Simulation training for crises during venoarterial extracorporeal membrane oxygenation

ECMO simulation: How much, who to train, and a review of cost, fidelity and performance

BACKGROUND

Extracorporeal Membrane Oxygenation (ECMO) is a high-risk, low-volume procedure requiring repetition, skill and multiple disciplines with fidelity of communication. Yet many barriers exist to maintain proficiency and skills with variable cost and fidelity. We designed and implemented a low-cost monthly ECMO simulation and hypothesized providers would have increased familiarity and improved teamwork. We also review some key elements of cost, fidelity and evaluation of effectiveness.

METHODS

A structured, 1-hour ECMO simulation was performed on a customized mannikin on a monthly basis in 2022. Qualitative surveys were administered to each member post-simulation. Answers were categorized by theme, including satisfaction of patient care, evaluation of self and team dynamics, and areas for improvement.

RESULTS

Most participants were satisfied with their ability to take care of the patient, with common themes of communication and coordination of roles. Identified areas of improvement were mostly limited to technical skills, and soft skills such as communication and teamwork.

CONCLUSIONS

We designed and implemented a low-cost, monthly and multi-disciplinary ECMO simulation program with overall positive feedback and identified areas for improvement. There remains variability in cost, fidelity and evaluation of performance and retention. There may be a need to create guidelines for ECMO simulation training that can be applied at all institutions utilizing ECMO for patient care.

High fidelity ECMO simulation: a reality check with reality-use of simulation in ECMO teaching program

Simulation based learning is becoming a crucial part in ECMO education. Simulation can provide a safe but also very realistic learning experience depending on simulation fidelity. In our institution we developed a simulation based ECMO training program that incorporates low- and high-fidelity simulation. Aim of this study was to evaluate effectiveness of low- and high-fidelity simulation teaching strategies in ECMO novices. We conducted four consecutive ECMO training courses that included fifty-one ECMO novices. We describe ECMO training execution and evaluate training effectiveness and perception by structured pre- and post-training questionnaires analysis. Results of our study show extremely high satisfaction rate with simulation training (4.9 ± 0.3, Lickert 5 point scale). High-fidelity simulation was perceived as very realistic and as such represents an important tool in learning immersion and experience. However, participants reported significant decline from their expectations with regard to structured approach to troubleshooting (4.7 ± 0.5 vs 4.3 ± 0.7, p = 0.02) and efficiency improvement (4.7 ± 0.5 vs 4.3 ± 0.6, p = 0.002) after high-fidelity simulation. There was also a significant decline from their expectation on self-confidence improvement (4.7 ± 0.5 vs 4.2 ± 0.7, p = 0.001). Our results therefore show, that complex high-fidelity simulation should probably be used with caution in novice participants, not to discourage them from further learning.

Extracorporeal cardiopulmonary resuscitation in adults and children: A review of literature, published guidelines and pediatric single-center program building experience

Extracorporeal cardiopulmonary resuscitation (ECPR) is an adjunct supportive therapy to conventional cardiopulmonary resuscitation (CCPR) employing veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in the setting of refractory cardiac arrest. Its use has seen a significant increase in the past decade, providing hope for good functional recovery to patients with cardiac arrest refractory to conventional resuscitation maneuvers. This review paper aims to summarize key findings from the ECPR literature available to date as well as the recommendations for ECPR set forth by leading national and international resuscitation societies. Additionally, we describe the successful pediatric ECPR program at Texas Children's Hospital, highlighting the logistical, technical and educational features of the program.

Acute limb ischemia after femoro-femoral extracorporeal life support implantation: a comparison of surgical, percutaneous or combined vascular access in 402 patients

BACKGROUND

Extracorporeal life support (ECLS) is a salvage treatment for acute circulatory failure. Our high-volume tertiary centre performs more than 100 implants annually and provides ECLS-transports. With this study, we aimed to analyse the incidence and risk factors of limb ischemia depending on the vascular access.

METHODS

Between January 1st 2007 and December 31st 2018, 937 patients received an ECLS. Preoperative, intraoperative, in-hospital and up to 5 years follow-up data was collected. Outcome measures were limb ischemia and survival.

RESULTS

In total, 402 femoro-femoral veno-arterial ECLS patients were identified. Mean age was 56±16.7years, 26.9% were female, 7.9% had a history of peripheral vascular disease. Cannulation was performed percutaneously in 82.1% (n=330), surgically in 5.7% (n=23) and combined in 12.2% (n=49). Mortality was not significantly different between the groups (51.1% percutaneous, 43.5% surgical, 44.9% combined (p=0.89)). There was no significant difference in limb ischemia either, but a trend towards an increased frequency in the percutaneous group (p=0.0501). No amputation was necessary. Limb ischemia slightly increased in-hospital mortality (54.6%) but did not affect long-term survival beyond 30 days. Univariate analysis adjusted for cannulation methods revealed younger age and female gender as risk factors of limb ischemia and younger age for limb ischemia after percutaneous cannulation.

CONCLUSIONS

Our study shows that percutaneous, surgical and combined vascular access techniques for ECLS implantation are associated with comparable and low incidence of limb ischemia which slightly increases in-hospital mortality. Special precaution has to be taken in young and female patients.

ECMO simulation training during a worldwide pandemic: The role of ECMO telesimulation

BACKGROUND

Extracorporeal membrane oxygenation (ECMO) is a supportive therapy used in the most severe forms of acute respiratory distress syndrome. Due to its intrinsic complexity and relatively low annual volume, simulation is essential for efficient and appropriate ECMO management. COVID-19 has limited the opportunities for high-fidelity in-person simulation training when many hospitals are looking to expand their ECMO services to battle the ongoing pandemic. To meet this demand, the National Cardiovascular Center Harapan Kita, Jakarta, Indonesia, conducted a 3-day ECMO course entailing online didactic lectures (adult and paediatric stream), water drills and telesimulation.

PURPOSE

The purpose of the study is to report the evaluation result of this novel model of education during COVID-19 outbreak.

DATA COLLECTION

Participants were given an ECMO knowledge pre-course and post-course test and a telesimulation evaluation survey at the conclusion and these data were collected.

RESULTS

The course was attended by 104 physicians, critical care nurses and perfusionists. Pre-course and post-course assessments showed a significant improvement in ECMO knowledge (60.0% vs 73.3%, respectively). Overall, the participants rated the telesimulation positively, and most found it acceptable to in-person simulation training considering the pandemic restrictions.

CONCLUSION

Despite the complexities of ECMO, our recent experience demonstrates ECMO education and simulation delivered online is feasible, welcomed and supportive of a change in ECMO training course format. As we incorporate more innovative digital technologies, telesimulation may further enhance the quality of future ECMO training.

Trends and Innovations of Simulation for Twenty First Century Medical Education

In the last two decades there has been an enormous growth in the use of clinical simulation. This teaching-learning methodology is currently the main tool used in the training of healthcare professionals. Clinical simulation is in tune with new paradigms in education and is consistent with educational theories that support the use of experiential learning. It promotes the development of psychomotor skills and strengthens executive functions. This pedagogical approach can be applied in many healthcare topics and is particularly relevant in the context of restricted access to clinical settings. This is particularly relevant considering the current crisis caused by the COVID-19 pandemic, or when trying to reduce the frequency of accidents attributed to errors in clinical practice. This mini-review provides an overview of the current literature on healthcare simulation methods, as well as prospects for education and public health benefits. A literature search was conducted in order to find the most current trends and state of the art in medical education simulation. Presently, there are many areas of application for this methodology and new areas are constantly being explored. It is concluded that medical education simulation has a solid theoretical basis and wide application in the training of health professionals at present. In addition, it is consolidated as an unavoidable methodology both in undergraduate curricula and in continuing medical education. A promising scenario for medical education simulation is envisaged in the future, hand in hand with the development of technological advances.

Human factors in ECLS - A keystone for safety and quality - A narrative review for ECLS providers

INTRODUCTION

Although the technology used for extracorporeal life support (ECLS) has improved greatly in recent years, the application of these devices to the patient is quite complex and requires extensive training of team members both individually and together. Human factors is an area that addresses the activities, contexts, environments, and tools which interact with human behavior in determining overall system performance.

HYPOTHESIS

Analyses of the cognitive behavior of ECLS teams and individual members of these teams with respect to the occurrence of human errors may identify additional opportunities to enhance safety in delivery of ECLS.

RESULTS

The aim of this article is to support health-care practitioners who perform ECLS, or who are starting an ECLS program, by establishing standards for the safe and efficient use of ECLS with a focus on human factor issues. Other key concepts include the importance of ECLS team leadership and management, as well as controlling the environment and the system to optimize patient care.

CONCLUSION

Expertise from other industries is extrapolated to improve patient safety through the application of simulation training to reduce error propagation and improve outcomes.

Comprehensive assessment of a nationwide simulation-based course for artificial life support

BACKGROUND

Successful implementation of medical technologies applied in life-threatening conditions, including extracorporeal membrane oxygenation (ECMO) requires appropriate preparation and training of medical personnel. The pandemic has accelerated the creation of new ECMO centers and has highlighted continuous training in adapting to new pandemic standards. To reach high standards of patients' care, we created the first of its kind, National Education Centre for Artificial Life Support (NEC-ALS) in 40 million inhabitants' country in the Central and Eastern Europe (CEE). The role of the Center is to test and promote the novel or commonly used procedures as well as to develop staff skills on management of patients needing ECMO.

METHOD

In 2020, nine approved and endorsed by ELSO courses of "Artificial Life Support with ECMO" were organized. Physicians participated in the three-day high-fidelity simulation-based training that was adapted to abide by the social distancing norms of the COVID-19 pandemic. Knowledge as well as crucial cognitive, behavioral and technical aspects (on a 5-point Likert scale) of management on ECMO were assessed before and after course completion. Moreover, the results of training in mechanical chest compression were also evaluated.

RESULTS

There were 115 participants (60% men) predominantly in the age of 30-40 years. Majority of them (63%) were anesthesiologists or intensivists with more than 5-year clinical experience, but 54% had no previous ECMO experience. There was significant improvement after the course in all cognitive, behavioral, and technical self-assessments. Among aspects of management with ECMO that all increased significantly following the course, the most pronounced was related to the technical one (from approximately 1.0 to more 4.0 points). Knowledge scores significantly increased post-course from 11.4 ± SD to 13 ± SD (out of 15 points). The quality of manual chest compression relatively poor before course improved significantly after training.

CONCLUSIONS

Our course confirmed that simulation as an educational approach is invaluable not only in training and testing of novel or commonly used procedures, skills upgrading, but also in practicing very rare cases. The implementation of the education program during COVID-19 pandemic may be helpful in founding specialized Advanced Life Support centers and teams including mobile ones. The dedicated R&D Innovation Ecosystem established in the "ECMO for Greater Poland" program, with developed National Education Center can play a crucial role in the knowledge and know-how transfer but future research is needed.
