This meta-analysis, without publication bias and with acceptable stability of results. The heterogeneity of virtual simulation on interprofessional collaboration is high (I2 = 90%), and the heterogeneity is improved after sensitivity analysis (I2 = 73%, p < 0.0001). 14 studies were analyzed by using the method of meta-analysis and the random effect model. The purpose was to study the effectiveness of virtual simulation in interprofessional collaboration and to investigate the influence of the number of specialties and the intervention duration on the effectiveness of interprofessional collaboration in virtual simulation teaching.
Question 1: Does virtual simulation effectively promote interprofessional collaboration?
This study comfirmed the value of virtual simulation in interprofessional collaboration. The overall effect value (Hedges's g) is 1.26 (95% CI: 0.54–1.26, p < 0.001). Virtual simulation can significantly promote interprofessional collaboration. The effect values before and after sensitivity analysis were all greater than 0.8.
For the measurement of related secondary variables, a total of 7 studies reported the attitude of team collaboration, among which 6 studies improved their attitude towards interprofessional collaboration after virtual simulation, and recognized the necessity of team collaboration. Students of different majors also have a better understanding of the roles of team members.
A total of three studies have reported communication skills, all of which show that communication skills have been significantly improved in a virtual simulation. Two studies reported improved self-efficacy. The dependency relationship among team members in collaboration can enhance the self-efficacy of team members when they complete complex tasks, and then stimulate high-level cognitive activities. (Ma Zhiqiang et al., 2021). Through effective cooperation with other professional members, students have enhanced their ability to solve problems and their sense of responsibility and reflection. Students may have a high degree of acceptance and satisfaction with virtual training.
Question 2: Is the effectiveness of virtual simulation in interprofessional collaboration affected by the number of professions?
The effect value of teams with two professions (MD = 1.64, 95% CI: 0.41–2.86) is greater than that of teams with more than two majors (MD = 0.66, 95% CI:-0.30–1.63). It can be inferred that the number of team professions affects the effect of interprofessional collaboration. Virtual simulation may have more advantages in teams with fewer professions.
Group size determines the interaction among peers.(Liu, Y.&Pásztor, A., 2022. )Group size sometimes affects the effectiveness of teamwork. Communication and collaboration in a larger team are more complicated than in a smaller group. This kind of complexity may mean that more information needs to be considered in team decision-making, and team tasks are more challenging and take longer time.
Differences in professions and team roles in interprofessional teams affect team cohesion, communication efficiency, and team decision-making. If the management or collaboration is improper, it may lead to the decrease of team effectiveness.
Question 3: Is the effectiveness of virtual simulation in interprofessional collaboration affected by the intervention duration?
The duration of intervention affects the effect of interprofessional collaboration. The effect value (MD = 1.76, 95% CI: 0.57–2.95) of more than one day is greater than that of less than one day (MD = 0.75, 95% CI:-0.51–2.00). With the longer intervention time, the effect of interprofessional team collaboration may be more significant.
There are significant differences in the influence of virtual experiment teaching on the learning effect of different learning duration (Tian Yuan & Zhou Xiaolei, 2021). For freshmen, working in groups with unfamiliar peers can be challenging (Jackson D et al.2014), especially in the first few weeks of study. Students must quickly acquire communication and teamwork skills to provide follow-up learning (Tidbury, L.et al. 2020).
Virtual simulation has the function of human-computer interaction. When an interprofessional team conducts virtual simulation, it needs to interact not only with team members but also with the virtual environment. In order to achieve effective teamwork, students should establish a reliable relationship with their peers, environment, and environment. In the virtual simulation, adaptation time must be provided to students.
In recent years, the number of related studies has been increasing, which indicates that academia are increasingly interested in interprofessional collaboration based on virtual simulation.
Based on the above research results, the following implications are obtained:
(1) It is more advantageous to carry out virtual experiment teaching in higher education.
The research target of this study is college students. The World Health Organization's Action Framework for Interprofessional Education and Cooperative Practice in 2010 demosntrated that students at the undergraduate level seem to be more receptive to IPL, which may involve various initiatives, including the use of mannequins or computer games for simulation-based learning (World Health Organization,2010). The effect value of primary school students and college students in virtual simulation experiments is not as good as that of college students (Wang Cixiao et al., 2022)
Virtual simulation brings enormous advantages to higher education. Virtual simulation can create a virtual environment similar to the actual operation scene, so that participants can experience the training environment visually and audibly, and have a strong sense of immersion, which is beneficial for students to devote themselves to the collaborative process. As an auxiliary teaching tool, it can meet students' learning needs to a greater extent and is conducive to the improvement of students' autonomous learning and collaborative learning ability across professional teams.
Therefore, this study suggests integrating interprofessional knowledge into undergraduate courses and strengthening the application of virtual simulation technology in interprofessional education in higher education.
(2)Constructing the mechanism of co-construction and sharing of virtual simulation teaching resources.
Socialism emphasizes the importance of social interaction in learning. Compared to individual learning, group learning can make learners have a deeper understanding of knowledge and experience more significance. In practical situations, students often need to cooperate with people outside their major, and the opportunities for students to cooperate with students from other majors in school are very limited. A virtual simulation system can meet the collaboration needs of our school and even more students. By constructing the co-construction and sharing mechanism of virtual simulation teaching resources, the utilization rate of virtual simulation teaching resources can be improved, so as to continuously improve the quality and level of students' interprofessional collaboration.
To promote the development of virtual simulation teaching and give full play to the advantages of virtual simulation, we should strengthen the construction of an open virtual simulation resource-sharing platform, effectively integrate virtual training teaching resources, centrally manage virtual simulation resources, improve the teaching and evaluation functions of virtual simulation, and provide timely teaching feedback. By constructing an open, shared and highly immersive virtual training environment, teaching resources can be co-built and shared, thus effectively solving the problems of students' online training and forming a higher level of the construction cycle.
(3) Broaden the application field of interprofessional collaboration practice.
Interprofessional education has broad prospects. In practice, students need to have the ability to interprofessional collaboration, so as to deal with various complex problems.
In the process of literature retrieval, it is found that most of the interprofessional education in higher education is in the medical field, and some are in other professional fields, such as architecture, aviation, geography, emergency management, and so on. Other professional fields should also carry out interprofessional collaborative practice.
From the trend point of view, the barriers between disciplines will gradually be broken down, and the educational model with structural ability as its core goal will become more and more important. Universities must re-evaluate their methods in medicine, law, public health, social work, public policy, and other professions (Joel Teitelbaum &Ellen Lawton, 2017).
We need to carry out more research, including situational analysis of the feasibility of interprofessional education and the effects of interprofessional education in other fields, to promote the development of interprofessional education and interprofessional collaborative practice.
