National Implementation of In Situ Simulation-Based Training in Helicopter Emergency Medical Services: A Multicenter Study

The Royal Flying Doctor Service Initiation of Helicopter Video Simulation Orientation Training for Air Medical Crews in Western Australia: A Pilot Study

OBJECTIVE

In May 2022, the Royal Flying Doctor Service Western Operations in Western Australia pioneered the introduction of the first organizational helicopter emergency service with 2 Eurocopter EC145 helicopters. This article describes the pilot study undertaken, assessing the implementation and flight crew confidence outcomes of the supplementation of video simulation training to standard clinical training for helicopter air medical retrieval.

METHODS

Survey assessments using a 5-point Likert scale provided anonymous demographic data with summarized results of the means and standard deviations. Nonparametric tests were used to compare responses between the control and experimental groups from pretraining to postintervention to postpractical.

RESULTS

The findings showed an increase in confidence rates after a classroom session and further increases after a practical session in the control group. The intervention group showed a small rise in overall confidence levels after being shown video simulations following the completion of their classroom session before commencing their practical session. This study established that regardless of the airframe, clinical staff, often with significant experience in air medical retrieval and critical care medicine, do not automatically have confidence in performing critical care procedures in a new aircraft type to which they have not previously been oriented. The results display a statistically significant increase in confidence levels in procedural performance after the classroom session compared with the pretraining questionnaire, with a subtle further rise when video simulations are included in the classroom session. When a classroom session is subsequently supplemented with a practical simulation session, confidence levels continue to rise.

CONCLUSION

Implementing a comprehensive educational strategy including classroom and practical elements for clinical staff in their orientation to new aircraft improves their confidence in performing critical care procedures if required in flight. The addition of in-flight prerecorded videos demonstrating these critical care procedures is a useful adjunct to simulation training for flight crew in air medical retrieval, and further analytical studies may indeed show a statistically significant improvement in staff confidence.

Challenges to the implementation of in situ simulation at HEMS bases: a qualitative study of facilitators' expectations and strategies

INTRODUCTION

Facilitators play an essential role in simulation-based training on helicopter emergency medical services (HEMS) bases. There is scant literature about the barriers to the implementation of simulation training in HEMS. The purpose of this explorative interview study was to identify factors that the local facilitators anticipated would challenge the smooth implementation of the program, and their strategies to overcome these before the national implementation of in situ simulation-based training locally, and subsequently, one year after the programme was initiated, to identify the actual challenges they had indeed experienced, and their solutions to overcome these.

METHODS

A qualitative study with semi-structured group interviews of facilitators was undertaken before and after one year of simulation-based training on all HEMS bases and one Search and Rescue base. Systematic text condensation was used to extract facilitators' expectations and experiences.

RESULTS

Facilitators identified 17 themes in the pre-study-year interviews. Pedagogical, motivational and logistical issues were amongst the dominant themes. Other key themes included management support, dedicated time for the facilitators and ongoing development of the facilitator. In the post-study-year interviews, the same themes were identified. Despite anxiety about the perceptions of, and enthusiasm for, simulation training amongst the HEMS crews, our facilitators describe increasing levels of motivation over the study period.

CONCLUSION

Facilitators prognosticated the anticipated challenges to the successful implementation of simulation-based training on HEMS bases and suggested solutions for overcoming these challenges. After one year of simulation-based training, the facilitators reflected on the key factors for successful implementation.

Combining in-situ simulation and live HEMS mission facilitator observation: a flexible learning concept

BACKGROUND

Continuous medical education is essential in Helicopter Emergency Medical Services (HEMS). In-situ simulation training makes it possible to train in a familiar environment. The use of a dedicated facilitator is essential; however, when an in-situ simulation training session is interrupted by a live mission, the efforts invested in the training are left unfulfilled. This study aims to evaluate if HEMS mission observation and debriefing by the simulation facilitator is a feasible alternative to mission-interrupted simulation training, and how this alternative to simulation training is perceived by both facilitators and HEMS crew members.

METHODS

Facilitator observation during live missions and post-mission debriefing was offered as an alternative to mission-interrupted simulation training over a one-year period at three HEMS bases. Immediate feedback was requested from crews and facilitators after each observed live mission on a predefined questionnaire. At the end of the study period, semi-structured interviews were performed with a sample of HEMS crew members and facilitators to further explore the experience with the concept. Numerical data about the sessions were recorded continuously.

RESULTS

A total of 78 training sessions were attempted, with 46 (59%) of the simulations conducted as planned. Of the remaining, 23 (29%) were not started because the crew had other duties (fatigued crew or crew called for a mission where observation was inappropriate/impossible), and 9 (12%) training sessions were converted to observed live missions. In total, 43 (55%), 16 (21%) and 19 (24%) attempts to facilitate simulation training were undertaken on the three bases, respectively. The facilitators considered mission observation more challenging than simulation. The interviews identified local know-how, clinical skills, and excellent communication skills as important prerequisites for the facilitators to conduct live mission observation successfully. Participating crews and facilitators found simulation both valuable and needed. Being observed was initially perceived as unpleasant but later regarded as a helpful way of learning.

CONCLUSION

Live mission observation and debriefing seems a feasible and well-received alternative to an in-situ simulation program in HEMS to maximise invested resources and maintain the learning outcome. Furthermore, additional training of simulation facilitators to handle the context of live mission observation may further improve the learning output.
