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

Expectations of healthcare professionals of community-based telemedicine in emergency medical service

BACKGROUND

In times of demographic change and an immense shortage of qualified personnel in emergency medical services, telemedicine could offer more efficient solutions for better care. Given the community-based nature of emergency services, local communities play an important role. This study explored the expectations of healthcare professionals and volunteers for telemedicine tools in prehospital emergency medicine.

METHODS

This mixed-methods study was conducted in the rural region of Burgenland in Austria with stakeholders of the local emergency medical service in two focus groups (13 participants) and 99 quantitative questionnaires.

RESULTS

Combining quantitative and qualitative data, we found that a majority of respondents (almost 80%) already experienced basic telemedicine and consider it valuable. In particular, there is a strong expectation for diagnostic support and inquiries related to potential hospitalization. Findings from two focus groups emphasized the importance of cultivating an improved learning culture, developing a specific mindset, and refining soft skills. The optimal telemedicine solution includes a knowledgeable and experienced tele-emergency physician coupled with user-friendly technology.

CONCLUSION

To be clear about the expectations of stakeholders, it is essential to involve all stakeholders right from the beginning. The solution should prioritize the integration of existing structures and be seamlessly incorporated into an evolving learning culture, while also fostering the necessary mindsets alongside educational aspects.

Improving the Care of Severe, Open Fractures and Postoperative Infections of the Lower Extremities: Protocol for an Interdisciplinary Treatment Approach

BACKGROUND

Patients with open fractures often experience complications during their injury. The treatments incur high costs. Interdisciplinary cooperation between different medical disciplines may improve treatment outcomes. Such cooperation has not yet been envisaged in the German health care system.

OBJECTIVE

The aim of the study is to improve the treatment of fractures with open soft tissue damage or postoperative complications in terms of duration and sustainability in a region in northwest Germany. Largely standardized diagnostics and therapy are intended to optimize processes in hospitals. In addition, a reduction in the duration of treatment and treatment costs is to be achieved.

METHODS

Using a digital platform, physicians from 31 hospitals present patient cases to an interdisciplinary group of experts from the fields of plastic surgery, infectiology, hygiene, and others. The group of experts from the environment of the University Hospital Münster promptly makes a joint treatment recommendation for the individual case. The plan is to examine 3300 patients with open fractures or surgical complications. As consortium partners, there are also 3 statutory health insurance companies. The extent to which the therapy recommendations are effective and contribute to cost reduction in the health care system will be empirically investigated in a stepped-wedge cluster-randomized design. In addition, medical and nonmedical professional groups involved in the project will be asked about their work in the project (in total, 248 clinic employees). The primary outcome is the complication rate of open fractures or the occurrence of postoperative complications. As secondary outcomes, the number of antibiotics administered, limb function, and quality of life will be assessed. The health economic evaluation refers to the costs of health services and absenteeism. For the work-related evaluation, workload, work engagement, work-related resources, readiness for technology, and ergonomic aspects of the new telemedical technology will be collected. In addition, clinic employees will give their assessments of the success of the project in a structured telephone interview based on scaled and open-ended questions.

RESULTS

The project started in June 2022; data collection started in April 2023. As of mid-June 2024, data from 425 patients had been included. In total, 146 members of staff had taken part in the questionnaire survey and 15 had taken part in the interviews.

CONCLUSIONS

Standardized treatment pathways in the standard care of patients with open fractures and postoperative infections will be established to reduce complications, improve chances of recovery, and reduce costs. Unnecessary and redundant treatment steps will be avoided through standardized diagnostics and therapy. The interdisciplinary treatment perspective allows for a more individualized therapy. In the medium term, outpatient or inpatient treatment centers specialized in the patient group could be set up where the new diagnostic and therapeutic pathways could be competently applied.

Long-term effects of a prehospital telemedicine system on structural and process quality indicators of an emergency medical service

The benefits of a telemedical support system for prehospital emergency medical services include high-level emergency medical support at the push of a button: delegation of drug administration, diagnostic assistance, initiation of therapeutic measures, or choice of hospital destination. At various European EMS sites telemedical routine systems are shortly before implementation. The aim of this study was to investigate the long-term effects of implementing a tele-EMS system on the structural and procedural quality indicators and therefore performance of an entire EMS system. This retrospective study included all EMS missions in Aachen city between 2015 and 2021. Regarding structural indicators of the EMS system, we investigated the overall number of emergency missions with tele-EMS and onsite EMS physicians. Furthermore, we analyzed the distribution of tracer diagnosis and process quality with respect to the time spans on the scene, time until teleconsultation, duration of teleconsultation, prehospital engagement time, and number of simultaneous teleconsultations. During the 7-year study period, 229,384 EMS missions were completed. From 2015 to 2021, the total number of EMS missions increased by 8.5%. A tele-EMS physician was consulted on 23,172 (10.1%) missions. The proportion of telemedicine missions increased from 8.6% in 2015 to 12.9% in 2021. Teleconsultations for missions with tracer diagnoses decreased during from 43.7% to 30.7%, and the proportion of non-tracer diagnoses increased from 56.3% to 69.3%. The call duration for teleconsultation decreased from 12.07 min in 2015 to 9.42 min in 2021. For every fourth mission, one or more simultaneous teleconsultations were conducted by the tele-EMS physician on duty. The implementation and routine use of a tele-EMS system increased the availability of onsite EMS physicians and enabled immediate onsite support for paramedics. Parallel teleconsultations, reduction in call duration, and increase in ambulatory onsite treatments over the years demonstrate the increasing experience of paramedics and tele-EMS physicians with the system in place. A prehospital tele-EMS system is important for mitigating the current challenges in the prehospital emergency care sector.

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.

[Is a tele-emergency physician system a sensible addition in rural German regions?-An analysis from a medical and economic perspective]

Hintergrund und Ziel

Um die präklinische Notfallversorgung zu optimieren und aktuelle Herausforderungen zu bewältigen, wurde im Landkreis Vorpommern-Greifswald im Jahr 2017 ein Telenotarzt-System eingeführt. Es sollte aus medizinischer und ökonomischer Sicht geprüft werden, ob dies, insbesondere im ländlichen Raum, eine effiziente Ergänzung der präklinischen Notfallversorgung darstellt.

Methodik

Es wurden ca. 250.000 Einsatzdaten, vor und nach Einführung des Systems, über die Jahre 2015 bis 2020 ausgewertet und ein Prä-Post-Vergleich über die Einsatzstruktur erstellt. Die 3611 Einsätze der Telenotärztinnen und -ärzte (TNA) wurden nach medizinischen Indikationen und zeitlichen Faktoren analysiert sowie mit Einsätzen ohne TNA verglichen. Zusätzlich erfolgten eine Analyse der Gesamtkosten des neuen Versorgungskonzeptes sowie eine Kostenanalyse der prä- und innerklinischen Behandlungskosten ausgewählter Erkrankungen.

Ergebnisse

Das Einsatzspektrum des TNA umfasste alle Altersstufen mit verschiedenen Meldebildern, die zu 48,2 % eine mittlere Erkrankungsschwere (stationäre Behandlung erforderlich) hatten. Von Patient*innen und Mitarbeitenden wurde das System gut angenommen. Die Einsatzdaten zeigten einen signifikanten Rückgang der Notarztbeteiligung bei telenotarztfähigen Einsatzfahrzeugen um 20 %. Die jährlichen Kosten des Systems belaufen sich auf ca. 1,7 Mio. €.

Schlussfolgerung

Die Ergebnisse belegen die Vorteilhaftigkeit des TNA-Systems, sodass es über die Projektdauer hinaus implementiert wurde. Das System ist medizinisch sinnvoll, funktionsfähig sowie effizient und steht als Innovation für die Umsetzung in ganz Deutschland bereit.

Epidemiological Analysis of Patients with Pre-Hospital First Aid in Keyouqian Banner, Hinggan League, Inner Mongolia

Objective

To summarize the characteristics of patients calling the 120 emergency number for pre-hospital first aid in Keyouqian Banner, Hinggan League.

Methods

The clinical data of adult patients with pre-hospital first aid from 2016 to 2018 were retrospectively analyzed.

Results

There were 2711 cases with pre-hospital first aid. Males significantly outnumbered females. Young and middle-aged patients comprised 81.5%. Patients were mainly Han and Mongolians. Most injuries and illnesses occurred at home and on the road. The time to arrival of medical services was 30.34 ± 28.29 minutes. The proportion of pre-hospital first aid for trauma was the highest, followed by diseases concerning the cardiovascular and neurological systems. The proportion of patients with improved medical conditions after onsite first aid was 43.3%, the proportion with unchanged conditions was 51.7%, and the total mortality rate was 3.9%.

Conclusion

The disease spectrum, ethnic distribution, age at onset, and pre-hospital first aid capabilities for outpatients were analyzed. These results may facilitate the establishment of a pre-hospital first aid system for the local prevention and control of acute and critical illnesses, increase the success rate of the region's pre-hospital first aid services, and improve the prognosis.

Telenotarztsysteme im deutschen Rettungsdienst: eine nationale Sachstandserhebung

Hintergrund und Fragestellung

Bislang liegen nur wenige Daten über den aktuellen Ausbaustand von Telenotarzt(TNA)-Systemen im deutschen Rettungsdienst vor. In einer nationalen Befragung wurde der Sachstand zu Ausbau und Nutzung von TNA-Systemen erhoben.

Material und Methode

Durchführung einer Online-Befragung unter aktiv im deutschen Rettungsdienst tätigen Personen zum Vorhandensein eines TNA-Systems und dessen Ausgestaltung, zu Standardarbeitsanweisungen (SAA) für Rettungsfachpersonal in ausgewählten Einsatzszenarien sowie zu persönlichen Einschätzungen zum Themenkomplex TNA.

Ergebnisse

1023 Teilnehmer aus 77,1 % (n = 299) aller deutschen Rettungsdienstbereiche nahmen teil. 90,3 % (n = 270) der Bereiche hatten kein TNA-System, ein mindestens teilweiser Betrieb war in 9,3 % (n = 29) etabliert. Die Ausgestaltung ist heterogen, die SAA für Rettungsfachpersonal unterscheiden sich auch innerhalb einzelner Bundesländer und zwischen Bereichen mit und ohne TNA erheblich. Regionen mit TNA verfügen zu einem größeren Anteil über SAA und führen einzelne Maßnahmen häufiger durch. So ist eine intravenöse Analgesie durch den Rettungswagen (RTW) bei 0,8 % vs. 8,9 % (n = 1 vs. n = 76) der Teilnehmenden nicht vorgesehen, die Gabe von Acetylsalicylsäure bei akutem Koronarsyndrom ohne ST-Hebung erfolgt in 3,1 % vs. 23,1 % (n = 4 vs. n = 198) nicht. Bei der persönlichen Einschätzung zum Thema TNA besteht ein signifikanter Unterschied zwischen Bereichen mit und ohne vorhandenes TNA-System.

Schlussfolgerungen

Im deutschen Rettungsdienst sind in weniger als einem Zehntel der Bereiche TNA-Systeme in Betrieb und die vorhandenen Systeme sind sehr heterogen gestaltet. Gleiches gilt für das Vorhandensein von Standardarbeitsanweisungen. Dies legt nahe, dass bei nationaler Betrachtung relevante Unterschiede in der notfallmedizinischen Versorgungsqualität der Bevölkerung bestehen.

Digitale Systeme zur Unterstützung von präklinischen Notfalleinsätzen

Hintergrund und Fragestellung

Steigende Anforderungen an Dokumentation und sektorenübergreifende Kommunikation führen zu vermehrtem organisatorischem Aufwand im Notarzt- und Rettungsdienst. Die Verwendung digitaler Informationssysteme im präklinischen Einsatz kann sowohl dazu beitragen, Einsatzkräfte bei diesen Aufgaben zu unterstützen als auch neue Behandlungsmöglichkeiten für Patienten eröffnen. Die Arbeit versucht, ein möglichst umfassendes Bild der derzeitigen Verbreitung und Nutzung von Informations- und Kommunikationssystemen zur Einsatzunterstützung in Deutschland zu erstellen.

Material und Methoden

Die Querschnittsstudie wurde als deutschlandweite, explorative Online-Befragung unter Notärzten und Rettungsdienstfachpersonal von Juli bis August 2020 durchgeführt. Die anschließende Datenanalyse erfolgte durch deskriptive Statistikmethoden. Betrachtet wurden u. a. Lösungen für die digitale Dokumentation und Krankenhausvoranmeldung, für den Versorgungsnachweis und Telenotarztdienst sowie der Digitalfunk.

Ergebnisse

Es wurden 821 Antwortbogen von 481 Rettungswachen aus insgesamt 382 Städten in der Auswertung berücksichtigt. Die Verfügbarkeit von 16 untersuchten Systemen variiert deutschlandweit je nach Bundesland und Anwendungsbereich. Befragte Einsatzkräfte zeigen sich gegenüber neuen Technologien und Möglichkeiten grundsätzlich offen, wenngleich die aktuelle Umsetzung als nicht zufriedenstellend bewertet wird. Herausforderungen zeigen sich v. a. hinsichtlich Verlässlichkeit, Hardware, Benutzerfreundlichkeit und Interoperabilität.

Diskussion

Eine weitreichende Digitalisierung der präklinischen Notfallmedizin wurde in Deutschland bislang nicht erreicht. Die ganzheitliche Betrachtung und vernetzte Implementierung aller am Einsatz beteiligten Systeme und Prozesse kann dazu beitragen, digitale Lösungen für die Präklinik zu verbessern und weiter zu verbreiten.

Drones Delivering Automated External Defibrillators-Integrating Unmanned Aerial Systems into the Chain of Survival: A Simulation Study in Rural Germany

BACKGROUND

Community first responders (CFR) improve survival in out-of-hospital cardiac arrest (OHCA) but are often hampered by limited availability of public access defibrillation. Unmanned aerial systems (UAS) delivering automated external defibrillators (AED) directly to an OHCA site could help overcome this. We evaluated the feasibility of integrating UAS into the chain of survival in rural Northeast Germany.

METHODS

This simulation study explored UAS-AED delivery combined with a smartphone-based CFR dispatch. Five OHCA locations (A-E) were randomly selected. We routed a flight corridor to each of these sites from a corresponding UAS base; 50 OHCA scenarios with 10 flights per corridor were scheduled. All steps were accurately simulated, from a bystander finding the patient, making an emergency call, conducting dispatcher-assisted cardiopulmonary resuscitation, and simultaneous CFR plus UAS deployment, to the bystander and CFR interacting with UAS and AED. This process was time-tracked and video-recorded until defibrillation.

RESULTS

We performed 46 OHCA simulations. Missions were flown autonomously but needed pilot assistance during landing. Distances (km) and average time intervals from alert to defibrillation (t_d in min:sec±SD) were 0.4 (6:02±0:56), 2.29 (6:53±0:19), 4.0 (8:54±0:25), 7.43 (14:51±1:055), and 9.79 (15:51±1:16) for routes A to E, respectively. All participants were able to retrieve the AED within seconds after UAS landing and interacted safely with the UAS and AED.

CONCLUSIONS

Integrating airborne AED delivery into the chain of survival appeared feasible and safe but remains an experimental technology. Linking this with CFR potentially improves the availability of early public-access defibrillation, particularly in rural regions.

The Recent Progress and Applications of Digital Technologies in Healthcare: A Review

BACKGROUND

The implementation of medical digital technologies can provide better accessibility and flexibility of healthcare for the public. It encompasses the availability of open information on the health, treatment, complications, and recent progress on biomedical research. At present, even in low-income countries, diagnostic and medical services are becoming more accessible and available. However, many issues related to digital health technologies remain unmet, including the reliability, safety, testing, and ethical aspects.

PURPOSE

The aim of the review is to discuss and analyze the recent progress on the application of big data, artificial intelligence, telemedicine, block-chain platforms, smart devices in healthcare, and medical education. Basic Design. The publication search was carried out using Google Scholar, PubMed, Web of Sciences, Medline, Wiley Online Library, and CrossRef databases. The review highlights the applications of artificial intelligence, "big data," telemedicine and block-chain technologies, and smart devices (internet of things) for solving the real problems in healthcare and medical education. Major Findings. We identified 252 papers related to the digital health area. However, the number of papers discussed in the review was limited to 152 due to the exclusion criteria. The literature search demonstrated that digital health technologies became highly sought due to recent pandemics, including COVID-19. The disastrous dissemination of COVID-19 through all continents triggered the need for fast and effective solutions to localize, manage, and treat the viral infection. In this regard, the use of telemedicine and other e-health technologies might help to lessen the pressure on healthcare systems. Summary. Digital platforms can help optimize diagnosis, consulting, and treatment of patients. However, due to the lack of official regulations and recommendations, the stakeholders, including private and governmental organizations, are facing the problem with adequate validation and approbation of novel digital health technologies. In this regard, proper scientific research is required before a digital product is deployed for the healthcare sector.
