Effectiveness of virtual patients in teaching clinical decision-making skills to dental students

Exploring medical students' perceptions of individual and group-based clinical reasoning with virtual patients: a qualitative study

BACKGROUND

Virtual Patients are computer-based simulations used to teach and evaluate patient interviews, medical diagnoses, and treatment of medical conditions. It helps develop clinical reasoning skills, especially in undergraduate medical education. This study aimed to and investigate the medical students' perceptions of individual and group-based clinical reasoning and decision-making processes by using Virtual Patients.

METHODS

The study group comprised 24 third-year medical students. Body Interact® software was utilized as a VP tool. The students' readiness and the courses' learning goals were considered when choosing the scenarios. Semi-structured interview forms were employed for data collection. MAXQDA 2020 qualitative analysis software was used to analyze the data. The students' written answers were analyzed using content analysis.

RESULTS

The participants perceived individual applications as beneficial when making clinical decisions with Virtual Patients, but they suggested that group-based applications used with the same cases immediately following individual applications were a more appropriate decision-making method. The results indicated that students learn to make decisions through trial and error, based on software scoring priorities, or using clinical reasoning protocols.

CONCLUSION

In group-based reasoning, the discussion-conciliation technique is utilized. The students stated that the individual decision-making was advantageous because it provided students with the freedom to make choices and the opportunity for self-evaluation. On the other hand, they stated that the group based decision-making process activated their prior knowledge, assisted in understanding misconceptions, and promoted information retention. Medical educators need to determine the most appropriate method when using Virtual Patients, which can be structured as individual and/or group applications depending on the competency sought.

Virtual counselling of tobacco cessation during the COVID-19 pandemic: A qualitative study on the experiences and perceptions of Malaysian dental undergraduates and their patients

INTRODUCTION

When dental institutions had to close down during the Movement Control Order (MCO) implementation due to the COVID-19 pandemic, dental students were faced with delays in completing their tobacco cessation schedule. An alternative was to allow students to conduct virtual counselling (VC) for smoking cessation for their patients to address their clinical requirements. This study aimed to explore Malaysian dental undergraduates' and patients' experiences undergoing smoking cessation counselling through virtual platforms.

MATERIALS AND METHODS

The study consisted of qualitative, semi-structured Focus Group Discussions (for students, n = 23) and in-depth interviews (for patients, n = 9); to phenomenologically describe the perceptions of participants involved in the VC. Each session was recorded with the participants' permission. The recorded session was transcribed verbatim and thematically analysed using the qualitative data analysis software, NVivo™.

RESULTS

The major themes that emerged were: (1) General opinions and experiences, (2) Content of VCs, (3) Remote access to counselling, (4) Patient-clinician relationships, (5) Technical issues, (6) Changes after VCs, and (7) Future application. Most students and patients were quite comfortable with VC as it is convenient, allowing students to be creative and avoid the hassle of transport and traffic. However, some of the students felt that it lacked the personal touch and guidance from lecturers who would normally be present during physical class.

CONCLUSION

Virtual counselling enables remote access to counselling, but it is also subjected to some limitations, especially regarding lack of clinical assessments, human touch and internet issues. Though participants were optimistic about adapting it in the future, multiple factors must be considered. Ultimately, the behavioural change will depend on the patient's motivation in making a difference.

Effectiveness of haptic feedback devices in preclinical training of dental students-a systematic review

BACKGROUND

Acquisition of psychomotor skills is of utmost importance for competent preclinical restorative dentistry. Recent advancements in haptic feedback technology have been incorporated into preclinical dental education to augment the conventional phantom head-based training.

OBJECTIVE

This systematic review aims to assess the effectiveness of haptic feedback device, Simodont, in improving the skill development and learning outcomes of dental students during their preclinical training.

MATERIALS AND METHODS

Electronic databases Web of Science, Scopus, PubMed were searched for relevant studies since inception up until March, 2023. Only English language studies that assessed the effectiveness of haptic feedback devices in preclinical dental education were included. We excluded studies that did not use Simodont as the haptic feedback device or did not involve preclinical restorative work. Study quality was assessed using the revised Cochrane risk of bias tool and ROBINS-I. The primary goal of the study is to evaluate the efficacy of Simodont as a complementary training modality for dentistry students.

RESULTS

Results from 9 high-quality studies were analyzed and synthesized to evaluate the overall impact of haptic feedback devices on various aspects of preclinical training. The studies were conducted on 826 undergraduate dental students enrolled in various years of their training across dental colleges and universities in different parts of the world. A majority of studies showed some concerns regarding risk of bias. Haptic feedback devices added a new layer to Virtual Reality (VR) through the perception of touch and force feedback. It assisted junior dental students improve their psychomotor skills and movement skills. Instantaneous feedback on the students' performance helped enhance their self-assessment and correction, and also eliminated the subjectivity of evaluation. Data derived from virtual simulators helped stratify dental students and predict their clinical performance, providing an opportunity to tailor the learning process to meet individual diversity in students' expertise.

CONCLUSION

Based on the limited evidence available, Simodont was effective in preclinical training of dental students, offering advantages such as unlimited reproducibility, objective evaluation of preparation by computer assessment, and cost reduction. And further studies are warranted to explore the incorporation of patient's oral environment simulation for better skill training.

Application of virtual reality in dental implants: a systematic review

BACKGROUND AND OBJECTIVE

A treatment approach that is widely used as a permanent and natural replacement for missing or extracted teeth is dental implants .VR is a computer-generated simulation that creates a three-dimensional (3D) image or environment. Advances in VR -based learning allow learners and students to practice and also help professionals plan a wide variety of surgical procedures, including the correct placement of dental implants. Therefore, in this systematic review, our aim was to investigate and evaluate the available virtual reality tools for dental implants and their effectiveness.

MATERIALS AND METHODS

Studies published up to 01/30/2023 which report the applications of using virtual reality technology in dental implants, were reviewed in three databases, including PubMed, Web of Science, and Scopus. All studies with evidence reporting the role of virtual reality technology in the field of dental implants were included in our analyses, written in English and published in peer-reviewed form, are included. Theoretical articles, and letters that did not provide original data, as well as studies that reported incomplete information, were excluded. Two reviewers independently assessed search results, extracted data, and assessed the quality of the included studies, and decisive agreement was reached by discussion and consultation with the third researcher. Narrative synthesis was undertaken to summarize and report the findings.

RESULTS

Out of 1633 initial search results, nine were included in the present study based on the inclusion criteria. The focus of seven studies was on teaching and learning, and two studies have examined the implant planning procedure. The most commonly used hardware and software were head-mounted display and Unity3D, respectively. In almost all studies, the results showed that the use of virtual reality-based systems improves and enhances the skills of users, including dental students and specialists.

CONCLUSIONS

Our findings showed that VR is an effective method for teaching and planning the implant process. Although the use of VR technology is limited for various reasons such as cost, it can increase the skills of dental professionals in performing dental implants.

Evaluating the Effectiveness of Interactive Virtual Patients for Medical Education in Zambia: Randomized Controlled Trial

BACKGROUND

Zambia is facing a severe shortage of health care workers, particularly in rural areas. Innovative educational programs and infrastructure have been established to bridge this gap; however, they encounter substantial challenges because of constraints in physical and human resources. In response to these shortcomings, strategies such as web-based and blended learning approaches have been implemented, using virtual patients (VPs) as a means to promote interactive learning at the Levy Mwanawasa Medical University (LMMU) in Zambia.

OBJECTIVE

This study aimed to evaluate the students' knowledge acquisition and acceptance of 2 VP medical topics as a learning tool on a Zambian higher education e-learning platform.

METHODS

Using a mixed methods design, we assessed knowledge acquisition using pre- and posttests. In a randomized controlled trial setting, students were assigned (1:1) to 2 medical topics (topic 1: appendicitis and topic 2: severe acute malnutrition) and then to 4 different learning tools within their respective exposure groups: VPs, textbook content, preselected e-learning materials, and self-guided internet materials. Acceptance was evaluated using a 15-item questionnaire with a 5-point Likert scale.

RESULTS

A total of 63 third- and fourth-year Bachelor of Science clinical science students participated in the study. In the severe acute malnutrition-focused group, participants demonstrated a significant increase in knowledge within the textbook group (P=.01) and the VP group (P=.01). No substantial knowledge gain was observed in the e-learning group or the self-guided internet group. For the appendicitis-focused group, no statistically significant difference in knowledge acquisition was detected among the 4 intervention groups (P=.62). The acceptance of learning materials exhibited no substantial difference between the VP medical topics and other learning materials.

CONCLUSIONS

In the context of LMMU, our study found that VPs were well accepted and noninferior to traditional teaching methods. VPs have the potential to serve as an engaging learning resource and can be integrated into blended learning approaches at LMMU. However, further research is required to investigate the long-term knowledge gain and the acceptance and effectiveness of VPs in medical education.

Synchronous online lecturing or blended flipped classroom with jigsaw: an educational intervention during the Covid-19 pandemic

BACKGROUND

The Covid-19 pandemic has changed the education system throughout the world. This study aimed to compare synchronous online lecturing with blended flipped classroom plus jigsaw in terms of their effects on the students' learning, communication skills and critical thinking disposition.

METHODS

This is an educational intervention conducted at the Nursing and Midwifery School of Shiraz University of Medical Sciences. Two incoming students of nursing and midwifery were selected by complete enumeration. Then synchronous online lecturing was given to one group (n = 40) and blended flipped classroom and jigsaw to the other (n = 44). After that, given the prevailing conditions, both methods were performed fully online. Then Participants completed an online questionnaire. A researcher-made learning questionnaire, the Interpersonal Communication Skills Questionnaire developed by Fetro, and Ricketts' Critical Thinking Disposition Inventory were used to assess the study variables.

RESULTS

The mean learning scores in the blended group were slightly higher but this difference was not significant (P = 0.767). In the blended group, the mean scores of communication skills were significantly higher after the intervention in all the dimensions, except for empathy & intimacy and listening skills. In the online lecture group, there was no significant difference between before and after the intervention. Communication skills (P < 0.001) scored significantly higher in the blended group after the intervention than that in the synchronous online lecturing group in all the dimensions except for empathy & intimacy. In the online lecture group, there was no significant difference in critical thinking disposition between before and after the intervention. In the blended group, the overall score of critical thinking disposition and its dimensions was significantly higher after the intervention (P < 0.001), except for the perfection dimension. There was no significant difference between the two groups in terms of the mean total score of critical thinking disposition and its dimensions before and after the intervention.

CONCLUSION

Given the global circumstances, the blended method was more effective in promoting learning outcomes and communication skills than synchronous online lectures. Furthermore, it seems that this new approach could improve critical thinking.

Using a Virtual Patient via an Artificial Intelligence Chatbot to Develop Dental Students’ Diagnostic Skills

Knowing how to diagnose effectively and efficiently is a fundamental skill that a good dental professional should acquire. If students perform a greater number of clinical cases, they will improve their performance with patients. In this sense, virtual patients with artificial intelligence offer a controlled, stimulating, and safe environment for students. To assess student satisfaction after interaction with an artificially intelligent chatbot that recreates a virtual patient, a descriptive cross-sectional study was carried out in which a virtual patient was created with artificial intelligence in the form of a chatbot and presented to fourth and fifth year dental students. After several weeks interacting with the AI, they were given a survey to find out their assessment. A total of 193 students participated. A large majority of the students were satisfied with the interaction (mean 4.36), the fifth year students rated the interaction better and showed higher satisfaction values. The students who reached a correct diagnosis rated this technology more positively. Our research suggests that the incorporation of this technology in dental curricula would be positively valued by students and would also ensure their training and adaptation to new technological developments.

Effect of an endodontic e-learning application on students' performance during their first root canal treatment on real patients: a pilot study

BACKGROUND

E-learning has found its way into dental teaching in general and endodontic teaching in particular. The present study aimed to implement a newly developed multimedia learning application and assess its effect on students' first root canal treatment on real patients. With the COVID-19 outbreak, the application's performance was investigated during the pandemic.

METHODS

A total of 138 students in the initial clinical endodontic course participated in this study. The control group (n = 49) followed the traditional curriculum, including practice on artificial teeth and face-to-face teaching events. In addition to the traditional curriculum, test group 1 (n = 54) had access to an endodontic e-learning application containing videos demonstrating artificial teeth and patient cases. With the COVID-19 outbreak, test group 2 (n = 35) had no face-to-face teaching; however, endodontic patient treatments were included. The quality of students' first root canal treatment on real patients was compared using performance and radiographic assessment items. Statistical analysis was done using Kruskal-Wallis and chi-squared tests. Test groups received a questionnaire to assess the learning application. Test group 2 also completed a COVID-19-specific survey to measure students' perceptions of how the pandemic affected their endodontic education.

RESULTS

The results of endodontic treatments were significantly better for test group 1 (P < 0.001) and 2 (P < 0.001) than for the control group. Likewise, there were significantly fewer treatment errors in test group 1 (P < 0.001) and 2 (P < 0.001). No significant differences were found between test groups 1 and 2. Students of the test groups positively evaluated the e-learning application. Students of test group 2 expressed their fear of negative impacts on their course performance.

CONCLUSION

The e-learning application was well-received and seemed to improve endodontic education. The results imply that the quality of education may be maintained by implementing e-learning to compensate for face-to-face teaching. As no difference was found between online and face-to-face teaching, students' and lecturers' concerns that endodontic education is suffering because of the pandemic may be eased.

Responding to COVID-19: Developing a Virtual "On-Campus" Experience for Adult-Geriatric Acute Care Nurse Practitioner Students

BACKGROUND

The coronavirus disease 2019 pandemic prevented in-person activities at colleges and universities in the spring/summer 2020 semester. Therefore, adult-geriatric acute care nurse practitioner students were unable to have on-campus clinical experiences.

METHOD

An innovative virtual experience was developed, using synchronous platforms for lectures and a virtual patient (VP) encounter.

RESULTS

Eight students participated in the experience, composed of three interactive lectures and a VP encounter. Students spent an average of 24.88 minutes (range = 20.88 to 35.48) with the VP, followed by debriefing. Students who became frustrated with the technology were identified as those who did not perform the practice session within the virtual platform.

CONCLUSION

Faculty determined that the virtual experience was a success. They were able to evaluate students' critical thinking and clinical decision-making. Next steps include refinement of the avatar platform as well as forcing completion of a practice session prior to the actual synchronous graded activity. [J Nurs Educ. 2021;60(10):586-589.].

Effectiveness of Virtual Reality and Interactive Simulators on Dental Education Outcomes: Systematic Review

In recent years, virtual reality and interactive digital simulations have been used in dental education to train dental students before interacting with real patients. Scientific evidence presented the application of virtual technology in dental education and some recent publications suggested that virtual and haptic technologies may have positive effects on dental education outcomes. The aim of this systematic review was to determine whether virtual technologies have positive effects on dental education outcomes and to explore the attitudes of dental students and educators toward these technologies. A thorough search was conducted in PubMed, Scopus, MEDLINE (via EBSCO), The Cochrane Library (via Wiley), Web of Science Core Collection (via Thomson Reuters), and Dentistry and Oral Science source (via EBSCO) using the keywords (student, dental) AND (education, dental) AND (virtual reality) OR (augmented reality) OR (haptics) OR (simulation) AND (dentistry) OR (dental medicine). The quality of the reported information was assessed following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement for systematic reviews. A total of 73 publications were considered for this review. Fifty-two of the selected studies showed significant improvement in educational outcomes and virtual technologies were positively perceived by all the participants. Within the limitations of this review, virtual technology appears to improve education outcomes in dental students. Further studies with larger samples and longer term clinical trials are needed to substantiate this potential positive impact of various virtual technologies on dental education outcomes.

Student performance comparisons for a critical thinking skill set (technology decision-making) for classroom and remote (Zoom) facilitation

A comparison of student learning in a critical thinking exercise for technology decision-making occurred with the onset of coronavirus and the switch from face-to-face to distance with Zoom. Literature on explicit critical thinking skill sets is scant in any format, including distance learning. While face-to-face and Zoom have similarities, seizing this opportunity for comparison can set the stage to determine soundness of distance learning in critical thinking on a preliminary basis. The learning outcome, learning guide and assessment instrument remained the same for the exercise in both formats; student teams presented analyses of different technologies with assessment by 2 faculty as before. Forty students had not completed the exercise when the coronavirus shut down occurred. Students performed at as high a level using virtual/Zoom as with face-to-face.

COVID-19 pandemic and the impact on dental education: discussing current and future perspectives

Due to the COVID-19 pandemic crisis, many dental schools and instructors are rethinking the way they teach and interact with students. New perspectives regarding a change in face-to-face activities, social isolation and the reformulation of clinical activities result in a transition toward e-learning and e-teaching processes. In this review, we discuss some favorable aspects and difficulties associated with virtual teaching and learning, searching for available tools and techniques as well as new perspectives.
