Virtual reality (VR) training has been shown previously to improve intraoperative performance during part of a laparoscopic cholecystectomy. The aim of this study was to assess the effect of proficiency-based VR training on the outcome of the first 10 entire cholecystectomies performed by novices. Thirteen laparoscopically inexperienced residents were randomized to either (1) VR training until a predefined expert level of performance was reached, or (2) the control group. Videotapes of each resident’s first 10 procedures were reviewed independently in a blinded fashion and scored for predefined errors. The VR-trained group consistently made significantly fewer errors ( P = .0037). On the other hand, residents in the control group made, on average, 3 times as many errors and used 58% longer surgical time. The results of this study show that training on the VR simulator to a level of proficiency significantly improves intraoperative performance during a resident’s first 10 laparoscopic cholecystectomies.

Background Previous studies have shown a correlation between previous video game experience and performance in minimally invasive surgical simulators. The hypothesis is that systematic video game training with high visual-spatial demands and visual similarity to endoscopy would show a transfer effect on performance in virtual reality endoscopic surgical simulation. Methods A prospective randomized study was performed. Thirty surgical novices were matched and randomized to five weeks of systematic video game training in either a first-person shooter game (Half Life) with high visual-spatial demands and visual similarities to endoscopy or a video game with mainly cognitive demands (Chessmaster). A matched control group ( n  = 10) performed no video game training during five weeks. Performance in two virtual reality endoscopic surgical simulators (MIST-VR and GI Mentor II) was measured pre- and post-training. Before simulator training we also controlled for students’ visual-spatial ability, visual working memory, age, and previous video game experience. Results The group training with Half Life showed significant improvement in two GI Mentor II variables and the MIST-VR task MD level medium. The group training with Chessmaster only showed an improvement in the MIST-VR task. No effect was observed in the control group. As recently shown in other studies, current and previous video game experience was important for simulator performance. Conclusions Systematic video game training improved surgical performance in advanced virtual reality endoscopic simulators. The transfer effect increased when increasing visual similarity. The performance in intense, visual-spatially challenging video games might be a predictive factor for the outcome in surgical simulation.

Background Operating rooms have become more technically complex due to new advanced procedures, which has increased demands on teamwork in the operating room. In response, team training has been proposed to improve team performance, workplace culture, and patient safety. We developed and delivered a simulation-based team training course for entire professional surgical teams. This type of intervention has been proposed by researchers but has not been widely published. The aims of this intervention study were to examine participants’ reactions to the course in terms of their motivation for the training and their self-efficacy in relation to their performance, as well as their views on transferring the lessons learned in the course to their workplace. Methods In a prospective mixed-methods intervention study, operating room professionals participated in a full-day simulation-based teamwork training course. Learning objectives were nontechnical skills, specifically communication and collaboration across the team. Seventy-one staff members representing 5 operating room professions were included, and the average work experience of participants was 6 years. Quantitative data on self-efficacy and situational motivation were collected by questionnaires before and after training. Qualitative data were collected through 5 focus group interviews that took place in direct relation to the courses and included a total of 31 participants. Transcripts were coded and analyzed using thematic analysis. Results All occupations showed a similar pattern in terms of increases in self-efficacy and intrinsic motivation after the training. Analysis of the qualitative data showed that training in one’s profession and in authentic multiprofessional teams was important factors for motivation. Participating staff described an awareness of undesirable communication barriers in surgical teams that can lead to risks for patients. Systematic training was definitely perceived as a means to reduce barriers and improve communication and collaboration. Conclusion Simulation-based training was equally well received by all professional groups. Our results confirm the feasibility of this type of training for professional teams and promising opportunities for improving teamwork skills. The qualitative data reveal both opportunities and limitations for transferring the learning experiences to the workplace.

Contemporary learning technologies, such as massively multiplayer virtual worlds (MMVW), create new means for teaching and training. However, knowledge about the effectiveness of such training is incomplete, and there are no data regarding how students experience it. Cardiopulmonary resuscitation (CPR) is a field within medicine in high demand for new and effective training modalities. In addition to finding a feasible way to implement CPR training, our aim was to investigate how a serious game setting in a virtual world using avatars would influence medical students' subjective experiences as well as their retention of knowledge. An MMVW was refined and used in a study to train 12 medical students in CPR in 3-person teams in a repeated fashion 6 months apart. An exit questionnaire solicited reflections over their experiences. As the subjects trained in 4 CPR scenarios, measurements of self-efficacy, concentration, and mental strain were made in addition to measuring knowledge. Engagement modes and coping strategies were also studied. Parametric and nonparametric statistical analyses were carried out according to distribution of the data. The majority of the subjects reported that they had enjoyed the training, had found it to be suitable, and had learned something new, although several asked for more difficult and complex scenarios as well as a richer virtual environment. The mean values for knowledge dropped during the 6 months from 8.0/10 to 6.25/10 (P = .002). Self-efficacy increased from before to after each of the two training sessions, from 5.9/7 to 6.5/7 (P = .01) after the first and from 6.0/7 to 6.7/7 (P = .03) after the second. The mean perceived concentration value increased from 54.2/100 to 66.6/100 (P = .006), and in general the mental strain was found to be low to moderate (mean = 2.6/10). Using scenario-based virtual world team training with avatars to train medical students in multi-person CPR was feasible and showed promising results. Although we found no evidence of stimulated recall of CPR procedures in our test-retest study, the subjects were enthusiastic and reported increased concentration during the training. We also found that subjects' self-efficacy had increased after the training. Despite the need for further studies, these findings imply several possible uses of MMVW technology for future emergency medical training.

Background Teamwork—that is, collaboration and communication—is an important factor for safe healthcare, but professions perceive the quality of teamwork differently. Objective To examine the relationship between simulation-based team training (SBTT) and different professions’ self-efficacy, experienced quality of collaboration and communication, perceptions of teamwork and safety, together with staff turnover. Methods All staff (n=151; physicians, nurses and nurse assistants) in an intensive care unit (ICU) at a university hospital were systematically trained over 2 years. Data on individual self-efficacy were measured using the self-efficacy questionnaire; the experienced quality of collaboration and communication, teamwork climate, safety climate and perception of working conditions were sampled using the ICU version of the safety attitudes questionnaire (SAQ). Staff turnover and sick leave was measured using the hospital's staff administration system for the intervention ICU and a control ICU in the same hospital. Results The perception of safety differed between professions before training. Nurses’ and physicians’ mean self-efficacy scores improved, and nurse assistants’ perceived quality of collaboration and communication with physician specialists improved after training. Nurse assistants’ perception of the SAQ factors teamwork climate, safety climate and working conditions were more positive after the project as well as nurses’ perception of safety climate. The number of nurses quitting their job and nurse assistants’ time on sick leave was reduced in comparison to the control ICU during the study period. Limitations Results for SAQ factors must be interpreted with caution given that Cronbach's α and inter-correlations for the SAQ factors showed lower values than benchmarking data. Conclusions All team members benefited from the SBTT in an authentic composed team, but this was expressed differently for the respective professions.

To compare medical students' and residents' knowledge retention of assessment, diagnosis and treatment procedures, as well as a learning experience, of patients with spinal trauma after training with either a Virtual Patient case or a video-recorded traditional lecture. A total of 170 volunteers (85 medical students and 85 residents in orthopedic surgery) were randomly allocated (stratified for student/resident and gender) to either a video-recorded standard lecture or a Virtual Patient-based training session where they interactively assessed a clinical case portraying a motorcycle accident. The knowledge retention was assessed by a test immediately following the educational intervention and repeated after a minimum of 2 months. Participants' learning experiences were evaluated with exit questionnaires. A repeated-measures analysis of variance was applied on knowledge scores. A total of 81% (n = 138) of the participants completed both tests. There was a small but significant decline in first and second test results for both groups (F = 18.154, p = 0.00). However, no significant differences in short-term and long-term knowledge retention were observed between the two teaching methods. The Virtual Patient group reported higher learning experience levels in engagement, stimulation, general perception, and expectations. Participants' levels engagement were reported in favor of the VP format. Similar knowledge retention was achieved through either a Virtual Patient or a recorded lecture.

Background Multiplayer virtual world (MVW) technology creates opportunities to practice medical procedures and team interactions using serious game software. This study aims to explore medical students’ retention of knowledge and skills as well as their proficiency gain after pre-training using a MVW with avatars for cardio-pulmonary resuscitation (CPR) team training. Methods Three groups of pre-clinical medical students, n = 30, were assessed and further trained using a high fidelity full-scale medical simulator: Two groups were pre-trained 6 and 18 months before assessment. A reference control group consisting of matched peers had no MVW pre-training. The groups consisted of 8, 12 and 10 subjects, respectively. The session started and ended with assessment scenarios, with 3 training scenarios in between. All scenarios were video-recorded for analysis of CPR performance. Results The 6 months group displayed greater CPR-related knowledge than the control group, 93 (±11)% compared to 65 (±28)% (p < 0.05), the 18 months group scored in between (73 (±23)%). At start the pre-trained groups adhered better to guidelines than the control group; mean violations 0.2 (±0.5), 1.5 (±1.0) and 4.5 (±1.0) for the 6 months, 18 months and control group respectively. Likewise, in the 6 months group no chest compression cycles were delivered at incorrect frequencies whereas 54 (±44)% in the control group (p < 0.05) and 44 (±49)% in 18 months group where incorrectly paced; differences that disappeared during training. Conclusions This study supports the beneficial effects of MVW-CPR team training with avatars as a method for pre-training, or repetitive training, on CPR-skills among medical students.

Approximately 300,000 people suffer sudden cardiac arrest (SCA) annually in the United States. Less than 30% of out-of-hospital victims receive cardiopulmonary resuscitation (CPR) despite the American Heart Association training over 12 million laypersons annually to conduct CPR. New engaging learning methods are needed for CPR education, especially in schools. Massively multiplayer virtual worlds (MMVW) offer platforms for serious games that are promising learning methods that take advantage of the computer capabilities of today's youth (ie, the digital native generation). Our main aim was to assess the feasibility of cardiopulmonary resuscitation training in high school students by using avatars in MMVM. We also analyzed experiences, self-efficacy, and concentration in response to training. In this prospective international collaborative study, an e-learning method was used with high school students in Sweden and the United States. A software game platform was modified for use as a serious game to train in emergency medical situations. Using MMVW technology, participants in teams of 3 were engaged in virtual-world scenarios to learn how to treat victims suffering cardiac arrest. Short debriefings were carried out after each scenario. A total of 36 high school students (Sweden, n=12; United States, n=24) participated. Their self-efficacy and concentration (task motivation) were assessed. An exit questionnaire was used to solicit experiences and attitudes toward this type of training. Among the Swedish students, a follow-up was carried out after 6 months. Depending on the distributions, t tests or Mann-Whitney tests were used. Correlation between variables was assessed by using Spearman rank correlation. Regression analyses were used for time-dependent variables. The participants enjoyed the training and reported a self-perceived benefit as a consequence of training. The mean rating for self-efficacy increased from 5.8/7 (SD 0.72) to 6.5/7 (SD 0.57, P<.001). In the Swedish follow-up, it subsequently increased from 5.7/7 (SD 0.56) to 6.3/7 (SD 0.38, P=.006). In the Swedish group, the mean concentration value increased from 52.4/100 (SD 9.8) to 62.7/100 (SD 8.9, P=.05); in the US group, the concentration value increased from 70.8/100 (SD 7.9) to 82.5/100 (SD 4.7, P<.001). We found a significant positive correlation (P<.001) between self-efficacy and concentration scores. Overall, the participants were moderately or highly immersed and the software was easy to use. By using online MMVWs, team training in CPR is feasible and reliable for this international group of high school students (Sweden and United States). A high level of appreciation was reported among these adolescents and their self-efficacy increased significantly. The described training is a novel and interesting way to learn CPR teamwork, and in the future could be combined with psychomotor skills training.

Situation awareness (SA) is a critical non-technical skill which affects outcome during emergency medical endeavors. Using a modified self-report instrument a significant increase of SA was found during multiplayer virtual world CPR team training among 12 medical students. Further a correlation between SA and attention was noted. Being a vital factor during the process of video-game play, we argue that this skill is suitably practiced using this training method.

In addition to technical skills, nontechnical factors appear to influence surgical results. This study aims to analyze how visuospatial ability, self-efficacy, and flow are associated with simulated laparoscopic performance of residents in obstetrics and gynecology (OBGYN). In this cohort study, 28 residents in obstetrics and gynecology were tested for visuospatial ability and self-efficacy prior to simulator training. All participants subsequently conducted a basic set of tasks in the simulator. Self-efficacy, once again, and flow were assessed after training. Nineteen of the subjects then completed a 2-day course with identical simulator tasks, although now to a predefined credential level. Visuospatial ability correlated with simulator performance in the technically most advanced simulator task in the basic set (“total time,” r  = −0.40, p  = 0.039). Flow correlated with: “right instrument pathway”( r  = −0.40, p  = 0.004) in that same task and with the 2-day overall training results ( r  = −0.56, p  = 0.017). Self-efficacy correlated with the 2-day result ( r  = −0.56, p  = 0.013) and significantly improved after training ( p  = 0.011). When constructing a curriculum for OBGYN residents, visuospatial abilities and non-technical factors like flow and self-efficacy should be considered.
