Das Eckpunktepapier aus dem Jahr 2007 hat wichtige Rahmenbedingungen und Ziele definiert, die als Grundlage für Strukturanforderungen und die notfallmedizinische Planung dienten. Die steigenden Anforderungen an die notfallmedizinische Versorgung der Bevölkerung machen es erforderlich, das Eckpunktepapier 2007 zu aktualisieren und zu erweitern. Das Ergebnis der Überarbeitung wird in diesem Artikel präsentiert. Der Entwurf für das neue Eckpunktepapier wurde auf einem Symposium mit Vertretern der an der notfallmedizinischen Versorgung beteiligten Fachgesellschaften/Institutionen/Organisationen ausgearbeitet und in einer Plenumsitzung vorgestellt. Zur exakten Begriffsbestimmung wurde ein Glossar erstellt. In einem zweistufigen Konsensusverfahren wurden alle Dokumente in einem Umlaufverfahren überarbeitet und endgültig zur Abstimmung gebracht. Am Konsensus zum Eckpunktepapier beteiligten sich insgesamt 30 Fachgesellschaften/Institutionen/Organisationen. Die Zustimmungsrate entspricht mit 96,7 % einem starken Konsensus. Das „Eckpunktepapier 2016“ enthält nun Empfehlungen zur notfallmedizinischen Strukturplanung und zum notfallmedizinischen Vorgehen gemäß den geltenden Leitlinien und Anforderungen an die geeignete Zielklinik. Zusätzlich zu den bisherigen Tracerdiagnosen Schädel-Hirn-Trauma, Schlaganfall, Schwerverletzte/Polytrauma und ST-Hebungsinfarkt wurden in die Überarbeitung Empfehlungen zum plötzlichen Kreislaufstillstand und zur Sepsis aufgenommen. Betrachtet wurden jeweils die Prozessqualität der Rettungsleitstelle, Anforderungen für Diagnostik und Therapie durch Notarzt und Rettungsdienst, Einsatztaktik und Zeitmanagement, die klinische Erstversorgung in einem geeigneten Krankenhaus sowie Instrumente des Qualitätsmanagements. Zusätzlich sind die Besonderheiten bei der Versorgung pädiatrischer Patienten aufgeführt. Außerdem enthält das Papier Kernempfehlungen zum ersten Glied der Rettungskette (Risikoaufklärung, Erste Hilfe und Notruf). Das „Eckpunktpapier 2016“ berücksichtigt somit die gesamte notfallmedizinische Prozesskette vom Eintritt des Notfalls und dem Notrufeingang in der Rettungsleitstelle über die notärztliche/rettungsdienstliche Versorgung bis zur Weiterbehandlung im Krankenhaus und dient damit als Leitfaden für die integrierte Bedarfsplanung einer erreichbarkeitsorientierten Notfallversorgung.
Zusammenfassung Hintergrund Die Berichterstattung aus einzelnen Bundesländern zeigt über viele Jahre kontinuierlich steigende Einsatzzahlen im bodengebundenen Rettungsdienst. Fragestellung Ziel der Arbeit ist es aufzuzeigen, wie stark sich die Einsatzzahlen und das Einsatzspektrum im Rettungsdienst in den letzten Jahren entwickelt haben. Material und Methode Die Arbeit führt nach Literaturrecherche geeignete Publikationen synoptisch zusammen, um einen umfassenden Überblick der aktuellen Erkenntnisse zu geben. Ergebnisse Vollerhebungen der Einsatzzahlen einzelner Bundesländer sowie Hochrechnungen der Rettungsdiensteinsätze auf Bundesebene zeigen jährliche Zuwachsraten von etwa 5 %. Zudem belegen einzelne Untersuchungen vor allem einen Anstieg nichttraumatologischer Einsatzgründe. Sowohl die Einsatzzunahme als auch die Änderung im Einsatzspektrum können, neben weiteren Einflussfaktoren, u. a. auf den demografischen Wandel zurückgeführt werden. Schlussfolgerungen Um dem Anstieg und der Änderung der Inanspruchnahme zu begegnen, erscheint neben der Ausweitung bestehender Angebote der Notfallversorgung die Etablierung alternativer Ansätze (z. B. Telenotarzt) zielführend. Begleitend sollte eine umfassende Datenerfassung und -auswertung erfolgen, um im Rahmen des Qualitätsmanagements ein kontinuierliches Nachsteuern des Systems zu erlauben.
BACKGROUND: Pre-hospital emergency medical services (EMS) are an integral part of emergency medical care. EMS planning can be achieved by analyzing patterns of use. However, long-term time trends of EMS use have rarely been studied. The objective of this retrospective study was to investigate utilization patterns over a ten year period, and to compare utilization trends between urban and rural municipalities and between events with and without prehospital emergency physician (PEP) dispatch. METHODS: Routine data collected by 26 dispatch centers in the federal state of Bavaria, Germany, from 2007 to 2016 was analyzed. Emergency locations were classified into five levels of rurality. Negative binomial mixed effects regression models were fitted to predict emergency rates and to investigate differences in rates and utilization trends. Graphical representation methods were used to compare distribution of transport rates and distribution across daytime and weekday. RESULTS: Twelve million two hundred thousand one hundred fifty-five dispatches assigned to 7,725,636 single emergencies were included. The mean number of emergencies per year and 1000 population (emergency rate) was 42.8 (±16.0) in rural municipalities and 80.7 (±9.3) in large cities. Compared to rural municipalities, cities had higher emergency rates without (IRR = 3.0, CI 2.2-4.0) and with pre-hospital physicians (IRR = 1.5, CI 1.2-2.0). Between 2007 and 2016, the absolute number of emergencies increased by 49.1%. Estimated annual percent change of emergency rates without physician activation ranged from 5.7% (CI 4.3-7.1) in cities to 7.8% (CI 7.6-7.9) in rural areas. Changes in emergency rates with physician attendance were lower, with estimated increases between 1.3 and 2.4%. The average proportion of patients transported to a hospital was lower in cities and remained unchanged. There were no considerable differences or changes in the distribution across daytime and weekdays. CONCLUSION: Differences between cities and other areas suggest that the planning of EMS should be targeted to regional characteristics. A substantial increase in emergency rates was observed across all areas of Bavaria, but did not impact transport rates or temporal distributions. Further research is needed to better understand the urgency of emergency events and reasons behind increasing EMS utilization.
OBJECTIVE: Analyze sex differences in TraumaRegister DGU (TR-DGU). BACKGROUND: Sex differences are considered to influence trauma outcomes. However, clinical study results are controversial. METHODS: Of 29,353 prospectively recorded cases of TR-DGU, we included primary trauma room admissions with Injury Severity Score of 9 or more into the analysis. Pairs (n = 3887) were formed from 1 male and 1 female according to age, mechanism, injury severity by Abbreviated Injury Scale (for head, thorax, abdomen, extremities), and occurrence of prehospital shock. Biochemical markers, treatment modalities, length of stay, and outcome (multiple organ failure, sepsis, mortality rates) were assessed. Statistical significance was accepted at P < 0.05. Odds ratios (ORs) are given with 95% confidence interval (CI). RESULTS: Females had less multiple organ failure [OR: 1.18 (95% CI, 1.05-1.33); P = 0.007], particularly in age group of 16 to 44 years; sepsis [OR: 1.45 (95% CI, 1.21-1.74); P < 0.001]), particularly at age more than 45 years; and mortality [OR: 1.14 (95% CI, 1.01-1.28); P = 0.037]. Prehospital chest tube insertions (214 vs 158) and surgical procedures before intensive care unit admission were more often performed in males (79.7% vs 76.4%). Females had lower mean hemoglobin levels [10.7 ± 2.6 vs 11.9 ± 2.8 (mg/dL)]. There were no sex differences in fluid resuscitation, shock index, coagulation, and base excess. CONCLUSIONS: Males are more susceptible to multiple organ failure, sepsis, and mortality after trauma. Differences were not exclusively related to reproductive age and thus cannot be attributed to sex hormones alone. Females aged 16 to 44 years seem to tolerate shock better. Higher susceptibility to sepsis might be explained by male immune function or increased systemic burden from higher rates of surgical interventions.
BACKGROUND: Trauma team activation (TTA) represents a considerable expenditure of trauma centre resources. It is mainly triggered by field triage criteria. The overall quality of the criteria may be evaluated based on the rate of over- and undertriage. However, there is no gold standard that defines which adult patients truly require a trauma team. The objective of this study was to develop consensus-based criteria defining the necessity for a trauma team. METHODS: A consensus group was formed by trauma specialists experienced in emergency and trauma care with a specific interest in field triage and having previously participated in guideline development. A literature search was conducted to identify criteria that have already been used or suggested. The initial list of criteria was discussed in two Delphi round and two consensus conferences. The entire process of discussion and voting was highly standardized and extensively documented, resulting in a final list of criteria. RESULTS: Initially 95 criteria were identified. This was subsequently reduced to 20 final criteria to appropriately indicate the requirement for attendance of a trauma team. The criteria address aspects related to injury severity, admission to an intensive care unit, death within 24 h, need for specified invasive procedures, need for surgical and/or interventional radiological procedures, and abnormal vital signs within a defined time period. CONCLUSIONS: The selected criteria may be applied as a tool for research and quality control concerning TTA. However, future studies are necessary to further evaluate for possible redundancy in criteria that may allow for further reduction in criteria.
Errors are frequent in healthcare, but Emergency Departments are among the highest risk areas due to frequent changes in team composition, complexity and variety of cases, and difficulties encountered in managing multiple patients simultaneously.Crisis resource management (CRM) training has been associated with decreased error rates in the aviation industry as well as in certain areas of acute medical care, such as anesthesia and emergency medicine. In this study, we assessed whether a single day CRM training, combining didactic and simulation sessions, improves nontechnical skills (NTS) of interprofessional emergency medical teams.Seventy health professionals with different qualifications, working in an emergency department, were enrolled in the study. Twenty individual interprofessional teams were created. Each team was assessed before and after the training, through 2 in situ simulated exercises. The exercises were videotaped and were evaluated by 2 assessors who were blinded as to whether it was the initial or the final exercise. They used a new tool designed specifically for the assessment of emergency physicians' NTS. The intervention consisted of one-day training, combining didactic and simulation sessions, followed by an instructor facilitated debriefing. All participants went through this training after the initial assessment exercises.A significant improvement (P < 0.05) was shown for all the NTS assessed, in all professional categories involved, regardless of the duration of prior work experience in the Emergency Department.This study shows that even a short intervention, such as a single day CRM training, can have a significant impact in improving NTS, and can potentially improve patient safety.
Currently arbitrary, inconsistent and non-evidence-based age cutoffs are used in the literature to classify pediatric emergencies. None of these classifications have valid medical rationale. This leads to confusion and poor comparability of the different study results. To clarify this problem, this paper presents a systematic review of the commonly used age limits from 115 relevant articles. In the literature search 6226 articles were screened. To be included, the articles had to address the following three topics: "health services research in emergency medicine", "pediatrics" and "age as a differentiator". Physiologic and anatomic principles with reference to emergency medicine were used to solve the problem to create a medically based age classification for the first time.The Munich Age Classification System (MACS) presented in this paper is thus consistent with previous literature and is based on medical evidence. In the future, MAC should lead to ensure that a uniform classification is used. This will allow a better comparability of study results and enable meta-analyses across studies.
Medical care provided at the hospital emergency rooms in Germany has hardly been explored. On the occasion of restructuring the Municipal Hospital, the Munich City Council initiated the "Round Table Emergency Care" in order to determine reference figures for capacity planning. The present study was designed to analyze treatment data from 14 emergency departments which mainly carry the city's hospital emergency service. For inpatient cases, data were used in accordance with §21 Hospital Charges Act, for outpatient cases - as far as available - similar data were used, anonymized and combined with data from prehospital emergency medical services (EMS). In order to describe the domains treatment urgency, diagnostic/therapeutic effort and bed requirements, data were categorized in a 4-stage system. Over 12 months, 524,716 treatment cases were recorded: 34% were admitted to hospital, 80% came without EMS. One in 7 patients who independently went to an emergency room needed a bed in the intensive care or intermediate care unit (ICU/IMC). There were 64 cases per day and per 100,000 inhabitants requiring 7 ICU/IMC and 15 regular ward beds. Most cases (66%) were treated as outpatients and presented to the hospital's emergency department at times when facilities of the ambulatory care system would have been available. Urgency of these cases was usually low (50.9%), but effort was often high, due to diagnostics and surgical procedures. This study offers fundamental knowledge for planning emergency care. A large proportion of the presentations, especially those with injuries and those with diagnosis that require a more differentiated work-up, seem to be medically justified, which is why appropriate capacities have to be planned in. The study also shows that capacity planning on the basis of EMS cases alone is an inappropriate, one-sided approach.
BACKGROUND: Since the report "To err is human" was published by the Institute of Medicine in the year 2000, topics regarding patient safety and error management are in the focal point of interest of science and politics. Despite international attention, a structured and comprehensive medical education regarding these topics remains to be missing. GOALS: The Learning Objective Catalogue for Patient Safety described below the Committee for Patient Safety and Error Management of the German Association for Medical Education (GMA) has aimed to establish a common foundation for the structured implementation of patient safety curricula at the medical faculties in German-speaking countries. METHODS: The development the Learning Objective Catalogue resulted via the participation of 13 faculties in two committee meetings, two multi-day workshops, and additional judgments of external specialists. RESULTS: The Committee of Patient Safety and Error Management of GMA developed the present Learning Objective Catalogue for Patient Safety in Undergraduate Medical Education, structured in three chapters: Basics, Recognize Causes as Foundation for Proactive Behavior, and Approaches for Solutions. The learning objectives within the chapters are organized on three levels with a hierarchical organization of the topics. Overall, the Learning Objective Catalogue consists of 38 learning objectives. All learning objectives are referenced with the National Competency-based Catalogue of Learning Objectives for Undergraduate Medical Education. DISCUSSION: The Learning Objective Catalogue for Patient Safety in Undergraduate Medical Education is a product that was developed through collaboration of members from 13 medical faculties. In the German-speaking countries, the Learning Objective Catalogue should advance discussion regarding the topics of patient safety and error management and help develop subsequent educational structures. The Learning Objective Catalogue for Patient Safety can serve as a common ground for an intensified, constructive, subject-specific discussion about these topics at the medical faculties, and guide the implementation of hopefully multiple patient safety curricula in undergraduate medical education.
OBJECTIVE: Rising emergency medical services (EMS) utilisation increases transport to hospital emergency departments (ED). However, some patients receive outpatient treatment (discharged) while others are hospitalised (admitted). The aims of this analysis were to compare admitted and discharged cases, to assess whether cases that were discharged from the ED could be identified using dispatch data and to compare dispatch keyword categories and hospital diagnoses. DESIGN: Retrospective observational study using linked secondary data. SETTING AND PARTICIPANTS: 78 303 cases brought to 1 of 14 ED in the city of Munich, Germany, by EMS between 1 July 2013 and 30 June 2014. MAIN OUTCOME MEASURES: Characteristics of admitted and discharged cases were assessed. Logistic regression was used to estimate the association between discharge and age, sex, time of day, ambulance type and dispatch keyword category. Keyword categories were compared to hospital diagnoses. RESULTS: 39.4% of cases were discharged. They were especially likely to be young (OR 10.53 (CI 9.31 to 11.92), comparing <15-year-olds to >70-year-olds) and to fall under the categories 'accidents/trauma' (OR 2.87 (CI 2.74 to 3.01)) or 'other emergencies (unspecified)' (OR 1.23 (CI 1.12 to 1.34) (compared with 'cardiovascular'). Most frequent diagnoses came from chapter 'injury and poisoning' (30.1%) of the 10th revision of the international statistical classification of disease and related health problems (ICD-10), yet these diagnoses were more frequent at discharge (42.7 vs 22.0%) whereas circulatory system disease was less frequent (2.6 vs 21.8%). Except for accidents/trauma and intoxication/poisoning many underlying diagnoses were observed for the same dispatch keyword. CONCLUSION: Young age and dispatch for accidents or trauma were the strongest predictors of discharge. Even within the same dispatch keyword category the distribution of diagnoses differed between admitted and discharged cases. Discharge from the ED does not indicate that urgent response was unnecessary. However, these cases could be suitable for allocation to hospitals with low inpatient bed capacities and are of particular interest for future studies regarding the urgency of their condition.
BACKGROUND: Telemedical concepts, already successfully established in various clinical areas, such as radiology, are increasingly being implemented in the preclinical setting throughout Germany (tele-emergency physician). OBJECTIVE: The aim of the article is to present the objectives and requirements as well as the practical implementation and the potential indications for a telemedical emergency system in the preclinical situation. MATERIAL AND METHODS: Discussion of scientific facts and expert recommendations, specifically from experiences of the tele-emergency physician (Telenotarzt) project in an urban environment (City of Aachen). In addition, reference is made to a second pilot project in a rural region (Straubing, Bavaria). RESULTS: The successful implementation of a prehospital telemedical emergency system requires a specific framework, in particular of a legal and technical nature. In order to achieve optimal process quality it is important to establish a comprehensive concept that takes aspects of patient safety into account. The entire dispatch process in the control center as well as the training of all involved personnel must also be taken into consideration. CONCLUSION: With its special structures and processes, the overall concept of the telemedical emergency physician meets the changing challenges in the preclinical healthcare system and opens up new possibilities for patient care that meet the current requirements.
BACKGROUND: The future of emergency departments in Germany is influenced by increasing numbers of patients, demographic changes, new therapeutic concepts, current legislation and expert opinions. There is a lack of reliable data concerning the quantity and the type of injuries and diseases presenting in emergency departments. MATERIAL AND METHODS: This descriptive, epidemiological study included 14 emergency departments in Munich (1.41 million inhabitants in 2014), where 524,716 patients were treated from 1 July 2013 to 30 June 2014. 393,587 were included in this prospectively planned subgroup analysis. Patients presenting in special departments, such as gynecology or ophthalmology (59,523) or cases without a documented diagnosis (71,606) were excluded. Cases were assigned to the discipline trauma surgery or orthopedics according to the ICD-10 diagnosis chapters "injuries, poisoning and certain other consequences of external causes" and "diseases of the musculoskeletal system and connective tissue". RESULTS: Of the 393,587 cases included, 169,208 were treated due to trauma or orthopedic diseases (43%). 134,507 underwent outpatient treatment (79%) and 34,701 were admitted on the same day (21%). 29,920 patients suffered from head injuries (18%), 31,143 fractures (20%) and 24,367 deep wounds (14%) were recorded. On workdays between 8am and 10am, up to 47 patients per hour were treated and between 1pm and 3pm, up to 36 patients per hour. On weekends, most patients presented between 11am and 7pm. CONCLUSION: The present study analyzed the frequency of major diagnoses corresponding to the various medical disciplines including more than 500,000 patients. Of the emergency cases included, 43% were allocated to trauma surgery or orthopedics. These patients presented in the emergency departments around the clock and necessitate the permanent attendance of a trauma and emergency surgeon. Thereby, timely surgical care and decisions regarding indications for surgery and admission are ensured. Competence in trauma and emergency surgery is therefore essential for emergency departments.
Severe brain, thoracic and intrapelvic injuries, as well as heavy bleeding, are the main causes of death in patients with major trauma. Unstable pelvic ring fractures can cause this bleeding and the so-called "C problem". This is usually due to haemorrhagic shock caused by the loss of large volumes of blood from the presacral venous plexus, iliac vessels and the fracture surfaces. Many clinical studies have shown that, in the preclinical setting, unstable pelvic ring injuries are often underestimated. The application of a non-invasive external pelvic ring stabilisation (pelvic binder) is therefore recommended if a pelvic fracture is possible. Several circumferential pelvic binders have been developed and their prehospital use is increasing. Clinical and biomechanical studies have demonstrated that there is a favourable haemodynamic effect in unstable fractures, due to rapid closure of the pelvic ring. It is unclear whether the pelvic binder can be safely removed in a presumably haemodynamically stable patient. A correctly placed pelvic binder leads to anatomical closure of the pelvic ring. Therefore unstable pelvic ring fractures may be clinically and radiologically overlooked. This is a particular problem in unconscious patients. Furthermore, the real severity of the injury may then be underestimated in the diagnostic evaluation. Unconsidered opening of the pelvic binder can thus provoke renewed deterioration of the circulatory situation, especially if the injury was adequately treated by the binder and the C problem was controlled. The aim of this article is to describe procedures for handling pelvic binders, particularly as to how to deal with an already applied pelvic binder and how to "clear the pelvic region" while reducing the risk of haemodynamic instability. A detailed analysis of the literature and a Delphi-like discussion among several experts were performed. The following points were raised: 1) Assessment of the clinical situation, including trauma kinematics. 2) Assessment of the haemodynamic status. 3) Check of the need to open the pelvic binder for diagnostic/therapeutic measures before completing all diagnostic tests. 4) Assessment of the radiology diagnostic testing and release of the pelvic region. The result is a so-called "clear the pelvis algorithm" which describes a structured approach according to specific criteria and which specifies the circumstances under which the pelvic binder can be opened. Additional studies are necessary to analyse the applicability and safety of this algorithm in a clinical context. Our advice is not to "clear" the pelvis if no X-rays or CT scans of the pelvis have been carried out without (or with an opened) pelvic binder.
INTRODUCTION: A standardized team-training program for healthcare professionals in obstetric units was developed based on an analysis of common causes for adverse events found in claims registries. The interdisciplinary and inter-professional training concept included both technical and non-technical skill training. Evaluation of the program was carried out in hospitals with respect to the immediate personal learning of participants and also regarding changes in safety culture. METHODS: Trainings in n=7 hospitals including n=270 participants was evaluated using questionnaires. These were administered at four points in time to staff from participating obstetric units: (1) 10 days ahead of the training (n=308), (2) on training day before (n=239), (3) right after training (n=248), and (4) 6 months after (n=188) the intervention. Questionnaires included several questions for technical and non-technical skills and the Hospital Survey on Patient Safety (HSOPS). RESULTS: Strong effects were found in the participants' perception of their own competence regarding technical skills and handling of emergencies. Small effects could be observed in the scales of the HSOPS questionnaire. Most effects differed depending on professional groups and hospitals. CONCLUSIONS: Integrated technical and team management training can raise employees' confidence with complex emergency management skills and processes. Some indications for improvements on the patient safety culture level were detected. Furthermore, differences between professional groups and hospitals were found, indicating the need for more research on contributing factors for patient safety and for the success of crew resource management (CRM) trainings.
PURPOSE: Our aim was to develop new evidence-based and consensus-based recommendations for bleeding control in patients with multiple and/or severe injuries in the prehospital setting. This guideline topic is part of the 2022 update of the German Guideline on the Treatment of Patients with Multiple and/or Severe Injuries. METHODS: MEDLINE and Embase were systematically searched until June 2021. Further literature reports were obtained from clinical experts. Randomised controlled trials, prospective cohort studies, and comparative registry studies were included if they compared interventions for bleeding control in the prehospital setting using manual pressure, haemostatic agents, tourniquets, pelvic stabilisation, or traction splints in patients with multiple and/or severe injuries. We considered patient-relevant clinical outcomes such as mortality and bleeding control. Transfusion requirements and haemodynamic stability were surrogate outcomes. Risk of bias was assessed using NICE 2012 checklists. The evidence was synthesised narratively, and expert consensus was used to develop recommendations and determine their strength. RESULTS: Fifteen studies were identified. Interventions covered were pelvic binders (n = 4 studies), pressure dressings (n = 1), tourniquets (n = 6), traction splints (n = 1), haemostatic agents (n = 3), and nasal balloon catheters (n = 1). Fourteen new recommendations were developed. All achieved strong consensus. CONCLUSION: Bleeding control is the basic objective of treatment. This can be easily justified based on empirical evidence. There is, however, a lack of reliable and high-quality studies that assess and compare methods for bleeding control in patients with multiple and/or severe injuries. The guideline provides reasonable and practical recommendations (although mostly with a low grade of recommendation) and also reveals several open research questions that can hopefully be answered when the guideline is revised again.
INTRODUCTION: To improve the quality of criteria for trauma-team-activation it is necessary to identify patients who benefited from the treatment by a trauma team. Therefore, we evaluated a post hoc criteria catalogue for trauma-team-activation which was developed in a consensus process by an expert group and published recently. The objective was to examine whether the catalogue can identify patients that died after admission to the hospital and therefore can benefit from a specialized trauma team mostly. MATERIALS AND METHODS: between the 01/2007 and 12/2016 with a maximum abbreviated injury score (AIS) severity ≥ 2. The endpoint was hospital mortality, which was defined as death before discharge from acute care. RESULTS: dataset contains 18 of the 20 proposed criteria within the catalogue which identified 99.6% of the patients who were admitted to the trauma room following an accident and who died during their hospital stay. Moreover, our analysis showed that at least one criterion was fulfilled in 59,785 cases (79.1%). The average ISS in this group was 21.2 points (SD 9.9). None of the examined criteria applied to 15,828 cases (average ISS 8.6; SD 5). The number of consensus-based criteria correlated with the severity of injury and mortality. Of all deceased patients (8,451), only 31 (0.37%) could not be identified on the basis of the 18 examined criteria. Where only one criterion was fulfilled, mortality was 1.7%; with 2 or more criteria, mortality was at least 4.6%. DISCUSSION: The consensus-based criteria identified nearly all patients who died as a result of their injuries. If only one criterion was fulfilled, mortality was relatively low. However, it increased to almost 5% if two criteria were fulfilled. Further studies are necessary to analyse and examine the relative weighting of the various criteria. Our instrument is capable to identify severely injured patients with increased in-hospital mortality and injury severity. However, a minimum of two criteria needs to be fulfilled. Based on these findings, we conclude that the criteria list is useful for post hoc analysis of the quality of field triage in patients with severe injury.
PURPOSE: Trauma team activation (TTA) is thought to be essential for advanced and specialized care of very severely injured patients. However, non-specific TTA criteria may result in overtriage that consumes valuable resources or endanger patients in need of TTA secondary to undertriage. Consequently, criterion standard definitions to calculate the accuracy of the various TTA protocols are required for research and quality assurance purposes. Recently, several groups suggested a list of conditions when a trauma team is considered to be essential in the initial care in the emergency room. The objective of the survey was to post hoc identify trauma-related conditions that are thought to require a specialized trauma team that may be widely accepted, independent from the country's income level. METHODS: A set of questions was developed, centered around the level of agreement with the proposed post hoc criteria to define adequate trauma team activation. The participants gave feedback before they answered the survey to improve the quality of the questions. The finalized survey was conducted using an online tool and a word form. The income per capita of a country was rated according to the World Bank Country and Lending groups. RESULTS: The return rate was 76% with a total of 37 countries participating. The agreement with the proposed criteria to define post hoc correct requirements for trauma team activation was more than 75% for 12 of the 20 criteria. The rate of disagreement was low and varied between zero and 13%. The level of agreement was independent from the country's level of income. CONCLUSIONS: The agreement on criteria to post hoc define correct requirements for trauma team activation appears high and it may be concluded that the proposed criteria could be useful for most countries, independent from their level of income. Nevertheless, more discussions on an international level appear to be warranted to achieve a full consensus to define a universal set of criteria that will allow for quality assessment of over- and undertriage of trauma team activation as well as for the validation of field triage criteria for the most severely injured patients worldwide.
BACKGROUND: The human external cargo (HEC) operations conducted by Helicopter Emergency Medical Services (HEMS) rarely take place at night, making it difficult for crew members to attain and maintain the level of expertise needed to perform winch operations in the dark. As EASA requirements for training cannot currently be met, we evaluated whether simulation training could be an option. METHODS: This paper reports on a training concept using indoor simulation for the training of nighttime HEC operations. Participants' experience and perceptions were evaluated with a survey and the procedural and economic advantages of the simulation approach were compared with those of the usual outdoor HEC training. RESULTS: Most participants had limited exposure to real-life nighttime HEC missions before undergoing the simulation-based training. The frequency of training cycles in simulation was much higher compared to conventional training (60 cycles indoors vs. 20 outdoors for HEMS-TC, 20 cycles indoors vs. 4 outdoors for MCM). Trainees perceived that their technical and non-technical skills (NTS) improved with the training. The estimated costs of standard outdoor-based nighttime HEC training (138€ per cycle) are at least 6.5 times higher than the costs of indoor simulated training (approximately 21€ per cycle). With a change to simulation, carbon dioxide emissions could potentially be reduced by more than 35 tons. CONCLUSIONS: Indoor simulation training of night HEC operations has advantages with regard to cost-effectiveness, environmental friendliness, and self-reported improvements in skills and knowledge. Its use is feasible and could improve crew and patient safety and fulfill regulatory demands for training intensity.
BACKGROUND: With the aging population, the number of geriatric trauma patients continues to rise, posing significant challenges for emergency care and trauma management. Structured trauma team activation (TTA) protocols aim to provide timely and adequate treatment for severely injured patients. However, evidence suggests that current triage criteria may inadequately address the specific needs of geriatric patients, potentially leading to undertriage and worse outcomes. METHODS: The prospective, multicentre observational cohort study analysed trauma team activation and triage practices for patients aged ≥ 70 years across 12 Level 1 trauma centres across rural and urban regions in Germany and Switzerland. Data were prospectively collected from December 2020 to February 2021, following the STROBE guidelines. Triage decisions were compared with the TAcTIC (Trauma Team Activation and Trauma/Injury Care) consensus criteria to assess undertriage and overtriage rates. Key outcomes included trauma team activation rates, injury severity, transport characteristics, and early mortality. RESULTS: Among 3,753 trauma patients, 1,371 (36.5%) were geriatric (≥ 70 years). Trauma team activation was significantly lower in the geriatric group (15.8%) compared to younger patients (31.8%), despite similar injury severity. Post-hoc analysis revealed that 53.8% of geriatric patients requiring trauma care were undertriaged. Head injuries (47.7%) and pelvic fractures (5.7%) were more common in geriatric patients in comparison to the younger cohort. Mortality within 48 h was more than three times as high in geriatric patients (1.8% vs. 0.5%). CONCLUSION: A significant undertriage rate (53.8%) was identified among geriatric trauma patients, contributing to delayed care and increased mortality. Undertriage of geriatric trauma patients remains a critical issue, reflecting the insufficiency of current trauma activation protocols. Tailored triage criteria that even more consider age-related physiological differences, comorbidities, and frailty are urgently needed. Future updates to trauma guidelines should aim to reduce undertriage and improve outcomes for this vulnerable population. CLINICAL TRIAL NUMBER: Not applicable.
Simulation educators are often requested to provide multidisciplinary and/or interprofessional simulation training in response to critical incidents. Current perspectives on patient safety focus on learning from failure, success and everyday variation. An international collaboration has led to the development of an accessible and practical framework to guide the implementation of appropriate simulation-based responses to clinical events, integrating quality improvement, simulation and patient safety methodologies to design appropriate and impactful responses. In this article, we describe a novel five-step approach to planning simulation-based interventions after any events that might prompt simulation-based learning in healthcare environments. This approach guides teams to identify pertinent events in healthcare, involve relevant stakeholders, agree on appropriate change interventions, elicit how simulation can contribute to them and share the learning without aggravating the second victim phenomenon. The framework is underpinned by Deming's System of Profound Knowledge, the Model for Improvement and translational simulation. It aligns with contemporary socio-technical models in healthcare, by emphasising the role of clinical teams in designing adaptation and change for improvement, as well as encouraging collaborations to enhance patient safety in healthcare. For teams to achieve this adaptive capacity that realises organisational goals of continuous learning and improvement requires the breaking down of historical silos through the creation of an infrastructure that formalises relationships between service delivery, safety management, quality improvement and education. This creates opportunities to learn by design, rather than chance, whilst striving to close gaps between work as imagined and work as done.
