Development of an Extended Reality Simulator for Basic Life Support Training.

ABSTRACT:

Objective

Extended Reality (XR) is a simultaneous combination of the virtual and real world. This paper presents the details of the framework and development methods for an XR basic life support (XR-BLS) simulator, as well as the results of an expert usability survey.

Methods

The XR-BLS simulator was created by employing a half-torso manikin in a virtual reality environment and using BLS education data that is in line with the 2020 American Heart Association guidelines. A head-mounted display (HMD) and hand-tracking device were used to perform chest compressions and ventilation and to enable the use of an automated external defibrillator in a virtual environment. A usability study of the XR-BLS simulator through an expert survey was also conducted. The survey consisted of a total of 8 items: 3, 2, and 2 questions about the ease of use of XR-BLS, delivery of training, and artificial intelligence (AI) instructor in the simulator, respectively.

Results

The XR simulator was developed, and the expert survey showed that it was easy to use, the BLS training was well delivered, and the interaction with the AI instructor was clear and understandable.

Discussion/conclusion

The XR-BLS simulator is useful as it can conduct BLS education without requiring instructors and trainees to gather.

Project description:BackgroundHealthcare providers, including medical students, should maintain their basic life support (BLS) skills and be able to perform BLS in case of cardiac arrest. Research shows that the use of virtual reality (VR) has advantages such as improved accessibility, practice with lifelike situations, and real-time feedback during individual training sessions. A VR BLS module incorporating these advantages, called Virtual Life Support, has been developed especially for the medical domain. Virtual Life Support was collaboratively developed by software developers and stakeholders within the field of medical education. For this study, we explored whether the first version of this module capitalised on the advantages of VR and aimed to develop an understanding of barriers to feasibility of use.MethodsThis study was conducted to assess the feasibility of employing Virtual Life Support for medical training and pinpoint potential obstacles. Four groups of stakeholders were included through purposive sampling: physicians, BLS instructors, educational experts, and medical students. Participants performed BLS on a BLS mannequin while using Virtual Life Support and were interviewed directly afterwards using semi-structured questions. The data was coded and analysed using thematic analysis.ResultsThematic saturation was reached after seventeen interviews were conducted. The codes were categorised into four themes: introduction, content, applicability, and acceptability/tolerability. Sixteen barriers for the use of Virtual Life Support were found and subsequently categorised into must-have (restraining function, i.e. necessary to address) and nice to have features (non-essential elements to consider addressing).ConclusionThe study offers valuable insights into redesigning Virtual Life Support for Basic Life Support training, specifically tailored for medical students and healthcare providers, using a primarily qualitative approach. The findings suggest that the benefits of virtual reality, such as enhanced realism and immersive learning, can be effectively integrated into a single training module. Further development and validation of VR BLS modules, such as the one evaluated in this study, have the potential to revolutionise BLS training. This could significantly improve both the quality of skills and the accessibility of training, ultimately enhancing preparedness for real-life emergency scenarios.

Project description:BackgroundSerious games enrich simulation-based health care trainings and improve knowledge, skills, and self-confidence of learners while entertaining them.ObjectiveA platform which can combine performance data from a basic life support (BLS) serious game app and hands-on data based on the same scoring system is not available in the market. The aim of this study was to create such a platform and investigate whether performance evaluation of BLS trainings would be more objective compared to conventional Objective Structured Clinical Examination (OSCE) examinations if these evaluations were carried out with the platform which combines OSCE scoring criteria with sensor data retrieved from the simulator's sensors.MethodsParticipants were 25 volunteers (11 men [44.0%] and 14 [56.0] women) among Acıbadem Mehmet Ali Aydınlar University students without prior knowledge of the BLS protocol. A serious game module has been created for teaching learners the European Resuscitation Council Basic Life Support 2015 protocol. A second module called the hands-on module was designed for educators. This module includes a checklist used for BLS OSCE examinations and can retrieve sensor data such as compression depth, compression frequency, and ventilation volume from the manikin (CPR Lilly; 3B Scientific GmbH) via Bluetooth. Data retrieved from the sensors of the manikin enable educators to evaluate learners in a more objective way. Performance data retrieved from the serious gaming module have been combined with the results of the hands-on module. Data acquired from the hands-on module have also been compared with the results of conventional OSCE scores of the participants, which were obtained by watching the videos of the same trainings.ResultsParticipants were considered successful in the game if they scored 80/100 or above. Overall, participants scored 80 or above in an average of 1.4 (SD 0.65) trials. The average BLS serious game score was 88.3/100 (SD 5.17) and hands-on average score was 70.7/100 (SD 17.3), whereas the OSCE average score was 84.4/100 (SD 12.9). There was no statistically significant correlation between success on trials (score ≥80/100), serious game, hands-on training app, and OSCE scores (Spearman rho test, P>.05). The mean BLS serious game score of the participants was 88.3/100 (SD 5.17), whereas their mean hands-on training app score was 70.7/100 (SD 17.3) and OSCE score was 84.4/100 (SD 12.9).ConclusionsAlthough scoring criteria for OSCE and hands-on training app were identical, OSCE scores were 17% higher than hands-on training app scores. After analyzing the difference of scores between hands-on training app and OSCE, it has been revealed that these differences originate from scoring parameters such as compression depth, compression frequency, and ventilation volume. These data suggest that evaluation of BLS trainings would be more objective if these evaluations were carried out with the modality, which combines visual OSCE scoring criteria with sensor data retrieved from the simulator's sensors.Trial registrationClinicalTrials.gov NCT04533893; https://clinicaltrials.gov/ct2/show/NCT04533893.

Project description:IntroductionPractical skills training is an essential part of medical education. An important example is the training of Basic Life Support (BLS) skills, which are key to improve patient outcomes in life-threatening situations. However, despite practical training, BLS performance is often sub-optimal even among healthcare professionals and medical students. Finding more effective training methods is therefore of high importance. A promising method to enhance learning outcomes is reflective practice. The goal of the present study was to evaluate whether a short reflective practice intervention following standard BLS training (Peyton's 4-step approach) improves BLS training outcomes, reflected in higher BLS performance and higher self-confidence to perform BLS.Method287 first-year medical students were randomly assigned to one of two BLS training conditions: 1) standard BLS training (ST), 2) ST followed by a 15-minute reflective practice exercise. Outcome parameters included objective BLS performance data assessed by a resuscitation manikin, and students' self-reported confidence in their BLS skills. Outcomes were assessed directly after the training (T0) and re-assessed one week later (T1). A two-way mixed model analysis of variance (ANOVA) was conducted to examine the effect of the intervention on BLS performance and self-reported confidence. Significance was determined by two-sided 95% confidence intervals.ResultsThe intervention group performed significantly more effective compressions at T1 and began significantly faster with performing their first chest compression at T0 and T1, in comparison to the control group. No significant differences between study groups regarding their self-reported confidence to perform BLS were observed.ConclusionThis research shows that standard BLS training accompanied with a simple, cost-effective reflective practice exercise can improve learners' BLS skill acquisition and retention. This shows that reflective practice has the potential to enhance practical skills training in medicine; yet, more empirical studies are needed to examine its broader applicability.
