“…The key strengths of this scoping review were that it allowed for the synthesis of a broader range of evidence, whilst still maintaining systematic methods to undertake screening, study selection and data extraction. The study provides a broad insight into what is currently known about the range of VR use for ICU staff training, which may not have been possible under more stringent inclusion criteria of a systematic review (Ranganathan & Aggarwal, 2020). A further strength is that the review employed an evidence based theoretical framework to evaluate the current phases of development within existing research, using the methodology of VR clinical trials classification and the Kirkpatrick model (Kirkpatrick, 1998).…”

Background: The use of virtual reality (VR) in medical education allows learners to make mistakes safely without risk to patients and to refine a range of clinical skills by repetition. However, there is still wide variability both between, and within countries regarding the amount of training delivered using VR, particularly in relation to intensive care medicine Objectives: To identify the range of uses, phase of development and effectiveness of VR for intensive care unit (ICU) staff training. Methods: The review followed the scoping review framework set out by Levac et al. (2010). A multi-database search was undertaken. All study types were included if they explored the use of VR for intensive care staff (ICU) staff training. Full paper screening, data extraction and assessment of bias was carried out by a single reviewer with verification by a second reviewer. A narrative synthesis was chosen to summarize the data.Results: The search strategy identified 647 records. Following the removal of duplicates, screening of titles, abstracts and full texts, five studies were included. VR for ICU training has primarily focused on skill acquisition for surgical procedures. The majority of studies in this area were classified to be at an early stage of assessing acceptability, tolerability and efficacy. There was very low-quality evidence that VR for ICU training is effective.Conclusions: Studies have explored the use of VR for a small number of surgical procedures and emergency patient scenarios. VR for ICU training demonstrates some potential, however further development and high-quality research is required.Research relating to virtual reality for ICU staff training is currently of weak methodological quality and as such, no recommendations to clinical practise can be made. Wherever possible when using VR for ICU staff training it should be utilized as part of a high-quality study.

“…We discussed the steps involved in conducting a systematic review in a recent article. [ 1 ] If the systematic review reveals that there are an adequate number of studies with shared characteristics, then the reviewers may consider performing a formal meta-analysis. The systematic review process ensures that the meta-analysis includes data from all the available studies that fulfill certain selection and/or quality criteria, on the question being studied, in an unbiased manner.…”

“…In a previous article in this series, we looked at systematic reviews – their methods, uses, and limitations. [ 1 ] Systematic reviews are frequently followed by the use of a mathematical or statistical technique to pool the data from individual studies included in the review, to obtain a single summary measure of effect. This technique, known as meta-analysis, is the focus of this article.…”
