[Development of ground-based physician-staffed emergency missions in the city of Leipzig from 2003 to 2013]

A retrospective analysis of the need for on-site emergency physician presence and mission characteristics of a rural ground-based emergency medical service

BACKGROUND

This study aimed to address the challenges faced by rural emergency medical services in Europe, due to an increasing number of missions and limited human resources. The primary objective was to determine the necessity of having an on-site emergency physician (EP), while the secondary objectives included analyzing the characteristics of rural EP missions.

METHODS

A retrospective study was conducted, examining rural EP missions carried out between January 1st, 2017, and December 2nd, 2021 in Burgenland, Austria. The need for physical presence of an EP was classified based on the National Advisory Committee for Aeronautics (NACA) score into three categories; category A: no need for an EP (NACA 1-3); category B: need for an EP (NACA 1-3 along with additional medical interventions beyond the capabilities of emergency medical technicians); and category C: definite need for an EP (NACA 4-7). Descriptive statistics were used for analysis.

RESULTS

Out of 16,971 recorded missions, 15,591 were included in the study. Approximately 32.3% of missions fell into category A, indicating that an EP's physical presence was unnecessary. The diagnoses made by telecommunicators matched those of the EPs in only 52.8% of cases.

CONCLUSION

The study suggests that about a third of EP missions carried out in rural areas might not have a solid medical rationale. This underscores the importance of developing an alternative care approach for these missions. Failing to address this could put additional pressure on already stretched EMS systems, risking their collapse.

[Frequency and characteristics of interventions by community paramedics on people in need of care : Analysis of 2,410 deployment protocols for people aged 65+ years]

BACKGROUND

The aim of this study was to obtain a differentiated view of interventions delivered by community paramedics (Gemeindenotfallsanitäter, G‑NFS) in older people in need of care living in nursing homes and at home.

MATERIALS AND METHODS

A retrospective analysis of G‑NFS documentation from 2021 with a focus on patients aged ≥65 years was performed. Data were grouped into callouts to nursing homes or private homes. Interventions, urgency, transport, and further recommendations were analyzed descriptively.

RESULTS

Of 5,900 G-NFS protocols, 43.0% (n = 2,410) were related to elderly people (mean age 80.8 years, 49.7% female). A total of 20.6% of these callouts involved nursing home residents, 38.4% (n = 926) were homecare patients, and 41% (n = 988) of callouts were to persons who did not rely on care. No specific interventions except advice were given to 48.4% of nursing home residents, and to even 82.1% of those in homecare and 83.7% of those without care needs. About 60% of the G‑NFS interventions were classified as non-urgent. Transport was waived for 63.1% of nursing home residents, for 58.1% in homecare, and for 60.6% of persons without care needs. A visit to the emergency department was recommended to 29.4% of nursing home residents, 37.6% of homecare patients, and 33.6% of persons without need of care. Measures related to urine catheters were documented much more often in nursing homes (38.5%) than in patients in homecare (15.1%) or without need of care (9.3%).

CONCLUSION

Community paramedics perform primary care tasks and can contribute to a reduction in unnecessary transport. It should be discussed whether the emergency medical service is responsible for such interventions and how older people in need of care can be cared for according to their needs in the future.

Digital transition in rural emergency medicine: Impact of job satisfaction and workload on communication and technology acceptance

BACKGROUND

Tele-emergency physicians (TEPs) take an increasingly important role in the need-oriented provision of emergency patient care. To improve emergency medicine in rural areas, we set up the project 'Rural|Rescue', which uses TEPs to restructure professional rescue services using information and communication technologies (ICTs) in order to reduce the therapy-free interval. Successful implementation of ICTs relies on user acceptance and knowledge sharing behavior.

METHOD

We conducted a factorial design with active knowledge transfer and technology acceptance as a function of work satisfaction (high vs. low), workload (high vs. low) and point in time (prior to vs. after digitalization). Data were collected via machine readable questionnaires issued to 755 persons (411 pre, 344 post), of which 304 or 40.3% of these persons responded (194 pre, 115 post).

RESULTS

Technology acceptance was higher after the implementation of TEP for nurses but not for other professions, and it was higher when the workload was high. Regarding active communication and knowledge sharing, employees with low work satisfaction are more likely to share their digital knowledge as compared to employees with high work satisfaction. This is an effect of previous knowledge concerning digitalization: After implementing the new technology, work satisfaction increased for the more experienced employees, but not for the less experienced ones.

CONCLUSION

Our research illustrates that employees' workload has an impact on the intention of using digital applications. The higher the workload, the more people are willing to use TEPs. Regarding active knowledge sharing, we see that employees with low work satisfaction are more likely to share their digital knowledge compared to employees with high work satisfaction. This might be attributed to the Dunning-Kruger effect. Highly knowledgeable employees initially feel uncertain about the change, which translates into temporarily lower work satisfaction. They feel the urge to fill even small knowledge gaps, which in return leads to higher work satisfaction. Those responsible need to acknowledge that digital change affects their employees' workflow and work satisfaction. During such times, employees need time and support to gather information and knowledge in order to cope with digitally changed tasks.

Zwischen Notfall und Fehleinsatz – eine retrospektive Analyse der Einsätze eines Notarzteinsatzfahrzeugs in Frankfurt am Main von 2014 bis 2019

Hintergrund

Ein steigendes Einsatzaufkommen lässt sich sowohl im Rettungsdienst als auch im notärztlichen System in Deutschland verzeichnen. Oft werden dabei Fehleinsätze durch leicht erkrankte/verletzte Patienten als wachsende Problematik vermutet. Die vorliegende Untersuchung überprüft die Hypothese von steigenden Einsatzzahlen mit gleichzeitiger Zunahme von gegebenenfalls nichtindizierten Einsätzen.

Material und Methoden

Es erfolgte eine retrospektive Analyse der notärztlichen Einsätze des an der Universitätsklinik Frankfurt am Main stationierten Notarzteinsatzfahrzeugs von 2014 bis 2019. Die Analyse berücksichtigt zudem Faktoren wie die notärztliche Tätigkeit, Behandlungspriorität, Alarmierungsart und das Patientenalter.

Ergebnisse

Im beobachteten Zeitraum lässt sich ein Anstieg der notärztlichen Einsatzzahlen um mehr als 20 % erkennen. Der größte Anstieg zeigt sich bei Einsätzen, bei denen keine notärztliche Tätigkeit (+80 %) notwendig war. Einsätze der niedrigsten Behandlungspriorität (+61 %) sowie der höchsten Behandlungspriorität (+61 %) nahmen ebenfalls signifikant zu.

Diskussion

Die vorliegenden Zahlen stützen die Hypothese, dass bei signifikant gesteigertem Einsatzaufkommen mehr Einsätze durch den Notarzt bewältigt werden müssen, bei denen er rückblickend nicht notwendig gewesen wäre. Trotzdem gibt es auch mehr Patienten, die einen sofortigen Arztkontakt benötigen. Die hieraus resultierende erhöhte Einsatzfrequenz kann zu einer erhöhten Belastung sowie erschwerten zeitgerechten Disposition der notärztlichen Ressource führen.

Hospital Emergency Departments—Utilization and Resource Deployment in the Hospital as a Function of the Type of Referral

BACKGROUND

Inpatient admission rates and the resources required upon admission to the hospital were studied as a function of the type of referral to the emergency department (ED) of a university hospital.

METHODS

We retrospectively analyzed data concerning patients who were treated in the ED of the University of Leipzig Medical Center in 2019. The following data were recorded: process data, type of referral, hospital admission vs. discharge from the ED, and leading symptom according to classification as "trauma" or "non-trauma." For all admitted patients, the Patient Clinical Complexity Level (PCCL), length of hospital stay, and intensive care (yes/no) with or without ventilation were recorded.

RESULTS

Data on 34 178 patients (50.9 ± 22.2 years, 53.8% male) were analyzed; 28.8% of patients were referred because of "trauma," and the remaining 71.2% for "non trauma". The most common sources of referral were the rescue and emergency medical services (47.7%) and the patients themselves (self-referrals, 44.7%); 7.6% of the patients were referred by a resident doctor or general practitioner (physician). 62.6% were discharged from the ED after diagnosis and treatment, while 37.4% were admitted to the hospital. In comparison with self-referred patients as a baseline, the likelihood of inpatient admission was higher when the patient was referred by a physician (adjusted odds ratio [OR] 2.2), by the emergency rescue service without an emer - gency physician (OR 3.4), by an emergency physician (OR 9.3), or by the helicopter rescue service (OR 44.1). 49.1% of patients with trauma referred themselves to the ER, and 36% were referred by the emergency rescue service. Older and male patients were more likely to be admitted to the hospital, especially for non-trauma. 30.4% of the admitted patients required intensive care, and 35.5% of the patients in intensive care required ventilation.

CONCLUSION

Whether a patient is admitted to the hospital depends on the source of the referral and the leading symptom on arrival in the ED. One in every six self-referred patients is admitted to the hospital, particularly when the reason for presenting to the ER is non-traumatic and some of them go on to receive intensive care. The high percentage (around 95%) of self-referred trauma patients that are discharged from the ED presumably indicates that they were referred mainly for the exclusion of dangerous conditions, and/or that appropriate care options are lacking in the community setting.

[Educational perspectives in emergency paramedicine : Interdisciplinary discourse on education, professional practice, and challenges in the field of emergency medical services]

Societal developments that result in an increase in geriatric, psychosocial, and subacute (i.e. not time-critical) emergencies are changing the demands on emergency care and posing challenges to the system of emergency care and emergency medical services (EMS). The training of emergency paramedics (NotSan) lays the foundation for finding a qualified systemic response to evolving patient needs and requirements. By extending and strengthening their competencies, NotSan are to be understood as basic emergency care providers. Their training should therefore be further developed in terms of evidence-based and patient-centered care in order to increase their competency to act and to achieve demand-oriented holistic (outpatient) care. New EMS resources such as community paramedics (GNFS) and telemedical support systems offer opportunities to strengthen competencies in patient care. The guiding principles of care should be patient safety and patient centeredness. In addition to increasing the basic competencies and equipment of existing EMS resources as well as continuous training opportunities, innovative cross-sectoral and cross-professional care concepts are necessary and must be supported.

[Care of older patients by community emergency paramedics : Comparison of community-dwellers and nursing home residents]

Hintergrund

Notaufnahmen und Rettungsdienste werden zunehmend durch nicht vital bedrohlich erkrankte Patienten belastet. Ein großer Anteil der Rettungsdiensteinsätze entfällt auf ältere Menschen. Um eine unnötige Disponierung höherwertiger Rettungsmittel zu reduzieren, wurde das Modellprojekt Gemeindenotfallsanitäter (G-NFS) entwickelt.

Ziel der Arbeit

Ziel dieser Arbeit war es herauszufinden, ob sich spezifische Einsatzschwerpunkte des G‑NFS in der Versorgung älterer Menschen in häuslicher Umgebung und im Pflegeheim zeigen.

Material und Methoden

Es handelt sich um eine retrospektive Beobachtungsstudie auf Basis der Einsatzdokumentation vom 01.07.2019 bis zum 30.06.2020. Es wurden G‑NFS Einsätze bei älteren Menschen (≥ 65 Jahre) analysiert, unterteilt nach den Einsatzorten Pflegeheim oder Häuslichkeit.

Ergebnisse

Es wurden 2358 Protokolle ausgewertet (Durchschnittsalter: 80,8 Jahre; 52,9 % weiblich). Vor Ort wurden 55 % der Patienten versorgt. Die durchgeführten Maßnahmen umfassten Beratungsgespräche (79,4 %), Hilfe bei Selbstmedikation (16,7 %) und Medikamentengabe (23,2 %). Auf Pflegeheimbewohner entfielen 329 (14,0 %) Einsätze. Maßnahmen in Bezug auf Urindauerkatheter wurden häufiger bei Pflegeheimbewohnern als in der Häuslichkeit durchgeführt (32,2 % bzw. 5,7 % aller Einsätze). Bei Patienten mit Katheterproblemen erfolgte im Vergleich zu anderen Einsätzen nahezu immer eine Versorgung vor Ort (84,3 % bzw. 52,2 %).

Diskussion

Durch G‑NFS können die Mehrzahl der älteren Patienten ambulant versorgt und andere Ressourcen entlastet werden. Allerdings führen G‑NFS auch Maßnahmen durch, die im Verantwortungsbereich der hausärztlichen Versorgung liegen, und gleichen somit strukturelle Defizite in der medizinisch-pflegerischen Versorgung aus.

Alters- und geschlechtsbezogene Verteilung von Zuführung, Ersteinschätzung, Entlassart und Verweildauer in der zentralen Notaufnahme

Einleitung

Jährlich stellen sich bundesweit zahlreiche Patienten in zentralen Notaufnahmen vor. Ziel der vorliegenden Untersuchung war es, alters- und geschlechtsabhängig Zuführung, Ersteinschätzung, Entlassart und Verweildauer an einem universitären Standort zu analysieren.

Material und Methodik

In dieser retrospektiven Studie wurden alle Patientenkontakte der zentralen Notaufnahme des Universitätsklinikums Düsseldorf des Jahres 2019 erfasst und anhand der Prozesskriterien Zuführung, Ersteinschätzung, Entlassart und Verweildauer kategorisiert und deren Verteilung untersucht.

Ergebnisse

Vom 01.01. bis 31.12.2019 wurden insgesamt 43.821 Patientenkontakte erfasst. Das durchschnittliche Alter der Patienten betrug 47 ± 24 Jahre (Median: 47, Min.–Max.: 0–106). Der Anteil weiblicher Patienten betrug 48 %. Ein Alter ≤ 17 Jahren wiesen 10 % der Patienten (♀ vs. ♂: 4 vs. 6 %, p < 0,0001) und ein Alter ≥ 70 Jahre 24 % auf (♀ vs. ♂: 13 vs. 11 %, p < 0,0001). Für beide Geschlechter nahm der Anteil der Triagekategorien „blau“ und „grün“ über die aufsteigenden Altersgruppen stetig ab. Ab der Altersgruppe der 50- bis 59-Jährigen lag für beide Geschlechter führend eine höhere Dringlichkeit („gelb“ bis „rot“) vor. Während im Alter ≤ 17 Jahren mit 84–90 % vorwiegend eine ambulante Behandlung erfolgte, reduzierte sich dieser Anteil über die weiteren Altersgruppen bis auf 22 % bei Männern und 28 % bei Frauen in der Altersgruppe der ≥ 90-Jährigen. Für die drei Entlassarten „ambulant“, „prästationär“ und „stationär“ stieg die Verweildauer bei beiden Geschlechtern mit dem Alter kontinuierlich an.

Schlussfolgerung

Es finden sich deutliche und vor allem altersabhängige Unterschiede in den Prozesskriterien Zuführung, Ersteinschätzung, Entlassart und Verweildauer. Rund 15 % der Patienten sind kritisch krank oder verletzt („orange“ und „rot“). Mit steigendem Alter nimmt der Anteil dieser Triagekategorien zu. Bei rund 30 % der Patienten besteht eine stationäre Aufnahmeindikation, entsprechende Bettenkapazitäten müssen täglich eingeplant werden.

Implementation of a full-scale prehospital telemedicine system: evaluation of the process and systemic effects in a pre-post intervention study

OBJECTIVES

To review the implementation strategy from a research project towards routine care of a comprehensive mobile physician-staffed prehospital telemedicine system. The objective is to evaluate the implementation process and systemic influences on emergency medical service (EMS) resource utilisation.

DESIGN

Retrospective pre-post implementation study.

SETTING

Two interdisciplinary projects and the EMS of a German urban region.

INTERVENTIONS

Implementation of a full-scale prehospital telemedicine system.

ENDPOINTS

Descriptive evaluation of the implementation strategy. Primary endpoint: ground-based and helicopter-based physician staffed emergency missions before and after implementation.

RESULTS

The first research project revealed positive effects on guideline adherence and patient safety in two simulation studies, with feasibility demonstrated in a clinical study. After technical optimisation, safety and positive effects were demonstrated in a multicentre trial. Routine care in the city of Aachen, Germany was conducted stepwise from April 2014 to March 2015, including modified dispatch criteria. Systemic parameters of all EMS assignments between pre-implementation (April 2013 to March 2014) and post implementation (April 2015 to March 2016): on-scene EMS physician operations decreased from 7882/25 187 missions (31.3%) to 6360/26 462 (24.0%), p<0.0001. The need for neighbouring physician-staffed units dropped from 234/25 187 (0.93%) to 119/26 462 (0.45%), p<0.0001, and the need for helicopter EMS from 198/25 187 (0.79%) to 100/26 462 (0.38%), p<0.0001. In the post implementation period 2347 telemedical interventions were conducted, with 26 462 emergency missions (8.87%).

CONCLUSION

A stepwise implementation strategy allowed transfer from the project phase to routine care. We detected a reduced need for conventional on-scene physician care by ground-based and helicopter-based EMS, but cannot exclude unrecognised confounders, including modified dispatch criteria and possible learning effects. This creates the potential for increased availability of EMS physicians for life-threatening emergencies by shifting physician interventions from conventional to telemedical care.

Entwicklung der Frequenz und des Spektrums von Rettungsdiensteinsätzen in Deutschland

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.

Comparing the diagnostic concordance of tele-EMS and on-site-EMS physicians in emergency medical services: a retrospective cohort study

In 2014, a telemedicine system was established in 24-h routine use in the emergency medical service (EMS) of the city of Aachen. This study tested whether the diagnostic concordance of the tele-EMS physician reaches the same diagnostic concordance as the on-site-EMS physician. The initial prehospital diagnoses were compared to the final hospital diagnoses. Data were recorded retrospectively from the physicians' protocols as well as from the hospital administration system and compared. Also, all diagnostic misconcordance were analysed and reviewed in terms of logical content by two experts. There were no significant differences between the groups in terms of demographic data, such as age and gender, as well as regarding the hospital length of stay and mortality. There was no significant difference between the diagnostic concordance of the systems, except the diagnosis "epileptic seizure". Instead, in these cases, "stroke" was the most frequently chosen diagnosis. The diagnostic misconcordance "stroke" is not associated with any risks to patients' safety. Reasons for diagnostic misconcordance could be the short contact time to the patient during the teleconsultation, the lack of personal examination of the patient by the tele-EMS physician, and reversible symptoms that can mask the correct diagnosis.

[System and skill utilization in an Austrian emergency physician system: retrospective study]

BACKGROUND

The continuous rise in calls for emergency physicians and the low proportion of indicated missions has led to a loss of job attractiveness, which in turn renders services in some areas unable to sufficiently staff units. This retrospective analysis evaluated the frequency of emergency and general medical interventions in a ground-based emergency physician response system.

METHODS

A retrospective analysis of anonymized data from the electronic documentation system of the emergency physician response unit at the Medical University of Graz was carried out. Calls answered by emergency physicians between 2010 and 2018 were extracted, measures carried out were evaluated and categorized into three groups: specific emergency interventions (category I), general medical interventions (category II) and no medical activity (category III). The frequency of occurrence of these categories was compared and incidences of individual measures per 100,000 inhabitants were calculated.

RESULTS

A total of 15,409 primary responses and 322 secondary transports were extracted and analyzed. The annual rate of system activation rose almost continuously from 1442 calls in 2010 to 2301 calls in 2018. The 3687 (23.4%) cancellations resulted in 12,044 patient contacts. Of these, 2842 (18%) calls were coded as category I, 7372 (47%) as category II and 5518 (35%) as category III. The frequency of specific emergency measures and general medical interventions was estimated at 157/100,000 and 409/100,000 inhabitants, respectively.

CONCLUSIONS

No specific emergency physician interventions were required in the majority of call-outs. The current model of preclinical care does not appear to be patient-oriented and efficient. Furthermore, the low proportion of critically ill and injured patients already leads to a reduction in attractiveness for emergency physicians and may introduce the threat of quality issues due to insufficient routine experience and lack of training.

Sublingual microcirculation in prehospital critical care medicine: A proof-of-concept study

OBJECTIVE

Diagnostic and risk stratification are limited in emergencies. The measurement of microcirculation might identify patients with poor perfusion but compensated macrocirculation such as in beginning shock. This proof-of-concept study examines whether sublingual prehospital sidestream dark-field microscopy is feasible.

METHODS

This prospective observational study included patients receiving medical aid by an emergency ambulance who had a spontaneous circulation and offered access to the sublingual mucosa. Sublingual measurement of microcirculation was performed using a sidestream dark field camera. Video quality was evaluated with microcirculation image quality score (microcirculation image quality score). AVA 4.3C software calculated microcirculatory parameters.

RESULTS

Thirty patients (47% male) were included. The average age was 63 years (±20 years SD), the severity of the disease (quantified by National Advisory Committee on Aeronautics) was 3.4 (±0.7 SD). Macrocirculation presented within the normal range. The most frequent cause preventing the measurement was a time-critical disease (64%). In 17 patients (57%), the videos could be analyzed immediately. The average quality of the video was 2.2 ± 0.45 points ('acceptable'). There were minor restrictions of microcirculation. Microcirculation correlated with National Advisory Committee on Aeronautics, but not with the macrocirculation. No complications occurred.

CONCLUSION

The prehospital sublingual measurement is safe and valid. Despite normal macrocirculation, microcirculation was impaired and correlated with National Advisory Committee on Aeronautics.

Evaluation of a Rural Emergency Medical Service Project in Germany: Protocol for a Multimethod and Multiperspective Longitudinal Analysis

BACKGROUND

German emergency medical services are a 2-tiered system with paramedic-staffed ambulances as the primary response, supported by prehospital emergency doctors for life-threatening conditions. As in all European health care systems, German medical practitioners are in short supply, whereas the demand for timely emergency medical care is constantly growing. In rural areas, this has led to critical delays in the provision of emergency medical care. In particular, in cases of cardiac arrest, time is of the essence because, with each passing minute, the chance of survival with good neurological outcome decreases.

OBJECTIVE

The project has 4 main objectives: (1) reduce the therapy-free interval through widespread reinforcement of resuscitation skills and motivating the public to provide help (ie, bystander cardiopulmonary resuscitation), (2) provide faster professional first aid in addition to rescue services through alerting trained first aiders by mobile phone, (3) make more emergency physicians available more quickly through introducing the tele-emergency physician system, and (4) enhance emergency care through improving the cooperation between statutory health insurance on-call medical services (German: Kassenärztlicher Bereitschaftsdienst) and emergency medical services.

METHODS

We will evaluate project implementation in a tripartite prospective and intervention study. First, in medical evaluation, we will assess the influences of various project measures on quality of care using multiple methods. Second, the economic evaluation will mainly focus on the valuation of inputs and outcomes of the different measures while considering various relevant indicators. Third, as part of the work and organizational analysis, we will assess important work- and occupational-related parameters, as well as network and regional indexes.

RESULTS

We started the project in 2017 and will complete enrollment in 2020. We finished the preanalysis phase in September 2018.

CONCLUSIONS

Overall, implementation of the project will entail realigning emergency medicine in rural areas and enhancing the quality of medical emergency care in the long term. We expect the project to lead to a measurable increase in medical laypersons' individual motivation to provide resuscitation, to strengthen resuscitation skills, and to result in medical laypersons providing first aid much more frequently. Furthermore, we intend the project to decrease the therapy-free interval in cases of cardiac arrest by dispatching first aiders via mobile phones. Previous projects in urban regions have shown that the tele-emergency physician system can provide a higher availability and quality of emergency call-outs in regular health care. We expect a closer interrelation of emergency practices of statutory health insurance physicians with the rescue service to lead to better coordination of rescue and on-call services.

[Preclinical emergency anesthesia : A current state analysis from 2015-2017]

BACKGROUND AND OBJECTIVE

Due to multiple factors the performance of preclinical emergency anesthesia is fraught with risks even for experienced emergency physicians. In order to support emergency physicians in monitoring and management of anesthesia, the German practice management guidelines for preclinical emergency anesthesia in adults were published in 2015; however, current data on adherence to the guidelines are not available.

MATERIAL AND METHODS

In a retrospective register analysis of preclinical anesthesia from 2015-2017 in Baden-Württemberg, the recorded anesthetic agents, monitoring, airway management and medical disciplines of emergency physicians were analyzed. The anesthetic agents utilized were compared to the emergency scenarios in the guidelines (e.g. cardiac patients, patients with acute respiratory insufficiency or acute neurological disorder and trauma patients).

RESULTS

Midazolam and propofol were predominantly used in the 12,605 cases of preclinical emergency anesthesia evaluated. The adherence to the guidelines was 35% for cardiac patients, 51% for patients with acute respiratory insufficiency or 52% for acute neurological disorders and 79% for trauma patients. Securing the airway was carried out in 88.5 % with endotracheal intubation (capnography 79%). Discipline-related differences occurred in airway management for the devices used, capnography, muscle relaxation and the frequency of the subjectively difficult airway. A higher adherence for trauma patients and patients with acute neurological disorders was found for emergency physicians who were anesthesiologists compared to non-anesthesiologists.

CONCLUSION

The study of the current state of preclinical emergency anesthesia in Germany showed a deficient implementation of the pharmacological recommendations for action except for trauma patients. Reasons for divergence could arise due to different availability of rescue equipment, training concepts or discipline of emergency physicians. Suitable education and training could improve the quality of prehospital anesthesia in Germany.
