide preliminary evidence for the use of self-compassion and stress inoculation trainings as effective interventions for trauma-related guilt. The findings also suggest that self-administered trainings in the form of workbooks may be a viable, cost-effective form of intervention for disadvantaged populations, such as homeless veterans in transitional housing, who may lack resources or access to professionals or paraprofessionals. The effects of both self-compassion training and stress inoculation training on the study variables and directions for future research on self-compassion and trauma-related guilt are discussed. © 2015 Wiley Periodicals, Inc.

To determine the association of procalcitonin (PCT) with trauma severity and post traumatic sepsis in children. The blood samples of 30 children with acute trauma in a Pediatric unit were collected for four consecutive days. The levels of PCT, IL-6, CRP and WBC were measured. The pediatric trauma score (PTS), length of stay in hospital, incidence of sepsis and clinical outcomes of the children were recorded. The value of PCT for predicting prognosis of children with trauma was compared with other inflammatory markers. Plasma PCT levels increased significantly in the patients in our study. Sepsis occurred in 23.33% of the patients. The patients with sepsis had higher levels of PCT than those with and without systemic inflammatory response syndrome (SIRS) and the healthy controls (P < 0.05). The peak level of PCT emerged on day 2 after trauma. The plasma PCT levels were positively correlated with trauma severity. The level of PCT on day 2 was an independent predictor for post-trauma sepsis and SIRS. Plasma PCT levels increase markedly in post trauma children. Plasma PCT of day 2 after trauma is an independent predictor of post-traumatic sepsis and SIRS complications. There is a significant correlation between the severity of injury and plasma PCT.

This is a retrospective review to determine demographics, presentation and injury characteristics of trauma deaths at Howard University Hospital over an 1-year period (1994-2005) and to make recommendations for education and prevention in the community based on our findings. Data was obtained from the Howard University Hospital trauma registry. From the study period 1994-2005, there was a total of 365 trauma deaths. The injuries sustained were mainly intentional, which accounted for almost 75% of cases--the majority of deaths being due to penetrating injuries. There was an almost two-fold increase in trauma deaths on Saturdays compared to the rest of the week. The demographics of our study population were similar to those reported in the trauma literature. These were younger patients and predominantly male. Unique to our population was the overwhelming predominance of African-American patients (90%). With these unique features, injury prevention would be better served focusing on social and community prevention and education rather than the usual methods of blunt-trauma prevention--e.g., pedestrian- and motor-vehicle-oriented policies, which may be more beneficial in other trauma systems.

According to Donabedian's health care quality model, improvements in the structure of care should lead to improvements in clinical processes that should in turn improve patient outcome. This model has been widely adopted by the trauma community but has not yet been validated in a trauma system. The objective of this study was to assess the performance of an integrated trauma system in terms of structure, process, and outcome and evaluate the correlation between quality domains. Quality of care was evaluated for patients treated in a Canadian provincial trauma system (2005-2010; 57 centers, n = 63,971) using quality indicators (QIs) developed and validated previously. Structural performance was measured by transposing on-site accreditation visit reports onto an evaluation grid according to American College of Surgeons criteria. The composite process QI was calculated as the average sum of proportions of conformity to 15 process QIs derived from literature review and expert opinion. Outcome performance was measured using risk-adjusted rates of mortality, complications, and readmission as well as hospital length of stay (LOS). Correlation was assessed with Pearson's correlation coefficients. Statistically significant correlations were observed between structure and process QIs (r = 0.33), and process and outcome QIs (r = -0.33 for readmission, r = -0.27 for LOS). Significant positive correlations were also observed between outcome QIs (r = 0.37 for mortality-readmission; r = 0.39 for mortality-LOS and readmission-LOS; r = 0.45 for mortality-complications; r = 0.34 for readmission-complications; 0.63 for complications-LOS). Significant correlations between quality domains observed in this study suggest that Donabedian's structure-process-outcome model is a valid model for evaluating trauma care. Trauma centers that perform well in terms of structure also tend to perform well in terms of clinical processes, which in turn has a favorable influence on patient outcomes.

Since appropriate and time-table methods in trauma care have an important impact on patients'outcome, we evaluated the effect of Advanced Trauma Life Support (ATLS) program on medical interns' performance in simulated trauma patient management. A descriptive and analytical study before and after the training was conducted on 24 randomly selected undergraduate medical interns from Imam Reza Hospital in Mashhad, Iran. On the first day, we assessed interns' clinical knowledge and their practical skill performance in confronting simulated trauma patients. After 2 days of ATLS training, we performed the same study and evaluated their score again on the fourth day. The two findings, pre- and post- ATLS periods, were compared through SPSS version 15.0 software. P values less than 0.05 were considered statistically significant. Our findings showed that interns'ability in all the three tasks improved after the training course. On the fourth day after training, there was a statistically significant increase in interns' clinical knowledge of ATLS procedures, the sequence of procedures and skill performance in trauma situations (P less than 0.001, P equal to 0.016 and P equal to 0.01 respectively). ATLS course has an important role in increasing clinical knowledge and practical skill performance of trauma care in medical interns.

A Comparison of Two Models of Risky Sexual Behavior During Late Adolescence.

Two models of risky sexual behavior (RSB) were compared in a community sample of late adolescents (N = 223). For the traumagenic model, early negative sexual experiences were posited to lead to an association between negative affect with sexual relationships. For the cognitive escape model, depressive affect was posited to lead to engagement in RSB as a way to avoid negative emotions. The current study examined whether depression explained the relationship between sexual trauma and RSB, supporting the cognitive escape model, or whether it was sexual trauma that led specifically to RSB, supporting the traumagenic model. Physical trauma experiences were also examined to disentangle the effects of sexual trauma compared to other emotionally distressing events. The study examined whether the results would be moderated by participant sex. For males, support was found for the cognitive escape model but not the traumagenic model. Among males, physical trauma and depression predicted engagement in RSB but sexual trauma did not. For females, support was found for the traumagenic and cognitive escape model. Among females, depression and sexual trauma both uniquely predicted RSB. There was an additional suppressor effect of socioeconomic status in predicting RSB among females. Results suggest that the association of trauma type with RSB depends on participant sex. Implications of the current study for RSB prevention efforts are discussed.

Does ethno-cultural betrayal in trauma affect Asian American/Pacific Islander college students' mental health outcomes? An exploratory study.

PubMed

Gómez, Jennifer M

Interpersonal trauma has deleterious effects on mental health, with college students experiencing relatively high rates of lifetime trauma. Asian American/Pacific Islanders (AAPIs) have the lowest rate of mental healthcare utilization. According to cultural betrayal trauma theory, societal inequality may impact within-group violence in minority populations, thus having implications for mental health. In the current exploratory study, between-group (interracial) and within-group (ethno-cultural betrayal) trauma and mental health outcomes were examined in AAPI college students. Participants (N = 108) were AAPI college students from a predominantly white university. Data collection concluded in December 2015. Participants completed online self-report measures. A multivariate analysis of variance revealed that when controlling for interracial trauma, ethno-cultural betrayal trauma significantly impacted dissociation, hallucinations, posttraumatic stress symptoms, and hypervigilance. The results have implications for incorporating identity, discrimination, and ethno-cultural betrayal trauma victimization into assessments and case conceptualizations in therapy.

Posttraumatic stress disorder and childhood trauma frequently co-occur. Both are associated with abnormal neural responses to salient emotion stimuli. As childhood trauma is a risk factor for posttraumatic stress disorder, differentiating between their neurophysiological effects is necessary to elucidate the neural pathways by which childhood trauma exposure contributes to increased posttraumatic stress disorder risks. Face-specific N170 evoked response potentials for backward-masked (non-conscious) and conscious threat (fear, angry) and non-threat (happy) faces were measured in 77 adults (18-64 years old, 64% women, 78% right-handed) symptomatic for posttraumatic stress disorder. Differences in N170 peak amplitudes for fear-versus-happy and angry-versus-happy faces at bilateral temporo-occipital (T5, T6) sites were computed. The effect of cumulative exposure to childhood interpersonal trauma, other childhood trauma, adult trauma, depression and posttraumatic stress disorder symptom severity on the N170 response was assessed using hierarchical multiple regression analyses. T5 N170 peak amplitudes for non-conscious fear-versus-happy faces were inversely related to cumulative childhood interpersonal trauma after accounting for socio-demographic, clinical symptom and other trauma factors. Posttraumatic stress disorder Avoidance was positively associated with N170 peak amplitudes for non-conscious fear-versus-happy faces, primarily due to reduced N170 responsivity to happy faces. Childhood interpersonal trauma exposure is associated with reduced discrimination between fear and happy faces, while avoidance symptom severity is associated with dampened responsivity to automatically processed happy faces in posttraumatic stress disorder adults. Results are discussed in terms of the likely contributions of impaired threat discrimination and deficient reward processing during neural processing of salient emotion stimuli, to increased risks of posttraumatic stress disorder onset and chronicity in childhood interpersonal trauma-exposed adults.

Following trauma exposure and PTSD, individuals with severe mental illness (SMI) frequently suffer a complex course of recovery complicated by reduced mental and physical health and increased substance abuse. The authors evaluated a theoretical PTSD-SMI model which theorizes that trauma, PTSD, depression, substance abuse, mental health, and physical health are interrelated and that PTSD mediates these relationships. Participants were ethnoracially diverse individuals diagnosed with SMI (N=175) who were assessed for trauma exposure, severity of PTSD and depression, substance abuse, and overall mental and physical health functioning. Pearson's correlations were utilized to examine the relationships between study domains. The mediating effects of PTSD were assessed using regression coefficients and the Sobel test for mediation. A majority of participants with SMI (89%) reported trauma exposure and 41% reported meeting diagnostic criteria for PTSD. On average, participants were exposed to over four types of traumatic events. Trauma, severity of PTSD and depression, substance abuse, and overall mental and physical health functioning were significantly interrelated. PTSD partially mediated the relationships between trauma and severity of depression and between trauma and overall mental health; PTSD fully mediated the trauma and overall physical health relationship. Within an ethnoracially diverse SMI sample, trauma exposure and PTSD comorbidity were high and associated with severity of depression, substance abuse, overall mental health and physical health functioning. Supporting our theoretical PTSD-SMI model, PTSD mediated the adverse effects of trauma exposure on participants' current severity of depression and overall mental and physical health functioning.

Childhood trauma is emerging as a risk factor for schizophrenia, but its mechanism with respect to etiology is unknown. One possible pathway is through leucocyte telomere length (LTL) shortening, a measure of cellular aging associated with trauma. This study examined early trauma and LTL shortening in schizophrenia and considered sex effects. The early trauma inventory (ETI) was administered to 48 adults with DSM-5 schizophrenia and 18 comparison participants. LTL was measured using qPCR. Cases had significantly more global trauma (F=4.10, p<0.01) and traumatic events (F=11.23, p<0.001), but case and control groups had similar LTL (1.91±0.74 and 1.83±0.62: p=0.68). The association of early trauma and LTL differed by sex in cases and controls (Fisher's R: Z<0.05). Significant negative associations were shown in male cases and, conversely, in female controls. For example, physical punishment was associated LTL shortening in males' cases (r=-0.429, p<01). Only female controls showed significant telomere shortening in association with early trauma. This data confirms the substantial excess of early trauma among schizophrenia cases. There were significant sex-differences in the relationship of the trauma to LTL, with only male cases showing the expected shortening. There were converse sex effects in the control group. Mean LTL was notably similar in cases and controls, despite the trauma-related shortening in male cases, cigarette smoking, older age and chronic illness of the cases. Factors may lengthen LTL in some schizophrenia cases. The converse sex differences in the cases are consistent with findings defective sexual differentiation in schizophrenia, consistent with other findings in the field. Copyright © 2018 Elsevier B.V.

Trauma remains one of the most frequent presentations in emergency departments. Imaging has established role in setting of acute trauma with ability to identify potentially fatal conditions. Adequate knowledge of health professionals regarding trauma imaging is vital for improved healthcare. In this work we try to assess knowledge of medical students regarding imaging in trauma as well as identify most effective way of imparting radiology education. This cross-sectional pilot study was conducted at Aga Khan University Medical College & Khyber Girls Medical College, to assess knowledge of medical students regarding imaging protocols practiced in initial management of trauma patients. Only 40 & 20% respectively were able to identify radiographs included in trauma series. Very few had knowledge of correct indication for Focused abdominal sonography in trauma. Clinical radiology rotation was reported as best way of learning radiology. Change in curricula & restructuring of clinical radiology rotation structure is needed to improve knowledge regarding Trauma imaging.

Previous research has demonstrated that a history of adult sexual assault (ASA) is associated with negative outcomes, including trauma symptomatology and fear of sexual intimacy. Disclosing sexual assault might be protective against such negative outcomes. To examine the indirect effect of trauma symptomatology on the association between disclosing ASA and current sexual functioning. Participants included 652 women 21 to 30 years old with a history of ASA recruited from the community. Participants completed self-report measurements on a computer. Separate models were performed, with sexual functioning divided into sexual desire, orgasm, and pain during sex. ASA disclosure was indirectly associated with sexual orgasm and pain during sex by trauma symptomatology. However, there was no indirect effect of trauma symptomatology on the relation between ASA disclosure and sexual desire. Disclosing experiences of ASA could serve a protective function by lessening trauma symptomatology, thereby mitigating impacts on aspects of sexual functioning, such as orgasm and pain.

Trauma and traumatic neurosis: Freud's concepts revisited.

PubMed

Zepf, Siegfried; Zepf, Florian D

2008-04-01

The authors examine Freud 's concepts of 'trauma', 'protective shield against stimuli ' and 'traumatic neurosis' in the light of recent findings. 'Protective shield against stimuli' is regarded as a biological concept which appears in mental life as the striving to avoid unpleasant affects. 'Trauma' is a twofold concept in that it relates to mental experience and links an external event with the specific after-effects on an individual 's psychic reality. A distinction needs to be made between mentally destructive trauma and affective trauma. A destructive trauma does not break through the protective shield but does breach the pleasure-unpleasure principle, so that in the course of its subsequent mastery it leads to a traumatic neurosis. An affective trauma can be warded off under the rule of the pleasure-unpleasure principle and leads to a psychoneurosis.

The Impact of Specific and Complex Trauma on the Mental Health of Homeless Youth.

This study investigates the relative impact of trauma experiences that occurred prior to and since becoming homeless on depressive symptoms, posttraumatic stress disorder (PTSD) symptoms, and self-injurious behaviors among a sample of homeless youth (N = 389). Youth (aged 13 to 25) who had been homeless or precariously housed in the past year completed a survey about housing history, experiences of violence and victimization, mental health, and service utilization. In addition to examining the impact associated with specific trauma types, we also considered the effect of "early-on" poly-victimization (i.e., cumulative number of reported traumas prior to homelessness) and the influence of a compound sexual trauma variable created to represent earlier complex trauma. This created-variable has values ranging from no reported trauma, single trauma, multiple non-sexual traumas, and multiple traumas that co-occurred with sexual abuse. Multivariate analyses revealed that specific traumatic experiences prior to homelessness, including sexual abuse, emotional abuse/neglect, and adverse home environment, predicted greater mental health symptoms. Poly-victimization did not add to the prediction of mental health symptoms after the inclusion of specific traumas. Results with early compound sexual trauma revealed significant differences between lower-order trauma exposures and multiple-trauma exposures. Specifically, experience of multiple traumas that co-occurred with sexual trauma was significantly more detrimental in predicting PTSD symptoms than multiple traumas of non-sexual nature. Findings support the utility of an alternate/novel conceptualization of complex trauma, and support the need to carefully evaluate complex traumatic experiences that occurred prior to homelessness, which can impact the design and implementation of mental health care and services for homeless youth. © The Author(s) 2014.

The relevance of emotional stimuli to threat and survival confers a privileged role in their processing. In PTSD, the ability of trauma-related information to divert attention is especially pronounced. Information unrelated to the trauma may also be highly distracting when it shares perceptual features with trauma material. Our goal was to study how trauma-related environmental cues modulate working memory networks in PTSD. We examined neural activity in participants performing a visual working memory task while distracted by task-irrelevant trauma and non-trauma material. Recent post-9/11 veterans were divided into a PTSD group (n = 22) and a trauma-exposed control group (n = 20) based on the Davidson trauma scale. Using fMRI, we measured hemodynamic change in response to emotional (trauma-related) and neutral distraction presented during the active maintenance period of a delayed-response working memory task. The goal was to examine differences in functional networks associated with working memory (dorsolateral prefrontal cortex and lateral parietal cortex) and emotion processing (amygdala, ventrolateral prefrontal cortex, and fusiform gyrus). The PTSD group showed markedly different neural activity compared to the trauma-exposed control group in response to task-irrelevant visual distractors. Enhanced activity in ventral emotion processing regions was associated with trauma distractors in the PTSD group, whereas activity in brain regions associated with working memory and attention regions was disrupted by distractor stimuli independent of trauma content. Neural evidence for the impact of distraction on working memory is consistent with PTSD symptoms of hypervigilance and general distractibility during goal-directed cognitive processing.

Methods We conducted a systematic review, across 19 databases, in which the titles of the three sets of guidelines – Guidelines for essential trauma care, Prehospital trauma care systems and Guidelines for trauma quality improvement programmes – were used as the search terms. Results were validated via citation analysis and expert consultation. Two authors independently reviewed each record of the guidelines’ implementation. Findings We identified 578 records that provided evidence of dissemination of WHO trauma care guidelines and 101 information sources that together described 140 implementation events. Implementation evidence could be found for 51 countries – 14 (40%) of the 35 low-income countries, 15 (32%) of the 47 lower-middle income, 15 (28%) of the 53 upper-middle-income and 7 (12%) of the 59 high-income. Of the 140 implementations, 63 (45%) could be categorized as needs assessments, 38 (27%) as endorsements by stakeholders, 20 (14%) as incorporations into policy and 19 (14%) as educational interventions. Conclusion Although WHO’s trauma care guidelines have been widely implemented, no evidence was identified of their implementation in 143 countries. More serial needs assessments for the ongoing monitoring of capacity for trauma care in health systems and more incorporation of the guidelines into both the formal education of health-care providers and health policy are needed.

To establish a database for pelvic trauma in Hunan Province, and to start the work of multicenter pelvic trauma registry.
 Methods: To establish the database, literatures relevant to pelvic trauma were screened, the experiences from the established trauma database in China and abroad were learned, and the actual situations for pelvic trauma rescue in Hunan Province were considered. The database for pelvic trauma was established based on the PostgreSQL and the advanced programming language Java 1.6.
 Results: The complex procedure for pelvic trauma rescue was described structurally. The contents for the database included general patient information, injurious condition, prehospital rescue, conditions in admission, treatment in hospital, status on discharge, diagnosis, classification, complication, trauma scoring and therapeutic effect. The database can be accessed through the internet by browser/servicer. The functions for the database include patient information management, data export, history query, progress report, video-image management and personal information management.
 Conclusion: The database with whole life cycle pelvic trauma is successfully established for the first time in China. It is scientific, functional, practical, and user-friendly.

Post-traumatic stress disorder is characterised by repeated intrusive imagery of the traumatic event. Despite alcohol's impairing effect on memory and frequent involvement in real-life trauma, virtually nothing is known of the interaction between alcohol and trauma memory. We aimed to investigate the acute alcohol effects on spontaneous memories following a trauma film as well as explicit memory for the film. Utilising an independent-group double-blind design, 48 healthy volunteers were randomly allocated to receive alcohol of 0.4 or 0.8 g/kg or a matched placebo drink. A stressful film was viewed post-drink. Skin conductance was monitored throughout and mood and dissociative symptoms were indexed. Volunteers recorded their spontaneous memories of the film daily in an online diary over the following week. Their explicit memory for both gist and details of the film was tested on day 7. Intriguingly, an inverted 'U' alcohol dose-response was observed on intrusive memories with a low dose of alcohol increasing memory intrusions while a high dose decreased intrusions. In contrast, explicit memory performance after 7 days showed a linear dose-response effect of alcohol with both recall and recognition decreasing as dose increased. These findings highlight a striking differential pattern of alcohol's effects on spontaneous memories as compared with explicit memories. Alcohol's effect on spontaneous memories may reflect a dose-dependent impairment of two separate memory systems integral to the processing of different aspects of a traumatic event.

Background Flashbacks (intrusive memories of a traumatic event) are the hallmark feature of Post Traumatic Stress Disorder, however preventative interventions are lacking. Tetris may offer a ‘cognitive vaccine’ [1] against flashback development after trauma exposure. We previously reported that playing the computer game Tetris soon after viewing traumatic material reduced flashbacks compared to no-task [1]. However, two criticisms need to be addressed for clinical translation: (1) Would all games have this effect via distraction/enjoyment, or might some games even be harmful? (2) Would effects be found if administered several hours post-trauma? Accordingly, we tested Tetris versus an alternative computer game – Pub Quiz – which we hypothesized not to be helpful (Experiments 1 and 2), and extended the intervention interval to 4 hours (Experiment 2). Methodology/Principal Findings The trauma film paradigm was used as an experimental analog for flashback development in healthy volunteers. In both experiments, participants viewed traumatic film footage of death and injury before completing one of the following: (1) no-task control condition (2) Tetris or (3) Pub Quiz. Flashbacks were monitored for 1 week. Experiment 1: 30 min after the traumatic film, playing Tetris led to a significant reduction in flashbacks compared to no-task control, whereas Pub Quiz led to a significant increase in flashbacks. Experiment 2: 4 hours post-film, playing Tetris led to a significant reduction in flashbacks compared to no-task control, whereas Pub Quiz did not. Conclusions/Significance First, computer games can have differential effects post-trauma, as predicted by a cognitive science formulation of trauma memory. In both Experiments, playing Tetris post-trauma film reduced flashbacks. Pub Quiz did not have this effect, even increasing flashbacks in Experiment 1. Thus not all computer games are beneficial or merely distracting post-trauma - some may be harmful. Second, the beneficial effects of Tetris are retained at 4 hours post-trauma. Clinically, this delivers a feasible time-window to administer a post-trauma “cognitive vaccine”. PMID:21085661

To quantify the incidence, timing, and risk of ischemic stroke after trauma in a population-based young cohort. We electronically identified trauma patients (<50 years old) from a population enrolled in a Northern Californian integrated health care delivery system (1997-2011). Within this cohort, we identified cases of arterial ischemic stroke within 4 weeks of trauma and 3 controls per case. A physician panel reviewed medical records, confirmed cases, and adjudicated whether the stroke was related to trauma. We calculated the 4-week stroke incidence and estimated stroke odds ratios (OR) by injury location using logistic regression. From 1,308,009 trauma encounters, we confirmed 52 trauma-related ischemic strokes. The 4-week stroke incidence was 4.0 per 100,000 encounters (95% confidence interval [CI] 3.0-5.2). Trauma was multisystem in 26 (50%). In 19 (37%), the stroke occurred on the day of trauma, and all occurred within 15 days. In 7/28 cases with cerebrovascular angiography at the time of trauma, no abnormalities were detected. In unadjusted analyses, head, neck, chest, back, and abdominal injuries increased stroke risk. Only head (OR 4.1, CI 1.1-14.9) and neck (OR 5.6, CI 1.03-30.9) injuries remained associated with stroke after adjusting for demographics and trauma severity markers (multisystem trauma, motor vehicle collision, arrival by ambulance, intubation). Stroke risk is elevated for 2 weeks after trauma. Onset is frequently delayed, providing an opportunity for stroke prevention during this period. However, in one-quarter of stroke cases with cerebrovascular angiography at the time of trauma, no vascular abnormality was detected. © 2017 American Academy of Neurology.

Uganda, like many low-income countries, has a tremendous volume of orthopaedic trauma injuries. The Uganda Sustainable Trauma Orthopaedic Program (USTOP) is a partnership between the University of British Columbia and Makerere University that was initiated in 2007 to reduce the consequences of neglected orthopaedic trauma in Uganda. USTOP works with local collaborators to build orthopaedic trauma capacity through clinical training, skills workshops, system support, technology development, and research. USTOP has maintained a multidisciplinary approach to training, involving colleagues in anaesthesia, nursing, rehabilitation, and sterile reprocessing. Since the program's inception, the number of trained orthopaedic surgeons practicing in Uganda has more than doubled. Many of these newly trained surgeons provide clinical care in the previously underserved regional hospitals. The program has also worked with collaborators to develop several technologies aimed at reducing the cost of providing orthopaedic care without compromising quality. As orthopaedic trauma capacity in Uganda advances, USTOP strives to continually evolve and provide relevant support to colleagues in Uganda.

Facial trauma.

Facial trauma. Patients with facial trauma must be assessed in a systematic way so as to avoid missing any injury. Severe and disfiguring facial injuries can be distracting. However, clinicians must first focus on the basics of trauma care, following the Advanced Trauma Life Support (ATLS) system of care. Maxillofacial trauma occurs in a significant number of severely injured patients. Life- and sight-threatening injuries must be excluded during the primary and secondary surveys. Special attention must be paid to sight-threatening injuries in stabilized patients through early referral to an appropriate specialist or the early initiation of emergency care treatment. The gold standard for the radiographic evaluation of facial injuries is computed tomography (CT) imaging. Nasal fractures are the most frequent isolated facial fractures. Isolated nasal fractures are principally diagnosed through history and clinical examination. Closed reduction is the most frequently performed treatment for isolated nasal fractures, with a fractured nasal septum as a predictor of failure. Ear, nose and throat surgeons, maxillofacial surgeons and ophthalmologists must all develop an adequate treatment plan for patients with complex maxillofacial trauma.

Freestanding children's hospitals may lack resources, especially surgical manpower, to meet American College of Surgeons trauma center criteria, and may organize trauma care in alternative ways. At a tertiary care children's hospital, attending trauma surgeons and anesthesiologists took out-of-hospital call and directed initial care for only the most severely injured patients, whereas pediatric emergency physicians directed care for patients with less severe injuries. Survival data were analyzed using TRISS methodology. A total of 903 trauma patients were seen by the system during the period 10/1/96-6/30/01. Median Injury Severity Score was 16, and 508 of patients had Injury Severity Score > or =15. There were 83 deaths, 21 unexpected survivors, and 13 unexpected deaths. TRISS analysis showed that z-score was 4.39 and W-statistic was 3.07. Mortality outcome from trauma in a pediatric hospital using this alternative approach to trauma care was significantly better than predicted by TRISS methodology.

Plasma opsonic activity as expressed by an alpha-2-globulin which stimulates hepatic Kupffer cell phagocytosis, and thus modulates RES clearance, was determined in patients at varying intervals following whole-body trauma. Plasma opsonic activity decreased markedly following trauma in both nonsurviving (NS) and surviving (S) trauma patients as compared to an age- and sex-matched group of healthy volunteers. The initial post-traumatic hypoopsonemia (0-72 hr) was more severe (p less than 0.01) in nonsurviving patients than surviving patients. Survivors following trauma manifested restoration of opsonin levels with a definite transient rebound hyperopsonemia during the recovery phase (11-30 days); nonsurviving patients exhibited persistent systemic alpha-2-globulin opsonic deficiency. On the basis of previous animal and human studies, the presently observed humoral deficits following trauma in patients could contribute to impairment of reticuloendothelial Kupffer cell clearance of blood-borne particulate matter such as fibrin, damaged platelets, and other altered autologous tissue. The importance of post-trauma RES dysfunction to survival following severe injury warrants further investigation and clinical consideration.

This study aimed to identify barriers and facilitators of mental health care for patients with trauma histories via qualitative methods with clinicians and administrators from primary care clinics for the underserved. Individual interviews were conducted, followed by a combined focus group with administrators from three jurisdictions; there were three focus groups with clinicians from each clinic system. Common themes were identified, and responses from groups were compared. Administrators and clinicians report extensive trauma histories among patients. Clinician barriers include lack of time, patient resistance, and inadequate referral options; administrators cite reimbursement issues, staff training, and lack of clarity about the term trauma. A key facilitator is doctor-patient relationship. There were differences in perceived barriers and facilitators at the institutional and clinical levels for mental health care for patients with trauma. Importantly, there is agreement about better access to and development of trauma-specific interventions. Findings will aid the development and implementation of trauma-focused interventions embedded in primary care. PMID:22551798

The power of contextual effects in forensic anthropology: a study of biasability in the visual interpretations of trauma analysis on skeletal remains.

The potential for contextual information to bias assessments in the forensic sciences has been demonstrated, in several forensic disiplines. In this paper, biasability potential within forensic anthropology was examined by analyzing the effects of external manipulations on judgments and decision-making in visual trauma assessment. Three separate websites were created containing fourteen identical images. Participants were randomly assigned to one website. Each website provided different contextual information, to assess variation of interpretation of the same images between contexts. The results indicated a higher scoring of trauma identification responses for the Mass grave context. Furthermore, a significant biasing effect was detected in the interpretation of four images. Less experienced participants were more likely to indicate presence of trauma. This research demonstrates bias impact in forensic anthropological trauma assessments and highlights the importance of recognizing and limiting cognitive vulnerabilities that forensic anthropologists might bring to the analysis. © 2014 American Academy of Forensic Sciences.

Posttraumatic Stress Disorder (PTSD) is characterised by dysfunctional appraisals of the trauma and its consequences including one's own symptoms. Experimental studies have shown that Cognitive Bias Modification-Appraisal (CBM-App) training can reduce dysfunctional interpretations and analog trauma symptoms. One important question is how to enhance the effects of CBM-App. Following work suggesting that sleep has beneficial effects on consolidation processes and can thus improve learning, the present study investigated whether a brief period of sleep (i.e., a nap) enhances the effects of CBM-App. All participants watched a stressful movie as an analogue trauma induction. After that, participants received either positive or negative CBM-App training. Within each training, half of the participants then had a 90-minute nap or watched a neutral movie. Results showed that the CBM training induced training-congruent appraisals. Sleep did not enhance this effect. Participants who slept, however, experienced fewer intrusive memories of the analogue trauma, but this effect was independent of the CBM condition. These results provide valuable information about the effects of sleep during a 90-minute nap period on encoding of analogue trauma and emotional learning in the context of appraisal, and highlight the importance of sleep as a focus for continued research.

Stress responding is linked to drug use, but little is known about stress responses in cannabis smokers. We investigated acute stress responding in cannabis smokers as a function of trauma exposure and sex, and relationships between stress responses and cannabis relapse. 125 healthy, non-treatment-seeking daily cannabis smokers (23F, 102 M) completed the Trier Social Stress Task (TSST), a standardized laboratory stressor; subsets also completed a trauma questionnaire (n = 106) and a laboratory cannabis relapse measure (n = 54). Stress responding was assessed with heart rate (HR), salivary cortisol (CORT), and self-rated mood. Cannabis smokers reporting at least one trauma exposure had higher CORT and anxiety overall compared to those reporting no trauma. Stress responding did not differ as a function of binary trauma exposure, although total number of exposures correlated positively with CORT and anxiety during stress. Females reported increased nervousness after stress relative to males matched to the females for cannabis and cigarette use. An interactive effect of sex and trauma on HR suggested that females with trauma exposure have increased cardiovascular stress responding relative to those without such exposure, with no differential effect in males. Stress responding did not predict laboratory cannabis relapse. We report differences in acute stress responding as a function of trauma, sex, and their interaction in a large sample of relatively homogenous cannabis smokers. Further investigation of how trauma impacts stress responding in male and female cannabis smokers, and how this relates to different aspects of cannabis use, is warranted.

Effective trauma resuscitation requires the coordinated efforts of an interdisciplinary team. Mental practice (MP) is defined as the mental rehearsal of activity in the absence of gross muscular movements and has been demonstrated to enhance acquiring technical and procedural skills. The role of MP to promote nontechnical, team-based skills for trauma has yet to be investigated. We randomized anaesthesiology, emergency medicine, and surgery residents to two-member teams randomly assigned to either an MP or control group. The MP group engaged in 20 minutes of MP, and the control group received 20 minutes of Advanced Trauma Life Support (ATLS) training. All teams then participated in a high-fidelity simulated adult trauma resuscitation and received debriefing on communication, leadership, and teamwork. Two blinded raters independently scored video recordings of the simulated resuscitations using the Mayo High Performance Teamwork Scale (MHPTS), a validated team-based behavioural rating scale. The Mann-Whitney U-test was used to assess for between-group differences. Seventy-eight residents provided informed written consent and were recruited. The MP group outperformed the control group with significant effect on teamwork behaviour as assessed using the MHPTS: r=0.67, p<0.01. MP leads to improvement in team-based skills compared to traditional simulation-based trauma instruction. We feel that MP may be a useful and inexpensive tool for improving nontechnical skills instruction effectiveness for team-based trauma care.

Protective Effect of Tropisetron on Rodent Hepatic Injury after Trauma-Hemorrhagic Shock through P38 MAPK-Dependent Hemeoxygenase-1 Expression

Tropisetron can decrease inflammatory cell responses and alleviate organ damage caused by trauma-hemorrhage, but the mechanism of these effects remains unknown. The p38 mitogen-activated protein kinase/hemeoxygenase-1 (p38 MAPK/HO-1) pathway exerts anti-inflammatory effects on different tissues. The aim of this study was to investigate whether p38 MAPK/HO-1 plays any role in the tropisetron-mediated attenuation of hepatic injury after trauma-hemorrhage. Male Sprague-Dawley rats underwent trauma-hemorrhage (mean blood pressure maintained at approximately 35–40 mmHg for 90 min), followed by fluid resuscitation. During resuscitation, several treatment regimens were administered: four doses of tropisetron alone (0.1, 0.3, 1, 3 mg/kg body weight), or a single dose of tropisetron (1 mg/kg body weight) with and without a p38 MAPK inhibitor (SB-203580, 2 mg/kg body weight) or HO antagonist (chromium-mesoporphyrin, 2.5 mg/kg body weight). Various parameters were measured, and the animals were sacrificed at 24 h post-resuscitation. The results showed that trauma-hemorrhage increased the following parameters: plasma concentrations of aspartate (AST) and alanine aminotransferases (ALT), hepatic myeloperoxidase (MPO) activity, and levels of cytokine-induced neutrophil chemoattractant-1 and -3 (CINC-1 and CINC-3), intercellular adhesion molecule-1 (ICAM-1), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and macrophage inflammatory protein-1α (MIP-1α). These parameters were significantly improved in the tropisetron-treated rats subjected to trauma-hemorrhage. Tropisetron treatment also increased hepatic p38 MAPK and HO-1 expression compared with vehicle-treated trauma-hemorrhaged rats. Co-administration of SB-203580 or chromium-mesoporphyrin with tropisetron abolished the tropisetron-induced beneficial effects on the above parameters and hepatic injury. These results suggest that the protective effect of tropisetron administration on alleviation of hepatic injury after trauma-hemorrhage is likely mediated through p38 MAPK-dependent HO-1 expression.

Variations of the corticotropin-releasing hormone receptor 1 (CRHR1) gene appear to moderate the development of depression after childhood trauma. Depression more frequently affects women than men. We examined sex differences in the effects of the CRHR1 gene on the relationship between childhood trauma and adult depression. We recruited 1,063 subjects from the waiting rooms of a public urban hospital. Childhood trauma exposure and symptoms of depression were assessed using dimensional rating scales. Subjects were genotyped for rs110402 within the CRHR1 gene. An independent sample of 78 subjects underwent clinical assessment, genotyping, and a dexamethasone/CRH test. The age range at recruitment was 18-77 years and 18-45, for the two studies respectively. In the hospital sample, the protective effect of the rs110402 A-allele against developing depression after childhood trauma was observed in men (N = 424), but not in women (N = 635). In the second sample, the rs110402 A-allele was associated with decreased cortisol response in the dexamethasone/CRH test only in men. In A-allele carriers with childhood trauma exposure women exhibited increased cortisol response compared men; there were no sex differences in A-allele carriers without trauma exposure. This effect may, however, not be related to gender differences per se, but to differences in the type of experienced abuse between men and women. CRHR x environment interactions in the hospital sample were observed with exposure to physical, but not sexual or emotional abuse. Physical abuse was the most common type of abuse in men in this cohort, while sexual abuse was most commonly suffered by women. Our results suggest that the CRHR1 gene may only moderate the effects of specific types of childhood trauma on depression. Gender differences in environmental exposures could thus be reflected in sex-specific CRHR1 x child abuse interactions.

Chronic depression has often been associated with childhood trauma. There may, however, be an interaction between personality pathology, childhood trauma, and chronic depression. This interaction has not yet been studied. This retrospective analysis is based on 279 patients contacted for a randomized trial in an outpatient psychotherapy center over a period of 18 months from 2010 to 2012. Current diagnoses of a personality disorder and presence of chronic depression were systematically assessed using the Structured Clinical Interview for DSM-IV. Retrospective reports of childhood trauma were collected using the short form of the Childhood Trauma Questionnaire (CTQ-SF). DSM-IV-defined chronic depression was the primary outcome. The association between chronic depression, childhood trauma, and personality disorders was analyzed using correlations. Variables that had at least a small effect on correlation analysis were entered into a series of logistic regression analyses to determine the predictors of chronic depression and the moderating effect of childhood trauma. The presence of avoidant personality disorder, but no CTQ-SF scale, was associated with the chronicity of depression (odds ratio [OR] = 2.20, P = .015). The emotional abuse subscale of the CTQ-SF did, however, correlate with avoidant personality disorder (OR = 1.15, P = .000). The level of emotional abuse had a moderating effect on the effect of avoidant personality disorder on the presence of chronic depression (OR = 1.08, P = .004). Patients who did not suffer from avoidant personality disorder had a decreased rate of chronic depression if they retrospectively reported more severe levels of emotional abuse (18.9% vs 39.7%, respectively). The presence of avoidant personality pathology may interact with the effect of childhood trauma in the development of chronic depression. This has to be confirmed in a prospective study.

Background One in nine American women will meet criteria for the diagnosis of posttraumatic stress disorder (PTSD) in their lifetime. Although twin studies suggest genetic influences account for substantial variance in PTSD risk, little progress has been made in identifying variants in specific genes that influence liability to this common, debilitating disorder. Methods and design We are using the unique resource of the Nurses Health Study II, a prospective epidemiologic cohort of 68,518 women, to conduct what promises to be the largest candidate gene association study of PTSD to date. The entire cohort will be screened for trauma exposure and PTSD; 3,000 women will be selected for PTSD diagnostic interviews based on the screening data. Our nested case-control study will genotype1000 women who developed PTSD following a history of trauma exposure; 1000 controls will be selected from women who experienced similar traumas but did not develop PTSD. The primary aim of this study is to detect genetic variants that predict the development of PTSD following trauma. We posit inherited vulnerability to PTSD is mediated by genetic variation in three specific neurobiological systems whose alterations are implicated in PTSD etiology: the hypothalamic-pituitary-adrenal axis, the locus coeruleus/noradrenergic system, and the limbic-frontal neuro-circuitry of fear. The secondary, exploratory aim of this study is to dissect genetic influences on PTSD in the broader genetic and environmental context for the candidate genes that show significant association with PTSD in detection analyses. This will involve: conducting conditional tests to identify the causal genetic variant among multiple correlated signals; testing whether the effect of PTSD genetic risk variants is moderated by age of first trauma, trauma type, and trauma severity; and exploring gene-gene interactions using a novel gene-based statistical approach. Discussion Identification of liability genes for PTSD would represent a major advance in understanding the pathophysiology of the disorder. Such understanding could advance the development of new pharmacological agents for PTSD treatment and prevention. Moreover, the addition of PTSD assessment data will make the NHSII cohort an unparalleled resource for future genetic studies of PTSD as well as provide the unique opportunity for the prospective examination of PTSD-disease associations.

The present study aims to identify possible mechanisms explaining this transmission among families of Holocaust Survivors (HS). We hypothesized that the high level of depressive and anxiety disorders (DAD) among HS impairs family systems, which results in damaging coping strategies of their children (CHS) yielding a higher level of DAD. 49 CHS completed the Resilience Scale for Adults, the Hopkins Symptom Check List-25, the 13-Item Sense of Coherence (SOC) scale, and the Family Adaptability and Cohesion Scale. We test a mediation model with Family types as the predictor; coping strategies (i.e. Resilience or SOC) as the mediator; and DAD as the outcome variable. Results confirm that the CHS׳ family types are more often damaged than in general population. Moreover, growing in a damaged family seems to impede development of coping strategies and, therefore, enhances the occurrence of DAD. The present investigation is correlational and should be confirmed by other prospective investigations. At a theoretical level we propose a mechanism of transmission of the noxious effects of a major trauma from one generation to the next through family structure and coping strategies. At a clinical level, our results suggest to investigate the occurrence of trauma among parents of patients consulting for DAD and to reinforce their coping strategies. Copyright © 2014 Elsevier B.V.
