Recent trends in simulation for obstetric anesthesia

The importance of simulation-based multi professional training in obstetric anesthesia: an update

PURPOSE OF REVIEW

Simulation-based training remains an integral component of medical education by providing a well tolerated, controlled, and replicable environment for healthcare professionals to enhance their skills and improve patient outcomes. Simulation technology applied to obstetric anesthesiology continues to evolve as a valuable tool for the training and assessment of the multidisciplinary obstetric care team.

RECENT FINDINGS

Simulation-based technology has continued to play a role in training and assessment, including recent work on interdisciplinary communication, recognition, and management of obstetric hemorrhage, and support in the low or strained resource setting. The COVID-19 pandemic has accelerated the evolution of simulation-based training away from a reliance on in-situ or high-fidelity manikin-based approaches toward an increasing utilization of modalities that allow for remote or asynchronous training.

SUMMARY

The evolution of simulation for interdisciplinary training and assessment in obstetric anesthesia has accelerated, playing a greater role in aspects of communication, management of hemorrhage and supporting low or strained resource settings. Augmented reality, virtual reality and mixed reality have advanced dramatically, spurred on by the need for remote and asynchronous simulation-based training during the pandemic.

Updates on Simulation in Obstetrical Anesthesiology Through the COVID-19 Pandemic

Simulation has played a critical role in medicine for decades as a pedagogical and assessment tool. The labor and delivery unit provides an ideal setting for the use of simulation technology. Prior reviews of this topic have focused on simulation for individual and team training and assessment. The COVID-19 pandemic has provided an opportunity for educators and leaders in obstetric anesthesiology to rapidly train health care providers and develop new protocols for patient care with simulation. This review surveys new developments in simulation for obstetric anesthesiology with an emphasis on simulation use during the COVID-19 pandemic.

Recent advances of simulation in obstetric anesthesia

PURPOSE OF REVIEW

Simulation training in obstetric anesthesia has become widespread in recent years. Simulations are used to train staff and trainees, assess and improve team performance, and evaluate the work environment. This review summarizes current research in these categories.

RECENT FINDINGS

Simulation to improve individual technical skills has focused on induction of general anesthesia for emergent cesarean delivery, an infrequently encountered scenario by anesthesia trainees. Low- and high-fidelity simulation devices for the learning and practicing neuraxial and non-neuraxial procedures have been described, and both are equally effective. The use of checklists in obstetric emergencies has become common as and post-scenario debriefing techniques have improved. Although participant task performance improves, whether participants retain learned skills or whether simulation improves patient outcomes has not yet been established. Tools to assess teamwork during simulation have been developed, but none have been rigorously validated. In-situ vs. offsite simulations do not differ in effectiveness.

SUMMARY

Simulation allows for practice of tasks and teamwork in a controlled manner. There is little data whether simulation improves patient outcomes and metrics to predict the long-term retention of skills by simulation participants have not been developed.

Medical Simulation as a Vital Adjunct to Identifying Clinical Life-Threatening Gaps in Austere Environments

BACKGROUND

Maternal mortality and morbidity are major causes of death in low-resource countries, especially those in Sub-Saharan Africa. Healthcare workforce scarcities present in these locations result in poor perioperative care access and quality. These scarcities also limit the capacity for progressive development and enhancement of workforce training, and skills through continuing medical education. Newly available low-cost, in-situ simulation systems make it possible for a small cadre of trainers to use simulation to identify areas needing improvement and to rehearse best practice approaches, relevant to the context of target environments.

METHODS

Nurse anesthetists were recruited throughout Sierra Leone to participate in simulation-based obstetric anesthesia scenarios at the country's national referral maternity hospital. All subjects participated in a detailed computer assisted training program to familiarize themselves with the Universal Anesthesia Machine (UAM). An expert panel rated the morbidity/mortality risk of pre-identified critical incidents within the scenario via the Delphi process. Participant responses to critical incidents were observed during these scenarios. Participants had an obstetric anesthesia pretest and post-test as well as debrief sessions focused on reviewing the significance of critical incident responses observed during the scenario.

RESULTS

21 nurse anesthetists, (20% of anesthesia providers nationally) participated. Median age was 41 years and median experience practicing anesthesia was 3.5 years. Most participants (57.1%) were female, two-thirds (66.7%) performed obstetrics anesthesia daily but 57.1% had no experience using the UAM. During the simulation, participants were observed and assessed on critical incident responses for case preparation with a median score of 7 out of 13 points, anesthesia management with a median score of 10 out of 20 points and rapid sequence intubation with a median score of 3 out of 10 points.

CONCLUSION

This study identified substantial risks to patient care and provides evidence to support the feasibility and value of in-situ simulation-based performance assessment for identifying critical gaps in safe anesthesia care in the low-resource settings. Further investigations may validate the impact and sustainability of simulation based training on skills transfer and retention among anesthesia providers low resource environments.

Improving Patient Safety through Simulation Training in Anesthesiology: Where Are We?

There have been colossal technological advances in the use of simulation in anesthesiology in the past 2 decades. Over the years, the use of simulation has gone from low fidelity to high fidelity models that mimic human responses in a startlingly realistic manner, extremely life-like mannequin that breathes, generates E.K.G, and has pulses, heart sounds, and an airway that can be programmed for different degrees of obstruction. Simulation in anesthesiology is no longer a research fascination but an integral part of resident education and one of ACGME requirements for resident graduation. Simulation training has been objectively shown to increase the skill-set of anesthesiologists. Anesthesiology is leading the movement in patient safety. It is rational to assume a relationship between simulation training and patient safety. Nevertheless there has not been a demonstrable improvement in patient outcomes with simulation training. Larger prospective studies that evaluate the improvement in patient outcomes are needed to justify the integration of simulation training in resident education but ample number of studies in the past 5 years do show a definite benefit of using simulation in anesthesiology training. This paper gives a brief overview of the history and evolution of use of simulation in anesthesiology and highlights some of the more recent studies that have advanced simulation-based training.

Progress in simulation education: developing an anesthesia curriculum

PURPOSE OF REVIEW

Simulation's role in anesthesia education is expanding to include more advanced skills and training for subspecialty practice. This review will provide an overview of many recent studies that expand the simulation curriculum for anesthesia education.

RECENT FINDINGS

Recent studies describe a curriculum that uses a range of simulation modalities, including part-task trainers, mannequin-based simulation, virtual reality, in-situ techniques, screen-based simulations as well as encounters with 'standardized' patients, nurses or physician colleagues. A variety of studies describe the use of task-training devises to more effectively acquire skills, such as fibre-optic intubation, ultrasound-guided regional anesthesia and transthoracic echocardiography as well as expand on a variety of teamwork skills particularly in subspecialty anesthesia practice.

SUMMARY

A curriculum is emerging that utilizes a variety of simulation modalities as part of a more comprehensive educational strategy for anesthesia specialty training.

Using simulation and standardized patients to teach vital skills to pain medicine fellows

INTRODUCTION

Simulation is an evolving aspect of medical education. The role of simulation in training programs is variable, however, in technical specialties such as surgery and anesthesiology its role is quickly becoming a standard part of training programs. Pain fellowship programs must teach clinical diagnostic skills, pharmacology and pathophysiology, in addition to interventional skills to fellows with varying residency backgrounds.

METHODS

The implementation of a hybrid simulation course into the pain fellowship curriculum allows for active learning as fellows experience challenging patient scenarios, stressful periprocedural events, and cases gone awry that require emergency algorithm recall and action.

CONCLUSION

This report describes the incorporation of simulation and crucial conversations into a pain fellowship curriculum.

Can simulation help to answer the demand for echocardiography education?

There has been a recent explosion of education and training in echocardiography in the specialties of anesthesiology and critical care. These devices, by their impact on clinical management, are changing the way surgery is performed and critical care is delivered. A number of international bodies have made recommendations for training and developed examinations and accreditations.The challenge to medical educators in this area is to deliver the training needed to achieve competence into already over-stretched curricula.The authors found an apparent increase in the use of simulators, with proven efficacy in improving technical skills and knowledge. There is still an absence of evidence on how it should be included in training programs and in the accreditation of certain levels.There is a conviction that this form of simulation can enhance and accelerate the understanding and practice of echocardiography by the anesthesiologist and intensivists, particularly at the beginning of the learning curve.

Anaesthesia in underdeveloped world: Present scenario and future challenges

The overall mortality and morbidity in underdeveloped countries are still unchanged and preventable risks factors constitute the main burden. Among these, anaesthesia-related mortality is largely preventable. Various contributory factors related to human resources, technical resources, education/teaching system and other utilities needs further attention in poor income group countries. Therefore, we have made an attempt to address all these issues in this educational article and have given special reference to those factors that might gain importance in (near) future. Proper understanding of anaesthesia-related resources, their overall impact on health care system and their improvisation methods should be thoroughly evaluated for providing safer anaesthesia care in these countries which would certainly direct better outcome and consequently influence mortality.
