[Airwaymangement in Emergencies]. / Atemwegsmanagement im Notfall.

Emergency airway management is a rare but essential emergency medical intervention directly impacting morbidity and mortality of emergency patients. The success of airway management depends on various factors such as patient anatomy, environmental aspects and the provider performing the procedure. Therefore, the use of a clearly structured algorithm for anticipating the difficult airway in emergency situations is strongly recommended. Our article explains different ways of securing the airway as part of a structured algorithm as well as pitfalls and helpful tips.

Training Effectiveness and Impact on Safety, Treatment Quality, and Communication in Prehospital Emergency Care: The Prospective Longitudinal Mixed-Methods EPPTC Trial.

BACKGROUND: Emergency training is designed to improve medical care teams' knowledge, practical skills, and treatment procedures in patient care to increase patient safety. This requires effective training, but the multifactorial effects of training are difficult to measure. METHODS: We assessed the impact of emergency team training on treatment procedures and quality, processes, technical skills, and nontechnical skills in simulated trauma emergencies in a longitudinal analysis, using videos that were recorded before (t0), immediately after (t1), and 1 year after the training (t2). The training was evaluated with the validated PERFECT checklist, which includes 7 scales: primary assessment, secondary assessment, procedures, technical skills, trauma communication, nontechnical skills, and a global performance scale.The primary end point was the change from before a training intervention (t0) to 1 year after training (t2), measured by a metric point score. The second end point was the impact of the intervention from before training to after and from immediately after training to 1 year later. RESULTS: A total of 146 trainings were evaluated. In simulated traumatological emergencies, training participants showed significantly better treatment capacity after 1 year (t0: 28.8 ± 5.6 points versus t2: 59.6 ± 6.6 points, P < 0.001), with greater improvement from t0 to t1 (28.8 ± 5.6 points versus 65.1 ± 7.9 points, P < 0.001). The most significant change from t0 to t2 was seen in the primary assessment, with a mean change of 11.1 ± 5.1, followed by the scale of the procedure (6.1 ± 3.0) and nontechnical skills (6.0 ± 3.0). CONCLUSIONS: Team trainings with intensive scenario training and short theoretical inputs lead to a significant improvement in simulated care of severely injured patients, especially in identifying and intervening in life-threatening symptoms, processes, and nontechnical skills, even 1 year after the course. Positive, longitudinally positive effects were also in communication and subjective safety of prehospital health care personnel.

Performance Assessment of Emergency Teams and Communication in Trauma Care (PERFECT checklist)-Explorative analysis, development and validation of the PERFECT checklist: Part of the prospective longitudinal mixed-methods EPPTC trial.

BACKGROUND: Trainings in emergency medicine are well structured, but examinations are rarely validated. We are evaluating the impact of pre-hospital emergency trainings on participants and patient care and developed and validated a checklist to assess emergency trainings. METHODS: We used videos recorded at the time points directly before (t0), directly after (t1), and one year after (t2) training to develop the PERFECT checklist (Performance Assessment of Emergency Teams and Communication in Trauma Care). The videos were assessed using semi-qualitative/linguistic analysis as well as expert panel appraisal and recommendations using the Delphi method. The checklist was tested for validity and reliability. RESULTS: The inter-rater reliability (ICC = 0.99) and internal consistency (α = 0.99) were high. Concurrent validity was moderate to high (r = 0.65 -r = 0.93 (p<0.001)). We included scales for procedures, non-technical skills, technical skills and global performance. The procedures were done faster in the mean over the timeline (t0: 2:29, 95%CI 1:54-3:03 min., t1: 1:11, 95%C 0:53-1:30 min, t2: 1:14, 95%CI 0:56-1:31 min.). All experts rated the recorded scenarios at t0 with the lowest sum score (mean 31±8), with a significantly better performance of the teams at t1 (mean 69±7). The performance at t2 (mean 66 ± 13) was slightly lower than at t1, but still better than at t0. At t1 and t2, linguistic analysis showed a change in the team leaders communication behaviour, which can be interpreted as a surrogate parameter for reduced stress. CONCLUSION: The PERFECT checklist has a good validity and high reliability for assessing trauma procedures and teamwork.

Analgesia in Patients with Trauma in Emergency Medicine.

BACKGROUND: Suitable analgesic drugs and techniques are needed for the acute care of the approximately 18 200-18 400 seriously injured patients in Germany each year. METHODS: This systematic review and meta-analysis of analgesia in trauma patients was carried out on the basis of randomized, controlled trials and observational studies. A systematic search of the literature over the 10-year period ending in February 2016 was carried out in the PubMed, Google Scholar, and Springer Link Library databases. Some of the considered trials and studies were included in a meta-analysis. Mean differences (MD) of pain reduction or pain outcome as measured on the Numeric Rating Scale were taken as a summarizing measure of treatment efficacy. RESULTS: Out of 685 studies, 41 studies were considered and 10 studies were included in the meta-analysis. Among the drugs and drug combinations studied, none was clearly superior to another with respect to pain relief. Neither fentanyl versus morphine (MD -0.10 with a 95% confidence interval of [-0.58; 0.39], p = 0.70) nor ketamine versus morphine (MD -1.27 [-3.71; 1.16], p = 0.31), or the combination of ketamine and morphine versus morphine alone (MD -1.23 [-2.29; -0.18], p = 0.02) showed clear superiority regarding analgesia. CONCLUSION: Ketamine, fentanyl, and morphine are suitable for analgesia in spontaneously breathing trauma patients. Fentanyl and ketamine have a rapid onset of action and a strong analgesic effect. Our quantitative meta-analysis revealed no evidence for the superiority of any of the three substances over the others. Suitable monitoring equipment, and expertise in emergency procedures are prerequisites for safe and effective analgesia by healthcare professionals..

Quality of Documentation as a Surrogate Marker for Awareness and Training Effectiveness of PHTLS-Courses. Part of the Prospective Longitudinal Mixed-Methods EPPTC-Trial.

OBJECTIVE: Care for severely injured patients requires multidisciplinary teamwork. A decrease in the number of accident victims ultimately affects the routine and skills. PHTLS ("Pre-Hospital Trauma Life Support") courses are established two-day courses for medical and non-medical rescue service personnel, aimed at improving the pre-hospital care of trauma patients worldwide. The study aims the examination of the quality of documentation before and after PHTLS courses as a surrogate endpoint of training effectiveness and awareness. METHODS: This was a prospective pre-post intervention trial and was part of the mixed-method longitudinal EPPTC (Effect of Paramedic Training on Pre-Hospital Trauma Care) study, evaluating subjective and objective changes among participants and real patient care, as a result of PHTLS courses. The courses provide an overview of the SAMPLE approach for interrogation of anamnestic information, which is believed to be responsible for patient safety as relevant, among others, "Allergies," "Medication," and "Patient History" (AMP). The focus of the course is not the documentation. RESULTS: In total, 320 protocols were analyzed before and after the training. The PHTLS course led to a significant increase (p < 0.001) in the "AMP" information in the documentation. The subgroups analysis of "allergies" (+47.2%), "drugs" (+38.1%), and "medical history" (+27.8%) before and after the PHTLS course showed a significant increase in the information content. CONCLUSION: In summary, we showed that PHTLS training improves documentation quality, which we used as a surrogate endpoint for learning effectiveness and awareness. In this regard, we demonstrated that participants use certain parts of training in real life, thereby suggesting that the learning methods of PHTLS training are effective. These results, however, do not indicate whether patient care has changed.

Comparison of the Prehospital Trauma Life Support recommendations and the German national guideline on treatment of patients with severe and multiple injuries.

BACKGROUND: The Prehospital Trauma Life Support (PHTLS) concept is well established throughout the world. The aim is to improve prehospital care for patients with major trauma. In 2011, a German Level 3 (S3) evidence- and consensus-based guideline on the treatment of patients with severe and multiple injuries was published. The scope of this study was the systematic comparison between the educational content of the worldwide PHTLS concept and the German S3 Guideline. METHODS: A total of 62 key recommendations of the German S3 Guideline were compared with the content of the English PHTLS manual (eighth edition). Depending on the level of agreement, the recommendations were categorized as (1) agreement, (2) minor variation, or (3) major variation. Comparison was done via a rating system by a number of international experts in the field of out-of-hospital trauma care. The Delphi method was used to get the final statements by indistinct or board-ranged ratings. RESULTS: Overall, there was no conformity in 12%. In 68% a total agreement and in 88% conformity with slight differences of minor variations were found between the key recommendations of the guideline and the PHTLS manual. The PHTLS primary assessment has a large conformity for the following individual priorities: airway, 92%; breathing, 92%; circulation, 63%; disability, 100%; exposure, 89%. CONCLUSIONS: According to our comparison, the PHTLS manual is largely compatible with the German S3 Guideline from 2011. The 12% divergent statements concern mainly fluid resuscitation. Minor deviations in the prehospital care are due to a national guideline with an emergency medical service with emergency physicians (S3 Guideline) and a global PHTLS concept.

Development of a new Emergency Medicine Spinal Immobilization Protocol for trauma patients and a test of applicability by German emergency care providers.

BACKGROUND: In order to match the challenges of quickly recognizing and treating any life-threatening injuries, the ABCDE principles were established for the assessment and treatment of trauma patients. The high priority of spine protection is emphasized by the fact that immobilization of the cervical spine is performed at the very first step in the ABCDE principles. Immobilization is typically performed to prevent or minimize secondary damage to the spinal cord if instability of the spinal column is suspected. Due to increasing reports about disadvantages of spinal immobilization, the indications for performing spinal immobilization must be refined. The aim of this study was (i) to develop a protocol that supports decision-making for spinal immobilization in adult trauma patients and (ii) to carry out the first applicability test by emergency medical personnel. METHODS: A structured literature search considering the literature from 1980 to 2014 was performed. Based on this literature and on the current guidelines, a new protocol that supports on scene decision-making for spinal immobilization has been developed. Parameters found in the literature concerning mechanisms and factors increasing the likelihood of spinal injury have been included in the new protocol. In order to test the applicability of the new protocol two surveys were performed on German emergency care providers by means of a questionnaire focused on correct decision-making if applying the protocol. RESULTS: Based on the current literature and guidelines, the Emergency Medicine Spinal Immobilization Protocol (E.M.S. IMMO Protocol) for adult trauma patients was developed. Following a fist applicability test involving 21 participants, the first version of the E.M.S. IMMO Protocol has to be graphically re-organized. A second applicability test comprised 50 participants with the current version of the protocol confirmed good applicability. Questions regarding immobilization of trauma patients could be answered properly using the E.M.S. IMMO Protocol. DISCUSSION: Current literature increasingly reports of disadvantages that may be associated with immobilization. Based on the requirements of the current guidelines, a new protocol that supports decision-making for indications for out-of-hospital spinal immobilization has been developed in this study. In contrast to established protocols, the new protocol offers different options for immobilization as well as a decicion-support. CONCLUSIONS: The E.M.S. IMMO protocol provides a decision-support tool for indications for spinal immobilization in adult trauma patients that permits variable decision-making depending on the current condition of the trauma patient and the pattern of injuries for immobilization in general and for immobilization method in particular.

Application of Cervical Collars - An Analysis of Practical Skills of Professional Emergency Medical Care Providers.

BACKGROUND/OBJECTIVE: The application of a cervical collar is a standard procedure in trauma patients in emergency medicine. It is often observed that cervical collars are applied incorrectly, resulting in reduced immobilization of the cervical spine. The objective of this study was to analyze the practical skills of trained professional rescue personnel concerning the application of cervical collars. MATERIAL AND METHODS: Within emergency medical conferences, n = 104 voluntary test subjects were asked to apply a cervical collar to a training doll, wherein each step that was performed received an evaluation. Furthermore, personal and occupational data of all study participants were collected using a questionnaire. RESULTS: The test subjects included professional rescue personnel (80.8%) and emergency physicians (12.5%). The average occupational experience of all study participants in pre-clinical emergency care was 11.1±8.9 years. Most study participants had already attended a certified training on trauma care (61%) and felt "very confident" in handling a cervical collar (84%). 11% applied the cervical collar to the training doll without errors. The most common error consisted of incorrect adjustment of the size of the cervical collar (66%). No association was found between the correct application of the cervical collar and the occupational group of the test subjects (trained rescue personnel vs. emergency physicians) or the participation in certified trauma courses. CONCLUSION: Despite pronounced subjective confidence regarding the application of cervical collars, this study allows the conclusion that there are general deficits in practical skills when cervical collars are applied. A critical assessment of the current training contents on the subject of trauma care must, therefore, be demanded.

PHTLS ® (Prehospital Trauma Life Support) provider courses in Germany - who takes part and what do participants think about prehospital trauma care training?

BACKGROUND: The goal of this study was to examine PHTLS Provider courses in Germany and to proof the assumption that formation of physicians and paramedics in prehospital trauma care can be optimized. METHODS: PHTLS participants were asked to fill out standardized questionnaires during their course preparation and directly after the course. There were some open questions regarding their professional background and closed questions concerning PHTLS itself. Further questions were to be answered on an analog scale in order to quantify subjective impressions of confidence, knowledge and also to describe individual levels of education and training. RESULTS: 247 questionnaires could be analyzed. Physicians noted significant (p < 0.001) more deficits in their professional training than paramedics. 80% of the paramedics affirmed to have had adequate training with respect to prehospital trauma care, all physicians claimed not to have had sufficient training for prehospital trauma care situations at Medical School. Physicians were statistically most significant dissatisfied then paramedics (p < 0.001). While most participants gave positive feedback, anesthetists were less convinced of PHTLS (p = 0.005), didn't benefit as much as the rest (p = 0.004) and stated more often, that the course was of less value for their daily work (p = 0.03). After the course confidence increased remarkably and reached higher rates than before the course (p < 0.001). After PHTLS both groups showed similar ratings concerning the course concept indicating that PHTLS could equalize some training deficits and help to gain confidence and assurance in prehospital trauma situations. 90% of the paramedics and 100% of the physicians would recommend PHTLS. Physicians and especially anesthetists revised their opinions with regard to providing PHTLS at Medical School after having taken part in a PHTLS course. CONCLUSION: The evaluation of PHTLS courses in Germany indicates the necessity for special prehospital trauma care training. Paramedics and physicians criticize deficits in their professional training, which can be compensated by PHTLS. With respect to relevant items like confidence and knowledge PHTLS leads to a statistically significant increase in ratings on a visual analogue scale. PHTLS should be integrated into the curriculum at Medical School.

The effect of paramedic training on pre-hospital trauma care (EPPTC-study): a study protocol for a prospective semi-qualitative observational trial.

BACKGROUND: Accidents are the leading cause of death in adults prior to middle age. The care of severely injured patients is an interdisciplinary challenge. Limited evidence is available concerning pre-hospital trauma care training programs and the advantage of such programs for trauma patients. The effect on trauma care procedures or on the safety of emergency crews on the scene is limited; however, there is a high level of experience and expert opinion. METHODS: I - Video-recorded case studies are the basis of an assessment tool and checklist being developed to verify the results of programs to train participants in the care of seriously injured patients, also known as "objective structured clinical examination" (OSCE). The timing, completeness and quality of the individual measures are assessed using appropriate scales. The evaluation of team communication and interaction will be analyzed with qualitative methods and quantified and verified by existing instruments (e.g. the Clinical Team Scale). The developed assessment tool is validated by several experts in the fields of trauma care, trauma research and medical education. II a) In a German emergency medical service, the subjective assessment of paramedics of their pre-hospital care of trauma patients is evaluated at three time points, namely before, immediately after and one year after training. b) The effect of a standardized course concept on the quality of documentation in actual field operations is determined based on three items relevant to patient safety before and after the course. c) The assessment tool will be used to assess the effect of a standardized course concept on procedures and team communication in pre-hospital trauma care using scenario-based case studies. DISCUSSION: This study explores the effect of training on paramedics. After successful study completion, further multicenter studies are conceivable, which would evaluate emergency-physician staffed teams. The influence on the patients and prehospital measures should be assessed based on a retrospective analysis of the emergency room data.

[Practice report: Structured training to improve quality of care in emergency medical service. On-scene supervision: A new approach to emergency medical service training in Wiesbaden and Rheingau-Taunus-Kreis?]. / Bericht aus der Praxis: Strukturierte Fortbildung zur Verbesserung der Versorgungsqualität im Rettungsdienst. Einsatz-Supervision als neuer Ansatz im Bereich der Rettungsdienst-Fortbildung in Wiesbaden und im Rheingau-Taunus-Kreis?

In recent years, the emergency medical services in Wiesbaden and the Rheingau-Taunus district made great efforts to standardise structures. Since there are only few established procedures in the annual examinations for paramedics, there is reason to assume that treatment procedures for patients have not been standardised either. Materials and equipment are not handled uniformly, and employee satisfaction has significantly decreased over the last few years. To solve these problems, all paramedics undergo standardised and structured trainings. These training courses make use of the internationally accepted PHTLS (Pre-Hospital Trauma Life Support) and AMLS (Advanced Life Support Medial) programmes. In addition, practising skills and handling the equipment as well as on-scene supervision is to be established in practical training sessions.
