Prospective validation of a hospital triage predictive model to decrease undertriage: an EAST multicenter study. Trauma Surg Acute Care Open 2024; 9:e001280. [PMID: 38737811 PMCID: PMC11086287 DOI: 10.1136/tsaco-2023-001280] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Accepted: 03/23/2024] [Indexed: 05/14/2024] Open
Abstract
Background Tiered trauma team activation (TTA) allows systems to optimally allocate resources to an injured patient. Target undertriage and overtriage rates of <5% and <35% are difficult for centers to achieve, and performance variability exists. The objective of this study was to optimize and externally validate a previously developed hospital trauma triage prediction model to predict the need for emergent intervention in 6 hours (NEI-6), an indicator of need for a full TTA. Methods The model was previously developed and internally validated using data from 31 US trauma centers. Data were collected prospectively at five sites using a mobile application which hosted the NEI-6 model. A weighted multiple logistic regression model was used to retrain and optimize the model using the original data set and a portion of data from one of the prospective sites. The remaining data from the five sites were designated for external validation. The area under the receiver operating characteristic curve (AUROC) and the area under the precision-recall curve (AUPRC) were used to assess the validation cohort. Subanalyses were performed for age, race, and mechanism of injury. Results 14 421 patients were included in the training data set and 2476 patients in the external validation data set across five sites. On validation, the model had an overall undertriage rate of 9.1% and overtriage rate of 53.7%, with an AUROC of 0.80 and an AUPRC of 0.63. Blunt injury had an undertriage rate of 8.8%, whereas penetrating injury had 31.2%. For those aged ≥65, the undertriage rate was 8.4%, and for Black or African American patients the undertriage rate was 7.7%. Conclusion The optimized and externally validated NEI-6 model approaches the recommended undertriage and overtriage rates while significantly reducing variability of TTA across centers for blunt trauma patients. The model performs well for populations that traditionally have high rates of undertriage. Level of evidence 2.

Abstract
Introducción. El trauma es una de las entidades con mayor morbimortalidad en el mundo. Los equipos especializados en la atención del paciente traumatizado son llamados <<equipos de trauma>>. Dichos equipos surgieron de la necesidad de brindar tratamiento oportuno multidisciplinario a individuos con heridas que condicionan gran severidad en la guerra; sin embargo, con el paso del tiempo se trasladaron al ámbito civil, generando un impacto positivo en términos de tiempos de atención, mortalidad y morbilidad.
El objetivo de este estudio fue describir el proceso de desarrollo de los equipos de trauma a nivel mundial y la experiencia en nuestra institución en el suroccidente colombiano.
Métodos. Se realizó una búsqueda en la base de datos PUBMED, que incluyó revisiones sistemáticas, metaanálisis, revisiones de Cochrane, ensayos clínicos y series de casos.
Resultados. Se incluyeron 41 estudios para esta revisión narrativa, y se observó que el tiempo de permanencia en el Emergencias, el tiempo de traslado a cirugía, la mortalidad y las complicaciones asociadas al trauma fueron menores cuando se implementan equipos de trauma.
Discusión. El diseño de un sistema de atención y valoración horizontal de un paciente con traumatismos severos produce un impacto positivo en términos de tiempos de atención, mortalidad y morbilidad. Se hace necesario establecer los parámetros operativos necesarios en las instituciones de salud de alta y mediana complejidad en nuestro país para implementar dichos equipos de trabajo.

Abstract
Objective To investigate the effects of trauma center establishment on the clinical characteristics and outcomes of trauma patients with traumatic brain injury (TBI). Methods We enrolled 322 patients with severe trauma and TBI from January 2015 to December 2016. Clinical factors, indexes, and outcomes were compared before and after trauma center establishment (September 2015). The outcome was the Glasgow outcome scale classification at 3 months post-trauma. Results Of the 322 patients, 120 (37.3%) and 202 (62.7%) were admitted before and after trauma center establishment, respectively. The two groups were significantly different in age (p=0.038), the trauma location within the city (p=0.010), the proportion of intensive care unit (ICU) admissions (p=0.001), and the emergency room stay time (p<0.001). Mortality occurred in 37 patients (11.5%). Although the preventable death rate decreased from before to after center establishment (23.1% vs. 12.5%), the difference was not significant. None of the clinical factors, indexes, or outcomes were different from before to after center establishment for patients with severe TBI (Glasgow coma scale score ≤8). However, the proportion of inter-hospital transfers increased and the time to emergency room arrival was longer in both the entire cohort and patients with severe TBI after versus before trauma center establishment. Conclusion We confirmed that for patients with severe trauma and TBI, establishing a trauma center increased the proportion of ICU admissions and decreased the emergency room stay time and preventable death rate. However, management strategies for handling the high proportion of inter-hospital transfers and long times to emergency room arrival will be necessary.

Abstract
Background: The Korean Ministry of Health and Welfare decided to establish a trauma medical service system to reduce preventable deaths. OO hospital in Gangwon Province was selected as a regional trauma center and was inaugurated in 2015. Objectives: This study examines the impact of this center, comparing mortality and other variables before and after inaugurating the center. Methods: Severely injured patients (injury severity score > 15) presenting to OO hospital between January 2014 and December 2016 were enrolled and categorized into two groups: before trauma center (n = 365) and after trauma center (n = 904). Patient characteristics, variables, and patient outcomes (including mortality rate) before and after the establishment of trauma centers were compared accordingly for both groups. Risk factors for in-hospital mortality were also identified. Results: Probability of survival using trauma and injury severity score (%) method was significantly lower in the after trauma center group (81.3 ± 26.1) than in the before trauma center group (84.7 ± 21.0) (p = 0.014). In-hospital mortality rates were similar in both groups (before vs after trauma center group: 13.2% vs 14.2%; p = 0.638). The Z and W statistics revealed higher scores in the after trauma center group than in the before trauma center group (Z statistic, 4.69 vs 1.37; W statistic, 4.52 vs 2.10); 2.42 more patients (per 100 patients) survived after trauma center establishment. Conclusion: Although the mortality rates of trauma patients remained unchanged after the trauma center establishment, the Z and W statistics revealed improvements in the quality of care.

Abstract
OBJECTIVE We conducted a study to validate the effectiveness of the Korean criteria for trauma team activation (TTA) and compared its results with a two-tiered system. METHODS This observational study was based on data from the Korean Trauma Data Bank. Within the study period, 1,628 trauma patients visited our emergency department, and 739 satisfied the criteria for TTA. The rates of overtriage and undertriage in the Korean one-tiered system were compared with the two-tiered system recommended by the American College of Surgery-Committee on Trauma. RESULTS Most of the patient's physiologic factors reflected trauma severity levels, but anatomical factors and mechanism of injury did not show consistent results. In addition, while the rate of overtriage (64.4%) was above the recommended range according to the Korean criteria, the rate of undertriage (4.0%) was within the recommended range. In the simulated two-tiered system, the rate of overtriage was reduced by 5.5%, while undertriage was increased by 1.8% compared to the Korean activation system. CONCLUSION The Korean criteria for TTA showed higher rates of overtriage and similar undertriage rates compared to the simulated two-tier system. Modification of the current criteria to a two-tier system with special considerations would be more effective for providing optimum patient care and medical resource utilization.

Abstract
BACKGROUND Despite the presence of a tiered in-hospital trauma triage system for the past decade, trauma centers still struggle with a definitive list of highest level activation criteria. In 2002, the American College of Surgeons (ACS) mandated 6 criteria for highest level activation. However, it is unknown if pediatric trauma centers follow these criteria. The purpose of this study is to identify and categorize the highest level pediatric trauma criteria used by pediatric trauma centers in the United States. METHODS In collaboration with the ACS, we reviewed activation criteria for highest level trauma activation for all ACS-verified level I pediatric trauma centers in the United States. Criteria were sorted by 2 reviewers into categories of indicators used for activation: patient demographic, physiologic, anatomic, intervention/resource usage, mechanism, and other. RESULTS A total of 51 unique criteria for highest level trauma activation were identified from 54 (96%) of 56 level I pediatric trauma centers. Each center used between 1 and 29 criteria. A total of 42.6% of pediatric trauma centers followed all 6 criteria recommended by ACS. The most commonly omitted criterion was emergency physician discretion. The most common criteria not included in the ACS recommendations, but included in the highest level activation criteria, were amputation proximal to wrist or ankle (63%), and spinal cord injury/paralysis (63%). CONCLUSIONS There is wide variation in the criteria used for highest level trauma activation among pediatric trauma centers. Further research investigating individual or grouped criteria to determine the most sensitive and specific criteria are necessary for appropriate triage and resource usage.

Abstract
Early after injury, local tissue damage induces a local and systemic inflammatory response that activates the immune system and leads to the development of systemic inflammatory response syndrome (SIRS). This post-traumatic response often results in uncontrolled release of inflammatory mediators and over-activation of the immune system, which occasionally results in multiple organ dysfunction syndrome (MODS). In parallel, a state of immunosuppression develops. This counter-regulating suppression of different cellular and humoral immune functions has been termed "compensatory anti-inflammatory response syndrome (CARS)." Both SIRS and CARS occur simultaneously even in the initial phase after injury. Pro- and anti-inflammatory cytokines have been suggested to play a major role in development of SIRS, although the degree of involvement of the different cytokines is quite disparate. While TNF-α and IL-1β are quite irrelevant for predicting organ dysfunction, IL-6 is the parameter that best predicts mortality. The hyperinflammatory state seems to be the cause of post-traumatic immunosuppression and heat shock proteins (HSPs), which have been proposed as one of the endogenous stimuli for the deterioration of the immune system acting as danger-associated molecular patterns (DAMPs). Extracellular HSPA1A released from injured tissues increase up to ten times immediately after trauma and even more in patients with MODS. It has powerful immune properties that could contribute to post-traumatic immunosuppression through several mechanisms that have been previously described, so HSPs could represent trauma-associated immunomodulatory mediators. For this reason, HSPA1A has been suggested to be a helpful early prognostic biomarker of trauma after severe injury: serial quantification of serum HSPA1A and anti-Hsp70 concentrations in the first hours after trauma is proposed to be used as a predictive biomarker of MODS and immunosuppression development in polytraumatized patients.

Abstract
BACKGROUND National guidelines recommend that prehospital and emergency department (ED) criteria identify patients who might benefit from trauma center triage and highest-level trauma team activation. However, some patients who are seemingly "stable" in the field and do not meet the standard criteria for trauma activation still die. OBJECTIVES The purpose of this study was to identify these at-risk patients to potentially improve triage algorithms. METHODS Patients enrolled in the National Trauma Data Bank (2007-2012) were included. All adult blunt trauma patients that were stable in the field and upon arrival to the ED (defined as a Glasgow Coma Scale score of 13-15, a heart rate ≤120 beats/min, systolic blood pressure ≥90 mm Hg, and diastolic blood pressure ≤200 mm Hg) and did not meet the standard criteria for the highest-level trauma team activation as defined by the American College of Surgeons were included. Demographic, clinical, and injury data including comorbidities, ED vitals, and outcome were collected. Regression models were used to identify independent risk factors for mortality. RESULTS A total of 1,003,350 patients were stable in both the field and ED. Of these 11,010 (1.1%) died, including 1785 (0.2%) who died within 24 hours of hospital admission. The mortality in patients ≥60 years of age was 2.6%, and in patients ≥60 years of age with either a cerebrovascular accident (CVA) or congestive heart failure (CHF) was 5.4%. Age ≥60 years was a significant independent predictor of early mortality (odds ratio [OR] 4.53, p < 0.001). CHF (OR 1.88, p < 0.001) and a history of stroke (OR 1.52, p < 0.001) were also significant independent predictors of mortality. CONCLUSIONS Despite apparent evidence of both prehospital stability and stability upon arrival to the ED, patients ≥60 years of age and with a history of CHF or CVA have a significantly increased risk of early mortality after blunt trauma. These patients are at risk for subsequent clinical deterioration and should be considered for early transfer to a trauma center with highest-level activation.

Abstract
Background Trauma is a leading cause of death among adults aged < 44 years, and optimal care is a challenge. Evidence supports the centralization of trauma facilities and the use multidisciplinary trauma teams. Because knowledge is sparse on the existing distribution of trauma facilities and the organisation of trauma care in Denmark, the aim of this study was to identify all Danish facilities that care for traumatized patients and to investigate the diversity in organization of trauma management. Methods We conducted a systematic observational cross-sectional study. First, all hospitals in Denmark were identified via online services and clarifying phone calls to each facility. Second, all trauma care manuals on all facilities that receive traumatized patients were gathered. Third, anesthesiologists and orthopedic surgeons on call at all trauma facilities were contacted via telephone for structured interviews. Results A total of 22 facilities in Denmark were found to receive traumatized patients. All facilities used a trauma care manual and all had a multidisciplinary trauma team. The study found three different trauma team activation criteria and nine different compositions of teams who participate in trauma care. Training was heterogeneous and, beyond the major trauma centers, databases were only maintained in a few facilities. Conclusion The study established an inventory of the existing Danish facilities that receive traumatized patients. The trauma team activation criteria and the trauma teams were heterogeneous in both size and composition. A national database for traumatized patients, research on nationwide trauma team activation criteria, and team composition guidelines are all called for.

Abstract
PURPOSE The primary objective of this study was to determine the risk factors associated with undertriage and the risk factors for mortality among the undertriaged patients at a level I safety-net trauma center. METHODS A retrospective analysis was performed of all trauma patients who presented to a level I safety-net trauma center with an injury severity score >15 over a 2-year period (2013-2014). Univariate and multivariate regression analyses were used to determine the risk factors predictive of undertriage in major trauma patients (injury severity score >15) and of mortality in undertriaged patients. RESULTS During the 2-year study period, 334 of 2,485 admitted trauma patients presented with major trauma and were included in our study. From the univariate analysis, variables that were found to be independently associated with mortality in undertriaged patients included intubation, Glasgow Coma Scale score, revised trauma score, and dementia. Independent risk factors that were found to be significantly associated with undertriage in severely injured trauma patients included Glasgow Coma Scale score, motor vehicle crash, falls, revised trauma score, systolic blood pressure, heart rate, intubation, and dementia. When a multivariate analysis was performed to evaluate the statistically significant risk factors, dementia was found to be significantly associated with undertriage in severely injured trauma patients. CONCLUSION Severely injured trauma patients with dementia are at significant risk for undertriage. Early identification of these risk factors while triaging at a level I safety-net trauma center could translate into improved patient outcomes following severe trauma.

Abstract
The type of medical review before an adverse event influences patient outcome. Delays in the up-transfer of patients requiring intensive care are associated with higher mortality rates. Timely detection and response to a deteriorating patient constitute an important function of the rapid response system (RRS). The activation of the RRS for at-risk patients constitutes the system’s afferent limb. Afferent limb failure (ALF), an important performance measure of rapid response systems, constitutes a failure to activate a rapid response team (RRT) despite criteria for calling an RRT. There are diurnal variations in hospital staffing levels, the performance of rapid response systems and patient outcomes. Fewer ward-based nursing staff at night may contribute to ALF. The diurnal variability in RRS activity is greater in unmonitored units than it is in monitored units for events that should result in a call for an RRT. RRT events include a significant abnormality in either the pulse rate, blood pressure, conscious state or respiratory rate. There is also diurnal variation in RRT summoning rates, with most activations occurring during the day. The reasons for this variation are mostly speculative, but the failure of the afferent limb of RRT activation, particularly at night, may be a factor. The term “circadian variation/rhythm” applies to physiological variations over a 24-h cycle. In contrast, diurnal variation applies more accurately to extrinsic systems. Circadian rhythm has been demonstrated in a multitude of bodily functions and disease states. For example, there is an association between disrupted circadian rhythms and abnormal vital parameters such as anomalous blood pressure, irregular pulse rate, aberrant endothelial function, myocardial infarction, stroke, sleep-disordered breathing and its long-term consequences of hypertension, heart failure and cognitive impairment. Therefore, diurnal variation in patient outcomes may be extrinsic, and more easily modifiable, or related to the circadian variation inherent in human physiology. Importantly, diurnal variations in the implementation and performance of the RRS, as gauged by ALF, the RRT response to clinical deterioration and any variations in quality and quantity of patient monitoring have not been fully explored across a diverse group of hospitals.

Abstract
BACKGROUND Trauma team activation (TTA) criteria were first implemented in the Emergency Department (ED) of Songklanagarind Hospital in 2009 to treat severe trauma patients. PURPOSE To determine the efficacy of the TTA criteria on the acute trauma care process in the ED and the 28-day mortality rate. METHODS A 1-year prospective cohort study was conducted at the ED. Trauma patients who were 18 years old and over who met the TTA criteria were enrolled. Demographic data, physiologic parameters, ED length of stay (EDLOS), and the injury severity score (ISS) were recorded. Multiple logistic regression was used to determine the factors affecting 28-day mortality. Institutional review board approval was obtained from the Prince of Songkla University. RESULTS A total of 80 patients (74 male and 6 female) were eligible with a mean age of 34.3 years old. Shock, penetrating torso injury, and pulse rate >120 beats per minute were the three most common criteria for trauma team consultation. At the ED, 9 patients (11.3 %) were non-survivors, 30 patients (37.5 %) needed immediate operation, and 41 patients (51.2 %) were admitted. All of the arrest patients died (p < 0.0001). The median time of EDLOS was 85 min: 68 min in the non-survivor group and 120 min in the survivor group (p = 0.028). The median ISS was 21.0 (1-75): 25.0 in the non-survivor group and 17.0 in the survivor group. When compared with pilot data prior to TTA implementation, the median time of EDLOS improved from 184 to 85 min and the 28-day mortality rate decreased from 66.7 to 46.3 %. The high ISS was a predictor of death. CONCLUSION The trauma team activation criteria improved acute trauma care in the ED which was demonstrated by the decreased EDLOS and mortality rate. A high ISS is the sole parameter predicting mortality.

Abstract
Introduction. Severity and outcome assessments are crucial in trauma. Our aim was to describe the role of a group of cytokines (TNFα, IL-6, IL-10, and HMGB-1) and ICAM-1 as severity and outcome assessment tools and their kinetics in the first 72 h after severe trauma. Materials and Methods. Authors designed a prospective cohort study of severe polytrauma patients (ISS > 15) in a level 1 Trauma Centre. Cytokines and ICAM-1 levels and Th1/Th2 ratios were assessed at admission, 24, 48, and 72 h. SIRS, SIRS with hypoperfusion, and shock were identified. Outcomes considered were ICU admission, ARDS, MODS, and death. Results. Ninety-nine patients were enrolled (median ISS: 29 and age 31). There was an early release of pro- and anti-inflammatory mediators with higher values at admission (except for ICAM-1). On admission, IL-6 was associated with ISS, IL-10 with SIRS with hypoperfusion, and HMGB-1 with shock. Several cytokines were associated with outcomes, especially IL-6 and IL-10 at 72 h with MODS and death. Low TNFα/IL-10 and IL-6/IL-10 ratios at 24 and 72 h were associated with MODS and death. Conclusions. Pro- and anti-inflammatory responses occur simultaneously and earlier after injury. Cytokines may be useful for outcome assessment, especially IL-6 and IL-10. Low Th1/Th2 ratio at 24 to 72 h is associated with MODS and death.

Abstract
Purpose Trauma team activation (TTA) has been shown to have fundamental impact on trauma patients' outcomes. The purpose of this study was to evaluate the short-term outcomes of use of a new TTA protocol in the management of major trauma patients who underwent exploratory laparotomy. Methods The medical records of trauma patients who had been treated by the new TTA protocol (NT) over 18 months were compared with those of trauma patients treated by the old TTA protocol (OT) over 18 months. Comparisons between the two groups in terms of the time interval between accident and emergency room (ER) arrival, between ER arrival and CT scanning, between ER arrival and operating room (OR) presentation, between accident and OR presentation, mean intensive care unit (ICU) stay, mean hospital stay, mortality within 24 hours, mean mortality within one month, and overall mortality were performed using the Pearson chi-squared test and Student t-test. Results The time interval between accident and ER arrival, between ER arrival and CT scanning, between ER arrival and OR presentation, and between accident and OR presentation was found to have decreased significantly with the use of NT compared to OT. However, the mean ICU stay, mean hospital stay, mortality within 24 hours, mortality within one month, and overall mortality were found not to have improved. Conclusion While initiation of early TTA can shorten the time interval in the management of trauma patients, it may not improve patient outcomes.

Abstract
The major trauma team relies on an efficient, communicative team to ensure patients receive the best quality care. This requires a comprehensive handover, rapid systematic review, and early management of life- and limb-threatening injuries. These multiple injured patients often present with complex conditions in a dynamic situation. The importance of team work, communication, senior decision-making, and documentation cannot be underestimated.

Abstract
BACKGROUND The Amberg-Schwandorf Algorithm for Primary Triage (ASAV) is a novel primary triage concept specifically for physician manned emergency medical services (EMS) systems. In this study, we determined the diagnostic reliability and the time requirements of ASAV triage. METHODS Seven hundred eighty triage runs performed by 76 trained EMS providers of varying professional qualification were included into the study. Patients were simulated using human dummies with written vital signs sheets. Triage results were compared to a standard solution, which was developed in a modified Delphi procedure. Test performance parameters (e.g. sensitivity, specificity, likelihood ratios (LR), under-triage, and over-triage) were calculated. Time measurements comprised the complete triage and tagging process and included the time span for walking to the subsequent patient. Results were compared to those published for mSTaRT. Additionally, a subgroup analysis was performed for employment status (career/volunteer), team qualification, and previous triage training. RESULTS For red patients, ASAV sensitivity was 87%, specificity 91%, positive LR 9.7, negative LR 0.139, over-triage 6%, and under-triage 10%. There were no significant differences related to mSTaRT. Per patient, ASAV triage required a mean of 35.4 sec (75th percentile 46 sec, 90th percentile 58 sec). Volunteers needed slightly more time to perform triage than EMS professionals. Previous mSTaRT training of the provider reduced under-triage significantly. There were significant differences in time requirements for triage depending on the expected triage category. CONCLUSIONS The ASAV is a specific concept for primary triage in physician governed EMS systems. It may detect red patients reliably. The test performance criteria are comparable to that of mSTaRT, whereas ASAV triage might be accomplished slightly faster. From the data, there was no evidence for a clinically significant reliability difference between typical staffing of mobile intensive care units, patient transport ambulances, or disaster response volunteers. Up to now, there is no clinical validation of either triage concept. Therefore, reality based evaluation studies are needed.

Abstract
The introduction of trauma teams has improved patient outcome independently. The aim of establishing a trauma team is to ensure the early mobilization and involvement of more experienced medical staff and thereby to improve patient outcome. The team approach allows for distribution of the several tasks in assessment and resuscitation of the patient in a 'horizontal approach', which may lead to a reduction in time from injury to critical interventions and thus have a direct bearing on the patient's ultimate outcome. A trauma team leader or supervisor, who coordinates the resuscitation and ensures adherence to guidelines, should lead the trauma team. There is a major national and international variety in trauma team composition, however crucial are a surgeon, an Emergency Medicine physician or both and anaesthetist. Advanced Trauma Life Support training, simulation-based training, and video review have all improved patient outcome and trauma team performance. Developments in the radiology, such as the use of computed tomography scanning in the emergency room and the endovascular treatment of bleeding foci, have changed treatment algorithms in selected patients. These developments and new insights in shock management may have a future impact on patient management and trauma team composition.

Abstract
Introduction: To determine if increased trauma team response results in alterations in resource use in a population of children <6 years, especially in those least injured. Methods: We conducted a retrospective before and after study of children <6 years sustaining blunt trauma and meeting defined prehospital criteria. We compared hospitalization rates and missed injuries (injuries identified after discharge from the emergency department/hospital) among patients with and without an upgraded trauma team response. We compared the computed tomography (CT) rate and laboratory testing rate among minimally injured patients (Injury Severity Score [ISS] 6). Results: We enrolled 352 patients with 180 (mean age 2.7 ± 1.5 years) in the upgrade cohort and 172 (mean age 2.6 ± 1.5 years) in the no-upgrade cohort. Independent predictors of hospital admission in a regression analysis included: Glasgow Coma Scale <14 (odds ratio [OR]=11.4, 95% confidence interval [CI] 2.3, 56), ISS (OR=1.55, 95% CI 1.33, 1.81), and evaluation by the upgrade trauma team (OR=5.66, 95% CI 3.14, 10.2). In the 275 patients with ISS <6, CT (relative risk=1.34, 95% CI 1.09, 1.64) and laboratory tests (relative risk=1.71, 95% CI 1.39, 2.11) were more likely to be obtained in the upgrade cohort as compared to the no-upgrade cohort. We identified no cases of a missed diagnosis. Conclusion: Increasing the trauma team response based upon young age results in increased resource use without altering the rate of missed injuries. In hospitals with emergency department physicians capable of evaluating and treating injured children, increasing ED trauma team resources solely for young age of the patient is not recommended.

Abstract
Background Traumatic brain injury (TBI) constitutes the leading cause of posttraumatic mortality. Practically, the major interventions required to treat TBI predicate expedited transfer to CT after excluding other immediately life-threatening conditions. At our center, trauma responses variably consist of either full trauma activation (FTA) including an attending trauma surgeon or a non-trauma team response (NTTR). We sought to explore whether FTAs expedited the time to CT head (TTCTH). Methods Retrospective review of augmented demographics of 88 serious head injuries identified from a Regional Trauma Registry within one year at a level I trauma center. The inclusion criteria consisted of a diagnosis of head injury recorded as intubated or GCS < 13; and CT-head scanning after arriving the emergency department. Data was analyzed using STATA. Results There were 58 FTAs and 30 NTTRs; 86% of FTAs and 17% of NTTRs were intubated prehospital out of 101 charts reviewed in detail; 13 were excluded due to missing data. Although FTAs were more seriously injured (median ISS 29, MAIS head 19, GCS score at scene 6.0), NTTRs were also severely injured (median ISS 25, MAIS head 21, GCS at scene 10) and older (median 54 vs. 26 years). Median TTCTH was double without dedicated FTA (median 50 vs. 26 minutes, p < 0.001), despite similar justifiable delays (53% NTTR, 52% FTA). Without FTA, most delays (69%) were for emergency intubation. TTCTH after securing the airway was longer for NTTR group (median 38 vs. 26 minutes, p =0.0013). Even with no requirements for ED interventions, TTCTH for FTA was less than half versus NTTR (25 vs. 61 minutes, p =0.0013). Multivariate regression analysis indicated age and FTA with an attending surgeon as significant predictors of TTCTH, although the majority of variability in TTCTH was not explained by these two variables (R² = 0.33). Conclusion Full trauma activations involving attending trauma surgeons were quicker at transferring serious head injury patients to CT. Patients with FTA were younger and more seriously injured. Discerning the reasons for delays to CT should be used to refine protocols aimed at minimizing unnecessary delays and enhancing workforce efficiency and clinical outcome.

A multicenter prospective analysis of pediatric trauma activation criteria routinely used in addition to the six criteria of the American College of Surgeons.

Abstract
BACKGROUND The American College of Surgeons has defined six minimum activation criteria (ACS-6) for the highest level of trauma activations at trauma centers. The verification criteria also allow for the inclusion of additional criteria at the institution's discretion. The purpose of this prospective multicenter study was to evaluate the ACS-6 as well as commonly used activation criteria to evaluate overtriage and undertriage rates for pediatric trauma team activation. METHODS Data were prospectively collected at nine pediatric trauma centers to examine 29 commonly used activation criteria. Patients meeting any of these criteria were evaluated for the use of high-level trauma resuscitation resources according to an expert consensus list. Patients requiring a resource but not meeting any activation criteria were included to evaluate undertriage rates. RESULTS During the 1-year study, a total of 656 patients were enrolled with a mean age of 8 years, a median Injury Severity Score of 14, and mortality of 11%. Using all criteria, 55% of patients would have been overtriaged and 9% would have been undertriaged. If only the ACS-6 were used, 24% of patients would have been overtriaged and 16% would have been undertriaged. Among activation criteria with more than 10 patients, those most predictive of using a high-level resource were a gunshot wound to the abdomen (92%), blood given before arrival (83%), traumatic arrest (83%), tachycardia/poor perfusion (83%), and age-appropriate hypotension (77%). The addition of tachycardia/poor perfusion and pretrauma center resuscitation with greater than 40 mL/kg results in eight criteria with an overtriage of 39% and an undertriage of 10.5%. CONCLUSION The ACS-6 provides a reliable overtriage or undertriage rate for pediatric patients. The inclusion of two additional criteria can further improve these rates while maintianing a simplified triage list for children.

Abstract
OBJECTIVE Efficient triage may have a major influence on mortality and morbidity as well as financial consequences. A continuous effort to improve this decision making process and update the trauma alert criteria is being made. However, criteria for determining the evacuation priority are not well developed. We performed a prospective study to evaluate which pre-hospital parameters identify major trauma victims with an emphasis on a need for emergent surgical procedures. METHODS A prospective cohort included 601 patients admitted to a level one trauma centre over a three months period. The pre-hospital trauma alert criteria were recorded and set as independent variables. All major surgical procedures were graded in real time as: emergent, urgent, or not urgent. The ISS was calculated after completion of all the diagnostic workup. Patients were classified as major trauma victims if their calculated ISS was 16 or greater, and those needed an urgent intervention or intensive care. The relative risks (RR) for major trauma and a need for an emergent operation were calculated. RESULTS 243 (40%) patients were classified as having a major trauma. 39 (6.5%) patients required an emergent operative intervention: 24 for an active bleeding, 5 for a pericardial tamponade and 10 for an imminent cerebral herniation. Paramedic judgement and a penetrating injury to the trunk were the most common causes for over triage. However, a penetrating injury to the trunk had been the only clue that the victim needed an emergent operation in five cases. 128 patients had a pre-hospital Glasgow coma score (GCS) ≤ 12. Altered mental status was the most common and a significant predictor of both major trauma (RR of 3.00 with a 95% confidence interval (CI) of 1.98-4.53) and a need for an emergent operation (RR, 95% CI: 4.43, 2.28-8.58). Also, a systolic blood pressure ≤ 90 mmHg was highly associated with an emergent operation (RR, 95% CI: 11.69, 5.85-23.36). CONCLUSION For determining the evacuation priority, we suggest a triage system based on three major criteria: mental status, hypotension and a penetrating injury to the trunk. Overall, the set of trauma alert criteria system can be further simplified and enable better utilisation of resources.

Abstract
The geriatric trauma patient poses unique challenges to the trauma surgeon due to occult injuries and occult hypoperfusion. We hypothesized that those elderly patients with significant injuries, who were not initially evaluated via trauma activation, would suffer worse outcomes. All cases of elderly (age ≥ 65) admitted to the trauma service from the years 2000 to 2010 were included. Our trauma activation system encompasses anatomic, physiologic, and mechanism of injury criteria. We defined patients as undertriaged (UT) if they had an ISS > 15 and did not undergo a trauma team activation, but had a regular workup by an emergency department physician and trauma team consultation. Factors that contributed to being UT in the emergency department were investigated by univariate and multivariate analysis. A total of 4534 elderly patients constitute this analysis, of which 15.1 per cent were UT. The UT patients were more likely to die, when adjusted for Revised Trauma Score, Glasgow Coma score, the occurrence of ≥1 complication, and whether the patient was on Coumadin. UT has a high risk of death in elderly patients. Trauma triage guidelines need to be better tailored to identify the high-risk geriatric trauma patient.

Abstract
There have been many advances in the resuscitation and early management of patients with severe injuries during the last decade. These have come about as a result of the reorganisation of civilian trauma services in countries such as Germany, Australia and the United States, where the development of trauma systems has allowed a concentration of expertise and research. The continuing conflicts in the Middle East have also generated a significant increase in expertise in the management of severe injuries, and soldiers now survive injuries that would have been fatal in previous wars. This military experience is being translated into civilian practice. The aim of this paper is to give orthopaedic surgeons a practical, evidence-based guide to the current management of patients with severe, multiple injuries. It must be emphasised that this depends upon the expertise, experience and facilities available within the local health-care system, and that the proposed guidelines will inevitably have to be adapted to suit the local resources.

Abstract
This review describes the various components of a trauma team, and emphasises its value as one of many parts of a trauma system. The evidence for the team is weak and based on expert opinion and experience. Nevertheless, the evidence that high quality trauma systems improve survival, and that a trauma team is a vital component of all such systems is compelling. There is no evidence that a particular component of the team is essential. The trauma team is likely to have most impact on patients with moderate severity of trauma and probability of survival.

Abstract
The purpose of the trauma team is to provide advanced simultaneous care from relevant specialists to the seriously injured trauma patient. When functioning well, the outcome of the trauma team performance should be greater than the sum of its parts. Trauma teams have been shown to reduce the time taken for resuscitation, as well as time to CT scan, to emergency department discharge and to the operating room. These benefits are demonstrated by improved survival rates, particularly for the most severely injured patients, both within and outside of dedicated trauma centres. In order to ensure the best possible performance of the team, the leadership skills of the trauma team leader are essential and their non-technical skills have been shown to be particularly important. Team performance can be enhanced through a process of audit and assessment of the workings of the team and the evidence currently available suggests that this is best facilitated through the process of video review of the trauma resuscitation. The use of human patient simulators to train and assess trauma teams is becoming more commonplace and this technique offers a safe environment for the future education of trauma team staff. Trauma teams are a key component of most programmes which set out to improve trauma care. This article reviews the background of trauma teams, the evidence for benefit and potential techniques of performance assessment. The review was written after a PubMed, Ovid, Athens, Cochrane and guideline literature review of English language articles on trauma teams and their performance and hand searching of references from the relevant searched articles.

Abstract
A two phase prospective study was carried out at a regional Level I trauma center over 1 year. Phase I involved collecting observational data to determine which trauma criteria could potentially be used to identify patients that could be evaluated by a lower level trauma activation (category-3). A category-3 involved a smaller response team with priority access to imaging. Phase II involved implementing this third tier activation system and prospectively evaluating the outcomes related to resources and patient care. A total of 3104 patients were evaluated with 2076 patients in phase I and 1037 in phase II. Three commonly identified activation criteria out of the 36 studied were not associated with admission. These criteria were pedestrian struck by vehicle, high speed vehicular crash, and Glasgow Coma Score 12-14. These criteria were then used as triggers for a category-3 activation in phase II. Comparisons of patients with these three identified criteria between phase I and II demonstrated that significantly fewer patients were admitted, charges were reduced, emergency department times were similar, and less man-power hours were needed in phase II. The utilization of a third tiered activation system resulted in a decrease utilization of many resources without sacrificing patient care.

Abstract
BACKGROUND The pre-hospital assessment of a blunt trauma is difficult. Common triage tools are the mechanism of injury (MOI), vital signs, and anatomic injury (AI). Compared to the other tools, the clinical assessment of anatomic injury is more subjective than the others, and, hence, more dependent on the skills of the personnel.The aim of the study was to estimate whether the training and qualifications of the personnel are associated with the accuracy of prediction of anatomic injury and the completion of pre-hospital procedures indicated by local guidelines. METHODS Adult trauma patients met by a trauma team at Helsinki University Trauma Centre during a 12-month period (n = 422) were retrospectively analysed. To evaluate the accuracy of prediction of anatomic injury, clinically assessed pre-hospital injuries in six body regions were compared to injuries assessed at hospital in two patient groups, the patients treated by pre-hospital physicians (group 1, n = 230) and those treated by paramedics (group 2, n = 190). RESULTS The groups were comparable in respect to age, sex, and MOI, but the patients treated by physicians were more severely injured than those treated by paramedics [ISS median (interquartile range) 16 (6-26) vs. 6 (2-10)], thus rendering direct comparison of the groups ineligible. The positive predictive values (95% confidence interval) of assessed injury were highest in head injury [0,91 (0,84-0,95) in group 1 and 0,86 (0,77-0,92) in group 2]. The negative predictive values were highest in abdominal injury [0,85 (0,79-0,89) in group 1 and 0,90 (0,84-0,93) in group 2]. The measurements of agreement between injuries assessed pre- and in-hospitally were moderate in thoracic and extremity injuries. Substantial kappa values (95% confidence interval) were achieved in head injury, 0,67 (0,57-0,77) in group 1 and 0,63 (0,52-0,74) in group 2. The rate of performing the pre-hospital procedures as indicated by the local instructions was 95-99%, except for decompression of tension pneumothorax. CONCLUSION Accurate prediction of anatomic injury is challenging. No conclusive differences were seen in the ability of pre-hospital physicians and paramedics to predict anatomic injury in the respective patient populations.

Abstract
INTRODUCTION Pediatric surgeon-directed trauma teams (STTs) provide lifesaving treatment but at a high cost. We used physiologically based criteria to improve STT utilization. METHODS We reviewed 152 consecutive STT activations at one center, comparing standard and physiologically focused criteria and 24-hour hospital costs/charges for overtriaged patients vs level 2 (emergency department managed) blunt trauma patients matched for age, Injury Severity Score (ISS), and necessity for operation. RESULTS Our cohort (73.0% male; 86.8% blunt; median age, 8.0 [interquartile range, 4.0-14.0] years) had 10 deaths (6.6%) and 18 (11.8%) emergent operations. Twenty-nine patients met neither standard nor physiologic criteria (group 1), 25 met standard but not physiologic criteria (overtriaged, group 2), and 98 met physiologic criteria (group 3). Group 3 had higher median ISS (19.0 [10.0-33.0] vs 10.0 [4.0-17.0] and 5.5 [5.0-16.75] for groups 1 and 2, P = .001), more intensive care unit admissions (67.2% vs 31.0% and 52.0%, P = .001), longer hospitalization (5.0 [3.0-9.25] days vs 3.0 [1.0-5.0] and 4.0 [2.0-5.0] days, P = .002), and all patients who died or required emergent operation (P < .001). Physiologic criteria maintained 100% sensitivity but improved specificity (49.2% vs 23.0%). Overtriaged patients (n = 18) had 78.2% higher charges ($4700; 95% confidence interval, 13.3%-180.1%; P = .013) and 53.4% higher costs ($800; 95% confidence interval, 1.8%-131.2%; P = .041) than level 2 patients (n = 259) after adjusting for age, ISS, and need for operation, largely because of computed tomography and emergency department charges (66% of overtriaged charges). CONCLUSIONS Physiologic STT activation criteria would have saved 25 activations, $20,000 in costs, and $120,000 in charges annually without compromising patient safety.

Abstract
Hypotension is a trauma activation criterion validated by multiple studies. However, field systolic blood pressures (SBP) are still met with skepticism. How significant is the role of prehospital (PH) and emergency department (ED) SBP in the patient's overall condition? A review of the trauma registry over a 5-year period was conducted. PH SBPs were stratified into four categories: severe (SBP 80 mmHg or less), moderate (81-100 mmHg), mild hypotension (101-120 mmHg), and normotension (greater than 120 mmHg). These four groups were further subcategorized into the patients who were hypotensive, SBP 90 mmHg or less in the ED, versus those that were not (SBP greater than 90 mmHg). Data for 6964 patients were analyzed. Patients with PH SBP of 80 mmHg or less compared with patients who had PH SBP of greater than 80 mmHg had higher mortality (OR, 9; 95% CI, 6.45-12.84). Patients with both PH SBP 80 mmHg or less and ED SBP 90 mmHg or less had the highest risk of mortality (50%) and highest need for emergent operative intervention (54%). PH and ED hypotension is a strong predictor of in-hospital mortality and need for emergent surgical intervention in trauma patients. Field or ED blood pressures should serve as a significant marker of the patient's condition.
