RESUMO
BACKGROUND: Clinical skills training is an essential component of nursing education. However, sometimes education does not sufficiently prepare nurses for the real world. Virtual reality (VR) is an innovative method to complement existing learning strategies, yet few studies investigate its effectiveness. This study compared educational outcomes achieved by three groups learning with either of two different VR simulation variants, with varying technological features, or a video training on the endotracheal suctioning skill. METHODS: The investigated outcomes were knowledge and skill acquisition, learner satisfaction, and technology acceptance. 131 undergraduate nursing students were randomised into three groups, based on the interventions they received. Knowledge was assessed through a pre-post-test design, skill through a post-intervention objective structured clinical examination on a manikin, learning satisfaction and technology acceptance through standardised questionnaires, and qualitative feedback through focus groups. RESULTS: All interventions led to a significant knowledge acquisition, with no significant difference between the groups. The video intervention group performed significantly better than the VR groups in skill demonstration. One of the two VR intervention groups had a significantly higher learner satisfaction than the video group. Technology acceptance was high for both VR groups, with the simpler VR simulation resulting in higher technology acceptance than the one with more experimental features. Students described the VR experience as realistic, interactive, and immersive, and saw the opportunity to practise skills in a safe environment, learn from mistakes, and increase knowledge and confidence. CONCLUSIONS: For the development of VR trainings, we recommend keeping them simple and targeting a specific educational outcome since trying to optimise for multiple outcomes is resource intensive and hard to achieve. Psychomotor skills were easier for participants to learn by watching a video on the procedure rather than practically learning it with the VR hardware, which is a more abstract representation of reality. We therefore recommend using VR as a complementing resource to skills labs, rather than replacing existing learning strategies. Perhaps VR is not ideal for practising practical psychomotor skills at the moment, but it can increase knowledge, satisfaction, motivation, confidence and prepare for further practical training. TRIAL REGISTRATION: Not applicable.
RESUMO
OBJECTIVES: Simulation-based learning is widely used in nurse education, including virtual reality (VR) methods which have experienced a major growth lately. Virtual reality offers risk free and contactless learning. Currently, little is known about what topics of nursing are adopted for VR simulations and how their design meets various educational goals. This review aims to scope existing articles on educational VR nursing simulations, and to analyse approaches from didactic and technical perspectives. METHOD: A systematic mapping review following the PRISMA-ScR guideline and PICo search strategy was conducted. Peer reviewed articles in English and German were searched across Scopus, CINAHL, PsycINFO, PSYNDEX, PsycARTICLES, PubMed, ERIC and The Cochrane Library. Studies had to include at least one immersive head-mounted display VR simulation in the field of nursing education. Data extraction and analysis was performed in a narrative, graphical and tabular way. RESULTS: Twenty-two articles were identified. There is a large variety in the use and definition of VR simulation for educational purposes. Simulations were classified into four main educational objectives: procedural skills training to improve technical knowledge and proficiency; emergency response training that focusses on confidence; soft skills training that teaches empathy; and finally, psychomotor skills training. Various approaches and simulation designs were implemented to achieve these educational outcomes. A few of them were highly innovative in providing an immersive experience to learn complex tasks, e.g. auscultation, or foster empathy by mimicking life with dementia. CONCLUSIONS: Despite an increase in the use of state-of-the-art VR nursing simulations, there is still a paucity of studies on immersive HMD based VR scenarios. Researchers designing educational VR packages need to be clear on terminology. In order to make full use of VR, designers should consider including haptic devices to practise psychomotor skills and include social interaction to teach soft skills.
