Medical experience as an influencing parameter in emergency medical care for psychiatric emergencies: retrospective analysis of a multicenter survey

BACKGROUND

Prehospital care of psychiatric patients often relies on the medical experience of prehospital emergency physicians (PHEPs). The psychiatrists (PSs) involved in the further treatment of psychiatric patients also often rely on their experience. Furthermore, the interaction between PHEPs and PSs is characterized by interaction problems and different approaches in the prehospital care of the psychiatric emergency.

OBJECTIVES

To analyze the phenomenon of "medical experience" as a cause of possible interaction-related problems and assess its impact on the prehospital decision-making process between prehospital emergency physicians and psychiatrists.

METHODS

The retrospective data analysis was conducted between November 2022 and March 2023. Medical experience was defined as follows, based on the demographic information collected in the questionnaires: For PHEPs, the period since obtaining the additional qualification in emergency medicine was defined as a surrogate marker of medical experience: (i) inexperienced: < 1 year, (ii) experienced: 1-5 years, (iii) very experienced: > 5 years. For PSs, age in years was used as a surrogate parameter of medical experience: (i) inexperienced: 25-35 years, (ii) experienced: 35-45 years, (iii) very experienced: > 45 years.

RESULTS

Inexperienced PSs most frequently expressed anxiety about the psychiatric emergency referred by a PHEP (27.9%). Experienced PHEPs most frequently reported a lack of qualifications in handling the care of psychiatric emergencies (p = 0.002). Very experienced PHEPs were significantly more likely to have a referral refused by the acute psychiatric hospital if an inexperienced PS was on duty (p = 0.01). Experienced PHEPs apply an intravenous hypnotic significantly more often (almost 15%) than PSs of all experience levels (p = 0.001). In addition, very experienced PHEPs sought prehospital phone contact with acute psychiatry significantly more often (p = 0.01).

CONCLUSION

PHEPs should be aware that the PS on duty may be inexperienced and that treating emergency patients may cause him/her anxiety. On the other hand, PHEPs should be receptive to feedback from PS who have identified a qualification deficiency in them. Jointly developed, individualized emergency plans could lead to better prehospital care for psychiatric emergency patients. Further training in the prehospital management of psychiatric disorders is needed to minimize the existing skills gap among PHEPs in the management of psychiatric disorders.

Pre-hospital endotracheal intubation in severe traumatic brain injury: ventilation targets and mortality-a retrospective analysis of 308 patients

BACKGROUND

Traumatic brain injury (TBI) remains one of the main causes of mortality and long-term disability worldwide. Maintaining physiology of brain tissue to the greatest extent possible through optimal management of blood pressure, airway, ventilation, and oxygenation, improves patient outcome. We studied the quality of prehospital care in severe TBI patients by analyzing adherence to recommended target ranges for ventilation and blood pressure, prehospital time expenditure, and their effect on mortality, as well as quality of prehospital ventilation assessed by arterial partial pressure of CO2 (PaCO2) at hospital admission.

METHODS

This is a retrospective cohort study of all TBI patients requiring tracheal intubation on scene who were transported to one of two major level 1 trauma centers in Switzerland between January 2014 and December 2019 by Swiss Air Rescue (Rega). We assessed systolic blood pressure (SBP), end-tidal partial pressure of CO2 (PetCO2), and PaCO2 at hospital admission as well as prehospital and on-scene time. Quality markers of prehospital care (PetCO2, SBP, prehospital times) and prehospital ventilation (PaCO2) are presented as descriptive analysis. Effect on mortality was calculated by multivariable regression analysis and a logistic general additive model.

RESULTS

Of 557 patients after exclusions, 308 were analyzed. Adherence to blood pressure recommendations was 89%. According to PetCO2, 45% were normoventilated, and 29% had a SBP ≥ 90 mm Hg and were normoventilated. Due to the poor correlation between PaCO2 and PetCO2, only 33% were normocapnic at hospital admission. Normocapnia at hospital admission was strongly associated with reduced probability of mortality. Prehospital and on-scene times had no impact on mortality.

CONCLUSIONS

PaCO2 at hospital admission is strongly associated with mortality risk, but normocapnia is achieved only in a minority of patients. Therefore, the time required for placement of an arterial cannula and prehospital blood gas analysis may be warranted in severe TBI patients requiring on-scene tracheal intubation.

[Quality of documentation and treatment in the non-physician staffed ambulance: a retrospective analysis of emergency protocols from the city of Aachen]

Hintergrund

Der deutsche Rettungsdienst wird jährlich zu ca. 7,3 Mio. Einsätzen alarmiert, welche zu einem Großteil (ca. 59 %) ohne Arzt ablaufen. Da kaum Daten zur Qualität der medizinischen Versorgung und Dokumentation von Rettungsdiensteinsätzen ohne Arzt vorliegen, sollen diese anhand der Einsatzprotokolle im Rahmen dieser Studie überprüft werden.

Methode

Es erfolgte eine retrospektive Analyse von Protokollen der Rettungsdiensteinsätze ohne Arzt aus den Monaten Juni und Juli 2018. Unter Einbezug von Verfahrensanweisungen wurden die Dokumentations- und Behandlungsqualität der Einsätze analysiert. Primäre Endpunkte waren Dokumentationshäufigkeit, Vollständigkeit, die korrekte Notarzt- oder Telenotarztindikationsstellung, die Entwicklung von kritischen Vitalparametern im Einsatzverlauf sowie die mediane Behandlungszeit.

Ergebnisse

Insgesamt wurden 1935 Protokolle ausgewertet. Die Verdachtsdiagnose wurde in 1323 (68,4 %), die Anamnese in 456 (23,6 %), der Erstbefund in 350 (18,1 %) und der Letztbefund in 52 (2,7 %) der Fälle vollständig dokumentiert. Anhand der Dokumentation bestand bei 531 (27 %) Patienten eine Telenotarzt- bzw. Notarztindikation, jedoch kein Arztkontakt. Bei diesen Patienten wurden 410 kritische Vitalparameter im Erstbefund dokumentiert. Von diesen Vitalwerten verbesserten sich 69 (16,8 %); bei 217 (52,9 %) wurde kein Übergabebefund dokumentiert. Die mediane Behandlungsdauer vor Ort war bei Patienten mit eigentlicher Notarztindikation (15:02 min) signifikant länger als bei Patienten ohne Indikation (13:05 min).

Schlussfolgerung

Die Dokumentation der Einsätze ist defizitär. Zudem könnte ein Viertel der Patienten von einem prähospitalen Arztkontakt profitieren. Eine juristisch bedenkliche Übergabedokumentation besteht bei ca. der Hälfte aller Protokolle.

[Emergency medical service, medical on-call service, or emergency department : Germans unsure whom to contact in acute medical events]

BACKGROUND

In medical events, patients have to independently decide whom to contact: emergency medical services, medical on-call service or emergency department.

OBJECTIVES

Are Germans able to assess the urgency of medical events and choose the correct resource?

MATERIALS AND METHODS

In 2018 a nationwide anonymous telephone survey was done in Gabler-Haeder design. In all, 708 interviewees were presented with six medical scenarios. Participants were asked to rate urgency and to assess whether medical help was necessary within minutes to hours. Telephone numbers of emergency medical services and medical on-call service were inquired.

RESULTS

Urgency of different scenarios was often misjudged: in cases with high, medium, and low urgency the misjudgement rate were 20, 50, and 27%, respectively. If medical help was rated as necessary, some participants chose the wrong service: 25% would not call an ambulance in stroke or myocardial infarction. In cases with medium urgency, more respondents chose to consult an emergency department (38%) than to call medical on-call service (46%).

CONCLUSIONS

Knowledge regarding different options for treatment of medical events and competence to assess urgency seem to be too low. Beside efforts to increase health literacy, one solution might be to introduce a joint telephone number for emergency medical services and medical on-call service with a uniform assessment tool and appropriate allocation.

Analysis of tracheal intubation in out-of-hospital helicopter emergency medicine recorded by video laryngoscopy

Background

Tracheal intubation remains the gold standard of airway management in emergency medicine and maximizing safety, intubation success, and especially first-pass intubation success (FPS) in these situations is imperative.

Methods

We conducted a prospective observational study on all 12 helicopter emergency medical service (HEMS) bases of the Swiss Air Rescue, between February 15, 2018, and February 14, 2019. All 428 patients on whom out-of-hospital advanced airway management was performed by the HEMS crew were included. The C-MAC video laryngoscope was used as the primary device for tracheal intubation. Intubation procedures were recorded by the video laryngoscope and precise time points were recorded to verify the time necessary for each attempt and the overall procedure time until successful intubation. The videos were further analysed for problems and complications during airway management by an independent reviewer. Additionally, a questionnaire about the intubation procedure, basic characteristics of the patient, circumstances, environmental factors, and the provider’s level of experience in airway management was filled out. Main outcome measures were FPS of tracheal intubation, overall success rate, overall intubation time, problems and complications of video laryngoscopy.

Results

FPS rate was 87.6% and overall success rate 98.6%. Success rates, overall time to intubation, and subjective difficulty were not associated to the providers’ expertise in airway management. In patients undergoing CPR FPS was 84.8%, in trauma patients 86.4% and in non-trauma patients 93.3%. FPS in patients with difficult airway characteristics, facial trauma/burns or obesity ranges between 87 and 89%. Performing airway management indoors or inside an ambulance resulted in a significantly higher FPS of 91.1% compared to outdoor locations (p < 0.001). Direct solar irradiation on the screen, fogging of the lens, and blood on the camera significantly impaired FPS. Several issues for further improvements in the use of video laryngoscopy in the out-of-hospital setting and for quality control in airway management were identified.

Conclusion

Airway management using the C-MAC video laryngoscope with Macintosh blade in a group of operators with mixed experience showed high FPS and overall rates of intubation success. Video recording emergency intubations may improve education and quality control.

[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.

[Analysis of a first responder system for emergency medical care in rural areas: first results and experiences]

BACKGROUND

In emergency situations it is essential to get access to medical treatment as early as possible. In Germany, the time interval from alarm to arrival should be less than 10-15 min. The emergency medical service (EMS) cannot comply with this recommendation in approximately 10% of the emergencies in Baden-Württemberg. In addition to the traditional EMS system, a voluntary system of first responders has been developed over the last years to reduce this interval. They are incorporated into the alarm system of the traditional EMS and are alarmed as soon as an emergency call arrives. Data on process times (from alarm to begin of treatment or duration of treatment until arrival of EMS) and quality are rare. In Baden-Württemberg, the emergency aid "Deutsche Lebens-Rettungs-Gesellschaft e.V. (DLRG)" Nordhardt can only estimate times and quality of primary care. The objective of this analysis was to describe and evaluate such a first responder system.

METHODS

The presented study investigated the emergency responses of a first responder system in Nordhardt, close to Karlsruhe, Germany. A total of 367 emergency data sets from 2017 containing information on operating time, medical history, suspected diagnosis and medical treatment, were evaluated. Of these, 363 anonymized emergency records including the complete information (concerning process time and medical treatment) were analyzed. The focus was on different time intervals from alarm to treatment and until arrival of the EMS. Additionally, the quality of medical treatment and the measured vital data were examined.

RESULTS

The median response time and time to access to the patient was 2 min in both. The patient was reached within approximately 4 min and treated for another 5 min until the EMS arrived. In two thirds of the patients, the vital parameters were measured, 5 patients were resuscitated, 23 received supplementary oxygen, 4 patients were ventilated and 11 patients suffering from hypoglycemia showed a clinical benefit from the early treatment. A total of 50 trauma patients were treated, 5 with cervical spine stabilization and 38 received a body check.

CONCLUSION

The first responders from Nordhardt received an emergency call nearly every day. In two thirds of the calls they were faster than the EMS as they usually have local sites with a shorter distance to the emergency scene where they are able to deal with critical medical cases until the EMS arrives. Despite the small case numbers, it could be concluded that the early medical treatment with respect to resuscitation based on earlier arrival on site may help to increase the survival rate of patients. The first responders were also able to manage airway problems with additional oxygen or other airway devices. Other medical treatment performed by the first responders, such as administration of glucose in hypoglycemic patients positively affected the patient's condition. There is a tactical advantage to include first responders in traditional EMS services. Further studies are needed to examine these questions in larger samples also over a longer time period. Standardization and digitalization of the records could help to gain more data in this field.

Differences in pain treatment between surgeons and anaesthesiologists in a physician staffed prehospital emergency medical service: a retrospective cohort analysis

Background

Although pain treatment is an important objective in prehospital emergency medicine the incidence of oligoanalgesia is still high in prehospital patients. Given that prehospital emergency medicine in Germany is open for physicians of any speciality, the prehospital pain treatment may differ depending on the primary medical education. Aim of this study was to explore the difference in pain treatment between surgeons and anaesthesiologists in a physician staffed emergency medical service.

Methods

Retrospective single centre cohort analysis in a physician staffed ground based emergency medical service from January 2014 until December 2016. A total of 8882 consecutive emergency missions were screened. Primary outcome measure was the difference in application frequency of prehospital analgesics by anaesthesiologist or surgeon. Univariate and multivariate logistic regression analysis was used for statistical analysis including subgroup analysis for trauma and acute coronary syndrome.

Results

A total of 8238 patients were included in the analysis. There was a significant difference in the application frequency of analgesics between surgeons and anaesthesiologists especially for opioids (p < 0.001, OR 0.68 [0.56–0.82]). Fentanyl was the most common administered analgesic in the trauma subgroup, but significantly less common used by surgeons (p = 0.005, OR 0.63 [0.46–0.87]). In acute coronary syndrome cases there was no significant difference in morphine administration between anaesthesiologists and surgeons (p = 0.49, OR 0.88 [0.61–1.27]).

Conclusions

Increased training for prehospital pain treatment should be implemented, since opioids were administered notably less frequent by surgeons than by anaesthesiologists.

[Future of emergency medicine in Germany 2.0]

In 2003 an article on the future of prehospital emergency medicine in Germany was published in the journal Der Anaesthesist. Emergency medicine in Germany, which at that time was almost exclusively defined as prehospital emergency rescue, has evolved and now in-hospital domains have increasingly moved into the focus. At that time, the primary goal was to connect prehospital management with a smooth transition to hospital admission and further care in the hospital and to further optimize the rescue chain from the actual emergency through to causative treatment. Now after 15 years, the authors have critically assessed the development postulated in 2003 and reevaluated it. Which aspects could be developed further and become firmly established, what is still open and which questions in preclinical and clinical emergency treatment of the population will occupy us in the coming 15 years? With a critical eye to the past, the present contribution aims to capture the essential and new topics and open questions and provide a fresh perspective for the future of emergency medicine. Regulation at the state level or even lower levels of government often stand in contrast to more sweeping and economically effective approaches at the federal level. Prehospital emergency medicine in Germany is on the whole well-positioned with respect to facilities and personnel; however, as far as the economic situation and the utilization of available systems are concerned, there is still substantial room for improvement.

Advanced airway management in hoist and longline operations in mountain HEMS - considerations in austere environments: a narrative review This review is endorsed by the International Commission for Mountain Emergency Medicine (ICAR MEDCOM)

Background

Providing sufficient oxygenation and ventilation is of paramount importance for the survival of emergency patients. Therefore, advanced airway management is one of the core tasks for every rescue team. Endotracheal intubation is the gold standard to secure the airway in the prehospital setting. This review aims to highlight special considerations for advanced airway management preceding human external cargo (HEC) evacuations.

Methods

We systematically searched MEDLINE, EMBASE, and PubMed in August 2017 for articles on airway management and ventilation in patients before hoist or longline operation in HEMS. Relevant reference lists were hand-searched.

Results

Three articles with regard to advanced airway management and five articles concerning the epidemiology of advanced airway management in hoist or longline rescue missions were included. We found one case report regarding ventilation during hoist operations.

The exact incidence of advanced airway management before evacuation of a patient by HEC is unknown but seems to be very low (< 5%). There are several hazards which can impede mechanical ventilation of patients during HEC extractions: loss of equipment, hyperventilation, inability to ventilate and consequent hypoxia, as well as inadequacy of monitoring.

Conclusions

Advanced airway management prior to HEC operation is rarely performed. If intubation before helicopter hoist operations (HHO) and human cargo sling (HCS) extraction is considered by the rescue team, a risk/benefit analysis should be performed and a clear standard operating procedure (SOP) should be defined. Continuous and rigorous training including the whole crew is required. An international registry on airway management during HEC extraction would be desirable.

EMT-led laryngeal tube vs. face-mask ventilation during cardiopulmonary resuscitation - a multicenter prospective randomized trial

Background

Laryngeal tube (LT) application by rescue personnel as an alternate airway during the early stages of out-of-hospital cardiac arrest (OHCA) is still subject of debate. We evaluated ease of handling and efficacy of ventilation administered by emergency medical technicians (EMTs) using LT and bag-valve-mask (BVM) during cardiopulmonary resuscitation of patients with OHCA.

Methods

An open prospective randomized multicenter study was conducted at six emergency medical services centers over 18 months. Patients in OHCA initially resuscitated by EMTs were enrolled. Ease of handling (LT insertion, tight seal) and efficacy of ventilation (chest rises visibly, no air leak) with LT and BVM were subjectively assessed by EMTs during pre-study training and by the attending emergency physician on the scene. Outcome and frequency of complications were compared.

Results

Of 97 eligible patients, 78 were enrolled. During pre-study training EMTs rated efficacy of ventilation with LT higher than with BVM (66.7% vs. 36.2%, p = 0.022), but efficacy of on-site ventilation did not differ between the two groups (71.4% vs. 58.5%, p = 0.686). Frequency of complications (11.4% vs. 19.5%, p = 0.961) did not differ between the two groups.

Conclusions

EMTs preferred LT ventilation to BVM ventilation during pre-study training, but on-site there was no difference with regard to efficacy, ventilation safety, or outcome. The results indicate that LT ventilation by EMTs during OHCA is not superior to BVM and cannot substitute for BVM training. We assume that the main benefit of the LT is the provision of an alternative airway when BVM ventilation fails. Training in BVM ventilation remains paramount in EMT apprenticeship and cannot be substituted by LT ventilation.

Can we rely on out-of-hospital blood samples? A prospective interventional study on the pre-analytical stability of blood samples under prehospital emergency medicine conditions

Background

Prehospital intravenous access provides the opportunity to sample blood from an emergency patient at the earliest possible moment in the course of acute illness and in a state prior to therapeutic interventions. Our study investigates the pre-analytical stability of biomarkers in prehospital emergency medicine and will answer the question whether an approach of blood sampling out in the field will deliver valid laboratory results.

Methods

We prepared pairs of blood samples from healthy volunteers and volunteering patients post cardio-thoracic surgery. While one sample set was analysed immediately, the other one was subjected to a worse-than-reality treatment of 60 min time-lapse and standardized mechanical forces outside of the hospital through actual ambulance transport. We investigated 21 parameters comprising blood cells, coagulation tests, electrolytes, markers of haemolysis and markers of cardiac ischemia. Bland-Altman analysis was used to investigate differences between test groups. Differences between test groups were set against the official margins of test accuracy as given by the German Requirements for Quality Assurance of Medical Laboratory Examinations.

Results

Agreement between immediate analysis and our prehospital treatment is high as demonstrated by Bland-Altman plotting. Mechanical stress and time delay do not produce a systematic bias but only random inaccuracy. The limits of agreement for the tested parameters are generally within clinically acceptable ranges of variation and within the official margins as set by the German Requirements for Quality Assurance of Medical Laboratory Examinations.

Discussion

We subjected blood samples to a standardized treatment marking a worse-than-reality scenario of prehospital time delay and transport. Biomarkers including indicators of myocardial ischemia showed high pre-analytical stability.

Conclusion

We conclude the validity of blood samples from a prehospital environment.

[Preclinical fibrinolysis in patients with ST-segment elevation myocardial infarction in a rural region]

BACKGROUND

In the current guidelines for the treatment of patients with ST-segment elevation myocardial infarction (STEMI), the European Society of Cardiology (ESC) recommends preclinical fibrinolysis as a reperfusion therapy if, due to long transportation times, no cardiac catheterisation is available within 90-120 min. However, there is little remaining in-depth expertise in this method because fibrinolysis is presently only rarely indicated.

METHODS

In a rural area in southwestern Germany, where an emergency primary percutaneous coronary intervention was not routinely available within 90-120 min, 156 STEMI patients underwent fibrinolysis with the plasminogen activator reteplase, performed by trained emergency physicians. The practicality of the treatment, as well as complications and the mortality of the patients in the preclinical phase until arrival at the hospital, were retrospectively studied.

RESULTS

The mean time from onset of the symptoms to first medical contact was 114 ± 116 min. The mean interval to the start of fibrinolysis of 13.5 ± 6.4 min was within the 30 min mandated by the ESC. Patients with inferior STEMI represented the largest subgroup. Occurring in 39 cases (25 %), complications due to infarction were relatively common during the prehospital phase, including 15 cases (9.6 %) of cardiogenic shock, but in all cases the complications were manageable. No patient died before arrival at the hospital. As lysis-associated adverse effects, merely two uncomplicated mucosal haemorrhages and one case of mild allergic skin reactions were seen.

CONCLUSION

In emergency situations with long transportation times to the nearest suitable cardiac catheterisation laboratory, preclinical fibrinolysis in STEMI still represents a workable method. Success of this strategy requires particularly strong training of the emergency physicians in ECG and lysis therapy, and co-operation with nearby cardiac centres.

German critical incident reporting system database of prehospital emergency medicine: Analysis of reported communication and medication errors between 2005-2015

BACKGROUND

Communication failure in prehospital emergency medicine can affect patient safety as it does in other areas of medicine as well. We analyzed the database of the critical incident reporting system for prehospital emergency medicine in Germany retrospectively regarding communication errors.

METHODS

Experts of prehospital emergency medicine and risk management screened the database for verbal communication failure, non-verbal communication failure and missing communication at all.

RESULTS

Between 2005 and 2015, 845 reports were analyzed, of which 247 reports were considered to be related to communication failure. An arbitrary classification resulted in six different kinds: 1) no acknowledgement of a suggestion; 2) medication error; 3) miscommunication with dispatcher; 4) utterance heard/understood improperly; 5) missing information transfer between two persons; and 6) other communication failure.

CONCLUSION

Communication deficits can lead to critical incidents in prehospital emergency medicine and are a very important aspect in patient safety.
