Importance: Short- and long-term functional impairment after pediatric injury may be more sensitive for measuring quality of care compared with mortality alone. The characteristics of injured children and adolescents who are at the highest risk for functional impairment are unknown., Objective: To evaluate categories of injuries associated with higher prevalence of impaired functional status at hospital discharge among children and adolescents and to estimate the number of those with injuries in these categories who received treatment at pediatric trauma centers., Design, Setting, and Participants: This prospective cohort study (Assessment of Functional Outcomes and Health-Related Quality of Life After Pediatric Trauma) included children and adolescents younger than 15 years who were hospitalized with at least 1 serious injury at 1 of 7 level 1 pediatric trauma centers from March 2018 to February 2020., Exposure: At least 1 serious injury (Abbreviated Injury Scale score, ≥3 [scores range from 1 to 6, with higher scores indicating more severe injury]) classified into 9 categories based on the body region injured and the presence of a severe traumatic brain injury (Glasgow Coma Scale score <9 or Glasgow Coma Scale motor score <5)., Main Outcomes and Measures: New domain morbidity defined as a 2 points or more change in any of 6 domains (mental status, sensory, communication, motor function, feeding, and respiratory) measured using the Functional Status Scale (FSS) (scores range from 1 [normal] to 5 [very severe dysfunction] for each domain) in each injury category at hospital discharge. The estimated prevalence of impairment associated with each injury category was assessed in the population of seriously injured children and adolescents treated at participating sites., Results: This study included a sample of 427 injured children and adolescents (271 [63.5%] male; median age, 7.2 years [interquartile range, 2.5-11.7 years]), 74 (17.3%) of whom had new FSS domain morbidity at discharge. The proportion of new FSS domain morbidity was highest among those with multiple injured body regions and severe head injury (20 of 24 [83.3%]) and lowest among those with an isolated head injury of mild or moderate severity (1 of 84 [1.2%]). After adjusting for oversampling of specific injuries in the study sample, 749 of 5195 seriously injured children and adolescents (14.4%) were estimated to have functional impairment at hospital discharge. Children and adolescents with extremity injuries (302 of 749 [40.3%]) and those with severe traumatic brain injuries (258 of 749 [34.4%]) comprised the largest proportions of those estimated to have impairment at discharge., Conclusions and Relevance: In this cohort study, most injured children and adolescents returned to baseline functional status by hospital discharge. These findings suggest that functional status assessments can be limited to cohorts of injured children and adolescents at the highest risk for impairment.

Background: The Abbreviated Injury Scale (AIS) and Injury Severity Score (ISS) are widely used to assess trauma patients. In this study, the interobserver variability of the injury severity assessment for severely injured patients was analyzed based on different injured anatomical regions, and the various demographic backgrounds of the observers., Methods: A standardized questionnaire was presented to surgical experts and participants of clinical polytrauma courses. It contained medical information and initial X-rays/CT-scans of 10 cases of severely injured patients. Participants estimated the severity of each injury based on the AIS. Interobserver variability for the AIS, ISS, and New Injury Severity Score (NISS) was calculated by employing the statistical method of Krippendorff's α coefficient., Results: Overall, 54 participants were included. The major contributing medical specialties were orthopedic trauma surgery (N = 36, 67%) and general surgery (N = 13, 24%). The measured interobserver variability in the assessment of the overall injury severity was high (α ISS : 0.33 / α NISS : 0.23). Moreover, there were differences in the interobserver variability of the maximum AIS (MAIS) depending on the anatomical region: α head and neck : 0.06, α thorax : 0.45, α abdomen : 0.27 and α extremities : 0.55., Conclusions: Interobserver agreement concerning injury severity assessment appears to be low among clinicians. We also noted marked differences in variability according to injury anatomy. The study shows that the assessment of injury severity is also highly variable between experts in the field. This implies the need for appropriate education to improve the accuracy of trauma evaluation in the respective trauma registries.

The multiple ligament injured knee is a complex problem in orthopedic surgery. These injuries may or may not present as acute knee dislocations, and careful assessment of the extremity vascular and neurological status is essential because of the possibility of arterial and/or venous compromise, and nerve injury. These complex injuries require a systematic approach to evaluation and treatment. Physical examination and imaging studies enable the surgeon to make a correct diagnosis and formulate a treatment plan. Knee stability is improved postoperatively when evaluated with knee ligament rating scales, arthrometer testing, and stress radiographic analysis. Surgical timing depends upon the injured ligaments, vascular status of the extremity, reduction stability, and the overall health of the patient. The use of allograft tissue is preferred because of the strength of these large grafts, and the absence of donor site morbidity.

Purpose: The AIS scale is a measurement tool for single injuries. The ISS is considered the gold standard for determining the severity of injured patients, and the NISS was developed to improve the ISS with respect to loss of information, as well as to facilitate its calculation. The aim of this study was to analyse what injury severity measure, calculated according to the Abbreviated Injury Scale (AIS), 1998 and 2005 (update 2008) versions, performs better with mortality, cost and hospital length of stay healthcare indicators., Methods: This cross-sectional observational study was carried out between February 1st 2012 and February 1st 2013. Inclusion criteria were injured patients due to external causes admitted to trauma service through the emergency department. Manual coding of all injuries was performed and ISS and NISS scores were calculated for both versions of the AIS scale. Severity was then compared to mortality (in-hospital and at 30 days), healthcare cost, and length of hospital stay., Results: The index with the best predictive capability for in-hospital mortality was NISS 05 (AUC = 0.811). There was a significant increase in hospital stay and healthcare cost in the most severe patients in all indexes, except for ISS 05., Conclusions: NISS is found to be an index with higher predictive capability for in-hospital mortality and correlates better to length of hospital stay and healthcare cost.

Importance: The nasal bone is one of the most commonly fractured bones of the midface. However, the frequency of coincident fractures of adjacent bones such as the frontal process of the maxillary bone, nasal septum, and medial or inferior orbital walls has not been fully evaluated. Objective: The purpose of this study was to investigate the incidence of fractures of adjacent structures in the setting of a nasal bone fracture. Second, we propose a new classification system of nasal bone fractures with involvement of adjacent bony structures. Design, Setting, and Participants: One thousand, one hundred ninety-three patients with midfacial fractures were retrospectively reviewed. The characteristics of fractures of the nasal bone and the incidence of coincident fractures of the frontal process of maxilla, bony nasal septum, medial, or inferior orbital walls were analyzed. Exposure: All patients included in the study presented with nasal trauma. Main Outcomes and Measures: The coincident fractures of adjacent midfacial structures were assessed, and a new classification of midfacial fractures based on computed tomography (CT) scan images was proposed. Results: Among the 1193 cases, bilateral fractures of the nasal bone were most common (69.24%), and coexistent fracture of the frontal process of the maxilla and bony nasal septum was 66.89% and 42.25%, respectively. Coincident fracture of the orbital walls was observed in 16.51% of cases. The major etiology of fracture for the younger and elderly groups was falls, compared with assault as the most common etiology in the adult group. A classification scheme was generated in which fractures of the nasal bone were divided into five types depending on coexisting fractures of adjacent structures. Conclusions and Relevance: External force applied to the nasal bone can also lead to coexistent fracture of adjacent bony structures including the frontal process of the maxilla, nasal septum, and orbital walls. The proposed classification of nasal fracture based on CT imaging helps to incorporate coincident disruption of adjacent structures.

Injury is a leading cause of morbidity and mortality in the paediatric population and exhibits complex injury patterns. This study aimed to identify homogeneous groups of paediatric major trauma patients based on their profile of injury for use in mortality and functional outcomes risk-adjusted models. Data were extracted from the population-based Victorian State Trauma Registry for patients aged 0-15 years, injured 2006-2016. Four Latent Class Analysis (LCA) models with/without covariates of age/sex tested up to six possible latent classes. Five risk-adjusted models of in-hospital mortality and 6-month functional outcomes incorporated a combination of Injury Severity Score (ISS), New ISS (NISS), and LCA classes. LCA models replicated the best log-likelihood and entropy > 0.8 for all models (N = 1281). Four latent injury classes were identified: isolated head; isolated abdominal organ; multi-trauma injuries, and other injuries. The best models, in terms of goodness of fit statistics and model diagnostics, included the LCA classes and NISS. The identification of isolated head, isolated abdominal, multi-trauma and other injuries as key latent paediatric injury classes highlights areas for emphasis in planning prevention initiatives and paediatric trauma system development. Future risk-adjusted paediatric injury models that include these injury classes with the NISS when evaluating mortality and functional outcomes is recommended.

Background: Data accuracy is essential to obtaining correct results and making appropriate conclusions in outcomes research. Few have examined the quality of data that is used in studies involving orthopedic surgery. A nonspecific data entry has the potential to affect the results of a study or the ability to appropriately risk adjust for treatments and outcomes. This study evaluated the proportion of Not Further Specified (NFS) orthopedic injury codes found into two large trauma registries., Materials: Data from the National Trauma Data Bank (NTDB) from 2011 to 2015 and from the Michigan Trauma Quality Improvement Program (MTQIP) 2011-2017 were used. We selected multiple orthopedic injuries classified via the Abbreviated Injury Scale, version 2005 (AIS2005) and calculated the percentage of NFS entries for each specific injury., Results: There were a substantial proportion of fractures classified as NFS in each registry, 18.5% (range 2.4%-67.9%) in MTQIP and 27% (range 6.0%-68.5%) in the NTDB. There were significantly more NFS entries when the fractures were complex versus simple in both MTQIP (34.5% versus 9.6%, P < 0.001) and the NTDB (41.8% versus 15.7%, P < 0.001). The level of trauma center affected the proportion of NFS codes differently between the registries., Conclusions: The proportion of nonspecific entries in these two large trauma registries is concerning. These data can affect the results and conclusions from research studies as well as impact our ability to truly risk adjust for treatments and outcomes. Further studies should explore the reasons for these findings., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Study Objective: The latest wave of terrorism worldwide has seen significant use by terrorists of mundane, "low-technology" weapons, such as utility knives and civilian vehicles. How do the injuries they produce compare with that of more conventional terrorism mechanisms, such as use of firearms and explosives? We compare injury patterns of the most frequent terrorism-related injury mechanisms in an Israeli data set., Methods: This was a retrospective study of 1,858 patients hospitalized because of terrorism events, which were recorded in the Israeli National Trauma Registry between January 1997 and December 2016. The events were divided into 4 groups based on weapon used: explosions, shootings, stabbings, and vehicular attacks. The groups were compared in terms of injuries sustained, use of hospital resources, and clinical outcomes., Results: Explosion-related and vehicular terrorism resulted in a higher proportion of multiple injuries, whereas stabbings and shootings mostly led to isolated injuries. Victims of vehicular attacks had a high proportion of severe head injuries, whereas stabbing victims had a high volume of vascular injuries. All mechanisms involved significant damage to extremities; however, among stabbing victims injury was mainly to the upper extremities, whereas among vehicular attack victims it was mostly to the lower extremities. The overall injury severity of the compared groups was similar, leading to comparable levels of intensive care use and inhospital mortality. Certain similarities in victims' characteristics were observed between the shootings and stabbings and between explosions and vehicular attacks., Conclusion: Despite differences between various terrorist attack mechanisms, the resulting injury severity and inhospital mortality are very similar, with stabbings and vehicular attacks causing injuries as serious as those caused by conventional weapons., (Copyright © 2019 American College of Emergency Physicians.

Background: According to recently published findings, levels of the soluble receptor of advanced glycation end products (sRAGE) and its clearance from the blood may reflect the evolution of lung damage during hospitalization. Thus, the objective of this study was to reveal the course of sRAGE levels over the first three posttraumatic weeks, focusing on the severity of thoracic trauma and the development of acute respiratory distress syndrome (ARDS) and/or pneumonia., Methods: Twenty-eight consecutive surviving polytraumatized patients suffering thoracic trauma, age ≥ 18 years, Injury Severity Score ≥ 16, and directly admitted to our level I trauma center were enrolled in this prospective study. Blood samples were taken initially and on days 1, 3, 5, 7, 10, 14, and 21 during hospitalization. Luminex multi-analyte-technology was used for biomarker analysis., Results: Common to all our patients was an almost continuous decline of sRAGE levels within the first five posttraumatic days. Day 0 levels in polytrauma victims with severe thoracic trauma were more than twice as high than in those suffering mild thoracic trauma ( p  = 0.035), whereas the difference between the two groups did not reach significance from day 1. Neither the development of ARDS and/or pneumonia nor the necessity of secondary surgery did result in significant differences in sRAGE levels between the subgroups with and without the particular complication at any time point., Conclusions: sRAGE levels assessed immediately after hospital admission might serve as a diagnostic marker for the vehemence of impacts against the chest and thus might be applied as an additional tool in diagnosis, risk evaluation, and choice of the appropriate treatment strategy of polytraumatized patients in routine clinical practice., Competing Interests: The study was approved by the Ethics Committee of the Medical University of Vienna.

Fractures of the scapula are rare and have an incidence of 1% of all fractures. Publications highlight glenoid rim fractures. Classification by Ideberg and Euler and Rüdi are accepted. Euler and Rüdi describe three extra-articular and two intra-articular fracture patterns. The indications for surgery are displaced glenoid fractures, scapula tilt of more than 40° and injuries to the superior shoulder suspensory complex. We describe a case of a 22 year old man, who while cycling collided with a moving car due to wet roads. After his admission to hospital as a polytraumatised patient, the trauma CT-Scan showed haemothorax with several associated rip fractures, displaced humeral shaft fracture and fractures of the acromion and glenoid, classified as type D2c according to Euler and Rüdi. Following damage control principles, drainage of the haemothorax was already performed in the ER and surgical treatment of the displaced humeral shaft fracture was performed on the day of admission. No peripheral neurological deficits were evident. After pulmonary stabilisation, surgery was performed 6 days later on the glenoid and acromion fracture, which in conjunction may be regarded as an injury to the superior shoulder suspensory complex. We performed an arthroscopically-assisted screw fixation of the glenoid fracture (type D2c according to Euler and Rüdi) and an ORIF procedure at the acromion. Postoperative rehabilitation was performed with passive abduction and elevation up to 90° for the first two weeks and active abduction an elevation up to 90° for weeks 3 to 6. Full ROM was allowed at week 7., Conclusion: Articular fractures of the glenoid are rare and mainly seen as rim fractures. The indications for surgery are displaced articular fractures and injury to the superior shoulder suspensory complex. As demonstrated by this article, type D2c fractures according to Euler and Rüdi can be treated effectively as an arthroscopically-assisted screw fixation procedure., Competing Interests: Die Autoren geben an, dass kein Interessenkonflikt besteht., (Georg Thieme Verlag KG Stuttgart · New York.)

Introduction: Many publications, mainly from other countries, suggest that the treatment of seriously injured children might be better in specialised paediatric trauma centres than in general trauma centres. Data from Germany are not available yet, but those from abroad were used for the recommendations made by the German Association for Trauma Surgery (DGU) on the topic of paediatric trauma in the "White Paper on Trauma Care". The goal of this study was to analyse whether the outcome of severely injured children is dependent on treatment level and on the availability of a paediatric surgeon based on the given data., Materials and Methods: Data from the "TraumaRegister DGU" between 2002 and 2012 were used. Children aged 1-15 years treated during the period 2002-2012 were included. Severity had to reach a minimum Injury Severity Score (ISS) of 9 and the treatment had to involve a stay at an Intensive Care Unit. Patients with an ISS ≥9 who died were also included to take into consideration children with particularly severe injuries., Results: Hospitals without a paediatric surgeon transferred the patients significantly more frequently (p < 0.001). Mean hospital stay was shorter in centres with a paediatric surgeon, with slightly longer median stays at an Intensive Care Unit. Hospitals without a paediatric surgeon performed slightly more frequent surgical interventions on injured children (barely significant at p = 0.045). The death rate and the calculated Revised Injury Severity Classification (RISC) II prognosis were the same with or without the presence of a paediatric surgeon. No difference was found in the Glasgow Outcome Score (GOS) between the group with and the group without involvement of a paediatric surgeon., Discussion: Overall, the medical care of seriously injured and polytraumatised children in Germany is good at all levels of treatment whether a paediatric surgeon is involved or not.

Background: Resource allocation to hospitals is highly dependent on appropriate case coding. For trauma victims, the major diagnosis-coding category (DCC) is multiple trauma (DCC26), which triggers higher funding. We hypothesized that DCC26 has limited capacity for appropriate identification of severe trauma victims., Methods: We studied Injury Severity Score (ISS), Trauma Related Injury Severity Score (TRISS) and in-hospital mortality using data recorded in three level 1 trauma centers over a 2-year period. Patients were divided into two groups: DCC26 and non-DCC26. For non-DCC26 patients, two subgroups were identified: patients with severe head trauma and patients with spinal trauma. Clinical endpoints were mortality, ISS>15 and TRISS, IGS II. Use of hospital resources was estimated using funding and expenditures associated with each patient., Results: During the study period, 2570 trauma victims were included in the analysis. These patients were 39±18 years old, with median ISS=14, and observed mortality=10 %. Group DCC26 had 811 (31 %) patients, group non-DCC26 1855 (69 %) patients. DCC26 coding identified a more severely injured group of patients. However, in the group non-DCC26, there was a high proportion of severe trauma (ISS>15: 35 %; TRISS<0.95: 9 %)., Conclusion: DCC26 is not an appropriate coding for severe trauma patients. For these patients, expenditures will include intensive care and rare and costly resources. We propose to take into account the TRISS score to improve trauma coding., (Copyright © 2017 Elsevier Masson SAS. All rights reserved.)

Background: The American Society of Anesthesiologists (ASA) physical status (PS) classification system assesses the preoperative health of patients. Previous studies demonstrated poor interrater reliability and variable ASA PS scores, especially in trauma scenarios. There are few studies that evaluated the assignment of ASA PS scores in trauma patients and no studies that evaluated ASA PS assignment in severely injured adult polytrauma patients. Our objective was to assess interrater reliability and identify sources of discrepancy among anesthesiologists and trauma surgeons in designating ASA PS scores to adult polytrauma patients., Methods: A link to an online survey containing questions assessing attitudes regarding ASA PS classification, demographic information, and 8 fictional trauma cases was e-mailed to anesthesiologists and trauma surgeons. The participants were asked to assign an ASA PS score to each scenario and explain their choice. Rater-versus-reference and interrater reliability, beyond that expected by chance, among respondents was analyzed using the Fleiss kappa analysis., Results: A total of 349 participants completed the survey. All 8 cases had inconsistent ASA PS scores; several cases had scores ranging from I to VI and variable emergency (E) designations. Using weighted kappa (Kw) analysis for a subset of 201 respondents (101 trauma surgeons [S] and 100 anesthesiologists [A]), we found moderate (Kw = 0.63; SE = 0.024; 95% confidence interval, 0.594-0.666; P < .001) interrater-versus-reference reliability. The interrater reliability was fair (Kw = 0.43; SE = 0.037; 95% confidence interval, 0.360-0.491; P < .001)., Conclusions: This study demonstrates fair interrater reliability beyond that expected by chance of the ASA PS scores among anesthesiologists and trauma surgeons when assessing adult polytrauma patients. Although the ASA PS is used in some trauma risk stratification models, discrepancies of ASA PS scores assigned to trauma cases exist. Future modifications of the ASA PS guidelines should aim to improve the interrater reliability of ASA PS scores in trauma patients. Further studies are warranted to determine the value of the ASA PS score as a trauma prognostic metric.

Objective: To evaluate the efficacy of using the Orthopaedic Trauma Association (OTA/AO) classification for both bone forearm fractures in predicting compartment syndrome., Design: Retrospective cohort., Setting: Level 1 Academic Trauma Center., Patients/participants: One hundred fifty-one patients 18 years of age and older, with both bone forearm fractures diagnosed from 2001 to 2016 were categorized based on the OTA/AO classification. Patients with both bone fractures caused by gunshot wounds were excluded., Main Outcome Measurements: The endpoint for our study was whether forearm fasciotomies were performed based on the presence of compartment syndrome., Results: Of a total of 151 both bone forearm fractures, 15% underwent fasciotomy. Six of 80 (7.5%) grouped 22-A3, 8 of 44 (18%) grouped 22-B3, and 9 of 27 (33%) grouped 22-C underwent fasciotomies for compartment syndrome (P = 0.004). The relative risks of developing compartment syndrome for group 22-B3 versus 22-A3 was 2.42 (P = 0.08), 22-C versus 22-B3 was 1.83 (P = 0.15), and 22-C versus 22-A3 was 4.44 (P = 0.002)., Conclusions: There is a significant correlation between the OTA/AO classification and the need for fasciotomies, with group C fractures representing the highest risk. Clinicians can use this information to have a higher index of suspicion for compartment syndrome based on OTA/AO classification to help minimize the risk of a missed diagnosis., Level of Evidence: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

The adequate treatment of severely injured patients is challenging and can only be successfully executed when it starts at the accident site and is continued in all treatment phases including the early rehabilitation phase. Treatment should be performed by an interdisciplinary team guided by a trauma surgeon in order to adequately manage the severe injuries some of which are life-threatening. Treatment of polytrauma patients is a key task of certified trauma centers and must follow standardized guidelines. For a successful therapy of severely injured patients lifetime training at regular intervals in well-established polytrauma concepts is a mandatory requirement., Competing Interests: Interessenkonflikt: Die Autoren geben an, dass keine Interessenkonflikte vorliegen., (Georg Thieme Verlag KG Stuttgart · New York.)

Potentially traumatizing events (PTE) are highly prevalent, and are associated with detrimental effects on psychological health, including increased risk of posttraumatic stress disorder (PTSD). Multiple endorsed PTEs (polytraumatization) may have even greater effects on a person's health than the impact of a single index event. To better understand patterns of polytraumatization, person-centered analytic techniques such as Latent class analysis (LCA) are recommended. The current study used LCA to explore latent subgroupings of people based on their endorsement of PTEs, thus defining patterns in PTE exposure. The sample included 850 participants who endorsed at least one PTE on a web-administered Trauma History Questionnaire (THQ). Results indicated a best-fitting 3-class solution: (1) a class with a greater probability of experiencing interpersonal PTEs and other PTEs, (2) a class with moderate PTE exposure and higher probability of mugging and accidents, and (3) a class with low PTE exposure. Differences in age, gender, and PTSD symptom severity accounted for class membership. Results suggest the experience of interpersonal PTEs may be a risk factor for additional lifetime PTE exposure, and is associated with increased PTSD severity. Additional findings underscore the heterogenity of trauma experiences, highlighting the importance of examining such patterns in future research., (Copyright © 2017. Published by Elsevier B.V.)

The new treatment procedures of the German Statutory Accident Insurance (DGUV) have ramifications for the injury type procedure clinics (VAV) from medical, economic and structural aspects. Whereas the latter can be assessed as positive, the medical and economical aspects are perceived as being negative. Problems arise from the partially unclear formulation of the injury type catalogue, which results in unpleasant negotiations with the occupational insurance associations with respect to financial remuneration for services rendered. Furthermore, the medical competence of the VAV clinics will be reduced by the preset specifications of the VAV catalogue, which opens up an additional field of tension between medical treatment, fulfillment of the obligatory training and acquisition of personnel as well as the continually increasing economic pressure. From the perspective of the author, the relinquence of medical competence imposed by the regulations of the new VAV catalogue is "throwing the baby out with the bathwater" because many VAV clinics nationwide also partially have competence in the severe injury type procedure (SAV). A concrete "competence-based approval" for the individual areas of the VAV procedure would be sensible and would maintain the comprehensive care of insured persons and also increase or strengthen the willingness of participating VAV hospitals for unconditional implementation of the new VAV procedure.

Background: The urine output is an important clinical parameter of renal function and blood volume status, especially in critically ill multiple trauma patients. In the present study, the minute-to-minute urine flow rate and its variability were analyzed in hypotensive multiple trauma patients during the first 6 h of their ICU (intensive care unit) stay. These parameters have not been previously reported., Methods: The study was retrospective and observational. Demographic and clinical data were extracted from the computerized Register Information Systems. A total of 59 patients were included in the study. The patients were divided into two study groups. Group 1 consisted of 29 multiple trauma patients whose systolic blood pressure was greater than 90 mmHg on admission to the ICU and who were consequently deemed to be hemodynamically compromised. Group 2 consisted of 30 patients whose systolic blood pressure was less than 90 mmHg on admission to the ICU and who were therefore regarded as hemodynamically uncompromised., Results: The urine output and urine flow rate variability during the first 6 h of the patients' ICU stay was significantly lower in group 2 than in group 1 ( p  < 0.001 and 0.006 respectively). Statistical analysis by the Pearson method demonstrated a strong direct correlation between decreased urine flow rate variability and decreased urine output per hour ( R  = 0.17; P  = 0.009), decreased mean arterial blood pressure ( R  = 0.24; p  = 0.001), and increased heart rate ( R  = 0.205; p  = 0.001)., Conclusion: These findings suggest that minute-to-minute urine flow rate variability is a reliable incipient marker of hypovolemia and that it should therefore take its place among the parameters used to monitor the hemodynamic status of critically ill multiple trauma patients.

Background: Prehospital trauma triage ensures proper transport of patients at risk of severe injury to hospitals with an appropriate corresponding level of trauma care. Incorrect triage results in undertriage and overtriage. The American College of Surgeons Committee on Trauma recommends an undertriage rate below 5% and an overtriage rate below 50% for prehospital trauma triage protocols. To find the most accurate prehospital trauma triage protocol, a clear overview of all currently available protocols and corresponding outcomes is necessary., Objectives: The aim of this systematic review was to evaluate the current literature on all available prehospital trauma triage protocols and determine accuracy of protocol-based triage quality in terms of sensitivity and specificity., Methods: A search of Pubmed, Embase, and Cochrane Library databases was performed to identify all studies describing prehospital trauma triage protocols before November 2016. The search terms included "trauma," "trauma center," or "trauma system" combined with "triage," "undertriage," or "overtriage." All studies describing protocol-based triage quality were reviewed. To assess the quality of these type of studies, a new critical appraisal tool was developed., Results: In this review, 21 articles were included with numbers of patients ranging from 130 to over 1 million. Significant predictors for severe injury were: vital signs, suspicion of certain anatomic injuries, mechanism of injury, and age. Sensitivity ranged from 10% to 100%; specificity from 9% to 100%. Nearly all protocols had a low sensitivity, thereby failing to identify severely injured patients. Additionally, the critical appraisal showed poor quality of the majority of included studies., Conclusion: This systematic review shows that nearly all protocols are incapable of identifying severely injured patients. Future studies of high methodological quality should be performed to improve prehospital trauma triage protocols., Level of Evidence: Systematic review, level III.

Although fracture type and treatment options for ankle fractures are well defined, the differences between mono- and polytrauma patients and low- and high-energy trauma have not been addressed. The aim of the present study was to compare the fracture type and trauma mechanism between mono- and polytrauma and low- and high-energy trauma patients with an ankle fracture. We performed a single-center retrospective cohort study. Fractures were classified according to the Lauge-Hansen classification and a descriptive classification. High-energy trauma (HET) was defined using triage criteria. All other patients were classified as having experienced low-energy trauma (LET). The patients were divided into 2 groups according to the injury severity score (ISS). Monotrauma patients were defined as patients with an ISS of 4 to 11 with an isolated ankle fracture or an ankle fracture with a minor contusion or laceration. Polytrauma patients were defined as patients with an ISS of ≥16 with ≥2 body regions involved. Patients with an ISS from 12 to 15 were excluded. A total of 96 patients were eligible for analysis. Of the 96 patients, 62 had experienced monotrauma and 34 had experienced polytrauma. A significant difference was found between the mono- and polytrauma patients in the Lauge-Hansen classification (p < .001). Monotrauma patients had a high incidence of an isolated supination external rotation injury. Supination adduction and pronation abduction injuries were more often observed in polytrauma patients. The same pattern was observed for ankle fractures after HET compared with LET (p < .001), because all pronation abduction and supination adduction injuries were observed after a HET mechanism. The results of the present study indicate that polytrauma patients sustain different types of ankle fractures than patients with an isolated ankle fracture. This difference likely results from the high-energy transfer associated with polytrauma, because pronation abduction and supination adduction injuries were only observed after HET., (Copyright © 2017 American College of Foot and Ankle Surgeons.

Objective: Data in trauma registries need to be reliable when used for evaluation of injury management, trauma protocols and hospital statistics. The aim of this audit was to analyse the reliability of the data in the Trauma Centre West Netherlands (TCWN) region., Design: Routinely registered trauma patients from all nine hospitals in the TCWN region were re-registered by a registrar for analysis., Setting: Nine hospitals in the TCWN region in the Netherlands., Participants: A randomly selected representative trauma population sample of 350 patients and a sample of 100 polytrauma patients were re-registered and used for analysis., Intervention: Re-registration of trauma patients in the Trauma Registry., Main Outcome Measure(s): The inter-rater agreement on Injury Severity Score (ISS), number of Abbreviated Injury Scale (AIS) codes, identical codes and survival status were analysed using Kappa's coefficient and intraclass correlation coefficients., Results: The inter-rater agreement on ISS and number of AIS codes were, respectively, almost perfect (ICC = 0.81) and substantial (ICC = 0.76) in the trauma population sample, and substantial (ICC = 0.70) and fair (ICC = 0.33) in the polytrauma sample. For patients with serious injuries (AIS ≥ 2) in the population sample, the inter-rater agreement on ISS (ICC = 0.87) and number of AIS codes (ICC = 0.84) were almost perfect., Conclusions: These results confirm that the Dutch regional registry system works well and may serve as a reliable basis for prospective analysis of national and international trauma care. Particular attention should be paid to the coding of polytrauma patients as discrepancies are more likely to occur in this group., (© The Author 2016.

Introduction: In the Lower-Middle Income Country setting, we validate trauma severity scoring systems, namely Injury Severity Score (ISS), New Injury Severity Scale (NISS) score, the Kampala Trauma Score (KTS), Revised Trauma Score (RTS) score and the TRauma Injury Severity Score (TRISS) using Indian trauma patients., Patients and Methods: From 1 September 2013 to 28 February 2015, we conducted a prospective multi-centre observational cohort study of trauma patients in four Indian university hospitals, in three megacities, Kolkata, Mumbai and Delhi. All adult patients presenting to the casualty department with a history of injury and who were admitted to inpatient care were included. The primary outcome was in-hospital mortality within 30-days of admission. The sensitivity and specificity of each score to predict inpatient mortality within 30days was assessed by the areas under the receiver operating characteristic curve (AUC). Model fit for the performance of individual scoring systems was accomplished by using the Akaike Information criterion (AIC)., Results: In a registry of 8791 adult trauma patients, we had a cohort of 7197 patients eligible for the study. 4091 (56.8%)patients had all five scores available and was the sample for a complete case analysis. Over a 30-day period, the scores (AUC) was TRISS (0.82), RTS (0.81), KTS (0.74), NISS (0.65) and ISS (0.62). RTS was the most parsimonious model with the lowest AIC score. Considering overall mortality, both physiologic scores (RTS, KTS) had better discrimination and goodness-of-fit than ISS or NISS. The ability of all Injury scores to predict early mortality (24h) was better than late mortality (30day)., Conclusion: On-admission physiological scores outperformed the more expensive anatomy-based ISS and NISS. The retrospective nature of ISS and TRISS score calculations and incomplete imaging in LMICs precludes its use in the casualty department of LMICs. They will remain useful for outcome comparison across trauma centres. Physiological scores like the RTS and KTS will be the practical score to use in casualty departments in the urban Indian setting, to predict early trauma mortality and improve triage., (Copyright © 2016 Elsevier Ltd.

Background: A broad range of systemic complications has been described to occur in patients with open major fractures. Various causes have been claimed to play a role. We therefore surveyed a nationwide trauma registry to assess risk factors associated with closed and various types of open femur fractures., Methods: This was a cohort study in a nationwide population-based prospective database. Inclusion criteria for selection from database are as follows: individuals with femur fracture, age 16 years or older, and survival until primary admission. Main groups included closed and open femur fracture. Patient demographics, injury severity (New Injury Severity Score), surgical fracture management, length of stay, and systemic complications (e.g., multiple organ failure [MOF], sepsis, mortality) were collected and statistically analyzed using SPSS statistics. Multivariate regression analysis was performed to stratify subgroups for the degree of open soft-tissue injury according to Gustilo and Anderson., Results: Among 32,582 documented trauma victims (January 1, 2002, to December 31, 2010), a total of 5,761 met the inclusion criteria. Main groups: 4,423 closed (76.8%) and 1,338 open femur fractures (23.2%). Open fractures subgroups were divided into I° (334, 28.1%), II° (526, 44.3%), and III° (328, 27.6%). Open fractures were associated with an increased risk of prehospital hemorrhagic shock (p = 0.01), higher resuscitation requirements (p < 0.001), MOF (p = 0.001), and longer in-hospital (p < 0.001) and intensive care stay (p = 0.001). While New Injury Severity Score values showed a minor increase per subgroup, the prevalence of MOF, sepsis, and mortality multiplied with the degree of open soft-tissue injury. Especially patients with Type III open femur fractures received mass transfusions (28.2%, p < 0.001), and mass transfusions were identified as independent predictor for sepsis (odds ratio [OR], 2.393; 95% confidence interval [CI], 1.821-3.143; p < 0.001) and MOF (OR, 2.966; 95% CI, 2.409-3.651; p < 0.001). Our data also indicate an increased mortality in patients with open femur managed outside Level I trauma centers (OR, 1.358; 95% CI, 1.018-1.812; p = 0.037)., Conclusion: Open femur fractures are associated with higher in-hospital complications related to incidence of MOF, associated intensive care unit stay, and hospital days when compared with closed femur fractures. For prevention of in-hospital complications, prompt hemorrhage control, surgical fracture fixation, cautious blood management, and triage to a Level I trauma center must be considered., Level of Evidence: Epidemiologic/prognostic study, level II.

Introduction: The introduction of major trauma centres (MTCs) in England has led to 63% reduction in trauma mortality.(1) The role of plastic surgeons supporting these centres has not been quantified previously. This study aimed to quantify plastic surgical workload at an urban MTC to determine the contribution of plastic surgeons to major trauma care., Methods: All Trauma Audit and Research Network (TARN)-recorded major trauma patients who presented to an urban MTC in 2013 and underwent an operation were identified retrospectively. Patients who underwent plastic surgery were identified and the type and date of procedure(s) were recorded. The trauma operative workload data of another tertiary surgical specialty and local historical plastics workload data from pre-MTC go-live were collected for comparison., Results: Of the 416 major trauma patients who required surgical intervention, 29% (n = 122) underwent plastic surgery. Of these patients, 43% had open lower limb fractures, necessitating plastic surgical involvement according to British Orthopaedic Association Standards for Trauma (BOAST) 4 guidance. The overall plastic surgery operative workload increased sevenfold post-MTC go-live. A similar proportion of the same cohort required neurosurgery (n = 115; p = 0.589)., Discussion: This study quantifies plastic surgery involvement in major trauma and demonstrates that plastic surgical operative workload is at least on par with other tertiary surgical specialties. It also reports one centre's experience of a significant change in plastic surgery activity following designation of MTC status. The quantity of plastic surgical operative workload in major trauma must be considered when planning major trauma service design and workforce provision, and for plastic surgical postgraduate training., (Copyright © 2016 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Background and Objectives: Trauma patients often suffer from persisting pain even years after injury, and data on long-term pain management is lacking. The aim of this study was to evaluate the frequency of persisting pain and health-related quality of life (HrQoL) among trauma victims 2 years after injury. Furthermore, the frequency of pain specialist consultation and the quality of outpatient pain management, including phamacological management, was assessed., Materials and Methods: We analyzed prospectively collected data on severely injured adult patients treated between 2008-2011 at the Cologne Merheim Medical Center (CMMC)/Germany.  Data included the 'Polytrauma Outcome Profile' and a standardized questionnaire on outpatient pain management. Exclusion criteria were death, inability to answer the questionnaire due to cognitive disabilities and lack of language knowledge., Results and Conclusions: 207/391 (53 %) data sets were available for analysis, presenting a typical trauma collective with injury severity of ISS 19, predominantly male and a mean age of 44 years. 2 years after trauma 59 % still reported that they suffered from severe persisting pain; 53 % of these patients were under pharmacological pain medication. Only 1/5 of the patients with severe persisting pain was treated by a pain specialist. Successful treatment options do exist; improvement of treatment is required.

Severe trauma is still one of the leading causes of death worldwide. The initial treatment and diagnostics are of immense importance in polytraumatized patients. The initial approach mainly focuses on the advanced trauma life support (ATLS) concept. This includes the identification of life-threatening conditions and application of life-saving interventions. Depending on the physiological condition of the patient, the surgical treatment strategies of early total care (ETC) or damage control orthopedics (DCO) can be chosen. Appropriate surgical management can reduce the incidence of associated delayed systemic complications. This review summarizes the most commonly used definitions of polytrauma (including the Berlin polytrauma definition) and classification systems of severely injured patients. Moreover, the recently introduced treatment strategy of the safe definitive surgery concept for severely injured patients is also discussed in this article.

Background: Dog bites are considered to be septic injuries, and their location on the face, with its highly symbolic topography and important social functions, is particularly pertinent. In addition to specific medical aspects, such as their psychological impact, they are also of relevance in terms of child protection measures. In light of the far-reaching importance of this subject, we were prompted to carry out a prospective study, over 13 years, to identify risk factors. Our results highlight specific risk factors, and they may hence assist with the implementation of concrete primary prevention measures against dog bites., Methods: An information sheet was prepared and filled out during the intake of patients who had been bitten on the face. Data analysis was performed using Epi Info Version 6.04dfr software to find a correlation between the factors studied and the dog bite to the face., Results: Dog bites to the face represented 0.83% of the emergency admissions to our service. A considerable majority of these involved children, with 68.5% of patients <16 years of age, and 33.3% of patients aged between 2 and 5 years. The wounds were multiple and of variable severity. The type of dog involved was frequently a German Shepherd. Strikingly, 91.3% of bites had occurred in a single-parent environment., Conclusions: Our study has determined that the fundamental factors that increase the probability of a dog bite to the face are as follows: the child being 2-5 years old, a single-parent context, and involvement of a German Shepherd-type dog., (Copyright © 2015 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Purpose: The broad spectrum of frontal bone fractures, including those with orbital and skull base extension, is poorly understood. We propose a novel classification scheme for frontal bone fractures., Methods: Maxillofacial CT scans of trauma patients were reviewed over a five year period, and frontal bone fractures were classified: Type 1: Frontal sinus fracture without vertical extension. Type 2: Vertical fracture through the orbit without frontal sinus involvement. Type 3: Vertical fracture through the frontal sinus without orbit involvement. Type 4: Vertical fracture through the frontal sinus and ipsilateral orbit. Type 5: Vertical fracture through the frontal sinus and contralateral or bilateral orbits. We also identified the depth of skull base extension, and performed a chart review to identify associated complications., Results: 149 frontal bone fractures, including 51 non-vertical frontal sinus (Type 1, 34.2%) and 98 vertical (Types 2-5, 65.8%) fractures were identified. Vertical fractures penetrated the middle or posterior cranial fossa significantly more often than non-vertical fractures (62.2 v. 15.7%, p = 0.0001) and had a significantly higher mortality rate (18.4 v. 0%, p < 0.05). Vertical fractures with frontal sinus and orbital extension, and fractures that penetrated the middle or posterior cranial fossa had the strongest association with intracranial injuries, optic neuropathy, disability, and death (p < 0.05)., Conclusions: Vertical frontal bone fractures carry a worse prognosis than frontal bone fractures without a vertical pattern. In addition, vertical fractures with extension into the frontal sinus and orbit, or with extension into the middle or posterior cranial fossa have the highest complication rate and mortality., (Copyright © 2015 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Trauma is one of the leading causes of death before the age of 40 years and approximately 5% of patients with trauma who require hospital admission have pelvic fractures. This article updates the emergency department classification of pelvic fractures first described in 2000. This information is of practical value to emergency physicians in identifying the potential vascular, genitourinary, gastrointestinal, orthopedic, and neurologic complications and further assists them in the initial evaluation and treatment of patients with pelvic fractures., (Copyright © 2015 Elsevier Inc.

Burns are classified according to the depth of the burn wound and extent of affected burned body surface area. In deep second degree and higher grade burns the epidermis and skin appendages are destroyed so that healing can only take place with severe scarring. In these cases necrectomy and skin grafting are recommended. Extensive and deep burns should be treated at specialized centers and more precise criteria for this are laid down in the guidelines. Emergency room treatment protocols have improved the quality of admission and treatment. Concomitant injuries need to be diagnosed and treated early. In addition to the damage to the skin the subsequent burn disease with massive accumulation of interstitial fluid determines the prognosis. The circulation is stabilized and the risk of infection is controlled by intensive fluid management, early necrectomy and split thickness skin grafting. Modern sedation and ventilation management allows a more rapid convalescence.

The present work deals primarily with the triage of injured victims after a mass casualty incident by emergency physicians. Triage is central for successful execution at the scene of a major accident. It ensures that the chaos is left at the scene of the accident and does not reach the hospitals. The enormous psychological burden for triage physicians is reflected and the delegation of activities to lay persons is critically examined. The work reflects the long-term experience of the authors.

Introduction: Multiple injured patients, polytrauma or severely injured patients are terms used as synonyms in international literature describing injured patients with a high risk of mortality and cost consuming therapeutic demands. In order to advance the definition of these terms, we analysed a large trauma registry. In detail, we compared critically ill trauma patients first specified on a pure anatomical base according to the ISS or NISS, second in the original "polytrauma definition" with two body regions affected and finally all of them combined with a physiological component., Patients and Methods: Records that were collected in the TraumaRegister DGU(®) of the German Trauma Society (Deutsche Gesellschaft für Unfallchirurgie, DGU) between 1993 and 2011 (92,479 patients) were considered for this study. All patients with primary admission from scene with a minimum hospital stay of 48 h and an Injury Severity Score (ISS)≥ 16 were included. Pre-hospital and early admission data were used to determine physiological risk factors and calculate individual risk of death using the Revised Injury Severity Classification (RISC)., Results: 45,350 patients met inclusion criteria. The overall hospital mortality rate was 20.4%. The predicted mortality according to the RISC-Score was 21.6%. 36,897 patients (81.4%) had injuries in several body regions. The prevalence of the five physiological risk factors varied between 17% (high age) and 34% (unconsciousness). There were 17,617 patients (38.8%) without any risk factor present on admission, while 30.6% (n=13,890) of the patients had one and 30.5% (n=13,843) had two or more factors present. Patients with ISS ≥ 16 but no physiological risk factor present had a very low mortality rate of 3.1% (542 of 17,617). With an increasing number of physiological factors there was an almost linear increase in mortality up to an 86% rate in patients with all five factors present. The 'polytrauma' definition of Butcher and colleagues with AIS ≥ 3 in at least two different body regions would apply to only 56.2% of patients in the present group with ISS ≥ 16. The mortality in this subgroup is only marginally higher (21.8%; 5559 of 25,494) than in the group of patients with only one severely affected body region (18.5%; 3675 of 19,875)., Conclusions: In our opinion the principle of sharpening an anatomically based definition by a defined physiological problem will help to specify the really critically ill trauma patients., (Copyright © 2014 Elsevier Ltd.

Introduction: A regionalized trauma system must be tailored to the trauma epidemiology and the trauma care resources of the population it serves. Pediatric trauma system in Singapore differs from others because of its geographic compactness and relatively low incidence of severe trauma. The scarcity of polytrauma highlights the need of a reliable screening system to identify injured children who necessitate urgent transport to emergency department (ED) with pediatric resuscitation capacity as well as activation of trauma team upon their arrival. In this study, the validity of Pediatric Trauma Score (PTS), Glasgow Come Scale (GCS), and respiratory rate (RR) in identifying pediatric patients with major trauma and receipt of resuscitation is evaluated., Patients and Methods: After obtaining Institutional Review Board approval, a retrospective analysis was performed using data obtained from our trauma registry between January 2011 and December 2012. Information pertaining to the demographics, causative mechanism, and injury description, resuscitation, admitting disciplines, surgical intervention, and outcome were analyzed. The sensitivity and specificity of PTS, GCS, and RR to predict outcomes of interest are calculated., Results: A total of 92 patients were recruited. From the 92 patients, 26 sustained major trauma, and 21 patients received ED resuscitation. The mean age was 4 years 9 months. Sensitivity and specificity of PTS ≤ 8, GCS ≤ 10, and abnormal RR for predicting major trauma were 61.5, 77.3; 26.9, 100; and 53.8, 60.6%; respectively. When the reliability to identify patients received ED resuscitation was evaluated the sensitivity and specificity of PTS ≤ 8, GCS ≤ 10, and abnormal RR were 90.5, 83.1; 28.6, 98.6; and 76.2, 66.2%; respectively., Conclusion: The parameters of PTS need to be further refined to improve its accuracy and minimize the undertriage rate. If a combined physiologic and anatomic scoring system such as PTS is used, other physiologic parameters such as GCS and RR may become redundant. The evaluation of the validity of PTS, GCS, and RR in predicting pediatric major trauma indicated poor reliability., (Georg Thieme Verlag KG Stuttgart · New York.)

Introduction: Winter sports have evolved from an upper class activity to a mass industry. Especially sledging regained popularity at the start of this century, with more and more winter sports resorts offering sledge runs. This study investigated the rates of sledging injuries over the last 13 years and analysed injury patterns specific for certain age groups, enabling us to make suggestions for preventive measures., Methods: We present a retrospective analysis of prospectively collected data. From 1996/1997 to 2008/2009, all patients involved in sledging injuries were recorded upon admission to a Level III trauma centre. Injuries were classified into body regions according to the Abbreviated Injury Scale (AIS). The Injury Severity Score (ISS) was calculated. Patients were stratified into 7 age groups. Associations between age and injured body region were tested using the chi-squared test. The slope of the linear regression with 95% confidence intervals was calculated for the proportion of patients with different injured body regions and winter season., Results: 4956 winter sports patients were recorded. 263 patients (5%) sustained sledging injuries. Sledging injury patients had a median age of 22 years (interquartile range [IQR] 14-38 years) and a median ISS of 4 (IQR 1-4). 136 (51.7%) were male. Injuries (AIS ≥ 2) were most frequent to the lower extremities (n=91, 51.7% of all AIS ≥ 2 injuries), followed by the upper extremities (n=48, 27.3%), the head (n=17, 9.7%), the spine (n=7, 4.0%). AIS ≥ 2 injuries to different body regions varied from season to season, with no significant trends (p>0.19). However, the number of patients admitted with AIS ≥ 2 injuries increased significantly over the seasons analysed (p=0.031), as did the number of patients with any kind of sledging injury (p=0.004). Mild head injuries were most frequent in the youngest age group (1-10 years old). Injuries to the lower extremities were more often seen in the age groups from 21 to 60 years (p<0.001)., Conclusion: Mild head trauma was mainly found in very young sledgers, and injuries to the lower extremities were more frequent in adults. In accordance with the current literature, we suggest that sledging should be performed in designated, obstacle-free areas that are specially prepared, and that children should always be supervised by adults. The effect of routine use of helmets and other protective devices needs further evaluation, but it seems evident that these should be obligatory on official runs., (Copyright © 2012 Elsevier Ltd.

Background: From the viewpoint of prehospital emergency medicine, a greater proportion of pelvic fractures not of a life-threatening status but combined with other injuries need more comprehensive recognition., Methods: A 12-year nationwide health database of inpatients was reviewed. All cases diagnosed as pelvic fractures were enrolled. The associated injuries classified into 20 categories were further analyzed., Results: During 2000-2011, the hospitalized incidence of pelvic fractures in Taiwan ranged from 17.17 to 19.42 per 100,000, and an increasing trend with age was observed. The mean case-fatality rate was 1.6% for females and 2.1% for males; male patients with pelvic fractures had a significantly higher risk of death than female patients after adjusting for other covariates. 74.2% of these cases were combined with other injuries. The most common associated injuries in an identified body region were other orthopedic fractures of the lower limbs (21.50%), spine/trunk (20.97%), or upper limbs (18.18%), followed by significant head injuries (17.59%), intra-abdominal injuries (11.00%), and thoracic injuries (7.20%)., Conclusion: The incidence of hospitalized pelvic fractures in Taiwan was low and the case-fatality rate was lower than those of other countries. Concurrently, coexistence of major combined injuries with pelvic fractures was easily treated at medical centers.

Background: 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., Methods: 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., Results: 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., Conclusions: 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.

Background: The current civilian Abbreviated Injury Scale (AIS), designed for automobile crash injuries, yields important information about civilian injuries. It has been recognized for some time, however, that both the AIS and AIS-based scores such as the Injury Severity Score (ISS) are inadequate for describing penetrating injuries, especially those sustained in combat. Existing injury coding systems do not adequately describe (they actually exclude) combat injuries such as the devastating multi-mechanistic injuries resulting from attacks with improvised explosive devices (IEDs)., Methods: After quantifying the inapplicability of current coding systems, the Military Combat Injury Scale (MCIS), which includes injury descriptors that accurately characterize combat anatomic injury, and the Military Functional Incapacity Scale (MFIS), which indicates immediate tactical functional impairment, were developed by a large tri-service military and civilian group of combat trauma subject-matter experts. Assignment of MCIS severity levels was based on urgency, level of care needed, and risk of death from each individual injury. The MFIS was developed based on the casualty's ability to shoot, move, and communicate, and comprises four levels ranging from "Able to continue mission" to "Lost to military." Separate functional impairments were identified for injuries aboard ship. Preliminary evaluation of MCIS discrimination, calibration, and casualty disposition was performed on 992 combat-injured patients using two modeling processes., Results: Based on combat casualty data, the MCIS is a new, simpler, comprehensive severity scale with 269 codes (vs. 1999 in AIS) that specifically characterize and distinguish the many unique injuries encountered in combat. The MCIS integrates with the MFIS, which associates immediate combat functional impairment with minor and moderate-severity injuries. Predictive validation on combat datasets shows improved performance over AIS-based tools in addition to improved face, construct, and content validity and coding inter-rater reliability. Thus, the MCIS has greater relevance, accuracy, and precision for many military-specific applications., Conclusion: Over a period of several years, the Military Combat Injury Scale and Military Functional Incapacity Scale were developed, tested and validated by teams of civilian and tri-service military expertise. MCIS shows significant promise in documenting the nature, severity and complexity of modern combat injury.

Current forms of medical reports cannot be used for clinical and epidemiological and medical and economic researches because they don't contain information about competitive, associated diseases and its complications. Authors developed the method of clinical and epidemiological monitoring of nosologic structure of patients in military-medical institutions based on personalized record-keeping of patients with additional informational resources for recording of all diagnoses and performed medical service. With the help of the given method were analyzed nosologic structure and treatment results of 548 patients with vehicular trauma from the 442nd District Military Clinical Hospital. Polytrauma was revealed in 22% of patients, concomitant injury--in 39%, combined injures--in 0.4%. Besides, in 8% of patients were revealed associated chronic diseases that not only confound trauma, but also make difficult to diagnose and assess the severity of trauma.

Pelvic injuries are often associated with multiple injuries of other body regions, neurovascular and visceral lesions, as well as hemodynamic instability. The use of a standardized classification characterizing the severity and stability of pelvic fractures and the early stabilization of pelvic ring injuries in appreciation of damage control principles has helped to improve the number of survivors. This is particularly necessary due to the higher number of older patients.Complex pelvic trauma still represents a life-threatening situation for the patient, particularly in multiple traumatized patients. Standardized clinical investigations and modern concepts even in the preclinical therapy of complex pelvic fractures make a contribution to enhancement of treatment options. Because of the still problematic long-term results after surgery of instable pelvic fractures, the need for modern treatment concepts has to be adapted to the requirements.

Trauma management in the emergency room is an important part of the treatment chain of the severely injured. Important decisions with respect to diagnostics and treatment must be made under time pressure. Successful trauma management in the emergency room requires a hospital tailored treatment protocol. This written protocol needs consent from all participating disciplines and must be known by all members of the resuscitation team. The ATLS® and the recently published clinical practice guidelines on multiple trauma can be of help in order to establish or update such protocols. In order to continuously evaluate and improve performance in the emergency room local quality circles are needed that truly follow that aim. Important factors are reliability of agreement between the different disciplines and continuous communication of results to the team members. In order to be successful such quality circles need people that care.

Background: The survival chances of multiple trauma patients have continually improved over the last decades; therefore, it is often not a question of whether a patient survives a severe accident but rather how the patient survives., Methods: In a retrospective study 127 patients were questioned regarding quality of life and health and possible influencing factors using the POLO chart an average of 70 months after suffering severe trauma (ISS Ø 35.6)., Results: The quality of life of severely injured patients is significantly reduced compared with the normal population even years after the trauma. In addition to four pretraumatic factors (older age, female gender, low education and previous illnesses) four posttraumatic variables (difficulties with authorities/institutions and unemployment as a consequence of the accident, long duration and subjectively inadequate treatment in hospital) were identified that have a negative impact on long-term quality of life., Conclusions: The self-reported quality of life after multiple trauma no longer permanently achieves the original level despite extensive rehabilitation measures. Post-traumatic factors have a greater impact on the long-term quality of life than the injury severity. A long-term care and specialized rehabilitation services are needed to improve outcome further.

Background: The TraumaNetwork DGU® (TNW) connects hospitals with different capacities for the treatment of severely injured patients who work together as superregional (STC), regional (RTC) and local trauma centres (LTC). The standards of treatment and equipment are defined on the basis of current guidelines as published in the"White book of the Treatment of Severely Injured Patients". An external audit process evaluates the organisation and structure of participating hospitals as well as the cooperation of the trauma centres within a regional TNW., Results: In May 2013 a total of 618 hospitals were visited and assessed according to the White book and 39 fully certified regional TNWs covered around 85% of the area of Germany. Treatment quality in the certified TCs was analyzed on the basis of 25,249 severely injured patients in the TraumaRegister DGU® (2008-2011) and significant differences between the expected and observed mortality rates were found. These differences were most obvious in superregional and regional trauma centres., Conclusion: The TraumaNetwork represents an innovative, cooperative project for successfully improving the treatment of severely injured patients.

The human face contains the sense organs and is responsible for essential functions: swallowing, chewing, speech, breathing and communication. It is also and most importantly the seat of a person's identity. Multiple trauma adds a life-threatening dimension to the physical and psychological impact of a facial trauma.

Treatment of patients with multiple trauma is known to require validated established algorithms, experienced medical staff and intensive interdisciplinary cooperation between the medical disciplines. In order to predict the risk for potential complications and mortality, adequate assessment of patients with multiple trauma is crucial for further treatment decisions. Therefore, different scoring systems have been developed to assess injury severity and to predict the potential outcome after multiple trauma. These scores have in common that the severity of trauma is converted to a numeric value simplifying the physiological reality in general. But the anatomic as well as physiological impact after multiple trauma can hardly be represented comprehensively by a single numeric value. Consequently, the established scores can only be safely interpreted, if the individual limitations of each scoring system are known.

Background: The major paediatric public health problem worldwide is injury or trauma. In 2004, 950 000 children died as a result of injury., Objective: The aim of this study was to evaluate the logistics of medical care after paediatric polytrauma within the first hours after arrival into a trauma unit - the so-called Golden Hour., Methods: Children presenting with polytrauma to the Trauma Unit at the Red Cross War Memorial Children's Hospital between May 2011 and August 2011 were considered for inclusion in the study., Results: Fifty-five children were included in the final analysis. The median duration of stay in the Trauma Unit was 205 minutes (interquartile range 135 - 274)., Conclusion: Several factors were identified that unnecessarily prolonged the time that patients stayed in the trauma unit following arrival in hospital for polytrauma management.

Purpose: The purpose of this study was to retrospectively investigate the aetiology, pattern, and treatment of mandibular condylar fractures in our department over the past 22 years., Patients and Methods: Data of patients who sustained mandibular condylar fractures from 1988 to 2009 were recorded, including fracture aetiology, pattern of condylar fracture, time, age, sex, associated injury, patient transferred by other clinics, lag time and treatment method. Data analysis included X(2) test, Fisher exact test, t-test, Ridit analysis and Logistic regression analysis., Results: The sample was composed of 549 patients (749 condylar fractures), 404 male and 145 female (male:female = 2.79:1), with a mean age of 30.12 ± 14.44 years. Road traffic accidents were the most common cause (248, 45.2%). Condylar head fractures were significantly related to a fall at ground level (p = .001). A fall from a height had a 3.19-fold risk of bilateral condylar fractures (odds ratio, 3.19; 95% confidence interval, 1.33 to 7.65; p = .010). A majority of the condylar fractures (693, 92.5%) were treated by a surgical procedure. Condylar head were mostly removed (95.0%, p < .001), condylar neck and condylar base fractures were most frequently treated by open reduction and internal fixation with miniplates (74.4%, p < .001). Most of the dislocated condylar fractures were treated by open surgery (96.5%, p = .026)., Conclusions: The anatomic position and uni/bilateral pattern of mandibular condylar fractures were positively related to situations when considerable force is involved. Open condylar surgery was based on the level of fracture and degree of displacement or dislocation., (Copyright © 2012 European Association for Cranio-Maxillo-Facial Surgery.

Accidents and trauma are the leading cause of hospital admissions and major contributors to mortality in children and adolescents. There are age-specific injury patterns and differences in the clinical presentation of pediatric trauma and treatment both at the scene and in the emergency department can be observed. In general, pediatric trauma-scores to appreciate injury severity are adapted from the adult population.The most important factor to increase mortality in the severely injured pediatric population is the extent of a concomitant traumatic brain injury (TBI). In addition, the acute trauma-associated coagulopathy, which is triggered multifactorial, is an independent prognostic marker for mortality in severe trauma. The complexity of all currently available trauma-scores for the pediatric population is one reason why these scores are not unequivocal recommended for the early use in pediatric trauma care. The pediatric BIG-Score was developed to allow an early prognostic stratification for pediatric trauma patients and includes with base excess (BE), INR (International Normalized Ratio) and GCS (Glasgow Coma Scale) relevant prognostic factors for poor outcome. Early risk stratification is crucial in pediatric trauma due to mortality rates ranging between 9% and 15% and with 50% of all fatalities to occur within the first 24 h of hospital admission., (© Georg Thieme Verlag KG Stuttgart · New York.)

Background: The systemic inflammatory response syndrome (SIRS) has been advocated as a significant predictor of outcome in trauma. Recent trauma literature has proposed SIRS as a surrogate for physiological derangements characteristic of polytrauma with some authors recommending its inclusion into the definition of polytrauma. The practicality of daily SIRS collection outside of specifically designed prospective trials is unknown. The purpose of this study was to assess the availability of SIRS variables and its appropriateness for inclusion into a definition of polytrauma. We hypothesised SIRS variables would be readily available and easy to collect, thus represent an appropriate inclusion into the definition of polytrauma., Method: A prospective observational study of all trauma team activation patients over 7-months (August 2009 to February 2010) at a University affiliated level-1 urban trauma centre. SIRS data (temperature>38°C or <36°C; Pulse >90 bpm; RR>20/min or a PaCO(2)<32 mmHg; WCC>12.0×10(9)L(-1), or <4.0×10(9)L(-1), or the presence of >10 immature bands) collected from presentation, at 24 h intervals until 72 h post injury. Inclusion criteria were all patients generating a trauma team activation response age >16., Results: 336 patients met inclusion criteria. In 46% (155/336) serial SIRS scores could not be calculated due to missing data. Lowest rates of missing data observed on admission [3% (11/336)]. Stratified by ISS>15 (132/336), in 7% (9/132) serial SIRS scores could not be calculated due to missing data. In 123 patients ISS>15 with complete data, 81% (100/123) developed SIRS. For Abbreviated Injury Scale (AIS)>2 in at least 2 body regions (64/336) in 5% (3/64) serial SIRS scores could not be calculated, with 92% (56/61) of patients with complete data developing SIRS. For Direct ICU admissions [25% (85/336)] 5% (4/85) of patients could not have serial SIRS calculated [mean ISS 15(±11)] and 90% (73/81) developed SIRS at least once over 72 h., Conclusion: Based on the experience of our level-1 trauma centre, the practicability of including SIRS into the definition of polytrauma as a surrogate for physiological derangement appears questionable even in prospective fashion., (Copyright © 2012 Elsevier Ltd.
