ABSTRACT
Purpose: The aim of the study was to evaluate how many patients are being transferred between trauma centers and and their characteristics in the 2006 initiated TraumaNetzwerk DGU® (TNW). We further investigated the time point of transfer and differences in outcome, compared to patients not being transferred. We wanted to know how trauma centers judged the performance of the TNW in transfer. Method: (1) We analyzed the data of the TraumaRegister DGU® (TR-DGU) from 2014-2018. Included were patients that were treated in German trauma centers, maximum AIS (MAIS) >2 and MAIS 2 only in case of admission on ICU or death of the patient. Patients being transferred were compared to patients who were not. Characteristics were compared, and a logistic regression analysis performed to identify predictive factors. (2) We performed a survey in the TNW focussing on frequency, timing and communication between hospitals and improvement through TNW. Results: Study I analyzed 143,195 patients from the TR-DGU. Their mean ISS was 17.8 points (SD 11.5). 56.4% were admitted primarily to a Level-I, 32.2% to a Level-II and 11.4% to a Level-III Trauma Center. 10,450 patients (7.9%) were transferred. 3,667 patients (22.7%) of the admitted patients of Level-III Center and 5,610 (12.6%) of Level-II Center were transferred, these patients showed a higher ISS (Level-III: 18.1 vs. 12.9; Level-II: 20.1 vs. 15.8) with more often a severe brain injury (AIS 3+) (Level-III: 43.6% vs. 13.1%; Level-II: 53.2% vs. 23.8%). Regression analysis showed ISS 25+ and severe brain injury AIS 3+ are predictive factors for patients needing a rapid transfer. Study II: 215 complete questionnaires (34%) of the 632 trauma centers. Transfers were executed within 2 h after the accident (Level-III: 55.3%; Level-II: 25.0%) and between 2-6 h (Level-III: 39.5%; Level-II: 51.3%). Most trauma centers judged that implementation of TNW improved trauma care significantly (Level III: 65.0%; Level-II: 61.4%, Level-I: 56.7%). Conclusion: The implementation of TNW has improved the communication and quality of comprehensive trauma care of severely injured patients within Germany. Transfer is mostly organized efficient. Predictors such as higher level of head injury reveal that preclinical algorithm present a potential of further improvement.
ABSTRACT
Adequate analgesia is one of the most important measures of emergency care in addition to treatment of vital function disorders and, if indicated, should be promptly undertaken; however, a large proportion of emergency patients receive no or only inadequate pain therapy. The numeric rating scale (NRS) is recommended for pain assessment but is not applicable to every group of patients; therefore, vital signs and body language should be included in the assessment. Pain therapy should reduce the NPRS to <5 points. Ketamine and fentanyl, which have an especially rapid onset of action, and also morphine are suitable for analgesia in spontaneously breathing patients. Basic prerequisites for safe and effective analgesia by healthcare professionals are the use of adequate monitoring, the provision of well-defined emergency equipment, and the mastery of emergency procedures. In a structured competence system, paramedics and nursing personnel can perform safe and effective analgesia.

PURPOSE: Reconstruction of the medial patellofemoral ligament (MPFL) has been established as standard of care for patellofemoral instability. An anatomic femoral tunnel position has been shown to be a prerequisite for restoration of patellofemoral stability and biomechanics. However, the incidence of malpositioning of the femoral tunnel during MPFL reconstruction continues to be notable. Palpation of anatomic landmarks and intraoperative fluoroscopy are the two primary techniques for tunnel placement. The aim of this study was to compare the accuracy of these two methods for femoral tunnel placement. METHODS: From 2016 to 2017, 64 consecutive patients undergoing MPFL reconstruction for patelllofemoral instability were prospectively enrolled. During surgery, the presumed femoral MPFL insertion was identified by both palpation of anatomic landmarks and using fluoroscopy, both of these points were separately documented on true lateral radiographs. They were then analysed and deviations from the Schoettle's Point were measured as anterior-posterior and proximal-distal deviations. A tunnel position within a radius of 7 mm around the Schoettle's Point was designated as an "accurate tunnel position". RESULTS: Compared to the method of palpation, fluoroscopy led to significantly more anatomic femoral tunnel positoning (p < 0.0001). The mean proximal-distal and anterior-posterior distances between the femoral insertion site identified by palpation and the Schoettle's Point were 5.7 ± 4.5 mm (0.3-20.3 mm) and 4.1 ± 3.7 mm (0.1-20.3 mm), respectively, versus 1.7 ± 0.9 mm (0.1-3.6 mm) and 1.8 ± 1.3 mm (0.1-4.8 mm) for fluoroscopy, respectively. Using fluoroscopy, all femoral insertion sites were identified within a 7 mm radius around the centre of the Schoettle's Point. In contrast, only 52% (33) of femoral insertion sites identified by palpation were within this radius. These data were independent of patients' age, gender and BMI. No improvement in accuracy of femoral tunnel positions was detected over time. CONCLUSIONS: The main finding of this study was that, compared to the method of palpation of anatomic landmarks, the use of intraoperative fluoroscopy in MPFL reconstruction leads to more accurate femoral tunnel positioning. Based on these results, the use of intraoperative fluoroscopy has to be recommended for femoral tunnel placement in daily surgical practice to minimize the incidence of malpositioning and to restore native patellofemoral biomechanics. STUDY DESIGN: Level III Case-control study.

BACKGROUND: Restoration of the mechanical axis is a main objective in total knee replacement (TKR). Aim of this study was to analyse the verification tool of a pinless navigation system in conventional TKR (cTKR). METHODS: In a prospective study, 147 TKR were performed by conventional technique. Using the "pinless verification" mode of a smartphone based navigation system, the cutting block position and final resection plane for distal femur and proximal tibial resection were measured. If necessary, the block position or resection level were optimized, corrections were protocolled. Postoperatively, standardized radiographs were performed. RESULTS: In 65.3%, intraoperative measurements changed the surgical procedure (corrections: 20.4% femoral, 25.9% tibial, 19% both). The additional time for surgery compared to cTKR averaged 6 minutes (79 ± 15 versus 73 ± 17 minutes). Using navigation data, the final femoral and tibial axes were in 93% within a range of ±2°. A mean difference of 1.4° and 1.6° could be shown between the final measurement of the navigation system and the postoperative mLDFA and mMPTA. CONCLUSION: Intraoperative pinless navigation has impact on the surgical procedure in the majority of cTKR. It represents a less time-consuming tool to improve implant position while maintaining the routine of conventional technique.
ABSTRACT
Ruptures of the tendon of the tibialis anterior muscle tend to occur in the context of degenerative impairments. This mainly affects the distal avascular portion of the tendon. Owing to the good compensation through the extensor hallucis longus and extensor digitorum muscles, diagnosis is often delayed. In addition to the clinical examination, magnetic resonance inaging (MRI) diagnostics are of particular importance, although damage or rupture of the tendon can also be demonstrated sonographically. Therapeutic measures include conservative or operative measures, depending on the clinical symptoms. Conservative stabilization of the ankle can be achieved by avoiding plantar flexion using a peroneal orthosis or an ankle-foot orthosis. Subsequent problems, such as metatarsalgia or overloading of the medial foot edge can be addressed by insoles or a corresponding shoe adjustment. An operative procedure is indicated when there is corresponding suffering due to pressure and functional impairment. The direct end-to-end reconstruction of the tendon is only rarely possible in cases of delayed diagnosis due to the degenerative situation and the retraction of the tendon stumps. Depending on the defect size and the tendon quality, various operative techniques, such as rotationplasty, free transplants or tendon transfer can be used.

OBJECTIVE: Realignment and pain relief of toes 2-5 by flexor-to-extensor tendon transfer of the flexor digitorum longus (FDL) muscle. INDICATIONS: As an isolated procedure in flexible proximal interphalangeal (PIP) joint flexion and/or flexible metatarsophalangeal (MTP) joint extension (hammer toe). In combination with a metatarsal osteotomy or PIP joint arthrodesis in case of flexible MTP joint extension. CONTRAINDICATIONS: General medical contraindications to surgical interventions. Stiffness of the PIP or MTP joint. SURGICAL TECHNIQUE: Plantar stab incision in the distal interphalangeal (DIP) flexion crease and tenotomy of the FDL tendon. More proximally transverse incision on the plantar aspect of the proximal phalanx and isolation of the FDL tendon. The tendon is split longitudinally along the raphe and the two limbs are transferred from plantar to the dorsal aspect of the proximal phalanx adjacent to the bone. The crossed limbs are sutured to each other under appropriate tension and corrected position of the toe. POSTOPERATIVE MANAGEMENT: Postoperative dressings for 3 weeks in corrected position. Subsequently tape dressing in plantar position for 6-12 weeks. Full weight bearing. RESULTS: A total of 24 toes with flexible PIP and/or MTP joint deformity were treated with a FDL tendon transfer. In 14 toes an isolated procedure was performed, in 10 cases an additional metatarsal osteotomy. Patients with operative treatment of the first ray, revision or reoperation were excluded. Mean follow-up was 8.4 (4-14) months. After 6 weeks 22 toes (92%) showed physiological alignment of the PIP and MTP joint. At the last follow-up, 4 (16%) toes had recurrent or persistent extension deformity of the MTP joint. There were no infections, overcorrections, impaired wound healing or transversal malalignment.

Patient safety has become a central and measurable key factor in the routine daily medical practice. The human factor plays a decisive role in safety culture and has moved into focus regarding the reduction of treatment errors and undesired critical incidents. Nonetheless, the systematic training in communication and interpersonal competences has so far only played a minor role. The German Society of Orthopaedics and Trauma (DGOU) in cooperation with the Lufthansa Aviation Training initiated a course system for interpersonal competence. Several studies confirmed the reduction of critical incidents and costs after implementation of a regular and targeted human factor training. The interpersonal competence should be an essential component of specialist training within the framework of a 3column model.

The hallux valgus represents combined bony and soft tissue pathology. In addition to known bony surgical procedures, addressing the soft tissue with regard to the anatomical structures, the surgical technique and the extent of correction are discussed.The goal of the operation is the restoration of the physiological balance between the active and passive stabilizing factors of the MTP-I-joint. The joint capsule, the ligaments and the tendons of the first ray act directly as stabilizing structures, whereas the hind foot and the position of the upper ankle have an indirect influence on the MTP-I-joint.The present work gives an overview of the pathoanatomy of the MTP-I-joint in the hallux valgus pathology. The individual anatomical structures are presented with regard to their physiological and pathological influence and the possible therapeutic options.

Patient safety has increasingly gained significance as criterion which clinics and doctors will be measured against in terms of ethics and finances. The "human factor" moved into focus regarding the question of how to reduce treatment errors in clinical daily routine. Nevertheless, systematic mediation of interpersonal competences only plays a minor role in the catalogue of requirements for medical specialization and professional training. This is the case not only in orthopedics and traumatology, but in other medical fields as well. At the insistence of DGOU and in cooperation with Lufthansa Flight Training, a training model was initiated, comparable to training models used in aviation. In aviation, apart from the training of procedural and technical abilities, regular soft skills training has become standard in the training of all Lufthansa staff. Several studies confirm that by improving communication, interaction, and teamwork skills not only a reduction of intolerable incidents is observed, but also a positive economic effect. Interpersonal competences should be firmly anchored in orthopedics and traumatology and thus be implemented as third post in specialist training.

The German Trauma Registry DGU® started in 1993 as an initiative of five dedicated trauma centers and has evolved significantly since then. Data were obtained at four points of time from the site of the accident until discharge from hospital. In the first year (1993), the registry collected data of 260 patients from 5 hospitals. In 2015 more than 38.000 were included from 640 hospitals.This paper focusses on the impact of the trauma registry on the treatment of severely injured patients. Several authors could show that the data can be used by hospitals for benchmarking. This can help to detect problems in individual hospitals and to find solutions that can be implemented into the process of care and its subsequent reevaluation. Due to structural and process-related changes, the time necessary for the management in the emergency room could be reduced significantly. Various scientific analyses of the Trauma Registry DGU® data were implemented in the treatment of severely injured patients. In the prehospital treatment, this changed the criteria for intubation and led to a reduction of volume replacement. In the hospital setting, the analysis influenced the radiologic work-up and the treatment of coagulopathy of severely injured patients. Moreover, the risk-adjusted mortality of severely injured patients in Germany could be continuously reduced over the past 20 years.

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.

PURPOSE: The reliability of the Rockwood classification, the gold standard for acute acromioclavicular (AC) joint separations, has not yet been tested. The purpose of this study was to investigate the reliability of visual and measured AC joint lesion grades according to the Rockwood classification. METHODS: Four investigators (two shoulder specialists and two second-year residents) examined radiographs (bilateral panoramic stress and axial views) in 58 patients and graded the injury according to the Rockwood classification using the following sequence: (1) visual classification of the AC joint lesion, (2) digital measurement of the coracoclavicular distance (CCD) and the horizontal dislocation (HD) with Osirix Dicom Viewer (Pixmeo, Switzerland), (3) classification of the AC joint lesion according to the measurements and (4) repetition of (1) and (2) after repeated anonymization by an independent physician. Visual and measured Rockwood grades as well as the CCD and HD of every patient were documented, and a CC index was calculated (CCD injured/CCD healthy). All records were then used to evaluate intra- and interobserver reliability. RESULTS: The disagreement between visual and measured diagnosis ranged from 6.9 to 27.6 %. Interobserver reliability for visual diagnosis was good (0.72-0.74) and excellent (0.85-0.93) for measured Rockwood grades. Intraobserver reliability was good to excellent (0.67-0.93) for visual diagnosis and excellent for measured diagnosis (0.90-0.97). The correlations between measurements of the axial view varied from 0.68 to 0.98 (good to excellent) for interobserver reliability and from 0.90 to 0.97 (excellent) for intraobserver reliability. CONCLUSION: Bilateral panoramic stress and axial radiographs are reliable examinations for grading AC joint injuries according to Rockwood's classification. Clinicians of all experience levels can precisely classify AC joint lesions according to the Rockwood classification. We recommend to grade acute ACG lesions by performing a digital measurement instead of a sole visual diagnosis because of the higher intra- and interobserver reliability. LEVEL OF EVIDENCE: Case series, Level IV.

BACKGROUND: Limiting the morbidity of open fractures requires highly specific initial treatment. In addition to a stringent surgical strategy, correct antibiotic prophylaxis seems to be associated with an improved outcome. In the current literature, the duration and type of antibiotic prophylaxis are under discussion. The aim of the study was to survey the current initial treatment regimes for open fractures in German emergency departments. MATERIAL AND METHODS: With an online-based anonymous 16-item questionnaire all 3006 members of the German Trauma Society were surveyed. A total of 585 questionnaires (19.5 %) were returned completed. This article presents a descriptive analysis of the current state of treatment. RESULTS: Mainly specialists (35 %), senior physicians (30 %) and chief physicians (17 %) answered as well as interns (8 %) and out-patient practitioners (10 %). Of the participants 65 % did not accept the classification of emergency services; however, 93 % carried out urgent or emergency surgery, 84 % started an antibiotic prophylaxis in the emergency department and 63 % used a standard operating procedure (SOP). A total of 60 % used 1 antibiotic drug, 25 % used 2 and 15 % used 3 or more substances. An antibiotic treatment for more than 3 days was performed by 60 % of participants. CONCLUSION: The early initiation of antibiotic prophylaxis seems to be the standard practice in German emergency departments as well as early surgery. Strategies to improve the communication between prehospital and in-hospital teams, as well as graded antibiotic prophylaxis depending on the severity of soft tissue damage are needed.

OBJECTIVE: Distal, lateral soft tissue release to restore mediolateral balance of the first metatarsophalangeal (MTP) joint in hallux valgus deformity. Incision of the adductor hallucis tendon from the fibular sesamoid, the lateral capsule, the lateral collateral ligament, and the lateral metatarsosesamoid ligament. INDICATIONS: Hallux valgus deformities or recurrent hallux valgus deformities with an incongruent MTP joint. CONTRAINDICATIONS: General medical contraindications to surgical interventions. Painful stiffness of the MTP joint, osteonecrosis, congruent joint. Relative contraindications: connective tissue diseases (Marfan syndrome, Ehler-Danlos syndrome). SURGICAL TECHNIQUE: Longitudinal, dorsal incision in the first intermetatarsal web space between the first and second MTP joint. Blunt dissection and identification of the adductor hallucis tendon. Release of the adductor tendon from the fibular sesamoid. Incision of the lateral capsule, the lateral collateral ligament, and the lateral metatarsosesamoid ligament. POSTOPERATIVE MANAGEMENT: Postoperative management depends on bony correction. In joint-preserving procedures, dressing for 3 weeks in corrected position. Subsequently hallux valgus orthosis at night and a toe spreader for a further 3 months. Passive mobilization of the first MTP joint. Postoperative weight-bearing according to the osteotomy. RESULTS: A total of 31 patients with isolated hallux valgus deformity underwent surgery with a Chevron and Akin osteotomy and a distal medial and lateral soft tissue balancing. The mean preoperative intermetatarsal (IMA) angle was 12.3° (range 11-15°); the hallux valgus (HV) angle was 28.2° (25-36°). The mean follow-up was 16.4 months (range 12-22 months). The mean postoperative IMA correction ranged between 2 and 7° (mean 5.2°); the mean HV correction was 15.5° (range 9-21°). In all, 29 patients (93%) were satisfied or very satisfied with the postoperative outcome, while 2 patients (7%) were not satisfied due to one delayed wound healing and one recurrent hallux valgus deformity. There were no infections, clinical and radiological signs of avascular necrosis of the metatarsal head, overcorrection with hallux varus deformity, or significant stiffness of the first MTP joint.

BACKGROUND AND OBJECTIVES: Accident prevention strategies aim to inform young people about risk-taking behavior and the consequences of trauma. The Prevent Alcohol and Risk-related Trauma in Youth (P.A.R.T.Y.) program is an accident prevention program that focuses on the prevention of road traffic accidents among young road users. Initial results of the program were evaluated to find out if the implementation of this prevention program is feasible in Germany. MATERIAL AND METHODS: During a 1-day interactive course young road users were introduced to the work carried out in an accident trauma unit and were informed about injury mechanisms and about the consequences of trauma. A systematic evaluation was made by all participants. The results were analyzed to find out whether it is possible to implement the program and the impressions gained by the participants of the program in order to be able to make further adjustments. RESULTS: A total of 219 young road users participated in the P.A.R.T.Y. program between 2011 and 2013. All participants reviewed the structure of the program with the help of school grades. Of the participants 59 % (n = 129) rated the program as "very good" and 41 % gave the rating of "good". Overall, 70 % of all participants advocated that all people of the same age should participate in the program. The structure was described as being well-balanced with respect to the theoretical and practical stations. CONCLUSION: The P.A.R.T.Y. program is a standardized and well-established concept that can also contribute to accident prevention in Germany. It provides the possibility to implement an accident awareness program throughout Germany. Initial results show that the program can be implemented in German hospitals and that the program appeals to the target group of young road users.

BACKGROUND: Penetrating injuries are rare in European populations so their management represents a particular challenge. The aim was to assess early therapeutic aspects that are associated with favourable outcomes in patients with penetrating trauma. METHODS: Patients with penetrating injuries documented from 2009 to 2013 in the TraumaRegister DGU® were analysed. Patients with a primary admission and an Injury Severity Score (ISS) of at least 9 were included. The Revised Injury Severity Classification (RISC) II score was used for mortality prediction, and a standardized mortality ratio (SMR) calculated per hospital. Hospitals with favourable outcome (SMR below 1) were compared with those with poor outcome (SMR 1 or more). RESULTS: A total of 50 centres had favourable outcome (1242 patients; observed mortality rate 15.7 per cent) and 34 centres had poor outcome (918 patients; observed mortality rate 24.4 per cent). Predicted mortality rates according to RISC-II were 20.4 and 20.5 per cent respectively. Mean(s.d.) ISS values were 22(14) versus 21(14) (P = 0.121). Patients in the favourable outcome group had a significantly shorter time before admission to hospital and a lower intubation rate. They received smaller quantities of intravenous fluids on admission to the emergency room, but larger amounts of fresh frozen plasma, and were more likely to receive haemostatic agents. A higher proportion of patients in the favourable outcome group were treated in a level I trauma centre. Independent risk factors for hospital death following penetrating trauma identified by multivariable analysis included gunshot injury mechanism and treatment in non-level I centres. CONCLUSION: Among penetrating traumas, gunshot injuries pose an independent risk of death. Treatment of penetrating trauma in a level I trauma centre was significantly and independently associated with lower hospital mortality.

An algorithmic strategy to determine the minimal fusion area of a tibia pseudarthrosis to achieve mechanical stability is presented. For this purpose, a workflow capable for implementation into clinical routine workup of tibia pseudarthrosis was developed using visual computing algorithms for image segmentation, that is a coarsening protocol to reduce computational effort resulting in an individualized volume-mesh based on computed tomography data. An algorithm detecting the minimal amount of fracture union necessary to allow physiological loading without subjecting the implant to stresses and strains that might result in implant failure is developed. The feasibility of the algorithm in terms of computational effort is demonstrated. Numerical finite element simulations show that the minimal fusion area of a tibia pseudarthrosis can be less than 90% of the full circumferential area given a defined maximal von Mises stress in the implant of 80% of the total stress arising in a complete pseudarthrosis of the tibia.

BACKGROUND: The goal of the present study was to summarize current treatment for acute acromioclavicular (AC) joint dislocations. METHOD: In all, 796 orthopedics and/or trauma departments in Germany were identified in the national hospital directory (www.dka.de). Using the respective hospital web sites, the email addresses of the responsible shoulder/sports surgeon or, if not available, the head of department (successful in 746 cases) were identified. Emails with a link to an online survey with 36 questions and two reminders were sent; 60 were undeliverable. Thus, 686 emails probably reached the addressee. A total of 203 colleagues (30%) participated in the survey. Findings were compared to results of the survey published by Bäthis et al. in 2001. RESULTS: More than 90% treat Rockwood I or II injuries conservatively and Rockwood IV to VI injuries surgically. However, 34% answered having never seen a Rockwood VI injury. Of those replying, 73% prefer surgical treatment for Rockwood III injuries. Favored surgical techniques were the hook plate in 44% and the arthoscopic TightRope® in 27%, while 11% prefer coracoclavicular cerclage, 6% AC joint transfixation, 3% minimally invasive AC joint reconstruction (MINAR), 1% coracoclavicular screw fixation, and 8% a completely different procedure. Concerning acute Rockwood III injuries, orthopedics and/or trauma surgeons still prefer surgical treatment but less often than 10 years ago (84%). CONCLUSIONS: Favored techniques have completely changed since 2001 when the majority of physicians preferred AC joint transfixation or coracoclavicular cerclages, both techniques that are hardly used today. The hook plate appears to have become "standard therapy". The arthroscopic TightRope® is the second most common despite being the newest technique.

BACKGROUND: In recent years, the treatment of trauma-associated coagulopathy and bleeding has advanced enormously. The aim of this study was to assess the current practice of coagulation and transfusion management in Germany. PATIENTS AND METHODS: From October 2011 until January 2012 we conducted a survey via online-questionnaire that was sent per E-Mail to all members of the German Society for Trauma Surgery. It comprised 12 questions with respect to current treatment of coagulopathy and haemorrhage in trauma patients. RESULTS: The response rate was 145/3006 (5 %). The respondents had following specialties: 77.2 % trauma surgery 15.9 % anesthesiology, 6.9 % others. 64 % of respondents were employed by a Level 1 trauma centre, wheras 17 % worked in a local level 3 centre. The majority (94 %) claimed to treat hypothermia regularly. Only about half of the participants reported to follow a massive transfusion protocol in their institution. The potential components of these protocols were reported in varying rates, being it well-established components (e.g. FFP 78 %; Fibrinogen 75 %) or therapies with poor evidence in multiple trauma (Desmopressin 39 %, rFVIIa 47 %). Calcium was provided by only 48 % of respondents although generally recommended in all guidelines. CONCLUSION: The current study suggests that in Germany strategies and principles regarding management of trauma-associated coagulopathy are standardized only poorly. Level 1 centres appear to apply a more advanced approach, however to much variability exists with respect to the components of the transfusion protocols. The low response rate indicates that most German trauma surgeons consider coagulation and hemorrhage as "expert-topics" beyond their field of duty.

Uncontrolled bleeding is the leading cause of shock in trauma patients and delays in recognition and treatment have been linked to adverse outcomes. For prompt detection and management of hypovolaemic shock, ATLS(®) suggests four shock classes based upon vital signs and an estimated blood loss in percent. Although this classification has been widely implemented over the past decades, there is still no clear prospective evidence to fully support this classification. In contrast, it has recently been shown that this classification may be associated with substantial deficits. A retrospective analysis of data derived from the TraumaRegister DGU(®) indicated that only 9.3% of all trauma patients could be allocated into one of the ATLS(®) shock classes when a combination of the three vital signs heart rate, systolic blood pressure and Glasgow Coma Scale was assessed. Consequently, more than 90% of all trauma patients could not be classified according to the ATLS(®) classification of hypovolaemic shock. Further analyses including also data from the UK-based TARN registry suggested that ATLS(®) may overestimate the degree of tachycardia associated with hypotension and underestimate mental disability in the presence of hypovolaemic shock. This finding was independent from pre-hospital treatment as well as from the presence or absence of a severe traumatic brain injury. Interestingly, even the underlying trauma mechanism (blunt or penetrating) had no influence on the number of patients who could be allocated adequately. Considering these potential deficits associated with the ATLS(®) classification of hypovolaemic shock, an online survey among 383 European ATLS(®) course instructors and directors was performed to assess the actual appreciation and confidence in this tool during daily clinical trauma care. Interestingly, less than half (48%) of all respondents declared that they would assess a potential circulatory depletion within the primary survey according to the ATLS(®) classification of hypovolaemic shock. Based on these observations, a critical reappraisal of the current ATLS(®) classification of hypovolaemic seems warranted.
