Background and Aims: simulators are widely used in occupations where practice in authentic environments would involve high human or economic risks. surgical procedures can be simulated by increasingly complex and expensive techniques. this review gives an update on computer-based virtual reality (vr) simulators in training for laparoscopic cholecystectomies.Materials and Methods: from leading databases (medline, cochrane, embase), randomised or controlled trials and the latest systematic reviews were systematically searched and reviewed. twelve randomised trials involving simulators were identified and analysed, as well as four controlled studies. furthermore, seven studies comparing black boxes and simulators were included.Results: the results indicated any kind of simulator training (black box, vr) to be beneficial at novice level. after vr training, novice surgeons seemed to be able to perform their first live cholecystectomies with fewer errors, and in one trial the positive effect remained during the first ten cholecystectomies. no clinical follow-up data were found. optimal learning requires skills training to be conducted as part of a systematic training program. no data on the cost-benefit of simulators were found, the price of a vr simulator begins at eur 60 000.Conclusions: theoretical background to learning and limited research data support the use of simulators in the early phases of surgical training. the cost of buying and using simulators is justified if the risk of injuries and complications to patients can be reduced. Developing surgical skills requires repeated training. in order to achieve optimal learning a validated training program is needed.
BackgroundVideo analyses of real-life newborn resuscitations have shown that Neonatal Resuscitation Program (NRP) guidelines are followed in fewer than 50 % of cases. Multidisciplinary simulation is used as a first-rate tool for the improvement of teamwork among health professionals. In the study we evaluated the impact of the crisis resource management (CRM) and anesthesia non-technical skills instruction on teamwork during simulated newborn emergencies.MethodsNinety-nine participants of two delivery units (17 pediatricians, 16 anesthesiologists, 14 obstetricians, 31 midwives, and 21 neonatal nurses) were divided to an intervention group (I-group, 9 teams) and a control group (C-group, 6 teams). The I-group attended a CRM and ANTS instruction before the first scenario. After each scenario the I-group performed either self- or peer-assessment depending on whether they had acted or observed in the scenario. All the teams participated in two and observed another two scenarios. All the scenarios were video-recorded and scored by three experts with Team Emergency Assessment Measure (TEAM). SPSS software and nlme package were used for the statistical analyses.ResultsThe total TEAM scores of the first scenario between the I- and C-group did not differ from each other. Neither there was an increase in the TEAM scoring between the first and second scenario between the groups. The CRM instruction did not improve the I-group’s teamwork performance. Unfortunately the teams were not comparable because the teams had been allowed to self-select their members in the study design. The total TEAM scores varied a lot between the teams. Mixed-model linear regression revealed that the background of the team leader had an impact on differences of the total teamwork scores (D = 6.50, p = 0.039). When an anesthesia consultant was the team leader the mean teamwork improved by 6.41 points in comparison to specialists of other disciplines (p = 0.043).ConclusionThe instruction of non-technical skills before simulation training did not enhance the acquisition of teamwork skills of the intervention groups over the corresponding set of skills of the control groups. The teams led by an anesthesiologist scored the best. Experience of team leaders improved teamwork over the CRM instruction.
New attitudes to medical ethics and demands for efficiency have brought increased attention to surgical skills and training. It is important to characterize the expertise and skill involved in the multidimensional surgical profession. At a time of change, there is a need to discuss the nature of surgical expertise, and also the prospects for resident training, with special reference to new minimally invasive techniques (MIS). In this paper, we selectively review knowledge on surgical expertise and the specific demands placed on a skilled MIS surgeon. In addition, the review contains a selection of studies from those areas that have been seen as important for the future of training in surgery.
Abstract. Surgical There also seem to be grounds for connecting user support into structured simulator training program.
BackgroundBased on common geography, sociopolitics, epidemiology, and healthcare services, the Nordic countries could benefit from increased collaboration and uniformity in the development of simulation-based learning (SBL). To date, only a limited overview exists on the Nordic research literature on SBL and its progress in healthcare education. Therefore, the aim of this study is to fill that gap and suggest directions for future research.MethodsAn integrative review design was used. A search was conducted for relevant research published during the period spanning from 1966 to June 2016. Thirty-seven studies met the inclusion criteria. All included studies were appraised for quality and were analyzed using thematic analysis.ResultsThe Nordic research literature on SBL in healthcare revealed that Finland has published the greatest number of qualitative studies, and only Sweden and Norway have published randomized control trials. The studies included interprofessional or uniprofessional teams of healthcare professionals and students. An assessment of the research design revealed that most studies used a qualitative or a descriptive design. The five themes that emerged from the thematic analysis comprised technical skills, non-technical skills, user experience, educational aspects, and patient safety.ConclusionThis review has identified the research relating to the progress of SBL in the Nordic countries. Most Nordic research on SBL employs a qualitative or a descriptive design. Shortcomings in simulation research in the Nordic countries include a lack of well-designed randomized control trials or robust evidence that supports simulation as an effective educational method. In addition, there is also a shortage of studies focusing on patient safety, the primary care setting, or a combination of specialized and primary care settings. Suggested directions for future research include strengthening the design and methodology of SBL studies, incorporating a cross-country comparison of studies using simulation in the Nordic countries, and studies combining specialized and primary care settings.Electronic supplementary materialThe online version of this article (10.1186/s41077-018-0071-8) contains supplementary material, which is available to authorized users.
