[Parameters influencing the preclinical application of cervical collars]. / Einflussfaktoren auf die präklinische Anlage einer Zervikalstütze.

BACKGROUND: The application of cervical collars is a standard procedure in emergency care of trauma patients. It is often observed that the application of cervical collars is performed incorrectly, which may lead to reduced immobilization of the cervical spine. OBJECTIVES: The objective of this study was to analyze the practical skills of professional emergency care providers concerning the application of cervical collars. MATERIALS AND METHODS: Emergency care professionals (n = 104) were asked to apply a cervical collar to a training doll. Each performance step was assessed separately. Furthermore, personal and occupational data of all study participants were collected using a questionnaire. RESULTS: The study participants included professional rescue personnel and emergency physicians. The average occupational experience of all study participants in out-of-hospital emergency care was 11.1 ± 8.9 years. Most participants had already received training on trauma care (61 %) and felt "very confident" in handling a cervical collar (84 %). The application of the cervical collar was performed correctly in 11 % of the performances. The most common error was incorrect size adjustment of the cervical collar (66 %). No association was found between the correct application of the cervical collar and possible parameters of influence, such as working experience in emergency care or participation in trauma courses. CONCLUSIONS: Despite pronounced subjective confidence regarding the application of cervical collars, this study shows that there are general deficits in the practical skills of applying cervical collars. Therefore, a critical assessment of the current training contents on the subject of trauma care must be demanded.

[Standardisation of the Initial Treatment of Severely Burned Patients: The Necessary Transfer of Concepts from Trauma Care]. / Standardisierung der Initialbehandlung von Schwerbrandverletzten: Die notwendige Übertragung von Konzepten aus der Schwerverletztenversorgung.

The initial treatment of severely burned patients remains a huge challenge for first responders in emergency services as well as emergency doctors who do not work in a centre for severe burn injuries. The reason for this is the low number of cases in developed countries and a lack of training concepts for the specific aspects of the initial treatment of severe burn injuries. Because of guidelines with limited evidence (S1, S2k) and a lack of structured treatment approaches, uncertainties with respect to initial treatment are still visible. Even within the professional societies and on international comparison, controversial aspects remain. In contrast, optimised and standardised procedures are available for the treatment of severely injured (trauma) patients, based on PHTLS® (Pre Hospital Trauma Life Support) for preclinical and ATLS® (Advanced Trauma Life Support) for in-hospital first aid. This article takes stock of the current structure of care and the relevant evidence for the initial treatment of severe burns. Also it discusses a possible transfer and further development of concepts for primary trauma care by all disciplines involved. Nine essential steps in the primary care of burned patients are identified and evaluated. The need for the introduction of a uniform treatment algorithm is illustrated. The treatment algorithm presented in this article addresses all first responders who are faced with initial treatment in the first 24 hours outside of burn centres. As an essential, new aspect, it offers a transfer and adaptation of concepts from trauma care to standardise the care of severely burned patients.

[Essential measures for prehospital treatment of severely injured patients: The trauma care bundle]. / Wesentliche Maßnahmen zur prähospitalen Versorgung schwerverletzter Patienten: Das Trauma Care Bundle.

BACKGROUND: In order to ensure adequate treatment and to avoid complications, care bundles are increasingly being implemented. These are comprehensive and evidence-based procedures for the treatment of individual diseases or injuries which should be carried out for every patient. The aim of this study was to define a care bundle for the prehospital treatment of severely injured patients. MATERIAL AND METHODS: The scientific contents of the bundle were gathered from the interdisciplinary evidence-based S3 guidelines for the treatment of severely injured patients by the German Trauma Society. The ABCDE scheme suggested by the prehospital trauma life support (PHTLS®) and the advanced trauma life support (ATLS®) functioned as a matrix for the individual elements in the bundles. The identified elements were finalized by a consensus process. RESULTS AND DISCUSSION: A bundle of six elements was suggested and a comprehensive summary of key items during prehospital management of severely injured patients was identified. In a next step the effectiveness of the care bundle should be evaluated in a clinical trial.

Does ATLS trauma training fit into Western countries: evaluation of the first 8 years of ATLS in Germany.

BACKGROUND: With over 2 million certified physicians worldwide, the Advanced Trauma Life Support (ATLS) program is one of the most successful international medical education programs. Germany joined the ATLS program in 2003. Before implementation of the program, there was a controversial discussion as to whether a country like Germany with a long history of trauma care needed ATLS at all. 197 courses with nearly 3,000 providers were performed until December 2010. AIM: We assessed the course evaluations since the implementation of ATLS in Germany using the participants' systematic feedback. METHOD: During the course, each participant evaluated each presentation, skill station, and simulation on a rating scale from 1 to 4 (1 being the best, 4 being the worst). The participants completed the evaluation forms during the course and before they received their results. The course coordinator made sure that all forms were returned. The feedback forms were collected anonymously and were entered into a database. Statistical analysis was performed using frequencies and mean values. RESULTS: The cumulative evaluation of all courses revealed an average performance score of 1.39 (1.06-1.86; n = 197). The lectures, skill stations, and simulations were individually evaluated as follows: lectures 1.61 (1.00-2.81; n = 197), skill stations 1.40 (1.00-2.40; n = 197), and surgical skill stations 1.35 (1.00-2.38; n = 197). Practical skills simulation (case scenarios) received the highest grade of 1.24 (1.00-1.57; n = 197). There were no significant changes during the time concerning the results of the evaluation. CONCLUSION: The overall assessment showed constantly good and excellent evaluations by the participants over the years. In general, skill stations and simulations performed better than lectures. According to these results, the course format is well accepted by the participants and, therefore, can be recommended to all physicians treating trauma patients. Our results also underline the value of such a course format in an industrial country with an already established trauma system.

[Results of nonunion treatment with bone morphogenetic protein 7 (BMP-7)]. / Ergebnisse der Pseudarthrosenbehandlung mit "bone morphogenetic protein 7" (BMP-7).

BACKGROUND: Complex patterns of impaired bone healing can result in a severe economic and social burden for the patient. Herein we describe the local application of recombinant human bone morphogenetic protein 7 (BMP-7). The goal of this prospective study is to review the indications, application and validation of this therapy. MATERIAL AND METHOD: From June 2002 to June 2008, we applied 101 BMP-7 treatments in 101 nonunions of 98 patients. The average age of the patients was 50 years (18-88 years). The gender composition was 29 women (30%) and 69 men (70%). Before BMP-7 application, patients had already underwent surgical treatement an average of 3.3 times (median 3, 1- to 13-times). We used BMP-7 "off-label" in all long bones. RESULTS: In 93 cases (92%), we observed proper bone healing. The average healing time was 4.8 months (range 1.5-11 months). The average time from injury to BMP-7 application was 18.4 months (3-84 months). In 65 cases, BMP-7 application was combined with re-osteosynthesis and autologous bone grafting. Serious side effects were not observed. CONCLUSIONS: BMP-7 should not be used as general treatment of nonunion in all patients, but appears to be effective for the treatment of complex cases. In clinical practice, the decision to proceed with off-label use of BMP-7 should be made on a case-by-case basis.

Cigarette smoking decreases TGF-b1 serum concentrations after long bone fracture.

TGF-b1 serum concentrations are considered to be one of the most promising markers of fracture healing. Previously, we demonstrated significant differences in the post-traumatic time courses of patients with timely and delayed fracture healing. The aim of this study was to evaluate possible differences in the serum concentrations of TGF-b1 in cigarette-smoking vs. non-smoking patients with timely and delayed fracture healing in order to understand pathophysiological pathways through which smoking impairs fracture healing.Serum samples were collected from 248 patients undergoing surgical treatment for long bone fractures within 1 year of surgery. Samples from 14 patients with atrophic-type delayed fracture healing were compared with 14 matched patients with normal bone healing. Each group included seven smokers and seven non-smokers. Post-operative serum concentrations were analysed at 1, 2, 4, 8, and 12 weeks as well as 1 year after surgery. The patients were monitored both clinically and radiologically for the entire duration of the study.All patients increased TGF-b1 serum concentrations after surgery. In patients with normal fracture healing, significantly higher TGF-b1 levels were observed in non-smokers (70 ng/ml) than in smokers(50 ng/ml) at the 4th week after surgery (p = 0.007). Also at the 4th week, in patients with delayed healing, significantly lower TGF-b1 levels were observed in smokers than in non-smokers (38 ng/ml vs.47 ng/ml, p = 0.021). However, no significant differences between non-smokers with delayed healing and smokers with normal healing (p = 0.151) were observed at the 4th week after surgery. TGF-b1 serum concentrations reached a plateau in all groups from the 6th to the 12th week after surgery, with a slight decrease observed in the final measurement taken 1 year after surgery.This study demonstrates that, after fracture, TGF-b1 serum concentrations are reduced by smoking,and this reduction is statistically significant during the 4th week after surgery. Our findings may help reveal the mechanism by which smoking impairs fracture healing. Furthermore, these results may help to establish a serological marker that predicts impaired fracture healing soon after the injury. Surgeons will not only be able to monitor the bone healing, but they will also be able to monitor the success of additional treatments such as ultrasound and bone morphologic proteins (BMPs).

[Six years of Advanced Trauma Life Support (ATLS) in Germany: the 100th provider course in Hamburg]. / Sechs Jahre Advanced Trauma Life Support (ATLS) in Deutschland: 100. Providerkurs in Hamburg.

With over 1 million certified physicians in more than 50 countries worldwide, the Advanced Trauma Life Support (ATLS) concept is one of the most successful international education programs. The concept is simple, priority-orientated (ABCDE scheme) and assesses the situation of the trauma patient on the basis of vital signs to treat the life-threatening injuries immediately. With over 100 ATLS provider courses and 10 instruction courses accomplished in less than 6 years, no other land in the world has successfully established this concept in such a short time as Germany. Meanwhile nearly 1,600 colleagues have been trained and certified. Evaluation of the first 100 ATLS courses in Germany supports this concept. The total evaluation of all courses is 1.36 (1.06-1.8, n=100). The individual parts of the course were marked as followed: presentations 1.6 (1.0-2.81, n=100), practical skills stations 1.46 (1.0-2.4, n=100) and surgical skills stations 1.38 (1.0-2.38, n=100). In 2009 a total of 47 ATLS courses were accomplished which will clearly increase in 2010. Other ATLS formats, such as ATCN (Advanced Trauma Care for Nurses) and refresher courses are planned for the beginning of 2010.

[Standardised primary care of multiple trauma patients. Prehospital Trauma Life Support und Advanced Trauma Life Support]. / Standardisierte Primärtherapie des polytraumatisierten Patienten. Prehospital Trauma Life Support und Advanced Trauma Life Support.

INTRODUCTION: Standardised management improves treatment results in seriously injured patients. For conditions like stroke or acute coronary syndrome (ACS) there are set treatment pathways which have been established for prehospital and primary hospital care. The treatment of critical trauma patients, however, follows varying procedures in both the prehospital and primary hospital phases. From an analysis of the trauma register of the German Society for Trauma Surgery (DGU), we know that a seriously injured patient remains on the road for 70 min on average before transferral to hospital. This requires improvement. With the 2003 introduction of the ATLS programme in Germany, the initial clinical phase could be improved upon simply by means of standardised training. PHTLS und ATLS complement one another. RESULTS: PHTLS und ATLS represent training concepts which teach standardised, priority-based prehospital and hospital trauma management. The aim is to make an initial rapid and accurate assessment of the patient's condition, thereby identifying the"critical" patient. The concepts also make priority-based treatment possible and facilitate decision-making as to whether patients can receive further on-the-spot treatment or whether immediate transport is necessary. The procedure is identical in the shock room. The primary consideration is to prevent secondary damage, not to lose track of time and to ensure consistent quality of care. The courses teach systematic knowledge, techniques, skills and conduct in diagnosis and therapy. The courses are oriented to all medical specialities associated with trauma care. With the support of the German Society for Trauma Surgery (DGU) and the German Society for Anesthesiology and Intensive Medicine (DGAI), the German Professional Organisation of Rescue Services (DBRD) has adopted the PHTLS course system on licence from the National Association of Emergency Medical Technicians (NAEMT) and the American College of Surgeons (ACS) and has been offering it in Germany since late 2007. ATLS was established by the DGU in 2003 and represents successful and similarly structured shock-room management. CONCLUSION: PHTLS und ATLS are established and standardised concepts, which are constantly reviewed and updated according to the latest medical knowledge. They provide the opportunity to standardise prehospital and primary clinical trauma management for all specialties and hospitals, while incorporating own knowledge.

[Prehospital Trauma Life Support (PHTLS): An interdisciplinary training in preclinical trauma care]. / Prehospital Trauma Life Support (PHTLS): Ein interdisziplinäres Ausbildungskonzept für die präklinische Traumaversorgung.

INTRODUCTION: There is clinical evidence that standardized management of trauma patients in the emergency department improves outcome. Standardized prehospital management has been established for stroke patients and those suffering acute coronary syndrome. Prehospital treatment of trauma patients differs quite significantly from one system to another. The data from the German Trauma Registry show that the average time from accident until arrival in the emergency department is 72 min. This needs improvement. RESULTS: PHTLS is a training course that teaches a systematic approach to the trauma patient in the preclinical setting. The aim is to rapidly and accurately assess the patient's physiologic status, treat according to priorities, and decide whether the patient is critical and needs rapid rescue and transport. Above all, it is important for caregivers to prevent secondary injury, to realize the relevance of timing in the initial treatment, and to assure a high standard of care. PHTLS provides the participant with knowledge, skills, and necessary behaviors. The course is open to persons in all specialties involved in the initial management of severely injured patients. The German Board of Emergency Technicians e.V. inaugurated the course concept in cooperation with the National Association of Emergency Medical Technicians (NAEMT) and the American College of Surgeons (ACS) and is authorized to organize PHTLS courses in Germany. CONCLUSION: PHTLS teaches a standardized and established approach to the trauma patient in the emergency department. It has been established in 36 countries and the content is reviewed regularly to consider new scientific evidence. Healthcare personnel in Germany have the chance to participate in this international standard of care and to introduce their own experiences into the review process.

[WDoku: computer-based documentation of continuing education curricula in orthopaedics and trauma surgery]. / WDoku -- computerbasierte Dokumentation der Weiterbildungsinhalte Orthopädie und Unfallchirurgie.

With the introduction of the new regulations governing the postgraduate training for qualification as specialist in orthopaedics and trauma surgery it has become a requirement, as in all surgical disciplines, that a logbook is kept to document the content of training courses. In it the basic steps and techniques carried out, but especially the list of operations performed, are recorded. To create a convenient option for standardised documentation of the content of training courses and to make a "medical journal" for all doctors possible, a special computer program has been developed within a project at the BG Trauma Clinic in Ludwigshafen. The program is called WDoku, and it is based on the training course content prescribed by the medical associations in the different länder; it allows data import from internal clinic documentation programs. In addition to submittals for the annually required training interviews it makes it possible to print out a logbook so that candidates can register for the specialist examination with the medical associations.
