The Advanced Critical Illness Life Support (ACiLS) course was developed on behalf of the German Society for Interdisciplinary Emergency and Acute Medicine (DGINA). The goal of the ACiLS course is to provide a nationally recognized and certified life support course that teaches medical professionals the key principles of initial care of critically ill patients in the emergency department, including the (PR_E-)AUD2IT-algorithm. It is designed for interdisciplinary and multi-professional staff in the resuscitation room to optimize patient safety and outcome. ACiLS includes a new blended learning concept with a theoretical part as comprehensive e-learning and a two-day practical part with strong focus on team training in scenarios and workshops. The course format was conceived to balance best teaching practices within the limited instructional time and resources available. This article describes the development of the ACiLS course and provides an overview of its future implementation.
Background and Rationale for the Educational Activity Innovation
Critically ill patients are stabilized by emergency medical services (EMS) and subsequently admitted to emergency department (ED) (1, 2). Early recognition of the underlying medical problem and appropriate treatment after arrival at the ED is a prerequisite in order to improve the outcome. Like the Advanced Trauma Life Support (ATLS®) and the European Trauma Course (ETC®) for severely injured patients, critically ill patients with non-traumatic conditions are often transferred directly to the resuscitation room as a dedicated treatment area in a German ED (1).
The non-trauma critically ill patients treated in the ED's resuscitation room have a wide variety of underlying diseases (1). In contrast to trauma patients (3, 4), information on the epidemiology, early in-hospital care, and diagnostic procedures for non-trauma critical ill patients in the ED is sparse (1, 5). There is evidence that critically non-trauma patients are more often treated than trauma patients in the resuscitation room [relation 4:1 (6)], and these patients have an approximately 3-fold higher mortality than trauma patients who receive care in the trauma bay (1, 5).
Some studies have recently presented data on the initial care of non-trauma critically ill patients (1, 5). The wide spectrum of underlying diseases is distributed according to ABCDE-problems as follows: 3, 29, 35, 32, and 1%, respectively (1, 5). The average duration of treatment in the resuscitation room was 33 ± 23 min and a relevant number of patients required intensive care treatment in the ED due to delayed transfer to an intensive care unit (ICU). Various critical interventions take place in the resuscitation room. Over 80% of these patients were admitted to the ICU. The 30-day mortality rate was 34–36% (1, 5).
According to the results of a recent survey among medical directors of German EDs (7), 84% stated that a specialized training program for non-trauma critically ill patients for physicians and nurses working in German EDs is urgently needed. Already established course concepts like ATLS® and ETC® are specialized for trauma patients, others like Advanced Life Support (ALS), Advanced Cardiac Life Support (ACLS) or Advanced Medical Life Support (AMLS®) do not focus on resuscitation room care.
The course concept “Advanced Critical Illness Life Support” (ACiLS) is developed on the initiative of the German Society of Interdisciplinary Emergency and Acute Medicine (DGINA) to structure the care of these patients and to implement a uniform course concept in addition to the existing life support courses in Germany.
Pedagogical Framework and Principles of the ACiLS Course Concept
Aims and Objectives
The aim of the ACiLS course is to teach healthcare professionals the key principles of acute care for critically ill patients in an interdisciplinary and multi-professional team approach that reflects the current way critically ill patients are treated in the resuscitation room in German EDs.
The content should cover the immediate differential diagnosis and therapy of the most important and most frequent tracer diagnoses in critically ill non-trauma patients as well as theoretical, practical and communicative skills.
The (PR_E-)AUD2IT algorithm (8), a standardized and easy-to-learn concept for the treatment of critically ill non-trauma patients, should be used as a backbone and key element of the course concept.
Targeted Professionals
The ACiLS course is primarily aimed at physicians and nurses from all specialties who are involved in the management of critically ill non-trauma patients in the ED's resuscitation room.
Concept and Development
At the beginning of 2020, the project group' ACiLS course concept' was formed within the working group “resuscitation room” of the DGINA. The project group consisted of a total of 40 physicians and nurses with high expertise in clinical emergency medicine and especially resuscitation room care. All aspects of the developed course concept were approved iteratively in numerous consensus conferences by the entire project group. A core group coordinated the global course development, several subgroups for scenarios, workshops and the e-learning part were founded and brought together to periodical online meetings. Despite the current corona pandemic, all participants met under appropriate safety precautions in October 2021 for a rehearsal of the practical part of the course. Table 1 descripted the course development according to Kern's 6-step approach (9, 10).
Table 1. “Advanced Critical illness Life Support” course curriculum development using Kern's 6-step framework.
Course Components
The ACiLS course is an interprofessional blended learning format that provides a standardized management concept in a team approach. Nurses and emergency physicians run through an e-learning-part consisting of 12 modules for theoretical content, which is completed by a pre-course exam and is scheduled at least 4 weeks before attending the 2-day face-to-face course. As a result of this split-up, the in-person part of the ACiLS course has a very high proportion of practical experience, yet does not neglect the theoretic foundation of emergency medicine.
The 2-day practical part includes, among other things, impulse lectures, team training in small groups based on simulated cases/scenarios, and the teaching of modern emergency procedures at appropriate skill stations.
The (PR_E-)AUD2IT-Algorithm
The (PR_E-)AUD2IT-algorithm (8) is the central didactic element of the course system and offers a mnemonic for a structured diagnostic and treatment (Table 2 and Supplementary Figure S1). As is well known from trauma that a structured algorithm for care in the resuscitation room improves the outcome (3). Therefore, the (PR_E-)AUD2IT algorithm was developed, incorporating proven components such as the “ABCDE” - approach, primary and secondary survey, fixed reassessments, and others. The implementation of the ACiLS course system and the (PR_E-)AUD2IT algorithm will be evaluated in the future, especially in terms of survival of non-traumatic critically ill patients, to verify the benefit of structured resuscitation room management for non-traumatic critically ill patients. Even if it is not yet finally planned, a scientific approach in the outcome comparison may be a before-and-after-study in a given time interval after introduction of the (PR_E-)AUD2IT algorithm in monocentric or multicenter investigations in non-traumatic critically ill patients. The concrete implementation of the scientific investigation is currently still part of a continuous development in this field.

Pedagogical Format
Part I: E-Learning for Preparation
After registration, the participant receives access data for the asynchronous e-learning. At least 4 weeks preceeding the face-to-face course, the participants have to work on 12 modules. The 1-h-modules provide the theoretical background, scientific foundations and practical knowledge of management in critically ill patients (diagnosis, clinical reasoning, basic algorithm, principles of crew resource management) using texts, interactive learning material and videos. They come along with facultative lessons that lead to deeper understanding and considering the various experience of the target group. All lessons consider current guideline recommendations and refer to corresponding links.
In addition, participants are introduced to leading symptom-oriented diagnostic cards specially developed for the ACiLS course. A hard copy of the card set is intended to support decision-making in the simulated cases (Supplementary Figure S2).
The e-learning is completed by a multiple-choice test after finishing all parts (passing limit: 70% of correct answers). Successful participation of the e-learning is mandatory for the in-person part of the course, but the participants are allowed to take unlimited attempts. The content of the e-learning chapters is given in more detail in Table 3 and Supplementary Figure S3.
Table 3. E-learning part of the “Advanced Critical illness Life Support” course.
Face-To-Face Course: 2 Days of ACiLS
The practical part of the course lasts two full days and includes eleven brief lectures, one faculty presented demonstration of the (PR_E-)AUD2IT-algorithm, 16 hands-on scenarios with relevant life-threatening emergencies in a ED's resuscitation room setting, and 6 workshops on skills, communication and procedures (Table 4). Cardiopulmonary resuscitation is not part of the course, since this topic is in detail addressed in other courses like the ALS course.
Table 4. Pedagogical elements of the “Advanced Critical illness Life Support” course.
The course is designed for 24 candidates (in four groups), and a minimum of eight instructors. The lectures with 110 min (12% of instruction time) represent only a small part of the in-person part, and repeat and emphasize the central points of the e-learning part. The scenario trainings and workshops cumulate to 625 min (66% of instruction time) and are the core educational elements of the ACiLS course (Table 5).
Table 5. Course schedule “Advanced Critical illness Life Support” course.
Each scenario training and workshop involves an instructor-participant ratio of 1:3. Of the six participants, one takes the role of a team leader, and the remainder assume the other three basic team member positions (two nurses, one physician). Two remaining participants act as observers. Roles are rotated in each scenario so that each candidate has the opportunity to take each position within the team.
Each scenario and workshop includes a team briefing, a non-trauma case with a life-threatening emergency, including application of the (PR_E-)AUD2IT-algorithm, and a subsequent feedback as a learning conversation. The work off of the (PR_E-)AUD2IT-algorithm addresses management, communication, and leadership issues common to resuscitation of critically ill non-trauma patients. Practice is given in prioritizing resuscitation efforts, delegating tasks, recognizing potential warning signs (red flags), and communicating with other relevant disciplines.
Each scenario is concluded with feedback from the instructors, where learning points and team performance are reviewed. This modular, scenario and workshop-based training represents a new and innovative development in medical education, providing instructions in the core principles of resuscitation and the associated management of critically ill non-trauma patients.
After each simulated scenario, the trainers facilitate a detailed debriefing in which the key learning points are discussed using the diagnosis cards. The debriefings also analyze the communication and interaction between the team members based on the principles of crew resource management.
As demonstrated in the OBSERvE studies (1, 5), patient's handover, initial stabilization, and emergency skills (e.g., airway management, ventilation, ultrasound) are commonly encountered in resuscitation room management. The workshops were designed based on these commonly requested emergency skills to prepare participants and provide a basic knowledge for all professionals. Noninvasive ventilation, patient's handover, ultrasound (modified RUSH protocol), electrical cardioversion and transcutaneous pacemaker therapy, and structured debriefing are topics covered in the workshops of the ACiLS course, which are a sampling of commonly used skills in the resuscitation room. Resuscitation training is explicitly not included, as other course concepts such as ALS or ACLS focus on cardiopulmonary resuscitation and periarrest situations. The ACiLS course can be seen as a complementary qualification to ALS or ACLS, with the two courses having different emphases.
Assessment of Candidates
The instructors continuously assess the participant‘s progress throughout the whole course within the scenario trainings and the workshops to provide personalized feedback. This continuous assessment allows instructors to identify the need for additional support and individual needs, and supports the participants to learn at their own pace. Personal mentoring is maintained throughout the course and supplemented by short meetings within the groups (mentoring groups). At the end of the second day, the candidates undergo a written final examination.
Material
All scenarios and workshops use resuscitation manikins (AmbuMan® Advanced, Ambu, Bad Nauheim, Germany) in combination with a simulation software (Skillqube®, Skillqube, Rauenberg, Germany) and the usual equipment available as identified in a recent survey (7). All material for the scenarios and workshops is standardized and presented using tablets (iPAD, Apple Inc., Germany).
The e-learning software is based on ARTICULATE 360 (Articulate Global, LLC) and organized by Notfall-Campus.de, the education site of DGINA e.V. Germany.
Language
The e-learning online part and the teaching material to date is written in German. The event language is German.
Implementation and Future Perspective
In June 2022, the core group set as potential future instructors will run through a test course with three instructors and 10 participants. A subsequent inauguration course with 10 instructors who attended the test course the days before and 18 participants will be the first real-time ACiLS course, held at the Malteser Bildungszentrum Euregio in Aachen, Germany as an established education center to train all forthcoming instructors.
The further perspective would be expanding to other course centers in Germany from 2023, according to a special catalog of requirements. An international ACiLS course is not yet finally planned, but a corresponding implementation will be evaluated after initial start in Germany.
Discussion
The present overview is the first description of the interdisciplinary and interprofessional ACiLS course concept, which contains some novel and remarkable features. The blended learning with modular content for theoretical background facilitates an individual learning process and a high proportion of practical education with workshop and scenario training in the two-day face-to-face-course. The course concept unites all members of the resuscitation room management, nurses as well as physicians.
The necessity of developing a separate training concept for non-trauma critically ill patients was firstly published in 2014 (11). There is a great need for a structured training concept both against the background of the patient volume, and from the perspective of those nurses and physician working in the ED (7).
Contrary to trauma management courses [e.g., ATLS® (12–14), ETC® (15, 16)], there are no structured care concepts for critically ill non-traumatic patients in the ED resuscitation room. The ACiLS course is not intended to replace established ALS and AMLS® courses, but to complement them. Rather, ALS courses are a basic requirement for participation in the ACiLS course.
On the one hand, there are courses for teaching basic and advanced measures of cardiopulmonary resuscitation, and on the other hand, there are courses for treating trauma patients (Supplementary Table S1). The AMLS course concept comes closest to our ACiLS course system, but its content is adapted for most out-of-hospital Emergency Medical Service (EMS) systems with training of two-person teams, but not for the resuscitation room of an ED specifically in Germany and not nearly as profound in the acute and emergency care of non-traumatic critically ill patients. It is the deficit of a suitable course concept that goes far beyond existing courses for cardiopulmonary resuscitation with a special focus on non-traumatic critically ill patients that has led to the development of the ACiLS course concept. Even established Crew Resource Management (CRM) course concepts deal intensively with only one aspect of the ACiLS course concept.
The (PR_E-)AUD2IT-algorithm (8) is used as a backbone of the structured emergency care concept, however, the algorithm has not been scientifically studied and there are no studies demonstrating a survival benefit. Future studies has to investigate whether patients treated using the (PR_E-)AUD2IT-algorithm as a structured treatment and diagnostic pathway receive better care than patients treated without the algorithm.
In conclusion, over a 3-year period, an interdisciplinary and multi-professional group of German specialists in the field of emergency and acute care and education developed a modular training system for critically ill patients. The ACiLS course system includes the (PR_E-)AUD2IT-algorithm, uses adult learning techniques, and focusses on scenario and workshop-based training for physicians and nurses. The emphasis on hands-on activities allows for a successful and modern training design, and meets the latest requirements in adult education. The ACiLS course is complementary to established lifesaving courses and is one important piece in the implementation of a nationwide, structured and standardized management of non-traumatic critically ill patients.
