Comparison of Palliative Knowledge and Self-Efficacy Expectation of German Paramedics Between a Rural and an Urban Structured Emergency Medical Service Area

OBJECTIVE(S)

Differences in the German emergency medical service (EMS) can be seen in the countryside in contrast to the city with regard to travel distances to hospitals and in the access routes of EMS-physicians. In order to investigate the success of establishment of palliative crisis cards associated with training and the rural and urban EMS structures, two urban and two rural EMS areas were compared using the Paramedic Palliative Care Test (PARPACT). Methods: The PARPACT includes test items on palliative knowledge (PK, maximum score: 15 points) and palliative self-efficacy expectations (PSE, maximum score: 18 points), as well as items on palliative attitudes in dealing with palliative care patients. We used a 4-point Likert-type scale. For data analysis, nonparametric tests (χ-test and Mann-Whitney U test) were used in addition to descriptive analysis (frequencies, means, medians, standard deviations, and ranges). Results: In total, 291 out of 750 ambulance or EMS personnel participated in the voluntary survey. Rural ambulance or EMS personnel answered the PK-questions correctly more often on average (mean: 11.19, SD: 1.85) than urban ambulance or EMS personnel (mean: 9.18, SD: 2.39; Mann-Whitney U test: U=5040.000, P=.001). In addition, ambulance or EMS personnel with the highest level of training (3-year-trained paramedics) performed better in PK (mean: 10.38, SD: 2.31) than less intensively training ambulance or EMS personnel (mean: 9.58, SD: 2.43; Mann-Whitney U-test: U=8446.500, P=.004). In terms of PSE, rural ambulance or EMS personnel also achieved higher mean PSE-scores (mean: 12.55, SD: 2.60) than urban ambulance or EMS personnel (mean: 9.77, SD: 3.41; Mann-Whitney U-test: U=5148.500, P=.001). Conclusions: Better training in the EMS is associated with improved PK compared to less qualified nonphysician EMS staff. The establishment of palliative crisis cards and the structures in the city alone do not lead to improved knowledge and PSE.

[Update tele-emergency medicine : Status quo and perspectives]

CURRENT STATUS OF EMERGENCY MEDICINE IN GERMANY

Increasing numbers of rescue missions in recent years have led to a growing staff shortage of paramedics as well as physicians in the emergency medical system (EMS) with an urgent need for optimized usage of resources. One option is the implementation of a tele-EMS physician system, which has been established in the EMS of the City of Aachen since 2014.

IMPLEMENTATION OF TELE-EMERGENCY MEDICINE

In addition to pilot projects, political decisions lead to the introduction of tele-emergency medicine. The expansion is currently progressing in various federal states, and a comprehensive introduction has been decided for North Rhine-Westphalia and Bavaria. The adaptation of the EMS physician catalog of indications is essential for the integration of a tele-EMS physician.

STATUS QUO OF TELE-EMERGENCY MEDICINE

The tele-EMS physician offers the possibility of a long-term and comprehensive EMS physician expertise in the EMS regardless of location and, therefore, to partially compensate for a lack of EMS physicians. Tele-EMS physicians can also support the dispatch center in an advisory capacity and, for example, clarify secondary transport. A uniform qualification curriculum for tele-EMS physicians was introduced by the North Rhine and Westphalia-Lippe Medical Associations.

OUTLOOK

In addition to consultations from emergency missions, tele-emergency medicine can also be used for innovative educational applications, for example, in the supervision of young physicians or recertification of EMS staff. A lack of ambulances could be compensated for by a community emergency paramedic, who could also be connected to the tele-EMS physician.

[PARPACT: Paramedic Palliative Care Test : Validation of a questionnaire to assess palliative care knowledge and self-efficacy expectations of paramedics]

BACKGROUND

Given the large number of palliative patients cared for by the emergency services, education and training in palliative care topics are playing an increasingly important role. To support decision-making in an emergency setting a palliative or emergency card has been introduced in many cities.

OBJECTIVES

To assess the success of educational interventions and the effect of the palliative or emergency card, a questionnaire was developed and validated to determine palliative knowledge and palliative self-efficacy expectations in the emergency services.

MATERIALS AND METHODS

A Delphi process was applied for development and content validation. Factor analysis was used for construct validation. Criterion validity was assessed with the help of 22 nurses specially trained in palliative care. Reliability was determined using Cronbach's alpha as a measure of internal consistency.

RESULTS

In all, 291 of 750 paramedics participated in the voluntary survey. After completion of the Delphi process, there was consensus that the important topics of pain, dyspnea, sedation, end-of-life care, euthanasia, and legal aspects were covered in the questionnaire. Factor analysis was in favor of a six-factor solution. Criterion validation revealed a significant difference in palliative knowledge between palliative care nurses (MRang 289.73) and paramedics (MRang 146.97, U = 281.000, r = 0.40, p < 0.001). Cronbach's alpha was 0.70 for the knowledge questions and 0.82 for the palliative care self-efficacy expectancy subscale.

CONCLUSIONS

The Paramedic Palliative Care Test (PARPACT) is a validated measurement tool for testing educational interventions in paramedicine.

[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.

„Entrustable professional activities“ für NotfallsanitäterInnen

Hintergrund

Wie in vielen medizinischen Berufen wird auch bei den NotfallsanitäterInnen (NotSan) der Kompetenzbegriff verwendet. Eine Möglichkeit, diese Kompetenz schrittweise entwickeln und messen zu können, steht aus. Ten Cate et al. schlagen hier das Konzept der „entrustable professional activities“ (EPA) vor. Ziel der Studie war, einen Katalog von relevanten Einsatzsituationen zu entwickeln, der die Grundlage für eine EPA-Integration in die Ausbildung ermöglicht.

Methode

Die Erarbeitung des EPA-Katalogs erfolgte über ein 2‑stufiges Verfahren mittels webbasierter Fragebögen. Nach einer eDelphi-Analyse mit Praxisanleitenden im Rettungsdienst, wurden die Items in einem großen Kollektiv hinsichtlich der Relevanz validiert. Anschließend wurden Faktoren identifiziert und Skalen gebildet.

Ergebnisse

Nach Validierung der Ergebnisse der eDelphi-Analyse ergaben sich fünf Skalen mit 22 Items. Sie umfassen die Bereiche „Behandlung spezieller Krankheitsbilder-NACA IV“, „Kommunikation“, „Einbinden von Medizinprodukten in die Patientenbehandlung“, „symptomorientiertes Handeln“ und „Leitsymptom Schmerz“. Die Items beschreiben 59 % der Gesamtvarianz und entsprechen einer stabilen Faktorenlösung.

Schlussfolgerung

Es konnte ein Katalog von relevanten Einsatzsituationen in der NotSan-Ausbildung entwickelt werden, der sich zur weiteren Entwicklung von EPA eignet. Diese sollten flächendeckend und organisationsübergreifend einheitlich genutzt werden. Die Nutzung sollte didaktisch wissenschaftlich begleitet werden.

Structured evaluation of stress triggers in prehospital emergency medical care : An analysis by questionnaire regarding the professional groups

BACKGROUND

Emergency medical services work in the environment of high responsibility teams and have to act under unpredictable working conditions. Stress occurs and has potential of negative effects on tasks, teamwork, prioritization processes and cognitive control. Stress is not exclusively dictated by the situation-the individuals rate the situation of having the necessary skills that a particular situation demands. There are different occupational groups in the emergency medical services in Germany. Training, tasks and legal framework of these groups vary.

OBJECTIVE

The aim of this study was to identify professional group-specific stressors for emergency medical services. These stress situations can be used to design skills building tools to enable individuals to cope with these stressors.

MATERIAL AND METHODS

The participants were invited to the study via posters and social media. An expert group (minimum 6 months of experience) developed a set of items via a two-step online Delphi survey. The experts were recruited from all professional groups represented in the German emergency medical service. We evaluated the resulting parameters for relevance and validity in a larger collective. Lastly, we identified stress factors that could be grouped in relevant scales. In total 1017 participants (paramedics, physicians) took part in the final validation survey.

RESULTS

After validation, we identified a catalogue of stressors with 7 scales and 25 items for EMT (Emergency Medical Technician) paramedics (KMO [Kayser-Meyer-Olkin criterion] 0.81), 6 scales and 24 items for advanced paramedics (KMO 0.82) and 6 scales and 24 items for EMS (Emergency Medical Service) physicians (KMO 0.82). For the professional group of EMT basic, the quality parameters did not allow further processing of the items. Professional group-specific scales for EMT paramedics are "professional limitations", "organizational framework", "expectations" and "questions of meaning". For advanced paramedics "appreciation", "exceptional circumstances" and "legal certainty" were identified. The EMT physicians named "handling third parties", "tolerance to ambiguity", "task management" and "pressure to act". A scale that is representative for all professional groups is "teamwork". Organizational circumstances occur in all groups. The item "unnecessary missions" for EMT paramedics and "legal concerns with the application of methods" for advanced paramedics are examples.

DISCUSSION

Different stressors are relevant for the individual professional groups in the German emergency medical service. The developed catalogue can be used in the future to evaluate the subjective stress load of emergency service professionals. There are stressors that are inherent in the working environment (e.g. pressure to act) and others that can be improved through training (teamwork). We recommend training of general resistance as well as training of specific items (e.g., technical, nontechnical skills). All professionals mentioned items with respect to organizational factors. The responsible persons can identify potential for improvement based on the legal and organizational items. The EMT basic requires further subdivision according to task areas due to its variable applicability.

[Appropriate allocation of resources for interhospital transfer in emergency medical service-is a physician in the dispatch center helpful?]

BACKGROUND

The number of interhospital transfers is constantly increasing because of specialization of medical facilities, capacity balancing between intensive care units as well as earlier rehabilitation procedures. This leads to an increase in requests for emergency physicians to accompany patient transfers. This study investigated whether clarification of interhospital transport by an emergency physician at the dispatch center can optimize the use of emergency services resources.

METHOD

All transport clarifications performed by a tele-emergency physician between 1 January 2018 and 31 December 2019 were retrospectively analyzed as well as the transport request forms. Furthermore, all data on the number and alarmed rescue resources for interhospital transfers in the city of Aachen from 2013 onwards were exported from the dispatch center databank and included in the evaluation.

RESULTS

In total 2333 requests for interhospital patient transfers from 2018 and 2019 were analyzed as well as 10,923 transports recorded from 2013 to 2019. The number of patient transfers accompanied by an emergency physician from 2013 to 2019 was significantly reduced from 786 (68.2%) to 495 (30.5%, p > 0.001). The correct resources of rescue vehicles and staff was requested in 1816 cases (77.8%). The urgency of emergency patient transfers was correctly evaluated in 567 (89.2%) cases. In total 526 assignments were carried out without an emergency physician and 315 of these patients were accompanied by a tele-emergency physician during transfer.

CONCLUSION

The immediate clarification of interhospital transport requests by an emergency physician at the dispatch center leads to a significant reduction in unnecessary medical accompaniment of patient transfers. The choice of an appropriate transfer vehicle and staff should not be left to the requesting hospital physician alone.

[Analgesia in the emergency medical service: comparison between tele-emergency physician and call back procedure with respect to application safety, effectiveness and tolerance]

BACKGROUND

Acute pain is a common reason for calling emergency medical services (EMS) and can require medication depending on the pain intensity. German EMS personnel feel strong pressure to reduce a patient's pain but are restricted by law. Currently, German federal law only allows the administration of opioid-containing drugs by or on the order of a physician, while in other European countries (e.g. Switzerland and The Netherlands) the administration of opioid-based analgesia by trained and certified paramedics is common practice. Consequently, a patient in Germany experiencing acute pain needs the attendance of an emergency physician in EMS missions. According to international standards pain reduction on the numeric rating scale (NRS) score by ≥2 or a NRS score ≤4 at the end of the patient transport is considered to be adequate.

OBJECTIVE

Comparison of two different algorithm-based concepts for analgesia with consultation of a physician analyzing the efficacy, tolerance and safety of application.

MATERIAL AND METHODS

In a retrospective cohort study in two different regions, two physician-supported algorithm-based analgesia concepts, a call back-supported concept (EMS Schleswig-Holstein: RKiSH) and a tele-EMS physician-based concept (EMS Aachen: RDAC), were compared over 2 years. The call back-supported concept is based on specific algorithms and certification of EMS personnel. In Aachen, the tele-EMS physician is integrated into the routine EMS system and includes immediate vital data transmission.

RESULTS

Over a period of 2 years call back-supported analgesia was administered in 878 cases (2016: 428, 2017: 450) and telemedically assisted analgesia was used in 728 cases (2015: 226, 2016: 502). Call back vs. telemedicine: initial NRS scores were 9 (8-10) and 8 (6-9), respectively (p < 0.0001); NRS scores were reduced by 4 (3-5) and 5 (3-6), respectively (p = 0.0002), leading to mean NRS scores of 4 (3-6) vs. 3 (2-4), respectively (p < 0.0001) at patient handover/emergency room arrival. Clinically relevant pain reduction was achieved in both groups. Complete NRS documentation was conducted in 753 (85.8%) vs. 673 (92.4%) cases, respectively, p = 0. Severe adverse events did not occur in either of the groups.

CONCLUSION

The administration of analgesia by EMS personnel with teleconsultation of a physician is effective and has a low rate of complications, particularly morphine. Overall, algorithm-based call back-supported as well as telemedically supported analgesia concepts based on regular training improve the management of pain in the prehospital setting. In addition, the resources of the emergency physician remain available for life-threatening emergencies. The training, certification and supervision of EMS personnel is very important in both systems to ensure the best pain management care and patient safety. Adjustments to the federal law on the administration of analgesics would facilitate the realization of algorithm-based concepts by paramedics as pain reduction could be performed with delegation by a medical director without consulting another physician.
