Cardiac arrest in the perioperative period: a consensus guideline for identification, treatment, and prevention from the European Society of Anaesthesiology and Intensive Care and the European Society for Trauma and Emergency Surgery.

INTRODUCTION: Cardiac arrest in the operating room is a rare but potentially life-threatening event with mortality rates of more than 50%. Contributing factors are often known, and the event is recognised rapidly as patients are usually under full monitoring. This guideline covers the perioperative period and is complementary to the European Resuscitation Council guidelines. MATERIAL AND METHODS: The European Society of Anaesthesiology and Intensive Care and the European Society for Trauma and Emergency Surgery jointly nominated a panel of experts to develop guidelines for the recognition, treatment, and prevention of cardiac arrest in the perioperative period. A literature search was conducted in MEDLINE, EMBASE, CINAHL and the Cochrane Central Register of Controlled Trials. All searches were restricted to publications from 1980 to 2019 inclusive and to the English, French, Italian and Spanish languages. The authors also contributed individual, independent literature searches. RESULTS: This guideline contains background information and recommendation for the treatment of cardiac arrest in the operating room environment, and addresses controversial topics such as open chest cardiac massage, resuscitative endovascular balloon occlusion and resuscitative thoracotomy, pericardiocentesis, needle decompression, and thoracostomy. CONCLUSIONS: Successful prevention and management of cardiac arrest during anaesthesia and surgery requires anticipation, early recognition, and a clear treatment plan. The ready availability of expert staff and equipment must also be taken into consideration. Success not only depends on medical knowledge, technical skills and a well-organised team using crew resource management, but also on an institutional safety culture embedded in everyday practice through continuous education, training, and multidisciplinary co-operation.

Contributing factors are often known, and the event is recognised rapidly as patients are usually under full monitoring. This guideline covers the perioperative period and is complementary to the European Resuscitation Council (ERC) guidelines. MATERIAL AND METHODS: The European Society of Anaesthesiology and Intensive Care and the European Society for Trauma and Emergency Surgery jointly nominated a panel of experts to develop guidelines for the recognition, treatment and prevention of cardiac arrest in the perioperative period. A literature search was conducted in MEDLINE, EMBASE, CINAHL and the Cochrane Central Register of Controlled Trials.

The authors also contributed individual, independent literature searches. RESULTS: This guideline contains background information and recommendation for the treatment of cardiac arrest in the operating room environment, and addresses controversial topics such as open chest cardiac massage (OCCM), resuscitative endovascular balloon occlusion (REBOA) and resuscitative thoracotomy, pericardiocentesis, needle decompression and thoracostomy. CONCLUSION: Successful prevention and management of cardiac arrest during anaesthesia and surgery requires anticipation, early recognition and a clear treatment plan. The ready availability of expert staff and equipment must also be taken into consideration.

Just watching is not enough: Fostering simulation-based learning with collaboration scripts.

Aims: In addition to medical facts, medical students participating in simulation-based training are supposed to acquire general knowledge, e.g. heuristics to cope with critical incidents. While active participation is considered a major benefit of this kind of training, a large portion of students' time is often spent observing peers acting in the simulator. Thus, we instructionally supported learners with a collaboration script (i.e., a set of scaffolds that distribute roles and activities among learners in group learning situations) during observational phases of a simulation-based training. Our script was designed to help learners focus on heuristics and to facilitate more (inter-)active participation. We hypothesised that scripted learners would benefit from the instructional support with respect to individual and collaborative learning processes as well as individual learning outcomes. Methods: Thirty-four medical students in their 7th to 12th semester participated in this field study with control group design. The independent variable was the collaboration script (with/without). Four voluntary emergency courses with a full-scale simulator were examined. The acquisition of skills related to Crisis Resource Management (CRM) heuristics was one of the learning goals of these courses. The collaboration script induced learners to perform specific activities during and after each observational phase of the training. Further, the script sequenced the order of activities and assigned roles to the learners. Learning processes were measured on an individual level (by means of notes taken by learners during observational phases) and on a collaborative level (by means of learners' comments). Learning outcomes were measured with pre- and post-self-assessment of CRM skills and a brief video-based CRM skills test at the end of the course. Results: The collaboration script had the expected positive effect on individual and collaborative learning processes, leading to an increased focus on heuristic strategies and increased collaborative activity of scripted learners. There was no evidence that the experimental conditions differed regarding the objective measure of individual learning outcomes. However, self-assessment data revealed that students in the control condition perceived a higher improvement of CRM skills throughout the course. We suggest that our script might have helped learners adjust an illusion of their own competency - such an illusion may have appeared in the control group as a result of processing fluency. Conclusions: Findings suggest that simulation-based training in medical education can be enhanced with additional instructional support in the form of collaboration scripts designed to turn observational course phases into more active and better focused learning experiences.

Evaluation of simparteam - a needs-orientated team training format for obstetrics and neonatology.

INTRODUCTION: A standardized team-training program for healthcare professionals in obstetric units was developed based on an analysis of common causes for adverse events found in claims registries. The interdisciplinary and inter-professional training concept included both technical and non-technical skill training. Evaluation of the program was carried out in hospitals with respect to the immediate personal learning of participants and also regarding changes in safety culture. METHODS: Trainings in n=7 hospitals including n=270 participants was evaluated using questionnaires. These were administered at four points in time to staff from participating obstetric units: (1) 10 days ahead of the training (n=308), (2) on training day before (n=239), (3) right after training (n=248), and (4) 6 months after (n=188) the intervention. Questionnaires included several questions for technical and non-technical skills and the Hospital Survey on Patient Safety (HSOPS). RESULTS: Strong effects were found in the participants' perception of their own competence regarding technical skills and handling of emergencies. Small effects could be observed in the scales of the HSOPS questionnaire. Most effects differed depending on professional groups and hospitals. CONCLUSIONS: Integrated technical and team management training can raise employees' confidence with complex emergency management skills and processes. Some indications for improvements on the patient safety culture level were detected. Furthermore, differences between professional groups and hospitals were found, indicating the need for more research on contributing factors for patient safety and for the success of crew resource management (CRM) trainings.

Enhancing medical communication training using motion capture, perspective taking and virtual reality.

The aim of this work is to increase the effectiveness of real world medical training simulations by helping trainees gain a better understanding of the importance of communication and teamwork. Therefore we develop an online application which can be used together with real world simulations to improve training. To produce the online application we reconstructed two real world scenarios (one with students and one with practitioners) in an immersive virtual environment. Our application enables the trainees to view the scenario from different perspectives or to freely explore the environment. We aim to integrate it into the medical student curriculum at the University of Tübingen.

Education, teaching & training in patient safety.

Patient Safety is not a side-effect of good patient care by skilled clinicians. Patient safety is a subject on its own, which was traditionally not taught to medical personnel. This must and will dramatically change in the future. The 2010 Helsinki Declaration for Patient Safety in Anaesthesiology states accordingly "Education has a key role to play in improving patient safety, and we fully support the development, dissemination and delivery of patient safety training". Patient safety training is a multidisciplinary topic and enterprise, which requires us to cooperate with safety experts from different fields (e.g. psychologists, educators, human factor experts). Anaesthesiology has been a model for the patient safety movement and its European organisations like ESA and EBA have pioneered the field up to now: Helsinki Patient Safety Declaration and the European Patient Safety Course are the newest establishments. But Anaesthesiology must continue in its efforts in order to stay at the top of the patient safety movement, as many other disciplines gain speed in this topic. We should strive to fulfill the Helsinki Declaration and move even beyond that. As the European Council states: "Education for patient-safety should be introduced at all levels within health-care systems"

When things do not go as expected: scenario life savers.

In this paper we discuss scenario life savers - interventions before and during simulation scenarios that allow to create and use relevant learning opportunities, even if unexpected events happen during the conduction of the scenario. Scenario life savers are needed, when the comprehension or acceptance of the scenario by the participants is at stake, thus compromising learning opportunities. Scenario life savers can principally work by bringing participants back on track of the planned scenario or by adapting the conduction to their actions on the fly. Interventions can be within the logic of the scenario or from the "outside," not being part of the scenario itself. Scenario life savers should be anticipated during the design of scenarios and used carefully during their conduction, aiming to maximize the learning for participants.

[Incident reporting systems in anesthesiology--methods and benefits using the example of PaSOS]. / Incident Reporting in der Anästhesiologie - Hintergründe und Nutzen am Beispiel von PaSOS.

Preventing patient harm is one of the main tasks for the field of anesthesiology from early on. With the introduction of the national German incident reporting system PaSOS, which is hosted by the German anesthesia society, anesthesiology is again leading the field of patient safety. Important elements, success factors and background information for the introduction of successful incident reporting systems in an organization are given. Examples by and from PaSOS are given.

[Role playing as an essential element of simulation procedures in medicine]. / Rollenspiel als wesentliches Element bei Simulationsverfahren in der Medizin.

Role playing is an important element of virtually all simulation-based procedures. An improved understanding for methodological aspects facilitates its goal-oriented use in education and training, research and examinations. In the present paper we describe how different forms of role play are used in different simulation-based procedures. We describe a plausibility study from skills labs demonstrating that the introduction of role-playing can increase perceived realism. Finally we derive practical suggestions for the conduction of role plays in medical simulation.

Deepening the theoretical foundations of patient simulation as social practice.

Simulation is a complex social endeavor, in which human beings interact with each other, a simulator, and other technical devices. The goal-oriented use for education, training, and research depends on an improved conceptual clarity about simulation realism and related terms. The article introduces concepts into medical simulation that help to clarify potential problems during simulation and foster its goal-oriented use. The three modes of thinking about reality by Uwe Laucken help in differentiating different aspects of simulation realism (physical, semantical, phenomenal). Erving Goffman's concepts of primary frames and modulations allow for analyzing relationships between clinical cases and simulation scenarios. The as-if concept by Hans Vaihinger further qualifies the differences between both clinical and simulators settings and what is important when helping participants engage in simulation. These concepts help to take the social character of simulation into account when designing and conducting scenarios. The concepts allow for improved matching of simulation realism with desired outcomes. It is not uniformly the case that more (physical) realism means better attainment of educational goals. Although the article concentrates on mannequin-based simulations that try to recreate clinical cases to address issues of crisis resource management, the concepts also apply or can be adapted to other forms of immersive or simulation techniques.

Safety culture and crisis resource management in airway management: general principles to enhance patient safety in critical airway situations.

Airway management is a cornerstone of patient safety in anaesthesiology and in emergency and critical care medicine. Deficiencies in airway management could have catastrophic results for the patient. In anaesthesia patients, in particular, a high level of safety should be expected. It has been proven in other high-risk and complex industrial fields that obtaining very high levels of safety requires special strategies and safety philosophies in order to guarantee long-term low-risk production. The concept of safety culture has invaded many industries, more recently including medicine. Concepts of the high reliability organizations (HROs) are now ready to be adapted to medicine and offer promising improvements in health care. This paper applies some of the HRO principles to airway management and illustrates how to transform more general strategies to practical application in the clinical world. This includes the use of key elements of crisis resource management (CRM) and the development of a checklist for safety in airway management.
